A 45-year-old woman from Afghanistan presented with a 1year history of multiple itching and stinging lesions on both right and left auricular and periauricular areas. Skin examination revealed about eight superficial erythematous nodules, ranging from 0.2 to 1.2 cm in diameter, on both ears, as well as on the preauricular and retroauricular areas (Fig. 1). Examination of a lesional skin biopsy specimen revealed vascular proliferation and dense dermal infiltration by lymphocytes, eosinophils, and mast cells. The vascular component consisted of thick- and thin- walled blood vessels lined by plump endothelial cells with large nuclei and abundant eosinophilic cytoplasm. No lymphoid follicles were identified (Fig. 2). The patient’ s medical history was rem.r.able for the gradual development of generalized edema starting 4 months after the appearance of the skin lesions. Laboratory investigation revealed the presence of massive proteinuria (11 g/day; normal,mg/day) and he- maturia (12 red blood cells/high- power field; normal,red blood cells/high- power field), in association with hypoproteinemia (3.7 g/dL; normal, 5.5- 8 g/dL and hypercholesterolemia (489 mg/dL; normal, 50- 220 mg/dL). The blood urea nitrogen (14 mg/dL; normal, 5- 23 mg/dL) and serum creatinine (0.8 mg/dL; normal, 0.6- 1.6 mg/dL) levels were within normal limits. A pathologic study of a renal biopsy specimen confirmed the diagnosis of diffuse mesangial proliferative nephropathy (Fig. 3).

A Configurable routing Protocol for Im.r.ving Lifetime and Coverage Area in Wireless Sensor Networks

引用

Wireless Sensor Network 2017年第9期9卷 311-332页

The particularities of Wireless Sensor Networks require specially designed protocols. Nodes in these networks often possess limited access to energy (usually supplied by batteries), which imposes energy constraints. Additionally, WSNs are commonly deployed in monitoring applications, which may intend to cover large areas. Several techniques have been proposed to im.r.ve energy-balance, coverage area or both at the same time. In this paper, an alternative solution is presented. It consists of three main components: Fuzzy C-means for network clustering, a cluster head rotation mechanism and a sleep scheduling algorithm based on a modified version of Particle Swarm Optimization. results show that this solution is able to provide a configurable routing protocol that offers reduced energy consumption, while keeping highcoverage area.
