High-Isolation Shunt-Series MEMS Switch for a Wide Frequency Range (6-40GHz)

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia

A fabrication method for silicon beams and membranes defined in lateral and vertical dimensions, as well as superposed silicon membranes, all realized in bulk silicon using only one lithographic step is proposed. This proposal is based on observations made ...

Solids and Supersolids of Three-Body Interacting Polar Molecules on an Optical Lattice

Julien Dorier

We study the physics of cold polar molecules loaded into an optical lattice in the regime of strong three-body interactions, as put forward recently by Buchler et al. [Nature Phys. 3, 726 (2007)]. To this end, quantum Monte Carlo simulations, exact diagona ...

Application of the Kano-Hamilton Multiangle Inversion Method in Clear Atmospheres

Marc Parlange

An improved measurement methodology and a data-processing technique for multiangle data obtained with an elastic scanning lidar in clear atmospheres are introduced. Azimuthal and slope scans are combined to reduce the atmospheric heterogeneity. Vertical pr ...

The role of methane and biogenic volatile organic compound sources in late glacial and Holocene fluctuations of atmospheric methane concentrations

Jed Oliver Kaplan

Recent analyses of ice core methane concentrations suggested that methane emissions from wetlands were the primary driver for prehistoric changes in atmospheric methane. However, these interpretations conflict as to the location of wetlands, magnitude of e ...

Streambank erosion modelling of the River Enrick

John Beck

In the framework of the INTERREG IIIb NWE project « Strategies and Actions for Flood Risk Management » (SAFER), a detailed streambank erosion hazard model applicable to long river reaches has been developed. Streambank erosion has caused significant damage ...
