description: In brane world models, combining the extra dimensional field modes with the standard four dimensional ones yields interesting physical consequences that have been proved from high energy physics to cosmology. Even some low energy phenomena have been considered along these lines to set bounds on the brane model parameters. In this work we extend to the gravitational realm a previous result which gave finite electromagnetic and scalar potentials and self energies for a source looking pointlike to an observer sitting in a 4D Minkowski subspace of the single brane of a Randall-Sundrum spacetime including compact dimensions. We calculate here the gravitational field for the same type of source by solving the linearized Einstein equations. Remarkably, it turns out to be also non singular. Moreover, we use gravitational experimental results of the Cavendish type and the Parameterized Post Newtonian (PPN) coefficients, to look for admissible values of the brane model parameters. The anti de Sitter radius hereby obtained is concordant with previous results based on Lamb shift in hydrogen. However, the resulting PPN parameters lie outside the acceptable value domain.

description: Diffusive operations, which mix the populations of different elements of phase space, can irreversibly transform a given initial state into any of a spectrum of different states from which no further energy can be extracted through diffusive operations. We call these ground states. The lower bound of accessible ground state energies represents the maximal possible release of energy. This lower bound, sometimes called the diffusively accessible free energy, is of interest in theories of instabilities and wave-particle interactions. On the other hand, the upper bound of accessible ground state energies has escaped identification as a problem of interest. Yet, as demonstrated here, in the case of a continuous system, it is precisely this upper bound that corresponds to the paradigmatic "quasilinear plateau" ground state of the bump-on-tail distribution. Although for general discrete systems the complexity of calculating the upper bound grows rapidly with the number of states, using techniques adapted from treatments of the lower bound, the upper bound can in fact be computed directly for the three-state discrete system.

Citizen Science

description: VERA - Virtual Ecosystem for Research Activation is an online platform built in the framework of the EU funded project COESO. ”Activation” is the key word to remember from this acronym. One important strategy for activating research is for society members to be proactively involved in co-creating it. But how? There is a need to bridge society with research, and that is what VERA is doing. VERA is a hub where researchers and key society stakeholders (community-based organizations, experts of practice, service providers, politicians, journalists, etc.) can meet and collaborate to identify and solve societal issues through SSH (social science and humanities)-focused citizen science, thereby opening research to the public. Within the VERA platform, society members and researchers alike can create a personal profile to find others who are interested in the same topics and build research teams and projects together. When society and research are bridged, collaborations are enabled, innovative methodologies are created, and solutions to relevant issues are discovered. The design and development of VERA were the result of an intense collaboration itself. The platform was in fact co-designed involving the SSH citizen science community from the very beginning. Furthermore, VERA is interoperable by design; it is currently integrated with EUCitizen.Science, GoTRIPLE and Fundit platform to support project's visibility, identification of potential collaborators and relevant researchers and to identify funding opportunities. Keywords: citizen science, collaborative platforms.

description: Fracture in laminated composites is typically caused by inter-laminar damage, such as delamination, promoted by or coexisting with intra-laminar damage, like matrix-cracking and fibre failure. During operation of composite structures, these damage mechanisms initiate and propagate under variable amplitude loading conditions that are very different from the constant amplitude loading conditions applied to test specimens in laboratories to characterise fatigue properties of the material. The work in Task 5.4 focuses on the effect of variable amplitude loading on the damage evolution in fiber reinforced polymer laminated composites. An experimental test campaign investigates fatigue-driven delamination under multi-level block loading, and a new crack growth rate model is proposed. The crack growth rate model is included in a finite element formulation as an extension of the inter-laminar fatigue damage method from Task 5.1. The method has been implemented in the Simcenter Samcef software. The simulated results from the Simcenter Samcef solver show a significant improvement in the delamination growth prediction in comparison to the conventional non-interaction crack growth rate model. Another experimental campaign investigates intra-laminar damage under two-level block loading. The experiments subject specimens to flexural fatigue loading using a simplified test configuration that can be readily implemented by most any research group with access to a universal fatigue testing machine. The simplified experimental setup used in this work was suitable to investigate the load history effects on intralaminar damage evolution.

