Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo, Dmitriy Garagash
Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compres- sive stress, propagating in a direction perpendicular to the latter. This class of tensile fractures has gained interest over the last fifty years due to the develo ...
2023Propagation of planar three-dimensional buoyant hydraulic fractures
Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compressive stress, propagating in a direction perpendicular to the latter. This class of tensile fractures has gained interest over the last fifty years due to the developm ...
EPFL2023Birth and ascent of buoyant hydraulic fractures
Brice Tanguy Alphonse Lecampion, Andreas Möri
Hydraulic fracturing treatments are often used in petroleum and other industries to increase the permeability of rock formations and occur naturally as magmatic intrusions. The resulting fractures, propagating perpendicularly to the minimum in-situ stress ...
2023Rapid motion estimation and correction using self-encoded FID navigators in 3D radial MRI
Purpose: To develop a self-navigated motion compensation strategy for 3D radial MRI that can compensate for continuous head motion by measuring rigid body motion parameters with high temporal resolution from the central k-space acquisition point (self-enco ...
Hoboken2023Young children can use their subjective straight-ahead to remap visuo-motor alterations
Jenifer Cléa Miehlbradt, Davide Esposito
Young children and adults process spatial information differently: the former use their bodies as primary reference, while adults seem capable of using abstract frames. The transition is estimated to occur between the 6th and the 12th year of age. The mech ...
NATURE PORTFOLIO2023Numerical and experimental investigation of spiral-grooved gas journal bearings
Small-scale turbomachinery is increasingly used in carbon-free energy conversion systems, such as commercial or domestic scale heat pumps, fuels cells for transportation and waste heat recovery. The usage of aerodynamic bearings allows the design of compac ...
EPFL2022Einstein-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 SOC2021Unstable tilting motion of flexibly supported gas bearing bushings
Jürg Alexander Schiffmann, Philipp Kaspar Bättig
This paper presents measurements of the motion amplitudes from flexibly supported Herringbone Grooved Journal Bearing bushings. Measurements taken in four locations on the flexibly supported bearing bushing enable the distinction between the radial and the ...
2021Secular effects of ultralight dark matter on binary pulsars
Sergey Sibiryakov, Diego Blas Temino
Dark matter (DM) can consist of very light bosons behaving as a classical scalar field that experiences coherent oscillations. The presence of this DM field would perturb the dynamics of celestial bodies, either because the (oscillating) DM stress tensor m ...
AMER PHYSICAL SOC2020Topology design of general tensegrity with rigid bodies
This study presents a general approach to the topology design of tensegrities with rigid bodies. To the best of the authors' knowledge, all existing topology design methods of tensegrities focus on tensegrities that only consist of members carrying axial f ...
