In this paper, an algorithm is proposed for detecting texts in images and video frames. It is performed by three steps: edge detection, text candidate detection and text refinement detection. Firstly, it applies edge detection to get four edge maps in horizontal, vertical, up-right, and up-left direction. Secondly, the feature is extracted from four edge(More)
Standard controls and best practice guidelines advance acceptance of data from research, preclinical and clinical laboratories by providing a means for evaluating data quality. The External RNA Controls Consortium (ERCC) is developing commonly agreed-upon and tested controls for use in expression assays, a true industry-wide standard control.
Primary human tissues are an invaluable widely used tool for discovery of gene expression patterns which characterize disease states. Tissue processing methods remain unstandardized, leading to unanswered concerns of how to best store collected tissues and maintain reproducibility between laboratories. We subdivided uterine myometrial tissue specimens and(More)
In this paper, we consider theMinimum Independent Dominating Set problem and develop exact exponential algorithms that break the trivial O(2|V |) bound. A simple O∗( √ 3 |V | ) time algorithm is developed to solve this problem on general graphs. For sparse graphs, e.g. graphs with degree bounded by 3 and 4, we show that a few new branching techniques can be(More)
Computational alignment of a biopolymer sequence (e.g., an RNA or a protein) to a structure is an effective approach to predict and search for the structure of new sequences. To identify the structure of remote homologs, the structure-sequence alignment has to consider not only sequence similarity, but also spatially conserved conformations caused by(More)
Organizations require security systems that are flexible and adaptable in order to combat increasing threats from software vulnerabilities, virus attacks and other malicious code, in addition to internal attacks. Network intrusion detection systems, which are part of the layered defense scheme, must be able to meet these organizational objectives in order(More)
It is well known that TCP does not perform well in networks with large propagation delay and high link loss probability, which are typical in hybrid space-terrestrial networks. Implementing Automatic-Repeat-Request (ARQ) retransmission over satellite links in hybrid networks has been proposed to enhance TCP performance by hiding the link losses from TCP.(More)
We propose an integrated framework that manages changes in long term composed services. The main procedure of change reaction is presented. One of the most challenging research issues of change management is how to automate the process of change reaction. To address this issue, we propose a semantic support, which centers around a tree-structured Web(More)
De novo sequencing and spectral alignment are computationally important for the prediction of new protein peptides via tandem mass spectrometry (MS/MS). Both approaches are established upon the problem of finding the longest antisymmetric path on formulated graphs. The problem is of high computational complexity and the prediction accuracy is compromised(More)
Polycomb repressive complexes (PRCs) play crucial roles in transcriptional repression and developmental regulation in both plants and animals. In plants, depletion of different members of PRCs causes both overlapping and unique phenotypic defects. However, the underlying molecular mechanism determining the target specificity and functional diversity is not(More)
