    Full Text Available Thisstudy addresses the factors responsible for cloud computing adoption in implementing cloud computing for any organization. Service Level Agreements play a major role for cloud consumer as well as for cloud provider. SLA depends on the requirements gathered by the cloud providers and they vary with the type of organizations for which process is being performed such as education, retail, IT industry etc. SLAs for cloud computing involves technical as well as business requirements which makes the gathering of requirements from stakeholders point of view the heterogeneous process. This research work proposes a 360 degree requirement gathering framework, which reduces the complexitiesduring the process of requirement gathering by cloud service providersas well as SLAs more reliant.

    To respond to ever increasing complexity of health care professions, education of nurses, midwives, physiotherapists, radiology engineers, and medical laboratory workers, has been upgraded to pregraduate, graduate and postgraduate university levels. In Croatia, nursing was defined as a branch of clinical medical science in 1997. Croatia and Bosnia and Herzegovina have introduced first two levels, but there is a strong need for the third one (doctoral degree). It should last three years and contain 180 ECTS points. It includes acquisition of evidence-based advanced health care, and the ability for independent research and critical analysis. Doctoral degrees in health professions are instrumental for academic careers of faculty of health professions. Yet this will not separate them from their patients or make them administrators, as the majority of their work will still be spent alongside patients.

    INTRODUCTION: I n order to assess the value of using the methotrexate information booklet, we conducted a single blind prospective controlled trial of the patients attending two rheumatology services. METHODS: The active-arm (n=40) used the MTX information booklet for the patients\\' education and the control-arm (n=38) did not. Patients\\' interviews were conducted over a 6-month period using an MTX-questionnaire. RESULTS: The entire active-arm patients (100%) were taking folic-acid and 32 (80%) knew the reason why they were taking folic-acid vs. [30 (79%) and 10 (26%) in the control-arm]. In the active-arm 35 (88%) knew the reason for their monthly blood tests vs. 18 (47%) in the control-arm. The entire active-arm was aware of the need for contraception use and MTX-side effects vs. 23 (60%) and 15 (40%) in the control-arm respectively. CONCLUSIONS: The use of the MTX information booklet in our cohort improved their understanding of the treatment.

    2010-05-01

    This Methodology Booklet provides a comprehensive review and methodology guiding principles for constructing energy efficiency indicators, with illustrative examples of application to individual countries. It reviews work done by international agencies and national government in constructing meaningful energy efficiency indicators that help policy makers to assess changes in energy efficiency over time. Building on past OECD experience and best practices, and the knowledge of these countries' institutions, relevant sources of information to construct an energy indicator database are identified. A framework based on levels of hierarchy of indicators -- spanning from aggregate, macro level to disaggregated end-use level metrics -- is presented to help shape the understanding of assessing energy efficiency. In each sector of activity: industry, commercial, residential, agriculture and transport, indicators are presented and recommendations to distinguish the different factors affecting energy use are highlighted. The methodology booklet addresses specifically issues that are relevant to developing indicators where activity is a major factor driving energy demand. A companion spreadsheet tool is available upon request.

    2015-01-01

    Full Text Available Requirements are critical for the success of software projects. Requirements are practically difficult to produce, as the hardest stage of building a software system is to decide what the system should do. Moreover, requirements errors are expensive to fix in the later phases of the software development life cycle. The rapidly changing business environment is highly challenging traditional Requirements Engineering (RE practices. Most of the software development organizations are working in such dynamic environment, as a result, either by or without their awareness agile methodologies are adopted in various phases of their software development cycles. The aim of this paper is to investigate the adherence degree of agile RE practices in various software development organizations that are classifying themselves as adopting traditional (i.e. non-agile software development methodologies. An approach is proposed for achieving this aim and it is applied on five different projects from four different organizations. The result shows that even the non-agile software development organizations are applying agile RE practices by different adherence degrees.

    2017-05-04

    According to the information-seeking behaviors of patients, booklets which can be downloaded from the Internet for free are an important source of information notably for patients with cancer. This study investigated whether information booklets for patients with cancer available at German websites are in accordance with the formal and content criteria of evidence-based information. We compared and compiled both content and formal criteria by matching different national and international standards for written patient information using a merged instrument. A catalog with a total of 16 items within 4 categories (quality of the publication, quality of information, quality of information representation, and transparency) was created. Patient information booklets for the most frequent tumor types were collected from the Internet. A total of 52 different patient booklets were downloaded and assessed. Overall, no booklet fulfilled all criteria. The quality of the publications was evaluated with an average value of 1.67 while the quality of the information had a mean value of 1.45, and the quality of information presentation had a similar rating (1.39). The transparency criteria were evaluated as lowest with an average of 1.07. In summary, German booklets for cancer patients have some shortcomings concerning formal and content criteria for evidence-based patient information. The applied requirement catalog is suitable for wide use and may help in quality assurance of health information. It may be used as part of an obligatory external evaluation, which could help improving the quality of health information.

    2010-12-01

    Objective  Thrombolysis decreases the chance of post-stroke dependence, although its use carries significant risk, notably of intra-cerebral haemorrhage. Patients (and families) face an important risk/benefit decision before consenting. We drafted a patient information booklet for this purpose, and applied performance-based readability testing with the aim that the most important information in the booklet could be found and understood. Methods  The booklet was developed with reference to best practice in information writing and design. We User-Tested its performance on 56 people without prior experience of stroke. After reading the booklet they were asked to find and explain 15 pieces of information. The booklet was revised according to its performance and re-tested, until each item was found and understood by at least 80% of participants. Key findings  The four-page information booklet contained approximately 900 words, organised into six sections. A risk-palette graphic showed the chance of positive and negative outcomes. The booklet was tested on four participant cohorts and revised, including more bold text, re-wording, changing the title and changing the graphic to a coloured bar chart. Testing the final version on the fourth cohort of 20 people showed that each of the 15 tested items of information met the target of at least 80% participants being able to find and understand it. Conclusions  The use of information design and User Testing produced a booklet that is understandable by people with no prior experience of stroke. User Testing is an inexpensive and quick method to ensure that information intended for patients is usable.

    The needs of grandparents of children with cancer are often overlooked. This study evaluated a new educational resource (booklet) targeted toward grandparents of children with cancer. A multidisciplinary committee developed a printed booklet targeting grandparents' information needs identified in a previous study. Seventy-nine grandparents of children with cancer (63% grandmothers, Mage = 66.04, SD = 7.0 years) read and evaluated the booklet. Quantitative responses were analyzed with SPSS, and qualitative responses were thematically coded using QSR NVivo 10. Grandparents' responses to the resource were positive, with 92% finding the booklet "informative" (n = 73), "useful" (84%, n = 66), and "very relevant" (50%, n = 39). Qualitative responses reflected an appreciation for the booklet's readability, informative content, and quotes from grandparent experiences. The developed booklet was highly acceptable to grandparents of children with cancer and addressed their need for reassurance and guidance on obtaining further support. This study demonstrates the feasibility of developing and evaluating a targeted resource to meet grandparent's identified information needs.

    Under Kenyan guidelines, HIV-exposed infants should be tested for HIV DNA at 6 weeks or at first clinical contact thereafter, as infants come for immunization. Following the introduction of early infant diagnoses programmes, however, many infants were not being tested and linked to care and treatment. We developed the Mother & Child Health Booklet to help relate mothers’ obstetrical history to infants’ healthcare providers to facilitate follow-up and timely management. The booklet contains information on the mother’s pregnancy, delivery and postpartum course and her child’s growth and development, immunization, nutrition and other data need to monitor the child to 5 years of age. It replaced three separate record clinical cards. In a 1 year pilot evaluation of the booklet in Nyanza province in 2007–08, the number of HIV DNA tests on infants increased by 34% from 9966 to 13 379. The booklet was subsequently distributed nationwide in 2009. Overall, the numbers of infants tested for HIV DNA rose from 27 000 in 2007 to 60 000 in 2012, which represents approximately 60% of the estimated HIV-exposed infants in Kenya. We believe that the booklet is an important strategy for identifying and treating infected infants and, thus, in progress toward Millennium Development Goal 4. PMID:26342124

    Early universal preventive interventions have the potential to improve the parent-infant relationship. Getting it Right from the Start is a DVD and booklet given free to new parents to promote sensitive and responsive early parenting and infant communication. Parents in the local area were canvassed for their views and opinions as to what their needs and feelings were about infant mental health. The resource is based on evidence from research and clinical studies in infant development and infant mental health. A matched sample design evaluation study was conducted. A 'Baby Quiz' testing parents' knowledge of different areas covered in the DVD and booklet was given to parents in receipt of the materials and also to parents not yet in receipt of the resource. Results indicated that the mean number of correct responses to the quiz items was higher in the group receiving the DVD and booklet. The percentage of poor scorers in the group who received the DVD and booklet was almost half that of the control group, showing the effectiveness of this universal intervention. Getting it Right from the Start represents a simple, low-cost method of reaching parents during the perinatal period.

Many patients who would benefit from statin therapy either do not adhere to or stop taking their statin medication within the first year. We developed an audio booklet targeted to low health literacy patients to teach them about the benefits and risks of statins to help the patients adhere to their statin therapy.Methods: Through focus groups and an iterative design, an audio booklet was developed for both English-speaking and Spanish-speaking patients. We then compared the booklet with standard of care in 132 patients from our target patient population to measure its impact on knowledge and understanding of statins.Results: The patients enjoyed the audio booklet and showed significant increases in knowledge after listening to it when compared with those who received the standard of care materials.Conclusion: The audio booklet shows promise as a tool that can be used effectively in clinical practice to teach patients about statin therapy.Keywords: patient adherence, patient education, medical decision-making, hypercholesterolemia

    2009-12-01

    Full Text Available Abstract Background Dizziness is a very common symptom that often leads to reduced quality of life, anxiety and emotional distress, loss of fitness, lack of confidence in balance, unsteadiness and an increased risk of falling. Most dizzy patients are managed in primary care by reassurance and medication to suppress symptoms. Trials have shown that chronic dizziness can be treated effectively in primary care using a self-help booklet to teach patients vestibular rehabilitation exercises that promote neurological adaptation and skill and confidence in balance. However, brief support from a trained nurse was provided in these trials, and this model of managing dizzy patients has not been taken up due to a lack of skills and resources in primary care. The aim of this trial is to evaluate two new alternative models of delivery that may be more feasible and cost-effective. Methods/Design In a single blind two-centre pragmatic controlled trial, we will randomise 330 patients from 30 practices to a self-help booklet with telephone support from a vestibular therapist, b self-help booklet alone, c routine medical care. Symptoms, disability, handicap and quality of life will be assessed by validated questionnaires administered by post at baseline, immediately post-treatment (3 months, and at one year follow-up. The study is powered to test our primary hypothesis, that the self-help booklet with telephone support will be more effective than routine care. We will also explore the effectiveness of the booklet without any support, and calculate the costs of treatment in each arm. Discussion If our trial indicates that patients can cost-effectively manage their dizziness in primary care, then it can be easily rolled out to relieve the symptoms of the many patients in primary care who currently have chronic, untreated, disabling dizziness. Treatment in primary care may reduce the development of psychological and physical sequelae that cause handicap and require

    E-learning can increase knowledge in patients and provide an efficient way to enhance the personnel-patient interaction as well as patient-specific education materials. So, the aim of this study was to compare the effects of two methods, multimedia and illustrated booklet educational method, on primigravida women's knowledge of prenatal care. This was a quasi-experimental study based on pre- and post-tests carried out on 100 primigravida women (50 in electronic and 50 in illustrated booklet groups) referring to Navabsafavi Health Center of Isfahan University of Medical Sciences in 2012. Subjects were randomly divided into two groups of learning interventions, including multimedia and illustrated booklet. Subjects' knowledge scores were collected using a researcher-made questionnaire with 50 questions. Before training, the mean scores (out of 50) of knowledge in e-learning and illustrated booklet education groups were 29.21 ± 7.4 and 30.01 ± 6.4, respectively. The difference between the mean scores was not significant 4-6 weeks after education. The score was 44.74 ± 3.4 in the e-learning group and 40.74 ± 6.4 in the illustrated booklet group, which showed a statistically significant difference (P learning and illustrated booklet groups as 61% and 37%, respectively. This study showed that the courses of e-learning training improved the knowledge of pregnant women to a higher extent compared to illustrated booklet education. Therefore, different aspects of e-learning, including computer literacy and infrastructure of telecommunications, should be revised.

  1. [Evaluation of methodological quality in published RCTs on cataract surgery : Pilot study on the degree of adherence to CONSORT statement requirements and their qualitative validity].

    The CONSORT statement can be considered as a guideline to ensure transparency in the reporting of randomized clinical trials (RCT), in addition to specific author instructions and requirements of journals. It provides a total of 25 criteria and 12 additional subcriteria on methodological and regulatorical determinants of clinical trials. The availability of the CONSORT recommendations, however, does not necessarily imply adherence to their obligations and correct realisation of the latter from a methodological perspective, so that even in ophthalmology a lack of transparency in trial reporting cannot be excluded. The question was whether a consistent consideration of the CONSORT checklist criteria by authors actually implied transparent reporting of underlying study results. This pilot study was based on a random sample of six published RCTs on cataract surgery extracted from an existing trial publication register. Compliance with each of the 25 CONSORT criteria and its 12 subcriteria and the content accuracy of the latter were independently assessed by two parallel raters for the six trial publications. The median compliance with the 37 CONSORT criteria and subcriteria was 62% [min-max 48-81%]; the median fraction of their correct implementation was 47% [min-max 34-69%]. Promotion of transparent reporting by means of the CONSORT statement appears to be problematic in implementation. There is a discrepancy between information as required by CONSORT and the content accuracy of its actual presentation. Thus, in particular, reviewers of clinical trial publications should not only check for the presence of data to be provided according to CONSORT, but also verify the meaningfulness in the respective context, at least on a random basis.

    Full Text Available ABSTRACT Objective: To describe the process of manufacturing and validation of an educational booklet for HIV/Aids prevention in older adults Methods: Methodological study developed in two phases - manufacturing of the booklet and validation of the educational material by judges. The manufacturing process involved a situational diagnosis with older adults, and its result indicated gaps in the knowledge with respect to HIV/Aids. The validation process was performed by nine judges, selected by convenience. It was considered an agreement index of at least 0.80, analyzed through the content validity index. Results: We opted for a dialogue between two older adults divided into three categories: myths and taboos; ignorance; and prevention and importance of diagnosis. The average of the items was 0.90. The suggestions made by the judges were observed and modified for the final version. Conclusion: The material had relevant content for the judges, in addition to being able to be used by health professionals in the education and clarification of issues on the subject.

    This study aimed to compare the effects between group discussion and educational booklet on nursing students' attitude and practice toward patient privacy in Iran. A two-group, pre-test and post-test design study was conducted in 2015. The study was conducted on 60 nursing students in Kashan, Iran who were randomly allocated into two groups to be trained on patient privacy either through group discussion or by an educational booklet. The students' attitude and practice was assessed before and after the education using a questionnaire and a checklist. Data analysis was performed through paired t-test, Wilcoxon signed ranks test, and independent samples t-tests. Before the intervention, no significant difference was found between the group designated to group discussion and that designated to the educational booklet in the mean overall score of attitude (P=0.303) and practice (P=0.493) toward patient privacy. After the intervention, the mean attitude score significantly increased in the two groups (P=0.001). Moreover, the students' practice score increased in the discussion group while it did not significantly change in the booklet group (P=0.001). Both methods were effective on the students' attitude; however, the educational booklet did not affect their practice toward patient privacy. Group discussion can effectively improve the students' attitude and practice toward patient privacy.

    To describe the process of manufacturing and validation of an educational booklet for HIV/Aids prevention in older adults. Methodological study developed in two phases - manufacturing of the booklet and validation of the educational material by judges. The manufacturing process involved a situational diagnosis with older adults, and its result indicated gaps in the knowledge with respect to HIV/Aids. The validation process was performed by nine judges, selected by convenience. It was considered an agreement index of at least 0.80, analyzed through the content validity index. We opted for a dialogue between two older adults divided into three categories: myths and taboos; ignorance; and prevention and importance of diagnosis. The average of the items was 0.90. The suggestions made by the judges were observed and modified for the final version. The material had relevant content for the judges, in addition to being able to be used by health professionals in the education and clarification of issues on the subject.

    The National Diabetes Education Program created the 4 Steps to Manage Your Diabetes for Life (4 Steps) booklet to help patients with diabetes learn the basics of self-management and care recommendations. The purpose of this study is to explore the impact of 4 Steps on participants' diabetes management knowledge and self-efficacy in the Glycemia Reduction Approaches in Diabetes: A Comparative Effectiveness Study (GRADE). A sample of 348 adults with type 2 diabetes enrolled in GRADE was included in this analysis. Participants took a pretest, were sent home with 4 Steps, then took a posttest at their next visit. The Wilcoxon signed rank test was used to detect differences in knowledge and self-efficacy between scale scores pre- and posttest. Analyses revealed increases in participants' diabetes management knowledge (p diabetes education showed a statistically significant increase in knowledge scores compared to those with previous diabetes education (p diabetes education materials may improve self-management knowledge and self-efficacy among adults with type 2 diabetes. Providers should feel confident using 4 Steps as a resource for clinical practice. ©2017 American Association of Nurse Practitioners.

    2016-01-01

    A majority of studied models for scale-free networks have degree distributions with exponents greater than $2$. Real networks, however, can demonstrate essentially more heavy-tailed degree distributions. We explore two models of scale-free equilibrium networks that have the degree distribution exponent $\\gamma = 1$, $P(q) \\sim q^{-\\gamma}$. Such "superfat-tailed" degree distributions can be identified in empirical data only if the mean degree of a network is sufficiently high. Our models exploit a rewiring mechanism. They are local in the sense that no knowledge of the network structure, apart from the immediate neighbourhood of the vertices, is required. These models generate uncorrelated networks in the infinite size limit, where they are solved explicitly. We investigate finite size effects by the use of simulations. We find that both models exhibit disassortative degree-degree correlations for finite network sizes. In addition, we observe a markedly degree-dependent clustering in the finite networks. We i...

    Materials and Methods: In this semi experimental study the effect of various educational methods on nutritional knowledge, attitude and behaviors of guidance school students in Qom city in the years 2011-12 was evaluated and compared by using of a four-part questionnaire (demographic, knowledge, attitude and behavior characteristics. Three schools were selected by cluster sampling method and from each school, 110 students were randomly grouped (330 students to control, booklet and lecture groups. Firstly, the questionnaires were completed by students as a pretest and then nutritional educational program was performed for three groups in three sessions; and three months later the same questionnaires were used again. Results: Interventions caused significant increase in the mean scores of knowledge, attitude, and behavior of two experimental groups (P0.05. The mean differencesof knowledge and attitude sections in lecture group were more statistically significant than booklet group (p<0.05. Conclusion: Both educational methods increased the level of nutritional knowledge, attitude, and behaviors of students which was more significant in lecture group. Collectively, the results of this study demonstrated positive effects of educational health programs on promotion of nutritional knowledge, attitude, and behaviors of students. Therefore it is necessary to consider educational programsin order to improve nutritional behavior.

    Full Text Available To improve health education within primary schools, the health education booklet Juma na kichocho was evaluated during a study within 5 schools using key-informant questionnaires that recorded children's knowledge and attitude (KA towards schistosomiasis before and after daily structured-use of booklets. A total of 229 schoolchildren (114 boys : 115 girls of between 11 and 15 years of age were interviewed and re-assessed after a working school week. Existing and putative booklet-induced changes in KA scores for schistosomiasis were compared directly against equivalent KA scores for malaria. In total 47.4% of children were already aware that schistosomiasis was a water-borne disease while only 10.5% knew of its exact aetiology; after booklet intervention these levels increased to 54.6 and 15.7%, respectively. The majority of children still failed, however, to realise that re-infection could take place soon after treatment. While a positive increase was observed for children's total KA questionnaire scores for both malaria and schistosomiasis after booklet intervention, these were not statistically significant. In the context of control, further educational efforts are needed to promote and guide behavioural change, especially in relation to reduction of environmental water contact.

    Full Text Available Background: Depression is one of the most common mental disorders affecting people in the world. It is also a growing concern in younger population particularly medical students. There are many pharmaceutical interventions for treatment of depression but there is paucity of data to determine the effect of educational intervention on the knowledge, attitude and help seeking behaviour regarding depression among medical students. Methods: An interventional study was carried out among randomly selected 100 medical students except interns over a period of 6 months from March August 2011 in a medical college in Delhi to assess the effect of educational booklet on knowledge and attitude about depression. Data was collected using pre-tested questionnaire and analyzed using SPSS version 16 software. Statistical significance in pre and post intervention proportions was determined using Mc Nemar test (MN and for other proportions Chi-square test. Results: The study shown that only 71% of subjects knew that depression is a disease in pre intervention phase, which rose to 88% in post intervention phase (p=0.01. Knowledge of symptoms and treatment significantly improved such as trouble falling asleep or too much sleep (p=0.03, feeling tired or decreased energy (MN=17.6, p=0.01, feeling bad about self (MN=21.8, p=0.01, speaking slowly other can notice (MN=19.1, p=0.01 and can be treated by improving awareness (MN=8.6, p=0.03, and anti-depressants do not cause much of side effects (MN=17.3, p=0.01. Most common reasons for not seeking help were thinking that there is lack of understanding by other people about the depression (63%, lack of confidentiality (49%, social stigma (30%, fear of rejection (26% and time constraints (6%. Majority of students accepted the booklet for their understanding about depression where 63% considered that it improved their knowledge to great extent. Conclusion:Educational interventional booklet should be promoted at bigger

    Full Text Available The article analyses French translations of Slovenian proper names in tourist bro chures and booklets published by the Slovenian Tourist Board and the Government of the Republic of Slovenia, Public Relations and Promotion Office. We analysed the names of living beings (the group of names was expected to be less numerous and above all geographical proper names. While we did not notice any bigger problems when translating proper names of living beings, the same can be said for one word geographical proper names. The opposite holds true for multiword geographical proper names. As we believe that tourist brochures play an important role in representing the coun try abroad, we would expect translators be given more detailed guidelines as far as trans lation of proper names is concerned. We hope that the present article brings forth the hard nuts of translating proper names in a manner to encourage the creation of such guidelines.

  19. Planning a Study for Testing the Rasch Model given Missing Values due to the use of Test-booklets.

    2015-01-01

    Though calibration of an achievement test within a psychological and educational context is very often carried out by the Rasch model, data sampling is hardly designed according to statistical foundations. However, Kubinger, Rasch, and Yanagida (2009, 2011) suggested an approach for the determination of sample size according to a given Type-I and Type-II risk and a certain effect of model contradiction when testing the Rasch model. The approach uses a three-way analysis of variance design with mixed classification. For the while, their simulation studies deal with complete data, meaning every examinee is administered with all of the items of an item pool. The simulation study now presented in this paper deals with the practical relevant case, in particular for large-scale assessments, that item presentation happens to use several test-booklets. As a consequence, there are missing values by design. Therefore, the question to be considered is, whether this approach works in this case as well. Besides the fact, that data are not normally distributed but there is a dichotomous variable (an examinee either solves an item or fails to solve it), only a single entry for each cell exists in the given three-way analysis of variance design, if at all, due to missing values. Hence, the obligatory test-statistic's distribution may not be retained, in contrast to the case of having no missing values. The result of our simulation study, despite applying only to a very special scenario, is that this approach works, indeed: Whether test-booklets were used or every examinee is administered all of the items changes nothing in respect to the actual Type-I risk or to the power of the test, given almost the same amount of information of examinees per item. However, as the results are limited to a special scenario, we currently recommend any interested researcher to simulate the appropriate one in advance by him/herself.