description: We have obtained a deep, simultaneous observation of the bright, nearby Seyfert galaxy IC 4329A with Suzaku and NuSTAR. Through a detailed spectral analysis, we are able to robustly separate the continuum, absorption and distant reflection components in the spectrum. The absorbing column is found to be modest at $N_H = 6 \times 10^{21}$ cm$^2$, and does not introduce any significant curvature in the Fe K band. We are able to place a strong constraint on the presence of a broadened Fe Kα line: $E = 6.46^{+0.08}_{-0.07}$ keV rest frame with $σ = 0.33^{+0.08}_{-0.07}$ keV and $EW = 34^{+8}_{-7}$ eV, though we are not able to constrain any of the parameters of a relativistic reflection model. These results highlight the range in broad Fe Kα line strengths observed in nearby, bright AGN (roughly an order of magnitude), and imply a corresponding range in the physical properties of the inner accretion disk in these sources. We have also updated our previously reported measurement of the high-energy cutoff of the hard X-ray emission using both observatories rather than just NuSTAR alone: $E_{cut} = 186 \pm 14$ keV. This high-energy cutoff acts as a proxy for the temperature of the coronal electron plasma, enabling us to further separate this parameter from the optical depth of the plasma and to update our results for these parameters as well. We derive $kT = 50^{+6}_{-3}$ keV with $τ = 2.34^{+0.16}_{-0.11}$ using a spherical geometry, $kT = 61 \pm 1$ keV with $τ = 0.68 \pm 0.02$ for a slab geometry, with both having an equivalent goodness-of-fit.

Magic Realism

description: This Masters thesis includes two interrelated components: a creative work and an exegesis. The creative component is a collection of theoretically informed short stories entitled ‘Myths, Moths, Mum and Me’. This fictional narrative follows the events in the life of a post-55-year-old woman in contemporary Australian society and, through this narrative, attempts to provide points of cultural identification that will lead to further discussion for, and about, this community of Australian women. This discontinuous narrative combines a realist style influenced by the genre of Magic Realism and was chosen in an attempt to provide a writerly, perceptive and honest presentation of the issues facing this generation of women. Written to accompany ‘Myths, Moths, Mum and Me’, the Masters-level exegetical dissertation investigates the culture of two generations of women – the contemporary post-55-year-old woman and her mother – and the reasons behind their differences, together with the current social situation experienced by many mature-aged women, including the contributing circumstances which have led to a lack of preparation for their mature age. This exegesis discusses the practice-led research methodology and resulting outcomes that inform and underpin the themes, narrative construction and literary devices chosen to develop and produce the accompanying collection of short stories. By extending the scholarship relating to the generation of contemporary post-55-year-old women in Australian society, it is hoped this exegesis will be useful for creators and consumers of, as well as commentators on, the cultural identity of the mature aged woman in Australian society as it contextualises and addresses current issues facing this demographic.

description: This work investigates the linearisation strategies used by speakers when describing real-world scenes to better understand production plans for multi-utterance sequences. In this study, 30 participants described real-world scenes aloud. To investigate which semantic features of scenes predict order of mention, we quantified three features (meaning, graspability, and interactability) using two techniques (whole-object ratings and feature map values). We found that object-level semantic features, namely those affordance-based, predicted order of mention in a scene description task. Our findings provide the first evidence for an object-related semantic feature that guides linguistic ordering decisions and offers theoretical support for the role of object semantics in scene viewing and description.

