Probing the validity of the Derjaguin approximation for heterogeneous colloidal particles

The Derjaguin approximation states that the interaction force between two curved surfaces is proportional to their effective radius, whereby the inverse effective radius is the arithmetic mean of the inverse curvature radii of the surfaces involved. The pr ...

The Impact of Surplus Sharing on the Stability of International Climate Agreements

Juan Carlos Altamirano Cabrera

This paper analyses stability of coalitions for greenhouse gas abatement under different sharing rules applied to the gains from cooperation. We use a 12-region model to examine internal and external stability of coalitions. We determine and compare stable ...

A cross-layer design of wireless ad-hoc networks

We consider a cross-layer design of wireless ad-hoc networks. Traditional networking approaches optimize separately each of the three layers: physical layer, medium access and routing. This may lead to largely suboptimal network designs. In this work, we p ...

Self-similar density turbulence in the TCV tokamak scrape-off layer

Jonathan Graves, Richard Pitts, Jan Horacek

Plasma fluctuations in the scrape-off layer (SOL) of the TCV tokamak exhibit statistical properties which are universal across a broad range of discharge conditions. Electron density fluctuations, from just inside the magnetic separatrix to the plasma-wall ...

On Average Throughput Benefits and Alphabet Size in Network Coding

Christina Fragouli, Emina Soljanin

e analyze a special class of configurations with h sources and N receivers to demonstrate the throughput benefits of network coding and deterministic code design. We show that the throughput benefits network coding offers can increase proportionally to \sq ...

Relationship between L-glutamate-regulated intracellular Na+ dynamics and ATP hydrolysis in astrocytes

Pierre Magistretti, Jean-Yves Chatton

Glutamate uptake into astrocytes and the resulting increase in intracellular Na+ (Na+(i)) have been identified as a key signal coupling excitatory neuronal activity to increased glucose utilization. Arguments based mostly on mathematical modeling led to th ...

Efficient algorithm for band connectivity resolution

Oleg Yazyev

An efficient algorithm for band connectivity (BC) resoln. is presented. The method uses only readily available band coeffs. and the overlap matrix, and has a low computational cost. The accuracy of the BC resoln. is such that the method is practical for me ...

Electrochemical Investigation of Traps in a Nanostructured TiO2 Film

Ulf Anders Hagfeldt

Electron traps at the nanostructured TiO2 (anatase)/aq. electrolyte interface were studied by electrochem. methods. The transient current decays at different potentials pos. of the flatband potential clearly illustrate the trap-filling process. The more ne ...

Power laws for the spatial dependence of electrical parameters in the high-voltage capacitive RF sheath

Christoph Hollenstein, Alan Howling

Following the analytical description of the collisionless high-voltage capacitive RF sheath in Lieberman (1988) and of the collisional high-voltage capacitive RF sheath in Lieberman (1989), electrical sheath parameters are calculated for a square-wave ie R ...

A Note on the Fairness of Additive Increase and Multiplicative Decrease

Jean-Yves Le Boudec, Patrick Thiran, Paul Hurley

Some recent papers [KMT97, MR98] have shown that congestion control based on additive increase and multiplicative decrease tends to share bandwidth according to proportional fairness. Proportional fairness is a form of fairness which distributes bandwidth ...
