description: Deep Reinforcement Learning (RL) is a promising approach for adaptive robot control, but its current application to robotics is currently hindered by high sample requirements. To alleviate this issue, we propose to exploit the symmetries present in robotic tasks. Intuitively, symmetries from observed trajectories define transformations that leave the space of feasible RL trajectories invariant and can be used to generate new feasible trajectories, which could be used for training. Based on this data augmentation idea, we formulate a general framework, called Invariant Transform Experience Replay that we present with two techniques: (i) Kaleidoscope Experience Replay exploits reflectional symmetries and (ii) Goal-augmented Experience Replay which takes advantage of lax goal definitions. In the Fetch tasks from OpenAI Gym, our experimental results show significant increases in learning rates and success rates. Particularly, we attain a 13, 3, and 5 times speedup in the pushing, sliding, and pick-and-place tasks respectively in the multi-goal setting. Performance gains are also observed in similar tasks with obstacles and we successfully deployed a trained policy on a real Baxter robot. Our work demonstrates that invariant transformations on RL trajectories are a promising methodology to speed up learning in deep RL.

description: K+ meson production in pA (A = C, Cu, Au) collisions has been studied using the ANKE spectrometer at an internal target position of the COSY-Juelich accelerator. The complete momentum spectrum of kaons emitted at forward angles, theta < 12 degrees, has been measured for a beam energy of T(p)=1.0 GeV, far below the free NN threshold of 1.58 GeV. The spectrum does not follow a thermal distribution at low kaon momenta and the larger momenta reflect a high degree of collectivity in the target nucleus.

description: We obtained K-band spectroscopy of the brightest members of the cluster VVV CL074 in order to identify the massive star population. We also determined the stellar properties of the cluster's massive stars to better quantify the evolutionary sequences linking different types of massive stars. We collected integral field spectroscopy of selected fields in the cluster VVV CL074 with SINFONI on the ESO/VLT. We performed a spectral classification based on the K-band spectra and comparison to infrared spectral atlases. We determined the stellar parameters of the massive stars from analysis with atmosphere models computed with the code CMFGEN. We uncover a population of 25 early-type (OB and Wolf-Rayet) stars, 19 being newly discovered by our observations out of which 15 are likely cluster members. The cluster's spectrophotometric distance is 10.2+/-1.6 kpc, placing it close to the intersection of the galactic bar and the Norma arm, beyond the galactic center. This makes VVV CL074 one the farthest young massive clusters identified so far. Among the massive stars population, three objects are Wolf-Rayet stars, the remaining are O and B stars. From the Hertzsprung-Russell diagram we find that most stars have an age between 3 and 6 Myr according to the Geneva evolutionary tracks. WN8 and WC8-9 stars are the descendants of stars with initial masses between 40 and 60 Msun. The massive star population of VVV CL074 is very similar to that of the cluster DBS2003-179 and to a lesser extent to that of the Quintuplet cluster, indicating the same age. The central cluster of the Galaxy is ~3 Myr older. From the comparison of the massive stars populations in these four clusters, one concludes that galactic stars with an initial mass in the range 40 to 60 Msun likely go through a WN8-9 phase.

description: Customer is important equity of an enterprise. Customer equity is the total combined customer lifetime values of all of the company’s customers. In the context of invasion of transnational seed companies, how to cope with huge crisis and challenge is a problem to be solved by national companies and government. From the perspective of customer equity driving factors and sub-driving factors, this paper made an empirical study on transnational and national maize seed enterprises using principal component analysis (PCA). Results indicated that the driving factors for customer equity of national and transnational maize seed enterprises are basically similar, while there are large differences in ranking of importance of principal components. Besides, there are great differences in sub-driving factors of customer equity.

