Competition between cooling and shortwave radiation in shaping near-surface convection in pelagic waters of Lake Geneva

When lake surface waters above the temperature of maximum density 4◦C cools, the verysurface fluid parcels become denser than their neighbours below. The latter process leads to a gravitationally unstable density distribution which may trigger ‘free convec ...

Multi-degree-of-freedom low-frequency electroacoustic absorbers through coupled resonators

Hervé Lissek, Etienne Thierry Jean-Luc Rivet, Sami Driss Karkar

Electroacoustic absorbers represent an interesting solution for low-frequency sound absorption in rooms. These systems simply consist of closed-box electrodynamic loudspeakers, whose acoustic impedance at the diaphragm is judiciously adjusted by connecting ...

Spin Noise Detection of Nuclear Hyperpolarization at 1.2K

Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud

We report proton spin noise spectra of a hyperpolarized solid sample of commonly used DNP (dynamic nuclear polarization) juice containing TEMPOL (4-hydroxy-2,2,6,6-tetramethylpiperidine N-oxide) and irradiated by a microwave field at a temperature of 1.2K ...

Mechanical Characterization and Shape Optimization of Fascicle-Like 3D Skeletal Muscle Tissues Contracted with Electrical and Optical Stimuli

Mahmut Selman Sakar

In this study, we present a quantitative approach to construct effective 3D muscle tissues through shape optimization and load impedance matching with electrical and optical stimulation. We have constructed long, thin, fascicle-like skeletal muscle tissue ...

Majority Logic Synthesis for Spin Wave Technology

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Luca Gaetano Amarù, Odysseas Zografos

Spin Wave Devices (SWDs) are promising beyond-CMOS candidates. Unlike traditional charge-based technologies, SWDs use spin as information carrier that propagates in waves. In this scenario, the logic primitive for computation is the majority gate. T ...

Characterization method of dielectric properties of free falling drops in a microwave processing cavity and its application in microwave internal gelation

Manuel Alexandre Pouchon, Sébastien Vaucher, Cédric Cozzo

Microwave internal gelation (MIG) is a chemical process proposed for the production of nuclear particle fuel. The internal gelation reaction is triggered by a temperature increase of aqueous droplets falling by gravity by means of non-contact microwave hea ...

Generation and application of dynamic gratings in optical fibers using stimulated Brillouin scattering

Luc Thévenaz, Nikolay Primerov

Since the invention of optical fiber cable data transmission using light has become ubiquitous in the past years. Nonlinear optical effects, which are hardly noticed in our daily life, have become crucial and highly influential for the design and performan ...

Effect of realistic modeling of deep brain stimulation on the prediction of volume of active tissue

Juan Ramon Mosig, Laleh Golestanirad

Deep brain stimulation (DBS) is a well-established treatment for Parkinson's disease, essential tremor and dystonia. It has also been successfully applied to treat various other neurological and psychiatric conditions including depression and obsessive-com ...

Switching field modulation of a nanomagnet by resonant microwave spin torque

Jean-Philippe Ansermet, Elena Murè

We report on the effect of a low amplitude microwave current on the switching field of magnetic layers in a 40 nm diameter pseudo-spin valve grown by template synthesis. We show a frequency dependence at room temperature reflecting the dynamic behavior of ...

An Ultralow-Power UHF Transceiver Integrated in a Standard Digital CMOS Process: Transmitter

Christian Enz

In the first part of the paper, also in this issue of the JOURNAL, the design of the frequency synthesizer and receiver section of an FSK transceiver was described. It operates in the 434-MHz ISM (Industrial, Scientific, Medical) band and is realized in a ...