description: In recent years, neuroscientists have been interested to the development of brain-computer interface (BCI) devices. Patients with motor disorders may benefit from BCIs as a means of communication and for the restoration of motor functions. Electroencephalography (EEG) is one of most used for evaluating the neuronal activity. In many computer vision applications, deep neural networks (DNN) show significant advantages. Towards to ultimate usage of DNN, we present here a shallow neural network that uses mainly two convolutional neural network (CNN) layers, with relatively few parameters and fast to learn spectral-temporal features from EEG. We compared this models to three other neural network models with different depths applied to a mental arithmetic task using eye-closed state adapted for patients suffering from motor disorders and a decline in visual functions. Experimental results showed that the shallow CNN model outperformed all the other models and achieved the highest classification accuracy of 90.68%. It's also more robust to deal with cross-subject classification issues: only 3% standard deviation of accuracy instead of 15.6% from conventional method.

description: A theoretically- and clinically-important issue for understanding word retrieval is how speakers resolve conflict during linguistic tasks. This study investigated two types of conflict resolution: prepotent conflict, when one dominant incorrect response must be suppressed; and underdetermined conflict, when multiple reasonable responses compete. The congruency sequence effect paradigm was used to assess trial-to-trial changes in reaction time and accuracy during word production tasks with either prepotent or underdetermined conflict. Pictures were named faster on trials with low-conflict as compared to high-conflict regardless of conflict type. This effect was modulated by the amount of conflict experienced on the previous trial for both tasks. These results suggest that resolution of underdetermined and prepotent conflict may engage the same general cognitive mechanism. This work expands our understanding of the relationship between cognitive control and word production and can inform clinical approaches for people with anomia.

Computational Hip Simulations in Patients with Femoroacetabular Impingement Syndrome during Various Tasks

description: Femoroacetabular impingement syndrome (FAIS) is a clinical hip disorder consisting of imaging findings, clinical signs and symptoms that indicate premature contact between the acetabulum and the proximal femur during hip movements. Although FAIS seems to develop as a result of an abnormal distribution of hip joint loads, there is still little knowledge about the in vivo distribution of HJRF. HJRF can be obtained non-invasively using in silico models. MSK models are among the computational models that can be used to calculate joint forces requiring a shorter simulation time. The current project's goal is to use the software AnyBody Modeling System to implement MSK models and run MSK simulations in order to better understand the relationship between hip kinetics and FAIS. Because different activities require different HJRF, an analysis of hip loads during various tasks (gait, double leg squat, and single leg squat) was performed. For gait and double leg squat tasks, MSK models of 10 FAIS patients and 10 healthy controls were implemented, while MSK models of 8 patients and controls were implemented for single leg squat. The pipeline used to perform MSK simulations was validated using a 5-subject gait dataset from a publication by Moreira et al., which allowed to statistically compare the outputs of the implemented models to their published results using SPM. There were no differences in terms of hip kinematics and kinetics between patients and controls for gait and double leg squat. In the single leg squat, people with FAIS showed lower proximodistal HJRF and flexion HJA compared to healthy controls. In FAIS patients, proximodistal HJRF, flexion HJM, and flexion HJA were found to be lower in the involved leg compared to the uninvolved one. Smaller HJRF and HJM values in FAIS patients may represent a strategy of reduced muscle forces to avoid pain and symptoms during high demand tasks such as the single leg squat. More research is needed to implement more complex MSK models, which may include both subject-specific hip geometry from MRI reconstruction and hip muscle behavior analysis from EMG data.

description: We propose experimental methods to engineer reservoirs at arbitrary temperature which are feasible with current technology. Our results generalize to mixed states the possibility of quantum state engineering through controlled decoherence. Finite temperature engineered reservoirs can lead to the experimental observation of thermal entanglement --the appearance and increase of entanglement with temperature-- to the study of the dependence of finite time disentanglement and revival with temperature, quantum thermodynamical effects, among many other applications, enlarging the comprehension of temperature dependent entanglement properties.

