description: The aim of the study was to evaluate the usefulness of the municipality’s development strategy as a tool for managing the development of natural valuable areas of the Lublin province. The objective was served by the analysis of literature, development strategy documents and the results of research carried out in 30 municipalities in the group with the highest environmental values in the Lublin province, according to the indicator developed by Danuta Guzal-Dec in the study of natural values of rural and urban-rural municipalities of the Lublin province – the procedure is described in detail in [Guzal-Dec 2013]. Fieldwork was carried out in the fourth quarter of 2013 using an interview questionnaire addressed to mayors. It was found that, despite the general eligibility of the documents analyzed, incorrectness in their preparation and implementation were identified which determine the low efficiency of these strategies as tools for managing the development and creation of sustainable development. The study allowed us to confirm the hypothesis that local development strategies are underexploited management tools for development of communes located in valuable natural areas of the Lublin province.

description: Many current behavior generation methods struggle to handle real-world traffic situations as they do not scale well with complexity. However, behaviors can be learned off-line using data-driven approaches. Especially, reinforcement learning is promising as it implicitly learns how to behave utilizing collected experiences. In this work, we combine policy-based reinforcement learning with local optimization to foster and synthesize the best of the two methodologies. The policy-based reinforcement learning algorithm provides an initial solution and guiding reference for the post-optimization. Therefore, the optimizer only has to compute a single homotopy class, e.g.\ drive behind or in front of the other vehicle. By storing the state-history during reinforcement learning, it can be used for constraint checking and the optimizer can account for interactions. The post-optimization additionally acts as a safety-layer and the novel method, thus, can be applied in safety-critical applications. We evaluate the proposed method using lane-change scenarios with a varying number of vehicles.
Weak ferromagnetism in antiferromagnets: Fe$_{2}$O$_{3}$ and La$_{2}$CuO$_{4}$

description: The problem of weak ferromagnetism in antiferromagnets due to canting of magnetic moments was treated using Green's function technique. At first the eigenvalues and eigenfunctions of the electronic Hamiltonian corresponding to collinear magnetic configuration are calculated which are then used to determine first and second variations of the total energy as a function of the magnetic moments canting angle. Spin-orbit coupling is taken into account via perturbation theory. The results of calculations are used to determine an effective spin Hamiltonian. This Hamiltonian can be mapped on conventional spin Hamiltonian that allows to determine parameters of isotropic and anisotropic (Dzyaloshinskii-Moriya) exchange interactions. The method was applied to the typical antiferromagnets with weak ferromagnetism Fe$_{2}$O$_{3}$ and La$_{2}$CuO$_{4}$. The obtained directions and values of the magnetic moments canting angles are in a reasonable agreement with experimental data.

Statistical properties of exoplanets IV. The period--eccentricity relations of exoplanets and of binary stars

description: A sample of spectroscopic binaries and a sample of single planetary systems, both having main-sequence solar-type primary components, are selected in order to compare their eccentricities. The positions of the objects in the (P.(1-e^2)^(3/2), e) plane is used to determine parts in the period-eccentricity diagram that are not affected by tidal circularization. The original eccentricities of binaries and planets are derived and compared. They seem to be weakly or not at all correlated with period in both samples, but two major differences are found :(1) The tidal circularization of planetary orbits is almost complete for periods shorter than 5 days, but it is not visible when P.(1-e^2)^{3/2} is longer than this limit. This suggests that the circularization occurs rapidly after the end of the migration process and is probably simultaneous with the end of the formation of the planet. By contrast, we confirm that the circularization of the binary orbits is a process still progressing a long time after the formation of the systems.(2) Beyond the circularization limit, the eccentricities of the orbits of the planets are significantly smaller than those of binary orbits, and this discrepancy cannot be due to a selection effect. Moreover, the eccentricities of binaries with small mass ratios are quite similar to those of all binaries with q<0.8. This suggests that the low eccentricities of exoplanet orbits are not a consequence of low-mass secondaries in a universal process. These remarks are in favor of the idea that binaries and exoplanets are two different classes of object from the point of view of their formation.

