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

Reviews 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

The Augmented Synthetic Control Method [PDF]

Journal of the American Statistical Association, 2021
The synthetic control method (SCM) is a popular approach for estimating the impact of a treatment on a single unit in panel data settings. The synthetic control is a weighted average of control units that balances the treated unit s pretreatment outcomes and other covariates as closely as possible. A critical feature of the original proposal is

Prediction Intervals for Synthetic Control Methods [PDF]

Journal of the American Statistical Association, 2021
Uncertainty quantification is a fundamental problem in the analysis and interpretation of synthetic control (SC) methods. We develop conditional prediction intervals in the SC framework, and provide conditions under which these intervals offer finite-sample probability guarantees. Our method allows for covariate adjustment and non-stationary data.
