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

Engineering 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

Müller Glia–Vasculature Interactions in the Developing Retina

Glia, Volume 74, Issue 10, October 2026.
Retinal vascular layers form normally despite loss of cholinergic retinal waves. Müller glial processes contact endothelial tip cells early and form Aquaporin‐4‐enriched endfeet. Glial endfoot calcium signals are compartmentalized and occur largely independently of neural activity. ABSTRACT Coordinated signaling among neurons, glia, and the vasculature

Two‐Photon Fluorescence and Second‐Harmonic Generation Microscopy: Principles and Biomedical Applications

Journal of Biophotonics, Volume 19, Issue 10, October 2026.
Compared with single‐photon methods, TPM enables deep‐tissue imaging using near‐infrared light, with excitation confined to the focal plane, thereby reducing photodamage. SHG microscopy images noncentrosymmetric biological structures such as collagen and myosin without fluorescent labels, offering direct structural contrast.

Application of an Amphiphilic Additive Yields Long‐Term Morphological Stability in Organic Solar Cells

Solar RRL, Volume 10, Issue 17, 15 September 2026.
In this study, an amphiphilic molecule p‐toluene sulfonic acid (TSA), was added to the P3HT:PCBM organic solar cell to stabilize the photoactive layer morphology. The addition of TSA enhances both device performance and long‐term device stability. By addressing durability and scalability constraints, the additive improves the overall viability of ...

Scalable Emitter Photonic Integrated Circuits on an Open‐Access Indium Phosphide Foundry

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
An open‐access indium phosphide platform with high‐speed 80 GBaud modulators delivers versatile emitter PICs. By showcasing a widely tunable optical frequency comb generator, a 672 MHz record low‐repetition‐rate mode‐locked extended cavity mode locked laser, and monolithic InP tunable laser with a narrow linewidth of 8.2 kHz, this work presents a ...