description: We study the transport properties of underdoped trilayer cuprate HgBa$_2$Ca$_2$Cu$_3$O$_{8+ δ}$ with doping level $p$ = 0.1 - 0.12 in magnetic field up to 88 T. We report for the first time in a cuprate superconductor a dramatic change of the quantum oscillation spectrum versus temperature, which is accompanied by a sign change of the Hall effect below $T \approx$ 10 K. Based on numerical simulations, we infer a Fermi surface reconstruction in the inner plane from an antiferromagnetic state (hole pockets) to a biaxial charge density wave state (electron pockets). We show that both orders compete and share the same hotspots of the Fermi surface and we discuss our result in the context of spin-fermion models.

description: Rapid progress in nonlinear plasmonic metasurfaces enabled many novel optical characteristics for metasurfaces, with potential applications in frequency metrology, timing characterization and quantum information. However, the spectrum of nonlinear optical response was typically based upon the linear optical resonance. In this work, a wavelength-multiplexed nonlinear plasmon-MoS2 hybrid metasurface with suppression phenomenon was proposed, where multiple nonlinear signals could to be simultaneously processed and optionally tuned. A clear physical picture to depict the nonlinear plasmonic bound states in the continuum (BICs) was presented, from the perspective of both classical and quantum approaches. Particularly, beyond the ordinary plasmon-polariton effect, we numerically demonstrated a giant BIC-inspired second-order nonlinear susceptibility $10^{-5}$~$m/V$ of MoS2 in the infrared band. The novelty in our study lies in the presence of a quantum oscillator that can be adopted to both suppress and enhance the nonlinear quasi BICs. This selectable nonlinear BIC-based suppression and enhancement effect can optionally block undesired modes, resulting in narrower linewidth as well as smaller quantum decay rates, which is also promising in slow-light-associated technologies.

description: Access to actionable data on fresh food supply chains bring key advantages for various stakeholders from the public and private sectors for better decision-making. For India, many agriculture-related data are publicly available as open-source data. However, many available data are not easy to access or visualize and may require a certain degree of processing before they can be turned into interpretable information for decision-making. For that reason, these data are often not used to their full potential. Here we present an interactive web map[1] that collates and visualizes relevant open-source data for fresh food supply chains in India. The available data layers include cropland, elevation, electrical grid, crop production, cold storage locations, air temperature, solar radiation, road network, market locations, mobile coverage, and census. This visual representation of the selected data layers serves as a decision-making tool for stakeholders in the fresh produce supply chain, including social enterprises like farmer producer organizations and policymakers, as well as financial institutions, cooling providers, NGOs, and government bodies. A practical example of this is identifying where cooling could provide the highest shelf life gains and where to site future cold storage facilities. We anticipate that this web map can lead to finding relevant insights that could help stakeholders optimize their supply chain of fresh produce. This web map could be a starting point for understanding correlations between various parameters and for narrowing the data literacy gap in agricultural sectors in India.

description: The Ayy data for deuteron inclusive breakup off hydrogen and carbon at a deuteron momentum of 9.0 GeV/c and large Pt of emitted protons are presented. The large values of Ayy independent of the target mass reflect the sensitivity of the data to the deuteron spin structure. The data obtained at fixed $x$ and plotted versus Pt clearly demonstrate the dependence of the deuteron spin structure at short internucleonic distances on two variables. The data are compared with the calculations using Paris, CD-Bonn and Karmanov's deuteron wave functions.

