    2001-01-01

    This paper presents the status of analyses on three Rocket Based Combined Cycle (RBCC) configurations underway in the Applied Fluid Dynamics Analysis Group (TD64). TD64 is performing computational fluid dynamics (CFD) analysis on a Penn State RBCC test rig, the proposed Draco axisymmetric RBCC engine and the Trailblazer engine. The intent of the analysis on the Penn State test rig is to benchmark the Finite Difference Navier Stokes (FDNS) code for ejector mode fluid dynamics. The Draco analysis was a trade study to determine the ejector mode performance as a function of three engine design variables. The Trailblazer analysis is to evaluate the nozzle performance in scramjet mode. Results to date of each analysis are presented.

    The Norwegian Mapping Authority (NMA) has during the last few years had a close cooperation with Norwegian Defence Research Establishment (FFI) in the analysis of space geodetic data using the GEOSAT software. In 2012 NMA has taken over the full responsibility for the GEOSAT software. This implies that FFI stopped being an IVS Associate Analysis Center in 2012. NMA has been an IVS Associate Analysis Center since 28 October 2010. NMA's contributions to the IVS as an Analysis Centers focus primarily on routine production of session-by-session unconstrained and consistent normal equations by GEOSAT as input to the IVS combined solution. After the recent improvements, we expect that VLBI results produced with GEOSAT will be consistent with results from the other VLBI Analysis Centers to a satisfactory level.

    Rudin, Walter

    2011-01-01

    In the late 1950s, many of the more refined aspects of Fourier analysis were transferred from their original settings (the unit circle, the integers, the real line) to arbitrary locally compact abelian (LCA) groups. Rudin's book, published in 1962, was the first to give a systematic account of these developments and has come to be regarded as a classic in the field. The basic facts concerning Fourier analysis and the structure of LCA groups are proved in the opening chapters, in order to make the treatment relatively self-contained.

    We give the center of the elliptic quantum group in general cases. Based on the dynamical Yang-Baxter relation and the fusion method, we prove that the center commutes with all generators of the elliptic quantum group. Then for a kind of assumed form of these generators, we find that the coefficients of these generators form a new type of closed algebra. We also give the center for the algebra.

    Full Text Available Background: Out of hospital cardiac arrest is a devastating event and is associated with poor outcomes; however, therapeutic hypothermia (TH is a novel treatment which may improve neurological outcome and decrease mortality. Despite this, TH is not uniformly implemented across Coronary Care and Intensive Care Units in Canada. Objective: The purpose of this study was to compare cerebral recovery and mortality rates between patients in our Coronary Care Unit who received TH with a historical control group. Materials and Methods: A retrospective chart review was performed of patients admitted to a tertiary care center with out-of-hospital cardiac arrest. Twenty patients who were admitted and cooled after December 2006 were compared with 29 noncooled patients admitted in the 5 years prior as a historical control group. The primary outcomes of interest were in-hospital mortality and neurological outcome. Results: Eleven of 20 (11/20, 55% patients who were cooled as per protocol survived to hospital discharge, all having a good neurological outcome. Eleven of 29 (11/29, 38% noncooled patients survived to hospital discharge (Odds Ratio: 0.50, 95% CI: 0.16- 1.60, P=0.26. Eleven of 20 patients who were cooled had a good neurological outcome (CPS I-II, 11/20, 55%, versus 7 of 29 (7/29, 24% of noncooled patients (Odds ratio: 3.84, 95% CI: 1.13- 13.1, P=0.03. One hundred percent (11/11 of survivors in the cooled group had a good neurological outcome. Conclusion: In our center, the use of TH in out-of-hospital cardiac arrest survivors was associated with improved neurological outcome.

    2013-01-01

    Until the Shuttle Atlantis' final landing on July 21, 2011, Kennedy Space Center (KSC) served as NASA's main spaceport, which is a launch and landing facility for rockets and spacecraft that are attempting to enter orbit. Many of the facilities at KSC were created to assist the Shuttle Program. One of the most important and used facilities is the Shuttle Landing Facility (SLF), This was the main landing area for the return of the shuttle after her mission in space. · However, the SLF has also been used for a number of other projects including straight-line testing by Gibbs Racing, weather data collection by NOAA, and an airfield for the KSC helicopters. This runway is three miles long with control tower at midfield and a fire department located at the end in care of an emergency. This facility, which was part of the great space race, will continue to be used for historical events as Kennedy begins to commercialize its facilities. KSC continues to be an important spaceport to the government, and it will transform into an important spaceport for the commercial industry as well. During my internship at KSC's Center Planning and Development Directorate, I had the opportunity to be a part of the negotiation team working on the agreement for Space Florida to control the Shuttle Landing Facility. This gave me the opportunity to learn about all the changes that are occurring here at Kennedy Space Center. Through various meetings, I discovered the Master Plan and its focus is to transform the existing facilities that were primarily used for the Shuttle Program, to support government operations and commercial flights in the future. This. idea is also in a new strategic business plan and completion of a space industry market analysis. All of these different documentations were brought to my attention and I. saw how they came together in the discussions of transitioning the SLF to a commercial operator, Space Florida. After attending meetings and partaking in discussions for

    We discuss theories with the exceptional centerless gauge group G(2), paying attention to confinement and the pattern of chiral symmetry breaking. Exploiting the Higgs mechanism to break the symmetry down to SU(3), we also present how the familiar features of confinement and chiral symmetry breaking of SU(3) gauge theories reemerge. G(2) gauge theories show up as an unusual theoretical framework to study SU(3) gauge theories without the ``luxury'' of a center.

    2007-10-01

    Group cohesion is considered an essential condition for achieving a successful treatment team. High cohesion groups more readily reach their goals, with group members also feeling more secure about their functions and contributions. In clinical practice, nurses use group teaching and group therapy to help patient and family members gain knowledge and skills related to illness treatment and recuperation. Effective group leadership helps minimize non-productive time and manpower and enhance interpersonal interaction. A further advantage of group cohesion is that the more effective administration of nursing programs that results can raise the profession level of staffs and reduce turnover. Walker and Avant (1995) employ concept analysis to use defining attributes in order to apply the same definition and communication to the same profession. The purpose of this paper was to apply this methodology to an analysis of group cohesion. Steps used include a review of the literature on conceptual definitions of group cohesion, a determination of defining attributes, model construction, identification of borderline, contrary, and related cases, and identification of antecedents and consequences and empirical tools. It is hoped that this analysis can help nursing staff to gain a better understanding of the concept of group cohesion and to apply such to clinical practice and nursing administration.

    Full Text Available Abstract Background The allocation of outcome of suicide attempters is extremely important in emergency situations. Following categorization of suicidal attempters who visited the emergency room by outcome, we aimed to identify the characteristics and potential needs of each group. Methods The outcomes of 1348 individuals who attempted suicide and visited the critical care center or the psychiatry emergency department of the hospital were categorized into 3 groups, "hospitalization in the critical care center (HICCC", "hospitalization in the psychiatry ward (HIPW", or "non-hospitalization (NH", and the physical, mental, and social characteristics of these groups were compared. In addition, multiple logistic analysis was used to extract factors related to outcome. Results The male-to-female ratio was 1:2. The hospitalized groups, particularly the HICCC group, were found to have biopsychosocially serious findings with regard to disturbance of consciousness (JCS, general health performance (GAS, psychiatric symptoms (BPRS, and life events (LCU, while most subjects in the NH group were women who tended to repeat suicide-related behaviors induced by relatively light stress. The HIPW group had the highest number of cases, and their symptoms were psychologically serious but physically mild. On multiple logistic analysis, outcome was found to be closely correlated with physical severity, risk factor of suicide, assessment of emergent medical intervention, and overall care. Conclusion There are different potential needs for each group. The HICCC group needs psychiatrists on a full-time basis and also social workers and clinical psychotherapists to immediately initiate comprehensive care by a medical team composed of multiple professionals. The HIPW group needs psychological education to prevent repetition of suicide attempts, and high-quality physical treatment and management skill of the staff in the psychiatric ward. The NH group subjects need a

    A rehabilitation center is another form of health care organization that specializes in providing care for particular conditions of patients. Patients admitted in rehab centers range from being accident victims to those suffering with a specific illness. These organizations are becoming extremely valuable in providing patient care services. However, they have not marketed themselves as aggressively as other health care organizations. This article provides an insight regarding rehab centers and examines marketing issues using a SWOT (strengths, weaknesses, opportunities, and threats) analysis. It further provides some future prospects and challenges for marketers of these organizations.

    Reichman, O. J.

    2001-12-01

    The National Center for Ecological Analysis and Synthesis was created in May 1995 with funding from NSF, the State of California, and UCSB. The Center is based on the premise that a significant amount is known about the environment, but that it is scattered in many places and formats. The purpose of the Center is to obtain and utilize existing information to address important ecological questions. The Center was recently funded by NSF for an additional 6 years. The Center supports several types of research activities. A primary mode of research is through Working Groups, projects made up of approximately a dozen scientists who come to NCEAS to concentrate on specific issues that require in-depth analysis of data and synthesis of ideas. In addition, up to six sabbatical visitors (Center Fellows) and 18 Postdoctoral Associates are in residence at the Center. Since the Center began, over 2,400 scientists (including hundreds of students) from the US and 40 other countries have participated in research activities. These scientists have produced more than 380 scientific articles published in 65 journals and 8 books. The topics addressed by research projects at the Center range from the value of the planet's ecosystem services to the ecological impacts of global climate change. The Center is actively involved in developing a Knowledge Network for Biocomplexity (knb.ecoinformatics.org) involving information management tools for access to ecological data, which are highly dispersed and heterogeneous. The research and implementation involves developing a desktop data management system for individuals researchers and research groups. Embedded in the system would be capabilities for developing metadata (data about data), making both the metadata and raw data available to the broad community interested in such information, and data query tools (knb.ecoinformatics.org).

These sites play an expanded role within the system. The philosophy and function of these centers is discussed and details of their composition and operation are outlined. The plan for future additional centers is also addressed.

  7. Change mechanisms of schema-centered group psychotherapy with personality disorder patients.

    Directory of Open Access Journals (Sweden)

    Wolfgang Tschacher

    Full Text Available BACKGROUND: This study addressed the temporal properties of personality disorders and their treatment by schema-centered group psychotherapy. It investigated the change mechanisms of psychotherapy using a novel method by which psychotherapy can be modeled explicitly in the temporal domain. METHODOLOGY AND FINDINGS: 69 patients were assigned to a specific schema-centered behavioral group psychotherapy, 26 to social skills training as a control condition. The largest diagnostic subgroups were narcissistic and borderline personality disorder. Both treatments offered 30 group sessions of 100 min duration each, at a frequency of two sessions per week. Therapy process was described by components resulting from principal component analysis of patients' session-reports that were obtained after each session. These patient-assessed components were Clarification, Bond, Rejection, and Emotional Activation. The statistical approach focused on time-lagged associations of components using time-series panel analysis. This method provided a detailed quantitative representation of therapy process. It was found that Clarification played a core role in schema-centered psychotherapy, reducing rejection and regulating the emotion of patients. This was also a change mechanism linked to therapy outcome. CONCLUSIONS/SIGNIFICANCE: The introduced process-oriented methodology allowed to highlight the mechanisms by which psychotherapeutic treatment became effective. Additionally, process models depicted the actual patterns that differentiated specific diagnostic subgroups. Time-series analysis explores Granger causality, a non-experimental approximation of causality based on temporal sequences. This methodology, resting upon naturalistic data, can explicate mechanisms of action in psychotherapy research and illustrate the temporal patterns underlying personality disorders.

    Gantt, Susan P; Agazarian, Yvonne M

    2010-10-01

    This article introduces the systems-centered concept of the "group mind" by linking systems-centered thinking and interpersonal neurobiology, building on Siegel's definition of mind as the process of regulating the flow of energy and information. Functional subgrouping, the systems-centered group method for resolving conflicts, discriminates and integrates the flow of energy and information within and between group members, subgroups, and the group-as-a-whole, thus potentiating survival, development, and transformation. This article uses the interpersonal neurobiological framework to discuss functional subgrouping as a tool for developing the group mind: considering how functional subgrouping facilitates emotional regulation, creates a secure relational context, and potentiates neural integration.

    2015-10-30

    Group violence among Latin American immigrant youth has led to ongoing debates in political, legal, and media circles, yet none of those many perspectives has arrived at a solid, empirically supported definition for the phenomenon. This study aims to explore the relationship between the immigrant experience and violent group behavior in youths from Latin America serving prison sentences in Justice Enforcement Centers in the Community of Madrid. Semi-structured interviews were conducted with 19 juveniles, and content analysis was applied to the resulting transcripts, employing Grounded Theory to create an axial codification of intra- and inter-categorical contents, and Delphi panels for quality control. The research team delved into 62 topics, addressing participants' perceptions of the immigrant experience and its effects on five socialization settings (neighborhood, school, family, peer group, and significant other), and each one's relationship to violent behavior. The results led us to believe the young people's immigration experiences had been systematically examined. Their personal and social development was influenced by negative socioeconomic conditions, ineffective parental supervision, maladjustment and conflict at school, and experiences of marginalization and xenophobia. All those conditions favored affiliation with violent groups that provided them instrumental (economic and material), expressive, or affective support.

    2016-06-01

    This analysis compared the numbers of patients treated at Italian pediatric oncology group (Associazione Italiana Ematologia Oncologia Pediatrica [AIEOP]) centers with the numbers of cases predicted according to the population-based registry. It considered 32,431 patients registered in the AIEOP database (1989-2012). The ratio of observed (O) to expected (E) cases was 0.79 for children (0-14 years old) and 0.15 for adolescents (15-19 years old). The proportion of adolescents increased significantly over the years, however, from 0.05 in the earliest period to 0.10, 0.18, and then 0.28 in the latest period of observation, suggesting a greater efficacy of local/national programs dedicated to adolescents.

    Science.gov (United States)

    Nishida, Yusuke

    2016-08-01

    We develop a field-theoretic approach to massless Dirac fermions in a supercritical Coulomb potential. By introducing an Aharonov-Bohm solenoid at the potential center, the critical Coulomb charge can be made arbitrarily small for one partial-wave sector, where a perturbative renormalization group analysis becomes possible. We show that a scattering amplitude for reflection of particle at the potential center exhibits the renormalization group limit cycle, i.e., log-periodic revolutions as a function of the scattering energy, revealing the emergence of discrete scale invariance. This outcome is further incorporated in computing the induced charge and current densities, which turn out to have power-law tails with coefficients log-periodic with respect to the distance from the potential center. Our findings are consistent with the previous prediction obtained by directly solving the Dirac equation and can in principle be realized by graphene experiments with charged impurities.

This outcome is further incorporated in computing the induced charge and current densities, which turn out to have power law tails with coefficients log-periodic with respect to the distance from the potential center. Our findings are consistent with the previous prediction obtained by directly solving the Dirac equation and can in principle be realized by graphene experiments with charged impurities.

    Providing comprehensive care for chronic pelvic pain is impeded by time and resource constraints of the standard health care visit. To provide patient education, psychosocial support, and health care assessment, we developed group visits for women with chronic pelvic pain using an evidence-based, holistic nursing approach. In this article, we describe the structure of group visits, the process of conducting Centering group visits focused on empowerment, and the content of a holistic curriculum for women with chronic pelvic pain.

  1. Group adaptation, formal darwinism and contextual analysis.

    Okasha, S; Paternotte, C

    2012-06-01

    We consider the question: under what circumstances can the concept of adaptation be applied to groups, rather than individuals? Gardner and Grafen (2009, J. Evol. Biol.22: 659-671) develop a novel approach to this question, building on Grafen's 'formal Darwinism' project, which defines adaptation in terms of links between evolutionary dynamics and optimization. They conclude that only clonal groups, and to a lesser extent groups in which reproductive competition is repressed, can be considered as adaptive units. We re-examine the conditions under which the selection-optimization links hold at the group level. We focus on an important distinction between two ways of understanding the links, which have different implications regarding group adaptationism. We show how the formal Darwinism approach can be reconciled with G.C. Williams' famous analysis of group adaptation, and we consider the relationships between group adaptation, the Price equation approach to multi-level selection, and the alternative approach based on contextual analysis.

    Full Text Available The purpose of this study is to evaluate and compare efficiency of research groups in the Center of Social and Cultural Research. There are several tools for efficiency evaluation. The method used in this study was Data Envelopment Analysis (DEA in which rate of output is evaluated by input and effective and non-effective units are determined. The first step in DEA is to prepare a list of inputs and outputs. The inputs in this study were personnel and administrative costs, the ratio of group staff to the total staff of the center and person-hours of labor. The outputs of this study contained the number of finished research projects, proportion of allocated budget to the total budget issued and the Percent of the projects’ progress. The survey was carried out in 20 research groups, using DEA method. The analysis indicated that 5 groups were efficient and 3 groups were on border line. To improve non-efficient groups and converting them to efficient ones, we suggest some adjustments in inputs and outputs.

    The primary payload for Space Shuttle Mission STS-42, launched January 22, 1992, was the International Microgravity Laboratory-1 (IML-1), a pressurized manned Spacelab module. The goal of IML-1 was to explore in depth the complex effects of weightlessness of living organisms and materials processing. Around-the-clock research was performed on the human nervous system's adaptation to low gravity and effects of microgravity on other life forms such as shrimp eggs, lentil seedlings, fruit fly eggs, and bacteria. Materials processing experiments were also conducted, including crystal growth from a variety of substances such as enzymes, mercury iodide, and a virus. The Huntsville Operations Support Center (HOSC) Spacelab Payload Operations Control Center (SL POCC) at the Marshall Space Flight Center (MSFC) was the air/ground communication channel used between the astronauts and ground control teams during the Spacelab missions. Featured is the Critical Point Facility (CPE) group in the SL POCC during STS-42, IML-1 mission.

    Patient education in mental health care is a conventional intervention to increase patients' knowledge about their illness and treatment. A provider-centered focus in patient education may put patients in a passive role, which can counteract their processes of recovery. There is an increasing emphasis on recovery-oriented practice, an approach that is aligned with the service user perspective, but little is known about health care staff's perspectives on person-centered mental health care. A qualitative approach was used to describe staff's experiences of being group leaders in a person-centered health education intervention in municipal services for persons with a persistent mental illness. The analysis of staff experiences revealed three core categories: (1) implications of the division of responsibility among local authorities, (2) awareness of facilitating factors of growth, and (3) the meaning of dialogue. These formed the theme Preconditions for Person-Centered Care. Further research is required to explore larger economic, political, and social structures as backdrops to person-centered mental health care, from the perspective of service users, families, health professionals, and the community at large.

  9. Analysis of the Entanglement with Centers

    CERN Document Server

    Huang, Xing

    2016-01-01

    Entanglement in gauge theories is difficult to define because of the issue of a tensor product decomposition of a Hilbert space. We choose centers to define quantities that quantify the entanglement, and also use quantization algebras and constraints to analyze the existence of the ambiguities in a system of first-order formulation. In interacting theories, lattice simulations is required to obtain quantitative behaviors of entanglement. Thus, we propose a method to study entanglement with centers on finite spacing lattice without breaking gauge symmetry. We also understand the relation between the extended lattice model and boundary condition, and discuss magnetic choices in the extended lattice model. Then we compute the entanglement entropy in $p$-form free theory in $2p+2$ dimensional Euclidean flat background with a $S^{2p}$ entangling surface, our results support that the ambiguities in non-gauge theories only affect the regulator dependent terms. The universal terms of the entanglement entropy in $p$-f...

    Bloomfield, Joanna; Rising, Sharon Schindler

    2013-01-01

    CenteringParenting is a group model that brings a cohort of 6 to 7 mothers and infants together for care during the first year of life. During 9 group sessions the clinician provides well-baby care and also attends to the health, development, and safety issues of the mother. Ideally, CenteringParenting provides continuity of care for a cohort of women who have received care in CenteringPregnancy, group prenatal care that is 10 sessions throughout the entire pregnancy and that leads to community building, better health outcomes, and increased satisfaction with prenatal care. The postpartum year affects the entire family, but especially the mother, who is redefining herself and her own personal goals. Issues of weight/body image, breastfeeding, depression, contraception, and relationship issues all may surface. In traditional care, health resources for support and intervention are frequently lacking or unavailable. Women's health clinicians also note the loss of contact with women they have followed during the prenatal period, often not seeing a woman again until she returns for another pregnancy. CenteringParenting recognizes that the health of the mother is tied to the health of the infant and that assessment and interventions are more appropriate and efficient when done in a dyad context. Facilitative leadership, rather than didactic education, encourages women to fully engage in their care, to raise issues of importance to them, and to discuss concerns within an atmosphere that allows for the surfacing of culturally appropriate values and beliefs. Implementing the model calls for system changes that are often significant. It also requires the building of a substantial team relationship among care providers. This overview describes the CenteringParenting mother-infant dyad care model with special focus on the mother and reviews the perspectives and experiences of staff from several practice sites.

    This book is the first one that brings together recent results on the harmonic analysis of exponential solvable Lie groups. There still are many interesting open problems, and the book contributes to the future progress of this research field. As well, various related topics are presented to motivate young researchers. The orbit method invented by Kirillov is applied to study basic problems in the analysis on exponential solvable Lie groups. This method tells us that the unitary dual of these groups is realized as the space of their coadjoint orbits. This fact is established using the Mackey theory for induced representations, and that mechanism is explained first. One of the fundamental problems in the representation theory is the irreducible decomposition of induced or restricted representations. Therefore, these decompositions are studied in detail before proceeding to various related problems: the multiplicity formula, Plancherel formulas, intertwining operators, Frobenius reciprocity, and associated alge...

    This report will give an explanation of the internal reorganization that has been done because of the necessity to optimize operation in the cooling and ventilation group. The basic structure for the group was defined at the end of 1998. We understood then that change was needed to accommodate the increased workload due to the LHC project. In addition, we face a relatively large turnover of personnel (retirements and some recruitment) with related integration issues to consider. We would also like to implement new approaches in the management of both operations and maintenance. After some running-in problems during the first half of 1999, we realized that much more could be gained with the analysis and the definition and documenting of each single function and generic activity within the group. The authors will explain how this analysis was carried out and give some feedback of the outcome, so far.

    The vast majority of Americans do not engage in adequate regular physical activity despite its well-known health benefits. Even when individuals attempt to become more active by joining a fitness center, estimates suggest that nearly half terminate their membership within the first 6 months. A better understanding of who is at risk for early membership termination upon joining may help researchers develop targeted interventions to improve the likelihood that individuals will successfully maintain memberships and physical activity. This study's purpose was to identify, based on a wellness assessment (WA) used in fitness centers, individuals at risk for fitness membership termination prior to 1-year. Center members (N = 441; Mage = 41.9, SD = 13.1; 74.4% female) completed a comprehensive WA of stress, life satisfaction, physical fitness, metabolic health, and sleep quality at the beginning of their memberships and were followed for one year. Latent class analyses utilized the WA to identify four groups: (a) healthy, (b) unhealthy, (c) poor psychological wellness, and (d) poor physical wellness. Participants in the poor psychological wellness group (OR = 2.24, p = 0.007) and the unhealthy group (OR = 2.40, p = 0.037) were significantly more likely to terminate their memberships at 1-year as compared to the healthy group. Participants with poor physical wellness visited the fitness center less frequently than healthy participants (p psychological wellness is a risk factor for terminating memberships, whereas poor physical wellness is not. Future studies should replicate these latent classes and develop targeted interventions to address psychological wellness as a method to improve fitness membership retention.

    Objective The aim of this study was to investigate the three-dimensional (3D) position of the center of resistance of 4 mandibular anterior teeth, 6 mandibular anterior teeth, and the complete mandibular dentition by using 3D finite-element analysis. Methods Finite-element models included the complete mandibular dentition, periodontal ligament, and alveolar bone. The crowns of teeth in each group were fixed with buccal and lingual arch wires and lingual splint wires to minimize individual tooth movement and to evenly disperse the forces onto the teeth. Each group of teeth was subdivided into 0.5-mm intervals horizontally and vertically, and a force of 200 g was applied on each group. The center of resistance was defined as the point where the applied force induced parallel movement. Results The center of resistance of the 4 mandibular anterior teeth group was 13.0 mm apical and 6.0 mm posterior, that of the 6 mandibular anterior teeth group was 13.5 mm apical and 8.5 mm posterior, and that of the complete mandibular dentition group was 13.5 mm apical and 25.0 mm posterior to the incisal edge of the mandibular central incisors. Conclusions Finite-element analysis was useful in determining the 3D position of the center of resistance of the 4 mandibular anterior teeth group, 6 mandibular anterior teeth group, and complete mandibular dentition group.

    2013-09-01

    There exists a paucity of ethics resources tailored to rehabilitation. To help fill this ethics resource gap, the authors developed an ethics analysis model specifically for use in rehabilitation care. The Patient-Centered Care Ethics Analysis Model for Rehabilitation is a process model to guide careful moral reasoning for particularly complex or challenging matters in rehabilitation. The Patient-Centered Care Ethics Analysis Model for Rehabilitation was developed over several iterations, with feedback at different stages from rehabilitation professionals and bioethics experts. Development of the model was explicitly informed by the theoretical grounding of patient-centered care and the context of rehabilitation, including the International Classification of Functioning, Disability and Health. Being patient centered, the model encourages (1) shared control of consultations, decisions about interventions, and management of the health problems with the patient and (2) understanding the patient as a whole person who has individual preferences situated within social contexts. Although the major process headings of the Patient-Centered Care Ethics Analysis Model for Rehabilitation resemble typical ethical decision-making and problem-solving models, the probes under those headings direct attention to considerations relevant to rehabilitation care. The Patient-Centered Care Ethics Analysis Model for Rehabilitation is a suitable tool for rehabilitation professionals to use (in real time, for retrospective review, and for training purposes) to help arrive at ethical outcomes.

    Internet Cancer Support Groups (ICSGs) are an emerging form of support group on Internet specifically for cancer patients. Previous studies have indicated the effectiveness of ICSGs as a research setting or a data-collection method. Yet recent studies have also indicated that ICSGs tend to serve highly educated, high-income White males who tend to be at an early stage of cancer. In this article, a total of 317 general ICSGs and 229 ethnic-specific ICSGs searched through Google.com, Yahoo.com, Msn.com, AOL.com, and ACOR.org are analyzed from a feminist perspective. The written records of group discussions and written memos by the research staff members were also analyzed using content analysis. The idea categories that emerged about these groups include (a) authenticity issues; (b) ethnicity and gender issues; (c) intersubjectivity issues; and (d) potential ethical issues. The findings suggest that (a) researchers adopt multiple recruitment strategies through various Internet sites and/or real settings; (b) researchers raise their own awareness of the potential influences of the health-related resources provided by ICSGs and regularly update their knowledge related to the federal and state standards and/or policies related to ICSGs; and (c) researchers consider adopting a quota-sampling method.

  6. Conformational differences between the methoxy groups of QA and QB site ubisemiquinones in bacterial reaction centers: a key role for methoxy group orientation in modulating ubiquinone redox potential.

    Ubiquinone is an almost universal, membrane-associated redox mediator. Its ability to accept either one or two electrons allows it to function in critical roles in biological electron transport. The redox properties of ubiquinone in vivo are determined by its environment in the binding sites of proteins and by the dihedral angle of each methoxy group relative to the ring plane. This is an attribute unique to ubiquinone among natural quinones and could account for its widespread function with many different redox complexes. In this work, we use the photosynthetic reaction center as a model system for understanding the role of methoxy conformations in determining the redox potential of the ubiquinone/semiquinone couple. Despite the abundance of X-ray crystal structures for the reaction center, quinone site resolution has thus far been too low to provide a reliable measure of the methoxy dihedral angles of the primary and secondary quinones, QA and QB. We performed 2D ESEEM (HYSCORE) on isolated reaction centers with ubiquinones (13)C-labeled at the headgroup methyl and methoxy substituents, and have measured the (13)C isotropic and anisotropic components of the hyperfine tensors. Hyperfine couplings were compared to those derived by DFT calculations as a function of methoxy torsional angle allowing estimation of the methoxy dihedral angles for the semiquinones in the QA and QB sites. Based on this analysis, the orientation of the 2-methoxy groups are distinct in the two sites, with QB more out of plane by 20-25°. This corresponds to an ≈50 meV larger electron affinity for the QB quinone, indicating a substantial contribution to the experimental difference in redox potentials (60-75 mV) of the two quinones. The methods developed here can be readily extended to ubiquinone-binding sites in other protein complexes.

    Ubiquinone is an almost universal, membrane-associated redox mediator. Its ability to accept either one or two electrons allows it to function in critical roles in biological electron transport. The redox properties of ubiquinone in vivo are determined by its environment in the binding sites of proteins and by the dihedral angle of each methoxy group relative to the ring plane. This is an attribute unique to ubiquinone among natural quinones and could account for its widespread function with many different redox complexes. In this work, we use the photosynthetic reaction center as a model system for understanding the role of methoxy conformations in determining the redox potential of the ubiquinone/semiquinone couple. Despite the abundance of X-ray crystal structures for the reaction center, quinone site resolution has thus far been too low to provide a reliable measure of the methoxy dihedral angles of the primary and secondary quinones, QA and QB. We performed 2D ESEEM (HYSCORE) on isolated reaction centers with ubiquinones 13C-labeled at the headgroup methyl and methoxy substituents, and have measured the 13C isotropic and anisotropic components of the hyperfine tensors. Hyperfine couplings were compared to those derived by DFT calculations as a function of methoxy torsional angle allowing estimation of the methoxy dihedral angles for the semiquinones in the QA and QB sites. Based on this analysis, the orientation of the 2-methoxy groups are distinct in the two sites, with QB more out of plane by 20-30°. This corresponds to an ≈50 meV larger electron affinity for the QB quinone, indicating a substantial contribution to the experimental difference in redox potentials (60-75 mV) of the two quinones. The methods developed here can be readily extended to ubiquinone-binding sites in other protein complexes. PMID:23745576

    We present a weak lensing analysis of a sample of SDSS Compact Groups (CGs). Using the measured radial density contrast profile, we derive the average masses under the assumption of spherical symmetry, obtaining a velocity dispersion for the Singular Isothermal Spherical model, σV = 270 ± 40 km s-1, and for the NFW model, R_{200}=0.53± 0.10 h_{70}^{-1}Mpc. We test three different definitions of CGs centres to identify which best traces the true dark matter halo centre, concluding that a luminosity weighted centre is the most suitable choice. We also study the lensing signal dependence on CGs physical radius, group surface brightness, and morphological mixing. We find that groups with more concentrated galaxy members show steeper mass profiles and larger velocity dispersions. We argue that both, a possible lower fraction of interloper and a true steeper profile, could be playing a role in this effect. Straightforward velocity dispersion estimates from member spectroscopy yields σV ≈ 230 km s-1 in agreement with our lensing results.

    Large-scale audiovisual data that measure group learning are time consuming to collect and analyze. As an initial step towards scaling qualitative classroom observation, we qualitatively coded classroom video using an established coding scheme with and without its audio cues. We find that interrater reliability is as high when using visual data only—without audio—as when using both visual and audio data to code. Also, interrater reliability is high when comparing use of visual and audio data to visual-only data. We see a small bias to code interactions as group discussion when visual and audio data are used compared with video-only data. This work establishes that meaningful educational observation can be made through visual information alone. Further, it suggests that after initial work to create a coding scheme and validate it in each environment, computer-automated visual coding could drastically increase the breadth of qualitative studies and allow for meaningful educational analysis on a far greater scale.

    The health sector's increasing complexity poses major challenges for administrators. There is considerable consensus on workforce quality as a key determinant of success for any health reform. This study aimed to explore the changes introduced by an action-training intervention in the organizational culture of the 73 executive directors of Health Center Groups (ACES) in Portugal during the primary health care reform. The study covers two periods, before and after the one-year ACES training, during which the data were collected and analyzed. The Competing Values Framework allowed observing that after the ACES action-training intervention, the perceptions of the executive directors regarding their organizational culture were more aligned with the practices and values defended by the primary health care reform. The study highlights the need to continue monitoring results over different time periods to elaborate further conclusions.

    Spiral analysis is a computerized method that measures human motor performance from handwritten Archimedean spirals. It quantifies normal motor activity, and detects early disease as well as dysfunction in patients with movement disorders. The clinical utility of spiral analysis is based on kinematic and dynamic indices derived from the original spiral trace, which must be detected and transformed into mathematical expressions with great precision. Accurately determining the center of the spiral and reducing spurious low frequency noise caused by center selection error is important to the analysis. Handwritten spirals do not all start at the same point, even when marked on paper, and drawing artifacts are not easily filtered without distortion of the spiral data and corruption of the performance indices. In this report, we describe a method for detecting the optimal spiral center and reducing the unwanted drawing artifacts. To demonstrate overall improvement to spiral analysis, we study the impact of the optimal spiral center detection in different frequency domains separately and find that it notably improves the clinical spiral measurement accuracy in low frequency domains.

    The Chinese Medical Doctor's Association asked us to develop a train-the-trainers program in doctor-patient communication and in teaching skills for a select group of Chinese health care professionals, who would then serve as trainers for practicing physicians throughout China. The request came in the context of increasing doctor-patient friction related, in part, to the dissolution of the socialist health care safety net in China. In this article we recount the implementation of our 5-day training program in Beijing. We explore cross-cultural issues that arose in presenting the program's two principal training domains: small group teaching and patient-centered doctor-patient communication. We also explore the linguistic challenges we encountered as non-Chinese speaking teachers. Finally, we reflect on the lessons learned from this project that may be of value to others called upon to export Western doctor-patient communications training to other cultures. In this age of increasing globalization, cross-cultural sharing of medical education represents a growing trend.

