    Objective The National Lesbian, Gay, Bisexual, Transgender and Intersex (LGBTI) Ageing and Aged Care Strategy was introduced by the Commonwealth Government in 2012. The present study explored perceptions of the first Aged Care Champions (trained employees) of the opportunities, challenges and barriers to implementing the Strategy in Queensland.Methods The present study was an exploratory study of Champions who were nominated by their providers to build capacity around the Strategy for introduction into their organisations. The Champions (n = 62) were surveyed before commencing their training programs. Quantitative and qualitative material was collected on how the Champions perceived the introduction of the six standards within their organisation.Results Champions perceived that there were opportunities to improve inclusivity, leverage organisational support and increase training and support to staff. Key challenges identified were internal attitudes and values, a lack of resources and a need for training and networking. Significant barriers included a lack of management support, resistant staff and pre-existing prejudicial values.Conclusions Providers and practitioners can leverage the opportunity to increase organisational levels of inclusivity, demonstrate organisational support to improve outcomes for clients and stakeholders and, importantly, provide staff training and development critical to the successful implementation of the Strategy.What is known about the topic? Many LGBTI elders have faced a lived history of oppression and discrimination and have special health care needs. As they age, their needs for greater levels of care increase, but for many so to do their concerns about receiving equitable treatment.What does this paper add? The National LGBTI Ageing and Aged Care Strategy was introduced to address the concerns and needs of LGBTI elders and ensure inclusive and supportive care. This study explores the opportunities, challenges and barriers as

    Full Text Available On the basis of obtained results, we could assume that the level of explosive leg power infl uences on achieving top-class results in karate. A champion model (Stojadinov: shows that karate demands higher values of maximum jump, optimal energetic consumption and output, while it is achieved a maximum use of high values. It could be concluded that explosive leg power infl uences signifi cantly on achieving top-class sports results and it could infl uence notably on motion and technique choice which a competitor uses most frequently. It is obvious that without high level of explosive leg power there are no top-class results in karate, what indicates some former researches in karate. On the basis of former researches (Zulic 1987, 1989, Doder and collaborators 1998, 2000, 2001, 2003, 2005 top-class karate players (seniors and pioneers with higher explosive leg power showed better results in accomplishing of karate technique. That means that harmonic power canon of a mentioned sample of our best karate players in struggles as well as a model of our best karate players on European and World Championships could be considered as a universal model of a relation between dynamometric power of some muscular groups, which by suitable assumptions and other factors from an equation of a success specifi cation in this sport, provides the best condition for achieving maximum values in karate battles.

    Full Text Available Any conventional learning process involves the traditional hierarchy of garnering of information and then recall gathered information. Constructive learning is an important research area having wide impact on teaching methods in education, learning theories, and plays a major role in many education reform movements. It is observed that constructive learning advocates the interconnection between emotions and learning. Human teachers identify the emotions of students with varying degrees of accuracy and can improve the learning rate of the students by motivating them. In learning with computers, computers also should be given the capability to recognize emotions so as to optimize the learning process. Image Processing is a very popular tool used in the process of establishing the theory of Constructive Learning. In this paper we use the Optical Flow computation in image sequences to analyze the accuracy of the moves of a karate player. We have used the Lucas-Kanade method for computing the optical flow in image sequences. A database consisting of optical flow images by a group of persons learning karate is formed and the learning rates are analyzed in order to main constructive learning. The contours of flow images are compared with the standard images and the error graphs are plotted. Analysis of the emotion of the amateur karate player is made by observing the error plots.

    Full Text Available In this paper we propose a novel algorithm that enables online actions segmentation and classification. The algorithm enables segmentation from an incoming motion capture (MoCap data stream, sport (or karate movement sequences that are later processed by classification algorithm. The segmentation is based on Gesture Description Language classifier that is trained with an unsupervised learning algorithm. The classification is performed by continuous density forward-only hidden Markov models (HMM classifier. Our methodology was evaluated on a unique dataset consisting of MoCap recordings of six Oyama karate martial artists including multiple champion of Kumite Knockdown Oyama karate. The dataset consists of 10 classes of actions and included dynamic actions of stands, kicks and blocking techniques. Total number of samples was 1236. We have examined several HMM classifiers with various number of hidden states and also Gaussian mixture model (GMM classifier to empirically find the best setup of the proposed method in our dataset. We have used leave-one-out cross validation. The recognition rate of our methodology differs between karate techniques and is in the range of 81% ± 15% even to 100%. Our method is not limited for this class of actions but can be easily adapted to any other MoCap-based actions. The description of our approach and its evaluation are the main contributions of this paper. The results presented in this paper are effects of pioneering research on online karate action classification.

    2012-04-01

    Full Text Available Assertiveness is the ability to express your thoughts, beliefs and opinions without the feeling of internal tension, that is why it is a desired trait of character. One of the examples of sports disciplines in which assertiveness can play a desired role is karate. One of the aims of this paper was to answer the question, whether the act of doing karate influences the level of assertiveness among people who practice it and to compare the results with the level of assertiveness declared by people who do other sports. The method applied in this paper was the diagnostics survey, while the tool was the questionnaire form based on the Rathus Assertiveness Scale. 50 students who practice karate on regular basis and 50 students who do other sports participated in the research. It is undeniable that the level of assertiveness among people who practice karate is higher in comparison to people who do other sports. Karate doers, both men and women obtained better results compared to the second group of sportsmen/women. This regularity can be observed among men, but it is more perceptible among women. As the research presents, people who attend karate trainings at least three times a week are characterized by a higher level of assertiveness in comparison to those who attend the training once a week.

    Full Text Available Clove may be looked upon as a champion of all the antioxidants known till date. The Oxygen Radical Absorption Capacity (ORAC test is a scale developed by U.S. Department of Agriculture for comparing anti-oxidant activity. The ORAC score, of clove is over 10 million. A drop of clove oil is 400 times more powerful as an anti-oxidant than wolf berries or blueberries. Health benefits from the use of clove have been known over the centuries. It is beneficial as a home remedy in curing several ailments / diseases. In addition to its culinary uses, the clove buds have an abundance of medicinal and recreational uses. The major part of the world’s consumption of the clove spice is in the home kitchens. However, commercial use of the clove is for the production of clove oil that contain active constituents, which possess antioxidant, anti-fungal, anti-viral, anti-microbial, anti-diabetic, anti-inflammatory, antithrombotic, anesthetic, pain reliving and insect repellent properties. Eugenol is the main constituent responsible for the medicinal properties of the clove bud. In the light of above, we thought it worthwhile to compile an up-to-date review article on clove covering its, synonyms, chemical constituents, phytopharmacology and medicinal uses.

    2013-03-01

    This work aims at automatically recognizing sequences of complex karate movements and giving a measure of the quality of the movements performed. Since this is a problem which intrinsically needs a 3D model, in this work we propose a solution taking as input sequences of skeletal motions that can derive from both motion capture hardware or consumer-level, off the shelf, depth sensing systems. The proposed system is constituted by four different modules: skeleton representation, pose classification, temporal alignment, and scoring. The proposed system is tested on a set of different punch, kick and defense karate moves executed starting from the simplest case, i.e. fixed static stances (heiko dachi) up to sequences in which the starting stances is different from the ending one. The dataset has been recorded using a single Microsoft Kinect. The dataset includes the recordings of both male and female athletes with different skill levels, ranging from novices to masters.

    2012-07-01

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

  6. Physical and physiological profile of elite karate athletes.

    2012-10-01

    This review focuses on the most important physical and physiological characteristics of karate athletes from the available scientific research. It has been established that karate's top-level performers require a high fitness level. Top-level male karate athletes are typified by low body fat and mesomorphic-ectomorphic somatotype characteristics. Studies dealing with body composition and somatotype of females are scarce. Aerobic capacity has been reported to play a major role in karate performance. It prevents fatigue during training and ensures the recovery processes during rest periods between two subsequent bouts of fighting activity within a fight and between two consecutive matches. It has been established that there is no significant difference between male and female kata (forms) and kumite (sparring/combat) athletes with regard to aerobic performance. Nevertheless, further studies are needed to support these findings. Concerning anaerobic performance, there is a difference in maximal power explored by the force-velocity test between national and international level karatekas (karate practitioners) but, for the maximum accumulated oxygen deficit test there is no difference between them. Muscle explosive power plays a vital role in a karateka's capacity for high-level performance. However, it has been revealed that vertical jump performance, maximal power and maximal velocity differed between national- and international-level karatekas. Moreover, it has been reported that karate performance relies more on muscle power at lower loads rather than higher ones. Thus, karate's decisive actions are essentially dependent on muscle explosive power in both the upper and lower limbs. With regard to dynamic strength, limited research has been conducted. The maximal absolute bench press, half-squat one-repetition maximum and performance of isokinetic tasks differed significantly between highly competitive and novice male karatekas. Studies on female karate athletes do

    This study aimed to evaluate the relationship between physiological, and parameters of performance analysis during karate contest. Nine elite-level karate athletes participated in this study. Saliva sample was collected pre- and post-karate combat. Salivary cortisol (sC) post-combat 2 raised significantly compared to that recorded at pre-combat 1 (Δ%=105.3%; P=0.04; dz=0.78). The largest decrease of the salivary T/C ratio (sR) compared to pre-combat 1 was recorded post-combat 2 (Δ%=-43.5%; P=0.03). Moreover, blood lactate concentration post-combat 1 correlated positively to sCpost-combat 1 (r=0.66; P=0.05) and negatively to both salivary testosterone (sT) (r=-0.76; P=0.01) and sRpost-combat 1 (r=-0.76; P=0.01). There was no significant relationship between hormonal measures and parameters of match analysis. Although under simulated condition, karate combat poses large physiological stress to the karateka. Additionally, physiological strain to karate combat led to a catabolic hormonal response.

    Karate is a martial art that carries a high trauma risk. Trauma-related Swiss and European karate data are currently unavailable. This survey seeks to increase knowledge of the incidence of traumatic facial and dental injuries, their emergency management, awareness of tooth rescue boxes, the use of mouthguards and their modifications. Interviews were conducted with 420 karate fighters from 43 European countries using a standardized questionnaire. All the participants were semi-professionals. The data were evaluated with respect to gender, kumite level (where a karate practitioner trains against an adversary), and country. Of the 420 fighters interviewed, 213 had experienced facial trauma and 44 had already had dental trauma. A total of 192 athletes had hurt their opponent by inflicting a facial or dental injury, and 290 knew about the possibility of tooth replantation following an avulsion. Only 50 interviewees knew about tooth rescue boxes. Nearly all the individuals interviewed wore a mouthguard (n = 412), and 178 of them had made their own modifications to the guard. The results of the present survey suggest that more information and education in wearing protective gear are required to reduce the incidence of dental injuries in karate.

  9. Giuseppe Sergi, "champion" of Darwinism?

    Volpone, Alessandro

    2011-01-01

    The Italian anthropologist, psychologist and evolutionist Giuseppe Sergi (1841-1936) may be regarded in some respects today as an "atypical" Darwinist, but, almost paradoxically, he was considered a "champion" of Darwinism by colleagues and commentators of his own time. Probably, two aspects of his work are responsible for this apparent anomaly: his faith in the so-called soft inheritance and his claims regarding a theory concerning the polyphyletic origin of human races. The soft inheritance theory, however, was needed by Sergi to support ideas regarding the complexity of inheritance in man, a fact that, in his opinion, could not completely be put down to mechanical laws, and polygeny was useful when trying to rectify the problem concerning the incompleteness of the fossil record. In both cases, it is possible to show that he was involved in supporting Darwinian theory during the most severe crisis of its consensus in Italy and at International level, between the end of the 19th century and the beginning of the 20th. Finally, the apparent unorthodox features which can be found in Sergi's ideas appear to be, in Kuhnian terms, ad hoc hypotheses put forward by Sergi himself in order to support the paradigm.

    Full Text Available Sports in general, which, self-understandably, implies karate as well, be longs to that aspect of social improvement which focuses on satisfying individual and group needs, but those of a country too. Karate does not yield any material value, but it creates certain values important for the whole society which can be materialsed by other processes. Just like any other field of work, recruiting particular management personnel in karate is significant for indicating and positioning those needs that compel them to work in this very field. Therefore, one is certain: among the most significant factors that provoke activity are motives and attitudes. In today’s karate in Vojvodina particular managerial roles have not been well defined yet. The concept and strategy of a karate club as a basic organisational unit in sport is primarily based on knowledge, interests and motivation of a karate coach. Hence, there is a different motivational structure among those who are in karate.

    Full Text Available ResumoO objetivo deste estudo é interpretar os diferentes significados existentes nos emblemas/símbolos de estilos e escolas de Karate-Dō, analisando seus elementos internos e sua importância dentro dessa prática. Para sua realização, foram realizadas três etapas distintas: 1 catalogação e investigação dos estilos e escolas de Karate-Dō com maior representatividade histórica, cultural e política; 2 identificação dos símbolos utilizados por cada um desses estilos e escolas; e 3 análise de cada um desses símbolos. Essa análise torna-se importante para uma compreensão mais profunda dos diferentes significados envolvidos na prática do Karate-Dō, pois, apesar de seguirem um conjunto de valores comum a todos os Budō, as escolas possuem sua própria visão de mundo, utilizando seus símbolos para reforçar ou externar tais conceitos. A maior parte dos símbolos analisados demonstra um aprofundamento cultural em seus grafismos, sendo reconhecidos alguns elementos até de aspecto espiritual ou religioso. Esse simbolismo, em si, mostra um aspecto relevante para a compreensão do próprio fenômeno multicultural nomeado Karate-Dō.

    Full Text Available Cricket is becoming a fashionable team game throughout the world. One day internationals (ODI have been able to bring more and more spectators to the cricket ground, due to the nature of its’ format. Among the ODI tournaments, the Champions trophy takes a significant place, as it is the second largest tournament after the global event of cricket world cup. This paper investigates the performances of the bowlers who appeared in the 2013 Champions trophy. The main aim of this study is to identify the bowlers’ characteristics which impact their performances. The kernel resampling technique (KRT is implemented to analyze the collected sample (N=41 of the bowlers who played the Champions trophy in 2013. Findings of this study reveal that the bowlers’ prior economy rate and the height have influenced the performance significantly, while the handedness and the bowling style have not shown a statistical significance on their performances.

    The purpose of this study was to evaluate the effects of short-term increased hours of specific high-intensity karate training on motor skills in young karate athletes aged between 8 and 12 years. Seventy-three children, who regularly trained three karate sessions per-week were divided in two groups: high-intensity karate group (HG=53) and low-intensity karate group (LG=20). HG trained for 7 days: with two sessions per-day (one hour per-session) including specific karate techniques as well as coordination, balance, and flexibility exercises. LG, however, followed the same number of karate training sessions as before the beginning of the study (i.e., three sessions per-week with one hour per-session). Participants performed a battery of tests, 24 hours pre- and one week post-training: a medicine ball throw (MBT), standing long jump (SLJ), active joint flexibility (JM) and lateral/frontal jumps (JLT). Significant differences between results of pre and post karate training (ANOVA with repeated measures) included: MBT (Pkarate fitness component. In this regard, short term high-intensity karate training represents an effective method for enhancing muscular power and range of motion (i.e. flexibility) in young karate athletes aged between 8 and 12 years. Further studies are needed to support these findings with deeper data.

    Although it is well known that injuries occur in combat sports, the true incidence of concussions is not clearly defined in the literature for karate competition. To determine the incidence of concussions in top-level (World Karate Federation World Championships) karate competition. Injuries that took place in 4 consecutive World Karate Championships (from 2008 to 2014) were prospectively registered. A total of 4625 fights (2916 in the male category and 1709 in the female category) were scrutinised, and concussions were identified and analysed separately for frequency (rate per fight) and injury risk. A total of 4 concussions were diagnosed by the attending physicians after carrying out athlete examinations. Globally, there was 1 concussion in every 1156 fights, or 0.43/1000 athlete-exposures (AE). In male athletes, the rate of concussion was 1/5832 min of fighting, and in female athletes, it was 1/6836 min. OR for concussion in women is 0.57 (95% CI 0.06 to 5.47; z=0.489; p=0.6249) and risk ratio for concussions in men is RR 1.478 (95% CI 0.271 to 8.072), p=0.528, representing a higher risk of definite concussions in men than in women, but not statistically significant. There is not a significantly higher risk of concussions in team competition (no weight limit) when compared with individual competition (held with strict weight limits for each category). The risk of concussions in top-level karate competition is low, with a tendency for an increased risk for men and for competition without weight limits, but not statistically significant with respect to women or individual competition.

    It is known that boxers suffer a characteristic cumulative brain injury from repeated blows to the head that correlates well with the number of bouts fought. Much less is known about full-contact karate (kickboxing), which is relatively new. In full-contact karate, punches and kicks are actually landed, rather than being focused to culminate just short of an opponent, as practiced in traditional karate. Although a combatant can win on points, the surest means of victory is a knockout. Consequently, fighters strive to land blows to the head. To investigate the relative force of kicks and punches, a dummy head was mounted 175 cm above the floor (to simulate a 50th-percentile man standing erect) and 125 cm above the floor (to simulate the man in a crouched position) on a universal joint permitting motion about three axes. The mechanism was contrived to provide constant rotational stiffness, and springs provided constant restorative moments about the three axes. The texture of soft tissue was simulated by a mask of visco-elastic foamed materials. Fourteen karate experts punched and kicked the dummy. Accelerometer measurements in the 90- to 120-G range indicated that safety-chops (hand protectors) and safety-kicks (foot padding) did not reduce acceleration of the dummy. Ten-ounce boxing gloves mitigated peak acceleration to some extent. Kicks and punches produced accelerations in the same range. Violent acceleration of the head by any means produces injury. The authors conclude that, if full-contact karate is widely practiced, cases of kickboxer's encephalopathy will soon be reported.

    Background: Karate is one the most popular combat sports in the world. Physical fitness assessment on a regular manner is important for monitoring the effectiveness of the training program and the readiness of karatekas to compete. Objectives: The aim of this research was to examine the criterion related to validity of the karate specific aerobic test (KSAT) as an indicator of aerobic level of karate practitioners. Patients and Methods: Cardiorespiratory responses, aerobic performance level through both treadmill laboratory test and YoYo intermittent recovery test level 1 (YoYoIRTL1) as well as time to exhaustion in the KSAT test (TE’KSAT) were determined in a total of fifteen healthy international karatekas (i.e. karate practitioners) (means ± SD: age: 22.2 ± 4.3 years; height: 176.4 ± 7.5 cm; body mass: 70.3 ± 9.7 kg and body fat: 13.2 ± 6%). Results: Peak heart rate obtained from KSAT represented ~99% of maximal heart rate registered during the treadmill test showing that KSAT imposes high physiological demands. There was no significant correlation between KSAT’s TE and relative (mL/min kg) treadmill maximal oxygen uptake (r = 0.14; P = 0.69; [small]). On the other hand, there was a significant relationship between KSAT’s TE and the velocity associated with VO2max (vVO2max) (r = 0.67; P = 0.03; [large]) as well as the velocity at VO2 corresponding to the second ventilatory threshold (vVO2 VAT) (r = 0.64; P = 0.04; [large]). Moreover, significant relationship was found between TE’s KSAT and both the total distance covered and parameters of intermittent endurance measured through YoYoIRTL1. Conclusions: The KSAT has not proved to have indirect criterion related validity as no significant correlations have been found between TE’s KSAT and treadmill VO2max. Nevertheless, as correlated to other aerobic fitness variables, KSAT can be considered as an indicator of karate specific endurance. The establishment of the criterion related validity of the KSAT

    Objective The aim of the present study was to examine the influence of karate practice level (national vs international level) and sex (women vs men) on physiological and perceptual responses in three modern karate training modalities (tactical-technical (TT), technical-development (TD), and randori). Method The study included 18 karatekas participating in an eight-session training camp of four TT, two TD, and two randori. During each session, the percentage of maximal heart rate (HR), blood lactate concentration [La-], and rating of perceived exertion (RPE) were assessed. Results The main results showed that the percentage of maximal HR was significantly higher in women than in men regardless of practice level or training modality (70.3 ± 4.1 vs 66.2 ± 6.3, respectively). Moreover, [La-] and RPE were significantly lower in international-level karatekas compared with their national-level counterparts whatever the sex or training modality ([La-] = 11.4 ± 2.6 vs 8.3 ± 2.4 mmol · L-1 and RPE = 3.6 ± 1.2 vs 4.3 ± 1.5, respectively). Last, physiological and perceptual responses were significantly higher during randori in comparison with TT and TD for both sexes. Conclusion The combination of [La-] and RPE thus seems to be a good indicator for discriminating between national- and international-level karatekas, and randori seems to be an effective means to reproduce official karate sparring.

    The aim of the study was to assess interdependence of specific motor abilities (situation karate tests) and motor skills (karate techniques), and karate performance (fighting efficiency) in under-sixteen male karateka aged 11-12 and 13-14 years. A battery of 5 situation motor tests were applied and 6 basic elements of karate technique evaluated in a sample of 20 male karateka aged 11-12 and 20 male karateka aged 13-14 years. Three criterion variables were formed: 1) one factor as a factor of general technical efficiency in karate was isolated by factor analysis of 6 karate techniques; 2) cumulative evaluation of 2 kate as kate performance; and 3) total score assessment based on success achieved at national karate championships as contest efficiency (fighting efficiency). Regression analysis revealed the frequency of gedan barai blockade performance to be the superior predictor of technical efficiency, kate performance and contest success in karateka aged 11-12, whereas the speed of the gedan barai-jaku zuki (block-kick) combination performance and specific agility (sidewise mobility) were superior predictors of performance in karateka aged 13-14. Of the karate techniques (kicks) used, the quality of jaku zuki kick performance was the superior predictor of contest efficiency in karateka aged 11-12, and the quality of the jaku zuki-mawashi geri and kizame zuki-jaku zuki combination performance in karateka aged 13-14.

    The aim of this research was to determine the significance of morphological factors, factors of basic motor and specific motor abilities, and the factors of technical efficiency, on the karate fight success in Croatian female cadet karate athletes. With this purpose, the group of 18 anthropometric measures, 10 basic motor tests, 5 situational karate motor tests, the group of 8 evaluations of 6 basic karate techniques, and 2 karate kata performances was applied on the sample of 101 Croatian karateka aged 14 to 16. Inside the morphological area, the factor analysis isolated: Body mass and volume factor, Subcutaneous fat tissue factor, Longitudinal skeleton dimensionality factor, and Transversal fist dimensionality factor; in the basic motor area: General motor efficiency factor; in the situational motor area: General specific motor efficiency factor; in the area of karate technique performance evaluation: General technical efficiency factor. After that, the application of canonical discriminative analysis determined the differences between high and lower quality karate athletes in the overall area of the isolated factors. The discriminative function showed that high quality female karate athletes compared to those of lower quality differ the most in higher technical efficiency, higher basic and specific motor efficiency, while having somewhat less fat tissue and somewhat wider wrist and fist diameter.

    Purpose Investigate the physiological responses and rating of perceived exertion (RPE) in elite karate athletes and examine the relationship between a subjective method (Session-RPE) and two objective heart-rate (HR)-based methods to quantify training-load (TL) during international karate competition. Methods Eleven karatekas took part in this study, but only data from seven athletes who completed three matches in an international tournament were used (four men and three women). The duration of combat was 3 min for men and 2 min for women, with 33.6±7.6 min for the first interval period (match 1–2) and 14.5±3.1 min for the second interval period (match 2–3). HR was continuously recorded during each combat. Blood lactate [La-] and (RPE) were measured just before the first match and immediately after each match. Results Means total fights time, HR, %HRmax, [La-], and session-RPE were 4.7±1.6 min, 182±9 bpm, 91±3%, 9.02±2.12 mmol.L-1 and 4.2±1.2, respectively. No significant differences in %HRmax, [La-], and RPE were noticed across combats. Significant correlations were observed between RPE and both resting HR (r=0.60; P=0.004) and mean HR (r=0.64; P=0.02), session-RPE and Banister training-impulse (TRIMP) (r=0.84; Pkarate competition elicited near-maximal cardiovascular responses and high [La-]. Training should therefore include exercise bouts that sufficiently stimulate the zone between 90 and 100% HRmax. Karate coaches could use the RPE-method to follow competitor's competition loads and consider it in their technical and tactical training. PMID:24800001

A single-pulse TMS was applied using a figure-eight coil stimulator. Resting motor threshold (rMT was determined. Surface electromyography was recorded from the first dorsal interosseous muscle. Motor evoked potential (MEP latencies and amplitudes at rMT, 110%, and 120% of rMT were considered. Functional assessment of the coordination performance was assessed by in-phase (IP and anti-phase (AP homolateral hand and foot coordination tasks performed at 80, 120, and 180 bpm.Compared to controls, athletes showed lower rMT (p<0.01, shorter MEP latency (p<0.01 and higher MEP amplitude (p<0.01, with a significant correlation (r = 0.50, p<0.01 between rMT and MEP latency. Coordination decreased with increasing velocity, and better IP performances emerged compared to AP ones (p<0.001. In general, a high correlation between rMT and coordination tasks was found for both IP and AP conditions.With respect to controls, karate athletes present a higher corticospinal excitability indicating the presence of an activity-dependent alteration in the balance and interactions between inhibitory and facilitatory circuits determining the final output from the M1. Furthermore, the high correlation between corticospinal excitability and coordination performance could support sport-specific neurophysiological arrangements.

    Radio signal delays associated with the neutral atmosphere are one of the major error sources of space geodesy such as GPS, GLONASS, GALILEO, VLBI, In-SAR measurements. We have developed a state-of-art tool to estimate the atmospheric path delays by ray-tracing through JMA meso-scale analysis (MANAL data) data. The tools, which we have named 'KAshima RAytracing Tools (KARAT)', are capable of calculating total slant delays and ray-bending angles considering real atmospheric phenomena. Numerical weather models such as MANAL data have undergone a significant improvement of accuracy and spatial resolution, which makes it feasible to utilize them for the correction of atmosphere excess path delays. In the previous studies for evaluating KARAT performance, the KARAT solutions are slightly better than the solutions using VMF1 and GMF with linear gradient model for horizontal and height positions. Based on these results we have started the web-based online service, 'KAshima RAytracing Service (KARATS)' for providing the atmospheric delay correction of RINEX files on Jan 27th, 2010. The KARATS receives user's RINEX data via a proper web site (http://vps.nict.go.jp/karats/index.html) and processes user's data files using KARAT for reducing atmospheric slant delays. The reduced RINEX files are archived in the specific directory for each user on the KARATS server. Once the processing is finished the information of data archive is sent privately via email to each user. If user want to process a large amount of data files, user can prepare own server which archives them. The KARATS can get these files from the user's server using GNU ¥emph{wget} and performs ray-traced corrections. We will present a brief status of the KARATS and summarize first experiences gained after this service went operational in December 2009. In addition, we will also demonstrate the newest KARAT performance based on the 5km MANAL data which has been operational from April 7th, 2009 and an outlook on

    Summary Background: regular physical activity has an effect on biological responses in both muscles and organs that, in turn, alter the structure and functions of the brain. Therefore, this study aims at comparing motor (sprint, coordination ability and explosive legs strength skills) and cognitive abilities (working memory, attention, executive functioning) in children. Methods: 39 children with average chronological age of 9 years were divided in: Karatekas (n=19) and Sedentary (n=20) groups. Their abilities were measured by motor and cognitive tests. Motor skills were assessed through a battery composed by the 20 mt Sprint test, the Agility test and the Standing board jump Test. Cognitive profile was assessed by a battery of tests derived from BVN 5–11, “Batteria di Valutazione Neuropsicologica per l’Et à Evolutiva”: Visual discrimination test, Reaction time test, Forwards and Backwards Digit Span Tests, Corsi Block-Tapping test and Tower of London. Results: our results reveal significant differences between two groups (p < 0.05). Karate children show better speed times, explosive legs strength and coordination skills. They scored better on working memory, visual selective attention and executive functions. Conclusion: karate exercise training shows global benefits resulting in physiological and psychological gains in children. PMID:25332920

    Full Text Available The real-world experiences of young athletes follow a non-linear and dynamic trajectory and there is growing recognition that facing and overcoming a degree of challenge is desirable for aspiring elites and as such, should be recognized and employed. However, there are some misunderstandings of this talent needs trauma perspective with some research focusing excessively or incorrectly on the incidence of life and sport challenge as a feature of effective talent development. The objective of the study was to examine what factors associated with such trauma experiences may or may not discriminate between high, medium and low achievers in sport, classified as super-champions, champions or almosts. A series of retrospective interviews were used with matched triads (i.e., super-champions, champions or almosts of performers (N = 54 from different sports. Data collection was organized in three phases. In the first phase, a graphic time line of each performer’s career was developed. The second phase explored the specific issues highlighted by each participant in a chronological sequence. The third phase was a retrospective reflection on traumatic motivators, coach/significant other inputs and psychological challenges experienced and skills employed. Data suggested qualitative differences between categories of performers, relating to several perceptual and experiential features of their development. No evidence was found for the necessity of major trauma as a feature of development. There was a lack of discrimination across categories of performers associated with the incidence of trauma and, more particularly, life or non-sport trauma. These findings suggest that differences between levels of adult achievement relate more to what performers bring to the challenges than what they experience. A periodized and progressive set of challenge, preceded and associated with specific skill development, would seem to offer the best pathway to success for the

    Full Text Available This article, which falls within the scope of the sociology of sport, aims to study the perspective and understanding of martial and combat sports practitioners, especially of karate, in Portugal, on the concept of “Budo”. For this study, we used an extensive methodology and applied various techniques of social research (semi-directive interview, questionnaire survey. The sample was composed of 244 advanced karateka (brown and black belt at the national level. The results showed that karate practitioners conceive their practice as an expression of Budo, reproduced in a dominant way by teaching staff (trainers, through images, symbols and values. Karatekas gave special importance to the codes and standards of conduct associated with the ethical principles of Budô and the maintenance of the rites and symbols from the country of the Rising Sun. Karatekas who most valued Budo practiced the same karate style, therefore, the study may not be generalized to all practitioners of karate.

