Tumor Cell Migration May Be an Inherent “Foraging” Behavior
Medicine Advances, EarlyView.Tumor cells gradually form pseudopodia, migrate to necrotic cells, make contact with them, and absorb necrotic cell debris. During this migration, small vesicles formed by dying tumor cells also gradually migrate toward living tumor cells. Once the nutrients from the necrotic cells have been completely absorbed, the living tumor cells will leave ...

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT This study presents large deformation computational methods to simulate lateral vehicular impacts on steel piles in granular soil. Soil‐mounted longitudinal barrier systems rely on energy dissipation in both the piles and the surrounding soil to safely redirect errant vehicles, so dynamic pile‐soil interaction is important for design ...

Nutrition in Clinical Practice, EarlyView.Abstract Background The coronavirus disease 2019 (COVID‐19) pandemic caused significant morbidity and mortality. Further study of modifiable factors influencing COVID‐19 severity and outcomes continues to be necessary. Serum zinc levels may play a role in modulating COVID‐19 virus replication and consequently influence clinical outcomes.

International Journal of Osteoarchaeology, EarlyView.ABSTRACT Lions (Panthera leo) are apex predators with a well‐documented influence on ecological dynamics, yet their potential role as bone‐accumulating agents remains poorly understood and often debated. Previous taphonomic studies have largely attributed bone accumulations in African savannah ecosystems to other carnivores, such as spotted hyenas ...
