    PubMed Central

    Abuelghar, Wessam Magdy; El-bishry, Gasser; Emam, Lamiaa H.

    2013-01-01

    Objective This study was designed to compare the Pfannenstiel versus Joel-Cohen incisions during caesarean deliveries. Material and Methods Women undergoing caesarean deliveries (n=153) were randomly assigned to the conventional Pfannenstiel or the Joel-Cohen incision. The outcome measures included postoperative pain, requirement for analgesics, operative time and other postoperative data. Results Maternal age, parity, gestational age and indications for caesarean delivery were similar across groups. Total operative time, postoperative recovery duration, time to get out of bed, to walk straight without support, to detect audible intestinal sounds and to pass gases or stools were shorter in the Joel-Cohen group. Postoperative haematocrit decreases and estimated intraoperative blood loss were similar between the two techniques. Moderate and severe pain at 6, 12 and 18 hours postoperatively was less frequent after the Joel-Cohen technique. Conclusion Joel-Cohen incision in the non-scarred abdomen may provide a faster technique for caesarean section with less postoperative pain and probably early postoperative recovery in our circumstances.

    Objective: Pfanennstiel incision is the most commonly used incision for cesarean section, but may not be the best. This study compared the modified Joel-Cohen incision with the Pfannenstiel incision to evaluate whether techniques to open the abdomen might influence operative time, and maternal and neonatal outcomes. Material and Methods: In a randomized comparative trial, 302 women with gestational age >34 weeks, requiring cesarean section, were randomly assigned to either modified Joel-Cohen incision or Pfannenstiel incision for entry into the peritoneal cavity. The primary outcome measure was total time required for performing operation and secondary outcome measures were baby extraction time, number of haemostatic procedures used in the abdominal wall, postoperative morbidity, postoperative hospital stay and neonatal outcome. Results: Mean total operative time was significantly less in the modified Joel-Cohen group as compared to the Pfannenstiel group (29.81 vs 32.67 min, p<0.0001, 95%CI=2.253 to 3.467). Time taken to deliver the baby and haemostatic procedures required during operation were also significantly less in the modified Joel-Cohen group as compared to the Pfannenstiel group. Requirement of strong analgesics was higher in the Pfannenstiel group (53.64% vs 21.85%, p<0.0001). There was no statically significant difference in the incidence of postoperative wound complications but postoperative stay in hospital was significantly less in the modified Joel-Cohen group (p=0.002). Neonatal outcomes were similar in both groups. Conclusion: The modified Joel-Cohen incision for entry into peritoneal cavity during cesarean section is associated with reduced mean total operative and baby extraction times with less postoperative pain and shorter hospital stay, which may be beneficial and cost effective.

  7. Amoralist rationalism? A response to Joel Marks: commentary on "Animal abolitionism meets moral abolitionism: cutting the Gordian knot of applied ethics" by Joel Marks.

    PubMed

    Lederman, Zohar

    2014-06-01

    In a recent article, Joel Marks presents the amoralist argument against vivisection, or animal laboratory experimentation. He argues that ethical theories that seek to uncover some universal morality are in fact useless and unnecessary for ethical deliberations meant to determine what constitutes an appropriate action in a specific circumstance. I agree with Marks' conclusion. I too believe that vivisection is indefensible, both from a scientific and philosophical perspective. I also believe that we should become vegan (unfortunately, like the two philosophers mentioned by Marks, I too am still struggling to reduce my meat and dairy consumption). However, I am in the dark as to Marks' vision of normative deliberations in the spirit of amoralism and desirism.

  12. Green leviathan? Thomas hobbes, joel bakan and Arnold schwarzenegger.

    PubMed

    Evans, Robert G

    2007-02-01

    Thomas Hobbes postulates that men are driven by "a perpetual and restless desire of power after power, that ceaseth only in death." The miserable consequences of this drive for power and the competing "desire of ease and sensual delight" and "fear of death and wounds" lead them to establish and obey. Substituting "profit" for "power" yields a description of the modern corporation, but without the desires or fears of natural persons. Such "unnatural persons" lack the Hobbesian ground of obligation, yet have appropriated the privileges and protections of natural persons. They challenge or undermine the sovereign wherever it limits their profits. Governor Schwarzenegger's re-election in California, however, on a strong anti-CO(2) program, suggests a willingness by threatened natural persons to re-empower Leviathan.

  17. New frontiers in fibrotic disease therapies: The focus of the Joan and Joel Rosenbloom Center for Fibrotic Diseases at Thomas Jefferson University.

    Rosenbloom, Joel; Ren, Shumei; Macarak, Edward

    2016-04-01

    Fibrotic diseases constitute a world-wide major health problem, but research support remains inadequate in comparison to the need. Although considerable understanding of the pathogenesis of fibrotic reactions has been attained, no completely effective therapies exist. Although fibrotic disorders are diverse, it is universally appreciated that a particular cell type with unique characteristics, the myofibroblast, is responsible for replacement of functioning tissue with non-functional scar tissue. Understanding the cellular and molecular mechanisms responsible for the creation of myofibroblasts and their activities is central to the development of therapies. Critical signaling cascades, initiated primarily by TGF-β, but also involving other cytokines which stimulate pro-fibrotic reactions in the myofibroblast, offer potential therapeutic targets. However, because of the multiplicity and complex interactions of these signaling pathways, it is very unlikely that any single drug will be successful in modifying a major fibrotic disease. Therefore, we have chosen to examine the effectiveness of administration of several drug combinations in a mouse pneumoconiosis model. Such treatment proved to be effective. Because fibrotic diseases that tend to be chronic, are difficult to monitor, and are patient variable, implementation of clinical trials is difficult and expensive. Therefore, we have made efforts to identify and validate non-invasive biomarkers found in urine and blood. We describe the potential utility of five such markers: (i) the EDA form of fibronectin (Fn(EDA)), (ii) lysyl oxidase (LOX), (iii) lysyl oxidase-like protein 2 (LoxL2), (iv) connective tissue growth factor (CTGF, CCNII), and (v) the N-terminal propeptide of type III procollagen (PIIINP).

    This month the focus is on branding. The Alliance Advisory Council's discussion of this topic, led by Joel English (a senior vice president with BVK/McDonald, Milwaukee, WI), identifies the key issues on branding as: 1) the debate between the local and regional nature of healthcare delivery, and the need to provide customers with the trust and security of a larger entity behind the individual provider; 2) the challenge of identifying and agreeing on a consistent message for all parts of the system; and 3) the difficulty of keeping the promise implied by a brand across these many components.

  15. X-ray FEL induced multiphton ionization and molecular dissociation

    NASA Astrophysics Data System (ADS)

    Fang, Li

    2014-05-01

    X-ray Free electron lasers (FELs) enable multiphoton absorption at the core levels which is not possible with conventional light sources. Multiphoton ionization and the subsequent core-hole states relaxation lead to dramatic dynamics of the molecules. We present our experimental as well as theoretical results on multiphoton ionization and molecular fragmentation dynamics with the Linac Coherent Light Source (LCLS) at SLAC National Laboratory. We investigated simple diatomic system, N2 molecules, where we used multiphoton ionization as an internal clock for imaging the dynamics in time and the internuclear separation domain. We observed the modification of the ionization dynamic by varying the x-ray beam parameters and the effect of the spatial distribution on the ionization. We also investigated a complex system, C60, where we developed a full model to simulate the multiphoton ionization that results in various molecular ions and atomic carbon ions up to charge 6+. The calculation agrees well with our experimental results in ion kinetic energy distribution and charge state distribution. Moreover, our model provides further insights into the photoionization and dissociation dynamics as a function of time and molecular size.

    The Sixth Annual Vaccine Renaissance Conference, hosted by the Institute for Immunology and Informatics (iCubed) at the University of Rhode Island (URI), took place on October 15-17, 2012. This conference provides a forum for the review of current progress in the discovery and development of vaccines, and creates an environment for the exchange of ideas. Dr. Joel McCleary opened the conference with a warning about the importance of preparing for well-defined biowarfare threats, including tularemia and Staphylococcal enterotoxin B. Following the keynote address, sessions explored biodefense and preparation for pandemic and biowarfare threats; vaccines for emerging and re-emerging neglected tropical diseases; animal vaccines and human health; and vaccine vectors and the human microbiome. In this issue of Human Vaccines and Immunotherapeutics, seven Vaccine Renaissance Conference speakers will showcase their work; here, we describe a few of the conference highlights.

    1973-01-01

    This chart describes the Skylab student experiment ED-61, Plant Growth, and experiment ED-62, Plant Phototropism. Two similar proposals were submitted by Joel G. Wordekemper of West Point, Nebraska, and Donald W. Schlack of Downey, California. Wordekemper's experiment (ED-61) was to see how the lack of gravity would affect the growth of roots and stems of plants. Schlack's experiment (ED-62) was to study the effect of light on a seed developing in zero gravity. The growth container of the rice seeds for their experiment consisted of eight compartments arranged in two parallel rows of four. Each had two windowed surfaces to allow periodic photography of the developing seedlings. In March 1972, NASA and the National Science Teachers Association selected 25 experiment proposals for flight on Skylab. Science advisors from the Marshall Space Flight Center aided and assisted the students in developing the proposals for flight on Skylab.

    Summary: Synthetic biology has become a widely used technology, and expanding applications in research, education and industry require progress tracking for team-based DNA synthesis projects. Although some vendors are beginning to supply multi-kilobase sequence-verified constructs, synthesis workflows starting with short oligos remain important for cost savings and pedagogical benefit. We developed BioPartsDB as an open source, extendable workflow management system for synthetic biology projects with entry points for oligos and larger DNA constructs and ending with sequence-verified clones. Availability and Implementation: BioPartsDB is released under the MIT license and available for download at https://github.com/baderzone/biopartsdb. Additional documentation and video tutorials are available at https://github.com/baderzone/biopartsdb/wiki. An Amazon Web Services image is available from the AWS Market Place (ami-a01d07c8).

  19. Regulating pharmaceutical advertising: what will work?

    PubMed

    Shapiro, M F

    1997-02-01

    As Dr. Joel Lexchin makes painfully obvious in this issue (see pages 351 to 356), regulatory processes governing pharmaceutical advertising in Canada and elsewhere are seriously compromised. However, the remedial measures Lexchin proposes are not sufficient. Financial sanctions against improper advertising are likely to be regarded by manufacturers as the cost of doing business, and any regulatory body that includes drug industry representatives or individuals receiving financial support from the drug industry cannot be genuinely independent. Moreover, manufacturers are now using promotional strategies that are particularly difficult to regulate. These include providing drugs at lower than the usual cost to ensure their inclusion in managed-care formularies, and using direct-to-consumer advertising to take advantage of the public's lack of sophistication in interpreting scientific evidence. Our best hope of counteracting the power and influence of the drug industry lies in regulation by government agencies, whose interest is the protection of the public.

    In 1951, the four pages of the US Constitution, the Letter of Transmittal, the Bill of Rights and the Declaration of Independence, collectively called the 'Charters of Freedom,' were hermetically sealed individually in glass encasements. The atmosphere in the encasements consisted of a mixture of helium with water vapor at a relative humidity between 25 and 35% at room temperature. In 1998, Margaret Kelly of the National Archives and Records Administration (NARA), contacted Dr. Joel S. Levine at NASA Langley Research Center (LaRC) to request assistance in determining the chemical composition of the atmosphere inside the encasements. Several different Langley learns were assembled to address that request. each using a different measurement technique. This report describes the method and results of one team's relative humidity measurements on encasements containing pages 1 and 4 of the US Constitution, the Bill of Rights, and the Declaration of Independence performed at NARA, College Park.