    Full Text Available The 1936 “masters meeting” sponsored by the Ryukyu Newspaper Company—a gathering of karate masters, journalists, and government leaders—gives us some indication of the political realities at play in Japan in the early decades of the 20th century and how they may have affected Okinawan karate. Tradition often seems as though it is a safeguard against change. However, the reality is that a resurgence of nationalism fed an anti-Chinese bias and an effort to assimilate Okinawan culture; both affected karate. With economic hardships in Okinawa and a desire to popularize karate, traditions did change. Some teachers sought ways to preserve traditional Okinawan martial arts within this changing political landscape. But at what cost?

    Full Text Available This study aims to find out the causes of propensity for elite athletes in universities in Turkey to take up karate branch, their expectations and reasons of involvement. A survey method was used in the study. The population for the study was made of elite students in universities engaged in karate. The measurement instrument was administered to 97 students. Data obtained from the survey was tested by Mann-Whitney U test and Kruskall-Wallis test. Elite athletes in karate branch in universities indicated that their families had more influence on their decision to take up this branch. Elite athletes in universities indicated that teachers of physical education and the press media have had almost no influence on their decision. Athletes considered the enjoyment of success as an important reason for engaging in karate, while joining a group of friends easily was considered unimportant. It was found that athletes in the national karate team had higher expectation than those not in the national team for enjoyment of success, obtaining material gains and being famed nationwide. It was further found out that as the length of time of involvement in karate increased, the desire increased for obtaining material gains, becoming famed, becoming a trainer, a referee, being famed nationwide, enjoying success and getting in the national team.

    Full Text Available Presently, coaches and researchers need to have a better comprehension of the kinesiological parameters that should be an important tool to support teaching methodologies and to improve skills performance in sports. The aim of this study was to (i identify the kinematic and neuromuscular control patterns of the front kick (mae-geri to a fixed target performed by 14 experienced karate practitioners, and (ii compare it with the execution of 16 participants without any karate experience, allowing the use of those references in the analysis of the training and learning process. Results showed that the kinematic and neuromuscular activity during the kick performance occurs within 600 ms. Muscle activity and kinematic analysis demonstrated a sequence of activation bracing a proximal-to-distal direction, with the muscles presenting two distinct periods of activity (1, 2, where the karateka group has a greater intensity of activation – root mean square (RMS and electromyography (EMG peak – in the first period on Rectus Femoris (RF1 and  Vastus Lateralis (VL1 and a lower duration of co-contraction in both periods on Rectus Femoris-Biceps Femoris and Vastus Lateralis-Biceps Femoris (RF-BF; VL-BF. In the skill performance, the hip flexion, the knee extension and the ankle plantar flexion movements were executed with smaller difference in the range of action (ROA in the karateka group, reflecting different positions of the segments. In conclusion, it was observed a general kinesiological pattern, which was similar in karateka and non-karateka practitioners. However, in the karateka group, the training induces a specialization in the muscle activity reflected in EMG and kinematic data, which leads to a better ballistic performance in the execution of the mae-geri kick, associated with a maximum speed of the distal segments, reached closer to the impact moment, possibly representing more power in the contact.

    For any real $x$ and any integer $k\\ge1$, we say that a set $\\mathcal{D}_{k}$ of $k$ distinct integers is a $k$-tuple jumping champion if it is the most common differences that occurs among $k+1$ consecutive primes less than or equal to $x$. For $k=1$, it's known as the jumping champion introduced by J. H. Conway. In 1999 A. Odlyzko, M. Rubinstein, and M. Wolf announced the Jumping Champion Conjecture that the jumping champions greater than 1 are 4 and the primorials 2, 6, 30, 210, 2310,.... They also made a weaker and possibly more accessible conjecture that any fixed prime $p$ divides all sufficiently large jumping champions. These two conjectures were proved by Goldston and Ledoan under the assumption of appropriate forms of the Hardy-Littlewood conjecture recently. In the present paper we consider the situation for any $k\\ge2$ and prove that any fixed prime $p$ divides every element of all sufficiently large $k$-tuple jumping champions under the assumption that the Hardy-Littlewood prime $k+1$-tuple conje...

    Full Text Available How students really use e-books is a subject of much interest to library professionals. This has particular relevance when it comes to selecting suppliers and e-book platforms for institutional use. The question of preferred formats (print versus digital has been asked exhaustively, but technology develops fast and is here to stay in higher education, so a more pressing question is how we evaluate which platforms offer the best user experience for our students. At the University of Exeter we used our student Library Champion volunteers as a focus group, repeating the process over two years, to help determine which platforms were preferred. Champions examined multiple interfaces, but concentrated primarily on aggregators. They were encouraged to use their own laptops and tablets to access the e-books, which proved particularly valuable as it allowed interfaces to be rated for their compatibility across devices. Positive and negative feedback was collated, sent to providers and also used directly to inform and alter the Library’s purchasing preference list.

    Full Text Available Karate is a fight practice that does not make use of weapons. It is based on old traditions and its main aim is to develop a sense of personality in the practitioner. Karate originated from unique spiritual and psychological dynamics, which are of utmost importance for the full understanding of this practice. The objective of this research is to analyze karate-do by means of its spirituality. This is because, together with the fundamental texts about the recent tradition of this fight, spirituality is considered to be the essence present in all dimensions of the artistic expression of karate. To this end, the historiographical methodology of phenomenological perspective was employed in this study. Karate-do has the spirituality of the empty hands method as the north of its body philosophy. Themes with blurred borders are analyzed from this spiritual point of view herein. This dynamics includes the subtractive fight, aiming at the fluid and intuitive understanding of reality.

    2015-07-01

    The purpose of this research was to identify the fighters' technical and tactical activity indicators in order to determine indicator significance regarding situational efficiency and designation between winning and losing performances in a karate match. We scientifically observed a sample of 274 male contesters of 137 karate matches during the 2008 World Karate Championship in Tokyo. Each individual competitor was observed in maximum of three matches. The matches were recorded using a DVD camera in order to collect data for further analysis, and the sample was further described using 48 technical and tactical indicators of situational efficiency and match outcome variables. The obtained results indicate that a karate match is composed of 91% of non-scoring techniques and 9% of scoring techniques in the total technique frequency. On this basis a significant difference in the situational efficiency between the match winners and the losing contesters has been discovered. Those two groups of fighters exhibit a statistically significant difference (pkarate match are in the largest extent defined by non-scoring techniques. Therefore, it would be a grave mistake to disregard non-scoring karate techniques in any future situational efficiency studies. It has been discovered that the winners differ from the defeated contesters by a higher level of situational efficiency in their executed techniques, which incorporate versatility, biomechanical and structural complexity, topological diversity and a specific tactical concept of technique use in the attack phase.

    This article describes the case of a 17-year-old adolescent boy who received a foot kick in the trunk area from an expert in karate. He presented with immediate cardiocirculatory arrest. After a prolonged resuscitation, he was transferred to a hospital where he died 5 days later without ever regaining consciousness. Postmortem investigations including autopsy, radiology, histology, toxicology, and postmortem chemistry were performed that showed signs of multiple organ failure, an acute hemorrhage in the region of the celiac plexus, and signs of medical resuscitation. No preexisting disease, particularly those concerning the heart, was objectified. The cause of death was attributed to multiple organ failure after a prolonged cardiocirculatory arrest. Concerning the origin of the cardiac arrest, 2 hypotheses were considered-a cardioinhibitory reflex and a cardiac contusion (commotio cordis). Because of the presence of traumatic lesions in the celiac plexus, the first hypothesis was finally submitted. This case is reported because rare cases of sudden death from celiac reflex are described in the literature where it is almost impossible to find references with accurate documentation. The presented case confirms the importance of detailed documentation of the circumstances and postmortem investigations to establish a diagnosis of death due to cardioinhibitory reflex.

    While imagery research has become popular in recent years, little research has specifically investigated differences in imagery ability between open- and closed-skill sport activities. The purpose of this study was to investigate whether the type of task, open or closed, affects vividness and controllability differently. Thirty female classic dancers (closed skill), 30 female karate athletes (open skill), and 30 female non-athlete students, between 14 and 20 years of age (M = 17.0, SD = 1.6), participated. They completed the Vividness of Visual Imagery Questionnaire, the Vividness of Movement Imagery Questionnaire, and the Subtraction of Parts Task. There was no difference in imagery ability between open- and closed-skill sport groups. Furthermore, dancers and karatekas had higher mean scores on imagery ability than the non-athlete group. A positive correlation was observed between the two questionnaires, supporting findings on the componential basis of imagery. This study contributed to increase the research in the specific area of open- and closed-skill sports and imagery ability.

    2006-01-01

    Objectives To evaluate the incidence and distribution of injuries in karate before and after the implementation of new rules established by the World Karate Federation in 2000. Methods Injury incidence was followed up during the official karate competition seasons of 1997 and 2002 in Croatia. A questionnaire was used to collect data on the age and sex of the competitor and localisation and severity of injury. Data were analysed separately for female and male competitors and age categories 98%) were categorised as mild (grade 1) in both periods studied. Conclusions The results of this study confirm the importance of the new competition rules in the distribution and prevention of injuries in martial arts. Strict judging and heavy penalties for uncontrolled blows, particularly for the youngest competitors, can significantly decrease the risk of injury. PMID:16556787

    Physician champions and leaders are essential to the success ofa CCIS implementation. Physician champions or leaders can be developed by recognizing the qualities of a leader and cultivating them. Finally, sustainable second-order change is facilitated bv a transformational leader--a leader who is charismatic, considers individual characteristics and needs of the constituency, and stimulates the constituency intellectually. A transformational leader does not accept the status quo but rather is continually questioning and offering constructive problem solutions. Transformational leadership may require more patience, time, tolerance, and resources, but it is worth the effort.

    We describe the design and development of an advanced reasoning framework employing semantic technologies, organized within a hierarchy of computational reasoning agents that interpret domain specific information. Designed based on an inspirational metaphor of the pattern recognition functions performed by the human neocortex, the CHAMPION reasoning framework represents a new computational modeling approach that derives invariant knowledge representations through memory-prediction belief propagation processes that are driven by formal ontological language specification and semantic technologies. The CHAMPION framework shows promise for enhancing complex decision making in diverse problem domains including cyber security, nonproliferation and energy consumption analysis.

  18. Enhanced HTS hit selection via a local hit rate analysis.

    2009-10-01

    The postprocessing of high-throughput screening (HTS) results is complicated by the occurrence of false positives (inactive compounds misidentified as active by the primary screen) and false negatives (active compounds misidentified as inactive by the primary screen). An activity cutoff is frequently used to select "active" compounds from HTS data; however, this approach is insensitive to both false positives and false negatives. An alternative method that can minimize the occurrence of these artifacts will increase the efficiency of hit selection and therefore lead discovery. In this work, rather than merely using the activity of a given compound, we look at the presence and absence of activity among all compounds in its "chemical space neighborhood" to give a degree of confidence in its activity. We demonstrate that this local hit rate (LHR) analysis method outperforms hit selection based on ranking by primary screen activity values across ten diverse high throughput screens, spanning both cell-based and biochemical assay formats of varying biology and robustness. On average, the local hit rate analysis method was approximately 2.3-fold and approximately 1.3-fold more effective in identifying active compounds and active chemical series, respectively, than selection based on primary activity alone. Moreover, when applied to finding false negatives, this method was 2.3-fold better than ranking by primary activity alone. In most cases, novel hit series were identified that would have otherwise been missed. Additional uses of and observations regarding this HTS analysis approach are also discussed.

    In this paper the results of KARATE-440 calculations on Novovoronezh NPP Recriticality Experiment are presented, the corresponding parameters are analyzed. The simulation of the processes and the comparison of the results with the measurements are of particular interest as these efforts make our code to be validated in a higher level. The KARATE-440 code system has been developed and applied for VVER-440 core analysis during near twenty years, as a close collaboration among the developers and the specialists at the 4 Hungarian nuclear power units. KARATE is now a mature, demonstrated, complete and integrated system of computer codes and procedures that provide full and independent VVER core analysis capabilities. Even if only some well defined states of the experiment were simulated, satisfactory agreement was found between measured and calculated data. The results present evidence that the KARATE- 440 code package can adequately model the reactor states in a wide range of performance parameters and the special core type referred in the experiment so it is acceptable for neutronic analysis of all the VVER-440 NPP's.

    KARATE TOURNAMENTS CONSIST OF TWO EQUALLY IMPORTANT KARATE DISCIPLINES: the kumite and kata competitions. Due to being based both on the distinctive selection of movement techniques and their kinematic and kinetic patterns, we hypothesized that the elite kumite and kata competitors could differ regarding their anthropometric and physical performance profiles. Thirty-one senior male karate competitors of the national karate team (kumite n = 19; kata n = 12) participated in this study. The tests applied included both the assessment of anthropometric (body height, mass and body mass index) and the following physical performance measurements: the adductor and hamstring flexibility (sideward leg splits test), speed and acceleration (20-m sprint test with 10-m acceleration time), explosive power (countermovement and standing triple jump), agility ("T"- test) and aerobic endurance (20-m multistage shuttle run test). The kumite competitors revealed a larger body size through body height (p = 0.01) and mass (p = 0.03), while the differences in body composition were non-significant. The kumite competitors also demonstrated higher acceleration (p = 0.03) and explosive power (standing triple jump; p = 0.03). A 6-7° higher flexibility of the kata competitors remained somewhat below the level of significance (p = 0.09). The findings could be interpreted by the distinctive differences in the movement techniques. Specifically, a higher explosive power could be beneficial for kumite, while both a smaller stature and higher flexibility (particularly of the lower extremity) could be important for the exceptionally low postures of the kata competitors. Although further elucidation is apparently needed, the obtained finding could be of importance for both the early selection and training of karate competitors.

    2013-01-01

    Purpose This study aimed to compare physiological responses and time-motion analysis between official and simulated karate combat. Methods Ten high-level karatekas participated in this study, which included official and simulated karate combat. Results Karatekas used more upper-limb attack techniques during official combat compared to simulated ones (6±3 vs 3±1; P=0.05, respectively). For official and simulated karate matches, the numbers of high-intensity actions (i.e. offensive and defensive fighting activity) were 14±6 and 18±5, respectively (P>0.05), lasting from <1s to 5s each. Total fighting activity phase was lower during official compared to simulated matches (21.0±8.2s vs 30.4±9.9s, P<0.01, respectively). Effort (10.0±2.8s) to rest (11.9±2.7s) ratio (E:R) was 1:1 and high-intensity actions (1.6±0.3s) to rest (11.9±2.7s) ratio was higher than 1:7 during simulated combat. During official karate match, the activity and rest duration were 10.0±3.4s and 16.2±4.1s, respectively (E:R ratio 1:1.5), while high-intensity actions were 1.5±0.3s, resulting in an E:R ratio of 1:11. Blood lactate concentration was higher during official (11.14±1.82 mmol.l-1) compared to simulated karate combat (7.80±2.66 mmol.l-1) (P<0.05). Subjective perceived exertion differed significantly between official and simulated combat (14±2 vs. 12±2; P<0.05, respectively). The majority of karatekas’ perceived exertion was higher in the lower limb muscle groups irrespective of the karate combat condition. Conclusion Official and simulated matches differ considerably, therefore coaches should create new strategies during training sessions to achieve the same effort and pause profile of competitive matches and/or that athletes should be submitted to frequent competitions to adapt themselves to the profile of this event.

    Nunan, David

    2006-01-01

    The purpose of the study was to develop an aerobic fitness assessment test for competitive Karate practitioners and describe the preliminary findings. Five well-trained, competitive Karate practitioners participated in this study. A protocol simulating common attack strikes used in competition Karate sparring was developed from video analysis. In addition, pilot testing established a specific sequence of strikes and timings to be used in the test. The time to perform the strike sequence remained the same, whilst the time between strike sequence performances was progressively reduced. The aim of the test was to increase intensity of exercise through a decrease in recovery. On two separate occasions, absolute and relative peak oxygen uptake (VO2peak), peak ventilation (VEpeak), maximum heart rate (HRM), and time to exhaustion (TE) obtained during the test were recorded. Subjective feedback provided by the participants was positive in that participants felt the test accurately simulated actions of a competitive sparring situation, and as a result athletes felt more motivated to perform well on this test. There was no significant between test difference in absolute VO2peak, relative VO2peak, HRM and TE (p > 0.05), indicating a potentially high reproducibility with the new test for these variables (test 1-test 2 difference of 0.04 L·min-1, 1 ml·kg-1·min-1, -3 beats·min-1, and 28 s; respectively). However, VEpeak displayed potentially less reproducibility due to a significant difference observed between tests (test 1- test 2 difference of -2.8 L·min-1, p < 0.05). There was a significant relationship between TE and relative VO2peak (R2 = 0.77, p < 0.001). Further developments to the test will need to address issues with work rate/force output assessment/monitoring. The new test accurately simulates the actions of competitive Karate sparring. Key Points This is the first attempt at an aerobic fitness test specific to competitive Karate practitioners Anecdotal reports

    2009-09-01

    Evidence-based dentistry champions are committed to improving the quality, effectiveness, and appropriateness of dental care through the application of evidence-based principles and tools. They share knowledge and skills to promote evidence-based dentistry (EBD) in practice, guiding colleagues, patients and policy makers in the application of critical thinking skills and evidence-based decision-making. Being an evidence-based champion requires furthering an understanding of the full process and the challenges of evidence based dentistry, including the development of an evidence base, evidence synthesis and summary, the creation of best practice guidelines, as well as evidence implementation. Efforts to improve the quality, effectiveness, and appropriateness of dental care need to occur at, and be coordinated across, multiple levels of dentistry, including the patient, clinician, team, organization, and policy.

    Laverack, Glenn

    2012-06-01

    For many years the World Health Organization (WHO) has provided the global direction and leadership that has helped to shape the way we view health promotion today. The future role of the WHO is now uncertain and the lack of global leadership for health promotion and identification of who will provide the future direction are issues that need to be addressed. The crucial question posed in this commentary is: Where are the individuals and organisations that will provide the global leadership and vision for health promotion in the future? We need named champions for the future leadership of health promotion practice - people and organisations who offer a leadership style that will maintain its global profile, be representative across sectors and have the ability to maintain its political efficacy. The two key health promotion approaches, top-down and bottom-up, do not always share the same goals, and they demand different styles of leadership. This is an important consideration in our goal to find champions who can work with both approaches and understand how to accommodate them as a part of the future direction of health promotion. This commentary raises key questions to stimulate discussion and action towards addressing the lack of global leadership in health promotion. It discusses some of the key players, leadership characteristics and the contradictions in style that are inherent in achieving a goal of charismatic global champions.

    A reliable fiber supply is critical to any papermaking operation. When Champion International Corp. opened its US$ 85 million deinking facility in Sheldon, TX, in March, it did so as the final step in a multiphase plan to supply its Sheldon newsprint mill with deinked pulp. With a capacity to convert 500 tons/day of old newspapers (ONP), glossy and colored newspaper advertising inserts, and magazines into 400 tons/day of deinked pulp, the company believes that this facility is capable of diverting 175,000 tpa of material from Texas landfills and saving the state more than 500,000 yard of landfill space annually. Together, Champion's Sheldon and Lufkin, TX, mills produce some 900,000 tpa of newsprint. Securing fiber sources and a transportation network to convey the fiber to the plant was no small task. Champion contracted with Texas cities, newspaper publishers, paper stock dealers, and waste haulers to buy and deliver newsprint. The company is also working with civic groups and social service organizations.

  19. Robust Hitting with Dynamics Shaping

    Science.gov (United States)

    Yashima, Masahito; Yamawaki, Tasuku

    The present paper proposes the trajectory planning based on “the dynamics shaping” for a redundant robotic arm to hit a target robustly toward the desired direction, of which the concept is to shape the robot dynamics appropriately by changing its posture in order to achieve the robust motion. The positional error of the end-effector caused by unknown disturbances converges onto near the singular vector corresponding to its maximum singular value of the output controllability matrix of the robotic arm. Therefore, if we can control the direction of the singular vector by applying the dynamics shaping, we will be able to control the direction of the positional error of the end-effector caused by unknown disturbances. We propose a novel trajectory planning based on the dynamics shaping and verify numerically and experimentally that the robotic arm can robustly hit the target toward the desired direction with a simple open-loop control system even though the disturbance is applied.

Prospective recording of the injuries resulting from all bouts in 3 consecutive World Karate Championships (2009, 2011, and 2013) for cadets was performed. Data were collected prospectively in situ with checklists that described competitor sex, bout category, and weight as well as injured area, diagnosis, mechanism of injury, severity, and treatment. A total of 1020 bouts were reviewed, 671 in the male category and 349 in the female category. A total of 61 injuries were recorded. Of those, only 3 were time-loss injuries. During the 2009 and 2011 championships, there was 1 injury per 25.6 fights, while during the 2013 championship the number of injuries increased, with 1 injury per 10 fights (P = .003). There was no statistical difference in the total injury rate between the male and female categories (P = .71), with an odds ratio of 1.16 (95% CI, 0.52-2.55). The injury rate for cadet top-level karate competition found in this prospective study is much lower than the rates previously published for karate or other martial arts competitions, but there seems to be a marked increase as more championships are held, which is a matter of concern. © 2015 The Author(s).

    2006-07-01

    Full Text Available The purpose of the study was to develop an aerobic fitness assessment test for competitive Karate practitioners and describe the preliminary findings. Five well-trained, competitive Karate practitioners participated in this study. A protocol simulating common attack strikes used in competition Karate sparring was developed from video analysis. In addition, pilot testing established a specific sequence of strikes and timings to be used in the test. The time to perform the strike sequence remained the same, whilst the time between strike sequence performances was progressively reduced. The aim of the test was to increase intensity of exercise through a decrease in recovery. On two separate occasions, absolute and relative peak oxygen uptake (VO2peak, peak ventilation (VEpeak, maximum heart rate (HRM, and time to exhaustion (TE obtained during the test were recorded. Subjective feedback provided by the participants was positive in that participants felt the test accurately simulated actions of a competitive sparring situation, and as a result athletes felt more motivated to perform well on this test. There was no significant between test difference in absolute VO2peak, relative VO2peak, HRM and TE (p > 0.05, indicating a potentially high reproducibility with the new test for these variables (test 1-test 2 difference of 0.04 L·min-1, 1 ml·kg-1·min-1, -3 beats·min-1, and 28 s; respectively. However, VEpeak displayed potentially less reproducibility due to a significant difference observed between tests (test 1- test 2 difference of -2.8 L·min-1, p < 0.05. There was a significant relationship between TE and relative VO2peak (R2 = 0.77, p < 0.001. Further developments to the test will need to address issues with work rate/force output assessment/monitoring. The new test accurately simulates the actions of competitive Karate sparring

    Full Text Available A multimodal dataset is presented, which has been collected for analyzing and measuring the quality of movement performed during sport activities. Martial arts (namely karate are taken as test-beds for investigation. Karate encompasses predefined sequences of movements (“katas” that can be carried out with different qualities, e.g., by performers at different skill levels (highly vs. poorly skilled.The experimental setup and method are described. The dataset is composed of motion capture (MoCap data, synchronized with video and audio recordings, of several participants with different levels of experience. The raw MoCap data are independent of any particular post-processing algorithm and can be used for other research purposes. In the second part of the paper, a set of measures is proposed to evaluate a kata performance. They are based on the geometrical and kinematic features, such as posture correctness and synchronization between limbs. and were chosen according to karate experts’ opinion.

    To determine the acute injury profile in each of six sports and compare the injury rates between the sports. Analysis of national sports injury insurance registry data. Finland during 1987-91. 621,691 person years of exposure among participants in soccer, ice hockey, volleyball, basketball, judo, or karate. Acute sports injuries requiring medical treatment and reported to the insurance company on structured forms by the patients and their doctors. 54,186 sports injuries were recorded. Injury rates were low in athletes aged under 15, while 20-24 year olds had the highest rates. Differences in injury rates between the sports were minor in this adult age group. Overall injury rates were higher in sports entailing more frequent and powerful body contact. Each sport had a specific injury profile. Fractures and dental injuries were most common in ice hockey and karate and least frequent in volleyball. Knee injuries were the most common cause of permanent disability. Based on the defined injury profiles in the different sports it is recommended that sports specific preventive measures should be employed to decrease the number of violent contacts between athletes, including improved game rules supported by careful refereeing. To prevent dental injuries the wearing of mouth guards should be encouraged, especially in ice hockey, karate, and basketball.

    Full Text Available O karate é uma técnica de combate sem armas que, sustentada por uma antiga tradição, tem como seu principal objetivo a formação do caráter do praticante. A compreensão da visão de mundo na qual o karate nasceu e se desenvolveu é debitária de uma dinâmica espiritual e psicológica singular cujo conhecimento é imprescindível para apreendê-la. O objetivo desta pesquisa é analisar o karate por meio de sua espiritualidade, já que, junto aos textos fundamentais de sua tradição recente, ela é tida como a essência presente em todas as dimensões da expressão da arte. Para tanto, vale-se de uma metodologia historiográfica de perspectiva fenomenológica. Karate-do veicula a espiritualidade do esvaziamento como norte de sua filosofia corporal. Temas com linhas fronteiriças tênues entre si são analisados pela perspectiva de tal espiritualidade. A abrangência desta dinâmica corresponde a um combate subtrativo visando uma apreensão fluida e intutitiva da realidade.Karate is a fight practice that does not make use of weapons. It is based on old traditions and its main aim is to develop a sense of personality in the practitioner. Karate originated from unique spiritual and psychological dynamics, which are of utmost importance for the full understanding of this practice. The objective of this research is to analyze karate-do by means of its spirituality. This is because, together with the fundamental texts about the recent tradition of this fight, spirituality is considered to be the essence present in all dimensions of the artistic expression of karate. To this end, the historiographical methodology of phenomenological perspective was employed in this study. Karate-do has the spirituality of the empty hands method as the north of its body philosophy. Themes with blurred borders are analyzed from this spiritual point of view herein.

    Full Text Available The present study investigated the influence of cognitive, motor, and Karate (accordingly the guidelines of the German-Karate-Federation, DKV training on the cognitive functioning and mental state of older people between 67 and 93 years of age. The three training groups consisted of 12 elderly participants; the waiting control group included 9 participants. Before the training, participants were evaluated with cognitive measurements (cognitive speed: number connection test, number symbol test; memory performance: digit-span test, blocking-tapping test, figure test and a measurement of emotional well-being. After this pre-testing they participated the specific training in on average 16 one-hour training sessions. The cognitive training exercised inductive thinking ability, the motor training worked on easy stretching and mobilization techniques, and the Karate training taught tasks of self-defense, partner training and Katas. After 16 training sessions all tests were applied again. The results show no significant difference in cognitive improvement dependent on group between the three training conditions. However a significant improvement was found in the emotional mental state measurement for the Karate group compared to the waiting control group. This result suggests that the high involvement in Karate leads to a feeling of self-worth and that even in elderly people integration of new sports helps to improve quality of life.

  12. Algorithms for Implicit Hitting Set Problems

    Chandrasekaran, Karthekeyan; Moreno-Centeno, Erick; Vempala, Santosh

    2011-01-01

    A hitting set for a collection of sets is a set that has a non-empty intersection with each set in the collection; the hitting set problem is to find a hitting set of minimum cardinality. Motivated by instances of the hitting set problem where the number of sets to be hit is large, we introduce the notion of implicit hitting set problems. In an implicit hitting set problem the collection of sets to be hit is typically too large to list explicitly; instead, an oracle is provided which, given a set H, either determines that H is a hitting set or returns a set that H does not hit. We show a number of examples of classic implicit hitting set problems, and give a generic algorithm for solving such problems optimally. The main contribution of this paper is to show that this framework is valuable in developing approximation algorithms. We illustrate this methodology by presenting a simple on-line algorithm for the minimum feedback vertex set problem on random graphs. In particular our algorithm gives a feedback vert...

    Full Text Available The struggle to establish regional library systems in Canada was won slowly, province by province, beginning in the 1930s. This article traces the story of one of the colourful leaders of the library profession, who established a regional library system in Prince Edward Island and set the stage for regional libraries in Nova Scotia. Grounded in adult education and a passion for social justice, Nora Bateson championed a vision of libraries as agents of personal and community development. Her zeal, commitment and clashes with those in power speak of the qualities needed by activists today, and of the challenges faced by those who see libraries as centres of change.

    This investigation had two purposes: (a) to identify and describe the coping strategies used by national champion figure skaters and (b) to examine the relationship between coping strategies and particular stress sources. Participants were 17 of 20 (85%) Senior U.S. National Champion figure skaters who won titles between 1985 and 1990. All skaters were interviewed, and the interview transcripts were content analyzed. General coping dimensions reported by at least 40% of the skaters included (a) rational thinking and self-talk, (b) positive focus and orientation, (c) social support (e.g., receiving support from coach, talking with friends and family), (d) time management and prioritization, (e) precompetitive mental preparation and anxiety management (e.g., relaxation, visualization), (f) training hard and smart, (g) isolation and deflection (e.g., not letting things get to me, avoiding/screening media), and (h) ignoring the stressor(s). It was also found that the skaters implemented different coping strategies depending on the specific stressors encountered.

