An Improved Precision Calculation of the Contact Term within Chiral Effective Field Theory
Graham Van Goffrier
Neutrinoless double-beta () decay is an as-yet unobserved nuclear process, which stands to provide crucial insights for model-building beyond the Standard Model of particle p…
Geometric statistics with subspace structure preservation for SPD matrices
Cyrus Mostajeran, Nathaël Da Costa, Graham Van Goffrier +1
We present a geometric framework for the processing of SPD-valued data that preserves subspace structures and is based on the efficient computation of extreme generalized eigenvalu…
Differential geometry with extreme eigenvalues in the positive semidefinite cone
Cyrus Mostajeran, Nathaël Da Costa, Graham Van Goffrier +1
Differential geometric approaches to the analysis and processing of data in the form of symmetric positive definite (SPD) matrices have had notable successful applications to numer…
Estimating long-term causal effects from short-term experiments and long-term observational data with unobserved confounding
Graham Van Goffrier, Lucas Maystre, Ciarán Gilligan-Lee
Understanding and quantifying cause and effect is an important problem in many domains. The generally-agreed solution to this problem is to perform a randomised controlled trial. H…
Probing the Mechanism of Neutrinoless Double-Beta Decay in Multiple Isotopes
Matteo Agostini, Frank F. Deppisch, Graham Van Goffrier
A large experimental program is being mounted to search for neutrinoless double-beta decay over the next decade. Multiple experiments using different target isotopes are being prep…
Node-wise monotone barrier coupling law for formation control
Jin Gyu Lee, Cyrus Mostajeran, Graham Van Goffrier
We study a node-wise monotone barrier coupling law, motivated by the synaptic coupling of neural central pattern generators. It is illustrated that this coupling imitates the desir…
Fast Regression of the Tritium Breeding Ratio in Fusion Reactors
Petr Mánek, Graham Van Goffrier, Vignesh Gopakumar +3
The tritium breeding ratio (TBR) is an essential quantity for the design of modern and next-generation D-T fueled nuclear fusion reactors. Representing the ratio between tritium fu…
Target formation on the circle by monotone system design
Cyrus Mostajeran, Jin Gyu Lee, Graham Van Goffrier +1
Positivity and Perron-Frobenius theory provide an elegant framework for the convergence analysis of linear consensus algorithms. Here we consider a generalization of these ideas to…
Least-Informative Priors for Decay Searches
Frank F. Deppisch, Graham Van Goffrier
Bayesian parameter inference techniques require a choice of prior distribution which can strongly impact the statistical conclusions drawn. We discuss the construction of least-inf…
Inductive Geometric Matrix Midranges
Graham W. Van Goffrier, Cyrus Mostajeran, Rodolphe Sepulchre
Covariance data as represented by symmetric positive definite (SPD) matrices are ubiquitous throughout technical study as efficient descriptors of interdependent systems. Euclidean…
Visualization of Open and Closed String Worldsheets. Part I: Software Development
Graham W. Van Goffrier, Neil F. Comins
In bosonic string theory, the solutions to the string equations of motion may be expressed as two-dimensional manifolds in a relativistic spacetime. We develop MATLAB software for…