    The choice of the type of abdominal incision performed in caesarean delivery is made chiefly on the basis of the individual surgeon’s experience and preference. A general consensus on the most appropriate surgical technique has not yet been reached. The aim of this systematic review of the literature is to compare the two most commonly used transverse abdominal incisions for caesarean delivery, the Pfannenstiel incision and the modified Joel-Cohen incision, in terms of acute and chronic post-surgical pain and their subsequent influence in terms of quality of life. Electronic database searches formed the basis of the literature search and the following databases were searched in the time frame between January 1997 and December 2013: MEDLINE, EMBASE Sciencedirect and the Cochrane Library. Key search terms included: “acute pain”, “chronic pain”, “Pfannenstiel incision”, “Misgav-Ladach”, “Joel Cohen incision”, in combination with “Caesarean Section”, “abdominal incision”, “numbness”, “neuropathic pain” and “nerve entrapment”. Data on 4771 patients who underwent caesarean section (CS) was collected with regards to the relation between surgical techniques and postoperative outcomes defined as acute or chronic pain and future pregnancy desire. The Misgav-Ladach incision was associated with a significant advantage in terms of reduction of post-surgical acute and chronic pain. It was indicated as the optimal technique in view of its characteristic of reducing lower pelvic discomfort and pain, thus improving quality of life and future fertility desire. Further studies which are not subject to important bias like pre-existing chronic pain, non-standardized analgesia administration, variable length of skin incision and previous abdominal surgery are required.

    A collaborative approach to communicating our amazing science. RAL Space at the Rutherford Appleton Lab, has initiated a unique collaboration with a team of award-winning performing artists with the aim of making space science research engaging and accessible to a wide audience. The collaboration has two distinct but connected strands one of which is the development of a contemporary dance work inspired by solar science and including images and data from the Space Physics Division of STFC RAL Space. The work has been commissioned by Sadler's Wells, one of the world's leading dance venues. It will be created by choreographer Alexander Whitley, video artist Tal Rosner and composers Ella Spira and Joel Cadbury and toured throughout the UK and internationally by the Alexander Whitley Dance Company (AWDC). The work will come about through collaboration with the work of the scientists of RAL Space and in particular the SOHO, CDS and STEREO missions, taking a particular interest in space weather. Choreographer Alexander Whitley and composers Ella Spira and Joel Cadbury will take their inspiration from the images and data that are produced by the solar science within RAL Space. Video artist Tal Rosner will use these spectacular images to create an atmospheric backdrop to accompany the work, bringing the beauty and wonder of space exploration to new audiences. Funding for the creation and touring of the work will be sought from Arts Council England, the British Council, partner organisations, trusts and foundations and private donors.The world premiere of the work will take place at Sadler's Wells in June 2017. It will then tour throughout the UK and internationally to theatres, science conferences and outreach venues with the aim of bringing the work of STFC RAL Space and the science behind solar science and space weather to new audiences. An education programme will combine concepts of choreography and space science aimed at young people in year 5 Key Stage 2 and be

    1995-01-26

    PREFACE The Twentieth Workshop on Geothermal Reservoir Engineering, dedicated to the memory of Professor Hank Ramey, was held at Stanford University on January 24-26, 1995. There were ninety-five registered participants. Participants came from six foreign countries: Japan, Mexico, England, Italy, New Zealand and Iceland. The performance of many geothermal reservoirs outside the United States was described in several of the papers. Professor Roland N. Horne opened the meeting and welcomed visitors to the campus. The key note speaker was Marshall Reed, who gave a brief overview of the Department of Energy's current plan. Thirty-two papers were presented in the technical sessions of the workshop. Technical papers were organized into eleven sessions concerning: field development, modeling, well tesubore, injection, geoscience, geochemistry and field operations. Session chairmen were major contributors to the workshop, and we thank: Ben Barker, Bob Fournier, Mark Walters, John Counsil, Marcelo Lippmann, Keshav Goyal, Joel Renner and Mike Shook. In addition to the technical sessions, a panel discussion was held on ''What have we learned in 20 years?'' Panel speakers included Patrick Muffler, George Frye, Alfred Truesdell and John Pritchett. The subject was further discussed by Subir Sanyal, who gave the post-dinner speech at the banquet. The Workshop was organized by the Stanford Geothermal Program faculty, staff, and graduate students.

    Dating the crucifixion on friday 3 April 33, when, at sunset a partially eclipsed Moon rised allows to interprete the speech of Saint Peter (Acts 2:20=Joel 3:4) on the day of Pentecost as including an account of this eclipse, as fulfillment of the Scriptures. Few minutes later the apparition of a third star of medium magnitude stated the beginning of the sabbatical rest: before that time Jesus has been buried, wrapped into the shroud. The observations of the equinoctial moonrise from the Mount of Olives on September 2013 are strongly in favour of the hypotehsis of possible observation of the lunar eclipse of 33 AD by Jewish people, as well as the sunrises observed from the Temple Institute terrace in Southern-East Jerusalem demonstrated that this eclipse could have been seen from Jerusalem. The depression of the horizon and the refraction allow to see Sun and Moon more than 1 degree below the geometrical horizon in the azimuthal direction ranging from 90 to 116, prologing to 16 minutes the duration of the partial lunar eclipse observed in 33AD. Texts of Matthew, Mark and Cyrillus of Jerusalem are also commented.

    Summary: Combinatorial assembly of DNA elements is an efficient method for building large-scale synthetic pathways from standardized, reusable components. These methods are particularly useful because they enable assembly of multiple DNA fragments in one reaction, at the cost of requiring that each fragment satisfies design constraints. We developed BioPartsBuilder as a biologist-friendly web tool to design biological parts that are compatible with DNA combinatorial assembly methods, such as Golden Gate and related methods. It retrieves biological sequences, enforces compliance with assembly design standards and provides a fabrication plan for each fragment. Availability and implementation: BioPartsBuilder is accessible at http://public.biopartsbuilder.org and an Amazon Web Services image is available from the AWS Market Place (AMI ID: ami-508acf38).

  10. The child's right to an open future: is the principle applicable to non-therapeutic circumcision?

    PubMed

    Darby, Robert J L

    2013-07-01

    The principle of the child's right to an open future was first proposed by the legal philosopher Joel Feinberg and developed further by bioethicist Dena Davis. The principle holds that children possess a unique class of rights called rights in trust-rights that they cannot yet exercise, but which they will be able to exercise when they reach maturity. Parents should not, therefore, take actions that permanently foreclose on or pre-empt the future options of their children, but leave them the greatest possible scope for exercising personal life choices in adulthood. Davis particularly applies the principle to genetic counselling, arguing that parents should not take deliberate steps to create physically abnormal children, and to religion, arguing that while parents are entitled to bring their children up in accordance with their own values, they are not entitled to inflict physical or mental harm, neither by omission nor commission. In this paper, I aim to elucidate the open future principle, and consider whether it is applicable to non-therapeutic circumcision of boys, whether performed for cultural/religious or for prophylactic/health reasons. I argue that the principle is highly applicable to non-therapeutic circumcision, and conclude that non-therapeutic circumcision would be a violation of the child's right to an open future, and thus objectionable from both an ethical and a human rights perspective.

  11. MinActionPath: maximum likelihood trajectory for large-scale structural transitions in a coarse-grained locally harmonic energy landscape.

    The non-linear problem of simulating the structural transition between two known forms of a macromolecule still remains a challenge in structural biology. The problem is usually addressed in an approximate way using 'morphing' techniques, which are linear interpolations of either the Cartesian or the internal coordinates between the initial and end states, followed by energy minimization. Here we describe a web tool that implements a new method to calculate the most probable trajectory that is exact for harmonic potentials; as an illustration of the method, the classical Calpha-based Elastic Network Model (ENM) is used both for the initial and the final states but other variants of the ENM are also possible. The Langevin equation under this potential is solved analytically using the Onsager and Machlup action minimization formalism on each side of the transition, thus replacing the original non-linear problem by a pair of linear differential equations joined by a non-linear boundary matching condition. The crossover between the two multidimensional energy curves around each state is found numerically using an iterative approach, producing the most probable trajectory and fully characterizing the transition state and its energy. Jobs calculating such trajectories can be submitted on-line at: http://lorentz.dynstr.pasteur.fr/joel/index.php.

    MAUNA KEA, HAWAII Astronomers: Imke de Pater, James R. Graham, Garrett Jernigan University of California, Berkeley with support from Wendy Harrison, Joel Aycock, David Vezie and the staff of the Keck Observatory The movie shows the impact of Fragment-R of Comet Shoemaker-Levy 9 with Jupiter. The impact was observed at near-infrared wavelengths, 2.3 microns. In the beginning of the movie, only part of the Southern hemisphere is visible with two former impact sites. The former impact site of Fragments P and Q appears on the left side. R hits this same spot. The movie covers a timespan of approximately half an hour. At 5:33 UT a first flash is detected just above the impact site, lasting for approximately 20 seconds. A second flash is detected about 20 seconds later, lasting for about a minute. Several minutes later the fireball becomes visible as a bright spot, increasing rapidly in intensity. Within a few minutes it is outshining the entire planet. The rise and fall in intensity takes about 8 minutes.

    Biodiversity conservation has been criticized for undermining or ignoring social well-being. Currently efforts to mutually promote social justice, rural development, and biodiversity conservation, which have been contentious and yielded mixed results, continue to spread despite a general dearth of effective management strategies. We contend that social and economic concerns should be integral to conservation planning and propose that the scale of these phenomena is also critical. To evaluate the merit of this proposal, we adopted and expanded a conservation management strategy framework developed by Joel Heinen and examined how population density, economic disparity, and ethnic heterogeneity vary spatially surrounding 2 contrasting protected areas in East Africa: Kibale National Park in Uganda and Tarangire National Park in Tanzania. Analyses of demographic, wealth, and ethnicity data from regional censuses and household surveys conducted in 2009 and 2010 indicated that choice of scale (landscape or community) changed the management strategies recommended by the model. Therefore, "several small" people-park management strategies varying around a given protected area may be more appropriate than a "single large" people-park strategy applied across an entire protected area. Correspondingly, scale adjusted Heinen recommendations offered new strategies for effective conservation management within these human landscapes not incorporated in current in situ management plans.

    This article summarizes the proceedings of a symposium presented at the 2004 meeting of the Research Society on Alcoholism (RSA) in Vancouver, British Columbia, Canada. There were four presentations and a discussant. The symposium was co-chaired by Tina Zawacki and Jeanette Norris. The first presentation was made by Jeanette Norris, who found that alcohol consumption and preexisting alcohol expectancies affected women's hypothetical responses to a vignette depicting acquaintance sexual aggression. The second presentation was made by Joel Martell, who reported that alcohol-induced impairment of executive cognitive functioning mediated the effect of intoxication on men's perceptions of a sexual assault vignette. In the third presentation, Antonia Abbey found that the experiences of women whose sexual assault involved intoxication or force were more negative than were the experiences of women whose sexual assault involved verbal coercion. The fourth presentation was made by Tina Zawacki, who reported that men who perpetrated sexual assault only in adolescence differed from men who continued perpetration into adulthood in terms of their drinking patterns and attitudes toward women. William H. George discussed these findings in terms of their implications for theory development and prevention programming.

