  3. The master degree: A critical transition in STEM doctoral education

    Science.gov (United States)

    Lange, Sheila Edwards

    The need to broaden participation in the nation's science, technology, engineering, and mathematics (STEM) undergraduate and graduate programs is currently a matter of national urgency. The small number of women and underrepresented minorities (URM) earning doctoral degrees in STEM is particularly troubling given significant increases in the number of students earning master's degrees since 1990. In the decade between 1990 and 2000, the total number of master's recipients increased by 42%. During this same time period, the number of women earning master's degrees increased by 56%, African Americans increased by 132%, American Indians by 101%, Hispanics by 146%, and Asian Americans by 117% (Syverson, 2003). Growth in underrepresented group education at the master's level raises questions about the relationship between master's and doctoral education. Secondary data analysis of the Survey of Earned Doctorates (SED) was used to examine institutional pathways to the doctorate in STEM disciplines and transitions from master's to doctoral programs by race and gender. While the study revealed no significant gender differences in pathways, compared to White and Asian American students, URM students take significantly different pathways to the doctorate. URM students are significantly more likely to earn the bachelor's, master's, and doctoral degrees at three different institutions. Their path is significantly more likely to include earning a master's degree en route to the doctorate. Further, URM students are more likely to experience transition between the master's and doctoral degrees, and the transitions are not limited to those who earn master's degrees at master's-only institutions. These findings suggest that earning a master's degree is more often a stepping stone to the doctorate for URM students. Master's degree programs, therefore, have the potential to be a valuable resource for policymakers and graduate programs seeking to increase the diversity of URM students

    2000-12-01

    Graduates' assessments of the University of Texas at Austin's nontraditional M.S. degree program in pharmacy administration were studied. A survey was constructed to assess the impact of the master's program on career advancement, to examine why pharmacists enrolled in the program, and to determine if the curriculum provided knowledge or developed skills that were practical or beneficial. The survey was mailed in April 1999 to all persons who had completed the program between 1990 and 1998. A total of 56 graduates responded, for a response rate of 90.3%. The three reasons for entering the program most frequently cited as most important were career advancement, personal development, and the desire to change job responsibilities. Thirty-four respondents (60.7%) reported receiving a promotion or changing jobs for a higher position while they were enrolled in the program or after completing it. Of these 34 respondents, 29 (85.3%) attributed their promotion or new job to the master's degree. On average, graduates reported that the knowledge and skills obtained through the program had been useful in their practice. The benefits of the program that were cited most frequently were management skills, competencies in areas of pharmacy business, opportunity to advance career, job satisfaction, and competitive advantage when applying for a job. A nontraditional master's degree program in pharmacy administration had a positive impact on the career paths of graduates.

    Sustainable development has become a key aspect in society, economics and environment. Therefore, experts dealing with questions relating to people, the environment and its resources are more and more requested. This paper presents the concept and first experiences of a specialised Master's Degree in Sustainable Development (MSD). This is a pioneer course as it is equally anchored in three faculties (Human science, Natural science, Business and Economy) at the University of Basel, Switzerland. It aims to transmit knowledge, teach methodology and enable practical work experience in the field of sustainable development. This interdisciplinary master's degree is composed of several modules. At first, the attendance of modules providing a basic understanding in the disciplines not yet covered by the former Bachelor degree, is mandatory. In optional modules, the acquired knowledge of the compulsory modules is further enhanced, focussing on four different topics and are titled as: Agglomeration and Ecosystems; Conservation and Utilisation of Natural Resources; Environment, Values, Societal Transformation and Health; and Environmental Problems in a Globalised World. In another optional module, students may complete an internship in which they can apply theoretical and thematic knowledge. To work independently on a problem in the context of, interdisciplinary projects are a central request in the MSD. Finally, the master thesis has to be planned and realized by a plying the scientific methods and skills acquired in the previous modules. Since the beginning of the programme in the winter of 2005/2006, 45 students have enrolled. They received degrees at 25 different universities, 13 of which are from abroad. Some already have several years of working experience, while others have only just completed their Bachelor's degrees. A analysis has shown that the graduates will have excellent chances in the employment market, since they are well qualified to take over sought

    The Doctor of Philosophy is the highest academic degree that can be obtained in universities. Graduate Education Program in Medicine in Mexico is divided into 2 major categories: Medical Specialty and Master studies/Doctor of Philosophy. The objective of this study was to demonstrate the importance of master's degrees and Doctor of Philosophy in general surgery. A literature search in PubMed and Medline among others, from 1970 to 2015 with subsequent analysis of the literature reviews found. The physicians who conducted doctoral studies stand out as leaders in research, teaching and academic activities. Dual training with a doctorate medical specialty is a significant predictor for active participation in research projects within the best educational institutions. It is important to study a PhD in the education of doctors specialising in surgery, who show more training in teaching, research and development of academic activities. Currently, although there is a little proportion of students who do not finish the doctoral program, the ones who do are expected to play an important role in the future of medical scientific staff. It has been shown that most doctors with Doctor of Philosophy have wide range of career options. The importance of doctoral studies in the formation of general surgery is due to various reasons; the main one being comprehensively training physician scientists who can develop in clinical, teaching and research.

    1991-01-01

    After defining a network and conveying its importance to support the activities at the JSC, the need for network management based on the size and complexity of the IBM SNA network at JSC is demonstrated. Network Management consists of being aware of component status and the ability to control resources to meet the availability and service needs of users. The concerns of the user are addressed as well as those of the staff responsible for managing the network. It is explained how NetMaster (a network management system for managing SNA networks) is used to enhance reliability and maximize service to SNA network users through automated procedures. The following areas are discussed: customization, problem and configuration management, and system measurement applications of NetMaster. Also, several examples are given that demonstrate NetMaster's ability to manage and control the network, integrate various product functions, as well as provide useful management information.

    Drennan, Jonathan

    2010-02-01

    This paper is a report of a study measuring critical thinking ability in graduates on completion of a Master's degree in Nursing. Nurse education programmes identify the development of critical thinking capabilities as a central outcome for graduates at Master's level. However, despite the centrality of critical thinking to educational curricula, achievement of this outcome has not been evaluated. A cross-sectional cohort study was conducted in Ireland between 2006 and 2007. Critical thinking was measured using the Watson-Glaser Critical Thinking Appraisal tool. The sample consisted of two cohorts: a control cohort (110 students commencing Master's in Nursing programmes) and an outcome cohort (222 students who had a Master's degree in Nursing). The Watson-Glaser Critical Thinking Appraisal scores of the graduate cohort were also compared to previously published norm reference scores in the area of nursing and other higher education professional groups. Graduates had statistically significantly higher critical thinking scores than commencing graduates. Graduates from Master's in Nursing programmes also had similar critical thinking scores to nurses at undergraduate and postgraduate levels in the United States of America. However, scores were lower than those of occupational and academic groups in education and medicine. Graduates from a Master's degree in Nursing make statistically significant gains in critical thinking scores when compared to students commencing the programme. However, the gains were relatively modest and call into question the effectiveness of pedagogical methods used to facilitate the development of critical thinking at Master's level.

  3. Synchronization Analysis of Master-Slave Probabilistic Boolean Networks.

    2015-08-28

    In this paper, we analyze the synchronization problem of master-slave probabilistic Boolean networks (PBNs). The master Boolean network (BN) is a deterministic BN, while the slave BN is determined by a series of possible logical functions with certain probability at each discrete time point. In this paper, we firstly define the synchronization of master-slave PBNs with probability one, and then we investigate synchronization with probability one. By resorting to new approach called semi-tensor product (STP), the master-slave PBNs are expressed in equivalent algebraic forms. Based on the algebraic form, some necessary and sufficient criteria are derived to guarantee synchronization with probability one. Further, we study the synchronization of master-slave PBNs in probability. Synchronization in probability implies that for any initial states, the master BN can be synchronized by the slave BN with certain probability, while synchronization with probability one implies that master BN can be synchronized by the slave BN with probability one. Based on the equivalent algebraic form, some efficient conditions are derived to guarantee synchronization in probability. Finally, several numerical examples are presented to show the effectiveness of the main results.

    2015-08-01

    To determine perceptions about dental hygiene doctoral education among dental hygiene master's degree program enrollees. In this cross-sectional national study, all dental hygiene master degree program directors were sent an email requesting they forward an attached consent form and online-survey-link to their graduate learners. The 29-item online survey assessed their perceptions about need for, importance of and interest in applying to proposed dental hygiene doctoral degree programs. A second-request was sent 1 month later to capture non-responders. Frequencies and cross-tabulations of responses were analyzed using the online software program, Qualtrics.™ Of the 255 graduate learners enrolled in 2014 reported by dental hygiene program directors, 159 completed the survey for a 62% response rate. The majority of respondents (77%) indicated that doctoral education in dental hygiene is needed for the advancement of the dental hygiene discipline and such programs are important to the dental hygiene profession (89%). Although most respondents supported both the PhD in dental hygiene and the Doctor of Dental Hygiene Practice (DDHP) degrees, more were interested in applying to a DDHP program (62%) than to a dental hygiene PhD program (38%). In addition, 43% expressed interest in enrolling in a doctoral degree program in the next 1 to 5 years and most preferred a hybrid online/onsite program format. The most frequently reported reasons for pursing a doctoral degree were: to become a better teacher, to expand clinical practice opportunities, to become a better researcher and to increase salary. Most dental hygiene master degree learners in this study believed doctoral dental hygiene education is needed and important to the dental hygiene discipline and profession, and were interested in applying to such programs. Future research is needed in this area. Copyright © 2015 The American Dental Hygienists’ Association.

    2000-01-01

    The primary objectives of this study were to assess career and degree satisfaction as well as job characteristics of individuals graduating from programs awarding the master of science in dental hygiene or dental hygiene education degree. A pilot-tested questionnaire was mailed to all 252 individuals who graduated between 1980 and 1995 from eight dental hygiene master's degree programs (MSDH). The questionnaire included both closed- and open-ended items regarding career history/career path, career satisfaction, professional involvement, and opinions/perceptions about the graduate program the participant attended. Responses were analyzed using descriptive statistics and two-way tables. After three complete mailings, the response rate was 69% (n = 174). The majority of respondents reported currently working approximately five days per week (54%), with 62% having annual salaries over $40,000. Eighty-six percent were satisfied overall with their career choices, although 30% stated that they would not pursue the same degree again. Overall, graduates from MSDH programs are satisfied with their degree choice as well as the opportunities it has afforded them. These findings serve to expand the knowledge base of graduate dental hygiene education and of the graduates from these programs as well as provide suggestions for improvement to graduate dental hygiene programs.

    The field of health communication has seen substantial growth in recent years, but existing health communication research literature contains little information on individuals who practice health communication in applied settings. This study reports the results of a national survey that targeted the alumni of 5 institutions that offer a master's degree in health communication. Of the 522 total graduates to whom the survey was sent, 398 responded. Survey results provided information in a number of areas including undergraduate education background; criteria used to determine what type of master's degree in health communication to pursue; strategies used to gain employment; employment sector of first job after graduation; salaries received after completion of a master's degree in health communication; satisfaction with career choice after completion of master's degree; satisfaction with type of master's degree in health communication received; satisfaction with career choice after completion of master's degree; and the degree to which respondents felt their master's program in health communication prepared them to meet core competencies in the field. These findings have significant implications for the health communication field and the programs that prepare individuals for a career as a health communication practitioner.

  15. Degree heterogeneity and stability of ecological networks.

    Yan, Gang; Martinez, Neo D; Liu, Yang-Yu

    2017-06-01

    A classic measure of ecological stability describes the tendency of a community to return to equilibrium after small perturbations. While many advances show how the network architecture of these communities severely constrains such tendencies, one of the most fundamental properties of network structure, i.e. degree heterogeneity-the variability of the number of links associated with each species, deserves further study. Here we show that the effects of degree heterogeneity on stability vary with different types of interspecific interactions. Degree heterogeneity consistently destabilizes ecological networks with both competitive and mutualistic interactions, while its effects on networks of predator-prey interactions such as food webs depend on prey contiguity, i.e. the extent to which the species consume an unbroken sequence of prey in community niche space. Increasing degree heterogeneity tends to stabilize food webs except those with the highest prey contiguity. These findings help explain why food webs are highly but not completely interval and, more broadly, deepen our understanding of the stability of complex ecological networks. © 2017 The Author(s).

    The debate over what the entry-level degree should be for athletic training has heightened. A comparison of retention and career-placement rates between bachelor's and master's degree professional athletic training programs may inform the debate. To compare the retention rates and career-placement rates of students in bachelor's and master's degree professional programs. Cross-sectional study. Web-based survey. A total of 192 program directors (PDs) from bachelor's degree (n = 177) and master's degree (n = 15) professional programs. The PDs completed a Web-based survey. We instructed the PDs to provide a retention rate and career-placement rate for the students in the programs they lead for each of the past 5 years. We also asked the PDs if they thought retention of students was a problem currently facing athletic training education. We used independent t tests to compare the responses between bachelor's and master's degree professional programs. We found a higher retention rate for professional master's degree students (88.70% ± 9.02%, 95% confidence interval [CI] = 83.71, 93.69) than bachelor's degree students (80.98% ± 17.86%, 95% CI = 78.30, 83.66) (t25 = -2.86, P = .008, d = 0.55). Similarly, PDs from professional master's degree programs reported higher career-placement percentages (88.50% ± 10.68%, 95% CI = 82.33, 94.67) than bachelor's degree professional PDs (71.32% ± 18.47%, 95% CI = 68.54, 74.10) (t20 = -5.40, P training (χ(2)1 = 0.720, P = .40, Φ = .061). Professional master's degree education appears to facilitate higher retention rates and greater career-placement rates in athletic training than bachelor's degree education. Professional socialization, program selectivity, and student commitment and motivation levels may help to explain the differences noted.

    Advanced education in nursing is essential to provide safe, high quality and efficient health services in line with population needs. However, there is an almost complete lack of studies on how nurses view the usefulness of post-graduate education for their current employment and for professional advancement. To evaluate how nurse graduates view the quality, relevance and applicability of the knowledge and skills acquired during the Master of Science in Nursing (MSN) degree. Multicentre cross-sectional study. A multicenter cross-sectional study was carried out through an online questionnaire mailed (July 2014-June 2015) to 560 nurses who obtained the MSN degree from 23 Italian universities in the academic year 2010-2011. A total of 426 nurses completed the survey (response rate 76.1%), 80% of whom believed they had acquired knowledge and skills useful in their professional life after graduation. A multiple logistic regression model highlighted the characteristics of nurse graduates who judged the master's course relevant for their present role. In brief, they are expert nurses (OR=3.41, 95% CI=1.54-7.54) who achieved professional growth after the course (OR=5.25, 95% CI=2.67-10.33) and who judged the course very good or excellent (OR=2.16, 95% CI=1.04-4.52). Only 8% of the respondents achieved a full professional growth after the course. In Italy, MSN courses are able to provide a high level of skills and competencies. However, given the low rate of professional growth after the course, specific policies should increase the employment rates of new master's graduate nurses. Copyright © 2017 Elsevier Ltd.

    Objectives. To examine pharmacist-targeted master of business administration (MBA) degree programs and investigate pharmacists’ perceptions regarding them. Methods. Specialized MBA programs in pharmaceutical marketing and management offered at US colleges and schools of pharmacy were identified in the literature and compared. Pharmacists’ perceptions of MBA programs were evaluated through a survey of clinical preceptors affiliated with a school of pharmacy. Results. Seven US universities that offer an MBA program in pharmaceutical marketing and management were identified. Thirty-three percent of the 57 pharmacist preceptors who responded to the survey reported plans to pursue an MBA degree program. Respondents preferred MBA programs related to healthcare or pharmacy (66%) over general MBA programs (33%). Conclusion. An MBA in pharmaceutical marketing and management could provide pharmacists with advanced knowledge of the operational and strategic business aspects of pharmacy practice and give pharmacy graduates an advantage in an increasingly competitive job market.

    As the number of forensic science programs offered at higher education institutions rises, and more students express an interest in them, it is important to gain information regarding the offerings in terms of courses, equipment available to students, degree requirements, and other important aspects of the programs. A survey was conducted examining the existing bachelor's and master's forensic science programs in the U.S. Of the responding institutions, relatively few were, at the time of the survey, accredited by the forensic science Education Programs Accreditation Commission (FEPAC). In general, the standards of the responding programs vary considerably primarily in terms of their size and subjects coverage. While it is clear that the standards for the forensic science programs investigated are not homogeneous, the majority of the programs provide a strong science curriculum, faculties with advanced degrees, and interesting forensic-oriented courses. © 2010 American Academy of Forensic Sciences.

    We model the order statistics of network degrees of big data sets by a range of generalised beta distributions. A three parameter beta distribution due to Libby and Novick (1982) is shown to give the best overall fit for at least four big data sets. The fit of this distribution is significantly better than the fit suggested by Olhede and Wolfe (2012) across the whole range of order statistics for all four data sets.

    Purpose: The purpose of this study was to conduct a program evaluation of the University of Missouri-Kansas City Master of Science in Dental Hygiene Education Program (MSDH). This evaluation examined long-term outcomes in the context of stakeholders (the profession, the student, and the degree-granting institution).Methods: A mixed-methods approach was used to gather data from the 28 graduates from the MSDH program. An electronic questionnaire included both open- and closed-ended questions including demographic and practice data, and data related to alumni preparedness to reach their career goals. Virtual focus groups provided valuable insight into whether the program has achieved its goals, and prepared the graduates to meet their program competencies and future goals.Results: Out of a total of 28 individuals who have successfully completed the distance program (2001-2011), 19 participated in an online survey (67.8%). The majority of the participants (73.7%) participated in one of 3 focus groups. Sixty-three percent of the graduates are currently employed in dental hygiene education. Eighty-four percent of the respondents have published their research conducted while in the program, thereby contributing to the dental hygiene body of knowledge. Sixty-eight percent indicated that had the distance option not existed, they would not have been able to obtain their advanced degree in dental hygiene. Twenty-one percent of the respondents report either being currently enrolled in a doctoral program, or having completed a doctoral degree.Conclusion: These results suggest that the University of Missouri-Kansas City Master of Science in Dental Hygiene Education Program is meeting its goals from the perspective of all stakeholders and providing its graduates with access to education and educational resources to meet the program competencies and ultimately achieve their career goals.

  5. A proposal to establish master's in biomedical sciences degree programs in medical school environments.

    Most graduate schools associated with medical schools offer programs leading to the PhD degree but pay little attention to master's programs. This is unfortunate because many university graduates who are interested specifically in biomedical rather than pure science fields need further education before making decisions on whether to enter clinical, research, education, or business careers. Training for these students is done best in a medical school, rather than a graduate university, environment and by faculty who are engaged in research in the biomedical sciences. Students benefit from these programs by exploring career options they might not have previously considered while learning about disease-related subjects at the graduate level. Graduate faculty can also benefit by being compensated for their teaching with a portion of the tuition revenue, funds that can help run their laboratories and support other academic expenses. Faculty also may attract talented students to their labs and to their PhD programs by exposing them to a passion for research. The graduate school also benefits by collecting masters tuition revenue that can be used toward supporting PhD stipends. Six-year outcome data from the program at Newark show that, on completion of the program, most students enter educational, clinical, or research careers and that the graduate school has established a new and significant stream of revenue. Thus, the establishment of a master's program in biomedical sciences that helps students match their academic abilities with their career goals significantly benefits students as well as the graduate school and its faculty.

  6. Masters in nursing degrees: an evaluation of management and leadership outcomes using a retrospective pre-test design.

    2012-01-01

    The aim of the present study was to measure the leadership and management abilities of graduates who had completed a master's degree in nursing. A number of reports have recommended that leadership competencies be integrated into education programmes for nurses at a master's level. In spite of the growth in the number of graduates from higher degrees in nursing, there is a paucity of evidence on the management and leadership outcomes that develop as a result of undertaking a master's degree. A cross-sectional survey using a retrospective pre-test design was used to measure self-reported leadership and management outcomes from the graduates' educational programmes. Results found that graduates had gained significantly on their ability to change practice, communicate and work as part of a team and to problem solve as an outcome of completing a master's degree in nursing. Graduates make substantial gains in leadership and management capabilities as a consequence of their higher degree. These capabilities are necessary as nurses take the lead in many areas of healthcare. The masters in nursing degree now has a pivotal role in providing effective continuing education to the nursing profession; especially for those who occupy or intend to occupy senior positions within clinical, management or education branches of the profession. © 2011 Blackwell Publishing Ltd.

    Demographic changes have profoundly influenced the structure of present and future populations in terms of the number of older people requiring nursing care, the nature and settings of the nursing care provided, and finally, each individual, e. g., nursing care providers. The aim of the paper is to present the results of the EU Erasmus project GEROM, which, among other things, resulted in an on-line gerontological master's degree curriculum which is globally focused, flexible, innovative, diverse, contemporary and ICT-based. It focuses on meeting the needs of older people and their carers. An innovative aspect in the curriculum implementation is a virtual environment for clinical practice, enabling students to practice clinical and nursing interventions and diagnosing on-line, based on an adaptive, individualized and personalized blended-learning approach. During the pilot implementation of three randomly selected subjects, the students evaluated the program and were satisfied with both content and implementation.

    Full Text Available This descriptive, single, intrinsic case study seeks to answer the following questions: Why should business practitioners and educators work together in solving business problems? How are the business problems of companies handled in a master's degree programme in Finland? The case study is based on multiple sources of documents collected and developed during the ten years of the programme. It demonstrates that solving authentic business problems in a learning community of business practitioners, i.e. students, as well as educators, i.e. teachers and thesis advisors, leads to solutions that satisfy practitioners, educators, and the business community. This case is an example of how solving business problems together contributes to the better performance of businesses and a better society in Finland.

    Context  The debate over what the entry-level degree should be for athletic training has heightened. A comparison of retention and career-placement rates between bachelor's and master's degree professional athletic training programs may inform the debate. Objective  To compare the retention rates and career-placement rates of students in bachelor's and master's degree professional programs. Design  Cross-sectional study. Setting  Web-based survey. Patients or Other Participants  A total of 192 program directors (PDs) from bachelor's degree (n = 177) and master's degree (n = 15) professional programs. Intervention(s)  The PDs completed a Web-based survey. Main Outcome Measure(s)  We instructed the PDs to provide a retention rate and career-placement rate for the students in the programs they lead for each of the past 5 years. We also asked the PDs if they thought retention of students was a problem currently facing athletic training education. We used independent t tests to compare the responses between bachelor's and master's degree professional programs. Results  We found a higher retention rate for professional master's degree students (88.70% ± 9.02%, 95% confidence interval [CI] = 83.71, 93.69) than bachelor's degree students (80.98% ± 17.86%, 95% CI = 78.30, 83.66) (t25 = −2.86, P = .008, d = 0.55). Similarly, PDs from professional master's degree programs reported higher career-placement percentages (88.50% ± 10.68%, 95% CI = 82.33, 94.67) than bachelor's degree professional PDs (71.32% ± 18.47%, 95% CI = 68.54, 74.10) (t20 = −5.40, P training (χ21 = 0.720, P = .40, Φ = .061). Conclusions  Professional master's degree education appears to facilitate higher retention rates and greater career-placement rates in athletic training than bachelor's degree education. Professional socialization, program selectivity, and student commitment and motivation levels may help to explain the differences noted. PMID:26308497

  13. The dichotomy in degree correlation of biological networks.

    Directory of Open Access Journals (Sweden)

    Dapeng Hao

    Full Text Available Most complex networks from different areas such as biology, sociology or technology, show a correlation on node degree where the possibility of a link between two nodes depends on their connectivity. It is widely believed that complex networks are either disassortative (links between hubs are systematically suppressed or assortative (links between hubs are enhanced. In this paper, we analyze a variety of biological networks and find that they generally show a dichotomous degree correlation. We find that many properties of biological networks can be explained by this dichotomy in degree correlation, including the neighborhood connectivity, the sickle-shaped clustering coefficient distribution and the modularity structure. This dichotomy distinguishes biological networks from real disassortative networks or assortative networks such as the Internet and social networks. We suggest that the modular structure of networks accounts for the dichotomy in degree correlation and vice versa, shedding light on the source of modularity in biological networks. We further show that a robust and well connected network necessitates the dichotomy of degree correlation, suggestive of an evolutionary motivation for its existence. Finally, we suggest that a dichotomous degree correlation favors a centrally connected modular network, by which the integrity of network and specificity of modules might be reconciled.

  20. Importance of small-degree nodes in assortative networks with degree-weight correlations

    Ma, Sijuan; Feng, Ling; Monterola, Christopher Pineda; Lai, Choy Heng

    2017-10-01

    It has been known that assortative network structure plays an important role in spreading dynamics for unweighted networks. Yet its influence on weighted networks is not clear, in particular when weight is strongly correlated with the degrees of the nodes as we empirically observed in Twitter. Here we use the self-consistent probability method and revised nonperturbative heterogenous mean-field theory method to investigate this influence on both susceptible-infective-recovered (SIR) and susceptible-infective-susceptible (SIS) spreading dynamics. Both our simulation and theoretical results show that while the critical threshold is not significantly influenced by the assortativity, the prevalence in the supercritical regime shows a crossover under different degree-weight correlations. In particular, unlike the case of random mixing networks, in assortative networks, the negative degree-weight correlation leads to higher prevalence in their spreading beyond the critical transmissivity than that of the positively correlated. In addition, the previously observed inhibition effect on spreading velocity by assortative structure is not apparent in negatively degree-weight correlated networks, while it is enhanced for that of the positively correlated. Detailed investigation into the degree distribution of the infected nodes reveals that small-degree nodes play essential roles in the supercritical phase of both SIR and SIS spreadings. Our results have direct implications in understanding viral information spreading over online social networks and epidemic spreading over contact networks.

    2016-06-01

    INTRODUCTION The Department of General Practice and Primary Health Care at the University of Auckland is considering developing a Master of Primary Health Care (MPHC) programme. Masters level study entails considerable investment of both university and student time and money. AIM To explore the views of potential students and possible employers of future graduates to discover whether there is a market for such a programme and to inform the development of the programme. METHODS Semi-structured interviews were conducted with 30 primary health care stakeholders. Interviews were digitally recorded, transcribed and analysed using a general inductive approach to identify themes. FINDINGS Primary care practitioners might embark on MPHC studies to develop health management and leadership skills, to develop and/or enhance clinical skills, to enhance teaching and research skills, or for reasons of personal interest. Barriers to MPHC study were identified as cost and a lack of funding, time constraints and clinical workload. Study participants favoured inter-professional learning and a flexible delivery format. Pre-existing courses may already satisfy the post-graduate educational needs of primary care practitioners. Masters level study may be superfluous to the needs of the primary care workforce. CONCLUSIONS Any successful MPHC programme would need to provide value for PHC practitioner students and be unique. The postgraduate educational needs of New Zealand primary care practitioners may be already catered for. The international market for a MPHC programme is yet to be explored.

