Commuting by bicycle (vs. by car) is associated with improved aerobic power, microvascular function and diminished CO2 output in the atmosphere

Experimental Physiology, EarlyView.
Abstract The study investigated whether bicycle compared with car commuting, over relatively small distances, has positive effects on physiological variables, cardiometabolic fitness and CO2 output in the atmosphere. Bike Commuters (11 M, 15 F; age [median value (interquartile range)] 51.5 (38.3–56.8) years; body mass index [BMI] 22.8 (21.0–24.1) kg m ...

Evaluation of the two lightest quark masses

Ядерна фізика та енергетика, 2017
Simple relations between the masses of the two lightest up and down quarks were obtained on the basis of the simple physically based model compatible with the present-day theory of strong interactions, i.e. with quantum chromodynamics.

Analysis of excited quark propagator effects on neutron charge form factor

, 2019
The charge form factor and charge radius of neutron are investigated in the perturbative chiral quark model (PCQM) with considering both the ground and excited states in the quark propagator.

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

Experimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Search for production of vector-like quark pairs and of four top quarks in the lepton-plus-jets final state in $pp$ collisions at $\sqrt{s}=8$ TeV with the ATLAS detector [PDF]

, 2015
A search for pair production of vector-like quarks, both up-type (T ) and downtype (B), as well as for four-top-quark production, is presented. The search is based on pp collisions at √ s = 8TeV recorded in 2012 with the ATLAS detector at the CERN Large ...

Running economy and lower‐limb anthropometry in adult male Kenyan and Danish middle‐ and long‐distance runners and in untrained adolescents

Experimental Physiology, EarlyView.
Abstract Kenyan athletes have dominated competitive middle‐ and long‐distance running for more than half a century, a phenomenon suggested to be attributable, at least in part, to superior running economy. Given that lower‐leg anthropometry is an important determinant of running economy, a key contributor to the athletic performance of Kenyan runners ...

The global geometrical property of jet events in high-energy nuclear collisions

European Physical Journal C: Particles and Fields, 2020
We present the first theoretical study of medium modifications of the global geometrical pattern, i.e., transverse sphericity ( $$S_{\perp }$$ S ⊥ ) distribution of jet events with parton energy loss in relativistic heavy-ion collisions.

Machine learning of pair-contact process with diffusion

Scientific Reports, 2022
The pair-contact process with diffusion (PCPD), a generalized model of the ordinary pair-contact process (PCP) without diffusion, exhibits a continuous absorbing phase transition.

Non-perturbative structure of the polarized nucleon sea

, 2003
We investigate the flavour and quark-antiquark structure of the polarized nucleon by calculating the parton distribution functions of the nucleon sea using the meson cloud model. We find that the SU(2) flavor symmetry in the light antiquark sea and quark-

Constraining top quark effective theory in the LHC Run II era [PDF]

, 2015
A bstractWe perform an up-to-date global fit of top quark effective theory to experimental data from the Tevatron, and from LHC Runs I and II. Experimental data includes total cross-sections up to 13 TeV, as well as differential distributions, for both ...