description: We analyze PLANET and MACHO observations of MACHO 99-BLG-47, the first nearly-normal microlensing event for which high signal-to-noise-ratio data reveal a well-covered, short-duration anomaly. This anomaly occurs near the the peak of the event. Short-duration anomalies near the peak of otherwise normal events are expected to arise both from extreme-separation (either very close or very wide), roughly equal-mass binary lenses, and from planetary systems. We show that the lens of MACHO 99-BLG-47 is in fact an extreme-separation binary, not a planetary system, thus demonstrating for the first time that these two important classes of events can be distinguished in practice. However, we find that the wide-binary and close-binary lens solutions fit the data equally well, and cannot be distinguished even at Delta-chi^2=1. This degeneracy is qualitatively much more severe than the one identified for MACHO 98-SMC-1 because the present degeneracy spans two rather than one dimension in the magnification field and does not require significantly different blending fractions. In the appendix, we explore this result, and show that it is related to the symmetry in the lens equation.

description: Micromagnetics simulations require accurate approximation of the magnetization dynamics described by the Landau-Lifshitz-Gilbert equation, which is nonlinear, nonlocal, and has a non-convex constraint, posing interesting challenges in developing numerical methods. In this paper, we propose two second-order semi-implicit projection methods based on the second-order backward differentiation formula and the second-order interpolation formula using the information at previous two temporal steps. Unconditional unique solvability of both methods is proved, with their second-order accuracy verified through numerical examples in both 1D and 3D. The efficiency of both methods is compared to that of another two popular methods. In addition, we test the robustness of both methods for the first benchmark problem with a ferromagnetic thin film material from National Institute of Standards and Technology.

description: In this paper is given analysis of reciprocity between level of development of economy and results of transition on example of ex-SFRY countries in period from 1945 until 2008. Analysed period is divided in three sub-periods. First sub-period of Kingdom of Yugoslavia is marked with low level of economic growth, just over the rate of natural increase of number of inhabitants and domination of foreign capital in key areas of economy. In first sub-period, SFRY achieved high rates of economy grow, approximately the same level in all republics, with increased country obligations abroad and with hint of economic crises that arise in 1990’s. Second sub-period marked disintegration of SFRY, civil war on area of Croatia and Bosnia and Herzegovina, negative rate of economic growth in first and mild economic recovery in second half of 1990’s. However, on the contrary of ex- SFRY countries, they managed to fulfil full economic stability and high rates of economic growth. Today those countries are members of European Union. Period after 2000 (Third fourth sub-period) is marked with high rates of economic growth in almost all ex-SFRY countries, along with stabilisation of other indicators and adjustment with criteria from Maastricht for EU accession. Serbia has achieved good results in this sub-period, comparing to previous, but they are still lower from those achieved at the beginning of 1990’s.

description: After summarizing basic features of self-organization such as entropy export, feedbacks and nonlinear dynamics, we discuss several examples in biology. The main part of the paper is devoted to a model of active Brownian motion that allows a stochastic description of the active motion of biological entities based on energy consumption and conversion. This model is applied to the dynamics of swarms with external and interaction potentials. By means of analytical results, we can distiguish between translational, rotational and amoebic modes of swarm motion. We further investigate swarms of active Brownian particles interacting via chemical fields and demonstrate the application of this model to phenomena such as biological aggregation and trail formation in insects.

description: Hybrid lead halide perovskites with 2D stacking structures have recently emerged as promising materials for optoelectronic applications. We report a method for growing 2D nanosheets of hybrid lead halide perovskites (I, Br and Cl), with tunable lateral sizes ranging from 0.05 to 8 microns, and a structure consisting of n stacked monolayers separated by long alkylamines, tunable from bulk down to n=1. The key to obtaining such a wide range of perovskite properties hinged on utilizing the respective lead halide nanosheets as precursors in a hot-injection synthesis that afforded careful control over all process parameters. The layered, quantum confined (n small than 4) nanosheets were comprised of major and minor fractions with differing n. Energy funneling from low to high n (high to low energy) regions within a single sheet, mediated by the length of the ligands between stacks, produced photoluminescent quantum yields as high as 49 percent. These large, tunable 2D nanosheets could serve as convenient platforms for future high efficiency optoelectronic devices.

