In this work we search for boundedness results for operators related to the semigroup generated by the degenerate Schrödinger operator Lu=−1ωdivA⋅∇u+Vu, where ω is a weight, A is a matrix depending on x and sati...

This study is based on a comparative and contrastive analysis of a hetero-semiotic pair: Guy de Maupassant’s short story Boule de Suif and its graphic novel adaptation by Li-An, published by Delcourt in 2009. The centr...

When two nonorthogonal resonances are coupled to the same radiation channel, avoided crossing arises and a bound state in the continuum (BIC) appears with appropriate conditions in parametric space. This paper presents n...

Photonic bound states in the continuum (BICs) are eigenmodes with an infinite lifetime, which coexist with a continuous spectrum of radiating waves. BICs are not only of great theoretical interest but also have a wide ra...

We study the impact of structural disorder on a radiative lifetime of symmetry-protected bound state in the continuum (BIC) and a bright mode in a one-dimensional periodic chain of coupled Mie resonators. Through experim...

A model for computing acoustic scattering by swimbladdered fish is presented. The effect of acoustic coupling between the fish tissue and the swimbladder is included. The swimbladder is considered a gas-filled object whe...

A obra do sociólogo francês Raymond Boudon é analisada sob a perspectiva da relação agência e estrutura. Argumenta-se que a possibilidade de síntese entre agência e estrutura está ligada à combinação de uma c...

In this work we address the classical statistical mechanical problem of calculating the residual entropy of ice models. The numerical work found in the literature is usually based on extrapolating to infinite-size result...

This is the first of two chapters of a work in which we consider the unrestricted, minimal, and bounded representation problems for unit interval (UIG) and unit circular-arc (UCA) graphs. In the unrestricted version, a p...

Resumo O alcance e a envergadura dos trabalhos de Pierre Bourdieu são atestados ao redor do mundo desde suas primeiras publicações na década de 1960, passando pelas traduções que suas obras receberam ao longo do te...

A non-boundary conforming formulation for simulating complex flows with moving solid boundaries on fixed Cartesian grids is proposed. The direct forcing immersed boundary method (IBM) is implemented in a direct numerical...

This paper analyzes the day-to-day adjustment process of users’ behaviors in a transport network which is affected by relevant alterations such as disruptions due to critical events which cause the impossibility to use...

In Thailand’s Deep South, insurgency remains an urgent issue which has not been resolved since 2004. Muslim cultural resistance in Thailand’s Deep South is rooted in resentment from state-driven assimilation, which h...

Abstract This article analyses the Bolsonaro government’s foreign policy and the interests of the Brazilian internal bourgeoisie. The hypothesis is that the internal bourgeoisie supported the 2016 coup d’état and th...

The Deep Western Boundary Current (DWBC) at 34.5° S in the South Atlantic carries a significant fraction of the cold deep limb of the Meridional Overturning Circulation (MOC), and therefore its variability affects the m...

Abstract This study characterizes the seasonal variations and cross-boundary aerosol transport in central Thailand using a combination of low-cost PM2.5 sensors, sunphotometer observations, and Himawari-9 satellite aeros...

O Brasil foi um dos casos pioneiros na recepção internacional de Pierre Bourdieu, sociólogo que, desde a década de 1990, tornou-se um dos mais citados em todo o país. Essa questão é discutida articulando-se duas s...

We investigate whether a dynamical wormhole could survive in a universe that undergoes a cosmological bounce. First, the conditions under which a wormhole could persist from a contracting to an expanding phase of the cos...

Nonlinear optics has generated a wide range of applications in the fields of optical communications, biomedicine, and materials science, with nonlinear conversion efficiency serving as a vital metric for its progress. Ho...

ABSTRACT In this study, the erosion of the nocturnal boundary layer (NBL) was analyzed in the central Amazon during the dry season of 2014, using data from the GoAmazon 2014/5 Project and high-resolution model outputs (P...

Abstract In this paper we investigate the existence and approximation solution for nonlinear system of an integro-differential equation of the second order with boundary conditions by using the numerical-analytic method ...

Parameter calibration of the traffic assignment models is vital to travel demand analysis and management. As an extension of the conventional traffic assignment, boundedly rational activity-travel assignment (BR-ATA) com...

Abstract This paper investigates the initial-boundary value problem for quasilinear strictly hyperbolic systems of diagonal form with characteristics which are partially linearly degenerate and partially weakly linearly ...

We initiate the study of graph classes of power-bounded clique-width, that is, graph classes for which there exist integers k and ℓ such that the kth powers of the graphs are of clique-width at most ℓ. We give suffic...
