Scene Text Image Super-Resolution Reconstruction Based on Dual-Branched Sequence Residual Attention [PDF]

Jisuanji gongcheng
This paper proposes Dual-branch Sequence Residual Attention for Super-resolution Reconstruction Network (DSRASRN) to address the drawbacks of loss of detail information and edge blurring in text images reconstructed by existing scene text image super ...

The Active Sulfate-Reducing Microbial Community in Littoral Sediment of Oligotrophic Lake Constance

Frontiers in Microbiology, 2019
Active sulfate-reducing microorganisms (SRM) in freshwater sediments are under-examined, despite the well-documented cryptic sulfur cycle occurring in these low-sulfate habitats.

pH mediated assemblage of carbon, nitrogen, and sulfur related microbial communities in petroleum reservoirs

Frontiers in Microbiology, 2022
Microorganisms are the core drivers of biogeochemistry processes in petroleum reservoirs and have been widely used to enhance petroleum recovery. However, systematic information about the microbial communities related to the C-N-S cycle in petroleum ...

Phylogenetic diversity and distribution of dissimilatory sulfite reductase genes from deep-sea sediment cores [PDF]

, 2007
The diversity and distribution of sulfate-reducing prokaryotes (SRP) was investigated in the Nankai Trough sediments of off-central Japan by exploring the diversity of a functional gene, dissimilatory sulfite reductase (dsrAB).

Multiple lateral transfers of dissimilatory sulfite reductase genes between major lineages of sulfate-reducing prokaryotes [PDF]

, 2001
A large fragment of the dissimilatory sulfite reductase genes (dsrAB) was PCR amplified and fully sequenced from 30 reference strains representing all recognized lineages of sulfate-reducing bacteria.

Activity and phylogenetic diversity of sulfate-reducing microorganisms in low-temperature subsurface fluids within the upper oceanic crust

Frontiers in Microbiology, 2015
The basaltic ocean crust is the largest aquifer system on Earth, yet the rates of biological activity in this environment are unknown. Low-temperature (

Genomic insight of sulfate reducing bacterial genus Desulfofaba reveals their metabolic versatility in biogeochemical cycling

BMC Genomics, 2023
Background Sulfate-reducing bacteria (SRB) drive the ocean sulfur and carbon cycling. They constitute a diverse phylogenetic and physiological group and are widely distributed in anoxic marine environments.

Protein dynamics and molecular motions study in relation tomolecular interaction between DsrAB and DsrC proteins from sulfur oxidizer proteobacteria Allochromatium vinosum

, 2020
The gamma-proteobacteria Allochromatium vinosum DSM 180T (A. vinosum) encodes the sulfur oxidizing dsr operon comprising of 15 genes. Dsr proteins are involved in oxidation of sulfur globules produced as an obligatory intermediate during the sulfur ...

Cytoplasmic sulfurtransferases in the purple sulfur bacterium Allochromatium vinosum: evidence for sulfur transfer from DsrEFH to DsrC. [PDF]

PLoS ONE, 2012
While the importance of sulfur transfer reactions is well established for a number of biosynthetic pathways, evidence has only started to emerge that sulfurtransferases may also be major players in sulfur-based microbial energy metabolism.
