1 p, 710.4 KB Correction : Analysis of zero inflated dichotomous variables from a Bayesian perspective: application to occupational health / Moriña, David (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Puig, Pedro (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Navarro Giné, Albert (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
Zero-inflated models are generally aimed to addressing the problem that arises from having two different sources that generate the zero values observed in a distribution. In practice, this is due to the fact that the population studied actually consists of two subpopulations: one in which the value zero is by default (structural zero) and the other is circumstantial (sample zero). [...]

We report quantum mechanical/molecular mechanical non-adiabatic molecular dynamics simulations on the electronically excited state of green fluorescent protein mutant S65T/H148D. We examine the driving force of the ultrafast (τ < 50 fs) excited-state proton transfer unleashed by absorption in the A band at 415 nm and propose an atomistic description of the two dynamical regimes experimentally observed [Stoner Ma et al.

Departament d'Estadística i Investigació Operativa) ; Carrasco, Josep Lluís (Universitat de Barcelona) ; Rönnegård, Lars (Dalarna University (Falun, Suècia). Statistics Unit)
Generalized linear mixed models are flexible tools for modeling non-normal data and are usefulfor accommodating overdispersion in Poisson regression models with random effects. Theirmain difficulty resides in the parameter estimation because there is no analytic solution for themaximization of the marginal likelihood. [...]

Methodologies for sensitivity analysis are considered to be of great importance for analyzing agent-based models (ABMs), even more because calibration and validation of ABMs often prove problematic. Different methodologies for sensitivity analysis may help to understand ABM dynamics and (thus) aid in the calibration and validation of ABMs. [...]

Europe suffers approximately 65,000 fires every year, which burn, on average, half a million hectares of forest areas [1]. The main direct effect of forest fires is the destruction of the natural landscape and the consequent loss of ecosystem service that have drastic economic impact, but mainly and much more important, fires also result in the loss of human lives every year.
