Rapid advances in wireless sensor networks require routing protocols which can accommodate new types of power source and data of differing priorities. We describe a priority-based geographical routing scheme based on a solar-cell energy model. It exploits an algorithm (APOLLO) that periodically and locally determines the topological knowledge range of each(More)
This paper proposes a reliable wildfire monitoring system based on a wireless sensor network (WSN) sparsely deployed in adverse conditions. The physical environment under consideration is characterized by asymmetric, irregular, and unreliable wireless links, inadequate Fresnel zone clearance, and routing problems, to name a few. We use reliable(More)
Most existing routing protocols for wireless sensor networks have energy efficiency as their main objective. But for WSN systems in which various types of data coexist, a different QoS (quality of service) metric is required. We describe a mission-oriented selective routing scheme that runs on each node of a network and invokes different algorithms for data(More)
This study evaluated the effects of glucose in human retinal pigment epithelial (RPE) cells to investigate the cause of diabetic retinal complications. Human RPE cells were cultured in media containing 5.5 mM, 11.0 mM, and 16.5 mM D-glucose. The present study performed proliferation and migration assays, and conducted western blotting for the protein(More)
We examined the association between the Catechol-O-methyltransferase (COMT) Val158Met polymorphism and aggressive schizophrenia. The sample included 61 aggressive schizophrenic patients as well as 104 non-aggressive patients from psychiatric hospitals and 415 healthy volunteers in South Korea. In the case-control comparisons, there was no significant(More)
Dihydroxy stilbene derivatives were designed based on lithospermic acid B and were prepared from 4-(chloromethyl)benzoic acid. The inhibitory activities of the novel compounds against protein tyrosine phosphatase 1B (PTP1B) were evaluated. 3,4-Dihydroxy stilbene carbonyl compounds (7, 11b, 27b) inhibited PTP1B with IC50 values comparable to molybdate, while(More)
