Previously published treatment is rather involved. Here we present a useful approximation to the concomitant derivation that yields a simpler way of handling things and still obtains results quite similar to those yielde...

Graphene layers are known to stack in two stable configurations, namely, ABA or ABC stacking, with drastically distinct electronic properties. Unlike the ABA stacking, little has been done to experimentally investigate t...

Old fields are spreading in the world because of agriculture abandonment, and they show a persistence of exotic plant species with little recovery towards the original vegetation composition. Soil biota may also differ b...

Agricultural intensification simplified environments, reduced their diversity, and hindered their ecosystem processes. Permanently vegetated areas (uncultivated margins) embedded in the cultivated matrix play a critical ...

The choice of sampling method is essential in the development of a population genetic study. This choice influences the type of samples that can be obtained and, therefore, the quality of the extracted DNA. Sampling meth...

Using recent spectroscopic observations, we show that the triple system AO Vel with an eclipsing BpSi primary is in fact a remarkable quadruple system formed by two double-lined spectroscopic binaries with components clo...

We study a single class of traffic acting on a symmetric set of processor-sharing queues with finite buffers, and we consider the case where the load scales with the number of servers. We address the problem of giving ro...

Puccinia sorghi Schwein., the causal agent of maize common rust, is an endemic disease in the Argentine Corn Belt region. Virulence surveys of the pathogen population within the region have not been performed; thus, the ...

We compute the contact term of the two-point function for the SL (2, ℝ)- WZNW model in the winding sector. After reviewing some generalities of the model and its Euclidean counterpart, we discuss the reflection symmetr...

In this paper, the Author presents the semantic and methodological scope and characteristics of a new field the archaeology of the contemporary past. In his opinion the essence of the archaeology of the contemporary past...

The article highlights the problem of realization of interdisciplinary connections in the process of preparation of future primary school teachers and educators of preschool educational institutions. The emphasis is plac...

The strength of species interactions influences strongly the structure and dynamics of ecological systems. Thus, quantifying such strength is crucial to understand how species interactions shape communities and ecosystem...

The Andes Cordillera contains the most diverse cryosphere on Earth, including extensive areas covered by seasonal snow, numerous tropical and extratropical glaciers, and many mountain permafrost landforms. Here, we revie...

Lead zirconate titanate (PZT) has long been regarded as the gold standard material for piezoelectric sensorsowing to its outstanding piezoelectric performance (d33 = 500–600 pC/N) and well-established industrial scalab...

A quantitative interpretation of the schlieren technique applied to a non-thermal atmospheric-pressure oxygen plasma jet driven at low-frequency (50 Hz) is reported. The jet was operated in the turbulent regime with a ho...

La Formación Chenque (Mioceno Inferior-Medio) en la cuenca del Golfo San Jorge representa los depósitos de un evento transgresivo atlántico con evidencias mesoscópicas de tectónica extensional. Se presentan los resu...

El trabajo aborda la temática de las perspectivas metodológicas cuantitativas en el campo de estudio sobre el conflicto social en la historia argentina reciente. Lo hace a partir de la presentación del diseño de una ...

Axionlike particles (ALPs) are hypothetical light (sub-eV) bosons predicted in some extensions of the Standard Model of particle physics. In astrophysical environments comprising high-energy gamma rays and turbulent magn...

A set of coupled Brownian motors—resulting from a noise-induced phase transition generated through an entropic mechanism, and formerly studied in mean-field approximation—is numerically integrated by Heun’s method....

En este artículo me baso en un trabajo de campo realizado en las tierras de una gran propiedad rural del Nordeste de Brasil, hoy desaparecida. Parto de la historia sobre dicha propiedad que me cuentan antiguos habitante...

El presente artículo de investigación consiste en una elaboración en clave teórica de los principales debates y aportes respecto del Estado y las políticas públicas. A partir de una serie de problemáticas que obse...

We study the entanglement harvesting between two identical buckled honeycomb lattices placed inside a planar microcavity. By applying time dependent perturbation theory, we obtain quantum correlations between both layers...

Las políticas educativas como objeto de estudio presentan desafíos a los investigadores del area. Concebida tradicionalmente como normas y regulaciones elaboradas por especialistas y aplicadas por las instituciones, ...
