Light and heavy particles on a fluctuating surface: Bunchwise balance, irreducible sequences, and local density-height correlations

Physical Review Research, 2020
We study the early-time and coarsening dynamics in the light-heavy model, a system consisting of two species of particles (light and heavy) coupled to a fluctuating surface (described by tilt fields).

Radical classes of l-groups

International Journal of Mathematics and Mathematical Sciences, 1994
The main results of this paper concern radical classes of l-groups. In the sections 2-3 the relationship between several radical classes of l-groups are discussed and the characteristic properties for several radical mappings are given. In the sections 5-

Dedekind sigma-complete l-groups and Riesz spaces as varieties

, 2017
We prove that the category of Dedekind $\sigma$-complete Riesz spaces is an infinitary variety, and we provide an explicit equational axiomatization. In fact, we show that finitely many axioms suffice over the usual equational axiomatization of Riesz ...

Proof Theory and Ordered Groups

, 2017
Ordering theorems, characterizing when partial orders of a group extend to total orders, are used to generate hypersequent calculi for varieties of lattice-ordered groups (l-groups).

Valuations of Lattice-Ordered Groups

Journal of Algebra, 1997
The authors study valuations on lattice-ordered groups with values in a lattice of order ideals of the root system of regular subgroups. They use these valuations to obtain new and old results for archimedean extensions and archimedean closures of lattice-ordered groups. In the penultimate section of their paper, they define \(\Delta\)-extensions and \(

Amalgamation bases for the class of lattice-ordered groups

, 2014
We prove TheoremA. The cardinal product of two copies of the integers is an amalgamation base for the class of all lattice-ordered groups but their lexicographic product is not.This answers Problem 27 of [Black Swamp Problem Book (W. Charles Holland, ed.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

On the lattice of normal subgroups in ultraproducts of compact simple groups

, 2013
We prove that the lattice of normal subgroups of ultraproducts of compact simple non-abelian groups is distributive. In the case of ultraproducts of finite simple groups or compact connected simple Lie groups of bounded rank the set of normal subgroups ...
