Democracia y opinión pública. El desafío político de la modernidad, escrito por Rubén de Jesús Ibarra Reyes y Elizabeth Amador Márquez, publicado en 2018 en coedición por la prolífica Universidad Autónoma de Zacatecas (UAZ) y la Editorial Ítaca, constituye, sin duda, una obra por demás pertinente que llega a enriquecer el debate político en México y América Latina en un tiempo crucial de transición

An extended model of currency options applicable as policy tool for central banks with inflation targeting and dollarized economies

The purpose of this paper is to provide a new set of tools for policy makers at central banks. Based on the Garman-Kohlhagen formula for currency options, this research extends it with the Taylor-rule expression used for inflation targeting, thus obtaining the corresponding Call and Put options and higher-degree partial derivatives known as "Greeks" for key variables such as the policy target domestic interest rate and the output gap

A new formulation of heat dissipation in a rocking Büttiker-Landauer ratchet model

Thermal ratchets achieve net particle transport through recti cation of thermal uctuations, which arise from one or more heat baths in the system. We propose a new formulation of heat dissipation from the ratchet to the thermal baths, using a rocking Büttiker-Landauer ratchet model. We found that heat transport between the ratchet and the heat baths is related to the effective temperature through the generalization of the uctuation-dissipation theorem for systems far from equilibrium. We showed that the net heat transport between the ratchet and the heat baths is different from Fourier's law and is the sum of two terms which are proportional to the nth power of the difference between the effective temperature of ratchet and the temperature of the baths. The power n depends only on the temperature of the bath, while the thermal conductivity also depends on the ratchet potential. These ndings suggest that anomalous heat dissipation can be a non-equilibrium measure for systems far from equilibrium.Fil: Mazzitello, Karina Irma. Universidad Nacional de Mar del Plata.

Pyroelectric Trapping and Arrangement of Nanoparticles in Lithium Niobate Opposite Domain Structures

The particular ferroelectric domain structure of periodic opposite domain lithium niobate (ODLN) crystals has been used for the first time for structured nanoparticle trapping. The surface charge density produced by a temperature change in this pyroelectric material is the origin of the trapping forces: dielectrophoretic on neutral particles and electrophoretic on charged ones. Metallic and dielectric particles are trapped and structured. The results show that ODLN structures are efficient substrates for pyroelectric trapping. The different trapping behaviors are presentedThis work has been supported by the Spanish Ministerio de Economía y Competitividad under grant ref.: MAT2014-57704-C3-1-
