  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 ...

• Eigenvalue estimates on Quaternion-Kähler manifolds 

  Li, Xiaolong; Wang, Kui (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 ...

• Numerical computation of a preimage domain for an infinite strip with rectilinear slits 

  Kalmoun, El Mostafa; Nasser, Mohamed M.S.; Vuorinen, Matti (Springer Link, 2023-01-16)

  Let Ω be the multiply connected domain in the extended complex plane $\overline {\mathbb {C}}$obtained by removing m non-overlapping rectilinear segments from the infinite strip $S=\{z : \left |\text {Im} z\right |<\pi ...

• Development of a neutrino detector capable of operating in space 

  Solomey, Nickolas (Elsevier B.V., 2023-02-01)

  The vSOL 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 

  Lu, Tianshi; Ma, Chunsheng; Xiao, Yimin (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 ...

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

  Tao, Zhanjing; Huang, Juntao; Liu, Yuan; Guo, Wei; Cheng, Yingda (Springer Link, 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 ...

• Manifolds with $4\frac{1}{2}$-Positive Curvature Operator of the Second Kind 

  Li, Xiaolong (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 ...

• Vector random fields on the probability simplex with metric-dependent covariance matrix functions 

  Ma, Chunsheng (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 

  Nasser, Mohamed M.S.; Nasyrov, Semen; Vuorinen, Matti (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 

  Abed Abud, Adam; Abi, B.; Meyer, Holger; Muether, Mathew; Roy, P.; Solomey, Nickolas (Springer Link, 2022-10-12)

  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 

  Harvey, John; Searle, Catherine (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 ...

• Positive (p,n)-intermediate scalar curvature and cobordism 

  Burkemper, Matthew; Searle, Catherine; Walsh, Mark (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 ...
