Mean first passage times of processes driven by white shot noise

The systems driven by white shot noise are analyzed based on mean first passage times. The shot noise has exponentially distributed jump heights. The the linkage between the results and the steady state probability density function of the process are presented

Evaluación frecuente, mentorías y rendimiento académico en el programa mentor de Aeronáuticos

El Programa Mentor de Aeronáuticos se inicia en 2004con una doble vertiente de actuación. Por un lado, Tutores y Mentores facilitan el proceso de integración de los Alumnos de Nuevo Ingreso en la vida universitaria; por otro, el estudio de las dificultades académicas de los Alumnos Tutelados conduce a Cambios Metodológicas en el Aula que ayudan a activar las relaciones profesor-alumno y a mejorar el rendimiento del esfuerzo de todos, profesores y alumnos. Se describen éstas experiencias, así como los resultados obtenidos en los últimos cuatro año

Occupational semicircular lipoatrophy associated with serum adipokine abnormalities

OBJECTIVES: The aim of this study was to examine the relationship between semicircular lipoatrophy (SL), inflammation marker (high sensibility C-reactive protein [hs-CRP]), adipokines (leptine, chemerine and vaspine) and autoimmune markers (rheumatoid factor [RF], C3 and C4 complement fractions, antinuclear antibodies [ANA], HLA DR3, and DR4). Chemerine is an adipokine, but also is an immunity marker. METHODS: A case-control study was performed in May 2013; 21 cases were included. The closest healthy coworker to each case was used as a control. We calculated Kruskal-Wallis nonparametric test. RESULTS: We found statistical significance (P<.05) between SL and raised hs-CRP, raised leptine and low chemerine. CONCLUSIONS: i) There seems to be an underlying inflammatory component (raised hs-CRP) in SL; ii) adipokine alteration (raised leptine and low chemerine) supports the idea that adipocytic differentiation is affected in SL, and iii) we have not found any immune marker associated with SL, except chemerine itself, which could explain a possible association between SL and immunity.1.267 JCR (2015) Q2, 74/151 Medicine, general & internalUE
