Enhanced Retrieval of Spring Snow Depth Over Pan‐Arctic Sea Ice From AMSR2 Observations for 2013–2023 Using Multi‐Model Machine Learning

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Snow on sea ice modulates the Earth's radiation budget and sea ice mass balance, yet satellite retrievals of Arctic snow depth remain subject to substantial algorithmic uncertainty. We develop a multi‐model machine learning (ML) framework for retrieving spring snow depth over Arctic sea ice from Advanced Microwave Scanning Radiometer 2 (AMSR2).

Genetic analysis of porcine circovirus type 2 from pigs affected with PMWS in Chile reveals intergenotypic recombination

Virology Journal, 2017
Background Porcine circovirus type 2 (PCV2) is a very small, non-enveloped and icosahedral virus, with circular single stranded DNA genome. This virus is the most ubiquitous and persistent pathogen currently affecting the swine industry worldwide.

Mesonet‐Based Ground Validation of IMERG‐V07 and GSMaP‐V08 Over a Semi‐Arid Dryland Ecosystem in West Texas

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Climate change has caused highly uncertain precipitation regimes and associated hydrometeorological hazards over global drylands. Accurate precipitation measurements are vital for monitoring dryland ecohydrology. Satellite precipitation products (SPPs), including the Integrated Multi‐satellitE Retrievals for GPM (Global Precipitation ...

Quantitative Evaluation and Error Analysis of GPM DPR Rainfall Products (Version 07) Over Yangtze‐and‐Huai River Basin in China

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Dual‐Frequency Precipitation Radar (DPR) aboard the Global Precipitation Measurement (GPM) core satellite has advanced global precipitation monitoring with consistent long‐term data. This study evaluates the rainfall rate from GPM DPR version 07 Level‐2 products over the Yangtze‐and‐Huai River Basin with rain gauge observations.

Temperature‐Modulated Threshold Response in a Volatile Memristor: Toward a Biomimetic Polymodal Nociceptive System

Advanced Functional Materials, Volume 36, Issue 45, 5 June 2026.
This study demonstrates an artificial polymodal nociceptor whose firing threshold is actively modulated by temperature. A volatile TiN/TiOx/ZnO/TiOx/ITO memristor shows interfacial ion–driven resistive switching and membrane‐potential‐like dynamics, enabling temperature‐dependent nociceptive behavior.

Detection and association of porcine bocaviruses 1 and 3 and porcine parvovirus 4 with postweaning multisystemic wasting syndrome (PMWS) in Brazil

Discover Viruses
The increasing identification of novel parvoviruses in swine has raised questions about their role in multifactorial syndromes like PMWS. This study used PCR to investigate the presence of porcine parvovirus 4 (PPV4), porcine bocavirus 1 (PBoV1), and ...
