    2012-02-01

    Local field potentials (LFP), the low-frequency part of extracellular electrical recordings, are a measure of the neural activity reflecting dendritic processing of synaptic inputs to neuronal populations. To localize synaptic dynamics, it is convenient, whenever possible, to estimate the density of transmembrane current sources (CSD) generating the LFP. In this work, we propose a new framework, the kernel current source density method (kCSD), for nonparametric estimation of CSD from LFP recorded from arbitrarily distributed electrodes using kernel methods. We test specific implementations of this framework on model data measured with one-, two-, and three-dimensional multielectrode setups. We compare these methods with the traditional approach through numerical approximation of the Laplacian and with the recently developed inverse current source density methods (iCSD). We show that iCSD is a special case of kCSD. The proposed method opens up new experimental possibilities for CSD analysis from existing or new recordings on arbitrarily distributed electrodes (not necessarily on a grid), which can be obtained in extracellular recordings of single unit activity with multiple electrodes.

    Adequate physical fitness is essential for successful military service. Military organizations worldwide therefore make continuous efforts to improve their army's physical training (PT) programs. To investigate the effect of the training methods and the qualification of PT instructors on the development of recruits' physical fitness, the present study compared the outcomes of 2 training groups. Both study groups participated in approximately 145 minutes per week of PT. The control group executed the standard army PT prepared and supervised by army PT instructors. Content of the PT in the intervention group was similar to that of the control group, but their training sessions' methods were different. Their training sessions were organized, prepared, and delivered by more and better-qualified supervisors (tertiary-educated physical education teachers). After 10 weeks of training, the participants of the intervention group experienced a significantly greater physical fitness improvement than those of the control group (positive change in endurance 32 and 17%, balance 30 and 21%, and core strength 74 and 45%, respectively). In both groups, the recruits with the lowest initial fitness levels significantly increased their performance. In the intervention group, but not the control, one-third of the recruits with the highest initial fitness levels were able to further improve their general fitness performance. This study demonstrates that the training methods and quality of instruction during PT sessions are relevant for recruits' fitness development in basic military training.

    We evaluated preventive cardiology education in United States cardiology fellowship programs and their adherence to Core Cardiovascular Training Symposium training guidelines, which recommend 1 month of training, faculty with expertise, and clinical experience in cardiac rehabilitation, lipid disorder management, and diabetes management as a part of the prevention curricula. We sent an anonymous survey to United States cardiology program directors and their chief fellow. The survey assessed the program curricula, rotation structure, faculty expertise, obstacles, and recommended improvements. The results revealed that 24% of surveyed programs met the Core Cardiovascular Training Symposium guidelines with a dedicated 1-month rotation in preventive cardiology, 24% had no formalized training in preventive cardiology, and 30% had no faculty with expertise in preventive cardiology, which correlated with fewer rotations in prevention than those with specialized faculty (p = 0.009). Fellows rotated though the following experiences (% of programs): cardiac rehabilitation, 71%; lipid management, 37%; hypertension, 15%; diabetes, 7%; weight management/obesity, 6%; cardiac nutrition, 6%; and smoking cessation, 5%. The program directors cited "lack of time" as the greatest obstacle to providing preventive cardiology training and the chief fellows reported "lack of a developed curriculum" (p = 0.01). The most recommended improvement was for the American College of Cardiology to develop a web-based curriculum/module. In conclusion, most surveyed United States cardiology training programs currently do not adhere to basic preventive cardiovascular medicine Core Cardiovascular Training Symposium recommendations. Additional attention to developing curricular content and structure, including the creation of an American College of Cardiology on-line knowledge module might improve fellowship training in preventive cardiology.

    Full Text Available Evidence based medicine (EBM is the conscientious, explicit and judicious use of current best evidence in making decisions about the care of individual patients. It is estimated that only 15% of medical interventions is evidence-based. Increasing demand, new technological developments, malpractice legislations, a very speed increase in knowledge and knowledge sources push the physicians forward for EBM, but at the same time increase load of physicians by giving them the responsibility to improve their skills. Clinical maneuvers are needed more, as the number of clinical trials and observational studies increase. However, many of the physicians, who are in front row of patient care do not use this increasing evidence. There are several examples related to different training methods in order to improve skills of physicians for evidence based practice. There are many training methods to improve EBM skills and these trainings might be given during medical school, during residency or as continuous trainings to the actual practitioners in the field. It is important to discuss these different training methods in our country as well and encourage dissemination of feasible and effective methods. [TAF Prev Med Bull 2010; 9(3.000: 245-254

    The aims of this study were to determine the validity of the session rating of perceived exertion (session-RPE) method by comparing 3 different scales of perceived exertion with common measures of training load (TL). A secondary aim was to verify the relationship between TLs, fitness, and performance in Sprint Kayak athletes. After laboratory assessment of maximal oxygen uptake (V[Combining Dot Above]O2peak) and lactate threshold, the athletes performed on water time trials over 200 and 1,000 m. Training load was quantified for external (distance and speed) and internal (session-RPE: 6-20, category ratio [CR]-10 and CR-100 scales, training impulse [TRIMP], and individual TRIMP). Ten (6 male, 4 female) well-trained junior Sprint Kayak athletes (age 17.1 ± 1.2 years; V[Combining Dot Above]O2peak 4.2 ± 0.7 L·min) were monitored over a 7-week period. There were large-to-very large within-individual correlations between the session distance and the various heart rate (HR) and RPE-based methods for quantifying TL (0.58-0.91). Correlations between the mean session speed and various HR- and RPE-based methods for quantifying TL were small to large (0.12-0.50). The within-individual relationships between the various objective and subjective methods of internal TL were large to very large (0.62-0.94). Moderate-to-large inverse relationships were found between mean session-RPE TL and various aerobic fitness variables (-0.58 to -0.37). Large-to-very large relationships were found between mean session-RPE TL and on water performance (0.57-0.75). In conclusion, session-RPE is a valid method for monitoring TL for junior Sprint Kayak athletes, regardless of the RPE scale used. The session-RPE TL relates to fitness and performance, supporting the use of session-RPE in Sprint Kayak training.

    Background: Over years, surgical training is changing and years of tradition are being challenged by legal and ethical concerns for patient safety, work hour restrictions, and the cost of operating room time. Surgical simulation and skill training offer an opportunity to teach and practice advanced techniques before attempting them on patients. Simulation training can be as straightforward as using real instruments and video equipment to manipulate simulated “tissue” in a box trainer. More advanced virtual reality (VR) simulators are now available and ready for widespread use. Early systems have demonstrated their effectiveness and discriminative ability. Newer systems enable the development of comprehensive curricula and full procedural simulations. Methods: A PubMed review of the literature was performed for the MESH words “Virtual reality, “Augmented Reality”, “Simulation”, “Training”, and “Neurosurgery”. Relevant articles were retrieved and reviewed. A review of the literature was performed for the history, current status of VR simulation in neurosurgery. Results: Surgical organizations are calling for methods to ensure the maintenance of skills, advance surgical training, and credential surgeons as technically competent. The number of published literature discussing the application of VR simulation in neurosurgery training has evolved over the last decade from data visualization, including stereoscopic evaluation to more complex augmented reality models. With the revolution of computational analysis abilities, fully immersive VR models are currently available in neurosurgery training. Ventriculostomy catheters insertion, endoscopic and endovascular simulations are used in neurosurgical residency training centers across the world. Recent studies have shown the coloration of proficiency with those simulators and levels of experience in the real world. Conclusion: Fully immersive technology is starting to be applied to the practice of

    2013-12-01

    One of the core subjects in university training of the physicians has been General Pathology. Responsibility for this has historically fallen on Internal Medicine specialists. However, we are unaware if this situation is currently maintained. A questionnaire was sent to the coordinators of the subject of the 39 Spanish medical schools to know, among other things, the current denomination of the subjects (traditionally known as «General Pathology»), number of credits, teaching activities included in the subject and number and specialty of the professors responsible for it. Some data from the medical schools that did not respond were obtained from their web pages. A total of 28 of the 39 (72%) medical schools existing in Spain answered the survey. The current denomination of the subject «General Pathology» varied greatly. The mean number of credits (one credit=20-25 h) was 11.2 (range 3 to 29). In 22 of 34 schools (65%), the subject was taught in the third year of the studies, but in 21% of the schools, it was partially and in 15% of the schools, totally, taught in the second year. More than half of the professors (54%) who taught the subject were Internal Medicine specialists, although this responsibility was shared with other specialists in a large proportion. Teaching of General Pathology shows a marked heterogeneity that does not seem to be due to teaching or pedagogic criteria among the different schools of Spain. These facts may be due to less presence in the university setting of Internal Medicine compared to other specialties. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    2017-01-01

    Introduction: The current study examined if adaptive working memory training (Cogmed QM) has the potential to improve inhibitory control, working memory capacity, and perceptions of memory functioning in a group of patients currently on sick leave due to symptoms of pain, insomnia, fatigue, depression and anxiety. Participants who were referred to a vocational rehabilitation center volunteered to take part in the study. Methods: Participants were randomly assigned to either a training condition (N = 25) or a control condition (N = 29). Participants in the training condition received working memory training in addition to the clinical intervention offered as part of the rehabilitation program, while participants in the control condition received treatment as usual i.e., the rehabilitation program only. Inhibitory control was measured by The Stop Signal Task, working memory was assessed by the Spatial Working Memory Test, while perceptions of memory functioning were assessed by The Everyday Memory Questionnaire-Revised. Results: Participants in the training group showed a significant improvement on the post-tests of inhibitory control when compared with the comparison group (p = 0.025). The groups did not differ on the post-tests of working memory. Both groups reported less memory problems at post-testing, but there was no sizeable difference between the two groups. Conclusions: Results indicate that working memory training does not improve general working memory capacity per se. Nor does it seem to give any added effects in terms of targeting and improving self-perceived memory functioning. Results do, however, provide evidence to suggest that inhibitory control is accessible and susceptible to modification by adaptive working memory training. PMID:28111555

  6. Bioinformatics Education in Pathology Training: Current Scope and Future Direction

    Directory of Open Access Journals (Sweden)

    2017-04-01

    Full Text Available Training anatomic and clinical pathology residents in the principles of bioinformatics is a challenging endeavor. Most residents receive little to no formal exposure to bioinformatics during medical education, and most of the pathology training is spent interpreting histopathology slides using light microscopy or focused on laboratory regulation, management, and interpretation of discrete laboratory data. At a minimum, residents should be familiar with data structure, data pipelines, data manipulation, and data regulations within clinical laboratories. Fellowship-level training should incorporate advanced principles unique to each subspecialty. Barriers to bioinformatics education include the clinical apprenticeship training model, ill-defined educational milestones, inadequate faculty expertise, and limited exposure during medical training. Online educational resources, case-based learning, and incorporation into molecular genomics education could serve as effective educational strategies. Overall, pathology bioinformatics training can be incorporated into pathology resident curricula, provided there is motivation to incorporate, institutional support, educational resources, and adequate faculty expertise.

  7. Current Scientific Evidence for a Polarized Cardiovascular Endurance Training Model.

    Science.gov (United States)

    Hydren, Jay R; Cohen, Bruce S

    2015-12-01

    Recent publications have provided new scientific evidence for a modern aerobic or cardiovascular endurance exercise prescription that optimizes the periodization cycle and maximizes potential endurance performance gains in highly trained individuals. The traditional threshold, high volume, and high-intensity training models have displayed limited improvement in actual race pace in (highly) trained individuals while frequently resulting in overreaching or overtraining (physical injury and psychological burnout). A review of evidence for replacing these models with the proven polarized training model seems warranted. This review provides a short history of the training models, summarizes 5 key studies, and provides example training programs for both the pre- and in-season periods. A polarized training program is characterized by an undulating nonlinear periodization model with nearly all the training time spent at a "light" (≤13) and "very hard" (≥17) pace with very limited time at "hard" (14-16) or race pace (6-20 Rating of Perceived Exertion [RPE] scale). To accomplish this, the polarization training model has specific high-intensity workouts separated by one or more long slow distance workouts, with the exercise intensity remaining below ventilatory threshold (VT) 1 and/or blood lactate of less than 2 mM (A.K.A. below race pace). Effect sizes for increasing aerobic endurance performance for the polarized training model are consistently superior to that of the threshold training model. Performing a polarized training program may be best accomplished by: going easy on long slow distance workouts, avoiding "race pace" and getting after it during interval workouts.

  8. Current Developments in Nuclear Density Functional Methods

    2010-01-01

    Density functional theory (DFT) became a universal approach to compute ground-state and excited configurations of many-electron systems held together by an external one-body potential in condensed-matter, atomic, and molecular physics. At present, the DFT strategy is also intensely studied and applied in the area of nuclear structure. The nuclear DFT, a natural extension of the self-consistent mean-field theory, is a tool of choice for computations of ground-state properties and low-lying excitations of medium-mass and heavy nuclei. Over the past thirty-odd years, a lot of experience was accumulated in implementing, adjusting, and using the density-functional methods in nuclei. This research direction is still extremely actively pursued. In particular, current developments concentrate on (i) attempts to improve the performance and precision delivered by the nuclear density-functional methods, (ii) derivations of density functionals from first principles rooted in the low-energy chromodynamics and effective th...

    Purpose: To compare the absolute and relative training load of the Marathon (42k) and the Ironman (IM) training in recreational trained athletes. Methods: Fifteen Marathoners and Fifteen Triathletes participated in the study. Their performance level was the same relative to the sex's absolute winner at the race. No differences were presented neither in age, nor in body weight, height, BMI, running VO2max max, or endurance training experience (p > 0.05). They all trained systematically for their respective event (IM or 42k). Daily training load was recorded in a training log, and the last 16 weeks were compared. Before this, gas exchange and lactate metabolic tests were conducted in order to set individual training zones. The Objective Load Scale (ECOs) training load quantification method was applied. Differences between IM and 42k athletes' outcomes were assessed using Student's test and significance level was set at p Training Weekly Avg Time (IM 12.9 h ± 2.6 vs. 42k 5.2 ± 0.9), and Average Weekly ECOs (IM 834 ± 171 vs. 42k 526 ± 118) were significantly higher in IM (p Training Load and Training Time was superior for 42k runners when comparing ECOs (IM 65.8 ± 11.8 vs. 42k 99.3 ± 6.8) (p training time or load vs. Competition Time were superior for 42k (p Training Time/Race Time: IM 1.1 ± 0.3 vs. 42k 1.7 ± 0.5), (ECOs Training Load/Race Time: IM 1.2 ± 0.3 vs. 42k 2.9 ± 1.0). Conclusions: In spite of IM athletes' superior training time and total or weekly training load, when comparing the ratios between training load and training time, and training time or training load vs. competition time, the preparation of a 42k showed to be harder.

    There is emerging evidence supporting the use vision training, including light board training tools, as a concussion baseline and neuro-diagnostic tool and potentially as a supportive component to concussion prevention strategies. This paper is focused on providing detailed methods for select vision training tools and reporting normative data for comparison when vision training is a part of a sports management program. The overall program includes standard vision training methods including tachistoscope, Brock's string, and strobe glasses, as well as specialized light board training algorithms. Stereopsis is measured as a means to monitor vision training affects. In addition, quantitative results for vision training methods as well as baseline and post-testing *A and Reaction Test measures with progressive scores are reported. Collegiate athletes consistently improve after six weeks of training in their stereopsis, *A and Reaction Test scores. When vision training is initiated as a team wide exercise, the incidence of concussion decreases in players who participate in training compared to players who do not receive the vision training. Vision training produces functional and performance changes that, when monitored, can be used to assess the success of the vision training and can be initiated as part of a sports medical intervention for concussion prevention.

    2000-01-01

    Full Text Available In many education and training institutions in the Central and South Eastern European Transition Countries, training is generally understood as a system of formal courses, not entirely different from education. To a lesser extent, training is based on the flexible training needs analysis based, training modules, courses workshops and seminars. It typically emphasizes teaching rather than learning. It is usually a one-shot exercise for an individual rather than an sequence in continuing, sometimes lifelong learning process and finally, it is understood as something done to trainees by an expert who is regarded as unquestionable authority – otherwise the training is considered irrelevant. The trainer or lecturer should not normally be strongly opposed in the classroom environment. Dialogues, student initiatives, lively classroom discussion with strong counter argumentation are still not dominant.

    A power transmission system includes a first unit for carrying out the steps of receiving high voltage direct current (HVDC) power from an HVDC power line, generating an alternating current (AC) component indicative of a status of the first unit, and adding the AC component to the HVDC power line. Further, the power transmission system includes a second unit for carrying out the steps of generating a direct current (DC) voltage to transfer the HVDC power on the HVDC power line, wherein the HVDC power line is coupled between the first unit and the second unit, detecting a presence or an absence of the added AC component in the HVDC power line, and determining the status of the first unit based on the added AC component.

    Plastic surgery training worldwide has seen a thorough restructuring over the past decade, with the introduction of formal training curricula and work-based assessment tools. Part of this process has been the introduction of revalidation and a greater use of simulation in training delivery. Simulation is an increasingly important tool for educators because it provides a way to reduce risks to both trainees and patients, whilst facilitating improved technical proficiency. Current microsurgery training interventions are often predicated on theories of skill acquisition and development that follow a 'practice makes perfect' model. Given the changing landscape of surgical training and advances in educational theories related to skill development, research is needed to assess the potential benefits of alternative models, particularly cross-training, a model now widely used in non-medical areas with significant benefits. Furthermore, with the proliferation of microsurgery training interventions and therefore diversity in length, cost, content and models used, appropriate standardisation will be an important factor to ensure that courses deliver consistent and effective training that achieves appropriate levels of competency. Key research requirements should be gathered and used in directing further research in these areas to achieve on-going improvement of microsurgery training.

    Conclusions: The use of these different entities to create a standardized curriculum for robotic surgery remains elusive. Selection of training modalities and assessment tools should be based upon performance data-based validity and practical feasibility. Comparative assessment of different modalities (cross-modality validity can help strengthen the development of common skill sets. Constant data collection must occur to guide continuing curriculum improvement.

    Full Text Available The validation of robotic surgery in a growing number of operative procedures has increased its acceptance nationwide and its usage is becoming widespread. Training needs to reflect this fast paced environment to ensure that surgeons continue to progress competently and safely. Current surgical training in the UK is validated through the Intercollegiate Surgical Curriculum Programme (ISCP with progression assessed through an Annual Review of Curriculum Progress (ARCP. There has been some resistance to this since its introduction and many trainees remain dissatisfied with this programme. Training in robotic surgery is currently focused through fellowships with little regular exposure to urology trainees at more junior levels. Robotic simulation provides a useful adjunct to training for both technical and non-technical skills. Its usage is particularly valuable to more inexperienced trainees but may be of limited benefit in those with more advanced skills. Training programmes such as the fundamental skills in robotic surgery (FSRS have been created to facilitate robotic training and it is likely that the future of robotic surgery training will include a combination of theoretical learning, training programmes and fellowship training.-------------------------------------------------------Cite this article as: Chan KE, Vasdev N.

    Reflexology is basically a study of how one part of the human body relates to another part of the body. Reflexology practitioners rely on the reflexes map of the feet and hands to all the internal organs and other human body parts. They believe that by applying the appropriate pressure and massage certain spots on the feet and hands, all other body parts could be energized and rejuvenated. This review aimed to revisit the concept of reflexology and examine its effectiveness, practices, and the training for reflexology practitioners. PubMed, SCOPUS, Google Scholar, and SpringerLink databases were utilized to search the following medical subject headings or keywords: foot massage, reflexology, foot reflexotherapy, reflexological treatment, and zone therapy. The articles published for the last 10 years were included. Previous systematic reviews failed to show concrete evidence for any specific effect of reflexology in any conditions. Due to its non-invasive, non-pharmacological complementary nature, reflexology is widely accepted and anecdotal evidence of positive effect reflexology in a variety of health conditions are available. Adequate training for practitioners is necessary to ensure the consistency of service provided.

    Full Text Available Kidney regeneration is likely to provide an inexhaustible source of tissues and organs for immunosuppression-free transplantation. It is currently garnering considerable attention and might replace kidney dialysis as the ultimate therapeutic strategy for renal failure. However, anatomical complications make kidney regeneration difficult. Here, we review recent advances in the field of kidney regeneration, including (i the directed differentiation of induced pluripotent stem cells/embryonic stem cells into kidney cells; (ii blastocyst decomplementation; (iii use of a decellularized cadaveric scaffold; (iv embryonic organ transplantation; and (v use of a nephrogenic niche for growing xenoembryos for de novo kidney regeneration from stem cells. All these approaches represent potentially promising therapeutic strategies for the treatment of patients with chronic kidney disease. Although many obstacles to kidney regeneration remain, we hope that innovative strategies and reliable research will ultimately allow the restoration of renal function in patients with end-stage kidney disease.

    Full Text Available The current models of development are changing the balance between human activity and Nature on a local ands global level and the urgent need to establish a new relationship between Man and the environment is increasingly apparent. The move towards a more caring approach to the planet introducing concepts such as limits, impact on future generations, regeneration of resources, social and environmental justice and the right to citizenship should make us consider (aside from international undertakings by governments exactly how we can promote a culture of sustainability in schools in terms of methods, time scales, and location. Schools are directly involved in these processes of change however it is necessary to plan carefully and establish situations that will result in greater attention being paid to the interaction between man and the environment, and highlighting the lifestyles and attitudes that are currently incompatible with a sustainable future. These solutions, although based on technical-scientific knowledge, cannot be brought about without the involvement of the individual and local agencies working together. However we have chosen to concentrate on the links between educational policies and local areas interpreting declarations made by international bodies such as UNESCO and suggestions aimed at bringing sustainability to the centre of specific policies. Bringing about these aims requires great educational effort that goes well beyond simple environmental education since it requires a permanent process for educating adults. Looking at stages of the history of the theories regarding the development and education of adults shows how the topic of sustainability made its entry into the debate about permanent education and how in the last ten years it has taken on an unrivalled importance as a point of reference for educational policies and pedagogical reflection.

    Vertebral fractures are the hallmark of osteoporosis and are associated with increased morbility and mortality. Because a majority of vertebral fractures often occur in absence of specific trauma and are asymptomatic, their identification is radiographic. The two most widely used methods to determine the severity of vertebral fractures are the visual semiquantitative (SQ) assessment and the morphometric quantitative approach, involving the measurements of vertebral body heights. The measurements may be made on conventional spinal radiographs (MRX: morphometric X-ray radiography) or on images obtained from dual X-ray absorptiometry (DXA) scans (MXA: morphometric X-ray absorptiometry).The availability of a rapid, low-dose method for assessment of vertebral fractures, using advanced fan-beam DXA devices, provides a practical method for integrated assessment of BMD and vertebral fracture status. The visual or morphometric assessment of lateral DXA spine images may have a potential role for use as a prescreening tool, excluding normal subjects prior to performing conventional radiographs.

    The Fluoride Volatility Method is based on a separation process, which comes out from the specific property of uranium, neptunium and plutonium to form volatile hexafluorides whereas most of fission products (mainly lanthanides) and higher transplutonium elements (americium, curium) present in irradiated fuel form nonvolatile tri-fluorides. Fluoride Volatility Method itself is based on direct fluorination of the spent fuel, but before the fluorination step, the removal of cladding material and subsequent transformation of the fuel into a powdered form with a suitable grain size have to be done. The fluorination is made with fluorine gas in a flame fluorination reactor, where the volatile fluorides (mostly UF{sub 6}) are separated from the non-volatile ones (trivalent minor actinides and majority of fission products). The subsequent operations necessary for partitioning of volatile fluorides are the condensation and evaporation of volatile fluorides, the thermal decomposition of PuF{sub 6} and the finally distillation and sorption used for the purification of uranium product. The Fluoride Volatility Method is considered to be a promising advanced pyrochemical reprocessing technology, which can mainly be used for the reprocessing of oxide spent fuels coming from future GEN IV fast reactors.

    Full Text Available Background: There is consensus among stakeholders in Cameroon on the need to develop and strengthen human resource capacity for nutrition. This study was conducted to provide a comprehensive mapping of the current capacity for tertiary-level human nutrition training in Cameroon. Design: Participating institutions included university-level institutions offering dedicated nutrition degree programs or other programs in which nutrition courses were taught. A semi-structured questionnaire administered during in-person interviews was used to collect data on existing programs and content of training curricula. Nutrition curricula were reviewed against the following criteria: intended objectives, coverage of nutrition topics, and teaching methods. Results: In total, five nutrition degree programs (four undergraduate programs and one master's program were identified. Three additional programs were about to be launched at the time of data collection. We did not find any doctorate degree programs in nutrition. All the undergraduate programs only had little focus on public health nutrition whereas the master's program in our sample offered a good coverage of all dimensions of human nutrition including basic and applied nutrition. The predominant teaching method was didactic lecture in all the programs. We did not find any formal documentation outlining the competencies that students were expected to gain upon completion of these programs. Nutrition courses in agricultural and health schools were limited in terms of contact hours and scope. Public health nutrition was not covered in any of the health professional schools surveyed. We found no institution offering in-service nutrition training at the time of the study. Conclusions: Based on our findings, we recommend that nutrition training programs in Cameroon be redesigned to make them more responsive to the public health needs of the country.

  10. Method for Estimating Low-Frequency Return Current of DC Electric Railcar

    Science.gov (United States)

    Hatsukade, Satoru

    The Estimation of the harmonic current of railcars is necessary for achieving compatibility between train signaling systems and railcar equipment. However, although several theoretical analyses methods for estimating the harmonic current of railcars using switching functions exist, there are no theoretical analysis methods estimating a low-frequency current at a frequency less than the power converter's carrier frequency. This paper describes a method for estimating the spectrum (frequency and amplitude) of the low-frequency return current of DC electric railcars. First, relationships between the return current and characteristics of the DC electric railcars, such as mass and acceleration, are determined. Then, the mathematical (not numerical) calculation results for low-frequency current are obtained from the time-current curve for a DC electric railcar by using Fourier series expansions. Finally, the measurement results clearly show the effectiveness of the estimation method development in this study.

    Neuroimaging has gained widespread use in neuropsychological research and practice. However, there are neither established guidelines on how neuropsychologists might become competent researchers or consumers of neuroimaging data, nor any published studies describing the state of neuroimaging training among neuropsychologists. We report the results of two online surveys, one of 13 expert neuropsychologist-neuroimagers whose responses informed the formulation of a second, larger survey to neuropsychologists-at-large that were a random selection of a third of the members of the International Neuropsychological Society and American Academy of Clinical Neuropsychology. A total of 237 doctoral-level neuropsychologists, or 15.3% of potential participants, provided complete responses. Most respondents (69.2%) received training in neuroimaging, mostly at the post-doctoral level, largely through independent study, clinical conferences, instruction by clinical supervisors, and individualized mentoring, on topics such as neuroimaging modalities in neurology, neuroanatomy, and the appropriate information to glean from neuroradiology reports. Of the remaining respondents who did not receive training in neuroimaging, 64.4% indicated that such training would be very or extremely beneficial to one's career as a neuropsychologist. Both neuropsychologist-neuroimagers and neuropsychologists-at-large provided specific recommendations for training. Findings from this initial effort will guide trainees who seek to develop competence in neuroimaging, and inform future formulations of neuropsychological training.

    1993-07-01

    The use of weights is an increasingly popular conditioning technique, competitive sport and recreational activity among children, adolescents and young adults. Weight-training can cause significant musculoskeletal injuries such as fractures, dislocations, spondylolysis, spondylolisthesis, intervertebral disk herniation, and meniscal injuries of the knee. Although injuries can occur during the use of weight machines, most apparently happen during the aggressive use of free weights. Prepubescent and older athletes who are well trained and supervised appear to have low injury rates in strength training programmes. Good coaching and proper weightlifting techniques and other injury prevention methods are likely to minimise the number of musculoskeletal problems caused by weight-training.

    2010-11-01

    Fitness managers play an integral role in the day-to-day operation of the facilities in which they work. One of the most critical responsibilities is that of hiring, training, and supervising personal trainers. Research studies have identified a number of qualities and competencies that an effective exercise leader is required to have, but there is little scholarly work addressing managers' attitudes surrounding the performance of personal trainers. Using focus group methodology, managers of personal trainers were recruited to provide viewpoints related to desirable qualities of personal trainers and opinions regarding certification and academic preparation. Responses of the participants were transcribed, coded, and analyzed for themes. Two global themes, Selection Rationale and Negative Characteristics, emerged. Selection Rationale consisted of qualities that influence a manager's decision to hire a particular trainer (e.g., physique, education, social skills). Negative characteristics referred to qualities considered unethical or unprofessional (e.g., sexual comments, misuse of power) and the consequences of those behaviors (e.g., loss of clients, potential for litigation). The results suggest that undergraduate exercise science programs devote additional time toward the development of the affective qualities of future fitness trainers. Managers also recommended licensure for employees.

    Increasing greenhouse gaseous concentration in the atmosphere is perturbing the environment to cause grievous global warming and associated consequences. Following the rule that only measurable is manageable, mensuration of greenhouse gas intensiveness of different products, bodies, and processes is going on worldwide, expressed as their carbon footprints. The methodologies for carbon footprint calculations are still evolving and it is emerging as an important tool for greenhouse gas management. The concept of carbon footprinting has permeated and is being commercialized in all the areas of life and economy, but there is little coherence in definitions and calculations of carbon footprints among the studies. There are disagreements in the selection of gases, and the order of emissions to be covered in footprint calculations. Standards of greenhouse gas accounting are the common resources used in footprint calculations, although there is no mandatory provision of footprint verification. Carbon footprinting is intended to be a tool to guide the relevant emission cuts and verifications, its standardization at international level are therefore necessary. Present review describes the prevailing carbon footprinting methods and raises the related issues.

    The structural integrity of wheelsets used in rolling stock is of great importance to the safety. In this paper, electromagnetic system with an eddy current transducer suitable for the inspection of hollow axles have been presented. The transducer was developed to detect surface braking defects having depth not smaller than 0.5 mm. Ultrasound technique can be utilized to inspect the whole axle, but it is not sufficiently sensitive to shallow defects located close to the surface. Therefore, the electromagnetic technique is proposed to detect surface breaking cracks that cannot be detected by ultrasonic technique.

  2. Transport critical current of MgB2 wires: pulsed current of varying rate compared to direct current method

    See, K. W.; Xu, X.; Horvat, J.; Cook, C. D.; Dou, S. X.

    2011-10-01

    The measurement of transport critical current (Ic) for MgB2 wires and tapes has been investigated with two different techniques, the conventional four-probe arrangement with direct current (DC) power source, and a tailored triangle pulse at different rates of current change. The DC method has been widely used and practiced by various groups, but suffers from inevitable heating effects when high currents are used at low magnetic fields. The pulsed current method has no heating effects, but the critical current can depend on the rate of the current change (dI/dt) in the pulse. Our pulsed current measurements with varying dI/dt show that the same values of Ic are obtained as with the DC method, but without the artifacts of heating. Our method is particularly useful at low field regions which are often inaccessible by DC methods. We also performed a finite element method (FEM) analysis to obtain the time dependent heat distribution in MgB2 due to the electric potential produced at the current contacts to the superconducting sample and its gradient around the contacts. This gradient is defined as the current transfer length (CTL) of the samples and leads to Joule heating of the wire near the contacts. The FEM results provide further evidence of the limitation of the DC method in obtaining high transport critical current.

    Full Text Available In the 1970s, Helen Bonny developed the Bonny Method of Guided Imagery and Music for use as a primary process of receptive music psychotherapy in long-term therapy. Training programs in the method traditionally taught it for use in this manner. Over the last two decades, however, modifications of the Bonny Method for use in short term therapy have inspired innovations in training. As a part of this movement, the Anna Maria College training program is innovative in three main areas: a the music and imagery methods used to train students, b the processes of personal development in which students are engaged, and c the processes used for distance supervision and peer interaction.

    2004-12-01

    Full Text Available The estimation of the standard deviation of noise contaminating an image is a fundamental step in wavelet-based noise reduction techniques. The method widely used is based on the mean absolute deviation (MAD. This model-based method assumes specific characteristics of the noise-contaminated image component. Three novel and alternative methods for estimating the noise standard deviation are proposed in this work and compared with the MAD method. Two of these methods rely on a preliminary training stage in order to extract parameters which are then used in the application stage. The sets used for training and testing, 13 and 5 images, respectively, are fully disjoint. The third method assumes specific statistical distributions for image and noise components. Results showed the prevalence of the training-based methods for the images and the range of noise levels considered.

