Rare Metals, EarlyView.ABSTRACT Regulating negative parameters of metacomposites is mainly limited by their unclear mechanisms, which affects their practical applications in new sensing, communication, electromagnetic (EM) protection and other fields. This work proposes a dual‐functional competitive design strategy based on the waste corncob‐derived carbon/polyaniline ...

International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT The raindrop size distribution (DSD) plays an essential role in understanding rain attenuation effects at extremely high frequencies (EHFs). Over 1 year of DSD measurements was taken at different Köppen–Geiger climate classifications within the United States. Optical disdrometers from Thies Clima were used to measure both the size and velocity

Journal of Clinical Periodontology, EarlyView.ABSTRACT Objective To investigate the associations between peri‐implant phenotype characteristics and long‐term outcomes of soft tissue–level implants. Methods Twenty‐five tissue‐level implants from a previous controlled clinical trial were evaluated at 1‐ and 5‐year follow‐ups after crown delivery.

Doppler Radar Techniques for Accurate Respiration Characterization and Subject Identification
IEEE Journal on Emerging and Selected Topics in Circuits and Systems, 2018 A low distortion dc coupled CW radar system with high signal to noise ratio is capable of accurate representation of respiration in human subjects. We propose to test the hypothesis that a non-contact physiological radar monitoring system which measures ...

Skillful Polar WRF Cloud Modeling of a Warm Winter Atmospheric River at the Antarctic Peninsula
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.Abstract Atmospheric rivers are episodic events that can advect relatively large quantities of moisture to Antarctica, contributing to both disproportionate precipitation and melting events. The Year of Polar Prediction, an international effort to improve weather prediction over the southern polar region, presents an opportunity to study the clouds and

Progress in existing and planned MST radars [PDF]
, 1986 Radar systems are described which use two different wind measuring techniques: the partial-reflection drift technique and the mesosphere-stratosphere-troposphere (MST) or Doppler beam-swing radar technique.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.Abstract Low‐level jets (LLJs), as dynamically significant narrow air currents in the lower troposphere, profoundly influence regional weather and anthropogenic activities. Motivated by persistent LLJs detected through Doppler LiDAR observations during March to April 2021, this study systematically characterizes these LLJs over Juehua Island (western ...

Improved rain rate and drop size retrievals from airborne Doppler radar [PDF]
Atmospheric Chemistry and Physics, 2017 Satellite remote sensing of rain is important for quantifying the hydrological cycle, atmospheric energy budget, and cloud and precipitation processes; however, radar retrievals of rain rate are sensitive to assumptions about the raindrop size ...