    The future challenges to medical and biological engineering, sometimes referred to as biomedical engineering or simply bioengineering, are many. Some of these are identifiable now and others will emerge from time to time as new technologies are introduced and harnessed. There is a fundamental issue regarding "Branding the bio/biomedical engineering degree" that requires a common understanding of what is meant by a B.S. degree in Biomedical Engineering, Bioengineering, or Biological Engineering. In this paper we address some of the issues involved in branding the Bio/Biomedical Engineering degree, with the aim of clarifying the Bio/Biomedical Engineering brand.

    Edwards Rhiannon T

    2009-09-01

    Full Text Available Abstract Background Hip and knee osteoarthritis is a common cause of pain and disability, which can be improved by exercise interventions. However, regular exercise is uncommon in this group because the low physical activity level in the general population is probably reduced even further by pain related fear of movement. The best method of encouraging increased activity in this patient group is not known. A booklet has been developed for patients with hip or knee osteoarthritis. It focuses on changing disadvantageous beliefs and encouraging increased physical activity. Methods/Design This paper describes the design of a Phase II randomised controlled trial (RCT to test the effectiveness of this new booklet for patients with hip and knee osteoarthritis in influencing illness and treatment beliefs, and to assess the feasibility of conducting a larger definitive RCT in terms of health status and exercise behaviour. A computerised search of four general medical practice patients' record databases will identify patients older than 50 years of age who have consulted with hip or knee pain in the previous twelve months. A random sample of 120 will be invited to participate in the RCT comparing the new booklet with a control booklet, and we expect 100 to return final questionnaires. This trial will assess the feasibility of recruitment and randomisation, the suitability of the control intervention and outcome measurement tools, and will provide an estimate of effect size. Outcomes will include beliefs about hip and knee pain, beliefs about exercise, fear avoidance, level of physical activity, health status and health service costs. They will be measured at baseline, one month and three months. Discussion We discuss the merits of testing effectiveness in a phase II trial, in terms of intermediate outcome measures, whilst testing the processes for a larger definitive trial. We also discuss the advantages and disadvantages of testing the psychometric

    Full Text Available Background: Nutrition as an important factor in health can be effective in educational success of students. Malnourished students have less concentration and attention. Lack of breakfast consumption for a long period has negative effect in behavior and health. The purpose of this study is to determine the effect of a nutritional teaching booklet about breakfast on the knowledge of fourth grade girls at Tehran's 6th educational and teaching district.Methods: This interventional study performed on 100 fourth grade girls from 10 schools in Tehran city, randomly divided into two groups; case who received booklet and control group. Subject: At first a pretest of knowledge was done for all the students (case and control. The case group was given the booklet to read by themselves. No teaching provided for the control group. A knowledge posttest was performed two weeks later. Two types of questionnaires (general and knowledge were used to collect data. The following methods were used: chi-square test for comparing case and control groups from the aspect of independent variables, pair t- test for comparing the knowledge scores between case and control groups and one-way ANOVA for assessment of independent variables effect on the mean difference of knowledge in samples.Results: The mean score of knowledge in the case group against the control increased 2.22 (p<0.001. The one-way ANOVA method showed that none of the independent variables (family size, parents' career and educational level, dinner breakfast sleeping and waking up time, the person who prepares breakfast at home, breakfast consumption status in other members of family had significant effect on the mean of the knowledge scores' difference. Conclusions: The results of this study showed the nutritional teaching booklet about breakfast caused an increase in the knowledge of this age group of girl students.

  20. Quantitative modeling of degree-degree correlation in complex networks

    Niño, Alfonso

    2013-01-01

    This paper presents an approach to the modeling of degree-degree correlation in complex networks. Thus, a simple function, \\Delta(k', k), describing specific degree-to- degree correlations is considered. The function is well suited to graphically depict assortative and disassortative variations within networks. To quantify degree correlation variations, the joint probability distribution between nodes with arbitrary degrees, P(k', k), is used. Introduction of the end-degree probability function as a basic variable allows using group theory to derive mathematical models for P(k', k). In this form, an expression, representing a family of seven models, is constructed with the needed normalization conditions. Applied to \\Delta(k', k), this expression predicts a nonuniform distribution of degree correlation in networks, organized in two assortative and two disassortative zones. This structure is actually observed in a set of four modeled, technological, social, and biological networks. A regression study performed...

  1. Communicating the benefits and harms of colorectal cancer screening needed for an informed choice: a systematic evaluation of leaflets and booklets.

    Maren Dreier

    Full Text Available Evidence-based health information (EBHI can support informed choice regarding whether or not to attend colorectal cancer (CRC screening. The present study aimed to assess if German leaflets and booklets appropriately inform consumers on the benefits and harms of CRC screening.A systematic search for print media on CRC screening was performed via email enquiry and internet search. The identified documents were assessed for the presence and correctness of information on benefits and harms by two reviewers independently using a comprehensive list of criteria.Many of the 28 leaflets and 13 booklets identified presented unbalanced information on the benefits and harms of CRC screening: one-third did not provide any information on harms. Numeracy information was often lacking. Ten cross-language examples of common misinterpretations or basically false and misleading information were identified.Most of the CRC screening leaflets and booklets in Germany do not meet current EBHI standards. After the study, the publishers of the information materials were provided feedback, including a discussion of our findings. The results can be used to revise existing information materials or to develop new materials that provide correct, balanced, quantified, understandable and unbiased information on CRC screening.

  3. The effect of using an interactive booklet on childhood respiratory tract infections in consultations: Study protocol for a cluster randomised controlled trial in primary care

    Directory of Open Access Journals (Sweden)

    Nuttall Jacqueline

    2008-04-01

    Full Text Available Abstract Background Respiratory tract infections in children result in more primary care consultations than any other acute condition, and are the most common reason for prescribing antibiotics (which are largely unnecessary. About a fifth of children consult again for the same illness episode. Providing parents with written information on respiratory tract infections may result in a reduction in re-consultation rates and antibiotic prescribing for these illnesses. Asking clinicians to provide and discuss the information during the consultation may enhance effectiveness. This paper outlines the protocol for a study designed to evaluate the use of a booklet on respiratory tract infections in children within primary care consultations. Methods/Design This will be a cluster randomised controlled trial. General practices will be randomised to provide parents consulting because their child has an acute respiratory tract infection with either an interactive booklet, or usual care. The booklet provides information on the expected duration of their child's illness, the likely benefits of various treatment options, signs and symptoms that should prompt re-consultation, and symptomatic treatment advice. It has been designed for use within the consultation and aims to enhance communication through the use of specific prompts. Clinicians randomised to using the interactive booklet will receive online training in its use. Outcomes will be assessed via a telephone interview with the parent two weeks after first consulting. The primary outcome will be the proportion of children who re-consult for the same illness episode. Secondary outcomes include: antibiotic use, parental satisfaction and enablement, and illness costs. Consultation rates for respiratory tract infections for the subsequent year will be assessed by a review of practice notes. Discussion Previous studies in adults and children have shown that educational interventions can result in reductions

    2015-04-01

    We investigated the internal structure comparability of Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) scores derived from the MMPI-2 and MMPI-2-RF booklets in a sample of 320 criminal defendants (229 males and 54 females). After exclusion of invalid protocols, the final sample consisted of 96 defendants who were administered the MMPI-2-RF booklet and 83 who completed the MMPI-2. No statistically significant differences in MMPI-2-RF invalidity rates were observed between the two forms. Individuals in the final sample who completed the MMPI-2-RF did not statistically differ on demographics or referral question from those who were administered the MMPI-2 booklet. Independent t tests showed no statistically significant differences between MMPI-2-RF scores generated with the MMPI-2 and MMPI-2-RF booklets on the test's substantive scales. Statistically significant small differences were observed on the revised Variable Response Inconsistency (VRIN-r) and True Response Inconsistency (TRIN-r) scales. Cronbach's alpha and standard errors of measurement were approximately equal between the booklets for all MMPI-2-RF scales. Finally, MMPI-2-RF intercorrelations produced from the two forms yielded mostly small and a few medium differences, indicating that discriminant validity and test structure are maintained. Overall, our findings reflect the internal structure comparability of MMPI-2-RF scale scores generated from MMPI-2 and MMPI-2-RF booklets. Implications of these results and limitations of these findings are discussed. © The Author(s) 2014.

  9. HEALTH EDUCATION AND THE CONTROL OF UROGENITAL SCHISTOSOMIASIS: ASSESSING THE IMPACT OF THE JUMA NA KICHOCHO COMIC-STRIP MEDICAL BOOKLET IN ZANZIBAR.

    2016-09-01

    Endeavours to control urogenital schistosomiasis on Unguja Island (Zanzibar) have focused on school-aged children. To assess the impact of an associated health education campaign, the supervised use of the comic-strip medical booklet Juma na Kichocho by Class V pupils attending eighteen primary schools was investigated. A validated knowledge and attitudes questionnaire was completed at baseline and repeated one year later following the regular use of the booklet during the calendar year. A scoring system (ranging from 0.0 to 5.0) measured children's understandings of schistosomiasis and malaria, with the latter being a neutral comparator against specific changes for schistosomiasis. In 2006, the average score from 751 children (328 boys and 423 girls) was 2.39 for schistosomiasis and 3.03 for malaria. One year later, the score was 2.43 for schistosomiasis and 2.70 for malaria from 779 children (351 boys and 428 girls). As might be expected, knowledge and attitudes scores for schistosomiasis increased (+0.05), but not as much as originally hoped, while the score for malaria decreased (-0.33). According to a Kolmogorov-Smirnov test, neither change was statistically significant. Analysis also revealed that 75% of school children misunderstood the importance of reinfection after treatment with praziquantel. These results are disappointing. They demonstrate that it is mistaken to assume that knowledge conveyed in child-friendly booklets will necessarily be interpreted, and acted upon, in the way intended. If long-term sustained behavioural change is to be achieved, health education materials need to engage more closely with local understandings and responses to urogenital schistosomiasis. This, in turn, needs to be part of the development of a more holistic, biosocial approach to the control of schistosomiasis.

  10. Node degree distribution in spanning trees

    Pozrikidis, C.

    2016-03-01

    A method is presented for computing the number of spanning trees involving one link or a specified group of links, and excluding another link or a specified group of links, in a network described by a simple graph in terms of derivatives of the spanning-tree generating function defined with respect to the eigenvalues of the Kirchhoff (weighted Laplacian) matrix. The method is applied to deduce the node degree distribution in a complete or randomized set of spanning trees of an arbitrary network. An important feature of the proposed method is that the explicit construction of spanning trees is not required. It is shown that the node degree distribution in the spanning trees of the complete network is described by the binomial distribution. Numerical results are presented for the node degree distribution in square, triangular, and honeycomb lattices.

    Full Text Available The maps of the form f( x = ∑ i=1 n a i ⋅x⋅ b i , called 1-degree maps, are introduced and investigated. For noncommutative algebras and modules over them 1-degree maps give an analogy of linear maps and differentials. Under some conditions on the algebra 𝒜 , contractibility of the group of 1-degree isomorphisms is proved for the module l 2 ( 𝒜 . It is shown that these conditions are fulfilled for the algebra of linear maps of a finite-dimensional linear space. The notion of 1-degree map gives a possibility to define a nonlinear Fredholm map of l 2 ( 𝒜 and a Fredholm manifold modelled by l 2 ( 𝒜 . 1-degree maps are also applied to some problems of Markov chains.

    Frequently, it is argued that the microstates responsible for the Bekenstein-Hawking entropy should arise from some physical degrees of freedom located near or on the black hole horizon. In this essay, we elucidate that instead entropy may emerge from the conversion of physical degrees of freedom, attached to a generic boundary, into unobservable gauge degrees of freedom attached to the horizon. By constructing the reduced phase space, it can be demonstrated that such a transmutation indeed takes place for a large class of black holes, including Schwarzschild.

    We propose a generalization of the concept of assortativity based on the tensorial representation of multilayer networks, covering the definitions given in terms of Pearson and Spearman coefficients. Our approach can also be applied to weighted networks and provides information about correlations considering pairs of layers. By analyzing the multilayer representation of the airport transportation network, we show that contrasting results are obtained when the layers are analyzed independently or as an interconnected system. Finally, we study the impact of the level of assortativity and heterogeneity between layers on the spreading of diseases. Our results highlight the need of studying degree-degree correlations on multilayer systems, instead of on aggregated networks.

  1. Exact sampling of graphs with prescribed degree correlations

    Bassler, Kevin E; Erdős, Péter L; Miklós, István; Toroczkai, Zoltán

    2015-01-01

    Many real-world networks exhibit correlations between the node degrees. For instance, in social networks nodes tend to connect to nodes of similar degree. Conversely, in biological and technological networks, high-degree nodes tend to be linked with low-degree nodes. Degree correlations also affect the dynamics of processes supported by a network structure, such as the spread of opinions or epidemics. The proper modelling of these systems, i.e., without uncontrolled biases, requires the sampling of networks with a specified set of constraints. We present a solution to the sampling problem when the constraints imposed are the degree correlations. In particular, we develop an efficient and exact method to construct and sample graphs with a specified joint-degree matrix, which is a matrix providing the number of edges between all the sets of nodes of a given degree, for all degrees, thus completely specifying all pairwise degree correlations, and additionally, the degree sequence itself. Our algorithm always pro...

    This small, non-contact optical sensor increases the capability and flexibility of computer controlled machines by detecting its relative position to a workpiece in all six degrees of freedom (DOF). At a fraction of the cost, it is over 200 times faster and up to 25 times more accurate than competing 3-DOF sensors. Applications range from flexible manufacturing to a 6-DOF mouse for computers. Until now, highly agile and accurate machines have been limited by their inability to adjust to changes in their tasks. By enabling them to sense all six degrees of position, these machines can now adapt to new and complicated tasks without human intervention or delay--simplifying production, reducing costs, and enhancing the value and capability of flexible manufacturing.

    Full Text Available Purpose — the purpose of this article is to extend discussion towards the need and importance of joint degree programs in modern universities, introducing the perspective of the employers toward this question. Design/methodology/approach — the research was conducted to analyze the demand of joint degree programs from the perspective of employers, identify weak and strong aspects, opinion and demand for graduates of such programs. To achieve this purpose, a combination of theoretical and empirical methods was chosen: document analysis (previous studies, statistics was conducted and an online qualitative survey was organized. Findings — The analysis of articles, studies and statistics points out the challenges and threats faced by universities nowadays, forcing higher education institutions to find new ways to raise the quality of studies and raise the interest of employers to choose graduates from MRU, as well as the satisfaction of employers with their choice of employees. Theoretical analysis pointed out these challenges and requirements for the modern employee, summarised the challenges in preparation of IT field specialists. The conducted research results showed that the diploma of joint degree programs would not be treated as an advantage of possible employee from the perspective of employers in case some important aspects will not be taken into consideration by program creators. On the other hand, undeniably there are strong sides, such as knowledge in the fields of foreign language, international experience, innovativeness and creativeness of employees that would be treated as an advantage in the process of selection for positions of any technical support related positions. Research limitations/implications — employers, whose business activities are closely related to information technology, have been invited as experts. In addition, these experts have a good understanding of the specifics of joint degree programs. The received

    Fever is the most common reason for a child to be taken to a general practitioner (GP), especially during out-of-hours care. It is mostly caused by self-limiting infections. However, antibiotic prescription rates remain high, especially during out-of-hours care. Anxiety and lack of knowledge among parents, and perceived pressure to prescribe antibiotics amongst GPs, are important determinants of excessive antibiotic prescriptions. An illness-focused interactive booklet has the potential to improve this by providing parents with information about fever self-management strategies. The aim of this study is to develop and determine the effectiveness of an interactive booklet on management of children presenting with fever at Dutch GP out-of-hours cooperatives. We are conducting a cluster randomised controlled trial (RCT) with 20 GP out-of-hours cooperatives randomised to 1 of 2 arms: GP access to the illness-focused interactive booklet or care as usual. GPs working at intervention sites will have access to the booklet, which was developed in a multistage process. It consists of a traffic light system for parents on how to respond to fever-related symptoms, as well as information on natural course of infections, benefits and harms of (antibiotic) medications, self-management strategies and 'safety net' instructions. Children parent-reported or physician-measured fever are eligible for inclusion. The primary outcome is antibiotic prescribing during the initial consultation. Secondary outcomes are (intention to) (re)consult, antibiotic prescriptions during re-consultations, referrals, parental satisfaction and reassurance. In 6 months, 20,000 children will be recruited to find a difference in antibiotic prescribing rates of 25% in the control group and 19% in the intervention group. Statistical analysis will be performed using descriptive statistics and by fitting two-level (GP out-of-hours cooperative and patient) random intercept logistic regression models. This will

    The arithmetic degree, the smallest extended degree, and the homological degree are invariants that have been proposed as alternatives of the degree of a module if this module is not Cohen-Macaulay. We compare these degree functions and study their behavior when passing to the generic initial or the lexicographic submodule. This leads to various bounds and to counterexamples to a conjecture of Gunston and Vasconcelos, respectively. Particular attention is given to the class of sequentially Co...

    Animal telemetry, which requires the implantation of passive transponders or active transmitters, is used to monitor and assess fish stock and conservation to gain an understanding of fish movement and behavior. As new telemetry technologies become available, studies of their effects on species of interest are imperative as is development of implantation techniques. In this study, we investigated the effects of bevel rotation (0-, 90-, 180-degree axis rotation) on wound extent, tag loss, and wound healing rates in juvenile Chinook salmon injected with an 8-gauge needle, which is required for implantation of the novel injectable Juvenile Salmon Acoustic Telemetry Systems (JSATS) acoustic transmitter or large passive integrated transponder (PIT) tags. Although the injection sites were not closed after injection (e.g., with sutures or glue), there were no mortalities, dropped tags, or indications of fungus, ulceration, and/or redness around the wound. On Day 0 and post-implantation Day 7, the 90-degree bevel rotation produced smaller wound extent than the 180-degree bevel rotation. No axis rotation (0-degrees) resulted in the PIT tag frequently misleading or falling out upon injection. The results of this study indicated the 90-degree bevel rotation was the more efficient technique, produced less wound extent. Given the wound extent compared to size of fish, we recommend researchers should consider a 90-degree rotation over the 180-degree rotation in telemetry studies. Highlights •Three degrees of needle rotation were examined for effects in Chinook salmon. •Mortality, tag loss, wound extent, healing, and infection indicators were measured. •There were no mortalities, tag loss, or indications of infection. •The 90-degree needle rotation through Day 7 produced the smallest wound extent.

    2007-01-01

    Complex networks have been applied to model numerous interactive nonlinear systems in the real world. Knowledge about network topology is crucial to an understanding of the function, performance and evolution of complex systems. In the last few years, many network metrics and models have been proposed to investigate the network topology, dynamics and evolution. Since these network metrics and models are derived from a wide range of studies, a systematic study is required to investigate the correlations among them. The present paper explores the effect of degree correlation on the other network metrics through studying an ensemble of graphs where the degree sequence (set of degrees) is fixed.We show that to some extent, the characteristic path length, clustering coefficient, modular extent and robustness of networks are directly influenced by the degree correlation.

    1988-12-10

    Intelligence test scores and educational levels were compared for 5943 myopic and 9891 non-myopic 18-year-old men being drafted for military service in Denmark. The former were grouped by degree of myopia, in the range -0.25 diopters (D) to -7.75 D, according to the power of correcting lenses required. Myopes of all degrees had significantly higher test scores and educational levels than non-myopes. However, the relation of these two variables to degree of myopia was not linear; for both variables there were no significant differences among myopia groups in the range -2.0 to -7.75 D. Whereas factors associated with intelligence and education seem to be important in triggering the onset of myopia, they seem to be much less important in determining the degree to which myopia progresses.

    A statewide study was done with five associate degree (ADN) and five baccalaureate degree (BSN) nursing programs in Georgia to examine the similarities and differences in curriculum based on a nationally used model. From this overall study, select content related to community/home health care was evaluated in the sample programs. Professional standards for community and home health care nursing practice, as well as other published literature on the topic, provided a basis to determine competence to practice. Data were collected through a taped telephone interview to all program chairpersons (N = 10) and mailed questionnaires to faculty involved with all required courses (N = 110). Content analyses of responses allowed for evaluation of frequency of these learning activities between ADN and BSN programs and among BSN programs in the areas of family, teaching, interdisciplinary collaboration, physical assessment, and leadership. Overall, the results indicated lack of conclusive data to support a distinct difference in these educational components between the ADN and BSN sample or among BSN programs. The study was intended to service as a basis for home health care curriculum development in the future.

  7. Assessing Degree of Susceptibility to Landslide Hazard

    Sheridan, M. F.; Cordoba, G. A.; Delgado, H.; Stefanescu, R.

    2013-05-01

    The modeling of hazardous mass flows, both dry and water saturated, is currently an area of active research and several stable models have now emerged that have differing degrees of physical and mathematical fidelity. Models based on the early work of Savage and Hutter (1989) assume that very large dense granular flows could be modeled as incompressible continua governed by a Coulomb failure criterion. Based on this concept, Patra et al. (2005) developed a code for dry avalanches, which proposes a thin layer mathematical model similar to shallow-water equations. This concept was implemented in the widely-used TITAN2D program, which integrates the shock-capturing Godunov solution methodology for the equation system. We propose a method to assess the susceptibility of specific locations susceptible to landslides following heavy tephra fall using the TIATN2D code. Successful application requires that the range of several uncertainties must be framed in the selection of model input data: 1) initial conditions, like volume and location of origin of the landslide, 2) bed and internal friction parameters and 3) digital elevation model (DEM) uncertainties. Among the possible ways of coping with these uncertainties, we chose to use Latin Hypercube Sampling (LHS). This statistical technique reduces a computationally intractable problem to such an extent that is it possible to apply it, even with current personal computers. LHS requires that there is only one sample in each row and each column of the sampling matrix, where each row (multi-dimensional) corresponds to each uncertainty. LHS requires less than 10% of the sample runs needed by Monte Carlo approaches to achieve a stable solution. In our application LHS output provides model sampling for 4 input parameters: initial random volumes, UTM location (x and y), and bed friction. We developed a simple Octave script to link the output of LHS with TITAN2D. In this way, TITAN2D can run several times with successively different

  8. Degree-layer theory of network topology

    CERN Document Server

    Zhou, Bin; Zhe, He

    2014-01-01

    The network topology can be described by the number of nodes and the interconnections among them. The degree of a node in a network is the number of connections it has to other nodes and the degree distribution is the probability distribution of these degrees over the whole network. Therefore, the degree is very important structural parameter of network topology. However, given the number of nodes and the degree of each node in a network, the topology of the network cannot be determined. Therefore, we propose the degree-layer theory of network topology to describe deeply the network topology. First, we propose the concept of degree-tree with the breadth-first search tree. The degrees of all nodes are layered and have a hierarchical structure. Second,the degree-layer theory is described in detail. Two new concepts are defined in the theory. An index is proposed to quantitatively distinguish the two network topologies. It also can quantitatively measure the stability of network topology built by a model mechani...