    2008-01-01

    Case illustrations from group dynamic cognitive behavioral group therapy are presented to demonstrate three applications of functional analysis and the resulting cognitive behavioral interventions. The principles of group dynamic cognitive behavioral group therapy are explained. A functional analysis is applied first to the problem behavior of an individual group member. A clinical case illustrates how the group members help to change this individual group member's behavior from a learning theory perspective. Next, the circular interactional problem behavior between two group members is reduced to the individual functional analysis of each of the two member's problem behaviors. It is then illustrated how the two group member's problem behaviors, as well as feedback from others, contribute toward helping to change each others behavior. The paper concludes that functional analysis and ensuing behavioral interventions can be also applied to group as a whole behavior.

    2015-01-01

    According to the subjectivity and fuzziness of analysis on failure mode severity about spindle system of machining center, an analysis model of the failure mode severity of such a system is proposed based on the new fault severity index system, improved analytic hierarchy process ( IAHP ) and entropy⁃based fuzzy comprehensive evaluation. IAHP and entropy methods are adopted to determine the comprehensive failure severity index weight. The evaluation result is obtained after the factor set, comment set, weight set, and other parameters are determined, and then the level of risk degree and numerical value order of every spindle system failure mode is given. By taking an example, we verify that the proposed method can quantify the qualitative problem comprehensively, obtain more accurate analysis results, and provide the theoretical reference for mechanization and sequencing of failure mode effect analysis in reliability analysis. The calculation results can also serve as the basis of failure mode, effects, and criticality analysis in the subsequent step.

    The refractory research group at the Albany Research Center (ARC) has a long history of conducting materials research within the U.S. Bureau of Mines, and more recently, within the U.S. Dept. of Energy. When under the U.S. Bureau of Mines, research was driven by national needs to develop substitute materials and to conserve raw materials. This mission was accomplished by improving refractory material properties and/or by recycling refractories using critical and strategic materials. Currently, as a U.S. Dept of Energy Fossil Energy field site, research is driven primarily by the need to assist DOE in meeting its vision to develop economically and environmentally viable technologies for the production of electricity from fossil fuels. Research at ARC impacts this vision by: • Providing information on the performance characteristics of materials being specified for the current generation of power systems; • Developing cost-effective, high performance materials for inclusion in the next generation of fossil power systems; and • Solving environmental emission and waste problems related to fossil energy systems. A brief history of past refractory research within the U.S. Bureau of Mines, the current refractory research at ARC, and the equipment and capabilities used to conduct refractory research at ARC will be discussed.

    2016-01-01

    A new computational scheme to analyze electron transfer (ET) pathways in large biomolecules is presented with applications to ETs in bacterial photosynthetic reaction center. It consists of a linear combination of fragment molecular orbitals and an electron tunneling current analysis, which enables an efficient first-principles analysis of ET pathways in large biomolecules. The scheme has been applied to the ET from menaquinone to ubiquinone via nonheme iron complex in bacterial photosynthetic reaction center. It has revealed that not only the central Fe$^{2+}$ ion but also particular histidine ligands are involved in the ET pathways in such a way to mitigate perturbations that can be caused by metal ion substitution and depletion, which elucidates the experimentally observed insensitivity of the ET rate to these perturbations.

    Frew, J E

    1990-04-01

    In Gestalt therapy, transference is viewed as a contact boundary disturbance which impairs the patient's ability to accurately perceive the present therapy situation. The boundary disturbances in Gestalt therapy most closely related to the analytic notion of transference are projection, introjection, and confluence. In Gestalt group psychotherapy, group members interfere with the process of need identification and satisfaction by distorting their contact with each other through projecting, introjecting, and being confluent. The Gestalt group therapist uses interventions directed to individuals and to the group to increase participants' awareness of these boundary disturbances and of the present contact opportunities available to them when these disturbances are resolved. In formulating interventions, the leader is mindful of the function of boundary disturbances to the group-as-a-whole as well as to individuals.

    This paper presents a detailed convective forecast accuracy analysis at center and sector levels. The study is aimed to provide more meaningful forecast verification measures to aviation community, as well as to obtain useful information leading to the improvements in the weather translation capacity models. In general, the vast majority of forecast verification efforts over past decades have been on the calculation of traditional standard verification measure scores over forecast and observation data analyses onto grids. These verification measures based on the binary classification have been applied in quality assurance of weather forecast products at the national level for many years. Our research focuses on the forecast at the center and sector levels. We calculate the standard forecast verification measure scores for en-route air traffic centers and sectors first, followed by conducting the forecast validation analysis and related verification measures for weather intensities and locations at centers and sectors levels. An approach to improve the prediction of sector weather coverage by multiple sector forecasts is then developed. The weather severe intensity assessment was carried out by using the correlations between forecast and actual weather observation airspace coverage. The weather forecast accuracy on horizontal location was assessed by examining the forecast errors. The improvement in prediction of weather coverage was determined by the correlation between actual sector weather coverage and prediction. observed and forecasted Convective Weather Avoidance Model (CWAM) data collected from June to September in 2007. CWAM zero-minute forecast data with aircraft avoidance probability of 60% and 80% are used as the actual weather observation.

    Intersubjectivity can be defined as the union or contact of the subjectivities (Gordon, 1991). In therapy, it refers to the interaction between therapist and patient, and the processes that affect and are affected by that interaction. The essence of these interactions in the setting of group therapy, the obstacles that may arise because of them, and ways in which the therapist may identify and facilitate intersubjectivity in order to promote discourse that will enrich the sessions are discussed. I briefly touch upon earlier theories of psychoanalysis, demonstrating how changes in approaches influenced perceptions of what occurs in therapy. The unique place of intersubjectivity within the group analytic setting is emphasized using several vignettes from sessions I have led as a group analyst candidate to better illustrate how intersubjectivity can be observed in vivo.

    2009-07-01

    Even though frequency analysis of body sway is widely applied in clinical studies, the lack of standardized procedures concerning power spectrum estimation may provide unreliable descriptors. Stabilometric tests were applied to 35 subjects (20-51 years, 54-95 kg, 1.6-1.9 m) and the power spectral density function was estimated for the anterior-posterior center of pressure time series. The median frequency was compared between power spectra estimated according to signal partitioning, sampling rate, test duration, and detrending methods. The median frequency reliability for different test durations was assessed using the intraclass correlation coefficient. When increasing number of segments, shortening test duration or applying linear detrending, the median frequency values increased significantly up to 137%. Even the shortest test duration provided reliable estimates as observed with the intraclass coefficient (0.74-0.89 confidence interval for a single 20-s test). Clinical assessment of balance may benefit from a standardized protocol for center of pressure spectral analysis that provides an adequate relationship between resolution and variance. An algorithm to estimate center of pressure power density spectrum is also proposed.

    1999-01-01

    We compute the acceleration on the Local Group using 11206 IRAS galaxies from the recently completed all-sky PSCz redshift survey. Measuring the acceleration vector in redshift space generates systematic uncertainties due to the redshift space distortions in the density field. We therefore assign galaxies to their real space positions by adopting a non-parametric model for the velocity field that solely relies on the linear gravitational instability and linear biasing hypotheses. Remaining systematic contributions to the measured acceleration vector are corrected for by using PSCz mock catalogues from N-body experiments. The resulting acceleration vector points approx. 15 degrees away from the CMB dipole apex, with a remarkable alignment between small and large scale contributions. A considerable fraction of the measured acceleration is generated within 40 h-1 Mpc with a non-negligible contribution from scales between 90 and 140 h-1 Mpc after which the acceleration amplitude seems to have converged. The local...

  2. Development of renormalization group analysis of turbulence

    Science.gov (United States)

    Smith, L. M.

    1990-01-01

    The renormalization group (RG) procedure for nonlinear, dissipative systems is now quite standard, and its applications to the problem of hydrodynamic turbulence are becoming well known. In summary, the RG method isolates self similar behavior and provides a systematic procedure to describe scale invariant dynamics in terms of large scale variables only. The parameterization of the small scales in a self consistent manner has important implications for sub-grid modeling. This paper develops the homogeneous, isotropic turbulence and addresses the meaning and consequence of epsilon-expansion. The theory is then extended to include a weak mean flow and application of the RG method to a sequence of models is shown to converge to the Navier-Stokes equations.

    de Grijs, Richard

    2016-01-01

    Aiming at deriving a statistically well-justified Galactic Center distance, $R_0$, and reducing any occurrence of publication bias, we compiled the most comprehensive and most complete database of Galactic Center distances available to date, containing 273 new or revised $R_0$ estimates published since records began in October 1918 until June 2016. We separate our $R_0$ compilation into direct and indirect distance measurements. The latter include a large body of estimates that rely on centroid determinations for a range of tracer populations as well as measurements based on kinematic observations of objects at the solar circle, combined with a mass and/or rotational model of the Milky Way. Careful assessment of the Galactic Center distances resulting from orbital modeling and statistical parallax measurements in the Galactic nucleus yields our final Galactic Center distance recommendation of $R_0 = 8.3 \\pm 0.2 \\mbox{ (statistical)} \\pm 0.4 \\mbox{ (systematic)}$ kpc.

    AIM: To review the outcomes of liver trauma in patients with hepatic injuries only and in patients with associated injuries outside the liver.METHODS: Data of liver trauma patients presented to our center from January 2003 to October 2013 were reviewed. The patients were divided into two groups. Group 1 consisted of patients who had hepatic injuries only. Group 2 consisted of patients who also had associated injuries outside the liver.RESULTS: Seven(30.4%) patients in group 1 and 10(28.6%) patients in group 2 received non-operative management; the rest underwent operation. Blunt trauma occurred in 82.8%(48/58) of the patients and penetrative trauma in 17.2%(10/58). A higher injury severity score(ISS) was observed in group 2(median 45 vs 25, P < 0.0001). More patients in group 1 were hemodynamically stable(65.2% vs 37.1%, P = 0.036). Other parameters were comparable between groups. Group 1 had better 30-d survival(91.3% vs 71.4%, P = 0.045). On multivariate analysis using the logistic regression model, ISS was found to be associated with mortality(P = 0.004, hazard ratio = 1.035, 95%CI:CONCLUSION: Liver trauma patients with multiple injuries are relatively unstable on presentation. Despite a higher ISS in group 2, non-operative management was possible for selected patients. Associated injuries outside the liver usually account for morbidity and mortality.

  7. Analysis of a Hybrid Wing Body Center Section Test Article

    Wu, Hsi-Yung T.; Shaw, Peter; Przekop, Adam

    2013-01-01

    The hybrid wing body center section test article is an all-composite structure made of crown, floor, keel, bulkhead, and rib panels utilizing the Pultruded Rod Stitched Efficient Unitized Structure (PRSEUS) design concept. The primary goal of this test article is to prove that PRSEUS components are capable of carrying combined loads that are representative of a hybrid wing body pressure cabin design regime. This paper summarizes the analytical approach, analysis results, and failure predictions of the test article. A global finite element model of composite panels, metallic fittings, mechanical fasteners, and the Combined Loads Test System (COLTS) test fixture was used to conduct linear structural strength and stability analyses to validate the specimen under the most critical combination of bending and pressure loading conditions found in the hybrid wing body pressure cabin. Local detail analyses were also performed at locations with high stress concentrations, at Tee-cap noodle interfaces with surrounding laminates, and at fastener locations with high bearing/bypass loads. Failure predictions for different composite and metallic failure modes were made, and nonlinear analyses were also performed to study the structural response of the test article under combined bending and pressure loading. This large-scale specimen test will be conducted at the COLTS facility at the NASA Langley Research Center.

    The new ohmic heating (OH) coil and center stack for the National Spherical Torus Experiment (NSTX) upgrade are required to meet cooling and structural requirements for operation at the enhanced 1 Tesla toroidal field and 2 MA plasma current. The OH coil is designed to be cooled in the time between discharges by water flowing in the center of the coil conductor. We performed resistive heating and thermal hydraulic analyses to optimize coolant channel size to keep the coil temperature below 100 C and meet the required 20 minute cooling time. Coupled electromagnetic, thermal and structural FEA analyses were performed to determine if the OH coil meets the requirements of the structural design criteria. Structural response of the OH coil to its self-field and the field from other coils was analyzed. A model was developed to analyze the thermal and electromagnetic interaction of centerstack components such as the OH coil, TF inner legs and the Bellville washer preload mechanism. Torsional loads from the TF interaction with the OH and poloidal fields are transferred through the TF flag extensions via a torque transfer coupling to the rest of the tokamak structure. A 3D FEA analysis was performed to qualify this design. The results of these analyses, which will be presented in this paper, have led to the design of OH coil and centerstack components that meet the requirements of the NSTX-upgrade structural design criteria.

  9. Multiple Group Analysis in Multilevel Structural Equation Model Across Level 1 Groups.

    Ryu, Ehri

    2015-01-01

    This article introduces and evaluates a procedure for conducting multiple group analysis in multilevel structural equation model across Level 1 groups (MG1-MSEM; Ryu, 2014). When group membership is at Level 1, multiple group analysis raises two issues that cannot be solved by a simple extension of the standard multiple group analysis in single-level structural equation model. First, the Level 2 data are not independent between Level 1 groups. Second, the standard procedure fails to take into account the dependency between members of different Level 1 groups within the same cluster. The MG1-MSEM approach provides solutions to these problems. In MG1-MSEM, the Level 1 mean structure is necessary to represent the differences between Level 1 groups within clusters. The Level 2 model is the same regardless of Level 1 group membership. A simulation study examined the performance of MUML (Muthén's maximum likelihood) estimation in MG1-MSEM. The MG1-MSEM approach is illustrated for both a multilevel path model and a multilevel factor model using empirical data sets.

    Full Text Available AIM: To evaluate the obstetric referrals to the tertiary center in the current year and to compare the data to the referrals 20 years ago. MATERIALS AND METHODS: This is a retrospective analysis under taken in the Department of OB G, for a period of six months in 2012 - 13 at King George Hospital Visakhapatnam. Data from Medical records during the same months in 1992 - 1993 were obtained. Data of 2012 - 2013 is considered as group - B and data of 1992 - 1993 as group - A. Both are analyzed and compared. RESULTS: Referrals of group - B constituted 51.76% of all the emergency admissions, of which 69.30% were antenatal women. 51.68% were referred in the night between 8pm - 8am. 90.84% were referred from government institutions. Maternal deaths were three and perinatal mortality 35.2%. DISCUSSION: Referrals in the last 20 years increased from 31.64% to 51.76%. In group - B 69.30% were antenatal where as in group A, 81.31% of referrals were in labour. Almost all women were referred in the night in group A. Perinatal mortali ty in group - A was higher (42.54%. CONCLUSION: Under NRHM, and through EmOC program the medical officers of PHCs are trained and infra - structure is being up graded. Hence high risk obstetric women are being identified and are referred earlier. 38.49% of th e women are referred only for conduct of c - section from CHCs and area hospitals in the recent times, where facilities for c - section are supposed to be available. Problems in performing C sections in these centers have to be addressed.

    An outcome evaluation was conducted to obtain psychiatric inpatients' perspectives on acute care mental health treatment and services. The applicability of diagnostic categories based on affective, non-affective, and schizoaffective disorder were considered in the predictability of responses to treatment regimens and the related services provided in an inpatient psychiatric unit. A multidimensional approach was used to survey patients, which included the DAI-30, the BMQ, the SERVQUAL, and the CSQ-8. Overall, findings indicate that inpatient satisfaction could be improved with tailoring treatment to suit their respective symptoms. Furthermore, this exploratory study demonstrates some preliminary support for the inclusion of patients with a diagnosis of schizoaffective disorder as a separate group toward improving acute mental health care while hospitalized.

    Schizophrenia is a highly heritable disorder with a polygenic pattern of inheritance and a population prevalence of ~1%. Previous studies have implicated synaptic dysfunction in schizophrenia. We tested the accumulated association of genetic variants in expert-curated synaptic gene groups with schizophrenia in 4673 cases and 4965 healthy controls, using functional gene group analysis. Identifying groups of genes with similar cellular function rather than genes in isolation may have clinical implications for finding additional drug targets. We found that a group of 1026 synaptic genes was significantly associated with the risk of schizophrenia (P=7.6 × 10(-11)) and more strongly associated than 100 randomly drawn, matched control groups of genetic variants (P<0.01). Subsequent analysis of synaptic subgroups suggested that the strongest association signals are derived from three synaptic gene groups: intracellular signal transduction (P=2.0 × 10(-4)), excitability (P=9.0 × 10(-4)) and cell adhesion and trans-synaptic signaling (P=2.4 × 10(-3)). These results are consistent with a role of synaptic dysfunction in schizophrenia and imply that impaired intracellular signal transduction in synapses, synaptic excitability and cell adhesion and trans-synaptic signaling play a role in the pathology of schizophrenia.

  13. Assessing Group Interaction with Social Language Network Analysis

    Science.gov (United States)

    Scholand, Andrew J.; Tausczik, Yla R.; Pennebaker, James W.

    In this paper we discuss a new methodology, social language network analysis (SLNA), that combines tools from social language processing and network analysis to assess socially situated working relationships within a group. Specifically, SLNA aims to identify and characterize the nature of working relationships by processing artifacts generated with computer-mediated communication systems, such as instant message texts or emails. Because social language processing is able to identify psychological, social, and emotional processes that individuals are not able to fully mask, social language network analysis can clarify and highlight complex interdependencies between group members, even when these relationships are latent or unrecognized.

    Providing students with assignments that focus on critical thinking is an important part of their scientific and intellectual development. However, as class sizes increase, so does the grading burden, prohibiting many faculty from incorporating critical thinking assignments in the classroom. In an effort to continue to provide our students with meaningful critical thinking exercises, we implemented a novel group-centered, problem-based testing scheme. We wanted to assess how performing critical thinking problem sets as group work compares to performing the sets as individual work, in terms of student attitudes and learning outcomes. During two semesters of our recombinant DNA course, students had the same lecture material and similar assessments. In the Fall semester, student learning was assessed by two collaborative take-home exams, followed immediately by individual, closed-book in-class exams on the same content, as well as a final cumulative exam. Student teams on the take-home exams were instructor-assigned, and each team turned in one collaborative exam. In the Spring semester, the control group of students were required to turn in their own individual take-home exams, followed by the in-class exams and final cumulative exam. For the majority of students, learning outcomes were met, regardless of whether they worked in teams. In addition, collaborative learning was favorably received by students and grading was reduced for instructors. These data suggest that group-centered, problem-based learning is a useful model for achievement of student learning outcomes in courses where it would be infeasible to provide feedback on individual critical thinking assignments due to grading volume.

    2016-12-01

    Full Text Available In this research, it is aimed to determine the determinants of service quality perceived by fitness center members. Scanning model from quantitative research methods was used in the research. The study group consisted of 301 women and 390 men in total 691 members who participated the research voluntarily and were selected through an easily accessible sample. The "Sport-Fitness Centers Perceived Service Quality Scale (SFC-PSQS" developed by Uçan (2007 was used in the study. In the analysis of the data, independent t-test, correlation analysis and logistic regression tests were applied. According to obtained findings, significant and moderate relationships were determined between service quality sub-dimensions in positive direction whereas Independent T test results showed that service quality perceptions of participants who evaluated the program as expensive were found to be significantly lower in all sub-dimensions. Considering the logistic regression results, it was determined that variable of "physical environment quality" from perceived service quality sub-dimensions had an effect on the level of program fees of the members. It seems that 1 unit increase in physical environment quality variable caused 6.1% decrease in "program fee prediction" related to odds value. It can be stated that 11% of the total variance of program fee levels predicts perceived service quality. As a result, it is considered that only one factor cannot be effective in ensuring the continuity of sport-fitness center customers and the sustainability of the business. This is because factors such as customer expectations, equipment, experience of fitness center, customer loyalty, physical appearance that may affect individual consumer satisfaction are important factors.

    The main enzymatic reaction of the large ribosomal subunit is peptide bond formation. Ribosome crystallography showed that A2451 of 23S rRNA makes the closest approach to the attacking amino group of aminoacyl-tRNA. Mutations of A2451 had relatively small effects on transpeptidation and failed to unequivocally identify the crucial functional group(s). Here, we employed an in vitro reconstitution system for chemical engineering the peptidyl transferase center by introducing non-natural nucleosides at position A2451. This allowed us to investigate the peptidyl transfer reaction performed by a ribosome that contained a modified nucleoside at the active site. The main finding is that ribosomes carrying a 2'-deoxyribose at A2451 showed a compromised peptidyl transferase activity. In variance, adenine base modifications and even the removal of the entire nucleobase at A2451 had only little impact on peptide bond formation, as long as the 2'-hydroxyl was present. This implicates a functional or structural role of the 2'-hydroxyl group at A2451 for transpeptidation.

    This is the first monograph dealing with the applications of the Lie group analysis to the modeling equations governing internal wave propagation in the deep ocean. A new approach to describe the nonlinear interactions of internal waves in the ocean is presented. While the central idea of the book is to investigate oceanic internal waves through the prism of Lie group analysis, it is also shown for the first time that internal wave beams, representing exact solutions to the equation of motion of stratified fluid, can be found by solving the given model as invariant solutions of nonlinear equat

    This book addresses the need to improve TCP’s performance inside data centers by providing solutions that are both practical and backward compatible with standard TCP versions. The authors approach this challenge first by deriving an analytical model for TCP’s performance under typical data center workload traffic.  They then discuss some solutions that are designed to improve TCP performance by either proactively detecting network congestion through probabilistic retransmission or by avoiding timeout penalty through dynamic resizing of TCP segments. Experimental results show that each of techniques discussed outperforms standard TCP inside a data center.  ·         Analyzes the reasons behind TCP performance slump inside data centers when operating under synchronized workload traffic; ·         Introduces solutions to TCP performance slump inside data centers that are both practical and backward compatible; ·         Describes mechanisms that are responsible for TCP’s relia...

    Political communications in the form of unstructured text convey rich connotative meaning that can reveal underlying group social processes. Previous research has focused on sentiment analysis at the document level, but we extend this analysis to sub-document levels through a detailed analysis of affective relationships between entities extracted from a document. Instead of pure sentiment analysis, which is just positive or negative, we explore nuances of affective meaning in 22 affect categories. Our affect propagation algorithm automatically calculates and displays extracted affective relationships among entities in graphical form in our prototype (TEAMSTER), starting with seed lists of affect terms. Several useful metrics are defined to infer underlying group processes by aggregating affective relationships discovered in a text. Our approach has been validated with annotated documents from the MPQA corpus, achieving a performance gain of 74% over comparable random guessers.

    Full Text Available A novel quantum-behaved particle swarm optimization (QPSO algorithm, dual-group QPSO with different well centers (DWC-QPSO algorithm, is proposed by constructing the master-slave subswarms. The new algorithm was applied in the parameter optimization of on-ramp traffic PI controller combining with nonlinear feedback theory. With the critical information contained in the searching space and results of the basic QPSO algorithm, this algorithm avoids the rapid disappearance of swarm diversity and enhances the global searching ability through collaboration between subswarms. Experiment results on an on-ramp traffic control simulation show that DWC-QPSO can be well applied in the study of on-ramp traffic PI controller and the comparison results illustrate that DWC-QPSO outperforms other evolutionary algorithms with enhancement in both adaptability and stability.

    The guideline for the management of hepatocellular carcinoma (HCC) was first developed in 2003 and revised in 2009 by the Korean Liver Cancer Study Group and the National Cancer Center, Korea. Since then, many studies on HCC have been carried out in Korea and other countries. In particular, a substantial body of knowledge has been accumulated on diagnosis, staging, and treatment specific to Asian characteristics, especially Koreans, prompting the proposal of new strategies. Accordingly, the new guideline presented herein was developed on the basis of recent evidence and expert opinions. The primary targets of this guideline are patients with suspicious or newly diagnosed HCC. This guideline provides recommendations for the initial treatment of patients with newly diagnosed HCC.

    2015-09-01

    Full Text Available The literature points out a lack of studies describing practical experiences approaching the role of social participation, even though, the subject Brazilian Health System (SUS as a principle is valued by theoretical-conceptual works. The lack of studies is especially observed in mental health care services, where the existing studies focus on the users’ management engagement as part of psychosocial rehabilitation. Thus, this article introduces an experience developed in a Center for Psycho-Social Attention (CAPS, in the state of Mato Grosso do Sul, aiming to address the issue of social participation in care qualification, in accordance to legislation and technical standards. Thisstudy focused on two types of sources. 1 Internship Final Report of a Psycology Student including 54 sessions of a support group, 2 technical and legal documents concerning the SUS and the National Mental Health Policy and Humanization. The service aspects were analyzed through technical and legislative foundations - focusing the needs and claims on group discussions, classified as structure and process, used to assess the health care quality. Most concerns were listed on normative Ordinances and Regulations. Achieving social participation was not an institutional premise and, among the main difficulties was the medical/outpatient centered model and the representation of “crazy”/”CAPS users” as incapable. It requires: i integration of “clinic” and “politics”; ii intensification of interdisciplinary and psychological care; iii respect the citizenship of mental health users, and, finally, iv that the collective participation spaces do not exhaust themselves. Therefore, the collective participation spaces need practical recommendations in order to improve the structures and work processes and meet the users’ needs.

  10. Latent cluster analysis of ALS phenotypes identifies prognostically differing groups.

    Full Text Available BACKGROUND: Amyotrophic lateral sclerosis (ALS is a degenerative disease predominantly affecting motor neurons and manifesting as several different phenotypes. Whether these phenotypes correspond to different underlying disease processes is unknown. We used latent cluster analysis to identify groupings of clinical variables in an objective and unbiased way to improve phenotyping for clinical and research purposes. METHODS: Latent class cluster analysis was applied to a large database consisting of 1467 records of people with ALS, using discrete variables which can be readily determined at the first clinic appointment. The model was tested for clinical relevance by survival analysis of the phenotypic groupings using the Kaplan-Meier method. RESULTS: The best model generated five distinct phenotypic classes that strongly predicted survival (p<0.0001. Eight variables were used for the latent class analysis, but a good estimate of the classification could be obtained using just two variables: site of first symptoms (bulbar or limb and time from symptom onset to diagnosis (p<0.00001. CONCLUSION: The five phenotypic classes identified using latent cluster analysis can predict prognosis. They could be used to stratify patients recruited into clinical trials and generating more homogeneous disease groups for genetic, proteomic and risk factor research.

    The Pathosystems Resource Integration Center (PATRIC) is the bacterial Bioinformatics Resource Center (https://www.patricbrc.org). Recent changes to PATRIC include a redesign of the web interface and some new services that provide users with a platform that takes them from raw reads to an integrated analysis experience. The redesigned interface allows researchers direct access to tools and data, and the emphasis has changed to user-created genome-groups, with detailed summaries and views of the data that researchers have selected. Perhaps the biggest change has been the enhanced capability for researchers to analyze their private data and compare it to the available public data. Researchers can assemble their raw sequence reads and annotate the contigs using RASTtk. PATRIC also provides services for RNA-Seq, variation, model reconstruction and differential expression analysis, all delivered through an updated private workspace. Private data can be compared by ‘virtual integration’ to any of PATRIC's public data. The number of genomes available for comparison in PATRIC has expanded to over 80 000, with a special emphasis on genomes with antimicrobial resistance data. PATRIC uses this data to improve both subsystem annotation and k-mer classification, and tags new genomes as having signatures that indicate susceptibility or resistance to specific antibiotics.

    We reported a retrospective review of the urinary stone compositions in 12,846 patients. Data on urinary stone compositions analyzed between January 2003 and December 2012 in our center were collected. Infrared spectroscopy was used for stone analysis. Predominant stone component was recorded. Patients were divided into four age groups: 0-18, 19-40, 41-60, and 61-92, and five categories by components. In order to determine the change of stone characteristics with respect to time, data were also divided into two periods, 2003-2007 and 2008-2012. A total of 12,846 stones were included in this study. The age of the patients ranged from 1 to 92 years with 7,736 males and 5,110 females. Stone made of single component was rare, 2.61%. Calcium oxalate stone was the most common component at 82.56%. Calcium oxalate and uric acid stones were more common in male than in female. The incidence of calcium phosphate stones and uric acid stones had increased during the past 5 years, while calcium oxalate stones decreased. We found the highest incidence of stone disease in the 41-60 years old group and the lowest in the 1-18 years old for both genders. Calcium oxalate was the dominant component in every group but was more prevalent in 19-40 years group. The percentage of magnesium ammonium phosphate stone and uric acid stone increased with age.

    In previous studies, increased ventilation rates and reduced indoor carbon dioxide concentrations have been associated with improvements in health at work and increased performance in work-related tasks. Very few studies have assessed whether ventilation rates influence performance of real work. This paper describes part one of a two-part analysis from a productivity study performed in a call center operated by a health maintenance organization. Outside air ventilation rates were manipulated, indoor air temperatures, humidities, and carbon dioxide concentrations were monitored, and worker performance data for advice nurses, with 30-minute resolution, were analyzed via multivariate linear regression to look for an association of performance with building ventilation rate, or with indoor carbon dioxide concentration (which is related to ventilation rate per worker). Results suggest that the effect of ventilation rate on worker performance in this call center was very small (probably less than 1%) or nil, over most of the range of ventilation rate experienced during the study (roughly 12 L s{sup -1} to 48 L s{sup -1} per person). However, there is some evidence suggesting performance improvements of 2% or more when the ventilation rate per person is very high, as indicated by indoor CO{sub 2} concentrations exceeding outdoor concentrations by less than 75 ppm.

The organizational structures of the EOCs were standardized, scalable and flexible. Incident Command System was the widely applied organizational structure with a strong preference. The EOCs were managed by a unit of emergency management during routine time and surge staff were engaged upon emergencies. The selected EOCs had clear information management framework including information collection, assessment and dissemination.Conclusions:The performance of National Health Emergency Response Command Center can be improved by learning from the good practice of the selected EOCs, including setting clear functions, standardizing the organizational structure, enhancing the human resource capacity and strengthening information management.

  18. Groups as units of functional analysis, individuals as proximate mechanisms.

    2014-06-01

    Whenever selection operates at a given level of a multitier hierarchy, units at that level should become the object of functional analysis, and units at lower levels should be studied as proximate mechanisms. This intuition already exists for the study of genes in individuals, when individuals are the unit of selection. It is only beginning to be applied for the study of individuals in groups, when groups are the unit of selection. Smaldino's target article is an important step in this direction with an emphasis on human cultural evolution, but the same algorithm applies to all multilevel evolutionary processes.

    In recent years, parents have become more disparaging towards childhood vaccination. One group that is critical about the National Immunization Program (NIP) and participates less comprises parents with an anthroposophical worldview. Despite the fact that various studies have identified anthroposophists as critical parents with lower vaccination coverage, no research has been done to explore the beliefs underlying their childhood vaccination decision-making. We conducted a qualitative study using three focus groups (n = 16) of parents who visit an anthroposophical child welfare center. Our findings show that participants did not refuse all vaccinations within the Dutch NIP, but mostly refused the Mumps, Measles, and Rubella (MMR) vaccination. Vaccination decisions are influenced by participants' lifestyle, perception of health, beliefs about childhood diseases, perceptions about the risks of diseases, perceptions about vaccine effectiveness and vaccine components, and trust in institutions. Parents indicated that they felt a need for more information. Sufficient references should be provided to sources containing more information about childhood vaccination, especially about the effectiveness of vaccines and vaccine components and the risks, such as possible side effects and benefits of vaccination. This may satisfy parents' information needs and enable them to make a sufficiently informed choice whether or not to vaccinate their child.

    Full Text Available The article is devoted to the phase analysis as a tool preprocessor analysis of a multi-purpose center. Consider the time series of the daily number of requests received on the basis of the phase portraits of these time series. These time series have strong properties of cycles and periodicity. Practice has shown that in modern conditions, for example, for the Russian economy with its instability and financial crises, classical economic theory and statistics, built on linear models, turned out to be unproductive. Overview of approaches and economic-mathematical methods preprocessor analysis of evolutionary economic processes and the corresponding time series allows concluding the following: one versatile, satisfying all the requirements, do not possess the shortcomings of the method of analysis and forecasting does not exist. Each approach and each method has its advantages, disadvantages, limits of use. Most of the known methods of forecasting operate detected in the considered time series properties of cycles and periodicity. Thus, the mere presence of a pronounced cyclicity at different levels of the considered hierarchical model of the time series of the number of requests in a multi-purpose center are important indicators of the possibility of constructing an adequate predictive model number of requests in the multi-purpose centre

    "To understand and protect our home planet, to explore the universe and search for life, and to inspire the next generation of explorers" is NASA's mission. The Systems Management Office at Johnson Space Center (JSC) is searching for methods to effectively manage the Center's resources to meet NASA's mission. D-Side is a group multi-criteria decision support system (GMDSS) developed to support facility decisions at JSC. D-Side uses a series of sequential and structured processes to plot facilities in a three-dimensional (3-D) graph on the basis of each facility alignment with NASA's mission and goals, the extent to which other facilities are dependent on the facility, and the dollar value of capital investments that have been postponed at the facility relative to the facility replacement value. A similarity factor rank orders facilities based on their Euclidean distance from Ideal and Nadir points. These similarity factors are then used to allocate capital improvement resources across facilities. We also present a parallel model that can be used to support decisions concerning allocation of human resources investments across workforce units. Finally, we present results from a pilot study where 12 experienced facility managers from NASA used D-Side and the organization's current approach to rank order and allocate funds for capital improvement across 20 facilities. Users evaluated D-Side favorably in terms of ease of use, the quality of the decision-making process, decision quality, and overall value-added. Their evaluations of D-Side were significantly more favorable than their evaluations of the current approach.

