Predicting rare events using training data from stratified sampling designs, with application to human‐caused wildfire prediction

Canadian Journal of Statistics, EarlyView.
Abstract Response‐based sampling is often used in modelling rare events from large, imbalanced data for efficiency. When modelling the event with logistic regression, the sampling design may be adjusted for using sampling weights or an offset. We propose a stratified sampling design for modelling rare events with large data which improves on previous ...

Exploring Bonding in Bioinorganic Chemistry: Ab Initio Valence Bond Calculations of Iron(II)‐CO and Iron(IV)‐Oxo Units in Cytochrome P450 under Oriented External Electric Fields

Chemistry–Methods, EarlyView.
Ab initio valence bond calculations under oriented electric fields along the bond axis of Fe(II)‐CO and Fe(IV)‐oxo units in cytochrome P450 enzymes highlight their effectiveness in probing complex bonding characteristics and ligand effects in bioinorganic systems.

The porous medium equation: Large deviations and gradient flow with degenerate and unbounded diffusion

Communications on Pure and Applied Mathematics, EarlyView.
Abstract The problem of deriving a gradient flow structure for the porous medium equation which is thermodynamic, in that it arises from the large deviations of some microscopic particle system is studied. To this end, a rescaled zero‐range process with jump rate g(k)=kα,α>1$g(k)=k^\alpha, \alpha >1$ is considered, and its hydrodynamic limit and ...

Linear and Two‐Dimensional Infrared Spectroscopy of the Multifunctional Vibrational Probe, 3‐(4‐Azidophenyl) Propiolonitrile. Deperturbing a Fermi Triad by Isotopic Substitution

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Linear infrared spectroscopy combined with isotope labeling and density functional theory unravels the origin of a Fermi triad in a multifunctional vibrational chromophore. Ultrafast 2DIR‐spectroscopy reports directly on the dynamics and the intramolecular vibrational energy flow pathways in the isotopically deperturbed system. Abstract Infrared probes
