Graphene Oxide and Polymer Humidity Micro-Sensors Prepared by Carbon Beam Writing
Petr Malinský, Oleksander Romanenko, Vladimír Havránek +8
In this study, novel flexible micro-scale humidity sensors were directly fabricated in graphene oxide (GO) and polyimide (PI) using ion beam writing without any further modificatio…
Strain localization in planar shear of granular media: the role of porosity and boundary conditions
Stanislav Parez, Tereza Travnickova, Martin Svoboda +1
Shear strain localization into shear bands is associated with velocity weakening instabilities and earthquakes. Here, we simulate steady-state plane-shear flow of numerical granula…
Thermodynamic perturbation theory and equation of state developments
I. Nezbeda
An alternative way of utilizing the thermodynamic perturbation theory of Wertheim for the development of equations of state for associating fluid models is presented and detailed f…
Pointwise inequalities for Sobolev functions on outward cuspidal domains
Sylvester Eriksson-Bique, Pekka Koskela, Jan Maly +1
We show that the first order Sobolev spaces on cuspidal symmetric domains can be characterized via pointwise inequalities. In particular, they coincide with the Hajlasz-Sobolev spa…
Evolution of Relative Magnetic Helicity: New Boundary Conditions for the Vector Potential
Shangbin Yang, Joerg Buechner, Jan Skala +1
We recently proposed a method to calculate the relative magnetic helicity in a finite volume for a given magnetic field which however required the flux to be balanced separately on…
Molecular Simulation of Caloric Properties of Fluids Modelled by Force Fields with Intramolecular Contributions: Application to Heat Capacities
William R. Smith, Jan Jirsák, Ivo Nezbeda +1
The calculation of caloric properties such as heat capacity, Joule-Thomson coefficients and the speed of sound by classical force-field-based molecular simulation methodology has r…
Recent Progress in Molecular Simulation of Aqueous Electrolytes: Force Fields, Chemical Potentials and Solubility
Ivo Nezbeda, Filip Moučka, William R. Smith
Although aqueous electrolytes are among the most important solutions, the molecular simulation of their intertwined properties of chemical potentials, solubility and activity coeff…
Numerical RHD simulations of flaring chromosphere with Flarix
P. Heinzel, J. Kasparova, M. Varady +2
Flarix is a radiation-hydrodynamical (RHD) code for modeling of the response of the chromosphere to a beam bombardment during solar flares. It solves the set of hydrodynamic conser…
Hybrid simulations of chromospheric HXR flare sources
Z. Moravec, M. Varady, J. Kasparova +1
Recent measurements of vertical extents and positions of the chromospheric hard X-ray (HXR) flare sources based on Ramaty High-Energy Spectroscopic Imager (RHESSI) observations sho…
Quasiopen and p-path open sets, and characterizations of quasicontinuity
Anders Björn, Jana Björn, Jan Malý
In this paper we give various characterizations of quasiopen sets and quasicontinuous functions on metric spaces. For complete metric spaces equipped with a doubling measure suppor…
Direct sums and products in topological groups and vector spaces
Dikran Dikranjan, Dmitri Shakhmatov, Jan Spěvák
We call a subset of an abelian topological group : (i) provided that for every open neighbourhood of one can find a finite set $F\su…
Application of molecular simulations: Insight into liquid bridging and jetting phenomena
I. Nezbeda, J. Jirsák, F. Moučka +1
Molecular dynamics simulations have been performed on pure liquid water, aqueous solutions of sodium chloride, and polymer solutions exposed to a strong external electric field wit…
Virial expansions and augmented van der Waals approach: Application to Lennard-Jones-like Yukawa fluid
A. Trokhymchuk, R. Melnyk, I. Nezbeda
We argue that recently proposed [Melnyk et al., Fluid Phase Equilibr., 2009, Vol. 279, 1] a criterion to split the pair interaction energy into two parts, one of which is forced to…
The 3D MHD code GOEMHD3 for large-Reynolds-number astrophysical plasmas
J. Skála, F. Baruffa, J. Büchner +1
The numerical simulation of turbulence and flows in almost ideal, large-Reynolds-number astrophysical plasmas motivates the implementation of almost conservative MHD computer codes…
Modifications of thick-target model: re-acceleration of electron beams by static and stochastic electric fields
M. Varady, M. Karlický, Z. Moravec +1
We study two modifications of the collisional thick-target model (CTTM) based on the global and local re-acceleration of non-thermal electrons by static and stochastic electric fie…
Physical interpretation of Kundt spacetimes using geodesic deviation
Jiri Podolsky, Robert Svarc
We investigate the fully general class of non-expanding, non-twisting and shear-free D-dimensional geometries using the invariant form of geodesic deviation equation which describe…
A low rank property and nonexistence of higher dimensional horizontal Sobolev sets
Valentino Magnani, Jan Malý, Samuele Mongodi
We establish a "low rank property" for Sobolev mappings that pointwise solve a first order nonlinear system of PDEs, whose smooth solutions have the so-called "contact property". A…
Percolation line, response functions, and Voronoi polyhedra analysis in supercritical water
J. Skvor, I. Nezbeda
The problem of a physical relevance (meaning) of percolation in supercritical fluids is addressed considering a primitive model of water. Two different criteria, physical and confi…
Spontaneous current-layer fragmentation and cascading reconnection in solar flares: I. Model and analysis
Miroslav Bárta, Jörg Büchner, Marian Karlický +1
Magnetic reconnection is commonly considered as a mechanism of solar (eruptive) flares. A deeper study of this scenario reveals, however, a number of open issues. Among them is the…
An elementary way to introduce a Perron-like integral
Hana Bendová, Jan Malý
We give an alternative definition of integral at the generality of the Perron integral and propose an exposition of the foundations of integral theory starting from this new defini…
