“…The explosive growth in the number of smartphone users provides the opportunity to develop a hand tracking method for epidemiological studies of perception (primary cognitive functions), taking into account regional, age, gender, social and other stratification of populations. The presence of embedded sensors in smartphones allows one to create special software applications [17,23] that implement visual and audial perceptual tests. Moreover, some widely used applications and smartphone options can be modified into a perceptual test involuntary performed by the user (at his/her discretion).…”

“…The above rationale was used for the development of a manual tracking system [16,17] that allowed us to measure in real time the quantitative parameters of perception of audial and visual stimuli. The proposed HSC Hand tracker also provides for formation of a wide variety of audial stimuli and modes of their presentation: a tonal or noise sound varying in its volume; a frequency-varying tonal sound; a sequence of paired sound pulses with a variable interpulse interval and a variable intensity, a binaural sequence of sound…”

Here, we propose an all-instrumental objective method (hand tracking) for the real time quantification of perception of stimuli presented in various modalities. The method is based on measuring the dynamic error of performance by a subject of motor control over a real or virtual (computer generated) stimulus with the help of a contactless manipulator. The method got its name from its previous analogue-the eye tracking; in both cases, the measurement of psychophysiological characteristics of the subject is carried out by monitoring the parameters of his/her motor activities. The above principle has been implemented in the form of a hardware-software complex Hand tracker, which has been tested for the ability to perceive the "segment orientation angle" and "figure color against the background" virtual stimuli. With the first stimulus, individual diagrams of perception accuracy were obtained in healthy subjects who were asked to guess the segment inclination angle. The results allowed us to identify the parameters of the neural model simulating the respective primary recognizer. With the second visual stimulus, we found that in patients with focal brain lesions, the thresholds of color differentiation were abnormally high and, unlike the normal ones, did not depend on the semantic content of the stimulus. Since the Hand tracker provides for the simultaneous control over several (up to eight) independent parameters of audial and visual stimuli, the proposed method can be used in studying the intermodal connections and/or the collective behavior, when different team members control different parameters of the stimulus, trying to solve a common problem. The article also addresses the prospect of implementing the hand tracking method in the form of special applications for smartphones with embedded movement sensors. Such a portable device could be used for epidemiological studies of perception (primary cognitive functions) to elucidate the age-and gender-related, regional, social and other stratification of populations.

The article presents the results of studying the effectiveness of options for biologizing the fertilization system and related factors of the impact of options for using post-harvest green manure in the technology of growing grain corn on gray forest and chernozem soils. The effectiveness of the use of cruciferous green manure crops, such as white mustard, oil radish and spring rape, has been investigated. Evaluation of the effectiveness of green manure was carried out both by the species factor and by the method of sowing green manure plants, in particular, the usual row and wide-row methods. The features of the influence of late autumn post-harvest green manure on the formation of agrophysical soil properties, such as the duty cycle in its categories and soil density, taking into account the optimization of the air properties of the soil and the restoration of its structure in the technologies of adaptive cultivation of agricultural crops, have been studied. The role of green manure crops in providing herbicide-free control of the level of weed infestation was assessed both from the standpoint of controlling the number of various types of weeds and from the standpoint of regulating their development and prevalence. The formation of segetal vegetation in crops of corn for grain was investigated in the format of determining the effectiveness of the aftereffect of green manure on the formation of the level of weediness in the late phenological phases of growth and development of corn. The features of the formation of leafy mass of green manure were investigated, taking into account the temperature and moisture regime.Based on this, an assessment was made of the adaptability of various types of green manure crops depending on the limiting factors of moisture and low temperatures in the variant of summer-autumn use. Conclusions are made about the expediency of using this criterion of the studied cruciferous crops. The influence of green manure crops on the formation of corn yield for grain is shown, taking into account different types of soils and their fertility potential, as well as taking into account the method of sowing green manure. Increases in corn yield were determined in comparison with unfertilized control and their level was assessed in relation to a possible effective alternative replacement of existing options for fertilizing corn with grain. Conclusions are made about the most productive green manure option based on cruciferous species, and prospects for further research and problematic aspects of the use of cruciferous green manure plants are outlined.