    1993-07-01

    To evaluate the efficacy of Seisan kata as an aerobic power training mode, four male (28.5 +/- 4.2 y) Chito-Ryu karate black belt practitioners did kata continuously for 10 min. In separate sessions the kata (formal, organized movement sequences) were done at rates of 1 (PACE) and 2 (FAST) kata "cycles" per minute. Heartrate (HR) and VO2 were monitored continuously during the sessions. VO2 during the PACE and FAST sessions averaged 73 +/- 3 and 94 +/- 2% of leg cycling VO2peak, respectively. The corresponding HRs were 93 +/- 6 and 101 +/- 3% of HRmax (leg cycle test). PACE and FAST post-exercise blood lactates were 12 +/- 4 and 22 +/- 6%, respectively, of the maximal leg cycle test values. These data indicate that karate kata can be used as an effective and specific means for training aerobic power in karate practitioners.

    2016-12-01

    Background: In literature, the competitive sport of modern karate is almost always characterised as a combat sport involving injuries caused by impact effects and physical contact with opponents. There is a lack of data regarding the outcome after karate injuries, specifically with a view to the contact-free Kata karate. Methods: Performing a random test using a questionnaire, we collected data concerning regular medical treatment, prior surgeries of the locomotor system, and medical care. This study included 300 athletes from 65 countries (average age: 24.1 years; 176 male, 124 female) participating in the Karate World Cup 2014. Seven participants competed in both disciplines, 87 only in the Kata discipline, and 206 only in Kumite (the discipline involving physical contact with opponents). The statistical analysis was performed using a two-sided Chi-square test and the Fisher's exact test. Results: Recurrent medical treatment was most commonly required for the knee region (Kata 28.7 %, Kumite 26.7 %). In Kata the shoulder region came second (22.9 %), in Kumite the ankle region (21.8 %), followed by hand and foot in both groups. Medical treatment of the elbow area was more frequent in the Kata Group (p = 0.033), while in Kumite athletes' hand (p = 0.002) and foot injuries (p = 0.007) prevailed. Prior surgeries of athletes of both disciplines most commonly concerned the knee, followed by the ankle region in the Kata group and by the hand and head region in the Kumite group. Statistically significant differences between the two disciplines were found in head injuries (p = 0.004), which commonly do not occur in the Kata discipline. During the World Cup, 56.0 % of the athletes had no individual medical care and 24.6 % received no sports-related medical care in their home countries. Conclusion: Although the risk of injuries in Kumite Karate has been reduced by the introduction of gumshields, hand and foot protectors as well as a reform of

    Full Text Available The aims of this paper were to record injury rates among Iranian women competitive Shotokan karate athletes and propose possible predisposing factors. A prospective recording of the injuries resulting from all matches in 6 consecutive women national Shotokan Karate Championships in all age groups in Iran (season 2004-2005 was performed. Data recorded included demographic characteristics (Age and Weight, athletic background (rank, years of experience, time spent training and previous injuries, type, location and reason for the injury, and the result of the match. Results indicate 186 recorded injuries from a total of 1139 bouts involving 1019 athletes, therefore there were 0.163 injury per bout [C.I. 95%: 0.142-0.184] and 183 injuries per 1000 athletes [C.I. 95%: 159-205]. Injuries were most commonly located in the head and neck (55.4% followed by the lower limb (21%, upper limb (12.9% and trunk (10.8%. Punches (48. 4% were associated with more injuries than kicks (33.3%. The injuries consisted of muscle strain and contusion (81, 43.6%, hematoma and epistaxis (49, 26.3%, lacerations and abrasions (28, 15. 1%, concussion (13, 7%, tooth avulsion or subluxation (3, 1.6%, joint dislocation (3, 1.6% and fractures (3, 1.6%. In conclusion, as the majority of injuries are minor, and severe or longstanding injuries are uncommon, it can be argued that shotokan karate is a relatively safe for females, despite its image as a combat sport, where ostensibly the aim appears to injure your opponent. Further research is needed to evaluate the effective strategies to minimize the risk of injuries

    2015-08-01

    A major topic of current research in aging has been to investigate ways to promote healthy aging and neuroplasticity in order to counteract perceptual and cognitive declines. The aim of the present study was to investigate the benefits of intensive, sustained judo and karate martial arts training in young and older athletes and nonathletes of the same age for attenuating age-related dynamic visual acuity (DVA) decline. As a target, we used a moving stimulus similar to a Landolt ring that moved horizontally, vertically, or obliquely across the screen at three possible contrasts and three different speeds. The results indicated that (1) athletes had better DVA than nonathletes; (2) the older adult groups showed a larger oblique effect than the younger groups, regardless of whether or not they practiced a martial art; and (3) age modulated the results of sport under the high-speed condition: The DVA of young karate athletes was superior to that of nonathletes, while both judo and karate older athletes showed better DVA than did sedentary older adults. These findings suggest that in older adults, the practice of a martial art in general, rather than the practice of a particular type of martial art, is the crucial thing. We concluded that the sustained practice of a martial art such as judo or karate attenuates the decline of DVA, suggesting neuroplasticity in the aging human brain.

    Full Text Available The aim of the present study was to investigate the effect of a karate competition on the urinary excretion of proteins with high molecular weight and urinary creatinine to protein ratio in young male karate as. Ten young male karate as with the age range of 25±2.63 years, height of 175.7±5.15 cm and weight of 71.5±8.61 kg voluntarily took part in this study and participated in a karate competition. Before and 20 min after the competition, the urinary sample was collected and the levels of albumin, total protein, creatinine and urinary creatinine to protein ratio were measured and calculated. To investigate the changes of urinary proteins caused by competition, the student’s t-test for dependent groups was used. Glomerular proteinuria increased after the competition; however, it was only significant for albumin and creatinine (p = 0.009 and p = 0.018, respectively. Although total protein increased after the competition, it was not statistically significant (p = 0.184 and the creatinine to protein ratio did not make any significant changes (p = 0.532. Creatinine to protein ratio was less than 0.1 for the samples before and after the competition; therefore, proteinuria had a physiological range which was very far from nephritic and pathological proteinuria ranges; thus, it was not harmful.

    Nutrient intake of 29 male (M Group) and 16 female (F Group) highly competitive collegiate karate players were compared. The results were also compared with the daily energy expenditure (DEE), Japanese recommended dietary allowances (RDAs) or adequate dietary intakes (ADIs). Dietary information was collected using a 3-weekday diet record. Although the M Group showed significantly higher mean %RDAs or %ADIs in iron, vitamin B1, phosphorus, magnesium, and sodium than the F Group, many of the mean %RDAs or %ADIs were below RDAs or ADIs in both groups. The subjects who skipped meals tended to show lower mean %DEE, Japanese %RDAs or %ADIs in minerals and vitamins than the subjects who did not skip in both M and F Groups. The consumption of green and other vegetables and milk and dairy products in both M and F Groups were low. It is concluded that the male and female highly competitive karate players studied in the present study may be at risk of sub-optimal nutrient intake, which increases the potential for nutrient deficiency. The subjects were advised not to skip meals, and to consume a balanced high-carbohydrate, moderate-protein, low-fat diet with increasing green and other vegetables and milk and dairy products to increase mineral, vitamin and dietary fiber intakes.

    2008-06-01

    In order for evidence-based dentistry (EBD) to become part of decision making in practice, the most current and comprehensive research findings must be translated into practice. The use of Champions, influential individuals to support the transfer of knowledge among their peers, is one effective approach used by others in the health care field to successfully implement science research into clinical care. With the success of Champions in other health care areas, the American Dental Association (ADA) and the Journal of Evidence-Based Dental Practice, through an educational grant from Procter and Gamble, have launched a novel program to develop Evidence-Based Dentistry Champions. The EBD Champion program is developing a network of oral health care workers who will disseminate information about the application of an evidence-based approach to dental care and will serve as resources and mentors to their colleagues. The primary mechanism for developing the network of EBD Champions is through 3 annual EBD Champion Conferences, the first of which will be held at the ADA Headquarters in Chicago, IL, on May 2 and 3, 2008. The EBD Champion will serve as a resource to the practitioners in their communities, providing a grassroots approach to facilitating the implementation of an evidence-based approach to providing dental care.

  16. The role of the organizational champion in achieving health system change.

    2012-02-01

    In healthcare there is a long held wisdom that 'champions' are a key aspect of organizational change. Drawing on organizational management theory, we examine the role of champions in three health and social care organizations in England as they attempt to move services to a remote model of delivery, 'telecare'. The delivery of remote care is a significant policy in the U.K. and elsewhere, but its introduction has been challenging. Over three years ethnographic methods (observations, informed discussions and interviews) were used to analyze the role of organizational champions in implementing remote care. Cases were local authorities and associated primary care trusts. Participants were champions and organizational members involved in implementation. Our study shows that organizational champions are highly effective in the first phase of adoption, when change is contained within distinct sub-sets of practice. Moving beyond local contexts the effectiveness of the champions varied. Identification centered on the remote care work. This identification enabled the champions to motivate others and move beyond their normally prescribed roles, contributing to innovation ideas, processes and practices. When required to shift their work organization-wide, and share ideas outside their professional culture, some champions responded with resistance, resulting in a lack of innovation spread. These results caution against allowing change to become positioned within the remit of a few individuals. Whilst this strategy may be initially beneficial, the role of champion may be less useful, even detrimental to progress, in the later stages of implementation, particularly if identification with the new circumstances is not established.

    Athletes' kinanthropometric profiles are widely addressed in the scientific literature. Such profiles are particularly important in volleyball because absolute size contributes a significant percentage of total variance associated with athletic success. As in other team sports, volleyball players' kinanthropometric attributes correlate with the game's tactical demands. From 1992 through 2000, the Cuban women's volleyball team achieved top global performance, winning first place in three successive Summer Olympic Games. Describe the kinanthropometric profiles of Cuban women Olympic volleyball champions during 1992-2000 and compare these by position played. Measurements were taken of body composition, somatotype, proportionality and several anthropometric indicators in 41 Cuban women volleyball players, grouped by playing position. All were members of the national team that participated in the Summer Olympic Games in Barcelona (1992), Atlanta (1996) and Sydney (2000). Mean and standard deviations were calculated for all study variables. Analysis of variance was used to compare means for different positions for the variables weight; height; percent adipose, muscle and bone mass; body mass index; and muscle-to-bone ratio. Discriminant analysis was performed to identify anthropometric dimensions differentiating playing positions (center, spiker and setter), using pvolleyball players was balanced mesomorphic (2.7-3.6-2.9). Classified by position, centers (2.9-3.4-3.4) and spikers (2.8-3.6-2.9) presented an average mesomorphic-ectomorphic somatotype, and setters (2.6-3.7-2.6) were balanced mesomorphic. On assessing Somatotype Attitudinal Mean (SAM), centers and spikers showed more intrapositional homogeneity than that of setters. Centers were significantly taller (187.1±2.5 cm) than players in other positions. Centers' percent adipose tissue mass (28.9±2.7%) was significantly higher than that of setters (24.3±2.7%), who were leanest of all positions. The

    Full Text Available Purpose: The mechanisms involved in the coordination of muscle activity are not completely known: to investigate adaptive changes in human motor cortex Transcranial magnetic stimulation (TMS was often used. The sport models are frequently used to study how the training may affect the corticospinal system excitability: Karate represents a valuable sport model for this kind of investigations for its high levels of coordination required to athletes. This study was aimed at examining possible changes in the resting motor threshold (rMT and in the corticospinal response in karate athletes, and at determining whether athletes are characterized by a specific value of rMT.Methods: We recruited 25 right-handed young karate athletes and 25 matched non-athletes. TMS was applied to primary motor cortex (M1. Motor evoked potential (MEP were recorded by two electrodes placed above the first dorsal interosseous (FDI muscle. We considered MEP latencies and amplitudes at rMT, 110% of rMT, and 120% of rMT.Results: The two groups were similar for age (p > 0.05, height (p > 0.05 and body mass (p > 0.05. The TMS had a 70-mm figure-of-eight coil and a maximum output of 2.2 T, placed over the left motor cortex. During the stimulation, a mechanical arm kept the coil tangential to the scalp, with the handle at 45° respect to the midline. The SofTaxic navigator system (E.M.S. Italy, www.emsmedical.net was used in order to correctly identifying and repeating the stimulation for every subject. Compared to non-athletes, athletes showed a lower resting motor threshold (p < 0.001. Furthermore, athletes had a lower MEP latency (p < 0.001 and a higher MEP amplitude (p < 0.001 compared to non-athletes. Moreover, a ROC curve for rMT was found significant (area: 0.907; sensitivity 84%, specificity 76%.Conclusions: As the main finding, the present study showed significant differences in cortical excitability between athletes and non-athletes. The training can improve cortical

    Full Text Available Abstract The cross is a key skill in Male Artistic Gymnastics rings routines. However, few researches were found about this skill. There is knowledge about the forces needed to perform the cross, or about muscles activation, separately. The aim of this paper was to accomplish a comprehensive research about the biomechanics of cross on rings, in order to obtain a descriptive model about this skill. Therefore, the currently Olympic champion on rings event volunteered in this research. He performed three crosses with the usual apparatus in his training gym. The measurement methods were combined: One digital video camera, one strain gauge in each cable and surface electromyography of nine right shoulder muscles were used. Statistical analyses were performed by parametric and non parametric tests and descriptive statistics. Symmetry values were calculated for shoulder angles and cables of right and left side. Coefficient of variation of muscle activation and co contraction were verified. Within gymnast variability was calculated using biological coefficient of variation (BCV, discretely for kinematic measures. Low variability values of shoulder angles and cable forces were verified and low values of asymmetry as well. Muscle activation varied according to muscle function, while co-contraction values were different among trials. These results pointed out the characteristics of the cross performed by an elite gymnast. Knowledge about the characteristics of cross can inform coaches, practitioners and clinicians how a successful skill should be presented.

  20. Sustainable urban water management: understanding and fostering champions of change.

    2009-01-01

    This paper highlights and discusses ten characteristic attributes of emergent leaders (also known as 'champions') who worked as influential change agents within publicly managed, Australian water agencies to encourage more sustainable forms of urban water management. These attributes relate to: the 'openness to experience' personality characteristic; career mobility and work history demographics; personal and position power; strategic social networks; the culture of their organisations; and five distinguishing leadership behaviours (e.g. persisting under adversity). Guided by the findings of an international literature review, the author conducted a multiple case study involving six water agencies. This research identified attributes of these leaders that were typically strong and/or distinguishing compared to relevant control groups, as well as influential contextual factors. While it is widely acknowledged that these leaders play a critical role in the delivery of sustainable urban water management, there has been a paucity of context-sensitive research involving them. The research project highlighted in this paper is a response to this situation and has led to the development of a suite of 39 practical, evidence-based strategies to build leadership capacity throughout water agencies. Such capacity is one of the elements needed to drive the transition to more 'water sensitive cities'.

    In general, a hafiz who can memorize the Quran has many specialties especially in respect to their academic performances. In this study, the theory of multiple intelligences introduced by Howard Gardner is embedded in a developed psychometric instrument, namely Huffaz Intelligence Test (HIT). This paper presents the validation and the reliability of HIT of some tahfiz students in Malaysia Islamic schools. A pilot study was conducted involving 87 huffaz who were randomly selected to answer the items in HIT. The analysis method used includes Partial Least Square (PLS) on reliability, convergence and discriminant validation. The study has validated nine intelligences. The findings also indicated that the composite reliabilities for the nine types of intelligences are greater than 0.8. Thus, the HIT is a valid and reliable instrument to measure the multiple intelligences among huffaz.

    2017-08-03

    The 2016 revision of the World Health Organization (WHO) classification for lymphoma has included a new category of lymphoma, separate from diffuse large B-cell lymphoma, termed high-grade B-cell lymphoma with translocations involving myc and bcl-2 or bcl-6. These lymphomas, which occur in <10% of cases of diffuse large B-cell lymphoma, have been referred to as double-hit lymphomas (or triple-hit lymphomas if all 3 rearrangements are present). It is important to differentiate these lymphomas from the larger group of double-expressor lymphomas, which have increased expression of MYC and BCL-2 and/or BCL-6 by immunohistochemistry, by using variable cutoff percentages to define positivity. Patients with double-hit lymphomas have a poor prognosis when treated with standard chemoimmunotherapy and have increased risk of central nervous system involvement and progression. Double-hit lymphomas may arise as a consequence of the transformation of the underlying indolent lymphoma. There are no published prospective trials in double-hit lymphoma, however retrospective studies strongly suggest that aggressive induction regimens may confer a superior outcome. In this article, I review my approach to the evaluation and treatment of double-hit lymphoma, with an eye toward future clinical trials incorporating rational targeted agents into the therapeutic armamentarium. © 2017 by The American Society of Hematology.

    Full Text Available Learning motor skills is a complex task involving a lot of cognitive issues. One of the main issues consists in retrieving the relevant information from the learning environment. In a traditional learning situation, a teacher gives oral explanations and performs actions to provide the learner with visual examples. Using virtual reality (VR as a tool for learning motor tasks is promising. However, it raises questions about the type of information this kind of environments can offer. In this paper, we propose to analyze the impact of virtual humans on the perception of the learners. As a case study, we propose to apply this research problem to karate gestures. The results of this study show no significant difference on the after training performance of learners confronted to three different learning environments (traditional group, video and VR.

    Karat banana, pulque prepared from Agave species, and gac fruit are three traditional local food items recently studied intensively for their nutrition potential among traditional and indigenous peoples, and are examples of how local food-based strategies can be used to ensure micronutrient nutrition. Successful health promotion and intervention programs emphasizing traditional food systems are few in the international literature, but offer promise in understanding the potential of food-based strategies. Traditional food strategies could be used not only for alleviating malnutrition, but also for developing locally relevant programs for stemming the nutrition transition and preventing chronic disease, particularly among indigenous and traditional peoples who retain knowledge of using food species in their local ecosystems.

    The research was conducted with the aim of determining gender differentiations of some anthropological characteristics of male and female cadet karate players. To achieve this aim, a group of 10 morphological variables, ten motor tests, five situation motor test and six technical performance evaluation tests was applied. Two hundred and six competing players were measured, of which 105 male and 101 female. The examinees were divided according to weight categories (lower and higher weight categories). Based on the variance analysis and canon discrimination analysis a conclusion can be made: gender differentiations are most strongly expressed in morphological and basic motor area, and significantly less in the area of specific motor abilities and motor knowledge (technical efficiency).

    Objective Karate and judo are originally Japanese martial arts which may have different influences on adolescents’ behavior. This study was conducted to examine the total anger rate and its subscale-reactive anger, instrumental anger, and anger control-rates in young karateka and judoka. Methods A cross-sectional study was carried out in 11 to 19-year old boys. Adolescents included in the study were judoka (n=70), karateka (n=66), swimmers (n=59), and non athletes (n=96). One stage cluster sampling method was used to select judoka, karateka, and swimmers from sport clubs in Tehran. Students of governmental schools at the same area were chosen as the non-athletes group. The “Adolescent Anger Rating Scale” questionnaire was utilized to assess the anger rate. Findings The mean age of participants was 12.90(±2.06) years. The total anger rates were 45.40 (±5.61) in judoka, 41.53(±5.63) in karateka, 41.19(±5.33) in swimmers, and 45.44 (±8.58) in non athletes. In total anger scale karateka and swimmers had a significantly lower score compared to judoka and non athletes. In instrumental anger subscale the difference was significant just between karateka and non athletes. In reactive anger subscale judoka showed higher scores than swimmers. In anger control subscale the difference was significant between judoka and swimmers and also judoka and karateka. The difference of anger control between karateka and non athletes was significant. Conclusion The findings of this study propose a difference in the anger rate between judoka and karateka. In contrary to the results of previous studies, judo training may have no influence on anger control, while karate training could be beneficial. PMID:23056853

    Full Text Available Objectives: Secretory IgA is predominant immunoglobulin in secretions of the mucosal immune system. Low concentration of salivary IgA is associated with a higher risk of respiratory tract infections episodes in athletes during the training season. The purpose of this study was to determine whether orange-flavored whey based drink has beneficial effect on level of IgA in saliva after the training. Methods: Twenty healthy, young karate players participated in this study. They were divided into two groups. One group rinsed a mouth with 20 ml of liquid whey, two times in 30-min period: 15 and 30 min after training. Second group rinsed a mouth with 20 ml of whey based orange flavored soft drink, at the same time. Saliva was collected before the training, just after the training and after application of fluids. Results: We observed decrease in salivary flow after physical activity. The salivary flow was higher after the application of flavored drink compared to salivary flow after the application of whey. The absolute concentration of sIgA and sIgA secretion rate decreased just after exercise compared to pre exercise values. Application of whey elevated sIgA levels on day 1, while application of flavored drink caused increasing in sIgA levels on day 3. In all other cases sIgA level was decreasing even after applied stimuli. Conclusions: The exercise induces decreasing in salivary flow, sIgA absolute concentration and sIgA secretion rate. Application of fluid whey and flavored whey-based drink elevated salivary flow, but had little effect on absolute concentration of sIgA and sIgA secretion rate in young karate players.

    The aim of this study was to explore tapering practices among 10 Croatian open-class powerlifting champions (mean ± SD: age 29.2 ± 3.2 years; Wilks coefficient 355.1 ± 54.8). The athletes were interviewed about their tapering practices using a semi-structured interview, after which the audio content was transcribed. The athletes reported decreasing training volume during the taper by 50.5 ± 11.7% using a step type or an exponential type of taper with a fast decay. Training intensity was maintained or increased during the taper, and it reached its highest values 8 ± 3 days before the competition. Training frequency was reduced or maintained during the taper. The final week included a reduction in training frequency by 47.9 ± 17.5% with the last training session performed 3 ± 1 days before the competition. The participants typically stated that the main reasons for conducting the taper were maintaining strength and reducing the amount of fatigue. They also stated that (a) the taper was structured identically for the squat, bench press, and the deadlift; (b) the training during the taper was highly specific, the assistance exercises were removed, and the same equipment was used as during competition; (c) the source of information for tapering was their coach, and training fluctuated based on the coach's feedback; and (d) nutrition, foam rolling, static stretching, and massage were all given extra attention during the taper. These results may aid athletes and coaches in strength sports in terms of the optimization of tapering variables.

    One year of training data from 8 elite orienteers were divided into a transition phase (TP), general preparatory phase (GPP), specific preparatory phase (SPP), and competition phase (CP). Average weekly training volume and frequency, hours at different intensities (zones 1-3), cross-training, running, orienteering, interval training, continuous training, and competition were calculated. Training volume was higher in GPP than TP, SPP, and CP (14.9 vs 9.7, 11.5, and 10.6 h/wk, P < .05). Training frequency was higher in GPP than TP (10 vs 7.5 sessions/wk, P < .05). Zone 1 training was higher in GPP than TP, SPP, and CP (11.3 vs 7.1, 8.3, and 7.7 h/wk, P < .05). Zone 3 training was higher in SPP and CP than in TP and GPP (0.9 and 1.1 vs 1.6 and 1.5 h/ wk, P < .05). Cross-training was higher in GPP than SPP and CP (4.3 vs 0.8 h/wk, P < .05). Interval training was higher in GPP than TP, SPP, and CP (0.7 vs 0.3 h/wk, P < .05). High-intensity continuous training was higher in GPP than CP (0.9 vs 0.4 h/ wk, P < .05), while competition was higher in SPP and CP than in TP and GPP (1.3 and 1.5 vs 0.6 and 0.3 h/wk, P < .01). In conclusion, these champion endurance athletes achieved a progressive reduction in total training volume from GPP to CP via a shortening of each individual session while the number of training sessions remained unchanged. This decrease in training volume was primarily due to a reduction in the number of hours of low-intensity, non-sport-specific cross-training.

    We had the unique opportunity to study the skeletal muscle characteristics, at the single fiber level, of a world champion sprint runner who is the current indoor world record holder in the 60-m hurdles (7.30 s) and former world record holder in 110-m hurdles (12.91 s). Muscle biopsies were obtained from the vastus lateralis at rest and 4 h after a high-intensity exercise challenge (4 × 7 repetitions of resistance exercise). Single muscle fiber analyses were conducted for fiber type distribution (myosin heavy chain, MHC), fiber size, contractile function (strength, speed, and power) and mRNA expression (before and after the exercise bout). The world-class sprinter's leg muscle had a high abundance (24%) of the pure MHC IIx muscle fibers with a total fast-twitch fiber population of 71%. Power output of the MHC IIx fibers (35.1 ± 1.4 W/l) was 2-fold higher than MHC IIa fibers (17.1 ± 0.5 W/l) and 14-fold greater than MHC I fibers (2.5 ± 0.1 W/l). Additionally, the MHC IIx fibers were highly responsive to intense exercise at the transcriptional level for genes involved with muscle growth and remodeling (Fn14 and myostatin). To our knowledge, the abundance of pure MHC IIx muscle fibers is the highest observed in an elite sprinter. Further, the power output of the MHC IIa and MHC IIx muscle fibers was greater than any human values reported to date. These data provide a myocellular basis for the high level of sprinting success achieved by this individual.

    Interferometry and Thomson Scattering are implemented on the HIT-SI3 (Helicity Injected Torus - Steady Inductive 3) device to provide time resolved measurements of electron density and spatially resolved measurements of electron temperature, respectively. HIT-SI3 is a modification of the original HIT-SI apparatus that uses three injectors instead of two. The scientific aim of HIT-SI3 is to develop a deeper understanding of how injector behavior and interactions influence current drive and spheromak stability. The interferometer system makes use of an intermediate frequency between two parallel 184.3 μm Far-Infrared (FIR) laser cavities which are optically pumped by a CO2 laser. The phase shift in this beat frequency due to the plasma index of refraction is used to calculate the line-integrated electron density. To measure the electron temperature, Thomson Scattered light from a 20 J (1 GW pulse) Ruby laser off of free electrons in the HIT-SI3 plasma is measured simultaneously at four locations across the spheromak (nominally 23 cm minor radius). Polychromators bin the collected light into 3 spectral bands to detect the relative level of scattering. Work supported by the D.O.E.

    Full Text Available The presence of impurities in stainless steel can unexpectedly create a problem in welding. The difference of a small amount of impurities, from heat to heat, can induce the inconsistency in welding especially in automatic welding. This study is conducted to asses the influence of sulfur content of the steel on morphology of weld which is represented by the variation of weld pool and surface roughness of weld. The effect of sulfur on surface roughness of weld is studied in TIG welding of 316 stainless steels with different sulfur content. The influence of sulfur on the weld geometry, characterized by the ratio of depth and width of the weld (D/W, is studied in welding with various parameters. The variation of the weld geometry is conjointly studied in relation to the surface roughness of weldment. The effect of sulfur is also studied using a stationary arc with different current and duration. The variation of the diameter of a circular pool and the degree of protuberance which possibly emerged beneath the specimen is related to the sulfur content of the steel. The results of the study show the salient effect of sulfur on the surface roughness of weld. The surface roughness of steel with high sulfur content always more perturbed than that of steel with lower one; the different movement of liquid, characteristic of these two steels is posited to explain the difference. Greater degree of roughness is accompanied by a greater value of the ratio D/W. The results of the study with stationary arc show some points of a paramount importance. The effect of sulfur which hitherto considered advantageous to the formation of a weld with a higher ratio of D/W, turn out to be effective only in a specific range of welding parameters. In a different range, the weld geometry is more influenced by the arc characteristic, the anode spot.

    Price limit trading rules are adopted in some stock markets (especially emerging markets) trying to cool off traders' short-term trading mania on individual stocks and increase market efficiency. Under such a microstructure, stocks may hit their up-limits and down-limits from time to time. However, the behaviors of price limit hits are not well studied partially due to the fact that main stock markets such as the US markets and most European markets do not set price limits. Here, we perform detailed analyses of the high-frequency data of all A-share common stocks traded on the Shanghai Stock Exchange and the Shenzhen Stock Exchange from 2000 to 2011 to investigate the statistical properties of price limit hits and the dynamical evolution of several important financial variables before stock price hits its limits. We compare the properties of up-limit hits and down-limit hits. We also divide the whole period into three bullish periods and three bearish periods to unveil possible differences during bullish and bearish market states. To uncover the impacts of stock capitalization on price limit hits, we partition all stocks into six portfolios according to their capitalizations on different trading days. We find that the price limit trading rule has a cooling-off effect (object to the magnet effect), indicating that the rule takes effect in the Chinese stock markets. We find that price continuation is much more likely to occur than price reversal on the next trading day after a limit-hitting day, especially for down-limit hits, which has potential practical values for market practitioners.

  4. KARAT-LAMBDA - frequency dependent ray-traced troposphere delays for space applications

    Hobiger, Thomas; Baron, Philippe

    2014-05-01

    Space-geodetic microwave techniques work under the assumption that the only dispersive, i.e. frequency dependent delay contribution is caused by the ionosphere. In general, the refractivity, even for the troposphere, is a complex quantity which can be denoted as N = N0 + (N'(f) + i N''(f)) where N0 is a frequency independent term, and N'(f) and N''(f) represent the complex frequency dependence. Thereby, the imaginary part can be used to derive the loss of energy (absorption) and the real part can be assigned to the changes in the propagation velocity (refraction) and thus describes the delay of an electromagnetic wave which propagates through that medium. Although the frequency dependent delay contribution appears to be of small order, one has to consider that signals are propagating through few kilometers of troposphere at high elevations to hundredths of kilometers at low elevations. Therefore, the Kashima Ray-Tracing package (Hobiger et al., 2008) has been modified (and named KARAT-LAMBDA) to enable the consideration of a frequency dependent refractivity. By using this tool, it was studied if and to which extent future space geodetic instruments are affected from dispersive troposphere delays. Moreover, a semi-empirical correction model for the microwave link of the Atomic Clock Ensemble in Space (ACES) has been developed, based on ray-tracing calculations with KARAT-LAMBDA. The proposed model (Hobiger et al., 2013) has been tested with simulated ISS overflights at different potential ACES ground station sites and it could be demonstrated that this model is capable to remove biases and elevation dependent features caused by the dispersive troposphere delay difference between the up-link and down-link.

