Dissipative Ordinary Differential Operators of Even Order [PDF]

open access: yesTransactions of the American Mathematical Society, 1967
The aim of this paper is to study the Cauchy problem for the system (1.1). We shall make the following three assumptions: (1.2) B=B*, C=-C*, D=-D*,..., T=-T*; (1.3) Z-=Bx+A+A* 1 in L2(a, b; F) defined by 1 =a( (Fy, y) dx and a norm IYi= [KY, Y>i]112, L2(a, b; F) becomes a Hilbert space which we shall sometimes denote by H1.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Generalized quadrangles of even order

open access: yesJournal of Algebra, 1974
AbstractThe quadrangles constructed by Tits using ovoids in finite desarguian planes are shown to be special cases of an abstractly much larger class which also includes a recent generalization of Thas. The general construction is obtained by coordinatizing a quadrangle in terms of a certain group of collineations.

Permutation-twisted modules for even order cycles acting on tensor product vertex operator superalgebras [PDF]

open access: yes, 2014
We construct and classify $(1 \; 2 \; \cdots \; k)$-twisted $V^{\otimes k}$-modules for $k$ even and $V$ a vertex operator superalgebra. In particular, we show that the category of weak $(1 \; 2 \; \cdots \; k)$-twisted $V^{\otimes k}$-modules for $k ...

Magnetic black holes with higher-order curvature and gauge corrections in even dimensions

open access: yes, 2010
We obtain magnetic black-hole solutions in arbitrary $n(\ge 4)$ even dimensions for an action given by the Einstein-Gauss-Bonnet-Maxwell-$\Lambda$ pieces with the $F^4$ gauge-correction terms.

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Lower and Upper Solutions for Even Order Boundary Value Problems

open access: yesMathematics, 2019
In this paper, we prove the existence of solutions of nonlinear boundary value problems of arbitrary even order using the lower and upper solutions method.

A question of Frohardt on $2$-groups, and skew translation quadrangles of even order

open access: yes, 2018
We solve a fundamental question posed in Frohardt's 1988 paper [Fro] on finite $2$-groups with Kantor familes, by showing that finite groups with a Kantor family $(\mathcal{F},\mathcal{F}^*)$ having distinct members $A, B \in \mathcal{F}$ such that $A^* \

An intracellular transporter mitigates the CO2‐induced decline in iron content in Arabidopsis shoots

open access: yesFEBS Letters, EarlyView.
This study identifies a gene encoding a transmembrane protein, MIC, which contributes to the reduction of shoot Fe content observed in plants under elevated CO2. MIC is a putative Fe transporter localized to the Golgi and endosomal compartments. Its post‐translational regulation in roots may represent a potential target for improving plant nutrition ...
