Nonperturbative results on the quark-gluon vertex

, 2013
We present analytical and numerical results for the Dirac form factor of the quark-gluon vertex in the quark symmetric limit, where the incoming and outgoing quark momenta have the same magnitude but opposite sign.

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 ...

Searching for Charged Higgs Boson in Polarized Top Quark

, 2013
The charged Higgs boson is quite common in many new physics models. In this study we examine the potential of observing a heavy charged Higgs boson in its decay mode of top-quark and bottom-quark in the Type-II Two-Higgs-Doublet-Model. In this model, the

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 ...

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.

Triple-quark elastic scatterings and thermalization

, 2005
Triple-quark elastic scattering amplitudes from perturbative QCD are first calculated and then used in a transport equation to study the thermalization of quark matter.

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 ...

Quark condensate for various heavy flavors

, 2012
The quark condensate is calculated within the world-line effective-action formalism, by using for the Wilson loop an ansatz provided by the stochastic vacuum model. Starting with the relation between the quark and the gluon condensates in the heavy-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 ...
