Constraining quark star properties with density-dependent interactions within the MIT bag model
European Physical Journal C: Particles and FieldsThe nature of ultra-dense matter in compact stars remains a fundamental question in astrophysics, and quark stars representing a plausible alternative to neutron stars.

Exercise echocardiography for improved assessment of diastolic filling dynamics
Experimental Physiology, Volume 110, Issue 6, Page 809-820, 1 June 2025.Abstract During exercise stress, heart rate (HR) increases to support cardiac output, which also reduces ventricular filling time. Although echocardiography is widely used to assess cardiac function, studies display conflicting data on the dynamic changes in the healthy trained and untrained heart during rest and acute exercise stress. To address these

An Interview With Peter Rousseeuw
International Statistical Review, Volume 93, Issue 1, Page 1-17, April 2025.Summary Peter J. Rousseeuw is a statistician known mainly for his work on robust statistics and cluster analysis. Among his creations are least trimmed squares regression, the minimum covariance determinant estimator, the partitioning around medoids clustering method and the silhouettes graphical display.

Visible GeV ALP from TeV Vector‐Like Leptons
Fortschritte der Physik, Volume 73, Issue 3, March 2025.Abstract A model is presented where a GeV axion‐like‐particle (ALP) is predicted in a large portion of the parameter space due to the presence of explicit Peccei–Quinn (PQ) symmetry‐breaking terms in an exotic leptonic sector. The latter provides a solution to the muon g−2$g-2$ anomaly, within the framework of the Linear Seesaw neutrino mechanism.

Scalarized hybrid neutron stars in scalar tensor gravity
European Physical Journal C: Particles and FieldsHybrid neutron stars, the compact objects consisting hadronic matter and strange quark matter, can be considered as the probes for the scalar tensor gravity. In this work, we explore the scalarization of hybrid neutron stars in the scalar tensor gravity.

On Extracting Thermal Parameters and Scenario in High‐Energy Collisions
Advances in High Energy Physics, Volume 2025, Issue 1, 2025.The inconsistent thermal parameters derived from various models in high‐energy collisions are examined. A comprehensive literature review suggests model‐independent parameters to address these inconsistencies, based on the average transverse momentum 〈pT〉 and root‐mean‐square transverse momentum pT2.

Stable strange quark matter objects with running masses and coupling constant
Nuclear Physics B, 2017 We improve our recently proposed unified description for strange quark matter (SQM) objects, in the way that analytical expressions are derived and used to calculate the distribution of particles inside an SQM object.

Asymmetric dense matter in holographic QCD
EPJ Web of Conferences, 2012 We study asymmetric dense matter in holographic QCD.We construct asymmetric dense matter by considering two quark flavor branes with dierent quark masses in a D4/D6/D6 model. To calculate the symmetry energy in nuclear matter, we consider two quarks with

Influence of dark matter on the structure of strange quark stars in one-fluid model
European Physical Journal C: Particles and FieldsThis work studies the influence of scalar dark matter on the structural properties of strange quark stars (SQS) within a one-fluid framework, considering Yukawa interactions between dark matter and quark matter.
