Bounds for the spectral radius of block H-matrices

SPECTRAL RADIUS OF BLOCK H-MATRICES∗ WEI ZHANG† AND ZHENG-ZHI HAN† AMS subject classifications. 65F10, 65F15. 1. Introduction. H-matrices have important applications in many fields, such as numerical

Trend prediction of the 3D thermocline’s lateral boundary based on the SVR method

In recent years, with the use of the float-based wireless sensor network in the Argo project, a large amount of ocean data has been obtained. These data can be applied to analyze the oceanic thermocline, and the forecasting trend of the thermocline through the SVR method in machine learning is presented in this paper. Firstly, this paper refines the spatial resolution with the...

Regions containing eigenvalues of a matrix

CONTAINING EIGENVALUES OF A MATRIX∗ TING-ZHU HUANG†, WEI ZHANG‡, AND SHU-QIAN SHEN† 1. Introduction. The Gerschgorin circle theorem gives a region in the complex plane which contains all the eigenvalues of a ... | − ri(α)(A) |ρ(A) − ajj | − rj(β)(A) > ri(β)(A)rj(α)(A). 222 Ting-Zhu Huang, Wei Zhang, and Shu-Qian Shen Then, by Corollary 2.3, we can derive B is nonsingular. So if B is singular, there exists at

Fabrication of graphene film composite electrochemical biosensor as a pre-screening algal toxin detection tool in the event of water contamination

In this work, we fabricated a novel graphene film composite biosensor for microcystin-LR detection as an alternative to time-consuming, expensive, non-portable and often skills-demanding conventional methods of analysis involved in water quality monitoring and assessment. Excellent linear correlation (R2 = 0.99) of the electron-transfer resistance was achieved over a wide range...

Steady-State Analysis of Genetic Regulatory Networks Modelled by Probabilistic Boolean Networks

Probabilistic Boolean networks (PBNs) have recently been introduced as a promising class of models of genetic regulatory networks. The dynamic behaviour of PBNs can be analysed in the context of Markov chains. A key goal is the determination of the steady-state (long-run) behaviour of a PBN by analysing the corresponding Markov chain. This allows one to compute the long-term...

Histone deacetylase 6 in cancer

Histone acetylation and deacetylation are important epigenetic mechanisms that regulate gene expression and transcription. Histone deacetylase 6 (HDAC6) is a unique member of the HDAC family that not only participates in histone acetylation and deacetylation but also targets several nonhistone substrates, such as α-tubulin, cortactin, and heat shock protein 90 (HSP90), to...

Fault Diagnosis for Reducer via Improved LMD and SVM-RFE-MRMR

The vibration signals are usually characterized by nonstationary, nonlinearity, and high frequency shocks, and the redundant features degrade the performance of fault diagnosis methods. To deal with the problem, a novel fault diagnosis approach for rotating machinery is presented by combining improved local mean decomposition (LMD) with support vector machine–recursive feature...

Multivariate Splines-Based Asymmetric Aerodynamic Modeling of Morphing Aircraft

The aerodynamic parameters of morphing aircraft can vary significantly in the morphing process; the aerodynamic data model is complex and high-order nonlinear. This paper presents a new method of aerodynamic modeling of morphing aircraft by using multivariate splines. Firstly, the aerodynamic coefficient model of morphing aircraft based on the multivariate splines model structure...

The Quantum Effect on Friedmann Equation in FRW Universe

We study the modified Friedmann equation in the Friedmann-Robertson-Walker universe with quantum effect. Our modified results mainly stem from the new entropy-area relation and the novel idea of Padmanabhan, who considers the cosmic space to be emerging as the cosmic time progresses, so that the expansion rate of the universe is determined by the difference of degrees of freedom...

Nonlinear Dynamics of the High-Speed Rotating Plate

High speed rotating blades are crucial components of modern large aircraft engines. The rotating blades under working condition frequently suffer from the aerodynamic, elastic and inertia loads, which may lead to large amplitude nonlinear oscillations. This paper investigates nonlinear dynamic responses of the blade with varying rotating speed in supersonic airflow. The blade is...
