Pairwise Accelerated Failure Time Regression Models for Infectious Disease Transmission in Close‐Contact Groups With External Sources of Infection (2024)
Journal Article
Sharker, Y., Diallo, Z., KhudaBukhsh, W. R., & Kenah, E. (2024). Pairwise Accelerated Failure Time Regression Models for Infectious Disease Transmission in Close‐Contact Groups With External Sources of Infection. Statistics in Medicine, 43(27), 5138-5154. https://doi.org/10.1002/sim.10226

Many important questions in infectious disease epidemiology involve associations between covariates (e.g., age or vaccination status) and infectiousness or susceptibility. Because disease transmission produces dependent outcomes, these questions are...

Modelling the influence of vitamin D and probiotic supplementation on the microbiome and immune response (2024)
Journal Article
Franks, S. J., Dunster, J. L., Carding, S. R., Lord, J. M., Hewison, M., Calder, P. C., & King, J. R. (2024). Modelling the influence of vitamin D and probiotic supplementation on the microbiome and immune response. Mathematical Medicine and Biology, 41(4), 304-345. https://doi.org/10.1093/imammb/dqae017

The intestinal microbiota play a critical role in human health and disease, maintaining metabolic and immune/inflammatory health, synthesizing essential vitamins and amino acids and maintaining intestinal barrier integrity. The aim of this paper is t... Read More about Modelling the influence of vitamin D and probiotic supplementation on the microbiome and immune response.

SIR epidemics in populations with large sub-communities (2024)
Journal Article
Ball, F., Sirl, D., & Trapman, P. (2024). SIR epidemics in populations with large sub-communities. Annals of Applied Probability, 34(5), 4408–4454. https://doi.org/10.1214/24-aap2070

We investigate final outcome properties of an SIR (susceptible → in-fective → recovered) epidemic model defined on a population of large sub-communities in which there is stronger disease transmission within the communities than between them. Our ana... Read More about SIR epidemics in populations with large sub-communities.

HiPhom𝜺: HIgh order Projection-based HOMogenisation for advection diffusion reaction problems (2024)
Journal Article
Conni, G., Piccardo, S., Michele Porta, G., & Icardi, M. (in press). HiPhom𝜺: HIgh order Projection-based HOMogenisation for advection diffusion reaction problems. Multiscale Modeling and Simulation: A SIAM Interdisciplinary Journal,

We propose a new model reduction technique for multiscale scalar transport problems that exhibit dominant axial dynamics. To this aim, we rely on the separation of variables to combine a Hierarchical Model (HiMod) reduction with a two-scale asymptoti...

Stratified distributional analysis—a novel perspective on RT distributions (2024)
Journal Article
Thul, R., Marsh, J., Dijkstra, T., & Conklin, K. (2024). Stratified distributional analysis—a novel perspective on RT distributions. Quarterly Journal of Experimental Psychology, https://doi.org/10.1177/17470218241288516

Abstract
Response times and their distributions serve as a powerful lens into cognitive processes. We present a novel statistical methodology called stratified distributional analysis (SDA) to quantitatively assess how key determinants of response t...

Investigative power of Genomic Informational Field Theory (GIFT) relative to GWAS for genotype-phenotype mapping (2024)
Journal Article
Kyratzi, P., Matika, O., Brassington, A. H., Clare, C. E., Xu, J., Barrett, D. A., Emes, R. D., Archibald, A. L., Paldi, A., Sinclair, K. D., Wattis, J., & Rauch, C. (2024). Investigative power of Genomic Informational Field Theory (GIFT) relative to GWAS for genotype-phenotype mapping. Physiological Genomics, 56(11), 791-806. https://doi.org/10.1152/physiolgenomics.00049.2024

Identifying associations between phenotype and genotype is the fundamental basis of genetic analyses. Inspired by frequentist probability and the work of R.A. Fisher, genome-wide association studies (GWAS) extract information using averages and varia...

Topo-Geometric Analysis of Variability in Point Clouds using Persistence Landscapes (2024)
Journal Article
Matuk, J., Kurtek, S., & Bharath, K. (2024). Topo-Geometric Analysis of Variability in Point Clouds using Persistence Landscapes. IEEE Transactions on Pattern Analysis and Machine Intelligence, 46(12), 11035-11046. https://doi.org/10.1109/TPAMI.2024.3451328

Topological data analysis provides a set of tools to uncover low-dimensional structure in noisy point clouds. Prominent amongst the tools is persistence homology, which summarizes birth-death times of homological features using data objects known as...

Complex-plane singularity dynamics for blow up in a nonlinear heat equation: analysis and computation (2024)
Journal Article
Fasondini, M., King, J. R., & Weideman, J. A. (2024). Complex-plane singularity dynamics for blow up in a nonlinear heat equation: analysis and computation. Nonlinearity, 37(10), Article 105005. https://doi.org/10.1088/1361-6544/ad700b

Blow-up solutions to a heat equation with spatial periodicity and a quadratic nonlinearity are studied through asymptotic analyses and a variety of numerical methods. The focus is on tracking the dynamics of the singularities in the complexified spac...
