Hierarchical Fluorinated Polymer Separator Design Mitigating Bilateral Ionic Crosstalk in Aqueous Batteries

open access: yesAdvanced Energy Materials, EarlyView.
Aqueous zinc‐ion batteries suffer from rapid decay under practical conditions due to bilateral Zn2+/Mn2+ ionic crosstalk, a system‐level failure mechanism. We develop a hierarchical fluorinated polymer separator that regulates ion fluxes and stabilizes both electrodes simultaneously. This strategy enables extended cycle life while maintaining capacity,

Language Dynamics in Finite Populations

Journal of Theoretical Biology, 2003
Any mechanism of language acquisition can only learn a restricted set of grammars. The human brain contains a mechanism for language acquisition which can learn a restricted set of grammars. The theory of this restricted set is universal grammar (UG). UG has to be sufficiently specific to induce linguistic coherence in a population.

Markov sampling for finite populations

Biometrika, 1992
Summary: We have introduced a new sampling scheme for a finite population, called a Markov sampling scheme, which always provides distinct units for a fixed sample size. The utility of this sampling over conventional simple random sampling and systematic sampling is discussed for certain categories of labelled populations.

A "Super-Population Viewpoint" for Finite Population Sampling

Biometrics, 1975
Frequently it is reasonable for a sample surveyor to view the finite population of interest as an independent sample of size N from an infinite super-population. This super-population viewpoint is contrasted to the classical frequentist theory of finite population sampling and the classical theory of infinite population sampling.

Finite populations; foundation for inference?

Communications in Statistics, 1973
The theme of this paper is the extent to which the assumptions of the general linear hypothesis are justified by purposeful random sampling from a finite population. For three elementary models it is found that the square of the sample size divided by the population size must approach zero to insure substantial agreement between the two approaches ...
