in wireless sensor networks (wsns), localization algorithms could be range-based or range-free. the approximate point in triangle (apit) is a range-free approach. we propose modification of the apit algorithm and refer as modified-apit. we select suitable triangles with appropriate distance between anchors to reduce pit test errors (edge effect and non-uniform placement of neighbours) in apit a...

background: bilateral neck exploration is the gold standard for parathyroid adenoma localization in primary hyperparathyroidism. but surgeons do not have adequate experience for accurate surgical exploration and new methods are developed for surgery like unilateral exploration and minimally invasive surgery, thus, preoperative localization could reduces time and stress in surgical performance. ...

Wireless sensor networks attracting a great deal of research interest. Accurate localization of sensor nodes is a strong requirement in a wide area of applications. In recent years, several techniques have been proposed for localization in wireless sensor networks. In this paper we present a localization scheme with using only one mobile anchor station and received signal strength indicator tec...

glioblastoma is the most common and the most lethal primary brain cancer. this malignancy is highly locally invasive, rarely metastatic and resistant to current therapies. little is known about the distinct molecular biology of glioblastoma multiforme (gbm) in terms of initiation and progression. so far, several molecular mechanisms have been suggested to implicate in gbm development. homeodoma...

Over the past decade the economies of East Asia and APEC more generally have been increasinglyopening up their markets, and in the process have achieved significant gains in exports and economicgrowth. In conjunction with this increased economic integration, there has been increased recognitionby regional governments of the potential for a substantial increase in the participation by smallbusin...

he empirical studies have shown that cost advantages can occur due to economies of scale and economies of learning. However, a few studies have attempted to distinguish between these two effects on reducing costs. This paper is the first attempt on recognizing the impact of learning on reducing the cost with distinguishing the effect of economies of scale in Iran. Therefore, this study aims to ...

hydatid cyst locates in the liver (70%), lungs (25%) and rarely in other body tissues. cases with gluteal muscle localized hydatid cyst are rarely seen in literature. in this case report, a woman with hydatid cyst that was located in gluteal muscle was discussed. after the patient had been diagnosed, complete surgical excision was performed with the patient. albendazole treatment was applied in...