  9. Cooperation in an evolutionary prisoner's dilemma on networks with degree-degree correlations.

    Devlin, Stephen; Treloar, Thomas

    2009-08-01

    We study the effects of degree-degree correlations on the success of cooperation in an evolutionary prisoner's dilemma played on a random network. When degree-degree correlations are not present, the standardized variance of the network's degree distribution has been shown to be an accurate analytical measure of network heterogeneity that can be used to predict the success of cooperation. In this paper, we use a local-mechanism interpretation of standardized variance to give a generalization to graphs with degree-degree correlations. Two distinct mechanisms are shown to influence cooperation levels on these types of networks. The first is an intrinsic measurement of base-line heterogeneity coming from the network's degree distribution. The second is the increase in heterogeneity coming from the degree-degree correlations present in the network. A strong linear relationship is found between these two parameters and the average cooperation level in an evolutionary prisoner's dilemma on a network.

  10. Complexity of Splits Reconstruction for Low-Degree Trees

    CERN Document Server

    Gaspers, Serge; Stein, Maya; Suchan, Karol

    2010-01-01

    Given a vertex-weighted tree T, the split of an edge xy in T is min(s_x, s_y) where s_x (respectively, s_y) is the sum of all weights of vertices that are closer to x than to y (respectively, closer to y than to x) in T. Given a set of weighted vertices V and a multiset of splits S, we consider the problem of constructing a tree on V whose splits correspond to S. The problem is known to be NP-complete even when all vertices have unit weight and the maximum vertex degree of T is required to be no more than 4. We show that the problem is even strongly NP-complete when T is required to be a path. For this variant we also exhibit an algorithm that runs in polynomial time when the number of distinct vertex weights is constant. We also show that the problem is NP-complete when all vertices have unit weights and the maximum degree of T is required to be no more than 3, and even NP-complete when all vertices have unit weight and T is required to be a caterpillar with unbounded hair length and maximum degree at most 3...

  11. Precision Magnetic Bearing Six Degree of Freedom Stage

    Science.gov (United States)

    Williams, M. E.; Trumper, David L.

    1996-01-01

    Magnetic bearings are capable of applying force and torque to a suspended object without rigidly constraining any degrees of freedom. Additionally, the resolution of magnetic bearings is limited only by sensors and control, and not by the finish of a bearing surface. For these reasons, magnetic bearings appear to be ideal for precision wafer positioning in lithography systems. To demonstrate this capability a linear magnetic bearing has been constructed which uses variable reluctance actuators to control the motion of a 14.5 kg suspended platen in five degrees of freedom. A Lorentz type linear motor of our own design and construction is used to provide motion and position control in the sixth degree of freedom. The stage performance results verify that the positioning requirements of photolithography can be met with a system of this type. This paper describes the design, control, and performance of the linear magnetic bearing.

  19. Infinite-degree-corrected stochastic block model

    DEFF Research Database (Denmark)

    Herlau, Tue; Schmidt, Mikkel Nørgaard; Mørup, Morten

    2014-01-01

    In stochastic block models, which are among the most prominent statistical models for cluster analysis of complex networks, clusters are defined as groups of nodes with statistically similar link probabilities within and between groups. A recent extension by Karrer and Newman [Karrer and Newman......, Phys. Rev. E 83, 016107 (2011)] incorporates a node degree correction to model degree heterogeneity within each group. 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. Additionally, our formulation yields principled ways of inferring the number of groups as well as predicting missing links...

    2012-01-01

    Given a vertex v of a graph G the second order degree of v denoted as d2 (v) is defined as the number of vertices at distance 2 from v.In this paper we address the following question:What are the sufficient conditions for a graph to have a vertex v such that d2(v) ≥ d(v),where d(v) denotes the degree of v? Among other results,every graph of minimum degree exactly 2,except four graphs,is shown to have a vertex of second order degree as large as its own degree.Moreover,every K-4-free graph or every maximal planar graph is shown to have a vertex v such that d2(v) ≥ d(v).Other sufficient conditions on graphs for guaranteeing this property are also proved.

    2011-01-01

    For a finitely generated algebra over a field, the transcendence degree is known to be equal to the Krull dimension. The aim of this paper is to generalize this result to algebras over rings. A new definition of the transcendence degree of an algebra A over a ring R is given by calling elements of A algebraically dependent if they satisfy an algebraic equation over R whose trailing coefficient, with respect to some monomial ordering, is 1. The main result is that for a finitely generated algebra over a Noetherian Jacobson ring, the transcendence degree is equal to the Krull dimension.

  5. Degrees of Curves in Abelian Varieties

    CERN Document Server

    Debarre, O

    1992-01-01

    The degree of a curve $C$ in a polarized abelian variety $(X,\\lambda)$ is the integer $d=C\\cdot\\lambda$. When $C$ generates $X$, we find a lower bound on $d$ which depends on $n$ and the degree of the polarization $\\lambda$. The smallest possible degree is $d=n$ and is obtained only for a smooth curve in its Jacobian with its principal polarization (Ran, Collino). The cases $d=n+1$ and $d=n+2$ are studied. Moreover, when $X$ is simple, it is shown, using results of Smyth on the trace of totally positive algebraic integers, that if $d\\le 1.7719\\, n$, then $C$ is smooth and $X$ is isomorphic to its Jacobian. We also get an upper bound on the geometric genus of $C$ in terms of its degree.

  10. Interplay of degree correlations and cluster synchronization

    Science.gov (United States)

    Jalan, Sarika; Kumar, Anil; Zaikin, Alexey; Kurths, Jürgen

    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.

    At RI Beam Factory (RIBF) [1] at RIKEN Nishina Center, a variety of fast rare isotope (RI) beams are produced using the BigRIPS in-flight separator [2] for studies of exotic nuclei. The beam line following BigRIPS is designed to work as a forward spectrometer named ZeroDegree, so that it can be used for reaction studies with RI beams. The ZeroDegree spectrometer consists of two dipoles and six superconducting quadrupole triplets, of which designs are essentially the same as those of BigRIPS. It analyzes and indentifies projectile reaction residues, often in coincidence with gamma rays, and can be operated in different optics modes, depending on experimental requirements. The ZeroDegree spectrometer has recently been commissioned and used for a series of full-dress RI-beam experiments. Overview and status of the ZeroDegree spectrometer will be reported.[4pt] [1] Y.

    Full Text Available Researchers have studied the effects of anxiety on foreign language learning since the 1970's, and despite significant advances in approaches to language teaching, the literature continues to report the existence of language apprehension in the classroom and its debilitating effect on the learning process. However, very few studies have been developed in a socio-cultural context comparable to ours, namely, a Spanish university in which English is learnt. This study set out to examine and compare the feelings of anxiety experienced by university students enrolled in six different degree programs. A total of 200 students participated in this study. The data were collected using the Foreign Language Classroom Anxiety Scale (FLCAS (Horwitz, Horwitz and Cope, 1986. The analyses reveal, firstly, that all the students suffered from average anxiety levels; secondly, that only in one of the aspects is the anxiety level of participants with English as a main subject (i.e. chosen lower than that of participants for whom English is a non-elective degree requirement; and in the third place, that the relationship between anxiety and the mark obtained by participants is stronger in the case of those who have English as a degree requirement. The implications of these results for a better understanding of anxiety and foreign language learning are discussed.

    Different people choose undergraduate degrees to study at university for different reasons. To date, there have been limited attempts to identify individual differences in motivation that drive undergraduate degree choice. We identified that people choose university degrees for four reasons: career concerns (Career), intrinsic interest in the subject (Interest), an opportunity to help others (Helping) and because they are looking for an easy option to get into higher education (Loafing). We investigated whether these motivations apply to the choice of undergraduate degree in two samples: (1) undergraduate (N = 989) and (2) prospective (N = 896) students. We developed the Motivations Influencing Course Choice (MICC) questionnaire to measure these motivations. Scales of Helping, Career, Loafing, and Interest showed good psychometric properties, showed validity with respect to general life goals and personality traits, and predicted actual and prospective degree choices. We demonstrated that medical degrees were chosen due to a mixture of Helping and Career, while engineering degrees were associated with Career and low Interest in the degree. The choice of arts and humanities degrees was driven by Interest and low concern about future career, accompanied with high Loafing. We also demonstrated gender differences: females were high in Helping (both samples) and Interest (only in the undergraduate sample) motivation, while males scored higher in Career (only in the undergraduate sample) and Loafing (both samples). The findings can feed into both theoretical accounts of proximal motivation as well as provide help to improve degree programmes at universities and support better career advice. PMID:25431561

    2011-01-01

    The authors measured the neutron energy spectra of a quasi-monoenergetic (7)Li(p,n) neutron source with 246 and 389 MeV protons set at seven angles (0 degrees, 2.5 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees and 30 degrees), using a time-of-flight (TOF) method employing organic scintillators NE213 at the Research Center for Nuclear Physics (RCNP) of Osaka University. The energy spectra of the source neutrons were precisely deduced down to 2 MeV at 0 degrees and 10 MeV at other angles. The cross-sections of the peak neutron production reaction at 0 degrees were on the 35-40 mb line of other experimental data, and the peak neutron angular distribution agreed well with the Taddeucci formula. Neutron energy spectra below 100 MeV at all angles were comparable, but the shapes of the continuum above 150 MeV changed considerably with the angle. In order to consider the correction required to derive the response in the peak region from the measured total response for high-energy neutron monitors such as DAR...

    Zhong, Changchun; Robicheaux, F.

    2016-11-01

    The mechanism of decoherence for a mesoscopic quantum system with rotational degrees of freedom is studied. From a simple model of elastic scattering, we show that the nondiagonal density-matrix elements of the system exponentially decay. The decay rate depends on the difference of scattering amplitudes for different rotational configurations, leading to the gradual loss of quantum coherence between the pointer states in the orientational space. For a dielectric ellipsoid immersed in a photon-gas environment (assuming no absorption), the decay rate is found to be proportional to the seventh power of the temperature. For an ellipsoidal object interacting with massive particles, the decay rate is proportional to the 5/2 power of the temperature. Both are different from the case of translational decoherence induced by the same environment scattering. For photon scattering, the coherence time in the rotational degrees of freedom is shown to be much shorter than that in the translational degrees of freedom.

    Full Text Available This study aims to examine the relationship between a responsive and aproactive market orientation and the degree of novelty. Data obtainedvia an Internet survey were analysed using structural equation modelling.An analysis of 325 Slovenian firms reveals that only a proactivemarket orientation is positively related to the degree of novelty. Whilethere is no evidence of statistically significant differences in the examinedrelationships given the firm size and environmental characteristics,separate analyses in each group indicate that a proactive market orientationmay be more important for small firms and firms operatingamidst a higher level of technological turbulence. This study suggeststhat a distinction between a responsive and a proactive market orientationis important for a better understanding of the effect of a marketorientation on the degree of novelty.

    This project aims to investigate the feasibility of a 360 degree feedback systems for KINS and to design guiding rules and structures in implementing that systems. Literature survey, environmental analysis and questionnaire survey were made to ensure that 360 degree feedback is the right tool to improve performance in KINS. That review leads to conclusion that more readiness and careful feasibility review are needed before implementation of 360 degree feedback in KINS. Further the project suggests some guiding rules that can be helpful for successful implementation of that system in KINS. Those include : start with development, experiment with one department, tie it to a clear organization's goal, train everyone involve, make sure to try that system in an atmosphere of trust.

    The authors present a result for linearizing a nonlinear MIMO system by employing partial feedback - feedback at all but one input-output channel such that the SISO feedback linearization problem is solvable at the remaining input-output channel. The partial feedback effectively enhances the relative degree at the open input-output channel provided the feedback functions are chosen to satisfy relative degree requirements. The method is useful for nonlinear systems that are not feedback linearizable in a MIMO sense. Several examples are presented to show how these feedback functions can be computed. This strategy can be combined with decentralized observers for a completely decentralized feedback linearization result for at least one input-output channel.

  3. Degree of molecular self-sorting in multicomponent systems.

    Saha, Manik Lal; Schmittel, Michael

    2012-06-28

    Self-sorting represents the spontaneous and high fidelity self and/or non-self-recognition of two or more related components within a complex mixture. While the effective management of self-sorting principles perceptibly requires some key expertise in molecular programming, at a higher stage of operation it is of supreme interest to guide the process to increasingly higher degrees of self-sorting. In this article, we present the emerging principles of how to guide several components toward formation of self-sorted multicomponent architectures. To provide further guidance in denominating such systems, we suggest to utilise a systematic classification as well as a formula to evaluate their degree of self-sorting (M).

  4. 4d SCFTs from negative-degree line bundles

    Nardoni, Emily

    2016-01-01

    We construct 4d $\\mathcal{N}=1$ quantum field theories by compactifying the (2,0) theories on a Riemann surface with genus $g$ and $n$ punctures, where the normal bundle decomposes into a sum of two line bundles with possibly negative degrees $p$ and $q$. Until recently, the only available field-theoretic constructions required the line bundle degrees to be nonnegative, although supergravity solutions were constructed in the literature for the zero-puncture case for all $p$ and $q$. Here, we provide field-theoretic constructions and computations of the central charges of 4d $\\mathcal{N}=1$ SCFTs that are the IR limit of M5-branes wrapping a surface with general $p$ or $q$ negative, for general genus $g$ and number of maximal punctures $n$.

    The shape of Mercury, particularly when combined with its geoid, provides clues to the planet's internal structure, thermal evolution, and rotational history. Twenty-five million elevation measurements of the northern hemisphere, acquired by the Mercury Laser Altimeter on the MErcury Surface, Space ENvironment, GEochemistry, and Ranging spacecraft, were combined with 378 occultation measurements of radio-frequency signals from the spacecraft in the planet's southern hemisphere to reveal the low-degree shape of Mercury. We solved for the spherical-harmonic coefficients through degree and order 128 and found that Mercury's mean radius is 2439.36±0.02 km. The offset between the planet's centers of mass and figure is negligible (40±40 m) along the polar axis and modest (140±50 m) in the equatorial plane. Mercury's spherical-harmonic shape spectrum is dominated by degree 2, and the planet's first-order shape is that of a triaxial ellipsoid with semimajor axes a, b, and c. The polar radius, c, is 1.65 km less than (a+b)/2, and the equatorial difference, a-b, is 1.25 km. The long axis is rotated 15° west of Mercury's dynamically defined principal axis. Mercury's geoid is similarly dominated by degree 2 and well described by a triaxial ellipsoid. The degree-2 geoid and shape are highly correlated, but the power spectral density of the geoid at degree 2 is only 1% of its shape counterpart, implying substantial compensation of elevation variations on a global scale and that Mercury is not in hydrostatic equilibrium.

  6. 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

  9. A network with tunable clustering, degree correlation and degree distribution, and an epidemic thereon

    CERN Document Server

    Ball, Frank; Sirl, David

    2012-01-01

    A random network model which allows for tunable, quite general forms of clustering, degree correlation and degree distribution is defined. The model is an extension of the configuration model, in which stubs (half-edges) are paired to form a network. Clustering is obtained by forming small completely connected subgroups, and positive (negative) degree correlation is obtained by connecting a fraction of the stubs with stubs of similar (dissimilar) degree. An SIR (Susceptible -> Infective -> Recovered) epidemic model is defined on this network. Asymptotic properties of both the network and the epidemic, as the population size tends to infinity, are derived: the degree distribution, degree correlation and clustering coefficient, as well as a reproduction number $R_*$, the probability of a major outbreak and the relative size of such an outbreak. The theory is illustrated by Monte Carlo simulations and numerical examples. The main findings are that clustering tends to decrease the spread of disease, the effect of...

    The problem of using 360 degrees or 180 degrees data sampling techniques in transaxial SPECT imaging is still to be solved. A theoretical point source study for an ideal response detector has shown, for objects which are close enough to the origin of the reconstructed area, that there are significant differences between sections obtained by different sampling methods. A computer simulation study of line sources in a homogeneous attenuated medium has confirmed the results of clinical studies in which significant image distortion has been observed in 180 degrees sections but not in 360 degrees reconstructed images.

    After years of discussion, debate, and study, the respiratory care curriculum has evolved to a minimum of an associate degree for entry into practice. Although programs are at liberty to offer the entry-level or advanced level associate degree, most are at the advanced level. The most popular site for sponsorship of the associate degree in respiratory care is the community college. The basis for community college sponsorship seems to be its comprehensive curriculum, which focuses on a strong academic foundation in writing, communication, and the basic sciences as well as supporting a career-directed focus in respiratory care. Issues facing the community college are tied to literacy, outcomes, assessment, placement,cooperation with the community, partnerships with industry, and articulation arrangements with granting institutions granting baccalaureate degrees. Community colleges must produce a literate graduate capable of thriving in an information-saturated society. Assessment and placement will intensify as the laissez-faire attitudes toward attendance and allowing students to select courses without any accountability and evaluation of outcome become less acceptable. Students will be required to demonstrate steady progress toward established outcomes. Maintaining relations and cooperation with the local community and the health care industry will continue to be a prominent role for the community college. The challenge facing associate degree education in respiratory care at the community college level is the ability to continue to meet the needs of an expanding professional scope of practice and to provide a strong liberal arts or general education core curriculum. The needs for a more demanding and expanding respiratory care curriculum and for a rich general education core curriculum have led to increased interest in baccalaureate and graduate degree education. The value of associate degree education at the community college level is well established. It is

    Full Text Available This study identifies the status of postgraduate students at the master degree level regarding their degree completion in the three public sector universities at Jamshoro Education City. The status is identified by analyzing enrolment of the postgraduate and comparing it with rate of their degree completion. In addition, the paper also discusses their characteristics which lead them towards the degree completion. For this paper, enrolment of the postgraduate students at the master level is compared with the degree completion rate of 2008 academic session only. The result shows the obvious difference between enrolment and rate of the degree completion. In total 417 postgraduate students were enrolled in 2008 session, however, only 60 (14% of students have completed their postgraduate degrees. Those who have completed their degrees, with respect to universities 6% students belong to US (University of Sindh, 22% belong to MUET (Mehran University of Engineering & Technology and 8% students belong to LUMHS (Liaquat University of Medical & Health Sciences. The demographical data of the postgraduate students has also shown some variations like gender, age, employment, and financial resources. In addition, the research requirements also vary for different postgraduate students. The research requirements include lab based, field based and library based resources. The characteristics of the postgraduate students of three public sector universities including financial resources, employment status, and working organization also show differences with each-other in terms of the degree completion.

    Full Text Available Objective:To evaluate a method to reduce high degree spondylolisthesis in adults with monosegmental fixing preserving the adjacent level and the improvement of sagittal balance.Methods:A prospective study, with 12 adult patients with high degree spondylolisthesis (III and IV in adults who underwent surgery by the same team. We included 7 women and 5 men with a mean age of 37 years and lombosciatalgy that had no improvement with conservative treatment. The surgical technique used was total or partial reduction by Spondylolisthesis Reduction Instrument (SRI system, with instrumentation only in the affected level, thus sparing the adjacent level, associated with 360ofusion.Results:The L5-S1 level was involved in nine patients, L4-L5 in two, and VT-S1 in one patient. The isthmic type predominated in nine patients, followed by dysplastic type in two, and one iatrogenic spondylolisthesis. These patients were assessed by the Oswestry scale, which showed a preoperative average of 59% and postoperative average of 12.4% (P<0.05. A significant improvement in the average slip angle from 54.66% to 9.5% (35% to 0% was found. No major complications such as infection, neurological damage or material breaks were observed.Conclusion:The reduction of high degree listhesis instrumenting only the affected level produces good results, with good control of pain and functional improvement of patients. However, a larger follow-up is required to better evaluation.

  11. Constructing and sampling directed graphs with given degree sequences

    Kim, H; Bassler, K E; Toroczkai, Z

    2011-01-01

    The interactions between the components of complex networks are often directed. Proper modeling of such systems frequently requires the construction of ensembles of digraphs with a given sequence of in- and out-degrees. As the number of simple labeled graphs with a given degree sequence is typically very large even for short sequences, sampling methods are needed for statistical studies. Currently, there are two main classes of methods that generate samples. One of the existing methods first generates a restricted class of graphs, then uses a Markov Chain Monte-Carlo algorithm based on edge swaps to generate other realizations. As the mixing time of this process is still unknown, the independence of the samples is not well controlled. The other class of methods is based on the Configuration Model that may lead to unacceptably many sample rejections due to self-loops and multiple edges. Here we present an algorithm that can directly construct all possible realizations of a given bi-degree sequence by simple di...

    Full Text Available The acquisition of both transversal and specific competences cannot be achieved using conventional methodologies. New methodologies must be applied that promote the necessary competences for proper professional development. Interdisciplinary projects can be a suitable tool for competence-based learning. A priori, this might be complicated, as subjects are traditionally studied at the university level in isolated compartments, with a fragmented structure. Taking advantage of the creation of new degree programs in Mechanical Engineering and Electronic Engineering and Industrial Automation, in the 2010-11 academic year we decided to add an interdisciplinary project (IP to our teaching methodology. The importance of this project lies in the fact that it requires the participation of all the courses in all the academic years in the degree program. The present article explains the methodology used in the interdisciplinary project and how it was implemented in the first year of the Mechanical Engineering and Electronic Engineering and Industrial Automation degree programs. Furthermore, an evaluation is conducted of all four years of the interdisciplinary project, revealing the main problems with its execution and how they have been addressed.

    2009-01-01

    Let n and k (n ≥ k > 1) be two non-negative integers. A k-multi-hypertournament on n vertices is a pair (V, A), where V is a set of vertices with |V|= n, and A is a set of k-tuples of vertices, called arcs, such that for any k-subset S of V, A contains at least one (at most k!) of the k! k-tuples whose entries belong to S. The necessary and sufficient conditions for a non-decreasing sequence of non-negative integers to be the out-degree sequence (in-degree sequence) of some k-multi-hypertournament are given.

    We investigate degree correlations in two online social networks where users are connected through different types of links. We find that, while subnetworks in which links have a positive connotation, such as endorsement and trust, are characterized by assortative mixing by degree, networks in which links have a negative connotation, such as disapproval and distrust, are characterized by disassortative patterns. We introduce a class of simple theoretical models to analyze the interplay between network topology and the superimposed structure based on the sign of links. Results uncover the conditions that underpin the emergence of the patterns observed in the data, namely the assortativity of positive subnetworks and the disassortativity of negative ones. We discuss the implications of our study for the analysis of signed complex networks.

