description: We study the charmonium $p \bar{p} \to ψ(3770) π^0$ reaction using effective lagrangian approach where the contributions from well established $N^*$ states are considered, and all parameters are fixed in the process of $e^+e^- \to p \bar{p}π^0$ at center of mass energy $\sqrt{s} = 3.773$ GeV. The experimental data on the line shape of the mass distribution of the $e^+e^- \to p\bar{p}π^0$ can be well reproduced. Based on the studying of $e^+e^- \to p \bar{p}π^0$, the total and differential cross sections of the $p \bar{p} \to ψ(3770) π^0$ reaction are predicted. At the same time we evaluated also the cross sections of the $p \bar{p} \to ψ(3686) π^0$ reaction. It is shown that the contribution of nucleon pole to this reaction is largest close to the reaction threshold. However, the interference between nucleon pole and the other nucleon resonance can still change the angle distributions significantly. Those theoretical results may be test by the future experiments at $\overline{\mbox{P}}$ANDA.

Death and jackpot: Why do individual investors hold overpriced stocks?

description: Campbell, Hilscher, and Szilagyi (2008) show that firms with a high probability of default have abnormally low average future returns. We show that firms which have a high potential for default (‘death’) also tend to have a relatively high probability of extremely large (‘jackpot’) payoffs. We develop a model to predict jackpot returns and find that stocks with high predicted probabilities for jackpot returns earn abnormally low average returns consistent with an investor preference for skewed, lottery-like payoffs. Stocks with high death or jackpot probabilities have relatively low institutional ownership and the jackpot effect we document is much stronger in stocks with high limits to arbitrage. Jackpot and death probabilities are significantly correlated across firms, but we find evidence that jackpot effects are not merely a reflection of default effects: firms with high default probability but low jackpot probability (those with low past return skewness and low market-to-book ratios and sales growth) do not exhibit low average returns and both effects remain significant in Fama-MacBeth regressions. Overall, we find evidence consistent with the hypothesis that individual investors hold ‘overpriced’ stocks due to a preference for skewness and that the low average returns of such stocks persist due to limits to arbitrage.

description: Iridium oxides with a honeycomb lattice have been identified as platforms for the much anticipated Kitaev topological spin liquid: the spin-orbit entangled states of Ir4+ in principle generate precisely the required type of anisotropic exchange. However, other magnetic couplings can drive the system away from the spin-liquid phase. With this in mind, here we disentangle the different magnetic interactions in Li2IrO3, a honeycomb iridate with two crystallographically inequivalent sets of adjacent Ir sites. Our ab initio many-body calculations show that, while both Heisenberg and Kitaev nearest-neighbour couplings are present, on one set of Ir–Ir bonds the former dominates, resulting in the formation of spin-triplet dimers. The triplet dimers frame a strongly frustrated triangular lattice and by exact cluster diagonalization we show that they remain protected in a wide region of the phase diagram.

Показано, что анализ изданий Общества позволяет утверждать, что они являются важными источниками для изучения истории аграрной мысли России, формирования многих отраслей сельского хозяйства, начало процесса сельскохозяйственного образования, опытного дела. В изданиях МОСХ отражена эволюция образования аграрной науки. Успешная деятельность МОСХ на протяжении 100 летней истории во многом связана с изданием журналов, которые являлись фактически единственным средством коммуникации между землевладельцами и другими членами Общества.The article contains information about publishing activities of the Moscow society of agriculture (MOSH) from 1821 to 1917. This year marks the 200th anniversary of its history. It is shown that the analysis of the Society’s publications allows us to state that these publications are important sources for studying the history of agriculture thought in Russia, the establishment of many branches of agriculture, the beginning of a process of agricultural education, agricultural experiment. MOSH’s publications reflect the evolution of the formation of agricultural science. The successful activity of MOSH over its centenary history is associated with the publication of journals which were actually the only means of communication between landowners and other members of the Society.

description: The periodic tiling conjecture asserts that any finite subset of a lattice $\mathbb{Z}^d$ which tiles that lattice by translations, in fact tiles periodically. In this work we disprove this conjecture for sufficiently large $d$, which also implies a disproof of the corresponding conjecture for Euclidean spaces $\mathbb{R}^d$. In fact, we also obtain a counterexample in a group of the form $\mathbb{Z}^2 \times G_0$ for some finite abelian $2$-group $G_0$. Our methods rely on encoding a "Sudoku puzzle" whose rows and other non-horizontal lines are constrained to lie in a certain class of "$2$-adically structured functions," in terms of certain functional equations that can be encoded in turn as a single tiling equation, and then demonstrating that solutions to this Sudoku puzzle exist, but are all non-periodic.

