An insight into oversaturated deformation-induced sigma precipitation in Super304H austenitic stainless steel

open access: yesMaterials & Design, 2019
A new mechanism of the deformation-promoted precipitation of the sigma phase during aging at 650 °C in nanocrystallized Super304H austenitic stainless steel was proposed for its extremely early nucleation and subsequently fast growth.

Synthesis of the stationary-phase sigma factor sigma s is positively regulated by ppGpp [PDF]

open access: yesJournal of Bacteriology, 1993
Strains of Escherichia coli which lack detectable guanosine 3',5'-bispyrophosphate (ppGpp) display a pleiotropic phenotype that in some respects resembles that of rpoS (katF) mutants. This led us to examine whether ppGpp is a positive regulator of sigma s synthesis.

Holographic p-wave superconductivity from higher derivative theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We construct a holographic SU(2) p-wave superconductor model with Weyl corrections. The high derivative (HD) terms do not seem to spoil the generation of the p-wave superconducting phase. We mainly study the properties of AC conductivity, which is absent

Totally asymmetric exclusion process with long-range hopping

open access: yes, 2006
Generalization of the one-dimensional totally asymmetric exclusion process (TASEP) with open boundary conditions in which particles are allowed to jump $l$ sites ahead with the probability $p_l\sim 1/l^{\sigma+1}$ is studied by Monte Carlo simulations ...

Thermodynamic Simulation of Equilibrium Solidification and Precipitation of CW12MW and CW6MC Cast Nickel-based Alloys

open access: yesTeshugang, 2023
Thermo-Calc (TC)thermodynamic calculation software and TCNI10 professional nickel-based alloy database were used to calculate and analyze the phase transition paths during the equilibrium solidification and cooling process of CW12MW and CW6MC cast nickel-

Single-site approximation for reaction-diffusion processes

open access: yes, 2006
We consider the branching and annihilating random walk $A\to 2A$ and $2A\to 0$ with reaction rates $\sigma$ and $\lambda$, respectively, and hopping rate $D$, and study the phase diagram in the $(\lambda/D,\sigma/D)$ plane.

Measurement of $\bar{\nu}_{\mu}$ and $\nu_{\mu}$ charged current inclusive cross sections and their ratio with the T2K off-axis near detector [PDF]

open access: yes, 2017
We report a measurement of cross section $\sigma(\nu_{\mu}+{\rm nucleus}\rightarrow\mu^{-}+X)$ and the first measurements of the cross section $\sigma(\bar{\nu}_{\mu}+{\rm nucleus}\rightarrow\mu^{+}+X)$ and their ratio $R(\frac{\sigma(\bar \nu)}{\sigma ...
