Ion Beam Etching: Replication of Micro Nano-structured 3D Stencil Masks

Jürgen Brugger, Luis Guillermo Villanueva Torrijo

Ion beam LIGA allows the etching of 3D nano-structures by direct writing with a nano-sized beam. However, this is a relatively time consuming process. We propose here another approach for etching structures on large surfaces and faster, compared to the dir ...

ResIn: A Combination of Result Caching and Index Pruning for High-performance Web Search Engines

Gleb Skobeltsyn

Results caching is an efficient technique for reducing the query processing load, hence it is commonly used in real search engines. This technique, however, bounds the maximum hit rate due to the large fraction of singleton queries, which is an important l ...

Variable latency speculative addition: A new paradigm for arithmetic circuit design

Paolo Ienne, Philip Brisk, Ajay Kumar Verma

Adders are one of the key components in arithmetic circuits. Enhancing their performance can significantly improve the quality of arithmetic designs. This is the reason why the theoretical lower bounds on the delay and area of an adder have been analysed, ...

Defect levels of dangling bonds in silicon and germanium through hybrid functionals

Alfredo Pasquarello, Peter Broqvist, Audrius Alkauskas

Defect levels of dangling bonds in silicon and germanium are determined within their respective band gaps through the use of hybrid density functionals. To validate our approach, we first considered the dangling bond in silicon finding two well-separated d ...

Impact of small amounts of swelling clays on the physical properties of debris-flow-like granular materials. Implications for the study of alpine debris flow

Paul Bowen, Pascal Boivin, Eric Bardou

The effect of the small fraction of clays on the rheological behaviour of alpine debris flow is poorly understood. This is partly due to the complexity of the debris flow mineralogy and the broad particle size distribution. This study has investigated this ...

Charged excitons in modulation-doped quantum wires

Elyahou Kapon, Benjamin Dwir, Marc-André Dupertuis, Daniel Oberli, Nicolas Moret

We report on the observation of negatively- and positively-charged excitons in the photoluminescence spectra of V-groove quantum wires. The. charged exciton binding energy increases with the strength of the quantum confinement. We demonstrate that fluctuat ...

On the Discrete Logarithm Problem on Algebraic Tori

Robert Granger

Using a recent idea of Gaudry and exploiting rational representations of algebraic tori, we present an index calculus type algorithm for solving the discrete logarithm problem that works directly in these groups. Using a prototype implementation, we obtain ...

Melting experiments of a chondritic meteorite between 16 and 25 GPa: Implication for Na/K fractionation in a primitive chondritic Earth's mantle

Philippe Gillet

Melting experiments at high-pressure and temperature were conducted at pressures from 16 to 25 GPa using chondritic starting material but with slightly enhanced Na- and K-contents while keeping the chondritic Na/K ratio constant. The experiments revealed t ...

Pade-Jacobi Approximants

Jan Sickmann Hesthaven

We discuss projection based Pad ́e-Jacobi approximants in general and present in particular an exact rational approximation to the Sign function. This serves as vehicle to analyze the behavior of Pad ́e-Jacobi approximants for discontinuous functions. The ...
