Is there a difference by sex in simple reaction time and impulsivity in Junior Brazilian Judo Team athletes

Background & Study Aim: The simple reaction time and impulsivity are variables that contribute to the athlete’s performance in com‐ bat sports. However, little is known about the behaviour of these two variables in relation to elite athletes in judo. Thus, the aim of this study was to knowledge whether there was a difference in simple reaction time and impulsivity in athletes of the Junior Brazilian Judo Team from different sexes. Material and Methods: The mean and standard deviation by two groups of Junior Brazilian Judo Team in 2016 were compared: 17 male athletes (18.5 ±6.8 years); 17 female athletes (18.9 ±7.5 years). The reaction time (RT), time of movement (TM) and response time (Tres) were measured by the Reaction Test (RT/S1), present in the Vienna Test System SPORTS® (VTS). To measure the general impulsiveness and its dimensions (second-order factors: attentional, motor, non-planning) the Barratt Impulsiveness Scale (BIS-11) was used (scored in points). The statistical pro‐ cedures used were mean, standard deviation and the tests of Shapiro Wilk, the independent Student t-test and the effect size (p<0.05). Results: The result were: RT (males 271 ±41 ms, females 268 ±51 ms); TM (males 126 ±31 ms, females 134 ±41 ms); Tres (males 396 ±65 ms, females 401 ±75 ms); BIS-11 (points): impulsivity general (males 59 ±6, females 62 ±10); attentional (males 16 ±3, females 17 ±4); motor (males 19 ±3, females 18 ±4); non planning (males 25 ±3, females 26 ±4). Concerning sex comparison, no significant differences were verified for any variable. Conclusions: The simple reaction time and impulsiveness have similar values in comparison to sex between men and wom‐ en who were summoned to the national team. This indicating that this level of the yield of these two variables are quite homogeneous by sex, considering the high trainability of these athletes and the degree of require‐ ment of sports in which they train and compete.
Dynamic Tracking Human Mesenchymal Stem Cells Tropism following Smoke Inhalation Injury in NOD/SCID Mice

Multiple preclinical evidences have supported the potential value of mesenchymal stem cells (MSCs) for treatment of acute lung injury (ALI). However, few studies focus on the dynamic tropism of MSCs in animals with acute lung injury. In this study, we track systemically transplanted human bone marrow-derived mesenchymal stem cells (hBMSCs) in NOD/SCID mice with smoke inhalation injury (SII) through bioluminescence imaging (BLI). The results showed that hBMSCs systemically delivered into healthy NOD/SCID mouse initially reside in the lungs and then partially translocate to the abdomen after 24 h. Compared with the uninjured control group treated with hBMSCs, higher numbers of hBMSCs were found in the lungs of the SII NOD/SCID mice. In both the uninjured and SII mice, the BLI signals in the lungs steadily decreased over time and disappeared by 5 days after treatment. hBMSCs significantly attenuated lung injury, elevated the levels of KGF, decreased the levels of TNF-α in BALF, and inhibited inflammatory cell infiltration in the mice with SII. In conclusion, our findings demonstrated that more systemically infused hBMSCs localized to the lungs in mice with SII. hBMSC xenografts repaired smoke inhalation-induced lung injury in mice. This repair was maybe due to the effect of anti-inflammatory and secreting KGF of hMSCs but not associated with the differentiation of the hBMSCs into alveolar epithelial cells.
Phytochemical Screening and comparison of DPPH radical scavenging from different samples of coffee and Yerba Mate beverages

A phytochemical screening of commercial samples of roasted coffee, soluble coffee and yerba maté prepared as tereré and chimarrão consumed in South America was evaluated. All samples were subjected to a qualitative assay for phytochemical screening in order to detect classes of phenolic compounds, as well as FT-IR analysis of the dried crude extracts, Antioxidant potential was conducted with DPPH assay. The results were similar to each sort of samples according to the presence of phenolic compounds classes, meanwhile the antioxidant potential percentage were varied.
Limited Liability and Rational Overinsurance: An Analysis of Dependence Structures

A main nding within the economic theory of insurance is that limited liability leads to a reduction in the demand for insurance coverage. In this paper we show that this result only holds, if the indemnity is monotonically increasing by the amount of loss. If this constraint is not fullled, limited liability will indeed cause a reduction in the demand for coverage for large losses in some cases, but, surprisingly, there is a tendency to overinsure small losses. We specify the conditions of such an extraordinary extension of insurance demand. Therefore, limited liability leads to a change in the structure of demand for insurance, but not necessarily to a reduction. Hence, our nding is partially
The Economics of Patents

