  1. 1. Statistical analysis of gene expression data

    Författare :Erik Kristiansson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; gene expression; DNA microarrays; linear models; empirical Bayes; quality control; gene regulation; categorical data analysis; logistic regression; heavy metal stress; ecotoxicology; gene expression;

    Sammanfattning : Microarray technology has become one of the most important tools for genome-wide mRNA measurements. The technique has been successfully applied to many areas in modern biology including cancer research, identification of drug targets, and categorization of genes involved in the cell cycle. LÄS MER

    Sammanfattning : This thesis addresses a challenging problem: “how to let the visually impaired ‘see’ others emotions”. We, human beings, are heavily dependent on facial expressions to express ourselves. A smile shows that the person you are talking to is pleased, amused, relieved etc. LÄS MER

  5. 4. Vocal Expression of Emotion : Discrete-emotions and Dimensional Accounts

    Författare :Petri Laukka; Patrik N. Juslin; Erik Börjesson; Roddy Cowie; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; speech; emotion; vocal expression; emotion dimensions; acoustic cues; categorical perception; nonverbal communication; speech synthesis; cross-cultural communication; decoding accuracy; emotion intensity; meta-analysis; discrete emotions; Psykologi; Psychology; Psykologi;

    Sammanfattning : This thesis investigated whether vocal emotion expressions are conveyed as discrete emotions or as continuous dimensions. Study I consisted of a meta-analysis of decoding accuracy of discrete emotions (anger, fear, happiness, love-tenderness, sadness) within and across cultures. LÄS MER

  7. 5. Network and gene expression analyses for understanding protein function

    Författare :Oliver Frings; Erik Sonnhammer; Rune Linding; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biological networks; network inference; network analysis; clustering; network module; network crosstalk; expression analysis; gene signature; biomarker; biokemi; inriktning teoretisk kemi; Biochemistry with Emphasis on Theoretical Chemistry;

    Sammanfattning : Biological function is the result of a complex network of functional associations between genes or their products. Modeling the dynamics underlying biological networks is one of the big challenges in bioinformatics. LÄS MER
