We study the LHC phenomenology of flavor changing Yukawa couplings between the top quark, the Higgs boson, and either an up or charm quark. Such tuh or tch couplings arise for instance in models in which the Higgs sector is extended by the existence of additional Higgs bosons or by higher dimensional operators. We emphasize the importance of anomalous single top plus Higgs production in these scenarios, in addition to the more widely studied t → hj decays. By recasting existing CMS searches in multilepton and diphoton plus lepton final states, we show that bounds on ℬ\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ \mathrm{\mathcal{B}} $$\end{document}(t → hu) are improved by a factor of 1.5 when single top plus Higgs production is accounted for.

We then investigate the sensitivity of future searches in the multilepton channel and in the fully hadronic channel. In multilepton searches, studying the lepton rapidity distributions and charge assignments can be used to discriminate between tuh couplings, for which anomalous single top production is relevant, and tch couplings, for which it is suppressed by the parton distribution function of the charm quark. An analysis of fully hadronic t + h production and t → hj decay can be competitive with the multilepton search at 100 fb−1 of 13 TeV data if jet substructure techniques are employed to reconstruct boosted top quarks and Higgs bosons. To show this we develop a modified version of the HEPTopTagger algorithm, optimized for tagging t → hj decays.

BACKGROUND/AIM Acne is well recognized condition that adversely affects quality of life (QoL) of the patients. The aim of this study was to determine the self-reported prevalence of acne and its main characteristics in high school pupils, and to assess their QoL. METHODS The cross-sectional study conducted in May 2011 comprised 440 pupils from Serbia (281 from Belgrade and 159 from Uzice). Participation in the study was voluntary and anonymous. Two questionnaires were administered: a short demographic questionnaire, and Children's Dermatology Life Quality Index (CDLQI). Internal consistency was assessed using the Cronbach's alpha while item-total score correlations were assessed using Spearman's correlation analysis. RESULTS The majority of the study population (84.3%) were girls, and 15.7% were boys. The total mean age of the pupils was 16.48 +/- 0.55 years. A total of 228 (51.8%) pupils self-reported their acne with significantly higher prevalence in Uzice (73.6%) than in Belgrade (39.5%). The mean CDLQI score was 3.55 with the similar quality of life impairment in adolescents from the two cities. The mean Cronbach's alpha was 0.83. There was a statistically significant positive correlation between the mean overall CDLQI score and CDLQI subscale scores that ranged from 0.401 to 0.841. CONCLUSION Our study confirmed that acne is associated with impairment in QoL that is in accordance with previous studies performed on teenagers. The CDLQI is a reliable and valid measure, and can be used as a practical tool for measuring the impact of acne on patients' QoL.

In recent years a growing number of companies modified their innovation process. Especially after the recent financial downturn, companies are looking for much more efficient and creative business processes. The aim of the presented paper is to present a decision support tool or in other words a software system for the application of the AHP method to support innovative and strategic process. Few studies propose analytic quantitative methods to elicit user/stakeholders needs, and among those a method that seems to be particularly effective to elicit user need was the Analytic Hierarchy Process (AHP).

No presente trabalho avaliou-se o emprego do processo de osmose inversa na remocao de ions Ni 2+ e Cu 2+ de efluentes sinteticos que consistiram de solucoes aquosas de sais destes ions. Diante da capacidade desses ions formarem complexos com EDTA, avaliou-se a eficiencia de uma etapa previa de complexacao do ion metalico. O sistema experimental consistiu de um reator com membrana plana comercial de poliamida e fluxo transversal. Estudos empregando solucoes com apenas um dos ions e tambem com mistura desses, em diferentes faixas de concentracao, indicaram rejeicoes em torno de 99%. O emprego do agente complexante nao afetou de forma significativa a remocao do ion metalico, mas contribuiu para a manutencao do fluxo permeado mediante a reducao da formacao de incrustacoes ao longo do tempo de operacao. Estudos realizados sob diferentes pressoes demonstraram que a elevacao desta esta variavel exerce um efeito sobre o aumento da rejeicao e do fluxo permeado.

