Representation Theory of Partially Ordered Vector Spaces [PDF]

open access: yes, 1968
The major results of this work concern perfect ideals of ordered vector spaces, and a representation theory for ordered vector spaces. Perfect ideals are characterized by the property that their annihilators in the order dual are ideals.

Extending monotone seminorms on partially ordered vector spaces

open access: yes, 1998
Given a monotone seminorm on a directed partially ordered vector space, the question arises whether it can be extended to a monotone seminorm on the Dedekind completion.

Filters on a countable vector space

open access: yes, 2021
We study various combinatorial properties, and the implications between them, for filters generated by infinite-dimensional subspaces of a countable vector space.

Shape preserving approximation in vector ordered spaces

open access: yesApplied Mathematics Letters, 2005
AbstractThe aim of this note is to extend some classical results on the shape preserving approximation of real functions (of real variables) to functions with values in ordered vector spaces.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

open access: yesFEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Infinitesimals in ordered vector spaces

open access: yesВладикавказский математический журнал, 2013
An infinitesimal approach to ordered spaces is proposed. Archimedean property and Dedekind completeness in ordered spaces are discussed from a nonstandard point of view.

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

open access: yesFEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

Semi-ordered Vector Space のPositive Cone になるようなSemi-ordered Space について [PDF]

open access: yes, 1973
application/pdfLet R be a semi-ordered vector space. We put R^+={x:x∈R,x≧0}  R^+ is a semi-ordered set with the least element 0 and satisfies the following conditions:    I.(1)for every a,b∈R^+ we have a+b∈R^+,      (2)(a+b)+c=a+(b+c),      (3)a+b=b+a,
