Data Flow Analysis (DFA for short) is a basic technique to collect statical information on run-time behaviors of programs: it is essential in optimizing compilers and is also used in type inference problems [1]. When performing a DFA, the program to be analysed is modeled by its Control Flow Graph (CFG) and by a set of transformation functions, one for each node in the graph. The set of program...

We present VisFlowConnect-IP, a network flow visualization tool that allows operators to detect and investigate anomalous internal and external network traffic. We model the network on a parallel axes graph with hosts as nodes and traffic flows as lines connecting these nodes. We present an overview of this tool’s purpose, as well as a detailed description of its functions.

In 65 patients with primary invasive ductal breast carcinoma the relation between classic prognosticators describing the extent of disease (lymph node metastases and tumour size) and newer promising morphometric and DNA flow cytometric prognostic factors was studied. There was no relation between DNA ploidy, lymph node state, and tumour size. Tumours with a mitotic activity index of more than 1...

Program analysis tools typically work on a representation of code as a control-flow graph (CFG), which is a graph-based representation of the flow of control through the program. It connects simple instructions in a way that statically captures all possible execution paths through the program and defines the execution order of instructions in the program. When control could flow in more than on...

We assessed segmental distribution of blood flow to the right atrium and the region of the sinoatrial node using micropheres (7-10 mum) in 20 anesthetized dogs. Mean right atrial flow averaged 83+/-7 (SE) ml/min X 100 g, which was 56% of the left ventricular blood flow. The distribution of right atrial flow was not homogeneous. For example, flow to anterior right atriaater (105+/-8 ml/min X 100...

The vertebrate body plan has conserved handed left-right (LR) asymmetry that is manifested in the heart, lungs, and gut. Leftward flow of extracellular fluid at the node (nodal flow) is critical for normal LR axis determination in the mouse. Nodal flow is generated by motile node cell monocilia and requires the axonemal dynein, left-right dynein (lrd). In the absence of lrd, LR determination be...

This paper presents an efficient, fixed point based algorithm for precise kill/gen analysis of interprocedural flow graphs with thread creation. The main idea of the algorithm is to separate a path reaching a control node into those steps required to reach the node and interfering steps, that are executed concurrently. These two parts are analyzed separately and combined afterwards. Exploiting ...

background and objectives: involvement of lymph nodes is an important prognostic factor in the most cancers, including colorectal cancer. in the recent years, invasion to blood and lymphatic vessels has been shown to predict involvement of lymph nodes and the number of involved nodes has been less studied issue. the aim of this study was determination of the relationship between the size of col...

We develop an analytic model for traffic flow analysis in a multi-hop wireless sensor network subject to node failure through a queueing theoretic framework. The dynamics of traffic flow in the source-to-sink path is modeled by a number of singleserver queues with finite capacity linked in tandem. Both the blocking effect of tandem queues due to limited buffer and the impact of node failure due...
