    Dr. Jerzy Dobrzanski was born in Warsaw in 1889. He attended grade school and graduated from high school there. He began medical studies and graduated from the Jagiellonian University in Krakow in 1914. He served as a surgeon in the Russian Army during World War I. He passed his final medical degree examination in 1921. He specialized in gynecology and obstetrics at Wilno University. From 1923 to 1939, he was head of the obstetrics and gynecology department of the Railway Hospital in Wilno. He became actively involved in social issues and the independence cause as a young pupil, for which he was persecuted. During World War II, he was one of the leaders of the Polish underground resistance movement in the Wilno region. He was sentenced to hard labor in the Soviet gulag, where he stayed from 1945-1956. Upon his return to Poland, dr. Jerzy Dobranski lived and worked as a gynecologist for the Polish Railway in Wroclaw. He died in 1970. PMID:11625807

    In this talk we examine how high performance computing has changed over the last 10-year and look toward the future in terms of trends. These changes have had and will continue to have a major impact on our software. A new generation of software libraries and lgorithms are needed for the effective and reliable use of (wide area) dynamic, distributed and parallel environments. Some of the software and algorithm challenges have already been encountered, such as management of communication and memory hierarchies through a combination of compile--time and run--time techniques, but the increased scale of computation, depth of memory hierarchies, range of latencies, and increased run--time environment variability will make these problems much harder. We will focus on the redesign of software to fit multicore architectures.

    NASA Technical Reports Server (NTRS)

    2000-01-01

    NASA is looking to biological techniques that are millions of years old to help it develop new materials and nanotechnology for the 21st century. Sponsored by NASA, Jerzy Bernholc, a principal investigator in the microgravity materials science program and a physics professor at North Carolina State University, Bernholc works with very large-scale computations to model carbon molecules as they assemble themselves to form nanotubes. The strongest confirmed material known, nanotubes are much stronger than graphite, a more common material made of carbon, and weigh six times less than steel. Nanotubes have potential uses such as strain gauges, advanced electronic devices, amd batteries. The strength, light weight, and conductive qualities of nanotubes, shown in light blue in this computed electron distribution, make them excellent components of nanoscale devices. One way to conduct electricity to such devices is through contact with aluminum, shown in dark blue.

    Some reevaluations concerning the biography of the physicist Mihail Alexandrovici Pavlov (Pawlow)(1884, Bulboaca, Bessarabia -1961, Kishinev, Moldavian S.S.R.) are made concerning his eventual collaboration with NKVD (KGB) since the second half of the 20-th till 1949 and since 1953 till 1961. A comparison is made with the famous statistician and mathematician, astronomer and sociologist Jerzy Neyman (1894, Bendery (Tighina), Bessarabia-1981, Los Angeles, USA) is made to show the collaboration of Pavlov (Pawlow) with Soviet NKVD. The conflicts with another great Soviet Physicists, the Academician Mihail Alexandrovich Leontovich, one of the closest collaborators of Lev D. Landau gives us another arguments. Other problems of general interest are also examined.

  19. Predicting the Electronic Properties of 3D, Million-atom Semiconductor nanostructure Architectures

    2012-03-15

    This final report describes the work done by Jack Dongarra (University Distinguished Professor) and Stanimire Tomov (Research Scientist) related to the DOE project entitled Predicting the Electronic Properties of 3D, Million-Atom Semiconductor Nanostructure Architectures. In this project we addressed the mathematical methodology required to calculate the electronic and transport properties of large nanostructures with comparable accuracy and reliability to that of current ab initio methods. This capability is critical for further developing the field, yet it is missing in all the existing computational methods. Additionally, quantitative comparisons with experiments are often needed for a qualitative understanding of the physics, and for guiding the design of new nanostructures. We focused on the mathematical challenges of the project, in particular on solvers and preconditioners for large scale eigenvalue problems that occur in the computation of electronic states of large nanosystems. Usually, the states of interest lie in the interior of the spectrum and their computation poses great difficulties for existing algorithms. The electronic properties of a semiconductor nanostructure architecture can be predicted/determined by computing its band structure. Of particular importance are the 'band edge states' (electronic states near the energy gap) which can be computed from a properly defined interior eigenvalue problem. Our primary mathematics and computational challenge here has been to develop an efficient solution methodology for finding these interior states for very large systems. Our work has produced excellent results in terms of developing both new and extending current state-of-the-art techniques.

