    In May 2002, the United States Department of Energy (DOE) signed Assistance Instrument Number DE-FC09-02CH11109 with the Medical University of South Carolina (MUSC) to support the Environmental Biosciences Program (EBP). This funding instrument replaces DOE Assistance Instrument Number DE-FC02-98CH10902. EBP is an integrated, multidisciplinary scientific research program, employing a range of research initiatives to identify, study and resolve environmental health risks. These initiatives are consistent with the MUSC role as a comprehensive state-supported health sciences institution and with the nation's need for new and better approaches to the solution of a complex and expansive array of environment-related health problems. The intrinsic capabilities of a comprehensive health sciences institution enable MUSC to be a national resource for the scientific investigation of environmental health issues. EBPs success as a nationally prominent research program is due, in part, to its ability to task-organize scientific expertise from multiple disciplines in addressing these complex problems Current research projects have focused EBP talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene (TCE), polychlorinated biphenyls (PCBs), asbestos and low-dose ionizing radiation. A project is also being conducted in the use of geographical information system technology to analyze population health risks related to environmental hazards as a tool for risk-based decision-making.

    Current research projects have focused Environmental Biosciences Program (EBP) talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene, low-dose ionizing radiation (gamma and neutron) and alpha radiation from plutonium. Trichloroethylene research has been conducted as a joint collaborative effort with the University of Georgia. Work on the trichloroethylene research projects has been slowed as a result of funding uncertainties. The impact of these funding uncertainties has been discussed with the United States Department of Energy (DOE). Laboratory work has been completed on several trichloroethylene risk assessment projects, and these projects have been brought to a close. Plans for restructuring the performance schedule of the remaining trichloroethylene projects have been submitted to the department. A comprehensive manuscript on the scientific basis of trichloroethylene risk assessment is in preparation. Work on the low-dose radiation risk assessment projects is also progressing at a slowed rate as a result of funding uncertainties. It has been necessary to restructure the proponency and performance schedule of these projects, with the project on Low-Dose Radiation: Epidemiology Risk Models transferred to DOE Office of Science proponency under a separate funding instrument. Research on this project will continue under the provisions of the DOE Office of Science funding instrument, with progress reported in accordance with the requirements of that funding instrument. Progress on that project will no longer be reported in quarterly reports for DE-FC09-02CH11109. Following a meeting at the Savannah River Site on May 8, 2008, a plan was submitted for development of an epidemiological cohort study and prospective medical surveillance system for the assessment of disease rates among workers at the Savannah River

    The development of software systems for the biosciences is always closely connected to experimental practice. Programs must be able to handle the inherent complexity and heterogeneous structure of biological systems in combination with the measuring equipment. Moreover, a high degree of flexibility is required to treat rapidly changing experimental conditions. Object-oriented methodology seems to be well suited for this purpose. It enables an evolutionary approach to software development that still maintains a high degree of modularity. This paper presents experience with object-oriented technology gathered during several years of programming in the fields of bioprocess development and metabolic engineering. It concentrates on the aspects of experimental support, data analysis, interaction and visualization. Several examples are presented and discussed in the general context of the experimental cycle of knowledge acquisition, thus pointing out the benefits and problems of object-oriented technology in the specific application field of the biosciences. Finally, some strategies for future development are described.

    1996-12-31

    Since initiation in mid 1994, a bioscience nuclear microscopy program at Livermore has enabled collaboration with bio-scientists on a variety of projects requiring quantitative elemental microanalysis. For microprobe analysis a combination of PIXE and STIM are typically used; respectively generating element distribution maps with micron scale spatial resolution, and projected densities and histological information with sub-micron spatial resolution. Current studies demonstrate the applicability of nuclear microscopy (particularly when combined with other analysis techniques) in environmental tracing, toxicology, carcinogenesis, and structural biology. The program currently uses {approximately}10 percent of the available time on a 10 MV tandem accelerator that is also applied to a variety of Accelerator Mass Spectrometry and other microprobe programs. The completion of a dedicated nuclear microprobe system, using a 5 SDH NEC 1.7 MV tandem accelerator and employing several energy dispersive x-ray detectors to improve x-ray counting rates, promises increased accelerator access, greater sample throughput and continued expansion of the program.

  1. In what ways do the experiences of students in PhD programs in the molecular biosciences foster knowledge transfer?

    Science.gov (United States)

    Prevost, Amy C.

    Doctoral training in the molecular biosciences often fails to prepare students for academic and alternate careers. Several studies of doctoral training have reported a need to improve doctoral education; outlining specific criticisms related to the need to broaden the scope of the doctoral degree in order to prepare students for careers. The development of doctoral students' knowledge transfer skills is the key to making this transition. The theory advanced in this study extends the literature on doctoral education related to student experiences that foster the development of knowledge transfer skills. These insights will be a resource for academic leaders as they develop new programs and the re-develop existing ones; to students and graduates as they become leaders in their field; and to mentors, who have a large role in the development of doctoral students. Research conducted for this dissertation led to the development of theory about elements of the doctoral experience that foster the development of knowledge transfer skills in the molecular biosciences. In exploring ways the experiences of students in PhD programs in the molecular biosciences foster knowledge transfer, I was able to develop a framework for understanding these experiences in the context of doctoral programs. Students' experiences are affected by different elements of doctoral education. As they develop identities as researchers and scientists, and transition from novices to experts, students' experiences are shaped by their mentors, peers, programs and departments. Subjects spoke about their experiences in interviews. This study exposed a need to balance support and challenge for doctoral students to allow them to develop the capacity to perform scientific research and act as leaders. The development of knowledge transfer skills within this context is important preparation for students in the molecular biosciences. Doctoral students in this area need to apply their expertise in increasingly

    In May 2002, the United States Department of Energy (DOE) signed Assistance Instrument Number DE-FC09-02CH11109 with the Medical University of South Carolina (MUSC) to support the Environmental Biosciences Program (EBP). This funding instrument replaces DOE Assistance Instrument Number DE-FC02-98CH10902. EBP is an integrated, multidisciplinary scientific research program, employing a range of research initiatives to identify, study and resolve environmental health risks. These initiatives are consistent with the MUSC role as a comprehensive state-supported health sciences institution and with the nation's need for new and better approaches to the solution of a complex and expansive array of environment-related health problems. The intrinsic capabilities of a comprehensive health sciences institution enable MUSC to be a national resource for the scientific investigation of environmental health issues. EBPs success as a nationally prominent research program is due, in part, to its ability to task-organize scientific expertise from multiple disciplines in addressing these complex problems. Current research projects have focused EBP talent and resources on providing the scientific basis for risk-based standards, risk-based decision making and the accelerated clean-up of widespread environmental hazards. These hazards include trichloroethylene and low-dose ionizing radiation. Work on the trichloroethylene research projects has been slowed as a result of funding uncertainties. The impact of these funding uncertainties has been discussed with the DOE. Plans for restructuring the performance schedule of the trichloroethylene projects have been submitted to the department. A project is also being conducted in the use of geographical information system technology to analyze population health risks related to environmental hazards as a tool for risk-based decision-making.

    The Center for Synchrotron Biosciences (CSB) operates five beamlines at the National Synchrotron Light Source (NSLS). Infrared (IR) micro-spectroscopy, X-ray absorption spectroscopy, structural proteomics and macromolecular footprinting are among the major technologies available through the Center. IR micro-spectroscopy is used to examine protein-folding in the microsecond time regime, image bone, neurons, seeds and other biological tissues, as well as image samples of interest in the chemical and environmental sciences. Structural proteomics research of New York Structural Genomics Research Consortium (NYSGRC) is steadily increasing the number of solved protein structures, with a goal to solve 100-200 structures per year. To speed up the research, a high-throughput method called 'metallomics' was implemented for NYSGRC crystallographers to detect intrinsic anomalous scatterers using X-ray absorption spectroscopy. Hydroxyl radical mediated X-ray footprinting is capable of resolving folding events of RNA, at single base resolution on millisecond timescales using a synchrotron white beam. The high brightness of synchrotron source is essential for CSB projects as it permits the use of smaller sample sizes and/or concentration, and allows studies of more complicated biological systems than with conventional sources.

    A mixed methods survey of fourth-year medical students, resident physicians, and residency program directors at the Indiana University School of Medicine gathered perceptions of anatomical competence-defined as the anatomical education necessary for effective clinical practice. The survey items explored numerous aspects of anatomical competence, including the most effective modes of instruction, perceptions of readiness for clinical practice, and specific suggestions for improving anatomical education during medical school and residency. The response rate was 46% for fourth-year medical students, 47% for residents (as graduates from 137 medical schools), and 71% for program directors. A majority of students and residents reported that their course in Gross Anatomy prepared them well for clinical practice; that cadaveric dissection was important in the early development of their anatomical competence; and that placing a greater emphasis on clinical relevance in medical school would have improved their anatomical competence even further. However, in terms of anatomical preparedness upon entering residency, the program directors rated their residents less prepared than the residents rated themselves. All three groups agreed that there is need for additional opportunities for anatomical educational during medical school and residency. Suggestions for improving anatomical education included the following: providing more opportunities for cadaveric dissection during medical school and residency; more consistent teaching of anatomy for clinical practice; more workshops that review anatomy; and better integration of anatomy with the teaching of other subjects during medical school.

    Advances in salivary bioscience enable unique opportunities to explore individual differences in biological mechanisms related to learning and memory, psychiatric disorders, and more recently neurodegenerative diseases, neurotrauma/stroke, pain, and sleep. Sampling oral fluid is not only minimally invasive, but specimens can be collected easily and quickly in clinical and field settings. Salivary analytes allow neuroscientists to index endocrine, autonomic, immune, metabolic, and inflammatory processes within close proximity of discrete behavioral, biological, and social events, which is particularly important to advancing our understanding of human neuroscience. This review provides an update on the advances in salivary bioscience for specialty fields within neuroscience, presents novel salivary analytes of interest to neuroscience and the status of their development, and outlines a procedural framework to facilitate integration of these concepts and methods into neuroscience.

    Scientists founded the Life Sciences Research Foundation (LSRF) in 1983 as a non-profit pass through foundation that awards post doctoral fellowships in all areas of the life sciences. LSRF scientists review hundreds of applications each year from PhDs seeking support. For example this year, our 26th, we received 800 applications and our peer review committee will choose about 50 finalists who are eligible for these awards. We have no endowment so we solicit sponsors each year. The fellowships are sponsored by research oriented companies, foundations, philanthropists, the Howard Hughes Medical Institute, and other organizations who believe in the value of awarding fellowships to the best and the brightest young scientists. Our web site has a complete listing of all details about LSRF (http://www.lsrf.org/). In the late 1980s the Division of Bioscience in the Office of Basic Energy Science, a granting agency of the Department of Energy, joined this partnership. Bioscience's mandate was to support non-medical microbiology and plant sciences. LSRF received a series of 5 year grants from DOE to award fellowships to our top applicants in these fields of research. We began to support DOE-Energy Bioscience post doctoral fellows in 1989. From 1989 through 2004 when DOE funding ended our partnership awarded 41 DOE-Energy Bioscience Fellows of the Life Sciences Research Foundation. Each of these was a three year fellowship. DOE-Energy Biosciences was well matched with LSRF. Our extensive peer review screened applicants in all areas of the life sciences. Most LSRF sponsors are interested in supporting fellows who work on diseases. At the time that we began our partnership with DOE we had no sponsors willing to support plant biology and non medical microbiology. For 15 years DOE played a major role in the training of the very best young scientists in these important fields of research simply through its support of LSRF post doctoral fellows.

    1992-12-01

    The Northeast Regional Biomass Program has been in operation for a period of nine years. During this time, state managed programs and technical programs have been conducted covering a wide range of activities primarily aim at the use and applications of wood as a fuel. These activities include: assessments of available biomass resources; surveys to determine what industries, businesses, institutions, and utility companies use wood and wood waste for fuel; and workshops, seminars, and demonstrations to provide technical assistance. In the Northeast, an estimated 6.2 million tons of wood are used in the commercial and industrial sector, where 12.5 million cords are used for residential heating annually. Of this useage, 1504.7 mw of power has been generated from biomass. The use of wood energy products has had substantial employment and income benefits in the region. Although wood and woodwaste have received primary emphasis in the regional program, the use of municipal solid waste has received increased emphasis as an energy source. The energy contribution of biomass will increase as potentia users become more familiar with existing feedstocks, technologies, and applications. The Northeast Regional Biomass Program is designed to support region-specific to overcome near-term barriers to biomass energy use.

    The Site Operator Program was initially established by the Department of Energy (DOE) to incorporate the electric vehicle activities dictated by the Electric and Hybrid Vehicle Research, Development and Demonstration Act of 1976. In the ensuing years, the Program has evolved in response to new legislation and interests. The Program currently includes twelve sites located in diverse geographic, metrologic, and metropolitan areas across the US. Information is shared reciprocally with a thirteenth site, not under Program contract. The vehicles are operator-owned, except for two Griffon vans. The Mission Statement of the Site Operator Program includes three major activities: advancement of electric vehicle technologies; development of infrastructure elements necessary to support significant electric vehicle use; and increasing the awareness and acceptance of electric vehicles (EVs) by the public. The current participants in the Site Operator Program are shown. The ultimate thrust of program activities varies among sites, reflecting not only the Operator`s business interests but also geographic and climate-related operating conditions. This fourth quarter report (FY-94) includes a summary of activities from the previous three quarters. The report section sequence has been revised to provide a more easily seen program overview, and specific operator activities are now found in Appendix A.

    In this Letter we will analyze the creation of the multiverse. We will first calculate the wave function for the multiverse using third quantization. Then we will fourth-quantize this theory. We will show that there is no single vacuum state for this theory. Thus, we can end up with a multiverse, even after starting from a vacuum state. This will be used as a possible explanation for the creation of the multiverse. We also analyze the effect of interactions in this fourth-quantized theory.

    Full Text Available In this communication we introduce a general framework and discussion on the role of models and the modelling process within the scientific activity in the biosciences realm. The objective is sum up the common procedure during the formalization and analysis of a biological problem under the foundations of Systems Biology, which approach the study of biological systems as a whole.We begin by presenting the definitions of (biological system and model. Particular attention is given to the meaning of mathematical model within the context of the biology. Then, we present the modelization and analysis process of biological systems. Three stages are described in detail: conceptualization of the biological system into a model, mathematical formalization of the previous conceptual model and optimization and system management derived from the analysis of the mathematical model.All along this presentation the main features and shortcomings of the process are developed together with a set of rules that could help in the modelling endeavour of any biological system. Special regard is given to the formative requirements and the interdisciplinary nature of this approach. We conclude with some general considerations on the challenges that the modelling are currently posing to the current biology.

    The field of epigenetics is now on a geometric rise, driven in a large part by the realization that modifiers of chromatin are key regulators of biological processes in vivo. The three major classes of epigenetic effectors are DNA methylation, histone post-translational modifications (such as acetylation, methylation or phosphorylation) and small noncoding RNAs (most notably microRNAs). In this article, I report from Select Biosciences Epigenetics Europe 2010 industry conference held on 14-15 September 2010 at The Burlington Hotel, Dublin, Ireland. This industry conference was extremely well attended with a global pool of delegates representing the academic research community, biotechnology companies and pharmaceutical companies, as well as the technology/tool developers. This conference represented the current state of the epigenetics community with cancer/oncology as a key driver. In fact, it has been estimated that approximately 45% of epigenetic researchers today identify cancer/oncology as their main area of focus vis-à-vis their epigenetic research efforts.

    Bioinformatics and computational biology play a critical role in bioscience and biomedical research. As researchers design their experimental projects, one major challenge is to find the most relevant bioinformatics toolkits that will lead to new knowledge discovery from their data. The Bio-TDS (Bioscience Query Tool Discovery Systems, http://biotds.org/) has been developed to assist researchers in retrieving the most applicable analytic tools by allowing them to formulate their questions as free text. The Bio-TDS is a flexible retrieval system that affords users from multiple bioscience domains (e.g. genomic, proteomic, bio-imaging) the ability to query over 12 000 analytic tool descriptions integrated from well-established, community repositories. One of the primary components of the Bio-TDS is the ontology and natural language processing workflow for annotation, curation, query processing, and evaluation. The Bio-TDS's scientific impact was evaluated using sample questions posed by researchers retrieved from Biostars, a site focusing on BIOLOGICAL DATA ANALYSIS: The Bio-TDS was compared to five similar bioscience analytic tool retrieval systems with the Bio-TDS outperforming the others in terms of relevance and completeness. The Bio-TDS offers researchers the capacity to associate their bioscience question with the most relevant computational toolsets required for the data analysis in their knowledge discovery process.

  8. DOE Safety Metrics Indicator Program (SMIP) Fiscal Year 2001 Fourth Quarter Report of Packaging- and Transportation-related Occurrences

    Energy Technology Data Exchange (ETDEWEB)

    2001-11-30

    The Safety Metrics Indicator Program (SMIP) retrieved 44 packaging- or transportation-related occurrences from the Occurrence Reporting and Processing System (ORPS) during the period from July 1 through September 30, 2001. Only those incidents that occur in preparation for transport, during transport, and during unloading of hazardous material are considered as packaging- or transportation-related occurrences. Other incidents with packaging and transportation (P and T) significance but not involving hazardous material (such as vehicle accidents or empty packagings) are not rated to the SMIP criteria, but are archived in the SMIP Subsidiary Database of occurrences, a sub-database of the main SMIP P and T Occurrence Database. Thirty-two of the originally-selected 44 occurrences were appropriate for classification to the SMIP criteria, only 7 of which have offsite applicability. Eight of the original 44 reports are archived in a subsidiary database because they either do not involve the transport of hazardous material or do not involve transport by vehicle, plane, boat, or rail. The others either were deleted because more thorough review revealed that they were not strictly related to P and T or were canceled by the reporting site and removed from the ORPS. These occurrences have not been normalized as in the Annual Report of Occurrences because the necessary information is not yet available. The number and severity of the selected occurrence reports (ORs) are consistent with historical reporting. Contamination events continue to be among the most common type of occurrences; however, ''Shipping Preparation'' events decreased this quarter to only 4 events from the 21 reported last quarter. None of the 32 ORs that were rated had event consequence measures (W{sub EC}) greater than 2; 14 of them were categorized as having a W{sub EC} of 1. This means that all of the fourth-quarter FY 2001 ORs had only slight consequences at worst (i.e., resulting in

  14. Fluorescence lifetime imaging in biosciences: technologies and applications

    Institute of Scientific and Technical Information of China (English)

    Raluca NIESNER; Karl-Heinz GERICKE

    2008-01-01

    The biosciences require the development of methods that allow a non-invasive and rapid investigation of biological systems. In this aspect, high-end imaging tech-niques allow intravital microscopy in real-time, providing information on a molecular basis. Far-field fluorescence imaging techniques are some of the most adequate methods for such investigations. However, there are great differences between the common fluorescence imaging techniques, i.e., wide-field, confocal one-photon and two-photon microscopy, as far as their applicability in diverse bioscientific research areas is concerned. In the first part of this work, we briefly compare these techniques. Standard methods used in the biosciences, i.e., steady-state techniques based on the analy-sis of the total fluorescence signal originating from the sam-ple, can successfully be employed in the study of cell, tissue and organ morphology as well as in monitoring the macro-scopic tissue function. However, they are mostly inadequate for the quantitative investigation of the cellular function at the molecular level. The intrinsic disadvantages of steady-state techniques are countered by using time-resolved tech-niques. Among these fluorescence lifetime imaging (FLIM) is currently the most common. Different FLIM principles as well as applications of particular relevance for the biosci-ences, especially for fast intravital studies are discussed in this work.

    Full Text Available This study is expected to determine the impact of a program based on the cooperative learning methodology. This, in comparison to a traditional learning situation in both mathematics and language achievement. The study was carried out on a group of fourth grade students of primary school. In addition, it tried to find the differential impact according to the cognitive style in the field dependence-independence dimension. This work was carried out with 76 students of the Colegio José Martí I.E.D. (Bogotá-Colombia ranging from 8-12 years of age. The control group received a traditional teaching methodology and the experimental group received the cooperative learning program, composed of 35 sessions (from July to November 2009. All the participants were tested in mathematics and language performance, before and after the intervention. All of them were tested in cognitive style as well. The results suggested that the cooperative learning methodology benefited importantly the academic achievement of the students in mathematics in contrast to the competitive and individualist situations. The results also suggested that the three cognitive style groups were positively affected from the cooperative learning situation. These results were not found in the language area.

  1. Full text and figure display improves bioscience literature search.

    Directory of Open Access Journals (Sweden)

    Anna Divoli

    Full Text Available When reading bioscience journal articles, many researchers focus attention on the figures and their captions. This observation led to the development of the BioText literature search engine, a freely available Web-based application that allows biologists to search over the contents of Open Access Journals, and see figures from the articles displayed directly in the search results. This article presents a qualitative assessment of this system in the form of a usability study with 20 biologist participants using and commenting on the system. 19 out of 20 participants expressed a desire to use a bioscience literature search engine that displays articles' figures alongside the full text search results. 15 out of 20 participants said they would use a caption search and figure display interface either frequently or sometimes, while 4 said rarely and 1 said undecided. 10 out of 20 participants said they would use a tool for searching the text of tables and their captions either frequently or sometimes, while 7 said they would use it rarely if at all, 2 said they would never use it, and 1 was undecided. This study found evidence, supporting results of an earlier study, that bioscience literature search systems such as PubMed should show figures from articles alongside search results. It also found evidence that full text and captions should be searched along with the article title, metadata, and abstract. Finally, for a subset of users and information needs, allowing for explicit search within captions for figures and tables is a useful function, but it is not entirely clear how to cleanly integrate this within a more general literature search interface. Such a facility supports Open Access publishing efforts, as it requires access to full text of documents and the lifting of restrictions in order to show figures in the search interface.

    Nutrigenomics is a subspecialty of nutrition science which aims to understand how gene-diet interactions influence individuals' response to food, disease susceptibility, and population health. Yet ethical enquiry into this field is being outpaced by nutrigenomics bioscience. The ethical issues surrounding nutrigenomics face the challenges of a rapidly evolving field which bring forward the additional dimension of crossdisciplinary integrative research between social and biomedical sciences. This article outlines the emerging nutrigenomics definitions and concepts and analyzes the existing ethics literature concerning personalized nutrition and presents "points to consider" over ethical issues regarding future nutrigenomics applications. The interest in nutrigenomics coincides with a shift in emphasis in medicine and biosciences toward prevention of future disease susceptibilities rather than treatment of already established disease. Hence, unique ethical issues emerge concerning the extent to which nutrigenomics can alter our relation to food, boundaries between health and disease, and the folklore of medical practice. Nutrigenomics can result in new social values, norms, and responsibilities for both individuals and societies. Nutrigenomics is not only another new application of "-omics" technologies in the context of gene-diet interactions. Nutrigenomics may fundamentally change the way we perceive human illness while shifting the focus and broadening the scope of health interventions from patients to healthy individuals. In resource- and time-limited healthcare settings, this creates unique ethical dilemmas and distributive justice issues. Ethical aspects of nutrigenomics applications should be addressed proactively, as this new science develops and increasingly coalesces with other applications of genomics in medicine and public health.

