Density derivative estimation for stationary and strongly mixing data
Alexandria Engineering Journal, 2020 Estimation of density derivatives has found multiple uses in statistical data analysis. An inefficient two-step method to obtain it is estimating the density and then computing the derivatives.

Asymptotic Deconfinement in High-Density QCD [PDF]
Physical Review Letters, 2001 We discuss QCD with two light flavors at large baryon chemical potential mu. Color superconductivity leads to partial breaking of the color SU(3) group. We show that the infrared physics is governed by the gluodynamics of the remaining SU(2) group with an exponentially soft confinement scale Lambda_QCD' Delta*exp[-a*mu/(g*Delta)], where Delta<

Asymptotic Expansion of Risk-Neutral Pricing Density
International Journal of Financial Studies, 2018 A new method for pricing contingent claims based on an asymptotic expansion of the dynamics of the pricing density is introduced. The expansion is conducted in a preferred coordinate frame, in which the pricing density looks stationary.

Semi-Parametric Estimation Using Bernstein Polynomial and a Finite Gaussian Mixture Model
Entropy, 2022 The central focus of this paper is upon the alleviation of the boundary problem when the probability density function has a bounded support. Mixtures of beta densities have led to different methods of density estimation for data assumed to have compact ...

Asymptotic Convergence of Soft-Constrained Neural Networks for Density Estimation
Mathematics, 2020 A soft-constrained neural network for density estimation (SC-NN-4pdf) has recently been introduced to tackle the issues arising from the application of neural networks to density estimation problems (in particular, the satisfaction of the second ...

Spectral analysis of vibration in weakly non-linear systems
Vietnam Journal of Mechanics, 2000 The weakly nonlinear systems subjected to deterministic excitations have been fully and deeply studied by use of the well developed asymptotic methods [1-4].

POSITIVITY OF QCD AT ASYMPTOTIC DENSITY [PDF]
Strong and Electroweak Matter 2002, 2003 In this talk, I try to show that the sign problem of dense QCD is due to modes whose frequency is higher than the chemical potential. An effective theory of quasi-quarks near the Fermi surface has a positive measure in the leading order. The higher-order corrections make the measure complex, but they are suppressed as long as the chemical potential is ...
