  1. 21. Scalable and Efficient Probabilistic Topic Model Inference for Textual Data

    Author : Måns Magnusson; Mattias Villani; Marco Kuhlmann; Jordan Boyd-Graber; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Text analysis; Bayesian inference; Markov chain Monte Carlo; topic models; Textanalys; Bayesiansk inferens; Markov chain Monte Carlo; temamodeller;

    Abstract : Probabilistic topic models have proven to be an extremely versatile class of mixed-membership models for discovering the thematic structure of text collections. There are many possible applications, covering a broad range of areas of study: technology, natural science, social science and the humanities. READ MORE

  2. 22. Temperature-dependent structure and function of group A streptococcal M proteins

    Author : Tommy Cedervall; Institutionen för experimentell medicinsk vetenskap; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Microbiology; plasma protein; fibrinogen; temperature; hydrophobicity; coiled-coil; Ig-binding; M protein; group A streptococcus; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Temperature-dependent structure and function of group A streptococcal M proteins.This thesis describes the temperature-dependent structure of the members in the group A streptococcal M protein family. M proteins are cell-surface proteins that are important for the bacterial virulence and bind to a diverse set of human plasma proteins. READ MORE

  3. 23. Biosynthesis of bacterial polysaccharides by novel glycosyltransferase enzymes

    Author : Shu-Chieh Chang; Yves S. Y. Hsieh; Ute Römling; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biotechnology; Bioteknologi;

    Abstract : Within the intricate microbiological realm, exopolysaccharides (EPS) emerge as a significant class of high molecular weight polysaccharides, serving pivotal roles in bacterial survival, virulence, communication, and defense against environmental adversities. The versatile nature of bacterial EPS extends beyond mere biological functions, reaching into medications, cosmetics, functional food, and sustainable industries. READ MORE

  4. 24. Exploring glycoside hydrolase family 5 (GH5) enzymes

    Author : Yang Wang; Ines Ezcurra; Henrik Aspeborg; Henrik Stålbrand; Torkel Berglund; KTH; []
    Keywords : GH5; glycoside hydrolase; subfamily classification; mannans; polysaccharides; mannanases; cell wall; GH5; glykosidhydrolas; subfamiljklassificering; mannaner; polysackarider; mannanaser; cellvägg; SRA - Molecular Bioscience; SRA - Molekylär biovetenskap;

    Abstract : In 1990, the classification of carbohydrate-active enzymes (CAZymes) was introduced by the scientist Bernard Henrissat. According to sequence similarity, these enzymes were separated into families with conserved structures and reaction mechanisms. READ MORE

  5. 25. Human Endogenous Retroviruses: Expression and Evolutionary Relationships

    Author : Marie-Louise Andersson; Avdelningen för medicinsk mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mikrobiologi; mycology; virology; bacteriology; Microbiology; bakteriologi; expression; transcription; reverse transcriptase; HERV; phylogeny; virologi; mykologi;

    Abstract : The human genome contains genetic elements which are more or less similar to infectious retroviruses. These are called human endogenous retroviruses (HERVs) and are thought to be remnants of infections in the primate lineage. READ MORE
