Internal scheme of the body assessment in an experiment with environmental uncertainty

The aim of the work was to analyze the influence of various environmental factors forming environmental uncertainty on the nature of the transformation of the "internal scheme of the body". Materials and methods. For the study, a group of healthy volunteers (n = 90) was selected. The results in this paper are median, 75 and 25 percentiles (Me [UQ / LQ]). The study was conducted in several stages. At the first stage, the criteria for excluding potential participants from the experiment were formed. At the second stage of the study, a video analysis of the main anatomical orientations of the pelvic region in static and dynamic samples was conducted for all participants. Conclusion. In the course of the study, specific patterns of spatial deviations of biomechanical blocks of the pelvic region were established, triggered by changes in the qualitative and quantitative parameters of the external environment. So, in conditions of static equilibrium, coordination is activated with involvement of the anterior and posterior half-rings of the pelvis (frontal biomechanical blocks); in conditions of dynamic equilibrium, diagonal biomechanical blocks of the pelvic region are activated; in conditions of deprivation of visual afferentation, the compensatory reactions of the lateral semirings of the pelvic region (lateral biomechanical blocks) are formed

ценка двигательной адаптации здоровых лиц по данным пространственно-временной кинематики

An important problem of modern clinical biomechanics is to identify complex movement markers that make it possible to evaluate complex motor adaptive reactions regardless of age, gender, and anthropometric deviations. The purpose of the present study was to develop a method for analysis of human motor adaptive reactions based on calculating specific biomechanical markers obtained by performing diverse kinematic tests. The study involved 90 volunteers with a right-leading kinematic side at an age of 18.8 [16.8/20.8] years, with a height of 171.8 [179.2/164.8] cm, a body weight of 65.3 [76.6/58.5] kg, and the ratio of men and women – 5 : 4. During the study, all participants underwent biomechanical analysis using the TESLASUIT remote motion capture suit and performing diverse kinematic tests. In the course of the study, a new method for analyzing human motor adaptive reactions was developed. It is based on calculating specific time markers of the active phase, average angular deviation markers, and inertial kinematic markers. All markers are calculated after each kinematic tests “frontal stability”, “sagittal stability”, “spatial orientation”, and “stimulus identification”. Our survey revealed that specific (p < 0.001) markers of the first test are the time indicators of the active phase, the markers of the second and fourth tests are associated with the average angular deviation parameters, and the specific indicators of the third test can be the inertial kinematics of thighs, legs, and feet.Актуальной проблемой современной клинической биомеханики остается выделение маркеров сложных движений, позволяющих оценивать сложные двигательные приспособительные реакции вне зависимости от возраста, пола и антропометрических девиаций. Цель исследования: разработать метод анализа двигательных приспособительных реакций человека по биомеханическим маркерам, полученным при выполнении разноплановых кинематических тестов. В исследовании приняли участие 90 добровольцев с правосторонним ведущим кинематическим звеном в возрасте 18,8 [16,8/20,8] лет, с ростом 171,8 [179,2/164,8] см и массой тела 65,3 [76,6/58,5] кг, соотношение мужчин и женщин – 5 : 4. В ходе исследования всем участникам проводили биомеханический анализ с применением системы дистанционного захвата движений «TESLASUIT», а также выполняли разноплановые кинематические тесты. В ходе проведения исследования разработан новый метод анализа двигательных приспособительных реакций человека, основанный на вычислении специфических маркеров времени активной фазы средней угловой девиации и инерциальной кинематики при выполнении стандартизированных кинематических тестов «фронтальная стабильность», «сагиттальная стабильность», «пространственная ориентация» и «идентификация стимула». Установлено, что специфическими (р < 0,001) маркерами первого теста являются показатели времени активной фазы, маркеры второго и четвертого тестов связаны с параметрами средней угловой девиации, специфическими индикаторами третьего теста может выступать инерциальная кинематика бедер, голеней и стоп

Development and large volume production of extremely high current density YBa₂Cu₃O₇ superconducting wires for fusion

The fusion power density produced in a tokamak is proportional to its magnetic field strength to the fourth power. Second-generation high temperature superconductor (2G HTS) wires demonstrate remarkable engineering current density (averaged over the full wire), JE, at very high magnetic fields, driving progress in fusion and other applications. The key challenge for HTS wires has been to offer an acceptable combination of high and consistent superconducting performance in high magnetic fields, high volume supply, and low price. Here we report a very high and reproducible JE in practical HTS wires based on a simple YBa2Cu3O7 (YBCO) superconductor formulation with Y2O3 nanoparticles, which have been delivered in just nine months to a commercial fusion customer in the largest-volume order the HTS industry has seen to date. We demonstrate a novel YBCO superconductor formulation without the c-axis correlated nano-columnar defects that are widely believed to be prerequisite for high in-field performance. The simplicity of this new formulation allows robust and scalable manufacturing, providing, for the first time, large volumes of consistently high performance wire, and the economies of scale necessary to lower HTS wire prices to a level acceptable for fusion and ultimately for the widespread commercial adoption of HTS
