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 ... -
Manifolds with $4\frac{1}{2}$-Positive Curvature Operator of the Second Kind
(Springer Nature, 2022-08-04)We show that a closed four-manifold with $4\frac{1}{2}$-positive curvature operator of the second kind is diffeomorphic to a spherical space form. The curvature assumption is sharp as both ${\mathbb{CP}\mathbb{}}^2$and ... -
Manifolds with nonnegative curvature operator of the second kind
(World Scientific Publishing Co., 2023-01-13)We investigate the curvature operator of the second kind on Riemannian manifolds and prove several classification results. The first one asserts that a closed Riemannian manifold with three-positive curvature operator of ... -
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 cross section using newly developed reconstruction tool in the NOvA and dune near detector
(Wichita State University, 2023-04-14)The NOvA and DUNE neutrino experiments are designed to study neutrinos and their interaction properties with matter. Neutrinos, the most abundant massive particle in the universe. They are produced inside the sun, supernovae, ... -
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 double-differential muon-neutrino charged-current inclusive cross section in the NOvA near detector
(American Physical Society, 2023-03-27)We report cross-section measurements of the final-state muon kinematics for $ν{_μ}$ charged-current interactions in the NOvA near detector using an accumulated 8.09×10$^{20}$ protons on target in the NuMI beam. We present ... -
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. ... -
Measurement of the ν$_e$-Nucleus Charged-Current Double-Differential Cross Section at ⟨$E$$_ν$⟩=2.4 GeV Using NOvA
(American Physical Society, 2022-11-08)The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using 8.02 ×10$^{20}$ protons-on-target in the NuMI beam. The sample of GeV electron neutrino interactions is the largest ... -
Measurement of ν$_μ$ charged-current inclusive π$^0$ production in the NOvA near detector
(American Physical Society, 2023-06-05)Cross sections for the interaction ν$_μ$ A → μ −π$^0$ X with neutrino energies between 1 and 5 GeV are measured using a sample of 165,000 selected events collected in the NOvA experiment's near detector, a hydrocarbon-based ... -
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 ... -
Modeling the spread of the Coronavirus
(Wichita State University, 2020-05-03)This talk will introduce statistical modeling concepts relating to prediction of COVID rates at a county level and specifically introduce the notion of spatial correlation, which recognizes that there is a connection between ... -
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 ... -
