Boiling of strange-quark matter [PDF]

open access: yesPhysical Review D, 1991
Boiling of strange-quark matter is studied assuming baryon chemical equilibrium between a quark phase described by the bag model, and a hadron phase described by Walecka's mean-field theory. Boiling of quark nuggets at high temperatures is shown to be much less efficient than previously believed. Thus quark nuggets with large baryon numbers may survive

Persistence of fatigue in the absence of pathophysiological mechanisms in some patients more than 2 years after the original SARS‐CoV‐2 infection

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 1413-1428, 1 March 2026.
Abstract Following an acute infection with severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2), a substantial percentage of patients report the persistence of debilitating symptoms, often grouped in a syndrome termed ‘long COVID’. We sought to identify potential pathophysiological mechanisms responsible for the persistence, in some long COVID ...

Quark description of nuclear matter

open access: yes, 2000
We discuss the role of an adjoint chiral condensate for color superconducting quark matter. Its presence leads to color-flavor locking in two-flavor quark matter.

The Bioavailability of Xanthohumol in Humans and the Influence of Formulation and Dose: Randomized Controlled Trial Data

open access: yesMolecular Nutrition &Food Research, Volume 70, Issue 4, 26 February 2026.
The effects of two different doses of micellar and native xanthohumol on plasma kinetics were investigated in 12 healthy men and women. Micellization significantly improved the bioavailability of xanthohumol. A subsequent placebo‐controlled study on the acute effects of xanthohumol on resting energy expenditure, blood pressure, and heart rate in 16 ...

Functional renormalization group study of the quark-meson model with $$\omega $$ ω and $$\rho $$ ρ vector mesons

open access: yesEuropean Physical Journal C: Particles and Fields
We employ the functional renormalization group flow equations to investigate the phase structure of the two-flavor quark-meson model in the presence of a finite isospin chemical potential, incorporating interactions with omega and rho vector mesons.

Neutron Star Interiors and Topology Change

open access: yesAdvances in Mathematical Physics, 2013
Quark matter is believed to exist in the center of neutron stars. A combined model consisting of quark matter and ordinary matter is used to show that the extreme conditions existing in the center could result in a topology change, that is, in the ...

QCD Kondo excitons

open access: yesPhysical Review Research, 2020
The quantum chromodynamics (QCD) Kondo effect is a quantum phenomenon in which heavy quarks (c,b) exist as impurity particles in quark matter composed of light quarks (u,d,s) at extremely high density.

Nutritional approach in a growing Jack Russell terrier with gall bladder agenesis

open access: yesVeterinary Record Case Reports, Volume 14, Issue 1, February 2026.
Abstract An asymptomatic male Jack Russell terrier diagnosed at the age of 18 weeks with congenital gall bladder agenesis, confirmed by computed tomography scan, after finding abnormally high values for liver enzymes in a routine blood count. Treatment with liver‐protective agents S‐adenosylmethionine and ursodeoxycholic acid was initiated. At 6 months

Stellar matter in the Quark-Meson-Coupling Model with neutrino trapping

open access: yes, 2003
The properties of hybrid stars formed by hadronic and quark matter in $\beta$-equilibrium are described by appropriate equations of state (EoS) in the framework of the quark meson coupling (QMC) model.

Statistical mechanics of semi-classical colored objects [PDF]

open access: yes, 2005
A microscopic model of deconfined matter based on color interactions between semi-classical quarks is studied. A hadronization mechanism is imposed to examine the properties and the disassembly of a thermalized quark plasma and to investigate the ...