News-driven return reversals: Liquidity provision ahead of earnings announcements

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: This study documents a six-fold increase in short-term return reversals during earnings announcements relative to non-announcement periods. Following prior research, we use reversals as a proxy for expected returns market makers demand for providing liquidity. Our findings highlight significant time-series variation in the magnitude of short-term return reversals and suggest that market makers demand higher expected returns prior to earnings announcements because of increased inventory risks that stem from holding net positions through the release of anticipated earnings news. Collectively, our findings suggest that uncertainty regarding anticipated information events elicits predictable increases in the compensation demanded for providing liquidity and that these increases significantly affect the dynamics and information content of market prices.

description: Predicting the Credit Defaulter is a perilous task of Financial Industries like Banks. Ascertaining non-payer before giving loan is a significant and conflict-ridden task of the Banker. Classification techniques are the better choice for predictive analysis like finding the claimant, whether he/she is an unpretentious customer or a cheat. Defining the outstanding classifier is a risky assignment for any industrialist like a banker. This allow computer science researchers to drill down efficient research works through evaluating different classifiers and finding out the best classifier for such predictive problems. This research work investigates the productivity of LADTree Classifier and REPTree Classifier for the credit risk prediction and compares their fitness through various measures. German credit dataset has been taken and used to predict the credit risk with a help of open source machine learning tool.

description: How can a practicing teacher focus on student learning in a scholarly fashion? Over the last three decades, in several physics departments at American universities, Physics Education Research (PER) established itself alongside traditional fields such as Solid State or High Energy Physics. Promoted and advanced by discipline-scientists, PER critically evaluates the effectiveness of approaches to higher-education teaching and learning. What brought about this cultural change? The paper chronicles the slow but steady rise of a new field of inquiry and discusses opportunities and challenges for replicating the establishment of Discipline- Based Educational Research (DBER) at European universities.

description: Представлено обоснование земельной ренты как экономической патологии. Показано, что ее присвоение является тормозом общественного воспроизводства, так как, во-первых, выплата земельной ренты в любой форме приводит к росту издержек производителя продуктов земледелия и тем самым снижает их конкурентоспособность на агропродовольственных рынках; во-вторых, сельхозтоваропроизводители в целях экономии на обязательных платежах стремятся повышать интенсивность использования либо арендуемых, либо приобретенных земель, превращая ренту в фактор технологически избыточной интенсификации; в-третьих, земельная рента в некоторых случаях может являться фактором, тормозящим интенсификацию сельскохозяйственного производства; в-четвертых, рентные платежи, сокращая финансовые возможности многих сельхозтоваропроизводителей (особенно мелких), ограничивают спрос на землепользование; в-пятых, рентные отношения заметно усложняют вывод экономики из аграрных кризисов; в-шестых, рентные отношения способны мешать рациональному формированию фонда обрабатываемых земель за счет земель относительно лучшего качества; в-седьмых, рента, присвоенная частным земельным собственником, лишь частично и далеко не всегда используется на производственные цели.The paper presents theoretical underpinning of land rent as an economic pathology, as well as of the fact that rent seeking acts as a brake on social reproduction, since, firstly, land rental payment in any form raises the costs of the producer of agricultural products and consequently reduces their competitiveness in agri-food markets; secondly, for reasons of payments economy agricultural producers tend to increase land use intensity of either leased or purchased land, and, thus, turning rent into a factor of technologically excessive intensification; thirdly, land income in some cases becomes a brake on the intensification of agricultural production; fourthly, land rental payment limits the financial capabilities of many agricultural producers, especially small ones, and, as a result, limits the demand in land rental market; fifthly, rental relations significantly complicate agricultural crises bailout of the economy; sixthly, rental relations can repress rational formation of the fund of cultivated land due to the existence of lands of relatively better quality; seventhly, rent appropriated by the private land owner is only partially and is not always is used for production purposes.

