Article scientifique
Objectif. Dans la pratique de la clarinette, le pouce droit est en hyperextension, ce qui est une source fréquente de pathologie pour les clarinettistes. Nous avons évalué l’impact de la posture du musicien sur l’activité musculaire du court fléchisseur et du court extenseur afin de dégager la position limitant au maximum la sollicitation du pouce droit. Méthode. 26 clarinettistes amateurs ont ...
Head-neck rotational movements using DidRen laser test indicate children and seniors’ lower performance

- Article scientifique
Article scientifique
Sensorimotor control strategies during cervical axial rotation movements have been previously
explored in narrow age ranges but never concurrently in Children and Seniors
during a well-standardized task. However, the lifespan developmental approach provides
a framework for research in human sensorimotor control of the head-neck complex.
A cross-sectional design was used to investigate the influence ...
Unstable footwear as a speed-dependent noise-based training gear to exercise inverted pendulum motion during walking

- Article scientifique
Article scientifique
Previous research on unstable footwear has suggested that it may induce mechanical noise during
walking. The purpose of this study was to explore whether unstable footwear could be considered as a
noise-based training gear to exercise body center of mass (CoM) motion during walking. Ground
reaction forces were collected among 24 healthy young women walking at speeds between 3 and
6 km h−1 with ...
Clinical and MRI changes of puborectalis and iliococcygeus after a short period of intensive pelvic floor muscles training with or without instrumentation

Article scientifique
Purpose This study evaluates the impact of a 3-week period of intensive pelvic floor muscles training (PFMT), with or
without instrumentation, on clinical and static magnetic resonance imaging (MRI) changes of puborectalis (PR) and iliococcygeus
(IL) muscles.
Methods 24 healthy young women were enrolled in the study and 17 achieved the 9 sessions of 30 min training exercises
and conducted all ...
Relevance of glueball bound states in the Yang-Mills plasma within a many-body T-matrix approach
26 juillet 2012,
- HE Louvain en Hainaut
,
- Article scientifique
Article scientifique
The strongly coupled phase of Yang-Mills plasma with gauge group SU(3) is studied in a Tmatrix
approach. The existence of lowest-lying glueballs, interpreted as bound states of two
transverse gluons (quasi-particles in a many-body setup), is analyzed in a non-perturbative scattering
formalism with the input of lattice-QCD static potentials. The relevance of the singlet and
the (colored) octet ...
The SUSY Yang Mills plasma in a T-matrix approach
12 août 2015,
- HE Louvain en Hainaut
,
- Article scientifique
Article scientifique
In this paper, the thermodynamic properties of N = 1 supersymmetric Yang–Mills
theory with an arbitrary gauge group are investigated. In the confined range, we show
that identifying the bound state spectrum with a Hagedorn one coming from noncritical
closed superstring theory leads to a prediction for the value of the deconfining temperature
Tc that agrees with recent lattice data. The deconfined ...
Q-ball formation at the deconfinement temperature in large-Nc QCD
23 janvier 2013,
- HE Louvain en Hainaut
,
- Article scientifique
Article scientifique
The deconfinement phase transition in large-Nc QCD is studied within the framework of an effective
Polyakov-loop model, where the potential has a U(1) symmetry originating in the large-Nc limit of a
ZNc-symmetric model. At the critical temperature, the shape of the effective potential allows the existence
of Q-balls as position-dependent fluctuations of the Polyakov loop. Q-balls with spherical ...

Two- and three-body calculations within the dominantly orbital state method
14 mai 2013,
- HE Louvain en Hainaut
,
- Article scientifique
Article scientifique
The dominantly orbital state method allows a semiclassical description of quantum systems. At the origin, it was developed for two-body relativistic systems. Here, the method is extended to treat two-body Hamiltonians and systems with three identical particles, in D≥2 dimensions, with arbitrary kinetic energy and potential. This method is very easy to implement and can be used in a large variety of ...
Comments on Yang–Mills thermodynamics: The Hagedorn spectrum and the gluon gas pictures for a generic gauge algebra
20 octobre 2011,

,
- Article scientifique
Article scientifique
We discuss the dependence of pure Yang–Mills equation of state on the choice of gauge algebra. In the
confined phase, we generalize to an arbitrary simple gauge algebra Meyer’s proposal of modeling the
Yang–Mills matter by an ideal glueball gas in which the high-lying glueball spectrum is approximated by
a Hagedorn spectrum of closed-bosonic-string type. Such a formalism is undefined above the ...
