In China, formal long-term care services for the large aging population have increased to meet escalating demands as demographic shifts and socioeconomic changes have eroded traditional elder care. We analyze China's evolving long-term care landscape and trace major government policies and private-sector initiatives shaping it. Although home and(More)
Understanding the transition of brain activity towards an epileptic seizure, called pre-epileptic seizure, is a challenge in epilepsy. In this Letter, a recurrence quantification analysis (RQA) is proposed to describe dynamical characteristics of EEG (electroencephalograph) recordings on rat experiments, which is helpful to predict seizures. One of the(More)
This study examines recent developments in institutional care for Chinese elders and attitudinal changes toward institutional care in Tianjin, China. Based on studies in 12 elder home sites and survey interviews with 265 older residents, this study compares institutional differences between government and non-government-owned elder homes, and examines(More)
In this note, the problem of control for a class of chaotic systems is studied. Only partial information of the systems states is known. First, an adaptive observer is designed to ensure the corresponding error system asymptotically stable. Then, based on the states obtained by the above observer, a nonlinear state feedback controller is constructed for the(More)
X-ray-based inspection technique is well applied to identification and evaluation of internal defects in castings, such as cracks, porosities, and foreign inclusions. Combining X-ray inspection with digital image processing and automatic image assessment is now the preferred approach for the continuous inspection of castings. However, in practical(More)
This paper is concerned with the function observer-based stabilization for time-varying delay systems with parameter uncertainties. The uncertain systems tackled in this paper involve uncertainty in quadratic constrained form which includes the well-known normbounded time-varying uncertainty as a special case. In terms of Razumikhin-type stability theorem,(More)
Remote tracking for mobile targets is one of the most important applications in wireless sensor networks (WSNs). A target tracking protocol– exponential distributed predictive tracking (EDPT) is proposed. To reduce energy waste and response time, an improved predictive algorithm–exponential smoothing predictive algorithm (ESPA) is presented. With the aid of(More)
In this paper, the problem of decentralized robust model reference control for a class of interconnected timedelay systems is investigated. The interconnections with timevarying time delays considered are high order and the gains are not known. A class of decentralized adaptive feedback controllers are proposed, which can render the resulting closed-loop(More)
Due to the high density of node deployment in wireless sensor network, the sensing data of nodes in spatially proximate locations are highly correlated. By effectively exploiting this spatial correlation in the data collection process, unnecessary energy costs for redundant data transmission can be largely reduced. In this paper, we focus on collecting(More)
The prediction of epileptic seizures is a very important issue in the neural engineering. This is because it may improve the life quality of the patients who are suffering from uncontrolled epilepsy. In our earlier work, we found that the dynamical characteristics of EEG data with recurrence quantification analysis (RQA), also called complexity measure, can(More)
