• #### Development of a neutrino detector capable of operating in space ﻿

(Elsevier B.V., 2023-02-01)
The ?SOL experiment to operate a neutrino detector close to the Sun is building a small test detector to orbit the Earth to test the concept in space. This detector concept is to provide a new way to detect neutrinos ...
• #### Strong local nondeterminism and exact modulus of continuity for isotropic Gaussian random fields on compact two-point homogeneous spaces ﻿

(Springer International Publishing, 2023-01-03)
This paper is concerned with sample path properties of real-valued isotropic Gaussian fields on compact two-point homogeneous spaces. In particular, we establish the property of strong local nondeterminism of an isotropic ...
• #### Manifolds with $4\frac{1}{2}$-Positive Curvature Operator of the Second Kind ﻿

(Springer Nature, 2022-08-04)
We show that a closed four-manifold with $4\frac{1}{2}$-positive curvature operator of the second kind is diffeomorphic to a spherical space form. The curvature assumption is sharp as both ${\mathbb{CP}\mathbb{}}^2$and ...
• #### 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 ...
• #### 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 ...
• #### 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 ...
• #### 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 ...
• #### Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC ﻿

(Springer, 2022-06-24)
DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6 × 6 × 6 m3 liquid argon time-projection-chamber (LArTPC) ...

(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 ...
• #### Stochastic comparison for elliptically contoured random fields ﻿

(Elsevier, 2022-10-01)
This paper presents necessary and sufficient conditions for the peakedness comparison and convex ordering between two elliptically contoured random fields about their centers. A somewhat surprising finding is that the ...
