Geometric représentations of the braid groups
2010
We show that the morphisms from the braid group with n strands in the mapping class group of a surface with a possible non empty boundary, assuming that its genus is smaller or equal to n/2 are either cyclic morphisms (their images are cyclic groups), or transvections of monodromy morphisms (up to multiplication by an element in the centralizer of the image, the image of a standard generator of the braid group is a Dehn twist, and the images of two consecutive standard generators are two Dehn twists along two curves intersecting in one point). As a corollary, we determine the endomorphisms, the injective endomorphisms, the automorphisms and the outer automorphism group of the following grou…
A simple algorithm for finding short sigma-definite representatives
2010
We describe a new algorithm which for each braid returns a quasi-geodesic sigma-definite word representative, defined as a braid word in which the generator sigma_i with maximal index i appears either only positively or only negatively.
Pharmacogenomic identification of small molecules for lineage specific manipulation of subventricular zone germinal activity
2017
Strategies for promoting neural regeneration are hindered by the difficulty of manipulating desired neural fates in the brain without complex genetic methods. The subventricular zone (SVZ) is the largest germinal zone of the forebrain and is responsible for the lifelong generation of interneuron subtypes and oligodendrocytes. Here, we have performed a bioinformatics analysis of the transcriptome of dorsal and lateral SVZ in early postnatal mice, including neural stem cells (NSCs) and their immediate progenies, which generate distinct neural lineages. We identified multiple signaling pathways that trigger distinct downstream transcriptional networks to regulate the diversity of neural cells …
The role of intellectual capital and entrepreneurial characteristics as innovation drivers
2014
La innovacion y la iniciativa empresarial son estrategias organizacionales esenciales para encontrar una salida a la crisis mundial que afecta a las empresas de hoy en dia. Por lo tanto, el estudio de como los factores organizacionales como el capital intelectual o las caracteristicas de los empresarios afectan el exito de un proyecto empresarial innovador, es de gran importancia para ayudar a las organizaciones actuales a encontrar una solucion a este problema. El capital intelectual implica una inversion en capital humano, estructural y relacional. Por consiguiente, nuestro objetivo investigativo se centra en analizar la influencia del capital intelectual asi como las caracteristicas pers…
Review of Particle Physics
2020
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,143 new measurements from 709 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. Particle properties and search limits are listed in Summary Tables. We give numerous tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, …
USING THE METHOD OF NARRATIVE CHANGE ACCOUNTING IN THE RESEARCH OF A LARGE FOREST INDUSTRY COMPANY. POWER AND CHANGE IN FOCUS
2010
The aim of the study was to analyze the use of power in a strategic change process within a large forest industry company. The organization in question had a total of 7 700 employees, 6–8 organizational levels, over 30 production units and a widespread international sales network.

Precio no monetario percibido en alojamientos e-peer-to-peer. La perspectiva de los huéspedes de Airbnb
2021
[EN] Price is considered as a key variable in predicting buying behavior. However, few studies have focused on how non-monetary price is affected and can affect other components of the consumer endogenous variables. This paper seeks (1) to analyze the effects of antecedents of behavioural price (past experience, the benefits and risks of peer to peer accommodation services) on the guest perceived price, and (2) to determine the effect of this price and past experience on guest intentions. With a sample of 136 Airbnb guests and the use of SEM, results show that past experience, financial risk, and time risk influence the non-monetary perceived price. This price and past experience affect gue…
