SIDANE: Towards the Automatic Analysis of Football Tactics and Actions

In recent years technology has been used as an engine to improve the performance of the players and the preparation offered by trainers in a great variety of sports. In some of them, such as football, technology has contributed enormously to improving monitoring of players so as to assess their performance and to prepare tactics and strategies that are so essential nowadays for making the difference, before facing a match. In this paper we present SIDANE, an expert system capable of detecting important situations in football, from a tactics point of view and assessing if the players involved took a good decision from the point of view of the trainer. The SIDANE reasoning engine uses Fuzzy Logic with the aim of tackling uncertainty and facilitating the definition of rules close to the way in which the trainer communicates with his or her players. In this way the distance between expert and machine is greatly narrowed. The results yielded show how powerful SIDANE is as a starting point for the automatic analysis of important situations in team sports.
Properties of the Internal Clock a

Evidence has been cited for the following properties of the parts of the psychological process used for timing intervals: The pacemaker has a mean rate that can be varied by drugs, diet, and stress. The switch has a latency to operate and it can be operated in various modes, such as run, stop, and reset. The accumulator times up, in absolute, arithmetic units. Working memory can be reset on command or, after lesions have been created in the fimbria fornix, when there is a gap in a signal. The transformation from the accumulator to reference memory is done with a multiplicative constant that is affected by drugs, lesions, and individual differences. The comparator uses a ratio between the value in the accumulator (or working memory) and reference memory. Finally, there must be multiple switch-accumulator modules to handle simultaneous temporal processing; and the psychological timing process may be used on some occasions and not on others.
Regulation of B Cell Linker Protein Transcription by PU.1 and Spi-B in Murine B Cell Acute Lymphoblastic Leukemia

B cell acute lymphoblastic leukemia (B-ALL) is frequently associated with mutations or chromosomal translocations of genes encoding transcription factors. Conditional deletion of genes encoding the E26-transformation–specific transcription factors, PU.1 and Spi-B, in B cells (ΔPB mice) leads to B-ALL in mice at 100% incidence rate and with a median survival of 21 wk. We hypothesized that PU.1 and Spi-B may redundantly activate transcription of genes encoding tumor suppressors in the B cell lineage. Characterization of aging ΔPB mice showed that leukemia cells expressing IL-7R were found in enlarged thymuses. IL-7R–expressing B-ALL cells grew in culture in response to IL-7 and could be maintained as cell lines. Cultured ΔPB cells expressed reduced levels of B cell linker protein (BLNK), a known tumor suppressor gene, compared with controls. The Blnk promoter contained a predicted PU.1 and/or Spi-B binding site that was required for promoter activity and occupied by PU.1 and/or Spi-B as determined by chromatin immunoprecipitation. Restoration of BLNK expression in cultured ΔPB cells opposed IL-7–dependent proliferation and induced early apoptosis. We conclude that the tumor suppressor BLNK is a target of transcriptional activation by PU.1 and Spi-B in the B cell lineage.

It gives an evaluation method for E-commerce in order to help researches and managers to determine the opportunities of better selection of e-commerce website based on parameters for future. Outlook, Operations and Services are the three broader categories desired by business professionals at the time of selection of best e-commerce website among all the available alternatives. The evaluation of parameters is done by using AHP and the ranking of parameters may help the business professionals to make best decision regarding design and operations of e-commerce websites.
Do Stock Markets Comove in Emerging Economies

Great Recession has brought the need to model and assess the financial markets with unconventional approaches. The nature of consumer behavior in financial markets has become crucial as real and financial sector comoving overtime was a dream of no rationality. The union of consumers looking for higher wealth and speculative stock market participants was not a sustainable case. But, what happened to the consumers/investors in emerging economies? This chapter assesses the behavior of emerging stock markets during the turmoil using weekly data for Brazil, China, India, Indonesia, Russia, South Africa and Turkey with US as the benchmark for January 2003–March 2014. Two unconventional methods are used for checking asymmetric contagion; the wavelet comovement and frequency domain causality. The findings show that markets with rather high concentration of foreign investors are highly affected but consumers were not due to smaller participation. The asymmetric contagion argument is verified for some emerging markets as consumers/investors suffered as much as any other market participant.
Immunological responses and protective immunity against tuberculosis conferred by vaccination of Balb/C mice with the attenuated Mycobacterium tuberculosis (phoP) SO2 strain

