Differential Regulation of CsrC and CsrB by CRP-cAMP in Salmonella enterica
Frontiers in Microbiology, 2020 Post-transcriptional regulation mediated by regulatory small RNAs (sRNAs) has risen as a key player in fine-tuning gene expression in response to environmental stimuli.

Logarithmic current fluctuations in non-equilibrium quantum spin chains [PDF]
, 2008 We study zero-temperature quantum spin chains which are characterized by a non-vanishing current. For the XX model starting from the initial state |... + + + - - - ...> we derive an exact expression for the variance of the total spin current.

An expression index for Affymetrix GeneChips based on the generalized logarithm [PDF]
Bioinformatics, 2005 Affymetrix GeneChip high-density oligonucleotide arrays interrogate a single transcript using multiple short 25mer probes. Usually, a necessary step in the analysis of experiments using these GeneChips is to summarize each of these probe sets into a single expression index that can then be used for determining differential expression, for ...

RpoN Promotes Pseudomonas aeruginosa Survival in the Presence of Tobramycin
Frontiers in Microbiology, 2017 Pseudomonas aeruginosa has developed diverse strategies to respond and adapt to antibiotic stress. Among the factors that modulate survival in the presence of antibiotics, alternative sigma factors play an important role.

Expression of RecF and GyrB Genes in a Low Ciprofloxacin-resistant Escherichia coli Mutant [PDF]
Biological Journal of Microorganism, 2018 Introduction: Replication and recombination are two fundamental cellular processes. GyrB and RecF are two proteins that are involved in these processes, respectively. GyrB is a subunit of DNA gyrase, the enzyme maintains negative supercoil in genomic DNA.

Logarithmic correction to the Bekenstein-Hawking entropy of the BTZ black hole [PDF]
, 2001 We derive an exact expression for the partition function of the Euclidean BTZ black hole. Using this, we show that for a black hole with large horizon area, the correction to the Bekenstein-Hawking entropy is $-3/2 log(Area)$, in agreement with that for ...
