description: We introduce a generative model to simulate radiation patterns within a jet using the Lund jet plane. We show that using an appropriate neural network architecture with a stochastic generation of images, it is possible to construct a generative model which retrieves the underlying two-dimensional distribution to within a few percent. We compare our model with several alternative state-of-the-art generative techniques. Finally, we show how a mapping can be created between different categories of jets, and use this method to retroactively change simulation settings or the underlying process on an existing sample. These results provide a framework for significantly reducing simulation times through fast inference of the neural network as well as for data augmentation of physical measurements.

description: Knowledge networks and social networks are the drivers of information sharing and they play an important role in diffusion of technology and related knowledge. In this study the key informants in a village setup are studies to understand the farmer’s network with an objective to understand the existing social, knowledge systems and their structure, characteristics and relationships between different actors. The purpose is to use these channels as means to disseminate technologies and related information. We use the network map analysis as a tool to demonstrate the linkages between the key actors. Attributes captured in the study are information flows between different actors, the type of information, timeliness and frequency of information and mode of communication. The study is undertaken in 6 districts covering 20 villages of Bihar where 111 key informants were interviewed and this is supplemented with survey of 1000 households. The paper uses a mixed approach of quantitative and qualitative analysis.

description: The Quantum Reverse Shannon Theorem has been a milestone in quantum information theory. It states that asymptotically reliable simulation of a quantum channel, assisted by unlimited shared entanglement, requires a rate of classical communication equal to the channel's entanglement-assisted classical capacity. In this paper, we study the error exponent of quantum channel simulation, which characterizes the optimal speed of exponential convergence of the performance towards the perfect, as the blocklength increases. Based on channel purified distance, we derive lower and upper bounds for the error exponent. Then we show that the two bounds coincide when the classical communication rate is below a critical value, and hence, we have determined the exact formula of the error exponent in the low-rate case. This enables us to obtain an operational interpretation to the channel's sandwiched Rényi information of order from 1 to 2, since our formula is expressed as a transform of this quantity. In the derivation, we have also obtained an achievability bound for quantum channel simulation in the finite-blocklength setting, which is of realistic significance.

Modeling the Formation of the Family of the Dwarf Planet Haumea

description: The dwarf planet (136108) Haumea has an intriguing combination of unique physical properties: near-breakup spin, two regular satellites, and an unexpectedly compact family. While these properties indicate formation by collision, there is no self-consistent and reasonably probable formation hypothesis that can connect the unusually rapid spin and the low relative velocities of Haumea family members ("Haumeans"). We explore and test the proposed formation hypotheses (catastrophic collision, graze-and-merge, and satellite collision). We flexibly parameterize the properties of the collision (e.g., the collision location) and use simple models for the three-dimensional velocity ejection field expected from each model to generate simulated families. These are compared to observed Kuiper Belt Objects using Bayesian parameter inference, including a mixture model that allows for interlopers from the background population. After testing our methodology, we find the best match to the observed Haumeans is an isotropic ejection field with a typical velocity of 150 m s$^{-1}$. The graze-and-merge and satellite collision hypotheses are disfavored. Including these constraints, we discuss the formation hypotheses in detail, including variations, some of which are tested. Some new hypotheses are proposed (a cratering collision and a collision where Haumea's upper layers are "missing") and scrutinized. We do not identify a satisfactory formation hypothesis, but we do propose several avenues of additional investigation. In addition, we identify many new candidate Haumeans and dynamically confirm 7 of them as consistent with the observed family. We confirm that Haumeans have a shallow size distribution and discuss implications for the identification of new Haumeans.