The Mycobacterium tuberculosis phoP mutant strain SO2 has been shown previously to be more attenuated than Mycobacterium bovis bacillus Calmette–Guérin (BCG) and confers protective immunity against tuberculosis in mice and guinea pig models. In this study we have investigated the survival and immunological responses of Balb/c mice infected with the M. tuberculosis SO2 strain. All Balb/C mice survived intratracheal infection with M. tuberculosis SO2 strain under conditions where all the mice infected with the parental M. tuberculosis MT103 had died after 9 weeks. Infection of Balb/c mice with M. tuberculosis SO2 was associated with comparatively lower levels of interferon (IFN)‐γ, interleukin (IL)‐4 and tumour necrosis factor (TNF)‐α and higher levels of inducible nitric oxide synthase (iNOS) during the late stage of infection, when compared with M. tuberculosis MT103 infection. The delayed‐type hypersensitivity (DTH) response against M. tuberculosis culture filtrates was similar in mice infected with either the M. tuberculosis phoP SO2 strain or M. tuberculosis MT103. The protective efficacy of M. tuberculosis SO2 was compared with M. bovis BCG when delivered subcutaneously to groups of Balb/C mice. Following intratracheal challenge with M. tuberculosis H37Rv, protection was generated by 60 days post‐challenge in mice vaccinated with either vaccine. At day 120 post‐challenge the levels of protection were still significantly greater when compared with the non‐vaccinated control group. The levels of protection conferred by vaccination with M. tuberculosis SO2 or with M. bovis BCG were similar, as measured by granuloma coalescence and pneumonia in addition to growth reduction of M. tuberculosis H37Rv.
Nocturnal excretion of a urinary melatonin metabolite among electric utility workers.

OBJECTIVES The effects of 60-Hz magnetic field and ambient light exposures on the pineal hormone melatonin were studied among electric utility workers. METHODS Personal exposure was measured at 15-second intervals over 3 consecutive 24-hour periods. Exposure metrics based on magnetic field intensity, intermittence, or temporal stability were calculated for periods of work, home, and sleep. A rate-of-change metric (RCM) was used to estimate intermittence, and the standardized RCM (RCMS = RCM/standard deviation) was used to evaluate temporal stability. The effects of magnetic field exposure on total overnight 6-hydroxymelatonin sulfate (6-OHMS) excretion and creatinine-adjusted nocturnal 6-OHMS (6-OHMS/cr) concentration were analyzed with adjustment for age, month, and light exposure. RESULTS Magnetic field intensity, intermittence, or cumulative exposure had little influence on nocturnal 6-OHMS excretion. Residential RCMS magnetic field exposures were associated with lower nocturnal 6-OHMS/cr concentrations. In multivariate statistical analyses, the interaction term for geometric mean and RCMS magnetic field exposures at home was associated with lower nocturnal 6-OHMS/cr and overnight 6-OHMS levels. Modest reductions in the mean 6-OHMS levels occurred after RCMS exposures during work. The greatest reductions occurred when RCMS exposures both at work and at home were combined; therefore the effects of temporally stable magnetic fields may be integrated over a large portion of the day. CONCLUSIONS Results from this study provide evidence that temporally stable magnetic field exposures are associated with reduced nocturnal 6-OHMS excretion in humans.
Flavobacterium johnsoniae SprA Is a Cell Surface Protein Involved in Gliding Motility

ABSTRACT Flavobacterium johnsoniae cells glide rapidly over surfaces by an unknown mechanism. Transposon-induced sprA mutants formed nonspreading colonies on agar, and the cells examined in wet mounts were deficient in attachment to surfaces and were almost completely nonmotile. Exposure of intact cells to proteinase K cleaved the 270-kDa SprA into several large peptides, suggesting that it is partially exposed on the cell surface.
1 Happiness and International Migration

