    Die Wiedervereinigung stellte auch die Statistik vor große Aufgaben. Die als Organ der staatlichen Planung staatsnah orientierte Statistik der DDR musste auf das zur Neutralität und wissenschaftlichen Unabhängigkeit verpflichtete System der Bundesrepublik umgestellt werden. Ebenso verlangten die Universitäten eine Neuorientierung. Die Deutsche Statistische Gesellschaft hat sich vor allem dreier Aufgaben mit großem Engagement, aber auch mit Bedachtsamkeit angenommen: Aufnahme und Integration der Statistiker aus den neuen Bundesländern in die Gesellschaft, Begleitung der Neuausrichtung des Faches Statistik an deren Hochschulen und Sicherung sowie Nutzung von Datenbeständen der ehemaligen DDR.

  3. Time Travel: Deutsch vs. Teleportation

    NASA Astrophysics Data System (ADS)

    Svetlichny, George

    2011-12-01

    The quantum teleportation protocol can be used to probabilistically simulate a quantum circuit with backward-in-time connections. This allows us to analyze some conceptual problems of time travel in the context of physically realizable situations free of paradoxes. As an example one can perform encrypted measurements of future states for which the decryption key becomes available in the future. Likewise, the gauge-like freedom of locally changing the direction of time flow in quantum circuits can lead to conceptual and computational simplifications. I contrast this situation with Deutsch's treatment of quantum mechanics in the presence of closed time-like curves pointing out some of its deficiencies and problems.

    2001-10-01

    The two-atom correlation scheme originally proposed by Davidovich, Brune, Raimond, and Haroche for measuring the decoherence of a mesoscopic superposition of coherent states of a QED cavity field is shown to be equivalent to a quantum computer solving Deutsch's problem. Using the existing analysis of decoherence in the Master equation formalism, and other important losses in this system, the final probability for obtaining the correct result for the computation is found in terms of the time period between atom traversals, the number of photons in the cavity, and the precision of the atomic velocity. The error due to decoherence in this system amounts to a phase error, and in the Master equation approach is a linear effect at small time scales. By explicitly considering the dynamics of the decoherence process when the system is coupled to a bath of oscillators with finite mode cutoff the error due to decoherence is found to decrease significantly and becomes a quadratic effect at short-time scales.

  7. Understanding Deutsch's probability in a deterministic multiverse

    NASA Astrophysics Data System (ADS)

    Greaves, H.

    2004-09-01

    Difficulties over probability have often been considered fatal to the Everett interpretation of quantum mechanics. Here I argue that the Everettian can have everything she needs from 'probability' without recourse to indeterminism, ignorance, primitive identity over time or subjective uncertainty: all she needs is a particular rationality principle. The decision-theoretic approach recently developed by Deutsch and Wallace claims to provide just such a principle. But, according to Wallace, decision theory is itself applicable only if the correct attitude to a future Everettian measurement outcome is subjective uncertainty. I argue that subjective uncertainty is not available to the Everettian, but I offer an alternative: we can justify the Everettian application of decision theory on the basis that an Everettian should care about all her future branches. The probabilities appearing in the decision-theoretic representation theorem can then be interpreted as the degrees to which the rational agent cares about each future branch. This reinterpretation, however, reduces the intuitive plausibility of one of the Deutsch-Wallace axioms (measurement neutrality).

    It is with deep sadness and regret that we note the passing of our dear friend and colleague Prof. Lynne K. Deutsch. Lynne died on 2 April 2004 after a protracted illness and lengthy battle with complications caused by the blood disease Polycythaemia Vera. Lynne was born in Chicago on 26 November 1956 to Victor and Ailsa Deutsch. She lived with her family in the town of Morton Grove, IL until she was 8 years old, when they moved to Beverly Hills, CA. She was an outgoing child who played basketball and excelled in her studies. She graduated from Beverly Hills High School at the age of 16 after completing all high school requirements in only three years. Lynne had a beautiful singing voice, and was in the chorus in high school and college. Lynne earned her first bachelor's degree in philosophy from the University of California at Berkeley in 1977. She then returned to Berkeley and received a second bachelor's degree, this time in physics, in 1981. She was a graduate student and teaching assistant at MIT and earned an MS in physics from MIT in 1983. Lynne then attended the astronomy graduate program at Harvard University, where she earned her MA in 1985 and PhD in 1990. During her degree studies she began crafting mid-infrared instrumentation. These instruments were destined to be used by a host of eager observers to discover, identify, and study many emissions from the Solar System, and galactic and extragalactic sources. Lynne was a National Research Council Post-doctoral Fellow at NASA Ames Research Center from 1990 - 1992, where she played an important role in the development of the Smithsonian Astrophysical Observatory/University of Arizona Mid-Infrared Array Camera (MIRAC), a well-known and much sought after instrument frequently used in studies of Mercury, Jupiter, the Moon, planetary nebulae, star formation regions, galactic center, young stellar objects, and extragalactic objects.

  11. Two cases of induced insanity. Helene Deutsch, Cambridge, Mass.

    PubMed

    Roazen, P

    1981-01-01

    "Two cases of induced insanity", hitherto untranslated, was Helene Deutsch's first (1918) psychoanalytic paper; she presented Freud with a copy of it during the beginning of her analysis with him. As an experienced clinician who had studied under both Wagner von Jauregg in Vienna and Emil Kraepelin in Munich, Deutsch observed these cases during World War I as the University of Vienna's psychiatric facilities. Although the general reading public knows her best for her The Psychology of Women, she also wrote some well-known clinical papers; and it is characteristic of her that she brought these two cases without excessive theoretical speculation. In "Two cases in induced insanity" Deutsch described some of the strains of the wartime situation, and how whole families could join in hysterical confabulations in order to cope with emotional distress. One of her most famous later clinical contribution had to do with the emotional impoverishment of 'as if' personalities and their specific suggestibility. In other papers she continued her early concern with disturbed identification. As one examines Deutsch's work it is possible to fill out the history of psychoanalytic psychology. Without ignoring her later increase in theoretical sophistication, in "Two cases of induced insanity" we find Deutsch remarkably tolerant in her willingness to suspend judgement about the sources and fate of morbid thinking. A key therapeutic recommendation of hers was to separate the family members to allow their reality to return. Like some recent critics of undue diagnostic name-calling she advocated hesitation in discerning of disease entities as well as cautionary approach to treatment. The nature of familial love may leave everyone "normal" prone to disturbances which are not necessarily to be treated as a psychiatric illness. This example of one of Deutsch's first professional essays reflects the early thinking of a giant in psychoanalysis. She followed Freud in the conviction that the

  15. Measurement Theory in Deutsch's Algorithm Based on the Truth Values

    NASA Astrophysics Data System (ADS)

    Nagata, Koji; Nakamura, Tadao

    2016-08-01

    We propose a new measurement theory, in qubits handling, based on the truth values, i.e., the truth T (1) for true and the falsity F (0) for false. The results of measurement are either 0 or 1. To implement Deutsch's algorithm, we need both observability and controllability of a quantum state. The new measurement theory can satisfy these two. Especially, we systematically describe our assertion based on more mathematical analysis using raw data in a thoughtful experiment.

  16. Using the Deutsch-Jozsa algorithm to partition arrays

    NASA Astrophysics Data System (ADS)

    Lipovaca, Samir

    2010-03-01

    Using the Deutsch-Jozsa algorithm, we will develop a method for solving a class of problems in which we need to determine parts of an array and then apply a specified function to each independent part. Since present quantum computers are not robust enough for code writing and execution, we will build a model of a vector quantum computer that implements the Deutsch-Jozsa algorithm from a machine language view using the APL2 programming language. The core of the method is an operator (DJBOX) which allows evaluation of an arbitrary function f by the Deutsch-Jozsa algorithm. Two key functions of the method are GET/PARTITION and CALC/WITH/PARTITIONS. The GET/PARTITION function determines parts of an array based on the function f. The CALC/WITH/PARTITIONS function determines parts of an array based on the function f and then applies another function to each independent part. We will imagine the method is implemented on the above vector quantum computer. We will show that the method can be successfully executed.

  17. Optimal simulation of Deutsch gates and the Fredkin gate

    NASA Astrophysics Data System (ADS)

    Yu, Nengkun; Ying, Mingsheng

    2015-03-01

    In this paper, we study the optimal simulation of the three-qubit unitary using two-qubit gates. First, we completely characterize the two-qubit gate cost of simulating the Deutsch gate (controlled-controlled gate) by generalizing our result on the two-qubit cost of the Toffoli gate. The function of any Deutsch gate is simply a three-qubit controlled-unitary gate and can be intuitively explained as follows: The gate outputs the states of the two control qubits directly, and applies the given one-qubit unitary u on the target qubit only if both the states of the control qubits are |1 > . Previously, it was only known that five two-qubit gates are sufficient for implementing such a gate [Sleator and Weinfurter, Phys. Rev. Lett. 74, 4087 (1995), 10.1103/PhysRevLett.74.4087]. We show that if the determinant of u is 1, four two-qubit gates are optimal. Otherwise, five two-qubit gates are required. For the Fredkin gate (the controlled-swap gate), we prove that five two-qubit gates are necessary and sufficient, which settles the open problem introduced in Smolin and DiVincenzo [Phys. Rev. A 53, 2855 (1996), 10.1103/PhysRevA.53.2855].

  18. Implementing the Deutsch-Jozsa algorithm with macroscopic ensembles

    NASA Astrophysics Data System (ADS)

    Semenenko, Henry; Byrnes, Tim

    2016-05-01

    Quantum computing implementations under consideration today typically deal with systems with microscopic degrees of freedom such as photons, ions, cold atoms, and superconducting circuits. The quantum information is stored typically in low-dimensional Hilbert spaces such as qubits, as quantum effects are strongest in such systems. It has, however, been demonstrated that quantum effects can be observed in mesoscopic and macroscopic systems, such as nanomechanical systems and gas ensembles. While few-qubit quantum information demonstrations have been performed with such macroscopic systems, a quantum algorithm showing exponential speedup over classical algorithms is yet to be shown. Here, we show that the Deutsch-Jozsa algorithm can be implemented with macroscopic ensembles. The encoding that we use avoids the detrimental effects of decoherence that normally plagues macroscopic implementations. We discuss two mapping procedures which can be chosen depending upon the constraints of the oracle and the experiment. Both methods have an exponential speedup over the classical case, and only require control of the ensembles at the level of the total spin of the ensembles. It is shown that both approaches reproduce the qubit Deutsch-Jozsa algorithm, and are robust under decoherence.

    We have all witnessed the devastation of strokes on friends and family, especially the profound impact on the quality of life for people post-stroke. Over the past few years, remarkable progress has been made for first responders to identify and reduce the impact of strokes. Yet people post-stroke often experience the direct and indirect effects of the brain injury, including loss of motor function. Judith Deutsch and her multidisciplinary team at the University of Medicine and Dentistry of New Jersey are researching how virtual reality and videogames can improve balance, mobility, coordination, and stamina of stroke victims. I had the pleasure of meeting personally with Judy and her team in their impressive research center in Newark, NJ.

    PLISKOFF, S S; HAWKINS, T D

    1963-08-30

    Deutsch's theory of intracranial self-stimulation generates experimental predictions regarding the effects of both free stimulation of the brain and the pre-extinction training procedure on extinction behavior after rewarding stimulation of the brain. The results of one experiment confirmed the prediction regarding free stimulation; the other experiment did not provide the expected result. We concluded that Deutsch's theory, in its present form, is of restricted enerality.

  2. Deutsch's CTC Model and its Implications for the Foundations of Quantum Theory

    NASA Astrophysics Data System (ADS)

    Dunlap, Lucas

    This dissertation is an exploration of several issues surrounding David Deutsch's CTC model first introduced in his 1991 paper "Quantum Mechanics Near Closed Timelike Lines". Deutsch developed his model to account for the effects of quantum theory, which had been left out of classical discussions of time travel paradoxes. Deutsch's formulation of his model in terms of quantum computational circuits lends itself to being adopted in the quantum information community. The dissertation argues that the adoption of the D-CTC model entails the existence of Nonlocal Signaling, which is in conflict with a fundamental principle of the quantum information approach. In order to motivate this argument, in Chapter 2 I introduce a distinction between Nonlocal Signaling, and Superluminal Information Transfer. In the latter case, a carrier of information physically traverses the space between the distant communicating parties faster than the speed of light. Exploiting quantum entanglement to signal, however, need not have this feature. I term this Nonlocal Signaling. Chapter 3 is where I present the argument that D-CTCs entail Nonlocal Signaling, and examine the controversy surrounding this and related results. I argue that the resistance to these kinds of predictions in the literature is motivated by a commitment to the principles of quantum information theory, which are inappropriately applied here. Chapters 4 and 5 examine details of Deutsch's model. Chapter 4 argues that it presupposes a significant metaphysical picture that, when explicitly stated, makes a much less comfortable fit between D-CTCs and quantum information theory. Chapter 5 argues that, because of Deutsch's commitment to this metaphysical picture, he is committed to the existence of physical situations that are in every way indistinguishable from the paradoxes he attempts to rule out by adopting the model in the first place. In Chapter 6, I make some observations about the relationship between the quantum

  3. Against the empirical viability of the Deutsch-Wallace-Everett approach to quantum mechanics

    NASA Astrophysics Data System (ADS)

    Dawid, Richard; Thébault, Karim P. Y.

    2014-08-01

    The subjective Everettian approach to quantum mechanics presented by Deutsch and Wallace fails to constitute an empirically viable theory of quantum phenomena. The decision theoretic implementation of the Born rule realized in this approach provides no basis for rejecting Everettian quantum mechanics in the face of empirical data that contradicts the Born rule. The approach of Greaves and Myrvold, which provides a subjective implementation of the Born rule as well but derives it from empirical data rather than decision theoretic arguments, avoids the problem faced by Deutsch and Wallace and is empirically viable. However, there is good reason to cast doubts on its scientific value.

The function need not be Boolean. Simulations confirm that the algorithm works properly, opening the way toward quantum computing at room temperature based on the same clean-room technologies as those used for fabrication of very-large-scale integrated circuits.

    Despite early experimental tests of the Deutsch-Jozsa (DJ) algorithm, there have been only a very few nontrivial balanced functions tested for register number n>3. In this paper, we experimentally demonstrate the DJ algorithm in four- and five-qubit homonuclear spin systems by the nuclear-magnetic-resonance technique, by which we encode the one function evaluation into a long shaped pulse with the application of the gradient ascent algorithm. Our work, dramatically reducing the accumulated errors due to gate imperfections and relaxation, demonstrates a better implementation of the DJ algorithm.

    2010-06-01

    One of the longstanding attractions of the Deutsches Museum in Munich, Germany, has been its display of the apparatus associated with the discovery of nuclear fission. Although the discovery involved three scientists, Otto Hahn, Lise Meitner, and Fritz Strassmann, the fission display was designated for over 30 years as the Arbeitstisch von Otto Hahn (Otto Hahn’s Worktable), with Strassmann mentioned peripherally and Meitner not at all, and it was not until the early 1990s that the display was revised to include all three codiscoverers more equitably. I examine the creation of the fission display in the context of the postwar German culture of silencing the National Socialist past, and trace the eventual transformation of the display into a contemporary exhibit that more accurately represents the scientific history of the fission discovery.

    Nach anfänglichen Schwierigkeiten durch den 1. Weltkrieg erlangte die Deutsche Statistische Gesellschaft (DStatG) unter dem renommierten Statistiker und Vorsitzenden der DStatG, Friedrich Zahn, durch eine Vielzahl von Aktivitäten hohes Ansehen. Es gab Bestrebungen, Statistiker aus allen Arbeitsfeldern der Statistik in die DStatG zu integrieren, wobei die "Mathematische Statistik" nur zögerlich akzeptiert wurde (Konjunkturforschung, Zeitreihenanalyse). Nach der Machtübernahme 1933 durch Adolf Hitler geriet die DStatG in das Fahrwasser nationalsozialistischer Ideologie und Politik (Führerprinzip, Gleichschaltung des Vereinswesens). Damit war eine personelle Umstrukturierung in der DStatG verbunden. Politisch Missliebige und rassisch Verfolgte mussten die DStatG verlassen (Bernstein, Freudenberg, Gumbel u.a.). Unter den Statistikern gab es alle Abstufungen im Verhalten zum Regime von Ablehnung und zwangsweiser Anpassung über bereitwilliges Mitläufertum bis zu bewusster Täterschaft. Besonders die Bevölkerungsstatistik wurde durch die NS- Rassenpolitik auf lange Sicht diskreditiert. Im Rahmen von Wirtschaftsplanung und Aufrüstung wurden neue zukunftsträchtige statistische Modelle (Grünig, Bramstedt, Leisse) entwickelt.

  17. Vibrational molecular quantum computing: basis set independence and theoretical realization of the Deutsch-Jozsa algorithm.

    PubMed

    Tesch, Carmen M; de Vivie-Riedle, Regina

    2004-12-22

    The phase of quantum gates is one key issue for the implementation of quantum algorithms. In this paper we first investigate the phase evolution of global molecular quantum gates, which are realized by optimally shaped femtosecond laser pulses. The specific laser fields are calculated using the multitarget optimal control algorithm, our modification of the optimal control theory relevant for application in quantum computing. As qubit system we use vibrational modes of polyatomic molecules, here the two IR-active modes of acetylene. Exemplarily, we present our results for a Pi gate, which shows a strong dependence on the phase, leading to a significant decrease in quantum yield. To correct for this unwanted behavior we include pressure on the quantum phase in our multitarget approach. In addition the accuracy of these phase corrected global quantum gates is enhanced. Furthermore we could show that in our molecular approach phase corrected quantum gates and basis set independence are directly linked. Basis set independence is also another property highly required for the performance of quantum algorithms. By realizing the Deutsch-Jozsa algorithm in our two qubit molecular model system, we demonstrate the good performance of our phase corrected and basis set independent quantum gates.

    The study examines the nature, conditions, and outcomes of student learning from an organised guided tour in the Deutsches Museum in Munich. The instructional methods that best support students' cognitive and affective learning as well as how students' motivational and emotional states influence their achievement were investigated. A sample of 96 secondary school students took part in two different versions of a guided tour on an energy topic. The tours varied in the degree of support of students' active involvement, group work, and the variety of general activities offered during the tour. The data collected indicate that both tour versions led to an increase in student understanding of the visit topic to nearly the same extent. However, the version stimulating students' active participation, group work, and including a larger variety of activities aroused more positive attitudes. Students of the modified school programme showed higher interest and intrinsic motivation, felt more competent, and were less bored after the guided tour. In addition, the results suggest that students' visit-related emotional states predict the degree of their post-visit topic understanding, even when demographics and prior knowledge are taken into consideration.

    The Deutsch-Jozsa algorithm is experimentally demonstrated for three-qubit functions using pure coherent superpositions of Li{sub 2} rovibrational eigenstates. The function's character, either constant or balanced, is evaluated by first imprinting the function, using a phase-shaped femtosecond pulse, on a coherent superposition of the molecular states, and then projecting the superposition onto an ionic final state, using a second femtosecond pulse at a specific time delay.

  20. Quantum computers and reality: Deutsch's anti-positivist campaign for explanations-in-general, apart from his Many Worlds Interpretation.

    2002-04-01

    David Deutsch (Oxford University) is known for ``Deutsch's algorithmm"---for going beyond the initial ideas about quantum computing (QC) of Benioff, Bennett and Feynman, to describe a quantum Turing machine, and sparking today's widespread experimental research to actually build one. Deutsch does not accept the standard Copenhagen Interpretation (CI) of quantum mechanics (QM); he supports the Many Worlds Interpretation (MWI) and credits it for his insights. In his book, The Fabric of Reality, and numerous articles and talks, he argues that the the adoption of the MWI is phnecessary for making the advances required for quantum computing. His argues that physicists must resolutely take a ``realistic" viewpoint to its logical conclusions, and, that the MWI is phthe realistic theory. In response to ubiquitous assertions by the majority of physicists that ``both systems give the same numbers," and ``all physics does (or can do) is to predict the outcome of experiments," he argues strenuously for the importance of explanations in quantum physics, and to scientific progress in general. Hence, I argue that there are two, reasonably separable, layers here: (i) opposition to positivist and instrumentalist arguments against the validity and/or value of phany explanation(s) phas such, and (ii) an argument about just what is the correct explanation: the MWI over the CI. While establishing the validity of (i) may possibly undermine CI's spirit, nevertheless (i) can be strongly validated independent from complicatons of an overlap with issues of the interpretation of QM. I develop some simple, historical contradictions regarding point (i), (without passing judgement on Deutsch's MWI or involving the CI). For example, the majority viewpoint identifies its seemingly ``non- philosophical" and non-``methaphysical" mindset as archtypically ``scientific", while seemingly quite unaware of the theoretical difficuties with positivist notions of truth, such as the fact that the foundations

    The Deutsche Forschungsanstalt fur Psychiatrie (DFA) in Munich, one of the most important research institutes in the field of theoretical and clinical psychiatry, was founded in 1917 by Emil Kraepelin. Its financial existence between the world wars was assured by generous donations from the Jewish American scholar and philanthropist James Loeb. The scientific work done by Walther Spielmeyer (neuropathology), Felix Plaut (serology), Kurt Schneider (clinical psychiatry) and Ernst Rudin (psychiatric genetics) earned the DFA a reputation as an international center for psychiatry and neurology. During the 'Third Reich' Ernst Rudin cooperated with the National Socialist health system. His genetic concepts provided support for eugenic programmes such as forced sterilization of individuals with psychoses. These complex interactions underscore the importance of the DFA in understanding the recent history of medicine in Germany.

    Introduction: The German DRG system is annually adapted to the changing services provided. For the further development, the self-governing body and its DRG Institute (InEK) depend on participation of the users. Methods: For one of the DRG evaluation projects initiated by DGGG, cost and performance data for the year 2011 from 16 hospitals were available. After plausibility checks and corrections, analyses for service and cost homogeneity were performed. In cases of inadequate DRG-representation attributes were sought that would make an appropriate reimbursement possible. Conspicuities and potential solutions were checked for clinical plausibility. Results: 44 concrete modification proposals for further development of the G-DRG system were formulated and submitted in due time to the InEK. In addition, 3 modification proposals were addressed to the German Institute for Medical Documentation and Information (Deutsches Institut für Medizinische Dokumentation und Information, DIMDI) for further development of the diagnosis classification ICD-10-GM. For all modification proposals care was taken to minimise misdirected incentives and to reduce the potential for disputes with the cost bearers and their auditors services in settlements. Discussion: The publication of the G-DRG system 2014 shows which modification proposals have been realised. Essentially, an appropriate redistribution of the resources among the gynaecological and obstetrics departments is to be expected. The financial pressure that is caused by the generally inadequate financing of hospitals will not be reduced by a further development of the G-DRG system. PMID:24771931

    Objective This manuscript summarizes our surgical experience with the implantation of recent continuous-flow left ventricular assist devices (LVADs), with special emphasis on the HeartWare HVAD pump. Methods The HeartWare HVAD is, in our experience currently implanted in four different techniques: (I) “Classical” LVAD implantation with heart-lung machine and median sternotomy; (II) “Minimally-invasive” implantation without sternotomy and without heart-lung machine; (III) “Lateral implantation” to the descending aorta; (IV) Using two continuous-flow LVADs for implantable biventricular support. Results Five-hundred and four HeartWare HVADs have been implanted using the described techniques in our institution up to now. Conclusions The HeartWare HVAD is a versatile device. It has been found to be eminently suited to these four different modes of implantation. PMID:25452906

    An abiding mystery of the mind-body connection is that it should seem mysterious at all--an indication, perhaps, of how deeply conditioned we have been by "dualism." That doctrine, laid down more than three centuries ago by French philosopher Rene Descartes, sees mind and body as distinct entities, to be treated separately. It became the paradigm for medicine, and still dominates medical thinking.

    The competence network for viral hepatitis (HepNet) was founded in 2002 with funding from the German government and has influenced the research on viral hepatitis in Germany. HepNet collaborator sites have been involved in numerous national and international investigator-initiated, as well as industry-sponsored, phase 1-3 studies. Within the HepNet Study-House, many groundbreaking investor-initiated trials have been completed and are still ongoing. For example, the acute hepatitis C trials and trials on chronic hepatitis D (delta), which led to therapy optimization. Continuation of the competence network on viral hepatitis has been achieved by the foundation of the German Liver Foundation, which has been an external cooperation partner of the German Center for Infection Research (DZIF) for two years. The well-established HepNet Study-House acts here as the clinical trial platform for all DZIF hepatitis trials.

    2006-09-01

    During National Socialism, the politically motivated interest in psychiatric genetic research lead to the founding of research departments specialized in pathological-anatomical brain research, the two Kaiser Wilhelm-Institutes (KWI) in Berlin and Munich. The latter was indirectly provided with brain material by Bavarian State Hospitals, to three of which "Kinderfachabteilungen" (Special Pediatric Units) were affiliated. As children became victims of the systematically conducted child "euthanasia" in these Special Pediatric Units, this paper will address the question whether and to which extent the organs from victims of child "euthanasia" were used for (neuro-) pathological research at the KWI in Munich. By means of case studies and medical histories (with focus on the situation in Kaufbeuren-Irsee), I will argue that pediatric departments on a regular base delivered slide preparations, that the child "euthanasia" conduced in these departments systematically contributed to neuropathological research and that slide preparations from victims of child "euthanasia" were used in scientific publications after 1945.

    Soam discovered the drug Bromovalerylurea (or less BV) in 1907. After that, BV was imported in Japan in the latter part of the Meiji period as Western medicine. Under the influence of the First World War, in Japan, BV was domestic production. And BV are listed in JP V (1932), it is continued listing until the current JP X VI (2011). As a foreign pharmacopoeia which listed the BV, only in addition to the JP, there was a German Pharmacopoeia (DAB). During this time, the JP and DAB, the standards and test methods of BV, it was amended as shown in Table 1 and Table 2. The discrimination test and analysis test was defined based on the chemical properties of urea and isovaleric acid and bromine. Therefore, consistency was seen in the chemical criteria for test. From this it is understood that BV is Bromoisovalerateureido synthesized based on urea and isovaleric acid and bromine. This isovaleric acid is the active ingredient of Japanese Valerian and Valerian roots. BV is an organic synthetic urea derivative that was effectively improved organic synthesis isovaleric acid with respect to quality and efficacy surface. For this reason at the time that BV have been developed, it is an ideal new drug, it was described as a good medicine have no side effects. But to BV, there is a nature that it has tolerance, addictive, a dependency. In Japan after the Second World War, there was a lack of awareness about the nature of such BV. That it had become a system that masses can easily purchase the BV. Revision of the Pharmaceutical Affairs Law of 1960 against in this, selling regulation of BV is provided. However, for analgesic formulated with BV of dose observed in the Pharmaceutical Affairs Law, as generic drugs, selling is permitted, it is continuing until today. For this reason in recent years, long-term use of BV by self-judgment of the masses is frequent. And chronic bromine poisoning BV by this it have been a problem. Therefore regard to BV, always for their safety, including the overseas situation, I think it is important to seize the new knowledge and information. PMID:27149780

    17 adenovirus strains were found to be antigenically related to prototype Ad 15 by neutralization. No relationship to Ad 15, but to Ad 9 could be detected by hemagglutination-inhibition; we therefore named them Ad 15/H9 intermediate strains. After analysis of the genome by five different restriction enzymes, the fragment patterns obtained deviated widely from the prototype Ad 15, but only slightly from Ad 9. Differences could also be observed among the variants. After digestion by five restriction enzymes, altogether six genome types could be established among the 17 intermediate strains. To map the variations on the genome of the 15/H9 strains, two methods were employed: the double digestion of the DNA and DNA fragments together with the determination of the terminal fragments made it possible to construct a physical map. The second method depends on a particularity of adenoviruses: the DNA is covalently linked with a 55 kD protein at the 5' terminus. After digestion of the DNA, which does contain this protein, the terminal DNA fragments do not migrate into the agarose gel; after an additional digestion with pronase B, they do migrate into the gel. Thus the terminal fragments were determined by comparing the fragment patterns with and without previous pronase B treatment.

    Valerian has been used as a name for Japanese Valerian and European Valerian root. Valerian in the German market today was originally called Baldrian. Transitions in the standards and the test methods of Valerian root listed in the DAB were studied this time. Moreover, we compared these standards and test methods with those in the USP, BP, EP and JP. We also considered the pharmacology evaluation in Germany. At the time, the standards and test methods had content in accordance with the EP from DAB9 (1986) of the West Germany publication. It also agreed with the EP and BP of the same period. To date in the DAB, botanical features have been mainly derived from the discriminating characteristics of the Valerian root. In DAB9 (1986), standards and test methods were added to the content, enhancing it and making it more stringent. This is thought to have happened as a result of a new, academic finding showing an improvement in the pharmacology level. Valerian root has been listed continuously in the DAB. These listings suggest that Valerian root has continally been evaluated as a sedative. We think that the listing was connected with a relisting in the BP as a result of scientific communications between Britain and Germany, EC member nations, such as through EP publications. On the other hand, the oil made with Japanese Valerian was listed in a radical field in DAB6 (1926) in the past. This is a valuable result, proving that it was used and evaluated as an important herbal medicine from Japan and foreign countries at that time. The Japanese Valerian referred to is not grown in Japan today. Moreover, it is not possible that cultivation will be restarted through good quality revaluation. However, this fact introduces a valuable piece of history supporting the survival of Japanese Valerian and European Valerian root as a sedative in the future. PMID:25799839

  4. Personal Storytelling and Narrative as a Means for Climate Scientists to Engage and Inform Public Audiences - Illustrated by the Play '2071 - The World We'll Leave Our Grandchildren' Comissioned by the Royal Court Theatre, London and the Deutsches Schauspielhaus, Hamburg

    Rapley, C. G.

    2015-12-01

    In order to engage greater public interest in science it is necessary to move beyond the traditional academic "information deficit" mode of communication, with its emphasis on the delivery and explantion of 'facts'. This is especially the case for topics such as climate science, which have the potential to provoke strong conscious or unconscious emotional and ideological audience reactions. The use of personalised narrative and storytelling offers a means to draw in non-experts in a way that overcomes barriers of disinterest or prejudice. The talk will address the role of climate scientists in communicating within the public square, and will use the play '2071 - The World We'll Leave Our Grandchildren" as an example of how theatre can provide an effective means of communicating complex and provocative knowledge and understanding. The play was commissioned by the Royal Court Theatre, London and the Deutshes Schauspielhaus, Hamburg. It received positive reviews and sold out at the London venue.

    Deutsch's entropic uncertainty relation is examined by using two experiments in which the spin of a single spin-half particle is detected after passing through two Stern-Gerlach apparatuses in two successive times. Two experiments differ only in the angle settings of the Stern-Gerlach apparatuses. In the general case where the angles are arbitrarily arranged, Deutsch's inequality is violated.

    David Deutsch, The Fabric of Reality (London: Allen Lane, 1997), x+390 pp., ISBN 0-713-990619, hardback. David Deutsch's popular book, The Fabric of Reality, has already won acclaim as a sustained and comprehensible explanation of his own worldview, which encompasses his four main strands of quantum physics, epistemology, computation and evolution, as well as the many connections between them. Deutsch is a strong opponent of reductionism, and the latter three strands are 'high level' theories compared to quantum physics; but all four are to be regarded as fundamental because they are the theories that provide the deepest explanations. Deutsch considers that his worldview may be called the first genuine Theory of Everything; it would stand in strong contrast to the reductionist theories given that title at present. In fact he believes his approach may enable us to unify and explain not just science, but philosophy, logic, mathematics, ethics, politics and aesthetics.

  14. Methanol: the Swiss army knife of star formation. Physical properties of early stages of high mass star formation.

    NASA Astrophysics Data System (ADS)

    Leurini, Silvia; Schilke, Peter; Wyrowski, Friedrich; Menten, Karl

    Despite the major observational effort carried out in the last years by several authors (e.g. Molinari et al. 1996, Sridharan et al. 2002, Beuther et al. 2002), little is known about the initial phases of evolution of high-mass stars and their physics. A powerful diagnostic tool to investigate the early evolutionary sequence of high-mass stars is found in the analysis of their molecular spectra, which can be seen as fingerprints of a molecular cloud, as they carry the information on its chemistry, and therefore on its history, on its physical conditions and on its dynamics and kinematics. Often, symmetric rotors such as NH3 are used to probe a cloud's kinetic temperature (Walmsley & Ungerechts 1983, Danby et al. 1988), while linear molecules, e.g. CS, are used to determine its density (e.g. Snell et al. 1984, Beuther et al. 2002). However, different spatial distributions of the tracers (caused by their different chemistry) may complicate the picture, (see, e.g. Tafalla et al. 2002) as they often trace physically different and spatially non-coexisting gas components. It is thus desirable to trace all relevant physical parameters with a single molecule. Studies on slightly asymmetric rotors (H2CO: Mundy et al. 1987, Mangum & Wootten 1993; CH3OH: Leurini et al. 2004) reveal that these molecules can be used as diagnostic tools of both parameters, since slightly asymmetric molecules allow determinations of spatial density and often share a strong sensitivity to kinetic temperature with symmetric rotors. Leurini et al. 2004 have discussed the tracing properties of CH3OH, reaching the conclusion that CH3OH is indeed very useful as a prob of physical conditions in star forming regions in all mass regimes, since it has a very reach spectrum of transitions spread throughout all the centimeter, millimeter and submillimeter spectral windows. Moreover it is ubiquitously found in different regimes of star formation, from quiescent, cold (T ~ 10 K), dark clouds (Friberg et al

    NASA Astrophysics Data System (ADS)

    2013-08-01

    Using the Deutsch model of closed timelike curves, we show that a universal cloner can be constructed that when acting on a completely arbitrary qubit state, exceeds the no-cloning bound for fidelity. Since the no-cloning theorem has played a central role in the development of quantum information science, it is clear that the existence of closed timelike curves that behave according to Deutsch's model would radically change the rules for quantum information technology. Nevertheless, we show that this type of cloning does not violate no-signaling criteria.

  16. Drive decay: the cause of fast "extinction" of habits learned for brain stimulation.

    PubMed

    HOWARTH, C I; DEUTSCH, J A

    1962-07-01

    According to Deutsch's theory of intracranial self-stimulation, cessation of responding after the withdrawal of the stimulus should be a simple function of time without stimulation. To test this prediction, the lever was withdrawn from a Skinner box for varying times, then replaced and normal extinction completed. The number of extinction trials was a simple function of the time the lever was out of the box, thus confirming Deutsch's hypothesis that cessation of responding in this instance is due to a decay of a motivational excitation produced by the electrical stimulation, and not a function of the number of unreinforced trials as in normal extinction.

    The cattle fever tick, Rhipicephalus (Boophilus) microplus is one of the most significant medical veterinary pests in the world, vectoring several serious livestock diseases negatively impacting agricultural economies of tropical and subtropical countries around the world. In our study, we assembled the complete R. microplus mitochondrial genome from Illumina and Pac Bio sequencing reads obtained from the ongoing R. microplus (Deutsch strain from Texas, USA) genome sequencing project. We compared the Deutsch strain mitogenome to the mitogenome from a Brazilian R. microplus and from an Australian cattle tick that has recently been taxonomically designated as Rhipicephalus australis after previously being considered R. microplus. The sequence divergence of the Texas and Australia ticks is much higher than the divergence between the Texas and Brazil ticks. This is consistent with the idea that the Australian ticks are distinct from the R. microplus of the Americas.

