• #### A novel Bayesian method for variable selection and estimation in binary quantile regression ﻿

(John Wiley & Sons, Ltd, 2022-07-03)
In this paper, we develop a Bayesian hierarchical model and associated computation strategy for simultaneously conducting parameter estimation and variable selection in binary quantile regression. We specify customary ...
• #### A pseudo restricted maximum likelihood estimator under multivariate simple tree order restriction and an algorithm ﻿

(Wichita State University, 2021-07)
The minimum distance projection of a given matrix $X \in R^{pxq}$ onto the order restricted cone in an appropriately defined inner product system, $\pi(X|C_{pxq}),$ plays an important role in order restricted statistical ...
• #### A strong law of large numbers for nonparametric regression ﻿

Suppose (i1,n, ..., in,n) is permutation of (1, ..., n) for each positive integer n such that the order of the indices {1, h., n - 1} in the permutation corresponding to n - 1 is preserved. If {Zn} is a sequence of mean-zero ...
• #### Accessibility and selective stabilization of the principal spin states of iron by pyridyl versus phenolic ketimines: modulation of the (6)a(1) <-> t-2(2) ground-state transformation of the [fen4o2](+) chromophore ﻿

(AMER CHEMICAL SOC, 2012-08-06)
Several potentially tridentate pyridyl and phenolic Schiff bases (apRen and HhapRen, respectively) were derived from the condensation reactions of 2-acetylpyridine (ap) and 2'-hydroxyacetophenone (Hhap), respectively, with ...
• #### An adaptive multiresolution interior penalty discontinuous Galerkin Method for wave equations in second order form ﻿

(Springer, 2020-10-04)
In this paper, we propose a class of adaptive multiresolution (also called adaptive sparse grid) discontinuous Galerkin (DG) methods for simulating scalar wave equations in second order form in space. The two key ingredients ...
• #### An adaptive multiresolution ultra-weak discontinuous Galerkin method for nonlinear Schrödinger equations ﻿

(Springer, 2021-01-25)
This paper develops a high-order 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 ...
• #### Adjusting neutrino interaction models and evaluating uncertainties using NOvA near detector data ﻿

(EDP Sciences, 2020-12-04)
The two-detector design of the NOvA neutrino oscillation experiment, in which two functionally identical detectors are exposed to an intense neutrino beam, aids in canceling leading order effects of cross-section uncertainties. ...
• #### Advanced forecasting model on land market value based on USA real estate market ﻿

(Wichita State University, 2019-12)
This research presents a time series estimation and prediction methods with the use of classic and advanced forecasting tools. Our discussion about di erent time series models is supported by giving the experimental forecast ...
• #### Advanced forecasting model on land market value based on USA real estate market ﻿

(Wichita State University, 2019-04-26)
This research presents a time series estimation and prediction methods with the use of classic and advanced forecasting tools. Our discussion about different time series models is supported by giving the experimental ...
• #### Ages of 70 dwarfs of three populations in the solar neighborhood: considering O and C abundances in stellar models ﻿

(IOP Publishing Ltd, 2016-12-15)
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 ...
• #### Ages of dwarfs in the solar neighborhood: considering C and O enhancements ﻿

(Institute of Physics Publishing, 2020-02-04)
Precise stellar ages of stars are necessary to study the evolution of the Milky Way. The age determination is significantly affected by C and O abundances of stars due to their contribution to the overall metallicity and ...
• #### Ages of main-sequence turnoff stars from the GALAH survey ﻿

(American Astronomical Society, 2022-04-01)
Main-sequence 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 ﻿

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 non-negatively curved 4-manifolds with torus symmetry ﻿

(American Mathematical Society, 2020-08-14)
We prove that if a closed, smooth, simply-connected 4-manifold with a circle action admits an almost non-negatively curved sequence of invariant Riemannian metrics, then it also admits a non-negatively curved Riemannian ...
• #### An analysis of the replies to the Kansas American Association of University Women's questionnaire on teacher welfare ﻿

(Wichita State University, 1948-05)
• #### An open-source implementation of the quick CSF method for rapid evaluation of contrast sensitivity ﻿

(Wichita State University, 2019-04-26)
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 ﻿

(Birkhäuser-Verlag, Basel, 2004-05-01)
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 ...