    2017-06-01

    Electromagnetic levitation (EMS) maglev train relies on the attraction between the electromagnets and rails which are mounted on the train to achieve suspension. During the movement, the magnetic field generated by the electromagnet will induce the eddy current in the orbit and the eddy current will weaken the suspended magnetic field. Which leads to the attenuation of the levitation force, the increases of suspension current and the degradation the suspension performance. In this paper, the influence of eddy current on the air gap magnetic field is solved by theoretical analysis, and the correction coefficient of air gap magnetic field is fitted according to the finite element data. The levitation force and current are calculated by the modified formula, and the velocity curves of the levitation force and current are obtained. The results show that the eddy current effect increases the load power by 61.9% in the case of heavy loads.

  6. Neuroimaging training among neuropsychologists: A survey of the state of current training and recommendations for trainees

    Neuroimaging has gained widespread use in neuropsychological research and practice. However, there are neither established guidelines on how neuropsychologists might become competent researchers or consumers of neuroimaging data, nor any published studies describing the state of neuroimaging training among neuropsychologists. We report the results of two online surveys, one of 13 expert neuropsychologist-neuroimagers, whose responses informed the formulation of a second, larger survey to neur...

    2015-01-01

    Cross-country skiing is a low injury-risk sport that has many health benefits and few long-term health risks. Some concern exists that cross-country skiing may be associated with a higher incidence of atrial fibrillation; however, mortality rates among skiers are lower than those among the general population. While continuing to emphasize aerobic and anaerobic training, training methods also should promote ski-specific strength training to increase maximum force and its rate of delivery and to build muscular endurance to maintain that power through a race. Multiple tests are available to monitor training progress. Which tests are most appropriate depends on the specific events targeted. In addition to laboratory-based tests, there also are many simpler, more cost-effective tests, such as short time trials, that can be used to monitor training progress and predict performance particularly at the junior skier level where access and cost may be more prohibitive.

    2011-01-01

    Background There has been an increasing role of advanced minimally invasive procedures in hepatopancreatobilliary (HPB) surgery. However, there are no set minimum laparoscopic case requirements. Methods A 14-question electronic survey was sent to 82 worldwide HPB fellowship programme directors. Results Forty-nine per cent (n = 40) of the programme directors responded. The programmes were predominantly university based (83%). Programmes had either one (55%) or two fellows (40%) each year. Programmes (35–48%) had average annual volumes of 51–100 hepatic, 51–100 pancreatic and 25–50 biliary cases. For many programmes, <10% of hepatic (48%), pancreatic (40%) and biliary (70%) cases were done laparoscopically. The average annual fellow case volumes for hepatic, pancreatic and biliary surgeries were 25–50 (62%), 25–50 (47%) and <25 (50%), respectively. The average annual number of hepatic, pancreatic and biliary cases done laparoscopically by a fellow was 9, 9 and 4, which constitutes 36%, 36% and 16%, respectively, of the International Hepato-Pancreato-Billiary Association (IHPBA) requirement. Conclusion We surmise that the low average number of surgeries performed by minimally-invasive techniques by HPB fellows is not sufficient in today's practice. Should there be an increase in the minimal number of hepatic, pancreatic and complex biliary cases to 50, 50, and 25, with at least 50% of these performed laparoscopically? PMID:21309929

    Full Text Available In Finland the Regional Fire and Rescue Services (RFRS are responsible for near shore oil spill response and shoreline cleanup operations. In addition, they assist in other types of maritime incidents, such as search and rescue operations and fire-fighting on board. These statutory assignments require the RFRS to have capability to act both on land and at sea. As maritime incidents occur infrequently, little routine has been established. In order to improve their performance in maritime operations, the RFRS are participating in a new oil spill training programme to be launched by South-Eastern Finland University of Applied Sciences. This training programme aims to utilize new educational methods; e-learning and simulator based training. In addition to fully exploiting the existing navigational bridge simulator, radio communication simulator and crisis management simulator, an entirely new simulator is developed. This simulator is designed to model the oil recovery process; recovery method, rate and volume in various conditions with different oil types. New simulator enables creation of a comprehensive training programme covering training tasks from a distress call to the completion of an oil spill response operation. Structure of the training programme, as well as the training objectives, are based on the findings from competence and education surveys conducted in spring 2016. In these results, a need for vessel maneuvering and navigation exercises together with actual response measures training were emphasized. Also additional training for maritime radio communication, GMDSS-emergency protocols and collaboration with maritime authorities were seemed important. This paper describes new approach to the maritime operations training designed for rescue authorities, a way of learning by doing, without mobilising the vessels at sea.

    2017-02-01

    In this paper, we have experimentally investigated the optimized bias current of semiconductor optical amplifiers (SOAs) to achieve high-speed input pulse train amplification with high gain and low distortion. Variations of the amplified output pulse duration with the amplifier bias currents have been analyzed and, compared to the input pulse duration, the amplified output pulse duration is broadened. As the SOA bias current decreases from the high level (larger than the saturated bias current) to the low level, the broadened pulse duration of the amplified output pulse initially decreases slowly and then rapidly. Based on the analysis, an optimized bias current of SOA for high-speed pulse train amplification is introduced. The relation between the SOA optimized bias current and the parameters of the input pulse train (pulse duration, power, and repetition rate) are experimentally studied. It is found that the larger the input pulse duration, the lower the input pulse power or a higher repetition rate can lead to a larger SOA optimized bias current, which corresponds to a larger optimized SOA gain. The effects of assist light injection and different amplifier temperatures on the SOA optimized bias current are studied and it is found that assist light injection can effectively increase the SOA optimized bias current while SOA has a lower optimized bias current at the temperature 20°C than that at other temperatures.

    Full Text Available Resident training of neurosurgical specialization will be tried and carried out in all over China. From the point of view of training base hospitals, a majority of 3A level hospitals have sufficient patients and good equipments which will ensure the success of training process; however, division of subspecialty, teaching motivation and teaching method still have a great potential to improve. In order to establish and improve training bases for residents of specialization, supervision from national administrative department should be strengthened; professional society also plays an important role in standardizing and controlling the training quality. Considering our nation's situation, integration of postgraduate education and resident training is worth of discussion. DOI: 10.3969/j.issn.1672-6731.2015.07.015

  16. Rail temperature rise characteristics caused by linear eddy current brake of high-speed train

    2014-12-01

    Full Text Available The rail temperature rises when the linear eddy current brake of high-speed train is working, which may lead to a change of rail physical characteristics or an effect on train operations. Therefore, a study concerning the characteristics of rail temperature rise caused by eddy current has its practical necessity. In the research, the working principle of a linear eddy current brake is introduced and its FEA model is established. According to the generation mechanism of eddy current, the theoretical formula of the internal energy which is produced by the eddy current is deduced and the thermal load on the rail is obtained. ANSYS is used to simulate the rail temperature changes under different conditions of thermal loads. The research result shows the main factors which contribute to the rising of rail temperature are the train speed, brake gap and exciting current. The rail temperature rises non-linearly with the increase of train speed. The rail temperature rise curve is more sensitive to the exciting current than the air gap. Moreover, the difference stimulated by temperature rising between rails of 60 kg/m and 75 kg/m is presented as well.

    2016-01-01

    Full Text Available Surgery has traditionally been an important aspect of services offered by mission hospitals, but only in the last 20 years has surgical residency training been incorporated into the mission hospital setting. A working group of surgical educators met in conjunction with the Global Missions Health Conference in November 2015 and discussed the current status of surgical training in the mission setting. This paper outlines the current status and makes recommendations for mission groups who are contemplating starting a residency training program. Potential difficulties and the importance of regional recognition of the program are discussed. The work group felt that it was important to include a strong spiritual emphasis as part of the training. Future directions and the concern about employment opportunities are explored.

    Objective. Transcranial direct current stimulation (tDCS) and user training (UT) are two types of methods to improve myoelectric control performance for amputees. In this study, we compared the independent effect between tDCS and UT, and investigated the combined effect of tDCS and UT. Approach. An online paradigm of simultaneous and proportional control (SPC) based on electromyography (EMG) was adopted. The proposed experiments were conducted on six naïve unilateral trans-radial amputees. The subjects each received three types of 20 min interventions: active tDCS with motor training (tDCS  +  UT), active tDCS with quiet sitting (tDCS), and sham tDCS with motor training (UT). The interventions were applied at one week intervals in a randomized order. The subjects performed online control of a feedback arrow with two degrees of freedom (DoFs) to accomplish target reaching motor tasks in pre-sessions and post-sessions. We compared the performance, measured by completion rate, completion time, and efficiency coefficient, between pre-sessions and post-sessions. Main results. The results showed that the intervention tDCS  +  UT and tDCS significantly improved the online SPC performance (i.e. improved the completion rate; reduced the completion time; and improved the efficiency coefficient), while intervention UT did not significantly change the performance. The results also showed that the online SPC performance after intervention tDCS  +  UT and tDCS was not significantly different, but both were significantly better than that after intervention UT. Significance. tDCS could be an effective intervention to improve the online SPC performance in a short time.

    In the process of spectral reflectance reconstruction, sample selection plays an important role in the accuracy of the constructed model and in reconstruction effects. In this paper, a method for training sample selection based on camera response is proposed. It has been proved that the camera response value has a close correlation with the spectral reflectance. Consequently, in this paper we adopt the technique of drawing a sphere in camera response value space to select the training samples which have a higher correlation with the test samples. In addition, the Wiener estimation method is used to reconstruct the spectral reflectance. Finally, we find that the method of sample selection based on camera response value has the smallest color difference and root mean square error after reconstruction compared to the method using the full set of Munsell color charts, the Mohammadi training sample selection method, and the stratified sampling method. Moreover, the goodness of fit coefficient of this method is also the highest among the four sample selection methods. Taking all the factors mentioned above into consideration, the method of training sample selection based on camera response value enhances the reconstruction accuracy from both the colorimetric and spectral perspectives.

    Although many studies have demonstrated the efficacy of strength training in increasing energetic expenditure (EE) both during and after training sessions, there are no studies available that analyze the influence on EE of the order in which exercises are performed. Accordingly, the objective of this study was to verify whether the order in which exercises are performed, represented by 2 different methods of strength training (circuit [CT] and pre-exhaustion [PE]), influences the magnitude of the excess postexercise oxygen consumption (EPOC) as well as the EE. Eight nonstrength-trained women participated in the study. Two strength training sessions, with different orders of execution, were held with 7 exercises performed with loads of between 50% and 55% of 1 repetition maximum (1RM). The oxygen uptake was measured before the training sessions, and the difference between the values found was taken as the EPOC of each training session and used in later analysis. No significant differences were found in either the EPOC (CT: 7.19 L +/- 6.17 an. PE: 7.22 +/- 5.84 L) or the postexercise EE (CT: 34.67 +/- 29.76 Kcal, PE: 34.77 +/- 28.15 Kcal) of the 2 training methodologies. Our results indicate that, in strength training, the magnitude of the EPOC is not linked to the order in which the exercises are performed. However, the absence of recovery periods between the sets and the exercises promotes an increase in the magnitude of the EPOC to the levels found in training sessions with higher percentages of 1RM.

    Full Text Available This paper presents a new lower limb rehabilitation robot (hereafter, referred to as LLR-Ro to help patients with lower limb disorder recover their movement function. Based on the ergonomics and kinematics principle, the motion of a human lower limb is analysed, which provides a theoretical basis for the leg mechanism design of LLR-Ro. This paper also proposes a teaching training method for improving the training performance of LLR-Ro. When a physician trains the lower limb of a patient, the acceleration data of the patient's lower limb motion will be collected through a wireless data acquisition system. The data can reproduce the movement trajectory of the physician rehabilitation training and this can be used as the training trajectory of LLR-Ro. The experiment results of this study demonstrate that the teaching training method is feasible. The theory analysis and experimental research of LLR-Ro lay the foundations for the future clinical application of this method.

    2013-01-01

    Full Text Available Neural spike train analysis is an important task in computational neuroscience which aims to understand neural mechanisms and gain insights into neural circuits. With the advancement of multielectrode recording and imaging technologies, it has become increasingly demanding to develop statistical tools for analyzing large neuronal ensemble spike activity. Here we present a tutorial overview of Bayesian methods and their representative applications in neural spike train analysis, at both single neuron and population levels. On the theoretical side, we focus on various approximate Bayesian inference techniques as applied to latent state and parameter estimation. On the application side, the topics include spike sorting, tuning curve estimation, neural encoding and decoding, deconvolution of spike trains from calcium imaging signals, and inference of neuronal functional connectivity and synchrony. Some research challenges and opportunities for neural spike train analysis are discussed.

  6. A hybrid training method for neural energy estimation in calorimetry

    2001-01-01

    A neural mapping is developed to improve the overall performance of Tilecal, which is the hadronic calorimeter of the ATLAS detector. Feeding the input nodes of a multilayer feedforward neural network with the energy values sampled by the calorimeter cells in beam tests, it is shown that the original energy scale of pion beams is reconstructed over a wide energy range and linearity is significantly improved. As it happens for classical methods, a compromise between nonlinearity correction and the optimization of the energy resolution of the detector has to be accomplished. A hybrid training method for the neural mapping is proposed to achieve this design goal. Using the backpropagation algorithm, the method intercalates an epoch of training steps, for which the neural mapping mainly focus on linearity correction, with another block of training steps, in which the original energy resolution obtained by linearly combining the calorimeter cells becomes the main target.

    Unity power factor (UPF) harmonic current detection method applied to active power filter (APF) is presented in this paper. The intention of this method is to make nonlinear loads and active power filter in parallel to be an equivalent resistance. So after compensation, source current is sinusoidal, and has the same shape of source voltage. Meanwhile, there is no harmonic in source current, and the power factor becomes one. The mathematic model of proposed method and the optimum project for equivalent low pass filter in measurement are presented. Finally, the proposed detection method applied to a shunt active power filter experimental prototype based on DSP TMS320F2812 is developed. Simulation and experiment results indicate the method is simple and easy to implement, and can obtain the real-time calculation of harmonic current exactly.

    Best, Krista L; Routhier, François; Miller, William C

    2015-01-01

    To describe current practices for manual wheelchair (MWC) skills training in Canadian rehabilitation centers. An online survey was sent to practice leaders in occupational (OT) and physical therapy (PT) at 87 Canadian rehabilitation centers. Responses were solicited from individuals who could report about wheelchair skills training at facilities with at least 10 beds designated for rehabilitation. Thirty-four questions asked about: (1) demographics, (2) components of MWC training, (3) amount of MWC skills training, (4) use of validated programs and (5) perceived barriers to using validated programs. Data were analyzed using summary statistics. About 68/87 responses were received primarily from OTs (42/68). Basic MWC skills training (e.g. wheel-locks) was consistently part of clinical practice (45/68), while advanced skills training (e.g. curb-cuts) was rare (8/68). On an average, 1-4 h of training was done (29/68). Validated training programs were used by 16/68, most of whom used them "rarely" (7/16). Common barriers to using validated programs were lack of time (43/68) and resources (39/68). Learning to use a wheelchair is important for those with ambulation impairments because the wheelchair enables mobility and social participation. Providing opportunities for advanced wheelchair skills training may enhance mobility and social participation in a safe manner. Implications for Rehabilitation There is evidence confirming the benefits of a validated wheelchair skills program, yet most clinicians do no not use them. A variety of perceived barriers may help to explain the limited use of existing programs, such as time, resources and knowledge. Effective knowledge translation efforts may help alleviate some of these barriers, and novel wheelchair training approaches may alleviate some burden on clinicians to help accommodate the increasing number of older wheelchair users.

    Minimally Invasive Surgery (MIS) is getting more and more important in our specialty. However, the formation of the residents on MIS is, in many cases, irregular. The purpose of this study is to assess the state of training in MIS among the residents of Pediatric Surgery and their potential weaknesses. An electronic survey was distributed among 71 residents of Pediatric Surgery from 17 national hospitals. The response rate was 70.2%.100% of the residents are interested in a broadening of training activities in MIS. The main areas of interest are gastrointestinal (92%) and thoracic (47%) surgery. Only 57% have access to training facilities and less than half of them attend to courses and conferences. 80% believe that they are not given adequate attention from specialized associations. 52% think they should do rotations at referral centers, 86% that courses and seminars should be enhanced, and 44% that the responsibility of the resident in surgery should be increased. The main defects encountered in their training are scarce volume of patients, lack of financial support and overcoming the learning curve of surgeons in their services. Despite the advance of the MIS, resident's training in this discipline still has shortcomings, as expressed in their views. Knowledge of the current state of training should be the starting point for designing a training strategy that ensures adequate skills.

    Full Text Available Stephen J Heller, Jeffrey L TokarDepartment of Medicine, Fox Chase Cancer Center, Philadelphia, PA, USAAbstract: Rapid growth in the field of advanced gastrointestinal endoscopy has led to an increase in specialized therapeutic endoscopy fellowships. The cornerstones of these programs are training in endoscopic retrograde cholangiopancreatography (ERCP and endoscopic ultrasound. These procedures are more complex and challenging to master than routine colonoscopy and upper endoscopy, and in the case of ERCP, higher risk. The concentration of the educational experience in the hands of relatively fewer trainees with specialized interest in advanced endoscopy has resulted in providing a focused cohort of graduating fellows with higher case volumes in training, which likely enhances diagnostic and therapeutic success and safer performance of these procedures. Endoscopic simulators, although not currently in widespread use, have the potential to improve advanced procedural training without jeopardizing patient safety.Keywords: gastrointestinal endoscopy, training, procedures, safety

    The emergence of Acinetobacter baumannii during recent decades as an important nosocomial pathogen responsible of worldwide, intensively documented, outbreaks has resulted in a need for effective epidemiological typing methods. Throughout the years, many typing methods for A. baumannii epidemiological studies have been proposed from phenotypic to molecular methods. Currently, the use of phenotypic typing methods have declined considerably and been progressively replaced by molecular methods. In this review, we introduce the current molecular methods available for A. baumannii typing. Each method has its own advantages and disadvantages, and the selection of an appropriate genotyping method depends on studied objectives. This review sheds light on questions in different epidemiological settings and most molecular methods used to fit these objectives.

    Full Text Available A career in surgery in the United Kingdom demands a commitment to a long journey of assessment. The assessment methods used must ensure that the appropriate candidates are selected into a programme of study or a job and must guarantee public safety by regulating the progression of surgical trainees and the certification of trained surgeons. This review attempts to analyse the psychometric properties of various assessment methods used in the selection of candidates to medical school, job selection, progression in training, and certification. Validity is an indicator of how well an assessment measures what it is designed to measure. Reliability informs us whether a test is consistent in its outcome by measuring the reproducibility and discriminating ability of the test. In the long journey of assessment in surgical training, the same assessment formats are frequently being used for selection into a programme of study, job selection, progression, and certification. Although similar assessment methods are being used for different purposes in surgical training, the psychometric properties of these assessment methods have not been examined separately for each purpose. Because of the significance of these assessments for trainees and patients, their reliability and validity should be examined thoroughly in every context where the assessment method is being used.

    Studies attempting to increase working memory (WM) capacity show promise in enhancing related cognitive functions but have also raised criticism in the broader scientific community given the inconsistent findings produced by these studies. Transcranial direct current stimulation (tDCS) has been shown to enhance WM performance in a single session [Fregni, F., Boggio, P., Nitsche, M., Bermpohl, F., Anatal, A., Feredoes, E., et al. Anodal transcranial direct current stimulation of prefrontal cortex enhances working memory. Experimental Brain Research, 166, 23-30, 2005]; however, the extent to which tDCS might enhance learning on a WM training regime and the extent to which learning gains might transfer outside the training task remains largely unknown. To this end, participants engaged in an adaptive WM training task [previously utilized in Richmond, L., Morrison, A., Chein, J., & Olson, I. Working memory training and transfer in older adults. Psychology & Aging, 26, 813-822, 2011; Chein, J., & Morrison, A. Expanding the mind's workspace: Training and transfer effects with a complex working memory span task. Psychonomic Bulletin & Review, 17, 193-199, 2010] for 10 sessions over 2 weeks, concurrent with either active or sham stimulation of dorsolateral pFC. Before and after training, a battery of tests tapping domains known to relate to WM abilities was administered. Results show that tDCS enhanced learning on the verbal portion of the training task by 3.65 items. Furthermore, tDCS was shown to enhance near transfer to other untrained WM tasks in comparison with a no-contact control group. These results lend support to the idea that tDCS might bolster training and transfer gains in populations with compromised WM abilities.

    Full Text Available Purpose: significant increase of students’ physical condition and health level at the account of application of modern power cardio training methodic. Material: 120 students (60 boys and 60 girls participated in the research. The age of the tested was 19 years. The research took one year. We used methodic of power and functional impact on trainees’ organism (HOT IRON. Such methodic is some systems of physical exercises with weights (mini-barbells, to be fulfilled under accompaniment of specially selected music. Results: we showed advantages of power-cardio and fitness trainings in students’ health improvement and in elimination obesity. Control tests showed experimental group students achieved confidently higher physical indicators. Boys demonstrated increase of physical strength and general endurance indicators. Girls had confidently better indicators of physical strength, flexibility and general endurance. Increase of control group students’ body mass can be explained by students’ insufficient physical activity at trainings, conducted as per traditional program. Conclusions: students’ trainings by power-cardio methodic with application HOT IRON exercises facilitate development the following physical qualities: strength and endurance in boys and strength, flexibility and endurance in girls. Besides, it was found that such systems of exercises facilitate normalization of boys’ body mass and correction of girls’ constitution.

    2009-07-01

    Blood transfusion depends on availability of donor material, and concerns over supply and safety have spurred development of methods to manufacture blood from stem cells. Current methods could theoretically yield therapeutic doses of red blood cells (RBCs) and platelets. However, due to the very large number of cells required to have any impact on supply (currently 10(19) RBC/year in the US), realization of routine manufacture faces significant challenges. Current yields are orders of magnitude too low for production of meaningful quantities, and the physical scale of the problem is a challenge in itself. We discuss these challenges in relation to current methods and how it might be possible to realize limited 'blood pharming' of neutrophils in the near future.

    The objectives of this study were to explore current provision of laparoscopic simulation training, and to determine attitudes of trainers and trainees to the role of simulators in surgical training across the UK. An anonymous cross-sectional survey with cluster sampling was developed and circulated. All Royal College of Obstetricians and Gynaecologists (RCOG) Training Programme Directors (TPD), College Tutors (RCT) and Trainee representatives (TR) across the UK were invited to participate. One hundred and ninety-six obstetricians and gynaecologists participated. Sixty-three percent of hospitals had at least one box trainer, and 14.6% had least one virtual-reality simulator. Only 9.3% and 3.6% stated that trainees used a structured curriculum on box and virtual-reality simulators, respectively. Respondents working in a Large/Teaching hospital (p = 0.008) were more likely to agree that simulators enhance surgical training. Eighty-nine percent agreed that simulators improve the quality of training, and should be mandatory or desirable for junior trainees. Consultants (p = 0.003) and respondents over 40 years (p = 0.011) were more likely to hold that a simulation test should be undertaken before live operation. Our data demonstrated, therefore, that availability of laparoscopic simulators is inconsistent, with limited use of mandatory structured curricula. In contrast, both trainers and trainees recognise a need for greater use of laparoscopic simulation for surgical training.

    2011-08-01

    As clinical forensic medicine (CFM) is not currently recognised as a speciality in the UK there are no nationally agreed mandatory standards for training forensic physicians in either general forensic (GFM) or sexual offence medicine (SOM). The General Medical Council (GMC), the medical regulator in the UK, has issued clear standards for training in all specialities recommending that "trainees must be supported to acquire the necessary skills and experience through induction, effective educational supervision, an appropriate workload and time to learn". In order to evaluate the current situation in the field of clinical forensic medicine, doctors who have recently (within the last two years) started working in the field "trainees" (n = 38), and trainers (n = 61) with responsibility for clinical and educational supervision of new trainees, were surveyed by questionnaire to gather their perceptions of how the relevant GMC standards are being met in initial on-the-job training. Telephone interviews were performed with eleven doctors working as clinical or medical directors to determine their views. It is clear that currently the quality of training in CFM is sub-standard and inconsistent and that the published standards, as to the minimum requirement for training that must be met by post-graduate medical and training providers at all levels, are not being met. The Faculty of Forensic and Legal Medicine (FFLM) needs to set explicit minimum standards which will comply with the regulator and work to pilot credentialing for forensic physicians. A number of recommendations are made for urgent FFLM development.

    2002-01-01

    Overfitting is one of the important problems that restrain the application of neural network. The traditional OBD (Optimal Brain Damage) algorithm canavoid overfitting effectively. But it needs to train the network repeatedly with low calculational efficiency. In this paper, the Marquardt algorithm is incorporated into the OBD algorithm and a new method for pruning network-the Dynamic Optimal Brain Damage (DOBD) is introduced. This algorithm simplifies a network and obtains good generalization through dynamically deleting weight parameters with low sensitivity that is defined as the change of error function value with respect to the change of weights. Also a simplified method is presented through which sensitivities can be calculated during training with a little computation. Arule to determine the lower limit of sensitivity for deleting the unnecessary weights and other control methods during pruning and training are introduced. Thetraining course is analyzed theoretically and the reason why DOBD algorithm canobtain a much faster training speed than the OBD algorithm and avoid overfitting effectively is given.``

    2011-01-01

    Full Text Available This paper presents a stability analysis of train converters in order to evaluate how the controller parameters affect the absorbed current. The new dynamic model presented in this paper is capable of considering the time-variant nature of the system for the correct tuning of the feedback proportional-integral PI controller, applying a current controlled modulation technique never used in high-power traction converters. The reduction of the harmonic content of the current absorbed by a converter employed at the input stage onboard high-speed trains is really important, considering the interaction with the signaling system set up for traffic control. A computer model of the converter, considering both the power and the control structure, has also been implemented in order to deliver a validated tool for the developed theoretical analysis.

    2014-01-01

    Full Text Available Training overcomplete dictionary pair is a critical step of the mainstream superresolution methods. For the high time complexity and susceptible to corruption characteristics of training dictionary, an improved method based on lifting wavelet transform and robust principal component analysis is reported. The high-frequency components of example images are estimated through wavelet coefficients of 3-tier lifting wavelet transform decomposition. Sparse coefficients are similar in multiframe images. Accordingly, the inexact augmented Lagrange multiplier method is employed to achieve robust principal component analysis in the process of imposing global constraints. Experiments reveal that the new algorithm not only reduces the time complexity preserving the clarity but also improves the robustness for the corrupted example images.

    2016-10-01

    This article describes how we used a formative multi-method evaluation approach to gather real-time information about the processes of a complex, multi-day training with 24 community coalitions in the United States. The evaluation team used seven distinct, evaluation strategies to obtain evaluation data from the first Community Health Improvement Leadership Academy (CHILA) within a three-prong framework (inquiry, observation, and reflection). These methods included: comprehensive survey, rapid feedback form, learning wall, observational form, team debrief, social network analysis and critical moments reflection. The seven distinct methods allowed for both real time quality improvement during the CHILA and long term planning for the next CHILA. The methods also gave a comprehensive picture of the CHILA, which when synthesized allowed the evaluation team to assess the effectiveness of a training designed to tap into natural community strengths and accelerate health improvement. We hope that these formative evaluation methods can continue to be refined and used by others to evaluate training.

    Full Text Available Background: Health professionals play a key role in the delivery of nutrition interventions. Improving the quality of nutrition training in health professional schools is vital for building the necessary human resource capacity to implement effective interventions for reducing malnutrition in West Africa. This study was undertaken to assess the current status of nutrition training in medical, nursing and midwifery schools in West Africa. Design: Data were collected from 127 training programs organized by 52 medical, nursing, and midwifery schools. Using a semi-structured questionnaire, we collected information on the content and distribution of nutrition instruction throughout the curriculum, the number of hours devoted to nutrition, the years of the curriculum in which nutrition was taught, and the prevailing teaching methods. Simple descriptive and bivariate analyses were performed. Results: Nutrition instruction occurred mostly during the first 2 years for the nursing (84%, midwifery (87%, and nursing assistant (77% programs and clinical years in medical schools (64%. The total amount of time devoted to nutrition was on average 57, 56, 48, and 28 hours in the medical, nursing, midwifery, and nursing assistant programs, respectively. Nutrition instruction was mostly provided within the framework of a dedicated nutrition course in nursing (78%, midwifery (87%, and nursing assistant programs (100%, whereas it was mainly embedded in other courses in medical schools (46%. Training content was heavily weighted to basic nutrition in the nursing (69%, midwifery (77%, and nursing assistant (100% programs, while it was oriented toward clinical practice in the medical programs (64%. For all the programs, there was little focus (<6 hours contact time on public health nutrition. The teaching methods on nutrition training were mostly didactic in all the surveyed schools; however, we found an integrated model in some medical schools (12%. None of the

    This paper proposes an adaptive current control method for Hybrid Active Power Filter (HAPF). It consists of a fuzzy-neural controller, identification and prediction model and cost function. The fuzzy-neural controller parameters are adjusted according to the cost function minimum criteria. For this reason, the proposed control method has a capability on-line control clings to variation of the load harmonic currents. Compared to the single fuzzy logic control method, the proposed control method shows the advantages of better dynamic response, compensation error in steady-state is smaller, able to online control is better and harmonics cancelling is more effective. Simulation and experimental results have demonstrated the effectiveness of the proposed control method.

    The thermostimulated discharge current method (TSDC) is widely used for the study of charge storage mechanisms in electrets. A new discharged technique, called differential, which consists in discharging a charged sample through an otherwise identical but uncharged one, has been proposed by J.-P. Reboul and A. Toureille. In the present paper a new version of the differential thermostimulated discharge current method is advanced. In contrast to the differential technique described earlier, the measuring cell allows to realize typical differential technique. In this case the measuring system records the difference of the thermostimulated currents of two samples which have been preliminary charged (or thermally treated) under the same or different conditions. Samples of 0.85 mm thick polymethylmethacrylate are used to demonstrate an operation of the developed differential TSDC method.

    The purposes of this study were to identify current prosthodontic residents' demographics and to document prosthodontic residents' perspectives on their clinical training and future goals. A 52-item survey was created and distributed to prosthodontic residents in the United States on February 8, 2007. The data collected were analyzed; the means and standard deviations were calculated and ranked. Statistical analysis was conducted using Chi-square and Mann-Whitney analysis (p = 0.05). A 43% response rate was achieved, representing approximately 48% of the total population of prosthodontic residents in the United States. The majority of residents ranked clinical education as the most important factor in selecting their programs, were satisfied with their training, and planned to pursue the certification of the American Board of Prosthodontics. When asked how often they planned to work, 4 days a week was the most common answer. This is the first report identifying current prosthodontic residents' demographics and their perspectives on their clinical training and future goals. Several trends were identified, indicating a bright future for the specialty. By knowing the students' perceptions regarding their training and future goals, the American College of Prosthodontists and/or program directors will be able to use this information to improve residency programs and the specialty.

    Working memory (WM) is one of our core cognitive functions, allowing us to keep information in mind for shorter periods of time and then work with this information. It is the gateway that information has to pass in order to be processed consciously. A well-functioning WM is therefore crucial for a number of everyday activities including learning and academic performance (Gathercole et al., 2003; Bull et al., 2008), which is the focus of this review. Specifically, we will review the research investigating whether improving WM capacity using Cogmed WM training can lead to improvements on academic performance. Emphasis is given to reviewing the theoretical principles upon which such investigations rely, in particular the complex relation between WM and mathematical and reading abilities during development and how these are likely to be influenced by training. We suggest two possible routes in which training can influence academic performance, one through an effect on learning capacity which would thus be evident with time and education, and one through an immediate effect on performance on reading and mathematical tasks. Based on the theoretical complexity described we highlight some methodological issues that are important to take into consideration when designing and interpreting research on WM training and academic performance, but that are nonetheless often overlooked in the current research literature. Finally, we will provide some suggestions for future research for advancing the understanding of WM training and its potential role in supporting academic attainment.

  18. Probability of detection models for eddy current NDE methods

    Rajesh, S.N.

