Acute and lifelong exercise modulate the tumorigenic potential of human lung cancer cells and their susceptibility to cisplatin

open access: yesExperimental Physiology, EarlyView.
Abstract The association between higher levels of physical activity and lower cancer risk and mortality is well established. However, a causal link is yet to be proven. Recent studies showed a decrease in the proliferation rates of cultured human cancer cells when the human serum used to stimulate them was conditioned by acute exercise. Here, we tested

Measurement of the top quark pair production cross section in pp collisions at √s=7  TeV in dilepton final states with ATLAS [PDF]

open access: yes, 2011
A measurement of the production cross section of top quark pairs (t<span style="text-decoration: overline">t</span>) in proton–proton collisions at a center-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron Collider

Does nuclear medium affect the transverse momentum-dependent parton distributions of valence quark of pions?

open access: yesPhysics Letters B
We calculate the valence quark transverse momentum-dependent parton distributions (TMDs) of the lightest pseudoscalar meson, pions, in isospin asymmetric nuclear matter at zero temperature by employing a light-cone quark model.

Effect of an acute exercise bout on alveolar–capillary membrane permeability and interstitial fluid accumulation in COPD

open access: yesExperimental Physiology, EarlyView.
Abstract Exertional dyspnoea is a debilitating symptom in chronic obstructive pulmonary disease (COPD) and often persists after the cessation of exercise. The underlying mechanisms are not fully understood, and a potential contributing factor that has not previously been investigated is alveolar–capillary membrane breaching with extravasation of fluid ...

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 ...

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 ...

Radioactivity of quark nuggets

open access: yesJournal of High Energy Physics
Quark nuggets Q Z A $$ {}_{\textrm{Z}}{}^{\textrm{A}}\textrm{Q} $$ , as Fermionic non-topological solitons, could have their mass per baryon smaller than ordinary nuclei and behave as exotic nuclei with different relations of atomic number and atomic ...

Finite modular subgroups for fermion mass matrices and baryon/lepton number violation

open access: yesPhysics Letters B, 2019
We study a flavor model that the quark sector has the S3 modular symmetry while the lepton sector has the A4 modular symmetry. Our model leads to characteristic quark mass matrices which are consistent with experimental data of quark masses, mixing ...

Polynomial Preconditioning for Indefinite Matrices

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT Polynomial preconditioning is an important tool in solving large linear systems and eigenvalue problems. A polynomial from GMRES can be used to precondition restarted GMRES and restarted Arnoldi. Here we give methods for indefinite matrices that make polynomial preconditioning more generally applicable. The new techniques include balancing the