description: We investigate the thermodynamics of a dark energy bulk viscosity model as a cosmic fluid. In this regard, the two theories of Eckart and Israel-Stewart (IS) are the basis of our work. Therefore, we first investigate the thermodynamics of cosmic fluids in the dark energy bulk viscosity model and the general relationships. Then, we express the thermodynamic relationships of Eckart's theory. Due to the basic equations of Eckart's theory and Friedmann's equations, we consider two states, one is $p=-ρ$ (standard) and the other is $p\neq-ρ$ (non-standard). In the standard state, we define the pressure $(p)$, energy density $(ρ)$, and bulk viscosity coefficient $(ξ)$ of the cosmic fluid in terms of cosmic time and we obtain its relations. We also mention that in this standard state, because of $p=-ρ$, the value of $a(t)$ is zero, so $a(t)$ is not defined in this state. But in the non-standard case $(p\neq-ρ)$ the bulk viscosity coefficient $(ξ)$ is zero and only the scale factor and pressure and energy density of the cosmic fluid is defined. We also consider two states of constant and variable bulk viscosity coefficients and obtain three Hubble constant parameters and scale factors in terms of cosmic time, and energy density in terms of the scale factor. In the state of variable bulk viscosity coefficient, we consider the viscosity coefficient as the power-law from energy density $(ξ=αρ^{s})$, which is $α>0$ and a constant. Following, we discuss the dissipative effects of cosmic fluids and examine the effects of energy density for dark energy in the Israel-Stewart(IS) theory. The results are comprehensively presented in two tables (1) and (2).

description: An air-mass modification, on its way from Poland to Romania, observed between 19-21 July 2014 is discussed. The air-mass was investigated using data of two multi-wavelength lidars capable of performing regular elastic, depolarization and Raman measurements in Warsaw, Poland, and in Magurele, Romania. The analysis was focused on evaluating optical properties of aerosol in order to search for similarities and differences in the vertical profiles describing the atmospheric layers above the two stations within given period.
Evaluation of different teaching interventions to motivate agricultural students in the lecture of animal health

name: Suter, Roman
Publisher: name: ETH Learning and Teaching Journal
Year: 2020

description: Student motivation is an important factor for successful learning. The aim of this study was to describe and evaluate specific teaching interventions used in teaching animal health to students of agronomy. For evaluating the motivation of students, the MUSIC® Model from Jones rated on a 6-point Likert type scale was used. By means of the MUSIC® inventory and open questions at the end of the semester, students were asked about their perception of different interventions during the course. The caring component of the lecturer was evaluated at highest (5.7), followed by success (5.1), interest (4.8), usefulness (4.6) and empowerment (4.5) of the topics in this class. Furthermore, usefulness and interest seem to be the main driver for motivation among students in this study. Therefore, interventions which activate these components such as field trips with exercises and group discussions, should be regularly used in teaching to improve the motivation of students.

Turbulence on a Fractal Fourier set

description: A novel investigation of the nature of intermittency in incompressible, homogeneous and isotropic turbulence is performed by a numerical study of the Navier-Stokes equations constrained on a fractal Fourier set. The robustness of the energy transfer and of the vortex stretching mechanisms is tested by changing the fractal dimension, D, from the original three dimensional case to a strongly decimated system with D=2.5, where only about $3\%$ of the Fourier modes interact. This is a unique methodology to probe the statistical properties of the turbulent energy cascade, without breaking any of the original symmetries of the equations. While the direct energy cascade persists, deviations from the Kolmogorov scaling are observed in the kinetic energy spectra. A model in terms of a correction with a linear dependency on the co-dimension of the fractal set, $E(k) \sim k^{-5/3 + 3-D}$, explains the results. At small scales, the intermittency of the vorticity field is observed to be quasi-singular as a function of the fractal mode reduction, leading to an almost Gaussian statistics already at $D \sim 2.98$. These effects must be connected to a genuine modification in the triad-to-triad nonlinear energy transfer mechanism.

