  1. 1. Optical Memories and Processing in Time- and Frequency Domain

    Författare :Baozhu Luo; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical storage; photon echo; spectral hole burning; nonlinear optics; fiber amplifier; logical operation; phase retrieval; polarization holographic recording and retrieval; optical processing; Atomic and molecular physics; Atom- och molekylärfysik; Fysicumarkivet A:1998:Luo;

    Sammanfattning : Spectral hole burning and photon echoes are the techniques for frequency-selective optical memories, which have the potential to increase areal data storage density by a factor 10**7. They also have the capability to perform in-memory data processing. LÄS MER

  3. 2. Finite elements based on the piece-wise linear weight functions in contact problems

    Författare :Chouping Luo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The Finite Element Method (FEM) has been applied widely in solving many engineering problems. The FEM is an approximate method, which makes use of a spatial discretization and a weighted residual formulation to arrive at a system of matrix equations. LÄS MER

  4. 3. Deciphering the complexity of psoriasis : non-coding RNAs and cellular interactions

    Författare :Longlong Luo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Psoriasis is a prevalent immune-mediated skin disorder marked by chronically relapsing inflammation and epidermal hyperproliferation. As researchers delve deeper into the molecular intricacies of psoriasis, emerging evidence hints at the roles of non-coding RNAs (ncRNAs). LÄS MER

  5. 4. Epidemiological studies of the etiology of pancreatic cancer

    Författare :Juhua Luo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Pancreatic cancer is one of the most lethal human cancers with less than 5% of patients surviving 5 years. Despite an urgent need for primary prevention, little is known about the etiology of this cancer. This thesis was aimed at increasing our understanding of the etiology of pancreatic cancer with regard to lifestyle and infectious agents. LÄS MER

  7. 5. A genetic study on familial breast cancer predisposing genes

    Författare :Liping Luo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Breast cancer is the most common malignant disease among women in the western world and 10% of all breast cancer is assumed to constitute hereditary cases. Two major genes, BRCA1 and BRCA2, can only explain a fraction of familial breast cancer. The ATM carriers have high risk of developing breast cancer. LÄS MER
