Linearly repetitive Delone systems have a finite number of non periodic Delone system factors [PDF]

open access: yesarXiv, 2008
We prove linearly repetitive Delone systems have finitely many Delone system factors up to conjugacy. This result is also applicable to linearly repetitive tiling systems.

An Networked HIL Simulation System for Modeling Large-scale Power Systems [PDF]

open access: yesarXiv, 2020
This paper presents a network hardware-in-the-loop (HIL) simulation system for modeling large-scale power systems. Researchers have developed many HIL test systems for power systems in recent years. Those test systems can model both microsecond-level dynamic responses of power electronic systems and millisecond-level transients of transmission and ...

Distinct Alterations of Inflammatory Biomarkers in Cluster Headache: A Case Control Study

open access: yesAnnals of Neurology, EarlyView.
Objective Investigate the immune system's role in cluster headache by analyzing cytokines in people with cluster headache and headache‐free controls, and explore if certain cytokines could predict a specific phenotype. Methods We measured 45 cytokines in adult participants from the Danish Cluster Headache Biobank in a prospective case–control setup ...

Integral equivalence of multidimensional differential systems [PDF]

open access: yesarXiv, 2009
The bases of the theory of integrals for multidimensional differential systems are stated. The integral equivalence of total differential systems, linear homogeneous systems of partial differential equations, and Pfaff systems of equations is established.

Fractional Multidimensional System [PDF]

open access: yesarXiv, 2017
The multidimensional ($n$-D) systems described by Roesser model are presented in this paper. These $n$-D systems consist of discrete systems and continuous fractional order systems with fractional order $\nu$, $0<\nu<1$. The stability and Robust stability of such $n$-D systems are investigated.
