    @@ Lin: In October 2003, U.S. Goldman Sachs Group. Inc. issued a report entitled "Dreaming with BRICs: The Path to 2050" that evoked huge response in the world. What interest us are not only the BRICs phenomenon, but also China on the list of BRICs. The report made high-sounding prediction of the economic prospects of Brazil, Russia and India. Its predict of China's economic prospect is also interesting. Therefore we attach importance to the report and conclusion thereof. Today we will hold a discussion on the report. Now let us begin our discussion.

    We define a Poisson Algebra called the {\\em swapping algebra} using the intersection of curves in the disk. We interpret a subalgebra of the fraction algebra of the swapping algebra -- called the {\\em algebra of multifractions} -- as an algebra of functions on the space of cross ratios and thus as an algebra of functions on the Hitchin component as well as on the space of $\\mathsf{SL}_n(\\mathbb R)$-opers with trivial holonomy. We relate this Poisson algebra to the Atiyah--Bott--Goldman symple...

    2003-09-01

    Full Text Available Goldman points of a topological space are defined in order to extend the notion of prime G-ideals of a ring. We associate to any topological space a new topology called Goldman topology. For sober spaces, we prove an extension theorem of continuous maps. As an application, we give a topological characterization of the Jacobson subspace of the spectrum of a commutative ring. Many examples are provided to illustrate the theory.

    Foster, Peter C

    2014-01-01

    Because elementary mathematics is vital to be able to properly design biological experiments and interpret their results. As a student of the life sciences you will only make your life harder by ignoring mathematics entirely. Equally, you do not want to spend your time struggling with complex mathematics that you will never use. This book is the perfect answer to your problems. Inside, it explains the necessary mathematics in easy-to-follow steps, introducing the basics and showing you how to apply these to biological situations. Easy Mathematics for Biologists covers the basic mathematical ideas of fractions, decimals and percentages, through ratio and proportion, exponents and logarithms, to straight line graphs, graphs that are not straight lines, and their transformation. Direct application of each of these leads to a clear understanding of biological calculations such as those involving concentrations and dilutions, changing units, pH, and linear and non-linear rates of reaction. Each chapter contains wo...

    2008-08-01

    This paper describes the open source framework MARVIN for rapid application development in the field of biomedical and clinical research. MARVIN applications consist of modules that can be plugged together in order to provide the functionality required for a specific experimental scenario. Application modules work on a common patient database that is used to store and organize medical data as well as derived data. MARVIN provides a flexible input/output system with support for many file formats including DICOM, various 2D image formats and surface mesh data. Furthermore, it implements an advanced visualization system and interfaces to a wide range of 3D tracking hardware. Since it uses only highly portable libraries, MARVIN applications run on Unix/Linux, Mac OS X and Microsoft Windows. PMID:18541330

  9. "I am a trained nurse": the nursing identity of anarchist and radical Emma Goldman.

    Science.gov (United States)

    Connolly, Cynthia Anne

    2010-01-01

    For more than a century, scholars have analyzed the many dimensions of Emma Goldman. Remembered as an agent of revolution, feminism, sexual freedom, anarchy, and atheism, Goldman's motives, personality, and actions have generated an entire subgenre of historical scholarship. But although Goldman practiced nursing in New York City for ten years, one facet of her life that has been neglected is her nursing identity. Goldman's autobiography, Living My Life, reveals the way her nursing experiences informed her evolving anarchist political philosophy and international activism. She valued nursing for many reasons--for the economic independence it offered, identity it provided, and sense of community and connectivity she believed it encouraged. Finally, for Goldman, nursing represented was a vehicle to understand people's struggles and as a way of translating political philosophy into meaningful, practical solutions. PMID:20067092

  10. Marvin: A Heuristic Search Planner with Online Macro-Action Learning

    CERN Document Server

    Coles, A I; 10.1613/jair.2077

    2011-01-01

    This paper describes Marvin, a planner that competed in the Fourth International Planning Competition (IPC 4). Marvin uses action-sequence-memoisation techniques to generate macro-actions, which are then used during search for a solution plan. We provide an overview of its architecture and search behaviour, detailing the algorithms used. We also empirically demonstrate the effectiveness of its features in various planning domains; in particular, the effects on performance due to the use of macro-actions, the novel features of its search behaviour, and the native support of ADL and Derived Predicates.

    Baujard, O; Baujard, V; Aurel, S; Boyer, C; Appel, R D

    1998-01-01

    The World-Wide Web is an unstructured, multimedia and multilingual information network. While most efforts have addressed the structuring issue, very few attempts have been proposed to provide support for multilingual information retrieval. Yet, medical information is now available all over the world. The MARVIN (Multi-Agent Retrieval Vagabond on Information Network) softbot and its associated medical search engine MedHunt (Medical Hunter) are a solution for helping people, who only understand a few languages, to access multilingual information.

    1985-01-01

    Although cognitive AI is not generally viewed as being "scientific" in the same, strong sense as is physics, it shares a number of the properties of the natural sciences, especially biology. Certain of special themes of biology, notably the principles of historicity and of structure-function relations, are applicable in AI research. From a biologist's viewpoint, certain principles of cognitive AI research emerge.

    The making of oxygen from resources in the Martian atmosphere, known as In Situ Resource Utilization (ISRU), has the potential to provide substantial benefits for future robotic and human exploration. In particular, the ability to produce oxygen on Mars for use in propulsion, life support, and power systems can provide significant mission benefits such as a reducing launch mass, lander size, and mission and crew risk. To advance ISRU for possible incorporation into future human missions to Mars, NASA proposed including an ISRU instrument on the Mars 2020 rover mission, through an announcement of opportunity (AO). The purpose of the the Mars Atmosphere Resource Verification INsitu or (MARVIN) instrument is to provide the first demonstration on Mars of oxygen production from acquired and stored Martian atmospheric carbon dioxide, as well as take measurements of atmospheric pressure and temperature, and of suspended dust particle sizes and amounts entrained in collected atmosphere gases at different times of the Mars day and year. The hardware performance and environmental data obtained will be critical for future ISRU systems that will reduce the mass of propellants and other consumables launched from Earth for robotic and human exploration, for better understanding of Mars dust and mitigation techniques to improve crew safety, and to help further define Mars global circulation models and better understand the regional atmospheric dynamics on Mars. The technologies selected for MARVIN are also scalable for future robotic sample return and human missions to Mars using ISRU.

  6. Jean Rostand, an anti-nuclear biologist

    International Nuclear Information System (INIS)

    In the 70's, some scientists, like the French biologist Jean Rostand, were already militating in favour of solar-derived energy sources. One of his favored domain of thoughts was the one of relations between science, ethics and politics. Jean Rostand did not limit his writing work to biology but looked into the moral and political impacts of discoveries in the other scientific domains as well. From the 50's and during several years onward, he got strongly and deeply involved in a radical fight against the 'French atomic bomb'. He particularly stressed on the fact that 'the later we react, the harder will be the energy transition'. This book brings together his texts and conference talks against nuclear weapons and civil nuclear energy. From this compilation of documents, the author notices that, thirty five years later, these documents remain as topical as in the past, and that no energy reconversion has been undertaken by none of the successive French governments who remained under the double control of the petroleum and nuclear industry lobbies. This policy has led to limit the development of energy conservation and renewable energy sources and to increase the lateness of France in this domain with respect to other European countries

  7. Options Traders Reacting to Bad News: The SEC versus Goldman Sachs

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available This paper examines a specific case to shed light on the issue of how people trade during times of crisis, with specific focus on the options market and various options trading strategies. On April 16th 2010 the SEC announced charges against Goldman, Sachs & Co. for alleged fraudulent dealings, causing a significant share price decline. I examine the choices that options traders made in response to this market event, in terms of both choice of strategy (such as long call, straddle etc. and choice of option (maturity and strike price chosen. Volume in Puts spiked immediately, and evidence suggests that such trading was highly profitable for at least 30 minutes following the announcement. Traders also implemented volatility trades in the options market, although evidence suggests that they lost money on this activity. Trading in the weeks following the SEC announcement indicates that strong positive stock returns prompted increased trading in both Calls and Puts, while spikes in implied volatility discouraged such trading. Surprisingly, volume in volatility trades was not significantly affected by changes in implied volatility.

  9. The Society of Brains: How Alan Turing and Marvin Minsky Were Both Right

    Science.gov (United States)

    Struzik, Zbigniew R.

    2015-04-01

    In his well-known prediction, Alan Turing stated that computer intelligence would surpass human intelligence by the year 2000. Although the Turing Test, as it became known, was devised to be played by one human against one computer, this is not a fair setup. Every human is a part of a social network, and a fairer comparison would be a contest between one human at the console and a network of computers behind the console. Around the year 2000, the number of web pages on the WWW overtook the number of neurons in the human brain. But these websites would be of little use without the ability to search for knowledge. By the year 2000 Google Inc. had become the search engine of choice, and the WWW became an intelligent entity. This was not without good reason. The basis for the search engine was the analysis of the ’network of knowledge’. The PageRank algorithm, linking information on the web according to the hierarchy of ‘link popularity’, continues to provide the basis for all of Google's web search tools. While PageRank was developed by Larry Page and Sergey Brin in 1996 as part of a research project about a new kind of search engine, PageRank is in its essence the key to representing and using static knowledge in an emergent intelligent system. Here I argue that Alan Turing was right, as hybrid human-computer internet machines have already surpassed our individual intelligence - this was done around the year 2000 by the Internet - the socially-minded, human-computer hybrid Homo computabilis-socialis. Ironically, the Internet's intelligence also emerged to a large extent from ‘exploiting’ humans - the key to the emergence of machine intelligence has been discussed by Marvin Minsky in his work on the foundations of intelligence through interacting agents’ knowledge. As a consequence, a decade and a half decade into the 21st century, we appear to be much better equipped to tackle the problem of the social origins of humanity - in particular thanks to the

    Electronic data resources can enable molecular biologists to query and display many useful features that make benchwork more efficient and drive new discoveries. The UCSC Genome Browser provides a wealth of data and tools that advance one’s understanding of genomic context for many species, enable detailed understanding of data, and provide the ability to interrogate regions of interest. Researchers can also supplement the standard display with their own data to query and share with others. Effective use of these resources has become crucial to biological research today, and this unit describes some practical applications of the UCSC Genome Browser. PMID:19816931

    2016-05-01

    High-throughput genomic and proteomic studies have generated near-comprehensive catalogs of biological constituents within many model systems. Nevertheless, static catalogs are often insufficient to fully describe the dynamic processes that drive biology. Quantitative proteomic techniques address this need by providing insight into closely related biological states such as the stages of a therapeutic response or cellular differentiation. The maturation of quantitative proteomics in recent years has brought about a variety of technologies, each with their own strengths and weaknesses. It can be difficult for those unfamiliar with this evolving landscape to match the experiment at hand with the best tool for the job. Here, we outline quantitative methods for proteomic mass spectrometry and discuss their benefits and weaknesses from the perspective of the biologist aiming to generate meaningful data and address mechanistic questions.

