Hspaces, loop spaces and the space of positive scalar curvature metrics on the sphere
(Mathematical Sciences Publishers, 20141002)For dimensions n >= 3, we show that the space Riem(+)(Sn) of metrics of positive scalar curvature on the sphere Sn is homotopy equivalent to a subspace of itself which takes the form of an Hspace with a homotopy ... 
The HANOHANO Detector and Ongoing Research and Development
(Elsevier, 2012)The Hanohano neutrino detector is a deep sea module that can be submerged to the ocean floor far away from surface radiation. Its Physics goals are the study of geoneutrinos to probe the isotope source of the 45 TW of ... 
Higgs boson Mass in GMSB with Messenger–Matter mixing
(Elsevier, 201212)A Higgslike particle with mass of order 125 GeV has been observed by both ATLAS and CMS experiments. This Higgs mass causes sparticle masses in the several to multiTeV range in the simple version of minimal GMSB models. ... 
Higgs boson of mass 125 GeV in gauge mediated supersymmetry breaking models with mattermessenger mixing
(American Physical Society, 20130905)We investigate the effects of messengermatter mixing on the lightest CPeven Higgs boson mass m(h) in gaugemediated supersymmetry breaking models. It is shown that with such mixings m(h) can be raised to about 125 GeV, ... 
A historical overview of connections in geometry
(Wichita State University, 201105)This thesis is an attempt to untangle/clarify the modern theory of connections in Geometry. Towards this end a historical approach was taken and original as well as secondary sources were used. An overview of the most ... 
Holomorphic functions on subsets of C
(Mathematical Society of Japan, 201301)Let Gamma be a Cinfinity curve in C containing 0; it becomes Gamma(theta) after rotation by angle theta about 0. Suppose a Cinfinity function f can be extended holomorphically to a neighborhood of each element of the ... 
Horizontal bundles and connections
(Wichita State University. Graduate School, 20140425)A manifold is a mathematical space that locally resembles standard Euclidean space. In order to study the geometry of such a space, it is necessary to prescribe a connection on the manifold. A connection describes how ... 
How to lift positive Ricci curvature
(Mathematical Sciences Publishers, 20150521)We show how to lift positive Ricci and almost nonnegative curvatures from an orbit space M / G to the corresponding Gmanifold, M. We apply the results to get new examples of Riemannian manifolds that satisfy both curvature ... 
Hybrid basis scheme for computing electrostatic fields exterior to closetotouching discs
(Oxford University Press, 201604)This paper presents a simple and effective new numerical scheme for the computation of electrostatic fields exterior to a collection of closetotouching discs. The method is presented in detail for the twodisc case. The ... 
Hydrogenation of Carbon Dioxide over CoFe Bimetallic Catalysts
(American Chemical Society, 201602)A series of CoFe bimetallic catalysts was prepared, characterized, and studied for the hydrogenation of carbon dioxide. The catalyst precursors were prepared via an oxalate coprecipitation method. Monometallic (Co or Fe) ... 
Hydrogenation of carbon dioxide over iron carbide prepared from alkali metal promoted iron oxalate
(Elsevier, 20180825)Iron carbide was prepared by the carburization of iron oxalate doped with various alkali metals in flowing CO at 400 degrees C. The addition of alkali metal (Li, Na, K, Rb or Cs) to iron oxalate was found to decrease the ... 
Hydrogenation of carbon dioxide over KPromoted FeCo bimetallic catalysts prepared from mixed metal oxalates
(John Wiley & Sons, Inc., 20170407)The hydrogenation of carbon dioxide over Kpromoted FeCo bimetallic catalysts prepared by sequential oxalate decomposition and carburization of FeCo with CO was studied in a fixedbed reactor at 240 degrees C and 1.2MPa. ... 
Hyperbolic cosine ratio and hyperbolic sine ratio random fields
(Elsevier, 202112)This paper introduces several vector random fields whose finitedimensional characteristic functions are of hyperbolic type, including generalized logistic, hyperbolic secant, hyperbolic tangent, hyperbolic cosine ratio, ... 
Hyperbolic problems
(Springer, 2017)In this chapter, we are interested in finding coefficients of the secondorder hyperbolic operator. 
Hyperbolic vector random fields with hyperbolic direct and cross covariance functions
(Taylor & Francis, 20120626)This article introduces the hyperbolic vector random field whose finitedimensional distributions are the generalized hyperbolic one, which is formulated as a scale mixture of Gaussian random fields and is thus an elliptically ... 
Improved asymptotics of a decreasing mean residual life estimator
(Taylor & Francis Group, 20140917)The mean residual life of a life distribution, X, with a finite mean is defined by M(t) = E[X  tX > t] for t > 0. Kochar etal. (2000) provided an estimator of M when it is assumed to be decreasing. They showed that its ... 
Improvement of the nova near detector event reconstruction and primary vertexing through the application of machine learning methods
(Wichita State University, 202012)The purpose of this work is to examine the application of a deep learning model in event reconstruction of neutrino interactions. The challenges faced in event reconstruction include the placement of an accurate primary ...
