A Recommendation for Net Undercount Estimation in Iran Population and Dwelling Censuses [PDF]

open access: yesJ. Statist. Res. Iran (2011): 8, 229-251, 2019
Census counts are subject to different types of nonsampling errors. One of these main errors is coverage error. Undercount and overcount are two types of coverage error. Undercount usually occurs more than the other, thus net undercount estimation is important. There are various methods for estimating the coverage error in censuses.

Superchaotropic Nano‐ion Binding as a Gelation Motif in Cellulose Ether Solutions

open access: yesAngewandte Chemie International Edition, Volume 62, Issue 3, January 16, 2023., 2023
Nano‐ions, like polyoxometalates and boron clusters, co‐assemble strongly with non‐ionic solutes in water driven by the chaotropic effect. Here, nano‐ion assembly with non‐ionic cellulose ethers (CE) is shown to result in unprecedented thickening effects and gelation of CE‐solutions. An interplay of electrostatic repulsion and attraction between chains