  17. Comparison of ejection fraction and Goldman risk factor analysis to dipyridamole-thallium 201 studies in the evaluation of cardiac morbidity after aortic aneurysm surgery

    International Nuclear Information System (INIS)

    Associated coronary artery disease is the critical factor that influences early and late mortality after abdominal aortic aneurysm surgery. Dipyridamole-thallium 201 scintigraphy, left ventricular ejection fraction, and Goldman risk factor analysis have been suggested as preoperative noninvasive screening methods to detect significant coronary artery disease. In this series of 95 elective abdominal aortic aneurysm repairs dipyridamole-thallium 201 scintigraphy was highly predictive of the absence of perioperative cardiac morbidity (96% specificity, 44/46 normal scans, no cardiac morbidity), whereas ejection fraction (73% specificity, 31/42 normal ejection fraction, no cardiac morbidity) and Goldman risk factor analysis (84% specificity, 44/51 class I, no cardiac morbidity) were less. Furthermore, thallium redistribution on dipyridamole-thallium 201 scintigraphy leading to coronary angiography identified a significant number of patients with occult coronary artery disease who required preoperative coronary revascularization (8%, 8/95) and might have remained undetected on the basis of left ventricular ejection fraction or Goldman risk factor analysis. Finally, fixed thallium deficit, which some investigators have interpreted as a low probability finding for cardiac morbidity, was associated with a higher than expected incidence of cardiac complications. Forty-six percent (7/15) of all postoperative cardiac complications (three myocardial infarctions, three ischemic events, one death) occurred in patients with abdominal aortic aneurysms with fixed deficits. This suggests that patients with fixed deficits on dipyridamole-thallium 201 scintigraphy should be considered for later delayed (4 hours) thallium images or coronary angiography or both

    Political correctness urges us to state how wonderful it is to work with biologists and how, just as the lion will someday lie down with the lamb, so will interdisciplinary work, where biologists and physicists are mixed together in light, airy buildings designed to force socialization, give rise to wonderful new science. But it has been said that the only drive in human nature stronger than the sex drive is the drive to censor and suppress, and so I claim that it is OK for physicists and biologists to maintain a wary distance from each other, so that neither one censors or suppresses the wild ideas of the other.

  3. Educational background and professional participation by federal wildlife biologists: Implications for science, management, and The Wildlife Society

    Science.gov (United States)

    Schmutz, J.A.

    2002-01-01

    Over 2,000 people are employed in wildlife biology in the United States federal government. The size of this constituency motivated me to examine the amount of formal education federal biologists have received and the extent of continuing education they undertake by reading journals or attending scientific meetings. Most federal biologists who are members of The Wildlife Society (TWS) have a graduate degree. However, one-third have only a Bachelor of Science degree, despite the current trend toward hiring people with graduate degrees. Most federal biologists are not research biologists. Numbers of journals subscribed to was positively related to educational level. Less than one-third of all wildlife biologists employed by the United States Fish and Wildlife Service are members of TWS or subscribe to any of its journals. In contrast, the majority of presenters at the TWS 2000 Annual Conference were research biologists and members of TWS. The failure of many federal wildlife biologists to read scientific literature or attend professional meetings indicates a failure to promote the importance of continuing education in the federal workplace. I identify 2 potential adverse impacts of this failing: an inability to recognize important and relevant scientific contributions and an ineffectiveness in carrying out adaptive management.

  4. Fighting for life: Religion and science in the work of fish and wildlife biologists

    Science.gov (United States)

    Geffen, Joel Phillip

    Philosophers, historians, and sociologists of science have argued that it is impossible to separate fact from value. Even so, Americans generally demand that scientists be "objective." No bias is permitted in their work. Religious motivations in particular are widely considered anathema within the halls of science. My dissertation addresses both theoretical and practical aspects concerning objectivity in science through an examination of fish and wildlife biologists. I hypothesized that they use the language of objective science as a tool to convince others to protect habitats and species. Further, I claimed that this "rhetoric of science" is employed either consciously or unconsciously on behalf of personal values, and that religious and/or spiritual values figure significantly among these. Regarding the issue's practical applications, I argued in support of Susan Longino's assertion that while subjective influences exist in science, they do not necessarily indicate that objectivity has been sacrificed. My primary methodology is ethnographic. Thirty-five biologists working in the Pacific Northwest were interviewed during the course of summer 2001. Participant ages ranged from 23 to 78. Both genders were represented, as were various ethnic and cultural backgrounds, including Native American. I used a questionnaire to guide respondents through a consistent set of open-ended queries. I organized their answers under four categories: the true, the good, the beautiful, and the holy. The first three were borrowed from the theoretical writings of philosopher Immanuel Kant. The last came from Rudolf Otto's theological work. These categories provided an excellent analytical framework. I found that the great majority of fish and wildlife biologists strive for objectivity. However, they are also informed by powerful contextual values. These are derived from environmental ethics, aesthetic preferences pertaining to ecosystem appearance and function, and visceral experiences of

    Next generation sequencing (NGS) technologies have gained considerable popularity among biologists. For example, RNA-seq, which provides both genomic and functional information, has been widely used by recent functional and evolutionary studies, especially in non-model organisms. However, storing and transmitting these large data sets (primarily in FASTQ format) have become genuine challenges, especially for biologists with little informatics experience. Data compression is thus a necessity. KIC, a FASTQ compressor based on a new integer-mapped k-mer indexing method, was developed (available at http://www.ysunlab.org/kic.jsp). It offers high compression ratio on sequence data, outstanding user-friendliness with graphic user interfaces, and proven reliability. Evaluated on multiple large RNA-seq data sets from both human and plants, it was found that the compression ratio of KIC had exceeded all major generic compressors, and was comparable to those of the latest dedicated compressors. KIC enables researchers with minimal informatics training to take advantage of the latest sequence compression technologies, easily manage large FASTQ data sets, and reduce storage and transmission cost.

    The growth of world population, limitation of resources, economic problems and environmental issues force engineers to develop increasingly efficient solutions for logistic systems. Pure optimization for efficiency, however, has often led to technical solutions that are vulnerable to variations in supply and demand, and to perturbations. In contrast, nature already provides a large variety of efficient, flexible and robust logistic solutions. Can we utilize biological principles to design systems, which can flexibly adapt to hardly predictable, fluctuating conditions? We propose a bio-inspired "BioLogistics" approach to deduce dynamic organization processes and principles of adaptive self-control from biological systems, and to transfer them to man-made logistics (including nanologistics), using principles of modularity, self-assembly, self-organization, and decentralized coordination. Conversely, logistic models can help revealing the logic of biological processes at the systems level.

    2012-12-01

    Required by an increasing amount of scientists, the in silico docking field is in full expansion, new algorithms and methods appearing at an exponential rate. The sheer range of available programs is overwhelming for the bench-working biologist, which is often discouraging by the lack of a graphical user interface, good user manual or literature to validate a given program. This mini-review attempts to present the docking problem and available solutions from a non-bioinformatician point of view and makes a selection of the available servers and programs. These tools are evaluated from several points of view, as numbers of citations, ease of usage and computer requirements. Finally, the capabilities and limitations as well as specific applications of in silico docking techniques are presented.

    2005-02-01

    Full Text Available Abstract Background Collecting and managing information is a challenging task in a genome-wide profiling research project. Most databases and online computational tools require a direct human involvement. Information and computational results are presented in various multimedia formats (e.g., text, image, PDF, word files, etc., many of which cannot be automatically processed by computers in biologically meaningful ways. In addition, the quality of computational results is far from perfect and requires nontrivial manual examination. The timely selection, integration and interpretation of heterogeneous biological information still heavily rely on the sensibility of biologists. Biologists often feel overwhelmed by the huge amount of and the great diversity of distributed heterogeneous biological information. Description We developed an information management application called GeneNotes. GeneNotes is the first application that allows users to collect and manage multimedia biological information about genes/ESTs. GeneNotes provides an integrated environment for users to surf the Internet, collect notes for genes/ESTs, and retrieve notes. GeneNotes is supported by a server that integrates gene annotations from many major databases (e.g., HGNC, MGI, etc.. GeneNotes uses the integrated gene annotations to (a identify genes given various types of gene IDs (e.g., RefSeq ID, GenBank ID, etc., and (b provide quick views of genes. GeneNotes is free for academic usage. The program and the tutorials are available at: http://bayes.fas.harvard.edu/genenotes/. Conclusions GeneNotes provides a novel human-computer interface to assist researchers to collect and manage biological information. It also provides a platform for studying how users behave when they manipulate biological information. The results of such study can lead to innovation of more intelligent human-computer interfaces that greatly shorten the cycle of biology research.

  10. From glass flowers to computer games: Examining the emergent media practices of plant biologists

    Science.gov (United States)

    Reitmeyer, Morgan

    The goal of this project is to begin investigating the emergent media practices of current academic disciplines. This dissertation posits that Writing Across the Curriculum (WAC) scholars have investigated new media use in undergraduate pedagogy, and to some extent the practices of graduate students. However, WAC scholars have yet to try to understand how Writing in the Disciplines (WID) is being impacted by emergent media. The gap might be, in part, accounted for by the complexity of researching disciplinary writing compounded by the complexity of researching new media. However, in order to both design effective undergraduate curriculum and partner with peers across the discipline, this research must take place. This dissertation proposes a mixed method process, consisting of textual analysis, interviews and observations, in order to understand emergent media writing in the disciplines. Specifically, this research focuses on the practices of plant biologists online publication, online professionalization, and changing use of databases. This preliminary study reflects on the research practices that could be used to gather this information, as well what rhetoric and composition scholars have to gain from this type of difficult work.