description: State-of-the-art Graph Neural Networks (GNNs) have limited scalability with respect to the graph and model sizes. On large graphs, increasing the model depth often means exponential expansion of the scope (i.e., receptive field). Beyond just a few layers, two fundamental challenges emerge: 1. degraded expressivity due to oversmoothing, and 2. expensive computation due to neighborhood explosion. We propose a design principle to decouple the depth and scope of GNNs -- to generate representation of a target entity (i.e., a node or an edge), we first extract a localized subgraph as the bounded-size scope, and then apply a GNN of arbitrary depth on top of the subgraph. A properly extracted subgraph consists of a small number of critical neighbors, while excluding irrelevant ones. The GNN, no matter how deep it is, smooths the local neighborhood into informative representation rather than oversmoothing the global graph into "white noise". Theoretically, decoupling improves the GNN expressive power from the perspectives of graph signal processing (GCN), function approximation (GraphSAGE) and topological learning (GIN). Empirically, on seven graphs (with up to 110M nodes) and six backbone GNN architectures, our design achieves significant accuracy improvement with orders of magnitude reduction in computation and hardware cost.

description: Stacks of superconducting tapes can trap much higher magnetic fields than conventional magnets. This makes them very promising for motors and generators. However, ripple magnetic fields in these machines present a cross-field component that demagnetizes the stacks. At present, there is no quantitative agreement between measurements and modeling of cross-field demagnetization, mainly due to the need of a 3D model that takes the end effects and real micron-thick superconducting layer into account. This article presents 3D modeling and measurements of cross-field demagnetization in stacks of up to 5 tapes and initial magnetization modeling of stacks of up to 15 tapes. 3D modeling of the cross-field demagnetization explicitly shows that the critical current density, $J_c$, in the direction perpendicular to the tape surface does not play a role in cross-field demagnetization. When taking the measured anisotropic magnetic field dependence of $J_c$ into account, 3D calculations agree with measurements with less than 4 % deviation, while the error of 2D modeling is much higher. Then, our 3D numerical methods can realistically predict cross-field demagnetization. Due to the force-free configuration of part of the current density, J, in the stack, better agreement with experiments will probably require measuring the Jc anisotropy for the whole solid angle range, including $J$ parallel to the magnetic field.

Next, we exemplify by considering the compressible Euler equations in primitive variables, transform them to skew-symmetric form and show how to obtain energy and entropy estimates. Finally we show that the skew-symmetric formulation lead to energy and entropy stable discrete approximations if the scheme is formulated on summation-by-parts form.

Complexation of DNA with positive spheres: phase diagram of charge inversion and reentrant condensation

description: The phase diagram of a water solution of DNA and oppositely charged spherical macroions is studied. DNA winds around spheres to form beads-on-a-string complexes resembling the chromatin 10 nm fiber. At small enough concentration of spheres these "artificial chromatin" complexes are negative, while at large enough concentrations of spheres the charge of DNA is inverted by the adsorbed spheres. Charges of complexes stabilize their solutions. In the plane of concentrations of DNA and spheres the phases with positive and negative complexes are separated by another phase, which contains the condensate of neutral DNA-spheres complexes. Thus when the concentration of spheres grows, DNA-spheres complexes experience condensation and resolubilization (or reentrant condensation). Phenomenological theory of the phase diagram of reentrant condensation and charge inversion is suggested. Parameters of this theory are calculated by microscopic theory. It is shown that an important part of the effect of a monovalent salt on the phase diagram can be described by the nontrivial renormalization of the effective linear charge density of DNA wound around a sphere, due to the Onsager-Manning condensation. We argue that our phenomenological phase diagram or reentrant condensation is generic to a large class of strongly asymmetric electrolytes. Possible implication of these results for the natural chromatin are discussed.

description: In this paper, we develop a convolutional neural network model to predict the mechanical properties of a two-dimensional checkerboard composite quantitatively. The checkerboard composite possesses two phases, one phase is soft and ductile while the other is stiff and brittle. The ground-truth data used in the training process are obtained from finite element analyses under the assumption of plane stress. Monte Carlo simulations and central limit theorem are used to find the size of the dataset needed. Once the training process is completed, the developed model is validated using data unseen during training. The developed neural network model captures the stiffness, strength, and toughness of checkerboard composites with high accuracy. Also, we integrate the developed model with a genetic algorithm (GA) optimizer to identify the optimal microstructural designs. The genetic algorithm optimizer adopted here has several operators, selection, crossover, mutation, and elitism. The optimizer converges to configurations with highly enhanced properties. For the case of the modulus and starting from randomly-initialized generation, the GA optimizer converges to the global maximum which involves no soft elements. Also, the GA optimizers, when used to maximize strength and toughness, tend towards having soft elements in the region next to the crack tip.