    We estimated genetic gains for popcorn varieties using selection indexes in a fourth cycle of intrapopulation recurrent selection developed in the campus of the Universidade Estadual do Norte Fluminense. Two hundred full-sib families were obtained from the popcorn population UNB-2U of the third recurrent selection cycle. The progenies were evaluated in a randomized block design with two replications at sites in two different environments: the Colégio Estadual Agrícola Antônio Sarlo, in Campos dos Goytacazes, and the Empresa de Pesquisa Agropecuária do Estado do Rio de Janeiro (PESAGRO-RIO), in Itaocara, both in the State of Rio de Janeiro. There were significant differences between families within sets in all traits, indicating genetic variability that could be exploited in future cycles. Thirty full-sib families were selected to continue the program. The selection indexes used to predict the gains were those of Mulamba and Mock, Smith and Hazel. The best results were obtained with the Mulamba and Mock index, which allowed the prediction of negative gains for the traits number of diseased ears and ears attacked by pests, number of broken plants and lodging, as well as ears with poor husk cover. It also provided higher gains for popping expansion and grain yield than with the other indexes, giving values of 10.55 and 8.50%, respectively, based on tentatively assigned random weights.

     This book presents the latest developments and applications of computational tools related to the biosciences and medical engineering. It also reports the findings of different multi-disciplinary research projects, for example, from the areas of scaffolds and synthetic bones, implants and medical devices, and medical materials. It is also shown that the application of computational tools often requires mathematical and experimental methods. Computational tools such as the finite element methods, computer-aided design and optimization as well as visualization techniques such as computed axial tomography open up completely new research fields that combine the fields of engineering and bio/medical. Nevertheless, there are still hurdles since both directions are based on quite different ways of education. Often even the “language” can vary from discipline to discipline.

  9. Annual report and summaries of FY 1993 activities: Division of Energy Biosciences

    Energy Technology Data Exchange (ETDEWEB)

    1993-09-01

    The mission of the Energy Biosciences program is to generate fundamental information about plants and non-health related microorganisms that will constitute the base for new biotechnologies as well as supply information to improve usages of such organisms in their current form. The collective aims are totally consistent with the Department of Energy`s objectives of developing alternate energy sources, replacements for otherwise fossil energy derived products and providing critical fundamental information for the preservation and restoration of environmental conditions affected by energy related activities. The EB program takes full advantage of its organizational locale in the Office of Basic Energy Sciences to directly interact with such disciplines as Materials Sciences, Chemistry, Engineering and Geosciences to promote cross-disciplinary research and planning activities. One of the major specific objectives of the EB program is to probe the enormous capabilities of the specified organisms to carry out biochemical conversions. The limitation to realization of entirely new products and processes via biotechnology is the lack of basic understanding of natural processes. Such knowledge will then afford the advantage of developing procedures to the benefit of people and their society in providing new products along with providing new employment possibilities. This document consists of abstracts of projects supported in FY 1993.

  11. Foods: Where Innovation, Agriculture, Molecular Biosciences and Human Nutrition Meet

    Directory of Open Access Journals (Sweden)

    Charles Brennan

    2012-11-01

    Full Text Available There is one commodity the world over that unites mankind—food. In 2011 the United Nations claimed that the world’s population had reached the seven billion mark, a number which is set to increase dramatically in the decades to come. Food security, supply and sustainability are of paramount concern to the future economic and social progress of humanity. It is the responsibility of the food industry, together with food scientists and technologists, to shoulder the burden of ensuring an adequate supply of nutritious, safe and sensorially acceptable foods for a range of demanding consumers. In responding to this challenge, we need to understand the link between agriculture, engineering, food processing, molecular biosciences, human nutrition, commercialisation and innovation. Access to information concerning the composition and quality of foods has never been so easy for consumers and technologists alike. A plethora of research publications are made available each month to scientists and associated interested parties. The outcomes of these research manuscripts are often distilled and disseminated into messages available to everyone through bulletin boards, forums and the popular press. Newspapers and new agencies constantly report on the latest pharma-medical finding, or news regarding food safety and security concerns. We live in an age where information is so readily available to everyone that the task of finding credible and reputable data can be difficult at times. Providing sound evidenced based research is where a peer-reviewed journal can provide clarity. [...

  12. Automatic categorization of diverse experimental information in the bioscience literature

    2012-01-01

    Full Text Available Abstract Background Curation of information from bioscience literature into biological knowledge databases is a crucial way of capturing experimental information in a computable form. During the biocuration process, a critical first step is to identify from all published literature the papers that contain results for a specific data type the curator is interested in annotating. This step normally requires curators to manually examine many papers to ascertain which few contain information of interest and thus, is usually time consuming. We developed an automatic method for identifying papers containing these curation data types among a large pool of published scientific papers based on the machine learning method Support Vector Machine (SVM. This classification system is completely automatic and can be readily applied to diverse experimental data types. It has been in use in production for automatic categorization of 10 different experimental datatypes in the biocuration process at WormBase for the past two years and it is in the process of being adopted in the biocuration process at FlyBase and the Saccharomyces Genome Database (SGD. We anticipate that this method can be readily adopted by various databases in the biocuration community and thereby greatly reducing time spent on an otherwise laborious and demanding task. We also developed a simple, readily automated procedure to utilize training papers of similar data types from different bodies of literature such as C. elegans and D. melanogaster to identify papers with any of these data types for a single database. This approach has great significance because for some data types, especially those of low occurrence, a single corpus often does not have enough training papers to achieve satisfactory performance. Results We successfully tested the method on ten data types from WormBase, fifteen data types from FlyBase and three data types from Mouse Genomics Informatics (MGI. It is being used in

    Efstathiou, Nikolaos; Bailey, Cara

    2012-01-01

    This paper considers the challenges of bioscience teaching and learning in pre-registration nurse education. Effective learning requires active student participation which is problematic when teaching large groups of students. New technologies, such as the audience response system (ARS), have been introduced to increase student participation and support them in the understanding of complex bioscience concepts. Within one university department, an evaluation was undertaken to identify the perceptions of pre-registration nurse students on the use of ARS in the teaching and learning of bioscience. Our findings concur with others that ARS increases student participation and aids in identifying misconceptions and in correcting them. Students found ARS very useful and wanted ARS to be used in additional modules too. Although ARS did not seem to motivate students to study adequately before attending the relevant sessions, it increased discussion among students and awareness of their level of knowledge compared to their peers. Further research is required to identify the effectiveness of ARS in the teaching and learning of bioscience and its impact on the performance of the students in their final assessments.

    In response to a condition of the National Pollutant Discharge Elimination System (NPDES) permit issued to Oak Ridge National Laboratory (ORNL) on April 1, 1986, a Biological Monitoring and Abatement Program (BMAP) was developed for White Oak Creek (WOC) and selected tributaries. BMAP currently consists of six major tasks that address both radiological and nonradiological contaminants in the aquatic and terrestrial environs on-site and the aquatic environs off-site. These tasks are (1) toxicity monitoring, (2) bioaccumulation monitoring of nonradiological contaminants in aquatic biota, (3) biological indicator studies, (4) instream ecological monitoring, (5) assessment of contaminants in the terrestrial environment, and (6) radioecology of WOC and White Oak Lake. The ecological characterization of the WOC watershed will provide baseline data that can be used to document the ecological effects of the water pollution control program and the remedial action program. The long-term nature of BMAP ensures that the effectiveness of remedial measures will be properly evaluated.

    This paper focuses on 'triple helix' effects in biosciences. Scientific change can have profound socioeconomic effects. The molecular biology revolution tilted pharmaceuticals production away from its fine chemistry path dependence into microbiology and biotechnology. The key to any triple helix effects has thus shifted to universities and spinouts buttressed with burgeoning public funding, leaving 'big pharma' increasingly playing the role of licenser and marketer of bought-in therapeutic tr...

  4. Fourth Order Theories Without Ghosts

    CERN Document Server

    Mannheim, P D; Mannheim, Philip D.; Davidson, Aharon

    2000-01-01

    Using the Dirac constraint method we show that the pure fourth-order Pais-Uhlenbeck oscillator model is free of observable negative norm states. Even though such ghosts do appear when the fourth order theory is coupled to a second order one, the limit in which the second order action is switched off is found to be a highly singular one in which these states move off shell. Given this result, construction of a fully unitary, renormalizable, gravitational theory based on a purely fourth order action in 4 dimensions now appears feasible.

  5. Fourth Light at Paranal!

    2000-09-01

    VLT YEPUN Joins ANTU, KUEYEN and MELIPAL It was a historical moment last night (September 3 - 4, 2000) in the VLT Control Room at the Paranal Observatory , after nearly 15 years of hard work. Finally, four teams of astronomers and engineers were sitting at the terminals - and each team with access to an 8.2-m telescope! From now on, the powerful "Paranal Quartet" will be observing night after night, with a combined mirror surface of more than 210 m 2. And beginning next year, some of them will be linked to form part of the unique VLT Interferometer with unparalleled sensitivity and image sharpness. YEPUN "First Light" Early in the evening, the fourth 8.2-m Unit Telescope, YEPUN , was pointed to the sky for the first time and successfully achieved "First Light". Following a few technical exposures, a series of "first light" photos was made of several astronomical objects with the VLT Test Camera. This instrument was also used for the three previous "First Light" events for ANTU ( May 1998 ), KUEYEN ( March 1999 ) and MELIPAL ( January 2000 ). These images served to evaluate provisionally the performance of the new telescope, mainly in terms of mechanical and optical quality. The ESO staff were very pleased with the results and pronounced YEPUN fit for the subsequent commissioning phase. When the name YEPUN was first given to the fourth VLT Unit Telescope, it was supposed to mean "Sirius" in the Mapuche language. However, doubts have since arisen about this translation and a detailed investigation now indicates that the correct meaning is "Venus" (as the Evening Star). For a detailed explanation, please consult the essay On the Meaning of "YEPUN" , now available at the ESO website. The first images At 21:39 hrs local time (01:39 UT), YEPUN was turned to point in the direction of a dense Milky Way field, near the border between the constellations Sagitta (The Arrow) and Aquila (The Eagle). A guide star was acquired and the active optics system quickly optimized the

    Full Text Available Objectives: Childhood obesity continues to be a problem. Children in rural populations are more likely to be overweight or obese and a lack of resources in those areas may contribute to this problem. We aimed to assess the impact of a pilot pharmacy health-care professional out-of-school time vigorous physical activity and nutrition education program on fourth and fifth graders in a rural Texas community. Methods: We conducted a prospective 12-week cohort study from August to November 2012. Thirty-three children, aged 8–11 years, in Bailey County, Texas, were enrolled in the study. Body mass index, body mass index percentile, blood pressure, waist circumference, and a diet preferences and activities knowledge survey were obtained at 0, 4, 8, and 12 weeks. Study participants completed a twice weekly physical activity and nutrition education program with exercise over weeks 1–4 with no intervention during weeks 5–12. Results: Thirty-one (94% of the 33 children, predominately Hispanic girls, completed the program. Body mass index (−0.30 (95% confidence interval, −0.44 to −0.17; P = <0.0001, body mass index percentile (−2.75 (95% confidence interval, −4.89 to −0.62; P = 0.0026, systolic blood pressure (−1.9 (95% confidence interval, −2.9 to −0.9; P = <0.0001, and waist circumference (−0.47 (95% confidence interval, −0.85 to −0.10; P = <0.0001 mean change decreased between baseline and week 12 with no intervention for 8 weeks. Positive survey results at 3 months indicated a decrease in fried/sweet foods; increase in exercise; decreases in video games and computer use; and a change in knowledge regarding the selection of the most healthy food group servings per day. Conclusion: In this pharmacy health-care directed pilot study, participants had a reduction of body mass index, body mass index percentile, systolic blood pressure, waist circumference, and improvement in certain survey results at the

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

    Directory of Open Access Journals (Sweden)

    Huaiyu eMi

    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.

    We consider model-independent constraints on the fourth-generation fermion masses and the magnitude of the D-term contribution to the scalar masses. We find that the ratio of vacuum expectation values is limited to the range 1/5 ~ 150 GeV. A general feature of the four-generation models is thus a heavy spectrum of sparticles.

  11. The Fourth Way in Finland

    Directory of Open Access Journals (Sweden)

    Vesa Iitti

    2008-01-01

    Full Text Available This article focuses on the general history of the Fourth Way in Finland. The Fourth Way, or simply ‘the Work’, began as a Greco-Armenian man named Georges Ivanovich Gurdjieff (1866?–1949 gathered groups of pupils in St Petersburg and Moscow in 1912. To these groups, Gurdjieff started to teach what he had learned and synthesized between ca 1896 and 1912 during his travels on spiritual search of Egypt, Crete, Sumeria, Assyria, the Holy Land, Mecca, Ethiopia, Sudan, India, Afghanistan, the northern valleys of Siberia, and Tibet. Neither Gurdjieff nor any of his disciples called themselves a church, a sect, or anything alike, but referred to themselves simply as ‘the Work’, or as ‘the Fourth Way’. The name ‘the Fourth Way’ originates in a Gurdjieffian view that there are essentially three traditional ways of spiritual work: those of a monk, a fakir, and a yogi. These ways do not literally refer to the activities of a monk, a fakir, and a yogi, but to similar types of spiritual work emphasizing exercise of emotion, body, or mind. Gurdjieff’s teaching is a blend of various influences that include Suf­ism, orthodox Christianity, Buddhism, Kabbalah, and general elem­ents of various occult teachings of both the East and the West. Gurdjieff’s teaching is a blend of various influences that include Suf­ism, orthodox Christianity, Buddhism, Kabbalah, and general elem­ents of various occult teachings of both the East and the West. It is a unique combination of cosmology, psychology, theory of evolution, and overall theory and practise aiming to help individ­uals in their efforts towards what is called ‘self-remembering’.

    Hare, Dominic J; New, Elizabeth J

    2016-07-12

    Biomedical research has moved on from the study of the structure of organs, cells and organelles. Today, the key questions that must be addressed to understand the body in health and disease are related to fundamental biochemistry: the distribution and speciation of chemicals, the regulation of chemical reactions, and the control of chemical environments. To see advances in this field, it is essential for analytical chemists to actively engage in this process, from beginning to end. In this Feature Article, we review the progress that has been made towards gaining an understanding of the chemistry of the body, while commenting on the intrinsic disconnect between new innovations in the field of analytical chemistry and practical application within the biosciences. We identify the challenges that prevent chemists from making a greater impact in this field, and highlight key steps for moving forward.

    Biomedical researchers often have to work on massive, detailed, and heterogeneous datasets that raise new challenges of information management. This study reports an investigation into the nature of the problems faced by the researchers in two bioscience test laboratories when dealing with their data management applications. Data were collected using ethnographic observations, questionnaires, and semi-structured interviews. The major problems identified in working with these systems were related to data organization, publications, and collaboration. The interoperability standards were analyzed using a C4I framework at the level of connection, communication, consolidation, and collaboration. Such an analysis was found to be useful in judging the capabilities of data management systems at different levels of technological competency. While collaboration and system interoperability are the “must have” attributes of these biomedical scientific laboratory information management applications, usability and human interoperability are the other design concerns that must also be addressed for easy use and implementation.

    Directory of Open Access Journals (Sweden)

    Marina Levina

    2010-03-01

    Full Text Available In this essay, I argue that the rise of personal genomics is technologically, economically, and most importantly, discursively tied to the rise of network subjectivity, an imperative of which is an understanding of self as always already a subject in the network. I illustrate how personal genomics takes full advantage of social media technology and network subjectivity to advertise a new way of doing research that emphasizes collaboration between researchers and its members. Sharing one’s genetic information is considered to be an act of citizenship, precisely because it is good for the network. Here members are encouraged to think of themselves as dividuals, or nodes, in the network and their actions acquire value based on that imperative. Therefore, citizen bioscience is intricately tied, both in discourse and practices, to the growth of the network in the age of new media.

    2016-02-01

    The essay is an empirical case study of famed British scientist Francis Crick. Viewing him as a 'cross-worlds influencer' who was moreover dedicated to a cause, I have tried to understand how these two characteristics influenced the trajectory of his long career and how they shaped his contributions to the diverse research fields in which he was active, and concluded that these characteristics reconfigure Crick's career into a coherent whole. First, I identify a major thread running through Crick's career: helping organise 'un-disciplined' new research fields, and show that his successive choices were not serendipitous but motivated by what he construed as a crusade against 'vitalism': anti-vitalism was a defining driver of his career. I then examine how Crick put his skills as a crossworlds influencer to the service of his cause, by helping organise his chosen fields of intervention. I argue that his activities as a cross-worlds influencer were an integral part of his way of 'doing science' and that his contributions to science, neuroscience in particular, should be re-evaluated in this light. This leads me to advance a possible strategy for historians to investigate big bioscience fields. Following Abir-Am, I propose to trace their genealogies back to the fluctuating semi-institutional gatherings and the institutional structures that sustained them. My research on Crick supports the view that such studies can bring insights into the question of why the contours of contemporary big bioscience endeavours have come to be shaped the way they are. Further, the essay provides a heuristic device for approaching these enquiries: 'follow the cross-worlds influencers' who worked to build and organise these semi-institutional gatherings and institutional structures.

    Chlorophyll fluorescence excitation spectra of six phytoplankton species, belonging to Bacillariophyta and Dinophyta, were dealt by fourth-derivative analysis with the Matlab program. The results show that between 350 nm and 550 nm six fluorescence peaks were found in the fourth-derivative spectra, which are representatives of non-pigments, chlorophylls and carotenoides respectively. The method makes Bacillariophyta and Dinophyta more distinguishable when the fourth-derivative spectra are compared with the chlorophyll fluorescence excitation spectra. It can be used not only to discriminate the two groups of algaes, but also to reduce the effect of noise. The fluorescence peaks in the fourth-derivative spectra are proved to be stable.

What would that imply? An intriguing possibility is that the new fermions needed to compensate for the new leptons gauge anomalies simultaneously address...

    Since the introduction of the Welsh Baccalaureate Advanced Diploma Qualification (WBQ) in 2003, an increasing number of students are applying to higher education institutions (HEIs) with this qualification. The advanced-level WBQ is regarded as equivalent to one General Certificate of Education A-Level (GCE A-Level). This study assesses the impact of attaining the WBQ in addition to three GCE A-Levels on overall university degree performance in comparison to attaining four GCE A-Levels, in three cohorts of undergraduate students (Year 1 = 318, Year 2 = 280, Year 3 = 236) studying Biosciences from 2005 to 2011 at a UK HEI. Binary logistic regression was used to compare the academic attainment of students who had achieved four GCE A-Levels to those who had achieved three GCE A-Levels in addition to the WBQ. Comparisons were also made between students who had achieved three GCE A-Levels and those who had achieved three GCE A-Levels in addition to the WBQ. The results suggest that students who achieved the WBQ qualification in its current form, in addition to three GCE A-Levels, performed less well academically in undergraduate studies than those who achieved four GCE A-Levels. Furthermore, this effect was still present when the balance between coursework and examination was considered, and when students who had achieved the WBQ in addition to three GCE A-Levels were compared to students who had achieved three GCE A-Levels.

    Deregulation is haltingly changing the United States electricity markets. The resulting uncertainty and/or rising energy costs can be hedged by generating electricity on-site and other benefits, such as use of otherwise wasted heat, can be captured. The Public Utility Regulatory Policy Act (PURPA) of 1978 first invited relatively small-scale generators ({ge} 1 MW) into the electricity market. The advent of efficient and reliable small scale and renewable equipment has spurred an industry that has, in recent years, made even smaller (business scale) electricity generation an economically viable option for some consumers. On-site energy capture and/or conversion, known as distributed energy resources (DER), offers consumers many benefits, such as economic savings and price predictability, improved reliability, control over power quality, and emissions reductions. Despite these benefits, DER adoption can be a daunting move to a customer accustomed to simply paying a monthly utility bill. San Diego is in many ways an attractive location for DER development: It has high electricity prices typical of California and a moderate climate i.e. energy loads are consistent throughout the year. Additionally, the price shock to San Diego Gas and Electric (SDG&E) customers during the summer of 2000 has interested many in alternatives to electricity price vulnerability. This report examines the business case for DER at the San Diego biotechnology supply company, BD Biosciences Pharmingen, which considered DER for a building with 200-300 kW base-load, much of which accommodates the refrigerators required to maintain chemicals. Because of the Mediterranean climate of the San Diego area and the high rate of air changes required due to on-site use of chemicals, modest space heating is required throughout the year. Employees work in the building during normal weekday business hours, and daily peak loads are typically about 500 kW.

    2016-05-01

    Full Text Available Assessing the quality of tests and disseminating the results has been implemented in the international arena with the aim of improving testing and professional practice. Assessing tests provides users with an independent review, which follows clearly defined procedures and criteria. In Spain, the Spanish Association of Psychology (COP leads the “test evaluation” project, which has recently completed its fourth edition. Basically, there are two primary assessment models; the Buros model and the European Federation of Psychologists’ Associations (EFPA model, which has been adopted by the COP. The two models share the same objectives and content; excluding the evaluation format and the management system, they are similar in essence. In this paper, we present the results of the fourth edition of the Spanish test evaluation program following the general guidelines for assessing the quality of tests, and we explain the critical points affecting each phase of the process

    Full Text Available Abstract Background Next generation sequencing (NGS technology has revolutionized genomic and genetic research. The pace of change in this area is rapid with three major new sequencing platforms having been released in 2011: Ion Torrent’s PGM, Pacific Biosciences’ RS and the Illumina MiSeq. Here we compare the results obtained with those platforms to the performance of the Illumina HiSeq, the current market leader. In order to compare these platforms, and get sufficient coverage depth to allow meaningful analysis, we have sequenced a set of 4 microbial genomes with mean GC content ranging from 19.3 to 67.7%. Together, these represent a comprehensive range of genome content. Here we report our analysis of that sequence data in terms of coverage distribution, bias, GC distribution, variant detection and accuracy. Results Sequence generated by Ion Torrent, MiSeq and Pacific Biosciences technologies displays near perfect coverage behaviour on GC-rich, neutral and moderately AT-rich genomes, but a profound bias was observed upon sequencing the extremely AT-rich genome of Plasmodium falciparum on the PGM, resulting in no coverage for approximately 30% of the genome. We analysed the ability to call variants from each platform and found that we could call slightly more variants from Ion Torrent data compared to MiSeq data, but at the expense of a higher false positive rate. Variant calling from Pacific Biosciences data was possible but higher coverage depth was required. Context specific errors were observed in both PGM and MiSeq data, but not in that from the Pacific Biosciences platform. Conclusions All three fast turnaround sequencers evaluated here were able to generate usable sequence. However there are key differences between the quality of that data and the applications it will support.

  11. Reflective writing as a tool for assessing teamwork in bioscience: insights into student performance and understanding of teamwork.

    Mayne, Lynne

    2012-07-01

    To ensure a modern bioscience curriculum that responds to the current needs of stakeholders, there is a need to embed a range of generic capabilities that enables graduates to succeed in and contribute to a rapidly changing world, as well as building strong bioscience skills and knowledge. The curriculum must also prepare students for a rapidly evolving competitive work place and align with the needs of industry. This creates a challenge, how do we develop generic capabilities without losing discipline content. This report analyses teamwork projects embedded in an undergraduate Biotechnology degree designed to promote teamwork skills along with a deeper understanding of the underpinning biochemistry. Student reflective writing was used to capture students' understanding and experience of teamwork as well as provide insight into their metacognition. The analysis demonstrates that 73% of Year 3 and 93% of Year 4 students were capable of learning about teamwork through reflective writing. While the importance of frequent high quality communication was a common theme, evidence suggests that many students were unsophisticated in their use of communication software. The analysis also highlighted the depth of metacognition that underpins successful team function and the significant weaknesses in self-insight some students possess. These findings challenge assumptions regarding student capacity for leadership and the ability of some students to contribute to successful team outcomes. It is essential for the design of teamwork experiences to fully understand the competencies that underlie teamwork, the metacognitive processes required, and ensure that assessments are fair and measure individual academic performance.

