description: : The use and development of renewable energy sources is one of the basic issues in the Poland’s Energy Policy until 2030. It is planned that the renewable energy technologies should constitute 25.4% of the overall power capacity in 2020. Solid biomass dominates in the structure of the production of renewable energy, whereas biofuels and solar energy constitute a fraction of one percent. The analysis of the dynamics of changes in the consumption of energy indicates the constant use of electricity, and a decreasing energy intensities GDP. The production of electricity based on renewable energy is increasing dynamically (indicated by the exponential form of the trend line) and the short-term forecast has a small error of predication – below 15%.

description: A generalised method of using feedback to control Bose-Einstein condensates is introduced. The condensates are modelled by the Gross-Pitaevskii equation, so only semiclassical fluctations can be suppressed, and back-action from the measurement is ignored. We show that for any available control, a feedback scheme can be found to reduce the energy while the appropriate moment is still dynamic. We demonstrate these schemes by considering a condensate trapped in a harmonic potential that can be modulated in strength and position. The formalism of our feedback scheme also allows the inclusion of certain types of non-linear controls. If the non-linear interaction between the atoms can be controlled via a Feshbach resonance, we show that the feedback process can operate with a much higher efficiency.

description: Bio-economy requires the participation that engages societies, including the local communities. In this context, the aim of the study is to recognize the opinion of the local community regarding the legitimacy of the use of existing local renewable energy potential, which will take the appropriate actions in the field of RES for the full implementation of the bio-economy program. The study assumed that a considerable degree of acceptance of renewable energy sources can be a powerful argument in order to confirm the thesis that as a result of income growth and consumer demand the multiplier effect of the use of RES will appear, contributing to local development. The tests were performed using factual methods. Secondary research, indirect (desk research), carried out in the process of exploring the problem. Field research, direct primary research, enabled the acquisition of primary data to enable the implementation of the targets. In examining the opinions of the populations of krośnieńsko-przemyski area sought to determine the relationship between the local community to the possibility of the use of renewable energy sources at the local level. Recognized opinions allowed to determine whether there is approval, disapproval, or no opinion on the use of renewable energy sources. Substantial increase in the share of RES technologies in the surveyed communes of Przemysl and Krosno sub-regions should be based on agricultural biomass, forest biomass, wind energy, geothermal energy, and solar energy. Tested communities have different often divergent opinions as to the validity of the use of RES on the local level, nevertheless a large interest in modern technologies and renewable sources of their funding is observed. The local community in the majority wants to pursue undertakings in the field of renewable energy, mainly based on solar and wind energy. There is a need to further identify and develop local potentials, including the use of social energy from renewable sources.

description: Various suggestions exist for incorporating the strange quark into twisted mass QCD. One option for quenched simulations is to employ two twisted doublets, (u,d) and (c,s), with separate twist angles. Working in the isospin limit, preliminary results for the quenched spectrum of strange hadrons are presented, with both twist angles tuned to pi/2. Splittings within the mass multiplets provide some insight into the symmetry breaking effects of twisted mass lattice QCD.

The Link between Warm Molecular Disks in Maser Nuclei and Star Formation near the Black Hole at the Galactic Center

description: The discovery of hundreds of young, bright stars within a parsec from the massive black hole at the center of the Galaxy presents a challenge to star formation theories. The requisite Roche densities for the gravitational collapse of gas clouds are most naturally achieved in accretion disks. The water maser sources in Keplerian rotation in the nuclei of NGC4258, NGC1068, and the Circinus galaxy indicate the presence of warm, extended, molecular accretion disks around black holes similar in mass to the one at the Galactic center. Here we argue that the current conditions in the maser nuclei, and those near the Galactic center, represent two consecutive, recurrent phases in the life cycle of the nucleus of a typical gas-rich spiral bulge. The warm molecular disks that give rise to the observed maser emission fragment into stellar-size objects. The stellar masses, their orbital geometry, and the total number of stars thus formed are consistent with the values identified at the Galactic center. The stars tend to form in compact groups resembling the IRS 13 complex that dominates the stellar light in the neighborhood of the black hole.

description: A dynamical epidemic model optimized using genetic algorithm and cross validation method to overcome the overfitting problem is proposed. The cross validation procedure is applied so that available data are split into a training subset used to fit the algorithm's parameters, and a smaller subset used for validation. This process is tested on the countries of Italy, Spain, Germany and South Korea before being applied to Algeria. Interestingly, our study reveals an inverse relationship between the size of the training sample and the number of generations required in the genetic algorithm. Moreover, the enhanced compartmental model presented in this work is proven to be a reliable tool to estimate key epidemic parameters and non-measurable asymptomatic infected portion of the susceptible population in order to establish realistic nowcast and forecast of epidemic's evolution. The model is employed to study the COVID-19 outbreak dynamics in Algeria between February 25th and May 24th, 2020. The basic reproduction number and effective reproduction number on May 24th, after three months of the outbreak, are estimated to be 3.78 (95% CI 3.033-4.53) and 0.651 (95% CI 0.539-0.761) respectively. Disease incidence, CFR and IFR are also calculated. Numerical programs developed for the purpose of this study are made publicly accessible for reproduction and further use.

