Noisy matrix completion for longitudinal data with subject‐ and time‐specific covariates

Canadian Journal of Statistics, EarlyView.
Abstract In this article, we consider the imputation of missing responses in a longitudinal dataset via matrix completion. We propose a fixed‐effect, longitudinal, low‐rank model that incorporates both subject‐specific and time‐specific covariates. To solve the optimization problem, a two‐step optimization algorithm is proposed, which provides good ...

Small‐Molecule KRAS Inhibitors by Tyrosine Covalent Bond Formation

ChemMedChem, EarlyView.
Small molecules form a covalent bond at KRAS tyrosine and inhibit its activation by guanine exchange factors in biochemical assays and mammalian cells. The development of the KRAS G12C inhibitor sotorasib is a major advance toward drugging KRAS. However, the G12C mutation is only found in about 10% of KRAS‐driven tumors. KRAS possesses several tyrosine

The Zr8O6 Secondary Building Unit and Porphyrin Linker Catalyze Light‐Driven H2 Evolution in Porphyrin‐Based Metal Organic Frameworks

ChemSusChem, EarlyView.
Zr8O6‐based metal–organic frameworks (porous coordination network PCN 221 M, M = 2 H, Zn, Ni, ZnNi) with metalloporphyrin linkers are explored for H2 evolution under 405 nm light emitting diode irradiation. PCN 221 Zn exhibits the highest activity with a turnover number (TON) of 4 via dual charge transfer pathways. Spectroscopy revealed Zn‐TCPP acts as

Upcycling of Waste Poly(ethylene terephthalate) : Ammonolysis Kinetics of Model Bis(2‐hydroxyethyl terephthalate) and Particle Size Effects in Polymeric Substrates

ChemSusChem, Accepted Article.
Upcycling of poly(ethylene terephthalate) (PET) through ammonolysis is pursued. Model studies on bis(2‐hydroxyethyl) terephthalate (BHET) reacting with ammonia in excess ethylene glycol (EG) to form terephthalamide (TPD) are presented. Sequential ester conversion is characterized by the pseudo reaction rate constants of = 1.02±0.09 h‐1 and = 0.44±0.08 ...