    DeVos, Matt; Fox, Jacob; McDonald, Jessica; Mohar, Bojan; Scheide, Diego

    2011-01-01

    An immersion of a graph $H$ into a graph $G$ is a one-to-one mapping $f:V(H) \\to V(G)$ and a collection of edge-disjoint paths in $G$, one for each edge of $H$, such that the path $P_{uv}$ corresponding to edge $uv$ has endpoints $f(u)$ and $f(v)$. The immersion is strong if the paths $P_{uv}$ are internally disjoint from $f(V(H))$. It is proved that for every positive integer $t$, every simple graph of minimum degree at least $200t$ contains a strong immersion of the complete graph $K_t$. For dense graphs one can say even more. If the graph has order $n$ and has $2cn^2$ edges, then there is a strong immersion of the complete graph on at least $c^2 n$ vertices in $G$ in which each path $P_{uv}$ is of length 2. As an application of these results, we resolve a problem raised by Paul Seymour by proving that the line graph of every simple graph with average degree $d$ has a clique minor of order at least $cd^{3/2}$, where $c>0$ is an absolute constant. For small values of $t$, $1\\le t\\le 7$, every simple graph of...

    Full Text Available Introduction: Hearing loss (HL is defined as the complete or partial loss of hearing ability. Aims: To characterize (1 the degree of satisfaction among adult and elderly hearing aid (HA users who were treated by a public hearing health service and (2 the relationship between satisfaction and the variables of gender, age, degree of HL, and type of HA. Method: The clinical and experimental study included the administration of the Satisfaction with Amplification in Daily Life (SADL questionnaire to 110 patients who had used HAs for more than 3 months and were 18 years of age or older. Results: Test patients were sex-balanced (48% were women and had a mean age of 67 years. A relatively high incidence of sensorineural moderate HL was detected in the study patients (66% and device B was the most commonly used HA type (48%. No significant differences were evident between HA satisfaction and sex. The importance placed on services/costs and personal image varied between age groups. Correlation was evident at all levels between user satisfaction and amplification. Decreased satisfaction was observed in individuals with severe and/or profound HL. The type of HA used yielded statistically significant differences in the positive effects referring. Conclusion: No correlations were evident between the different factors proposed. HA users exhibited high levels of satisfaction in all SADL areas.

    Full Text Available The main objective of the study is to establish the satisfaction degree of the heavy commercial vehicles market customers. This scientifical endeavour is justified by the major importance given by the producers and distributors of such vehicles to the beneficiaries’ satisfaction, a hich importance factor in the product development, customer relations inprovement and market share growth. After the 2008-2009 financial crisis, when the Romanian heavy commercial vehicles market collapsed, the growth trend was linear and moderat, but the market structure changed significantly. Having on one hand high technological costs, generated by the European legislation on pllution reduction and road safety and, on the other hand, the beneficiaries’ price pressure, the top producers from the deveoped countries focused on the optimization of the cutomers’ satisfaction degree and the development of their loyalty towards the brand. In order to achieve this, there has been developed a selective qualitative research, in the form of a questionnaire, among the most important customers of MHS Truck & Bus SRL – the importer of MAN trucks in Romania. The questions were directed towards obtaining informations regarding the customers’ product perception, identifying the main acquisition motivations and finding the main issues in successfully implementing the main politics of the relational maketing. The obtained results generally showed a good satisfaction result, the main complaints regarding subjects indirectly linked to the distribution, like service performance or road assistance.

    1981-01-01

    Full Text Available Nagahara and Kishimoto [1] studied free ring extensions B(x of degree n for some integer n over a ring B with 1, where xn=b, cx=xρ(c for all c and some b in B(ρ=automophism of  B, and {1,x…,xn−1} is a basis. Parimala and Sridharan [2], and the author investigated a class of free ring extensions called generalized quaternion algebras in which b=−1 and ρ is of order 2. The purpose of the present paper is to generalize a characterization of a generalized quaternion algebra to a free ring extension of degree n in terms of the Azumaya algebra. Also, it is shown that a one-to-one correspondence between the set of invariant ideals of B under ρ and the set of ideals of B(x leads to a relation of the Galois extension B over an invariant subring under ρ to the center of B.

  17. 80 Degrees of Seperation: Landscape in Literature

    Directory of Open Access Journals (Sweden)

    2004-12-01

    Full Text Available Two writers in the early 1900s, Katherine Mansfield in New Zealand and Willa Cather in the United States tallgrass prairie, chronicled both the cultural and physical nuances of their frontiers. Their stories are set in rich textural backdrops, made vivid with their descriptions of natural environments. These descriptions provide the context for this paper's exploration. The dense and evocative imagery of these two writers provides a point of departure for a comparison of the two landscapes. The agricultural settlement patterns and natural systems of the New Zealand bush and farmland and those of the United States tallgrass prairie invite comparison. Mansfield's and Cather's narratives provide the guide for this study, capturing the subtle differences and underlying similarities of the textures and patterns of these two landscapes, while emphasising the differences in colour and scale. The degrees of separation are not as distinct as the 80 degrees of latitude that lie between them. Instead there is a myriad of subtle, rather than singular, differentiations. This visual analysis is not intended to address the significant cultural differences of these two places. Rather, it is a study of visual distinctions and similarities guided by the environmental qualities identified by a native author from each locale: Mansfield (New Zealand bush and farmland, and Cather (United States tallgrass prairie. Guided by their words, my own investigation of place is a graphic exploration of the physical environment: the line, form, pattern, texture, colour, light and spatial qualities of each landscape.

    The degree-day method is one of the well-known and the simplest methods used in the Heating, Ventilating and Air-Conditioning industry to estimate heating and cooling energy requirements. In this study, the heating and cooling degree-days for Turkey are determined by using long-term recent measured data. Five different base temperatures ranging from 14 to 22 deg C are chosen in the calculation of heating degree-days. In the case of cooling degree-days, 6 different base temperatures in the range of 18 to 28 deg C are used. Yearly heating and cooling degree-days are given both in tabular form and as counter-maps for all the provinces of Turkey (78 weather stations). (Author)

  2. Mesodynamics with implicit degrees for freedom

    Lin, Keng-Hua; Germann, Timothy C; Strachan, Alejandro

    2014-01-01

    Mesoscale phenomena -- involving a level of description between the finest atomistic scale and the macroscopic continuum -- can be studied by a variation on the usual atomistic-level molecular dynamics (MD) simulation technique. In mesodynamics, the mass points, rather than being atoms, are mesoscopic in size, for instance representing the centers of mass of polycrystalline grains or molecules. In order to reproduce many of the overall features of fully atomistic MD, which is inherently more expensive, the equations of motion in mesodynamics must be derivable from an interaction potential that is faithful to the compressive equation of state, as well as to tensile de-cohesion that occurs along the boundaries of the mesoscale units. Moreover, mesodynamics diffrers from Newton's equations of motion in that dissipation -- the exchange of energy between mesoparticles and their internal degrees of freedom (DoFs) -- must be described, and so should the transfer of energy between the internal modes of neighboring me...

    2005-12-01

    This paper discussed the evaluation problem of image scrambling degree (ISD). Inspired by the evaluation method of image texture characteristics, three new metrics for assessing objectively the ISD were proposed. The first method utilized the performance of energy concentration of Walsh transformation (WT), which took into account the properties that a good ISD measurement method should be contented. The second method used angular second moment (ASM) of image gray level co-occurrence matrix (GLCM). The third method combined the entropy of GLCM with image texture characteristic. Experimental results show that the proposed metrics are effective to assess the ISD, which correlates well with subjective assessment. Considering the computational complexity, the first evaluation method based on WT is remarkably superior to the method based on ASM and GLCM in terms of the time cost.

    The recent emphasis on a realist ontology that cannot be overshadowed by subjectivist or relativist perspectives seems to have a number of consequences for psychology as well. My attempt here is to analyse the relationship between happiness as a state of the individual and the states of the external world and the brain events related to (or, in some hypotheses, causally responsible for) its occurrence. It can be maintained that different degrees of realism are suitable to describe the states of happiness and this fact might have relevant psychological implications, namely for the so-called positive psychology. This is especially true now that there are methods available to induce subjective states of happiness unrelated to the external conditions usually taken to be linked to such states. PMID:27536261

It can be maintained that different degrees of realism are suitable to describe the states of happiness and this fact might have relevant psychological implications, namely for the so-called positive psychology. This is especially true now that there are methods available to induce subjective states of happiness unrelated to the external conditions usually taken to be linked to such states.

    Full Text Available Deciding on a university degree is undoubtedly a difficult choice. This situation brings about fear of failing and disappointing yourself and others, which is a common feeling among high school students, becoming a source of anxiety and stress. This demonstrates the need for an appropriate vocational and professional guidance. In Cuba, this subject is gaining importance, since a greater number of youngsters have the opportunity to choose from more professions; thus, deciding on one or the other is a problem of great practical and social impact. Vocational guidance and training in the Cuban educational context aims to reaffirm the inclination of youth towards medical studies, where they fully develop their potential, on the basis of consolidating values and feelings, and a high social, moral and unconditional commitment to the practice of the profession. This paper presents various issues that currently affect vocational guidance and the role of each of the major participants in the process itself.

  8. On degree bounds for separating invariants

    Let a group $G$ act on a finite dimensional vector space $V$ over an algebraically closed field $K$ of characteristic $p$. Then $\\beta_{\\sep}(G)$ is the minimal number such that, for any $V$, the invariants of degree less or equal than this number have the same separating properties as the whole invariant ring $K[V]^{G}$. Derksen and Kemper have shown $\\beta_{\\sep}(G)\\le |G|$. We show $\\beta_{\\sep}(G)=|G|$ for $p$-groups and cyclic groups, and $\\beta_{\\sep}(G)=\\infty$ for infinite unipotent groups. We also show $\\beta_{\\sep}(G)\\le \\beta_{\\sep}(G/N)\\beta_{\\sep}(N)$ for a normal divisor $N$ of finite index.

    Numerous crystalline materials, including those of bioorganic origin, comprise incommensurate sublattices whose mutual arrangement is described in a superspace framework exceeding three dimensions. We report direct observation by neutron diffraction of superspace symmetry breaking in a solid-solid phase transition of an incommensurate host-guest system: the channel inclusion compound of nonadecane/urea. Strikingly, this phase transition generates a unit cell doubling that concerns only the modulation of one substructure by the other-an internal variable available only in superspace. This unanticipated pathway for degrees of freedom to rearrange leads to a second phase transition, which again is controlled by the higher dimensionality of superspace. These results reveal nature's capacity to explore the increased number of phases allowed in aperiodic crystals.

    The investigation of submesoscale eddies and fronts is one of the leading oceanographic topics at the Ocean Sciences Meeting 2016. In order to observe these small and short-lived phenomena, planes equipped with high-resolution cameras and fast vessels were deployed during the Submesoscale Experiments (SubEx) leading to some of the first high-resolution observations of these eddies. In a future experiment, a zeppelin will be used the first time in marine sciences. The relevance of submesoscale processes for the oceans and the work of the eddy hunters is described in the fascinating 9-minute long 360 degree fulldome production Clockwork Ocean. The fully animated movie is introduced in this presentation taking the observer from the bioluminescence in the deep ocean to a view of our blue planet from space. The immersive media is used to combine fascination for a yet unknown environment with scientific education of a broad audience. Detailed background information is available at the parallax website www.clockwork-ocean.com. The Film is also available for Virtual Reality glasses and smartphones to reach a broader distribution. A unique Mobile Dome with an area of 70 m² and seats for 40 people is used for science education at events, festivals, for politicians and school classes. The spectators are also invited to participate in the experiments by presenting 360 degree footage of the measurements. The premiere of Clockwork Ocean was in July 2015 in Hamburg, Germany and will be worldwide available in English and German as of fall 2015. Clockwork Ocean is a film of the Helmholtz-Zentrum Geesthacht produced by Daniel Opitz and Ralph Heinsohn.

    The forced vibration of dynamic systems with motion stops is relevant to many practical engineering problems. Several applications were identified in the field of mechanical engineering: structures having clearances, bolted junctions, or rods inside guiding grids. Such mechanical systems, when subjected to harmonic excitation, may not necessarily behave in a periodic way, and the loss of stability of their periodic motion is often a precursor for much more complex nonlinear behaviour. Many numerical, analytical and experimental studies have been carried out on the dynamics of these impacting systems. In particular, the behaviour of single degree of freedom (d.o.f.) impact oscillators has been extensively studied. Phenomena like attractor coexistence, subharmonic bifurcation, and chaos were identified in many earlier papers. The classical pattern of flip bifurcation cascade was observed numerically by Shaw and Holmes, and the Feigenbaum scenario of transition to chaos was confirmed. Others also proved that such systems can undergo ``grazing bifurcation`` and that they could lead to chaotic behaviour. Peterka and Vacik even provided bounds of chaotic responses with the help of an analogue computer. Experiments were also carried out on models, like impact pendulums, whose dynamics can be approximately fitted by a single d.o.f. impact oscillator. Other authors conducted investigations into the existence and stability of periodic solutions. Most of these studies were dedicated to the single impact periodic responses of single d.o.f. impact oscillators. The purpose of this paper is to expand the scope of these analytic investigations. This expansion will take two directions, considering first an arbitrarily large number of degrees of freedom in the oscillating structure, and secondly an arbitrary finite number of impacts per period. Thus, the methods presented here could be applied in the study of any finite impact periodic motions of any dynamic impacting system.

    2005-01-01

    Objective: To investigate the effect of 360-degree retinectomy for severe ocular rupture and evaluate the related factors associated with prognosis.Methods: A retrospective analysis was performed on 28 consecutive patients, 18 men and 10 women, with severe ocular rupture admitted to the Chinese PLA General Hospital between January 1999 and January 2002. The patients' ages ranged from 16 to 58 years, mean 29.5years. All operations were performed by the first author.All patients underwent standard 3-port pars plana vitrectomy with scleral encircling buckle,endophotocoagulation, and tamponaded with silicone oil.Lensectomy were performed on 15 eyes. 360-degree retinotomy and retinectomy were performed at anterior equator on 16 eyes, and posterior equator on 12 eyes.Results: During operation, all patients were confirmed to have vitreous hemorrhage and retinal detachment, in which hemorrhagic ciliary body detachment was found in 9 eyes, suprachoroidal hemorrhage in 12 eyes,retinal twisting like flower stalk in 11 eyes, and retinal incarceration in 17 eyes. Postoperative follow-up was conducted in 26 cases, ranged from 6 months to 46 months.Retinal reattachment achieved in 20 eyes (76. 9%), in which three patients' retina was reattached after revitrectomy. The silicone oil was removed at the fourth month in 8 eyes postoperatively. Corrected visual acuity of 0.02 or more was in 14 eyes (70. 0%) among the 20patients with reattached retina. Visual acuity of 0.05 or more was in 7 eyes ( 35.0 % ), and 0.1 or more was in 3eyes. The best visual acuity was 0.3 in 1 eye.Conclusions: Retinectomy may improve the prognosis of severe ocular rupture and save the visual function of some patients.

Maltepe University School of Medicine Department of Ophthalmology, Istanbul, Turkey. Comparative case series. Eyes were assigned to 2.2 mm microcoaxial phacoemulsification using the torsional mode with a 22-degree bent tip (Group 1) or a 12-degree bent tip (Group 2). The primary outcome measures were ultrasound time (UST), cumulative dissipated energy (CDE), longitudinal and torsional ultrasound (US) amplitudes, mean surgical time, mean volume of balanced salt solution used, and surgical complications. Both groups included 45 eyes. The mean UST, CDE, longitudinal US amplitude, and torsional US amplitude were 65 seconds ± 27.23 (SD), 11.53 ± 6.99, 0.22 ± 0.26, and 42.86 ± 15.64, respectively, in Group 1 and 84 ± 45.04 seconds, 16.68 ± 10.66, 0.48 ± 0.68, and 46.27 ± 14.74, respectively, in Group 2. The mean UST, CDE, and longitudinal amplitudes were significantly lower in Group 1 (P=.003, P=.008, and P=.022, respectively). The mean volume of balanced salt solution was 73.33 ± 28.58 cc in Group 1 and 82.08 ± 26.21 cc in Group 2 (P=.134). Torsional phacoemulsification performed with 22-degree bent tips provided more effective lens removal than 12-degree bent tips, with a lower UST and CDE. Copyright © 2013 ASCRS and ESCRS.

    With an average 40% of all physics baccalaureate degree recipients opting not to enter graduate school, it is imperative that departments build robust programs that prepare students for a broad range of career paths. However, the default focus of many departments is on preparing students for entry into advanced physics degree programs. Based on the statistical evidence and need for attention on students entering the workforce, the American Institute of Physics (AIP) has undertaken an NSF-funded research effort to understand, compile and disseminate effective practices for preparing undergraduate physics students to enter the STEM workforce upon graduation. The project entailed site visits to eight schools with strong records of students entering STEM fields, in order to discern effective practices in recruitment and preparation of students for those opportunities. We have developed targeted information to engage the students themselves, the faculty advisors, mentors and career professionals who have direct contact with the students, and the administrative ``decision-makers.'' Each of these groups requires information that addresses their particular roles in the collaborative process that will lead to not only an increase in the numbers of students who enter the STEM workforce, but in the quality preparation of those students. The tools for each of these groups will be discussed, with special emphasis on a set of career tools for students and their mentors. This project is funded by NSF Grant #1011829.

    Polarimetric techniques are widespread employed in many research fields as optics, medicine or biology. In this sense, the use of polarimeters has significantly increased, being a tool with huge perspectives of future. As a consequence, the spreading of the basic knowledge of this topic becomes interesting for many professionals and a master studies is an excellent environment to this aim. We are participating in a mandatory laboratory subject (Laboratory of Optics, LO) of a Master degree in Photonics with an experiment on polarization. In particular, the main structure of the experiment has been built around of a polarimeter set-up. Basically, we use a He-Ne laser beam, a polarization state generator and a polarization state detector. The experimental measurements are acquired by means of a photometer connected to a computer and processed by an own developed software. It allows us to obtain a complete description of any polarizing element tested. In combination with the laboratory work, it is provided a mathematical description of the polarization theory, the Stokes-Mueller formalism, which gives us the base required for a fully understand of the experiment. Throughout this work, we explain the polarimeter experiment structure and the achievements reached by students. We want to emphasize that a different degree of expertise and knowledge in function of the specific background of every student is provided. However, a minimum knowledge level is reached for all students, including among others, the improvement in the scientific, communicative or interdisciplinary competences.

    The effective degrees of freedom of the quark-gluon plasma are studied in the temperature range {approx}(1-2)T{sub c}. We show that including light bosonic states one can reproduce the pressure and energy density of the quark-gluon plasma obtained by lattice simulations. The number of the bosonic states required is at most of the order of 20, consistent with the number of light mesonic states and in disagreement with a recently proposed picture of the quark-gluon plasma as a system populated with exotic bound states. We also constrain the quark quasiparticle chiral invariant mass to be {approx}300 MeV. Some remarks regarding the role of the gluon condensation and the baryon number-strangeness correlation are also presented.

    Full Text Available In modern packaging, printing industry, due to effects of the properties of the strip itself and the ambient light, strip background color and the color of the printing line, the low contrast boundaries of the strip on both sides and so on, the traditional digital qualitative detection and control to the correction system does not meet the comprehensive requirements. This paper aims to study the detection of a continuous line, discontinuous line and color dividing line on the strip, and because of low contrast between background color and dividing line, we proposed an innovative solution and implementation. This article discusses a new algorithm basing on maximum degree of recognition and optimal light source search algorithm, and we simulated this in MATLAB, finally, we completed the physical testing of the overall system.

    Quantum systems are important resources for quantum computer. Different from previous encoding forms using quantum systems with one degree of freedom (DoF) or two DoFs, we investigate the possibility of photon systems encoding with three DoFs consisting of the polarization DoF and two spatial DoFs. By exploring the optical circular birefringence induced by an NV center in a diamond embedded in the photonic crystal cavity, we propose several hybrid controlled-NOT (hybrid CNOT) gates operating on the two-photon or one-photon system. These hybrid CNOT gates show that three DoFs may be encoded as independent qubits without auxiliary DoFs. Our result provides a useful way to reduce quantum simulation resources by exploring complex quantum systems for quantum applications requiring large qubit systems.

    Full Text Available Canadian university students tend to endorse employment-related reasons for attending university ahead of other reasons such as personal satisfaction or intellectual growth. In the present study, first- and fourth-year students from a mid-sized Canadian university reported on the benefits they expected to receive from their degree and rated their relative importance. These open-ended responses suggested that both groups of students placed a greater emphasis on benefits related to career preparation and economic advancement than those associated with learning and self-improvement. However, when asked to evaluate the importance of a comprehensive list of degree-related benefits both groups of students endorsed the value of many of them, including those related to learning and self-improvement. Our results suggest the importance of methodology in gathering data about this issue, and we consider them in light of current concerns with helping students to understand the full value of their degree. Les étudiants des universités canadiennes ont tendance à accepter les raisons qui se rapportent à l’emploi pour justifier les études universitaires avant d’autres raisons telles que la satisfaction personnelle ou la croissance intellectuelle. Dans la présente étude, des étudiants de première année et de quatrième année d’une université canadienne de taille moyenne ont indiqué les avantages qu’ils s’attendaient à obtenir avec leur diplôme et les ont classés par ordre d’importance. Ces réponses ouvertes suggèrent que les deux groupes d’étudiants ont attribué une plus grande importance aux avantages liés à la préparation de leur carrière et à l’avancement économique qu’à ceux liés à l’apprentissage et à l’amélioration personnelle. Toutefois, quand on leur a demandé d’évaluer l’importance d’une liste complète d’avantages liés à l’obtention d’un diplôme, les deux groupes d’étudiants ont

    The growth and development of crops is commonly regarded as a function of time alone. However, this approach can be inadequate due to temperatures which vary from year to year caused by global climate change. This prompted the development of the growing degree day concept, which incorporates information on both the passage of time and the temperature experienced by the crop plant during that time. Crop water requirements, which are estimated by multiplying reference evapotranspiration values by a crop-specific coefficient, play a crucial role in the management of hydrologic cycles on arable land. Consequently, it would be useful to identify the relationships between cumulative growing degree days and reference evapotranspiration, in order to develop new methods for predicting crop growth and development periods and calculating reference evapotranspiration. This paper describes annual trends in cumulative growing degree days values and their impact on grape growth. Three different methods for calculating cumulative growing degree days values were evaluated as well. Several key findings were achieved. First, for the period between 1952 and 1995, the cumulative growing degree days values for specific days of the year were normally distributed. Second, the relationship between the relative cumulative growing degree days value and the passage of time can be accurately described by using a cubic polynomial function. Third, the day-to-day change in the average relative cumulative reference evapotranspiration can be described using an exponential function of time, which can be used to calculate the relative cumulative reference evapotranspiration value for any given day of the year. Fourth, there was a significant correlation between the relative cumulative growing degree days and cumulative reference evapotranspiration values during the period between grape budding and maturity, which can be described using a cubic polynomial function. Finally, a new method for

    This is a sub-section of the 'geometrically improved, color enhanced' version of the 360-degree panorama heretofore known as the 'Gallery Pan', the first contiguous, uniform panorama taken by the Imager for Mars Pathfinder (IMP) over the course of Sols 8, 9, and 10. Different regions were imaged at different times over the three Martian days to acquire consistent lighting and shadow conditions for all areas of the panorama.The IMP is a stereo imaging system that, in its fully deployed configuration, stands 1.8 meters above the Martian surface, and has a resolution of two millimeters at a range of two meters. In this geometrically improved version of the panorama, distortion due to a 2.5 degree tilt in the IMP camera mast has been removed, effectively flattening the horizon.The IMP has color capability provided by 24 selectable filters -- twelve filters per 'eye'. Its red, green, and blue filters were used to take this image. The color was digitally balanced according to the color transmittance capability of a high-resolution TV at the Jet Propulsion Laboratory (JPL), and is dependent on that device. In this color enhanced version of the panorama, detail in surface features are brought out via changes to saturation and intensity, holding the original hue constant. A threshold was applied to avoid changes to the sky.At left is a Lander petal and a metallic mast which is a portion of the low-gain antenna. Misregistration in the antenna and other Lander features is due to parallax in the extreme foreground. Another Lander petal is at the right, showing the fully deployed forward ramp.Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals.

