By altering surface chemical bonds to prolong relaxation time and shift absorption to lower frequencies, SiC/rare earth–sulfur (RE─S, RE = La, Ce, Pr, Sm, Gd, Er) materials achieve excellent low‐frequency electromagnetic wave absorption under extreme conditions, offering a new direction for designing high‐performance SiC‐based absorbers.

Sequential Monte Carlo algorithms for joint target tracking and classification using kinematic radar information [PDF]
This paper considers the problem of joint maneuvering target tracking and classification. Based on recently proposed Monte Carlo techniques, a multiple model (MM) particle filter and a mixture Kalman filter (MKF) are designed for two-class identification

ABSTRACT Plasmodium vivax‐associated anemia is a multifactorial clinical outcome, in which the destruction of uninfected red blood cells (uRBCs) plays a major role in disease development and severity. Here, we identified autoantibody targets within the extracellular loops of Band 3 (B3), a major erythrocyte transmembrane protein.

Long‐distance pollen transport mediated by migratory hoverflies
Long‐distance animal migrations shape ecosystems by redistributing nutrients, connecting populations, and mediating ecological interactions. However, the ecological contributions of many abundant insect migrants remain poorly quantified. Hoverflies are among the most numerous migratory insects and highly efficient pollinators, suggesting that their ...

The NOAA FM-CW Snow-Level Radar
AbstractA vertically pointing radar for monitoring radar brightband height (BBH) has been developed. This new radar utilizes frequency-modulated continuous wave (FM-CW) techniques to provide high-resolution data at a fraction of the cost of comparable pulsed radars.

ABSTRACT Permafrost in northern peatlands occurs within individual palsas or extensive peat plateaus and controls local carbon storage. These permafrost landforms are complex, and their internal structure remains poorly understood. We used quasi‐3D electrical resistivity tomography (ERT) measurements, supported by UAV‐LiDAR topography, frost probing ...

ABSTRACT Grass mowing is one of the most resource‐consuming activities in green maintenance, whether in private areas such as home gardens or in public spaces like urban parks. In recent years, concerns related to climate change, human health, and sustainability have become increasingly prominent in green maintenance, leading manufacturers and industry

Downscaling of Tropical Cyclone Surface Wind Fields With a Hybrid Attention Transformer
Abstract This study employs a Hybrid Attention Transformer‐based super‐resolution model to reconstruct tropical cyclone (TC) surface wind fields. The model downscales coarse‐resolution ERA5 reanalysis data to high‐resolution HWind analyses (1998–2013), increasing the horizontal resolution by a factor of five.