In this paper, we consider the extent to which the aggregate happiness of a country affects the flow of people across its borders. We merge data from the World Values Survey, which produces happiness indices for 84 countries between 1981 and 2004, with three different migration datasets, and we find that happiness has a U-shaped relationship with emigration rates: emigration rates fall in happiness for relatively unhappy countries, but rise for relatively happy countries. The U-shaped relationship also holds for migrant flows into the U.S. When analyzing net migration rates, we find that the reverse relationship exists. Net migration is associated with an increase in happiness for relatively unhappy countries, but after a threshold level of happiness, net migration is associated with a decrease in happiness. Our findings are robust to various empirical specifications and datasets. JEL Codes: F22, I31, O15; International Migration, Happiness, Human Development/Migration ∗ Corresponding Author
Unscheduled Revisits to a Pediatric Emergency Department: Risk Factors for Children With Fever or Infection-Related Complaints

Objective: Unscheduled revisits (URVs) may serve as markers of quality of care and may be costly both in financial terms as well as in limitations they place on primary care. We performed this study to examine the association between characteristics easily obtainable during an emergency department (ED) visit and URV to identify a subpopulation of children who may warrant interventions to decrease URV. Methods: This is a case-control study of patients visiting an urban tertiary care pediatric ED for a fever or infectious disease-related complaint. Cases were defined as patients who had URVs that occurred within 72 hours of an initial ED visit. Control patients were selected by simple random sampling of an enumerated computerized list of all ED visits. Data on independent variables of interest were collected from a chart review and telephone interview with the patient's caregiver. Bivariate and multivariate analyses were performed to determine factors associated with URV. Results: Seventy-five percent of cases and controls participated in the study. Logistic regression analysis revealed 3 factors independently associated with URV for fever or infectious disease-related complaints in children. These included presence of chronic disease (adjusted odds ratio 1.75, 95% confidence interval 1.01-3.03), Medicaid insurance (adjusted odds ratio 1.86, 95% confidence interval 1.04-3.32) and acute triage category (adjusted odds ratio 1.83, 95% confidence interval 1.08-3.10). Conclusions: These factors may be used to identify children in the ED at greater risk for URV and may point to a need for improved discharge instructions and enhanced communication with primary care and systems to arrange follow-up. Results of this work may also identify at-risk populations for future qualitative research or intervention studies on URV to EDs.
PREVALENCE OF RETINAL DISEASES AND THEIR PATTERN IN TEHRAN: The Tehran Eye Study

Purpose: To determine the prevalence of retinal diseases and their pattern in Tehran through a population-based study. Methods: In 2002, through a stratified random cluster sampling, 6497 citizens representing a cross-section of the population of Tehran were selected from 160 clusters. Eligible people were recruited through a door-to-door household survey in selected clusters and transferred to a clinic for an extensive eye examination and interview. Results: The prevalence of retinal diseases was 8.56 per 100 (95% CI, 7.74–9.39). Acquired retinopathies (3.33 per 100) and peripheral retinal lesions (3.29 per 100) were the most common retinal diseases in our population. Cataract (12.47 per 100) was the major ocular comorbidity; high blood pressure (21.14 per 100) and diabetes mellitus (15.99 per 100) were the main systemic comorbidities among 415 patients with retinal diseases. The prevalence of low vision on the basis of best-corrected and presenting visual acuity was 0.63 and 2.87 per 100 in 415 patients with retinal disease. Two patients (0.48 per 100) were blind with corrected and presenting visual acuity. The prevalence of diabetic retinopathy in the studied population was 0.61 per 100 (95% CI, 0.39–0.82) and age-related macular degeneration was detected in 1.95 per 100 (95% CI, 1.55–2.34) of the population. Conclusions: These findings reveal a considerable prevalence of retinal diseases in the population. The prevalence might be underestimated due to the lack of fundus photography. The findings could be considered for case finding and planning treatment programs for specific retinal diseases.
Commutation strategies for single-chip dual-gate bidirectional IGBTs in matrix converters

