  2. 1. Automatic Virus Identification using TEM : Image Segmentation and Texture Analysis

    Author : Gustaf Kylberg; Ida-Maria Sintorn; Gunilla Borgefors; Walter Kropatsch; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; image analysis; image processing; virus identification; transmission electron microscopy; texture analysis; texture descriptors; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Viruses and their morphology have been detected and studied with electron microscopy (EM) since the end of the 1930s. The technique has been vital for the discovery of new viruses and in establishing the virus taxonomy. Today, electron microscopy is an important technique in clinical diagnostics. READ MORE

  4. 2. Uncertainties in Neural Networks : A System Identification Approach

    Author : Magnus Malmström; Fredrik Gustafsson; Isaac Skog; Daniel Axehill; Håkan Hjalmarsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neural networks; uncertainty; system identification;

    Abstract : In science, technology, and engineering, creating models of the environment to predict future events has always been a key component. The models could be everything from how the friction of a tire depends on the wheels slip  to how a pathogen is spread throughout society. READ MORE

  5. 3. Implications of Local Puumala Hantavirus Genetics and Epidemiology for Diagnostics and Vaccine Development

    Author : Patrik Johansson; Fredrik Elgh; Göran Bucht; Detlev Krüger; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Communicable diseases; hantavirus; Puumala virus; nephropathia epidemica; genome sequence; glycosylation; linear DNA vaccine; microarray; identification; genetic variability; Infektionssjukdomar; Infectious diseases; Infektionssjukdomar; medicinsk virologi; Medical Virology;

    Abstract : Puumala viruses, a member of the Hantavirus genus in the Bunyaviridae family, are enveloped by a lipid bilayer and possesses a tripartite single stranded RNA genome with negative polarity. The hantaviruses encode four proteins: a nucleocapsid protein (N), two membrane spanning glycoproteins (GN and GC) and a RNA dependent RNA polymerase (RdRp). READ MORE

  6. 4. Clearing up Culex Confusion : A Basis for Virus Vector Discrimination in Europe

    Author : Jenny C. Hesson; Jan O. Lundström; Örjan Östman; Åke Lundkvist; Anssi Laurila; Laura D Kramer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Culex torrentium; Culex pipiens; mosquitoes; vector; ornithophilic; Sindbis virus; West Nile virus; Populationsbiologi; Population Biology;

    Abstract : Mosquito species of the Culex genus are the enzootic vectors for several bird-associated viruses that cause disease in humans. In Europe, these viruses include Sindbis (SINV), West Nile and Usutu viruses. The morphologically similar females of Cx. torrentium and Cx. READ MORE

  7. 5. Identification and evaluation of antiviral compounds targeting Rift Valley fever virus

    Author : Koushikul Islam; Clas Ahlm; Magnus Evander; Anna K. Överby; Johan Neyts; Umeå universitet; []
    Keywords : Rift Valley fever virus; antiviral; assay development; screening; drug discovery;

    Abstract : Rift Valley fever virus (RVFV), a negative-stranded RNA virus, is the etiological agent of the vector-borne zoonotic disease Rift Valley fever (RVF). RVFV causes significant morbidity and mortality in humans and livestock throughout Africa and the Arabian Peninsula. READ MORE
