LET-99 functions in the astral furrowing pathway, where it is required for myosin enrichment in the contractile ring. [PDF]

open access: yes, 2017
The anaphase spindle determines the position of the cytokinesis furrow, such that the contractile ring assembles in an equatorial zone between the two spindle poles.

Multiclass scheduling algorithms for the DAVID metro network [PDF]

open access: yes, 2004
—The data and voice integration over dense wavelength-division-multiplexing (DAVID) project proposes a metro network architecture based on several wavelength-division-multiplexing (WDM) rings interconnected via a bufferless optical switch called Hub. The

Cooperative recruitment of FtsW to the division site of Bacillus subtilis

open access: yesFrontiers in Microbiology, 2016
Five essential proteins are known to assemble at the division site of Bacillus subtilis. However, the recruitment of the FtsW homolog is still unclear. Here, by taking advantage of GFP fusions and spore germination, we show that the assembly of FtsW is ...

Bacterial cell-size changes resulting from altering the relative expression of Min proteins

open access: yesNature Communications, 2023
The timing of cell division, and thus cell size in bacteria, is determined in part by the accumulation dynamics of the protein FtsZ, which forms the septal ring. FtsZ localization depends on membrane-associated Min proteins, which inhibit FtsZ binding to

A conserved cell division protein directly regulates FtsZ dynamics in filamentous and unicellular actinobacteria

open access: yeseLife, 2021
Bacterial cell division is driven by the polymerization of the GTPase FtsZ into a contractile structure, the so-called Z-ring. This essential process involves proteins that modulate FtsZ dynamics and hence the overall Z-ring architecture.

On free subgroups in division rings

open access: yesProceedings of the American Mathematical Society, 2020
Let K K be a field, let σ \sigma be an automorphism, and let δ \delta be a σ \sigma -derivation of K K . We show that the multiplicative group of nonzero elements of the division ring D = K ( x ; σ , δ

On subgroups in division rings of type $2$

open access: yes, 2019
Let $D$ be a division ring with center $F$. We say that $D$ is a {\em division ring of type $2$} if for every two elements $x, y\in D,$ the division subring $F(x, y)$ is a finite dimensional vector space over $F$.

The MinCDJ system in Bacillus subtilis prevents minicell formation by promoting divisome disassembly. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Cell division in Bacillus subtilis takes place precisely at midcell, through the action of Noc, which prevents division from occurring over the nucleoids, and the Min system, which prevents cell division from taking place at the poles ...

On ordered division rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1954
1. Ordered groups. Suppose r is a simply ordered set and for each y in r let Ry be an additive group. Consider the set H=H(r, RY) of all vectors ( * * *, ry, * * * ) for which ry is in Ry and almost every ry is zero (i.e., the set of y's for which ry - 0 is inversely well ordered). H is a group w.r.t. (with respect to) vector addition, called the r-sum

Characterization of fuzzy neighborhood commutative division rings II

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1995
In [4] we produced a characterization of fuzzy neighborhood commutative division rings; here we present another characterization of it in a sense that we minimize the conditions so that a fuzzy neighborhood system is compatible with the commutative ...