    2015-01-01

    The calculation of common factor means in structured means analysis (SMM) is considered. The SMM equations imply that the unique factors are defined as having zero means. It was shown within the one factor solution that this definition implies larger absolute common factor loadings to co-occur with larger absolute expectations of the observed variables in the single group case. This result was illustrated by means of a small simulation study. It is argued that the proportionality of factor lo...

    We present a new nearby young moving group (NYMG) kinematic membership analysis code, LocAting Constituent mEmbers In Nearby Groups (LACEwING), a new Catalog of Suspected Nearby Young Stars, a new list of bona fide members of moving groups, and a kinematic traceback code. LACEwING is a convergence-style algorithm with carefully vetted membership statistics based on a large numerical simulation of the Solar Neighborhood. Given spatial and kinematic information on stars, LACEwING calculates membership probabilities in 13 NYMGs and three open clusters within 100 pc. In addition to describing the inputs, methods, and products of the code, we provide comparisons of LACEwING to other popular kinematic moving group membership identification codes. As a proof of concept, we use LACEwING to reconsider the membership of 930 stellar systems in the Solar Neighborhood (within 100 pc) that have reported measurable lithium equivalent widths. We quantify the evidence in support of a population of young stars not attached to any NYMGs, which is a possible sign of new as-yet-undiscovered groups or of a field population of young stars.

    Cross-correlation analysis and wavelet transform methods are proposed to investigate the phase relationship between the monthly sunspot group numbers in the solar northern and southern hemispheres.It is found that (1) the monthly sunspot group numbers in the northern hemisphere begin two months earlier than those in the southern one,which should lead to phase asynchrony between them but with a slight effect; (2) the Schwabe cycle length for the monthly sunspot group numbers in the two hemispheres obviously differs from each other,and the mean Schwabe cycle length of the monthly sunspot group numbers in the northern hemisphere is slightly larger than that in the southern one; (3) the monthly sunspot group numbers in the northern hemisphere precede those in the southern hemisphere during the years of about 1874-1927,after which,the southern hemisphere leads the northern hemisphere in the years 1928-1964,and then the northern hemisphere leads in time till the present.

    2015-12-01

    Full Text Available This paper is based on the analysis of a focus group interview of a moderator and a group of undergraduate students on the topic of self-regulation of learning. The purpose of the investigation was to identify interaction patterns that appeared in the talk of participants and the moderator. In the stream of communication two rudimentary interaction patterns were recognized. The first pattern was named the Catalogue. It consists of a sequence of turns of participants who respond to a request of the moderator and who provide their answers, one by one, without reacting on the content of the previous partner(s talk. The other interaction pattern was called the Domino. In this pattern participants respond to each other. The Catalogue pattern prevailed in the interview. Alongside with identification of patterns of interaction the study demonstrated the functions of the common ground and its accomplishment in the talk of the moderator and participants.

  14. Discrete Fourier Analysis and Chebyshev Polynomials with G2 Group

    Directory of Open Access Journals (Sweden)

    Huiyuan Li

    2012-10-01

    Full Text Available The discrete Fourier analysis on the 30°-60°-90° triangle is deduced from the corresponding results on the regular hexagon by considering functions invariant under the group G2, which leads to the definition of four families generalized Chebyshev polynomials. The study of these polynomials leads to a Sturm-Liouville eigenvalue problem that contains two parameters, whose solutions are analogues of the Jacobi polynomials. Under a concept of m-degree and by introducing a new ordering among monomials, these polynomials are shown to share properties of the ordinary orthogonal polynomials. In particular, their common zeros generate cubature rules of Gauss type.

    We find new exact solutions of the Einstein field equations for a perfect fluid metric conformal to a spacetime of type D in the Petrov classification scheme. We analyse the complete system of equations using Lie group analysis. While previous work was confined to conformal factors of the form U = U(t, x), we investigate the complete situation U = U(t, x, y, z) as well as an auxiliary integrability condition. New classes of solutions are generated via the symmetry generators. The resulting solutions are examined for physical plausibility. Expressions for the energy density and pressure are obtained explicitly and empirical results suggest that these dynamical quantities are positive as expected.

    Aguilar, A C; Papavassiliou, J

    2014-01-01

    In the present work we carry out a systematic study of the renormalization properties of the integral equation that determines the momentum evolution of the effective gluon mass. A detailed, all-order analysis of the complete kernel appearing in this particular equation reveals that the renormalization procedure may be accomplished through the sole use of ingredients known from the standard perturbative treatment of the theory, with no additional assumptions. However, the subtle interplay of terms operating at the level of the exact equation gets distorted by the approximations usually employed when evaluating the aforementioned kernel. This fact is reflected in the form of the obtained solutions, whose deviations from the correct behavior are best quantified by resorting to appropriately defined renormalization-group invariant quantities. This analysis, in turn, provides a solid guiding principle for improving the form of the kernel, and furnishes a well-defined criterion for discriminating between various p...

    Dynamic renormalization group (RNG) analysis is applied to the investigation of the behavior of the infrared limits of weakly rotating turbulence. For turbulent How subject to weak rotation, the anisotropic part in the renormalized propagation is considered to be a perturbation of the isotropic part. Then, with a low-order approximation, the coarsening procedure of RNG transformation is performed. After implementing the coarsening and rescaling procedures, the RNG analysis suggests that the spherically averaged energy spectrum has the scaling behavior E(k) ∝ k11/5 for weakly rotating turbulence. It is also shown that the Coriolis force will disturb the stability of the Kolmogorov -5/3 energy spectrum and will change the scaling behavior even in the case of weak rotation.%Dynamic renormalization group(RNG)analysis is applied to the investigation of the behavior of the infrared limits of weakly rotating turbulence.For turbulent flow subject to weak rotation,the anisotropic part in the renormalized propagation is considered to be a perturbation of the isotropic part.Then,with a low-order approximation,the coarsening procedure of RNG transformation is performed.After implementing the coarsening and rescaling procedures,the RNG analysis suggests that the spherically averaged energy spectrum has the scaling behavior E(k)∝ k-11/5 for weakly rotating turbulence.It is also shown that the Coriolis force will disturb the stability of the Kolmogorov-5/3 energy spectrum and will change the scaling behavior even in the case of weak rotation.

    Health information technology (IT) has opened exciting avenues for capturing, delivering and sharing data, and offers the potential to develop cost-effective, patient-focused applications. In recent years, there has been a proliferation of health IT applications such as outpatient portals. Rigorous evaluation is fundamental to ensure effectiveness and sustainability, as resistance to more widespread adoption of outpatient portals may be due to lack of user friendliness. Health IT applications that integrate with the existing electronic health record and present information in a condensed, user-friendly format could improve coordination of care and communication. Importantly, these applications should be developed systematically with appropriate methodological design and testing to ensure usefulness, adoption, and sustainability. Based on our prior work that identified numerous information needs and challenges of HCT, we developed an experimental prototype of a health IT tool, the BMT Roadmap. Our goal was to develop a tool that could be used in the real-world, daily practice of HCT patients and caregivers (users) in the inpatient setting. Herein, we examined the views, needs, and wants of users in the design and development process of the BMT Roadmap through user-centered Design Groups. Three important themes emerged: 1) perception of core features as beneficial (views), 2) alerting the design team to potential issues with the user interface (needs); and 3) providing a deeper understanding of the user experience in terms of wider psychosocial requirements (wants). These findings resulted in changes that led to an improved, functional BMT Roadmap product, which will be tested as an intervention in the pediatric HCT population in the fall of 2015 (ClinicalTrials.govNCT02409121).

    Full Text Available High growth-rate of plantlet is the integral index of intensity of physiological processes at rice and other cultures. 20 typical plantlets from each of two variants were studded (in the distilled water in thermostat at a temperature 29° C by: length of embryonic root and coleoptile. Comparative analysis of trait characterizing the growth rates of rice varieties showed reliable advantage of Russian ones above the Italian and Chinese. Local varieties, regionalized until the year 2000, exceed new ones on this trait. Highest growth rates were characterized by medium grain samples. The white grain and red grain varieties are excelled other groups on the height of plantlet. Analysis rates of height of plantlets in the distinguished groups showed the necessity of prosecution of improvement of the above enumerated signs at the varieties of late term of ripening, long grain, with Waxy gene, colored grain. We recommend to sow this type of varieties on fields with good leveling, because of low speed of growth

    2016-01-01

    We present elemental abundances for all seven stars in Moving Group W11450 (Latham 1) to determine if they may be chemically related. These stars appear to be both spatially and kinematically related, but no spectroscopic abundance analysis exists in literature. Abundances for eight elements were derived via equivalent width analyses of high resolution (R $\\sim$60,000), high signal-to-noise ratio ($\\langle$SNR$\\rangle\\sim$100) spectra obtained with the Otto Struve 2.1m telescope and Sandiford Echelle Spectrograph at McDonald Observatory. The large star-to-star scatter in metallicity, -0.55 $\\leq$ [Fe/H] $\\leq$ 0.06 dex ($\\sigma$= 0.25), implies these stars were not produced from the same chemically homogeneous molecular cloud, and are therefore not part of a remnant or open cluster as previously proposed. Prior to this analysis, it was suggested that two stars in the group, W11449 & W11450, are possible wide binaries. The candidate wide binary pair show similar chemical abundance patterns with not only ir...

    Full Text Available Network Text Analysis (NTA is a term used to describe a variety of software - supported methods for modeling texts as networks of concepts. In this study we apply NTA to the screenplay of American Sniper, an Academy Award nominee for Best Adapted Screenplay in 2014. Specifically, we est ablish prior expectations as to the key themes associated with war films. We then empirically test whether words associated with the most influentially - positioned nodes in the network signify themes common to the war - film genre. As predicted, we find tha t words and concepts associated with the least constrained nodes in the text network were significantly more likely to be associated with the war genre and significantly less likely to be associated with genres to which the film did not belong.

    Full Text Available Purpose: BCR-ABL kinase domain (KD mutations account for 50-90% of the imatinib resistance observed in patients of CML-chronic phase. In CML-CP patients receiving imatinib first-line, mutation analysis is recommended in case of failure or suboptimal response using European LeukemiaNet (ELN criteria. The present study was carried out at a tertiary oncology centre in south India to assess which mutations accounted for resistance to imatinib among patients of chronic phase CML being treated with imatinib.Methods: This was a retrospective observational study. We analyzed patients who were tested for imatinib resistance mutation in view of suboptimal responses while on imatinib or imatinib failure. Direct sequencing of the BCR-ABL transcript by the Sanger method was used for IRMA testing.Results: Out of 120 tested for IRMA, 36 (30% had detectable mutations. We observed a higher frequency of mutations at amino acids T315, F359 and M351T.Conclusions: Among the patients who were tested for imatinib resistance mutation in view of suboptimal responses while on imatinib or imatinib failure, 30% had IRMA +ve mutations. The high incidence of imatinib resistance in present study may be attributed to the fact that our patients were given higher dose of imatinib (600 mg, if they failed to achieve CCyR at 12 months or CHR at 3 months as they could not afford second generation TKIs.

In order to provide key insights to the United Nations Children's Fund (UNICEF) and the World Health Organization (WHO) supply chain hub - as well as other players, including national EPI - a landscape analysis study was conducted from September 2015 to February 2016. This is a cross-sectional survey taken by 43 countries that combines qualitative and quantitative approaches. Data was collected through a desk review, consultation, interviews, and distance questioning. References and guidance were used to determine and specify the underlying mechanisms of NLWGs. The key findings are:This study has provided a general overview of the status of NLWGs for immunization in various countries. Based on the key insights of the study, technical assistance needs have been identified, and immunization partners will be required to help countries create and reinforce their NLWGs.

  15. Renormalization group analysis of the gluon mass equation

    2014-04-01

    We carry out a systematic study of the renormalization properties of the integral equation that determines the momentum evolution of the effective gluon mass in pure Yang-Mills theory, without quark effects taken into account. A detailed, all-order analysis of the complete kernel appearing in this particular equation, derived in the Landau gauge, reveals that the renormalization procedure may be accomplished through the sole use of ingredients known from the standard perturbative treatment of the theory, with no additional assumptions. However, the subtle interplay of terms operating at the level of the exact equation gets distorted by the approximations usually employed when evaluating the aforementioned kernel. This fact is reflected in the form of the obtained solutions, for which the deviations from the correct behavior are best quantified by resorting to appropriately defined renormalization-group invariant quantities. This analysis, in turn, provides a solid guiding principle for improving the form of the kernel, and furnishes a well-defined criterion for discriminating between various possibilities. Certain renormalization-group inspired Ansätze for the kernel are then proposed, and their numerical implications are explored in detail. One of the solutions obtained fulfills the theoretical expectations to a high degree of accuracy, yielding a gluon mass that is positive definite throughout the entire range of physical momenta, and displays in the ultraviolet the so-called "power-law" running, in agreement with standard arguments based on the operator product expansion. Some of the technical difficulties thwarting a more rigorous determination of the kernel are discussed, and possible future directions are briefly mentioned.

    Full Text Available Purpose : Through a clinical and retrospective analysis of pediatric patients who visited the Regional Emergency Medical Center of Masan Samsung Hospital from January 2007 to December 2008, we characterized pediatric and adolescent emergency patients to improve emergency care in future. Methods : We reviewed the medical records of 14,065 pediatric patients below 19 years of age. Results : The male to female ratio was 1.5:1, and the most common age group was less than 3 years (49.6%. The peak month was May (10.0%, the peak day of the week was Sunday (24.7%, and the peak time of day was 20:00&#8211;20:59 (8.5%. There was no difference in the number of visits per day based on weather (sunny, rain [below 10 mm per day], snow, and fog or daily temperature difference; however, visits increased on sandy, dusty days and decreased on rainy days with more than 10 mm of rain per day. Based on the international classification of disease (ICD-10 system, the most common disease code was code R (symptoms, sign, and abnormal clinical laboratory finding (31.5%, and the most common symptom was fever (13.1%. Final outcomes were discharged (73.8%, admitted (25.7%, transferred (0.4%, and expired (0.1%. In adolescent patients aged 15&#8211;19 years, the most common disease code was Injury & Poisoning (code S&T, 36.9%; the most common symptom was abdominal pain (9.6%. Conclusion : Pediatric patients visiting the emergency center were most likely to be male and under 3 years of age and to visit between 20:00 and 21:00 on Sundays and in May, and the most common symptom was fever. Differences between adolescents and pediatric patients showed that adolescents had a higher visiting rate with abdominal pain and a larger temperature difference.

    2016-03-01

    Previous studies have identified healthcare practices that may place undue pressure on related donors (RDs) of hematopoietic cell products and an increase in serious adverse events associated with morbidities in this population. As a result, specific requirements to safeguard RD health have been introduced to Foundation for the Accreditation of Cellular Therapy/The Joint Accreditation Committee ISCT and EBMT (FACT-JACIE) Standards, but the impact of accreditation on RD care has not previously been evaluated. A survey of transplant program directors of European Group for Blood and Marrow Transplantation member centers was conducted by the Donor Health and Safety Working Committee of the Center for International Blood and Marrow Transplant Research to test the hypothesis that RD care in FACT-JACIE accredited centers is more closely aligned with international consensus donor care recommendations than RD care delivered in centers without accreditation. Responses were received from 39% of 304 centers. Our results show that practice in accredited centers was much closer to recommended standards as compared with nonaccredited centers. Specifically, a higher percentage of accredited centers use eligibility criteria to assess RDs (93% versus 78%; P = .02), and a lower percentage have a single physician simultaneously responsible for an RD and their recipient (14% versus 35%; P = .008). In contrast, where regulatory standards do not exist, both accredited and nonaccredited centers fell short of accepted best practice. These results raise concerns that despite improvements in care, current practice can place undue pressure on donors and may increase the risk of donation-associated adverse events. We recommend measures to address these issues through enhancement of regulatory standards as well as national initiatives to standardize RD care.

    The Data Analysis Center (DAC) of the Center for Nuclear Studies (CNS) at the George Washington University (GW) has made significant progress in its program to enhance and expand the partial-wave (and multipole) analyses of fundamental two- and three-body reactions (such as pion-nucleon, photon-nucleon, and nucleon-nucleon scattering) by maintaining and augmenting the analysis codes and databases associated with these reactions. These efforts provide guidance to experimental groups at the international level, forming an important link between theory and experiment. A renaissance in light hadron spectroscopy is underway as a continuous stream of polarization data issues from existing precision electromagnetic facilities and the coming Jefferson Lab 12 GeV Upgrade. Our principal goals have been focused on supporting the national N* resonance physics program. We have also continued to study topics more generally related to the problems associated with partial-wave analysis. On the Experimental side of the CNS DAC. Its primary goal is the enhancement of the body of data necessary for our analyses of fundamental γ - N reactions. We perform experiments that study the dynamics responsible for the internal structure of the nucleon and its excitations. Our principal focus is on the N* programs at JLab and MAMI. At JLab we study spin-polarization observables using polarized photons, protons and neutrons and yielding charged final states. Similarly at MAMI we study neutral meson photoproduction off polarized protons and neutrons. We use the Crystal Ball and TAPS spectrometers (CBT) to detect photons and neutrons to measure the photoproduction of π0, η, 2π0, π0η, and K0 off the neutron. The CBT program complements our program at JLab, which studies reactions resulting in charged final states. We are also involved in a renewed effort to make neutral pion photoproduction measurements close to threshold at Mainz. In addition to the programs underway, we are contributing to

    Over the past decade researchers working on the rocks of the Beaufort Group in the main Karoo Basin of South Africa have vastly increased our understanding of this important Permo-Triassic sequence. Many new fossil forms have been discovered, allowing for breakthroughs into the biodiversity, biogeography and biostratigraphy of the group. Taxonomic and phylogenetic advances are many and varied, and cover most of the vertebrate taxa, but with emphasis placed on the temnospondyl amphibians, archosauriforms and non-mammalian synapsids, in particular the anomodontia. Biostratigraphic breakthroughs have centered on the Middle Permian Eodicynodon and Tapinocephalus assemblage zones, the Late Permian Dicynodon Assemblage Zone, and the Triassic Lystrosaurus and Cynognathus assemblage zones. Correlation of these biozones with better dated sequences in Europe, Russia and China has allowed for many chronostratigraphic refinements, which are in turn vital for sequence stratigraphical analysis of the basin fill. Based on fossil data, both the lower (Ecca-Beaufort) and upper (Beaufort-Molteno) contacts of the group have been proved to be highly diachronous. The refined chronostratigraphic framework has also allowed for a better analysis of the basin evolution through time, particularly in terms of the correlation of external stimuli that affect basin sedimentation patterns.

    Although numerous studies have analyzed the relationship between manual material handling (MMH) and the forces acting on the lumbar spine, the difference in the MMH between experts and novices through the analysis of measured data has not been well studied. The purpose of this paper was to analyze the difference in the MMH positions between ten skilled experts working at a freight transport company (Group 1) and five unskilled novices without any experience (Group 2) during asymmetric lifting. All the human subjects performed asymmetric lifting experiments with closed eyes; the experiments involved moving loads (6 and 18 kg) to the left side. Time series data of the vertical ground reaction force were measured, using a Wii Balance Board, and then, the center-of-pressure (CoP) trajectories were calculated. The balance board was used for the measurement, because it was reliable, inexpensive, and portable and provided good repeatability even on rough surfaces, and all the information pertaining to the load and worker under various conditions was captured without any omissions. Under the 18 kg load condition, the CoP positions for Group 2 were located on the same side during left asymmetric lifting; however, those for Group 1 were located on the opposite side during left asymmetric lifting (\\documentclass[12pt]{minimal} \\usepackage{amsmath} \\usepackage{wasysym} \\usepackage{amsfonts} \\usepackage{amssymb} \\usepackage{amsbsy} \\usepackage{upgreek} \\usepackage{mathrsfs} \\setlength{\\oddsidemargin}{-69pt} \\begin{document} }{}$P measurement results, we inferred that the difference in the CoP positions between the two different groups could be attributed to the difference in the hip positions. Most skilled experts position their hips in such a way that their CoP trajectories move toward the opposite side during left asymmetric lifting. Although the skillful characteristics of experts may be responsible for the lightening of the burden on the waist during asymmetric

    The International GNSS Service (IGS) Tide Gauge Benchmark Monitoring (TIGA) Working Group (WG) has recently finallized their reprocessing campaign, using all relevant Global Positioning System (GPS) observations from 1995 to 2014. This re-processed dataset will provide high quality estimates of land motions, enabling regional and global high-precision geophysical/geodeticstudies. Several of the individual TIGA Analysis Centers (TACs) have completed processing the full history of GPS observations recorded by the IGS global network, as well as, many other GPS stationsat or close to tide gauges, which are available from the TIGA data centre at the University of La Rochelle (www.sonel.org). The TAC solutions contain a total of over 700 stations. Following the recentimprovements in processing models and strategies, this is the first complete reprocessing attempt by the TIGA WG to provide homogeneous position time series. The TIGA Combination Centre (TCC) atthe University of Luxembourg (UL) has computed a first multi-year weekly combined solution using two independent combination software packages: CATREF and GLOBK. These combinations allow anevaluation of any effects from the combination software and of the individual TAC contributions and their influences on the combined solution. In this study we will present the first UL TIGA multi-yearcombination results and discuss these in terms of geocentric sea level changes.

    To provide retrospective, descriptive information on patients with cervical necrotizing fasciitis treated at a single center during the years 1998-2014, and to evaluate the outcome of a newly introduced treatment strategy. Retrospective analysis of clinical data obtained from medical records. Mortality, pre-morbidity, severity of illness, primary site of infection, type of bacteria, time parameters. The observed 3-month mortality was 6/59 (10 %). The most common initial foci of the infection were pharyngeal, dental or hypopharyngeal. The most common pathogen was Streptococcus milleri bacteria within the Streptococcus anginosus group (66 % of the cases). Using a combined treatment with early surgical debridement combined with hyperbaric oxygen treatment, it is possible to reduce the mortality rate among patients suffering from cervical necrotizing fasciitis, compared to the expected mortality rate and to previous historical reports. Data indicated that early onset of hyperbaric oxygen treatment may have a positive impact on survival rate, but no identifiable factor was found to prognosticate outcome.

  6. The 2-Methoxy Group Orientation Regulates the Redox Potential Difference between the Primary (QA) and Secondary (QB) Quinones of Type II Bacterial Photosynthetic Reaction Centers

    Science.gov (United States)

    2015-01-01

    Recent studies have shown that only quinones with a 2-methoxy group can act simultaneously as the primary (QA) and secondary (QB) electron acceptors in photosynthetic reaction centers from purple bacteria such as Rb. sphaeroides. 13C HYSCORE measurements of the 2-methoxy group in the semiquinone states, SQA and SQB, were compared with DFT calculations of the 13C hyperfine couplings as a function of the 2-methoxy dihedral angle. X-ray structure comparisons support 2-methoxy dihedral angle assignments corresponding to a redox potential gap (ΔEm) between QA and QB of 175–193 mV. A model having a methyl group substituted for the 2-methoxy group exhibits no electron affinity difference. This is consistent with the failure of a 2-methyl ubiquinone analogue to function as QB in mutant reaction centers with a ΔEm of ∼160–195 mV. The conclusion reached is that the 2-methoxy group is the principal determinant of electron transfer from QA to QB in type II photosynthetic reaction centers with ubiquinone serving as both acceptor quinones.

  13. The Renormalization-Group Method Applied to Asymptotic Analysis of Vector Fields

    CERN Document Server

    Kunihiro, T

    1996-01-01

    The renormalization group method of Goldenfeld, Oono and their collaborators is applied to asymptotic analysis of vector fields. The method is formulated on the basis of the theory of envelopes, as was done for scalar fields. This formulation actually completes the discussion of the previous work for scalar equations. It is shown in a generic way that the method applied to equations with a bifurcation leads to the Landau-Stuart and the (time-dependent) Ginzburg-Landau equations. It is confirmed that this method is actually a powerful theory for the reduction of the dynamics as the reductive perturbation method is. Some examples for ordinary diferential equations, such as the forced Duffing, the Lotka-Volterra and the Lorenz equations, are worked out in this method: The time evolution of the solution of the Lotka-Volterra equation is explicitly given, while the center manifolds of the Lorenz equation are constructed in a simple way in the RG method.

    Group key exchange protocols are basic protocols to provide privacy and integrity in secure group communication. This paper discusses the security of one type of group key exchange protocols and defines the kind of protocols as broadcaster group protocols. It points out two attacks on this kind of protocols. The first attack can be avoided by using fresh values in each action during one session of the group protocol. The second attack should be related with concrete application. It also proposes a dynamic key agreement protocol as an example of solutions at the last part of the paper.

We herein provide a comparative analysis between alemtuzumab and basiliximab induction therapy and correlate lymphocyte depletion and recovery with the clinical course after KTx. This is a single center retrospective analysis of 225 patients/consecutive kidney transplantations treated with alemtuzumab for lymphocyte depletion and 205 recipients treated with basiliximab. Mean lymphocyte counts were 22.8 ± 9.41% before Tx and 2.61 ± 3.11% between week 1 and week 3 in the alemtuzumab group and 23.77 ± 10.42% before Tx and 13.92 ± 8.20% in the basiliximab group. Delayed graft function (DGF, cytomegalovirus (CMV status, and recipient age showed a significant correlation with lymphocyte counts in the alemtuzumab group only. The outcome was read in reference to the velocity of lymphocyte recovery and in comparison to the control group. Lymphocyte counts early after transplantation, following alemtuzumab treatment, could be identified as a predictive factor for kidney function early after transplantation. A detailed analysis of phenotype and function of lymphocytes after alemtuzumab induction together with a correlation with the clinical course is warranted.

    This article aims to characterize the different types of Facebook and Twitter groups for different mental diseases, their purposes, and their functions. We focused the search on depressive disorders, dementia, and Alzheimer's and Parkinson's diseases and examined the Facebook (www.facebook.com) and Twitter (www.twitter.com) groups. We used four assessment criteria: (1) purpose, (2) type of creator, (3) telehealth content, and (4) free-text responses in surveys and interviews. We observed a total of 357 Parkinson groups, 325 dementia groups, 853 Alzheimer groups, and 1127 depression groups on Facebook and Twitter. Moreover, we analyze the responses provided by different users. The survey and interview responses showed that many people were interested in using social networks to support and help in the fight against these diseases. The results indicate that social networks are acceptable by users in terms of simplicity and utility. People use them for finding support, information, self-help, advocacy and awareness, and for collecting funds.

    1999-03-01

    Once again, the most recent fiscal year was a productive one for the Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory (ORNL), as well as a year for change. The FY 1998 in Review section in this report summarizes quite a few new and updated data and information products, and the ''What's Coming in FY 1999'' section describes our plans for this new fiscal year. During FY 1998, CDIAC began a data-management system for AmeriFlux, a long-term study of carbon fluxes between the terrestrial biosphere of the Western Hemisphere and the atmosphere. The specific objectives of AmeriFlux are to establish an infrastructure for guiding, collecting, synthesizing, and disseminating long-term measurements of CO{sub 2}, water, and energy exchange from a variety of ecosystems; collect critical new information to help define the current global CO{sub 2} budget; enable improved predictions of future concentrations of atmospheric CO{sub 2}; and enhance understanding of carbon fluxes. Net Ecosystem Production (NEP), and carbon sequestration in the terrestrial biosphere. The data-management system, available from CDIAC'S AmeriFlux home page (http://cdiac.esd.ornl.gov/programs/ameriflux/ ) is intended to provide consistent, quality-assured, and documented data across all AmeriFlux sites in the US, Canada, Costa Rica, and Brazil. It is being developed by Antoinette Brenkert and Tom Boden, with assistance from Susan Holladay (who joined CDIAC specifically to support the AmeriFlux data-management effort).

    2002-01-01

    A comprehensive study on compactness has been carried out on the 2dF Galaxy Group Catalogue constructed by Merch\\'an & Zandivarez. The compactness indexes defined in this work take into account different geometrical constraints in order to explore a wide range of possibilities. Our results show that there is no clear distinction between groups with high and low level of compactness when considering particular properties as the radial velocity dispersion, the relative fraction of galaxies per spectral type and luminosity functions of their galaxy members. Studying the trend of the fraction of galaxies per spectral type as a function of the dimensionless crossing time some signs of dynamical evolution are observed. From the comparison with previous works on compactness we realize that special care should be taken into account for some compactness criteria definitions in order to avoid possible biases in the identification.

    Full Text Available Hip joint is one of the most stable joints in human body. It has intrinsic stability provided by its relatively rigid ball and socket configuration. The hip joint also has a wide range of motion, which allows normal locomotion and daily activities. Location of hip joint center (HJC is an important parameter in gait analysis, biomechanical and clinical research laboratories to calculate human lower extremity kinematics and kinetics. Inaccuracies in estimation of hip joint center are shown to propagate errors in kinematic and kinetic calculations of lower extremities

  7. Entrepreneurial networking differences: An ethnic in-group and out-group analysis

    Directory of Open Access Journals (Sweden)

    Boris Urban

    2011-03-01

    Full Text Available Orientation: Researching entrepreneurship using a network perspective is important, as social networks are assets for small business owners struggling to survive in competitive markets.Research purpose: The research question of this study has focused on what we can learn about entrepreneurial networking, considering that there is an under-explored and unarticulated set of networking principles and practices which have not been previously analysed in terms of a multiethnic country context.Motivation for the study: Often the lack of network use is reported as a feature of entrepreneurs, who have less opportunity to utilise formal social capital features. Social networks provided by extended family, community-based or organisational relationships are often theorised to supplement the effects of education, experience and financial capital.Research design, approach and method: Based on hypothesised differences in networking ties, network assistance and support relationships, a survey was used to collect data on quantitative measures. Descriptive statistics were calculated and differential tests were conducted to test the hypotheses.Main findings: Results indicate that entrepreneurial networking is largely independent on group composition. Generally at least some aspects of networking are generic and as a consequence, a more integrated view of networking can be adopted.Practical/managerial implications: The practical value of the present study points to several areas of interest to entrepreneurs, policy makers and educators, through demonstrating the multifaceted nature of entrepreneurial networks for different groups and their explanatory potential in understanding networking.Contribution/value-add: Despite the importance of entrepreneurial networking, little empirical or theoretical research has examined the dynamics of networking in a developing country context such as South Africa, which has lower than expected total entrepreneurship activity.

    1989-11-01

    The University of Cincinnati is working with the Westinghouse Materials Company of Ohio (WMCO) to develop remedial action residual radioactive material soil guidelines for the Feed Materials Production Center (FMPC). As a first step in developing these soil guidelines, a radiological environmental pathway screening analysis was performed. The purpose of the pathway screening analysis was to identify the radionuclides and environmental pathways that would lead to the highest exposure or dose to humans from residual radioactivity in the soil at the FMPC. In addition, the screening analysis identifies those pathways that are critical to a particular radioisotope.

    Recently the International GNSS Service (IGS) Tide Gauge Benchmark Monitoring (TIGA) Working Group (WG) has completed their repro2 solutions by re-analyzing the full history of all relevant Global Positioning System (GPS) observations from 1995 to 2015. This re-processed data set will provide high-quality estimates of vertical land movements for more than 500 stations, enabling regional and global high-precision geophysical/geodetic studies. All the TIGA Analysis Centres (TACs) have processed the observations recorded by GPS stations at or close to tide gauges, which are available from the TIGA Data Center at the University of La Rochelle (www.sonel.org) besides those of the global IGS core network used for its reference frame implementations. Following the recent improvements in processing models, strategies (http://acc.igs.org/reprocess2.html), this is the first complete re-processing attempt by the TIGA WG to provide homogeneous position time series relevant to sea level changes. In this study we report on a first multi-year daily combined solution from the TIGA Combination Centre (TCC) at the University of Luxembourg (UL) with respect to the latest International Terrestrial Reference Frame (ITRF2014). Using two independent combination software packages, CATREF and GLOBK, we have computed a first daily combined solution from TAC solutions already available to the TIGA WG. These combinations allow an evaluation of any effects from the combination software and of the individual TAC parameters and their influences on the combined solution with respect to the latest ITRF2014. Some results of the UL TIGA multi-year combinations in terms of geocentric sea level changes will be presented and discussed.

    Increasing heat generation in CPUs can hamper effective recirculation and by pass because of the large temperature difference between the exhaust and the intake air through a server room. This increases the overall temperature inside a data center and decreases the efficiency of the data center's cooling system. The purpose of the data center's cooling system is to separate the intake and exhaust air by controlling the computer room air conditioner(CRAC). In this study, ICEPAK is used to conduct a numerical analysis of a data center's cooling system. The temperature distribution and the entire room are analyzed for different volumetric flow rates. The optimized volumetric flow rate is found for each CPU power. The heat removal and temperature distribution for CPU powers of 100, 120, and 140W are found to be the best for a volumetric flow rate of 0.15m'3'/s. The numerical analysis is verified through RTI indicators, and the results appear to be the most reliable when the RTI value is 81.

    Full Text Available Background and the goal of the study: The major communicative problems, after marriage, include weakening the couples' communication, unrealistic beliefs, prejudgments and negative attitudes. The aim of this study was to determine the efficacy of Rational- Emotive Behavior Therapy,through group training, on communication beliefs of the couples who referred to counseling centers in Isfahan. Methods: The proposal of the study is a quasi-experimental research design with a pretest – posttest which includes a control group. The study samples encompass all the couples referred to counseling centers in Isfahan. In order to select a sample size, out of the applicants, through voluntary and available sampling method, 30 individuals were selected and randomly assigned to experimental and control groups. The elicitation tool used in this study was Relationship Beliefs Questionnaire. The experimental group was trained by a Rational- Emotive Behavior therapeutic approach and the control group did not receive any training at all. Then for all the participants a post-test was taken and finally after 2 months a follow-up test was conducted. In order to analyze the data, variance with repeated measures and Bonferroni correctionviausing SPSS 20 statistical software were used. Results: The results showed that the group training ofRational- Emotive Behavior therapeutic approach has impact on communicative beliefs and accordingly, there is a significant difference between the communicative beliefs of experimental and control groups(P < 0.01. Discussion: Based on the findings of this study,Rational- Emotive Behavior Therapy can be used to improve the couples' communicative beliefs.