    The Ferdinand Eisenberger scholarship program provides interested young urologists with the chance to undertake intensive experimental investigations for a 1-year period outside the clinical routine. Within the framework of a scientific project scholarship holders acquire competence in research and establish important contacts for themselves as well as for their institutions to scientists and research laboratories excelling in basic research. In contrast to scholarships awarded by the large funding institutions, such as the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG) and German Cancer Aid (Deutsche Krebshilfe), the Eisenberger scholarships concentrate on host laboratories in Germany. In this way the German Society of Urology (DGU) hopes to strengthen the research infrastructure of urology in Germany with effective regional and national networks.

The result is a closely coordinated international program of Space Life Sciences which will enable optimal utilization of space flight opportunities.

  11. Adaptive finite-element ballooning analysis of bipolar ionized fields

    SciTech Connect

    Al-Hamouz, Z.M.

    1995-12-31

    This paper presents an adaptive finite-element iterative method for the analysis of the ionized field around high-voltage bipolar direct-current (HVDC) transmission line conductors without resort to Deutsch`s assumption. A new iterative finite-element ballooning technique is proposed to solve Poisson`s equation wherein the commonly used artificial boundary around the transmission line conductors is simulated at infinity. Unlike all attempts reported in the literature for the solution of ionized field, the constancy of the conductors` surface field at the corona onset value is directly implemented in the finite-element formulation. In order to investigate the effectiveness of the proposed method, a laboratory model was built. It has been found that the calculated V-I characteristics and the ground-plane current density agreed well with those measured experimentally. The simplicity in computer programming in addition to the low number of iterations required to achieve convergence characterize this method of analysis.

    Abdel-Salam, M.; Al-Hamouz, Z.

    1995-05-01

    This paper describes a new iterative method for the analysis of the bipolar ionized field in HVDC transmission lines without resorting to Deutsch`s assumption. The finite-element technique (FET) is used to solve Poisson`s equation where the constancy of the conductors` surface field at the corona inception value is directly implemented in the finite-element formulation. The proposed method has been tested on laboratory and full-scale models. The calculated V-I characteristics agreed well with those calculated and measured previously. The dependence of the corona current as well as its monopolar and bipolar components on the conductor height is discussed. The simplicity in computer programming in addition to the low number of iterations required to achieve convergence characterize the proposed method of analysis.

    For the care of the elderly, specific geriatric care facilities in hospitals and specialized rehabilitation centers have been established in the last 20 years throughout Germany. In addition, trauma surgery departments in hospitals and clinics also provide comprehensive care for trauma patients. The present requirements catalog was developed with the aim to ensure the standardization and quality assurance of these care facilities. Thus, the structural basics and, in particular, the structured cooperation between geriatrics and trauma surgery are described and defined in terms of structure, process, and outcome quality. The Bundesverband Geriatrie, the Deutsche Gesellschaft für Geriatrie, and the Deutsche Gesellschaft für Gerontologie und Geriatrie offer documentation for external and internal use and evaluation of the structures and processes for certification of geriatric trauma centers. Prerequisite for certification is to meet the technical requirements defined in the requirements catalogue or documents derived from it, and proof of a quality management system according to ISO 9001.

    NASA Astrophysics Data System (ADS)

    Baker, David J.

    The decision-theoretic account of probability in the Everett or many-worlds interpretation, advanced by David Deutsch and David Wallace, is shown to be circular. Talk of probability in Everett presumes the existence of a preferred basis to identify measurement outcomes for the probabilities to range over. But the existence of a preferred basis can only be established by the process of decoherence, which is itself probabilistic.

    Kötter, Thomas; Voltmer, Edgar

    2013-01-01

    Zielsetzung: Medizinstudierende sind spezifischen Stressoren ausgesetzt. Als Folge der Stressbelastung kommt es bei Medizinstudierenden im Vergleich zu gleichaltrigen Berufstätigen häufiger zu Ängsten, Depressionen und Burn-out. Vitaliano et al. haben bereits 1984 ein 13 Items umfassendes Instrument zur Messung der spezifischen Stressbelastung von Medizinstudierenden, das „Perceived Medical School Stress Instrument“ (PMSS), vorgestellt. Es wurde seitdem im englischsprachigen Bereich breit eingesetzt und validiert. Bislang liegt jedoch keine deutschsprachige Version des Instrumentes vor. Ziel des Projektes war die Übersetzung des PMSS in die deutsche Sprache, um es im Rahmen von Studien im deutschsprachigen Raum einzusetzen.Methodik: Die englischsprachigen Items des PMSS wurden von drei Untersuchern in die deutsche Sprache übersetzt. Die Versionen wurden synoptisch gegenübergestellt und auf dieser Basis wurde für jedes Item eine deutschsprachige Version formuliert. Diese Versionen wurden von Muttersprachlerinnen in die englische Sprache zurückübersetzt. Auf der Basis dieser Rückübersetzungen, eines kognitiven Debriefings an 19 deutschen Medizinstudierenden und einer testtheoretischen Evaluation an 169 deutschen Medizinstudierenden wurden dann die endgültigen deutschsprachigen Formulierungen festgelegt. Ergebnisse: Das PMSS konnte ohne größere Schwierigkeiten in die deutsche Sprache übersetzt werden. Sowohl zwischen den Übersetzungen in die deutsche Sprache als auch zwischen beiden Rückübersetzungen waren die Übereinstimmungen groß. Bei Diskrepanzen erfolgte die Einigung schnell und unkompliziert. Der Einsatz der deutschsprachigen Version erbrachte einen guten Wert für die Reliabilität (Cronbachs Alpha 0,81).Schlussfolgerung: Es steht nun auch für deutschsprachigen Raum ein spezifisches Instrument zur Messung der Stressbelastung von Medizinstudierenden zur Verfügung.

    1983-01-01

    Discovery of unlocked contacts in Deutsch Block terminal junctions in Solid Rocket Booster flight hardware prompted an investigation into pull test techniques to help insure against possible failures. Internal frictional forces between socket and pin and between wire and grommet were examined. Pull test force must be greater than internal friction yet less than the crimp strength of the pin or socket. For this reason, a 100 percent accurate test is impossible. Test tools were evaluated. Available tools are adequate for pull testing.

  9. Multifractal nature of stock exchange prices

    NASA Astrophysics Data System (ADS)

    Ausloos, M.; Ivanova, K.

    2002-08-01

    The multifractal structure of the temporal dependence of the Deutsche Aktienindex (DAX) is analyzed. The qth order moments of the structure functions and the singular measures are calculated. The generalized Hurst exponent H( q) and the h( γ( q)) curve indicate a hierarchy of power law exponents. This approach leads to characterizing the nonstationarity and intermittency pertinent to such financial signals, indicating differences with turbulence data. A list of results on turbulence and financial markets is presented for asserting the analogy.

    We report on the identification of the optical counterpart to Star1, the exotic object serendipitously discovered by Deutsch et al. in the core of the Galactic globular cluster NGC 6624. Star1 has been classified by Deutsch et al. as either a quiescent cataclysmic variable or a low-mass X-ray binary. Deutsch et al. proposed StarA as a possible optical counterpart to this object. We used high-resolution images obtained with the Hubble Space Telescope to perform a variability analysis of the stars close to the nominal position of Star1. While no variability was detected for StarA, we found another star, referred to here as COM{sub S}tar1, showing a clear sinusoidal light modulation with amplitude Δm {sub F435W} ∼ 0.7 mag and an orbital period of P {sub orb} ∼ 98 minutes. The shape of the light curve is likely caused by strong irradiation by the primary heating of one hemisphere of the companion, thus suggesting a quite hot primary.

  11. Revisiting Consistency Conditions for Quantum States of Systems on Closed Timelike Curves: An Epistemic Perspective

    NASA Astrophysics Data System (ADS)

    Wallman, Joel J.; Bartlett, Stephen D.

    2012-05-01

    There has been considerable recent interest in the consequences of closed timelike curves (CTCs) for the dynamics of quantum mechanical systems. A vast majority of research into this area makes use of the dynamical equations developed by Deutsch, which were developed from a consistency condition that assumes that mixed quantum states uniquely describe the physical state of a system. We criticize this choice of consistency condition from an epistemic perspective, i.e., a perspective in which the quantum state represents a state of knowledge about a system. We demonstrate that directly applying Deutsch's condition when mixed states are treated as representing an observer's knowledge of a system can conceal time travel paradoxes from the observer, rather than resolving them. To shed further light on the appropriate dynamics for quantum systems traversing CTCs, we make use of a toy epistemic theory with a strictly classical ontology due to Spekkens and show that, in contrast to the results of Deutsch, many of the traditional paradoxical effects of time travel are present.

  12. Decision theory and information propagation in quantum physics

    NASA Astrophysics Data System (ADS)

    Forrester, Alan

    In recent papers, Zurek [(2005). Probabilities from entanglement, Born's rule p k =| ψ k | 2 from entanglement. Physical Review A, 71, 052105] has objected to the decision-theoretic approach of Deutsch [(1999) Quantum theory of probability and decisions. Proceedings of the Royal Society of London A, 455, 3129-3137] and Wallace [(2003). Everettian rationality: defending Deutsch's approach to probability in the Everett interpretation. Studies in History and Philosophy of Modern Physics, 34, 415-438] to deriving the Born rule for quantum probabilities on the grounds that it courts circularity. Deutsch and Wallace assume that the many worlds theory is true and that decoherence gives rise to a preferred basis. However, decoherence arguments use the reduced density matrix, which relies upon the partial trace and hence upon the Born rule for its validity. Using the Heisenberg picture and quantum Darwinism-the notion that classical information is quantum information that can proliferate in the environment pioneered in Ollivier et al. [(2004). Objective properties from subjective quantum states: Environment as a witness. Physical Review Letters, 93, 220401 and (2005). Environment as a witness: Selective proliferation of information and emergence of objectivity in a quantum universe. Physical Review A, 72, 042113]-I show that measurement interactions between two systems only create correlations between a specific set of commuting observables of system 1 and a specific set of commuting observables of system 2. This argument picks out a unique basis in which information flows in the correlations between those sets of commuting observables. I then derive the Born rule for both pure and mixed states and answer some other criticisms of the decision theoretic approach to quantum probability.

  13. The DHL EuroCup: shots on goal.

    PubMed

    Hemp, Paul

    2003-11-01

    Deutsche Post World Net, the German postal monopoly, faced significant challenges as it began the process of integrating three businesses: Deutsche Post Euro Express, its own ground-based parcel delivery service, and two companies it had acquired-DHL, the worldwide express delivery service, and Danzas, a worldwide air and ocean freight company. The cultural differences alone were imposing. For example, DHL was a privately held, entrepreneurial company in which most managers had international experience; Deutsche Post was until recently a state-owned monopoly in which few managers had worked outside their home country. Enter EuroCup. For 20 years, DHL employees had held a soccer tournament to strengthen company culture across national boundaries. Canceled the previous year due to budget constraints, the EuroCup tournament was revived in 2003-in part to help with the postmerger integration. But did the event really help? HBR senior editor Paul Hemp attended EuroCup 2003, joining nearly 2,500 DHL employees--about 600 of them players, the rest cheerleaders and other supporters--in the small Belgian town of Lommel. He set out to answer a number of questions relevant to any company staging an ambitious off-site intended to encourage teamwork and boost morale. How does a company determine whether such a large-scale event, even one that generates goodwill, is worth the investment? Does the team building extend to those back home who don't get to attend? Can intense competition between teams begin to overshadow the spirit of cooperation that such an event is meant to engender? In short, can a soccer tournament help a company achieve its corporate goal of creating a strong common culture?

    Irbäck, Anders; Peterson, Carsten; Potthast, Frank; Sandelin, Erik

    1998-11-01

    A method for sequence optimization in protein models is presented. The approach, which has inherited its basic philosophy from recent work by Deutsch and Kurosky [Phys. Rev. Lett. 76, 323 (1996)] by maximizing conditional probabilities rather than minimizing energy functions, is based upon a different and very efficient multisequence Monte Carlo scheme. By construction, the method ensures that the designed sequences represent good folders thermodynamically. A bootstrap procedure for the sequence space search is devised making very large chains feasible. The algorithm is successfully explored on the two-dimensional HP model [K. F. Lau and K. A. Dill, Macromolecules 32, 3986 (1989)] with chain lengths N=16, 18, and 32.

    2016-03-01

    Vacuum birefringence is another lingering challenge which will soon become accessible to experimental verification. The effect was first calculated by Euler and Heisenberg in 1936 and is these days described as a one-loop correction to the differential index of refraction between light which is polarized parallel and perpendicular to an external magnetic field. Our plan is to realize (and slightly modify) an idea which was originally published by Hall, Ye, and Ma using advanced LIGO and LISA technology and the infrastructure of the ALPS light-shining-through-walls experiment following the ALPS IIc science run. This work is supported by the Deutsche Forschungsgemeinschaft and the Heising-Simons Foundation.

  1. Everettian quantum mechanics and physical probability: Against the principle of "State Supervenience"

    NASA Astrophysics Data System (ADS)

    Jansson, Lina

    2016-02-01

    Everettian quantum mechanics faces the challenge of how to make sense of probability and probabilistic reasoning in a setting where there is typically no unique outcome of measurements. Wallace has built on a proof by Deutsch to argue that a notion of probability can be recovered in the many worlds setting. In particular, Wallace argues that a rational agent has to assign probabilities in accordance with the Born rule. This argument relies on a rationality constraint that Wallace calls state supervenience. I argue that state supervenience is not defensible as a rationality constraint for Everettian agents unless we already invoke probabilistic notions.

    The Deutsche Gesellschaft für Urologie (German Urological Association), established in 1907, was a German-Austrian medical society in which Jewish physicians held important positions. When the Nazis seized power in 1933, the Austrian Hans Rubritius was president of the society. The non-German presidency and the exclusion of Jewish colleagues from the professional society and medical practice led to a halt of the society's activities. At the same time in the mid 1930s, German urologists founded the Gesellschaft Reichsdeutscher Urologen (Association of Reichs-German Urologists) whose members aligned themselves with Nazi health policies and in turn received professional and personal benefits.

    Visitations (audits) are considered an instrument of external quality assurance by which the structural and organizational set-up of health facilities can be assessed on site by external experts. The Deutsche Rentenversicherung Bund (including the former Bundesversicherungsanstalt für Angestellte, BfA, the statutory pension insurance agency for white collar employees) is the largest body responsible for rehabilitation in Germany, and it regularly carries out visitations in the approximately 650 rehab centres it sends its patients to. The project presented in this article aimed at developing a manual with detailed descriptions of the procedures and criteria of the assessment, as well as at checking the inter-rater-reliability of the assessment. The manual was developed in cooperation with experts of the Deutsche Rentenversicherung Bund. It contains a description of the areas to be assessed during a visitation as well as leading questions and criteria for the evaluation of single features. The manual was examined in "test visitations" in 10 centres, each of which was visited by three visitation teams (1 medical and 1 administrative expert) simultaneously. When the resulting 30 assessments were compared, the criterion "overall quality of the centre" (which was assessed on a 10-point scale) showed precise agreement in 47 %, and a deviation by 1 point in 33 % of the cases. Single features assessed on a three-point scale (no improvement needed/improvement recommended/immediate improvement obligatory) resulted in precise agreement in between 80 % ("medical and therapeutic processes") and 86 % ("structural features") of the cases. Two-point scales (condition fulfilled or not fulfilled) showed an agreement between 89 % ("internal quality management") and 97 % ("single structural features"). In order to maintain and further develop this good inter-rater-reliability, the visitors of Deutsche Rentenversicherung Bund are continually trained in applying the visitation manual

    The oxidation-induced valence change of Yb leads to a single 4f hole in the ground state. The creation of the 4f13 configuration which does not exist for any pure rare-earth metal makes it possible to analyze the 4d-->4f Fano resonance for a simple system experimentally as well as theoretically. Calculated Fano profiles for the 4f12 final-state multiplets are in good agreement with photoemission measurements taken with the FLIPPER monochromator at Hamburger Synchrotron-strahlungslabor, Deutsches Elektronen-Synchrotron, using synchrotron radiation from the storage ring DORIS.

    This paper presents two different approaches to detect and correct phase errors appearing in interferometric airborne SAR sensors due to the lack of precision in the navigation system. The first one is intended for interferometric pairs with high coherence, and the second one for low coherent ones. Both techniques are based on a multisquint processing approach, i.e., by processing the same image pairs with different squint angles we can combine the information of different interferograms to obtain the desired phase correction. Airborne single- and repeat-pass interferometric data from the Deutsches Zentrum fur Luft- und Raumfahrt (DLR) Experimental airborne SAR is used to validate the method.

    Many results have been recently obtained regarding the power of hypothetical closed timelike curves (CTCs) in quantum computation. Here we show that the one-way model of measurement-based quantum computation encompasses in a natural way the CTC model proposed by Bennett, Schumacher, and Svetlichny. We identify a class of CTCs in this model that can be simulated deterministically and point to a fundamental limitation of Deutsch's CTC model which leads to predictions conflicting with those of the one-way model.

    2003-10-31

    For a practical quantum computer to operate, it is essential to properly manage decoherence. One important technique for doing this is the use of "decoherence-free subspaces" (DFSs), which have recently been demonstrated. Here we present the first use of DFSs to improve the performance of a quantum algorithm. An optical implementation of the Deutsch-Jozsa algorithm can be made insensitive to a particular class of phase noise by encoding information in the appropriate subspaces; we observe a reduction of the error rate from 35% to 7%, essentially its value in the absence of noise.

    We show that deterministic quantum computing with one qubit (DQC1) can be experimentally implemented with a spatial light modulator, using the polarization and the transverse spatial degrees of freedom of light. The scheme allows the computation of the trace of a high-dimension matrix, being limited by the resolution of the modulator panel and the technical imperfections. In order to illustrate the method, we compute the normalized trace of unitary matrices and implement the Deutsch-Jozsa algorithm. The largest matrix that can be manipulated with our setup is 1080 ×1920 , which is able to represent a system with approximately 21 qubits.

    Understanding microbial diversity in spacecraft assembly clean rooms is of major interest with respect to planetary protection considerations. A coordinated screening of different clean rooms in Europe and South America by three German institutes [Deutsches Zentrum für Luft- und Raumfahrt (DLR), Leibniz-Institut DSMZ-Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (DSMZ), and the Institute of Microbiology and Archaea Center, University of Regensburg] took place during the assembly, test, and launch operations of the Herschel spacecraft in 2006-2009. Through this campaign, we retrieved critical information regarding the microbiome within these clean rooms and on the Herschel spacecraft, which served as a model for upcoming ESA mission preparations. This "lessons learned" document summarizes and discusses the data we obtained during this sampling campaign. Additionally, we have taken the opportunity to create a database that includes all 16S rRNA gene sequences ever retrieved from molecular and cultivable diversity studies of spacecraft assembly clean rooms to compare the microbiomes of US, European, and South American facilities.

    The long-range objective of this research program is the development of more efficacious technetium-99m radiopharmaceuticals for use as imaging agents in diagnostic nuclear medicine. We seek to isolate and develop distinct site imaging agents, each of which has properties optimized to provide diagnostic information concerning a given pathological condition. The specific objectives during the period (9/1/89 to 8/31/92) include: (1) Development of strategies for improving yields of specific Tc-diphosphonate complexes with optimum imaging properties; (2) Development of electrodes for rapid in situ electrochemical generation of skeletal imaging agents; (3) Development of electrochemical sensors for {Tc} and Re imaging agents; (4) Characterization of stable {Tc}- and Re-diphosphonate complexes obtainable in high yield by structural studies with techniques such as NMR, EXAFS, and Raman spectroscopy; (5) Development of improved separation techniques for the characterization of diphosphonate skeletal imaging agents; (6) Evaluation of the effect of the biological milieu on {Tc}-diphosphonate complexes; and (7) Electrochemical studies of technetium and rhenium complexes synthesized by Professor Deutsch`s research group for heart and brain imaging.

    The simplest tricyclic aromatic nitrogen heterocyclic molecules 5,6 benzoquinoline and 7,8 benzoquinoline are possible candidates for detection of aromatic systems in the interstellar medium. Therefore the pure rotational spectra have been recorded using frequency-scanned Stark modulated, jet-cooled millimetre wave absorption spectroscopy (48-87 GHz) and Fourier Transform Microwave (FT MW) spectroscopy (2-26 GHz) of a supersonic rotationally cold molecular jet. Guided by ab initio molecular orbital predictions, spectral analysis of mm wave spectra, and higher resolution FT MW spectroscopy provided accurate rotational and centrifugal distortion constants together with 14N nuclear quadrupole coupling constants for both species. The determined inertial defects, along with those of similar species are used to develop an empirical formula for calculation of inertial defects of aromatic ring systems. The predictive ability of the formula is shown to be excellent for planar species with a number of pronounced out of plane vibrations. The resultant constants are of sufficient accuracy to be used in potential astrophysical searches. We gratefully acknowledge support from the Deutsche Forschungsgemeinschaft, the Deutsche Akademische Austauschdienst, as well as the Land Niedersachsen (J.-U.G). DMcN also thanks the Royal Society of Chemistry for their generous travel support.

  8. Pitch jnd and the tritone paradox: The linguistic nexus

    2002-11-01

    Previous research has shown a connection between absolute pitch (the ability to name a specific pitch in the absence of any reference) and native competence in a tone language (Deutsch, 1990). In tone languages, tone is one of the features which determines the lexical meaning of a word. This study investigates the relationship between native competence in a tone language and the just noticeable difference of pitch. Furthermore, the tritone paradox studies have shown that subjects hear two tritones (with bell-shaped spectral envelopes) as either ascending or descending depending on their linguistic backgrounds (Deutsch, 1987). It is hypothesized that the native speakers of tone languages have a higher JND for pitch, and hear the two tones of the tritone paradox as ascending, whereas, native speakers of nontone languages hear them as descending. This study will indicate the importance of early musical training for the development of acute tone sensitivity. It will also underline the importance of language and culture in the way it shapes our musical understanding. The significance of this study will be in the areas of music education and pedagogy.

    West Indian manatees (Trichechus manatus) are listed as vulnerable (IUCN Red List, 7 March 2009; Deutsch et al., 2008), with the subspecies Trichechus manatus latirostris and T. m. manatus (Florida and Antillean, respectively) considered endangered (IUCN Red List, 21 January 2011; Deutsch, 2008; Self-Sullivan & Mignucci-Giannoni, 2008). Manatees are not native to The Bahamas; however, sightings have been recorded periodically since 1904, with an increase in sightings documented in the 1990s (Lefebvre et al., 2001). In the area of Bimini, The Bahamas, the first recorded manatee sighting was in 1904 of a single individual that was apparently killed (Allen, 1942). The second was not until 1996, which was poorly documented. The small adult remained for approximately 6 wks before disappearing (Lefebvre et al., 2001). In 1998, a third sighting was reported off Bimini of a single individual. Although the animal was seen for several weeks and was relatively habituated to human presence (Al Sweeting, Jr., pers. comm., 28 November 2008), no data were collected on this individual nor any photographs suitable for identification purposes.

    A total of 218 breast cancer centers, with 274 operating sites, have been certified since 2003 in accordance with the criteria set out by the German Cancer Society (Deutsche Krebsgesellschaft) and the German Society for Breast Diseases (Deutsche Gesellschaft für Senologie). Most of these centers are located in Germany, but centers in Austria, Switzerland, and Italy have also been certified. This paper presents the results for quality indicators (QIs) from 2009 to 2012, based on data from 195,342 primary breast cancer patients, in order to illustrate the development and progress of these centers. Descriptive results on interdisciplinary collaboration (6 QIs), guideline adherence (15 QIs), and specialist expertise (7 QIs) are reported over time. Fulfillment of the certification requirements was high and remained relatively stable over time, with the extent of variation between sites declining. Sites that do not reach the target values are asked to comment on the discrepancies, and their comments, as well as the QI results, are used by centers and auditors during an on-site auditing process and to constantly revise the QIs set out by the guideline and the certification commission.

    In order to address the European Directive 2004/23 on human tissues and cells, the authorization obligation for tissue and blood stem cell preparations was introduced (§ 21a AMG) in the year 2007 in the German medicinal products act. Stem cell transplantation for hematopoietic reconstitution has been in use for decades and is well established for the treatment of many malignancies. The manufacture of stem cell preparations varies, but in terms of hematopoietic reconstitution, different products are intended for the same indication. Taking these aspects into account, it was considered inappropriate that every single applicant should provide their own documentation, including an expert report on clinical and nonclinical data. Consequently, the idea came up to create a central expert report, to which all applicants could refer and would include relevant clinical and nonclinical data according to current knowledge. A central expert report was therefore generated, called the "Gemeinsame Stellungnahme der Fachgesellschaften Deutsche Gesellschaft für Transfusionsmedizin und Immunhämatologie (DGTI), Deutsche Gesellschaft für Hämatologie und Onkologie (DGH) und Gesellschaft für Pädiatrische Onkologie und Hämatologie (GPOH)". Applicants are allowed to refer to this central expert report provided their stem cell product is comparable with the cell preparations included in the report. In order to represent current knowledge, the content of the central expert report was already reworked once, but should be updated regularly.

    At July 2, 1969, the Deutsche Bundestag has invited the Bundesregierung to submit a new and comprehensive law for animal welfare. After having removed difficulties with the constitution by completion of the constitution (at 18. March 1971) with animal welfare an outline of a new animal welfare law was presented to the Deutsche Bundestag in September 1971, and at July 24., 1972, the new law came into force. The leading idea of the former right, to protect the animal against pain and suffering has been promoted and extended to the protection of life of the animal simply. The animals protection-position is only allowed to restrict, if there is a reasonable proof coming out from very important common interests. The law prescribes for those, who are holders of animal more duties than in former time; species and needs of animal are to be laid down. To avoid the excavation of prohibition of experiments with animal by many exceptions the principle is introduced to approve respectively to notify experiments with animals before beginning. The amendment of the animal welfare law of August 12, 1986, concerns especially the regulations about experiments with animals, among many other new instructions a commission for ethics has been introduced. New is also, that the importance of animals as fellow-creature is mentioned in the law. The social process of learning in animal welfare is not yet finished, the new animal welfare law has given a contribution for arising a responsibility for ethics in a capable of bearing.

    The German Society of Anaesthesiology and Intensive Care Medicine (Deutsche Gesellschaft für Anästhesiologie und Intensivmedizin, DGAI) established an expert panel to develop preliminary recommendations for the application of peripheral nerve blocks on the upper extremity. The present recommendations state in different variations how ultrasound and/or electrical nerve stimulation guided nerve blocks should be performed. The description of each procedure is rather a recommendation than a guideline. The anaesthesiologist should select the variation of block which provides the highest grade of safety according to his individual opportunities. The first section comprises recommendations regarding dosages of local anaesthetics, general indications and contraindications for peripheral nerve blocks and informations about complications. In the following sections most common blocks techniques on the upper extremity are described. PMID:26408023

    The Electric Fuel Limited (EFL) refuelable zinc-air battery system is currently being tested in a number of electric vehicle demonstration projects, the largest of which is a field test of zinc-air postal vans sponsored chiefly by Deutsche Post AG (the German Post Office). The zinc-air battery is not recharged electrically, but rather is refueled through a series of mechanical and electrochemical steps that will require a special infrastructure in commercial application. As part of the German Post Office field test program, Electric Fuel designed and constructed a pilot zinc anode regeneration plant in Bremen, Germany. This plant is capable of servicing up to 100 commercial vans per week, which is adequate for the field test vehicle fleet. This paper will describe the design and operation of each of the areas and devices within the plant.

    In a joint project of Deutsche Aerospace, Boehringer Mannheim and the University of Potsdam portable devices for the detection of illegal drugs, based on biosensor technology, are being developed. The concept enrichment of the drug from the gas phase and detection by immunological means. This publication covers the description of our objectives, preparatory work and results concerning enrichment of drugs from the gas phase. Vapor pressures of cocaine and cannabinoids have been determined. A test gas generator has been constructed which allows for reproducible preparation of cocaine concentrations between 2 ng/l and 2 pg/l. Coupling of a thermodesorption unit with GC/MS has been established for reference analysis. As another analytical tool, an ELISA with a lower detection limit of about 0,5 pg cocaine/assay has been developed. Applying fleece-type adsorbers, enrichment factors for cocaine in the range of 105 have been realized. No significant interference was found with potentially disturbing substances.

  17. Supply Chain Engineering and the Use of a Supporting Knowledge Management Application

    Laakmann, Frank

    The future competition in markets will happen between logistics networks and no longer between enterprises. A new approach for supporting the engineering of logistics networks is developed by this research as a part of the Collaborative Research Centre (SFB) 559: "Modeling of Large Networks in Logistics" at the University of Dortmund together with the Fraunhofer-Institute of Material Flow and Logistics founded by Deutsche Forschungsgemeinschaft (DFG). Based on a reference model for logistics processes, the process chain model, a guideline for logistics engineers is developed to manage the different types of design tasks of logistics networks. The technical background of this solution is a collaborative knowledge management application. This paper will introduce how new Internet-based technologies support supply chain design projects.

    Wells on the first of 2 small concrete platforms designed specifically for the fragile but harsh environment of the Baltic Sea will produce the first oil from that offshore area by late 1984. The consortium of Deutsche Texaco AG and Wintershall AG awarded contracts late last year for the platforms and drilling equipment needed to develop the Schwedeneck-See field in Kiel Bay, off the northern coast of West Germany. Severe winter weather in the area dictated the use of concrete platforms rather than conventional 6-pile steel structures. Ice forces, generated by high winds and moderate waves, demanded heavy-duty structures in spite of the shallow water. A complicating factor in the field development plan is the presence of a German Navy submarine practice area which influenced location of one of the platforms. This means that all wells will be directionally drilled, and the reach will be greater than under more favorable conditions.

    Deutsche Texaco A.G. will be the first operator on behalf of itself and Wintershall A.G. to produce oil from the German sector of the North Sea, with its first oil due end of 1986 from the Mittelplate pilot project. Texaco also was the first to produce oil from the Baltic Sea when Schwedeneck-See field, near Kiel Bay, went on production last year. The pilot project at Mittelplate will yield more data on the reservoirs confirmed by four wells drilled in 1980-1981, and will be carried out in spite of adverse operating conditions. Problems facing Texaco engineers in their project design include: A mud-flat location dry at low tide but submerged at high tide. Efforts to convince environmental groups that no permanent harm would result from company activities. Shipment of low-gravity crude containing asphaltenes. Logistics of transporting equipment and supplies on a schedule dictated by tides.

    On average, lacto-ovo-vegetarians develop cancer less often than their meat-eating fellows. A particularly clear correlation exists between vegetable consumption and the reduction of the risk of developing cancer of the gastrointestinal tract or lung cancer. The factors responsible for the anticarcinogenic effects are not vitamins, minerals and ballast (fiber) alone, but also include in particular the secondary plant substances, whose numbers run into thousands. These substances act in a variety of different ways--for example carotinoids and flavonoids inhibit carcinogen-activating enzymes, phyto-estrogens and indoles have a modulating effect on the hormone metabolism, while saponins or sulfides stimulate the body's natural killer cells. Against this background, the German Society for Nutrition (Deutsche Gesellschaft für Ernährung) recommends the daily consumption of 375 grams of vegetables and about 250 to 300 grams of fruit.

    The first clinical experiences with extracorporeal shockwave lithotripsy (ESWL)--the method of choice in noninvasive treatment of renal calculi--were so encouraging that more ESWL units are now being installed and a still larger number can be predicted. A cost-efficiency analysis shows that, in spite of high investment costs, a net saving of about DM 4,599 (deutsche marks) can be figured for each 'ESWL patient' compared to the expenses of an open operation. This benefit is due to the reduction of disability time, hospital stay and dialysis cases. For the management of an ESWL unit a trained team of urologists and anesthesiologists, as well as a clinic with an 'operative background' is necessary.

  11. Theory of gel electrophoresis in high fields: Evolution of a population of hernias

    NASA Astrophysics Data System (ADS)

    Long, Didier; Viovy, Jean-Louis

    1997-02-01

    We consider long polyelectrolytes that are initially at rest in a gel and suddenly submitted to a strong electric field. The evolution of the conformation regime is described up to the final disengagement from the initial tube. Just after the field has been applied, the chain adopts a comb-like conformation with several “hernias”, which evolve in competition with each other. As long as the conformation has many hernias, the distribution of their size follows a self-similar law, first described by Deutsch. The number of hernias decreases, and ultimately the chain disengages from its initial tube. Various predictions for the conformation of the chain in this last stage and for time constants are proposed. In particular, the disengagement times are found to follow a self-similar law in the size of the chains.

    Several species of bees in South America possess structures to store and transport floral oils. By using closely spaced hairs at their back legs, the so called scopa, these bees can absorb and release oil droplets without loss. The high efficiency of this process is a matter of ongoing research. Basing on recent x-ray microtomography scans from the scopa of these bees at the Institute of Textile Technology and Process Engineering Denkendorf, we build a three-dimensional computer model. Using NaSt3DGPF, a two-phase flow solver developed at the Institute for Numerical Simulation of the University of Bonn, we perform massively parallel flow simulations with the complex micro-CT data. In this talk, we discuss the results of our simulations and the transfer of the x-ray measurement into a computer model. This research was funded under GR 1144/18-1 by the Deutsche Forschungsgemeinschaft (DFG).

    In order to adequately perform its many diverse tasks as a scholars' society and as the German National Academy of Sciences, the Deutsche Akademie der Naturforscher Leopoldina needs to view itself in a historical context. This can only happen as part of a culture of remembrance which fosters the memory of the Leopoldina's past and subjects this to a critical analysis in the context of the history of science and academies. The newly founded Leopoldina Study Center for the History of Science and Science Academies is to be a forum that pursues established forms of historical research at the Leopoldina, organizes new scientific projects, and presents its findings to the public. The aim is to involve as many Leopoldina members as possible from all of its disciplines, as well as to collaborate with national and international partners.

    Four papers were presented by Group X-6 on April 22, 1980, at the Oak Ridge Radiation Shielding Information Center (RSIC) Seminar-Workshop on Theory and Applications of Monte Carlo Methods. These papers are combined into one report for convenience and because they are related to each other. The first paper (by Thompson and Cashwell) is a general survey about X-6 and MCNP and is an introduction to the other three papers. It can also serve as a resume of X-6. The second paper (by Godfrey) explains some of the details of geometry specification in MCNP. The third paper (by Cashwell and Schrandt) illustrates calculating flux at a point with MCNP; in particular, the once-more-collided flux estimator is demonstrated. Finally, the fourth paper (by Thompson, Deutsch, and Booth) is a tutorial on some variance-reduction techniques. It should be required for a fledging Monte Carlo practitioner.

    In 1994 and 1998 reports on staffing levels in medical radiation physics for radiation therapy were published by the "Deutsche Gesellschaft für Medizinische Physik" (DGMP, German Society for Medical Physics). Because of the technical and methodological progress, changes in recommended qualifications of staff and new governmental regulations, it was necessary to establish new staffing levels. The data were derived from a new survey in clinics. Some of the previously established results from the old reports were adapted to the new conditions by conversion.The staffing requirements were normalized to main components as in the earlier reports resulting in a simple method for calculation of staffing levels. The results were compared with the requirements in the "Richtlinie Strahlenschutz in der Medizin" (guidelines on radiation protection in medicine) and showed satisfactory agreement.

    Classical MD data on the charge-charge dynamic structure factor of two-component plasmas (TCP) modeled in Phys. Rev. A 23, 2041 (1981) are analyzed using the sum rules and other exact relations. The convergent power moments of the imaginary part of the model system dielectric function are expressed in terms of its partial static structure factors, which are computed by the method of hypernetted chains using the Deutsch effective potential. High-frequency asymptotic behavior of the dielectric function is specified to include the effects of inverse bremsstrahlung. The agreement with the MD data is improved, and important statistical characteristics of the model TCP, such as the probability to find both electron and ion at one point, are determined.

