  2. 1. Complexities of Order-Related Formal Language Extensions

    Author : Martin Berglund; Frank Drewes; Henrik Björklund; Markus Holzer; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; complexity; automata; languages; order; shuffle; regular expressions; context-free; mildly context-sensitive; parsing; membership; algorithm analysis; Computer Science; datalogi;

    Abstract : The work presented in this thesis discusses various formal language formalisms that extend classical formalisms like regular expressions and context-free grammars with additional abilities, most relating to order. This is done while focusing on the impact these extensions have on the efficiency of parsing the languages generated. READ MORE

  4. 2. Complexities of Parsing in the Presence of Reordering

    Author : Martin Berglund; Frank Drewes; Bruce Watson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; parsing; membership problems; complexity theory; reordering; shuffle; mildly context-sensitive; formal languages; Computer Science; datalogi;

    Abstract : The work presented in this thesis discusses various formalisms for representing the addition of order-controlling and order-relaxing mechanisms to existing formal language models. An immediate example is shuffle expressions, which can represent not only all regular languages (a regular expression is a shuffle expression), but also features additional operations that generate arbitrary interleavings of its argument strings.

  5. 3. Intracellular regulation of TLR signaling Basic mechanisms and importance in intestinal inflammation

    Author : Martin Berglund; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TLR IL-1R signalling; Gαi2- - mice; IRAK; peritoneal macrophages; cross-tolerance; dextran sulfate sodium; IBD;

    Abstract : Toll-like receptors (TLRs) recognize conserved structures on/in microorganisms. The intracellular signalling pathways of TLRs are shared with IL-1R and IL-18R and their activation leads to transcription of proinflammatory cytokines and type-I interferons. READ MORE

  6. 4. Miniature Plasma Sources for High-Precision Molecular Spectroscopy in Planetary Exploration

    Author : Martin Berglund; Greger Thornell; Anders Persson; Felipe Iza; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEMS; MST; Optogalvanic Spectroscopy; Molecular Spectroscopy; Split-Ring Resonator; Microplasma; Teknisk fysik med inriktning mot mikrosystemteknik; Engineering Science with specialization in Microsystems Technology;

    Abstract : The prospect of finding life outside Earth has fascinated mankind for ages, and new technology continuously pushes the boundary of how remote and how obscure evidence we can find. Employing smaller, or completely new, types of landers and robots, and equipping them with miniature instruments would indeed revolutionize exploration of other planets and moons. READ MORE

  7. 5. Wood Hemicelluloses - Fundamental Insights on Biological and Technical Properties

    Author : Jennie Berglund; Mikael Lindström; Gunnar Henriksson; Francisco Vilaplana; Jakob Wohlert; Martin Lawoko; Maija Tenkanen; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; hemicellulose; wood; glucomannan; xylan; structure; acetylation; flexibility; solubility; interaction with cellulose; stability.; hemicellulosa; trä; glukomannan; xylan; struktur; acetylering; flexibilitet; löslighet; interaktion med cellulosa; stabilitet.; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Hemicelluloses are a group of heterogeneous polysaccharides representing around 30 % of wood where the dominating types are xylans, glucomannans and xyloglucans. Hemicelluloses complex molecular structure makes it difficult to understand the relationship between structure and properties entirely, and their biological role is not yet fully verified. READ MORE
