Automated detection of over- and under-dispersion in baseline tables in randomised controlled trials. [PDF]
Background: Papers describing the results of a randomised trial should include a baseline table that compares the characteristics of randomised groups. Researchers who fraudulently generate trials often unwittingly create baseline tables that are implausibly similar (under-dispersed) or have large differences between groups (over-dispersed). I aimed to

In Situ Formation of Nanoparticles from Graft Copolypeptides Under Dispersion Polymerization Conditions. [PDF]
Abstract A simple method is presented for preparing polypeptide nanoparticles using hydrophilic biosynthetic ε‐poly(lysine) (εPL) as a reactive surfactant under dispersion polymerization conditions. In situ graft polymerization of benzyl‐L‐glutamic acid N ‐carboxyanhydride ...

A Flexible Multivariate Distribution for Correlated Count Data
Multivariate count data are often modeled via a multivariate Poisson distribution, but it contains an underlying, constraining assumption of data equi-dispersion (where its variance equals its mean).

A Conway–Maxwell–Poisson-Binomial AR(1) Model for Bounded Time Series Data
Binomial autoregressive models are frequently used for modeling bounded time series counts. However, they are not well developed for more complex bounded time series counts of the occurrence of n exchangeable and dependent units, which are becoming ...

Study on Modification of Nano Alumina and Its Enhancement of Physical Properties of Water-Based Acrylic Coatings [PDF]
For enhancing the physical properties of water-based acrylic resin coating, a green modified water-based nano-alumina dispersion was successfully prepared by regulating mass fraction of anti-sedimentation dispersant under the condition of ultrasonication.

Macro‐financial volatility under dispersed information
We provide a production‐based asset pricing model with dispersed information and small deviations from full rational expectations. In the model, aggregate output and equity prices depend on the higher‐order beliefs about aggregate demand and individual stochastic discount factors.

Nano-Structured Materials under Irradiation: Oxide Dispersion-Strengthened Steels
Oxide dispersion-strengthened materials are reinforced by a (Y, Ti, O) nano-oxide dispersion and thus can be considered as nanostructured materials. In this alloy, most of the nanoprecipitates are (Y, Ti, O) nano-oxides exhibiting a Y2Ti2O7 pyrochlore ...

Basic Features of the Analysis of Germination Data with Generalized Linear Mixed Models
Germination data are discrete and binomial. Although analysis of variance (ANOVA) has long been used for the statistical analysis of these data, generalized linear mixed models (GzLMMs) provide a more consistent theoretical framework. GzLMMs are suitable
