Novel screening with two bodies: summing the ladder in disformal scalar-tensor theories

“…(2.25), with M 4 ∼ Λ 3 3 M P ), we instead imagine that heavy fields have been integrated out directly at the scale M, where the only symmetry is an approximate shift symmetry for φ. In an upcoming work [64], we demonstrate that this choice is also consistent with the physics in the Jordanframe: a field redefinition of a purely disformal coupling in the Einstein-frame (which lives at M) into the Jordan-frame results in a special Horndeski theory (which enjoys a cancellation of every operator below M) that does not exhibit conventional Vainshtein screening at R V .…”

“…For instance, it does not seem to occur for single bodies, is absent if both particles are at rest, and is controlled by the geometric mean √ m 1 m 2 of the masses. We will show explicitly in an upcoming work [64] that an explicit field redefinition of the simple model (1.2) to the Jordan-frame results in a particular Horndeski theory (namely the quartic DBI Galileon [65,66]) in which the gravitational mixing exactly cancels the Galileon-type operators which are usually responsible for Vainshtein. Consequently, this ladder screening appears to be independent of the Vainshtein mechanism.…”

Correlación entre espacios de características acústicas del habla y trastornos clínicos de la voz en pacientes con disfagia

“…En términos de estas características, las vocales \a\, \i\ y \u\ representan los movimientos articulatorios extremos, por lo que reciben el nombre de "vocales de las esquinas del triángulo vocal", estudiadas en [31], [32], [33]. En cuanto al dominio cepstral en el análisis de las vocales sostenidas, se calcularon los coeficientes cepstrales de frecuencia de Mel (MFCC, por sus siglas en inglés), que se pueden entender como la representación del habla que se basa en la percepción auditiva humana [34].…”
