  1. 1. Deep Learning for Active Fire Detection Using Multi-Source Satellite Image Time Series

    Författare :Yu Zhao; Yifang Ban; Andrea Nascetti; Josephine Sullivan; Cartalis Constantinos; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wildfire; Remote Sensing; Active Fire Detection; GOES-R ABI; Suomi-NPP VIIRS; Image Segmentation; Deep Learning; Gated Recurrent Units GRU ; Transformer.; Vilda Bränder; Fjärranalys; Aktiv Branddetektering; GOES- R ABI; Suomi-NPP VIIRS; Bildsegmentering; Djupinlärning; Gated Recurrent Units GRU ; Transformer; Geoinformatik; Geoinformatics;

    Sammanfattning : In recent years, climate change and human activities have caused increas- ing numbers of wildfires. Earth observation data with various spatial and temporal resolutions have shown great potential in detecting and monitoring wildfires. LÄS MER

  3. 2. Thiyl radicals, reaction kinetics and redox chemistry

    Författare :Rong Zhao; KTH; []
    Nyckelord :;

    Sammanfattning : In focusing on the free radical chemistry of thiyl radicals,two importantclasses are dealt with, namely, the amino acidalkylthiyl and the acylthiyl radicals, where pulse radiolysisand steady state γ-radiolysis are applied.Amino acid thiyl radicals (RS•), are important in manybiological systems,as intermediates in the repair reactions ofthiols towards targeted carbon-centeredradicals and ascatalytic centers in many enzymatic reactions.

  4. 3. Bloody big data : ensuring the health of blood donors and transfused patients with health registers

    Författare :Jingcheng Zhao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Blood transfusion is widely considered a pillar of modern medicine and is one of the most common medical interventions. A transfusion intimately links two persons and their health through the altruism of blood donors. In turn, this has necessitated the development of rigorous safety measures for both donors and recipients. LÄS MER

  5. 4. Effect of valve replacement for aortic stenosis on ventricular function

    Författare :Ying Zhao; Michael Henein; Per Lindqvist; Eugenio Picano; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; aortic valve replacement; echocardiography; speckle tracking; exercise echocardiography; ventricular function; septal radial motion; twist; displacement; strain; strain rate;

    Sammanfattning : Background：Aortic stenosis (AS) is the commonest valve disease in the West. Aortic valve replacement (AVR) remains the only available management for AS and results in improved symptoms and recovery of ventricular functions. LÄS MER

  7. 5. Allergic airway inflammation and bone marrow eosinophilopoiesis. Modulation by cytokines

    Författare :Lin-Ling Zhao; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; allergy; airway inflammation; cytokine; eosinophil; eosinophilopoiesis;

    Sammanfattning : Accumulation of eosinophils in the airways and lung parenchyma is one of the hallmarks of allergic airway inflammation. This cellular inflammatory response is likely to involve the release of eosinophils from peripheral storage pools and possibly cause production of eosinophils in the bone marrow (BM). LÄS MER