  3. Improving Scientific Writing in Undergraduate Geosciences Degrees Through Peer Review

    Science.gov (United States)

    Day, E. A.; Collins, G. S.; Craig, L.

    2016-12-01

    In the British educational system, students specialise early. Often geoscience undergraduates have not taken a class that requires extended writing since they were sixteen years old. This can make it difficult for students to develop the written skills necessary for a geoscience degree, which often has assessments in the form of essays and reports. To improve both the writing and editing skills of our undergraduates we have introduced a peer review system, in which seniors review the work of first year students. At Imperial College London we set written coursework in every year of the degree. Communication is taught and assessed in many courses. There are two major modules with substantial written components that bookend the undergraduate degree at Imperial; the freshmen all write an assessed essay, while all seniors take 'Science Communication', a course that aims to prepare them for a range of possible careers. In the 2015-16 academic year we linked these courses by introducing a modified form of peer marking and instruction. Seniors had to complete reviews of draft first year essays for credit in Science Communication. These reviews are completed for the department 'journal' and introduce the first and fourth years to the nature of peer review. Seniors learn how to critically, but kindly, evaluate the work of other students, and are also prepared for potentially submitting their senior theses to journals. Reviews were managed by volunteer seniors, who acted as associate editors. They allocated anonymous reviewers and wrote decision letters, which were sent to the freshmen before their final assessed essay submission. Ultimately the fourth year reviews were formally assessed and graded by members of staff, as were the revised and resubmitted first year essays. Feedback for both courses has improved since the introduction of student reviews of essays. The markers of the freshman essay have also commented on the improvement in the standard of the writing and a

    (Abridged)One of the fundamental challenges for astrophysics in the 21st century is finding a way to untangle the physical processes that govern galaxy formation and evolution. Given the importance and scope of this problem, the multi-wavelength astronomical community has used the past decade to build up a wealth of information over specific extragalactic deep fields to address key questions in galaxy formation and evolution. These fields generally cover at least 10square degrees to facilitate the investigation of the rarest, typically most massive, galaxies and AGN. Furthermore, such areal coverage allows the environments to be fully accounted for, thereby linking the single halo to the two-halo terms in the halo occupation distribution. Surveys at radio wavelengths have begun to lag behind those at other wavelengths, especially in this medium-deep survey tier. However, the survey speed offered by the JVLA means that we can now reach a point where we can begin to obtain commensurate data at radio wavelengths...

  13. Constraining the roughness degree of slip heterogeneity

    KAUST Repository

    Causse, Mathieu

    2010-05-07

    This article investigates different approaches for assessing the degree of roughness of the slip distribution of future earthquakes. First, we analyze a database of slip images extracted from a suite of 152 finite-source rupture models from 80 events (Mw = 4.1–8.9). This results in an empirical model defining the distribution of the slip spectrum corner wave numbers (kc) as a function of moment magnitude. To reduce the “epistemic” uncertainty, we select a single slip model per event and screen out poorly resolved models. The number of remaining models (30) is thus rather small. In addition, the robustness of the empirical model rests on a reliable estimation of kc by kinematic inversion methods. We address this issue by performing tests on synthetic data with a frequency domain inversion method. These tests reveal that due to smoothing constraints used to stabilize the inversion process, kc tends to be underestimated. We then develop an alternative approach: (1) we establish a proportionality relationship between kc and the peak ground acceleration (PGA), using a k−2 kinematic source model, and (2) we analyze the PGA distribution, which is believed to be better constrained than slip images. These two methods reveal that kc follows a lognormal distribution, with similar standard deviations for both methods.

    Zirconium has recently garnered attention for use as a diffusion barrier between U–Mo nuclear fuels and Al cladding alloys. Interdiffusion and reactions between Zr and Al, Al-2 wt.% Si, Al-5 wt.% Si or AA6061 were investigated using solid-to-solid diffusion couples annealed in the temperature range of 425 degrees to 625 degrees C. In the binary Al and Zr system, the Al3Zr and Al2Zr phases were identified, and the activation energy for the growth of the Al3Zr phase was determined to be 347 kJ/mol. Negligible diffusional interactions were observed for diffusion couples between Zr vs. Al-2 wt.% Si, Al-5 wt.% Si and AA6061 annealed at or below 475 degrees C. In diffusion couples with the binary Al–Si alloys at 560 degrees C, a significant variation in the development of the phase constituents was observed including the thick t1 (Al5SiZr2) with Si content up to 12 at.%, and thin layers of (Si,Al)2Zr, (Al,Si)3Zr, Al3SiZr2 and Al2Zr phases. The use of AA6061 as a terminal alloy resulted in the development of both T1 (Al5SiZr2) and (Al,Si)3Zr phases with a very thin layer of (Al,Si)2Zr. At 560 degrees C, with increasing Si content in the Al–Si alloy, an increase in the overall rate of diffusional interaction was observed; however, the diffusional interaction of Zr in contact with multicomponent AA6061 with 0.4–0.8 wt.% Si was most rapid.

    This 360-degree panorama was taken in stereo by the deployed Imager for Mars Pathfinder (IMP) on Sol 3. 3D glasses (red left lens, blue right lens) are necessary to help identify surface detail. All three petals, the perimeter of the deflated airbags, deployed rover Sojourner, forward and backward ramps and prominent surface features are visible, including the double Twin Peaks at the horizon. Sojourner would later investigate the rock Barnacle Bill just to its left in this image, and the larger rock Yogi at its forward right.The IMP is a stereo imaging system with color capability provided by 24 selectable filters -- twelve filters per 'eye.' It stands 1.8 meters above the Martian surface, and has a resolution of two millimeters at a range of two meters. Stereoscopic imaging brings exceptional clarity and depth to many of the features in this image, particularly the ridge beyond the far left petal and the large rock Yogi. The curvature and misalignment of several section are due to image parallax.Mars Pathfinder is the second in NASA's Discovery program of low-cost spacecraft with highly focused science goals. The Jet Propulsion Laboratory, Pasadena, CA, developed and manages the Mars Pathfinder mission for NASA's Office of Space Science, Washington, D.C. JPL is a division of the California Institute of Technology (Caltech).

  17. Degree and connectivity of the Internet's scale-free topology

    2011-01-01

    This paper theoretically and empirically studies the degree and connectivity of the Internet's scale-free topology at an autonomous system (AS)level. The basic features of scale-free networks influence the normalization constant of degree distribution p(k). It develops a new mathematic model for describing the power-law relationships of Internet topology. From this model we theoretically obtain formulas to calculate the average degree, the ratios of the kmin-degree (minimum degree)nodes and the km.-degree (maximum degree)nodes, and the fraction of the degrees (or links)in the hands of the richer (top best-connected)nodes. It finds that the average degree is larger for a smaller power-law exponent λ and a larger minimum or maximum degree. The ratio of the kmin-degree nodes is larger for larger a and smaller kmin or kmax. The ratio of the kmax-degree ones is larger for smaller λ and kn,ax or larger kmin. The richer nodes hold most of the total degrees of Internet AS-level topology. In addition, it is revealed that the increased rate of the average degree or the ratio of the kmin-degree nodes has power-law decay with the increase of kmin. The ratio of the km.-degree nodes has a power-law decay with the increase of k, and the fraction of the degrees in the hands of the richer 27% nodes is about 73% (the'73/27 rule'). Finally, empirically calculations are made, based on the empirical data extracted from the Border Gateway Protocol, of the average degree, ratio and fraction using this method and other methods, and find that this method is rigorous and effective for Internet AS-level topology.

    Robotic rehabilitation is a currently underutilised field with the potential to allow huge cost savings within healthcare. Existing rehabilitation exoskeletons oversimplify the importance of movement of the hand while undertaking everyday tasks. Within this study, an investigation was undertaken to establish the extent to which the degrees of freedom within the palm affect ability to undertake everyday tasks. Using a 5DT data glove, bend sensing resistors and restrictors of palm movement, 20 participants were recruited to complete tasks that required various hand shapes. Collected data was processed and palm arching trends were identified for each grasping task. It was found that the extent of utilizing arches in the palm varied with each exercise, but was extensively employed throughout. An exoskeleton was subsequently designed with consideration of the identified palm shapes. This design included a number of key features that accommodated for a variety of hand sizes, a novel thumb joint and a series of dorsally mounted servos. Initial exoskeleton testing was undertaken by having a participant complete the same exercises while wearing the exoskeleton. The angles formed by the user during this process were then compared to those recorded by 2 other participants who had completed the same tasks without exoskeleton. It was found that the exoskeleton was capable of forming the required arches for completing the tasks, with differences between participants attributed to individual ergonomic differences.

    Let F : P^N --> P^N be a dominant rational map. The dynamical degree of F is the quantity d_F = lim (deg F^n)^(1/n). When F is defined over a number field, we define the arithmetic degree of an algebraic point P to be a_F(P) = limsup h(F^n(P))^(1/n) and the canonical height of P to be h_F(P) = limsup h(F^n(P))/n^k d_F^n for an appropriately chosen integer k = k_F. In this article we prove some elementary relations and make some deep conjectures relating d_F, a_F(P), and h_F(P). We prove our conjectures for semisimple monomial maps.

  2. Impact of degree truncation on the spread of a contagious process on networks

    CERN Document Server

    Harling, Guy

    2016-01-01

    Understanding how person-to-person contagious processes spread through a population requires accurate information on connections between population members. However, such connectivity data, when collected via interview, is often incomplete due to partial recall, respondent fatigue or study design, e.g., fixed choice designs (FCD) truncate out-degree by limiting the number of contacts each respondent can report. Past research has shown how FCD truncation affects network properties, but its implications for predicted speed and size of spreading processes remain largely unexplored. To study the impact of degree truncation on spreading processes, we generated collections of synthetic networks containing specific properties (degree distribution, degree-assortativity, clustering), and also used empirical social network data from 75 villages in Karnataka, India. We simulated FCD using various truncation thresholds and ran a susceptible-infectious-recovered (SIR) process on each network. We found that spreading proce...

As a result, two accepted claims or theories belonging to two different sciences may not necessarily carry the same degree of truthfulness. Examining the different methodologies of deriving claims in the sciences of ʿaqīdah (Islamic Creed, fiqh (Islamic Jurisprudence and physics, the study shows that ʿaqīdah provides a holistic understanding of the universe. Physics falls short of interpreting physical phenomena unless these phenomena are looked at through the ʿaqīdah holistic view. Left to itself, error may creep into laws of physics due to the methodology of conducting the physical experiments, misinterpreting the experimental results, or accepting invalid assumptions. As for fiqh, it is found that apart from apparent errors, fiqh views cannot be falsified. It is, therefore, useful to consider ʿaqīdah as a master science which would permit all other sciences to live in harmony.

  4. Classification of infrastructure networks by neighborhood degree distribution

    CERN Document Server

    Giustolisi, O; Ridolfi, L

    2016-01-01

    A common way of classifying network connectivity is the association of the nodal degree distribution to specific probability distribution models. During the last decades, researchers classified many networks using the Poisson or Pareto distributions. Urban infrastructures, like transportation (railways, roads, etc.) and distribution (gas, water, energy, etc.) systems, are peculiar networks strongly constrained by spatial characteristics of the environment where they are constructed. Consequently, the nodal degree of such networks spans very small ranges not allowing a reliable classification using the nodal degree distribution. In order to overcome this problem, we here (i) define the neighborhood degree, equal to the sum of the nodal degrees of the nearest topological neighbors, the adjacent nodes and (ii) propose to use neighborhood degree to classify infrastructure networks. Such neighborhood degree spans a wider range of degrees than the standard one allowing inferring the probabilistic model in a more re...

    Howard, Claire; Dupont, Simon

    2014-01-01

    Background: Chronic obstructive pulmonary disease (COPD) is a costly long-term condition associated with frequent Accident and Emergency (A&E) and hospital admissions. Psychological difficulties and inadequate self-management can amplify this picture. Aims: To compare a cognitive-behavioural manual versus information booklets (IB) on health service use, mood and health status. Methods: Two hundred and twenty-two COPD patients were randomly allocated to receive either the COPD breathlessness manual (CM) or IB. They were instructed to work through their programme at home, over 5 weeks. Guidance from a facilitator was provided at an initial home visit plus two telephone call follow-ups. Results: After 12 months, total A&E visits had reduced by 42% in the CM group, compared with a 16% rise in the IB group. The odds of people in the IB group attending A&E 12 months post-intervention was 1.9 times higher than for the CM group (CI 1.05–3.53). Reduction in hospital admissions and bed days were greatest in the CM group. At 6 months, there were significantly greater improvements in anxiety (F (2,198)=5.612, P=0.004), depression (F (1.8,176.1)=10.697, P⩽0.001) and dyspnoea (F (2,198)=18.170, P⩽0.001) in the CM group. Estimated savings at 12 months were greatest in the CM group, amounting to £30k or £270 per participant. Conclusion: The COPD manual, which addresses physical and mental health, is a straightforward cost-effective intervention that is worth offering to COPD patients within primary or secondary care.

    The BESIII experiment at the BEPCII electron positron collider at IHEP (Beijing) is collecting data in the charm-τ mass region. Electron positron collisions are a very well suited environment for the study of initial state radiation (ISR). However, the photons from ISR are strongly peaked towards small polar angles and are currently detected with limited efficiency. In order to increase the detection efficiency of ISR photons, we are developing small-size calorimeters to be placed in the very forward and backward regions. Each detector will consist of two 4×3 arrays of 1×1×14 cm3 LYSO crystals. A 1 cm gap separating each of the two arrays will reduce the contamination from background at very low angles. The scintillation light will be collected by silicon photomultipliers (SiPMs). The expected event rate in the MHz range requires flash ADCs recording the preamplified SiPM outputs.The digitized waveforms will be analyzed in realtime yielding data reduction and pile-up detection. This high bandwidth data stream will be transmitted via optical fibers to FPGA-based hardware performing sub-event building, buffering, and event correlation with the BESIII trigger. The sub-events with a corresponding trigger will be sent to the BESIII event builder via TCP/IP. A single crystal equipped with a SiPM was instrumented as a prototype detector. Tests with radioactive sources were performed successfully.

    We present definitions of the correlation degree and correlation coefficient of multi-output functions. Two relationships about the correlation degree of multi-output functions are proved. One is between the correlation degree and independency,the other is between the correlation degree and balance. Especially the paper discusses the correlation degree of affine multioutput functions. We demonstrate properties of the correlation coefficient of multi-output functions. One is the value range of the correlation coefficient, one is the relationship between the correlation coefficient and independency, and another is the sufficient and necessary condition that two multi-output functions are equivalent to each other.

    Many real-world networks such as the protein–protein interaction networks and metabolic networks often display nontrivial correlations between degrees of vertices connected by edges. Here, we analyse the statistical methods used usually to describe the degree correlation in the networks, and analytically give linear relation in the degree correlation. It provides a simple and interesting perspective on the analysis of the degree correlation in networks, which is usefully complementary to the existing methods for degree correlation in networks. Especially, the slope in the linear relation corresponds exactly to the degree correlation coefficient in networks, meaning that it can not only characterize the level of degree correlation in networks, but also reflects the speed that the average nearest neighbours’ degree varies with the vertex degree. Finally, we applied our results to several real-world networks, validating the conclusions of the linear analysis of degree correlation. We hope that the work in this paper can be helpful for further understanding the degree correlation in complex networks.

    @@ We introduce a sandpile model driven by degree on scale-free networks, where the perturbation is triggered at nodes with the same degree. We numerically investigate the avalanche behaviour of sandpile driven by different degrees on scale-free networks. It is observed that the avalanche area has the same behaviour with avalanche size. When the sandpile is driven at nodes with the minimal degree, the avalanches of our model behave similarly to those of the original Bak-Tang-Wiesenfeld (BTW) model on scale-free networks. As the degree of driven nodes increases from the minimal value to the maximal value, the avalanche distribution gradually changes from a clean power law, then a mixture of Poissonian and power laws, finally to a Poisson-like distribution. The average avalanche area is found to increase with the degree of driven nodes so that perturbation triggered on higher-degree nodes will result in broader spreading of avalanche propagation.

  10. Theological view of nuclear energy. [Booklet

    Energy Technology Data Exchange (ETDEWEB)

    Pollard, W.G.

    Over half of the matter of the universe is in the form of nuclear power plants, asserts Dr. William Pollard. These nuclear power plants are more commonly known as stars. ''It's a sobering thought that God has more of them than he has of anything else,'' reasons Dr. Pollard. He argues that man has successfully taken dominion over the providential fuels supplied to the earth and, now that he has discovered how to harness nuclear power, it is only natural to take dominion over this inexhaustible energy resource. A scientist and theologian, Dr. Pollard is a consultant to the Institute for Energy Analysis of Oak Ridge Associated Universities in Oak Ridge, TN. He was formerly executive director of Oak Ridge Associated Universities and is a fellow of the American Nuclear Society. He is also an Episcopal priest of 25 years service, a ministry he continues to pursue in retirement. Dr. Pollard calls nuclear energy the most natural of all fuels because it is the most common form of energy occurring in creation. He concludes that to reject such a tremendous gift is ''to submit to fear and to surrender the helps that come from reason.''

    To compare the intraoperative performance and postoperative outcome after microcoaxial torsional phacoemulsification using either a Kelman or balanced phaco tip. Cataracts were treated using 2.2 mm microcoaxial torsional phacoemulsification using either a 45-degree mini-flared Kelman(®) or a 45-degree Intrepid(®) Balanced phaco tip. Intraoperative measurements included total ultrasound (US) time, cumulative dissipated energy (CDE), torsional US time, and balanced salt solution (BSS) use. The central endothelial cell density (ECD) and central corneal thickness (CCT) were evaluated preoperatively and postoperatively 1, 7, and 30d after surgery using noncontact specular microscopy. The 116 enrolled eyes (116 patients) were divided equally between the Kelman and balanced tip groups. Intraoperative measurements showed significantly less total US time, torsional US time, CDE, and BSS use in the balanced group than in Kelman group (Ptip provided more effective lens removal with less total US time, torsional time, CDE, and BSS use, as well as similar changes in ECD with a Kelman tip in all cataract grades. This special designed phaco tip for torsional phacoemulsification provides an alternative phaco tip for many surgeons' preference with straight phaco tip.

    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.

  14. Extending mode switching to multiple degrees of freedom in hand prosthesis control is not efficient.

    2014-01-01

    In recent years, many sophisticated control strategies for multifunctional dexterous hand prostheses have been developed. It was indeed assumed that control mechanisms based on switching between degrees of freedom, which are in use since the 1960's, could not be extended to efficient control of more than two degrees of freedom. However, quantitative proof for this assumption has not been shown. In this study, we adopted the mode switching paradigm available in commercial prostheses for two degree of freedom control and we extended it for the control of seven functions (3.5 degrees of freedom) in a modern robotic hand. We compared the controllability of this scaled version of the standard method to a state of the art pattern recognition based control in an applied online study. The aim was to quantify whether multi-functional prosthetic control with mode switching outperformed pattern recognition in the control of a real prosthetic hand for daily life activities online. Although in simple grasp-release tasks the conventional method performed best, tasks requiring more complex control of multiple degrees of freedom required a more intuitive control method, such as pattern recognition, for achieving high performance.

    2011-01-01

    We study the converse and achievability for the degrees of freedom of the multicellular multiple-input multiple-output (MIMO) multiple access channel (MAC) with constant channel coefficients. We assume L>1 homogeneous cells with K>0 users per cell where the users have M antennas and the base stations are equipped with N antennas. The degrees of freedom outer bound for this L-cell and K-user MIMO MAC is formulated. The characterized outer bound uses insight from a limit on the total degrees of freedom for the L-cell heterogeneous MIMO network. We also show through an example that a scheme selecting a transmitter and performing partial message sharing outperforms a multiple distributed transmission strategy in terms of the total degrees of freedom. Simple linear schemes attaining the outer bound (i.e., those achieving the optimal degrees of freedom) are explores for a few cases. The conditions for the required spatial dimensions attaining the optimal degrees of freedom are characterized in terms of K, L, and th...

    Caenorhabditis elegans has been used as a host for the study of bacteria that cause disease in mammals. However, a significant limitation of the model is that C. elegans is not viable at 37 degrees C. We report that the gonochoristic nematode Panagrellus redivivus survives at 37 degrees C and maintains its life cycle at temperatures up to and including 31.5 degrees C. The C. elegans pathogens Pseudomonas aeruginosa, Salmonella enterica, Staphylococcus aureus, but not Yersinia pseudotuberculosis, reduced P. redivivus lifespan. Of four strains of Burkholderia multivorans tested, one reduced P. redivivus lifespan at both temperatures, one was avirulent at both temperatures and two strains reduced P. redivivus lifespan only at 37 degrees C. The mechanism by which one of these strains killed P. redivivus at 37 degrees C, but not at 25 degrees C, was investigated further. Killing required viable bacteria, did not involve bacterial invasion of tissues, is unlikely to be due to a diffusible, bacterial toxin and was not associated with increased numbers of live bacteria within the intestine of the worm. We believe B. multivorans may kill P. redivivus by a temperature-regulated mechanism similar to B. pseudomallei killing of C. elegans.

    Four different data sets pertaining to the neutral atom environment at 1 AU are presented and discussed. These data sets include neutral solar wind and interstellar neutral atom data from IMAGE/LENA, energetic hydrogen atom data from SOHO/HSTOF and plasma wave data from the magnetometer on ISEE-3. Surprisingly, these data sets are centered between 262 degrees and 292 degrees ecliptic longitude, about 10 degrees - 40 degrees from the upstream interstellar neutral flow direction at 254 degrees resulting from the motion of the Sun relative to the local interstellar cloud. Some possible explanations for this offset, none of which is completely satisfactory, are discussed.

    2004-01-01

    A two-stage 68degreesC/55degreesC anaerobic degradation process for treatment of cattle manure was studied. In batch experiments, an increase of the specific methane yield, ranging from 24% to 56%, was obtained when cattle manure and its fractions (fibers and liquid) were pretreated at 68degrees......C for periods of 36, 108, and 168 h, and subsequently digested at 55degreesC. In a lab-scale experiment, the performance of a two-stage reactor system, consisting of a digester operating at 68degreesC with a hydraulic retention time (HRT) of 3 days, connected to a 55degreesC reactor with 12-day HRT......, was compared with a conventional single-stage reactor running at 55degreesC with 15-days HRT. When an organic loading of 3 g volatile solids (VS) per liter per day was applied, the two-stage setup had a 6% to 8% higher specific methane yield and a 9% more effective VS-removal than the conventional single...