  20. Recognizing Sights, Smells, and Sounds with Gnostic Fields

    Kanan, Christopher

    2013-01-01

    Mammals rely on vision, audition, and olfaction to remotely sense stimuli in their environment. Determining how the mammalian brain uses this sensory information to recognize objects has been one of the major goals of psychology and neuroscience. Likewise, researchers in computer vision, machine audition, and machine olfaction have endeavored to discover good algorithms for stimulus classification. Almost 50 years ago, the neuroscientist Jerzy Konorski proposed a theoretical model in his final monograph in which competing sets of “gnostic” neurons sitting atop sensory processing hierarchies enabled stimuli to be robustly categorized, despite variations in their presentation. Much of what Konorski hypothesized has been remarkably accurate, and neurons with gnostic-like properties have been discovered in visual, aural, and olfactory brain regions. Surprisingly, there have not been any attempts to directly transform his theoretical model into a computational one. Here, I describe the first computational implementation of Konorski's theory. The model is not domain specific, and it surpasses the best machine learning algorithms on challenging image, music, and olfactory classification tasks, while also being simpler. My results suggest that criticisms of exemplar-based models of object recognition as being computationally intractable due to limited neural resources are unfounded. PMID:23365648

    Konorski, Jerzy

    2013-01-01

    The manuscript printed below has been written by Professor Jerzy Konorski around 1970, a few years before his death in 1973. The manuscript has not been published before. It was recently discovered in Konorski's papers deposed in the Library of the Nencki Institute of Experimental Biology. In his critical review Konorski debates advantages and shortcomings of the physiological approach of Pavlov and purely behavioristic approaches advocated by Hull and Skinner. He supports close cooperation o behaviorists with neurophysiologists and neuroanatomists, with focus on the investigation of the neural mechanisms underlying behavior. Konorski's ideas concerning the integration of the study of behavior and neurophysiology anticipated contemporary path of neuroscience. Indeed, his approach, which at that time appeared somewhat controversial, is universally accepted by contemporary neuroscientists. By contrast, physiological theories of higher mental functions formulated by Pavlov as well as deliberately anti-physiological approaches of Skinner and Hull have all but disappeared from serious scientific discourse. However, the same problems such as strongly promoted self-importance of some branches of neuroscience, the lack of inter-communication between different branches and resulting lack of integrating ideas appear to emerge anew in each new generation of scientists.

    This paper is to commemorate the work of Leszek Dobaczewski who devoted much of his life to the development and application of high resolution DLTS. Under good experimental conditions Laplace DLTS provides an order of magnitude higher energy resolution than conventional DLTS techniques. This has had a profound effect on electrical defect spectroscopy enabling the effect of external probes, such as uniaxial stress, and internal perturbations, such as the proximity of atoms isovalent with the host, to be quantified in terms of electronic behaviour. Laplace DLTS provides a synergy with other techniques that was difficult or impossible to achieve previously. In this paper we present an overview of the development of LDLTS and illustrate some of its uses by describing its application in a number of key areas of defect research. Leszek Dobaczewski was born on 25th December 1954. He received his education in Warsaw taking his PhD in 1986 with Jerzy Langer at the Institute of Physics on “Recombination Processes at defects with the large lattice relaxation”. He held a research position at the institute in Warsaw until he came to Manchester in 1990 and thereafter alternated between Manchester and Warsaw. He worked primarily on the development and application of high resolution DLTS. He was awarded the degree of DSc in 1994 for his work on DX centres and held an appointment as full professor in Warsaw with Visiting Professor posts at Manchester and Aarhus. Professor Leszek Dobaczewski died in April 2010.

  3. The origin of Eastern European Jews revealed by autosomal, sex chromosomal and mtDNA polymorphisms

    PubMed Central

    2010-01-01

    Background This study aims to establish the likely origin of EEJ (Eastern European Jews) by genetic distance analysis of autosomal markers and haplogroups on the X and Y chromosomes and mtDNA. Results According to the autosomal polymorphisms the investigated Jewish populations do not share a common origin, and EEJ are closer to Italians in particular and to Europeans in general than to the other Jewish populations. The similarity of EEJ to Italians and Europeans is also supported by the X chromosomal haplogroups. In contrast according to the Y-chromosomal haplogroups EEJ are closest to the non-Jewish populations of the Eastern Mediterranean. MtDNA shows a mixed pattern, but overall EEJ are more distant from most populations and hold a marginal rather than a central position. The autosomal genetic distance matrix has a very high correlation (0.789) with geography, whereas the X-chromosomal, Y-chromosomal and mtDNA matrices have a lower correlation (0.540, 0.395 and 0.641 respectively). Conclusions The close genetic resemblance to Italians accords with the historical presumption that Ashkenazi Jews started their migrations across Europe in Italy and with historical evidence that conversion to Judaism was common in ancient Rome. The reasons for the discrepancy between the biparental markers and the uniparental markers are discussed.