description: The credit crisis broken out in 2008 changed persistently the financial branch as well as the image of the economy of the world on the basis of this, it can be claimed that its influence has still had significant impact on our everyday life. Due to the fact that the recession has indirect or direct effect on all branches, ultimately the credit crisis has become a severe recession, which has affected sensitively almost all members of the economy. By now, however, something has changed sensibly. According to the statistics of the KSH, the expansion of the GDP of the fourth quarter of the year 2014 of our country was better than expected: it has increased 3.4%. This result means 3.6% GDP growth in relation to a whole year. Concerning consumption, increase can be realized. The real consumption of the households has gone up with 2% comparing the same period of the preceding year. The most consumption centred items of the economy, the households transformed their consumption habits as the result of the protracted crisis. The crisis management behaviours of the population is henceforward characterised by keeping back the expenses besides the bare necessities, which calls new and creative consumption techniques into being. Moreover, frequent saving methods are the holding back of the overhead consumption as well as the giving up the consumer goods temporarily. Among the real consumption components, the consumption expense representing the highest rate increased by 1.9% in 2014. It would appear that the crucial period of the crisis has already been behind us although most of the consumers cannot sit back since the recovery is not so obvious. It is enough if we take the instructions aiming at the adjustments of the budget into consideration, which have indirect impacts on the consumer-being. This study is making an attempt at showing the route of the Hungarian consumers from the instant consumer desire to rational consumption habit forced to sacrifice.

description: Cluster perturbation theory is a technique for calculating the spectral weight of Hubbard models of strongly correlated electrons, which combines exact diagonalizations on small clusters with strong-coupling perturbation theory at leading order. It is exact in both the strong- and weak-coupling limits and provides a good approximation to the spectral function at any wavevector. Following the paper by Sénéchal et al. (Phys. Rev. Lett. {\bf 84}, 522 (2000)), we provide a more complete description and derivation of the method. We illustrate some of its capabilities, in particular regarding the effect of doping, the calculation of ground state energy and double occupancy, the disappearance of the Fermi surface in the $t-t'$ Hubbard model, and so on. The method is applicable to any model with on-site repulsion only.

description: Traffic state data, such as speed, volume and travel time collected from ubiquitous traffic monitoring sensors require advanced network level analytics for forecasting and identifying significant traffic patterns. This paper leverages diverse traffic state datasets from the Caltrans Performance Measurement System (PeMS) hosted on the open benchmark and achieved promising performance compared to well recognized spatial-temporal models. Drawing inspiration from the success of hierarchical architectures in various Artificial Intelligence (AI) tasks, we integrate cell and hidden states from low-level to high-level Long Short-Term Memory (LSTM) networks with an attention pooling mechanism, similar to human perception systems. The developed hierarchical structure is designed to account for dependencies across different time scales, capturing the spatial-temporal correlations of network-level traffic states, enabling the prediction of traffic states for all corridors rather than a single link or route. The efficiency of designed attention-based LSTM is analyzed by ablation study. Comparative results with baseline LSTM models demonstrate that the Hierarchical Attention LSTM (HierAttnLSTM) model not only provides higher prediction accuracy but also effectively forecasts unusual congestion patterns. Data and code are made publicly available to support reproducible scientific research.