description: The optical spectra of two dimensional (2D) materials exhibit sharp absorption peaks that are commonly identified with exciton and trions (or charged excitons). In this paper, we show that excitons and trions in doped 2D materials can be described by two coupled Schrodinger-like equations - one two-body equation for excitons and another four-body equation for trions. In electron doped 2D materials, a bound trion state is identified with a four-body bound state of an exciton and an excited conduction band electron-hole pair. In doped 2D materials, the exciton and the trions states are the not the eigenstates of the full Hamiltonian and their respective Schrodinger equations are coupled due to Coulomb interactions. The strength of this coupling increases with the doping density. Solutions of these two coupled equations can quantitatively explain all the prominent features experimentally observed in the optical absorption spectra of 2D materials including the observation of two prominent absorption peaks and the variation of their energy splittings and spectral shapes and strengths with the electron density. The optical conductivity obtained in our work satisfies the optical conductivity sum rule exactly. A superposition of exciton and trion states can be used to construct a solution of the two coupled Schrodinger equations and this solution resembles the variational exciton-polaron state, thereby establishing the relationship between our approach and Fermi polaron physics.

description: The sale prices of Baltic sea fish, often referred to first sale prices obtained by fisherman at ports, similarly to the prices of other food products are shaped by many factors. Mutual linkages of the factors and direction of their impact on the level of prices are very difficult to estimate. To recognise at least rough patterns and future changes on a given market is of great importance in the decision-making process in the future. The paper addresses an analysis of the patterns of changes in the prices of basic fish species over the past 11 years.

description: Recourse is introduced to the binomial collateral equilibrium model described by Geanakoplos and Fostl in their Econometrica paper "Leverage and default in binomial economies: A complete characterization". First, the paper's main results, culminating in the binomial no-default theorem, are examined in this generalized setting. This theorem ensures that any collateral equilibrium can be translated to a default-free equilibrium with the same prices and identical allocations of goods, yet different debt contract and asset allocations. It is shown that the theorem is valid in specific circumstances only. Then, welfare considerations are introduced. Examples motivate the conjecture that in an equilibrium in which the collateral is scarce and borrowing is maximal, every investor's utility can be improved upon by increasing the recovery rate. Even though, closed-form expressions for marginal utility changes are derived, attempts to prove that they are positive were not successful yet.

The highest consumption of fresh vegetables appeared in households of retirees and pensioners, farmers, marriages without children and households with the highest income. A high consumption of vegetables preserves was observed among pensioners, self-employed and employees in non-manual labour positions. The consumption of vegetable preserves decreased with increasing numbers of children in the family, and increased with the amount of income. In the analyzed period in all groups of households consumption of fresh vegetables decreased and the consumption of vegetable preserves increased, and the range of these changes depended on the type of household.

description: Sampling autonomy for icy moon lander missions requires understanding of topographic and photometric properties of the sampling terrain. Unavailability of high resolution visual datasets (either bird-eye view or point-of-view from a lander) is an obstacle for selection, verification or development of perception systems. We attempt to alleviate this problem by: 1) proposing Graphical Utility for Icy moon Surface Simulations (GUISS) framework, for versatile stereo dataset generation that spans the spectrum of bulk photometric properties, and 2) focusing on a stereo-based visual perception system and evaluating both traditional and deep learning-based algorithms for depth estimation from stereo matching. The surface reflectance properties of icy moon terrains (Enceladus and Europa) are inferred from multispectral datasets of previous missions. With procedural terrain generation and physically valid illumination sources, our framework can fit a wide range of hypotheses with respect to visual representations of icy moon terrains. This is followed by a study over the performance of stereo matching algorithms under different visual hypotheses. Finally, we emphasize the standing challenges to be addressed for simulating perception data assets for icy moons such as Enceladus and Europa.

description: A systematic study of isospin effects in the breakup of projectile spectators at relativistic energies has been performed with the ALADiN spectrometer at the GSI laboratory (Darmstadt). Four different projectiles 197Au, 124La, 124Sn and 107Sn, all with an incident energy of 600 AMeV, have been used, thus allowing a study of various combinations of masses and N/Z ratios in the entrance channel. The measurement of the momentum vector and of the charge of all projectile fragments with Z>1 entering the acceptance of the ALADiN magnet has been performed with the high efficiency and resolution achieved with the TP-MUSIC IV detector. The Rise and Fall behavior of the mean multiplicity of IMFs as a function of Zbound and its dependence on the isotopic composition has been determined for the studied systems. Other observables investigated so far include mean N/Z values of the emitted light fragments and neutron multiplicities. Qualitative agreement has been obtained between the observed gross properties and the predictions of the Statistical Multifragmentation Model.