  19. Thermal distortion testing of a 90-degree deployment hinge

    Lininger, Lance

    2003-09-01

    Virtually all modern spacecraft have at least one (if not many) deployable items, some of which require a high degree of positional accuracy and repeatability. There are many variables that affect the deployment performance, and often the most critical and difficult variable to quantify is the affect of the thermal environment on the deployment mechanisms. Temperature changes before and after deployment can greatly affect the final deployment position and the subsequent thermal distortion of the mechanism, and it is critical to properly quantify these factors. Historically the affects of temperature change on deployment mechanisms have been evaluated via analysis due to the relative cost and difficulty in performing a test. However, during the design process of a recent Lockheed Martin deployment hinge, the engineers wanted to provide their customer with a more reliable empirical assessment. Thus, it was decided to conduct a thermal distortion and repeatability test on the hinge during the qualification phase. Testing of this nature is very rare for relatively inexpensive deployment hinges and is usually reserved for high precision, actively-latched optical hinges. Results of this testing are presented, along with lessons learned when performing the test.

    Full Text Available Expansive soil in SokooNgawi East Java often gives problems in the building stability. This research aims to study the properties of the soil in the area that mainly related to changes in moisture content in particular the influence of the degree of saturation of the swelling strain. Swelling tests were performed on disturbed soil by means of oedometer at 6.9 kPa overburden pressure. Initial moisture contents used were varied from 15.04% to 42.88%. Swelling strain was measured using overburden pressure 6.9 kPa and swelling pressure obtained from the pressure required to return the sample to the original condition. The test results show that for initial moisture content 15.04 % , γd= 1.471 gr/cm ³,S = 50.70 % the maximum swelling strain were 38.04% and swelling pressure was 2392 kPa. The initial moisture content 42.88%, γd= 0.926 gr / cm ³, S = 65.26 % the minimum swelling strain was 1.68 % and swelling pressure was 34 kPa.

    2003-02-01

    We construct a rejection-free Monte Carlo algorithm for a system with continuous degrees of freedom. We illustrate the algorithm by applying it to the classical three-dimensional Heisenberg model with canonical Metropolis dynamics. We obtain the lifetime of the metastable state following a reversal of the external magnetic field. Our rejection-free algorithm obtains results in agreement with a direct implementation of the Metropolis dynamic and requires orders of magnitude less computational time at low temperatures. The treatment is general and can be extended to other dynamics and other systems with continuous degrees of freedom.

    Full Text Available Syzygium is one of large genera of the flowering plants. In order to simplify the identification, a classification is required, e.g. based on degree of petal fusion, leaf size and fruit size. Due to variations of vegetative and generative characters, a correlation analysis was carried out. The aim of this research is to know the correlation between degree of petal fusion, leaf length and fruit diameter. The result of this research showed that there is positive correlation between those three variables. The increase of leaf size will increase fruit size and petal lobe depth.

    Measurements of the fracture toughness of the production-scale heat (832665) of V-4Cr-4Ti have been performed at 25{degrees}C and {minus}196{degrees}C using compact tension (CT) specimens. Test specimens were vacuum annealed at either 1000{degrees}C for 1 hour (HT1) or 1050{degrees}C for two hours (HT2). Specimens given the HT1 treatment were annealed after final machining, whereas the HT2 specimens received the 1050{degrees}C anneal at Teledyne Wah Chang prior to final machining. Following machining HT2 specimens were then vacuum annealed at 180{degrees}C for two hours to remove hydrogen. Specimens treated using HT1 had a partially recrystallized microstructure and those treated using HT2 had a fully recrystallized microstructure. The fracture toughness at 25{degrees}C was determined by J-integral tests and at {minus}196{degrees}C by ASTM E 399 type tests. Toughness values obtained at {minus}196{degrees}C were converted to J-integral values for comparison to the 25{degrees}C data. The 25{degrees}C fracture toughness was very high with none of the specimens giving valid results per ASTM criteria. Specimens fractured by microvoid coalescence. The fracture toughness at {minus}196{degrees}C was much lower than that at 25{degrees}C and the fracture surface showed predominantly cleavage features. The present results show a transition from ductile to brittle behavior with decreasing test temperature which is not observed from one-third scale Charpy impact tests. The fracture toughness at {minus}196{degrees}C was still quite high, however, at about 75 kJ/m{sup 2}. Delaminations in planes normal to the thickness direction were seen at both test temperatures. Fracture surfaces inside the delaminations exhibited nearly 100% cleavage facets. The cause of the brittle delaminations was not determined, but will be a subject for further investigation.

    Fatty liver is one of the most commonly found disease by abdominal ultrasonography. The status of fatty liver is classified into mild, moderate and severe degrees. The study was conducted to investigate the clinical significance of fatty liver using ultrasonography. Test set consisted of 2,185 patients who visited D healthcare center in Daejeon to receive an abdominal ultrasonic test from January to December 2007. Out of the 2185 patients, 524 patients was diagnosed as fatty liver (290 male and 234 female patients). They were divided into three groups, group I for mild degree. II for moderate degree, and III for severe degree, depending on the echo of liver parenchyma, the sound attenuation, and the visibility of intrahepatic blood vessels and diaphragm. Then the correlation of obesity indices, liver function tests and metabolic syndrome was analyzed for males and females separately. As for the degree of fatty liver, 350 cases (66.8%) were classified as group I, 153 cases (29.2%) as group II, and 21 cases (4.1%) as group III. In addition, severe degree of fatty liver was more frequently found in males than in females. The mean ages of three groups for males were 46.1, 44.5, and 39.1, and those for females were 48.8, 50.2, 52.4, respectively. Males with lower mean ages have severely of fatty liver for both males and females. The results in this study show that the classification into three degrees of fatty liver in ultrasonography practice is helpful to treat and observe the progress of fatty liver. In addition, careful examination is required to measure the severity of fatty liver as well as detection of it. A standardized method to classify the degree of fatty liver is also needed for more objective measurement.

    2016-04-01

    New methods for ultra-high degree spherical harmonic analyses and syntheses have been developed and studied over the past years. The focus group "High-resolution Gravity Modelling", established in 2013 at TU Munich, has implemented ultra-high degree spectral modelling techniques and used successfully to transform high-resolution topography grids of Earth, Moon and Mars into spherical harmonics. For Earth, a new set of 1 arc-min topography models, developed by our group and released under the name Earth2014, was expanded into a spherical harmonic series to degree 10,800. For the 15 arc-sec resolution SRTM15_plus topography and bathymetry, a spectral resolution of degree 43,200 was achieved. For Moon and Mars, topography grids from laser altimetry were harmonically analysed up to degree ~46,000. The spectral representations of the topography grids presented in this contribution are required in the context of spectral gravity forward modelling with ultra-high degree, where the topographic potential is computed as a function of the spherical harmonic series of the topography and its integer powers.

    Full Text Available AIM: To compare the intraoperative performance and postoperative outcome after microcoaxial torsional phacoemulsification using either a Kelman or balanced phaco tip. METHODS: Cataracts were treated using 2.2 mm microcoaxial torsional phacoemulsification using either a 45-degree mini-flared Kelman® or a 45-degree Intrepid® Balanced phaco tip. Intraoperative measurements included total ultrasound (US time, cumulative dissipated energy (CDE, torsional US time, and balanced salt solution (BSS use. The central endothelial cell density (ECD and central corneal thickness (CCT were evaluated preoperatively and postoperatively 1, 7, and 30d after surgery using noncontact specular microscopy. RESULTS: The 116 enrolled eyes (116 patients were divided equally between the Kelman and balanced tip groups. Intraoperative measurements showed significantly less total US time, torsional US time, CDE, and BSS use in the balanced group than in Kelman group (P<0.05. The total US time, torsional US time, CDE, and BSS use were 17.45±14.53s, 16.63±13.97s, 6.38±5.26, and 48.21±17.21 mL in the Kelman group and 11.39 ± 9.60s, 10.90 ± 9.25s, 4.04 ± 3.42, and 41.36 ± 12.70 mL in the balanced group, respectively. CONCLUSION: Torsional phacoemulsification performed with a balanced tip provided more effective lens removal with less total US time, torsional time, CDE, and BSS use, as well as similar changes in ECD with a Kelman tip in all cataract grades. This special designed phaco tip for torsional phacoemulsification provides an alternative phaco tip for many surgeons' preference with straight phaco tip.

    2015-01-01

    Degree correlation is an important topological property common to many real-world networks. In this paper, the statistical measures for characterizing the degree correlation in networks are investigated analytically. We give an exact proof of the consistency for the statistical measures, reveal the general linear relation in the degree correlation, which provide a simple and interesting perspective on the analysis of the degree correlation in complex networks. By using the general linear analysis, we investigate the perturbation of the degree correlation in complex networks caused by the addition of few nodes and the rich club. The results show that the assortativity of homogeneous networks such as the ER graphs is easily to be affected strongly by the simple structural changes, while it has only slight variation for heterogeneous networks with broad degree distribution such as the scale-free networks. Clearly, the homogeneous networks are more sensitive for the perturbation than the heterogeneous networks.

    2008-06-01

    The structural entropy is the entropy of the ensemble of uncorrelated networks with given degree sequence. Here we derive the most probable degree distribution emerging when we distribute stubs (or half-edges) randomly through the nodes of the network by keeping fixed the structural entropy. This degree distribution is found to decay as a Poisson distribution when the entropy is maximized and to have a power-law tail with an exponent → 2 when the entropy is minimized.

    This paper focuses on some 3-Engel groups. Suppose x and y are elements of a group G. The commutativity degree of a group is the probability that two elements in the group commute and is denoted by P(G). Meanwhile, the nth commutativity degree of a group G is the probability that for any pairs of x and y in G, xn and y commute. In this paper, the nth commutativity degree of some 3-Engel groups is determined.

    The community structure and motif-modular-network hierarchy are of great importance for understanding the relationship between structures and functions. We investigate the distribution of clique degrees, which are an extension of degree and can be used to measure the density of cliques in networks. Empirical studies indicate the extensive existence of power-law clique-degree distributions in various real networks, and the power-law exponent decreases with an increase of clique size.

The new program combines the expertise of four campuses and give students a broader choice of study options than any one campus can offer, while building an international professional experience. The initiative is funded jointly by the US Department of Education and the Education, Audiovisual and Culture Executive Agency (EACEA) of the European Community. Volcanology and geotechniques are global concerns: the volcanological community is fully globalized, while international consortia now deal with major geotechnical problems. Importantly, both fields require clear appreciation of specific local cultural, social and economical conditions. The new generation of researchers and professionals require international vision, but also the ability to understand local conditions. This masters specifically answers this need. This program will give students a language and cultural training in American English, French and Italian, as well as a wide course choice to meet each individual’s professional requirements. Students benefit from both research and professional approaches, acquiring a sound multidisciplinary profile for an excellent start to their careers. The trained INVOGE masters students will: meet a clear need for professionals/researchers with broad volcanology/geotechniques skills, and provide a workforce with international vision, but capable of addressing local projects. The project is innovative, combining international experience, strong multidisciplinary grounding and a broad subject range: students can choose among many possible advanced coursework and research combinations, and can have a broad choice of graduate advisors, field sites and

  19. Characterization of the degree of Musical non-Markovianity

    CERN Document Server

    Mannone, Maria

    2013-01-01

    Musical compositions could be characterized by a certain degree of memory, that takes into account repetitions and similarity of sequences of pitches, durations and intensities (the patterns). The higher the quantity of variations, the lower the degree of memory. This degree has never quantitatively been defined and measured. In physics, mathematical tools to quantify memory (defined as non-Markovianity) in quantum systems have been developed. The aim of this paper is to extend these mathematical tools to music, defining a general method to measure the degree of memory in musical compositions. Applications to some musical scores give results that agree with the expectations.

    Joshi, Rajesh Subhash; Muley, Sonal Jayant

    2017-01-01

    To evaluate the effective phaco time (EPT), cumulative dissipated energy (CDE) and nucleus emulsification time (NET) as phaco parameters with 0- and 30-degree phaco tip. This prospective, interventional and observational case series included 294 patients scheduled for cataract removal by phacoemulsification technique. Patients with nuclear cataracts of grade 4 and 5 nuclear opalescence of Lens Opacities Classification System III were included in the study. Patients were consecutively allocated to phaco chop technique with 0-degree (0-degree group, n=147) and combined bevel up and down position using 30-degree phaco tip (combined bevel up/down group, n=147). The 0-degree group had phacoemulsification with 0-degree phaco tip, while the 30-degree group had chopping of the nucleus with bevel down phaco tip and emulsification of nuclear fragments was accomplished with bevel up tip. EPT, CDE, NET and intraoperative complications were noted and compared between the groups using analysis of variance. Average EPT, CDE and NET were lower in the 30-degree group than in the 0-degree group. However, no statistically significant difference was found in EPT (P=0.0733), CDE (P=0.0663) and NET (P=0.0633) between the two groups. No serious intraoperative complications were noted. The anterior chamber was maintained throughout the procedure in both groups. No patients had wound burn and miosis during the procedure. None of the patients developed bullous keratopathy, uveitis and cystoid macular edema during the follow-up period. Combined bevel up and down 30-degree tip can yield effective hard nucleus phacoemulsification. Bevel down tip of 30-degree helps in effective chopping and bevel up tip assists in emulsification of the nuclear fragments. Although combined bevel up and down 30-degree tip can yield effective hard nucleus phacoemulsification, no statistically significant difference was found in EPT, CDE and NET between the two groups.

  8. Experiences with the Development of an Undergraduate Degree in Ecohydrology

    Science.gov (United States)

    Saito, L.; Walker, M.; Markee, N.

    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.

  6. A Geometric Approach for Multi-Degree Spline

    Institute of Scientific and Technical Information of China (English)

    Xin Li; Zhang-Jin Huang; Zhao Liu

    2012-01-01

    Multi-degree spline (MD-spline for short) is a generalization of B-spline which comprises of polynomial segments of various degrees.The present paper provides a new definition for MD-spline curves in a geometric intuitive way based on an efficient and simple evaluation algorithm.MD-spline curves maintain various desirable properties of B-spline curves,such as convex hull,local support and variation diminishing properties.They can also be refined exactly with knot insertion.The continuity between two adjacent segments with different degrees is at least C1 and that between two adjacent segments of same degrees d is Cd-1.Benefited by the exact refinement algorithm,we also provide several operators for MD-spline curves,such as converting each curve segment into Bézier form,an efficient merging algorithm and a new curve subdivision scheme which allows different degrees for each segment.

  7. The Degree of Symmetry of Certain Compact Smooth Manifolds Ⅱ

    Bin XU

    2007-01-01

    We give the sharp estimates for the degree of symmetry and the semi-simple degree of symmetry of certain compact fiber bundles with non-trivial four dimensional fibers in the sense of cobordism, by virtue of the rigidity theorem of harmonic maps due to Schoen and Yau (Topology, 18, 1979, 361-380). As a corollary of this estimate, we compute the degree of symmetry and the semi-simple degree of symmetry of CP2 × V, where V is a closed smooth manifold admitting a real analytic Riemannian metric of non-positive curvature. In addition, by the Albanese map, we obtain the sharp estimate of the degree of symmetry of a compact smooth manifold with some restrictions on its one dimensional cohomology.

  9. Patterning of the C. elegans 1 degrees vulval lineage by RAS and Wnt pathways.

    Science.gov (United States)

    Wang, M; Sternberg, P W

    2000-12-01

    In C. elegans, the descendants of the 1 degrees vulval precursor cell (VPC) establish a fixed spatial pattern of two different cell fates: E-F-F-E. The two inner granddaughters attach to the somatic gonadal anchor cell (AC) and generate four vulF cells, while the two outer granddaughters produce four vulE progeny. zmp-1::GFP, a molecular marker that distinguishes these two fates, is expressed in vulE cells, but not vulF cells. We demonstrate that a short-range AC signal is required to ensure that the pattern of vulE and vulF fates is properly established. In addition, signaling between the inner and outer 1 degrees VPC descendants, as well as intrinsic polarity of the 1 degrees VPC daughters, is involved in the asymmetric divisions of the 1 degrees VPC daughters and the proper orientation of the outcome. Finally, we provide evidence that RAS signaling is used during this new AC signaling event, while the Wnt receptor LIN-17 appears to mediate signaling between the inner and outer 1 degrees VPC descendants.

    Science.gov (United States)

    Muir, Fiona; Law, Susan

    2014-05-01

    Most doctors are involved in teaching to a greater or lesser degree and as such are required to keep their skills and knowledge up to date. Education for medical students has been moving up the political and professional agenda (GMC 2009, 2013). Currently, few Medical Schools offer a medical education intercalated degree programme. This study sets out to explore the students' experiences of a BMSc Teaching in Medicine Intercalated degree programme, offered by the School of Medicine Dundee, to help inform the value of an educational programme within an undergraduate medical curriculum. A small scale, exploratory case study was conducted with students who have completed the BMSc Teaching in Medicine Intercalated degree programme. A qualitative approach using three focus group interviews and questionnaire was carried out with 13 students within one University. The results show the value of the programme and the merit of experiential learning gained throughout the programme. Students enhanced their learning through collaboration and opportunities gained within and out with the Medical School gaining a better appreciation of the roles and responsibilities of staff roles and academic clinicians. The findings highlight the value of an intercalated teaching degree within a MBChB programme, its application and relevance to future practice and career development, for continuing personal and professional development and lifelong learning.

  11. Risk factors associated with forth-degree laceration during vaginal delivery

    N. Zafarghandi

    2006-08-01

    Full Text Available Background: To identify the risk factors of fourth-degree laceration during vaginal delivery. Methods: This is a retrospective, case control study. We reviewed 131802 records of vaginal deliveries within 14 years period from 1990 to 2004 in two obstetric center. Cases were 93 vaginal deliveries with fourth-degree laceration and 7 cases were delivered at home, control subjects were 200 vaginal deliveries without third- or fourth-degree lacerations and were identified with the use of random selection. We studied the effects of: maternal age, nationality, parity, gestational age, hour of delivery, birth attendants, episiotomy use and duration of second stage of labor, use of oxytocin, use of forceps or vaccum, Infant birth weight, presentation and postion of fetus, previous severe perineal injury, maternal medical illness and place of delivery. Results: We found 93 cases (%0.07 of documented fourth-degree laceration in 131802 deliveries Conclusion: This study identified several factors associated with fourth-degree laceration. Median episiotomy should be avoided. Nulliparity, fetal macrosomia and OP position are significant risk factors that require caution by birth attendants during delivery

  12. Control algorithm implementation for a redundant degree of freedom manipulator

    Science.gov (United States)

    Cohan, Steve

    1991-01-01

    This project's purpose is to develop and implement control algorithms for a kinematically redundant robotic manipulator. The manipulator is being developed concurrently by Odetics Inc., under internal research and development funding. This SBIR contract supports algorithm conception, development, and simulation, as well as software implementation and integration with the manipulator hardware. The Odetics Dexterous Manipulator is a lightweight, high strength, modular manipulator being developed for space and commercial applications. It has seven fully active degrees of freedom, is electrically powered, and is fully operational in 1 G. The manipulator consists of five self-contained modules. These modules join via simple quick-disconnect couplings and self-mating connectors which allow rapid assembly/disassembly for reconfiguration, transport, or servicing. Each joint incorporates a unique drive train design which provides zero backlash operation, is insensitive to wear, and is single fault tolerant to motor or servo amplifier failure. The sensing system is also designed to be single fault tolerant. Although the initial prototype is not space qualified, the design is well-suited to meeting space qualification requirements. The control algorithm design approach is to develop a hierarchical system with well defined access and interfaces at each level. The high level endpoint/configuration control algorithm transforms manipulator endpoint position/orientation commands to joint angle commands, providing task space motion. At the same time, the kinematic redundancy is resolved by controlling the configuration (pose) of the manipulator, using several different optimizing criteria. The center level of the hierarchy servos the joints to their commanded trajectories using both linear feedback and model-based nonlinear control techniques. The lowest control level uses sensed joint torque to close torque servo loops, with the goal of improving the manipulator dynamic behavior

    LINC-NIRVANA is the Fizeau beam combiner for the LBT, with the aim to retrieve the sensitivity of a 12m telescope and the spatial resolution of a 22.8m one. Despite being only one of the four wavefront sensors of a layer-oriented MCAO system, the GWS, which is retrieving the deformation introduced by the lower atmosphere, known to be the main aberration source, reveals a noticeable internal opto-mechanical complexity. The presence of 12 small devices used to select up to the same number of NGSs, with 3 optical components each, moving in a wide annular 2'-6' arcmin Field of View and sending the light to a common pupil re-imager, and the need to obtain and keep a very good super-imposition of the pupil images on the CCD camera, led to an overall alignment procedure in which more than a hundred of degrees of freedom have to be contemporary adjusted. The rotation of the entire WFS to compensate for the sky movement, moreover, introduces a further difficulty both in the alignment and in ensuring the required pupil superposition stability. A detailed description of the alignment procedure is presented here, together with the lessons learned managing the complexity of such a WFS, which led to considerations regarding future instruments, like a possible review of numerical versus optical co-add approach, above all if close to zero read-out noise detectors will be soon available. Nevertheless, the GWS AIV has been carried out and the system will be soon mounted at LBT to perform what is called the Pathfinder experiment, which consists in ground-layer correction, taking advantage of the Adaptive Secondary deformable Mirror.

  14. The Degree Semantics Parameter and cross-linguistic variation

    Directory of Open Access Journals (Sweden)

    M. Ryan Bochnak

    2015-03-01

    Full Text Available The standard degree analysis of gradability in English holds that the function of degree morphology, such as the comparative, measure phrases, and degree adverbs, is to bind a degree variable located in the lexical semantics of gradable predicates. In this paper, I investigate gradation structures in Washo (isolate/Hokan, and claim that this language systematically lacks degree morphology of this sort. I propose that this gap in the functional inventory of Washo stems from a parameter on whether languages are able to introduce degree variables into the logical form that can be bound by such operators, providing further cross-linguistic support for a similar proposal made by Beck et al. (2009 for Motu (Austronesian. Specifically, I argue that gradable predicates in Washo do not introduce a degree variable. Consequently, if we assume that gradable predicates in English are type ⟨d, ⟨e, t⟩⟩, then Washo and English must differ in their lexical semantics for gradable predicates. Alternatively, if we want to maintain lexical uniformity between the two languages (i.e., that gradable predicates in English don’t themselves introduce degrees, then we must place variation at the level of a grammatical mechanism that introduces degrees in English for degree operators to bind, but which is lacking in Washo. The results of this investigation thus inform questions about the nature of cross-linguistic variation, specifically the division of labor between variation in functional categories and the lexicon. http://dx.doi.org/10.3765/sp.8.6 BibTeX info

    2016-01-01

    Plausibility models are Kripke models that agents use to reason about knowledge and belief, both of themselves and of each other.