  14. The Naturalness of the Fourth SM Family

    CERN Document Server

    Sultansoy, S

    2009-01-01

    The necessity of the fourth family follows from the SM basics. According to flavor democracy the Dirac masses of the fourth SM family fermions are almost equal with preferable value 450 GeV, which corresponds to common (for all fundamental fermions) Yukawa coupling equal to SU(2) gauge coupling gW. In principle, one expect u4 a little bit lighter than d4, while nu4 could be essentially lighter than l4 due to Majorana mass terms for right-handed components of neutrinos. Obviously, the fourth family quarks will be copiously produced at the LHC. However, the first indication of the fourth SM family may be provided by early Higgs boson observation due to almost an order enhancement of the gluon fusion to Higgs cross-section. For the same reason the Tevatron still has a chance to observe the Higgs boson before the LHC. Concerning the fourth family leptons, in general, best place will be NLC/CLIC. However, for some mass regions and MNS matrix elements double discovery of both the nu4 and H could be possible at the ...

    Blaber, Elizabeth; Dvorochkin, Natalya; Almeida, Eduardo; Fitzpatrick, Garret; Ellingson, Lance; Mitchell, Sarah; Yang, Anthony; Kosnik, Cristine; Rayl, Nicole; Cannon, Tom; Austin, Edward; Sato, Kevin

    With the recent call by the 2011 Decadal Report and the 2010 Space Biosciences Roadmap for the International Space Station (ISS) to be used as a National Laboratory for scientific research, there is now a need for new laboratory instruments on ISS to enable such research to occur. The Bioculture System supports the extended culturing of multiple cell types and microbiological specimens. It consists of a docking station that carries ten independent incubation units or ‘Cassettes’. Each Cassette contains a cooling chamber (5(°) C) for temperature sensitive solutions and samples, or long duration fluids and sample storage, as well as an incubation chamber (ambient up to 42(°) C). Each Cassette houses an independent fluidics system comprised of a biochamber, medical-grade fluid tubing, medium warming module, oxygenation module, fluid pump, and sixteen solenoid valves for automated biochamber injections of sampling. The Bioculture System provides the user with the ability to select the incubation temperature, fluid flow rate and automated biochamber sampling or injection events for each separate Cassette. Furthermore, the ISS crew can access the biochamber, media bag, and accessory bags on-orbit using the Microgravity Science Glovebox. The Bioculture System also permits initiation of cultures, subculturing, injection of compounds, and removal of samples for on-orbit processing using ISS facilities. The Bioculture System therefore provides a unique opportunity for the study of stem cells and other cell types in space. The first validation flight of the Bioculture System will be conducted on SpaceX5, consisting of 8 Cassettes and lasting for 30-37 days. During this flight we plan to culture two different mammalian cell types in bioreactors: a mouse osteocytic-like cell line, and human induced pluripotent stem cell (iPS)-derived cardiomyocytes. Specifically, the osteocytic line will enable the study of a type of cell that has been flown on the Bioculture System

    2008-01-01

    We consider the contributions to $g_\\mu-2$ from fourth generation heavy neutral and charged leptons, $N$ and $E$, at the one-loop level. Diagrammatically, there are two types of contributions: boson-boson-$N$, and $E$-$E$-boson in the loop diagram. In general, the effect from $N$ is suppressed by off-diagonal lepton mixing matrix elements. For $E$, we consider flavor changing neutral couplings arising from various New Physics models, which are stringently constrained by $\\mu\\to e\\gamma$. We assess how the existence of a fourth generation would affect these New Physics models.

    In this paper, we investigate Jacobi pseudospectral method for fourth order problems.We establish some basic results on the Jacobi-Gauss-type interpolations in non-uniformly weighted Sobolev spaces, which serve as important tools in analysis of numerical quadratures, and numerical methods of differential and integral equations. Then we propose Jacobi pseudospectral schemes for several singular problems and multiple-dimensional problems of fourth order. Numerical results demonstrate the spectral accuracy of these schemes,and coincide well with theoretical analysis.

The disciples of Jesus have been appointed as his agents to continue his mission after his departure to his Father. In giving this message through to his readers, the Fourth Evangelist refers to Jesus' calling of his disciples, [Foreign font omitted]; pictures Jesus as [Foreign font omitted]; uses [Foreign font omitted] (the particle of comparison to compare the lives of the disciples with that of Jesus; points out the tasks the disciples had to perform after Jesus' ascension and, finally, indicates how Jesus dwells in his disciples through the Paraclete.

  9. The "fourth dimension" of gene transcription.

    Science.gov (United States)

    O'Malley, Bert W

    2009-05-01

    The three dimensions of space provide our relationship to position on the earth, but the fourth dimension of time has an equally profound influence on our lives. Everything from light and sound to weather and biology operate on the principle of measurable temporal periodicity. Consequently, a wide variety of time clocks affect all aspects of our existence. The annual (and biannual) cycles of activity, metabolism, and mating, the monthly physiological clocks of women and men, and the 24-h diurnal rhythms of humans are prime examples. Should it be surprising to us that the fourth dimension also impinges upon gene expression and that the genome itself is regulated by the fastest running of all biological clocks? Recent evidence substantiates the existence of such a ubiquitin-dependent transcriptional clock that is based upon the activation and destruction of transcriptional coactivators.

  13. Fourth order difference methods for hyperbolic IBVP's

    Science.gov (United States)

    Gustafsson, Bertil; Olsson, Pelle

    1994-01-01

    Fourth order difference approximations of initial-boundary value problems for hyperbolic partial differential equations are considered. We use the method of lines approach with both explicit and compact implicit difference operators in space. The explicit operator satisfies an energy estimate leading to strict stability. For the implicit operator we develop boundary conditions and give a complete proof of strong stability using the Laplace transform technique. We also present numerical experiments for the linear advection equation and Burgers' equation with discontinuities in the solution or in its derivative. The first equation is used for modeling contact discontinuities in fluid dynamics, the second one for modeling shocks and rarefaction waves. The time discretization is done with a third order Runge-Kutta TVD method. For solutions with discontinuities in the solution itself we add a filter based on second order viscosity. In case of the non-linear Burger's equation we use a flux splitting technique that results in an energy estimate for certain different approximations, in which case also an entropy condition is fulfilled. In particular we shall demonstrate that the unsplit conservative form produces a non-physical shock instead of the physically correct rarefaction wave. In the numerical experiments we compare our fourth order methods with a standard second order one and with a third order TVD-method. The results show that the fourth order methods are the only ones that give good results for all the considered test problems.

  14. Art meets mathematics in the fourth dimension

    CERN Document Server

    Lipscomb, Stephen Leon

    2014-01-01

    To see objects that live in the fourth dimension we humans would need to add a fourth dimension to our three-dimensional vision. An example of such an object that lives in the fourth dimension is a hyper-sphere or “3-sphere”. The quest to imagine the elusive 3-sphere has deep historical roots: medieval poet Dante Alighieri, in his circa 1300 AD Divine Comedy, used a 3-sphere to convey his allegorical vision of the Christian afterlife. In 1917, Albert Einstein visualized the universe, at each instant in time, as a 3-sphere. He described his representation as “…the place where the reader’s imagination boggles. Nobody can imagine this thing.” Over time, however, our understanding of the concept of dimension evolved. By 2003, a researcher had successfully rendered into human vision the structure of a 4-web (think of an every increasingly-dense spider’s web). In this text Stephen Lipscomb takes his innovative dimension theory research a step further, using the 4-web to reveal a new partial image of a...

  15. Telling time in the Fourth Gospel

    Directory of Open Access Journals (Sweden)

    Jerome H. Neyrey

    2008-01-01

    Full Text Available When we begin the task of telling time in the Fourth Gospel, we bring something not found in any previous study, namely, a model of time articulated by cross- ultural anthropologists (Bordieu, in Pitt-Rivers 1963:55-72, Ayoade, in Wright 1984:71-89. As much as we admire Davies’ study, she has no notes to her chapter on time nor any citations in her bibliography to indicate that she has any conversation partners, much less cultural experts, a deficit to be filled in this study. Learning to tell time entails three theoretical considerations: a definition of time, key classifications of it, and special attention to what the ancients meant by past, present and future. With these lenses we are prepared to do as thorough a study as we can on telling time in the Fourth Gospel. As we consider each classification, we will suggest a brief meaning of it from the experts on time, then present a body of Greco-Roman materials illustrative of the classification, and finally use it to gather and interpret data in John. Proving the native existence of these classifications for telling time in antiquity is essential for readers to have a background against which to compare their usage with that of the Fourth Gospel.

    2012-02-01

    For 20 years the Naval Research Laboratory has been making continuous water vapor profile measurements at 22.235 GHz with the Water Vapor Millimeter-Wave Spectrometer (WVMS) instruments, with the program expanding from one to three instruments in the first 6 years. Since the initial deployments there have been gradual improvements in the instrument design which have improved data quality and reduced maintenance requirements. Recent technological developments have made it possible to entirely redesign the instrument and improve not only the quality of the measurements but also the capability of the instrument. We present the fourth-generation instrument now operating at Table Mountain, California, which incorporates the most recent advances in microwave radiometry. This instrument represents the most significant extension of our measurement capability to date, enabling us to measure middle atmospheric water vapor from ˜26-80 km.

    We consider the contributions to $g_\\mu-2$ from fourth generation neutral and charged leptons, $N$ and $E$, at the one-loop level. Diagramatically, there are two types of contributions: boson-boson-$N$, and $E$-$E$-boson in the loop diagram. In general, the effect from $N$ is suppressed by off-diagonal PMNS matrix element $V_{N\\mu}$, from the Standard Model to the Two-Higgs Doublet Models. With contribution from $E$, we consider flavor changing neutral couplings.

  6. Navigating Bioethical Waters: Two Pilot Projects in Problem-Based Learning for Future Bioscience and Biotechnology Professionals.

    Berry, Roberta M; Levine, Aaron D; Kirkman, Robert; Blake, Laura Palucki; Drake, Matthew

    2016-12-01

    We believe that the professional responsibility of bioscience and biotechnology professionals includes a social responsibility to contribute to the resolution of ethically fraught policy problems generated by their work. It follows that educators have a professional responsibility to prepare future professionals to discharge this responsibility. This essay discusses two pilot projects in ethics pedagogy focused on particularly challenging policy problems, which we call "fractious problems". The projects aimed to advance future professionals' acquisition of "fractious problem navigational" skills, a set of skills designed to enable broad and deep understanding of fractious problems and the design of good policy resolutions for them. A secondary objective was to enhance future professionals' motivation to apply these skills to help their communities resolve these problems. The projects employed "problem based learning" courses to advance these learning objectives. A new assessment instrument, "Skills for Science/Engineering Ethics Test" (SkillSET), was designed and administered to measure the success of the courses in doing so. This essay first discusses the rationale for the pilot projects, and then describes the design of the pilot courses and presents the results of our assessment using SkillSET in the first pilot project and the revised SkillSET 2.0 in the second pilot project. The essay concludes with discussion of observations and results.

    Sherwood, Brent

    1994-09-01

    Conceptual designs for fourth-generation crew-carrying Mars transfer and excursion vehicles, fully integrated to state-of-the-art standards, are presented. The resulting vehicle concepts are sized for six crew members, and can support all opposition and conjunction opportunities in or after 2014. The modular, reusable transfer ship is launched to Earth orbit on six 185-ton-class boosters and assembled there robotically. Its dual nuclear-thermal rocket engines use liquid hydrogen propollant. The payload consists of a microgravity habitation system and an expendable lift-to-drag = 1.6 lander capable of aeromaneuvering to sites within +/- 20 deg of the equator. This lander can deliver either an expendable, storable-bipropellant crew-carrying ascent vehicle, or 40 tons of cargo, and it is capable of limited surface mobility to support base buildup. Multiple cargo landers sent ahead on robotic transfer vehicles deliver the supplies and equipment required for long-duration surface missions.

    Pichierri, Angelo; Ruggeri, Andrea; Morselli, Carlotta; Delfini, Roberto

    2011-08-01

    Fourth ventricle meningiomas (FVMs) are rare, often misdiagnosed, lesions. To the best of our knowledge, 47 cases have been reported in the literature: we describe our series of three cases treated at our Institution, focusing on some diagnostic tips and intraoperative features of these tumours. Our three patients have a history of headache. Gait disturbances, vomiting and/or diplopia complicated the clinical picture before the referral at our Department. The operations were uneventful, and the patients fully recovered from neurological symptoms. They are free of recurrence at a median follow-up of 19 years. FVMs are rare lesions, which are difficult to differentiate preoperatively from the much more common ependymomas. A preoperative distinction would be extremely advantageous: indeed, although both tumours share similar radiological and clinical patterns, they clearly differ as to surgical difficulty and outcome. In fact, meningiomas are comparatively easier to remove, granting better clinical results.

  11. Fourth World Theory: The Evolution of . . .

    Directory of Open Access Journals (Sweden)

    Olon F. Dotson

    2014-05-01

    Full Text Available Fourth World theory is a methodology for examining and developing greater understanding of the extent of the distress and abandonment commonly found in the cores of American cities resulting from de-industrialization, historic segregation and discrimination patterns, suburban sprawl, erosion of a viable tax base, racism, inability to embrace the concept of desegregation and civil rights legislation, fear, despair, crumbling infrastructure systems, disinvestment in urban school systems, and environmental justice issues. This article uses the analytical lens of Fourth World theory to examine how such structural and cultural forces contributed to the severely distressed conditions now found in the city of Gary, Indiana. Tracking its one-hundred-year history, from its founding as an industrial town through its post-industrial decline occurring during the city’s first African-American mayor’s five terms in office, the methodology clearly demonstrates how the social construction of race has systematically undermined every aspect of Gary’s overall quality of life. To illustrate that this city is not an anomaly but rather reflects a typical pattern of disparity and uneven development arising from racist practices, Gary is compared to other cities of similar size and also to the much larger Detroit. The article triangulates academic literature, news media archives, and an oral history provided by the mayor to show how Gary evolved from being a model industrial city to a cauldron of racial disparity. The paper concludes by arguing that continued absence of reflection on the nation’s historical racialization of place threatens not just impoverished communities of color, but also the sustainability of the entire nation.

    The development of integrated instrumentation for universal bioassay systems serves as a key goal for the lab-on-a-chip community. The programmable bio-nano-chip (p-BNC) system is a versatile multiplexed and multiclass chemical- and bio-sensing system for bioscience and clinical measurements. The system is comprised of two main components, a disposable cartridge and a portable analyzer. The customizable single-use plastic cartridges, which now can be manufactured in high volumes using injection molding, are designed for analytical performance, ease of use, reproducibility, and low cost. These labcard devices implement high surface area nano-structured biomarker capture elements that enable high performance signaling and are index-matched to real-world biological specimens. This detection modality, along with the convenience of on-chip fluid storage in blisters and self-contained waste, represents a standard process to digitize biological signatures at the point-of-care. A companion portable analyzer prototype has been developed to integrate fluid motivation, optical detection, and automated data analysis, and it serves as the human interface for complete assay automation. In this report, we provide a systems-level perspective of the p-BNC universal biosensing platform with an emphasis on flow control, device integration, and automation. To demonstrate the flexibility of the p-BNC, we distinguish diseased and non-case patients across three significant disease applications: prostate cancer, ovarian cancer, and acute myocardial infarction. Progress towards developing a rapid 7 minute myoglobin assay is presented using the fully automated p-BNC system.

    Sahin, M.; Sultansoy, S.; Turkoz, S.

    2010-09-01

    The flavor democracy hypothesis predicts the existence of the fourth standard model family. Because of the high masses of the fourth family quarks, their anomalous decays could be dominant if certain criteria are met. This will drastically change the search strategy at hadron colliders. We show that the fourth standard model family down quarks with masses up to 400-450 GeV can be observed (or excluded) via anomalous decays by Tevatron.

  16. Mandibular asymmetry and the fourth dimension.

    Science.gov (United States)

    Kaban, Leonard B

    2009-03-01

    This paper represents more than 30 years of discussion and collaboration with Drs Joseph Murray and John Mulliken in an attempt to understand growth patterns over time (ie, fourth dimension) in patients with hemifacial microsomia (HFM). This is essential for the development of rational treatment protocols for children and adults with jaw asymmetry. Traditionally, HFM was thought of as a unilateral deformity, but it was recognized that 20% to 30% of patients had bilateral abnormalities. However, early descriptions of skeletal correction addressed almost exclusively lengthening of the short (affected) side of the face. Based on longitudinal clinical observations of unoperated HFM patients, we hypothesized that abnormal mandibular growth is the earliest skeletal manifestation and that restricted growth of the mandible plays a pivotal role in progressive distortion of both the ipsilateral and contralateral facial skeleton. This hypothesis explains the progressive nature of the asymmetry in patients with HFM and provides the rationale for surgical lengthening of the mandible in children to prevent end-stage deformity. During the past 30 years, we have learned that this phenomenon of progressive distortion of the adjacent and contralateral facial skeleton occurs with other asymmetric mandibular undergrowth (tumor resection, radiation therapy, or posttraumatic defects) and overgrowth (mandibular condylar hyperplasia) conditions. In this paper, I describe the progression of deformity with time in patients with mandibular asymmetry as a result of undergrowth and overgrowth. Understanding these concepts is critical for the development of rational treatment protocols for adults with end-stage asymmetry and for children to minimize secondary deformity.

    The Fourth World Conference on Women held in Beijing during September 4-15, 1995, was a major success. The platform for action adopted by consensus at the conference is comprised of the mission statement, a global framework, critical areas of concern, strategic objectives and actions, and institutional and financial arrangements. The conference was an extension of other large international conferences organized under UN initiative over the past 15 years. The Beijing platform of action aims to remove all obstacles to women's active participation in all spheres of public and private life through a full and equal share in economic, social, cultural, and political decision-making. The following concerns were defined by the conference: eradicating poverty, increasing school enrollment and eliminating gender inequalities in access to education, improving access to health care and eliminating gender inequalities in access to services, eliminating violence against women, mitigating the consequences of armed conflicts against women, securing equal access of men and women to economic resources and employment, providing equal participation of men and women in power structures and decision making, enhancing national mechanisms to promote the advancement of women, protecting the rights of girls and women, eradicating stereotypes about women, participating in the management of natural resources and environmental protection, and improving the status of girls.

  18. Neural crest: The fourth germ layer

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available The neural crest cells (NCCs, a transient group of cells that emerges from the dorsal aspect of the neural tube during early vertebrate development has been a fascinating group of cells because of its multipotency, long range migration through embryo and its capacity to generate a prodigious number of differentiated cell types. For these reasons, although derived from the ectoderm, the neural crest (NC has been called the fourth germ layer. The non neural ectoderm, the neural plate and the underlying mesoderm are needed for the induction and formation of NC cells. Once formed, NC cells start migrating as a wave of cells, moving away from the neuroepithelium and quickly splitting into distinct streams. These migrating NCCs home in to different regions and give rise to plethora of tissues. Umpteen number of signaling molecules are essential for formation, epithelial mesenchymal transition, delamination, migration and localization of NCC. Authors believe that a clear understanding of steps and signals involved in NC formation, migration, etc., may help in understanding the pathogenesis behind cancer metastasis and many other diseases. Hence, we have taken this review to discuss the various aspects of the NC cells.

  1. Syringomyelia regression after shunting of a trapped fourth ventricle

    Directory of Open Access Journals (Sweden)

    Dukagjin Morina

    2013-01-01

    Full Text Available We describe a case of progressive syringomyelia following post-infectious trapped fourth ventricle (TFV, which resolved after shunting of the fourth ventricle. A 28-year-old female who had previously undergone treatment of intracerebral hemorrhage and meningitis developed a hydrocephalus with TFV. After 3 years she developed disturbance of walking and coordination. Cranial-CT revealed an enlargement of the shunted fourth ventricle as a result of shunt dysfunction. Furthermore a cervical syringomyelia developed. The patient underwent a revision of a failed fourth ventriculo- peritoneal shunt. Postoperatively, syringomyelia resolved within 6 months and the associated neurological deficits improved significantly. An insufficiency of cerebrospinal fluid draining among patients with TFV can be associated with communicating syringomyelia. An early detection and treatment seems important on resolving syringomyelia and avoiding permanent neurological deficits. Ventriculo-peritoneal shunt in trapped fourth ventricles can resolve a secondary syringomyelia.

    2002-07-01

    We report on an isolated enlargement of the fourth ventricle in a patient with neurosarcoidosis which developed 3 years after the insertion of a ventriculo-atrial shunt. Repeated MRI images were obtained in a patient with known neurosarcoidosis between 1995 and 2000. Imaging findings were correlated to the medical course of the patient, who developed a hydrocephalus and a trapped fourth ventricle consecutively. The isolation was presumably due to granulomatous inflammation of the ependyma surrounding the fourth ventricular outlets. The isolated fourth ventricle was responsible for a deterioration of neurological status. Neurosarcoidosis is a severe complication in sarcoidosis patients. An isolated enlargement of the fourth ventricle is a rare complication in clinically deteriorated patients with neurosarcoidosis and ventricular drainage, which may require neurosurgical treatment.

  5. Proceedings: Fourth Workshop on Mining Scientific Datasets

    2001-07-24

    Commercial applications of data mining in areas such as e-commerce, market-basket analysis, text-mining, and web-mining have taken on a central focus in the JCDD community. However, there is a significant amount of innovative data mining work taking place in the context of scientific and engineering applications that is not well represented in the mainstream KDD conferences. For example, scientific data mining techniques are being developed and applied to diverse fields such as remote sensing, physics, chemistry, biology, astronomy, structural mechanics, computational fluid dynamics etc. In these areas, data mining frequently complements and enhances existing analysis methods based on statistics, exploratory data analysis, and domain-specific approaches. On the surface, it may appear that data from one scientific field, say genomics, is very different from another field, such as physics. However, despite their diversity, there is much that is common across the mining of scientific and engineering data. For example, techniques used to identify objects in images are very similar, regardless of whether the images came from a remote sensing application, a physics experiment, an astronomy observation, or a medical study. Further, with data mining being applied to new types of data, such as mesh data from scientific simulations, there is the opportunity to apply and extend data mining to new scientific domains. This one-day workshop brings together data miners analyzing science data and scientists from diverse fields to share their experiences, learn how techniques developed in one field can be applied in another, and better understand some of the newer techniques being developed in the KDD community. This is the fourth workshop on the topic of Mining Scientific Data sets; for information on earlier workshops, see http://www.ahpcrc.org/conferences/. This workshop continues the tradition of addressing challenging problems in a field where the diversity of applications is

    The Office of Fuels Programs prepares quarterly reports summarizing the data provided by companies authorized to import or export natural gas. Companies are required, as a condition of their authorizations, to file quarterly reports with the OFP. This report is for the fourth quarter of 1993 (October--December). Attachment A shows the percentage of takes to maximum firm contract levels and the weighted average per unit price for each of the long-term importers during the 5 most recent reporting quarters. Attachment B shows volumes and prices of gas purchased by long-term importers and exporters during the past 12 months. Attachment C shows volume and price information for gas imported on a short-term basis. Attachment D shows the gas exported on a short-term basis to Canada and Mexico. During 1993, data indicates gas imports grew by about 10 percent over the 1992 level (2328 vs. 2122 Bcf), with Canadian and Algerian imports increasing by 8 and 82 percent, respectively. During the same time period, exports declined by 41 percent (144 vs. 243 Bcf). Exports to Canada decreased 47 percent from the 1992 level (50 vs. 95 Bcf) and exports to Mexico decreased by 60 percent (38 vs. 95 Bcf).