Investigating Gravitational Collapse of a Pebble Cloud to form Transneptunian Binaries

description: Context. A large fraction of transneptunian objects are found in binary pairs, ~30% in the cold classical population between $a_\text{hel}$~39 and ~48 AU. Observationally, these binaries generally have components of similar size and colour. Previous work has shown that gravitational collapse of a pebble cloud is an efficient mechanism for producing such systems. Since the discovery of the bi-lobate nature of Arrokoth there is also interest in gravitational collapse as a way to form contact binaries. Aims. Our aim was to investigate formation of binary systems via gravitational collapse, considering a wider range of binary masses than previous studies. We analysed in detail the properties of the bound systems that are formed and compared them to observations. Methods. We performed N-body simulations of gravitational collapse of a pebble cloud using the REBOUND package, with an integrator designed for rotating reference frames and robust collision detection. We conducted a deep search for gravitationally bound particles at the end of the gravitational collapse phase and tested their stability. For all systems produced, not just the most massive binaries, we investigated the population characteristics of their mass and orbital parameters. Gravitational collapse can create binary systems analogous to Arrokoth and collisions in a collapsing cloud should be gentle enough to preserve a bi-lobed structure. Results. Gravitational collapse is an efficient producer of bound planetesimal systems. On average ~1.5 bound systems were produced per cloud in the mass range studied here. As well as the large equal-sized binaries, we found that gravitational collapse produces massive bodies with small satellites and low mass binaries with a high mass ratio. Our results disfavour the collapse of high mass clouds, in line with reported upper mass limits of clouds formed by the streaming instability.

description: We present an analysis, based on the center-edge asymmetry, to distinguish effects of extra dimensions within the Arkani-Hamed-Dimopoulos-Dvali (ADD) and Randall-Sundrum (RS) scenarios from other new physics effects in lepton-pair production at the CERN Large Hadron Collider LHC. Spin-2 and spin-1 exchange can be distinguished up to an ADD cutoff scale, M_H, of about 5 TeV, at the 95% CL. In the RS scenario, spin-2 resonances can be identified in most of the favored parameter space.

description: We prove that every complete, minimally immersed submanifold $f\: M^n \to \mathbb{S}^{n+p}$ whose second fundamental form satisfies $|A|^2 \le np/(2p-1)$, is either totally geodesic, or (a covering of) a Clifford torus or a Veronese surface in $\mathbb{S}^4$, thereby extending the well-known results by Simons, Lawson and Chern, do Carmo & Kobayashi from compact to complete $M^n$. We also obtain the corresponding result for complete hypersurfaces with nonvanishing constant mean curvature, due to Alencar & do Carmo in the compact case, under the optimal bound on the umbilicity tensor. In dimension $n \le 6$, a pinching theorem for complete higher-codimensional submanifolds with non-vanishing parallel mean curvature is proved, partly generalizing previous work of Santos. Our approach is inspired by the conformal method of Fischer-Colbrie, Shen & Ye and Catino, Mastrolia & Roncoroni.