    2014-02-01

    This study aimed to investigate the kicking limb coordinative patterns adopted by karate practitioners (karateka) when impacting (IRK), or not impacting (NIRK) a target during a roundhouse kick. Six karateka performed three repetitions of both kicks while kicking limb kinematics were recorded using a stereophotogrammetric system. Intra-limb coordination was quantified for hip and knee flexion-extension from toe-off to kick completion, using the Continuous relative phase (CRP). Across the same time interval, thigh and shank angular momentum about the vertical axis of the body was calculated. For all trials, across all participants, CRP curve peaks and maximum and minimum angular momentum were determined. A RM-ANOVA was performed to test for differences between kicking conditions. The CRP analysis highlighted, during the central portion of both kicks, a delayed flexion of the hip with respect to the knee. Conversely, during the terminal portion of the CRP curves, the NIRK is performed with a more in-phase action, caused by a higher hip angular displacement. The NIRK is characterized by a lower angular momentum which may enhance control of the striking limb. It would seem that the issue of no impact appears to be solved through the control of all segments of the kicking limb, in contrast to the primary control of the lower leg only observed during the IRK.

    Price limit trading rules are useful to cool off traders short-term trading mania on individual stocks. The price dynamics approaching the limit boards are known as the magnet effect. However, the price dynamics after opening price limit hits are not well investigated. Here, we provide a detailed analysis on the price dynamics after the hits of up-limit or down-limit is open based on all A-share stocks traded in the Chinese stock markets. A "W" shape is found in the expected return, which reveals high probability of a continuous price limit hit on the following day. We also find that price dynamics after opening limit hits are dependent on the market trends. The time span of continuously hitting the price limit is found to an influence factor of the expected profit after the limit hit is open. Our analysis provides a better understanding of the price dynamics around the limit boards and contributes potential practical values for investors.

    Full Text Available We solve a long standing problem by showing that all known hypertopologies are hit-and-miss. Our solution is not merely of theoretical importance. This representation is useful in the study of comparison of the Hausdorff-Bourbaki or H-B uniform topologies and the Wijsman topologies among themselves and with others. Up to now some of these comparisons needed intricate manipulations. The H-B uniform topologies were the subject of intense activity in the 1960's in connection with the Isbell-Smith problem. We show that they are proximally locally finite topologies from which the solution to the above problem follows easily. It is known that the Wijsman topology on the hyperspace is the proximal ball (hit-and-miss topology in”nice” metric spaces including the normed linear spaces. With the introduction of a new far-miss topology we show that the Wijsman topology is hit-and-miss for all metric spaces. From this follows a natural generalization of the Wijsman topology to the hyperspace of any T1 space. Several existing results in the literature are easy consequences of our work.

    This paper examines the value of participatory approaches within interventions aimed at promoting mental health and wellbeing in the workplace. Specifically the paper explores data from the thematic evaluation of the Mental Health and Employment project strand within the Altogether Better programme being implemented in England in the Yorkshire and Humber region, which was funded through the BIG Lottery and aimed to empower people across the region to lead better lives. The evaluation combined a systematic evidence review with semi-structured interviews across mental health and employment projects. Drawing on both evaluation elements, the paper examines the potential of workplace-based 'business champions' to facilitate organizational culture change within enterprises within a deprived regional socio-economic environment. First, the paper identifies key policy drivers for interventions around mental health and employment, summarizes evidence review findings and describes the range of activities within three projects. The role of the 'business champion' emerged as crucial to these interventions and therefore, secondly, the paper examines how champions' potential to make a difference depends on the work settings and their existing roles, skills and motivation. In particular, champions can proactively coordinate project strands, embed the project, encourage participation, raise awareness, encourage changes to work procedures and strengthen networks and partnerships. The paper explores how these processes can facilitate changes in organizational culture. Challenges of implementation are identified, including achieving leverage with senior management, handover of ownership to fellow employees, assessing impact and sustainability. Finally, implications for policy and practice are discussed, and conclusions drawn concerning the roles of champions within different workplace environments. © The Author (2013).

    Background Worldwide, systemic arterial hypertension is a leading cause of death and non-communicable cardiovascular disease. A major factor contributing to this disease is a sedentary lifestyle. However, physical exercise, such as martial arts, may be an option for blood pressure (BP) control. The magnitude of post-exercise hypotension is associated with a prolonged decrease in BP in normotensive and hypertensive individuals. Objectives The present study aimed to verify the effects of a Contact Karate (CK) session on BP responses during a post-exercise recovery period in young adults. Patients and Methods Thirty-two male CK athletes volunteered (28.2 ± 6.7 years; 77.0 ± 5.7 kg; and 176.0 ± 4.7 cm) and underwent one CK session (50 minutes) and a control session in which no exercise was performed and the individuals remain seated during the whole time. BP was measured during rest (before sessions), as well as on the 15th, 30th, 45th, and 60th minutes of the post-exercise recovery. Results The systolic (SBP), diastolic (DBP), and mean arterial pressure (MAP) were significantly lower at the post-exercise period compared to pre-exercise rest (P < 0.05), with the largest reductions being observed at the 60th minutes of recovery [SBP (rest: 125.9 ± 4.7 vs. 60th minutes of recovery: 111.7 ± 5.4 mmHg); DBP (rest: 78.8 ± .7 vs. 60th minutes of recovery: 69.8 ± 2.7 mmHg)] and at the same periods of post-exercise recovery of the control session. Conclusions A single CK session can promote a decrease in BP for at least 60 minutes after performing this type of exercise in young adults. PMID:27826399

Patients and Methods Thirty-two male CK athletes volunteered (28.2 ± 6.7 years; 77.0 ± 5.7 kg; and 176.0 ± 4.7 cm and underwent one CK session (50 minutes and a control session in which no exercise was performed and the individuals remain seated during the whole time. BP was measured during rest (before sessions, as well as on the 15th, 30th, 45th, and 60th minutes of the post-exercise recovery. Results The systolic (SBP, diastolic (DBP, and mean arterial pressure (MAP were significantly lower at the post-exercise period compared to pre-exercise rest (P < 0.05, with the largest reductions being observed at the 60th minutes of recovery [SBP (rest: 125.9 ± 4.7 vs. 60th minutes of recovery: 111.7 ± 5.4 mmHg; DBP (rest: 78.8 ± .7 vs. 60th minutes of recovery: 69.8 ± 2.7 mmHg] and at the same periods of post-exercise recovery of the control session. Conclusions A single CK session can promote a decrease in BP for at least 60 minutes after performing this type of exercise in young adults.

    Facial trauma in sports has been associated with temporomandibular disorders. Because of the intensity and duration of training needed for elite-level competitions, high-performance athletes can have two to five times more traumatic injuries than recreational athletes. This study aimed to investigate the prevalence of temporomandibular disorders in high-performance martial arts fighters and compare it with the prevalence in recreational athletes and non-athletes. The Research Diagnostic Criteria for Temporomandibular Disorders was used to diagnose and classify professional karate-do practitioners (group I; n = 24), amateur karate-do practitioners (group II; n = 17), high-performance mixed martial arts fighters (group III; n = 13), and non-athletes (n = 28). The groups were compared with the chi-square test and tested for the difference between two proportions using a significance level of 5% (P 0.05). A diagnosis of arthralgia from disk displacement was made more frequently in groups I (45.8%; P = 0.013) and III (38.5%; P = 0.012) than in group IV (7.1%). The chronic pain associated with TMD was low intensity and low disability. While there was a high prevalence of temporomandibular disorders in the professional athletes in our study, the prevalence of the condition in recreational athletes was similar to that in individuals who did not practice martial arts. © 2015 John Wiley & Sons A/S.

  3. Hitting times for random walks with restarts

    CERN Document Server

    Janson, Svante

    2010-01-01

    The time it takes a random walker in a lattice to reach the origin from another vertex $x$, has infinite mean. If the walker can restart the walk at $x$ at will, then the minimum expected hitting time $T(x,0)$ (minimized over restarting strategies) is finite; it was called the ``grade'' of $x$ by Dumitriu, Tetali and Winkler. They showed that, in a more general setting, the grade (a variant of the ``Gittins index'') plays a crucial role in control problems involving several Markov chains. Here we establish several conjectures of Dumitriu et al on the asymptotics of the grade in Euclidean lattices. In particular, we show that in the planar square lattice, $T(x,0)$ is asymptotic to $2|x|^2\\log|x|$ as $|x| \\to \\infty$. The proof hinges on the local variance of the potential kernel $h$ being almost constant on the level sets of $h$. We also show how the same method yields precise second order asymptotics for hitting times of a random walk (without restarts) in a lattice disk.

    On January 12, 1975, a rock seemed to fall from the sky over New York State’s Schoharie County hitting the tractor of a local farmer, who was “preparing his fields for spring planting.” As the farmer later described the event to a reporter from the UFO INVESTIGATOR, the object glanced off the tractor, fell to the ground, and melted its way through a patch of ice that was two and one half inches thick. The farmer, Leonard Tillapaugh, called the county sheriff, Harvey Stoddard, who recovered the rock, noting that it “was still warm.” Why and how a sample of the rock came to Los Alamos is not known. However, it captivated a wide Laboratory audience, was subjected to rigorous testing and evaluation. Los Alamos used the scientific method in the manner promoted by Hynek. Did Los Alamos solve the mystery of the rock’s origin? Not definitively. Although the exact origin could not be determined, it was shown conclusively that the rock was not from outer space. With that said, the saga of Rock that hit New York came to an end. Nothing more was said or written about it. The principals involved have long since passed from the scene. The NICAP ceased operations in 1980. And, the rock, itself, has disappeared.

  5. Cutaneous presentation of Double Hit Lymphoma

    2016-04-01

    Full Text Available Diffuse large B-cell lymphoma (DLBCL is the most common type of non-Hodgkin lymphoma (NHL, representing approximately 25% of diagnosed NHL. DLBCL is heterogeneous disease both clinically and genetically. The 3 most common chromosomal translocations in DLBCL involve the oncogenes BCL2, BCL6, and MYC. Double hit (DH DLBCL is an aggressive form in which MYC rearrangement is associated with either BCL2 or BCL6 rearrangement. Patients typically present with a rapidly growing mass, often with B symptoms. Extranodal disease is often present. Though there is a paucity of prospective trials in this subtype, double hit lymphoma (DHL has been linked to very poor outcomes when patients are treated with standard R-CHOP. There is, therefore, a lack of consensus regarding the standard treatment for DHL. Several retrospective analyses have been conducted to help guide treatment of this disease. These suggest that DA EPOCH-R may be the most promising regimen and that achievement of complete resolution predicts better long-term outcomes.

    Full Text Available Evaluation champions in four state Extension systems described needs for training and support and perspectives on building evaluation capacity in their organization as part of a larger interview study exploring their roles, growth, and motivations. These 40 evaluation leaders identified needs for basic and advanced evaluation skills training, technical assistance, and practical learning via mentoring and project teams. Recommendations for organizational change in evaluation capacity included “top-down” investments in communication, training, and practical support, as well as increased “bottom-up” efforts by champions like themselves to advocate, model best practice, and contribute to training and mentoring peers. Implications for professional development and evaluation capacity building in Extension and other community-based organizations are discussed.

    2016-05-01

    Peer health champions have been suggested as an important component of multilevel workplace interventions to promote healthy behaviours such as physical activity (PA). There is accumulating quantitative evidence of their effectiveness but as yet little exploration of why and how champions influence peer behaviour. The current study explores the role of peer physical activity champions (PPACs) in influencing colleagues' PA behaviour from the perspectives of both champions and colleagues. Seven months after the introduction of a workplace PA programme in 17 small- and medium-sized enterprises (SMEs), two focus groups were held with PPACs and four with programme participants. Data were analysed using inductive thematic analysis. Three overarching themes were developed: how PPACs encourage PA, valuable PPAC characteristics and sustaining motivation for the PPAC role. Both direct encouragement from PPACs and facilitation of wider PA supportive social networks within the workplace encouraged behaviour change. PA behaviour change is a delicate subject and it was important that PPACs provided enthusiastic and persistent encouragement without seeming judgemental. Being a PA role model was also a valuable characteristic. The PPACs found it satisfying to see positive changes in their colleagues who had become more active. However, colleagues often did not engage in suggested activities and PPACs required resilience to maintain personal motivation for the role despite this. Incorporating PPACs into SME-based PA interventions is acceptable to employees. It is recommended that PPAC training includes suggestions for facilitating social connections between colleagues. Sensitivity is required when initiating and engaging in conversations with colleagues about increasing their PA. Programmes should ensure PPACs themselves are provided with social support, especially from others in the same role, to help sustain motivation for their role. These findings will be useful to health

    2017-06-21

    Double hit lymphomas (DHLs) are a new category in the World Health Organization newest classification for lymphoid malignancies. DHL encompasses various histologies of lymphomas where the MYC oncogene and either BCL2 or BCL6 oncogenes are present concomitantly. Several observational studies and retrospective series have demonstrated that patients with DHL carry a poor prognosis and respond less and for a shorter duration to standard R-CHOP (rituximab, cyclophosphamide, vincristine, adriamycin, and prednisone). These studies have also proposed that dose intensification (with Burkitt-like regimens such as DA-EPOCH-R [dose-adjusted rituximab, etoposide, vincristine, Adriamycin, cyclophosphamide, and prednisone]) might offer patients with DHL better outcomes and improved prognosis. In this timely review, we discuss incidence of DHL, testing implications of MYC translocation, current treatment strategies, and future directions. Understanding this entity and its therapeutic consequences is essential to improve patients' outcomes. Copyright © 2017 Elsevier Inc. All rights reserved.

    Double-hit lymphomas (DHLs) characterize a unique subset of B-cell non-Hodgkin lymphomas. DHL typically presents in older adults with high-risk clinical features. This entity carries a significantly inferior prognosis compared with typical cases of diffuse large B-cell lymphoma; however, emerging literature can identify discrete clinical features within DHL that are associated with a favorable prognosis. Emerging literature is also demonstrating that intensive upfront treatment strategies may improve outcome. Diagnosis, prognostication, and management of DHL are reviewed, as well as potential future directions incorporating novel biologically targeted therapies. Finally, double-expressing lymphomas (DELs) will be discussed and contrasted with DHL. Copyright © 2016 Elsevier Inc. All rights reserved.

  14. One-hit wonders of genomic instability

    Directory of Open Access Journals (Sweden)

    Strunnikov Alexander V

    2010-05-01

    Full Text Available Abstract Recent data show that cells from many cancers exhibit massive chromosome instability. The traditional view is that the gradual accumulation of mutations in genes involved in transcriptional regulation and cell cycle controls results in tumor development. This, however, does not exclude the possibility that some mutations could be more potent than others in destabilizing the genome by targeting both chromosomal integrity and corresponding checkpoint mechanisms simultaneously. Three such examples of "single-hit" lesions potentially leading to heritable genome destabilization are discussed. They include: failure to release sister chromatid cohesion due to the incomplete proteolytic cleavage of cohesin; massive merotelic kinetochore misattachments upon condensin depletion; and chromosome under-replication. In all three cases, cells fail to detect potential chromosomal bridges before anaphase entry, indicating that there is a basic cell cycle requirement to maintain a degree of sister chromatid bridging that is not recognizable as chromosomal damage.

  16. A Two-Hit Model of Autism: Adolescence as the Second Hit

    Picci, Giorgia; Scherf, K. Suzanne

    2015-01-01

    Adolescence brings dramatic changes in behavior and neural organization. Unfortunately, for some 30% of individuals with autism, there is marked decline in adaptive functioning during adolescence. We propose a two-hit model of autism. First, early perturbations in neural development function as a “first hit” that sets up a neural system that is “built to fail” in the face of a second hit. Second, the confluence of pubertal hormones, neural reorganization, and increasing social demands during adolescence provides the “second hit” that interferes with the ability to transition into adult social roles and levels of adaptive functioning. In support of this model, we review evidence about adolescent-specific neural and behavioral development in autism. We conclude with predictions and recommendations for empirical investigation about several domains in which developmental trajectories for individuals with autism may be uniquely deterred in adolescence.

    The potential cognitive and psychosocial effects of childhood epilepsy have significant implications for a child's self-image and academic achievement. This study focuses on a 10-week karate program for children and adolescents with epilepsy aimed at increasing social confidence, self-concept, and quality of life, as well as reducing parental anxiety. Eleven children (8-16 years old) and their parents participated in this questionnaire study, and complete data were available for nine of these families. Measures consisted of the Piers-Harris Children's Self-Concept Scale, the Quality of Life in Childhood Epilepsy (QOLCE) questionnaire, and the Parental Stress Index. By parental report, significant improvement in memory function and largely positive trends in quality of life on multiple subscales were observed. By child report, intellectual self-esteem and social confidence also improved. Parental stress decreased, although not significantly, suggesting a potential benefit and indicating a role for future interventions targeting family anxiety.

    The diagnosis of heparin-induced thrombocytopenia (HIT) can be challenging. The HIT Expert Probability (HEP) Score has recently been proposed to aid in the diagnosis of HIT. We sought to externally and prospectively validate the HEP score. We prospectively assessed pre-test probability of HIT for 51 consecutive patients referred to our Consultative Service for evaluation of possible HIT between August 1, 2012 and February 1, 2013. Two Vascular Medicine fellows independently applied the 4T and HEP scores for each patient. Two independent HIT expert adjudicators rendered a diagnosis of HIT likely or unlikely. The median (interquartile range) of 4T and HEP scores were 4.5 (3.0, 6.0) and 5 (3.0, 8.5), respectively. There were no significant differences between area under receiver-operating characteristic curves of 4T and HEP scores against the gold standard, confirmed HIT [defined as positive serotonin release assay and positive anti-PF4/heparin ELISA] (0.74 vs 0.73, p = 0.97). HEP score ≥ 2 was 100 % sensitive and 16 % specific for determining the presence of confirmed HIT while a 4T score > 3 was 93 % sensitive and 35 % specific. In conclusion, the HEP and 4T scores are excellent screening pre-test probability models for HIT, however, in this prospective validation study, test characteristics for the diagnosis of HIT based on confirmatory laboratory testing and expert opinion are similar. Given the complexity of the HEP scoring model compared to that of the 4T score, further validation of the HEP score is warranted prior to widespread clinical acceptance.

    The aim of the study was to examine the anthropometric features and body composition of athletes practising karate at a high and medium competitive level. Our study was carried out on a sample of 35 subjects practising karate and aged from 16.0 to 32.5 years. This sample was divided into two groups: group 1 ( n=14 elite athletes) and group 2 ( n=21 amateur athletes). Various anthropometric measurements were taken (weight, height both standing and sitting, diameters, circumferences and skinfold thickness) from which different anthropometric indices were calculated (body mass index, Scelic and Grant indices, arm muscle circumference and area), and the somatotype was then determined. The body composition of each subject was assessed using the skinfold technique and the Jackson-Pollock (J-P) and Sloan-Weir (S-W) equations. The two groups of athletes showed very similar measurements regarding anthropometric characteristics. Only the Scelix index presented a significantly different value in the two groups (49.6+/-1.3 for group 1 vs. 51.1+/-1.3 for group 2; psomatotype, while the amateur athletes presented a balanced mesomorphic type. Moreover, a lower percentage of fat mass was more frequent in the first group (J-P=8.1+/-2.4%; S-W=8.9+/-3.3%) than in the second one (J-P=9.8+/-1.6%; S-W=11.2+/-3.7%), although the differences between the two groups were not significant. We conclude that group 1 is characterized by a slightly prominent vertical development of the skeletal frame. This could be an anthropometric characteristic that is best suited to meet the specific functional requirements of this sport. Moreover, both groups of athletes are characterized by a low percentage of fat mass, particularly the elite group.

    On 25 July 2014, about a year after construction work began, the Experimental Area 2 (EAR2) of CERN’s neutron facility n_TOF recorded its first beam. Unique in many aspects, EAR2 will start its rich programme of experimental physics this autumn.   The last part of the EAR2 beamline: the neutrons come from the underground target and reach the top of the beamline, where they hit the samples. Built about 20 metres above the neutron production target, EAR2 is in fact a bunker connected to the n_TOF underground facilities via a duct 80 cm in diameter, where the beamline is installed. The feet of the bunker support pillars are located on the concrete structure of the n_TOF tunnel and part of the structure lies above the old ISR building. A beam dump located on the roof of the building completes the structure. Neutrons are used by physicists to study neutron-induced reactions with applications in a number of fields, including nuclear waste transmutation, nuclear technology, nuclear astrop...

    As part of the 20th Anniversary of the Public Understanding of Science journal, the journal has been reflecting on how the field and journal have developed. This research note takes a closer look at some of the trends, considering the journal's 50 most cited papers and using IRaMuTeQ, an open-source computer text analysis technique. The research note presents data that show that the move within public engagement from deficit to dialogue has been followed by a further shift from championing dialogue to criticising its practice. This shift has taken place alongside a continued, but changing, interest in media coverage, surveys and models of public understanding.

    The purpose of this study was first, to determine whether there were differences in the roundhouse kicking leg kinematics performed by highly skilled Muay Thai, Karate and Taekwondo practitioners (n = 8 per group). Next, analysis aimed to identify the kinematic determinants of effective roundhouse kicking performance. Three-dimensional (3D) lower limb kinematics were recorded using a nine camera infra-red motion capture system (500 Hz) during three maximal roundhouse kicks. Impact forces were recorded using a strain gauge (1000 Hz) attached to a kicking pad positioned at the height of each participant's mastoid process. Results showed that linear foot velocity at impact was moderately correlated with relative impact force (r = 0.66, P = 0.001). Discipline specific analyses of the temporal data indicated that the Muay Thai group had a shorter execution time (1.02 ± 0.15 s) than Taekwondo (1.54 ± 0.52 s, P = 0.028). Analysis of lower limb kinematic data indicated that both Karate (-947 ± 94 deg/s, P = 0.010) and Taekwondo (-943 ± 106 deg/s, P = 0.011) practitioners had faster knee extension velocities than the Muay Thai group (-706 ± 200 deg/s). Conversely, the Muay Thai practitioners (1.24 ± 0.15 m/s) had greater vertical centre of mass movement than both Karate (0.78 ± 0.24 m/s, P = 0.001) and Taekwondo groups (0.93 ± 0.19 m/s, P = 0.02). Our findings show that several fundamental movement patterns were common to the roundhouse kicking techniques across the Muay Thai, Karate, and Taekwondo disciplines. Effective roundhouse kicking performance was characterized by rapid pelvic axial rotation, hip abduction, hip flexion and knee extension velocities, combined with rapid movements of the COM towards the target.

A system of 25 variables in total – 12 morphological, 12 basic motor (the system of predictor variables and 1 variable of situational moving structure (criterion variable, i.e. the karate punch with the lead arm (oi-tsuki – was applied on a sample of 82 karate trainees aged between 10 and 14. The results of regression analysis showed that a system of morphological and basic motor variables had a significant impact on punching with the lead arm (p<0.01. The stepwise method identified the largest individual value in the case of morphological variables of arm length, upper arm skinfold and body mass at the level of significance p<0.01, whereas basic motor variables (long jump from a standing start and half squat with weight also have a level of significance p<0.01. This shows that respondents with longer arms, less subcutaneous fat tissue on the upper arm, higher body mass and greater static and explosive strength of the lower extremities achieve better results. Determining predictor validity by regression analysis and the stepwise method is employed in order to diagnose, assess, monitor and evaluate the direct punch with the lead arm, so the next battery of measurement instruments can be constructed: arm length, upper arm skinfold, body mass, half squat with weight, long jump from a standing position.

Outrora praticado às escondidas, no século XX Gichin Funakoshi tornou-o público e o difundiu. Partiu de Funakoshi a denominação karate-do, "o caminho das mãos vazias", que dá um caráter doutrinário à arte que deveria servir, mais do que como mera forma de luta, ao desenvolvimento da personalidade. Procura-se fazer um resgate teórico das idéias psicopedagógicas e da espiritualidade próprias do karate sob a luz dos paradigmas culturais de maior influência no pensamento de Funakoshi. Observa-se claramente a influência e complementaridade entre confucionismo e zen-budismo além da herança prática do bushidô que permitem compreender o pensamento de Funakoshi acerca da espiritualidade e transmissão do conhecimento.

    The FPA (Family Planning Association)'s recent pilot campaign to encourage parents to talk to their children about sex has generated an excellent response rate. Funded by the Department of Health as part of "The health of the nation" efforts to reduce unplanned teenage pregnancies, the campaign centered on two radio advertisements. Aired during March in Greater London and North West England, the advertisements featured a free phone number from which people could obtain free copies of the booklet "Answering your child's questions," part of the FPA's "Growing Up" series. Nearly 7500 copies of the booklet were distributed in response to over 5000 requests--2500 rang in the first week alone. Most requests were from parents (69% mothers, 31% fathers) with one to three children aged between 7 and 13. Over 1000 requests were from parents with children under 7. Hundreds of schools, youth clubs, health professionals and voluntary organizations requested multiple booklets for use in their work. Research carried out to gauge public reaction showed overwhelming support for the campaign's message, demonstrating the immense need by parents for information in this area. "Answering your child's questions" was praised for being "open, direct and easy to follow." One parent said, "The booklet arms parents with the right way of putting information across." Parents described the advertisements as "hard-hitting" and "attention-grabbing." One listener commented: "They really stopped me in my tracks." FPA director Doreen Massey said: "The favorable reaction to the campaign is extremely encouraging. We are looking at ways to relay this pilot effort into a full-scale UK-wide campaign next year."

  12. Implicit Hitting Set Problems and Multi-genome Alignment

    Science.gov (United States)

    Karp, Richard M.

    Let U be a finite set and S a family of subsets of U. Define a hitting set as a subset of U that intersects every element of S. The optimal hitting set problem is: given a positive weight for each element of U, find a hitting set of minimum total weight. This problem is equivalent to the classic weighted set cover problem.We consider the optimal hitting set problem in the case where the set system S is not explicitly given, but there is an oracle that will supply members of S satisfying certain conditions; for example, we might ask the oracle for a minimum-cardinality set in S that is disjoint from a given set Q. The problems of finding a minimum feedback arc set or minimum feedback vertex set in a digraph are examples of implicit hitting set problems. Our interest is in the number of oracle queries required to find an optimal hitting set. After presenting some generic algorithms for this problem we focus on our computational experience with an implicit hitting set problem related to multi-genome alignment in genomics. This is joint work with Erick Moreno Centeno.

    In this article we present a novel method of hit time and hit position reconstruction in long scintillator detectors. We take advantage of the fact that for this kind of detectors amplitude and shape of registered signals depends strongly on the position where particle hit the detector. The reconstruction is based on determination of the degree of similarity between measured and averaged signals stored in a library for a set of well-defined positions along the scintillator. Preliminary results of validation of the introduced method with experimental data obtained by means of the double strip prototype of the J-PET detector are presented.

    2007-07-01

    This article offers an analysis of the present competitive and regulatory framework of the European electricity sector. Considering the complexity of this industry, the focus in this work is mainly on the problem of market concentration of incumbents in the sector as a result of the liberalisation process. The new trend toward the creation of ''national champions'' as well as recent mergers between gas suppliers and electricity producers raised serious concerns about abuses of market power and risks of future collusion. Taking account of investment in interconnection as well as other international and regional experiences, the internal market issue is investigated as the solution to the''risks'' from liberalisation.

    At the heart of recovery-oriented psychiatric mental health care are the dignity and respect of each person and the ways in which helping professionals convey a person's uniqueness, strengths, abilities, and needs. "Person-first language" is a form of linguistic expression relying on words that reflect awareness, a sense of dignity, and positive attitudes about people with disabilities. As such, person-first language places emphasis on the person first rather than the disability (e.g., "person with schizophrenia" rather than "a schizophrenic"). This article champions the use of person-first language as a foundation for recovery-oriented practice and enhanced collaborative treatment environments that foster respect, human dignity, and hope.

    The traditional role of librarians to secure and provide access to the archives of recorded knowledge is being rapidly challenged on three fronts: the increasing technical sophistication of library users, the wide availability of information management software, and economic pressures on the growth of library collections. While we may argue endlessly about turf'' and ownership'', the real challenge is to forge a new ethic of librarianship which defies the stereotype of the passive provider of information services, explores new models of partnership with users, and champions an interactive environment in which to create the library of the future. The Main Library at Lawrence Livermore National Laboratory is actively engaged in testing experimental models of the library of the future, centered on dynamic user-librarian interactions, versatile information technologies, and on forecasting creative partnerships with library users in different environments. These experiments are described, evaluated, and their implications for future development are explored. 39 refs.

  8. Neoliberal technocracy: explaining how and why the US Food and Drug Administration has championed pharmacogenomics.

    Science.gov (United States)

    Hogarth, Stuart

    2015-04-01

    By 2004 the FDA had emerged as a champion of pharmacogenomics as an exemplar for novel approaches to drug development. This was made clear in 2004 when the agency released a wide-ranging report which positioned pharmacogenomics at the heart of a broader regulatory reform agenda. The Critical Path initiative addressed declining productivity of drug development by suggesting that the problem was a mismatch between the rapid pace of discovery in post-genomic biomedicine and the antiquated development process for new drugs. Framing their work in this context, FDA officials reconceptualised their role in the innovation process, in what was the first programmatic statement of a shift from a strictly gate-keeping role to a more collaborative or facilitative role as enablers of innovation. This paper situates the FDA's emergence as a champion of pharmacogenomics in the broader politics of pharmaceutical regulation in the USA. In making a contribution to the pharmaceuticalisation literature this paper will draw on the work of John Abraham who has argued that one of the primary drivers of pharmaceuticalisation has been "deregulatory state policies" and on Williams and colleagues who have argued that the changing relationship between regulatory agencies and the pharmaceutical industry is an important dimension of pharmaceuticalisation. This paper links this to the promotion of pharmaceutical futures such as pharmacogenomics and explores how this shift is also closely related to the trend towards a risk management approach to pharmaceutical regulation. The role of Bush appointees in the development and promotion of the Critical Path agenda is also examined.

