A non-autonomous stochastic discrete time system with uniform disturbances
Ioannis K. Dassios, Krzysztof J. Szajowski
The main objective of this article is to present Bayesian optimal control over a class of non-autonomous linear stochastic discrete time systems with disturbances belonging to a fa…
Stability of topological properties of bismuth (111) bilayer
M. Bieniek, T. Wozniak, P. Potasz
We investigate electronic and transport properties of bismuth (111) bilayer in the context of stability of its topological properties against different perturbations. The effects o…
Asymptotic distributions of Wishart type products of random matrices
Romuald Lenczewski, Rafał Sałapata
We study asymptotic distributions of large dimensional random matrices of the form , where is a product of rectangular random matrices, using free probability and c…
Dirichlet heat kernel for the Laplacian in a ball
Jacek Malecki, Grzegorz Serafin
We provide sharp two-sided estimates on the Dirichlet heat kernel for the Laplacian in a ball. The result accurately describes the exponential behaviour of the kernel…
Do we really need to catch them all? A new User-guided Social Media Crawling method
Fredrik Erlandsson, Piotr Bródka, Martin Boldt +1
With the growing use of popular social media services like Facebook and Twitter it is challenging to collect all content from the networks without access to the core infrastructure…
Function spaces and extension results for nonlocal Dirichlet problems
Moritz Kassmann, Bartlomiej Dyda
We study function spaces and extension results in relation with Dirichlet problems involving integrodifferential operators. For such problems, data are prescribed on the complement…
Extremes of Multi-type Branching Random Walks: Heaviest Tail Wins
Ayan Bhattacharya, Krishanu Maulik, Zbigniew Palmowski +1
We consider a branching random walk on a multi()-type, supercritical Galton-Watson tree which satisfies Kesten-Stigum condition. We assume that the displacements associated with…
Assortative Mating: Encounter-Network Topology and the Evolution of Attractiveness
S. Dipple, T. Jia, T. Caraco +2
We model a social-encounter network where linked nodes match for reproduction in a manner depending probabilistically on each node`s attractiveness. The developed model reveals tha…
On Location Hiding in Distributed Systems
Karol Gotfryd, Marek Klonowski, Dominik Pająk
We consider the following problem - a group of mobile agents perform some task on a terrain modeled as a graph. In a given moment of time an adversary gets an access to the graph a…
Potential kernels, probabilities of hitting a ball, harmonic functions and the boundary Harnack inequality for unimodal Lévy processes
Tomasz Grzywny, Mateusz Kwaśnicki
In the first part of this article, we prove two-sided estimates of hitting probabilities of balls, the potential kernel and the Green function for a ball for general isotropic unim…
How to measure the topological quality of protein grammars?
Witold Dyrka, François Coste, Olgierd Unold +2
Context-free and context-sensitive formal grammars are often regarded as more appropriate to model proteins than regular level models such as finite state automata and Hidden Marko…
The Effects of Communication Burstiness on Consensus Formation and Tipping Points in Social Dynamics
Casey Doyle, Boleslaw Szymanski, Gyorgy Korniss
Current models for opinion dynamics typically utilize a Poisson process for speaker selection, making the waiting time between events exponentially distributed. Human interaction t…
Environmental Bisimulations for Delimited-Control Operators with Dynamic Prompt Generation
Andrés Aristizábal, Dariusz Biernacki, Sergueï Lenglet +1
We present sound and complete environmental bisimilarities for a variant of Dybvig et al.'s calculus of multi-prompted delimited-control operators with dynamic prompt generation. T…
Time-dependent current into and through multilevel parallel quantum dots in a photon cavity
Vidar Gudmundsson, Nzar Rauf Abdullah, Anna Sitek +3
We analyze theoretically the charging current into, and the transport current through, a nanoscale two-dimensional electron system with two parallel quantum dots embedded in a shor…
Tricriticality in the -neighbor Ising model on a partially duplex clique
Anna Chmiel, Julian Sienkiewicz, Katarzyna Sznajd-Weron
We analyze a modified kinetic Ising model, so called -neighbor Ising model, with Metropolis dynamics, [Phys. Rev. E 92, 052105], on a duplex clique and a partially duplex clique…
Learning Deep Architectures for Interaction Prediction in Structure-based Virtual Screening
Adam Gonczarek, Jakub M. Tomczak, Szymon Zaręba +3
We introduce a deep learning architecture for structure-based virtual screening that generates fixed-sized fingerprints of proteins and small molecules by applying learnable atom c…
Efficient determination of the Markovian time-evolution towards a steady-state of a complex open quantum system
Thorsteinn H. Jonsson, Andrei Manolescu, Hsi-Sheng Goan +4
Master equations are commonly used to describe time evolution of open systems. We introduce a general method for calculating a Markovian solution of the Nakajima-Zwanzig generalize…
A picture is worth a thousand words: an empirical study on the influence of content visibility on diffusion processes within a virtual world
Jarosław Jankowski, Piotr Bródka, Juho Hamari
Studying information diffusion and the spread of goods in the real world and in many digital services can be extremely difficult since information about the information flows is ch…
Balancing Speed and Coverage by Sequential Seeding in Complex Networks
Jarosław Jankowski, Piotr Bródka, Przemysław Kazienko +3
Information spreading in complex networks is often modeled as diffusing information with certain probability from nodes that possess it to their neighbors that do not. Information…
Conformity, anticonformity and polarization of opinions: insights from a mathematical model of opinion dynamics
Tyll Krueger, Janusz Szwabiński, Tomasz Weron
Understanding and quantifying polarization in social systems is important because of many reasons. It could for instance help to avoid segregation and conflicts in the society or t…