  6. Time-dependent degree-degree correlations in epileptic brain networks: from assortative to dissortative mixing

    Directory of Open Access Journals (Sweden)

    Christian eGeier

    2015-08-01

    Full Text Available We investigate the long-term evolution of degree-degree correlations (assortativity in functional brain networks from epilepsy patients. Functional networks are derived from continuous multi-day, multi-channel electroencephalographic data, which capture a wide range of physiological and pathophysiological activities. In contrast to previous studies which all reported functional brain networks to be assortative on average, even in case of various neurological and neurodegenerative disorders, we observe large fluctuations in time-resolved degree-degree correlations ranging from assortative to dissortative mixing. Moreover, in some patients these fluctuations exhibit some periodic temporal structure which can be attributed, to a large extent, to daily rhythms. Relevant aspects of the epileptic process, particularly possible pre-seizure alterations, contribute marginally to the observed long-term fluctuations. Nevertheless, our findings suggest that physiological and pathophysiological activity may modify functional brain networks in a different and process-specific way. We evaluate factors that possibly influence the long-term evolution of degree-degree correlations.

    2013-10-01

    In this theoretical study, we analyze quantum walks on complex networks, which model network-based processes ranging from quantum computing to biology and even sociology. Specifically, we analytically relate the average long-time probability distribution for the location of a unitary quantum walker to that of a corresponding classical walker. The distribution of the classical walker is proportional to the distribution of degrees, which measures the connectivity of the network nodes and underlies many methods for analyzing classical networks, including website ranking. The quantum distribution becomes exactly equal to the classical distribution when the walk has zero energy, and at higher energies, the difference, the so-called quantumness, is bounded by the energy of the initial state. We give an example for which the quantumness equals a Rényi entropy of the normalized weighted degrees, guiding us to regimes for which the classical degree-dependent result is recovered and others for which quantum effects dominate.

    2006-01-01

    A market-research study conducted in 2000 indicated a need for a degree program in food safety that would cover all aspects of the food system, from production to consumption. Despite this, such a program was not enthusiastically supported by employers, who feared losing their valued employees while they were enrolled in traditional on-campus graduate programs. A terminal professional degree was successfully created, offered, and modified over the succeeding five years. The innovative, non-traditional online program was developed to include a core curriculum and leadership training, with elective courses providing flexibility in specific areas of student interest or need. The resulting Professional Master of Science in Food Safety degree program provides a transdisciplinary approach for the protection of an increasingly complex food system and the improvement of public health. Enrollment in the program steadily increased in the first three years of delivery, with particular interest from industry and government employees. The curriculum provides a platform of subject material from which certificate programs, short-courses, seminars, workshops, and executive training programs may be delivered, not only to veterinarians but also to related food and health specialists. The program has fulfilled a need for adult learners to continue as working professionals in the workforce. The benefit to the employer and to society is an individual with enhanced knowledge and networking and leadership skills.

    This paper investigates master-slave exponential synchronization for a class of complex-valued memristor-based neural networks with time-varying delays via discontinuous impulsive control. Firstly, the master and slave complex-valued memristor-based neural networks with time-varying delays are translated to two real-valued memristor-based neural networks. Secondly, an impulsive control law is constructed and utilized to guarantee master-slave exponential synchronization of the neural networks. Thirdly, the master-slave synchronization problems are transformed into the stability problems of the master-slave error system. By employing linear matrix inequality (LMI) technique and constructing an appropriate Lyapunov-Krasovskii functional, some sufficient synchronization criteria are derived. Finally, a numerical simulation is provided to illustrate the effectiveness of the obtained theoretical results. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2010-04-01

    The introduction of the Bologna Process, in particular the implementation of a tiered structure of study programs and degrees, imposes quite some changes in most European higher education systems. The purpose of this article is to introduce some major points of the Bologna Process with regard to medical education in Germany and Europe and to reflect the process of the adoption of a two-cycle bachelor-master system in medicine. International positions and perspectives of professionals, students, and politicians are discussed which underline the complexity and dynamics of the whole process in contemporary higher education. A short reflection to key aspects of the two-cycle system, and student mobility is provided. Higher education in the whole health care sector may benefit from the Bologna objectives leading to a more permeable, comparable, and compatible medical education system across Europe.

    A growing number of institutions offer a master's degree in health communication to prepare individuals for applied work in the field, but there is very little literature on the career paths graduates pursue. The current study reports the results of a national survey that targeted the alumni of five institutions that offer the degree. Of the 522 total graduates to whom the survey was sent, 398 responded (76.2% response rate). Results show that the degree recipients have found employment in a wide variety of organizations across the country, including jobs within very prestigious organizations, such as the National Cancer Institute. Common job titles include manager, coordinator, communication associate/specialist, and program/project director. The most common job responsibilities include research activities, the development of health communication materials, project/program management, communication management, and social media/website management. The results also include stories of graduates across programs that illustrate details of career paths. The discussion of the findings addresses implications for career preparation, curriculum development, and advising.

  12. The diffusion of the distance Entomology Master's Degree Program at the University of Nebraska Lincoln: A descriptive case study

    Science.gov (United States)

    Hubbell, Jody M.

    This study explored three selected phases of Rogers' (1995) Diffusion of Innovations Theory to examine the diffusion process of the distance Entomology Master's Degree program at the University of Nebraska, Lincoln. A qualitative descriptive case study approach incorporated semi-structured interviews with individuals involved in one or more of the three stages: Development, Implementation, and Institutionalization. Documents and archival evidence were used to triangulate findings. This research analyzed descriptions of the program as it moved from the Development, to the Implementation, and finally, the Institutionalization stages of diffusion. Each respective stage was examined through open and axial coding. Process coding identified themes common to two or more diffusion stages, and explored the evolution of themes from one diffusion stage to the next. At a time of significant budget constraints, many departments were faced with the possibility of merger or dissolution. The Entomology Master's Degree Program evolved from being an entrepreneurial means to prevent departmental dissolution to eventually being viewed as a model for the development of similar programs across this university and other institutions of higher education. During this evolution, the program was reinvented to meet the broader needs of industry and a global student market. One finding not consistent with Rogers' model was that smaller, rather than larger, departmental size contributed to the success of the program. Within this small department, faculty members were able to share their experiences and knowledge with each other on a regular basis, which promoted greater acceptance of the distance program. How quality and rigor may be defined and measured was a key issue in each respective stage. In this specific case, quality and rigor was initially a comparison of on-campus and distance course content and then moved to program-based assessment and measures of student outcomes such as job

  13. Improved Degree Search Algorithms in Unstructured P2P Networks

    2012-01-01

    Full Text Available Searching and retrieving the demanded correct information is one important problem in networks; especially, designing an efficient search algorithm is a key challenge in unstructured peer-to-peer (P2P networks. Breadth-first search (BFS and depth-first search (DFS are the current two typical search methods. BFS-based algorithms show the perfect performance in the aspect of search success rate of network resources, while bringing the huge search messages. On the contrary, DFS-based algorithms reduce the search message quantity and also cause the dropping of search success ratio. To address the problem that only one of performances is excellent, we propose two memory function degree search algorithms: memory function maximum degree algorithm (MD and memory function preference degree algorithm (PD. We study their performance including the search success rate and the search message quantity in different networks, which are scale-free networks, random graph networks, and small-world networks. Simulations show that the two performances are both excellent at the same time, and the performances are improved at least 10 times.

    2015-12-01

    A cognitive radio (CR) network with energy harvesting (EH) is considered to improve both spectrum efficiency and energy efficiency. A hidden Markov model (HMM) is used to characterize the imperfect spectrum sensing process. In order to maximize the whole satisfaction degree (WSD) of the cognitive radio network, a tradeoff between the average throughput of the secondary user (SU) and the interference to the primary user (PU) is analyzed. We formulate the satisfaction degree optimization problem as a mixed integer nonlinear programming (MINLP) problem. The satisfaction degree optimization problem is solved by using differential evolution (DE) algorithm. The proposed optimization problem allows the network to adaptively achieve the optimal solution based on its required quality of service (Qos). Numerical results are given to verify our analysis.

  17. k-Degree Anonymity Model for Social Network Data Publishing

    Directory of Open Access Journals (Sweden)

    MACWAN, K. R.

    2017-11-01

    Full Text Available Publicly accessible platform for social networking has gained special attraction because of its easy data sharing. Data generated on such social network is analyzed for various activities like marketing, social psychology, etc. This requires preservation of sensitive attributes before it becomes easily accessible. Simply removing the personal identities of the users before publishing data is not enough to maintain the privacy of the individuals. The structure of the social network data itself reveals much information regarding its users and their connections. To resolve this problem, k-degree anonymous method is adopted. It emphasizes on the modification of the graph to provide at least k number of nodes that contain the same degree. However, this approach is not efficient on a huge amount of social data and the modification of the original data fails to maintain data usefulness. In addition to this, the current anonymization approaches focus on a degree sequence-based graph model which leads to major modification of the graph topological properties. In this paper, we have proposed an improved k-degree anonymity model that retain the social network structural properties and also to provide privacy to the individuals. Utility measurement approach for community based graph model is used to verify the performance of the proposed technique.

    Kähne, M.; Sokolov, I. M.; Rüdiger, S.

    2017-11-01

    We develop a statistical framework for studying recurrent networks with broad distributions of the number of synaptic links per neuron. We treat each group of neurons with equal input degree as one population and derive a system of equations determining the population-averaged firing rates. The derivation rests on an assumption of a large number of neurons and, additionally, an assumption of a large number of synapses per neuron. For the case of binary neurons, analytical solutions can be constructed, which correspond to steps in the activity versus degree space. We apply this theory to networks with degree-correlated topology and show that complex, multi-stable regimes can result for increasing correlations. Our work is motivated by the recent finding of subnetworks of highly active neurons and the fact that these neurons tend to be connected to each other with higher probability.

  20. Master stability functions reveal diffusion-driven instabilities in multi-layer networks

    Brechtel, Andreas; Ritterskamp, Daniel; Drossel, Barbara; Gross, Thilo

    2016-01-01

    Many systems in science and technology can be described as multilayer networks, which are known to exhibit phenomena such as catastrophic failure cascades and pattern-forming instabilities. A particular class of multilayer networks describes systems where different interacting copies of a local network exist in different spatial locations, including for instance regulatory and metabolic networks of identical cells and interacting habitats of ecological populations. Here, we show that such systems can be analyzed by a master stability function (MSF) approach, which reveals conditions for diffusion-driven instabilities (DDIs). We demonstrate the methodology on the example of state-of-the-art meta-foodweb models, where it reveals diffusion-driven instabilities that lead to localized dynamics and spatial patterns. This type of approach can be applied to a variety of systems from nature, science and engineering to aid the understanding and design of complex self-organizing systems.

    Background Over the past decade the profession of pharmacy has steadily evolved. The New Pharmacy Contract exposed pharmacists to a fundamental change in traditional pharmacy business models. Objective This study will consider whether community pharmacists, pharmacy undergraduates and academic staff within the United Kingdom believe it would be beneficial to incorporate a business management module within the Master of Pharmacy (MPharm) undergraduate degree along with potential mechanisms of delivery. Methods Further to ethical approval, the questionnaire was distributed to UK registered pharmacists (n=600), MPharm undergraduates (n=441) and academic staff at Liverpool John Moores University (n=44). The questions were formatted as multiple choice questions, Likert scales or the open answer type. On questionnaire completion and return, data were analysed using simple frequencies, cross tabulations and non-parametric techniques in the SPSS (v18). Results The majority of pharmacists (84.9%) confirmed that business skills affect their everyday responsibilities to a considerable extent. A high proportion of undergraduate students (92.8%) believed that business management skills will impact on their future role. In total, 64.3% of this cohort declared that if a module were introduced they would study it. The majority of staff (79%) agreed that business skills are gaining increased importance within the field of pharmacy. Conclusions Data suggest that business skills are of relevance to the practice of pharmacy. Appropriate staff to deliver the taught material would include business owners / lecturers and teaching practitioners covering topics including management, leadership, interpersonal skills and regulation. We suggest the inclusion of a business module with the MPharm degree would be of great value in preparing individuals for practice within a modern day healthcare setting. PMID:24155858

  4. Directed networks' different link formation mechanisms causing degree distribution distinction

    2016-11-01

    Within undirected networks, scientists have shown much interest in presenting power-law features. For instance, Barabási and Albert (1999) claimed that a common property of many large networks is that vertex connectivity follows scale-free power-law distribution, and in another study Barabási et al. (2002) showed power law evolution in the social network of scientific collaboration. At the same time, Jiang et al. (2011) discussed deviation from power-law distribution; others indicated that size effect (Bagrow et al., 2008), information filtering mechanism (Mossa et al., 2002), and birth and death process (Shi et al., 2005) could account for this deviation. Within directed networks, many authors have considered that outlinks follow a similar mechanism of creation as inlinks' (Faloutsos et al., 1999; Krapivsky et al., 2001; Tanimoto, 2009) with link creation rate being the linear function of node degree, resulting in a power-law shape for both indegree and outdegree distribution. Some other authors have made an assumption that directed networks, such as scientific collaboration or citation, behave as undirected, resulting in a power-law degree distribution accordingly (Barabási et al., 2002). At the same time, we claim (1) Outlinks feature different degree distributions than inlinks; where different link formation mechanisms cause the distribution distinctions, (2) in/outdegree distribution distinction holds for different levels of system decomposition; therefore this distribution distinction is a property of directed networks. First, we emphasize in/outlink formation mechanisms as causal factors for distinction between indegree and outdegree distributions (where this distinction has already been noticed in Barker et al. (2010) and Baxter et al. (2006)) within a sample network of OSS projects as well as Java software corpus as a network. Second, we analyze whether this distribution distinction holds for different levels of system decomposition: open

    The application of functional genomic analysis of breast cancer metastasis has led to the identification of a growing number of organ-specific metastasis genes, which often function in concert to facilitate different steps of the metastatic cascade. However, the gene regulatory network that controls the expression of these metastasis genes remains largely unknown. Here, we demonstrate a computational approach for the deconvolution of transcriptional networks to discover master regulators of breast cancer bone metastasis. Several known regulators of breast cancer bone metastasis such as Smad4 and HIF1 were identified in our analysis. Experimental validation of the networks revealed BACH1, a basic leucine zipper transcription factor, as the common regulator of several functional metastasis genes, including MMP1 and CXCR4. Ectopic expression of BACH1 enhanced the malignance of breast cancer cells, and conversely, BACH1 knockdown significantly reduced bone metastasis. The expression of BACH1 and its target genes was linked to the higher risk of breast cancer recurrence in patients. This study established BACH1 as the master regulator of breast cancer bone metastasis and provided a paradigm to identify molecular determinants in complex pathological processes. PMID:22875853

    2008-01-01

    Full Text Available Motivation: Proteins are essential macromolecules of life and thus understanding their function is of great importance. The number of functionally unclassified proteins is large even for simple and well studied organisms such as baker’s yeast. Methods for determining protein function have shifted their focus from targeting specific proteins based solely on sequence homology to analyses of the entire proteome based on protein-protein interaction (PPI networks. Since proteins interact to perform a certain function, analyzing structural properties of PPI networks may provide useful clues about the biological function of individual proteins, protein complexes they participate in, and even larger subcellular machines.Results: We design a sensitive graph theoretic method for comparing local structures of node neighborhoods that demonstrates that in PPI networks, biological function of a node and its local network structure are closely related. The method summarizes a protein’s local topology in a PPI network into the vector of graphlet degrees called the signature of the protein and computes the signature similarities between all protein pairs. We group topologically similar proteins under this measure in a PPI network and show that these protein groups belong to the same protein complexes, perform the same biological functions, are localized in the same subcellular compartments, and have the same tissue expressions. Moreover, we apply our technique on a proteome-scale network data and infer biological function of yet unclassified proteins demonstrating that our method can provide valuable guidelines for future experimental research such as disease protein prediction.Availability: Data is available upon request.

    Alvarez-Martínez, R.; Cocho, G.; Rodríguez, R. F.; Martínez-Mekler, G.

    2014-05-01

    Master equations for the evolution of complex networks with positive (birth) and negative (death) transition probabilities per unit time are analyzed. Explicit equations for the time evolution of the total number of nodes and for the relative node frequencies are given. It is shown that, in the continuous limit, the master equation reduces to a Fokker-Planck equation (FPE). The basic dynamical function for its stationary solution is the ratio between its drift and diffusion coefficients. When this ratio is approximated by partial fractions (Padé's approximants), a hierarchy of stationary solutions of the FPE is obtained analytically, which are expressed as an exponential times the product of powers of monomials and binomials. It is also shown that if the difference between birth and death transition probabilities goes asymptotically to zero, the exponential factor in the solution is absent. Fits to real complex network probability distribution functions are shown. Comparison with rank-ordered data shows that, in general, the value of this exponential factor is close to unity, evidencing crossovers among power-law scale invariant regimes which might be associated to an underlying criticality and are related to a generalization of the beta distribution. The time dependent solution is also obtained analytically in terms of hyper-geometric functions. It is also shown that the FPE has similarity solutions. The limitations of the approach here presented are also discussed.

    Full Text Available In this study, the control of four degree freedom robot arm has been realized with the computed torque control method.. It is usually required that the four jointed robot arm has high precision capability and good maneuverability for using in industrial applications. Besides, high speed working and external applied loads have been acting as important roles. For those purposes, the computed torque control method has been developed in a good manner that the robot arm can track the given trajectory, which has been able to enhance the feedback control together with fuzzy neural network control. The simulation results have proved that the computed torque control with the neural network has been so successful in robot control.

    This article describes the experiences of master students of nursing science in learning interpersonal communication competence through the simulation method. The exercises reflected challenging interactive situations in the field of health care. Few studies have been published on using the simulation method in the communication education of teachers, managers, and experts in this field. The aim of this study is to produce information which can be utilised in developing the simulation method to promote the interpersonal communication competence of master-level students of health sciences. This study used the qualitative, descriptive research method. At the Department of Nursing Science, the University of Eastern Finland, students major in nursing science specialise in nursing leadership and management, preventive nursing science, or nurse teacher education. Students from all three specialties taking the Challenging Situations in Speech Communication course participated (n=47). Essays on meaningful learning experiences collected using the critical incident technique, underwent content analysis. Planning of teaching, carrying out different stages of the simulation exercise, participant roles, and students' personal factors were central to learning interpersonal communication competence. Simulation is a valuable method in developing the interpersonal communication competence of students of health sciences at the masters' level. The methods used in the simulation teaching of emergency care are not necessarily applicable as such to communication education. The role of teacher is essential to supervising students' learning in simulation exercises. In the future, it is important to construct questions that help students to reflect specifically on communication. Copyright © 2014 Elsevier Ltd. All rights reserved.

The open answers given by students highlight the inter-university nature of the master's, the technological innovation used as major points, and the weaknesses in the management coordination or the duplicate contents as minor points. The external analysis is closely linked with the students' future jobs, their labour opportunities available to them after graduation. The innovative treatment of the data is exportable to the evaluation of programmes of other degrees because it allows the description linked to its characteristics and its design through the students' point of view.

  16. Single-frequency receivers as master permanent stations in GNSS networks: precision and accuracy of the positioning in mixed networks

    2015-04-01

    The use of GPS/GNSS instruments is a common practice in the world at both a commercial and academic research level. Since last ten years, Continuous Operating Reference Stations (CORSs) networks were born in order to achieve the possibility to extend a precise positioning more than 15 km far from the master station. In this context, the Geomatics Research Group of DIATI at the Politecnico di Torino has carried out several experiments in order to evaluate the achievable precision obtainable with different GNSS receivers (geodetic and mass-market) and antennas if a CORSs network is considered. This work starts from the research above described, in particular focusing the attention on the usefulness of single frequency permanent stations in order to thicken the existing CORSs, especially for monitoring purposes. Two different types of CORSs network are available today in Italy: the first one is the so called "regional network" and the second one is the "national network", where the mean inter-station distances are about 25/30 and 50/70 km respectively. These distances are useful for many applications (e.g. mobile mapping) if geodetic instruments are considered but become less useful if mass-market instruments are used or if the inter-station distance between master and rover increases. In this context, some innovative GNSS networks were developed and tested, analyzing the performance of rover's positioning in terms of quality, accuracy and reliability both in real-time and post-processing approach. The use of single frequency GNSS receivers leads to have some limits, especially due to a limited baseline length, the possibility to obtain a correct fixing of the phase ambiguity for the network and to fix the phase ambiguity correctly also for the rover. These factors play a crucial role in order to reach a positioning with a good level of accuracy (as centimetric o better) in a short time and with an high reliability. The goal of this work is to investigate about the

    Full Text Available This paper proposes two novel master-slave configurations that provide improvements in both control and communication aspects of teleoperation systems to achieve an overall improved performance in position control. The proposed novel master-slave configurations integrate modular control and communication approaches, consisting of a delay regulator to address problems related to variable network delay common to such systems, and a model tracking control that runs on the slave side for the compensation of uncertainties and model mismatch on the slave side. One of the configurations uses a sliding mode observer and the other one uses a modified Smith predictor scheme on the master side to ensure position transparency between the master and slave, while reference tracking of the slave is ensured by a proportional-differentiator type controller in both configurations. Experiments conducted for the networked position control of a single-link arm under system uncertainties and randomly varying network delays demonstrate significant performance improvements with both configurations over the past literature.

    Full Text Available This paper discusses the inclusion and use of ICTs in higher education at a postgraduate level; specifically in Master courses.  It presents some possibilities and opportunities for the use of technology in teaching mediation, including them as indispensable tools in the teaching and learning process. This is an exploratory and descriptive research that uses - as a source - both the review of the literature and a field research paper that is developed in an experience report format. The field research paper presents the experience of classes delivered in Master courses using Moodle as a complementary support platform to the lectures at two universities located in South America. Taking into account a methodological triangulation, collection techniques for the focus groups, questionnaires and participant observations were used as data. The paper concludes that the actual classes in the postgraduate courses may be made more dynamic with the use of technological tools that enable interaction before, during and after classroom activities, encouraging a pleasant and meaningful learning.

    The reliability of wireless sensor networks (WSNs) can be greatly affected by failures of sensor nodes due to energy exhaustion or the influence of brutal external environment conditions. Such failures seriously affect the data persistence and collection efficiency. Strategies based on network coding technology for WSNs such as LTCDS can improve the data persistence without mass redundancy. However, due to the bad intermediate performance of LTCDS, a serious 'cliff effect' may appear during the decoding period, and source data are hard to recover from sink nodes before sufficient encoded packets are collected. In this paper, the influence of coding degree distribution strategy on the 'cliff effect' is observed and the prioritized data storage and dissemination algorithm PLTD-ALPHA is presented to achieve better data persistence and recovering performance. With PLTD-ALPHA, the data in sensor network nodes present a trend that their degree distribution increases along with the degree level predefined, and the persistent data packets can be submitted to the sink node according to its degree in order. Finally, the performance of PLTD-ALPHA is evaluated and experiment results show that PLTD-ALPHA can greatly improve the data collection performance and decoding efficiency, while data persistence is not notably affected.

    2016-01-01

    Many naturally occurring networks have a power-law degree distribution as well as a non-zero degree correlation. Despite this, most studies analyzing the efficiency of immunization strategies in networks have concentrated only on power-law degree distribution and ignored degree correlation. This study looks specifically at the effect degree-correlation has on the efficiency of several immunization strategies in scale-free networks. Generally, we found that positive degree correlation raises the number of immunized individuals needed to stop the spread of the infection. Importantly, we found that in networks with positive degree correlation, immunization strategies that utilize knowledge of initial popularity actually perform worse on average than random immunization strategies.

    Athletes may have electrocardiogram (ECG) repolarization abnormalities during stress test suggestive for ischemia in the absence of ischemic coronary artery disease, often in a setting of myocardial septum hypertrophy. Global longitudinal strain (GLS) might be altered in these athletes compared to hypertensive patients with the same degree of septal thickness. About 735 consecutive athletes were screened for mandatory assessment of fitness to participate in competitive sports. At the stress test, 23 (19 M, 4 F) were found to have ECG repolarization abnormalities suggestive for ischemia in the presence of normal coronary vessels. They were matched to a control group of 23 hypertensive patients with no ECG abnormalities during stress test and the same degree of septal thickness. A transthoracic echocardiography for evaluation of global longitudinal strain (GLS) was performed. Interventricular septum thickness (IST) and relative wall thickness (RWT) were also calculated. A preserved ventricular function was seen in both groups (64 ± 8% in cases vs 60 ± 6% in controls, P = 0.42). IST and RWT were not significantly different. GLS was significantly lower in athletes vs hypertensive patients (-18.7 ± 2.5 vs -21.67 ± 0.27, P = 0.001). In athletes with septal hypertrophy and a positive stress test not associated to coronary disease, GLS is lower with respect to a population of hypertensive patient with the same degree of septal hypertrophy. Further investigations in a larger population are required to better define the potentiality of GLS in differentiating pathological vs physiological septum hypertrophy. © 2016 John Wiley & Sons A/S.

  10. Computing Assortative Mixing by Degree with the s-Metric in Networks Using Linear Programming

    2015-01-01

    Full Text Available Calculation of assortative mixing by degree in networks indicates whether nodes with similar degree are connected to each other. In networks with scale-free distribution high values of assortative mixing by degree can be an indication of a hub-like core in networks. Degree correlation has generally been used to measure assortative mixing of a network. But it has been shown that degree correlation cannot always distinguish properly between different networks with nodes that have the same degrees. The so-called s-metric has been shown to be a better choice to calculate assortative mixing. The s-metric is normalized with respect to the class of networks without self-loops, multiple edges, and multiple components, while degree correlation is always normalized with respect to unrestricted networks, where self-loops, multiple edges, and multiple components are allowed. The challenge in computing the normalized s-metric is in obtaining the minimum and maximum value within a specific class of networks. We show that this can be solved by using linear programming. We use Lagrangian relaxation and the subgradient algorithm to obtain a solution to the s-metric problem. Several examples are given to illustrate the principles and some simulations indicate that the solutions are generally accurate.

    Full Text Available Describing complex ecosystems as networks of interacting components has proved fruitful - revealing many distinctive patterns and dynamics of ecological systems. Of these patterns, three have often been brought up in literature, including species degree distribution, compartmentalization and nestedness, due largely to their implications for the functionality and stability of communities. Here, using 61 empirical antagonistic networks, we aim to settle the inconsistency in literature by (i fitting their node degree distributions to five different parametric models and identifying the one fits the best, (ii measuring the levels of nestedness and compartmentalization of these 61 networks and testing their significance using different null models, and (iii exploring how network connectance affects these three network architecture metrics. This research showed that most antagonistic networks do not display power law degree distributions and that resource species are generally uniformly distributed. We also clearly showed that the conclusion of whether a network is significantly compartmentalized or nested depends largely on the null model used.