  11. Conscience dilemma: to become a bioengineer or to survive as a biologist.

    Science.gov (United States)

    Selimoglu, Sureyya Mert

    2014-01-01

    Bioengineering is the consideration of biological problems from modern engineering, therefore money-oriented, perspective. Today, grant-giving bodies always favor bioengineering projects rather than pure biology projects (like those in ecology, entomology, etc.). Therefore, today's biologist is forced to be on the horns of a dilemma. They have to either submit a very powerful and valid reason for the proposal of their project, or change the project to one having a potential of money-based outcome. On the other hand, because of dealing with the living components of nature, conducting a research in pure biology is like a kind of worship. For this reason, from a believer scientist's view, a deviation (in terms of research) from biology to bioengineering can be considered like committing a sin. Unfortunately, today's wild capitalism has been bringing new sinners day by day, and this system will continue for the foreseeable future unless grant-giving bodies comprehend the real importance of pure biology.

  12. Cognitive empathy in inter-disciplinary research: the contrasting attitudes of plant breeders and molecular biologists towards rice

    2000-12-01

    I draw attention to the perceptions of and interactions between molecular biologists and scientists engaged in plant breeding in India, who have been attempting to employ molecular biology tools to understand and intervene to improve the rice crop. The present essay suggests that the concept of cognitive empathy is crucial for enabling basic scientists and applied scientists to begin to understand phenomena from the point of view of the other and from the point of view of society at large, and in arriving at solutions that are scientifically feasible and socially acceptable. Socialization into disciplinary cultures, organizational factors and individual anxieties seem to inhibit inter-disciplinary collaboration. The majority of rice breeders and a small group of molecular biologists emphasize the relative merits of marker-assisted selection (MAS) in the near term vis-à-vis the currently controversial transgenic approach for rice crop improvement in India.

    Full Text Available Abstract Background This study presents an empirical investigation of the ethical reasoning and ethical issues at stake in the daily work of physicians and molecular biologists in Denmark. The aim of this study was to test empirically whether there is a difference in ethical considerations and principles between Danish physicians and Danish molecular biologists, and whether the bioethical principles of the American bioethicists Tom L. Beauchamp and James F. Childress are applicable to these groups. Method This study is based on 12 semi-structured interviews with three groups of respondents: a group of oncology physicians working in a clinic at a public hospital and two groups of molecular biologists conducting basic research, one group employed at a public university and the other in a private biopharmaceutical company. Results In this sample, the authors found that oncology physicians and molecular biologists employed in a private biopharmaceutical company have the specific principle of beneficence in mind in their daily work. Both groups are motivated to help sick patients. According to the study, molecular biologists explicitly consider nonmaleficence in relation to the environment, the researchers' own health, and animal models; and only implicitly in relation to patients or human subjects. In contrast, considerations of nonmaleficence by oncology physicians relate to patients or human subjects. Physicians and molecular biologists both consider the principle of respect for autonomy as a negative obligation in the sense that informed consent of patients should be respected. However, in contrast to molecular biologists, physicians experience the principle of respect for autonomy as a positive obligation as the physician, in dialogue with the patient, offers a medical prognosis based upon the patients wishes and ideas, mutual understanding, and respect. Finally, this study discloses utilitarian characteristics in the overall conception of

    Investigations of living organisms have led biologists and physicians to introduce fundamental concepts, including Brownian motion, the First Law of Thermodynamics, Poiseuille's Law of fluid flow, and Fick's Law of diffusion into physics. Given the prominence of viscous forces within and around cells and the experience of identifying and quantifying such resistive forces, biophysical cell biologists have an unique perspective in discovering the viscous forces that cause moving particles to respond to an applied force in a nonlinear manner. Using my experience as a biophysical cell biologist, I show that in any space consisting of a photon gas with a temperature above absolute zero, Doppler-shifted photons exert a velocity-dependent viscous force on moving charged particles. This viscous force prevents charged particles from exceeding the speed of light. Consequently, light itself prevents charged particles from moving faster than the speed of light. This interpretation provides a testable alternative to the i...

    Full Text Available Objective. We here describe the development of a freely available online database resource, GeneSpeed Beta Cell, which has been created for the pancreatic islet and pancreatic developmental biology investigator community. Research Design and Methods. We have developed GeneSpeed Beta Cell as a separate component of the GeneSpeed database, providing a genomics-type data repository of pancreas and islet-relevant datasets interlinked with the domain-oriented GeneSpeed database. Results. GeneSpeed Beta Cell allows the query of multiple published and unpublished select genomics datasets in a simultaneous fashion (multiexperiment viewing and is capable of defining intersection results from precomputed analysis of such datasets (multidimensional querying. Combined with the protein-domain categorization/assembly toolbox provided by the GeneSpeed database, the user is able to define spatial expression constraints of select gene lists in a relatively rigid fashion within the pancreatic expression space. We provide several demonstration case studies of relevance to islet cell biology and development of the pancreas that provide novel insight into islet biology. Conclusions. The combination of an exhaustive domain-based compilation of the transcriptome with gene array data of interest to the islet biologist affords novel methods for multidimensional querying between individual datasets in a rapid fashion, presently not available elsewhere.

    2015-08-01

    At the moment, the conditions are in place to describe how to construct nuclear pores and how they work, missing only real understanding of process. The DNA-RNA-protein paradigm proposed by Crick 53 years ago (Symp Soc Exp Biol 12:138-163, 1958; Nature 227:561-563, 1970) severely hampers our understanding of nuclear pore structure and assembly because the problem lies outside paradigm. DNA in this scheme only plays the role of information storage from which information is transferred to RNA, then from RNA to proteins after which proteins perform all of the functions in the cell. Although it is known that DNA is able to build nucleosomes in vivo, many in vitro structures types of origami (Rothemund, Nature 440:297-302, 2006), the DNA is considered to be exotic as structural material for cells. The structural role of RNA is difficult to ignore, in connections with their participation in structures of ribosomes, ribonucleoproteins, and ribozymes, but imagine that DNA performs an important structural role in the cell is impossible in opinion of many authors. So, when there was a problem in explaining the origin of the nuclear pore, all efforts of biologists were directed to proteins such as nucleoporins, especially when taking into account that there are 30 nucleoporins and only one DNA. Here, I try to explain the typical mistakes of the old approach to such a complex problem as nuclear pore structure and assembly. PMID:25758231

  1. Environmental radiation effects. A need to question old paradigms and to enhance collaboration between radiation biologists and radiation ecologists

    International Nuclear Information System (INIS)

    The radiological sciences are a real enigma- the maturity and depth of understanding concerning human dosimetry contrasts sharply with our shallow understanding about radiological effects to biota. The richness of the radiological sciences is apparent by looking at the refinements made to the fundamental unit used in human dosimetry. The radiological sciences have developed to where probabilistic risk factors can now be applied that predict specific deleterious effects to humans per unit dose. And yet, these same radiological sciences that have made such advances in human dosimetry, are primitive when effects to biota are concerned. There are no specialized units, no agreed upon weighting factors, no factors that account for distributions within an organism's body, and certainly no risk factors. There are no internationally agreed upon criteria or policies that explicitly address protection of the environment from ionizing radiation. There is not even agreement as to what endpoint should be measured to quantify an environmental effect. The bold aspect of the ICRP framework is the inclusion of sub-lethal effects (reduced reproductive success, scorable DNA damage) as endpoints. A major research consortium funded by the European Union, is also recommending that cytogenetic damage be used as an effect endpoint. The inclusion of sub-lethal endpoints begs for a linkage between molecular effects and those observed in individuals and populations. To do so, will require a strengthening of what has traditionally been separated disciplines of radiation biology and radiation ecology. The impacts of phenomena studied in the petri dishes of radiation biologists (such as genomic instability, adaptive response, and bystander effects) need to be explored and correlated to effects observed in whole organisms and populations, in collaboration with radiation ecologists.

    Full Text Available The English term ‘early psychosis’ was coined in the 1930s to refer to feelings of irritability, loss of concentration, hypochondriac ideas, moodiness and lassitude that were seen to precede the onset of clear-cut hallucinations and delusions. The history of thinking about ‘early psychosis’ under names such as ‘latent’, ‘masked’, ‘mild’, ‘simple’ or ‘sluggish’ schizophrenia before World War II and afterwards on the different sides of the Wall and the Iron Curtain reveals ‘early psychosis’ as a mirror of quite aged international biologist controversies that are still alive today and to the same extent as they are misunderstood, are influential in their implications in today’s psychiatry.

    Full Text Available The function of a newly sequenced gene can be discovered by determining its sequence homology with known proteins. BLAST is the most extensively used sequence analysis program for sequence similarity search in large databases of sequences. With the advent of next generation sequencing technologies it has now become possible to study genes and their expression at a genome-wide scale through RNA-seq and metagenome sequencing experiments. Functional annotation of all the genes is done by sequence similarity search against multiple protein databases. This annotation task is computationally very intensive and can take days to obtain complete results. The program mpiBLAST, an open-source parallelization of BLAST that achieves superlinear speedup, can be used to accelerate large-scale annotation by using supercomputers and high performance computing (HPC clusters. Although many parallel bioinformatics applications using the Message Passing Interface (MPI are available in the public domain, researchers are reluctant to use them due to lack of expertise in the Linux command line and relevant programming experience. With these limitations, it becomes difficult for biologists to use mpiBLAST for accelerating annotation. No web interface is available in the open-source domain for mpiBLAST.

    Part 1 of this report focuses on results of the western Kentucky carbon storage test, and provides a basis for evaluating injection and storage of supercritical CO2 in Cambro-Ordovician carbonate reservoirs throughout the U.S. Midcontinent. This test demonstrated that the Cambro- Ordovician Knox Group, including the Beekmantown Dolomite, Gunter Sandstone, and Copper Ridge Dolomite in stratigraphic succession from shallowest to deepest, had reservoir properties suitable for supercritical CO2 storage in a deep saline reservoir hosted in carbonate rocks, and that strata with properties sufficient for long-term confinement of supercritical CO2 were present in the deep subsurface. Injection testing with brine and CO2 was completed in two phases. The first phase, a joint project by the Kentucky Geological Survey and the Western Kentucky Carbon Storage Foundation, drilled the Marvin Blan No. 1 carbon storage research well and tested the entire Knox Group section in the open borehole – including the Beekmantown Dolomite, Gunter Sandstone, and Copper Ridge Dolomite – at 1152–2255 m, below casing cemented at 1116 m. During Phase 1 injection testing, most of the 297 tonnes of supercritical CO2 was displaced into porous and permeable sections of the lowermost Beekmantown below 1463 m and Gunter. The wellbore was then temporarily abandoned with a retrievable bridge plug in casing at 1105 m and two downhole pressure-temperature monitoring gauges below the bridge plug pending subsequent testing. Pressure and temperature data were recorded every minute for slightly more than a year, providing a unique record of subsurface reservoir conditions in the Knox. In contrast, Phase 2 testing, this study, tested a mechanically-isolated dolomitic-sandstone interval in the Gunter.

