Professional Mobility as a Model for Overcoming Maladaptive Forms of a Person’s Psychological Defence in Conditions of Professional Development Crises

The article deals with the results of the analysis of the person’s professional mobility as a comprehensive tool for overcoming the professional crises. It also determines the existence of many unascertained psychological problems in its structure. One of these problems is the problem of overcoming maladaptive forms of a person’s psychological defence based on his professional mobility in stressful conditions of the professional development crises. Stressful uncertainty in the professional crisis and the high ambivalent tension, which the person is experiencing, characterize the specialist’s maladaptive development according to the “catastrophic” scenario. In the conditions of the professional development crisis a specialist cannot leave it adaptively and flexibly due to a limited number of rigidly patterned professional barriers and behaviour models. Such maladaptive patterned movement of a specialist towards the disintegrational destruction of the whole system of his professional development can be overcome constructively on the basis of his professional mobility model, selection and realization of the further professional movement vector. We consider the interactive strategy of a specialist’s behaviour for constructive overcoming professional crises in the system of his professional development, based on the development of the ability of directed transitions to new professional movement trajectories in the points of the system bifurcation, as the professional mobility.

A spiking neural network model of the Superior Colliculus that is robust to changes in the spatial-temporal input

Previous studies have indicated that the location of a large neural population in the Superior Colliculus (SC) motor map specifies the amplitude and direction of the saccadic eye-movement vector, while the saccade trajectory and velocity profile are encoded by the population firing rates. We recently proposed a simple spiking neural network model of the SC motor map, based on linear summation of individual spike effects of each recruited neuron, which accounts for many of the observed properties of SC cells in relation to the ensuing eye movement. However, in the model, the cortical input was kept invariant across different saccades. Electrical microstimulation and reversible lesion studies have demonstrated that the saccade properties are quite robust against large changes in supra-threshold SC activation, but that saccade amplitude and peak eye-velocity systematically decrease at low input strengths. These features are not accounted for by the linear spike-vector summation model. Here we show that the model’s input projection strengths and intra-collicular lateral connections can be tuned to generate saccades that follow the experimental results.

Influence of water vapor distribution on the simulated track of Typhoon Hato (2017)

Predicting tropical cyclone (TCs) tracks is a primary concern in TC forecasting. Some TCs appear to move in a direction favorable for their development, beyond the influence of the steering flow. Thus, we hypothesize that TCs move toward regions with high water-vapor content in the lower atmosphere. In this study, four numerical experiments, including a control experiment and three sensitivity experiments, were performed using the Weather Research and Forecasting Model, to analyze the relationship between water vapor distribution and the track of Severe Typhoon Hato (2017). Observations validated the features reproduced in the control experiment. The sensitivity experiments were conducted to explore variations in the TC track under different water vapor environments. Results indicate that the horizontal distribution of water-vapor content exerted a greater impact on the TC track than the steering flow when both factors were significant. Further analysis revealed that the TC’s movement vector was between the direction of the steering flow and the direction toward the peak of vorticity increasing area. The peaks of vorticity increasing area were close to the peaks of water vapor increasing area, which also proved the effect of water vapor distribution on the TC track. These results are expected to improve TC track analysis and forecasting.

DETERMINATION OF RATIONAL PARAMETERS OF SUPPORTING STRUCTURES MADE OF SOIL-CEMENT PILES ON LANDSLIDE-PRONE SLOPES

Purpose. The article proposes a method for determining the rational parameters of supporting structures made of soil-cement piles on landslide-prone slopes. Methodology. To achieve this purpose, the authors performed comparative calculations of finite-element models of landslide-prone layered slope with the arrangement of supporting structures of soil-cement piles: vertical, located at an angle to the vertical axis, combined with a concrete grillage, without grillage, with different diameters, with different distances between piles, but of the same length, which is justified by the location determined by preliminary calculations of the sliding surface. Findings. According to the results of calculating the contact problem of the interaction of the soil mass and the supporting structure, the regularities of formation of strength and stability of the reinforced landslide-prone slope were obtained, which makes it possible to predict its geomechanical stability depending on the possible location of the sliding surface curve. The method of increasing the stability coefficient of the soil slope depending on the variation of the parameters of the soil-cement supporting pile structure is substantiated. Numerical calculations substantiate the parameters of soil-cement pile supporting structures – the length of the piles, their diameter, the distance between the piles, the angle of their inclination and the feasibility of combining the piles with a concrete grillage. Originality. For the first time, the formation regularities of strength and stability of soil-cement supporting structure for strengthening the landslide-prone slopes are obtained, which makes it possible to predict their geomechanical stability depending on the possible location of the sliding surface curve. For the first time, the dependences of changes in absolute displacements, relative deformations, coefficients of strength, stability, as well as Mises stresses in the elements of supporting structures of soil-cement piles on the angle of their inclination, distance between piles and the presence of a concrete grillage that joins them. Methods for assessing and predicting the landslide danger of soil slopes were further developed, which allowed to substantiate the method of increasing the strength coefficient depending on the variation of the parameters of the soil-cement supporting structure. For the first time, the parameters of the method of increasing the stability of landslide-prone slopes with pile supporting structures based on the complex mathematical and centrifugal modeling using real landslides and similarity criteria are substantiated. Practical value. The authors have developed and patented a method of strengthening landslide slopes with the help of soil-cement piles, combined with a concrete grillage, located perpendicular to the movement vector of the landslide body.

