Simultaneous Photoactivation of Copper and Ti‐Doped CeO2−x Enables Optimal Acceleration of the RWGS Reaction

open access: yesCarbon Energy, EarlyView.
A combination of visible light and thermal energy accelerates the CO formation rate up to 57 times compared to dark conditions using a 3Cu/CeTiO2−x catalyst. Kinetic analysis, as well as steady state and transient spectroscopy, was applied under photocatalytic conditions to analyze and disentangle the reaction channels under dark and illuminated ...

Rank‐based estimation of propensity score weights via subclassification

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Propensity score (PS) weighting estimators are widely used for causal effect estimation and enjoy desirable theoretical properties, such as consistency and potential efficiency under correct model specification. However, their performance can degrade in practice due to sensitivity to PS model misspecification.

Partial identification with categorical data and nonignorable missing outcomes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Nonignorable missing outcomes are common in real‐world datasets and often require strong parametric assumptions to achieve identification. These assumptions can be implausible or untestable, and so we may wish to forgo them in favour of partially identified models that narrow the set of a priori possible values to an identification region.

Serious Infection in Crohn's Disease Patients Treated With Ustekinumab: US Food and Drug Administration Active Postmarket Risk Identification and Analysis in the Sentinel Initiative

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
The U.S. Food and Drug Administration (FDA) used an Active Postmarket Risk Identification and Analysis (ARIA) system to address a safety issue (serious infection) identified during clinical review of an application to market ustekinumab as a treatment for Crohn's disease (CD). FDA used an active‐comparator new‐user cohort design, data from six Sentinel
