Evaluating the impact of curfews and other measures on SARS-CoV-2 transmission in French Guiana

open access: yesNature Communications, 2021
Identifying effective combinations of control measures in different populations is important for SARS-CoV-2 control. Here, the authors show that in French Guiana, which has a relatively young population, curfews and localised lockdowns appeared to ...

A low-cost wireless sensor network for long term monitoring of energy performance and sustainability of buildings [PDF]

open access: yesMATEC Web of Conferences, 2019
This manuscript describes the development of a wireless sensor system for long term monitoring of temperature, humidity and heat flux reading within building structural elements, including places that are hard to reach using wired sensors. The system was

Hyper Coupled Map Lattices for Hiding Multiple Images

open access: yesComplexity, 2023
The concept of a hyper coupled map lattice (CML) is presented in this paper. The complexity of the lattice is increased not by adding another spatial dimension of the lattice but by replacing scalar nodal variables by multidimensional square matrices of ...

Conceptual modelling: Towards detecting modelling errors in engineering applications [PDF]

open access: yes, 2019
Rapid advancements of modern technologies put high demands on mathematical modelling of engineering systems. Typically, systems are no longer “simple” objects, but rather coupled systems involving multiphysics phenomena, the modelling of which involves ...

A comprehensive overview of genomic imprinting in breast and its deregulation in cancer

open access: yesNature Communications, 2018
In growth and development genomic imprinting is important in regulating gene expression. Here, the authors study loss of imprinting (LOI) in cancer, developing a mixture model to detect monoallelically expressed loci without genotyping data - applying ...

Modelling the medium-term dynamics of SARS-CoV-2 transmission in England in the Omicron era

open access: yesNature Communications, 2022
This mathematical modelling study projects the dynamics of SARS-CoV-2 in England until the end of 2022 assuming that the Omicron BA.2 sublineage remains dominant.

Assessing the effects of non-pharmaceutical interventions on SARS-CoV-2 transmission in Belgium by means of an extended SEIQRD model and public mobility data

open access: yesEpidemics, 2021
We present a compartmental extended SEIQRD metapopulation model for SARS-CoV-2 spread in Belgium. We demonstrate the robustness of the calibration procedure by calibrating the model using incrementally larger datasets and dissect the model results by ...
