Simultaneous conduction and valence band quantisation in ultra-shallow, high density doping profiles in semiconductors
F. Mazzola, J. W. Wells, A. C. Pakpour-Tabrizi +4
We demonstrate simultaneous quantisation of conduction band (CB) and valence band (VB) states in silicon using ultra-shallow, high density, phosphorus doping profiles (so-called Si…
A Systematic Mapping Study on Requirements Engineering in Software Ecosystems
Aparna Vegendla, Anh Nguyen Duc, Shang Gao +1
Software ecosystems (SECOs) and open innovation processes have been claimed as a way forward for the software industry. A proper understanding of requirements is as important for t…
On Gabor orthonormal bases over finite prime fields
A. Iosevich, M. Kolountzakis, Yu. Lyubarskii +2
We study Gabor orthonormal windows in for translation and modulation sets and , respectively, where is prime and . We prove that for a set $…
What is a post-Lie algebra and why is it useful in geometric integration
Charles Curry, Kurusch Ebrahimi-Fard, Hans Munthe-Kaas
We explain the notion of a post-Lie algebra and outline its role in the theory of Lie group integrators.
The scattering of a scalar beam from isotropic and anisotropic two-dimensional randomly rough Dirichlet or Neumann surfaces: The full angular intensity distributions
Torstein Storflor Hegge, Torstein Nesse, Alexei A. Maradudin +1
By the use of Green's second integral identity we determine the field scattered from a two-dimensional randomly rough isotropic or anisotropic Dirichlet or Neumann surface when it…
A Deep Network Model for Paraphrase Detection in Short Text Messages
Basant Agarwal, Heri Ramampiaro, Helge Langseth +1
This paper is concerned with paraphrase detection. The ability to detect similar sentences written in natural language is crucial for several applications, such as text mining, tex…
The transition in settling velocity of surfactant-covered droplets from the Stokes to the Hadamard-Rybczynski solution
Åsmund Ervik, Erik Bjørklund
The exact solution for a small falling drop is a classical result by Hadamard and Rybczynski. But experiments show that small drops fall slower than predicted, giving closer agreem…
Coopetition of software firms in Open source software ecosystems
Anh Nguyen Duc, Daniela S. Cruzes, Geir K. Hanssen +2
Software firms participate in an ecosystem as a part of their innovation strategy to extend value creation beyond the firms boundary. Participation in an open and independent envir…
Towards understanding startup product development as effectual entrepreneurial behaviors
Anh Nguven Duc, Yngve Dahle, Martin Steinert +1
Software startups face with multiple technical and business challenges, which could make the startup journey longer, or even become a failure. Little is known about entrepreneurial…
-abelian quotients of -angulated categories
Karin M. Jacobsen, Peter Jorgensen
Let be a triangulated category. If is a cluster tilting object and is the ideal of morphisms factoring through an object of $\oper…
Field-free nucleation of antivortices and giant vortices in non-superconducting materials
Morten Amundsen, Jabir Ali Ouassou, Jacob Linder
Giant vortices with higher phase-winding than are usually energetically unfavorable, but geometric symmetry constraints on a superconductor in a magnetic field are known to st…
High-energy neutrinos from Galactic superbubbles
K. J. Andersen, M. Kachelriess, D. V. Semikoz
We study the propagation of cosmic rays generated by sources residing inside superbubbles. We show that the enhanced magnetic field in the bubble wall leads to an increase of the i…
Wave scattering from two-dimensional self-affine Dirichlet and Neumann surfaces and its application to the retrieval of self-affine parameters
Daniel Strand, Torstein Nesse, Jacob B. Kryvi +2
Wave scattering from two-dimensional self-affine Dirichlet and Neumann surfaces is studied for the purpose of using the intensity scattered from them to obtain the Hurst exponent a…
Influence of surfactants on the electrohydrodynamic stretching of water drops in oil
Åsmund Ervik, Torstein Eidsnes Penne, Svein Magne Hellesø +2
In this paper we present experimental and numerical studies of the electrohydrodynamic stretching of a sub-millimetre-sized salt water drop, immersed in oil with added non-ionic su…
Overview of (pro-)Lie group structures on Hopf algebra character groups
Geir Bogfjellmo, Rafael Dahmen, Alexander Schmeding
Character groups of Hopf algebras appear in a variety of mathematical and physical contexts. To name just a few, they arise in non-commutative geometry, renormalisation of quantum…
Approximate dispersion relations for waves on arbitrary shear flows
Simen Å. Ellingsen, Yan Li
An approximate dispersion relation is derived and presented for linear surface waves atop a shear current whose magnitude and direction can vary arbitrarily with depth. The approxi…
Post-Lie Algebras, Factorization Theorems and Isospectral-Flows
Kurusch Ebrahimi-Fard, Igor Mencattini
In these notes we review and further explore the Lie enveloping algebra of a post-Lie algebra. From a Hopf algebra point of view, one of the central results, which will be recalled…
PRIMASS visits Hilda and Cybele groups
M. N. De Prá, N. Pinilla-Alonso, J. M. Carvano +5
The Cybele and Hilda dynamical groups delimit the outer edge of the asteroid belt. Their compositional distribution is a key element to constrain evolutionary models of the Solar S…
On the proper treatment of improper distributions
Bo H. Lindqvist, Gunnar Taraldsen
The axiomatic foundation of probability theory presented by Kolmogorov has been the basis of modern theory for probability and statistics. In certain applications it is, however, n…
Conditional fiducial models
Gunnar Taraldsen, Bo H. Lindqvist
The fiducial is not unique in general, but we prove that in a restricted class of models it is uniquely determined by the sampling distribution of the data. It depends in particula…

Henning G. Hugdal, Asle Sudbø
We study the superconducting order in a two-dimensional square lattice Hubbard model with weak repulsive interactions, subject to a Zeeman field and weak Rashba spin-orbit interact…