    The emergent dynamics in networks of recurrently coupled spiking neurons depends on the interplay between single-cell dynamics and network topology. Most theoretical studies on network dynamics have assumed simple topologies, such as connections that are made randomly and independently with a fixed probability (Erdös-Rényi network) (ER) or all-to-all connected networks. However, recent findings from slice experiments suggest that the actual patterns of connectivity between cortical neurons are more structured than in the ER random network. Here we explore how introducing additional higher-order statistical structure into the connectivity can affect the dynamics in neuronal networks. Specifically, we consider networks in which the number of presynaptic and postsynaptic contacts for each neuron, the degrees, are drawn from a joint degree distribution. We derive mean-field equations for a single population of homogeneous neurons and for a network of excitatory and inhibitory neurons, where the neurons can have arbitrary degree distributions. Through analysis of the mean-field equations and simulation of networks of integrate-and-fire neurons, we show that such networks have potentially much richer dynamics than an equivalent ER network. Finally, we relate the degree distributions to so-called cortical motifs.

    To develop the next generation of translational investigators, New York University School of Medicine (NYUSOM) and the NYU-NYC Health and Hospitals Corporation Clinical and Translational Science Institute (NYU-HHC CTSI) developed the Master's of Science in Clinical Investigation dual-degree (MD/MSCI) program. This 5-year program dedicates 1 year to coursework and biomedical research, followed by a medical school/research overlap year, to prepare students for academic research careers. This paper details the MD/MSCI program's curriculum and approach to mentorship, describes the research/professional interests of students, and reports student productivity. In the first 4 years of the program (2010-2014) 20 students were matriculated; 7 (35%) were women, and 12 (60%) research projects were in surgical specialties. To date, 14 students have applied to residency, and half pursued surgical residency programs. Our students have produced 68 accepted abstracts, 15 abstracts in submission, 38 accepted papers, and 24 papers in submission. Despite the time-limited nature of this program, additional training in research design and implementation has promoted a high level of productivity. We conclude that dual-degree training in medicine and translational research is feasible for medical students and allows for meaningful participation in valuable projects. Follow-up is warranted to evaluate the academic trajectory of these students. © 2015 Wiley Periodicals, Inc.

    2017-11-01

    Full Text Available Objective: This pilot project, which was jointly conducted by a hospital and a university, describes the development of the Master's Degree Programme in Leadership in Medicine, a course designed to supplement medical specialty training. The aim of the pilot project is to demonstrate how hospital-based projects on personnel and organisational development undertaken under academic supervision can be used to increase leadership responsibility among doctors whose duties include providing initial and follow-on training and to professionalise medical specialty training as a leadership task. This need arose from the nationwide requirements and an internal audit regarding follow-on training. The version of the degree programme described below aims to further the personnel development of the participants in the field of didactics. Method: Each of the nine modules is made up of two classroom-based phases and one distance learning phase. The distance learning phase involves undertaking hospital-based projects on personnel and organisational development under academic supervision. The pilot phase participants were hospital doctors who, as part of their duties, hold leadership responsibility or are involved in the follow-on training of doctors.Results: The 17 participants successfully implemented more than 30 hospital-based projects during the distance learning phases of the nine modules. These projects included the development of medical specialty curricula, relevant didactic methods and evaluation design and were subsequently presented and subjected to reflection in interdisciplinary groups. The project presentation together with the project report were regarded as proof of competency. Conclusion: In addition to enhancing participant competency, the degree model described, which interlinks theory and practice, promotes organisational development through the implementation of projects undertaken under academic supervision. This has a double impact on the

    The increase of the use of the Internet networks favors the spread of viruses. In this paper, we studied the spread of viruses in the scale-free network with different topologies based on the Susceptible-Infected-External (SIE) model. It is found that the network structure influences the virus spreading. We have shown also that the nodes of high degree are more susceptible to infection than others. Furthermore, we have determined a critical maximum value of node degree (Kc), below which the network is more resistible and the computer virus cannot expand into the whole network. The influence of network size is also studied. We found that the network with low size is more effective to reduce the proportion of infected nodes.

    Neuronal circuits in the rodent barrel cortex are characterized by stable low firing rates. However, recent experiments show that short spike trains elicited by electrical stimulation in single neurons can induce behavioral responses. Hence, the underlying neural networks provide stability against internal fluctuations in the firing rate, while simultaneously making the circuits sensitive to small external perturbations. Here we studied whether stability and sensitivity are affected by the connectivity structure in recurrently connected spiking networks. We found that anti-correlation between the number of afferent (in-degree) and efferent (out-degree) synaptic connections of neurons increases stability against pathological bursting, relative to networks where the degrees were either positively correlated or uncorrelated. In the stable network state, stimulation of a few cells could lead to a detectable change in the firing rate. To quantify the ability of networks to detect the stimulation, we used a receiver operating characteristic (ROC) analysis. For a given level of background noise, networks with anti-correlated degrees displayed the lowest false positive rates, and consequently had the highest stimulus detection performance. We propose that anti-correlation in the degree distribution may be a computational strategy employed by sensory cortices to increase the detectability of external stimuli. We show that networks with anti-correlated degrees can in principle be formed by applying learning rules comprised of a combination of spike-timing dependent plasticity, homeostatic plasticity and pruning to networks with uncorrelated degrees. To test our prediction we suggest a novel experimental method to estimate correlations in the degree distribution.

    The central dogma of molecular biology states that ``information cannot be transferred back from protein to either protein or nucleic acid.'' However, this assumption is not exactly correct in most of the cases. There are a lot of feedback loops and interactions between different levels of systems. These types of interactions are hard to analyze due to the lack of data in the cellular level and probabilistic nature of interactions. Probabilistic models like Stochastic Master Equation (SME) or deterministic models like differential equations (DE) can be used to analyze these types of interactions. SME models based on chemical master equation (CME) can provide detailed representation of genetic regulatory system, but their use is restricted by the large data requirements and computational costs of calculations. The differential equations models on the other hand, have low calculation costs and much more adequate to generate control procedures on the system; but they are not adequate to investigate the probabilistic nature of interactions. In this work the success of the mapping between SME and DE is analyzed, and the success of a control policy generated by DE model with respect to SME model is examined.

    The complex network theory is applied to the study of urban road traffic network topology, and we constructed a new measure to characterize an urban road network. It is inspiring to quantify the interaction more appropriately between nodes in complex networks, especially in the field of traffic. The measure takes into account properties of lanes (e.g. number of lanes, width, traffic direction). As much, it is a more comprehensive measure in comparison to previous network measures. It can be used to grasp the features of urban street network more clearly. We applied this measure to the road network in Xiamen, China. Based on a standard method from statistical physics, we examined in more detail the distribution of this new measure and found that (1) due to the limitation of space geographic attributes, traditional research conclusions acquired by using the original definition of degree to study the primal approach modeled urban street network are not very persuasive; (2) both of the direction of the network connection and the degree's odd or even classifications need to be analyzed specifically; (3) the improved degree distribution presents obvious hierarchy, and hierarchical values conform to the power-law distribution, and correlation of our new measure shows some significant segmentation of the urban road network.

    An innovative training program to provide clinical research training for clinicians was created in 1979 at the University of Pennsylvania School of Medicine, now the Perelman School of Medicine. The program's principal and continuing aim is to provide trainees mentored experiences and the training needed to become skilled independent investigators able to conduct clinical research and develop academic careers as independent clinical investigators.The authors identify the vision that led to the creation of the master of science in clinical epidemiology (MSCE) degree program and describe today's training program, including administration, oversight, participating faculty, and trainees. They also describe the program's core curriculum, elective options, seminars on ongoing research, training in the responsible conduct of research, professional development activities, and the development and completion of a closely mentored clinical research project.Approximately 35 new trainees enter the two- to three-year program annually. Funding is provided primarily by National Institutes of Health-funded training programs and supplemented by private industry, private foundations, and employee-based benefits. More than 500 individuals have received or are currently receiving training through the MSCE program. A large percentage of former trainees maintain full-time positions in academic medicine today.The authors identify some challenges that have been met and insights regarding funding, faculty, trainees, and curriculum. Ongoing challenges include recruiting trainees from some selected highly paid, procedure-oriented specialties, maintaining sufficient mentors for the continually increasing numbers of trainees, and distinguishing applicants who truly desire a primary research career from others.

    Full Text Available ABSTRACT The general aim of this study was identifying the motivational level of students in Accounting and Economics regarding the search for a stricto sensu graduate degree. Also, it sought to determine the variables that significantly influence the motivation of these individuals. Having the Self-Determination Theory as a basis, a questionnaire was prepared resorting to the Academic Motivation Scale developed by Vallerand, Pelletier, Blais, Brière, Senécal, and Vallières (1992, and translated into Portuguese by Sobral (2003. The database contains observations of 173 university students from public institutions in Minas Gerais, Brazil, which provided courses in Accounting and Economics. The methodological procedure consisted in conducting a non-parametric test of mean values for the Motivation Self-Determination Index (MSI of students, in calculating the correlations between the MSI and individual characteristics of students, and finally in estimating multiple linear regressions. Research results indicated that students in Accounting showed no difference regarding the motivational level when compared to students in Economics. It was also possible to notice that women, older students, scientific initiation scholarship holders, those from lower socioeconomic backgrounds, and those whose mothers have higher educational level tend to have a rather self-determined motivation. Additionally, it was found that insertion into the labor market increases self-determined motivation to pursue a stricto sensu Master's degree only in the case of students in Accounting. The research was limited to the fact that the sample only included students of public education institutions from Minas Gerais. For future research, it is suggested that the procedures of this study be replicated in privet institution and in different states.

    Information processing in the brain crucially depends on the topology of the neuronal connections. We investigate how the topology influences the response of a population of leaky integrate-and-fire neurons to a stimulus. We devise a method to calculate firing rates from a self-consistent system of equations taking into account the degree distribution and degree correlations in the network. We show that assortative degree correlations strongly improve the sensitivity for weak stimuli and propose that such networks possess an advantage in signal processing. We moreover find that there exists an optimum in assortativity at an intermediate level leading to a maximum in input/output mutual information.

    Full Text Available A method based on coarse-graining to construct a directed weighted complex network which models the transformation of the trading data of an individual stock is introduced. The degree (strength distribution of derived network follows a power-law. A moderated regression equation with interaction effects of average return and out-degree (in-degree on out-strength (in-strength is established. Moreover, we found that the differences of nodes affect the network’s structure and average return level impacts nodes’ eigenvector centrality and pagerank, significantly.

  8. Comprehensive Weighted Clique Degree Ranking Algorithms and Evolutionary Model of Complex Network

    2016-01-01

    Full Text Available This paper analyses the degree ranking (DR algorithm, and proposes a new comprehensive weighted clique degree ranking (CWCDR algorithms for ranking importance of nodes in complex network. Simulation results show that CWCDR algorithms not only can overcome the limitation of degree ranking algorithm, but also can find important nodes in complex networks more precisely and effectively. To the shortage of small-world model and BA model, this paper proposes an evolutionary model of complex network based on CWCDR algorithms, named CWCDR model. Simulation results show that the CWCDR model accords with power-law distribution. And compare with the BA model, this model has better average shortest path length, and clustering coefficient. Therefore, the CWCDR model is more consistent with the real network.

  9. Modularity and anti-modularity in networks with arbitrary degree distribution

    Science.gov (United States)

    2010-01-01

    Background Much work in systems biology, but also in the analysis of social network and communication and transport infrastructure, involves an in-depth analysis of local and global properties of those networks, and how these properties relate to the function of the network within the integrated system. Most often, systematic controls for such networks are difficult to obtain, because the features of the network under study are thought to be germane to that function. In most such cases, a surrogate network that carries any or all of the features under consideration, while created artificially and in the absence of any selective pressure relating to the function of the network being studied, would be of considerable interest. Results Here, we present an algorithmic model for growing networks with a broad range of biologically and technologically relevant degree distributions using only a small set of parameters. Specifying network connectivity via an assortativity matrix allows us to grow networks with arbitrary degree distributions and arbitrary modularity. We show that the degree distribution is controlled mainly by the ratio of node to edge addition probabilities, and the probability for node duplication. We compare topological and functional modularity measures, study their dependence on the number and strength of modules, and introduce the concept of anti-modularity: a property of networks in which nodes from one functional group preferentially do not attach to other nodes of that group. We also investigate global properties of networks as a function of the network's growth parameters, such as smallest path length, correlation coefficient, small-world-ness, and the nature of the percolation phase transition. We search the space of networks for those that are most like some well-known biological examples, and analyze the biological significance of the parameters that gave rise to them.

    2005-06-01

    Using the scientific definition of gossip, an ancient and ubiquitous phenomenon of the social networks, we present our preliminary study and its results on how to measure the networks based on dissemination of connections and information. We try to accurately calculate the gossip-effects in networks with our hypothesis of "three degrees of inclusion". Our preliminary study on the subject of "three degrees of inclusion" gives latency to a very important property of social networks. Observing the human communication of closely knit social groups we came to the conclusion that the human networks are based on not more than three degrees of links. Taking the strong human ties into account our research indicates that whoever is on the fourth degree rarely counts as an in-group member. Our close friend's close friend's close friend — that is about the farthest — three steps — our network can reach out when it comes to telling a story or asking for a favor. Up to now no investigations have been performed to see whether the effects of gossip lead to the phase transition of the content of network's self-organizing communication. Our conclusion is that the gossip-effect must be considered as the prefactor of the news and opinions diffusion and dynamics at the social level.

    Species establish different interactions (e.g. antagonistic, mutualistic) with multiple species, forming multilayer ecological networks. Disentangling network co-structure in multilayer networks is crucial to predict how biodiversity loss may affect the persistence of multispecies assemblages. Existing methods to analyse multilayer networks often fail to consider network co-structure. We present a new method to evaluate the modular co-structure of multilayer networks through the assessment of species degree co-distribution and network module composition. We focus on modular structure because of its high prevalence among ecological networks. We apply our method to two Lepidoptera-plant networks, one describing caterpillar-plant herbivory interactions and one representing adult Lepidoptera nectaring on flowers, thereby possibly pollinating them. More than 50% of the species established either herbivory or visitation interactions, but not both. These species were over-represented among plants and lepidopterans, and were present in most modules in both networks. Similarity in module composition between networks was high but not different from random expectations. Our method clearly delineates the importance of interpreting multilayer module composition similarity in the light of the constraints imposed by network structure to predict the potential indirect effects of species loss through interconnected modular networks.

    Supersymmetric gauge theories have an important but perhaps under-appreciated notion of a master space, which controls the full moduli space. For world-volume theories of D-branes probing a Calabi-Yau singularity X the situation is particularly illustrative. In the case of one physical brane, the master space F is the space of F-terms and a particular quotient thereof is X itself. We study various properties of F which encode such physical quantities as Higgsing, BPS spectra, hidden global symmetries, etc. Using the plethystic program we also discuss what happens at higher number N of branes. This letter is a summary and some extensions of the key points of a longer companion paper arXiv:0801.1585.

    2014-11-01

    The effects of white noise and global coupling strength on the maximum degree of synchronization in complex networks are explored. We perform numerical simulations of generic oscillator models with both linear and non-linear coupling functions on a broad spectrum of network topologies. The oscillator models include the Fitzhugh-Nagumo model, the Izhikevich model and the Kuramoto phase oscillator model. The network topologies range from regular, random and highly modular networks to scale-free and small-world networks, with both directed and undirected edges. We then study the dependency of the maximum degree of synchronization on the global coupling strength and the noise intensity. We find a general scaling of the synchronizability, and quantify its validity by fitting a regression model to the numerical data.

    Network studies have played a central role for understanding many systems in nature - e.g., physical, biological, and social. So far, much of the focus has been the statistics of networks in isolation. Yet, many networks in the world are coupled to each other. Recently, we considered this issue, in the context of two interacting social networks. In particular, We studied networks with two different preferred degrees, modeling, say, introverts vs. extroverts, with a variety of ``rules for engagement.'' As a first step towards an analytically accessible theory, we restrict our attention to an ``extreme scenario'': The introverts prefer zero contacts while the extroverts like to befriend everyone in the society. In this ``maximally frustrated'' system, the degree distributions, as well as the statistics of cross-links (between the two groups), can depend sensitively on how a node (individual) creates/breaks its connections. The simulation results can be reasonably well understood in terms of an approximate theory.

  15. Label Propagation with α-Degree Neighborhood Impact for Network Community Detection

    2014-01-01

    Full Text Available Community detection is an important task for mining the structure and function of complex networks. In this paper, a novel label propagation approach with α-degree neighborhood impact is proposed for efficiently and effectively detecting communities in networks. Firstly, we calculate the neighborhood impact of each node in a network within the scope of its α-degree neighborhood network by using an iterative approach. To mitigate the problems of visiting order correlation and convergence difficulty when updating the node labels asynchronously, our method updates the labels in an ascending order on the α-degree neighborhood impact of all the nodes. The α-degree neighborhood impact is also taken as the updating weight value, where the parameter impact scope α can be set to a positive integer. Experimental results from several real-world and synthetic networks show that our method can reveal the community structure in networks rapidly and accurately. The performance of our method is better than other label propagation based methods.

    2017-10-01

    Full Text Available This article aims to provide new results about the intraday degree sequence distribution considering phone call network graph evolution in time. More specifically, it tackles the following problem. Given a large amount of landline phone call data records, what is the best way to summarize the distinct number of calling partners per client per day? In order to answer this question, a series of undirected phone call network graphs is constructed based on data from a local telecommunication source in Albania. All network graphs of the series are simplified. Further, a longitudinal temporal study is made on this network graphs series related to the degree distributions. Power law and log-normal distribution fittings on the degree sequence are compared on each of the network graphs of the series. The maximum likelihood method is used to estimate the parameters of the distributions, and a Kolmogorov–Smirnov test associated with a p-value is used to define the plausible models. A direct distribution comparison is made through a Vuong test in the case that both distributions are plausible. Another goal was to describe the parameters’ distributions’ shape. A Shapiro-Wilk test is used to test the normality of the data, and measures of shape are used to define the distributions’ shape. Study findings suggested that log-normal distribution models better the intraday degree sequence data of the network graphs. It is not possible to say that the distributions of log-normal parameters are normal.

    This case-study compared traditional, face-to-face classroom-based teaching with asynchronous online learning and teaching methods in two sets of students undertaking a problem-based learning module in the multilevel and exploratory factor analysis of longitudinal data as part of a Masters degree in Public Health at Maastricht University. Students were allocated to one of the two study variants on the basis of their enrolment status as full-time or part-time students. Full-time students (n = 11) followed the classroom-based variant and part-time students (n = 12) followed the online asynchronous variant which included video recorded lectures and a series of asynchronous online group or individual SPSS activities with synchronous tutor feedback. A validated student motivation questionnaire was administered to both groups of students at the start of the study and a second questionnaire was administered at the end of the module. This elicited data about student satisfaction with the module content, teaching and learning methods, and tutor feedback. The module coordinator and problem-based learning tutor were also interviewed about their experience of delivering the experimental online variant and asked to evaluate its success in relation to student attainment of the module's learning outcomes. Student examination results were also compared between the two groups. Asynchronous online teaching and learning methods proved to be an acceptable alternative to classroom-based teaching for both students and staff. Educational outcomes were similar for both groups, but importantly, there was no evidence that the asynchronous online delivery of module content disadvantaged part-time students in comparison to their full-time counterparts.

    2016-01-01

    Full Text Available Due to the existence of a large number of redundant data in the process of covering multiple targets, the effective coverage of monitored region decreases, causing the network to consume more energy. To solve this problem, this paper proposes a multitarget k-degree coverage preservation protocol. Firstly, the affiliation between the sensor nodes and target nodes is established in the network model; meanwhile the method used to calculate the coverage expectation value of the monitored region is put forward; secondly, in the aspect of the network energy conversion, use scheduling mechanisms on the sensor nodes to balance the network energy and achieve different network coverage quality with energy conversion between different nodes. Finally, simulation results show that NMCP can improve the network lifetime by effectively reducing the number of active nodes to meet certain coverage requirements.

    The design of immunization strategies is an extremely important issue for disease or computer virus control and prevention. In this paper, we propose an improved local immunization strategy based on node's clustering which was seldom considered in the existing immunization strategies. The main aim of the proposed strategy is to iteratively immunize the node which has a high connectivity and a low clustering coefficient. To validate the effectiveness of our strategy, we compare it with two typical local immunization strategies on both real and artificial networks with a high degree of clustering. Simulations on these networks demonstrate that the performance of our strategy is superior to that of two typical strategies. The proposed strategy can be regarded as a compromise between computational complexity and immune effect, which can be widely applied in scale-free networks of high clustering, such as social network, technological networks and so on. In addition, this study provides useful hints for designing optimal immunization strategy for specific network.

    We propose a simple stochastic model describing the position-dependent ball-passing network in football games. In this network, a player on a certain area in the divided fields is a node, and a pass between two nodes corresponds to an edge. Our model is characterized by the consecutive choice of a node dependent on its intrinsic fitness. We derive the explicit expression of the degree distribution, and find that the derived distribution reproduces the real data quit well.

    The game of Go has long been viewed as the most challenging of classic games for artificial intelligence owing to its enormous search space and the difficulty of evaluating board positions and moves. Here we introduce a new approach to computer Go that uses 'value networks' to evaluate board positions and 'policy networks' to select moves. These deep neural networks are trained by a novel combination of supervised learning from human expert games, and reinforcement learning from games of self-play. Without any lookahead search, the neural networks play Go at the level of state-of-the-art Monte Carlo tree search programs that simulate thousands of random games of self-play. We also introduce a new search algorithm that combines Monte Carlo simulation with value and policy networks. Using this search algorithm, our program AlphaGo achieved a 99.8% winning rate against other Go programs, and defeated the human European Go champion by 5 games to 0. This is the first time that a computer program has defeated a human professional player in the full-sized game of Go, a feat previously thought to be at least a decade away.

    2015-01-01

    The financial crisis illustrated the need for a functional understanding of systemic risk in strongly interconnected financial structures. Dynamic processes on complex networks being intrinsically difficult to model analytically, most recent studies of this problem have relied on numerical simulations. Here we report analytical results in a network model of interbank lending based on directly relevant financial parameters, such as interest rates and leverage ratios. We obtain a closed-form formula for the "critical degree" (the number of creditors per bank below which an individual shock can propagate throughout the network), and relate failures distributions to network topologies, in particular scalefree ones. Our criterion for the onset of contagion turns out to be isomorphic to the condition for cooperation to evolve on graphs and social networks, as recently formulated in evolutionary game theory. This remarkable connection supports recent calls for a methodological rapprochement between finance and ecology.

    During the alternating day-night cycle, people have differing behavior and hence different connection patterns-such as going to work or home, shopping and so on. Hence, the true topological structure of human contact networks are not only time-varying but also exhibit certain distribution regularity. In this paper, we will investigate epidemic spreading on time-varying human contact networks, which follow one degree distribution during daytime, but another at night. Based on SIS (susceptible/infected/susceptible) propagation mechanism, we study the epidemic threshold of this network with alternating distributions. A surprising result is that for the discrete-time case the epidemic threshold is determined only by the first moments of the two alternating degree distributions, if the degree of each node is constant for all nights. A similar result is valid for the continuous-time case if the duration is sufficiently small. This work shows that the spreading dynamics of time-varying networks with alternating distributions is completely different from the widely studied case of static spreading networks.

    Whole brain weighted connectivity networks were extracted from high resolution diffusion MRI data of 14 healthy volunteers. A statistically robust technique was proposed for the removal of questionable connections. Unlike most previous studies our methods are completely adapted for networks with arbitrary weights. Conventional statistics of these weighted networks were computed and found to be comparable to existing reports. After a robust fitting procedure using multiple parametric distributions it was found that the weighted node degree of our networks is best described by the normal distribution, in contrast to previous reports which have proposed heavy tailed distributions. We show that post-processing of the connectivity weights, such as thresholding, can influence the weighted degree asymptotics. The clustering coefficients were found to be distributed either as gamma or power-law distribution, depending on the formula used. We proposed a new hierarchical graph clustering approach, which revealed that the brain network is divided into a regular base-2 hierarchical tree. Connections within and across this hierarchy were found to be uncommonly ordered. The combined weight of our results supports a hierarchically ordered view of the brain, whose connections have heavy tails, but whose weighted node degrees are comparable.

    States form defensive military alliances to enhance their security in the face of potential or realized interstate conflict. The network of these international alliances is increasingly interconnected, now linking most of the states in a complex web of ties. These alliances can be used both as a tool for securing cooperation and to foster peace between direct partners. However, do indirect connections-such as the ally of an ally or even further out in the alliance network-result in lower probabilities of conflict? We investigate the extent to which military alliances produce peace between states that are not directly allied. We find that the peacemaking horizon of indirect alliances extends through the network up to three degrees of separation. Within this horizon of influence, a lack of decay in the effect of degrees of distance indicates that alliances do not diminish with respect to their ability to affect peace regardless of whether or not the states in question are directly allied. Beyond the three-degree horizon of influence, we observe a sharp decline in the effect of indirect alliances on bilateral peace. Further investigation reveals that the community structure of the alliance network plays a role in establishing this horizon, but the effects of indirect alliances are not spurious to the community structure.

  12. S-curve networks and a new method for estimating degree distributions of complex networks

    CERN Document Server

    Guo, Jin-Li

    2010-01-01

    In the study of complex networks almost all theoretical models are infinite growth, but the size of actual networks is finite. According to statistics from the China Internet IPv4 addresses, we propose a forecasting model by using S curve (Logistic curve). The growing trend of IPv4 addresses in China is forecasted. There are some reference value for optimizing the distribution of IPv4 address resource and the development of IPv6. Based on the laws of IPv4 growth, that is, the bulk growth and the finitely growing limit, we propose a finite network model with the bulk growth. The model is called S-curve network. Analysis demonstrates that the analytic method based on uniform distributions (i.e., Barab\\'asi-Albert method) is not suitable for the network. We develop a new method to predict the growth dynamics of the individual nodes, and use this to calculate analytically the connectivity distribution and the scaling exponents. The analytical result agrees with the simulation well, obeying an approximately power-...

    Previously many studies on online social networks simply analyze the static topology in which the friend relationship once established, then the links and nodes will not disappear, but this kind of static topology may not accurately reflect temporal interactions on online social services. In this study, we define four types of users and interactions in the interaction (dynamic) network. We found that active, disappeared, new and super nodes (users) have obviously different strength distribution properties and this result also can be revealed by the degree characteristics of the unweighted interaction and friendship (static) networks. However, the active, disappeared, new and super links (interactions) only can be reflected by the strength distribution in the weighted interaction network. This result indicates the limitation of the static topology data on analyzing social network evolutions. In addition, our study uncovers the approximately stable statistics for the dynamic social network in which there are a large variation for users and interaction intensity. Our findings not only verify the correctness of our definitions, but also helped to study the customer churn and evaluate the commercial value of valuable customers in online social networks.