Patents are perhaps the most important legal instruments for protecting intellectual property rights (IPRs). A patent confers to an inventor the sole right to exclude others from economically exploiting the innovation for a limited time (20 years from the date of filing). To be patentable, an innovation must be novel in the sense of not constituting part of the prior art or more generally of not being already in the public domain. A patentable innovation also must involve an inventive step, meaning that it must be non-obvious to a person with ordinary skills in the particular field of application. The innovation also must be useful to be patentable; that is, it must permit the solution of a particular problem in at least one application. A major element of a patent application is disclosure: the invention must be described in sufficient detail to enable those skilled in the particular field to practise it. The patent application also lays out specific claims as to the scope of the patent itself. The traditional statutory scope of patents, encompassing machines, industrial processes, composition of matter and articles of manufacture, excluded important kinds of scientific discoveries such as laws of nature, natural phenomena and abstract ideas. However, recent developments in the use of patents for computer software, information technology and biotechnology innovations are challenging a reductive interpretation of such exclusions. See Merges (1997) for further details and a comprehensive treatment of US patent law. Given that private property is inherently associated with the freedom of choice that constitutes the cornerstone of market economies (Barzel, 1989), it may seem obvious that intangible assets associated 3
Male Fertility and Reduction in Semen Parameters: A Single Tertiary-Care Center Experience

Background. Infertility is both a clinical and a public problem, affecting the life of the couple, the healthcare services, and social environment. Standard semen analysis is the surrogate measure of male fertility in clinical practice. Objective. To provide information about the relationship between semen parameters and spontaneous conception. Methods. We evaluated retrospectively 453 pregnancies that occurred among 2935 infertile couples evaluated at an infertility clinic of a tertiary-care university hospital, between 2004 and 2009. Results. Normal semen analysis was present only in 158 patients; 295 subfertile patients showed alterations in at least one seminal parameter. A reduction in all seminal parameters was observed in 41 patients. Etiological causes of male infertility were identified in 314 patients. Conclusion. Our data highlights the possibility of a spontaneous conception with semen parameters below WHO reference values. Therefore, we support the importance of defining reference values on a population of fertile men. Finally, we analyzed the related ethical issues.
GEOMETRIC DEPENDENCY ANALYSIS

We investigate methods for estimating and visualising the residual dependency structure in distributed representations such as those produced by independent component analysis (ICA). This process involves estimating the mutual information between many pairs of components, for which use a method based on nonlinear correlations. The pairwise dependencies are then represented geometrically using multidimensional scaling (MDS) in such a way that strongly dependent components are brought close together. The method is applied to ICA representations of speech and music audio signals. The resulting geometric structures reflect the time-frequency structure of the speech-derived ICA representation and a more complex relationship, related to the harmonic structure of Western musical scales, between frequencies in the music-derived representation.
Summarization: Constructing an Ideal Summary and Evaluating a Student's Summary Using LSA

Summarization means getting the essence of the original document. The summary should be shorter than the original with all minor facts left out and only the main ideas extracted and paraphrased with new words. This work aims to construct an ideal summary from sentences chosen as targets for self-explanations in prior experiments and to use this summary to assess the quality of students' summaries of the same text. This paper briefly describes (1) how ideal summary is systematically constructed based on the target sentences and (2) how LSA is used to measure the similarity between student's summary and ideal summary. Results indicate that target sentences are good indicators for an ideal summary. Comparison against human expert, the initial data shows that the system able to obtain 70-75% agreement in evaluating completeness of student summary and 0.65-0.74 correlation in evaluating quality of student summary.
Selectivity in the Use of Gi/o Proteins Is Determined by the DRF Motif in CXCR6 and Is Cell-Type Specific

CXCR6, the receptor for CXCL16, is expressed on multiple cell types and can be a coreceptor for human immunodeficiency virus 1. Except for CXCR6, all human chemokine receptors contain the D3.49R3. 50Y3.51 sequence, and all but two contain A3.53 at the cytoplasmic terminus of the third transmembrane helix (H3C), a region within class A G protein–coupled receptors that contacts G proteins. In CXCR6, H3C contains D3.49R3. 50F3.51I3. 52V3.53 at positions 126–130. We investigated the importance and interdependence of the canonical D126 and the noncanonical F128 and V130 in CXCR6 by mutating D126 to Y, F128 to Y, and V130 to A singly and in combination. For comparison, we mutated the analogous positions D142, Y144, and A146 to Y, F, and V, respectively, in CCR6, a related receptor containing the canonical sequences. Mutants were analyzed in both human embryonic kidney 293T and Jurkat E6-1 cells. Our data show that for CXCR6 and/or CCR6, mutations in H3C can affect both receptor signaling and chemokine binding; noncanonical H3C sequences are functionally linked, with dual changes mitigating the effects of single mutations; mutations in H3C that compromise receptor activity show selective defects in the use of individual Gi/o proteins; and the effects of mutations in H3C on receptor function and selectivity in Gi/o protein use can be cell-type specific. Our findings indicate that the ability of CXCR6 to make promiscuous use of the available Gi/o proteins is exquisitely dependent on sequences within the H3C and suggest that the native sequence allows for preservation of this function across different cellular environments.
Geometry Influence on GDOP in TOA and AOA Positioning Systems

