An introduction to causal inference for pharmacometricians

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 12, Issue 1, Page 27-40, January 2023., 2023
Abstract As formal causal inference begins to play a greater role in disciplines that intersect with pharmacometrics, such as biostatistics, epidemiology, and artificial intelligence/machine learning, pharmacometricians may increasingly benefit from a basic fluency in foundational causal inference concepts.

Codomains for the Cauchy-Riemann and Laplace operators in ℝ2

open access: yesJournal of Function Spaces and Applications, 2008
A codomain for a nonzero constant-coefficient linear partial differential operator P(∂) with fundamental solution E is a space of distributions T for which it is possible to define the convolution E*T and thus solving the equation P(∂)S=T.

A note on Berezin-Toeplitz quantization of the Laplace operator

open access: yesComplex Manifolds, 2015
Given a Hodge manifold, it is introduced a self-adjoint operator on the space of endomorphisms of the global holomorphic sections of the polarization line bundle.

Fast and scalable inference for spatial extreme value models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract The generalized extreme value (GEV) distribution is a popular model for analyzing and forecasting extreme weather data. To increase prediction accuracy, spatial information is often pooled via a latent Gaussian process (GP) on the GEV parameters. Inference for GEV‐GP models is typically carried out using Markov Chain Monte Carlo (MCMC) methods,

Hypergraph Laplace Operators for Chemical Reaction Networks [PDF]

open access: yesAdvances in Mathematics 351 (2019) 870-896, 2018
We generalize the normalized combinatorial Laplace operator for graphs by defining two Laplace operators for hypergraphs that can be useful in the study of chemical reaction networks. We also investigate some properties of their spectra.

Aminosulfonated Graphene as a Catalyst for Efficient Production of Biodiesel from Fatty Acids and Crude Vegetable Oils

open access: yesChemSusChem, EarlyView.
The covalent integration of amino and sulfonate groups on the graphene surface significantly enhances activity in acid‐catalyzed reactions, such as in biodiesel production and dehydration of saccharides. Developing such heterogeneous, recyclable catalysts is vital, as acid catalysis represents one of the most general and versatile strategies in organic