description: After motivating an interest in the shape of the topological charge density spectral function in hot Yang-Mills theories, we estimate it with the help of thermally averaged classical real-time simulations, for $N_{\rm c} = 2,3$. After subtracting a perturbative contribution at large frequencies, we observe a non-trivial shape at small frequencies (a dip rather than a peak), interpolating smoothly towards the sphaleron rate at zero frequency. Possible frequency scales making an appearance in this shape are discussed. Implications for warm axion inflation and reheating, and for imaginary-time lattice measurements of the strong sphaleron rate, are recapitulated.

description: There is an upward trend in the incidence of hypertension which may be causally linked to persistent organic pollutants (POPs) exposure and hormone dysregulation. Acculturation may also play an important role in hormone dysregulation. This dissertation comprised 2,264 adults aged 45-74 years from the Hispanic Community Health Study/Study of Latinos and examined the relationship of POPs exposure, thyroid and sex hormones with transition to prehypertension and hypertension and change in blood pressure (BP) after 6 years of follow-up. We also assessed associations of acculturation and Hispanic/Latino background with hormones. Organochlorine pesticides (OCPs) were associated with transition to prehypertension while both polychlorinated biphenyls and OCPs were associated with transition to hypertension from normotension and prehypertension and with change in BP. In both men and postmenopausal women, we found positive associations of triiodothyronine with change in pulse pressure and transition to hypertension from prehypertension and normotension. Thyroid stimulating hormone was positively associated with transition to hypertension in men and change in diastolic BP in both sexes. We found that sex hormones may operate differently by stage of high BP in both sexes. Dehydroepiandrosterone sulfate was inversely associated with transitioning from normotension to prehypertension in both sexes and with transitioning from prehypertension to hypertension in women. Low estradiol was protective of transitioning to hypertension from prehypertension in women, bioavailable testosterone (T) and T were associated with transitioning from normotension to prehypertension in men while estradiol was protective. Follicle stimulating hormone (FSH), luteinizing hormone (LH), and LH/T ratio were protective of transitioning to hypertension while LH/FSH ratio was positively associated with transitioning to hypertension. Additionally, we found significant differences in hormones by Hispanic/Latino background. Language but not social acculturation, age at immigration, dietary acculturation, and acculturation score from the Multi-Ethnic Study of Atherosclerosis were selectively associated with sex and thyroid hormones in both sexes. Current smoking and sleep apnea syndrome were partial mediators of the relationship between Hispanic/Latino background and triiodothyronine. This dissertation provides a better understanding of the complex multifactorial disease etiology of hypertension. Public health interventions should incorporate early and regular BP monitoring, treatment and education on hypertension prevention and control.

description: These are the proceedings of the Second Workshop on GRAPH Inspection and Traversal Engineering (GRAPHITE 2013), which took place on March 24, 2013 in Rome, Italy, as a satellite event of the 16th European Joint Conferences on Theory and Practice of Software (ETAPS 2013). The topic of the GRAPHITE workshop is graph analysis in all its forms in computer science. Graphs are used to represent data in many application areas, and they are subjected to various computational algorithms in order to acquire the desired information. These graph algorithms tend to have common characteristics, such as duplicate detection to guarantee their termination, independent of their application domain. Over the past few years, it has been shown that the scalability of such algorithms can be dramatically improved by using, e.g., external memory, by exploiting parallel architectures, such as clusters, multi-core CPUs, and graphics processing units, and by using heuristics to guide the search. Novel techniques to further scale graph search algorithms, and new applications of graph search are within the scope of this workshop. Another topic of interest of the event is more related to the structural properties of graphs: which kind of graph characteristics are relevant for a particular application area, and how can these be measured? Finally, any novel way of using graphs for a particular application area is on topic. The goal of this event is to gather scientists from different communities, such as model checking, artificial intelligence planning, game playing, and algorithm engineering, who do research on graph search algorithms, such that awareness of each others' work is increased.

