Active axial stress in mouse aorta

Nikolaos Stergiopoulos, Aristotelis Agianniotis, Alexander Rachev

The study verifies the development of active axial stress in the wall of mouse aorta over a range of physiological loads when the smooth muscle cells are stimulated to contract. The results obtained show that the active axial stress is virtually independen ...

Dynamics of Slip Fronts at Frictional Interfaces: Analysis of Slip Precursors and Rupture Velocity

Jean-François Molinari, Mathilde Edmée Lucette Radiguet de la Bastaie, David Simon Kammer, Vladislav Yastrebov

The rupture dynamics of earthquakes span a considerable range, from slow to super-shear ruptures. Rupture speed has a major influence on the generation of strong ground motions, yet our understanding of the mechanisms causing these variations in the ruptur ...

Opto-acoustic coupling and Brillouin phenomena in microstructure optical fibers

Luc Thévenaz, Stella Foaleng Mafang, Duc Minh Nguyen

Like photonic crystals have revolutionized the way of manipulating optical waves at the sub-micron scale, phononic crystals have more recently played similar decisive role for sound waves, or more generally elastic waves. Then, the idea of coupling light a ...

Enhanced Transmission through Squeezed Modes in a Self-Cladding Magnonic Waveguide

Dirk Grundler

We study spin-wave propagation in 360-nm wide Ni80Fe20 nanowires using all-electrical spin-wave spectroscopy. Creating a zigzag-like magnetization state, we find enhanced spin-wave transmission compared to the states of more homogeneous magnetization. Micr ...

Mode conversion from quantized to propagating spin waves in a rhombic antidot lattice supporting spin wave nanochannels

Dirk Grundler

We report spin wave excitations in a nanopatterned antidot lattice fabricated from a 30-nm thick Ni80Fe20 film. The 250-nm-wide circular holes are arranged in a rhombic unit cell with a lattice constant of 400 nm. By Brillouin light scattering, we find tha ...

Review and perspectives of electrostatic turbulence and transport studies in the basic plasma physics device TORPEX

Ambrogio Fasoli, Ivo Furno, Paolo Ricci, Christian Gabriel Theiler, Joaquim Loizu Cisquella, Fabio Avino, Kyle Gustafson, Alexandre Dominique Bovet

TORPEX is a basic plasma physics toroidal device located at the CRPP-EPFL in Lausanne. In TORPEX, a vertical magnetic field superposed on a toroidal field creates helicoidal field lines with both ends terminating on the torus vessel. We review recent advan ...

Effect of the TEM Mode on the Kicker Impedance

Carlo Zannini, Giovanni Rumolo

The kickers are major contributors to the CERN SPS beam coupling impedance. As such, they may represent a limitation to increasing the SPS bunch current in the frame of a luminosity upgrade of the LHC. The C-Magnet supports a transverse electromagnetic (TE ...

Enhanced functionality in magnonics by domain walls and inhomogeneous spin configurations

Dirk Grundler

This paper discusses nanomagnetic structures enabling the manipulation of propagating spin waves. We address in particular how domain walls, or more generally speaking inhomogeneous spin configurations, enhance the control of spin-wave transmission and the ...

Electroweak lights from Dark Matter annihilations

Andrea De Simone

The energy spectra of Standard Model particles originated from Dark Matter annihilations can be significantly altered by the inclusion of electroweak gauge boson radiation from the final state. A situation where this effect is particularly important is whe ...

Some Fundamental Issues and Verification of 3DEC in Modeling Wave Propagation in Jointed Rock Masses

Jian Zhao, Jianbo Zhu

Discontinuities in rock masses greatly influence stress wave transmission. Before performing numerical modeling on complicated cases, benchmarking modeling must be performed first to validate the numerical code through comparison with theoretical solutions ...
