| 1 | A model for virtual network embedding across multiple infrastructure providers using genetic algorithm显示文摘Network virtualization is an important aspect in cloud computing, where network is assumed to be consisting of infinite amount of nodes and links. The substrate network(physical network), has limited capacity and so virtual network embedding on the substrate network becomes a problem. Virtual network embedding is a computationally hard problem, considering various constraints on nodes and links. The proposed work applies Genetic Algorithm for the virtual network embedding problem for mapping multiple virtual network requests on infrastructure providers managing multiple substrate networks. Performance evaluation, through simulations,indicates that the proposed model preforms better for the performance metrics such as infrastructure provider revenue, acceptance ratio and node and link utilization in comparison to few other contemporary mapping models. | Isha PATHAK Deo Prakash VIDYARTHI | 2017 | Science China(Information Sciences)2017，60，4： | 2 |
| 2 | Primary implantation of non-valved glaucoma-drainage-device in sulcus in iridocorneal endothelial syndrome显示文摘Dear Editor,I ridocorneal endothelial syndrome(ICE)is a rare,usually unilateral,acquired condition,hypothesized to be secondary to a viral etiology[1].It affects females more often than males and comprises of three distinct clinical types related to endothelial proliferation and its structural abnormalities.Proliferation of endothelium over the iridocorneal angle leads to progressive secondary angle closure and that over the iris leads to typical changes of polycoria and atrophy.Three clinical entities included in the syndrome are Chandlers(predominant corneal involvement),progressive iris atrophy(predominant iris involvement with polycoria and‘holes’)and Cogan Reese(iris nodules with loss of stromal features).No matter what the clinical type,it is a progressive condition and controlling intraocular pressure(IOP)and maintaining corneal clarity in the long term is usually a challenge. | Vanita Pathak Ray Divya P Rao Isha Gulati | 2019 | International Journal of Ophthalmology(English edition)2019，12，11： | 1 |
