• #### An adaptive multiresolution ultra-weak discontinuous Galerkin method for nonlinear Schrödinger equations ﻿

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 ...
• #### 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 ...
• #### Separation of track- and shower-like energy deposits in ProtoDUNE-SP using a convolutional neural network ﻿

Liquid argon time projection chamber detector technology provides high spatial and calorimetric resolutions on the charged particles traversing liquid argon. As a result, the technology has been used in a number of recent ...
• #### Positively curved Riemannian orbifolds and Alexandrov apaces with circle aymmetry in Dimension 4 ﻿

(Deutsche Mathematiker Vereinigung, 2021-10-01)
We classify positively curved Alexandrov spaces of dimension 4 with an isometric circle action up to equivariant homeomorphism, subject to a certain additional condition on the infinitesimal geometry near fixed points which ...
• #### Polycircular domains, numerical conformal mappings, and moduli of quadrilaterals ﻿

We study numerical conformal mappings of planar Jordan domains with boundaries consisting of fnitely many circular arcs, also called polycircular domains, and compute the moduli of quadrilaterals for these domains. ...
• #### Conformal capacity and polycircular domains ﻿

(Elsevier, 2022-09-13)
We study numerical conformal mapping of multiply connected planar domains with boundaries consisting of unions of finitely many circular arcs, so called polycircular domains. We compute the conformal capacities of condensers ...
• #### Cluster analysis: A modern statistical review ﻿

(John Wiley and Sons Inc, 2022-08-19)
Cluster analysis is a big, sprawling field. This review paper cannot hope to fully survey the territory. Instead, it focuses on hierarchical agglomerative clustering, k-means clustering, mixture models, and then several ...
• #### Opportunities for nitrogen-vacancy-Assisted magnetometry to study magnetism in 2D van der Waals magnets ﻿

(American Institute of Physics Inc., 2022-08-08)
Exploring and understanding magnetism in two-dimensional (2D) van der Waals (vdW) magnetic materials present a promising route for developing high-speed and low-power spintronics devices. Studying their magnetic properties ...
• #### Positive (p,n)-intermediate scalar curvature and cobordism ﻿

(Elsevier, 2022-11-01)
In this paper we consider a well-known construction due to Gromov and Lawson, Schoen and Yau, Gajer, and Walsh which allows for the extension of a metric of positive scalar curvature over the trace of a surgery in codimension ...
• #### Improved measurement of neutrino oscillation parameters by the NOvA experiment ﻿

(American Physical Society, 2022-08-03)
We present new ν μ → ν e , ν μ → ν μ , ¯ ν μ → ¯ ν e , and ¯ ν μ → ¯ ν μ oscillation measurements by the NOvA experiment, with a 50% increase in neutrino-mode beam exposure over the previously ...
• #### NLO multijet merging for Higgs production beyond the VBF approximation ﻿

(Springer Nature, 2022-08-13)
We present results of the simulation of electroweak Higgs boson production at the Large Hadron Collider using both the NLO multijet merging and NLO matching frameworks provided by the general purpose event generator Herwig ...
• #### The construction of revised objective final examination in statistics ﻿

(Wichita State University, 1949-05)
During the past three years an examination constructed by Dr. C. B. Read, head of the mathematics department of the University of Wichita, has been given to 597 students as the final examination in beginning statistics ...
• #### Elementary applications of matrices ﻿

(Wichita State University, 1948-07)
This treatise is concerned principally with the fundamental properties of matrices, the basic operations which may be performed with them, and some of their applications to algebra, analytic geometry, and differential ...