    The Seismic reflection profiles of DEKORP (DEutsches KOntinentales ReflexionsSeismisches Programm) in the Federal Republic of Germany to date have been limited to areas of the Variscan orogeny. Nevertheless, the character of their reflections differs considerably and may be correlated to certain Variscan and post-Variscan developments. Lower crust lamellae develop in areas of high heat flow, mostly associated with post-Variscan extensional processes; "crocodile" and nappe tectonics are best preserved in the cores and at the flanks of older massifs which were incorporated into the Variscan orogeny. So far poor reflectivity has been observed only in the area of the London-Brabant Massif which was not involved in any of the Phanerozoic orogenies.

    Networks of polymerizing actin filaments are known to be capable to self-organize into a variety of structures. For example, spontaneous actin polymerization waves have been observed in living cells in a number of circumstances, notably, in crawling neutrophils and slime molds. During later stages of cell division, they can also spontaneously form a contractile ring that will eventually cleave the cell into two daughter cells. We present a framework for describing networks of polymerizing actin filaments, where assembly is regulated by various proteins. It can also include the effects of molecular motors. We show that the molecular processes driven by these proteins can generate various structures that have been observed in contractile rings of fission yeast and mammalian cells. We discuss a possible functional role of each of these patterns. The work was supported by Agence Nationale de la Recherche, France, (ANR-10-LABX-0030-INRT) and by Deutsche Forschungsgemeinschaft through SFB1027.

    Electronic components during High Energy Physics experiments are exposed to high level of radiation. Radiation environment causes many problems to electronic devices. The goal of several experiments done at DESY (Deutsches Elektronen Synchrotron, Hamburg) was to investigate nature of irradiation effects, caused damages and possible techniques of mitigation. One of aspects of experiments is radiation measurements. The propositions of building radiation monitoring system, using different semiconductor components, are presented. Second aspect is radiation tolerance. Different electronic devices were tested: FPGA chips, CCD sensors, bubble dosimeters and LED diodes. Components were irradiated in TESLA Test Facility 2 tunnel and in laboratory using 241Am/Be neutron source. The results of experiments are included and discussed.

Klystron linearization is essential for the realization of ILC, since it is required to operate the klystrons 7% in power below their saturation. The work presented was performed in international collaborations at the Fermi National Accelerator Laboratory (FNAL), USA and the Deutsches Elektronen Synchrotron (DESY), Germany. With the newly developed algorithms, the generation of correction factors on the FPGA was improved compared to past algorithms, avoiding quantization and decreasing memory requirements. At FNAL, three algorithms were tested at the Advanced Superconducting Test Accelerator (ASTA), demonstrating a successfulmore » implementation for one algorithm and a proof of principle for two algorithms.

    Optically trapped ensembles are of crucial importance for frequency measurements and quantum memories but generally suffer from strong dephasing due to inhomogeneous density and light shifts. We demonstrate a drastic increase of the coherence time to 21 s on the magnetic field insensitive clock transition of {sup 87}Rb by applying the recently discovered spin self-rephasing [C. Deutsch et al., Phys. Rev. Lett. 105, 020401 (2010)]. This result confirms the general nature of this new mechanism and thus shows its applicability in atom clocks and quantum memories. A systematic investigation of all relevant frequency shifts and noise contributions yields a stability of 2.4x10{sup -11{tau}-1/2}, where {tau} is the integration time in seconds. Based on a set of technical improvements, the presented frequency standard is predicted to rival the stability of microwave fountain clocks in a potentially much more compact setup.

Spin-bus clusters are considered as local processing units and may be interconnected with other spin-bus clusters via electron-electron coupling in a scaled up version. Here we lay the ground for the basic functional unit with long qubit registers, provide the theory and experimental verification of correlated qubit states, and demonstrate the Deutsch algorithm. Experiments were performed on a qubyte plus one nuclear spin in a solid state system.

    Since 1991, fluoridated salt has been on sale in household-size packages in Germany. Potassium or sodium fluoride is added to iodized salt until the fluoride concentration reaches 250 mg/kg. The use of fluoridated salt to prevent caries is officially recommended by the Deutsche Gesellschaft für Zahn-, Mund- und Kieferheilkunde (DGZMK) and several other associations and groups interested in public health. In the course of the past thirteen years, the market share of fluoridated and iodized domestic salt rose to 63.1% in Germany. However, this positive development must not obscure the fact that fluoridated and iodized salt is still not allowed to be used in restaurant or cafeteria kitchens. This restriction now needs to be revoked in view of the fact that many children, adolescents and adults take their main meals in cafeterias or restaurants. Scientific studies have demonstrated beyond doubt that using fluoridated and iodized salt in cafeteria kitchens poses no problem whatever.

    Surface freezing, at temperatures up to a few degrees above the equilibrium melting point, has been observed for intermediate chain length (16≤ i≤ 50) n-alkanes [B. M. Ocko, X. Z. Wu, E. B. Sirota, S. K. Sinha, O. Gang and M. Deutsch, Phys. Rev. E, 1997, 55, 3164-3182]. Our recent experimental results suggest that surface freezing is also the first step when highly supercooled nanodroplets of n-octane crystallize. Our data yield surface and bulk nucleation rates on the order of ˜1015/cm2.s and ˜1022/cm3.s, respectively. Complementary molecular dynamics simulations also show that the surface of the droplet freezes almost immediately, and freezing of the remainder of the droplet progresses in a layer-by-layer manner.

    We present an experimental study of the energy transfer in the bulk of a turbulent flow with small amount long-chain polymer additives. By varying the Reynolds numbers Rλ, Wissenberg number Wi and polymer concentration φ. We test quantitively the elastic theory proposed by de Gennes and Tabor (Europhys. Lett., 1986; Physica A, 1986). The rate of energy transfer by polymer elasticity as inferred from the theory is consistent with that measured from the second order Eulerian structure functions. The unknown parameter n in the theory, which represents the flow topology of the stretching field, is found to be nearly 1. Based on energy transfer rate balance, We propose an elastic length scale, rɛ, which describes the effect of polymer elasticity on turbulence energy cascade and captures the scale dependence of the elastic energy transfer rate. We are grateful to the Max Planck Society, the Alexander von Humboldt Foundation and the Deutsche Forschungsgemeinschaft for their support.

    The Kaiser Wilhelm Institute for Anthropology, Human Genetics and Eugenics in Berlin-Dahlem was the centre of scientific racism in Nazi Germany. Its bad history culminated in a research project to analyse the molecular basis of racial differences in the susceptibility to various infectious diseases such as tuberculosis. Josef Mengele, a former postdoc of the director of the institute, Otmar von Verschuer, collected blood samples and other material in Auschwitz from families and twins of Jews and Gypsies. The blood samples were analysed by Günther Hillmann in the Berlin laboratory of Nobel Prize winner Adolf Butenandt. Butenandt had just moved to Tübingen. The project was paid for by the Deutsche Forschungsgemeinschaft. Butenandt, Hillmann and von Verschuer made scientific careers in the Federal Republic. To the present day this past has not been acknowledged by the Max-Planck-Gesellschaft as part of its history.

    Wind tunnel tests of an advanced technology airfoil, the CAST 10-2/DOA 2, were conducted in the Langley 0.3-Meter Transonic Cryogenic Tunnel (0.3-m TCT). This was the third of a series of tests conducted in a cooperative airfoil research program between the National Aeronautics and Space Administration and the Deutsche Forschungsund Versuchsanstalt fur Luft- und Raumfahrt e. V. For these tests, temperature was varied from 270 K to 110 K at pressures from 1.5 to 5.75 atmospheres. Mach number was varied from 0.60 to 0.80, and the Reynolds number (based on airfoil chord) was varied from 2 to 20 million. The aerodynamic data for the 7.62 cm chord airfoil model used in these tests is presented without analysis. Descriptions of the 0.3-m TCT, the airfoil model, the test instrumentation, and the testing procedures are included.

    Abstract Europe has one of the best-known Lepidopteran faunas in the world, yet many species are still being discovered, especially in groups of small moths. Here we describe a new gracillariid species from the south-eastern Alps, Callisto basistrigella Huemer, Deutsch & Triberti, sp. n. It shows differences from its sister species Callisto coffeella in morphology, the barcode region of the cytochrome c oxidase I gene and the nuclear gene histone H3. Both Callisto basistrigella and Callisto coffeella can co-occur in sympatry without evidence of admixture. Two Callisto basistrigella specimens show evidence of introgression. We highlight the importance of an integrative approach to delimit species, combining morphological and ecological data with mitochondrial and nuclear sequence data. Furthermore, in connection with this study, Ornix blandella Müller-Rutz, 1920, syn. n. is synonymized with Callisto coffeella (Zetterstedt, 1839). PMID:25632257

    As part of an international collaboration, the Stanford Linear Accelerator Center (SLAC) klystron group has designed, fabricated, and tested a 60-Hz, 3-μs, 150-MW S-band klystron built for Deutsches Elektronen Synchrotron (DESY). A test diode with a 535-kV, 700-A electron beam was constructed to verify the gun operation. The first klystron was built and successfully met design specifications. The 375-MW electron beam represents a new record for SLAC accelerator klystrons in terms of voltage, current, energy, and ruggedness of design. The rf output power is a 150% increase over the S-band tubes currently used in the two-mile-long linear accelerator at SLAC. This paper discusses design issues and experimental results of the diode and klystron.

    Industrial design of electrostatic precipitators is based on the transport theory developed by Deutsch (1922), which assumes that transverse turbulent mixing is effective enough to maintain the concentration profile uniform throughout the cross section (i.e., turbulent diffusivity is assumed infinite). To improve understanding of turbulent particle dispersion under the influence of electrostatic forces, a database on particle trajectories was first generated, based on the flow field from a direct numerical simulation of a plate-plate precipitator. The effect of various parameters, such as particle size, charge and particle migration velocity, on dispersion and collection efficiency was investigated. Results show that particle concentration profiles are not uniform due to finite values of turbulent diffusion coefficient. The simulations indicate that the early stages of particle collection are controlled by particle migration velocity, while final stages are controlled by turbulence diffusion mechanisms.

    2009-11-01

    This article presents results from a qualitative study on how the Honduran secondary education programme, Sistema de Aprendizaje Tutorial (SAT), attempts to "undo gender" (Deutsch 2007: 122) by encouraging students to rethink gender relations in their everyday lives in a way that reflects their increased consciousness of gender equality. My findings suggest that SAT increased women's gender consciousness and this heightened their desire for change in the domestic sphere. In some instances, women were able to negotiate a new sharing of responsibilities with their spouses. There are several features of SAT that make it a transformative innovation in education: (1) gender is mainstreamed into the curriculum; (2) gender is linked with the larger concept of justice; (3) students engage in reflection, dialogue and debate; (4) teachers are given the opportunity to reflect critically on their understanding of gender in professional development sessions; and (5) it emphasises that undoing gender requires change among individuals and in social structures such as the family.

After briefly discussing plans for a German research institute before World War I, the article examines the political strategies and networks that Emil Kraepelin used to recruit support for the institute. It argues that his efforts at psychiatric governance can best be understood as a form of völkisch corporatism which sought to mobilize and coordinate a group of players in the service of higher biopolitical and hygienic ends. The article examines the wartime arguments used to justify the institute, the list of protagonists actively engaged in recruiting financial and political support, the various social, scientific and political networks that they exploited, and the local contingencies that had to be negotiated in order to found the research institute.

    The computationally most expensive step in conventional RPA implementations is the calculation of the independent particle polarizability χ0. We present an algorithm that calculates χ0 using the Green's function in real space and imaginary time. In combination with optimized non-uniform frequency and time grids the correlation energy on the random phase approximation level can be calculated efficiently with a computational cost that grows only cubically with system size. We apply this approach to calculate RPA defect energies of silicon using unit cells with up to 250 atoms and 128 CPU cores. Furthermore, we show how to extent the algorithm to the GW framework of Hedin and solve the Dyson equation for the Green's function with the same computational effort.

    The Rosetta mission is a milestone in terms of science and public outreach. The European Space Agency and the Deutsches Zentrum für Luft- und Raumfahrt in particular did a marvellous job of sparking global public interest, driven by various events throughout the mission. In contrast, the actions of the Max Planck Society research group in charge of the high resolution Optical, Spectroscopic, and Infrared Remote Imaging System were, in my opinion, the cause of some concern and bring to light an important debate in the relationship between outreach and science. This article seeks to review the outreach that surrounded the Rosetta mission and to highlight both the best practice that made it a success and the bad practice that set some aspects behind.

    Quantum computers, besides offering substantial computational speedups, are also expected to preserve the privacy of a computation. We present an experimental demonstration of blind quantum computing in which the input, computation, and output all remain unknown to the computer. We exploit the conceptual framework of measurement-based quantum computation that enables a client to delegate a computation to a quantum server. Various blind delegated computations, including one- and two-qubit gates and the Deutsch and Grover quantum algorithms, are demonstrated. The client only needs to be able to prepare and transmit individual photonic qubits. Our demonstration is crucial for unconditionally secure quantum cloud computing and might become a key ingredient for real-life applications, especially when considering the challenges of making powerful quantum computers widely available.

    The European x-ray free electron laser is under construction at Deutsches Elektronen-Synchrotron (DESY). The electron beam energy of up to 17.5 GeV will be achieved by using superconducting accelerator technology. Final prototyping, industrialization, and new infrastructure are the actual challenges with respect to the accelerating cavities. This paper describes the preparation strategy optimized for the cavity preparation procedure in industry. For the industrial fabrication and preparation, several new hardware components have been already developed at DESY. The design and construction of a semiautomated rf-measurement machine for dumbbells and end groups are described. In a collaboration among FNAL, KEK, and DESY, an automatic cavity tuning machine has been designed and four machines are under construction. The functionality of these machines with special attention to safety aspects is described in this paper. A new high pressure rinsing system has been developed and is operational.

    KAMEDIN is a teleradiology project of "Deutsche Telekom". ISDN based image transfer, visualisation and online-presentation of digital radiological images is performed. In this study the suitability of the KAMEDIN-system has been tested in a clinical environment. The software has been adapted to the requirements of radiological image visualisation. During 6 months over 50 conferences took place with an average of 36 CT-slices per patient. The amount of time was approximately 10 min for conference preparation, 20 min for image transfer and 8 min for conferencing. Software problems occurred and were solved. Image quality on the monitor as well as online presentation including "simultaneous cursors" showed high performance and achieved high acceptance by the clinicians. Thus KAMEDIN is a useful teleradiology system, especially if the system is adapted to the requirements of radiology departments. PMID:8924455

    Optical diagnostics, providing images of accelerated particle beams using radiation emitted by particles impinging a radiator, typically a fluorescent screen, has been extensively used, especially on electron linacs, since the 1970's. Higher intensity beams available in the last decade allow extending the use of beam imaging techniques to perform precise measurements of important beam parameters such as emittance, energy, and energy spread using optical transition radiation (OTR). OTR-based diagnostics systems are extensively used on the superconducting TESLA Test Facility (TTF) linac driving the vacuum ultraviolet free electron laser (VUV-FEL) at the Deutsches Elektronen-Synchrotron facility. Up to 30 optical diagnostic stations have been installed at various positions along the 250-m-long linac, each equipped with a high-performance digital camera. This paper describes the new approach to the design of the hardware and software setups required by the complex topology of such a distributed camera system.

    The Stratospheric Observatory for Infrared Astronomy (SOFIA) is a joint project between NASA and Deutsches Zentrum fuer Luft- und Raumfahrt (DLR), the German Space Agency. SOFIA is based in a Boeing 747 SP and flown in the stratosphere to observe infrared wavelengths unobservable from the ground. In 2007 Dryden Flight Research Center (DFRC) inherited and began work on improving the plane and its telescope. The improvements continue today with upgrading the plane and improving the telescope. The Observatory Verification and Validation (V&V) process is to ensure that the observatory is where the program says it is. The Telescope Status Display (TSD) will provide any information from the on board network to monitors that will display the requested information. In order to assess risks to the program, one must work through the various threats associate with that risk. Once all the risks are closed the program can work towards improving the observatory.

  9. Active Mesogenic Droplets: Impact of Liquid Crystallinity and Collective Behavior

    NASA Astrophysics Data System (ADS)

    Bahr, Christian

    Droplets of common mesogenic compounds show a self-propelled motion when immersed in aqueous solutions containing ionic surfactants at concentrations well above the critical micelle concentration. After introducing some general properties of this type of artificial microswimmer, we focus on two topics: the influence of liquid crystallinity on the swimming behavior and the collective behavior of ensembles of a larger number of droplets. The mesogenic properties are not essential for the basic mechanism of self-propulsion, nevertheless they considerably influence the swimming behavior of the droplets. For instance, the shape of the trajectories strongly depends on whether the droplets are in the nematic or isotropic state. The droplet swimmers are also ideally suited for the study of collective behavior: Microfluidics enables the generation of large numbers of identical swimmers and we can tune their buoyancy. We report on the collective behavior in three-dimensional environments. Supported by the Deutsche Forschungsgemeinschaft (SPP 1726 ``Microswimmers'').

  10. Topologically non-trivial electronic and magnetic states in doped copper Kagome lattices

    We present a theoretical investigation of doped copper kagome materials based on natural minerals Herbertsmithite [ZnCu3(OH)6Cl2] and Barlowite[Cu4(OH)6FBr]. Using ab-initio density functional theory calculations we estimate the stability of the hypothetical compounds against structural distortions and analyze their electronic and magnetic properties. We find that materials based on Herbertsmithite present an ideal playground for investigating the interplay of non-trivial band-topology and strong electronic correlation effects. In particular, we propose candidates for the Quantum Spin Hall effect at filling 4/3 and the Quantum Anomalous Hall effect at filling 2/3. For the Barlowite system we point out a route to realize a Quantum Spin Liquid. This work was supported by Deutsche Forschungsgemeinschaft under Grant No. SFB/TR 49 and the National Science Foundation under Grant No. PHY11-25915.

  11. Time travel paradoxes, path integrals, and the many worlds interpretation of quantum mechanics

    NASA Astrophysics Data System (ADS)

    2004-06-01

    We consider two approaches to evading paradoxes in quantum mechanics with closed timelike curves. In a model similar to Politzer’s, assuming pure states and using path integrals, we show that the problems of paradoxes and of unitarity violation are related; preserving unitarity avoids paradoxes by modifying the time evolution so that improbable events become certain. Deutsch has argued, using the density matrix, that paradoxes do not occur in the “many worlds interpretation.” We find that in this approach account must be taken of the resolution time of the device that detects objects emerging from a wormhole or other time machine. When this is done one finds that this approach is viable only if macroscopic objects traversing a wormhole interact with it so strongly that they are broken into microscopic fragments.

    The aim of this study was to investigate the suitability of the invA-based polymerase chain reaction (PCR) assay for the specific detection of Salmonella in organs of experimentally infected pigs and to compare these results to classical bacterial culture. While the PCR conditions specified in the "Deutsche Industrie Norm", DIN 10135 (section 35 LMBG, 1999), cutle based on the publication of Rahn et al. 1992, revealed various unspecific amplification products, modifications of the PCR conditions allowed the specific amplification of the invA fragment from inner organs. The modified PCR assay correlates exactly with cultivation results (as required by DIN Norm 6579) and enables the detection of Salmonella within 48 hours with equal sensitivity compared to routine cultivation.

    To improve the individual health profile and to solve the growing overweight problem, a long-term change in the lifestyle to one which includes an energetically balanced combination of diet and activity is essential. Physical activity and the muscles involved are the primary means by which body composition and energy turnover are regulated. A state of imbalance has decisive consequences on the development of atherogenic and inflammatory risk factors. Additionally, the aging process is significantly influenced by the long-term retention or loss of muscle mass. The Deutsche Gesellschaft für Sportmedizin und Prävention (German Society for Sports Medicine and Prevention, a registered association) offers within the concept of a therapeutic lifestyle change, an educational program for overweight adults (M.O.B.I.L.I.S.).

    An evaluation of the cone-shaped pickup performance as a part of the high bandwidth bunch arrival-time monitors (BAMs) for a low charge sub-10 fs arrival-time measurements is presented. Three sets of pickups are installed at the free electron laser FLASH at Deutsches Elektronen-Synchrotron, the quasi-cw SRF accelerator ELBE at the Helmholtz-Zentrum Dresden-Rossendorf and the SwissFEL injector test facility at Paul Scherrer Institute. Measurements and simulations are in good agreement and the pickups fulfill the design specifications. Utilizing the high bandwidth BAM with the cone-shaped pickups, an improvement of the signal slope by a factor of 10 is demonstrated at ELBE compared to the BAM with a low bandwidth.

    This report presents the results of laboratory characterization and testing of two samples (designated 20406 and 20407) of residual waste collected from tank S-112 after final waste retrieval. These studies were completed to characterize the residual waste and assess the leachability of contami¬nants from the solids. This is the first report from this PNNL project to describe the composition and leach test data for residual waste from a salt cake tank. All previous PNNL reports (Cantrell et al. 2008; Deutsch et al. 2006, 2007a, 2007b, 2007c) describing contaminant release models, and characterization and testing results for residual waste in single-shell tanks were based on samples from sludge tanks.

    We report the development and implementation of four FPGA-based predistortion-type klystron linearization algorithms. Klystron linearization is essential for the realization of ILC, since it is required to operate the klystrons 7% in power below their saturation. The work presented was performed in international collaborations at the Fermi National Accelerator Laboratory (FNAL), USA and the Deutsches Elektronen Synchrotron (DESY), Germany. With the newly developed algorithms, the generation of correction factors on the FPGA was improved compared to past algorithms, avoiding quantization and decreasing memory requirements. At FNAL, three algorithms were tested at the Advanced Superconducting Test Accelerator (ASTA), demonstrating a successful implementation for one algorithm and a proof of principle for two algorithms. Furthermore, the functionality of the algorithm implemented at DESY was demonstrated successfully in a simulation.

    The correlation matrix formalism is used to study temporal aspects of the stock market evolution. This formalism allows to decompose the financial dynamics into noise as well as into some coherent repeatable intraday structures. The present study is based on the high-frequency Deutsche Aktienindex (DAX) data over the time period between November 1997 and September 1999, and makes use of both the corresponding returns as well as volatility variations. One principal conclusion is that a bulk of the stock market dynamics is governed by the uncorrelated noise-like processes. There exists, however, a small number of components of coherent short-term repeatable structures in fluctuations that may generate some memory effects seen in the standard autocorrelation function analysis. Laws that govern fluctuations associated with those various components are different, which indicates an extremely complex character of the financial fluctuations.

Kaplan, Karl W. Deutsch [Mesjasz 1988], and ending with contemporary ideas of broadened concepts of security proposed by the Copenhagen School [Buzan et al 1998]. At present it may be even stated that the new military and non-military threats to contemporary complex society, such as low-intensity conflicts, regional conflicts, terrorism, environmental disturbances, etc. cannot be embraced without ideas taken from modern complex systems studies.

    In patients with chronic liver disease, the reliability of various criteria generally used to diagnose impaired glucose tolerance and diabetes was evaluated. Twenty-one patients with chronic persistent hepatitis, 68 patients with chronic active hepatitis and 57 patients with liver cirrhosis were studied. All subjects underwent an oral glucose tolerance test (75 g). Impaired glucose tolerance and diabetes were diagnosed according to the criteria established by: the National Diabetes Study Group; Fajans and Conn; the European Diabetes Study Group; Deutsche Diabetes Gesellschaft; Kobberling & Creutzfeld criteria 1 and 2; Wilkerson; and the University Group Diabetes Program. The results obtained are in partial agreement with other reported data, showing a high prevalence of both impaired glucose tolerance and diabetes in chronic liver disease, with a positive correlation to the severity of hepatic involvement. However, our results show that the agreement among the criteria most frequently used for diagnosing impaired glucose tolerance and diabetes is still far from satisfactory.

Seit den 90er Jahren versuchen immer mehr deutsche Unternehmen diesen veränderten Anforderungen mit der Einführung eines Ganzheitlichen Produktionssystems (GPS) zu begegnen. Ganzheitliche Produktionssysteme sind dabei in ihren Grundlagen an das Toyota Produktionssystem angelehnt, vereinigen aber auch weitere Methoden zu einem unternehmensspezifischen Regelwerk. Im Rahmen des langfristigen Trends zu unternehmensindividuellen Produktionssystemen wird sowohl in der Industrie als auch in der Forschung intensiv über das Toyota Produktionssystem, Lean Production, Lean Management und Ganzheitliche Produktionssysteme diskutiert, werden Konzepte zu Implementierung und Betrieb erstellt und die Wirtschaftlichkeit untersucht.

    The aim of every German surgeon is to ensure an optimal quality of performance in every sphere of surgical activity in the German Federal Republic. Cooperation of the Deutsche Gesellschaft für Chirurgie (German Surgical Society) and the Berufsverband der Deutschen Chirurgen (professional association of German surgeons) is intended to achieve this aim by a system which offers all surgeons working independently in clinics, hospitals and private practice the possibility, on an absolutely voluntary basis, for data on their methods of treatment and results to be recorded centrally and stored in such a way that a comparison of certain criteria of quality assessment of their work is available for them. In the event of a marked difference in quality, an advisory committee of experienced surgeons specially appointed with the confidence of all involved should try to clarify the reason for this on the spot and seek ways to help.

    Mackenbach, Johan

    2005-01-01

    This essay reviews some of the sources of idealism in public health, on the basis of an intellectual journey to Kos (home to Hippocrates and his altruistic legacy), Dresden (where the Deutsches Hygiene Museum illustrates the historical connections between fascism and public health), and Utopia (exemplified by Etienne Cabet's Icarie, a fantasy of an ideal city which has nevertheless been partly realized). It is suggested that the large-scale altruism of public health has to be balanced with the value of individual autonomy, and that some degree of dreaming of a better and healthier world is indispensable for further progress in public health. The main conclusion is that the ethical foundations of public health are not always self-evident, and that critical reflection on these foundations was, is, and will always be necessary.

    2016-09-01

    An oblique pulsar magnetosphere with a plasma conductivity is studied by using a pseudo-spectral method. In the pseudo-spectral method, the time-dependent Maxwell equations are solved, both electric and magnetic fields are expanded in terms of the vector spherical harmonic functions in spherical geometry and the divergencelessness of magnetic field is analytically enforced by a projection method. The pulsar magnetospheres in infinite (i.e., force free approximation) and finite conductivities are simulated and a family of solutions that smoothly transition from the Deutsch vacuum solution to the force-free solution are obtained. The sin2α dependence of the spin-down luminosity on the magnetic inclination angle α in which the full electric current density are taken into account is retrieved in the force-free regime.

    In 1997 BMBF, within the framework of an idea competition for future-oriented key technologies and their industrial utilization, called for project proposals from industries and research for so-called 'Leitprojekts'. An independent group of experts selected few project proposals form the many submitted, and prosed them to BMBF for promotion. One of these projects is the BMBF-Leitprojekt ADAPTRONIK which is introduced in this paper. The Leitprojekt ADAPTRONIK which is conducted under the responsibility of Deutsches Zentrum fuer Luft-und Raumfahrt e.V. in Brunswick, focuses on the strucutre-conforming integration of piezoelectric fibers and patches in structures for lightweight construction. It is aimed at active vibration and noise reduction, contour deformation and micro-positioning in the very sense of adaptronics in various industrial applications. The project targets are prototype assemblies from the fields of automotive industry, rail vehicles, mechanical engineering, medical engineering, and aerospace.

    In seiner 2007 erschienen Sammlung von Vorträgen und Essays beschäftigt sich Wolfgang Frühwald, mit der Frage "Wieviel Wissen brauchen wir?“ [1] Die Kernproblematik moderner Wissenschaft und Forschung sieht der Autor, emeritierter Ordinarius für Neuere Deutsche Literaturwissenschaft und von 1992 bis 1997 Präsident der Deutschen Forschungsgemeinschaft, einerseits in der zunehmenden Spezialisierung der Wissenschaftsbereiche, andererseits in der Gefahr der Abkoppelung der Naturwissenschaften von den Geisteswissenschaften. Wiederholt plädiert er dafür, über der rasanten Entwicklung beispielsweise in der Biologie und Physik, die historische, gesellschaftliche und besonders die ethische Dimension der Forschung nicht zu übersehen und fordert eine übergeordnete Theorie der Wissenschaft, die nur im Dialog zwischen den einzelnen Fachgebieten zu entwickeln sei.

    Acoustic data taken in the anechoic Deutsch-Niederlaendischer Windkanal (DNW) have documented the blade-vortex interaction (BVI) impulsive noise radiated from a 1/7-scale model main rotor of the AH-1 series helicopter. Averaged model-scale data were compared with averaged full-scale, in-flight acoustic data under similar non-dimensional test conditions using an improved data analysis technique. At low advance ratios (mu = 0.164 - 0.194), the BVI impulsive noise data scale remarkably well in level, waveform, and directivity patterns. At moderate advance ratios (mu = 0.224 - 0.270), the scaling deteriorates, suggesting that the model-scale rotor is not adequately simulating the full-scale BVI noise. Presently, no proved explanation of this discrepancy exists. Measured BVI noise radiation is highly sensitive to all of the four governing nondimensional parameters--hover tip Mach number, advance ratio, local inflow ratio, and thrust coefficient.

    The foundation of the competence network for rheumatology, which is funded by the "Bundesministerium für Bildung und Forschung" (BMBF) since 1999, succeeded to create a unique research structure in Germany: medical doctors and scientists from six university rheumatology centres (Berlin, Düsseldorf, Erlangen, Freiburg, Hannover und Lübeck/Bad Bramstedt) work closely together with scientists doing basic research at the Deutsches Rheuma-Forschungszentrum (DRFZ), with rheumatological hospitals, reha-clinics, and rheumatologists. Jointly they are searching for causes of systemic inflammatory rheumatic diseases and try to improve therapies-nationwide and with an interdisciplinary approach. The primary objective of this collaboration is to transfer new scientific insights more rapidly in order to improve methods for diagnosis and patients treatment.

  17. Influence of social motives on integrative negotiation: a meta-analytic review and test of two theories.

    PubMed

    De Dreu, C K; Weingart, L R; Kwon, S

    2000-05-01

    A meta-analysis of 28 studies examined support for the Theory of Cooperation and Competition (M. Deutsch, 1973) and Dual Concern Theory (D. G. Pruitt & J. Z. Rubin, 1986). Effects of social motive (prosocial vs. egoistic) and resistance to yielding (high vs. low vs. unknown) on contenting, problem solving, and joint outcomes were examined. Consistent with Dual Concern Theory, results showed that negotiators were less contentious, engaged in more problem solving, and achieved higher joint outcomes when they had a prosocial rather than egoistic motive, but only when resistance to yielding was high (or unknown) rather than low. The authors also explored the moderating effects of study characteristics and found effects for participation inducement (class exercise, participant pool), for publication status, and for treatment of no-agreement dyads.

    This is the first of two articles exploring in depth some of the early organizational strategies that were marshalled in efforts to found and develop the German Research Institute of Psychiatry (Deutsche Forschungsanstalt für Psychiatrie) in 1917. After briefly discussing plans for a German research institute before World War I, the article examines the political strategies and networks that Emil Kraepelin used to recruit support for the institute. It argues that his efforts at psychiatric governance can best be understood as a form of völkisch corporatism which sought to mobilize and coordinate a group of players in the service of higher biopolitical and hygienic ends. The article examines the wartime arguments used to justify the institute, the list of protagonists actively engaged in recruiting financial and political support, the various social, scientific and political networks that they exploited, and the local contingencies that had to be negotiated in order to found the research institute.

    HMG-CoA reductase inhibitors (statins) are among the most widely used hypolypemizing drugs with a pleiotropic activity. Numerous clinical trials have demonstrated that statins can have a significant effect in the prevention of cardiovascular diseases in the general population. In patients with renal failure, this drug preserves the hypolypemizing efficacy found in the general population without increasing their unwanted side-effects. The re-analysis of data from epidemiological studies conducted on the general population has confirmed that statins provide cardiovascular protection also in subjects with renal failure. These data have been partly confirmed by the findings made by 4D (Die Deutsche Diabetes Dialyse Studie) and Alert studies, conducted on diabetic patients on dialysis and patients with renal transplants, respectively. The results of other studies, such as AURORA, SHARP, REnal and Vascular End stage Disease, and ESPLANADE, clearly indicate that statins prevent cardiovascular disease in patients with renal insufficiency, just as they do in the general population.

    Targeted monitoring of analgesia, sedation and delirium, as well as their appropriate management in critically ill patients is a standard of care in intensive care medicine. With the undisputed advantages of goal-oriented therapy established, there was a need to develop our own guidelines on analgesia and sedation in intensive care in Germany and these were published as 2nd Generation Guidelines in 2005. Through the dissemination of these guidelines in 2006, use of monitoring was shown to have improved from 8 to 51% and the use of protocol-based approaches increased to 46% (from 21%). Between 2006–2009, the existing guidelines from the DGAI (Deutsche Gesellschaft für Anästhesiologie und Intensivmedizin) and DIVI (Deutsche Interdisziplinäre Vereinigung für Intensiv- und Notfallmedizin) were developed into 3rd Generation Guidelines for the securing and optimization of quality of analgesia, sedation and delirium management in the intensive care unit (ICU). In collaboration with another 10 professional societies, the literature has been reviewed using the criteria of the Oxford Center of Evidence Based Medicine. Using data from 671 reference works, text, diagrams and recommendations were drawn up. In the recommendations, Grade “A” (very strong recommendation), Grade “B” (strong recommendation) and Grade “0” (open recommendation) were agreed. As a result of this process we now have an interdisciplinary and consensus-based set of 3rd Generation Guidelines that take into account all critically illness patient populations. The use of protocols for analgesia, sedation and treatment of delirium are repeatedly demonstrated. These guidelines offer treatment recommendations for the ICU team. The implementation of scores and protocols into routine ICU practice is necessary for their success. PMID:20200655

    "The time will come when German medicine, too, will have to concern itself with the issue of a professional narcotiseur. Until then it will be our duty to keep the interest in narcosis, which has increased satisfactorily in the past years, alive." With this statement the editors of the journal "Der Schmerz" substantiated the publication og a German-speaking anestesiological journal in 1928. Ernst von der Porten, a professional anesthesist working in Hamburg was the chief initiator for the appearance of the new journal. Possible he was incited by his former teacher, the Eppendorf surgeon Paul Sudeck, to delve deeper into our special field. Very early Sudeck himself began to concern himself with anesthesiological questions and he found an ardent supporter of the idea of specialisation in anesthesiology (quite unheard of in Germany at that time) in Helmut Schmidt, a staff member. Schmidt habilitated on an anesthesiological theme and that again was reason enough for the editors to write an editorial about. Schmidt who one of the chief organizers of the "90. Tagung Deutscher Naturforscher und Arzte" in the late summer of 1928 was hindered by the surgeons on founding the Deutsche Narkosege-sellschaft (German Narcosis Society) with colleagues. After World War II German surgeons rethought their position, mainly influenced by Anglo-American narcosis specialists. After the foundation of the Deutsche Gesellschaft für Anaesthesiein the year 1953, the first professorate for the special field of anesthesiology was given to Karl Horatz--one of the founding members--10 years later. Not surprisingly the professorate was instituted at the university hospital in Eppendorf which could be called the cradle of German-speaking anesthesia. The following concerns itself with some of the impulses that were given by the "Neues Allgemeines Krankenhaus Eppendorf" and became important stepping stones in our special field through the decades.

