Kendall transformation: a robust representation of continuous data for information theory
Miron Bartosz Kursa
Kendall transformation is a conversion of an ordered feature into a vector of pairwise order relations between individual values. This way, it preserves ranking of observations and…
Memory-efficient Lattice Boltzmann Method for low Reynolds number flows
Maciej Matyka, Michał Dzikowski
The Lattice Boltzmann Method algorithm is simplified by assuming constant numerical viscosity (the relaxation time is fixed at ). This leads to the removal of the distribution…
Monitoring Achilles tendon healing progress in ultrasound imaging with convolutional neural networks
Piotr Woznicki, Przemyslaw Przybyszewski, Norbert Kapinski +5
Achilles tendon rupture is a debilitating injury, which is typically treated with surgical repair and long-term rehabilitation. The recovery, however, is protracted and often incom…
Suppressed solitonic cascade in spin-imbalanced superfluid Fermi gas
Gabriel Wlazłowski, Kazuyuki Sekizawa, Maciej Marchwiany +1
Cold atoms experiments offer invaluable information on superfluid dynamics, including decay cascades of topological defects. While the cascade properties are well established for B…
Assessment of approaches for dispersive forces employing graphone as a case study
Magdalena Birowska, Maciej Marchwiany, Claudia Draxl +1
We have studied two interchange layer systems, (i) free standing partly hydrogenated graphene (graphone), and (ii) graphone on the Nickel (111) surface, to assess various density f…
The Mass-Concentration-Redshift Relation of Cold and Warm Dark Matter Halos
Aaron D. Ludlow, Sownak Bose, Raúl E. Angulo +5
We use a suite of cosmological simulations to study the mass-concentration-redshift relation, , of dark matter halos. Our simulations include standard -cold dark m…
Constraints on the identity of the dark matter from strong gravitational lenses
Ran Li, Carlos S. Frenk, Shaun Cole +3
The cold dark matter (CDM) cosmological model unambigously predicts that a large number of haloes should survive as subhaloes when they are accreted into a larger halo. The CDM mod…
Percolation thresholds for discrete-continuous models with non-uniform probabilities of bond formation
Bartłomiej Szczygieł, Marek Dudyński, Kamil Kwiatkowski +3
We consider a family of percolation models in which geometry and connectivity are defined by two independent random processes. Such models merge characteristics of discrete and con…
Modified Gravity N-body Code Comparison Project
Hans A. Winther, Fabian Schmidt, Alexandre Barreira +12
Self-consistent -body simulations of modified gravity models are a key ingredient to obtain rigorous constraints on deviations from General Relativity using large-scale st…
Planes of satellite galaxies: when exceptions are the rule
Marius Cautun, Sownak Bose, Carlos S. Frenk +5
The detection of planar structures within the satellite systems of both the Milky Way (MW) and Andromeda (M31) has been reported as being in stark contradiction to the predictions…
On the structure of Lipschitz-free spaces
Marek Cuth, Michal Doucha, Przemyslaw Wojtaszczyk
In this note we study the structure of Lipschitz-free Banach spaces. We show that every Lipschitz-free Banach space over an infinite metric space contains a complemented copy of $\…
The Copernicus Complexio: a high-resolution view of the small-scale Universe
Wojciech A. Hellwing, Carlos S. Frenk, Marius Cautun +5
We introduce Copernicus Complexio (COCO), a high-resolution cosmological N-body simulation of structure formation in the model. COCO follows an approximately spheric…
The Milky Way system in LCDM cosmological simulations
Qi Guo, Andrew Cooper, Carlos Frenk +2
We apply a semi-analytic galaxy formation model to two high resolution cosmological N-body simulations to investigate analogues of the Milky Way system. We select these according t…
Towards Autotuning of OpenMP Applications on Multicore Architectures
Jakub Katarzyński, Maciej Cytowski
In this paper we describe an autotuning tool for optimization of OpenMP applications on highly multicore and multithreaded architectures. Our work was motivated by in-depth perform…
Halo model and halo properties in Galileon gravity cosmologies
Alexandre Barreira, Baojiu Li, Wojciech A. Hellwing +3
We investigate the performance of semi-analytical modelling of large-scale structure in Galileon gravity cosmologies using results from N-body simulations. We focus on the Cubic an…
A clear and measurable signature of modified gravity in the galaxy velocity field
Wojciech A. Hellwing, Alexandre Barreira, Carlos S. Frenk +2
The velocity field of dark matter and galaxies reflects the continued action of gravity throughout cosmic history. We show that the low-order moments of the pairwise velocity distr…
General aspects of the vapor growth of semiconductor crystals - a study based on DFT simulations of the NH3/NH2 covered GaN(0001) surface in hydrogen ambient
Pawel Kempisty, Pawel Strak, Konrad Sakowski +1
Vapor growth of semiconductors is analyzed using recently obtained dependence of the adsorption energy on the electron charge transfer between the surface adsorbed species and the…
The hemagglutinin mutation E391K of pandemic 2009 influenza revisited
Jan P. Radomski, Piotr Płoński, Włodzimierz Zagórski-Ostoja
Phylogenetic analyses based on small to moderately sized sets of sequential data lead to overestimating mutation rates in influenza hemagglutinin (HA) by at least an order of magni…
Tagging Scientific Publications using Wikipedia and Natural Language Processing Tools. Comparison on the ArXiv Dataset
Michał Łopuszyński, Łukasz Bolikowski
In this work, we compare two simple methods of tagging scientific publications with labels reflecting their content. As a first source of labels Wikipedia is employed, second label…
Simulating the quartic Galileon gravity model on adaptively refined meshes
Baojiu Li, Alexandre Barreira, Carlton M. Baugh +4
We develop a numerical algorithm to solve the high-order nonlinear derivative-coupling equation associated with the quartic Galileon model, and implement it in a modified version o…
