Novel Divisome-Associated Protein Spatially Coupling the Z-Ring with the Chromosomal Replication Terminus in Caulobacter crescentus

mBio, 2020
Cell division requires proper spatial coordination with the chromosome, which undergoes dynamic changes during chromosome replication and segregation. FtsZ is a bacterial cytoskeletal protein that assembles into the Z-ring, providing a platform to build ...

The MaoP/maoS Site-Specific System Organizes the Ori Region of the E. coli Chromosome into a Macrodomain. [PDF]

PLoS Genetics, 2016
The Ori region of bacterial genomes is segregated early in the replication cycle of bacterial chromosomes. Consequently, Ori region positioning plays a pivotal role in chromosome dynamics. The Ori region of the E.

A differential U-module algebra for U=U_q sl(2) at an even root of unity

, 2009
We show that the full matrix algebra Mat_p(C) is a U-module algebra for U = U_q sl(2), a 2p^3-dimensional quantum sl(2) group at the 2p-th root of unity.

Riemann-Hilbert approach to multi-time processes; the Airy and the Pearcey case [PDF]

, 2011
We prove that matrix Fredholm determinants related to multi-time processes can be expressed in terms of determinants of integrable kernels \`a la Its-Izergin-Korepin-Slavnov (IIKS) and hence related to suitable Riemann-Hilbert problems, thus extending ...

The role of MatP, ZapA and ZapB in chromosomal organization and dynamics inEscherichia coli [PDF]

Nucleic Acids Research, 2016
Despite extensive research over several decades, a comprehensive view of how the Escherichia coli chromosome is organized within the nucleoid, and how two daughter chromosomes segregate has yet to emerge. Here we investigate the role of the MatP, ZapA and ZapB proteins in organizing the replication terminus (Ter) region and in the chromosomal ...

Multi-Faceted Adaptive Token Pruning for Efficient Remote Sensing Image Segmentation

Remote Sensing
Global context information is essential for semantic segmentation of remote sensing (RS) images. Due to their remarkable capability to capture global context information and model long-range dependencies, vision transformers have demonstrated great ...

A novel model for evaluating the strain-controlled fracture behavior in strip martensite steel

Journal of Materials Research and Technology
To address the challenges posed by the limitations of the Hall-Petch equation for strip martensite steel and the complex relationship between its macro-plasticity/toughness (MATP) and micro-plasticity/toughness (MITP), a composite parameter model (CPM ...

Fast growth conditions uncouple the final stages of chromosome segregation and cell division in Escherichia coli. [PDF]

PLoS Genetics, 2017
Homologous recombination between the circular chromosomes of bacteria can generate chromosome dimers. They are resolved by a recombination event at a specific site in the replication terminus of chromosomes, dif, by dedicated tyrosine recombinases.
