Annotation. The use of a constitutional approach makes it possible to study the individual characteristics of the organism at various levels. To harmonize various aspects of the constitution, the principle of integrity is used, which is characterized by multidimensionality, complexity and the study of the peculiarities of correlations. The purpose of the study is to establish and analyze the features of correlations between anthropo-somatotypological indicators and indicators of personality characteristics of practically healthy Ukrainian women of endomosomorphic somatotype. From the database of materials of the research center of National Pirogov Memorial Medical University, Vinnytsya selected primary indicators of personality traits and anthropo-somatotypological indicators of 22 practically healthy Ukrainian women of the first mature age of endomosomorphic somatotype. The analysis of correlations between these indicators was performed in the licensed package "Statistica 6.1" using the non-parametric Spearman's method. In women of endomosomorphic somatotype, the following multiple reliable and medium-strength unreliable connections were established: direct (r = from 0.30 to 0.59) index on the Eysenck insincerity scale with all indicators of the width of the distal epiphyses (WDE) of the extremities, most skin folds thicknesses (TSFF) of the upper extremity, endo- and mesomorphic components of the somatotype and fat and bone indicators of the component composition of body weight; direct (r = from 0.34 to 0.56) Eysenck extraversion-introversion index with most transverse torso dimensions; direct (r = from 0.32 to 0.53) Spielberger personal anxiety index with almost half of the cephalometric parameters and torso size and most pelvic size; direct (r = from 0.30 to 0.64) Shmishek stunt type accentuation index with body weight, half longitudinal, circumferential dimensions and TSFF indicators, endomorphic component of somatotype and fat and muscle indicators of body mass component composition; inverse (r = from -0.32 to -0.47) Shmishek emotional character accentuation index with all longitudinal dimensions, half of the indicators of WDE of the extremities, most indicators of TSFF of the upper extremity and bone index of the component composition of body weight; inverse (r = from -0.31 to -0.45) Shmishek anxiety type accentuation index with the majority of extremities and TSFF indicators, endo- and mesomorphic components of somatotype and fat and bone indicators of body weight component composition; inverse (r = from -0.46 to -0.63) indicator of accentuation of the character of the demonstrative type according to Shmishek with the majority of indicators of TSFF of the upper extremity; direct (r = from 0.31 to 0.61) Shmishek excitatory character accentuation index with most longitudinal dimensions, upper extremity WDE, almost half of TSFF, endomorphic somatotype component and all indicators of body weight component composition; inverse (r = from -0.30 to -0.40) Shmishek dysthymic character accentuation index with half of longitudinal dimensions, ectomorphic component of somatotype and bone index of body mass component composition; inverse (r = -0.30 to -0.75), indicators of the level of subjective control in the field of achievement and family relations according to Rotter with half the girth, half the transverse dimensions of the torso and pelvis and muscle component of body weight; direct (r = from 0.34 to 0.61) indicators of the level of subjective control in the field of failures and educational (professional) relations according to Rotter with most longitudinal dimensions, WDE of the upper extremities (only with the level of subjective control in the field of educational (professional) relations) and bone index of the component composition of body weight. As a result of quantitative analysis of reliable and unreliable average correlations of personality indicators with anthropo-somatotypological indicators of women of endomosomorphic somatotype, the highest relative percentage of relationships between: leading typological characteristics of temperament according to Eysenck and WDE extremities; psychodynamic features of personality according to Spielberger and cephalometric indicators and transverse dimensions of the body; indicators of severity and features of accentuated personality traits according to Shmishek and longitudinal body size, WDE limbs and TSFF; indicators of the level of subjective control over Rotter and the longitudinal dimensions of the body and WDE of the extremities.

