The surface electromyographic (sEMG) signal that originates in the muscle is inevitably contaminated by various noise signals or artifacts that originate at the skin-electrode interface, in the electronics that amplifies the signals, and in external sources. Modern technology is substantially immune to some of these noises, but not to the baseline noise and(More)
We investigated the influence of inter-electrode spacing on the degree of crosstalk contamination in surface electromyographic (sEMG) signals in the tibialis anterior (target muscle), generated by the triceps surae (crosstalk muscle), using bar and disk electrode arrays. The degree of crosstalk contamination was assessed for voluntary constant-force(More)
The paper investigates methods for intrinsic plagiarism detection and author diarization. We developed a plagiarism detection method based on constructing an author style function from features of text sentences and detecting outliers. We adapted the method for the diarization problem by segmenting author style statistics on text parts, which correspond to(More)
Chiral sorbents for HPLC separation of optical isomers carrying glycopeptide antibiotics (eremomycin or its eremosaminyl aglycon, ristomycin, or vancomycin) fixed onto the surface of silica gel have been synthesized. The patterns of the retention and separation of profen isomers and their dependence on the nature of the chiral selector and the eluant(More)
Sorting tuples by an attribute value is a common search scenario and many search engines support such capabilities, e.g. price-based sorting in e-commerce, time-based sorting on a job or social media website. However, sorting purely by the attribute value might lead to poor user experience because the relevance is not taken into account. Hence, at the top(More)
Quantitative characteristics of organic carbon stock and distribution in the main ecosystem blocks and production-destruction processes in the soil-phytocenosis system have been evaluated in wet oldgrowth bilberry-sphagnum forest. It has been shown that equivalent amounts of carbon are accumulated in the soil and plant reservoirs of the ecosystem and that(More)
In patients with parkinsonism to whom in accordance with medical-diagnostic indices electrodes were implanted into the nuclei of thalamus and striopallidal system, impulse activity of neurones was recorded in tests with presentation of visual and acoustic stimuli. It has been shown that neurones of these structures, reacting by a change of discharges(More)
The paper presents a method of constructing a supervised topic model of a major conference. The supervised part is the expert information about document-topic correspondence. To exploit the expert information we use a regularization term which penalizes difference between a constructed and an expert-given model. To find optimal parameters we add the(More)
The experiments with visible light or 0.85 [L light on coupled waveguides and waveguide interferometers fabricated in LiNbO 3 are plagued by the photorefractive effect, in particular if optical nonlinearities in these waveguides are used intentionally, as in the all-optical waveguide modulator.' In her experiments on optical waveguide interferometers, A.(More)
