On the Brauer group of bielliptic surfaces (with an appendix by Jonas Bergström and Sofia Tirabassi)
(Journal article; Peer reviewed, 2022)We provide explicit generators of the torsion of the second cohomology of bielliptic surfaces, and we use this to study the pullback map between the Brauer group of a bielliptic surface and that of its canonical cover. -
On the Complexity of Intersection Non-emptiness for Star-Free Language Classes
(Journal article; Peer reviewed, 2021)In the Intersection Non-emptiness problem, we are given a list of finite automata A_1, A_2,… , A_m over a common alphabet Σ as input, and the goal is to determine whether some string w ∈ Σ^* lies in the intersection of the ... -
On the Complexity of Recovering Incidence Matrices
(Journal article; Peer reviewed, 2020)The incidence matrix of a graph is a fundamental object naturally appearing in many applications, involving graphs such as social networks, communication networks, or transportation networks. Often, the data collected about ... -
On the Creation, Depletion, and End of Life of Polar Cap Patches
(Journal article; Peer reviewed, 2023)Ionospheric convection patterns from the Super Dual Auroral Radar Network are used to determine the trajectories, transit times, and decay rates of three polar cap patches from their creation in the dayside polar cap ... -
On the Distance Between APN Functions
(Journal article; Peer reviewed, 2020)We investigate the differential properties of a vectorial Boolean function G obtained by modifying an APN function F . This generalizes previous constructions where a function is modified at a few points. We characterize ... -
On the EA-classes of known APN functions in small dimensions
(Journal article; Peer reviewed, 2020)Recently Budaghyan et al. (Cryptogr. Commun. 12, 85–100, 2020) introduced a procedure for investigating if CCZ-equivalence can be more general than EA-equivalence together with inverse transformation (when applicable). In ... -
On the effect of climate trends in coastal density on deep water renewal frequency in sill fjords—A statistical approach
(Journal article; Peer reviewed, 2020)The basin water of a sill fjord is renewed intermittently, when the density of the water at sill level in the ocean outside the fjord is high enough for it to sink down to the bottom of the fjord. How often the basin water ... -
On the Effect of DCE MRI Slice Thickness and Noise on Estimated Pharmacokinetic Biomarkers – A Simulation Study
(Journal article; Peer reviewed, 2020)Simulation of a dynamic contrast-enhanced magnetic resonance imaging (DCE MRI) multiple sclerosis brain dataset is described. The simulated images in the implemented version have 1×1×1mm3 voxel resolution and arbitrary ... -
On the effect of nocturnal radiation fog on the development of the daytime convective boundary layer: A large-eddy simulation study
(Journal article; Peer reviewed, 2022)The potential effect of failing to predict nocturnal deep radiation fog on the development of the daytime convective boundary layer (CBL) is studied using large-eddy simulations. Typical spring and autumn conditions for ... -
On the effectiveness of the incremental approach to minimal chordal edge modification
(Journal article; Peer reviewed, 2021)Because edge modification problems are computationally difficult for most target graph classes, considerable attention has been devoted to inclusion-minimal edge modifications, which are usually polynomial-time computable ... -
On the formation of coastal rogue waves in water of variable depth
(Journal article; Peer reviewed, 2023)Wave transformation is an intrinsic dynamic process in coastal areas. An essential part of this process is the variation of water depth, which plays a dominant role in the propagation features of water waves, including a ... -

On the Groupiness and Intermittency of Oceanic Whitecaps
(Journal article; Peer reviewed, 2022)The enhancement of wave breaking activity during wave group passage is investigated using coherent field observations of the instantaneous sea surface elevation and whitecap coverage from platform-based stereo video ... -
On the Hardness of Generalized Domination Problems Parameterized by Mim-Width
(Journal article; Peer reviewed, 2022)For nonempty σ, ρ ⊆ ℕ, a vertex set S in a graph G is a (σ, ρ)-dominating set if for all v ∈ S, |N(v) ∩ S| ∈ σ, and for all v ∈ V(G) ⧵ S, |N(v) ∩ S| ∈ ρ. The Min/Max (σ,ρ)-Dominating Set problems ask, given a graph G and ... -
On the High‐Energy Spectral Component and Fine Time Structure of Terrestrial Gamma Ray Flashes
(Journal article; Peer reviewed, 2019)Terrestrial gamma ray flashes (TGFs) are very short bursts of gamma radiation associated to thunderstorm activity and are the manifestation of the highest‐energy natural particle acceleration phenomena occurring on Earth. ... -
On the Impact of a Streaming Oxygen Population on Collisionless Magnetic Reconnection
(Journal article; Peer reviewed, 2020)Using 2.5-D Particle-In-Cell (PIC) simulations, we investigate how magnetotail reconnection is affected by a cold, streaming, oxygen plasma population, attributed to an ionospheric source, in the inflow region. As the ... -
On the importance of parenting in externalizing disorders: an evaluation of indirect genetic effects in families
(Journal article; Peer reviewed, 2022)Background: Theoretical models of the development of childhood externalizing disorders emphasize the role of parents. Empirical studies have not been able to identify specific aspects of parental behaviors explaining a ... -
On the IND-CCA1 Security of FHE Schemes
(Journal article; Peer reviewed, 2022)Fully homomorphic encryption (FHE) is a powerful tool in cryptography that allows one to perform arbitrary computations on encrypted material without having to decrypt it first. There are numerous FHE schemes, all of which ... -
On the Influence of Sea Surface Temperature distributions on the Development of Extratropical Cyclones
(Journal article; Peer reviewed, 2021)The sea surface temperature (SST) distribution can modulate the development of extratropical cyclones through sensible and latent heat fluxes. However, the direct and indirect effects of these surface fluxes, and thus the ... -
On the Mainstream/Alternative Continuum: Mainstream Media Reactions to Right-Wing Alternative News Media
(Journal article; Peer reviewed, 2021)Using the mainstream media as a starting point, this article argues that the ongoing changes in the mainstream/alternative continuum are not just dependent on how right-wing alternative news media relate to certain ...
