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

open access: yesHIV 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 ...

Understanding pentaquarks with various quark models

open access: yesPhysics 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 ...

The Role of Brain Structure in Explaining Physical Functioning in Male Veterans With Impaired Kidney Function

open access: yesJournal of the American Geriatrics Society, EarlyView.
Brain structure as a mediator of the relationship of impaired kidney function and physical function. ABSTRACT Background Older adults with chronic kidney disease (CKD) experience deficits in physical function and cardiorespiratory fitness at higher rates than older adults without impaired renal function.

Pion parton distribution functions with the nonrelativistic constituent quark model

open access: yesNuclear 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 ...

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

open access: yesExperimental 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 ...

The dual quark models

open access: yes, 2012
We briefly recall the historical environment around our 1971 and 1975 constructions of current-algebraic internal symmetry on the open string. These constructions included the introduction of world sheet fermions, the independent discovery of affine Lie algebra in physics (level one of affine su(3)), the first examples of the affine-Sugawara and coset ...

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

open access: yesExperimental 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 ...

Search for single production of vector-like quarks decaying into Wb in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
A search for singly produced vector-like quarks Q, where Q can be either a T quark with charge +2/3 or a Y quark with charge −4/3, is performed in proton–proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity

Tumbling top-quark condensate model [PDF]

open access: yesPhysical Review D, 1992
We propose a renormalizable model with no fundamental scalars which breaks itself in the manner of a "tumbling" gauge theory down to the standard model with a top-quark condensate. Because of anomaly cancellation requirements, this model contains two color sextet fermions (quixes), which are vector-like with respect to the standard model gauge group ...
