  2. 1. Spatial analysis and modeling of nerve fiber patterns

    Author : Claes Andersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hierarchical models; Bayesian estimation; epidermal nerve fibers; cluster processes; spatial point processes; diabetic neuropathy; Bayesian field theory; Diabetic neuropathies; Multilevel models Statistics ; Institutionen för matematiska vetenskaper. Tillämpad matematik och statistik.; CTH;

    Abstract : Diabetic neuropathy is a condition associated with diabetes affecting the epidermal nerve fibers (ENFs). This thesis presents analysis methods and models for ENF data, with two main puroposes: to find early signs of diabetic neuropathy and to characterize how this condition changes the nerve fiber structure.

  4. 2. Omics Data Analysis of Complex Diseases and Traits

    Author : Saman Hosseini Ashtiani; Arne Elofsson; Dirk Repsilber; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Omics data; RNA-seq; Microarrays; Metabolomics; Network analysis; Psoriasis; E. coli; Hip osteoporosis; Lung adenocarcinoma; Spearman s correlation coefficient; LC-MS; PCA; DEG; PPI; biokemi med inriktning mot bioinformatik; Biochemistry towards Bioinformatics;

    Abstract : Following the advent of the high-throughput techniques for producing massive omics data, new possibilities and challenges have also emerged in different fields of biology and medicine. Dealing with such data on different scales with different scopes such as genomics, transcriptomics, proteomics and metabolomics, demands appropriate data collection, preprocessing, statistical analysis, interpretation and visualization.

  5. 3. Optimizing nontarget workflows for identification of organic contaminants in various matrices

    Author : Florian Dubocq; Anna Kärrman; Thanh Wang; Juliane Hollender; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nontarget analysis; workflow optimization; statistical analysis; mass defect plot; organic contaminants; environmental matrices;

    Abstract : Since year 2000, production of chemicals around the world has more than doubled. Chemicals are used in many and diverse applications in our everyday life and even if their properties are useful, some can have a negative impact on environment and humans. READ MORE

  6. 4. Structures in High-Dimensional Data: Intrinsic Dimension and Cluster Analysis

    Author : Kerstin Johnsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : With today's improved measurement and data storing technologies it has become common to collect data in search for hypotheses instead of for testing hypotheses---to do exploratory data analysis. Finding patterns and structures in data is the main goal. READ MORE

  7. 5. Characteristics of Self-Injury in Young Adolescents : Findings from Cross-Sectional and Longitudinal Studies in Swedish Schools

    Author : Jonas Bjärehed; Institutionen för psykologi; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Non-suicidal self-injury; NSSI; Deliberate self-harm; DSH; Adolescents; cluster analysis;

    Abstract : Self-injury in adolescents (e.g. when individuals cut, burn, hit or otherwise deliberately cause themselves direct injury), has gained recognition as a potentially important mental health problem during the past decade. Relatively little has been known about the scope and characteristics of this behavior in Swedish adolescents. READ MORE