This paper compares four different commutation strategies for a new monolithic dual-gate bidirectional IGBT (BD-IGBT) in matrix converters. A new variable-timing four-step commutation and an one-step commutation control strategies are proposed and compared with the conventional and the two-level four-step commutation methods reported previously. Operation modes and power losses of the BD-IGBT using these commutation strategies are analyzed with mixed-mode device/circuit simulation. The power loss and efficiency of a 13 kW three-phase to three-phase matrix converter are compared between the conventional combo switch and the new single-chip BD-IGBT implementations. It is found that the BD-IGBT, when using an optimal commutation strategy, offers significant advantages over the conventional IGBT/diode cell in terms of efficiency and cost.
Polyunsaturated phosphatidylcholine prevents stricture formation in a rat model of colitis.

BACKGROUND & AIMS Polyunsaturated phosphatidylcholine stimulates collagen breakdown in experimental models of liver cirrhosis. Bowel strictures are characterized by excess deposition of collagen in the intestinal wall. The aim of this study was to investigate the effect of polyunsaturated phosphatidylcholine in the prevention of bowel strictures. METHODS Colitis was induced by trinitrobenzenesulfonic acid. On day 21, the presence of strictures was assessed in control rats, rats with colitis, and phosphatidylcholine-fed (100 mg/day) rats with colitis. Furthermore, serum transforming growth factor beta1, collagen deposition, and collagenase activity in colonic tissue were measured in all groups. RESULTS None of the control rats but 12 of 16 rats with colitis developed colonic strictures. In contrast, only 2 of 15 phosphatidylcholine-fed rats with colitis showed strictures. Collagen content was much higher in rats with colitis than in phosphatidylcholine-fed rats with colitis and control rats. Phosphatidylcholine-fed rats showed significantly higher collagenase activity in colonic tissue than rats with colitis and control rats. In an ancillary study, free linoleic acid-fed rats showed no differences when compared with rats with colitis. Stimulation of transforming growth factor beta1 was similar in all rats with colitis. CONCLUSIONS Oral supplementation with polyunsaturated phosphatidylcholine prevents the accumulation of collagen in inflamed intestinal tissue and the formation of strictures. This effect is associated with an enhanced collagen catabolism.
The Impact of Ownership Structure on Financial Performance; A Comparison Study of Two Chinese Banks

Interest on the effect of ownership structure and financial performance has grown much, yet researchers have provided mixed results. This study aims at investigating the relationship between state-owned and joint venture type of ownership structures by testing whether or not there is a difference in their performance. The study used quantitative methods to find out if there is a significance difference in performance of two types of firms namely State Owned and Joint venture. The variables used were Return on asset, Return on Equity, Capital Adequacy, Non-performing Loans and Earnings per Share. Further, T-test was used to test the difference in performance of the two types of firms. The results have revealed that there is no significant difference in performance between the two types of ownership structure. Statistically, the performance of state-owned and joint ventures is the same. This means the efforts to radicalize the state-owned companies have paid off by eliminating the impact of ownership structure on financial performance of the firm.
Reelin and human nodular heterotopia

uation would seem appropriate. Distinction of subcategories no longer needs to rely on ‘‘astute observations and expert opinions’’ alone. Knowledge of the gene involved can have clinical and genetic counseling ramifications; 15% of patients with KCNQ2 mutations go on to develop seizures in later life (Scheffer et al., 2005), whereas patients with KCNQ3 and SCN2A mutations go on to normal development beyond infancy. The recent ILAE classification and terminology report (Berg et al., 2010) sets the stage for the inclusion of genetic information in diagnosis. Indeed, inclusion of laboratory data to improve diagnostic accuracy is compatible with the recent ILAE concept of recognizing ‘‘genetic epilepsies’’ as a distinct group encompassing many syndromes previously referred to as ‘‘idiopathic. ’’ Genetic testing is a legitimate adjunct to clinical diagnosis for the epilepsies, in the same way that electroencephalography (EEG) and imaging have been widely used. Genetic testing has been established in other areas of clinical genetics. The next step for the epilepsies is greater acceptance and more widespread application of genetic testing as an adjunct to syndrome description and clinical workup in situations in which knowledge of the defective gene can be useful for prognosis and patient management. The nomenclature style proposed for BFIE is sufficiently versatile for extension to similar situations in which causative genes have also been identified, such as for progressive myoclonus epilepsy (PME:SCARB2, PME:PRICKLE1) and genetic epilepsy with febrile seizures plus (GEFS:SCN1A, GEFS:SCN1B or GEFS:GABRG2).
Optimisation combinatoire pour la sélection de variables en régression en grande dimension : Application en génétique animale. (Combinatorial optimization for variable selection in high dimensional regression: Application in animal genetic)

