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

The physiological effects of breath‐holding during high‐intensity exercise
Physiological Reports, Volume 13, Issue 12, June 2025.Abstract The purpose of this study was to determine the physiological effects of breath‐holding during high‐intensity exercise. Twenty participants (age: 23 ± 4 years, 10 females) performed 20 s sprints of simultaneous arm and leg ergometry exercise, under free‐breathing (FB) and breath‐holding (BH) conditions.

Dynamically generated magnetic moment in the Wigner-function formalism
Physics Letters B, 2019 We study how the mass and magnetic moment of the quarks are dynamically generated in nonequilibrium quark matter. We derive the equal-time transport and constraint equations for the quark Wigner function in a magnetized quark model and solve them in the ...

Pion parton distribution functions with the nonrelativistic constituent quark model
Nuclear Physics B, 2023 We calculate the valence quark distribution functions of the π meson using the non-relativistic chiral constituent quark model. The π wave function is obtained by solving the two-body Schrödinger equation within the framework of constituent quark model ...

Vector-Interaction-Enhanced Bag Model
Universe, 2018 A commonly applied quark matter model in astrophysics is the thermodynamic bag model (tdBAG). The original MIT bag model approximates the effect of quark confinement, but does not explicitly account for the breaking of chiral symmetry, an important ...

Equation of state of quark-gluon plasma using a simple phenomenological model
EPJ Web of Conferences, 2018 The equation of state (EoS) of quark-gluon plasma (QGP) using a phenomenological model is studied in which finite value of quark mass is modified as effective mass.
