The effectiveness of remediating mathematical Common Student Errors in e-Assessments (2021)
Presentation / Conference
Sikurajapathi, I., Henderson, K., & Gwynllyw, . R. (2021, June). The effectiveness of remediating mathematical Common Student Errors in e-Assessments. Presented at E-Assessment in Mathematical Sciences (EAMS2021), Online

The Common Student Errors Project (CSE Project) has been running at the University of the West of England (UWE, Bristol) since 2017. The main aim of this project is to introduce a method to detect CSEs and to provide tailored feedback in Engineering...

Exact solutions and equi-dosing regimen regions for multi-dose pharmacokinetics models with transit compartments (2020)
Journal Article
Hof, F., & Bridge, L. J. (2021). Exact solutions and equi-dosing regimen regions for multi-dose pharmacokinetics models with transit compartments. Journal of Pharmacokinetics and Pharmacodynamics, 48, 99-131. https://doi.org/10.1007/s10928-020-09719-8

Compartmental models which yield linear ordinary differential equations (ODEs) provide common tools for pharmacokinetics (PK) analysis, with exact solutions for drug levels or concentrations readily obtainable for low-dimensional compartment models....

A blow-up dichotomy for semilinear fractional heat equations (2020)
Journal Article
Laister, R., & Sierżęga, M. (in press). A blow-up dichotomy for semilinear fractional heat equations. Mathematische Annalen, https://doi.org/10.1007/s00208-020-02078-2

We derive a blow-up dichotomy for positive solutions of fractional semilinear heat equations on the whole space. That is, within a certain class of convex source terms, we establish a necessary and sufficient condition on the source for all positive...

Analyzing kinetic signaling data for G-protein-coupled receptors (2020)
Journal Article
Hoare, S. R. J., Tewson, P. H., Quinn, A. M., Hughes, T. E., & Bridge, L. J. (2020). Analyzing kinetic signaling data for G-protein-coupled receptors. Scientific Reports, 10, https://doi.org/10.1038/s41598-020-67844-3

In classical pharmacology, bioassay data are fit to general equations (e.g. the dose response equation) to determine empirical drug parameters (e.g. EC50 and Emax), which are then used to calculate chemical parameters such as affinity and efficacy. H... Read More about Analyzing kinetic signaling data for G-protein-coupled receptors.

Security properties of light clients on the ethereum blockchain (2020)
Journal Article
Paavolainen, S., & Carr, C. (2020). Security properties of light clients on the ethereum blockchain. IEEE Access, 8, 124339-124358. https://doi.org/10.1109/access.2020.3006113

Ethereum is a decentralized blockchain, known as being the second most popular public blockchain after Bitcoin. Since Ethereum is decentralised the canonical state is determined by the Ethereum network participants via a consensus mechanism without a...

10 is the safest number that there’s ever been (2019)
Presentation / Conference
Ritchie, F. (2019, October). 10 is the safest number that there’s ever been. Paper presented at Workshop on statistical data confidentiality 2019, The Hague

When checking frequency and magnitude tables for disclosure risk, the cell threshold (the minimum number of observations in each cell) is the crucial statistic. In rules-based environments, this is a hard limit on what can or can’t be published. In p... Read More about 10 is the safest number that there’s ever been.

User-focused threat identification for anonymised microdata (2019)
Journal Article
Ritchie, F., Hafner, H., & Lenz, R. (2019). User-focused threat identification for anonymised microdata. Statistical Journal of the IAOS, 35(4), 703-713. https://doi.org/10.3233/SJI-190506

© 2019 - IOS Press and the authors. When producing anonymised microdata for research, national statistics institutes (NSIs) identify a number of 'risk scenarios' of how intruders might seek to attack a confidential dataset. This approach has been cri... Read More about User-focused threat identification for anonymised microdata.
