Due to the increasing use of wireless communications, infrastructure-less networks such as Delay Tolerant Networks (DTNs) should be highly considered. DTN is most suitable where there is an intermittent connection between communicating nodes such as wireless mobile ad hoc network nodes. In general, a message sending node in DTN copies the message and transmits it to nodes which it encounters. A...

A 19-year-old girl referred to our clinic complaining of a painless lump on the left side of her tongue.  The patient had no history of dysphagia, lingual paresthesia or bleeding. Physical examination revealed the presence of multiple enlarged lymph nodes on the left side of her neck.  Histopathology of lingual mass and lymph nodes showed pleomorphic adenoma.  To our knowledge, this is the firs...

Adaptive networks include a set of nodes with adaptation and learning abilities for modeling various types of self-organized and complex activities encountered in the real world. This paper presents the effect of heterogeneously distributed incremental LMS algorithm with ideal links on the quality of unknown parameter estimation. In heterogeneous adaptive networks, a fraction of the nodes, defi...
