  1. 11. Left Ventricular Systolic Dysfunction in 75-year-old Men and Women : A Community-based Study of Prevalence, Screening and Mitral Annulus Motion for Diagnosis and Prognostics

    Författare :Pär Hedberg; Tommy Jonason; Ivar Ringqvist; Eva Nylander; Uppsala universitet; []
    Nyckelord :Medical sciences; Aged; Heart Failure; Ventricular Function; Prevalence; Echocardiography; Electrocardiography; Natriuretic Peptide; Mortality; MEDICIN OCH VÅRD; MEDICINE; MEDICIN;

    Sammanfattning : Reduced performance of the left ventricle to eject blood – left ventricular systolic dysfunction (LVSD) – is a common predecessor of the heart failure syndrome. With or without symptoms, LVSD is associated with a poor prognosis. LÄS MER

  3. 12. Hybrid digital twins: A co-creation of data science and physics

    Författare :Antonio Galvez; Diego Galar; Uday Kumar; Dammika Seneviratne; Dimitrios Kyritsis; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid modelling; physics-based model; data-driven model; HVAC system; Railway; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Safety is more important than reliability or efficiency in railway, aerospace, oil & gas, and chemical industries. Regulations are very restrictive in sectors where safety is paramount. LÄS MER

  4. 13. Enablement of digital twins for railway overhead catenary system

    Författare :Amit Patwardhan; Ramin Karim; Rikard Granström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway catenary; Maintenance; eMaintenance; LiDAR; Point Cloud; Digital Twin; Software Architecture; Drift och underhållsteknik; Operation and Maintenance;

    Sammanfattning : Railway has the potential to become one of the most sustainable mediums for passenger and freight transport. This is possible by continuous updates to the asset management regime supporting Prognostics and Health Management (PHM). Railway tracks and catenaries are linear assets, and their length plays a vital role in maintenance. LÄS MER

  5. 14. Hippocampal volumetry in mild cognitive impairment

    Författare :Carl Eckerström; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mild cognitive impairment; dementia; Alzheimer s disease; vascular dementia; MRI; hippocampus; white matter lesions; CFS biomarkers; neuropsychology;

    Sammanfattning : Dementia is a syndrome with cognitive decline as a prominent feature. MCI is similarly a syndrome of cognitive decline, albeit with much subtler symptoms, and has been identified as a condition at risk for progression to dementia. A considerable clinical challenge lies in identifying MCI patients with an underlying dementia disorder. LÄS MER

  7. 15. Proteomics of invasiveness of human breast epithelial cells

    Författare :Kah Wai Lin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mechanisms of malignant transformation and cancer invasion and factors controlling them in response to various stimuli remain elusive. We used proteomics and systems biology to explore these mechanisms in human breast epithelial cells. The objective has been to identify a set of biomarkers for diagnostics and prognostics of breast cancer. LÄS MER
