The WNT4 gene plays a crucial role in sexual differentiation and female genital tract development. This study screened WNT4 for mutation in 189 Chinese women with Müllerian duct abnormalities (10 Mayer-Rokitansky-Küster-Hauser syndrome, five Müllerian aplasia and 174 incomplete Müllerian fusion) and detected no perturbation that would indicate a major role(More)
The aim of this study was to determine if mutations in WNT5A contribute to the aetiology of Müllerian duct abnormalities (MDA) in 189 Chinese women. Three novel single-nucleotide polymorphisms (SNP; IVS2 - 115G >A, IVS4 + 66T >A, IVS4 + 102G >T) in introns 2 and 4 as well as one known SNP (rs62620048) in exon 6 were detected, but no causal mutations were(More)
Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers. Node placement problems have been investigated for a long time in the optimization field due to numerous applications in location science. In our previous work, we evaluated WMN-GA system which is based on Genetic Algorithms (GAs) to find an optimal location(More)
In this paper, we used our proposed and implemented system based on Hill Climbing algorithm, called WMN-HC for mesh router node placement in WMNs. We evaluate and compare the performance of the proposed system for different movement methods. We took into consideration Normal and Uniform distributions of mesh clients. We use as evaluation metrics giant(More)
In this paper we evaluate the performance of WMN-HC system for node placement in WMNs. For evaluation we considered different number of mesh routers and mesh clients. We considered four different mesh client distributions. The simulation results show that our proposed and implemented WMN-HC system can find the optimal number of mesh routers for covering a(More)
Node placement problems have been long investigated in the optimization field due to numerous applications in location science (facility location, logistics, services, etc) and classification (clustering). In this paper, we propose and implement a system based on Hill Climbing algorithm, called WMN-HC for mesh router node placement in WMNs. We evaluate the(More)
Wireless Mesh Networks (WMNs) are important networking infrastructure for providing cost-efficient broadband wireless connectivity. Mesh router node placement is important to achieve network connectivity and coverage in such networks. In this paper, we compare the performance of Genetic Algorithm (GA) and Hill Climbing (HC) for mesh router node placement in(More)
