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

open access: yesThe 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 ...

PROPERTIES OF MAGNETIZED QUARK-HYBRID STARS [PDF]

open access: yesInternational Journal of Modern Physics E, 2011
The structure of a magnetized quark-hybrid stars (QHS) is modeled using a standard relativistic mean-field equation of state (EoS) for the description of hadronic matter. For quark matter we consider a bag model EoS which is modified perturbatively to account for the presence of a uniform magnetic field.

Proto-strange quark stars from density-dependent quark mass model

open access: yesEuropean Physical Journal C: Particles and Fields
In this paper, we investigate the evolution of strange quark stars (SQS) from birth as proto-strange quark stars to maturity as stable SQSs at a zero temperature.

Hot Holographic 2-Flavor Quark Star

open access: yesUniverse
Applying the holographic 2-flavor Einstein–Maxwell-dilaton model, the parameters of which are fixed by lattice QCD, we extract the equations of state for hot quark–gluon plasma around the critical point at T=182 MeV, and have corresponding quark star ...

1-2-3-flavor color superconductivity in compact stars

open access: yes, 2008
We suggest a scenario where the three light quark flavors are sequentially deconfined under increasing pressure in cold asymmetric nuclear matter, e.g., as in neutron stars. The basis for our analysis is a chiral quark matter model of Nambu--Jona-Lasinio

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

open access: yesThe 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 ...

Hybrid stars that masquerade as neutron stars

open access: yes, 2004
We show that a hybrid (nuclear + quark matter) star can have a mass-radius relationship very similar to that predicted for a star made of purely nucleonic matter. We show this for a generic parameterization of the quark matter equation of state, and also

Solo Versus Tandem Cycling Performance: The Whole Is Less Than the Sum of the Parts

open access: yesEuropean Journal of Sport Science, Volume 25, Issue 9, September 2025.
ABSTRACT Tandem cycling is a Paralympic discipline where two cyclists share one bicycle and requires synchronization and shared effort. In this study, we investigated how individual performance on a solo bicycle compares to tandem cycling. Twelve trained cyclists, that were unfamiliar with tandem cycling, completed a submaximal cycling test, a 30 s ...

Investigating the Modulation of Corticomotor and Neuromuscular Function by Contralateral and Ipsilateral Experimental Pain Applied During Cycling

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 35, Issue 9, September 2025.
ABSTRACT Pain can impair exercise performance, but its influence on motor control, in particular the effect of robust experimental pain on the timecourse of corticomotor responses throughout prolonged, exhaustive cycling, remains unclear. We tested the hypothesis that an augmented experimental pain intervention applied to exercising and non‐exercising ...
