Passing to the Limit in a Wasserstein Gradient Flow: From Diffusion to Reaction [PDF]

open access: yes, 2011
We study a singular-limit problem arising in the modelling of chemical reactions. At finite {\epsilon} > 0, the system is described by a Fokker-Planck convection-diffusion equation with a double-well convection potential.

Accelerating 3D radial MPnRAGE using a self‐supervised deep factor model

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 3, Page 1191-1201, September 2025.
ABSTRACT Purpose To develop a self‐supervised and memory‐efficient deep learning image reconstruction method for 4D non‐Cartesian MRI with high resolution and a large parametric dimension. Methods The deep factor model (DFM) represents a parametric series of 3D multicontrast images using a neural network conditioned by the inversion time using ...

Geometric modeling of phase ordering for the isotropic–smectic A phase transition

open access: yesFrontiers in Soft Matter
BackgroundLiquid crystal (LC) mesophases have an orientational and positional order that can be found in both synthetic and biological materials. These orders are maintained until some parameter, mainly the temperature or concentration, is changed ...

High‐resolution, volumetric diffusion‐weighted MR spectroscopic imaging of the brain

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 2, Page 450-469, August 2025.
ABSTRACT Purpose To achieve high‐resolution, three‐dimensional (3D) quantitative diffusion‐weighted MR spectroscopic imaging (DW‐MRSI) for molecule‐specific microstructural imaging of the brain. Methods We introduced and integrated several innovative acquisition and processing strategies for DW‐MRSI: (a) a new double‐spin‐echo sequence combining ...

Curvature Bounds and Casorati Pinching for Submanifolds in Kähler Product Manifolds

open access: yesAxioms
In this paper, we establish sharp pinching inequalities that relate the generalized δ-Casorati curvatures to the normalized scalar curvature of submanifolds immersed in Kähler product manifolds endowed with a quarter-symmetric metric connection.

Assessment of the Nutraceutical Properties of Wild Strawberry (Fragaria vesca L.) Extracts on Human Colorectal Cell Lines

open access: yesMolecular Nutrition &Food Research, Volume 69, Issue 11, June 2025.
The study explores the nutraceutical potential of wild strawberry (Fragaria vesca L.) by assessing its effects on multiple colorectal carcinoma cell lines. Wild strawberry phytochemicals were able to reduce SW480 cell viability by inducing cell cycle arrest and by promoting programmed cell death in E705 cells, with no toxicity on healthy colorectal ...

Inequalities for algebraic Casorati curvatures and their applications

open access: yes, 2016
The notion of different kind of algebraic Casorati curvatures are introduced. Some results expressing basic Casorati inequalities for algebraic Casorati curvatures are presented. Equality cases are also discussed. As a simple application, basic Casorati inequalities for different $ $-Casorati curvatures for Riemannian submanifolds are presented ...