    The purpose of the study is to evaluate the effect of various laser techniques for bleaching teeth in office vital whitening. Hydrogen peroxide (30% concentration) and carbamide peroxide (10% solution) were used for chemical activation of bleaching process. Extracted non-carcious upper central incisors were exposed to laser radiation. Four different laser systems (Nd:YAG laser SHG, wavelength 0.53 μm, CTE:YAG laser, wavelength 2.7 μm, Nd:YAG laser, wavelength 1.06 μm, and alexandrite laser, wavelength 0.75 μm) were applied to accelerate the speed of the process. The end of chemical exposition was verified by the change of bleaching agent color. The color change was determined by stereomicroscope (Nikon SMZ 2T, Japan), the quality of surface structure was checked by scanning electron microscope Joel, Japan). The speed of bleaching rnaged from 630 s (chemical methods only) to 250-340 s (chemicals + alexandrite laser radiation). The Alexandrite laser application was considered an elective process to decrease the time of bleaching without modifying the surface.

    The automation of various parts of multiple--cycle direct oxide reduction (MCDOR) at LANL`s NMT-3 was the goal of this research and development activities. In particular, originally the following goals were assigned to the author by the NMT-3 technical staff leaders (Greg Bird, Jim McNeese, Joel Williams): (1) Design and fabricate an automation set up; (2) Step-wise automation is preferred; (3) Step 1 involves automatic metering and mixing of powders; and (4) Step 2-automatic transport of powder to furnace location The initial task assigned in May 91 was to get the appropriate design developed and order equipment and parts to automatically weight powders. In fact the work statement read {open_quotes}Create an experimental automation set up in the ME Department at UNM to automatically weigh powders using an electronic balance. Further, design the set up such that the electronic balance is reprogrammable for specific weight set points. Thus, when a set point in weight is reached by means of a vibratory feeder feeding a container on the balance, the electronic balance will send an electronic signal out to switch off the vibratory feeder{close_quotes}. The automation of the reduction of plutonium oxide to plutonium is described.

    2004-12-01

    Between 1930 and 1958, the Washburn Observatory of the University of Wisconsin-Madison was home to pioneering photometric research into the interstellar medium by Joel Stebbins and Albert Whitford. Between 1933 and 1941, Stebbins and Whitford published seminal research on the photometry of stellar reddening, using the Washburn 15-inch refractor and the 60- and 100-inch reflectors at Mount Wilson Observatory. Many factors were responsible for the Washburn Observatory's pre-eminence in this area. This paper reviews their research on interstellar dust during the years 1922-58, the observational technology and scientific methods that were developed at the Washburn Observatory during that time and the scientific discoveries that originated there. We discuss the factors that enabled Washburn Observatory to become a leader in photometry during the first half of the twentieth century. We also draw on the recollections of past and present Washburn Observatory scientists to understand how Washburn's standing led to a subsequent programme of research into the interstellar medium at the University of Wisconsin-Madison. The resulting portrayal of Washburn Observatory provides insights into the evolution of astronomical research in America, from the beginning of the twentieth century until today.

    2011-01-01

    Background The availability of large-scale high-throughput data possesses considerable challenges toward their functional analysis. For this reason gene network inference methods gained considerable interest. However, our current knowledge, especially about the influence of the structure of a gene network on its inference, is limited. Results In this paper we present a comprehensive investigation of the structural influence of gene networks on the inferential characteristics of C3NET - a recently introduced gene network inference algorithm. We employ local as well as global performance metrics in combination with an ensemble approach. The results from our numerical study for various biological and synthetic network structures and simulation conditions, also comparing C3NET with other inference algorithms, lead a multitude of theoretical and practical insights into the working behavior of C3NET. In addition, in order to facilitate the practical usage of C3NET we provide an user-friendly R package, called c3net, and describe its functionality. It is available from https://r-forge.r-project.org/projects/c3net and from the CRAN package repository. Conclusions The availability of gene network inference algorithms with known inferential properties opens a new era of large-scale screening experiments that could be equally beneficial for basic biological and biomedical research with auspicious prospects. The availability of our easy to use software package c3net may contribute to the popularization of such methods. Reviewers This article was reviewed by Lev Klebanov, Joel Bader and Yuriy Gusev.

    Cosmology is in the midst of a scientific revolution that is establishing its lasting foundations. The good agreement between many different sorts of observations and the predictions of the now-standard Lambda Cold Dark Matter (LCDM) theory gives us hope that this is humanity's first picture of the history of the universe as a whole that might actually be true. An unexpected feature of this new picture is that we humans appear to be central or special in many ways -- for example, we are made of the rarest stuff in the universe (stardust); we are intermediate in size between the smallest possible size (the Planck length) and the largest size (the cosmic horizon); and we are living at a pivotal time: the period in the history of the universe when its expansion began to accelerate rather than slow down, and in the middle of the ten-billion-year lifetime of our solar system and of the billion year most habitable period of our planet, and at what must be the end of the exponential growth of human impact on the earth. This talk will review key observations that support modern cosmology, describe some symbolic ways of understanding the modern cosmos, and discuss some possible implications of a cosmic perspective for our 21st century worldview. Based on a new book, The View from the Center of the Universe: Discovering Our Extraordinary Place in the Cosmos, by Joel R. Primack and Nancy Ellen Abrams (Riverhead Books, April 2006).

    Joel Cohen proposed that "mathematics is biology's next microscope, only better; biology is mathematics' next physics, only better." Here, we aim for something even better. We try to combine mathematical physics and biology into a picoscope of life. For this, we merge techniques that were introduced and developed in modern mathematical physics, largely by Ludvig Faddeev, to describe objects such as solitons and Higgs and to explain phenomena such as anomalies in gauge fields. We propose a synthesis that can help to resolve the protein folding problem, one of the most important conundrums in all of science. We apply the concept of gauge invariance to scrutinize the extrinsic geometry of strings in three-dimensional space. We evoke general principles of symmetry in combination with Wilsonian universality and derive an essentially unique Landau-Ginzburg energy that describes the dynamics of a generic stringlike configuration in the far infrared. We observe that the energy supports topological solitons that relate to an anomaly similarly to how a string is framed around its inflection points. We explain how the solitons operate as modular building blocks from which folded proteins are composed. We describe crystallographic protein structures by multisolitons with experimental precision and investigate the nonequilibrium dynamics of proteins under temperature variations. We simulate the folding process of a protein at in vivo speed and with close to picoscale accuracy using a standard laptop computer. With picobiology as next pursuit of mathematical physics, things can only get better.

    1997-12-01

    The tenth meeting of the Astronomical and Astrophysical Society of America (later to become the AAS), held in August 1909, was also its tenth-anniversary (or decennial) meeting. Fifty-three members were present, as contrasted with the 1400 expected for the 194th, Centennial meeting to be held in Chicago in May-June 1999, and forty-one papers were presented, rather than the 1000 predicted for next year. Other similarities and differences between meetings then and now will be described and illustrated. Simon Newcomb, the first AAS President, had died in July 1909, and Edward C. Pickering, who had succeeded him in 1905 and was to remain President until 1919, eulogized him at the Yerkes meeting. Two Committees, on Luminous Meteors and on Comets, respectively, presented their reports, the latter's dealing mostly with plans for Comet Halley at its 1910 apparition. A high-level Special Committee issued a statement decrying a newspaper furor over establishing communication with Mars, which they said was then ``outside the range of contemporary science." Six of the members present at the 1909 meeting were women. Joel Stebbins, later to be Councilor, Secretary, Vice President and President, presented his first AAS paper, on his new selenium (photo-resistive) photometry. Frank Schlesinger, another future Society President, was also present and read an instrument-design paper. Ten of the papers were given by Yerkes and University of Chicago astronomers, including three by E. E. Barnard and two by Kurt Laves. Another six papers from distant Lick Observatory members were read in absentia. S. W. Burnham, who was at the Yerkes meeting, was the one famous astronomer who never joined the Society. Finally, the Council authorized publication of a Decennial Book, to provide a record of the first ten years of the young Society.

    1996-05-01

    George C. Comstock, the third director of Washburn Observatory, had a long and interesting career at Wisconsin. Born in Madison, he did his undergraduate work at Michigan under James Watson. From him Comstock learned the classical astronomy of stellar positions and celestial mechanics. He had one year of graduate work at Michigan before going to Madison as Watson's assistant in 1880, and remained after the latter's death as E.S. Holden's assistant. At Wisconsin, Comstock also studied law at the UW Law School in his ``spare time", to have an alternate career path. He was admitted to the bar in 1883 but never practiced. From 1885-7 he was on the Ohio State faculty with a summer working at Lick Observatory; then in 1887 became associate director back at Washburn Observatory. Two years later he succeeded to the full directorship, and kept the post until he retired in 1922 at the age of 67. All Comstock's research was in positional astronomy, and he considered his most important work to be the measurement of stellar aberration and atmospheric refraction. He also measured double stars with the 15-inch Washburn refractor. His main duty at UW was teaching, mostly ``practical astronomy" for civil engineering students. Comstock wrote several text books on astronomy, surveying, and least squares. He was the first head of the UW Graduate School, set up by President Charles R. Van Hise in 1904. Comstock was a highly effective administrator, and did much to build up research at UW. His own most successful students were Sidney D. Townley, Joel Stebbins, and Sebastian Albrecht. Because of his legal training, Comstock was involved as an officer in many scientific societies. He was one of the organizers of the AAS, its first secretary, and later its vice president, then president. He retired in 1922, and was succeeded by Stebbins, whom he helped to bring back to Madison from Illinois. After his retirement, Comstock lived in Beloit until his death in 1934.

    Motivation: Underrepresentation of racial groups represents an important challenge and major gap in phenomics research. Most of the current human phenomics research is based primarily on European populations; hence it is an important challenge to expand it to consider other population groups. One approach is to utilize data from EMR databases that contain patient data from diverse demographics and ancestries. The implications of this racial underrepresentation of data can be profound regarding effects on the healthcare delivery and actionability. To the best of our knowledge, our work is the first attempt to perform comparative, population-scale analyses of disease networks across three different populations, namely Caucasian (EA), African American (AA) and Hispanic/Latino (HL). Results: We compared susceptibility profiles and temporal connectivity patterns for 1988 diseases and 37 282 disease pairs represented in a clinical population of 1 025 573 patients. Accordingly, we revealed appreciable differences in disease susceptibility, temporal patterns, network structure and underlying disease connections between EA, AA and HL populations. We found 2158 significantly comorbid diseases for the EA cohort, 3265 for AA and 672 for HL. We further outlined key disease pair associations unique to each population as well as categorical enrichments of these pairs. Finally, we identified 51 key ‘hub’ diseases that are the focal points in the race-centric networks and of particular clinical importance. Incorporating race-specific disease comorbidity patterns will produce a more accurate and complete picture of the disease landscape overall and could support more precise understanding of disease relationships and patient management towards improved clinical outcomes.

    The institution which succeeded the Mt. Wilson Station of Yerkes Observatory in 1904 has had six names and three sites. From 1948-1980 it was united with Caltech's Palomar Observatory, and since then its main observatory has been in Chile, though still headquartered on Santa Barbara Street in Pasadena. For more than half of the twentieth century it was the leading observatory in the world. One bit of evidence for this is the amazing number of its staff members awarded the Bruce Medal. The Catherine Wolfe Bruce Gold Medal of the Astronomical Society of the Pacific has been awarded for lifetime contributions to astronomy since 1898. It is an international award. It wasn't until 1963 that the number of medalists who had worked primarily in the United States reached half the total. Yet fourteen of the first 87 medalists spent most of their careers at Mt. Wilson, including the period when it was Mt. Wilson and Palomar, and another three were Caltech observers who used the telescopes of the jointly operated observatory. Several more medalists made substantial use of the telescopes on Mt. Wilson and Palomar Mountain. We will discuss highlights of the careers of a number of these distinguished astronomers: directors George Ellery Hale, Walter Adams, Ira Bowen, and Horace Babcock; solar observer and satellite discoverer Seth Nicholson; instrument builder Harold Babcock; galactic and cosmological observers Frederick Seares, Edwin Hubble, Walter Baade, Rudolph Minkowski, and Allan Sandage; and spectroscopists Paul Merrill, Alfred Joy, Olin Wilson, Jesse Greenstein, Maarten Schmidt, and Wallace Sargent. We will touch briefly on others who used Mt. Wilson and/or Palomar, including Harlow Shapley, Joel Stebbins, Charlotte Moore Sitterly, Donald Osterbrock, and Albert Whitford.

