  1. 1. Journalism at the borders : the constitution of nationalist closure in news decoding

    Författare :Johan Östman; Mats Ekström; Birgitta Höijer; John Corner; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; nationalist closure; nationalism; morality; news journalism; preferred meanings; encoding decoding; interpretive repertoires; referential; metalinguistic; Media and communication studies; Medie- och kommunikationsvetenskap; Media and Communication Studies; Medie- och kommunikationsvetenskap;

    Sammanfattning : This dissertation is a contribution to the social analysis of nationalism. Its disciplinary context comprises the field of empirical studies that explore how forms of mediated quasi interaction can function in processes of reproduction and transformation of nationality.

  3. 2. Wobble modifications and other features in transfer RNA important for decoding and reading frame maintenance

    Författare :Joakim Näsvall; Glenn Björk; Michael O'Connor; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transfer RNA; Modified nucleosides; Decoding; Reading frame maintenance; Molecular biology; Molekylärbiologi;

    Sammanfattning : Transfer RNA (tRNA) is the adaptor molecule responsible for bringing the correct amino acid to the ribosome during protein synthesis. tRNA contains a number of modified nucleosides, which are derivatives of the four normal nucleosides. LÄS MER

  4. 3. Decoding the complex brain : multivariate and multimodal analyses of neuroimaging data

    Författare :Alireza Salami; Lars Nyberg; Cheryl Grady; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; datoriserad bildanalys; Computerized Image Analysis;

    Sammanfattning : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.

  5. 4. Joint Source-Channel Coding using Trellis Coded CPM

    Författare :Zihuai Lin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iterative decoding; serially concatenated CPM; punctured ring convolutional codes.; trellis coded quantization; turbo codes; turbo trellis coded modulation; soft decoding; ring convolutional coded CPM; continuous phase modulation; Joint source channel coding;

    Sammanfattning : The thesis investigates Joint Source and Channel Coding(JSCC) using combined Trellis Coded Quantization (TCQ) and coded modulation. First we investigate a JSCC scheme using combined TCQ/Trellis Coded CPM (TCQ/TCCPM). Based on the BCJR algorithm for trellis coded CPM, we derive an optimal soft decoding algorithm for the considered systems. LÄS MER

  7. 5. Formation and function of wobble uridine modifications in transfer RNA of Saccharomyces cerevisiae

    Författare :Bo Huang; Anders Byström; Monica Rydén-Aulin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transfer RNA; Modified nucleoside; Elongator complex; Wobble uridine; Decoding; Molecular biology; Molekylärbiologi;

    Sammanfattning : Transfer RNAs (tRNAs) act as adaptor molecules in decoding messenger RNA into protein. Frequently found in tRNAs are different modified nucleosides, which are derivatives of the four normal nucleosides, adenosine (A), guanosine (G), cytidine (C), and uridine (U). LÄS MER
