Investigators: Anna Přibilová, Jana Švehlíková, Ján Zelinka, Milan Tyšler The study proposes parameters potentially suitable for optimal ventricular stimulation settings in cardiac resynchronization therapy. The parameters are determined from autocorrelation maps (ACM) calculated from surface potential maps of 17 patients, 14 of whom have left bundle branch block and three have right bundle branch block….

Investigators: Ladislav Valkovič, Pavol Szomolányi Quantifying the concentration of energy metabolites requires accurate measurement of the magnetic field (B1), especially at 7T where the excitation coils face large field inhomogeneities. Measuring the B1 field using standard signal sampling is relatively time-consuming. It takes about 40 minutes to cover the entire heart, which is too long…

Investigator: Radka Klepochová In this work, we focused on obtaining information about two key processes at the same time: the depletion and recovery of intramuscular phosphocreatine (PCr) using ³¹P MRS and the behavior of the creatine CH₂ signal in ¹H MRS, which exhibits similar dynamics. While previous studies required separate ¹H and ³¹P measurements with…

Investigators: Daniel Gogola, Rudolf Tanglmajer, Dušan Mašek For the Ionizing Radiation Department of the Slovak Metrology Institute, a device was developed to automate the measurement of neutron radiation source anisotropy and to measure the response of neutron detectors depending on the angle or angular distribution. Aplicator of the result: Ionizing Radiation Department, Slovak Institute of…

Investigators: Jiří PŘIBIL, Tomáš Dermek As part of the VEGA project, a new prototype of a multi-channel wearable PPG sensor with integrated contact thermo-chips and a pressure sensor based on force-sensitive resistors (FSR) was developed and tested in practice. The sensor is capable of measuring in the weak magnetic field environment of an NMR tomograph….

Investigators: Viktor Witkovský (ÚM SAV), Gejza Wimmer (MÚ SAV), Anna Charvátová Campbell (ČMI), Petr Klapetek (ČMI), Radek Šlesinger (ČMI) As part of the international bilateral SK-CZ project, we designed and implemented efficient computational methods for evaluating the mechanical properties of materials at the nanoscale using instrumented indentation (IIT) and atomic force microscopy (AFM). The OEFPIL…

Investigators: Nina Evetović, Arina Polyanskaya, Roman Rosipal, Zuzana Rošťáková Integrated brain-computer interface (BCI) and virtual reality (VR) technologies provide a flexible platform for a series of neurorehabilitation therapies based on motor imagery in patients after stroke. However, these approaches lack the social aspect and human interaction. As part of our research, we successfully designed an intelligent…

Investigators: Roman Rosipal, Zuzana Rošťáková  An electroencephalogram (EEG) recorded with eyes open is contaminated by artifacts related to eye blinks and eye movements, which should be removed before further analysis. For this purpose, we developed SPECTER, an algorithm that combines tensor decomposition of the EEG spectrum, removal of artifact components, and spectrum-to-signal transformation. In contrast…

Determining the amount of iron in tissue and blood samples from laboratory animals allows us to understand the relationships of its metabolism in the body. Common laboratory methods do not allow us to distinguish between different forms of iron, so SQUID magnetometry appears to be a suitable tool for monitoring these changes. Various iron-containing proteins…

Investigators: M. Majerová, A. Prnová, J. Valúchová, M. Michálková, B. Pecušová, M. Žitňan, D. Galusek Ceramic and glass-ceramic materials in the binary system Y2O3-Al2O3 (yttrium aluminum garnet Y3Al5O12 – YAG; yttrium aluminum perovskite, YAlO3-YAP, and yttrium aluminum melilite, Y2Al4O-YAM) are being intensively studied due to their excellent optical and mechanical properties. A special group is…
