Is \lq\lq Heavy Quark Damping Rate Puzzle'' in Hot QCD Really the Puzzle?

Within the framework of perturbative resummation scheme of Pisarski and Braaten, the decay- or damping-rate of a moving heavy quark (muon) to leading order in weak coupling in hot QCD (QED) is examined. Although, as is well known, the conventionally-defined damping rate diverges logarithmically at the infrared limit, shown is that no such divergence appears in the physically measurable decay rate. The cancellation occurs between the contribution from the \lq\lq real'' decay diagram and the contribution from the diagrams with \lq\lq thermal radiative correction''.Comment: 13pages, OCU-PHYS-15

Finite-temperature reaction-rate formula: Finite volume system, detailed balance, T→0T \to 0 limit, and cutting rules

A complete derivation, from first principles, of the reaction-rate formula for a generic process taking place in a heat bath of finite volume is given. It is shown that the formula involves no finite-volume correction. Through perturbative diagrammatic analysis of the resultant formula, the detailed-balance formula is derived. The zero-temperature limit of the formula is discussed. Thermal cutting rules, which are introduced in previous work, are compared with those introduced by other authors.Comment: 35pages (text) plus 4pages (figures

Dimensionality dependence of optical nonlinearity and relaxation dynamics in cuprates

Femtosecond pump-probe measurements find pronounced dimensionality dependence of the optical nonlinearity in cuprates. Although the coherent two-photon absorption (TPA) and linear absorption bands nearly overlap in both quasi-one and two-dimensional (1D and 2D) cuprates, the TPA coefficient is one order of magnitude smaller in 2D than in 1D. Furthermore, picosecond recovery of optical transparency is observed in 1D cuprates, while the recovery in 2D involves relaxation channels with a time scales of tens of picoseconds. The experimental results are interpreted within the two-band extended Hubbard model.Comment: 10 pages, 4 figure

El valle en el cuenco. Cerámica desde el territorio. Distribución alternativa

El valle en el cuenco es un proyecto de investigación que estudia al Valle de Atemajac, sitio donde reside la actual Guadalajara y propone una práctica cerámica artesanal responsable que consiste en crear desde el entorno natural nativo. El proyecto surge del nombre del PAP, “Mirar la ciudad con otros ojos. Memorias e identidades”; en este caso, la ciudad de Guadalajara y el territorio del Valle de Atemajac se miran desde los ojos del ceramista. El corazón del proyecto reside en la búsqueda de resignificar y volver a dar valor al entorno y a los recursos naturales y al mismo tiempo, al oficio y a los procesos cerámicos. La metodología de desarrollo de proyecto consta de una investigación teórica y práctica que se va desenvolviendo en dos etapas. La primera etapa, que se lleva a cabo en el semestre actual, consiste en conocer el territorio y el quehacer cerámico que se desenvuelve en él, para posteriormente desarrollar un método artesanal cerámico que se basa en crear responsablemente desde los recursos naturales nativos del territorio, ahondando en los componentes del cuerpo y la superficie cerámica, en las características de los materiales naturales aplicables al quehacer cerámico, en la identificación, propiedades y procesamiento de los recursos naturales nativos para posteriormente, elaborar pastas, engobes, pátinas y esmaltes. La segunda etapa, que se desarrollará el siguiente semestre, radica en una investigación cerámica de carácter práctico que se enfoca en profundizar en los procesos y bondades que conlleva crear desde el entorno. En descubrir las posibilidades que ofrecen los recursos naturales nativos en el quehacer del ceramista. El desarrollo consiste en identificar y estudiar los recursos nativos del territorio que tienen una aplicación directa en el oficio del ceramista, en recolectar y procesar artesanalmente los materiales naturales nativos y, por último, realizar pruebas de pastas, esmaltes, engobes y pátinas en el taller, registrando y documentando los procesos y resultados. El proyecto busca concluir la investigación plasmando el paisaje del Valle de Atemajac en una serie de cuencos cerámicos con el sustento teórico y práctico del estudio del territorio y las pruebas cerámicas realizadas con la intención de crear un patrimonio artístico–natural–cultural que difunda la importancia de honrar la Tierra y los procesos humanos que provienen de ella.ITESO, A.C

Ventricular Tachycardia in Repaired Double Chambered Right Ventricle - Identification of the Substrate and Successful Ablation

A 35 year old female presented with recurrent ventricular tachycardia 5 years after she had undergone surgical repair of double chambered right ventricle. Electroanatomical mapping showed a localised scar in the apex with double potentials and good pace map. Ablation here resulted in non-inducibility of ventricular tachycardia. We hypothesise that the scarring in the apex is the result of sustained pressure overload and becomes arrhythmogenic similar to the apical scar in patients with mid-ventricular hypertrophic cardiomyopathy

Dissertação de mestrado em Psicologia Clínica e Saúde (Psicopatologia e Psicoterapia Dinâmica), apresentada à Faculdade de Psicologia e Ciências da Educação da Universidade de CoimbraOs pacientes infetados pelo VIH têm sido objeto de interesse por parte dos profissionais de saúde mental pela dimensão do impacto psicológico do diagnóstico, evolução da infeção e a vulnerabilidade destes sujeitos. Seja como for, em traço de evolução da terapêutica, a infeção pelo vírus da imunodeficiência humana (VIH) é, atualmente, uma doença tendencialmente crónica. Entre as perturbações mentais, a depressão é descrita como uma das comorbidades mais frequentes nos indivíduos com VIH e que muitas vezes passa despercebida. Acompanha-se de elevada morbilidade e apresenta um impacto sócio-económico, sendo uma das causas mais frequentes de suicídio. Para além da incapacidade que se vai instalando progressivamente, os indivíduos são confrontados com o estigma social, carência de apoio social e isolamento. Neste sentido, este estudo foi realizado com o intuito de chamar a atenção para a necessidade de intervenção psicoterapêutica com esta população, através da exploração dos sintomas psicopatológicos mais prevalentes (com especial destaque para a depressão e para a ideação suicida), tendo em consideração a progressão da doença e a as caraterísticas socio-demográficas.Patients infected with HIV have been the object of interest on the part of mental health professionals due to the dimension of the psychological impact of the diagnosis, the course of infection and the vulnerability of these subjects. Anyway, in trait evolution of therapy, infection by the human immunodeficiency virus (HIV) is currently a chronic disease. Among mental disorders, depression is described as one of the most frequent comorbidities in individuals infected with HIV and which often goes unnoticed. It is accompanied by high morbidity and presents a socialeconomic impact, being one of the most frequent causes of suicide. Beyond the progressively established disability, individuals face social stigma, lack of social support and isolation. Thus, this study was conducted in order to draw attention to the need for psychotherapeutic intervention among this population, through the exploitation of the most prevalent psychopathological symptoms (with special emphasis on depression and suicidal ideation), taking into account the progression of this disease and the social-demographic characteristics

Density of States and Energy Gap in Andreev Billiards

We present numerical results for the local density of states in semiclassical Andreev billiards. We show that the energy gap near the Fermi energy develops in a chaotic billiard. Using the same method no gap is found in similar square and circular billiards.Comment: 9 pages, 6 Postscript figure
