Influence Mechanisms of Spatial Optimization of the “Terraced Fields‐Gully Land Reclamation Project (GLRP)” Cascades on Erosion‐Transportation Processes in Watershed in the Loess Hilly‐Gully Region of China

Land Degradation &Development, EarlyView.
ABSTRACT Terraced fields and the Gully Land Reclamation Project (GLRP) are important soil and water conservation measures, widely constructed in China's Loess Plateau and other ecologically fragile areas in the world. However, under large‐scale governance scenarios, the impacts of the “terraced fields‐GLRP” cascade system on water and sediment ...

Closing the Gate Before the Horse is out of the Barn: A Model to Effectively Predict the First Fall in Patients with Parkinson's Disease

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Most fall‐prediction models in Parkinson's disease (PD) rely on prior falls, limiting prevention. The Waiting Room of the Future (WROTF) platform collects standardized motor and cognitive measures during routine visits, integrated into electronic health records (EHR).

Deep Learning‐Based Dynamic Segmentation of the Left Atrium in 4D Flow MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To design a deep learning pipeline for automated, time‐resolved segmentation of the left atrium (LA) from 4D flow MRI data. Methods We studied 100 individuals including 65 patients with atrial fibrillation (AF) and 35 healthy subjects (HS) resulting in 2530 4D flow MRI time‐volumes acquired in different centers and scanners.

Fast Localized Calibration for Spatial‐Spectral Excitation Without Fly‐Back Gradients

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Standard spatial‐spectral excitation pulses apply a fly‐back gradient between sub‐pulses, limiting, for example, how thin the slices can be (> 4 mm). Without fly‐back gradients, slices can be as thin as 1.7 mm but require a phase calibration for the sub‐pulses with inverted gradients due to system imperfections.

Composite Fibers of Hydroxypropyl Cellulose and Alginate Spun From Aqueous Solution: Crosslinking Effects on Water Absorption and Mechanical Properties

Polymer Engineering &Science, EarlyView.
Alginate‐HPC composite fibers spun via CaCl2‐induced gelation process. Fiber diameter ranges from 100 to 200 μm after air drying. Higher alginate boosts water absorption in dried fibers. HPC selectively diffuses out when fibers are soaked in water. Crosslinking with hexamethylene diisocyanate improves mechanical strength.

Radar versus optical: The impact of cloud cover when mapping seasonal surface water for health applications in monsoon-affected India.

PLoS ONE
Surface water plays a vital role in the spread of infectious diseases. Information on the spatial and temporal dynamics of surface water availability is thus critical to understanding, monitoring and forecasting disease outbreaks.

Periglacial Puzzles: Unravelling Environmental Controls on Alpine Solifluction Lobe Dimensions and Shape

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Freeze–thaw processes cause periglacial creep (otherwise known as solifluction) which forms solifluction lobes. These are lobate features characterized by a steep riser (front) and a smooth tread (body). Despite the widespread occurrence of these lobes, the controls on their morphometry remain poorly understood. Research into solifluction lobe
