Learning quantum annealing
(Rinton Press, Inc., 2017-05-01)We propose and develop a new procedure, whereby a quantum system can learn to anneal to a desired ground state. We demonstrate successful learning to produce an entangled state for a two-qubit system, then demonstrate ... -
Linear stability of Hill's vortex to axisymmetric perturbations
(Cambridge University Press, 2016-07)We consider the linear stability of Hill's vortex with respect to axisymmetric perturbations. Given that Hill's vortex is a solution of a free-boundary problem, this stability analysis is performed by applying methods of ... -
A linearised inverse conductivity problem for the Maxwell system at a high frequency
(Elsevier, 2022-04-15)We consider a linearised inverse conductivity problem for electromagnetic waves in a three dimensional bounded domain at a high time-harmonic frequency. Increasing stability bounds for the conductivity coefficient in the ... -
Linearized inverse Schrödinger potential problem at a large wavenumber
(Society for Industrial and Applied Mathematics Publications, 2020)We investigate recovery of the (Schrodinger) potential function from many boundary measurements at a large wavenumber. By considering such a linearized form, we obtain a Holder type stability which is a big improvement ... -
Lipschitz stability in the lateral Cauchy problem for elasticity system
(Kyoto University, 2003-08-01)We consider the isotropic elasticity system: ρ∂2 t u − μ(Δu + ∇(∇Tu))−∇(λ∇Tu) − 3 X j=1 ∇μ · (∇uj + ∂ju)ej = 0 in Ω× (0, T) for the displacement vector u = (u1, u2, u3) depending on x ∈ Ω and t ∈ (0, T) where Ω ... -
Logistic vector random fields with logistic direct and cross covariances
(Elsevier B.V., 2015-06)The logistic vector random field is introduced in this paper as a scale mixture of Gaussian vector random fields, and is thus a particular elliptically contoured (spherically invariant) vector random field. Such a logistic ... -
Long-baseline neutrino oscillation physics potential of the DUNE experiment: DUNE Collaboration
(Springer, 2020-10-22)The sensitivity of the Deep Underground Neutrino Experiment (DUNE) to neutrino oscillation is determined, based on a full simulation, reconstruction, and event selection of the far detector and a full simulation and ... -
Low exposure long-baseline neutrino oscillation sensitivity of the DUNE experiment
(American Physical Society, 2022-04-25)The Deep Underground Neutrino Experiment (DUNE) will produce world-leading neutrino oscillation measurements over the lifetime of the experiment. In this work, we explore DUNE’s sensitivity to observe charge-parity violation ... -
Machine learning applied to programming quantum computers
(American Institute of Aeronautics and Astronautics, 2019-01-06)We apply machine learning to “program” quantum computers, both in simulation and in experimental hardware. A major difficulty in quantum computing is developing effective algorithms that can be programmed on a quantum ... -
Machine learning in NO$\nu$A near detector vertexing
(Wichita State University, 2022-05)This work presents an alternative method for a reconstruction machine learning algorithm in place of the one currently used by the NO$\nu$A (NuMI Off-axis $\nu_e$ Appearance) group for the analysis of neutrino events at ... -
Matched-pairs tests of homogeneity with applications to homologous nucleotide sequences
(Oxford University Press, 2006-05-15)Motivation: Most phylogenetic methods assume that the sequences of nucleotides or amino acids have evolved under stationary, reversible and homogeneous conditions. When these assumptions are violated by the data, there ... -
Measurement of charged pion production yields off the NuMI target
(American Physical Society, 2014-09)The fixed-target Main Injector Particle Production (MIPP) experiment, Fermilab E907, was designed to measure the production of hadrons from the collisions of hadrons of momenta ranging from 5 to 120 GeV/c on a variety of ... -
Measurement of neutrino-induced neutral-current coherent $π^0$ production in the NOvA near detector
(American Physical Society, 2020-07-09)The cross section of neutrino-induced neutral-current coherent $\pi^0$ production on a carbon-dominated target is measured in the NOvA near detector. This measurement uses a narrow-band neutrino beam with an average neutrino ... -
Measurement of the neutrino mixing angle $θ_{23}$ in NOvA
(American Physical Society, 2017-04-10)This Letter reports new results on muon neutrino disappearance from NOvA, using a 14 kton detector equivalent exposure of $6.05\times10^{20}$ protons-on-target from the NuMI beam at the Fermi National Accelerator Laboratory. ... -
Metrics of positive scalar curvature and generalised Morse functions, part II
(American Mathematical Society, 2014-01)The surgery technique of Gromov and Lawson may be used to construct families of positive scalar curvature metrics which are parameterised by Morse functions. This has played an important role in the study of the space of ... -
Mittag-Leffler vector random fields with Mittag-Leffler direct and cross covariance functions
(Springer Heidelberg, 2013-10)In terms of the two-parameter Mittag-Leffler function with specified parameters, this paper introduces the Mittag-Leffler vector random field through its finite-dimensional characteristic functions, which is essentially ... -
Models for inviscid wakes past a normal plate
(Cambridge University Press, 2012-10-10)Closed and open hollow wakes are considered as analytic models for the two-dimensional inviscid steady flow past a plate normal to the stream. It is shown that only open configurations which satisfy the Kutta condition ... -
Models for metal-poor stars with enhanced abundances of C, N, O, Ne, Na, Mg, Si, S, Ca, and Ti, in turn, at constant helium and iron abundances
(IOP Publishing, 2012-08-10)Recent work has shown that most globular clusters have at least two chemically distinct components, as well as cluster-to-cluster differences in the mean [O/Fe], [Mg/Fe], and [Si/Fe] ratios at similar [Fe/H] values. In ... -
Models of metal-poor stars with different initial abundances of C, N, O, Mg, and Si. I. Bolometric corrections derived from new MARCS synthetic spectra and their implications for observed colour-magnitude diagrams
(Oxford University Press, 2021-11-04)New, high-resolution MARCS synthetic spectra have been calculated for more than a dozen mixtures of the metals allowing, in turn, for variations in C:N:O, [CNO/Fe], and enhanced abundances of C, O, Mg, and Si. Bolometric ... -
Models of parenting and its effect on academic productivity: Preliminary results from an international survey
(International Conference on Scientometrics and Informetrics, 2019-09)This preliminary paper investigates the cost of parenting engagement on academic productivity and impact. Instead of investigating the relationship between gender and academia, this study focuses on time invested in parenting ...
