Frobenius extensions of QF-3 rings [PDF]
Proceedings of the American Mathematical Society, 1980 We investigate the inheritance of QF-3 property for ring extensions, mainly, for Frobenius extensions. Let A be a ring with identity. It is proved that a group ring A [ G ] A[G] of A with a finite group G is left QF-3 iff A is left QF-3 and that in case A is a. G-Galois extension of the fixed subring

Relative Arbitrage Opportunities With Interactions Among N Investors
Mathematical Finance, EarlyView.ABSTRACT The relative arbitrage portfolio outperforms a benchmark portfolio over a given time‐horizon with probability one. With market price of risk processes depending on the market portfolio and investors, this paper analyzes the multi‐agent optimization of relative arbitrage opportunities in the coupled system of market and wealth dynamics.

Plant Biotechnology Journal, EarlyView.ABSTRACT Genomic selection (GS) is critical for accelerating genetic gain in modern plant breeding. Deep learning approaches offer powerful non‐linear representation capabilities for modelling non‐additive effects. However, their application in GS remains restricted, as high‐dimensional, low‐sample and noisy data hinder the identification of ...

Quantitative Biology, Volume 14, Issue 3, September 2026.Abstract Single‐cell multi‐omics sequencing technology provides a powerful tool for studying cellular heterogeneity. However, beyond the challenges of sparsity, heterogeneity, and dimensionality differences, a critical challenge in multi‐omics data integration lies in preserving the true regulatory relationships among molecular features.

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 435-447, July 2026.ABSTRACT Purpose Optimal diffusion MRI (dMRI) data for image denoising is often unavailable from scanner reconstruction. In this work, we make available an offline reconstruction pipeline for GE dMRI acquisitions, giving access to complex dMRI data. Furthermore, we compare the efficacy of GE HealthCare's AIR‐Recon DL (ARDL), a proprietary convolutional

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 214-226, July 2026.ABSTRACT Purpose To improve slice profile consistency across echo trains in turbo spin echo (TSE) imaging, thereby reducing image blurring and increasing the accuracy of multi echo spin echo T2$$ {T}_2 $$ mapping. Methods Excitation and refocusing RF pulses were optimized for TSE using a differentiable extended phase graph model that incorporates the ...

Phenome‐ and Genome‐Wide Insights Into Dietary Patterns: Health Consequences and Genetic Basis
eFood, Volume 7, Issue 3, June 2026.Three new dietary patterns were derived from quadratically regularized‐principal components analysis. These patterns showed strong associations with a wide range of diseases and genetic factors. ABSTRACT Dietary patterns (DPs) integrate complex eating behaviors and provide stronger insights into health than analyses of single nutrients.
