Histogram comparison as a powerful tool for the search of new physics at LHC. Application to CMSSM

We propose a rigorous and effective way to compare experimental and theoretical histograms, incorporating the different sources of statistical and systematic uncertainties. This is a useful tool to extract as much information as possible from the comparison between experimental data with theoretical simulations, optimizing the chances of identifying New Physics at the LHC. We illustrate this by showing how a search in the CMSSM parameter space, using Bayesian techniques, can effectively find the correct values of the CMSSM parameters by comparing histograms of events with multijets + missing transverse momentum displayed in the effective-mass variable. The procedure is in fact very efficient to identify the true supersymmetric model, in the case supersymmetry is really there and accessible to the LHC

Revisión de la técnica "el juego del buen comportamiento"

El Juego del Buen Comportamiento, JBC (Good behavior Game, GBG), tiene como objetivo fundamental reducir la frecuencia de determinados comportamientos disruptivos en el aula como gritar, pelearse, interrumpir, etc. Dichos comportamientos se caracterizan por ser funcionales en ciertos contextos como el recreo o el juego libre entre compañeros, y disfuncionales en situaciones educativas. El objetivo de este artículo es presentar una revisión sobre todos los trabajos que han contribuido a mejorar la eficacia de este procedimiento, con la intención de darlo a conocer y promover estudios que indaguen en sus limitaciones (generalización y mantenimiento). Para ello, se presentan los aspectos generales del juego: organización de la clase, criterios para el refuerzo, dónde y cuánto tiempo dura el juego, tipo de refuerzos recibidos, comportamientos disruptivos a tratar; y las diferentes aplicaciones que se han realizado del mismo. A modo de conclusión, parece que este procedimiento se presenta muy eficaz para reducir la frecuencia de comportamientos disruptivos en contextos educativosThe Good Behavior Game (GBG), has as main objective to reduce the frequency of disruptive behavior in the class like: shauting, fighting, in terrupting, etc. These behaviors are characterized by being functional in certain contexts Iike the playground or the free-game among partners and disfunctional in instructiona/-academic settings. The main aim of this article is to make a review about the published works that have contributed to implement its efficacy, and to promote some pieces of work that deals with their limits (generalization and management). The general aspects of the game are presented, class organization, support criteria where and how long the game willlast, kind of support or reinforcements received, behavio'ur disruptive to deal with and the different applications that the Good Behavior Game. To conclude, it seems that this procedure is presented very efficiently in order to reduce the frequency of disruptive behaviour in educational context

p-Summing Bloch mappings on the complex unit disc

The notion of $p$-summing Bloch mapping from the complex unit open disc $\mathbb{D}$ into a complex Banach space $X$ is introduced for any $1\leq p\leq\infty$. It is shown that the linear space of such mappings, equipped with a natural seminorm $\pi^{\mathbb{B}}_p$, is M\"obius-invariant. Moreover, its subspace consisting of all those mappings which preserve the zero is an injective Banach ideal of normalized Bloch mappings. Bloch versions of the Pietsch's domination/factorization Theorem and the Maurey's extrapolation Theorem are presented. We also introduce the spaces of $X$-valued Bloch molecules on $\mathbb{D}$ and identify the spaces of normalized $p$-summing Bloch mappings from $\mathbb{D}$ into $X^*$ under the norm $\pi^{\mathbb{B}}_p$ with the duals of such spaces of molecules under the Bloch version of the $p$-Chevet--Saphar tensor norms $d_p$.Comment: 23 pages. Introduced some corrections on the first version. Accepted for publication in Banach Journal of Mathematical Analysi

Analysis of behavior related to use of the Internet, mobile telephones, compulsive shopping and gambling among university students