    We propose a simple stochastic model describing the position-dependent ball-passing network in football (soccer) games. In this network, a player in a certain area in a divided field is a node, and a pass between two nodes corresponds to an edge. Our stochastic process model is characterized by the consecutive choice of a node depending on its intrinsic fitness. We derive an explicit expression for the degree distribution and find that the derived distribution reproduces that for actual data reasonably well.

    Full Text Available In view of the applications of artificial neural networks in economic and financial forecasting, a stochastic time strength function is introduced in the backpropagation neural network model to predict the fluctuations of stock price changes. In this model, stochastic time strength function gives a weight for each historical datum and makes the model have the effect of random movement, and then we investigate and forecast the behavior of volatility degrees of returns for the Chinese stock market indexes and some global market indexes. The empirical research is performed in testing the prediction effect of SSE, SZSE, HSI, DJIA, IXIC, and S&P 500 with different selected volatility degrees in the established model.

  17. On the Degrees of Freedom for Multi-Hop Wireless Networks under Layered TDD Constraint

    2014-05-01

    Full Text Available Degrees of freedom (DoF of a network build a new scaling law characterizing the scalability of capacity at high signal-to-noise region. In this paper, we extend our recent work from cascaded network to the general K-hop layered network. The main framework is based on the assumption of layered TDD, where all nodes at each layer work with the same on/off status. By this approach we decompose the DoF analysis into two steps: 1 apply the result of cascaded networks; 2 analyze / design the transmission of each hop. The upper and lower bounds on DoF are deduced. By viewing the network as cascaded X channels, we find an inner bound of the DoF region, applicable to many message topologies. The detail of message splitting is demonstrated. Finally ultimate analysis shows if the number of antennas/nodes at each relay layer goes to infinity, the lower bound reaches the upper bound. As a by-product, when K > 2 the network can alleviate the effect of TDD with the increase of relay antennas/nodes.

    Central dogma of molecular biology states that ``information cannot be transferred back from protein to either protein or nucleic acid''. However, this assumption is not exactly correct in most of the cases. There are a lot of feedback loops and interactions between different levels of systems. These types of interactions are hard to analyze due to the lack of cell level data and probabilistic - nonlinear nature of interactions. Several models widely used to analyze and simulate these types of nonlinear interactions. Stochastic Master Equation (SME) models give probabilistic nature of the interactions in a detailed manner, with a high calculation cost. On the other hand Probabilistic Boolean Network (PBN) models give a coarse scale picture of the stochastic processes, with a less calculation cost. Differential Equation (DE) models give the time evolution of mean values of processes in a highly cost effective way. The understanding of the relations between the predictions of these models is important to understand the reliability of the simulations of genetic regulatory networks. In this work the success of the mapping between SME, PBN and DE models is analyzed and the accuracy and affectivity of the control policies generated by using PBN and DE models is compared.

    Full Text Available La mise en place de cours qui alternent le face-à-face et la distance sont loin d'être monnaie courante. Si l'on en croit (Charlier et al., 2004, les premiers dispositifs de ce type seraient apparus en France aux alentours de 1997, alors qu'ils étaient pressentis comme une réponse possible au tout à distance. Les potentialités de ces dispositifs en termes d'innovation pédagogique commencent cependant à être mises en avant, notamment dans un ouvrage récent paru aux Etats-Unis (Graham, 2006. Deux questions se posent alors : quels avantages présente chacune des modalités de formation et comment faire en sorte qu'elles soient complémentaires. C'est à ces questions que j'essaie de répondre dans cet article à partir d'une expérience d'hybridation d'un cours de première année de master de sciences du langage intitulé : "technologies de l'information et de la communication pour l'enseignement / apprentissage du FLE".Classes combining face to face and distance teaching are far from being widespread. According to (Charlier et al., 2004, the first environments of this kind have appeared in France around 1997, as they were perceived as a possible alternative to distance teaching exclusively. In terms of pedagogic innovation however, the potentialities of these environments begin to be emphasised, in particular in a recent book published in the United States (Graham, 2006. Two issues must then be considered: what are the respective advantages of these two training modes and how can we make them complementary. In this article, I will try to answer these questions, through the analysis of an experimental hybrid module being offered on the first year of the Masters: "Information technology and communication for teaching/learning of French as a foreign language".

  20. Network growth with arbitrary initial conditions: Degree dynamics for uniform and preferential attachment

    Fotouhi, Babak; Rabbat, Michael G.

    2013-12-01

    This paper provides time-dependent expressions for the expected degree distribution of a given network that is subject to growth. We consider both uniform attachment, where incoming nodes form links to existing nodes selected uniformly at random, and preferential attachment, where probabilities are assigned proportional to the degrees of the existing nodes. We consider the cases of single and multiple links being formed by each newly introduced node. The initial conditions are arbitrary, that is, the solution depends on the degree distribution of the initial graph which is the substrate of the growth. Previous work in the literature focuses on the asymptotic state, that is, when the number of nodes added to the initial graph tends to infinity, rendering the effect of the initial graph negligible. Our contribution provides a solution for the expected degree distribution as a function of time, for arbitrary initial condition. Previous results match our results in the asymptotic limit. The results are discrete in the degree domain and continuous in the time domain, where the addition of new nodes to the graph are approximated by a continuous arrival rate.

    Maintaining privacy in network data publishing is a major challenge. This is because known characteristics of individuals can be used to extract new information about them. Recently, researchers have developed privacy methods based on k-anonymity and l-diversity to prevent re-identification or sensitive label disclosure through certain structural information. However, most of these studies have considered only structural information and have been developed for undirected networks. Furthermore, most existing approaches rely on generalization and node clustering so may entail significant information loss as all properties of all members of each group are generalized to the same value. In this paper, we introduce a framework for protecting sensitive attribute, degree (the number of connected entities), and relationships, as well as the presence of individuals in directed social network data whose nodes contain attributes. First, we define a privacy model that specifies privacy requirements for the above private information. Then, we introduce the technique of Ambiguity in Social Network data (ASN) based on anatomy, which specifies how to publish social network data. To employ ASN, individuals are partitioned into groups. Then, ASN publishes exact values of properties of individuals of each group with common group ID in several tables. The lossy join of those tables based on group ID injects uncertainty to reconstruct the original network. We also show how to measure different privacy requirements in ASN. Simulation results on real and synthetic datasets demonstrate that our framework, which protects from four types of private information disclosure, preserves data utility in tabular, topological and spectrum aspects of networks at a satisfactory level.

    Detailed connection maps of human and nonhuman brains are being generated with new technologies, and graph metrics have been instrumental in understanding the general organizational features of these structures. Neural networks appear to have small world properties: they have clustered regions, while maintaining integrative features such as short average pathlengths. We captured the structural characteristics of clustered networks with short average pathlengths through our own variable, System Difference (SD), which is computationally simple and calculable for larger graph systems. SD is a Jaccardian measure generated by averaging all of the differences in the connection patterns between any two nodes of a system. We calculated SD over large random samples of matrices and found that high SD matrices have a low average pathlength and a larger number of clustered structures. SD is a measure of degree distribution with high SD matrices maximizing entropic properties. Phi (Φ), an information theory metric that assesses a system's capacity to integrate information, correlated well with SD - with SD explaining over 90% of the variance in systems above 11 nodes (tested for 4 to 13 nodes). However, newer versions of Φ do not correlate well with the SD metric. The new network measure, SD, provides a link between high entropic structures and degree distributions as related to small world properties.

    Full Text Available The creation and development of scientific knowledge has, as its basis, the social relations of researchers, (Kuhn, 1978. Such scientific collaboration can be identified through the analysis of social networks (Smith, 1958; Price, 1966; Katz, 1993, Newman, 2001; Barabási, 2003; Godechot e Mariot, 2004. Based on this premise, this paper aims to identify and analyze the structural dynamics of relationships among the masters-level graduate programs in the area of Accounting Sciences in Brazil, from the perspective of the social networks evidenced in the examination committees established for candidates to the Masters degree in this area. To this end, a descriptive study was carried out using Social Network Analysis to identify the structure of the scientific and academic network established by the collaboration of professors of graduate programs in Accounting Sciences in the examination committees of Masters candidates. Two hundred and forty-one (241 professors were identified from eighteen (18 programs who took part in one thousand and two (1002 Masters' examinations from 2002 to 2010. It was found that the creation of new graduate studies programs in the area and the insertion of new teachers was decisive in the increase of collaboration on Masters' examination committees. In light of this evidence, results point to a future scenario of the accounting field characterized by the evolution of scientific and academic collaboration, confirming that scientific knowledge is created and developed by social relations of actors involved in the area.

    Depressive symptoms are one of the main reasons for seeking psychological help. Shorter interventions using briefly trained therapists could offer a solution to the ever-rising need for early and easily applicable psychological treatments. The current study examines the effectiveness of a four-session Acceptance and Commitment Therapy (ACT) based treatment for self-reported depressive symptoms administered by Masters level psychology students. This paper reports the effectiveness of a brief intervention compared to a waiting list control (WLC) group. Participants were randomized into two groups: ACT (n = 28) and waiting list (n = 29). Long-term effects were examined using a 6-month follow-up. The treatment group's level of depressive symptoms (Beck Depression Inventory) decreased by an average of 47%, compared to an average decrease of 4% in the WLC group. Changes in psychological well-being in the ACT group were better throughout, and treatment outcomes were maintained after 6 months. The posttreatment "between-group" and follow-up "with-in group" effect sizes (Cohen's d) were large to medium for depressive symptoms and psychological flexibility. The results support the brief ACT-based intervention for sub-clinical depressive symptoms when treatment was conducted by briefly trained psychology students. It also contributes to the growing body of evidence on brief ACT-based treatments and inexperienced therapists.

    Master of Public Health (MPH) training programmes were developed worldwide in response to the crisis in human resources for health. To determine whether the MPH programme at the selected rural-based university in South Africa enabled students to achieve the MPH core competencies relevant for Lower Middle Income Countries. The study was carried out at a rural-based University in South Africa. The target population was the 2011 first-year cohort of MPH students who by the beginning of 2014 had just completed their coursework. A quantitative cross-sectional descriptive research design was adapted. Eighty-five students were randomly selected to participate in the study. A structured questionnaire comprising seven competency clusters was developed. The selected students completed a self-administered questionnaire. Only those students who signed consent forms participated in this study. The questionnaire was tested for construct validity and reliability using 10 students with similar characteristics to those sampled for the study. Microsoft Excel software was used to analyse the data descriptively in terms of frequency and percentages. The students were confident of their competencies regarding public health science skills. Amongst these were analytical assessment, communication, community and intersectorial competencies as well as ethics. However, the students lacked confidence in contextsensitive issues, planning and management, research and development, and leadership competencies. Yet the latter is the backbone of public health practice. There is a need for revamping public health curricula. In this respect, a follow-up study that builds a deeper understanding of the subject is needed.

The databases used in the study have been gained from the Hungarian Graduate Career Tracking Survey conducted in 2012 as well as from public regional data sources of the Hungarian Central Statistical Office. Relying on these databases independent t-tests, variance and regression analyses are performed to 1 identify the starting wage premium of those graduated at master‟s level compared to others owning only a bachelor‟s degree in the regions of Hungary, and to 2 define the role of regional factors (economic development, labour market indicators, demographic variables in the wage differences. Major conclusions of the study are that 1 obtaining a master‟s degree forecasts a significantly higher starting wage in most of the observed geographical areas, but 2 the size of this positive contribution significantly differs region by region (partly depending on economic and labour market factors.

    Full Text Available Investors in stock market are usually greedy during bull markets and scared during bear markets. The greed or fear spreads across investors quickly. This is known as the herding effect, and often leads to a fast movement of stock prices. During such market regimes, stock prices change at a super-exponential rate and are normally followed by a trend reversal that corrects the previous overreaction. In this paper, we construct an indicator to measure the magnitude of the super-exponential growth of stock prices, by measuring the degree of the price network, generated from the price time series. Twelve major international stock indices have been investigated. Error diagram tests show that this new indicator has strong predictive power for financial extremes, both peaks and troughs. By varying the parameters used to construct the error diagram, we show the predictive power is very robust. The new indicator has a better performance than the LPPL pattern recognition indicator.

    2016-01-01

    In a range of citation networks, the in-degree distributions boast time-periodicity---the distributions of citations per article published each year present similar scale-free tails. This phenomenon can be regarded as a consequence of the emergence of hot topics and the existence of the "burst" phenomenon. With this inference considered, a geometric model based on our previous study is established, in which the sizes of the influence zones of nodes follow the same power-law distribution and decrease with their ages. The model successfully reproduces the time-periodicity of the in-degree distributions of the empirical data, and accounts for the presence of citation burst as well. Moreover, a reasonable explanation for the emergence of the scale-free tails by regarding the citation behavior between articles as a "yes/no" experiment is presented. The model can also predict the time-periodicity of the local clustering coefficients, which indicates that the model is a good tool in researches on the evolutionary me...

    Full Text Available Zeolites are microporous aluminosilicate/silicate crystalline materials with three-dimensional tetrahedral configuration. In this study, the degree of crystallinity of the synthesized Linde Type A (LTA zeolite, which is the main indicator of its quality/purity is tried to be modeled. Effect of crystallization time, temperature, molar ratio of the synthesis gel on the relative crystallinity of the LTA zeolites is investigated using artificial neural networks. Our experimental observations and some data collected from literature have been used for adjusting the parameters of the proposed model and evaluating its performance. It has been observed that two-layer perceptron network with eight hidden neurons is the most accurate approach for the considered task. The designed model predicts the experimental datasets with a mean square error of 3.99 × 10-6, absolute average relative deviation of 8.69 %, and regression coefficient of 0.9596. The proposed model can decrease the required time and number of experiments to evaluate the extent of crystallinity of the LTA zeolites.

    Many complex networks in natural and social phenomena have often been characterized by heavy-tailed degree distributions. However, due to rapidly growing size of network data and concerns on privacy issues about using these data, it becomes more difficult to analyze complete data sets. Thus, it is crucial to devise effective and efficient estimation methods for heavy tails of degree distributions in large-scale networks only using local information of a small fraction of sampled nodes. Here we propose a tail-scope method based on local observational bias of the friendship paradox. We show that the tail-scope method outperforms the uniform node sampling for estimating heavy tails of degree distributions, while the opposite tendency is observed in the range of small degrees. In order to take advantages of both sampling methods, we devise the hybrid method that successfully recovers the whole range of degree distributions. Our tail-scope method shows how structural heterogeneities of large-scale complex networks can be used to effectively reveal the network structure only with limited local information.

    At present, the European Higher Education Area (EHEA) emphasizes the importance of collaborative learning in University education. Previous studies have found evidence to support collaborative activities; however, none have analyzed the influence of contact networks among students on their engagement and performance. This paper reports an intervention with nursing degree students aimed at facilitating an interdependent network to promote engagement and improve academic performance. The intervention was based on recording a video during a case study. The variables analyzed were network centrality, engagement and performance. The UCINET program was used to analyse social networks. The results showed a more cohesive network after the intervention and a high level of academic performance. The use of contact networks among students could be used as an academic strategy to build bridges between students in the classroom and even between these and students in other classrooms or centres.

    The volume of data that will be produced by new-generation surveys requires automatic classification methods to select and analyse sources. Indeed, this is the case for the search for strong gravitational lenses, where the population of the detectable lensed sources is only a very small fraction of the full source population. We apply for the first time a morphological classification method based on a Convolutional Neural Network (CNN) for recognizing strong gravitational lenses in 255 deg2 of the Kilo Degree Survey (KiDS), one of the current-generation optical wide surveys. The CNN is currently optimized to recognize lenses with Einstein radii ≳1.4 arcsec, about twice the r-band seeing in KiDS. In a sample of 21 789 colour-magnitude selected luminous red galaxies (LRGs), of which three are known lenses, the CNN retrieves 761 strong-lens candidates and correctly classifies two out of three of the known lenses. The misclassified lens has an Einstein radius below the range on which the algorithm is trained. We down-select the most reliable 56 candidates by a joint visual inspection. This final sample is presented and discussed. A conservative estimate based on our results shows that with our proposed method it should be possible to find ∼100 massive LRG-galaxy lenses at z ≲ 0.4 in KiDS when completed. In the most optimistic scenario, this number can grow considerably (to maximally ∼2400 lenses), when widening the colour-magnitude selection and training the CNN to recognize smaller image-separation lens systems.

    We develop the stochastic, chemical master equation as a unifying approach to the dynamics of biochemical reaction systems in a mesoscopic volume under a living environment. A living environment provides a continuous chemical energy input that sustains the reaction system in a nonequilibrium steady state with concentration fluctuations. We discuss the linear, unimolecular single-molecule enzyme kinetics, phosphorylation-dephosphorylation cycle (PdPC) with bistability, and network exhibiting oscillations. Emphasis is paid to the comparison between the stochastic dynamics and the prediction based on the traditional approach based on the Law of Mass Action. We introduce the difference between nonlinear bistability and stochastic bistability, the latter has no deterministic counterpart. For systems with nonlinear bistability, there are three different time scales: (a) individual biochemical reactions, (b) nonlinear network dynamics approaching to attractors, and (c) cellular evolution. For mesoscopic systems with size of a living cell, dynamics in (a) and (c) are stochastic while that with (b) is dominantly deterministic. Both (b) and (c) are emergent properties of a dynamic biochemical network; We suggest that the (c) is most relevant to major cellular biochemical processes such as epi-genetic regulation, apoptosis, and cancer immunoediting. The cellular evolution proceeds with transitions among the attractors of (b) in a "punctuated equilibrium" manner.

    An electronic nose (EN) based on an array of 10 metal oxide semiconductor sensors was used, jointly with an artificial neural network (ANN), to predict coffee roasting degree. The flavor release evolution and the main physicochemical modifications (weight loss, density, moisture content, and surface color: L*, a*), during the roasting process of coffee, were monitored at different cooking times (0, 6, 8, 10, 14, 19 min). Principal component analysis (PCA) was used to reduce the dimensionality of sensors data set (600 values per sensor). The selected PCs were used as ANN input variables. Two types of ANN methods (multilayer perceptron [MLP] and general regression neural network [GRNN]) were used in order to estimate the EN signals. For both neural networks the input values were represented by scores of sensors data set PCs, while the output values were the quality parameter at different roasting times. Both the ANNs were able to well predict coffee roasting degree, giving good prediction results for both roasting time and coffee quality parameters. In particular, GRNN showed the highest prediction reliability. Actually the evaluation of coffee roasting degree is mainly a manned operation, substantially based on the empirical final color observation. For this reason it requires well-trained operators with a long professional skill. The coupling of e-nose and artificial neural networks (ANNs) may represent an effective possibility to roasting process automation and to set up a more reproducible procedure for final coffee bean quality characterization. © 2012 Institute of Food Technologists®

    Full Text Available In present study I proposed a method for generating biological networks based on power-law (p(x=x^(-a and exponential-law (p(x=e^(-ax distribution functions. Given the parameter of power-law or exponential-law distribution function, a, the algorithm generates an expected frequency distribution according to the given parameter, thereafter creates an adjacency matrix in which (practical frequency distribution of node degrees matches the expected frequency distribution. The results showed that power-law distribution function performs much better than exponential-law distribution function in generating networks. Using the revised algorithm, tumor related networks (pathways are simulated and predicted. The results prove that the algorithm is overall effective in predicting network links (14.6%-21.2%of correctly predicted links against 0.1%-3.4% of that for random assignments. Matlab codes of the algorithms are given also.

    The financial crisis illustrated the need for a functional understanding of systemic risk in strongly interconnected financial structures. Dynamic processes on complex networks being intrinsically difficult to model analytically, most recent studies of this problem have relied on numerical simulations. Here we report analytical results in a network model of interbank lending based on directly relevant financial parameters, such as interest rates and leverage ratios. We obtain a closed-form formula for the “critical degree” (the number of creditors per bank below which an individual shock can propagate throughout the network), and relate failures distributions to network topologies, in particular scalefree ones. Our criterion for the onset of contagion turns out to be isomorphic to the condition for cooperation to evolve on graphs and social networks, as recently formulated in evolutionary game theory. This remarkable connection supports recent calls for a methodological rapprochement between finance and ecology. PMID:26207631

    2017-03-01

    Full Text Available The article provides the theoretical foundations of building a graph model of the survivability of a fuzzy network in terms of the theory of fuzzy sets of the second type. The possibility and the correctness of generalizing the concept of the fuzzy graph in terms of presentation of the set of n-ary relations for an arbitrary finite n ? ? have been studied. Definitions of the fuzzy hypergraph have been introduced. The natural spread of the concept of the degree of survivability on the hypergraph has been displayed. The main cases of reducing the survivability of the fuzzy oriented graph have been specified. Analyzes of the task of increasing the degree of survivability of a fuzzy transportation network by the criterion of least cost and its interpretation in the matters of air transportation have been carried out. The authors suggest a modification of the known algorithm that allows to increase the sum value of the functions of membership of the fuzzy graph edges so that its survivability can reach the desired value. It has been substantiated that, using the considered theoretical foundations, the proposed algorithm allows to enhance the degree of survivability of the fuzzy network of airports up to the specified level.

    Full Text Available In order to realize the predicting and positioning of short-term load inflection point, this paper made reference to related research in the field of computer image recognition. It got a load sharp degree sequence by the transformation of the original load sequence based on the algorithm of sharp degree. Then this paper designed a forecasting model based on the chaos theory and RBF neural network. It predicted the load sharp degree sequence based on the forecasting model to realize the positioning of short-term load inflection point. Finally, in the empirical example analysis, this paper predicted the daily load point of a region using the actual load data of the certain region to verify the effectiveness and applicability of this method. Prediction results showed that most of the test sample load points could be accurately predicted.

    Sexual dimorphism is one of the most pervasive and diverse features of animal morphology, physiology, and behavior. Despite the generality of the phenomenon itself, the mechanisms controlling how sex is determined differ considerably among various organismic groups, have evolved repeatedly and independently, and the underlying molecular pathways can change quickly during evolution. Even within closely related groups of organisms for which the development of gonads on the morphological, histological, and cell biological level is undistinguishable, the molecular control and the regulation of the factors involved in sex determination and gonad differentiation can be substantially different. The biological meaning of the high molecular plasticity of an otherwise common developmental program is unknown. While comparative studies suggest that the downstream effectors of sex-determining pathways tend to be more stable than the triggering mechanisms at the top, it is still unclear how conserved the downstream networks are and how all components work together. After many years of stasis, when the molecular basis of sex determination was amenable only in the few classical model organisms (fly, worm, mouse), recently, sex-determining genes from several animal species have been identified and new studies have elucidated some novel regulatory interactions and biological functions of the downstream network, particularly in vertebrates. These data have considerably changed our classical perception of a simple linear developmental cascade that makes the decision for the embryo to develop as male or female, and how it evolves. © 2015 The Authors.

  11. Modeling Fluid’s Dynamics with Master Equations in Ultrametric Spaces Representing the Treelike Structure of Capillary Networks

    Directory of Open Access Journals (Sweden)

    Andrei Khrennikov

    2016-07-01

    Full Text Available We present a new conceptual approach for modeling of fluid flows in random porous media based on explicit exploration of the treelike geometry of complex capillary networks. Such patterns can be represented mathematically as ultrametric spaces and the dynamics of fluids by ultrametric diffusion. The images of p-adic fields, extracted from the real multiscale rock samples and from some reference images, are depicted. In this model the porous background is treated as the environment contributing to the coefficients of evolutionary equations. For the simplest trees, these equations are essentially less complicated than those with fractional differential operators which are commonly applied in geological studies looking for some fractional analogs to conventional Euclidean space but with anomalous scaling and diffusion properties. It is possible to solve the former equation analytically and, in particular, to find stationary solutions. The main aim of this paper is to attract the attention of researchers working on modeling of geological processes to the novel utrametric approach and to show some examples from the petroleum reservoir static and dynamic characterization, able to integrate the p-adic approach with multifractals, thermodynamics and scaling. We also present a non-mathematician friendly review of trees and ultrametric spaces and pseudo-differential operators on such spaces.

    Myelin loss is a severe pathological hallmark common to a number of neurodegenerative diseases, including multiple sclerosis (MS). Demyelination in the central nervous system appears in the form of lesions affecting both white and gray matter structures. The functional consequences of demyelination on neuronal network and brain function are not well understood. Current therapeutic strategies for ameliorating the course of such diseases usually focus on promoting remyelination, but the effectiveness of these approaches strongly depends on the timing in relation to the disease state. In this study, we sought to characterize the time course of sensory and behavioral alterations induced by de- and remyelination to establish a rational for the use of remyelination strategies. By taking advantage of animal models of general and focal demyelination, we tested the consequences of myelin loss on the functionality of the auditory thalamocortical system: a well-studied neuronal network consisting of both white and gray matter regions. We found that general demyelination was associated with a permanent loss of the tonotopic cortical organization in vivo, and the inability to induce tone-frequency-dependent conditioned behaviors, a status persisting after remyelination. Targeted, focal lysolecithin-induced lesions in the white matter fiber tract, but not in the gray matter regions of cortex, were fully reversible at the morphological, functional and behavioral level. These findings indicate that remyelination of white and gray matter lesions have a different functional regeneration potential, with the white matter being able to regain full functionality while cortical gray matter lesions suffer from permanently altered network function. Therefore therapeutic interventions aiming for remyelination have to consider both region- and time-dependent strategies. Copyright © 2016 The Authors. Published by Elsevier Inc.

    In this work, we study an evolutionary prisoner's dilemma game (PDG) on Barabási-Albert scale-free networks with limited player interactions, and explore the effect of interaction style and degree on cooperation. The results show that high-degree preference interaction, namely the most applicable interaction in the real world, is less beneficial for emergence of cooperation on scale-free networks than random interaction. Besides, cooperation on scale-free networks is enhanced with the increase of interaction degree regardless whether the interaction is high-degree preference or random. If the interaction degree is very low, the cooperation level on scale-free networks is much lower than that on regular ring networks, which is against the common belief that scale-free networks must be more beneficial for cooperation. Our analysis indicates that the interaction relations, the strategy and the game payoff of high-connectivity players play important roles in the evolution of cooperation on scale-free networks. A certain number of interactions are necessary for scale-free networks to exhibit strong capability of facilitating cooperation. Our work provides important insight for members on how to interact with others in a social organization.

  17. Increasing signal specificity of the TOL network of Pseudomonas putida mt-2 by rewiring the connectivity of the master regulator XylR.