description: Deep reinforcement learning algorithms have been successfully applied to a range of challenging control tasks. However, these methods typically struggle with achieving effective exploration and are extremely sensitive to the choice of hyperparameters. One reason is that most approaches use a noisy version of their operating policy to explore - thereby limiting the range of exploration. In this paper, we introduce Collaborative Evolutionary Reinforcement Learning (CERL), a scalable framework that comprises a portfolio of policies that simultaneously explore and exploit diverse regions of the solution space. A collection of learners - typically proven algorithms like TD3 - optimize over varying time-horizons leading to this diverse portfolio. All learners contribute to and use a shared replay buffer to achieve greater sample efficiency. Computational resources are dynamically distributed to favor the best learners as a form of online algorithm selection. Neuroevolution binds this entire process to generate a single emergent learner that exceeds the capabilities of any individual learner. Experiments in a range of continuous control benchmarks demonstrate that the emergent learner significantly outperforms its composite learners while remaining overall more sample-efficient - notably solving the Mujoco Humanoid benchmark where all of its composite learners (TD3) fail entirely in isolation.

The accuracy and validity of the proposed relations is checked for the ECQF Hamiltonian of the IBM-1 in the whole parameter space of the Casten triangle. Furthermore these relations are successfully tested for low-lying collective states in nuclei for which all relevant data is available.

description: Improvement of production on agricultural farms as an extension goal, in fact, implies change in attitudes, opinions as well as farmers behaviour. Such changes are achievable through the process of adoptation of new knowledge, technologies and know-hows which enable farmer to solve problems of agricultural production. Extension agent has a task to facilitate such process. As a basic mechanism of diffusion of needed knowledge and know-hows is use of extension methods. The paper focuses on work of extension agents in Agricultural Extension Service of Autonomus Province of Vojvodina. Data for the analysis are collected by Extension service Typology from July 2007. to December 2008. The aim of the paper is to indicate the importance of complementary use of extension methods.

description: We evaluate the matrix element of $\bar{q} q$ in hadron states on a lattice. We find substantial mixing of the connected and disconnected contributions so that the lattice result that the disconnected contribution to the nucleon is large does not imply that the $\bar{s} s$ content is large. This has implications for dark matter searches.

Evidence against non-gravitational acceleration of 1I/2017 U1 `Oumuamua

Publisher: name: arXiv
Year: 2019
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: Micheli, et al. (2018) reported that a seven-parameter fit to the orbit of 1I/2017 U1 `Oumuamua indicated a non-gravitational acceleration in the anti-Solar direction, and attributed it to recoil from comet-like outgassing. The implied gas to dust ratio is at least 100 times greater than that of known Solar System comets. The reported collapse of the scatter of nearly contemporaneous coordinate residuals upon inclusion of the non-gravitational term in the orbital fits is difficult to understand. There are grounds for skepticism.

description: In contemporary business environment when Serbian joining to European Union is expected, enterprises competitiveness significantly depends on determination and application of appropriate developmental policy. To apply developmental policy it is very important to provide appropriate financing sources. Therefore, in this paper is analyzed situation that face most of Serbian fruit producers. The producers (within their developmental policy) put on first place construction of appropriate coolers. In such a way it is possible to facilitate expansion to European market and to achieve higher fruit prices. Cooler construction requires significant financial resources, thus in the paper have been analyzed economic profitability and financial feasibility of such investment. In that sense an example of container cooler for apple storage has been used as a variant which is the most common in practice. It is determined that cooler construction is economically profitable and financially feasible, while most of the investment could be financed by commercial bank loans. Construction of such coolers would significantly contribute to development of rural areas in Serbia.
The Future of Ultra High Energy Cosmic Rays

Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Contrary to earlier expectations, several cosmic ray events with energies above $10^{20}$ eV have been reported by a number of ultra-high energy cosmic ray observatories. According to the AGASA experiment, the flux of such events is well above the predicted Greisen-Zatsepin-Kuzmin cutoff due to the pion production of extragalactic cosmic ray protons off the cosmic microwave background. In addition to the relatively high flux of events, the isotropic distribution of arrival directions and an indication of small scale clustering strongly challenge all models proposed to resolve this puzzle. We discuss how the GZK cutoff is modified by the local distribution of galaxies and how astrophysical proton sources with soft injection spectra are ruled out by AGASA data. Sources with hard injection spectrum are barely allowed by the observed spectrum. If the most recent claims by AGASA that the highest energy events are due to clustered nuclei are confirmed, the most plausible explanation are astrophysical sources with very hard spectra such as extragalactic unipolar inductors. In addition, extragalactic magnetic fields need to be well below the current nano-Gauss upper limits. Alternatively, if the primaries are not nuclei, the need for new physics explanations is paramount. We present an overview of the theoretical proposals along with their most general signatures to be tested by upcoming experiments.

A Framework for Avoiding the Open Research Data Dump (AFFORD)
Creators: name: Center for Reproducible Science
name: The Interface Group
Publisher: name: Zenodo
Year: 2024

description: The project A Framework for Avoiding the Open Research Data Dump (AFFORD) aims at designing a sustainable support framework to lower the barriers to publishing data and other research outputs in an accessible form by bundling know-how, workflows, and tools under the umbrella of one organizational entity. It is a collaboration between The Interface Group and the Center for Reproducible Science of the University of Zurich. It uses the Swiss National Science Foundation FABRIC4 project as reference, accompanying this multi-center research endeavour through the full cycle of generating Open Research Data (ORD), from experiment planning to publishing. This project-based, data-driven approach will help the framework reach a sufficient level of maturity before it is made available to all university researchers.

The project is led by  Vartan Kurtcuoglu (The Interface Group, Department of Physiology, University of Zurich) and Leonhard Held (Center for Reproducible Science, University of Zurich)

description: This paper presents one of the models on determining the economic effects of production of conifer and deciduous seedlings. The model of cash flow is applied and used as dynamic method based on discount technique. Presented model allows assessment of cost-effectiveness of investments in specific conditions of production; this cost account has advantages in agricultural productions relative to traditional account. Derived results provide information on the income, costs of raising and care of plantation used for afforestation of land. Data are current and can be applied in the calculation of the required financial capital for the afforestation of land in Serbia, which lags behind the average covered with trees in the world and Europe. Afforestation of land has a wider social significance. Except the basic ecological function, has economic and recreational importance. It is realistic to expect that within the agro-economic policy of the state envisage special measures subsidies for manufacturers of conifer and deciduous seedlings. The aim of this paper is an indication of the importance of agro-economic analysis in strategic decision-making in the reforestation of land.

description: Key problem which started up development of the sustainable agriculture concept, especially in high-developed countries, is uncontrolled application of pesticides and mineral fertilizers in conventional agriculture. The problems, caused by excessive use of synthetic chemical means, have been visible long since and it is very anxious. One of the important elements of sustainable agriculture concept is appliance of alternative, but also enough efficient methods of plant protection, and, among others, biological methods are some of them. Biological control by itself is not sufficient to solve the problems of undesirable organisms in crops' existence, but in combination with other methods of sustainable development, it results satisfactorily. In this paper work we tried to point out to some reasons of actualization and advantages of biological control method, as a new one and, for the environment, harmless method in crops protection.

description: We argue that chaotic power-law interacting systems have emergent limits on information propagation, analogous to relativistic light cones, which depend on the spatial dimension $d$ and the exponent $α$ governing the decay of interactions. Using the dephasing nature of quantum chaos, we map the problem to a stochastic model with a known phase diagram. A linear light cone results for $α\ge d+1/2$. We also provide a Lévy flight (long-range random walk) interpretation of the results and show consistent numerical data for 1d long-range spin models with 200 sites.