    2001-01-01

    The HEDS-UP (Human Exploration and Development of Space-University Partners) program was instituted to build new relationships between university, faculty, students, and NASA in support of the Human Exploration and Development of Space. The program has provided a mechanism for university students to explore problems of interest to NASA through student engineering design projects, led by a university professor or mentor, and aided by the HEDS-UP staff. HEDS-UP program management advised teams on the selection of projects that were aligned with the goals of the HEDS strategic enterprise, and provided contacts with NASA and industry professionals who served as mentors. Students became acquainted with objectives, strategies, development issues, and technological characteristics of space exploration programs. In doing so, they prepared themselves for future engineering challenges, often discovering that the program was on their critical path to professional advancement. Many of the ideas were innovative and of interest to NASA. Industry benefitted from HEDS-UP as a mechanism to converge with talented students about to enter the work force. In addition, universities became more involved in the teaching of space exploration, and students were encouraged and mentored as they included education outreach as an element in their work. This in turn highlighted their performance to others and universities in their communities.

    Full Text Available Objectives: In this study we aimed to evaluate the impact of Rational Pharmacotherapy (RPT course program, reinforced by video footages, on the rational pharmacotherapy skills of the students. Materials and Methods: RPT course program has been conducted in Dokuz Eylul University School of Medicine since 2008/9. The course has been organised in accordance with World Health Organisation (WHO Good Prescribing Guide. The aim of the course was to improve the problem solving skills (methodology for selection of the (personel-drug, prescription writing and informing patient about his illness and drugs and communication skills of students. The impact of the course has been measured by pre/post-test design by an objective structured clinical examination (OSCE. In academic year 2010/11, to further improve OSCE score of the students we added doctor-patient communication video footages to the RPT course programme. During training, the students were asked to evaluate the doctor-patient communication and prescription on two video footages using a checklist followed by group discussions. Results: Total post-test OSCE score was significantly higher for 2010/11 academic year students (n = 147 than it was for 2009/10 year students (n = 131. The 2010/11 academic year students performed significantly better than the 2009/10 academic year students on four steps of OSCE. These steps were "defining the patient′s problem," "specifying the therapeutic objective," "specifying the non-pharmacological treatment" and "choosing a (drug treatment, taking all relevant patient characteristics into account". Conclusions: The present study demonstrated that the implementation of video footages and group discussions to WHO/Good Prescribing Method improved the fourth-year medical students′ performance in rational pharmacotherapy skills.

    Results are presented from a search for a fourth generation of quarks produced singly or in pairs in a data set corresponding to an integrated luminosity of 5fb-1 recorded by the CMS experiment at the LHC in 2011. A novel strategy has been developed for a combined search for quarks of the up and down type in decay channels with at least one isolated muon or electron. Limits on the mass of the fourth-generation quarks and the relevant Cabibbo-Kobayashi-Maskawa matrix elements are derived in the context of a simple extension of the standard model with a sequential fourth generation of fermions. The existence of mass-degenerate fourth-generation quarks with masses below 685 GeV is excluded at 95% confidence level for minimal off-diagonal mixing between the third- and the fourth-generation quarks. With a mass difference of 25 GeV between the quark masses, the obtained limit on the masses of the fourth-generation quarks shifts by about ±20GeV. These results significantly reduce the allowed parameter space for a fourth generation of fermions.

    Objective The superior transvelar approach is used to access pathologies located in the fourth ventricle and brainstem. The surgical path is below the venous structures, through the superior medullary velum. Following splitting the tentorial edge, near the tentorial apex, the superior medullary velum is split in the cerebello-mesencephalic fissure. Using the supracerebellar infratentorial, transtentorial or parietal interhemispheric routes, the superior medullary velum is approached. Splitting this velum provides a detailed view of the fourth ventricle and its floor. Materials and Methods A total of 10 formalin-fixed specimens were dissected in a stepwise manner to simulate the superior transvelar approach to the fourth ventricle. The exposure gained the distance from the craniotomy site and the ease of access was assessed for each of the routes. We also present an illustrative case, operated by the senior author (AN). Results The superior transvelar approach provides access to the entire length of the fourth ventricle floor, from the aqueduct to the obex, when using the parietal interhemispheric route. In addition, this approach provides access to the entire width of the floor of the fourth ventricle; however, this requires retracting the superior cerebellar peduncle. Using the supracerebellar infratentorial route gives a limited exposure of the superior part of the fourth ventricle. The occipital interhemispheric route is a compromise between these two. Conclusion The superior transvelar approach to the fourth ventricle provides a route for approaching the fourth ventricle from above. This approach does not require opening the posterior fossa in the traditional way, and provides a reasonable alternative for accessing the superior fourth ventricle.

    Full Text Available This article concerns mathematical image denoising methods incorporating fourth-order partial differential equations (PDEs. We introduce and analyze piecewise planarity conditions (PPCs with which unconstrained fourth-order variational models in continuum converge to a piecewise planar image. It has been observed that fourth-order variational models holding PPCs can restore better images than models without PPCs and second-order models. Numerical schemes are presented in detail and various examples in image denoising are provided to verify the claim.

    Childhood overweight and obesity are major health problems. School-based programs enable intervening with large groups of children, but program overall health impact is rarely completely assessed. A RE-AIM (Reach, Efficacy, Adoption, Implementation, Maintenance) analysis tested the overall public health impact of the fourth-grade "Nutrition Pathfinders" school-based nutrition-education program. A randomized controlled trial in 47 fourth-grade California classrooms (1713 students) tested program efficacy, and a secondary analysis of archival data tested program dissemination. Desired effects were seen in child nutrition knowledge, attitudes, consumption of low-nutrient high-density foods, sugar-sweetened beverages, proteins, grains, and parent willingness to serve new foods. The program was disseminated to ∼25 % of public school fourth-grade classrooms in California and cost about $1.00 per student to implement. The Nutrition Pathfinders program demonstrates potential for moderate to high public health impact due to its wide dissemination, effectiveness in altering attitudes and behaviors, and its relatively inexpensive cost of implementation.

    The fourth year of medical school remains controversial, despite efforts to reform it. A committee from the Clerkship Directors in Internal Medicine and the Association of Program Directors in Internal Medicine examined transitions from medical school to internship with the goal of better academic advising for students. In 2013 and 2014, the committee examined published literature and the Web sites of 136 Liaison Committee on Medical Education-accredited schools for information on current course offerings for the fourth year of medical school. The authors summarized temporal trends and outcomes when available.Subinternships were required by 122 (90%) of the 136 schools and allow students to experience the intern's role. Capstone courses are increasingly used to fill curricular gaps. Revisiting basic sciences in fourth-year rotations helps to reinforce concepts from earlier years. Many schools require rotations in specific settings, like emergency departments, intensive care units, or ambulatory clinics. A growing number of schools require participation in research, including during the fourth year. Students traditionally take fourth-year clinical electives to improve skills, both within their chosen specialties and in other disciplines. Some students work with underserved populations or seek experiences that will be henceforth unavailable, whereas others use electives to "audition" at desired residency sites. Fourth-year requirements vary considerably among medical schools, reflecting different missions and varied student needs. Few objective outcomes data exist to guide students' choices. Nevertheless, both medical students and educators value the fourth year of medical school and feel it can fill diverse functions in preparing for residency.

    The primary use of the LILLYPUT 3 accelerator at the Nondestructive Testing Laboratory at Wroclaw Technology Park is X-ray radiography for nondestructive testing, including R&D of novel techniques for industrial and medical imaging. The scope of possible applications could be greatly extended by providing a system for irradiation with electron beam. The purpose of this work was to design such a system, especially for high dose rate, small field irradiations under cryogenic conditions for material and bioscience research. In this work, two possible solutions, based either on beam scanning or scattering and collimation, were studied and compared. It was found that under existing conditions efficiency of both systems would be comparable. The latter one was adopted due to its simplicity and much lower cost. The system design was optimized by means of detailed Monte Carlo modeling. The system is being currently fabricated at National Centre for Nuclear Research in \\'Swierk.

    Direct dark matter searches put severe constraints on the weakly interacting massive particles (WIMPs). These constraints cause serious troubles for the model of stable neutrino of fourth generation with mass around 50GeV. Though the calculations of primordial abundance of these particles make them in the charge symmetric case a sparse subdominant component of the modern dark matter, their presence in the universe would exceed the current upper limits by several orders of the magnitude. However, if quarks and leptons of fourth generation possess their own Coulomb-like y-interaction, recombination of pairs of heavy neutrinos and antineutrinos and their annihilation in the “neutrinium” atoms can play important role in their cosmological evolution, reducing their modern abundance far below the experimental upper limits. The model of stable fourth generation assumes that the dominant part of dark matter is explained by excessive Ū antiquarks, forming (ŪŪŪ)-- charged clusters, bound with primordial helium in nuclear-interacting O-helium (OHe) dark atoms. The y charge conservation implies generation of the same excess of fourth generation neutrinos, potentially dangerous WIMP component of this scenario. We show that due to y-interaction recombination of fourth neutrinos with OHe hides these WIMPs from direct WIMP searches, leaving the negligible fraction of free neutrinos, what makes their existence compatible with the experimental constraints.

    Institute of Scientific and Technical Information of China (English)

    LI Rong; WU Xin

    2011-01-01

    Two new fourth-order three-stage symplectic integrators are specifically designed for a family of Hamiltonian systems,such as the harmonic oscillator,mathematical pendulum and lattice ψ4 model.When the nonintegrable lattice ψ4 system is taken as a test model,numerical comparisons show that the new methods have a great advantage over the second-order Verlet symplectic integrators in the accuracy of energy,become explicitly better than the usual non-gradient fourth-order seven-stage symplectic integrator of Forest and Ruth,and are almost equivalent to a fourth-order seven-stage force gradient symplectic integrator of Chin.As the most important advantage,the new integrators are convenient for solving the variational equations of many Hamiltonian systems so as to save a great deal of the computational cost when scanning a lot of orbits for chaos.

  8. Bergman kernel function on Hua construction of the fourth type

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    This paper introduces the Hua construction and presents the holomorphic automorphism group of the Hua construction of the fourth type. Utilizing the Bergman kernel function, under the condition of holomorphic automorphism and the standard complete orthonormal system of the semi-Reinhardt domain, the infinite series form of the Bergman kernel function is derived. By applying the properties of polynomial and Γ functions, various identification relations of the aforementioned form are developed and the explicit formula of the Bergman kernel function for the Hua construction of the fourth type is obtained, which suggest that many of the previously-reported results are only the special cases of our findings.

    universe. However, it does not work within the standard model due to two reasons: (1 the strength of CP violation from the Kobayashi-Maskawa mechanism with three generations is too small; (2 the electroweak phase transition is not first order for the experimentally allowed Higgs boson mass. We discuss possibilities to solve these problems by introducing a fourth generation of fermions and how electroweak baryogenesis might be revived. We also discuss briefly the recent observation of a Higgs-like boson with mass around 125 GeV, which puts the fourth generation in a difficult situation, and the possible way out.

  10. Fourth order phase-field model for local max-ent approximants applied to crack propagation

    OpenAIRE

    Amiri, Fatemeh; Millán, Daniel; Arroyo Balaguer, Marino; Silani, Mohammad; Rabczuk, Timon

    2016-01-01

    We apply a fourth order phase-field model for fracture based on local maximum entropy (LME) approximants. The higher order continuity of the meshfree LME approximants allows to directly solve the fourth order phase-field equations without splitting the fourth order differential equation into two second order differential equations. We will first show that the crack surface can be captured more accurately in the fourth order model. Furthermore, less nodes are needed for the fourth order model ...

  12. Solution to the ghost problem in fourth order derivative theories

    CERN Document Server

    Mannheim, P D

    2006-01-01

    We present a solution to the ghost problem in fourth order derivative theories. In particular we study the Pais-Uhlenbeck fourth order oscillator model, a model which serves as a prototype for theories which are based on second plus fourth order derivative actions. Via a Dirac constraint method quantization we construct the appropriate quantum-mechanical Hamiltonian and Hilbert space for the system. We find that while the second-quantized Fock space of the general Pais-Uhlenbeck model does indeed contain the negative norm energy eigenstates which are characteristic of higher derivative theories, in the limit in which we switch off the second order action, such ghost states are found to move off shell, with the spectrum of asymptotic in and out S-matrix states of the pure fourth order theory which results being found to be completely devoid of states with either negative energy or negative norm. We provide additional insight into the structure of the Pais-Uhlenbeck theory by quantizing it via path integration ...

    1997-10-14

    The Energy Information Administration (EIA) prepares quarterly short-term energy supply, demand, and price projections for printed publication in January, April, July, and October in the Short-Term Energy Outlook. The details of these projections, as well as monthly updates on or about the 6th of each interim month, are available on the internet at: www.eia.doe.gov/emeu/steo/pub/contents.html. The forecast period for this issue of the Outlook extends from the fourth quarter of 1997 through the fourth quarter of 1998. Values for the fourth quarter of 1997, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in EIA`s Weekly Petroleum Status Report) or are calculated from model simulations that use the latest exogenous information available (for example, electricity sales and generation are simulated by using actual weather data). The historical energy data, compiled in the fourth quarter 1997 version of the Short-Term Integrated Forecasting System (STIFS) database, are mostly EIA data regularly published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications. Minor discrepancies between the data in these publications and the historical data in this Outlook are due to independent rounding. The STIFS model is driven principally by three sets of assumptions or inputs: estimates of key macroeconomic variables, world oil price assumptions, and assumptions about the severity of weather. 19 tabs.

  3. Multiway Filtering Based on Fourth-Order Cumulants

    Directory of Open Access Journals (Sweden)

    Salah Bourennane

    2005-05-01

    Full Text Available We propose a new multiway filtering based on fourth-order cumulants for the denoising of noisy data tensor with correlated Gaussian noise. The classical multiway filtering is based on the TUCKALS3 algorithm that computes a lower-rank tensor approximation. The presented method relies on the statistics of the analyzed multicomponent signal. We first recall how the well-known lower rank-(K1,…,KN tensor approximation processed by TUCKALS3 alternating least square algorithm exploits second-order statistics. Then, we propose to introduce the fourth-order statistics in the TUCKALS3-based method. Indeed, the use of fourth-order cumulants enables to remove the Gaussian components of an additive noise. In the presented method the estimation of the n-mode projector on the n-mode signal subspace are built from the eigenvectors associated with the largest eigenvalues of a fourth-order cumulant slice matrix instead of a covariance matrix. Each projector is applied by means of the n-mode product operator on the n-mode of the data tensor. The qualitative results of the improved multiway TUCKALS3-based filterings are shown for the case of noise reduction in a color image and multicomponent seismic data.

    We hypothesize that chemotherapy can be safely administered directly into the fourth ventricle to treat recurrent malignant brain tumors in children. For the first time in humans, methotrexate was infused into the fourth ventricle in children with recurrent, malignant brain tumors. A catheter was surgically placed into the fourth ventricle and attached to a ventricular access device. Cerebrospinal fluid (CSF) flow was confirmed by CINE MRI postoperatively. Each cycle consisted of 4 consecutive daily methotrexate infusions (2 milligrams). Disease response was monitored with serial MRI scans and CSF cytologic analysis. Trough CSF methotrexate levels were sampled. Five patients (3 with medulloblastoma and 2 with ependymoma) received 18, 18, 12, 9, and 3 cycles, respectively. There were no serious adverse events or new neurological deficits attributed to methotrexate. Two additional enrolled patients were withdrawn prior to planned infusions due to rapid disease progression. Median serum methotrexate level 4 h after infusion was 0.04 µmol/L. Range was 0.02-0.13 µmol/L. Median trough CSF methotrexate level 24 h after infusion was 3.18 µmol/L (range 0.53-212.36 µmol/L). All three patients with medulloblastoma had partial response or stable disease until one patient had progressive disease after cycle 18. Both patients with ependymoma had progressive disease after 9 and 3 cycles, respectively. Low-dose methotrexate can be infused into the fourth ventricle without causing neurological toxicity. Some patients with recurrent medulloblastoma experience a beneficial anti-tumor effect both within the fourth ventricle and at distant sites.

    2014-01-01

    With grant funding from the John Templeton Spirituality and Medicine Curricular Award to the George Washington Institute for Spirituality and Health, faculty at Kansas City University of Medicine and Biosciences (KCUMB) developed the "Spirituality in Medicine" curriculum. In developing the curriculum, faculty took into consideration competencies required by the Association of American Medical Colleges and qualitative results from surveys of medical school applicants and enrolled students. Strategies for curriculum delivery included lectures, panel discussions, role-playing, and training in the use of a spirituality assessment tool. A majority of the 250 students who received the training in 2010-2011 were able to demonstrate the following competencies: (1) being sensitive to patients' spiritual and cultural needs, (2) assessing patients' and their own spiritual needs, (3) appropriately using chaplain services for patient care, and (4) understanding the effects of health disparities and ethical issues on patient care. Challenges to implementation included a reduction in chaplain availability due to the economic downturn, a lack of student exposure to direct patient care during shadowing, too little religious diversity among chaplains, and changes in assignment schedules. New competencies required by the National Board of Osteopathic Medical Examiners overlap with and help ensure sustainability of the Spirituality in Medicine curriculum. KCUMB leaders have incorporated the use of the spirituality assessment tool into other parts of the curriculum and into service experiences, and they have introduced a new elective in palliative care. Synergistic efforts by faculty leaders for this initiative were critical to the implementation of this curriculum.

  20. Estimation of the fourth-order dispersion coefficient β4

    Institute of Scientific and Technical Information of China (English)

    2012-01-01

    The fourth-order dispersion coefficient of fibers are estimated by the iterations around the third-order dispersion and the high-order nonlinear items in the nonlinear Schordinger equation solved by Green's function approach.Our theoretical evaluation demonstrates that the fourth-order dispersion coefficient slightly varies with distance.The fibers also record β4 values of about 0.002,0.003,and 0.00032 ps4/km for SMF,NZDSF and DCF,respectively.In the zero-dispersion regime,the high-order nonlinear effect (higher than self-steepening) has a strong impact on the transmitted short pulse.This red-shifts accelerates the symmetrical split of the pulse,although this effect is degraded rapidly with the increase of β2.Thus,the contributions to β4 of SMF,NZDSF,and DCF can be neglected.

    Full Text Available Meningioma's occurring intraventricular region are rare and these occurring in the fourth ventricle is even rare. Because of the rarity, it is not usually considered as a differential diagnosis in any age group. Clinical features and Imaging is not characteristic, and most of them are thought to be some different tumor. Here, we discuss two cases harboring a primary fourth ventricular meningioma Grade II, which was surgically excised successfully. Total excision was achieved in both cases and as the tumor was firm to soft and vermian splitting was not required. Understanding the clinical features and a careful preoperative radiological examination is required to differentiate this tumor from more commonly occurring lesions at this location.

  2. Spinal accessory nerve schwannomas masquerading as a fourth ventricular lesion

    Directory of Open Access Journals (Sweden)

    Shyam Sundar Krishnan

    2015-01-01

    Full Text Available Schwannomas are benign lesions that arise from the nerve sheath of cranial nerves. The most common schwannomas arise from the 8 th cranial nerve (the vestibulo-cochlear nerve followed by trigeminal and facial nerves and then from glossopharyngeal, vagus, and spinal accessory nerves. Schwannomas involving the oculomotor, trochlear, abducens and hypoglossal nerves are very rare. We report a very unusual spinal accessory nerve schwannoma which occupied the fourth ventricle and extended inferiorly to the upper cervical canal. The radiological features have been detailed. The diagnostic dilemma was due to its midline posterior location mimicking a fourth ventricular lesion like medulloblastoma and ependymoma. Total excision is the ideal treatment for these tumors. A brief review of literature with tabulations of the variants has been listed.

    Recent years have seen renewed interest in the study of revolutions. Yet the burgeoning interest in revolutionary events has not been matched by a comparable interest in the\\ud development of revolutionary theory. For the most part, empirical studies of revolutions remain contained within the parameters established by the ‘fourth generation’ of\\ud revolutionary theory. This body of work sees revolutions as conjunctural amalgams of systemic crisis, structural opening, and collective action, wh...

  12. US Energy Industry Financial Developments, 1993 fourth quarter, April 1994

    Energy Technology Data Exchange (ETDEWEB)

    1994-04-14

    This report traces key financial trends in the US energy industry for the fourth quarter of 1993. Financial data (only available for publicly-traded US companies) are included in two broad groups -- fossil fuel production and rate-regulated electric utilities. All financial data are taken from public sources such as energy industry corporate reports and press releases, energy trade publications, and The Wall Street Journal`s Earnings Digest; return on equity is calculated from data available from Standard and Poor`s Compustat data service. Since several major petroleum companies disclose their income by lines of business and geographic area, these data are also presented in this report. Although the disaggregated income concept varies by company and is not strictly comparable to corporate income, relative movements in income by lines of business and geographic area are summarized as useful indicators of short-term changes in the underlying profitability of these operations. Based on information provided in 1993 fourth quarter financial disclosures, the net income for 82 petroleum companies -- including 18 majors -- was unchanged between the fourth quarter of 1992 and the fourth quarter of 1993. An 18-percent decline in crude oil prices resulted in a deterioration of the performance of upstream (oil and gas production) petroleum companies during the final quarter of 1993. However, prices for refined products fell much less than the price of crude oil, resulting in higher refined product margins and downstream (refining, marketing and transport) petroleum earnings. An increase in refined product demand also contributed to the rise in downstream income.

  17. Fourth-order gravity gradient torque of spacecraft orbiting asteroids

    CERN Document Server

    Wang, Yue; Xu, Shijie

    2014-01-01

    The dynamical behavior of spacecraft around asteroids is a key element in design of such missions. An asteroid's irregular shape, non-spherical mass distribution and its rotational sate make the dynamics of spacecraft quite complex. This paper focuses on the gravity gradient torque of spacecraft around non-spherical asteroids. The gravity field of the asteroid is approximated as a 2nd degree and order-gravity field with harmonic coefficients C20 and C22. By introducing the spacecraft's higher-order inertia integrals, a full fourth-order gravity gradient torque model of the spacecraft is established through the gravitational potential derivatives. Our full fourth-order model is more precise than previous fourth-order model due to the consideration of higher-order inertia integrals of the spacecraft. Some interesting conclusions about the gravity gradient torque model are reached. Then a numerical simulation is carried out to verify our model. In the numerical simulation, a special spacecraft consisted of 36 po...

  18. Fourth-Order Difference Methods for Hyperbolic IBVPs

    Science.gov (United States)

    Gustafsson, Bertil; Olsson, Pelle

    1995-03-01

    In this paper we consider fourth-order difference approximations of initial-boundary value problems for hyperbolic partial differential equations. We use the method of lines approach with both explicit and compact implicit difference operators in space. The explicit operator satisfies an energy estimate leading to strict stability. For the implicit operator we develop boundary conditions and give a complete proof of strong stability using the Laplace transform technique. We also present numerical experiments for the linear advection equation and Burgers' equation with discontinuities in the solution or in its derivative. The first equation is used for modeling contact discontinuities in fluid dynamics; the second one is used for modeling shocks and rarefaction waves. The time discretization is done with a third-order Runge-Kutta TVD method. For solutions with discontinuities in the solution itself we add a filter based on second-order viscosity. In case of the non-linear Burgers' equation we use a flux splitting technique that results in an energy estimate for certain difference approximations, in which case also an entropy condition is fulfilled. In particular we shall demonstrate that the unsplit conservative form produces a non-physical shock instead of the physically correct rarefaction wave. In the numerical experiments we compare our fourth-order methods with a standard second-order one and with a third-order TVD method. The results show that the fourth-order methods are the only ones that give good results for all the considered test problems.

