Variety and veracity are two distinct characteristics of large-scale and heterogeneous data. It has been a great challenge to efficiently represent and process big data with a unified scheme. In this paper, a unified tensor model is proposed to represent the unstructured, semistructured, and structured data. With tensor extension operator, various types of(More)
This paper is concerned with the problem of robust peak-to-peak gain minimization by linear matrix inequality (LMI) approach. Instead of minimizing the robustly induced L ∞-norm, we minimize its upper bound. Results on the state-feedback controllers are obtained by this approach, and the controllers are at most the same order as the plant. One of the main(More)
Alzheimer's disease (AD) is an age-related progressive neurodegenerative disease, and early stage AD is characterized by synaptic dysfunction generally ascribed to soluble oligomers of amyloid-beta (Aβ). Neurotrophic factors are promising for AD treatment and are integrally involved in neuronal growth, survival and maintenance. Cerebral dopamine(More)
Glial cell line-derived neurotrophic factor (GDNF) has neuroprotective effects on dopaminergic (DA) neurons both in vivo and in vitro. However, substantial evidence has shown that a long-term overexpression of GDNF gene is often associated with side effects. We previously improved tetracycline (Tet)-On lentivirus system carrying human GDNF (hGDNF) gene, and(More)
— The problem of persistent bounded disturbance rejection for linear impulsive systems with parametric uncertainty is considered by Lyapunov function and positively invariant set analysis method. A sufficient condition for robustly internal stability and L 1-performance of the impulsive systems is obtained in terms of linear matrix inequalities. Based on(More)
This paper presents an improved particle filtering for hand tracking in a video sequence in real time. In this method, we incorporate mean shift process of elite particles into conventional particle filtering for hand tacking which aims to improve the tracking efficiency. The elite particles are chosen from the particles with higher weights based on(More)