  16. Is That Graduate Degree Worth It? Comparing the Recruitment of Undergraduate and Graduate Degree Job Applicants

    Science.gov (United States)

    Richardson, R. M.

    2001-12-01

    One could argue from a business prospective that colleges and universities are not working hard enough to train students for life in the business and civic world, at either the undergraduate or graduate levels. What is it that employers are looking for in students? How different are the skills and attributes employers are looking for between undergraduate and graduate students? How unique are the geosciences in this respect? At the undergraduate level recruiters have spoken loud and clear about what they want. According to the dean of the business school here at the University of Arizona, recruiters at the undergraduate degree level in business base less than half of their hiring decision on specific content knowledge in the discipline, and correspondingly more than half on the so-called soft skills ... ability to apply knowledge in new situations, ability to think critically, ability to communicate with others in both written and oral forms, ability to work in teams, ability to work with a diverse set of employees and customers (especially, but not limited to, the global job market), etc. How true is this at the graduate level, where students have typically spent 4-6 years specializing in a discipline? Is there a set of fundamental knowledge that employers are looking for at the graduate level? Are the so-called soft skills correspondingly less important? I will present results from a survey of graduate programs and industry recruiters addressing these questions, and highlight the areas of overlap and difference between undergraduates and graduates looking for jobs. I will concentrate specifically on jobs in the oil industry and on both masters and Ph.D. programs.

    Obstetric injury is the commonest cause of anal incontinence. We report a case of anal incontinence as a result of severe chronic fourth-degree perineal tear secondary to birthing with complete disruption of the perineum. Secondary repair consisting of an anterior sphincter repair and levatorplasty in a poor resourced area rendered excellent immediate clinical result. The outcome of anterior sphincter repair following obstetric trauma is good but long-term follow-up is required because of the...

  1. Network controllability is determined by the density of low in-degree and out-degree nodes.

    Science.gov (United States)

    Menichetti, Giulia; Dall'Asta, Luca; Bianconi, Ginestra

    2014-08-15

    The problem of controllability of the dynamical state of a network is central in network theory and has wide applications ranging from network medicine to financial markets. The driver nodes of the network are the nodes that can bring the network to the desired dynamical state if an external signal is applied to them. Using the framework of structural controllability, here, we show that the density of nodes with in degree and out degree equal to one and two determines the number of driver nodes in the network. Moreover, we show that random networks with minimum in degree and out degree greater than two, are always fully controllable by an infinitesimal fraction of driver nodes, regardless of the other properties of the degree distribution. Finally, based on these results, we propose an algorithm to improve the controllability of networks.

    2011-01-01

    Vague集是Zadeh模糊集的一种推广形式,同样Vague集的包含度也是模糊集包含度的一种扩展.针对现有文献涉及到的Vague集的包含度只是属于[0,1]区间的一个模糊值的问题,根据Vague集理论的基本思想拓展了Vague集的包含度,提出一种新的Vague集的包含度定义,以体现Vague集的拓展意义.提出并验证了四类Vague集的包含度的计算公式,同时给出此Vague集包含度与模糊集包含度之间关系的定理.%Vague set is one of generalizations of Zadeh's fuzzy set, and Vague inclusion degree is also an extension of fuzzy inclusion degree.For the definition of Vague inclusion degree existed in present references is only a fuzzy value, this paper proposes a new definition of Vague inclusion degree to reflect the expansion meaning of the Vague set.This new Vague inclusion degree based on the notion of vague set extends the conception of Vague inclusion degree and fully expresses the advantage of Vague set. Four classes of Vague inclusion degree formulas are proposed and verified, a theorem about the relationship between Vague inclusion degree and fuzzy inclusion degree is given.

    2013-04-01

    Suppose x and y are elements of a group G. The commutativity degree of a group G is defined as the total number of pair (x, y) for which x and y commute divided by the total number of pair (x, y) which is possible. Moreover, the nth commutativity degree of a group G is the total number of pair (x, y) for which xn and y commute divided by the total number of (x, y) which is possible. In this research, all 2-Engel groups of order at most 25 are first determined. Then, the nth commutativity degree of those groups are computed.

    2013-07-01

    Full Text Available In this paper, we propose a novel algorithm to identify communities in complex networks based on the node belonging degree. First, we give the concept of the node belonging degree, and then determine whether a node belongs to a community or not according to the belonging degree of the node with respect to the community. The experiment results of three real-world networks: a network with three communities with 19 nodes, Zachary Karate Club and network of American college football teams show that the proposed algorithm has satisfactory community structure detection.  

  5. Nonlinearity degree of short-term heart rate variability signal

    BIAN Chunhua; NING Xinbao

    2004-01-01

    A nonlinear autoregressive (NAR) model is built to model the heartbeat interval time series and the optimum model degree is proposed to be taken to evaluate the nonlinearity degree of heart rate variability (HRV). A group of healthy persons are studied and the results indicate that this method can effectively get nonlinear information from short (6-7 min) heartbeat series and consequently reflect the degree of heart rate variability, which supplies convenience in clinical application. Finally, a comparison with the traditional time domain method shows that the NAR model method can reflect the complexity of the whole signal and lessen the influence of noise and instability in the signal.

    In this paper,we study a class of stochastic processes,called evolving network Markov chains,in evolving networks. Our approach is to transform the degree distribution problem of an evolving network to a corresponding problem of evolving network Markov chains.We investigate the evolving network Markov chains,thereby obtaining some exact formulas as well as a precise criterion for determining whether the steady degree distribution of the evolving network is a power-law or not.With this new method,we finally obtain a rigorous,exact and unified solution of the steady degree distribution of the evolving network.

    1992-01-01

    The purpose of this note is to provide some applications of Faltings' recent proof of S. Lang's conjecture to smooth plane curves. Let $C$ be a smooth plane curve defined by an equation of degree $d$ with integral coefficients. We show that for $d\\ge 7$, the curve $C$ has only finitely many points whose field of definition has degree $\\le d-2$ over $Q$, and that for $d\\ge 8$, all but finitely many points of $C$ whose field of definition has degree $\\le d-1$ over $Q$ arise as points of intersection of rational lines through rational points of $C$.

    Let $t$ be a rooted tree and $n_i(t)$ the number of nodes in $t$ having $i$ children. The degree sequence $(n_i(t),i\\geq 0)$ of $t$ satisfies $\\sum_{i\\ge 0} n_i(t)=1+\\sum_{i\\ge 0} in_i(t)=|t|$, where $|t|$ denotes the number of nodes in $t$. In this paper, we consider trees sampled uniformly among all trees having the same degree sequence $\\ds$; we write $`P_\\ds$ for the corresponding distribution. Let $\\ds(\\kappa)=(n_i(\\kappa),i\\geq 0)$ be a list of degree sequences indexed by $\\kappa$ corresponding to trees with size $\

  9. Subgroup s-commutativity degree of finite groups

    CERN Document Server

    Otera, Daniele Ettore

    2010-01-01

    In a recent contribution, Tarnauceanu has introduced the subgroup commutativity degree of a finite group, adapting to the context of the lattice theory some ideas and some techniques, which were known by the studies of Lescot on the commutativity degree. This new notion allows us to detect how a group is far from having all subgroups which are permutable. In the present paper we investigate a probability, which generalizes the subgroup commutativity degree, and find some numerical restrictions on groups which are rich in S-permutable subgroups in the sense of Kegel.

    2012-01-01

    It is well known that the set of possible degree sequences for a graph on $n$ vertices is the intersection of a lattice and a convex polytope. We show that the set of possible degree sequences for a $k$-uniform hypergraph on $n$ vertices is not the intersection of a lattice and a convex polytope for $k \\geq 3$ and $n \\geq k+13$. We also show an analogous nonconvexity result for the set of degree sequences of $k$-partite $k$-uniform hypergraphs and the generalized notion of $\\lambda$-balanced $k$-uniform hypergraphs.

    2012-01-01

    A semigroup is \\emph{nilpotent} of degree 3 if it has a zero, every product of 3 elements equals the zero, and some product of 2 elements is non-zero. It is part of the folklore of semigroup theory that almost all finite semigroups are nilpotent of degree 3. We give formulae for the number of nilpotent semigroups of degree 3 with $n\\in\\N$ elements up to equality, isomorphism, and isomorphism or anti-isomorphism. Likewise, we give formulae for the number of nilpotent commutative semigroups with $n$ elements up to equality and up to isomorphism.

  16. On Effective Degrees of Freedom in the Early Universe

    CERN Document Server

    Husdal, Lars

    2016-01-01

    We explore the effective degrees of freedom in the early Universe, from before the electroweak scale at a few femtoseconds after the Big Bang, until the last positrons disappeared a few minutes later. We first look at the established concepts of effective degrees of freedom for energy density, pressure and entropy density, and introduce effective degrees of freedom for number density as well. We discuss what happens with particle species as their temperature cools down from relativistic to semi- and non-relativistic temperatures, and then annihilates completely. This will affect the pressure as well as the entropy per particle. We also look at the transition from a quark-gluon plasma to a hadron gas. Using a list a known hadrons, we use a "cross-over" temperature of 214 MeV where the effective degrees of freedom for a quark-gluon plasma equals that of a hadron gas.

  17. Degree-based attacks and defense strategies in complex networks

    Yehezkel, Aviv; Cohen, Reuven

    2012-12-01

    We study the stability of random scale-free networks to degree-dependent attacks. We present analytical and numerical results to compute the critical fraction pc of nodes that need to be removed for destroying the network under this attack for different attack parameters. We study the effect of different defense strategies, based on the addition of a constant number of links on network robustness. We test defense strategies based on adding links to either low degree, middegree or high degree nodes. We find using analytical results and simulations that the middegree nodes defense strategy leads to the largest improvement to the network robustness against degree-based attacks. We also test these defense strategies on an internet autonomous systems map and obtain similar results.

The solutions are constructed from those of the scalar fractional diffusion equation. We analyze the interpolation between the standard diffusion and wave equations defined by the fractional derivatives.

    Parallel manipulators for the machine tool industry have been studied extensively for various industrial applications. However, limited useful workspace areas, the poor mobility, and design difficulties of more complex parallel manipulators have led to more interest in parallel manipulators with less than six degrees of freedom (DoFs). Several parallel mechanisms with various numbers and types of degrees of freedom are described in this paper, which can be used in parallel kinematics machines, motion simulators, and industrial robots.

  13. Are UK undergraduate Forensic Science degrees fit for purpose?

    Science.gov (United States)

    Welsh, Charles; Hannis, Marc

    2011-09-01

    In October 2009 Skills for Justice published the social research paper 'Fit for purpose?: Research into the provision of Forensic Science degree programmes in UK Higher Education Institutions.' The research engaged employers representing 95% of UK Forensic Science providers and 79% of UK universities offering Forensic Science or Crime Scene degree programmes. In addition to this, the research collected the views of 430 students studying these degrees. In 2008 there were approximately 9000 people working in the Forensic Science sector in the UK. The research found that the numbers of students studying Forensic Science or Crime Scene degrees in the UK have more than doubled since 2002-03, from 2191 in to 5664 in 2007-08. Over the same period there were twice as many females as males studying for these degrees. The research concluded that Forensic Science degree programmes offered by UK universities were of a good quality and they provided the student with a positive learning experience but the content was not relevant for Forensic Science employers. This echoed similar research by the former Government Department for Innovation, Universities and Skills on graduates from wider science, technology, engineering and mathematics degree programmes. The research also found that 75% of students studying Forensic Science or Crime Scene degrees expected to have a career in the Forensic Science sector, meaning that ensuring these courses are relevant for employers is a key challenge for universities. This paper reflects on the original research and discusses the implications in light of recent government policy. Copyright © 2011 Forensic Science Society. Published by Elsevier Ireland Ltd.

    2012-01-01

    We show that the degree of localization for the modes of a random laser (RL) is affected by the inter mode interaction that is controlled by shaping the spot of the pump laser. By experimentally investigating the spatial properties of the lasing emission we infer that strongly localized modes are activated in the low interacting regime while in the strongly interacting one extended modes are found lasing. Thus we demonstrate that the degree o localization may be finely tuned at the micrometer level.

    Full Text Available Rajesh Subhash Joshi, Sonal Jayant Muley Department of Ophthalmology, Vasantrao Naik Government Medical College, Yavatmal, Maharashtra, India Purpose: To evaluate the effective phaco time (EPT, cumulative dissipated energy (CDE and nucleus emulsification time (NET as phaco parameters with 0- and 30-degree phaco tip. Patients and methods: This prospective, interventional and observational case series included 294 patients scheduled for cataract removal by phacoemulsification technique. Patients with nuclear cataracts of grade 4 and 5 nuclear opalescence of Lens Opacities Classification System III were included in the study. Patients were consecutively allocated to phaco chop technique with 0-degree (0-degree group, n=147 and combined bevel up and down position using 30-degree phaco tip (combined bevel up/down group, n=147. The 0-degree group had phacoemulsification with 0-degree phaco tip, while the 30-degree group had chopping of the nucleus with bevel down phaco tip and emulsification of nuclear fragments was accomplished with bevel up tip. EPT, CDE, NET and intraoperative complications were noted and compared between the groups using analysis of variance. Results: Average EPT, CDE and NET were lower in the 30-degree group than in the 0-degree group. However, no statistically significant difference was found in EPT (P=0.0733, CDE (P=0.0663 and NET (P=0.0633 between the two groups. No serious intraoperative complications were noted. The anterior chamber was maintained throughout the procedure in both groups. No patients had wound burn and miosis during the procedure. None of the patients developed bullous keratopathy, uveitis and cystoid macular edema during the follow-up period. Conclusion: Combined bevel up and down 30-degree tip can yield effective hard nucleus phacoemulsification. Bevel down tip of 30-degree helps in effective chopping and bevel up tip assists in emulsification of the nuclear fragments. Although combined bevel up and down 30

    Williams, Oliver

    2014-01-01

    Scale-free networks, in which the distribution of the degrees obeys a power-law, are ubiquitous in the study of complex systems. One basic network property that relates to the structure of the links found is the degree assortativity, which is a measure of the correlation between the degrees of the nodes at the end of the links. Degree correlations are known to affect both the structure of a network and the dynamics of the processes supported thereon, including the resilience to damage, the spread of information and epidemics, and the efficiency of defence mechanisms. Nonetheless, while many studies focus on undirected scale-free networks, the interactions in real-world systems often have a directionality. Here, we investigate the dependence of the degree correlations on the power-law exponents in directed scale-free networks. To perform our study, we consider the problem of building directed networks with a prescribed degree distribution, providing a method for proper generation of power-law-distributed direc...

    We establish that the Magellanic Stream (MS) is some 40 degrees longer than previously known with certainty and that the entire MS and Leading Arm (LA) system is thus at least 200 degrees long. With the GBT, we conducted a ~200 square degree, 21-cm survey at the MS-tip to substantiate the continuity of the MS between the Hulsbosch & Wakker data and the MS-like emission reported by Braun & Thilker. Our survey, in combination with the Arecibo survey by Stanimirovic et al., shows that the MS gas is continuous in this region and that the MS is at least ~140 degrees long. We identify a new filament on the eastern side of the MS that significantly deviates from the equator of the MS coordinate system for more than ~45 degrees. Additionally, we find a previously unknown velocity inflection in the MS-tip near MS longitude L_MS=-120 degrees at which the velocity reaches a minimum and then starts to increase. We find that five compact high velocity clouds cataloged by de Heij et al. as well as Wright's Cloud ar...

    2017-09-23

    Postgraduate training, dual degrees, and board certifications are credentials viewed by academic pharmacy communities and professional organizations as positive assets for those seeking pharmacist jobs; however, a key question merits further investigation: do these views match employer expectations? The primary objective of this study was to identify the most common qualifications employers require as stated in job advertisements. Pharmacist job postings from the aggregate jobs website Indeed.com were evaluated for the 20 largest metropolitan areas in the United States. Search criteria included: pharmacist, full-time, and within a 50-mile radius of the metropolitan area. Positions were excluded if they were not pharmacist specific, did not require a pharmacy degree, were part-time, or were temporary. Required and preferred qualifications were collected in the following categories: practice type, experience needed, training, certification, and desired skills. Six hundred and eleven of 1356 postings met inclusion criteria. Positions were classified as community (113), health-system (264), industry (149), academia (9), or other (76). Four hundred and six (66.4%) required a minimum of a Bachelor's of Pharmacy degree, while 174 (28.4%) required a Doctor of Pharmacy degree. Experience was required for 467 positions (range of 6 months to 14 years). Postgraduate training was required for 73 positions (66 residency/7 fellowship). One job required a Master's degree, type unspecified. BPS certifications were required for 7 positions (1.1%) and preferred for 22 positions (3.6%). Certifications and skills most required by employers were verbal and written skills (248), Microsoft Office proficiency (93), immunization certifications (51), and Basic Life Support/Cardiopulmonary Resuscitation certifications (37). Postgraduate training, dual degrees, and board certification were not significant factors in the qualification criteria for the positions identified. The qualifications

    2009-05-01

    Full Text Available As part of a study on the expectations of benefit of higher education applicants, this article approaches the choice of a degree program according to the academic interest from the perspective of the rational analysis. Applicants who took the admissions test in two institutions were surveyed in order to carry out later statistical analysis with the purpose of finding a multivariate model. The obtained results showed that gender, work, and age were related to the applicants’ interest on certain academic degree program. The interest for a degree program tends to be unimportant in employed women’s choices, aged 20 years or older. Among applicants whose father considered higher education very important, the probability to consider one’s interest on the choice of a bachelor’s degree was higher for male applicants. The above information confirms the variation in rational calculations regarding social characteristics.

    Androgenic alopecia is a serious problem for a large proportion of the population, especially males, and causes them to seek medical help. Many methods have been described for treatment of androgenic alopesia. Among them are punch grafts, strip grafts, scalp grafts, scalp reductions, tissue expanders, and flap combinations, and hair transplantations with minigrafts and micrografts. The latter has become popular in the last two to three decades and has been investigated extensively. Improvements in hair replacement with minigrafts and micrografts may allow an ideal result with a nearly normal appearance. However, hair replacement with these grafts has important disadvantages. It requires a long operational time and only a limited number of grafts can be placed in one session. In this study, we investigated morphological structures of micrografts stored at 4 degrees C and those stored at -20 degrees C. We found that morphological structures of the grafts stored at 4 degrees C started to be impaired in the fifth day, but that the morphological structures of the grafts stored at -20 degrees C remained unaltered for 15 days. If this method is put into practice, the use of minigrafts and micrografts available will not only obviate the second graft harvesting, but also allow reconstruction of a large area in a short period of time.

  15. Structural system identification using degree of freedom-based reduction and hierarchical clustering algorithm

    A system identification method has been proposed to validate finite element models of complex structures using measured modal data. Finite element method is used for the system identification as well as the structural analysis. In perturbation methods, the perturbed system is expressed as a combination of the baseline structure and the related perturbations. The changes in dynamic responses are applied to determine the structural modifications so that the equilibrium may be satisfied in the perturbed system. In practical applications, the dynamic measurements are carried out on a limited number of accessible nodes and associated degrees of freedom. The equilibrium equation is, in principle, expressed in terms of the measured (master, primary) and unmeasured (slave, secondary) degrees of freedom. Only the specified degrees of freedom are included in the equation formulation for identification and the unspecified degrees of freedom are eliminated through the iterative improved reduction scheme. A large number of system parameters are included as the unknown variables in the system identification of large-scaled structures. The identification problem with large number of system parameters requires a large amount of computation time and resources. In the present study, a hierarchical clustering algorithm is applied to reduce the number of system parameters effectively. Numerical examples demonstrate that the proposed method greatly improves the accuracy and efficiency in the inverse problem of identification.

    Maria Angélica Tavares de Medeiros

    2013-10-01

    Full Text Available This essay aims to debate the minimum clock hours of instruction necessary for obtaining a bachelor's degree in nutrition considering the challenges to educate health professionals. Official documents on the minimum clock hours of instruction required by undergraduate nutrition programs were analyzed to investigate compliance with the curriculum guidelines for the area, the law that regulates the profession of dietitian, and the necessary education for the Sistema Único de Saúde (Unified Health Care System. Compared with other health programs, nutrition presented the smallest increase in the minimum clock hours of instruction required for the degree. The changes that occurred in the epidemiological, demographic, and nutritional profile of the population and scientific advances require specific nutrition actions. Since Sistema Único de Saúde focuses on comprehensiveness in the three levels of care, on humanization, and on health care, the theoretical and methodological concepts given in undergraduate programs need to be improved for the dietitians education to meet the Sistema Único de Saúde needs. Incorporation of the knowledge needed for working with food and nutritional phenomena, including its social and cultural dimensions, management of public policies, quantity cooking, and food and nutritional surveillance requires a higher minimum clock hours of instruction. In conclusion, dietitians need a minimum clock hours of instruction of 4,000 to acquire a proper education, integrate into the university life, and coordinate interdisciplinary experiences of the triad teaching/research/extension.

    2008-01-01

    The thermal requirements for development of Dermanyssus gallinae were studied under laboratory conditions at 15, 20, 25, 30 and 35 degrees C, a 12h photoperiod and 60-85% RH. The thermal requirements for D. gallinae were as follows. Preoviposition: base temperature 3.4 degrees C, thermal constant (k) 562.85 degree-hours, determination coefficient (R(2)) 0.59, regression equation: Y= -0.006035 + 0.001777x. Egg: base temperature 10.60 degrees C, thermal constant (k) 689.65 degree-hours, determination coefficient (R(2)) 0.94, regression equation: Y= -0.015367 + 0.001450x. Larva: base temperature 9.82 degrees C, thermal constant (k) 464.91 degree-hours, determination coefficient (R(2)) 0.87, regression equation: Y= -0.021123 + 0.002151x. Protonymph: base temperature 10.17 degrees C, thermal constant (k) 504.49 degree-hours, determination coefficient (R(2)) 0.90, regression equation: Y= -0.020152 + 0.001982x. Deutonymph: base temperature 11.80 degrees C, thermal constant (k) 501.11 degree-hours, determination coefficient (R(2)) 0.99, regression equation: Y= -0.023555 + 0.001996x. The results obtained showed that 15 to 42 generations of Dermanyssus gallinae may occur during the year in the State of São Paulo, as estimated based on isotherm charts. Dermanyssus gallinae may develop continually in the State of São Paulo, with a population decrease in the winter. There were differences between the developmental stages of D. gallinae in relation to thermal requirements.

