Large‐Scale Drought Forecasting in the U.S. Southern Plains Through a Hybrid Cluster‐Based Wavelet‐Machine Learning Approach

Water Resources Research, Volume 61, Issue 11, November 2025.
Abstract High‐resolution gridded data sets provide valuable opportunities to enhance drought forecasting, but applying complex machine learning algorithms across large spatial domains is computationally challenging. This study presents a novel hybrid approach for forecasting the gridded Standardized Precipitation‐Evapotranspiration Index (SPEI) across ...

Spinal ataxia and computed tomography findings in a Poitou donkey affected with congenital occipitoatlantoaxial malformation

Equine Veterinary Education, Volume 37, Issue 11, Page e261-e265, November 2025.
Summary A 3‐year‐old Poitou donkey was referred for a computed tomography (CT) examination of the cervical spine due to acute deterioration of spinal ataxia. Neurological assessment revealed restricted neck mobility, hypermetria and circumduction of all limbs, indicating a grade 2 out of 5 ataxia.

Glycolytic Enzyme HK2 Phosphorylates nSMase1 to Promote Astrocytic Exosomes Biogenesis Contributing to Acute Ischemic Stroke Injury

Advanced Science, Volume 12, Issue 39, October 20, 2025.
This study reveals that the glycolytic enzyme HK2 mediates hypoxia‐induced astrocytic exosome biogenesis by directly phosphorylating nSMase1. These astrocytic exosomes impair brain endothelial tight junctions. Astrocyte‐specific knockdown of HK2 reduces exosome release and alleviates brain injury after MCAO.

Vibration of a Flexible Hanging Chain with a Mass on the End in a Nonstationary Regime of the Motion Mechanism in Hoisting Machines [PDF]

Journal of Applied and Computational Mechanics
The article is focused on the vibrations of a heavy chain with a mass on the end when the hoisting machines are in a nonstationary regime of motion, assuming that motor or brake torque is a linear function of the speed of the motion mechanism.

Integrated Turbulence and Machine Learning Models Explain Pier Scour in Erodible Channels

Water Resources Research, Volume 61, Issue 9, September 2025.
Abstract Pier scour, a primary cause of bridge failures, stems from turbulent erosion at the pier's approach surface, jeopardizing bridge stability and influencing both river morphology and interactions between aquatic and terrestrial ecosystems. The scouring process, initiated by turbulent eddies interacting with sediments over erodible channels ...
