Distribución espacial de impactos de eventos hidrometeorológicos en América Central
(2016)
América Central está expuesta a la ocurrencia de eventos hidrometeorológicos a lo largo del año y los impactos que estos pueden provocar van a estar mayormente localizados en áreas donde las variables tanto naturales como ...
Fermi-LAT detection of G118.4+37.0: a supernova remnant in the Galactic halo seen around the Calvera pulsar
(2023)
The discovery of a non-thermal radio ring of low surface brightness about one degree in diameter has been recently reported around the location in the sky of the Calvera pulsar, at a high Galactic latitude. The radio ...
Interaction of a quantum field with a rotating heat bath
(2018-08-01)
The linear coupling of a rotating heat bath to a quantum field is studied in the framework of the Markovian master equation for the field's non-unitary time evolution. The bath's rotation induces population inversion for ...
The problem of engines in statistical physics
(2021-08-22)
Engines are open systems that can generate work cyclically at the expense of an external disequilibrium. They are ubiquitous in nature and technology, but the course of mathematical physics over the last 300 years has ...
Física y Poesía: T.S. Eliot
(1992)
Tres poemas de T.S. ELIOT, publicados en 1989, sugieren que el autor tenía conocimientos tanto de física clásica como de física moderna.
En este artículo se describen los conceptos físicos tratados y se hace referencia ...
The Josephson junction as a quantum engine
(2023-11-10)
We treat the Cooper pairs in the superconducting electrodes of a Josephson junction (JJ) as an open system, coupled via Andreev scattering to external baths of electrons. The disequilibrium between the baths generates the ...
Phototransport Properties of a-SiC:H Alloys
(1995)
We report a study of the mobility-lifetime products of the two charge carriers in a-SiC:H alloys. The measurements were carried out as a function of the carbon concentration and the temperature. An analysis, relying on the ...
Evaluation of [18F] FNM biodistribution and dosimetry based on whole-body PET imaging of rats
(2018)
Introduction: The aim of this work was to study the biodistribution, metabolism and radiation dosimetry of rats
injected with [18F]FNM using PET/CT images. This novel radiotracer targeting NMDA receptor has potential ...
Probing the origin of 4FGL J0822.8–4207: cosmic ray illumination from the SNR Puppis A and the Herbig-Haro object HH219
(2021)
4FGL J0822.8–4207 is a point source found in the 4FGL-DR2 catalogue by the gamma-ray observatory Fermi-LAT and has no known association. We carry out X-ray observations of 4FGL J0822.8–4207 to help understand its nature. ...