description: The European waste management principles are laid down in EU documents. They also include specific targets that Member States have to fulfil within a certain period of time. The three most important documents in this field are the Waste Framework Directive, the Landfill Directive and the Packaging and Packaging Waste Directive. The provisions for municipal waste are defined in the Waste Framework Directive that sets the tasks to be completed by 2020. The comparison of performance indicators of Member States shows that there are significant differences. Having examined the relevant statistics, it is visible that the Central European countries (Visegrad4 countries) have similar performance. Their indexes are considerably below the top performers' ones. Therefore, it is useful to compare the public service waste management system of two groups above (top performers and V4 countries), because the municipal solid waste produces the most significant quantity and the most complex waste stream. The national waste management systems must conform to EU legislation; however there is a possibility for a free choice in the detailed rules. Through the comparison of the respective waste management systems the similarities and differences are analyzed in this paper.

description: General methods of quantitative and qualitative continuity analysis of characteristics of composite quantum systems are described. Several modifications of the Alicki-Fannes-Winter method are considered, which make it applicable to a wide class of characteristics in both finite-dimensional and infinite-dimensional cases. A new approximation method for obtaining local continuity conditions for various characteristics of quantum systems is proposed and described in detail. This method allows us to prove several general results (Simon-type dominated convergence theorem, the theorem about preserving continuity under convex mixtures, etc.).
 Uniform continuity bounds and local continuity conditions for basic characteristics of composite quantum systems are presented. Along with the results obtained earlier by different authors, a number of new results proved by the proposed methods are described.

description: We present an in-depth exploration of the phenomenon of dynamical friction in a universe where the dark matter is composed entirely of so-called Fuzzy Dark Matter (FDM), ultralight bosons of mass $m\sim\mathcal{O}(10^{-22})\,$eV. We review the classical treatment of dynamical friction before presenting analytic results in the case of FDM for point masses, extended mass distributions, and FDM backgrounds with finite velocity dispersion. We then test these results against a large suite of fully non-linear simulations that allow us to assess the regime of applicability of the analytic results. We apply these results to a variety of astrophysical problems of interest, including infalling satellites in a galactic dark matter background, and determine that \emph{(1)}~for FDM masses $m\gtrsim 10^{-21}\, {\rm eV}\, c^{-2}$, the timing problem of the Fornax dwarf spheroidal's globular clusters is no longer solved and \emph{(2)}~the effects of FDM on the process of dynamical friction for satellites of total mass $M$ and relative velocity $v_{\rm rel}$ should require detailed numerical simulations for $\left(M/10^9~M_{\odot}\right) \left(m/10^{-22}~{\rm eV}\right)\left(100~{\rm km}~{\rm s}^{-1}/v_{\rm rel}\right) \sim 1$, parameters which would lie outside the validated range of applicability of any currently developed analytic theory, due to transient wave structures in the time-dependent regime.

description: 388 hot subdwarf stars have been identified by using the Hertzsprung-Russell (HR) diagram built from the second data release (DR2) of the Gaia mission. By analyzing their observed LAMOST spectra, we characterized 186 sdB, 73 He-sdOB, 65 sdOB, 45 sdO, 12 He-sdO and 7 He-sdB stars. The atmospheric parameters of these stars (e.g., T eff , log g, log(nHe/nH)) are obtained by fitting the hydrogen (H) and helium (He) line profiles with synthetic spectra calculated from non-Local Thermodynamic Equilibrium (non-LTE) model atmospheres. Among these stars, we have 135 new identified hot subdwarfs which have not been cataloged before. Although 253 stars appear in the catalog by Geier et al. (2017) , but only 91 of them have atmospheric parameters. Together with the 294 hot subdwarf stars found by Lei et al. (2018), we identified 682 hot subdwarf stars in total by using the Gaia HR-diagram and LAMOST spectra. These results demonstrate the efficiency of our method to combine large surveys to search for hot subdwarf stars. We found a distinct gap in our He-sdOB stars based on their He abundance, which is also presented in extreme horizontal branch (EHB) stars of the globular cluster (GC) ω Cen. The number fraction of the sample size for the two sub-groups is very different between the two counterparts. However, the distinct gap between the H-sdB stars and He-sdOB stars in ω Cen is not visible in our sample. More interestingly, the He-sdB population with the highest He abundance in our sample is completely missing in ω Cen. The discrepancy between our field hot subdwarf stars and the EHB stas in ω Cen indicate different origins for the two counterparts.