  19. Masses of a Fourth Generation with Two Higgs Doublets

    Bellantoni, Leo; Heckman, Jonathan J; Ramirez-Homs, Enrique

    2012-01-01

    We use sampling techniques to find robust constraints on the masses of a possible fourth sequential fermion generation from electroweak oblique variables. We find that in the case of a light (115 GeV) Higgs from a single electroweak symmetry breaking doublet, inverted mass hierarchies are possible for both quarks and leptons, but a mass splitting more than M(W) in the quark sector is unlikely. We also find constraints in the case of a heavy (600 GeV) Higgs in a single doublet model. As recent data from the Large Hadron Collider hints at the existence of a resonance at 124.5 GeV and a single Higgs doublet at that mass is inconsistent with a fourth fermion generation, we examine a type II two Higgs doublet model. In this model, there are ranges of parameter space where the Higgs sector can potentially counteract the effects of the fourth generation. Even so, we find that such scenarios produce qualitatively similar fermion mass distribtions.

    2016-10-01

    Full Text Available From 15 to 26 June 1955, the Romanian capital hosted the fourth edition of the European Volleyball Championship, both women and men. This edition, scheduled four years after the previous one, also registered a record of participation for those times: 14 teams entered the men’s competition and 6 attended the women’s. In the end, the Romanian men representative occupied an honourable second position in the charts, while the women were only fourth. The European titles went to Czechoslovakia, which clearly dominated the competition. The tournament was programmed to take place in Floreasca Hall and Dinamo Sports Park in Bucharest. The main aim of our present study is that of providing a detailed analysis of this sports event, which belongs to a period when the European volleyball championships did not have a regular scheduling, and the number of competing teams was not officially pre-established. Our second goal is that of framing this competition into the larger political context which deeply influenced its development. The sports event happening in Bucharest proved to be a success, both from the perspective of the quality of the featured competitions, and from the organizational point of view, thus placing the country among the select few volleyball promoters worldwide

    A maximum of forty-eight wells of the LFW series monitor groundwater quality in the Steed Pond Aquifer (Water Table) beneath the Sanitary Landfill at the Savannah River Site (SRS). These wells are sampled quarterly to comply with the South Carolina Department of Health and Environmental Control Domestic Water Permit DWP-087A and as part of the SRS Groundwater Monitoring Program. Chloroethene (vinyl chloride) and trichloroethylene were the most widespread constituents exceeding standards during 1997. Lead (total recoverable), 1,4-dichlorobenzene, mercury, benzene, dichloromethane (methylene chloride), a common laboratory contaminant, tetrachloroethylene, 1,2-dichloroethane, gross alpha, tritium, and 1.2-dichloropropane also exceeded standards in one or more wells. The groundwater flow direction in the Steed Pond Aquifer (Water Table) beneath the Sanitary Landfill was to the southeast (universal transverse Mercator coordinates). The flow rate in this unit was approximately 139 ft/year during first quarter 1997 and 132 ft/year during fourth quarter.

    Full Text Available This study focuses on the analysis of the illustrations found in five different Geography textbooks in Romania. The analysis is based on several criteria: number, size, clarity, pedagogical usefulness. The following conclusions have been drawn: the illustrations are numerous; most of the illustrations are too small and unclear to be efficiently used in the teaching activity; the purpose of some materials is purely illustrative; some illustrations are overcharged with details, which prevent children from understanding them. Authors and publishing houses are advised to choose the illustrations in the fourth class Geography textbooks more carefully.

    In this paper we study the initial boundary value problem for fourth order wave equations with nonlinear strain and source terms. First we introduce a family of potential wells and prove the invariance of some sets and vacuum isolating of solutions. Then we obtain a threshold result of global existence and nonexistence. Finally we discuss the global existence of solutions for the problem with critical initial condition I(u0)[greater-or-equal, slanted]0, E(0)=d. So the Esquivel-Avila's results are generalized and improved.

  13. Ghost-free, finite, fourth-order D = 3 gravity.

    Science.gov (United States)

    Deser, S

    2009-09-04

    Canonical analysis of a recently proposed linear + quadratic curvature gravity model in D = 3 establishes its pure, irreducibly fourth derivative, quadratic curvature limit as both ghost-free and power-counting UV finite, thereby maximally violating standard folklore. This limit is representative of a generic class whose kinetic terms are conformally invariant in any dimension, but it is unique in simultaneously avoiding the transverse-traceless graviton ghosts plaguing D > 3 quadratic actions as well as double pole propagators in its other variables. While the two-term model is also unitary, its additional mode's second-derivative nature forfeits finiteness.

  14. Scale-invariant scalar spectrum from the nonminimal derivative coupling with fourth-order term

    CERN Document Server

    Myung, Yun Soo

    2015-01-01

    An exactly scale-invariant spectrum of scalar perturbation generated during de Sitter spacetime is found from the gravity model of the nonminimal derivative coupling with fourth-order term. The nonminimal derivative coupling term generates a healthy (ghost-free) fourth-order derivative term, while the fourth-order term provides an unhealthy (ghost) fourth-order derivative term. The Harrison-Zel'dovich spectrum obtained from Fourier transforming the fourth-order propagator in de Sitter space is recovered by computing the power spectrum in its momentum space directly. It shows that this model provides a truly scale-invariant spectrum, in addition to the Lee-Wick scalar theory.

  15. Short-Term Energy Outlook: Quarterly projections. Fourth quarter 1993

    1993-11-05

    The Energy Information Administration (EIA) prepares quarterly, short-term energy supply, demand, and price projections for publication in February, May, August, and November in the Short-Term Energy Outlook (Outlook). An annual supplement analyzes the performance of previous forecasts, compares recent cases with those of other forecasting services, and discusses current topics related to the short-term energy markets. (See Short-Term Energy Outlook Annual Supplement, DOE/EIA-0202.) The forecast period for this issue of the Outlook extends from the fourth quarter of 1993 through the fourth quarter of 1994. Values for the third quarter of 1993, however, are preliminary EIA estimates (for example, some monthly values for petroleum supply and disposition are derived in part from weekly data reported in the Weekly Petroleum Status Report) or are calculated from model simulations using the latest exogenous information available (for example, electricity sales and generation are simulated using actual weather data). The historical energy data are EIA data published in the Monthly Energy Review, Petroleum Supply Monthly, and other EIA publications.

  16. Towards a fourth spatial dimension of brain activity.

    Science.gov (United States)

    Tozzi, Arturo; Peters, James F

    2016-06-01

    Current advances in neurosciences deal with the functional architecture of the central nervous system, paving the way for general theories that improve our understanding of brain activity. From topology, a strong concept comes into play in understanding brain functions, namely, the 4D space of a "hypersphere's torus", undetectable by observers living in a 3D world. The torus may be compared with a video game with biplanes in aerial combat: when a biplane flies off one edge of gaming display, it does not crash but rather it comes back from the opposite edge of the screen. Our thoughts exhibit similar behaviour, i.e. the unique ability to connect past, present and future events in a single, coherent picture as if we were allowed to watch the three screens of past-present-future "glued" together in a mental kaleidoscope. Here we hypothesize that brain functions are embedded in a imperceptible fourth spatial dimension and propose a method to empirically assess its presence. Neuroimaging fMRI series can be evaluated, looking for the topological hallmark of the presence of a fourth dimension. Indeed, there is a typical feature which reveal the existence of a functional hypersphere: the simultaneous activation of areas opposite each other on the 3D cortical surface. Our suggestion-substantiated by recent findings-that brain activity takes place on a closed, donut-like trajectory helps to solve long-standing mysteries concerning our psychological activities, such as mind-wandering, memory retrieval, consciousness and dreaming state.

    The fourth International Conference on Squeezed States and Uncertainty Relations was held at Shanxi University, Taiyuan, Shanxi, China, on June 5 - 9, 1995. This conference was jointly organized by Shanxi University, the University of Maryland (U.S.A.), and the Lebedev Physical Institute (Russia). The first meeting of this series was called the Workshop on Squeezed States and Uncertainty Relations, and was held in 1991 at College Park, Maryland. The second and third meetings in this series were hosted in 1992 by the Lebedev Institute in Moscow, and in 1993 by the University of Maryland Baltimore County, respectively. The scientific purpose of this series was initially to discuss squeezed states of light, but in recent years, the scope is becoming broad enough to include studies of uncertainty relations and squeeze transformations in all branches of physics, including, of course, quantum optics and foundations of quantum mechanics. Quantum optics will continue playing the pivotal role in the future, but the future meetings will include all branches of physics where squeeze transformations are basic transformation. This transition took place at the fourth meeting of this series held at Shanxi University in 1995. The fifth meeting in this series will be held in Budapest (Hungary) in 1997, and the principal organizer will be Jozsef Janszky of the Laboratory of Crystal Physics, P.O. Box 132, H-1052.

    Herpes simplex virus (HSV) causes acute and relapsing symptoms characterized by ulcerative lesions. Laboratory diagnosis of HSV in cutaneous or mucocutaneous lesions has historically been performed with the use of viral cell culture systems; however, these tests are laborious and suffer decreased sensitivity for advanced-stage lesions. The recent availability of FDA-cleared moderately complex assays has resulted in the increased use of molecular diagnostics for the routine detection of HSV in superficial swab specimens. We performed a clinical evaluation of the recently FDA-cleared illumigene HSV 1&2 loop-mediated isothermal amplification (LAMP) assay (Meridian Bioscience, Cincinnati OH) for the detection and differentiation of HSV-1 and HSV-2 in cutaneous and mucocutaneous swab specimens. A total of 1,153 clinical swab specimens were collected and tested at 7 different clinical centers. Each specimen was tested for the presence of HSV-1 and HSV-2 using the illumigene assay, and results were compared to those of the enzyme-linked virus-inducible system (ELVIS) as the reference method. Overall, the illumigene assay demonstrated a sensitivity and specificity of 94.8% and 95.5%, respectively, for the detection of HSV-1. Detection of HSV-2 was similar, with a sensitivity of 98.9% and a specificity of 95.5%. Discrepant analysis was performed using an alternative molecular test (AmpliVue HSV1+2 assay; Quidel Molecular, San Diego, CA) on 91/99 specimens that were recorded as false positive (FP) or false negative (FN) compared to the reference method. In total, 57/78 (73%) FP and 9/13 (69%) FN illumigene results were supported by the AmpliVue result. The illumigene HSV 1&2 assay demonstrated high sensitivity and specificity to detect and differentiate HSV in clinical specimens and identified 57 additional specimens that were positive for HSV compared to culture. The use of LAMP eliminates the need for the cycling of temperatures and provides results in less than 60 min

Through the Lagrangian method, we find the influence of the quintessence matter on the time delay of null particle is presence by means of an additional integral term. When the quintessence field vanishes, it reduces to the usual Schwarzschild case naturally. Meanwhile, we also use the data of the Viking lander from the Mars and Cassini spacecraft to Saturn to constrain the quintessence field. For the Viking case, the field parameter {alpha} is under the order of 10{sup -9}. However, {alpha} is under 10{sup -18} for the Cassini case. (orig.)

    The Predictive Capability Maturity Model (PCMM) is an expert elicitation tool designed to characterize and communicate completeness of the approaches used for computational model definition, verification, validation, and uncertainty quantification associated for an intended application. The primary application of this tool at Sandia National Laboratories (SNL) has been for physics-based computational simulations in support of nuclear weapons applications. The two main goals of a PCMM evaluation are 1) the communication of computational simulation capability, accurately and transparently, and 2) the development of input for effective planning. As a result of the increasing importance of computational simulation to SNLs mission, the PCMM has evolved through multiple generations with the goal to provide more clarity, rigor, and completeness in its application. This report describes the approach used to develop the fourth generation of the PCMM.

    The presence of noise interference signal may cause problems in signal and image analysis; hence signal and image de-noising is often used as a preprocessing stage in many signal processing applications. In this paper, a new method is presented for image de-noising based on fourth order partial...... differential equations (PDEs) and wavelet transform. In the existing wavelet thresholding methods, the final noise reduced image has limited improvement. It is due to keeping the approximate coefficients of the image unchanged. These coefficients have the main information of the image. Since noise affects both...... indicate superiority of the proposed method over the existing waveletbased image de-noising, anisotropic diffusion, and wiener filtering techniques....

    Evans, M.W.

    1989-01-01

    The software-development process and its management are examined in a text intended for engineering managers and students of computer science. A unified concept based on the principle that software design is an engineering science rather than an art is applied, and a software engineering environment (SEE) analogous to an industrial plant is proposed. Chapters are devoted to the classical software environment, the history of software engineering, the evolution of the SEE, the fourth-generation SEE, the engineering process, software-data relationships, the SEE data base, data control in the SEE, software life cycles, information-system product assurance, business management and control, and automating and adapting the SEE. 143 refs.

    Who are we, and how do we relate to each other? Luciano Floridi, one of the leading figures in contemporary philosophy, argues that the explosive developments in Information and Communication Technologies (ICTs) is changing the answer to these fundamental human questions. As the boundaries between life online and offline break down, and we become seamlessly connected to each other and surrounded by smart, responsive objects, we are all becoming integrated into an ". Personas we adopt in social media, for example, feed into our 'real' lives so that we begin to live, as Floridi puts in, ". Following those led by Copernicus, Darwin, and Freud, this metaphysical shift represents nothing less than a fourth revolution.

  12. Black hole shadows in fourth-order conformal Weyl gravity

    CERN Document Server

    Mureika, Jonas R

    2016-01-01

    We calculate the characteristics of the "black hole shadow" for a rotating, neutral black hole in fourth-order conformal Weyl gravity. It is shown that the morphology is not significantly affected by the underlying framework, except for very large masses. Conformal gravity black hole shadows would also significantly differ from their general relativistic counterparts if the values of the main conformal gravity parameters, $\\gamma$ and $\\kappa$, were increased by several orders of magnitude. Such increased values for $\\gamma$ and $\\kappa$ are currently ruled out by gravitational phenomenology. Therefore, it is unlikely that these differences in black hole shadows will be detected in future observations, carried out by the Event Horizon Telescope or others such experiments.

  13. Cosmic Acceleration in a Model of Fourth Order Gravity

    Banerjee, Shreya; Singh, Tejinder P

    2015-01-01

    We investigate a fourth order model of gravity, having a free length parameter, and no cosmological constant or dark energy. We consider cosmological evolution of a flat Friedmann universe in this model for the case that the length parameter is of the order of present Hubble radius. By making a suitable choice for the present value of the Hubble parameter, and value of third derivative of the scale factor (the jerk) we find that the model can explain cosmic acceleration to the same degree of accuracy as the standard concordance model. If the free length parameter is assumed to be time-dependent, and of the order of the Hubble parameter of the corresponding epoch, the model can still explain cosmic acceleration, and provides a possible resolution of the cosmic coincidence problem. We also compare redshift drift in this model, with that in the standard model.

    1988-04-01

    During the fourth quarter of 1987, over 1700 samples which represent more than 5200 analyses and measurements were collected. More than ten real-time monitoring stations, which telemeter 10-minute averaged readings on radiation levels, total rainfall, flows, and water or air quality parameters around ORNL also reported data. In addition, three meteorological towers sent climatological data to a host computer every 15 minutes. Uranium concentrations on air filters located at stations near the Y-12 Plant (40, 45, and 46) were elevated above normal levels due to a release from the Y-12 Plant during October. Soil concentrations of /sup 234/U and /sup 238/U were significantly higher at the stations closest to the Y-12 Plant (40 and 45). /sup 235/U was significantly higher in soil at station 40 than at other stations. Cobalt/en dash/60 concentrations in Melton Branch water were significantly lower during this quarter than previous quarters because there was no discharge from the HFIR ponds. These ponds appear to be the source of most of the /sup 60/Co in Melton Branch. There were a total of 22 noncompliances associated with the NPDES permit during the fourth quarter of 1987. Fifteen of these were violations against a permit limit and the remainder were administrative failures in either collecting or analyzing required samples. Where appropriate, corrective actions or investigations are currently underway to address these noncompliances. Eight of the noncompliances were associated with high concentrations of total suspended solids at several of the Category I and II outfalls. Because no appreciable precipitation had occurred for over two weeks prior to the December sampling date, the samples taken would be expected to contain the first-flush of a 2 to 3 week accumulation of dust and other particulate matter from the areas drained by the outfalls.

    2004-01-01

    An example of interpolation by means of local field theories between the case of normal Kogut-Susskind fermions and the case of keeping just the fourth root of the Kogut-Susskind determinant is given. For the fourth root trick to be a valid approximation certain limits need to be smooth. The question about the validity of the fourth root trick is not resolved, only cast into a local field theoretical framework.

    Full Text Available The aim of this participant observation was to understand the efficacy of a modified International Baccalaureate Primary Years Program for fourth-graders at a public school with a large percentage of language and socioeconomically disadvantaged students. Data collection over a five-month period concentrated on teaching interactions including audio-recorded time samplings and observations of the art and regular classroom instruction, and interviews (formal and informal with students, teachers, and school principals in addition to photographs, classroom portfolios, and other artifacts. The analysis, coding, and triangulation of data aided in understanding the art specialist and classroom teachers’ roles and contributions to the Primary Years Program. A cooperative school environment paved the way for student self-confidence and motivation for learning through (1 opportunities for student choice and decision-making and (2 collaborative, inquiry-based, transdisciplinary, project-based learning. Regardless of demographics, transdiciplinary learning through the arts challenged and motivated students to think and make decisions in collaboration with others, using and valuing the expertise of peers. Regardless of student ethnicity or socioeconomic status, learners felt empowered and enthusiastic about attending school and gained knowledge through inquiry and project-based opportunities. This progressive ideology and practice has the potential to benefit diverse learners in 21st century education.

    2007-01-01

    Foreword Glacier Bay was established as a National Monument in 1925, in part to protect its unique character and natural beauty, but also to create a natural laboratory to examine evolution of the glacial landscape. Today, Glacier Bay National Park and Preserve is still a place of profound natural beauty and dynamic landscapes. It also remains a focal point for scientific research and includes continuing observations begun decades ago of glacial processes and terrestrial ecosystems. In recent years, research has focused on glacial-marine interactions and ecosystem processes that occur below the surface of the bay. In October 2004, Glacier Bay National Park convened the fourth in a series of science symposiums to provide an opportunity for researchers, managers, interpreters, educators, students and the general public to share knowledge about Glacier Bay. The Fourth Glacier Bay Science Symposium was held in Juneau, Alaska, rather than at the Park, reflecting a desire to maximize attendance and communication among a growing and diverse number of stakeholders interested in science in the park. More than 400 people attended the symposium. Participants provided 46 oral presentations and 41 posters covering a wide array of disciplines including geology, glaciology, oceanography, wildlife and fisheries biology, terrestrial and marine ecology, socio-cultural research and management issues. A panel discussion focused on the importance of connectivity in Glacier Bay research, and keynote speakers (Gary Davis and Terry Chapin) spoke of long-term monitoring and ecological processes. These proceedings include 56 papers from the symposium. A summary of the Glacier Bay Science Plan-itself a subject of a meeting during the symposium and the result of ongoing discussions between scientists and resource managers-also is provided. We hope these proceedings illustrate the diversity of completed and ongoing scientific studies, conducted within the Park. To this end, we invited all

    2003-03-01

    The Large Scale Test Facility (LSTF) is a full-height and 1/48 volumetrically scaled test facility of the Japan Atomic Energy Research Institute (JAERI) for system integral experiments simulating the thermal-hydraulic responses at full-pressure conditions of a 1100 MWe-class pressurized water reactor (PWR) during small break loss-of-coolant accidents (SBLOCAs) and other transients. The LSTF can also simulate well a next-generation type PWR such as the AP600 reactor. In the fifth phase of the Rig-of-Safety Assessment (ROSA-V) Program, eighty nine experiments have been conducted at the LSTF with the third simulated fuel assembly until June 2001, and five experiments have been conducted with the newly-installed fourth simulated fuel assembly until December 2002. In the ROSA-V program, various system integral experiments have been conducted to certify effectiveness of both accident management (AM) measures in beyond design basis accidents (BDBAs) and improved safety systems in the next-generation reactors. In addition, various separate-effect tests have been conducted to verify and develop computer codes and analytical models to predict non-homogeneous and multi-dimensional phenomena such as heat transfer across the steam generator U-tubes under the presence of non-condensable gases in both current and next-generation reactors. This report presents detailed information of the LSTF system with the third and fourth simulated fuel assemblies for the aid of experiment planning and analyses of experiment results. (author)

  3. Direct detection of fourth generation Majorana neutrino dark matter

    CERN Document Server

    Zhou, Yu-Feng

    2012-01-01

    Heavy stable fourth generation Majorana neutrinos contribute to a small fraction of the relic density of dark matter (DM) in the Universe. Due to its relatively strong coupling to the standard model particles, it can be probed by the current direct and indirect DM detection experiments even it is a subdominant component of the halo DM. We show that the current Xenon100 data constrain the mass of the stable Majorana neutrino to be greater than the mass of the top quark. The effective spin-independent cross section for the neutrino elastic scattering off nucleon is predicted to be $\\sim 1.5\\times 10^{-44} cm^2$, which is insensitive to the neutrino mass and mixing and can be reached by the direct DM detection experiments in the near future. In the same mass region the predicted effective spin-dependent cross section for the heavy neutrino scattering off proton is in the range of $2\\times 10^{-40} cm^2\\sim 2\\times 10^{-39} cm^2$, which is within the reach of the ongoing DM indirect search experiments. We demonst...

  4. Fourth-order partial differential equations for noise removal.

    Science.gov (United States)

    You, Y L; Kaveh, M

    2000-01-01

    A class of fourth-order partial differential equations (PDEs) are proposed to optimize the trade-off between noise removal and edge preservation. The time evolution of these PDEs seeks to minimize a cost functional which is an increasing function of the absolute value of the Laplacian of the image intensity function. Since the Laplacian of an image at a pixel is zero if the image is planar in its neighborhood, these PDEs attempt to remove noise and preserve edges by approximating an observed image with a piecewise planar image. Piecewise planar images look more natural than step images which anisotropic diffusion (second order PDEs) uses to approximate an observed image. So the proposed PDEs are able to avoid the blocky effects widely seen in images processed by anisotropic diffusion, while achieving the degree of noise removal and edge preservation comparable to anisotropic diffusion. Although both approaches seem to be comparable in removing speckles in the observed images, speckles are more visible in images processed by the proposed PDEs, because piecewise planar images are less likely to mask speckles than step images and anisotropic diffusion tends to generate multiple false edges. Speckles can be easily removed by simple algorithms such as the one presented in this paper.

    CERN is pleased to announce the fourth annual Beamline for Schools (BL4S) competition. Once again, in 2017, a fully equipped beamline will be made available at CERN for students. As in previous years, two teams will be invited to the Laboratory to execute the experiments they proposed in their applications. The 2017 competition is being made possible thanks to support from the Alcoa Foundation for the second consecutive year.   The competition is open to teams of high-school students aged 16 or older who, if they win, are invited (with two supervisors) to CERN to carry out their experiment. Teams must have at least five students but there is no upper limit to a team’s size (although just nine students per winning team will be invited to CERN). Teams may be composed of pupils from a single school, or from a number of schools working together. As science-loving mega-celebrity Will.I.Am told us: “If you’re interested in science, technology, engineering or ...

