Nilpotent subspaces of maximal dimension in semisimple Lie algebras [PDF]

, 2006
We show that a linear subspace of a reductive Lie algebra g that consists of nilpotent elements has dimension at most equal to the number of positive roots, and that any nilpotent subspace attaining this upper bound is equal to the nilradical of a Borel ...

Four Directions, One Solution: Enabling Rapid Diffusion Tensor MRI for Ultra‐Low Field Using Deep Learning

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1413-1426, September 2026.
ABSTRACT Purpose This study revisits the tetrahedral encoding strategy originally proposed to accelerate Diffusion Tensor Magnetic Resonance Imaging (DT‐MRI) by reducing the requisite number of diffusion‐weighted measurements to four. We examine its practical limitations and explore how artificial intelligence (AI) can extend its utility. Specifically,

Repurposing Agricultural Budgets With Multiple Objectives and Fiscal Constraints: A Multicriteria Decision‐Making Policy Tool Applied to Sub‐Saharan African Countries

Journal of Agricultural Economics, Volume 77, Issue 3, Page 910-927, September 2026.
ABSTRACT Repurposing agricultural public resources toward higher‐return incentives and investments can help transform agri‐food systems. This is important for low‐income countries, especially in sub‐Saharan Africa, where limited budgets restrict options for boosting agricultural spending.

Effective When Distinctive: The Role of Phonetic Similarity in Nested Dependency Learning Across Preschool Years

Language Learning, Volume 76, Issue 3, Page 1027-1061, September 2026.
Abstract Parallel tracking of distant relations between speech elements, so‐called nonadjacent dependencies (NADs), is crucial in language development but computationally demanding and acquired only in late preschool years. As processing of single NADs is facilitated when dependent elements are perceptually similar, we investigated how phonetic ...

KPP Dynamics in Predator–Prey Models: A Survey and a Mussel–Algae Case Study

Studies in Applied Mathematics, Volume 157, Issue 3, September 2026.
ABSTRACT We discuss traveling fronts in several coupled reaction–diffusion systems that model predator–prey interactions, as well as other systems that share similar structural features. We review some cases where the traveling fronts exist and are small perturbations of fronts in certain scalar equations of Fisher–KPP or Burgers–FKPP type.

K-Radical classes and product radical classes of MV-algebras

Mathematica Slovaca, 2008
Abstract For an MV-algebra let J 0() be the system of all closed ideals of ; this system is partially ordered by the set-theoretical inclusion. A radical class X of MV-algebras will be called a K-radical class iff, whenever ∈ X and is an MV-algebra with J 0() ≅ J ...

h$h$‐Function, Hilbert–Kunz density function and Frobenius–Poincaré function

Journal of the London Mathematical Society, Volume 114, Issue 3, September 2026.
Abstract Given ideals I,J$I,J$ of a noetherian local ring (R,m)$(R, \mathfrak {m})$ such that I+J$I+J$ is m$\mathfrak {m}$‐primary and a finitely generated R$R$‐module M$M$, we associate an invariant of (M,R,I,J)$(M,R,I,J)$ called the h$h$‐function.

Maximal MV-algebras [PDF]

, 1997
In this paper we define maximal $MV$-algebras, a concept similar to the maximal rings and maximal distributive lattices. We prove that any maximal $MV$-algebra is semilocal, then we characterize a maximal $MV$-algebras as finite direct product of local ...

Transcranial direct current stimulation enhances delayed retention after 5 days of lower‐limb motor skill learning

The Journal of Physiology, Volume 604, Issue 17, Page 7375-7399, 1 September 2026.
Abstract figure legend Schematic overview of the 5 day lower‐limb motor skill learning protocol combining ankle visuomotor practice with transcranial direct current stimulation (tDCS). Participants were allocated to motor skill practice with active tDCS over the leg representation of primary motor cortex (SKILL‐STIM), motor skill practice with sham ...
