Multi-Dimensional motivic pattern extraction founded on adaptive redundancy filtering
2005
Abstract We present a computational model for discovering repeated patterns in symbolic representations of monodic music. Patterns are discovered through an incremental adaptive identification along a multi-dimensional parametric space. The difficulties of pattern discovery mainly come from combinatorial redundancies, that our model is able to control efficiently. A specificity relation is defined between pattern descriptions, unifying suffix and inclusion relations and enabling a filtering of redundant descriptions. Combinatorial proliferation caused by successive repetitions of patterns is managed using cyclic patterns. The modelling of these redundancy control mechanisms enables an autom…
La ontología de la proposición en el Russell de "The Principles of Mathematics" y los artículos de Meinong
2005
Bertrand Russell, in The Principles of Mathematics and ¿Meinong¿s Theory of Complexes and Assumptions¿, maintains a unitary conception of the ontology of propositions. He makes a difference between judgment and proposition. Propositions are independent entities and they have different presentations. False propositions subsist; this is related to the relation in the proposition called ¿affirmation¿ and the double condition of predicates (meaning and term). But that conception has bad consequences for the unity and identity of proposition.
La forma de los entes matemáticos en The Principles of Mathematics de Bertrand Russell.
2011
The critic against subject-predicate propositions is a Russell's feature. See for example A Critical Exposition of the Philosophy of Leibniz. However, in The Principles of Mathematics Russell goes back to the subject-predicate form but in the context of his contribuition to the development of Modern Logic and his philosophy of mathematics
Lógicas epistémicas y sistemas multiagentes: los agentes nacen y mueren
2008
In this paper we study the propositional epistemic logics with operators to analize the knowledge of a group, and its applications to the multi-agent systems when the number of agents can vary between different worlds or states.
ASSET MARKETS AND EQUILIBRIUM SELECTION IN PUBLIC GOODS GAMES WITH PROVISION POINTS: AN EXPERIMENTAL STUDY
2001
We report experimental results on the effects that auctioning the right to play a public goods game with a provision point may have on equilibrium selection and individual behavior. Auctioning off such a right among a larger population of players strikingly enhances public good provision. Once public good provision is obtained, the auction price at the preliminary stage increases to its upper limit, dissipating all players’ gains associated with the provision of the public good. Individual deviations from the equilibrium strategy are neither able to force lower market prices nor to affect provision of the public good in subsequent periods. (JEL C72, C92, H41) I. INTRODUCTION Public good pro…

Coordination Driven Capture of Nicotine Inside a Mesoporous MOF.
2017
Metal organic frameworks (MOFs) are a wide class of crystalline porous polymers studied in many fields, ranging from catalysis to gas storage. In the past few years, MOFs have been studied for the encapsulation of organic or organometallic molecules and for the development of potential drug carriers. Here, we report on the study of two structurally-related mesoporous Cu-MOFs, namely PCN-6 and PCN-6′ (PCN stands for Porous Coordination Network), for nicotine trapping. Nicotine is a well-known alkaloid liquid molecule at room temperature, whose crystalline structure is still unknown. In this work, the loading process was monitored by electron ionization mass spectrometry by using a direct ins…
First Principles Calculations of Atomic and Electronic Structure of TiAl3+- and TiAl2+-Doped YAlO3
2021
In this paper, the density functional theory accompanied with linear combination of atomic orbitals (LCAO) method is applied to study the atomic and electronic structure of the Ti3+ and Ti2+ ions substituted for the host Al atom in orthorhombic Pbnm bulk YAlO3 crystals. The disordered crystalline structure of YAlO3 was modelled in a large supercell containing 160 atoms, allowing simulation of a substitutional dopant with a concentration of about 3%. In the case of the Ti2+-doped YAlO3, compensated F-center (oxygen vacancy with two trapped electrons) is inserted close to the Ti to make the unit cell neutral. Changes of the interatomic distances and angles between the chemical bonds in the de…
The what, when, where, and how of visual word recognition
2014
A long-standing debate in reading research is whether printed words are perceived in a feedforward manner on the basis of orthographic information, with other representations such as semantics and phonology activated subsequently, or whether the system is fully interactive and feedback from these representations shapes early visual word recognition. We review recent evidence from behavioral, functional magnetic resonance imaging, electroencephalography, magnetoencephalography, and biologically plausible connectionist modeling approaches, focusing on how each approach provides insight into the temporal flow of information in the lexical system. We conclude that, consistent with interactive a…
Functional Brain Segmentation Using Inter-Subject Correlation in fMRI
2016
The human brain continuously processes massive amounts of rich sensory information. To better understand such highly complex brain processes, modern neuroimaging studies are increasingly utilizing experimental setups that better mimic daily‐life situations. A new exploratory data‐analysis approach, functional segmentation inter‐subject correlation analysis (FuSeISC), was proposed to facilitate the analysis of functional magnetic resonance (fMRI) data sets collected in these experiments. The method provides a new type of functional segmentation of brain areas, not only characterizing areas that display similar processing across subjects but also areas in which processing across subjects is h…
