Using Airborne Laser Scanning and Sentinel‐2 to Understand Subcanopy Light Regimes and Understory Diversity of Vascular Plants in Temperate Mountain Forests

Remote Sensing in Ecology and Conservation, EarlyView.
This study demonstrates that not just Airborne Laser Scanning, but also Sentinel‐2 can effectively estimate absolute canopy cover and canopy cover heterogeneity ‐ structural metrics that determine the subcanopy light regime, found to be linked to the vascular plant species richness in the understory of temperate mountain forests.

A New BiRNN-SVA Method for Side Lobe Suppression

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The spatially variant apodization (SVA) algorithm, a classic super-resolution method for synthetic aperture radar (SAR) images, can suppress side lobes while maintain the resolution of the main lobe.

A Broadband Information Metasurface-Assisted Target Jamming System for Synthetic Aperture Radar

Remote Sensing
In recent years, jamming strategies for Synthetic Aperture Radar (SAR) pertaining to target detection and identification, such as the creation of false targets, electromagnetic (EM) deception, and signal spoofing, have been increasingly emphasized ...

The Influence of Audio Information Manipulation on the Perceived Atmosphere in Telepresence Systems for Remote Work

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
Remote work, which enables employees to work from home, has emerged as a prominent working style in recent years. However, unlike traditional office environments where the ‘atmosphere of the space’ is naturally shared, remote work relies on screen‐based communication, making it challenging to convey this atmosphere.

Attention‐Based Spatial–Temporal Model for the Entire Indoor Space Temperature Estimation

IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.
This study proposes a novel attention‐based spatial–temporal model for indoor temperature estimation, which integrates positional encoding and an attention mechanism with a fully connected neural network. By jointly capturing temporal dynamics and spatial correlations, the model enables high‐resolution estimation of temperature fields across the entire

Comparing the Effects of Microplastics From Conventional Cigarette Butts and Heated Tobacco Device: The Role of UV‐Induced Aging

Environmental Toxicology, EarlyView.
ABSTRACT Despite the widespread presence of cigarette butts in the environment, the potential toxicological effects posed by microplastics (MPs) derived from them remain poorly understood. In this study, we compared the effects of MPs from conventional cigarette butts (cellulose acetate) and heated tobacco devices (cellulose acetate and polylactic acid

Frequency Channel Selection and Performance Simulation of a Microwave Radiometer for Temperature and Sulfuric Compound Profiling of the Venusian Lower Atmosphere

Earth and Space Science
Exploring the Venusian lower atmosphere is crucial for studying the atmospheric circulation, surface‐atmosphere interactions, and origin and evolution of the Venusian atmosphere and climate. In this study, we investigate the theoretical capabilities of a

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

Wildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.
