Regularized Joint Reconstruction and Slab Combination for Accelerated Three‐Dimensional Multi‐Slab Diffusion‐Weighted Imaging Using Multi‐Scale Energy Models

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2321-2335, November 2026.
ABSTRACT Purpose To jointly reconstruct high‐resolution diffusion‐weighted volumes and eliminate slab‐boundary artifacts while preserving fine anatomical detail from undersampled 3D multi‐slab k‐space acquisitions. Methods A bilinear forward model was formulated to describe the 3D multi‐slab acquisition, treating the image volume and slab excitation ...

Cold‐Air Pooling and Temperature‐Elevation Mapping in a Colorado Watershed

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Near‐surface air temperature grids are important environmental model forcings. In narrow mountain valleys, most gridded products are too coarse to resolve variability across slopes, so regional studies often map temperature across terrain following locally determined lapse rates.

How Predictable Was the Extreme Precipitation Preceding the May 2019 Arkansas River Floods?

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract In May 2019, unprecedented extreme rainfall over the central United States (US) facilitated severe flooding along the Arkansas River. The well‐documented relationship between atmospheric rivers (ARs) and central US heavy precipitation motivated investigation into AR relevance to this event and its predictability on extended timescales.

Why April Stands Out: Monthly Impacts of Internal Variability on Arctic Amplification

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Observed Arctic amplification (AA), defined as the ratio of Arctic‐mean to global‐mean surface air temperature (SAT) trends, peaks in April, a feature not captured by climate models. Here, we quantify the impact of internal variability on Arctic‐mean SAT trends in March, April, and May from 1980 to 2022 using multiple approaches, including ...

Advancing wildlife image analysis: A Graph Attention Contrastive Learning approach for region‐specific mammal classification

Ecological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.
The GACL model combines graph attention and parallel contrastive learning to classify region‐specific mammals from camera‐trap images. Trained on a new large‐scale Korean Wildlife Dataset, it achieves 96.8% accuracy across four classes (wild boar, goral, deer, and other) and outperforms global general‐purpose models at recognizing endemic species.

Evidence‐based management of invasive trees: Using ensemble species distribution models to prioritise control in Rwandan restored montane forests

Ecological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.
This study utilises ensemble species distribution models to quantify the invasion risk of Acacia melanoxylon and Acacia mearnsii within Rwanda's Gishwati‐Mukura Biosphere Reserve. Results indicate that A. melanoxylon poses the greatest threat to Gishwati Forest due to anthropogenic disturbance and soil structure, while invasion in Mukura Forest is ...

Handling Experimental Data in FACPACK: Noise Effects on Duality Relations and Algorithmic Parameter Selection

Journal of Chemometrics, Volume 40, Issue 10, October 2026.
ABSTRACT The area of feasible solutions (AFS) quantifies factor ambiguity in multivariate curve resolution (MCR). Although AFS computation is well‐defined for noise‐free data, experimental datasets require constraint relaxation and parameter tuning, which influence the resulting feasible bands.

A Novel Improved YOLOv8 Approach for Micro‐Motion Trajectory Modeling and Real‐Time Athlete Motion State Estimation

Engineering Reports, Volume 8, Issue 10, October 2026.
There are problems of insufficient accuracy in capturing small motion trajectories and delay in real‐time motion state estimation in the training of track and field athletes. Based on the improved YOLOv8 framework, this paper introduces 3D convolution to construct a spatiotemporal feature pyramid (ST‐FPN) and embeds an optical flow‐guided cross‐frame ...

Analytical Framework for System‐Level Fragility Surfaces of Reinforced Concrete Bridges Under Mainshock‐Aftershock Sequences

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 13, Page 3264-3284, 25 October 2026.
ABSTRACT Conventional single intensity measure (IM) fragility approaches with simplified component dependency assumptions overlook the progressive damage accumulation and evolving inter‐component correlations that govern system behavior under mainshock‐aftershock (MSAS) loading.

Riverbank Erosion Susceptibility Under Varying Sedimentological and Freeze–Thaw Conditions in Cold Climate Regions

Earth Surface Processes and Landforms, Volume 51, Issue 10, October 2026.
Freeze–thaw processes, moisture, and sediment properties control riverbank erosion in boreal–subarctic rivers. Field measurements, geotechnical analyses and monitoring reveal continuous, seasonally driven erosion, while climate projections indicate reduced freezing, potentially increasing erosion risk under warming conditions.