Le developpement des technologies de sequencage et de genotypage haut-debit permet de mesurer, pour un individu, une grande quantite d'information genomique. L'objectif de ce travail est, dans le cadre de la selection genomique animale, de selectionner un sous-ensemble de marqueurs genetiques pertinents permettant de predire un caractere quantitatif, dans un contexte ou le nombre d'animaux genotypes est largement inferieur au nombre de marqueurs etudiees. Ce manuscrit presente un etat de l'art des methodes actuelles permettant de repondre a la problematique. Nous proposons ensuite de repondre a notre problematique de selection de variables en regression en grande dimension en combinant approches d'optimisation combinatoire et modeles statistiques. Nous commencons par parametrer experimentalement deux methodes d'optimisation combinatoire, la recherche locale iteree et l'algorithme genetique, combinees avec une regression li- neaire multiple et nous evaluons leur pertinence. Dans le contexte de la genomique animale les relations familiales entre animaux sont connues et peuvent constituer une information importante. Notre approche etant ﬂexible, nous proposons une adapta- tion permettant de prendre en consideration ces relations familiales via l'utilisation d'un modele mixte. Le probleme du sur-apprentissage etant particulierement present sur nos donnees du au desequilibre important entre le nombre de variables etudiees et le nombre d'animaux disponibles, nous proposons egalement une amelioration de notre approche permettant de diminuer ce sur-apprentissage. Les diﬀerentes approches proposees sont validees sur des donnees de la litterature ainsi que sur des donnees reelles de Genes Diﬀusion.
Assistive technology to promote occupation and reduce mouthing by three boys with fragile X syndrome

ABSTRACT Objectives: To extend the use of assistive technology (AT) for promoting a new adaptive response and to reduce hand mouthing, by three boys with fragile X syndrome. To monitor the effects of the intervention program on the positive mood. To carry out a three month follow-up phases. To conduct a social validation assessment involving 30 parents of children who presented multiple disabilities as raters. Methods: The study was implemented according to an ABAB experimental design, where A represented baseline phases (technology available but inactive) and B represented intervention phases (the technology ensured 7 s of positive stimulation). Results: All participants improved and consolidated their performance. Parents involved in the social validation assessment rated positively the use of such technology. Conclusion: AT-based program was useful, affordable, and effective for enhancing constructive engagement, self-determination, and for improving quality of life by children with fragile X syndrome and severe to profound developmental disabilities.
The Role of Influenza A Virus Hemagglutinin Residues 226 and 228 in Receptor Specificity and Host Range Restriction

ABSTRACT Influenza A viruses can be isolated from a variety of animals, but their range of hosts is restricted. For example, human influenza viruses do not replicate in duck intestine, the major replication site of avian viruses in ducks. Although amino acids at positions 226 and 228 of hemagglutinin (HA) of the H3 subtype are known to be important for this host range restriction, the contributions of specific amino acids at these positions to restriction were not known. Here, we address this issue by generating HAs with site-specific mutations of a human virus that contain different amino acid residues at these positions. We also let ducks select replication-competent viruses from a replication-incompetent virus containing a human virus HA by inoculating animals with 1010.5 50% egg infectious dose of the latter virus and identified a mutation in the HA. Our results showed that the Ser-to-Gly mutation at position 228, in addition to the Leu-to-Gln mutation at position 226 of the HA of the H3 subtype, is critical for human virus HA to support virus replication in duck intestine.
