Precision or Paradox? AI‐Driven Adiposity Imaging in Women With Overweight and Obesity: A Systematic Review and Meta‐Analysis

Obesity Reviews, Volume 27, Issue 9, September 2026.
ABSTRACT Artificial intelligence (AI) enables automated, high‐throughput adiposity quantification, offering refined risk stratification for women with overweight and obesity. We systematically reviewed and meta‐analyzed studies evaluating AI‐based segmentation of visceral, subcutaneous, and total fat in adult women populations (BMI: 25–29.9 and ≥ 30 kg/

Free semigroups of large critical exponent

Journal of Topology, Volume 19, Issue 3, September 2026.
Abstract For a convergence group equipped with an expanding coarse‐cocycle, we construct finitely generated free subsemigroups, which we call Bishop−−Jonessemigroups$\textit{Bishop--Jones semigroups}$, of critical exponent arbitrarily close to but strictly less than the critical exponent of the ambient group.

Prospective Evaluation of Automated Contouring for CT-Based Brachytherapy for Gynecologic Malignancies

Advances in Radiation Oncology
Purpose: The use of deep learning to auto-contour organs at risk (OARs) in gynecologic radiation treatment is well established. Yet, there is limited data investigating the prospective use of auto-contouring in clinical practice. In this study, we assess

Atmospheric River Climatology for the South Atlantic Basin Using an Image Processing‐Based Methodology

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Atmospheric Rivers (ARs) are narrow regions of extratropical water vapor transport, situated in the lower troposphere. They are responsible for a large proportion of poleward vapor transport from the tropics to the midlatitudes. Although ARs are known to cause devastating floods when encountering topography, they are a crucial source of water ...

Image‐based evaluation of a commercial AI synthetic CT generator for brain and prostate MR‐only radiotherapy

Journal of Applied Clinical Medical Physics, Volume 27, Issue 8, August 2026.
Abstract Background Synthetic CTs (sCT) were developed to provide electron density information for MR‐only treatment planning. Some AI‐based sCT generators have received FDA‐clearance and better capture tissue heterogeneity through voxel‐wise mappings to improve image guidance and dose calculation.

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

A cohomology-based Gromov–Hausdorff metric approach for quantifying molecular similarity

Scientific Reports
We introduce a cohomology-based Gromov–Hausdorff ultrametric method to analyze 1-dimensional and higher-dimensional (co)homology groups, focusing on loops, voids, and higher-dimensional cavity structures in simplicial complexes, to address typical ...

Shaping Performance of XP4 versus ProTaper Next in C‐Shaped Canals: A Micro‐CT Study of 3D‐Printed Mandibular Second Molar Replicas

Clinical and Experimental Dental Research, Volume 12, Issue 4, August 2026.
ABSTRACT Introduction This micro‐computed tomography (micro‐CT) study aimed to evaluate the shaping ability of two nickel–titanium (NiTi) rotary systems—XP4 and ProTaper Next (PTN)—in 3D‐printed replicas of C‐shaped canals. Methods Two extracted mandibular second molars with C‐shaped root canals—one continuous (Melton's Category I) and one ...

Shape Analysis and Recognition Method of Artworks Based on Computational Geometry

Engineering Reports, Volume 8, Issue 8, August 2026.
Traditional methods for shape analysis and recognition of artworks have many shortcomings in terms of precision, efficiency, and complex shape processing. Especially when faced with complex or abstract artworks, it is often difficult to provide accurate classification and recognition results.
