Distributed and proximity-constrained C-means for discrete coverage control
2018
In this paper we present a novel distributed coverage control framework for a network of mobile agents, in charge of covering a finite set of points of interest (PoI), such as people in danger, geographically dispersed equipment or environmental landmarks. The proposed algorithm is inspired by C-Means, an unsupervised learning algorithm originally proposed for non-exclusive clustering and for identification of cluster centroids from a set of observations. To cope with the agents' limited sensing range and avoid infeasible coverage solutions, traditional C-Means needs to be enhanced with proximity constraints, ensuring that each agent takes into account only neighboring PoIs. The proposed co…
Adaptive learning of compressible strings
2020
Suppose an oracle knows a string $S$ that is unknown to us and that we want to determine. The oracle can answer queries of the form "Is $s$ a substring of $S$?". In 1995, Skiena and Sundaram showed that, in the worst case, any algorithm needs to ask the oracle $\sigma n/4 -O(n)$ queries in order to be able to reconstruct the hidden string, where $\sigma$ is the size of the alphabet of $S$ and $n$ its length, and gave an algorithm that spends $(\sigma-1)n+O(\sigma \sqrt{n})$ queries to reconstruct $S$. The main contribution of our paper is to improve the above upper-bound in the context where the string is compressible. We first present a universal algorithm that, given a (computable) compre…

School choice criteria and school segregation in the city of Valencia
2022
El objetivo de este estudio es conocer cuáles son los patrones que intervienen en la elección de centro escolar y detectar los factores sociodemográficos, económicos y de localización que subyacen tras ellos. Para ello, se ha realizado una encuesta a la demanda potencial de los centros públicos que imparten el segundo ciclo de educación infantil en la ciudad de Valencia. Los resultados indican que el principal criterio de elección de centro escolar es la proximidad entre el hogar y el colegio, y que el modo de desplazamiento más utilizado es el peatonal. Sin embargo, los costes de desplazamiento y los medios utilizados están directamente relacionados con las características socioeconómicas …
Implementing the 5-S quality system at a State Vocational Training School
2013
El Método de las 5S Trata de lograr v Lugares de Trabajo mejor Organizados, Más ordenados y Más limpios de forma permanente CONSEGUIR Para Una alcaldesa productivity y entorno laboral Seguro. Este Trabajo describen las Fases de la Implantación del Método en el laboratorio de Hematología, En un centro educativo de Formación Profesional de la provincia de Valencia. Los Resultados obtenidos a posteriori de la Implantación del Método 5S, demuestran Una gran difference en Cuanto al orden, La ubicación de los Materiales y el mejor clima en el aula, en comparacion con los Resultados de la prueba piloto los antes de su Implantación. The 5S method try to make workplaces better organized, more orderl…

Ofd1, a Human Disease Gene, Regulates the Length and Distal Structure of Centrioles
2010
SUMMARYCentrosomes and their component centrioles represent the principal microtubule organizing centers of animal cells. Here we show that the gene underlying Orofaciodigital Syndrome 1, Ofd1, is a component of the distal centriole that controls centriole length. In the absence of Ofd1, distal regions of centrioles, but not procentrioles, elongate abnormally. These long centrioles are structurally similar to normal centrioles, but contain destabilized microtubules with abnormal post-translational modifications. Ofd1 is also important for centriole distal appendage formation and centriolar recruitment of the intraflagellar transport protein Ift88. To model OFD1 Syndrome in embryonic stem ce…
ANALISI FUNZIONALE DI GENI REGOLATORI DELLO SVILUPPO EMBRIONALE DI PARACENTROTUS LIVIDUS
2012
Parole chiave: TRIM, E3-ubiquitina ligasi, ectoderma orale, scheletogenesi, riccio di mare. La recente acquisizione di consistenti dati genomici ha confermato che organismi bilateri, semplici come i nematodi o complessi come l’uomo, fanno uso degli stessi strumenti di base, quali fattori di trascrizione e molecole segnale, per decodificare le informazioni necessarie allo sviluppo embrionale. Nel contesto di tali regolatori, la famiglia di proteine TRIM/RBCC (Tripartite motif/RING-Bbox-Coiled coil) rappresenta una delle principali classi di E3 ubiquitina ligasi putative, che svolgono ruoli essenziali nella regolazione di processi quali ciclo cellulare e sviluppo embrionale. Nel genoma di ric…
Roles for ELMOD2 and Rootletin in ciliogenesis.
2021
AbstractELMOD2 is a GTPase activating protein (GAP) with uniquely broad specificity for ARF family GTPases. We previously showed that it acts with ARL2 in mitochondrial fusion and microtubule stability and with ARF6 during cytokinesis. Mouse embryonic fibroblasts deleted for ELMOD2 also displayed changes in cilia related processes including increased ciliation, multiciliation, ciliary morphology, ciliary signaling, centrin accumulation inside cilia, and loss of rootlets at centrosomes with loss of centrosome cohesion. Increasing ARL2 activity or overexpressing Rootletin reversed these defects, revealing close functional links between the three proteins. This was further supported by the fin…