    1993-04-30

    The development of probability of detection (POD) models for a variety of nondestructive evaluation (NDE) methods is motivated by a desire to quantify the variability introduced during the process of testing. Sources of variability involved in eddy current methods of NDE include those caused by variations in liftoff, material properties, probe canting angle, scan format, surface roughness and measurement noise. This thesis presents a comprehensive POD model for eddy current NDE. Eddy current methods of nondestructive testing are used widely in industry to inspect a variety of nonferromagnetic and ferromagnetic materials. The development of a comprehensive POD model is therefore of significant importance. The model incorporates several sources of variability characterized by a multivariate Gaussian distribution and employs finite element analysis to predict the signal distribution. The method of mixtures is then used for estimating optimal threshold values. The research demonstrates the use of a finite element model within a probabilistic framework to the spread in the measured signal for eddy current nondestructive methods. Using the signal distributions for various flaw sizes the POD curves for varying defect parameters have been computed. In contrast to experimental POD models, the cost of generating such curves is very low and complex defect shapes can be handled very easily. The results are also operator independent.

    Although all authors report beneficial health changes following training based on the Pilates method, no explicit analysis has been performed of its cardiorespiratory effects. The objective of this study was to evaluate possible changes in cardiorespiratory parameters with the Pilates method. A total of 45 university students aged 18-35 years (77.8% female and 22.2% male), who did not routinely practice physical exercise or sports, volunteered for the study and signed informed consent. The Pilates training was conducted over 10 weeks, with three 1-hour sessions per week. Physiological cardiorespiratory responses were assessed using a MasterScreen CPX apparatus. After the 10-week training, statistically significant improvements were observed in mean heart rate (135.4-124.2 beats/min), respiratory exchange ratio (1.1-0.9) and oxygen equivalent (30.7-27.6) values, among other spirometric parameters, in submaximal aerobic testing. These findings indicate that practice of the Pilates method has a positive influence on cardiorespiratory parameters in healthy adults who do not routinely practice physical exercise activities.

    Full Text Available BACKGROUND: To achieve the best results in top volleyball it is necessary to analyze the current state and to react adequately to development trends, which characterize modern volleyball. OBJECTIVES: The goal of the study was to acquire information regarding how do top volleyball coaches of senior and junior volleyball teams in the Czech Republic put current knowledge and trends in volleyball sport training and coaching in practice. METHODS: We created a survey consisting of 31 questions, which were divided into 5 areas: respecting of the current requirements of game performance in training, training efficiency, conditioning, coaching and psycho-social aspects. The survey was sent to 49 coaches, 24 of them replied (response rate 49 %. RESULTS: The research shows that coaches do not apply all important knowledge and trends for players' preparation (76 % of correct answers in total. Groups of coaches were further divided to subgroups according to gender of the trained teams, age categories, coaches work load and 1st and 2nd class coaches. The comparison of the answers in the subgroup of coaches with respect to segregated areas has only pointed at a difference between male and female teams in the area of psycho-social training aspects (Z = 1.756; p = 0.079; d = 0.717. The comparison of coaches' groups answers to individual questions show that: a coaches of male teams base their training sessions on real game situations and choose the content of the exercises with the ball more thoroughly (Z = 1.85; p = 0.07; d = 0.75 and require defensive game combinations at the net more often (Z = 1.81; p = 0.07; d = 0.74; b junior teams are behind (Z = 1.90; p = 0.06; d = 0.77 senior teams in the number of training hours with the ball a week and in making conditions for successful realization of offensive game combinations with fast set (Z = 2.10; p = 0.04; d = 0.86; c 1st class coaches within the scope of condition training pay more attention to core training

    The electrostatic discharge (ESD) phenomenon is a great threat to all electronic devices and ICs. An electric charge passing rapidly from a charged body to another can seriously harm the last one. However, there is a lack in a linear mathematical approach which will make it possible to design a circuit capable of producing such a sophisticated current waveform. The commonly accepted electrostatic discharge current waveform is the one set by the IEC 61000-4-2. However, the over-simplified circuit included in the same standard is incapable of producing such a waveform. Treating the electrostatic discharge current waveform of the IEC 61000-4-2 as reference, an approximation method, based on Prony's method, is developed and applied in order to obtain a linear system's response. Considering a known input, a method to design a circuit, able to generate this ESD current waveform in presented. The circuit synthesis assumes ideal active elements. A simulation is carried out using the PSpice software. (authors)

  10. Effects of exercise training on chronic inflammation in obesity : current evidence and potential mechanisms.

    2013-04-01

    Chronic, systemic inflammation is an independent risk factor for several major clinical diseases. In obesity, circulating levels of inflammatory markers are elevated, possibly due to increased production of pro-inflammatory cytokines from several tissues/cells, including macrophages within adipose tissue, vascular endothelial cells and peripheral blood mononuclear cells. Recent evidence supports that adipose tissue hypoxia may be an important mechanism through which enlarged adipose tissue elicits local tissue inflammation and further contributes to systemic inflammation. Current evidence supports that exercise training, such as aerobic and resistance exercise, reduces chronic inflammation, especially in obese individuals with high levels of inflammatory biomarkers undergoing a longer-term intervention. Several studies have reported that this effect is independent of the exercise-induced weight loss. There are several mechanisms through which exercise training reduces chronic inflammation, including its effect on muscle tissue to generate muscle-derived, anti-inflammatory 'myokine', its effect on adipose tissue to improve hypoxia and reduce local adipose tissue inflammation, its effect on endothelial cells to reduce leukocyte adhesion and cytokine production systemically, and its effect on the immune system to lower the number of pro-inflammatory cells and reduce pro-inflammatory cytokine production per cell. Of these potential mechanisms, the effect of exercise training on adipose tissue oxygenation is worth further investigation, as it is very likely that exercise training stimulates adipose tissue angiogenesis and increases blood flow, thereby reducing hypoxia and the associated chronic inflammation in adipose tissue of obese individuals.

    Full Text Available We examined the effectiveness of a 2-week regimen of a semantic feature training in combination with transcranial direct current stimulation (tDCS for progressive naming impairment associated with primary progressive aphasia (N = 4 or early onset Alzheimer’s Disease (N = 1. Patients received a 2-week regimen (10 sessions of anodal tDCS delivered over the left temporoparietal cortex while completing a language therapy that consisted of repeated naming and semantic feature generation. Therapy targets consisted of familiar people, household items, clothes, foods, places, hygiene implements, and activities. Untrained items from each semantic category provided item level controls. We analyzed naming accuracies at multiple timepoints (i.e., pre-, post-, 6-month follow-up via a mixed effects logistic regression and individual differences in treatment responsiveness using a series of non-parametric McNemar tests. Patients showed advantages for naming trained over untrained items. These gains were evident immediately post tDCS. Trained items also showed a shallower rate of decline over 6-months relative to untrained items that showed continued progressive decline. Patients tolerated stimulation well, and sustained improvements in naming accuracy suggest that the current intervention approach is viable. Future implementation of a sham control condition will be crucial toward ascertaining whether neurostimulation and behavioral treatment act synergistically or alternatively whether treatment gains are exclusively attributable to either tDCS or the behavioral intervention.

    2016-01-01

    Full Text Available As more mission groups become involved with health care education, by starting medical and nursing schools, postgraduate training programs and paramedical professional training, there is a need to recruit expatriate faculty from high income countries to help start programs as there are few national health care education professionals available in the mission setting in most low- and middle-income countries. This paper outlines the current status and needs for academic faculty in health care education mission settings. A working group of medical educators met in conjunction with the Global Missions Health Conference in November 2015 and discussed the motivational factors which lead Christian academics to volunteer, both short- and long-term in mission settings. The group then looked at barriers to volunteering and made suggestions for future directions and best practices when mobilizing academics from high income countries.

  14. Study on Evaluation Methods for Lateral Stability of High-Speed Trains

    2012-01-01

    Taking a high-speed train in China as an example,using computer simulation technology and comparing with the test data,the three current methods including linear stability analysis method,nonlinear stability analysis method and the field testing criterion are studied to evaluate stability of high-speed trains.A new stability evaluation method is proposed which can be used to evaluate lateral stability of high-speed vehicle based on the codes of UIC 515 and UIC 518.From the viewpoint of taking the most unfavorable track conditions into account and improving the safety margin,the new method uses the root mean square of bogie lateral acceleration as a criterion to evaluate the lateral stability of high-speed trains.Numerical example shows that the proposed method not only considers the forced vibration caused by track irregularities in the actual practice,but also takes the instability self-excited vibration into account,so it can realize early warning of bogie slight unstable oscillation,meanwhile the method itself does not involve complex algorithms which has the possibility of engineering applications.

    Current issues in the use of peer assessment techniques and sociometric methods are discussed. Attention is paid to the contributions of the four articles in this volume. Together these contributions point to the continual level of change and progress in these techniques. They also show that the paradigm underlying these methods has been unchanged for decades. It is argued that this domain is ripe for a paradigm change that takes advantage of recent developments in statistical techniques and technology. © 2017 Wiley Periodicals, Inc.

  16. The current capacity for training in public health nutrition in West Africa.

    Pepping, Fré

    2010-01-01

    This article is based on a paper prepared for the Workshop on Establishing a Regional Institute for Public Health Nutrition Research and Training in West Africa, convened in Dakar, Senegal, 26-28 March, 2009. Information was gathered mainly prior to this workshop; several responses, however, came in after the workshop and these have been included in the current paper. In completion of the article use was made of the views and opinions as expressed during this workshop. Objectives were to provide background information on academic programmes (undergraduate and graduate) and research institutions with a focus on human nutrition in West Africa, to describe the importance of foreign nutrition training programmes for West African students and to detail existing nutrition training activities currently in the region. Data were obtained from a survey of 15 UNICEF country offices in the West African region, previously published reports, United Nations University/International Union of Nutrition Sciences capacity development activities 1996-2009, personal communications and websites of relevant African institutions. Results indicate that West African nutrition academic programmes and research institutes do not adequately meet the demand for nutritionists and technical services in the region. Exceptions seem to be Benin, Ghana and Nigeria. Diploma courses and other short courses have been an important means of attracting people from a variety of disciplines to nutrition. A well-equipped regional institute could directly and indirectly bolster nutrition capacity in the region. To meet the regional nutrition research and training needs in West Africa, it is not necessary to make a choice between creating a new regional institution vs. expanding existing national institutions. Based on solid capacity development principles, both options need action.

  17. German students' current choice of profession in the field of psychotherapy: Reasons for or against engaging in psychoanalytic training.

    Lebiger-Vogel, Judith

    2016-04-01

    The psychoanalytic societies in Germany as in many other countries are concerned by a decline in the number of candidates for full psychoanalytic training. While this situation is partly attributable to changes both in society and in educational and healthcare systems, it is questionable whether psychoanalytic training institutions have yet found adequate responses to it. Under the banner of 'evidence-based treatment', behaviour therapy has come to be widely disseminated, with major implications for the teaching of different psychotherapy paradigms at universities. To investigate the determinants of this trend in the specific German situation, a large-scale, multi-method exploratory study supported by IPA's DPPT programme was undertaken, focusing on the reasons given by a population (N = 679) of German psychology, medical, and education students for embarking on training in psychoanalysis or behaviour therapy. The results suggest that behaviour therapy is more compatible with the prevailing scientific understanding and with current societal and cultural trends, owing in part to inadequacies or bias in university teaching of the various paradigms of psychotherapy. While most of the psychology students expressed a preference for behavioural training, the psychotherapy option proved less attractive for their counterparts in the fields of medicine and education. Semi-standardized qualitative interviews were used to gain a deeper understanding of the students' decisions for or against training in a specific paradigm, and led to the identification of seven decision-making prototypes. Possible reasons for the students' decisions are discussed, and concrete proposals and recommendations are presented. Copyright © 2016 Institute of Psychoanalysis.

    Full Text Available Formal methods were developed to provide systematic and rigorous techniques for software development, and as initiative will be introduced in training in Software Engineering (SE. This article discusses the importance of including these scientific principles and describes several specific techniques in order to improve the processes of the IS. It also provides an analysis of the principles that should be taken into account in a curriculum to systematically introduce in university education and business. Several methods have been tried in recent years to achieve this goal in undergraduate and graduate universities programs, as well as IT professionals. Experience shows that participants gain confidence in formal methods only when they learn their clear benefits in the context of software engineering.

  20. Synthesis of unknowns for the interface partial current method

    Jatuff, F.E. [Investigacion Aplicada SE (INVAP), San Carlos de Bariloche (Argentina)

    1996-01-01

    A synthesis technique is formulated as an alternative for the standard solution of the low order Interface Partial Current Equations, common in the within-group iteration schemes of Nodal Expansion and Response Matrix methods. This non-linear technique represents each node (mesh) in the iterations by its total partial in-current (j{sup in}), instead of the K partial in-currents at the nodal faces. At the same time, the distribution vector f is introduced, whose elements are the fractions of j{sup in} entering through each face, which are assumed known from the previous fission-source iteration. This simple scheme, with no other non-linear feedback required, gives a nodal formulation of the inner problem with one unknown per node and energy group, while the problem still retains the original number of unknowns. The method has been tested on the IAEA-2D and -3D, and a 2D pressurized water reactor (Biblis) benchmarks. The results show savings of about 15% to 25% of the CPU time, identical convergence despite the irregular nodal discretizations, and compatability to the rest of the iteration strategy. (author).

    The risks of spreadsheet use do not just come from the misuse of formulae. As such, training needs to go beyond this technical aspect of spreadsheet use and look at the spreadsheet in its full business context. While standard training is by and large unable to do this, task-based training is perfectly suited to a contextual approach to training.

    Full Text Available Skill acquisition requires distributed learning both within (online and across (offline days to consolidate experiences into newly learned abilities. In particular, piloting an aircraft requires skills developed from extensive training and practice. Here, we tested the hypothesis that transcranial direct current stimulation (tDCS can modulate neuronal function to improve skill learning and performance during flight simulator training of aircraft landing procedures. Thirty-two right-handed participants consented to participate in four consecutive daily sessions of flight simulation training and received sham or anodal high-definition-tDCS to the right dorsolateral prefrontal cortex (DLPFC or left motor cortex (M1 in a randomized, double-blind experiment. Continuous electroencephalography (EEG and functional near infrared spectroscopy (fNIRS were collected during flight simulation, n-back working memory, and resting-state assessments. tDCS of the right DLPFC increased midline-frontal theta-band activity in flight and n-back working memory training, confirming tDCS-related modulation of brain processes involved in executive function. This modulation corresponded to a significantly different online and offline learning rates for working memory accuracy and decreased inter-subject behavioral variability in flight and n-back tasks in the DLPFC stimulation group. Additionally, tDCS of left M1 increased parietal alpha power during flight tasks and tDCS to the right DLPFC increased midline frontal theta-band power during n-back and flight tasks. These results demonstrate a modulation of group variance in skill acquisition through an increasing in learned skill consistency in cognitive and real-world tasks with tDCS. Further, tDCS performance improvements corresponded to changes in electrophysiological and blood-oxygenation activity of the DLPFC and motor cortices, providing a stronger link between modulated neuronal function and behavior.

  4. Cost-of-illness studies : a review of current methods.

    2006-01-01

    The number of cost-of-illness (COI) studies has expanded considerably over time. One outcome of this growth is that the reported COI estimates are inconsistent across studies, thereby raising concerns over the validity of the estimates and methods. Several factors have been identified in the literature as reasons for the observed variation in COI estimates. To date, the variation in the methods used to calculate costs has not been examined in great detail even though the variations in methods are a major driver of variation in COI estimates. The objective of this review was to document the variation in the methodologies employed in COI studies and to highlight the benefits and limitations of these methods. The review of COI studies was implemented following a four-step procedure: (i) a structured literature search of MEDLINE, JSTOR and EconLit; (ii) a review of abstracts using pre-defined inclusion and exclusion criteria; (iii) a full-text review using pre-defined inclusion and exclusion criteria; and (iv) classification of articles according to the methods used to calculate costs. This review identified four COI estimation methods (Sum_All Medical, Sum_Diagnosis Specific, Matched Control and Regression) that were used in categorising articles. Also, six components of direct medical costs and five components of indirect/non-medical costs were identified and used in categorising articles.365 full-length articles were reflected in the current review following the structured literature search. The top five cost components were emergency room/inpatient hospital costs, outpatient physician costs, drug costs, productivity losses and laboratory costs. The dominant method, Sum_Diagnosis Specific, was a total costing approach that restricted the summation of medical expenditures to those related to a diagnosis of the disease of interest. There was considerable variation in the methods used within disease subcategories. In several disease subcategories (e.g. asthma, dementia

    2013-07-01

    Photorespiration is a process that competes with photosynthesis, in which Rubisco oxygenates, instead of carboxylates, its substrate ribulose 1,5-bisphosphate. The photorespiratory metabolism associated with the recovery of 3-phosphoglycerate is energetically costly and results in the release of previously fixed CO2. The ability to quantify photorespiration is gaining importance as a tool to help improve plant productivity in order to meet the increasing global food demand. In recent years, substantial progress has been made in the methods used to measure photorespiration. Current techniques are able to measure multiple aspects of photorespiration at different points along the photorespiratory C2 cycle. Six different methods used to estimate photorespiration are reviewed, and their advantages and disadvantages discussed.

  6. Current Human Reliability Analysis Methods Applied to Computerized Procedures

    Energy Technology Data Exchange (ETDEWEB)

    Ronald L. Boring

    2012-06-01

    Computerized procedures (CPs) are an emerging technology within nuclear power plant control rooms. While CPs have been implemented internationally in advanced control rooms, to date no US nuclear power plant has implemented CPs in its main control room (Fink et al., 2009). Yet, CPs are a reality of new plant builds and are an area of considerable interest to existing plants, which see advantages in terms of enhanced ease of use and easier records management by omitting the need for updating hardcopy procedures. The overall intent of this paper is to provide a characterization of human reliability analysis (HRA) issues for computerized procedures. It is beyond the scope of this document to propose a new HRA approach or to recommend specific methods or refinements to those methods. Rather, this paper serves as a review of current HRA as it may be used for the analysis and review of computerized procedures.

    Radiology residents often teach medical students and other residents. Workshops developed with the goal of improving resident teaching skills are becoming increasingly common in various fields of medicine. The purpose of this study was to determine the prevalence and structure of resident-teacher training opportunities within radiology programs in the United States. Program directors with membership in the Association of Program Directors in Radiology (APDR) were surveyed to determine views on a panel of topics related to resident-teacher training programs. A total of 114 (56%) of 205 APDR members completed an online survey. Approximately one-third (32%) stated that their program provided instruction to residents on teaching skills. The majority of these programs (72%) were established within the last 5 years. Residents provided teaching to medical students (94%) and radiology residents (90%). The vast majority of program directors agreed that it is important for residents to teach (98%) and that these teaching experiences helped residents become better radiologists (85%). Ninety-four percent of program directors felt that the teaching skills of their residents could be improved, and 85% felt that residents would benefit from instruction on teaching methods. Only one-third of program directors felt their program adequately recognized teaching provided by residents. Program directors identified residents as being active contributors to teaching in most programs. Although teaching was viewed as an important skill to develop, few programs had instituted a resident-teacher curriculum. Program directors felt that residents would benefit from structured training to enhance teaching skills. Future studies are needed to determine how best to provide teaching skills training for radiology trainees. 2010 AUR. Published by Elsevier Inc. All rights reserved.

    The surgeon's formation process has changed in recent decades. The increase in medical schools, new specialties and modern technologies induce an overhaul of medical education. Medical residency in surgery has established itself as a key step in the formation of the surgeon, and represents the ideal and natural way for teaching laparoscopy. However, the introduction of laparoscopic surgery in the medical residency programs in surgical specialties is insufficient, creating the need for additional training after its termination. To review the surgical teaching ways used in services that published their results. Survey of relevant publications in books, internet and databases in PubMed, Lilacs and Scielo through july 2014 using the headings: laparoscopy; simulation; education, medical; learning; internship and residency. The training method for medical residency in surgery focused on surgical procedures in patients under supervision, has proven successful in the era of open surgery. However, conceptually turns as a process of experimentation in humans. Psychomotor learning must not be developed directly to the patient. Training in laparoscopic surgery requires the acquisition of psychomotor skills through training conducted initially with surgical simulation. Platforms based teaching problem solving as the Fundamentals of Laparoscopic Surgery, developed by the American Society of Gastrointestinal Endoscopic Surgery and the Laparoscopic Surgical Skills proposed by the European Society of Endoscopic Surgery has been widely used both for education and for the accreditation of surgeons worldwide. The establishment of a more appropriate pedagogical process for teaching laparoscopic surgery in the medical residency programs is mandatory in order to give a solid surgical education and to determine a structured and safe professional activity.

  12. A finite element method for analysis of vibration induced by maglev trains

    Science.gov (United States)

    Ju, S. H.; Ho, Y. S.; Leong, C. C.

    2012-07-01

    This paper developed a finite element method to perform the maglev train-bridge-soil interaction analysis with rail irregularities. An efficient proportional integral (PI) scheme with only a simple equation is used to control the force of the maglev wheel, which is modeled as a contact node moving along a number of target nodes. The moving maglev vehicles are modeled as a combination of spring-damper elements, lumped mass and rigid links. The Newmark method with the Newton-Raphson method is then used to solve the nonlinear dynamic equation. The major advantage is that all the proposed procedures are standard in the finite element method. The analytic solution of maglev vehicles passing a Timoshenko beam was used to validate the current finite element method with good agreements. Moreover, a very large-scale finite element analysis using the proposed scheme was also tested in this paper.

    Full Text Available Food losses due to crop infections from pathogens such as bacteria, viruses and fungi are persistent issues in agriculture for centuries across the globe. In order to minimize the disease induced damage in crops during growth, harvest and postharvest processing, as well as to maximize productivity and ensure agricultural sustainability, advanced disease detection and prevention in crops are imperative. This paper reviews the direct and indirect disease identification methods currently used in agriculture. Laboratory-based techniques such as polymerase chain reaction (PCR, immunofluorescence (IF, fluorescence in-situ hybridization (FISH, enzyme-linked immunosorbent assay (ELISA, flow cytometry (FCM and gas chromatography-mass spectrometry (GC-MS are some of the direct detection methods. Indirect methods include thermography, fluorescence imaging and hyperspectral techniques. Finally, the review also provides a comprehensive overview of biosensors based on highly selective bio-recognition elements such as enzyme, antibody, DNA/RNA and bacteriophage as a new tool for the early identification of crop diseases.

    The cerebellum is a key modulator of motor cortex activity, allowing both the maintenance and fine-tuning of motor cortex discharges. One elemental defect associated with acute cerebellar lesions is decreased excitability of the contralateral motor cortex, which is assumed to participate in deficits in skilled movements and considered a major defect in motor cortex properties. In the present study, the authors assessed the effect of trains of anodal transcranial direct current stimulation (tDCS), which elicits polarity-dependent shifts in resting membrane potentials. Transcranial DCS countered the defect in motor cortex excitability contralaterally to the hemicerebellar ablation. The depression of both the H-reflex and F wave remained unchanged with tDCS, and cutaneomuscular reflexes remained unaffected. Transcranial DCS antagonized motor cortex hypoexcitability induced by high-frequency stimulation of interpositus nucleus. The authors' results show that tDCS has the potential to modulate motor cortex excitability after acute cerebellar dysfunction. By putting the motor cortex at the appropriate level of excitability, tDCS might allow the motor cortex to become more reactive to the procedures of training or learning.

    Current teaching methods in graduate and postgraduate training often include frontal presentations. Especially in ultrasound education not only knowledge but also sensomotory and visual skills need to be taught. This requires new learning methods. This study examined which types of teaching methods are preferred by participants in ultrasound training courses before, during and after the course by analyzing a blended learning concept. It also investigated how much time trainees are willing to spend on such activities. A survey was conducted at the end of a certified ultrasound training course. Participants were asked to complete a questionnaire based on a visual analogue scale (VAS) in which three categories were defined: category (1) vote for acceptance with a two thirds majority (VAS 67-100%), category (2) simple acceptance (50-67%) and category (3) rejection (learning program with interactive elements, short presentations (less than 20 min), incorporating interaction with the audience, hands-on sessions in small groups, an alternation between presentations and hands-on-sessions, live demonstrations and quizzes. For post-course learning, interactive and media-assisted approaches were preferred, such as e-learning, films of the presentations and the possibility to stay in contact with instructors in order to discuss the results. Participants also voted for maintaining a logbook for documentation of results. The results of this study indicate the need for interactive learning concepts and blended learning activities. Directors of ultrasound courses may consider these aspects and are encouraged to develop sustainable learning pathways.

  19. Current Methods to Detoxify Fly Ash from Waste Incineration

    Fly ash from waste incineration contains large amounts of heavy metals and dioxins, which will cause a significant disposal problem within the coming years. The amount of fly ash produced in Sweden is currently approximately 60,000 tons/y. New technological options for the decontamination and/or inertization of incinerator fly ash are being developed with the objective of rendering a product that can be reused or, at least, be deposited at standard landfill sites with no risk. Many of these technologies have been tested at industrial scale or in pilot projects. The proposed alternatives include: Thermal treatments; Immobilization/stabilization by cement based techniques; Wet chemical treatments (extractions, immobilizations); Microbiological treatments. Of these, thermal treatments are the most promising solution. Depending on the temperature thermal treatments are classified in two main types: 1) low temperature (below 600 deg C) thermal treatments and 2) high temperature (above 1200 deg C) thermal treatments (vitrification). Most dioxins can be successfully destroyed at temperatures up to 400 deg C under oxygen deficient conditions and at temperatures up to 600 deg C under oxidising conditions. However most heavy metals remain in the fly ash after low temperature treatment. At a temperature of 900 deg C most heavy metals can also be removed in a 10% HCl atmosphere by forming volatile metal chlorides (CT-Fluapur process). During vitrification processes the fly ash melts and forms an inert glassy slag. The product does not leach any significant amount of heavy metals and is free from dioxin. The volume of the fly ash is significantly reduced. The product can be land filled at low costs or used as construction material. The properties of the product depend on the cooling process and on additives such as sand, limestone or waste glass. A series of vitrification methods at industrial size or in pilot scale using different furnaces are studied. Among these, plasma

    Genetically modified (GM) crops are the fastest adopted commodities in the agribiotech industry. This market penetration should provide a sustainable basis for ensuring food supply for growing global populations. The successful completion of two decades of commercial GM crop production (1996-2015) is underscored by the increasing rate of adoption of genetic engineering technology by farmers worldwide. With the advent of introduction of multiple traits stacked together in GM crops for combined herbicide tolerance, insect resistance, drought tolerance or disease resistance, the requirement of reliable and sensitive detection methods for tracing and labeling genetically modified organisms in the food/feed chain has become increasingly important. In addition, several countries have established threshold levels for GM content which trigger legally binding labeling schemes. The labeling of GM crops is mandatory in many countries (such as China, EU, Russia, Australia, New Zealand, Brazil, Israel, Saudi Arabia, Korea, Chile, Philippines, Indonesia, Thailand), whereas in Canada, Hong Kong, USA, South Africa, and Argentina voluntary labeling schemes operate. The rapid adoption of GM crops has increased controversies, and mitigating these issues pertaining to the implementation of effective regulatory measures for the detection of GM crops is essential. DNA-based detection methods have been successfully employed, while the whole genome sequencing using next-generation sequencing (NGS) technologies provides an advanced means for detecting genetically modified organisms and foods/feeds in GM crops. This review article describes the current status of GM crop commercialization and discusses the benefits and shortcomings of common and advanced detection systems for GMs in foods and animal feeds.

  7. Hypoxic training methods for improving endurance exercise performance

    Directory of Open Access Journals (Sweden)

    Jacob A. Sinex

    2015-12-01

    Full Text Available Endurance athletic performance is highly related to a number of factors that can be altered through altitude and hypoxic training including increases in erythrocyte volume, maximal aerobic exercise capacity, capillary density, and economy. Physiological adaptations in response to acute and chronic exposure to hypoxic environments are well documented and range from short-term detrimental effects to longer-term adaptations that can improve performance at altitude and in sea-level competitions. Many altitude and hypoxic training protocols have been developed, employing various combinations of living and training at sea-level, low, moderate, and high altitudes and utilizing natural and artificial altitudes, with varying degrees of effectiveness. Several factors have been identified that are associated with individual responses to hypoxic training, and techniques for identifying those athletes most likely to benefit from hypoxic training continue to be investigated. Exposure to sufficiently high altitude (2000–3000 m for more than 12 h/day, while training at lower altitudes, for a minimum of 21 days is recommended. Timing of altitude training related to competition remains under debate, although general recommendations can be considered.

    The purpose of this study was to assess the adequacy of current surgical residency and gastroenterology (GI) fellowship flexible endoscopy training as measured by performance on the FES examination. Fifth-year general surgery residents and GI fellows across six institutions were invited to participate. All general surgery residents had met ACGME/ABS case volume requirements as well as additional institution-specific requirements for endoscopy. All participants completed FES testing at the end of their respective academic year. Procedure volumes were obtained from ACGME case logs. Curricular components for each specialty and institution were recorded. Forty-eight (28 surgery and 20 GI) trainees completed the examination. Average case numbers for residents were 76 ± 26 colonoscopies and 45 ± 12 EGDs. Among GI fellows, PGY4 s (N = 10) reported 99 ± 64 colonoscopies and 147 ± 79 EGDs. PGY5 s (N = 3) reported 462 ± 307 colonoscopies and 411 ± 260 EGDs. PGY6 GI fellows (N = 7) reported 515 ± 111 colonoscopies and 418 ± 146 EGDs. The overall pass rate for all participants was 75 %, with 68 % of residents and 85 % of fellows passing both the cognitive and skills components. For surgery residents, pass rates were 75 % for manual skills and 85.7 % for cognitive. On the skills examination, Task 2 (loop reduction) was associated with the lowest performance. Skills scores correlated with both colonoscopy (r = 0.46, p < 0.001) and EGD experience (r = 0.46, p < 0.001). Receiver operating characteristics curves were examined among the resident cohort. The minimum number of total cases associated with passing the FES skills component was 103. Significant variability existed in curricular components across institutions. These data suggest that current flexible endoscopy training may not be sufficient for all trainees to pass the examination. Implementing additional components of the FEC may prove beneficial in achieving more uniform pass

    The aim of the present study was to analyse the training load in wheelchair basketball small-sided games and determine the relationship between heart rate (HR)-based training load and perceived exertion (RPE)-based training load methods among small-sided games bouts. HR-based measurements of training load included Edwards' training load and Stagno's training impulses (TRIMPMOD) while RPE-based training load measurements included cardiopulmonary (session RPEres) and muscular (session RPEmus) values. Data were collected from 12 wheelchair basketball players during five consecutive weeks. The total load for the small-sided games sessions was 67.5 ± 6.7 and 55.3 ± 12.5 AU in HR-based training load (Edwards' training load and TRIMPMOD), while the RPE-based training loads were 99.3 ± 26.9 (session RPEres) and 100.8 ± 31.2 AU (session RPEmus). Bout-to-bout analysis identified greater session RPEmus in the third [P training loads. It is suggested that HR-based and RPE-based training loads provide different information, but these two methods could be complementary because one method could help us to understand the limitations of the other.

    Full Text Available The study aims to validate that a smartphone application can assist in the learning and skills retention for cardiopulmonary resuscitation training. This cardiopulmonary resuscitation feature of the Crowdsav platform is designed to record the chest compression performance as well as the rate of compressions of the trainee. Crowdsav is available for downloading in the public domain. The application, once downloaded can be utilised during training and be replayed by the trainee at his/her own will or via reminders from the training centre. The goal of using this application is to minimise the decay of the knowledge and compression skills and perhaps even reduce the resource for recertification, as skills and performance can be kept up, maintained and monitored remotely by a training centre using the application.

    2008-08-01

    Laparoscopic surgery is now an integral technique in the practice of urology, particularly in the management of certain urologic malignancies. Advanced laparoscopy training in urology is primarily reserved for those pursuing fellowship training and is offered both by traditional endourology fellowships and increasingly in urologic oncology fellowships. The purpose of our study was to evaluate and compare current laparoscopy training at the fellowship level. A 17-item questionnaire was developed with support from both the Endourological Society (EUS) and Society of Urologic Oncology (SUO). Surveys were sent to program directors of fellowships recognized by the EUS and SUO. Directors were surveyed on the laparoscopic case volume, degree of oncology training, and career choice of their graduates. Data were analyzed with Wilcoxon rank-sum and Student t tests. Our survey had an overall response rate of 60%. Fellows performed more than 100 laparoscopies during their training period in 57% of EUS and 25% of SUO fellowship programs. Similar trends are demonstrated when analyzing robotic procedures, with 73% of EUS fellows performing more than 50 procedures compared with 43% of SUO fellows. The majority (59%) of EUS programs provide oncologic training. Between 44% and 100% of graduates from EUS and SUO fellowships obtain academic positions. The majority of SUO directors (63%) believe that fellowship training in laparoscopy should be provided in fellowships governed solely by the SUO, while 41% of EUS directors believe this training should be governed solely by the EUS. Endourology fellowships currently provide a greater exposure to laparoscopy and robotics than SUO fellowships. The percentage of fellows seeking academic positions is similar for EUS and SUO fellowship programs and has remained stable for several years. Directors of fellowship programs that offer advanced laparoscopic training have divergent views as to which administrative body should govern its future.

