Inspired by this motivation, automatic classification of protein structure becomes one of major research approaches. However, how to extract compact and effective feature to characterize protein structure is still a challenge to it. In this paper, 3-D tertiary structure of protein fold is mapped into 2-D distance matrix which can be further regarded as gray level image. Firstly, gray level co-occurrence matrix (CoM) of distance matrix image (DMI) is calculated and four descriptors based on it are taken as the first group of features. Next, DMI is transformed into projection view by Radon transform. In succession, the projection magnitudes are analyzed by histogram of which four central moments are taken as the second group of features. After that, we depict the structural meanings of gray distribution, various angles and pixels distance of CoM respectively, and determine the angle band used in Radon transform by the second derivation of the variance of the projections along different orientations. Finally, the presented feature extraction is validated by classification of 27 types of folds, compared with several feature methods based on sequence or structure. The results show that the presented method achieves significant improvement than other methods in terms of both low feature dimension and high classification accuracy.","PeriodicalId":286158,"journal":{"name":"2009 International Association of Computer Science and Information Technology - Spring Conference","volume":"226 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128202177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both binary protein interactions and protein complexes have been recognized as valuable sources for protein functional study. Great portion of the binary protein interactions are, however, predicted or inferred ones by computational methods from protein complex data. Validity of these data remains yet in unacceptable status. Hence, it is necessary to combine binary protein interactions and protein complex data for the sake of comprehensiveness while making clear distinction between them in well classified organization. We constructed a web-based database system that combines binary protein interaction and protein complex data from the nine most reliable public databases. Especially, the system maintains validity of data by adequately categorizing PPIs into direct binary interaction, co-complex relationship, and predicted interaction. In addition, we implemented a comprehensive user interface by which they can access relevant information at maximum. For single or group of queried proteins and their homologs, the system reports binary interactions, complexes, protein conservation in complexes, and binary interactions in complexes with their respective evidences. Our system would be a useful resource for identification of functionally correlated candidates in more reliable and comprehensive way.

But intrusions and misuses have always threatened the secured data communication over networks. Consequently, network security has come into issue. Now-a-days intrusion detection systems play an important role in security infrastructures. Intrusions typically start with intruders infiltrating a network through a vulnerable host and after that approaching for further malicious attacks. The techniques used for intrusion detection have their particular limitations. Any of the Intrusion Detection Systems proposed so far is not completely flawless. The host based systems as well as the network based systems have their own limitations. So, the quest for betterment continues. In this progression, here we present NIDS: a complete intrusion detection system which reduces some significant problems contained by the previous systems such as trust issues and message spreading problems. In the proposed IDS we don’t need to install the system for every host. That reduces the system overhead to a reasonable extent. This system generates steady responses against intrusions and stops the intruder to proceed for further attacks.","PeriodicalId":286158,"journal":{"name":"2009 International Association of Computer Science and Information Technology - Spring Conference","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122268412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we present the challenges, experience and accomplishments in the transient measurements of cells by flow cytometry and cell separation by fluorescence activated cell sorting (FACS). In contrast to the conventional method of characterization of novel or natural human pathogens, gene sequencing and neighbor joining tree have been considered more robust. We have used these approaches involving 16s rRNA gene sequencing of human pathogens (sequences with accession numbers EF419181, EF419183 & EF419182 deposited in the GenBank, USA) and neighbor joining tree to identify and characterize human pathogens (strains deposited in the publicly accessible international culture collections namely NCIMB, Scotland & NCCB, Netherlands). We found that combining multiparametric flow cytometry and FACS unveiled key information on the stress response of human pathogens. With the use of flow cytometry, we report for the first time, the phenomenon of DNAdh in Acinetobacter baylyi, an important nosocomial pathogen in humans. We forecast that DNAdh offers multilayer defense for human pathogens under stress. Furthermore, our strategies offer platform for disclosing genetic pathway(s) of dormancy and DNAdh, for the possible design of new generation of drugs and antimicrobials.","PeriodicalId":286158,"journal":{"name":"2009 International Association of Computer Science and Information Technology - Spring Conference","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132629962","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