    Fibrinogen `Cedar Rapids` is a heterozygous dysfibrinogenemia characterized by delayed and abnormal fibrin polymerization. The specific molecular defect ({gamma}R275C) is relatively common, but in only one case, fibrinogen Tokyo II, has the ultrastructural basis for defective clot formation been determined. This report reflects similar structural studies on Cedar Rapids fibrinogen and fibrin. Crosslinked fibrinogen molecules and fibrils, were prepared at 1 mg/ml in the presence of factor XIIIa (100 u/ml). When {gamma} chains had become {approximately}10 to 20% crosslinked to {gamma} dimers, samples were diluted with Hepes buffered saline, pH 7, to a fibrinogen concentrated of 5 to 10 {mu}g/ml. Three {mu}l was then injected into 3 {mu}l buffer on a carbon-coated EM grid, the specimen allowed to attach for one minute, fluid-exchanged several times with 150 mM NH{sub 4} acetate solution, frozen in liquid nitrogen, freeze-dried, and imaged at the Brookhaven STEM facility using a 40 kv probe focused at 0.25 nm. Fibrin for scanning EM (SEM) was formed directly on carbon-formvar coated gold grids. Clots that had formed overnight were fixed with 2.5% glutaraldehyde in 0.1 M Hepes, pH 7 buffer containing 0.2% tannic acid, washed with buffer, dehydrated, CO{sub 2} critical point dried, coated with 7.5 nm platinum, and imaged in a JOEL Field Emission SEM operated at 5 kV.

    To prepare for the exploration of Mars by humans, as outlined in the new national vision for Space Exploration (VSE), the Mars Exploration Program Analysis Group (MEPAG), chartered by NASA's Mars Exploration Program (MEP), formed a Human Exploration of Mars Science Analysis Group (HEM-SAG), in March 2007. HEM-SAG was chartered to develop the scientific goals and objectives for the human exploration of Mars based on the Mars Scientific Goals, Objectives, Investigations, and Priorities.1 The HEM-SAG is one of several humans to Mars scientific, engineering and mission architecture studies chartered in 2007 to support NASA s plans for the human exploration of Mars. The HEM-SAG is composed of about 30 Mars scientists representing the disciplines of Mars biology, climate/atmosphere, geology and geophysics from the U.S., Canada, England, France, Italy and Spain. MEPAG selected Drs. James B. Garvin (NASA Goddard Space Flight Center) and Joel S. Levine (NASA Langley Research Center) to serve as HEMSAG co-chairs. The HEM-SAG team conducted 20 telecons and convened three face-to-face meetings from March through October 2007. The management of MEP and MEPAG were briefed on the HEM-SAG interim findings in May. The HEM-SAG final report was presented on-line to the full MEPAG membership and was presented at the MEPAG meeting on February 20-21, 2008. This presentation will outline the HEM-SAG biology and climate/atmosphere goals and objectives. A companion paper will outline the HEM-SAG geology and geophysics goals and objectives.

  12. Partial Reform Equilibrium in Russia: A Case Study of the Political Interests of and in the Russian Gas and Oil Industry

    NASA Astrophysics Data System (ADS)

    Everett, Rabekah

    While several theories abound that attempt to explain the obstacles to democracy in Russia, Joel Hellman's partial reform equilibrium model is an institutional theory that illustrates how weak institutions, combined with an instrumentalist cultural approach to the law and authoritarian-minded leadership, allowed the struggle over interests to craft and determine the nature of Russia's political structure. This thesis builds on the work of Hellman by using the partial reform theory to understand the evolution of interest infiltration and their impact on the formation of policies and institutions in favour of the elites or winners from 2004 to the present time period that allow them to wield law as a political weapon. The hypothesis posits that through their vested interests in state politics, the political and economic elites of the oil and gas industry have successfully stalled reform in Russia resulting in partial reform equilibrium. This is illustrated in a case study that was designed to collect the names, backgrounds, and social networks of gas and oil executives in order to determine how many of them have a history of, or are currently working as, ministers in the government or representatives in the Federation Council. The objective being to measure the degree to which gas and oil interests are present in government decision-making and conversely, the degree to which the government is present in the gas and oil industry. The thesis stresses the importance of institutional structure in determining Russia's political evolution, and uses vested interests as a primary source of structural institutional change, while also stressing on the social and international implications of this evolution.

  13. Vigor in the face of fluctuating rates of reward: an experimental examination.

    Two fundamental questions underlie the expression of behavior, namely what to do and how vigorously to do it. The former is the topic of an overwhelming wealth of theoretical and empirical work particularly in the fields of reinforcement learning and decision-making, with various forms of affective prediction error playing key roles. Although vigor concerns motivation, and so is the subject of many empirical studies in diverse fields, it has suffered a dearth of computational models. Recently, Niv et al. [Niv, Y., Daw, N. D., Joel, D., & Dayan, P. Tonic dopamine: Opportunity costs and the control of response vigor. Psychopharmacology (Berlin), 191, 507-520, 2007] suggested that vigor should be controlled by the opportunity cost of time, which is itself determined by the average rate of reward. This coupling of reward rate and vigor can be shown to be optimal under the theory of average return reinforcement learning for a particular class of tasks but may also be a more general, perhaps hard-wired, characteristic of the architecture of control. We, therefore, tested the hypothesis that healthy human participants would adjust their RTs on the basis of the average rate of reward. We measured RTs in an odd-ball discrimination task for rewards whose magnitudes varied slowly but systematically. Linear regression on the subjects' individual RTs using the time varying average rate of reward as the regressor of interest, and including nuisance regressors such as the immediate reward in a round and in the preceding round, showed that a significant fraction of the variance in subjects' RTs could indeed be explained by the rate of experienced reward. This validates one of the key proposals associated with the model, illuminating an apparently mandatory form of coupling that may involve tonic levels of dopamine.

    This project funded the participation of scientists from seven research groups, running more than thirty instruments, in the Winter Intensive Operating Period (January-February 2012) of the Clean Air for London (ClearfLo) campaign at a rural site in Detling, UK, 45 km southeast of central London. The primary science questions for the ClearfLo Winter IOP were, 1) what is the urban increment of particulate matter (PM) and other pollutants in the greater London area, and, 2) what is the contribution of solid fuel use for home heating to wintertime PM? An additional motivation for the Detling measurements was the question of whether coatings on black carbon particles enhance absorption. The following four key accomplishments have been identified so far: 1) Chemical, physical and optical characterization of PM from local and regional sources (Figures 2, 4, 5 and 6). 2) Measurement of urban increment in particulate matter and gases in London (Figure 3). 3) Measurement of optical properties and chemical composition of coatings on black carbon containing particles indicates absorption enhancement. 4) First deployment of chemical ionization instrument (MOVI-CI-TOFMS) to measure both particle-phase and gas-phase organic acids. (See final report from Joel Thornton, University of Washington, for details.) Analysis of the large dataset acquired in Detling is ongoing and will yield further key accomplishments. These measurements of urban and rural aerosol properties will contribute to improved modeling of regional aerosol emissions, and of atmospheric aging and removal. The measurement of absorption enhancement by coatings on black carbon will contribute to improved modeling of the direct radiative properties of PM.

    The National Institute on Alcohol Abuse and Alcoholism (NIAAA) sponsored a May 2002 workshop on gene-environment interaction (G x E) research to identify potential roadblocks to further research and to propose solutions to those roadblocks, to optimize investigative opportunities and multidisciplinary or multi-institution collaborations, and to explore ways that NIAAA can facilitate G x E studies. Sessions included panels on animal models; phenotypes; genetic findings in humans; study designs and analytical methods; and assessment of environmental risk. Key among the identified challenges to progress in G x E research were issues of study design and sampling strategies; logistic and methodological costs and constraints; availability and understanding of data analysis techniques; potential stigmatization of study populations; and organizational/bureaucratic structures that are inadequate to address the unique needs of large-scale, multicenter, longitudinal projects. Participants proposed a series of recommendations to address these issues. Session coordinators included: Gayle Boyd, Kendall Bryant, Page Chiapella, Vivian Faden, David Goldman, and Antonio Noronha. Session participants included: Laura Almasy, Henri Begleiter, Raul Caetano, Bruce Dudek, Mary Dufour, Cindy Ehlers, Mary-Anne Enoch, Joel Gelernter, David Goldman, Bridget Grant, Lorraine Gunzerath, Deborah Hasin, Andrew Heath, Victor Hesselbrock, J.

    The AAS celebrated its "semi-centennial" fifty-two years ago! It was actually the fiftieth anniversary of the "First Conference" of astronomers and astrophysicists held at the dedication of Yerkes Observatory in 1897, which led to the actual formation of the Society two years later. Otto Struve, president of the AAS, was publicizing the fiftieth anniversary of his Yerkes Observatory in 1947, and he simply announced it was also the semi-centennial of the Society. Joel Stebbins, the grand old man of the AAS who had joined it as a graduate student in 1900, and held nearly every office in the Society from councilor to president, supported Struve's early celebration of the anniversary, probably largely because he was to retire himself in 1948. The meeting was held at Northwestern University and at Yerkes. There were then 625 AAS members. About 140 of them attended the meeting, and presented some 50 papers, all oral, with no parallel sessions. Struve organized a symposium on stellar atmospheres, with 5 invited speakers, and the great majority of the contributed papers were also on stars, a few on nebulae and interstellar matter, one on galaxies, and none on cosmology. Not to be outdone, Gerard P. Kuiper, who had recently succeeded Struve as director of Yerkes Observatory, organized a second symposium on the atmospheres of the planets, held at Yerkes immediately after the AAS meeting. After two days of sessions at Evanston, the members had driven to Williams Bay for the closing session Saturday, at which Struve and Stebbins gave their versions of the history of the observatory and of the Society. The two symposia formed the bases for two important books, Astrophysics: A Topical Symposium, and The Atmospheres of the Earth and the Planets, edited by J. Allen Hynek and Kuiper respectively.

    Here we present the results of the 6th biennial optical interferometry imaging beauty contest. Taking advantage of a unique opportunity, the red supergiant VY CMa and the Mira variable R Car were observed in the astronomical H-band with three 4-telescope configurations of the VLTI-AT array using the PIONIER instrument. The community was invited to participate in the subsequent image reconstruction and interpretation phases of the project. Ten groups submitted entries to the beauty contest, and we found reasonable consistency between images obtained from independent workers using quite different algorithms. We also found that significant differences existed between the submitted images, much greater than in past beauty contests that were all based on simulated data. A novel crowd-sourcing" method allowed consensus median images to be constructed, filtering likely artifacts and retaining real features." We definitively detect strong spots on the surfaces of both stars as well as distinct circumstellar shells of emission (likely water/CO) around R Car. In a close contest, Joel Sanchez (IAA-CSIC/Spain) was named the winner of the 2014 interferometric imaging beauty contest. This process has shown that new comers" can use publicly-available imaging software to interpret VLTI/PIONIER imaging data, as long as sufficient observations are taken to have complete uv coverage { a luxury that is often missing. We urge proposers to request adequate observing nights to collect sufficient data for imaging and for time allocation committees to recognise the importance of uv coverage for reliable interpretation of interferometric data. We believe that the result of the proposed broad international project will contribute to inspiring trust in the image reconstruction processes in optical interferometry.

