  1. 11. Bioinformatic Analysis of Mutation and Selection in the Vertebrate Non-coding Genome

    Författare :Mikael Brandström; Hans Ellegren; Diethard Tautz; Uppsala universitet; []
    Nyckelord :Biology; non-coding genome; selection; mutation; chicken; human; indel; microsatellite; sequence alignment; comparative genomics; bioinformatics; vertebrate; Biologi;

    Sammanfattning : The majority of the vertebrate genome sequence is not coding for proteins. In recent years, the evolution of this noncoding fraction of the genome has gained interest. These studies have been greatly facilitated by the availability of full genome sequences. LÄS MER

  3. 12. Analysis of Human Brain MRI : Contributions to Regional Volume Studies

    Författare :Richard Nordenskjöld; Joel Kullberg; Elna-Marie Larsson; Lars Johansson; Håkan Ahlström; Göran Starck; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Brain; Volume; Hemisphere; Intracranial volume; Image analysis; Computerized Image Analysis; Datoriserad bildanalys;

    Sammanfattning : Many disorders are associated with regional brain volumes. The analysis of these volumes from MR images often requires sequential processing steps such as localization and delineation. LÄS MER

  4. 13. Model Selection and Sparse Modeling

    Författare :Yngve Selén; Peter Stoica; Jean-Jacques Fuchs; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model selection; model order selection; model averaging; nested models; sparse models; Bayesian inference; MMSE estimation; MAP estimation; ML estimation; AIC; BIC; GIC; RAKE receivers; pulse compression; radar; linear models; linear regression models; Signal processing; Signalbehandling;

    Sammanfattning : Parametric signal models are used in a multitude of signal processing applications. This thesis deals with signals for which there are many candidate models, and it is not a priori known which model is the most appropriate one. LÄS MER

  5. 14. Immunoglobulin Gene Analysis in Different B cell Lymphomas : With Focus on Cellular Origin and Antigen Selection

    Författare :Mia Thorsélius; Richard Rosenquist Brandell; Christer Sundström; Anders Rosén; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; B cell lymphoma; Immunoglobulin; V gene; somatic hypermutation; antigen selection; quantitative PCR; Genetik; Clinical genetics; Klinisk genetik;

    Sammanfattning : B cell lymphoma (BCL) comprises a biologically and clinically heterogeneous group of tumors deriving from different stages of B cell development. The immunoglobulin (Ig) variable heavy chain (VH) gene rearrangement is unique for each BCL and can be used to reveal cellular origin, to study signs of antigen selection and to quantify tumor cell load.

  7. 15. Collaborative New Product Development : Supplier Selection and Purchasing

    Författare :Lisa Melander; Fredrik Tell; Nicolette Lakemond; Maria Elmquist; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Supplier selection; NPD; Purchasing; case studies;

    Sammanfattning : Suppliers provide new technology to firms and are important in firms‟ NPD. It is not sufficient for firms to select the most appropriate technology; they must also select the most appropriate supplier for their NPD. LÄS MER
