High‐Speed Active Imaging Based Target Deviation Measurement and Optical Calibration for Laser Screen Velocimetry Systems

open access: yesAdvanced Photonics Research, Volume 7, Issue 10, October 2026.
A high‐speed active imaging methodology resolves photoelectric response inconsistencies in laser screen velocimetry. By converting unobservable triggering deviations into quantifiable pixel displacements, this approach enables direct in situ spatial calibration of virtual detection screens.

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

open access: yesCytoskeleton, Volume 83, Issue 10, Page 779-794, October 2026.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

A State‐of‐the‐Art Study of Vortex‐Excited Vibration Problems in Large‐Span Flat Steel Box Girder Bridges

open access: yesEngineering Reports, Volume 8, Issue 10, October 2026.
The paper consists of four parts. Specially, the first part analyzes the wind challenges of large‐span bridges, including the formation mechanism of wind‐induced vibration disaster of large‐span bridges and typical cases, as well as the limitations of the current wind design codes. The second part reviews the analysis models and experimental techniques
