Cell phones are no longer merely used to make phone calls or to send short or multimedia messages. They more and more become information systems clients. Recent developments in the areas of mobile computing, wireless networks and information systems provide access to data at almost every place and anytime by using this kind of lightweight mobile device. But even though mobile clients support th...

The new generations of cars have a number ECUs (Electronic Control Units) which are connected to central gateway and need pass cybersecurity integration tests fulfil the homologation requirements cars. Cars usually server (few additional domain servers) with Linux large real time control actuators (ESP, EPS, ABS, etc. – they multicore embedded controllers) by automotive specific bus (CAN-FD) co...

The Logical Key Hierarchy (LKH) provides a scalable and efficient way to distribute session keys to authorized group members in secure group (multicast) communication. However, because multicast is a best-effort service, it requires additional mechanism to ensure that every member receives the rekey information. To solve this problem, several FEC-based schemes have been proposed. Although these...

Blockchain technology radically transforms resource management mechanisms at any level and scope of activity, making them highly productive, perfect, efficient. The purpose this paper is to consider the prospects for application blockchain in healthcare supply chain management. essence as a systematized database stored on more than one server corresponds tasks modern healthcare. An additional a...

A 2D finite-differences time-domain full-wave code is used to simulate the measurements of plasma filaments with fixed frequency O-mode reflectometry. The plasma is modeled by a linear slab plasma plus a Gaussian perturbation propagating in a direction that can vary from poloidal to radial. The plasma background density gradient is chosen in agreement with the steep edge transport barrier of H-...

We conducted a retrospective study of 36 cases of ameloblastoma from the files of Mittaphap Hospital in Vientiane Capital, Laos. Clinical findings showed an average patient age of 31.0 ± 3.8 years, with a slight male preponderance. Radiographically, all of the lesions showed multicystic radiotranslucency. Twenty-four patients underwent tumor resection and 12 underwent tumor enucleation. Of thos...

A spatially and temporally realistic simulation of Escherichia coli chemotaxis was used to investigate the swimming patterns of wild-type and mutant bacteria within a rectangular arena in response to chemoattractant gradients. Swimming dynamics were analysed during long time series with phase-space trajectories, power spectra and estimations of fractal dimensions (FDs). Cell movement displayed ...

This article considers those monoids S satisfying one or both of the finitary properties (R) and (r), focussing for the most part on inverse monoids. These properties arise from questions of axiomatisability of classes of S-acts, and appear to be of interest in their own right. If S weakly right noetherian (WRN), that is, S has the ascending chain condition on right ideals, then certainly (r) h...
