Investigators: Viktor WITKOVSKÝ, Laura HAJZOKOVÁ , IMS SAS + foreign partners In 2023, our collaboration with researchers from the University of Montenegro contributed to advances in probabilistic modelling and numerical methods and algorithms for the computation of complex probability distributions, which are often encountered in the analysis of uncertainties in measurement results in various application…
Investigators: Viktor WITKOVSKÝ, Gejza WIMMER, Jr., Laura HAJZOKOVÁ , IMS SAS + foreign partners In 2023, we made further progress in pain research in collaboration with our partners. With EuroPainClinics, we investigated the impact of percutaneous endoscopic lumbar discectomy on the quality of life of 470 patients with sciatic syndrome. We were able to show…
Investigators: Anna Krakovská, Martina Chvosteková, Jozef Jakubík Identifying causal relationships in measured time series is a research topic that we have been working on intensively for several years. This year we have focused on discovering causality in cases where traditional tools such as the Granger test, successful for example in autoregressive processes, are not applicable…
Investigators: Michal Teplan, Hoang Vu Viet In the area of the effect of pulsed electric fields (PEF) on sub-cellular structures, we investigated the manipulation of microtubules (MT) using PEF. In cooperation with ÚFE AVČR, we created new statistical measures for measuring MT movement for images from the “single molecule TIRF” microscope, which we called “microtubule…
Investigators: Viktor WITKOVSKÝ, Gejza WIMMER, Jr., Laura HAJZOKOVÁ Institute of SAS Measurement, v.v.i. + foreign partners In collaboration with our partners, we investigated the problem of understanding endogenous chronic pain with the aim of finding and elucidating mechanisms to alleviate suffering. Therefore, we focused on studying the course of brain activity in patients with migraine…
Investigators: Roman Rosipal, Zuzana Rošťáková The detection and changes of oscillatory rhythms in the EEG signal are important for understanding the processes taking place in the human brain during experiments aimed at modulating brain activity, as well as for the proper functioning of the brain-computer interface. In [1], we created a set of simulated EEG…

Investigators: Michal Teplan, Martin Bereta Oxidative metabolism is a process that occurs in organisms during their physiological and pathophysiological conditions. Monitoring biological oxidation processes caused by chemical or physical stimuli is currently extremely important due to the environmental burden of various physicochemical factors. Existing techniques usually require the addition of chemical markers or illumination, which,…
Investigators: Martina Chvosteková, Anna Krakovská, Jozef Jakubík Identifying the causal link between processes in a complex system is one of the fundamental challenges in the natural and social sciences. The first principle of Granger causality as the basic quantitative analysis of causality is the chronological order of cause and effect. The effect of the…
Investigators: Anna Krakovská, Jozef Jakubík Methods of causal analysis have been applied in diverse scientific fields from economics, through climate sciences to research trying to understand connections in the human brain. We already know that time series from dynamical systems require different approaches than, for example, causal analysis of interconnected autoregressive processes. In [1]…
