Ionization and fragmentation of water clusters by fast highly charged ions

We study the dissociative ionization of water clusters by impact of 12 MeV/u Ni25+ ions. Cold target recoil ion momentum spectroscopy (COLTRIMS) is used to obtain information about stability, energetics and charge mobility of the ionized water clusters. An ...

A comprehensive gyrokinetic description of global electrostatic microinstabilities in a tokamak

Laurent Villard, Stephan Brunner, Paolo Angelino

It is believed that low frequency microinstabilities such as ion temperature gradient (ITG) driven modes and trapped electron modes (TEMs) are largely responsible for the experimentally observed anomalous transport via the ion and electron channels in a to ...

Evidence of inception horizons in karst conduit networks

Laurent Tacher, Marco Filipponi, Pierre-Yves Jeannin

This paper outlines the conclusion from an analysis of 18 large cave systems around the world, comprising more than 1500 km of conduits. The 3D geometry of complex cave systems have been analysed in relation to their geological context as well as their hyd ...

Sharing is Harder than Agreeing

Rachid Guerraoui

One of the most celebrated results of the theory of distributed computing is the impossibility, in an asynchronous system of

n

processes that communicate through shared memory registers, to solve the set agreement problem where the processes need to deci ...

Apraxia: a review

Olaf Blanke, Aude Billard, Biljana Petreska von Ritter-Zahony

Praxic functions are frequently altered following brain lesion, giving rise to apraxia - a complex pattern of impairments that is difficult to assess or interpret. In this chapter, we review the current taxonomies of apraxia and related cognitive and neuro ...

Variational Image Reconstruction from Arbitrarily Spaced Samples: A Fast Multiresolution Spline Solution

Michaël Unser, Michael Sühling, Muthuvel Arigovindan

We propose a novel method for image reconstruction from nonuniform samples with no constraints on their locations. We adopt a variational approach where the reconstruction is formulated as the minimizer of a cost that is a weighted sum of two terms: 1) the ...

Influence of the substrate's surface morphology and chemical nature on the nucleation and growth of microcrystalline silicon

Arvind Shah, Xavier Niquille, Julien Claude Bailat

Hydrogenated microcrystalline silicon (μc-Si:H) layers about 500 nm thick were deposited in the same run on flat and rough substrates (rms = 60 nm) of various chemical nature. This study reveals that the spatial distribution of the microcrystalline/amorpho ...

Adjustable illumination or detection beam pinhole for laser scanning microscope has two knife blades with triangular apertures moving in front of slit with lamp and optical detector

Theo Lasser, Thomas Sidler, Antonio Lopez, Ronald Gianotti

The invention relates to an adjustable pinhole, especially for the illumination beam path and/or detection beam path of a laser scanning microscope. Said pinhole consists of at least two planar basic components comprising articulation points in the form of ...

A generalized correlation for equilibrium of forces in liquid-solid fluidized beds

Albert Renken

A review of publication on the expansion of fluidized bed with the fluid velocity. The well-known Richardson-Zaki equation is applied to develop a more accurate relation linking the apparent drag force Fd, the effective gravitational force Fg, and the void ...

Electron beam induced deposition of rhodium nanostructures

Fabio Cicoira

Electron Beam Induced Deposition (EBID) allows deposition of three-dimensional micro- and nano-structures of conductive and insulating materials on a wide range of substrates. The process is based on the decomposition of molecules of a pre-selected precurs ...