    We have developed a set of laboratories and hands on activities to accompany a new two-semester interdisciplinary physics course that has been successfully developed and tested in two small test classes of students at the University of Maryland, College Park (UMD) in 2012-2013. We have designed the laboratories to be taken accompanying a reformed course in the student's second year, with calculus, biology, and chemistry as prerequisites. This permits the laboratories to include significant content on physics relevant to cellular scales, from chemical interactions to random motion and charge screening in fluids. We also introduce the students to research-grade equipment and modern physics analysis tools in contexts relevant to biology, while maintaining the pedagogically valuable open-ended laboratory structure of reformed laboratories. Preliminary student results from these two small test classes are discussed.

    2016-05-01

    A brief review of Dr. Hilda Cid, Chilean scientist who excelled in the field of crystallography, is presented. Dr. Cid was born in 1933 in Talcahuano, where she completed her primary and secondary education, graduating as a Teacher of mathematics and physics from the University of Chile in 1958. She continued graduate studies at MIT, USA, where obtained the PhD in 1964. Upon her return to Chile, she joined the Austral University in Valdivia, where she dedicated to characterize, by X-ray, biological material. During that time, she was actively involved in the social changes taking place in the university and in the country. Thus, following the bloody coup of 1973, she and her family were persecuted and forced to go into exile to Sweden. In the decade of the 1980 she returns to Chile, and settles at University of Concepción, where she teaches, conducts research and organizes a number of latino-american courses and symposiums. Knowing that Hilda Cid formed a real school, where her students -now distinguished professionals and researchers- cast their teachings through Chile and other countries, we ended the article with a reflection about why Hilda Cid, despite its obvious scientific achievements, remains ignored by most of the scientific establishment in Chile.

  16. Genetics of asthma: a molecular biologist perspective

    Directory of Open Access Journals (Sweden)

    Ghosh Balaram

    2009-05-01

    Full Text Available Abstract Asthma belongs to the category of classical allergic diseases which generally arise due to IgE mediated hypersensitivity to environmental triggers. Since its prevalence is very high in developed or urbanized societies it is also referred to as "disease of civilizations". Due to its increased prevalence among related individuals, it was understood quite long back that it is a genetic disorder. Well designed epidemiological studies reinforced these views. The advent of modern biological technology saw further refinements in our understanding of genetics of asthma and led to the realization that asthma is not a disorder with simple Mendelian mode of inheritance but a multifactorial disorder of the airways brought about by complex interaction between genetic and environmental factors. Current asthma research has witnessed evidences that are compelling researchers to redefine asthma altogether. Although no consensus exists among workers regarding its definition, it seems obvious that several pathologies, all affecting the airways, have been clubbed into one common category called asthma. Needless to say, genetic studies have led from the front in bringing about these transformations. Genomics, molecular biology, immunology and other interrelated disciplines have unearthed data that has changed the way we think about asthma now. In this review, we center our discussions on genetic basis of asthma; the molecular mechanisms involved in its pathogenesis. Taking cue from the existing data we would briefly ponder over the future directions that should improve our understanding of asthma pathogenesis.

    2009-07-01

    The University of Maryland Physics Education Research Group has done a five-year project to rethink, observe, and reform introductory algebra-based (college) physics, which primarily serves life-science majors. We refocused the class on helping the students learn to think scientifically—to build coherence, think in terms of mechanisms, and to follow the implications of assumptions. We designed the course to tap into students' productive conceptual and epistemological resources, based on a theoretical framework from research on learning. The reformed class retains its traditional structure in terms of time and instructional personnel, but we modified existing best-practices curricular materials. We provided class-controlled spaces for student collaboration, which allowed us to observe and record students learning directly. We also scanned all written homework and examinations and administered pre-post conceptual and epistemological surveys. The reformed class enhanced the strong gains on pre-post conceptual tests produced by the best-practices materials while obtaining unprecedented pre-post gains on epistemological surveys instead of the traditional losses.

  18. The biologist and the economist: is dialogue possible?

    Science.gov (United States)

    Keyfitz, N

    1992-06-01

    There is a need for demography to be brought into policy-making discussions. In the time of Malthus, both economists and ecologists spoke the same language and each group was receptive to and supportive of the ideas of the other. The present organization of academic life precludes interdisciplinary communication. Malthus saw the limit as food supply; today, technology seems to be the defining criteria, although access to world supplies is also unevenly distributed. Minerals were once thought to present limits, but again technology was able to generate replacements as the Green Revolution provided an option for expanding food supply. During the 1950s and 1960s, limits were perceived by Arthur Lewis, Coale, and Hoover to be in shortages of capital. Now capital is seen as a result of development and not a cause. The strongest argument for limiting population growth appears to be the stability of planetary support systems (species diversity, ozone layer, global climate, and others). Knowledge of these support systems is limited and it would be wise not to press the world's carrying capacity under such conditions. Ignorance of planetary support systems may mean that the circle may be tightening closer than we know, or that a sudden disaster is possible. It is a complex task to circumscribe boundaries to various essentials for human life. Regardless of whether there is a solution to various essentials for human life. Regardless of whether there is a solution to the known or unknown environmental problems, it is possible, easy, and reliable to reduce the population by having fewer births than deaths. Economists argue that the vagaries and uncertainties of environmental damage prevent taking environmental constraints into account, when uncertainties have always been with us. A real debate on the issues instead of disciplines talking past each other would occur if all facts and conclusions were accepted by all parties. The conclusion should be that population increases must be as small as possible with the widest distribution of family planning and the most convincing presentation of information. The assumption of all disciplines must be that limits are severe and permanent. A decade ago this was the policy. Scholars in the face of constituent ignorance and legislator's inaction must take responsibility for information creation and diffusion (classroom to media to word of mouth). Expenditure taxes need to replace income taxes. PMID:12178977

  19. Molecular biologists backing effort to map entire human genome

    International Nuclear Information System (INIS)

    This article discusses how the program to map and sequence the human genome will be managed. The National Research Council (NRC) recommends that a 15-year $200-million-a-year effort to map all human genes should begin immediately. However, some people have balked at the idea, saying it is a ploy to raise money. Part of the skeptic's uneasiness stems from the involvement of the Department of Energy (DOE), an agency not often linked with biological research. The DOE's interest arises from its commitment to understanding the biological effects of nuclear radiation. Critics say it is a budget-boosting tactic. This article explains some of the arguments for and against the project and explains exactly what it would involve

  11. International activities in environmental radiation protection - a radiation biologists perspective

    International Nuclear Information System (INIS)

    The evolving integration of environmental impact assessments into the regulatory process together with Society's concern about environmental protection have emphasised the importance of developing a common international approach that demonstrates protection of the environment from ionising radiation. ICRP has expressed their wish to play a key role, both in advising and in providing the basic interpretation of existing scientific knowledge for such an approach. The European Union launched a research project three years ago, aiming at developing a methodology to be used for environmental risk assessments for ionising radiation (Framework for ASSessment of Environmental impacT). The main objective of FASSET has been to produce a system for the environmental risk assessments which links together exposures, doses and effects. This is accomplished by use of reference organisms including radioecological and dosimetric modelling. Within FASSET a database on biological effects was also set up including more than thousand references and ca 25 000 data entries. Most of the information in the database, however, originates from studies on acute exposures while the focus for non-human organisms must be on chronic exposures to long-lived radionuclides in the environment. It therefore seems necessary to perform several extrapolation tasks in order to characterize the risks. The heterogeneity of exposure conditions in the environment along with non-uniform deliverance of doses of main practical relevance must be considered. This will have great impact on the final biological effects. Applications of weighting factors may be anticipated which are already an established method in radiation protection dosimetry. A summary of the work that has been completed to date in FASSET and ICRP will be presented. Some aspects will be further given on the RBE key issues

  16. Thousands of rab GTPases for the cell biologist.

    Directory of Open Access Journals (Sweden)

    Yoan Diekmann

    2011-10-01

    Full Text Available Rab proteins are small GTPases that act as essential regulators of vesicular trafficking. 44 subfamilies are known in humans, performing specific sets of functions at distinct subcellular localisations and tissues. Rab function is conserved even amongst distant orthologs. Hence, the annotation of Rabs yields functional predictions about the cell biology of trafficking. So far, annotating Rabs has been a laborious manual task not feasible for current and future genomic output of deep sequencing technologies. We developed, validated and benchmarked the Rabifier, an automated bioinformatic pipeline for the identification and classification of Rabs, which achieves up to 90% classification accuracy. We cataloged roughly 8.000 Rabs from 247 genomes covering the entire eukaryotic tree. The full Rab database and a web tool implementing the pipeline are publicly available at www.RabDB.org. For the first time, we describe and analyse the evolution of Rabs in a dataset covering the whole eukaryotic phylogeny. We found a highly dynamic family undergoing frequent taxon-specific expansions and losses. We dated the origin of human subfamilies using phylogenetic profiling, which enlarged the Rab repertoire of the Last Eukaryotic Common Ancestor with Rab14, 32 and RabL4. Furthermore, a detailed analysis of the Choanoflagellate Monosiga brevicollis Rab family pinpointed the changes that accompanied the emergence of Metazoan multicellularity, mainly an important expansion and specialisation of the secretory pathway. Lastly, we experimentally establish tissue specificity in expression of mouse Rabs and show that neo-functionalisation best explains the emergence of new human Rab subfamilies. With the Rabifier and RabDB, we provide tools that easily allows non-bioinformaticians to integrate thousands of Rabs in their analyses. RabDB is designed to enable the cell biology community to keep pace with the increasing number of fully-sequenced genomes and change the scale at which we perform comparative analysis in cell biology.