    The purpose of this study was to determine the level of knowledge that current and preservice high school (HS) physical educators and sport coaches possess regarding the principles and methods involved in youth resistance training (RT) and to determine if that knowledge was acceptable based on a predetermined criterion (passing score). A panel of 10 experts in RT or sport pedagogy used a Delphi technique to create a 90-question assessment (examination) that was administered to 287 HS physical educators and sport coaches and 140 university physical education teacher education (PETE) students. An analysis of the results revealed that neither group demonstrated the minimal knowledge necessary to design, implement, and supervise RT programs based on a passing score of 75%: HS physical educators/coaches, mean = 59.30, SD = 14.30, 95% confidence interval (CI) = 57.64-60.96], t(286) = -18.61, p = 0.000; university PETE students, mean = 56.61, SD = 16.59, 95% CI = 53.84-59.38, t(139) = -13.12, p = 0.000. The pass rate for physical educators and sport coaches was 14.3% and for university PETE students it was 20.7%. The results of this study indicate that both current and preservice physical educators and sport coaches need additional education and training specific to the design and implementation of RT programs for HS students. Given that school districts typically require their educators attend in-service training programs, it may be advisable to develop an in-service program that allows both current and preservice HS physical educators and sport coaches to earn an RT certification that specifically addresses the unique physical and psychosocial needs of school-aged youth.

    Goodman-Deane, Joy; Ward, James; Hosking, Ian; Clarkson, P John

    2014-07-01

    Inclusive design has unique challenges because it aims to improve usability for a wide range of users. This typically includes people with lower levels of ability, as well as mainstream users. This paper examines the effectiveness of two methods that are used in inclusive design: user trials and exclusion calculations (an inclusive design inspection method). A study examined three autoinjectors using both methods (n=30 for the user trials). The usability issues identified by each method are compared and the effectiveness of the methods is discussed. The study found that each method identified different kinds of issues, all of which are important for inclusive design. We therefore conclude that a combination of methods should be used in inclusive design rather than relying on a single method. Recommendations are also given for how the individual methods can be used more effectively in this context.

  19. A neural network driving curve generation method for the heavy-haul train

    Directory of Open Access Journals (Sweden)

    Youneng Huang

    2016-05-01

    Full Text Available The heavy-haul train has a series of characteristics, such as the locomotive traction properties, the longer length of train, and the nonlinear train pipe pressure during train braking. When the train is running on a continuous long and steep downgrade railway line, the safety of the train is ensured by cycle braking, which puts high demands on the driving skills of the driver. In this article, a driving curve generation method for the heavy-haul train based on a neural network is proposed. First, in order to describe the nonlinear characteristics of train braking, the neural network model is constructed and trained by practical driving data. In the neural network model, various nonlinear neurons are interconnected to work for information processing and transmission. The target value of train braking pressure reduction and release time is achieved by modeling the braking process. The equation of train motion is computed to obtain the driving curve. Finally, in four typical operation scenarios, comparing the curve data generated by the method with corresponding practical data of the Shuohuang heavy-haul railway line, the results show that the method is effective.

    Most assessments of the quality of postgraduate training are based on anonymised questionnaires of trainees. We report a comprehensive assessment of the quality of training at a large postgraduate psychiatry training institute using non-anonymised face-to-face interviews with trainees and their trainers. Two consultant psychiatrists interviewed 99 trainees and 109 trainers. Scoring of interview responses was determined by using a pre-defined criteria. Additional comments were recorded as free text. Interviews covered 13 domains, including: Clinical, teaching, research and management opportunities, clinical environment, clinical supervision, adequacy of job description, absence of bullying and job satisfaction. Multiple interview domain scores were combined, generating a 'Combined' score for each post. The interview response rate was 97% for trainers 88% for trainees. There was a significant correlation between trainee and trainer scores for the same interview domains (Pearson's r = 0.968, pJob satisfaction scores of year 1 to year 3 core trainees showed a significant increase with increasing seniority (Linear regression coefficient = 0.273, 95% CI: 0.033 to 0.513, ANOVA p= 0.026). This in-depth examination of the quality of training on a large psychiatry training programme successfully elicited strengths and weakness of our programme. Such an interview scheme could be easily implemented in smaller schemes and may well provide important information to allow for targeted improvement of training. Additionally, trends in quality of training and job satisfaction amongst various psychiatric specialities were identified; specifically speciality posts and liaison posts in psychiatry were revealed to be the most popular with trainees.

    Rumpf, MC, Lockie, RG, Cronin, JB, and Jalilvand, F. Effect of different sprint training methods on sprint performance over various distances: a brief review. J Strength Cond Res 30(6): 1767-1785, 2016-Linear sprinting speed is an essential physical quality for many athletes. There are a number of different training modalities that can be used to improve sprint performance. Strength and conditioning coaches must select the most appropriate modalities for their athletes, taking into consideration the sprint distances that typically occur during competition. The study purpose was to perform a brief review as to the effect of specific (free sprinting; resisted sprinting by sleds, bands, or incline running; assisted sprinting with a towing device or a downhill slope), nonspecific (resistance and plyometric training), and combined (a combination of specific and nonspecific) training methods on different sprint distances (0-10, 0-20, 0-30, and 31+ m). A total of 48 studies fulfilled the inclusion criteria, resulting in 1,485 subjects from a range of athletic backgrounds. The training effects associated with specific sprint training were classified as moderate (effect size [ES] = -1.00; %change = -3.23). Generally, the effect of specific sprint training tended to decrease with distance, although the largest training effects were observed for the 31+ m distance. The greatest training effects (ES = -0.43; %change = -1.65) of nonspecific training were observed for the 31+ m distance. The combined training revealed greatest effects (ES = -0.59; %change = -2.81) for the 0-10 m distance. After this review, specific sprint training methods seem the most beneficial over the investigated distances. However, the implementation of nonspecific training methods (e.g., strength and power training) could also benefit speed and athletic performance.

    This paper introduces a novel hybrid FEM-BEM method for calculating 3D eddy current field. In the eddy current region, the eddy current density J is solved by the finite element method (FEM) which is discretized by brick finite element mesh, while in the eddy current free region, the magnetic field intensity H is solved by the boundary element method (BEM) which is discretized by rectangular boundary element mesh. Under the boundary conditions, an algebraic equation group is obtained that only includes J by eliminating H. This method has many advantages over traditional ones, such as fewer variables, more convenient coupling between the FEM and the BEM and wider application to multiply-connected regions. The calculated values of two models are in good agreement with experimental results. This shows the validity of our method.

    Primary progressive aphasia (PPA) is an untreatable neurodegenerative disorder that disrupts language functions. Previous studies have demonstrated transcranial direct current stimulation (tDCS) may improve language symptoms in patients with post stroke aphasia or neurodegenerative diseases. The present study investigated whether the application of anodal tDCS (AtDCS) to the scalp overlying the left dorsolateral prefrontal cortex (DLPFC), which may increase cortical excitability, in combination with individualized speech therapy would improve naming accuracy in the agrammatic variant of PPA (avPPA). Sixteen avPPA patients were randomly allocated into two subgroups: AtDCS (n = 8) or placebo tDCS (PtDCS). tDCS was applied over the left DLPFC (BA 8/9) 25 minutes per day for two weeks (10 days). Each patient underwent 25 minutes of individualized speech therapy with either AtDCS or PtDCS during each treatment session. Neuropsychological assessment, experimental naming, and linguistic abilities in daily living were assessed at baseline (T0), after two weeks of intervention (T1) and at a 12-week follow-up (T2). Significant improvement in experimental naming was observed in both groups at T1 and T2, but this effect was significantly greater in AtDCS than PtDCS patients. Naming correctness, as assessed using the Aachener Aphasie Test, increased selectively in the AtDCS group from T0 to T1, and this effect remained significant at T2. The analysis of daily living language abilities improved selectively in AtDCS group. Our results support the beneficial effect of targeted language training in combination with brain stimulation in avPPA patients. tDCS should be considered a useful tool for the improvement of language functions in patients with neurodegenerative diseases in future trials.

    This double-blind, sham-controlled, crossover case study combined transvertebral direct current stimulation (tvDCS) and locomotor training on a robot-assisted gait orthosis (LT-RGO). Determine whether cathodal tvDCS paired with LT-RGO leads to greater changes in function and neuroplasticity than sham tvDCS paired with LT-RGO. University of Kentucky (UK) HealthCare Stroke and Spinal Cord Neurorehabilitation Research at HealthSouth Cardinal Hill Hospital. A single subject with motor incomplete spinal cord injury (SCI) participated in 24 sessions of sham tvDCS paired with LT-RGO before crossover to 24 sessions of cathodal tvDCS paired with LT-RGO. Functional outcomes were measured with 10 Meter Walk Test (10MWT), 6 Minute Walk Test (6MWT), Spinal Cord Independence Measure-III (SCIM-III) mobility component, lower extremity manual muscle test (MMT), and Berg Balance Scale (BBS). Corticospinal changes were assessed using transcranial magnetic stimulation. Improvement in 10MWT speed, SCIM-III mobility component, and BBS occurred with both conditions. 6MWT worsened after sham tvDCS and improved after cathodal tvDCS. MMT scores for both lower extremities improved following sham tvDCS but decreased following cathodal tvDCS. Corticospinal excitability increased following cathodal tvDCS but not sham tvDCS. These results suggest that combining cathodal tvDCS and LT-RGO may improve functional outcomes, increase corticospinal excitability, and possibly decrease spasticity. Randomized controlled trials are needed to confirm these conclusions.

    To investigate the effects of combination cathodal transcranial direct current stimulation (tDCS) and virtual reality (VR) therapy for upper extremity (UE) training in patients with subacute stroke. Pilot randomized controlled trial. Patients were randomly assigned to 1 of 3 groups: group A received cathodal tDCS, group B received VR, and group C received combination therapy (cathodal tDCS was simultaneously applied during VR therapy). University hospital. Patients (N=59) with impaired unilateral UE motor function after stroke. Fifteen sessions of treatment over a 3-week period. The Modified Ashworth Scale, manual muscle test (MMT), Manual Function Test (MFT), Fugl-Meyer Scale (FMS), and Box and Block Test were used to assess UE function. To evaluate activities of daily living, the Korean-Modified Barthel Index (K-MBI) was used. All outcomes were measured before and immediately after treatment. After treatment, all groups demonstrated significant improvements in MMT, MFT, FMS, and K-MBI scores. The change in MFT and FMS scores was different between the 3 groups. Post hoc analysis revealed that the improvement of MFT and FMS scores in group C was significantly higher than those of the other 2 groups. In the present pilot study, the combination of brain stimulation using tDCS and peripheral arm training using VR could facilitate a stronger beneficial effect on UE impairment than using each intervention alone. This combination therapy might be a helpful method to enhance recovery of the paretic UE in patients with stroke. Copyright © 2014 American Congress of Rehabilitation Medicine.

  2. A Correlation Based Method for Discriminating Inrush Current from Short Circuit Current Using Wavelet Transform in Power Transformer Differential Protection

    Directory of Open Access Journals (Sweden)

    M. Rasoulpoor

    2013-09-01

    Full Text Available This paper presents a new approach for power transformer differential protection. The Wavelet Transform is applied to discriminate between inrush currents and internal fault currents in power transformers. Discrete wavelet transform decomposes the current signal into sub-bands that give more information about the properties of the signals in different frequency bands. Also, this transform is used to investigate the energy distribution of the signal on the different time and frequency scales. Recognition method is based on the correlation factors between energy percentage vectors of the Wavelet coefficients. Discrete Wavelet transform is used for decomposing the current signals to different frequency coefficients. After that, by constituting the energy percentage vectors of wavelet transform coefficients and calculating the correlation factors between these vectors, it is possible to form a recognition criterion to distinguish between inrush and internal fault current in the proposed method. The proposed algorithm is tested for several conditions by simulated inrush and internal fault currents. Simulation of current signals is performed using electromagnetic transient program PSCAD/EMTDC software that is a powerful program for the investigation of transient signals. Simulation results show that the proposed scheme accurately identifies inrush and fault currents in the distance of the power transformer protection in less than quarter of power frequency cycle. Also, beside the sensitivity and high reliability, the proposed method has low computation content and unlike the common methods does not require to determine the threshold for each new power system.

    Full Text Available Propositions necessary for development of parallel-hierarchical (PH network training methods are discussed in this article. Unlike already known structures of the artificial neural network, where non-normalized (absolute similarity criteria are used for comparison, the suggested structure uses a normalized criterion. Based on the analysis of training rules, a conclusion is made that application of two training methods with a teacher is optimal for PH network training: error correction-based training and memory-based training. Mathematical models of training and a combined method of PH network training for recognition of static and dynamic patterns are developed.

    An intervention study was conducted to examine the effectiveness of an innovative self-modeling photo-training method for reducing musculoskeletal risk among office workers using computers. Sixty workers were randomly assigned to either: 1) a control group; 2) an office training group that received personal, ergonomic training and workstation adjustments or 3) a photo-training group that received both office training and an automatic frequent-feedback system that displayed on the computer screen a photo of the worker's current sitting posture together with the correct posture photo taken earlier during office training. Musculoskeletal risk was evaluated using the Rapid Upper Limb Assessment (RULA) method before, during and after the six weeks intervention. Both training methods provided effective short-term posture improvement; however, sustained improvement was only attained with the photo-training method. Both interventions had a greater effect on older workers and on workers suffering more musculoskeletal pain. The photo-training method had a greater positive effect on women than on men.

    2016-11-01

    The objective of this review is to summarize the contribution of animal research using direct current stimulation (DCS) to our understanding of the physiological effects of transcranial direct current stimulation (tDCS). We comprehensively address experimental methodology in animal studies, broadly classified as: (1) transcranial stimulation; (2) direct cortical stimulation in vivo and (3) in vitro models. In each case advantages and disadvantages for translational research are discussed including dose translation and the overarching "quasi-uniform" assumption, which underpins translational relevance in all animal models of tDCS. Terminology such as anode, cathode, inward current, outward current, current density, electric field, and uniform are defined. Though we put key animal experiments spanning decades in perspective, our goal is not simply an exhaustive cataloging of relevant animal studies, but rather to put them in context of ongoing efforts to improve tDCS. Cellular targets, including excitatory neuronal somas, dendrites, axons, interneurons, glial cells, and endothelial cells are considered. We emphasize neurons are always depolarized and hyperpolarized such that effects of DCS on neuronal excitability can only be evaluated within subcellular regions of the neuron. Findings from animal studies on the effects of DCS on plasticity (LTP/LTD) and network oscillations are reviewed extensively. Any endogenous phenomena dependent on membrane potential changes are, in theory, susceptible to modulation by DCS. The relevance of morphological changes (galvanotropy) to tDCS is also considered, as we suggest microscopic migration of axon terminals or dendritic spines may be relevant during tDCS. A majority of clinical studies using tDCS employ a simplistic dose strategy where excitability is singularly increased or decreased under the anode and cathode, respectively. We discuss how this strategy, itself based on classic animal studies, cannot account for the

    A range of communication skills training programmes have been developed targeting trainees in various medical specialties, predominantly in oncology but to a lesser extent in psychiatry. Effective communication is fundamental to the assessment and treatment of psychiatric conditions, but there has been less attention to this in clinical practice for psychiatrists in training. This review examines the outcomes of communication skills training interventions in psychiatric specialty training. The published English-language literature was examined using multiple online databases, grey literature and hand searches. The review was conducted and reported using Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Studies examining the efficacy of communication skills training were included. Randomised controlled trials, pseudo-randomised studies and quasi-experimental studies, as well as observational analytical studies and qualitative studies that met criteria, were selected and critically appraised. No limits were applied for date of publication up until 16 July 2016. Total search results yielded 2574 records. Of these, 12 studies were identified and reviewed. Two were randomised controlled trials and the remaining 10 were one-group pretest/posttest designs or posttest-only designs, including self-report evaluations of communication skills training and objective evaluations of trainee skills. There were no studies with outcomes related to behaviour change or patient outcomes. Two randomised controlled trials reported an improvement in clinician empathy and psychotherapeutic interviewing skills due to specific training protocols focused on those areas. Non-randomised studies showed varying levels of skills gains and self-reported trainee satisfaction ratings with programmes, with the intervention being some form of communication skills training. The heterogeneity of communication skills training is a barrier to evaluating the efficacy of

    2002-08-01

    Bulk RE-Ba-Cu-O (RE: rare earth elements) superconductors exhibit high critical current density ( Jc) and low thermal conductivity, that are the characteristics desired for the current lead applications. In this study, we studied whether the resin-impregnated Y-Ba-Cu-O rods can be used as the current lead for the superconducting magnet on a magnetically levitated train. The fatigue test showed that the mechanical properties of resin-impregnated Y-Ba-Cu-O rods are sufficiently good for maglev applications. We could also pass the electric currents of 500 A without heat generation. This was further confirmed by field distribution measurements, which showed that the superconducting state of the current lead was well maintained when the currents of 500 A were passed.

    In 1999, the Charité Medical University in Berlin, Germany, implemented a reformed medical study course (RMSC) along with traditional undergraduate medical education. The RMSC is characterized by problem-based learning (PBL), training in communication skills with "simulated patients", and interdisciplinary seminars. The curriculum is organized into blocks according to organ system and age (period od life). In a new intensive 4-week psychiatric block, 4th-year students get practical experience in psychiatric wards. Furthermore, PBL groups and workshops are offered that focus on frequent psychiatric disorders. By providing interactive courses with simulated patients, students are intensively trained in taking psychiatric histories and in generating psychopathological findings. Defined learning objectives are tested using multiple-choice items and objectively structured clinical examinations at semester end. First positive results indicate that this course represents an appropriate and practicable curriculum for teaching psychiatry in Germany.

  17. Part-task training in the context of automation: current and future directions.

    Science.gov (United States)

    Gutzwiller, Robert S; Clegg, Benjamin A; Blitch, John G

    2013-01-01

    Automation often elicits a divide-and-conquer outlook. By definition, automation has been suggested to assume control over a part or whole task that was previously performed by a human (Parasuraman & Riley, 1997). When such notions of automation are taken as grounds for training, they readily invoke a part-task training (PTT) approach. This article outlines broad functions of automation as a source of PTT and reviews the PTT literature, focusing on the potential benefits and costs related to using automation as a mechanism for PTT. The article reviews some past work in this area and suggests a path to move beyond the type of work captured by the "automation as PTT" framework. An illustrative experiment shows how automation in training and PTT are actually separable issues. PTT with automation has some utility but ultimately remains an unsatisfactory framework for the future broad potential of automation during training, and we suggest that a new conceptualization is needed.

    Statistical methods are frequently used in toxicology, yet it is not clear whether the methods employed by the studies are used consistently and conducted based on sound statistical grounds. The purpose of this paper is to describe statistical methods used in top toxicology journals. More specifically, we sampled 30 papers published in 2014 from Toxicology and Applied Pharmacology, Archives of Toxicology, and Toxicological Science and described methodologies used to provide descriptive and inferential statistics. One hundred thirteen endpoints were observed in those 30 papers, and most studies had sample size less than 10, with the median and the mode being 6 and 3 & 6, respectively. Mean (105/113, 93%) was dominantly used to measure central tendency, and standard error of the mean (64/113, 57%) and standard deviation (39/113, 34%) were used to measure dispersion, while few studies provide justifications regarding why the methods being selected. Inferential statistics were frequently conducted (93/113, 82%), with one-way ANOVA being most popular (52/93, 56%), yet few studies conducted either normality or equal variance test. These results suggest that more consistent and appropriate use of statistical method is necessary which may enhance the role of toxicology in public health.

  20. Building Visual Artists’ Resilience Capabilities: Current Educator Strategies and Methods

    Full Text Available Enrolments in higher education programs in the creative and performing arts are increasing in many countries. Yet graduates of these degrees, who enter the broad sector known as the creative industries, face particular challenges in terms of securing long-term and sustainable employment. In addition, creative and performing artists face a range of mental challenges, caused by such factors as: the solitary nature of much creative practice, critical feedback by audiences and gatekeepers, or the general pressures associated with maintaining artistic relevance or integrity. The concepts of resilience and professional wellbeing are therefore highly relevant to those who pursue a career in creative industries, and while there has been an emerging body of work in this area, to date it has focussed on the performing arts area (e.g. music, theatre. Hence, in order to expand knowledge relevant to resilience and artists, this paper sets out to explore the extent to which current educators in the Australian context specifically address these issues within higher visual arts curricula; specifically the areas of illustration, design, film and photography. This was achieved via interviews with seventeen current academics working in these areas. The findings propose that higher education providers of programs in the visual arts consider placing a stronger emphasis on the embedded development of resilience and professional wellbeing capacities.

    Full Text Available Heart failure commonly results from an irreparable damage due to cardiovascular diseases (CVDs, the leading cause of morbidity and mortality in the United States. In recent years, the rapid advancements in stem cell research have garnered much praise for paving the way to novel therapies in reversing myocardial injuries. Cell types currently investigated for cellular delivery include embryonic stem cells (ESCs, induced pluripotent stem cells (iPSCs, and adult stem cell lineages such as skeletal myoblasts, bone-marrow-derived stem cells (BMSCs, mesenchymal stem cells (MSCs, and cardiac stem cells (CSCs. To engraft these cells into patients’ damaged myocardium, a variety of approaches (intramyocardial, transendocardial, transcoronary, venous, intravenous, intracoronary artery and retrograde venous administrations and bioengineered tissue transplantation have been developed and explored. In this paper, we will discuss the pros and cons of these delivery modalities, the current state of their therapeutic potentials, and a multifaceted evaluation of their reported clinical feasibility, safety, and efficacy. While the issues of optimal delivery approach, the best progenitor stem cell type, the most effective dose, and timing of administration remain to be addressed, we are highly optimistic that stem cell therapy will provide a clinically viable option for myocardial regeneration.

    The significance is evaluated of nuclear methods for agricultural research. The number of breeds induced by radiation mutations is increasing. The main importance of radiation mutation breeding consists in obtaining sources of the desired genetic properties for further hybridization. Radiostimulation is conducted with the aim of increasing yields. The irradiation of foods has not substantially increased worldwide. Very important is the irradiation of excrements and sludges which after such inactivation of pathogenic microorganisms may be used as humus-forming manure or as feed additives. In some countries the method is successfully being used of sexual sterilization for eradication of insect pests. The application of labelled compounds in the nutrition, physiology and protection of plants, farm animals and in food hygiene makes it possible to acquire new and accurate knowledge very quickly. Radioimmunoassay is a highly promising method in this respect. Labelling compounds with the stable /sup 15/N isotope is used for the research of nitrogen metabolism.

    Dry skin is a frequent problem in dermatology and a sign of dysfunction of the epidermis, especially of the stratum corneum as the morphological equivalent of the skin barrier. It may occur as an individual disposition or as the leading symptom of atopic dermatitis or ichthyosis. Besides the visual examination of the skin, various bioengineering methods have been developed to assess the different pathological and adaptive changes in the skin. In addition to the assessment of skin humidity, barrier function and desquamation, the quantification of skin surface topography and the mechanical properties of skin are suitable methods to characterize a dry skin condition. For clinical assessment of moisturizing products and emollients the parameters of investigation have to be defined and integrated in an adapted study design depending on the composition and content of the active agent in the test product. Newly developed cosmetic products have to be investigated for safety and efficacy. Modern bioengineering methods are suitable to fulfill these challenges.

    Scuro, S. J.

    1986-05-01

    An axial-type homopolar motor having high density, high current fiber brush collectors affording efficient, low contact resistance and low operating temperatures is discussed. The collectors include a ring of concentric row of brushes in equally spaced beveled holes soldered in place using a fixture for heating the ring to just below the solder melting point at a soldering iron for the local application of additional heat at each brush. Prior to soldering, an oxide film is formed on the surfaces of the brushes and ring, and the bevels are burnished to form a wetting surface. Flux applied with the solder at each bevel removes to an effective soldering depth the oxide film on the brushes and the holes.

    The detection of early forms of keratoconus is still a challenge for clinicians. Beside clinical examination and diagnosis of keratoconus, a series of examination techniques has been established in clinical routine to assist in the diagnosis of early forms of keratoconus: corneal topography for measuring the geometry of the corneal front surface, tomography for measuring the geometry of structures of the anterior segment of the eye, aberrometers for evaluation of optical aberrations of the entire eye, and a system for investigation of the biomechanical properties of the cornea. These instruments provide software tools which are designed for diagnostic support in keratoconus. In this review article, we provide an overview over the spectrum of measurement systems currently on the market focussing on their performance for detecting (early forms of) keratoconus. In detail, we focus on dedicated keratoconus screening software modules of topography, tomography, aberrometry and biomechanics.

    2015-09-01

    Electric brake systems are used in high-speed trains to brake trains by converting the kinetic energy of a railway vehicle to electric energy. The electric brake system consists of a regenerative braking system and a dynamic braking system. When the electric energy generated during the dynamic braking process is changed to heat through the braking resistor, the braking resistor can overheat; thus, failures can occur to the motor block. In this paper, a braking resistor for a high-speed train was used to perform thermal analyses and tests, and the results were analyzed. The analyzed data were used to estimate the dependence of the brake currents and the temperature rises on speed changes up to 300 km/h, at which a test could not be performed.

    2016-03-01

    The declining number of physician scientists is an alarming issue. A systematic review of all existing programs described in the literature was performed, so as to highlight which programs may serve as the best models for the training of successful physician scientists. Multiple databases were searched, and 1,294 articles related to physician scientist training were identified. Preference was given to studies that looked at number of confirmed publications and/or research grants as primary outcomes. Thirteen programs were identified in nine studies. Eighty-three percent of Medical Scientist Training Program (MSTP) graduates, 77% of Clinician Investigator Training Program (CI) graduates, and only 16% of Medical Fellows Program graduates entered a career in academics. Seventy-eight percent of MSTP graduates succeeded in obtaining National Institute of Health (NIH) grants, while only 15% of Mayo Clinic National Research Service Award-T32 graduates obtained NIH grants. MSTP physician scientists who graduated in 1990 had 13.5 ± 12.5 publications, while MSTP physician scientists who graduated in 1975 had 51.2 ± 38.3 publications. Additionally, graduates from the Mayo Clinic's MD-PhD Program, the CI Program, and the NSRA Program had 18.2 ± 20.1, 26.5 ± 24.5, and 17.9 ± 26.3 publications, respectively. MSTP is a successful model for the training of physician scientists in the United States, but training at the postgraduate level also shows promising outcomes. An increase in the number of positions available for training at the postgraduate level should be considered.

    The increasing use of `new methods' in NLP, which the NeMLaP conference series exemplifies, occurs in the context of a wider shift in the nature and concerns of the discipline. This paper begins with a short review of this context and significant trends in the field. The review motivates and leads to a set of requirements for support software of general utility for NLP research and development workers. A freely-available system designed to meet these requirements is described (called GATE - a General Architecture for Text Engineering). Information Extraction (IE), in the sense defined by the Message Understanding Conferences (ARPA \\cite{Arp95}), is an NLP application in which many of the new methods have found a home (Hobbs \\cite{Hob93}; Jacobs ed. purposes, and this is described. Lastly we review related work.

    Currently, the only standardized evaluation of trauma knowledge throughout orthopedic training is found in the Orthopaedic In-Training Examination, which is administered annually to all residents by the American Academy of Orthopaedic Surgeons. Our goals were to assess the Orthopaedic In-Training Examination to (1) determine the content of the trauma questions, (2) identify the content of the 3 most frequently referenced journals on the answer keys, and (3) evaluate the correlation between those contents.We reviewed the trauma-related Orthopaedic In-Training Examination questions and answer keys for 2002 through 2007. Content for test questions and cited literature was assessed with the same criteria: (1) category type, (2) anatomic location, (3) orthopedic focus, and (4) treatment type. For each of the 3 most frequently referenced journals, we weighted content by dividing the number of times it was referenced by the number of its trauma-related articles. We then compared the journal data individually and collectively to the data from the Orthopaedic In-Training Examination trauma questions. A chi-square analysis with Yates correction was used to determine differences. Questions and literature were similar in the most frequently addressed items in each of the 4 areas: category type (taxonomy 3, treatment), 52.4% and 60.7%, respectively; anatomic location (femur), 23.3% and 27.7%, respectively; orthopedic focus (fracture), 51.0% and 56.5%, respectively; and treatment type (multiple/nonspecific), 39.0% and 35.4%, respectively.The content correlation found between the questions and literature supports the idea that reviewing current literature may help prepare for the trauma content on the Orthopaedic In-Training Examination.

    2009-03-01

    Increasing international travel and migration have contributed to globalization of diseases. Physicians today must understand the global burden and epidemiology of diseases, the disparities and inequities in global health systems, and the importance of cross-cultural sensitivity. To meet these needs, resident physicians across all specialties have expressed growing interest in global health training and international clinical rotations. More residents are acquiring international experience, despite inadequate guidance and support from most accreditation organizations and residency programs. Surveys of global health training, including international clinical rotations, highlight the benefits of global health training as well as the need for a more coordinated approach. In particular, international rotations broaden a resident's medical knowledge, reinforce physical examination skills, and encourage practicing medicine among underserved and multicultural populations. As residents recognize these personal and professional benefits, a strong majority of them seek to gain international clinical experience. In conclusion, with feasible and appropriate administrative steps, all residents can receive global health training and be afforded the accreditation and programmatic support to participate in safe international rotations. The next steps should address accreditation for international rotations and allowance for training away from continuity clinics by residency accreditation bodies, and stipend and travel support for six or more weeks of call-free elective time from residency programs.

    To characterize the training of Community Health Workers in the field of child hearing health. A systematic literature review on Biblioteca Virtual em Saúde (BVS) and Biblioteca Digital de Teses e Dissertações of USP databases was performed. The search strategy was oriented by the specific question: "How have the Community Health Workers been trained to work in the field of child hearing health?" The study selection criteria involved consistency with the proposed theme, belonging to the category of scientific papers, dissertation or thesis, and publication in Brazilian Portuguese. A total of 2,687 studies were found. After analyzing the title and abstract, eight studies were chosen for full reading, however, only four of them met the proposed criteria and were included in the review. The studies indicated live and virtual classes with the use of video conferencing or CD-ROM as training strategies for Community Health Workers. Trainings were effective. Only one questionnaire about hearing and language monitoring was described. Different possibilities for the activities of Community Health Workers were identified. Different learning methodologies have been used for training the Community Health Worker in the field of child hearing health, and all of have proven effective for knowledge acquisition. Community Health Workers play an important role in promoting and monitoring child hearing health.

  3. Flaws in current human training protocols for spontaneous Brain-Computer Interfaces: lessons learned from instructional design

    Directory of Open Access Journals (Sweden)

    Fabien eLotte

    2013-09-01

    Full Text Available While recent research on Brain-Computer Interfaces (BCI has highlighted their potential for many applications, they remain barely used outside laboratories. The main reason is their lack of robustness. Indeed, with current BCI, mental state recognition is usually slow and often incorrect. Spontaneous BCI (i.e., mental imagery-based BCI often rely on mutual learning efforts by the user and the machine, with BCI users learning to produce stable EEG patterns (spontaneous BCI control being widely acknowledged as a skill while the computer learns to automatically recognize these EEG patterns, using signal processing. Most research so far was focused on signal processing, mostly neglecting the human in the loop. However, how well the user masters the BCI skill is also a key element explaining BCI robustness. Indeed, if the user is not able to produce stable and distinct EEG patterns, then no signal processing algorithm would be able to recognize them. Unfortunately, despite the importance of BCI training protocols, they have been scarcely studied so far, and used mostly unchanged for years.In this paper, we advocate that current human training approaches for spontaneous BCI are most likely inappropriate. We notably study instructional design literature in order to identify the key requirements and guidelines for a successful training procedure that promotes a good and efficient skill learning. This literature study highlights that current spontaneous BCI user training procedures satisfy very few of these requirements and hence are likely to be suboptimal. We therefore identify the flaws in BCI training protocols according to instructional design principles, at several levels: in the instructions provided to the user, in the tasks he/she has to perform, and in the feedback provided. For each level, we propose new research directions that are theoretically expected to address some of these flaws and to help users learn the BCI skill more efficiently.

