Long-range correlations in disordered metals
Physical Review B, 1988We address the problem of conductance fluctuations in real space. The nonlocal conductivity tensor and its correlation functions are calculated from the Kubo formula and are shown to exhibit long-ranged behavior. We offer a physical interpretation of our results.

Long-range correlations for conservative dynamics
Physical Review A, 1990We investigate the origin of long-range spatial correlations in certain anisotropic translation-invariant stationary nonequilibrium states of systems with conservative dynamics. We consider both lattice-gas models with anisotropic but reflection-invariant stochastic dynamics and driven diffusive systems described by a Ginzburg-Landau equation with an ...

LONG RANGE CORRELATION IN HUMAN WRITINGS
Fractals, 1993We study long range correlation in various human writings by mapping them into a simple 1d random walk model. This approach allows us to obtain better quality scaling data than the traditional power spectrum methods. Optimally written computer programs seem to have the highest scaling exponent, i.e., close to that of ideal 1/f noise.

The previous chapter examined the return distributions of the words in a text. Another way to examine returns is in terms of how they succeed one another. As we will see here and in the following chapter, in a natural language text, a short return is likely to follow a series of short returns, and a long return is likely to follow a series of long ...

Long-range correlations in nucleotide sequences
Nature, 1992DNA sequences have been analysed using models, such as an n-step Markov chain, that incorporate the possibility of short-range nucleotide correlations. We propose here a method for studying the stochastic properties of nucleotide sequences by constructing a 1:1 map of the nucleotide sequence onto a walk, which we term a 'DNA walk'.

Physical Review Letters, 1973
Recent S-matrix arguments for the existence of nonplanar contributions to scattering amplitudes are reviewed and compared with experiment. The correct normalization of the two-particle correlation function is discussed. (auth)

Long-range correlations in dusty plasmas
Physics of Plasmas, 1997The correlations in dusty plasmas in the gaseous state is considered. It is shown that the long-ranged correlations of dust particles, contrary to usual matter, start to form in a weakly correlated state, leading finally to the formation of dust crystals and dust liquids with not strong but intermediate strength correlations.

Long Range Correlations between nucleotide triplets
Proceedings of the 6th International Symposium on Health Informatics and Bioinformatics, 2011The study of statistical fluctuations in DNA sequences can reveal important characteristics of their organization. Particularly, in the last two decades, several studies have focused on the detection of Long Range Correlations (LRC) in DNA sequences, and on the study of particular long range dependence properties of nucleotides. Since protein coding is

Long range correlations and the onset of chemical instabilities [PDF]
Physica A: Statistical Mechanics and its Applications, 1976 Abstract Recent analyses of fluctuations in non-equilibrium systems by Prigogine, Malek-Mansour and Nicolis have indicated the existence of a minimal coherence length beyond which fluctuations can amplify and induce instabilities at a macroscopic scale.

Long-range orientation correlation in water
The Journal of Chemical Physics, 2014Strong short-range intermolecular interactions result in position and orientation correlations between nearest neighbour molecules in isotropic liquids, but it is generally assumed that such correlations extend at most a few molecular diameters. Results from second-harmonic light scattering experiments presented here reveal long-range molecular ...
