CP violation of quarks in A4 modular invariance

Physics Letters B, 2019
We discuss the quark mass matrices in the A4 modular symmetry, where the A4 triplet of Higgs is introduced for each up-quark and down-quark sectors, respectively.

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

Experimental Physiology, Volume 111, Issue 4, Page 1919-1932, 1 April 2026.
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 ...

Equation of state of quark-gluon plasma using a simple phenomenological model

EPJ Web of Conferences, 2018
The equation of state (EoS) of quark-gluon plasma (QGP) using a phenomenological model is studied in which finite value of quark mass is modified as effective mass.

Testing for three-body quark forces in L=1 excited baryons

, 2010
We discuss the matching of the quark model to the effective mass operator of the 1/Nc expansion using the permutation group S_N. As an illustration of the general procedure we perform the matching of the Isgur-Karl model for the spectrum of the negative ...

Sex and performance‐level differences in aerobic and haematological parameters among elite ski mountaineering athletes

Experimental Physiology, Volume 111, Issue 4, Page 1988-2001, 1 April 2026.
Abstract Ski mountaineering (SkiMo) is a new Olympic sport with extreme endurance demands and altitude exposure. Previous studies have focused on traditional cardiorespiratory variables, such as maximal oxygen consumption (V̇O2max${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$) or ventilatory thresholds, but, to our knowledge, did not report ...

Flavor-changing phenomenology in a U(1) model

European Physical Journal C: Particles and Fields
We study family-nonuniversal extensions of the SM, based upon gauge symmetry $$SU(3)_C \otimes SU(2)_L \otimes U(1)_X \otimes U(1)_N$$ S U ( 3 ) C ⊗ S U ( 2 ) L ⊗ U ( 1 ) X ⊗ U ( 1 ) N , where the last two factors determine the hypercharge, $$Y=X+N$$ Y =

Exotic hadrons from dynamical clustering of quarks in ultrarelativistic heavy ion collisions

, 2004
Results from a model study on the formation of exotic quark clusters at the hadronization stage of a heavy ion collision are presented. The dynamical quark molecular dynamics (qMD) model which is used is sketched, and results for exotica made of up to ...

Effect of hypoxia on muscle activation at equivalent absolute and relative intensity during incremental and constant load exercise to task failure

Experimental Physiology, Volume 111, Issue 4, Page 1933-1947, 1 April 2026.
Abstract We examined the impact of moderate hypoxia (HYPO) on muscle activation during incremental exercise matched for both absolute and equivalent relative intensity. Fifteen active subjects (10 males, 5 females) completed two ramp incremental test and two step tests in normoxia (NORM; FiO2${F_{{\mathrm{i}}{{\mathrm{O}}_2}}}$ = 0.209) and HYPO (FiO2${

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

The 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.