    Hemodynamic monitoring and adequate volume-therapy, as well as the treatment with positive inotropic drugs and vasopressors are the basic principles of the postoperative intensive care treatment of patient after cardiothoracic surgery. The goal of these S3 guidelines is to evaluate the recommendations in regard to evidence based medicine and to define therapy goals for monitoring and therapy. In context with the clinical situation the evaluation of the different hemodynamic parameters allows the development of a therapeutic concept and the definition of goal criteria to evaluate the effect of treatment. Up to now there are only guidelines for subareas of postoperative treatment of cardiothoracic surgical patients, like the use of a pulmonary artery catheter or the transesophageal echocardiography. The German Society for Thoracic and Cardiovascular Surgery (Deutsche Gesellschaft für Thorax-, Herz- und Gefäßchirurgie, DGTHG) and the German Society for Anaesthesiology and Intensive Care Medicine (Deutsche Gesellschaft für Anästhesiologie und lntensivmedizin, DGAI) made an approach to ensure and improve the quality of the postoperative intensive care medicine after cardiothoracic surgery by the development of S3 consensus-based treatment guidelines. Goal of this guideline is to assess the available monitoring methods with regard to indication, procedures, predication, limits, contraindications and risks for use. The differentiated therapy of volume-replacement, positive inotropic support and vasoactive drugs, the therapy with vasodilatators, inodilatators and calcium sensitizers and the use of intra-aortic balloon pumps will also be addressed. The guideline has been developed following the recommendations for the development of guidelines by the Association of the Scientific Medical Societies in Germany (AWMF). The presented key messages of the guidelines were approved after two consensus meetings under the moderation of the Association of the Scientific Medical

  4. Ionization Cross Sections and Dissociation Channels of DNA Bases by Electron Collisions

    Free secondary electrons are the most abundant secondary species in ionizing radiation. Their role in DNA damage, both direct and indirect, is an active area of research. While indirect damage by free radicals, particularly by the hydroxyl radical generated by electron collision with water. is relatively well studied, damage by direct electron collision with DNA is less well understood. Only recently Boudaiffa et al. demonstrated that electrons at energies well below ionization thresholds can induce substantial yields of single- and double-strand breaks in DNA by a resonant, dissociative attachment process. This study attracted renewed interest in electron collisions with DNA, especially in the low energy region. At higher energies ionization becomes important. While Monte Carlo track simulations of radiation damage always include ionization, the probability of dissociative ionization, i.e., simultaneous ionization and dissociation, is ignored. Just like dissociative attachment, dissociative ionization may be an important contributor to double-strand breaks since the radicals and ions produced by dissociative ionization, located in the vicinity of the DNA coil, can readily interact with other parts of the DNA. Using the improved binary-encounter dipole (iBED) formulation, we calculated the ionization cross sections of the four DNA bases, adenine, cytosine, guanine, and thymine, by electrons at energies from threshold to 1 KeV. The present calculation gives cross sections approximately 20% lower than the results by Bemhardt and Paretzke using the Deutsch-Mark and Binary-Encounter-Bethe (BEB) formalisms. The difference is most likely due to the lack of a shielding term in the dipole potential used in the Deutsch-Mark and BEB formalisms. The dissociation channels of ionization for the bases are currently being studied.

  5. The glissando illusion and handedness.

    This article reports the first study of the glissando illusion, which was created and published as a sound demonstration by Deutsch [Deutsch, D. (1995). Musical illusions and paradoxes. La Jolla: Philomel Records (compact disc)]. To experience the illusion, each subject was seated in front of two stereophonically separated loudspeakers, with one to his left and the other to his right. A sound pattern was presented that consisted of a synthesized oboe tone of constant pitch, together with a sine wave whose pitch repeatedly glided up and down (the glissando). These two components alternated continuously between the loudspeakers such that when the oboe tone emanated from the loudspeaker on the left, the glissando emanated from the loudspeaker on the right; and vice versa. The oboe tone was perceived correctly as switching between loudspeakers; however, the segments of the glissando appeared to be joined together seamlessly, such that a single, continuous tone was heard, which appeared to be moving slowly around in space in accordance with its pitch motion. Right-handers (n=22) tended strongly to hear the glissando move between left and right, and also between low and high in space, as its pitch moved between low and high. More specifically, it was frequently heard as tracing an elliptical path aligned diagonally between a position low and to the left when its pitch was lowest, and high and to the right when its pitch was highest. Non-right-handers (n=42) perceived the illusion in statistically different ways. The handedness correlates and other implications of the glissando illusion are discussed. PMID:17624379

    Purpose: This is an official guideline, published and coordinated by the Arbeitsgemeinschaft Gynäkologische Onkologie (AGO, Study Group for Gynecologic Oncology) of the Deutsche Krebsgesellschaft (DKG, German Cancer Society) and the Deutsche Gesellschaft für Gynäkologie und Geburtshilfe (DGGG, German Society for Gynecology and Obstetrics). The number of cases with vulvar cancer is on the rise, but because of the former rarity of this condition and the resulting lack of literature with a high level of evidence, in many areas knowledge of the optimal clinical management still lags behind what would be required. This updated guideline aims to disseminate the most recent recommendations, which are much clearer and more individualized, and is intended to create a basis for the assessment and improvement of quality care in hospitals. Methods: This S2k guideline was drafted by members of the AGO Committee on Vulvar and Vaginal Tumors; it was developed and formally completed in accordance with the structured consensus process of the Association of Scientific Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF). Recommendations: 1. The incidence of disease must be taken into consideration. 2. The diagnostic pathway, which is determined by the initial findings, must be followed. 3. The clinical and therapeutic management of vulvar cancer must be done on an individual basis and depends on the stage of disease. 4. The indications for sentinel lymph node biopsy must be evaluated very carefully. 5. Follow-up and treatment for recurrence must be adapted to the individual case. PMID:27765958

    The article discusses the consequences for neurology as a discipline which resulted from neurologists' participation in the crimes committed under National Socialism (NS). Chronologically, the current literature distinguishes mainly four overlapping stages: (1) a first phase was characterized by legal persecution and "denazification", which was also the time of the Nuremberg doctors' trial in which no neurologists were on trial. A detailed documentation of the trial for the German medical profession was published by Alexander Mitscherlich. (2) In the subsequent practice of wide amnestying and reintegration of former Nazi followers during the 1950s, neurologists were no exception as its elite continued in their positions. The year 1953 was the year of the Lisbon scandal, when chiefly Dutch representatives protested against the participation of Julius Hallervorden in the International Congress of Neurology. The newly founded societies, the German Society for Neurology (Deutsche Gesellschaft für Neurologie, DGN) and the German Society for Psychiatry and Neurology (Deutsche Gesellschaft für Psychiatrie und Neurologie, DGPN), unanimously supported their member. (3) The next period was characterized by a nascent criticism of the prevailing attitude of covering up the crimes committed by physicians during the Nazi period. The discovery of incriminating brain sections at various Max Planck Institutes brought neurology to the focus of the debate. (4) Since the 1980s and 1990s historians (of medicine) have been systematically examining medicine's Nazi past in a professional way, which resulted in a noticeable increase of knowledge. Additionally, a new generation of scholars provoked a change of mind insofar as they recognized medicine's responsibility for the crimes committed between 1933 and 1945. We expect that future historical research will further elucidate the history of neurology during the NS regime and have consequences for our current understanding of research

    Data acquired on April 13, 1994 and on October 4, 1994 from the X-band Synthetic Aperture Radar on board the space shuttle Endeavour were used to generate interferometric fringes, which were overlaid on the X-SAR image of Kilauea. The volcano is centered in this image at 19.58 degrees north latitude and 155.55 degrees west longitude. The image covers about 9 kilometers by 13 kilometers (5.6 miles by 8 miles). The X-band fringes correspond clearly to the expected topographic image. The yellow line indicates the area below which was used for the three-dimensional image using altitude lines. The yellow rectangular frame fences the area for the final topographic image. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory. X-SAR was developed by the Dornier and Alenia Spazio companies for the German space agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian space agency, Agenzia Spaziale Italiana (ASI), with the Deutsche Forschungsanstalt fuer Luft und Raumfahrt e.V.(DLR), the major partner in science, operations and data processing of X-SAR. The Instituto Ricerca Elettromagnetismo Componenti Elettronici (IRECE) at the University of Naples was a partner in interferometry analysis.

    Hintergrund: Medizinisch und gesellschaftlich bedingte Faktoren führen zu einer Zunahme hospitalisierter Frauen mit Risikoschwangerschaft. Die Unvorhersehbarkeit des weiteren Schwangerschaftsverlaufs kann zu Ungewissheit und je nach Bewältigungsstrategie auch zu Stress führen. Ziele: Ziele dieser Studie waren die deutsche Übersetzung und Adaptation der USS-HRPV. Methode: Die Übersetzung in die deutsche Sprache erfolgte mittels Vor- und Rückwärtsübersetzung. Die zwei Phasen umfassende Adaptation wurde mit hospitalisierten Frauen mit Risikoschwangerschaft (n = 24) sowie diplomierten Hebammen (n = 10) durchgeführt und beruht sowohl auf kognitiven Interviews wie auch auf einer Testung der Inhaltsvalidität mittels «Content Validity Index» (CVI). Nach jeder Erhebungsphase wurde das Messinstrument mithilfe von Fachexpertinnen (n = 3) modifiziert. Ergebnisse: Der für jedes Item berechnete CVI (I-CVI) ergab in der ersten Phase für beide Teilstichproben Werte zwischen 0,10 und 1,0, der über das gesamte Messinstrument berechnete CVI (S-CVI/Ave) einen Wert von 0,62 respektive 0,70. Die I-CVI-Werte der hospitalisierten Frauen mit Risikoschwangerschaft der zweiten Phase lagen zwischen 0,17 und 1,0, der S-CVI/Ave betrug 0,73. Insgesamt wurden unter Berücksichtigung aller Daten 44 der ursprünglich 86 Items entfernt und 28 sprachlich verändert. Schlussfolgerungen: Aufgrund der methodischen Vorgehensweise konnte eine solide Ausgangslage für die weiteren Validierungsschritte zur Weiterentwicklung des Messinstrumentes für den deutschsprachigen Raum erarbeitet werden.

    Data management in geosciences, especially at university and other research institutes commonly isn't very well coordinated. Due to changing staff and limited funding this topic has no priority in general. The process to implement policies regulating data management in an university institute is complex. First of all existing structures and workflows had to be reviewed. That means an inventory of different data sets, reviewing quality tests, but also data requirements of scientists as well as their willingness to follow rules simplifying their work. Awareness of complying with regulations is essential for the acceptance of policies. A leading team, formed by several scientists, will bring together different points of view to control the development of institutional policies. Determining the actual state of personal data management using a questionary was one of the activities in the project EWIG (Developing workflow components for long-term archiving of research data in geosciences). The intention of the project is to support geoscientists in transferring their data in a standardized way for storage in digital long-term archives and in using documented data from these archives. Project partners are Deutsches GeoForschungsZentrum Potsdam and Konrad-Zuse-Zentrum für Informationstechnik Berlin. Other activities were to discuss existing problems and approved solutions with many institutions and tried to find out, where are the gaps in already realized workflows and which structures could be an ideal model to be generalized. Policies for the workflow independent from the working area will be defined. University lectures were started to teach future scientific generations from the beginning on how to deal with all sorts of different data in a transparent way. Their feedback will be used to improve data documentations and data curation, so that the re-use of archived research data will be encouraged.

    We are pleased to present the proceedings from the Astronomy at High Angular Resolution 2011: The central kiloparsec in galactic nuclei conference. The conference took place in the Physikzentrum of the Deutsche Physikalische Gesellschaft (DPG), Bad Honnef, Germany, from 28 August to 2 September 2011. It was the second conference of this kind, following the Astronomy at High Angular Resolution conference held in Bad Honnef, three years earlier in 2008. The main objective of the conference was to frame the discussion of the broad range of physical processes that occur in the central 100pc of galactic nuclei. In most cases, this domain is difficult to probe through observations. This is mainly because of the lack of angular resolution, the brightness of the central engine and possible obscurations through dust and gas, which play together in the central regions of host galaxies of galactic nuclei within a broad range of activity. The presence of large amounts of molecular and atomic (both neutral and ionized) gas, dust and central engines with outflows and jets implies that the conditions for star formation in these regions are very special, and probably different from those in the disks of host galaxies. Numerous presentations covering a broad range of topics, both theoretical and experimental, those related to research on Active Galactic Nuclei and on a wide range of observed wavelengths were submitted to the Scientific Organizing Committee. Presentations have been grouped into six sessions: The nuclei of active galaxies The Galactic Center The immediate environment of Super Massive Black Holes The physics of nuclear jets and the interaction of the interstellar medium The central 100pc of the nuclear environment Star formation in that region The editors thank all participants of the AHAR 2011 conference for their enthusiasm and their numerous and vivid contributions to this conference.

    I first sketch the history of the German Physical Society (Deutsche Physikalische Gesellschaft,DPG) from its founding by six young Berlin scientists as the Physical Society of Berlin (Physikalische Gesellschaft zu Berlin) in 1845, through its renaming as the DPG in 1899 and its rise to prominence by the beginning of the 1930s. I then turn to the history of the DPG during the Third Reich, which can be divided into two periods, from the transfer of power in Germany to the Nazis in 1933 to 1940, and from 1941 to 1945. During the first period, Johannes Stark (1874 1957), one of the leaders of the “German Physics” (Deutsche Physik) movement, attempted to gain election as the Chairman of the DPG in September 1933 but was repulsed. A period of relative autonomy of the DPG from Nazi ideology and policies ensued, which gradually was transformed into one of accommodation, until at the end of the 1938, Peter Debye (1884 1966), then Chairman of the DPG, bowed to governmental demands and Nazi activists in the DPG, introduced Nazi principles, and strongly advised the Jewish members of the DPG to withdraw from it. Debye left Germany in early 1940, and after a transitional period in which Jonathan Zenneck (1871 1959) served as Acting Chairman, Carl Ramsauer (1879 1955) was elected Chairman of the DPG in December 1940, thus opening the second period, the Ramsauer era, which lasted from 1941 until the end of the war in 1945. Ramsauer oversaw the self-coordination (Selbstgleichschaltung) of the DPG to the Nazi regime, and as an industrial physicist he led the DPG to establish ever more alliances with powerful figures in the military-industrial complex of Nazi Germany, which worked to the advantage both of Ramsauer and the DPG and to that of the Nazi regime during the course of the war. Finally, as the military defeat of Germany loomed, Ramsauer took steps aimed at insuring the survival of German physics in the postwar period. After the war, he masked the wartime activities of

    Gynaecological cancer centres have been established nationwide in Germany since 2008 according to the certification system of the German Cancer Society (Deutsche Krebsgesellschaft e. V. [DKG]) and the German Society for Gynaecology and Obstetrics (Deutsche Gesellschaft für Gynäkologie und Geburtshilfe e. V. [DGGG]). However, patient access to the certified gynaecological cancer centres is currently only possible through direct referrals. A longitudinal structure with the corresponding long-term documentation of both the high-grade precursors as well as the cancers does not exist as yet. According to the aims of the National Cancer Plan, a corresponding structure for the cancer entity "cervix carcinoma" should be established. The foundations for such a structure are appropriate diagnostic units that are responsible, after nationwide screening, for clarification according to guideline-conform principles. On the basis of the vote of the certification commission for gynaecological cancer centres under the chairmanship of the DKG, the Working Group for Gynaecological Oncology (Arbeitsgemeinschaft Gynäkologische Onkologie e. V. [AGO]), the Committee on Cervical Pathology and Colposcopy (Arbeitsgemeinschaft Zervixpathologie & Kolposkopie [AG-CPC]) and the DGGG the certification system for gynaecological dysplasia has been established. As a general principle, a distinction is made between the certification of a consulting practice for gynaecological dysplasia and a gynaecological dysplasia facility in order to integrate both outpatient and inpatient health-care facilities into the certification system. In analogy to the further catalogue of requirements from the DKG, quantitative and qualitative minimum numbers are demanded. Furthermore, the requirements of the certification process include a summary of patient information, the applied guidelines, continuing and further training, interdisciplinary cooperation in tumour boards, contents or, respectively, procedure

    Implementing policies for research data management to the end of data archiving at university institutions takes a long time. Even though, especially in geosciences, most of the scientists are familiar to analyze different sorts of data, to present statistical results and to write publications sometimes based on big data records, only some of them manage their data in a standardized manner. Much more often they have learned how to measure and to generate large volumes of data than to document these measurements and to preserve them for the future. Changing staff and limited funding make this work more difficult, but it is essential in a progressively developing digital and networked world. Results from the project EWIG (Translates to: Developing workflow components for long-term archiving of research data in geosciences), funded by Deutsche Forschungsgemeinschaft, will help on these theme. Together with the project partners Deutsches GeoForschungsZentrum Potsdam and Konrad-Zuse-Zentrum für Informationstechnik Berlin a workflow to transfer continuously recorded data from a meteorological city monitoring network into a long-term archive was developed. This workflow includes quality assurance of the data as well as description of metadata and using tools to prepare data packages for long term archiving. It will be an exemplary model for other institutions working with similar data. The development of this workflow is closely intertwined with the educational curriculum at the Institut für Meteorologie. Designing modules to run quality checks for meteorological time series of data measured every minute and preparing metadata are tasks in actual bachelor theses. Students will also test the usability of the generated working environment. Based on these experiences a practical guideline for integrating research data management in curricula will be one of the results of this project, for postgraduates as well as for younger students.

    This X-band image of the volcano Kilauea was taken on October 4, 1994, by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar. The area shown is about 9 kilometers by 13 kilometers (5.5 miles by 8 miles) and is centered at about 19.58 degrees north latitude and 155.55 degrees west longitude. This image and a similar image taken during the first flight of the radar instrument on April 13, 1994 were combined to produce the topographic information by means of an interferometric process. This is a process by which radar data acquired on different passes of the space shuttle is overlaid to obtain elevation information. Three additional images are provided showing an overlay of radar data with interferometric fringes; a three-dimensional image based on altitude lines; and, finally, a topographic view of the region. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X-band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing.

    This is a C-band, VV polarization radar image of the Namib desert in southern Namibia, near the coast of South West Africa. The image is centered at about 25 degrees South latitude, 15.5 degrees East longitude. This image was one of the first acquired by the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR-C/X-SAR) when it was taken on orbit 4 from the shuttle Endeavour on April 9, 1994. The area shown is approximately 78 kilometers by 20 kilometers. The dominant features in the image are complex sand dune patterns formed by the prevailing winds in this part of the Namib desert. The Namib desert is an extremely dry area formed largely because of the influence of the cold Benguela ocean current that flows northward along the coast of Namibia. The bright areas at the bottom of the image are exposed outcrops of Precambrian rocks. This extremely barren area is a region rich in diamonds that through the centuries have washed down from the mountains. The town of Luderitz is located just to the south of the area shown.

North is toward the top left corner of the image. The Kaitak Airport runway on Kowloon Peninsula (center right of image) was built on reclaimed land and extends almost 3 kilometers (nearly 2 miles) into Victoria Harbor. To the south of the harbor lies the island of Hong Kong. The bright areas around the harbor are the major residential and business districts. Housing more than six million residents, Hong Kong is the most densely populated area in the world. The large number of objects visible in the harbor and surrounding waters are a variety of sea-going vessels, anchored in one of the busiest seaports in the Far East.

    Caves formed by rising sulfuric waters have been described from all over the world in a wide variety of climate settings, from arid regions to mid-latitude and alpine areas. H2S is generally formed at depth by reduction of sulfates in the presence of hydrocarbons and is transported in solution through the deep aquifers. In tectonically disturbed areas major fractures eventually allow these H2S-bearing fluids to rise to the surface where oxidation processes can become active producing sulfuric acid. This extremely strong acid reacts with the carbonate bedrock creating caves, some of which are among the largest and most spectacular in the world. Production of sulfuric acid mostly occurs at or close to the water table but also in subaerial conditions in moisture films and droplets in the cave environment. These caves are generated at or immediately above the water table, where condensation-corrosion processes are dominant, creating a set of characteristic meso- and micromorphologies. Due to their close connection to the base level, these caves can also precisely record past hydrological and geomorphological settings. Certain authigenic cave minerals, produced during the sulfuric acid speleogenesis (SAS) phase, allow determination of the exact timing of speleogenesis. This paper deals with the morphological, geochemical and mineralogical description of four very typical sulfuric acid water table caves in Europe: the Grotte du Chat in the southern French Alps, the Acqua Fitusa Cave in Sicily (Italy), and the Bad Deutsch Altenburg and Kraushöhle caves in Austria.

    Time dynamics of isolated many-body quantum systems has long been an elusive subject, perhaps most urgently needed in the foundations of quantum statistical mechanics. In generic systems, one expects the nonequilibrium dynamics to lead to thermalization: a relaxation to states where the values of macroscopic quantities are stationary, universal with respect to widely differing initial conditions, and predictable through the time-tested recipe of statistical mechanics. The relaxation mechanism is not obvious, however; dynamical chaos cannot play the key role as it does in classical systems since quantum evolution is linear. Here we demonstrateootnotetextM. Rigol, V. Dunjko, and M. Olshanii, to appear in Nature (2008), using the results of an ab initio numerical experiment with 5 hard-core bosons moving in a 5x5 lattice, that in quantum systems thermalization happens not in course of time evolution but instead at the level of individual eigenstates, as first proposed by DeutschootnotetextJ.

    2004-09-01

    Deutsche Bahn (German Railways) requires its suppliers to deliver concrete sleepers with high precision dimensions for critical sections. To meet these demands suppliers have to continuously monitor the production process. Critical dimensions are the track width and the widths of both rail supporting planes. Also their orientation must not exceed given tolerances. That demands measurements with a precision of 0.2 mm or better. The contactless measurement system developed uses the triangulation approach based on laser plane projection. It consists of two CCD-cameras and four lasers projecting planes under 45° each. A third camera serves for the recognition of the mould numbers. Software detects if a sleeper is in a measuring position, the camera images are frozen and the measurements are done using line approximation and subpixel accuracy. Additionally the measurement of the positions of peg holes is integrated, these data serve for the control of a screw-in robot. The system is added to the running production line in a harsh industrial environment. It works fully automatically. All measured data are transferred to the production monitoring for evaluation and archiving. The system has been working now for two years, more than half a million sleepers have been reliably monitored.

    The utilization of fermentation media derived from waste and by-product streams from biodiesel and confectionery industries could lead to highly efficient production of bacterial cellulose. Batch fermentations with the bacterial strain Komagataeibacter sucrofermentans DSM (Deutsche Sammlung von Mikroorganismen) 15973 were initially carried out in synthetic media using commercial sugars and crude glycerol. The highest bacterial cellulose concentration was achieved when crude glycerol (3.2 g/L) and commercial sucrose (4.9 g/L) were used. The combination of crude glycerol and sunflower meal hydrolysates as the sole fermentation media resulted in bacterial cellulose production of 13.3 g/L. Similar results (13 g/L) were obtained when flour-rich hydrolysates produced from confectionery industry waste streams were used. The properties of bacterial celluloses developed when different fermentation media were used showed water holding capacities of 102-138 g · water/g · dry bacterial cellulose, viscosities of 4.7-9.3 dL/g, degree of polymerization of 1889.1-2672.8, stress at break of 72.3-139.5 MPa and Young's modulus of 0.97-1.64 GPa. This study demonstrated that by-product streams from the biodiesel industry and waste streams from confectionery industries could be used as the sole sources of nutrients for the production of bacterial cellulose with similar properties as those produced with commercial sources of nutrients.

    The Deutsche Forschungsanstalt für Psychiatrie (DFA, German Institute for Psychiatric Research) in Munich was founded in 1917 bel Emil Kraepelin. For a long time it was the only institution in Germany entirely devoted to psychiatric research. Because of its strictly science-oriented and multidisciplinary approach it also became a model for institutions elsewhere. Kraepelin's ideas have certainly had a strong influence on psychiatry in the twentieth century. The fascinating and instructive history of the DFA reflects the central issues and determinants of psychiatric research. First, talented individuals are needed to conduct such research, and there was no lack in this regard. Second, the various topics chosen are dependent on the available methods and resources. And finally, the issues addressed and the ethical standards of the researchers are heavily dependent on the zeitgeist, as is evident in the three epochs of research at the DFA, from 1917 to 1933, from 1933 to 1945, and from the postwar period to the present. With the introduction of molecular biology and neuroimaging techniques into psychiatric research a change in paradigm took place and a new phase of the current epoch began.

    A strain of Lactobacillus plantarum, DSMZ 12028 (Deutsch Sammlung von Mikroorganismen und Zellkulturen), isolated from a Portuguese dry fermented sausage, "chouriço", was found to produce true lipase, producing free fatty acids from triolein (olive oil). This enzymatic activity was found in whole cells, but was negligible in comparison to lipolytic activity in culture supernatant. Therefore, only extracellular activity was studied. The effect of pH, temperature and glucose concentration on extracellular lipase production was studied in continuously stirred tank reactors, the first time this technology has been used to study the production of this enzyme in lactobacilli. Maximum lipase production was achieved at a pH of 5.5 and 30 degrees C and was kept at a significant level over a wide range of dilution rates (0.05-0.4 h-1); the production of lipase was still significant for low pH values, temperature and glucose concentration, conditions that are close to the ones present during chouriço ripening. The effect of glucose concentration was also studied in a batch system. The control of lipase production was found to be related both to glucose concentration in the medium and to the growth rate/dilution rate. Glucose concentration was found to be important for fast lipase production, although it did not influence the maximum lipase activity reached in a batch culture.

    The Electric Fuel Limited (EFL) zinc-air refuelable battery system will be tested over the next two years in a number of electric vehicle demonstration projects, the largest of which is an $18-million, 64-vehicle, two-year test sponsored chiefly by Deutsche Post AG (the German Post Corporation). The German field test is the largest-ever EV fleet test of a single advanced-battery technology. It also represents a marked departure from other EV test and demonstration programs, in that it is being sponsored not by government or electric utility interests, but by large fleet operators committed to shifting significant proportions of their vehicles to electric over the next 5--10 years. The Electric Fuel battery has specific energy of 200 Wh/kg, an achievement that allows electric vehicles to go as far on a charge as conventionally fueled vehicles go on a tank of gasoline. Fast, convenient refueling eliminates the need for lengthy electrical recharging, and clean, centralized zinc regeneration plants ensure the most efficient and environment-friendly use of energy resources.

  3. Collective oscillations and coupled modes in confined microfluidic droplet arrays

    Schiller, Ulf D.; Fleury, Jean-Baptiste; Seemann, Ralf; Gompper, Gerhard

    Microfluidic droplets have a wide range of applications ranging from analytic assays in cellular biology to controlled mixing in chemical engineering. Ensembles of microfluidic droplets are interesting model systems for non-equilibrium many-body phenomena. When flowing in a microchannel, trains of droplets can form microfluidic crystals whose dynamics are governed by long-range hydrodynamic interactions and boundary effects. In this contribution, excitation mechanisms for collective waves in dense and confined microfluidic droplet arrays are investigated by experiments and computer simulations. We demonstrate that distinct modes can be excited by creating specific `defect' patterns in flowing droplet trains. While longitudinal modes exhibit a short-lived cascade of pairs of laterally displacing droplets, transversely excited modes form propagating waves that behave like microfluidic phonons. We show that the confinement induces a coupling between longitudinal and transverse modes. We also investigate the life time of the collective oscillations and discuss possible mechanisms for the onset of instabilities. Our results demonstrate that microfluidic phonons can exhibit effects beyond the linear theory, which can be studied particularly well in dense and confined systems.

    This paper describes a new project of the Institute for Geoinformatics and Remote Sensing, funded by the German Federal Foundation for the Environment (DBU, Deutsche Bundesstiftung Umwelt www.dbu.de). The goal of this project is to develop a mobile zoo information system for Pocket PCs and Smart phones. Visitors of the zoo will be able to use their own mobile devices or use Pocket PCs, which could be borrowed from the zoo to navigate around the zoo's facilities. The system will also provide additional multimedia based information such as audio-based material, animal video clips, and maps of their natural habitat. People could have access to the project at the zoo via wireless local area network or by downloading the necessary files using a home internet connection. Our software environment consists of proprietary and non-proprietary software solutions in order to make it as flexible as possible. Our first prototype was developed with Visual Studio 2003 and Visual Basic.Net.

    Doppler ultrasound scanning is the first line investigation for quantifying the internal carotid artery stenosis. Nevertheless, the lack of internationally accepted ultrasound criteria for describing the degree of stenosis has contributed to the different and confusing measurements ranges. The use of two different angiographic methods, the North American Symptomatic Carotid Endoarterectomy Study and the European Carotid Surgery Trial was probably the major initial source of confusion in deriving valid and reliable duplex ultrasound criteria worldwide. The consensus proposed in 2003 by the Society of Radiologists in Ultrasound has been a great attempt to create a conformity document, establishing grey scale and Doppler criteria in considering the different degrees of stenosis. According to this attempt, in 2010, the multi-parametric Deutsche Gesellschaft für Ultraschall in der Medizin ultrasound criteria have been proposed with a precise differentiation between main and additional criteria and depicted a different peak systolic velocity (PSV) threshold. In 2012, these criteria have been implemented, focusing on the multi-parametric approach, re-defining the PSV values and clearly introducing the concept of PSV average. Despite these attempts, a wide range of practice patterns still exists, with consistent disparities in patients' care. This paper collects these previous experiences and summarizes their strengths and weaknesses, to give a contribution in the carotid artery stenosis grading standardization using ultrasonic methods. Carotid ultrasound as the only diagnostic tool for the selection of patients for carotid surgery or stenting will be possible only with internationally accepted criteria.

    In 1928 Albert Schweitzer planned to found a second private hospital comparable to that in Lambaréné (Gabon), this time in Somalia, the former German colony Deutsch-Ostafrika. At Lambaréné there were French missionaries nearby whereas in Somalia Schweitzer intended to cooperate with protestant missionaries from Berlin. For that reason informative talks with responsible members of the Berliner Missionsgesellschaft and negotiations about basic conditions started in 1928 continuing until 1936. As the correspondence is still preserved in the society's archives at East Berlin an ample documentation about the whole procedure can be published here for the first time. It demonstrates different aspects of Schweitzer's unique personality, his social aims, contrary and corresponding views of his German partners, flashlights on the organizing support by intimate friends, the way of collecting financial support, etc. Collaboration was assuming its concrete form, when, all of a sudden, the growing monetary inflation and deteriorating economic situation forced Schweitzer to desist of realizing his East-African dream in order to save Lambaréné.

    This paper is an outline of a proposed initiative on intersectoral collaboration in health promotion--collaboration between health, tourist, cultural and entertainment sectors to provide a powerful mass educational experience about the human mind and body. There has been a recent rise in interest in using the technology of museums, science centres, exploratories and theme parks for the promotion of health. This revival is shown to have a historical tradition in the health education museum started in this century in Europe 75 years ago at the Deutsches Hygiene Museum and then spreading to the USA. The proposed Body, Mind, City Museum planned for Liverpool acts as a future model for a new type of health Museum; a mixture of science exploratorium and a Walt Disney-style them park. It is intended that "hand-on" exhibits using interactive video, computers, games and experiences will be used to test people's own capacities or to describe biological functions or processes. This will be combined with park rides and simulations with their inherent appeal of fun, movement and surprise, for example the ride through the blood vessels and the "walk-through brain". This type of venture has a number of special features and advantages; it is truly intersectoral, it may be self-financing, and it can provide a mass audience with a powerful individual experience.

    The Raptor kJ class 1053 nm Nd:Glass laser in the Phoenix laser laboratory at University of California, Los Angeles, is used to ablate a dense debris plasma from a graphite or plastic target embedded in a tenuous, uniform, and quiescent ambient magnetized plasma in the Large Plasma Device (LAPD) which provides a peak plasma density of ni ~ 1013 cm-3. Its background magnetic field can vary between 200 and 1200 G. Debris ions from laser produced plasma expand out conically with super-Alfvénic speed (MA ~ 2) and expel the background magnetic field and ambient ions to form a diamagnetic bubble. The debris plasma interacts with the ambient plasma and the magnetic field and acts as a piston which can create collisionless shocks. Flute-type instabilities, which are probably large Larmor radius Rayleigh Taylor instabilities or lower hybrid drift instabilities, are developed at the bubble edge and also observed in the experiment. The amplitude and wavelength dependence of the instabilities, which might be a strong function of debris to ambient mass to charge ratio, is studied and the experimental results are compared to the two dimensional hybrid simulations. the Deutsche Forschungsgemeinschaft in the framework of the Excellence Initiative Darmstadt Graduate School of Energy Science and Engineering (GSC1070).

    Recent Deutsche Gesellschaft für Rheumatologie (DGRh, German Society of Rheumatology) guidelines emphasized the significance of coordinated multidisciplinary care and rehabilitation of patients with inflammatory rheumatic diseases. Nationwide data from the German pension insurance funds showed that inpatient rehabilitation due to rheumatoid arthritis (RA) varied by a factor of 2.6 between the different German states. From 2000 to 2012 rehabilitation measures were reduced by one third, most significantly in men with ankylosing spondylitis (AS). Rehabilitation measures because of RA or AS were provided up to 14 times more frequently by the German statutory pension insurance scheme compared with a large compulsory health insurance which is responsible for rehabilitation measures after retirement. In rehabilitation centers with high numbers of patients with inflammatory rheumatic diseases, higher structural and process quality were demonstrated. In 2011 a total of 40 % of RA patients in the national database of the collaborative arthritis centers showed medium or severe functional limitations. Among these disabled RA patients inpatient rehabilitation was reduced by about 50 % between 1995 and 2011. Out of all RA patients from outpatient rheumatology care with severe functional limitations 38 % had no functional restoration therapy within the previous 12 months with a high variation between rheumatologists. Experiences from other European countries may inspire German rheumatologists and other involved health professionals to initiate a wider range of rehabilitative interventions in the future.

    We discuss the nonequilibrium dynamics in two interaction quantum quenches in the one-dimensional Fermi-Hubbard model. First, we study the decay of the Néel state as a function of interaction strength. We observe a fast charge dynamics over which double occupancies are built up, while the long-time decay of the staggered moment is controlled by spin excitations, corroborated by the analysis of the entanglement dynamics. Second, we investigate the formation of Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) correlations in a spin-imbalanced system in quenches from the noninteracting case to attractive interactions. Even though the quench puts the system at a finite energy density, peaks at the characteristic FFLO quasimomenta are visible in the quasi-momentum distribution function, albeit with an exponential decay of s-wave pairing correlations. We also discuss the imprinting of FFLO correlations onto repulsively bound pairs and their rapid decay in ramps. Supported by the DFG (Deutsche Forschungsgemeinschaft) via FOR 1807.

    The measurement of atmospheric ice nucleating particles (INP) is still challenging. In the absence of easily applicable INP standards the intercomparison of different methods during collaborative laboratory and field workshops is a valuable tool that can shine light on the performance of individual methods for the measurement of INP [1]. FIN-2 was conducted in March 2015 at the AIDA facility in Karlsruhe as an intercomparison of mobile instruments for measuring INP [2]. FIN-3 was a field campaign at the Desert Research Institutes Storm Peak Laboratory in Colorado in September 2015 [3]. The FRankfurt Ice nucleation Deposition freezinG Experiment (FRIDGE) participated in both experiments. FRIDGE measures ice nucleating particles by electrostatic precipitation of aerosol particles onto Si-wafers in a collection unit, followed by activation, growth, and optical detection of ice crystals on the substrate in an isostatic diffusion chamber [4,5]. We will present and discuss results of our measurements of deposition/condensation INP and of immersion INP with FRIDGE during FIN-2 and FIN-3.

