The paper highlights the importance of using evolution strategy (ES) in investigating ultrashort pulse peak voltages in multiconductor structures of printed circuit boards (PCB). Trapezoidal ultrashort pulse propagation along the conductors of a real PCB multiconductor bus was simulated and, with ES, the whole ultrashort pulse duration was optimized using the criterion of peak voltage maximization in the PCB bus in order to identify the worst-case effects. The ES optimization was launched 10 times with different initial solutions (IS) – 3 ns, 300 ps, 30 ps. It is shown that changing the IS does not influence the optimization results. The voltage maximum exceeding the signal amplitude at the input by 20% and the crosstalk maximum exceeding that of the steady state level in the active conductor by 14% are detected and localized.

Vision is one of the well-researched sensing abilities of robots. However, applying vision-based algorithms can be challenging when used in different environmental conditions. One such challenge in vision-based localization is dynamic lighting conditions. In this paper, we present a new Gazebo plugin that enables realistic illumination changes depending on a current Sun's position. A plugin's ...

Introduction. The existing speech production schemes do not fully reflect the interaction of speech perception systems and one’s own internal speech. The study is aimed at comparing the connection between internal pronunciation and phonemic perception using psychophysi-ological methods. Methods. Twenty-five people took part in the EEG study. The subjects were offered auditory stimuli, and then ...

Based on the analysis of a large dataset for optimal undirected double-loop networks, we studied the problem of finding families of optimal double-loop graphs with the minimal possible diameter. Optimal double-loop networks are of practical interest as graph models for reliable, low-delay communication in computer systems and networks-on-chip, due to their advantageous networking properties. A ...

Theoretically, the helical edge states of two-dimensional topological insulators are protected from coherent
backscattering due to nonmagnetic disorder provided electron interactions are not too strong. Experimentally,
the edges typically do not demonstrate systematic and robust quantization, but at the same time little is known

In this paper, we suggest an extension of the Rosenzweig-Porter (RP) model, the LN-RP model, in which the off-diagonal matrix elements have a wide, log-normal distribution. We argue that this model is more suitable to describe a generic many-body localization problem. In contrast to RP model, in LN-RP model, a fragile weakly ergodic phase appears ...