These functors are intended to help in the study of the crossed-product functors that have been recently introduced in relation to the Baum-Connes conjecture. The most important coaction functors are the ones induced by large ideals of the Fourier-Stieltjes algebra. It is left as an open problem whether the "minimal exact and Morita compatible crossed-product functor" is induced by a large ideal.

description: Modern theories of quantum magnetism predict exotic multipolar states in weakly interacting strongly frustrated spin-1/2 Heisenberg chains with ferromagnetic nearest neighbor (NN) inchain exchange in high magnetic fields. Experimentally these states remained elusive so far. Here we report strong indications of a magnetic field-induced nematic liquid arising above a field of ~13 T in the edge-sharing chain cuprate LiSbCuO4 ≡ LiCuSbO4. This interpretation is based on the observation of a field induced spin-gap in the measurements of the 7Li NMR spin relaxation rate T1−1 as well as a contrasting field-dependent power-law behavior of T1−1 vs. T and is further supported by static magnetization and ESR data. An underlying theoretical microscopic approach favoring a nematic scenario is based essentially on the NN XYZ exchange anisotropy within a model for frustrated spin-1/2 chains and is investigated by the DMRG technique. The employed exchange parameters are justified qualitatively by electronic structure calculations for LiCuSbO4.

High-frequency quoting, trading, and the efficiency of prices

Year: 2015

description: We examine the relation between high frequency quotation and the behavior of stock prices between 2009 and 2011 for the full cross-section of securities in the U.S. On average, higher quotation activity is associated with price series that more closely resemble a random walk, and significantly lower cost of trading. We also explore market resiliency during periods of exceptionally high low-latency trading: large liquidity drawdowns in which, within the same millisecond, trading algorithms systematically sweep large volume across multiple trading venues. Although such large drawdowns incur trading costs, they do not appear to degrade the subsequent price formation process or increase the subsequent cost of trading. In an out-of-sample analysis, we investigate an exogenous technological change to the trading environment on the Tokyo Stock Exchange that dramatically reduces latency and allows co-location of servers. This shock also results in prices more closely resembling a random walk, and a sharp decline in the cost of trading.
Sampling the Probability Distribution of Type Ia Supernova Lightcurve Parameters in Cosmological Analysis

description: In order to obtain robust cosmological constraints from Type Ia supernova (SN Ia) data, we have applied Markov Chain Monte Carlo (MCMC) to SN Ia lightcurve fitting. We develop a method for sampling the resultant probability density distributions (pdf) of the SN Ia lightcuve parameters in the MCMC likelihood analysis to constrain cosmological parameters, and validate it using simulated data sets. Applying this method to the Joint Lightcurve Analysis (JLA) data set of SNe Ia, we find that sampling the SN Ia lightcurve parameter pdf's leads to cosmological parameters closer to that of a flat Universe with a cosmological constant, compared to the usual practice of using only the best fit values of the SN Ia lightcurve parameters. Our method will be useful in the use of SN Ia data for precision cosmology.

description: Wilsonian effective theories exploit hierarchies of scale to simplify the description of low-energy behaviour and play as central a role for gravity as for the rest of physics. They are useful both when hierarchies of scale are explicit in a gravitating system and more generally for understanding precisely what controls the size of quantum corrections in gravitational systems. But effective descriptions are also relevant for open systems (e.g. fluid mechanics as a long-distance description of statistical systems) for which the `integrating out' of unobserved low-energy degrees of freedom complicate a straightforward application of Wilsonian methods. Observations performed only on one side of an apparent horizon provide examples where open system descriptions also arise in gravitational physics. This chapter describes some early adaptations of Open Effective Theories (i.e. techniques for exploiting hierarchies of scale in open systems) in gravitational settings. Besides allowing the description of new types of phenomena (such as decoherence) these techniques also have an additional benefit: they sometimes can be used to resum perturbative expansions at late times and thereby to obtain controlled predictions in a regime where perturbative predictions otherwise generically fail.

Commonality in the time-variation of stock–stock and stock–bond return comovements

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: We jointly investigate time-varying comovements between stock returns across countries and between long-term government bond and stock returns within countries. Our focus is on how daily return comovements vary with stock uncertainty, as measured by the implied volatility (IV) from equity index options. We contribute with the following primary findings. Cross-country stock return comovements tend to be stronger (weaker) following high (low) IV days and on days with large (small) changes in IV. Consistent with earlier work, stock-bond return comovements tend to be substantially positive (negative) following low (high) IV days and on days with small (large) changes in IV. Further, a regime-switching analysis indicates a striking temporal commonality in the stock-stock and stock-bond comovement variations. Our findings bear on understanding the influence of time-varying uncertainty on price formation across asset classes, and on understanding the benefits of stock-bond and cross-country stock diversification.

