Supersymmetric hyperbolic Calogero-Sutherland models by gauging
Nuclear Physics B, 2019 Novel N=2 and N=4 supersymmetric extensions of the Calogero-Sutherland hyperbolic systems are obtained by gauging the U(n) isometry of matrix superfield models. The bosonic core of the N=2 models is the standard An−1 Calogero-Sutherland hyperbolic system,

A Rotated Hyperbolic Wrapped Normal Distribution for Hierarchical Representation Learning
, 2022 We present a rotated hyperbolic wrapped normal distribution (RoWN), a simple yet effective alteration of a hyperbolic wrapped normal distribution (HWN). The HWN expands the domain of probabilistic modeling from Euclidean to hyperbolic space, where a tree

High Health Care Utilization Preceding Diagnosis With Juvenile Idiopathic Arthritis
Arthritis Care &Research, EarlyView.Objective Although early diagnosis improves long‐term outcomes, patients with juvenile idiopathic arthritis (JIA) often experience prolonged, circuitous paths to diagnosis. To inform diagnostic improvement, we sought to characterize health care utilization in the year preceding diagnosis. Methods We identified 10,021 patients with an incident diagnosis

Ruijsenaars-Schneider three-body models with N = 2 supersymmetry
Journal of High Energy Physics, 2018 The Ruijsenaars-Schneider models are conventionally regarded as relativistic generalizations of the Calogero integrable systems. Surprisingly enough, their supersymmetric generalizations escaped attention. In this work, N = 2 supersymmetric extensions of

Some Hyperbolic Iterative Methods for Linear Systems
Journal of Applied Mathematics, 2020 The indefinite inner product defined by J=diagj1,…,jn, jk∈−1,+1, arises frequently in some applications, such as the theory of relativity and the research of the polarized light.

Electronic Journal of Differential Equations, 2008 We study initial boundary-value problems for hyperbolic systems of divergence form of arbitrary order in cylinders whose base is a cusp domain. Our main results are to prove the existence, uniqueness and the smoothness with respect to time variable

WAVE SOLUTIONS FOR HYPERBOLIC SYSTEMS
Annals of the Academy of Romanian Scientists Series on Mathematics and Its ApplicationIn this paper we propose a reduction procedure for determining generalized traveling waves for first order quasilinear hyperbolic non-homogeneous systems. The basic idea is to look for solutions of the governing model that satisfy a further set of differential constraints. Some applications are given for a barotropic fluid with a source term.

Numerical methods for partial differential equations of hyperbolic type [PDF]
, 2019 The manual describe and examines modern numerical methods for the numerical solution of partial differential equa¬tions of hyperbolic systems. Hyperbolic equations can be found in many areas of physics and mechanics, such as acoustics, fluid dynamics ...

Arthritis Care &Research, EarlyView.Objective Race and household income impact outcomes in patients with rheumatic conditions; however, their role in pediatric antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis (AAV) remains poorly understood. We aimed to evaluate whether race and ethnicity and household income are associated with severe AAV disease and renal outcomes among