  9. The Evolution of Champion Cross-Country-Skier Training: From Lumberjacks to Professional Athletes.

    Science.gov (United States)

    Sandbakk, Øyvind

    2017-02-01

    Competitive cross-country (XC) skiing has traditions extending back to the mid-19th century and was included as a men's event in the first Winter Games in 1924. Since then, tremendous improvements in equipment, track preparation, and knowledge about training have prompted greater increases in XC-skiing speeds than in any other Olympic sport. In response, this commentary focuses on how the training of successful XC skiers has evolved, with interviews and training data from surviving Norwegian world and Olympic XC champions as primary sources. Before 1970, most male champion XC skiers were lumberjacks who ran or skied long distances to and from felling areas while working long days in the woods. In addition, they trained as much as possible, with increased intensity during the autumn, while less work but more ski-specific training and competitions were done during the winter. Until the 1970s, few XC skiers were women, whom coaches believed tolerated less training than men did. Today's XC skiers are less physically active, but the influence of both science and the systematic approaches of former athletes and coaches have gradually taught XC skiers to adopt smarter, more goal-oriented training practices. Although the very high VO2max of world-class XC skiers has remained the same since the 1960s, new events in modern XC skiing have additionally required superior upper-body power, high-speed techniques, and tactical flexibility. These elements also emerge in the training of today's best skiers; women's physiological capacities and training routines especially seem to have improved dramatically.

    2011-01-01

    In this article we investigate the hitting time of some given boundaries for Bessel processes. The main motivation is coming from mathematical finance when dealing with volatility models but the results can also be used in optimal control problems. The aim is here to construct a new and efficient algorithm in order to approach this hitting time. As an application we will consider the hitting time of a given level for the Cox-Ingersoll-Ross process. The main tools we use are on one side an adaptation of the method of images to this particular situation and on the other side the connection existing between Cox-Ingersoll-Ross processes and Bessel processes.

  13. Experience with Video Head Impulse Testing (vHIT

    Directory of Open Access Journals (Sweden)

    Carmen ÁLVAREZ-SANTACRUZ

    2017-03-01

    Full Text Available Introduction and objective: The diagnosis and study of vestibular pathology has been always guided by the medical history, exploration and caloric test. The caloric test has some limitations because it only allows the study of horizontal semicircular canal and it is also poorly tolerated by patients. Alternatively, the vHIT (Video Head Impulse Test, allows the analysis of all semicircular channels being quicker to perform and less obtrusive. The objective of the following study is to reflect our initial experience with the vHIT and compare it with another diagnosis tests. Method: This is a observational, prospective and descriptive study, of one year of observation in our Healthcare center for all patients who described symptoms of dizziness, unsteadiness or vertigo. Results: A total of 155 patients were included. There was a clear predominance of females, being Meniere's disease the most frequently diagnosed entity. The diagnosis was reached by vHIT. Caloric test was also performed in patients without definite or doubt in the diagnosis. With the data, the statistical relationships were established, being significant between sex with vestibular neuritis and vestibular migraine. There was a statistically significant relationship between vestibule-ocular reflex and caloric test associated with the previous pathologies. Discussion: The head impulse assisted video is a quick, simple and well tolerated technique without adverse symptoms like the caloric test. The disparities of results are due to differences in the stimulated frequencies, being the vHIT more physiological. Conclusions: vHIT facilitates the complementary diagnosis of acute pathology, being a well-tolerated technique. However, in pathologies with central compensation the results by vHIT may be normal, requiring the caloric test for better diagnostic approach.

    2011-01-01

    We consider irreducible reversible discrete time Markov chains on a finite state space. Mixing times and hitting times are fundamental parameters of the chain. We relate them by showing that the mixing time of the lazy chain is equivalent to the maximum over initial states $x$ and large sets $A$ of the hitting time of $A$ starting from $x$. We also prove that the first time when averaging over two consecutive time steps is close to stationarity is equivalent to the mixing time of the lazy version of the chain.

    Baseball injuries from throwing and hitting generally occur as a consequence of the repetitive and high-energy motions inherent to the sport. Biomechanical studies have contributed to understanding the pathomechanics leading to injury and to the development of rehabilitation programs. Interval-based throwing and hitting programs are designed to return an athlete to competition through a gradual progression of sport-specific exercises. Proper warm-up and strict adherence to the program allows the athlete to return as quickly and safely as possible.

    Full Text Available Unfractionated heparin is a widely used drug to prevent deep vein thrombosis and pulmonary emboli in patients at risk. With the advent of newer anticoagulants having lesser side effects, its use has diminished but not out of service. Here, we report a case of deep venous thrombosis, in a patient on prophylactic dose of heparin, which was later found to be a manifestation of heparin-induced thrombocytopenia (HIT. Thrombosis in the presence of heparin prophylaxis should be considered as HIT rather than a failure of anticoagulation.

    Full Text Available New chemical entities are desperately needed that overcome the limitations of existing drugs for neglected diseases. Screening a diverse library of 10,000 drug-like compounds against 7 neglected disease pathogens resulted in an integrated dataset of 744 hits. We discuss the prioritization of these hits for each pathogen and the strong correlation observed between compounds active against more than two pathogens and mammalian cell toxicity. Our work suggests that the efficiency of early drug discovery for neglected diseases can be enhanced through a collaborative, multi-pathogen approach.

    The gamma-tracking technique optimises the determination of the energy and emission angle of gamma-rays detected by modern segmented HPGe detectors. This entails the determination, using the delivered pulse shapes, of the interaction points of the gamma-ray within the crystal. The direct method presented here allows the localisation of the hits using only a large sample of pulses detected in the actual operating conditions. No external crystal scanning system or pulse shape simulation code is needed. In order to validate this method, it is applied to sets of pulses obtained using the University of Liverpool scanning system. The hit locations are determined by the method with good precision.

    This study investigated the relationship between punching acceleration and selected strength and power variables in 19 professional karate athletes from the Brazilian National Team (9 men and 10 women; age, 23 ± 3 years; height, 1.71 ± 0.09 m; and body mass [BM], 67.34 ± 13.44 kg). Punching acceleration was assessed under 4 different conditions in a randomized order: (a) fixed distance aiming to attain maximum speed (FS), (b) fixed distance aiming to attain maximum impact (FI), (c) self-selected distance aiming to attain maximum speed, and (d) self-selected distance aiming to attain maximum impact. The selected strength and power variables were as follows: maximal dynamic strength in bench press and squat-machine, squat and countermovement jump height, mean propulsive power in bench throw and jump squat, and mean propulsive velocity in jump squat with 40% of BM. Upper- and lower-body power and maximal dynamic strength variables were positively correlated to punch acceleration in all conditions. Multiple regression analysis also revealed predictive variables: relative mean propulsive power in squat jump (W·kg-1), and maximal dynamic strength 1 repetition maximum in both bench press and squat-machine exercises. An impact-oriented instruction and a self-selected distance to start the movement seem to be crucial to reach the highest acceleration during punching execution. This investigation, while demonstrating strong correlations between punching acceleration and strength-power variables, also provides important information for coaches, especially for designing better training strategies to improve punching speed.

The decline in performance among national champion swimmers, both men and women and in short and long swims, is linear, at about 0.6% per year up to age 70–75, after which it accelerates in quadratic fashion. These conclusions are based primarily on cross-sectional studies, and little is known about individual performance declines with aging. Herein we present performance profiles of 19 male and 26 female national and international champion Masters swimmers, ages 25 to 96 years, participating in competitions for an average of 23 years. Methods and results: Swimmers’ longitudinal data were compared with the fastest times of world record holders across ages 35–100 years by two regression methods. Neither method proved to accurately model this data set: compared with the rates of decline estimated from the world record data, which represent the best recorded times at given ages, there was bias toward shallower rates of performance decline in the longitudinal data, likely owing to a practice effect in some swimmers as they began their Masters programs. In swimmers’ later years, once maximum performance had been achieved, individual profiles followed the decline represented in the world records, and a few swimmers became the world record holders.

On the other side, double-hit lymphomas with BCL2 and MYC translocation are characterized by advanced disease stage, extranodal and central nervous system involvements at presentation or disease progression. Case report. We reported a 73-year-old male patient with double-hit primary adrenal lymphoma and preserved adrenal function, showing a favorable clinical course. Computed tomography of abdomen showed a 9 7 cm mass of the left adrenal gland. Laparatomy with left adrenalectomy was done and histological examination revealed diagnosis of a diffuse large B-cell NHL (DLBCL, non-GCB subtype. The patient was treated with 6 cycles of R-CHOP chemotherapy with reduced doses of doxorubicin because of the decreased left verticle ejection fraction. The patient was followed up regularly for 20 months with no evidence of tumor recurrence despite the inherently poor prognostic profile and double-hit phenotype of the disease. Conclusion. R-CHOP chemotherapy in combination with adrenalectomy can be an effective first-line regimen for primary adrenal DLBCL, despite the inherently poor prognostic profile (non-GCB subtype, bulky disease, elevated lactate dehydrogenase and double-hit phenotype of the disease.

    A media competition was part of the Massachusetts Childhood Obesity Research Demonstration (MA-CORD) Study. Criss et al., previously outlined the development and implementation of the competition, including variation in reach and adoption of the intervention across schools and afterschool programs. In this qualitative study, we examine community, provider, and organizational factors that explain the variation of media competition reach in school and afterschool programs, and describe the awareness of the media competition across other community sectors. Durlak and DuPre's ecological framework for understanding effective implementation provided the theoretical underpinnings for this study. Fifty-four key informant interviews were conducted, transcribed, and analyzed. Organizational capacity of committed teachers/staff and adaptability of the media competition seemed to be drivers for higher reach within school and afterschool programs. Salient themes that emerged as facilitators of effective implementation were having a cascade of champions and providing opportunity to participate in the media competition outside traditional class time. Clinics and coalitions were identified as additional sectors aware of the media competition. Specifically, our findings offer a new perspective on intervention design and a recommended direction for further study.

    Businesses of all sizes and types use large amounts of energy and emit greenhouse gases and must therefore be included in community energy planning. As an environmentally sound alternative to standard grid electricity, green electricity is considered an important energy management option for organizations wishing to address climate change. Businesses that voluntarily purchase green electricity include multi-national corporations in the primary and secondary sectors, such as agriculture, mining and manufacturing. They consume large quantities of energy and therefore have large environmental footprints. Smaller tertiary and quaternary sector businesses such as retail, health care and education, consume less energy but are also voluntarily purchasing green electricity. This paper examined if the factors that influence the decision process to purchase green electricity differ between primary and secondary sector firms, and smaller tertiary and quaternary businesses. Two models were outlined describing factors that influence proactive environmental management initiatives in firms. A summary of the corporate health and safety and total quality management literature was used to question if institutional experience with those established structures should spillover and support energy management initiatives. The results of a cluster analysis suggested that primary and secondary firms, as well as smaller and less hierarchical tertiary and quaternary businesses, are strongly influenced by environmental champions to voluntarily purchase green electricity. 41 refs., 3 tabs., 2 figs.

    This preintervention/postintervention pilot study examined impact of onsite support by a dental hygiene champion (DHC) on oral health and quality of life (QOL) of elderly residents in three long-term care facilities (LTCFs) in Arkansas. Oral health and oral health-related QOL were operationalized using the Oral Health Assessment Tool (OHAT) and Geriatric Oral Health Assessment Index (GOHAI), respectively. CNAs in Facility A received standardized oral health education/materials with onsite DHC support. Facility B received education/materials only. Facility C served as control. Data analyses included Wilcoxon-signed rank tests (OHAT) and repeated measures ANOVA (GOHAI) (p ≤ .05). OHAT postintervention data in Facility A showed significant improvements in three measured areas (tongue health, denture status, and oral cleanliness); in Facility B, one area (tongue health); and none in Facility C. No significant differences were found in GOHAI scores across facilities. Findings suggest that the presence of DHCs in LTCFs may positively impact the oral health of CNA-assisted residents.

    Dementia in retired boxers, also referred to as "dementia pugilistica" (DP), is usually attributed to repeated concussive and subconcussive blows to the head. We report the case of a former world boxing champion whose progressive cognitive decline could be ascribed to DP, cerebral infarcts and Wernicke-Korsakoff syndrome. This case demonstrates that dementia in retired boxers may be caused and/or exacerbated by etiologic factors other than DP. We correlated the clinical features with the histochemical and immunohistochemical changes observed on autopsy brain material from a retired boxer, reviewed the literature on boxing-related dementia, and compared our findings with previous reports on DP. Neuropathologic examination revealed numerous neurofibrillary tangles (NFTs), rare neuritic plaques (NPs), multiple cerebral infarcts, fenestrated septum pellucidum, atrophic and gliotic mamillary bodies, and pale substantia nigra and locus ceruleus. Our neuropathologic data confirmed the notion that dementia in retired boxers could be due to several factors such as DP, multiple cerebral infarcts and Wernicke-Korsakoff syndrome. Our findings illustrate the need to comprehensively examine former boxers with dementia as well as carefully evaluate the neuropathologic changes that may cause or contribute to the patient's cognitive and behavioral symptoms. Such an approach is crucial in order to provide prompt and more definitive therapies.

    2007-03-01

    Full Text Available Abstract Background Despite the Government acting quickly to reassure parents about MMR safety following the publication of the 1998 paper by Wakefield and colleagues, MMR uptake declined. One of the reasons suggested for this decline is a loss of public trust in politicians and health professionals. The purpose of this analysis was to examine parents' views on the role the media, politicians and health professionals have played in providing credible evidence about MMR safety. Methods A qualitative focus group study conducted with parents living in Central Scotland. Eighteen focus groups were conducted with 72 parents (64 mothers and 8 fathers between November 2002 and March 2003. Purposive sampling was used to ensure maximum variation among parents. Results In the period after the MMR controversy, parents found it difficult to know who to trust to offer balanced and accurate information. The general consensus was that politicians were untrustworthy in matters of health. The motives of primary health care providers were suspected by some parents, who saw them as having a range of vested interests (including financial incentives. Among the sources of evidence seen by some parents as more credible were other parents, and Andrew Wakefield who was viewed as an important whistle-blower and champion of ordinary parents. Conclusion The provision of accurate information is only one aspect of helping parents make immunisation decisions. Establishing and maintaining trust in the information provided is also important. The MMR controversy may provide useful lessons for health professionals about trust and credibility that may be generalisable to future health controversies.

    Full Text Available The synergistic interaction between teammates in association football has properties that can be captured by Social Network Analysis (SNA. The analysis of networks formed by team players passing a ball in a match shows that team success is correlated with high network density and clustering coefficient, as well as with reduced network centralization. However, oversimplification needs to be avoided, as network metrics events associated with success should not be considered equally to those that are not. In the present study, we investigated whether network density, clustering coefficient and centralization can predict successful or unsuccessful team performance. We analyzed 12 games of the Group Stage of UEFA Champions League 2015/2016 Group C by using public records from TV broadcasts. Notational analyses were performed to categorize attacking sequences as successful or unsuccessful, and to collect data on the ball-passing networks. The network metrics were then computed. A hierarchical logistic-regression model was used to predict the successfulness of the offensive plays from network density, clustering coefficient and centralization, after controlling for the effect of total passes on successfulness of offensive plays. Results confirmed the independent effect of network metrics. Density, but not clustering coefficient or centralization, was a significant predictor of the successfulness of offensive plays. We found a negative relation between density and successfulness of offensive plays. However, reduced density was associated with a higher number of offensive plays, albeit mostly unsuccessful. Conversely, high density was associated with a lower number of successful offensive plays (SOPs, but also with overall fewer offensive plays and “ball possession losses” before the attacking team entered the finishing zone. Independent SNA of team performance is important to minimize the limitations of oversimplifying effective team synergies.

    We present a cognitive model, based on the mathematical theory of point processes, which extends the results of two studies by Johansen (Physica A 276 (2000) 338; Physica A 296 (2001) 539) on download relaxation dynamics. Responses from subjects are considered as single events, which are received from original listeners or readers and from a network of social contacts, through which a message may propagate further. We collected data on the number of daily visits at our web site after a radio interview with the second author, in which the name of the web site was mentioned. A model based on an exponential hit time distribution and a homogeneous point process for regular visitors fits our data and Johansen's very well and is superior to both the power law and the logarithmic function. The fits suggest that hit data from different sources share the same cognitive mechanism, which are controlled merely by the encoding and retrieval of the target information memorised.

    Stevinson, C. D.; Biddle, S. J.

    1998-01-01

    OBJECTIVES: To investigate whether runners' cognitions during a marathon are related to "hitting the wall". To test a new and more comprehensive system for classifying cognition of marathon runners. METHODS: Non-elite runners (n = 66) completed a questionnaire after finishing the 1996 London marathon. The runners were recruited through the charity SPARKS for whom they were raising money by running in the race. RESULTS: Most runners reported that during the race their thoughts were internally associative, with internally dissociative thoughts being the least prevalent. Runners who "hit the wall" used more internal dissociation than other runners, indicating that it is a hazardous strategy, probably because sensory feedback is blocked. However, internal association was related to an earlier onset of "the wall", suggesting that too much attention on physical symptoms may magnify them, thereby exaggerating any discomfort. External dissociation was related to a later onset, probably because it may provide a degree of distraction but keeps attention on the race. CONCLUSIONS: "Hitting the wall" for recreational non-elite marathon runners is associated with their thought patterns during the race. In particular, "the wall" is associated with internal dissociation.

  11. COPD: A stepwise or a hit hard approach?

    2016-01-01

    Current guidelines differ slightly on the recommendations for treatment of Chronic Obstructive Pulmonary Disease (COPD) patients, and although there are some undisputed recommendations, there is still debate regarding the management of COPD. One of the hindrances to deciding which therapeutic approach to choose is late diagnosis or misdiagnosis of COPD. After a proper diagnosis is achieved and severity assessed, the choice between a stepwise or "hit hard" approach has to be made. For GOLD A patients the stepwise approach is recommended, whilst for B, C and D patients this remains debatable. Moreover, in patients for whom inhaled corticosteroids (ICS) are recommended, a step-up or "hit hard" approach with triple therapy will depend on the patient's characteristics and, for patients who are being over-treated with ICS, ICS withdrawal should be performed, in order to optimize therapy and reduce excessive medications. This paper discusses and proposes stepwise, "hit hard", step-up and ICS withdrawal therapeutic approaches for COPD patients based on their GOLD group. We conclude that all approaches have benefits, and only a careful patient selection will determine which approach is better, and which patients will benefit the most from each approach.

    Full Text Available The J-PET detector being developed at the Jagiellonian University is a positron emission tomograph composed of the long strips of polymer scintillators. At the same time, it is a detector system that will be used for studies of the decays of positronium atoms. The shape of photomultiplier signals depends on the hit time and hit position of the gamma quantum. In order to take advantage of this fact, a dedicated sampling front-end electronics that enables to sample signals in voltage domain with the time precision of about 20 ps and novel reconstruction method based on the comparison of examined signal with the model signals stored in the library has been developed. As a measure of the similarity, we use the Mahalanobis distance. The achievable position and time resolution depend on the number and values of the threshold levels at which the signal is sampled. A reconstruction method as well as preliminary results are presented and discussed.

    Strecker, E, Foster, EB, and Pascoe, DD. Test-retest reliability for hitting accuracy tennis test. J Strength Cond Res 25(12): 3501-3505, 2011-The purpose of this investigation was to assess a test-retest reliability of the hitting accuracy tennis test (HATT). Twelve National Collegiate Athletic Association (NCAA) division I tennis players (4 men and 8 women) volunteered to participate in this investigation. Skill tests consisted of 15 consecutive ground strokes in all 4 directions (forehand [FH] and backhand [BH]; crosscourt and up the line) with not >1 minute between directions. The court was divided into 12 areas, and each area was assigned a value according to a grid system based on offensive, defensive, and neutral shots ranging from 1 point to 6 points. Total score, unforced errors, and shot index (total number of shots that landed on optimal performance areas 5 and 6 minus total number of unforced errors) were used for statistical analysis. The order of shot direction was randomized between participants and trials. The analysis of variance with repeated measures (p value ≤ 0.05) of this investigation showed no statistical difference between trials on any of the measurements. The results also suggest that division I level tennis players have the ability to hit accurately specific targets on a tennis court using either FH or BH with minimal daily variation. Therefore, we conclude that the HATT for trained tennis athletes is a simple, reliable, and accurate assessment tool to measure tennis skill performance based on accuracy. The HATT is also an easy, inexpensive training device that coaches can use to monitor players development.

    Full Text Available The Holistic Integrity Test (HIT - Quantified Resilience Analysis. Rising sea levels and wider climate change mean we face an increasing risk from flooding and other natural hazards. Tough economic times make it difficult to economically justify or afford the desired level of engineered risk reduction. Add to this significant uncertainty from a range of future predictions, constantly updated with new science. We therefore need to understand not just how to reduce the risk, but what could happen should above design standard events occur. In flood terms this includes not only the direct impacts (damage and loss of life, but the wider cascade impacts to infrastructure systems and the longer term impacts on the economy and society. However, understanding the “what if” is only the first part of the equation; a range of improvement measures to mitigate such effects need to be identified and implemented. These measures should consider reducing the risk, lessening the consequences, aiding the response, and speeding up the recovery. However, they need to be objectively assessed through quantitative analysis, which underpins them technically and economically. Without such analysis, it cannot be predicted how measures will perform if the extreme events occur. It is also vital to consider all possible hazards as measures for one hazard may hinder the response to another. The Holistic Integrity Test (HIT, uses quantitative system analysis and “HITs” the site, its infrastructure, contained dangers and wider regional system to determine how it copes with a range of severe shock events, Before, During and After the event, whilst also accounting for uncertainty (as illustrated in figure 1.

    This document describes the early stage of the reconstruction chain that was developed for the ArgoNeuT and MicroBooNE experiments at Fermilab. These experiments study accelerator neutrino interactions that occur in a Liquid Argon Time Projection Chamber. Reconstructing the properties of particles produced in these interactions requires knowledge of the micro-physics processes that affect the creation and transport of ionization electrons to the readout system. A wire signal deconvolution technique was developed to convert wire signals to a standard form for hit reconstruction, to remove artifacts in the electronics chain and to remove coherent noise.

    Drug-like and lead-like hits derived from HTS campaigns provide good starting points for lead optimization. However, too strong emphasis on potency as hit-selection parameter might hamper the success of such projects. A detailed absorption, distribution, metabolism, excretion and toxicology (ADME-Tox) profiling is needed to help identify hits with a minimum number of (known) liabilities. This is particularly true for drug-like hits. Herein, we describe how to break down large numbers of screening hits and we provide a comprehensive overview of the strengths and weaknesses for each structural class. The overall profile (e.g. ligand efficiency, selectivity and ADME-Tox) is the distinctive feature that will define the priority for follow-up.

    Science.gov (United States)

    Miyata, Shigeki; Maeda, Takuma

    2016-03-01

    Heparin-induced thrombocytopenia (HIT) is a prothrombotic side effect of heparin therapy caused by HIT antibodies, i.e., anti-platelet factor 4 (PF4)/heparin IgG with platelet-activating properties. For serological diagnosis, antigen immunoassays are commonly used worldwide. However, such assays do not indicate their platelet-activating properties, leading to low specificity for the HIT diagnosis. Therefore, over-diagnosis is currently the most serious problem associated with HIT. The detection of platelet-activating antibodies using a washed platelet activation assay is crucial for appropriate HIT diagnosis. Recent advances in our understanding of the pathogenesis of HIT include it having several clinical features atypical for an immune-mediated disease. Heparin-naïve patients can develop IgG antibodies as early as day 4, as in a secondary immune response. Evidence for an anamnestic response on heparin re-exposure is lacking. In addition, HIT antibodies are relatively short-lived, unlike those in a secondary immune response. These lines of evidence suggest that the mechanisms underlying HIT antibody formation may be compatible with a non-T cell-dependent immune reaction. These atypical clinical and serological features should be carefully considered while endeavoring to accurately diagnose HIT, which leads to appropriate therapies such as immediate administration of an alternative anticoagulant to prevent thromboembolic events and re-administration of heparin during surgery involving cardiopulmonary bypass when HIT antibodies are no longer detectable.

    Starting from a hit series from a GNF compound library collection and based on a cell-based proliferation assay of Plasmodium falciparum, a novel imidazolopiperazine scaffold was optimized. SAR for this series of compounds is discussed, focusing on optimization of cellular potency against wild-type and drug resistant parasites and improvement of physiochemical and pharmacokinetic properties. The lead compounds in this series showed good potencies in vitro and decent oral exposure levels in vivo. In a Plasmodium berghei mouse infection model, one lead compound lowered the parasitemia level by 99.4% after administration of 100 mg/kg single oral dose and prolonged mice survival by an average of 17.0 days. The lead compounds were also well-tolerated in the preliminary in vitro toxicity studies and represents an interesting lead for drug development.

  8. Determining a Class of Markov Chains by Hitting Time

    Institute of Scientific and Technical Information of China (English)

    @@1 Introduction In many practical problems we often cannot observe the behavior of all states for a Markov chain (see [3-5]). A natural question is that from the observable data of a part of states, can one still obtain all statistical characteristics of the Markov chains. In this paper we give the positive answer for this question and prove the surprising result that the transition rate matrix of the birth-death chains with reflecting barriers and Markov chains on a star graph can be uniquely determined by the probability density functions (pdfs) of the sojourn times and the hitting times at a single special state. This result also suggest a new special type of statistics for Markov chains.

  9. Quantization of Random Walks: Search Algorithms and Hitting Time

    Science.gov (United States)

    Santha, Miklos

    Many classical search problems can be cast in the following abstract framework: Given a finite set X and a subset M ⊆ X of marked elements, detect if M is empty or not, or find an element in M if there is any. When M is not empty, a naive approach to the finding problem is to repeatedly pick a uniformly random element of X until a marked element is sampled. A more sophisticated approach might use a Markov chain, that is a random walk on the state space X in order to generate the samples. In that case the resources spent for previous steps are often reused to generate the next sample. Random walks also model spatial search in physical regions where the possible moves are expressed by the edges of some specific graph. The hitting time of a Markov chain is the number of steps necessary to reach a marked element, starting from the stationary distribution of the chain.

    The high societal and individual cost of schizophrenia necessitates finding better, more effective treatment, diagnosis, and prevention strategies. One of the obstacles in this endeavor is the diverse set of etiologies that comprises schizophrenia. A substantial body of evidence has grown over the last few decades to suggest that schizophrenia is a heterogeneous syndrome with overlapping symptoms and etiologies. At the same time, an increasing number of clinical, epidemiological, and experimental studies have shown links between schizophrenia and inflammatory conditions. In this review, we analyze the literature on inflammation and schizophrenia, with a particular focus on comorbidity, biomarkers, and environmental insults. We then identify several mechanisms by which inflammation could influence the development of schizophrenia via the two-hit hypothesis. Lastly, we note the relevance of these findings to clinical applications in the diagnosis, prevention, and treatment of schizophrenia. Copyright © 2013 Elsevier Ltd. All rights reserved.

  12. Anxiety vulnerability in women: a two-hit hypothesis.

    Science.gov (United States)

    Catuzzi, Jennifer E; Beck, Kevin D

    2014-09-01

    Females are twice as likely to develop an anxiety disorder compared to males, and thus, are believed to possess an innate vulnerability that increases their susceptibility to develop an anxiety disorder. However, studies using aversive learning paradigms to model anxiety disorders in humans and animals have revealed contradictory results. While females exhibit the ability to rapidly acquire stimulus-response associations, which may result from a greater attentional bias towards threat, females are also capable to readily extinguish these associations. Thus, there is little evidence to suggest that the female sex represents a vulnerability factor of anxiety, per se. However, if females are to possess a second vulnerability factor that increases the inflexibility of stimulus-response associations, then an anxiety disorder may be more likely to develop. Behavioral inhibition (BI) is a vulnerability factor associated with the formation of inflexible stimulus-response associations. In this "two hit" model of anxiety vulnerability, females possessing a BI temperament will rapidly acquire stimulus-response associations that are resistant to extinction, resulting in the development of an anxiety disorder. In this review we explore evidence for a "two-hit" hypothesis underlying anxiety vulnerability in females. We explore the literature for evidence of a sex difference in attentional bias towards threat that may lead to the facilitated acquisition of stimulus-response associations in females. We also provide evidence that BI is associated with inflexible stimulus-response association formation. We conclude with data generated from our laboratory that highlights the additive effect of the female sex and behavioral inhibition vulnerabilities using a model behavior for anxiety disorder-susceptibility, active avoidance.

