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: 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: 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…

Investigators: Miroslav Hain, Jozef Klembara A modern 3D imaging method was developed – X-ray microtomography. We optimized the physical parameters of microtomographic measurements and subsequent digital data processing methods, which ensured the minimization and elimination of artifacts, noise reduction, increased image contrast, and effective image data segmentation. The development and use of this modern non-destructive…

Investigator: Jiří PŘIBIL In the field of mapping the physiological and mental effects of scanning in MRI tomograph on the examined person, our research in 2024 was focused on refining the method of estimating blood pressure values directly from the PPG signal, without the use of an external blood pressure monitor. Several series of measurement…

Investigators: Hana Krakovská Stability is one of the most important concepts in dynamical systems. Local stability is a classical and well-studied concept, while defining and determining the “global” stability (robustness) of a nonlinear system is quite challenging. Over the past few decades, many different approaches have been developed to address this problem, primarily motivated by…

Extreme events such as unusual weather patterns, financial market crashes or epileptic seizures are the subject of intensive research to understand their mechanisms and to develop early warning methods. A new method, published in the prestigious scientific journal Science Advances [1], is helping to clarify which of several potential causes actually causes the extremes. The…