    2011-01-01

    Transposable elements (TEs) were first discovered more than 50 years ago, but were totally ignored for a long time. Over the last few decades they have gradually attracted increasing interest from research scientists. Initially they were viewed as totally marginal and anecdotic, but TEs have been revealed as potentially harmful parasitic entities, ubiquitous in genomes, and finally as unavoidable actors in the diversity, structure, and evolution of the genome. Since Darwin's theory of evolution, and the progress of molecular biology, transposable elements may be the discovery that has most influenced our vision of (genome) evolution. In this review, we provide a synopsis of what is known about the complex interactions that exist between transposable elements and the host genome. Numerous examples of these interactions are provided, first from the standpoint of the genome, and then from that of the transposable elements. We also explore the evolutionary aspects of TEs in the light of post-Darwinian theories of evolution. Reviewers This article was reviewed by Jerzy Jurka, Jürgen Brosius and I. King Jordan.

    In today's world, the use of parallel programming and architectures is essential for simulating practical problems in engineering and related disciplines. Significant progress in CPU architecture (multi- and many-core CPUs, SMT, transactional memory, virtualization support, shared caches etc.) system scalability, and interconnect technology, continues to provide new opportunities, as well as new challenges for both system architects and software developers. These trends are paralleled by progress in algorithms, simulation techniques, and software integration from multiple disciplines. In its 8th year, ParSim continues to build a bridge between application disciplines and computer science and to help fostering closer cooperations between these fields. Since its successful introduction in 2002, ParSim has established itself as an integral part of the EuroPVM/MPI conference series. In contrast to traditional conferences, emphasis is put on the presentation of up-to-date results with a short turn-around time. We believe that this offers a unique opportunity to present new aspects in this dynamic field and discuss them with a wide, interdisciplinary audience. The EuroPVM/MPI conference series, as one of the prime events in parallel computation, serves as an ideal surrounding for ParSim. This combination enables participants to present and discuss their work within the scope of both the session and the host conference. This year, five papers from authors in five countries were submitted to Par-Sim, and we selected three of them. They cover a range of different application fields including mechanical engineering, material science, and structural engineering simulations. We are confident that this resulted in an attractive special session and that this will be an informal setting for lively discussions as well as for fostering new collaborations. Several people contributed to this event. Thanks go to Jack Dongarra, the EuroPVM/MPI general chair, and to Jan Westerholm, Juha

    The International Conference on 'Quantum Control, Exact or Perturbative, Linear or Nonlinear', took place in Mexico City on 22-24 October 2014. It was held with the aim of celebrating the first fifty years of scientific career of Bogdan Mielnik, an outstanding scientist whose professional trajectory spans over Poland and Mexico and who is currently Professor Emeritus in the Physics Department of Centro de Investigación y de Estudios Avanzados del IPN (Cinvestav) in Mexico. Bogdan Mielnik was born on May 6th, 1936 in Warsaw, Poland. He studied elementary and high school until 1953. In the autumn of 1953 he started the studies in the Faculty of Mathematics and Physics at the University of Warsaw, and at the end of 1957 he did his master work under the direction of Professor Jerzy Plebański. In 1962 he was invited to the newly opened Research Center of IPN (Cinvestav), in Mexico, as an assistant and PhD student of Jerzy Plebański. On October 22nd, 1964, he submitted to Cinvestav his PhD Thesis entitled ''Analytic functions of the displacement operator'', marking the offcial beginning of his scientific career. It is worth mentioning that Bogdan Mielnik is the first PhD graduate of the Physics Department of Cinvestav, so with this Conference our Department was also celebrating an important date on its calendar. A more detailed information can be found in the website http://www.fis.cinvestav.mx/mielnik50/. It was our great pleasure to see that many collaborators and former students of Bogdan Mielnik attended this Conference. The articles collected in this volume are the written contributions of the majority of talks presented at the conference.

