Dense quark matter with chiral and isospin imbalance: NJL-model consideration

open access: yesEPJ Web of Conferences, 2018
Isospin asymmetry is the well-known property of dense quark matter, which exists in the compact stars and is produced in heavy ion collisions. On the other hand, the chiral imbalance between left- and right- handed quarks is another highly anticipated ...

Is It Safe to Reduce Inhaled Corticosteroid Dose in Severe Asthma Patients Receiving Biologic Therapy?

open access: yesClinical and Translational Allergy, Volume 16, Issue 10, October 2026.
ABSTRACT Background Biologic therapies can control severe asthma and may modify its natural history beyond symptom control. However, step‐down is not standardized, and its safety has not been clearly established. Methods This single‐center retrospective cohort study reviewed adults with severe asthma on biologics (January 2019–May 2024).

Polynomial Preconditioning for Indefinite Matrices

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT Polynomial preconditioning is an important tool in solving large linear systems and eigenvalue problems. A polynomial from GMRES can be used to precondition restarted GMRES and restarted Arnoldi. Here we give methods for indefinite matrices that make polynomial preconditioning more generally applicable. The new techniques include balancing the

Quarkonium states in an anisotropic quark-gluon plasma [PDF]

open access: yes, 2009
In this work we study the properties of quarkonium states in a quark-gluon plasma which, due to expansion and non-zero viscosity, exhibits a local anisotropy in momentum space.

NUCLEAR MATTER AND THE TRANSITION TO QUARK MATTER IN AN EFFECTIVE QUARK THEORY [PDF]

open access: yes, 2020
We use an effective chiral quark theory to incorporate the nucleon structure into the description of nuclear matter, and use the resulting equation of state to discuss the EMC effect in nuclear matter.

Instanton corrections to the MSTB Kink mass

open access: yesJournal of High Energy Physics
The Montonen-Sarker-Trullinger-Bishop (MSTB) model enjoys two classically degenerate kink solutions in the same topological sector. We construct the instanton that interpolates between them and argue that the two lowest lying Hamiltonian eigenstates in ...

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

open access: yesOikos, Volume 2026, Issue 10, October 2026.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...

Properties of strange quark matter and strange quark stars

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
A Polyakov chiral $$\text {SU(3)}$$ SU(3) quark mean-field (PCQMF) model is applied to study the properties of strange quark matter (SQM) and strange quark star (SQS) in $$\beta $$ β -equilibrium.

Quark spin polarization in high density quark matter

open access: yesEPJ Web of Conferences, 2014
It is shown that there exists a possibility of spontaneous spin polarization in high density symmetric quark matter under the tensor-type four-point interaction between quarks in the Nambu-Jona-Lasinio model.