El objetivo de este trabajo de investigación es conocer los hábitos relacionados con posibles conductas adictivas (juego patológico, Internet, compras, uso del teléfono móvil, etc.) que pueden presentar los jóvenes estudiantes de la Universidad de Córdoba (España), y relacionar dichos comportamientos con variables como la edad, el sexo, el curso y las macroáreas de conocimiento (letras y ciencias). Con un diseño expostfacto de grupo único (Montero y León, 2007), se elaboró un cuestionario de datos sociodemográficos en el que se incluía el Test de adicción a las compras, el Test de adicción a Internet de Echeburúa (2003), el Cuestionario Breve de Juego Patológico de Fernández-Montalvo y Echeburúa (1997) y algunos ítems sobre el uso del teléfono móvil. Participaron 1011 estudiantes, 42,7% hombres y 57,3% mujeres, con un rango de edad entre los 18 y 29 años. Se dan diferencias estadísticamente significativas entre la puntuación media obtenida en los cuestionarios y variables como la edad, el sexo, el curso o la macroárea de conocimiento. Parece que ser mujer es un factor protector para la adicción a Internet y al Juego, ser de ciencias es un factor de riesgo para una posible adicción al Juego, ser de letras y tener más edad son factores de riesgo ante una posible adicción a las Compras. En conclusión, los estudiantes encuestados realizan un uso moderado de conductas como navegar por Internet, el juego, las compras y el teléfono móvil, siendo un grupo muy reducido de jóvenes los que sí se encuentran cercanos a tener un problema de adicción con este tipo de comportamientos.The aim of this study is to obtain knowledge about habits related to addictive behaviour (pathological gambling, Internet, compulsive shopping, use of mobile telephones, etc.) that may be displayed by young students at the University of Cordoba (Spain), and to relate this behaviour with variables such as age, sex, course year, macro-field of study (arts/sciences) and the consumption of substances such as alcohol, tobacco, cannabis and cocaine. Using an ex-post facto single-group design (Montero & León, 2007), we applied a questionnaire especially designed to gather socio-demographic information on substance use and behavioural patterns related to “non-substance” addictions, which included the Shopping Addiction Test, Echeburúa’s Internet Addiction Test (2003) and Fernández-Montalvo and Echeburúa’s Short Pathological Gambling Questionnaire (1997). A total of 1,011 students participated in the study (42.7% males and 57.3% females), with an age range of 18 to 29. Significant differences were found between mean score on the questionnaires and variables such as age, sex, field of studies and course year. It would seem that being female is a protective factor for Internet and gambling addiction, being a sciences student is a risk factor for gambling addiction, and being older and being an arts student are risk factors for shopping addiction. In conclusion, it can be stated that the students surveyed showed moderate incidence of behaviours such as Internet browsing, gambling, shopping and mobile phone use, whilst a very small group are close to having an addiction problem with such behaviour

A Review about Parenting Style and Parenting Practices and Their Consequences in Disabled and Non Disabled Children

In order to explain the worst levels of adaptation showed by children with disabilities in relation to non disabled children, this paper aims to carry out a review of the most important advances achieved in recent decades in the study of parenting styles and parenting practices in relation to academic competence and behavior problems of children with and without disabilities. For this, we have carried out an analysis of the main works that show this relationship in the population, and then, we did the same including disability as a differentiating factor. In this sense, the authoritative style and specific parenting practices such as setting limits, communication, autonomy or monitoring are described as good predictors of adaptive behavior in children. However, we miss studies to confirm this relationship in children with disabilities. In this population, most of the papers refer, on the one hand, to expectations and, on the other hand, the stress in parenting and its effect on the parents’ mental health. In conclusion, the need to provide additional information about family relationships and disability is discusse

Relationship Between Parenting Style and Aggression in a Spanish Children Sample

The aim of this study is to ascertain whether there are any differences in the parenting style received by two groups of children who obtain low-risk and high-risk scores, respectively, in relation to aggressive behaviour and determine which parenting variables are linked with the presence or absence of this kind of problematic behaviour. We selected a sample of 33 children between 3 and 14 years old (21 male and 12 female) with risk scores in aggressive behaviour and another similar group with low scores in this variable. After administering both instruments to the parents, we carried out a binomial logistic regression analysis which resulted in a prediction model for the 87.9% of the sample, made up of the parenting variables: father‟s satisfaction with parenting and role orientation, and mother‟s autonomy and limit setting. Moreover, our analysis of the variance revealed significant differences in the support and communication perceived by the fathers and mothers of both groups. Lastly, the utility of results to propose intervention strategies within the family based on fathers involvement and an authoritative style is discussed