Thanks go to Jack Dongarra, the EuroPVM/MPI general chair, and to Thomas Herault and Franck Cappello, the PC chairs, for their support to continue the ParSim series at EuroPVM/MPI 2007. We would also like to thank the numerous reviewers, who provided us with their reviews in such a short amount of time (in most cases in just a few days) and thereby helped us to maintain the tight schedule. Last, but certainly not least, we would like to thank all those who took the time to submit papers and hence made this event possible in the first place. We are confident that this session will fulfill its purpose to provide new insights from both the engineering and the computer science side and encourages interdisciplinary exchange of ideas and cooperations. We hope that this will continue ParSim's tradition at EuroPVM/MPI.

    a gene. A very important further advantage of inbreeding is that it reduces the accumulation of recessive mutations in genomes. A consequence of the model proposed is that the existence of species would correspond to a metastable equilibrium between inbreeding and outbreeding, with excessive inbreeding promoting speciation, and excessive outbreeding resulting in irreversible accumulation of recessive mutations that could ultimately only lead to extinction.

  17. CANM, a program for numerical solution of a system of nonlinear equations using the continuous analog of Newton's method

    equations are often the last step in the solution of practical problems arising in physics and engineering. The purpose of this paper is to present the iterative procedure for finding zeroes of a system of n nonlinear equations in n variables using the continuous analog of Newton's method (CANM). Method of solution: A system of n nonlinear simultaneous equations is solved by the iterative CANM procedure [2-4]. In this approach, the solution of a system F( X)= 0 is reduced to a solution of evolutionary differential equation {d}/{dt }F( X(t))=- F( X(t)), X(0)= X0, with respect to an additional continuous parameter t, 0⩽ t<∞. The resulting Cauchy problem is solved by Euler's method with variable step length τ. This iterative procedure with step τ specified in different ways [5,6], yields a variety of iterative Newton schemes that are frequently superior to the classical scheme. Restrictions on the complexity of the problem: The computer memory requirements depend on the number of nonlinear simultaneous equations to be solved. Restrictions due to dimension sizes may be easily alleviated by altering PARAMETER statements (see Long write-up and program listing for details). The user must also supply subroutine FCN which evaluates the nonlinear functions. The user has the option of either to provide a subroutine JAC which calculates the Jacobian matrix or allow the program to calculate it by the forward-difference approximation. Typical Running time: The running time depends critically upon the number of nonlinear equations to be solved. The test run which accompanies this paper took 0.06 s on the SGI Origin 2000.

    problems, there was another important theme: extending functionality. The search for greater accuracy has given an implementation of density functional designed to model van der Waals interactions accurately as well as local correlation, TDDFT and QMC and GW methods which, while not explicitly O(N), take advantage of localisation. All speakers at the workshop were invited to contribute to this issue, but not all were able to do this. Hence it is useful to give a complete list of the talks presented, with the names of the sessions; however, many talks fell within more than one area.

    and translational degrees of freedom (xii) the vitrification-related behaviour at extreme pressures in the multi-GPa domain. All these problems show that pressure studies on supercooled liquids and glassy systems can shed new light on properties observed under atmospheric pressure. In our opinion comprehensive pressure and temperature research, supported by PVT measurements and matched with sophisticated state-of-the-art modern techniques, may deliver qualitatively new input data for numerical analysis as well as for verification and construction of theoretical models. All these can form a milestone for reaching a long expected breakthrough in glass transition physics. We would like to stress the interdisciplinary significance of high pressure studies on glass forming materials. They are important not only for condensed matter and soft matter physics but also for tailoring new materials, for biotechnological issues or for deep Earth and planetary sciences 3, 9-13, 16-18. This poses an additional challenge for glassy liquids under pressure studies. This issue contains the majority of results presented at the European Science Foundation Exploratory Workshop (ESF EW) 'Glassy Liquids Under Pressure', Ustroń, Poland, 10-12 October, 2007 (convenors: Aleksandra Drozd-Rzoska (Poland) and Josep Ll Tamarit (Spain)). Aleksandra Drozd-Rzoska belongs to the group (together with Sylwester J Rzoska, Marian Paluch Paluch, Jerzy Zioło, Sebastian Pawlus, Michał Mierzwa and the staff of PhD students) from the Department of Biophysics and Molecular Physics, Institute of Physics, Silesian University, Katowice, Poland), which began pressure studies in liquids almost three decades ago. First, these investigations focused on critical mixtures and liquid crystals 21-24. On the basis of experimental solutions developed in that period, pressure studies of dielectric relaxation in supercooled, vitrifying systems began a decade ago 18, 25-27 Results associated with these studies are recalled