  12. 3D Assembly Group Analysis for Cognitive Automation

    Christian Brecher

    2012-01-01

    Full Text Available A concept that allows the cognitive automation of robotic assembly processes is introduced. An assembly cell comprised of two robots was designed to verify the concept. For the purpose of validation a customer-defined part group consisting of Hubelino bricks is assembled. One of the key aspects for this process is the verification of the assembly group. Hence a software component was designed that utilizes the Microsoft Kinect to perceive both depth and color data in the assembly area. This information is used to determine the current state of the assembly group and is compared to a CAD model for validation purposes. In order to efficiently resolve erroneous situations, the results are interactively accessible to a human expert. The implications for an industrial application are demonstrated by transferring the developed concepts to an assembly scenario for switch-cabinet systems.

    We investigated the gas properties of the galaxy group UGC03957 up to $1.4R_{200} \\approx 1.4$Mpc in four azimuthal directions with the Suzaku satellite and performed a spectral analysis of five Suzaku observations with 138ks good exposure time in total as well as five Chandra snapshot observations for point source detection. We found a temperature drop of a factor of ${\\sim} 3$ from the center to the outskirts which is consistent with previous results for galaxy clusters. The metal abundance profile shows a flat behavior towards large radii which is a hint for galactic winds as the primary ICM enrichment process. The entropy profile is consistent with numerical simulations after applying a gas mass fraction correction. Previous analyses for clusters and groups often showed an entropy flattening or even a drop around ${\\sim} R_{200}$ which can be an indicator for clumping or non-equilibrium states in the outskirts. Such entropy behaviour is absent in UGC03957. The gas mass fraction is well below the cosmic me...

    Undeniably, it is human nature to prefer objects which are considered beautiful. Most consider beautiful as perfection, hence they try to create objects which are perfectly balance in shape and patterns. This creates a whole different kind of art, the kind that requires an object to be symmetrical. This leads to the study of symmetrical objects and pattern. Even mathematicians and ethnomathematicians are very interested with the essence of symmetry. One of these studies were conducted on the Malay traditional triaxial weaving culture. The patterns derived from this technique are symmetrical and this allows for further research. In this paper, the 17 symmetry types in a plane, known as the wallpaper groups, are studied and discussed. The wallpaper groups will then be applied to the triaxial patterns of food cover in Malaysia.

    CERN Document Server

    Lamothe, Vincent

    2011-01-01

    In this paper, we study the Lie point symmetry group of a system describing an ideal plastic plane flow in two dimensions in order to find analytical solutions. The infinitesimal generators that span the Lie algebra for this system are obtained. We completely classify the subalgebras of up to codimension two in conjugacy classes under the action of the symmetry group. Based on invariant forms, we use Ansatzes to compute symmetry reductions in such a way that the obtained solutions cover simultaneously many invariant and partially invariant solutions. We calculate solutions of the algebraic, trigonometric, inverse trigonometric and elliptic type. Some solutions depending on one or two arbitrary functions of one variable have also been found. In some cases, the shape of a potentially feasible extrusion die corresponding to the solution is deduced. These tools could be used to thin, curve, undulate or shape a ring in an ideal plastic material.

    In a recent sequence-analysis study it was concluded that up to 10% of the human proteome could be comprised of zinc proteins, quite varied in the functional spread. The native structures of only few of the proteins are actually established. The elucidation of rest of the sequences of not just human but even other actively investigated genomes may benefit from knowledge of the structural consensus of the zinc-binding centers of the currently known zinc proteins. Nearly four hundred X-ray and NMR structures in the database of zinc-protein structures available as of April 2007 were investigated for geometry and conformation in the zinc-binding centers; separately for the structural and catalytic proteins and individually in the zinc centers coordinated to three and four amino-acid ligands. Enhanced cysteine involvement in agreement with the observation in human proteome has been detected in contrast with previous reports. Deviations from ideal coordination geometries are detected, possible underlying reasons are investigated, and correlations of geometry and conformation in zinc-coordination centers with protein function are established, providing possible benchmarks for putative zinc-binding patterns of the burgeoning genome data.

  6. REFLEX, a social-cognitive group treatment to improve insight in schizophrenia: study protocol of a multi-center RCT

    Directory of Open Access Journals (Sweden)

    Pijnenborg GHM

    2011-10-01

    Full Text Available Abstract Background Insight is impaired in a majority of people with schizophrenia. Impaired insight is associated with poorer outcomes of the disorder. Based on existing literature, we developed a model that explains which processes may possibly play a role in impaired insight. This model was the starting point of the development of REFLEX: a brief psychosocial intervention to improve insight in schizophrenia. REFLEX is a 12-sessions group training, consisting of three modules of four sessions each. Modules in this intervention are: "coping with stigma", "you and your personal narrative", and "you in the present". Methods/Design REFLEX is currently evaluated in a multicenter randomized controlled trial. Eight mental health institutions in the Netherlands participate in this evaluation. Patients are randomly assigned to either REFLEX or an active control condition, existing of cognitive remediation exercises in a group. In a subgroup of patients, fMRI scans are made before and after training in order to assess potential haemodynamic changes associated with the effects of the training. Discussion REFLEX is one of the few interventions aiming specifically to improving insight in schizophrenia and has potential value for improving insight. Targeting insight in schizophrenia is a complex task, that comes with several methodological issues. These issues are addressed in the discussion of this paper.

The Blueboard, developed at IBM Research, is a tool for groups to use in exchanging information in a lightweight, informal collaborative way. It began as a large display surface for walk-by use in a corporate setting and has evolved in response to task demands and user needs. At NASA, the MERBoard is being designed to support surface operations for the upcoming Mars Exploration Rover Missions. The MERBoard is a tool that was inspired by the Blueboard design, extending this design to support the collaboration requirements for viewing, annotating, linking and distributing information for the science and engineering teams that will operate two rovers on the surface of Mars. The ways in which each group transformed the system reflects not only technical requirements, but also the needs of users in each setting and embedding of the system within the larger socio-technical environment. Lessons about how task requirements, information flow requirements and work practice drive the evolution of a system are illustrated.

  8. University-Community Engagement: A grid-group analysis

    Full Text Available University-community engagement involves complex issues, entangling multiple and interacting points of view, all of which operate in a wider dynamic evolving social environment. For this reason, there is often disagreement about why engagement is necessary or desirable, and whether there is one optimal method to practice it. To address this issue, I argue that university-community engagement can be examined as a form of enquiry. In this view, engagement is viewed as a system that arises through the recognition of the dissent it embodies. As such, enquiry functions to process disagreements into diverse methods of communication. Most of the disagreements utilised by universities are derived from external sources, thus university-based enquiry must necessarily involve a dialogue with a broader community or environment. In this sense, university-community engagement can be viewed most generally as a method that processes disagreements into shared understandings through enquiry. To demonstrate how university-community engagement functions from an enquiry point of view, I use Mary Douglas’ grid-group diagramming method to develop a critical typology for classifying university-community engagement. My modified grid-group diagram provides a structured typological space within which four distinct methods of university-community engagement can be identified and discussed – both in relation to their internal communicational characteristics, and in relation to each other. The university-engagement grid-group diagram is constructed by locating each of Douglas’ four quadrants within Charles Peirce’s four methods of enquiry. Peirce’s work is introduced because each of his four methods of enquiry deals specifically with how disagreements are processed and resolved. When Peirce’s methods for fixing belief are located in Douglas’ grid-group diagram, they create a sense-making framework for university-community engagement. It is argued

  9. An analysis of user engagement in student Facebook groups

    2015-08-01

    Full Text Available Analysing the engagement of students in university-based Facebook groups can shed light on the nature of their learning experience and highlight leverage points to build on student success. While post-semester surveys and demographic participation data can highlight who was involved and how they subsequently felt about the experience, these techniques do not necessarily reflect real-time engagement. One way to gain insight into in-situ student experiences is by categorising the original posts and comments into predetermined frameworks of learning. This paper offers a systematic method of coding Facebook contributions within various engagement categories: motivation, discourse, cognition and emotive responses.

    2013-06-01

    Full Text Available Utilizing observation grid and interview study methologies, this research examines the ways in which students communicate with each other while working in a team during problem solving in mathematics. The study focuses primarily on the language used for communication. Results suggest that participants make assumptions to solve mathematical problems and justify their individual opinions, and cooperate and help each other, rarely asking for their teacher’s help, while using both the ordinary, and the mathematical spoken and written language. The interview indicates that students, although not experienced in undertaking group work, are able to readily identify its benefits and positive aspects.

    We apply the higher order tensor renormalization group to lattice CP($N-1$) model in two dimensions. A tensor network representation of the CP($N-1$) model in the presence of the $\\theta$-term is derived. We confirm that the numerical results of the CP(1) model without the $\\theta$-term using this method are consistent with that of the O(3) model which is analyzed by the same method in the region $\\beta \\gg 1$ and that obtained by Monte Carlo simulation in a wider range of $\\beta$. The numerical computation including the $\\theta$-term is left for future challenges.

    2016-01-01

    A novel spectrophotometric method was developed for determination of ternary mixtures without previous separation, showing significant advantages over conventional methods. The new method is based on mean centering of double divisor ratio spectra. The mathematical explanation of the procedure is illustrated. The method was evaluated by determination of model ternary mixture and by the determination of Amlodipine (AML), Aliskiren (ALI) and Hydrochlorothiazide (HCT) in laboratory prepared mixtures and in a commercial pharmaceutical preparation. For proper presentation of the advantages and applicability of the new method, a comparative study was established between the new mean centering of double divisor ratio spectra (MCDD) and two similar methods used for analysis of ternary mixtures, namely mean centering (MC) and double divisor of ratio spectra-derivative spectrophotometry (DDRS-DS). The method was also compared with a reported one for analysis of the pharmaceutical preparation. The method was validated according to the ICH guidelines and accuracy, precision, repeatability and robustness were found to be within the acceptable limits.

    2016-03-01

    Anion ordering in the structure of cubic perovskite has been investigated by the group-theoretical method. The possibility of the existence of 261 ordered low-symmetry structures, each with a unique space-group symmetry, is established. These results include five binary and 14 ternary anion superstructures. The 261 idealized anion-ordered perovskite structures are considered as aristotypes, giving rise to different derivatives. The structures of these derivatives are formed by tilting of BO6 octahedra, distortions caused by the cooperative Jahn-Teller effect and other physical effects. Some derivatives of aristotypes exist as real substances, and some as virtual ones. A classification of aristotypes of anion superstructures in perovskite is proposed: the AX class (the simultaneous ordering of A cations and anions in cubic perovskite structure), the BX class (the simultaneous ordering of B cations and anions) and the X class (the ordering of anions only in cubic perovskite structure). In most perovskites anion ordering is accompanied by cation ordering. Therefore, the main classes of anion order in perovskites are the AX and BX classes. The calculated structures of some anion superstructures are reported. Comparison of predictions and experimentally investigated anion superstructures shows coherency of theoretical and experimental results.

    2014-01-01

    Background: The concept of family- centered care in neonatal intensive care unit has changed drastically in protracted years and has been used in various contexts differently. Since we require clarity in our understanding, we aimed to analyze this concept. Methods: This study was done on the basis of developmental approach of Rodgers’s concept analysis. We reviewed the existing literature in Science direct, PubMed, Google Scholar, Scopus, and Iran Medex databases from 1980 to 2012. The keywords were family-centered care, family-oriented care, and neonatal intensive care unit. After all, 59 out of 244 English and Persian articles and books (more than 20%) were selected. Results: The attributes of family-centered care in neonatal intensive care unit were recognized as care taking of family (assessment of family and its needs, providing family needs), equal family participation (participation in care planning, decision making, and providing care from routine to special ones), collaboration (inter-professional collaboration with family, family involvement in regulating and implementing care plans), regarding family’s respect and dignity (importance of families’ differences, recognizing families’ tendencies), and knowledge transformation (information sharing between healthcare workers and family, complete information sharing according to family learning style). Besides, the recognized antecedents were professional and management-organizational factors. Finally, the consequences included benefits related to neonate, family, and organization. Conclusion: The findings revealed that family centered-care was a comprehensive and holistic caring approach in neonatal intensive care. Therefore, it is highly recommended to change the current care approach and philosophy and provide facilities for conducting family-centered care in neonatal intensive care unit.  PMID:25349870

  16. Behavioural activation for depression; an update of meta-analysis of effectiveness and sub group analysis.

    Directory of Open Access Journals (Sweden)

    David Ekers

    Full Text Available BACKGROUND: Depression is a common, disabling condition for which psychological treatments are recommended. Behavioural activation has attracted increased interest in recent years. It has been over 5 years since our meta-analyses summarised the evidence supporting and this systematic review updates those findings and examines moderators of treatment effect. METHOD: Randomised trials of behavioural activation for depression versus controls or anti-depressant medication were identified using electronic database searches, previous reviews and reference lists. Data on symptom level and study level moderators were extracted and analysed using meta-analysis, sub-group analysis and meta-regression respectively. RESULTS: Twenty six randomised controlled trials including 1524 subjects were included in this meta-analysis. A random effects meta-analysis of symptom level post treatment showed behavioural activation to be superior to controls (SMD -0.74 CI -0.91 to -0.56, k = 25, N = 1088 and medication (SMD -0.42 CI -0.83 to-0.00, k = 4, N = 283. Study quality was low in the majority of studies and follow- up time periods short. There was no indication of publication bias and subgroup analysis showed limited association between moderators and effect size. CONCLUSIONS: The results in this meta-analysis support and strengthen the evidence base indicating Behavioural Activation is an effective treatment for depression. Further high quality research with longer term follow-up is needed to strengthen the evidence base.

    Sadel, Christian

    2008-01-01

    A random Lie group action on a compact manifold generates a discrete time Markov process. The main object of this paper is the evaluation of associated Birkhoff sums in a regime of weak, but sufficiently effective coupling of the randomness. This effectiveness is expressed in terms of random Lie algebra elements and replaces the transience or Furstenberg's irreducibility hypothesis in related problems. The Birkhoff sum of any given smooth function then turns out to be equal to its integral w.r.t. a unique smooth measure on the manifold up to errors of the order of the coupling constant. Applications to the theory of products of random matrices and a model of a disordered quantum wire are presented.

    Tanimoto, Keishi; Sugimoto, Yasuaki; Miyamoto, Shinya; Nada, Hideki; Hosoi, Yoshihiko

    Recently, it is critical to manage deteriorating sewerage and road facilities efficiently and strategically. Since the sewerage pipes are mostly installed under road pavement, the works for the replacement of the sewerage pipes are partially common to the works for the road. This means that the replacement cost can be saved by coordinating the timing of the replacements by sewerage pipe and road pavement. The purpose of the study is to develop the model based on Markov decision process to derive the optimal group maintenance policy so as to minimize lifecycle cost. Then the model is applied to case study area and demonstrated to estimate the lifecycle cost using statistical data such as pipe replacement cost, road pavement rehabilitation cost, and state of deterioration of pipes and road pavement.

    We have developed tools to explore social networks that share information in medical forums to better understand the unmet informational needs of patients and family members facing cancer treatments. We define metrics that demonstrate members discussing interleukin-2 receive a stronger response from the melanoma discussion group than a typical topic. The interleukin-2 network has a different topology than the melanoma network, has a higher density, and its members are more likely to have a higher intimacy level with another member and a lower inquisitiveness level than a typical melanoma user. Members are more likely to join the interleukin-2 network to answer a question than in the melanoma network (probability =.2 ±.05 p-value=.001). Within the melanoma network 20% of the questions posed to the community do not get an answer. In the interleukin-2 network, 1.3% of the questions (one question) do not get a response. PMID:21347134

    2015-03-01

    The past decade has seen dramatic shifts in the way that scientific research is conducted as networks, consortia, and large research centers are funded as transdisciplinary, team-based enterprises to tackle complex scientific questions. Key investigators (N = 167) involved in ten health disparities research centers completed a baseline social network and collaboration readiness survey. Collaborative ties existed primarily between investigators from the same center, with just 7 % of ties occurring across different centers. Grants and work groups were the most common types of ties between investigators, with shared presentations the most common tie across different centers. Transdisciplinary research orientation was associated with network position and reciprocity. Center directors/leaders were significantly more likely to form ties with investigators in other roles, such as statisticians and trainees. Understanding research collaboration networks can help to more effectively design and manage future team-based research, as well as pinpoint potential issues and continuous evaluation of existing efforts.

  1. A statistical analysis of the Two Dimensional XMM-Newton Group Survey: The impact of feedback on group properties

    2009-01-01

    (abridged) We present a statistical analysis of 28 nearby galaxy groups from the Two-Dimensional XMM-Newton Group Survey (2dXGS). We focus on entropy and the role of feedback, dividing the sample into cool core (CC) and non cool core (NCC) systems, the first time the latter have been studied in detail in the group regime. The coolest groups have steeper entropy profiles than the warmest systems, and NCC groups have higher central entropy and exhibit more scatter than their CC counterparts. We compare the entropy distribution of the gas in each system to the expected theoretical distribution ignoring non-gravitational processes. In all cases, the observed maximum entropy far exceeds that expected theoretically, and simple models for modifications of the theoretical entropy distribution perform poorly. Applying initial pre-heating, followed by radiative cooling, generally fails to match the low entropy behaviour, and only performs well when the difference between the maximum entropy of the observed and theoreti...

  2. Likelihood analysis of the Local Group acceleration revisited

    Ciecielag, P

    2004-01-01

    We reexamine likelihood analyzes of the Local Group (LG) acceleration, paying particular attention to nonlinear effects. Under the approximation that the joint distribution of the LG acceleration and velocity is Gaussian, two quantities describing nonlinear effects enter these analyzes. The first one is the coherence function, i.e. the cross-correlation coefficient of the Fourier modes of gravity and velocity fields. The second one is the ratio of velocity power spectrum to gravity power spectrum. To date, in all analyzes of the LG acceleration the second quantity was not accounted for. Extending our previous work, we study both the coherence function and the ratio of the power spectra. With the aid of numerical simulations we obtain expressions for the two as functions of wavevector and \\sigma_8. Adopting WMAP's best determination of \\sigma_8, we estimate the most likely value of the parameter \\beta and its errors. As the observed values of the LG velocity and gravity, we adopt respectively a CMB-based estim...

  3. Classical and Quantum Burgers Fluids: A Challenge for Group Analysis

    Philip Broadbridge

    2015-10-01

    Full Text Available The most general second order irrotational vector field evolution equation is constructed, that can be transformed to a single equation for the Cole–Hopf potential. The exact solution to the radial Burgers equation, with constant mass influx through a spherical supply surface, is constructed. The complex linear Schrödinger equation is equivalent to an integrable system of two coupled real vector equations of Burgers type. The first velocity field is the particle current divided by particle probability density. The second vector field gives a complex valued correction to the velocity that results in the correct quantum mechanical correction to the kinetic energy density of the Madelung fluid. It is proposed how to use symmetry analysis to systematically search for other constrained potential systems that generate a closed system of vector component evolution equations with constraints other than irrotationality.

    Full Text Available The quantitative analysis of pooled data from related fMRI experiments has the potential to significantly accelerate progress in brain mapping. Such data-pooling can be achieved through meta-analysis (the pooled analysis of published results, mega-analysis (the pooled analysis of raw data or multi-site studies which can be seen as designed mega-analyses. Current limitations in function-location brain mapping and how data-pooling can be used to remediate them are reviewed, with particular attention to power aggregation and mitigation of false positive results. Some recently developed analysis tools for meta- and mega-analysis are also presented, and recommendations for the conduct of valid fMRI data pooling are formulated.

    2015-01-01

    A large test article was recently designed, analyzed, fabricated, and successfully tested up to the representative design ultimate loads to demonstrate that stiffened composite panels with through-the-thickness reinforcement are a viable option for the next generation large transport category aircraft, including non-conventional configurations such as the hybrid wing body. This paper focuses on finite element analysis and test data correlation of the hybrid wing body center section test article under mechanical, pressure and combined load conditions. Good agreement between predictive nonlinear finite element analysis and test data is found. Results indicate that a geometrically nonlinear analysis is needed to accurately capture the behavior of the non-circular pressurized and highly-stressed structure when the design approach permits local buckling.

    Developing a sense of community among students is one of the three pillars of an overall reform effort to increase participation in physics, and the sciences more broadly, at Florida International University. The emergence of a research and learning community, embedded within a course reform effort, has contributed to increased recruitment and retention of physics majors. Finn and Rock [1] link the academic and social integration of students to increased rates of retention. We utilize social network analysis to quantify interactions in Florida International University's Physics Learning Center (PLC) that support the development of academic and social integration,. The tools of social network analysis allow us to visualize and quantify student interactions, and characterize the roles of students within a social network. After providing a brief introduction to social network analysis, we use sequential multiple regression modeling to evaluate factors which contribute to participation in the learning community. ...

    2002-08-01

    Cost studies, productivity, efficiency, and quality of care measures, the links between resources and patient outcomes, are fundamental issues for hospital management today. This paper describes the implementation of a model for process analysis and activity-based costing (ABC)/management at a Heart Center in Sweden as a tool for administrative cost information, strategic decision-making, quality improvement, and cost reduction. A commercial software package (QPR) containing two interrelated parts, "ProcessGuide and CostControl," was used. All processes at the Heart Center were mapped and graphically outlined. Processes and activities such as health care procedures, research, and education were identified together with their causal relationship to costs and products/services. The construction of the ABC model in CostControl was time-consuming. However, after the ABC/management system was created, it opened the way for new possibilities including process and activity analysis, simulation, and price calculations. Cost analysis showed large variations in the cost obtained for individual patients undergoing coronary artery bypass grafting (CABG) surgery. We conclude that a process-based costing system is applicable and has the potential to be useful in hospital management.

    2011-01-01

    The topic of the paper is a preliminary analysis of 1743 data calculated for 249 High-z SCP Union supernovae, according to the expansion center model. The analysis of the ECM data set in Hubble units begins with 13 listed normal points corresponding to 13 z-bin samples at as many Hubble depths. Here the novel finding is a resulting clear drop in the average scattering of the SNe Ia absolute magnitudes M with the ECM Hubble depth D, after using the average trend computed in paper IX and here reconfirmed. Other correlations of the M scattering with the position in the sky are proposed as pointers for future investigations. Consequently, 13 ECM dipole tests on the 13 z-bin samples were carried out both with unweighed and weighed fittings. A further check was made through another ECM dipole test on the same 13 z bins, with Hubble depths D obtained by assuming M= according to paper IX and X. In conclusion the analysis of 249 SCP SNe confirms once again the expansion center model at any Hubble depth, including a s...

    Data testing of ENDF/B-VI.2 was performed and ACE-format continuous point-wise cross section library from ENDF/B-VI.2 for MCNP was validated through CSEWG benchmark and power plant mockup experiments. The calculated k-effective of ORNL-1, -2, -3, -4 and -10 with ENDF/B-VI are low by about 0.5% but those of L-7, -8, -9, -10 and -11 show good agreement with experiments. Overall results for uranium core with ENDF/B-VI is low in critically than with ENDF/B-V. The calculated results with ENDF/B-VI for PNL-6 {approx} 12 of plutonium core and PNL-30 {approx} 35 of mixed oxide core show good agreement with the experiments. The results of critically calculation for fast core benchmark do not show large difference between ENDF/B-VI and -V. But the calculated results of reaction rate ratio with ENDF/B-VI are improved, compared with ENDF/B-V. The calculated power distribution for VENUS PWR mockup core and typical BWR core of GE with both of ENDF/B-VI and -V agree well with measured values. From the above results, newly generated MCNP library from ENDF/B-VI is useful for nuclear and shielding design and analysis. 5 figs, 13 tabs, 11 refs. (Author).

    -subject studies. Independent vector analysis (IVA) is a promising alternative approach to perform group fMRI analysis, which has been shown to better capture components with high inter-subject variability. The most widely applied IVA method is based on the multivariate Laplace distribution (IVA-GL), which assumes...... independence within subject components coupled across subjects only through shared scaling. In this study, we propose a more natural formulation of IVA based on a Normal-Inverse-Gamma distribution (IVA-NIG), in which the components can be directly interpreted as realizations of a common mean component...... with individual subject variability. We evaluate the performance of IVA-NIG compared to IVA-GL and similar decomposition methods, through the application of two types of simulated data and on real task fMRI data. The results show that IVA-NIG offers superior detection of components in simulated fMRI data. On real...

    2016-12-01

    We present results of the DORIS data processing for the ITRF2014 carried out in the Institute of Astronomy, Russian Academy of Sciences (short INA) for the time period 1993.0-2015.0. The evaluated SINEX free-network (inawd08) weekly solutions for station positions and polar motion have been submitted to the IDS Combination Center. We applied the upgraded models of the gravity field, troposphere, and used corrected data for SPOT-5 satellite which permitted us to improve the result precision for Helmert transformation parameters and EOP. The agreement with the IERS C04 solution turns out better than 0.1 mas with a dispersion of 1 mas. The evaluated amplitudes of annual geocenter variations derived from inawd08 weekly solutions are 3.4 ± 0.5 mm, 4.4 ± 0.5 mm, and 3.3 ± 1.0 mm for X, Y, and Z components, respectively. The recovered amplitudes and phases are in a good agreement with the geophysical models. The results of two single satellite campaigns related to the scale increase in 2012 and 1994 for IDS combination are studied. Unlike other Analysis Centers, we did not apply a phase center law for ground antennas. It was shown that the correction for the phase center variation (PCV) of ground DORIS antennas results in the shift of the mean scale factor by 1.24 ppb (i.e., ∼8 mm) with respect to the case without correction. The PCV model and the satellites HY-2A and SARAL are included into the INA latest solutions (inawd10) after the submission for the ITRF2014. The future work is discussed.

  14. Control of oscillation periods and phase durations in half-center central pattern generators: a comparative mechanistic analysis.

    Daun, Silvia; Rubin, Jonathan E; Rybak, Ilya A

    2009-08-01

    Central pattern generators (CPGs) consisting of interacting groups of neurons drive a variety of repetitive, rhythmic behaviors in invertebrates and vertebrates, such as arise in locomotion, respiration, mastication, scratching, and so on. These CPGs are able to generate rhythmic activity in the absence of afferent feedback or rhythmic inputs. However, functionally relevant CPGs must adaptively respond to changing demands, manifested as changes in oscillation period or in relative phase durations in response to variations in non-patterned inputs or drives. Although many half-center CPG models, composed of symmetric units linked by reciprocal inhibition yet varying in their intrinsic cellular properties, have been proposed, the precise oscillatory mechanisms operating in most biological CPGs remain unknown. Using numerical simulations and phase-plane analysis, we comparatively investigated how the intrinsic cellular features incorporated in different CPG models, such as subthreshold activation based on a slowly inactivating persistent sodium current, adaptation based on slowly activating calcium-dependent potassium current, or post-inhibitory rebound excitation, can contribute to the control of oscillation period and phase durations in response to changes in excitatory external drive to one or both half-centers. Our analysis shows that both the sensitivity of oscillation period to alterations of excitatory drive and the degree to which the duration of each phase can be separately controlled depend strongly on the intrinsic cellular mechanisms involved in rhythm generation and phase transitions. In particular, the CPG formed from units incorporating a slowly inactivating persistent sodium current shows the greatest range of oscillation periods and the greatest degree of independence in phase duration control by asymmetric inputs. These results are explained based on geometric analysis of the phase plane structures corresponding to the dynamics for each CPG type

    The reaction center (RC) complex of the green sulfur bacterium Chlorobaculum tepidum is composed of the Fenna-Matthews-Olson antenna protein (FMO) and the reaction center core (RCC) complex. The RCC complex has four subunits: PscA, PscB, PscC, and PscD. We studied the FMO/RCC complex by chemically cross-linking the purified sample followed by biochemical and spectroscopic analysis. Blue-native gels showed that there were two types of FMO/RCC complexes, which are consistent with complexes with one copy of FMO per RCC and two copies of FMO per RCC. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis analysis of the samples after cross-linking showed that all five subunits of the RC can be linked by three different cross-linkers: bissulfosuccinimidyl suberate, disuccinimidyl suberate, and 3,3-dithiobis-sulfosuccinimidyl propionate. The interaction sites of the cross-linked complex were also studied using liquid chromatography coupled to tandem mass spectrometry. The results indicated that FMO, PscB, PscD, and part of PscA are exposed on the cytoplasmic side of the membrane. PscD helps stabilize FMO to the reaction center and may facilitate transfer of the electron from the RC to ferredoxin. The soluble domain of the heme-containing cytochrome subunit PscC and part of the core subunit PscA are located on the periplasmic side of the membrane. There is a close relationship between the periplasmic portions of PscA and PscC, which is needed for the efficient transfer of the electron between PscC and P840.

    2007-07-01

    Full Text Available Introduction: Many organizations, especially service oriented ones, relative to their goals and mission, have a special view towards quality phenomena and its management. Methods: This paper analyzes medical service quality in one case; The internal section of Shaheed Rahnemoon Hospital Based on the basis of gap analysis model and Servqual technique. A questionnaire was designed and applied to measure expectations and perceptions of patients and personnel of the hospital. Results: On application of non-parametric statistical tests, we propose certain recommendations. These tests drive on five conceptual dimensions of service quality including intangibility, responsiveness, reliability, assurance and empathy. Results show that patients in this section were satisfied from the service provider’s responsiveness, but there are significant differences between expectations and perceptions in other dimensions. Conclusion: The service quality analysis models are useful for managers of medical centers to distinguish gaps between the two sides of service representation; patients and medical centers personnel. Ultimately, they can reinforce strengths and control weaknesses.

    Multidisciplinary analysis and design is inherently a team activity due to the variety of required expertise and knowledge. As a team activity, multidisciplinary research cannot escape the issues that affect all teams. The level of technical diversity required to perform multidisciplinary analysis and design makes the teaming aspects even more important. A study was conducted at the NASA Langley Research Center to develop a model of multidiscipline teams that can be used to help understand their dynamics and identify key factors that influence their effectiveness. The study sought to apply the elements of systems thinking to better understand the factors, both generic and Langley-specific, that influence the effectiveness of multidiscipline teams. The model of multidiscipline research teams developed during this study has been valuable in identifying means to enhance team effectiveness, recognize and avoid problem behaviors, and provide guidance for forming and coordinating multidiscipline teams.

  3. Using multiple group modeling to test moderators in meta-analysis.

    Science.gov (United States)

    Schoemann, Alexander M

    2016-12-01

    Meta-analysis is a popular and flexible analysis that can be fit in many modeling frameworks. Two methods of fitting meta-analyses that are growing in popularity are structural equation modeling (SEM) and multilevel modeling (MLM). By using SEM or MLM to fit a meta-analysis researchers have access to powerful techniques associated with SEM and MLM. This paper details how to use one such technique, multiple group analysis, to test categorical moderators in meta-analysis. In a multiple group meta-analysis a model is fit to each level of the moderator simultaneously. By constraining parameters across groups any model parameter can be tested for equality. Using multiple groups to test for moderators is especially relevant in random-effects meta-analysis where both the mean and the between studies variance of the effect size may be compared across groups. A simulation study and the analysis of a real data set are used to illustrate multiple group modeling with both SEM and MLM. Issues related to multiple group meta-analysis and future directions for research are discussed. Copyright © 2016 John Wiley & Sons, Ltd.

CONCLUSIONS In this single academic medical center cost analysis, DBS performed asleep was associated with a lower cost variation relative to the awake procedure. Furthermore, costs compared favorably to UHC-affiliated hospitals. While asleep DBS is not yet standard practice, this center exclusively performs asleep DBS at a lower cost than comparable institutions.

    Background Orthotopic liver retransplantation (re-OLT) is the only effective therapy for irreversible failure of a liver graft. Early and late graft failure gives way to two different clinical conditions that should be discussed separately. This study was designed to compare early and late re-OLT for patients with poor graft function after primary transplantation at our center and sum up our clinical experience in re-OLT.Methods The clinical data of 31 re-OLTs at our center from January 2004 to February 2007 were analyzed retrospectively, consisting of the first group with 14 cases of early re-OLT and the second group with 17 cases of late re-OLT.Results Biliary tract complications were the main indications for early re-OLT (57.1%) and late re-OLT (52.9%). Other common indications were vascular complications in early re-OLT and recurrence of primary diseases in late re-OLT. No significant differences were found between the groups with regard to the volume of bleeding during operation, cold ischemia time, operative duration, and perioperative mortality; except for the model of end-stage liver disease (MELD) score. Outcome was fatal for 7 patients in early re-OLT and 9 patients in late re-OLT. Two deaths were due to multiple organ failure with 3 deaths due to severe sepsis-related disease in early re-OLT, and 4 deaths were due to severe sepsis-related disease with 3 deaths due to recurrence of hepatocellular carcinoma (HCC) in late re-OLT. One and 2-year actuarial survival rates after re-OLT were 55.2% and 36.9%, respectively, for patients in early re-OLT, and 65.1% and 52% respectively, for patients in late re-OLT. No significant differences were found regarding survival rates between the two groups.Conclusions Similar clinical results can be achieved in early and late re-OLT. Proper indications and optimal operation timing, adequate preoperative preparation, experienced surgical procedures, and effective perioperative anti-infection strategy contribute to the

    2015-01-01

    In order to obtain a simple way for the force analysis of metamorphic mechanisms, the systematic method to unify the force analysis approach of metamorphic mechanisms as that of conventional planar mechanisms is proposed. A force analysis method of metamorphic mechanisms is developed by transforming the augmented Assur groups into Assur groups, so that the force analysis problem of metamorphic mechanisms is converted into the force analysis problems of conventional planar mechanisms. The constraint force change rules and values of metamorphic joints are obtained by the proposed method, and the constraint force analysis equations of revolute metamorphic joints in augmented Assur group RRRR and prismatic metamorphic joints in augmented Assur group RRPR are deduced. The constraint force analysis is illustrated by the constrained spring force design of paper folding metamorphic mechanism, and its metamorphic working process is controlled by the spring force and geometric constraints of metamorphic joints. The results of spring force show that developped design method and approach are feasible and practical. By transforming augmented Assur groups into Assur groups, a new method for the constraint force analysis of metamorphic joints is proposed firstly to provide the basis for dynamic analysis of metamorphic mechanism.

