Expansion of normal subsets of odd‐order elements in finite groups

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 4, April 2026.
Abstract Let G$G$ be a finite group and K$K$ a normal subset consisting of odd‐order elements. The rational closure of K$K$, denoted DK$\mathbf {D}_K$, is the set of elements x∈G$x \in G$ with the property that ⟨x⟩=⟨y⟩$\langle x \rangle = \langle y \rangle$ for some y$y$ in K$K$.

Electric Method for the Desulfation of Polysaccharides From Red Microalgae (Porphyridium cruentum) Cultures

open access: yesBiopolymers, Volume 117, Issue 2, March 2026.
A non‐destructive method for depleting sulfates from the red microalgae Porphyridium cruentum by directly exposing the growth medium to a moderate electric field has been developed. The reported electric‐field separation method is a simple, straightforward, and non‐toxic means for the direct recovery of desulfated polysaccharides from P.

An improved 1D area law for frustration-free systems

open access: yes, 2012
We present a new proof for the 1D area law for frustration-free systems with a constant gap, which exponentially improves the entropy bound in Hastings' 1D area law, and which is tight to within a polynomial factor.

Anisotropy, inhomogeneity and inertial range scalings in turbulent convection

open access: yes, 2006
This paper provides a detailed study of scale-by-scale budgets in turbulent Rayleigh-B\'enard convection and aims at testing the applicability of Kolmogorov (1941) and Bolgiano (1959) theories for this flow. Particular emphasis is laid on anisotropic and