    Full Text Available A table tennis player should fixate at different distances; track the objects with different speed, and in different visual environment. Their visual skills must be well developed for these capabilities. Therefore, visual acuity in reduced lumination and facility of ocular accommodation those are two criteria for visual skills have been compared in table tennis players and normal non-players. Twenty-nine young table tennis champions and 29 normal matched non-players (did not take part in any racket sports game were evaluated. Basic visual and eye examinations were done for both of them. Normal results in basic examination were fundamental requirement for all the subjects. +/-2.00 sphere lenses for accommodation facility are used. An electrical current regulator changed the output light intensity of a conventional chart projector (Topcon. Light intensity decreased to 10 cd·m-2 and visual acuity tested. In comparison of visual acuity in reduced lumination and facility of ocular accommodation in table tennis champions and non-players there are significant differences (p < 0.001. In the preliminary visual tests there was not any significant different in the two groups but the results in the top level table tennis player was very uniform and in every test and the standard deviation was lesser in tennis player group than non-players. These results show that motor and sensorial functions of expert players are well developed. That is consistent with other researchers. This result was interpreted as reflecting a better perceptual system of experts to the constraints encountered during table tennis and its use in practical settings for evaluating athletes or detecting sport talents. However some visual and perceptual training that usually used in orthoptics can be used for novice table tennis player to improve their abilities

    To compare bone mineral density (BMD) gains in adolescents of both genders stratified according to different martial art styles in a 9-month follow-up study. The longitudinal study consisted of 29 adolescents of both genders and age between 11 and 17 years stratified into a control group (not engaged in any sport) and 50 fighters (kung fu/karate, n = 29; judo, n = 21). All 79 subjects underwent anthropometric measures (weight, height, leg length, and height set) and dual-energy X-ray absorptiometry (BMD, in g/cm(2)) at 2 moments, baseline and 9 months later. Maturity offset (age at peak height velocity), lean soft tissue, chronological age, and resistance training were treated as covariates. Male judoists presented higher gains in BMD-spine [0.098 g/cm(2) (95% confidence interval, 0.068-0.128)] than control group [0.040 g/cm(2) (95% confidence interval, 0.011-0.069)] (post hoc test with P  = .030). There was no effect of martial art on BMD gains among girls. Independently of gender, in all multivariate models, lean soft tissue constituted the most relevant covariate. Judo practice in adolescents affected the bone accrual significantly after 9-month follow-up compared with controls, mainly in boys.

    2011-08-01

    Small rural hospitals face considerable financial and personnel resource shortages which hinder their efforts to implement complex health information technology (HIT) systems. A survey on the use of HIT was completed by 85% of Iowa's 82 Critical Access Hospitals (CAH). Analyses indicate that low IT staffing in CAHs is a barrier to implementing HIT solutions. CAHs with fewer staff tend to employ alternative business strategies. There is a clear relationship between having IT staff at a CAH and the types of technologies used. Many CAHs report having difficulty expanding upon HIT functionalities due to the challenges of finding IT staff with healthcare expertise. Most CAHs are in the transition point of planning for or beginning implementation of complex clinical information systems. Strategies for addressing these challenges will need to evolve as the HIT investments by rural hospitals race to keep pace with the goals for the nation.

  4. Visualization of hits/tracks in the ATLAS forward region and forward detectors

    CERN Document Server

    Keck, Thomas

    2013-01-01

    Particle trajectories in the ATLAS forward region are simulated with GEANT4, but mainly hits in sensitive volumes (namely the detectors) are stored in the outputted ROOT files. To visualize hits/tracks in the whole ATLAS forward region a new G4UserAction StoreSimulationHit for GEANT4 was implemented, which stores information about every particle in every simulated step in a collection named SimulationHitCollection. This col- lection can be visualized either directly with ROOT or with VP1. The latter supports now various cuts and the visualization of the hits/tracks together with the forward region Geo- Model and the forward region detector GeoModels.

  5. PageRank, HITS and a unified framework for link analysis

    2001-10-01

    Two popular webpage ranking algorithms are HITS and PageRank. HITS emphasizes mutual reinforcement between authority and hub webpages, while PageRank emphasizes hyperlink weight normalization and web surfing based on random walk models. We systematically generalize/combine these concepts into a unified framework. The ranking framework contains a large algorithm space; HITS and PageRank are two extreme ends in this space. We study several normalized ranking algorithms which are intermediate between HITS and PageRank, and obtain closed-form solutions. We show that, to first order approximation, all ranking algorithms in this framework, including PageRank and HITS, lead to same ranking which is highly correlated with ranking by indegree. These results support the notion that in web resource ranking indegree and outdegree are of fundamental importance. Rankings of webgraphs of different sizes and queries are presented to illustrate our analysis.

  6. Scientific impact: the story of your big hit

    2014-03-01

    A gradual increase in performance through learning and practice characterize most trades, from sport to music or engineering, and common sense suggests this to be true in science as well. This prompts us to ask: what are the precise patterns that lead to scientific excellence? Does performance indeed improve throughout a scientific career? Are there quantifiable signs of an impending scientific hit? Using citation-based measures as a proxy of impact, we show that (i) major discoveries are not preceded by works of increasing impact, nor are followed by work of higher impact, (ii) the precise time ranking of the highest impact work in a scientist's career is uniformly random, with the higher probability to have a major discovery in the middle of scientific careers being due only to changes in productivity, (iii) there is a strong correlation between the highest impact work and average impact of a scientist's work. These findings suggest that the impact of a paper is drawn randomly from an impact distribution that is unique for each scientist. We present a model which allows to reconstruct the individual impact distribution, making possible to create synthetic careers that exhibit the same properties of the real data and to define a ranking based on the overall impact of a scientist.

  11. Statistical Analysis of Probability of Detection Hit/Miss Data for Small Data Sets

    Science.gov (United States)

    Harding, C. A.; Hugo, G. R.

    2003-03-01

    This paper examines the validity of statistical methods for determining nondestructive inspection probability of detection (POD) curves from relatively small hit/miss POD data sets. One method published in the literature is shown to be invalid for analysis of POD hit/miss data. Another standard method is shown to be valid only for data sets containing more than 200 observations. An improved method is proposed which allows robust lower 95% confidence limit POD curves to be determined from data sets containing as few as 50 hit/miss observations.

  19. Platelet senescence is regulated by an internal timer, not damage inflicted by hits.

    Science.gov (United States)

    Dowling, Mark R; Josefsson, Emma C; Henley, Katya J; Hodgkin, Philip D; Kile, Benjamin T

    2010-09-09

    The mechanisms responsible for the brief life span of blood platelets have been a subject of speculation since the 1950s. The most popular hypothesis to date has been the "multiple-hit" model, whereby damage inflicted by external "hits" triggers recognition and clearance by the reticuloendothelial system. Recently, it was demonstrated that platelets contain an apoptotic pathway that mediates their survival in vivo. Using a novel labeling technique to measure population and cohort survival in mice carrying mutations in this pathway, combined with mathematical modeling, we have studied the internal and external control of platelet fate. Our results cast doubt on the veracity of the multiple-hit model. An alternative model, under which platelets are born with an internal "timer," provides a more parsimonious interpretation of the data. Thus, at steady state, platelet senescence is probably the product of internal processes rather than external hits.

    2013-11-01

    Full Text Available Single crystal silicon solar cells are still predominant in the market due to the abundance of silicon on earth and their acceptable efficiency. Different solar-cell structures of single crystalline Si have been investigated to boost efficiency; the heterojunction with intrinsic thin layer (HIT structure is currently the leading technology. The record efficiency values of state-of-the art HIT solar cells have always been based on n-type single-crystalline Si wafers. Improving the efficiency of cells based on p-type single-crystalline Si wafers could provide broader options for the development of HIT solar cells. In this study, we varied the thickness of intrinsic hydrogenated amorphous Si layer to improve the efficiency of HIT solar cells on p-type Si wafers.

    2003-01-01

    HitPeers conotitute a scalable and highly efficient P2P file sharing system in which all the data file can be shared. The center of HitPeers is the Category Tree (CT). CT collects the published information with category. It is flexible enough to let users customize their own local CT. Its hierarchy helps users to find the information they desire most conveniently. To increase the robustness and retain the efficiency, HitPeers will divide the tree into disjoint parts. Every part is a subtree. Some special nodes named Onodes will take charge of the subtree and play the role of a service provider. HitPeers produce more and more Onodes to meet the service demands in the internet-scale distributed environment. This paper will show the profile of the whole system.

  11. Are stripes beneficial? Dazzle camouflage influences perceived speed and hit rates.

    Directory of Open Access Journals (Sweden)

    Bettina von Helversen

    Full Text Available In the animal kingdom, camouflage refers to patterns that help potential prey avoid detection. Mostly camouflage is thought of as helping prey blend in with their background. In contrast, disruptive or dazzle patterns protect moving targets and have been suggested as an evolutionary force in shaping the dorsal patterns of animals. Dazzle patterns, such as stripes and zigzags, are thought to reduce the probability with which moving prey will be captured by impairing predators' perception of speed. We investigated how different patterns of stripes (longitudinal-i.e., parallel to movement direction-and vertical-i.e., perpendicular to movement direction affect the probability with which humans can hit moving objects and if differences in hitting probability are caused by a misperception of speed. A first experiment showed that longitudinally striped objects were hit more often than unicolored objects. However, vertically striped objects did not differ from unicolored objects. A second study examining the link between perceived speed and hitting probability showed that longitudinally and vertically striped objects were both perceived as moving faster and were hit more often than unicolored objects. In sum, our results provide evidence that striped patterns disrupt the perception of speed, which in turn influences how often objects are hit. However, the magnitude and the direction of the effects depend on additional factors such as speed and the task setup.

    User frustration research has been one way of looking into clinicians' experience with health information technology use and interaction. In order to understand how clinician frustration with Health Information Technology (HIT) use occurs, there is the need to explore Human-Computer Interaction (HCI) literature that addresses both frustration and HIT use. In the past three decades, HCI frustration research has increased and expanded. Researchers have done a lot of work to understand emotions, end-user frustration and affect. This paper uses a historical literature review approach to review the origins of emotion and frustration research and explore the research question; Does HCI research on frustration provide insights on clinicians' frustration with HIT interfaces? From the literature review HCI research on emotion and frustration provides additional insights that can indeed help explain user frustration in HIT. Different approaches and HCI perspectives also help frame HIT user frustration research as well as inform HIT system design. The paper concludes with a suggested directions on how future design and research may take.

  13. The impact of Health Information Technology (I-HIT) Scale: the Australian results.

    One of role of the nurse in the clinical setting is that of co-ordinating communication across the healthcare team. On a daily basis nurses interact with the person receiving care, their family members, and multiple care providers thus placing the nurse in the central position with access to a vast array of information on the person. Through this nurses have historically functioned as "information repositories". With the advent of Health Information Technology (HIT) tools there is a potential that HIT could impact interdisciplinary communication, practice efficiency and effectiveness, relationships and workflow in acute care settings [1][3]. In 2005, the HIMSS Nursing Informatics Community developed the I-HIT Scale to measure the impact of HIT on the nursing role and interdisciplinary communication in USA hospitals. In 2007, nursing informatics colleagues from Australia, Finland, Ireland, New Zealand, Scotland and the USA formed a research collaborative to validate the I-HIT in six additional countries. This paper will discuss the background, methodology, results and implications from the Australian I-HIT survey of over 1,100 nurses. The results are currently being analyzed and will be presented at the conference.

    Healthy Living Pharmacies (HLP) were introduced in the United Kingdom (UK) in a further attempt to deliver public health benefits in community pharmacy settings. Central to the initiative are staff trained as Healthy Living Champions (HLC) and this study sought to explore HLC perceptions of positive and negative aspect of their work and the wider scheme. A qualitative study was undertaken with a purposive sample of HLCs working in pathfinder HCPs in the Sheffield area in 2014. Participants were recruited by email to either a focus group (n = 7) held at a training event or later semi-structured one-to-one interviews in pharmacies (n = 6). Four stages of interpretative phenomenological analysis were used to code and identify themes. Four main themes emerged relating to the positive workforce development impact HLPs had upon HLCs themselves and on perceived customer and patient engagement and benefits. Tensions were identified with existing commercial business demands and negative views overall of the pharmacy setting with a perceived lack of not only integration with other services but also awareness among the public and health care staff. HLCs felt empowered and more confident in initiating conversation about health issues with patients, but identified barriers relating to workload, a lack of time to perform their role, isolation, tensions with non-HLC staff and logistical barriers such as poor Internet access. Delivering public health activities through the HLC role in UK pharmacies is associated with several perceived benefits for different stakeholders, but may be threatened by well recognised barriers in UK pharmacies related to the commercial setting. © 2016 Royal Pharmaceutical Society.

  15. Effects of Match Location, Match Status and Quality of Opposition on Regaining Possession in UEFA Champions League

    Full Text Available The present study aimed to examine the independent and interactive effects of match location, match status, and quality of opposition on regaining possession, analysed by the type and zone of ball recovery, in matches played in the 2011-2012 UEFA Champions League. Twenty-eight matches of the knockout phase were evaluated post-event using a computerized notational analysis system. Multinomial logistic regression analysis was applied to identify the effects of the previously mentioned situational variables on ball recovery type and zone. Match status and quality of opposition main effects were observed for both dependent variables, while main effects of match location were only evident for ball recovery zone. Additionally, the interactions Match location * Quality of opposition and Match status * Quality of opposition were significant for both type and zone of ball recovery. Better teams employed more proactive defensive strategies, since, even when winning, they tried to sustain their defensive success on actions that aimed to gain the ball from the opponents. Results emphasized the tendency for home and losing teams to defend in more advanced pitch zones. Better-ranked teams were also more effective than worse-ranked teams in applying defensive pressure in more advanced pitch positions. The findings of the study suggest that the defensive strategies used by better teams imply more intense and organized collective processes in order to recover the ball directly from the opposing team. Furthermore, defending away from own goal and near the opponent's one seems to be associated with success in elite soccer.

    Full Text Available Reactive multi-target ‘fragment drugs’ represent critical components of current tuberculosis regimens. These compounds, such as pyrazinamide, are old synthetic antimycobacterials that are activated inside Mycobacterium tuberculosis bacilli and are smaller than the usual drug-like, single-target molecules. Based on the success of small ‘dirty’ drugs in the chemotherapy of tuberculosis, we suggested previously that fragment-based whole cell screens should be introduced in our current antimycobacterial drug discovery efforts. Here, we carried out such a screen and characterized bactericidal activity, selectivity and spectrum of hits we obtained. A library of 1725 fragments was tested at a single concentration for growth inhibitory activity against M. bovis BCG as screening strain and 38 of 116 primary hits were confirmed in dose response analyses to be active against virulent M. tuberculosis. Bacterial kill experiments showed that most hits displayed bactericidal activity at their minimal inhibitory concentration. Cytotoxicity assays established that a large proportion of hits displayed a favorable selectivity index for mammalian cells. Importantly, one third of M. tuberculosis active fragments were also active against M. abscessus and M. avium, two emerging non-tuberculous mycobacterial pathogens, opening the opportunity to develop broad spectrum antimycobacterials. Activity determination against Gram positive (Staphylococcus aureus and Gram negative (Escherichia coli, Klebsiella pneumonia, Acinetobacter baumanii, Pseudomonas aeruginosa bacteria, as well as fungi (Candida albicans, Cryptococcus neoformans showed only a small overlap indicating a generally narrow spectrum of these novel antimicrobial hits for mycobacteria. In conclusion, we carried out the first fragment-based whole cell screen against bacteria and identified a substantial number of hits with excellent physicochemical properties and dual activity against M. tuberculosis and

    Molecular size and net charge of isoforms of pathogenesis-related (PR) chitinase, beta-1,3-glucanase and peroxidase were studied in uninfected barley (Hordeum vulgare L., v. Karat) leaves and in barley leaves infected with the pathogenic fungus Drechslera teres f. teres (Sacch.) Shoem. Molecular characteristics were determined by time-dependent polyacrylamide gradient gel electrophoresis under native conditions and by applying an extended version of the computer program MOL-MASS (Rothe, G. M., Weidmann, H., Electrophoresis 1991, 12, 703-709). Uninfected barley leaves contained predominantly one peroxidase isozyme but also three very weak peroxidases. Activities of all of these three peroxidases increased considerably after infection with Drechslera teres. The molecular masses of peroxidases 1 and 3 were estimated to be 38 +/- 5 and 42 +/- 7 kDa and their apparent valences at pH 8.4 were Z = 3.13 and 3.20, respectively. Amongst the chitinase isoforms, chitinase 1 and chitinase 2 appeared after infection, while chitinase 3 was also observed in uninfected leaves of barley. The molecular mass of chitinase 3 (31 +/- 6 kDa; f/fo = 1.20) was larger than that of chitinase 1 (20 +/- 2 kDa; f/fo = 1.04) and chitinase 2 (23 +/- 3 kDa; f/fo = 1.06). The valence of constitutive chitinase 3 (Z = 1.44 +/- 0.81) at pH 8.4 was lower than that of adaptive chitinase 1 (Z = 3.27 +/- 1.02) and chitinase 2 (Z = 2.96 +/- 1.38). Infection of barley leaves with Drechslera teres also induced the hydrolytic enzyme beta-1,3-glucanase 1; beta-1,3-glucanase 2 appeared in uninfected and in infected leaves. Constitutive beta-1,3-glucanase 2 was smaller (molecular mass 19 +/- kDa; f/fo = 1.05) than adaptive beta-1,3-glucanase 1 (molecular mass 26 +/- 4 kDa; f/fo = 1.07). The valence of adaptive beta-1,3-glucanase 1 (Z = 9.58 +/- 4.17) was approximately threefold that of beta-1,3-glucanase 2 (Z = 2.80 +/- 0.93).

  19. Atomic features of an autoantigen in heparin-induced thrombocytopenia (HIT).

    2016-07-01

    Autoantigen development is poorly understood at the atomic level. Heparin-induced thrombocytopenia (HIT) is an autoimmune thrombotic disorder caused by antibodies to an antigen composed of platelet factor 4 (PF4) and heparin or cellular glycosaminoglycans (GAGs). In solution, PF4 exists as an equilibrium among monomers, dimers and tetramers. Structural studies of these interacting components helped delineate a multi-step process involved in the pathogenesis of HIT. First, heparin binds to the 'closed' end of the PF4 tetramer and stabilizes its conformation; exposing the 'open' end. Second, PF4 arrays along heparin/GAG chains, which approximate tetramers, form large antigenic complexes that enhance antibody avidity. Third, pathogenic HIT antibodies bind to the 'open' end of stabilized PF4 tetramers to form an IgG/PF4/heparin ternary immune complex and also to propagate the formation of 'ultralarge immune complexes' (ULCs) that contain multiple IgG antibodies. Fourth, ULCs signal through FcγRIIA receptors, activating platelets and monocytes directly and generating thrombin, which transactivates hematopoietic and endothelial cells. A non-pathogenic anti-PF4 antibody prevents tetramer formation, binding of pathogenic antibody, platelet activation and thrombosis, providing a new approach to manage HIT. An improved understanding of the pathogenesis of HIT may lead to novel diagnostics and therapeutics for this autoimmune disease.

    We describe a Gorlin syndrome (GS) case with two different second hit mutations of PTCH1, one in a keratocystic odontogenic tumor (KCOT) and the other in an ovarian leiomyoma. GS is a rare genetic condition manifesting as multiple basal cell nevi associated with other features such as medulloblastomas, skeletal abnormalities, and ovarian fibromas. A 21-year-old Japanese woman with a history of two KCOTs was diagnosed with GS according to clinical criteria. A PTCH1 mutation, c.1427del T, was detected in peripheral blood. A novel PTCH1 mutation, c.264_265insAATA, had been found in the maxillary KCOT as a second hit mutation. More recently, the ovarian tumor was detected during a gynecological examination. Laparoscopic adnexectomy was performed, and the pathological diagnosis of the ovarian tumor was leiomyoma. Interestingly, another novel mutation, loss of heterozygosity spanning from 9q22.32 to 9q31.2, including PTCH1 and 89 other genes, was detected in this ovarian tumor, providing evidence of a second hit mutation. This is the first report describing a GS-associated ovarian tumor carrying a second hit in the PTCH1 region. We anticipate that accumulation of more cases will clarify the importance of second hit mutations in ovarian tumor formation in GS.

    High Throughput Screening (HTS) is a common approach in life sciences to discover chemical matter that modulates a biological target or phenotype. However, low assay throughput, reagents cost, or a flowchart that can deal with only a limited number of hits may impair screening large numbers of compounds. In this case, a subset of compounds is assayed, and in silico models are utilized to aid in iterative screening design, usually to expand around the found hits and enrich subsequent rounds for relevant chemical matter. However, this may lead to an overly narrow focus, and the diversity of compounds sampled in subsequent iterations may suffer. Active learning has been recently successfully applied in drug discovery with the goal of sampling diverse chemical space to improve model performance. Here we introduce a robust and straightforward iterative screening protocol based on naı̈ve Bayes models. Instead of following up on the compounds with the highest scores in the in silico model, we pursue compounds with very low but positive values. This includes unique chemotypes of weakly active compounds that enhance the applicability domain of the model and increase the cumulative hit rates. We show in a retrospective application to 81 Novartis assays that this protocol leads to consistently higher compound and scaffold hit rates compared to a standard expansion around hits or an active learning approach. We recommend using the weak reinforcement strategy introduced herein for iterative screening workflows.

    Efforts to achieve effective and meaningful patient and public involvement (PPI) in healthcare have existed for nearly a century, albeit with limited success. This brief commentary discusses a recent paper by Carter and Martin exploring the "Challenges Facing Healthwatch, a New Consumer Champion in England," and places these challenges in the context of the broader struggle to give a voice to healthcare consumers and citizens. With an overview of what can go right and-perhaps more importantly-what can go wrong, the question remains: will Healthwatch-and other PPI efforts in healthcare-represent the voice of consumers or citizens and will it matter?

    The J-PET detector being developed at Jagiellonian University, is a Positron Emission Tomograph composed of the long strips of polymer scintillators. At the same time it is a detector system which will be used for studies of the decays of positronium atoms. The shape of photomultiplier signals depends on the hit-time and hit-position of the gamma quantum. In order to take advantage of this fact a dedicated sampling front-end electronics which enables to sample signals in voltage domain with the time precision of about 20 ps and novel reconstruction method based on the comparison of examined signal with the model signals stored in the library has been developed. As a measure of the similarity we use the Mahalanobis distance. The achievable position and time-resolution depends on number and values of the threshold levels at which the signal is sampled. A reconstruction method, as well as preliminary results are presented and discussed.

    Many companies have posted impressive top-line growth over the past two decades in their respective economic regions--for instance, Wal-Mart in North America, BP in Europe, Toyota in Asia, and News Corporation in the Southern Hemisphere. But which were the best at converting all of that revenue growth into shareholder value? Harvard Business Review asked C. Bennett Stewart III, the senior partner of the consulting firm Stern Stewart & Company, and his colleagues to come up with the answer. For the period 1983 to 2003, they assembled a list of the top 20 high-growth value adders (and laggards) in each of the four regions cited above. Their calculations gave equal weight to companies' revenue growth and market-value-added scores, revealing the important effect of region on the performance of companies in the same industry. For instance, while automakers are positioned high on the Asian list of high-growth value adders, U.S. carmakers GM and Ford--each of which reported revenue growth in excess of 100 billion dollars between 1983 and 2003--are among the value laggards on the North American list, as are DaimlerChrysler and Volkswagen on the European list. The Japanese win through better efficiency, higher quality, and narrower product mixes, the author says. And while there are four telecom companies represented among the European high-growth value adders, there are none on the North American list. That's probably because the European telecoms enjoyed more protective regulation, made fewer high-priced acquisitions, and didn't bet as big on the overblown dot-com economy, the author says.

    Mathematical model for hit phenomena presented by A Ishii et al in 2012 has been extended to analyze and predict a lot of hit subject using social network system. The equation for each individual consumers is assumed and the equation of social response to each hit subject is derived as stochastic process of statistical physics. The advertisement effect is included as external force and the communication effects are included as two-body and three-body interaction. The applications of this model are demonstrated for analyzing population of weekly TV drama. Including both the realtime view data and the playback view data, we found that the indirect communication correlate strongly to the TV viewing rate data for recent Japanese 20 TV drama.

    Miotto, Jose M; Altmann, Eduardo G

    2016-01-01

    The competition for the attention of users is a central element of the Internet. Crucial issues are the origin and predictability of big hits, the few items that capture a big portion of the total attention. We address these issues analyzing 10 million time series of videos' views from YouTube. We find that the average gain of views is linearly proportional to the number of views a video already has, in agreement with usual rich-get-richer mechanisms and Gibrat's law, but this fails to explain the prevalence of big hits. The reason is that the fluctuations around the average views are themselves heavy tailed. Based on these empirical observations, we propose a stochastic differential equation with Le\\'evy noise as a model of the dynamics of videos. We show how this model is substantially better in estimating the probability of an ordinary item becoming a big hit, which is considerably underestimated in the traditional proportional-growth models.

  13. A method of combining SE-tree to compute all minimal hitting sets

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    In model-based diagnosis, the candidate diagnostic results are generally characterized by all minimal hitting sets for the collection of all conflict sets. In this paper, a new method is proposed to judge a hitting set by the number of conflict sets corresponding to components, and the computing procedure is formalized by combining revised SE-tree (set enumeration tree) with dosed nodes to generate all minimal hitting sets. Results show that because closed nodes are added into SE-tree, the search efficiency is highly improved. Furthermore, the proposed method is easy to be understood and implemented. Compared with other effective algorithms with completeness in some experimental tests, the diagnosis efficiency of our proposed method is higher, particularly for single- and double-fault diagnosis.

    The Super-FRS beam diagnostics system supports the set up and adjustment of the separator and provides tracking and event-by-event particle identification. A TPC-type detector with GEM amplification and with multi-hit single-strip readout is proposed to be used as a tracking detector. The main challenges for such a detector are position resolution below 1 mm, high dynamic range (1000) and high-efficiency tracking up to 10 MHz ion rate. One of the planned improvements towards a high-rate capability of single-ion tracking is the multi-hit readout of the TPC detectors. Present TPC detectors with delay-line readout were tested with multihit electronics at the GSI fragment separator FRS with Au beam at 1 GeV/nucl. up to 150 kHz. Results are presented in comparison to single-hit readout.

    2016-01-01

    Track reconstruction in high track multiplicity environments at current and future high rate particle physics experiments is a big challenge and very time consuming. The search for track seeds and the fitting of track candidates are usually the most time consuming steps in the track reconstruction. Here, a new and fast track reconstruction method based on hit triplets is proposed which exploits a three-dimensional fit model including multiple scattering and hit uncertainties from the very start, including the search for track seeds. The hit triplet based reconstruction method assumes a homogeneous magnetic field which allows to give an analytical solutions for the triplet fit result. This method is highly parallelizable, needs fewer operations than other standard track reconstruction methods and is therefore ideal for the implementation on parallel computing architectures. The proposed track reconstruction algorithm has been studied in the context of the Mu3e-experiment and a typical LHC experiment.

    2013-02-01

    Nonsteroidal anti-inflammatory drugs (NSAIDs) can cause serious gastrointestinal (GI) injury including jejunal/ileal mucosal ulceration, bleeding, and even perforation in susceptible patients. The underlying mechanisms are largely unknown, but they are distinct from those related to gastric injury. Based on recent insights from experimental models, including genetics and pharmacology in rodents typically exposed to diclofenac, indomethacin, or naproxen, we propose a multiple-hit pathogenesis of NSAID enteropathy. The multiple hits start with an initial pharmacokinetic determinant caused by vectorial hepatobiliary excretion and delivery of glucuronidated NSAID or oxidative metabolite conjugates to the distal small intestinal lumen, where bacterial β-glucuronidase produces critical aglycones. The released aglycones are then taken up by enterocytes and further metabolized by intestinal cytochrome P450s to potentially reactive intermediates. The "first hit" is caused by the NSAID and/or oxidative metabolites that induce severe endoplasmic reticulum stress or mitochondrial stress and lead to cell death. The "second hit" is created by the significant subsequent inflammatory response that would follow such a first-hit injury. Based on these putative mechanisms, strategies have been developed to protect the enterocytes from being exposed to the parent NSAID and/or oxidative metabolites. Among these, a novel strategy already demonstrated in a murine model is the selective disruption of bacteria-specific β-glucuronidases with a novel small molecule inhibitor that does not harm the bacteria and that alleviates NSAID-induced enteropathy. Such mechanism-based strategies require further investigation but provide potential avenues for the alleviation of the GI toxicity caused by multiple NSAID hits.

  20. On hitting children: a review of corporal punishment in the United States.

    Science.gov (United States)

    Knox, Michele

    2010-01-01

    Research has clearly demonstrated associations between corporal punishment of children and maladaptive behavior patterns such as aggression and delinquency. Hitting children is an act of violence and a clear violation of children's human rights. In this article, the position of the United States on corporal punishment of children is discussed. Professional and international progress on ending corporal punishment is explained, and the relationship between corporal punishment and child abuse is discussed. An appeal is made for prevention efforts such as parent education and removal of social sanctions for hitting children that may hold significant promise for preventing child maltreatment.

  1. Study of neutron-induced background hits in the CMS endcap muon system

    CERN Document Server

    Dasgupta, Abhigyan

    2017-01-01

    Among the many challenges arising from the high luminosities of the HL-LHC is the impact of increased hit rates in the cathode strip chambers of the CMS endcap muon system. These chambers detect muons as part of the CMS muon trigger, and their data is used offline for muon track reconstruction. Neutrons (both fast and thermal) induce background hits via nuclear interactions and capture, followed by gamma emission and (mainly) Compton scatter off electrons that subsequently ionize the chamber gas. This note presents recent efforts to improve the understanding of such neutron-induced background through detailed comparison of CMS pp collision data and GEANT4 simulation.

  4. "The Major Forces that Need to Back Medical Tourism Were … in Alignment": Championing Development of Barbados's Medical Tourism Sector.

    Science.gov (United States)

    Johnston, Rory; Crooks, Valorie A; Snyder, Jeremy; Whitmore, Rebecca

    2015-01-01

    Governments around the world have expressed interest in developing local medical tourism sectors, framing the industry as an opportunity for economic growth and health system improvement. This article addresses questions about how the desire to develop a medical tourism sector in a country emerges and which stakeholders are involved in both creating momentum and informing its progress. Presenting a thematic analysis of 19 key informant interviews conducted with domestic and international stakeholders in Barbados's medical tourism sector in 2011, we examine the roles that "actors" and "champions" at home and abroad have played in the sector's development. Physicians and the Barbadian government, along with international investors, the Medical Tourism Association, and development agencies, have promoted the industry, while actors such as medical tourists and international hospital accreditation companies are passively framing the terms of how medical tourism is unfolding in Barbados. Within this context, we seek to better understand the roles and relationships of various actors and champions implicated in the development of medical tourism in order to provide a more nuanced understanding of how the sector is emerging in Barbados and elsewhere and how its development might impact equitable health system development. © The Author(s) 2015 Reprints and permissions:]br]sagepub.co.uk/journalsPermissions.nav.