Geometric dilution of precision (GDOP) is defined as the ratio of the root-mean-square position determination error to the root-mean-square measurement error. Based on the Cramer-Rao lower bound (CRLB), new mathematical expressions of GDOP are presented in Time-of-Arrival (TOA) and Angle-of-Arrival (AOA) positioning systems in this paper. The expressions obviously reveal that the geometrical shape of the anchor nodes make a significant influence on GDOP. Then the influence of adding a new anchor node at different locations is analyzed. Simulations show that in both positioning systems, two optimal placement angles exist to make the GDOP smallest, when the original anchor nodes are no uniformly scattered. However, when uniformly scattered, the GDOP keeps constant no matter what angle the new anchor node is placed at. In AOA positioning systems, the GDOP is also affected by the distance between the newly added anchor node and the target, and increases when the distance increases. Meanwhile, the GDOP is always reduced when more anchor nodes are used.
Reduced eosinophil apoptosis in induced sputum correlates with asthma severity

This study was carried out to investigate the relationship between induced sputum eosinophil apoptosis and clinical severity score, airway obstruction and symptom scores in patients with chronic stable asthma. Altogether, 41 chronic stable asthmatic subjects of varying severity defined by Aas score and 17 control subjects underwent spirometry, symptom questionnaire and successful sputum induction. Sputum was processed and cytospins prepared for light microscopy to determine normal and apoptotic eosinophils. Mild asthmatic subjects had a significantly lower percentage sputum eosinophils and a significantly higher eosinophil apoptotic ratio (AR) than moderate or chronic severe asthmatics. Severe asthmatic subjects had a significantly greater age, duration of asthma and sputum eosinophil count·mL−1 than mild asthmatic subjects. Asthmatic subjects' symptom scores, severity scores and age inversely correlated with AR and the percentage of sputum eosinophils. Baseline forced expiratory volume in one second inversely correlated with percentage sputum eosinophils and positively correlated with AR. The study demonstrates a relationship between reduced sputum eosinophil apoptosis and increased clinical severity of chronic stable asthma, providing additional evidence that eosinophil apoptosis may be important in the resolution of eosinophilic airway inflammation in asthma.
Posttranscriptional repression of the cel gene of the ColE7 operon by the RNA-binding protein CsrA of Escherichia coli

Carbon storage regulator (CsrA) is a eubacterial RNA-binding protein that acts as a global regulator of many functionally diverse chromosomal genes. Here, we reveal that CsrA represses expression from an extrachromosomal element of Escherichia coli, the lysis gene (cel) of the ColE7 operon (cea-cei-cel). This operon and colicin expression are activated upon SOS response. Disruption of csrA caused ∼5-fold increase of the lysis protein. Gel mobility shift assays established that both the single-stranded loop of the T1 stem–loop distal to cei, and the putative CsrA binding site overlapping the Shine–Dalgarno sequence (SD) of the cel gene are important for CsrA binding. Substitution mutations at SD relieved CsrA-dependent repression of the cel gene in vivo. Steady-state levels and half-life of the cel mRNA were not affected by CsrA, implying that regulation is mediated at the translational level. Levels of CsrB and CsrC sRNAs, which bind to and antagonize CsrA, were drastically reduced upon induction of the SOS response, while the CsrA protein itself remained unaffected. Thus, CsrA is a trans-acting modulator that downregulates the expression of lysis protein, which may confer a survival advantage on colicinogenic E. coli under environment stress conditions.
Iris Recognition Using Fuzzy Min-Max Neural Network

Iris is one of the best biometric features for security applications. This paper focuses on the iris recognition and classification system and its performance in biometric identification system. The steps of iris recognition include image normalization, feature extraction and classifier. This work is an application of Patrick Simpson’s fuzzy min-max neural network (FMN) Classification. Fuzzy min-max classification neural networks are built using hyperbox fuzzy sets. We performed comparative studies of different similarity measures applied to various classifiers. The feasibility of the FMN Classification Algorithm has been successfully evaluated on CASIA database with 756 images and found superior in terms of generalization and training time with equivalent testing time.
Using Traffic Analysis to Identify the Second Generation Onion Router

