Deep Learning for Satellite‐Based Forest Disturbance Monitoring: Recent Advances and Challenges

open access: yesWIREs Data Mining and Knowledge Discovery, Volume 16, Issue 2, June 2026.
Overview of key research challenges in forest disturbance monitoring, including the detection of disturbances of varying severity, the attribution of disturbance agents, and the development of models capable of generalizing across regions. ABSTRACT Climate change and land use pressures are intensifying forest disturbances in many world regions, as ...

Bio‐Inspired Multimodal Hardware Front‐End Enabled by 2D Floating‐Gate Memory for UAV Perception

open access: yesAdvanced Functional Materials, Volume 36, Issue 37, 7 May 2026.
A MoS2/h‐BN /graphene floating‐gate memory underpins a bio‐inspired multimodal front end that integrates visual, inertial, and airflow cues. A 4 × 4 FG memory array encodes temporal intensity differences, while IMU‐ and airflow‐driven threshold modulation suppresses self‐motion artifacts, enabling fast, low‐power, robust autonomous UAV tracking and ...

MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band

open access: yesAdvanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...

Midwestern farmers' willingness to engage with precision agriculture technologies and on‐farm precision experimentation

open access: yesAgronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Precision agriculture technologies (PATs) have revolutionized the agriculture industry and provide many benefits to farmers. Among these benefits is the ability to conduct experiments in a process known as on‐farm precision experimentation (OFPE). By conducting these experiments and through collaboration with researchers, crop consultants, and

A Performance‐Based Earthquake Fatality Modeling Framework Using Collapse Volume Ratios

open access: yesEarthquake Spectra, Volume 42, Issue 2, May 2026.
Conventional earthquake fatality models are commonly implemented using a binary representation of building collapse, an assumption that overlooks severe failure modes and systematically underestimates fatalities. To address this limitation, this study advances the collapse volume ratio—a continuous metric quantifying the reduction of survivable space ...

Rapid Unmanned Aerial Vehicle launcher (UAV) system

open access: yes, 2018
The disclosure provides a rapid UAV launcher comprising an upper shuttle assembly and typically a plurality of rail systems. Each rail system comprises a lower shuttle assembly extending into a rail channel and translating over a rail surface. The rail channels of each rail system e generally parallel.

Mapping River Bed Topography in Whitewater Rapids Using Bathymetric LiDAR

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 886-900, May 2026.
ABSTRACT Bathymetric LiDAR captures river topography efficiently for clear and shallow water, but for mountain rivers, whitewater rapids still pose challenges. This study proposes a novel method to enable the extraction of bottom returns specifically in turbulent whitewater sections.
