ZN-balls: Solitons from ZN-symmetric scalar field theory
Article scientifique
We discuss the conditions under which static, finite-energy, configurations of a complex scalar field ϕ
with constant phase and spherically-symmetric norm exist in a potential of the form V(ϕ*ϕ, ϕ^N, ϕ^*N)
with N ∈ N and N ≥ 2, i.e., a potential with a ZN-symmetry. Such configurations are called ZN-balls. We
build explicit solutions in (3 + 1)-dimensions from a model mimicking effective field ...

Recent advances in electronics have led to sensors whose sizes and weights are such that they can be placed on living systems without impairing their natural motion and habits. They may be worn on the body as accessories or as part of the clothing and enable personalized mobile information processing. Wearable sensors open the way for a nonintrusive and continuous monitoring of body orientation, ...

Introduction: The variability of human walking has been studied for about twenty years. It appears not
to be random but long-term autocorrelated, i.e. on time scales corresponding to several hundreds of gait
cycles. It has been shown that the central nervous system (CNS) plays an important role in this
variability. Indeed, people with CNS alterations have a different autocorrelation pattern than ...

The aim of this study was to carry out a kinematic analysis of the lower limb during gait in subjects with
asymptomatic genu recurvatum. The sagittal plane kinematics of the lower limb during gait in a group
of 13 subjects with genu recurvatum was shown to be significantly different to that of a group of 13
control healthy subjects. An increase in extension and a decrease in flexion of the hip ...
Unstable footwear as a speed-dependent noise-based training gear to exercise inverted pendulum motion during walking

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 ...
Two- and three-body calculations within the dominantly orbital state method
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 ...
Timed Up and Go and Six-Minute Walking Tests with Wearable Inertial Sensor: One Step Further for the Prediction of the Risk of Fall in Elderly Nursing Home People

Assessing the risk of fall in elderly people is a difficult challenge for clinicians. Since falls represent one of the first causes of death in such people, numerous clinical tests have been created and validated over the past 30 years to ascertain the risk of falls. More recently, the developments of low-cost motion capture sensors have facilitated observations of gait differences between fallers ...
Thermodynamics of the quark-gluon plasma within a T-matrix approach

- Article scientifique
Article scientifique
The strongly coupled phase of the quark-gluon plasma (QGP) is studied here by resorting to a T -matrix
formulation in which the medium is seen as a nonideal gas of quasiparticles (quarks, antiquarks, and gluons)
interacting nonpertubatively. In the temperature range under study, (1–5)Tc, where Tc is the temperature of
deconfinement, the interactions are expected to be strong enough to generate ...

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 ...
The Formulations of Classical Mechanics with Foucault’s Pendulum
Article scientifique
Since the pioneering works of Newton (1643–1727), Mechanics has been constantly reinventing itself: reformulated in particular by Lagrange (1736–1813) then Hamilton (1805–1865), it now offers powerful conceptual and mathematical tools for the exploration of dynamical systems, essentially via the action-angle variables formulation and more generally through the theory of canonical transformations. ...

L’évaluation du risque de chute chez les personnes âgées est un véritable défi pour les thérapeutes, les chutes constituant en effet une des premières causes de mortalité chez cette population. De nombreux tests cliniques ont été développés et validés durant les 30 dernières années. Plus récemment, l’émergence de capteurs de mouvement à faible coût facilite l’observation des différences cinématiques ...

Sample Entropy as a Tool to Assess Lumbo-Pelvic Movements in a Clinical Test for Low-Back-Pain Patients

Article scientifique
Low back pain (LBP) obviously reduces the quality of life but is also the world’s leading
cause of years lived with disability. Alterations in motor response and changes in movement patterns
are expected in LBP patients when compared to healthy people. Such changes in dynamics may be
assessed by the nonlinear analysis of kinematical time series recorded from one patient’s motion.
Since sample ...
Relevance of glueball bound states in the Yang-Mills plasma within a many-body T-matrix approach

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 ...

Background: Side-stepping is a potential exercise program to reduce fall risk in community-dwelling adults in their
seventies, but it has never been tested in nursing home residents. This was a pilot quasi-experimental study to examine
the feasibility and potential mobility and balance benefits of an intervention based on voluntary non-targeted
side-stepping exercises in nursing home residents ...
Q-ball formation at the deconfinement temperature in large-Nc QCD
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 ...
