Corrosion Cases and Cause Analysis of Steam Tubine Low PressureCylinder blades for the Super - Critical Unit [PDF]

open access: yesCailiao Baohu, 2021
It was generally found that the low pressure cylinder blades of steam turbines had pitting corrosion during the overhaul of super-critical units. In order to analyze the causes of low pressure cylinder blades pitting corrosion, the corrosion products ...

Critical phenomena and functional renormalization group

open access: yesHe jishu, 2023
Recent progress in studies on quantum chromodynamics (QCD) phase transition and related critical phenomena within the functional renormalization group (fRG) approach were reviewed, including the nonperturbative critical exponents and baryon number ...

Fixed point theorem combined with variational methods for a class of nonlinear impulsive fractional problems with derivative dependence

open access: yesAIMS Mathematics, 2021
In this article, we deal with a class of nonlinear impulsive problems of fractional-order in which nonlinearity is due to the fractional-order derivative term.

Transport model study of conserved charge fluctuations and QCD phase transition in heavy-ion collisions

open access: yesHe jishu, 2023
The RHIC-STAR (Relativistic Heavy Ion Collider-Solenoid Tracker at RHIC) experiments have measured the cumulants of net-proton (a proxy for net-baryon), net-charge, and net-kaon (proxy of net-strangeness) multiplicity distributions in Au+Au collisions at

The effective QCD phase diagram and the critical end point

open access: yesNuclear Physics B, 2015
We study the QCD phase diagram on the temperature T and quark chemical potential μ plane, modeling the strong interactions with the linear sigma model coupled to quarks.

Dependence of the crossover zone on the regularization method in the two-flavor Nambu–Jona-Lasinio model

open access: yesOpen Physics, 2020
In this article, we study the two-flavor Nambu and Jona-Lasinio (NJL) phase diagrams on the T–μ plane through three regularization methods. In one of these, we introduce an infrared three-momentum cutoff in addition to the usual ultraviolet ...

New approach to lattice QCD at finite density; results for the critical end point on coarse lattices

open access: yesJournal of High Energy Physics, 2020
All approaches currently used to study finite baryon density lattice QCD suffer from uncontrolled systematic uncertainties in addition to the well-known sign problem. We formulate and test an algorithm, sign reweighting, that works directly at finite μ =

Comprehensive Evaluation of End-Point Free Energy Techniques in Carboxylated-Pillar[6]arene Host-Guest Binding: IV. The QM Treatment, GB Models and the Multi-Trajectory Extension

open access: yesLiquids, 2023
Due to the similarity of host–guest complexes and protein–ligand and protein–protein assemblies, computational tools for protein–drug complexes are commonly applied in host–guest binding.

Ferroelectric nematic -- isotropic critical end point

open access: yes, 2023
A critical end point above which an isotropic phase continuously evolves into a polar (ferroelectric) nematic phase with an increasing electric field is found in a ferroelectric nematic liquid crystalline material. The critical end point is approximately 30 K above the zero-field transition temperature from the isotropic to nematic phase and at an ...

Evolution toward Quantum Critical End Point in UGe2 [PDF]

open access: yesJournal of the Physical Society of Japan, 2011
We report on Hall resistivity and electrical resistivity measurements under pressure and magnetic field in UGe_2 with ferromagnetic (FM) tricriticality. The Hall resistivity sensitively detects the first order metamagnetic transition from a paramagnetic (PM) phase to a FM phase in a large pressure range almost up to the quantum critical end point (QCEP)
