Comparison of Low‐Rank Denoising Methods for Dynamic Deuterium MRSI at 7 T
NMR in Biomedicine, Volume 38, Issue 10, October 2025.Six low‐rank denoising methods for dynamic 2H‐MRSI were compared using simulated and in vivo data: Global PS, Local PS, Stacked PS, SPIN‐SVD, GL‐HOSVD and tMPPCA. SPIN‐SVD performed best in simulations, while SPIN‐SVD, GL‐HOSVD and tMPPCA performed well in vivo. GL‐HOSVD and tMPPCA performed similarly, with tMPPCA preferred for computational efficiency.

Some Conjectures on Wronskian and Casorati Determinants of Orthogonal Polynomials [PDF]
, 2015 In this paper, we conjecture some regularity properties for the zeros of Wronskian and Casorati determinants whose entries are orthogonal polynomials. These determinants are formed by choosing orthogonal polynomials whose degrees run on a finite set of ...

On the extrinsic principal directions of Riemannian submanifolds [PDF]
, 2010 The Casorati curvature of a submanifold $M^n$ of a Riemannianmanifold ${\widetilde{M}^{n + m}}$ is known to be the normalized square of the lengthof the second fundamental form, $C = \frac{1}{n}\|h\|^2$, i.e., inparticular, for hypersurfaces, $C = \frac ...

Molecular 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 ...