    We report data on three new irons from Northern Chile, and propose names. All are unnamed irons from the meteorite collection at the Universidad de La Serena. For two the provenance is unknown, for the third the presumed discovery site is in the countryside east of Iquique. The three have been analyzed by neutron-activation analysis and their structures examined with a binocular microscope. La Serena is a complete 663 g iron, a new member of group IIICD; it is not paired with any other iron. Elqui has a mass of 260 g; two faces are fractures, possibly produced by human actions, but fusion crust appears to be present on some of the remaining surface. It is a hexahedrite and a member of group IIAB. but its composition differs from that of all other Chilean hexahedrites. The third iron, Pozo Almonte, is a medium octahedrite member of group IIIAB, one of the most common meteorite groups. To find out whether it is paired, we assembled a full set of IIIAB irons from Northern Chile. Our compositional data show that Pozo Almonte is not paired with any other IIIAB iron, and that there are no pairings within the full set with the possible exception of Joel's Iron and Sierra Sandon, which differ only in their contents of Ir, 0.39 and 0.34 mg/g, respectively. However, Buchwald's (1975) structural observations rule out this possible pairing. We find appreciable differences in Cu, As and Au between the previously paired IIIAB irons Chanaral and Ilimaes, and conclude that these should not be paired.

    Reviews the books, Cold War Social Science: Knowledge Production, Liberal Democracy, and Human Nature by Mark Solovey and Hamilton Cravens (2012) and Working Knowledge: Making the Human Sciences From Parsons to Kuhn by Joel Isaac (see record 2012-13212-000). Taken together, these two important books make intriguing statements about the way to write the histories of fields like psychology, sociology, anthropology, and economics in the Anglo American world during the 20th century. To date, histories of these fields have drawn on a number of fairly well-established punctuation marks to assist in periodization: the shift from interwar institutionalism in economics to postwar neoclassicism, with its physics-like emphasis on mathematical theory-building; the transition from the regnant prewar behaviorism through a postwar "cognitive revolution" in American psychology; and the move in fields like sociology and anthropology away from positivism and the pursuit of what has sometimes been called "grand theory" in the early postwar era toward a period defined by intellectual and political fragmentation, the reemergence of interpretive approaches and a reaction to the scientistic pretensions of the earlier period. These books, by contrast, provide perspectives orthogonal to such existing narrative frameworks by adopting cross-cutting lenses like the "Cold War" and the working practices of researchers in the social and behavioral sciences. As a result, they do much to indicate the value of casting a historiographical net beyond individual disciplines, or even beyond the "social sciences" or the "human sciences" sensu stricto, in the search for deeper patterns of historical development in these fields.

The purpose of the workshop was to bring together leading scientists in four research areas with active fundamental science research at Sandia’s Z facility: Magnetized Liner Inertial Fusion (MagLIF), Planetary Science, Astrophysics, and Material Science. The workshop was focused on discussing opportunities for high-­impact research using Sandia’s Z machine, a future 100 GPa class facility, and possible topics for growing the academic (off-Z-campus) science relevant to the Z Fundamental Science Program (ZFSP) and related projects in astrophysics, planetary science, MagLIF- relevant magnetized HED science, and materials science. The user meeting was for Z collaborative users to: a) hear about the Z accelerator facility status and plans, b) present the status of their research, and c) be provided with a venue to meet and work as groups. Following presentations by Mark Herrmann and Joel Lash on the fundamental science program on Z and the status of the Z facility where plenary sessions for the four research areas. The third day of the workshop was devoted to breakout sessions in the four research areas. The plenary-­ and breakout sessions were for the four areas organized by Dan Sinars (MagLIF), Dylan Spaulding (Planetary Science), Don Winget and Jim Bailey (Astrophysics), and Thomas Mattsson (Material Science). Concluding the workshop were an outbrief session where the leads presented a summary of the discussions in each working group to the full workshop. A summary of discussions and conclusions from each of the research areas follows and the outbrief slides are included as appendices.

    Purpose: Added filtration such as tin filter has the potential to improve dose efficiency of x-ray beam in lung-cancer screening CT. However, dose efficiency with added beam filtration is highly dependent on patient attenuation level. In this phantom study, we evaluated the image quality at different tube voltages with and without added tin filter when attenuation level varies. Methods: A 30 x 20 cm anthropomorphic thorax phantom with three added extension rings were used to simulate small (S), medium (M), large (L), and extra-large (XL) adult patients. These phantoms were scanned on a 192-slice CT scanner (Force, Siemens) at 100 and 120kV without tin filtration, and 100 and 150 kV with tin filtration (100Sn and 150Sn), at multiple dose levels at each kV. Images were reconstructed using iterative reconstruction (ADMIRE, Siemens). Radiation dose was measured with a 0.6 cc ion chamber in the middle and peripheral areas of the phantom. Image quality was assessed using mean image noise at uniform areas in the central region and lung. Radiation dose that is required for each kV to match the noise in a routine lung-cancer CT screening technique (120kV, 25 quality reference mAs) was calculated. Results: At each of the four phantom sizes, 100Sn had the lowest noise in both soft tissue and lung. Compared with 120 kV, 100Sn saved 39%–60% dose for the same noise, depending on phantom size. For the XL phantom (50 by 40 cm), 150Sn provided images with the least beam-hardening artifact in peripheral region. Conclusion: For thoracic CT, added tin filtration can provide considerable dose reduction compared with 120 kV. 100Sn provides better dose efficiencies for all phantom sizes, while 150Sn provides better image quality in peripheral region for extra-large patients.

    Like returns of Halley's comet the Olympic games occur periodically, though not as regularly in antiquity. Dates were also imprecise due to the chaotic calendars in use. Reported sightings of comets and eclipses can be used with game dates to help fix ancient events. However some reported darkening of the sun, e.g., after Julius Caesar's murder in 44 BC, was due to volcanic eruptions. A red comet, visible in daylight, first appeared during the games that year. It was also seen from China and Korea (Pang, Sciences 31, 30). Phlegon's ``Olympiads" (2nd century) says that Christ's crucifixion was in the 4th year of the 202nd Olympiad (AD 29-33), when a total solar eclipse occurred in the 6th hour. Only the Nov. 24, AD 29 eclipse over Asia Minor can match that, and Joel's prophecy (Acts 2, 14-21) that ``the sun will be turned to darkness and moon to blood." However it conflicts with ``the first day of Passover," as recorded by Mathew, Mark and Luke, i.e., full moon in early spring. Humphreys and Waddington (Nature 306, 743) have suggested meteorological darkening and the April 3, AD 33 lunar eclipse instead. Schaefer has questioned the eclipse's visibility from Jerusalem (31.46N, 35.14E). The six computations he cited gave dissimilar answers due to the imprecise rates of the secular lunar acceleration, and lengthening of the day used (Q.Jl.R.astr.Soc. 31, 53). Lunar laser ranging has since fixed the former at -26"/cen2. Analysis of ancient Chinese solar eclipse records, e.g., the April 21, 899 BC and April 4, AD 368 ``double dawns" over Zheng, has given us a delta T (in sec) = 30t2, where t is centuries before 1800 (Pang, Yau and Chou, in ``Dynamics of Ice Age Earth: A Modern Perspective," 1998). Our computations show that the moon rose over Jerusalem, with 1/3 still in the umbra and the rest in penumbra. Holdover meteorological darkening with long absorption air mass could have help reddened the moon also. Finally the first ``eclipse season" (the Aug. 21 lunar, and

  4. Potential disturbance interactions with a single IGV in an F109 turbofan engine

    NASA Astrophysics Data System (ADS)

    Kirk, Joel F.

    A common cause of aircraft engine failure is the high cycle fatigue of engine blades and stators. One of the primary causes of these failures is due to blade row interactions, which cause an aerodynamic excitation to be resonant with a mechanical natural frequency. Traditionally, the primary source of such aerodynamic excitations has been practically limited to viscous wakes from upstream components. However, more advanced designs require that blade rows be very highly loaded and closely spaced. This results in aerodynamic excitation from potential fields of down stream engine components, in addition to the known wake excitations. An experimental investigation of the potential field from the fan of a Honeywell F109 turbofan engine has been completed. The investigation included velocity measurements upstream of the fan, addition of an airfoil shaped probe upstream of the fan on which surface pressure measurements were acquired, and measurement of the velocity in the interaction region between the probe and the fan. This investigation sought to characterize the response on the upstream probe due to the fan potential field and the interaction between a viscous wake and the potential field; as such, all test conditions were for subsonic fan speeds. The results from the collected data show that fan-induced potential disturbances propagate upstream at acoustic velocities, to produce vane surface-pressure amplitudes as high as 40 percent Joel F. Kirk of the inlet, mean total pressure. Further, these fan-induced pressure amplitudes display large variations between the two vane surfaces. An argument is made that the structure of the pressure response is consistent with the presence of two distinct sources of unsteady forcing disturbances. The disturbances on the incoming-rotation-facing surface of the IGV propagated upstream at a different speed than those on the outgoing-rotation-facing surface, indicating that one originated from a rotating source and the other from a

    We analyze both long and short high resolution ultraviolet spectrum of Beta Lyrae eclipsing binary system observed with the International Ultraviolet Explorer (IUE) between 1980 and 1989. The main spectral features are P Cygni profiles originating from different environments of Beta Lyrae. A set of 23 Mg II k&h spectral lines at 2800 Å, originating from the extended envelope [Hack, M., 1980. IAUS, 88, 271H], have been identified and measured to determine their fluxes and widths. We found that there is spectral variability for these physical parameters with phase, similar to that found for the light curve [Kondo, Y., McCluskey, G.E., Jeffery, M.M.S., Ronald, S.P., Carolina, P.S. McCluskey, Joel, A.E., 1994. ApJ, 421, 787], which we attribute to the eclipse effects [Ak, H., Chadima, P., Harmanec, P., Demircan, O., Yang, S., Koubský, P., Škoda, P., Šlechta, M., Wolf, M., Božić, H., 2007. A&A, 463, 233], in addition to the changes of density and temperature of the region from which these lines are coming, as a result of the variability of mass loss from the primary star to the secondary [Hoffman, J.L., Nordsieck, K.H., Fox, G.K., 1998. AJ, 115, 1576; Linnell, A.P., Hubeny, I., Harmanec, P., 1998. ApJ, 509, 379]. Also we present a study of Fe II spectral line at 2600 Å, originating from the atmosphere of the primary star [Hack, M., 1980. IAUS, 88, 271H]. We found spectral variability of line fluxes and line widths with phase similar to that found for Mg II k&h lines. Finally we present a study of Si IV spectral line at 1394 Å, originating from the extended envelope [Hack, M., 1980. IAUS, 88, 271H]. A set of 52 Si IV spectral line at 1394 Å have been identified and measured to determine their fluxes and widths.

Dr. Gulati was the first recipient of The Stanford Geothermal Program Reservoir Engineering Award for Excellence in Development of Geothermal Energy. Dr. Frank Miller presented the award. The registered attendance figure of one hundred fifteen participants was up slightly from last year. There were seven foreign countries represented: Iceland, Italy, Philippines, Kenya, the United Kingdom, Mexico, and Japan. As last year, papers on about a dozen geothermal fields outside the United States were presented. There were thirty-six papers presented at the Workshop, and two papers were submitted for publication only. Attendees were welcomed by Dr. Khalid Aziz, Chairman of the Petroleum Engineering Department at Stanford. Opening remarks were presented by Dr. Roland Horne, followed by a discussion of the California Energy Commission's Geothermal Activities by Barbara Crowley, Vice Chairman; and J.E. ''Ted'' Mock's presentation of the DOE Geothermal Program: New Emphasis on Industrial Participation. Technical papers were organized in twelve sessions concerning: hot dry rock, geochemistry, tracer injection, field performance, modeling, and chemistry/gas. As in previous workshops, session chairpersons made major contributions to the program. Special thanks are due to Joel Renner, Jeff Tester, Jim Combs, Kathy Enedy, Elwood Baldwin, Sabodh Garg, Marcel0 Lippman, John Counsil, and Eduardo Iglesias.

