Variances of Variance Components: I. Balanced Designs

open access: yesThe Annals of Mathematical Statistics, 1956
1. Summary. Analyses of variance are sometimes intended to reveal information about means (when tests of significance and, better, confidence procedures are appropriate). At other times analyses of variance have the purpose indicated by their name: to estimate the sizes of the various components contributed to the over-all variance from the ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Sequential Tests for Variance Ratios and Components of Variance

open access: yesThe Annals of Mathematical Statistics, 1958
A general sequential sampling method is given for problems of comparing the variances of two or more normal populations in terms of ratios of variances. Sequential tests are given for a hypothesis specifying the ratio of two variances, including tests for variance components in the analysis of variance (Model II).

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

open access: yesFEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

What do the L2 Generalizability Studies Tell Us?

open access: yesAsian Journal of Assessment in Teaching and Learning, 2011
This research synthesis examines the relative magnitudes of the variance components found in 44 generalizability (G) theory studies in L2 testing. I begin by explaining what G theory is and how it works.