    An essential prerequisite for integrating disabled persons is their mobility. The special transport approach, both in terms of handling capacity and cost involved, is increasingly turning out to be unable to achieve future-oriented solutions in this context. Disabled people wish to use the transport services available to the general public. They therefore demand public transportation policies to provide for their access to the mainstream system, ideally independent of outside assistance. Deutsche Bundesbahn, the German federal railways, in the field of tension between the need to orient its business policies on economic and financial considerations and disabled persons' demands that vehicles and premises be designed in a barrier-free manner, seeks to achieve solutions that are responsive to users' needs and at the same time economically justifiable. On account of the 19th century infrastructure legacy and a wide range of rolling stock in long- and short-distance rail travel, this can however be realized only step by step. The facilities offered to disabled people so far range from free use of short-distance trains to the accessibility-oriented design of coaches for the Intercity Express, the future of the railways in the European rapid transit network. The various services and facilities provided are hoped to foster disabled persons' decision in favour of the environmentally compatible rail mode of travelling.

    Displacement damage (DD) caused by fast neutrons in unbiased Gallium Arsenide (GaAs) light emitting diodes (LED) resulted in a reduction of the light output. On the other hand, a similar type of LED irradiated with gamma rays from a (60)Co source up to a dose level in excess of 1.0 kGy (1.0 x 10(5) rad) was found to show no significant drop of the light emission. This phenomenon was used to develop a low cost passive fluence monitor and kinetic energy released per unit mass dosemeter for accelerator-produced neutrons. These LED-dosemeters were used to assess the integrated fluence of photoneutrons, which were contaminated with a strong bremsstrahlung gamma-background generated by the 730 MeV superconducting electron linac driving the free electron laser in Hamburg (FLASH) at Deutsches Elektronen-Synchrotron. The applications of GaAs LED as a routine neutron fluence monitor and DD precursor for the electronic components located in high-energy accelerator environment are highlighted.

    The work described here revealed the presence of diverse microbial communities located across 19 subsurface sites at the NNSS/NTTR and nearby locations. Overall, the diversity of microorganisms was high for subsurface habitats and variable between sites. As of this writing, preparations are being made to combine the Illumina sequences and 16S rRNA clone libraries with other non-NNSS/NTTR well sites of Southern Nevada Regional Flow System for a publication manuscript describing our very broad landscape scale survey of subsurface microbial diversity. Isolates DRI-13 and DRI-14 remain to be fully characterized and named in accordance with the conventions established by Bergey's Manual of Systematic Bacteriology. In preparation to be published, these microorganisms will be submitted to the American Type Culture Collection (ATCC) and the Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH (DSMZ).It is anticipated that the data resulting from this study in combination with other data sets that will allow us to produce a number of publications that will be impactful to the subsurface microbiology community.

    We report the development of a new tool to determine the origin of quasi-periodic oscillations (QPOs) in accretion disk systems. The technique uses the source energy spectrum and the energy dependence of the QPO fractional amplitude to restrict the location of the emission region of the modulated photons, which are assumed to originate in the inner accretion disk. Both Monte-Carlo and semi-analytical methods are presented. We assume the accretion disk is enshrouded by a slab atmosphere of hot electrons in which unsaturated Compton scattering produces the high-energy spectrum. Properties of the atmosphere, in particular the electron temperature, are assumed functions of radius from the central compact object. We show that our model reproduces the observed energy dependence of the fractional amplitude of the 67 Hz QPO in GRS 1915+105 if the QPO is assumed to originate at a particular region of the inner disk.

    High power laser fields enabled by technologies developed for ground-based gravitational-wave observatories open up new opportunities for fundamental physics studies. One of these options is the search for axions and axion-like particles in a pure laboratory experiment. The axion is a solution to the strong CP-problem and a potential dark matter candidate. The axion has also been proposed as an additional channel to cool stars as well as a potential explanation for the TeV transparency problem. The German-US ALPS collaboration is setting up a light-shining-through-walls (LSW) experiment at DESY. LSW experiments are based on the simple idea that a high power laser field traversing a static magnetic field will transform partly into a relativistic axion field. This axion field will travel through an opaque wall into a second static magnetic field region where it turns partly back into an electromagnetic wave field with the same frequency as the laser. The ALPS collaboration is working towards a large scale LSW experiment at DESY in Hamburg, Germany. I will report on the status of the ALPS experiment.

    A quantum cascade (QC) laser with a dual-wavelength interdigitated cascade is presented. Its active core consists of a stack of active regions and injectors designed for emission at one wavelength (8.0 μm) interleaved with a second stack emitting at a substantially different wavelength (9.5 μm), and the two injectors were designed to either bridge the 8.0 μm active region to the 9.5 μm one, or vice versa. Clear two-wavelength laser action is observed, demonstrating the viability of this approach to achieve multi-wavelength laser emission in the mid-infrared. Aside from providing two-wavelength operation, this laser design can also be used to test the role of charge transport in the injectors, which customarily bridge successive active regions together. We will present early results of this study. The work was partly supported by DARPA/US ARO under contract number DAAD19-00-C-0096. A. S. acknowledges the support of the Deutsche Studienstiftung. T.

    The World Congress of Herpetology (WCH, http://www.worldcongressofherpetology.org/) is a relatively young organization as far as august herpetological societies go. It was formed in 1982, the year of the 25th meeting of the Society for the Study of Amphibians and Reptiles (founded in 1958), which itself is a relative youngster when compared to organizations such as the American Society for Ichthyology and Herpetology (founded in 1913) or Die Deutsche Gesellschaft für Herpetologie und Terrarienkunde e. V. (originally founded in 1918 under a different name). Despite its youth, the WCH has accomplished much during its relatively short existence. Arguably the greatest accomplishment of the WCH was to provide the venue at the first meeting of the Congress, held in 1989 at Canterbury, UK, where numerous amphibian biologists shared tales of enigmatic declines and disappearances of amphibian study species. Undoubtedly these exchanges sparked the formation of the Declining Amphibian Populations Task Force, providing impetus for the establishment of IUCN's Global Amphibian Assessment. This assessment, along with other research, in turn confirmed that amphibians are declining at a global scale and are more threatened than any other vertebrate class comprehensively assessed to date (Houlahan et al., 2000; Stuart et al., 2004).

  20. Assessing the sound quality of a grand piano for different tuning standards

    2003-10-01

    Grand pianos are tuned to a standard frequency of 440 Hz for a4. Eighty years ago, the tuning standard was lower, around 432 Hz. In Germany, a group of music lovers insists that the sound quality of a grand piano when tuned to 432 Hz is much superior to that of the same instrument when tuned to 440 Hz. Therefore, well-controlled psychoacoustic experiments were performed to check the validity of that argument. Using a Welte-Steinway reproduction grand piano of the Deutsches Museum Muenchen, with the exception of the tuning, all other features of the pieces of music used as stimuli could be kept the same. The advantage of using the Welte-Steinway lies in the fact that reproductions of the music of famous (deceased) artists are available, who at their time performed at a lower tuning standard. Recordings of the music played at 432 vs 440 Hz were made on DAT and presented to the subjects via headphones for sound quality evaluation. Psychophysical procedures like semantic differential or preference scaling by ``random access'' that have proven successful for the assessment of sound quality in the context of car interior sounds were used in the experiments.

    The European X-ray Free-Electron laser Facility (XFEL) is going to be built in an international collaboration at the Deutsches Elektronen-Synchrotron (DESY), Germany, and the Technical Design Report was published in 2006. The official project is expected for summer 2007. This new facility will offer photon beams at wavelengths as short as 1 angstrom with highest peak brilliance being more than 100 million times higher than present day synchrotron radiation sources. The radiation has a high degree of transverse coherence and the pulse duration is reduced from {approx}100 picoseconds (typ. for SR light sources) down to the {approx}10 femtosecond time domain. The overall layout of the XFEL will be described. This includes the envisaged operation parameters for the linear accelerator using superconducting TESLA technology. The complete design is based on the actually operated FLASH free-electron laser at DESY. Experience with the operation during first long user runs at wavelengths from 30 to 13 nm will be described in detail.

  2. Are root letters compulsory for lexical access in Semitic languages? The case of masked form-priming in Arabic.

    2014-09-01

    Do Semitic and Indo-European languages differ at a qualitative level? Recently, it has been claimed that lexical space in Semitic languages (e.g., Hebrew, Arabic) is mainly determined by morphological constraints, while lexical space in Indo-European languages is mainly determined by orthographic constraints (Frost, Kugler, Deutsch, & Forster, 2005). One of the key findings supporting the qualitative difference between Semitic and Indo-European languages is the absence of masked form priming in Hebrew/Arabic with productive words. Here we examined whether masked form priming occurs in Arabic words when one of the letters from the productive root is replaced in the prime stimulus by another letter. Results showed a significant masked form priming effect with the lexical decision task in three experiments (including yes/no, go/no-go, and sandwich priming), to a similar degree to that reported in previous research with Indo-European languages. These data support the view that the processing of word forms in Semitic vs. Indo-European languages differs more at a quantitative than at a qualitative level.

  3. Transient Response of a Separated Flow over a Two-Dimensional Wing to a Short Duration Pulse

    A Lorentz force actuator located at the leading edge of a two-dimensional wing at 16 degrees angle of attack was used to introduce short-duration disturbances into a separated flow. The transient response of the separated region at Re = 10,000 was documented using time-resolved PIV measurements. The direction of the Lorentz force was changed between downstream and upstream directed disturbances, and details of the resulting flow field structures and lift measurements were studied. Saturation of the peak lift amplitude occurs as the actuation amplitude is increased from 0.0054 < C μ < 0.21 percent with the pulse duration fixed at 0.1 convective time. The effect of the pulse duration time on the lift response was examined using a fixed pulse amplitude, which showed that saturation occurred when pulse durations exceed 0.5 convective times. Differences in the coherent structures resulting from the upstream/downstream directed actuation were identified using the FTLE method. The initial development of the disturbed shear layer was strongly dependent on the direction of actuation, but the larger-scale separation did not show much difference. The relaxation of the separated region to the original flow state was essentially independent of the direction of actuation.

    Psoriasis vulgaris is a common and chronic inflammatory skin disease which has the potential to significantly reduce the quality of life in severely affected patients. The incidence of psoriasis in Western industrialized countries ranges from 1.5 to 2%. Despite the large variety of treatment options available, patient surveys have revealed insufficient satisfaction with the efficacy of available treatments and a high rate of medication non-compliance. To optimize the treatment of psoriasis in Germany, the Deutsche Dermatologische Gesellschaft and the Berufsverband Deutscher Dermatologen (BVDD) have initiated a project to develop evidence-based guidelines for the management of psoriasis. The guidelines focus on induction therapy in cases of mild, moderate, and severe plaque-type psoriasis in adults. The short version of the guidelines reported here consist of a series of therapeutic recommendations that are based on a systematic literature search and subsequent discussion with experts in the field; they have been approved by a team of dermatology experts. In addition to the therapeutic recommendations provided in this short version, the full version of the guidelines includes information on contraindications, adverse events, drug interactions, practicality, and costs as well as detailed information on how best to apply the treatments described (for full version, please see Nast et al., JDDG, Suppl 2:S1–S126, 2006; or http://www.psoriasis-leitlinie.de).

    We present for the first time the Raman microspectroscopic identification and characterization of individual airborne volcanic ash (VA) particles. The particles were collected in April/May 2010 during research aircraft flights, which were performed by Deutsches Zentrum für Luft- und Raumfahrt in the airspace near the Eyjafjallajökull volcano eruption and over Europe (between Iceland and Southern Germany). In addition, aerosol particles were sampled by an Electrical Low Pressure Impactor in Munich, Germany. As references for the Raman analysis, we used the spectra of VA collected at the ground near the place of eruption, of mineral basaltic rock, and of different minerals from a database. We found significant differences in the spectra of VA and other aerosol particles (e.g., soot, nitrates, sulfates, and clay minerals), which allowed us to identify VA among other atmospheric particulate matter. Furthermore, while the airborne VA shows a characteristic Raman pattern (with broad band from ca. 200 to ca. 700 cm(-1) typical for SiO₂ glasses and additional bands of ferric minerals), the differences between the spectra of aged and fresh particles were observed, suggesting differences in their chemical composition and/or structure. We also analyzed similarities between Eyjafjallajökull VA particles collected at different sampling sites and compared the particles with a large variety of glassy and crystalline minerals. This was done by applying cluster analysis, in order to get information on the composition and structure of volcanic ash. PMID:24121468

  6. Explaining the freemartin: Tandler and Keller vs. Lillie and the question of priority.

    PubMed

    The correct explanation for the freemartin phenotype in the female twin of a female-male pair in cattle was first reported by Tandler and Keller (1911. Deutsche Tierärzt Wochenschr 19:148-149). This same explanation for the freemartin was independently discovered by Lillie (1916. Science 43:611-613). Today both set of scientists are given credit for this discovery; it is the basis for much of the subsequent work on the developmental basis for sex differentiation in vertebrates. Even though Lillie published after Keller and Tandler, he gets credit for this discovery because: (1) Keller and Tandler published in a veterinary journal and as a consequence their work was not disseminated as broadly throughout the larger scientific community; this problem was compounded by the fact that their definitive 1916 paper was published under wartime conditions during World War I, and (2) Lillie was an influential scientist with a group of graduate students who could elaborate on and extend his work; they published a number of papers on the freemartin. At some point while Lillie was doing his initial work on the freemartin he may have become aware that Keller and Tandler were also working on the freemartin problem; this information may have shaped his decision on when to publish.

  7. Extrasolar Giant Planets: Masses and Luminosities from In-situ Formation Theories

    Their\\footnoteThis work has been supported by the Oster\\-reichischer Fonds zur Forderung der wissenschaftlichen Forschung (FWF) under project numbers S-7305--AST, S-7307--AST and the Deutsche Forschungsgemeinschaft (DFG), SFB 359 (key research project of the german national science foundation on `Reactive flows, diffusion and transport'). expected luminosities make young giant planets favorable for the first direct detection of an extrasolar planet. The giant planet formation process is relatively slow with expected formation times ranging from comparable to the star formation timescale up to the nebula lifetime, depending on the formation theory. Therefore quantitative models of giant planet formation have to be considered when estimating young giant planet properties at pre-main sequence stellar ages. This is especially important for free-floating giant planet candidates where planetary nature is inferred from luminosities, without independent mass determinations. I will discuss observables of young- and proto-giant planets as they follow from the disk-instability and nucleated-instability hypothesis, respectively. The luminosity exceeds 10(-4) solar luminosities, even for a Saturn-mass protoplanet, during the brief, 30000 year period around maximum accretion. Luminosity maxima of giant planets occur at ages of 1-10 Myr, depending on the details of the formation process. To infer planetary nature in a young population, the properties of young planets have to be compared to those of proto brown dwarfs, as they follow from the respective formation theories.

    The first European remote sensing satellite ERS-1 will be launched by the European Space Agency (ESA) in 1989. The expected lifetime is two to three years. The spacecraft sensors will primarily support ocean investigations and to a limited extent also land applications. Prime sensor is the Active Microwave Instrumentation (AMI) operating in C-Band either as Synthetic Aperture Radar (SAR) or as Wave-Scatterometer and simultaneously as Wind-Scatterometer. In Europe there will be two distinct types of processing for ERS-1 SAR data, Fast Delivery Processing and Precision Processing. Fast Delivery Proceessing will be carried out at the ground stations and up to three Fast Delivery products per pass will be delivered to end users via satellite within three hours after data acquisition. Precision Processing will be carried out in delayed time and products will not be generated until several days or weeks after data acquisition. However, a wide range of products will be generated by several Processing and Archiving Facilities (PAF) in a joint effort coordinated by ESA. The German Remote Sensing Data Center (Deutsches Fernerkundungsdatenzentrum DFD) will develop and operate one of these facilities. The related activities include the acquisition, processing and evaluation of such data for scientific, public and commercial users. Based on this experience the German Remote Sensing Data Center is presently performing a Phase-B study regarding the development of a SAR processor for ERS-1. The conceptual design of this processing facility is briefly outlined.

    2015-09-01

    We present an industry-relevant, large-scale, ultra-high vacuum (UHV) magnetron sputtering and cathodic arc deposition system purposefully designed for time-resolved in situ thin film deposition/annealing studies using high-energy (>50 keV), high photon flux (>10(12) ph/s) synchrotron radiation. The high photon flux, combined with a fast-acquisition-time (<1 s) two-dimensional (2D) detector, permits time-resolved in situ structural analysis of thin film formation processes. The high-energy synchrotron-radiation based x-rays result in small scattering angles (<11°), allowing large areas of reciprocal space to be imaged with a 2D detector. The system has been designed for use on the 1-tonne, ultra-high load, high-resolution hexapod at the P07 High Energy Materials Science beamline at PETRA III at the Deutsches Elektronen-Synchrotron in Hamburg, Germany. The deposition system includes standard features of a typical UHV deposition system plus a range of special features suited for synchrotron radiation studies and industry-relevant processes. We openly encourage the materials research community to contact us for collaborative opportunities using this unique and versatile scientific instrument.

  10. International Standardization of the Clinical Dosimetry of Beta Radiation Brachytherapy Sources: Progress of an ISO Standard

    2006-03-01

    In 2004 a new work item proposal (NWIP) was accepted by the International Organization for Standardization (ISO) Technical Committee 85 (TC85 -- Nuclear Energy), Subcommittee 2 (Radiation Protection) for the development of a standard for the clinical dosimetry of beta radiation sources used for brachytherapy. To develop this standard, a new Working Group (WG 22 - Ionizing Radiation Dosimetry and Protocols in Medical Applications) was formed. The standard is based on the work of an ad-hoc working group initiated by the Dosimetry task group of the Deutsches Insitiut für Normung (DIN). Initially the work was geared mainly towards the needs of intravascular brachytherapy, but with the decline of this application, more focus has been placed on the challenges of accurate dosimetry for the concave eye plaques used to treat ocular melanoma. Guidance is given for dosimetry formalisms, reference data to be used, calibrations, measurement methods, modeling, uncertainty determinations, treatment planning and reporting, and clinical quality control. The document is currently undergoing review by the ISO member bodies for acceptance as a Committee Draft (CD) with publication of the final standard expected by 2007. There are opportunities for other ISO standards for medical dosimetry within the framework of WG22.

    Deutsche Bahn AG has developed and continuously improved over the last decade a system called "Specially Monitored Track". It is based on the fact that the noise emission from railways can be reduced by rail grinding and has been confirmed officially in 1998 by the German Federal Railway Office (EBA) as a noise reduction system with an effectiveness of -3 dB(A). Meanwhile almost 1000 km of DB's network are specially monitored. In order to comply with this legislation, intensive grinding and monitoring is required. The latter is done by a dedicated monitoring car and supplemented by roughness measurements using a modified roughness-measuring device in connection with a newly developed algorithm for data analysis, enabling a prediction of the noise emission on the basis of roughness measurements. Future developments will aim at increasing the performance of the system "Specially Monitored Track". This will particularly include grinding at high working speeds ("High Speed Grinding") with two targets: (1) reducing costs for rail grinding and (2) merging rail grinding for acoustic reasons with grinding for regular track maintenance.

  12. Experimental Implementation of High-Fidelity Single-Qubit Gates for Two-Electron Spin Qubits in GaAs

    High fidelity gate operations for manipulating individual and multiple qubits in the presence of decoherence are a prerequisite for fault-tolerant quantum information processing. However, the control methods used in earlier experiments on GaAs two-electron spin qubits are based on unrealistic approximations which preclude reaching the required fidelities. An attractive remedy is to use control pulses found in numerical simulations that minimize the infidelity from decoherence and take the experimentally important imperfections and constraints into account. We show that the experimental implementation of these numerically optimized control pulses is possible by using a self-consistent calibration routine we proposed earlier. In our experiment this calibration routine succeeds in removing systematic gate errors to a high degree without increasing the pulses' decoherence. We extract the Bloch sphere trajectories of the resulting gate sequences using self-consistent state tomography and find good agreement with the theoretically predicted trajectories. Furthermore, we prepare different states using these gates and determine their fidelities. Alfried Krupp von Bohlen und Halbach - Foundation, Deutsche Telekom Foundation.

    An experimental study is reported on the electron-impact total ionization cross sections (TICSs) of CCl4, CCl3F, CCl2F2, and CClF3 molecules. The kinetic energy of the colliding electrons was in the 10-85 eV range. TICSs were obtained as the sum of the partial ionization cross sections of all fragment ions, measured and identified in a linear double focusing time-of-flight mass spectrometer. The resulting TICS profiles—as a function of the electron-impact energy—have been compared both with those computed by ab initio and (semi)empirical methods and with the available experimental data. The computational methods used include the binary-encounter-Bethe (BEB) modified to include atoms with principal quantum numbers n⩾3, the Deutsch and Märk (DM) formalism, and the modified additivity rule (MAR). It is concluded that both modified BEB and DM methods fit the experimental TICS for (CF4), CClF3, CCl2F2, CCl3F, and CCl4 to a high accuracy, in contrast with the poor accord of the MAR method. A discussion on the factors influencing the discrepancies of the fittings is presented.

  15. Variational Principles, Occam Razor and Simplicity Paradox

    NASA Astrophysics Data System (ADS)

    Berezin, Alexander A.

    2004-05-01

    Variational minimum principles (VMP) refer to energy (statics, Thomson and Earnshaw theorems in electrostatics), action (Maupertuis, Euler, Lagrange, Hamilton), light (Fermat), quantum paths (Feynman), etc. Historically, VMP appeal to some economy in nature, similarly to Occam Razor Parsimony (ORP) principle. Version of ORP are "best world" (Leibniz), Panglossianism (Voltaire), and "most interesting world" (Dyson). Conceptually, VMP exemplify curious fact that infinite set is often simpler than its subsets (e.g., set of all integers is simpler than set of primes). Algorithmically very simple number 0.1234567... (Champernowne constant) contains Library of Babel of "all books" (Borges) and codes (infinitely many times) everything countably possible. Likewise, full Megaverse (Everett, Deutsch, Guth, Linde) is simpler than our specific ("Big Bang") universe. Dynamically, VMP imply memory effects akin to hysteresis. Similar ideas are "water memory" (Benveniste, Josephson) and isotopic biology (Berezin). Paradoxically, while ORP calls for economy (simplicity), unfolding of ORP in VMP seemingly works in the opposite direction allowing for complexity emergence (e.g., symmetry breaking in Jahn-Teller effect). Metaphysical extrapolation of this complimentarity may lead to "it-from-bit" (Wheeler) reflection of why there is something rather than nothing.

    PubMed

    Sammer, Christian

    2015-01-01

    Using the example of smoking, this article scrutinizes the notions of order, educational conduct and images of subjects in the health education of both German states between 1949 and the mid 70s. Drawing on archival sources, publications and educational media from both health ministries, the Deutsches Hygiene-Museum and the Bundeszentrale für gesundheitliche Aufklärung I reconstruct the organizational, conceptual and medial shift of health education from "citizenship" to a technology of communication and public relation, needing "scientification" in the 1960s. New epidemiological evidence fostered the belief in an efficacious prevention of manly coded and with smoking associated cardio-vascular diseases by forming healthy behavior. This went hand in hand with the increase of state responsibility for the health of its citizens and the import of new knowledge stemming from social research and new methodological expertise from advertising. At the same time the ideal of a comprehensible citizen shifted into a "socialist personality" that was to be shaped by a hierarchical and consistent education in the German Democratic Republic. In the Federal Republic of Germany the general principle of the self-determined citizen unfolded the antagonism of health education between individual emancipation and imposition.

    Laser-based plasma spectroscopic techniques have been used with great success to determine the line shapes of atomic transitions in plasmas, study the population kinetics of atomic systems embedded in plasmas, and look at the redistribution of radiation. However, the possibilities for optical lasers end for plasmas with n{sub e}>10{sup 22}cm{sup -3} as light propagation is severely altered by the plasma. The construction of the Tesla Test Facility(TTF) at DESY(Deutsche Elektronen-Synchrotron), a short pulse tunable free electron laser in the vacuum-ultraviolet and soft X-ray regime (VUV FEL), based on the SASE(self amplified spontaneous emission) process, will provide a major advance in the capability for dense plasma-related research. This source will provide 10{sup 13} photons in a 200 fs duration pulse that is tunable from {approx} 6nm to 100nm. Since an VUV FEL will not have the limitation associated with optical lasers the entire field of high density plasmas kinetics in laser produced plasma will then be available to study with tunable source. Thus, one will be able to use this and other FEL x-ray sources to pump individual transitions creating enhanced population in the excited states that can easily be monitored. We show two case studies illuminating different aspects of plasma spectroscopy.

  18. Vacuum Fluctuations, Cosmogenesis and Prime Number Gaps

    NASA Astrophysics Data System (ADS)

    Berezin, Alexander A.

    2002-10-01

    Starting from E.Tryon (1973), idea of cosmogenesis through quantum tunnelling "from nothing" became popular. Both complimentary streams of it, inflationary models (Guth, Linde) and quantum parallelism (Everett, Deutsch), require some starting point as, e.g., concretisation of Leibnitz Principle (Omnibus ex nihil decendis sufficit unum). This leads to propositional conjecture (axiom?) that (meta)physical "Platonic Pressure" of infinitude of numbers and Cantor "alephs" becomes an engine for self-generation of physical universe directly out of mathematics: inexhaustibility of Number Theory (NT) drives cosmogenesis. While physics in other quantum branches of inflating universe (Megaverse) can be (arbitrary) different from ours, NT is not (it is unique, absolute, immutable and infinitely resourceful). Energy-time uncertainty principle (UP) allows indefinite lifetime provided we start from total zero energy. Analogue of UP in NT is theorem by H.Maier (1981) stating the existence of arbitrary long trails of isolated primes such that each next gap is arbitrary greater than average gap (logN). On physical level these arbitrary large deviations from Prime Number Theorem translate into permissiveness of (arbitrary) large quantum fluctuations.

  19. The German IVF Register as an Instrument to Document Assisted Reproductive Technologies

    2016-01-01

    The German IVF Register (Deutsches IVF-Register [D.I.R]) has been collecting and publishing data on the use of IVF and related methods in Germany since 1982. It is the only institution which provides information for all of Germany on procedures and their success rates. For this reason it plays an important role in the provision of information to the public, to patients, political decision-makers and the scientific community. However, the register does not have the data of all centers offering treatment in Germany nor does it have complete datasets on all reported treatments. The register accepts retrospective data entries, it does not publish the success rates of individual centers and up until 2015 it did not provide a summary of information which was suitable for non-specialists. The D.I.R has been the focus of criticism in the past. Even today, the information it provides to the scientific community, the public, political decision-makers and potential patients on the outcomes of assisted reproduction is insufficient. The documentation of reproductive medicine procedures in other countries is much more meaningful. PMID:27365538

    Semianalytical approximate solutions of the spatial distribution of electric field and electron and ion densities have been obtained by solving Poisson's equations and the continuity equations for the charged species along the Laplacian field lines. The need to iterate for the correct value of space charge on the corona electrode has been eliminated by using the corona current distribution over the grounded plane derived by Deutsch, which predicts a cos m θ law similar to Warburg's law. Based on the results of the approximated model, a parametric study of the influence of gas pressure, the corona wire radius, and the inter-electrode wire-plate separation has been carried out. Also, the approximate solutions of the electron number density has been combined with a simplified plasma chemistry model in order to compute the ozone density generated by the corona discharge in the presence of a gas flow.

    After Freud proposed in 1918 the creation of "institutions or out-patient clinics [where] treatment will be free," Max Eitingon, Ernst Simmel, and other progressive psychoanalysts founded the Berlin Poliklinik, a free outpatient clinic. Guided by Weimar Republic principles of "radical functionalism," the Poliklinik and its companion inpatient service, the Schloss Tegel Sanatorium, pioneered treatment and training methodologies still used--and still debated--today. Their funding strategies, statistics, and approaches to clinical problems like length of treatment tell the history of an innovative psychoanalytic institute where men and women were generally treated in equal numbers and patients (ranging in occupational status from unemployed to professional) of all ages were treated free. Franz Alexander, Karl Abraham, Theresa Benedek, Paul Federn, Otto Fenichel, Edith Jacobson, Karen Horney, Erich Fromm, Helene Deutsch, Hanns Sachs, Sándor Radó, Hermine von Hug-Hellmuth, Wilhelm Reich, Annie Reich, and Melanie Klein all worked at the Poliklinik, and from there initiated decades of original clinical theory, practice, and education.

  2. Are root letters compulsory for lexical access in Semitic languages? The case of masked form-priming in Arabic.

    PubMed

    Perea, Manuel; Mallouh, Reem Abu; Carreiras, Manuel

    2014-09-01

    Do Semitic and Indo-European languages differ at a qualitative level? Recently, it has been claimed that lexical space in Semitic languages (e.g., Hebrew, Arabic) is mainly determined by morphological constraints, while lexical space in Indo-European languages is mainly determined by orthographic constraints (Frost, Kugler, Deutsch, & Forster, 2005). One of the key findings supporting the qualitative difference between Semitic and Indo-European languages is the absence of masked form priming in Hebrew/Arabic with productive words. Here we examined whether masked form priming occurs in Arabic words when one of the letters from the productive root is replaced in the prime stimulus by another letter. Results showed a significant masked form priming effect with the lexical decision task in three experiments (including yes/no, go/no-go, and sandwich priming), to a similar degree to that reported in previous research with Indo-European languages. These data support the view that the processing of word forms in Semitic vs. Indo-European languages differs more at a quantitative than at a qualitative level. PMID:24954309

    This paper summarizes work performed under a collaborative research effort between the National Aeronautics and Space Administration (NASA) and the German Aerospace Research Establishment (DLR, Deutsche Forschungsanstalt fur Luft- und Raumfahrt). The objective is to develop and demonstrate system identification technology for future large space structures. Recent experiences using the Eigensystem Realization Algorithm (ERA), for modal identification of Mini-Mast, are reported. Mini-Mast is a 20 m long deployable space truss used for structural dynamics and active vibration-control research at the Langley Research Center. A comprehensive analysis of 306 frequency response functions (3 excitation forces and 102 displacement responses) was performed. Emphasis is placed on two topics of current research: (1) gaining an improved understanding of ERA performance characteristics (theory vs. practice); and (2) developing reliable techniques to improve identification results for complex experimental data. Because of nonlinearities and numerous local modes, modal identification of Mini-Mast proved to be surprisingly difficult. Methods were available, ERA, for obtaining detailed, high-confidence results.

    Blanken, C. L.; Pausder, H. J.; Ockier, C. J.

    1995-01-01

    An extensive investigation of the effects of pitch-roll coupling on helicopter handling qualities was performed by the U.S. Army and Deutsche Forschungsanstalt fur Luft- und Raumfahrt (DLR), using a NASA ground-based and a DLR in-flight simulator. Over 90 different coupling configurations were evaluated using a high gain roll-axis tracking task. The results show that although the current ADS-33C coupling criterion discriminates against those types of coupling typical of conventionally controlled helicopters, it is not always suited for the prediction of handling qualities of helicopters with modern control systems. Based on the observation that high frequency inputs during tracking are used to alleviate coupling, a frequency domain pitch-roll coupling criterion that uses the average coupling ratio between the bandwidth and neutral stability frequency is formulated. This criterion provides a more comprehensive coverage with respect to the different types of coupling, shows excellent consistency, and has the additional benefit that compliance testing data are obtained from the bandwidth/phase delay tests, so that no additional flight testing is needed.

    For the second German Spacelab Mission D-2 all activities related to operating, monitoring and controlling the experiments on board the Spacelab were conducted from the German Space Operations Control Center (GSOC) operated by the Deutsche Forschungsanstalt fur Luft- und Raumfahrt (DLR) in Oberpfaffenhofen, Germany. The operational requirements imposed new concepts on the transfer of data between Germany and the NASA centers and the processing of data at the GSOC itself. Highlights were the upgrade of the Spacelab Data Processing Facility (SLDPF) to real time data processing, the introduction of packet telemetry and the development of the high-rate data handling front end, data processing and display systems at GSOC. For the first time, a robot on board the Spacelab was to be controlled from the ground in a closed loop environment. A dedicated forward channel was implemented to transfer the robot manipulation commands originating from the robotics experiment ground station to the Spacelab via the Orbiter's text and graphics system interface. The capability to perform telescience from an external user center was implemented. All interfaces proved successful during the course of the D-2 mission and are described in detail in this paper.

    Due to magneto-elastic coupling, magnetic degrees of freedom are influenced by elastic deformation. We here demonstrate that the magneto-elastic interaction of a radio frequency (RF) surface acoustic wave (SAW) with a ferromagnetic thin film enables an all-elastic excitation and detection of ferromagnetic resonance (FMR). We have measured the SAW magneto-transmission at room temperature in Ni/ LiNb O3 hybrid devices as a function of SAW frequency, external magnetic field magnitude and orientation. Our data are consistently described by a modified Landau-Lifshitz-Gilbert approach, in which the magnetization precession is not driven by a conventional, external RF magnetic field, but rather by a purely virtual, internal tickle field stemming from RF magneto-elastic interactions. This causes a distinct magnetic field orientation dependence of elastically driven FMR, which we observe in both simulations and experiment.

    Hock, N.; Berresheim, H.; Borrmann, S.; Poeschl, U.; Roempp, A.; Schneider, J.

    2003-04-01

    The HAZE Experiment was conducted between 17.05.2002 and 31.05.2002, at the meteorological observatory of the Deutsche Wetterdienst (DWD) at Hohenpeissenberg (47^o48'N,11^o02'E, 985m). The objective was to make essential progress in understanding of the physical and chemical properties of the atmospheric aerosol, in particular relating to the Gas-To-Particle-Conversion and the interaction with meteorological processes. The measurements included online mass spectrometric analysis using the Aerosol Mass Spectrometer (AMS), filter samples with GC analyses of organic compounds, particle size distribution (Electrical Low Pressure Impactor (ELPI), SMPS, OPC), as well as the total particle concentration (CPC). Additionally, several gas-phase substances were measured (e.g. Benzene, Acetone). The measurements obtained with the AMS show a strong variability of the aerosol composition. The non-refractory aerosol composition was dominated by nitrate, sulphate, and organics, whereas ammonium was surprisingly low. High number concentration of up to 14000 particles/cm^3 were observed. These particles mostly had diameters between 200 nm and 400 nm and were mainly composed of ammonium sulphate and ammonium nitrate. Various meteorological conditions allowed to study their influence on the aerosol. For example, on rainy days the concentrations of ammonium sulphate particles decreased, whereas the concentrations of ammonium nitrate particles increased.

    Centrifugal Barrel polishing (CBP) is becoming a common R&D tool for SRF cavity preparation around the world. During the CBP process a cylindrically symmetric SRF cavity is filled with relatively cheap and environmentally friendly abrasive and sealed. The cavity is then spun around a cylindrically symmetric axis at high speeds uniformly conditioning the inner surface. This uniformity is especially relevant for SRF application because many times a single manufacturing defects limits cavity?s performance well below it?s theoretical limit. In addition CBP has created surfaces with roughness?s on the order of 10?s of nm which create a unique surface for wet chemistry or thin film deposition. CBP is now being utilized at Jefferson Laboratory, Fermi Laboratory and Cornell University in the US, Deutsches Elektronen-Synchrotron in Germany, Laboratori Nazionali di Legnaro in Italy, and Raja Ramanna Centre for Advanced Technology in India. In this talk we will present current CBP research from each lab including equipment, baseline recipes, cavity removal rates and subsequent cryogenic cavity tests on niobium as well as copper cavities where available.

