Extant studies have suggested that Google search volume data can serve as a new and direct measure of investor attention in various research fields such as economy, financial and energy markets. However, it is not clear that whether investor attention influences prices in the same direction in different market states (prices increase or decrease). ...

This paper investigates the informational role of prices in segmented markets which are shocked by a kind of common sentiment resulting from financial contagion. This common sentiment bridges the connection between prices learned by rational traders and thus can weaken the uncertainty from noise shock. The authors find that there exist comovement e...

Many complex networks exist to facilitate the transport of material or information. In this capacity, the authors are often concerned with the continued flow of material or information when a fraction of the links in the complex network is disrupted. In other words, the authors are interested in the robustness of the complex network. In this paper,...

This paper is twofold. The first is devoted to study a class of quadratic rotation symmetric S-boxes (RSSBs) which was presented by Gao G, et al., Constructions of quadratic and cubic rotation symmetric bent functions, IEEE Transactions on Information Theory, vol. 58, no. 7, pp. 4908–4913, 2012, by decomposing a class of cubic rotation symmetric be...

In this paper, a robust finite-time tracking control scheme is proposed for wheeled mobile robots with parametric uncertainties and disturbances. To eliminate the effect of lumped uncertainties, a nonlinear extended state observer (NESO) is employed to estimate the unknown states as well as uncertainties, and the corresponding coefficients are tune...

This paper discusses the controllability problem of complex networks. It is shown that almost any weighted complex network with noise on the strength of communication links is controllable in the sense of Kalman controllability. The concept of almost controllability is elaborated by both theoretical discussions and experimental verifications.

With the fast growing economy, China has become the biggest automobile market in the world. Many Chinese families buy automobiles to promote individual wellbeing and facilitate the convenience of lives. Automobile purchase has become a general and important decision for a Chinese family. However, it is always difficult to make a decision on the aut...

This paper studies the identification of linear systems with quantized output observations. Recursive estimates for the linear system and the quantization thresholds are derived by the stochastic approximation algorithms with expanding truncations (SAAWET). Under suitable conditions, it is shown that the estimates converge to the true values almost...

This paper discusses a model for a repairable robot safety system composed of a safety component and two redundant robots according to a semi-group approach. The development of the model is divided into three phases: (I) The use of pure analysis to prove the uniqueness of a classical solution to the model; (II) The verification of this uniqueness b...
