Dynamics of Quantum Particles in Perturbed Parabolic 2d Potential [PDF]
Журнал нано- та електронної фізики, 2016 2d quantum-mechanical problem of the time evolution of a particle in a quadratic potential is studied. We suppose that the center of the potential is displaced in arbitrary way in time.

Joint Estimation Using Quadratic Estimating Function
Journal of Probability and Statistics, 2011 A class of martingale estimating functions is convenient and plays an important role for inference for nonlinear time series models. However, when the information about the first four conditional moments of the observed process becomes available, the ...

Natural Exponential Families with Quadratic Variance Functions
The Annals of Statistics, 1982 The normal, Poisson, gamma, binomial, and negative binomial distributions are univariate natural exponential families with quadratic variance functions (the variance is at most a quadratic function of the mean). Only one other such family exists. Much theory is unified for these six natural exponential families by appeal to their quadratic variance ...

Bayes Empirical Bayes Estimation for Natural Exponential Families with Quadratic Variance Functions
The Annals of Statistics, 1991 The prior distribution of the parameter of natural exponential families with quadratic variance is estimated by orthogonal polynomials. The proposed approach is based on combinations of Bayesian and nonparametric empirical Bayes methods.

Diagnostics on the cost-function in variational assimilations for meteorological models [PDF]
Nonlinear Processes in Geophysics, 2014 Several consistency diagnostics have been proposed to evaluate variational assimilation schemes. The "Bennett-Talagrand" criterion in particular shows that the cost-function at the minimum should be close to half the number of assimilated observations ...