description: Pulsar timing-array correlation measurements offer an exciting opportunity to test the nature of gravity in the cosmologically novel nanohertz gravitational wave regime. The stochastic gravitational wave background is assumed Gaussian and random, while there are limited pulsar pairs in the sky. This brings theoretical uncertainties to the correlation measurements, namely the pulsar variance due to pulsar samplings and the cosmic variance due to Gaussian signals. We demonstrate a straightforward calculation of the mean and the variances on the Hellings-Downs correlation relying on a power spectrum formalism. We keep arbitrary pulsar distances and consider gravitational wave modes beyond Einstein gravity as well as off the light cone throughout, thereby presenting the most general and, most importantly, numerically efficient calculation of the variances.

The emission and absorption probabilities of the spin-3/2 particles on these spacetimes are calculated. These backgrounds which we analyze contain both black hole horizon and acceleration horizon, and have general electric and magnetic charges, rotation, and acceleration parameter. The properties of the spin-3/2 field near the acceleration horizon are also computed.

Использование в качестве сидератов смешанных агросообществ при правильном подборе компонентов в эти смеси может быть эффективным средством повышения потенциального и эффективного плодородия пахотных черноземов, улучшения их агрохимических и агрофизических свойств.As a result of replacing traditional dump plowing with less expensive methods of basic processing of arable soils, agroevolution and insufficient fertilizer intake, the degradation of agrophysical and agrochemical properties of soil resources often occurs, accompanied by a deterioration in the density of addition, pore and structural condition of the soil, a decrease in the content of organic matter and plant nutrition elements, as well as other negative phenomena in the arable soils. Using mixed agricultural communities as siderates with the correct selection of components in these mixtures can be an effective means of increasing the potential and effective fertility of arable chernozems, improving their agrochemical and agrophysical properties.

description: Helium atoms in Rydberg states have been manipulated coherently with microwave radiation pulses near a gold surface and near a superconducting NbTiN surface at a temperature of $3 \text{K}$. The experiments were carried out with a skimmed supersonic beam of metastable $(1\text{s})^1(2\text{s})^1\, {}^1\text{S}_0$ helium atoms excited with laser radiation to $n\text{p}$ Rydberg levels with principal quantum number $n$ between $30$ and $40$. The separation between the cold surface and the center of the collimated beam is adjustable down to $250 μ\text{m}$. Short-lived $n\text{p}$ Rydberg levels were coherently transferred to the long-lived $n\text{s}$ state to avoid radiative decay of the Rydberg atoms between the photoexcitation region and the region above the cold surfaces. Further coherent manipulation of the $n\text{s}$ Rydberg levels with pulsed microwave radiation above the surfaces enabled measurements of stray electric fields and allowed us to study the decoherence of the atomic ensemble. Adsorption of residual gas onto the surfaces and the resulting slow build-up of stray fields was minimized by controlling the temperature of the surface and monitoring the partial pressures of H$_2$O, N$_2$, O$_2$ and CO$_2$ in the experimental chamber during the cool-down. Compensation of the stray electric fields to levels below $100 \text{mV}/\text{cm}$ was achieved over a region of $6 \text{mm}$ along the beam-propagation direction which, for the $1770 \text{m}/\text{s}$ beam velocity, implies the possibility to preserve the coherence of the atomic sample for several microseconds above the cold surfaces.

