Simple Random Sampling and Stratified Random Sampling
, 2014 Mathematical statistics has been used in various areas because of its accurate and objective results, and relatively small errors. Using statistics in research involves the collecting of samples, or a set of independent samples representing a whole group.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Stratified Random Sampling for Power Estimation
, 1996 In this paper, we present new statistical sampling techniques for performing power estimation at the circuit level. These techniques first transform the power estimation problem to a survey sampling problem, then apply stratified random sampling to ...

, 1948 This paper gives an account of the results of an investigation into one-dimensional systematic sampling, i.e. the sampling of sequences of quantitative values by the use of sampling points equally spaced along the sequence.

Neutralization of the PTX3/CD44 axis suppresses TGF‐β1 signaling in kidney fibrosis
FEBS Letters, EarlyView.This study investigates how the PTX3/CD44 axis promotes kidney fibrosis by activating TGF‐β1 signaling. We demonstrate that the neutralizing antibody WHC‐001 effectively inhibits this pathway, suppressing myofibroblast activation and partial epithelial–mesenchymal transition (EMT).

A study of stratified sampling in simulation
, 1973 In the simulation of systems, the estimates of the system parameters obtained from the simulation runs are random variables. The precision of the estimates is usually subject to the sampling procedure used. This thesis presents a study of the feasibility

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers
Molecular Oncology, EarlyView.The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

On different estimators of a population mean based on ranked sets [PDF]
A review of results concerning the problem of sampling based on ranked sets is presented. From an infinite or finite population n independent samples of n elements each are drawn.

Molecular Oncology, EarlyView.In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.