description: Agricultural land is mostly used for food production, but often it is treated as a land resource which can be used in any way. Modifications and changes in this sensitive system results in irreversible losses of production space. Particularly valuable soil complexes are protected by law. The aim of the analysis is to present the legal norms operating in Poland, Russia and Ukraine, related to the protection of agricultural lands and to their use. The analysis of legislation presents the procedures and conditions that must be met during the change of use of agricultural land. In each of the analyzed countries much attention is paid to rational use of agricultural land, but they do not always have prohibitions changing their usage. Comparing statistics from 2008 and 2013 it can be seen that the most unfavorable changes in the agricultural space took place in Poland, where the amount of arable land decreased by 3.7 million acres. / Synopsis. Grunty rolne głównie służą do produkcji żywności, jednak często są one traktowane jako rezerwuar obszarów, które mogą zostać wykorzystane w dowolny sposób. Przekształcenie i wprowadzenie zmian w tym wrażliwym systemie skutkuje nieodwracalną utratą przestrzeni produkcyjnej. Szczególnie cenne kompleksy glebowe są chronione prawem. Celem analizy jest przedstawienie norm prawnych funkcjonujących w Polsce, Rosji i na Ukrainie, związanych z ochroną gruntów rolnych oraz z ich wykorzystaniem. Przeprowadzona analiza aktów prawnych pokazuje procedury i warunki jakie muszą zostać spełnione podczas zmiany sposobu użytkowania gruntów rolnych. Każde z analizowanych państw dużą uwagę poświęca racjonalnemu wykorzystaniu użytków rolnych, jednak nie wprowadza się tam zakazów zmiany ich sposobu użytkowania. Porównując dane statystyczne z roku 2008 i 2013 można zauważyć, że najbardziej niekorzystne zmiany w przestrzeni rolniczej zaszły w Polsce, gdzie ilość użytków rolnych zmniejszyła się o 1,5 mln ha.
Space-point calibration of the ALICE TPC with track residuals

description: In the upcoming LHC Run 3, starting in 2021, the upgraded Time Projection Chamber (TPC) of the ALICE experiment will record minimum bias Pb-Pb collisions in a continuous readout mode at an interaction rate up to 50 kHz. This corresponds to typically 4-5 overlapping collisions during the electron drift time in the detector. Despite careful tuning of the new quadruple GEM-based readout chambers, which fulfill the design requirement of an ion backflow below 1%, these conditions will lead to space-charge distortions of several centimeters that fluctuate in time. They will be corrected via a calibration procedure that uses the information of the Inner Tracking System (ITS), which is located inside, and the Transition Radiation Detector (TRD) and Time-Of-Flight system (TOF), located around the TPC, respectively. By using such a procedure the intrinsic track resolution of the TPC of a few hundred micrometers can be restored. The required online tracking algorithm for the TRD, which is based on a Kalman filter, is presented. The procedure matches extrapolated ITS-TPC tracks to TRD space-points utilizing GPUs. Subsequently these global tracks are refitted neglecting the TPC information. The residuals of the TPC clusters to the interpolation of the refitted tracks are used to create a map of space-charge distortions. Regular updates of the map compensate for changes in the TPC conditions. The map is applied in the final reconstruction of the data. First performance results of the tracking algorithm will be shown.

description: The theory of quaternionic slice regular functions was introduced in 2006 and successfully developed for about a decade over symmetric slice domains, which appeared to be the natural setting for their study. Some recent articles paved the way for a further development of the theory: namely, the study of slice regular functions on slice domains that are not necessarily symmetric. The present work is a panorama of geometric function theory in this new context, where new phenomena appear. For instance, the nature of the zero sets can be drastically different than in the symmetric case. The work includes differential, algebraic, topological properties, as well as integral and series representations, of slice regular functions over slice domains.

Critical lengths of Steklov eigenvalues of hypersurfaces of revolution in Euclidean space

description: We study the Steklov problem on hypersurfaces of revolution with two boundary components in Euclidean space. In a recent article, the phenomenon of critical length, at which a Steklov eigenvalue is maximized, was exhibited and multiple questions were raised. In this article, we conjecture that, in any dimension, there is a finite number of infinite critical length. To investigate this, we develop an algorithm to efficiently perform numerical experiments, providing support to our conjecture. Furthermore, we prove the conjecture in dimension $n = 3$ and $n = 4$.