  18. Microbial proteomics: a mass spectrometry primer for biologists

    Directory of Open Access Journals (Sweden)

    Graham Ciaren

    2007-08-01

    Full Text Available Abstract It is now more than 10 years since the publication of the first microbial genome sequence and science is now moving towards a post genomic era with transcriptomics and proteomics offering insights into cellular processes and function. The ability to assess the entire protein network of a cell at a given spatial or temporal point will have a profound effect upon microbial science as the function of proteins is inextricably linked to phenotype. Whilst such a situation is still beyond current technologies rapid advances in mass spectrometry, bioinformatics and protein separation technologies have produced a step change in our current proteomic capabilities. Subsequently a small, but steadily growing, number of groups are taking advantage of this cutting edge technology to discover more about the physiology and metabolism of microorganisms. From this research it will be possible to move towards a systems biology understanding of a microorganism. Where upon researchers can build a comprehensive cellular map for each microorganism that links an accurately annotated genome sequence to gene expression data, at a transcriptomic and proteomic level. In order for microbiologists to embrace the potential that proteomics offers, an understanding of a variety of analytical tools is required. The aim of this review is to provide a basic overview of mass spectrometry (MS and its application to protein identification. In addition we will describe how the protein complexity of microbial samples can be reduced by gel-based and gel-free methodologies prior to analysis by MS. Finally in order to illustrate the power of microbial proteomics a case study of its current application within the Bacilliaceae is given together with a description of the emerging discipline of metaproteomics.

    2009-01-01

    From the structures of isolated protein complexes to the molecular dynamics of whole cells, neutron methods can achieve a resolution in complex systems that is inaccessible to other techniques. Biology is fortunate in that it is rich in water and hydrogen, and this allows us to exploit the differential sensitivity of neutrons to this element and its major isotope, deuterium. Furthermore, neutrons exhibit wave properties that allow us to use them in similar ways to light, X-rays and electrons....

  7. Game on, science - how video game technology may help biologists tackle visualization challenges.

    Directory of Open Access Journals (Sweden)

    Zhihan Lv

    Full Text Available The video games industry develops ever more advanced technologies to improve rendering, image quality, ergonomics and user experience of their creations providing very simple to use tools to design new games. In the molecular sciences, only a small number of experts with specialized know-how are able to design interactive visualization applications, typically static computer programs that cannot easily be modified. Are there lessons to be learned from video games? Could their technology help us explore new molecular graphics ideas and render graphics developments accessible to non-specialists? This approach points to an extension of open computer programs, not only providing access to the source code, but also delivering an easily modifiable and extensible scientific research tool. In this work, we will explore these questions using the Unity3D game engine to develop and prototype a biological network and molecular visualization application for subsequent use in research or education. We have compared several routines to represent spheres and links between them, using either built-in Unity3D features or our own implementation. These developments resulted in a stand-alone viewer capable of displaying molecular structures, surfaces, animated electrostatic field lines and biological networks with powerful, artistic and illustrative rendering methods. We consider this work as a proof of principle demonstrating that the functionalities of classical viewers and more advanced novel features could be implemented in substantially less time and with less development effort. Our prototype is easily modifiable and extensible and may serve others as starting point and platform for their developments. A webserver example, standalone versions for MacOS X, Linux and Windows, source code, screen shots, videos and documentation are available at the address: http://unitymol.sourceforge.net/.

    2015-01-01

    Non-VKA oral anticoagulants (NOACs), thanks to their ease of use and their similar or superior safety/efficacy profiles versus warfarin, have now widely reached the lucrative market of anticoagulation. However, while the marketing authorization holders always claim, in a quite unclear way that no monitoring is required, accumulative evidence and cases of major bleeding have been described in the literature and reported by spontaneous reporting systems at the regulator's level. These compounds are usually given at fixed doses without routine coagulation monitoring. However, new data suggests that an assessment of the response at the individual level could improve the benefit-risk ratio of, at least dabigatran. Therefore, in certain patient populations, i.e. acute or chronic renal impairment or multiple drug interactions, measurement of drug exposure may be useful to ensure an optimal treatment response. More specific circumstances such as patients experiencing a haemorrhagic or thromboembolic event during the treatment duration, patients who require urgent surgery or an invasive procedure, or patient with a suspected overdose could benefit from such a measurement. This article aims at providing guidance on how to best estimate the intensity of anticoagulation using laboratory assays in daily practice. PMID:25857818

    Full Text Available The advent and adoption of Web 2.0 technologies offers a powerful approach to enhancing the capture of information in natural resource ecology, notably community knowledge of species distributions. Such information has previously been collected using, for example, postal surveys; these are typically inefficient, with low response rates, high costs, and requiring respondents to be spatially literate. Here we describe an example, using the Google Maps Application Programming Interface, to discuss the opportunities such tools provide to conservation biology. Toad Tracker was created as a prototype to demonstrate the utility of this technology to document the distribution of an invasive vertebrate pest species, the cane toad, within Australia. While the technological aspects of this tool are satisfactory, manager resistance towards its use raises issues around the public nature of the technology, the collaborative (non-expert role in data collection, and data ownership. We conclude in suggesting that, for such tools to be accepted by non-innovation adopters, work is required on both the technological aspects and, importantly, a cultural change is required to create an environment of acceptance of the shifting relationship between authority, expertise and knowledge.

  2. Meet the biologists: Sour gas treatment uses biology rather than chemistry to clean things up

    Energy Technology Data Exchange (ETDEWEB)

    Budd, G.

    2003-03-01

    Basic elements of the new bio-desulfurization technology are described. The new process uses the commonly occurring bacterium, Thiobacillus, rather than chemical means to remove hydrogen sulfide from natural gas. Development of the process began some ten years ago in the Netherlands as a means to clean sewage water and purify water for beer. The application of removing hydrogen sulfide from natural gas evolved upon discovery that the process was able to convert hydrogen sulfide to sulfur. Key to the bio-desulfurization process is the Thiobacillus bacterium, which unlike other plant forms, relies on chemosynthesis (instead of photosynthesis) of hydrogen sulfide, oxygen and carbon dioxide for its energy requirements. The technology has applications in refineries as well as in gas processing plants. It is well suited for use in Canada where operations tend to be on the small scale (less than 50 tonnes per day). The portable unit can be moved to another location when production at a given well drops off.

  5. Microfluidics made easy: A robust low-cost constant pressure flow controller for engineers and cell biologists.

    Science.gov (United States)

    Mavrogiannis, Nicholas; Ibo, Markela; Fu, Xiaotong; Crivellari, Francesca; Gagnon, Zachary

    2016-05-01

    Over the last decade, microfluidics has become increasingly popular in biology and bioengineering. While lab-on-a-chip fabrication costs have continued to decrease, the hardware required for delivering controllable fluid flows to the microfluidic devices themselves remains expensive and often cost prohibitive for researchers interested in starting a microfluidics project. Typically, microfluidic experiments require precise and tunable flow rates from a system that is simple to operate. While many labs use commercial platforms or syringe pumps, these solutions can cost thousands of dollars and can be cost prohibitive. Here, we present an inexpensive and easy-to-use constant pressure system for delivering flows to microfluidic devices. The controller costs less than half the price of a single syringe pump but can independently switch and deliver fluid through up to four separate fluidic inlets at known flow rates with significantly faster fluid response times. It is constructed of readily available pressure regulators, gauges, plastic connectors and adapters, and tubing. Flow rate is easily predicted and calibrated using hydraulic circuit analysis and capillary tubing resistors. Finally, we demonstrate the capabilities of the flow system by performing well-known microfluidic experiments for chemical gradient generation and emulsion droplet production. PMID:27279931

The article adds to microbiological uses of the historical record by putting observations of animals with influenza in historical contexts, in particular the context of military dealings with influenza at the end of the First World War, and the social position of veterinary medicine. The case of the Dutch military horse veterinarian Emile Bemelmans, who argued that human and horse influenza were identical, illustrates that knowledge of these contexts is important to critically use historical sources reporting animals with influenza in present-day biological influenza research.

    Full Text Available Complications of Coronary artery disease remain the most common cause of morbidity and mortality after vascular surgical procedures. Goldman risk factor analysis has been suggested as peri-operative noninvasive screening method to detect significant coronary artery disease in emergent vascular procedures."nMethods and Materials: In this study, the accuracy of the Goldman scale was assessed with regard to the development of cardiac complications such as asymptomatic ischemic change in ECG, arrhythmia, myocardial infarction and cardiac death. We studied 100 patients that were required emergent vascular procedures from 2000-2001. Data about perioperative complications were extracted and analyzed using SPSS computer program."nResults: Our study indicated there is not statistical correlation between cardiac death, infarction, arrythmia, ECG change, age, sex and cardiac class."nConclusion: We concluded that Goldman scale could not be regarded as a screening method to predict peri-operative cardiac complications in emergent vascular procedures.

    1998-01-01

    World-Wide Web is a media where information is unstructured, distributed, multimedia and multilingual. Many tools have been developed to help users search for information: subject hierarchies, general search engines, browsers and search assistants. Although helpful, they show serious limitations, mainly in terms of precision, multilingual indexing and distribution. The M.A.R.V.I.N. project (Multi Agent Retrieval Vagabond on Information Networks) proposes solutions with a distribution of the indexing task in agents specialized in a given domain. M.A.R.V.I.N. has been successfully applied to the medical domain. The medical index and its associated search engine MedHunt (Medical Hunter) demonstrate the interest of such an approach with currently 50,000 indexed medical sites and more than 100,000 accesses each month.

Many of the favorable and unfavorable conditions are nearly the same. It seems reasonable for the Goldman & Sachs to put the four countries together and coin a new word. But obviously Goldman & Sachs Co. regards the BRICs as a new group in the international arena; it is also true for the West media and some analysts in particular. Next, let us discuss whether Brazil, Russia, India and China could form a group, or is it possible for them to form an international political and economic group that takes concerted action?

    In the 1930s, Gilberto Freyre's praise of mixed-race people in Brazil challenged the idea of white supremacy, contributing to the building of a new Brazilian identity. In the 1950s, Freyre projected the idea of openness and racial mixture onto the Portuguese empire, fuelling Salazar's colonial propaganda. The idea of Lusotropicalism was contested by Marvin Harris and Charles Boxer, who demonstrated that there were very few mixed-race people in Angola and Mozambique, and exposed the long histo...

