  1. 1. Mitigation of nonlinear fiber distortion using phase conjugation

    Författare :Henrik Eliasson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber-optic communication; nonlinear optics; phase conjugation; phase-sensitive amplifiers;

    Sammanfattning : This thesis is devoted to the study of fiber-optic communication systems that mitigate nonlinear distortion due to the Kerr effect by transmitting a phase-conjugated copy alongside the signal followed by coherent superposition. This kind of communication systems are referred to as phase-conjugated twin waves systems when the phase-conjugated copy is transmitted on the orthogonal polarization. LÄS MER

    Sammanfattning : Over the last decade environmental agencies worldwide have escalated their work to phase out animal testing for the purposes of chemical regulation. Meanwhile the number of commercially available chemicals and the requirements for hazard assessments have both increased, creating a large need for substitution of traditional in vivo assays with in vitro tests.

  4. 3. Solid-phase Proximity Ligation Assays : High-performance and multiplex protein analyses

    Författare :Spyros Darmanis; Masood Kamali-Moghaddam; Ulf Landegren; Mathias Uhlen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; proximity ligation assay; multiplexed; biomarkers; solid-phase; microparticles; cancer; sequencing; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Biotechnology; Biologi med inriktning mot molekylär bioteknik;

    Sammanfattning : Protein biomarkers circulating in blood hold the promise of improved diagnosis, prognosis and follow-up of treatment of disease via minimally invasive procedures. For the discovery and validation of such biomarkers, methods are needed that can facilitate parallel, highly specific and in-depth analysis of the blood proteome. LÄS MER

  5. 4. Optical Phase Conjugation and All-Optical Demultiplexing using Four-Wave Mixing in Dispersion Shifted Fibers

    Författare :Per Olof E Hedekvist; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dispersion compensation; nonlinear fiber optics; high-speed communication; four-wave mixing; parametric amplification; noise figure; wavelength conversion; optical phase conjugation; all-optical demultiplexer; mid-span spectral inversion;

    Sammanfattning : This thesis deals with two applications of four-wave mixing in optical dispersion-shifted fibers; optical phase conjugation and all-optical switching. The work is a part of an effort to study the upgradability of the existing fiber plant, which is of large economic interest. LÄS MER

  7. 5. Investigations of chemical and enzymatic functionalization of affinity proteins

    Författare :Anders Myrhammar; Amelie Eriksson Karlström; Per-Åke Nygren; Christian Heinis; KTH; []
    Nyckelord :Affinity protein; affibody; conjugation; solid phase peptide synthesis; proteolytic stability; peptide nucleic acid PNA .; Bioteknologi; Biotechnology;

    Sammanfattning : AbstractAffinity proteins are important reagents in research, diagnostics and therapeutic settings. The focus of this thesis has been on investigating different chemical and enzymatic strategies for engineering of affinity proteins to generate affinity reagents with improved or changed functionality.
