Molecular quenching and relaxation in a plasmonic tunable system

Molecular fluorescence decay is significantly modified when the emitting molecule is located near a plasmonic structure. When the lateral sizes of such structures are reduced to nanometer-scale cross sections, they can be used to accurately control and amp ...

Forcing independent velocity distributions in an experimental granular fluid

Pedro Miguel Nunes Pereira de Almeida Reis

We present experimental results on the velocity statistics of a granular fluid with an effective stochastic thermostat, in a quasi-two-dimensional configuration. We find the base state, as measured by the single particle velocity distribution P(c) in the c ...

Visual Focus of Attention Estimation from Head Pose Posterior Probability Distributions

Jean-Marc Odobez, Silèye Oumar Ba

We address the problem of recognizing the visual focus of attention (VFOA) of meeting participants from their head pose and contextual cues. The main contribution of the paper is the use of a head pose posterior distribution as a representation of the head ...

Matrix effects on the optical response of silver nanoclusters

Sylvain Lecoultre, Alexandre Rydlo, Fabien Conus

We report absorption spectra for Ag7, Ag9, and Ag11 in an argon matrix grown at a temperature of 28 K and compare them with previous spectra of the same species measured in matrices of argon grown at lower temperatures as well as in neon matrices. We discu ...

Analytic Determination of Scaling Parameters

Rüdiger Urbanke, Abdelaziz Amraoui, Andrea Montanari

We show that the finite-length scaling parameters for irregular LDPC codes when used over the binary erasure channel can be computed without resorting to ``covariance evolution''. We provide simple expressions that can be evaluated using solely the degree ...

Finite length analysis of LT codes

Mohammad Amin Shokrollahi

This paper provides an efficient method for analyzing the error probability of the belief propagation (BP) decoder applied to LT Codes. Each output symbol is generated independently by sampling from a distribution and adding the input symbols corresponding ...

Analysis of the initial fragmentation stage of oxide coatings on polymer substrates under biaxial tension

Yves Leterrier

Crack patterns of 100-nm thick silicon oxide coatings on poly(ethylene terephthalate), polypropylene and polyamide films are analyzed under equibiaxial stress loading. The loading is achieved by means of a bulging cell mounted under an optical microscope w ...

Block algorithms for orthogonal symplectic factorizations

Daniel Kressner

On the basis of a new WY-like representation block algorithms for orthogonal symplectic matrix factorizations are presented. Special emphasis is placed on symplectic QR and URV factorizations. The block variants mainly use level 3 (matrix-matrix) operation ...

The local minority game

Paolo De Los Rios

Ecologists and economists try to explain collective behavior in terms of competitive systems of selfish individuals with the ability to learn from the past. Statistical physicists have been investigating models which might contribute to the understanding o ...