  6. Robust Optimization of Fourth Party Logistics Network Design under Disruptions

    2015-01-01

    Full Text Available The Fourth Party Logistics (4PL network faces disruptions of various sorts under the dynamic and complex environment. In order to explore the robustness of the network, the 4PL network design with consideration of random disruptions is studied. The purpose of the research is to construct a 4PL network that can provide satisfactory service to customers at a lower cost when disruptions strike. Based on the definition of β-robustness, a robust optimization model of 4PL network design under disruptions is established. Based on the NP-hard characteristic of the problem, the artificial fish swarm algorithm (AFSA and the genetic algorithm (GA are developed. The effectiveness of the algorithms is tested and compared by simulation examples. By comparing the optimal solutions of the 4PL network for different robustness level, it is indicated that the robust optimization model can evade the market risks effectively and save the cost in the maximum limit when it is applied to 4PL network design.

    2002-07-01

    Approximately seventy horizontal wells have been drilled in the course of three successful projects in the mature Algyo Field in Hungary since 1993. Recently, a fourth project has been initiated which includes the drilling of more than twenty new horizontal sections. These horizontal wells kick off existing abandoned wells along the thin oil rim that exists in two high permeability reservoirs with top gas and bottom water. The most significant difference between the two reservoirs is that one has water injection and the other has two layers with strong natural bottom water drive. The former geological and dynamic models for the hydrocarbon field in the Pannonian basin was rebuilt in order to handle the common aquifer of four reservoirs. Based on the new geology, reservoir simulation was used to study the reservoir behaviour, including the forthcoming period of gas cap production. The increase in reserves was matched with the production history to observe the movement of the water oil contact (WOC) with the production and drawdown rates in the future when the horizontal trajectories were planned. The reservoir management focused on maximising the long-term profit of the field by optimal production of the reserves, reducing gas and water coning and by the effective use of depleted gas reservoirs and existing vertical wells. Production rate and recovery was increased by reaching the by-passed hydrocarbon and by increasing the drainage area. 6 refs., 3 tabs., 14 figs.

    2010-01-01

    Results from the Fourth AIAA Drag Prediction Workshop (DPW-IV) are summarized. The workshop focused on the prediction of both absolute and differential drag levels for wing-body and wing-body-horizontal-tail configurations that are representative of transonic transport air- craft. Numerical calculations are performed using industry-relevant test cases that include lift- specific flight conditions, trimmed drag polars, downwash variations, dragrises and Reynolds- number effects. Drag, lift and pitching moment predictions from numerous Reynolds-Averaged Navier-Stokes computational fluid dynamics methods are presented. Solutions are performed on structured, unstructured and hybrid grid systems. The structured-grid sets include point- matched multi-block meshes and over-set grid systems. The unstructured and hybrid grid sets are comprised of tetrahedral, pyramid, prismatic, and hexahedral elements. Effort is made to provide a high-quality and parametrically consistent family of grids for each grid type about each configuration under study. The wing-body-horizontal families are comprised of a coarse, medium and fine grid; an optional extra-fine grid augments several of the grid families. These mesh sequences are utilized to determine asymptotic grid-convergence characteristics of the solution sets, and to estimate grid-converged absolute drag levels of the wing-body-horizontal configuration using Richardson extrapolation.

    2017-01-01

    Full Text Available In the Czech Republic, the concept of dyslexia is used as a global term for various developmental deficiencies relating to reading skills. The criteria used for dyslexia are not clear and intervention is solely focused on word reading training. Not much is known about the pattern and level of reading comprehension abilities among Czech readers. The study examines reading comprehension and its component skills (decoding and listening comprehension abilities in 32 Czech fourth-grade children with a formal diagnosis of dyslexia and their classmates (N=126. In decoding tests, the children with dyslexia surprisingly lagged behind most significantly in a task concerning speed and accuracy in context reading. Contrary to expectations, the children with dyslexia also showed inferiority in a listening comprehension task. In reading comprehension measures, in comparison to the typically developing readers, the children with dyslexia achieved the best results in a oral reading comprehension task. The results are discussed with respect to Czech counselling and educational practice and the need for changes in the current support system and terminology is stressed.

    The fourth United States Naval Observatory (USNO) CCD Astrograph Catalog, UCAC4 was released in August 2012 (double-sided DVD and CDS data center Vizier catalog I/322). It is the final release in this series and contains over 113 million objects; over 105 million of them with proper motions. UCAC4 is an updated version of UCAC3 with about the same number of stars also covering all-sky. Bugs were fixed, Schmidt plate survey data were avoided, and precise 5-band photometry were added. Astrograph observations have been supplemented for bright stars by FK6, Hipparcos and Tycho-2 data to compile a UCAC4 star catalog complete to about magnitude R = 16. Epoch 1998 to 2004 positions are obtained from observations with the 20 cm aperture USNO Astrograph's red lens, equipped with a 4k by 4k CCD. Mean positions and proper motions are derived by combining these observations with over 140 ground- and space-based catalogs, including Hipparcos/Tycho and the AC2000.2, as well as unpublished measures of over 5000 plates from ...

  11. EIA publication manual: Fourth edition. [Energy information manuals

    Energy Technology Data Exchange (ETDEWEB)

    Neef, C.A.

    1988-01-01

    This is the fourth edition of the Publications Manual. It was written to help the staff of the Energy Information Administration (EIA) who are involved in the production process to create and format uniform publications that not only provide information, but readily identify the agency. The manual reflects the substantial changes that have taken place to streamline methods of producing EIA publications over the past few years. Whereas the first edition, in 1979, was written for writers and typists which struggled with producing reports on manual typewriters, this report now reflects the increased use of automation in preparing most EIA publications. EIA has a fully automated photocomposition publishing system. Many of the style features discussed in this manual are automatically produced using EPIC/ICEF2. The need for format sheets and illustrations produced by graphic artists has been significantly reduced. However, the basic style has changed very little. EIA style continues to be based on the Government Printing Office Style Manual with some deviations tailored specifically for EIA.

  12. Fourth Data Challenge for the ALICE data acquisition system

    CERN Multimedia

    Maximilien Brice

    2003-01-01

    The ALICE experiment will study quark-gluon plasma using beams of heavy ions, such as those of lead. The particles in the beams will collide thousands of times per second in the detector and each collision will generate an event containing thousands of charged particles. Every second, the characteristics of tens of thousands of particles will have to be recorded. Thus, to be effective, the data acquisition system (DAQ) must meet extremely strict performance criteria. To this end, the ALICE Data Challenges entail step-by-step testing of the DAQ with existing equipment that is sufficiently close to the final equipment to provide a reliable indication of performance. During the fourth challenge, in 2002, a data acquisition rate of 1800 megabytes per second was achieved by using some thirty parallel-linked PCs running the specially developed DATE software. During the final week of tests in December 2002, the team also tested the Storage Tek linear magnetic tape drives. Their bandwidth is 30 megabytes per second a...

    2005-01-01

    Based on the {\\it dynamical} equivalence between higher order gravity and scalar-tensor gravity the PPN-limit of fourth order gravity is discussed. We exploit this analogy developing a fourth order gravity version of the Eddington PPN-parameters. As a result, Solar System experiments can be reconciled with higher order gravity, if physical constraints descending from experiments are fulfilled.

    Computing has revolutionized the biological sciences over the past several decades, such that virtually all contemporary research in molecular biology, biochemistry, and other biosciences utilizes computer programs. The computational advances have come on many fronts, spurred by fundamental developments in hardware, software, and algorithms. These advances have influenced, and even engendered, a phenomenal array of bioscience fields, including molecular evolution and bioinformatics; genome-, proteome-, transcriptome- and metabolome-wide experimental studies; structural genomics; and atomistic simulations of cellular-scale molecular assemblies as large as ribosomes and intact viruses. In short, much of post-genomic biology is increasingly becoming a form of computational biology. The ability to design and write computer programs is among the most indispensable skills that a modern researcher can cultivate. Python has become a popular programming language in the biosciences, largely because (i) its straightforward semantics and clean syntax make it a readily accessible first language; (ii) it is expressive and well-suited to object-oriented programming, as well as other modern paradigms; and (iii) the many available libraries and third-party toolkits extend the functionality of the core language into virtually every biological domain (sequence and structure analyses, phylogenomics, workflow management systems, etc.). This primer offers a basic introduction to coding, via Python, and it includes concrete examples and exercises to illustrate the language's usage and capabilities; the main text culminates with a final project in structural bioinformatics. A suite of Supplemental Chapters is also provided. Starting with basic concepts, such as that of a "variable," the Chapters methodically advance the reader to the point of writing a graphical user interface to compute the Hamming distance between two DNA sequences.

    PURPOSE To devise a cost-effective guide for the evaluation of fourth nerve palsies (FNP). METHODS A review of the pertinent English language literature was performed to devise a guide for the evaluation (including neuroimaging) of FNP. The authors report a retrospective review of imaging studies performed on 206 patients with FNP. RESULTS The literature was used to develop the imaging guide. In the retrospective chart review of 206 patients from two tertiary care centers, 28 patients (13.6%) underwent a computed tomography scan and/or a magnetic resonance scan. Of these patients, five had associated neurological symptoms (non-isolated), one was traumatic, five were congenital, four were vasculopathic, eleven were non-vasculopathic, and two were progressive. Following the recommendations of the imaging guide, the five isolated congenital FNP and the four isolated vasculopathic FNP would not have undergone neuroimaging studies. The total costs of these neuroimaging studies in these nine patients were 19,000 dollars. Four patients in the retrospective review with associated neurological deficits (non-isolated) should have undergone neuroimaging according to the guide, but did not. CONCLUSIONS Although the evaluation of FNP can be difficult, the decision to order neuroimaging can be improved by using an imaging guide. An imaging guide for the evaluation of FNP may allow more appropriate and cost-effective imaging of these patients. Isolated congenital, old traumatic, or vasculopathic FNP do not require neuroimaging studies. Patients with non-isolated FNP should have directed neuroimaging studies based upon the results of clinical examination.

  11. Older people and digital disengagement: a fourth digital divide?

    Science.gov (United States)

    Olphert, Wendy; Damodaran, Leela

    2013-01-01

    Digital technologies are becoming more pervasive in all areas of society. Enabling everyone to have access and capability to use the Internet and associated digital technologies, summed up in the term 'digital inclusion', is seen to have wide-ranging benefits to the individual, to the economy and to society. For older people, being digitally included can help them to maintain their independence, social connectedness and sense of worth in the face of declining health or limited capabilities, as well as also offering new opportunities to improve their quality of life. At present however, access to the technology and to the benefits is not equally distributed either between or within nations, and older people tend to be on the 'wrong' side of what is termed the 'digital divide'. Governments globally are developing strategies to promote digital inclusion and indeed Internet uptake is increasing steadily, including amongst older people. However, such strategies have focussed on getting people online, and there appears to be an assumption that once someone is online they will remain 'digitally engaged'. In fact statistics show that some users give up using the Internet, and there is emerging evidence that older people are more vulnerable to the factors which can lead to this outcome. The authors see this phenomenon as a potential but largely unrecognised 'fourth digital divide' which has serious implications for social inclusion. The objectives of this article are (a) to raise awareness of the phenomenon of digital disengagement by considering some of the emerging evidence, (b) to explore some of the potential implications of not recognising and therefore not addressing the needs of the digitally disengaged older population, and (c) to reveal the prevailing gap in knowledge which future research should address.

    This is the fourth annual progress report on the UK Fuel Poverty Strategy. It presents positive news over figures and funding, growing evidence of increased engagement in tackling fuel poverty and a snapshot of the UK-wide situation. All of this appears alongside a realistic assessment of the impact of energy price rises and the outlook for the future, both in the medium and long-term. The report provides an update on the actions taken over the last twelve months. The report offers the first opportunity to look at the new phase of the Warm Front Scheme in England, and to explore what the additional funding will mean for the future. Progress and developments in the Schemes across the devolved nations are also considered. The fuel poverty figures for 2004 are presented. The number of vulnerable households in fuel poverty in England in 2004 remained at 1.0 million. This figure is down from four million in 1996.The overall number of households in fuel poverty in England also remained at a similar level of 1.2 million. The UK-wide figures remained broadly the same, with two million households in fuel poverty overall and one and a half million of those in the vulnerable category. The results of detailed modelling work to determine what the implications of recent energy price rises will be for the 2010 target in England are given. Finally, this report is accompanied by a series of internet-based annexes which provide more detail on the progress made in tackling fuel poverty by both Government and industry. These include more in-depth statistics on the demographic, geographic and socio-economic breakdowns of fuel poverty and a broader outline of the actions taken in this area by energy suppliers across the UK.

    Full Text Available Four long-spined sea urchin species in the genus Diadema are known to occur around the Japanese Archipelago. Three species (D. savignyi, D. setosum, and D. paucispinum are widely distributed in the Indo-Pacific Ocean. The fourth species was detected by DNA analysis among samples originally collected as D. savignyi or D. setosum in Japan and the Marshall Islands and tentatively designated as Diadema-sp, remaining an undescribed species. We analyzed nucleotide sequences of the cytochrome oxidase I (COI gene in the "D. savignyi-like" samples, and found all 17 individuals collected in the mainland of Japan (Sagami Bay and Kyushu to be Diadema-sp, but all nine in the Ryukyu Archipelago (Okinawa and Ishigaki Islands to be D. savignyi, with large nucleotide sequence difference between them (11.0%±1.7 SE. Diadema-sp and D. savignyi shared Y-shaped blue lines of iridophores along the interambulacrals, but individuals of Diadema-sp typically exhibited a conspicuous white streak at the fork of the Y-shaped blue iridophore lines, while this feature was absent in D. savignyi. Also, the central axis of the Y-shaped blue lines of iridophores was approximately twice as long as the V-component in D. savignyi whereas it was of similar length in Diadema-sp. Two parallel lines were observed to constitute the central axis of the Y-shaped blue lines in both species, but these were considerably narrower in Diadema-sp. Despite marked morphological and genetic differences, it appears that Diadema-sp has been mis-identified as D. savignyi for more than half a century.

    Full Text Available The development of information and communication technologies has resulted in revolutionary changes, which seem to continue in economy, society and many areas of life. The most important resource of the new social structure emerging as a result of technologies is information, thus the development of human capacity related to the use of information is extremely important. It may not be easy for parents and teachers to face the fact that the majority of their children/pupils know more about cyberspace than themselves. But are primary school pupils really better versed? Does digital literacy indeed automatically evolve? Does the use of the internet by all means improve children’s academic performance? In our current study we are researching how primary school pupils in the easternmost part of Hungary use the internet, and what effects it has on their studies. We would also like to emphasize the role of teachers working at the lower grades of the primary school in the formation of pupils’ digital literacy. In 2013 190 fourth-grader primary school pupils of eight schools filled in our questionnaire. Based on the data negative correlation was found between the time spent on web browsing and the academic average. Analysis of variance also revealed that those pupils have a higher academic average whose parents regularly check the purpose of their children’s internet usage. Our research results showed that the pupils who use the internet and the library equally to search for new information have a higher academic average compared to those pupils who only make use of either the traditional or the online option only. The most important result of the research is that in the case of adequate parental or professional (teacher control internet may have fruitful effects on pupils’ studies, but in the lack of such control the opposite is more likely.

  15. Preface to the first monograph: The Fourth Psychiatric Revolution

    2004-05-01

    Full Text Available At present, psychiatry is in the midst of a fourth revolution. The first revolution was the so-called Moral Treatment which involved the activism of Phileppe Pinel (1745-1826 and William Tuke (1732-1819, as also the efforts of Dorothea Dix (1802-1887. This resulted in destigmatization of the lunatic label which had earlier meant treating the insane in a dehumanizing manner e.g.. chaining them to walls, displaying them for money etc. It resulted in the transition to custodial care and the opening of mental hospitals. The second psychiatric revolution was the Mental Hygiene Movement heralded by the eye­opening works of Elizabeth Packard (Modern Persecution or Insane Hospital Unveiled and Clifford Beers (1876-1943; A Mind That Found Itself which was furthered by, amongst others, pioneers like Adolf Meyer (1866-1950 and William James (1842-1910. This was followed by the third Psychiatric revolution, that of the Community Psychiatry Movement. This involved community participation, removal of restrictions, comprehensive set of services multi-disciplinary in nature, active consumer participation, mental health consultancy and preventive measures. This well intentioned grand movement had its problems, as all such grand movement must indeed have. It became the fountain­source of a fresh crop of difficulties related to transinstitutionalization in boarding and halfway houses, with increased rates of hospital admission, and the 'revolving door syndrome'. Moreover, it lead to an ominous rise in contact between the criminal justice system and the mentally ill as they moved more freely in the community.Today, we are in the midst of a silent by strong fourth revolution. Firstly, this revolution reiterates its strong linkage with the mainstream of medicine. Secondly, it bases itself on strong, empirical findings based on rigorous methodological studies, mainly biological. The major paradigm shift of contemporary psychiatry is towards methodological rigour on

    2008-01-01

    The fourth annual validity study of the Health Education Systems, Inc. (HESI) Exit Exam was designed to examine not only the accuracy of the examination in predicting NCLEX success but also the degree of risk for failure of the licensure examination associated with specific scoring intervals. A descriptive comparative design was used to examine the data provided by schools of nursing regarding students' NCLEX outcomes in the 1999-2000 academic year. As in the 3 previous studies, the examination was found to be a highly accurate predictor of NCLEX success (98.46%). Each scoring interval was significantly different from each of the other scoring intervals (P = .001). In fact, for the combined group of registered nurse and practical nurse students, the percentage of students who failed the NCLEX more than doubled with each successively lower scoring interval. These findings provide the information faculties needed to make evidence-based decisions regarding students' risks for NCLEX failure. Additionally, frequency data were obtained from this survey regarding the use of the examination as a benchmark for progression and remediation, and these findings may also be useful to faculties that are considering establishing such programs.

  20. First and Fourth-Year Student’s Perceptions about Importance of Nursing Care Behaviors: Socialization toward Caring

    Directory of Open Access Journals (Sweden)

    Vahid Zamanzadeh

    2014-06-01

    Full Text Available Introduction: The essence of professional nursing is caring and so, nursing education must make caring as a significant part of their curricula. In this regard, little research exists about how nursing students perceive caring. The aim of this study is to investigate the nursing students' perception toward caring and thus, the impact of socialization process on their perception of caring will be determined. Methods: A cross-sectional study was done among all first and fourth-year nursing students (n=230 in Tabriz and Urmia faculties of nursing, 2012. Data were collected using Larson’s Caring Questionnaire that assessed the importance of nursing care behaviors (n=50 in six dimensions: "being accessible", "explains and facilitates", "comforts", "anticipates", "trusting relationship" and "monitors and follows through". Results: The importance of caring behaviors was evaluated by the first and fourth-year nursing students in moderate to high level and also, the both groups considered higher ranks for "monitors and follows through" and "being accessible" and lower ranks for "anticipates" and "trusting relationships". The fourth-year students only ranked "explains and facilitates" higher than the first-year students, but the "comforts" dimension is not differed significantly between groups.Conclusion: The findings demonstrated that nursing education in this study has not likely succeeded in producing intended changes in the nursing students' perceptions. It is recommended to exactly find the perceptual changes or in principle the professional socialization process of nursing students, more research using longitudinal designs be conducted to examine the differences in students' perceptions of caring upon entering and completing the nursing program.

    The Democratic People's Republic of Korea has conducted its fourth underground nuclear explosions on 06.01.2016 at 01:30 (UTC). The explosion was clearly detected and located by the seismic network of the International Monitoring System (IMS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBT). Additional seismic stations of international earthquake monitoring networks at regional distances, which are not part of the IMS, are used to precisely estimate the epicenter of the event in the North Hamgyong province (41.38°N / 129.05°E). It is located in the area of the North Korean Punggye-ri nuclear test site, where the verified nuclear tests from 2006, 2009, and 2013 were conducted as well. The analysis of the recorded seismic signals provides the evidence, that the event was originated by an explosive source. The amplitudes as well as the spectral characteristics of the signals were examined. Furthermore, the similarity of the signals with those from the three former nuclear tests suggests very similar source type. The seismograms at the 8,200 km distant IMS station GERES in Germany, for example, show the same P phase signal for all four explosions, differing in the amplitude only. The comparison of the measured amplitudes results in the increasing magnitude with the chronology of the explosions from 2006 (mb 4.2), 2009 (mb 4.8) until 2013 (mb 5.1), whereas the explosion in 2016 had approximately the same magnitude as that one three years before. Derived from the magnitude, a yield of 14 kt TNT equivalents was estimated for both explosions in 2013 and 2016; in 2006 and 2009 yields were 0.7 kt and 5.4 kt, respectively. However, a large inherent uncertainty for these values has to be taken into account. The estimation of the absolute yield of the explosions depends very much on the local geological situation and the degree of decoupling of the explosive from the surrounding rock. Due to the missing corresponding information, reliable magnitude-yield estimation for the

    The master equation for a charged harmonic oscillator coupled to an electromagnetic reservoir is investigated up to fourth order in the interaction strength by using Krylov averaging method. The interaction is in the velocity-coupling form and includes a diamagnetic term. Exact analytical expressions for the second-, the third-, and the fourth-order contributions to mass renormalization, decay constant, normal and anomalous diffusion coefficients are obtained for the blackbody type environment. It is found that, generally, the third- and the fourth-order contributions have opposite signs when their magnitudes are comparable to that of the second-order one.

    2009-01-01

    Fourth-order stream-function methods are proposed for the time dependent, incom-pressible Navier-Stokes and Bonssinesq equations. Wide difference stencils are used instead of compact ones and the boundary terms are handled by extrapolating the stream-function values inside the computational domain to grid points outside, up to fourth-order in the no-slip condition. Formal error analysis is done for a simple model problem, showing that this extrapolation introduces numerical boundary layers at fifth-order in the stream-function. The fourth-order convergence in velocity of the proposed method for the full problem is shown numerically.

    Using Krylov averaging method, we have derived a fourth-order master equation for a charged harmonic oscillator weakly coupled to an electromagnetic field. Interaction is assumed to be of velocity coupling type which also takes into account the diagmagnetic term. Exact analytical expressions have been obtained for the second, the third and the fourth-order corrections to the diffusion and the drift terms of the master equation. We examined the validity range of the second order master equation in terms of the coupling constant and the bath cutoff frequency and found that for the most values of those parameters, the contribution from the third and the fourth order terms have opposite signs and cancel each other. Inclusion of the third and the fourth-order terms is found to not change the structure of the master equation. Bolu, Turkey.