description: Let p be a prime and F a field containing a primitive pth root of unity. Let E/F be a cyclic extension of degree p and G_E < G_F the associated absolute Galois groups. We determine precise conditions for the cohomology group H^n(E)=H^n(G_E,Fp) to be free or trivial as an Fp[Gal(E/F)]-module. We examine when these properties for H^n(E) are inherited by H^k(E), k>n, and, by analogy with cohomological dimension, we introduce notions of cohomological freeness and cohomological triviality. We give examples of H^n(E) free or trivial for each n in N with prescribed cohomological dimension.

description: We present an integrated magneto-photonic device for all-optical switching of non-volatile multi-bit spintronic memory. The bits are based on stand-alone magneto-tunnel junctions which are perpendicularly magnetized with all-optically switchable free layers, coupled onto photonic crystal nanobeam cavities on an indium phosphide based platform. This device enables switching of the magnetization state of the bits by locally increasing the power absorption of light at resonance with the cavity. We design an add/drop network of cavities to grant random access to multiple bits via a wavelength-division multiplexing scheme. Based on a three-dimensional finite-difference time-domain method, we numerically illustrate a compact device capable of switching and accessing 8 bits in different cavities with a 5 nm wavelength spacing in the conventional (C) telecommunication band. Our multi-bit device holds promise as a new paradigm for developing an ultrafast photonically-addressable spintronic memory and may also empower novel opportunities for photonically-driven spintronic-based neuromorphic computing.

description: Land – the basic factor of production in agriculture - has a strategic role for the country. Currently in Poland, the way of managing it depends mainly on private owners. The state acts only as a regulator. The aim of the article was to examine the propensity of farmers to change the area of their farms and to determine the most important, according to them, reasons for these changes, or lack thereof. The authors’ own surveys, conducted in Dolnośląskie Voivodship, have revealed that the tendency to change the area of farms is small, because the largest group of respondents were farmers who in the years 1999-2012 did not change it. The most important causes of this stagnation, included the perception that there was no need to change, because the area of their farms is sufficient for agricultural activities, and they receive area payments and benefits from the Agricultural Social Insurance Fund. / Synopsis. Ziemia – w rolnictwie podstawowy czynnik produkcji – dla kraju ma znaczenie strategiczne. Obecnie w Polsce głównie właściciele prywatni decydują o sposobie gospodarowania nią. Państwo pełni jedynie rolę regulatora. Celem artykułu było zbadanie skłonności rolników do zmian powierzchni swoich gospodarstw i ustalenie najważniejszych według nich przyczyn tych zmian lub ich braku. Badanie ankietowe przeprowadzone na terenie woj. dolnośląskiego pozwoliło stwierdzić, że skłonność do zmian powierzchni gospodarstw jest niewielka, bo najliczniejszą grupę badanych stanowili rolnicy, którzy w latach 1999-2012 nie zmienili jej. Do najważniejszych przyczyn tej stagnacji zaliczyli oni brak potrzeby zmian, bo powierzchnia ich gospodarstw jest wystarczająca do prowadzenia działalności rolniczej, otrzymywania dopłat obszarowych i świadczeń z KRUS.

description: The detection of gravitational waves emitted during a neutron star - black hole merger and the associated electromagnetic counterpart will provide a wealth of information about stellar evolution nuclear matter, and General Relativity. While the theoretical framework about neutron star - black hole binaries formed in isolation is well established, the picture is loosely constrained for those forming via dynamical interactions. Here, we use N-body simulations to show that mergers forming in globular and nuclear clusters could display distinctive marks compared to isolated mergers, namely larger masses, heavier black holes, and the tendency to have no associated electromagnetic counterpart. These features could represent a useful tool to interpreting forthcoming observations. In the Local Universe, gravitational waves emitted from dynamical mergers could be unravelled by detectors sensitive in the decihertz frequency band, while those occurring at the distance range of Andromeda and the Virgo Cluster could be accessible to lower-frequency detectors like LISA.
