B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the NMSSM with the Flavour Expansion Theorem

Journal of High Energy Physics, 2019
In this paper, motivated by the observation that the Standard Model predictions are now above the experimental data for the mass difference ΔM s(d), we perform a detailed study of B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the

Sex and performance‐level differences in aerobic and haematological parameters among elite ski mountaineering athletes

Experimental Physiology, EarlyView.
Abstract Ski mountaineering (SkiMo) is a new Olympic sport with extreme endurance demands and altitude exposure. Previous studies have focused on traditional cardiorespiratory variables, such as maximal oxygen consumption (V̇O2max${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$) or ventilatory thresholds, but, to our knowledge, did not report ...

Mass splitting and spin alignment for $$\phi $$ ϕ mesons in a magnetic field in NJL model

European Physical Journal C: Particles and Fields
Based on the Nambu–Jona–Lasinio (NJL) model, we develop a framework for calculating the spin alignment of vector mesons and applied it to study $$\phi $$ ϕ mesons in a magnetic field.

Potential analysis of holographic Schwinger effect in the magnetized background

European Physical Journal C: Particles and Fields, 2020
We study the holographic Schwinger effect with magnetic field at RHIC and LHC energies by using the AdS/CFT correspondence. We consider both weak and strong magnetic field cases with $$B\ll T^2$$ B≪T2 and $$B\gg T^2$$ B≫T2 solutions respectively. Firstly,

A new method for bedside determination of effective lung volume and functional residual capacity

Experimental Physiology, EarlyView.
Abstract Established methods of measuring functional residual capacity (FRC) involve sophisticated equipment and elaborate procedures. Here we present a new method based on CO2 rebreathing that has a simple fast procedure and only requires end‐tidal CO2 monitoring. Ten healthy subjects with diverse anthropometric and respiratory parameters were studied

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

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

Experimental Physiology, EarlyView.
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${

Acute ketone monoester ingestion lowers resting cerebral blood flow: a randomized cross‐over trial

The Journal of Physiology, EarlyView.
Abstract figure legend This double‐blind, placebo‐controlled, randomized cross‐over trial investigated the effects of ketone monoester (KME) ingestion on resting cerebral blood flow (CBF) in young adults. We demonstrate that KME supplementation lowers CBF in a dose‐dependent manner over 2‐houra post‐ingestion, whereas CBF remained unchanged following ...

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

The Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...