    Directory of Open Access Journals (Sweden)

    Aitor de Las Heras

    Full Text Available Prokaryotic transcription factors (TFs that bind small xenobiotic molecules (e.g., TFs that drive genes that respond to environmental pollutants often display a promiscuous effector profile for analogs of the bona fide chemical signals. XylR, the master TF for expression of the m-xylene biodegradation operons encoded in the TOL plasmid pWW0 of Pseudomonas putida, responds not only to the aromatic compound but also, albeit to a lesser extent, to many other aromatic compounds, such as 3-methylbenzylalcohol (3MBA. We have examined whether such a relaxed regulatory scenario can be reshaped into a high-capacity/high-specificity regime by changing the connectivity of this effector-sensing TF within the rest of the circuit rather than modifying XylR structure itself. To this end, the natural negative feedback loop that operates on xylR transcription was modified with a translational attenuator that brings down the response to 3MBA while maintaining the transcriptional output induced by m-xylene (as measured with a luxCDABE reporter system. XylR expression was then subject to a positive feedback loop in which the TF was transcribed from its own target promoters, each known to hold different input/output transfer functions. In the first case (xylR under the strong promoter of the upper TOL operon, Pu, the reporter system displayed an increased transcriptional capacity in the resulting network for both the optimal and the suboptimal XylR effectors. In contrast, when xylR was expressed under the weaker Ps promoter, the resulting circuit unmistakably discriminated m-xylene from 3MBA. The non-natural connectivity engineered in the network resulted both in a higher promoter activity and also in a much-increased signal-to-background ratio. These results indicate that the working regimes of given genetic circuits can be dramatically altered through simple changes in the way upstream transcription factors are self-regulated by positive or negative feedback loops.

  18. Equal opportunity for low-degree network nodes: a PageRank-based method for protein target identification in metabolic graphs.

    Biological network data, such as metabolic-, signaling- or physical interaction graphs of proteins are increasingly available in public repositories for important species. Tools for the quantitative analysis of these networks are being developed today. Protein network-based drug target identification methods usually return protein hubs with large degrees in the networks as potentially important targets. Some known, important protein targets, however, are not hubs at all, and perturbing protein hubs in these networks may have several unwanted physiological effects, due to their interaction with numerous partners. Here, we show a novel method applicable in networks with directed edges (such as metabolic networks) that compensates for the low degree (non-hub) vertices in the network, and identifies important nodes, regardless of their hub properties. Our method computes the PageRank for the nodes of the network, and divides the PageRank by the in-degree (i.e., the number of incoming edges) of the node. This quotient is the same in all nodes in an undirected graph (even for large- and low-degree nodes, that is, for hubs and non-hubs as well), but may differ significantly from node to node in directed graphs. We suggest to assign importance to non-hub nodes with large PageRank/in-degree quotient. Consequently, our method gives high scores to nodes with large PageRank, relative to their degrees: therefore non-hub important nodes can easily be identified in large networks. We demonstrate that these relatively high PageRank scores have biological relevance: the method correctly finds numerous already validated drug targets in distinct organisms (Mycobacterium tuberculosis, Plasmodium falciparum and MRSA Staphylococcus aureus), and consequently, it may suggest new possible protein targets as well. Additionally, our scoring method was not chosen arbitrarily: its value for all nodes of all undirected graphs is constant; therefore its high value captures importance in the

    High-grade serous ovarian carcinoma (HGS-OvCa) has the lowest survival rate among all gynecologic cancers and is hallmarked by a high degree of heterogeneity. The Cancer Genome Atlas network has described a gene expression-based molecular classification of HGS-OvCa into Differentiated, Mesenchymal, Immunoreactive and Proliferative subtypes. However, the biological underpinnings and regulatory mechanisms underlying the distinct molecular subtypes are largely unknown. Here we showed that tumor-infiltrating stromal cells significantly contributed to the assignments of Mesenchymal and Immunoreactive clusters. Using reverse engineering and an unbiased interrogation of subtype regulatory networks, we identified the transcriptional modules containing master regulators that drive gene expression of Mesenchymal and Immunoreactive HGS-OvCa. Mesenchymal master regulators were associated with poor prognosis, while Immunoreactive master regulators positively correlated with overall survival. Meta-analysis of 749 HGS-OvCa expression profiles confirmed that master regulators as a prognostic signature were able to predict patient outcome. Our data unraveled master regulatory programs of HGS-OvCa subtypes with prognostic and potentially therapeutic relevance, and suggested that the unique transcriptional and clinical characteristics of ovarian Mesenchymal and Immunoreactive subtypes could be, at least partially, ascribed to tumor microenvironment.

    A method is disclosed based on precision X-Y stages that are stacked. Attached to arms projecting from each X-Y stage are a set of two axis gimbals. Attached to the gimbals is a rod, which provides motion along the axis of the rod and rotation around its axis. A dual-planar apparatus that provides six degrees of freedom of motion precise to within microns of motion. Precision linear stages along with precision linear motors, encoders, and controls provide a robotics system. The motors can be remotized by incorporating a set of bellows on the motors and can be connected through a computer controller that will allow one to be a master and the other one to be a slave. Position information from the master can be used to control the slave. Forces of interaction of the slave with its environment can be reflected back to the motor control of the master to provide a sense of force sensed by the slave. Forces import onto the master by the operator can be fed back into the control of the slave to reduce the forces required to move it.

  5. Simultaneous stability and sensitivity in model cortical networks is achieved through anti-correlations between the in- and out-degree of connectivity

    Directory of Open Access Journals (Sweden)

    Juan Carlos Vasquez

    2013-11-01

    Full Text Available Neuronal networks in rodent barrel cortex are characterized by stable low baseline firing rates. However, they are sensitive to the action potentials of single neurons as suggested by recent single-cell stimulation experiments that report quantifiable behavioral responses in response to short spike trains elicited in single neurons. Hence, these networks are stable against internally generated fluctuations in firing rate but at the same time remain sensitive to similarly-sized externally induced perturbations. We investigated stability and sensitivity in a simple recurrent network of stochastic binary neurons and determined numerically the effects of correlation between the number of afferent (‘in-degree’ and efferent (‘out-degree’ connections in neurons. The key advance reported in this work is that anti-correlation between in-/out-degree distributions increased the stability of the network in comparison to networks with no correlation or positive correlations, while being able to achieve the same level of sensitivity. The experimental characterization of degree distributions is difficult because all presynaptic and postsynaptic neurons have to be identified and counted. We explored whether the statistics of network motifs, which requires the characterization of connections between small subsets of neurons, could be used to detect evidence for degree anti-correlations. We find that the sample frequency of the 3-neuron ‘ring’ motif (1→2→3→1, can be used to detect degree anti-correlation for sub-networks of size 30 using about 50 samples, which is of significance because the necessary measurements are achievable experimentally in the near future.Taken together, we hypothesize that barrel cortex networks exhibit degree anti-correlations and specific network motif statistics.

    Since 2016 the USA National Phenology Network (USA-NPN; www.usanpn.org) has produced and delivered daily maps and short-term forecasts of accumulated growing degree days and spring onset dates at fine spatial scale for the conterminous United States. Because accumulated temperature is a strong driver of phenological transitions in plants and animals, including leaf-out, flowering, fruit ripening, and migration, these data products have utility for a wide range of natural resource planning and management applications, including scheduling invasive species and pest detection and control activities, determining planting dates, anticipating allergy outbreaks and planning agricultural harvest dates. The USA-NPN is a national-scale program that supports scientific advancement and decision-making by collecting, storing, and sharing phenology data and information. We will be expanding the suite of gridded map products offered by the USA-NPN to include predictive species-specific maps of phenological transitions in plants and animals at fine spatial and temporal resolution in the future. Data products, such as the gridded maps currently produced by the USA-NPN, inherently contain uncertainty and error arising from multiple sources, including error propagated forward from underlying climate data and from the models implemented. As providing high-quality, vetted data in a transparent way is central to the USA-NPN, we aim to identify and report the sources and magnitude of uncertainty and error in gridded maps and forecast products. At present, we compare our real-time gridded products to independent, trustworthy data sources, such as the Climate Reference Network, on a daily basis and report Mean Absolute Error and bias through an interactive online dashboard.

  10. A new algorithm to find fuzzy Hamilton cycle in a fuzzy network using adjacency matrix and minimum vertex degree.

    Science.gov (United States)

    Nagoor Gani, A; Latha, S R

    2016-01-01

    A Hamiltonian cycle in a graph is a cycle that visits each node/vertex exactly once. A graph containing a Hamiltonian cycle is called a Hamiltonian graph. There have been several researches to find the number of Hamiltonian cycles of a Hamilton graph. As the number of vertices and edges grow, it becomes very difficult to keep track of all the different ways through which the vertices are connected. Hence, analysis of large graphs can be efficiently done with the assistance of a computer system that interprets graphs as matrices. And, of course, a good and well written algorithm will expedite the analysis even faster. The most convenient way to quickly test whether there is an edge between two vertices is to represent graphs using adjacent matrices. In this paper, a new algorithm is proposed to find fuzzy Hamiltonian cycle using adjacency matrix and the degree of the vertices of a fuzzy graph. A fuzzy graph structure is also modeled to illustrate the proposed algorithms with the selected air network of Indigo airlines.

  11. An improved correlation to predict molecular weight between crosslinks based on equilibrium degree of swelling of hydrogel networks.

    Jimenez-Vergara, Andrea C; Lewis, John; Hahn, Mariah S; Munoz-Pinto, Dany J

    2017-07-17

    Accurate characterization of hydrogel diffusional properties is of substantial importance for a range of biotechnological applications. The diffusional capacity of hydrogels has commonly been estimated using the average molecular weight between crosslinks (Mc ), which is calculated based on the equilibrium degree of swelling. However, the existing correlation linking Mc and equilibrium swelling fails to accurately reflect the diffusional properties of highly crosslinked hydrogel networks. Also, as demonstrated herein, the current model fails to accurately predict the diffusional properties of hydrogels when polymer concentration and molecular weight are varied simultaneously. To address these limitations, we evaluated the diffusional properties of 48 distinct hydrogel formulations using two different photoinitiator systems, employing molecular size exclusion as an alternative methodology to calculate average hydrogel mesh size. The resulting data were then utilized to develop a revised correlation between Mc and hydrogel equilibrium swelling that substantially reduces the limitations associated with the current correlation. © 2017 Wiley Periodicals, Inc.

    Toh, Kok-Aun; Tsoi, Mun-Fie

    2008-11-01

    The dire need of some schools to boost the academic performance of their students inevitably rests with their ability to attract highly qualified teachers. As such, the UK has put in place the Advanced Skills Teacher (AST) scheme, while the US has set the ball rolling in laying down standards for the certification of the master science teacher, to distil the best teachers from this pool of highly qualified science teachers. This article examines some of the practices in the teaching-learning process one would associate with those of master science teachers. It argues for the master science teacher to have a well-developed pedagogical content knowledge rather than be an expert in content knowledge. It argues for the master science teacher to be someone who has moved 'from personal comprehension to preparing for the comprehension of others' (Shulman 1987 Harv. Educ. Rev. 75 1-22).

    2015-01-01

    Context: With the ever-increasing number of masters athletes, it is necessary to understand how to best provide medical support to this expanding population using a multidisciplinary approach. Evidence Acquisition: Relevant articles published between 2000 and 2013 using the search terms masters athlete and aging and exercise were identified using MEDLINE. Study Design: Clinical review. Level of Evidence: Level 3. Results: Preparticipation screening should assess a variety of medical comorbidities, with emphasis on cardiovascular health in high-risk patients. The masters athlete should partake in moderate aerobic exercise and also incorporate resistance and flexibility training. A basic understanding of physiology and age-related changes in muscle composition and declines in performance are prerequisites for providing appropriate care. Osteoarthritis and joint arthroplasty are not contraindications to exercise, and analgesia has an appropriate role in the setting of acute or chronic injuries. Masters athletes should follow regular training regimens to maximize their potential while minimizing their likelihood of injuries. Conclusion: Overall, masters athletes represent a unique population and should be cared for utilizing a multidisciplinary approach. This care should be implemented not only during competitions but also between events when training and injury are more likely to occur. Strength of Recommendation Taxonomy (SORT): B. PMID:26131307

  9. Evaluation of Integration Degree of the ASG-EUPOS Polish Reference Networks With Ukrainian GeoTerrace Network Stations in the Border Area

    Science.gov (United States)

    Siejka, Zbigniew

    2017-09-01

    GNSS systems are currently the basic tools for determination of the highest precision station coordinates (e.g. basic control network stations or stations used in the networks for geodynamic studies) as well as for land, maritime and air navigation. All of these tasks are carried out using active, large scale, satellite geodetic networks which are complex, intelligent teleinformatic systems offering post processing services along with corrections delivered in real-time for kinematic measurements. Many countries in the world, also in Europe, have built their own multifunctional networks and enhance them with their own GNSS augmentation systems. Nowadays however, in the era of international integration, there is a necessity to consider collective actions in order to build a unified system, covering e.g. the whole Europe or at least some of its regions. Such actions have already been undertaken in many regions of the world. In Europe such an example is the development for EUPOS which consists of active national networks built in central eastern European countries. So far experience and research show, that the critical areas for connecting these networks are border areas, in which the positioning accuracy decreases (Krzeszowski and Bosy, 2011). This study attempts to evaluate the border area compatibility of Polish ASG-EUPOS (European Position Determination System) reference stations and Ukrainian GeoTerrace system reference stations in the context of their future incorporation into the EUPOS. The two networks analyzed in work feature similar hardware parameters. In the ASG-EUPOS reference stations network, during the analyzed period, 2 stations (WLDW and CHEL) used only one system (GPS), while, in the GeoTerrace network, all the stations were equipped with both GPS and GLONASS receivers. The ASG EUPOS reference station network (95.6%) has its average completeness greater by about 6% when compared to the GeoTerrace network (89.8%).

    Redman, Mary W; Allegra, Carmen J

    2015-10-01

    During the past decade, biomedical technologies have undergone an explosive evolution-from the publication of the first complete human genome in 2003, after more than a decade of effort and at a cost of hundreds of millions of dollars-to the present time, where a complete genomic sequence can be available in less than a day and at a small fraction of the cost of the original sequence. The widespread availability of next-generation genomic sequencing has opened the door to the development of precision oncology. The need to test multiple new targeted agents both alone and in combination with other targeted therapies, as well as classic cytotoxic agents, demands the development of novel therapeutic platforms (particularly Master Protocols) capable of efficiently and effectively testing multiple targeted agents or targeted therapeutic strategies in relatively small patient subpopulations. Here, we describe the Master Protocol concept, with a focus on the expected gains and complexities of the use of this design. An overview of Master Protocols currently active or in development is provided along with a more extensive discussion of the Lung Master Protocol (Lung-MAP study). Copyright © 2015 Elsevier Inc.

  18. A robust cooperative spectrum sensing scheme based on Dempster-Shafer theory and trustworthiness degree calculation in cognitive radio networks

    Wang, Jinlong; Feng, Shuo; Wu, Qihui; Zheng, Xueqiang; Xu, Yuhua; Ding, Guoru

    2014-12-01

    Cognitive radio (CR) is a promising technology that brings about remarkable improvement in spectrum utilization. To tackle the hidden terminal problem, cooperative spectrum sensing (CSS) which benefits from the spatial diversity has been studied extensively. Since CSS is vulnerable to the attacks initiated by malicious secondary users (SUs), several secure CSS schemes based on Dempster-Shafer theory have been proposed. However, the existing works only utilize the current difference of SUs, such as the difference in SNR or similarity degree, to evaluate the trustworthiness of each SU. As the current difference is only one-sided and sometimes inaccurate, the statistical information contained in each SU's historical behavior should not be overlooked. In this article, we propose a robust CSS scheme based on Dempster-Shafer theory and trustworthiness degree calculation. It is carried out in four successive steps, which are basic probability assignment (BPA), trustworthiness degree calculation, selection and adjustment of BPA, and combination by Dempster-Shafer rule, respectively. Our proposed scheme evaluates the trustworthiness degree of SUs from both current difference aspect and historical behavior aspect and exploits Dempster-Shafer theory's potential to establish a `soft update' approach for the reputation value maintenance. It can not only differentiate malicious SUs from honest ones based on their historical behaviors but also reserve the current difference for each SU to achieve a better real-time performance. Abundant simulation results have validated that the proposed scheme outperforms the existing ones under the impact of different attack patterns and different number of malicious SUs.

  19. The Master's program in Advanced Optical Technologies: an interdisciplinary, international and individual approach

    Science.gov (United States)

    Großmann, Jürgen; Schmauss, Bernhard

    2017-08-01

    The Master's Program in Advanced Optical Technologies (MAOT) was established at the Friedrich-Alexander Universität Erlangen-Nürnberg in 2007 as part of the Elite Network of Bavaria (ENB), an initiative by the Bavarian State Government comprising about 40 elite Master's programs and doctoral programs. MAOT can be studied after a Bachelor in physics or an engineering subject. The Master's program realizes an innovative concept combining three core elements: (1) Interdisciplinarity: The program integrates courses and researchers from five engineering subjects and from physics. The degree of interdisciplinarity goes far beyond traditional programs. (2) Internationality: The program is taught entirely in English and special support is given to international students. (3). Individuality: The course curriculum was adapted at several points based on the experience in the initial years. The same is true for the way in which international students are supported and the type of support they need. The students are given an unusually high degree of freedom to develop an individual curriculum and to pursue research projects. Crucial experience and lessons learned are: (1) Lecturers and researchers have to be coordinated and the perspectives of the different disciplines have to be integrated within one program. Students must be guided in order to deal with the demands and challenges of the different disciplines. (2) International students need support with settling in Germany and with learning and working in a German cultural environment. They need support with administrative issues. Furthermore, they need to analyze and understand cultural differences and how they impact on the cooperation between lecturers and students and on the work in research groups. (3) Students must be helped to develop their own curriculum. They must learn how to combine their first-degree qualification with the specialized qualification which they gain after completing their Master's program. They

  4. A Quantitative Risk Assessment Model Involving Frequency and Threat Degree under Line-of-Business Services for Infrastructure of Emerging Sensor Networks.

    2017-03-21

    The prospect of Line-of-Business Services (LoBSs) for infrastructure of Emerging Sensor Networks (ESNs) is exciting. Access control remains a top challenge in this scenario as the service provider's server contains a lot of valuable resources. LoBSs' users are very diverse as they may come from a wide range of locations with vastly different characteristics. Cost of joining could be low and in many cases, intruders are eligible users conducting malicious actions. As a result, user access should be adjusted dynamically. Assessing LoBSs' risk dynamically based on both frequency and threat degree of malicious operations is therefore necessary. In this paper, we proposed a Quantitative Risk Assessment Model (QRAM) involving frequency and threat degree based on value at risk. To quantify the threat degree as an elementary intrusion effort, we amend the influence coefficient of risk indexes in the network security situation assessment model. To quantify threat frequency as intrusion trace effort, we make use of multiple behavior information fusion. Under the influence of intrusion trace, we adapt the historical simulation method of value at risk to dynamically access LoBSs' risk. Simulation based on existing data is used to select appropriate parameters for QRAM. Our simulation results show that the duration influence on elementary intrusion effort is reasonable when the normalized parameter is 1000. Likewise, the time window of intrusion trace and the weight between objective risk and subjective risk can be set to 10 s and 0.5, respectively. While our focus is to develop QRAM for assessing the risk of LoBSs for infrastructure of ESNs dynamically involving frequency and threat degree, we believe it is also appropriate for other scenarios in cloud computing.

    Training and education enable emergency managers to deal with complex situations, create durable networks of people with appropriate expertise, and ensure that knowledge is utilized to improve resilience in the face of disaster risk. Although there is a discrete literature on emergency management training, few attempts have been made to create an overview that discusses the key issues and proposes a standardized approach. This article examines the nature of training and education in emergency and disaster management. It analyzes the composition and requirements of courses at the master's degree level, which is considered to be the most appropriate tier for in-depth instruction in this field. This article defines "training" and "education" in the context of emergency management courses. It reviews the developing profile of the emergency manager in the light of training requirements. This article examines the question of whether emergency management is a branch of management science or whether it is something distinct and separate. Attention is given to the composition of a core curriculum and to the most appropriate pedagogical forms of delivering it. The article reviews the arguments for and against standardization of the curriculum and describes some of the pedagogical methods for delivering courses. Briefly, it considers the impact on training and education of new pedagogic methods based on information technology. It is concluded that the master's level is particularly suited to emergency and crisis management education, as it enables students to complement the in-depth knowledge they acquired in their disciplinary first degrees with a broader synthetic approach at the postgraduate level. Some measures of standardization of course offerings are desirable, in favor of creating a core curriculum that will ensure that essential core knowledge is imparted. Education and training in this field should include problem-solving approaches that enable students to learn

    The study was designed to examine the differences between leadership and management and to compare the leadership content in a sample of graduate programs in nursing with those conceptual differences. A review of seven components contained within the National League for Nursing self-study reports of 10 accredited programs in four regions of the country was conducted. Data analysis revealed that leadership, as defined in the literature, was included in most curriculum components in the graduate programs studied. The emphasis in the 10 graduate programs analyzed clearly was leadership development rather than management preparation.

    Full Text Available This study aims to analyze the characteristics of global virtual water trade (GVWT, such as the connectivity of each trader, vulnerable importers, and influential countries, using degree and eigenvector centrality during the period 2006–2010. The degree centrality was used to measure the connectivity, and eigenvector centrality was used to measure the influence on the entire GVWT network. Mexico, Egypt, China, the Republic of Korea, and Japan were classified as vulnerable importers, because they imported large quantities of virtual water with low connectivity. In particular, Egypt had a 15.3 Gm3 year−1 blue water saving effect through GVWT: the vulnerable structure could cause a water shortage problem for the importer. The entire GVWT network could be changed by a few countries, termed "influential traders". We used eigenvector centrality to identify those influential traders. In GVWT for food crops, the USA, Russian Federation, Thailand, and Canada had high eigenvector centrality with large volumes of green water trade. In the case of blue water trade, western Asia, Pakistan, and India had high eigenvector centrality. For feed crops, the green water trade in the USA, Brazil, and Argentina was the most influential. However, Argentina and Pakistan used high proportions of internal water resources for virtual water export (32.9 and 25.1 %; thus other traders should carefully consider water resource management in these exporters.

  10. A Mathematical Study of Accessibility and Cohesion Degree in a High-Speed Rail Station Connected to an Urban Bus Transport Network

    In the last twenty years, the implementation of High-Speed Rail (HSR) has been one of the major strategies for territorial structuring used by various countries. This model has enhanced the development of countries such as France, Spain, Germany and Japan. At present, the United States and China are also starting to implement this model. Nevertheless, the lack of social and economic profitability of several networks is being increasingly analysed. Many networks located in particular regions serve populations that are not large enough to recover the initial investment. For this reason, it is necessary to evaluate the population served by this transport mode, beyond the number of users. In this sense, it is essential to identify the deficiencies and potentials of implementing a network linked to other secondary networks in a specific territory which can compensate for the so-called tunnel effect. This article proposes to apply a mathematical approach based on graph theory to measure the Degree Accessibility Node (DAN) in a constrained Geographic Information System (GIS) model. Hence, it would be possible to compare regions, especially medium-sized cities, where the implementation of HSR could represent a qualitative leap due to incorporation into large transport networks. The DAN function uses static and dynamic studies to evaluate the level of connection of stations to secondary transport networks—local public transport in this case. Thus, the impact of high-speed trains could be spread to greater territorial and population ranges. Four cases have been studied, two in Germany (one of them, Fulda, is analysed in depth throughout this article) and two in Spain. These two countries were selected since HSR was implemented in the same relative period of time, in comparison with other European countries. Results show relevant differences, suggesting a review of inappropriate policies of transport integration in a city that could weaken the expansion of the positive

  16. Exciton transport in the PE545 complex: insight from atomistic QM/MM-based quantum master equations and elastic network models

    Pouyandeh, Sima; Iubini, Stefano; Jurinovich, Sandro; Omar, Yasser; Mennucci, Benedetta; Piazza, Francesco

    2017-12-01

    In this paper, we work out a parameterization of environmental noise within the Haken–Strobl–Reinenker (HSR) model for the PE545 light-harvesting complex, based on atomic-level quantum mechanics/molecular mechanics (QM/MM) simulations. We use this approach to investigate the role of various auto- and cross-correlations in the HSR noise tensor, confirming that site-energy autocorrelations (pure dephasing) terms dominate the noise-induced exciton mobility enhancement, followed by site energy-coupling cross-correlations for specific triplets of pigments. Interestingly, several cross-correlations of the latter kind, together with coupling–coupling cross-correlations, display clear low-frequency signatures in their spectral densities in the 30–70 cm-1 region. These slow components lie at the limits of validity of the HSR approach, which requires that environmental fluctuations be faster than typical exciton transfer time scales. We show that a simple coarse-grained elastic-network-model (ENM) analysis of the PE545 protein naturally spotlights collective normal modes in this frequency range that represent specific concerted motions of the subnetwork of cysteines covalenty linked to the pigments. This analysis strongly suggests that protein scaffolds in light-harvesting complexes are able to express specific collective, low-frequency normal modes providing a fold-rooted blueprint of exciton transport pathways. We speculate that ENM-based mixed quantum classical methods, such as Ehrenfest dynamics, might be promising tools to disentangle the fundamental designing principles of these dynamical processes in natural and artificial light-harvesting structures.

    Curran, James R.

    2013-01-01

    As early as the 1930s the term Master Hearing Aid (MHA) described a device used in the fitting of hearing aids. In their original form, the MHA was a desktop system that allowed for simulated or actual adjustment of hearing aid components that resulted in a changed hearing aid response. Over the years the MHA saw many embodiments and contributed to a number of rationales for the fitting of hearing aids. During these same years, the MHA was viewed by many as an inappropriate means of demonstrating hearing aids; the audio quality of the desktop systems was often superior to the hearing aids themselves. These opinions and the evolution of the MHA have molded the modern perception of hearing aids and the techniques used in the fitting of hearing aids. This article reports on a history of the MHA and its influence on the fitting of hearing aids. PMID:23686682

  1. Discrete Event-Triggered Robust Fault-Tolerant Control for Nonlinear Networked Control Systems with α-Safety Degree and Actuator Saturation

    Directory of Open Access Journals (Sweden)

    Yajie Li

    2015-01-01

    Full Text Available This paper deals with the discrete event-triggered robust fault-tolerant control problem for uncertain nonlinear networked control systems (NNCSs with α-safety degree. A discrete event-triggered communication scheme (DETCS is initially proposed, and a closed-loop fault model is subsequently established for NNCSs with actuator saturation under the DETCS. Based on an appropriately constructed delay-dependent Lyapunov–Krasovskii function, sufficient conditions are derived to guarantee the asymptotic stability of NNCSs under two different event-triggered conditions and are established as the contractively invariant sets of fault tolerance with α-safety degree. Furthermore, codesign methods between the robust fault-tolerant controller and event-triggered weight matrix are also proposed in terms of linear matrix inequality. The simulation shows that the resultant closed-loop fault NNCSs possesses a high safety margin, and an improved dynamic performance, as well as a reduced communication load. A comparative analysis of the two event-triggered conditions is discussed in the experiment section.

