Toroidal drift precession and wave - particle interaction in shaped tokamaks with infinite beta and neoclassical equilibrium effects

The drift kinetic equation is analysed for linear instabilities that are sensitive to the toroidal drift motion of long-mean free path particle populations. The interaction Lagrangian is resolved, and the toroidal drift precession evaluated for realistic t ...

Computation over Gaussian networks with orthogonal components

Michael Christoph Gastpar, Chien-Yi Wang

Function computation of arbitrarily correlated discrete sources over Gaussian networks with multiple access components but no broadcast is studied. Two classes of functions are considered: the arithmetic sum function and the frequency histogram function. T ...

First observation of the decay B-s(0) -> (D) over bar (0)phi is reported using pp collision data, corresponding to an integrated luminosity of 1.0 fb(-1), collected by the LHCb experiment at a centre-of-mass energy of 7 TeV. The significance of the signal ...

Lyapunov Exponents of Random Walks in Small Random Potential: The Lower Bound

Thomas Mountford, Jean-Christophe Mourrat

We consider the simple random walk on , d > 3, evolving in a potential of the form beta V, where are i.i.d. random variables taking values in [0, + a), and beta > 0. When the potential is integrable, the asymptotic behaviours as beta tends to 0 of the asso ...

Experimental investigation of collagen waviness and orientation in the arterial adventitia using confocal laser scanning microscopy

Michaël Unser, Nikolaos Stergiopoulos, Daniel Sage, Alessandra Griffa, Aristotelis Agianniotis, Jelle Tymen Christiaan Schrauwen

Mechanical properties of the adventitia are largely determined by the organization of collagen fibers. Measurements on the waviness and orientation of collagen, particularly at the zero-stress state, are necessary to relate the structural organization of c ...

On Reductions for Synthesis Procedures

Viktor Kuncak, Philippe Paul Henri Suter, Swen Jacobs

A synthesis procedure acts as a compiler for declarative specifications. It accepts a formula describing a relation between inputs and outputs, and generates a function implementing this relation. This paper presents synthesis procedures for data structure ...

Eye Vessel Compliance as a Function of Intraocular and Arterial Pressure and Eye Compliance

Nikolaos Stergiopoulos, Sylvain Roy, Adan Villamarin

PURPOSE. The purpose of our study is to develop and validate a methodology to measure the compliance of the vascular network in the eye using biomechanical parameters, namely arterial pressure, intraocular pressure (IOP), and ocular compliance of the eyeba ...

The autocorrelation function for island areas on self-affine surfaces

Jean-François Molinari, Guillaume Anciaux, Srinivasa Babu Ramisetti

The spatial distribution of regions that lie above contours of constant height through a self-affine surface is studied as a function of the Hurst exponent H. If the surface represents a landscape, these regions correspond to islands. When the surface repr ...

Biomechanics and tissue engineering

Dominique Pioletti

Development of artificial scaffold for musculo-skeletal applications, especially in load-bearing situations, requires the consideration of biomechanical aspects for its integrity and its function. However, the biomechanical loading could also be used to fa ...

Betatron squeeze optimisation at the Large Hadron Collider based on first year of operation data

Xavier Buffat

In order to achieve the high luminosity expected from the Large Hadron Collider, the beta function at the interaction points must be minimised. As the aperture in the surroundings of the interaction points become smaller and smaller with decreasing beta fu ...