Anonymous networks provide security for users by obfuscating messages with encryption and hiding communications amongst cover traffic provided by other network participants. The traditional goal of academic research into these networks has been attacks that aim to uncover the identity of network users. But the success of an anonymous network relies not only on it's technical capabilities, but on adoption by a large enough user base to provide adequate cover traffic. If anonymous network nodes can be identified, the users can be harassed, discouraging participation. Tor is an example of widely used anonymous network which uses a form of Onion Routing to provide low latency anonymous communications. This paper demonstrates that traffic from a simulated Tor network can be distinguished from regular encrypted traffic, suggesting that real world Tor users may be vulnerable to the same analysis.

Tarsos: a platform to explore pitch scales in non-western and western music

This paper presents Tarsos 1 , a modular software platform to extract and analyze pitch and scale organization in music, especially geared towards the analysis of non-Western music. Tarsos aims to be a user-friendly, graphical tool to explore tone scales and pitch organization in music of the world. With Tarsos pitch annotations are extracted from an audio signal that are then processed to form musicologically meaningful representations. These representations cover more than the typical Western 12 pitch classes, since a fine-grained resolution of 1200 cents is used. Both scales with and without octave equivalence can be displayed graphically. The Tarsos API 2 creates opportunities to analyse large sets of ethnic - music automatically. The graphical user interface can be used for detailed, manually adjusted analysis of specific songs. Several output modalities make Tarsos an interesting tool for musicological analysis, educational purposes and even for artistic productions.
THE GAUSS-LUCAS THEOREM AND JENSEN POLYNOMIALS

A characterization is given of the sequences {"fyj^o vvith the property that, for any complex polynomial/(z) = 1akzk and convex region Kcontaining the origin and the zeros of/, the zeros of 2 y¡<akzk again lie in K. Many applications and related results are also given. This work leads to a study of the Taylor coefficients of entire functions of type I in the Laguerre-Pólya class. If the power series of such a function is given by 1 ykzk/k\ and the sequence {yk} is positive and increasing, then the sequence satisfies an infinite collection of strong conditions on the differences, namely A"yA > 0 for all n, k.
Using Videotape to Communicate with Parents of Students with Severe Disabilities

in their cost. and their appearance in numerous homes. video communication can be a practical means of communicating with parents. Videotape can provide parents with visual models of instruction, curriculum information. and evidence of their child's progress. As part of their needs assessment for training in Georgia. the State Comprehensive System of Personnel Delivery Committee surveyed parents to determine their preferred means of having educational experiences provided to them. Of the 1.047 parents responding, 48% indicated that they would prefer videotape. Parents indicated that it is much easier for them to take a tape home than to schedule meetings and arrange childcare. By having these tapes at home. parents are able to view them repeatedly for clarification. review of instructions, and additional information and to share information and procedures with other family members.
Adaptive defense measures against the security hazards induced by systems virtualisation

The explosive proliferation of systems virtualisation supports a more adaptive delivery of IT services. In the area of security management, however, virtualisation carries beneficial as well as detrimental implications. Fig. 1 shows the sources of requirements on security management: they originate either from technical sources, in a bottom-up view, or from high-level goals. As the business management is held liable for financial damage caused by IT security incidents, e. g. due to the BASEL II and SOX regulations [1,2,3], security measures are no longer a task which is exclusively handled by the IT staff. Governance, Risk, and Compliance (GRC) frameworks focus the support of these three business critical management areas on the strategic level.
Partitioning of a DRM receiver

In this article we present the results of partitioning the OFDM baseband processing of a DRM receiver into smaller independent processes. Furthermore, we give a short introduction into the relevant parts of the DRM standard. Based on the number of multiplications and additions we can map individual processes on a heterogeneous multi-tile architecture. This architecture can meet both the computational demands as well as the restricted energy budget.
Estimating Web Service interface complexity and quality through conventional object-oriented metrics

Historically, software engineers have conceived metric suites as valuable tools to estimate the quality of their software artifacts. Recently, a fresh computing paradigm called Service-Oriented Computing (SOC) has emerged at the crossing of massively distributed and heterogeneous software. This paper presents a statistical correlation analysis showing that classic software engineering metrics can be used to predict the complexity and quality of WSDL documents, the cornerstone software artifact when materializing this novel computing paradigm with Web-based technologies. For the experiments, 154 real world WSDL documents have been employed.
