RD*,RK* $$ {R}_{D^{\left(*\right)}},{R}_{K^{\left(*\right)}} $$ and neutrino mass in the 2HDM-III with right-handed neutrinos

Journal of High Energy Physics, 2018
Given that the two-Higgs-doublet model of type III (2HDM-III) has the potential to address the RD* $$ {R}_{D^{\left(*\right)}} $$ anomalies while the resolution to the RK* $$ {R}_{K^{\left(*\right)}} $$ deficits requires new degrees of freedom within ...

Identification of the individual cardiac contraction threshold during high‐frame‐rate stress echocardiography

Experimental Physiology, EarlyView.
Abstract The clinical assessment of cardiovascular function during exercise using stress echocardiography is essential for accurate cardiac diagnosis. However, normal limitations of cardiac deformation responses to increasing physical exertion remain poorly understood.

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 ...

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,

Hadron Resonance Mass Spectrum and Lattice QCD Thermodynamics

, 2003
We confront lattice QCD results on the transition from the hadronic phase to the quark--gluon plasma with hadron resonance gas and percolation models. We argue that for T < T_c the equation of state derived from Monte--Carlo simulations of (2+1) quark ...

Non‐invasive assessment of integrated cardiorespiratory network dynamics after physiological stress in humans

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to develop a non‐invasive method for visualizing the cardiorespiratory network under baseline conditions and following isolated or combined exposure to hypoxia, exercise, and sleep deprivation. Twenty‐two healthy participants underwent assessments at rest and after normobaric hypoxia (FIO2${{F}_{{\mathrm{I ...

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.

Flavor changing neutral currents in top quark production and decay

, 2013
Top quark flavor changing neutral current (FCNC) interactions are highly suppressed in the Standard Model. Therefore, any large signal of FCNCs will indicate the existence of new interactions.

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

The Journal of Physiology, EarlyView.
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.

A Single Bout of Aerobic Exercise Increases Neuronal Extracellular Vesicle‐Derived Insulin Signaling Biomarkers in Adults With Cardiometabolic Risk

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
A single bout of aerobic exercise performed the night before increased some insulin signaling proteins classically involved in glucose metabolism as well as those implicated in neuronal cell growth and proliferation. We specifically observed that exercise may modulate some of these nEV‐derived biomarkers during the fasting and/or post‐glucose ingestion
