28 p, 1.7 MB Conventional and Non-Conventional Roles of Non-Muscle Myosin II-Actin in Neuronal Development and Degeneration / Javier, Miriam (Universitat Autònoma de Barcelona. Institut de Neurociències) ; Saura Antolín, Carlos A. (Carlos Alberto) (Universitat Autònoma de Barcelona. Departament de Bioquímica i Biologia Molecular)
Myosins are motor proteins that use chemical energy to produce mechanical forces driving actin cytoskeletal dynamics. In the brain, the conventional non-muscle myosin II (NMII) regulates actin filament cytoskeletal assembly and contractile forces during structural remodeling of axons and dendrites, contributing to morphology, polarization, and migration of neurons during brain development.

5 p, 445.5 KB Piezoelectric Mimicry of Flexoelectricity / Abdollahi, Amir (Universitat Politècnica de Catalunya) ; Vásquez Sancho, Fabián (Institut Català de Nanociència i Nanotecnologia) ; Catalan, Gustau (Institut Català de Nanociència i Nanotecnologia)
The origin of "giant" flexoelectricity, orders of magnitude larger than theoretically predicted, yet frequently observed, is under intense scrutiny. There is mounting evidence correlating giant flexoelectriclike effects with parasitic piezoelectricity, but it is not clear how piezoelectricity (polarization generated by strain) manages to imitate flexoelectricity (polarization generated by strain gradient) in typical beam-bending experiments, since in a bent beam the net strain is zero.

22 p, 93.0 KB El impacto de la Renta Básica sobre los incentivos laborales / Tena Sánchez, Jordi (Universitat Autònoma de Barcelona)
En el presente trabajo se discute el posible impacto de la introducción de una renta básica de ciudadanía (rb) sobre los incentivos laborales de los individuos, en particular de los segmentos de trabajadores precarios poco cualificados. [...]
This paper discusses the likely impact of the introduction of a Citizens' Basic Income on job incentives, in particular for the case of the more precarious and less skilled workers. The article argues that it is reasonable to expect that basic income would not produce a massive retreat from the labor market but, rather, a higher distribution of job. [...]

One of the main strategies to control magnetism by voltage is the use of magnetostrictive-piezoelectric hybrid materials, such as ferromagnetic-ferroelectric heterostructures. When such heterostructures are subjected to an electric field, piezostrain-mediated effects, electronic charging, and voltage-driven oxygen migration (magnetoionics) may simultaneously occur, making the interpretation of the magnetoelectric effects not straightforward and often leading to misconceptions.

32 p, 765.1 KB Income and social polarization : theoretical approaches / Permanyer, Iñaki (Universitat Autònoma de Barcelona. Centre d'Estudis Demogràfics)
The concept of polarization is related to the clustering of individuals forming groups in different parts of a given distribution. The existing relationship between polarization, socioeconomic stability and economic growth has contributed to motivating the interest in the study of polarization. [...]

44 p, 1.7 MB Spatial Polarization of the Ecological Footprint distribution / Teixidó-Figueras, Jordi ; Duro Moreno, Juan Antonio ; Xarxa de Referència en Economia Aplicada (XREAP)
The international allocation of natural resources is determined, not by any ethical or ecological criteria, but by the dominance of market mechanisms. From a core-periphery perspective, this allocation may even be driven by historically determined structural patterns, with a core group of countries whose consumption appropriates most available natural resources, and another group, having low natural resource consumption, which plays a peripheral role.

Facultat de Ciències Polítiques i de Sociologia
It is often argued whether the American electorate is in a period of polarization (Abramowitz 2010), partisan sorting (Fiorina & Abrams 2009), or geographic clustering; and what might be the causes of these observations. [...]
