Signals of the QCD Phase Transition in the Heavens [PDF]

open access: yes, 2007
The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.

Baryon asymmetry from left-right phase transition

open access: yesPhysics Letters B, 2020
We extend the standard model fermions by a mirror copy to realize a left-right symmetry. During a strongly first order phase transition of the spontaneous left-right symmetry breaking, the CP-violating reflections of the mirror fermions off the mirror ...

The earliest phase transition? [PDF]

open access: yesNuclear Physics B, 2000
The question of a phase transition in exiting the Planck epoch of the early universe is addressed. An order parameter is proposed to help decide the issue, and estimates are made concerning its behavior. Our analysis is suggestive that a phase transition occurred.

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.

A continuum model for the dynamics of the phase transition from slow-wave sleep to REM sleep [PDF]

open access: yes, 2010
Previous studies have shown that activated cortical states (awake and rapid eye-movement (REM) sleep), are associated with increased cholinergic input into the cerebral cortex.

A Phase Transition in Minesweeper

open access: yesCoRR, 2020
We study the average-case complexity of the classic Minesweeper game in which players deduce the locations of mines on a two-dimensional lattice. Playing Minesweeper is known to be co-NP-complete. We show empirically that Minesweeper exhibits a phase transition analogous to the well-studied SAT phase transition.

Association Between Individualized Education for Kidney Replacement Therapy Modality Selection and Peritoneal Dialysis Initiation: A Cross‐Sectional Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Peritoneal dialysis (PD) is an established home‐based kidney replacement therapy (KRT), but its uptake remains low in Japan. We evaluated whether individualized education in a dedicated outpatient clinic was associated with the initiation of PD.

Range expansion with mutation and selection: dynamical phase transition in a two-species Eden model [PDF]

open access: yes, 2011
The colonization of unoccupied territory by invading species, known as range expansion, is a spatially heterogeneous non-equilibrium growth process.

Effects of phase-transition heat on fracture temperature in self-propping phase-transition fracturing technology

open access: yesPetroleum Exploration and Development
The thermal flux curve of phase-transition fluid (PF) was tested using differential scanning calorimetry, based on which a reaction kinetics model was established to reflect the relationship between phase transition conversion rate, temperature and time.

Magnetoresistance Features at the Magnetic Field-Induced Phase Transition in FeRh Thin Films

open access: yesJournal of Mathematical and Fundamental Sciences, 2023
The causes of the appearance of first-order magnetic phase transitions remain a mystery. FeRh alloy is a classical material where a first-order magnetic phase transition occurs.
