  2. 1. Tailoring Gaussian processes and large-scale optimisation

    Author : Carl Jidling; Thomas B. Schön; Niklas Wahlström; Adrian Wills; Lars Kai Hansen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gaussian processes; Tomographic reconstruction; Large-scale optimisation; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Abstract : This thesis is centred around Gaussian processes and large-scale optimisation, where the main contributions are presented in the included papers.Provided access to linear constraints (e.g. equilibrium conditions), we propose a constructive procedure to design the covariance function in a Gaussian process.

  6. 4. On receptor changes in cerebral arteries after subarachnoid haemorrhage

    Author : Jacob Hansen-Schwartz; Lund Medicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi; Pharmacological sciences; subarachnoid haemorrhage; reverse transcriptase polymerase chain reaction; in vitro pharmacology; organ culture; Endothelin receptors; 5-HT receptors;

    Abstract : Overall the aim has been to characterise the in vitro upregulation of the 5-hydroxytryptamine 1B/1D (5-HT(1B/1D)) and endothelin (ET) receptors in the cerebral circulation as well as demonstrating phenotypic changes in a pathophysiological model mimicking subarachnoid haemorrhage. The first part describes receptor upregulation using organ culture of whole vessel segments from both rat and man. READ MORE

  7. 5. Searches for new physics phenomena with jet final states in the ATLAS detector

    Author : Eva Brottmann Hansen; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Particle physics; jets; dark matter; Supersymmetry; Hidden Sectors; Fysicumarkivet A:2020:Brottmann;

    Abstract : Collimated sprays of paticle, known as jets,are abundantly produced in high-energy proton-proton (pp) collisions, and are predicted by many theories of physics beyond the Standard Model. This thesis reports first on the calibration of jets with focus on the data-driven in situ calibration. READ MORE
