    Sammanfattning : Human activity recognition using sensing technology is crucial in achieving pervasive and ubiquitous computing paradigms. It can be applied in many domains such as health-care, aged-care, personal-informatics, industry, sports and military. LÄS MER

  4. 3. Origin and the evolution of diatoms through the integration of paleontology and phylogenetics

    Författare :Karolina Brylka; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diatoms; evolution; fossil record; Cretaceous; molecular evolution; Mesozoic; silicon transporter proteins; gene duplication;

    Sammanfattning : Diatoms, the prominent photosynthetic eucaryotes, have inhabited the world’s oceans for at least the past 120 Ma since their first appearance in the Lower Cretaceous. There are also records of older diatoms, from the Jurassic dating to ca. 172 Ma and ca. 165 Ma, however these are poorly documented. LÄS MER

  5. 4. Intracerebral hemorrhage in patients treated with intravenous thrombolysis for acute ischemic stroke

    Författare :Michael V Mazya; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background. Nearly 30000 people suffer a stroke in Sweden every year. Stroke is the third most common cause of death after heart disease and cancer carrying a 17% mortality rate at three months. It is the most common cause of neurological disability in adults. LÄS MER

  7. 5. Exploring openEHR-based clinical guidelines in acute stroke care and research

    Författare :Nadim Anani; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Largely speaking, health information systems today are not able to exchange data between each other and understand the data’s meaning automatically by means of their information technology components. This lack of ‘interoperability’ also leads to patients experiencing an undesired discontinuity in their care. LÄS MER
