We present a novel HMM based approach to simultaneous segmentation of vessel walls in Lymphatic confocal images. The vessel borders are parameterized using RBFs to minimize the number of tracking points. The proposed method tracks the hidden states that indicate border locations for both the inner and outer walls. The observation for both borders is obtained using edge-based features from steer...

Vulvar cancer is a rare gynecological malignancy with mainly lymphatic spread. Sentinel node mapping plays an important role in the management of this gynecological malignancy. In the current study, we reported our experience in sentinel node mapping of vulvar cancer and review the literature accordingly. Since the introduction of sentinel node mapping to the surgical oncology community of our ...

Assume a communication scenario in wireless ad hoc and sensor networks where each node periodically sends out status information as a 1-hop broadcast to inform neighboring nodes. These scenarios are typical for monitoring and safety related applications where each node needs information about its neighborhood, e.g., in vehicular ad hoc networks. In IEEE 802.11 based ad hoc networks, one reason ...

background : interleukin (il)-4 is a member of t helper 2 (th2) axis produced by t-lymphocyte and mast cell. it has been shown that il-4 expression changes in tumor tissues. the main objective of this study is to investigate the expression of il-4 mrna in patients with laryngeal squamous cell carcinoma (lscc) with or without lymph node involvement. materials and methods: mrna expression of il-4...

Models of complex networks often incorporate node-intrinsic properties abstracted as hidden variables. The probability connections in the network is then a function these Real-world evolve over time and many exhibit dynamics node characteristics well linking structure. Here we introduce study natural temporal extensions static hidden-variable models with stochastic variables links. controlled b...

the notion of strong arcs in a fuzzy graph was introduced bybhutani and rosenfeld in [1] and fuzzy end nodes in the subsequent paper[2] using the concept of strong arcs. in mordeson and yao [7], the notion of“degrees” for concepts fuzzified from graph theory were defined and studied.in this note, we discuss degrees for fuzzy end nodes and study further someproperties of fuzzy end nodes and fuzz...

We consider the effect of Gaussian white noise on fast–slow dynamical systems with one fast and two slow variables, containing a folded-node singularity. In the absence of noise, these systems are known to display mixed-mode oscillations, consisting of alternating largeand small-amplitude oscillations. We quantify the effect of noise and obtain critical noise intensities above which the small-a...
