Synthetic Control Methods for Proportions

open access: yes
Synthetic control methods are extensively utilized in political science for estimating counterfactual outcomes in case studies and difference-in-differences settings, often applied to model counterfactual proportional data. However, the conventional synthetic control methods are designed for univariate outcomes, leading researchers to model ...

Synthesis of group I–III–VI semiconductor quantum dots and its application in food safety testing

open access: yesReviews in Analytical Chemistry, 2022
As a good fluorescent material, most I–III–VI ternary semiconductor quantum dots (QDs) do not contain heavy metal elements such as Cd and Pb and thus have low toxicity. In addition, they also have excellent data performance such as narrow band gap, large
