Search for CP violation in the phase space of D0 → π−π+π0 decays with the energy test

open access: yesJournal of High Energy Physics, 2023
Abstract A search for CP violation in D0 → π−π+π0 decays is reported, using pp collision data collected by the LHCb experiment from 2015 to 2018 corresponding to an integrated luminosity of 6 fb−1. An unbinned model-independent approach provides sensitivity to local CP violation within the two-dimensional phase space of the decay ...

σsregulates pLS 1 maintenance in stationary-phaseEscherichia coli [PDF]

open access: yesFEMS Microbiology Letters, 1996
We have studied the influence of sigma s on the stability and number of copies of the promiscuous plasmid pLS1 in Escherichia coli. Our results indicate that pLS1 is less stable and has a lower number of copies in a rpoS mutant than in a wild-type strain during stationary phase. This behaviour does not seem to be due to differences in the expression of

The P1 promoter of theEscherichia coli rpoHgene is utilized by σ70-RNAP or σS-RNAP depending on growth phase [PDF]

open access: yesFEMS Microbiology Letters, 2009
The P1 promoter of the Escherichia coli rpoH gene has been known as a sigma(70)-dependent promoter (RNAP). We show here that it is also recognized by sigma(S). The sigma(70) and sigma(S) RNA polymerase subunits direct transcription from the P1 promoter in the exponential and stationary growth phases, respectively, and transcriptional start sites for ...

TheEscherichia coli ftsK1mutation attenuates the induction of σS-dependent genes upon transition to stationary phase [PDF]

open access: yesFEMS Microbiology Letters, 2002
A mutation in the cell division gene ftsK causes super-induction of sigma(70)-dependent stress defense genes, such as uspA, during entry of cells into stationary phase. In contrast, we report here that stationary phase induction of sigma(S)-dependent genes, uspB and cfa, is attenuated and that sigma(S) accumulates at a lower rate in ftsK1 cells ...

Stationary phase-specific expression of theficgene inEscherichia coliK-12 is controlled by therpoSgene product (σ38) [PDF]

open access: yesFEMS Microbiology Letters, 1993
The fic gene, near pabA located at 75 min of the Escherichia coli chromosome, was previously identified as the regulatory factor of cell division. In this paper we have examined how fic gene expression is controlled during the growth cycle using a fic-lacZ protein fusion plasmid (pFL1). Its expression was induced at stationary phase while it was nearly

Thermal cycling induced stress–assisted sigma phase formation in super duplex stainless steel

open access: yesMaterials & Design, 2019
Thermal cycling induced the phase transformation originated from the physical simulation of power plant on/off operation. The effect of thermal cycling on duplex stainless steel was studied to understand its phase transformation comprehensively.

Effect of annealing temperature on the structure and properties of FeCoCrNiMo high-entropy alloy

open access: yesHigh Temperature Materials and Processes, 2022
FeCoCrNiMo high-entropy alloy was melted by vacuum arc melting. The alloys were vacuum annealed at 873, 1,073, and 1,273 K, respectively. X-ray diffractometer (XRD), scanning electron microscope (SEM), simultaneous thermal analyzer, microhardness tester,

Influence of B addition on the Mo diffusion-controlled eutectic dissolution process during homogenization of super austenitic stainless steel S31254

open access: yesJournal of Materials Research and Technology, 2023
The influence of B addition on dissolution behavior of (σ + γ)e eutectics of a 6Mo super austenitic stainless steel S31254 during the homogenization process was investigated by SEM-BSE observations combined with EDS.
