Time varying isotropic vector random fields on sphere
(Springer, 201712)For a vector random field that is isotropic and mean square continuous on a sphere and stationary on a temporal domain, this paper derives a general form of its covariance matrix function and provides a series representation ... 
Constraints on the distance moduli, helium, and metal abundances, and ages of globular clusters from their RR Lyrae and nonvariable horizontal branch stars. II. multiple stellar populations in 47 Tuc, M3, and M13
(IOP Publishing, 20171110)We present a new set of horizontal branch (HB) models computed with the MESA stellar evolution code. The models adopt alphaenhanced Asplund et al. metal mixtures and include the gravitational settling of He. They are used ... 
Search for activesterile neutrino mixing using neutralcurrent interactions in NOvA
(American Physical Society, 20171030)We report results from the first search for sterile neutrinos mixing with active neutrinos through a reduction in the rate of neutralcurrent interactions over a baseline of 810 km between the NOvA detectors. Analyzing a ... 
Binomialchi(2) vector random fields
(SIAM Publ., 2017)We introduce a new class of nonGaussian vector random fields in space and/or time, which are termed binomialchi(2) vector random fields and include chi(2) vector random fields as special cases. We define a binomialchi(2) ... 
Vector stochastic processes with PolyaType correlation structure
(Wiley, 201708)This paper introduces a simple method to construct a stationary process on the real line with a Polyatype covariance function and with any infinitely divisible marginal distribution, by randomising the timescale of the ... 
Orientation and symmetries of Alexandrov spaces with applications in positive curvature
(Springer, 201704)We develop two new tools for use in Alexandrov geometry: a theory of ramified orientable double covers and a particularly useful version of the Slice Theorem for actions of compact Lie groups. These tools are applied to ... 
Learning quantum annealing
(Rinton Press, Inc., 20170501)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 twoqubit system, then demonstrate ... 
Constraints on oscillation parameters from nu(e) appearance and nu(mu) disappearance in NOvA
(American Physical Society, 20170605)Results are reported from an improved measurement of nu(mu) > nu(e) transitions by the NOvA experiment. Using an exposure equivalent to 6.05 x 10(20) protons on target, 33 nu(e) candidates are observed with a background ... 
Prediction of land market value based on the real estate market in USA
(Wichita State University, 20170428)The Land Market Value, defined as the total value of land and quantity data are derived from data on housing values, is an important factor in the estimation of structure costs using price indexes for housing and construction ... 
Unexpected radial limit
(Wichita State University, 20170428)Consider a bounded solution ƒ of the prescribed mean curvature equation over a bounded domain Ω ⊂ R² which has a corner at which has a corner at (0, 0) of size 2α and assume the mean curvature of the graph of ƒ is bounded. ... 
Measurement of the neutrino mixing angle theta(23) in NOvA
(American Physical Society, 20170410)This Letter reports new results on muon neutrino disappearance from NOvA, using a 14 kton detector equivalent exposure of 6.05 x 10(20) protons on target from the NuMI beam at the Fermi National Accelerator Laboratory. The ... 
Radial limits of capillary surfaces at corners
(Pacific Journal of Mathematics, 201705)Consider a solution f is an element of C2(Omega) of a prescribed mean curvature equation div del f/root 1+vertical bar del f vertical bar(2) = 2H (x, f) in Omega subset of R2, where Omega is a domain whose boundary ... 
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. 
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. ... 
Estimation of a starshaped distribution function
(Taylor & Francis LTD, 2017)A life distribution function (DF) F is said to be starshaped if F(x)/x is nondecreasing on its support. This generalises the model of a convex DF, even allowing for jumps. The nonparametric maximum likelihood estimation ... 
A comparison of some numerical conformal mapping methods for simply and multiply connected domains
(Wichita State University, 201605)This dissertation compares several methods for computing conformal maps from simply and multiply connected domains bounded by circles to target domains bounded by smooth curves and curves with corners. We discuss the use ... 
Ages of 70 dwarfs of three populations in the solar neighborhood: considering O and C abundances in stellar models
(IOP Publishing Ltd, 20161215)Oxygen and carbon are important elements in stellar populations. Their behavior refers to the formation history of the stellar populations. C and O abundances would also obviously influence stellar opacities and the overall ... 
Recovery of timedependent volatility in option pricing model
(IOP Publishing Ltd, 20160929)In this paper we investigate an inverse problem of determining the timedependent volatility from observed market prices of options with different strikes. Due to the non linearity and sparsity of observations, an analytical ... 
Isotonic regression through the Merge and Chop Algorithm for application in statistical inference