description: We consider an Einstein-Yang-Mills Lagrangian in a five dimensional space-time including a cosmological constant. Assuming all fields to be independent of the extra coordinate, a dimensional reduction leads to an effective (3+1)-dimensional Einstein-Yang-Mills-Higgs-dilaton model where the cosmological constant induces a Liouville potential in the dilaton field. We construct spherically symmetric solutions analytically in specific limits and study the generic solutions for vanishing dilaton coupling numerically. We find that in this latter case the solutions bifurcate with the branch of (Anti-) de Sitter-Reissner-Nordstrom ((A)dSRN) solutions.

description: Technologies such as virtual reality (VR), online databases, Geographic Information Systems (GIS), Building Information Modelling (BIM), Unmanned Aerial Vehicle (UAV), 4 D Computer-Aided Design (4 D CAD), wearable robotics have been adopted to improve construction site health and safety. However, little attempt has been made to map global research on construction health and safety technologies. Therefore, this paper conducts a review of technologies for construction health and safety management to reveal emerging research trends. A bibliometric review adopting a two-step literature selection method was conducted to compile relevant publications from the Scopus database. In total, 240 related papers were examined. VOSviewer was used to develop a co-occurrence network based on the bibliographic data obtained. The analysis focussed on co-authorship per country, country/region distribution, the num?ber of publications annually, publication source and source and trend of research topics. Findings revealed that emerging trends in construction health and safety technologies research focussed on pro?ject health and safety design and planning, visualisation and image processing for construction projects, digital technologies for project monitoring, information management and Internet of Things, automation and robotic systems, health and safety and accident prevention and structure evaluation.

description: The European Uniona and Poland aim to increase the role of renewbale energy sources and suppport it through programs encouraging the installation of solar colectors. This study presents preliminary results regarding knowledge about the renewable energy sources, subsidies for solar colectors and factors influencing such decision to install colectors among residents of five villages in Lubelskie Voivodship, the region with the most suitable natural conditions for solar energy utilization. Summary of responses from 93 respondetns shows that they have an average or good knowledge about solar energy, but the majority is not familiar with the solar colector subsidy program, while the lower energy costs, return on investment and colector prices are the most imnportant factors influencing the decision to purchase and install colectors. The preliminary nature of the study suggests that general inferences based on the observed tendencies ave to be treated with caution.

Bifurcation structure of two Coupled Periodically driven double-well Duffing Oscillators
Creators: name: Kenfack, Anatole
Publisher: name: arXiv
Year: 2003
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: The bifurcation structure of coupled periodically driven double-well Duffing oscillators is investigated as a function of the strength of the driving force $f$ and its frequency $Ω$. We first examine the stability of the steady state in linear response, and classify the different types of bifurcation likely to occur in this model. We then explore the complex behaviour associated with these bifurcations numerically. Our results show many striking departures from the behaviour of coupled driven Duffing Oscillators with single well-potentials, as characterised by Kozlowski et al \cite{k1}. In addition to the well known routes to chaos already encountered in a one-dimensional Duffing oscillator, our model exhibits imbricated period-doubling of both types, symmetry-breaking, sudden chaos and a great abundance of Hopf bifurcations, many of which occur more than once for a given driving frequency. We explore the chaotic behaviour of our model using two indicators, namely Lyapunov exponents and the power spectrum. Poincaré cross-sections and phase portraits are also plotted to show the manifestation of coexisting periodic and chaotic attractors including the destruction of $T^2$ tori doubling.

description: In this paper, we apply the Non-Orthogonal Multiple Access (NOMA) technique to improve the massive channel access of a wireless IoT network where solar-powered Unmanned Aerial Vehicles (UAVs) relay data from IoT devices to remote servers. Specifically, IoT devices contend for accessing the shared wireless channel using an adaptive $p$-persistent slotted Aloha protocol; and the solar-powered UAVs adopt Successive Interference Cancellation (SIC) to decode multiple received data from IoT devices to improve access efficiency. To enable an energy-sustainable capacity-optimal network, we study the joint problem of dynamic multi-UAV altitude control and multi-cell wireless channel access management of IoT devices as a stochastic control problem with multiple energy constraints. To learn an optimal control policy, we first formulate this problem as a Constrained Markov Decision Process (CMDP), and propose an online model-free Constrained Deep Reinforcement Learning (CDRL) algorithm based on Lagrangian primal-dual policy optimization to solve the CMDP. Extensive simulations demonstrate that our proposed algorithm learns a cooperative policy among UAVs in which the altitude of UAVs and channel access probability of IoT devices are dynamically and jointly controlled to attain the maximal long-term network capacity while maintaining energy sustainability of UAVs. The proposed algorithm outperforms Deep RL based solutions with reward shaping to account for energy costs, and achieves a temporal average system capacity which is $82.4\%$ higher than that of a feasible DRL based solution, and only $6.47\%$ lower compared to that of the energy-constraint-free system.