    2013-01-01

    Background Broad-spectrum antibiotic administration promotes intestinal colonization of exogenous fungal pathogens in healthy animals and has been recognized as one of the risk factors of invasive fungal infection in clinical settings.It is unclear whether broad-spectrum antibiotic treatment would change the intestinal mycobiota without exogenous fungal challenge in the context of sepsis.Methods We established a rat model of double-hit sepsis using burn injury and endotoxin challenge.Rats with burn injury or double-hit sepsis received imipenem treatment for 3 days or 9 days,and their colon contents were sampled for selective fungal culture and isolation counts.Results Imipenem treatment promoted the overgrowth of the commensal fungus Geotrichum capitatum in rats with burn injury.Imipenem treatment also promoted colon colonization by exogenous fungi in rats with burn injury and double-hit sepsis,including Trichosporon cutaneum,Candida albicans,Candida krusei,and Candida glabrata.A longer duration of imipenem treatment had a stronger impact on colon colonization by exogenous fungi.Conclusion Imipenem treatment facilitates the overgrowth of commensal fungi and colonization by exogenous,potentially pathogenic fungi in the colons of rats with burn injury or double-hit sepsis.

    Protein-RNA interactions have critical roles in all aspects of gene expression. However, applying biochemical methods to understand such interactions in living tissues has been challenging. Here we develop a genome-wide means of mapping protein-RNA binding sites in vivo, by high-throughput sequencing of RNA isolated by crosslinking immunoprecipitation (HITS-CLIP). HITS-CLIP analysis of the neuron-specific splicing factor Nova revealed extremely reproducible RNA-binding maps in multiple mouse brains. These maps provide genome-wide in vivo biochemical footprints confirming the previous prediction that the position of Nova binding determines the outcome of alternative splicing; moreover, they are sufficiently powerful to predict Nova action de novo. HITS-CLIP revealed a large number of Nova-RNA interactions in 3' untranslated regions, leading to the discovery that Nova regulates alternative polyadenylation in the brain. HITS-CLIP, therefore, provides a robust, unbiased means to identify functional protein-RNA interactions in vivo.

  10. Hierarchical virtual screening for the discovery of new molecular scaffolds in antibacterial hit identification.

    Ballester, Pedro J; Mangold, Martina; Howard, Nigel I; Robinson, Richard L Marchese; Abell, Chris; Blumberger, Jochen; Mitchell, John B O

    2012-12-07

    One of the initial steps of modern drug discovery is the identification of small organic molecules able to inhibit a target macromolecule of therapeutic interest. A small proportion of these hits are further developed into lead compounds, which in turn may ultimately lead to a marketed drug. A commonly used screening protocol used for this task is high-throughput screening (HTS). However, the performance of HTS against antibacterial targets has generally been unsatisfactory, with high costs and low rates of hit identification. Here, we present a novel computational methodology that is able to identify a high proportion of structurally diverse inhibitors by searching unusually large molecular databases in a time-, cost- and resource-efficient manner. This virtual screening methodology was tested prospectively on two versions of an antibacterial target (type II dehydroquinase from Mycobacterium tuberculosis and Streptomyces coelicolor), for which HTS has not provided satisfactory results and consequently practically all known inhibitors are derivatives of the same core scaffold. Overall, our protocols identified 100 new inhibitors, with calculated K(i) ranging from 4 to 250 μM (confirmed hit rates are 60% and 62% against each version of the target). Most importantly, over 50 new active molecular scaffolds were discovered that underscore the benefits that a wide application of prospectively validated in silico screening tools is likely to bring to antibacterial hit identification.

    2013-04-01

    The present study investigated bat control of skilled baseball batters during tee batting, faced with an intentional change in target position. Twelve, skilled, male baseball players (M age = 24 yr., SD = 4) participated in the study. Participants were instructed to hit a baseball off a tee 0.8 m from the ground (Hitting condition), and also to deliberately swing just above the ball (Air Swing condition). The task for the participants was to perform, in alternate order, 15 swings at a real baseball on a stationary tee and 15 swings at an imaginary ball that was said to be on top of the real baseball. The participants were instructed to hit the ball toward center field just as they would hit in a game. While most participants could hit the real ball in the sweet area of the bat, only one participant did so in the Air Swing condition. Average distances from the center of the sweet area to ball center at the moment of ball-bat contact in the Air Swing condition (85 mm) were significantly greater than the distance in the Hitting condition (38 mm). The larger error in hitting an imaginary ball in the sweet area could be due to perceptual changes following the batter's altered focus, expectation of a lack of contact, and/or lack of feedback from the swing. It was suggested that baseball batters should be aware of the possible error in hitting accurately when they intentionally shifted the target.

  18. Non-linear relationship of cell hit and transformation probabilities in low dose of inhaled radon progenies

    CERN Document Server

    Balásházy, Imre; Madas, Balázs Gergely; Hofmann, Werner

    2013-01-01

    Cellular hit probabilities of alpha particles emitted by inhaled radon progenies in sensitive bronchial epithelial cell nuclei were simulated at low exposure levels to obtain useful data for the rejection or in support of the linear-non-threshold (LNT) hypothesis. In this study, local distributions of deposited inhaled radon progenies in airway bifurcation models were computed at exposure conditions, which are characteristic of homes and uranium mines. Then, maximum local deposition enhancement factors at bronchial airway bifurcations, expressed as the ratio of local to average deposition densities, were determined to characterize the inhomogeneity of deposition and to elucidate their effect on resulting hit probabilities. The results obtained suggest that in the vicinity of the carinal regions of the central airways the probability of multiple hits can be quite high even at low average doses. Assuming a uniform distribution of activity there are practically no multiple hits and the hit probability as a funct...

    2015-07-01

    Double hit lymphoma or triple hit lymphoma (DHL/THL) is a rare form of aggressive B-Cell Lymphoma. Overexpression of MYC, BCL2 or/and BCL6 due to genomic rearrangements are the key molecular features of DHL/THL. Patients with DHL/THL show very aggressive disease course and poor survival due to the lack of effective treatment modalities. Here, we established new THL cell model and assessed its in vitro growth characteristics along with the DHL cell line in response to potent MYC inhibitors, 10058-F4 and JQ-1, and a BCL2 inhibitor, ABT-199, with or without chemotherapeutic agent vincristine or doxorubicin. We found that 10058-F4, JQ-1 or ABT-199 exposure as a single agent inhibited the growth of DHL/THL cells in a dose-dependent manner. Combined exposure of 10058-F4 or JQ-1 and ABT-199 as well as vincristine or doxorubicin markedly suppressed the growth of DHL/THL cells compared with the single treatment. As assessed by multiple approaches, apoptosis induced by ABT-199, 10058-F4 or JQ-1 was underlying cause of the observed growth suppression. These findings suggest that co-inhibition of MYC and BCL2 signaling is a promising therapeutic strategy for patients with DHL/THL lymphomas. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To examine the safety and efficacy of cangrelor in patients with single-vessel disease (SVD) and multi-vessel disease (MVD). Cangrelor, an intravenous, rapidly acting P2Y12 inhibitor, is superior to clopidogrel in reducing ischemic events among patients receiving percutaneous coronary intervention (PCI). We studied a modified intention to treat population of patients with SVD and MVD from the CHAMPION PHOENIX trial. The primary efficacy outcome was the composite of death, myocardial infarction (MI), ischemia-driven revascularization (IDR), and stent thrombosis (ST) at 48hours. The key safety outcome was non-coronary artery bypass grafting GUSTO severe bleeding at 48hours. Among 10,921 patients, 5,220 (48%) had SVD and 5,701 (52%) had MVD. MVD patients were older and more often had diabetes, hyperlipidemia, hypertension, prior stroke, and prior MI. After adjustment, MVD patients had similar rates of 48-hour death/MI/IDR/ST (6.3% vs 4.2%, adjusted odds ratio [OR] 1.6 [95% CI 0.42-6.06]) and GUSTO severe bleeding (0.1% vs 0.2%, P=.67) compared with SVD patients. Consistent with overall trial findings, cangrelor use reduced ischemic complications in patients with both SVD (3.9% vs 4.5%; OR 0.86, 95% CI 0.65-1.12) and MVD (5.5% vs 7.2%; OR 0.74, 95% CI 0.6-0.92, P-interaction=.43). GUSTO severe bleeding outcomes were not significantly increased with cangrelor or clopidogrel in either SVD or MVD patients. In the CHAMPION PHOENIX trial, MVD and SVD patients had similar ischemic outcomes at 48hours and 30days. Cangrelor consistently reduced ischemic complications in both SVD and MVD patients without a significant increase in GUSTO severe bleeding. CLINICAL PERSPECTIVES. Copyright © 2017 Elsevier Inc.

    Over the last decade, Britain has undergone reforms to promote engagement in local structures of governance. These reforms have encouraged the promotion of active citizenship and have been central to the government's public service modernisation agenda. This article presents the findings from a study evaluating a pilot outreach intervention which adopted a community engagement model to address the mental health needs of African and African Caribbean groups, which entailed a partnership between faith-based organisations, local public services and community organisations to co-produce the pilot project. Lay people were trained to raise awareness about mental health among these communities in South London. Between 2012 and 2013, a qualitative participatory approach was used to evaluate the pilot project, which enabled a researcher to take part in the engagement phase of the pilot project, and the project co-ordinators to be involved in the research process. Semi-structured, one-to-one interviews were carried out with 13 community and well-being champions (CWBCs) recruited from African and African Caribbean communities (seven male and six female). This study examines the impact of the relationship between the intervention and community through the participants' engagement in the pilot outreach project and the action undertaken as champions. We found that although CWBCs used circles of influence to share ideas about mental health and well-being and to encourage change, they encountered resistance on the part of the people they engaged with, which resulted from a lack of knowledge about mental health, taboos and ascribed stigma. We argue that CWBCs acted as healthy examples to communicate mental health knowledge to those approached, but that they needed to be equipped with bespoke communication skills to be able to talk about such sensitive issues as mental health. © 2015 The Authors.

    Background In the mid-2000s, neonatal mortality accounted for almost 40% of deaths of children under 5 years worldwide, and constituted 65% of infant deaths in India. The neonatal mortality rate in Andhra Pradesh was 44 per 1,000 live births, and was higher in the rural areas and tribal regions, such as the Nagarkurnool division of Mahabubnagar district (which became Nagarkurnool district in Telangana in 2014). The aim of the CHAMPION trial was to investigate whether a package of interventions comprising community health promotion and provision of health services (including outreach and facility-based care) could lead to a reduction of the order of 25% in neonatal mortality. Methods and findings The design was a trial in which villages (clusters) in Nagarkurnool with a population < 2,500 were randomised to the CHAMPION package of health interventions or to the control arm (in which children aged 6–9 years were provided with educational interventions—the STRIPES trial). A woman was eligible for the CHAMPION package if she was married and <50 years old, neither she nor her husband had had a family planning operation, and she resided in a trial village at the time of a baseline survey before randomisation or married into the village after randomisation. The CHAMPION intervention package comprised community health promotion (including health education via village health worker–led participatory discussion groups) and provision of health services (including outreach, with mobile teams providing antenatal check-ups, and facility-based care, with subsidised access to non-public health centres [NPHCs]). Villages were stratified by travel time to the nearest NPHC and tribal status, and randomised (1:1) within strata. The primary outcome was neonatal mortality. Secondary outcomes included maternal mortality, causes of death, health knowledge, health practices including health service usage, satisfaction with care, and costs. The baseline survey (enumeration) was

    Individuals in free societies frequently exhibit striking coordination when making independent decisions en masse. Examples include the regular appearance of hit products or memes with substantially higher popularity compared to their otherwise equivalent competitors or extreme polarization in public opinion. Such segregation of events manifests as bimodality in the distribution of collective choices. Here we quantify how apparently independent choices made by individuals result in a significantly polarized but stable distribution of success in the context of the box-office performance of movies and show that it is an emergent feature of a system of noninteracting agents who respond to sequentially arriving signals. The aggregate response exhibits extreme variability amplifying much smaller differences in individual cost of adoption. Due to self-organization of the competitive landscape, most events elicit only a muted response but a few stimulate widespread adoption, emerging as "hits".

    Full Text Available Recently it was shown that the lower Hausdorff metric (uniform topology is generated by families of uniformly discrete sets as hit sets. This result leads to a new hypertopology which is the join of the above topology and the upper Vietoris topology. This uniformly discrete hit-and-miss hypertopology is coarser than the locally finite hypertopology and finer than both Hausdorff metric (uniform topology and Vietoris topology. In this paper this new hypertopology is studied. Here is a Hasse diagram in which each arrow goes from a coarser topology to a finer one and equality follows UC or TB as indicated. The diagram clearly shows that the new (underlined topology provides the missing link.

    Successful health information technology (HIT) implementations need to be informed on the context of use and on users' attitudes. To this end, we developed the CLinical Computer Systems Survey (CLICS) instrument. CLICS reflects a socio-technical view of HIT adoption, and is designed to encompass all members of the clinical team. We used the survey in a large English hospital as part of its internal evaluation of the implementation of an electronic patient record system (EPR). The survey revealed extent and type of use of the EPR; how it related to and integrated with other existing systems; and people's views on its use, usability and emergent safety issues. Significantly, participants really appreciated 'being asked'. They also reminded us of the wider range of administrative roles engaged with EPR. This observation reveals pertinent questions as to our understanding of the boundaries between administrative tasks and clinical medicine - what we propose as the field of 'administrative medicine'.

    Drift chambers operated with helium-based gas mixtures represent a common solution for tracking charged particles keeping the material budget in the sensitive volume to a minimum. The drawback of this solution is the worsening of the spatial resolution due to primary ionisation fluctuations, which is a limiting factor for high granularity drift chambers like the MEG II tracker. We report on the measurements performed on three different prototypes of the MEG II drift chamber aimed at determining the achievable single-hit resolution. The prototypes were operated with helium/isobutane gas mixtures and exposed to cosmic rays, electron beams and radioactive sources. Direct measurements of the single hit resolution performed with an external tracker returned a value of 110 $\\mu$m, consistent with the values obtained with indirect measurements performed with the other prototypes.

    With the rapidly growing number of data publishers, the process of harvesting and indexing information to offer advanced search and discovery becomes a critical bottleneck in globally distributed primary biodiversity data infrastructures. The Global Biodiversity Information Facility (GBIF) implemented a Harvesting and Indexing Toolkit (HIT), which largely automates data harvesting activities for hundreds of collection and observational data providers. The team of the Botanic Garden and Botanical Museum Berlin-Dahlem has extended this well-established system with a range of additional functions, including improved processing of multiple taxon identifications, the ability to represent associations between specimen and observation units, new data quality control and new reporting capabilities. The open source software B-HIT can be freely installed and used for setting up thematic networks serving the demands of particular user groups.

    A method is presented to precisely reconstruct charge spectra with pixel detectors using binary hit information of individual pixels. The method is independent of the charge information provided by the readout circuitry and has a resolution mainly limited by the electronic noise. It relies on the ability to change the detection threshold in small steps while counting hits from a particle source. The errors are addressed and the performance of the method is shown based on measurements with the ATLAS pixel chip FE-I4 bump bonded to a 230 {\\mu}m 3D-silicon sensor. Charge spectra from radioactive sources and from electron beams are presented serving as examples. It is demonstrated that a charge resolution ({\\sigma}<200 e) close to the electronic noise of the ATLAS FE-I4 pixel chip can be achieved.

    The correction or removal of signal errors in high-throughput screening (HTS) data is critical to the identification of high-quality lead candidates. Although a number of strategies have been previously developed to correct systematic errors and to remove screening artifacts, they are not universally effective and still require fair amount of human intervention. We introduce a fully automated quality control (QC) pipeline that can correct generic interplate systematic errors and remove intraplate random artifacts. The new pipeline was first applied to ~100 large-scale historical HTS assays; in silico analysis showed auto-QC led to a noticeably stronger structure-activity relationship. The method was further tested in several independent HTS runs, where QC results were sampled for experimental validation. Significantly increased hit confirmation rates were obtained after the QC steps, confirming that the proposed method was effective in enriching true-positive hits. An implementation of the algorithm is available to the screening community.

    Results: It was noted that the respiratory rate, and tumour necrosis factor-α (TNF-α levels were significantly higher at 4 h in the dual hit group as compared to LPS, OA and control groups. Interleukin-6 (IL-6 levels were significantly higher in the dual hit group as compared to LPS at 8 and 24 h, OA at 8 h and control (at all time intervals group. IL-1β levels were significantly higher in LPS and dual hit groups at all time intervals, but not in OA and control groups. The injury induced in dual hit group was earlier and more sustained as compared to LPS and OA alone. Interpretation & conclusions: The lung pathology and changes in respiration functions produced by the dual hit model were closer to the diagnostic criteria of ALI/ARDS in terms of clinical manifestations and pulmonary injury and the injury persisted longer as compared to LPS and OA single hit model. Therefore, the ARDS model produced by the dual hit method was closer to the diagnostic criteria of ARDS in terms of clinical manifestations and pulmonary injury.

    The Monte Carlo particle transport code SHIELD-HIT12A is designed to simulate therapeutic beams for cancer radiotherapy with fast ions. SHIELD-HIT12A allows creation of antiproton beam kernels for the treatment planning system TRiP98, but first it must be benchmarked against experimental data. An experimental depth dose curve obtained by the AD-4/ACE collaboration was compared with an earlier version of SHIELD-HIT, but since then inelastic annihilation cross sections for antiprotons have been updated and a more detailed geometric model of the AD-4/ACE experiment was applied. Furthermore, the Fermi–Teller Z-law, which is implemented by default in SHIELD-HIT12A has been shown not to be a good approximation for the capture probability of negative projectiles by nuclei. We investigate other theories which have been developed, and give a better agreement with experimental findings. The consequence of these updates is tested by comparing simulated data with the antiproton depth dose curve in water. It is found that the implementation of these new capture probabilities results in an overestimation of the depth dose curve in the Bragg peak. This can be mitigated by scaling the antiproton collision cross sections, which restores the agreement, but some small deviations still remain. Best agreement is achieved by using the most recent antiproton collision cross sections and the Fermi–Teller Z-law, even if experimental data conclude that the Z-law is inadequately describing annihilation on compounds. We conclude that more experimental cross section data are needed in the lower energy range in order to resolve this contradiction, ideally combined with more rigorous models for annihilation on compounds.

    Full Text Available Abstract Background The use of Information and Communication Technology (ICT or e-Health is seen as essential for a modern, cost-effective health service. However, there are well documented problems with implementation of e-Health initiatives, despite the existence of a great deal of research into how best to implement e-Health (an example of the gap between research and practice. This paper reports on the development and formative evaluation of an e-Health Implementation Toolkit (e-HIT which aims to summarise and synthesise new and existing research on implementation of e-Health initiatives, and present it to senior managers in a user-friendly format. Results The content of the e-HIT was derived by combining data from a systematic review of reviews of barriers and facilitators to implementation of e-Health initiatives with qualitative data derived from interviews of "implementers", that is people who had been charged with implementing an e-Health initiative. These data were summarised, synthesised and combined with the constructs from the Normalisation Process Model. The software for the toolkit was developed by a commercial company (RocketScience. Formative evaluation was undertaken by obtaining user feedback. There are three components to the toolkit - a section on background and instructions for use aimed at novice users; the toolkit itself; and the report generated by completing the toolkit. It is available to download from http://www.ucl.ac.uk/pcph/research/ehealth/documents/e-HIT.xls Conclusions The e-HIT shows potential as a tool for enhancing future e-Health implementations. Further work is needed to make it fully web-enabled, and to determine its predictive potential for future implementations.

    The risk of collision between pedestrians and powered two-wheelers is poorly understood today. The objective of this research is to determine the risk for powered two-wheeler drivers of hitting and injuring a pedestrian per kilometer driven in towns and to compare this risk with that run by four-wheeled vehicle drivers. Using the bodily injury accidents recorded by the police on nine roads in the city of Marseille in 2011 and a campaign of observations of powered two-wheeler traffic, we estimated the risk per kilometer driven by powered two-wheeler drivers of hitting a pedestrian and compared it with the risk run by four-wheeled vehicle drivers. The results show that the risk for powered two-wheeler drivers of hitting and injuring a pedestrian is significantly higher than the risk run by four-wheeled vehicle drivers. On the nine roads studied, it is on average 3.33 times higher (95% CI: 1.63; 6.78). Taking four more years into account made it possible to consolidate these results and to tighten the confidence interval. There does indeed seem to be problems in the interactions between pedestrians and powered two-wheeler users in urban traffic. These interaction problems lead to a higher risk of hitting and injuring a pedestrian for powered two-wheeler drivers than for four-wheeled vehicle drivers. The analysis of the police reports suggests that part of this increased risk comes from filtering maneuvers by powered two-wheelers. Possible countermeasures deal with the urban street layout. Measures consisting in reducing the width and the number of traffic lanes to a strict minimum and installing medians or pedestrian islands could be an effective way for the prevention of urban accidents between pedestrians and powered two-wheelers.

    The goal of this study is to describe a framework that allows decision makers to efficiently evaluate factors that affect Electronic Health Record (EHR) adoption and test suitable interventions; specifically financial incentives. The United States healthcare delivery system is experiencing a transformation to improve population health. There is strong agreement that "meaningful use" of Health Information Technology (HIT) is a major enabler in this effort. However it's also understood that the high cost of implementing an EHR is an obstacle for adoption. To help understand these complexities we developed a simulation model designed to capture the dynamic nature of policy interventions that affect the adoption of EHR. We found that "Effective" use of HIT approaches break-even-point and larger clinic revenue many times faster that "average" or "poor" use of HIT. This study uses a systems perspective to the evaluate EHR adoption process through the "meaningful use" redesign as proposed in the American Reinvestment and Recovery Act 2009 in the United States healthcare industry by utilizing the System Dynamics methodology and Scenario Analysis.

    For the planned high luminosity upgrade of the Large Hadron Collider (LHC), a significant performance improvement of the detectors is required, including new tracker and trigger systems that makes use of charged track information early on. In this note we explore the principle of real time track reconstruction integrated in the readout electronics. A prototype was built using the silicon strip sensor for the ATLAS phase-II upgrade. The real time tracker is not the baseline for ATLAS but is nevertheless of interest, as the upgraded trigger design has not yet been finalized. For this, a new readout scheme in parallel with conventional readout, called the Fast Cluster Finder (FCF), was included in the latest prototype of the ATLAS strip detector readout chip (ABC130). The FCF is capable of finding hits within 6 ns and transmitting the found hit information synchronously every 25 ns. Using the FCF together with external correlation logic makes it possible to look for pairs of hits consistent with tracks from the interaction point above a transverse momentum threshold. A correlator logic finds correlations between two closely spaced parallel sensors, a “doublet”, and can generate information used as input to a lowest level trigger decision. Such a correlator logic was developed as part of a demonstrator and was successfully tested in an electron beam. The results of this test beam experiment proved the concept of the real time track vector processor with FCF.

  20. The danger signal plus DNA damage two-hit hypothesis for chronic inflammation in COPD.

    Inflammation in chronic obstructive pulmonary disease (COPD) is thought to originate from the activation of innate immunity by a danger signal (first hit), although this mechanism does not readily explain why the inflammation becomes chronic. Here, we propose a two-hit hypothesis explaining why inflammation becomes chronic in patients with COPD. A more severe degree of inflammation exists in the lungs of patients who develop COPD than in the lungs of healthy smokers, and the large amounts of reactive oxygen species and reactive nitrogen species released from inflammatory cells are likely to induce DNA double-strand breaks (second hit) in the airways and pulmonary alveolar cells, causing apoptosis and cell senescence. The DNA damage response and senescence-associated secretory phenotype (SASP) are also likely to be activated, resulting in the production of pro-inflammatory cytokines. These pro-inflammatory cytokines further stimulate inflammatory cell infiltration, intensifying cell senescence and SASP through a positive-feedback mechanism. This vicious cycle, characterised by mutually reinforcing inflammation and DNA damage, may cause the inflammation in COPD patients to become chronic. Our hypothesis helps explain why COPD tends to occur in the elderly, why the inflammation worsens progressively, why inflammation continues even after smoking cessation, and why COPD is associated with lung cancer.

    Accurately quantifying the goodness of music based on the seemingly subjective taste of the public is a multi-million industry. Recording companies can make sound decisions on which songs or artists to prioritize if accurate forecasting is achieved. We extract 56 single-valued musical features (e.g. pitch and tempo) from 380 Original Pilipino Music (OPM) songs (190 are hit songs) released from 2004 to 2006. Based on an effect size criterion which measures a variable's discriminating power, the 20 highest ranked features are fed to a classifier tasked to predict hit songs. We show that regardless of musical genre, a trained feed-forward neural network (NN) can predict potential hit songs with an average accuracy of ΦNN = 81%. The accuracy is about +20% higher than those of standard classifiers such as linear discriminant analysis (LDA, ΦLDA = 61%) and classification and regression trees (CART, ΦCART = 57%). Both LDA and CART are above the proportional chance criterion (PCC, ΦPCC = 50%) but are slightly below the suggested acceptable classifier requirement of 1.25*ΦPCC = 63%. Utilizing a similar procedure, we demonstrate that different genres (ballad, alternative rock or rock) of OPM songs can be automatically classified with near perfect accuracy using LDA or NN but only around 77% using CART.

The system was constructed using G2000 and G9 glass scintillators, as well as an electron-multiplying charge-coupled device (EMCCD) camera combined with an inverted microscope with a 10× objective lens. Commercially available G2000 and G9 glass scintillators, which have been reported to exhibit strong photoluminescence at 489, 543, 585, and 622 nm as a result of the Tb3+ f-f transition, were employed for highly accurate ionized particle detection. The EMCCD camera had a resolution of 512 × 512 pixels, each with a size of 16 μm × 16 μm, and a maximum linear gain of 8 × 105 electrons. For 260-MeV Ne, 3 ion hits/s were detected by our system. The intensity of the ionoluminescence (IL) peak induced by the heavy ions was 140 times the noise intensity. In contrast, the luminous diameter at the full width at half maximum (FWHM) in both the horizontal and vertical directions was calculated to be approximately 4.5 μm. These results suggest that our detection system can accurately detect single-ion hits with a diameter of the order of 1 μm.

    The Helicity Injected Torus - Steady Inductive 3(HIT-SI3)experiment forms and maintains spheromaks via Steady Inductive Helicity Injection (SIHI). Three injector units allow for continuous injection of helicity into a copper flux conserver in order to sustain a spheromak. Firing of the injectors with a phase difference allows finite rotation of the plasma to provide a stabilizing effect. Simulations in the MHD code NIMROD and the fluid-model code PSI-TET provide validation and a basis for interpretation of the observed experimental data. Thompson Scattering (TS) and Far Infrared (FIR) Interferometer systems allow temperature and line-averaged density measurements to be taken. An Ion Doppler Spectroscopy (IDS) system allows measurement of the plasma rotation and velocity. HIT-SI3 data has been used for validation of IDCD predictions, in particular the projected impedance of helicity injectors according to the theory. The experimental impedances have been calculated here for the first time for different HIT-SI3 regimes. Such experimental evidence will contribute to the design of future experiments employing IDCD as a current-drive mechanism. Work supported by the D.O.E., Office of Science, Office of Fusion Science.

  4. Enhancing hit identification in Mycobacterium tuberculosis drug discovery using validated dual-event Bayesian models.

    Directory of Open Access Journals (Sweden)

    Sean Ekins

    Full Text Available High-throughput screening (HTS in whole cells is widely pursued to find compounds active against Mycobacterium tuberculosis (Mtb for further development towards new tuberculosis (TB drugs. Hit rates from these screens, usually conducted at 10 to 25 µM concentrations, typically range from less than 1% to the low single digits. New approaches to increase the efficiency of hit identification are urgently needed to learn from past screening data. The pharmaceutical industry has for many years taken advantage of computational approaches to optimize compound libraries for in vitro testing, a practice not fully embraced by academic laboratories in the search for new TB drugs. Adapting these proven approaches, we have recently built and validated Bayesian machine learning models for predicting compounds with activity against Mtb based on publicly available large-scale HTS data from the Tuberculosis Antimicrobial Acquisition Coordinating Facility. We now demonstrate the largest prospective validation to date in which we computationally screened 82,403 molecules with these Bayesian models, assayed a total of 550 molecules in vitro, and identified 124 actives against Mtb. Individual hit rates for the different datasets varied from 15-28%. We have identified several FDA approved and late stage clinical candidate kinase inhibitors with activity against Mtb which may represent starting points for further optimization. The computational models developed herein and the commercially available molecules derived from them are now available to any group pursuing Mtb drug discovery.

    A real-time position detection system has been developed for a single-ion hit. The system is composed of a position sensitive camera unit and a luminescent scintillator. The camera unit includes 512 × 512 pixel electron-multiplier charge-coupled device, an image intensifier tube, and an object lens with a working distance of 101 mm. To obtain a highly sensitive luminescent scintillator for the detection of a single ion in the mega-electron-volt region, we investigate the photoluminescence properties of α-Al{sub 2}O{sub 3} single-crystals implanted with Eu(Al{sub 2}O{sub 3}:Eu) at a fluence ranging from 10{sup 14} to 10{sup 16} cm{sup −2}. The Al{sub 2}O{sub 3}:Eu samples were annealed at temperature from 500°C to 900°C. The results of 15-MeV O single-ion hit experiments using Al{sub 2}O{sub 3}:Eu with a fluence of 3.0 × 10{sup 16} cm{sup −2} annealed for 0.5 h at 600°C indicate that our system is sufficiently sensitive to detect the single-ion hit with a spatial resolution of 1 μm in real time.

