Advanced Science, EarlyView.The protein aggregates and gene expression in the middle temporal gyrus (MTG) and somatosensory cortex (SOM) of the postmortem brains of 13 Alzheimer's disease patients were studied in detail, revealing that small hyperphosphorylated tau aggregates increase with Braak stage driven by microglial inflammation.

Advances in Nonlinear Analysis, 2022 In this article, we establish a viscosity method for random homogenization of an obstacle problem with nondivergence structure. We study the asymptotic behavior of the viscosity solution uε{u}_{\varepsilon } of fully nonlinear equations in a perforated ...

Micropolar Modelling of Periodic Cauchy Materials Based on Asymptotic Homogenization [PDF]
, 2022 A micropolar-based asymptotic homogenization approach for the anal- ysis of composite materials with periodic microstructure is proposed. The macro descriptors are directly linked to both suitable perturbation functions, obtained via asymptotic ...

Inclusive Leadership and CEO Gender: The Role of Tenure and Education in an Emerging Economy
Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Gender inequality in corporate leadership remains a critical challenge, particularly in emerging economies where institutional constraints shape access to top executive positions. This study examines firm performance differences between women and men CEOs in Ecuador, focusing on the moderating roles of tenure and formal education.

Ecography, EarlyView.Habitat fragmentation alters species diversity and reshapes community composition. However, conventional pairwise approaches to compositional variation (i.e. beta diversity metrics) do not explicitly characterize how species sharing or turnover change with the number of habitat patches.

Locally periodic unfolding method and two-scale convergence on surfaces of locally periodic microstructures [PDF]
, 2015 In this paper we generalize the periodic unfolding method and the notion of two-scale convergence on surfaces of periodic microstructures to locally-periodic situations.

Journal of Function Spaces and Applications, 2011 We prove a homogenization result for monotone operators by using the method of multiscale convergence. More precisely, we study the asymptotic behavior as ε→0 of the solutions uε of the nonlinear equation divaε(x,∇uε)=divbε, where both aε and bε ...

Short-time diffusive fluxes over membrane receptors yields the direction of a signalling source
Royal Society Open Science, 2023 An essential ability of many cell types is to detect stimuli in the form of shallow chemical gradients. Such cues may indicate the direction that new growth should occur, or the location of a mate.

FlexMat, EarlyView.The buried interface is a critical determinant of efficiency and stability in inverted flexible perovskite solar cells (IFPSCs). This Perspective summarizes advances in hole transporting materials for IFPSCs, including polymeric, small‐molecule, inorganic, and hybrid systems, and discusses the prospects and feasibility of emerging molecular design and ...
