The relevant space-time correlation function for a reaction of type A + M → B + C is a one-particle Green's function describing creation and propagation of an "M hole".doi:10.1016/0009-2614(86)87172-XM.D. GirardeauC.I. Ivanov

As a result, each spatial frequency kx is associated with a single temporal frequency ω, with a delta-function correlation whose functional form depends on θ, kx = kx(ω, θ)42,70. Consequently, the envelope ψ(x, z, t) of the wave packet \(E(x,z,t)={e}^{i({k}_{{\...
The structure of nanocrystal superlattices has been extensively studied and well documented, however, their assembly process is poorly understood. In this work, we demonstrate an in situ space- and time-resolved small angle X-ray scattering measurement t
Measurements of the space—time correlation function of images at the focus of a large telescope have been made. They indicate that the image boiling has a directional component that is parallel to the motion of the turbulence in the pupil plane. 关键词: Astronomical Photography Cross Correlation...
To cope with high space-time resolution of data, the local Gaussian models use a Markov representation of the Matérn correlation function based on the stochastic partial differential equations (SPDE) approach. In the second step, they are fitted in a Bayesian framework through the integrated ...
Animpulse response function(IRF) of a state-space model (ordynamic response of the system) measures contemporaneous and future changes in the state and measurement variables when each state-disturbance variable is shocked by a unit impulse at period 1. In other words, the IRF at timetis the ...
We identified for the first time the clear occurrence of recently-diagnosed TB hotspots, and quantified potential benefit of increased community ART coverage in lowering tuberculosis, highlighting the need to prioritize the expansion of such effective population interventions targeting high-risk areas....
In many real-world situations there is a cost both for more hidden states and for more hidden timesteps. Accordingly, we derive a “space–time” tradeoff between the number of hidden states and the number of hidden timesteps needed to implement any given function....