    Full Text Available Accuracy is paramount for the further development of parallel mechanism in real world, especially in industry. Previous research was focused on the improvement of rigidity and load capacity which is related with the stiffness matrix of closed loop kinematic structure. However, if the mechanical structure has been predefined or fabricated, stiffness matrix only can search for the optimal configuration in the workspace, but fails to enhance the accuracy at a given pose. In this research, the concept of optimal robust calibration is developed as an effective approach to largely reduce various errors of the predefined parallel mechanism. A novel coevolutionary radial basis function (RBF neural network based soft sensor is proposed to implement the optimal robust calibration procedure. A six- degrees-of-freedom parallel kinematics manipulator is selected as the case study to verify the proposed methodology. The results demonstrate that the coevolutionary neural network possesses the excellent performance as a smart soft sensor for the calibration of closed loop kinematic structure.

    2013-01-01

    The Master Console oversees the function of Computer Systems in Firing room 1 (FR1). Master Console Operators, MCOs' for short, are our customer. I was integrated into the System Monitoring and Control (SMC) software team that is under the guidance of David Slaiman, who is the product group lead. I have been brought up to speed with System Monitoring and Control. The initial time spent reading SMC software design description and understanding how it works. The current Firing Room 1 Console Display is a floor layout giving the MCO two essential pieces of information which are Health and Status. When an issue arises, the MCO has to look on the display to find which console is affected and then the MCO must use the Reference designator from the display to manually search for the Portal Workstation (PWS) installed in the console using the hardware map; which is a long process to lookup a PWS if an issue is present. My project is to make the FR1 Console Display easier for the MCO's to pinpoint PWS's without having to lookup additional resources in the process. My project also includes updating Firing Room 1 Console Display to include the F1R Non-Redundant Set. The display does not have good use of space and functionality. PWS numbers were not present in the previous design and are the critical component in efficient understanding and administration of the consoles. Part of the process includes getting feedback from the customer, instead of just emailing them with a question, we made a proposal with changes so they could respond and give us their input; which proved to be an effective method for engaging them. In order to do this I had to use the Display Editor (DE) tool developed by NASA, Paint.Net and Visio. The process I have been using has been Visio to alter the floor layout of Firing Room and take advantage of the white areas, and then I take the altered floor plan into Paint.Net. Once in Paint.Net I put the new floor plan as a background to the standard console

    A master-equation approach to the stochastic neurodynamics proposed by Cowan [in Advances in Neural Information Processing Systems 3, edited by R. P. Lippman, J. E. Moody, and D. S. Touretzky (Morgan Kaufmann, San Mateo, 1991), p. 62] is investigated in this paper. We deal with a model neural network that is composed of two-state neurons obeying elementary stochastic transition rates. We show that such an approach yields concise expressions for multipoint moments and an equation of motion. We apply the formalism to a (1+1)-dimensional system. Exact and approximate expressions for various statistical parameters are obtained and compared with Monte Carlo simulations.

    Sex determination offers an opportunity to address many classic questions of developmental biology. In addition, because sex determination evolves rapidly, it offers an opportunity to investigate the evolution of genetic hierarchies. Sex determination in Drosophila melanogaster is controlled by the master regulatory gene, Sex lethal (Sxl). DmSxl controls the alternative splicing of a downstream gene, transformer (tra), which acts with tra2 to control alternative splicing of doublesex (dsx). DmSxl also controls its own splicing, creating an autoregulatory feedback loop that ensures expression of Sxl in females, but not males. A recent paper has shown that in the dipteran Ceratitis capitata later (downstream) steps in the regulatory hierarchy are conserved, while earlier (upstream) steps are not. Cctra is regulated by alternative splicing and apparently controls the alternative splicing of Ccdsx. However, Cctra is not regulated by CcSxl. Instead it appears to autoregulate in a manner similar to the autoregulation seen with DmSxl. Copyright 2002 Wiley Periodicals, Inc.

Synthetic biology is the promising discipline that focuses on the construction of these new biological systems. Synthetic biology is an engineering discipline, and as such, it can benefit from mathematical modeling. This chapter focuses on mathematical models of biological systems. These models take the form of chemical reaction networks. The importance of stochasticity is discussed and methods to simulate stochastic reaction networks are reviewed. A closure scheme solution is also presented for the master equation of chemical reaction networks. The master equation is a complete model of randomly evolving molecular populations. Because of its ambitious character, the master equation remained unsolved for all but the simplest of molecular interaction networks for over 70 years. With the first complete solution of chemical master equations, a wide range of experimental observations of biomolecular interactions may be mathematically conceptualized. We anticipate that models based on the closure scheme described herein may assist in rationally designing synthetic biological systems.

    The review examples of usage of the Latin term magister (master) in various common titles throughout the past, particularly in Croatia. As early as the Roman Empire and until the Middle Ages, the title magister designated various functions and duties, generally denoting authority, higher rank, or a responsible position. The review highlights certain historical events and persons related to the usage of the title magister. Ever since the Middle Ages, the title has specifically denoted various health care professions. The term was used in Latin, as it was the official language in Croatia at the time, for example, m. chirurgiae (master of surgery), m. obstetritiae (master of obstetrics), m. artis occularis (master of the eye-related skills), m. hospitalis (master of the hospice), m. sanitatis (health care master). As an example, the review shows the difference between the titles doctor medicinae and m. obstetritiae according to John the Baptist Lalangue (1743-1799), the official physician of the Varazdin county in the Hapsburg Empire and one of the most prominent figures in the history of health care in Croatia. Lalangue was the author of the first professional medical book in the Croatian language published in 1776 and of several other books in Croatian. The books were meant to teach medical professionals and ordinary people how to improve their health. Beside the title of medical doctor, Lalangue held the title of m. obstetritiae which he earned through additional education. He thought it was essential for a complete health provider to be trained both in general practice and in obstetrics which, at the time, included infant care. Nowadays in Croatia, only persons who are graduate pharmacists use magister pharmaciae as a professional title. The title is otherwise strictly reserved to denote an academic degree between the bachelor's and the doctoral in a particular field. The title magister scientiarum (Master of Science) is achieved upon completion of a postgraduate

    Comprehensive reading, writing, research, and study skills play a critical role in a graduate student's success and ability to contribute to a field of study effectively. The literature indicated a need to support graduate student success in the areas of mentoring, navigation, as well as research and writing. The purpose of this two-phased mixed methods explanatory study was to examine factors that characterize student success at the Master's level in the fields of education, sociology and social work. The study was grounded in a transformational learning framework which focused on three levels of learning: technical knowledge, practical or communicative knowledge, and emancipatory knowledge. The study included two data collection points. Phase one consisted of a Master's Level Success questionnaire that was sent via Qualtrics to graduate level students at three colleges and universities in the Central Valley of California: a California State University campus, a University of California campus, and a private college campus. The results of the chi-square indicated that seven questionnaire items were significant with p values less than .05. Phase two in the data collection included semi-structured interview questions that resulted in three themes emerged using Dedoose software: (1) the need for more language and writing support at the Master's level, (2) the need for mentoring, especially for second-language learners, and (3) utilizing the strong influence of faculty in student success. It is recommended that institutions continually assess and strengthen their programs to meet the full range of learners and to support students to degree completion.

    Prices charged for imaging services can be found in the charge master, a catalog of retail list prices for medical goods and services. This article reviews the evolution of reimbursement in the United States and provides a balanced discussion of the factors that influence charge master prices. Reduced payments to hospitals have pressured hospitals to generate additional revenue by increasing charge master prices. An unfortunate consequence is that those least able to pay for health care, the uninsured, are subjected to the highest charges. Yet, differences in pricing also represent an opportunity for radiology practices, which provide imaging services that are larger in scope or superior in quality to promote product differentiation. Physicians, hospital executives, and policy makers need to work together to improve the existing reimbursement system to promote high-quality, low-cost imaging. Copyright © 2016 Mosby, Inc.

    The share of distributed renewable generation is dramatically growing since years in Germany due to the existing subsidies for renewable energy sources. As a consequence the existing distribution networks and primarily the low-voltage (LV) networks have to change to maintain the same degree of power quality and security of supply. This paper described resulting new challenges, which will have a major impact on the distribution networks. To solve the problems today utilities are mainly focussing on conventional measures, like network extension or adding new substation. Compared to this classical measures new solutions and technologies are described. These solutions shall enable the distribution network operators (DSO) to optimize the necessary investment costs. Finally the main described solutions will be evaluated and compared to the conventional measures using three typical and realistic LV networks. For each network the share of renewable energy is adjusted in different steps and the impact on the network is assessed taking into account the technical as well as the economic behaviour. (orig.)

  19. Lumping of degree-based mean-field and pair-approximation equations for multistate contact processes

    2018-01-01

    Contact processes form a large and highly interesting class of dynamic processes on networks, including epidemic and information-spreading networks. While devising stochastic models of such processes is relatively easy, analyzing them is very challenging from a computational point of view, particularly for large networks appearing in real applications. One strategy to reduce the complexity of their analysis is to rely on approximations, often in terms of a set of differential equations capturing the evolution of a random node, distinguishing nodes with different topological contexts (i.e., different degrees of different neighborhoods), such as degree-based mean-field (DBMF), approximate-master-equation (AME), or pair-approximation (PA) approaches. The number of differential equations so obtained is typically proportional to the maximum degree kmax of the network, which is much smaller than the size of the master equation of the underlying stochastic model, yet numerically solving these equations can still be problematic for large kmax. In this paper, we consider AME and PA, extended to cope with multiple local states, and we provide an aggregation procedure that clusters together nodes having similar degrees, treating those in the same cluster as indistinguishable, thus reducing the number of equations while preserving an accurate description of global observables of interest. We also provide an automatic way to build such equations and to identify a small number of degree clusters that give accurate results. The method is tested on several case studies, where it shows a high level of compression and a reduction of computational time of several orders of magnitude for large networks, with minimal loss in accuracy.

  20. Concept for a large master/slave-controlled robotic hand

    Science.gov (United States)

    1988-01-01

    A strategy is presented for the design and construction of a large master/slave-controlled, five-finger robotic hand. Each of the five fingers will possess four independent axes each driven by a brushless DC servomotor and, thus, four degrees-of-freedom. It is proposed that commercially available components be utilized as much as possible to fabricate a working laboratory model of the device with an anticipated overall length of two-to-four feet (0.6 to 1.2 m). The fingers are to be designed so that proximity, tactile, or force/torque sensors can be imbedded in their structure. In order to provide for the simultaneous control of the twenty independent hand joints, a multilevel master/slave control strategy is proposed in which the operator wears a specially instrumented glove which produces control signals corresponding to the finger configurations and which is capable of conveying sensor feedback signals to the operator. Two dexterous hand master devices are currently commercially available for this application with both undergoing continuing development. A third approach to be investigated for the master control mode is the use of real-time image processing of a specially patterned master glove to provide the respective control signals for positioning the multiple finger joints.

    The use of remotely operated robots and other mechanical devices as replacements of human workers in hazardous environments is a growing field of research. In particular, master-slave manipulators have been extensively used in the nuclear industries governed by the ALARA principle for more than four decades. There, however, are still few successful implementations of complex and high degree-of-freedom systems. The master manipulator is an input device which interfaces with the human operator on one side and with the slave manipulator on the other. Bilateral force-reflecting control plays a key supporting role in successful dexterous manipulation of the master-slave manipulators. Great increase in performance of the master-slave manipulator system can be achieved through good design of mechanical hardware and proper implementation of the embedded control strategies. This report presents some of design issues relevant to designers of the master manipulator as man-machine interface device in the master-slave manipulator system. Significant design parameters for both the replica and universal master manipulators are evaluated. In addition, the report describes the various control schemes of the bilateral force-reflecting master-slave manipulators, discusses the analysis and synthesis of the control loop between the master and slave manipulators, and examines the necessary position and force information on both sides.

    %. The collected data was analyzed by using regression and reliability analysis. The purpose of the questionnaire was to find out the extent to which students generally initiated cooperation with colleagues and whether there is a link between the extent of their initiative and their experience of the cooperation. The data obtained by the questionnaire is based on the students' own reflections and experiences of the cooperative processes with their colleagues and employers.The results show a statistical correlation between the students' own initiative and experience of cooperation with colleagues or employers, that is to say that a colleague or manager has participated in the research work: for example with data collection, by making his or her teaching available in the research or by having participated in the analysis of the results, reflection and discussions.  The tests show that this only occurs to a very limited extent.  There are other factors that are involved and these are not considered as variables in the study.Although the students have taken initiative to cooperate with leaders and colleagues in their workplace they experience only a limited degree of cooperation with them. Furthermore, the results show that the knowledge gained by the individual students is seldom shared with their colleagues at work / community of practice.   Conclusion: The study concludes that there is a correlation between students' initiated cooperation and students' experience of cooperation with colleagues and employers. Still, it cannot be taken for granted that colleagues and employers will be interested even if students take the initiative to cooperate. The findings highlight continued research on other relevant forms of cooperation, where Master degree students in Vocational pedagogy find partners outside and not within their own work place.

    Full Text Available The Maribor Town plan project began in 1995. The elaborate analytical part was directed into recognising and establishing key problems in the town and guidelines for their solution. Expert guidelines were elaborated and presented as conceptual ideas, easily understood by professionals and lay-people. The concept of the master plan or town plan as such is based on the division and connection of the four parts of the town. In the concluding remarks certain ideas on improving the planning system are presented.

  15. Quantum adiabatic Markovian master equations

    Albash, Tameem; Boixo, Sergio; Lidar, Daniel A.; Zanardi, Paolo

    2012-12-01

    We develop from first principles Markovian master equations suited for studying the time evolution of a system evolving adiabatically while coupled weakly to a thermal bath. We derive two sets of equations in the adiabatic limit, one using the rotating wave (secular) approximation that results in a master equation in Lindblad form, the other without the rotating wave approximation but not in Lindblad form. The two equations make markedly different predictions depending on whether or not the Lamb shift is included. Our analysis keeps track of the various time and energy scales associated with the various approximations we make, and thus allows for a systematic inclusion of higher order corrections, in particular beyond the adiabatic limit. We use our formalism to study the evolution of an Ising spin chain in a transverse field and coupled to a thermal bosonic bath, for which we identify four distinct evolution phases. While we do not expect this to be a generic feature, in one of these phases dissipation acts to increase the fidelity of the system state relative to the adiabatic ground state.

    Synchronization is one of the most important features observed in large-scale complex networks of interacting dynamical systems. As is well known, there is a close relation between the network topology and the network synchronizability. Using the coupled Hindmarsh–Rose neurons with community structure as a model network, in this paper we explore how failures of the nodes due to random errors or intentional attacks affect the synchronizability of community networks. The intentional attacks are realized by removing a fraction of the nodes with high values in some centrality measure such as the centralities of degree, eigenvector, betweenness and closeness. According to the master stability function method, we employ the algebraic connectivity of the considered community network as an indicator to examine the network synchronizability. Numerical evidences show that the node failure strategy based on the betweenness centrality has the most influence on the synchronizability of community networks. With this node failure strategy for a given network with a fixed number of communities, we find that the larger the degree of communities, the worse the network synchronizability; however, for a given network with a fixed degree of communities, we observe that the more the number of communities, the better the network synchronizability.

    Biologically detailed single neuron and network models are important for understanding how ion channels, synapses and anatomical connectivity underlie the complex electrical behavior of the brain. While neuronal simulators such as NEURON, GENESIS, MOOSE, NEST, and PSICS facilitate the development of these data-driven neuronal models, the specialized languages they employ are generally not interoperable, limiting model accessibility and preventing reuse of model components and cross-simulator validation. To overcome these problems we have used an Open Source software approach to develop NeuroML, a neuronal model description language based on XML (Extensible Markup Language). This enables these detailed models and their components to be defined in a standalone form, allowing them to be used across multiple simulators and archived in a standardized format. Here we describe the structure of NeuroML and demonstrate its scope by converting into NeuroML models of a number of different voltage- and ligand-gated conductances, models of electrical coupling, synaptic transmission and short-term plasticity, together with morphologically detailed models of individual neurons. We have also used these NeuroML-based components to develop an highly detailed cortical network model. NeuroML-based model descriptions were validated by demonstrating similar model behavior across five independently developed simulators. Although our results confirm that simulations run on different simulators converge, they reveal limits to model interoperability, by showing that for some models convergence only occurs at high levels of spatial and temporal discretisation, when the computational overhead is high. Our development of NeuroML as a common description language for biophysically detailed neuronal and network models enables interoperability across multiple simulation environments, thereby improving model transparency, accessibility and reuse in computational neuroscience.

    The structure and dynamic of social network are largely determined by the heterogeneous interaction activity and social capital allocation of individuals. These features interplay in a non-trivial way in the formation of network and challenge a rigorous dynamical system theory of network evolution. Here we study seven real networks describing temporal human interactions in three different settings: scientific collaborations, Twitter mentions, and mobile phone calls. We find that the node's activity and social capital allocation can be described by two general functional forms that can be used to define a simple stochastic model for social network dynamic. This model allows the explicit asymptotic solution of the Master Equation describing the system dynamic, and provides the scaling laws characterizing the time evolution of the social network degree distribution and individual node's ego network. The analytical predictions reproduce with accuracy the empirical observations validating the theoretical approach....

    There is an increasing trend in using robots for medical purposes. One specific area is rehabilitation. Rehabilitation is one of the non-drug treatments in community health which means the restoration of the abilities to maximize independence. It is a prolonged work and costly labor. On the other hand, by using the flexible and efficient robots in rehabilitation area, this process will be more useful for handicapped patients. In this study, a rule-based intelligent control methodology is proposed to mimic the behavior of a healthy limb in a satisfactory way by a 2-DOF planar robot. Inverse kinematic of the planar robot will be solved by neural networks and control parameters will be optimized by genetic algorithm, as rehabilitation progress. The results of simulations are presented by defining a physiotherapy simple mode on desired trajectory. MATLAB/Simulink is used for simulations. The system is capable of learning the action of the physiotherapist for each patient and imitating this behaviour in the absence of a physiotherapist that can be called robotherapy. In this study, a therapeutic exercise planar 2-DOF robot is designed and controlled for lower-limb rehabilitation. The robot manipulator is controlled by combination of hybrid and adaptive controls. Some safety factors and stability constraints are defined and obtained. The robot is stopped when the safety factors are not satisfied. Kinematics of robot is estimated by an MLP neural network and proper control parameters are achieved using GA optimization.

    2015-04-01

    Current major objectives of Master's degrees taught at the University of Salamanca are to incorporate multidisciplinary skills and to address international issues. It is important to ensure that students and early career scientists have all of the necessary skills to deal with professional development before career planning whether in academic research, professional practices or alternative careers, whether in Spain or elsewhere. However, many students choose a Master's programme without sufficient understanding of what they might need to deal with. A multidisciplinary degree course at the University of Salamanca, linked to the Institute of Social Studies for Science and Technology, focuses on training potential experts equipped to mediate between participants in science and technology and the wider public. Students participating in this course currently come from Spanish speaking countries. Because the course is taught mainly in Spanish, subsequent outreach might also be confined to Spanish speaking communities. Even so, it is essential to properly explain, at the outset, the aims of the Master's programme and the international potential of the qualification to attract more. Here we propose the use of MOOCs (Massive Open Online Courses) both to help students to know about the content and other details of the Master program before they join in and to internationalize the course to reach more potential interested students in the subject. This will be the first experience implementing MOOCs in the teaching of masters at the University of Salamanca and, if successful, the experience can be applied to other masters and courses in need of students and internationalization.

  13. Interplay of degree correlations and cluster synchronization

    Science.gov (United States)

    2016-12-01

    We study the evolution of coupled chaotic dynamics on networks and investigate the role of degree-degree correlation in the networks' cluster synchronizability. We find that an increase in the disassortativity can lead to an increase or a decrease in the cluster synchronizability depending on the degree distribution and average connectivity of the network. Networks with heterogeneous degree distribution exhibit significant changes in cluster synchronizability as well as in the phenomena behind cluster synchronization as compared to those of homogeneous networks. Interestingly, cluster synchronizability of a network may be very different from global synchronizability due to the presence of the driven phenomenon behind the cluster formation. Furthermore, we show how degeneracy at the zero eigenvalues provides an understanding of the occurrence of the driven phenomenon behind the synchronization in disassortative networks. The results demonstrate the importance of degree-degree correlations in determining cluster synchronization behavior of complex networks and hence have potential applications in understanding and predicting dynamical behavior of complex systems ranging from brain to social systems.

    This paper presents a 7 degrees-of-freedom (7-DOF) haptic master which is applicable to the robot-assisted minimally invasive surgery (RMIS). By utilizing a controllable magneto-rheological (MR) fluid, the haptic master can provide force information to the surgeon during surgery. The proposed haptic master consists of three degrees motions of X, Y, Z and four degrees motions of the pitch, yaw, roll and grasping. All of them have force feedback capability. The proposed haptic master can generate the repulsive forces or torques by activating MR clutch and MR brake. Both MR clutch and MR brake are designed and manufactured with consideration of the size and output torque which is usable to the robotic surgery. A proportional-integral-derivative (PID) controller is then designed and implemented to achieve torque/force tracking trajectories. It is verified that the proposed haptic master can track well the desired torque and force occurred in the surgical place by controlling the input current applied to MR clutch and brake.

    Over the last 50 years leading international organisations have been emphasising the key role that midwives play in the provision of quality care for women and babies throughout the pregnancy continuum. Midwifery education, however, generally remained at pre-university level until recently when Bachelors' programmes were developed. In Europe this development was taken further with the awarding of a European Union Lifelong Learning Programme grant to a consortium of five universities in four countries to develop a joint Master's degree in midwifery. The first students, drawn not only from the countries of the partner institutions but also from other European countries and from countries outside of Europe, commenced their studies in 2009. DOES THE PROGRAMME MEET ITS OBJECTIVES AND THOSE SET OUT IN THE LANCET SERIES?: The objectives of the programme were in line with the requirements for effective midwifery care and evidence based practice as discussed in the Lancet series. As an EU funded project all the goals were met. However, in terms of its long-term sustainability problems arose due to the need for universities to rationalise programmes. The number of students has remained steady but low with the projected growth not taking place thus it has been impossible to perceive an impact on midwifery practice and the health of women and children where graduates are working. Despite limitations, the programme serves as an exemplary model of how a Master's programme in midwifery can be successfully built through a collaboration of interested parties from different countries, and can be applied at a global level in other regions of the world, with sufficient political and economic support.

    A thorough understanding of the requirements for successful master-slave robotic systems is becoming increasingly desirable. Such systems can aid in the accomplishment of tasks that are hazardous or inaccessible to humans. Although a history of use has proven master-slave systems to be viable, system requirements and the impact of specifications on the human factors side of system performance are not well known. In support of the next phase of teleoperation research being conducted at the Armstrong Research Laboratory, a force-reflecting, seven degree of freedom exoskeleton for master-slave teleoperation has been concepted, and is presently being developed. The exoskeleton has a unique kinematic structure that complements the structure of the human arm. It provides a natural means for teleoperating a dexterous, possibly redundant manipulator. It allows ease of use without operator fatigue and faithfully follows human arm and wrist motions. Reflected forces and moments are remotely transmitted to the operator hand grip using a cable transmission scheme. This paper presents the exoskeleton concept and development results to date. Conceptual design, hardware, algorithms, computer architecture, and software are covered.

Although this demonstrably leads to better performance on several networks, it is not obvious whether modeling node degree is always appropriate or necessary. We formulate the degree...... corrected stochastic block model as a nonparametric Bayesian model, incorporating a parameter to control the amount of degree correction that can then be inferred from data.

    An extensive proteostatic network comprised of molecular chaperones and protein clearance mechanisms functions collectively to preserve the integrity and resiliency of the proteome. The efficacy of this network deteriorates during aging, coinciding with many clinical manifestations, including protein aggregation diseases of the nervous system. A decline in proteostasis can be delayed through the activation of cytoprotective transcriptional responses, which are sensitive to environmental stress and internal metabolic and physiological cues. The homeodomain-interacting protein kinase (hipk) family members are conserved transcriptional co-factors that have been implicated in both genotoxic and metabolic stress responses from yeast to mammals. We demonstrate that constitutive expression of the sole Caenorhabditis elegans Hipk homolog, hpk-1, is sufficient to delay aging, preserve proteostasis, and promote stress resistance, while loss of hpk-1 is deleterious to these phenotypes. We show that HPK-1 preserves proteostasis and extends longevity through distinct but complementary genetic pathways defined by the heat shock transcription factor (HSF-1), and the target of rapamycin complex 1 (TORC1). We demonstrate that HPK-1 antagonizes sumoylation of HSF-1, a post-translational modification associated with reduced transcriptional activity in mammals. We show that inhibition of sumoylation by RNAi enhances HSF-1-dependent transcriptional induction of chaperones in response to heat shock. We find that hpk-1 is required for HSF-1 to induce molecular chaperones after thermal stress and enhances hormetic extension of longevity.

    2006-11-01

    More than twenty distance learning courses in physics have been taken by hundreds of High School Physics Teachers over the past 7 years. The success of these courses helped initiate our 30 credit Master of Arts in Physics Education degree program. We have graduated 28 teachers over the last 6 years and expect 13 more to graduate in 2006. The candidates earn 14 credits in residence at the University of Virginia and 16 credits online. This allows teachers to matriculate, while earning more than half the credits at home. Presently, there are over 50 Master degree candidates. Three of the five online courses utilize CD-ROMS with edited lectures of live Physics courses taught at the University of Virginia by Physics Professors recognized for their teaching. Homework and examinations are submitted using WebAssign. Local high school teachers and administrators proctor the examinations. General communication and pedagogical feedback on homework assignments and exams are submitted through Blackboard as well as email. Screen captured video shots of physics demonstrations are widely used in the audio chat room to facilitate discussion and also used on examinations. We will discuss the changes of our distance-learning model based on what has worked (or not) and new technology.

    In the past 15 years, the Department of Physics at the University of Virginia in collaboration with the Curry School of Education has supported numerous summer high school physics and physical science teacher enrichment programs through the School of Continuing and Professional Studies. As a result of this accumulated experience in working with teachers, we created the Master of Arts in Physics Education (MAPE) program to address the needs of the high school physics teacher of the present and future. Through distance learning and summer study at UVa, participants earn the 30 hours needed for the Masters degree within 2 1/2 years while maintaining their current teaching position. Summer study includes the calculus based primary physics courses 631, 632, and 633 and associated laboratory courses. Summer physics course assignments and responsibilities do not terminate until late in the fall. Distance learning during the academic year is accomplished via the Internet using WebAssign, chat rooms, email, videotapes, and streamline video. Although recently approved in the spring 2000, 12 teachers have already graduated with the MAPE degree.

