In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Mechanical behavior of HTCE propellant: Dependence on strain rate and temperature
Polymer TestingHigh-solid-content polymer composites such as solid propellants are widely used in different fields. Although the proportion of polymer components in the material is relatively low, the mechanical influence of polymers on composite materials is crucial ...

A Degradation Function Consistent with Cocks–Ashby Porosity Kinetics [PDF]
, 2018 The load carrying capacity of ductile materials degrades as a function of porosity, stress state and strain-rate. The effect of these variables on porosity kinetics is captured by the Cocks–Ashby model; however, the Cocks–Ashby model does not account for

Two-state shear diagrams for complex fluids in shear flow [PDF]
, 1999 The possible "phase diagrams'' for shear-induced phase transitions between two phases are collected. We consider shear-thickening and shear-thinning fluids, under conditions of both common strain rate and common stress in the two phases, and present the ...

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

, 2007 We have studied changes in charge-density-wave strain under application of square-wave currents of variable amplitude and frequency by numerically solving the phase-slip augmented diffusion model introduced by Adelman et al (Phys. Rev. B 53, 1833 (1996)).

On probabilistic aspects in the dynamic degradation of ductile materials [PDF]
, 2009 Dynamic loadings produce high stress waves leading to the spallation of ductile materials such as aluminum, copper, magnesium or tantalum. The main mechanism used herein to explain the change of the number of cavities with the stress rate is nucleation ...

YAP1::TFE3 mediates endothelial‐to‐mesenchymal plasticity in epithelioid hemangioendothelioma
Molecular Oncology, EarlyView.The YAP1::TFE3 fusion protein drives endothelial‐to‐mesenchymal transition (EndMT) plasticity, resulting in the loss of endothelial characteristics and gain of mesenchymal‐like properties, including resistance to anoikis, increased migratory capacity, and loss of contact growth inhibition in endothelial cells.

Effects of boundary condition and cell structure on dynamic axial crushing honeycomb
Mechanical Engineering Journal, 2018 The dynamic axially crushing behavior of metal honeycombs was studied with placing emphasis on the effects of boundary condition and cell structure on its characteristics as an energy absorber. Numerical honeycomb models of some metal foil materials were