Sažetak: U sprinterskim disciplinama vrlo važno mjesto zauzimaju start i startno ubrzanje koje u velikoj mjeri generise konacni rezultat. U zavisnosti od odgovarajucih individualnih morfoloskih dimenzija, a narocito motorickih i funkcionalnih sposobnosti takmicara mogucnost dobre realizacije ovih parametara je izvjesnija. Međutim, i pored vrhunskih rezultata koje ostvaruju, razlike u ova dva parametra su evidentne, sto u pogledu na konacni rezultat ima određenog efekta. Cilj ovog istraživanja je bio da se utvrde razlike u vremenu startne reakcije i rezultata u sprinterskim disciplinama finalista Olimpijskih igara u Londonu 2012. godine. Analizirani su rezultati finalista (24 muska) i 24 (ženska) takmicara koji su nastupili u finalnim trkama na 100m, 200m i 400m. Evaluacija vremena startne reakcije (ms) i rezultata u sprintu (s) bazirala se na izvjestajima koje je službeno objavila Međunarodna atletska federacija (IAAF). Rezultati analize T-testa su pokazali statisticki znacajne razlike u vremenu reakcije kod ženskih takmicara u disciplinama trcanja 100m i 400m (t= -3,220; p<0,01) kao i za discipline 200m i 400m (t=-2,550; p<0,01), za razliku od muskih finalista gdje nisu zabilježene statisticki znacajne razlike. Takođe, u istim disciplinama između polova nisu zabilježene statisticki znacajne razlike, dok su evidentne u postignutim rezultatima u disciplinama 100m (t=-2,842; p<0,05), 200m (t=-11,526; p<0,01) i 400m (t=-27,019; p<0,01).

Abstract: The measuring of implemented ERP system’s efficiency is in any case multidimensional. Various researchers dedicated a lot of attention trying to find the best way to measure the success or the effectiveness of ERP solution. „Customer satisfaction“ as a measure represents the crucial point in creating the model for Measuring the success of implemented ERP systems and therefore it is the subject of this work. In this work we shall see what effect the other measurements will have on the „customer satisfaction“, respecting the correlation between particular crucial categories in creating the model of implemented ERP system’s success.

Este trabalho tem por objetivo investigar como a producao oral e abordada num livro didatico, aprovado pelo PNLD (Programa Nacional do Livro Didatico – 2011: Lingua Estrangeira Moderna), em comparacao com os parâmetros estabelecidos pelo proprio Programa. Dentre os dados coletados, o presente estudo focaliza a analise da secao que e especificamente voltada ao desenvolvimento das habilidades de producao oral. Com base na pesquisa documental e assumindo uma visao sociocultural de linguagem, discutimos em que medida as atividades apresentadas no livro didatico contribuem para a formacao de falantes de ingles, que sejam capazes de responder/reagir, adequadamente, aos varios generos orais que circulam em suas praticas sociais. Os resultados apontam que predominam, os textos criados, exclusivamente, para fins didaticos, e a abordagem do oral parece fundamentada em uma visao, ainda, tradicional de ensino de lingua.

In this paper we present some specific cases of the classic Nonlinear Lotka-Volterra (NLV) approach to modeling predator-prey dynamic systems [1,5], and propose to implement them using "mathematical" (Matlab) approach as well as "ad-hoc" approach using Agent Based Modeling (implemented using NetLogo modeling environment), [6].   Examples of various scenarios are introduced in a gradual way, from simpler to more complex ones. The emphasis is given to gaining insight into predator-prey relationship, as well as some structural results [2,3] as applied to classic complex systems modeling and control, as well as understanding stability in multispecies communities. The paper sets the scene for further research using NLV (mathematical) and ABM (ad-hoc) models. With this "parallel" approach we hope to address some classic problems such as Gause's Law and Paradox of the Plankton,  Paradox of Enrichment (system level instability), Oksanen's description and trophic level numbers,  and other current Complex Systems paradigms such as adaptivity, emergence, etc..

This paper tries to explore issues in terms of business ethics and CSR in Bosnia and Herzegovina. We examined 54 companies by using convenience sampling method. We explored descriptive statistics and non probability data analysis. With Spearman’s correlation test we found possible relationships within some issues within the survey parameters that we examined. Conclusions have been derived from this study. For analysis we used a software for social sciences namely SPSS, version 21.

Microstrip antennas synthesis is a demanding task; many of the equations involved in the process use various approximations due to the nonlinear properties and relations that govern the antenna synthesis. In This paper we tried to use genetic algorithm to design a circular microstrip ring that operates in a predefined frequency band (402 – 405 MHz) Medical Implant Communication Service Frequency Band. The methodology and procedures are presented, a presentation of the method is provided and an HFSS simulation of the antenna is made. Results are presented with guidelines for further future work
