Singular Sets Of Higher Order Elliptic Equations (2007)
Qing Han, Robert Hardt, Fanghua Lin
Introduction The implicit function theorem implies that the zero set of a smooth function, the set where the function vanishes, is a smooth hypersurface away from the critical zero set. Hence to...
Local solutions to a class of Monge-Ampère equations of mixed type (2007)
In this article, we study a class of Monge-Ampère equations of mixed type which is elliptic in one side of a hypersurface and hyperbolic in another side. The degeneracy along the hypersurface is...
Han, Qing, Shimura, Atsushi, Inagaki, Keizo, Ohira, Takashi, Akaike, Masami
This paper presents a trial fabricated GaAs monolithic anti-series varactor pair. Its second-order and third-order harmonic distortions, which are generated from the nonlinearity of...
A Compact Espar Antenna with Planar Parasitic Elements on a Dielectric Cylinder (2005)
HAN, Qing, HANNA, Brett, OHIRA, Takashi
This paper presents a technique for designing a dielectric Electronically Steerable Parasitic Array Radiator (Espar) antenna to achieve miniaturization of the conventional Espar antenna. The...
HAN, Qing, INAGAKI, Keizo, OHIRA, Takashi
Nonlinear distortions in an anti-series varactor pair (ASVP) are analyzed by a perturbation method. To the authors' knowledge, this paper presents the first derivation of an analytical expression...
Sooner and later waiting time problems for patterns in Markov dependent trials (2003)
In this paper, we investigate sooner and later waiting time problems for patterns S0 and S1 in multistate Markov dependent trials. The probability functions and the probability generating functions...
Local Isometric Embedding of Surfaces with Nonpositive Gaussian Curvature (2003)
Han, Qing, Hong, Jia-Xing, Lin, Chang-Shou
In this paper, we prove the existence of an isometric embedding near the origin in R3 of a two-dimensional metric with nonpositive Gaussian curvature. The Gaussian curvature can be allowed to be...
Linearity of homogeneous order one solutions to elliptic equations in dimension three (2002)
Han, Qing, Nadirashvili, Nikolai, Yuan, Yu
We prove that any homogeneous order one solution to 3-d nondivergence elliptic equations must be linear.

Waiting time problem for an almost perfect match
Given sequences of finite-state trials, an almost perfect match means that there exists at least k-1 matches between any subsequences of size k in each sequence. Let X1,X2,... be a sequence of...
Let X1, X2,...,Xn be a time-homogeneous {0, 1}-valued Markov chain. Let Y = (Y1,...,Yr) denote the r-dimensional random vector, where Yi(i = l,...,r) represents the number of success runs of length...