description: Nowadays transparency and monitoring are two of the most important expectations towards organisations. But the fulfilment of these expectations imposes a major challenge for the participants of the economy. Consumer expectations are twofold: they want food to be harmless (food safety) and they want good quality food (nutritional value, smell etc.) for the price they pay. The more developed the economy of a country the more intense the customer expectations are. At the end of 2014 the food labelling regulations became more strict. As a result of changes retailers first will have more to do but customers will be more informed regarding food allergens. To introduce the changes in food labelling regulations in Hungary mostly Hungarian scholarship was used. The literature review is followed by a primary research in order to reveal the relations of costumers’ healthy nutrition A questionnaire survey was completed regarding the food buying practices of customers then an observation was carried out to shed light on how Hungarian food retailer chains adjusted to changes in food labelling regulations. ---------------------------------------------------------------- Átláthatóság és nyomonkövethetőség. Ez napjaink egyik legfontosabb elvárása, melynek megvalósítása (vagy megvalósításának kísérlete) igen jelentős kihívás elé állítja a gazdaság szereplőit. A fogyasztó az élelmiszertől egyrészt azt várja, hogy annak elfogyasztására számára ne jelentsen veszélyt (biztonságos legyen), másrészről pénzéért megfelelő minőségű (tápértékű, ízű, illatú stb.) élelmiszert szeretne kapni. Minél fejlettebb egy ország gazdasága, ez az igény annál markánsabban jelentkezik. Magyarországon 2014 végén szigorodtak a jelöléssel kapcsolatos szabályok, mely helyzet kezdetben plusz feladatok elő állítja a kereskedőket, viszont segíti a fogyasztók tájékozódását az allergén összetevők feltárásában. A magyar helyzet bemutatásához a (javarészt magyar) szakirodalmi források felhasználása után primer kutatást végeztünk annak érdekében, hogy felmérjük a fogyasztók egészséges táplálkozáshoz való viszonyát. Egyrészt kérdőíves kutatást készítettünk a fogyasztók élelmiszervásárlási szokásainak megismerésére, másrészt megfigyelést végeztünk annak feltárására, hogy a jelentősebb Magyarországon működő élelmiszerláncokban hogyan valósították meg a módosult jelölésbeli előírásokat.

Black hole mass and binary model for BL Lac object OJ 287

description: Recent intensive observations of the BL Lac object OJ 287 raise a lot of questions on the models of binary black holes, processing jets, rotating helical jets and thermal instability of slim accretion disks. After carefully analyzing their radio flux and polarization data, Valtaoja et al. (\cite{valtaoja00}) propose a new binary model. Based on the black hole mass of $4 \times 10^8 {\rm M_\odot}$ estimated with the tight correlations of the black hole masses and the bulge luminosity or central velocity dispersion of host galaxies, we computed the physical parameters of the new binary scenario. The impact of the secondary on the accretion disk around the primary black hole causes strong shocks propagating inwards and outwards, whose arrival at the jet roots is identified with the rapid increase of optical polarization and the large change of polarization angle at about 0.30 yr after the first main optical flare. An increase of optical polarization, a large rotation of positional angle and a small synchrotron flare at 2007.05 between the optical outbursts at 2006.75 and 2007.89 are expected by the model. With the estimated parameters, we predicated an increase of $γ$-ray flux appearing about 5 days after the first optical/IR peak, which is consistent with the EGRET observations.

