Estudio de diferentes parámetros para la detección de esclerosis lateral amiotrófica a partir del movimiento articulatorio

Amyotrophic lateral sclerosis (ALS) is a degenerative neuromuscular disease, one of its early symptoms being a progressive difficulty to speak (ALS dysarthria). To improve its diagnosis and monitoring, a new method based on articulatory movement estimation has been developed. As a result, two articulatory movement parameters are presented as well as their relationship with the illness grade.La esclerosis lateral amiotrófica (ELA) es una enfermedad degenerativa de tipo neuromuscular, uno de cuyos primeros síntomas es la dificultad para hablar. Recientemente se ha presentado un nuevo método para determinar el movimiento articulatorio a partir de la estimación de los formantes. En este artículo se presentan dos parámetros obtenidos mediante el modelado del movimiento articulatorio y se evalúan con respecto al grado de la enfermedad

What does the central limit theorem have to say about general relativity?

ABSTRACT: In this paper, we speculate on a possible connection between the Bayes’s law and the Einstein’s general relativity equation to support the use of a metric based on an erfc gravitational potential that has been recently proposed to provide some cues to open problems in the solar systems. Starting from a basic interdependence premise, an analogy between Einstein’s equation and Bayes’s law is used to analyze the linear case of a weak field static symmetric massive object, providing a probabilistic context that takes into account the probability of presence of a given energy density in its corresponding 4D curved space-time manifold. Using the Central Limit Theorem to model globally the very slow process of star formation and mathematically express the corresponding probability density, the new framework provides a rationale for the emergence of a weighted Newton’s law of gravitation. One key feature of this modified gravity model is that it relies on the existence of an intrinsic emergent physical constant σ, a star-specific proper length that scales all its surroundings

Drawing, Handwriting Processing Analysis: New Advances and Challenges

International audienceDrawing and handwriting are communicational skills that are fundamental in geopolitical, ideological and technological evolutions of all time. drawingand handwriting are still useful in defining innovative applications in numerous fields. In this regard, researchers have to solve new problems like those related to the manner in which drawing and handwriting become an efficient way to command various connected objects; or to validate graphomotor skills as evident and objective sources of data useful in the study of human beings, their capabilities and their limits from birth to decline
