The τ-fixed point property for left reversible semigroups
(Springer Open, 2015-12)
In this article we use the generalized Gossez-Lami Dozo property and the Opial condition to study the fixed point property for left reversible semigroups in separable Banach spaces. As a consequence, some previous results ...

Dark lattice solitons in one-dimensional waveguide arrays with defocusing saturable nonlinearity and alternating couplings
(2012)
In the present work, we examine “binary” waveguide arrays, where the coupling between adjacent sites alternates between two distinct values C1 and C2 and a saturable nonlinearity is present on each site. Motivated by ...

El giro dinámico en la epistemología formal: el caso del razonamiento explicativo
(Universidad del País Vasco, 2014)
We explore the possibilities that dynamic epistemic logic offers to model abductive reasoning. We show that many of the problems with formal approaches to abduction based on classical logic can be solved when considering ...

Immunohistochemical assessment of Pax8 expression during pancreatic islet development and in human neuroendocrine tumors
(Springer Verlag, 2011)
The paired box transcription factor Pax8 is critical for development of the eye, thyroid gland as well as the urinary and reproductive organs. In adult, Pax8 overexpression is associated with kidney, ovarian and thyroid ...

A Tool for Web Links Prototyping
(CSREA Press, 2011)
Crawlers for Virtual Integration processes must be efficient, given that VI process is online, which means that while the system is looking for the required information, the user is waiting for a response. Therefore, ...

Photovoice as a research-intervention tool for youth neighborhood activism in societally vulnerable contexts
(Global Journal of Community Psychology Practice Editorial Board, 2016)
Teenagers who live in vulnerable neighborhoods have a higher probability of entering into a vicious circle where they suffer the consequences of an unfair structure and, at the same time, contribute to the maintenance of ...

Computation of Ramsey Numbers by P Systems with Active Membranes
(World Scientific, 2011)
Ramsey numbers deal with conditions when a combinatorial object necessarily contains some smaller given objects. It is well known that it is very difficult to obtain the values of Ramsey numbers. In this work, a theoretical ...

On scalable spiking convnet hardware for cortex-like visual sensory processing systems
(IEEE Computer Society, 2010)
This paper summarizes how Convolutional Neural Networks (ConvNets) can be implemented in hardware using Spiking neural network Address-Event-Representation (AER) technology, for sophisticated pattern and object recognition ...

Use of Urea and Ammonia to Produce High-Strength PM Aluminium Parts
(European Powder Metallurgy Association (EPMA), 2011)
Two methods to obtain bulk nanostructured aluminium parts are compared. The first one consists on milling Al powder in an ammonia gas atmosphere. In the second method, the Al powder is milled in vacuum with the addition ...
