Three Solutions for Fourth-Order Impulsive Differential Inclusions via Nonsmooth Critical Point Theory

open access: yesJournal of Function Spaces, 2018
An existence of at least three solutions for a fourth-order impulsive differential inclusion will be obtained by applying a nonsmooth version of a three-critical-point theorem. Our results generalize and improve some known results.

Physical education and critical theory: approaches from the approach critical-emancipatory and teaching comunicativa

open access: yesRevista Ibero-Americana de Estudos em Educação, 2016
This article is in an effort to summarize the main features of social theory, referred to as Critical Theory, theoretical approach known by the Traditional Theory critical, especially as it is situated as a critical stance against capitalist society in ...

Holographic entanglement of purification near a critical point

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
In the presence of finite chemical potential $$\mu $$ μ , we holographically compute the entanglement of purification in a $$2+1$$ 2 + 1 - and $$3+1$$ 3 + 1 -dimensional field theory and also in a $$3+1$$ 3 + 1 -dimensional field theory with a critical ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes

open access: yesFEBS Letters, EarlyView.
The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

Gas-liquid critical point of the ultrasoft restricted primitive model from analytic theory

open access: yesCondensed Matter Physics, 2015
Gas-liquid criticality in the ultrasoft restricted primitive model (URPM) of polyelectrolytes is studied using the collective variables-based theory. For the model, an effective Hamiltonian is derived and explicit expressions for all the coefficients are

Gap solitons in periodic difference equations with sign-changing saturable nonlinearity

open access: yesAIMS Mathematics, 2022
In this paper, we consider the existence of gap solitons for a class of difference equations: $ \begin{equation*} Lu_{n}-\omega u_{n} = f_{n}(u_{n}), n\in\mathbb{Z}, \end{equation*} $ where $ Lu_{n} = a_{n}u_{n+1}+a_{n-1}u_{n-1}+b_{n}u_{n} $ is the ...

Structural insights into lacto‐N‐biose I recognition by a family 32 carbohydrate‐binding module from Bifidobacterium bifidum

open access: yesFEBS Letters, EarlyView.
Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.

Multiple solutions for a class of anisotropic p⃗-Laplacian problems

open access: yesBoundary Value Problems, 2023
In this paper we present some existence and multiplicity results for a class of anisotropic p⃗-Laplacian problems with Dirichlet boundary conditions. In particular, the existence of three solutions is pointed out.

Fixed point theorem combined with variational methods for a class of nonlinear impulsive fractional problems with derivative dependence

open access: yesAIMS Mathematics, 2021
In this article, we deal with a class of nonlinear impulsive problems of fractional-order in which nonlinearity is due to the fractional-order derivative term.
