Liquid film instability of an internally coated horizontal tube
François Gallaire, Edouard Boujo, Yves-Marie François Ducimetière, Shahab Eghbali
We study numerically and theoretically the gravity-driven flow of a viscous liquid film coating the inner side of a horizontal cylindrical tube and surrounding a shear-free dynamically inert gaseous core. The liquid-gas interface is prone to the Rayleigh-P ...
AMER PHYSICAL SOC2023Experimental and numerical investigation of the unbalance behavior of rigid rotors supported by spiral-grooved gas journal bearings
Jürg Alexander Schiffmann, Elia Iseli
The forced response of rigid rotors, supported by herringbone-grooved gas journal bearings are investigated numerically and experimentally. The rotor configurations are varied by using end cylinders, attached at both sides of the shaft. Three rotors with d ...
ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD2022Locally active globally stable dynamical systems: Theory, learning, and experiments
Aude Billard, Nadia Barbara Figueroa Fernandez
State-dependent dynamical systems (DSs) offer adaptivity, reactivity, and robustness to perturbations in motion planning and physical human-robot interaction tasks. Learning DS-based motion plans from non-linear reference trajectories is an active research ...
SAGE PUBLICATIONS LTD2022Einstein-Cartan Portal to Dark Matter
Andrey Shkerin, Inar Timiryasov, Sebastian Zell
It is well known since the works of Utiyama and Kibble that the gravitational force can be obtained by gauging the Poincare group, which puts gravity on the same footing as the standard model fields. The resulting theory-Einstein-Cartan gravity-inevitably ...
AMER PHYSICAL SOC2021Quasi-stationary flow structure in turbidity currents
Giovanni De Cesare, Shun Nomura
A turbidity current is a particle-laden current driven by density differences due to suspended sediment particles. Turbidity currents can transport large amounts of sediment down slopes over great distances, and play a significant role in fluvial, lake and ...
IRTCES2020Gravitational Mass Carried by Sound Waves
We show that the commonly accepted statement that sound waves do not transport mass is only true at linear order. Using effective field theory techniques, we confirm the result found by Nicolis and Penco [Phys. Rev. 13 97, 134516 (2018)] for zero -temperat ...
AMER PHYSICAL SOC2019Towards the renormalization group flow of Horava gravity in 3+1 dimensions
Sergey Sibiryakov, Mario Herrero Valea
We compute the renormalization group running of the Newton constant and the parameter lambda in (3 + 1)-dimensional projectable Horava gravity. We use the background-field method, expanding around configurations with flat spatial metric, but nonvanishing s ...

Gait recovery after neurological disorders requires remastering the interplay between body mechanics and gravitational forces. Despite the importance of gravity-dependent gait interactions and active participation for promoting this learning, these essenti ...
Amer Assoc Advancement Science2017Stokes' third problem for Herschel-Bulkley fluids.
Christophe Ancey, Belinda Margaret Bates
Herschel-Bulkley materials can be set in motion when a sufficiently high shear stress or body force is applied to them. We investigate the behaviour of a layer of Herschel-Bulkley fluid when it is suddenly tilted and subject to gravitational forces. The ma ...
Elsevier2017Looking for dark matter trails in colliding galaxy clusters
Jean-Paul Richard Kneib, David Richard Harvey, Richard Massey
If dark matter interacts, even weakly, via non-gravitational forces, simulations predict that it will be preferentially scattered towards the trailing edge of the halo during collisions between galaxy clusters. This will temporarily create a non-symmetric ...
