Synthesis and In Vivo Antifungal Evaluation of 3-Acyl-bromoindole Regioisomers: A Multi-Targeting Study on Postharvest Pathogen Control and Molecular Dynamics

Background/Objectives: Postharvest fungal decay caused by Botrytis cinerea and Monilinia fructicola poses major threats to global fruit security. Driven by the need for sustainable crop protection agents, this work presents the systematic synthesis, biological evaluation, and com...

Observation-based analysis of horizontally oriented ice crystals using dual-angle polarization lidar and cloud Doppler radar in Beijing

Abstract. Ice crystal orientation strongly influences cloud radiative properties and remote sensing retrievals, but long-term, high-resolution quantitative observations remain scarce. This study presents comprehensive case studies and statistical analyses of horizontally oriented...

GRB 260310A / SN 2026fgk: A Multi-Wavelength Study of a Nearby Underluminous Long GRB and SN with a Complex Afterglow

Abstract We present a comprehensive multi-wavelength study of GRB 260310A / SN 2026fgk, a nearby (z = 0.153), long-duration gamma-ray burst (GRB) with an exceptionally underluminous prompt γ-ray emission and a Comptonized spectrum. The burst occurred at the edge of a blue host ga...

A framework to compare the performance of spatial disaggregation methods of statistical climate downscaling in South America

Study region Chile and South America. Study focus Climate change is simulated at a coarse scale with General Circulation Models. Impact and regional studies require downscaling to increase spatial resolution. Several downscaling methods exist, but most studies do not analyze or c...

Isolated Cu+–O–Ga3+ Pairs as Structural Motifs that Enhance CO2-to-Methanol Conversion

Abstract Isolated dual-atom sites constitute a promising yet largely unexplored strategy for directing reaction intermediates in CO2 hydrogenation to methanol. In this work, we identify isolated Cu+–O–Ga3+ dual-atom motifs and provide a mechanistically consistent interpretation l...

Inspection-Oriented Predictive Quality Modeling for MDF Manufacturing Using Industrial Process Data and Machine Learning

Continuous medium-density fiberboard (MDF) production presents a persistent quality-assurance problem: destructive laboratory tests return results too late to prevent off-specification material from accumulating before a corrective response is possible. This study develops an ins...

Atmospheric River‐Cyclone Events Disrupting an Antarctic Peninsula Field Campaign: Dynamics, Mesoscale Wind Amplification, and Long‐Term Context

Abstract Extreme weather in the Antarctic Peninsula arises from interactions among large‐scale circulation variability, atmospheric rivers (ARs), extratropical cyclones, and complex coastal terrain, yet the linkages across these scales remain insufficiently resolved. We examine a...

Eleven questions on Hantavirus cardiopulmonary syndrome management in the ICU

Hantavirus cardiopulmonary syndrome (HCPS) due to Andes virus (ANDV) is a fulminant yet potentially reversible cause of respiratory and circulatory failure requiring timely critical care. This article addresses eleven practical questions on ICU management, drawing on clinical exp...

Functional partitioning among core and peripheral bacteria shapes the giant kelp holobiont

The giant kelp Macrocystis pyrifera hosts diverse microbial communities integral to its ecological function, yet the distribution of microbial functions across different holobionts remains poorly resolved. Here, we used genome-resolved metagenomics to examine how microbial occupa...

Data-Driven Ensemble Machine Learning for Multi-Horizon Microalgal Bioprocess Forecasting

Microalgal bioprocesses increasingly rely on predictive modelling to support automated control and reduce the cost of laboratory experimentation. Yet, the scarcity of high-quality datasets and the nonlinear nature of microalgal growth severely limit the accuracy and robustness of...