    2012-12-01

    Current endurance champions are turning in winning performances in their late 30s and 40s. These masters-age athletes present a special challenge to Sport Medicine practitioners who in previous decades have simply advised masters-aged athletes to stop competing to prevent or treat injury. The fact is, many of the physical changes commonly attributed to aging alone are actually due to the rages of sedentary aging. Recently a body of literature emerged which begins to define what we are capable of with chronic high-level exercise and guides masters-age athletes to train and rehab smarter to stay competitive. The factors influencing the relative declines in overall performance in the various sports include both physiological and lifestyle changes. The following review summarizes age and sex-related changes in triathlon performance, the biology of aging as it relates to endurance sport and factors that affect performance in the masters athletes.

    Single photon emission tomographic imaging of myocardial perfusion with 99Tcm-labelled agents is usually performed with single-detector gamma camera systems and 180 degrees anterior data collection. With multi-detector systems, reconstruction over 180 degrees and 360 degrees has been reported. We used a data set of normal subjects to compare both reconstruction methods. In addition, we tested an alternative approach, reconstructing data from 240 degrees acquisitions, excluding the right posterior views, which provide little myocardial information and which are responsible for a reduced signal-to-noise ratio. On the transverse slices, the known apical distortion with the 180 degrees reconstruction was not noted with the 360 degrees or 240 degrees reconstructions. Using semi-quantitative analysis of apical, mid-ventricular and basal short-axis slices, almost complete overlap was observed between the 240 degrees and 360 degrees circumferential profiles of our 20 normal volunteers, except in the inferior wall where a reduction in activity was noted. However, this finding was less pronounced with the 240 degrees than with the 180 degrees reconstruction. The frequent reduction in activity in the anterior wall was more prominent with the 180 degrees than with the 240 degrees and 360 degrees reconstructions. A 240 degrees acquisition represents a useful compromise between 180 degrees and 360 degrees imaging protocols when a single-detector device is used, allowing more homogeneous tracer distribution and a reduction in the apical distortion without material change of contrast or doubling of the acquisition time.

  18. Synchronization properties of heterogeneous neuronal networks with mixed excitability type.

    We study the synchronization of neuronal networks with dynamical heterogeneity, showing that network structures with the same propensity for synchronization (as quantified by master stability function analysis) may develop dramatically different synchronization properties when heterogeneity is introduced with respect to neuronal excitability type. Specifically, we investigate networks composed of neurons with different types of phase response curves (PRCs), which characterize how oscillating neurons respond to excitatory perturbations. Neurons exhibiting type 1 PRC respond exclusively with phase advances, while neurons exhibiting type 2 PRC respond with either phase delays or phase advances, depending on when the perturbation occurs. We find that Watts-Strogatz small world networks transition to synchronization gradually as the proportion of type 2 neurons increases, whereas scale-free networks may transition gradually or rapidly, depending upon local correlations between node degree and excitability type. Random placement of type 2 neurons results in gradual transition to synchronization, whereas placement of type 2 neurons as hubs leads to a much more rapid transition, showing that type 2 hub cells easily "hijack" neuronal networks to synchronization. These results underscore the fact that the degree of synchronization observed in neuronal networks is determined by a complex interplay between network structure and the dynamical properties of individual neurons, indicating that efforts to recover structural connectivity from dynamical correlations must in general take both factors into account.

  20. NFIX as a Master Regulator for Lung Cancer Progression

    Directory of Open Access Journals (Sweden)

    Nor I. A. Rahman

    2017-08-01

    Full Text Available About 40% of lung cancer cases globally are diagnosed at the advanced stage. Lung cancer has a high mortality and overall survival in stage I disease is only 70%. This study was aimed at finding a candidate of transcription regulator that initiates the mechanism for metastasis by integrating computational and functional studies. The genes involved in lung cancer were retrieved using in silico software. 10 kb promoter sequences upstream were scanned for the master regulator. Transient transfection of shRNA NFIXs were conducted against A549 and NCI-H1299 cell lines. qRT-PCR and functional assays for cell proliferation, migration and invasion were carried out to validate the involvement of NFIX in metastasis. Genome-wide gene expression microarray using a HumanHT-12v4.0 Expression BeadChip Kit was performed to identify differentially expressed genes and construct a new regulatory network. The in silico analysis identified NFIX as a master regulator and is strongly associated with 17 genes involved in the migration and invasion pathways including IL6ST, TIMP1 and ITGB1. Silencing of NFIX showed reduced expression of IL6ST, TIMP1 and ITGB1 as well as the cellular proliferation, migration and invasion processes. The data was integrated with the in silico analyses to find the differentially expressed genes. Microarray analysis showed that 18 genes were expressed differentially in both cell lines after statistical analyses integration between t-test, LIMMA and ANOVA with Benjamini-Hochberg adjustment at p-value < 0.05. A transcriptional regulatory network was created using all 18 genes, the existing regulated genes including the new genes PTCH1, NFAT5 and GGCX that were found highly associated with NFIX, the master regulator of metastasis. This study suggests that NFIX is a promising target for therapeutic intervention that is expected to inhibit metastatic recurrence and improve survival rate.

  1. Precise control of a four degree-of-freedom permanent magnet biased active magnetic bearing system in a magnetically suspended direct-driven spindle using neural network inverse scheme

    The capacity of improving the control accuracy and dynamic performance of a four degree-of-freedom (DOF) permanent magnet biased active magnetic bearing (PMBAMB) system is critical to developing and maintaining a high precision application in a magnetically suspended direct-driven spindle system. The 4-DOF PMBAMB system, however, is a multivariable, strong coupled and nonlinear system with unavoidable and unmeasured external disturbances, in addition to having parameter variations. The satisfactory control performance cannot be obtained by using traditional strategies. Therefore, it is important to present a novel control scheme to construct a robust controller with good closed-loop capability. This paper proposes a new decoupling control scheme for a 4-DOF PMBAMB in a direct-driven spindle system based on the neural network inverse (NNI) and 2- degree-of-freedom (DOF) internal model control method. By combining the inversion of the 4-DOF PMBAMB system with its original system, a new pseudolinear system can be developed. In addition, by introducing the 2-DOF internal model controller into the pseudolinear system to design extra closed-loop controllers, we can effectively eliminate the influence of the unmodeled dynamics to the decoupling control accuracy, as well as adjust the properties of tracking and disturbance rejection independently. The experimental results demonstrate the effectiveness of the proposed control scheme.

    2010-01-01

    Full Text Available The master of the ship is the person on the board who has the qualification and the necessary certificate of competency for running a maritime transport ship. He is the one who takes the ship into administration from the ship-owner, he is the only leader, the legal and direct chief of the entire crew, being invested with authority upon all the members of the crew. The master fulfils the attributes and displays his activity according to the legal laws of his flag, of the marine regulations and of the international conventions. In all the relationships which he establishes with physical or juridical people, the master represents the ship-owner, in a double condition, as an officer and as a commercial manager. In this paper, it is analysed the situation of the ship masters, the relationships which these masters have with the crew and the problems which appear during their voyage. At the end of the paper there are proposed measures to increase the quality of the training of the ship masters, to solve the situations connected with the members of the crew.

    2008-01-01

    The implementation of new medical licensing regulations (AAppO 2003) was the starting point for radical curricular changes in all German medical schools. In 2004, the postgraduate and interfaculty Master of Medical Education (MME) degree programme was established at the University of Heidelberg under the auspices of the Medical Faculty Association (Medizinischer Fakultätentag, MFT) and supported by the Association for the Promotion of Science and Humanities in Germany (Stifterverband für die Deutsche Wissenschaft). This new degree programme is intended to train multipliers and leaders in medical education, to build a German-speaking network and to strengthen educational research. The eight one-week MME modules are organised by seven locations in Germany (Munich, Tuebingen, Muenster/Essen, Berlin, Heidelberg, Cologne, Dresden) and an annually changing international faculty. The instructor teams are composed of national and international experts. Major focal points include: curriculum development, education theory, teaching and exam methods, evaluations, team building and group dynamics, project management, leadership, and faculty development, as well as educational research. The modules are connected with each other longitudinally: each participant conducts a project to improve teaching in his or her own faculty and writes a master's thesis about an educational research project. Overall, the participants earn 60 ECTS (European Credit Transfer System) in the course of two years while working. So far 100 participants (25 per year) from 33 of 34 medical faculties have started the program and 19 participants (50% of the participants from Cohort 1, 29% of the participants from Cohort 2) completed the program. The evaluation of the individual modules showed a very high level of participant satisfaction. In two modules, the evaluation results demonstrated a need for change. In 2006, an external evaluation conducted by international experts positively highlighted the MME

  11. Distribution of shortest path lengths in a class of node duplication network models

    Science.gov (United States)

    Steinbock, Chanania; Biham, Ofer; Katzav, Eytan

    2017-09-01

    We present analytical results for the distribution of shortest path lengths (DSPL) in a network growth model which evolves by node duplication (ND). The model captures essential properties of the structure and growth dynamics of social networks, acquaintance networks, and scientific citation networks, where duplication mechanisms play a major role. Starting from an initial seed network, at each time step a random node, referred to as a mother node, is selected for duplication. Its daughter node is added to the network, forming a link to the mother node, and with probability p to each one of its neighbors. The degree distribution of the resulting network turns out to follow a power-law distribution, thus the ND network is a scale-free network. To calculate the DSPL we derive a master equation for the time evolution of the probability Pt(L =ℓ ) , ℓ =1 ,2 ,⋯ , where L is the distance between a pair of nodes and t is the time. Finding an exact analytical solution of the master equation, we obtain a closed form expression for Pt(L =ℓ ) . The mean distance 〈L〉 t and the diameter Δt are found to scale like lnt , namely, the ND network is a small-world network. The variance of the DSPL is also found to scale like lnt . Interestingly, the mean distance and the diameter exhibit properties of a small-world network, rather than the ultrasmall-world network behavior observed in other scale-free networks, in which 〈L〉 t˜lnlnt .

  12. ACCURATE CHEMICAL MASTER EQUATION SOLUTION USING MULTI-FINITE BUFFERS

    Cao, Youfang; Terebus, Anna; Liang, Jie

    2016-01-01

    The discrete chemical master equation (dCME) provides a fundamental framework for studying stochasticity in mesoscopic networks. Because of the multi-scale nature of many networks where reaction rates have large disparity, directly solving dCMEs is intractable due to the exploding size of the state space. It is important to truncate the state space effectively with quantified errors, so accurate solutions can be computed. It is also important to know if all major probabilistic peaks have been computed. Here we introduce the Accurate CME (ACME) algorithm for obtaining direct solutions to dCMEs. With multi-finite buffers for reducing the state space by O(n!), exact steady-state and time-evolving network probability landscapes can be computed. We further describe a theoretical framework of aggregating microstates into a smaller number of macrostates by decomposing a network into independent aggregated birth and death processes, and give an a priori method for rapidly determining steady-state truncation errors. The maximal sizes of the finite buffers for a given error tolerance can also be pre-computed without costly trial solutions of dCMEs. We show exactly computed probability landscapes of three multi-scale networks, namely, a 6-node toggle switch, 11-node phage-lambda epigenetic circuit, and 16-node MAPK cascade network, the latter two with no known solutions. We also show how probabilities of rare events can be computed from first-passage times, another class of unsolved problems challenging for simulation-based techniques due to large separations in time scales. Overall, the ACME method enables accurate and efficient solutions of the dCME for a large class of networks. PMID:27761104

    We derive Markovian master equations for single and interacting harmonic systems in different scenarios, including strong internal coupling. By comparing the dynamics resulting from the corresponding master equations with numerical simulations of the global system's evolution, we delimit their validity regimes and assess the robustness of the assumptions usually made in the process of deriving the reduced Markovian dynamics. The results of these illustrative examples serve to clarify the general properties of other open quantum system scenarios subject to treatment within a Markovian approximation.

  16. Linear and nonlinear spectroscopy from quantum master equations.

    Fetherolf, Jonathan H; Berkelbach, Timothy C

    2017-12-28

    We investigate the accuracy of the second-order time-convolutionless (TCL2) quantum master equation for the calculation of linear and nonlinear spectroscopies of multichromophore systems. We show that even for systems with non-adiabatic coupling, the TCL2 master equation predicts linear absorption spectra that are accurate over an extremely broad range of parameters and well beyond what would be expected based on the perturbative nature of the approach; non-equilibrium population dynamics calculated with TCL2 for identical parameters are significantly less accurate. For third-order (two-dimensional) spectroscopy, the importance of population dynamics and the violation of the so-called quantum regression theorem degrade the accuracy of TCL2 dynamics. To correct these failures, we combine the TCL2 approach with a classical ensemble sampling of slow microscopic bath degrees of freedom, leading to an efficient hybrid quantum-classical scheme that displays excellent accuracy over a wide range of parameters. In the spectroscopic setting, the success of such a hybrid scheme can be understood through its separate treatment of homogeneous and inhomogeneous broadening. Importantly, the presented approach has the computational scaling of TCL2, with the modest addition of an embarrassingly parallel prefactor associated with ensemble sampling. The presented approach can be understood as a generalized inhomogeneous cumulant expansion technique, capable of treating multilevel systems with non-adiabatic dynamics.

  17. Design, Implementation and Testing of Master Slave Robotic Surgical System

    Directory of Open Access Journals (Sweden)

    Syed Amjad Ali

    2015-01-01

    Full Text Available The autonomous manipulation of the medical robotics is needed to draw up a complete surgical plan in development. The autonomy of the robot comes from the fact that once the plan is drawn up off-line, it is the servo loops, and only these, that control the actions of the robot online, based on instantaneous control signals and measurements provided by the vision or force sensors. Using only these autonomous techniques in medical and surgical robotics remain relatively limited for two main reasons: Predicting complexity of the gestures, and human Safety. Therefore, Modern research in haptic force feedback in medical robotics is aimed to develop medical robots capable of performing remotely, what a surgeon does by himself. These medical robots are supposed to work exactly in the manner that a surgeon does in daily routine. In this paper the master slave tele-robotic system is designed and implemented with accuracy and stability by using 6DOF (Six Degree of Freedom haptic force feedback devices. The master slave control strategy, haptic devices integration, application software designing using Visual C++ and experimental setup are considered. Finally, results are presented the stability, accuracy and repeatability of the system

    Krisko, Paula H.; Flegel, S.

    2010-01-01

    The latest versions of the two premier orbital debris engineering models, NASA s ORDEM2010 and ESA s MASTER-2009, have been publicly released. Both models have gone through significant advancements since inception, and now represent the state-of-the-art in orbital debris knowledge of their respective agencies. The purpose of these models is to provide satellite designers/operators and debris researchers with reliable estimates of the artificial debris environment in near-Earth orbit. The small debris environment within the size range of 1 mm to 1 cm is of particular interest to both human and robotic spacecraft programs. These objects are much more numerous than larger trackable debris but are still large enough to cause significant, if not catastrophic, damage to spacecraft upon impact. They are also small enough to elude routine detection by existing observation systems (radar and telescope). Without reliable detection the modeling of these populations has always coupled theoretical origins with supporting observational data in different degrees. This paper details the 1 mm to 1 cm orbital debris populations of both ORDEM2010 and MASTER-2009; their sources (both known and presumed), current supporting data and theory, and methods of population analysis. Fluxes on spacecraft for chosen orbits are also presented and discussed within the context of each model.

    Robotic-assisted minimally invasive surgery (MIS) can benefit both patients and surgeons. However, the learning curve for robotically assisted procedures can be long and the total system costs are high. Therefore, there is considerable interest in new methods and lower cost controllers for a surgical robotic system. In this study, a knife-master and a forceps-master, shaped similarly to a surgical knife and forceps, were developed as input devices for control of a master-slave surgical robotic system. In addition, a safety strategy was developed to eliminate the master-slave orientation difference and stabilize the surgical system. Master-slave tracking experiments and a ring-and-bar experiment showed that the safety tracking strategy could ensure that the robot system moved stably without any tremor in the tracking motion. Subjects could manipulate the surgical tool to achieve the master-slave operation with less training compared to a mechanical master. Direct manipulation of the small, light and low-cost surgical tools to control a robotic system is a possible operating mode. Surgeons can operate the robotic system in their own familiar way, without long training. The main potential safety issues can be solved by the proposed safety control strategy.

    This paper presents a novel 4-degrees-of-freedom (4-DOF) haptic master using a electrorheological (ER) fluid which is applicable to minimally invasive surgery (MIS) systems. By adopting a controllable ER fluid, the master can easily generate 4-DOF repulsive forces with the advantages of a simple mechanism and continuous force control capability. The proposed master consists of two actuators: an ER spherical joint for 3-DOF rotational motion and an ER piston device for 1-DOF translational motion. The generated torque/force models are mathematically derived by analyzing the mechanism geometry and using the Bingham characteristics of an ER Fluid. The haptic master is optimally designed and manufactured based on the mathematical torque/force models. The repulsive torque/force responses are experimentally evaluated and expressed by the first-order and second-order dynamic equations for each motion. A sliding mode controller (SMC), which is known to be robust to uncertainties, is then designed and empirically implemented to achieve the desired torque/force trajectories. It is demonstrated by presenting torque/force tracking results of both rotational and translational motions that the proposed 4-DOF ER haptic master integrated with the SMC can provide an effective haptic control performance for MIS applications.

    Reaching high density in PM steels is important for high-performance applications. In this study, liquid phase sintering of PM steels by adding gas-atomized Ni-Mn-B master alloy was investigated for enhancing the density levels of Fe- and Mo- prealloyed steel powder compacts. The results indicated that liquid formation occurs in two stages, beginning with the master alloy melting (LP-1) below and eutectic phase formation (LP-2) above 1373 K (1100 °C). Mo and C addition revealed a significant influence on the LP-2 temperatures and hence on the final densification behavior and mechanical properties. Microstructural embrittlement occurs with the formation of continuous boride networks along the grain boundaries, and its severity increases with carbon addition, especially for 2.5 wt pct of master alloy content. Sintering behavior, along with liquid generation, microstructural characteristics, and mechanical testing revealed that the reduced master alloy content from 2.5 to 1.5 wt pct (reaching overall boron content from 0.2 to 0.12 wt pct) was necessary for obtaining good ductility with better mechanical properties. Sintering with Ni-Mn-B master alloy enables the sintering activation by liquid phase formation in two stages to attain high density in PM steels suitable for high-performance applications.

  2. INTERNATIONAL IMMERSION: AN EVALUATION BY EXCHANGE STUDENTS FROM PROFESSIONAL MASTER

    Full Text Available The internationalization of university courses involves the flow of people, information and possibly resources that move in the direction of foreign institutions with which it maintains academic cooperation ties, as in the opposite direction. This process can lead to academic advantages by improving training, education and research in the institution, and needs to be continuously assessed in order to improve its benefits. Therefore, this work presents an evaluation of international immersion initiative of a professional master's degree according the perception of the student. After 15 days of activities in Portugal, 26 students answered a questionnaire related to the effectiveness of the immersion program. In general, the results indicated a contribution extremely important for most activities, pointing to a benefit/cost relation favorable of the activity. The main difficulty pointed out by students for participation in the immersion was related to restrictions and bureaucracy to obtain resources in their work institutions.

    Full Text Available This article looks at the life of Japanese/Canadian karate pioneer, Masaru Shintani, from his birth in Vancouver, British Columbia, until his death in Kapuskasing, Ontario. After more than thirty years of teaching, Shintani created one of the largest karate organizations in North America with over 27,000 members. Shintani also invented Shindo, a martial art facilitating the use of an ancient weapon, the short stick, with modern techniques. For this article, many of Shintani’s senior students helped to reconstruct his life and explain his complex personality with recollections of their teacher. From the beginning of his karate training in an internment camp, to the eventual achievement of 9th-degree black belt, Masaru Shintani epitomized the modern karate master.

  8. A master functional for quantum field theory

    We study a new generating functional of one-particle irreducible diagrams in quantum field theory, called master functional, which is invariant under the most general perturbative changes of field variables. The usual functional {Gamma} does not behave as a scalar under the transformation law inherited from its very definition as the Legendre transform of W=lnZ, although it does behave as a scalar under an unusual transformation law. The master functional, on the other hand, is the Legendre transform of an improved functional W with respect to the sources coupled to both elementary and composite fields. The inclusion of certain improvement terms in W and Z is necessary to make this new Legendre transform well defined. The master functional behaves as a scalar under the transformation law inherited from its very definition. Moreover, it admits a proper formulation, obtained extending the set of integrated fields to so-called proper fields, which allows us to work without passing through Z, W or {Gamma}. In the proper formulation the classical action coincides with the classical limit of the master functional, and correlation functions and renormalization are calculated applying the usual diagrammatic rules to the proper fields. Finally, the most general change of field variables, including the map relating bare and renormalized fields, is a linear redefinition of the proper fields. (orig.)

    Evaluation of the predictive validity of selected sociodemographic factors and admission criteria for Master's studies in Public Health at the Faculty of Health Sciences, Medical University of Warsaw (MUW). For the evaluation purposes recruitment data and learning results of students enrolled between 2008 and 2012 were used (N = 605, average age 22.9 ± 3.01). The predictive analysis was performed using the multiple linear regression method. In the proposed regression model 12 predictors were selected, including: sex, age, professional degree (BA), the Bachelor's studies grade point average (GPA), total score of the preliminary examination broken down into five thematic areas. Depending on the tested model, one of two dependent variables was used: first-year GPA or cumulative GPA in the Master program. The regression model based on the result variable of Master's GPA program was better matched to data in comparison to the model based on the first year GPA (adjusted R2 0.413 versus 0.476 respectively). The Bachelor's studies GPA and each of the five subtests comprising the test entrance exam were significant predictors of success achieved by a student both after the first year and at the end of the course of studies. Criteria of admissions with total score of MCQs exam and Bachelor's studies GPA can be successfully used for selection of the candidates for Master's degree studies in Public Health. The high predictive validity of the recruitment system confirms the validity of the adopted admission policy at MUW.

    Whether degrees are essential for emergency nurses, is a question that seems to exercise lots of people these days. Certainly there is a view that to be a nurse you need kind hands and a warm heart and that's about enough. Nursing is seen by some as an academically pedestrian activity and there are plenty who believe that degrees for nurses are a waste of time in every sense. After all, the argument runs, surely you don't need a degree to give out bedpans. Given that the vast majority of nurses are- women, the argument against degrees does have a rather sexist undertone to it a lot of the time.

    2012-07-01

    Full Text Available Abstract Background Stochastic biochemical reaction networks are commonly modelled by the chemical master equation, and can be simulated as first order linear differential equations through a finite state projection. Due to the very high state space dimension of these equations, numerical simulations are computationally expensive. This is a particular problem for analysis tasks requiring repeated simulations for different parameter values. Such tasks are computationally expensive to the point of infeasibility with the chemical master equation. Results In this article, we apply parametric model order reduction techniques in order to construct accurate low-dimensional parametric models of the chemical master equation. These surrogate models can be used in various parametric analysis task such as identifiability analysis, parameter estimation, or sensitivity analysis. As biological examples, we consider two models for gene regulation networks, a bistable switch and a network displaying stochastic oscillations. Conclusions The results show that the parametric model reduction yields efficient models of stochastic biochemical reaction networks, and that these models can be useful for systems biology applications involving parametric analysis problems such as parameter exploration, optimization, estimation or sensitivity analysis.

  11. Lessons learned from a great master!

    Directory of Open Access Journals (Sweden)

    Wagner Seixas da Silva

    2015-06-01

    Full Text Available Teaching Biochemistry is a huge challenge in the basic cycle of many undergraduate courses. How to convince students that this discipline is important for their academic degree so early in their college journeys? It may be hard to define in words a good teaching strategy for this purpose, but during the 70s'/80's a group of professors accepted this tough task! Professor Leopoldo de Meis paid particular attention to the way of teaching biochemistry. As a very sensitive person, he realized that the secret to a good teaching would be to keep the students motivated with doses of challenge.With this in mind, Prof. de Meis joined a small group of professors and graduate students from the former Department of Medical Biochemistry, now named Institute of Medical Biochemistry Leopoldo de Meis, at the Federal University of Rio de Janeiro, and proposed to use the Discovery learning method in classroom. The idea was to present the contents of the biochemistry course while challenging students to interpret the original data of the major biochemical findings. For this purpose, each biochemistry theme was shown through the experiments that led to the originally obtained conclusions currently present in the textbooks. Thus, students were motivated to ask questions and propose experiments that allow the interpretation of the scientists’ historical results. At first the methodology seemed very novel and difficult, but over the first few minutes the environment became a place for broad scientific discussion, where students enthusiastically participated and developed the ability to draw up the necessary questions to decipher the functioning of metabolic pathways. The parallel between the observed experimental facts and the physiological state of the experimental model used in classic experiments permitted the development of a broad and critical knowledge in the learning of biochemistry.To imagine that the students were motivated to develop the autonomy of

    This paper considers conditional Gaussian networks. The parameters in the network are learned by using conjugate Bayesian analysis. As conjugate local priors, we apply the Dirichlet distribution for discrete variables and the Gaussian-inverse gamma distribution for continuous variables, given...... a configuration of the discrete parents. We assume parameter independence and complete data. Further, to learn the structure of the network, the network score is deduced. We then develop a local master prior procedure, for deriving parameter priors in these networks. This procedure satisfies parameter...... independence, parameter modularity and likelihood equivalence. Bayes factors to be used in model search are introduced. Finally the methods derived are illustrated by a simple example....

    Full Text Available In this article I analyse the performative dimension that constitutes the transmission of tradition in taoist lineage located in Brazil, from the perspective of the anthropology of experience. The idea of knowing in taoism is based on a practical notion: one knows the legacy of tradition through personal embodied experience. The very possibility of knowing is based upon a personal relation between master and apprentice, inserted on a dialogical and genealogical.

