El intercambio comunicacional que se produce entre los movimientos sociales y diversos actores políticos a través de los medios ha sido estudiado a partir de los frames, marcos o encuadres (Gamson, 2001). El proceso por ...

Es posible rastrear la presencia de las drogas en innumerables culturas a lo largo de la historia humana. Las tribus nos enseñan que el uso ritual de la droga puede cumplir una función relevante para la cohesión de la ...

Out of equilibrium systems under the influence of enough energy injection exhibit complex spatiotemporal behaviors. Based on a liquid crystal light valve experiment with translational optical feedback, we observe propagation, ...

In galactic disks, galactic rotation sets the bulk motion of gas, and its energy and momentum can be transferred toward small scales. Additionally, in the interstellar medium, random and noncircular motions arise from ...

Two-dimensional arrays of coupled waveguides or coupled microcavities allow us to confine and manipulate light. Based on a paradigmatic envelope equation, we show that these devices, subject to a coherent optical injection, ...

Introduction Improvements in technology and health care have helped reduce morbidity and mortality in patients with esophageal atresia. However, postoperative complications such as dehiscences, strictures, and recurrent ...

Geostatistical tools have become the standard for characterizing the spatial distribution of geological subsurface structures. However, the problem of image recovery for regimes with low acquisition rates still poses a ...

Triassic orthogneisses of the Antarctic Peninsula provide evidence for the Palaeozoic and Mesozoic geological evolution of southern Gondwana within Pangaea. These rocks are sporadically exposed in southeastern Graham Land ...

Zinc finger protein SNAI1 (SNAIL) and zinc finger protein SNAI2 (SLUG) transcription factors promote epithelial-mesenchymal transition, a process through which epithelial cells acquire a mesenchymal phenotype, increasing ...