Quimioesterilización de Anastrepha fraterculus (Diptera: Tephritidae) con un regulador del crecimiento de insectos

Anastrepha fraterculus is a fruit pest of economic importance in South America and northwestern Argentina. Currently, it is controlled with toxic baits but there is a demand for environmentally acceptable methodologies. The use of inhibitors of the chitin synthesis is proposed as a tool to sterilize adults in the field. The aim of this study was to evaluate the efficacy of different doses of lufenuron to generate chemosterilization in A. fraterculus. Three experiments were performed. In the first two, the product was incorporated into the diet of the adults from emergence to sexual maturity. Treated individuals from one sex were crossed with untreated individuals from the other sex. Eggs were collected and allowed embryonic development. In the third trial, untreated males and females were crossed and allowed to copulate. Subsequently, females were exposed to the product and the eggs were collected. Egg hatch was affected in the three experiments in a dose dependent way. In Experiment 3, the effect of the product was evidenced 48 hours after exposure. Fecundity was also affected when the females were the treated sex. The results show that exposure of adults to lufenuron reduces egg hatch in A. fraterculus encouraging further investigations to adapt this methodology for this species.Fil: Ruiz, J. E..

His-Bundle Pacing in a Patient With Tricuspid and Mitral Prosthetic Valves Without Suitable Coronary Veins for Lead Placement

Atrioventricular block in patients with a prosthetic tricuspid valve and a pacemaker with a dysfunctional epicardial lead is not uncommon. In such instances, coronary sinus lead placement is the preferred option, but it has a failure rate of 10%-15%. An atrial transseptal left ventricular lead placement has been proposed as an alternative, but this approach is not feasible in patients with a prosthetic mitral valve. This analysis represents the first reported case of His-bundle pacing from the atria in a patient with prosthetic tricuspid and mitral valves, with no suitable coronary veins for lead placement. © 2021 The Author

The de novo production of halogenated hydroquinone metabolites by the Andean-Patagonian white-rot fungus Phylloporia boldo

The production of halogenated hydroquinone metabolites such as drosophilin A, drosophilin A methyl ether and chloroneb was investigated in the Andean-Patagonian fungus Phylloporia boldo. These chlorinated compounds were detected in both fruiting bodies and living cultures. Gas chromatography-mass spectrometry (GC-MS) quantification of these molecules was performed in liquid media giving similar values in comparison to previous reports. We observed the concentration of drosophilin A, drosophilin A methyl ether and chloroneb increased in liquid culture supplemented with KCl. Furthermore, chlorinated hydroquinone compounds were not detected using liquid media supplemented with KBr. Instead, brominated aromatic molecules were observed and quantified by gas chromatography-mass spectrometry. We consider these results are relevant for the use of these halogenating microorganisms in biotransformation processes.Fil: Riquelme, C.. Universidad de Concepción; ChileFil: Candia, B..

Deformation heterogeneity study of a 6061-T6 aluminum alloy processed by equal channel angular pressing

Among the severe plastic deformation techniques, the equal channel angular pressing (ECAP) has drastically improved the mechanical properties of the processed alloys. However, information regarding friction phenomenon, which modifies the deformation at the surface and the heterogeneity microstrain state produced by the process itself, is still scarce. In the present work, the deformation heterogeneity and the friction effect, at the surface in the bulk material of the 6061-T6 aluminum alloy processed by ECAP, is presented and discussed. The residual stress (RS) measurements were performed by means of X-Ray diffraction. By means of synchrotron diffraction, volumetric sections of the ECAPed samples were characterized. Finite element analysis showed a good agreement with the experimentally obtained residual stress and microhardness mapping results. The study also showed that the highest deformation zones were located at the outer parts of the deformed samples (top and bottom), while the inner zone showed strain oscillations of up to 49±2 MPa.Peer ReviewedPostprint (author's final draft
