Finite element simulation of barge impact into a rigid wall
Alexandria Engineering Journal, 2014 The forces and locations of inland barge impacts currently control the design specifications for lock walls. This has resulted in a significant increase in the final construction costs of these walls.

Making tau amyloid models in vitro: a crucial and underestimated challenge
FEBS Letters, EarlyView.This review highlights the challenges of producing in vitro amyloid assemblies of the tau protein. We review how accurately the existing protocols mimic tau deposits found in the brain of patients affected with tauopathies. We discuss the important properties that should be considered when forming amyloids and the benchmarks that should be used to ...

On the Origins of Hamilton’s Principle(s)
EncyclopediaThis entry first provides an overview of the historical, cultural and epistemological background that is key for Hamilton’s positions on mechanics. We consider the investigations on geometrical optics in the 17th and 18th centuries, Euler’s and Lagrange ...

Classical analytical mechanics and entropy production [PDF]
American Journal of Physics, 2007 The usual canonical Hamiltonian or Lagrangian formalism of classical mechanics applied to macroscopic systems describes energy conserving adiabatic motion. If irreversible diabatic processes are to be included, the law of increasing entropy must also be considered. The notion of entropy then enters into the classical mechanical formalism. The resulting

The power of microRNA regulation—insights into immunity and metabolism
FEBS Letters, EarlyView.MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

Results in Physics, 2023 For the system with non-holonomic constraints, the principle of least action does not seem to lead to the equations describing the motion, which are consistent with the physical behaviour. Here, some considerations are developed on this fundamental topic

FEBS Letters, EarlyView.In lymphoid organs, antigen recognition and B cell receptor signaling rely on integrins and the cytoskeleton. Integrins act as mechanoreceptors, couple B cell receptor activation to cytoskeletal remodeling, and support immune synapse formation as well as antigen extraction.

A dinâmica de um elipsoide em rotação
Revista Brasileira de Ensino de FísicaUm fenômeno físico interessante que contraria nosso senso comum concerne à dinâmica do movimento de um elipsoide em rotação numa superfície não lisa. Um elipsoide em rotação é, por exemplo, um ovo cozido, girando numa mesa de superfície áspera.

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...
