Effect of hypoxia on muscle activation at equivalent absolute and relative intensity during incremental and constant load exercise to task failure

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1933-1947, 1 April 2026.
Abstract We examined the impact of moderate hypoxia (HYPO) on muscle activation during incremental exercise matched for both absolute and equivalent relative intensity. Fifteen active subjects (10 males, 5 females) completed two ramp incremental test and two step tests in normoxia (NORM; FiO2${F_{{\mathrm{i}}{{\mathrm{O}}_2}}}$ = 0.209) and HYPO (FiO2${

Parity doubling as a tool for right-handed current searches

open access: yesJournal of High Energy Physics, 2018
The V-A structure of the weak interactions leads to definite amplitude hierarchies in exclusive heavy-to-light decays mediated by b → (d, s)γ and b→d,sℓℓ¯ $$ b\to \left(d,\ s\right)\ell \overline{\ell} $$. However, the extraction of right-handed currents

Females exhibit greater cardiac volume reductions with expiratory muscle loading during submaximal exercise compared to males

open access: yesThe Journal of Physiology, Volume 604, Issue 7, Page 3175-3200, 1 April 2026.
Abstract figure legend Intrathoracic pressure (ITP) manipulation during submaximal exercise reveals load‐ and sex‐specific cardiac volume responses. Inspiratory loading increased oesophageal pressure swings and the work of breathing (Wb) but did not alter stroke volume (SV) or ventricular volumes in males or females.

ΔA CP within the Standard Model and beyond

open access: yesJournal of High Energy Physics, 2019
In light of the recent LHCb observation of CP violation in the charm sector, we review standard model (SM) predictions in the charm sector and in particular for ΔA CP.

Jet quenching of massive quarks in a nuclear medium

open access: yes, 2004
Utilizing the generalized factorization of twist-4 processes, we derive the modified heavy quark fragmentation function after considering the gluon radiation induced by multiple scattering in DIS.

Metabolic, V̇O2 kinetics, and muscle oxygenation responses at and above maximal lactate steady state in trained male rowers

open access: yesPhysiological Reports, Volume 14, Issue 8, April 2026.
Abstract This study aimed to compare physiological responses during rowing ergometer exercise at the maximal lactate steady state (MLSS) and 5% above the MLSS (MLSS+5%). Blood lactate concentration (BLC), oxygen uptake (V̇O2) kinetics, heart rate (HR), and muscle oxygenation (deoxygenated hemoglobin [HHb] and tissue saturation index [TSI]) of the ...

Experimental Highlights: Heavy Quark Physics in Heavy-Ion Collisions at RHIC

open access: yesEPJ Web of Conferences, 2017
The discovery at RHIC of large high-pT suppression and flow of electrons from heavy quarks flavors have altered our view of the hot and dense matter formed in central Au + Au collisions at √sNN = 200 GeV.

Two-loop integrals for CP-even heavy quarkonium production and decays: elliptic sectors

open access: yesJournal of High Energy Physics, 2018
By employing the differential equations, we compute analytically the elliptic sectors of two-loop master integrals appearing in the NNLO QCD corrections to CP-even\ heavy quarkonium exclusive production and decays, which turns out to be the last and ...

SU(3) F analysis for beauty baryon decays

open access: yesJournal of High Energy Physics, 2020
We perform a general SU(3)F analysis of b → c c ¯ s d $$ b\to c\overline{c}s(d) $$ decays of members of the beauty baryon antitriplet to a member of the light baryon octet and a singlet. Under several reasonable assumptions we found A Ξ b 0 → Λ S / A Ξ b