Abstract. Studies of the global sea-level budget (SLB) and the global ocean-mass budget (OMB) are essential to assess the reliability of our knowledge of sea-level change and its contributions. Here we present datasets for times series of the SLB and OMB elements developed in the framework of ESA's Climate Change Initiative. We use these datasets to assess the SLB and the OMB simultaneously, utilising a consistent framework of uncertainty characterisation. The time series, given at monthly sampling, include global mean sea-level (GMSL) anomalies from satellite altimetry; the global mean steric component from Argo drifter data with incorporation of sea surface temperature data; the ocean mass component from Gravity Recovery and Climate Experiment (GRACE) satellite gravimetry; the contribution from global glacier mass changes assessed by a global glacier model; the contribution from Greenland Ice Sheet and Antarctic Ice Sheet mass changes, assessed from satellite radar altimetry and from GRACE; and the contribution from land water storage anomalies assessed by the WaterGAP global hydrological model. Over the period Jan 1993–Dec 2016 (P1, covered by the satellite altimetry records), the mean rate (linear trend) of GMSL is 3.05 ± 0.24 mm yr−1. The steric component is 1.15 ± 0.12 mm yr−1 (38 % of the GMSL trend) and the mass component is 1.75 ± 0.12 mm yr−1 (57 %). The mass component includes 0.64 ± 0.03 mm yr−1 (21 % of the GMSL trend) from glaciers outside Greenland and Antarctica, 0.60 ± 0.04 mm yr−1 (20 %) from Greenland, 0.19 ± 0.04 mm yr−1 (6 %) from Antarctica, and 0.32 ± 0.10 mm yr−1 (10 %) from changes of land water storage. In the period Jan 2003–Aug 2016 (P2, covered by GRACE and the Argo drifter system), GMSL rise is higher than in P1 at 3.64 ± 0.26 mm yr−1. This is due to an increase of the mass contributions (now about 2.22 ± 0.15 mm yr−1, 61 % of the GMSL trend), with the largest increase contributed from Greenland. The SLB of linear trends is closed for P1 and P2, that is, the GMSL trend agrees with the sum of the steric and mass components within their combined uncertainties. The OMB budget, which can be evaluated only for P2, is also closed, that is, the GRACE-based ocean-mass trend agrees with the sum of assessed mass contributions within uncertainties. Combined uncertainties (1-sigma) of the elements involved in the budgets are between 0.26 and 0.40 mm yr−1, about 10 % of GMSL rise. Interannual variations that overlie the long-term trends are coherently represented by the elements of the SLB and the OMB. Even at the level of monthly anomalies the budgets are closed within uncertainties, while also indicating possible origins of remaining misclosures.

This chapter studies the presence of “subliminal matter.” The presence of significant mass in subluminal matter was first suggested in the 1930s by the surprisingly large velocities of galaxies in clusters of galaxies. The chapter traces the history of discovery of astronomical evidence of subluminal matter in large clusters of galaxies, in groups of a few or just two galaxies that are close enough that they seem likely to be gravitationally bound, and in individual spiral galaxies. There must be enough mass in spirals to account for the circular velocities of disk stars, and the mass rotationally supported in the disk must be large enough that gravity can form spiral arms, but this mass component cannot be so large that the spiral arms grow to destroy the observed nearly circular motions in the disk. These conditions require that most of the mass in a spiral galaxy is in a stable subluminal massive halo draped around the outskirts of the luminous parts of the galaxy.

AbstractPolygenic risk models have led to significant advances in understanding complex diseases and their clinical presentation. While models like polygenic risk scores (PRS) can effectively predict outcomes, they do not generally account for disease subtypes or pathways which underlie within-trait diversity. Here, we introduce a latent factor model of genetic risk based on components from Decomposition of Genetic Associations (DeGAs), which we call the DeGAs polygenic risk score (dPRS). We compute DeGAs using genetic associations for 977 traits in the UK Biobank and find that dPRS performs comparably to standard PRS while offering greater interpretability. We show how to decompose an individual’s genetic risk for a trait across DeGAs components, highlighting specific results for body mass index (BMI), myocardial infarction (heart attack), and gout in 337,151 white British individuals, with replication in a further set of 25,486 non-British white individuals from the Biobank. We find that BMI polygenic risk factorizes into components relating to fat-free mass, fat mass, and overall health indicators like physical activity measures. Most individuals with high dPRS for BMI have strong contributions from both a fat mass component and a fat-free mass component, whereas a few ‘outlier’ individuals have strong contributions from only one of the two components. Overall, our method enables fine-scale interpretation of the drivers of genetic risk for complex traits.