    Introduction: We prospectively investigated the relationship between newborn male circumcision (NMC) and second to fourth digit ratio with penile length. Methods: As participants for our study, we identified already circumcised young patients who visited our hospital for urological treatment. The age at which the circumcision had been done was assessed. The patients’ height and weight were measured. Second to fourth digit ratio was calculated by measuring the second and fourth digit lengths. The flaccid and erectile penile lengths were measured from the base of the penis to the tip of the glans in standing position. Results: A total of 248 patients were included in our study. In univariate analysis, height, second to fourth digit ratio, flaccid penile length, and age of circumcision were associated with erectile penile length. Among these variables, second to fourth digit ratio, flaccid penile length, and age of circumcision were significant predictive factors for erectile penile length in multivariate analysis. The subjects were divided into two groups, including 72 patients in the NMC group and 176 patients in the non-NMC group. No significant difference was found in height, weight, and second to fourth digit ratio between both groups. However, flaccid (p<0.001) and erectile (p=0.001) penile lengths were shorter in the NMC group than in the non-NMC group. Conclusions: Despite the small number of subjects, this study shows that NMC was associated with shorter penile length. Second to fourth digit ratio, flaccid penile length, and age of circumcision were also significant predictive factors for erectile penile length. Further multicentre studies with larger number of subjects and biochemical analyses are needed for potential clinical applicability. PMID:27695583

    2006-04-01

    The formulation of a quantum theory of gravity seems to be the unavoidable endpoint of modern theoretical physics. Yet the quantum description of the gravitational field remains elusive. The year 2005 marks the tenth anniversary of the First Meeting on Constrained Dynamics and Quantum Gravity, held in Dubna (Russia) due to the efforts of Alexandre T. Filippov (JINR, Dubna) and Vittorio de Alfaro (University of Torino, Italy). At the heart of this initiative was the desire for an international forum where the status and perspectives of research in quantum gravity could be discussed from the broader viewpoint of modern gauge field theories. Since the Dubna meeting, an increasing number of scientists has joined this quest. Progress was reported in two other conferences in this series: in Santa Margherita Ligure (Italy) in 1996 and in Villasimius (Sardinia, Italy) in 1999. After a few years of ``working silence'' the time was now mature for a new gathering. The Fourth Meeting on Constrained Dynamics and Quantum Gravity (QG05) was held in Cala Gonone (Sardinia, Italy) from Monday 12th to Friday 16th September 2005. Surrounded by beautiful scenery, 100 scientists from 23 countries working in field theory, general relativity and related areas discussed the latest developments in the quantum treatment of gravitational systems. The QG05 edition covered many of the issues that had been addressed in the previous meetings and new interesting developments in the field, such as brane world models, large extra dimensions, analogue models of gravity, non-commutative techniques etc. The format of the meeting was similar to the previous ones. The programme consisted of invited plenary talks and parallel sessions on cosmology, quantum gravity, strings and phenomenology, gauge theories and quantisation and black holes. A major goal was to bring together senior scientists and younger people at the beginning of their scientific career. We were able to give financial support to both

    Relatively few studies have been performed that analyze the morphology of the choroid plexus of the fourth ventricle. Due to the importance of this tissue as a landmark on imaging and during surgical intervention of the fourth ventricle, the authors performed a cadaveric study to better characterize this important structure. The choroid plexus of the fourth ventricle of 60 formalin fixed adult human brains was examined and measured. The horizontal distance from the midline to the lateral most point of the protruding tip of the horizontal limbs was measured. In the majority of the 60 brain specimens, right and left horizontal limbs of the choroid plexus were seen extending from the midline and protruding out of their respective lateral apertures of the fourth ventricle and into the subarachnoid space. However, on 3.3% of sides, there was absence of an extension into the foramen of Luschka and in one specimen, this lack of extension into the foramen of Luschka was bilateral. On two sides, there was discontinuity between the midline choroid plexus and the tuft of choroid just outside the foramen of Luschka. For specimens in which the choroid plexus did protrude through the foramen of Luschka (96.7%), these tufts were located anterior to the flocculus and inferolateral to the facial/vestibulocochlear nerve complex and posterosuperior to the glossopharyngeal/vagal/accessory complex. A thorough understanding of the normal and variant anatomy of the fourth ventricular choroid plexus is necessary for those who operate in, or interpret imaging of, this region.

    This special issue consists of 11 original papers that elaborate on work presented at the Fourth Annual q-bio Conference on Cellular Information Processing, which was held on the campus of St John's College in Santa Fe, New Mexico, USA, 11-14 August 2010. Now in its fourth year, the q-bio conference has changed considerably over time. It is now well established and a major event in systems biology. The 2010 conference saw attendees from all continents (except Antarctica!) sharing novel results and participating in lively discussions at both the oral and poster sessions. The conference was oversubscribed and grew to 27 contributed talks, 16 poster spotlights and 137 contributed posters. We deliberately decreased the number of invited speakers to 21 to leave more space for contributed presentations, and the attendee feedback confirmed that the choice was a success. Although the q-bio conference has grown and matured, it has remained true to the original goal of being an intimate and dynamic event that brings together modeling, theory and quantitative experimentation for the study of cell regulation and information processing. Funded in part by a grant from NIGMS and by DOE funds through the Los Alamos National Laboratory Directed Research and Development program, the conference has continued to exhibit youth and vigor by attracting (and partially supporting) over 100 undergraduate, graduate and postdoctoral researchers. The associated q-bio summer school, which precedes the conference each year, further emphasizes the development of junior scientists and makes q-bio a singular event in its impact on the future of quantitative biology. In addition to an increased international presence, the conference has notably diversified its demographic representation within the USA, including increased participation from the southeastern corner of the country.

    Full Text Available Background: Different surgical approaches have been described in the past to treat a trapped fourth ventricle (TFV but, unfortunately, these techniques showed a high rate of dysfunction and complications. During the last 10 years the development of neuroendoscopy has dramatically changed the outcome of these patients. Materials and Methods: We conducted a retrospective evaluation of the safety, effectiveness, and long-term outcome of endoscopic aqueductoplasty and stent placement, performed in 18 consecutive patients with symptomatic TFV through a trans-fourth ventricle approach between 1994 and 2010. Thirteen patients underwent endoscopic aqueductoplasty and stent placement and 5 patients underwent aqueductoplasty alone using a tailored suboccipital approach through the foramen of Magendie in prone or sitting position. Results: The mean age of the patients at the time of surgery was 15.2 years. All patients but 3 had a supratentorial ventriculoperitoneal shunt. Fifteen patients presented with slit supratentorial ventricles. At a mean followup of 90.8 months all patients experienced a stable clinical improvement. Only two complications were observed: A transient diplopia due to dysconjugate eye movements in one patient and a transient trochlear palsy in another one. Conclusions: Our experience and the literature review suggest that endoscopic trans-fourth ventricle aqueductoplasty and stent placement is a minimally invasive, safe, and effective technique for the treatment of TFV and should be strongly recommended, especially in patients with supratentorial slit ventricles.

  1. Entropy Diagnostics for Fourth Order Partial Differential Equations in Conservation Form

    2008-09-01

    Full Text Available The entropy evolution behaviour of a partial differential equation (PDE in conservation form, may be readily discerned from the sign of the local source term of Shannon information density. This can be easily used as a diagnostic tool to predict smoothing and non-smoothing properties, as well as positivity of solutions with conserved mass. The familiar fourth order diffusion equations arising in applications do not have increasing Shannon entropy. However, we obtain a new class of nonlinear fourth order diffusion equations that do indeed have this property. These equations also exhibit smoothing properties and they maintain positivity. The counter-intuitive behaviour of fourth order diffusion, observed to occur or not occur on an apparently ad hoc basis, can be predicted from an easily calculated entropy production rate. This is uniquely defined only after a technical definition of the irreducible source term of a reaction diffusion equation.

    An expression for the fourth moment in zero-field NMR has been analytically derived and numerically evaluated for a rigid cubic lattice. Model simulations have been performed to calculate the second moment, the fourth moment, the ratio of the fourth moment to the square of the second moment, and the width of the resonance line for a crystal and a polycrystalline material in high-field as well as in zero-field NMR. The simulation results allow us to draw two conclusions: (1) zero-field NMR gives sharper and better defined spectra than the high-field NMR and (2) the ratio of the high- to zero-field resonance line-widths is 4 for a crystal, whereas it is 11 for a polycrystalline material.

    1988-05-01

    The influence of a magnetic field on the propagation of fourth sound in superfluid /sup 3/He is studied. The field and temperature dependences of the average superfluid density /anti rho//sub s///rho/ and fourth sound Q are measured. The field dependence of /anti rho//sub s///rho/ is very different in a porous medium than predicted by Ginzburg-Landau theory applied to bulk liquid. In particular, a magnetic suppression of /anti rho//sub s///rho/ is observed in the temperature and pressure ranges corresponding to the A phase in bulk liquid. There is strong evidence of a magnetic suppression of T/sub c/ itself. The measured /anti rho//sub s///rho/ has a slight history dependence in a magnetic field, but none in zero field. The fourth-sound Q values are compared to the theoretical work of Smith, Jensen, and Wolfle. Quantitative confirmation of their work is problematic.

    We present a non-perturbative determination of the upper and lower Higgs boson mass bounds with a heavy fourth generation of quarks from numerical lattice computations in a chirally symmetric Higgs-Yukawa model. We find that the upper bound only moderately rises with the quark mass while the lower bound increases significantly, providing additional constraints on the existence of a straight-forward fourth quark generation. We examine the stability of the lower bound under the addition of a higher dimensional operator to the scalar field potential using perturbation theory, demonstrating that it is not significantly altered for small values of the coupling of this operator. For a Higgs boson mass of {proportional_to}125 GeV we find that the maximum value of the fourth generation quark mass is {proportional_to}300 GeV, which is already in conflict with bounds from direct searches.

  5. On the third- and fourth-order constants of incompressible isotropic elasticity.

    Destrade, Michel; Ogden, Raymond W

    2010-12-01

    Consider the constitutive law for an isotropic elastic solid with the strain-energy function expanded up to the fourth order in the strain and the stress up to the third order in the strain. The stress-strain relation can then be inverted to give the strain in terms of the stress with a view to considering the incompressible limit. For this purpose, use of the logarithmic strain tensor is of particular value. It enables the limiting values of all nine fourth-order elastic constants in the incompressible limit to be evaluated precisely and rigorously. In particular, it is explained why the three constants of fourth-order incompressible elasticity μ, Ā, and D are of the same order of magnitude. Several examples of application of the results follow, including determination of the acoustoelastic coefficients in incompressible solids and the limiting values of the coefficients of nonlinearity for elastic wave propagation.

  6. On the nature of the fourth generation neutrino and its implications

    2012-01-01

    We consider the neutrino sector of a Standard Model with four generations. While the three light neutrinos can obtain their masses from a variety of mechanisms with or without new neutral fermions, fourth-generation neutrinos need at least one new relatively light right-handed neutrino. If lepton number is not conserved this neutrino must have a Majorana mass term whose size depends on the underlying mechanism for lepton number violation. Majorana masses for the fourth generation neutrinos induce relative large two-loop contributions to the light neutrino masses which could be even larger than the cosmological bounds. This sets strong limits on the mass parameters and mixings of the fourth generation neutrinos.

  7. Treatment of Complications after Distraction Osteogenesis for Brachymetatarsia of the Fourth Metatarsal

    Summary: Congenital brachymetatarsia most commonly involves the fourth ray and may be combined with metacarpal shortening. Numerous reports have demonstrated the usefulness of gradual lengthening of the metatarsals. However, very few studies have investigated methods of recovering the lost regenerative bone. The patient was a 16-year-old girl with bilateral brachymetatarsia of the fourth metatarsal. After a long consolidation period after gradual lengthening of the fourth metatarsal by 20 mm, the patient had an hourglass-shaped regenerated bone. Therefore, we grafted a bioabsorbable hydroxyapatite and collagen composite. Six months after the surgery, well-regenerated bone could be recognized on radiographic evaluation and was resistant to refracture. Callus distraction is a method that aims to avoid donor site morbidity. The strength of artificial bone is often a problem. Bioabsorbable hydroxyapatite and collagen composite compensates for the lack of regenerated bone and distraction gap and prevents refracture, thus preventing complications after metatarsal distraction.

    Full Text Available Background. To our knowledge, this is the sixth reported case in the literature of fourth ventricular schwannoma. The etiology and natural history of intraventricular schwannomas is not well understood. A thorough review of potential etiopathogenic mechanisms is provided in this case report. Case Description. A 69-year-old man presented with an incidentally found fourth ventricular tumor during an evaluation for generalized weakness, gait instability, and memory disturbance. Magnetic resonance imaging (MRI revealed a heterogeneously enhancing lesion in the fourth ventricle. A suboccipital craniotomy was performed to resect the lesion. Histopathological examination confirmed the diagnosis of schwannoma (WHO grade I. Conclusions. Schwannomas should be considered in the differential diagnosis of intraventricular tumors. Although the embryologic origins may be different from nerve sheath-derived schwannomas, the histologic, clinical, and natural history appear identical and thus should be managed similarly.

    Partial differential equation (PDE) has become one of the important topics in mathematics and is widely used in various fields. It can be used for image denoising in the image analysis field. In this paper, a fourth-order PDE is discussed and implemented as a denoising method on digital images. The fourth-order PDE is solved computationally using finite difference approach and then implemented on a set of digital radiographic images with welding defects. The performance of the discretized model is evaluated using Peak Signal to Noise Ratio (PSNR). Simulation is carried out on the discretized model on different level of Gaussian noise in order to get the maximum PSNR value. The convergence criteria chosen to determine the number of iterations required is measured based on the highest PSNR value. Results obtained show that the fourth-order PDE model produced promising results as an image denoising tool compared with median filter.

    Noise reduction is one of the largest problems and biggest difficulties involved in electronic speckle pattern interferometry (ESPI). Although the second-order PDEs denoising method is a useful tool of noise reduction for the ESPI fringe patterns, its main drawback is that the second-order PDE model does not remove impulse noise, a 3×3 mean window filter is generally needed to improve the fringes. For overcome this main drawback, in this paper we apply the fourth-order PDE denoising model to the computer-simulated and experimentally obtained ESPI fringe, respectively. In both tests, the fourth-order PDE denoising model clearly outperforms the second-order PDE denoising model. Experimental results have confirmed that the fourth-order PDE denoising model is capable of removing noise in ESPI fringe images effectively.

  12. Turn left for Murmansk: ‘Fourth World’ transculturalism and its cultural ecological framing

    Directory of Open Access Journals (Sweden)

    Patrick Dillon

    2014-04-01

    Full Text Available In this paper we review briefly histories and ideologies underlying multiculturalism in Nordic countries, highlighting tensions between integrationist and inclusive approaches. We propose a cultural ecological framework through which we discuss the possibility of a transculturalism based on Fourth World engagement with the environment. Cultural ecology is about the reciprocal interactions and transactions between people and their environments. The Fourth World is a circum-global, pan-arctic region which includes the northern parts of some Nordic countries. We argue that whether or not there is a distinctively Nordic version of multiculturalism, Nordic countries have access to Fourth World ways of engaging with the environment which transcend notions of inter- and multiculturalism and the ideological tensions associated with them.

    2003-07-01

    Full Text Available We describe the magnetic resonance imaging (MRI signal characteristics of isolated (solitary lesion intra fourth ventricular cysticercus cyst in 4 patients who clinically presented with obstructive hydrocephalus. All patients had routine MRI sequences (T1, T2, & proton density-weighted imaging, Fluid Attenuation Inversion Recovery (FLAIR, and post-gadolinium imaging followed by cerebrospinal fluid (CSF flow study. It revealed a CSF signal intensity (on all pulse sequences, intra fourth ventricular cyst with a nidus (scolex, and wall enhancement. On T1-weighted and FLAIR images, the cyst wall and nidus (scolex were seen in 3 cases, which were not seen in other routine sequences. The CSF flow study showed the intraluminal nature of the cyst. The MRI features suspected a cysticercus cyst, and per-operative findings and histopathological examination confirmed the diagnosis. The review of literature of the intra fourth ventricular cyst is briefly discussed.

    2013-01-01

    This investigation deals with the effects of slip, magnetic field, and non-Newtonian flow parameters on the flow and heat transfer of an incompressible, electrically conducting fourth-grade fluid past an infinite porous plate. The heat transfer analysis is carried out for two heating processes. The system of highly non-linear differential equations is solved by the shooting method with the fourth-order Runge-Kutta method for moderate values of the parameters. The effective Broyden technique is adopted in order to improve the initial guesses and to satisfy the boundary conditions at infinity. An exceptional cross-over is obtained in the velocity profile in the presence of slip. The fourth-grade fluid parameter is found to increase the momentum boundary layer thickness, whereas the slip parameter substantially decreases it. Similarly, the non-Newtonian fluid parameters and the slip have opposite effects on the thermal boundary layer thickness.

    2004-03-01

    We developed a novel approach for fenestration of the trapped fourth ventricle utilizing the superior medullary velum (valve of Vieussens). Trapped fourth ventricles, which are seen often in the pediatric hydrocephalic population, are troublesome entities surgically. A right burr hole was carried out in 10 adult cadavers with no gross intracranial pathology and the superior medullary velum was fenestrated to the quadrigeminal cistern with the aid of an endoscope. This technique was carried out easily in all cadaveric specimens. With endoscopy, no vascular insult was appreciated either before or after fenestration of the superior medullary velum. These preliminary findings demonstrate that fenestration of the superior medullary velum may provide a good alternative to the present therapy of shunting trapped fourth ventricles, a therapy wrought with complications.

    Aim: To present the neuroradiological and clinical findings of fourth-ventricular meningiomas to increase awareness of this entity. Materials and methods: The computed tomography (CT; n = 5), magnetic resonance imaging (MRI; n = 9) features and clinical presentations of 10 patients with pathologically documented fourth-ventricular meningiomas were retrospectively analysed. Results: All tumours appeared as well-demarcated masses in the fourth ventricle at CT and MRI. The tumour shape was round in eight cases (80%) and irregular in two cases (20%). The CT images of five cases showed predominantly isoattenuation in three cases and high attenuation in two cases, with a mean attenuation value of 52 HU. In addition, calcifications were seen in three cases. At MRI, nine masses were isointense (n = 6) or hypointense (n = 3) to grey matter on T1-weighted images and mildly hyperintense (n = 4), isointense (n = 3), hypointense (n = 1), and of mixed signal intensity (n = 1) on T2-weighted and fluid-attenuated inversion recovery (FLAIR) images. Signal voids were visible in two cases. Enhancement after injection of contrast material was marked homogeneous (n = 5) or heterogeneous (n = 5) on CT or T1-weighted images. Three tumours had mild peritumoural oedema. Three tumours were associated with obstructive hydrocephalus. The pathological subtype of the 10 meningiomas was fibromatous (n = 5), atypical (n = 2), and one each of transitional, psammomatous, and clear-cell type. Conclusion: Although fourth-ventricular meningioma is quite rare, it should be considered in differential diagnosis of neoplasms within the fourth ventricle. The relatively typical radiological appearance, combined the age and sex of patients, can suggest the diagnosis of fourth-ventricular meningioma.

    2014-06-01

    Fourth-Order Rayleigh-Schrodinger Perturbation Theory (VPT4) is applied to a series of small molecules. The quality of results have been shown to be heavily dependent on the quality of the quintic and sextic force constants used and that numerical sextic force constants converge poorly and are unreliable for VPT4. Using analytic Hartree-Fock force constants, it is shown that these analytic higher-order force constants are comparable to corresponding force constants from numerical calculations at a higher level of theory. Calculations show that analytic Hartree-Fock sextic force constants are reliable and can provide good results with Fourth-Order Rayleigh-Schrodinger Perturbation Theory.

    The solution of the problem on linearization of fourth-order equations by means of point transformations is presented here. We show that all fourth-order equations that are linearizable by point transformations are contained in the class of equations which is linear in the third-order derivative. We provide the linearization test and describe the procedure for obtaining the linearizing transformations as well as the linearized equation. For ordinary differential equations of order greater than 4 we obtain necessary conditions, which separate all linearizable equations into two classes.

    2006-01-01

    Using symplectic integrator propagator, a three-dimensional fourth-order symplectic finite difference time domain (SFDTD) method is studied, which is of the fourth order in both the time and space domains. The method is nondissipative and can save more memory compared with the traditional FDTD method. The total field and scattered field (TF-SF) technique is derived for the SFDTD method to provide the incident wave source conditions. The bistatic radar cross section (RCS) of a dielectric sphere is computed by using the SFDTD method for the first time. Numerical results suggest that the SFDTD algorithm acquires better stability and accuracy compared with the traditional FDTD method.

    2010-07-01

    This paper presents an edge-preserving fourth order partial differential equation (PDE) for image restoration derived from a new surface-based energy functional. The corresponding fourth order PDE can preserve edges and avoid the staircase effect. The proposed model contains a function of gradient norm as an edge detector, which controls the diffusion speed according to the local structure of the image and preserves more details. Denoising results are given and we have also compared our method with some related PDE models.

  1. The Fourth Age of Political Communication: Democratic decay or the rise of phronetic political communication?

    2016-11-01

    Full Text Available The ‘fourth age’ of political communication is emerging. In the fourth age the logics of media and digitization shapes the public sphere, because algorithms and polarized drama increasingly determine what we become aware of in digital and mass media. The result may very well be a less informed public sphere. The emerging class of policy professionals has the opportunity to mix the logics of mediatization and digitization. While such a mix may very well lead to democratic decay, based on elitism, it may also hold fruitful potentials for a more democratic and ethical type of political communication, called phronetic political communication.

    Aiming at the problem of target detection in passive radar in correlated noise surroundings, we present a new estimation of the Complex ambiguity function based on Downsampled fourth-order statistics (CAF-DFOS) to improve the performances of the traditional Complex ambiguity function based on Second-order statistics (CAF-SOS) and the existing Complex ambiguity function based on Fourth-order statistics (CAF-FOS). Both the theory and the simulations show that in the aspect of Gaussian noise suppression, its performance is better than the CAF-SOS algorithm; in the aspect of estimate variance and frequency resolution, its performance is better than the CAF-FOS algorithm.

    The effect of fourth-order coherence on ultrafast modulation spectroscopy (UMS) with phase-conjugation geome try (PCUMS) in a cascade three-level system is investigated using chaotic and phase-diffusion models. It has been found that the modulation terms of the beat signal depend on the second-order coherence function, and different stochastic models of the laser field affect only the fourth-order coherence function. The difference between the PCUMS and UMS is discussed from a physical viewpoint.

    In 2008, the Atmospheric Radiation Measurement (ARM) Program and the Climate Change Prediction Program (CCPP) have been asked to produce joint science metrics. For CCPP, the metrics will deal with a decade-long control simulation using geodesic grid-coupled climate model. For ARM, the metrics will deal with observations associated with the 2006 deployment of the ARM Mobile Facility (AMF) to Niamey, Niger. Specifically, ARM has been asked to deliver data products for Niamey that describe cloud, aerosol, and dust properties. The first quarter milestone was the initial formulation of the algorithm for retrieval of these properties. The second quarter milestone included the time series of ARM-retrieved cloud properties and a year-long CCPP control simulation. The third quarter milestone included the time series of ARM-retrieved aerosol optical depth and a three-year CCPP control simulation. This final fourth quarter milestone includes the time-series of aerosol and dust properties and a decade-long CCPP control simulation.

  6. Exploring the development of fourth graders' environmental identity through participation in a semi-formal nature club

    Brock, Ryan J.

    Nature deficit, where disconnections occur between children and nature have come to the forefront of environmental education in recent years. This study explored how fourth graders in an after-school Nature Club developed or strengthened their environmental identity, thus decreasing nature deficit. Through a program that utilized semi-formal instruction, both classroom learning and direct experiences with nature, took place over a nine week period of time. Six children were followed as qualitative data was collected and analyzed for themes that would reveal how adolescent children in the developmental stage of concrete operations developed environmental identity. The results indicate that all students strengthened their environmental identity when social aspects were embedded. Students who entered Nature Club with low environmental identity required more direct experiences with nature while those with higher environmental identity required a combination of reflective components along with nature experiences. Based upon this study, the nine-week program which combined formal and non-formal means of learning was able to strengthen environmental identity in each of the participants. A strong theme of social learning, not explicitly identified in the literature was found. Additionally, and most importantly, findings also indicate that educators, both formal and non-formal, who teach environmental education and seek to strengthen environmental identity for adolescents for early interventions need to understand the development of environmental identity in concrete operational learners at a theoretical level.

