Modeling and Optimization of Frequency‐Doubled Radio‐Over‐Fiber Link Based on Deep Learning Technique

open access: yesAdvanced Photonics Research, Volume 7, Issue 3, March 2026.
This article proposes a deep learning (DL) approach for modeling and optimizing frequency‐doubled radio‐over‐fiber links. By collectively replacing traditional components with DL model, accurate system evaluation is achieved. Moreover, through an end‐to‐end architecture, performance optimization is accomplished.

Gallium Nitride Semiconductor Resonant Tunneling Transistor

open access: yesAdvanced Science, Volume 13, Issue 13, 3 March 2026.
Three‐terminal GaN semiconductor resonant tunneling transistors (RTTs), which comprise an double‐barrier AlN/GaN/AlN resonant tunneling diode integrated with a GaN high‐electron‐mobility transistor (HEMT) through epitaxial growth in series and parallel configuraions, respectively.

Zolpidem restores sleep and decreases amyloid in a mouse model

open access: yesAlzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract INTRODUCTION Deficits in non–rapid eye movement (NREM) sleep facilitate Alzheimer's disease (AD) progression. Enhancing gamma‐aminobutyric acid‐ergic (GABAergic) signaling can restore sleep. Unbiased computational analysis identified zolpidem as high‐affinity GABA receptor modulator facilitating chloride transport that could slow AD.

Chromones as Nonclassical Inhibitors of Carbonic Anhydrase IX and XII Isoforms: Probing Chromone‐Based Derivatives

open access: yesArchiv der Pharmazie, Volume 359, Issue 3, March 2026.
Chromone‐based derivatives were synthesized and evaluated for selective inhibition of tumor‐associated carbonic anhydrases IX and XII. Structure–activity relationships, docking studies, and ADMET profiling revealed promising candidates with selective tumoral isoform inhibition, supporting their potential as anticancer leads. ABSTRACT A small library of

Semiclassical inequalities for Dirichlet and Neumann Laplacians on convex domains

open access: yesCommunications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 762-822, March 2026.
Abstract We are interested in inequalities that bound the Riesz means of the eigenvalues of the Dirichlet and Neumann Laplacians in terms of their semiclassical counterpart. We show that the classical inequalities of Berezin–Li–Yau and Kröger, valid for Riesz exponents γ≥1$\gamma \ge 1$, extend to certain values γ<1$\gamma <1$, provided the underlying ...

Photo‐Excitations in Halide Perovskites: Where Do Simulations and Experiments Meet?

open access: yesLaser &Photonics Reviews, Volume 20, Issue 6, 18 March 2026.
Aiming to bridge the gap between simulations and measurements of light–matter couplings and photo‐excitations in new functional materials, this perspective highlights insights and bottlenecks of state‐of‐the‐art experimental and theoretical methods (2D electronic spectroscopy vs.
