Optimal estimation of low rank density matrices
The density matrices are positively semi-definite Hermitian matrices of unit trace that describe the state of a quantum system. The goal of the paper is to develop minimax lower bounds on error rates of estimation of low rank density matrices in trace regression models used in quantum state tomography (in particular, in the case of Pauli measurements) with explicit dependence of the bounds on t...
متن کاملa swot analysis of the english program of a bilingual school in iran
با توجه به جایگاه زبان انگلیسی به عنوان زبانی بین المللی و با در نظر گرفتن این واقعیت که دولت ها و مسئولان آموزش و پرورش در سراسر جهان در حال حاضر احساس نیاز به ایجاد موقعیتی برای کودکان جهت یاد گیری زبان انگلیسی درسنین پایین در مدارس دو زبانه می کنند، تحقیق حاضر با استفاده از مدل swot (قوت ها، ضعف ها، فرصتها و تهدیدها) سعی در ارزیابی مدرسه ای دو زبانه در ایران را دارد. جهت انجام این تحقیق در م...
15 صفحه اولFrequency-eecient Coding with Low-density Generator Matrices
In a recent paper, it is shown that if Pearl's belief propagation algorithm is applied to the Bayesian belief network of a turbo code, the turbo decoding algorithm immediately results. From this perspective, it is recognized that the turbo coding structure imposes unnecessary diierentiation on the parity checks and the turbo decoding algorithm speciies a seemingly arbitrary sequential activatio...
متن کاملLow density lipoprotein kinetics in a family having defective low density lipoprotein receptors in which hypercholesterolemia is suppressed.
Heterozygous familial hypercholesterolemia (FH) usually presents with severe elevations of low density lipoprotein (LDL) cholesterol. Recently, a family with FH was described in which several members heterozygous for a mutation in the LDL receptor gene had normal LDL cholesterol levels. Kinetic studies of LDL apolipoprotein B (apo B) were conducted to determine the metabolic differences between...
متن کاملJoint Source/Channel Coding with Low Density Parity Check Matrices
The objectives of this paper are two-fold, first to present the problem of joint source and channel coding from a graphical model perspective and second to propose a structure that uses a new graphical model for jointly encoding and decoding of a redundant source. In the first part of the paper, relevant contributions to joint source and channel coding, ranging from the Slepian-Wolf problem to ...
