Divisibility and duo-rings

Rendiconti del Seminario Matematico della Università di Padova, 2020
This paper investigates the projective dimension of the maximal right ring of quotients Q^r(R) of a right non-singular ring R. Our discussion addresses the question under which conditions pd (Q) \leq 1 guarantees that the module

Free SepF interferes with recruitment of late cell division proteins

Scientific Reports, 2017
The conserved cell division protein SepF aligns polymers of FtsZ, the key cell division protein in bacteria, during synthesis of the (Fts)Z-ring at midcell, the first stage in cytokinesis.

Three-Dimensional Superresolution Imaging of the FtsZ Ring during Cell Division of the Cyanobacterium Prochlorococcus

mBio, 2017
Superresolution imaging has revealed subcellular structures and protein interactions in many organisms. However, superresolution microscopy with lateral resolution better than 100 nm has not been achieved in photosynthetic cells due to the interference ...

Quantitative analysis of cytokinesis in situ during C. elegans postembryonic development. [PDF]

PLoS ONE, 2014
The physical separation of a cell into two daughter cells during cytokinesis requires cell-intrinsic shape changes driven by a contractile ring. However, in vivo, cells interact with their environment, which includes other cells.

Co-Hydroprocessing of Fossil Middle Distillate and Bio-Derived Durene-Rich Heavy Ends under Hydrotreating Conditions

Reactions, 2023
Methanol-to-gasoline (MTG) and dimethyl ether-to-gasoline (DTG), as industrially approved processes for producing greenhouse gas-neutral gasoline, yield byproducts rich in heavy mono-ring aromatics such as 1,2,4,5-tetramethylbenzene (durene).

A note on maps preserving products of matrices

AIMS Mathematics
Let $ D $ be a division ring such that either char$ (D)\neq 2, 3 $ or $ D $ is not a field and char$ (D)\neq 2 $. Let $ R = M_n(D) $ be the matrix ring over $ D $, where $ n > 1 $. Let $ m, k $ be fixed invertible elements in $ R $.

8x14Gb/s ring WDM modulator array with integrated tungsten heaters and Ge monitor photodetectors [PDF]

, 2014
An 8x14Gb/s wavelength-division multiplexed Si ring modulator array is presented with uniform channel performance. Tungsten heaters and Ge monitor photodetectors at the ring modulator drop ports are co-integrated to track and control the modulation ...

1-Pbps orbital angular momentum fibre-optic transmission

Light: Science & Applications, 2022
A 1-Pbps orbital-angular-momentum fibre-optic transmission system that combines space-division multiplexing and wavelength-division multiplexing in a 34 km 7-core ring-core fibre is demonstrated utilizing low-complexity 4 × 4 MIMO equalization.

Trapping of a spiral-like intermediate of the bacterial cytokinetic protein FtsZ

, 2006
The earliest stage in bacterial cell division is the formation of a ring, composed of the tubulin-like protein FtsZ, at the division site. Tight spatial and temporal regulation of Z-ring formation is required to ensure that division occurs precisely at ...

Dense Space-Division Multiplexing Exploiting Multi-Ring Perfect Vortex

Sensors, 2023
Vortex beams carrying orbital angular momentum (OAM) have gained much interest in optical communications because they can be used to expand the number of multiplexing channels and greatly improve the transmission capacity.
