Global Flash Drought Prediction Through Evaporative Stress Forecasting

open access: yesGeophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Flash droughts pose severe risks to societies and ecosystems due to their sudden onset and rapid intensification. Predicting their vegetation impacts at subseasonal timescales remains difficult. Advances in hybrid physics‐AI models and weather forecasting create new opportunities to enhance the predictability of evaporative stress, a key ...

Design and Simulation of a Carrier PWM‐Based Capacitor to Support a Dynamic Voltage Restorer for Voltage Swell and Voltage Mitigation in the Distribution System

open access: yesEngineering Reports, Volume 8, Issue 7, July 2026.
This study designs and simulates a capacitor‐supported dynamic voltage restorer (DVR) using Carrier PWM control to mitigate voltage sags, swells, and distortions in three‐phase distribution systems. The self‐supported DVR employs a DC‐link capacitor as an energy buffer, eliminating external storage needs. Control via Synchronous Reference Frame Theory (

Vitamin‐Responsive Disorders: From Molecular Basis to Clinical Presentation and Therapy

open access: yesJournal of Inherited Metabolic Disease, Volume 49, Issue 4, July 2026.
ABSTRACT Vitamin‐dependent cofactors are essential for numerous metabolic reactions, and defects affecting their uptake, conversion, utilisation, or regeneration constitute a heterogeneous group of inherited metabolic disorders (IMDs). Although dietary vitamin intake is sufficient to sustain coenzyme synthesis in healthy individuals, it is insufficient

Application of Deep Learning in Virtual Power Plants—A Review

open access: yesEnergy Internet, Volume 3, Issue 2, Page 97-110, July 2026.
ABSTRACT The advancement of deep learning (DL) has substantially improved the power grid’s ability to model and optimise diverse and highly complex tasks. Although intelligent transformation is an inevitable trend, traditional approaches increasingly reveal limitations in computational efficiency, nonlinear nonconvex optimisation, and multi‐layer ...

Toward Reliable Spectroscopic Analysis of Reaction Kinetics in Polaritonic Chemistry

open access: yesNanophotonics, Volume 15, Issue 11, 13 June 2026.
Vibrational strong coupling has been reported to modify chemical reaction rates, yet its mechanism remains unresolved. We expose pitfalls in UV/Vis‐based kinetic analyses and emphasize the need for standardized cavity protocols. ABSTRACT Recent reports suggest that chemical reaction rates can change inside an optical cavity.

Transcriptomic Analysis in the Liver of Two Rabbit Lines Divergently Selected for Intramuscular Fat Content

open access: yesAnimal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT The intramuscular fat (IMF) content is an important indicator of meat quality, affecting the sensory properties of meat. IMF is a complex trait with polygenic nature. This research aimed to identify differentially expressed (DE) genes and key transcription factors (TFs) associated with IMF deposition in the liver of two rabbit lines ...
