Comparison of the Coating Structure of Silicon‐Based PECVD Coatings With Varying Organic Content

Plasma Processes and Polymers, EarlyView.
Silicon‐based PECVD coatings transition abruptly from organic SiOCH to oxidic SiOx at ~32 at% silicon, exhibiting threshold behavior in barrier performance. Chemical composition seems to dominate over porosity: SiOx coatings unexpectedly show higher porosity yet superior barrier properties, possibly due to rigid cage‐like molecular structures ...

Development of a physiologically‐based pharmacokinetic model for Ritonavir characterizing exposure and drug interaction potential at both acute and steady‐state conditions

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 523-539, March 2025.
Abstract Ritonavir (RTV) is a potent CYP3A inhibitor that is widely used as a pharmacokinetic (PK) enhancer to increase exposure to select protease inhibitors. However, as a strong and complex perpetrator of CYP3A interactions, RTV can also enhance the exposure of other co‐administered CYP3A substrates, potentially causing toxicity.

Levenberg-Marquardt method with singular scaling and applications

Applied Mathematics and Computation
Inspired by certain regularization techniques for linear inverse problems, in this work we investigate the convergence properties of the Levenberg-Marquardt method using singular scaling matrices. Under a completeness condition, we show that the method is well-defined and establish its local quadratic convergence under an error bound assumption.

Engineered Gravel Trench Hyporheic Exchange to Create Cold‐Water Thermal Refuges

River Research and Applications, EarlyView.
ABSTRACT Warming rivers are driving a loss or fragmentation of cold‐water habitat and providing the impetus to develop proactive thermal management approaches to maintain suitable habitat in rivers. One innovative approach is through the creation of cold‐water thermal refuges during periods of thermal stress for aquatic species.
