  1. 1. Protein structure prediction : Zinc-binding sites, one-dimensional structure and remote homology

    Författare :Nanjiang Shu; Sven Hovmöller; Bruce Donald; Geoff Barton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; protein structure prediction; zinc-binding; profile; homology detection; shape string; Bioinformatics; Bioinformatik; Molecular biology; Molekylärbiologi; Biochemistry; Biokemi; Structural Chemistry; strukturkemi;

    Sammanfattning : Predicting the three-dimensional (3D) structure of proteins is a central problem in biology. These computationally predicted 3D protein structures have been successfully applied in many fields of biomedicine, e.g. family assignments and drug discovery. LÄS MER

  4. 3. Riqueza léxica y expresión escrita en aprendices suecos de ELE : Proficiencia general, competencia léxica pasiva, tipo y complejidad de la tarea

    Författare :Marco Berton; María Bernal; Laura Sánchez Pérez; Folkert Kuiken; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; lexical richness; foreign language writing; Spanish; linguistic complexity; TBLT; task-based; task complexity; vocabulary; second language acquisition; riqueza léxica; ELE; producción escrita; complejidad lingüística; enfoque por tareas; complejidad de la tarea; vocabulario; adquisición de segundas lenguas; romanska språk med inriktning mot spanska; Romance Languages; Specialisation in Spanish;

    Sammanfattning : The present study explored lexical richness in the written production of Swedish university students of Spanish as a foreign language. Two aspects of lexical richness were investigated in the study, i.e., diversity (the ability to use a varied lexical repertoire), and sophistication (the proportion of relatively infrequent words).

  5. 4. Artefactual Intelligence: The Development and Use of Cognitively Congenial Artefacts

    Författare :David de Léon; Kognitionsvetenskap; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; pervasive computing; affective computing; persuasive computing; Psychology; Psykologi; computer-mediated extrospection; precommitment; self-control; situated cognition; distributed motivation; cognitive ethnography; distributed cognition; cognitive biographies; redesign; task–artefact cycle; artefact evolution; artefact design; task structure; cognitive task; cognitive congeniality; artefactual intelligence; cognitive artefacts; task environment; tools; Cognition; artefacts; ubiquitous computing;

    Sammanfattning : How can tools help structure tasks to make them cognitively easier to perform? How do artefacts, and our strategies for using them, develop over time in cognitively beneficial ways? These are two of the main questions that are explored in the five papers collected in this thesis. The first paper details an ethnographic study conducted on people cooking in their homes. LÄS MER

  7. 5. Parallelization of dynamic algorithms for electronic structure calculations

    Författare :Anton G. Artemov; Emanuel H. Rubensson; Maya Neytcheva; Bo Kågström; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parallelization; task-based programming; matrix algorithms; sparse matrices; inverse factorization; localized computations; density matrix methods; electronic structure calculations; Scientific Computing; Beräkningsvetenskap;

    Sammanfattning : The aim of electronic structure calculations is to simulate behavior of complex materials by resolving interactions between electrons and nuclei in atoms at the level of quantum mechanics. Progress in the field allows to reduce the computational complexity of the solution methods to linear so that the computational time scales proportionally to the size of the physical system. LÄS MER
