Ages of mainsequence turnoff stars from the GALAH survey
(American Astronomical Society, 20220401)Mainsequence turnoff (MSTO) stars are good tracers of Galactic populations since their ages can be reliably estimated from atmospheric parameters. Based on the GALAH survey, we use the Yale rotation evolution code to ... 
Algorithm for determining the volatility function in the Black–Scholes model
(Pleiades Publishing, 201910)Abstract: An algorithm for reconstructing the volatility function in the modified Black–Scholes model is developed. Results of numerical computations are presented. It is shown that adding information about the prices of ... 
Almost nonnegatively curved 4manifolds with torus symmetry
(American Mathematical Society, 20200814)We prove that if a closed, smooth, simplyconnected 4manifold with a circle action admits an almost nonnegatively curved sequence of invariant Riemannian metrics, then it also admits a nonnegatively curved Riemannian ... 
An adaptive multiresolution ultraweak discontinuous Galerkin method for nonlinear Schrödinger equations
(Springer Link, 20210125)This paper develops a highorder adaptive scheme for solving nonlinear Schrödinger equations. The solutions to such equations often exhibit solitary wave and local structures, which make adaptivity essential in improving ... 
An analysis of the replies to the Kansas American Association of University Women's questionnaire on teacher welfare
(Wichita State University, 194805) 
An opensource implementation of the quick CSF method for rapid evaluation of contrast sensitivity
(Wichita State University, 20190426)Contrast sensitivity is an important feature of functional vision, but traditional psychometric assessment methods require an excessive number of trials to estimate a complete contrast sensitivity function across the full ... 
Annular capillary surfaces
(BirkhäuserVerlag, Basel, 20040501)The meniscus in a symmetric annular capillary tube is investigated. The contact angles on the inner and outer tube surface need not be the same. Existence and qualitative properties of solutions are obtained using an ... 
Application of the limit of truncated isotonic regression in optimization subject to isotonic and bounding constraints
(Academic Press Inc., 20020525)An isotonic regression truncated by confining its domain to a union of its level sets is the isotonic regression in the reduced function space. When some of the weights with which the inner product system is defined go to ... 
Applications of the hCobordism Theorem
(Wichita State University, 201405)We provide an exposition of J. Milnor's proof of the hCobordism Theorem. This theorem states that a smooth, compact, simply connected ndimensional manifold W with n greater than or equal to 6, whose boundary boundaryW ... 
Applied topological data analysis to ElNiño Southern Oscillation
(Wichita State University, 202107)The El Niño Southern Oscillation (ENSO) is one of the most powerful climate phenomena that can change global air circulation, affecting temperature and rainfall around the planet. ENSO has three phases: El Niño and La ... 
Attenuation simulations and hardware design for the nuSol Spacebased Neutrino Probe
(Wichita State University, 20210402)INTRODUCTION: The nuSol project aims to design, build, and launch a small payload which will perform several nearsolar approaches in order to demonstrate the viability of a spacebased neutrino detector and perform ... 
The BAyesian STellar algorithm (BASTA): a fitting tool for stellar studies, asteroseismology, exoplanets, and Galactic archaeology
(Oxford University Press, 20210929)We introduce the public version of the BAyesian STellar Algorithm (BASTA), an opensource code written in PYTHON to determine stellar properties based on a set of astrophysical observables. BASTA has been specifically ... 
Bayesian variable selection and estimation in quantile regression using a quantilespecific prior
(Springer Science and Business Media Deutschland GmbH, 20220119)Asymmetric Laplace (AL) specification has become one of the ideal statistical models for Bayesian quantile regression. In addition to fast convergence of Markov Chain Monte Carlo, AL specification guarantees posterior ... 
Behavior of some CMC capillary surfaces at convex corners
(Pacific Journal of Mathematics at the University of California, 200604)We construct examples of nonparametric surfaces z = h(x, y) of zero mean curvature which satisfy contact angle boundary conditions in a cylinder in R3 over a convex domain with corners. When the contact angles for ... 
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) ... 
Biologically motivated quantum neural networks
(IEEE, 2017)This paper presents one step toward creating the building blocks for machine intelligence that is inspired by its biological equivalent. The authors' quantum learning methods (deep quantum learning) are applied to quantum ... 
Blocking duality for pmodulus on networks and applications
(Springer, 201906)This paper explores the implications of blocking dualitypioneered by Fulkerson et al.in the context of pmodulus on networks. Fulkerson blocking duality is an analog on networks to the method of conjugate families of curves ... 
A capillary surface with no radial limits
(Pacific Journal of Mathematics, 2018)In 1996, Kirk Lancaster and David Siegel investigated the existence and behavior of radial limits at a corner of the boundary of the domain of solutions of capillary and other prescribed mean curvature problems with contact ... 
Carleman estimates and applications to inverse problems
(Birkhäuser Verlag Basel/Switzerland, 2004)This review paper describes some general and recent results of possible interest for mathematicians studying or using uniqueness of the continuation or working on control theory or inverse problems for partial ... 
The Carleman formula and recovering the refractive index of the twodimensional Helmholtz equation
(2008)We consider the Cauchy problem for the Helmholtz equation with given bounded refrac tive index in an arbitrary planar domain with Cauchy data only on part of the boundary of the domain. We derive a Carlemantype formula ...