    A specialized conditioning protocol for honeybees that is designed for use within a complex agricultural ecosystem. This method ensures that the conditioned bees will be less likely to exhibit a conditioned response to uninfected plants, a false positive response that would render such a biological sensor unreliable for agricultural decision support. Also described is a superboosting training regime that allows training without the aid of expensive equipment and protocols for training in out in the field. Also described is a memory enhancing cocktail that aids in long term memory retention of a vapor signature. This allows the bees to be used in the field for longer durations and with fewer bees trained overall.

    We report the results of a social validity assessment that was administered to special education service providers (N = 44) to document the acceptability and effectiveness ratings of several treatment integrity training methods. The participants judged performance feedback as the most likely method to improve their treatment integrity, followed by avoidance (negative reinforcement) of supervision meetings, online training, and financial incentive. Performance feedback was also rank-ordered as most effective among the four training methods. We discuss the merits of social validity assessment in designing programs for enhancing treatment integrity among practitioners within educational and clinical settings.

    This study investigated the perspectives of foreign-trained dentists (FTDs) in comparison with US-trained Dentists (USTDs) in Advanced Education in Prosthodontics (AEP) programs on their current clinical training and future goals. This study was conducted by analyzing data from previously published literature. When appropriate, Chi-square statistical analysis was conducted to determine the influence of where the AEP residents earned their DMD/DDS degree (FTDs/USTDs) on all variables. Only results that yielded significant differences were discussed. A majority of both FTDs and USTDs were male. Most USTDs were married, while most FTDs were single. Most FTDs were not US citizens and most originated from Asia, followed by the Middle East, South America, and Europe. Significantly more FTDs had higher ranks in their dental schools, had more advanced degrees, and spent more time practicing before entering the AEP programs. In selecting AEP programs, FTDs placed significantly higher values on a program's reputation and research opportunities. During their AEP training, FTDs paid significantly higher tuition and received lower stipends, but obtained more financial support from families. On the other hand, USTDs received significantly more financial aid and earned income from part-time work, but had significantly higher total educational debts. USTDs showed a significantly higher interest in becoming a student member of the American College of Prosthodontists and participated actively in prosthodontics organizations. USTDs were more interested in becoming maxillofacial prosthodontists, while FTDs were more interested in pursuing academic careers. FTDs differed from USTDs in several ways. Because of their interests in academics and research, FTDs may potentially have a positive impact on the development of the prosthodontics discipline. This information may be beneficial for AEP program directors in accommodating the needs of FTDs, and for FTDs in better preparing for their

    Rotary-wing computational fluid dynamics is reaching a point where many three-dimensional, unsteady, finite-difference codes are becoming available. This paper gives a brief review of five such codes, which treat the small disturbance, conservative and nonconservative full-potential, and Euler flow models. A discussion of the methods of applying these codes to the rotor environment (including wake and trim considerations) is followed by a comparison with various available data. These data include tests of advancing lifting and nonlifting, and hovering model rotors with significant supercritical flow regions. The codes are also compared for computational efficiency.

It is a common and the most important process in the formation and development of blood vessels, so it is supportive in the healing of wounds and granulation of tissues. The different assays for the evaluation of angiogenesis have been described with distinct advantages and some limitations. In order to develop angiogenic and antiangiogenic techniques, continuous efforts have been resulted to give animal models for more quantitative analysis of angiogenesis. Most of the studies on angiogenic inducers and inhibitors rely on various models, both in vitro, in vivo and in ova, as indicators of efficacy. The angiogenesis assays are very much helpful to test efficacy of both pro- and anti- angiogenic agents. The development of non-invasive procedures for quantification of angiogenesis will facilitate this process significantly. The main objective of this review article is to focus on the novel and existing methods of angiogenesis and their quantification techniques. These findings will be helpful to establish the most convenient methods for the detection, quantification of angiogenesis and to develop a novel, well tolerated and cost effective anti-angiogenic treatment in the near future.

    2011-01-01

    Full Text Available Drug resistance is the main cause of the failure of chemotherapy of malignant tumors, resistance being either preexisting (intrinsic resistance or induced by the drugs (acquired resistance. At present, resistance is usually diagnosed during treatment after a long period of drug administration.In the present paper, methods for a rapid assessment of drug resistance are described. Three main classes of test procedures can be found in the literature, i.e. fresh tumor cell culture tests, cancer biomarker tests and positron emission tomography (PET tests. The methods are based on the evaluation of molecular processes, i.e. metabolic activities of cancer cells. Drug resistance can be diagnosed before treatment in-vitro with fresh tumor cell culture tests, and after a short time of treatment in-vivo with PET tests. Cancer biomarker tests, for which great potential has been predicted, are largely still in the development stage. Individual resistance surveillance with tests delivering rapid results signifies progress in cancer therapy management, by providing the possibility to avoid drug therapies that are ineffective and only harmful.

    To evaluate the level of compliance with the official curriculum residence programme by geriatrics trainees, and to analyse their level of satisfaction. A questionnaire was developed including these sections: trainee filiation, and questions related to their clinical training, academic formation, research training, satisfaction, and other comments. The survey was performed in Survey Monkey and sent to a geriatric trainee per hospital in March 2014. The results were collected between March and April of 2014. Responses were received from 41% of the trainees of 23 Geriatric Teaching Units. Rates of over 95% were observed as regards clinical rotations in the basic period, while in the specific period these percentages varied between 34% and 69%, probably because some of the trainees had not yet arrived at the period in which these rotations are programmed. An external rotation could be performed by 83% of the trainees, and 90% do the recommended number of shifts. The mean number of instruction sessions per week was 2.3, and the number of meetings with the tutor was 2.5 times per year. The median number of presentations in congresses was 3.7 per trainee, with 0.2 publications during training. Each trainee attended 1.2 national meetings, 0.3 European meetings, and 0.1 American. Most of the trainees (85%) were satisfied or very satisfied with their training. Geriatrics curricula for trainees are followed in the basic aspects, but not so much in the specific ones. The average level satisfaction of the trainees is very high. The recommended training activities within the specific department (sessions, etc.) are not always fulfilled. The research activity, evaluated by publications and presentations at meetings, is low. Following these data, reflection and the establishment of improvements are required in Geriatrics training at post-graduate level. Copyright © 2014 SEGG. Published by Elsevier Espana.

    Full Text Available Aim: This study was conducted to assess the risk of fracture in postmenopausal women using dual x-ray absorptiometry bone mineral density (DEXA-BMD as a reference method and FRAX as a new clinical risk assessment tool. Material and Method: 168 postmenopausal women (> 50 years evaluating with DEXA-BMD and FRAX methods were included in the study. Femoral BMD (F-BMD, femoral T-score (F-Ts, lumbar spine BMD (L-BMD and lumbar spine T-score (L-Ts values of the patients were calculated. Fracture risk assessments were carried out using T-score values and FRAX 10-year hip fracture (HF and major osteoporotic fracture (MOF risk ratios. Data were analyzed statistically. Results: According to the results of F-Ts and L-Ts, 44/168 (26.2% and 65/168 (38.7% of patients had osteoporosis as compatible with high fracture risk. In osteoporotic patients, mean values for F-Ts L-Ts, F-BMD and L-BMD were -2.8 ± 0.4, -3.2 ± 0.5, 0.530 ± 0.049 and 0.682 ± 0.066, respectively. There were found to be high MOF risk in 16/168 (9.5% and high HF risk in 51/168 (30.4% of patients according to FRAX. Positive correlations were determined between F-Ts and L-Ts (moderate; rho = 0.424, p <0.05 and between HF and MOF (strong; rho = 0.958, p <0001. There were strong negative correlations among HF and MOF with F-Ts (respectively, rho = -0.897 and rho = -0.844, p <0.001 and moderate negative correlations among HF and MOF with L-Ts (respectively, rho = -0.535 and rho = - 0.567, p <0.05. Discussion: In postmenopausal women with osteoporosis, risk assessment by the FRAX besides the DXA-BMD measurements can be useful for not to be missed of patients with high risk of fracture.

    Full Text Available The problem of permanent vocational training is important in sustaining thevocational conversion of the working class. A change of views and mentality isdesirable regarding vocational training, in the sense that people need to be moreaware of the importance of permanent learning, more motivated in order tobroaden their horizon and more willing to develop their professional skills. Thelabour market in Romania has suffered important changes due to the economictransition process, which has been materialized especially on the level ofreducing the number of active workers and of employees, thus maintaining arelatively constant rate of unemployment and affecting the labour marketingespecially by a limited number of jobs.

    Full Text Available Hysterectomy is the commonest gynecologic operation performed not only for malignant disease but also for many benign conditions such as fibroids, endometrial hyperplasia, adenomyosis, uterine prolapse, dysfunctional uterine bleeding, and cervical intraepithelial neoplasia. There are many approaches to hysterectomy for benign disease: abdominal hysterectomy, vaginal hysterectomy, laparoscopic assisted vaginal hysterectomy (LAVH where a vaginal hysterectomy is assisted by laparoscopic procedures that do not include uterine artery ligation, total laparoscopic hysterectomy (TLH where the laparoscopic procedures include uterine artery ligation, and subtotal laparoscopic hysterectomy (STLH where there is no vaginal component and the uterine body is removed using a morcelator. In the last decades, many new techniques, alternative to hysterectomy with conservation of the uterus have been developed. They use modern technologies and their results are promising and in many cases comparable with hysterectomy. This paper is a review of all the existing hysterectomy techniques and the alternative methods for benign indications.

    Full Text Available BACKGROUND: Cerebral palsy refers to permanent, mutable motor development disorders stemming from a primary brain lesion, causing secondary musculoskeletal problems and limitations in activities of daily living. The aim of the present study was to determine the effects of gait training combined with transcranial direct-current stimulation over the primary motor cortex on balance and functional performance in children with cerebral palsy. METHODS: A double-blind randomized controlled study was carried out with 24 children aged five to 12 years with cerebral palsy randomly allocated to two intervention groups (blocks of six and stratified based on GMFCS level (levels I-II or level III.The experimental group (12 children was submitted to treadmill training and anodal stimulation of the primary motor cortex. The control group (12 children was submitted to treadmill training and placebo transcranial direct-current stimulation. Training was performed in five weekly sessions for 2 weeks. Evaluations consisted of stabilometric analysis as well as the administration of the Pediatric Balance Scale and Pediatric Evaluation of Disability Inventory one week before the intervention, one week after the completion of the intervention and one month after the completion of the intervention. All patients and two examiners were blinded to the allocation of the children to the different groups. RESULTS: The experimental group exhibited better results in comparison to the control group with regard to anteroposterior sway (eyes open and closed; p<0.05, mediolateral sway (eyes closed; p<0.05 and the Pediatric Balance Scale both one week and one month after the completion of the protocol. CONCLUSION: Gait training on a treadmill combined with anodal stimulation of the primary motor cortex led to improvements in static balance and functional performance in children with cerebral palsy.

    . These papers used 128 statistical terms and context-defined concepts, including some from data analysis (56), epidemiology-biostatistics (31), modeling (24), data collection (12), and meta-analysis (5). Ten different software programs were used in these articles. Based on usual undergraduate and graduate statistics curricula, 64.3% of the concepts and methods used in these papers required at least a master's degree-level statistics education. The interpretation of the current medical literature can require an extensive background in statistical methods at an education level exceeding the material and resources provided to most medical students and residents. Given the complexity and time pressure of medical education, these deficiencies will be hard to correct, but this project can serve as a basis for developing a curriculum in study design and statistical methods needed by physicians-in-training.

  17. Inspiratory muscle training is used in some intensive care units, but many training methods have uncertain efficacy: a survey of French physiotherapists

    Full Text Available Questions: How common is inspiratory muscle training by physiotherapists in the intensive care unit (ICU? Which patients receive the training? What methods are used to administer the training? Is maximal inspiratory pressure used to evaluate the need for the training and the patient's outcome after training? Design: Cross-sectional survey of all ICUs in France. Participants: Two hundred and sixty-five senior physiotherapists. Results: The response rate was 99% among eligible units. Therapist experience in ICU was significantly associated with the use of inspiratory muscle training (p = 0.02. Therapists mainly used inspiratory muscle training either systematically or specifically in patients who failed to wean from mechanical ventilation. The training was used significantly more in non-sedated patients (p < 0.0001. The most commonly nominated technique that respondents claimed to use to apply the training was controlled diaphragmatic breathing (83% of respondents, whereas 13% used evidence-based methods. Among those who applied some form of inspiratory muscle training, 16% assessed maximal inspiratory pressure. Six respondents (2%, 95% CI 1 to 5 used both an evidence-based method to administer inspiratory muscle training and the recommended technique for assessment of inspiratory muscle strength. Conclusion: Most physiotherapists in French ICUs who apply inspiratory muscle training use methods of uncertain efficacy without assessment of maximal inspiratory pressure. Further efforts need to be made in France to disseminate information regarding evidence-based assessment and techniques for inspiratory muscle training in the ICU. The alignment of inspiratory muscle training practice with evidence could be investigated in other regions.

  1. The Current and Future Role of Heart Rate Variability for Assessing and Training Compassion

    Science.gov (United States)

    2017-01-01

    The evolution of mammalian caregiving involving hormones, such as oxytocin, vasopressin, and the myelinated vagal nerve as part of the ventral parasympathetic system, enables humans to connect, co-regulate each other’s emotions and create prosociality. Compassion-based interventions draw upon a number of specific exercises and strategies to stimulate these physiological processes and create conditions of “interpersonal safeness,” thereby helping people engage with, alleviate, and prevent suffering. Hence, compassion-based approaches are connected with our evolved caring motivation and attachment and our general affiliative systems that help regulate distress. Physiologically, they are connected to activity of the vagus nerve and corresponding adaptive heart rate variability (HRV). HRV is an important physiological marker for overall health, and the body–mind connection. Therefore, there is significant value of training compassion to increase HRV and training HRV to facilitate compassion. Despite the significance of compassion in alleviating and preventing suffering, there remain difficulties in its precise assessment. HRV offers a useful form of measurement to assess and train compassion. Specific examples of what exercises can facilitate HRV and how to measure HRV will be described. This paper argues that the field of compassion science needs to move toward including HRV as a primary outcome measure in its future assessment and training, due to its connection to vagal regulatory activity, and its link to overall health and well-being.

    2015-01-01

    Full Text Available A fault tree is established based on structural analysis, working principle analysis, and failure mode and effects analysis (FMEA of the pantograph-type current collector on the Chinese Rail High-Speed Electric Multiple Unit (CRH EMU train. To avoid the deficiencies of fault tree analysis (FTA, Petri nets modelling is used to address the problem of data explosion and carry out dynamic diagnosis. Relational matrix analysis is used to solve the minimal cut set equation of the fault tree. Based on the established state equation of the Petri nets, initial tokens and enable-transfer algorithms are used to express the fault transfer process mathematically and improve the efficiency of fault diagnosis inferences. Finally, using a practical fault diagnosis example for the pantographs on CRH EMU trains, the proposed method is proved to be reasonable and effective.

    Simulated/standardized patient-based (SP) education and problem-based learning (PBL) tutorial education become a powerful tool to heighten the pharmacy students' will to learn in order to cultivate the responsibility to contribute to public health and welfare as a clinical professional and to facilitate students' competences to solve problems by themselves. What this program is trying to do is: 1) to establish the system to train, educate and supply SP who are effective in the training and education of pharmacy students in close cooperation with the medical schools and their affiliated hospitals; 2) to improve the quality of the current PBL tutorial education and thereby establish it as an advanced education program in the education of senior students. We carried out the questionnaire to National University Corporation which establishes a school of pharmacy, as to the training and education of SP. The analysis of the answers to the questionnaire revealed the present status of SP in the Pharmaceutical Objective Structured Clinical Examination (OSCE) in the Pharmaceutical Common Achievement Test, and the existence of the problems on how to standardize SP as well as how to cover such expenses. Furthermore, the activity of the first year consisted of the exchange and sharing of information regarding the existing method of training and education of SP and PBL tutorial education and the identification of the problems to be solved in order to improve the quality of the educational program.

    The determination of the mass and the width of the Z boson at CERN's LEP accelerator, an e+e- storage ring with a circumference of approximately 27 kilometres, imposes heavy demands on the knowledge of the LEP counter-rotating electron and positron beam energies. The precision required is of the order of 1 MeV or »20 ppm frequency. Due to its size the LEP collider is influenced by various macroscopic and regional factors such as the position of the moon or seasonal changes of the rainfall in the area, as reported earlier. A new and not less surprising effect of the LEP energy was observed in 1995: railroad trains in the Geneva region perturb the dipole field. A parasitic flow of electricity, originating from the trains, travels along the LEP ground cable and the vacuum chamber, interacting with the dipole field. An account of the phenomenon with its explanation substantiated by dedicated measurements is presented.

As such, it is important for nurse practitioners, often the primary providers for rural and disadvantaged populations, to develop the knowledge, skills, and attitudes needed to utilize telehealth technologies in practice. In reviewing the literature, very little information was found on programs that addressed nurse practitioner training in telehealth. This article provides an overview of both the topics and the techniques that have been utilized for training nurse practitioners and nurse practitioner students in the delivery of care utilizing telehealth. Specifically, this article focuses on topics including 1 defining telehealth, 2 telehealth etiquette, 3 interprofessional collaboration, 4 regulations, 5 reimbursement, 6 security/Health Insurance Portability and Accountability Act (HIPAA, 7 ethical practice in telehealth, and 8 satisfaction of patients and providers. A multimodal approach based on a review of the literature is presented for providing the training: 1 didactics, 2 simulations including standardized patient encounters, 3 practice immersions, and 4 telehealth projects. Studies found that training using the multimodal approach allowed the students to develop comfort, knowledge, and skills needed to embrace the utilization of telehealth in health care.

  15. Simultaneously Excitatory and Inhibitory Effects of Transcranial Alternating Current Stimulation Revealed Using Selective Pulse-Train Stimulation in the Rat Motor Cortex.

    2017-09-27

    Transcranial alternating current stimulation (tACS) uses sinusoidal, subthreshold, electric fields to modulate cortical processing. Cortical processing depends on a fine balance between excitation and inhibition and tACS acts on both excitatory and inhibitory cortical neurons. Given this, it is not clear whether tACS should increase or decrease cortical excitability. We investigated this using transcranial current stimulation of the rat (all males) motor cortex consisting of a continuous subthreshold sine wave with short bursts of suprathreshold pulse-trains inserted at different phases to probe cortical excitability. We found that when a low-rate, long-duration, suprathreshold pulse-train was used, subthreshold cathodal tACS decreased cortical excitability and anodal tACS increased excitability. However, when a high-rate, short-duration, suprathreshold pulse-train was used this pattern was inverted. An integrate-and-fire model incorporating biophysical differences between cortical excitatory and inhibitory neurons could predict the experimental data and helped interpret these results. The model indicated that low-rate suprathreshold pulse-trains preferentially stimulate excitatory cortical neurons, whereas high-rate suprathreshold pulse-trains stimulate both excitatory and inhibitory neurons. If correct, this indicates that suprathreshold pulse-train stimulation may be able to selectively control the excitation-inhibition balance within a cortical network. The excitation-inhibition balance then likely plays an important role in determining whether subthreshold tACS will increase or decrease cortical excitability.SIGNIFICANCE STATEMENT Transcranial alternating current stimulation (tACS) is a noninvasive neuromodulation method that uses weak sinusoidal electric fields to modulate cortical activity. In healthy volunteers tACS can modulate perception, cognition, and motor function but the underlying neural mechanism is poorly understood. In this study, using rat motor

    A data object is constructed from a P by M Wurfelspiel matrix W by choosing an entry from each column to construct a sequence A0A1"AM-1. Each of the PM possibilities are designed to correspond to the same category according to some chosen measure. This matrix could encode many types of data. (1) Musical fragments, all of which evoke sadness; each column entry is a 4 beat sequence with a chosen A0A1A2 thus 16 beats long (W is P by 3). (2) Paintings, all of which evoke happiness; each column entry is a layer and a given A0A1A2 is a painting constructed using these layers (W is P by 3). (3) abstract feature vectors corresponding to action potentials evoked from a biological cell's exposure to a toxin. The action potential is divided into four relevant regions and each column entry represents the feature vector of a region. A given A0A1A2 is then an abstraction of the excitable cell's output (W is P by 4). (4) abstract feature vectors corresponding to an object such as a face or vehicle. The object is divided into four categories each assigned an abstract feature vector with the resulting concatenation an abstract representation of the object (W is P by 4). All of the examples above correspond to one particular measure (sad music, happy paintings, an introduced toxin, an object to recognize)and hence, when a Wurfelspiel matrix is constructed, relevant training information for recognition is encoded that can be used in many algorithms. The focus of this paper is on the application of these ideas to automatic target recognition (ATR). In addition, we discuss a larger biologically based model of temporal cortex polymodal sensor fusion which can use the feature vectors extracted from the ATR Wurfelspiel data.

    Since 2002 NOAA National Weather Service (NWS) Climate Services Division (CSD) offered training opportunities to NWS staff. As a result of eight-year-long development of the training program, NWS offers three training courses and about 25 online distance learning modules covering various climate topics: climate data and observations, climate variability and change, NWS national and local climate products, their tools, skill, and interpretation. Leveraging climate information and expertise available at all NOAA line offices and partners allows delivery of the most advanced knowledge and is a very critical aspect of the training program. NWS challenges in providing local climate services includes effective communication techniques on provide highly technical scientific information to local users. Addressing this challenge requires well trained, climate-literate workforce at local level capable of communicating the NOAA climate products and services as well as provide climate-sensitive decision support. Trained NWS climate service personnel use proactive and reactive approaches and professional education methods in communicating climate variability and change information to local users. Both scientifically-unimpaired messages and amiable communication techniques such as story telling approach are important in developing an engaged dialog between the climate service providers and users. Several pilot projects NWS CSD conducted in the past year applied the NWS climate services training program to training events for NOAA technical user groups. The technical user groups included natural resources managers, engineers, hydrologists, and planners for transportation infrastructure. Training of professional user groups required tailoring the instructions to the potential applications of each group of users. Training technical user identified the following critical issues: (1) Knowledge of target audience expectations, initial knowledge status, and potential use of climate

    In this paper, the authors propose a new identification method of the magnetizing inrush current phenomena. In general, the identification is done using with current waveform. However, the saturation of current transformer can't give waveform. Therefore, the authors introduce the identification method using with voltage waveform, in which the saturation of voltage transformer doesn't happen. And then, applying the Aitken's Δ2-process, it is showed that the new identification method gives the exact saturation on/off time.

    Due to the small size of training sets, statistical shape models often over-constrain the deformation in medical image segmentation. Hence, artificial enlargement of the training set has been proposed as a solution for the problem to increase the flexibility of the models. In this paper, different methods were evaluated to artificially enlarge a training set. Furthermore, the objectives were to study the effects of the size of the training set, to estimate the optimal number of deformation modes, to study the effects of different error sources, and to compare different deformation methods. The study was performed for a cardiac shape model consisting of ventricles, atria, and epicardium, and built from magnetic resonance (MR) volume images of 25 subjects. Both shape modeling and image segmentation accuracies were studied. The objectives were reached by utilizing different training sets and datasets, and two deformation methods. The evaluation proved that artificial enlargement of the training set improves both the modeling and segmentation accuracy. All but one enlargement techniques gave statistically significantly (p < 0.05) better segmentation results than the standard method without enlargement. The two best enlargement techniques were the nonrigid movement technique and the technique that combines principal component analysis (PCA) and finite element model (FEM). The optimal number of deformation modes was found to be near 100 modes in our application. The active shape model segmentation gave better segmentation accuracy than the one based on the simulated annealing optimization of the model weights.

    Building research capacity is a central component of many contemporary global health programs and partnerships. While medical anthropologists have been conducting qualitative research in resource-poor settings for decades, they are increasingly called on to train "local" clinicians, researchers, and students in qualitative research methods. In this article, I describe the process of teaching introductory courses in qualitative research methods to Haitian clinicians, hospital staff, and medical students, who rarely encounter qualitative research in their training or practice. These trainings allow participants to identify and begin to address challenges related to health services delivery, quality of care, and provider-patient relations. However, they also run the risk of perpetuating colonial legacies of objectification and reinforcing hierarchies of knowledge and knowledge production. As these trainings increase in number and scope, they offer the opportunity to reflect critically on new forms of transnational interventions that aim to reduce health disparities.

  10. Skeletal Muscle Function Deficits in the Elderly: Current Perspectives on Resistance Training

    Papa, Evan V.; Dong, Xiaoyang; Hassan, Mahdi

    2017-01-01

    A variety of changes in skeletal muscle occur with aging. Sarcopenia is the age-associated loss of muscle mass and is one of the main contributors to musculoskeletal impairments in the elderly. Traditional definitions of sarcopenia focused on the size of human skeletal muscle. However, increasing evidence in older adults suggests that low muscle mass is associated with weakness, and weakness is strongly associated with function and disability. In recent years a global trend has shifted toward more encompassing definitions for the loss of muscle mass which include decreases in physical function. This review focuses on skeletal muscle function deficits in the elderly and how these age-associated deficits can be ameliorated by resistance training. We set forth evidence that skeletal muscle deficits arise from changes within the muscle, including reduced fiber size, decreased satellite cell and fiber numbers, and decreased expression of myosin heavy chain (MHC) isoform IIa. Finally, we provide recommendations for clinical geriatric practice regarding how resistance training can attenuate the increase in age-associated skeletal muscle function deficits. Practitioners should consider encouraging patients who are reluctant to exercise to move along a continuum of activity between “no acticity” on one end and “recommended daily amounts” on the other.

This is even more important as many persons with HIV infection age and experience age-related cognitive impairments. Both computer-based cognitive training and transcranial direct current stimulation (tDCS have shown promise as interventions to improve cognitive function. In this study, we investigate the acceptability and efficacy of cognitive training with and without tDCS in older persons with HIV. Patients and methods: In this single-blind randomized study, participants were 14 individuals of whom 11 completed study procedures (mean age =51.5 years; nine men and two women with HIV-related mild neurocognitive disorder. Participants completed a battery of neuropsychological and self-report measures and then six 20-minute cognitive training sessions while receiving either active or sham anodal tDCS over the left dorsolateral prefrontal cortex. After training, participants completed the same measures. Success of the blind and participant reactions were assessed during a final interview. Assessments were completed by an assessor blind to treatment assignment. Pre- and post-training changes were evaluated via analysis of covariance yielding estimates of effect size. Results: All participants believed that they had been assigned to active treatment; nine of the 11 believed that the intervention had improved their cognitive functioning. Both participants who felt the intervention was ineffective were assigned to the sham condition. None of the planned tested interactions of time with treatment was significant, but 12 of 13 favored tDCS (P=0.08. All participants indicated that they would participate in similar studies in the future. Conclusion: Results show that both cognitive training via

    Full Text Available The train-bridge dynamic interaction problem began with the development of railway technology, and requires an evaluation method for bridge design in order to ensure the safety and stability of the bridge and the running train. This problem is studied using theoretical analysis, numerical simulation, and experimental study. In the train-bridge dynamic interaction system proposed in this paper, the train vehicle model is established by the rigid-body dynamics method, the bridge model is established by the finite element method, and the wheel/rail vertical and lateral interaction are simulated by the corresponding assumption and the Kalker linear creep theory, respectively. Track irregularity, structure deformation, wind load, collision load, structural damage, foundation scouring, and earthquake action are regarded as the excitation for the system. The train-bridge dynamic interaction system is solved by inter-history iteration. A case study of the dynamic response of a CRH380BL high-speed train running through a standard-design bridge in China is discussed. The dynamic responses of the vehicle and of the bridge subsystems are obtained for speeds ranging from 200 km·h−1 to 400 km·h−1, and the vibration mechanism are analyzed.

    The purpose of presented poster is to introduce the PONS2train developed for runoff prediction via multilayer perceptron - MLP. The software application enables the implementation of 12 different MLP's transfer functions, comparison of 9 local training algorithms and finally the evaluation the MLP performance via 17 selected model evaluation metrics. The PONS2train software is written in C++ programing language. Its implementation consists of 4 classes. The NEURAL_NET and NEURON classes implement the MLP, the CRITERIA class estimates model evaluation metrics and for model performance evaluation via testing and validation datasets. The DATA_PATTERN class prepares the validation, testing and calibration datasets. The software application uses the LAPACK, BLAS and ARMADILLO C++ linear algebra libraries. The PONS2train implements the first order local optimization algorithms: standard on-line and batch back-propagation with learning rate combined with momentum and its variants with the regularization term, Rprop and standard batch back-propagation with variable momentum and learning rate. The second order local training algorithms represents: the Levenberg-Marquardt algorithm with and without regularization and four variants of scaled conjugate gradients. The other important PONS2train features are: the multi-run, the weight saturation control, early stopping of trainings, and the MLP weights analysis. The weights initialization is done via two different methods: random sampling from uniform distribution on open interval or Nguyen Widrow method. The data patterns can be transformed via linear and nonlinear transformation. The runoff forecast case study focuses on PONS2train implementation and shows the different aspects of the MLP training, the MLP architecture estimation, the neural network weights analysis and model uncertainty estimation.

    Jorge Munoz-Paniagua

    2015-01-01

    Full Text Available The adjoint method is used in this paper for the aerodynamic optimization of the nose shape of a train. This method has been extensively applied in aircraft or ground vehicle aerodynamic optimization, but is still in progress in train aerodynamics. Here we consider this innovative optimization method and present its application to reduce the aerodynamic drag when the train is subjected to front wind. The objective of this paper is to demonstrate the effectiveness of the method, highlighting the requirements, limitations and capabilities of it. Furthermore, a significant reduction of the aerodynamic drag in a short number of solver calls is aimed as well. The independence of the computational cost with respect to the number of design variables that define the optimal candidate is stressed as the most interesting characteristic of the adjoint method. This behavior permits a more complete modification of the shape of the train nose because the number of design variables is not a constraint anymore. The information obtained from the sensitivity field permits determining the regions of the geometry where a small modification of the nose shape might introduce a larger improvement of the train performance. A good agreement between this information and the successive geometry modifications is observed here.

    In high voltage distribution systems, there are many power quality troubles due to voltage dips. Otherwise, a magnetizing inrush current causes the voltage dip. To suppress voltage dips, it is necessary to identify the magnetizing inrush current phenomena. In this paper, the authors propose a new identification method. The principles are that the saturation start/end flux is equal and the inrush current pattern exists. And to avoid a interfere with saturation area overlap; the rectangular coordinate method is adopted.

  3. Improvement of Power Flow Calculation with Optimization Factor Based on Current Injection Method

    Directory of Open Access Journals (Sweden)

    Lei Wang

    2014-01-01

    Full Text Available This paper presents an improvement in power flow calculation based on current injection method by introducing optimization factor. In the method proposed by this paper, the PQ buses are represented by current mismatches while the PV buses are represented by power mismatches. It is different from the representations in conventional current injection power flow equations. By using the combined power and current injection mismatches method, the number of the equations required can be decreased to only one for each PV bus. The optimization factor is used to improve the iteration process and to ensure the effectiveness of the improved method proposed when the system is ill-conditioned. To verify the effectiveness of the method, the IEEE test systems are tested by conventional current injection method and the improved method proposed separately. Then the results are compared. The comparisons show that the optimization factor improves the convergence character effectively, especially that when the system is at high loading level and R/X ratio, the iteration number is one or two times less than the conventional current injection method. When the overloading condition of the system is serious, the iteration number in this paper appears 4 times less than the conventional current injection method.

    The introduction of team-working often has positive effects on team members but places significant new demands on managers. Unfortunately, little research has examined whether the impact of the intervention may be enhanced by providing managers with training during the change process. To test...... this possibility we carried out a longitudinal intervention study (with a ‘no training’ comparison group) in a part of the Danish elderly care sector that was implementing teamwork. Kirkpatrick’s (1998) training evaluation model was used to examine the effects of training team managers in issues such as teamwork......, transformational leadership and change management on the outcomes of team implementation. We used a combination of quantitative and qualitative research methods to isolate the impact of manager training on the success of the teamwork intervention.

