This article addresses the stabilizability of a perturbed quintic defocusing Schr\"odinger equation in $\mathbb{R}^{3}$ at the $H^1$--energy level, considering the influence of a damping mechanism. More specifically, we establish a profile decomposit

Platform-based laborers face unprecedented challenges and working conditions that result from algorithmic opacity, insufficient data transparency, and unclear policies and regulations. The CSCW and HCI communities increasingly turn to worker data col

We investigate the relationship between smoothness and the relative global dimension. We prove that a smooth ring map $B\to A$ between commutative rings implies the finiteness of the relative global dimension $\operatorname{gldim}(A,B)$. Conversely,

This article deals with the $H^{1}$--level local null controllability for the defocusing critical nonlinear Schr\"{o}dinger equation in $\mathbb{R}^3$. Firstly, we show the problem under consideration to be well-posed using Strichartz estimates. More

We show how to deform a Poisson quasi-Nijenhuis manifold by means of a closed 2-form. Then we interpret this procedure in the context of quasi-Lie bialgebroids, as a particular case of the so called twisting of a quasi-Lie bialgebroid. Finally, we fr

Abstract Background Campylobacter spp. have been reported as a common cause of gastroenteritis in humans in many countries. However, in Brazil there is insufficient data to estimate the impact of Campylobacter in public health. In light of the import

Abstract In this study, friction stir processing (FSP) parameters were optimized using the response surface method (RSM) to enhance hardness, reduce the friction coefficient and minimize the corrosion rate in cast Al12Si and Al14Si alloys. The FSP to
