Scaled Density Functional Theory Correlation Functionals [PDF]
We show that a simple one-parameter scaling of the dynamical correlation energy estimated by the density functional theory (DFT) correlation functionals helps increase the overall accuracy for several local and nonlocal functionals. The approach taken here has been described as the "scaled dynamical correlation" (SDC) method [Ramachandran, J.

Robust Online Correlation Method for Identification of a Nonparametric Model of Type 1 Diabetes
The paper presents an online version of the identification method for estimating the impulse responses in the case of a two-input single-output linear empirical model of type 1 diabetes that allows us to adapt the model parameters due to the intra ...

Two-point correlation function for Dirichlet L-functions
The two-point correlation function for the zeros of Dirichlet L-functions at a height E on the critical line is calculated heuristically using a generalization of the Hardy-Littlewood conjecture for pairs of primes in arithmetic progression.

Power-law decay of the spatial correlation function in exciton-polariton condensates
We create a large exciton-polariton condensate and employ a Michelson interferometer setup to characterize the short- and long-distance behavior of the first order spatial correlation function.

Correlation Function of Galaxy Groups
We use the Updated Zwicky Catalog of galaxies (Falco et al. 1999) to generate a catalog of groups, by means of a friend-of-friend algorithm. The correlation length of the total sample is well fitted with a power law $ \xi(r)=(r/r_0)^\gamma $ with ...

Random Oscillations of Rail Vehicles with Nonlinear Spring Suspension Characteristics
There is considered about the problem of nonsteady random processes as related to rail vehicle oscillations under action of multidimentional random forcing process in the form of vertical and horizontal irregularities of the left and right rail lines. In

Correlated correlation functions in random-bond ferromagnets [PDF]
The two-dimensional random-bond Q-state Potts model is studied for Q near 2 via the perturbative renormalisation group to one loop. It is shown that weak disorder induces cross-correlations between the quenched-averages of moments of the two-point spin/spin and energy/energy correlation functions, which should be observable numerically in specific ...
