The mixed phase quark core in massive hybrid stars

European Physical Journal C: Particles and Fields
We investigate the properties of hybrid star and the mixed phase core to explore the radius ratio of the mixed phase in hybrid star. In the context of observed massive neutron stars (NSs), we examine the internal structure, phase transitions, and the ...

Quark-Nova Explosion inside a Collapsar: Application to Gamma Ray Bursts

Advances in Astronomy, 2009
If a quark-nova occurs inside a collapsar, the interaction between the quark-nova ejecta (relativistic iron-rich chunks) and the collapsar envelope leads to features indicative of those observed in Gamma Ray Bursts.

QUARK-CLUSTER STARS: THE STRUCTURE

International Journal of Modern Physics: Conference Series, 2013
The nature of pulsar-like compact stars is still in controversy although the first pulsar was found more than 40 years ago. Generally speaking, conventional neutron stars and non-mainstream quark stars are two types of models to describe the inner structure of pulsars, with the former composed mainly of hadrons and the latter of a peculiar kind of ...

Peri‐operative rehabilitation in patients undergoing elective cardiac valve surgery: a randomised controlled trial

Anaesthesia, EarlyView.
Summary Introduction Patients with valvular heart disease are at high risk of postoperative pulmonary complications, which contribute to morbidity and mortality. However, few studies have focused specifically on peri‐operative rehabilitation in this patient population.

Nonperturbative models of quark stars in f(R) gravity

Physics Letters B, 2015
Quark star models with realistic equation of state in nonperturbative f(R) gravity are considered. The mass-radius relation for f(R)=R+αR2 model is obtained.

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 ...

New mass limit of a strange star admitting a colour flavor locked equation of state

European Physical Journal C: Particles and Fields, 2023
A class of strange stars is analysed in the present article in hydrostatic equilibrium, whose state is defined by a CFL phase equation of state. We have compared our results with those obtained from the MIT equation of state for strange quark matter ...

Quark formation and phenomenology in binary neutron-star mergers using V-QCD

SciPost Physics, 2022
Using full 3+1 dimensional general-relativistic hydrodynamic simulations of equal- and unequal-mass neutron-star binaries with properties that are consistent with those inferred from the inspiral of GW170817, we perform a detailed study of the quark ...

Impact of exercise training on tumour‐infiltrating T cells in human prostate cancer: A secondary analysis of a randomized controlled trial (PRO‐TEST)

Experimental Physiology, EarlyView.
Abstract Exercise training reduces tumour growth by increasing tumour‐infiltrating T‐cell density in preclinical models. However, it remains unknown whether exercise training can modify intratumoural T cells in humans.The aim of this study was to compare the effects of an exercise training intervention versus control on human prostate intratumoural T ...

Commuting by bicycle (vs. by car) is associated with improved aerobic power, microvascular function and diminished CO2 output in the atmosphere

Experimental Physiology, EarlyView.
Abstract The study investigated whether bicycle compared with car commuting, over relatively small distances, has positive effects on physiological variables, cardiometabolic fitness and CO2 output in the atmosphere. Bike Commuters (11 M, 15 F; age [median value (interquartile range)] 51.5 (38.3–56.8) years; body mass index [BMI] 22.8 (21.0–24.1) kg m ...