  11. Experimental constraints on anti-gravity and antimatter, in the context of dark energy

    CERN Document Server

    Ting, Yuan-Sen

    2013-01-01

    In a paper by Villata (2011), the possibility of a repulsive gravitational interaction between antimatter and ordinary matter was discussed. The author argued that this anti-gravity can be regarded as a prediction of general relativity, under the assumption of CPT symmetry. Stringent experimental constraints have been established against such a suggestion. The measurement of free-fall accelerations of various nuclei by the Eot-Wash group and searches for equivalence principle violation through the gravitational splitting in kaon physics consistently establish null results on any difference between the gravitational behaviour of antimatter and ordinary matter. The original arguments against antigravity were questioned by Nieto & Goldman (1991). In the light of new experiments as well as theoretical developments in the past 20 years, some of Nieto & Goldman's concerns have been addressed. While a precise measurement of the free-fall acceleration of antihydrogen will eventually lay this issue to rest, th...

    2012-01-01

    A Goldman Sachs study (2008) estimates that between 60 and 80 million people are introduced to the consumer market of durable goods annually, forming a kind of new worldwide middle class. The environmental impacts of these new consumers are not insignificant, and motivate important international negotiations regarding limits to greenhouse gas (GHG) emissions. This is a matter of concern even if the technological innovations aimed at the ?decarbonisation? of economies advance faster in the fut...

  16. A generalisation of the Buchdahl transformation and perfect fluid solutions

    International Nuclear Information System (INIS)

    Perfect fluid solutions in general relativity are examined. The pressure isotropy relation possesses a discrete symmetry in the derivatives of the metric functions. It is shown that a generalisation of Buchdahl's original transformation (Aust. J. Phys.; 9: 13 (1956)) allows new physically reasonable solutions to be obtained from known solutions. An example is given. Previously noticed first by Buchdahl, and later by Glass and Goldman (J. Math. Phys.; 19: 856 (1978)), this symmetry was thought to lead only to unphysical solutions. (author)

    Mughal, Tariq I; Radich, Jerald P; Deininger, Michael W; Apperley, Jane F; Hughes, Timothy P; Harrison, Christine J; Gambacorti-Passerini, Carlo; Saglio, Giuseppe; Cortes, Jorge; Daley, George Q

    2016-05-01

    With the deaths of Janet Rowley and John Goldman in December 2013, the world lost two pioneers in the field of chronic myeloid leukemia. In 1973, Janet Rowley, unraveled the cytogenetic anatomy of the Philadelphia chromosome, which subsequently led to the identification of the BCR-ABL1 fusion gene and its principal pathogenetic role in the development of chronic myeloid leukemia. This work was also of major importance to support the idea that cytogenetic changes were drivers of leukemogenesis. John Goldman originally made seminal contributions to the use of autologous and allogeneic stem cell transplantation from the late 1970s onwards. Then, in collaboration with Brian Druker, he led efforts to develop ABL1 tyrosine kinase inhibitors for the treatment of patients with chronic myeloid leukemia in the late 1990s. He also led the global efforts to develop and harmonize methodology for molecular monitoring, and was an indefatigable organizer of international conferences. These conferences brought together clinicians and scientists, and accelerated the adoption of new therapies. The abundance of praise, tributes and testimonies expressed by many serve to illustrate the indelible impressions these two passionate and affable scholars made on so many people's lives. This tribute provides an outline of the remarkable story of chronic myeloid leukemia, and in writing it, it is clear that the historical triumph of biomedical science over this leukemia cannot be considered without appreciating the work of both Janet Rowley and John Goldman.

  2. From Princesa to Princess with a Prince: 1994 and 2001 Fernanda's Stories

    Directory of Open Access Journals (Sweden)

    Polina Shvanyukova

    2012-12-01

    Full Text Available In an analysis of what presents itself as a cinematic transposition of a literary text, it is difficult to break away from the “binary oppositions [...] literature versus cinema, high culture versus mass culture, original versus copy" (James Naremore. In the case of Princesa (2001, directed by Henrique Goldman, it is questionable whether we can speak about an adaptation at all. As Goldman himself stated, he got the idea for making the film after reading the eponymous 1994 book written by Fernanda Farias de Albuquerque in collaboration with Maurizio Jannelli. In his film, Goldman has made drastic changes to the autobiographical story of Fernanda, the Brazilian transsexual prostitute who travels to Europe in order to earn money for her sex-change operation. However, the film was in fact dedicated to the memory of the real Fernanda, who had passed away in the meantime. In this contribution, the two works will be examined in their relationship to a third source-text by paying special attention to the processes of worldmaking as developed in Nelson Goodman's seminal 1978 book and expanded in the 2010 collection of essays Cultural Ways of Worldmaking.

  3. The thermodynamic dissociation constants of four non-steroidal anti-inflammatory drugs by the least-squares nonlinear regression of multiwavelength spectrophotometric pH-titration data.

    Science.gov (United States)

    Meloun, Milan; Bordovská, Sylva; Galla, Lubomír

    2007-11-30

    The mixed dissociation constants of four non-steroidal anti-inflammatory drugs (NSAIDs) ibuprofen, diclofenac sodium, flurbiprofen and ketoprofen at various ionic strengths I of range 0.003-0.155, and at temperatures of 25 degrees C and 37 degrees C, were determined with the use of two different multiwavelength and multivariate treatments of spectral data, SPECFIT/32 and SQUAD(84) nonlinear regression analyses and INDICES factor analysis. The factor analysis in the INDICES program predicts the correct number of components, and even the presence of minor ones, when the data quality is high and the instrumental error is known. The thermodynamic dissociation constant pK(a)(T) was estimated by nonlinear regression of (pK(a), I) data at 25 degrees C and 37 degrees C. Goodness-of-fit tests for various regression diagnostics enabled the reliability of the parameter estimates found to be proven. PALLAS, MARVIN, SPARC, ACD/pK(a) and Pharma Algorithms predict pK(a) being based on the structural formulae of drug compounds in agreement with the experimental value. The best agreement seems to be between the ACD/pK(a) program and experimentally found values and with SPARC. PALLAS and MARVIN predicted pK(a,pred) values with larger bias errors in comparison with the experimental value for all four drugs. PMID:17825517

  4. pK(a) based protonation states and microspecies for protein-ligand docking.

    Science.gov (United States)

    ten Brink, Tim; Exner, Thomas E

    2010-11-01

    In this paper we present our reworked approach to generate ligand protonation states with our structure preparation tool SPORES (Structure PrOtonation and REcognition System). SPORES can be used for the preprocessing of proteins and protein-ligand complexes as e.g. taken from the Protein Data Bank as well as for the setup of 3D ligand databases. It automatically assigns atom and bond types, generates different protonation, tautomeric states as well as different stereoisomers. In the revised version, pKa calculations with the ChemAxon software MARVIN are used either to determine the likeliness of a combinatorial generated protonation state or to determine the titrable atoms used in the combinatorial approach. Additionally, the MARVIN software is used to predict microspecies distributions of ligand molecules. Docking studies were performed with our recently introduced program PLANTS (Protein-Ligand ANT System) on all protomers resulting from the three different selection methods for the well established CCDC/ASTEX clean data set demonstrating the usefulness of especially the latter approach.

  5. Confidence intervals: am I unconsciously Bayesian?

    Directory of Open Access Journals (Sweden)

    Andrea Onofri

    2015-08-01

    Full Text Available To most biologists, the exact meaning of confidence intervals is very difficult to grasp, though such intervals are shown in many of our papers as measures of data variability. One of the reasons lies in the fact that the traditional way of teaching confidence intervals suggests much more than they actually deliver. Therefore, working with biologists, statistics teachers need a convincing way of introducing this topic and, to my experience, Monte Carlo simulation offers some opportunities. However, understanding the crude meaning of frequentist confidence intervals may be disappointing for biologists, who might be seduced by the intuitive appeal of Bayesian credible intervals.

    2016-01-01

    Who was Nicolas Rashevsky? To answer that question, this book draws on Rashevsky’s unexplored personal archival papers and shares interviews with his family, students and friends, as well as discussions with biologists and mathematical biologists, to flesh out and complete the picture. “Most modern-day biologists have never heard of Rashevsky. Why?” In what constitutes the first detailed biography of theoretical physicist Nicolas Rashevsky (1899-1972), spanning key aspects of his long scientific career, the book captures Rashevsky’s ways of thinking about the place mathematical biology should have in biology and his personal struggle for the acceptance of his views. It brings to light the tension between mathematicians, theoretical physicists and biologists when it comes to the introduction of physico-mathematical tools into biology. Rashevsky’s successes and failures in his efforts to establish mathematical biology as a subfield of biology provide an important test case for understanding the role o...

  1. Parenting and preschooler attachment among low-income urban African American families.

    Science.gov (United States)

    Barnett, D; Kidwell, S L; Leung, K H

    1998-12-01

    This study examined the parental correlates of child attachment in a preschool-aged, economically disadvantaged, urban, African American sample. Sixty-nine 4- to 5-year-olds and their primary caregivers participated in the Strange Situation assessment procedure. Based on Cassidy and Marvin's classification system for preschoolers, 61% of the children were classified as securely attached, with girls being significantly more likely to be securely attached than boys (74% versus 45%). The majority of the insecure attachments were of the avoidant variety. Consistent with attachment theory, parents of securely attached children were rated as significantly more warm and accepting and less controlling with their children than were parents of insecurely attached preschoolers. Relative to parents of securely attached preschoolers, parents of children judged to be insecurely attached reported being more likely to use corporal punishment and less likely to use verbal reminders when their children misbehaved. Parenting was associated with attachment over and above the effects of child sex. PMID:9914645

    2004-03-01

    We study charge-induced changes in shape and electronic structure for n-doped single-walled carbon nanotubes within density functional theory. A certain nearly free electron state is downshifted in the presence of extra electrons. A similar effect has been seen in potassium-doped carbon nanotubes [1], where the downshift was attributed to the hybridization of the nearly free electron state with the K 4s state. In the present calculation the negative charge is neutralized by a uniform positive background, so the downshift must arise from a different effect. The state crosses the Fermi level at a charge per carbon atom of 0.04 for all the tubes studied. Connections are made to recent experiments in the group of P. Eklund.[1]Yoshiyuki Miyamoto, Angel Rubio, X. Blase, Marvin L. Cohen, and Steven G. Louie PRL 74, 2993 (1995)

    Cities are increasingly becoming sites of low-carbon transitions, as Bulkeley et al. (2011) have demonstrated. For example, urban governments increasingly tend to gain degrees of control over regimes in order to achieve territorial priorities (Hodson and Marvin 2011). This reflects how urban...... governments deliberately attempt to intervene in existing sociotechnical systems in order to establish low-carbon configurations in practice.

