Finding the ground state of a fermionic Hamiltonian using quantum Monte Carlo is a very difficult problem, due to the Fermi sign problem. While still scaling exponentially, full configuration-interact...
Incorporating Forcing Terms in Cascaded Lattice-Boltzmann Approach by Method of Central Moments
Incorporating Forcing Terms Cascaded Lattice-Boltzmann Approach Central Moments
2012/2/29
Cascaded lattice-Boltzmann method (Cascaded-LBM) employs a new class of collision operators aiming to improve numerical stability. It achieves this and distinguishes from other collision operators, su...
An equation-free approach to coarse-graining the dynamics of networks
equation-free approach coarse-graining dynamics of networks
2012/2/29
We propose and illustrate an approach to coarse-graining the dynamics of evolving networks (networks whose connectivity changes dynamically). The approach is based on the equation-free framework: shor...
Prediction of equilibrium Li isotope fractionation between minerals and aqueous solutions at high P and T: an efficient ab initio approach
Li isotope fractionation equilibrium minerals aqueous
2011/8/11
Abstract: The mass-dependent equilibrium stable isotope fractionation between different materials is an important geochemical process. Here we present an efficient method to compute the isotope fracti...
Multiscale approach for bone remodeling simulation based on finite element and neural network computation
Multiscale Hierarchical Bone remodeling Finite element Neural network
2011/8/5
Abstract: The aim of this paper is to develop a multiscale hierarchical hybrid model based on finite element analysis and neural network computation to link mesoscopic scale (trabecular network level)...
Non-perturbative heterogeneous mean-field approach to epidemic spreading in complex networks
Non-perturbative heterogeneous mean-field approach epidemic spreading complex networks
2011/9/9
Since roughly a decade ago, network science has focussed among others on the problem of how the spreading of diseases depends on structural patterns. Here, we contribute to further advance our underst...
Analytic approach for calculating transmitted electromagnetic fields through a slot array in deep sub-wavelength regime
calculating transmitted electromagnetic fields deep sub-wavelength regime
2011/9/5
For the di raction of an incident plane electromagnetic wave by a slotted metallic lm, the previous analytical calculation for a single slot [Technical Phys. 50, 1076 (2005)] is generalized into a mo...
Computational approach to multifractal music
Fractal, Fractal dimension, Mulifractality, Singularity spectrum
2011/9/1
In this work we perform a fractal analysis of 160 pieces of music belonging to six different genres. We show that the majority of the pieces reveal characteristics that allow us to classify them as ph...
Wave approach for the resonances of rectangular and triangular membranes
Wave approach rectangular and triangular
2011/8/31
This study develops a ray technique for determining the resonance frequencies of triangular membranes. The technique is demonstrated for homogenous rectangular and triangular membranes with fixed boun...

The Complemented System Approach: A Novel Method for Calculating the X-ray Scattering from Computer Simulations
Complemented System Approach Method for Calculating the X-ray Scattering Computer Simulations
2010/11/19
In this paper, we review the main problem concerning the calculation of X-ray scattering of simulated model systems, namely their finite size. A novel method based on the Rayleigh–Debye–Gans approxima...
The Gelfand spectrum of a noncommutative C*-algebra: a topos-theoretic approach
Gelfand spectrum noncommutative C*-algebra topos-theoretic approach
2010/11/11
We compare two influential ways of defining a generalized notion of space. The first, inspired by Gelfand duality, states that the category of 'noncommutative spaces' is the opposite of the category o...
Modeling long-memory processes by stochastic difference equations and superstatistical approach

2010/7/5
It is shown that the Poissonian-like process with slowly diffusing-like time-dependent average interevent time may be represented as the superstatistical one and exhibits 1= f noise. The distribution ...