  5. Batch gradient method with smoothing L1/2 regularization for training of feedforward neural networks.

    Wu, Wei; Fan, Qinwei; Zurada, Jacek M; Wang, Jian; Yang, Dakun; Liu, Yan

    2014-02-01

    The aim of this paper is to develop a novel method to prune feedforward neural networks by introducing an L1/2 regularization term into the error function. This procedure forces weights to become smaller during the training and can eventually removed after the training. The usual L1/2 regularization term involves absolute values and is not differentiable at the origin, which typically causes oscillation of the gradient of the error function during the training. A key point of this paper is to modify the usual L1/2 regularization term by smoothing it at the origin. This approach offers the following three advantages: First, it removes the oscillation of the gradient value. Secondly, it gives better pruning, namely the final weights to be removed are smaller than those produced through the usual L1/2 regularization. Thirdly, it makes it possible to prove the convergence of the training. Supporting numerical examples are also provided.

    In this review, we give a brief outline of robot-mediated gait training for stroke patients, as an important emerging field in rehabilitation. Technological innovations are allowing rehabilitation to move toward more integrated processes, with improved efficiency and less long-term impairments. In particular, robot-mediated neurorehabilitation is a rapidly advancing field, which uses robotic systems to define new methods for treating neurological injuries, especially stroke. The use of robots in gait training can enhance rehabilitation, but it needs to be used according to well-defined neuroscientific principles. The field of robot-mediated neurorehabilitation brings challenges to both bioengineering and clinical practice. This article reviews the state of the art (including commercially available systems) and perspectives of robotics in poststroke rehabilitation for walking recovery. A critical revision, including the problems at stake regarding robotic clinical use, is also presented. PMID:28553117

Dickman is a type locality for the geology that will be encountered for CO{sub 2} sequestration projects from northern Oklahoma across the U.S. midcontinent to Indiana and Illinois. Since its discovery in 1962, the Dickman Field has produced about 1.7 million barrels of oil from porous Mississippian carbonates with a small structural closure at about 4400 ft drilling depth. Project data includes 3.3 square miles of 3D seismic data, 142 wells, with log, some core, and oil/water production data available. Only two wells penetrate the deep saline aquifer. In a previous DOE-funded project, geological and seismic data were integrated to create a geological property model and a flow simulation grid. We believe that sequestration of CO{sub 2} will largely occur in areas of relatively flat geology and simple near surface, similar to Dickman. The challenge is not complex geology, but development of improved, lower-cost methods for detecting natural fractures and subtle faults. Our project used numerical simulation to test methods of gathering multicomponent, full azimuth data ideal for this purpose. Our specific objectives were to apply advanced seismic methods to aide in quantifying reservoir properties and lateral continuity of CO{sub 2} sequestration targets. The purpose of the current project is graduate and undergraduate student training related to improved 3D seismic technology that addresses key challenges related to monitoring movement and containment of CO{sub 2

    Full Text Available Nowadays, active power filter plays an important role in reducing harmonic current and reactive power in power lines. The reliability and effectiveness of an active power filter depends basically on three characteristics. These are the modulation method, the design characteristics of the PWM modulator and the method implemented to generate compensation current. For the last one, there are many proposed methods. Most of them complicated and hence difficult to implement and adjust. In this study, a new method to calculate compensation current is improved and tested in single-phase parallel active power filter controlled by microcontroller. Experimental and simulation results are presented in the paper.

    Maeda, Tatsuhiko; Naitoh, Tadashi; Toyama, Atsushi; Takeda, Keiki

    In this paper, the authors propose an improved identification method of the magnetizing inrush current phenomena. A first improvement is the development of determinant method about the transformer connection, which gives a calculation method of magnetic flux, using with theoretical pattern of inrush current ratio. And then, since the Aitken's Δ2-process, which uses the estimation of the saturation on/off time, has many extrema, it is difficult to determinate the saturation on/off time. Therefore, using the pattern of derivative current, a new determinant method of the saturation on/off time is developed.

    This study aimed to evaluate the impact of an educational intervention in lower genital tract pathology (LGTP) on the knowledge and skills acquired by the Spanish specialist residents. This didactic change was carried out under the auspices of the Asociación Española de Patología Cervical y Colposcopia and the Sociedad Española Ginecología y Obstetricia and its Resident Section. This is an observational, descriptive, and cross-sectional study. The survey was composed of 15 questions voluntarily answered by Spanish gynecology and obstetrics trainees. Compared with a previous survey, a substantial increase in the proportion of Spanish teaching hospitals with an LGTP unit (9/42 vs 47/59) has been detected while doubling the percentage of residents who acknowledge medium to high knowledge on this pathology. The same cannot be said about the handling capacity of vulvodynia registering a great improvement. Spanish scientific societies, concerned in the quality of LGTP training gained by their residents, have focused on the necessity of LGTP units. Our study confirms the usefulness of this performance in the new continued LGTP education.

    @@ The driving laser field assisted attosecond soft-extreme-ultraviolet (XUV) photo-ionization was used successfully to measure the duration of the attosecond pulse based on the cross-correlation method. However, this method in principle cannot distinguish a single attosecond pulse from the attosecond pulse train. We propose a technique for directly distinguishing attosecond single pulse from attosecond pulse train based on the photo-ionization of atoms by attosecond XUV pulse in the presence of a two-colour strong laser pulse.

    The present study examined the efficacy of online training (OLT), instructor-led training (ILT), and a treatment manual (TM) in training mental health clinicians in two core strategies of Dialectical Behavior Therapy (DBT): chain analysis and validation. A randomized controlled trial compared OLT, ILT, and TM among clinicians naïve to DBT (N=172) who were assessed at baseline, post-training, and 30, 60, and 90 days following training. Primary outcomes included satisfaction, self-efficacy, motivation, knowledge, clinical proficiency, and clinical use. Overall, ILT outperformed OLT and TM in satisfaction, self-efficacy, and motivation, whereas OLT was the most effective method for increasing knowledge. The conditions did not differ in observer-rated clinical proficiency or self-reported clinical use, which both increased to moderate levels after training. In addition, ILT was particularly effective at improving motivation to use chain analysis, whereas OLT was particularly effective at increasing knowledge of validation strategies. These findings suggest that these types of brief, didactic trainings may be effective methods of increasing knowledge of new treatment strategies, but may not be sufficient to enable clinicians to achieve a high level of clinical use or proficiency. Additional research examining the possible advantages of matching training methods to types of treatment strategies may help to determine a tailored, more effective approach to training clinicians in empirically supported treatments.

    Generation of current references constitutes an important part in the control of active power filters (APFs) used in power system, since any inaccuracy in reference currents yields to incorrect compensation. In this paper, harmonic detection methods for generating reference currents have been evaluated on the basis of three-phase balanced and unbalanced load currents processed in the digital signal processor (DSP). The advantages and disadvantages of several methods found in the literature have been discussed on the basis of simulation results. Three of these methods have been programmed in the TMS320F2812 digital signal processor (DSP) unit and their performances are evaluated from the viewpoint of practical considerations. Finally, instantaneous reactive power method to estimate the APF reference currents is implemented and its practical results obtained under balanced and unbalanced loads are given. (author)

    Orphan proteins are characterized by the lack of significant sequence similarity to database proteins. To infer the functional properties of the orphans, more elaborate techniques that utilize structural information are required. In this regard, the protein structure prediction gains considerable importance. Secondary structure prediction algorithms designed for orphan proteins (also known as single-sequence algorithms) cannot utilize multiple alignments or alignment profiles, which are derived from similar proteins. This is a limiting factor for the prediction accuracy. One way to improve the performance of a single-sequence algorithm is to perform re-training. In this approach, first, the models used by the algorithm are trained by a representative set of proteins and a secondary structure prediction is computed. Then, using a distance measure, the original training set is refined by removing proteins that are dissimilar to the given protein. This step is followed by the re-estimation of the model parameters and the prediction of the secondary structure. In this paper, we compare training set reduction methods that are used to re-train the hidden semi-Markov models employed by the IPSSP algorithm [1]. We found that the composition based reduction method has the highest performance compared to the alignment based and the Chou-Fasman based reduction methods. In addition, threshold-based reduction performed better than the reduction technique that selects the first 80% of the dataset proteins.

    This paper presents the rationale and methods for a randomized controlled evaluation of web-based training in motivational interviewing, goal setting, and behavioral task assignment. Web-based training may be a practical and cost-effective way to address the need for large-scale mental health training in evidence-based practice; however, there is a dearth of well-controlled outcome studies of these approaches. For the current trial, 168 mental health providers treating post-traumatic stress disorder (PTSD) were assigned to web-based training plus supervision, web-based training, or training-as-usual (control). A novel standardized patient (SP) assessment was developed and implemented for objective measurement of changes in clinical skills, while on-line self-report measures were used for assessing changes in knowledge, perceived self-efficacy, and practice related to cognitive behavioral therapy (CBT) techniques. Eligible participants were all actively involved in mental health treatment of veterans with PTSD. Study methodology illustrates ways of developing training content, recruiting participants, and assessing knowledge, perceived self-efficacy, and competency-based outcomes, and demonstrates the feasibility of conducting prospective studies of training efficacy or effectiveness in large healthcare systems.

    Full Text Available Introduction: Considering the increasing trend of obesity and the effects of limited physical activity on raising the incidence of childhood obesity, and on noting the limitations of families for sending their children to sport and exercise classes, and the limited time of students for participation in such classes, finding appropriate ways for training physical activity at home is necessary. Methods: This non pharmacological trial was conducted during 6 months among 105 obese children and adolescents who were randomly assigned in 3 groups with 35 participants. Dietary counseling and behavioral management was similar for all groups, but in one group physical activity was conducted by attending sport classes twice a week; the second group members were trained for physical activity through an educational CD and the third group were trained by face to face education. Anthropometric indexes were measured before and after intervention. Results: After the trial, the mean body mass index (BMI decreased significantly in the group attending sport classes and the group trained by CD. However, no significant difference was observed between the three groups who received different forms of training. Conclusion: The finding of our study showed that training through CD can be as effective as face to face education and attending sport classes. Dissemination of such type of interventions can be effective at community level.

    Transcranial direct current stimulation (tDCS) is a neuromodulatory technique that has been extensively studied. While there have been initial positive results in some clinical trials, there is still variability in tDCS results. The aim of this article is to review and discuss patents assessing novel methods to optimize the use of tDCS. A systematic review was performed using Google patents database with tDCS as the main technique, with patents filling date between 2010 and 2015. Twenty-two patents met our inclusion criteria. These patents attempt to address current tDCS limitations. Only a few of them have been investigated in clinical trials (i.e., high-definition tDCS), and indeed most of them have not been tested before in human trials. Further clinical testing is required to assess which patents are more likely to optimize the effects of tDCS. We discuss the potential optimization of tDCS based on these patents and the current experience with standard tDCS.

    2003-01-01

    Since the volume transport across the pycnocline is much smaller than that in the mixed layer, the current in the mixed layer can be regarded as non-divergent. An objective analysis method is deduced based on this hypothesis. The linear combination method is used to solve the non-divergent component of the current field of an ocean basin containing islands,which is equivalent to a mathematical problem of solving a Poisson equation in a multi-connected domain. The method is applied to the Bohai Sea, the Yellow Sea and the East China Sea (ECS). The modeled result is consistent with the current maps constructed by other oceanographers.

    Full Text Available It is shown that computer systems for measuring current-voltage characteristics are very important for semiconductor devices production. The main criteria of efficiency of such systems are defined. It is shown that efficiency of such systems significantly depends on the methods for measuring current-voltage characteristics of semiconductor devices. The aim of this work is to analyze existing methods for measuring current-voltage characteristics of semiconductor devices and to create the classification of these methods in order to specify the most effective solutions in terms of defined criteria. To achieve this aim, the most common classifications of methods for measuring current-voltage characteristics of semiconductor devices and their main disadvantages are considered. Automated and manual, continuous, pulse, mixed, isothermal and isodynamic methods for measuring current-voltage characteristics are analyzed. As a result of the analysis and generalization of existing methods the next classification criteria are defined: the level of automation, the form of measurement signals, the condition of semiconductor device during the measurements, and the use of mathematical processing of the measurement results. With the use of these criteria the classification scheme of methods for measuring current-voltage characteristics of semiconductor devices is composed and the most effective methods are specified.

    The purpose of the current study was to assess the effect of opioid overdose prevention training on participants' knowledge about opioid overdose and confidence to recognize and respond to opioid overdose situations as a function of naloxone administration (i.e., injection vs. intranasal spray) and participant type (friend/family, provider, "other"). Opioid overdose prevention trainings were offered throughout a mid-sized metropolitan area in the northeast. Participants (n = 428) were trained to administer naloxone via intramuscular injection (n = 154) or intranasal spray (n = 274). All training participants were given pre-post assessments of knowledge about opioid overdose and confidence to recognize and respond to opioid overdose situations. Participants' overall knowledge and confidence increased significantly from pre- to post-training (ps type. Knowledge significantly increased from pre- to post-training in all participant types (ps Confidence improved significantly from pre- to post-training across both routes of administration (ps confidence was higher among those who were trained using the intranasal naloxone compared to those who were trained using the intramuscular injection naloxone at pre- (p = .011) and post-training (p Confidence increased from pre- to post-training in each of the participant types (ps confidence was higher among providers and friends/family members compared to "other" participants, such as first responders, only at post-training (p confidence related to opioid overdose situations. Findings suggest that trainees are more confident administering naloxone via intranasal spray compared to injection. Future research should attempt to identify other factors that may increase the likelihood of trainees' effectively intervening in opioid overdose situations.

    Full Text Available Abstract Background The use of electronic training devices for dog training is controversial. The aims of this study were to give an indication of the extent to which dog owners use these devices in England, identify factors associated with their use, and compare owner report of outcomes. A convenience sample of dog owners in England was used to identify numbers using electronic training devices and identify reasons for use. Factors associated with use of remote e-collars only were determined by comparing dogs trained using these devices with two control populations matched for reason of use (recall / chasing problems. Comparison groups were: those using other ‘negative reinforcement / positive punishment’ training techniques, and those using ‘positive reinforcement / negative punishment’ based methods. A multinominal logistic regression model was used to compare factors between categories of training method. Owner reported success for use was compared using chi-squared analysis. Results For England only, 3.3% (n = 133 owners reported using remote activated e-collars, 1.4% (n = 54 reported use of bark activated e-collars, and 0.9% (n = 36 reported using electronic boundary fences. In comparison with the e-collar group, owners using reward based training methods for recall / chasing were 2.8 times more likely to be female and 2.7 times less likely to have attended agility training. Owners using other aversive methods for recall / chasing were 2.8 times more likely to have attended puppy classes than those using e-collars. However, the model only explained 10% variance between groups. A significantly higher proportion of owners in the reward group reported training success than those in the e-collar group. Conclusions In conclusion, a fairly low proportion of owners select to use electronic training devices. For a population matched by reason for training method use, characteristics of dogs, including occurrence of undesired

    Eddy current thermography is a new NDT-technique for the detection of cracks in electro conductive materials. It combines the well-established inspection techniques of eddy current testing and thermography. The technique uses induced eddy currents to heat the sample being tested and defect detection is based on the changes of induced eddy currents flows revealed by thermal visualization captured by an infrared camera. The advantage of this method is to use the high performance of eddy current testing that eliminates the known problem of the edge effect. Especially for components of complex geometry this is an important factor which may overcome the increased expense for inspection set-up. The paper presents the possibility of applying eddy current thermography method for detecting defects in ballistic covers made of carbon fiber reinforced composites used in the construction of military vehicles.

  17. Modified Bean Model and FEM Method Combined for Persistent Current Calculation in Superconducting Coils

    Völlinger, Christine; Russenschuck, Stephan

    2001-01-01

    Field variations in the LHC superconducting magnets, e. g. during the ramping of the magnets, induce magnetization currents in the superconducting material, the so-called persistent currents that do not decay but persist due to the lack of resistivity. This paper describes a semi-analytical hysteresis model for hard superconductors, which has been developed for the computation of the total field errors arising from persistent currents. Since the superconducting coil is surrounded by a ferromagnetic yoke structure, the persistent current model is combined with the finite element method (FEM), as the non-linear yoke can only be calculated numerically. The used finite element method is based on a reduced vector potential formulation that avoids the meshing of the coil while calculating the part of the field arising from the source currents by means of the Biot-Savart Law. The combination allows to determine persistent current induced field errors as function of the excitation and for arbitrarily shaped iron yoke...

    Metal oxide surge arresters are one of the most important equipment for power system protection against switching and lightning over-voltages. High-energy stresses and environmental features are the main factors which degrade surge arresters. In order to verify surge arresters good condition, their monitoring is necessary. The majority of surge arrester monitoring techniques is based on total leakage current decomposition of their capacitive and resistive components. This paper introduces a new approach based on time-delay addition method to extract the resistive current from the total leakage current without measuring voltage signal. Surge arrester model for calculating leakage current has been performed in ATP-EMTP. In addition, the signal processing has been done using MATLAB software. To show the accuracy of the proposed method, experimental tests have been performed to extract resistive leakage current by the proposed method.

    The US Army pioneered medical evacuation (MEDEVAC) by helicopter, yet its system remains essentially unchanged since the Vietnam era. Care is provided by a single combat medic credentialed at the Emergency Medical Technician - Basic level. Treatment protocols, documentation, medical direction, and quality improvement processes are not standardized and vary significantly across US Army helicopter evacuation units. This is in contrast to helicopter emergency medical services that operate within the United States. Current civilian helicopter evacuation platforms are routinely staffed by critical care-trained flight paramedics (CCFP) or comparably trained flight nurses who operate under trained EMS physician medical direction using formalized protocols, standardized patient care documentation, and rigorous quality improvement processes. This study compares mortality of patients with injury from trauma between the US Army's standard helicopter evacuation system staffed with medics at the Emergency Medical Technician - Basic level (standard MEDEVAC) and one staffed with experienced CCFP using adopted civilian helicopter emergency medical services practices. This is a retrospective study of a natural experiment. Using data from the Joint Theater Trauma Registry, 48-hour mortality for severely injured patients (injury severity score ≥ 16) was compared between patients transported by standard MEDEVAC units and CCFP air ambulance units. The 48-hour mortality for the CCFP-treated patients was 8% compared to 15% for the standard MEDEVAC patients. After adjustment for covariates, the CCFP system was associated with a 66% lower estimated risk of 48-hour mortality compared to the standard MEDEVAC system. These findings demonstrate that using an air ambulance system based on modern civilian helicopter EMS practice was associated with a lower estimated risk of 48-hour mortality among severely injured patients in a combat setting.

    Accurate identification of bursting activity is an essential element in the characterization of neuronal network activity. Despite this, no one technique for identifying bursts in spike trains has been widely adopted. Instead, many methods have been developed for the analysis of bursting activity, often on an ad hoc basis. Here we provide an unbiased assessment of the effectiveness of eight of these methods at detecting bursts in a range of spike trains. We suggest a list of features that an ideal burst detection technique should possess and use synthetic data to assess each method in regard to these properties. We further employ each of the methods to reanalyze microelectrode array (MEA) recordings from mouse retinal ganglion cells and examine their coherence with bursts detected by a human observer. We show that several common burst detection techniques perform poorly at analyzing spike trains with a variety of properties. We identify four promising burst detection techniques, which are then applied to MEA recordings of networks of human induced pluripotent stem cell-derived neurons and used to describe the ontogeny of bursting activity in these networks over several months of development. We conclude that no current method can provide "perfect" burst detection results across a range of spike trains; however, two burst detection techniques, the MaxInterval and logISI methods, outperform compared with others. We provide recommendations for the robust analysis of bursting activity in experimental recordings using current techniques.

    To evaluate the effectiveness of two training methods for avoiding excessive inflation of laryngeal mask airway(LMA)Supreme. Totally 41 anesthesiologists were randomly divided into hand touch group(H group,n=20)and short-term pressure gauge training group(G group,n=21). Before training,subjects were asked to inflate the cuff of LMA Supreme to two target pressures,30 cmH(2)O and 60 cmH(2)O, according to their own experiences. The actual cuff pressures were recorded as baseline pressures. Subjects in H group then received the training of hand touch:touch the vermilion of the lip and apex nasi with the left ring finger and feel the hardness. A cuff pressure with hardness similar to the vermilion of the lip was defined as 30 cmH(2)O, and similar to the apex nasi as 60 cmH(2)O. Subjects in G group were asked to inflate the cuff with a pressure gauge and feel the hardness of the cuff when the pressure reached 30 cmH(2)O and 60 cmH(2)O. After one-week training,two groups of subjects repeated the cuff inflation test. Actual cuff pressures after training were also recorded and compared with the baseline pressures. Results Actual cuff pressures after training[Group H:(39.7±15.7) cmH(2)O(P=0.00);Group G:(26.2±13.2) cmH(2)O(P=0.03)]were significantly lower than baseline pressures in both groups when the target cuff pressure was 30 cmH(2)O, and the differences were not statistically significant between these two groups(P=0.06). When the target pressure was 60 cmH(2)O,the actual cuff pressure of H group [(91.1±24.3)cmH(2)O] was significantly higher than that of G group [(58.1±15.4) cmH(2)O (P=0.01)]. However,the actual cuff pressure of G group was similar to the target pressure. The two training methods are equally effective when the target pressure is 30 cmH(2)O, while short-term pressure gauge training method is superior when the target pressure is 60 cmH(2)O.

    In the present study we tested the cognitive effects of transcranial direct current stimulation (tDCS) in a case of probable Alzheimer disease (AD). The patient (male, 60 years, mild AD) underwent two cycles of treatments, separated by 2 months. In the first cycle, active stimulation (10 sessions, 2 mA for 20 min; anode over the left dorsolateral prefrontal cortex) was followed by computerised tasks (CTs) specifically chosen to engage the most impaired cognitive processes in the patient (tDCS+CT condition). In the second cycle, which was structured as the first, CTs were administered after placebo stimulation (sham+CT condition). Effects on cognitive performance were evaluated not only by the CTs, but also by neuropsychological tests assessing global cognitive functioning. Statistical analyses revealed that whereas the tDCS+CT condition had few effects on the CTs, it induced a stability of the patient's global cognitive functioning lasting approximately 3 months, which was not achieved when the patient underwent sham+CT condition. Therefore, the synergetic use of tDCS and CTs appeared to slow down the cognitive decline of our patient. This preliminary result, although in need of further confirmation, suggests the potentiality of tDCS as an adjuvant tool for cognitive rehabilitation in AD.

    This paper presents the current control method of thyristor converter which is applied to PF power supply in KSTAR. The thyristor converter for PF superconducting coil is composed of two 6 pulse converters and each converter is connected in parallel using DC reactor to reduce voltage ripple, current rating of converter and harmonic components. For 4 quadrant operation, each 6 pulse converter has six arms of anti-paralleled thyristor device, back-to-back connection. To apply this converter on KSTAR PF coil, stable coil current control is needed. Additionally, PF coil needs smooth current control without dead-time when current polarity changes and it is not easy in back-to-back thyristor converter. For this reason, zero crossing current control using circulating current and test results are introduced in this paper and it was satisfactory.

  15. A new method of reconstructing current paths in HTS tapes with defects

    Science.gov (United States)

    Podlivaev, Alexey; Rudnev, Igor

    2017-03-01

    We propose a new method for calculating current paths in high-temperature superconductive (HTS) tapes with various defects including cracks, non-superconducting inclusions, and superconducting inclusions with lower local critical current density. The calculation method is based on a model of critical state which takes into account the dependence of the critical current on the magnetic field. The method allows us to calculate the spatial distribution of currents flowing through the defective HTS tape for both currents induced by the external magnetic field and transport currents from an external source. For both cases, we performed simulations of the current distributions in these tapes with different types of defects and have shown that the combination of the action of the magnetic field and transport current leads to a more detailed identification of the boundaries and shape of the defects. The proposed method is adapted for calculating modern superconductors in real superconducting devices and may be more useful as compared to the conventional magnetometric diagnostic studies, when the tape is affected by the magnetic field only.

    In order to meet the high ampacity requirement of a low voltage main feeder, single-core power cables are usually connected in parallel in Taiwan's industrial and commercial power distribution systems. However, parallel connected cables can be problematic due to unequal current distributions among cables of the same phase, causing excessive temperature rise in the heavier loading cables, thus reducing the life expectancy of cable insulation. One of the most effective and economical methods of balancing current distributions is a properly designed cable position arrangement. This paper proposed a cable position sorting method for the balance of current distribution of parallel connected cables. A current distribution calculation method was developed based on mutual inductance theorem and the numerical iteration technique. In order to implement the sorting algorithm, two current distribution indices were proposed for the power loss of all cables and for the largest cable current value. The index values of different cable arrangement patterns generated by a novel permutation reduction method were determined and sorted and 3 cable configurations were studied. Recommendations for the arrangement of cable positions, aiming for more balanced current distributions, were also presented. It was concluded that dividing the cables into subgroups, including only one cable per phase in a subgroup, and arranging the cables in symmetric form can achieve a very balanced current distribution. 5 refs., 14 tabs., 7 figs.

    The adaptations of the human body resulting from the aging process especially loss of flexibility can increase the risk of falls and the risk of developing other health conditions. Exercise training, in particular the Pilates exercise method, has become an important form of physical activity that minimizes the deleterious effects of aging on flexibility. Few studies have evaluated the effect of this training method on body flexibility among elderly. We aimed to evaluate the effects of physical training using the Pilates method on body flexibility of elderly individuals. Eighteen elderly women and two elderly men (aged 70 ± 4 years) followed a 10-week Pilates training program. Individuals were recruited from the local community via open invitations. At study entry, none of them had limited mobility (walking requiring the use of walkers or canes). Furthermore, those with neurologic, muscular, or psychiatric disorders as well as those using an assistive device for ambulation were excluded secondary to limited participation. Flexibility assessment tests (flexion, extension, right and left tilt, and right and left rotation of the cervical and thoracolumbar spine; flexion, extension, abduction, and lateral and medial right and left rotation of the glenohumeral joint; flexion, extension, abduction, adduction, and lateral and medial rotation of the right and left hip; and flexion of the right and left knee) were performed by a blinded evaluator using a flexometer before and after the training period. All assessments were carried out at the same time of day. There was an observed increase in flexion (22.86%; p training may minimize the deleterious effects of aging and may improve the functionality of elderly individuals, which would reduce the likelihood of accidents (especially falls).

    2015-08-01

    In the context of quantitative electromyography (EMG), it is of major interest to obtain a waveform that faithfully represents the set of potentials that constitute a motor unit action potential (MUAP) train. From this waveform, various parameters can be determined in order to characterize the MUAP for diagnostic analysis. The aim of this work was to conduct a thorough, in-depth review, evaluation and comparison of state-of-the-art methods for composing waveforms representative of MUAP trains. We evaluated nine averaging methods: Ensemble (EA), Median (MA), Weighted (WA), Five-closest (FCA), MultiMUP (MMA), Split-sweep median (SSMA), Sorted (SA), Trimmed (TA) and Robust (RA) in terms of three general-purpose signal processing figures of merit (SPMF) and seven clinically-used MUAP waveform parameters (MWP). The convergence rate of the methods was assessed as the number of potentials per MUAP train (NPM) required to reach a level of performance that was not significantly improved by increasing this number. Test material comprised 78 MUAP trains obtained from the tibialis anterioris of seven healthy subjects. Error measurements related to all SPMF and MWP parameters except MUAP amplitude descended asymptotically with increasing NPM for all methods. MUAP amplitude showed a consistent bias (around 4% for EA and SA and 1-2% for the rest). MA, TA and SSMA had the lowest SPMF and MWP error figures. Therefore, these methods most accurately preserve and represent MUAP physiological information of utility in clinical medical practice. The other methods, particularly WA, performed noticeably worse. Convergence rate was similar for all methods, with NPM values averaged among the nine methods, which ranged from 10 to 40, depending on the waveform parameter evaluated.

    The scope of general surgery practice has evolved tremendously in the last 20 years. However, clinical experience in general surgery residency training has undergone relatively little change. To evaluate the current scope of academic general surgery and its implications on surgical residency. The University HealthSystem Consortium and Association of American Medical Colleges established the Faculty Practice Solution Center (FPSC) to characterize physician productivity. The FPSC is a benchmarking tool for academic medical centers created from revenue data collected from more than 90,000 physicians who practice at 95 institutions across the United States. The FPSC database was queried to evaluate the annual mean procedure frequency per surgeon (PFS) in each calendar year from 2006 through 2011. The associated work relative value units (wRVUs) were also examined to measure physician effort and skill. During the 6-year period, 146 distinct Current Procedural Terminology codes were among the top 100 procedures, and 16 of these procedures ranked in the top 10 procedures in at least 1 year. The top 10 procedures accounted for more than half (range, 52.5%-57.2%) of the total 100 PFS evaluated for each year. Laparoscopic Roux-en-Y gastric bypass was consistently among the top 10 procedures in each year (PFS, 18.2-24.6). The other most frequently performed procedures included laparoscopic cholecystectomy (PFS, 30.3-43.5), upper gastrointestinal tract endoscopy (PFS, 26.5-34.3), mastectomy (PFS, 16.5-35.0), inguinal hernia repair (PFS, 15.5-22.1), and abdominal wall hernia repair (PFS, 21.6-26.1). In all years, laparoscopic Roux-en-Y gastric bypass generated the highest number of wRVUs (wRVUs, 491.0-618.2), and laparoscopic cholecystectomy was regularly the next highest (wRVUs, 335.8-498.7). A significant proportion of academic general surgery is composed of bariatric surgery, yet surgical training does not sufficiently emphasize the necessary exposure to technical expertise

For reliable design, the operating temperature of the dc-link capacitor should be known, which is primarily determined by the ambient temperature and the rms value...... of the current flowing through the dc-link capacitor. A simple analytical method to calculate the rms value of the dc-link capacitor current is presented in this paper. The effect of the line current ripple on the rms value of the dc-link capacitor current is considered. This yields accurate results, especially...

    According to the limitations of the LVRT technology of traditional photovoltaic inverter existed, this paper proposes a low voltage ride through (LVRT) control method based on model current predictive control (MCPC). This method can effectively improve the photovoltaic inverter output characteristics and response speed. The MCPC method of photovoltaic grid-connected inverter designed, the sum of the absolute value of the predictive current and the given current error is adopted as the cost function with the model predictive control method. According to the MCPC, the optimal space voltage vector is selected. Photovoltaic inverter has achieved automatically switches of priority active or reactive power control of two control modes according to the different operating states, which effectively improve the inverter capability of LVRT. The simulation and experimental results proves that the proposed method is correct and effective.

    According to the characteristics of single-phase circuits and demand of using active filter for real-time detecting harmonic and reactive currents, a detecting method based on Fryze's power definition is proposed. The results of theoretical analysis and simulation show that the proposed method is effective in real-time detecting of instantaneous harmonic and reactive currents in single-phase circuits. When only detecting the total reactive currents, this method does not need a phase-locked loop circuit, and it also can be used in some special applications to provide different compensations on the ground of different requirements of electric network. Compared with the other methods based on the theory of instantaneous reactive power, this method is simple and easy to realize.

    Recently developed lower-limb prostheses are capable of actuating the knee and ankle joints, allowing amputees to perform advanced locomotion modes such as step-over-step stair ascent and walking on sloped surfaces. However, transitions between these locomotion modes and walking are neither automatic nor seamless. This study describes methods for construction and training of a high-level intent recognition system for a lower-limb prosthesis that provides natural transitions between walking, stair ascent, stair descent, ramp ascent, and ramp descent. Using mechanical sensors onboard a powered prosthesis, we collected steady-state and transition data from six transfemoral amputees while the five locomotion modes were performed. An intent recognition system built using only mechanical sensor data was 84.5% accurate using only steady-state training data. Including training data collected while amputees performed seamless transitions between locomotion modes improved the overall accuracy rate to 93.9%. Training using a single analysis window at heel contact and toe off provided higher recognition accuracy than training with multiple analysis windows. This study demonstrates the capability of an intent recognition system to provide automatic, natural, and seamless transitions between five locomotion modes for transfemoral amputees using powered lower limb prostheses.

    In the last decade, important advances in the field of cognitive science, psychology, and neuroscience have largely contributed to improve our knowledge on brain functioning. More recently, a line of research has been developed that aims at using musical training and practice as alternative tools for boosting specific perceptual, motor, cognitive, and emotional skills both in healthy population and in neurologic patients. These findings are of great hope for a better treatment of language-based learning disorders or motor impairment in chronic non-communicative diseases. In the first part of this review, we highlight several studies showing that learning to play a musical instrument can induce substantial neuroplastic changes in cortical and subcortical regions of motor, auditory and speech processing networks in healthy population. In a second part, we provide an overview of the evidence showing that musical training can be an alternative, low-cost and effective method for the treatment of language-based learning impaired populations. We then report results of the few studies showing that training with musical instruments can have positive effects on motor, emotional, and cognitive deficits observed in patients with non-communicable diseases such as stroke or Parkinson Disease. Despite inherent differences between musical training in educational and rehabilitation contexts, these results favor the idea that the structural, multimodal, and emotional properties of musical training can play an important role in developing new, creative and cost-effective intervention programs for education and rehabilitation in the next future.

