Numerical Comparison of Contact Force Models in the Discrete Element Method
Aerospace, 2022 The discrete element method (DEM) is usually applied in analyzing the scientifical origin/evolution of the asteroids and the landing/sampling of the regolith. In order to manage the contact between the non-spherical granules, the Polygonal Contact Model (

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

A microscopical model for electric‐mechanical contact [PDF]
PAMM, 2003 AbstractIn this paper a model to deal with electric‐mechanical contact problems in the framework of the FEM is presented. On the basis of some micro‐mechanical studies, a new approach is developed to define the non‐linear constitutive law that governs the normal force‐displacement behaviour and the electric resistance of the contacting surfaces.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Experimental Methods for Model Parameters in the Discrete Element Method
KONA Powder and Particle JournalThe Discrete Element Method (DEM) is a widely used numerical method for studying, analyzing, and optimizing particulate processes. Based on contact models, DEM can predict the interactions of particles and particles with wall surfaces.
