Kaluza-Klein Gluons as a Diagnostic of Warped Models

We study the properties of $g^{1}$, the first excited state of the gluon in representative variants of the Randall Sundrum model with the Standard Model fields in the bulk. We find that measurements of the coupling to light quarks (from the inclusive cross-section for $pp\to g^{1} \to t\bar t$), the coupling to bottom quarks (from the rate of $pp\to g^{1} b$), as well as the overall width, can provide powerful discriminants between the models. In models with large brane kinetic terms, the $g^1$ resonance can even potentially be discovered decaying into dijets against the large QCD background. We also derive bounds based on existing Tevatron searches for resonant $t \bar{t}$ production and find that they require $M_{g^{1}} \gtrsim 950$ GeV. In addition we explore the pattern of interference between the $g^1$ signal and the non-resonant SM background, defining an asymmetry parameter for the invariant mass distribution. The interference probes the relative signs of the couplings of the $g^{1}$ to light quark pairs and to $t\bar t$, and thus provides an indication that the top is localized on the other side of the extra dimension from the light quarks, as is typical in the RS framework.Comment: 25 pages, 10 figure

Revisiting the Un/Ethical: The Complex Ethics of Elite Studies Research

Current ethical codes inadequately speak to the complexities of researching elite groups. These groups contribute to broader inequalities and yet are protected from scrutiny by their own resources and, in the research context, ethical guidelines. For this reason, Gaztambide-Fernández (2015) called for those researching elite groups to adopt an ‘un/ethical’ position. This position circumvents conventional ethical codes to disrupt the power of research participants. In this paper, we put forward a considered assessment of this position. We reflect on and theorise our own experiences in the field from this ethical perspective, paying particular attention to our multifaceted insider/outsider statuses. We find that an un/ethical position offers short-term benefits but also does long-term damage to the elite studies scholar community. Thus, we counter-propose a way forward that dismantles power relations while avoiding the drawbacks of the un/ethical approach. Our proposal continues a necessary discussion around the ethics of elite studies research.Introduction Theorising research ethics Our experiences in the field In lieu of a conclusion: a way forward Notes Reference

MÉTODO DE EVALUCIÓN ESTRUCTURADA COMO HERRAMIENTA PARA EL CUIDADO FAMILIAR: EVALUACION DEL APGAR FAMILIAR

The importance of family assessment tools to the practicing family practice clinician cannot be stressed enough. Models are less practical than assessment tools and inventories in clinical practice. A structured method to evaluate assessment tools is presented. The Family APGAR is assessed using this method to demonstrate its usefulness to the family practice clinician. The intent of the structured method of evaluating each tool is to facilitate both the choice of a family assessment tool by the clinician and in the teaching of family assessment to those who use a family focus in their clinical care of patients.La importancia de tener instrumentos de evaluación para la practica clínica de la familia, no ha tenido el énfasis suficiente. Los Modelos son menos prácticos que sus instrumentos e inventarios en la práctica clínica un método estructurado para evaluar esos instrumentos. El APGAR Familiar es evaluado usando este método a fin de mostrar su utilidad al clínico de la práctica de familia. La intención del método estructurado de evaluar cada instrumento es facilitar la elección de un instrumento que empleado por el clinico sea aplicable a la familia y en el enseño de la evaluación de la familia la colocan como foco en el cuidado clínico de sus pacientes.A importância de instrumentos de avaliação para o praticante da prática clínica de família não tem tido a ênfase suficiente.

Charged Lepton Flavor Physics and Extra Dimensions

We estimate the charged lepton electric dipole moments and the branching ratios of radiative lepton flavor violating decays in the framework of the two Higgs doublet model with the inclusion two extra dimensions. Here, we consider that the new Higgs doublet is accessible to one of the extra dimensions with a Gaussian profile and the fermions are accessible to the other extra dimension with uniform zero mode profile. We observe that the numerical values of the physical quantities studied enhance with the additional effects due to the extra dimensions and they are sensitive to the new Higgs localization.Comment: 23 pages, 13 page

Profile of health-related quality of life outcomes after liver transplantation: univariate effects and multivariate models

AbstractAim. To test the effects of pre- and post-transplant clinical covariates on post-transplant health-related quality of life (HRQOL) score profiles in liver transplant recipients. Material and methods. HRQOL was measured before and after transplantation using the SF-36® Health Survey. Clinical data [diagnosis, model of end-stage liver disease (MELD) score, post-transplant rejection and infection episodes], pre-transplant functional performance (FP), and demographics were collected. Multivariate models for the eight SF-36 scales and two summary components were developed using multiple regression. Discriminant analysis was used to test whether the score profiles differentiated among recipients with and without hepatitis C virus (HCV) infection. Results. 104 adults reported pre- and post-transplant HRQOL. Time post-transplant averaged 9±8 months (range 1–39). Scores on all SF-36 measures improved from pre- to post-transplant (p<0.001), and 7 of 10 models were significant (p<0.05). After controlling for pre-transplant HRQOL and time post-transplant, HCV infection had a negative effect on the role physical, bodily pain, and role emotional scales. History of a rejection episode had a negative effect on the bodily pain and vitality scales. MELD scores ≥18 had a positive effect on the role physical scale. Pre-transplant FP and post-transplant infection episodes did not affect post-transplant HRQOL. HCV infection had a significant effect on the SF-36 score profile (canonical correlation=0.50; p<0.001). Conclusions. Pre-transplant HCV infection, MELD score, and post-transplant rejection episodes have significant independent effects on HRQOL after liver transplantation. Their specific effects vary among the individual SF-36 scales, and HRQOL score profiles differ among HCV+ and HCV– recipients

Observing Ultra High Energy Cosmic Particles from Space: SEUSO, the Super Extreme Universe Space Observatory Mission

The experimental search for ultra high energy cosmic messengers, from $E\sim 10^{19}$ eV to beyond $E\sim 10^{20}$ eV, at the very end of the known energy spectrum, constitutes an extraordinary opportunity to explore a largely unknown aspect of our universe. Key scientific goals are the identification of the sources of ultra high energy particles, the measurement of their spectra and the study of galactic and local intergalactic magnetic fields. Ultra high energy particles might, also, carry evidence of unknown physics or of exotic particles relics of the early universe. To meet this challenge a significant increase in the integrated exposure is required. This implies a new class of experiments with larger acceptances and good understanding of the systematic uncertainties. Space based observatories can reach the instantaneous aperture and the integrated exposure necessary to systematically explore the ultra high energy universe. In this paper, after briefly summarising the science case of the mission, we describe the scientific goals and requirements of the SEUSO concept. We then introduce the SEUSO observational approach and describe the main instrument and mission features. We conclude discussing the expected performance of the mission
