Remling’s theorem on canonical systems

open access: yesJournal of Mathematical Physics, 2016
In this paper, we extend the Remling’s theorem on canonical systems that the ω limit points of the Hamiltonian under the shift map are reflectionless on the support of the absolutely continuous part of the spectral measure of a canonical system.

A comparative study of estimators in multilevel linear models.

open access: yesPLoS ONE, 2021
Multilevel Models are widely used in organizational research, educational research, epidemiology, psychology, biology and medical fields. In this paper, we recommend the situations where Bootstrap procedures through Minimum Norm Quadratic Unbiased ...

Characteristic comparison of triglyceride-rich remnant lipoprotein measurement between a new homogenous assay (RemL-C) and a conventional immunoseparation method (RLP-C)

open access: yesLipids in Health and Disease, 2008
Background Increased serum remnant lipoproteins are supposed to predict cardiovascular disease in addition to increased LDL. A new homogenous assay for remnant lipoprotein-cholesterol (RemL-C) has been developed as an alternative to remnant-like particle-

Evaluating the performance of Bayesian and restricted maximum likelihood estimation for stepped wedge cluster randomized trials with a small number of clusters

open access: yesBMC Medical Research Methodology, 2022
Background Stepped wedge trials are an appealing and potentially powerful cluster randomized trial design. However, they are frequently implemented with a small number of clusters.

The analysis of very small samples of repeated measurements II: a modified box correction [PDF]

open access: yes, 2010
There is a need for appropriate methods for the analysis of very small samples of continuous repeated measurements. A key feature of such analyses is the role played by the covariance matrix of the repeated observations.

Row-col method associated with frequentist and Bayesian statistics in a passion fruit population

open access: yesCrop Breeding and Applied Biotechnology, 2023
This study was conducted to test the significance of adding row and column factors in the frequentist and Bayesian models used in the evaluation of a population of Passiflora edulis, as well as selecting promising genotypes to form the next generation ...

Likelihood inference for small variance components

open access: yes, 2000
In this paper, we develop likelihood-based methods for making inferences about the components of variance in a general normal mixed linear model. In particular, we use local asymptotic approximations to construct confidence intervals for the components ...

Sophisticated sperm allocation in male fowl [PDF]

open access: yes, 2003
When a female is sexually promiscuous, the ejaculates of different males compete for the fertilization of her eggs; the more sperm a male inseminates into a female, the more likely he is to fertilize her eggs.

Strategies for multi-trait selection of sweet sorghum progenies

open access: yesCrop Breeding and Applied Biotechnology, 2021
The selection of sweet sorghum genotypes is based on multiple agronomical and technological traits. The objectives of this study were to evaluate the effectiveness of inter-trait recovery information in improving the selective accuracy of the predicted ...
