Investigators: M. Trutz, A. Kulišov, and M. Hain Over more than three decades, the Institute of Measurement of the Slovak Academy of Sciences has gradually developed and supplied automated systems for measuring the inclination of reactor vessels to all currently operational units at the Mochovce and Jaslovské Bohunice nuclear power plants. These measurement systems use…

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…

Investigators: Ladislav Valkovič, Iveta Pajanová Cardiac energy metabolism is still rather dependent on the experience of the operator, both at the acquisition and analysis stages. Mainly because any shift in the acquisition matrix or wrong voxel selection increase inaccuracy, which is one of the reasons why this promising technique is not yet used in clinical…

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…

Investigators: Michal Teplan, Hoang Vu Viet This work presents the use of biological autoluminescence (BAL) to monitor the electroporation of yeast cells in real time. We have developed a device that can detect changes in the autoluminescence of the yeast Saccharomyces cerevisiae during the application of pulsed electric fields (PEF). This approach offers a non-invasive…

The research focused on the development of a new type of aluminosilicate glass and glass-ceramics. The effect of the method of preparation of gelenite glasses (2CaO-Al2O3-SiO2) doped with Bi was investigated. The glasses in question were prepared by a combination of flame synthesis and solid-phase reaction and a rapid cooling method. The obtained knowledge can…

Investigators: M. Škrátek, J. Maňka Chronic stress is a risk factor for several chronic non-communicable diseases. The chronic release of glucocorticoids and catecholamines during stress is thought to activate mechanisms that induce oxidative stress and inflammation. The transcription factor NRF2 regulates the expression of genes encoding proteins involved in iron metabolism, as well as antioxidant…
