Community detection in social networks is a well-studied problem. A community in social network is commonly defined as a group of people whose interactions within the group are more than outside the group. It is believed that people’s behavior can be linked to the behavior of their social neighborhood. While shared characteristics of communities have been used to validate the communities found, to the best of authors’ knowledge, it is not demonstrated in the literature that communities found using social interaction data are like-minded, i.e., they behave similarly in terms of their interest in items (e.g., movie, products). In this paper, we experimentally demonstrate, on a social networking movie rating dataset, that people who are interested in an item are socially better connected than the overall graph. Motivated by this fact, we propose a method for finding communities wherein like-mindedness is an explicit objective. We find small tight groups with many shared interests using a frequent item set mining approach and use these as building blocks for the core of these like-minded communities. We show that these communities have higher similarity in their interests compared to communities found using only the interaction information. We also compare our method against a baseline where the weight of edges are defined based on similarity in interests between nodes and show that our approach achieves far higher level of like-mindedness amongst the communities compared to this baseline as well. 相似文献
ABSTRACTNanoparticles of neodymium phosphate and 5% gadolinium (Gd) doped neodymium phosphate prepared by co-precipitation technique belong to the monoclinic monazite phase with space group P21/n. The average crystallite size calculated using Debye-Scherrer and Williamson Hall method matches very well with grain size observed from scanning electron microscope images and Image J software. FTIR analysis signifies the presence of vibration modes along with the phosphate group and a slight shift in wave number was observed with the substitution of gadolinium into neodymium phosphate. Ultraviolet absorption spectrophotometer show transitions from ground state to various excited state within the 4f shell and the absorption edge shifts towards the lower wavelength side (blue shift) with the addition of dopant. Raman spectrum further confirms the formation of phosphate group with relevant peaks. 相似文献
High-K Spacer based Dual-Metal Gate Stack Junctionless Gate All Around (HK-DMGS-JGAA) MOSFET has been proposed and analyzed in this paper for high frequency analog ad RF applications. It has been done by comparing it with the existing Junctionless devices in particular, Junctionless-Gate All Around, Junctionless Gate All Around Underlap and Dual-Metal Junctionless Gate All Around Underlap MOSFET. It is so found that HK-DMGS-JGAA MOSFET shows higher Ids, gm, gd and fT over existing Junctionless device architectures making it a suitable device for high frequency analog applications. It has also been established that HK-DMGS-JGAA MOSFET has better ION/IOFF ratio, Subthreshold Slope (SS) most close to the ideal values, lower Channel Resistance, Rch, higher Early Voltage (VEA), higher Frequency Transconductance Product, superior Transconductance Generation Factor, Maximum gains in terms of current gain, Maximum Transducer Power Gain and Unilateral Power Gain, superior noise performance in terms of the Noise Conductivity and Noise Figure. All these improved figure of merits warrant HK-DMGS-JGAA MOSFET as the best suited device design for various analog and digital applications along with high frequency applications.

Cancer diagnosis is currently undergoing a paradigm shift with the incorporation of molecular biomarkers as part of routine diagnostic panel. The molecular alteration ranges from those involving the DNA, RNA, microRNAs (miRNAs) and proteins. The miRNAs are recently discovered small non-coding endogenous single-stranded RNAs that critically regulates the development, invasion and metastasis of cancers. They are altered in cancers and have the potential to serve as diagnostic markers for cancer. Moreover, deregulating their activity offers novel cancer therapeutic approaches. The availability of high throughput techniques for the identification of altered cellular molecules allowed their use in cancer diagnosis. Their application to a variety of body specimens from blood to tissues has been helpful for appreciating their use in the clinical context. The development of innovative antibodies for immunohistochemical detection of proteins also assists in diagnosis and risk stratification. Overall, the novel cancer diagnostic tools have extended their application as prognostic risk factors and can be used as targets for personalized medicine. 相似文献
