    Sammanfattning : Research software is vital to advancement in the sciences, engineering, humanities, and all other fields. Scientific research is dependent on the quality of and accessibility to research software. LÄS MER

  3. 2. Genetic and Genomic Studies in Chicken : Assigning Function to Vertebrate Genes

    Författare :Jonas Eriksson; Leif Andersson; Greger Larson; Göran Hjälm; Tosso Leeb; Uppsala universitet; []
    Nyckelord :Chicken; BCO2; TSHR; COMTD1; Phenotypic variation; Domestication; Selective sweeps; Pigmentation; Molekylär genetik; Molecular Genetics;

    Sammanfattning : A major challenge in the post-genomic era is to understand how genome sequence variants (genotype) give rise to the enormous diversity observed in terms of morphology, physiology and behavior (phenotype) among living organisms. Domestic animals—with their tremendous phenotypic variation—are excellent model organisms for determining the relationships between genotype and phenotype. LÄS MER

  4. 3. Using enriched quality register data for health care evaluation : examples from rheumatoid arthritis

    Författare :Jonas Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Swedish registers have for decades successfully been used for medica research, enabling long-term follow-up of large patient cohorts using observational designs. With a tax funded health care system and the use of a personal identity number as a unique identifier, together with national health registers as well as national demographic registers, we have to a relatively low cost the possibility to answer an abundance of research questions in a real-world setting.

  5. 4. Advancements in Firefly Luciferase-Based Assays and Pyrosequencing Technology

    Författare :Jonas Eriksson; KTH; []
    Nyckelord :bioluminescence; osmolytes; glycine betaine; thermostability; firefly luciferase; inorganic pyrophosphatase; inorganic pyrophosphate; Pyrosequencing technology; secondary DNA-structures; Sequenase; Klenow-polymerase; reaction rates; temperature;

    Sammanfattning : Pyrosequencing is a new DNA sequencing method relying on thesequencing-by-synthesis principle and bioluminometric detectionof nucleotide incorporation events. The objective of thisthesis was improvement of the Pyrosequencing method byincreasing the thermal stability of firefly luciferase, and byintroducing an alternative DNA polymerase and a new nucleotideanalog.

  7. 5. Aspects of List-of-Two Decoding

    Författare :Jonas Eriksson; Thomas Ericson; Tom Høholdt; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; list decoding; Sudan s algorithm; Reed-Solomon code; Datatransmission; Datatransmission;

    Sammanfattning : We study the problem of list decoding with focus on the case when we have a list size limited to two. Under this restriction we derive general lower bounds on the maximum possible size of a list-of-2-decodable code. We study the set of correctable error patterns in an attempt to obtain a characterization. LÄS MER
