Drying front and water content dynamics during evaporation from sand delineated by neutron radiography

Evaporative drying of porous media is jointly controlled by external ( atmospheric) conditions and by media internal transport properties. Effects of different atmospheric potential evaporative demand on observed drying rates were studied in a series of la ...

Evaluating automated parameter constraining procedures of neuron models by experimental and surrogate data

Henry Markram, Felix Schürmann, Sean Lewis Hill, Thomas Berger, Idan Segev

Neuron models, in particular conductance-based compartmental models, often have numerous parameters that cannot be directly determined experimentally and must be constrained by an optimization procedure. A common practice in evaluating the utility of such ...

A virtual valve for smooth contamination-free flow switching

Philippe Renaud, Thomas Michael Braschler, Harald Van Lintel, Nicolas Demierre, Anja Kunze, Raphaël Tornay, Joël Theytaz, Mario Schlund, Grazia Loche

We present a channel geometry that allows for clean switching between different inlets of a microchip without any contamination of the inlets or the downstream flow. We drive this virtual valve with a pneumatic pressure setup that minimizes disturbance of ...

The EDC3 chronology for the EPICA Dome C ice core

Jérôme Chappellaz

Four halons (H-1301, H-1211, H-2402 and H-1202) have been measured in air samples collected from polar firn from Dome Concordia (Dome C), Antarctica, from Devon Island, Canada and the North Greenland Ice Core Project (NGRIP) site, Greenland. H-2402 and H-1 ...

New constraints on the gas age-ice age difference along the EPICA ice cores, 0-50 kyr

Jérôme Chappellaz

Four trihalomethane (THM; CHCl3, CHBrCl2, CHBr 2Cl and CHBr3) and two dihalomethane (DHM; CH 2BrCl and CH2Br2) trace gases have been measured in air extracted from polar firn collected at the North Greenland Icecore Project (NGRIP) site. CHCl3 was also mea ...

Effect of solute dissolution kinetics on cloud droplet formation: Extended Köhler theory

Athanasios Nenes

This study focuses on the importance of solute dissolution kinetics for cloud droplet formation. To comprehensively account for the kinetics, a numerical model of the process was developed. Simulations of cloud droplet growth were performed for solute diff ...

Deformation mechanisms of silicon during nanoscratching

Christophe Ballif, Johann Michler

The deformation mechanisms of silicon {001} surfaces during nanoscratching were found to depend strongly on the loading conditions. Nanoscratches with increasing load were performed at 2 μm/s (low velocity) and 100 μm/s (high velocity). The load-penetratio ...

Practical Cryptography in High Dimensional Tori

Robert Granger, Martijn Stam

At Crypto 2004, van Dijk and Woodruff introduced a new way of using the algebraic tori

T_n

in cryptography, and obtained an asymptotically optimal

n/\phi(n)

savings in bandwidth and storage for a number of cryptographic applications. However, the compu ...

Grammar-Based Tree Compression

Grammar-based compression means to find a small grammar that generates a given object. Such a grammar reveals the structure of the object (according to the grammar formalism used); the main advantage of this compression method is that the resulting grammar ...

A Comparison of CEILIDH and XTR

Robert Granger, Martijn Stam

We give a comparison of the performance of the recently proposed torus-based public key cryptosystem CEILIDH, and XTR. Underpinning both systems is the mathematics of the two dimensional algebraic torus
