      Voluntary human movements are stereotyped. When modeled in the framework of classical mechanics they are expected to minimize cost functions that may include energy, a natural candidate from a physiological point of view also. In time-changing environments, however, energy is no longer conserved—regardless of frictional energy dissipation—and it is therefore not the preferred candidate for any cost ...

    • Anyons in quantum mechanics with a minimal lengthPeer reviewedOpen access 

      15 février 2017, BUISSERET, Fabien, HE Louvain en Hainaut
      Article scientifique
      The existence of anyons, i.e. quantum states with an arbitrary spin, is a generic feature of standard quantum mechanics in (2+1)-dimensional Minkowski spacetime. Here it is shown that relativistic anyons may exist also in quantum theories where a minimal length is present. The interplay between minimal length and arbitrary spin effects are discussed.

      Comme tous les systèmes dynamiques, l’Homme est soumis aux lois de la mécanique. Il n’est toutefois pas réductible à une machine comme les autres : il est biologique, psychologique et social ! La douleur, définie comme une expérience sensorielle et émotionnelle désagréable associée à une lésion tissulaire réelle ou non, est une composante de nature complexe. Elle se manifeste notamment dans les ...
    • Cinématique du grand battement et du développé chez des danseurs amateurs : effets à court terme d’un étirement statique ou dynamiquePeer reviewedOpen access

      Article scientifique
      Les jeunes danseurs amateurs semblent utiliser majoritairement l’étirement statique. Or, la littérature montre également l’efficacité de l’étirement dynamique sur la performance des sportifs. L’un de ces étirements est-il dès lors plus favorable à l’exécution de deux mouvements de danse classique, le grand battement et développé ? Seize participants ont réalisé ces mouvements dans trois conditions ...

      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 ...

    • Diffusion in Phase Space as a Tool to Assess Variability of Vertical Centre-of-Mass Motion during Long-Range WalkingPeer reviewedOpen access

      Article scientifique
      When a Hamiltonian system undergoes a stochastic, time-dependent anharmonic perturbation, the values of its adiabatic invariants as a function of time follow a distribution whose shape obeys a Fokker–Planck equation. The effective dynamics of the body’s centre-of-mass during human walking is expected to represent such a stochastically perturbed dynamical system. By studying, in phase space, the ...

      Various noninvasive measurement devices can be used to assess cervical motion. The size, complexity, and cost of gold-standard systems make them not suited to clinical practice, and actually difficult to use outside a dedicated laboratory. Nowadays, ultra-low-cost inertial measurement units are available, but without any packaging or a user-friendly interface. The so-called DYSKIMOT is a home-designed, ...

      Article scientifique
      We first quantize an action proposed by Casalbuoni and Gomis in 2014 that describes two massless relativistic scalar particles interacting via a conformally invariant potential. The spectrum is a continuum of massive states that may be interpreted as unparticles. We then obtain in a similar way the mass operator for a deformed action in which two terms are introduced that break the conformal symmetry: ...

      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. ...

      The equation of state of SU(3) Yang–Mills theory can be modelled by an effective Z3− symmetric potential depending on the temperature and on a complex scalar field ϕ . Allowing ϕ to be dynamical opens the way to the study of spatially localized classical configurations of the scalar field. We first show that spherically symmetric static Q-balls exist in the range (1−1.21)×Tc , Tc being the ...
