A Study on the Dynamic Behaviour of Lightweight Gears by Shadi Shweiki, Antonio Palermo, Domenico Mundo

“…High computational efficiency is reached by using a spring-damper element with variable stiffness to model the gear meshing process. The angle-dependent mesh stiffness function is computed in a preparation phase through detailed Finite Element (FE) simulations and then stored in a lookup table, which is then interpolated during the dynamic simulation allowing for high computational efficiency. …”

Mocking Andromeda in Julia Constance Fletcher’s The Fantasticks (1900) by Rebecca Nesvet

“…The early 2000s, Catherine Delyfer observes, saw unprecedented scholarly interest in the fin-de-siècle’s ‘more conflicted women artists, essayists, poets, and novelists, whose works often broach New Woman themes but from an aloof, highly literary angle, foregrounding aesthetic issues and complex gendered perspectives’ (Delyfer 14). …”

Phenomenology of keV scale sterile neutrino dark matter with S4 flavor symmetry by Nayana Gautam, Mrinal Kumar Das

“…The structures of the mass matrices involved in inverse seesaw within the S4 framework naturally give rise to correct neutrino mass matrix with non-zero reactor mixing angle θ13. In this framework, we conduct a detailed numerical analysis both for normal hierarchy as well as inverted hierarchy to obtain dark matter mass and DM-active mixing which are the key factors for considering sterile neutrino as a viable dark matter candidate. …”

Extracting Kinetic Freeze-Out Properties in High-Energy Collisions Using a Multisource Thermal Model by Jia-Yu Chen, Mai-Ying Duan, Fu-Hu Liu, Khusniddin K. Olimov

“…It is assumed that the contribution to the pT-value of any hadron comes from two or three partons with an isotropic distribution of the azimuthal angle. The contribution of each parton to the pT-value of a given hadron is assumed to obey any one of the standard (Maxwell-Boltzmann, Fermi-Dirac, and Bose-Einstein) distributions with the kinetic freeze-out temperature and average transverse flow velocity. …”
