A prototype, content-based image retrieval system has been built employing a client/server architecture to access supercomputing power from the physician's desktop. The retrieves images and their associated annotations networked microscopic pathology database based on content similarity user supplied query images. Similarity is evaluated four feature types: color histogram, texture, Fourier coefficients, wavelet using vector dot product as distance metric. Current accuracy varies across...

Dendritic cells are potent stimulators of Ag-specific T cell responses and have been implicated in the pathogenesis HIV-1 other viral infections. Although cytokines may be involved both these processes, there is little information on expression by human blood dendritic cells. We characterized cytokine gene protein that were purified from normal PBMC flow cytometry stimulated vitro for up to 24 h with or herpes simplex virus (HSV). The unstimulated, uncultured defined their phenotype (HLA DR+...

Dendritic cells (DC) are potent APC that may be involved in the pathogenesis of HIV-1 infection. We studied function DC from HIV-1-infected subjects were derived monocyte-depleted PBMC by culture human IL-4 and granulocyte-macrophage CSF. The cultured had similar morphology phenotype mature (CD80 = 41 +/- 8%, CD86 77 5%, CD40 87 6%, CD1a 1 1%) to seronegative subjects. yield these was lower than HIV-1-seronegative (4 0% vs 11 2%, p < 0.01), yields correlated with numbers blood CD4+ T (r...

As part of collaboration between the Pittsburgh Supercomputing Center and University Medical we are developing methods for content based image retrieval to assist pathology diagnosis. We have been using Gleason grading prostate tumor samples as an initial domain evaluating effectiveness method specific tasks. In this application, system does not attempt directly reproduce pathologists' visual analysis. Rather, it relies on comparison features from a sample key similar but previously graded...

A superpoint is a host that communicates with large number of distinct destinations (sources) within measurement period. Identifying superpoints an important and meaningful task for network security monitoring. To keep up the line speed in high-speed network, fast memory indispensable detecting superpoints. Moreover, also expensive size-limited. In this letter, we propose new data streaming algorithm superpoints, called Snare, which can work tight space yield good performance. Its accuracy...

Abstract Three dimensional (3D) tubular braided composites are widely used in various industries due to their excellent mechanical properties and lightweight characteristics. However, traditional numerical experimental methods face challenges predicting quickly accurately factors such as ambient temperature, component materials, geometric parameters. To address this issue, paper combines deep neural networks (DNN) two‐scale finite element analysis accelerate the solution speed. The dataset...

Propositional satisfiability (SAT) is a fundamental problem of immense practical importance. While SAT NP-complete when clauses can contain 3 literals or more, the be solved in linear time given formula contains only binary (2SAT). Many complete search algorithms for solving have taken advantage 2SAT information that occurs statement order to simplify process, one we are aware uses arises process search, as simplified. There number possibilities making use improve process: maintaining during...

Correlated steganography considers the case in which cover work is chosen to be correlated with covert message that hidden. The advantage of this that, at least theoretically, number bits needed encode hidden can considerably reduced since it based on conditional entropy given cover. This may much less than itself. And if embed significantly reduced, then more likely steganographic algorithm will secure, i.e. undetectable. In paper, we describe an example steganography. Specifically, are...

Prostate cancer is the second most common cause of deaths and frequently detected form males in US. Death rate scan be greatly reduced by early treatment. Consequently, it important to understand progression this disease order improve detection treatment methods. As part Cancer Genome Anatomy Project work underway produce a 'molecular finger print' prostate cancer.