Abstract 1SWASP J161335.80$-$284722.2 (hereafter J161335) is an eclipsing red-dwarf binary with an orbital period of $0.229778\:$d, which is around the short-period limit for contact binaries. Three sets of multi-color light curves of J161335 were obtained from different telescopes in 2015 and 2016 and are analyzed using the Wilson–Devinney method. We discovered that the system is a W-type contact system with a contact degree of 19% and a high mass ratio of 0.91. By using all available eclipse times, we found that the observed $-$ calculated $(O-C)$ diagram displays a cyclic oscillation with an amplitude of 0.00196($\pm 0.00006)\:$d and a period of 4.79($\pm 0.14)\:$yr while it undergoes a downward parabolic change. This downward variation corresponds to a continuous decrease in the orbital period at a rate of $dP/dt = -4.26(\pm$0.01) $\times$ 10$^{-7}\:$d$\:$yr$^{-1}$. The small-amplitude oscillation is explained as the light travel-time effect from the gravitational influence of a third body with a lowest mass of $M _{3}$ = 0.15($\pm 0.01)M_{\,\odot }$. In solving the light curves, we found that the third light is increasing, with the wavelength suggesting that the third body may be a cool red dwarf. This is in agreement with the results obtained by analyzing the $O-C$ diagram. The tertiary red dwarf is orbiting the central red-dwarf binary at an orbital separation of 2.8($\pm 0.2$) au. These results suggest that the J161335 system may be formed through early dynamical interaction where the original low-mass component was replaced by a higher-mass third body and the lower-mass component was kicked out to a wider orbit. In this way, a hierarchical triple system similar to J161335 with a high-mass-ratio binary and a small close-in third body is formed.

AbstractWe investigate the stellar and dynamical mass profiles of 32 brightest cluster galaxies (BCGs, MK = −25.7 to −27.8 mag) in massive clusters (0.05 < z < 0.30), and in particular the rising velocity dispersion profiles of 23 of these BCGs found in Loubser et al. (2018). We make comprehensive measurements of the Gauss-Hermite higher order velocity moments h3 and h4, and find positive central values for h4 for all the BCGs. We model the stellar and dynamical mass profiles of 25 of the BCGs using the Multi-Gaussian Expansion (MGE) and Jeans Anisotropic Method (JAM) for an axisymmetric case, deriving the stellar mass-to-light ratio (ϒ*DYN), and anisotropy (βz). We further explicitly add a dark matter halo mass component (MDM within r200) which we constrain from weak lensing results. In this proceedings, we summarise the study and show an example of the results.

AbstractWe aim to analyse the co-added Herschel images of various categories of evolved stars in the LMC and SMC from the Herschel HERITAGE survey in order to identify, in a statistical sense, a cool historic dust mass component emitted by these sources. The fluxes derived from the co-added stacks can then be compared with those predicted by the GRAMS model grid in order to refine the DPRs estimated for the SMC and LMC.

The general field, containing all the macroscopic fields in it, is divided into the mass component, the source of which is the mass four-current, and the charge component, the source of which is the charge four-current. The mass component includes the gravitational field, acceleration field, pressure field, dissipation field, strong interaction and weak interaction fields, other vector fields. The charge component of the general field represents the electromagnetic field. With the help of the principle of least action we derived the field equations, the equation of the matter’s motion in the general field, the equation for the metric, the energy and momentum of the system of matter and its fields, and calibrated the cosmological constant. The general field components are related to the corresponding vacuum field components so that the vacuum field generates the general field at the macroscopic level.