    2011-01-01

    Based on the discrete time method, an effective movement control model is designed for a group of high- speed trains on a rail network. The purpose of the model is to investigate the specific traffic characteristics of high-speed trains under the interruption of stochastic irregular events. In the model, the high-speed rail traffic system is supposed to be equipped with the moving-block signalling system to guarantee maximum traversing capacity of the railway. To keep the safety of trains' movements, some operational strategies are proposed to control the movements of trains in the model, including traction operation, braking operation, and entering-station operation. The numerical simulations show that the designed model can well describe the movements of high-speed trains on the rail network. The research results can provide the useful information not only for investigating the propagation features of relevant delays under the irregular disturbance but also for rerouting and reseheduling trains on the rail network.

    1990-05-01

    This thesis describes the development of a design tool for the poloidal field magnet system of a tokamak. Specifically, an existing program for determining the poloidal field coil currents has been modified to: support the general case of asymmetric equilibria and coil sets, determine the coil currents subject to constraints on the maximum values of those currents, and determine the coil currents subject to limits on the forces those coils may carry. The equations representing the current limits and coil force limits are derived and an algorithm based on Newton's method is developed to determine a set of coil currents which satisfies those limits. The resulting program allows the designer to quickly determine whether or not a given coil set is capable of supporting a given equilibrium. 25 refs.

    This paper proposes a new training support method called self-coaching with humanoid robots. In the proposed method, two small size inexpensive humanoid robots are used because of their availability. One robot called target robot reproduces motion of a target player and another robot called reference robot reproduces motion of an expert player. The target player can recognize a target technique from the reference robot and his/her inadequate skill from the target robot. Modifying the motion of the target robot as self-coaching, the target player could get advanced cognition. Some experimental results show some possibility as the new training method and some issues of the self-coaching interface program as a future work.

    The acquisition and improvement of surgical skills constitute a fundamental element in the training of any practitioner. At present, however, the assessment of these skills is a scarcely developed area of research. The aim of this study was to analyse the peculiarities of the various assessment systems and establish the minimum criteria that a skills and knowledge assessment system should meet as a method for assessing surgical skills in urological surgery. Scientific literature review aimed at the various currently available assessment systems for skills and competencies (technical and nontechnical), with a special focus on the systematic reviews and prospective studies. After conducting the review, we found that the various assessment systems for surgical competence have, in our opinion, a number of shortcomings. There is a certain degree of subjectivity in the assessment of surgeons by the evaluators. The assessment of nontechnical competencies is not formally recorded. There is no description of a follow-up assessment or any basic parameters associated with healthcare quality. There is no registration of associated competencies associated with the various surgical techniques. There is also no ranking of these competencies and the specific peculiarities for their application. We believe that the development of a new assessment system for surgical competencies (technical and nontechnical) aimed at assessing urologists in the various surgical techniques is necessary. To this end, our team has worked on developing the Evaluation System for Surgical Competencies on Laparoscopy, which is based on the definition, ranking and assessment of competencies demonstrated by surgeons.

    The aerodynamic performances of a passenger car and a box car with different heights of windbreak walls under strong wind were studied using the numerical simulations, and the changes of aerodynamic side force, lift force and overturning moment with different wind speeds and wall heights were calculated. According to the principle of static moment balance of vehicles, the overturning coefficients of trains with different wind speeds and wall heights were obtained. Based on the influence of wind speed and wall height on the aerodynamic performance and the overturning stability of trains, a method of determination of the load balance ranges for the train operation safety was proposed, which made the overturning coefficient have nearly closed interval. A min(|A1|+|A2|), s.t.|A1|→|A2|(A1 refers to the downwind overturning coefficient and A2 refers to the upwind overturning coefficient) was found. This minimum value helps to lower the wall height as much as possible, and meanwhile, guarantees the operation safety of various types of trains under strong wind. This method has been used for the construction and improvement of the windbreak walls along the Lanzhou–Xinjiang railway (from Lanzhou to Urumqi, China).

    The detection of ventricular beats in the holter recording is a task of great importance since it can direct clinicians toward the parts of the electrocardiogram record that might be crucial for determining the final diagnosis. Although there already exists a fair amount of research work dealing with ventricular beat detection in holter recordings, the vast majority uses a local training approach, which is highly disputable from the point of view of any practical-real-life-application. In this paper, we compare five well-known methods: a classical decision tree approach and its variant with fuzzy rules, a self-organizing map clustering method with template matching for classification, a back-propagation neural network and a support vector machine classifier, all examined using the same global cross-database approach for training and testing. For this task two databases were used-the MIT-BIH database and the AHA database. Both databases are required for testing any newly developed algorithms for holter beat classification that is going to be deployed in the EU market. According to cross-database global training, when the classifier is trained with the beats from the records of one database then the records from the other database are used for testing. The results of all the methods are compared and evaluated using the measures of sensitivity and specificity. The support vector machine classifier is the best classifier from the five we tested, achieving an average sensitivity of 87.20% and an average specificity of 91.57%, which outperforms nearly all the published algorithms when applied in the context of a similar global training approach.

  4. 21st Century extravehicular activities: Synergizing past and present training methods for future spacewalking success

    Neil Armstrong's understated words, "That's one small step for man, one giant leap for mankind" were spoken from Tranquility Base forty years ago. Even today, those words resonate in the ears of millions, including many who had yet to be born when man first landed on the surface of the moon. By their very nature, and in the true spirit of exploration, extravehicular activities (EVAs) have generated much excitement throughout the history of manned spaceflight. From Ed White's first spacewalk in the June of 1965, to the first steps on the moon in 1969, to the expected completion of the International Space Station (ISS), the ability to exist, live and work in the vacuum of space has stood as a beacon of what is possible. It was NASA's first spacewalk that taught engineers on the ground the valuable lesson that successful spacewalking requires a unique set of learned skills. That lesson sparked extensive efforts to develop and define the training requirements necessary to ensure success. As focus shifted from orbital activities to lunar surface activities, the required skill set and subsequently the training methods changed. The requirements duly changed again when NASA left the moon for the last time in 1972 and have continued to evolve through the SkyLab, Space Shuttle, and ISS eras. Yet because the visits to the moon were so long ago, NASA's expertise in the realm of extra-terrestrial EVAs has diminished. As manned spaceflight again shifts its focus beyond low earth orbit, EVA's success will depend on the ability to synergize the knowledge gained over 40+ years of spacewalking to create a training method that allows a single crewmember to perform equally well, whether performing an EVA on the surface of the Moon, while in the vacuum of space, or heading for a rendezvous with Mars. This paper reviews NASA's past and present EVA training methods and extrapolates techniques from both to construct the basis for future EVA astronaut training.

  5. A nonlinear training set superposition filter derived by neural network training methods for implementation in a shift-invariant optical correlator

    The various types of synthetic discriminant function (sdf) filter result in a weighted linear superposition of the training set images. Neural network training procedures result in a non-linear superposition of the training set images or, effectively, a feature extraction process, which leads to better interpolation properties than achievable with the sdf filter. However, generally, shift invariance is lost since a data dependant non-linear weighting function is incorporated in the input data window. As a compromise, we train a non-linear superposition filter via neural network methods with the constraint of a linear input to allow for shift invariance. The filter can then be used in a frequency domain based optical correlator. Simulation results are presented that demonstrate the improved training set interpolation achieved by the non-linear filter as compared to a linear superposition filter.

  6. The value of haptic feedback in conventional and robot-assisted minimal invasive surgery and virtual reality training: a current review.

    Virtual reality (VR) as surgical training tool has become a state-of-the-art technique in training and teaching skills for minimally invasive surgery (MIS). Although intuitively appealing, the true benefits of haptic (VR training) platforms are unknown. Many questions about haptic feedback in the different areas of surgical skills (training) need to be answered before adding costly haptic feedback in VR simulation for MIS training. This study was designed to review the current status and value of haptic feedback in conventional and robot-assisted MIS and training by using virtual reality simulation. A systematic review of the literature was undertaken using PubMed and MEDLINE. The following search terms were used: Haptic feedback OR Haptics OR Force feedback AND/OR Minimal Invasive Surgery AND/OR Minimal Access Surgery AND/OR Robotics AND/OR Robotic Surgery AND/OR Endoscopic Surgery AND/OR Virtual Reality AND/OR Simulation OR Surgical Training/Education. The results were assessed according to level of evidence as reflected by the Oxford Centre of Evidence-based Medicine Levels of Evidence. In the current literature, no firm consensus exists on the importance of haptic feedback in performing minimally invasive surgery. Although the majority of the results show positive assessment of the benefits of force feedback, results are ambivalent and not unanimous on the subject. Benefits are least disputed when related to surgery using robotics, because there is no haptic feedback in currently used robotics. The addition of haptics is believed to reduce surgical errors resulting from a lack of it, especially in knot tying. Little research has been performed in the area of robot-assisted endoscopic surgical training, but results seem promising. Concerning VR training, results indicate that haptic feedback is important during the early phase of psychomotor skill acquisition.

    In this paper a new method based on discrete wavelet transform and correlation coefficient is presented for digital differential protection. The algorithm includes offline and online operations. In offline operation, discrete wavelet transform is used to decompose typical three-phase differential currents for inrush current. Then an index is defined and computed. The index is based on the sum of the energy of detail coefficients at level 5 of three-phase differential currents at each half cycle. The online operation consists of capturing the three-phase differential currents using 10 kHz sampling rate, decomposing it by db1. Finally, the inrush current and internal fault is detected based on correlation coefficients of the computed index of pre-stored typical inrush current and a recorded indistinct signal. The effectiveness of the approach is tested using numerous inrush and internal fault currents. Simulations are used to confirm the aptness and the capability of the proposed method to discriminate inrush current from internal fault. (author)

    Fundoscopic examination is an essential component of the neurologic examination. Competence in its performance is mandated as a required clinical skill for neurology residents by the American Council of Graduate Medical Education. Government and private insurance agencies require its performance and documentation for moderate- and high-level neurologic evaluations. Traditionally, assessment and teaching of this key clinical examination technique have been difficult in neurology residency training. To evaluate the utility of a simulation-based method and the traditional lecture-based method for assessment and teaching of fundoscopy to neurology residents. This study was a prospective, single-blinded, education research study of 48 neurology residents recruited from July 1, 2015, through June 30, 2016, at a large neurology residency training program. Participants were equally divided into control and intervention groups after stratification by training year. Baseline and postintervention assessments were performed using questionnaire, survey, and fundoscopy simulators. After baseline assessment, both groups initially received lecture-based training, which covered fundamental knowledge on the components of fundoscopy and key neurologic findings observed on fundoscopic examination. The intervention group additionally received simulation-based training, which consisted of an instructor-led, hands-on workshop that covered practical skills of performing fundoscopic examination and identifying neurologically relevant findings on another fundoscopy simulator. The primary outcome measures were the postintervention changes in fundoscopy knowledge, skills, and total scores. A total of 30 men and 18 women were equally distributed between the 2 groups. The intervention group had significantly higher mean (SD) increases in skills (2.5 [2.3] vs 0.8 [1.8], P = .01) and total (9.3 [4.3] vs 5.3 [5.8], P = .02) scores compared with the control group.

    A cylindrical current method is developed to obtain a stable and precise electrical resistivity of a specimen with or without a coating film. The electrical resistivity of a standard silicon wafer doped with boron at a concentration can be measured using the proposed method if the experimental results of electrical voltage varying with the distance from the center line of the cylindrical current are available. A comparison of the electrical resistivity obtained using the present method and the theoretical reference value indicates that the proposed method produces reliable and precise measurements. Using four test samples, the experimental results of electrical resistivity measured by the present method are shown to be reproducible and more precise than those measured by the four-terminal sensing method and the van der Pauw method. The electrical voltage and current obtained at various distances from the center line of the cylindrical current are almost independent of the distance and the direction of measurements. The effect of specimen's crystallinity appears to be the governing factor of electrical resistivity. Electrical resistivity decreases with increasing crystallinity generally.

    Training in quality improvement (QI) is a pillar of the next accreditation system of the Accreditation Committee on Graduate Medical Education and a growing expectation of physicians for maintenance of certification. Despite this, many postgraduate medical trainees are not receiving training in QI methods. We created the Fellows Applied Quality Training (FAQT) curriculum for cardiology fellows using both didactic and applied components with the goal of increasing confidence to participate in future QI projects. Fellows completed didactic training from the Institute for Healthcare Improvement's Open School and then designed and completed a project to improve quality of care or patient safety. Self-assessments were completed by the fellows before, during, and after the first year of the curriculum. The primary outcome for our curriculum was the median score reported by the fellows regarding their self-confidence to complete QI activities. Self-assessments were completed by 23 fellows. The majority of fellows (15 of 23, 65.2%) reported no prior formal QI training. Median score on baseline self-assessment was 3.0 (range, 1.85-4), which was significantly increased to 3.27 (range, 2.23-4; P = 0.004) on the final assessment. The distribution of scores reported by the fellows indicates that 30% were slightly confident at conducting QI activities on their own, which was reduced to 5% after completing the FAQT curriculum. An interim assessment was conducted after the fellows completed didactic training only; median scores were not different from the baseline (mean, 3.0; P = 0.51). After completion of the FAQT, cardiology fellows reported higher self-confidence to complete QI activities. The increase in self-confidence seemed to be limited to the applied component of the curriculum, with no significant change after the didactic component.

    Greene, Samuel M; Batista, Victor S

    2017-09-12

    We introduce the "tensor-train split-operator Fourier transform" (TT-SOFT) method for simulations of multidimensional nonadiabatic quantum dynamics. TT-SOFT is essentially the grid-based SOFT method implemented in dynamically adaptive tensor-train representations. In the same spirit of all matrix product states, the tensor-train format enables the representation, propagation, and computation of observables of multidimensional wave functions in terms of the grid-based wavepacket tensor components, bypassing the need of actually computing the wave function in its full-rank tensor product grid space. We demonstrate the accuracy and efficiency of the TT-SOFT method as applied to propagation of 24-dimensional wave packets, describing the S1/S2 interconversion dynamics of pyrazine after UV photoexcitation to the S2 state. Our results show that the TT-SOFT method is a powerful computational approach for simulations of quantum dynamics of polyatomic systems since it avoids the exponential scaling problem of full-rank grid-based representations.

    Schwerman, Paul (Inventor)

    2017-01-01

    A circuit and method for controlling when a load may be fully energized includes directing electrical current through a current limiting resistor that has a first terminal connected to a source terminal of a field effect transistor (FET), and a second terminal connected to a drain terminal of the FET. The gate voltage magnitude on a gate terminal of the FET is varied, whereby current flow through the FET is increased while current flow through the current limiting resistor is simultaneously decreased. A determination is made as to when the gate voltage magnitude on the gate terminal is equal to or exceeds a predetermined reference voltage magnitude, and the load is enabled to be fully energized when the gate voltage magnitude is equal to or exceeds the predetermined reference voltage magnitude.

Furthermore, residents in programs offering a structured preclinical component performed significantly more procedures (P=0.012) using lasers than those in programs not offering a structured preclinical program. Devising new and innovative teaching methods is a clear avenue for future development in North American graduate periodontics programs.

  17. A method for state of energy estimation of lithium-ion batteries at dynamic currents and temperatures

    Liu, Xingtao; Wu, Ji; Zhang, Chenbin; Chen, Zonghai

    2014-12-01

    The state of energy (SOE) of Li-ion batteries is a critical index for energy optimization and management. In the applied battery system, the fact that the discharge current and the temperature change due to the dynamic load will result in errors in the estimation of the residual energy for the battery. To address this issue, a new method based on the Back-Propagation Neural Network (BPNN) is presented for the SOE estimation. In the proposed approach, in order to take into account the energy loss on the internal resistance, the electrochemical reactions and the decrease of the open-circuit voltage (OCV), the SOE is introduced to replace the state of charge (SOC) to describe the residual energy of the battery. Additionally, the discharge current and temperature are taken as the training inputs of the BPNN to overcome their interference on the SOE estimation. The simulation experiments on LiFePO4 batteries indicate that the proposed method based on the BPNN can estimate the SOE much more reliably and accurately.

    A contact-less method for determining transport critical current density and flux penetration depth in bulk superconductor material. A compressor having a hollow interior and a plunger for selectively reducing the free space area for distribution of the magnetic flux therein are formed of superconductor material. Analytical relationships, based upon the critical state model, Maxwell's equations and geometrical relationships define transport critical current density and flux penetration depth in terms of the initial trapped magnetic flux density and the ratio between initial and final magnetic flux densities whereby data may be reliably determined by means of the simple test apparatus for evaluating the current density and flux penetration depth.

    2015-01-01

    There are several problems in the Modular Multilevel Converter (MMC), such as the appearance of circulating current, capacitor voltage unbalance and the requirement for a high number of sensors. All these problems will decrease the reliability and raise the cost/uncertainty of using MMC solutions....... As a result, a sensorless control method is proposed in this paper, which targets to improve the performances of MMC in respect to the above mentioned disadvantages: To decrease the cost and simplify the physical implementation, a state observer is proposed and designed to estimate both the capacitor voltages...... and the circulating currents in order to replace the high numbers of sensors. Furthermore, a control method combining the circulating current suppression and the capacitor voltage balancing is conducted based on the proposed state observer. It is concluded that the proposed state observer and control method can...

  20. An Improved Distributed Secondary Control Method for DC Microgrids With Enhanced Dynamic Current Sharing Performance

    Energy Technology Data Exchange (ETDEWEB)

    Wang, Panbao; Lu, Xiaonan; Yang, Xu; Wang, Wei; Xu, Dianguo

    2016-09-01

    This paper proposes an improved distributed secondary control scheme for dc microgrids (MGs), aiming at overcoming the drawbacks of conventional droop control method. The proposed secondary control scheme can remove the dc voltage deviation and improve the current sharing accuracy by using voltage-shifting and slope-adjusting approaches simultaneously. Meanwhile, the average value of droop coefficients is calculated, and then it is controlled by an additional controller included in the distributed secondary control layer to ensure that each droop coefficient converges at a reasonable value. Hence, by adjusting the droop coefficient, each participating converter has equal output impedance, and the accurate proportional load current sharing can be achieved with different line resistances. Furthermore, the current sharing performance in steady and transient states can be enhanced by using the proposed method. The effectiveness of the proposed method is verified by detailed experimental tests based on a 3 × 1 kW prototype with three interface converters.

    1996-01-01

    The efficiency of the orthogonal least squares (OLS) method for training approximation networks is examined using the criterion of energy compaction. We show that the selection of basis vectors produced by the procedure is not the most compact when the approximation is performed using a nonorthogonal basis. Hence, the algorithm does not produce the smallest possible networks for a given approximation error. Specific examples are given using the Gaussian radial basis functions type of approximation networks.

    Tsujimoto, Tomiyuki; Nakade, Masahiko; Yagi, Yukihiro; Ishii, Noboru

    Water tree is one of the degradation aspects of XLPE cables used for under-ground distribution or transmission lines. We have developed the loss current method using 3rd harmonic in AC loss current for cable diagnosis. Harmonic components in loss current arise as a result of the non-linear voltage-current characteristics of water trees. We confirmed that the 3rd harmonic in AC loss current had good correlation with water tree growth and break down strength. After that, we have applied this method to the actual 66kV XLPE cable lines. Up to now, the number of the application results is more than 130 lines. In case of cable lines terminated at gas-insulated switchgear (GIS), we have to remove the lightning arrestor (LA) and the potential transformer (PT) out of the test circuit. The reason is that we are afraid that each of LA and PT disturbs the degradation signal from cable lines. It takes extra time (1 or 2 days) and costs more to remove LA and PT in GIS out of a circuit. In order to achieve easy and reasonable diagnosis, we have developed a new method for cable lines terminated at GIS, by utilizing a technique, which enables to reduce signal of LA and PT from disturbed signal of cable lines. We confirmed the effect of the new method by experiments with actual cables.

    All of the quantitative landslide susceptibility mapping (QLSM) methods requires two basic data types, namely, landslide inventory and factors that influence landslide occurrence (landslide influencing factors, LIF). Depending on type of landslides, nature of triggers and LIF, accuracy of the QLSM methods differs. Moreover, how to balance the number of 0 (nonoccurrence) and 1 (occurrence) in the training set obtained from the landslide inventory and how to select which one of the 1's and 0's to be included in QLSM models play critical role in the accuracy of the QLSM. Although performance of various QLSM methods is largely investigated in the literature, the challenge of training set construction is not adequately investigated for the QLSM methods. In order to tackle this challenge, in this study three different training set selection strategies along with the original data set is used for testing the performance of three different regression methods namely Logistic Regression (LR), Bayesian Logistic Regression (BLR) and Fuzzy Logistic Regression (FLR). The first sampling strategy is proportional random sampling (PRS), which takes into account a weighted selection of landslide occurrences in the sample set. The second method, namely non-selective nearby sampling (NNS), includes randomly selected sites and their surrounding neighboring points at certain preselected distances to include the impact of clustering. Selective nearby sampling (SNS) is the third method, which concentrates on the group of 1's and their surrounding neighborhood. A randomly selected group of landslide sites and their neighborhood are considered in the analyses similar to NNS parameters. It is found that LR-PRS, FLR-PRS and BLR-Whole Data set-ups, with order, yield the best fits among the other alternatives. The results indicate that in QLSM based on regression models, avoidance of spatial correlation in the data set is critical for the model's performance.

  9. Limitations of absolute current densities derived from the Semel & Skumanich method

    Institute of Scientific and Technical Information of China (English)

    2009-01-01

    Semel and Skumanich proposed a method to obtain the absolute electric current density, |Jz|, without disambiguation of 180° in the transverse field directions. The advantage of the method is that the uncertainty in the determination of the ambiguity in the magnetic azimuth is removed. Here, we investigate the limits of the calculation when applied to a numerical MHD model. We have found that the combination of changes in the magnetic azimuth with vanishing horizontal field component leads to errors, where electric current densities are often strong. Where errors occur, the calculation gives |Jz| too small by factors typically 1.2 - 2.0.

    Although a 12-month clinical internship is the traditional precursor to a radiation oncology residency, the continuance of this mandated training sequence has been questioned. This study was performed to evaluate the perceptions of current radiation oncology residents with respect to the value of their internship experience. A survey was sent to all US radiation oncology residents. Each was queried about whether they considered the internship to be a necessary prerequisite for a career as a radiation oncologist and as a physician. Preferences were listed on a Likert scale (1 = not at all necessary to 5 = absolutely necessary). Seventy-one percent considered the internship year mostly (Likert Scale 4) or absolutely necessary (Likert Scale 5) for their development as a radiation oncologist, whereas 19.1% answered hardly or not at all (Likert Scale 2 and 1, respectively). With respect to their collective considerations about the impact of the internship year on their development as a physician, 89% had a positive response, 5.8% had a negative response, and 4.7% had no opinion. Although both deemed the preliminary year favorably, affirmative answers were more frequent among erstwhile internal medicine interns than former transitional program interns. A majority of radiation oncology residents positively acknowledged their internship for their development as a specialist and an even greater majority valued it for their development as a physician. This affirmative opinion was registered more frequently by those completing an internal medicine internship compared with a transitional internship.

    This study investigated the current knowledge and practices of general medical practitioners (GMPs) in Ireland regarding the examination of the oral cavity and the detection of oral malignancy and the training they had received at both undergraduate and postgraduate level and since commencing in practice. A questionnaire survey of GMPs in Ireland was conducted. One hundred and fifty four (65.3%) of the practitioners reported regularly examining the oral mucosa of their patients. Almost half of these (n=68) further qualified this response by stating that they only examined the oral mucosa if the patient reported pain in this area or if the patient specifically requested an oral examination for some reason. Eighty one (34.3%) practitioners surveyed felt confident in their ability to detect oral malignancies with the remaining two thirds unsure of whether they would be able to detect oral cancer. There was a significant association between the undergraduate and postgraduate teaching on examination of the oral cavity and whether practitioners felt confident in their ability to detect oral cancer [chi(2)(1)=4.811, p<0.05]. A statistically significant association was also found between the undergraduate and postgraduate teaching on the diagnosis of oral malignant disease and whether practitioners felt confident in their ability to detect oral cancer [chi(2)(1)=6.194, p<0.05]. In conclusion the level of knowledge of Irish general medical practitioners needs to be addressed with appropriate initiatives both at undergraduate level and via CME.

    The Prony method for spectrum estimation was combined with an adaptive frequency tracking and current frequency demultiplication method as a harmonic detection system. An injective active power filter was used for effective harmonic wave management. The automated system includes a digital signal processor and a high-speed interfacing device. An algorithm was developed to consider the slow voltage changes in the power grid as well as potential mutations in current harmonics. Widrow-Hoff's LMS algorithm was used to develop rolling steps for the filter. The method was used to detect harmonic waves with a sampling frequency of 400 Hz. Results of the study showed that the detection method can be used in real time to detect fundamental and first harmonics in electric power grids. 10 refs., 2 tabs., 1 fig.

    In this paper, we present a method used to the numeral eddy current sensor modeling based on genetic neural network to settle its nonlinear problem. The principle and algorithms of genetic neural network are introduced. In this method,the nonlinear model parameters of the numeral eddy current sensor are optimized by genetic neural network (GNN) according to measurement data. So the method remains both the global searching ability of genetic algorithm and the good local searching ability of neural network. The nonlinear model has the advantages of strong robustness, on-line scaling and high precision. The maximum nonlinearity error can be reduced to 0.037% using GNN. However, the maximum nonlinearity error is 0.075% using least square method (LMS).

    Numerous arguments in the recent neuroscientific literature support the use of musical training as a therapeutic tool among the arsenal already available to therapists and educators for treating children with dyslexia. In the present study, we tested the efficacy of a specially-designed Cognitivo-Musical Training (CMT) method based upon three principles: (1) music-language analogies: training dyslexics with music could contribute to improve brain circuits which are common to music and language processes; (2) the temporal and rhythmic features of music, which could exert a positive effect on the multiple dimensions of the "temporal deficit" characteristic of some types of dyslexia; and (3) cross-modal integration, based on converging evidence of impaired connectivity between brain regions in dyslexia and related disorders. Accordingly, we developed a series of musical exercises involving jointly and simultaneously sensory (visual, auditory, somatosensory) and motor systems, with special emphasis on rhythmic perception and production in addition to intensive training of various features of the musical auditory signal. Two separate studies were carried out, one in which dyslexic children received intensive musical exercises concentrated over 18 h during 3 consecutive days, and the other in which the 18 h of musical training were spread over 6 weeks. Both studies showed significant improvements in some untrained, linguistic and non-linguistic variables. The first one yielded significant improvement in categorical perception and auditory perception of temporal components of speech. The second study revealed additional improvements in auditory attention, phonological awareness (syllable fusion), reading abilities, and repetition of pseudo-words. Importantly, most improvements persisted after an untrained period of 6 weeks. These results provide new additional arguments for using music as part of systematic therapeutic and instructional practice for dyslexic children.

    The School of Medicine, University of Saskatchewan curriculum promotes self-direction as one of its learning philosophies. The authors sought to identify changes in self-directed learning (SDL) readiness during training. Guglielmino's SDL Readiness Scale (SDLRS) was administered to five student cohorts (N = 375) at admission and the end of every year of training, 2006 to 2010. Scores were analyzed using repeated-measurement analysis. A focus group and interviews captured students' and instructors' perceptions of self-direction. Overall, the mean SDLRS score was 230.6; men (n = 168) 229.5; women (n = 197) 232.3, higher than in the average adult population. However, the authors were able to follow only 275 students through later years of medical education. There were no significant effects of gender, years of premedical training, and Medical College Admission Test scores on SDLRS scores. Older students were more self-directed. There was a significant drop in scores at the end of year one for each of the cohorts (P < .001), and no significant change to these SDLRS scores as students progressed through medical school. Students and faculty defined SDL narrowly and had similar perceptions of curricular factors affecting SDL. The initial scores indicate high self-direction. The drop in scores one year after admission, and the lack of change with increased training, show that the current educational interventions may require reexamination and alteration to ones that promote SDL. Comparison with schools using a different curricular approach may bring to light the impact of curriculum on SDL.

    Full Text Available Police safety and use of force decisions during critical incidents are an ongoing source of concern for both police practitioners and the public. Prior research in the area of police performance reveals that psychological and physiological stress responses during critical incidents can shape the outcome of the incident, either positively or negatively. The goal of this study was to test a training method to improve use of force decision making among police. This randomized controlled pilot study consisted of training officers to apply techniques to enhance psychological and physiological control during stressful critical incidents. Of a pool of 80 police officers, potential participants were invited based on equivalent age, years of experience, physiological characteristics (i.e., body mass index [BMI] and cardiovascular reactivity, and expertise. Results revealed that the intervention group displayed significantly better physiological control, situational awareness, and overall performance, and made a greater number of correct use of force decisions than officers in the control group (all ps < .01. The relevant improvements in use of force decision-making found in this pilot study indicate that this training method warrants further investigation. Improved use of force decision making directly translates into potential lifesaving decisions for police and the civilians they are working with.

    Full Text Available PURPOSE: Laparoscopy has certainly brought considerable benefits to patients, but laparoscopic surgery requires a set of skills different from open surgery, and learning in the operating room may increase surgical time, and even may be harmful to patients. Several training programs have been developed to decrease these potential prejudices. PURPOSES: to describe the laparoscopic training program for urological residents of the "Hospital das Clinicas" of the Sao Paulo Medical School, to report urological procedures that are feasible in dry and wet labs, and to perform a critical analysis of the cost-benefit relation of advanced laparoscopic skills laboratory. MATERIALS AND METHODS: The laparoscopic skill lab has two virtual simulators, three manual simulators, and four laparoscopic sets for study with a porcine model. The urology residents during their first year attend classes in the virtual and manual simulator and helps the senior urological resident in activities carried out with the laparoscopic sets. During the second year, the urological resident has six periods per week, each period lasting four hours, to perform laparoscopic procedures with a porcine model. Results: In a training program of ten weeks, one urological resident performs an average of 120 urological procedures. The most common procedures are total nephrectomy (30%, bladder suture (30%, partial nephrectomy (10%, pyeloplasty (10%, ureteral replacement or transuretero anastomosis (10%, and others like adrenalectomy, prostatectomy, and retroperitoneoscopy. These procedures are much quicker and caused less morbidity. CONCLUSION: Laparoscopic skills laboratory is a good method for achieving technical ability.

  8. An inverse finite element method for determining residual and current stress fields in solids

    2016-11-01

    The life expectancy of a solid component is traditionally predicted by assessing its expected stress cycle and comparing it to experimentally determined stress states at failure. The accuracy of this procedure is often compromised by unforeseen extremes in the loading cycle or material degradation. Residually stressed parts may either have longer or shorter lifespans than predicted. Thus, determination of the current state of stress (i.e., the residual stress in the absence of external loading) and material properties is particularly important. Typically, the material properties of a solid are determined by fitting experimental data obtained from the measured deformation response in the stress-free configuration. However, the characterization of the mechanical behavior of a residually stressed body requires, in principle, a method that is not restricted to specific constitutive models. Complementing a recently developed technique, known as the reversed updated Lagrangian finite element method (RULFEM), a new method called estimating the current state of stress (ECSS) is presented herein. ECSS is based on three-dimensional full-field displacement and force data of a body perturbed by small displacements and complements the first step of the incremental RULFEM method. The present method generates the current state of stress (or residual stress in the absence of external tractions) and the incremental elasticity tensor of each finite element used to discretize the deformable body. The validity of the ECSS method is demonstrated by two noise-free simulation cases.

    It is currently debated as to whether or not positive reinforcement training is enriching to captive animals. Although both husbandry training and environmental enrichment (EE) have been found to benefit animal welfare in captivity, to date, no systematic investigation has compared an animal's preference for performing a trained behavior to engaging freely with a stimuli provided as EE. In the current paper, we used four captive wolves to (1) test the efficacy of a paired-stimulus preference assessment to determine preference for engaging in a trained behavior as a choice; and to (2) use a paired-stimulus preference assessment to determine whether or not individuals prefer to engage in a previously trained behavior versus a previously encountered EE stimuli. Of the four subjects tested, visual inspection of the graphs revealed that two of the subjects preferred trained behavior stimuli and two of the subjects preferred EE stimuli; only one of the wolves had a statically higher preference for an EE stimulus over a trained behavior. We believe that letting the animals choose between these two events is the first step in answering the question of whether or not is training enriching, however more research needs to be done and suggestions for future research is discussed. © 2015 Wiley Periodicals, Inc.