  9. The National Socialist Sisterhood: an instrument of National Socialist health policy.

    When Adolf Hitler (1889-1945) came to power in 1933, the new Nazi government focused the German health system on their priorities such as the creation of a racially homogeneous society and the preparation of war. One of the measures to bring nursing under their control was the foundation of a new sisterhood. In 1934, Erich Hilgenfeldt (1897-1945), the ambitious head of the National Socialist People's Welfare Association (Nationalsozialistische Volkswohlfahrt), founded the National Socialist (NS) Sisterhood (Nationalsozialistische Schwesternschaft) to create an elite group that would work for the goals of the National Socialist German Workers' Party (Nationalsozialistische Deutsche Arbeiterpartei, NSDAP). Hilgenfeldt proclaimed community nursing as a priority for NS Sisterhood nurses. Catholic and Protestant sisters, who were traditionally dedicated to community nursing, were to be gradually replaced. However, other competing priorities, such as hospital service for the training of junior nurses and work in conquered regions, as well as the lack of NS nursing personnel, hampered the expansion of community nursing. The paper also addresses areas for future research: everyday activities of NS nurses, the service of NS Sisterhood nurses for NSDAP organisations such as the elite racist paramilitary force SS (Schutzstaffel, Protective Squadron), and involvement in their crimes have hardly been investigated as yet.

    Impulsive or 3He-rich solar energetic particle (SEP) events have been typically associated with jets or small EUV brightenings. We identify 30 impulsive SEP events from ACE at L1 during the solar minimum period 2007-2010 and examine their solar sources with high resolution STEREO-A EUV images. At beginning of 2007, STEREO-A was near the Earth while at the end of the investigated period, when there were more events, STEREO-A was leading the Earth by 90°. Thus STEREO-A provided a better (more direct) view on 3He-rich flares generally located on the western Sun's hemisphere. Surprisingly, we find that about half of the events are associated with large-scale EUV coronal waves. This finding provides new insights on acceleration and transport of 3He-rich SEPs in solar corona. It is believed that elemental and isotopic fractionation in impulsive SEP events is caused by more localized processes operating in the flare sites. The EUV waves have been reported in gradual SEP events in association with fast coronal mass ejections. To examine their role on 3He-rich SEPs production the energy spectra and relative abundances are discussed. R. Bucik is supported by the Deutsche Forschungsgemeinschaft under grant BU 3115/2-1.

    The spectroscopy of a single Rydberg atom within a Bose-Einstein condensate is studied, and as a result a line shape dependence on the principal Rydberg quantum number n is observed, apart from the expected density shift due to the large number of neutrals inside the Rydberg orbit. The observed line broadening depends on the Rydberg electron-neutral interaction, in particular, it manifests the influence of the e-Rb(5S) p-wave scattering shape resonance, which dramatically affects the potential energy landscape for the neutrals embedded within the Rydberg orbit. The observed spectroscopic line shapes are reproduced with an overall good agreement by means of a microscopic model, in which the atoms overlapped with the Rydberg orbit are treated as zero-velocity point-like particles, with binding energies associated with the ion-neutral distance.

  12. [Hans von Hattingberg between psychoanalysis and National Socialism].

    2011-01-01

    Hans von Hattingberg (1879-1944) worked as a neurologist and psychoanalyst in Munich and Berlin from about 1910 to 1944. He was a prolific writer, but met with increasing disapproval from Freud and his circle. An advocate of the union of different psychotherapeutic schools, he was initially a marginal figure in the professional field. With Hitler's rise to power his career prospered: He was offered the position of a lecturer for psychotherapy and became head of the research department at the "Göring Institute". He came to prominence with his writings on the "Neue deutsche Seelenheilkunde" despite the fact that this was never his preferred topic. The main themes of his publications were marriage, love and female emancipation. Those works contain only little of the standard Nazi ideology of the time. Not only was Hattingberg never a member of the NSDAP (the ruling party), but in some respects he could conceivably be considered a member of the resistance. The article outlines the most important stages of Hattingberg's life and focuses on the question of how he positioned himself after 1933, when it became vital for him to reconcile psychoanalysis and National Socialism.

    «Euthanasia» was the cynical euphemism used by the Nazis to refer to the systematic murder of hundreds of thousands of mentally sick and handicapped people between 1939 and 1945, at least 6,000 of whom were children. Based on the example of Günter Nevermann, this paper provides insight into the complex acts of registering, selecting, and targeting children labelled as "inferior" and "unworthy to live." This case clearly shows that Nazi doctors were not necessarily enmeshed in some tragic conflict. Rather, apparently without any qualms, they sacrificed the sick children who had been entrusted to their care, for the ideal of obtaining a "racially healthy corpus," a term used without being questioned. Most of the perpetrators were never brought to justice, and not a few of them later held managerial positions in child and adolescent psychiatry in the two German states. Many of them were members or even honorary members of the "Deutsche Gesellschaft für Kinder- und Jugendpsychiatrie, Psychosomatik und Psychotherapie e. V." in its present or previous form. We feel it is necessary to inform the public effectively about this state of affairs, to discover what really happened and to determine who was responsible.

    We have obtained multiple data sets from the SMA, PdBI, and IRAM 30m telescope of the Infrared Dark Cloud IRDC18223-3, the High-Mass Protostellar Object IRAS18151-1208, and the hot core source IRAS18507+0121 in order to search for clues regarding the role of rotation and disks in high mass star formation. These three objects allow us to compare the central-most regions surrounding the embedded continuum source at three different evolutionary stages of the formation process. Toward all three regions we see rotational or elongated structures perpendicular to the molecular outflows. Similarities and differences in the evolutionary sequence are discussed in the context of core and disk evolution. We have also carried out continuum and line radiative transfer modeling of the disk-like structures. Having a more complete picture of the evolutionary process that a massive star experiences will contribute significantly to the future of massive star formation research.

    The dynamics in the thin boundary layers of temperature and velocity is the key to a deeper understanding of turbulent transport of heat and momentum in thermal convection. The velocity gradient right at the heated plate of a Rayleigh-Bénard convection cell forms the two-dimensional skin friction field and is related to the formation of thermal plumes in the boundary layer right above the plate. Our analysis is based on a direct numerical simulation of Rayleigh-Bénard convection in a closed cylindrical cell of aspect ratio Γ = 1 and focused on the critical points of the skin friction field. We identify triplets of critical points, which are composed of two unstable nodes and a saddle between them, as the characteristic building block of the skin friction field. Isolated triplets as well as networks of triplets are detected. The majority of the ridges of line-like thermal plumes coincide with the unstable manifolds of the saddles. From a dynamical Lagrangian perspective, thermal plumes are formed together with an attractive hyperbolic Lagrangian Coherent Structure of the skin friction field. We discuss the differences from the skin friction field in turbulent channel flows from the perspective of the Poincaré-Hopf index theorem for two-dimensional vector field.

    An actinomycete strain was isolated from a soil sample collected from a secondary forest at Yongsheng of Yunnan province, China. The isolate, YIM 31634T, was identified by a polyphasic approach. The 16S rDNA sequence analysis showed that the strain YIM 31634T belongs to the genus Streptomyces, with closest similarity to Streptomyces olivochromogenes DSM 40451T (97.66% similarity). Sequence similarities between strain YIM 31634T and other Streptomyces species in the same subclade ranged from 97.59% (with Streptomyces resistomycificus DSM 40133T) to 97.22% (with Streptomyces mirabilis ATCC 27447T). Key phenotypic characteristics as well as chemotaxonomic features of the actinomyces were congruent with the description of the genus Streptomyces. On the basis of phenotypic and phylogenetic analyses, strain YIM31634T was recognized as a new species of the genus Streptomyces for which the name Streptomyces roseoalbus sp. nov. is proposed. The strain YIM 31634T has been deposited in the Chinese Center of Type Culture Collection as strain CCTCC M 203016T and in the Deutsche Sammlung von Mikroorganismen (DSM 41833T).

    Sensors for synthetic vision are needed to extend the mission profiles of helicopters. A special task for various applications is the autonomous position hold of a helicopter above a ground fixed or moving target. As a proof of concept for a general synthetic vision solution a restricted machine vision system, which is capable of locating and tracking a special target, was developed by the Institute of Flight Mechanics of Deutsche Forschungsanstalt fur Luft- und Raumfahrt e.V. (i.e., German Aerospace Research Establishment). This sensor, which is specialized to detect and track a square, was integrated in the fly-by-wire helicopter ATTHeS (i.e., Advanced Technology Testing Helicopter System). An existing model following controller for the forward flight condition was adapted for the hover and low speed requirements of the flight vehicle. The special target, a black square with a length of one meter, was mounted on top of a car. Flight tests demonstrated the automatic stabilization of the helicopter above the moving car by synthetic vision.

    We investigate intra-day foreign exchange (FX) time series using the inverse statistic analysis developed by Simonsen et al. (Eur. Phys. J. 27 (2002) 583) and Jensen et al. (Physica A 324 (2003) 338). Specifically, we study the time-averaged distributions of waiting times needed to obtain a certain increase (decrease) ρ in the price of an investment. The analysis is performed for the Deutsch Mark (DM) against the US for the full year of 1998, but similar results are obtained for the Japanese Yen against the US. With high statistical significance, the presence of “resonance peaks” in the waiting time distributions is established. Such peaks are a consequence of the trading habits of the market participants as they are not present in the corresponding tick (business) waiting time distributions. Furthermore, a new stylized fact, is observed for the (normalized) waiting time distribution in the form of a power law Pdf. This result is achieved by rescaling of the physical waiting time by the corresponding tick time thereby partially removing scale-dependent features of the market activity.

    This paper presents the successes and lessons learned during recent low NOx burner and SNCR projects on generating units at New England Power`s Salem Harbor Generating Station. The principals involved in the project were New England Power Company, New England Power Service Company, Stone and Webster Engineering Corp. and Deutsche-Babcock Riley Inc. One unit was retrofitted with 16 Riley CCV burners with an OFA system, the other with 12 low NOx burners only. In addition to the burners, a SNCR system was also installed on three units. Since each of the burner systems are interdependent (SNCR was treated separately during design phases and optimized along with the burner systems), close cooperation during the design stages was essential to ensuring a successful installation, startup and optimization. This paper will present the coordinated effort put forth by each company toward this goal with the hope of assisting others who may be planning a similar effort. A summary of the operating results will also be presented. The up front teamwork and advance planning that went into the design stages of the project resulted in a number of successful outcomes e.g. scanner reliability, properly operating oil supply system, compatibility of burners and burner front oil system with new Burner Management System (BMS), reliable first attempt burner ignition and more. Advance planning facilitated pre-outage work and factored into keeping schedules and budgets on track.

  20. Quantum Quench Dynamics in the Transverse Field Ising Model at Non-zero Temperatures

    Abeling, Nils; Kehrein, Stefan

    The recently discovered Dynamical Phase Transition denotes non-analytic behavior in the real time evolution of quantum systems in the thermodynamic limit and has been shown to occur in different systems at zero temperature [Heyl et al., Phys. Rev. Lett. 110, 135704 (2013)]. In this talk we present the extension of the analysis to non-zero temperature by studying a generalized form of the Loschmidt echo, the work distribution function, of a quantum quench in the transverse field Ising model. Although the quantitative behavior at non-zero temperatures still displays features derived from the zero temperature non-analyticities, it is shown that in this model dynamical phase transitions do not exist if T > 0 . This is a consequence of the system being initialized in a thermal state. Moreover, we elucidate how the Tasaki-Crooks-Jarzynski relation can be exploited as a symmetry relation for a global quench or to obtain the change of the equilibrium free energy density.

    This paper is an outline of a proposed initiative on intersectoral collaboration in health promotion--collaboration between health, tourist, cultural and entertainment sectors to provide a powerful mass educational experience about the human mind and body. There has been a recent rise in interest in using the technology of museums, science centres, exploratories and theme parks for the promotion of health. This revival is shown to have a historical tradition in the health education museum started in this century in Europe 75 years ago at the Deutsches Hygiene Museum and then spreading to the USA. The proposed Body, Mind, City Museum planned for Liverpool acts as a future model for a new type of health Museum; a mixture of science exploratorium and a Walt Disney-style them park. It is intended that "hand-on" exhibits using interactive video, computers, games and experiences will be used to test people's own capacities or to describe biological functions or processes. This will be combined with park rides and simulations with their inherent appeal of fun, movement and surprise, for example the ride through the blood vessels and the "walk-through brain". This type of venture has a number of special features and advantages; it is truly intersectoral, it may be self-financing, and it can provide a mass audience with a powerful individual experience.

    Doppler ultrasound scanning is the first line investigation for quantifying the internal carotid artery stenosis. Nevertheless, the lack of internationally accepted ultrasound criteria for describing the degree of stenosis has contributed to the different and confusing measurements ranges. The use of two different angiographic methods, the North American Symptomatic Carotid Endoarterectomy Study and the European Carotid Surgery Trial was probably the major initial source of confusion in deriving valid and reliable duplex ultrasound criteria worldwide. The consensus proposed in 2003 by the Society of Radiologists in Ultrasound has been a great attempt to create a conformity document, establishing grey scale and Doppler criteria in considering the different degrees of stenosis. According to this attempt, in 2010, the multi-parametric Deutsche Gesellschaft für Ultraschall in der Medizin ultrasound criteria have been proposed with a precise differentiation between main and additional criteria and depicted a different peak systolic velocity (PSV) threshold. In 2012, these criteria have been implemented, focusing on the multi-parametric approach, re-defining the PSV values and clearly introducing the concept of PSV average. Despite these attempts, a wide range of practice patterns still exists, with consistent disparities in patients' care. This paper collects these previous experiences and summarizes their strengths and weaknesses, to give a contribution in the carotid artery stenosis grading standardization using ultrasonic methods. Carotid ultrasound as the only diagnostic tool for the selection of patients for carotid surgery or stenting will be possible only with internationally accepted criteria. PMID:27298648

    Background The present study investigated the neural correlates of sign language processing of Deaf people who had learned German Sign Language (Deutsche Gebärdensprache, DGS) from their Deaf parents as their first language. Correct and incorrect signed sentences were presented sign by sign on a computer screen. At the end of each sentence the participants had to judge whether or not the sentence was an appropriate DGS sentence. Two types of violations were introduced: (1) semantically incorrect sentences containing a selectional restriction violation (implausible object); (2) morphosyntactically incorrect sentences containing a verb that was incorrectly inflected (i.e., incorrect direction of movement). Event-related brain potentials (ERPs) were recorded from 74 scalp electrodes. Results Semantic violations (implausible signs) elicited an N400 effect followed by a positivity. Sentences with a morphosyntactic violation (verb agreement violation) elicited a negativity followed by a broad centro-parietal positivity. Conclusions ERP correlates of semantic and morphosyntactic aspects of DGS clearly differed from each other and showed a number of similarities with those observed in other signed and oral languages. These data suggest a similar functional organization of signed and oral languages despite the visual-spacial modality of sign language. PMID:24884527

    Deutsche Flugsicherung GmbH, the German Air Navigation Service Provider, follows a systematic approach, called HERA, for investigating incidents. The HERA analysis shows a distinctive occurrence of incidents in German air traffic control in which the visual perception of information plays a key role. The reasons can be partially traced back to workstation design, where basic ergonomic rules and principles are not sufficiently followed by the designers in some cases. In cooperation with the Institute of Ergonomics in Darmstadt the DFS investigated possible approaches that may support designers to implement ergonomic systems. None of the currently available tools were found to be able to meet the identified user requirements holistically. Therefore it was suggested to develop an enhanced software tool called Design Process Guide. The name Design Process Guide indicates that this tool exceeds the classic functions of currently available Knowledge Management Systems. It offers "design element" based access, shows processual and content related topics, and shows the implications of certain design decisions. Furthermore, it serves as documentation, detailing why a designer made to a decision under a particular set of conditions.

    Ernst Rüdin (1874–1952) was one of the founders of psychiatric genetics. From 1931 until 1945, he was Director of the German Institute for Psychiatric Research (Deutsche Forschungsanstalt für Psychiatrie, DFA) and from 1935 until 1945 President of the German Association of Neurologists and Psychiatrists. The historical knowledge on Rüdin is reconsidered, using new sources, and with a focus on Rüdin’s involvement in the Nazi program of patient killings („euthanasia"). It is documented that (1) it is a misconception to interpret psychiatric genetics as „instrumentalised" by the Nazi regime; (2) Rüdin belonged to the group of psychiatric perpetrators who worked to give the Nazi selection policies scientific authority; (3) Rüdin knew early on about the patient killings and refused to support others in their efforts to stop them; and (4) the research in the context of the patient killings carried out by Julius Deussen, a member of Rüdin’s team at the DFA, was initiated and actively supported by Rüdin, and co-financed by the DFA.

  6. Spontaneous alignment in charged-particle systems: Fixed-length vs micellar situations

    1986-07-01

    We use a recently developed version of the soft-mean-spherical approximation (SMSA) to treat spontaneous alignment in suspensions of ionic, rod-like particles. In particular our theory derives from the charge-smearing idea of Onsager in which a lower bound is established for the free energy of the interacting system. First we treat the usual case of fixed-particle lengths and establish the regimes in which the charged lines behave like hard spherocylinders (i.e., the ``smearing'' length plays the role of a hard-core diameter). In general, the nematic phase is superceded by the solid whenever the rod length is too small or too large. Then we consider explicitly the micellar situation in which the particle lengths are determined by the thermodynamics (and vice versa). Here we find the possibility of a reentrant isotropic phase. At low temperatures the nematic becomes unstable because the alignment-induced growth leads to too large a charging (``self'') energy for the micelles. We also predict an ideal solution-like behavior for the growth of micelles in sufficiently concentrated isotropic phases. Finally we comment on the differences between our charge-smearing description of spontaneous alignment in ionic systems and a collective-coordinate approach due to Deutsch and Goldenfeld.

    In Germany dedicated neurological-neurosurgical critical care (NCC) is the fastest growing specialty and one of the five big disciplines integrated within the German critical care society (Deutsche Interdisziplinäre Vereinigung für Intensiv- und Notfallmedizin; DIVI). High-quality investigations based on resilient evidence have underlined the need for technical advances, timely optimization of therapeutic procedures, and multidisciplinary team-work to treat those critically ill patients. This evolution has repeatedly raised questions, whether NCC-units should be run independently or better be incorporated within multidisciplinary critical care units, whether treatment variations exist that impact clinical outcome, and whether nowadays NCC-units can operate cost-efficiently? Stroke is the most frequent disease entity treated on NCC-units, one of the most common causes of death in Germany leading to a great socio-economic burden due to long-term disabled patients. The main aim of NCC employs surveillance of structural and functional integrity of the central nervous system as well as the avoidance of secondary brain damage. However, clinical evaluation of these severely injured commonly sedated and mechanically ventilated patients is challenging and highlights the importance of neuromonitoring to detect secondary damaging mechanisms. This multimodal strategy not only requires medical expertise but also enforces the need for specialized teams consisting of qualified nurses, technical assistants and medical therapists. The present article reviews most recent data and tries to answer the aforementioned questions. PMID:27206707

    The planetary boundary layer (PBL) is the chemically most active and complex part of the atmosphere where freshly emitted reactive trace gases, tropospheric radicals, atmospheric oxidation products and aerosols exhibit a large variability and spatial gradients. In order to investigate the chemical degradation of trace gases and the formation of secondary pollutants in the PBL, a commercial Zeppelin NT was modified to be used as an airborne measurement platform for chemical and physical observations with high spatial resolution. The Zeppelin NT was developed by Zeppelin Luftschifftechnik (ZLT) and is operated by Deutsche Zeppelin Reederei (DZR) in Friedrichshafen, Germany. The modification was performed in cooperation between Forschungszentrum Jülich and ZLT. The airship has a length of 75 m, can lift about 1 ton of scientific payload and can be manoeuvered with high precision by propeller engines. The modified Zeppelin can carry measurement instruments mounted on a platform on top of the Zeppelin, or inside the gondola beneath the airship. Three different instrument packages were developed to investigate a. gas-phase oxidation processes involving free radicals (OH, HO2) b. formation of secondary organic aerosols (SOA) c. new particle formation (nucleation) The presentation will describe the modified airship and provide an overview of its technical performance. Examples of its application during the recent PEGASOS flight campaigns in Europe will be given.

  9. Origin of superconductivity in KFe2As2 under positive and negative pressures and relation to other Fe-based families

    NASA Astrophysics Data System (ADS)

    Valenti, Roser

    KFe2As2 shows an intricate behavior as a function of pressure. At ambient pressure the system is superconductor with a low critical temperature Tc=3.4 K and follows a V-shaped pressure dependence of Tc for moderate pressures with a local minimum at a pressure of 1.5 GPa. Under high pressures Pc=15 GPa, KFe2As2 exhibits a structural phase transition from a tetragonal to a collapsed tetragonal phase accompanied by a boost of the superconducting critical temperature up to 12 K. On the other hand, negative pressures realized through substitution of K by Cs or Rb decrease Tc down to 2.25K. In this talk we will discuss recent progress on the understanding of the microscopic origin of this pressure-dependent behavior by considering a combination of ab initio density functional theory with dynamical mean field theory and spin fluctuation theory calculations. We will argue that a Lifshitz transition associated with the structural collapse changes the pairing symmetry from d-wave (tetragonal) to s+/- (collapsed tetragonal) at high pressures while at ambient and negative pressures correlation effects appear to be detrimental for superconductivity. Further, we shall establish cross-links to the chalcogenide family, in particular FeSe under pressure. The Deutsche Forschungsgemeinschaft (DFG) is gratefully acknowledged for financial support.

    AGIPD—(Adaptive Gain Integrating Pixel Detector) is a hybrid pixel X-ray detector developed by a collaboration between Deutsches Elektronen-Synchrotron (DESY), Paul-Scherrer-Institut (PSI), University of Hamburg and the University of Bonn. The detector is designed to comply with the requirements of the European XFEL. The radiation tolerant Application Specific Integrated Circuit (ASIC) is designed with the following highlights: high dynamic range, spanning from single photon sensitivity up to 104 12.5keV photons, achieved by the use of the dynamic gain switching technique using 3 possible gains of the charge sensitive preamplifier. In order to store the image data, the ASIC incorporates 352 analog memory cells per pixel, allowing also to store 3 voltage levels corresponding to the selected gain. It is operated in random-access mode at 4.5MHz frame rate. The data acquisition is done during the 99.4ms between the bunch trains. The AGIPD has a pixel area of 200× 200 μ m2 and a 500μ m thick silicon sensor is used. The architecture principles were proven in different experiments and the ASIC characterization was done with a series of development prototypes. The mechanical concept was developed in the close contact with the XFEL beamline scientists and is now being manufactured. A first single module system was successfully tested at APS.

    The DLR MIRO is the second generation of versatile robot arms for surgical applications, developed at the Institute for Robotics and Mechatronics at Deutsche Zentrum für Luft- und Raumfahrt (DLR) in Oberpfaffenhofen, Germany. With its low weight of 10 kg and dimensions similar to those of the human arm, the MIRO robot can assist the surgeon directly at the operating table where space is scarce. The planned scope of applications of this robot arm ranges from guiding a laser unit for the precise separation of bone tissue in orthopedics to positioning holes for bone screws, robot assisted endoscope guidance and on to the multi-robot concept for endoscopic minimally invasive surgery. A stereo-endoscope delivers two full HD video streams that can even be augmented with information, e.g vectors indicating the forces that act on the surgical tool at any given moment. SeeFront's new autostereoscopic 3D display SF 2223, being a part of the MIRO assembly, will let the surgeon view the stereo video stream in excellent quality, in real time and without the need for any viewing aids. The presentation is meant to provide an insight into the principles at the basis of the SeeFront 3D technology and how they allow the creation of autostereoscopic display solutions ranging from smallest "stamp-sized" displays to 30" desktop versions, which all provide comfortable freedom of movement for the viewer along with excellent 3D image quality.

    Deutsche Flugsicherung GmbH, the German Air Navigation Service Provider, follows a systematic approach, called HERA, for investigating incidents. The HERA analysis shows a distinctive occurrence of incidents in German air traffic control in which the visual perception of information plays a key role. The reasons can be partially traced back to workstation design, where basic ergonomic rules and principles are not sufficiently followed by the designers in some cases. In cooperation with the Institute of Ergonomics in Darmstadt the DFS investigated possible approaches that may support designers to implement ergonomic systems. None of the currently available tools were found to be able to meet the identified user requirements holistically. Therefore it was suggested to develop an enhanced software tool called Design Process Guide. The name Design Process Guide indicates that this tool exceeds the classic functions of currently available Knowledge Management Systems. It offers "design element" based access, shows processual and content related topics, and shows the implications of certain design decisions. Furthermore, it serves as documentation, detailing why a designer made to a decision under a particular set of conditions. PMID:22317137

    Using the example of smoking, this article scrutinizes the notions of order, educational conduct and images of subjects in the health education of both German states between 1949 and the mid 70s. Drawing on archival sources, publications and educational media from both health ministries, the Deutsches Hygiene-Museum and the Bundeszentrale für gesundheitliche Aufklärung I reconstruct the organizational, conceptual and medial shift of health education from "citizenship" to a technology of communication and public relation, needing "scientification" in the 1960s. New epidemiological evidence fostered the belief in an efficacious prevention of manly coded and with smoking associated cardio-vascular diseases by forming healthy behavior. This went hand in hand with the increase of state responsibility for the health of its citizens and the import of new knowledge stemming from social research and new methodological expertise from advertising. At the same time the ideal of a comprehensible citizen shifted into a "socialist personality" that was to be shaped by a hierarchical and consistent education in the German Democratic Republic. In the Federal Republic of Germany the general principle of the self-determined citizen unfolded the antagonism of health education between individual emancipation and imposition. PMID:26536789

  14. The glissando illusion: A spatial illusory contour in hearing

    In the glissando illusion (originally demonstrated by Deutsch, 1995) a synthesized oboe tone of constant pitch is played together with a sine wave whose pitch repeatedly glides up and down. These are presented through two loudspeakers, placed to the listeners left and right, and are repeatedly switched between loudspeakers, such that when the oboe tone emanates from one, a segment of the sine wave emanates from the other. The oboe tone is perceived correctly as switching between loudspeakers; however the segments of the sine wave appear to be joined together seamlessly, such that a single, continuous tone is heard, which appears to emanate from a source that moves slowly around in space in accordance with its pitch motion. In the present experiment, righthanders (n=22) tended strongly to hear the glissando move between left and right, and also between low and high in space, as its pitch moved between low and high. It was therefore frequently heard as tracing an elliptical path aligned diagonally between a position low and to the left when its pitch was lowest, and high and to the right when its pitch was highest. Nonrighthanders (n=42) perceived the illusion in statistically different ways.

    Space weather can strongly affect the complex radiation field at aviation altitudes. The assessment of the corresponding radiation exposure of aircrew and passengers has been a challenging task as well as a legal obligation in the European Union for many years. The response of several radiation measuring instruments operated by different European research groups during joint measuring flights was investigated in the framework of the CONCORD (COmparisoN of COsmic Radiation Detectors) campaign in the radiation field at aviation altitudes. This cooperation offered the opportunity to measure under the same space weather conditions and contributed to an independent quality control among the participating groups. The CONCORD flight campaign was performed with the twin-jet research aircraft Dassault Falcon 20E operated by the flight facility Oberpfaffenhofen of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt, DLR). Dose rates were measured at four positions in the atmosphere in European airspace for about one hour at each position in order to obtain acceptable counting statistics. The analysis of the space weather situation during the measuring flights demonstrates that short-term solar activity did not affect the results which show a very good agreement between the readings of the instruments of the different institutes.

    The stable isotope analysis of the carbonate molecule bond in the phosphate-bearing mineral apatite provides a potential paleothermometer [1], but has also been used to address metabolism upon bio-apatite formation [2]. In the crystal lattice of apatite the carbonate group may substitute for both the hydroxyl ion and the phosphate in the crystal lattice, thereby potentially resulting in different isotope discrimination patterns. Within the EXCALIBOR project, stable isotope fractionation is investigated in biogenic apatites that were formed under known temperatures and in abiotic Ca phosphates precipitated under controlled laboratory conditions. Here, we report on the results from the synthesis experiments. Carbonate apatite was prepared at temperatures between 10° and 60°C by the precipitation from aqueous solutions or the transformation of CaCO3 precursors, taking care for a complete isotopic pre-equilibration in the aqueous carbonate system. Besides the analysis of the geochemical and stable isotope composition of the Ca phosphates and solutes, the solids were characterized by powder X-ray diffraction, FTIR and micro Raman spectroscopy. The latter techniques allow for an estimate of the position of the carbonate group (A/B type substitution) in the crystal lattice of apatite and will help to explore if this crystal chemical feature is associated with distinct stable isotope fractionation effects.

    From 1979 to 1982, 22 industrial companies (including 8 oil companies and 8 engine manufacturers) and 15 scientific institutes investigated the use of methanol fuels m15 and m100 in field tests within the scope of a 110-million-Deutsche-mark program financially supported by the federal ministry for research and technology of the Federal Republic of Germany. Thirty stations for m15 and 15 for m100 were set up across the country, and 989 vehicles were tested in day-to-day driving. One result may be stated definitely: the production and operation of m15 vehicles are technically possible. A prerequisite would be setting up a comprehensive m15 station network. The technical preconditions are known. M100 demonstrated a high degree of thermal efficiency in private automobile engines and favorable exhaust gas emission values. Optimization of the engines is currently in progress. The lubricating problems (wear in cylinders and deposits in the inlets systems) have not been satisfactorily solved yet. The m100 engines for commercial vehicles and buses were developed from diesel engines. They have attained the same high degree of thermal efficiency as diesel engines. The exhaust gas emission is free of soot and is favorable with respect to nitrogen oxides content. The wear problems with buses in city traffic have been overcome.

    In 2003, the program "The combined DAK therapy of obesity for children and adolescents", funded and conducted by the Deutsche Angestellten Krankenkasse (DAK) (A German Health Insurance Company), has started. The whole treatment lasts for 1 year including an initial inpatient therapy for 6 weeks followed by an outpatient treatment at home that adresses the overweight patients and their families. The therapy contents are developed according to the recommendations of the "Arbeitsgemeinschaft Adipositas im Kindes- und Jugendalter (AGA)". In a prospective cohort study a sample of 604 subjects was studied in order to examine the achievement of the treatment goals weight reduction, behaviour modification and improvement of quality of life. The development of weight was evaluated using BMI-SDS. 44,1% of children and adolescents had a successful weight reduction, they reduced their weight at least by 0,3 BMI-SDS. Furthermore, significant changes of health behaviour, physical fitness and quality of life were observed. However, during the outpatient treatment an impairment of some behaviour changes were observed. Nevertheless, the study has identified significant, positive effects in weight loss, behaviour modifications, changes in physical fitness and in the development of quality of life as a result of the therapy. It is demonstrated that a relapse in "old behaviour" followed by an increase of weight after the inpatient treatment can be avoided bythe subsequent outpatient therapy.

  19. Exploring the nonequilibrium dynamics of ultracold quantum gases by using numerical tools

    NASA Astrophysics Data System (ADS)

    Heidrich-Meisner, Fabian

    Numerical tools such as exact diagonalization or the density matrix renormalization group method have been vital for the study of the nonequilibrium dynamics of strongly correlated many-body systems. Moreover, they provided unique insight for the interpretation of quantum gas experiments, whenever a direct comparison with theory is possible. By considering the example of the experiment by Ronzheimer et al., in which both an interaction quench and the release of bosons from a trap into an empty optical lattice (sudden expansion) was realized, I discuss several nonequilibrium effects of strongly interacting quantum gases. These include the thermalization of a closed quantum system and its connection to the eigenstate thermalization hypothesis, nonequilibrium mass transport, dynamical fermionization, and transient phenomena such as quantum distillation or dynamical quasicondensation. I highlight the role of integrability in giving rise to ballistic transport in strongly interacting 1D systems and in determining the asymptotic state after a quantum quench. The talk concludes with a perspective on open questions concerning 2D systems and the numerical simulation of their nonequilibrium dynamics.

    Based on a measuring campaign which was carried out at Mallorca (39.6°N, 2.7°E) as cooperation between Agència Estatal de Meteorologia (AEMET) and Deutsches Zentrum für Luft- und Raumfahrt, engl. 'German Aerospace Center' (DLR) in 2011/2012 (September-January), 143 radiosondes (day and night) providing vertical temperature and wind profiles were released. Additionally, nocturnal mesopause temperature measurements with a temporal resolution of about 1 min were conducted by the infrared (IR) - Ground-based Infrared P-branch Spectrometer (GRIPS) during the campaign period. Strongly enhanced gravity wave activity in the lower stratosphere is observed which can be attributed to a hurricane-like storm (so-called Medicane) and to passing by cold fronts. Statistical features of gravity wave parameters including energy densitiy and momentum fluxes are calculated. Gravity wave momentum fluxes turned out being up to five times larger during severe weather. Moreover, gravity wave horizontal propagation characteristics are derived applying hodograph and Stokes parameter analysis. Preferred directions are of southeast and northwest due to prevailing wind directions at Mallorca.

    An acoustics test of a 40%-scale MBB BO-105 helicopter main rotor was conducted in the Deutsch-Niederlandischer Windkanal (DNW). The research, directed by NASA Langley Research Center, concentrated on the generation and radiation of broadband noise and impulsive blade-vortex interaction (BVI) noise over ranges of pertinent rotor operational envelopes. Both the broadband and BVI experimental phases are reviewed, along with highlights of major technical results. For the broadband portion, significant advancement is the demonstration of the accuracy of prediction methods being developed for broadband self noise, due to boundary layer turbulence. Another key result is the discovery of rotor blade-wake interaction (BWI) as an important contributor to mid frequency noise. Also the DNW data are used to determine for full scale helicopters the relative importance of the different discrete and broadband noise sources. For the BVI test portion, a comprehensive data base documents the BVI impulsive noise character and directionality as functions of rotor flight conditions. The directional mapping of BVI noise emitted from the advancing side as well as the retreating side of the rotor constitutes a major advancement in the understanding of this dominant discrete mechanism.

    Recent experimental advances have introduced an interplay in the trapping length scales of the lattice and the harmonic confinement. This fact motivates the investigation to prepare atomic gases at certain quantum states by utilizing a composite atomic trap consisting of a lattice potential that is embedded inside an overlying harmonic trap. In the present work, we examine how frequency modulations of the overlying harmonic trap stimulate the dynamics of an 1D few-boson gas. The gas is initially prepared at a highly confined state, and the subsequent dynamics induced by a quench of the harmonic trap frequency to a lower value is examined. It is shown that a non-interacting gas always diffuses to the outer sites. In contrast the response of the interacting system is more involved and is dominated by a resonance, which is induced by the bifurcation of the low-lying eigenstates. Our study reveals that the position of the resonance depends both on the atom number and the interaction coupling, manifesting its many body nature. The corresponding mean field treatment as well as the single-band approximation have been found to be inadequate for the description of the tunneling dynamics in the interacting case.

    Current studies at NASA Glenn on oxide thermodynamics are discussed. Previous studies on the vaporization of B2O3 in reducing atmospheres led to inconsistent studies when B was used as a reductant. It is shown that liquid B2O3 does not wet B and a clear phase separation was noted in the Knudsen cell. This problem was solved by using FeB and Fe2B to supply a different and constant activity of B. The thermodynamic data thus derived are compared to quantum chemical composite calculations. A major problem in high temperature mass spectrometry is the determination of accurate ionization cross sections, particularly for molecules. The method of Deutsch and Mark shows promise and some sample calculations are discussed. Finally current studies on the thermodynamics of rare earth silicates are discussed. Here the problems are obtaining a measurable signal from SiO2 vaporization and non-equilibrium vaporization. The use of a Ta reducing agent provides a stronger signal, which is related to silica activity. The Whitman-Motzfeld relation adapted to KEMS measurements is applied to obtain equilibrium pressures.

