    Hyperhidrosis is characterized by excessive sweating beyond thermoregulatory needs that affects patients' quality of life. It results from an excessive stimulation of eccrine sweat glands in the skin by the sympathetic nervous system. Hyperhidrosis may ...

    In this paper, we develop a hyperspectral feature extraction method called sparse and smooth low-rank analysis (SSLRA). First, we propose a new low-rank model for hyperspectral images (HSIs) where we decompose the HSI into smooth and sparse components. ...
  • Zhao, Bin (University of Iceland, School of Engineering and Natural Sciences, Faculty of Electrical and Computer Engineering, 2021-12-16)
    Hyperspectral images (HSIs) acquired by hyperspectral imaging sensors contain hundreds of spectral bands. The abundant spectral information provided by an HSI makes it possible to discriminate different materials in a scene. Therefore, HSIs have ...

    Hyperspectral image (HSI) is usually corrupted by various types of noise, including Gaussian noise, impulse noise, stripes, deadlines, and so on. Recently, sparse and low-rank matrix decomposition (SLRMD) has demonstrated to be an effective tool in ...
  • Palsson, Burkni; Sigurdsson, Jakob; Sveinsson, Jóhannes Rúnar; Ulfarsson, Magnus (Institute of Electrical and Electronics Engineers (IEEE), 2018)
    In this paper, we present a deep learning based method for blind hyperspectral unmixing in the form of a neural network autoencoder. We show that the linear mixture model implicitly puts certain architectural constraints on the network, and it effectively ...

    Objective The myosin-binding protein C (MYBPC3) c.927-2A>G founder mutation accounts for >90% of sarcomeric hypertrophic cardiomyopathy (HCM) in Iceland. This cross-sectional observational study explored the penetrance and phenotypic burden among ...

    Background: The debate whether "asymptomatic hyperuricemia" should be treated is still ongoing. The objective of this cross-sectional study was to analyze whether hyperuricema in the elderly is associated with joint pain. Methods and findings: Participants ...

    Þegar komið er yfir 2500 m hæð yfir sjávarmáli geta einkenni hæðarveiki gert vart við sig innan nokkurra daga. Áhættan ræðst einkum af hæð og hraða hækkunar og einkennin eru fjölbreytt. Háfjallaveiki er langalgengust en lífshættulegur hæðarheilabjúgur ...
  • Beck, Sigríður (Institutionen för historiska studier, Göteborgs universitet, 2011)
    Icelandic society was transformed during the 13th century. There was no kingdom in Iceland until 1262/1264, when the Norwegian kingship annexed the country. Along with the kingship a new political system, with new rules and ways to acquire power, ...
  • Gunnlaugsson, Geir; Einarsdóttir, Jónína (Informa UK Limited, 2018-10-18)
    The monitoring of relevant health indicators is important in the examination of work that aims to improve health, not only globally, as for example, through the Millennium Development Goals 2000–2015, but also at the national, regional and/or sectoral, ...
  • Gunnlaugsson, Geir; Sigurðardóttir, Þórdís; Einarsdóttir, Margrét; Einarsdóttir, Jónína (Cambridge Scholars Publishing, 2018)
    Iceland came under the jurisdiction of the Norwegian King in 1262 to later become a colony of Denmark for about 500 years. Already in the second half of the 18th century, the Danish king initiated actions that aimed to improve the precarious situation ...
  • Hilmarsson, Hilmar Þór (2014)
    The 2008 global economic and financial crisis hit hard in Iceland and Latvia. Economic developments prior to the crisis, as well as response to the crisis were, however, different in these two countries, yielding different results. Both countries ...

    Highly pathogenic avian influenza viruses (HPAIVs) of hemagglutinin type H5 and clade 2.3.4.4b have widely spread within the northern hemisphere since 2020 and threaten wild bird populations, as well as poultry production. We present phylogeographic ...
  • Bjarnason, Ingi Þorleifur (Iceland Glaciological Society and Geoscience Society of IcelandJöklarannsóknafélags Íslands og Jarðfræðafélags Íslands, 2008)
    Is Iceland a hotspot, with ridge-centered plume? In Iceland vigorous volcanism has built up a plateau 3.0 km higher than at a normal mid-ocean ridge with 3 to 4 times thicker crust than average oceanic crust. This volcanism can be associated with ...
