PURPOSE It has been shown that visual deprivation leads to a myopic refractive error and also reduces the retinal concentration of dopamine. Exogenously 3,4-dihydroxy-L-phenylalanine (levodopa, L-DOPA) can be converted into dopamine in vivo, which safely and effectively treats Parkinson disease. Moreover, L-DOPA was also used in the treatment of amblyopia(More)
With the proliferation of cloud computing, the way of reasonable establishment of trust relationship among entities, as a vital part for forming security mechanism in cloud computing environments, is attracting increasing attention. This article introduces a trust management model based on fuzzy set theory and named TMFC including direct trust measurement(More)
Anti-inflammatory and anti-apoptotic effects of polydatin (PD) have been demonstrated in our previous studies. Recently, we have found that PD treatment can ameliorate burn-induced acute lung injury (ALI). In the present study, we hypothesized that PD may provide protective effect against LPS-induced ALI through reducing inflammation and apoptosis. Rats(More)
Compressive sampling is a new paradigm for sampling, based on sparseness of signals or signal representations. It is much less restrictive than Nyquist-Shannon sampling theory and thus explains and systematises the widespread experience that methods such as the Högbom CLEAN can violate the Nyquist-Shannon sampling requirements. In this paper, a CS-based(More)
The "Internet of Things"(IoT) opens opportunities for devices and softwares to share information on an unprecedented scale. However, such a large interconnected network poses new challenges to system developers and users. In this article, we propose a layered architecture of IoT system. Using this model, we try to identify and assess each layer's(More)
Aiming at the security and limited energy issues in wireless sensor network, this paper introduces a secure and energy-saving routing protocol based on cooperative game strategy. A novel incentive mechanism is proposed: all the nodes including the selfish ones are encouraged to forward packets and are rewarded if they help a cooperative sender or are(More)
In wireless sensor networks, how to detect the malicious nodes and prevent them from attacking the normal nodes has become one of the most important issues. This paper introduces a new mechanism in which the sensor nodes collaborate with each other to resist denial of service (DoS) attack and protect the being attacked nodes. A reputation-based incentive(More)
A facile one-step solution reaction route for growth of novel MoS2 nanorose cross-linked by 3D rGO network, in which the MoS2 nanorose is constructed by single-layered or few-layered MoS2 nanosheets, is presented. Due to the 3D assembled hierarchical architecture of the ultrathin MoS2 nanosheets and the interconnection of 3D rGO network, as well as the(More)