    PREFACE The Nineteenth Workshop on Geothermal Reservoir Engineering was held at Stanford University on January 18-20, 1994. This workshop opened on a sad note because of the death of Prof. Henry J. Ramey, Jr. on November 19, 1993. Hank had been fighting leukemia for a long time and finally lost the battle. Many of the workshop participants were present for the celebration of his life on January 21 at Stanford's Memorial Church. Hank was one of the founders of the Stanford Geothermal Program and the Geothermal Reservoir Engineering Workshop. His energy, kindness, quick wit, and knowledge will long be missed at future workshops. Following the Preface we have included a copy of the Memorial Resolution passed by the Stanford University Senate. There were one hundred and four registered participants. Participants were from ten foreign countries: Costa Rica, England, Iceland, Italy, Japan, Kenya, Mexico, New Zealand, Philippines and Turkey. Workshop papers described the performance of fourteen geothermal fields outside the United States. Roland N. Home opened the meeting and welcomed the visitors to the campus. The key note speaker was J.E. ''Ted'' Mock who gave a presentation about the future of geothermal development. The banquet speaker was Jesus Rivera and he spoke about Energy Sources of Central American Countries. Forty two papers were presented at the Workshop. Technical papers were organized in twelve sessions concerning: sciences, injection, production, modeling, and adsorption. Session chairmen are an important part of the workshop and our thanks go to: John Counsil, Mark Walters, Dave Duchane, David Faulder, Gudmundur Bodvarsson, Jim Lovekin, Joel Renner, and Iraj Ershaghi. The Workshop was organized by the Stanford Geothermal Program faculty, staff, and graduate students. We wish to thank Pat Ota, Ted Sumida, and Terri A.

    Six Socorro High School students are spending their summer working at the National Radio Astronomy Observatory (NRAO) on a unique project that gives them experience in language translation, World Wide Web design, and technical communication. Under the project, called "Un puente a los cielos," the students are translating many of NRAO's Web pages on astronomy into Spanish. "These students are using their bilingual skills to help us make basic information about astronomy and radio telescopes available to the Spanish-speaking community," said Kristy Dyer, who works at NRAO as a National Science Foundation postdoctoral fellow and who developed the project and obtained funding for it from the National Aeronautics and Space Administration. The students are: Daniel Acosta, 16; Rossellys Amarante, 15; Sandra Cano, 16; Joel Gonzalez, 16; Angelica Hernandez, 16; and Cecilia Lopez, 16. The translation project, a joint effort of NRAO and the NM Tech physics department, also includes Zammaya Moreno, a teacher from Ecuador, Robyn Harrison, NRAO's education officer, and NRAO computer specialist Allan Poindexter. The students are translating NRAO Web pages aimed at the general public. These pages cover the basics of radio astronomy and frequently-asked questions about NRAO and the scientific research done with NRAO's telescopes. "Writing about science for non-technical audiences has to be done carefully. Scientific concepts must be presented in terms that are understandable to non-scientists but also that remain scientifically accurate," Dyer said. "When translating this type of writing from one language to another, we need to preserve both the understandability and the accuracy," she added. For that reason, Dyer recruited 14 Spanish-speaking astronomers from Argentina, Mexico and the U.S. to help verify the scientific accuracy of the Spanish translations. The astronomers will review the translations. The project is giving the students a broad range of experience. "They are

These data reveal emission from gas rich in oxygen and nitrogen but no hydrogen, a rare set of signals from globular clusters. The physical conditions deduced from the spectra suggest that the gas is orbiting a black hole of at least 1,000 solar masses. The abundant amount of oxygen and absence of hydrogen indicate that the destroyed star was a white dwarf, the end phase of a solar-type star that has burned its hydrogen leaving a high concentration of oxygen. The nitrogen seen in the optical spectrum remains an enigma. "We think these unusual signatures can be explained by a white dwarf that strayed too close to a black hole and was torn apart by the extreme tidal forces," said coauthor Joel Bregman of the University of Michigan. Theoretical work suggests that the tidal disruption-induced X-ray emission could stay bright for more than a century, but it should fade with time. So far, the team has observed there has been a 35% decline in X-ray emission from 2000 to 2008. The ULX in this study is located in NGC 1399, an elliptical galaxy about 65 million light years from Earth. Irwin presented these results at the 215th meeting of the American Astronomical Society in Washington, DC.

Normally, the distances between stars in galaxies are too great for capture to occur, but in the extraordinarily dense environment of globular clusters they may be much more common.

GEM constitutes greater than 99% of the mercury mass in most rural and remote locations. While dry and wet deposition of atmospheric mercury is thought to be dominated by oxidized mercury (a.k.a. reactive mercury), only small GEM uptake to environmental surfaces could impact the input of mercury to terrestrial and aquatic ecosystems. Dry deposition and subsequent re-emission of gaseous elemental mercury is a pathway from the atmosphere that remains only partially understood from a mechanistic perspective. In order to properly model GEM dry deposition and re-emission an understanding of its dependence on irradiance, temperature, and relative humidity must be measured and parameterized for a broad spectrum of environmental surfaces colocated with surrogate deposition surfaces used to make field based dry deposition measurements. Measurements of isotopically enriched GEM dry deposition were made with a variety of environmental surfaces in a controlled environment room at the University of Wisconsin Biotron. The experimental set up allowed dry deposition components which are not easily separated in the field to be decoupled. We were able to isolate surface transfer processes from variabilities caused by

Smog chamber experiments were then conducted in the PSI facilities to investigate the aging of biomass burning emissions. The analysis of samples collected during these experiments using the DART/Q-ToF approach, confirmed that nitrocatechols and methylated nitrocatechols originate from biomass burning processes. More importantly our results confirm that nitrocatechols and their methylated derivatives are quasi exclusively from secondary origin. Considering the abundance of biomass burning primary aerosol, and the large fraction of unexplained SOA, this result is of prime importance. Cody. R., Laramée J.

  15. Volatile History of the Bishop Tuff from Apatite Phenocrysts and Inclusions

    NASA Astrophysics Data System (ADS)

    Apatite is a common mineral found in a wide variety of volcanic rocks and contains all of the volatile elements within its structure as either major or minor components. Such characteristics make apatite a useful tool for developing a better understanding of complex magmatic systems and their evolution. For some elements, such as F, Cl, and OH, an apatite phenocryst can participate in chemical exchange within the magma chamber on very short timescales (Brenan, 1993, Chem. Geol.), thus giving insight into the volatiles in the system immediately prior to eruption. For other elements (including S), natural and experimental data indicate that variations can be preserved for longer timescales, potentially providing a different, yet equally interesting record. With an especially well-studied ignimbrite and air fall sequence and previously published melt inclusion work, the Bishop Tuff is an ideal system in which to test the utility of apatite crystals for studying volatile evolution of a large volume magma body. The Bishop Tuff has a nine unit air fall sequence (Wilson and Hildreth, 1997, 2003, J. Geol.) from which three units were chosen to represent early (unit #2), middle (#5), and late (#8) air fall periods. Along with apatite phenocrysts, apatite inclusions within zircon phenocrysts were used to investigate the prospect that a host could protect the crystal from volatile exchange with the melt in a manner analogous to melt inclusions. This would potentially extend the record deeper into the history of the magma. Fifty analyses of volatile, major, and trace elements were performed at UCLA using the JOEL JXA-8200 electron microprobe. Apatite phenocrysts from the Bishop Tuff are very poor in Cl with measured values (<200 ppm), often within error of zero. In these same crystals, we observe S-depleted rims (<2000 ppm) and S-rich cores (>4500 ppm), possibly representing an earlier magmatic phase, or xenocrystic remnants. Interestingly, we observe similar S variations in

    The astronomical community lost one of its most buoyant and caring individuals when Beth Brown died, unexpectedly, at the age of 39 from a pulmonary embolism. Beth Brown was born in Roanoke, Virginia where she developed a deep interest in astronomy, science, and science fiction (Star Trek). After graduating as the valedictorian of William Fleming High School's Class of 1987, she attended Howard University, where she graduated summa cum laude in 1991 with a bachelor's degree in astrophysics. Following a year in the graduate physics program at Howard, she entered the graduate program in the Department of Astronomy at the University of Michigan, the first African-American woman in the program. She received her PhD in 1998, working with X-ray observations of elliptical galaxies from the Röntgen Satellite (ROSAT; Joel Bregman was her advisor). She compiled and analyzed the first large complete sample of such galaxies with ROSAT and her papers in this area made an impact in the field. Following her PhD, Beth Brown held a National Academy of Science & National Research Council Postdoctoral Research Fellowship at NASA's Goddard Space Flight Center. Subsequently, she became a civil servant at the National Space Science Data Center at GSFC, where she was involved in data archival activities as well as education and outreach, a continuing passion in her life. In 2006, Brown became an Astrophysics Fellow at GSFC, during which time she worked as a visiting Assistant Professor at Howard University, where she taught and worked with students and faculty to improve the teaching observatory. At the time of her death, she was eagerly looking forward to a new position at GSFC as the Assistant Director for Science Communications and Higher Education. Beth Brown was a joyous individual who loved to work with people, especially in educating them about our remarkable field. Her warmth and openness was a great aid in making accessible explanations of otherwise daunting astrophysical

    Two new, large gas-giant exoplanets have been discovered orbiting close to their host stars. A recent study examining these planets and others like them may help us to better understand what happens to close-in hot Jupiters as their host stars reach the end of their main-sequence lives.OversizedGiantsUnbinned transit light curves for HAT-P-65b. [Adapted from Hartman et al. 2016]The discovery of HAT-P-65b and HAT-P-66b, two new transiting hot Jupiters, is intriguing. These planets have periods of just under 3 days and masses of roughly 0.5 and 0.8 times that of Jupiter, but their sizes are whats really interesting: they have inflated radii of 1.89 and 1.59 times that of Jupiter.These two planets, discovered using the Hungarian-made Automated Telescope Network (HATNet) in Arizona and Hawaii, mark the latest in an ever-growing sample of gas-giant exoplanets with radii larger than expected based on theoretical planetary structure models.What causes this discrepancy? Did the planets just fail to contract to the expected size when they were initially formed, or were they reinflated later in their lifetimes? If the latter, how? These are questions that scientists are only now starting to be able to address using statistics of the sample of close-in, transiting planets.Unbinned transit light curves for HAT-P-66b. [Hartman et al. 2016]Exploring Other PlanetsLed by Joel Hartman (Princeton University), the team that discovered HAT-P-65b and HAT-P-66b has examined these planets observed parameters and those of dozens of other known close-in, transiting exoplanets discovered with a variety of transiting exoplanet missions: HAT, WASP, Kepler, TrES, and KELT. Hartman and collaborators used this sample to draw conclusions about what causes some of these planets to have such large radii.The team found that there is a statistically significant correlation between the radii of close-in giant planets and the fractional ages of their host stars (i.e., the stars age divided by its full

  18. X-Ray Outburst from Young Star in McNeil's Nebula

    NASA Astrophysics Data System (ADS)

