Tra c congestion is quite common in urban settings, and is not always caused by tra c incidents. In this paper, we propose a simple method for detecting tra c incidents by using probe-car data to compare usual and current tra c states, thereby distinguishing incidents from spontaneous congestion. First, we introduce a tra c state model based on a probabilistic topic model to describe tra c stat...

The plasma membrane glycoprotein sodium/iodide symporter (NIS) is crucial for thyroid hormone biosynthesis and mediates the iodide uptake of thyrocytes. It has been shown that retinoic acid (RA) alters NIS gene expression in thyroid carcinoma lines and stimulates their iodide uptake. Here, we generated an ARO human thyroidal cancer cell line that expresses the NIS gene (ARO-NIS) and found that ...

In Drosophila melanogaster, the fruitless (fru) gene controls essentially all aspects of male courtship behavior. It does this through sex-specific alternative splicing of the fru pre-mRNA, leading to the production of male-specific fru mRNAs capable of expressing male-specific fru proteins. Sex-specific fru splicing involves the choice between alternative 5' splice sites, one used exclusively ...

preparation of tretinoin-containing microspheres with the aim of reducing undesirable skin reactions towards trans retinoic acid (tra) and thus, improving patient compliance is of particular interest. these microspheres have to be smaller than 30 m m to avoid causing gritty feel when applying on the skin, and slow the release of drug to minimize its skin side effects. following preliminary eval...

The Drosophila sex determination gene transformer-2 (tra-2) is a splicing regulator that affects the sex-specific processing of several distinct pre-mRNAs. While the tra-2 gene itself is known to produce alternative mRNAs that together encode three different TRA-2 protein isoforms, the respective roles of these isoforms in affecting individual pre-mRNA targets has remained unclear. We have gene...

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...
