Clinical evidence suggests that nicotine reduces anxiety in stressful situations. In the present study, we investigated the effect of nicotine on restraint-enhanced anxiety-like behavior, c-Fos expression, an index of neuronal activation in the brain, and plasma corticosterone. Two-hour restraint stress-enhanced anxiety-like behavior in the elevated(More)
Many large-scaled servers are implemented as a peer-to-peer (P2P) distributed system to avoid centralized management and increase scalability. Traditional P2P lookup protocols often utilize binomial lookup trees to shorten lookup paths. Such a lookup protocol introduces routing bottlenecks when certain nodes become hot spots. In this paper, we present a(More)
This paper presents the architecture and implementation of an automatic medication dispenser specifically for users who take medications without close professional supervision. By relieving the users from the error-prone tasks of interpreting medication directions and administrating medications accordingly, the device can improve rigor in compliance and(More)
This paper presents a wireless biosignal acquisition system-on-a-chip (WBSA-SoC) specialized for electrocardiogram (ECG) monitoring. The proposed system consists of three subsystems, namely, 1) the ECG acquisition node, 2) the protocol for standard IEEE 802.15.4 ZigBee system, and 3) the RF transmitter circuits. The ZigBee protocol is adopted for wireless(More)
This paper describes the UCAADS simulation environment and the underlying UCAADS model that have been developed for the purpose of evaluating the correctness and performance of UCAADS and user-device interactions. The acronym UCAADS stands for user-centric automation and assistive devices/systems and services. Examples of UCAADS are medication dispenser,(More)
