1. 1. Taming of the BEAST

   Författare :Maja Loncar; Institutionen för elektro- och informationsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; tree search; product codes; list distance; list decoding; list-based SISO decoding; ML decoding; MAP decoding; iterative decoding; ISI equalization; BEAST; block codes; Teknik; Signal processing; Signalbehandling;

   Sammanfattning : Modern communication systems are designed to enable reliable and fast information transfer. Therefore, efficient channel coding and decoding strategies are needed, which guarantee sufficiently low probability of erroneous reception with affordable receiver complexity. LÄS MER

3. 2. Taxonomy and Reticulate Phylogeny of Heliosperma and Related Genera (Sileneae, Caryophyllaceae)

   Författare :Božo Frajman; Bengt Oxelman; Mats Thulin; Christian Brochmann; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sileneae; Silene; Heliosperma; Atocion; Viscaria; taxonomy; phylogenetics; relative dating; reticulate evolution; chloroplast capture; homoploid hybridisation; BEAST; r8s; PATHd8; Prometheus; RPA2; RPB2; RPD2a; RPD2b; Balkan Peninsula; endemics; Systematics and phylogenetics; Systematik och fylogeni;

   Sammanfattning : Heliosperma (nom. cons prop.) comprises 15—20 taxa, most of them endemic to the Balkan Peninsula. DNA sequences from the chloroplast (rps16 intron, psbE-petG spacer) and the nuclear genome (ITS and four putatively unlinked RNA polymerase genes) are used to elucidate phylogenetic relationships within Heliosperma, and its position within Sileneae.

4. 3. Desert Plants and Deserted Islands : Systematics and Ethnobotany in Caryophyllaceae

   Författare :Anneleen Kool; Mats Thulin; Gudrun Kadereit; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; BEAST; Corrigiola; DNA barcoding; Morocco; Pollichia; Polycarpon; Polycarpaea; RAxML; Sanctambrosia; Spergula; Spergularia; Sphaerocoma;

   Sammanfattning : Background. Caryophyllaceae is a large and cosmopolitic flowering plant family, however the systematics of many of its basal groups has been unclear, due to a lack of unambiguous morphology. Some members of Caryophyllaceae are used medicinally, e.g. LÄS MER

7. 5. Phylogenetic Relationships of Silene sect. Melandrium and Allied Taxa (Caryophyllaceae), as Deduced from Multiple Gene Trees

   Författare :Anja Rautenberg; Bengt Oxelman; Mikael Thollesson; Magnus Lidén; Freek Bakker; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Silene; Elisanthe; Melandrium; Conoimorpha; Caryophyllaceae; Silene multinervia; relative dating; extreme substitution rates; phylogeny; BEST; BEAST; cpDNA; mtDNA; RNA polymerase; RPA2; RPB2; RPD2; SlX1; SlY1; ITS; introgression; incongruent phylogenies; chromosome count; coalescent; Bayes Factors; Systematics and phylogenetics; Systematik och fylogeni; systematisk botanik; Systematic Botany;

   Sammanfattning : This thesis focuses on phylogenetic relationships among some of the major lineages in Silene subgenus Behenantha (Caryophyllaceae) using DNA sequences from multiple, potentially unlinked gene regions from a large taxonomic and geographic sample. Both traditional phylogenetic analyses and a strategy to infer species trees and gene trees in a joint approach are used. LÄS MER