  8. The changing features of the body-mind problem.

    Science.gov (United States)

    Agassi, Joseph

    2007-01-01

    The body-mind problem invites scientific study, since mental events are repeated and repeatable and invite testable explanations. They seemed troublesome because of the classical theory of substance that failed to solve its own central problems. These are soluble with the aid of the theory of the laws of nature, particularly in its emergentist version [Bunge, M., 1980. The Body-mind Problem, Pergamon, Oxford] that invites refutable explanations [Popper, K.R., 1959. The Logic of Scientific Discovery, Hutchinson, London]. The view of mental properties as emergent is a modification of the two chief classical views, materialism and dualism. As this view invites testable explanations of events of the inner world, it is better than the quasi-behaviorist view of self-awareness as computer-style self-monitoring [Minsky, M., Laske, O., 1992. A conversation with Marvin Minsky. AI Magazine 13 (3), 31-45]. PMID:18261888

  12. A rapid method for the evaluation of the ionic permeabilities across epithelial cell membranes.

    Science.gov (United States)

    Movileanu, L

    1999-02-01

    This short note presents a recipe for the calculation of the ionic permeabilities across epithelial cell membranes. The method requires the Goldman-Hodgkin-Katz formalism as well as the consideration of the equivalent electrical circuit for an epithelial cell. The equivalent electrical circuit is solved in terms of the equivalent electromotive forces coupled in series with the ionic resistances of both cell membranes (apical and basolateral). The present procedure is feasible for any leaky epithelial cell membrane with the condition that this membrane (apical or basolateral) does not contain primary or secondary mechanisms for active transport.

    Let $\\mathcal{G}(S,\\rho)$ be a graph whose vertices are complex projective structures with holonomy $\\rho$ and whose edges are graftings from one vertex to another. If $\\rho$ is quasi-Fuchsian, a theorem of Goldman implies that $\\mathcal{G}(S,\\rho)$ is contractible. If $\\rho$ is a quasi-Fuchsian Schottky group Baba has shown that $\\mathcal{G}(S,\\rho)$ is connected. We show that if $\\rho$ is a quasi-Fuchsian Schottky group $\\pi_1(\\mathcal{G}(S,\\rho))$ is not finitely generated and there are an infinte number of (standard) projective structures which can be grafted to a common structure.

    Since the release of Goldman Sach's 'Path to 2050' report, arguing the combined economies of Brazil, Russia, India and China, would ellipse the economies of the current richest countries by 2050, the BRIC countries have garnered global attention. As demand for oil in these nations increases, NOCs within the BRIC have gone beyond national borders for exploration and financing - giving rise to concerns over emerging policies, objectives and priorities. The purpose of this paper is to examine NOCs of the BRIC and their compliance with international standards of corporate social responsibility and their effects through international capital markets.

    2011-11-01

    The Goldman-Albus treatment of the action-potential dynamics is combined with a phenomenological description of molecular hyperpolarizabilities into a closed-form model of the action-potential-sensitive second-harmonic response of myelinated nerve fibers with nodes of Ranvier. This response is shown to be sensitive to nerve demyelination, thus enabling an optical diagnosis of various demyelinating diseases, including multiple sclerosis. The model is applied to examine the nonlinear-optical response of a three-neuron reverberating circuit—the basic element of short-term memory.

    1994-05-01

    In December 1987, Central Maine Power (CMP) instituted the first competitive bidding program that allowed developers to propose installation of conservation measures. Since then, about 30 utilities in 14 states have solicited bids from energy service companies (ESCOs) and customers to reduce energy demand in residential homes and in commercial and industrial facilities. Interest in the use of competitive procurement mechanisms for demand-side resources continues to grow. In this study, the authors build upon earlier work conducted by LBL in collaboration with others (Goldman and Busch 1992; Wolcott and Goldman 1992). They have developed methods to compare bid prices and program costs among utilities. They also characterize approaches used by utilities and developers to allocate risks associated with DSM resources based on their review of a large sample of signed contracts. These contracts are analyzed in some detail because they provide insights into the evolving roles and responsibilities of utilities, customers, and third party contractors in providing demand-side management (DSM) services. The analysis also highlights differences in the allocation of risks between traditional utility rebate programs and DSM bidding programs.

    Full Text Available Alberto Goldman,1 Uwe Wollina2 1Clinica Goldman, Porto Alegre RS, Brazil; 2Department of Dermatology and Allergology, Academic Teaching Hospital Dresden-Friedrichstadt, Dresden, Germany Abstract: Permanent makeup is a cosmetic tattoo that is used to enhance one’s appearance, and which has become more popular among middle-aged and elderly women. A couple of benefits seem to be associated with permanent tattoos in the elderly: saving time (wake up with makeup; poor eyesight (difficult to apply makeup; and saving money. On the other hand, cosmetic tattoos bear the same risks as other tattoo procedures. We report on fading and unintended hyperpigmentation after tattooing on eyebrows and eyelids, and discuss the scientific and anatomical background behind the possible cause. Dermatochalasis may be a possible risk factor for excessive unwanted discolorations. Q-switched neodymium-doped yttrium aluminum garnet laser is an appropriate and safe therapeutic tool that can manage such adverse effects. Consumer protection warrants better information and education of the risks of cosmetic tattoos – in particular, for elderly women.

    Full Text Available Owing to have the capability of representing realities of life, novel has replaced epic in the age of Renaissance and industrial revolution and in the first half of the 20th century. George Lukacs has introduced realistic novel as the main form of literary genres corresponding with bourgeois society. Later on his follower, Lucien Goldman, has considered any literary work which is compatible with realism as a valuable work. Therefore, according to these two Marxist thinkers, there are a number of characters who are problematic due to their commitment to sound values and principles in realistic novels. According to Lukacs and Goldman problematic protagonist is a problematic, futureless and protesting person who inquires about noble and original human values. Considering a number of similarities and differences, the action and performance of such protagonists also exist in Iranian realistic novels. In this study as the problematic protagonist is described and explained, the novels of Modir-e Madrese (school head by Jalal-e Al-e Ahmad and Sovashoon by Simin-e Daneshvar are analyzed with regard to this aspect. The protagonists of these two novels (the head and Yousef are introduced as problematic characters because of their disagreement with corrupt society.

  13. Ontologies and standards in bioscience research: for machine or for human

    Directory of Open Access Journals (Sweden)

    2011-02-01

    Full Text Available Ontologies and standards are very important parts of today’s bioscience research. With the rapid increase of biological knowledge, they provide mechanisms to better store and represent data in a controlled and structured way, so that scientists can share the data, and utilize a wide variety of software and tools to manage and analyze the data. Most of these standards are initially designed for computers to access large amounts of data that are difficult for human biologists to handle, and it is important to keep in mind that ultimately biologists are going to produce and interpret the data. While ontologies and standards must follow strict semantic rules that may not be familiar to biologists, effort must be spent to lower the learning barrier by involving biologists in the process of development, and by providing software and tool support. A standard will not succeed without support from the wider bioscience research community. Thus, it is crucial that these standards be designed not only for machines to read, but also to be scientifically accurate and intuitive to human biologists.

  15. Learning in Plants: Lessons from Mimosa pudica.

    Abramson, Charles I; Chicas-Mosier, Ana M

    2016-01-01

    This article provides an overview of the early Mimosa pudica literature; much of which is in journals not easily accessible to the reader. In contrast to the contemporary plant learning literature which is conducted primarily by plant biologists, this early literature was conducted by comparative psychologists whose goal was to search for the generality of learning phenomena such as habituation, and classical conditioning using experimental designs based on animal conditioning studies. In addition to reviewing the early literature, we hope to encourage collaborations between plant biologists and comparative psychologists by familiarizing the reader with issues in the study of learning faced by those working with animals. These issues include no consistent definition of learning phenomena and an overreliance on the use of cognition. We suggested that greater collaborative efforts be made between plant biologists and comparative psychologists if the study of plant learning is to be fully intergraded into the mainstream behavior theory.

    A mathematical model has been proposed by biologists to describe the feedback mechanism used by the Physarum Polycephalum slime mold to adapt its tubular channels while foraging two food sources $s_0$ and $s_1$. We give a proof of the fact that, under this model, the mass of the mold will eventually converge to the shortest $s_0$-$s_1$ path of the network that the mold lies on, independently of the structure of the network or of the initial mass distribution. This matches the experimental observations by the biologists and can be seen as an example of a "natural algorithm", that is, an algorithm developed by evolution over millions of years.

    Scientific visioning systems often rely upon pixel-perfect precision to produce meaningful data. Cutting-edge equipment used in the study of cell signaling is no exception; proper image alignment is critical for successful experiments. Biologists at Pacific Northwest National Laboratory put together a special multi-spectral confocal microscope that was capable of producing live images of cells and proteins in two simultaneous spectral channels. But there was a problem: the dual images resembled poorly registered Sunday comics and were unusable. This article describes how the biologists worked with programmers to fix the difficulty and make the microscope a truly useful and unique device.

  4. The Meteoritical Quincentennial: The Stone of Ensisheim 1492-1992

    Marvin, U. B.