    The United States Department of Energy’s Next Generation Nuclear Plant (NGNP) Advanced Gas Reactor (AGR) Fuel Development and Qualification Program is irradiating up to seven low enriched uranium (LEU) tri-isotopic (TRISO) particle fuel (in compact form) experiments in the Advanced Test Reactor (ATR) located at the Idaho National Laboratory (INL). These irradiations and fuel development are being accomplished to support development of the next generation reactors in the United States. The experiments will be irradiated over the next several years to demonstrate and qualify new TRISO coated particle fuel for use in high temperature gas reactors. The goals of the experiments are to provide irradiation performance data to support fuel process development, to qualify fuel for normal operating conditions, to support development and validation of fuel performance and fission product transport models and codes, and to provide irradiated fuel and materials for post irradiation examination (PIE) and safety testing. The experiments, which will each consist of several independent capsules, will be irradiated in an inert sweep gas atmosphere with individual on-line temperature monitoring and control of each capsule. The sweep gas will also have on-line fission product monitoring on its effluent to track performance of the fuel in each individual capsule during irradiation. The first experiment (designated AGR-1) started irradiation in December 2006 and was completed in November 2009. The second experiment (AGR-2) started irradiation in June 2010 and is currently scheduled to be completed in September 2013. The third and fourth experiments have been combined into a single experiment designated (AGR-3/4), which started its irradiation in December 2011 and is currently scheduled to be completed in April 2014. Since the purpose of this combined experiment is to provide data on fission product migration and retention in the NGNP reactor, the design of this experiment is

    The papers in this proceedings were selected from the 63 presentations given at the Fourth Biennial Conference on Research in National Parks in California. The overall theme for this meeting was a recurring one: “The Integration of Research into National Park Service Resource Management Decisions.” The conference was held at the University of California, Davis, on 10-12 September 1991 and was sponsored by the National Park Service Cooperative Park Studies Unit and the Institute of Ecology at the University of California, Davis. This proceedings highlights a variety of research and resource management efforts to improve the stewardship of our most treasured landscapes. In the future, it will become increasingly more important for federal and state agencies, university scientists and students, and the public to cooperate fully to improve the quantity and quality of science and resource management programs in units of the National Park System. As many of the papers in this proceedings attest, we must look beyond the political boundaries of protected landscapes to incorporate entire ecosystems. Competing resource uses inside and outside parklands must be reexamined to weave a common thread of biological conservation. As scientists, our studies must bridge the gap from plots to landscapes and from landscapes to regions. Our studies must built on information from species and populations to ecosystems and the processes that influence them. The papers in this proceedings are modest but important contribution to those ideals. Each paper represents original research and has been peer-reviewed. Many agencies, institutions, and individuals contributed in the development of this product. In the planning stages, National Park Service Western Region scientists provided advice and assistance in structuring the conference format. University of California, Davis, graduate students, directed by Sharon Lynch, assisted with logistics at the meeting, and provided general assistance

    Full Text Available The national policy in 2004 aimed to develop the curriculum in Science andTechnology classes and to keep up with the change sand progress happening. Given the developed curriculum of Science andTechnology, it can be seen that the constructivist learning theory was adopted (Gömleksiz & Bulut, 2005. Students in the fourth grade the first encounter with the curriculum of Science and Technology. In this regard, students learn the concepts of the fourth grade program correct and complete construction is extremely important the correct the construction of science concepts in their minds. In this context, the new curriculum is based on science and technology skills and knowledge required by the constructivist approach is of great importance for fourth grade teachers. Therefore, based on the constructivist approach teachers teaching methods and techniques are required to have sufficient knowledge and skills to practice (Gömleksiz & Bulut, 2005. The constructivist philosophy recommends the radical changes related to the arrangement of the class and realization of the education. However, the studies showed that the constructivist approach present in the curriculum was not administered in the clasroom environment, and that the teaching was maintained through teacher-centric applications. (Bozyılmaz& Bağcı-Kılıç, 2005; Saylan & Yurdakul, 2005; Yaşar, Gültekin, Türkkan, Yıldız, & Girmen, 2005. Correspondingly, Anagün, Yalçınoğluand Ersoy (2012 found that only one-third of the fiften ones adopted the constructivist approach but only two of them put the approach in to practice. This study aimed to describe the present situation and the problems encountered in terms of the objectives, activities and assessment based on the constructivist approach in science and technology classes in the fourth grades. The findings obtained are thought to shedlight on curriculum development. The methodology of this study is descriptive. The classes related were

    2013-01-01

    Full Text Available How to make the individual get the reasonable and practical profit among the fourth party logistics supply chain coalition system is still a question for further study. Considering the characteristics of the fourth party logistics supply chain coalition, this paper combines Shapley Value with Distribution according to Contribution, two methods in the application, and then adjusts the profit allocated to each member reasonably based on the actual coalition situation named improved weighted Shapley Value model. In this paper, we first analyze the fourth party logistics supply chain coalition profit allocation models, the classical Shapley value method. Then, we analyze the weight of individual enterprise in the coalition by the analytic hierarchy process. To each enterprise, the weight is determined by the investment risks, information divulging risks, and failure risks. Finally, the numerical study shows that the profit allocation method improved weighted Shapley value model is relatively rational and practical. Thus, the proposed combined model is a useful profit allocation mechanism for the fourth party logistics supply chain coalition that the contribution and risks are fully considered.

    Markov, Yu A; Bondarenko, A I

    2016-01-01

    Within the framework of the Bhabha-Madhavarao formalism, a consistent approach to the derivation of a system of the fourth order wave equations for the description of a spin-$\\frac{3}{2}$ particle is suggested. For this purpose an additional algebraic object, the so-called $q$-commutator ($q$ is a primitive fourth root of unity) and a new set of matrices $\\eta_{\\mu}$, instead of the original matrices $\\beta_{\\mu}$ of the Bhabha-Madhavarao algebra, are introduced. It is shown that in terms of the $\\eta_{\\mu}$ matrices we have succeeded in reducing a procedure of the construction of fourth root of the fourth order wave operator to a few simple algebraic transformations and to some operation of the passage to the limit $z \\rightarrow q$, where $z$ is some (complex) deformation parameter entering into the definition of the $\\eta$-matrices. In addition, a set of the matrices ${\\cal P}_{1/2}$ and ${\\cal P}_{3/2}^{(\\pm)}(q)$ possessing the properties of projectors is introduced. These operators project the matrices ...

  5. Socio-Political Exclusion as Bane of Nigeria’s Fourth Republic

    Directory of Open Access Journals (Sweden)

    Okpanachi Odiji

    2015-04-01

    Full Text Available This work focuses on socio-political exclusion which characterises the Nigerian fourth republic and the damage it has brought to the system. It is structured to address the conceptualizations of Socio-political exclusion, Democracy, and the Nigerian Fourth Republic; observed acts of socio-political exclusion in the Nigeria’s Fourth Republic and the repercussion of this exclusion on the nation. Exploiting the Marxist social conflict theory and drawing information from events which have been unfolding as depicted in the news media and other authoritative sources, the discourse observes that, the myriad of problems inherent in contemporary Nigeria sprang out of the unlevelled political playing field designed and handed down by the ruling class made up of retired military and their civilian cronies. It concludes therefore that unless the political contest field is redesigned to accommodate those that are currently excluded from both socio political and economic activities; the ensuing crises might bring the fourth republic just like its predecessors to an undesirable end.

  11. The origin of the lower fourth molar in canids, inferred by individual variation

    Directory of Open Access Journals (Sweden)

    Masakazu Asahara

    2016-11-01

    Full Text Available Background An increase in tooth number is an exception during mammalian evolution. The acquisition of the lower fourth molar in the bat-eared fox (Otocyon megalotis, Canidae, Carnivora, Mammalia is one example; however, its developmental origin is not clear. In some canids (Canidae, individual variation exist as supernumerary molar M4. This study focuses on the acquisition of the lower fourth molar in canids and proposes that the inhibitory cascade model can explain its origin. Methods Occlusal view projected area of lower molars was determined from 740 mandibles obtained from Canis latrans, Nyctereutes procyonoides, and Urocyon cinereoargenteus museum specimens. For each molar, relative sizes of molars (M2/M1 and M3/M1 scores affected by inhibition/activation dynamics during development, were compared between individuals with and without supernumerary molar (M4. Results Possession of a supernumerary molar was associated with significantly larger M2/M1 score in Canis latrans, M3/M1 score in Nyctereutes procyonoides, and M2/M1 and M3/M1 scores in Urocyon cinereoargenteus compared to individuals of these species that lacked supernumerary molars. Discussion We propose that, in canids, the supernumerary fourth molar is attributable to reduced inhibition and greater activation during molar development. In the bat-eared fox, altered inhibition and activation dynamics of dental development during omnivorous-insectivorous adaptation may be a contributing factor in the origin of the lower fourth molar.

    Chen, Guoqiang; Xiao, Qing; Zheng, Jiaping; Wu, Jinting; Ao, Qiang; Liu, Yunsheng

    2015-01-01

    In this study, we try to present our experience of transaqueductal removal of the fourth ventricular neurocysticercosis (FVNCC) with a flexible neuroendoscope. Three cases of the fourth ventricular cysticercosis were transaqueductally removed with FUJINON EB-270P flexible neuroendoscope through a frontal precoronal burr hole. The diagnosis was established on imaging and confirmed on histology in all of the cases. Complete excision of cysts in the fourth ventricle was performed in all cases with no significant intraoperative or postoperative complications. The shunt and the string-of-beads multiple cysts in the basal cistern were removed simultaneously through the orificium fistulae of the third ventricle floor with the flexible neuroendoscope. Satisfactory postoperative CSF flow around foramen magnum was detected by cine phase-contrast magnetic resonance imaging. All of the patients were asymptomatic, with an average follow-up of 6 months. The whole ventricular system can be explored easily with electrical flexible neuroendoscope. Endoscopic transaqueductal removal of the fourth ventricular cysticercosis with a flexible neuroendoscope should be recommended as the optimal choice of the disease due to its minimal invasion, fewer complications, shorter length of stay and cheaper treatment costs.

    2016-02-01

    Second-to-fourth digit ratio is a widely investigated sexually dimorphic morphological trait in human studies and could reliably indicate the prenatal steroid environment. Conducting manipulative experiments to test this hypothesis comes up against ethical limits in humans. However, oviparous tetrapods may be excellent models to experimentally investigate the effects of prenatal steroids on offspring second-to-fourth digit ratio. In this field study, we injected collared flycatcher ( Ficedula albicollis) eggs with physiological doses of testosterone. Fledglings from eggs with elevated yolk testosterone, regardless of their sex, had longer second digits on their left feet than controls, while the fourth digit did not differ between groups. Therefore, second-to-fourth digit ratio was higher in the testosterone-injected group, but only on the left foot. This is the first study which shows experimentally that early testosterone exposure can affect second-to-fourth digit ratio in a wild population of a passerine bird.

    The Clean Energy Ministerial (CEM) is a high-level global forum to share best practices and promote policies and programs that advance clean energy technologies and accelerate the transition to a global clean energy economy. The CEM works to increase energy efficiency, expand clean energy supply, and enhance clean energy access worldwide. To achieve these goals, the CEM pursues a three-part strategy that includes high-level policy dialogue, technical cooperation, and engagement with the private sector and other stakeholders. Each year, energy ministers and other high-level delegates from the 23 participating CEM governments come together to discuss clean energy, review clean energy progress, and identify tangible next steps to accelerate the clean energy transition. The U.S. Department of Energy, which played a crucial role in launching the CEM, hosted the first annual meeting of energy ministers in Washington, DC, in June 2010. The United Arab Emirates hosted the second Clean Energy Ministerial in 2011, and the United Kingdom hosted the third Clean Energy Ministerial in 2012. In April 2013, India hosted the fourth Clean Energy Ministerial (CEM4) in New Delhi. Key insights from CEM4 are summarized in the report. It captures the ideas and recommendations of the government and private sector leaders who participated in the discussions on six discussion topics: reducing soft costs of solar PV; energy management systems; renewables policy and finance; clean vehicle adoption; mini-grid development; and power systems in emerging economies.

    We study the effect of a potential fourth fermion generation on the upper and lower Higgs boson mass bounds. This investigation is based on the numerical evaluation of a chirally invariant lattice Higgs-Yukawa model emulating the same Higgs-fermion coupling structure as in the Higgs sector of the electroweak Standard Model. In particular, the considered model obeys a Ginsparg-Wilson version of the underlying $SU(2)_L\\times U(1)_Y$ symmetry, being a global symmetry here due to the neglection of gauge fields in this model. We present our results on the modification of the upper and lower Higgs boson mass bounds induced by the presence of a hypothetical very heavy fourth quark doublet. Finally, we compare these findings to the standard scenario of three fermion generations.

    A study of bound states of the fourth-generation quarks in the range of 500–700 GeV is presented, where the binding energies are expected to be mainly of Yukawa origin, with QCD subdominant. Near degeneracy of their masses exhibits a new `isospin'. The production of a colour- octet, isosinglet vector meson via $q\\bar{q} → g$ is the most interesting. Its leading decay modes are $_{8}^{±} W^{\\mp}$, $_{8}^{0} Z^{0}$, and constituent quark decay, with $q\\bar{q}$ and $t\\bar{t'}$ and $b\\bar{b'}$ subdominant. The colour octet, isovector pseudoscalar 8 meson decays via constituent quark decay, or to $W g$. This work calls for more detailed study of fourth-generation phenomena at LHC.

    Guo, H; Wu, K; Guo, Hanying; Li, Jianming; Wu, Ke

    1994-01-01

    Based upon a first principle, the generalized gauge principle, we construct a general model with G_L\\times G'_R \\times Z_2 gauge symmetry, where Z_2=\\pi_4(G_L) is the fourth homotopy group of the gauge group G_L, by means of the non-commutative differential geometry and reformulate the Weinberg-Salam model and the standard model with the Higgs field being a gauge field on the fourth homotopy group of their gauge groups. We show that in this approach not only the Higgs field is automatically introduced on the equal footing with ordinary Yang-Mills gauge potentials and there are no extra constraints among the parameters at the tree level but also it most importantly is stable against quantum correlation.

  16. A FOURTH ORDER DERIVATIVE-FREE OPERATOR MARCHING METHOD FOR HELMHOLTZ EQUATION IN WAVEGUIDES

    Institute of Scientific and Technical Information of China (English)

    Ya Yan Lu

    2007-01-01

    A fourth-order operator marching method for the Helmholtz equation in a waveguide is developed in this paper. It is derived from a new fourth-order exponential integrator for linear evolution equations. The method improves the second-order accuracy associated with the widely used step-wise coupled mode method where the waveguide is approximated by segments that are uniform in the propagation direction. The Helmholtz equation is solved using a one-way reformulation based on the Dirichlet-to-Neumann map. An alternative version closely related to the coupled mode method is also given. Numerical results clearly indicate that the method is more accurate than the coupled mode method while the required computing effort is nearly the same.

  18. Symplectic fourth-order maps for the collisional N-body problem

    CERN Document Server

    Dehnen, Walter

    2016-01-01

    We study analytically and experimentally certain symplectic and time-reversible N-body integrators which employ a Kepler solver for each pair-wise interaction, including the method of Hernandez & Bertschinger (2015). Owing to the Kepler solver, these methods treat close two-body interactions correctly, while close three-body encounters contribute to the truncation error at second order and above. The second-order errors can be corrected to obtain a fourth-order scheme with little computational overhead. We generalise this map to an integrator which employs a Kepler solver only for selected interactions and yet retains fourth-order accuracy without backward steps. In this case, however, two-body encounters not treated via a Kepler solver contribute to the truncation error.

    2010-05-01

    Acousto-elasticity is concerned with the propagation of small-amplitude waves in deformed solids. Results previously established for the incremental elastodynamics of exact non-linear elasticity are useful for the determination of third- and fourth-order elastic constants, especially in the case of incompressible isotropic soft solids, where the expressions are particularly simple. Specifically, it is simply a matter of expanding the expression for ρv(2), where ρ is the mass density and v the wave speed, in terms of the elongation e of a block subject to a uniaxial tension. The analysis shows that in the resulting expression: ρv(2) = a+be+ce(2), say, a depends linearly on μ; b on μ and A; and c on μ, A, and D, the respective second-, third, and fourth-order constants of incompressible elasticity, for bulk shear waves and for surface waves.

We compare different approaches to derive this result, namely, the ladder operators approach, the isomonodromy deformations approach and combining the Toda system for the recurrence coefficients with a discrete equation. We also discuss a relation between the recurrence coefficients for the Freud weight and the semi-classical Laguerre weight and show how it arises from the B\\"acklund transformation of the fourth Painlev\\'e equation.

    2010-01-01

    Full Text Available While the Fourth World Conservation Congress (WCC was effective in bringing together different participants to discuss climate change, the discussion of potential mitigation mechanisms was dominated by the Reducing Emissions for Deforestation and Degradation (REDD initiative, to the exclusion of other possibilities, including Non-timber Forest Products (NTFP-there was a notable lack of venues for discussing the relevance of NTFP projects for biodiversity conservation, climate change mitigation and poverty alleviation. This paper contrasts the treatment of NTFP and REDD at the WCC and discusses how the exclusion of NTFP from these discussions will probably affect its inclusion in the conservation agenda and the future design and funding of conservation projects. The paper also shares some ideas on unexplored complementarities between NTFP and REDD for climate change mitigation, showing that an opportunity was lost at the Fourth WCC for promoting NTFP as an additional market-based approach to conservation.

    Intraventricular hemorrhage (IVH) is a neurological urgency with a high mortality and unfavorable prognosis.Fast removal of intraventricular blood should be considered as a priority.The current treatments of IVH mainly focus on external ventricular drain and endoscopic aspiration,but neither way can remove the blood in the fourth ventricle easily and relieve the compression of brainstem.Here we report a unique procedure to solve this problem.A 41-year-old male patient who had suffered sudden attack of headache and disturbance of consciousness for 2 h was diagnosed as having high density lesion in thewhole ventricular system by computed tomographic (CT) imaging.An emergent bilateral ventriculopuncture and intraventricular hematoma removal under non-line-of-sight was performed immediately;the catheter was extended to the fourth ventricle to maximally remove the hematoma.Postoperative CT scan demonstrated total removal of IVH and no sign of extra brain damage.

  6. On the joint distribution of surface slopes for the fourth order nonlinear random sea waves

    Institute of Scientific and Technical Information of China (English)

    张书文; 孙孚; 管长龙

    1999-01-01

    Based upon the nonlinear model of Longuet-Higgins the joint distribution of wave surface slopes is theoretically investigated. It is shown that in the fourth order approximation, the distribution is given by truncated Gram-Charlier series. The types of wave-wave coupling interactions are related to the order of approximation to nonlinearity of sea surface, which eventually defines the truncated term of the Gram-Charlier series. For each order approximation, the coefficients in the series are modified comparatively to the corresponding ones for the previous order approximation. If the nonlinear effect of the kurtosis is considered, the wave surface must be as accurate at least as to the third order approximation, and with regard to skewness, the wave surface must be as accurate at least as to the fourth order approximation.

  9. Exploring a fourth dimension: spirituality as a resource for the couple therapist.

    Anderson, D A; Worthen, D

    1997-01-01

    This article explores ways in which the therapist's own spirituality can serve as a resource in couple therapy. Spirituality is defined as subjective engagement with a fourth, transcendent dimension of human experience. This engagement enhances human life and evokes corresponding behavior. Spiritually based therapy may be influenced by three assumptions: that God or a Divine Being exists, that human-kind yearns innately for connection with this Being, and that this Being is interested in humans and acts upon and within their relationships to promote beneficial change. In therapy these assumptions affect how the therapist listens and responds throughout sessions. The authors incorporate a case example illustrating the application of this fourth dimension in couple therapy.

    Full Text Available This paper explores the effect of patriarchal-construct on political development in Nigeria’s fourth republic. It compares representation matrices by gender in both executive and legislative organs of government with a view to revealing wide gap that exists between the male and female political office holders since May 29, 1999. The paper relies extensively on secondary source of data collection and descriptive analytical method. The paper submits that it is the men construct of political power with less consideration of the women folk that accounts for low representation in Nigeria’s fourth republic. It recommends a gender-reconstruct of political development that encourages women’s participation and representation at primary and general elections; as well as strict adherence to democratic ideals and principles of electoral process.

  11. Up to fourth virial coefficients from simple and efficient internal-coordinate sampling: application to neon.

    2012-07-01

    A simple and efficient internal-coordinate importance sampling protocol for the Monte Carlo computation of (up to fourth-order) virial coefficients ̅B(n) of atomic systems is proposed. The key feature is a multivariate sampling distribution that mimics the product structure of the dominating pairwise-additive parts of the ̅B(n). This scheme is shown to be competitive over routine numerical methods and, as a proof of principle, applied to neon: The second, third, and fourth virial coefficients of neon as well as equation-of-state data are computed from ab initio two- and three-body potentials; four-body contributions are found to be insignificant. Kirkwood-Wigner quantum corrections to first order are found to be crucial to the observed agreement with recent ab initio and experimental reference data sets but are likely inadequate at very low temperatures.

    Influence of the fourth generation, if ever exists, on the experimentallymeasurable quantities such as invariant dilepton mass distribution, leptonforward-backward asymmetry, and the ratio (Gamma_L/Gamma_T) of the decay widthswhen K* meson is longitudinally and transversally polarized, is studied. Usingthe experimental results on the branching ratios for the (B -> X_s) gamma andsemileptonic (B -> X_c l nu) decays, the two possible solutions of the 4x4Cabibbo-Kobayashi-Maskawa factor (V_{t's} V_{t^'b}) are obtained as a functionof the t'-quark mass. It is observed that the results for the above-mentionedphysical quantities are essentially different from the standard modelpredictions only for one solution of the CKM factor. In this case theabove-mentioned physical quantities can serve as efficient tools in search ofthe fourth generation. The other solution yields almost identical results withthe SM.

    Full Text Available Subependymomas are a rare subtype of ependymomas, slow growing WHO grade I tumors that develop either intracranial from the subependymal glial precursor cells layer of the ventricles or intramedullary. These tumors originate in the undifferentiated Subependymal layer of cells that can become either ependymocytes or astrocytes. Most of the subependymomas are located inside the fourth ventricle (50-60%. We reviewed the case of a 40 years old woman with a giant solid cystic fourth ventricle ependymoma. The patient underwent total resection of the tumor through a subociipital transvermian approach. We discussed the characteristics of these benign tumors and reviewed the literature on this subject and concluded that total resection is the treatment of choice for symptomatic Subependymomas localized in posterior fossa.

    Full Text Available We investigate the existence of positive or a negative solution of several classes of four-point boundary-value problems for fourth-order ordinary differential equations. Although these problems do not always admit a (positive Green's function, the obtained solution is still of definite sign. Furthermore, we prove the existence of an entire continuum of solutions. Our technique relies on the continuum property (connectedness and compactness of the solutions funnel (Kneser's Theorem, combined with the corresponding vector field.

    Full Text Available A deferred correction method is utilized to increase the order of spatial accuracy of the Crank-Nicolson scheme for the numerical solution of the one-dimensional heat equation. The fourth-order methods proposed are the easier development and can be solved by using Thomas algorithms. The stability analysis and numerical experiments have been limited to one-dimensional heat-conducting problems with Dirichlet boundary conditions and initial data.

    We reconsider the cosmic string perturbative solution to the classical fourth-order gravity field equations, obtained in Ref.\\cite{CLA94}, and we obtain that static, cylindricaly symmetric gauge cosmic strings, with constant energy density, can contain only \\beta-terms in the first order corrections to the interior gravitational field, while the exact exterior solution is a conical spacetime with deficit angle D=8\\pi\\mu.