    Full Text Available Sensitivity assessment of availability for data center networks (DCNs is of paramount importance in design and management of cloud computing based businesses. Previous work has presented a performance modeling and analysis of a fat-tree based DCN using queuing theory. In this paper, we present a comprehensive availability modeling and sensitivity analysis of a DCell-based DCN with server virtualization for business continuity using stochastic reward nets (SRN. We use SRN in modeling to capture complex behaviors and dependencies of the system in detail. The models take into account (i two DCell configurations, respectively, composed of two and three physical hosts in a DCell0 unit, (ii failure modes and corresponding recovery behaviors of hosts, switches, and VMs, and VM live migration mechanism within and between DCell0s, and (iii dependencies between subsystems (e.g., between a host and VMs and between switches and VMs in the same DCell0. The constructed SRN models are analyzed in detail with regard to various metrics of interest to investigate system’s characteristics. A comprehensive sensitivity analysis of system availability is carried out in consideration of the major impacting parameters in order to observe the system’s complicated behaviors and find the bottlenecks of system availability. The analysis results show the availability improvement, capability of fault tolerance, and business continuity of the DCNs complying with DCell network topology. This study provides a basis of designing and management of DCNs for business continuity.

  13. Strategy for Self-Centered Development from the Perspective of an Historical Analysis of Development

    Directory of Open Access Journals (Sweden)

    Alfredo Pérez Sánchez

    1998-04-01

    Full Text Available After acknowledging the three phases of historical analysis of development, and especially considering the research work done in the last twenty-five years by the Germans Dieter Sengcheus and Ulrich Mezel, the author presents the principle elements of a self-centered development strategy which highlights the following perspectives:dissociation, economic restructuring, and the new forms of an international division of labor among Third World economies.This document calls into question the underlying operation of the conventional theory of development and its current policy, which call for the increasing integration of the Third World in the world market as a means of going beyond development as it is commonly understood. Though being an integral element in the theory of self-centereddevelopment, temporary dissociation from the world market is proposed. The justification for the strategy of dissociation, excepting the recourse to some historical and paradigmatic reflections sketched by Friedrich List, has kept itself, of necessity, to the global and abstract level. This position is nothing, however, but a most direct analytical result deduced fromthe principle theoretical beginnings and the empirical observations of both the Theory of Dependence and Peripheral Capitalism. Although the review vents its criticism on (and mainly questions the practicality of the aforesaid conception, a more penetratingunderstanding of what the wager for such a strategy entails is found. Thus, the notion of self-centered development influences and gives impulse to a most extensive ideologicallymarked debate about the alternative conceptions of development.

    1996-02-01

    Commercial energy use costs businesses around $70 billion annually. Many of these businesses are small and medium sized organizations that do not have the resources to help themselves, or to pay for professional engineering services to help reduce their energy costs and improve their economic competitiveness. Energy cost reduction actions with payback times of around two years could save the commercial sector 15--20%, or $10--$15 billion per year. This project was initially intended to evaluate the feasibility of performing commercial energy audits as an adjunct to the industrial audit program run by the US Department of Energy Industrial Office. This program is housed in 30 universities throughout the United States. Formerly known as Energy Analysis and Diagnostic Centers (EADC`s), the university programs are now called Industrial Assessment Centers (IAC`s) to reflect their expansion from energy use analyses to include waste and productivity analyses. The success of the EADC/IAC program in helping the manufacturing sector provides an excellent model for a similar program in the commercial buildings sector. This project has investigated using the EADC/IAC approach to performing energy audits for the commercial sector, and has determined that such an approach is feasible and cost effective.

  16. Incipient Social Groups: An Analysis via In-Vivo Behavioral Tracking.

    Directory of Open Access Journals (Sweden)

    Jamin Halberstadt

    Full Text Available Social psychology is fundamentally the study of individuals in groups, yet there remain basic unanswered questions about group formation, structure, and change. We argue that the problem is methodological. Until recently, there was no way to track who was interacting with whom with anything approximating valid resolution and scale. In the current study we describe a new method that applies recent advances in image-based tracking to study incipient group formation and evolution with experimental precision and control. In this method, which we term "in vivo behavioral tracking," we track individuals' movements with a high definition video camera mounted atop a large field laboratory. We report results of an initial study that quantifies the composition, structure, and size of the incipient groups. We also apply in-vivo spatial tracking to study participants' tendency to cooperate as a function of their embeddedness in those crowds. We find that participants form groups of seven on average, are more likely to approach others of similar attractiveness and (to a lesser extent gender, and that participants' gender and attractiveness are both associated with their proximity to the spatial center of groups (such that women and attractive individuals are more likely than men and unattractive individuals to end up in the center of their groups. Furthermore, participants' proximity to others early in the study predicted the effort they exerted in a subsequent cooperative task, suggesting that submergence in a crowd may predict social loafing. We conclude that in vivo behavioral tracking is a uniquely powerful new tool for answering longstanding, fundamental questions about group dynamics.

    2017-02-01

    Full Text Available This paper presents an analysis of a parallelogram mechanism commonly used to provide a kinematic remote center of motion in surgical telemanipulators. Selected types of parallel manipulator designs, encountered in commercial and laboratory-made designs described in the medical robotics literature, will serve as the research material. Among other things, computer simulations in the ANSYS 13.0 CAD/CAE software environment, employing the finite element method, will be used. The kinematics of the solution of manipulator with the parallelogram mechanism will be determined in order to provide a more complete description. These results will form the basis for the decision regarding the possibility of applying a parallelogram mechanism in an original prototype of a telemanipulator arm.

    Within the frame of the International DORIS Service, the CNES/CLS Analysis Center, previously known as LCA and renamed GRG, contributes to the geodetic and geophysical research activity through DORIS data analysis. The main work carried out in the past two years concerns the processing of the measurements collected by the DORIS-equipped satellites over 22 years, in order to provide a homogeneous series of station coordinates and Earth pole parameters for the IDS contribution to the ITRF2014. First, we brought several upgrades to the processing and the modeling. Some of them are corrective actions to issues raised during or shortly after the production of our contribution to the ITRF2008 (ground station frequency offsets, attitude laws and macromodels). Recent models have been assessed with the aim to update our analysis configuration. Among others, we adopted the time variable gravity (TVG) model EIGEN-6S2 and applied tropospheric gradients. Then we processed almost all the DORIS data collected between January 1993 and December 2014. The series of weekly SINEX solutions derived from this processing is labeled grgwd40. This new series performs better than the series produced for ITRF2008. Especially, the results discussed in this paper show a decrease of 2% of the DORIS orbit residuals as well as a strong reduction of the annual terms of the TRF scale and Tz translation which can be explained by the application of the TVG model.

    Hepatocellular carcinoma (HCC) can be diagnosed based on characteristic findings of arterial-phase enhancement and portal/delayed 'washout' in cirrhotic patients. Several countries and major academic societies have proposed varying specific diagnostic criteria for HCC, largely reflecting the variable HCC prevalence in different regions and ethnic groups, as well as different practice patterns. In 2014, a new version of Korean practice guidelines for management of HCC was released by the Korean Liver Cancer Study Group (KLCSG) and the National Cancer Center (NCC). According to the KLCSG-NCC Korea practice guidelines, if the typical hallmark of HCC (i.e., hypervascularity in the arterial phase with washout in the portal or 3 min-delayed phases) is identified in a nodule ≥ 1 cm in diameter on either dynamic CT, dynamic MRI, or MRI using hepatocyte-specific contrast agent in high-risk groups, a diagnosis of HCC is established. In addition, the KLCSG-NCC Korea practice guidelines provide criteria to diagnose HCC for subcentimeter hepatic nodules according to imaging findings and tumor marker, which has not been addressed in other guidelines such as Association for the Study of Liver Diseases and European Association for the Study of the Liver. In this review, we briefly review the new HCC diagnostic criteria endorsed by the 2014 KLCSG-NCC Korea practice guidelines, in comparison with other recent guidelines; we furthermore address several remaining issues in noninvasive diagnosis of HCC, including prerequisite of sonographic demonstration of nodules, discrepancy between transitional phase and delayed phase, and implementation of ancillary features for HCC diagnosis.

    Captive breeding programs are an important tool for the conservation of endangered species. These programs are commonly managed using pedigrees containing information about the history of each individual's family, such as breeding pairs and parentage. However, there are some species that are kept in groups where it is hard to distinguish between particular individuals within the group, making it very difficult to record any information at an individual level. Currently, software and methods commonly used for registering and analyzing pedigrees to help manage populations at an individual level are not adequate for managing these group-living species. Therefore, there is a need to further develop these tools and methodologies for pedigree analysis to better manage group-living species. PMx is a program used for the management of ex situ populations in zoos and aquariums. We adapted the pedigree analysis method implemented in PMx to analyze pedigrees (records of descendant lineages) of group-living species. In addition, we developed a group pedigree data entry sheet and group2PMx, a converter program that enables group datasets to be imported into PMx. We show how pedigree analysis of a group-living species can be used for population management using the studbook of the endangered Texas blind cave salamander Eurycea rathbuni. Such analyses of the pedigree of groups can improve the management of group-living species in ex situ breeding programs. Firstly, it enables better management decisions based on more accurate genetic measures between groups, allowing for greater control of inbreeding. Secondly, it can improve the conditions in which group-living species are held by adapting husbandry practices to better reflect conditions of these species living in the wild. The use of the spreadsheet and group2PMx extends the application of PMx, allowing conservation managers and other institutions outside the zoo and aquarium community to easily import and analyze their

    2009-01-01

    In this work we will investigate Lagrangians of the standard model extended by three right-handed neutrinos, and the consequences of invariance under finite groups G for lepton masses and mixing matrices are studied. The main part of this thesis is the systematic analysis of finite subgroups of SU(3). The analysis of these groups may act as a toolkit for future model building.

    Full Text Available Background: Participatory approaches to qualitative research practice constantly change in response to evolving research environments. Researchers are increasingly encouraged to undertake secondary analysis of qualitative data, despite epistemological and ethical challenges. Interpretive focus groups can be described as a more participative method for groups to analyse qualitative data. Objective: To facilitate interpretive focus groups with women in Papua New Guinea to extend analysis of existing qualitative data and co-create new primary data. The purpose of this was to inform a transformational grounded theory and subsequent health promoting action. Design: A two-step approach was used in a grounded theory study about how women experience male circumcision in Papua New Guinea. Participants analysed portions or ‘chunks’ of existing qualitative data in story circles and built upon this analysis by using the visual research method of storyboarding. Results: New understandings of the data were evoked when women in interpretive focus groups analysed the data ‘chunks’. Interpretive focus groups encouraged women to share their personal experiences about male circumcision. The visual method of storyboarding enabled women to draw pictures to represent their experiences. This provided an additional focus for whole-of-group discussions about the research topic. Conclusions: Interpretive focus groups offer opportunity to enhance trustworthiness of findings when researchers undertake secondary analysis of qualitative data. The co-analysis of existing data and co-generation of new data between research participants and researchers informed an emergent transformational grounded theory and subsequent health promoting action.

    As part of the Undergraduate ALFALFA Team, we are conducting a survey of the gas and star-formation properties of galaxies in 36 groups and clusters in the local universe. The galaxies in our sample span a large range of galactic environments, from the centers of galaxy groups and clusters to the surrounding infall regions. One goal of the project is to map the spatial distribution of star-formation; the relative extent of the star-forming and stellar disks provides important information about the internal and external processes that deplete gas and thus drive galaxy evolution. We obtained wide-field H-alpha observations with the WIYN 0.9m telescope at Kitt Peak National Observatory for galaxies in the vicinity of the MKW11 and NRGb004 galaxy groups and the Abell 1367 cluster. We present a preliminary analysis of the relative size of the star-forming and stellar disks as a function of galaxy morphology and local galaxy density, and we calculate gas depletion times using star-formation rates and HI gas mass. We will combine these results with those from other UAT members to determine if and how environmentally-driven gas depletion varies with the mass and X-ray properties of the host group or cluster. This work has supported by NSF grants AST-0847430, AST-1211005 and AST-1637339.

    Full Text Available Background: With Caesarean sections on the rise WHO proposes that health care facilities use the Robson's 10 group classification system to audit their C-sections rates. This classification would help understand the internal structure of the CS rates at individual health facilities identify key population groups, indications in each group and formulate strategies to reduce these rates. Methods: This was a cross sectional study for a period of 24 months at a tertiary care hospital in a tribal area of Kerala South India. Women who delivered during this period were included and classified into 10 Robson's classes and percentages were calculated for the overall rate, the representation of groups, contribution of groups and Caesarean percentage in each group. Results: Highest contribution was by Group 5 and Group 2. Together these two groups contributed to 38% of the total Caesareans. Followed by Group 8 and 10. All four added contributed to 63% of the section rate The least contribution was by Group 3. Groups 6, 7 and 9 by themselves did not contribute much but within their groups had a 100% C-Section rate. Conclusions: The contribution of the various Robson's Group to the absolute C-Section rates needs to be looked into. Reducing primary section rates, adequate counselling and encouraging for VBAC, changing the norms for dystocia and non-reassuring fetal status, training and encouraging obstetricians to perform versions when not contraindicated could reduce the contribution of Robson's groups towards the absolute C-Section rates.

    The catastrophic destruction of the World Trade Center (WTC) on 11 September 2001 caused the release of high levels of airborne pollutants into the local environment. To assess the toxicity of fine particulate matter [particulate matter with a mass median aerodynamic diameter fraction was isolated on filters. Here we report the chemical and physical properties of PM2.5 derived from these samples and compare them with PM2.5 fractions of three reference materials that range in toxicity from relatively inert to acutely toxic (Mt. St. Helens PM; Washington, DC, ambient air PM; and residual oil fly ash). X-ray diffraction of very coarse sieved WTC PM (fraction. Analysis of WTC PM2.5 using X-ray fluorescence, neutron activation analysis, and inductively coupled plasma spectrometry showed high levels of calcium (range, 22-33%) and sulfur (37-43% as sulfate) and much lower levels of transition metals and other elements. Aqueous extracts of WTC PM2.5 were basic (pH range, 8.9-10.0) and had no evidence of significant bacterial contamination. Levels of carbon were relatively low, suggesting that combustion-derived particles did not form a significant fraction of these samples recovered in the immediate aftermath of the destruction of the towers. Because gypsum and calcite are known to cause irritation of the mucus membranes of the eyes and respiratory tract, inhalation of high doses of WTC PM2.5 could potentially cause toxic respiratory effects.

    We report the first results from our program to examine the metallicity distribution of the Milky Way nuclear star cluster connected to SgrA*, with the goal of inferring the star formation and enrichment history of this system, as well as its connection and relationship with the central 100 pc of the bulge/bar system. We present the first high resolution (R~24,000), detailed abundance analysis of a K=10.2 metal-poor, alpha-enhanced red giant projected at 1.5 pc from the Galactic Center, using NIRSPEC on Keck II. A careful analysis of the dynamics and color of the star locates it at about 26 pc line-of-sight distance in front of the nuclear cluster. It probably belongs to one of the nuclear components (cluster or disk), not to the bar-bulge or classical disk. A detailed spectroscopic synthesis, using a new linelist in the K band, finds [Fe/H]~-1.0 and [alpha/Fe]~+0.4, consistent with stars of similar metallicity in the bulge. As known giants with comparable [Fe/H] and alpha enhancement are old, we conclude tha...

  17. Analysis of the access patterns at GSFC distributed active archive center

    1996-01-01

    The Goddard Space Flight Center (GSFC) Distributed Active Archive Center (DAAC) has been operational for more than two years. Its mission is to support existing and pre Earth Observing System (EOS) Earth science datasets, facilitate the scientific research, and test Earth Observing System Data and Information System (EOSDIS) concepts. Over 550,000 files and documents have been archived, and more than six Terabytes have been distributed to the scientific community. Information about user request and file access patterns, and their impact on system loading, is needed to optimize current operations and to plan for future archives. To facilitate the management of daily activities, the GSFC DAAC has developed a data base system to track correspondence, requests, ingestion and distribution. In addition, several log files which record transactions on Unitree are maintained and periodically examined. This study identifies some of the users' requests and file access patterns at the GSFC DAAC during 1995. The analysis is limited to the subset of orders for which the data files are under the control of the Hierarchical Storage Management (HSM) Unitree. The results show that most of the data volume ordered was for two data products. The volume was also mostly made up of level 3 and 4 data and most of the volume was distributed on 8 mm and 4 mm tapes. In addition, most of the volume ordered was for deliveries in North America although there was a significant world-wide use. There was a wide range of request sizes in terms of volume and number of files ordered. On an average 78.6 files were ordered per request. Using the data managed by Unitree, several caching algorithms have been evaluated for both hit rate and the overhead ('cost') associated with the movement of data from near-line devices to disks. The algorithm called LRU/2 bin was found to be the best for this workload, but the STbin algorithm also worked well.

  18. Activation Strain Analysis of SN2 Reactions at C, N, O, and F Centers.

    2017-02-02

    Fundamental principles that determine chemical reactivity and reaction mechanisms are the very foundation of chemistry and many related fields of science. Bimolecular nucleophilic substitutions (SN2) are among the most common and therefore most important reaction types. In this report, we examine the trends in the SN2 reactions with respect to increasing electronegativity of the reaction center by comparing the well-studied backside SN2 Cl(-) + CH3Cl with similar Cl(-) substitutions on the isoelectronic series with the second period elements N, O, and F in place of C. Relativistic (ZORA) DFT calculations are used to construct the gas phase reaction potential energy surfaces (PES), and activation strain analysis, which allows decomposition of the PES into the geometrical strain and interaction energy, is employed to analyze the observed trends. We find that SN2@N and SN2@O have similar PES to the prototypical SN2@C, with the well-defined reaction complex (RC) local minima and a central barrier, but all stationary points are, respectively, increasingly stable in energy. The SN2@F, by contrast, exhibits only a single-well PES with no barrier. Using the activation strain model, we show that the trends are due to the interaction energy and originate mainly from the decreasing energy of the empty acceptor orbital (σ*A-Cl) on the reaction center A in the order of C, N, O, and F. The decreasing steric congestion around the central atom is also a likely contributor to this trend. Additional decomposition of the interaction energy using Kohn-Sham molecular orbital (KS-MO) theory provides further support for this explanation, as well as suggesting electrostatic energy as the primary reason for the distinct single-well PES profile for the FCl reaction.

    Full Text Available What happens when someone rings an emergency hotline for help? How is the emergency handled? How does the emergency service swing into action? Prompt and competent intervention and assessment of the gravity of the situation in a few crucial seconds: these are the quality standards that regulate the organization of emergency operations centers. For a number of years various groups of social science researchers have carried forward a program for the systematic study of work using ethnographic and naturalistic methods of analysis. An interest in work is certainly nothing new in the social sciences, and in sociology in particular. What is new, though, is the particular analytical viewpoint from which such research is now conducted. This program has dispensed with large-scale theorization and has concentrated on the empirical study of activities and practices, achieving an unprecedented level of detail and analytical fineness. Indeed, only by proceeding at this fine level of detail—made possible by the use of videorecordings—has it been possible to document the extraordinary and subtle collaborative production of work, and to do so at a level which extends well beyond the conscious awareness of people in their everyday routine. This aspect concerns in particular the capacity of the latest generation of studies of work to document the tacit procedures and forms of common-sense reasoning involved in the performance of tasks in concrete work settings. This paper focuses on the ways in which the dispatch is done in a medical emergency operation center. Although we know a great deal about the interaction between caller and call-taker from previous research, we know much less about the social organization that makes the dispatch possible. The data analyzed in this paper derive from a research project in which I have been engaged for a number of years on operation centers for the 118 emergency telephone number in Italy.

    Heterodimer mutant reaction centers (RCs) of Blastochloris viridis were crystallized using microfluidic technology. In this mutant, a leucine residue replaced the histidine residue which had acted as a fifth ligand to the bacteriochlorophyll (BChl) of the primary electron donor dimer M site (HisM200). With the loss of the histidine-coordinated Mg, one bacteriochlorophyll of the special pair was converted into a bacteriopheophytin (BPhe), and the primary donor became a heterodimer supermolecule. The crystals had dimensions 400 x 100 x 100 {micro}m, belonged to space group P4{sub 3}2{sub 1}2, and were isomorphous to the ones reported earlier for the wild type (WT) strain. The structure was solved to a 2.5 {angstrom} resolution limit. Electron-density maps confirmed the replacement of the histidine residue and the absence of Mg. Structural changes in the heterodimer mutant RC relative to the WT included the absence of the water molecule that is typically positioned between the M side of the primary donor and the accessory BChl, a slight shift in the position of amino acids surrounding the site of the mutation, and the rotation of the M194 phenylalanine. The cytochrome subunit was anchored similarly as in the WT and had no detectable changes in its overall position. The highly conserved tyrosine L162, located between the primary donor and the highest potential heme C{sub 380}, revealed only a minor deviation of its hydroxyl group. Concomitantly to modification of the BChl molecule, the redox potential of the heterodimer primary donor increased relative to that of the WT organism (772 mV vs. 517 mV). The availability of this heterodimer mutant and its crystal structure provides opportunities for investigating changes in light-induced electron transfer that reflect differences in redox cascades.

    We report a meta-analysis on the relationship between in-group bias and culture. Our focus is on whether broad macro-contextual variables influence the extent to which individuals favour their in-group. Data from 21,266 participants from 18 societies included in experimental and survey studies were available. Using Hofstede's (1980) and Schwartz (2006) culture-level predictors in a 3-level mixed-effects meta-analysis, we found strong support for the uncertainty-reduction hypothesis. An interaction between Autonomy and real vs artificial groups suggested that in low autonomy contexts, individuals show greater in-group bias for real groups. Implications for social identity theory and intergroup conflict are outlined.

  3. Turnover and heterogeneity in top management networks - A demographic analysis of two Swedish business groups

    2008-09-01

    Full Text Available A theory based on the demography of top management teams is used to explain membership turnover in two Swedish business groups, network analysis being used to define group membership. The results suggest these business groups possess a combination of financial and industrial experience as a group resource and the socialising strategy of control as a force counteracting the conflict-producing force of heterogeneity. An organisational demographic perspective focusing on opposing forces of heterogeneity and homogeneity is developed. It is shown that the perspective can be applied both to formal organisations and to informal ones such as networks.

    2017-01-01

    Background Person-centered care is a holistic and integrative approach designed to maintain well-being and quality of life for people with dementia, and it includes the elements of care, the individual, the carers, and the family. Aim A systematic literature review and meta-analysis were undertaken to investigate the effectiveness of person-centered care for people with dementia. Methods Literature searches were undertaken using six databases including Medline, EMBASE, CINAHL, PsycINFO, Cochrane Database, and KoreaMed using the following keywords: cognition disorder, dementia, person-centered care, patient-centered care, client-centered care, relationship-centered care, and dementia care. The searches were limited to interventional studies written in English and Korean and included randomized controlled studies and noncontrolled studies for people with dementia living in any setting. Results Nineteen interventional studies, including 3,985 participants, were identified. Of these, 17 studies were from long-term care facilities and two studies were from homecare settings. The pooled data from randomized controlled studies favored person-centered care in reducing agitation, neuropsychiatric symptoms, and depression and improving the quality of life. Subgroup analysis identified greater effectiveness of person-centered care when implemented for people with less severe dementia. For agitation, short-term interventions had a greater effect (standardized mean difference [SMD]: −0.434; 95% conference interval [CI]: −0.701 to −0.166) than long-term interventions (SMD: −0.098; 95% CI: −0.190 to 0.007). Individualized activities resulted in a significantly greater beneficial effect than standard care (SMD: 0.513; 95% CI: −0.994 to −0.032). However, long-term, staff education, and cultural change interventions had a greater effect on improving the quality of life for people with dementia (SMD: 0.191; 95% CI: 0.079 to 0.302). Conclusion This systematic review and

    Regional gray matter (GM) atrophy in multiple sclerosis (MS) at disease onset and its temporal variation can provide objective information regarding disease evolution. An automated pipeline for estimating atrophy of various GM structures was developed using tensor based morphometry (TBM) and implemented on a multi-center sub-cohort of 1008 relapsing remitting MS (RRMS) patients enrolled in a Phase 3 clinical trial. Four hundred age and gender matched healthy controls were used for comparison. Using the analysis of covariance, atrophy differences between MS patients and healthy controls were assessed on a voxel-by-voxel analysis. Regional GM atrophy was observed in a number of deep GM structures that included thalamus, caudate nucleus, putamen, and cortical GM regions. General linear regression analysis was performed to analyze the effects of age, gender, and scanner field strength, and imaging sequence on the regional atrophy. Correlations between regional GM volumes and expanded disability status scale (EDSS) scores, disease duration (DD), T2 lesion load (T2 LL), T1 lesion load (T1 LL), and normalized cerebrospinal fluid (nCSF) were analyzed using Pearson’s correlation coefficient. Thalamic atrophy observed in MS patients compared to healthy controls remained consistent within subgroups based on gender and scanner field strength. Weak correlations between thalamic volume and EDSS (r = −0.133; p < 0.001) and DD (r = −0.098; p = 0.003) were observed. Of all the structures, thalamic volume moderately correlated with T2 LL (r = −0.492; p-value < 0.001), T1 LL (r = −0.473; p-value < 0.001) and nCSF (r = −0.367; p-value < 0.001). PMID:25787188

    Full Text Available On the basis of several examples from our longitudinal study "Transitions to Employment," dealing with the shaping of biography of young adults and typical transition-patterns from education to employment, we discuss the use of a text databank in the evaluation of problem-centered interviews. First, we explain the structure of the project's "databank of biographical interviews with young adults" which is founded on a thematic and temporarily differentiating system of categories recording job- and family-related actions and orientations. We present different ways of using the databank in qualitative evaluation. The manner how certain cases and categories of the databank are selected and included in the analysis depends on the objective and the problem's complexity. Our examples show that the use of a databank is an important possibility to support the evaluation of qualitative interviews, facilitating a thematic directed access and thus allowing the handling of data which are particularly extensive.

    Full Text Available Abstract Background An estimated up to 7% of high-risk cardiac surgery patients return to the operating room for bleeding. Aprotinin was used extensively as an antifibrinolytic agent in cardiac surgery patients for over 15 years and it showed efficacy in reducing bleeding. Aprotinin was removed from the market by the U.S. Food and Drug Administration after a large prospective, randomized clinical trial documented an increased mortality risk associated with the drug. Further debate arose when a meta-analysis of 211 randomized controlled trials showed no risk of renal failure or death associated with aprotinin. However, only patients with normal kidney function have been studied. Methods In this study, we look at a single center clinical trial using patients with varying degrees of baseline kidney function to answer the question: Does aprotinin increase odds of death given varying levels of preoperative kidney dysfunction? Results Based on our model, aprotinin use was associated with a 3.8-fold increase in odds of death one year later compared to no aprotinin use with p-value = 0.0018, regardless of level of preoperative kidney dysfunction after adjusting for other perioperative variables. Conclusions Lessons learned from our experience using aprotinin in the perioperative setting as an antifibrinolytic during open cardiac surgery should guide us in testing future antifibrinolytic drugs for not only efficacy of preventing bleeding, but for overall safety to the whole organism using long-term clinical outcome studies, including those with varying degree of baseline kidney function.

    Full Text Available The purpose of this article is to define a maintenance strategy for an electric induction furnace, installed on a special steels Foundry. The research method was the quantitative modeling. The proposed method is based on Reliability-Centered Maintenance (RCM, applied to industrial equipment. Quantitative analysis of reliability, availability and maintainability were used as support the definition of the maintenance strategy of the equipment. For research, historical data were collected from time-to-repair (TTR and time between failures (TBF of the equipment under consideration. Supported by ProConf 2000 software, most appropriate distributions have been identified and modeled to TTR (lognormal and TBF (Weibull. With the results, availability of equipment Av = 98,18% and form factor g = 1 of the Weibull distribution were calculated. It was possible to find a position for the equipment on the bathtub curve, in the maturity phase and define the best maintenance strategy for this case, the predictive maintenance. Finally, the current strategy was discussed and development suggestions were presented to this strategy.

    larger regional or national picture of precipitating weather systems. Composites, horizontal and vertical crosssections, and combinations thereof are easily displayed using as little as one line of code. MMM-Py can also write to the native MRMS binary format, and sub-sectioning of tiles (or multiple stitched tiles) is anticipated to be in place by the time of this meeting. Thus, MMM-Py also can be used to power the creation of custom mosaics for targeted regional studies. Overlays of other data (e.g., lightning observations) are easily accomplished. Demonstrations of MMM-Py, including the creation of animations, will be shown. Finally, Marshall has done significant work to interface Python-based analysis routines with the U.S. Department of Energy's Py-ART software package for radar data ingest, processing, and analysis. One example of this is the Python Turbulence Detection Algorithm (PyTDA), an MSFC-based implementation of the National Center for Atmospheric Research (NCAR) Turbulence Detection Algorithm (NTDA) for the purposes of convective-scale analysis, situational awareness, and forensic meteorology. PyTDA exploits Py-ART's radar data ingest routines and data model to rapidly produce aviation-relevant turbulence estimates from Doppler radar data. Work toward processing speed optimization and better integration within the Py-ART framework will be highlighted. Python-based analysis within the Py-ART framework is also being done for new research related to intercomparison of ground-based radar data with satellite estimates of ocean winds, as well as research on the electrification of pyrocumulus clouds.

    [Abridged] The Study Analysis Group 8 of the NASA Exoplanet Analysis Group was convened to assess the current capabilities and the future potential of the precise radial velocity (PRV) method to advance the NASA goal to "search for planetary bodies and Earth-like planets in orbit around other stars.: (U.S. National Space Policy, June 28, 2010). PRVs complement other exoplanet detection methods, for example offering a direct path to obtaining the bulk density and thus the structure and composition of transiting exoplanets. Our analysis builds upon previous community input, including the ExoPlanet Community Report chapter on radial velocities in 2008, the 2010 Decadal Survey of Astronomy, the Penn State Precise Radial Velocities Workshop response to the Decadal Survey in 2010, and the NSF Portfolio Review in 2012. The radial-velocity detection of exoplanets is strongly endorsed by both the Astro 2010 Decadal Survey "New Worlds, New Horizons" and the NSF Portfolio Review, and the community has recommended robust...

    Highlights: • Periinterventional complications in 7.5% of patients with intracranial artery stenting. • 2.5% of periinterventional complications were perforator strokes. • 3.8% of patients developed a hemorrhagic stroke due to reperfusion injury. • Complications could be reduced by individualized measures to prevent perforator stroke or reperfusion injury. - Abstract: Background and purpose: Treatment of symptomatic intracranial atherosclerotic disease by angioplasty and stenting (PTAS) is limited by a high rate of periinterventional strokes. We performed a detailed analysis of these strokes at our center in order to identify strategies to reduce the risk of periinterventional complications. Methods: Case records and imaging data of 80 patients with a symptomatic 70–99% stenosis of a major intracranial artery treated with PTAS between July 2007 and December 2013 were reviewed. All patients had a sufficient response to aspirin and clopidogrel. Periinterventional strokes were categorized as either ischemic (perforator territory, distal embolic or delayed stent thrombosis) or hemorrhagic (intraparenchymal, subarachnoid). Results: Periinterventional complications occurred in 6/80 (7.5%) patients, consisting of 2 ischemic strokes (2.5%, both perforator territory), 3 hemorrhagic strokes (3.8%, 2 intraparenchymal due to reperfusion injury, 1 subarachnoid due to vessel rupture) and one death (1.3%) unrelated to stroke. All strokes occurred within 24 h after PTAS. Conclusion: Our retrospective data analysis suggests that the risk of periinterventional stroke after PTAS of symptomatic intracranial atherosclerotic disease might be reduced by sufficient antiplatelet therapy and optimized management of patients with high risk for reperfusion injury or perforator strokes, including selection of a stenting device adapted to individual vessel morphology.

    Recurrence quantification analysis (RQA) can extract the dynamics of postural control from center of pressure (CoP) data by quantifying the system's repeatability, complexity, and local dynamic stability through several variables. Computation of these variables requires the selection of suitable embedding parameters for state space reconstruction (i.e. time delay and embedding dimension); however, it is unclear how the parameters influence RQA variables when examining noisy CoP data. This study evaluated the sensitivity of RQA variables to embedding parameter values and noise level, and assessed methods of selecting embedding parameters for CoP data. Five healthy male subjects maintained quiet stance for 30s while the anterior-posterior CoP was measured. The effect of noise was evaluated by adding uniform white noise of increasing amplitude to the raw CoP signal. The magnitude of all RQA variables decreased with increasing noise amplitude for all subjects. A sensitivity analysis was performed by systematically altering the embedding parameters for the raw data with and without a selected level of added noise. The key result was that, for all subjects, the RQA variables were sensitive to the embedding parameter values and the level of noise in the CoP data. Finally, the performance of false nearest neighbors and average displacement algorithms for choosing embedding parameters was evaluated. Both methods gave clear and consistent results for all subjects with either raw or noisy data. The results suggest that careful selection of embedding parameters is essential when using RQA to examine postural control based on noisy CoP data.