Aeolus / ALADIN data analysis in Korea

<p>The assimilation of the Atmospheric Laser Doppler Instrument (ALADIN) wind profile data is expected to play a significant role in improving the skills of numerical weather prediction model. In this study, we analyze the Aeolus/ALADIN data over Korea region using data obtained by radiosonde, dropsonde and the ground based windprofiler. In addition, we analyze data by comparing with atmospheric movement vector (AMV) derived from the Geostationary Korea Multi Purpose Satellite -2A (GK-2A). The ALADIN wind data within the 150 km from the radiosonde/dropsonde/windprofiler station and within ±60 minutes to their observation time are collocated. The AMV data having the closest altitude to the ALADIN altitude are compared, within the 150 km from the ALADIN observation. With the limited number of collocated data obtained from August 29<sup>th</sup> to September 1<sup>th</sup>, 2019, the comparison results show a rather large discrepancy. In case of the radiosonde, RMSD is estimated to be 2.50 m/s and 2.67 m/s in the Rayleigh channel and the Mie channel, respectively. In case of the AMV, the error statistics varies significantly with the quality index of AMV data. When the quality index of 0.8 is applied to the AMV data, RMSD for the infrared AMV is about 3.36 m/s. In the conference, comparison results of all instruments along with the extended time period are going to be presented.</p>

Visual feature tuning of superior colliculus neural reafferent responses after fixational microsaccades

The primate superior colliculus (SC) is causally involved in microsaccade generation. Moreover, visually-responsive SC neurons across this structure’s topographic map, even at peripheral eccentricities much larger than the tiny microsaccade amplitudes, exhibit significant modulations of evoked response sensitivity when stimuli appear peri-microsaccadically. However, during natural viewing, visual stimuli are normally stably present in the environment and are only shifted on the retina by eye movements. Here we investigated this scenario for the case of microsaccades, asking whether and how SC neurons respond to microsaccade-induced image jitter. We recorded neural activity from two male rhesus macaque monkeys. Within the response field (RF) of a neuron, there was a stable stimulus consisting of a grating of one of three possible spatial frequencies. The grating was stable on the display, but microsaccades periodically jittered the retinotopic RF location over it. We observed clear short-latency visual reafferent responses after microsaccades. These responses were weaker, but earlier (relative to new fixation onset after microsaccade end), than responses to sudden stimulus onsets without microsaccades. The reafferent responses clearly depended on microsaccade amplitude, as well as microsaccade direction relative to grating orientation. Our results indicate that one way for microsaccades to influence vision is through modulating how the spatio-temporal landscape of SC visual neural activity represents stable stimuli in the environment. Such representation strongly depends on the specific pattern of temporal luminance modulations expected from the relative relationship between eye movement vector (size and direction), on the one hand, and spatial visual pattern layout, on the other.Significance statementDespite being diminutive, microsaccades still jitter retinal images. We investigated how such jitter affects superior colliculus (SC) activity. We found that SC neurons exhibit short-latency visual reafferent bursts after microsaccades. These bursts reflect not only the spatial luminance profiles of visual patterns, but also how such profiles are shifted by eye movement size and direction. These results indicate that the SC continuously represents visual patterns, even as they are jittered by the smallest possible saccades.

Vector-Mediated Transport Producing Drug-like Peptides

Drugs that are structural mimetics of peptides (e.g. small molecules) have been plagued by problems associated with oral availability and transcellular movement. Vector-mediated transport, where a potentially therapeutic drug is covalently linked to another molecule that is a ligand for an active transport or transcytosis system, was developed as an approach for moving a drug across the blood-brain-barrier. We now report a vector approach that produced peptides with oral activity, blood-brain-barrier transport, and extended in vivo half-life. Generating these properties requires secondary structure stabilization into a β hairpin, and the addition of a C-terminal dipeptide sequence composed of non-polar residues. Peptides with biological activity incompatible with these derivatizations were covalently linked to a model transport vector, producing a chimera with the therapeutic activity of the peptide and the transport properties of the vector. Our platform technology may be a general approach for the design of drug-like peptides.