    Thrombocytopenia and thromboembolism(s) may develop in heparin immune-mediated thrombocytopenia (HIT) patients after reexposure to heparin. At the Onassis Cardiac Surgery Center, 530 out of 17,000 patients requiring heart surgery over an 11-year period underwent preoperative HIT assessment by ELISA and a three-point heparin-induced platelet aggregation assay (HIPAG). The screening identified 110 patients with HIT-reactive antibodies, out of which 46 were also thrombocytopenic (true HIT). Cardiac surgery was performed in HIT-positive patients under heparin anticoagulation and iloprost infusion. A control group of 118 HIT-negative patients received heparin but no iloprost during surgery. For the first 20 patients, the dose of iloprost diminishing the HIPAG test to ≤5% was determined prior to surgery by in vitro titration using the patients' own plasma and donor platelets. In parallel, the iloprost "target dose" was also established for each patient intraoperatively, but before heparin administration. Iloprost was infused initially at 3 ng/kg/mL and further adjusted intraoperatively, until ex vivo aggregation reached ≤5%. As a close correlation was observed between the "target dose" identified before surgery and that established intraoperatively, the remaining 90 patients were administered iloprost starting at the presurgery identified "target dose." This process significantly reduced the number of intraoperative HIPAG reassessments needed to determine the iloprost target dose, and reduced surgical time, while maintaining similar primary clinical outcomes to controls. Therefore, infusion of iloprost throughout surgery, under continuous titration, allows cardiac surgery to be undertaken safely using heparin, while avoiding life-threatening iloprost-induced hypotension in patients diagnosed with HIT-reactive antibodies or true HIT. © 2015 Wiley Periodicals, Inc.

    The MEPHISTO chip uses a novel binary architecture to achieve a high speed readout for multichannel detectors, like silicon strip detectors or MSGCs. The architecture is an alternative to existing designs with raw data pipelines as are commonly used in particle physics applications. The chip receives 128 digital input signals from an analog front end chip at a rate of up to 80 MHz. The hit pattern is sparsified in real time and only the addresses and interaction times of hits are stored temporarily in FIFOs. Multiple hits per event are possible. A trigger selects interesting events for readout. All other hits are automatically discarded. Untriggered readout at high rates is also possible. The occupied chip area depends on the average data rate which can be very small in many applications. Very compact designs with up to ten times less first level storage can therefore be realized.

  17. Contribution of Visual Information about Ball Trajectory to Baseball Hitting Accuracy.

    Full Text Available The contribution of visual information about a pitched ball to the accuracy of baseball-bat contact may vary depending on the part of trajectory seen. The purpose of the present study was to examine the relationship between hitting accuracy and the segment of the trajectory of the flying ball that can be seen by the batter. Ten college baseball field players participated in the study. The systematic error and standardized variability of ball-bat contact on the bat coordinate system and pitcher-to-catcher direction when hitting a ball launched from a pitching machine were measured with or without visual occlusion and analyzed using analysis of variance. The visual occlusion timing included occlusion from 150 milliseconds (ms after the ball release (R+150, occlusion from 150 ms before the expected arrival of the launched ball at the home plate (A-150, and a condition with no occlusion (NO. Twelve trials in each condition were performed using two ball speeds (31.9 m·s-1 and 40.3 m·s-1. Visual occlusion did not affect the mean location of ball-bat contact in the bat's long axis, short axis, and pitcher-to-catcher directions. Although the magnitude of standardized variability was significantly smaller in the bat's short axis direction than in the bat's long axis and pitcher-to-catcher directions (p < 0.001, additional visible time from the R+150 condition to the A-150 and NO conditions resulted in a further decrease in standardized variability only in the bat's short axis direction (p < 0.05. The results suggested that there is directional specificity in the magnitude of standardized variability with different visible time. The present study also confirmed the limitation to visual information is the later part of the ball trajectory for improving hitting accuracy, which is likely due to visuo-motor delay.

    A simple study of the relationship between the QBO and the number of hurricanes in the Atlantic, both in the Basin and hitting the U.S. coastline, demonstrates that the QBO is not a particularly useful index to help predict hurricane numbers on five-year time scales. It is shown that there is very little difference between the number of hurricanes following easterly winds in the equatorial stratosphere and the number that follow westerly winds. Given this it is reasonable one would make better predictions just using the mean number of hurricanes in lieu of using the QBO and this is also simply demonstrated here.

    A screening of structurally different steroid hormone synthesis inhibitors was performed in order to find a starting point for the development of a new inhibitor of the bifunctional steroidogenic enzyme CYP17A1. Emphasis was placed on determination of selectivity between the two catalytic steps, namely 17α-hydroxylase and C(17,20)-lyase. For that purpose a new inhibition assay has been developed. Hits identified within this novel assay demonstrated selective inhibition of CYP17A1 lyase activity, and thus mark the basis for the development of selective C(17,20)-lyase inhibitors for the treatment of prostate cancer.

  9. Middle-Out Approaches to Reform of University Teaching and Learning: Champions striding between the top-down and bottom-up approaches

    Directory of Open Access Journals (Sweden)

    2005-03-01

    Full Text Available In recent years, Australian universities have been driven by a diversity of external forces, including funding cuts, massification of higher education, and changing student demographics, to reform their relationship with students and improve teaching and learning, particularly for those studying off-campus or part-time. Many universities have responded to these forces either through formal strategic plans developed top-down by executive staff or through organic developments arising from staff in a bottom-up approach. By contrast, much of Murdoch University’s response has been led by a small number of staff who have middle management responsibilities and who have championed the reform of key university functions, largely in spite of current policy or accepted practice. This paper argues that the ‘middle-out’ strategy has both a basis in change management theory and practice, and a number of strengths, including low risk, low cost, and high sustainability. Three linked examples of middle-out change management in teaching and learning at Murdoch University are described and the outcomes analyzed to demonstrate the benefits and pitfalls of this approach.

    We present the first results of the High cadence Transient Survey (HiTS), a survey whose objective is to detect and follow up optical transients with characteristic timescales from hours to days, especially the earliest hours of supernova (SN) explosions. HiTS uses the Dark Energy Camera (DECam) and a custom made pipeline for image subtraction, candidate filtering and candidate visualization, which runs in real-time to be able to react rapidly to the new transients. We discuss the survey design, the technical challenges associated with the real-time analysis of these large volumes of data and our first results. In our 2013, 2014 and 2015 campaigns we have detected more than 120 young SN candidates, but we did not find a clear signature from the short-lived SN shock breakouts (SBOs) originating after the core collapse of red supergiant stars, which was the initial science aim of this survey. Using the empirical distribution of limiting-magnitudes from our observational campaigns we measured the expected recove...

  12. An Analytic Model for the Success Rate of a Robotic Actuator System in Hitting Random Targets.

    Autonomous robotic systems are increasingly being used in a wide range of applications such as precision agriculture, medicine, and the military. These systems have common features which often includes an action by an "actuator" interacting with a target. While simulations and measurements exist for the success rate of hitting targets by some systems, there is a dearth of analytic models which can give insight into, and guidance on optimization, of new robotic systems. The present paper develops a simple model for estimation of the success rate for hitting random targets from a moving platform. The model has two main dimensionless parameters: the ratio of actuator spacing to target diameter; and the ratio of platform distance moved (between actuator "firings") to the target diameter. It is found that regions of parameter space having specified high success are described by simple equations, providing guidance on design. The role of a "cost function" is introduced which, when minimized, provides optimization of design, operating, and risk mitigation costs.

    Full Text Available OBJECTIVE: To clarify the regulation of protein kinase C on glucose-mediated insulin secretion. MAIN OUTCOME MEASURES: We examined the effect of protein kinase C on the cytosolic free Ca(2+ concentration ([Ca(2+]i and the activity of Ca(2+-activated K(+ channels (K(Ca-channel in the insulinoma cell line, HIT-T15. RESULTS: Glucose at a concentration of 10 mmol/L increased the secretion of insulin. This increase was partly inhibited by 1 nmol/L staurosporine, a protein kinase C inhibitor. Staurosporine (1 nmol/L also attenuated the glucose-induced elevations in [Ca(2+]i. On the contrary, glibenclamide (100 nmol/L specifically blocked ATP-sensitive K(+ channels, and increased both [Ca(2+]i and insulin secretion, but staurosporine had no effect on them. Patch clamp studies showed that 10 mmol/L glucose almost completely blocked K(Ca channel activity, an effect that was reversed by 1 nmol/L staurosporine. Phorbol 12-myristate 13-acetate (1 mmol/L, a protein kinase C activator, also decreased K(Ca channel activity. CONCLUSIONS: These results indicate that the activation of protein kinase C is involved in the glucose-induced release of insulin by modulating K(+ channel function in HIT-T15 cells.

    Most previous research on golf swing mechanics has focused on the driver club. The aim of this study was to identify the kinematic factors that contribute to greater hitting distance when using the 5 iron club. Three-dimensional marker coordinate data were collected (250 Hz) to calculate joint kinematics at eight key swing events, while a swing analyser measured club swing and ball launch characteristics. Thirty male participants were assigned to one of two groups, based on their ball launch speed (high: 52.9 ± 2.1 m · s(-1); low: 39.9 ± 5.2 m · s(-1)). Statistical analyses were used to identify variables that differed significantly between the two groups. Results showed significant differences were evident between the two groups for club face impact point and a number of joint angles and angular velocities, with greater shoulder flexion and less left shoulder internal rotation in the backswing, greater extension angular velocity in both shoulders at early downswing, greater left shoulder adduction angular velocity at ball contact, greater hip joint movement and X Factor angle during the downswing, and greater left elbow extension early in the downswing appearing to contribute to greater hitting distance with the 5 iron club.

    Quantifying external workload is fundamental to training prescription in sport. In tennis, global positioning data are imprecise and fail to capture hitting loads. The current gold standard (manual notation) is time intensive and often not possible given players' heavy travel schedules. The aim of this study was to develop an automated stroke classification system to help quantify hitting load in tennis. 18 athletes wore an inertial measurement unit (IMU) on their wrist during 66 video-recorded training sessions. Video footage was manually notated such that known shot type (serve, rally forehand, slice forehand, forehand volley, rally backhand, slice backhand, backhand volley, smash or false positive) was associated with the corresponding IMU data for 28,582 shots. Six types of machine learning models were then constructed to classify true shot type from the IMU signals. Across 10-fold cross-validation, a cubic kernel support vector machine classified binned shots (overhead, forehand or backhand) with an accuracy of 97.4%. A second cubic kernel support vector machine achieved 93.2% accuracy when classifying all 9 shot types. With a view to monitoring external load, the combination of miniature inertial sensors and machine learning can offer a practical and automated method for quantifying shot counts and for discriminating shot types in elite tennis players.

    Discharges in the HIT-II spherical torus device [Redd et al., Phys. Plasmas 9, 2006 (2002)] can be driven by either Ohmic or Coaxial Helicity Injection (CHI) current drive. A new CHI operating regime has been explored, with toroidal plasma currents of up to 350 kA, I_p/I_TF ratios of up to 1.2, and internal probing data which may demonstrate the formation of a closed-flux core. The key to acheiving these results is the magnetic field shear in the CHI injector region, with a minimum shear necessary for current build-up. Ohmic plasma performance has also improved, with peak currents up to 300 kA, with and without transient CHI startup. The CHI startup technique [Raman et al., Phys. Plasmas 11, 2565 (2004)] provides more robust discharges, with a wider operating space and more efficient use of the transformer Volt-seconds, than unassisted Ohmic. Finally, CHI can be used to enhance an Ohmic plasma current without significantly degrading the quality of the discharge. Results will be presented for each HIT--II operating regime, including empirical performance scalings and applicable parametric operating spaces.

    The wwLigCSRre web server performs ligand-based screening using a 3D molecular similarity engine. Its aim is to provide an online versatile facility to assist the exploration of the chemical similarity of families of compounds, or to propose some scaffold hopping from a query compound. The service allows the user to screen several chemically diversified focused banks, such as Kinase-, CNS-, GPCR-, Ion-channel-, Antibacterial-, Anticancer- and Analgesic-focused libraries. The server also provides the possibility to screen the DrugBank and DSSTOX/Carcinogenic compounds databases. User banks can also been downloaded. The 3D similarity search combines both geometrical (3D) and physicochemical information. Starting from one 3D ligand molecule as query, the screening of such databases can lead to unraveled compound scaffold as hits or help to optimize previously identified hit molecules in a SAR (Structure activity relationship) project. wwLigCSRre can be accessed at http://bioserv.rpbs.univ-paris-diderot.fr/wwLigCSRre.html.

  19. Preparation of Vanadium Dioxide Films for Protection from High-energy Laser Hits

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    Vanadium dioxide(VO2)thin films are used for protection from high-energy laser hits due to their semiconductor-to-metal phase transition experienced during heating at temperature of approximately 68℃,which followed by a abrupt change of optical behavior, namely from transparent semiconductor state below 68℃ to highly reflective metallic state beyond 68℃.The preparation and properties of the films are described as well as the primary principle of the device for protection from high energy laser hits. An ion-beam-sputtering system is used to deposit VO2 thin films.The technique is reactive ion beam sputtering of vanadium at temperature of 200℃ on Si, Ge and Si3N4 substrates in a well controlled atmosphere of argon with a partial pressure of O2, followed by a post annealing at 400-550℃ with argon gas.The optical transmittance changes from 60% to 4% are obtained within the temperature range from 50℃ to 70℃. X-ray diffraction (XRD) shows that the films are of single-phase VO2.

  20. Hitting times, commute distances and the spectral gap for large random geometric graphs

    von Luxburg, Ulrike; Hein, Matthias

    2010-01-01

    The commute distance between two vertices in a graph is the expected time it takes a random walk to travel from the first to the second vertex and back. According to folklore opinion, it has the property that vertices in the same cluster of the graph are close to each other while vertices in different clusters are far from each other. We study the behavior of the commute distance and hitting times on random geometric graphs ($\\epsilon$-graphs, $k$-nearest neighbor graphs and Gaussian similarity graphs). It turns out that as the size of the graph increases, the suitably rescaled hitting times and commute distances can be approximated by extremely simple expressions. However, these expressions no longer take into account the cluster structure of the graph, which leads to a completely meaningless distance function. Consequently, the use of the commute distance for machine learning purposes is discouraged for large graphs and in high dimensions. Our paper also makes several important technical contributions such ...

  1. Hubs and authorities in the world trade network using a weighted HITS algorithm.

    2014-01-01

    We investigate the economic hubs and authorities of the world trade network (WTN) from 1992 to 2012, an era of rapid economic globalization. Using a well-defined weighted hyperlink-induced topic search (HITS) algorithm, we can calculate the values of the weighted HITS hub and authority for each country in a conjugate way. In the context of the WTN, authority values are large for countries with significant imports from large hub countries, and hub values are large for countries with significant exports to high-authority countries. The United States was the largest economic authority in the WTN from 1992 to 2012. The authority value of the United States has declined since 2001, and China has now become the largest hub in the WTN. At the same time, China's authority value has grown as China is transforming itself from the "factory of the world" to the "market of the world." European countries show a tendency to trade mostly within the European Union, which has decreased Europe's hub and authority values. Japan's authority value has increased slowly, while its hub value has declined. These changes are consistent with Japan's transition from being an export-driven economy in its high economic growth era in the latter half of the twentieth century to being a more mature, economically balanced nation.

    2016-01-01

    We present analytical results for the distribution of first hitting times of random walkers on Erd\\H{o}s-R\\'enyi networks. Starting from a random initial node, a random walker hops randomly between adjacent nodes on the network until it hits a node which it has already visited before. At this point, the path is terminated. The path length $d$, pursued by the random walker from the initial node up to its termination is called the first hitting time or the first intersection length. Using recursion equations, we obtain analytical results for the tail distribution of the path lengths, $P(d>\\ell)$. The results are found to be in excellent agreement with simulations. It turns out that the distribution $P(d>\\ell)$ follows a product of an exponential distribution and a Rayleigh distribution. We also obtain expressions for the mean, median and standard deviation of this distribution in terms of the network size and its mean degree. It is found that the first hitting time is much shorter than the last hitting time of ...

  4. Comparison of allocation algorithms for unambiguous registration of hits in presence of charge sharing in pixel detectors

    Charge sharing is the fractional collection of the charge cloud generated in a detector by two or more adjacent pixels. It may lead to excessive or inefficient registration of hits comparing to the number of impinging photons depending on how discrimination thresholds are set in typical photon counting pixel detector. The problems are particularly exposed for fine pixel sizes and/or for thick planar detectors. Presence of charge sharing is one of the limiting factors that discourages decreasing sizes of pixels in photon counting mode X-ray radiation imaging systems. Currently, a few different approaches tackling with the charge sharing problem exist (e.g. Medipix3RX, PIXIE, miniVIPIC or PIX45). The general idea is, first, to reconstruct the entire signal from adjacent pixels and, secondly, to allocate the hit to a single pixel. This paper focuses on the latter part of the process, i.e. on a comparison of how different hit allocation algorithms affect the spatial accuracy and false registration vs. missed hit probability. Different hit allocation algorithms were simulated, including standard photon counting (no full signal reconstruction) and the C8P1 algorithm. Also, a novel approach, based on a detection of patterns, with significantly limited analog signal processing, was proposed and characterized.

    On May 12, 2008, a magnitude 8.0 earthquake hit Wenchuan County, Sichuan Province resulted in great loss of life and properties. Besides, abundant landslides and slope failures were triggered in the most seriously hit areas and caused disastrous damages to infrastructures and public facilities. Moreover, abundant unstable slopes caused by the quake have the potential to cause damages for a considerable long period of time. The variety of these slopes and the corresponding treatments are connected with the topographical and geological conditions of the sites. It is decided to document and identify some of these major slope instabilities caused by the earthquake and their treatments. The paper shows the condition of a road in Dujiangyan through in situ explorations. The case history showed significant implications to the reconstruction of the quake-hit regions and future disaster prevention and management works.

    School officials across the country have recognized that many of their students live in homes where domestic violence occurs. As a result, several elementary schools have implemented education-based programs focused on this issue. The current study evaluates the efficacy of the "I Wish the Hitting Would Stop . . . " program that was presented to elementary school children in two school districts in the Midwest. This study examines the level of knowledge retention by students who participated in the "I Wish the Hitting Would Stop . . . " program during the 2010-2011 and 2011-2012 academic years. Fourth- and fifth-grade students responded to open-ended questions regarding their understanding of domestic violence and their retention of the concepts presented in the "I Wish the Hitting Would Stop . . . " curriculum. While the results suggest that students retain the information presented in the program, there also appears to be a gender difference in knowledge retention.

    The Lund Nuclear Microprobe (LNM) has been adapted to be used as a Single Ion Hit Facility (SIHF) for proton cell irradiation experiments at low dose. In order to test the capabilities of the system, Ni dot arrays and artificial cells have been fabricated with the photopolymer SU-8 and common lithographic techniques. The primary purpose of the Ni dot arrays was to determine the targeting accuracy of the beam in vacuum and in air. Additionally, this sample was employed to evaluate the system performance during cell target irradiation experiments. The Ni dot arrays were also used for beam characterization. The artificial cells were originally fabricated to test the software for cell recognition and localization, developed and implemented at the LNM. However, this sample became very functional to make small adjustments at the irradiation chamber for cell irradiation experiments. A description of the samples, fabrication procedure and applications are presented in this paper.

    2003-04-01

    Full Text Available Most studies of the EU and its member-states are concerned with how processes of European integration hit the member-states. This article shifts emphasis from this top-down towards a bottom-up approach and asks whether and how differences in domestic institutional constellations shape the representational roles of member-state officials when carrying out representational tasks in the EU Council of Ministers. The key objective of this study is to build a conceptual framework that renders intelligible the domestic origins of representational roles among domestic officials attending EU institutions. For this we draw on theories of political representation, institutional theories and the literature on how member-states adapt to European integration. Our primary argument is that role perceptions are considerably conditioned by actors domestic institutional embeddedness. This argument is substantiated by an illustrative comparison of Belgian and Swedish officials attending working groups within the Council of Ministers.

    2007-10-01

    A new type of Gd-loaded plastic neutron detector with a broad dynamic range (from thermal to MeV range) and multi-hit capability has been designed and subjected to series of tests. The device consists of a stack of alternating plastic scintillator (Saint Gobain BC-408) slabs and thin radiator films (PDMS -- SYLGARD 184) loaded with 0.5% of Gd per weight, viewed by a photomultiplier tube. The scintillator functions as neutron moderator, provides a prompt integrated neutron energy signal, and detects delayed n capture by Gd nuclei via associated capture γ-rays. The design, Monte Carlo simulations carried out with an extended code DENIS(E), as well as first measurements with the detector will be discussed.

    Drift chambers have been installed for luminosity measurements in intersection 5 of the SPS accelerator working in panti p colliding mode. The required electronics is described. The system is able to process up to 16 hits per wire with a double pulse resolution of 40 ns; drift time and current division, with 1.25 ns and 1.6% resolution respectively, are recorded. Transconductance preamplifiers and discriminators are directly mounted on the chamber; 160 m of twisted-apir cable bring the signals to the digitizer unit. Coarse time is measured using RAM techniques, while fine time is obtained by means of a microstrip delay associated with a 100 K ECL priority encoder. Current division used a single 50 MHz Flash ADC which alows 26 dB dynamic range with 6 bit resolution. First operational results are reported.

    The convex set of quantum states of a composite K × K system with positive partial transpose is analysed. A version of the hit and run algorithm is used to generate a sequence of random points covering this set uniformly and an estimation for the convergence speed of the algorithm is derived. For K≥slant 3 this algorithm works faster than sampling over the entire set of states and verifying whether the partial transpose is positive. The level density of the PPT states is shown to differ from the Marchenko-Pastur distribution, supported in [0, 4] and corresponding asymptotically to the entire set of quantum states. Based on the shifted semi-circle law, describing asymptotic level density of partially transposed states, and on the level density for the Gaussian unitary ensemble with constraints for the spectrum we find an explicit form of the probability distribution supported in [0, 3], which describes well the level density obtained numerically for PPT states.

    2013-09-01

    Incubation time is a key epidemiologic descriptor of an infectious disease. In the case of HIV infection this is a random variable and is probably the longest one. The probability distribution of incubation time is the major determinant of the relation between the incidences of HIV infection and its manifestation to Aids. This is also one of the key factors used for accurate estimation of AIDS incidence in a region. The present article i) briefly reviews the work done, points out uncertainties in estimation of AIDS onset time and stresses the need for its precise estimation, ii) highlights some of the modelling features of onset distribution including immune failure mechanism, and iii) proposes a 'Double Hit' model for the distribution of time to AIDS onset in the cases of (a) independent and (b) dependent time variables of the two markers and examined the applicability of a few standard probability models.

    DNA-encoded chemical libraries (DECLs) are large collections of compounds linked to DNA fragments, serving as amplifiable barcodes, which can be screened on target proteins of interest. In typical DECL selections, preferential binders are identified by high-throughput DNA sequencing, by comparing their frequency before and after the affinity capture step. Hits identified in this procedure need to be confirmed, by resynthesis and by performing affinity measurements. In this article we present new methods based on hybridization of oligonucleotide conjugates with fluorescently labeled complementary oligonucleotides; these facilitate the determination of affinity constants and kinetic dissociation constants. The experimental procedures were demonstrated with acetazolamide, a binder to carbonic anhydrase IX with a dissociation constant in the nanomolar range. The detection of binding events was compatible not only with fluorescence polarization methodologies, but also with Alphascreen technology and with microscale thermophoresis.

    Full Text Available B-cell lymphomas with concurrent IGH-BCL2 and MYC rearrangements, also known as “double hit” lymphomas (DHL, are rare neoplasms characterized by highly aggressive clinical behavior, complex karyotypes, and a spectrum of pathological features overlapping with Burkitt lymphoma (BL and diffuse large B-cell lymphoma (DLBCL. Primary renal lymphoma (PRL by definition is a renal lymphoma without evidence of systemic involvement. PRL is extremely rare with less than 100 cases of both Hodgkin disease and non-Hodgkin lymphoma reported in literature. Double hit lymphomas have extremely poor prognosis, and high resistance to intensive chemotherapy, including high-dose chemotherapy. We describe a very rare case of DHL arising in kidney as PRL in whom concurrent IGH-BCL2 and MYC rearrangements were detected. [J Interdiscipl Histopathol 2013; 1(2.000: 93-97

    B cells lymphoma is one of the most challenging extra-hepatic manifestations of hepatitis C virus (HCV). Recently, a new kind of B-cell lymphoma, named double-hit B (DHL), was characterized with an aggressive clinical course whereas a potential association with HCV was not investigated. The new antiviral direct agents (DAAs) against HCV are effective and curative in the majority of HCV infections. We report the first case, to our knowledge, of DHL and HCV-infection successfully treated by new DAAs. According to our experience, a DHL must be suspected in case of HCV-related lymphoma, and an early diagnosis could direct towards a different hematological management because a worse prognosis might be expected. A possible effect of DAAs on DHL regression should be investigated, but eradicating HCV would avoid life-threatening reactivation of viral hepatitis during pharmacological immunosuppression in onco-haematological diseases.

    The Heidelberg Ion Therapy Center (HIT) started clinical operation in November 2009. In this report we present the first 80 patients treated with proton and carbon ion radiotherapy and describe patient selection, treatment planning and daily treatment for different indications. Patients and methods. Between November 15, 2009 and April 15, 2010, 80 patients were treated at the Heidelberg Ion Therapy Center (HIT) with carbon ion and proton radiotherapy. Main treated indications consisted of skull base chordoma (n = 9) and chondrosarcoma (n = 18), malignant salivary gland tumors (n=29), chordomas of the sacrum (n = 5), low grade glioma (n=3), primary and recurrent malignant astrocytoma and glioblastoma (n=7) and well as osteosarcoma (n = 3). Of these patients, four pediatric patients aged under 18 years were treated. Results. All patients were treated using the intensity-modulated rasterscanning technique. Seventy-six patients were treated with carbon ions (95%), and four patients were treated with protons. In all patients x-ray imaging was performed prior to each fraction. Treatment concepts were based on the initial experiences with carbon ion therapy at the Gesellschaft fuer Schwerionenforschung (GSI) including carbon-only treatments and carbon-boost treatments with photon-IMRT. The average time per fraction in the treatment room per patient was 29 minutes; for irradiation only, the mean time including all patients was 16 minutes. Position verification was performed prior to every treatment fraction with orthogonal x-ray imaging. Conclusion. Particle therapy could be included successfully into the clinical routine at the Dept. of Radiation Oncology in Heidelberg. Numerous clinical trials will subsequently be initiated to precisely define the role of proton and carbon ion radiotherapy in radiation oncology.

    Significance testing one SNP at a time has proven useful for identifying genomic regions that harbor variants affecting human disease. But after an initial genome scan has identified a "hit region" of association, single-locus approaches can falter. Local linkage disequilibrium (LD) can make both the number of underlying true signals and their identities ambiguous. Simultaneous modeling of multiple loci should help. However, it is typically applied ad hoc: conditioning on the top SNPs, with limited exploration of the model space and no assessment of how sensitive model choice was to sampling variability. Formal alternatives exist but are seldom used. Bayesian variable selection is coherent but requires specifying a full joint model, including priors on parameters and the model space. Penalized regression methods (e.g., LASSO) appear promising but require calibration, and, once calibrated, lead to a choice of SNPs that can be misleadingly decisive. We present a general method for characterizing uncertainty in model choice that is tailored to reprioritizing SNPs within a hit region under strong LD. Our method, LASSO local automatic regularization resample model averaging (LLARRMA), combines LASSO shrinkage with resample model averaging and multiple imputation, estimating for each SNP the probability that it would be included in a multi-SNP model in alternative realizations of the data. We apply LLARRMA to simulations based on case-control genome-wide association studies data, and find that when there are several causal loci and strong LD, LLARRMA identifies a set of candidates that is enriched for true signals relative to single locus analysis and to the recently proposed method of Stability Selection.

    This phase 1b study evaluated the safety and efficacy of 3 dose levels of carfilzomib when provided with fixed dose oral cyclophosphamide and dexamethasone (KCyd) in patients with newly diagnosed multiple myeloma (MM). CHAMPION-2 was a multicenter single-arm study. Patients with newly diagnosed secretory MM were enrolled and received KCyd treatment for up to 8 cycles. A 3 + 3 dose escalation scheme was used to evaluate twice-weekly carfilzomib at 36, 45, and 56 mg/m(2) dose levels, followed by a dose expansion. No dose-limiting toxicities were observed in any of the dose evaluation cohorts. The KCyd regimen that included the maximum planned carfilzomib dose of 56 mg/m(2) twice weekly was brought forward into dose expansion. A total of 16 patients were treated at this dose level. At 56 mg/m(2) the overall response rate was 87.5% (95% confidence interval, 61.7-98.4), and the median time to response of 14 patients whose disease responded to therapy was 1 month. At this dose level, common adverse events of grade 3 or higher were anemia (25.0%), neutropenia (18.8%), acute kidney injury (12.5%), and decreased white blood cell count (12.5%). Ten of 16 patients who received carfilzomib at 56 mg/m(2) completed all 8 cycles, 5 patients discontinued study therapy before cycle 8 as a result of adverse events, and 1 patient discontinued therapy as a result of progressive disease. Carfilzomib in combination with cyclophosphamide and dexamethasone is effective and has manageable toxicity for patients with newly diagnosed MM. Copyright © 2017 The Authors.