    In model-based development, the development effort is centered around a formal description of the proposed software system the model. This model is derived from some high-level requirements describing the expected behavior of the software. For validation and verification purposes, this model can then be subjected to various types of analysis, for example, completeness and consistency analysis [6], model checking [3], theorem proving [1], and test-case generation [4, 7]. This development paradigm is making rapid inroads in certain industries, e.g., automotive, avionics, space applications, and medical technology. This shift towards model-based development naturally leads to changes in the verification and validation (V&V) process. The model validation problem determining that the model accurately captures the customer's high-level requirements has received little attention and the sufficiency of the validation activities has been largely determined through ad-hoc methods. Since the model serves as the central artifact, its correctness with respect to the users needs is absolutely crucial. In our investigation, we attempt to answer the following two questions with respect to validation (1) Are the requirements sufficiently defined for the system? and (2) How well does the model implement the behaviors specified by the requirements? The second question can be addressed using formal verification. Nevertheless, the size and complexity of many industrial systems make formal verification infeasible even if we have a formal model and formalized requirements. Thus, presently, there is no objective way of answering these two questions. To this end, we propose an approach based on testing that, when given a set of formal requirements, explores the relationship between requirements-based structural test-adequacy coverage and model-based structural test-adequacy coverage. The proposed technique uses requirements coverage metrics defined in [9] on formal high-level software

    Full Text Available Controlling complex network is an essential problem in network science and engineering. Recent advances indicate that the controllability of complex network is dependent on the network's topology. Liu and Barabási, et.al speculated that the degree distribution was one of the most important factors affecting controllability for arbitrary complex directed network with random link weights. In this paper, we analysed the effect of degree distribution to the controllability for the deterministic networks with unweighted and undirected. We introduce a class of deterministic networks with identical degree sequence, called (x,y-flower. We analysed controllability of the two deterministic networks ((1, 3-flower and (2, 2-flower by exact controllability theory in detail and give accurate results of the minimum number of driver nodes for the two networks. In simulation, we compare the controllability of (x,y-flower networks. Our results show that the family of (x,y-flower networks have the same degree sequence, but their controllability is totally different. So the degree distribution itself is not sufficient to characterize the controllability of deterministic networks with unweighted and undirected.

    Chitosan is often characterized by its average degree of acetylation. To increase chitosan's use in various industries, a more thorough characterization is necessary as the acetylation of chitosan affects properties such as dissolution and mechanical properties of chitosan films. Despite the poor solubility of chitosan, free solution capillary electrophoresis (CE) allows a robust separation of chitosan by the degree of acetylation. The distribution of degrees of acetylation of various chitosan samples was characterized through their distributions of electrophoretic mobilities. These distributions can be obtained easily and with high precision. The heterogeneity of the chitosan chains in terms of acetylation was characterized through the dispersity of the electrophoretic mobility distributions obtained. The relationship between the number-average degree of acetylation obtained by solid-state NMR spectroscopy and the weight-average electrophoretic mobilities was established. The distribution of degrees of acetylation was determined using capillary electrophoresis in the critical conditions (CE-CC). Copyright © 2016 Elsevier B.V. All rights reserved.

    2016-09-01

    The study of interdependent networks has become a new research focus in recent years. We focus on one fundamental property of interdependent networks: vulnerability. Previous studies mainly focused on the impact of topological properties upon interdependent networks under random attacks, the effect of degree heterogeneity on structural vulnerability of interdependent networks under intentional attacks, however, is still unexplored. In order to deeply understand the role of degree distribution and in particular degree heterogeneity, we construct an interdependent system model which consists of two networks whose extent of degree heterogeneity can be controlled simultaneously by a tuning parameter. Meanwhile, a new quantity, which can better measure the performance of interdependent networks after attack, is proposed. Numerical simulation results demonstrate that degree heterogeneity can significantly increase the vulnerability of both single and interdependent networks. Moreover, it is found that interdependent links between two networks make the entire system much more fragile to attacks. Enhancing coupling strength between networks can greatly increase the fragility of both networks against targeted attacks, which is most evident under the case of max-max assortative coupling. Current results can help to deepen the understanding of structural complexity of complex real-world systems.

    Designers search for N-nodes peer-to-peer networks that can have O(1) out-degree with O(log2 N) average distance.Peer-to-peer schemes based on de Bruijn graphs are found to meet this requirement. By defining average load to evaluate the traffic load in a network, we show that in order to decrease the average load, the average distance of a network should decrease while the out-degree should increase.Especially, given out-degree k and N nodes, peer-to-peer schemes based on de Bruijn graphs have lower average load than other existing systems. The out-degree k of de Bruijn graphs should not be O(1) but should satisfy a lower bound described by an inequality kk≥ N2, to ensure that the average load in peer-to-peer schemes based on de Bruijn graphs will not exceed that in Chord system.

Focusing on Germany, we analyze labor market entries of individuals eligible...... training degrees, and with higher prestige (but similar earnings) than further vocational degrees. However, bachelor’s degrees from universities are also related to higher risks of unemployment or fixed-term employment. Universities of applied sciences, which combine academic and practical training, offer...... both high earnings and prestigious jobs as well as low risks of unemployment or fixed-term employment at the bachelor’s and the master’s level. Overall, ‘general’ academic education provides advantages over vocational education, despite these structural changes. Variations by field of study...

    With respect to the decision making problems where a lot of fuzzy and grey information always exists in the real-life deci-sion making information system, it is difficult for such uncertainty methods as fuzzy mathematics, probability, and interval numbers to deal with. To this end, based on the thought and method of grey numbers, grey degrees and interval numbers, the concept of dominance grey degree is defined. And then a method of rank-ing interval grey numbers based on the dominance grey degree is proposed. After discussing the relevant properties, the paper final y uses an example to demonstrate the effectiveness and ap-plicability of the model. The result shows that the proposed model can more accurately describe uncertainty decision making prob-lems, and realize the total ordering process for multiple-attribute decision-making problems.

    2009-01-01

    We study a multi-source Gaussian relay network consisting of $K$ source--destination pairs having $K$ unicast sessions. We assume $M$ layers of relays between the sources and the destinations. We find achievable degrees of freedom of the network. Our schemes are based on interference alignment at the transmitters and symbol extension and opportunistic interference cancellation at the relays. For $K$-$L$-$K$ networks, i.e., 2-hop network with $L$ relays, we show $\\min\\{K,K/2+L/(2(K-1))\\}$ degrees of freedom are achievable. For $K$-hop networks with $K$ relays in each layer, we show the full $K$ degrees of freedom are achievable provided that $K$ is even and the channel distribution satisfies a certain symmetry.

    2015-01-01

    In this article we analyze the global flow of migrants from 206 source countries to 145 destination countries (2006-2010) and focus on the differences in the migration network pattern between destination and source counters as represented by its degree and weight distribution. Degree represents the connectivity of a country to the global migration network, and plays an important role in defining migration processes and characteristics. Global analysis of migration degree distribution offers a strong potential contribution to understanding of migration as a global phenomenon. In regard to immigration, we found that it is possible to classify destination countries into three classes: global migration hubs with high connectivity and high migration rate; local migration hubs with low connectivity and high migration rate; and local migration hubs with opposite strategy of high connectivity and low migration rate. The different migration strategies of destination countries are emerging from similar and homogenies p...

    This article explains how an undergraduate programme is devised and validated. Since 1993, all courses in radiography have been of graduate level with radiography education being based in higher educational institutions. Before a new degree is implemented a review of the existing programme is undertaken. The proposed degree philosophy and learning outcomes need to be determined before the content; its mode of delivery and assessment are developed. Input from stakeholders (such as clinical colleagues) is necessary as well as adherence to policies and strategies for radiography education. Throughout the development process compliance with policy, both national and local, is critical. All radiography programmes have to be validated/accredited by representatives from national organisations--such as The Society and College of Radiographers (SCoR). These representatives scrutinise the proposed degree course documentation; often they may also inspect the clinical and university facilities in which the education and training will take place.

  11. Fuzzy MCDM Based on Fuzzy Relational Degree Analysis

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    This paper presents a new fuzzy multiple criteria (both qualitative and quantitative) decision-making (MCDM) method based on fuzzy relational degree analysis. The concepts of fuzzy set theory are used to construct a weighted suitability decision matrix to evaluate the weighted suitability of different alternatives versus various criteria. The positive ideal solution and negative ideal solution are then obtained by using a method of ranking fuzzy numbers, and the fuzzy relational degrees of different alternatives versus positive ideal solution and negative ideal solution are calculated by using the proposed arithmetic. Finally, the relative relational degrees of various alternatives versus positive ideal solution are ranked to determine the best alternative. A numerical example is provided to illustrate the proposed method at the end of this paper.

  12. Spatial Degrees of Freedom in Everett Quantum Mechanics

    Stapp claims that, when spatial degrees of freedom are taken into account, Everett quantum mechanics is ambiguous due to a "core basis problem." To examine this claim I generalize the ideal measurement model to include translational degrees of freedom for both the measured system and the measuring apparatus. Analysis of this generalized model using the Everett interpretation in the Heisenberg picture shows that it makes unambiguous predictions for the possible results of measurements and their respective probabilities. The presence of translational degrees of freedom for the measuring apparatus affects the probabilities of measurement outcomes in the same way that a mixed state for the measured system would. Examination of measurement scenarios involving several observers illustrates the consistency of the model with perceived spatial localization of the measuring apparatus, with intersubjective agreement as to the results of measurement, and with the idea of measurement as "state preparation."

  13. Introducing Modified Degree 4 Chordal Rings with Two Chord Lengths

    Pedersen, Jens Myrup

    2007-01-01

    In this paper an analysis of modified degree 4 Chordal Rings with two chord lengths named CHRm is presented and compared to similar topologies: Chordal Rings, N2R and modified N2R. Formulas for approximating diameters and average path lengths are provided and verified, and it is shown...... that the distances in CHRm are significantly smaller than in traditional Chordal Rings and N2R, and also smaller than modified N2R for topologies with up to 1500 nodes. Despite the proposed CHRm being of degree 4, and the modified N2R of degree 3, CHRm may be better suited for the optical level of fiber rings, due...... to its easy mapping onto the ring. It seems to be superior also to the traditional Chordal Rings, but it is not node symmetric....

    2007-01-01

    Ten indicators were selected in the present paper concerns current status of soil erosion and its driving forces. Synthesized evaluation model on danger degree of soil erosion (DDSE) was built and estimation on DDSE in Rikaze was carried out by analytical hierarchy process (AHP). This evaluation model selected indicators scientifically and reasonably, which are easy to be caught, and played well in application. Results showed that a light erosion danger degree exists in Nanmulin, Xietongmen and Angren; Dingri, Sajia, Saga, Zhongba; Nielamu, Gangba, Kangma and Rikaze County share a moderate danger degree, while other counties own severe erosion, especially Dingjie and Lazi County. Ecological environment in Rikaze is frangible. Therefore, eco-restoration and corresponding countermeasures are urgently needed in this region to guarantee a regional eco-environment healthy.

  15. Perturbative Degrees of Freedom in Loop Quantum Gravity: Anisotropies

    Bojowald, M; Morales-Tecotl, H A; Bojowald, Martin; Hernandez, Hector H.; Morales-Tecotl, Hugo A

    2006-01-01

    The relation between an isotropic and an anisotropic model in loop quantum cosmology is discussed in detail, comparing the strict symmetry reduction with a perturbative implementation of symmetry. While the latter cannot be done in a canonical manner, it allows to consider the dynamics including the role of small non-symmetric degrees of freedom for the symmetric evolution. This serves as a model for the general situation of perturbative degrees of freedom in a background independent quantization such as loop quantum gravity, and for the more complicated addition of perturbative inhomogeneities. While being crucial for cosmological phenomenology, it is shown that perturbative non-symmetric degrees of freedom do not allow definitive conclusions for the singularity issue and in such a situation could even lead to wrong claims.

  16. On regulators with a prescribed degree of stability. M.S. Thesis

    Ng, P. T. P.

    1981-01-01

    Several important aspects of the Regulator with a Prescribed Degree of Stability (RPDS) methodology and its applications are considered. The solution of the time varying RPDS problem as well as the characterization of RPDS closed loop eigenstructure properties are obtained. Based on the asymptotic behavior of RPDS root loci, a one step algorithm for designing Regulators with Prescribed Damping Ratio (RPDR) is developed. The robustness properties of RPDS are characterized in terms of the properties of the return difference and the inverse return difference matrices for the RPDS state feedback loop. This class of regulators is found to possess excellent multiloop margins with respect to stability and degree of stability properties. The ability of RPDS design to tolerate changing operating conditions and unmodelled dynamics are illustrated with a multiterminal dc/ac power system example. The output feedback realization of RPDS requires the use of Linear Quadratic Gaussian (LQG) methodology.

  17. Removing External Degrees of Freedom from Transition-State Search Methods using Quaternions

    2015-01-01

    In finite systems, such as nanoparticles and gas-phase molecules, calculations of minimum energy paths (MEPs) connecting initial and final states of transitions as well as searches for saddle points are complicated by the presence of external degrees of freedom, such as overall translation and rotation. A method based on quaternion algebra for removing the external degrees of freedom is described here and applied in calculations using two commonly used methods: the nudged elastic band (NEB) method for MEPs and the DIMER method for finding the minimum mode in minimum mode following searches of first-order saddle points. With the quaternion approach, fewer images in the NEB are needed to represent MEPs accurately. In both NEB and DIMER calculations of finite systems, the number of iterations required to reach convergence is significantly reduced. The algorithms have been implemented in the Atomic Simulation Environment (ASE) open source software.

    2009-01-01

    Many applications in network analysis require efficient algorithms to sample uniformly at random from the set of all graphs with a prescribed degree sequence. We solve this long-standing open problem for both the directed and undirected case using a Markov chain based approach. By spectral analysis we prove that our Markov chains are rapidly mixing, i.e., we can determine a random realization in polynomial time. Previous solutions to these sampling problems have either been restricted to special classes of degree sequences or only led to approximately uniform sampling. For the case of directed graphs, we also explain in this paper why a popular switching algorithm fails in general to sample uniformly at random but characterize under which efficiently checkable conditions it will provable succeed in polynomial time. Finally, we point out some interesting consequences for network analysis.

    Full Text Available As neonatal resuscitation critically depends upon lung aeration at birth, knowledge of the progression of this process is required to guide ongoing care. We investigated whether expired CO2 (ECO2 levels indicate the degree of lung aeration immediately after birth in two animal models and in preterm infants. Lambs were delivered by caesarean section and ventilated from birth. In lambs, ECO2 levels were significantly (p10 mmHg 28 (median (21-36 seconds before the heart rate increased above 100 beats per minute. These data demonstrate that ECO2 levels can indicate the relative degree of lung aeration after birth and can be used to clinically assess ventilation in the immediate newborn period.

  20. Commentary: collaboration in dual degree programs contributes something new to both fields.

    Science.gov (United States)

    Boumil, Marcia M

    2014-05-01

    Dual degree programs in public health and law have blossomed in the United States and beyond. They are traditionally promoted on the premise that public health efforts often require legal authority to legitimize and implement their goals and objectives, and that participation of lawyers safeguards respect for individual rights, privacy, and autonomy against governmental intrusion in furtherance of public health objectives. Thus, lawyers who understand public health are far more valuable in promoting population health than traditional constitutional and administrative law practitioners without such understanding. On the public health side, epidemiologists and other practitioners trained in the law ensure that reliable data inform public policy. In the classroom, we have found that dual degree students enrich the educational experience in both fields, broadening understanding and creating conversations that transcend law or public health alone.

    2014-01-01

    We surveyed physicians who obtained their medical degree with a thesis in 2011 from the seven medical schools in Lima to know the characteristics of the degree by thesis process, as well as participants’ motivations and perceptions of that process. We included 98 students who did a thesis (87% of total); 99% conducted observational thesis, 30% did so in groups of three. The main motivation was that it was good for their curriculum vitae (94%). At the university where the thesis is compulsory, the process began with the choice of topic and adviser. Perceived “greatest” and “least” difficulty in the process was the completion of administrative procedures (53%) and selection of their advisor (11%), respectively. Administrative timeliness and processes should be reviewed so as not to impede the completion of thesis, since the new University Act requires the completion of a thesis to graduate.

    1992-01-01

    The European Space Agency (ESA) has decided to extend its test facilities at the European Space and Technology Center (ESTEC) at Noordwijk, The Netherlands, by implementing a 6-degree-of-freedom hydraulic shaker. This shaker will permit vibration testing of large payloads in the frequency range from 0.1 Hz to 100 Hz. Conventional single axis sine and random vibration modes can be applied without the need for a configuration change of the test set-up for vertical and lateral excitations. Transients occurring during launch and/or landing of space vehicles can be accurately simulated in 6-degrees-of-freedom. The performance requirements of the shaker are outlined and the results of the various trade-offs, which are investigated during the initial phase of the design and engineering program are provided. Finally, the resulting baseline concept and the anticipated implementation plan of the new test facility are presented.

  3. Additional degrees of freedom associated with position measurements in non-commutative quantum mechanics

    Rohwer, CM

    2012-01-01

    In this thesis we shall demonstrate that a measurement of position alone in non-commutative space cannot yield complete information about the quantum state of a particle. Indeed, the formalism used entails a description that is non-local in that it requires all orders of positional derivatives through the star product that is used ubiquitously to map operator multiplication onto function multiplication in non-commutative systems. It will be shown that there exist several equivalent local descriptions, which are arrived at via the introduction of additional degrees of freedom. Consequently non-commutative quantum mechanical position measurements necessarily confront us with some additional structure which is necessary to specify quantum states completely. The remainder of the thesis, will involve investigations into the physical interpretation of these additional degrees of freedom. For one particular local formulation, the corresponding classical theory will be used to demonstrate that the concept of extended...

    2010-11-01

    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.

  5. Enhanced versatility of fluid control in centrifugal microfluidic platforms using two degrees of freedom.

    2016-04-01

    Centrifugal microfluidic platforms have significant potential in commercial applications because of their operational flexibility and minimal external infrastructure requirements. However, the dynamic and real-time control of fluid flow within traditional centrifugal microfluidic platforms is problematic. To address this significant limitation, we propose a two degrees of freedom platform, in which a digital servo is located at each end of an arm driven by a motor. This allows for reversible inward pumping between multiple chambers with perfect efficiency. Furthermore, the addition of a second degree of freedom allows position-based pressure controlled burst valves to be accessed and operated in an independent fashion. To demonstrate the efficacy of this technical innovation, we show rapid and configurable flow switching between three target chambers within a centrifugal microfluidic device.

  6. Development of a medical academic degree system in China

    2014-01-01

    Full Text Available Context: The Chinese government launched a comprehensive healthcare reform to tackle challenges to health equities. Medical education will become the key for successful healthcare reform. Purpose: We describe the current status of the Chinese medical degree system and its evolution over the last 80 years. Content: Progress has been uneven, historically punctuated most dramatically by the Cultural Revolution. There is a great regional disparity. Doctors with limited tertiary education may be licensed to practice, whereas medical graduates with advanced doctorates may have limited clinical skills. There are undefined relationships between competing tertiary training streams, the academic professional degree, and the clinical residency training programme (RTP. The perceived quality of training in both streams varies widely across China. As the degrees of master or doctor of academic medicine is seen as instrumental in career advancement, including employability in urban hospitals, attainment of this degree is sought after, yet is often unrelated to a role in health care, or is seen as superior to clinical experience. Meanwhile, the practical experience gained in some prestigious academic institutions is deprecated by the RTP and must be repeated before accreditation for clinical practice. This complexity is confusing both for students seeking the most appropriate training, and also for clinics, hospitals and universities seeking to recruit the most appropriate applicants. Conclusion: The future education reforms might include: 1 a domestic system of ‘credits’ that gives weight to quality clinical experience vs. academic publications in career advancement, enhanced harmonisation between the competing streams of the professional degree and the RTP, and promotion of mobility of staff between areas of excellence and areas of need; 2 International – a mutual professional and academic recognition between China and other countries by reference to

    2011-04-01

    Full Text Available Purpose: This paper has a double purpose. First, to analyze the competencies and skills proposed as ideals for an Industrial Engineering degree and identify them in the current study plans implemented in Spanish universities. Second, to check the fit between competencies and skills described in Spanish Industrial Engineering degrees and a real business environment.Design/methodology/approach: We searched information from universities through the web www.universia.es and obtained the list of all Spanish Universities, which have been filtered one by one according to their studies about Industrial Engineering degree. In addition, to compare competencies with real business world we have used results provided from the web analysis and from a previous paper in which a qualitative methodology called grounded theory was used.Findings: On one hand, we have analyzed and identified the competencies and skills proposed as ideals for an Industrial Engineering degree in the current study plans implemented in Spanish universities: competencies as multidisciplinariety and R&D are considered in all the universities, but commercial or environment are not so popular. On the other hand we have checked the fit between competencies and skills described in Spanish Industrial Engineering degrees and a real business environment. As a result, competencies as rotation, experience, company vision and corporative strategy are in all the analyzed study plans, but competencies as shared vision, free access to information and involvement of managers do not appear in new degrees, but they are required in real business.Research limitations/implications: About the origin of information, we use official web sites belonging to Spanish public and some private universities, and corresponding schools. Some universities have not updated the information about degrees in Industrial Engineering, and they still have old plans information. Moreover, the comparison we can make between the

    Parameters k-distance and k-diameter are extension of the distance and the diameter in graph theory. In this paper, the k-distance dk (x,y) between the any vertices x andy is first obtained in a connected circulant graph G with order n (n is even) and degree 3 by removing some vertices from the neighbour set of the x. Then, the k-diameters of the connected circulant graphs with order n and degree 3 are given by using the k-diameter dk (x, y).

    2009-01-01

    The wavelength assignment with multiple multicast requests in fixed routing WDM network is studied. A new multicast dynamic wavelength assignment algorithm is presented based on matching degree. First, the wavelength matching degree between available wavelengths and multicast routing trees is introduced into the algorithm. Then, the wavelength assign-ment is translated into the maximum weight matching in bipartite graph, and this matching problem is solved by using an extended Kuhn-Munkres algorithm. The simulation results prove that the overall optimal wavelength assignment scheme is obtained in polynomial time. At the same time, the proposed algorithm can reduce the connecting blocking probability and improve the system resource utilization.

    2002-01-01

    We construct the Hamiltonian of the super five brane in terms of its physical degrees of freedom. It does not depend on the inverse of the induced metric. Consequently, some singular configurations are physically admissible, implying an interpretation of the theory as a multiparticle one. The symmetries of the theory are analyzed from the canonical point of view in terms of the first and second class constraints. In particular it is shown how the chiral sector may be canonically reduced to its physical degrees of freedom.

    We show that all the spatiotemporal degrees of freedom available in a complex medium can be harnessed and converted into spatial ones. This is demonstrated experimentally through an instantaneous spatial inversion, using broadband ultrasonic waves in a multiple scattering sample. We show theoretically that the inversion convergence is governed by the total number of degrees of freedom available in the medium for a fixed bandwidth and demonstrate experimentally its use for complex media investigation. We believe our approach has potential in sensing, imagery, focusing, and telecommunication.

  20. Physicians with MBA degrees: change agents for healthcare improvement.

    Science.gov (United States)

    Lazarus, Arthur

    2010-01-01

    Increasingly, physicians gravitating toward the fields of quality improvement and healthcare management are seeking MBA degrees to supplement their medical training. Approximately half of all U.S. medical schools offer combined MD-MBA degrees, and numerous executive MBA programs exist for physicians in practice. Physicians who enter management are considered change agents for healthcare improvement, yet they receive little support and encouragement from their medical teachers and practicing colleagues. This situation can be rectified by placing greater value on the role of business-trained physicians and subsidizing their tuition for business school.