    Home mechanical ventilation is currently expanding in Chile, but its application along the country is hindered by financial and geographical reasons. In 2006 the San José Hospital in Santiago de Chile developed a non-invasive ventilation (NIV) center as a strategy to overcome the limitations of ventilator availability from public resources. Since then, this center provides intermittent diurnal sessions of NIV to patients with chronic hypercapnic respiratory failure. In 2013, a collaboratory work between the Chilean doctors, the German Interdisciplinary Society of Home Mechanical Ventilation (DIGAB = Deutsche Interdisziplinäre Gesellschaft für Außerklinische Beatmung) and the German non-invasive (NIV) home care provider "Heinen und Löwenstein" organized a donation of 100 second-hand ventilators (BiPAP Synchrony; Respironics, USA) including masks and tubing systems, which were provided by Heinen und Löwenstein. The ventilator devices arrived in Santiago in January 2014. Since then, the following initiatives have been launched: 1) the establishment of a domiciliary mechanical ventilation program independent of governmental founding, 2) NIV setting-titration, 3) renewal of ventilators at the hospital's intermittent NIV unit. Future goals are the establishment of a rehabilitation unit with concomitant NIV therapy and a clinical research program. Therefore, the German donation of ventilators and equipment has a reported impact on the development of NIV in Chile. PMID:25629262

    All mechanically ventilated patients must be weaned from the ventilator at some stage. According to an International Consensus Conference the criteria for "prolonged weaning" are fulfilled if patients fail at least 3 weaning attempts (i. e. spontaneous breathing trial, SBT) or require more than 7 days of weaning after the first SBT. This occurs in about 15 - 20 % of patients.Because of the growing number of patients requiring prolonged weaning a German guideline on prolonged weaning has been developed. It is an initiative of the German Respiratory Society (Deutsche Gesellschaft für Pneumologie und Beatmungsmedizin e. V., DGP) in cooperation with other societies (see acknowledgement) engaged in the field chaired by the Association of Scientific and Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF).This guideline deals with the definition, epidemiology, weaning categories, underlying pathophysiology, therapeutic strategies, the weaning unit, transition to out-of-hospital ventilation and therapeutic recommendations for end of life care. This short version summarises recommendations on prolonged weaning from the German guideline. PMID:26444135

This guidance is based on an interdisciplinary consensus. These recommendations are a prerequisite for the quality management in the treatment of patients with bone metastases from prostate cancer using (223)Ra. They are aimed at guiding nuclear medicine specialists in selecting candidates to receive therapy and to deliver the treatment in a safe and effective manner. The document contains background information and definitions. It covers the rationale, indications and contraindications for therapy with (223)Ra. Essential topics are the requirements for institutions performing the therapy, which patient data have to be available prior to performance of therapy, and how treatment has to be carried out technically and organisationally. Moreover, essential elements of follow-up and aftercare are specified. As a matter of principle, the treatment inclusive aftercare has to be realised in close cooperation with the involved medical disciplines.

    The Stratospheric Observatory For Infrared Astronomy (SOFIA) is an international cooperative development and operations program between the United States National Aeronautics and Space Administration (NASA) and the German Space Agency, DLR (Deutsches Zentrum fuer Luft-und Raumfahrt). SOFIA is a 2.5 meter, optical/infrared/sub-millimeter telescope mounted in a Boeing model 747SP-21 aircraft and will be used for many basic astronomical observations performed at stratospheric altitudes. It will accommodate installation of different focal plane instruments with in-flight accessibility provided by investigators selected from the international science community. The Facility operational lifetime is planned to be greater than 20 years. This presentation will present the results of developmental testing of SOFIA, including analysis, envelope expansion and the first operational mission. It will describe a brief history of open cavities in flight, how NASA designed and tested SOFIAs cavity, as well as flight test results. It will focus on how the test team achieved key milestones by systematically and efficiently reducing the number of test points to only those absolutely necessary to achieve mission requirements, thereby meeting all requirements and saving the potential loss of program funding. Finally, it will showcase examples of the observatory in action and the first operational mission of the observatory, illustrating the usefulness of the system to the international scientific community. Lessons learned on how to whittle a mountain of test points into a manageable sum will be presented at the conclusion.

    Because of their high temporal resolution and good preservation, speleothem records are often used as indicators for past climatic conditions. During the last years, substantial scientific progress has been made on the interpretation of these proxy records in terms of temperature and precipitation changes. Unfortunately, the link between climatic conditions within the cave (as depicted from the speleothems) to the climate outside the cave is not straightforward for many cave locations. In order to improve this connection, it is important to have accurate speleothems data as well as high-resolution large-scale climate data. In this study we focus on the latter problem. Within the framework of the DAPHNE ("Dated Speleothems Archives of the Paleoenvironment") Project we investigated available climate measurements (stations from the Deutsche Wetterdienst and from the Global Network of Isotopes in Precipitation) in the region surrounding the Bunker Cave, which is located close to Iserlohn in Germany. These measurements are compared, on a larger scale, to reanalysis data (ECMWF-ERA40) and simulation results from an atmospheric general circulation model with isotope diagnostics built into the models hydrological cycle (ECHAM). We used statistical downscaling to establish a connection between the large-scale information and the local climate surrounding the Bunker Cave. Understanding how the local present-day climate above the cave is influenced will largely improve our knowledge of palaeoclimate as derived from the speleothem records.

    The reconstruction of the evolutionary history of this professional association lays its focus on the developments which contributed to the society’s formal foundation during the time of the patient killings in Germany after 1939. Methodologically the study follows strategies of historical network analysis including the main actors of the foundation process. The foundation of this society can be seen as the result of the interaction of a) the Reichs-Health-Agency, its president Hans Reiter, and Fritz Rott as National Socialist health politicians, b) the scientific development geared to this policy of a young discipline that shared its knowledge base as well as its medical ‘object’ with established specialties like psychiatry and pediatrics, c) a postulated need for character studies, prognosis and selection, and d) personal as well as professional-political interests of the main protagonists Schroeder and Villinger. Once more it is obvious that medicine and politics were not only interwoven, but in certain areas in accordance with each other. Borders could rather be established between social regulatory “instances”. The foundation of the DGKH (Deutsche Gesellschaft für Kinderpsychiatrie und Heilpädagogik; German Society for Child Psychiatry and Therapeutic Education) is an example of a ‘radical regulatory reasoning’ according to Raphael, that by means of “institutional arrangements at medium level” (Raphael, 2001) was supposed to implement the ‘new National-Socialist order’.

    We describe the genomic organization and functional characterization of the mouse gene encoding vascular endothelial growth factor (VEGF), a polypeptide implicated in embryonic vascular development and postnatal angiogenesis. The coding region for mouse VEGF is interrupted by seven introns and encompasses approximately 14 kilobases. Organization of exons suggests that, similar to the human VEGF gene, alternative splicing generates the 120-, 164-, and 188-amino acid isoforms, but does not predict a fourth VEGF isoform corresponding to human VEGF206. Approximately 1. 2 kilobases of 5'-flanking region have been sequenced, and primer extension analysis identified a single major transcription initiation site, notably lacking TATA or CCAT consensus sequences. The 5'-flanking region is sufficient to promote a 7-fold induction of basal transcription. The genomic region encoding the 3'-untranslated region was determined by Northern and nuclease mapping analysis. Investigation of mRNA sequences responsible for the rapid turnover of VEGF mRNA (mRNA half-life, <1 h) (Shima, D. T. , Deutsch, U., and D'Amore, P. A. (1995) FEBS Lett. 370, 203-208) revealed that the 3'-untranslated region was sufficient to trigger the rapid turnover of a normally long-lived reporter mRNA in vitro. These data and reagents will allow the molecular and genetic analysis of mechanisms that control the developmental and pathological expression of VEGF.

    GET Fit was first conceived in January 2010 when the United Nations Secretary General's Advisory Group on Energy and Climate Change (AGECC) invited Deutsche Bank Climate Change Advisors (DBCCA) to present new concepts to drive renewable energy investment in developing regions. DBCCA responded with the Global Energy Transfer Feed-in Tariffs Program (GET FiT), a proposal to support both renewable energy scale up and energy access through the creation of new international public-private partnerships. The concept was inspired by the theory that feed-in tariffs could serve as an effective policy structure for both public and private investment and knowledge transfer from the developed world. The original GET FiT concept was designed with input from over 160 individuals from the renewable energy, financial and international development communities. The original GET FiT report was issued in April 2010. This report reflects continued engagement of stakeholders around the world. GET FiT plus is an effort to capture the key outcomes of the GET FiT consultation process and use them to catalyze ongoing dialogue and debate about the future of international support for renewable energy in developing regions. These outcomes have been translated into key research priorities. These priorities, as well as some short issue briefs are part of this report.

    Prof. Kohn (1867-1959) was the head of the Institute of Histology at the Medical Faculty of German University in Prague for 26 years. In 2007 we commemorated his 140th birthday, and 2009 we will remember the 50th anniversary of his death. He entered the history of medicine by discovery of nature and origin of parathyroid glands and by pioneer research into chromaffin cells and sympathetic paraganglia. Kohn's papers on the pituitary, interstitial cells of testes, and ovaries are also related to endocrinology. All his studies are based on descriptive and comparative histological and embryological observations. Kohn was twice the dean of German Medical Faculty, and a member or honorary member of many important scientific societies. He was repeatedly nominated for Nobel Prize for physiology and medicine. For his Jewish origin he was expelled from Deutsche Gesellschaft der Wissenschaften und Künste für die Tschechoslowakische Republik in 1939 and transported to Terezin ghetto in 1943. After the war he lived in Prague. On the occasion of his 90th birthday he was elected honorary president of Anatomische Gesellschaft and awarded by the Czechoslovak Order of Labour. Alfred Kohn died in 1959. He was one of the outstanding personalities that Prague gave to the world of science.

    Technological disasters and hazardous natural threats are often correlated or even caused by severe thunderstorms. In particular, when a disaster has happened and subsequent human actions of various kinds are activated, it may be helpful to become aware of severe thunderstorms in the area concerned. For example, airports become closed and squadrons working in the open air are called back when lightning threats are expected or do occur. Although thunderstorm recognition and short-term prediction is not considered as a one of the primary subjects in connection with technological dis-asters, it represents background information that should be available in any case, and with high reliability. The present contribution summarizes the status of storm detection and demonstrates the features of the largest lightning location network in Europe (LINET), developed by the Physics Department of the University of Munich, and operated by nowcast GmbH in Munich. Some of the outstanding features of LINET are briefly highlighted. Further-more, it is explained how nowcasting of storms is achieved with the use of only light-ning data, and in combination with radar and other meteorological data sources. Re-sults of co-operations with other research groups, mainly with DLR (Deutsche Luft- und Raumfahrt), and within the project RegioExAKT, funded by the German Government in order to improve nowcasting at airports, are detailed.

  15. The New APD Based Readout for the Crystal Barrel Calorimeter

    2015-02-01

    The CBELSA/TAPS experiment at ELSA measures double polarization observables in meson photoproduction off protons and neutrons. To be able to measure purely neutral reactions off polarized neutrons with high efficiency, the main calorimeter has to be integrated into the first level trigger. This requires to exchange the existing PIN photo diode by a new avalanche photo diode (APD) readout. The newly developed readout electronics will provide an energy resolution compatible to the previous set-up and a fast trigger signal down to 10 MeV energy deposit per crystal. After the successful final tests with a 3x3 CsI crystal matrix in Bonn at ELSA and in Mainz at MAMI all front-end electronics were produced in fall 2013. Automated test routines for the front-end electronics were developed and the characterization measurements of all APDs were successfully accomplished in Bonn. The project is supported by the Deutsche Forschungsgemeinschaft (SFB/TR16) and Schweizerischer Nationalfonds.

  16. The National Socialist Sisterhood: an instrument of National Socialist health policy.

    When Adolf Hitler (1889-1945) came to power in 1933, the new Nazi government focused the German health system on their priorities such as the creation of a racially homogeneous society and the preparation of war. One of the measures to bring nursing under their control was the foundation of a new sisterhood. In 1934, Erich Hilgenfeldt (1897-1945), the ambitious head of the National Socialist People's Welfare Association (Nationalsozialistische Volkswohlfahrt), founded the National Socialist (NS) Sisterhood (Nationalsozialistische Schwesternschaft) to create an elite group that would work for the goals of the National Socialist German Workers' Party (Nationalsozialistische Deutsche Arbeiterpartei, NSDAP). Hilgenfeldt proclaimed community nursing as a priority for NS Sisterhood nurses. Catholic and Protestant sisters, who were traditionally dedicated to community nursing, were to be gradually replaced. However, other competing priorities, such as hospital service for the training of junior nurses and work in conquered regions, as well as the lack of NS nursing personnel, hampered the expansion of community nursing. The paper also addresses areas for future research: everyday activities of NS nurses, the service of NS Sisterhood nurses for NSDAP organisations such as the elite racist paramilitary force SS (Schutzstaffel, Protective Squadron), and involvement in their crimes have hardly been investigated as yet.

    Whereas visual demonstrations of multistability are ubiquitous, there are few auditory examples. The purpose of the current study was to determine whether simultaneously presented melodies, such as underlie the scale illusion [Deutsch (1975). J. Acoust. Soc. Am. 57(5), 1156-1160], can elicit multiple mutually exclusive percepts, and whether reported perceptions are mediated by musical expertise. Participants listened to target melodies and reported whether the target was embedded in subsequent test melodies. Target sequences were created such that they would only be heard if the listener interpreted the test melody according to various perceptual cues. Critically, and in contrast with previous examinations of the scale illusion, an objective measure of target detection was obtained by including target-absent test melodies. As a result, listeners could reliably identify target sequences from different perceptual organizations when presented with the same test melody on different trials. This result demonstrates an ability to alternate between mutually exclusive percepts of an unchanged stimulus. However, only perceptual organizations consistent with frequency and spatial cues were available and musical expertise did mediate target detection, limiting the organizations available to non-musicians. The current study provides the first known demonstration of auditory multistability using simultaneously presented melodies and provides a unique experimental method for measuring auditory perceptual competition.

    In this work, a time-of-flight (TOF) mass spectrometer has been used to investigate the distribution of intermediate species and formation process of carbon clusters. The graphite sample was ablated by Nd:YAG laser (532 nm and 1064 nm). The results indicate that the maximum size distribution shifted towards small cluster ions as the laser fluence increased, which happened because of the fragmentation of larger clusters in the hot plume. The temporal evolution of ions was measured by varying the delay time of the ion extraction pulse with respect to the laser irradiation, which was used to provide distribution information of the species in the ablated plasma plume. When the laser fluence decreased, the yield of all of the clusters obviously dropped. supported by the National Magnetic Confinement Fusion Science Program of China (No. 2013GB109005) and National Natural Science Foundation of China (No. 11175035), Chinesisch-Deutsches Forschungs Project (GZ768), the Fundamental Research Funds for the Central Universities of China (Nos.

    This four-frame mosaic shows the ancient impact structure Asgard on Jupiter's moon Callisto. This image is centered at 30 degrees north, 142 degrees west. The Asgard structure is approximately 1700 km across (1,056 mi) and consists of a bright central zone surrounded by discontinuous rings. The rings are tectonic features with scarps near the central zone and troughs at the outer margin. Several large impacts have smashed into Callisto after the formation of Asgard. The very young, bright-rayed crater Burr is located on the northern part of Asgard. This mosaic has been projected to show a uniform scale between the four mosaiced images. The image was processed by Deutsche Forschungsanstalt fuer Luftund Raumfahrt e.V., Berlin, Germany.

    This image was taken on November 4, 1996, at a distance of 111,891 kilometers (69,070 miles) by the solid state imaging television camera onboard the Galileo spacecraft during its third orbit around Jupiter.

    Quantum computers can solve certain problems more efficiently than any possible conventional computer. Small quantum algorithms have been demonstrated on multiple quantum computing platforms, many specifically tailored in hardware to implement a particular algorithm or execute a limited number of computational paths. Here we demonstrate a five-qubit trapped-ion quantum computer that can be programmed in software to implement arbitrary quantum algorithms by executing any sequence of universal quantum logic gates. We compile algorithms into a fully connected set of gate operations that are native to the hardware and have a mean fidelity of 98 per cent. Reconfiguring these gate sequences provides the flexibility to implement a variety of algorithms without altering the hardware. As examples, we implement the Deutsch-Jozsa and Bernstein-Vazirani algorithms with average success rates of 95 and 90 per cent, respectively. We also perform a coherent quantum Fourier transform on five trapped-ion qubits for phase estimation and period finding with average fidelities of 62 and 84 per cent, respectively. This small quantum computer can be scaled to larger numbers of qubits within a single register, and can be further expanded by connecting several such modules through ion shuttling or photonic quantum channels.

  1. Undecidability Theorem and Quantum Randomness

    NASA Astrophysics Data System (ADS)

    Berezin, Alexander A.

    2005-04-01

    As scientific folklore has it, Kurt Godel was once annoyed by question whether he sees any link between his Undecidability Theorem (UT) and Uncertainty Relationship. His reaction, however, may indicate that he probably felt that such a hidden link could indeed exist but he was unable clearly formulate it. Informational version of UT (G.J.Chaitin) states impossibility to rule out algorithmic compressibility of arbitrary digital string. Thus, (mathematical) randomness can only be disproven, not proven. Going from mathematical to physical (mainly quantum) randomness, we encounter seemingly random acts of radioactive decays of isotopes (such as C14), emission of excited atoms, tunneling effects, etc. However, our notion of quantum randomness (QR) may likely hit similarly formidable wall of physical version of UT leading to seemingly bizarre ideas such as Everett many world model (D.Deutsch) or backward causation (J.A.Wheeler). Resolution may potentially lie in admitting some form of Aristotelean final causation (AFC) as an ultimate foundational principle (G.W.Leibniz) connecting purely mathematical (Platonic) grounding aspects with it physically observable consequences, such as plethora of QR effects. Thus, what we interpret as QR may eventually be manifestation of AFC in which UT serves as delivery vehicle. Another example of UT/QR/AFC connection is question of identity (indistinguishability) of elementary particles (are all electrons exactly the same or just approximately so to a very high degree?).

  2. Rayleigh- and Prandtl-number dependence of the large-scale flow-structure in weakly-rotating turbulent thermal convection

    2015-11-01

    Turbulent thermal convection under rotation shows a remarkable variety of different flow states. The Nusselt number (Nu) at slow rotation rates (expressed as the dimensionless inverse Rossby number 1/Ro), for example, is not a monotonic function of 1/Ro. Different 1/Ro-ranges can be observed with different slopes ∂Nu / ∂ (1 / Ro) . Some of these ranges are connected by sharp transitions where ∂Nu / ∂ (1 / Ro) changes discontinuously. We investigate different regimes in cylindrical samples of aspect ratio Γ = 1 by measuring temperatures at the sidewall of the sample for various Prandtl numbers in the range 3 < Pr < 35 and Rayleigh numbers in the range of 108 < Ra < 4 ×1011 . From these measurements we deduce changes of the flow structure. We learn about the stability and dynamics of the large-scale circulation (LSC), as well as about its breakdown and the onset of vortex formation close to the top and bottom plate. We shall examine correlations between these measurements and changes in the heat transport. This work was supported by NSF grant DRM11-58514.

    2016-01-01

    The reconstruction of the evolutionary history of this professional association lays its focus on the developments which contributed to the society’s formal foundation during the time of the patient killings in Germany after 1939. Methodologically the study follows strategies of historical network analysis including the main actors of the foundation process. The foundation of this society can be seen as the result of the interaction of a) the Reichs-Health-Agency, its president Hans Reiter, and Fritz Rott as National Socialist health politicians, b) the scientific development geared to this policy of a young discipline that shared its knowledge base as well as its medical ‘object’ with established specialties like psychiatry and pediatrics, c) a postulated need for character studies, prognosis and selection, and d) personal as well as professional-political interests of the main protagonists Schroeder and Villinger. Once more it is obvious that medicine and politics were not only interwoven, but in certain areas in accordance with each other. Borders could rather be established between social regulatory “instances”. The foundation of the DGKH (Deutsche Gesellschaft für Kinderpsychiatrie und Heilpädagogik; German Society for Child Psychiatry and Therapeutic Education) is an example of a ‘radical regulatory reasoning’ according to Raphael, that by means of “institutional arrangements at medium level” (Raphael, 2001) was supposed to implement the ‘new National-Socialist order’.

    The need for effective leadership is a compelling priority for those who would choose to govern in public, private, and nonprofit organizations, and applies as much to the healthcare profession as it does to other sectors of the economy (Moody, Horton-Deutsch, & Pesut, 2007). Transformative Leadership, an approach to leadership and governance that incorporates the best characteristics of six other highly respected leadership models, is an integrative theory of ethical stewardship that can help healthcare professionals to more effectively achieve organizational efficiencies, build stakeholder commitment and trust, and create valuable synergies to transform and enrich today's healthcare systems (cf. Caldwell, LeJeune, & Dixon, 2007). The purpose of this article is to introduce the concept of Transformative Leadership and to explain how this model applies within a healthcare context. We define Transformative Leadership and identify its relationship to Transformational, Charismatic, Level 5, Principle-Centered, Servant, and Covenantal Leadership--providing examples of each of these elements of Transformative Leadership within a healthcare leadership context. We conclude by identifying contributions of this article to the healthcare leadership literature.

    A nonintrusive Moire interferometry system has been designed to acquire the instantaneous deformation of models during wind tunnel testing. The resulting interferograms are evaluated without manual intervention using a technique based on the Fourier Transform. The deformation of a large- scale model wing (generic model of a transport aircraft with a full span of 3.40 m) has been measured in the 8 m X 6 m test section of the subsonic Deutsch-Niederlandischer-Windkanal (DNW). At 400 individual locations along the span, the bending and twist deformations of the wing have been measured with an average accuracy of +/- 0.1 mm and +/- 0.03 degree(s), respectively. In a second experiment, the bending angle of a flap of a hypersonic vehicle was measured in order to determine the hinge moment due to aerodynamic loads. The experiment was carried out in the transonic wind tunnel Gottingen (TWG). To obtain data for comparison, the hinges were equipped with strain gauges. The results of both techniques show a maximum deviation of 0.02 degree(s).

    In Bavaria the curriculum of the upper grade of high school includes a so called project seminar, running over one and a half year. The aims of the seminar are to let the pupils learn to work on a specific topic, to organize themselves in a team, to improve their soft skills and become familiar with the working life. The topic of the project seminar, jointly organized by the Bertold-Brecht-Gymnasium in Munich and the Deutsche Geodätische Forschungsinstitut (DGFI) was on the "Global sea level rise". A team of 13 pupils computed the mean sea level rise by using on the one hand altimetry data of TOPEX, Jason-1 and Jason2 and on the other hand data of globally distributed tide gauges, corrected for vertical crustal movements derived from GPS products. The results of the two independent approaches were compared with each other and discussed considering also statements and discussions found in press, TV, and the web. Finally, a presentation was prepared and presented at school.

    We give a brief survey on our latest activities in atom interferometry. This included the first quantum test of the principle of equivalence with two different species, namely potassium and rubidium. We have also shown that interferometers equipped with atom-chip based sources allow to realise compact quantum gravimeters for ground based measurements. These devices allow to achieve a high flux of ultra-cold atoms, extremely low expansion rates of these wave packets and make it possible to realise new interferometers. Last but not least, in 2014, we currently work on testing these devices in the catapult and on a sounding rocket mission to extend atom interferometry to unprecedented time scales.

    New high precision measurements of the difference in neutron total cross sections of deuterium and hydrogen (d-h) were performed for neutron energies between 10 and 600 MeV. The results are compared to state-of-the-art Faddeev calculations of the n+d total cross section between 10 and 300 MeV, which systematically underpredict the experiment above 100 MeV. This result is not very sensitive to the type of modern NN interaction employed. Further, the convergence of the Faddeev multiple scattering series is demonstrated. We therefore conclude that the Faddeev description is inadequate above 100 MeV projectile energy. We also consider the first and second order terms in the multiple scattering series in the high energy limit to study shadowing effects.

    We have recently measured neutron total cross sections for hydrogen and the total cross section difference for deuterium-hydrogen (d-h) over a wide energy range (approximately 10-600 MeV projectile energy). These measurements were made by an attenuation technique at the LANSCE/WNR facility using samples of D_2O, H_2O, C_8H_18, and CH2 with a technique similar to that applied in Ref. [1]. The results for d-h are in significant disagreement with previous measurements of this quantity (up to 9% near 80 MeV). The results have been used to test the Faddeev description of the n+d total cross section between 10 and 300 MeV as reported in the following abstract. [1mm] [1] R.W. Finlay et al., Phys. Rev.

    We seek to extract the kinematic fingerprints of baryon resonances by making use of a high-quality beam of linearly polarized photons at the BGO-OD experiment at ELSA (Bonn, German). We constructed a unique device for precisely determining the degree of polarization in the coherent bremsstrahlung peak. Deflection of post-bremsstrahlung electrons in the magnetic field of the photon tagger provides precise information on the energy and polarization of the bremsstrahlung photons. And thereby will constrain the overall kinematics of the final-state particles in all decay channels of the photoproduced baryon resonances. We designed, prototyped, built, calibrated, and have been operating a three-layered, multi-stranded, scintillating-fiber detector for ensuring the quality of the linearly polarization of the photon beam. The overlapping 2.00-mm scintillating fibers form an array giving ARGUS over 500 channels. The very befitting name harkens to the mythological all-seeing creature Argus Panoptes, the multi-eyed giant.

    Since 2004 applications for research funding in ophthalmology have been evaluated together with those from neurosurgery, neuropathology, psychiatry, psychotherapy, psychosomatics, otolaryngology and neurology by a joint review board of the German Research Council (DFG). Facing a decreasing number of applications--in contrast to the need and importance of widespread ocular diseases--the working group "young academics" of the Deutsche Ophthalmologische Gesellschaft (DOG) assessed the perception of funding programmes and grants available. Young ophthalmologists think that they have poor prospects to receive funding by a DFG proposal. In comparison, specialist funding quotas show a stable development within the neurosciences over the last years. The sum of requested funding has a strong correlation with the total amount actually paid. By clarifying the number of funded proposals, the better transparency and communication for the existing programmes should improve the cooperativeness, the funding rate and number of applications in future. This inventory explicitly includes a motivational guidance for young researchers to take the initiative to do more proposals.

    Analyzing the surface composition of Venus from remote-sensing measurements is a challenging task. Recently we have reported on brightness variations in the near infrared wavelength range observed with VIRTIS on VenusExpress. Our implication is that these brightness variations might be correlated to emissivity variations of the surface material. The next step to verify this hypothesis is to obtain data in the relevant spectral range at temperatures typical for the surface of Venus. We are currently developing a Planetary Emissivity Laboratory (PEL) at Deutsches Zentrum für Luft- und Rahmfahrt (DLR) in Berlin. The PEL allows measuring the emissivity of planetary analog materials grain sizes fractions from less than 25 microns all the way to bulk samples and at temperatures of more than 400°C, typically for the surface of Venus. The PEL development follows a multi-step approach. We are currently installing a new calibration target that will allow obtaining emissivity data on the full range from 1 to 50 microns with a usable signal-to-noise ratio. Here we will present first data in the range from 1 to 1.4 microns which covers the atmospheric windows used for the surface observations from VIRTIS on VenusExpress. We will focus especially on which measurements are necessary to verify our earlier hypotheses of compositional variations on the surface of Venus.

After a period of five years the studies have been completed in summer '92 and the following results were achieved: 1) Homoeopathic drugs (considering the similarity) are suitable to reduce the morbidity rate of newly housed fattening pigs effectively by metaphylactic treatments. 2) The efficiency of the combination Lachesis, Pyrogenium, Echinacea and Chlorophyll (Laseptal) for curing respiratory infections is comparable to the one of Oxytetrazycline and the combination of Sulfadimidin and Trimethoprim. 3) A significant therapeutical effect was achieved by homoeopathic treatment in dairy herds so that the use of allopathic drugs can be reduced considerably. 4) Homoeopathic drugs, including nosodes, show hardly or do not at all show a positive influence on chronic mastitis in cows, especially increased cell counts combined with latent infections of pathogenic micro-organisms. 5) Drying off cows with Phytolacca D1 only does not reduce the milk quantity or prevent the occurrence of mastitis during the non-lactating period. 6) The combination Sabina, Pulsatilla, Lachesis and Pyrogenium (proposed to improve the puerperal period after placental retention) compared with standard allopathic treatment is not suitable to improve the puerperal period or fertility after retention of placenta.(ABSTRACT TRUNCATED AT 250 WORDS)

    The report describes seven SMA-cases in descendents of crossbreeds of American Brown Swiss x Deutsches Braunvieh. Symptoms and course: After initially normal development of the calves for one to six weeks the disease set in suddenly followed by a rapid lethal course of one to one and a half weeks duration due to asphyxia and/or secondary diseases. Only one case was reported having been sick since birth (?). Characteristic signs were rapidly progressing muscular atrophy, paresis and paralysis of the limbs, the trunk and the diaphragm, usually accompanied by progressive dyspnoea. Signs of congenital neuromyodysplasia (arthrogryposis) of different degree were present in four of the seven calves. Six calves had contracted a secondary pneumonia. Blood gas analysis (6/7) revealed a compensated (1x) or decompensated (4x) respiratory acidosis. Neurohistological findings: Degeneration and loss of motor neurons in the ventral horns of the spinal cord and neurogenic muscular atrophy. Immunohistochemistry revealed a pronounced accumulation of type 200 kD-neurofilaments in perikarya and dendrites of ventral horn motoneurons indicating disturbed mechanisms of the axonal transport. The disease seems to be inherited as a recessive trait.

    Acoustic data taken in the anechoic Deutsch-Niederlaendischer Windkanal (DNW) have documented the blade vortex interaction (BVI) impulsive noise radiated from a 1/7-scale model main rotor of the AH-1 series helicopter. Averaged model scale data were compared with averaged full scale, inflight acoustic data under similar nondimensional test conditions. At low advance ratios (mu = 0.164 to 0.194), the data scale remarkable well in level and waveform shape, and also duplicate the directivity pattern of BVI impulsive noise. At moderate advance ratios (mu = 0.224 to 0.270), the scaling deteriorates, suggesting that the model scale rotor is not adequately simulating the full scale BVI noise; presently, no proved explanation of this discrepancy exists. Carefully performed parametric variations over a complete matrix of testing conditions have shown that all of the four governing nondimensional parameters - tip Mach number at hover, advance ratio, local inflow ratio, and thrust coefficient - are highly sensitive to BVI noise radiation.

We also perform a coherent quantum Fourier transform on five trapped-ion qubits for phase estimation and period finding with average fidelities of 62 and 84 per cent, respectively. This small quantum computer can be scaled to larger numbers of qubits within a single register, and can be further expanded by connecting several such modules through ion shuttling or photonic quantum channels.

    The central question of this study is why workers in the employable age group apply for disability pension although from a medical point of view their vocational ability is maintained. The aim is to identify factors in the system and of the applicant which may serve as subjective prognostic indicators for maintaining employment and for determining influences which may be of prognostic value for a pension application. Concomitantly, it is aimed to obtain guidelines for practical rehabilitation and to generate impulses for further research in this field. Within a qualitative research project 16 problem-focused interviews with patients insured by "Deutsche Rentenversicherung Nord" and treated in a cardiac rehabilitation centre in Mecklenburg-Vorpommern were undertaken. Patients with either a positive or a negative subjective prognosis concerning employment were interviewed. In addition, the interviews were followed by a questionnaire one year later. The results show differences and similarities in the motivation of patients applying for disability pension. This can be traced back to psychosocial variables, sociodemographic characteristics, moderating factors and the effects of socialisation. Physical impairment was of secondary importance to the patients' motivation to apply for disability pension. The results of the follow-up questionnaire show that an existing job significantly improves the subjective prognosis for maintaining gainful employment. The application for disability pension offers the affected individual a possibility to ensure a basic existence in the case of illness and unemployment. The identified factors may be influenced by modifying the interventions and improving medical counselling during the rehabilitation period.

  19. Quantum information does not exist

    NASA Astrophysics Data System (ADS)

    Duwell, Armond

    Some physicists seem to believe that quantum information theory requires a new concept of information (Jozsa, 1998, Quantum information and its properties. In: Hoi-Kwong Lo, S. Popescu, T. Spiller (Eds.), Introduction to Quantum Computation and Information, World Scientific, Singapore, (pp. 49-75); Deutsch & Hayden, 1999, Information flow in entangled quantum subsystems, preprint quant-ph/9906007). I will argue that no new concept is necessary. Shannon's concept of information is sufficient for quantum information theory. Properties that are cited to contrast quantum information and classical information (i.e., Shannon information) actually point to differences in our ability to manipulate, access, and transfer information depending on whether quantum systems, opposed to classical systems, are used in a communication system. I also demonstrate that conceptually puzzling phenomena in quantum information theory, such as dense coding, teleportation, and Schumacher coding, all of which are cited as evidence that a new concept of information is required, do not have to be regarded as such.

  20. High-Fidelity Entangling Gates for Two-Electron Spin Qubits

    Cerfontaine, Pascal; Mehl, Sebastian; Divincenzo, David P.; Bluhm, Hendrik

    High fidelity gate operations for manipulating individual and multiple qubits are a prerequisite for fault-tolerant quantum information processing. Recently, we have shown that single-qubit gates for singlet-triplet qubits in GaAs can be pulse-engineered to reduce systematic errors and mitigate magnetic field fluctuations from the abundant nuclear spins, leading to experimentally demonstrated gate fidelities of 98.5%. We expect that a similar approach will be successful for two-qubit gates. We now describe short gating sequences for exchange-based two-qubit gates, showing that gate infidelities below 0.1% can be reached in realistic quantum dot setups. Additionally, we perform numerical pulse optimization to fully take the experimentally important imperfections into account, minimizing systematic errors and noise sensitivity. Since transferring the optimal control pulses to an experimental setting will inevitably incur systematic errors, we discuss how these errors can be calibrated on the experiment Supported by the Alexander von Humboldt Foundation, Alfried Krupp von Bohlen und Halbach Foundation, DFG Grant BL 1197/2- 1, and the Deutsche Telekom Foundation.

    The command line version of SeismicHandler (SH), a scientific analysis tool for seismic waveform data developed around 1990, has been redesigned in the recent years, based on a project funded by the Deutsche Forschungsgemeinschaft (DFG). The aim was to address new data access techniques, simplified metadata handling and a modularized software design. As a result the program was rewritten in Python in its main parts, taking advantage of simplicity of this script language and its variety of well developed software libraries, including ObsPy. SHX provides an easy access to waveforms and metadata via arclink and FDSN webservice protocols, also access to event catalogs is implemented. With single commands whole networks or stations within a certain area may be read in, the metadata are retrieved from the servers and stored in a local database. For data processing the large set of SH commands is available, as well as the SH scripting language. Via this SH language scripts or additional Python modules the command set of SHX is easily extendable. The program is open source, tested on Linux operating systems, documentation and download is found at URL "https://www.seismic-handler.org/".

