Nonuniform dichotomy spectrum and reducibility for nonautonomous difference equations
Advances in Nonlinear Analysis, 2021 For nonautonomous linear difference equations, we introduce the notion of the so-called nonuniform dichotomy spectrum and prove a spectral theorem. As an application of the spectral theorem, we prove a reducibility result.

Microporosity of BIF hosted massive hematite ore, Iron Quadrangle, Brazil
Anais da Academia Brasileira de Ciências, 2002 Massive hematite ore (MHO) is a special high-grade iron ore, used as lump ore in the process of obtaining direct reduction iron (DRI). The influence of porosity on the reducibility of MHO from the Capitão do Mato Mine (Iron Quadrangle, Brazil) was ...

Reducibility of beam equations in higher-dimensional spaces
Boundary Value Problems, 2017 In this paper, we reduce a linear d-dimensional beam equation with an x-periodic and t-quasi-periodic potential for most values of the frequency vector via the KAM theorem.

Iron Release from Soybean Seed Ferritin Induced by Cinnamic Acid Derivatives
Pharmaceuticals, 2018 Plant ferritin represents a novel class of iron supplement, which widely co-exists with phenolic acids in a plant diet. However, there are few reports on the effect of these phenolic acids on function of ferritin.

Applied Mathematics Letters, 2002 A convex body (i.e., a compact convex set with interior points in \(\mathbb R^n\), \(n\geq 2\)) which does not properly contain a convex body with the same minimal width is said to be reduced. It is known that every regular \(m\)-gon in \(\mathbb R^2\) with odd vertex number \(m\) is reduced. Being motivated by the problem `Do there exist reduced \(n\)-

European Journal of Combinatorics, 1988 Lovász and the reviewer proved that a connected graphic matroid M is the sum of two matroids of rank at least one if and only if M-e is disconnected for at least one element e. Cunningham generalized this for binary maroids. The present author gives a shorter proof for the general result, using geometric ideas of Mason and a theorem of Lucas on rank ...
