FEBS Letters, EarlyView.Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Anisotropic constitutive modeling for nickel base single crystal superalloy Rene N4 at 982 C [PDF]
A back stress/drag stress constitutive model based on a crystallographic approach to model single crystal anisotropy is presented. Experimental results demonstrated the need for the back stress variable in the inelastic flow equations.

Scaling of the Strain Hardening Modulus of Glassy Polymers with the Flow Stress
, 2009 In a recent letter, Govaert et al. examined the relationship between strain hardening modulus $G_r$ and flow stress $\sigma_{flow}$ for five different glassy polymers.

Analysis of temperature effects near mode I cracks in glassy polymers [PDF]
, 2005 A previous isothermal study has shown that the toughness of glassy polymers is governed by the competition between shear yielding and crazing. The present work aims at investigating loading rates for which thermal effects need to be accounted for.

AAA+ protein unfoldases—the Moirai of the proteome
FEBS Letters, EarlyView.AAA+ unfoldases are essential molecular motors that power protein degradation and disaggregation. This review integrates recent cryo‐electron microscopy (cryo‐EM) structures and single‐molecule biophysical data to reconcile competing models of substrate translocation.

Bauschinger effect and back stress in a dual phase steel.
ISIJ International, 1989 To clarify the Bauschinger effect behavior in a dual phase steel and the influence of strain again on it, tension-compression tests were carried out using a Mn-V low alloy steel. This steel shows extremely large transient softening and considerable amount of permanent softening.

Back stress in dislocation creep. Part 1: Basic concepts and measuring techniques [PDF]
A theory is proposed whereby the plastic deformation of metal materials is determined by the difference between the applied stress and the back stress which characterizes the resistance of the material to plastic deformation.

Consistent plane stress-3D conversion of hardening models and yield criteria [PDF]
, 2007 Material models in FE-simulations are used both in 3D and plane stress situations. In this\ud paper it is shown that for models that include kinematic hardening, the conversion from a 3D to a plane\ud stress algorithm needs more adaptations than only ...