    The American Burn Association instituted a burn center verification process to ensure optimal care for patients with burn injury. Limited data exist regarding differences in admissions and outcomes between verified (VC) and nonverified burn centers (NVC). The study purpose was to compare demographics, treatment, and outcomes of VC and NVC. The five VC were compared with the 12 NVC using data from California's discharge database for the year 2003. A total of 2867 patients were admitted to a burn center, 1645 to NVC (132/center), and 1222 (244/center) to VC. NVC admitted 1496 (91%) of their patients from local area and 118 (7%) from other acute care hospitals; in contrast, 948 (78%) of VC patients were local and 253 (21%) were transfers from other acute care hospitals. VCs admitted twice as many burns > or =80% total body surface area as NVC. VCs admitted more patients with face burns (18% VC vs 14% NVC, P NVC P NVC, P NVC and 4% in VC. During the study period verified centers in California admitted more patients per center and treated more severely injured patients than nonverified centers. Despite these differences, VC had mortality rates comparable to their nonverified counterparts. These findings support the need for additional studies evaluating the impact of verification on burn care.

The searches were limited to interventional studies written in English and Korean and included randomized controlled studies and noncontrolled studies for people with dementia living in any setting.Results: Nineteen interventional studies, including 3,985 participants, were identified. Of these, 17 studies were from long-term care facilities and two studies were from homecare settings. The pooled data from randomized controlled studies favored person-centered care in reducing agitation, neuropsychiatric symptoms, and depression and improving the quality of life. Subgroup analysis identified greater effectiveness of person-centered care when implemented for people with less severe dementia. For agitation, short-term interventions had a greater effect (standardized mean difference [SMD]: -0.434; 95% conference interval [CI]: -0.701 to -0.166 than long-term interventions (SMD: -0.098; 95% CI: -0.190 to 0.007.

    This study focuses on the association between the ABO blood group system and the risk of gastric cancer or Helicobacter pylori infection. The data for the ABO blood group was collected from 1045 cases of gastric cancer, whereby the patient underwent a gastrectomy in Ruijin Hospital, Shanghai. The information on the ABO blood group from 53,026 healthy blood donors was enrolled as control. We searched the Pubmed database on the relationship between ABO blood groups and gastric cancer risk for meta-analysis. In our case-control study, the risk of gastric cancer in blood group A was significantly higher than that in non-A groups (O, B and AB) (odd ratio, OR1.34; 95% confidential interval, CI 1.25-1.44). Compared with non-O groups (A, B and AB), individuals with blood group O demonstrated a reduced risk of gastric cancer (OR = 0.80; 95% CI 0.72-0.88). The proportion of H. pylori infection in blood group A individuals was significantly higher than that in non-A blood groups (OR = 1.42; 95% CI 1.05-1.93). We further combined our data with the published data of others, and crossreferenced the risk of gastric cancer with the blood type, finding consistent evidence that gastric cancer risk in the blood A group was higher than that in the non-A groups (OR = 1.11; 95% CI 1.07-1.15), and that blood type O individuals were consistently shown gastric cancer risk reduction (OR = 0.91; 95% CI 0.89-0.94). Our study concluded that there was a slightly increased risk of gastric cancer in blood group A individuals, and people with blood type A are more prone to be infected by H. pylori than other ABO blood type individuals, whereas, a slightly decreased risk of gastric cancer was identified in blood type O individuals.

  7. A unified framework for group independent component analysis for multi-subject fMRI data.

    Independent component analysis (ICA) is becoming increasingly popular for analyzing functional magnetic resonance imaging (fMRI) data. While ICA has been successfully applied to single-subject analysis, the extension of ICA to group inferences is not straightforward and remains an active topic of research. Current group ICA models, such as the GIFT [Calhoun, V.D., Adali, T., Pearlson, G.D., Pekar, J.J., 2001. A method for making group inferences from functional MRI data using independent component analysis. Hum. Brain Mapp. 14, 140-151.] and tensor PICA [Beckmann, C.F., Smith, S.M., 2005. Tensorial extensions of independent component analysis for multisubject FMRI analysis. Neuroimage 25, 294-311.], make different assumptions about the underlying structure of the group spatio-temporal processes and are thus estimated using algorithms tailored for the assumed structure, potentially leading to diverging results. To our knowledge, there are currently no methods for assessing the validity of different model structures in real fMRI data and selecting the most appropriate one among various choices. In this paper, we propose a unified framework for estimating and comparing group ICA models with varying spatio-temporal structures. We consider a class of group ICA models that can accommodate different group structures and include existing models, such as the GIFT and tensor PICA, as special cases. We propose a maximum likelihood (ML) approach with a modified Expectation-Maximization (EM) algorithm for the estimation of the proposed class of models. Likelihood ratio tests (LRT) are presented to compare between different group ICA models. The LRT can be used to perform model comparison and selection, to assess the goodness-of-fit of a model in a particular data set, and to test group differences in the fMRI signal time courses between subject subgroups. Simulation studies are conducted to evaluate the performance of the proposed method under varying structures of group spatio

    Of the 39 species composing the Xiphinema americanum group, 14 were described originally from North America and two others have been reported from this region. Many species are very similar morphologically and can be distinguished only by a difficult comparison of various combinations of some morphometric characters. Study of morphometrics of 49 populations, including the type populations of the 39 species attributed to this group, by principal component analysis and hierarchical cluster analysis placed the populations into five subgroups, proposed here as the X. brevicolle subgroup (seven species), the X. americanum subgroup (17 species), the X. taylori subgroup (two species), the X. pachtaicum subgroup (eight species), and the X. lambertii subgroup (five species).

    We extend the concept of frame multiresolution analysis to a locally compact abelian group and use it to define certain weighted Banach spaces and the spaces of their antifunctionals. We define analysis and synthesis operators on these spaces and establish the continuity of their composition. Also, we prove a general result to characterize infinite trees in the above Banach spaces of antifunctionals. This paper paves the way for the study of corresponding problems associated with some other types of Banach spaces on locally compact abelian groups including modulation spaces.

    The detection of polymorphism is the basis of blood group genotyping and phenotype prediction. Genotyping may be useful to determine blood groups when serologic results are unclear. The development and application of different methods for blood group genotyping may be needed as a substitute for blood group typing. The purpose of this study is to establish an approach for blood group genotyping based on a melting curve analysis of real-time polymerase chain reaction (PCR). Using DNA extracted from whole blood, we developed and validated a DNA typing method for detecting DO*01/DO*02, DO*01/DI*02, LU*01/LU*02, and GYPB*03/GYBP*04 alleles using a melting curve analysis. All assays were confirmed with a commercial reagent containing sequence-specific primers (PCR-SSP), and a cohort of the samples was confirmed with sequencing. Results for all blood groups were within the range of specificity and assay variability. Genotypes of 300 blood donors were fully consistent with PCR-SSP data. The obtained genotype distribution is in complete concordance with existing data for the Chinese population. There are several advantages for this approach of blood group genotyping: lower contamination rates with PCR products in this laboratory, ease of performance, automation potential, and rapid cycling time.

    An image analysis biomonitoring system was used to evaluate sublethal effects of pH on the mean swimming velocity of zebrafish. Responses to stress were tested comparing individual and group responses. Group analysis indicated no effect for all acid pH and for pH 9.0-9.5. Individual analysis indicated behavioral differences for most acid pH and higher than 9.5. Sensitivity to sublethal pH was best assessed when using individual analysis. Zebrafish decreased hyperactivity and increased hypoactivity with more acid or alkaline pH. Individual approach allowed to determine hyperactivity or hypoactivity and the species' thresholds of exposure, which is critical for the management of impairments.

    Background In this article, we reviewed the training results of medical students using the Microvascular Research Center Training Program (MRCP), and proposed an ideal microsurgical training program for all individuals by analyzing the training results of medical students who did not have any surgical experience. Methods As of 2015, a total of 29 medical students completed the MRCP. In the most recent 12 medical students, the number of trials performed for each training stage and the number of rats needed to complete the training were recorded. Additionally, we measured the operating time upon finishing stage 5 for the recent six medical students after it became a current program. Results The average operating time upon finishing stage 5 for the recent six medical students was 120 minutes ± 11 minutes (standard deviation [SD]). The average vascular anastomosis time (for the artery and vein) was 52 minutes ± 2 minutes (SD). For the most recent 12 medical students, there was a negative correlation between the number of trials performed in the non-rat stages (stages 1-3) and the number of rats used in the rat stages (stages 4-5). Conclusion Analysis of the training results of medical students suggests that performing microsurgery first on silicon tubes and chicken wings saves animals' lives later during the training program. We believe that any person can learn the technique of microsurgery by performing 7 to 8 hours of training per day over a period of 15 days within this program setting.

    This paper presents a case study of an approach to sustainable software architecture that has been successfully applied over a period of 10 years to astronomy software services at the NASA Infrared Processing and Analysis Center (IPAC), Caltech (http://www.ipac.caltech.edu). The approach was developed in response to the need to build and maintain the NASA Infrared Science Archive (http://irsa.ipac.caltech.edu), NASA's archive node for infrared astronomy datasets. When the archive opened for business in 1999 serving only two datasets, it was understood that the holdings would grow rapidly in size and diversity, and consequently in the number of queries and volume of data download. It was also understood that platforms and browsers would be modernized, that user interfaces would need to be replaced and that new functionality outside of the scope of the original specifications would be needed. The changes in scientific functionality over time are largely driven by the archive user community, whose interests are represented by a formal user panel. The approach has been extended to support four more major astronomy archives, which today host data from more than 40 missions and projects, to support a complete modernization of a powerful and unique legacy astronomy application for co-adding survey data, and to support deployment of Montage, a powerful image mosaic engine for astronomy. The approach involves using a component-based architecture, designed from the outset to support sustainability, extensibility and portability. Although successful, the approach demands careful assessment of new and emerging technologies before adopting them, and attention to a disciplined approach to software engineering and maintenance. The paper concludes with a list of best practices for software sustainability that are based on 10 years of experience at IPAC.

    Full Text Available Four black belt throwers (tori and one black belt faller (uke were filmed and analyzed in three-dimensions using two video cameras (JVC 60 Hz and motion analysis software. Average linear momentum in the anteroposterior (x, vertical (y, and mediolateral (z directions and average resultant impulse of uke's center of mass (COM were investigated for three different throwing techniques; harai-goshi (hip throw, seoi-nage (hand throw, and osoto-gari (leg throw. Each throw was broken down into three main phases; kuzushi (balance breaking, tsukuri (fit-in, and kake (throw. For the harai-goshi and osoto-gari throws, impulse measurements were the largest within kuzushi and tsukuri phases (where collision between tori and uke predominantly occurs. Both throws indicated an importance for tori to create large momentum prior to contact with uke. The seoi-nage throw demonstrated the lowest impulse and maintained forward momentum on the body of uke throughout the entire throw. The harai-goshi and osoto-gari are considered power throws well-suited for large and strong judo players. The seoi-nage throw is considered more technical and is considered well-suited for shorter players with good agility. A form of resistance by uke was found during the kuzushi phase for all throws. The resistance which can be initiated by tori's push or pull allows for the tsukuri phase to occur properly by freezing uke for a good fit-in. Strategies for initiating an effective resistance include initiating movement of uke so that their COM is shifted to their left (for right handed throw by incorporating an instantaneous "snap pull" with the pulling hand during kuzushi to create an opposite movement from uke

    Full Text Available Istanbul historical city center is going through a provincial transformation by quick population increase, multicentered city development, developing tourism and trade feature pressures as well as selection of location for housing. Provincial transformation is briefly described as; an action plan integrating with the city and urban people, prepared to increase life quality based on strategic development plan and within the provincial development vision for the nonfunctional, old and worn provincial pieces unable to fulfill physical, social and economic development dynamics and new requirements. Objective of this study is to find out factors affecting provincial transformation that are observed in research district and positive negative effect ratios based on regression analysis. Research district Sultanahmet and surrounding area located between Divan Yolu Street and Topkapı Palace and Marmara Sea, which is considered among UNESCO Global Heritage Areas, having intensive cultural assets, transforming pursuant to tourism and trade feature pressure, preserving most of its authentic housing texture, worn out as well as observed to be a qualified housing location choice of people with high socio-economic and educational class. It is concluded that the urban transformation resulting from the dynamism in the historical, physical and socioeconomically structure of the space in the research area is weighted with the accommodation and commercial place selections, there are influences of the culture asset structure, some part of the functions being in the place selection and the positive and negative reflections of the quantitative and qualitative characteristics of the focal points on the transformation which is followed on the area and also the land-plot unit price value directs the selections in part.

  6. A cladistic analysis of Aristotle's animal groups in the Historia animalium.

    von Lieven, Alexander Fürst; Humar, Marcel

    2008-01-01

    The Historia animalium (HA) of Aristotle contains an extraordinarily rich compilation of descriptions of animal anatomy, development, and behaviour. It is believed that Aristotle's aim in HA was to describe the correlations of characters rather than to classify or define animal groups. In order to assess if Aristotle, while organising his character correlations, referred to a pre-existing classification that underlies the descriptions in HA, we carried out a cladistic analysis according to the following procedure: by disentangeling 147 species and 40 higher taxa-designations from 157 predicates in the texts, we transcribed Aristotle's descriptions on anatomy and development of animals in books I-V of HA into a character matrix for a cladistic analysis. By analysing the distribution of characters as described in his books, we obtained a non-phylogenetic dendrogram displaying 58 monophyletic groups, 29 of which have equivalents among Aristotle's group designations. Eleven Aristotelian groupings turned out to be non-monophyletic, and six of them are inconsistent with the monophyletic groups. Twelve of 29 taxa without equivalents in Aristotle's works have equivalents in modern classifications. With this analysis we demonstate there exists a fairly consistent underlying classification in the zoological works of Aristotle. The peculiarities of Aristotle's character basis are discussed and the dendrogram is compared with a current phylogenetic tree.

  7. EEGIFT: Group Independent Component Analysis for Event-Related EEG Data

    Directory of Open Access Journals (Sweden)

    Tom Eichele

    2011-01-01

    Full Text Available Independent component analysis (ICA is a powerful method for source separation and has been used for decomposition of EEG, MRI, and concurrent EEG-fMRI data. ICA is not naturally suited to draw group inferences since it is a non-trivial problem to identify and order components across individuals. One solution to this problem is to create aggregate data containing observations from all subjects, estimate a single set of components and then back-reconstruct this in the individual data. Here, we describe such a group-level temporal ICA model for event related EEG. When used for EEG time series analysis, the accuracy of component detection and back-reconstruction with a group model is dependent on the degree of intra- and interindividual time and phase-locking of event related EEG processes. We illustrate this dependency in a group analysis of hybrid data consisting of three simulated event-related sources with varying degrees of latency jitter and variable topographies. Reconstruction accuracy was tested for temporal jitter 1, 2 and 3 times the FWHM of the sources for a number of algorithms. The results indicate that group ICA is adequate for decomposition of single trials with physiological jitter, and reconstructs event related sources with high accuracy.

    Full Text Available Bioimpedance analysis has been widely used to estimate a hydration state, lean and fat mass in haemodialysis patients. The aim of our study was to investigate the validity and usefulness of bioimpedance analysis in routine dialysis practice. Last two years we used the body composition monitoring (BCM, Fresenius Medical Care, method based on whole body multifrequency bioimpedance spectroscopy (BIS, compared with traditional clinical data. For BIS data verification, hydration status of 32 stable HD patients with dialysis vintage more than 3 years and clinically well established dry weight were studied. Only in three cases BIS data seems underestimated in serial measurements. Next step, 28 healthy subjects and 116 dialysis patients were studied. Total body water and extracellular volume (ECV were significantly higher in dialysis group (P<0.01, and there was not any difference in intracellular volume (ICV. Mean AP was similar in patients with moderate (<15% and massive (>15% relative overhydration (RO = overhydration / ECV, at the same time, average number of antihypertensive medications was significantly higher in more overhydrated patients (3.1 vs 1.2. In clinical practice RO is more convenient indicator as compared to standard overhydration volume /dry weight ratio. Mutual application of the BIS and blood volume monitoring allows more rapid and safe dry weight achievement. BIS was useful tool for hydration status monitoring in routine haemodialysis practice, and further work need to be done to clarify BIS validity for nutritional status estimation.

  15. Multiple Group Testing Procedures for Analysis of High-Dimensional Genomic Data

    Ko, Hyoseok; Kim, Kipoong

    2016-01-01

    In genetic association studies with high-dimensional genomic data, multiple group testing procedures are often required in order to identify disease/trait-related genes or genetic regions, where multiple genetic sites or variants are located within the same gene or genetic region. However, statistical testing procedures based on an individual test suffer from multiple testing issues such as the control of family-wise error rate and dependent tests. Moreover, detecting only a few of genes associated with a phenotype outcome among tens of thousands of genes is of main interest in genetic association studies. In this reason regularization procedures, where a phenotype outcome regresses on all genomic markers and then regression coefficients are estimated based on a penalized likelihood, have been considered as a good alternative approach to analysis of high-dimensional genomic data. But, selection performance of regularization procedures has been rarely compared with that of statistical group testing procedures. In this article, we performed extensive simulation studies where commonly used group testing procedures such as principal component analysis, Hotelling's T2 test, and permutation test are compared with group lasso (least absolute selection and shrinkage operator) in terms of true positive selection. Also, we applied all methods considered in simulation studies to identify genes associated with ovarian cancer from over 20,000 genetic sites generated from Illumina Infinium HumanMethylation27K Beadchip. We found a big discrepancy of selected genes between multiple group testing procedures and group lasso.

    2013-01-01

    Full Text Available In order to calculate negative skin friction (NSF of pile group embedded in a consolidating soil, the dragload calculating formulas of single pile were established by considering Davis one-dimensional nonlinear consolidation soils settlement and hyperbolic load-transfer of pile-soil interface. Based on effective influence area theory, a simple semiempirical mathematical model of analysis for predicting the group effect of pile group under dragload was described. The accuracy and reliability of mathematical models built in this paper were verified by practical engineering comparative analysis. Case studies were studied, and the prediction values were found to be in good agreement with those of measured values. Then, the influences factors, such as, soil consolidation degree, the initial volume compressibility coefficient, and the stiffness of bearing soil, were analyzed and discussed. The results show that the mathematical models considering nonlinear soil consolidation and group effect can reflect the practical NSF of pile group effectively and accurately. The results of this paper can provide reference for practical pile group embedded in consolidating soil under NSF design and calculation.

    We present VLT spectroscopic observations of 7 discovered galaxy groups between 0.3groups were selected from the Strong Lensing Legacy Survey (SL2S), a survey that consists in a systematic search for strong lensing systems in the Canada-France-Hawaii Telescope Legacy Survey (CFHTLS). We give details about the target selection, spectroscopic observations and data reduction for the first release of confirmed SL2S groups. The dynamical analysis of the systems reveals that they are gravitationally bound structures, with at least 4 confirmed members and velocity dispersions between 300 and 800 km/s. Their virial masses are between 10^13 and 10^14 M_sun, and so can be classified as groups or low mass clusters. Most of the systems are isolated groups, except two of them that show evidence of an ongoing merger of two sub-structures. We find a good agreement between the velocity dispersions estimated from the analysis of the kinematics of group galaxies and the weak lensing measurements, and conclude...

    2015-01-01

    We have developed a new statistical framework for group-level event-related potential (ERP) analysis in EEGLAB. The framework calculates the variance of scalp channel signals accounted for by the activity of homogeneous clusters of sources found by independent component analysis (ICA). When ICA data decomposition is performed on each subject's data separately, functionally equivalent ICs can be grouped into EEGLAB clusters. Here, we report a new addition (statPvaf) to the EEGLAB plug-in std_envtopo to enable inferential statistics on main effects and interactions in event related potentials (ERPs) of independent component (IC) processes at the group level. We demonstrate the use of the updated plug-in on simulated and actual EEG data.

    Objective: Injuries are common and important problem in Tehran, capital of Iran. Although therapeutic centers are not essentially established following the constructional principles of developed countries, the present opportunities and equipments have to be used properly. We should recognize and reduce the deficits based on the global standards.This study deliberates the trauma resources and capacities in university hospitals of Tehran based on Arizona trauma center standards, which are suitable for the assessment of trauma centers.Methods: Forty-one university hospitals in Tehran were evaluated for their conformity with "Arizona trauma center standards" in 2008. A structured interview was arranged with the "Educational Supervisor" of all hospitals regarding their institutional organization, departments, clini-cal capabilities, clinical qualifications, facilities and resources, rehabilitation services, performance improvement, continuing education, prevention, research and additional requirements for pediatric trauma patients. Relative frequencies and percentages were calculated and Student's t test was used to compare the mean values.Results: Forty-one hospitals had the average of 77.7 (50.7%) standards from 153 Arizona trauma center standards and these standards were present in 97.5 out of 153 (63.7%) in 17 general hospitals. Based on the subgroups of the standards, 64.8% items of hospital resources and capabilities were considered as a subgroup with the maximum criteria, and 17.7% items of research section as another subgroup with the minimum standards.Conclusions: On the basis of our findings, no hospital meet all the Arizona trauma center standards completely. The hospitals as trauma centers at different levels must be promoted to manage trauma patients desirably.

    The paper deals with an evolutionary integro-differential equation describing nonlinear waves. A particular choice of the kernel in the integral leads to well-known equations such as the Khokhlov-Zabolotskaya equation, the Kadomtsev-Petviashvili equation and others. Since the solutions of these equations describe many physical phenomena, the analysis of the general model studied in this paper is important. One of the methods for obtaining solutions of differential equations is provided by the Lie group analysis. However, this method is not applicable to integro-differential equations. Therefore, we discuss new approaches developed in modern group analysis and apply them to the general model considered in this paper. Reduced equations and exact solutions are also presented.

  3. Integrative analysis of multiple diverse omics datasets by sparse group multitask regression

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available A variety of high throughput genome-wide assays enable the exploration of genetic risk factors underlying complex traits. Although these studies have remarkable impact on identifying susceptible biomarkers, they suffer from issues such as limited sample size and low reproducibility. Combining individual studies of different genetic levels/platforms has the promise to improve the power and consistency of biomarker identification. In this paper, we propose a novel integrative method, namely sparse group multitask regression, for integrating diverse omics datasets, platforms and populations to identify risk genes/factors of complex diseases. This method combines multitask learning with sparse group regularization, which will: 1 treat the biomarker identification in each single study as a task and then combine them by multitask learning; 2 group variables from all studies for identifying significant genes; 3 enforce sparse constraint on groups of variables to overcome the ‘small sample, but large variables’ problem. We introduce two sparse group penalties: sparse group lasso and sparse group ridge in our multitask model, and provide an effective algorithm for each model. In addition, we propose a significance test for the identification of potential risk genes. Two simulation studies are performed to evaluate the performance of our integrative method by comparing it with conventional meta-analysis method. The results show that our sparse group multitask method outperforms meta-analysis method significantly. In an application to our osteoporosis studies, 7 genes are identified as significant genes by our method and are found to have significant effects in other three independent studies for validation. The most significant gene SOD2 has been identified in our previous osteoporosis study involving the same expression dataset. Several other genes such as TREML2, HTR1E and GLO1 are shown to be novel susceptible genes for osteoporosis, as confirmed

    Native Science Field Centers (NSFCs) were created to engage youth and adults in environmental science activities through the integration of traditional Native ways of knowing (understanding about the natural world based on centuries of observation including philosophy, worldview, cosmology, and belief systems of Indigenous peoples), Native languages, and Western science concepts. This paper focuses on the Blackfeet Native Science Field Center, the Lakota Native Science Field Center, and the Wind River Native Science Field Center. One of the long-term, overarching goals of these NSFCs was to stimulate the interest of Native American students in ways that encouraged them to pursue academic and career paths in science, technology, engineering, and mathematics (STEM) fields. A great deal can be learned from the experiences of the NSFCs in terms of effective educational strategies, as well as advantages and challenges in blending Native ways of knowing and Western scientific knowledge in an informal science education setting. Hopa Mountain—a Bozeman, Montana-based nonprofit—partnered with the Blackfeet Community College on the Blackfeet Reservation, Fremont County School District #21 on the Wind River Reservation, and Oglala Lakota College on the Pine Ridge Reservation to cooperatively establish the Native Science Field Centers. This paper presents a profile of each NSFC and highlights their program components and accomplishments.

  5. GALA: Group Analysis Leads to Accuracy, a novel approach for solving the inverse problem in exploratory analysis of group MEG recordings

    Directory of Open Access Journals (Sweden)

    Vladimir eKozunov

    2015-04-01

    Full Text Available Although MEG/EEG signals are highly variable between subjects, they allow characterizing systematic changes of cortical activity in both space and time. Traditionally a two-step procedure is used. The first step is a transition from sensor to source space by the means of solving an ill-posed inverse problem for each subject individually. The second is mapping of cortical regions consistently active across subjects. In practice the first step often leads to a set of active cortical regions whose location and timecourses display a great amount of interindividual variability hindering the subsequent group analysis.We propose Group Analysis Leads to Accuracy (GALA - a solution that combines the two steps into one. GALA takes advantage of individual variations of cortical geometry and sensor locations. It exploits the ensuing variability in electromagnetic forward model as a source of additional information. We assume that for different subjects functionally identical cortical regions are located in close proximity and partially overlap and their timecourses are correlated. This relaxed similarity constraint on the inverse solution can be expressed within a probabilistic framework, allowing for an iterative algorithm solving the inverse problem jointly for all subjects.A systematic simulation study showed that GALA, as compared with the standard min-norm approach, improves accuracy of true activity recovery, when accuracy is assessed both in terms of spatial proximity of the estimated and true activations and correct specification of spatial extent of the activated regions. This improvement obtained without using any noise normalization techniques for both solutions, preserved for a wide range of between-subject variations in both spatial and temporal features of regional activation. The corresponding activation timecourses exhibit significantly higher similarity across subjects. Similar results were obtained for a real MEG dataset of face

    The National Geophysical Data Center (NGDC) maintains a global historical event database of tsunamis, significant earthquakes, and significant volcanic eruptions. The database includes all tsunami events, regardless of intensity, as well as earthquakes and volcanic eruptions that caused fatalities, moderate damage, or generated a tsunami. Event date, time, location, magnitude of the phenomenon, and socio-economic information are included in the database. Analysis of the NGDC event database reveals that the 21st century began with earthquakes in Gujarat, India (magnitude 7.7, 2001) and Bam, Iran (magnitude 6.6, 2003) that killed over 20,000 and 31,000 people, respectively. These numbers were dwarfed by the numbers of earthquake deaths in Pakistan (magnitude 7.6, 2005-86,000 deaths), Wenchuan, China (magnitude 7.9, 2008-87,652 deaths), and Haiti (magnitude 7.0, 2010-222,000 deaths). The Haiti event also ranks among the top ten most fatal earthquakes. The 21st century has observed the most fatal tsunami in recorded history-the 2004 magnitude 9.1 Sumatra earthquake and tsunami that caused over 227,000 deaths and 10 billion damage in 14 countries. Six years later, the 2011 Tohoku, Japan earthquake and tsunami, although not the most fatal (15,000 deaths and 5,000 missing), could cost Japan's government in excess of 300 billion-the most expensive tsunami in history. Volcanic eruptions can cause disruptions and economic impact to the airline industry, but due to their remote locations, fatalities and direct economic effects are uncommon. Despite this fact, the second most expensive eruption in recorded history occurred in the 21st century-the 2010 Merapi, Indonesia volcanic eruption that resulted in 324 deaths, 427 injuries, and $600 million in damage. NGDC integrates all natural hazard event datasets into one search interface. Users can find fatal tsunamis generated by earthquakes or volcanic eruptions. The user can then link to information about the related runup

  8. Group theoretical analysis of the H3+ +H2 ↔ H5+ reaction

    Science.gov (United States)

    Lin, Zhou

    2016-06-01

    The H3+ +H2 →H2 + H3+ proton transfer reaction is complicated due to the proton scrambling from the large amplitude motions in the H5+ intermediate. In order to understand this reaction, high-resolution spectroscopic studies are necessary for the reactants/products and the intermediate, and the group theoretical analysis is an essential aspect in the prediction and interpretation of these spectra. With five indistinguishable protons, H5+ is characterized using the G240 complete nuclear permutation-inversion (CNPI) group. For most of the configurations sampled by the reaction path, the feasible permutations depend on the distance between the H3+ and H2 fragments. Subgroups of G240 can be used to describe these feasible permutations. Specifically, we consider two limits of the molecular configurations. The equilibrium structure of H5+ , i.e., [H2 -H -H2 ]+, can be described using the G16 molecular symmetry group, while the dissociation products, i.e., H3+ ⋯H2 , require the G24 molecular symmetry group. In the present study, a group theoretical analysis is performed for both limits, providing the symmetries for the nuclear spins and rovibrational wave functions. Also, spectroscopic properties for [H2 -H -H2 ]+, particularly rovibrational couplings and electric dipole selection rules, as well as correlations of energy levels between [H2 -H -H2 ]+ and H3+ ⋯H2 , are obtained.

    This technical memorandum presents a summary by the Electromagnetics and Aerospace Environments Branch at the Marshall Space Flight Center of lightning characteristics and lightning criteria for the protection of aerospace vehicles. Probability estimates are included for certain lightning strikes (peak currents of 200, 100, and 50 kA) applicable to the National Aeronautics and Space Administration Space Shuttle at the Kennedy Space Center, Florida, during rollout, on-pad, and boost/launch phases. Results of an extensive literature search to compile information on this subject are presented in order to answer key questions posed by the Space Shuttle Program Office at the Johnson Space Center concerning peak lightning current probabilities if a vehicle is hit by a lightning cloud-to-ground stroke. Vehicle-triggered lightning probability estimates for the aforementioned peak currents are still being worked. Section 4.5, however, does provide some insight on estimating these same peaks.

  10. Assessing students' genre knowledge in an engineering writing center: An analysis of sophomore lab reports in electrical and computer engineering

    Walker, Kristin Wilds Davidson

    As discipline-specific writing centers continue to increase in number, writing center consultants must determine ways to help their clients acquire discipline-specific and course-specific literacy. One way to achieve this goal is through genre analysis. This study focuses on the genre of EECE 201 (Tools and Techniques for Electrical and Computer Engineers) lab reports and strategies writing center consultants can implement to teach students communication skills necessary for discipline-specific literacy. Beginning with a discussion of the Electrical and Computer Engineering (ECE) Writing Center's history, the methodological foundations of this study, and an historical overview of genre theory from classical times to the present, this study surveys the history and debates surrounding teaching genres to students. The role of assessment in analyzing and teaching genre is discussed as well, with application specifically to the sophomore-level EECE 201 course within ECE at the University of South Carolina. The study itself consists of analyzing four students' lab reports written for the EECE 201 course. Using a list of eleven characteristics developed with experienced communicators within this discipline, I analyzed each report (there is a total of 14), determining to what extent the characteristics appeared in the reports. At the end of each student's analysis, a table summarizes the information gathered from the reports, and overall conclusions are drawn for each student. The end of the study chapter presents generic writing trends exhibited by the students during the semester, such as inability to show evidence of inductive/deductive reasoning and difficulties with conceptualizing audience and applying formatting skills. The study concludes by recommending strategies that ECE Writing Center consultants can implement to help the sophomore students acquire discipline-specific knowledge. Going beyond the ECE Writing Center's context, however, the study also suggests

    In the present study a series of 45 metabolite standards belonging to four chemically similar metabolite classes (sugars, amino acids, nucleosides and nucleobases, and amines) was subjected to LC analysis on three HILIC columns under 21 different gradient conditions with the aim to explore whether the retention properties of these analytes are determined from the chemical group they belong. Two multivariate techniques, principal component analysis (PCA) and discriminant analysis (DA), were used for statistical evaluation of the chromatographic data and extraction similarities between chemically related compounds. The total variance explained by the first two principal components of PCA was found to be about 98%, whereas both statistical analyses indicated that all analytes are successfully grouped in four clusters of chemical structure based on the retention obtained in four or at least three chromatographic runs, which, however should be performed on two different HILIC columns. Moreover, leave-one-out cross-validation of the above retention data set showed that the chemical group in which an analyte belongs can be 95.6% correctly predicted when the analyte is subjected to LC analysis under the same four or three experimental conditions as the all set of analytes was run beforehand. That, in turn, may assist with disambiguation of analyte identification in complex biological extracts.

    Clostridium botulinum is a genetically diverse Gram-positive bacterium producing extremely potent neurotoxins (botulinum neurotoxins A through G [BoNT/A-G]). The complete genome sequences of three strains harboring only the BoNT/A1 nucleotide sequence are publicly available. Although these strains contain a toxin cluster (HA(+) OrfX(-)) associated with hemagglutinin genes, little is known about the genomes of subtype A1 strains (termed HA(-) OrfX(+)) that lack hemagglutinin genes in the toxin gene cluster. We sequenced the genomes of three BoNT/A1-producing C. botulinum strains: two strains with the HA(+) OrfX(-) cluster (69A and 32A) and one strain with the HA(-) OrfX(+) cluster (CDC297). Whole-genome phylogenic single-nucleotide-polymorphism (SNP) analysis of these strains along with other publicly available C. botulinum group I strains revealed five distinct lineages. Strains 69A and 32A clustered with the C. botulinum type A1 Hall group, and strain CDC297 clustered with the C. botulinum type Ba4 strain 657. This study reports the use of whole-genome SNP sequence analysis for discrimination of C. botulinum group I strains and demonstrates the utility of this analysis in quickly differentiating C. botulinum strains harboring identical toxin gene subtypes. This analysis further supports previous work showing that strains CDC297 and 657 likely evolved from a common ancestor and independently acquired separate BoNT/A1 toxin gene clusters at distinct genomic locations.

