Final states with electrons, muons and hadronically decaying tau leptons are considered (eμ, eτ or μτ). No significant excess over the Standard Model predictions is observed. Upper limits on the production cross-section are set as a function of the mass of a Z′ boson, a supersymmetric τ-sneutrino, and a quantum black-hole. The observed 95% CL lower mass limits obtained on a typical benchmark model Z′ boson are 5.0 TeV (eμ), 4.0 TeV (eτ), and 3.9 TeV (μτ), respectively.

Work memory and inhibition in abused children
No full textIntroductionIt has been shown that children with a history of abuse tend to have a deficit in both their academic and cognitive abilities. Mesa-Gresa, P., & Moya-Albiol, L. (2011) [1]. This study aimed to identify the relationship between abuse (psychological, neglect, custody and abandonment) and the performance of executive functions of memory of verbal work and inhibition.MethodThe Executive Function battery (Gonzalez, M., & Ostrosky, F., 2012) [2] was applied to 38 preschoolers 4–5 year olds who have experience abuse and to 36 preschoolers who have not. Data was analysed using the test t for independent samples and the Chi-cuadrado from Pearson.ResultsInhibition was affected in children with psychological abuse and negligence. It means that children presented difficulty in controlling their behaviour. Children victim of abandonment showed lower performance of executive functions of memory of verbal work. Such function allows them to carry on daily activities efficiently. Conversely, children without previous history of abuse showed higher performance in both tests especially in inhibition.ConclusionFindings suggest that child abuse in preschoolers can influence the performance in their executive functions without difference in gender.Disclosure of interestThe author has not supplied his/her declaration of competing interest.</jats:sec
A portrait of the Spanish accounting community
No full textThis study presents a portrait of the Spanish academic accounting community in 1995, based upon a questionnaire circulated to Spanish accounting academics in 1995 and upon an analysis of authorship and citations in the main Spanish accounting journals. The approach to these analyses is grounded in similar studies which have been carried out in the United States, Spain and elsewhere. but the combination of techniques used in this study is particularly broad in range. The results of the study are used to describe a range of characteristics of Spanish accounting academics, for example, publications records and length of academic experience. The analysis of publications produces a ranking by institutional affiliation of the most significant contributors to current debates on accounting. Citation analysis is used to identify the range and extent of international influences upon the Spanish academic accounting community, and to provide an additional ranking by institutional affiliation of the most frequently cited sources A significant finding was that the nature and extent of international influence had changed very little over the ten year period since Spain entered the European Union and started to implement European Directives. Perceptions of journal quality were elicited by questionnaire. Forty five journals, Spanish and international are included in a list ranked for perceived importance as outlets for publication. and as sources of support for teaching and research. The results of this exercise show that Spanish journals were ranked low relative to journals published in the United Kingdom and United States. Finally the study examines the extent of purpose upon Spanish accounting academies to publish, by presenting results of a question about criteria for promotion, and also by examining and increasing tendency to publish co-authored work.Accounting, academic community

The analysed data collected with the ATLAS detector in proton-proton collisions at a centre-of-mass energy of 13 TeV at the Large Hadron Collider correspond to an integrated luminosity of 139 fb. Two invariant mass distributions are examined for a localised excess relative to the expected Standard Model background in six independent event categories (and their inclusive sum) to increase the sensitivity. No significant excess is observed. Exclusion limits at 95% confidence level are derived for two cases: a model-independent interpretation of Gaussian-shaped resonances with the mass width between 3% and 10% of the resonance mass, and a specific heavy vector triplet model with the decay mode W′ → ZW → ℓℓqq.

A data sample of proton–proton collisions at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider between 2015 and 2018 is used. The data correspond to a total integrated luminosity of 139 fb. The observed data are in agreement with Standard Model background expectations. The results are interpreted using higher-dimensional operators in an effective field theory. Upper limits on the production cross-section are calculated at 95% confidence level as a function of the heavy Higgs boson’s mass and coupling strengths to vector bosons. Limits are set in the Higgs boson mass range from 300 to 1500 GeV, and depend on the assumed couplings. The highest excluded mass for a heavy Higgs boson with the coupling combinations explored is 900 GeV. Limits on coupling strengths are also provided.

Improvements pertaining to the electroweak input scheme, parton-shower splitting kernels and scale-setting scheme are shown for multi-jet merged configurations accurate to next-to-leading order in the strong and electroweak couplings. The computational resources required for these set-ups are assessed, and approximations are introduced resulting in a factor three reduction of the per-event CPU time without affecting the physics modelling performance. Continuous statistical enhancement techniques are introduced by ATLAS in order to populate low cross-section regions of phase space and are shown to match or exceed the generated effective luminosity. This, together with the lower per-event CPU time, results in a 50% reduction in the required computing resources compared to a legacy set-up previously used by the ATLAS collaboration. The set-ups described in this paper will be used for future ATLAS analyses and lay the foundation for the next generation of Monte Carlo predictions for single vector-boson plus jets production.

On the stability of the PPH subdivision scheme on nonuniform grids
No full textOur purpose in this article is to prove the stability of the subdivision scheme associated with the PPH reconstruction on nonuniform grids. This subdivision scheme is convexity preserving and therefore quite interesting from the practical point of view. Therefore, it is also of utmost importance to count with a stability result ensuring its applicability in real cases. The theoretical stability has been proven for quasi-uniform grids with In the numerical experiments we analyze the sharpness of the given stability bound and of the restriction on the grids.The first author has been supported through CDTIM
