The generic Hidden Local Symmetry (HLS) model has given rise to the BHLS$_2$ variant which introduces symmetry breaking in the vector meson sector; the central mechanism is a modification of the covariant derivative at the root of the HLS approach. However, the description of the Belle $\tau$ dipion spectra is not satisfactory whereas the dealing w...

Developing advanced fracture tools can increase the understanding of crack growth trajectories in human cortical bone. The present study investigates fracture micromechanics of human cortical bone under compressive and tensile loadings utilizing a phase field method. We construct two-dimensional finite element models from cortical microstructure of...
The '$S_8$ tension' is a longstanding discrepancy between the cosmic microwave background (CMB) and weak gravitational lensing determination of the amplitude of matter fluctuations, parametrized as $S_8\equiv\sigma_8(\Omega_m/0.3)^{0.5}$, where $\sigma_8$ is the root mean square of matter fluctuations on a 8 $h^{-1}$Mpc scale, and $\Omega_m$ is the...
The study of lepton flavor universality violation (LFUV) in semitauonic $b$-hadron decays has become increasingly important in light of longstanding anomalies in their measured branching fractions, and the very large datasets anticipated from the LHC and Belle II. In this review, we undertake a comprehensive survey of the experimental environments ...
We reassess the viability of a cosmological model including a fourth additional sterile neutrino species that self-interacts through a new pseudoscalar degree of freedom. To that end, we perform a series of extensive analyses fitting various combinations of cosmic microwave background (CMB) data from Planck, the Atacama Cosmology Telescope (ACT) an...
Constitué de catégories descriptives spécifiques qui sont aptes, fondamentales à la saisie d'une perception, le signe relève de la jonction entre deux axes : (i) l'axe de la structuration du monde de l'expression sémiotique et (ii) l'axe de l'extension maximale du signe vers la perception, l'esthésie et toutes les dimensions phénoménologiques de l'...

AbstractAll types of plastic deformation, such as tension–compression, bending, and torsion, are implemented during cold metal forming. Each type of deformation results in specific hardening patterns. Cyclic deformation causes hardening–softening processes and residual stresses (RSs). RSs form due to reversible dislocation movement. A new dislocati...

AbstractTension and bending tests of commercially pure VT1-0 and Grade 4 titanium were carried out to assess the influence of the electroplastic effect on the strength and deformability. The optimal modes and states of a current for bending of medical implant blanks have been determined. It has been shown that the electroplastic effect makes it pos...

AbstractThe use of a magnetorheological elastomer (a polymer) in an active vibration isolation system is considered. The best combination and concentrations of such elastomers are determined for vibration isolation systems operating in vacuum.
Mammalian cells integrate different types of stimuli that govern their fate. These stimuli encompass biochemical as well as biomechanical cues (shear, tensile, and compressive stresses) that are usually studied separately. The phosphatidylinositol 3-kinase (PI3K) enzymes, producing signaling phosphoinositides at plasma and intracellular membranes, ...
