Comment on "Melting of Isolated Tin Nanoparticles"
R. Kofman, P. Cheyssac, F. Celestini
Comment on the paper of T.Bachels, H. J. Güntherodt and R.Schäfer : "Melting of Isolated Tin Nanoparticles".
Exterior algebra methods for the Minimal Resolution Conjecture
David Eisenbud, Sorin Popescu, Frank-Olaf Schreyer +1
If r\geq 6, r\neq 9, we show that the Minimal Resolution Conjecture fails for a general set of m points in P^r for almost 1/2\sqrt r values of m. This strengthens the result of Eis…
Self-Consistent Theory of Rupture by Progressive Diffuse Damage
S. Gluzman, D. Sornette
We analyze a self-consistent theory of crack growth controlled by a cumulative damage variable d(t) dependent on stress history. As a function of the damage exponent , which con…
On a fate of hot quantum field theories
B. Candelpergher, T. Grandou
It is argued that for hot quantum fields, the necessary effective perturbation theories may be based on a resummation procedure which, contrarily to the zero temperature case, diff…
Elastic Response of Rough Surfaces in Partial Contact
G. George Batrouni, Alex Hansen, Jean Schmittbuhl
We model numerically the partial normal contact of two elastic rough surfaces with highly correlated asperities. Facing surfaces are unmated and described as self-affine with a Hur…
Adaptive optics imaging of P Cygni in Halpha
O. Chesneau, M. Roche, A. Boccaletti +6
We obtained Halpha diffraction limited data of the LBV star P Cyg using the ONERA Adaptive Optics (AO) facility BOA at the OHP 1.52m telescope on October 1997. Taking P Cyg and the…
The action of the Frobenius map on rank 2 vector bundles in characteristic 2
Yves Laszlo, Christian Pauly
Let be an ordinary smooth curve defined over an algebraically closed field of characteristic 2. The absolute Frobenius induces a rational map on the moduli space of r…
Drift without flux: Brownian walker with a space dependent diffusion coefficient
P. Lancon, G. Batrouni, L. Lobry +1
Space dependent diffusion of micrometer sized particles has been directly observed using digital video microscopy. The particles were trapped between two nearly parallel walls maki…
Stock Market Speculation: Spontaneous Symmetry Breaking of Economic Valuation
D. Sornette
Firm foundation theory estimates a security's firm fundamental value based on four determinants: expected growth rate, expected dividend payout, the market interest rate and the de…
Diffusion as mixing mechanism in granular materials
C. Henrique, G. Batrouni, D. Bideau
We present several numerical results on granular mixtures. In particular, we examine the efficiency of diffusion as a mixing mechanism in these systems. The collisions are inelasti…
Effect of boundary conditions on diffusion in two-dimensional granular gases
C. Henrique, G. Batrouni, D. Bideau
We analyze the influence of boundary conditions on numerical simulations of the diffusive properties of a two dimensional granular gas. We show in particular that periodic boundary…
Field and intensity correlations in random media
P. Sebbah, R. Pnini, A. Z. Genack
Measurements of the microwave field transmitted through a random medium allows direct access to the field correlation function, whose complex square is the short range or C1 contri…
Evaluation of the quantitative prediction of a trend reversal on the Japanese stock market in 1999
Anders Johansen, Didier Sornette
In January 1999, the authors published a quantitative prediction that the Nikkei index should recover from its 14 year low in January 1999 and reach a year later. T…
Finite-time singularity in the dynamics of the world population, economic and financial indices
Anders Johansen, Didier Sornette
Contrary to common belief, both the Earth's human population and its economic output have grown faster than exponential, i.e., in a super-Malthusian mode, for most of the known his…
The critical earthquake concept applied to mine rockbursts with time-to-failure analysis
G. Ouillon, D. Sornette
We report new tests of the critical earthquake concepts performed on rockbursts in deep South African mines. We extend the concept of an optimal time and space correlation region a…
Increments of Uncorrelated Time Series Can Be Predicted With a Universal 75% Probability of Success
D. Sornette, J. V. Andersen
We present a simple and general result that the sign of the variations or increments of uncorrelated times series are predictable with a remarkably high success probability of 75%…
An adelic causality problem related to abelian L-functions
Jean-Francois Burnol
I associate to a global field K a Lax-Phillips scattering which has the property of causality if and only if the Riemann Hypothesis holds for all the abelian L-functions of K. As a…
