Alexandre Koyré and the traditional interpretation of the anthropological consequences of the Copernican Revolution

Article scientifique
L’œuvre d’Alexandre Koyré prenant place, chronologiquement, entre la fin de la phase de structuration définitive (1925) de l’interprétation traditionnelle de la révolution copernicienne et l’apparition de ses premières remises en question les plus abouties (1969), il nous a semblé opportun d’examiner jusqu’à quel point cette œuvre souscrit à cette interprétation ou, au contraire, prépare sa remise ...
Pierre Duhem’s philosophy and history of science

Livre/Ouvrage ou monographie
We are pleased to present in this issue a tribute to the thought of Pierre Duhem, on the occasion of the centenary of his death that occurred in 2016. Among articles and book reviews, the dossier contains 14 contributions of scholars from different places across the world, from Europe (Belgium, Greece, Italy, Portugal and Sweden) to the Americas (Brazil, Canada, Mexico and the United States). And ...
Learning the Physics of Einstein with Georges Lemaître : Before the Big Bang Theory

- Livre/Ouvrage ou monographie
Livre/Ouvrage ou monographie
This book presents the first English translation of the original French treatise “La Physique d’Einstein” written by the young Georges Lemaître in 1922, only six years after the publication of Albert Einstein’s theory of General Relativity. It includes an historical introduction and a critical edition of the original treatise in French supplemented by the author’s own later additions and ...
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
15 mai 2018,

,
- 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 ...
Benefits of nonlinear analysis indices of walking stride interval in the evaluation of neurodegenerative diseases
12 décembre 2020,

,
- Article scientifique
Article scientifique
Indices characterising the long-range temporal structure of walking stride interval (SI) variability such as Hurst exponent (H) and fractal dimension (D) may be used in addition to indices measuring the amount of variability like the coefficient of variation (CV). We assess the added value of the former indices in a clinical neurological context. Our aim is to demonstrate that they provide a clinical ...
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 ...
