Application of High‐Order Direct Flux Reconstruction and Stiffness‐Resilient Time Integration to Simulations of Idealized Atmospheric Flows

International Journal for Numerical Methods in Fluids, EarlyView.
The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

EVSS‐Based Simulation Techniques for the Viscoelastic Fluids With Pure Polymer Melts Using Three‐Field Approach

International Journal for Numerical Methods in Fluids, EarlyView.
This paper presents a finite element method for simulating highly viscoelastic flows of pure polymer melts using the Elastic Viscous Stress Splitting formulation. The method avoids higher‐order derivatives in the weak formulation by reformulating the convective term in the constitutive equation.

Coupled Clustering in Hierarchical Matrices for the Oseen Problem

International Journal for Numerical Methods in Fluids, EarlyView.
Fluid flow problems can be modelled by the Navier‐Stokes or, after linearization, by the Oseen equations. Their discretization results in linear systems in saddle point form which are typically very large and need to be solved iteratively. We propose a novel block structure for hierarchical matrices which is then used to build preconditioners for the ...

Protective Effects of Potential Probiotic Pediococcus acidilactici 100 Against Multi‐Drug‐Resistant Diarrheal Escherichia coli Strains Induced Changes in Caenorhabditis elegans Model System

Food Safety and Health, EarlyView.
This study shows the protective effects of potential probiotic strain of Pediococci strains against diarrheal Escherichia coli strains in Caenorhabditis elegans model system. The E. coli strains resulted in severe morphological and physiological damage to the worm whereas the probiotic interventions were able to reduce these damages.

Guideline for the In Vivo Immunomodulatory Activity Test of Polysaccharide Based on Cyclophosphamide‐Induced Mouse Model

Food Safety and Health, EarlyView.
Abstract graph of the in vivo immunomodulatory activity of polysaccharide based on a cyclophosphamide‐induced mouse model. ABSTRACT The immune system serves as the primary defense mechanism against pathogens and plays a vital role in maintaining host homeostasis. In recent years, natural polysaccharides have emerged as promising immunomodulators due to

Necessary HRM Practices for Extended Working Lives in Tight and Loose Societies: A Comparative Perspective

Human Resource Management, EarlyView.
ABSTRACT The aging workforce demands evidence‐based human resource practices that lengthen working lives. Building on the Conservation of Resources theory (Hobfoll 1989), we investigate which organizational practices are indispensable for expanding older workers' occupational future time perspective (OFTP)—people's perceived opportunities and remaining