    1992-07-01

    This year marks the 500th anniversary of the fall of a meteorite at Ensisheim in Alsace. In at least two respects this event is unique in the history of meteoritics. First, this was the earliest witnessed meteorite fall in the West from which pieces are preserved. Second, it is the only meteorite of which a continuous five-century public record exists in manuscripts and books. Beginning with newsheets printed in 1492, writings about this event illuminate the evolution of ideas from a 15th century belief that stones from the sky were of miraculous origin, to an 18th century conviction that stones do not fall from the sky, to our present view that they fall in abundance, originating in interplanetary space (Marvin, 1992). This paper will highlight certain previously unexamined aspects of the story and address problems inherent in historical analysis. Unusable Maps. The fall of the stone was heralded by an explosion which, according to Sebastian Brant (1492), was heard along the valleys of the Danube, Neckar, Aare, Ill, and Rhine and in the alpine cantons of Schwyz and Uri. Contemporary maps, such as that published in The Nuremberg Chronicle of 1493, so distorted the regional geography that a fireball trajectory cannot be reconstructed on them. On modern maps, however, the areas Brant listed stretch about 150 km to the southeast of Ensisheim, a distance well within the range of sounds reported from other exploding fireballs. Newton (1891) and Marvin (1992) worked out possible trajectories that could account for the sound being heard in all named localities. This suggests that, far from exaggerating distances for dramatic effect, Brant's description may well have been accurate. If so, he compiled his information from word-of-mouth reports without reference to the rudimentary maps available in his time. The Language of Wonder. A document mounted beside the stone in the Ensisheim church stated that learned men did not know what it was: it must be supernatural, a wonder

    Kv7.1 (KCNQ1) channels are regulators of several physiological processes including vasodilatation, repolarization of cardiomyocytes, and control of secretory processes. A number of Kv7.1 pore mutants are sensitive to extracellular potassium. We hypothesized that extracellular potassium also...... modulates wild-type Kv7.1 channels. The Kv7.1 currents were measured in Xenopus laevis oocytes at different concentrations of extracellular potassium (1-50 mM).

    Peripheral vision can impact essential job functions of firefighters and other workers who use Self-Contained Breathing Apparatus and other full face masks. It is important for physicians to know how these masks alter peripheral vision. Also, one must understand the effect of monocular vision on peripheral vision. Using the Goldman Perimeter Machine we measured peripheral vision in the monocular and binocular state, with and without two different types of masks. The results show that monocularity causes an average loss of 23 degrees in the nasal meridian. The use of the masks did not affect this difference. Also, the masks caused an average loss of 28 degrees of peripheral vision in the inferior meridian. How these losses affect the ability of the users of the masks to perform their essential job functions still needs to be researched. PMID:12708146

    Ferreira, Tiago Alfredo S.; El-Hani, Charbel N.; da Silva-Filho, Waldomiro José

    2016-07-01

    This article intends to show that the defense of "understanding" as one of the major goals of science education can be grounded on an anti-reductionist perspective on testimony as a source of knowledge. To do so, we critically revisit the discussion between Harvey Siegel and Alvin Goldman about the goals of science education, especially where it involves arguments based on the epistemology of testimony. Subsequently, we come back to a discussion between Charbel N. El-Hani and Eduardo Mortimer, on the one hand, and Michael Hoffmann, on the other, striving to strengthen the claim that rather than students' belief change, understanding should have epistemic priority as a goal of science education. Based on these two lines of discussion, we conclude that the reliance on testimony as a source of knowledge is necessary to the development of a more large and comprehensive scientific understanding by science students.

  11. My Life as a Quant: Reflections on Physics and Finance

    Derman, Emanuel

    2004-09-01

    Emanuel Derman was one of the first physicists to move to Wall Street, and his career paralleled the growth of quantitative trading over the past twenty years. In My Life as a Quant, he traces his transformation from ambitious young scientist to managing director and head of the renowned Quantitative Strategies group at Goldman, Sachs & Co. Derman's tale recounts his adventures with quants, traders and other high fliers on Wall Street as he became the best-known quant in the business. He describes the struggles of research and his interactions with an assorted cast of famous scientists. He relates his impressions of some of the most creative minds on Wall Street, including Fischer Black, with whom he collaborated on the widely used Black-Derman-Toy model of interest rates. Throughout his story he reflects on the appropriate way to apply the refined methods of physics to the hurly-burly world of markets and the people that inhabit them.

    -compartment model indicate that the strong steady-state chloride current rectification cannot be obtained if only the intracellular chloride concentration and the membrane potentials are allowed to vary ("Goldman-rectification"). It is suggested, therefore, that the premeability of the chloride pathway varies...... steady-state conductance and the steady-state chloride current reveal that the chloride pathway has maximum conductance for V approximately -80 mV (outside of the skin being negative) and approaches a non-conducting safe for V greater than 0 mV. This strong outward going rectification is a steady......-state phenomenon: In skins hyperpolarized for a few minutes, the "instantaneous" I-V curves show that the chloride pathway in the conducting state allows a large inward chloride current (outward chloride flux) to pass in the voltage range 40 mV greater than V greater than 0 mV.

    2015-10-01

    The ``democratic'' mass matrix with BSM physics assumptions has been studied without success. We invert the process and use the ``democratic'' mass matrix plus a parametrization of all possible BSM corrections to analyze the implications of the observed masses and CKM weak interaction current mixing for the BSM parameter values for the up-quarks and down-quarks. We observe that the small mixing of the so-called ``third generation'' is directly related to the large mass gap from the two lighter generations. Conversely, the relatively large value of the Cabibbo angle arises because the mass matrices in the light sub-sector (block diagonalized from the full three channel problem) are neither diagonal nor degenerate and differ significantly between the up and down cases.

  16. Theory and Inference for a Class of Observation-driven Models with Application to Time Series of Counts

    CERN Document Server

    Davis, Richard A

    2012-01-01

    This paper studies theory and inference related to a class of time series models that incorporates nonlinear dynamics. It is assumed that the observations follow a one-parameter exponential family of distributions given an accompanying process that evolves as a function of lagged observations. We employ an iterated random function approach and a special coupling technique to show that, under suitable conditions on the parameter space, the conditional mean process is a geometric moment contracting Markov chain and that the observation process is absolutely regular with geometrically decaying coefficients. Moreover the asymptotic theory of the maximum likelihood estimates of the parameters is established under some mild assumptions. These models are applied to two examples; the first is the number of transactions per minute of Ericsson stock and the second is related to return times of extreme events of Goldman Sachs Group stock.

    2009-01-01

    We use high-speed x-ray imaging to reveal how a small (~10cm) desert dwelling lizard, the sandfish (Scincus scincus), swims within a granular medium [1]. On the surface, the lizard uses a standard diagonal gait, but once below the surface, the organism no longer uses limbs for propulsion. Instead it propagates a large amplitude single period sinusoidal traveling wave down its body and tail to propel itself at speeds up to ~1.5 body-length/sec. Motivated by these experiments we study a numerical model of the sandfish as it swims within a validated soft sphere Molecular Dynamics granular media simulation. We use this model as a tool to understand dynamics like flow fields and forces generated as the animal swims within the granular media.

  18. Nonlinear saturation of stimulated diffusion scattering

    International Nuclear Information System (INIS)

    A nonlinear instability theory is presented for stimulated scattering of electromagnetic ordinary-mode radiation from electrostatic ''diffusion modes.'' These ''diffusion modes'' are excited unstable by the incident radiation, and have their linear damping rates proportional to the diffusion tensor. Two diffusion modes are found; one corresponds to thermal diffusion and the other to particle diffusion. The thermal diffusion mode was previously calculated by Berger, Goldman, and DuBois for a two-dimensional model. The present calculation is made for three dimensions to show that the radiation is scattered over a wide angle in the plane perpendicular to a uniform magnetic field. A three-dimensional model is necessary to determine nonlienar effects. The saturated level of the electrostatic diffusion modes is calculated explicitly. For ionospheric modification experiments it is found that the electron density fluctuations are almost 1% of the ambient electron density

  20. Verbal processing deficits in schizophrenia.

    Science.gov (United States)

    Stevens, A A; Donegan, N H; Anderson, M; Goldman-Rakic, P S; Wexler, B E

    2000-08-01

    The authors reported that a subgroup of schizophrenic patients performed well on a tone serial position task but was impaired on an auditory word serial position task (Wexler, Stevens, Bowers, Cerniak, & Goldman-Rakic, 1998). This study assessed 30 schizophrenic and 32 controls (matched for comparable tone discrimination) on 4 versions of the verbal serial position tasks and 2 tone serial position tasks. Patients performed poorly on all verbal tasks but performed comparably to controls when tones served as stimuli. Proactive interference and visual presentation further compounded the verbal deficits. Deficits persisted with pronounceable nonword stimuli. These findings provide evidence of specific deficits in language-related processing, although the authors could not rule out the possibility that the differential effects that were observed between the tone and word tasks, and particularly among the verbal tasks, may result from differing discriminating power of the different tests.

    2007-01-01

    The twelve recognized species of nectar-feeding bats of the genus Lonchophylla occur in low- and middle-elevation, humid, Neotropical forests. Morphological and morphometrical analyses of specimens formerly lumped with Lonchophylla mordax O. Thomas (1903) support recognition of Lonchophylla concava Goldman (1914) as a separate species and reveal a third species from the western Pacific lowlands of Colombia and Ecuador that I describe herein as Lonchophylla jornicata. This new species is morphologically similar to Lonchophylla concava but is distinctively larger than that species. Tests for sexual dimorphism within these and other species of Lonchophyllini suggest a tendency for females to have slightly longer, narrower skulls, higher coronoid processes of the mandible, and longer forearms than males.

  17. A Degree Is Not Enough: A quantitative study of aspects of pre-service science teachers' chemistry content knowledge

    Science.gov (United States)

    Kind, Vanessa

    2014-05-01

    Aspects of chemistry content knowledge held by 265 UK-based pre-service teachers (PSTs) were probed using 28 diagnostic questions in five chemistry concept areas, Particle theory and changes of state, Mass conservation (taught to 11-14-year-olds), and Chemical bonding, Mole calculations and Combustion reactions (taught to 14-16-year-olds). Data were collected over six years from academically able science graduates starting a full-time, university-based teacher education programme of one academic year duration. PSTs in three sub-cohorts ('chemists', 'physicists' and 'biologists' on the basis of their undergraduate degrees) demonstrated similar levels of content knowledge (CK) for Particle theory and changes of state and Mass conservation. Biologists demonstrated statistically significantly weaker understanding than chemists and physicists in Chemical bonding, Mole calculations and Combustion reactions. Forty-four 'triads' each comprising one chemist, physicist and biologist, matched by academic and personal backgrounds, showed that chemists outperformed biologists and physicists in Chemical bonding and Combustion reactions. The findings suggest that non-chemists' CK is insufficient for teaching these chemistry concepts in high schools, despite their possession of 'good' Bachelor of Science degrees. These data have implications for science teacher education, including how best to prepare science graduates from diverse backgrounds for teaching specialist science subjects to 11-16-year-olds.
