Tra c estimation has been a long-studied problem, but prior work has mostly provided coarse estimates over large areas. This work proposes e ective ne-grained tra c volume estimation using invehicle dashboard mounted cameras. Existing work on tra c estimation relies on static tra c cameras that are usually deployed at crowded intersections and at some tra c lights. For streets with no tra c cam...

The B-ISDN will carry a variety of tra c types: the Variable Bit Rate tra c (VBR), of which compressed video is an example, Continuous Bit Rate tra c (CBR), of which telemetry is an example, Data tra c, and Available Bit Rate tra c (ABR) that represents aggregate data tra c with very limited guarantees on quality. Of these, VBR and CBR have timing constraints and need synchronous bandwidth; dat...

Several recent studies on a wide variety of networks have empirically observed that aggregate packet ows exhibit long-range dependence, i.e., the correlation between neighboring exclusive blocks of data does not asymptotically vanish when the block size is increased. Thus, actual network tra c is bursty over a broad range of time scales, in sharp contrast to conventional Markovian-type tra c mo...

BACKGROUND Percutaneous coronary intervention (PCI) through transradial approach (TRA) has shown to be safe and effective as transfemoral approach (TFA) among unselected patients. However, very few studies have compared the outcomes between TRA and TFA specifically in patients with a history of coronary artery bypass grafting surgery (CABG). METHODS A total of 404 post-CABG patients who had u...

R eal-time measurement and analysis of road trac ̄ow parameters such as volume, speed and queue are increasingly required for trac control and management. Image processing is considered as an attractive and ̄exible technique for automatic analysis of road trac scenes for the measurement and data collection of road trac parameters. In this paper, the authors describe a novel image processing b...

Activity of the sodium/iodide symporter (NIS) in lactating breast is essential for iodide (I(-)) accumulation in milk. Significant NIS upregulation was also reported in breast cancer, indicating a potential use of radioiodide treatment. All-trans-retinoic acid (tRA) is a potent ligand that enhances NIS expression in a subset of breast cancer cell lines and in experimental breast cancer models. ...

Long Range Dependent (LRD) network tra c does not behave like the tra c generated by the Poisson model or other Markovian models. From the network performance point of view, the main di erence is that LRD tra c increases queueing delays due to its burstiness over many time scales. LRD behavior has been observed in di erent types and sizes of networks, for di erent applications (eg. WWW) and di ...

Three genes, mgl A, B, and C, are required for active transport of substrate by the methylgalactose permease of E. coli K12. We report here that only two of these genes are required for substrate translocation, as seen by the ability or inability of isogenic mgl mutants (referred to as Tra+ and Tra minus, respectively) to grow on methyl-beta-D-galactopyranoside, supplied as sole carbon source. ...

PURPOSE Evaluate the response of human pancreatic cancer cell lines and orthotopic tumors to TRA-8, an agonistic antibody to death receptor 5, in combination with irinotecan (CPT-11). EXPERIMENTAL DESIGN MIA PaCa-2 and S2VP10 cells were treated with TRA-8 and/or CPT 11. Cell viability was determined by ATP assay. JC-1 mitochondrial depolarization and Annexin V assays confirmed cell death by a...

In the male germline of Drosophila the transformer-2 protein is required for differential splicing of pre-mRNAs from the exuperantia and att genes and autoregulates alternative splicing of its own pre-mRNA. Autoregulation of TRA-2 splicing results in production of two mRNAs that differ by the splicing/retention of the M1 intron and encode functionally distinct protein isoforms. Splicing of the ...
