  1. 6. Discussions on Dai-Freed Anomalies

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Huaiyu Li; [2019]
    Nyckelord :Anomaly; Quantum Fields Theory; Dai-Freed Theorem; Topology;

    Sammanfattning : In both field theories of high energy physics and field theories of condensed matter theories anomalies have been imposing constraints and bringing up new theories. While the perturbational and local anomalies from triangle diagrams are well-developed, we follow and review two works leading to non-perturbational global anomalies both related with Atiyah-Patogi-Sieger (APS) index theorem.

  3. 7. Molecular characterization of soil-borne viruses infecting sugar beet in Europe and USA

    Uppsats för yrkesexamina på avancerad nivå, SLU/Department of Plant Biology (from 140101)

    Författare :Efstratia Poimenopoulou; [2017]
    Nyckelord :beet necrotic yellow vein virus; beet soil-borne mosaic virus; beet soil-borne virus; beet virus Q; benyvirus; PCR; Polymyxa betae; pomovirus; RNA virus;

    Sammanfattning : Beet necrotic yellow vein virus (BNYVV, Benyvirus) is the causal agent of rhizomania disease. BNYVV and Beet soil-borne mosaic virus (BSBMV, Benyvirus) share high similarity in their genome organisation. LÄS MER

  4. 8. Effect of additional compression features on h.264 surveillance video

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för informationssystem och -teknologi

    Författare :Erik Comstedt; [2017]
    Nyckelord :Video stream; compression; frame rate; GOP; surveillance;

    Sammanfattning : In video surveillance business, a recurring topic of discussion is quality versus data usage. A higher quality allows for more details to be captured at the cost of a higher bit rate, and for cameras monitoring events 24 hours a day, limiting data usage can quickly become a factor to consider.

  5. 9. Sequence analyses of novel Potato virus YNTN and resistance-breaking PVYO isolates from Sweden

    Magister-uppsats, SLU/Department of Plant Biology (from 140101)

    Författare :Asmaa Youssef; [2017]
    Nyckelord :defective RNA molecules; D-RNAs; phylogeny; potato tuber necrotic ringspot disease; potyvirus; PVYNTN; PVY strains; recombination;

    Sammanfattning : Potato virus Y (PVY) is a devastating potato pathogen affecting potato (Solanum tuberosum) production worldwide. In the last few decades, novel PVY recombinant genotypes have been described to induce severe symptoms in numerous potato cultivars. LÄS MER

  7. 10. Sensitivity of Various Qubit Detection Methods in Pr:Y2SiO5

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Författare :Vassily Kornienko; [2017]
    Nyckelord :Rare-earth ion quantum computing; Pr:Y2SiO5; Physics and Astronomy;

    Sammanfattning : The long coherence times of the 4f hyperfine levels of rare-earth-ions gives the possibility to use these as quantum computation devices. Moreover after being doped into a crystal the strong dipole-dipole interaction can be utilized to entangle them. Much work has been done here in Lund to attain as many of the DiVincenzo criteria as possible. LÄS MER
