Let denote the Laplacian in the Euclidean space. The classic upper estimates, independent of the domain, for the gaps of eigenvalues of − , (− )2 and (− )k(k ≥ 3) were studied extensively by many mathematicians, cf. Payne, Polya and Weinberger [16], Hile and Yeh [10], Chen and Qian [2], Guo [8] etc.. The asymptotic behaviors of eigenvalues for degenerate elliptic operators were considered by Be...

In this paper, we study the Payne-Whitham (PW) model as a hyperbolic system of conservation laws with relaxation. After studying the Riemann problem for the homogeneous version of the PW model, we introduce three first-order numerical solution methods for solving the system. In these methods, the homogeneous part of the PW model is approximated by Godunovtype difference equations, and different...

Schnabel, Kou & Xu reported three new species of spongicolid shrimp from New Zealand. The present note, with ZooBank registrations, serve to validate the names Spongicoloides clarki, S. sonne and Spongiocaris antipodes by fulfilling Code conditions for nomenclatural availability. As such, date authorship take publication this note. Specimens are deposited at National Institute Water Atmosph...

Fundamental diagrams of vehicular traffic flow are generally multivalued in the congested flow regime. We show that such set-valued fundamental diagrams can be constructed systematically from simple second order macroscopic traffic models, such as the classical Payne-Whitham model or the inhomogeneous Aw-Rascle-Zhang model. These second order models possess nonlinear traveling wave solutions, c...

ABSTRACT We present a novel approach to deriving stellar labels for stars observed in MUSE fields making use of data-driven machine learning methods. Taking advantage the comparable spectral properties (resolution and wavelength coverage) LAMOST instruments, we adopt Payne (DD-Payne) model used on observations apply it fields. Remarkably, spite instrumental differences, according cross-validati...