    2004-07-01

    Observations with NASA's Chandra X-ray Observatory captured an X-ray outburst from a young star, revealing a probable scenario for the intermittent brightening of the recently discovered McNeil's Nebula. It appears the interaction between the young star's magnetic field and an orbiting disk of gas can cause dramatic, episodic increases in the light from the star and disk, illuminating the surrounding gas. "The story of McNeil's Nebula is a wonderful example of the importance of serendipity in science," said Joel Kastner of the Rochester Institute of Technology in Rochester, New York, lead author of a paper in the July 22 issue of Nature describing the X-ray results. "Visible-light images were made of this region several months before Jay McNeil made his discovery, so it could be determined approximately when and by how much the star flared up to produce McNeil's Nebula." The small nebula, which lies in the constellation Orion about 1300 light years from Earth, was discovered with a 3-inch telescope by McNeil, an amateur astronomer from Paducah, Kentucky, in January 2004. In November 2002, a team led by Ted Simon of the Institute for Astronomy in Hawaii had observed the star-rich region with Chandra in search of young, X-ray emitting stars, and had detected several objects. Optical and infrared astronomers had, as part of independent surveys, also observed the region about a year later, in 2003. After the announcement of McNeil's discovery, optical, infrared and X-ray astronomers rushed to observe the region again. They found that a young star buried in the nebula had flared up, and was illuminating the nebula. This star was coincident with one of the X-ray sources discovered earlier by Simon. Chandra observations obtained by Kastner's group just after the optical outburst showed that the source had brightened fifty-fold in X-rays when compared to Simon's earlier observation. The visible-light eruption provides evidence that the cause of the X-ray outburst is the

  19. Astronomers Find New Evidence for the Violent Demise of Sun-like Stars

    NASA Astrophysics Data System (ADS)

    2005-06-01

    Two astronomers have used NASA's Chandra X-ray Observatory to discover a shell of superheated gas around a dying star in the Milky Way galaxy. Joel Kastner, professor of imaging science at the Rochester Institute of Technology, and Rodolpho Montez, a graduate student in physics and astronomy at the University of Rochester, will present their results today at the American Astronomical Society meeting in Minneapolis. Their discovery shows how material ejected at two million miles per hour during the final, dying stages of sun-like stars can heat previously ejected gas to the point where it will emit X-rays. The study also offers new insight into how long the ejected gas around dying stars can persist in such a superheated state. According to Kastner, the hot gas shows up in high-resolution Chandra X-ray images of the planetary nebula NGC 40, which is located about 3,000 light years away from Earth in the direction of the constellation Cepheus. Chandra X-ray & NOAO Optical Composite of NGC 40 Chandra X-ray & NOAO Optical Composite of NGC 40 "Planetary nebulae are shells of gas ejected by dying stars," Kastner explains. "They offer astronomers a 'forecast' of what could happen to our own sun about five billion years from now - when it finally exhausts the reservoir of hydrogen gas at its core that presently provides its source of nuclear power." In his research, Montez discovered the X-ray emitting shell in NGC 40 by generating an image that uses only specific energy-selected X-rays - revealing a ring of superheated gas that lies just within the portions of the nebula that appear in optical and infrared images. "This hot bubble of gas vividly demonstrates how, as a planetary nebula forms, the gas ejection process of the central, dying star becomes increasingly energetic," Kastner notes. "Mass ejection during stellar death can result in violent collisions that can heat the ejected gas up to temperatures of more than a million degrees." The detection of X-rays from NGC

    nitric acid solution . After an incorporation time, a fraction of this sample was then diluted 20 times in ultrapure deionized water ( resistivity greater 18.2 megohms / cm ). The diluted sample was analized in the ICP- MS, which was setted in high sensitivity mode. The results were compared through cross samples (the same samples tested in the laboratory were sent to another international laboratory, which works under accreditation ISO 17025 ) and no major deviations (5%) was obtained by making comparisons between the two laboratories. When comparing the results and evaluated the development of the art, it is concluded that this is an alternative that allows performing samples up to 50 alkaline fusions per day with great accuracy, saving resources and time.

    The quest for the nature of dark matter has reached a historical point in time, with several different and complementary experiments on the verge of conclusively exploring large portions of the parameter space of the most theoretically compelling particle dark matter models. This focus issue on dark matter and particle physics brings together a broad selection of invited articles from the leading experimental and theoretical groups in the field. The leitmotif of the collection is the need for a multi-faceted search strategy that includes complementary experimental and theoretical techniques with the common goal of a sound understanding of the fundamental particle physical nature of dark matter. These include theoretical modelling, high-energy colliders and direct and indirect searches. We are confident that the works collected here present the state of the art of this rapidly changing field and will be of interest to both experts in the topic of dark matter as well as to those new to this exciting field.

  2. Chandra Adds to Story of the Way We Were

    NASA Astrophysics Data System (ADS)

    2003-05-01

    Data from NASA's Chandra X-ray Observatory have enabled astronomers to use a new way to determine if a young star is surrounded by a planet-forming disk like our early Sun. These results suggest that disks around young stars can evolve rapidly to form planets, or they can be disrupted by close encounters with other stars. Chandra observed two young star systems, TW Hydrae and HD 98800, both of which are in the TW Hydrae Association, a loose cluster of 10 million-year-old stars. Observations at infrared and other wavelengths have shown that several stars in the TW Hydrae Association are surrounded by disks of dust and gas. At a distance of about 180 light years from Earth, these systems are among the nearest analogs to the early solar nebula from which Earth formed. "X-rays give us an excellent new way to probe the disks around stars," said Joel Kastner of the Rochester Institute of Technology in Rochester, NY during a press conference today in Nashville, Tenn. at a meeting of the American Astronomical Society. "They can tell us whether a disk is very near to its parent star and dumping matter onto it, or whether such activity has ceased to be important. In the latter case, presumably the disk has been assimilated into larger bodies - perhaps planets--or disrupted." TW Hydrae and HD 98800A Chandra 0th Order Image of HD98800 Kastner and his colleagues found examples of each type of behavior in their study. One star, TW Hydrae, namesake of the TW Hydrae Association, exhibited features in its X-ray spectrum that provide strong, new evidence that matter is accreting onto the star from a circumstellar disk. They concluded that matter is guided by the star's magnetic field onto one or more hot spots on the surface of the star. In contrast, Chandra observations of the young multiple star system HD 98800 revealed that its brightest star, HD 98800A, is producing X-rays much as the Sun does, from a hot upper atmosphere or corona. HD 98800 is a complex multiple-star system

    2015-04-01

    The paper is devoted to results of doctoral research work at University of Bochum as applied to the radar transmission experiment CONSERT of the ESA cometary mission Rosetta. This research aims at achieving the limits of optimum spatial (and temporal) resolution for radar remote sensing by implementation of covariance informations concerned with error-balanced control as well as coherence of wave propagation effects through random composite media involved (based on Joel Franklin's approach of extended stochastic inversion). As a consequence the well-known inherent numerical instabilities of remote sensing are significantly reduced in a robust way by increasing the weight of main diagonal elements of the resulting composite matrix to be inverted with respect to off-diagonal elements following synergy relations as to the principle of correlation receiver in wireless telecommunications. It is shown that the enhancement of resolution for remote sensing holds for an integral and differential equation approach of inversion as well. In addition to that the paper presents a discussion on how the efficiency of inversion for radar data gets achieved by an overall optimization of inversion due to a novel neuro-genetic approach. Such kind of approach is in synergy with the priority research program "Organic Computing" of DFG / German Research Organization. This Neuro-Genetic Optimization (NGO) turns out, firstly, to take into account more detailed physical informations supporting further improved resolution such as the process of accretion for cometary nucleus, wave propagation effects from rough surfaces, ground clutter, nonlinear focusing, etc. as well as, secondly, to accelerate the computing process of inversion in a really significantly enhanced and fast way, e.g., enabling online-control of autonomous processes such as detection of unknown objects, navigation, etc. The paper describes in some detail how this neuro-genetic approach of optimization is incorporated into the

    detailed analysis of the so- called Slab-model, and re-acceleration of cosmic rays (Shapiro, Silberberg, and Tsao in Cosmology, Fusion and other Matters, edited by Fred Reines, 1972). When he became emeritus, Maury was still very active both in research and in running the Erice School of Cosmic Ray Astrophysics (after 1982). He was interested in having a base of operations for the school. He approached me asking whether Maryland would be a possibility. I was delighted and suggested a Visiting professorship to be able to continue his work (without having to move out of the Washington, DC, area). Thus started Maury's association with Maryland which continued until his death. Maury was not only an outstanding scientist, but he was a true gentleman and a good friend. He was an ambassador for the field of Cosmic Rays. His friendly personality, always warm and kind to students and colleagues, was quite infectious. Maury contributed to both experimental and theoretical investigations of cosmic rays and their central role in connecting many diverse disciplines in particle physics, astrophysics, geophysics, acoustical physics. He was outstanding scientist and was greatly concerned about world peace and human affairs. Maury passed away on 27 February 2008, at the age of 92, in Alexandria, Virginia. Four years prior to his death he was still swimming in the Mediterranean during the Cosmic Ray School sessions at Erice. He is survived by his wife, Ruth Auslander, and children Joel N. Shapiro, Elana Ashley, Raquel T. Kislinger, Mark and Bonnie Auslander, Beth Kessler, Lionel Ames, and Naomi Mirvis and grand children.

    This final report is presented by Langston University (LU) for the project entitled "Langston University High Energy Physics" (LUHEP) under the direction of principal investigator (PI) and project director Professor Joel Snow. The project encompassed high energy physics research performed at hadron colliders. The PI is a collaborator on the DZero experiment at Fermi National Accelerator Laboratory in Batavia, IL, USA and the ATLAS experiment at CERN in Geneva, Switzerland and was during the entire project period from April 1, 1999 until May 14, 2012. Both experiments seek to understand the fundamental constituents of the physical universe and the forces that govern their interactions. In 1999 as member of the Online Systems group for Run 2 the PI developed a cross-platform Python-based, Graphical User Interface (GUI) application for monitoring and control of EPICS based devices for control room use. This served as a model for other developers to enhance and build on for further monitoring and control tasks written in Python. Subsequently the PI created and developed a cross-platform C++ GUI utilizing a networked client-server paradigm and based on ROOT, the object oriented analysis framework from CERN. The GUI served as a user interface to the Examine tasks running in the D\\O\\ control room which monitored the status and integrity of data taking for Run 2. The PI developed the histogram server/control interface to the GUI client for the EXAMINE processes. The histogram server was built from the ROOT framework and was integrated into the D\\O\\ framework used for online monitoring programs and offline analysis. The PI developed the first implementation of displaying histograms dynamically generated by ROOT in a Web Browser. The PI's work resulted in several talks and papers at international conferences and workshops. The PI established computing software infrastructure at LU and U. Oklahoma (OU) to do analysis of DZero production data and produce simulation data

    research communities have established collaborations between researchers in France and the UK, and both are concerned with the science and applications of ultrasound. Although there are some differences in scope, there is also very significant overlap, and much shared interest. Furthermore, the possibilities to extend contacts between the members in both countries, and between disciplines, was an additional benefit of a joint conference. The suggestion of a joint meeting was therefore met with enthusiasm from both sides. The conference was arranged as a single-stream series of presentations and discussions in the style of a workshop. Four leading authorities in their fields were invited to give 50-minute keynote addresses; these were Joel Gilbert (Université du Maine, France), Peter Wells (Cardiff University, UK), John Willis (Cambridge University, UK), and Philippe Destuynder (Conservatoire National des Arts et Métiers, France). Other participants gave 20-minute oral presentations or posters. There were 82 contributions in total. Participants were given the option to submit manuscripts to be peer-reviewed for publication in these proceedings. The cost of participation at the conference was part-supported by the GDR for all attendees. The conference was a great success, and it was widely acknowledged that it achieved all the hopes for communication, collaboration, and new contacts and opportunities. However, the attendees of the conference are also left with a very sad memory. This was the last working engagement of Andrew Temple, who died suddenly on 6 February 2010. Andrew was the Chairman of the PAG of the Institute of Physics and an enthusiast for both AFPAC and GDR activities. He was the central organiser of this conference, across all aspects, from his technical contributions as a member of the technical committee, to his provision of local information and plans for social activities and outings. He was a highly accomplished and respected scientist who was also a