    Regulatory changes proposed by the US Department of Agriculture in 1994 promised to bring progressive changes to school meals. However, lobbying by interest groups resulted in substantial changes to the final rule. This analysis retrospectively examines the federal school meals policy-making process during 1992 to 1996. Key questions address why the policy changed and what the role of interest groups was in affecting the shape, pace, and direction of the policy. The study provides suggestions for using the experiences of 1992 to 1996 to guide future advocacy efforts and for adapting the approach for application to other food and nutrition policies.

    Full Text Available BACKGROUND: At present Diabetes Mellitus is a global phenomenon with the disease topping the list, comprising of about 32 million cases , India is in the forefront with 30% of the cases . The disease affects multiple organs and is a leading cause of much morbidity and mortality. Since it is a multi - factorial disease a major step would be to identify different associated factors, for an early diagnosis and prompt treatment. The ABO blood groups are often associated with several diseases, with one blood group more often seen with the patients of a particular disease. Our study will help to determine the frequency and distribution of blood groups in correlation with Diabetes Mellitus. MATERIAL & METHODS: This study was conducted in the Gandhi Medical College, Secunderabad, during a two year period. A random study involving every third diabetic patient was chosen and their blood group was determined. A total of 3 00 patients were selected with 150 male and 150 female patients. Another 300 volunteers who were not diabetics were chosen as controls and their blood groups were also determined. A pro - forma was given to both diabetics and controls which included the following variables : 1 . Demographic data 2. Blood grouping 3. Fasting and post prandial blood sugar. Following this, blood groups of both cohorts and controls were determined by antigen antibody agglutination method. Data analysis was do ne after data was entered into excel sheet and double checked for errors using SPSS Software RESULTS: Our a nalysis showed that O group was significantly more among diabetic patients when all patients were compared to control . ² there was a preponderance of blood group O among female diabetics and B among male diabetics. CONCLUSION: ABO blood groups have been determined in 300 diabetic patients and compared with the controls comprising of a series of 300 voluntary blood donors. When the results were analysed on the basis of sex, there was preponderance

    Full Text Available Abstract Background Group B Streptococcus (GBS serotype (Ia, Ib, II-IX correlates with pathogen virulence and clinical prognosis. Epidemiological studies of seroprevalence are an important metric for determining the proportion of serotypes in a given population. The purpose of this study was to evaluate the prevalence of individual GBS serotypes at Madigan Healthcare System (Madigan, the largest military tertiary healthcare facility in the Pacific Northwestern United States, and to compare seroprevalences with international locations. Methods To determine serotype distribution at Madigan, we obtained GBS isolates from standard-of-care anogenital swabs from 207 women of indeterminate gravidity between ages 18-40 during a five month interval. Serotype was determined using a recently described molecular method of polymerase chain reaction by capsular polysaccharide synthesis (cps genes associated with pathogen virulence. Results Serotypes Ia, III, and V were the most prevalent (28%, 27%, and 17%, respectively. A systematic review of global GBS seroprevalence, meta-analysis, and statistical comparison revealed strikingly similar serodistibution at Madigan relative to civilian-sector populations in Canada and the United States. Serotype Ia was the only serotype consistently higher in North American populations relative to other geographic regions (p Conclusion This study establishes PCR-based serotyping as a viable strategy for GBS epidemiological surveillance. Our results suggest that GBS seroprevalence remains stable in North America over the past two decades.

    The Chandra Galactic Center Survey detected ~ 800 X-ray point-like sources in the 2°× 0.8° sky region around the Galactic Center. We study the spatial and luminosity distributions of these sources according to their spectral properties. Fourteen bright sources detected are used to fit jointly an absorbed power-law model, from which the power-law photon index is determined to be ~2.5. Assuming that all other sources have the same power-law form, the relation between hardness ratio and HI column density NH is used to estimate the NH values for all sources. Monte Carlo simulations show that these sources are more likely concentrated in the Galactic center region, rather than distributed throughout the Galactic disk. We also find that the luminosities of the sources are positively correlated with their HI column densities, i.e., a more luminous source has a higher HI column density. From this relation, we suggest that the X-ray luminosity comes from the interaction between an isolated old neutron star and interstellar medium (mainly dense molecular clouds). Using the standard Bondi accretion theory and the statistical information of molecular clouds in the Galactic center, we confirm this positive correlation and calculate the luminosity range in this scenario,which is consistent with the observation (1032 - 1035 erg s-1).

    Poison centers advance knowledge in the field of toxicology through publication in peer-review journals. This investigation describes the pattern of poison center-related publications. Cases were poison center-related research published in peer-review journals during 1995-2014. These were identified through searching the PubMed database, reviewing the tables of contents of selected toxicology journals, and reviewing abstracts of various national and international meetings. The following variables for each publication were identified: year of publication, journal, type of publication (meeting abstract vs. other, i.e. full article or letter to the editor), and the country(ies) of the poison center(s) included in the research. Of the 3147 total publications, 62.1% were meeting abstracts. There were 263 publications in 1995-1999, 536 in 2000-2004, 999 in 2005-2009, and 1349 in 2010-2014. The publications were in 234 different journals. The journals in which the highest number of research was published were Clinical Toxicology (69.7%), Journal of Medical Toxicology (2.2%), and Veterinary and Human Toxicology (2.1%). The research was reported from 62 different countries. The countries with the highest number of publications were the United States (67.9%), United Kingdom (6.5%), Germany (3.9%), France (2.5%), and Italy (2.4%). The number of publications increased greatly over the 20 years. Although the publications were in a large number of journals, a high proportion of the publications were in one journal. While the research came from a large number of countries, the preponderance came from the United States.

    Heliotropium bacciferum is paramount in medicinal perspective and belongs to Boraginaceae family. The crude and numerous fractions of leaves, stem, and roots of the plant were investigated for phytochemical analysis and DPPH radical scavenging activity. Phytochemical analysis of crude and fractions of the plant revealed the presence of alkaloids, saponins, tannins, steroids, terpenoids, flavonoids, glycosides, and phenols. The antioxidant (free radical scavenging) activity of various extracts of the Heliotropium bacciferum was resolute against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical with the avail of UV spectrophotometer at 517 nm. The stock solution (1000 mg/mL) and then several dilutions (50, 100, 150, 200, and 250 mg/mL) of the crude and fractions were prepared. Ascorbic acid was used as a standard. The plant leaves (52.59 ± 0.84 to 90.74 ± 1.00), stem (50.19 ± 0.92 to 89.42 ± 1.10), and roots extracts (49.19 ± 0.52 to 90.01 ± 1.02) divulged magnificent antioxidant activities. For the ascertainment of the fatty acid constituents a gas chromatograph hyphenated to mass spectrometer was used. The essential fatty acids for growth maintenance such as linoleic acid (65.70%), eicosadienoic acid (15.12%), oleic acid (8.72%), and palmitic acid (8.14%) were found in high percentage. The infrared spectra of all extracts of the plant were recorded by IR Prestige-21 FTIR model.

    2013-01-01

    This is a summary of the methods we used to analyse the first IPTA Mock Data Challenge (MDC), and the obtained results. We have used a Bayesian analysis in the time domain, accelerated using the recently developed ABC-method which consists of a form of lossy linear data compression. The TOAs were first processed with Tempo2, where the design matrix was extracted for use in a subsequent Bayesian analysis. We used different noise models to analyse the datasets: no red noise, red noise the same for all pulsars, and individual red noise per pulsar. We sampled from the likelihood with four different samplers: "emcee", "t-walk", "Metropolis-Hastings", and "pyMultiNest". All but emcee agreed on the final result, with emcee failing due to artefacts of the high-dimensionality of the problem. An interesting issue we ran into was that the prior of all the 36 (red) noise amplitudes strongly affects the results. A flat prior in the noise amplitude biases the inferred GWB amplitude, whereas a flat prior in log-amplitude se...

    Little research exists regarding the use of social networking sites, like Facebook, for improving patient well-being. The aim of this study was to evaluate a private Facebook group established for members of an HIV clinic's young adult program. This study employed directed content analysis to examine the types and frequencies of interactions observable in the 3,838 posts and comments that appeared on the Facebook group page between March 1, 2011 and July 1, 2012. Analysis revealed that a large percentage (41.7 %) of the content was classified as "administrative/engagement in group" and functioned to enhance the operations of the program as a whole. Additionally, positive interactions were frequently observed, especially socializing (24.8 %), banter (20.2 %), and offers of social support (15.1 %). Emotional support was the most frequent type of support requested, while esteem support was the most commonly provided form of support. The results of this study demonstrate that a Facebook group can be a means of providing patients with social support and positive social interaction and can improve services for young adults with HIV.

    The present study describes the development of a new analytical technique for the functional group determination of the carboxylic moiety using atmospheric pressure chemical ionization-mass spectrometry (APCI-MS/MS) operated in the constant neutral loss scanning (CNLS) mode. Carboxylic groups were first derivatized into their corresponding methyl esters by reacting with BF{sub 3}/methanol mix and the reaction mixture was then directly injected into the APCI chamber. The loss of methanol (m/z = 32 amu) resulting from the fragmentation of the protonated methyl esters was then monitored. Applying this method together with a statistical approach to reference mixtures containing 31 different carboxylic acids at randomly calculated concentrations demonstrated its suitability for quantitative functional group measurements with relative standard deviations below 15% and a detection limit of 0.005 mmol L{sup -1}. Its applicability to environmental matrices was also shown through the determination of carboxylic acid concentrations inside atmospheric aerosol samples. To the best of our knowledge, it is the first time that the tandem mass spectrometry was successfully applied to functional group analysis, offering great perspectives in the characterization of complex mixtures which are prevailing in the field of environmental analysis as well as in the understanding of the chemical processes occurring in these matrices.

    Argentinean Patagonia is inhabited by people that live principally in urban areas and by small isolated groups of individuals that belong to indigenous aboriginal groups; this territory exhibits the lowest population density of the country. Mapuche and Tehuelche (Mapudungun linguistic branch), are the only extant Native American groups that inhabit the Argentinean Patagonian provinces of Río Negro and Chubut. Fifteen autosomal STRs, 17 Y-STRs, mtDNA full length control region sequence and two sets of Y and mtDNA-coding region SNPs were analyzed in a set of 434 unrelated individuals. The sample set included two aboriginal groups, a group of individuals whose family name included Native American linguistic root and urban samples from Chubut, Río Negro and Buenos Aires provinces of Argentina. Specific Y Amerindian haplogroup Q1 was found in 87.5% in Mapuche and 58.82% in Tehuelche, while the Amerindian mtDNA haplogroups were present in all the aboriginal sample contributors investigated. Admixture analysis performed by means of autosomal and Y-STRs showed the highest degree of admixture in individuals carrying Mapuche surnames, followed by urban populations, and finally by isolated Native American populations as less degree of admixture. The study provided novel genetic information about the Mapuche and Tehuelche people and allowed us to establish a genetic correlation among individuals with Mapudungun surnames that demonstrates not only a linguistic but also a genetic relationship to the isolated aboriginal communities, representing a suitable proxy indicator for assessing genealogical background.

    Full Text Available In recent years, there have been requirments for a transport environment that will foster the development of safe, comfortable townships. The study of urban activities amid an aging society and effective use of public transport modes in addressing environmental problems have become particularly important issues. This study analyzes travel behaviour patterns of varying age groups using urban railways in order to examine the relationship between urban public transport use and urban activities. specifically, it analyzes the composition of urban activity and travel behaviour patterns among urban railway users in the Keihanshin (Kyoto-Osaka-Kobe metropolitan area. This paper looks at urban activities within aging societies and identifies the differences in travel behaviour of railway users by separating them into young, middle aged and senior citizen age groups. Analysis makes particular use of the Railway station Database, which is a compilation of existing studies into attributes of railway stations and their surroundings, and results of person trip surveys. Rail use behaviour characteristics have been sorted by age group because mobility via urban railway systems is varied by age group. As a result, differences in railway usage patterns (travel objectives, distance and time, and number of transfers, etc. have been identified and so too have differences in urban activity patterns related to free activities (shopping, recreation. Furthermore, the study developed a travel behaviour pattern estimation model which is capable of categorizing specific transport behaviour patterns and estimating rail users and transport behaviour patterns from the relationship with areas surrounding railway stations to ensure future mobility by public transport for older age groups. The results make it possible to put forward proposals for urban rail services that will facilitate urban activities for the different age groups. Eventually, it will be possible to understand

    Bacteria closely related to Bacillus pumilus cannot be distinguished from such other species as B. safensis, B. stratosphericus, B. altitudinis and B. aerophilus simply by 16S rRNA gene sequence. In this report, 76 marine strains were subjected to phylogenetic analysis based on 7 housekeeping genes to understand the phylogeny and biogeography in comparison with other origins. A phylogenetic tree based on the 7 housekeeping genes concatenated in the order of gyrB-rpoB-pycA-pyrE-mutL-aroE-trpB was constructed and compared with trees based on the single genes. All these trees exhibited a similar topology structure with small variations. Our 79 strains were divided into 6 groups from A to F; Group A was the largest and contained 49 strains close to B. altitudinis. Additional two large groups were presented by B. safensis and B. pumilus respectively. Among the housekeeping genes, gyrB and pyrE showed comparatively better resolution power and may serve as molecular markers to distinguish these closely related strains. Furthermore, a recombinant phylogenetic tree based on the gyrB gene and containing 73 terrestrial and our isolates was constructed to detect the relationship between marine and other sources. The tree clearly showed that the bacteria of marine origin were clustered together in all the large groups. In contrast, the cluster belonging to B. safensis was mainly composed of bacteria of terrestrial origin. Interestingly, nearly all the marine isolates were at the top of the tree, indicating the possibility of the recent divergence of this bacterial group in marine environments. We conclude that B. altitudinis bacteria are the most widely spread of the B. pumilus group in marine environments. In summary, this report provides the first evidence regarding the systematic evolution of this bacterial group, and knowledge of their phylogenetic diversity will help in the understanding of their ecological role and distribution in marine environments.

    Shape analysis has become of increasing interest to the neuroimaging community due to its potential to precisely locate morphological changes between healthy and pathological structures. This manuscript presents a comprehensive set of tools for the computation of 3D structural statistical shape analysis. It has been applied in several studies on brain morphometry, but can potentially be employed in other 3D shape problems. Its main limitations is the necessity of spherical topology. The input of the proposed shape analysis is a set of binary segmentation of a single brain structure, such as the hippocampus or caudate. These segmentations are converted into a corresponding spherical harmonic description (SPHARM), which is then sampled into a triangulated surfaces (SPHARM-PDM). After alignment, differences between groups of surfaces are computed using the Hotelling T2 two sample metric. Statistical p-values, both raw and corrected for multiple comparisons, result in significance maps. Additional visualization of the group tests are provided via mean difference magnitude and vector maps, as well as maps of the group covariance information. The correction for multiple comparisons is performed via two separate methods that each have a distinct view of the problem. The first one aims to control the family-wise error rate (FWER) or false-positives via the extrema histogram of non-parametric permutations. The second method controls the false discovery rate and results in a less conservative estimate of the false-negatives. Prior versions of this shape analysis framework have been applied already to clinical studies on hippocampus and lateral ventricle shape in adult schizophrenics. The novelty of this submission is the use of the Hotelling T2 two-sample group difference metric for the computation of a template free statistical shape analysis. Template free group testing allowed this framework to become independent of any template choice, as well as it improved the

    The Coastal Fishing Port (CFP) Tegalsari is one of the largest center of the fishery industries in Central Java Indonesia. In addition to producing fish-based products such as fish fillets, salted fish and fish meal are distributed to most major cities in Indonesia, but also generate waste and wastewater which potentially disrupt the environment. The purpose of this study describe the perception of the public about the negative impact of the activities in center fishery processing industry. The research method uses qualitative research design with the population living around the center of the fishing industry, with samples taken by purposive sampling numbered 30 people and 3 location sample to know concentration of ammoniac and hydrogen Sulfide. Data research in 2016 was processed using statistical methods. The results of research showed very significant, 80% of respondents who said the fishing activities causing nuisance odor. The remaining 20% stated that the odor nuisance almost imperceptibly. The nuisance of odor are perceived by 53% of respondents for a full day. There are 70% of respondents living around the center of the fishing industry who lived more than seven years, and the remaining 30% of respondents who lived less than 7 years. Conclusion respondent who live more than seven years and said there was no odor nuisance around 57%, are more than 50% of the respondents. The odor of the most influential parameter on the fishing industry is an element of ammoniac (NH3) instead of Hydrogen Sulfide (H2S), because the value at these three locations for Hydrogen Sulfide measurement results show the same number that is equal to 0.001 g/m3. While ammoniac levels at most locations smelled according to perceptions of examiners showed the highest scores, while the zone that did not feel the smell indicates a low value, the test results showed a clear level of distinction. So the need to manage the environment at the center of the fishing industry with a approach of

    The Fe3+ center in ferroelectric PbTiO3 together with an oxygen vacancy forms a charged defect associate, oriented along the crystallographic c axis. Its microscopic structure has been analyzed in detail comparing results from a semiempirical Newman superposition model analysis based on fine-structure data and from calculations using density functional theory. Both methods give evidence for a substitution of Fe3+ for Ti4+ as an acceptor center. The position of the iron ion in the ferroelectric phase is found to be similar to the B site in the paraelectric phase. Partial charge compensation is locally provided by a directly coordinated oxygen vacancy. Using high-resolution synchrotron powder diffraction, it was verified that lead titanate remains tetragonal down to 12K , exhibiting a c/a ratio of 1.0721.

    Full Text Available The policy of continuing healthcare education (CHE aims to develop healthcare workers. With the objective of analyzing the process of implementing and developing the policy in Paraná, a qualitative study involving the six regions of this state is being concluded. This paper relates to the results from the northern region, focusing on the "experiencing CHE" category. In December 2006, two focus groups were conducted involving representatives from management, training, attendance and participation. The data underwent thematic content analysis. The first CHE encounters aroused feelings of mistrust and resistance, and the center was understood as a means of enabling courses and funding sources. There was a diversity of interests and little negotiating capacity. During the process, the study participants began to talk, reflect and participate. Their teamwork was a positive experience. This experience allowed them to recognize the power of CHE for linking and mobilizing different players.

    Full Text Available Ukraine is a leader in Europe in the prevalence of HIV infection. There are up to 270 thousand people, who are living with HIV. Since 1987, in Ukraine, 33,149 HIV-infected people died. During the first six months of 2013, of all the dead, who were suffering from HIV and in need of antiretroviral treatment (ART at the time of death, 41% received treatment and only 5.7% received ART for more than one year. Specialists of Kiev Regional AIDS Center analyzed mortality among the patients of the centre, in order to determine the most frequent cause of death, set the group most at risk and to develop effective measures to reduce mortality among HIV-infected patients. In Kiev AIDS Center, 10,000 people are under medical observation and 4004 of them are taking ART. During 2013, 305 persons died: 217 were women and 88 were men which included 3 children under 14 years. Most of the dead – 272 (89% were aged 25–49. Among the total number of the dead, 125 people (41% were receiving ART, 53 of them (17% were receiving ART for at least one year and 39 of them (13% were receiving ART for less than one month. Hundred and fifty-eight people (52% required ART and 22 (7% did not need therapy. Hundred and ninety-two patients (63% were in four clinical stage of HIV infection. Hundred and ten of them had HIV+TB co-infection. Twenty patients died due to TB and 12 patients died due to hepatitis b virus/hepatitis c virus (HBV/HCV. Among these patients, 87 people (39% were taking ART and 136 persons (61% were in need of ART, but did not get it. Nineteen patients were diagnosed with cancer. Sixteen patients, who were co-infected HIV+TB had a CD4 cell count of more than 300. Based on this analysis, we can conclude that the main causes of high mortality among HIV-infected patients in 2013 were late diagnosis of HIV, besides a large number (52% of patients, who were in need of ART did not take it. A large number (40% among those who died were patients co-infected with HIV

    Purpose To define characteristics, treatment response, and outcomes of men with brain metastases (BM) from germ cell tumors (GCT). Patients and Methods Data from 523 men with BM from GCT were collected retrospectively from 46 centers in 13 countries by using standardized questionnaires. Clinical features were correlated with overall survival (OS) as the primary end point. Results BM were present at initial diagnosis in 228 men (group A) and at relapse in 295 men (group B). OS at 3 years (3-year OS) was superior in group A versus group B (48% v 27%; P < .001). Multiple BM and the presence of liver or bone metastasis were independent adverse prognostic factors in both groups; primary mediastinal nonseminoma (group A) and elevations of α-fetoprotein of 100 ng/mL or greater or of human chorionic gonadotropin of 5,000 U/L or greater (group B) were additional independent adverse prognostic factors. Depending on these factors, the 3-year OS ranged from 0% to 70% in group A and from 6% to 52% in group B. In group A, 99% of patients received chemotherapy; multimodality treatment or high-dose chemotherapy was not associated with statistically improved survival in multivariable analysis. In group B, only 54% of patients received chemotherapy; multimodality treatment was associated with improved survival compared with single-modality therapy (hazard ratio, 0.51; 95% CI, 0.36 to 0.73; P < .001), as was high-dose compared with conventional-dose chemotherapy (hazard ratio, 0.41; 95% CI, 0.24 to 0.70; P = .001). Conclusion Men with BM from GCT have poor OS, particularly if additional risk factors are present. High-dose chemotherapy and multimodality treatment seemed to improve survival probabilities in men with BM at relapse. PMID:26460295

    Hypopituitarism in adult life is commonly acquired and the main causes are known as pituitary tumors and/or their treatments. Since there are new insights into the etiology of hypopituitarism and presence of differences in various populations, more studies regarding causes of hypopituitarism are needed to be done in different ethnic groups with sufficient number of patients. Therefore, we performed a multi-center database study in Turkish population investigating the etiology of hypopituitarism in 773 patients in tertiary care institutions. The study was designed and coordinated by the Pituitary Study Group of SEMT (The Society of Endocrinology and Metabolism of Turkey). Nineteen tertiary reference centers (14 university hospitals and 5 training hospitals) from the different regions of Turkey participated in the study. It is a cross-sectional database study, and the data were recorded for 18 months. We mainly classified the causes of hypopituitarism as pituitary tumors (due to direct effects of the pituitary tumors and/or their treatments), extra-pituitary tumors and non-tumoral causes. Mean age of 773 patients (49.8 % male, 50.2 % female) was 43.9 ± 16.1 years (range 16-84 years). The most common etiology of pituitary dysfunction was due to non-tumoral causes (49.2 %) among all patients. However, when we analyze the causes according to gender, the most common etiology in males was pituitary tumors, but the most common etiology in females was non-tumoral causes. According to the subgroup analysis of the causes of hypopituitarism in all patients, the most common four causes of hypopituitarism which have frequencies over 10 % were as follows: non-secretory pituitary adenomas, Sheehan's syndrome, lactotroph adenomas and idiopathic. With regard to the type of hormonal deficiencies; FSH/LH deficiency was the most common hormonal deficit (84.9 % of the patients). In 33.8 % of the patients, 4 anterior pituitary hormone deficiencies (FSH/LH, ACTH, TSH, and GH) were

    A new 19 X- short tandem repeat (STR) multiplex PCR system has recently been developed, though its applicability in forensic studies has not been thoroughly assessed. In this study, 932 unrelated individuals from four Chinese ethnic groups (Han, Tibet, Uighur and Hui) were successfully genotyped using this new multiplex PCR system. Our results showed significant linkage disequilibrium between markers DXS10103 and DXS10101 in all four ethnic groups; markers DXS10159 and DXS10162, DXS6809 and DXS6789, and HPRTB and DXS10101 in Tibetan populations; and markers DXS10074 and DXS10075 in Uighur populations. The combined powers of discrimination in males and females were calculated according to haplotype frequencies from allele distributions rather than haplotype counts in the relevant population and were high in four ethnic groups. The cumulative powers of discrimination of the tested X-STR loci were 1.000000000000000 and 0.999999999997940 in females and males, respectively. All 19 X-STR loci are highly polymorphic. The highest Reynolds genetic distances were observed for the Tibet-Uighur pairwise comparisons. This study represents an extensive report on X-STR marker variation in minor Chinese populations and a comprehensive analysis of the diversity of these 19 X STR markers in four Chinese ethnic groups.

    The interaction between pile and soft soil of the passive pile group subjected to soil movement was analyzed with three-dimensional finite element model by using ANSYS software. The soil was assumed to be elastic-plastic complying with the Drucker-Prager yield criterion in the analysis. The large displacement of soil was considered and contact elements were used to evaluate the interaction between pile and soil. The influences of soil depth of layer and number of piles on the lateral pressure of the pile were investigated, and the lateral pressure distributions on the (2×1) pile group and on the (2×2) pile group were compared. The results show that the adjacent surcharge may result in significant lateral movement of the soft soil and cousiderable pressure on the pile. The pressure acting on the row near the surcharge is higher than that on the other row, due to the "barrier" and arching effects in pile groups. The passive load and its distribution should be taken into account in the design of the passive piles.

    Full Text Available Understanding the organizational architecture of human brain function and its alteration patterns in diseased brains such as Autism Spectrum Disorder (ASD patients are of great interests. In-vivo functional magnetic resonance imaging (fMRI offers a unique window to investigate the mechanism of brain function and to identify functional network components of the human brain. Previously, we have shown that multiple concurrent functional networks can be derived from fMRI signals using whole-brain sparse representation. Yet it is still an open question to derive group-wise consistent networks featured in ASD patients and controls. Here we proposed an effective volumetric network descriptor, named connectivity map, to compactly describe spatial patterns of brain network maps and implemented a fast framework in Apache Spark environment that can effectively identify group-wise consistent networks in big fMRI dataset. Our experiment results identified 144 group-wisely common intrinsic connectivity networks (ICNs shared between ASD patients and healthy control subjects, where some ICNs are substantially different between the two groups. Moreover, further analysis on the functional connectivity and spatial overlap between these 144 common ICNs reveals connectomics signatures characterizing ASD patients and controls. In particular, the computing time of our Spark-enabled functional connectomics framework is significantly reduced from 240 hours (C++ code, single core to 20 hours, exhibiting a great potential to handle fMRI big data in the future.

    Independent component analysis (ICA) is widely used in the field of functional neuroimaging to decompose data into spatio-temporal patterns of co-activation. In particular, ICA has found wide usage in the analysis of resting state fMRI (rs-fMRI) data. Recently, a number of large-scale data sets have become publicly available that consist of rs-fMRI scans from thousands of subjects. As a result, efficient ICA algorithms that scale well to the increased number of subjects are required. To address this problem, we propose a two-stage likelihood-based algorithm for performing group ICA, which we denote Parallel Group Independent Component Analysis (PGICA). By utilizing the sequential nature of the algorithm and parallel computing techniques, we are able to efficiently analyze data sets from large numbers of subjects. We illustrate the efficacy of PGICA, which has been implemented in R and is freely available through the Comprehensive R Archive Network, through simulation studies and application to rs-fMRI data from two large multi-subject data sets, consisting of 301 and 779 subjects respectively.

    Custodians represent one of the largest occupational groups using cleaning agents, and yet their voices are infrequently heard in relation to the introduction of "green" cleaners and the laws regarding environmentally preferable products (EPP). This study reflects worker voices on use and effectiveness of chemicals, as well as incentives and obstacles for green cleaning programs. Sixty-four custodians and staff participated in 10 focus groups. Data were entered into Atlas Ti and the constant comparative method of qualitative data analysis was used to identify themes. Themes included satisfaction in a "well-done" job, more effort required for job, lack of involvement in EPP selection process, EPP's ease of use for workers with English as a Second Language (ESL), misuse of disinfectants, health complaints, and need for training. This study shows that custodians have a voice, and that improved communication and feedback among all the stakeholders are needed to make the transition to green cleaning more effective.

    Osteoporotic fractures present a significant social and economic burden, which is set to rise commensurately with the aging population. Greater understanding of the physicochemical differences between osteoporotic and normal conditions will facilitate the development of diagnostic technologies with increased performance and treatments with increased efficacy. Using coherent X-ray scattering we have evaluated a population of 108 ex vivo human bone samples comprised of non-fracture and fracture groups. Principal component fed linear discriminant analysis was used to develop a classification model to discern each condition resulting in a sensitivity and specificity of 93% and 91%, respectively. Evaluating the coherent X-ray scatter differences from each condition supports the hypothesis that a causal physicochemical change has occurred in the fracture group. This work is a critical step along the path towards developing an in vivo diagnostic tool for fracture risk prediction.

    This study investigated the process of resolving painful emotional experience during psychodrama group therapy, by examining significant therapeutic events within seven psychodrama enactments. A comprehensive process analysis of four resolved and three not-resolved cases identified five meta-processes which were linked to in-session resolution. One was a readiness to engage in the therapeutic process, which was influenced by client characteristics and the client's experience of the group; and four were therapeutic events: (1) re-experiencing with insight; (2) activating resourcefulness; (3) social atom repair with emotional release; and (4) integration. A corrective interpersonal experience (social atom repair) healed the sense of fragmentation and interpersonal disconnection associated with unresolved emotional pain, and emotional release was therapeutically helpful when located within the enactment of this new role relationship. Protagonists who experienced resolution reported important improvements in interpersonal functioning and sense of self which they attributed to this experience.

    Full Text Available Given the start of new peace talks between the FARC guerrillas and the Colom-bian government, it is crucial to understand the role of Colombian journalists in reporting peace and war.This article presents an analysis on the National Press coverage of the demobilizations of a paramilitary group (Bloque Cacique Nutibara and a section of the FARC guerrillas (BloqueCacicaGaitana within a frame that reflects over the ethical practice of journalism in the context of war. The results are consistent with literature arguing that ethical codes are not documents dictating how journalists should do their job, but rather they repre-sent political acts of communication which allow journalists to reclaim their prof-fessional independence from sources and defend themselves from threats. The paper also discusses the apparent tension between journalism ethics, and the barriers imposed by the media´s informational needs and the strategic military aims of armed groups.

    Our purpose was to investigate health care professionals' beliefs about effective teamwork in medical emergencies based on their experiences. We used framework analysis of interprofessional focus groups in four secondary and tertiary maternity units. The participants were randomly selected senior and junior doctors, senior and junior midwives, and health care assistants, in five groups of 5 to 7 participants each. We found that optimal teamwork was perceived to be dependent on good leadership and availability of experienced staff. The participants described a good leader as one who verbally declares being the leader, communicates clear objectives, and allocates critical tasks, including communication with patients or their family, to suitable individual members. We triangulated the results with evidence from simulation to identify convergent findings and issues requiring further research. The findings will inform the development of teaching programs for medical teams who manage emergencies to improve patient safety and experience.

    2008-01-01

    Flow logs from 24 test wells were analyzed as part of the hydraulic characterization of the metamorphosed and fractured carbonate bedrock at the Indian Point Energy Center in Buchanan, New York. The flow logs were analyzed along with caliper, optical- and acoustic-televiewer, and fluid-resistivity and temperature logs to determine the character and distribution of fracture-flow zones and estimate their transmissivities and hydraulic heads. Many flow zones were associated with subhorizontal to shallow-dipping fractured zones, southeast-dipping bedding fractures, northwest-dipping conjugate fractures, or combinations of bedding and conjugate fractures. Flow-log analysis generally provided reasonable first-order estimates of flow-zone transmissivity and head differences compared with the results of conventional hydraulic-test analysis and measurements. Selected results of an aquifer test and a tracer test provided corroborating information in support of the flow-log analysis.

    Full Text Available HBase, a master-slave framework, and Cassandra, a peer-to-peer (P2P framework, are the two most commonly used large-scale distributed NoSQL databases, especially applicable to the cloud computing with high flexibility and scalability and the ease of big data processing. Regarding storage structure, different structure adopts distinct backup strategy to reduce the risks of data loss. This paper aims to realize high efficient remote cloud data center backup using HBase and Cassandra, and in order to verify the high efficiency backup they have applied Thrift Java for cloud data center to take a stress test by performing strictly data read/write and remote database backup in the large amounts of data. Finally, in terms of the effectiveness-cost evaluation to assess the remote datacenter backup, a cost-performance ratio has been evaluated for several benchmark databases and the proposed ones. As a result, the proposed HBase approach outperforms the other databases.

    Kagawa, Takahiro; Yamashina, Hideki; Uno, Yoji

    An efficient and stable gait control is an essential problem to develop a legged locomotor device for paraplegics. In this study, we investigate a necessary condition of the ballistic walking to avoid a backward balance loss. The condition derived by an inverted pendulum model is represented as a simple relationship between a position and velocity of a body center of mass at toe-off. The condition was validated through simulation experiments of a 7-link musculoskeletal model and gait measurement experiments of normal and paraplegic subjects. The results of the model simulation showed a good agreement with some predictions of the inverted pendulum model. The measured center of mass trajectories of normal and paraplegic gaits were satisfied with the necessary condition. These results suggest that the necessary condition is effective to avoid a backward falling during walking. In addition, energy input was required in a double support phase while the trajectory followed the ballistic movement of the inverted pendulum in a single support phase for a normal subject. These results suggest that a power assist control to be satisfied with the necessary condition during a double support phase and a ballistic gait generation during a single support phase are required for a paraplegic locomotor with efficiency and stability.

