An improved convergence bound for the polynomially accelerated two-level method of Brousek et al. [Electron. Trans. Numer. Anal., 44 (2015), pp. 401–442, Section 5] is proven. This method is a reinterpretation of the smoothed aggregation method with an aggressive coarsening and massive ...

NKG2D and its ligands, MICA and MICB, are known as the key regulators of NK cells. NK cells are the first reconstituted cells after the allogeneic hematopoietic stem cell transplantation (HSCT); therefore, it is crucial to understand their role in HSCT outcome. In the presente...

Natural killer cells possess key regulatory function in various malignant diseases, including acute myeloid leukemia. NK cell activity is driven by signals received through ligands binding activating or inhibitory receptors. Their activity towards elimination of transformed or virally infected cells&#...

This paper presents a short summary of a dissertation thesis. The thesis presents a novel approach named X-Bridge for image-to-sketch translation for automatic heterogeneous face recognition. X-Bridge is based on a conditional adversarial network with an additional reconstruction path and a ...

The growth of crystalline ZrO2 is studied by a combined approach of atom-by-atom growth simulations, high-power impulse magnetron sputtering and conventional pulsed magnetron sputtering. We focus on the energy of arriving atoms of various elements and investigate how does it affect the ...

In this paper, we deal with the second order difference equation with asymmetric nonlinearities on the integer lattice and we investigate the distribution of zeros for continuous extensions of positive semi-waves. The distance between two consecutive zeros of two different positive semi-wave...

The paper deals with development of a methodology for mechatronic system design using state-of-the-art model-based system engineering methods. A simple flexible robotic arm is considered as a benchmark problem for the evaluation of various techniques used in the phases of modelling, analysis...

Nanoindentation experiments in metal surfaces are characterized by the onset of plastic instabilities along with the development of permanent nanoimprints and dense defect networks. This investigation concerns massive molecular dynamics simulations of nanoindentation experiments in FCC, BCC and HCP me...

Time-averaged and time-resolved ion fluxes during reactive HiPIMS deposition of Ti–Al–N thin films are thoroughly investigated for the usage of Ti–Al composite targets. Ion mass spectroscopy analysis revealed, that increasing Al content in the target material or reducing the N2 flow-rate rat...

We investigated in detail the influence of 2 at.% tungsten in the Al-target on the process stability and phase formation during reactive DC magnetron sputtering as well as high power impulse magnetron sputtering (HiPIMS) of Al2O3-based coatings. The small addition of W to the ...

This work brings an overview of the nonlinear dynamics of four-segment tilting pad journal bearings (TPJB) in load-between-pads configuration supported on flexible pivots. We focus primarily on analysing the sub-synchronous motion of statically unloaded pads, also called pad fluttering. In this&#...

Current industrial trends bring new challenges in energy absorbing systems. Polymer materials as the traditional packaging materials seem to be promising due to their low weight, structure, and production price. Based on the review, the linear low-density polyethylene (LLDPE) material was id...

The Geodesist’s Handbook is published by the International Association of Geodesy (IAG) periodically after each IUGG/IAG General Assembly. The objective is to present the current IAG structure and its specifications, and to introduce the terms of reference and the officers of the A...

This paper studies the contribution of airborne gravity data to improvement of gravimetric geoid modelling across the mountainous area in Colorado, USA. First, airborne gravity data was processed, filtered, and downward-continued. Then, three gravity anomaly grids were prepared; the first grid&#x...

Theoretical models indicate that reactive HiPIMS can deliver higher deposition rates compared to the mid-frequency pulsed dc magnetron sputtering (Mf-PDCMS) due to a lower degree of target poisoning. To confirm these theoretical results, series of experiments were performed in laboratory depositi...

The vertical motion of the Earth’s surface is dominated by the hydrologic cycle on a seasonal scale. Accurate land deformation measurements can provide constructive insight into the regional geophysical process. Although the Global Positioning System (GPS) delivers relatively accurate measurements,&#x...

We consider a one-dimensional reaction–diffusion equation of Fisher–Kolmogoroff– Petrovsky–Piscounoff type. We investigate the effect of the interaction between the nonlinear diffusion coefficient and the reaction termon the existence and non-existence of travelling waves. Our diffusion coefficient is allowed&#...

Two-dimensional wave propagation in an aluminium strip is examined experimentally, analytically, and numerically in this paper. The high-frequency pulse is generated by a piezoelectric transducer, and the velocity component normal to the strip edge is measured by the non-contact vibrometer system...

Epidemiologic evaluation of pelvic ring injuries in children. Methods Retrospective analysis over a period of 13 years, excluding pathological fractures. AO/OTA type, epidemiological data, type of treatment, and complications were recorded. Data were assessed using Fisher’s exact test and Wilcoxo...

This paper studies the Eulerian-Lagrangian and Eulerian-Eulerian approaches for the simulation of interaction between free surface flow and particles. The dynamics of the fluid as well as the transport of the particles in the Eulerian description is solved using the lattice Boltzmann me...