    2013-10-01

    Full Text Available This article describes how the craftsmen at the workroom at Handarbetets vänner, Stockholm, learned their craft skills during the years 1948‒2012. What this knowledge consisted of and how the apprentices’ knowledge grows into skillfulness. Interviews with 15 weavers and embroiderers who have worked during the time period form the empirical material. The period of time was chosen according to the informants´ times of employment.The strategies for learning are affected by dialogue between the craftsmen, both a verbal and a silent dialogue. The dialogue is an important part of the learning even though the making is central. The workroom forms its own way of making textile art, a way of doing that is learned from master to apprentice. In this situated knowledge, the different masters have their own ways of for instance mixing color and material, all corresponding with core values. The learning is also affected by the artistic leader and the artist.The learning within the workroom occurs in the making of objects, but never at the cost of the quality of the objects. The core values of the establishments, and the fact that there is a strive to be profitable, makes the circumstances. The collaboration with the artist in creating unique textile art is the primary goal; the learning is something that is taken for granted in order to withhold the competence in the establishment.Keywords: textile craft, master and apprentice, craftsmen, textile art, workroom

    Pacing strategies are key to overall performance outcome in distance running events. Presently, no literature has examined pacing strategies utilised by masters athletes, of all running levels, during a competitive marathon. Therefore, this study aimed to examine masters athletes' pacing strategies, categorised by gender, age and performance level. Data were retrieved from the 2015 TSC New York City Marathon for 31,762 masters athletes (20,019 men and 11,743 women). Seven performance classification (PC) groupings were identified via comparison of overall completion time compared to current world records, appropriate to age and gender. Data were categorised via, age, gender, and performance level. Mean 5 km speed for the initial 40 km was calculated and the fastest and slowest 5 km split speeds were identified and expressed as a percentage faster or slower than mean speed. Pace range, calculated as the absolute sum of the fastest and slowest split percentages, was then analysed. Significant main effects were identified for age, gender and performance level (p effect was found for gender×performance (p marathon, independent of age and gender.

    Boman, Katarina; Thomas, Jean; Funkquist, Jonas

    2010-08-15

    The main goal of the project has been to evaluate the potential of a coordinated master control for a solid fuel power plant in terms of tracking capability, stability and robustness. The control strategy has been model-based predictive control (MPC) and the plant used in the case study has been the Vattenfall power plant Idbaecken in Nykoeping. A dynamic plant model based on nonlinear physical models was used to imitate the true plant in MATLAB/SIMULINK simulations. The basis for this model was already developed in previous Vattenfall internal projects, along with a simulation model of the existing control implementation with traditional PID controllers. The existing PID control is used as a reference performance, and it has been thoroughly studied and tuned in these previous Vattenfall internal projects. A turbine model was developed with characteristics based on the results of steady-state simulations of the plant using the software EBSILON. Using the derived model as a representative for the actual process, an MPC control strategy was developed using linearization and gain-scheduling. The control signal constraints (rate of change) and constraints on outputs were implemented to comply with plant constraints. After tuning the MPC control parameters, a number of simulation scenarios were performed to compare the MPC strategy with the existing PID control structure. The simulation scenarios also included cases highlighting the robustness properties of the MPC strategy. From the study, the main conclusions are: - The proposed Master MPC controller shows excellent set-point tracking performance even though the plant has strong interactions and non-linearity, and the controls and their rate of change are bounded. - The proposed Master MPC controller is robust, stable in the presence of disturbances and parameter variations. Even though the current study only considered a very small number of the possible disturbances and modelling errors, the considered cases are

    2014-01-01

    : Numerous medical schools currently offer a master of arts (MA) in bioethics dual degree for physicians. A degree in bioethics enhances the care physicians provide to patients and prepares physicians to serve on ethics committees and consult services. Additionally, they may work on institutional and public policy issues related to ethics. Several physician assistant (PA) programs currently offer a master of public health (MPH) dual degree for PAs. A degree in public health prepares PAs for leadership roles in meeting community health needs. With the success of PA/MPH dual degree programs, we argue here that a PA/bioethics dual degree would be another opportunity to advance the PA profession and consider how such a program might be implemented. The article includes the individual perspectives of the authors, one of whom completed a graduate-level certificate in bioethics concurrently with his 2-year PA program, while the other served as a bioethics program director.

    Citation between papers can be treated as a causal relationship. In addition, some citation networks have a number of similarities to the causal networks in network cosmology, e.g., the similar in-and out-degree distributions. Hence, it is possible to model the citation network using network cosmology. The casual network models built on homogenous spacetimes have some restrictions when describing some phenomena in citation networks, e.g., the hot papers receive more citations than other simultaneously published papers. We propose an inhomogenous causal network model to model the citation network, the connection mechanism of which well expresses some features of citation. The node growth trend and degree distributions of the generated networks also fit those of some citation networks well.

    Wang, Lei; Xu, Qingzheng

    2010-01-01

    Localization is one of the most fundamental problems in wireless sensor networks, since the locations of the sensor nodes are critical to both network operations and most application level tasks. A GPS-free localization scheme for wireless sensor networks is presented in this paper. First, we develop a standardized clustering-based approach for the local coordinate system formation wherein a multiplication factor is introduced to regulate the number of master and slave nodes and the degree of connectivity among master nodes. Second, using homogeneous coordinates, we derive a transformation matrix between two Cartesian coordinate systems to efficiently merge them into a global coordinate system and effectively overcome the flip ambiguity problem. The algorithm operates asynchronously without a centralized controller; and does not require that the location of the sensors be known a priori. A set of parameter-setting guidelines for the proposed algorithm is derived based on a probability model and the energy requirements are also investigated. A simulation analysis on a specific numerical example is conducted to validate the mathematical analytical results. We also compare the performance of the proposed algorithm under a variety multiplication factor, node density and node communication radius scenario. Experiments show that our algorithm outperforms existing mechanisms in terms of accuracy and convergence time.

  19. Normalized modularity optimization method for community identification with degree adjustment.

    Zhang, Shuqin; Zhao, Hongyu

    2013-11-01

    As a fundamental problem in network study, community identification has attracted much attention from different fields. Representing a seminal work in this area, the modularity optimization method has been widely applied and studied. However, this method has issues in resolution limit and extreme degeneracy and may not perform well for networks with unbalanced structures. Although several methods have been proposed to overcome these limitations, they are all based on the original idea of defining modularity through comparing the total number of edges within the putative communities in the observed network with that in an equivalent randomly generated network. In this paper, we show that this modularity definition is not suitable to analyze some networks such as those with unbalanced structures. Instead, we propose to define modularity through the average degree within the communities and formulate modularity as comparing the sum of average degree within communities of the observed network to that of an equivalent randomly generated network. In addition, we also propose a degree-adjusted approach for further improvement when there are unbalanced structures. We analyze the theoretical properties of our degree adjusted method. Numerical experiments for both artificial networks and real networks demonstrate that average degree plays an important role in network community identification, and our proposed methods have better performance than existing ones.

    2012-01-01

    Until 1996, there were only 7 masters-level programs in health professions education (HPE); currently, there are 76 such programs. The purpose of this article is to provide information and perspectives about the available masters programs in HPE worldwide, with a focus on their mission, objectives, content, instructional strategies, format, duration, and cost, as well as the similarities and differences among them. A literature and web search was conducted to develop a complete list of programs that offer a masters degree in HPE or closely related areas. Forty three percent [43% (33)] of these programs are in Europe, 20% (15) in North America, 17% (13) in Asia, 7% (5) in Latin America, 5% (4) in the Middle East, 5% (4) in Australia, and 3% (2) in Africa. The mission of these masters programs is to prepare leaders in HPE or sometimes narrowly focusing on clinical or dental education. The content is addressed in core courses and electives, generally grouped under the following headings: curriculum development, instructional methods/teaching and learning, assessment strategies, program evaluation, research design, and sometimes leadership and management. Medical schools sponsor approximately two-thirds of these programs, and the average duration for completion is 2 years. The vast majority of these programs are offered in English. The commonalities among these programs include focus, content, and educational requirements. The variations are mostly in organization and structure. There is a need to establish criteria and mechanisms for evaluation of these programs. The geographic maldistribution of these programs is a major concern.

    Compared with conventional minimally invasive surgery and open surgery, robotic-assisted minimally invasive surgery can overcome or eliminate drawbacks caused by operator restrictions, motion limitation by the trocar and the image system, such as fatigue, trembling, low precision, constrained degree-of-freedom, poor hand-eye coordination and restricted surgical vision. In this paper, a novel partly tendon-driven master-slave robot system is proposed to assist minimally invasive surgery and a master-slave control architecture is developed for abdominal surgical operations. A novel master-slave surgery robot system named MicroHand A has been developed. A kinematic analysis of master and slave manipulators was conducted, based on screw theory and vector loop equation. The relationships of the tendon-driven multi-DOF surgical instrument among Cartesian space, actuator space and joint space were derived for control purposes. The control system architecture of the MicroHand A was designed with intuitive motion control and motion scaling control. Llewellyn's absolute stability criterion and the transparency of the one-DOF master-slave system are also analysed. Intuitive motion control under dissimilar kinematics in master-slave manipulations and motion scaling control were accomplished to solve absonant hand-eye coordination, kinematic dissimilarity and workspace mismatch of master-slave manipulator problems. A series of tests and animal experiments were carried out to evaluate system performance. The experimental results demonstrate that the system could accomplish intuitive motion control and motion scaling control, and that the control system is stable and reliable. The experiments performed on the MicroHand A robotic system yielded expected control results. The system satisfies the requirements of minimally invasive surgery. Intuitive motion control and motion scaling control under different kinematics for the master and slave have been implemented. Copyright © 2011

  4. High-Degree Neurons Feed Cortical Computations.

    2016-05-01

    Full Text Available Recent work has shown that functional connectivity among cortical neurons is highly varied, with a small percentage of neurons having many more connections than others. Also, recent theoretical developments now make it possible to quantify how neurons modify information from the connections they receive. Therefore, it is now possible to investigate how information modification, or computation, depends on the number of connections a neuron receives (in-degree or sends out (out-degree. To do this, we recorded the simultaneous spiking activity of hundreds of neurons in cortico-hippocampal slice cultures using a high-density 512-electrode array. This preparation and recording method combination produced large numbers of neurons recorded at temporal and spatial resolutions that are not currently available in any in vivo recording system. We utilized transfer entropy (a well-established method for detecting linear and nonlinear interactions in time series and the partial information decomposition (a powerful, recently developed tool for dissecting multivariate information processing into distinct parts to quantify computation between neurons where information flows converged. We found that computations did not occur equally in all neurons throughout the networks. Surprisingly, neurons that computed large amounts of information tended to receive connections from high out-degree neurons. However, the in-degree of a neuron was not related to the amount of information it computed. To gain insight into these findings, we developed a simple feedforward network model. We found that a degree-modified Hebbian wiring rule best reproduced the pattern of computation and degree correlation results seen in the real data. Interestingly, this rule also maximized signal propagation in the presence of network-wide correlations, suggesting a mechanism by which cortex could deal with common random background input. These are the first results to show that the extent to

    A quantum fluctuation theorem for a driven quantum subsystem interacting with its environment is derived based solely on the assumption that its reduced density matrix obeys a closed evolution equation--i.e., a quantum master equation (QME). Quantum trajectories and their associated entropy, heat, and work appear naturally by transforming the QME to a time-dependent Liouville space basis that diagonalizes the instantaneous reduced density matrix of the subsystem. A quantum integral fluctuation theorem, a steady-state fluctuation theorem, and the Jarzynski relation are derived in a similar way as for classical stochastic dynamics.

    2003-01-01

    This book presents a new degree theory for maps which commute with a group of symmetries. This degree is no longer a single integer but an element of the group of equivariant homotopy classes of maps between two spheres and depends on the orbit types of the spaces. The authors develop completely the theory and applications of this degree in a self-contained presentation starting with only elementary facts. The first chapter explains the basic tools of representation theory, homotopy theory and differential equations needed in the text. Then the degree is defined and its main abstract properties are derived. The next part is devoted to the study of equivariant homotopy groups of spheres and to the classification of equivariant maps in the case of abelian actions. These groups are explicitely computed and the effects of symmetry breaking, products and composition are thorougly studied. The last part deals with computations of the equivariant index of an isolated orbit and of an isolated loop of stationary point...

    Theses are the prime indicators of the scientific productivity of a country and one of the main and strongest resources for the emergence of scientific articles. This study aims to examine, by using the survey method, how many of the audiology master and/or doctoral theses in Turkey were turned into a scientific work. Individuals who received a master's degree in audiology were surveyed whether their theses had been reviewed as a paper or publication. Forty-five of the 230 audiology specialists and 22 audiologists with a doctorate degree working in Turkey participated in the study by answering the survey questions. In general, while 45.4% of master theses were presented orally or as a poster presentation in a national convention, 20.4% were presented orally or as a poster presentation in an international convention. While 18.1% of theses were published as an article in a national journal, 15.9% were published as an article in an international SCI or SCI-E journal. The distribution of the doctoral theses is 26.6%, 33.3%, 13.3% and 26.6%, respectively. We found the rate of theses in audiology turning into a scientific article to be below the desired level, as in other fields. The reasons for this should be emphasized and efforts should be made to raise these rates to the desired level.

    In our current era, society needs an increased representation of physicists in the workforce to help solve the growing number of societal and environment problems we collectively face. And even though a physics bachelor's degree opens the door to an incredible diversity of high-paying and rewarding careers, most undergraduates are only aware of academic career paths (having mostly encountered only physics professors during their lifetime). This talk will provide in-depth information about physics career paths outside of academia which available to those with a bachelor's degree in physics, and will discuss how these options change as one moves through an advanced degree in physics. The talk will include real-life examples of working physicists at all stages of the degree path, and salary and employment sector statistics for physics bachelors, masters, and PhD recipients. The talk will also include information on additional careers and professional development resources for students.

  1. Percolation in clustered networks

    OpenAIRE

    Miller, Joel C

    2009-01-01

    The social networks that infectious diseases spread along are typically clustered. Because of the close relation between percolation and epidemic spread, the behavior of percolation in such networks gives insight into infectious disease dynamics. A number of authors have studied clustered networks, but the networks often contain preferential mixing between high degree nodes. We introduce a class of random clustered networks and another class of random unclustered networks with the same prefer...

  2. Communication: Master equations for electron transport: The limits of the Markovian limit.

    Elenewski, Justin E; Gruss, Daniel; Zwolak, Michael

    2017-10-21

    Master equations are increasingly popular for the simulation of time-dependent electronic transport in nanoscale devices. Several recent Markovian approaches use "extended reservoirs"-explicit degrees of freedom associated with the electrodes-distinguishing them from many previous classes of master equations. Starting from a Lindblad equation, we develop a common foundation for these approaches. Due to the incorporation of explicit electrode states, these methods do not require a large bias or even "true Markovianity" of the reservoirs. Nonetheless, their predictions are only physically relevant when the Markovian relaxation is weaker than the thermal broadening and when the extended reservoirs are "sufficiently large," in a sense that we quantify. These considerations hold despite complete positivity and respect for Pauli exclusion at any relaxation strength.

    The Spanish University System in the framework of the European studies under the Bologna process presents a huge number of Master courses. This fact has yielded the creation of an official procedure of "accreditation" of this kind of degrees. In this work, we present and discuss data collected from the official accreditation process recently carried out for the Masters on "Photonics and Laser Technologies", coordinated by the University of Vigo (UVigo) and involving three Universities: Vigo (UVIGO), Santiago de Compostela (USC) and A Coruña (UdC) in the autonomous region of Galicia (Spain) where the accreditation is made by the Agency for the Quality of the University Galician System (ACSUG). The data collected play a fundamental role in the accreditation process in order to make future decisions about the studies offered in the Galician University System.

  4. McMaster Mesonet soil moisture dataset: description and spatio-temporal variability analysis

    2013-04-01

    Full Text Available This paper introduces and describes the hourly, high-resolution soil moisture dataset continuously recorded by the McMaster Mesonet located in the Hamilton-Halton Watershed in Southern Ontario, Canada. The McMaster Mesonet consists of a network of time domain reflectometer (TDR probes collecting hourly soil moisture data at six depths between 10 cm and 100 cm at nine locations per site, spread across four sites in the 1250 km2 watershed. The sites for the soil moisture arrays are designed to further improve understanding of soil moisture dynamics in a seasonal climate and to capture soil moisture transitions in areas that have different topography, soil and land cover. The McMaster Mesonet soil moisture constitutes a unique database in Canada because of its high spatio-temporal resolution. In order to provide some insight into the dominant processes at the McMaster Mesonet sites, a spatio-temporal and temporal stability analysis were conducted to identify spatio-temporal patterns in the data and to suggest some physical interpretation of soil moisture variability. It was found that the seasonal climate of the Great Lakes Basin causes a transition in soil moisture patterns at seasonal timescales. During winter and early spring months, and at the meadow sites, soil moisture distribution is governed by topographic redistribution, whereas following efflorescence in the spring and summer, soil moisture spatial distribution at the forested site was also controlled by vegetation canopy. Analysis of short-term temporal stability revealed that the relative difference between sites was maintained unless there was significant rainfall (> 20 mm or wet conditions a priori. Following a disturbance in the spatial soil moisture distribution due to wetting, the relative soil moisture pattern re-emerged in 18 to 24 h.

    Carl, Janet E.

    Researchers have shown that women remain underrepresented in the sciences particularly in doctorate degree attainment. This investigator aimed to extend previous research by examining possible causes of gender disparity in science graduate education using data from the Baccalaureate and Beyond Longitudinal Study, B&B.:93/03. Variables in categories of demographics, academic achievement, financial resources, degree expectations and attitudes toward educational experiences, future study and employment were analyzed by t tests and hierarchical regression to determine gender differences in graduate degree expectations and attainment by male and female science majors. Findings supported gender disparity in undergraduate and graduate fields of study. Women dominated health areas and earned terminal master's degrees, whereas men dominated the physical science field and attained a higher proportion of doctorate degrees. Results also showed no gender differences in master's degree attainment in other fields thus confirming that these graduates did not persist in science fields. Graduate degree expectation was a strong predictor for master's and doctorate degree attainment. Parent education had a significant effect on degree expectations but not on graduate degree attainment. Women tended to have lower degree expectations and earned fewer science and math credits than men. Results showed that unemployment and loans predicted doctorate degree attainment by men and women showed higher levels of employment in graduate school.

    2011-01-01

    Full Text Available In recent years, new surgical tools have been designed to improve treatment results and lower patient trauma. Nevertheless, the dexterity and accuracy required for the positioning of new tools are often unreachable, if surgeons are not assisted by suitable systems. Significant advantages are derived from the introduction of computer and robot technologies. For that reason, the interaction between robotic systems and surgeons today is producing new interest worldwide both in medical and engineering fields. In particular, medical robotics has found fruitful ground in neurosurgical applications, since the high functional density of the central nervous system requires strict accuracy constraints on tool positioning. As a matter of fact, the major benefits of robots, such as precision, accuracy and repeatability, make them ideal as neurosurgeons’ assistants. This paper presents a master-slave haptic robotic system for minimally invasive neurosurgery, which can aid surgeons in performing safer and more accurate stereotactic neurosurgical treatments. The design of the proposed system is based on LANS (Linear Actuator for NeuroSurgery, which has been developed by our Research Group. Experimental test aimed at showing the added value of the DAANS system over its predecessor, the effectiveness of conformational caps and of the added rotational degree of freedom are scheduled for the upcoming months.

    Argonne National Laboratory has prepared a master environmental plan (MEP) for Fort Devens, Massachusetts, for the US Army Toxic and Hazardous Materials Agency. The MEP is an assessment based on environmental laws and regulations of both the federal government and the Commonwealth of Massachusetts. The MEP assess the physical and environmental status of 58 potential hazardous waste sites, including 54 study areas (SAs) that pose a potential for releasing contamination into the environment and 4 areas of concern (AOCs) that are known to have substantial contamination. For each SA or AOC, this MEP describes the known history and environment, identifies additional data needs, and proposes possible response actions. Most recommended response actions consist of environmental sampling and monitoring and other characterization studies. 74 refs., 63 figs., 50 tabs.

    2014-12-01

    In 2007, the Department of Natural Resources and Environmental Science established the first undergraduate degree in Ecohydrology in the United States. The degree was designed to prepare students for careers as hydrologists while also including coursework equivalent to a minor in ecology (UNR does not officially offer a minor in ecology). The development of the major was intended to provide students with useful skills and training for the job market, and also to increase enrollment in the University's water-related undergraduate majors. The Department also established an Ecohydrology minor. Since the degree was established, average enrollment in the major has been almost two times higher than the previous Watershed Science option in Environmental Science (the closest comparable degree offering at UNR). The Department has graduated 19 students as of May 2014, and an additional 8 students have graduated with the Ecohydrology minor. Several Ecohydrology graduates have gone on to graduate degrees, and most of the remainder are employed in water-related areas. The students have established an Ecohydrology Club at UNR and are active in organizing water-related activities to do together. This presentation will describe the development of the degree, its implementation, and challenges and opportunities for carrying out an undergraduate degree in Ecohydrology. It will also discuss potential development of a 5-year Bachelor of Science-Master of Science (BS-MS) degree in Ecohydrology.

  10. Transparent Higher Order Sliding Mode Control for Nonlinear Master-Slave Systems without Velocity Measurement

    Directory of Open Access Journals (Sweden)

    Luis G. Garcia-Valdovinos

    2015-04-01

    Full Text Available Transparency has been a major objective in bilateral teleoperation systems, even in the absence of time delay induced by the communication channel, since a high degree of transparency would allow humans to drive the remote teleoperator as if he or she were directly interacting with the remote environment, with the remote teleoperator as a physical and sensorial extension of the operator. When fast convergence of position and force tracking errors are ensured by the control system, then complete transparency is obtained, which would ideally guarantee humans to be tightly kinaesthetically coupled. In this paper a model-free Cartesian second order sliding mode (SOSM PD control scheme for nonlinear master-slave systems is presented. The proposed scheme does not rely on velocity measurements and attains very fast convergence of position trajectories, with bounded tracking of force trajectories, rendering a high degree of transparency with lesser knowledge of the system. The degree of transparency can easily be improved by tuning a feedback gain in the force loop. A unique energy storage function is introduced; such that a similar Cartesian-based controller is implemented in the master and slave sides. The resulting properties of the Cartesian control structure allows the human operator to input directly Cartesian variables, which makes clearer the kinaesthetic coupling, thus the proposed controller becomes a suitable candidate for practical implementation. The performance of the proposed scheme is evaluated in a semi-experimental setup.

    2014-01-01

    The latest versions of the two premier orbital debris engineering models, NASA's ORDEM 3.0 and ESA's MASTER-2009, have been publically released. Both models have gone through significant advancements since inception, and now represent the state-of-the-art in orbital debris knowledge of their respective agencies. The purpose of these models is to provide satellite designers/operators and debris researchers with reliable estimates of the artificial debris environment in low Earth orbit (LEO) to geosynchronous orbit (GEO). The small debris environment within the size range of 1 mm to 1 cm is of particular interest to both human and robotic spacecraft programs, particularly in LEO. These objects are much more numerous than larger trackable debris and can have enough momentum to cause significant, if not catastrophic, damage to spacecraft upon impact. They are also small enough to elude routine detection by existing observation systems (radar and telescope). Without reliable detection the modeling of these populations has always coupled theoretical origins with supporting observational data in different degrees. In this paper, we present and detail the 1 mm to 1 cm orbital debris populations from both ORDEM 3.0 and MASTER-2009 in LEO. We review population categories: particle sources for MASTER-2009, particle densities for ORDEM 3.0. We describe data sources and their uses, and supporting models. Fluxes on spacecraft for chosen orbits are also presented and discussed within the context of each model.

    2009-08-01

    In 2003, Meijo University has developed a new program to train students in master's degree in the field of clinical practice. This new curriculum has three big pillars of educational goal: Problem-Based Learning (PBL), communication skill and clinical pharmacy practice training. Before exposing students to clinical training, they must learn first how to solve various patients' problems through PBL and enhance their communication skill. To provide a clinical environment, education and training, the Faculty of Pharmacy cooperated with the School of Medicine of Fujita Health University. Master's students together with other members of the healthcare team observe patient's disease state and most especially monitor pharmacotherapy. At first, students will be trained for a month at the pharmacy division and experience one week-nursing job. Next, they will be trained at the clinical divisions such as General Internal Medicine, Cardiology, Endocrinology, Gastroenterology, Respiratory Medicine, Hematology, Chemotherapy, Gastroenterological Surgery, Psychiatry, and Emergency Unit. Students rotate three-month training on four clinical divisions during one year. The head physicians of the medical department hold concurrent post as professors and share responsibility with the pharmacy faculty in training the students. To have its venue where students, faculty and physicians conduct their discussion on clinical cases, a pharmacy satellite seminar class room was set up at Fujita Health University hospital. Through this, pharmacy students and faculty had more opportunities to exchange knowledge on medicine and pharmacy. Master's students are expected to acquire professionalism, ethical knowledge and pharmaceutical care skills through the clinical pharmacy practice program.

    The health systems in developing countries face challenges because of deficient monitoring and evaluation (M&E) capacity with respect to their knowledge, skills, and practices. Strengthening M&E training in public health education can help overcome the gaps in M&E capacity. There is a need to advance the teaching of M&E as a core element of public health education. To review M&E teaching across Masters of Public Health programs and to identify core competencies for M&E teaching in South Asian context. We undertook two activities to understand the M&E teaching across masters level programs: (1) desk review of M&E curriculum and teaching in masters programs globally and (2) review of M&E teaching across 10 institutions representing 4 South Asian countries. Subsequently, we used the findings of these two activities as inputs to identify core competencies for an M&E module through a consultative meeting with the 10 South Asian universities. Masters programs are being offered globally in 321 universities of which 88 offered a Masters in Public Health, and M&E was taught in 95 universities. M&E was taught as a part of another module in 49 institutions. The most common duration of M&E teaching was 4-5 weeks. From the 70 institutes where information on electives was available, M&E was a core module/part of a core module at 42 universities and an elective at 28 universities. The consultative meeting identified 10 core competencies and draft learning objectives for M&E teaching in masters programs in South Asia. The desk review showed similarities in M&E course content but variations in course structure and delivery. The core competencies identified during the consultation included basic M&E concepts. The results of the review and the core competencies identified at the consultation are useful resources for institutions interested in refining/updating M&E curricula in their postgraduate degree programs. Our approach for curriculum development as well as the consensus

    Full Text Available For Double Star Project (DSP exploration, the scientific operations are very important and essential for achieving its scientific objectives. Two years before the launch of the DSP satellites (TC-1 and TC-2 and during the mission operating phase, the long-term and short-term master science operations plans (MSOP were produced. MSOP is composed of the operation schedules of all the scientific instruments, the modes and timelines of the Payload Service System on TC-1 and TC-2, and the data receiving schedules of the three ground stations. The MSOP of TC-1 and TC-2 have been generated according to the scientific objectives of DSP, the orbits of DSP, the near-Earth space environments and the coordination with Cluster, etc., so as to make full use of the exploration resources provided by DSP and to acquire as much quality scientific data as possible for the scientific communities. This paper has summarized the observation resources of DSP, the states of DSP and its evolution since the launch, the strategies and rules followed for operating the payload and utilizing the ground stations, and the production of MSOP. Until now, the generation and execution of MSOP is smooth and successful, the operating of DSP is satisfactory, and most of the scientific objectives of DSP have been fulfilled.
