Inferring state‐dependent diversification rates using approximate Bayesian computation
Methods in Ecology and Evolution, EarlyView.Abstract State‐dependent speciation and extinction (SSE) models are a popular framework for quantifying whether species traits have an impact on evolutionary rates and how this shapes the variation in species richness among clades in a phylogeny.

Iterative Approximate Solutions of Kinetic Equations for Reversible Enzyme Reactions [PDF]
, 2013 We study kinetic models of reversible enzyme reactions and compare two techniques for analytic approximate solutions of the model. Analytic approximate solutions of non-linear reaction equations for reversible enzyme reactions are calculated using the ...

, 2009 We propose an algorithmic procedure i) to study the ``distance'' between an integrable PDE and any discretization of it, in the small lattice spacing epsilon regime, and, at the same time, ii) to test the (asymptotic) integrability properties of such ...

Methods in Ecology and Evolution, EarlyView.Abstract Accurate and reliable estimation of wildlife population density is fundamental to effective conservation and management. While camera traps show potential for monitoring ground‐dwelling mammal densities, labour‐intensive data processing remains a significant constraint. Ideally, conservation efforts would benefit from the continuous monitoring

Household food expenditures in the United States: A Bayesian MCMC approach to censored equation systems [PDF]
We apply a Bayesian Markov Chain Monte Carlo (MCMC) technique, along with data augmentation to accommodate censoring in the dependent variables, to the estimation of a large expenditure system of food expenditures.

Rationality problem for algebraic tori
, 2017 We give the complete stably rational classification of algebraic tori of dimensions $4$ and $5$ over a field $k$. In particular, the stably rational classification of norm one tori whose Chevalley modules are of rank $4$ and $5$ is given.

British Journal of Mathematical and Statistical Psychology, EarlyView.Abstract Hidden Markov diagnostic classification models capture how students' cognitive attributes evolve over time. This paper introduces a Bayesian Markov chain Monte Carlo algorithm for diagnostic classification models that jointly estimates time‐varying Q matrices, latent attributes, item parameters, attribute class proportions and transition ...

Is economics self‐correcting? Replications in the American Economic Review
Economic Inquiry, Volume 63, Issue 2, Page 463-485, April 2025.Abstract This paper reviews the impact of replications published as comments in the American Economic Review between 2010 and 2020. We examine their citations and influence on the original papers' (OPs) subsequent citations. Our results show that comments are barely cited, and they do not affect the OP's citations—even if the comment diagnoses ...
