Far field reconstruction from phaseless measurement data
EDP Sciences - Tập 2 - Trang 318-320 - 1997
A new method on phase inverse problem in near field far field transformation is presented in this paper. It makes the relation very clear between phase and amplitude on a curve surface and another surface by describing the relation of the fields on two closed curve surfaces by matrix. Comparing with the other created functionals, the functional based on this method belongs in real space rather tha......
Synthesis, structure and antitumor activities of [Ni(dien)2][Ni(CN)4] complex
EDP Sciences - Tập 9 - Trang 229-233 - 2004
Ni(II)-dien complex was prepared and characterized by X-ray diffraction. The crystal belongs to triclinic system, space group P-1, with crystallographic parametersa=0.888 13(18) nm,b=0.890 10(18) nm,c=1. 591 8(3) nm, α=77.71(3)°, β=89.12(3)°, γ=61.24(3)°,Z=2. The two dien molecules coordinate to the central Ni atom, the six nitrogen atoms form a distorted octahedron. Preliminary pharmacological te......
Asymptotic behavior of solutions for the one-dimensional drift-diffusion model in the quarter plane
EDP Sciences - Tập 19 Số 2 - Trang 144-148 - 2014
In this paper, we study the classical drift-diffusion model arising from the semiconductor device simulation, which is the simplest macroscopic model describing the dynamics of the electron and the hole. We prove the global existence of strong solutions for the initial boundary value problem in the quarter plane. In particular, we show that in large time, these solutions tend to the nonlinear diff......
Investigation of radio ray-path and electron density slope of the ionosphere
EDP Sciences - Tập 3 - Trang 449-452 - 1998
The three dimensional ray-path equation considering the effect of the horizontal gradient of the ionospheric electron density is obtained. By integrating in upgoing and downgoing stage, the point on the raypath can be determined and the propagation channel in HF radio telecommunication may be recknoed and predicted. Considering the effect of the electron density slope the ray-path is asymmetric ab......
Chromosomal localization of a quail homeobox gene: Quox-1
EDP Sciences - Tập 2 - Trang 509-510 - 1997
Quox-1 is an Antp-like homeobox gene of quail embryo whose expression occurs throughout the developing central nervous system. Using a Dig-labeled probe, we localized quox-1 gene on the terminal region of the long arm of quail's chromosome 1 by ISH.
Effect of land use on soil properties in debris flow bottomland: A case study at Xiaojiang Basin, Yunnan
EDP Sciences - Tập 11 Số 4 - Trang 870-874 - 2006
New method on constructing analytic potential function of diatomic molecules
EDP Sciences - Tập 13 - Trang 212-216 - 2008
A new method on constructing analytical potential energy functions is presented, and then a relatively universal analytical potential energy function for precisely calculating the spectra of diatomic molecules and ions is derived. Furthermore, six kinds of common potential energy curves containing three main potential curves i.e. steady state, metastable state and repulsive state are obtained from......
Generalized solution of a class of singularly perturbed robin problems for nonlinear reaction diffusion equation
EDP Sciences - Tập 19 - Trang 149-152 - 2014
A class of singularly perturbed Robin problems for reaction diffusion equation is considered. Under suitable conditions the asymptotic behavior of the generalized solution for the problems are studied.
