NLO multijet merging for Higgs production
(Wichita State University, 20220429)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, 20220813)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 ... 
Nonnegatively curved 6manifolds with almost maximal symmetry rank
(Springer Nature, 201901)We classify closed, simply connected, nonnegatively curved 6manifolds 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, 19920624)The energy decay of a selfexcited wave equation utt  c2 Â¿ u  P(x)ut = 0 is studied where the wave speed c is greater than one, P(x) Â¿ 0, and P(x) LÂ¿(Â¿), Â¿ Â¿ Â¿ Rn. Moreover, the relationship between two bounds for ... 
Numerical computation of a preimage domain for an infinite strip with rectilinear slits
(Springer Link, 20230116)Let Ω be the multiply connected domain in the extended complex plane $\overline {\mathbb {C}}$obtained by removing m nonoverlapping rectilinear segments from the infinite strip $S=\{z : \left \text {Im} z\right <\pi ... 
Numerical computation of SchwarzChristoffel transformations and slit maps for multiply connected domains
(Wichita State University, 201205)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 RiemannHilbert problems in multiply connected circle domains
(Elsevier Science Inc., 20161201)RiemannHilbert 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 RiemannHilbert problems in multiply connected circle domains
(Wichita State University, 202005)RiemannHilbert 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 CauchyRiemann ... 
NuSol neutrino detector prototypes: An analysis of the efficiency and backgrounds of the detectors
(Wichita State University, 202112)The NuSol project aims to orbit a satellite fitted with a galliumdoped 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 multiplemuon events in the NOvA Near Detector
(American Physical Society, 20190628)Using two years of data from the NOvA Near Detector at Fermilab, we report a seasonal variation of cosmic ray induced multiplemuon $(N\mu\ge2)$ event rates which has an opposite phase to the seasonal variation in the ... 
Observational constraints on the origin of the elements
(EDP Sciences, 20220520)Context. The chemical composition of the Sun is required in the context of various studies in astrophysics, among them in the calculation of standard solar models (SSMs) used to describe the evolution of the Sun from the ... 
On an ad hoc test for order restricted multivariate normal means
(Taylor & Francis Group, 2016)For several normal mean vectors restricted by a simple ordering with respect to a multivariate order, this article derives sufficient and necessary conditions for the restricted MLEs for both mean vectors and covariance ... 
On convergence sets of divergent power series
(Polish Academy of Sciences Institute of Mathematics, 2012)A nonlinear generalization of convergence sets of formal power series, in the sense of AbhyankarMoh [J. Reine Angew. Math. 241 (1970)], is introduced. Given a family y = phi(s)(t, x) = sb(1)(x)t + b(2)(x)t(2) + ... of ... 
On convergence sets of formal power series
(Wichita State University, 201312)In this thesis we consider the convergence sets of formal power series of the form f(z, t)=sigma infinity j=0 pj(z)tj, where pj(z) are polynomials. A subset E of the complex plane C is said to be a convergence set if there ... 
On cusp solutions to a prescribed mean curvature equation
(Pacific Journal of Mathematics, 201705)The nonexistence of "cusp solutions" of prescribed mean curvature boundary value problems in Omega x R when Omega is a domain in R2 is proven in certain cases and an application to radial limits at a corner is mentioned. 
On determining sets for holomorphic automorphisms
(Rocky Mountain Mathematics Consortium, 20060114)We study sets K in the closure of a domain D Cn such that, if an automorphism ' of D fixes each point of K, then ' is the identity mapping. A separate result is proved for the case that K lies entirely in the boundary of D.
