Detecting AI Training in Datacentre Power
Tom Kimpson, Mauricio Baker, Emlyn Graham
AI governance agreements require methods to detect large model training runs on a monitored computing cluster, without trusting the operator. We develop a method to detect synchron…
Can Power Draw Constrain Covert Compute? Limits of Analogue Verification for AI Governance
Tom Kimpson, Mauricio Baker, Emlyn Graham
Frontier AI treaties or agreements on limiting computation require external verification; an external auditor must be able to confirm how much computation actually ran and that par…
Narrow spectral artifact investigation and mitigation in LIGO data from the fourth LIGO-Virgo-KAGRA observing run
E. Goetz, A. Neunzert, A. M. Knee +258
We present efforts to identify, characterize, and mitigate narrow spectral artifacts in LIGO detector data during the fourth LIGO-Virgo-KAGRA observing run. Narrow spectral artifac…
Temporal Memory in Repeating Fast Radio Bursts: Epsilon-Machine Reconstruction of Causal Structure in Burst Timing
Tom Kimpson, Joseph O'Leary
The emission mechanism of fast radio bursts (FRBs) remains unknown. Whether the bursts from a repeating FRB arrive at random or in a structured sequence is a key constraint on that…
Reduced-Precision Stochastic Simulation for Mathematical Biology
Tom Kimpson, Mark B. Flegg, Jennifer A. Flegg
The stochastic simulation algorithm (SSA) is widely used to perform exact forward simulation of discrete stochastic processes in biology. However, the computational cost, driven by…
Search for continuous gravitational waves from neutron stars in five globular clusters in the first part of the fourth LIGO-Virgo-KAGRA observing run
Damon H. T. Cheung, Keith Riles, Rafel Amengual +15
We present the results of directed searches for continuous gravitational waves from unknown neutron stars in five Milky Way globular clusters. We carry out these searches in the LI…
Multiscale Modelling of Birth-Death Processes
Tom Kimpson, Domenic P. J. Germano, Jennifer A. Flegg +1
Many biological systems exhibit multiscale dynamics, where some species occur in high copy numbers while others remain rare. This heterogeneity necessitates hybrid modelling approa…
