Inverting the Angular Correlation Function [PDF]

, 1999
The two point angular correlation function is an excellent measure of structure in the universe. To extract from it the three dimensional power spectrum, one must invert Limber's Equation.

Density of States for a specified correlation function and the energy landscape. [PDF]

Physical Review Letters, 2012
The degeneracy of two-phase disordered microstructures consistent with a specified correlation function is analyzed by mapping it to a ground-state degeneracy.

Constructing the correlation function of four stress-tensor multiplets and the four-particle amplitude in N=4 SYM [PDF]

, 2012
We present a construction of the integrand of the correlation function of four stress-tensor multiplets in N = 4 SYM at weak coupling. It does not rely on Feynman diagrams and makes use of the recently discovered symmetry of the integrand under ...

A New Coefficient of Correlation [PDF]

Journal of the American Statistical Association, 2019
–Is it possible to define a coefficient of correlation which is (a) as simple as the classical coefficients like Pearson’s correlation or Spearman’s correlation, and yet (b) consistently estimates some simple and interpretable measure of the degree of ...

Simulation and Experiment of Substation Grounding Resistance Measurement Based on Pseudorandom Signal

Sensors, 2022
The grounding resistance of a substation is an important parameter that should be designed within a reasonable range to prevent operational accidents from damaging electrical equipment due to overvoltage and ensure the safe operation of an electrical ...

Correlation function of dyonic strings

, 2011
We investigate the two- and three-point correlation functions of the dyonic magnon and spike, which correspond to the solitonic string moving in the Poincare AdS and three-dimensional sphere. We show that the coupling between two dyonic magnons or spikes

QCD sum rules with two-point correlation function [PDF]

, 1999
We construct three different sum rules from the two-point correlation function with pion, $i\int d^4x e^{iq\cdot x} $, beyond the soft-pion limit. The PS and PV coupling schemes in the construction of the phenomenological side are carefully considered in
