Boson stars and black holes with complex and real scalar hair
08 avril 2025, CeREF TechniqueArticle scientifiqueWe discuss boson stars and black holes with scalar hair in a model where the complex scalar field forming the boson star and the hair on the black hole, respectively, interacts with a real scalar field via a H´enon-Heiles-type potential. We demonstrate that black holes and boson stars carrying only a real scalar field with cubic self-interaction are possible and that black holes with both real ... -
Evaluating cervical spine mobility and Fitt’s law compliance: The DidRen laser test adapted for virtual reality with age and sex effects
28 août 2024, CeREF SantéCeREF TechniqueArticle scientifiqueCervical spine mobility assessment is crucial in rehabilitation to monitor patient progress. This study introduces the DidRen VR test, a virtual reality (VR) adaptation of the conventional DidRen laser test, aimed at evaluating cervical spine mobility. We conducted a cross-sectional study involving fifty healthy participants that underwent the DidRen VR test. The satisfaction of Fitts’ law within ... -
Q-balls and charged Q-balls in a two-scalar field theory with generalized Henon-Heiles potential
30 avril 2024, CeREF TechniqueArticle scientifiqueWe construct Q-ball solutions from a model consisting of one massive scalar field ξ and one massive complex scalar field ϕ interacting via the cubic couplings g1ξϕ ϕ þ g2ξ3, typical of Henon-Heiles-like potentials. Although being formally simple, these couplings allow for Q-balls. In one spatial dimension, analytical solutions exist, either with vanishing or nonvanishing ϕ. In three spatial ... -

Evaluating the additive diagnostic value of DidRen LaserTest: Correlating temporal and kinematic predictors and patient-reported outcome measures in acute-subacute non-specific neck pain
12 mars 2024, CeREF SantéArticle scientifiqueThis study aims to investigate the relationships between altered kinematic parameters, as assessed by the DidRen laser test, and PROMs. Using a multivariate logistic regression (LR) model, we sought to identify the best predictors for discriminating ANSP patients from HCP. We hypothesized that the DidRen laser test would reveal different relationships between kinematic parameters and PROMs ... -
Hamilton, Lagrange, le chaos. Cette Mécanique dans nos mouvements.
20 février 2024, CeREF SantéAutreLa compréhension des principes fondamentaux régissant les mouvements observés dans la Nature est un objectif fondamental de la science. Après les travaux pionniers de Newton (1643-1727), la Mécanique a considérablement évolué grâce aux reformulations de Lagrange (1736-1813) et de Hamilton (1805-1865). En invoquant un principe de moindre action, Lagrange a remplacé l'équation de Newton par la recherche ... -
Occupational Risk Factors for Musculoskeletal Disorders among Workers in Dairy Diversification
11 janvier 2024, CeREF SantéArticle scientifiqueAbstract Background: In a changing European agricultural context, diversification of dairy farms is gaining attention. This study seeks to (1) assess musculoskeletal pain prevalence associated with tasks such as butter, yogurt, and cheese production; and (2) analyze associated risks. Methods: Observing 31, mostly female, workers, we utilized the ERGOROM questionnaire, a methodology adapted from ... -

Intégrer le numérique dans la discipline du français : exemples raisonnés de pratiques enseignantes
10 mai 2023, CeREF EducationArticle scientifiqueAu XXIe siècle, le numérique tient une place importante dans l’enseignement. En Belgique francophone, une plateforme de ressources didactiques accompagne les enseignants dans le développement des compétences numériques en littératie. Nous examinons la place laissée à la littérature numérique sur cette plateforme et les ressources qu’elle propose. Enfin, nous décrivons comment ces dernières pourraient ... -
Diffusion in Phase Space as a Tool to Assess Variability of Vertical Centre-of-Mass Motion during Long-Range Walking
06 février 2023, CeREF SantéCeREF TechniqueArticle scientifiqueWhen 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 ... -
Quasi‑experimental pilot study to improve mobility and balance in recurrently falling nursing home residents by voluntary non‑targeted side‑stepping exercise intervention
30 décembre 2022, HE Louvain en HainautArticle scientifiqueBackground: 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 ... -
A Persistent Myth: Comparing Geocentrism to Anthropocentrism and how this Vain Illusion Was Shattered by Heliocentrism — Demonstrating the Importance of Scientific Historiography by Way of a Discussion between a Student and one of His Professors
Article scientifiqueAccording to the Copernican myth, geocentrism was a form of anthropocentrism because it showcased humankind as being both the centre and the purpose of the Cosmos, whereas heliocentrism, in dethroning humankind from this privileged position, luckily provided a means to quash this point of view, which was illusory and vain, and that even went against scientific progress. According to the anthropocentric ... -