description: Charge carrier concentrations in acceptor-doped proton-conducting perovskites are to a large extent determined by the hydration and oxidation of oxygen vacancies, which introduce protons and holes, respectively. First-principles modeling of these reactions involves calculation of formation energies of charged defects, which requires an accurate description of the band gap and the position of the band edges. Since density-functional theory (DFT) with local and semi-local exchange-correlation functionals (LDA and GGA) systematically fails to predict these quantities this can have serious implications on the modeling of defect reactions. In this study we investigate how the description of band gap and band edge positions affects the hydration and oxidation in acceptor-doped BaZrO$_3$. First-principles calculations are performed in combination with thermodynamic modeling in order to obtain equilibrium charge carrier concentrations at different temperatures and partial pressures. Three different methods have been considered: DFT with both semi-local (PBE) and hybrid (PBE0) exchange-correlation functionals, and many-body perturbation theory within the $G_0W_0$-approximation. All three methods yield similar results for the hydration reaction, which are consistent with experimental findings. For the oxidation reaction, on the other hand, there is a qualitative difference. PBE predicts the reaction to be exothermic while the two others predict an endothermic behavior. Results from thermodynamic modeling are compared with available experimental data, such as enthalpies, concentrations and conductivities, and only the results obtained with PBE0 and $G_0W_0$, with an endothermic oxidation behavior, give a satisfactory agreement with experiments.

description: We study the cosmological implications of an effective field theory model derived within a configuration of D7 brane stacks in the framework of type-IIB string theory. We consider a suitable geometric setup where the Kähler moduli fields are stabilized and the parametric space is constrained so that a de Sitter vacuum is ensured. In addition to the moduli fields we also take into account the usual Higgs and matter fields included in the effective field theory. In this background, we implement the standard hybrid inflation scenario with a singlet scalar field acting as the inflaton and the Higgs states serving as waterfall fields. Radiative corrections and soft supersymmetry breaking terms play an essential role in the realization of a successful inflationary scenario consistent with the present cosmological data. Small tensor-to-scalar ratio values are predicted, which can be probed in future planned experiments. Further constraints on the model's parameters are derived from bounds on dark radiation which is measured as a contribution to the effective number of neutrino species $N_{\rm eff}$. In particular, we find an excess of $ΔN_{\rm eff}\leq{0.95}$ at $2σ$ confidence level with natural values of the involved couplings.

Feedback and self-assessment in undergraduate student seminars in mathematics

Publisher: name: ETH Learning and Teaching Journal
Year: 2020

description: In this article we will discuss bachelor’s seminars in mathematics at ETH. Most students (in these seminars) are neither used to individually preparing material from textbooks nor to discussing advances mathematics with fellow students. As these seminars usually follow a single thread, it is often impossible to quickly catch up on the content of past lectures. Hence there is also the risk that students only focus on their own talks, which often results in badly aligned talks. To overcome these problems, we implemented two tweaks to the standard setup. These are extensive meetings with the organizers and few mandatory exercises. We will evaluate the success of these measures and, where success is scarce, propose further measures to possibly address these problems.

description: When spinning particles, such as electrons and photons, undergo spin–orbit coupling, they can acquire an extra phase in addition to the well-known dynamical phase. This extra phase is called the geometric phase (also known as the Berry phase), which plays an important role in a startling variety of physical contexts such as in photonics, condensed matter, high-energy and space physics. The geometric phase was originally discussed for a cyclically evolving physical system with an Abelian evolution, and was later generalized to non-cyclic and non-Abelian cases, which are the most interesting fundamental subjects in this area and indicate promising applications in various fields. Here, we enable optical spin–orbit coupling in asymmetric microcavities and experimentally observe a non-cyclic optical geometric phase acquired in a non-Abelian evolution. Our work is relevant to fundamental studies and implies promising applications by manipulating photons in on-chip quantum devices.
A Dual-Function Radar-Communication System Empowered by Beyond Diagonal Reconfigurable Intelligent Surface