description: : The need to distinguish from the overall economy something which constitutes an important part of its animated nature, operating on the basis of the laws of nature, signifies noticing distinct rights and principles of the living world, of which man is part, from the inanimate world. The right of economy dominates within the living nature and it can be described as the creation of the highest level of complexity with the minimum number of components. In order to comply with this law, we must manage the world differently than before. The land management factor is placed within the framework of this concept. The aim of this study is to make a comparative analysis of land management in the studied regions, taking into account its impact on the competitive advantages of agriculture. Increasing competition for the use of land for non-food purposes, in light of a dynamic increase in about 30% of the population on the planet by 2050, will force more intensive use of this factor, which could inevitably lead to environmental degradation and lack of food. With an increase in the number of people on the planet the chances of achieving a competitive advantage by regions with higher agricultural area per capita will increase thanks to exports of food. This indicates the consistency of global interest with the regional one. The study included five provinces, i.e: Lublin, Subcarpathian, Podlaskie, Świętokrzyskie and Warmian-Masurian. They form the Polish area of Eastern Europe. Directions of use of the geographic area of the country as well as the use of land were established by comparing the results obtained in agriculture in 2005 and 2011, and exceptionally in 2012. The method which was used within the study was the tabulardescriptive method as well as horizontal and vertical analysis and valuation. The study shows that the use of the earth’s surface for food cultivation purpose is becoming less competitive than its use for non-food cultivation purposes.

description: In einem kleinen Lager im Tiefland bei Kitros (Makedonien) werden fluviale Bildungen durch kolluviale Sedimente und einige Meter Löß mit fossilen Böden überdeckt. Trotz der makro- und mikromorphologisch sehr ausgeprägten Böden werden die Deckschichten gemäß der allgemeinen Geländesituation, wie der Details im Profilaufbau in die Würmeiszeit gestellt. Die vier fossilen Böden sind weitgehend an Kalk verarmt, sie sind sehr tonreich und zeigen ausgesprochen verdichtetes Gefüge. Die typologische Ansprache als „rote Mediterranböden" kann vorerst allerdings nur eine Arbeitsbezeichnung sein. Der tiefste dieser Böden wird dem Zeitabschnitt Amersfoort- bis Broerup-Interstadial, der oberste dem Stillfried B zugeordnet. Gleichartige Vorkommen wurden außerdem bei Xanthi und in der nördlichen Türkei gefunden. Damit zeichnet sich eine eigenständige Löß- und Paläobodenprovinz ab. Feuchtere bzw. wechselfeuchtere Phasen werden darin durch die Böden angezeigt. Diese sind einem Ablauf zwischengeschaltet, der trockener war, der insbesondere — wie auch sonst — gegen das Hochglazial hin durch aridere Bedingungen bei erheblich abgesenkten Temperaturen ausgezeichnet war.

description: Social media has become an essential channel for posting disaster-related information, which provide governments and relief agencies real-time data for better disaster management. However, research in this field has not received sufficient attention and extracting useful information is still challenging. This paper aims to improve disaster relief efficiency via mining and analyzing social media data like public attitudes towards disaster response and public demands for targeted relief supplies during different types of disasters. We focus on different natural disasters based on properties such as types, durations, and damages, which contains a total of 41,993 tweets. In this paper, public perception is assessed qualitatively by manually classified tweets, which contain information like the demand for targeted relief supplies, satisfactions of disaster response, and public fear. Public attitudes to natural disasters are studied via a quantitative analysis using eight machine learning models. To better provide decision-makers with the appropriate model, the comparison of machine learning models based on computational time and prediction accuracy is conducted. The change of public opinion during different natural disasters and the evolution of people's behavior of using social media for disaster relief in the face of the identical type of natural disasters as Twitter continues to evolve are studied. The results in this paper demonstrate the feasibility and validation of the proposed research approach and provide relief agencies with insights into better disaster management.

