Parameter Estimation with Mixed-State Quantum Computation
, 2008 We present a quantum algorithm to estimate parameters at the quantum metrology limit using deterministic quantum computation with one bit. When the interactions occurring in a quantum system are described by a Hamiltonian $H= \theta H_0$, we estimate ...

Estimation of Linear Functions of Cell Proportions
The Annals of Mathematical Statistics, 1947 In this article certain contributions are made to the theory of estimating linear functions of cell proportions in connection with the methods of (1) least squares, (2) minimum chi-square, and (3) maximum likelihood. Distinctions among these three methods made by previous writers arise out of (1) confusion concerning theoretical vs. practical weights, (

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic kidney disease is a growing public health problem worldwide, and the number of patients requiring renal replacement therapy is steadily increasing. Türkiye has experienced a similar rise in both the incidence and prevalence of renal replacement therapy over the past decades; however, national‐level projections of future ...

Simulation of the Impact of a Sensor’s PSF on Mixed Pixel Decomposition: 1. Nonuniformity Effect
Remote Sensing, 2016 The nonuniformity of the spatial response to surface radiation is a fundamental characteristic of all airborne and spaceborne sensors that inevitably introduces uncertainty into the estimation of object proportions by the spectral unmixing of mixed ...

, 2016 The application of Partial Membership Latent Dirichlet Allocation(PM-LDA) for hyperspectral endmember estimation and spectral unmixing is presented. PM-LDA provides a model for a hyperspectral image analysis that accounts for spectral variability and ...

Partial likelihood estimation of isotonic proportional hazards models [PDF]
Biometrika, 2017 We consider the estimation of the semiparametric proportional hazards model with an unspecified baseline hazard function where the effect of a continuous covariate is assumed to be monotone. Previous work on nonparametric maximum likelihood estimation for isotonic proportional hazard regression with right-censored data is computationally intensive ...

By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

A simple way of improving the Bar–Lev, Bobovitch and Boukai Randomized response model
Kuwait Journal of Science, 2017 Eichhorn & Hayre (1983) considered a randomized response procedure suitable for estimating the mean response, when the sensitive variable under investigation is quantitative in nature.

Estimating the proportion of neutral mutations [PDF]
New Zealand Journal of Botany, 1993 Abstract A maximum likelihood method is used for the estimation of the proportion of gene mutations that are selectively neutral. Random samples, including both neutral and deleterious alleles, are simulated by computer, and the allele frequencies are determined.