description: Objectives: This thesis aimed at: 1) examining factors related to school participation attendance and involvement among children and youth with craniofacial microsomia (CFM) and other childhood-onset disabilities; 2) identifying the current scope of participation-focused interventions using artificial intelligence (AI) in pediatric re/habilitation and to examine how participation is currently operationalized in this area of work; and 3) developing a predictive model using natural language processing that classifies participation-focused caregiver strategies to four key predictors of participation . Methods: Aim 1 applied structural equation modeling using secondary analyses of a subset of data including 260 families of children and youth with CFM and other childhood-onset disabilities. Aim 2 included two scoping reviews, which together mapped research according to the type(s) of AI and extent of customization used in participation-focused pediatric re/habilitation interventions and ways of operationalizing participation in pediatric re/habilitation research using AI. Aim 3 employed narrative data on 1,576 participation-focused strategies from 236 families of the Aim 1 dataset. A series of binary and multinomial logistic regression, naïve Bayes, and support vector machines (SVM) models were developed and compared. Results: For Aim 1, results revealed a significant positive association between school environmental supports and school participation attendance and involvement, a significant negative association between physical functioning problems and school participation involvement and a significant effect of the number of participation-focused caregiver strategies on the relationship between school environmental support and school participation attendance. For Aim 2, most AI-based participation-focused pediatric re/habilitation interventions used robotics and were not customized to individually reported needs of children and youth with childhood-onset disabilities. Operationalizations of participation in AI-based participation-focused pediatric rehabilitation research were not aligned with contemporary definitions of child and youth participation. For Aim 3, SVM models revealed accuracy scores from 78.10% - 94.92% and macro-averaged F1-scores from 0.58 – 0.83. Conclusion: Results yield evidence of the use of AI to customize the use of information about participation-focused caregiver strategies when delivering pediatric re/habilitation services for a diversified group of children and youth with childhood-onset disabilities.

description: (Abridged) Aims. We intend to derive statistical properties of stochastic gas motion inside the dense low mass star forming molecular cores traced by NH3(1,1) and (2,2) emission lines. Methods. We use the spatial two-point autocorrelation (ACF) and structure functions calculated from maps of the radial velocity fields. Results. We find oscillating ACFs which eventually decay to zero with increasing lags on scales of 0.04 <= l <= 0.5 pc. The current paradigm supposes that the star formation process is controlled by the interplay between gravitation and turbulence, the latter preventing molecular cores from a rapid collapse due to their own gravity. Thus, oscillating ACFs may indicate a damping of the developed turbulent flows surrounding the dense but less turbulent core - a transition to dominating gravitational forces and, hence, to gravitational collapse.

description: Vanadium sesquioxide, V2O3, is a prototypical metal-to-insulator system where, in temperature-dependent studies, the transition always coincides with a corundum-to-monoclinic structural transition. As a function of pressure, V2O3 follows the expected behavior of increased metallicity due to a larger bandwidth for pressures up to 12.5 GPa. Surprisingly, for higher pressures when the structure becomes unstable, the resistance starts to increase. Around 32.5 GPa at 300 K, we observe a novel pressure-induced corundum-to-monoclinic transition between two metallic phases, showing that the structural phase transition can be decoupled from the metal-insulator transition. Using X-ray Raman scattering, we find that screening effects, which are strong in the corundum phase, become weakened at high pressures. Theoretical calculations indicate that this can be related to a decrease in coherent quasiparticle strength, suggesting that the high-pressure phase is likely a critical correlated metal, on the verge of Mott-insulating behavior.

description: Malicious actors may seek to use different voice-spoofing attacks to fool ASV systems and even use them for spreading misinformation. Various countermeasures have been proposed to detect these spoofing attacks. Due to the extensive work done on spoofing detection in automated speaker verification (ASV) systems in the last 6-7 years, there is a need to classify the research and perform qualitative and quantitative comparisons on state-of-the-art countermeasures. Additionally, no existing survey paper has reviewed integrated solutions to voice spoofing evaluation and speaker verification, adversarial/antiforensics attacks on spoofing countermeasures, and ASV itself, or unified solutions to detect multiple attacks using a single model. Further, no work has been done to provide an apples-to-apples comparison of published countermeasures in order to assess their generalizability by evaluating them across corpora. In this work, we conduct a review of the literature on spoofing detection using hand-crafted features, deep learning, end-to-end, and universal spoofing countermeasure solutions to detect speech synthesis (SS), voice conversion (VC), and replay attacks. Additionally, we also review integrated solutions to voice spoofing evaluation and speaker verification, adversarial and anti-forensics attacks on voice countermeasures, and ASV. The limitations and challenges of the existing spoofing countermeasures are also presented. We report the performance of these countermeasures on several datasets and evaluate them across corpora. For the experiments, we employ the ASVspoof2019 and VSDC datasets along with GMM, SVM, CNN, and CNN-GRU classifiers.

