Mechanistic Insight Into the Polymorph‐Dependent Photosalient Effect of a White Light or Two‐Photon Activated Photoreactive Molecular Salt

open access: yesAngewandte Chemie, Volume 138, Issue 30, 20 July 2026.
Photocycloaddition in stilbene‐type salt polymorphs exhibit distinct light‐driven responses: OHT‐TI shows a violent photosalient effect under visible and NIR (two‐photon) irradiation, whereas OHT‐TII reacts statically. Packing and computational analysis reveals that shell‐like structures in OHT‐TI frustrate structural relaxation, accumulating explosive

NLOS Identification and Correction Based on Multidimensional Scaling and Quasi-Accurate Detection

open access: yesIEEE Access, 2019
In wireless sensor networks, most of the previous NLOS identification is based on error estimation model established by raw data. In this paper, we propose a method of NLOS identification named NIMQ based on multidimensional scaling (MDS) and Quasi ...

Chiral perovskites for next‐generation chiral optoelectronics and spintronics

open access: yesFlexMat, EarlyView.
Benefiting from structural inversion symmetry breaking and strong spin‐orbit coupling, chiral perovskites possess intriguing chiral optical and spin properties. We overview their advances and core applications in perovskite solar cells, circularly polarized light detectors and spin circularly polarized‐light‐emitting diodes, offering great potential ...

Solution of the NLO BFKL Equation and γ*γ* Cross-Section at NLO [PDF]

open access: yesInternational Journal of Modern Physics: Conference Series, 2015
The analytic NLO cross section of the γ*γ* scattering process at high-energy is calculated. The result is obtained factorizing the scattering amplitude in rapidity space using the high-energy Operator Product Expansion in terms of composite Wilson line operators.

Low‐Complexity Hybrid Beamforming for LEO Satellites: Beam Update Rate Analysis and Advanced Adaptive Precoding

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Low Earth Orbit (LEO) satellite constellations offer unprecedented opportunities for global broadband connectivity but pose significant beamforming challenges due to rapid platform motion and stringent onboard hardware constraints. Fully digital architectures, while optimal in theory, remain impractical for satellite payloads, motivating ...

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

Pharmacological Modulation of Nrf2 Signaling Regulates Oxidative Stress, Inflammation, and Alveolar Bone Loss in Experimental Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Pharmacological activation of Nrf2 attenuated alveolar bone loss and protected periodontal tissues by reducing inflammation and oxidative stress, preserving collagen organization, and favoring bone homeostasis. Reversal of these effects by Nrf2 inhibition further supports Nrf2 signaling as a promising therapeutic target in periodontitis.

Müller Glia–Vasculature Interactions in the Developing Retina

open access: yesGlia, 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
