    Background: More than 500 million people worldwide live within exposure range of an active volcano and children are a vulnerable subgroup of such exposed populations. However, studies on the effects of volcanic eruptions on children’s health beyond the ...
  • Iordache, Paul (2019-02)
    In Romania, there is a lack of quantitative data associating cancer risk with genetic characteristics. The aim of this thesis is to evaluate genetic risk factors associated with two major cancer types, prostate cancer and colorectal cancer. The first ...
  • Magnúsdóttir, Eydís Huld (2019-02)
    Monitoring cognitive workload has the potential to improve both performance and fidelity of individuals facing safety-critical situations in their working environments. Psychophysiological signals, in particular from speech and the cardiovascular system, ...
  • Perkin, Samuel (2018-02)
    Power system operation is concerned with supplying electricity to society in a reliable manner. Reliability has traditionally been managed through use of the deterministic N-1 criterion. The EU FP7 GARPUR research project proposes that Transmission ...
  • Edmunds, Kyle (2017-06)
    The growing field of translational myology continually seeks to define and promote the generalizability of muscle research to clinical practice via optimizing the transition of a wide variety of investigative muscle assessment modalities. There are ...
  • Brown, Adam R.; Gharibyan, Hrant; Streicher, Alexandre; Susskind, Leonard; Thorlacius, Larus; Zhao, Ying (American Physical Society (APS), 2018-12-28)
    The growth of the “size” of operators is an important diagnostic of quantum chaos. Susskind conjectured that the holographic dual of the size is proportional to the average radial component of the momentum of the particle created by the operator. Thus ...

    Current efficiency loss in aluminum electrolysis happens due to a variety of factors. One such factor is the presence of impurities. Concerns about impurities have been voiced since the quality of raw materials has declined and dry-scrubbers were ...
  • Ilkov, Marjan (2016-02)
    Space-charge limited emission in vacuum microdiodes can go through transverse modulation under certain conditions. The frequency of this modulated current is in the terahertz band and it can be tuned by changing either the the gap spacing or the gap ...

    Liquid dominated reservoirs are a common type of hydrothermal reservoirs. They consist of fractured rock and reservoir fluid which may obey Darcy’s law. Steam can form in such reservoirs either through heat input which causes temperature increase or ...

    Pneumococci are commonly carried asymptomatically in the nasopharynx, especially in children. Pneumococci are also one of the major bacterial pathogens causing both severe infections and non-severe infections in both children and adults. The most severe ...

    Transcriptional regulatory mechanisms drive the maturation of B cells to plasma cells, with a dramatic transcriptional rewiring taking place during the transition. This rewiring is dependent on a number of factors, including the transcription factor B ...
  • Khamespanah, Ehsan (2018-06)
    In the recent years, formal modeling and verification of realtime systems have become very important. Difficult-to-use modeling languages and inefficient analysis tools are the main obstacles to use formal methods in this domain. Timed actor model is ...
  • Bean, Christian (2018-06)
    New automatic methods for enumerating permutation classes are introduced. The first is Struct, which is an algorithm that conjectures a structural description using rules similar to generalized grid classes. These conjectured structural descriptions ...
  • Sich, Maksym; Tapia-Rodriguez, Lucy E.; Sigurdsson, Helgi; Walker, Paul M.; Clarke, Edmund; Shelykh, Ivan; Royall, Benjamin; Sedov, Evgeny S.; Kavokin, Alexey V.; Skryabin, Dmitry V.; Skolnick, Maurice S.; Krizhanovskii, Dmitry N. (American Chemical Society (ACS), 2018-11-12)
    We report stable orthogonally polarized domains in high-density polariton solitons propagating in a semiconductor microcavity wire. This effect arises from spin-dependent polariton–polariton interactions and pump-induced imbalance of polariton spin ...

    High-temperature geothermal wells are drilled in stages and constructed of several concentric steel casings that are cemented over their entire external surface for sealing and structural support purposes. The structural integrity of such casings is ...
  • Chauhan, Vijay (2019-05-28)
    Superheated steam from high enthalpy vapor dominated geothermal fields offers an opportunity to extract greater exergy per unit flow with higher thermodynamic output efficiency compared to conventional geothermal wells. The first full scale well drilled ...
  • Eyþórsson, Elías (University of Iceland, School of Health Sciences, Faculty of Medicine, 2019-06-05)
    Streptococcus pneumoniae is a Gram-positive diplococcus that is both a commensal bacterium in the upper respiratory tract of humans, and a common pathogen. The infectious manifestations of pneumococci span a range from benign to serious; from acute ...
  • Ali, Jafari (2016-06)
    This dissertation is composed of two parts. In the first part, performance evaluation and verification of safety properties are provided for real-time actors. Recently, the actor-based language, Timed Rebeca, was introduced to model distributed and ...
  • Lejsek, Herwig (2016-02)
    This thesis presents the NV-tree (Nearest Vector tree), which addresses thespecific problem of efficiently and effectively finding the approximatek-nearest neighbors within large collections of high-dimensional data points.The NV-tree is a very ...