    2011-01-01

    Research suggests that perievent panic attacks – panic attacks in temporal proximity to traumatic events – are predictive of later mental health status, including the onset of depression. Using a community sample of New York City residents interviewed 1 year and 2 years after the World Trade Center Disaster, we estimated a structural equation model (SEM) using pre-disaster psychological status and post-disaster life events, together with psychosocial resources, to assess the relationship between perievent panic and later onset depression. Bivariate results revealed a significant association between perievent panic and both year-1 and year-2 depression. Results for the SEM, however, showed that perievent panic was predictive of year-1 depression, but not year-2 depression, once potential confounders were controlled. Year-2 stressors and year-2 psychosocial resources were the best predictors of year-2 depression onset. Pre-disaster psychological problems were directly implicated in year-1 depression, but not year-2 depression. We conclude that a conceptual model that includes pre- and post-disaster variables best explains the complex causal pathways between psychological status, stressor exposure, perievent panic attacks, and depression onset two years after the World Trade Center attacks.

    In this paper we deal with two classes of fractional partial differential equation: n order linear fractional partial differential equation and nonlinear fractional reaction diffusion convection equation, by using the Lie group analysis method. The infinitesimal generators general formula of n order linear fractional partial differential equation is obtained. For nonlinear fractional reaction diffusion convection equation, the properties of their infinitesimal generators are considered. The four special cases are exhaustively investigated respectively. At the same time some examples of the corresponding case are also given. So it is very convenient to solve the infinitesimal generator of some fractional partial differential equation.

    Full Text Available The setting of priorities among the various performance objectives is one of the main activities in the formulation of manufacturing strategy. Recognizing the importance of this activity and using the nomenclature of “perceived-value criteria”, this paper reports an analysis of competitive priorities of a fitness center, which was an essential part of a broader process aimed at the formulation of operations strategy for the company. After a brief literature review, the article proposes a model for the analysis of perceived-value criteria in service operations that, among other tools, makes use of importance-performance matrix and trade-off analysis. To validate its applicability, the proposed model was field-tested in an action research approach, in which one of the authors of this paper played the role of external facilitator of the process of organizational intervention. The application of the model allowed identifying the processes and the perceived-value criteria (PVC's that should be prioritized by the company, using for this, two bases of comparison: the direct competitors of its influence area and the benchmark fitness centers (best practices. As a result, the firm's managers were able to better decide about the different strategic alternatives to improve its operations.

    Surgery centers have been accepted as a cost effective, patient friendly vehicle for delivery of quality ambulatory care. Hospitals and physician groups also have made them the vehicles for coming together. Surgery centers allow hospitals and physicians to align incentives and share benefits. It is one of the few types of health care businesses physicians can own without anti-fraud and abuse violation. As a result, many surgery center ventures are now jointly owned by hospitals and physician groups. This article outlines common structures that have been used successfully to allow both to own and govern surgery centers.

    The glycerophosphodiesterase (GpdQ) from Enterobacter aerogenes is a promiscuous, dinuclear metallohydrolase that has potential application in the remediation of organophosphate nerve agents and pesticides. GpdQ employs an unusual reaction mechanism in which the enzyme is predominantly mononuclear in the resting state, and substrate binding induces the formation of the catalytically competent dinuclear center (Hadler et al. J. Am. Chem. Soc. 2008, 130, 14129). Reactivity is further modulated by the coordination flexibility of Asn80, a ligand that binds to the second, loosely bound metal ion (Hadler et al. J. Am. Chem. Soc. 2009, 131, 11900). It is proposed that hydrolysis is initiated by a terminal, metal-bound hydroxide molecule which is activated at unusually low pH by electrostatic/hydrogen bonding interactions with a bridging hydroxide species. In this study, electronic structure analysis of the dinuclear center is employed to study the coordination environment of the dinuclear center at the resting and product-bound stage of catalysis. This is achieved through the use of variable temperature, variable field magnetic circular dichroism experiments involving the Co(II)-substituted wild type enzyme and its Asn80Asp variant. The data support the above model for the catalytic mechanism whereby the metal ion-bridging hydroxide molecule activates a terminally bound hydroxide nucleophile. Replacement of Asn80 by an aspartate residue does prevent coordination flexibility but also leads to cleavage of the mu-hydroxide bridge and reduced reactivity. This is the first study to investigate the electronic structure of an enzyme with a mu-1,1-carboxylate bridged dicobalt(II) center.

    Current recommendations for diagnosing myelodysplastic syndromes endorse flow cytometry as an informative tool. Most flow cytometry protocols focus on the analysis of progenitor cells and the evaluation of the maturing myelomonocytic lineage. However, one of the most frequently observed features of myelodysplastic syndromes is anemia, which may be associated with dyserythropoiesis. Therefore, analysis of changes in flow cytometry features of nucleated erythroid cells may complement current flow cytometry tools. The multicenter study within the IMDSFlow Working Group, reported herein, focused on defining flow cytometry parameters that enable discrimination of dyserythropoiesis associated with myelodysplastic syndromes from non-clonal cytopenias. Data from a learning cohort were compared between myelodysplasia and controls, and results were validated in a separate cohort. The learning cohort comprised 245 myelodysplasia cases, 290 pathological, and 142 normal controls; the validation cohort comprised 129 myelodysplasia cases, 153 pathological, and 49 normal controls. Multivariate logistic regression analysis performed in the learning cohort revealed that analysis of expression of CD36 and CD71 (expressed as coefficient of variation), in combination with CD71 fluorescence intensity and the percentage of CD117+ erythroid progenitors provided the best discrimination between myelodysplastic syndromes and non-clonal cytopenias (specificity 90%; 95% confidence interval: 84–94%). The high specificity of this marker set was confirmed in the validation cohort (92%; 95% confidence interval: 86–97%). This erythroid flow cytometry marker combination may improve the evaluation of cytopenic cases with suspected myelodysplasia, particularly when combined with flow cytometry assessment of the myelomonocytic lineage.

    Smart home has recently attracted much research interest owing to its potential in improving the quality of human life. How to obtain user's demand is the most important and challenging task for appliance optimal scheduling in smart home, since it is highly related to user's unpredictable behavior. In this paper, a human-centered smart home system is proposed to identify user behavior, predict their demand and schedule the household appliances. Firstly, the sensor data from user's wearable devices are monitored to profile user's full-day behavior. Then, the appliance-demand matrix is constructed to predict user's demand on home environment, which is extracted from the history of appliance load data and user behavior. Two simulations are designed to demonstrate user behavior identification, appliance-demand matrix construction and strategy of appliance optimal scheduling generation.

    A preliminary survey of existing separation assurance and collision avoidance advancements, technologies, and efforts has been conducted in order to develop a concept of operations for flight testing autonomous separation assurance at Dryden Flight Research Center. This effort was part of the Unmanned Aerial Systems in the National Airspace System project. The survey focused primarily on separation assurance projects validated through flight testing (including lessons learned), however current forays into the field were also examined. Comparisons between current Dryden flight and range assets were conducted using House of Quality matrices in order to allow project management to make determinations regarding asset utilization for future flight tests. This was conducted in order to establish a body of knowledge of the current collision avoidance landscape, and thus focus Dryden s efforts more effectively towards the providing of assets and test ranges for future flight testing within this research field.

    Full Text Available Characterization of petroleum cuts constitutes a necessary stage to perfect understanding of the reaction mechanisms and to the description of the kinetics of certain refining processes such as hydrotreating or catalytic cracking. Mass spectrometry (MS, thanks to group-type quantitative analysis methods, enables to access detailed description of complex hydrocarbon mixtures such as middle distillates or heavy cuts such as vacuum distillates. But these methods are also subject to some drawbacks and we shall expose, thereunder, two examples of improvements. In a first part, the accuracy of MS quantification of thiophenic sulphured compounds in middle distillates is studied by intertechnique comparison with the results obtained by gas phase chromatography coupled to sulphur-specific detection by chemiluminescence (GC/SCD. Improving on the MS method is suggested. In the second part, a new system for introducing the sample in the spectrometer source, dedicated to group-type analysis of heavy cuts is described. Its validation, by comparison of the MS results to those of liquid chromatography (LC as well as its performances, is exposed.

  11. On Segal-Bargmann analysis for finite Coxeter groups and its heat kernel

    CERN Document Server

    Sontz, Stephen Bruce

    2009-01-01

    We prove identities involving the integral kernels of three versions of the Segal-Bargmann transform associated to a Coxeter group (defined by a finite root system) acting on a finite dimensional, real Euclidean space (one of these kernels having been introduced around the same time by Ben Said and Orsted and independently by Soltani) and the Dunkl heat kernel of the Dunkl Laplacian associated with the same Coxeter group, due to Rosler. All but one of our relations are originally due to Hall in the context of standard Segal-Bargmann analysis on Euclidean space. Hall's results (trivial Dunkl structure and arbitrary finite dimension) as well as our own results in mu-deformed quantum mechanics (non-trivial Dunkl structure, dimension one) are particular cases of the results proved here. So we can understand all of these versions of the Segal-Bargmann transform associated to a Coxeter group as Hall type transforms. In particular, we define an analogue of Hall's "Version C" generalized Segal-Bargmann transform whic...

    We study the dynamic interactions and structural changes in global financial indices in the years 1998-2012. We apply a principal component analysis (PCA) to cross-correlation coefficients of the stock indices. We calculate the correlations between principal components (PCs) and each asset, known as PC coefficients. A change in market state is identified as a change in the first PC coefficients. Some indices do not show significant change of PCs in market state during crises. The indices exposed to the invested capitals in the stock markets are at the minimum level of risk. Using the first two PC coefficients, we identify indices that are similar and more strongly correlated than the others. We observe that the European indices form a robust group over the observation period. The dynamics of the individual indices within the group increase in similarity with time, and the dynamics of indices are more similar during the crises. Furthermore, the group formation of indices changes position in two-dimensional spa...

  13. Supervised multivariate analysis of sequence groups to identify specificity determining residues

    2007-04-01

    Full Text Available Abstract Background Proteins that evolve from a common ancestor can change functionality over time, and it is important to be able identify residues that cause this change. In this paper we show how a supervised multivariate statistical method, Between Group Analysis (BGA, can be used to identify these residues from families of proteins with different substrate specifities using multiple sequence alignments. Results We demonstrate the usefulness of this method on three different test cases. Two of these test cases, the Lactate/Malate dehydrogenase family and Nucleotidyl Cyclases, consist of two functional groups. The other family, Serine Proteases consists of three groups. BGA was used to analyse and visualise these three families using two different encoding schemes for the amino acids. Conclusion This overall combination of methods in this paper is powerful and flexible while being computationally very fast and simple. BGA is especially useful because it can be used to analyse any number of functional classes. In the examples we used in this paper, we have only used 2 or 3 classes for demonstration purposes but any number can be used and visualised.

    We study the dynamic interactions and structural changes by a principal component analysis (PCA) to cross-correlation coefficients of global financial indices in the years 1998-2012. The variances explained by the first PC increase with time and show a drastic change during the crisis. A sharp change in PC coefficient implies a transition of market state, a situation which occurs frequently in the American and Asian indices. However, the European indices remain stable over time. Using the first two PC coefficients, we identify indices that are similar and more strongly correlated than the others. We observe that the European indices form a robust group over the observation period. The dynamics of the individual indices within the group increase in similarity with time, and the dynamics of indices are more similar during the crises. Furthermore, the group formation of indices changes position in two-dimensional spaces due to crises. Finally, after a financial crisis, the difference of PCs between the European and American indices narrows.

    Full Text Available Abstract Background To identify individual differences in physicians' needs for the presentation of evidence resources and preferences for mobile devices. Methods Within-groups analysis of responses to semi-structured interviews. Interviews consisted of using prototypes in response to task-based scenarios. The prototypes were implemented on two different form factors: a tablet style PC and a pocketPC. Participants were from three user groups: general internists, family physicians and medicine residents, and from two different settings: urban and semi-urban. Verbal protocol analysis, which consists of coding utterances, was conducted on the transcripts of the testing sessions. Statistical relationships were investigated between staff physicians' and residents' background variables, self-reported experiences with the interfaces, and verbal code frequencies. Results 47 physicians were recruited from general internal medicine, family practice clinics and a residency training program. The mean age of participants was 42.6 years. Physician specialty had a greater effect on device and information-presentation preferences than gender, age, setting or previous technical experience. Family physicians preferred the screen size of the tablet computer and were less concerned about its portability. Residents liked the screen size of the tablet, but preferred the portability of the pocketPC. Internists liked the portability of the pocketPC, but saw less advantage to the large screen of the tablet computer (F[2,44] = 4.94, p = .012. Conclusion Different types of physicians have different needs and preferences for evidence-based resources and handheld devices. This study shows how user testing can be incorporated into the process of design to inform group-based customization.

    Geologists usually deal with rocks that are up to several thousand million years old. They try to reconstruct the tectonic settings where these rocks were formed and the history of events that affected them through the geological time. The spinel group minerals provide useful information regarding the geological environment in which the host rocks were formed. They constitute excellent indicators of geological environments (tectonic settings) and are of invaluable help in the search for mineral deposits of economic interest. The current workflow requires the scientists to work with different applications to analyze spine data. They do use specific diagrams, but these are usually not interactive. The current workflow hinders domain experts to fully exploit the potentials of tediously and expensively collected data. In this paper, we introduce the Spinel Explorer-an interactive visual analysis application for spinel group minerals. The design of the Spinel Explorer and of the newly introduced interactions is a result of a careful study of geologists' tasks. The Spinel Explorer includes most of the diagrams commonly used for analyzing spinel group minerals, including 2D binary plots, ternary plots, and 3D Spinel prism plots. Besides specific plots, conventional information visualization views are also integrated in the Spinel Explorer. All views are interactive and linked. The Spinel Explorer supports conventional statistics commonly used in spinel minerals exploration. The statistics views and different data derivation techniques are fully integrated in the system. Besides the Spinel Explorer as newly proposed interactive exploration system, we also describe the identified analysis tasks, and propose a new workflow. We evaluate the Spinel Explorer using real-life data from two locations in Argentina: the Frontal Cordillera in Central Andes and Patagonia. We describe the new findings of the geologists which would have been much more difficult to achieve using the

    A reliability analysis was performed on 64 strain gage systems mounted on the 3 rotor stages of the fan of a YF-100 engine. The strain gages were used in a 65 hour fan flutter research program which included about 5 hours of blade flutter. The analysis was part of a reliability improvement program. Eighty-four percent of the strain gages survived the test and performed satisfactorily. A post test analysis determined most failure causes. Five failures were caused by open circuits, three failed gages showed elevated circuit resistance, and one gage circuit was grounded. One failure was undetermined.

    Full Text Available Background Treatment for psychological disorders is generally based on signs and symptoms, and research in this area has shown that major depression has become one of the most significant psychiatric disorders of the last decade. Objectives This study was conducted to compare the effects of schema therapy and cognitive group therapy on women with depression who were engaging in high-risk sexual behaviors and were referred to the Hamadan Health Center for AIDS testing. Patients and Methods This research was done at the Hamadan shohada infirmary from 2015 to 2016 and was confirmed by the ethics committee of Hamadan University of Medical Sciences. It was a semi-experimental study using single stage cluster sampling. The statistical sample consisted of 500 women ranging in age from 20 to 60 years old with at least a diploma. The women were engaging in high-risk sexual behaviors and were referred to the health center for AIDS testing. Psychologists and a physician conducted a diagnostic interview, and 217 subjects were randomly chosen using a sample volume formula, in addition to Depression Anxiety Stress Scales (DASS. Eighty five of the subjects were diagnosed with depression, of whom 45 were chosen randomly and divided into three groups of 15 consisting of two experimental groups and one control group. Twelve sessions of cognitive group therapy and 12 sessions of schema therapy were implemented for 90 minutes per session. At the end of the training period, the three groups were post-tested and depression components were then investigated in the pretest and post-test results. Results The findings support the idea that a significant difference exists in terms of the mean of depression between schema therapy and cognitive therapy, as follows: F (1, 41 = 60.650 P < 0.01. Conclusions The results show that schema therapy is more effective than cognitive group therapy for treating depression in women engaging in high-risk sexual behaviors.

    1994-01-01

    A radioresistant cell clone (1B3) was previously isolated after transfection of an ataxia-telangiectasia (AT) group D cell line with a human cosmid library. A cosmid rescued from the integration site in 1B3 contained human DNA from chromosome position 11q23, the same region shown by both genetic linkage and chromosome transfer to contain the genes for AT complementation groups A/B, C, and D. A gene within the cosmid (ATDC) was found to produce mRNAs of different sizes. A cDNA for one of the most abundant mRNAs (3.0 kb) was isolated from a HeLa cell library. In the present study, the authors sequenced the 3.0-kb cDNA and the surrounding intron DNA in the cosmids. They used polymerase chain reaction, with primers in the introns, to confirm the number of exons and to analyze DNA from AT group D cells for mutations within this gene. Although no mutations were found, they do not rule out the possibility that mutations may be present within the regulatory sequences or coding sequences found in other mRNAs specific for this gene. From the sequence analysis, they found that the ATDC gene product is one of a group of proteins that share multiple zinc finger motifs and an adjacent leucine zipper motif. These proteins have been proposed to form homo- or hetero-dimers involved in nucleic acid binding, consistent with the fact that many of these proteins appear to be transcriptional regulatory factors involved in carcinogenesis and/or differentiation. The likelihood that the ATDC gene product is involved in transcriptional regulation could explain the pleiomorphic characteristics of AT, including abnormal cell cycle regulation. 36 refs., 5 figs., 2 tabs.

    2015-01-01

    Microbial communities in glacial ecosystems are diverse, active, and subjected to strong viral pressures and infection rates. In this study we analyse putative virus genomes assembled from three dsDNA viromes from cryoconite hole ecosystems of Svalbard and the Greenland Ice Sheet to assess the potential hosts and functional role viruses play in these habitats. We assembled 208 million reads from the virus-size fraction and developed a procedure to select genuine virus scaffolds from cellular contamination. Our curated virus library contained 546 scaffolds up to 230 Kb in length, 54 of which were circular virus consensus genomes. Analysis of virus marker genes revealed a wide range of viruses had been assembled, including bacteriophages, cyanophages, nucleocytoplasmic large DNA viruses and a virophage, with putative hosts identified as Cyanobacteria, Alphaproteobacteria, Gammaproteobacteria, Actinobacteria, Firmicutes, eukaryotic algae and amoebae. Whole genome comparisons revealed the majority of circular genome scaffolds (CGS) formed 12 novel groups, two of which contained multiple phage members with plasmid-like properties, including a group of phage-plasmids possessing plasmid-like partition genes and toxin-antitoxin addiction modules to ensure their replication and a satellite phage-plasmid group. Surprisingly we also assembled a phage that not only encoded plasmid partition genes, but a clustered regularly interspaced short palindromic repeat (CRISPR)/Cas adaptive bacterial immune system. One of the spacers was an exact match for another phage in our virome, indicating that in a novel use of the system, the lysogen was potentially capable of conferring immunity on its bacterial host against other phage. Together these results suggest that highly novel and diverse groups of viruses are present in glacial environments, some of which utilize very unusual life strategies and genes to control their replication and maintain a long-term relationship with their hosts

    Next-generation sequencing (NGS) analysis has emerged as a promising molecular epidemiological method for investigating health care-associated outbreaks. Here, we used NGS to investigate a 3-year outbreak of multidrug-resistant Acinetobacter baumannii (MDRAB) at a large academic burn center. A reference genome from the index case was generated using de novo assembly of PacBio reads. Forty-six MDRAB isolates were analyzed by pulsed-field gel electrophoresis (PFGE) and sequenced using an Illumina platform. After mapping to the index case reference genome, four samples were excluded due to low coverage, leaving 42 samples for further analysis. Multilocus sequence types (MLST) and the presence of acquired resistance genes were also determined from the sequencing data. A transmission network was inferred from genomic and epidemiological data using a Bayesian framework. Based on single-nucleotide variant (SNV) differences, this MDRAB outbreak represented three sequential outbreaks caused by distinct clones. The first and second outbreaks were caused by sequence type 2 (ST2), while the third outbreak was caused by ST79. For the second outbreak, the MLST and PFGE results were discordant. However, NGS-based SNV typing detected a recombination event and consequently enabled a more accurate phylogenetic analysis. The distribution of resistance genes varied among the three outbreaks. The first- and second-outbreak strains possessed a blaOXA-23-like group, while the third-outbreak strains harbored a blaOXA-40-like group. NGS-based analysis demonstrated the superior resolution of outbreak transmission networks for MDRAB and provided insight into the mechanisms of strain diversification between sequential outbreaks through recombination.

    Full Text Available Background/Aim. Necrotizing fasciitis (NF is usually an acute infection of superficial fascia with rapid progression in around soft tissue. If not promptly recognized and aggressively treated NF usualy leads to sepsis and multiorgan failure with fatal outcome, thus early diagnosis and prompt surgical treatment are crucial for healing of these patients. The aim of this article was to evaluate the clinical presentation of all patients with acute NF diagnosed and treated in surgical clinics of Clinical Center of Vojvodina, Novi Sad, Serbia. Methods. The medical records of patients treated for acute NF localized on a different parts of the body in Clinical Center of Vojvodina, Novi Sad, Serbia, during a 5- year period (from January 2008 to December 2012 were retrospectively evaluated. This study enrolled patients admitted via Emergency Center of Vojvodina with the diagnosis of acute NF either as the primary diagnosis or with the diagnosis at discharge after surgical treatment. Results. During a 5-year period there were 216 patients with final diagnosis of acute NF. Most of our patients (140 - 64.81% were admitted with the initial diagnosis of cellulitis, abscesses, phlegmons or sepsis. Unfortunately, the clinical symptoms of acute NF were atypical at time of initial examination. Pain and swelling of the affected localization were the most presented bias of symptoms (183 - 84.72%. The majority of our patients were male (164 - 75.92%. Among the 216 patients, the most common pre-existing single factor was drug abuse (39 - 18.05%, followed by obesity (38 - 17.59% and diabetes mellitus (31 - 14.35%. Trauma was most common etiological factor (22 - 10.8% in infected wounds, followed by abdominal (15 - 6.94% and orthopedic (11 - 5.09% surgical intervention. In the present study idiopathic acute NF was diagnosed in 22 (10.18% patients and more than one etiological factor were diagnosed in 20 (9.25% patients. The majority of our patients had type I acute NF

    Lei-Jie Lai

    2016-11-01

    Full Text Available The remote center compliance (RCC mechanism is of great use for practical designs, especially if a pure rotation about a virtual point is required. The analysis of compliance properties and rotational precision for RCC mechanisms are very important for mechanical design in applications where precision is required. This paper formulates an analytical method for the compliance and rotational precision calculations of a class of RCC mechanisms, combined in parallel with two round beam-based isosceles-trapezoidal flexural pivots. The analytical model of the mechanism is established based on the stiffness matrix method to directly obtain the compliance factors that completely define the elastic response of the mechanism. The rotational precision of the mechanism—That is, the position of rotation center—Is then derived using screw theory and a compliance matrix. The validity of this model is demonstrated using finite element analysis simulation and experimental tests. The results of both simulation and experiment verify that the analytical model has high accuracy and promising practical applications. Moreover, the influences of the geometry parameters on the compliance factors and the center shifts are also graphically evaluated and discussed using the analytical model. The results in this paper provide an effective configuration and analytical method for the design and optimization of RCC mechanisms, and are of great practical significance.

    Abstract Background Group B Streptococcus (GBS) serotype (Ia, Ib, II-IX) correlates with pathogen virulence and clinical prognosis. Epidemiological studies of seroprevalence are an important metric for determining the proportion of serotypes in a given population. The purpose of this study was to evaluate the prevalence of individual GBS serotypes at Madigan Healthcare System (Madigan), the largest military tertiary healthcare facility in the Pacific Northwestern United States, and to compare...

    A process task analysis effort was undertaken by Dynacs Inc. commencing in June 2002 under contract from NASA YA-D6. Funding was provided through NASA's Ames Research Center (ARC), Code M/HQ, and Industrial Engineering and Safety (IES). The John F. Kennedy Space Center (KSC) Engineering Development Contract (EDC) Task Order was 5SMA768. The scope of the effort was to conduct a Human Factors Process Failure Modes and Effects Analysis (HF PFMEA) of a hazardous activity and provide recommendations to eliminate or reduce the effects of errors caused by human factors. The Liquid Oxygen (LOX) Pump Acceptance Test Procedure (ATP) was selected for this analysis. The HF PFMEA table (see appendix A) provides an analysis of six major categories evaluated for this study. These categories include Personnel Certification, Test Procedure Format, Test Procedure Safety Controls, Test Article Data, Instrumentation, and Voice Communication. For each specific requirement listed in appendix A, the following topics were addressed: Requirement, Potential Human Error, Performance-Shaping Factors, Potential Effects of the Error, Barriers and Controls, Risk Priority Numbers, and Recommended Actions. This report summarizes findings and gives recommendations as determined by the data contained in appendix A. It also includes a discussion of technology barriers and challenges to performing task analyses, as well as lessons learned. The HF PFMEA table in appendix A recommends the use of accepted and required safety criteria in order to reduce the risk of human error. The items with the highest risk priority numbers should receive the greatest amount of consideration. Implementation of the recommendations will result in a safer operation for all personnel.

    Full Text Available Functional magnetic resonance imaging (fMRI is a powerful tool for the in vivo study of the pathophysiology of brain disorders and disease. In this manuscript, we propose an analysis stream for fMRI functional connectivity data and apply it to a novel study of Alzheimer's disease. In the first stage, spatial independent component analysis is applied to group fMRI data to obtain common brain networks (spatial maps and subject-specific mixing matrices (time courses. In the second stage, functional principal component analysis is utilized to decompose the mixing matrices into population-level eigenvectors and subject-specific loadings. Inference is performed using permutation-based exact logistic regression for matched pairs data. The method is applied to a novel fMRI study of Alzheimer's disease risk under a verbal paired associates task. We found empirical evidence of alternative ICA-based metrics of connectivity when comparing subjects evidencing mild cognitive impairment relative to carefully matched controls.

    This article sets out to establish the naturalistic study of online social communication as a substantive topic in social psychology and to discuss the challenges of developing methods for a formal analysis of the structural and interactional features of message threads on discussion forums. I begin by outlining the essential features of online communication and specifically discussion forum data, and the important ways in which they depart from spoken conversation. I describe the handful of attempts to devise systematic analytic techniques for adapting methods such as conversation and discourse analysis to the study of online discussion. I then present a case study of a thread from the popular UK parenting forum Mumsnet which presents a number of challenges for existing methods, and examine some of the interactive phenomena typical of forums. Finally, I consider ways in which membership categorization analysis and social identity theory can complement one another in the exploration of both group processes and the rhetorical deployment of identities as dynamic phenomena in online discussion.

    Background: The reports on massive transfusions (MTs) in obstetrics have recently been an increasing trend. We aimed to define the clinical features, risk factors, main causes, and outcomes of MTs due to severe postpartum hemorrhage (PPH) and the frequency trends over the past 10 years. Methods: We retrospectively analyzed the data of 3552 PPH patients who were at ≥28 weeks of gestation in the Obstetric Department of Peking University First Hospital from January 2006 to February 2015. The clinical records of patients receiving MT with ≥5 units (approximately 1000 ml) of red blood cells within 24 h of giving birth were included. The Pearson's Chi-square and Fisher's exact tests were used to compare the frequency distributions among the categorical variables of the clinical features. Results: One-hundred six women were identified with MT over the 10-year period. The MT percentage was stable between the first 5-year group (2006–2010) and the second 5-year group (2011–2015) (2.5‰ vs. 2.7‰, χ2 = 154.85, P = 0.25). Although uterine atony remained the main cause of MT, there was a rising trend for placental abnormalities (especially placenta accreta) in the second 5-year group compared with the first 5-year group (34% vs. 23%, χ2 = 188.26, P = 0.03). Twenty-four (23%) women underwent hysterectomy, and among all the causes of PPH, placenta accreta had the highest hysterectomy rate of 70% (17/24). No maternal death was observed. Conclusions: There was a rising trend for placental abnormalities underlying the stable incidence of MT in the PPH cases. Placenta accreta accounted for the highest risk of hysterectomy. It is reasonable to have appropriate blood transfusion backup for high-risk patients, especially those with placenta accreta. PMID:28229990

    Full Text Available The entry-level skills for students enrolling in a college-level information systems course can vary widely. This paper analyzes the impact of a "student-centered" pedagogy model, in which students use a self-paced approach for learning the material in an introductory information systems course, with pre-assigned dates for lectures and for assignment/exam deadlines. This new paradigm was implemented in several sections of an introductory information systems course over a two-semester time span. Under the new model, tutorial-style textbooks were used to help students master the material, all other materials were available online, and all exams were given using a hands-on, task-oriented online testing package, which included a multiple-choice/true-false component to test student understanding of the conceptual portion of the course. An anonymous student survey was used to gain student perceptions of the level of learning that took place under the new paradigm, as well as to measure student satisfaction with the course design, and a pre-/post-test was used to provide a measure of student learning.

    Full Text Available Background: Psychosexual problems are very common presentation, be it with psychiatric or physical illness but there are very few studies available on psychosexual disorders especially in the Indian context. Indian society is deeply ingrained in customs and several misconceptions, myths, prejudices, and social taboos are attached to sex which makes it further very difficult to tackle. Objectives: The aim of this current study was to descriptively analyze the nature of sexual disorders in a tertiary care center. Materials and Methods: The current retrospective chart review included 698 consecutive subjects seeking treatment for their psychosexual problems at the Sexual Clinic, Department of Psychiatry, Dr. Ram Manohar Hospital, New Delhi (between 2006 and 2010. Results: This study observed erectile dysfunction (ED (29.5%, Premature ejaculation (PME (24.6%, Dhat syndrome (DS (18.1%, and ED with PME (17.5% as the common sexual dysfunctions leading to treatment seeking. DS was the major complaint among younger and unmarried individuals. We observed more married individuals seeking treatment for sexual disorders. Conclusions: These findings provide important information on a relatively under-researched area.

    Full Text Available In this paper, we address the topic of user-centered design (UCD for cartography, GIScience, and visual analytics. Interactive maps are ubiquitous in modern society, yet they often fail to “work” as they could or should. UCD describes the process of ensuring interface success—map-based or otherwise—by gathering input and feedback from target users throughout the design and development of the interface. We contribute to the expanding literature on UCD for interactive maps in two ways. First, we synthesize core concepts on UCD from cartography and related fields, as well as offer new ideas, in order to organize existing frameworks and recommendations regarding the UCD of interactive maps. Second, we report on a case study UCD process for GeoVISTA CrimeViz, an interactive and web-based mapping application supporting visual analytics of criminal activity in space and time. The GeoVISTA CrimeViz concept and interface were improved iteratively by working through a series of user→utility→usability loops in which target users provided input and feedback on needs and designs (user, prompting revisions to the conceptualization and functional requirements of the interface (utility, and ultimately leading to new mockups and prototypes of the interface (usability for additional evaluation by target users (user… and so on. Together, the background review and case study offer guidance for applying UCD to interactive mapping projects, and demonstrate the benefit of including target users throughout design and development.

    Background Simultaneous pancreas-kidney transplantation (SPKT) is the best treatment option for diabetic patients with advanced chronic renal failure. The current study aimed to analyze the surgical indications, treatments and prognosis of SPKT.Methods We retrospectively analyzed 40 cases of SPKT performed between December 1999 and January 2010 in our center, including the survival rate, complications and the reasons of reoperation.Results Of all the 40 SPKT cases, the one-year survival rates of the recipients, kidney and pancreas transplant graft were 97.6%, 97.6% and 92.7%, while 97.6%, 91.1%, 92.7% at 3 years and 83.6%, 78.0%, 79.4% at 5 years, respectively.After SPKT, 10 patients need reoperation because of surgical complications (14 operations). The reoperation rate was 25%, including 2 patients (4 operations) with hematuria, 4 patients with abdominal hemorrhage, 2 patients (3 operations)with abdominal infection, 1 patient with pancreatic venous thrombosis, 1 patient with anastomotic leakage, and 1 patient with fistula.Conclusion Although SPKT provides a successful and effective treatment for diabetics with end-stage renal disease,how to reduce the complications of this treatment still need further effort.

    We present consistent modelling of line and continuum IR spectra in the region close to the Galactic center. The models account for the coupled effect of shocks and photoionization from an external source. The results show that the shock velocities range between 65 and 80 km/s, the pre-shock densities between 1 cm-3 in the ISM to 200 cm-3 in the filamentary structures. The pre-shock magnetic field increases from 5. 10^{-6} gauss in the surrounding ISM to ~8. 10^{-5} gauss in the Arched Filaments. The stellar temperatures are ~38000 K in the Quintuplet cluster and ~27000 K in the Arches Cluster. The ionization parameter is relatively low (0.01 near the Arches Cluster. Depletion from the gaseous phase of Si is found throughout the whole observed region, indicating the presence of silicate dust. Grains including iron, are concentrated throughout the Arched Filaments. The modelling of the continuum SED in the IR range, indicates that a component of dust at temperatures of ~100-200 K is present in the central regi...

    Acquired hemophilia A (AHA) is a rare bleeding disorder caused by the autoantibody directed against factor VIII in patients without previous history of a bleeding disorder. We retrospectively analyzed the characteristics and outcomes of 49 patients with AHA diagnosed in our center from February 1994 to October 2012. Twenty-four patients with acute bleeding episodes were treated with prothrombin complex concentrate (PCC) at a relative low dose of 30 to -50 U/kg/d and achieved good outcomes without any adverse reaction. Corticosteroids alone or in combination with cyclophosphamide were used as the first-line therapy to eradicate the inhibitors. In 39 evaluable patients, 35 (89.7%) achieved complete remission (CR). This study demonstrates that when bypassing agents such as recombinant activated factor VII and activated PCCs are not affordable or available, low dose PCC is effective and safe to control acute bleeding in patients with AHA. First-line therapy achieved good outcomes with a CR rate of 89.7%.
