Severe right Ore sets and universal localisation

open access: yes, 2007
We introduce the notion of a severe right Ore set in the main as a tool to study universal localisations of rings but also to provide a short proof of P. M. Cohn's classification of homomorphisms from a ring to a division ring. We prove that the category

The divisome is a self-enhancing machine in Escherichia coli and Caulobacter crescentus

open access: yesNature Communications
During bacterial cytokinesis, polymers of the bacterial tubulin FtsZ coalesce into the Z ring to orchestrate divisome assembly and septal cell wall synthesis.

Mechanical power is maximized during contractile ring-like formation in a biomimetic dividing cell model

open access: yesNature Communications
The spatial and temporal dynamics of forces in cells coordinate essential behaviors like division, polarization, and migration. While intracellular signaling initiates contractile ring assembly during cell division, how mechanical forces coordinate ...

A Compact SIW Power Divider for Dual-Band Applications [PDF]

open access: yesRadioengineering, 2020
In this paper, a novel design of highly compact power divider employing substrate-integrated waveguide (SIW) is proposed for dual-band applications. The double-ring asymmetric complimentary split-ring resonators (CSRRs) are utilized to obtain dual-band ...

Multi-Orbital-Angular-Momentum Multi-Ring Fiber for High-Density Space-Division Multiplexing

open access: yesIEEE Photonics Journal, 2013
A compact low-crosstalk multi-ring fiber transmitting multiple orbital angular momentum (OAM) modes is presented. The multi-OAM-mode multi-ring fiber (MOMRF) consists of 7 rings, each supporting 22 modes with 18 OAM ones (i.e., 154 channels in total ...

Pathogenic Chlamydia Lack a Classical Sacculus but Synthesize a Narrow, Mid-cell Peptidoglycan Ring, Regulated by MreB, for Cell Division.

open access: yesPLoS Pathogens, 2016
The peptidoglycan (PG) cell wall is a peptide cross-linked glycan polymer essential for bacterial division and maintenance of cell shape and hydrostatic pressure.
