Capturing dependence among a large number of high dimensional random vectors is a very important and challenging problem. By arranging n random vectors of length p in the form of a matrix, we develop a linear spectral statistic of the constructed matrix to test whether the n random vectors are...

Statistical inferences for sample correlation matrices are important in high dimensional data analysis. Motivated by this, this paper establishes a new central limit theorem (CLT) for a linear spectral statistic (LSS) of high dimensional sample correlation matrices for the case where the...

In this paper, we used the production function method and the Van Norden method to estimate China's output gap (and potential output) from 1985 to 2009 year,and comparise the two methods. The results showed that: (1) the results of different methods are basically consistent with our economic...

The L2–L∞ fuzzy control problem is considered for nonlinear stochastic Markov jump systems with neutral time-delays. By means of Takagi–Sugeno fuzzy models, the fuzzy controller systems and the overall closed-loop fuzzy dynamics are constructed. A sufficient condition is firstly...

Spatial networks, also known as random geometric graphs, are random graphs with certain distance metric, in which each node is connected to some others within its neighborhood disc. Due to the rapid increase of network scales, the design of spatial networks becomes increasingly challenging....

China’s economy has been growing rapidly since the late 1970s and is expected to maintain this momentum in the foreseeable future. Coupled with the biggest population in the world, there is tremendous growth potential for China’s capital markets and financial services industry,...

Novel three-dimensional (3D) branched nanotubes of sodium niobate (NaNbO3) were produced by a multi-step reaction, which involves the synthesis of Nb2O5 branched nanowires and subsequently treating these precursors in alkali solution. XRD and SEM have been used to analyze current products. All...

Well-defined CdS branched nanorod arrays on ITO glass were fabricated via a facile one-step hydrothermal approach in large scale employing cadmium sulfide and thiourea as starting agents. Structural and morphological evolutions of CdS branched nanorod arrays were studied by scanning electron...
