  2. 1. A STING from a Tick : Epidemiology, Ecology and Clinical Aspects of Lyme Borreliosis

    Author : Peter Wilhelmsson; Per-Eric Lindgren; Pia Forsberg; Sven Bergström; Christina Ekerfelt; Jeremy S. Gray; Linköpings universitet; []
    Keywords : ;

    Abstract : Lyme borreliosis (LB) is the most common tick-borne disease in the Northern Hemisphere and the number of LB cases is increasing. The infection is caused by spirochetes belonging to the Borrelia burgdorferi sensu lato complex, and is, in Europe, transmitted to humans by Ixodes ricinus ticks. READ MORE

  4. 2. Scalable Queries over Log Database Collections

    Author : Minpeng Zhu; Tore Risch; Peter Gray; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap med inriktning mot databasteknik; Computer Science with specialization in Database Technology;

    Abstract : In industrial settings, machines such as trucks, hydraulic pumps, etc. are widely distributed at different geographic locations where sensors on machines produce large volumes of data. The data produced is stored locally in autonomous databases called log databases. READ MORE

  5. 3. Analysis and development of strategies for magnetic resonance functional neuroimaging

    Author : Peter Fransson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : neuroimaging; human brain; functional activation; magnetic resonance imaging; cerebral blood oxygenation;

    Abstract : This thesis focuses on strategies for oxygenation-sensitive MRI that are designed to measure alterations in brain physiology induced by changes in neuronal activity. In a first study, it was shown that the temporal evolution of BOLD MRI signal changes in response to both brief and sustained visual activation are equally well visible in FLASH and EPI recordings.

  6. 4. Neural and behavioral plasticity in olfactory sensory deprivation

    Author : Moa Peter; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The human brain has a remarkable ability to reorganize as a consequence of altered demands. This ability is particularly noticeable when studying the neural effects of complete sensory deprivation. READ MORE

  7. 5. Ultrasound Image Analysis for Automated Classification of Atherosclerotic Plaque in the Human Carotid Artery

    Author : Peter Holdfeldt; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; classification; dynamic programming; carotid artery; Java program; image segmentation; ultrasound images; intima-media thickness; atherosclerotic plaque;

    Abstract : Cardiovascular diseases, caused by atherosclerosis, is one of the most common causes of death in the industrialized world. Two risk factors, that both can be assessed with ultrasound, are the Intima-Media Thickness (IMT) in the arterial wall and the composition of the atherosclerotic plaque. READ MORE
