Using Drones for Large Mammal Monitoring

Mammal Review, Volume 56, Issue 3, September 2026.
Drones were used to obtain video data on animals and locations and distance from the midline was automatically determined by our pipeline so that the input for Distance sampling is generated. ABSTRACT Introduction The emergence of drones has profoundly transformed the field of large mammal monitoring, offering unprecedented capabilities for data ...

Long‐Term Trends in the Ionospheric Equivalent Slab Thickness as a Proxy of Climate Change in the Ionosphere

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Global warming warms the lower atmosphere, but cools and contracts the upper atmosphere. These changes also affect the ionosphere, altering the vertical distribution of plasma through changes in the plasma scale height. Here, we use ionospheric equivalent slab thickness (τ) multidecadal time series, derived through observations from co‐located

A Triple‐Nanoparticle System for Controlled Graphene Nanosheet Stacking: Enabling K/Na‐Ion Battery Anodes with Ultra‐Fast Charging Exceeding Petroleum Vehicle Refueling

Advanced Science, Volume 13, Issue 44, 7 August 2026.
ABSTRACT Large‐ion (K, Na) battery systems mitigate uneven global lithium distribution, while their ability to attain recharge time shorter than refueling would remove the final barrier for secondary batteries to replace petroleum vehicles. However, their large‐ion chemistry makes ultra‐fast charging an even significant challenge.

Tracing river dynamics: Multi‐temporal planform evolution and morphological change analyses in a meandering reach using high‐resolution satellite imagery and UAV data

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
High‐resolution satellite imagery and UAV data enabled detailed morphometric parameter calculation, meander classification and multi‐epoch change detection for the Atrak River's meandering channel. Our results reveal rapid, episodic migration and a nearly tenfold surge in bank erosion triggered by the 2019 extreme flood, with persistent instability at ...

Validation of ShakeMaps Created From Global Navigation Satellite System (GNSS) Velocities

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Ground velocity observations generated through a time difference of Global Navigation Satellite Systems (GNSS) phase observables and orbits have been shown to be comparable to seismic recordings without clipping during intense ground motions. Computing GNSS velocities is also computationally scalable and increases the density of ground motion ...

3D effects of seawater on electrical resistivity tomography near shorelines—Challenges and possible solutions inferred from synthetic and field data

Near Surface Geophysics, Volume 24, Issue 4, Page 364-391, August 2026.
Abstract Electrical resistivity tomography (ERT) is one of the most widely used geophysical techniques for hydrogeological questions, such as investigating the groundwater transition zone between land and sea. The interpretation of 2D coast‐parallel ERT profiles is challenging because most of the electrical current flows through the highly conductive ...

Control System for the Navigation of the Agricultural Robots: A Review

Journal of Field Robotics, Volume 43, Issue 5, Page 3474-3505, August 2026.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...