    Laparoscopic surgery has many advantages,but it is difficult for a surgeon to achieve the necessary surgical skills.Recently,virtual training simulations have been gaining interest because they can provide a safe and efficient learning environment for medical students and novice surgeons.In this paper,we present a hybrid modeling method for simulating gallbladder removal that uses both the boundary element method (BEM) and the finite element method (FEM).Each modeling method is applied according to the deformable properties of human organs:BEM for the liver and FEM for the gallbladder.Connective tissues between the liver and the gallbladder are also included in the surgical simulation.Deformations in the liver and the gallbladder models are transferred via connective tissue springs using a mass-spring method.Special effects and techniques are developed to achieve realistic simulations,and the software is integrated into a custom-designed haptic interface device.Various computer graphical techniques are also applied in the virtual gallbladder removal laparoscopic surgery training.The detailed techniques and the results of the simulations are described in this paper.

  1. Method and system for training dynamic nonlinear adaptive filters which have embedded memory

    Rabinowitz, Matthew (Inventor)

    2002-01-01

    Described herein is a method and system for training nonlinear adaptive filters (or neural networks) which have embedded memory. Such memory can arise in a multi-layer finite impulse response (FIR) architecture, or an infinite impulse response (IIR) architecture. We focus on filter architectures with separate linear dynamic components and static nonlinear components. Such filters can be structured so as to restrict their degrees of computational freedom based on a priori knowledge about the dynamic operation to be emulated. The method is detailed for an FIR architecture which consists of linear FIR filters together with nonlinear generalized single layer subnets. For the IIR case, we extend the methodology to a general nonlinear architecture which uses feedback. For these dynamic architectures, we describe how one can apply optimization techniques which make updates closer to the Newton direction than those of a steepest descent method, such as backpropagation. We detail a novel adaptive modified Gauss-Newton optimization technique, which uses an adaptive learning rate to determine both the magnitude and direction of update steps. For a wide range of adaptive filtering applications, the new training algorithm converges faster and to a smaller value of cost than both steepest-descent methods such as backpropagation-through-time, and standard quasi-Newton methods. We apply the algorithm to modeling the inverse of a nonlinear dynamic tracking system 5, as well as a nonlinear amplifier 6.

    Although communicating effectively with patients receiving palliative care can be difficult, it may contribute to maintaining or enhancing patients' quality of life. Little is known about the effect of training general practitioners in palliative care-specific communication. We hypothesized that palliative care patients of general practitioners exposed to the 'Availability, Current issues and Anticipation' communication training programme would report better outcomes than patients of control general practitioners. To evaluate the effectiveness of the Availability, Current issues and Anticipation training programme for general practitioners on patient-reported outcomes. In a controlled trial, general practitioners followed the Availability, Current issues and Anticipation programme or were part of the control group. Patients receiving palliative care of participating general practitioners completed the Palliative Care Outcome Scale, the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 Palliative, the Rest & Peace Scale, the Patient Satisfaction Questionnaire-III and the Availability, Current issues and Anticipation Scale, at baseline and 12 months follow-up.

    2017-03-02

    Methods are provided for mitigating problems caused by sneak- paths current during memory cell access in gateless arrays. Example methods contemplated herein utilize adaptive-threshold readout techniques that utilize the locality and hierarchy properties of the computer memory system to address this sneak-paths problem. The method of the invention is a method for reading a target memory cell located at an intersection of a target row of a gateless array and a target column of the gateless array, the method comprising: -reading a value of the target memory cell; and -calculating an actual value of the target memory cell based on the read value of the memory cell and a component of the read value caused by sneak path current. Utilizing either an "initial bits" strategy or a "dummy bits" strategy in order to calculate the component of the read value caused by sneak path current, example embodiments significantly reduce the number of memory accesses pixel for an array readout. In addition, these strategies consume an order of magnitude less power in comparison to alternative state-of-the-art readout techniques.

  11. Simulations of Transformer Inrush Current by Using BDF-Based Numerical Methods

    Directory of Open Access Journals (Sweden)

    Amir Tokić

    2013-01-01

    Full Text Available This paper describes three different ways of transformer modeling for inrush current simulations. The developed transformer models are not dependent on an integration step, thus they can be incorporated in a state-space form of stiff differential equation systems. The eigenvalue propagations during simulation time cause very stiff equation systems. The state-space equation systems are solved by using A- and L-stable numerical differentiation formulas (NDF2 method. This method suppresses spurious numerical oscillations in the transient simulations. The comparisons between measured and simulated inrush and steady-state transformer currents are done for all three of the proposed models. The realized nonlinear inductor, nonlinear resistor, and hysteresis model can be incorporated in the EMTP-type programs by using a combination of existing trapezoidal and proposed NDF2 methods.

    Bursts are electrical spikes firing with a high frequency, which are the most important property in synaptic plasticity and information processing in the central nervous system. However, bursts are difficult to identify because bursting activities or patterns vary with phys-iological conditions or external stimuli. In this paper, a simple method automatically to detect bursts in spike trains is described. This method auto-adaptively sets a parameter (mean inter-spike interval) according to intrinsic properties of the detected burst spike trains, without any arbitrary choices or any operator judgrnent. When the mean value of several successive inter-spike intervals is not larger than the parameter, a burst is identified. By this method, bursts can be automatically extracted from different bursting patterns of cultured neurons on multi-electrode arrays, as accurately as by visual inspection. Furthermore, significant changes of burst variables caused by electrical stimulus have been found in spontaneous activity of neuronal network. These suggest that the mean inter-spike interval method is robust for detecting changes in burst patterns and characteristics induced by environmental alterations.

  19. Implications of current educational policies in the Physical Education teachers’ training: a study on the teacher’s subjectivity

    Directory of Open Access Journals (Sweden)

    Matheus Bernardo Silva

    2015-01-01

    Full Text Available This paper seeks to problematize the ontology that underlies the official documents related to the physical education teachers’ training. The theoretical and methodological framework for such questioning is dialectical materialism. The reasoning of the official documents cited is confined to training “Competence”, linked to “reflective practice”. Explicitly or implicitly, such training policy seeks to meet the guidelines and requirements of flexible accumulation, in turn, based on productive restructuring, and its political expression, the neoliberalism. The teleologically oriented training towards such relations of production, although it seems avant-garde, is seeded by a conservatism that is evident in not facing social contradictions. The results revealed that the teachers’ subjectivity is limited in favor of an adaptive training to the alienation process.

    Research of adaptive individual and team-based training has been analyzed and helped find out that both in Russia and abroad, individual and team-based training and retraining of AASTM operators usually includes: production training, training of general computer and office equipment skills, simulator training including virtual simulators which use computers to simulate real-world manufacturing situation, and, as a rule, the evaluation of AASTM operators’ knowledge determined by completeness and adequacy of their actions under the simulated conditions. Such approach to training and re-training of AASTM operators stipulates only technical training of operators and testing their knowledge based on assessing their actions in a simulated environment.

    2016-01-01

    Fractional derivative formalism is proposed as the mathematical foundation of the polarization-depolarization current method for the diagnosis of dielectric isolation. Physical basis of the new approach is the observed deviation of the long-term relaxation from the Debye exponential law. We found that this behavior is consistent with the solution of the fractional differential equation: exponential behavior turns into the power dependence in the long-time asymptotics, and this part of the relaxation curve is more sensitive to the material state. The results of calculations for the polarization-depolarization currents in an oil-paper capacitor are in agreement with the specially performed experiments.

    2010-04-01

    We propose a landmine detection algorithm that uses ensemble discrete hidden Markov models with context dependent training schemes. We hypothesize that the data are generated by K models. These different models reflect the fact that mines and clutter objects have different characteristics depending on the mine type, soil and weather conditions, and burial depth. Model identification is based on clustering in the log-likelihood space. First, one HMM is fit to each of the N individual sequence. For each fitted model, we evaluate the log-likelihood of each sequence. This will result in an N x N log-likelihood distance matrix that will be partitioned into K groups. In the second step, we learn the parameters of one discrete HMM per group. We propose using and optimizing various training approaches for the different K groups depending on their size and homogeneity. In particular, we will investigate the maximum likelihood, and the MCE-based discriminative training approaches. Results on large and diverse Ground Penetrating Radar data collections show that the proposed method can identify meaningful and coherent HMM models that describe different properties of the data. Each HMM models a group of alarm signatures that share common attributes such as clutter, mine type, and burial depth. Our initial experiments have also indicated that the proposed mixture model outperform the baseline HMM that uses one model for the mine and one model for the background.

    The psychological impact of TBI is vast, leading to adverse effects on survivors and their caregivers. Unhealthy family functioning may be mitigated by therapeutic strategies, particularly interdisciplinary family systems approaches like the well-documented Brain Injury Family Intervention (BIFI). Little is known about the experience of providers who offer such interventions. This mixed methods study aims to demonstrate that a structured three-day training on the BIFI protocol improves providers' knowledge and confidence in working with survivors and families, and that this outcome is sustainable. Participants were 34 providers who participated in an intensive training and completed a web-based survey at four points of time. Quantitative data were analyzed via Wilcoxon signed-rank tests and binomial test of proportions. Qualitative data were analyzed according to rigorous coding procedures. Providers' knowledge of brain injury and their ability to conceptualize treatment models for survivors and their families increased significantly and mostly remain consistent over time. Qualitative data point to additional gains, such as understanding of family systems. Past studies quantify the BIFI as an evidence-based intervention. This study supports the effectiveness of training and serves as first to demonstrate the benefit for providers short- and long-term.

    Owing to the Benjamin-Feir instability,the Stokes wave train experiences a modulation-demodulation process,and presents a recurrence characteristics.Stiassnie and Shemer researched the unstable evolution process and provided a theoretical formulation for the recurrence period in 1985 on the basis of the nonlinear cubic Schr(o)dinger equation (NLS).However,NLS has limitations on the narrow band and the weak nonlinearity.The recurrence period is re-investigated in this paper by using a highly efficient High Order Spectral (HOS) method,which can be applied for the direct phaseresolved simulation of the nonlinear wave train evolution.It is found that the Stiassnie and Shemer's formula should be modified in the cases with most unstable initial conditions,which is important for such topics as the generation mechanisms of freak waves.A new recurrence period formula is presented and some new evolution characteristics of the Stokes wave train are also discussed in details.

  6. The transition matrix method for a 2D eddy current interaction problem

    Larsson, Lars; Rosell, Anders

    2012-05-01

    A 2D model of the eddy current interaction problem that consists of an inhomogeneity in a conductive half space is presented. The applied analytical method of solution is the transition (T) matrix method. This involves use of the free space Green's function to generate a system of boundary integral relations. In this way, it is easy to identify the contributions to the total solution from each different scattering surface. The different parts are separated also in the computation of the impedance. This leads to low cost simulations in terms of computation time and qualify the method to be used to obtain probability of detection (POD) curves. The T matrix method is a building block method and the possibility to extend the geometry with several inhomogeneities and extra layers will be discussed. The model is compared with a Finite Element (FE) model and numerical examples for the case with a cylindrical inhomogeneity are given.

  7. The cost of applying current helicopter external noise reduction methods while maintaining realistic vehicle performance

    Bowes, M. A.

    1978-01-01

    Analytical methods were developed and/or adopted for calculating helicopter component noise, and these methods were incorporated into a unified total vehicle noise calculation model. Analytical methods were also developed for calculating the effects of noise reduction methodology on helicopter design, performance, and cost. These methods were used to calculate changes in noise, design, performance, and cost due to the incorporation of engine and main rotor noise reduction methods. All noise reduction techniques were evaluated in the context of an established mission performance criterion which included consideration of hovering ceiling, forward flight range/speed/payload, and rotor stall margin. The results indicate that small, but meaningful, reductions in helicopter noise can be obtained by treating the turbine engine exhaust duct. Furthermore, these reductions do not result in excessive life cycle cost penalties. Currently available main rotor noise reduction methodology, however, is shown to be inadequate and excessively costly.

    Current teaching approaches in human and veterinary medicine across North America, Europe, and Australia include lectures, group discussions, feedback, role-play, and web-based training. Increasing class sizes, changing learning preferences, and economic and logistical challenges are influencing the design and delivery of communication skills in veterinary undergraduate education. The study's objectives were to (1) assess the effectiveness of small-group and web-based methods for teaching communication skills and (2) identify which training method is more effective in helping students to develop communication skills. At the Ross University School of Veterinary Medicine (RUSVM), 96 students were randomly assigned to one of three groups (control, web, or small-group training) in a pre-intervention and post-intervention group design. An Objective Structured Clinical Examination (OSCE) was used to measure communication competence within and across the intervention and control groups. Reliability of the OSCEs was determined by generalizability theory to be 0.65 (pre-intervention OSCE) and 0.70 (post-intervention OSCE). Study results showed that (1) small-group training was the most effective teaching approach in enhancing communication skills and resulted in students scoring significantly higher on the post-intervention OSCE compared to the web-based and control groups, (2) web-based training resulted in significant though considerably smaller improvement in skills than small-group training, and (3) the control group demonstrated the lowest mean difference between the pre-intervention/post-intervention OSCE scores, reinforcing the need to teach communication skills. Furthermore, small-group training had a significant effect in improving skills derived from the initial phase of the consultation and skills related to giving information and planning.

    Full Text Available Purpose. To define the characteristics of numerical calculations of mathematical model with one or more cyclic current voltage characteristics (CVC. This is an urgent problem, since any electric traction system device and electrified track in general, like non-linear passive or active two-terminal network in the present operating mode is described by current-voltage characteristic (CVC, which is based on the given input voltage and input current. Me-thodology. The electromagnetic process calculation in the power circuits of traction electric energy supply is the probabilistic task with solving nonlinear stochastic differential equations requiring for the development of special methods. Given the calculation difficulty, it is reasonable to perform them either by real CVC graph bypass or initially by applying its equivalent replacement with, for example, an ellipse. Findings. Numerical calculations of the mathematical model with one or more cyclic CVC can be performed by “real” CVC bypass or by "idealization" i. e. approximate replacement of real cyclic CVC. Originality. This paper presents the dynamic CVC of the DS3 and 2ES5K electric locomotives at different currents of electric locomotives. Practical value. Cyclic CVC normally and definitely can be applied in the system of electromagnetic state equations while transient state calculating in the traction system. Therefore while calculating the experimentally obtained CVC for the most “difficult and complex” (or/and the “easiest” mode is applied.

    Computing the electric eddy currents in non-linear materials, such as superconductors, is not straightforward. The design of superconducting magnets and power applications needs electromagnetic computer modeling, being in many cases a three-dimensional (3D) problem. Since 3D problems require high computing times, novel time-efficient modeling tools are highly desirable. This article presents a novel computing modeling method based on a variational principle. The self-programmed implementation uses an original minimization method, which divides the sample into sectors. This speeds-up the computations with no loss of accuracy, while enabling efficient parallelization. This method could also be applied to model transients in linear materials or networks of non-linear electrical elements. As example, we analyze the magnetization currents of a cubic superconductor. This 3D situation remains unknown, in spite of the fact that it is often met in material characterization and bulk applications. We found that below the penetration field and in part of the sample, current flux lines are not rectangular and significantly bend in the direction parallel to the applied field. In conclusion, the presented numerical method is able to time-efficiently solve fully 3D situations without loss of accuracy.

    The present work reviews the current fabrication methods of the functionally graded polymeric material (FGPM) and introduces a novel fabrication method that is versatile in applications as compared to those of existing used methods. For the first time electrophoresis was used to control the distribution of the tetracycline hydrochloride (TC) in a film made of polylactic acid (PLA), aiming to induce antimicrobial effect on the film prepared. The elemental analysis on the film surface showed that by employing electrophoresis force, higher amount of TC was detected near the top surface of the film. Results also showed that the FGPM samples with higher percentage of the TC on the film surface were highly effective to minimize the growth of Escherichia coli. These findings are useful and important to improve dispersion quality of the particles in the composite material and further enhance its antibacterial property.

    The paper describes a dual-frequency method for reducing the impact of changes in the gap size between the eddy-current transducer and the pipe, as well as the pipe electrical conductivity on the eddy-current thickness gauge readings. A block-diagram of the dual-frequency eddy-current thickness gauge is proposed for light-alloy drill pipes. The amplitude and signal phase dependencies on the wall thickness in the range from 6 to 17 mm and the gap in the range from 0 to 13.5 mm were studied, the results are presented. The digital signal processing algorithms based on the piecewise-linear approximation of low-frequency and high-frequency signal phase dependencies on the wall thickness are proposed. It is shown that the proposed correction algorithms can reduce the error caused by variations of electrical conductivity and the gap between the transducer and the pipe.

    To compare the immediate and delayed effects of implicit and explicit training methods for everyday skills in patients with dementia. Counterbalanced self-controlled cases series. Convenience sample of 10 patients with dementia (Mini-Mental State Examination score between 15 and 26) and 16 age- and education-matched controls. Two everyday tasks (using a microwave oven and a coffee machine) that were novel to all participants were trained in five 15-minute sessions. Each participant learned both tasks, one using an implicit learning method (modelling) and the other using an explicit learning method (providing verbal cues). Tasks and conditions were counterbalanced. The participants' performance was videotaped to assess how well the tasks were performed before training, after each training session, and 7-10 days after the final training session. A rater, who was blind to the training method used, scored the number of correctly executed steps by viewing the videotapes. The two training methods were effective in both the patient and healthy control groups, with there being a significant baseline-to-follow-up increase in the number of correctly completed steps (P dementia are able to acquire new skills that are relevant for daily life, showing a similar rate of learning regardless of whether implicit or explicit learning techniques are used.

  15. The value of value of information: best informing research design and prioritization using current methods.

    Eckermann, Simon; Karnon, Jon; Willan, Andrew R

    2010-01-01

    Value of information (VOI) methods have been proposed as a systematic approach to inform optimal research design and prioritization. Four related questions arise that VOI methods could address. (i) Is further research for a health technology assessment (HTA) potentially worthwhile? (ii) Is the cost of a given research design less than its expected value? (iii) What is the optimal research design for an HTA? (iv) How can research funding be best prioritized across alternative HTAs? Following Occam's razor, we consider the usefulness of VOI methods in informing questions 1-4 relative to their simplicity of use. Expected value of perfect information (EVPI) with current information, while simple to calculate, is shown to provide neither a necessary nor a sufficient condition to address question 1, given that what EVPI needs to exceed varies with the cost of research design, which can vary from very large down to negligible. Hence, for any given HTA, EVPI does not discriminate, as it can be large and further research not worthwhile or small and further research worthwhile. In contrast, each of questions 1-4 are shown to be fully addressed (necessary and sufficient) where VOI methods are applied to maximize expected value of sample information (EVSI) minus expected costs across designs. In comparing complexity in use of VOI methods, applying the central limit theorem (CLT) simplifies analysis to enable easy estimation of EVSI and optimal overall research design, and has been shown to outperform bootstrapping, particularly with small samples. Consequently, VOI methods applying the CLT to inform optimal overall research design satisfy Occam's razor in both improving decision making and reducing complexity. Furthermore, they enable consideration of relevant decision contexts, including option value and opportunity cost of delay, time, imperfect implementation and optimal design across jurisdictions. More complex VOI methods such as bootstrapping of the expected value of

    Full Text Available Suitable selection of the emergency alternatives is a critical issue in emergency response system of Unattended Train Operation (UTO metro system of China. However, there is no available method for dispatcher group in Operating Control Center (OCC to evaluate the decision under emergency situation. It was found that the emergency decision making in UTO metro system is relative with the preferences and the importance of multi-dispatcher in emergency. Regarding these factors, this paper presents a hybrid method to determinate the priority weights of emergency alternatives, which aggregates the preference matrix by constructing the emergency response task model based on the Weighted Ordered Weighted Averaging (WOWA operator. This calculation approach derives the importance weights depending on the dispatcher emergency tasks and integrates it into the Ordered Weighted Averaging (OWA operator weights based on a fuzzy membership relation. A case from train fire is given to demonstrate the feasibility and practicability of the proposed methods for Group Multi-Criteria Decision Making (GMCDM in emergency management of UTO metro system. The innovation of this research is paving the way for a systematic emergency decision-making solution which connects the automatic metro emergency response system with the GMCDM theory.

    Unnikrishnan, K P; Sastry, P S

    2007-01-01

    Discovering the 'Neural Code' from multi-neuronal spike trains is an important task in neuroscience. For such an analysis, it is important to unearth interesting regularities in the spiking patterns. In this report, we present an efficient method for automatically discovering synchrony, synfire chains, and more general sequences of neuronal firings. We use the Frequent Episode Discovery framework of Laxman, Sastry, and Unnikrishnan (2005), in which the episodes are represented and recognized using finite-state automata. Many aspects of functional connectivity between neuronal populations can be inferred from the episodes. We demonstrate these using simulated multi-neuronal data from a Poisson model. We also present a method to assess the statistical significance of the discovered episodes. Since the Temporal Data Mining (TDM) methods used in this report can analyze data from hundreds and potentially thousands of neurons, we argue that this framework is appropriate for discovering the `Neural Code'.

  1. A new method of CCD dark current correction via extracting the dark information from scientific images

    Ma, Bin; Hu, Yi; Liu, Qiang; Wang, Lifan; Wei, Peng

    2014-01-01

    We have developed a new method to correct dark current at relatively high temperatures for Charge-Coupled Device (CCD) images when dark frames cannot be obtained on the telescope. For images taken with the Antarctic Survey Telescopes (AST3) in 2012, due to the low cooling efficiency, the median CCD temperature was -46$^\\circ$C, resulting in a high dark current level of about 3$e^-$/pix/sec, even comparable to the sky brightness (10$e^-$/pix/sec). If not corrected, the nonuniformity of the dark current could even overweight the photon noise of the sky background. However, dark frames could not be obtained during the observing season because the camera was operated in frame-transfer mode without a shutter, and the telescope was unattended in winter. Here we present an alternative, but simple and effective method to derive the dark current frame from the scientific images. Then we can scale this dark frame to the temperature at which the scientific images were taken, and apply the dark frame corrections to the s...

  2. An improved current potential method for fast computation of stellarator coil shapes

    CERN Document Server

    Landreman, Matt

    2016-01-01

    Several fast methods for computing stellarator coil shapes are compared, including the classical NESCOIL procedure [Merkel, Nucl. Fusion 27, 867 (1987)], its generalization using truncated singular value decomposition, and a Tikhonov regularization approach we call REGCOIL in which the squared current density is included in the objective function. Considering W7-X and NCSX geometries, and for any desired level of regularization, we find the REGCOIL approach simultaneously achieves lower surface-averaged and maximum values of both current density (on the coil winding surface) and normal magnetic field (on the desired plasma surface). This approach therefore can simultaneously improve the free-boundary reconstruction of the target plasma shape while substantially increasing the minimum distances between coils, preventing collisions between coils while improving access for ports and maintenance. The REGCOIL method also allows finer control over the level of regularization, and it eliminates two pathologies of NE...

    2016-01-01

    Currently, analysis of various human body fluids is one of the most essential and promising approaches to enable the discovery of biomarkers or pathophysiological mechanisms for disorders and diseases. Analysis of these fluids is challenging due to their complex composition and unique characteristics. Development of new analytical methods in this field has made it possible to analyze body fluids with higher selectivity, sensitivity, and precision. The composition and concentration of analytes in body fluids are most often determined by chromatography-based techniques. There is no doubt that proper use of knowledge that comes from a better understanding of the role of body fluids requires the cooperation of scientists of diverse specializations, including analytical chemists, biologists, and physicians. This article summarizes current knowledge about the application of different chromatographic methods in analyses of a wide range of compounds in human body fluids in order to diagnose certain diseases and disorders.

    Full Text Available Background- Transcranial direct current stimulation (tDCS has been investigated mainly in adults and doses may not be appropriate in pediatric applications. In perinatal stroke where potential applications are promising, rational adaptation of dosage for children remains under investigation.Objective - Construct child-specific tDCS dosing parameters through case study within a perinatal stroke tDCS safety and feasibility trial. Methods- 10-year-old subject with a diagnosis of presumed perinatal ischemic stroke and hemiparesis was identified. T1 MRI scans used to derive computerized model for current flow and electrode positions. Workflow using modeling results and consideration of dosage in previous clinical trials was incorporated. Prior Ad hoc adult montages versus de novo optimized montages provided distinct risk benefit analysis. Approximating adult dose required consideration of changes in both peak brain current flow and distribution which further tradeoff between maximizing efficacy and adding safety factors. Electrode size, position, current intensity, compliance voltage, and duration were controlled independently in this process.Results- Brain electric fields modeled and compared to values previously predicted models. Approximating conservative brain current flow patterns and intensities used in previous adult trials for comparable indications, the optimal current intensity established was 0.7 mA for 10 minutes with a tDCS C3/C4 montage. Specifically 0.7 mA produced comparable peak brain current intensity of an average adult receiving 1.0 mA. Electrode size of 5x7 cm2 with 1.0 mA and low-voltage tDCS was employed to maximize tolerability. Safety and feasibility confirmed with subject tolerating the session well and no serious adverse events.Conclusion- Rational approaches to dose customization, with steps informed by computational modeling, may improve guidance for pediatric stroke tDCS trials.

    Evolutionary science is indispensable for understanding biological processes. Effective medical treatment must be anchored in sound biology. However, currently the insights available from evolutionary science are not adequately incorporated in either pre-medical or medical school curricula. To illuminate how evolution may be helpful in these areas, examples in which the insights of evolutionary science are already improving medical treatment and ways in which evolutionary reasoning can be practiced in the context of medicine are provided. In order to facilitate the learning of evolutionary principles, concepts derived from evolutionary science that medical students and professionals should understand are outlined. These concepts are designed to be authoritative and at the same time easily accessible for anyone with the general biological knowledge of a first-year medical student. Thus we conclude that medical practice informed by evolutionary principles will be more effective and lead to better patient outcomes.Furthermore, it is argued that evolutionary medicine complements general medical training because it provides an additional means by which medical students can practice the critical thinking skills that will be important in their future practice. We argue that core concepts from evolutionary science have the potential to improve critical thinking and facilitate more effective learning in medical training. © The Author(s) 2016.

    An approach combining boundary integral and finite element methods is introduced for the solution of three-dimensional inverse electromagnetic medium scattering problems. Based on the equivalence principle, unknown equivalent electric and magnetic surface current densities on a closed surface are utilized to decompose the inverse medium problem into two parts: a linear radiation problem and a nonlinear cavity problem. The first problem is formulated by a boundary integral equation, the computational burden of which is reduced by employing the multilevel fast multipole method (MLFMM). Reconstructed Cauchy data on the surface allows the utilization of the Lorentz reciprocity and the Poynting's theorems. Exploiting these theorems, the noise level and an initial guess are estimated for the cavity problem. Moreover, it is possible to determine whether the material is lossy or not. In the second problem, the estimated surface currents form inhomogeneous boundary conditions of the cavity problem. The cavity problem is formulated by the finite element technique and solved iteratively by the Gauss–Newton method to reconstruct the properties of the object. Regularization for both the first and the second problems is achieved by a Krylov subspace method. The proposed method is tested against both synthetic and experimental data and promising reconstruction results are obtained.

    Microalgae cells have the potential to rapidly accumulate lipids, such as triacylglycerides that contain fatty acids important for high value fatty acids (e.g., EPA and DHA) and/or biodiesel production. However, lipid extraction methods for microalgae cells are not well established, and there is currently no standard extraction method for the determination of the fatty acid content of microalgae. This has caused a few problems in microlagal biofuel research due to the bias derived from different extraction methods. Therefore, this study used several extraction methods for fatty acid analysis on marine microalga Tetraselmis sp. M8, aiming to assess the potential impact of different extractions on current microalgal lipid research. These methods included classical Bligh & Dyer lipid extraction, two other chemical extractions using different solvents and sonication, direct saponification and supercritical CO₂ extraction. Soxhlet-based extraction was used to weigh out the importance of solvent polarity in the algal oil extraction. Coupled with GC/MS, a Thermogravimetric Analyser was used to improve the quantification of microalgal lipid extractions. Among these extractions, significant differences were observed in both, extract yield and fatty acid composition. The supercritical extraction technique stood out most for effective extraction of microalgal lipids, especially for long chain unsaturated fatty acids. The results highlight the necessity for comparative analyses of microalgae fatty acids and careful choice and validation of analytical methodology in microalgal lipid research.

    Direct Current (DC) and Pulse current (PC) methods were used to get nanocrystalline Ni-ZrO2 composites from tri-ammonium citrate bath. In the electrocomposite formation, the ZrO2 particles were transported to the surface by mechanical action and got entrapped in the nickel matrix. Incorporation of ZrO2 in the nickel matrix was found to increase with current densities when DC was employed. Beyond 2 A/dm2, their incorporation became saturated when PC was used. PC method offered better electrocomposites than DC method producing finer grains and uniform surface. Scanning electron micrographs (SEM) reveals that smaller grains and uniform distribution of Zirconia particles in the nickel matrix. The increased hardness of Ni-ZrO2 electrocomposite coatings is due to incorporation of ZrO2 particles in the nickel matrix and also changes in grain size. Incorporation of ZrO2 particles in Ni-matrix favoured the enhanced microhardness and corrosion resistance of the deposit.

    A high-voltage direct-current (HVDC) transmission system includes an alternating current (AC) electrical source and a power converter channel that includes an AC-DC converter electrically coupled to the electrical source and a DC-AC inverter electrically coupled to the AC-DC converter. The AC-DC converter and the DC-AC inverter each include a plurality of legs that includes at least one switching device. The power converter channel further includes a commutating circuit communicatively coupled to one or more switching devices. The commutating circuit is configured to "switch on" one of the switching devices during a first portion of a cycle of the H-bridge switching circuits and "switch off" the switching device during a second portion of the cycle of the first and second H-bridge switching circuits.

    Here, we propose a training data selection method using a Support Vector Machine (SVM) to predict the effects of anticancer drugs. Conventionally, SVM is used for distinguishing between several types of data. However, in the method proposed here, the SVM is used to distinguish areas with only one or two types of data. The proposed method treats training data selection as an optimization problem and involves application of a genetic algorithm (GA). Moreover, GA with local search was applied to find the solution as the target problem was difficult to find. The composition method of GA for proposed method was examined. To determine its effectiveness, the proposed method was applied to an artificial anticancer drug data set. The verification results showed that the proposed method can be used to create a verifiable and predictable discriminant function by training data selection.

    We present results from a comparative study of student understanding for students who attended recitation classes that used different teaching methods. The purpose of the study was to evaluate which teaching methods would be the most effective for recitation classes associated with large lectures in introductory physics courses. Student volunteers from our introductory calculus-based physics course at the University of Cincinnati attended a special recitation class that was taught using one of four different teaching methods. A total of 272 students were divided into approximately equal groups for each method. Students in each class were taught the same topic, ``Changes in Energy and Momentum,'' from ``Tutorials in Introductory Physics'' by Lillian McDermott, Peter Shaffer and the Physics Education Group at the University of Washington. The different teaching methods varied in the amount of student and teacher engagement. Student understanding was evaluated through pretests and posttests. Our results demonstrate the importance of the instructor's role in teaching recitation classes. The most effective teaching method was for students working in cooperative learning groups with the instructors questioning the groups using Socratic dialogue. In addition, we investigated student preferences of modes of instruction through an open-ended survey. Our results provide guidance and evidence for the teaching methods which should be emphasized in training course instructors.

     We analyzed impression data and the scale of communication skills of students using text mining method to clarify which area a student was conscious of in communication in practical training. The results revealed that students tended to be conscious of the difference between practical hospital training and practical pharmacy training. In practical hospital training, specific expressions denoting relationships were "patient-visit", "counseling-conduct", "patient-counseling", and "patient-talk". In practical pharmacy training, specific expressions denoting relationships were "patient counseling-conduct", "story-listen", "patient-many", and "patient-visit". In practical hospital training, the word "patient" was connected to many words suggesting that students were conscious of a patient-centered communication. In practical pharmacy training, words such as "patient counseling", "patient", and "explanation" were placed in center and connected with many other words and there was an independent relationship between "communication" and "accept". In conclusion, it was suggested that students attempted active patient-centered communication in practical hospital training, while they were conscious of listening closely in patient counseling in practical pharmacy training.
