  1. 21. Towards Single-Ion Detection and Single-Photon Storage in Rare-Earth-Ion-Doped Crystals

    Författare :Mohammed Alqedra; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Single-ion detection; microcavities; quantum memory; rare-earth-ion-doped crystals; Fysicumarkivet A:2022:Alqedra;

    Sammanfattning : Solid materials doped with rare-earth ions are considered an attractive platform for quantum information applications. One of the main reasons for this is the exceptionally long optical and hyperfine coherence times of the 4fn states, due to the shielding provided by the outer lying 5s and 5p electrons. LÄS MER

  3. 22. Finding order in chaos : Dissecting single-cell heterogeneity in space and time

    Författare :Christian Gnann; Emma Lundberg; Manuel D Leonetti; Lucas Pelkmans; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; non-genetic single-cell heterogeneity; cell cycle; metabolism; imaging-based subcellular proteomics; phosphoproteomics; icke-genetisk single-cell heterogenitet; cellcykel; metabolism; bildbaserad subcellulär proteomik; fosfoproteomik; Biotechnology; Bioteknologi;

    Sammanfattning : The cell is the smallest unit of life and contains DNA, RNA, proteins and a variety of other macromolecules. In recent years, technological advances in the field of single cell biology have revealed a staggering amount of phenotypic heterogeneity between cells in a population, which were previously considered homogenous.

  4. 23. Causes and consequences of individual variation in anti-predator traits

    Författare :Kaj Hulthén; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal migration; partial migration; individual differences; predator; personality trait; phenotypic plasticity; inducible defence; mortality risk;

    Sammanfattning : Predation imposes a potent evolutionary force on prey, moulding the evolution of traits and diversification of species, and can furthermore have powerful ecological consequences. We know that different species vary in how they cope with their natural enemies, and, consequently, a huge range of anti-predator defences are displayed in nature. LÄS MER

  5. 24. Single-molecule Detection in situ

    Författare :Chatarina Larsson; Mats Nilsson; Ulf Landegren; Sanjay Tyagi; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Molecular medicine; Molekylär medicin; Molecular Medicine; molekylär medicin genetik och patologi ;

    Sammanfattning : The human body contains a variety of different cell types that share a common genome, but differ in how they use the information encoded therein. Variation in molecular content exists even at the level of individual cells, and to provide deeper insight into complex cellular processes methods that permit analysis of each cell on its own are needed.

  7. 25. Statistical processing of Flash X-ray Imaging of protein complexes

    Författare :Alberto Pietrini; Carl Nettelblad; Johan Bielecki; Janos Hajdu; Flavio Capotondi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray; XFEL; single particle; hit-finder; statistical hit-finder; single protein; protein complex; RNA polymerase II; FEL; free-electron laser; FXI; Flash X-ray Imaging; CXI; CSPAD; x-ray imaging; COACS; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Sammanfattning : Flash X-ray Imaging (FXI) at X-ray Free Electron Lasers (XFELs) is a promising technique that permits the investigation of the 3D structure of molecules without the need for crystallization, by diffracting on single individual sample particles.In the past few years, some success has been achieved by using FXI on quite large biological complexes (40 nm-1 μm in diameter size).
