    Background Data on the haematological outcomes of patients who continue clozapine treatment following neutropenia are very rare as even mild neutropenia results in mandatory discontinuation of clozapine in most countries. However, in Iceland where ...

    The previously reported 1-(2,4-dihydroxy-5-methylphenyl)ethan-1-one (1), (1’Z)-2-(1’,5’-dimethylhexa-1’,4’-dieny1)-5-methylbenzene-1,4-diol (2), and 1,8-epoxy-1(6),2,4,7,10-bisaborapentaen-4-ol (5) together with four new structures of aromatic ...

    A new lava field was formed at Holuhraun in the Icelandic Highlands, north of Vatnajökull glacier, in 2014–2015. It was the largest effusive eruption in Iceland for 230 years, with an estimated lava bulk volume of ~1.44 km3 covering an area of ~84 km2. ...
  • Bjarnadóttir, Kristín (2016-07-27)
    The New Math was implemented in Iceland with the intention to facilitate understanding in the midst of increased demands for education for all. The article contains an analysis and comparison of typical papers in a selective entrance examination into ...
  • Shelke, Sandip; Sandholt, Gunnar Birgir; Sigurdsson, Snorri (Royal Society of Chemistry (RSC), 2014)
    Non-covalent and site-directed spin labeling gives easy access to spin-labeled nucleic acids for the study of their structure and dynamics by electron paramagnetic resonance (EPR) spectroscopy. In a search for improved spin labels for non-covalent ...
  • Juliusson, Haraldur Y.; Sigurdsson, Snorri (Wiley, 2020-07)
    Two o‐benzoquinone derivatives of isoindoline were synthesized for use as building blocks to incorporate isoindoline nitroxides into different compounds and materials. These o‐quinones were condensed with a number of o‐phenylenediamines to form ...

    The prevalence and consequences of nasal obstruction in untreated obstructive sleep apnea patients are not known. The study objectives were to investigate the frequency of subjective and objective nasal obstruction in untreated sleep apnea patients and ...
  • Rasti, Behnood; Scheunders, Paul; Ghamisi, Pedram; Licciardi, Giorgio; Chanussot, Jocelyn (MDPI AG, 2018-03-20)
    Hyperspectral remote sensing is based on measuring the scattered and reflected electromagnetic signals from the Earth’s surface emitted by the Sun. The received radiance at the sensor is usually degraded by atmospheric effects and instrumental (sensor) ...
  • Kamble, Nilesh Ramesh; Gränz, Markus; Prisner, Thomas F.; Sigurdsson, Snorri (Royal Society of Chemistry (RSC), 2016)
    An isoindoline-nitroxide derivative of guanine (G, "G-spin") was shown to bind specifically and effectively to abasic sites in duplex RNAs. Distance measurements on a G-labeled duplex RNA with PELDOR (DEER) showed a strong orientation dependence. Thus, ...
  • Saha, Subham; Hetzke, Thilo; Prisner, Thomas F.; Sigurdsson, Snorri (Royal Society of Chemistry (RSC), 2018)
    In the first example of site-directed spin-labeling of unmodified RNA, a pyrrolidine-nitroxide derivative of tetramethylrosamine (TMR) was shown to bind with high affinity to the malachite green (MG) aptamer, as determined by continuous-wave (CW) ...
  • Kamble, Nilesh Ramesh; Wolfrum, Manpreet; Halbritter, Thomas; Sigurdsson, Snorri; Richert, Clemens (Wiley, 2020-01-21)
    Studying nucleic acids often requires labeling. Many labeling approaches require covalent bonds between the nucleic acid and the label, which complicates experimental procedures. Noncovalent labeling avoids the need for highly specific reagents and ...
  • Kravtsov, Vasily; Khestanova, Ekaterina; Benimetskiy, Fedor A.; Ivanova, Tatiana; Samusev, Anton K.; Sinev, Ivan S.; Pidgayko, Dmitry; Mozharov, Alexey M.; Mukhin, Ivan S.; Lozhkin, Maksim S.; Kapitonov, Yuri V.; Brichkin, Andrey S.; Kulakovskii, Vladimir D.; Shelykh, Ivan; Tartakovskii, Alexander I.; Walker, Paul M.; Skolnick, Maurice S.; Krizhanovskii, Dmitry N.; Iorsh, Ivan V. (Springer Science and Business Media LLC, 2020-04-09)
    Optical bound states in the continuum (BICs) provide a way to engineer very narrow resonances in photonic crystals. The extended interaction time in these systems is particularly promising for the enhancement of nonlinear optical processes and the ...
  • Giangreco Puletti, Valentina; Pourhasan, Razieh (Springer Nature, 2017-08)
    We compute holographic Rényi entropies for spherical entangling surfaces on the boundary while considering third order Lovelock gravity with negative cosmological constant in the bulk. Our study shows that third order Lovelock black holes with hyperbolic ...
  • de Boer, Jan; Hartong, Jelle; Have, Emil; Obers, Niels; Sybesma, Watse (Stichting SciPost, 2020-08-11)
    We consider uncharged fluids without any boost symmetry on an arbitrary curved background and classify all allowed transport coefficients up to first order in derivatives. We assume rotational symmetry and we use the entropy current formalism. The ...
  • Fernández, Daniel; Rajagopal, Aruna; Thorlacius, Larus (Springer Science and Business Media LLC, 2019-12-01)
    We study out-of-equilibrium energy transport in a quantum critical fluid with Lifshitz scaling symmetry following a local quench between two semi-infinite fluid reservoirs. The late time energy flow is universal and is accommodated via a steady state ...
