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 least mean-square (LMS) algorithm with ideal links on the quality of unknown parameter estimation. In heterogeneous adaptive networks, a fractio...

Geographic location information of nodes in ad hoc networks is useful for improved routing, lookup services, and location aware applications. This paper proposes a scheme that enables nodes of an adhoc network to discover their geographical location with good accuracy when only a few nodes know a-priori their exact location (e.g., through GPS) and the only additional information available to ot...

background: the impact of positive intramammary lymph node (im ln) on the prognosis of patients with breast cancer has been debated for years; likewise, the standard management of patients with positive im ln remains unclear, especially when it is identified by preoperative imaging or by sentinel lymph node biopsy. the present study aims at reviewing the level of concurrent involvement of im ln...

abstract: gridlock is an extreme traffic state where vehicle cannot move at all. this research studies the development of gridlock by theoretical and numerical analysis. it is shown that the development of gridlock can be divided into several stages. the core of the development is the evolution of congestion loop. a congestion loop is comprised of a number of consecutively connected spillover l...

A hierarchical self-organising neural network is described for the detection of unusual pedestrian behaviour in video-based surveillance systems. The system is trained on a normal data set, with no prior information about the scene under surveillance, thereby requiring minimal user input. Nodes use a trace activation rule and feedforward connections, modified so that higher layer nodes are sens...

510 cases of surgical lymph node biopsies during a five year periode are reviewed with the following conclusionsthe lymph node biopsy constitues 5% of all the surgical biopsies, the cervical and axillary lymph nodes are the most commonly biopsicd nodes due to their easy accessibility and due to the fact that they drain the lymph from many vital organs: the next most commonly biopsied nodes are ...

Most wireless sensor networks consist of a large number of static, low-power, short-lived, and unreliable sensors. In this paper, we considered sensor networks consisting of both static and mobile nodes. Integrating both types of devices enables new applications, such as nodes replacement, hole and partition recovery, and autonomous deployment and redeployment. We designed a smart mobile robot ...

Data based source localization in complex networks has a broad range of applications. Despite recent progress, locating multiple diffusion sources in time varying networks remains to be an outstanding problem. Bridging structural observability and sparse signal reconstruction theories, we develop a general framework to locate diffusion sources in time varying networks based solely on sparse dat...

lymph node dissection is of prime importance for accurate staging of colorectal carcinomas. since a great number of small lymph nodes are missed in the traditional method, several fat clearing solutions have been introduced for easier detection of smaller lymph nodes. in this study we evaluated the efficacy of a new fat clearing solution so-called lymph node revealing solution (lnrs) in colecto...