    ABSTRACT Objective To describe the impact of the telemedicine application on the clinical process of care and its different effects on hospital culture and healthcare practice. Methods The concept of telemedicine through real time audio-visual coverage was implemented at two different hospitals in São Paulo: a secondary and public hospital, Hospital Municipal Dr. Moysés Deutsch, and a tertiary and private hospital, Hospital Israelita Albert Einstein. Results Data were obtained from 257 teleconsultations records over a 12-month period and were compared to a similar period before telemedicine implementation. For 18 patients (7.1%) telemedicine consultation influenced in diagnosis conclusion, and for 239 patients (92.9%), the consultation contributed to clinical management. After telemedicine implementation, stroke thrombolysis protocol was applied in 11% of ischemic stroke patients. Telemedicine approach reduced the need to transfer the patient to another hospital in 25.9% regarding neurological evaluation. Sepsis protocol were adopted and lead to a 30.4% reduction mortality regarding severe sepsis. Conclusion The application is associated with differences in the use of health services: emergency transfers, mortality, implementation of protocols and patient management decisions, especially regarding thrombolysis. These results highlight the role of telemedicine as a vector for transformation of hospital culture impacting on the safety and quality of care. PMID:26676268

    With Memoranda and other initiatives, the German Network for Health Service Research [Deutsches Netzwerk Versorgungsforschung e.V. (DNVF)] is fostering the methodological quality of care research studies for years. Compared to the standards of empirical research, questions concerning the role and function of theories, theoretical approaches and scientific principles have not been taken up on its own. Therefore, the DNVF e.V. has set up a working group in 2013, which was commissioned to prepare a memorandum on "theories in health care research". This now presented memorandum will primarily challenge scholars in health care services research to pay more attention to questions concerning the theoretical arsenal and the background assumptions in the research process. The foundation in the philosophy of science, the reference to normative principles and the theory-bases of the research process are addressed. Moreover, the memorandum will call on to advance the theorizing in health services research and to strengthen not empirical approaches, research on basic principles or studies with regard to normative sciences and to incorporate these relevant disciplines in health services research. Research structures and funding of health services research needs more open space for theoretical reflection and for self-observation of their own, multidisciplinary research processes.

    The exponential speed-up in some quantum algorithms is a direct result of parallel function-evaluation paths that interfere through a quantum Fourier transform (QFT). We report the implementation of a fully coherent QFT on five trapped Yb+ atomic qubits using sequences of fundamental quantum logic gates. These modular gates can be used to program arbitrary sequences nearly independent of system size and distance between qubits. We use this capability to first perform a Deutsch-Jozsa algorithm where several instances of three-qubit balanced and constant functions are implemented and then examined using single qubit QFTs. Secondly, we apply a fully coherent five-qubit QFT as a part of a quantum phase estimation protocol. Here, the QFT operates on a five-qubit superposition state with a particular phase modulation of its coefficients and directly produces the corresponding phase to five-bit precision. Finally, we examine the performance of the QFT in the period finding problem in the context of Shor's factorization algorithm. This work is supported by the ARO with funding from the IARPA MQCO program and the AFOSR MURI on Quantum Measurement and Verification.

    Quantum computers can solve certain problems more efficiently than any possible conventional computer. Small quantum algorithms have been demonstrated on multiple quantum computing platforms, many specifically tailored in hardware to implement a particular algorithm or execute a limited number of computational paths. Here we demonstrate a five-qubit trapped-ion quantum computer that can be programmed in software to implement arbitrary quantum algorithms by executing any sequence of universal quantum logic gates. We compile algorithms into a fully connected set of gate operations that are native to the hardware and have a mean fidelity of 98 per cent. Reconfiguring these gate sequences provides the flexibility to implement a variety of algorithms without altering the hardware. As examples, we implement the Deutsch-Jozsa and Bernstein-Vazirani algorithms with average success rates of 95 and 90 per cent, respectively. We also perform a coherent quantum Fourier transform on five trapped-ion qubits for phase estimation and period finding with average fidelities of 62 and 84 per cent, respectively.

  7. Evaluation of Improved Pushback Forecasts Derived from Airline Ground Operations Data

    Accurate and timely predictions of airline pushbacks can potentially lead to improved performance of automated decision-support tools for airport surface traffic, thus reducing the variability and average duration of costly airline delays. One factor which affects the realization of these benefits is the level of uncertainty inherent in the turn processes. To characterize this inherent uncertainty, three techniques are developed for predicting time-to-go until pushback as a function of available ground-time; elapsed ground-time; and the status (not-started/in-progress/completed) of individual turn processes (cleaning, fueling, etc.). These techniques are tested against a large and detailed dataset covering approximately l0(exp 4) real-world turn operations obtained through collaboration with Deutsche Lufthansa AG. Even after the dataset is filtered to obtain a sample of turn operations with minimal uncertainty, the standard deviation of forecast error for all three techniques is lower-bounded away from zero, indicating that turn operations have a significant stochastic component. This lower-bound result shows that decision-support tools must be designed to incorporate robust mechanisms for coping with pushback demand stochasticity, rather than treating the pushback demand process as a known deterministic input.

    We present new Nusselt-number (Nu) measurements for slowly rotating turbulent thermal convection in cylinders with aspect ratio Γ = 1 . By using compressed gasses and various liquids, we now have data in the Prandtl number (Pr) range 0 . 74 < Pr < 35 . 5 and for Rayleigh numbers (Ra) in the range 4 ×108 < Ra < 2 ×1011 . With these data we investigate in detail the effect of Pr and Ra on the heat-transport enhancement close to its onset. This enhancement takes place for rotation rates larger than a critical value, as expressed by the dimensionless inverse Rossby number (1 / Ro), since only then vortices form, in which due to Ekman pumping fluid is transported from the thermal boundary layers into the turbulent bulk. We found that the critical inverse Rossby number (1 / Roc) decreases with increasing Pr, following a power law with exponent α = - 0 . 40 +/- 0 . 02 . For larger rotation rates, the relative heat transport enhancement (Nur) increases first linearly with a slope S = ∂Nur / ∂ (1 / Ro) . We show that also the slope S follows a power law S ~ Prβ Raγ with β = - 0 . 10 +/- 0 . 06 and γ = - 0 . 14 +/- 0 . 04 . We found that the maximum heat transport enhancement (up to 40%) increases with increasing Pr and decreasing Ra. This work was supported by NSF-Grant DMR11-58514.

    A novel application of the correlation matrix formalism to study dynamics of the financial evolution is presented. This formalism allows to quantify the memory effects as well as some potential repeatable intraday structures in the financial time series. The present study is based on the high-frequency Deutsche Aktienindex (DAX) data over the time period between November 1997 and December 1999 and demonstrates a power of the method. In this way, two significant new aspects of the DAX evolution are identified: (i) the memory effects turn out to be sizably shorter than what the standard autocorrelation function analysis seems to indicate and (ii) there exist short term repeatable structures in fluctuations that are governed by a distinct dynamics. The former of these results may provide an argument in favour of the market efficiency while the latter one may indicate origin of the difficulty in reaching a Gaussian limit, expected from the central limit theorem, in the distribution of returns on longer time horizons.

    The Seventeenth International Microgravity Measurements Group (MGMG) meeting was held 24-26 March 1998 at the Ohio Aerospace Institute (OAI) in Brook Park, Ohio. This meeting focused on the transition of microgravity science research from the Shuttle, Mir, and free flyers to the International Space Station. The MGMG series of meetings are conducted by the Principal Investigator Microgravity Services project of the Microgravity Science Division at the NASA Lewis Research Center. The MGMG meetings provide a forum for the exchange of information and ideas about the microgravity environment and microgravity acceleration research in the Microgravity Research Program. The meeting had participation from investigators in all areas of microgravity research. The attendees included representatives from: NASA centers; National Space Development Agency of Japan; European Space Agency; Daimler Benz Aerospace AG; Deutsches Zentrum fuer Luft- und Raumfahrt; Centre National d'Etudes Spatiales; Canadian Space Agency, national research institutions; Universities in U.S., Italy, Germany, and Russia; and commercial companies in the U.S. and Russia. Several agencies presented summaries of the measurement, analysis, and characterization of the microgravity environment of the Shuttle, Mir, and sounding rockets over the past fifteen years. This extensive effort has laid a foundation for pursuing a similar course during future microgravity science experiment operations on the ISS. Future activities of microgravity environment characterization were discussed by several agencies who plan to operate on the ISS.

    The Kanzelhöhe Observatory (KSO) was founded during World War II by the Deutsche Luftwaffe (German Airforce) as one station of a network of observatories that were set up to provide information on solar activity in order to better assess the actual conditions of the Earth's ionosphere in terms of radio-wave propagation. Solar observations began in 1943 with photographs of the photosphere and drawings of sunspots, plage regions, and faculae, as well as patrol observations of the solar corona. At the beginning, all data were sent to Freiburg (Germany). After WW II, international cooperation was established and the data were sent to Zurich, Paris, Moscow, and Greenwich. Relative sunspot numbers have been derived since 1944. The agreement between relative sunspot numbers derived at KSO and the new International Sunspot Number (ISN) (SILSO World Data Center in International Sunspot Number Monthly Bulletin and online catalogue, 1945 - 2015) lies within {≈} 10 %. However, revisiting the historical data, we also find periods with larger deviations. The reasons for the deviations were twofold: On the one hand, a major instrumental change took place during which the instrument was relocated and modified. On the other hand, a period of frequent replacements of personnel caused significant deviations; this clearly shows the importance of experienced observers. In the long term, the instrumental improvements led to better image quality. Additionally, we find a long-term trend towards better seeing conditions that began in 2000.

    The German Data Center for the Solar Dynamics Observatory (GDC-SDO), hosted by the Max Planck Institute for Solar System Research in Germany, will provide access to SDO data for the German solar physics community. The GDC-SDO will make available all the relevant Helioseismic and Magnetic Imager (HMI) data for helioseismology and smaller se- lected Atmospheric Imaging Assembly (AIA) data sets. This project commenced in August 2007 and is funded by the German Aerospace Center (Deutsches zentrum fuer Luft- und Raumfahrt or DLR) until December 2012. An important component of the GDC-SDO is the Data Record Management System (DRMS), developed in collaboration with the Stan- ford/Lockheed Joint Science Operations Center (JSOC). The PEGASUS workflow manage- ment system will be used to implement GDC-SDO data analysis pipelines. This makes use of the CONDOR High Throughput Computing Project for optimal job scheduling and also the GLOBUS Toolkit to enable grid technologies. Additional information about the GDC-SDO can be found at http://www.mps.mpg.de/projects/seismo/GDC1/index.html. Here, we sug- gest a similar structure and philosophy should be ideal for the PLATO mission, which looks for planetary transits and stellar oscillations and is being studied by ESA for an M-Mission slot in Cosmic Vision.

    Between October 1974 and October 1978 23 children with acute myelocytic leucemia (AML) received intensive therapy in the Univ.-Kinderklinik Münster: 4 children were treated according to the ALGB-protocol consisting of 5-7 day courses of ARA-C-infusion and 3 DNR-injections. 19 patients received the West-Berlin-protocol: The first 7 the original ALL protocol, 11 the modified form of AML, which will be presented here as AML-therapy-study BFM 78. 4 of the 23 patients died with early acute cerebral bleeding. 2 patients were nonresponders. 17 children went into remission. One girl died in remission of septicemic aspergillosis. 4 children had a relapse. In November 1978 there were still 12 patients in continuous complete remission, 3 of them already without therapy. 13 of the 19 patients, who were treated with the West-Berlin-protocol went into remission. 1 had a relapse. At present there are 11 patients in continuous complete remission. The above results and those found in the literature could signify that the long term prognosis of children with AML will be improved. To coordinate efforts toward this goal a cooperative AML-therapy-study in the "Deutsche Arbeitsgemeinschaft für Leukämieforschung" (BFM-group) using the here presented therapy protocol was formed in November 1978.

    Space flight is associated with the loss of skeletal muscle, principally from muscles with anti-gravity functions. Examination of data across different missions can permit a distinction to be made between true microgravity responses and what are mission-specific responses. Protein metabolism has been investigated on six missions, four short-term [Shuttle missions Space Life Sciences 1 (1991, SLSI), Space Life Sciences 2 (1993, SLS2), Deutsche-2 (1993, D2) and the Life and Microgravity Sciences (1996, LMS)] and two long-term missions (Skylab 1993 and NASA/MIR, 1996-1998). Measurements made include dietary intake (six missions), nitrogen balance (four missions), whole-body protein kinetics with [15N]glycine as the tracer (four missions) and cortisol excretion (three missions). Also available for comparison are bed rest studies with and without exercise. The purpose of this paper is to see what can be learnt about the muscle loss problem by comparing metabolic results across the six missions for which data are available and against bed rest. The analysis suggests that there is a linkage between the inability to maintain energy balance and exercise, and the connection is the decreased efficiency of removal of the metabolic by-products of exercise (heat, CO2) during space flight.

    Alberto Fragio is currently one of the major experts on Hans Blumenberg's work and thought. In recent years he has become a great interpreter of Blumenberg's posthumous publications and his Nachlaβ at the Deutsche Literatur-Archiv Marbach (DLA Marbach). Since he acquired his doctoral degree in 2007, Fragio has devoted much of his efforts to clarifying Blumenberg's convoluted philosophical corpus, whose understanding - as is known - is really demanding for anyone who ventures into its disclosure, and it requires a monumental exercise of patience. Fragio has published far more than a dozen academic articles and three monographs, all of them generally pointing to the existence of a holistic nature in the philosophical work to which Blumenberg devoted a lifetime.

Initiativen zum Umweltschutz, 13 ed., Deutsche Bundesstiftung Ulmwelt, Erich Schmidt, Berlin), the Bavarian State Office for Environmental Protection performs emission measurements at thermal waste treatment plants to optimize operation, to accompany and support development of new technologies, and to study the effect of this kind of waste treatment technology on the environment. Based on recent studies (October 1995-July 1999) at six municipal solid waste incinerators (MSWI) in Bavaria all emission streams (solid and gas) are characterized with respect to organic pollutant contents and compared to the emissions of waste pyrolysis. The significant ranges of pollutant concentration as well as the specific congener patterns observed are similar for all MSWI, regardless of differences in technical design and waste input, but differ markedly from those of the pyrolysis products. The overall approach, including the sampling of all output streams and the determination of mass streams and volume flow rates, allows the calculation of the total output of different organic pollutants for waste incineration plants aand to estimate the relative contribution of each of the emission streams to the total pollutant load. Removal efficiencies are also calculated for the air pollution control (APC) systems of the different MSWI plants.

    The Marchfeld basin with a size of approximately 1000 km2 represents the Austrian "granary". To prevent shortage of water as a result of increased ground water removal for irrigation, industrial purposes and drinking water supply, a canal being 18 km in length was constructed from the Danube to the center of the Marchfeld. From there, water is further distributed via two creeks (Russbach and Stempfelbach). This study was intended to evaluate whether the surface water of the Marchfeld canal system can be classified into hygienic-microbiological categories as proposed by DIN (Deutsche Industrienorm) standards for irrigation water. For this purpose, water sampled monthly from three different sampling sites from 1996 to 1999 was examined for E. coli and enterococci. In addition, water samples were examined for salmonella twice a year from 1996 to 1998 and for cryptosporidia six times during the year 1999. Though the water showed varying degrees of fecal load, the results of the examinations revealed that only one of the three sampling sites showed constant quality levels according to the DIN classification system over prolonged periods of time. However, exceeding of the limit values was occasionally observed indicating the need for regular bacteriological examinations. The high variation of the results from the other sampling sites hardly permits a definite classification in one of the quality classes. PMID:11556148

    Numerous courses on alternative medicine are regularly advertised in Deutsches Arzteblatt, the organ of the German Medical Association. The present German legislation likewise supports this form of medicine, and this explains why Iscador, an extract of the mistletoe, is found in the Rote Liste, a directory of commercially available medical drugs, under the heading "cytostatic and antimetastatic drugs" although such beneficial effect is unproven. To give another example, a German health insurance fund was sentenced to pay for acupuncture as a treatment for hepatic failure. This judgement is characteristic of the present German judicial system and represents a victory of "oracling irrationalism" (Popper). The astonishing popularity of alternative medicine can be explained by a revival of romanticism. An intellectually fair opposite position has been delineated by Karl Popper in the form of critical rationalism. It is important to realize, however, that our decision to adhere to rational thinking is made in the innermost depth of our heart but not on the basis of rational arguing. Rather, the decision in favor of reason has a moral dimension. PMID:10907162

    Little is known on the role of the senses smell and taste in end-of-life care. The presented systematic literature analysis investigates the significance of smell and taste in palliative care. The online databases PubMed, CINAHL, MEDLINE, Deutsche Nationalbibliothek and British National Library were searched for English and German literature published between 1970 and April 2013 containing any kind of original data on the impact of smell and taste in patients in a palliative care situation. All retrieved publications were screened for relevance and full text was obtained for all articles identified as relevant. We integrated 13 papers for further analysis (explorative surveys 5, clinical trials 3, case studies 2, qualitative study 1, brief report 1, clinical report 1). Prevalence of smell and taste alterations in palliative care ranges between 60 and 86%. Existing literature reflects the significance of smells and tastes in palliative care setting in two main streams--smell and taste alterations as symptoms and malodorous wounds. Prevalence of smell and taste alterations in palliative care is high. However, in palliative care literature concepts for the assessment and fostering of subjective significance of smell and taste and the individual impact of significant smells and tastes are predominantly neglected. Available instruments should be characterized, validated and adapted for the use for palliative care patients.

    In a combined approach of extensive measurement and accompanying simulation a wind turbine blade used in the 1.5 MW class was investigated for improvement of aerodynamic properties and especially the energy yield. One blade was dismantled and its geometry was locally measured by a specially designed laser scanning-system. From this geometry data set five 2D wind tunnel models were manufactured and measured in the wind tunnel of Deutsche Wind Guard Engineering GmbH at Bremerhaven, Germany. In addition, extensive CFD investigations were performed to investigate the usefulness of so-called aerodynamic devices like vortex generators, Gurney flaps and others for improving energy yield. As a result it could be shown that the aerodynamic efficiency of the manufactured blades - if measured in terms of lift-to-drag ratio - is at a high level but still can be further improved. 3D CFD investigations were able to show the influence of Gurney flaps and boundary layer fences and their interactions.

    Assisted suicide is allowed in 3 states of the United States (Oregon, Washington, Montana) but only if performed by a physician.On the opposite, in Switzerland, at the beginning of the 20th century, the Swiss Penal Code referred to assisted suicide in the context of honor or an unhappy love affair. It was only in 1985 that Exit Deutsche Schweiz (Exit for German-speaking Switzerland) "medically" assisted the first patient to end his life.Even if authorized by the Swiss law upon certain conditions, assisted suicide is subject to debates for ethical reasons. The Swiss Academy of Medical Sciences described directives to guide physicians on this difficult subject.Different studies showed an increase in the number of medical-assisted suicide in Switzerland since the 1990s. Now, this number seems to be quite stable. Assisted suicide is authorized in a few hospitals under strict conditions (especially when returning home is impossible).Thus, according to the Swiss law, any person could perform assisted suicide; this is essentially performed by 3 main associations, using pentobarbital on medical prescription as lethal substance.Generally speaking, the Swiss population is rather in favor of assisted suicide. Among politics, the debate has been tough until 2010, when the Federal Council decided not to modify the Swiss Penal Code concerning assisted suicide.

    Aerosols of the volcanic degassing plumes from Mt. Etna and Mt. Stromboli were probed with in situ instruments on board the Deutsches Zentrum für Luft- und Raumfahrt research aircraft Falcon during the contrail, volcano, and cirrus experiment CONCERT in September 2011. Aerosol properties were analyzed using angular-scattering intensities and particle size distributions measured simultaneously with the Polar Nephelometer and the Forward Scattering Spectrometer probes (FSSP series 100 and 300), respectively. Aerosols of degassing plumes are characterized by low values of the asymmetry parameter (between 0.6 and 0.75); the effective diameter was within the range of 1.5-2.8 µm and the maximal diameter was lower than 20 µm. A principal component analysis applied to the Polar Nephelometer data indicates that scattering features of volcanic aerosols of different crater origins are clearly distinctive from angular-scattering intensities of cirrus and contrails. Retrievals of aerosol properties revealed that the particles were "optically spherical" and the estimated values of the real part of the refractive index are within the interval from 1.35 to 1.38. The interpretation of these results leads to the conclusion that the degassing plume aerosols were porous with air voids. Our estimates suggest that aerosol particles contained about 18 to 35 % of air voids in terms of the total volume.

    The utilization of fermentation media derived from waste and by-product streams from biodiesel and confectionery industries could lead to highly efficient production of bacterial cellulose. Batch fermentations with the bacterial strain Komagataeibacter sucrofermentans DSM (Deutsche Sammlung von Mikroorganismen) 15973 were initially carried out in synthetic media using commercial sugars and crude glycerol. The highest bacterial cellulose concentration was achieved when crude glycerol (3.2 g/L) and commercial sucrose (4.9 g/L) were used. The combination of crude glycerol and sunflower meal hydrolysates as the sole fermentation media resulted in bacterial cellulose production of 13.3 g/L. Similar results (13 g/L) were obtained when flour-rich hydrolysates produced from confectionery industry waste streams were used. The properties of bacterial celluloses developed when different fermentation media were used showed water holding capacities of 102–138 g·water/g·dry bacterial cellulose, viscosities of 4.7–9.3 dL/g, degree of polymerization of 1889.1–2672.8, stress at break of 72.3–139.5 MPa and Young’s modulus of 0.97–1.64 GPa. This study demonstrated that by-product streams from the biodiesel industry and waste streams from confectionery industries could be used as the sole sources of nutrients for the production of bacterial cellulose with similar properties as those produced with commercial sources of nutrients.

    Regarding epilepsy several new developments can be reported. The International League Against Epilepsy (ILAE) has suggested a new definition of epilepsy, for the first time including a definition of epilepsy resolution. Progress in the diagnosis relates to new genetic findings, improvements in magnetic resonance imaging (MRI) and the increasing use of stereo electroencephalograms (sEEG). Regarding treatment there are new clinically relevant data on the pathophysiology and prevention of sudden unexpected death in epilepsy (SUDEP). Zonisamide has been approved by the European Medicines Agency (EMA) for monotherapy in adults with focal seizures and combination therapy in children aged ≥ 6 years. Retigabin and perampanel have been approved but are currently taken off the market in Germany (only) because the Gemeinsamer Bundesausschuss (GBA, Joint Federal Committee) did not find any additional therapeutic value as compared to lamotrigine due to a lack of data. A decision regarding a new application for perampanel is pending. Regarding surgical treatment novel ablation techniques (e.g. stereotactic radiofrequency and laser ablation as well as focussed ultrasound ablation) and brain stimulation paradigms are under investigation. Experimental studies, generously supported by the European Union (EU) and the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) are focusing on (opto-)genetic (e.g. using lentoviral transfection), epigenetic (e.g. micro-RNA-related) approaches and on the investigation of neuronal micronetworks.

    Historical research has hitherto focused on the specific contribution of human genetics research to National Socialist racial hygiene. During the Third Reich this field had a key position and received very substantial financial support from the government. However, this state sponsorship during the Nazi period was not constant, as documents from the most important public funding organizations for academic research in Germany, the German Research Foundation (Deutsche Forschungsgemeinschaft) and the Reich Research Council (Reichsforschungsrat) show. Human genetics saw a reduction in sponsorship as the government shifted its spending towards preparations for the war. Accordingly, many human geneticists and racial hygienists were unable to continue their research or were forced to change the focus of their work. It is also important to note that much of the available funds were concentrated on the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics. This essay analyzes the institutional context of science policy as well as the dynamics between the science of human heredity and Nazi politics during the war.

  6. Constructor theory of probability

    Unitary quantum theory, having no Born Rule, is non-probabilistic. Hence the notorious problem of reconciling it with the unpredictability and appearance of stochasticity in quantum measurements. Generalizing and improving upon the so-called `decision-theoretic approach', I shall recast that problem in the recently proposed constructor theory of information-where quantum theory is represented as one of a class of superinformation theories, which are local, non-probabilistic theories conforming to certain constructor-theoretic conditions. I prove that the unpredictability of measurement outcomes (to which constructor theory gives an exact meaning) necessarily arises in superinformation theories. Then I explain how the appearance of stochasticity in (finitely many) repeated measurements can arise under superinformation theories. And I establish sufficient conditions for a superinformation theory to inform decisions (made under it) as if it were probabilistic, via a Deutsch-Wallace-type argument-thus defining a class of decision-supporting superinformation theories. This broadens the domain of applicability of that argument to cover constructor-theory compliant theories. In addition, in this version some of the argument's assumptions, previously construed as merely decision-theoretic, follow from physical properties expressed by constructor-theoretic principles.

  7. Safety relevant knowledge of orally anticoagulated patients without self-monitoring: a baseline survey in primary care

    2014-01-01

    Background Effective and safe management of oral anticoagulant treatment (OAT) requires a high level of patient knowledge and adherence. The aim of this study was to assess patient knowledge about OAT and factors associated with patient knowledge. Methods This is a baseline survey of a cluster-randomized controlled trial in 22 general practices with an educational intervention for patients or their caregivers. We assessed knowledge about general information on OAT and key facts regarding nutrition, drug-interactions and other safety precautions of 345 patients at baseline. Results Participants rated their knowledge about OAT as excellent to good (56%), moderate (36%) or poor (8%). However, there was a discrepancy between self-rated knowledge and evaluated actual knowledge and we observed serious knowledge gaps. Half of the participants (49%) were unaware of dietary recommendations. The majority (80%) did not know which non-prescription analgesic is the safest and 73% indicated they would not inform pharmacists about OAT. Many participants (35-75%) would not recognize important emergency situations. After adjustment in a multivariate analysis, older age and less than 10 years education remained significantly associated with lower overall score, but not with self-rated knowledge. Conclusions Patients have relevant knowledge gaps, potentially affecting safe and effective OAT. There is a need to assess patient knowledge and for structured education programs.

    Acoustic data taken in the anechoic Deutsch-Niederlaendischer Windkanal (DNW) have documented the blade vortex interaction (BVI) impulsive noise radiated from a 1/7-scale model main rotor of the AH-1 series helicopter. Averaged model scale data were compared with averaged full scale, inflight acoustic data under similar nondimensional test conditions. At low advance ratios (mu = 0.164 to 0.194), the data scale remarkable well in level and waveform shape, and also duplicate the directivity pattern of BVI impulsive noise. At moderate advance ratios (mu = 0.224 to 0.270), the scalig deteriorates, suggesting that the model scale rotor is not adequately simulating the full scale BVI noise; presently, no proved explanation of this discrepancy exists. Carefully performed parametric variations over a complete matrix of testing conditions have shown that all of the four governing nondimensional parameters - tip Mach number at hover, advance ratio, local inflow ratio, and thrust coefficient - are highly sensitive to BVI noise radiation.

    This report represents a general theory applicable to axial, radial, and mixed flow turbomachines operating at subsonic and supersonic speeds with a finite number of blades of finite thickness. References reflect the evolution of computational methods used, from the inception of the theory in the 50's to the high-speed computer era of the 90's. Two kinds of relative stream surfaces, S(sub 1) and S(sub 2), are introduced for the purpose of obtaining a three-dimensional flow solution through the combination of two-dimensional flow solutions. Nonorthogonal curvilinear coordinates are used for the governing equations. Methods of computing transonic flow along S(sub 1) and S(sub 2) stream surfaces are given for special cases as well as for fully three-dimensional transonic flows. Procedures pertaining to the direct solutions and inverse solutions are presented. Information on shock wave locations and shapes needed for computations are discussed. Experimental data from a Deutsche Forschungs- und Versuchsanstalt fur Luft- und Raumfahrt e.V. (DFVLR) rotor and from a Chinese Academy of Sciences (CAS) transonic compressor rotor are compared with the computed flow properties.

    The Stratospheric Observatory For Infrared Astronomy (SOFIA) is an airborne observatory consisting of a specially modified Boeing 747SP with a 2.7 m telescope, flying at altitudes as high as 13.7 km (45,000 ft). Designed to observe at wavelengths from 0.3 {mu}m to 1.6 mm, SOFIA operates above 99.8% of the water vapor that obscures much of the infrared and submillimeter. SOFIA has seven science instruments under development, including an occultation photometer, near-, mid-, and far-infrared cameras, infrared spectrometers, and heterodyne receivers. SOFIA, a joint project between NASA and the German Aerospace Center Deutsches Zentrum fuer Luft und-Raumfahrt, began initial science flights in 2010 December, and has conducted 30 science flights in the subsequent year. During this early science period three instruments have flown: the mid-infrared camera FORCAST, the heterodyne spectrometer GREAT, and the occultation photometer HIPO. This Letter provides an overview of the observatory and its early performance.

The concept enrichment of the drug from the gas phase and detection by immunological means. This publication covers the development of specific antibodies and various detection procedures. Antibodies with a high affinity for cocaine have been developed with the aid of specially synthesized immunogens. A competitive detection procedure with biosensors based on optical grating couplers and applying particulate labels has been established, showing a lower detection limit of 10-10 mol/l for cocaine. Additionally, a combination of a displacement-immunoreactor and an enzymatically amplified electrode was investigated, which at present still suffers from insufficient sensitivity of the immunoreactor. An alternative, fleece-matrix based test procedure, where enrichment and detection steps are integrated in a single unit, is promising in terms of simplicity and sensitivity. A simple swab-test for the detection of cocaine at surfaces has been developed, which has a lower detection limit of about 10 ng and which can be performed within one minute.

  14. Condensation and transport in the totally asymmetric inclusion process (TASIP)

    NASA Astrophysics Data System (ADS)

    Knebel, Johannes; Weber, Markus F.; Krueger, Torben; Frey, Erwin

    Transport phenomena are often modeled by the hopping of particles on regular lattices or networks. Such models describe, e.g., the exclusive movement of molecular motors along microtubules: no two motors may occupy the same site. In our work, we study inclusion processes that are the bosonic analogues of the fermionic exclusion processes. In inclusion processes, many particles may occupy a single site and hopping rates depend linearly on the occupation of departure and arrival sites. Particles thus attract other particles to their own site. Condensation occurs when particles collectively cluster in one or multiple sites, whereas other sites become depleted.We showed that inclusion processes describe both the selection of strategies in evolutionary zero-sum games and the condensation of non-interacting bosons into multiple quantum states in driven-dissipative systems. The condensation is captured by the antisymmetric Lotka-Volterra equation (ALVE), which constitutes a nonlinearly coupled dynamical system. We derived an algebraic method to analyze the ALVE and to determine the condensates. Our approach allows for the design of networks that result in condensates with oscillating occupations, and yields insight into the interplay between network topology and transport properties.

  15. Thermodynamic properties of water solvating biomolecular surfaces

    NASA Astrophysics Data System (ADS)

    Heyden, Matthias

    Changes in the potential energy and entropy of water molecules hydrating biomolecular interfaces play a significant role for biomolecular solubility and association. Free energy perturbation and thermodynamic integration methods allow calculations of free energy differences between two states from simulations. However, these methods are computationally demanding and do not provide insights into individual thermodynamic contributions, i.e. changes in the solvent energy or entropy. Here, we employ methods to spatially resolve distributions of hydration water thermodynamic properties in the vicinity of biomolecular surfaces. This allows direct insights into thermodynamic signatures of the hydration of hydrophobic and hydrophilic solvent accessible sites of proteins and small molecules and comparisons to ideal model surfaces. We correlate dynamic properties of hydration water molecules, i.e. translational and rotational mobility, to their thermodynamics. The latter can be used as a guide to extract thermodynamic information from experimental measurements of site-resolved water dynamics. Further, we study energy-entropy compensations of water at different hydration sites of biomolecular surfaces.

    2007-11-01

    The nonlinear nature of the rf absorption in a helicon-produced plasma was investigated on the helicon device HE-L [1] with the aid of a double pulse technique providing high and low amplitude helicon propagation under nearly identical conditions. Time- and space-resolved (2D) measurements of the rf magnetic field (amplitude and phase of all components) were carried out by means of a B-dot probe array. For high rf power, a small narrow peak arises on top of the density profile close to the axis leading to focusing of the rf field energy and the rf power deposition. Nevertheless, in accordance with the linear helicon theory for a non-uniform plasma, the axial wavenumber remains nearly the same as for low power. The rf power deposition in the core of the helicon discharge deduced from the energy flux balance was compared with that obtained from the rf field distribution assuming collisional absorption. It turns out that collisions are by far not sufficient to account for the absorption of helicon modes, particularly for high rf power. Nonlinear processes, most likely associated with the parametric excitation of electrostatic fluctuations [2], are thus involved.- This work was supported by the Deutsche Forschungsgemeinschaft (Sonderforschungsbereich 591, Project A7).- [1] M.

  17. A Separable, Dynamically Local Ontological Model of Quantum Mechanics

    2016-01-01

    A model of reality is called separable if the state of a composite system is equal to the union of the states of its parts, located in different regions of space. Spekkens has argued that it is trivial to reproduce the predictions of quantum mechanics using a separable ontological model, provided one allows for arbitrary violations of `dynamical locality'. However, since dynamical locality is strictly weaker than local causality, this leaves open the question of whether an ontological model for quantum mechanics can be both separable and dynamically local. We answer this question in the affirmative, using an ontological model based on previous work by Deutsch and Hayden. Although the original formulation of the model avoids Bell's theorem by denying that measurements result in single, definite outcomes, we show that the model can alternatively be cast in the framework of ontological models, where Bell's theorem does apply. We find that the resulting model violates local causality, but satisfies both separability and dynamical locality, making it a candidate for the `most local' ontological model of quantum mechanics.

    The conversion of the PETRA storage ring at the Deutsches Elektronen Synchrotron (DESY) to the third generation synchrotron radiation light source PETRAIII [1] poses a challenge to the design of the beamline transport system. One of these challenges is to supply 14 beamlines and experiments windowless with the extremely collimated undulator radiation from the storage ring. The windowless connection includes the risk of accidental venting of the storage ring by experiments connected to the beamlines. To stop the inrush of such an accidental venting fast closing shutter (FCS) systems with closing times in the 10msec range are mandatory. The strong radiation background in the storage ring tunnel requires the installation of all metal valves. A new small fast closing shutter with an aperture of 40mm fitting to the strong collimated undulator beams and with a closing time < 10msec was developed. The all metal sealing principle achieves leak rates smaller than 10mbarl/sec. This leak rate of the fast closing shutter combined with a standard all metal valve prevents venting of the storage ring and the beam time losses for all users. The mechanical and electronic layouts as well as first experiences with the new fast closing shutter system developed for PETRAIII are presented.

    After Freud proposed in 1918 the creation of "institutions or out-patient clinics [where] treatment will be free," Max Eitingon, Ernst Simmel, and other progressive psychoanalysts founded the Berlin Poliklinik, a free outpatient clinic. Guided by Weimar Republic principles of "radical functionalism," the Poliklinik and its companion inpatient service, the Schloss Tegel Sanatorium, pioneered treatment and training methodologies still used--and still debated--today. Their funding strategies, statistics, and approaches to clinical problems like length of treatment tell the history of an innovative psychoanalytic institute where men and women were generally treated in equal numbers and patients (ranging in occupational status from unemployed to professional) of all ages were treated free. Franz Alexander, Karl Abraham, Theresa Benedek, Paul Federn, Otto Fenichel, Edith Jacobson, Karen Horney, Erich Fromm, Helene Deutsch, Hanns Sachs, Sándor Radó, Hermine von Hug-Hellmuth, Wilhelm Reich, Annie Reich, and Melanie Klein all worked at the Poliklinik, and from there initiated decades of original clinical theory, practice, and education.
