  1. 1. Excitonic Effects and Energy Upconversion in Bulk and Nanostructured ZnO

    Författare :Shula Chen; Irina Buyanova; Weimin Chen; Detlev M. Hofmann; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Zinc Oxide (ZnO), a II-VI wurtzite semiconductor, has been drawing enormous research interest for decades as an electronic material for numerous applications. It has a wide and direct band gap of 3.37eV and a large exciton binding energy of 60 meV that leads to intense free exciton (FX) emission at room temperature. LÄS MER

    Sammanfattning : Zinc Oxide (ZnO) is an extensively researched II-VI wide bandgap semiconductor material. As a promising material for future optoelectronic and spintronic applications, it continues to attract enormous amount of interest. LÄS MER

  4. 3. Ultrasensitive Molecular Monitoring of Breast Cancer and Acute Myeloid Leukemia

    Författare :Yilun Chen; Translational Oncogenomics; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; AML; PTEN; PI3K; Liquid biopsy; Sequencing; cfDNA; ctDNA; Structural variants; Mammography; CTC; Mutation detection; IBSAFE; MRD;

    Sammanfattning : Cancer is the common name to a group of biologically diverse malignant neoplastic diseases. Approximately 18 million people are diagnosed with cancer annually and 8.8 million patients die from it. Tumorigenesis and progression of cancer are driven by alterations in the cancer cell genome.

  5. 4. Genetic and Environmental Factors in Cardiometabolic Risk

    Författare :Yan Chen; Genetisk och molekylär epidemiologi; []
    Nyckelord :;

    Sammanfattning : Abstract: Cardiovascular diseases and diabetes mellitus are closely linked by sharing common risk factors, such as obesity, insulin resistance, hypertension and dyslipidaemia. These intermediate risk factors are affected by the joint effects of environment and genetics. LÄS MER

  7. 5. Continuity and compositions of operators with kernels in ultra-test function and ultra-distribution spaces

    Författare :Yuanyuan Chen; Joachim Toft; Nenad Teofanov; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Composition; modulation spaces; positivity; pseudo-differential operators; Schatten-von Neumann operators; twisted convolutions; ultra-distributions; Matematik; Mathematics;

    Sammanfattning : In this thesis we consider continuity and positivity properties of pseudo-differential operators in Gelfand-Shilov and Pilipović spaces, and their distribution spaces. We also investigate composition property of pseudo-differential operators with symbols in quasi-Banach modulation spaces. LÄS MER
