AIMC-Spec: A Benchmark Dataset for Automatic Intrapulse Modulation Classification Under Variable Noise Conditions

IEEE Access
A lack of standardized datasets has long hindered progress in automatic intrapulse modulation classification (AIMC)—a critical task in radar signal analysis for electronic support systems, particularly under noisy or degraded conditions.

Effects of Glucagon‐Like Peptide‐1 Receptor Agonists (Mono and Combination Therapy) on Energy Expenditure: A Scoping Review

Obesity Reviews, Volume 27, Issue 8, August 2026.
ABSTRACT Introduction Weight loss results in reduced energy expenditure (EE) due to body composition alterations (e.g., fat‐free mass and fat mass losses) and mass‐independent adaptations in EE (e.g., hormones). Glucagon‐like peptide‐1 receptor agonists (GLP‐1RA) are indicated for obesity management; however, their effects on EE remain unclear ...

To Align or Not to Align? That Is the Question

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Previous studies have shown that vertically misaligned circulations are commonly found in weaker tropical cyclones (TCs) below hurricane strength, whereas TCs of hurricane intensity more typically exhibit vertically aligned vortices. Thus an important step in the TC intensification process is achieving a vertically aligned circulation.

On the Tropical Nature of an Intense Mediterranean Cyclone in the Ocean‐Atmosphere System

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The Mediterranean basin hosts a large number of cyclones every year. Among them, some rare cases named medicanes present similarities with tropical cyclones but their dynamical characteristics are debated. The ocean‐atmosphere dynamics of Medicane Ianos (2020) are studied here through km‐scale fully coupled ocean‐wave‐atmosphere simulations ...

Contribution of Aloft Gravitational Sorting and Lower‐Part Coalescence to Precipitation Over the Southeastern Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Observational constraints on the vertical microphysical evolution of mixed‐phase precipitation across the melting layer over the high‐altitude of southeastern Tibetan Plateau remain scarce. Using collocated two‐dimensional video disdrometer and Micro Rain Radar measurements in rainy seasons of 2022–2025, we characterize the vertical ...

Space‐Time‐Coding Metasurfaces Enabling Programmable Range‐Angle‐Dependent Energy Auto‐Scanning

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
This paper presents a novel energy auto‐scanning system based on a space‐time‐coding metasurface. By applying progressive time‐delayed, time‐varying phase modulation, the system generates non‐uniform, temporally evolving electromagnetic field distributions across both angle and range.

Fully Polarimetric Radar Cross‐Section and High‐Resolution Range Profile Co‐Modulation via Diversely Time‐Modulated Metasurface

Nanophotonics, Volume 15, Issue 14, 27 July 2026.
A diversely time‐modulated metasurface enables broadband co‐modulation of fully polarimetric radar cross section and high‐resolution range profiles. By integrating anti‐parallel PIN diodes and programmable temporal coding, the platform dynamically redistributes scattering among HH/VV and HV/VH channels, generating tunable target weakening, false ...

On radar polarimetry in FM-CW radar

On radar polarimetry in FM-CW radar
This paper attempts to apply the principle of radar polarimetry to wideband synthetic aperture FM-CW radar and presents a basic polarimetric detection result of a linear target in a laboratory measurement. Although the principle of radar polarimetry has well been established for the completely polarized wave and for the monostatic case, it still needs ...

An Ultra-Wide Swath Synthetic Aperture Radar Imaging System via Chaotic Frequency Modulation Signals and a Random Pulse Repetition Interval Variation Strategy

Remote Sensing
Ultra-wide swath synthetic aperture radar (SAR) systems are of great significance for applications such as terrain measurement and ocean monitoring. In conventional SAR systems, targets echo from the near-range and far-range of an observed swath mutually

Information theoretic waveform design with applications to adaptive‐on‐transmit radar

IET Radar, Sonar & Navigation
The marginal Fisher information (MFI) metric is used to design waveforms for the sake of informationally optimal adaptive‐on‐transmit radar operation. A framework for MFI waveform design is developed and the Polyphase‐Coded FM (PCFM) waveform model is ...
