OBJECTIVE The actual status of stage migration in colon cancer that occurs in the procedure of preparing pathological specimens of lymph nodes has not been fully investigated. METHODS A nationwide survey of specialist institutions for colon cancer treatment was conducted to clarify interinstitutional differences in processing surgical specimens. After categorizing 111 institutions on the basi...

background in the diagnosis of malignant lymph nodes (lns) and staging of lung cancer, sampling of mediastinal and hilar lns is essential. mediastinoscopy is known as the gold standard. convex probe (cp) endobronchial ultrasound (ebus)-guided transbronchial needle aspiration (tbna) is a noninvasive and highly sensitive diagnostic method in mediastinal and hilar ln sampling. objectives evaluatin...

A wireless sensor network is capable of sensing physical quantities like pressure, humidity, temperature, real time object and also in the healthcare, and send these reports to the sink (i.e. the central entity), which will process the data and give an output understandable to a human. Wireless sensor network includes hundreds or thousands of sensor nodes. The sensor nodes are having very less ...

A large number of manufacturing operation planning problems can be formulated as state space search problems In case of sheet metal bending operation planning processing a search node involves extensive geometric reasoning Such computation intensive node processing limits the number of search nodes that can be expanded in a reasonable amount of time making it di cult to solve real life operatio...

Mobile sensor networks consist of a number of sensor nodes which are capable of sensing, processing, communicating and moving. These mobile sensor nodes move around and explore their surrounding areas. Top-k queries are useful in many mobile sensor network applications. However, the mobility of sensor nodes incurs new challenges in addition to the problems of static sensor networks (i.e., resou...

This paper presents a novel scheme for self configured dynamic sensor networks based on zones, where sensor nodes are location aware. Location about which sensors provide information is always more important than identification of sensors. It is vital to deliver this information to sink involving minimum packet processing at intermediate nodes due to limited battery life and bandwidth. This sch...

XML data can be represented by a tree or graph structure and XML query processing requires the information of structural relationships among nodes. The basic structural relationships are parent-child and ancestor-descendant, and finding all occurrences of these basic structural relationships in an XML data is clearly a core operation in XML query processing. Several node labeling schemes have b...

This paper presents a Grid-based parallel Event Processing System (GEPS) that is applicable to all the domains where large collections of separate blocks of data (images) need to be processed, stored and analyzed. Data intensive applications are becoming increasingly important in many science areas. In many domains the need for future computing and data management capabilities is difficult to a...

Large search engines are complex systems composed by several services. Each service is composed by a set of distributed processing nodes dedicated to execute a single operation required to user queries. One of these services is in charge of computing the top-k document results for queries by means of a document ranking operation. This ranking service is a major bottleneck in efficient query pro...
