    We use the IllustrisTNG (TNG) cosmological simulations to provide theoretical expectations for the dark matter mass fractions (DMFs) and circular velocity profiles of galaxies. TNG predicts flat circular velocity curves for z = 0 Milky Way (MW)-like ...

    The one-dimensional object-oriented particle-in-cell Monte Carlo collision code oopd1 is applied to explore the role of secondary electron emission and electron reflection on the properties of the capacitively-coupled oxygen discharge. At low pressure ...

    The South Iceland Seismic Zone (SISZ) accommodates E‐W translation due to oblique spreading between the North American and the Eurasian plates in South Iceland with ruptures on N‐S faults. Strain is released in earthquake sequences that last days to ...

    Fluoropyrimidine-based chemotherapy is extensively used for the treatment of solid cancers, including colorectal cancer. However, fluoropyrimidine-driven toxicities are a major problem in the management of the disease. The grade and type of the ...
  • Schellens, Marie; Gisladottir, Johanna (MDPI AG, 2018-12-01)
    Studies on critical natural resources have grown in number over the last decade out of concern for resource availability and its potential impacts. Nonetheless, only a handful of studies explicitly define criticality for natural resources. Through a ...

    We performed a series of deformation experiments on synthetic magnetite aggregates to characterize the high‐temperature rheological behavior of this mineral under nominally dry and hydrous conditions. Grain growth laws for magnetite were additionally ...

    The Harletz loess‐palaeosol sequence is located in northwestern Bulgaria and represents an important link between well‐studied loess sequences in eastern Romania and further sites to the west of the Carpathians (e.g. Serbia and Hungary). The aim of ...

    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 ...
  • 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 ...

    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 ...

    Bone area is one measure of bone size that is easily derived from dual-energy X-ray absorptiometry (DXA) scans. In a GWA study of DXA bone area of the hip and lumbar spine (N ≥ 28,954), we find thirteen independent association signals at twelve loci ...

    Swirling flow has been shown to increase heat transfer in heat exchangers. However, producing swirl while not presenting a severe pressure drop can be a challenge. In this paper, a desired shape of guidance blades for laminar swirl flow is determined ...
  • Helgadottir, Asdis; Ng, Yen Ting; Min, Chohong; Gibou, Frédéric (Elsevier BV, 2015-10)
    We consider the Poisson equation with mixed Dirichlet, Neumann and Robin boundary conditions on irregular domains. We describe a straightforward and efficient approach for imposing the mixed boundary conditions using a hybrid finite-volume/finite-difference ...

    Consistent financial reward of particular features influences the allocation of visual attention in many ways. More surprising are 1-trial reward priming effects on attention where reward schedules are random and reward on one trial influences attentional ...

    Grapheme-color synesthesia is a condition where the perception of graphemes consistently and automatically evokes an experience of non-physical color. Many have studied how synesthesia affects the processing of achromatic graphemes, but less is known ...

    Dynamic sitting, such as fidgeting and desk work, might be associated with health, but remains difficult toidentify out of accelerometry data. We examined, in a laboratory study, whether dynamic sitting can beidentified out of triaxial activity counts. ...

    Í greininni er litið yfir höfundarverk Jakobínu Sigurðardóttur á aldarafmæli hennar og rýnt í ýmsa þætti í skáldsögum hennar, smásögum, ljóðum og æskuminningum. Hugað er að því hvernig höfundurinn sviðsetur tímann í textum sínum – tímann í æviskeiðinu ...

    Þórarinn B. Þorláksson (1867–1924) hefur verið talinn sá fyrsti sem starfaði sem listmálari á Íslandi. Þær viðtökur sem list hans hlaut, bæði heima við og í útlöndum, er áhugaverð sýn á breytt viðhorf og hugmyndafræðilega afstöðu til íslenskrar ...

    Fjallað er um skáldsöguna Kötu eftir Steinar Braga og í fyrstu eru greinafræðilegar eigindir skáldsögunnar dregnar fram og hún sett í samhengi við þá tegund samtímalegra glæpasagna er setja samfélagsrýni á oddinn. Bent er þó á að skáldsagan gangi ...
  • Þórhallsdóttir, Guðrún (Hugvísindastofnun Háskóla Íslands, 2018-12-20)
    Í greininni er fjallað um sögu nafnorðanna gleðimaður, sem þekkt er úr íslensku máli að fornu og nýju, og gleðikona sem birtist fyrst í heimild frá 18. öld. Auk þess er sagt frá fleiri samsettum orðum með gleði- sem fyrri lið sem hafa verið notuð um ...
