Solution of spatial and verbal tasks was studied in 43 subjects using the advanced version of the method of intracortical interaction mapping (IIM) and analysis of EEG spectra in short (250 ms) intervals. Comparison between the IIM and coherence methods during solving simple motor tasks revealed some advantages of the IIM for studying of labile cortical connections. Several stages were separated i

The stages of the mental rotation of complex three-dimensional figures were investigated in nine healthy subjects using the intracortical interaction mapping technique. It was established that mental rotation is accomplished with the participation of both parietal regions; the prerotation setup is associated with the involvement of the frontal, central, and right temporal divisions of the brain; d

Effect of sustained mental work on the first stage of mental rotation was studied by the method of intracortical interaction. It was revealed that during sustained mental work the zone of the high level of connections in the alpha-band was considerably reduced due to an increase of specificity, rationality of thinking. In the beta-band the zone of the high connection level moved from the central a

The stages of mental rotation of complicated three-dimensional figures were studied using the intracortical interaction mapping. The role of the parietal areas in the mental rotation was shown. The frontal, central and the right temporal areas are involved in the prerotation setup. Both frontal areas and the left temporo-parieto-occipital areas participate in decision making and verbal response. I

Orthostatic hypertension, which appears to be mediated through excess neurohumoral activation while standing, is a common blood pressure trait among patients with and without arterial hypertension. However, lack of consensus regarding the definition of orthostatic hypertension makes it difficult to assess the true prevalence of this condition. Orthostatic hypertension appears to predict the risk f

Although diagnostic criteria have been developed characterizing postural orthostatic tachycardia syndrome (POTS), no single set of criteria is universally accepted. Furthermore, there are gaps in the present criteria to identify individuals who have this condition. The reproducibility of the physiological findings, the relationship of symptoms to physiological findings, the presence of symptoms al

The management of diabetic foot ulcers (DFU) remains a challenge, and there is continuing uncertainty concerning optimal approaches to wound healing. The International Working Group of the Diabetic Foot (IWGDF) working group on wound healing has previously published systematic reviews of the evidence in 2008, 2012 and 2016 to inform protocols for routine care and to highlight areas which should be

The rheology of dense suspensions in the viscous regime can be characterized by the viscous number J and granular flows by the inertia number I, both relating the shear rate γ - to the confining pressure P. Furthermore, several works have shown that the rheology of suspensions and granular flows can be unified, and this unification is used to characterize suspensions with non-negligible particle i

Concentrations of aerosol particles in Poland and their sources are rarely discussed in peer-reviewed journal articles despite serious air quality issues. A source apportionment of carbonaceous aerosol particles was performed during winter at a rural background environment field site in north-eastern Poland. Data were used of light absorption at seven wavelengths and levoglucosan concentrations al

Precision agriculture and Unmanned Aerial Vehicles (UAV) are revolutionizing agriculture management methods. Remote sensing data, image analysis and Digital Surface Models derived from Structure from Motion and Multi-View Stereopsis offer new and fast methods to detect the needs of crops, greatly improving crops efficiency. In this study, we present a tool to detect and estimate crop damage after

The diagnosis of tendon injury relies on clinical signs and diagnostic imaging but imaging is subjective and does not always correlate with clinical signs. A molecular marker would potentially offer a sensitive and specific diagnostic tool that could also provide objective assessment of healing for the comparison of different treatments. Cartilage Oligomeric Matrix Protein (COMP) has been used as

Vehicle-to-vehicle (V2V) wireless communications can improve traffic safety at road intersections and enable congestion avoidance. However, detailed knowledge about the wireless propagation channel is needed for the development and realistic assessment of V2V communication systems. We present a novel geometry-based stochastic MIMO channel model with support for frequencies in the band of 5.2-6.2 G

Congenital muscular dystrophy with laminin α2 chain-deficiency (LAMA2-CMD) is a severe neuromuscular disorder without a cure. Using transcriptome and proteome profiling as well as functional assays, we previously demonstrated significant metabolic impairment in skeletal muscle from LAMA2-CMD patients and mouse models. Reactive oxygen species (ROS) increase when oxygen homeostasis is not maintained

Growing seal populations are examples of successful marine management, and the seals are often seen as a symbol of a thriving ecosystem. However, seals are well known to interact with local small-scale fisheries by feeding from the gears. This causes both lost catches and broken gear, which negatively affect the economic viability of the small-scale fisheries. While lost catches are known to be su

The introduction of paid holidays during the interwar years democratized travel and laid the foundation for modern mass tourism. In European democracies, the right to paid leave found supporters from across the political spectrum who viewed it a means to improve the health of the labor force, increase industrial output, and safeguard family values. Workers also gained new leisure opportunities in

SUMMARY: Antibody repertoires reveal insights into the biology of the adaptive immune system and empower diagnostics and therapeutics. There are currently multiple tools available for the annotation of antibody sequences. All downstream analyses such as choosing lead drug candidates depend on the correct annotation of these sequences; however, a thorough comparison of the performance of these tool

In this study, a two-dimensional model including the governing equations of mass, momentum, species, energy and charge, is developed and then applied to investigate the performance and multiphysics transport processes of solid oxide fuel cells with counter-flow arrangement. The current density and power density are calculated and presented, and the distributions of species and temperature are also
