    Objective To test the hypothesis that age-related macular degeneration (AMD) and retinal microvascular signs are differentially associated with lobar and deep cerebral microbleeds (CMBs). Methods CMBs in lobar regions indicate cerebral amyloid ...

    Northern freshwater fish may be suitable for the genetic dissection of ecological traits because they invaded new habitats after the last ice age (∼10.000 years ago). Arctic charr (Salvelinus alpinus) colonizing streams and lakes in Iceland gave rise ...

    The long term side effects of any newly introduced drug is a subject of intense research, and often raging controversies. One such example is the dipeptidyl peptidase-IV (DPP4) inhibitor used for treating type 2 diabetes, which is inconclusively ...
  • Monger, Lindsey J.; Runarsdottir, Gerdur R.; Suman, Sigridur G (Springer Science and Business Media LLC, 2020-07-16)
    Alkylation of the C-terminus acids in small peptides allows direction to amine and amide coordination, while changing the peptide composition to form tetradentate κ4[n,5,5], where n = 5-, 6-, 7-, or 8-membered ring coordination geometries, can be ...

    There is a growing body of evidence demonstrating the impacts of human arrival in new “pristine” environments, including terrestrial habitat alterations and species extinctions. However, the effects of marine resource utilization prior to industrialized ...

    This article investigates the implementation of disaster risk reduction education for children in Indonesia. In the last decade, education programmes related to this subject have been promoted as capable of reducing disaster losses and increasing ...
  • Saavedra, Jose M; Þorgeirsson, Sveinn; Chang, Milan; Kristjansdottir, Hafrún; García-Hermoso, Antonio (Walter de Gruyter GmbH, 2018-06-13)
    Sports performance analysis has been a growing field of study in the last decade. However, the number of studies in handball is small. The aims of this present study were (i) to compare handball game-related statistics by the match outcome (winning and ...
  • Hyytia, Esa; Righter, Rhonda; Bilenne, Olivier; Wu, Xiaohu (Elsevier BV, 2017-09)
    We study the M/D/1 queue when jobs have firm deadlines for waiting (or sojourn) time. If a deadline is not met, a job-specific deadline violation cost is incurred. We derive explicit value functions for this M/D/1 queue that enable the development of ...

    Motivated by the use of tetrakis(dimethylamino)silane (TKDMAS) to produce silicon nitride-based deposits and its potential as a precursor for Focused Electron Beam Induced Deposition (FEBID), we have studied its reactivity towards low energy electrons ...
