• #### Accessing gluon polarization with high-${P}_{T}$ hadrons in SIDIS ﻿

(American Physical Society, 2023-02-27)
A recent global QCD analysis of jet production and other polarized scattering data has found the presence of negative solutions for the gluon helicity distribution in the proton, Δg, along with the traditional Δg > 0 ...
• #### Manifolds with nonnegative curvature operator of the second kind ﻿

(World Scientific Publishing Co., 2023-01-13)
We investigate the curvature operator of the second kind on Riemannian manifolds and prove several classification results. The first one asserts that a closed Riemannian manifold with three-positive curvature operator of ...
• #### Modeling the spread of the Coronavirus ﻿

(Wichita State University, 5/3/2020)
This talk will introduce statistical modeling concepts relating to prediction of COVID rates at a county level and specifically introduce the notion of spatial correlation, which recognizes that there is a connection between ...
• #### Computing the logarithmic capacity of compact sets having (infinitely) many components with the charge simulation method ﻿

We apply the charge simulation method (CSM) in order to compute the logarithmic capacity of compact sets consisting of (infinitely) many “small” components. This application allows to use just a single charge point for ...
• #### Measurement of the ν$_e$-Nucleus Charged-Current Double-Differential Cross Section at ⟨$E$$_ν$⟩=2.4 GeV Using NOvA ﻿

(American Physical Society, 2022-11-08)
The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using 8.02 ×10$^{20}$ protons-on-target in the NuMI beam. The sample of GeV electron neutrino interactions is the largest ...
• #### A brief treatise on the Joukowski transformation ﻿

(Wichita State University, 1954-06)
The problem of predicting the flight characteristics of an arbitrary airfoil is very complicated, and does not readily lend itself to exact mathematical methods. However if certain simplifying assumptions are made the ...
• #### Topics in theory of numbers ﻿

(Wichita State University, 1954-05)
• #### Eigenvalue estimates on Quaternion-Kähler manifolds ﻿

(Springer, 2023-01-09)
We prove lower bound estimates for the first nonzero eigenvalue of the Laplacian on a compact quaternion-Kähler manifold. For the closed or Neumann case, the lower bounds depend on dimension, diameter, and lower bound of ...
• #### Concept for a space-based near-solar neutrino detector ﻿

(Elsevier B.V., 2023-04-01)
The concept of putting a neutrino detector in close orbit of the Sun has been unexplored until very recently. The primary scientific return is to vastly enhance our understanding of the solar interior, which is a major ...

• #### Observational constraints on the origin of the elements ﻿

(EDP Sciences, 2022-05-20)
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 ...
• #### Vector random fields on the probability simplex with metric-dependent covariance matrix functions ﻿

(Springer Nature, 2022-12-01)
This paper constructs a class of isotropic vector random fields on the probability simplex via infinite series expansions involving the ultraspherical polynomials, whose covariance matrix functions are functions of the ...
• #### Infinite products ﻿

(Wichita State University, 1953-06)
• #### Level sets of potential functions bisecting unbounded quadrilaterals ﻿

(Birkhauser, 2022-11-10)
We study the mixed Dirichlet–Neumann problem for the Laplace equation in the complement of a bounded convex polygonal quadrilateral in the extended complex plane. The Dirichlet/ Neumann conditions at opposite pairs of sides ...
