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...

the imaging assessment of nodal disease can be challenging for the radiologist because there are multiple sites to review and differing opinions about criteria for abnormal nodes. the ability to accurately detect nodal metastases is improved with knowledge of the criteria for abnormal nodes, the nodal drainage patterns, and common imaging pitfalls. in this article, we introduce these basic conc...

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...

The Onion Router (TOR) online anonymity system is a network of volunteer’s nodes that allows Internet users to be anonymous through consecutive encryption tunnels. Nodes are selected according to estimated bandwidth (bnd) values announced by the nodes themselves. Some nodes may announce false values due to a lack of accuracy or hacking intention. Furthermore, a network bottleneck may occur when...

background: to evaluate the efficacy of color doppler ultrasound (cdus) in differentiating benign and malignant cervical lymph nodes by detecting differences in blood flow patterns. materials and methods: in this cross‑sectional prospective study, 25 untreated patients with clinical evidence of cervical lymphadenopathy were evaluated. cdus was performed for 80 cervical lymph nodes. the gray sca...

The arc costs are assumed to be online parameters of the network and decisions should be made while the costs of arcs are not known. The policies determine the permitted nodes and arcs to traverse and they are generally defined according to the departure nodes of the current policy nodes. In on-line created tours arc costs are not available for decision makers. The on-line traversed nodes are f...

wireless sensor networks (wsns) have many applications in the areas of commercial, military and environmental requirements. regarding the deployment of low cost sensor nodes with restricted energy resources, these networks face a lot of security challenges. a basic approach for preparing a secure wireless communication in wsns, is to propose an efficient cryptographic key management protocol be...

With the development of wireless communication technology, video communication over the mobile ad hoc networks has been more and more applied. How to ensure the QoS of video communication is an important problem that should be solved quickly. In this paper, we propose a QoS routing algorithm for Video Streaming in MANET. The algorithm introduces multi-constrained QoS routing mechanisms, optimiz...

this paper proposes an efficient network architecture to improve energy consumption in wireless sensor networks (wsn). the proposed architecture uses a mobile data collector to a partitioned network. the mobile data collector moves to center of each logical partition after each decision period. the mobile data collector must declare its new location by packet broadcasting to all sensor nodes. h...
