On the accuracy of an interdigital electrostatic position sensor
(Journal article; Peer reviewed, 2020)In this work the induced voltage in an interdigital electrode when swept by a finite, triboelectrically charged dielectric surface is investigated. Finite element modelling fits well with the measured voltage as a function ... -
On the applicability of a renormalized Born series for seismic wave modelling in strongly scattering media
(Peer reviewed; Journal article, 2020)Scattering theory is the basis for various seismic modeling and inversion methods. Conventionally, the Born series suffers from an assumption of a weak scattering and may face a convergence problem. We present an application ... -
On the Asymptotics of Solving the LWE Problem Using Coded-BKW With Sieving.
(Peer reviewed; Journal article, 2019) -
On the behavior of some APN permutations under swapping points
(Journal article; Peer reviewed, 2022)We define the pAPN-spectrum (which is a measure of how close a function is to being APN) of an (n, n)-function F and investigate how its size changes when two of the outputs of a given function F are swapped. We completely ... -
On the biogenicity of Fe-oxyhydroxide filaments in silicified low-temperature hydrothermal deposits: Implications for the identification of Fe-oxidizing bacteria in the rock record
(Peer reviewed; Journal article, 2020)Microaerophilic Fe(II)‐oxidizing bacteria produce biomineralized twisted and branched stalks, which are promising biosignatures of microbial Fe oxidation in ancient jaspers and iron formations. Extracellular Fe stalks ... -
On the Boomerang Uniformity of some Permutation Polynomials
(Journal article; Peer reviewed, 2020)The boomerang attack, introduced by Wagner in 1999, is a cryptanalysis technique against block ciphers based on differential cryptanalysis. In particular it takes into consideration two differentials, one for the upper ... -
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 chemistry, toxicology and genetics of the cyanobacterial toxins, microcystin, nodularin, saxitoxin and cylindrospermopsin
(Peer reviewed; Journal article, 2010-05-10)The cyanobacteria or “blue-green algae”, as they are commonly termed, comprise a diverse group of oxygenic photosynthetic bacteria that inhabit a wide range of aquatic and terrestrial environments, and display incredible ... -
On the Classification of Hermitian Self-Dual Additive Codes over GF(9)
(Peer reviewed; Journal article, 2012-08)Additive codes over GF(9) that are self-dual with respect to the Hermitian trace inner product have a natural application in quantum information theory, where they correspond to ternary quantum error-correcting codes. ... -
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 composite response of the MLT to major sudden stratospheric warming events with elevated stratopause
(Peer reviewed; Journal article, 2016-05)Based on a climate-chemistry model (constrained by reanalyses below ~50 km), the zonal-mean composite response of the mesosphere and lower thermosphere (MLT) to major sudden stratospheric warming events with elevated ... -
On the contribution of thermal excitation to the total 630.0 nm emissions in the northern cusp ionosphere
(Peer reviewed; Journal article, 2017-01)Direct impact excitation by precipitating electrons is believed to be the main source of 630.0 nm emissions in the cusp ionosphere. However, this paper investigates a different source, 630.0 emissions caused by thermally ... -

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 design of Neutral Scanning Helium Atom Microscopes (SHeM) : Optimal configurations and evaluation of experimental findings
(Doctoral thesis, 2021-11-09)Scanning Helium Microscopes (SHeMs) are novel microscopy tools using neutral helium atoms as the imaging probe. Helium atoms have several advantages compared to other probes such as electrons or helium ions. Helium atoms ... -
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 Dynamics and Water Mass Transformation of a Boundary Current Connecting Alpha and Beta Oceans
(Peer reviewed; Journal article, 2018-10-19)A subpolar marginal sea, like the Nordic seas, is a transition zone between the temperature-stratified subtropics (the alpha ocean) and the salinity-stratified polar regions (the beta ocean). An inflow of Atlantic Water ...