description: This work focuses on the use of reconfigurable intelligent surface (RIS) in dual-function radar-communication (DFRC) systems to improve communication capacity and sensing precision, and enhance coverage for both functions. In contrast to most of the existing RIS aided DFRC works where the RIS is modeled as a diagonal phase shift matrix and can only reflect signals to half space, we propose a novel beyond diagonal RIS (BD-RIS) aided DFRC system. Specifically, the proposed BD-RIS supports the hybrid reflecting and transmitting mode, and is compatible with flexible architectures, enabling the system to realize full-space coverage and to achieve enhanced performance. To achieve the expected benefits, we jointly optimize the transmit waveform, the BD-RIS matrices, and sensing receive filters, by maximizing the minimum signal-to-clutter-plus-noise ratio for fair target detection, subject to the constraints of the communication quality of service, different BD-RIS architectures and power budget. To solve the non-convex and non-smooth max-min problem, a general solution based on the alternating direction method of multipliers is provided. Numerical simulations validate the efficacy of the proposed algorithm and show the superiority of the BD-RIS aided DFRC system in terms of both communication and sensing compared to conventional RIS aided DFRC.

Ambiguity Function of the Transmit Beamspace-Based MIMO Radar

description: In this paper, we derive an ambiguity function (AF) for the transmit beamspace (TB)-based multipleinput multiple-output (MIMO) radar for the case of far-field targets and narrow-band waveforms. The effects of transmit coherent processing gain and waveform diversity are incorporated into the AF definition. To cover all the phase information conveyed by different factors, we introduce the equivalent transmit phase centers. The newly defined AF serves as a generalized AF form for which the phased-array (PA) and traditional MIMO radar AFs are important special cases. We establish relationships among the defined TB-based MIMO radar AF and the existing AF results including the Woodward's AF, the AFs defined for the traditional colocated MIMO radar, and also the PA radar AF, respectively. Moreover, we compare the TB-based MIMO radar AF with the square-summation-form AF definition and identify two limiting cases to bound its 'clear region' in Doppler-delay domain that is free of sidelobes. Corresponding bounds for these two cases are derived, and it is shown that the bound for the worst case is inversely proportional to the number of transmitted waveforms K, whereas the bound for the best case is independent of K. The actual 'clear region' of the TB-based MIMO radar AF depends on the array configuration and is in between of the worst- and best-case bounds. We propose a TB design strategy to reduce the levels of the AF sidelobes, and show in simulations that proper design of the TB matrix leads to reduction of the relative sidelobe levels of the TB-based MIMO radar AF.

description: We analyse a numerical scheme for a system arising from a novel description of the standard elastic--perfectly plastic response. The elastic--perfectly plastic response is described via rate-type equations that do not make use of the standard elastic-plastic decomposition, and the model does not require the use of variational inequalities. Furthermore, the model naturally includes the evolution equation for temperature. We present a low order discretisation based on the finite element method. Under certain restrictions on the mesh we subsequently prove the existence of discrete solutions, and we discuss the stability properties of the numerical scheme. The analysis is supplemented with computational examples.

description: Процесс, связанный с совершенствованием законодательства в области земельного права, землеустройства, градостроительства, кадастра и государственной охраны объектов культурного наследия при организации и установлении правового режима использования земель, на которых расположены объекты недвижимости, имеющие историко-культурную ценность, охватывает целые десятилетия. При этом и современные условия организации и функционирования объектов культурного наследия характеризуются рядом противоречий между нормативно-правовыми требованиями по их сохранению и потребностями перспективного развития территорий для различного целевого их использования. Одной из причин этого выступает отсутствие единых и более четких понятий в действующей системе законодательства. В статье представлен анализ соответствия существующей практики организации данных территорий требованиям Российского законодательства, а также рекомендации по разрешению спорных вопросов. В качестве объекта исследования принята территория «Достопримечательное место «Нумто» Природного национального парка «Нумто» Белоярского муниципального района ХМАО.The article. For many decades, the Russian Federation has been in the process of improving legislation in the field of land law, land management, cadastre and state protection of cultural heritage objects while organizing and establishing the legal regime for the use of lands on which real estate objects of historical and cultural value are located. However, at present, there are still contradictions between the legal requirements for the preservation of cultural heritage and the needs for the development of territories for their various intended uses. One of the reasons is the lack of unified and clearer concepts in the current system of legislation. The article presents an analysis of the compliance of the existing practice of organizing these territories with the requirements of Russian legislation and recommendations for resolving disputes. As an object of study, the territory «Numto Landmark» of the «Numto» Natural National Park of the Beloyarsk municipal district of the Khanty-Mansi Autonomous Area was taken.
