HFDNN: A Hybrid Fusion Deep Neural Network for Robust Automatic Modulation Classification in Adverse Wireless Environments

open access: yesIEEE Access
Automatic Modulation Classification (AMC) plays a vital role in modern wireless communication systems, particularly in domains such as defense, the Internet of Things (IoT), and cognitive radio, where resilience to interference is essential.

Explicit‐Implicit Material Point Method for Dense Granular Flows With a Novel Regularized µ(I) Model

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 7, Page 3256-3273, May 2026.
ABSTRACT The material point method (MPM) is widely employed to simulate granular flows. Although explicit time integration is favored in most current MPM implementations for its simplicity, it cannot rigorously incorporate the incompressible µ(I)‐rheology, an efficient model ubiquitously adopted in other particle‐based numerical methods. While operator‐

Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 1884-1904, May 2026.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Patterns and Drivers of Cliff Erosion in Big Sur, California, USA Using Repeat Photogrammetry, 2017–2023

open access: yesEarth and Space Science, Volume 13, Issue 5, May 2026.
Abstract Seacliff erosion in steep terrain poses major risks to transportation and critical infrastructure. In Big Sur, California, USA, seacliff erosion threatens the sustainability of the central coast stretch of California State Route 1, a transportation corridor that is critical to the region's economy.

Ecosystem‐Scale Methane Emissions From Peatlands of the Hudson Bay Lowlands

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Northern peatlands are important sources of methane (CH4) in the atmosphere. However, the magnitude of CH4 emissions and their response to environmental factors are poorly constrained within the Hudson Bay Lowlands (HBL), the largest contiguous peatland complex in North America. This study investigated seasonal (April–November) eddy covariance‐

A Decade of Airborne Electromagnetic Surveying Lake Menindee (Australia) Under Varying Water Levels

open access: yesGeophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT Time domain airborne electromagnetic (AEM) surveying is a mature geophysical tool for imaging the Earth's shallow subsurface. It produces images of the electromagnetic conductivity structure of the earth, down to depths of a few hundred metres.

Eukaryovorous Predation in Evolutionarily Significant Excavate‐Like Flagellates

open access: yesJournal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Accumulating evidence suggests that the Last Eukaryotic Common Ancestor (LECA) resembled contemporary excavates, a non‐monophyletic group of deep branching flagellates. Here we explore the functional ecology of distantly related deep‐branching “excavate‐like” flagellates (in Alveolata and Provora) that share with many excavates a vane‐bearing ...

Methane and Ethane Emission Rates, Intensities, and Trends: Aircraft Mass Balance Insights Over the Denver‐Julesburg Basin, Fall 2021

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Despite a 2.1‐fold increase in oil and gas (O&G) production from 2012 to 2021 in the Wattenberg Field (WF) area of the Denver‐Julesburg Basin (DJB), total methane (CH4) emissions have remained unchanged within measurement uncertainties (26.0 ± 6.8 t/hr in 2012, 24.0 ± 5 t/hr in 2015, and 21.4 ± 5.7 t/hr in 2021), while ethane (C2H6) emissions ...
