How Efficient Can Gossip Be? (On the Cost of Resilient Information Exchange)

Rachid Guerraoui, Seth Gilbert, Dan Alistarh, Morteza Zadimoghaddam

Gossip, also known as epidemic dissemination, is becoming an in- creasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural ex- tension of the random phone-call ...

Gossip, also known as epidemic dissemination, is becoming an increasingly popular technique in distributed systems. Yet, it has remained a partially open question: how robust are such protocols? We consider a natural extension of the random phone-call mode ...

Distortion of Mappings and $L_{q,p}$-Cohomology

Marc Troyanov

We study some relation between some geometrically defined classes of diffeomorphisms between manifolds and the

L_{q,p}

-cohomology of these manifolds. Some applications to vanishing and non vanishing results in

L_{q,p}

-cohomology are given. ...

Quantum scale invariance on the lattice

Igor Tkachev

We propose a scheme leading to a non-perturbative definition of lattice field theories which are scale-invariant on the quantum level. A key idea of the construction is the replacement of the lattice spacing by a propagating dynamical field - the dilaton. ...

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 ...

Integration of plasmonic optical traps in microfluidics - art. no. 69880V

Olivier Martin, Lina Huang

We study the integration of plasmonic traps with microfluidic channels. Plasmonic traps are optical traps that use the evanescent field generated by metallic nanostructures at their plasmon resonance to trap small objects. Contrary to conventional - far-fi ...

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 ...

Gradient free sol-gel Pb(Zr-x,Ti1-x)O-3 thin films

Paul Muralt, Florian Calame

Pb(Zr-x,Ti1-x)O-3 thin films of homogeneous composition were synthesized by means of a modified sol-gel route on Pt(111)/TiOx/SiO2/Si substrates. The usually observed gradient in B-site composition could be reduced from +/- 12 to +/- 12.5 at% amplitude in ...

Size and microstructure effects on the mechanical behavior of FCC bicrystals by quasicontinuum method

Jean-François Molinari

The effects of structure and size on the deformation of < 110 > tilt bicrystals in copper are investigated by concurrent multiscale simulations at zero temperature. In the simulation of eleven grain boundary (GB) structures, a direct relation is shown betw ...
