The Use of Rule-Based and QSPR Approaches in ADME Profiling: A Case Study on Caco-2 Permeability.
2013
During the early ADME profiling the development of simple, interpretable and reliable in silico tools is very important. In this study, rule-based and QSPR approaches were investigated using a large Caco-2 permeability database. Three permeability classes were determined: high (H), moderate (M) and low (L). The main physicochemical properties related with permeability were ranked as follows: Polar Surface Area (PSA)>Lipophilicity (logP/logD)>Molecular Weight (MW)>number of Hydrogen Bond donors and acceptors>Ionization State>number of Rotatable Bonds>number of Rings. The best rule, based on the combination of PSA-MW-logD (3PRule), was able to identify the H, M and L classes with accuracy of …

An adaptive approach to learning the preferences of users in a social network using weak estimators
2012
Published version of an article in the journal: Journal of Information Processing Systems. Also available from the publisher at: http://dx.doi.org/10.3745/JIPS.2012.8.2.191 - Open Access Since a social network by definition is so diverse, the problem of estimating the preferences of its users is becoming increasingly essential for personalized applications, which range from service recommender systems to the targeted advertising of services. However, unlike traditional estimation problems where the underlying target distribution is stationary; estimating a user's interests typically involves non-stationary distributions. The consequent time varying nature of the distribution to be tracked i…
La gestión de la programación teatral en España
2007
El sector de las artes escénicas ha destacado en los últimos años por un gran dinamismo y crecimiento. La mayor oferta y demanda de estas actividades culturales ha puesto de manifiesto la necesidad de gestionar el diseño de la programación desde una perspectiva más profesional, al tiempo que investigar esta materia. Sin embargo, son todavía escasos los estudios de naturaleza académica al respecto. En este sentido, los autores han desarrollado un estudio empírico centrado en responsables de programación de entidades escénicas españolas. Si bien el criterio de programación más valorado ha sido el perfil de la audiencia, ello no parece implicar una total aplicación de los principios y técnicas…
And Now for Something Completely Different: Running Lisp on GPUs
2018
The internal parallelism of compute resources increases permanently, and graphics processing units (GPUs) and other accelerators have been gaining importance in many domains. Researchers from life science, bioinformatics or artificial intelligence, for example, use GPUs to accelerate their computations. However, languages typically used in some of these disciplines often do not benefit from the technical developments because they cannot be executed natively on GPUs. Instead existing programs must be rewritten in other, less dynamic programming languages. On the other hand, the gap in programming features between accelerators and common CPUs shrinks permanently. Since accelerators are becomi…
Quantized Dissensus in switching networks with nodes death and duplication* *Research supported by MURST-PRIN “Robust Techniques for uncertain system…
2009
Abstract In this paper we discuss agents exchanging quantized flows to diverge one from the others according to a dissensus protocol. A Quantized Gossip algorithm is considered. Evolutions of the states during switching intervals and at switching instants and their property are described and analyzed. The modeling of switching systems describing networks where death and duplication processes occur is described. Some properties of the topology reached by the network when different rules of duplication and inheritance are implemented.
"Design and application of a data-independent precursor and product ion repository."
2012
The functional design and application of a data-independent LC-MS precursor and product ion repository for protein identification, quantification, and validation is conceptually described. The ion repository was constructed from the sequence search results of a broad range of discovery experiments investigating various tissue types of two closely related mammalian species. The relative high degree of similarity in protein complement, ion detection, and peptide and protein identification allows for the analysis of normalized precursor and product ion intensity values, as well as standardized retention times, creating a multidimensional/orthogonal queryable, qualitative, and quantitative spac…
El Prácticum de Ciencias Sociales en dos Universidades Iberoamericanas
2019
El artículo presenta un estudio comparativo de algunas de las percepciones que tienen futuros docentes de la Universitat de Valencia (Valencia-España) y Francisco José de Caldas (Bogotá-Colombia) sobre su desempeño docente. Las fuentes utilizadas para su análisis han sido los informes de las prácticas elaborados finalizada su intervención de aula. El trabajo se realiza desde una perspectiva cualitativa acudiendo al estudio de caso, que permite comprender un fenómeno de manera detallada. La formación inicial de profesores en didáctica de las ciencias sociales se ve influenciada por sus percepciones, que manifiestan diferencias entre las prácticas de aula y las teorías que se proponen en las …
Finite-dimensional pseudo-bosons: a non-Hermitian version of the truncated harmonic oscillator
2018
We propose a deformed version of the commutation rule introduced in 1967 by Buchdahl to describe a particular model of the truncated harmonic oscillator. The rule we consider is defined on a $N$-dimensional Hilbert space $\Hil_N$, and produces two biorhogonal bases of $\Hil_N$ which are eigenstates of the Hamiltonians $h=\frac{1}{2}(q^2+p^2)$, and of its adjoint $h^\dagger$. Here $q$ and $p$ are non-Hermitian operators obeying $[q,p]=i(\1-Nk)$, where $k$ is a suitable orthogonal projection operator. These eigenstates are connected by ladder operators constructed out of $q$, $p$, $q^\dagger$ and $p^\dagger$. Some examples are discussed.
Opinions about people with schizophrenia among medical students: Findings from an Italian cross-sectional study.
2020
Background: Accumulating evidence suggests that stigmatisation toward people with schizophrenia (PWS) is common among healthcare professionals and represents a major barrier to care. Aim: The study aimed at comparing the opinions about PWS among Italian medical students at different stages of education. Methods: Study participants were 234 medical students, attending either the first three-years pre-clinical or the following three-years clinical stage. Participants read an unlabelled case-vignette of schizophrenia and completed the Opinions on Mental Illness Questionnaire. Results: A greater proportion of students at the clinical stage identified schizophrenia in the clinical description, c…
