Sequentially Palladium-Catalyzed Processes in One-Pot Syntheses of Heterocycles
Applied Sciences, 2015 Sequentially Pd-catalyzed processes are excellent entries to heterocycle synthesis. The broad mechanistic variety combined with often very mild reaction conditions allow the concatenation of elementary organic and organometallic steps to novel sequences ...

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

Synthetic versus biological mesh-related erosion after laparoscopic ventral mesh rectopexy. A systematic review [PDF]
, 2017 Purpose: This review reports the incidence of mesh-related erosion after ventral mesh rectopexy to determine whether any difference exists in the erosion rate between synthetic and biological mesh. Methods: A systematic search of the MEDLINE and the Ovid

An Exact and Robust Conformal Inference Method for Counterfactual and Synthetic Controls
, 2020 We introduce new inference procedures for counterfactual and synthetic control methods for policy evaluation. We recast the causal inference problem as a counterfactual prediction and a structural breaks testing problem.

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.