    Michael John Klein died on 14 May 2005 at home in South Pasadena, California. The cause of death was tongue cancer that metastasized to the lungs. He was a non-smoker. Mike was a passionate radio astronomer, a trusted astronomical observer, an educator and a family man. Mike was born on 19 January 1940 in Ames, Iowa, the son of Florence Marie (Graf) and Fred Michael Klein. His mother was a homemaker, and his father was a banker. Mike had two older sisters, Lois Jean (Klein) Flauher and Marilyn June (Klein) Griffin. In 1962, Mike married his high school sweetheart Barbara Dahlberg, who survives him along with their three children, Kristin Marie (Klein) Shields, Michael John Klein Jr., Timothy Joel Klein, and six grandchildren. Mike developed a love for astronomy early in his life, and credited an early morning, newspaper-delivery route that he had at age twelve, which took him outside well before sunrise. He told family members that as he walked along his route, he stared into the sky and wondered what everything was. He studied sky charts, located stars, and began to understand how the planets shifted their positions relative to the stars each day. Another big influence in Mike's life was his brother in-law, Jim Griffin. Jim helped Mike understand that his passion for science did not have to remain a hobby, but could and should become a career. Jim's encouragement led Mike to attend Iowa State University in Ames, where he earned a BS in electrical engineering in 1962. Mike then started graduate school in electrical engineering at Michigan State, but after one semester transferred to the University of Michigan, Ann Arbor, where he earned an MS (1966) and PhD (1968) in astronomy. His doctoral dissertation, under the direction of Professor Fred Haddock, was based on extensive observations of the planets and examined the physical and thermal properties of planetary atmospheres and surfaces. Mike was awarded a Resident Research Associate position at JPL by the National

After he returned to academic life at Rice in 1973, he collected his notes from a graduate course into the 1978 book Theory of Planetary Atmospheres, a second edition of which appeared in 1987 (with the collaboration of the undersigned). His other interest included early studies of changes in the ozone layer and the possible devastating effects from what has now become recognized as global warming. He is survived by his wife of 54 years, Marilyn; daughter Joy of London; sons David of Austin and Jeffrey (Joel) of Seattle; and granddaughter Jacqueline. His brother Gilbert and numerous nieces and nephews also survive him.

    Joel Franklin's textbook `Advanced Mechanics and General Relativity' comprises two partially overlapping, partially complementary introductory paths into general relativity at advanced undergraduate level. Path I starts with the Lagrangian and Hamiltonian formulations of Newtonian point particle motion, emphasising the action principle and the connection between symmetries and conservation laws. The concepts are then adapted to point particle motion in Minkowski space, introducing Lorentz transformations as symmetries of the action. There follows a focused development of tensor calculus, parallel transport and curvature, using examples from Newtonian mechanics and special relativity, culminating in the field equations of general relativity. The Schwarzschild solution is analysed, including a detailed discussion of the tidal forces on a radially infalling observer. Basics of gravitational radiation are examined, highlighting the similarities to and differences from electromagnetic radiation. The final topics in Path I are equatorial geodesics in Kerr and the motion of a relativistic string in Minkowski space. Path II starts by introducing scalar field theory on Minkowski space as a limit of point masses connected by springs, emphasising the action principle, conservation laws and the energy-momentum tensor. The action principle for electromagnetism is introduced, and the coupling of electromagnetism to a complex scalar field is developed in a detailed and pedagogical fashion. A free symmetric second-rank tensor field on Minkowski space is introduced, and the action principle of general relativity is recovered from coupling the second-rank tensor to its own energy-momentum tensor. Path II then merges with Path I and, supplanted with judicious early selections from Path I, can proceed to the Schwarzschild solution. The choice of material in each path is logical and focused. A notable example in Path I is that Lorentz transformations in Minkowki space are introduced

  12. X-rays Signal Presence of Elusive Intermediate-Mass Black Hole

    NASA Astrophysics Data System (ADS)

    2005-03-01

    regular stellar-mass black holes that appear to be much more powerful in X-rays because their radiation is beamed in a jet toward Earth. Chandra's discovery of the persistence and long time period of the X-ray variations (called quasi-periodic oscillations, because they are not strictly periodic) of the ULX in M74 is an argument against a beamed jet. These variations are likely produced by changes in a disk of hot gas around the black hole. More massive black holes have larger disks, which in turn are expected to vary over longer periods. Full-Field Optical Image of M74 Full-Field Optical Image of M74 Independent observations of a wide range of black hole X-ray sources with masses ranging from ten to tens of millions solar masses have revealed a relationship between the time scale of quasi-periodic oscillations and the mass of the underlying black hole. Using this technique, the observed two-hour variation implies that this ULX has a mass of about 10,000 Suns. Such a large mass would place this black hole well above the stellar-mass black hole limit of a few dozen solar masses. How then did it form? The leading theories under consideration are that intermediate-mass black holes form as dozens or even hundreds of black holes merge in the center of a dense star cluster, or that they are the remnant nuclei of small galaxies that are in the process of being absorbed by a larger galaxy. Chandra observed M74, which is in the constellation of Pisces, twice: once in June 2001 and again in October 2001. The European Space Agency's XMM-Newton satellite also observed this object in February 2002 and January 2003. Other authors on the research paper are Joel Bregman, Ed Lloyd-Davies, Jimmy Irwin, Catherine Espaillat, and Patrick Seitzer, all of the University of Michigan in Ann Arbor. Miriam Krauss (Massachusetts Institute of Technology), Roy Kilgard (Univ. of Leicester and Smithsonian Astrophysical Observatory) and their colleagues have also reported extreme variability and the

    Baseline Interferometry project at JPL. "Observations of cosmic masers -- naturally-occurring microwave radio amplifiers -- will tell us new things about the process of star formation and activity in the heart of other galaxies." "By the 1980s, radio astronomers were observing the universe with assemblages of radio telescopes whose resolving power was limited only by the size of the Earth. Now, through a magnificent international effort, we will be able to break this barrier and see fine details of celestial objects that are beyond the reach of a purely ground-based telescope array. We anticipate a rich harvest of new scientific knowledge from VSOP," said Dr. Paul Vanden Bout, Director of NRAO. In the first weeks after launch, scientists and engineers will "test the deployment of the reflecting mesh telescope in orbit, the wide-band data link from the satellite to the ground, the performance of the low noise amplifiers in orbit, and the high-precision orbit determination and attitude control necessary for VLBI observations with an orbiting telescope," according to Dr. Joel Smith, manager of the U.S. Space VLBI project at JPL. Scientific observations are expected to begin in May. The 26-foot diameter orbiting radio telescope will observe celestial radio sources in concert with a number of the world's ground-based radio telescopes. The 1,830-pound satellite will be launched from ISAS' Kagoshima Space Center, at the southern tip of Kyushu, one of Japan's main islands, and will be the first launch with ISAS' new M-5 series rocket. The satellite will go into an elliptical orbit, varying between 620 to 12,400 miles above the Earth's surface. This orbit provides a wide range of distances between the satellite and ground-based telescopes, which is important for producing a high-quality image of the radio source being observed. One orbit of the Earth will take about six hours. The satellite's observations will concentrate on some of the most distant and intriguing objects in the

"And by extreme, we mean temperatures which are in some cases well above 60 million degrees." The hottest massive star known so far has been around 25 million degrees. The great Orion Nebula harbors the Orion Nebula Cluster (ONC), a loose association of around 2,000 mostly very young stars of a wide range of mass confined within a radius of less than 10 light years. The Orion Trapezium Cluster is a younger subgroup of stars at the core of the ONC confined within a radius of about 1.5 light years. Its median age is around 300,000 years. The constant bright light of the Trapezium and its surrounding stars at the heart of the Orion nebula (M42) are visible to the naked eye on clear nights. In X-rays, these young stars are constantly active and changing in brightness, sometimes within half a day, sometimes over weeks. "Never before Chandra have we seen images of stellar activity with such brilliance," said Joel Kastner, professor at the Chester F. Carlson Center for Imaging Science at the Rochester Institute of Technology. "Here the combination of very high angular resolution, with high quality spectra that Chandra offers, clearly pays off." The observation was performed using the High Energy Transmission Grating Spectrometer (HETGS) and the X-ray spectra were recorded with the spectroscopic array of the Advanced CCD Imaging Spectrometer (ACIS). The ACIS detector is a sophisticated version of the CCD detectors commonly used in video cameras or digital cameras. The orion stars are so bright in X-rays that they easily saturate the ccds.

    tendency to prefer sugars and proteins that are one chirality only, but it is unknown whether this is a universal preference or a quirk of Earth-based life. Carroll and McGuires new detection in a star-forming cloud of material near the center of the Milky Way does not distinguish whether the propylene oxide is left- or right-handed, but it does show that the cosmos is capable of producing complex molecules that are essential to biology. In the future, they hope to use polarized light to directly measure chirality.Next, Joel Green from STScI presented how a young star surrounded by a bright protoplanetary disk, FU Orionis, has changed since a bright outburst in 1936. Since then, it has consumed some 80 Jupiters worth of material! By comparing observations of the disks brightness taken twelve years apart, Green showed that the hottest inner regions of the disk have faded significantly while the cooler regions farther out have not. In other words, the star has consumed the hot parts of the disk closest to it and altered the chemical composition in the disk that remains. This is likely what our own Sun experienced as a young star, and has implications for planet formation because the chemical composition of the disk affects what materials are available for forming planets. Green hopes that future observations with the Webb telescope will complement existing Spitzer and SOFIA data.A gluttonous star may hold clues to #planet formation: https://t.co/bTcFJM3xcY#aas228pic.twitter.com/nDWLF3bXVN NASA PlanetQuest (@PlanetQuest) June 14, 2016

Westphall1, Audrey P. Gasch1, Joshua J. Coon1 1University of Wisconsin-Madison, Madison, WI, USA; 2Cambridge Isotope Laboratories, Andover, MA, USA Modern biological and medicinal researchers increasingly rely on large-scale technologies for the comparative analysis of proteomes. To satisfy this growing demand, maturing proteomic methods must achieve high-throughput, quantitative analyses of near-complete proteomes. Here we describe two efforts in this vein. The first is the identification of ∼4,000 yeast proteins, a comprehensive yeast proteome, from just over an hour of analysis time. We achieved this expedited proteome characterization through improved sample preparation, chromatographic separations, and by using a new Orbitrap hybrid mass spectrometer equipped with a mass filter, a collision cell, a high-field Orbitrap analyzer, and, finally, a dual cell linear ion trap analyzer (Q-OT-qIT, Orbitrap Fusion). The second is a quantitative approach that blends the accuracy of SILAC with the impressive throughput of isobaric tagging methods. The strategy – neutron encoding (NeuCode) – relies on the mass defect of atoms and their isotopes and harnesses the exceptional resolving power of modern FT-MS systems to selectively reveal or conceal quantitative information when desired. Recently, a new Orbitrap hybrid mass spectrometer comprised of a mass filter, a collision cell, a high-field Orbitrap analyzer, and a dual cell linear ion trap analyzer was introduced (Q
