    Carolingian biblical exegesis presents itself as a synthesis of exegetical and theological patristic tradition in order to make it affordable to the Christians of that time. The result of that process are interpretations of biblical texts that can be considered new, though based on the texts of the Fathers. Among them it is possible to find images of the Church containing ideas about power or how to govern and to order society. This paper studies Haimo of Auxerre’s commentary on I Cor 12, 12 et seq in order to establish the author’s concept of ’body of Christ’, in the context of the Eucharistic controversy of the ninth century. It also studies the ideological consequences of his exegesis.Fil: Hernandez Rodriguez, Alfonso Maria. Consejo Nacional de Investigaciones Científicas y Técnicas.

    A probabilistic data-driven model for planar pushing

    Full text link
    This paper presents a data-driven approach to model planar pushing interaction to predict both the most likely outcome of a push and its expected variability. The learned models rely on a variation of Gaussian processes with input-dependent noise called Variational Heteroscedastic Gaussian processes (VHGP) that capture the mean and variance of a stochastic function. We show that we can learn accurate models that outperform analytical models after less than 100 samples and saturate in performance with less than 1000 samples. We validate the results against a collected dataset of repeated trajectories, and use the learned models to study questions such as the nature of the variability in pushing, and the validity of the quasi-static assumption.Comment: 8 pages, 11 figures, ICRA 201

    Bicycling Black Rings

    Full text link
    We present detailed physics analyses of two different 4+1-dimensional asymptotically flat vacuum black hole solutions with spin in two independent planes: the doubly spinning black ring and the bicycling black ring system ("bi-rings"). The latter is a new solution describing two concentric orthogonal rotating black rings which we construct using the inverse scattering technique. We focus particularly on extremal zero-temperature limits of the solutions. We construct the phase diagram of currently known zero-temperature vacuum black hole solutions with a single event horizon, and discuss the non-uniqueness introduced by more exotic black hole configurations such as bi-rings and multi-ring saturns.Comment: 32 pages, 12 figure

    Molecular dynamics simulations of Ibuprofen release from pH-gated silica nanochannels

    The iboprufen delivery process from cylindrical silica pores of diameter 3~nm, with polyamine chains anchored at the pore outlets,was investigated by means of massive molecular dynamics simulations. Effects from pH were introduced by considering polyamine chains with different degree of protonation. High, low and intermediate pH environments were investigated. The increment of the acidity of the environment leads to a significant decrease of the pore aperture,  yielding an effective diameter, for the lowest pH case, that is 3.5~times smaller than the one associated to the highest pH one. Using a biased sampling procedure, Gibbs free energy profiles for the ibuprofen delivery process were obtained. The joint analysis of the corresponding profiles, time evolution of the ibuprofen position within the channel, orientation of the molecule and instantaneous effective diameter of the gate, suggests a 3-steps mechanism for ibuprofen delivery. A complementary analysis of the translational mobility of ibuprofen along the axial direction of the channel revealed a sub-diffusive dynamics in the low and intermediate pH cases.Deviations from Brownian diffusive dynamics are discussed and compared with direct experimental results.

    Tactile Mapping and Localization from High-Resolution Tactile Imprints

    Full text link
    This work studies the problem of shape reconstruction and object localization using a vision-based tactile sensor, GelSlim. The main contributions are the recovery of local shapes from contact, an approach to reconstruct the tactile shape of objects from tactile imprints, and an accurate method for object localization of previously reconstructed objects. The algorithms can be applied to a large variety of 3D objects and provide accurate tactile feedback for in-hand manipulation. Results show that by exploiting the dense tactile information we can reconstruct the shape of objects with high accuracy and do on-line object identification and localization, opening the door to reactive manipulation guided by tactile sensing. We provide videos and supplemental information in the project's website http://web.mit.edu/mcube/research/tactile_localization.html.Comment: ICRA 2019, 7 pages, 7 figures.

    The Contemporary Human Resources Function

    Get PDF
    Abstract Current companies encounter important challenges day to day. Many factors such as the economic globalization, the change in the way of working, the Internet boom, and the importance that the service sector is experiencing nowadays influence the new society in which persons and businesses actually cope. Each of these contingencies obligates the Human Resource function to adapt to new organizational goals moulding their strategies and tactics to the in fashion topics. In this work we present the classical functions integrated in the Human Resources department constituting its base of performance. We also deal equally with the high performance practices and the importance that is acquiring the binomial human resources management strategies – business performance such as new tendencies applicable in this area.Universidad de Málaga.

    Family functioning characteristics involved in adolescent depressive symptoms

    Get PDF
    Research has shown that family functioning contributes to depressive symptoms in adolescents, with a wide range of family functioning characteristics associated to adolescent depressive symptoms. However, these family attributes have been studied through different studies, methodologies and theoretical frameworks, and do not allow envisaging a single whole picture of the family attributes associated to adolescent depressive symptoms. The objective of this study was to overcome this deficit. We followed a systematic approach and used the Family Assessment Device (FAD), which comprehensively identify six family variables in which healthy and unhealthy families differ: Problem Solving (PS), Communication (CM), Roles (RL), Affective Responsiveness (AR), Affective Involvement (AI) and Behaviour Control (BC). Independent regression analyses conducted for each variable showed that all the FAD variables significantly predicted BDI scores. However, when the six variables were introduced simultaneously in the same equation to control for the shared explained variance, only AR and AI showed significant effects, with BC approaching significance. These results were confirmed through Prat measure, which showed that the non-overlapping effects of AR, AI and BC accounted for virtually the whole variance explained by the FAD dimensions. Conclusions at both methodological and applied levels emerge from these results. At a methodological level, these results prove the need for controlling the shared variance between family variables before deriving any conclusion about their role. At an applied level, they showed that the family affective aspects are the most important regarding adolescent depression, with only behaviour control playing a role within the non-affective variables.Universidad de Málaga.