description: This paper studied the impact of fiscal subsidies on the participation rate and contributions of the rural residents in the China’s New Rural Pension Scheme (NRPS) program using a natural experiment, where the fiscal subsidies includes the incentive pension and the matching subsidy. The results showed that incentive pension can significantly improve the rural residents' participation rates, but participation rate of young residents are less than the older residents. We also showed that matching subsidy does not affect the rural residents' participation rates and contributions significantly. Our results suggest that the current fiscal subsidies play an important role in the establishment and expansion of the NRPS program, but have not increased the participation rate of younger people, which was one of the initial goal of NRPS.

description: An obstacle representation of a graph $G$ consists of a set of polygonal obstacles and a drawing of $G$ as a visibility graph with respect to the obstacles: vertices are mapped to points and edges to straight-line segments such that each edge avoids all obstacles whereas each non-edge intersects at least one obstacle. Obstacle representations have been investigated quite intensely over the last few years. Here we focus on outside-obstacle representations (OORs) that use only one obstacle in the outer face of the drawing. It is known that every outerplanar graph admits such a representation.
 We strengthen this result by showing that every (partial) 2-tree has an OOR. We also consider restricted versions of OORs where the vertices of the graph form a convex polygon or even a regular polygon. We characterize when the complement of a tree and when a complete graph minus a simple cycle admits a convex OOR. We construct regular OORs for all (partial) outerpaths, cactus graphs, and grids.

description: We propose the idea of a "spinguide", i.e. the semiconductor channel which is surrounded with walls from the diluted magnetic semiconductor (DMS) with the giant Zeeman splitting which are transparent for electrons with the one spin polarization only. These spinguides may serve as sources of a spin-polarized current in non-magnetic conductors, ultrafast switches of a spin polarization of an electric current and, long distances transmission facilities of a spin polarization (transmission distances can exceed a spin-flip length). The selective transparence of walls leads to new size effects in transport.

description: The present study analysed the technical efficiency and technological gaps (TGR/MTR) in three major beef cattle production systems in Nigeria, using the stochastic metafrontier approach. The usual methods of dealing with technological differences makes it difficult to separate “technology gaps” from technical inefficiency within a given system, hence the need for an analytical framework such as metafrontier which allows us to distinguish between the two. Results show that technical inefficiency exists in the three production systems but the ranching system is more efficient, in that it has a higher MTR. The average pooled technical efficiency TE with respect to the metafrontier was estimated to be 0.56; this suggests that there is scope to improve beef output in Nigeria by up to 44% of the total potential, giving existing technologies and inputs.
Can Chameleon fields be the source of both the dark energy dipole and the CMB dipole?

description: Recent research reveals that the Local Group is in motion towards $(l, b) = (276, 30)$ relative to the cosmic background radiation, manifesting a velocity of 600 $\frac{km}{s}$ a phenomenon recognized as the cosmic background radiation dipole or CMB dipole. Despite its well-documented nature, the precise cause of this peculiar motion remains elusive. High mass-density regions, such as galactic superclusters, stand out among the potential contributors to this cosmic flow. This paper employs chameleon fields to investigate anisotropies on both small and large scales. The data utilized in this study comprise Type Ia supernovae from the Pantheon catalog, totaling 1,048 supernovae within the redshift range of $0.015 < z < 2.3$. The analysis of bulk flow at various redshifts has yielded noteworthy discoveries. On a smaller scale (less than 150 Mpc), the movement direction of the Local Group coincides with that of the bulk flow. On a larger scale, the bulk flow direction corresponds to the direction of the dark energy dipole. This implies that the anisotropy at the local scale originates from the same source as the anisotropy observed on a larger scale.

description: We perform a NNLO (and a LO) global parton analysis in which we include the new precise data for deep inelastic scattering from HERA and for inclusive jet production at the Tevatron, together with the improved knowledge of the three-loop splitting functions. The results are compared with our recent NLO analyses. The LO fit produces significantly worse results in general, but gives a surprisingly good fit to the Tevatron high-E_T jet data. For the approximate NNLO analysis we notice a slight improvement in the quality of the global fit, and find that the partons are changed by up to 10% at Q^2=10 GeV^2$, in particular in the x<0.01 regime.
