Elemental and tight monogamy relations in nonsignaling theories
PublikacjaPhysical principles constrain the way nonlocal correlations can be distributed among distant parties. These constraints are usually expressed by monogamy relations that bound the amount of Bell inequality violation observed among a set of parties by the violation observed by a different set of parties. We prove here that much stronger monogamy relations are possible for nonsignaling correlations by showing how nonlocal correlations...

Interventions reducing car usage: Systematic review and meta-analysis
PublikacjaThis systematic literature review aimed to investigate the extent to which transport-related interventions induced a reduction in car use. Both qualitative synthesis and meta-analysis were employed. The synthesis included 31 original studies, while the meta-analysis included 21. Of the qualitatively synthesised studies, 74 % demonstrated that interventions were effective in reducing car use. The pooled estimates of the effects...

Molecular dynamics studies of polyurethane nanocomposite hydrogels
PublikacjaPolyurethane PEO-based hydrogels have a broad range of biomedical applicability. They are attractive for drug-controlled delivery systems, surgical implants and wound healing dressings. In this study, a PEO based polyurethane hydrogels containing Cloisite R 30B, an organically modified clay mineral, was synthesized. Structure of nanocomposite hydrogels was determined using XRD technique. Its molecular dynamics was studied by means...

Distance learning trends: introducing new solutions to data analysis courses
PublikacjaNowadays data analysis of any kind becomes a piece of art. The same happens with the teaching processes of statistics, econometrics and other related courses. This is not only because we are facing (and are forced to) teach online or in a hybrid mode. Students expect to see not only the theoretical part of the study and solve some practical examples together with the instructor. They are waiting to see a variety of tools, tutorials,...

Anharmonic Infrared Spectroscopy through the Fourier Transform of Time Correlation Function Formalism in ONETEP
PublikacjaDensity functional theory molecular dynamics (DFT-MD) provides an efficient framework for accurately computing several types of spectra. The major benefit of DFTMD approaches lies in the ability to naturally take into account the effects of temperature and anharmonicity, without having to introduce any ad hoc or a posteriori corrections. Consequently, computational spectroscopy based on DFT-MD approaches plays a pivotal role in...

Generalized Chebyshev Bandpass Filters With Frequency-Dependent Couplings Based on Stubs
PublikacjaThis paper presents an accurate synthesis method for inline and cross-coupled generalized Chebyshev bandpass filters with frequency-dependent couplings implemented via open and short stubs. The technique involves the synthesis of a lumped-element prototy pe in the form of a coupling matrix with a frequency-dependent term and the conversion of this prototype to a distributed-element mode l composed of sections of TEM lines. This...

Firing map of an almost periodic input function
PublikacjaIn mathematical biology and the theory of electric networks the firing map of an integrate-and-fire system is a notion of importance. In order to prove useful properties of this map authors of previous papers assumed that the stimulus function f of the system ẋ = f(t,x) is continuous and usually periodic in the time variable. In this work we show that the required properties of the firing map for the simplified model ẋ = f(t) still...

The nature of emitting states in electroluminescence of polymeric films do-ped with anthracene andanthracene-based supramolecules
PublikacjaZaobserwowano nową odmianę bi-molekularnych stanów wzbudzenia elektronowego w polimerowych jednowarstwowych diodach EL z molekułami antracenu wbudowanymi bezpośrednio w matrycę poliwęglanową, jak i pośrednio przez ich włączenie jako grup chromoforowych w dużych makromolekułach rotaxanowych. Stwierdzono, że obok typowej emisji ekscymerowej pojawia się długofalowe pasmo elektromerowe. Pasmo to związane jest z emisją kolumbowsko związanych...

POWŁOKOWA KOMPOZYTOWA KŁADKA DLA PIESZYCH O KONSTRUKCJI PRZEKŁADKOWEJ
PublikacjaPrzedstawiono koncepcję kompozytowej kładki pieszo-rowerowej w formie kon-strukcji powłokowej przekładkowej w kształcie litery U. Przęsło kładki jest swobodnie podparte, o rozpiętości 16,00 m, a szerokość użytkowa wynosi 2,60 m. Okładki prze-kładkowego dźwigara głównego są laminatami uniepalnionymi winyloestrowo – szkla-nymi. Tkaniny, wytworzone ze szkła E, są ortogonalne, zrównoważone, zszywane. Rdzeń przekładkowego dźwigara głównego...

Site-selective magnetic order of neptunium inNp2Ni17
PublikacjaWe present the results obtained by superconducting quantum interference device (SQUID) magnetometry, specific heat, and Mossbauer spectroscopy measurements carried out on Np2Ni17 polycrystalline samples. We show that long-range magnetic order, with a moment mu((2b)) similar to 2.25 mu(B), occurs below T-N = 17.5 K on the Np (2b) sites. A nontrivial situation is observed in that the other Np sites (2d) do not take part to the order...
