An upscattering spectral formation model for the prompt emission of Gamma-Ray Bursts
We propose a model for the spectral formation of Gamma Ray Burst (GRB) prompt emission, where the phenomenological Band's function is usually applied to describe the GRB prompt emission.

Benzene, an Unexpected Binding Unit in Anion–π Recognition: The Critical Role of CH/π Interactions
We report high-level ab initio calculations (CCSD(T)(full)/CBS//SCS-RI-MP2(full)/aug-cc-pwCVTZ) that demonstrate the importance of cooperativity effects when Anion–π and CH/π interactions are simultaneously established with benzene as the π-system.

Average power density spectrum of long GRBs detected with BeppoSAX/GRBM and with Fermi/GBM
From past experiments the average power density spectrum (PDS) of GRBs with unknown redshift was found to be modelled from 0.01 to 1 Hz with a power-law, f^(-alpha), with alpha broadly consistent with 5/3.

Las lógicas de gobierno de lo fronterizo en el espacio Schengen: la frontera como estriación
Este artículo propone una reflexión sobre la frontera considerando su operatividad como espacio de gobierno. Esta lectura implica trascender el ingrediente territorial de frontera –y su sentido de afirmación soberana– y atender a su funcionalidad ...

Unprecedented application of X‐ray photoelectron spectroscopy (XPS) for quantifying halogen and chalcogen bond strengths. This pioneering work provides the first benchmark study and establishes strong correlations between XPS shifts (ΔBE) and interaction energies (ΔE), revealing XPS as an experimental measure for noncovalent bond quantification in ...

The objective of this paper is to analyze the extent to which Mexican migration policy has made Mexico an extensive border for irregular migrants in transit to the United States, the so-called "vertical border." To this end, it examines Mexican control ...
