Chiral perovskites for next‐generation chiral optoelectronics and spintronics

FlexMat, 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 ...

Complete NLO corrections to W+W+ scattering and its irreducible background at the LHC

Journal of High Energy Physics, 2017
The process pp → μ +ν μ e+νejj receives several contributions of different orders in the strong and electroweak coupling constants. Using appropriate event selections, this process is dominated by vector-boson scattering (VBS) and has recently been ...

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

International 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

International 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 ...

NLO QCD+EW predictions for 2ℓ2ν diboson signatures at the LHC

Journal of High Energy Physics, 2017
We present next-to-leading order (NLO) calculations including QCD and electroweak (EW) corrections for 2ℓ2ν diboson signatures with two opposite-charge leptons and two neutrinos. Specifically, we study the processes pp→e+μ−νeν¯μ $$ pp\to {e}^{+}{\mu}^{-}{

Broadband and Enhanced Second‐Harmonic Generation in Metallic 3R‐TaS2

Small, EarlyView.
A pronounced and robust SHG response has been observed in metallic 3R‐TaS2. It shows broadband SH conversion from 1020 nm to 1410 nm. Moreover, compared to the sapphire substrate, 3R‐TaS2 flakes with various thicknesses on the gold substrate showed different SHG enhancement; the enhancement factors range from 2.7 to 45.5.

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

Journal 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.

Next-to-leading-order electroweak corrections to the production of three charged leptons plus missing energy at the LHC

Journal of High Energy Physics, 2017
The production of a neutral and a charged vector boson with subsequent decays into three charged leptons and a neutrino is a very important process for precision tests of the Standard Model of elementary particles and in searches for anomalous triple ...

Association between obstructive sleep apnea (OSA) and COVID‐19 severity

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary Obstructive sleep apnea and sleep‐related hypoxia have been associated with higher rates of hospitalization and mortality among patients with Coronavirus disease 2019 (COVID‐19). We further explored the association between obstructive sleep apnea, COVID‐19 severity and related mortality.

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
