Correlation functions and factorial correlator data

Physical Review D, 1991
The close connection between factorial moments and factorial correlators as integrals of the same underlying correlation function is explored, leading to extensions of sum rules previously suggested. Cumulants, which were previously found to be the fundamental building blocks for moments, have been analogously defined for the correlators also ...

Functional Neuroimaging Correlates of Functional Amnesia

Memory, 1999
Especially in the field of memory encoding and retrieval, the results of functional neuroimaging have provided new insights in anatomico-functional interactions. In particular this holds true for the role of the prefrontal cortex in mnestic information processing, for the contribution and participation of the two hemispheres in various processes of ...

Correlation Functionals

Journal of Mathematical Physics, 1965
The correlations between positions of particles in classical equilibrium statistical mechanics are usually expressed by correlation functions. It can be seen that if the correlation functions of a system are known, its configurational entropy per unit volume is already determined (independently of the interaction potential or other thermodynamical ...

Gauge-invariant correlation functions

Physical Review D, 1989
A formalism is discussed that gives correlation functions, the poles ofwhich define the physical excitation spectrum in gauge theories. Fermionicexcitations in QED are used as an example. The fermion spectrum in ahigh-temperature plasma is studied as an illustrative application of theformalism. The connection to kinetic theory is made.

Time Correlation Functions

2006
In the previous chapter we have seen how spatial correlation functions express useful structural information about our system. This chapter focuses on time correlation functions that, as will be seen, convey important dynamical information. Time correlation functions will repeatedly appear in our future discussions of reduced descriptions of physical ...

Correlation synthetic discriminant functions

Applied Optics, 1986
Advanced filters are described for distortion-invariant space-invariant object identification and location in clutter using correlators. These correlation synthetic discriminant functions (SDFs) are extensions of earlier projection SDFs. They provide control of the sidelobe levels and the shape of the output correlation function as well as its peak ...

Thermodynamic functions as correlation-function integrals

The Journal of Chemical Physics, 2013
Expressions of some thermodynamic functions as correlation-function integrals, such as the Ornstein-Zernike integral, the Kirkwood-Buff integrals, and the integral formulas for virial coefficients, are recalled. It is noted, as has been remarked before, that the choice of molecular centers from which intermolecular distances are measured is arbitrary ...

Correlation Functions as Hydrodynamic Green's Functions

Physical Review, 1968
A formal solution for the thermodynamic variables describing a system in a nonequilibrium state is given in terms of space- and time-dependent correlation functions. The solution during the hydrodynamic stage is also given by the Green's function solution to the hydrodynamic equations. The correlation functions contain information, not contained in the