description: Mood is a central concept when dealing with an individual’s mental state, since mood changes reflect changes in the mental process. The most used method to assess the mental heath status of a patient is represented by self-report questionnaires, but their main issue is their instantaneous and intermittent nature, that is therefore not able to capture intraindividual variability, which indeed represents a further significant clinical information. In order to obtain a better and more accurate assessment of the patient’s mental health status, it is therefore paramount to acquire data that are as granular as possible and collected, not in a controlled environment, but during the patient’s daily life. In that regard smartphone, with their widespread and ubiquitous adoption, could be exploited to combine passive sensing to evaluate mental health and active querying through Eco- logical Momentary Assessments (EMAs). Thus, the aim of this study is to integrate data collected through the use of self-report questionnaires, to data relative to the smartphone’s keyboard dynamic, collected passively by the BiAffect application, and use these data to better understand and stratify mood instability. In order to do so we proposed a novel approach based on the use of Personas. This is a new emerging method in the healthcare, clinical health IT or consumer health IT sectors, which consists in creating a generic participant, called Persona, inside a cluster of users that share similar aspects and embody the same archetype of user. It is oriented toward achieving personalized digital healthcare solutions. The study has been conducted over a small sample of 6 females with a diagnosis of mood instability. Every day we extracted 14 features from the BiAffect’s application and 72 self- report questionnaires variables, composed of some already validated questionnaires along with some other questions regarding medication adherence, stressor exposure, medication, drug and alcohol use, sleep, pain, illness, and exercise. After having preprocessed both the self-report questionnaires and the BiAffect data, we merged the two datasets together in order to create a unique input dataset. For the creation of Personas, we have decided to use the code ”PersonaCreator” generated by Emanuele Tauro from Polytechnic of Milan. The two Personas created have 68 out of 86 variables significantly (pvalue < 0.001) different between the two clusters. To provide an output that would have been much more user-friendly, we constructed a person card for each cluster. Lastly, we validated the Personas developed. The results have shown a great capability to distinguish between the clusters, suggesting that the clustering was well performed and the obtained Personas are valid and usable. Given the goodness and validity of the obtained results, we can say that with our work we have paved the way for the use of Personas on BiAffect data to stratify mood instability.

description: В статье рассматривается ситуация, которая складывается на современном этапе развития Российской Федерации в одной из важнейших категорий земельземли сельскохозяйственного назначения. Хотя государство нацелено на обеспечение продовольственной безопасности населения для чего отмечает необходимым повышать плодородие земель, недопущение сокращения площади земель сельскохозяйственного назначения, но согласно данным статистической отчетности количество земель сельскохозяйственного назначения с каждым годом уменьшаются за счет перевода земель сельскохозяйственного назначения в другие категории. На примере статистических данных Республики Алтай рассматриваются основные причины перевода земель сельскохозяйственного назначения в условиях дефицита сельскохозяйственных угодий, а также авторами предлагаются меры для защиты земель сельскохозяйственного назначения от перевода в другие категории.The article considers the situation that is developing at the present stage of development of the Russian Federation in one of the most important categories of land agricultural land. Although the state is aimed at ensuring food security of the population, for which it is necessary to increase the fertility of land and prevent the reduction of the area of agricultural land, but according to statistical reports, the number of agricultural land is decreasing every year due to the transfer of agricultural land to other categories. Using the example of statistical data from the Republic of Altai, the authors consider the main reasons for the transfer of agricultural land in conditions of shortage of agricultural land, and also propose measures to protect agricultural land from transfer to other categories.
