HEAVY QUARK PHYSICS FROM LATTICE QCD [PDF]

open access: yes, 1998
We review the application of lattice QCD to the phenomenology of b- and c-quarks. After a short discussion of the lattice techniques used to evaluate hadronic matrix elements and the corresponding systematic uncertainties, we summarise results for leptonic decay constants, B--Bbar mixing, semileptonic and rare radiative decays.

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

open access: yesThe Journal of Physiology, Volume 604, Issue 7, Page 3175-3200, 1 April 2026.
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.

Neural network modeling of heavy-quark potential from holography

open access: yesEuropean Physical Journal C: Particles and Fields
Using Multi-Layer Perceptrons (MLP) and Kolmogorov–Arnold Networks (KAN), we construct a holographic model based on lattice QCD data for the heavy-quark potential in the 2+1 system.

Metabolic, V̇O2 kinetics, and muscle oxygenation responses at and above maximal lactate steady state in trained male rowers

open access: yesPhysiological Reports, Volume 14, Issue 8, April 2026.
Abstract This study aimed to compare physiological responses during rowing ergometer exercise at the maximal lactate steady state (MLSS) and 5% above the MLSS (MLSS+5%). Blood lactate concentration (BLC), oxygen uptake (V̇O2) kinetics, heart rate (HR), and muscle oxygenation (deoxygenated hemoglobin [HHb] and tissue saturation index [TSI]) of the ...

Non‐Invasive Estimation of the Upper Boundary of the Severe Intensity Exercise Domain: The Maximal Accumulated Oxygen Deficit Method

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 3, March 2026.
ABSTRACT The aim of this study was to evaluate whether the highest power output at which the predominant energy contribution is derived from the aerobic system (aerobic limit power: ALP), as estimated using maximal accumulated O2 deficit (MAOD) method, corresponds to the upper boundary of the severe intensity exercise domain. Thirteen males completed: (

Coulomb artifacts and breakdown of perturbative matching in lattice NRQCD

open access: yesJournal of High Energy Physics, 2017
By studying an explicit analytical solution of the Schrödinger equation with the Coulomb potential on the lattice we demonstrate a breakdown of perturbative matching for the description of the Coulomb artifacts in lattice NRQCD, which leads to a large ...

Food Apartheid on the Virginia Peninsula: Serial Forced Displacement Meets Serial Environmental Racism

open access: yesAntipode, Volume 58, Issue 2, March 2026.
ABSTRACT Since 2013, the state of Virginia has pursued two significant initiatives: a commemoration of the forcible arrival of Africans in 1619 and a state‐level council to address food deserts. Yet, there has been little discussion of their interconnections. We ask what role might this 400‐year history play in the existence of food deserts today?

A method for model-independent measurement of the CKM angle β via time-dependent analysis of the B 0 → Dπ + π −, D → K s 0 π + π − decays

open access: yesJournal of High Energy Physics, 2018
A new method for model-independent measurement of the CKM angle β is proposed, that employs time-dependent analysis of flavour-tagged B 0 → Dπ+π− decays with D meson decays into C P $$ \mathcal{C}\mathcal{P} $$ -specific and K s 0 π + π − final states ...

Acute Hypoxia Decreases Maximum Fat Oxidation Rate During Step Incremental Exercise Normalized to Respiratory Compensation Point

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 2, February 2026.
ABSTRACT Whether fat oxidation (FATox) is altered during exercise in hypoxia remains equivocal due to differences in experimental protocols. Furthermore, to date no investigation has reported the effect of hypoxia on maximal fat oxidation rate (MFO).
