One-Class Collaborative Filtering (OCCF) is an emerging setup in collaborative filtering in which only positive examples or implicit feedback can be observed. Compared with the traditional collaborative filtering setting where the data has ratings, OCCF is more realistic in many scenarios when no ratings are available. In this paper, we propose to improve(More)
[1] We measured the carbon isotopic composition (d 13 C) of ecosystem respiration (d 13 C R) in a subalpine forest across four growing seasons to examine whether patterns in d 13 C R were consistent with those expected based on leaf‐level gas‐exchange theory, and in agreement with past studies of the relation between d 13 C R and climate conducted across(More)
Parkinson's disease (PD) is a progressive neurodegenerative disorder affecting predominantly the dopaminergic mesotelencephalic system. Enormous progress has been made in the treatment of PD. Our previous study has shown that hydroxysafflor yellow A (HSYA) could attenuate the neurotoxicity induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine in mice. In(More)
(WLANs). Analytical models of EDCA in the current literature have been mainly developed for the AIFS, CW, and TXOP schemes, separately. This study proposes a comprehensive analytical model to accommodate the combination of these three QoS schemes in WLANs under unsaturated traffic loads. We derive the performance metrics in terms of throughput, end-to-end(More)
Wireless mesh networks (WMNs) have emerged as a key technology for next generation wireless networks and provide a low-cost and convenient solution to the last-mile problem. Security and privacy issues are of paramount importance to WMNs for their wide deployment and for supporting service-oriented applications. Moreover, to support real-time services, WMNs(More)
Developing an intelligent e-Business portal needs various WI technologies. In order to represent, manage, integrate , share, and use the information coming from huge, distributed, multiple data sources, we present a conceptual model with dynamic multi-level workflows corresponding to a multi-layer Grid architecture for multi-aspect analysis in building an(More)
