A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Equilibrium and stability of beams with elastoplastic semi-rigid joints [PDF]

open access: yesArchives of Civil Engineering
The classical theory of beams admits two types of connections between structural elements: perfectly rigid and perfectly flexible. However, the engineering reality calls for a more general approach to joint modelling.

Closed-form approach for the elastic critical moment of I-girders with corrugated web

open access: yesThin-Walled Structures
Using corrugated web girders offers several advantages, including increased resistance to lateral-torsional buckling. Researchers have proposed various methods for determining the critical moment value as a function of the cross-sectional geometry. Previous studies have suggested that the enhanced critical moment is attributable to a larger warping ...
