  2. 21. Cognitive Sensing and Transmission Strategies

    Author : Kasra Haghighi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hidden Markov Model; Spectrum Sensing; Sequential Spectrum Sensing; Cognitive Radio; Spectrum Utilization;

    Abstract : Many frequency bands for wireless services are severely underutilized by the primary users (PU) to which these bands are assigned. This motivates cognitive radios (CR), which identifies vacant spectrum and transmit accordingly. Many algorithms, some as simple as energy detection, are used to sense the spectrum. READ MORE

  4. 22. The use of structural information to improve biological sequence similarity searches

    Author : Jeanette Tångrot; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bioinformatik; Hidden Markov Model; HMM; protein structure alignment; protein structure superimposition; remote homologue; FISH-server; protein annotation; Bioinformatics; Bioinformatik;

    Abstract : Bioinformatics is a fast-developing field that make use of computational methods to analyse and structure biological data. An important branch of bioinformatics is structure and function prediction of proteins. To determine the structure of a protein is a crucial part in the characterisation of the molecule. READ MORE

  5. 23. Identification of novel antibiotic resistance genes through large-scale data analysis

    Author : Fanny Berglund; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metagenomics; hidden Markov model; carbapenemases; antibiotic resistance; big data; carbapenemases;

    Abstract : Antibiotic resistance is increasing worldwide, and is considered a serious threat to public health by e.g. the World Health Organization. Antibiotic resistance genes are hypothesized to originate from harmless bacteria in and around us, from where they are horizontally transfered into human pathogens. READ MORE

  6. 24. New antibiotic resistance genes and their diversity

    Author : Fanny Berglund; Chalmers tekniska högskola; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metagenomics; β-lactamases; hidden Markov model; antibiotic resistance; carbapenemases; big data; tetracycline resistance;

    Abstract : Antibiotic resistance is increasing worldwide and is considered a severe threat to public health. Often, antibiotic resistance is caused by antibiotic resistance genes, of which many are hypothesized to have been transferred into human pathogens from environmental bacteria. READ MORE

  7. 25. Sequence-based predictions of membrane-protein topology, homology and insertion

    Author : Andreas Bernsel; Gunnar von Heijne; Volkhard Helms; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; membrane protein; topology prediction; hidden markov model; homology detection; Sec translocon; Bioinformatics; Bioinformatik; Biochemistry; biokemi;

    Abstract : Membrane proteins comprise around 20-30% of a typical proteome and play crucial roles in a wide variety of biochemical pathways. Apart from their general biological significance, membrane proteins are of particular interest to the pharmaceutical industry, being targets for more than half of all available drugs. READ MORE
