Neutrino interaction classification with a convolutional neural network in the DUNE far detector
(American Physical Society, 2020-11-09)The Deep Underground Neutrino Experiment is a next-generation neutrino oscillation experiment that aims to measure CP-violation in the neutrino sector as part of a wider physics program. A deep learning approach based on ... -
New constraints on oscillation parameters from $ν_e$ appearance and $ν_μ$ disappearance in the NOvA experiment
(American Physical Society, 2018-08-24)We present updated results from the NOvA experiment for $\nu_\mu\rightarrow\nu_\mu$ and $\nu_\mu\rightarrow\nu_e$ oscillations from an exposure of $8.85\times10^{20}$ protons on target, which represents an increase of 46% ... -
A new test for decreasing mean residual lifetimes
(Taylor & Francis, 2018-03-02)The mean residual life of a non negative random variable X with a finite mean is defined by M(t) = E[X - t|X > t] for t 0. One model of aging is the decreasing mean residual life (DMRL): M is decreasing (non increasing) ... -
A new test for new better than used in expectation lifetimes
(Taylor & Francis Group, 2015)The mean residual life of a non negative random variable X with a finite mean is defined by M(t) = E[X - t | X > t] for t >= 0. A popular nonparametric model of aging is new better than used in expectation (NBUE), when ... -
Nilsolitons of H-type in the Lorentzian setting
(Houston Journal of Mathematics, 2015)It is known that all left-invariant pseudo-Riemannian metrics on the three-dimensional Heisenberg group H-3 are algebraic Ricci solitons. We consider generalizations of Riemannian H-type, namely pseudoH-type and pH-type. ... -
NLO multijet merging for Higgs production
(Wichita State University, 2022-04-29)The discovery of the Higgs boson in 2012 by ATLAS and CMS Collaborations at the Large Hadron Collider (LHC) opens a new era to particle physics, making processes involving Higgs production interesting and essential in many ... -
NLO multijet merging for Higgs production beyond the VBF approximation
(Springer Nature, 2022-08-13)We present results of the simulation of electroweak Higgs boson production at the Large Hadron Collider using both the NLO multijet merging and NLO matching frameworks provided by the general purpose event generator Herwig ... -
Non-negatively curved 6-manifolds with almost maximal symmetry rank
(Springer Nature, 2019-01)We classify closed, simply connected, non-negatively curved 6-manifolds of almost maximal symmetry rank up to equivariant diffeomorphism. -
Numerical comparison of negative damping bounds in a specified domain when the wave speed varies
(IEEE, 1992-06-24)The energy decay of a self-excited wave equation utt - c2 ¿ u - P(x)ut = 0 is studied where the wave speed c is greater than one, P(x) ¿ 0, and P(x) L¿(¿), ¿ ¿ ¿ Rn. Moreover, the relationship between two bounds for ... -
Numerical computation of a preimage domain for an infinite strip with rectilinear slits
(Springer Link, 2023-01-16)Let Ω be the multiply connected domain in the extended complex plane $\overline {\mathbb {C}}$obtained by removing m non-overlapping rectilinear segments from the infinite strip $S=\{z : \left |\text {Im} z\right |<\pi ... -
Numerical computation of Schwarz-Christoffel transformations and slit maps for multiply connected domains
(Wichita State University, 2012-05)Two methods for the numerical conformal mapping of domains with m < ∞ separated circular holes to domains with m polygonal holes are presented; bounded and unbounded domains are both considered. The methods are based on ... -
Numerical methods for Riemann-Hilbert problems in multiply connected circle domains
(Elsevier Science Inc., 2016-12-01)Riemann-Hilbert problems in multiply connected domains arise in a number of applications, such as the computation of conformal maps. As an example here, we consider a linear problem for computing the conformal map from the ... -
Numerical methods for Riemann-Hilbert problems in multiply connected circle domains
(Wichita State University, 2020-05)Riemann-Hilbert problems are problems for determining functions analytic in a given domain with speci ed values on the boundary. Since the real and imaginary parts of an analytic function are related by the Cauchy-Riemann ... -
NuSol neutrino detector prototypes: An analysis of the efficiency and backgrounds of the detectors
(Wichita State University, 2021-12)The NuSol project aims to orbit a satellite fitted with a gallium-doped scintillator within 10 solar radii of the sun on closest approach. The advantage of the close proximity to the sun is a much higher flux of neutrinos ... -
Observation of seasonal variation of atmospheric multiple-muon events in the NOvA Near Detector
(American Physical Society, 2019-06-28)Using two years of data from the NOvA Near Detector at Fermilab, we report a seasonal variation of cosmic ray induced multiple-muon $(N\mu\ge2)$ event rates which has an opposite phase to the seasonal variation in the ... -
