PUSIF-DUNet: Deep SAR Imaging Network With Joint Optimization on Learnable Probabilistic Undersampling and Unambiguous Reconstruction

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Since the minimum antenna area constraint in the spaceborne single-channel synthetic aperture radar (SAR), it's difficult to achieve high-resolution and wide-swath imaging simultaneously.

MODIS-based Daily Lake Ice Extent and Coverage dataset for Tibetan Plateau

Big Earth Data, 2019
The Tibetan Plateau houses numerous lakes, the phenology and duration of lake ice in this region are sensitive to regional and global climate change, and as such are used as key indicators in climate change research, particularly in environment change ...

Small heat shock proteins HspB1 and HspB5 differentially alter the condensation and aggregation of the TDP‐43 low‐complexity domain

Protein Science, Volume 35, Issue 4, April 2026.
Abstract TAR DNA‐binding protein 43 (TDP‐43) is a nucleic acid‐binding protein that regulates processes of mRNA metabolism, during which it undergoes condensation mediated by its C‐terminal low‐complexity domain (TDP‐43LCD). TDP‐43 aggregation and condensation are associated with neurodegenerative disease.

Machine Learning Based Prediction of Tropical Cyclone Rapid Intensification in the Western North Pacific: Importance of Data Augmentation and Loss Function

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract In this study, we developed a TabNet‐based machine learning model to predict tropical cyclone (TC) rapid intensification (RI) in the Western North Pacific. The most significant challenge in predicting RI is the severe class imbalance between rapid and non‐rapid intensification cases, typically 4.2:1 ratio based on 1977–2021 records.

Evaluation of tissue response of experimental calcium silicate‐based endodontic sealers: An in vivo study

European Journal of Oral Sciences, Volume 134, Issue 2, April 2026.
Abstract The aim of this study was to evaluate whether the experimental sealers, composed of tricalcium silicate (CaSi) and CaSi supplemented with calcium hypochlorite (CaSi‐H), stimulate tissue repair. The tissue response of experimental materials was compared with commercially available materials Bio‐C sealer (BC sealer) and BioRoot (BROOT ...

From Spinning Sea Ice Floes to Ocean Enstrophy Spectra in the Marginal Ice Zone

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Quantifying kinetic energy (KE) and enstrophy transfer, mixing, and dissipation in the Arctic Ocean is key to understanding polar ocean dynamics, which are critical components of the global climate system. However, in ice‐covered regions, limited eddy‐resolving observations make characterizing KE and enstrophy transfer across scales ...

Convective Organization in African Easterly Waves Observed During the NAMMA and CPEX‐CV Field Campaigns

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Fundamental questions remain about where and when convection will occur within African easterly waves. In this study, we aim to better understand the dynamical processes that govern moist convective organization at the meso‐alpha scale in tropical easterly waves using NASA airborne field campaigns and satellite observations.

Sustainable Ammonia Electrosynthesis Coupled With Glycerol Valorization via an Adaptive Tri‐Component Catalyst

Angewandte Chemie International Edition, Volume 65, Issue 11, 9 March 2026.
A Cu‐Ni‐W tri‐component catalyst enables efficient nitrate‐to‐ammonia conversion under pulsed electrolysis. Combined experimental and theoretical studies attribute its performance to component synergism and regulated intermediates. Its facile adaptation for glycerol valorization to formic acid underscores a versatile system design concept, advancing ...

Bimetallic (NiFe) and Trimetallic (NiFeCr) Nanoalloys from Metal Oxides Using a Microwave Hydrogen Plasma

Advanced Engineering Materials, Volume 28, Issue 5, 4 March 2026.
Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.
