Abstract: Funding: This work was supported by the Slovenian Research Agency; Program No. P5-0018 – Decision Support Systems in Digital Business and the HSE University Basic Research Program. Conflicts of interest: All authors declare that they have no conflicts of interest. Ethics statement: All procedures performed in this study involving human participants were in accordance with the ethical standards of the University of Maribor, Faculty of Organizational Sciences research committee (decision no. 514/5/2021/1/902-DJ) and with the 1964 Helsinki Declaration and its later amendments or comparable ethical standards. Background and purpose: Technology acceptance has been researched for decades. While some technologies are widely accepted, others are perceived as a threat, such as microchip implants. In this study, a two-step structural equation modeling approach was used to evaluate a new research model on microchip implant acceptance. Methodology: A structural equation modeling model was developed to identify what influences the perceived acceptance of microchip implants. To determine differences in attitudes toward microchip implants, the study was conducted in five Eastern European countries. Results: The results show that the influence of the factors does not differ significantly across the countries studied. Age, trust, and perceived usefulness affected the overall intention to use microchip implants, while ease of use was significant in only one country. Differences were found in perceptions of the right to privacy and conspiracy theories. The usefulness of microchip implants in pandemic was significant in all countries. Conclusion: Small differences in attitudes towards microchip implants suggest that a general model of microchip implant acceptance could be constructed based on the data collected. In addition to these findings, our study noted the lack of legislation for microchip implants in the region and a lack of knowledge about this technology.

Abstract: This paper presents a platform developed for automated magnetic flux density measurement. The platform was designed to be used to measure the magnetic flux density of the transmitter/receiver coil of an inductive wireless power transfer system. The magnetic flux density of a transmitter was measured using a small, 3-axis search coil. The search coil was positioned in the 3D space above the transmitter coil using a 3D positioning mechanism and used to measure the magnetic flux density at a specific point. The data was then sent to a computer application to visualize the magnetic flux density. The measured magnetic field could be used in combination with electromagnetic field solvers to design and optimize transmitter coils for inductive wireless power transfer systems.
Keywords: magnetic field, magnetic flux density, IPT, transmitter coil design, EM solver

Abstract: Coarse-grained molecular dynamics simulations are highly valuable for studying protein-protein interactions. Unfortunately, commonly used force fields often overestimate these interactions. Here, we investigate the performance of the Martini 3 force field in predicting the self-interaction behavior of lysozyme and subtilisin using Metadynamics. The original Martini 3, despite improvements over its predecessor, overestimates interaction strength. Through reparameterization of bead interactions, we achieve good agreement with experimental data of the second virial coefficient and the diffusion coefficient. The new, refined force field enables more accurate CG-MD simulations, with potential applications in understanding and prediction of protein stability, aggregation tendencies, and solubility, with the possibility to aid in the development of protein-based drugs.
Keywords: coarse-grained molecular dynamics, Martini 3 force field, protein-protein interactions, B22, reparameterization, NMR, diffusion coefficient

Abstract: This master's thesis addresses the issue of surveillance and the right of access to protected zones. NFC technology was selected as a solution for identifying and monitoring sliding doors. The monitoring system is connected to the web server via an Internet connection, which enables easier data processing and more straightforward data access. In this master's thesis, a scaled sliding door model was used that was made using a 3D printer. The thesis also addresses the issue of powering the system using an uninterruptible power supply (UPS) system in the event of a power outage. The monitoring and control system is designated and implemented as a modular system consisting of a UPS, NFC, and the main module. The UPS module powers the system and ensures an uninterrupted power supply. The NFC module is used to communicate between the user of the NFC key and the system. The main module is intended for processing the data received from other modules and components in the security system, managing the sliding doors, and sending the processed data to the controller.
Keywords: access control system, near-field communication, ISO/IEC 14443 standard, radio frequency identification, sliding door

Abstract: The environmental species Pseudomonas aeruginosa thrives in a variety of habitats. Within the epidemic population structure of P. aeruginosa, occassionally highly successful clones that are equally capable to succeed in the environment and the human host arise. Framed by a highly conserved core genome, individual members of successful clones are characterized by a high variability in their accessory genome. The abundance of successful clones might be funded in specific features of the core genome or, although not mutually exclusive, in the variability of the accessory genome. In clone C, one of the most predominant clones, the plasmid pKLC102 and the PACGI-1 genomic island are two ubiquitous accessory genetic elements. The conserved transmissible locus of protein quality control (TLPQC) at the border of PACGI-1 is a unique horizontally transferred compository element, which codes predominantly for stress-related cargo gene products such as involved in protein homeostasis. As a hallmark, most TLPQC xenologues possess a core genome equivalent. With elevated temperature tolerance as a characteristic of clone C strains, the unique P. aeruginosa and clone C specific disaggregase ClpG is a major contributor to tolerance. As other successful clones, such as PA14, do not encode the TLPQC locus, ubiquitous denominators of success, if existing, need to be identified.
Keywords: disaggregase, FtsH, genomic island, protein homeostasis, pulsed field gel electrophoresis, whole genome sequencing
