Phases of Hadron-Quark Matter in (Proto) Neutron Stars

Universe, 2019
In the first part of this paper, we investigate the possible existence of a structured hadron-quark mixed phase in the cores of neutron stars. This phase, referred to as the hadron-quark pasta phase, consists of spherical blob, rod, and slab rare phase ...

Disproportional ventilatory response to incremental exercise in individuals with cerebral palsy

Developmental Medicine &Child Neurology, EarlyView.
Individuals with cerebral palsy demonstrate a disproportionate ventilatory response during incremental exercise. Compared with typically developing peers, respiratory frequency increases earlier and at comparable exercise intensities, contributing to higher perceived exertion and reduced ventilatory efficiency. At task failure, respiratory frequency is

A 4 modular flavour model of quark mass hierarchies close to the fixed point τ = i∞

Journal of High Energy Physics, 2023
We study the possibility to generate the quark mass hierarchies as well as the CKM quark mixing and CP violation without fine-tuning in a quark flavour model with modular A 4 symmetry.

Psychological responses to interval and continuous exercise in people living with HIV: A single‐blind, counterbalanced, crossover study

HIV Medicine, EarlyView.
Abstract Aim This study compared acute psychological responses to a single session of low‐volume high‐intensity interval exercise (HIIE‐LV), high‐volume high‐intensity interval exercise (HIIE‐HV), and moderate‐intensity continuous exercise (MICE) in people living with HIV, and healthy controls using a randomized, counterbalanced crossover design ...

Spectroscopy of higher bottomonia

EPJ Web of Conferences, 2015
In this contribution, we discuss our recent unquenched quark model results for the spectrum of bb̄ mesons with self energy corrections, due to the coupling to the meson-meson continuum.

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 ...

Study of the Ground-State Energies of Some Nuclei Using Hybrid Model

Advances in High Energy Physics, 2021
The quark-quark (QQ) interaction as a perturbed term to the nucleon-nucleon interaction (NN) without any coupling between them is studied in a hybrid model. This model is used to calculate the ground-state energies of 2H1 and 4He2 nuclei.

On the Naturalistic Grounds of Grounding

Ratio, EarlyView.
ABSTRACT This paper examines whether grounding can be naturalized. We adopt a tripartite framework—Ocat (scientific catalogue of existents), Otyp (ontological types), and metaphysics (natures/modal profiles)—and show that classifying as such the relata of putative grounding claims forces a dilemma.

Impact of a 12‐week high‐intensity interval training intervention on cardiac structure and function after COVID‐19 at 12‐month follow‐up

Experimental Physiology, EarlyView.
Abstract In patients previously hospitalised for COVID‐19, a 12‐week high‐intensity interval training (HIIT) intervention has previously been shown to increase left ventricular mass (LVM) immediately after the intervention. In the present study, we examined the effects of the same HIIT scheme on LVM, pulmonary diffusing capacity, symptom severity and ...

Understanding pentaquarks with various quark models

Physics Letters B, 2004
The pentaquark state recently discovered has been studied with three quark models which either fit the nucleon spin structure or the $NN$ scattering. A minimum $ ^+$ mass of 1620 MeV is obtained both for the ${1/2}^\pm$ state. The mixing of various color structure configurations, which would reduce the mass of the penta-quark state, should be taking ...