description: Die glazialen Sedimente des Untersuchungsgebietes im zentralen Teil der dänischen Insel Fünen sind durch intensive Deformation geprägt. In den mächtigen glazifluviatilen Sedimentfolgen treten vor allem Überschiebungen, stark deformierte Faltenstrukturen und Zungenfalten auf. Da die Einmessung dieser Strukturen bis zu drei Deformationsrichtungen ergibt, müssen verschiedene Eisbewegungsrichtungen auf die Sedimente eingewirkt haben. Mit Hilfe sedimentologischer Untersuchungen des im Hangenden aufgeschlossenen Tills ist die Bildung eines großen Teils der Deformationsstrukturen mit dem Hauptvorstoß der Weichselzeit aus Nordosten und dem darauffolgenden jungbaltischen Vorstoß aus südöstlicher Richtung zu korrelieren. Die nahezu gleichmäßige Verteilung der verschiedenen Deformationsrichtungen lässt sich auf unterschiedliche Scherfestigkeiten der einzelnen Profilteile zurückführen, die z.T. eine Überprägung der bereits vorhandenen Deformationsstrukturen verhinderten. Es gibt keinen Zusammenhang zwischen der Eisvorstoßdynamik und bestimmten glazialtektonischen Strukturen, deren Stil vielmehr durch rheologische Eigenschaften des Sedimentes bestimmt ist. Die hohe Geschwindigkeit des jungbaltischen, als Eisstrom ausgebildeten Vorstoßes war z.T. durch Verformung des weichen, wasserübersättigten Untergrundes begünstigt.

The Andreev reflection at a clean Ferromagnet-Superconductor interface is incomplete, and Andreev channels with a large incidence angle are progressively suppressed with increasing exchange energy. As a result, the critical current exhibits oscillations as a function of the exchange energy and of the length of the ferromagnet and has a temperature dependence which deviates from the one predicted by the quasiclassical theory.

However, when the electrons are dressed by surface excitations (ripplons) to form polaron-like particles with sufficiently large effective mass, all the charge follows the straight path due to momentum conservation. This surface-wave induced transport is analogous to the motion of electrons coupled to surface acoustic waves in semiconductor 2DEGs.

description: Tracking agricultural expenditure in developing countries in Sub-Saharan Africa in a consistent and harmonised manner is important, not only in the context of the multilateral spending commitments made under the Comprehensive Africa Agriculture Development Programme, but also in order to gain a better understanding of the impact and efficacy of spending. In this paper, a method for identifying and aggregating spending items from a variety of sources is developed to better understand how agricultural spending has evolved in Malawi. The results show that the central government receives around 90% of agriculture allocations, and this is largely spent on fertiliser subsidies, leaving only limited funding for core strategic functions such as research, extension and irrigation. More generally, lessons learned from the Malawi analysis could potentially be applied in other country contexts with similar experiences in terms of the evolution of accounting systems or government structures.

Genese und Stratigraphie der ältesten Schotter der südlichen Iller-Lechplatte (Bayerisch-Schwaben)

description: Die ältesten Schotter der südlichen Iller-Lechplatte (Hochfirst, Stoffersberg, Plattenberg-Arlesrieder) haben pleistozänes Alter. Während ihrer Akkumulationsphase haben Ur-Iller und Ur-Lech über das gleiche Einzugsgebiet verfugt wie die Gletscher, deren umgelagerte Sedimente die donaueiszeitlichen und jüngeren Schotterkörper aufbauen. Daher ist anzunehmen, daß auch schon während der ältestpleistozänen Biberkaltzeiten im inneralpinen Raum Vereisungen existiert haben. Die Gletscher müssen dabei den heutigen morphologischen Alpenrand erreicht haben. Eine exakte Angabe der ehemaligen Eisrandlagen aus den Bibereiszeiten ist nicht möglich. Sie wären weit südlich der jüngeren donau-, günz-, mindel-, riß- und würmeiszeitlichen Moränen zu suchen und sind der glazialen, fluvioglazialen sowie periglazialen Erosion zum Opfer gefallen.

description: We describe a new means for electrically creating spin polarization in semiconductors. In contrast to spin injection of electrons by tunneling through a reverse-biased Schottky barrier, we observe spin accumulation at the metal/semiconductor interface of forward-biased ferromagnetic Schottky diodes, which is consistent with a theory of spin-dependent reflection off the interface. Spatiotemporal Kerr microscopy is used to image the electron spin and the resulting dynamic nuclear polarization that arises from the non equilibrium carrier polarization.

description: The absence of an agricultural census in Nigeria means that samples for surveys to estimate agricultural production are obtained from a non-comprehensive, non-representative set of farms. Therefore, aggregate production data quality is questioned. The methods employed herein provide a new way to empirically evaluate the quality of agricultural production estimates. Two objective types of data, namely the normalised difference vegetation index (NDVI), a satellite remote-sensing measure of intertemporal vegetation changes, and prices, which reveal supply-use dynamics, are used to analyse the degree to which agricultural production estimates reflect adjustments in growing/ market conditions. Broadly weak relationships were found between the production estimates and these objective measures, but with variations in degree across states. In addition, these two objective measures are more strongly related to each other than either is to production data. The results imply that the inclusion of NDVI and prices in agricultural production estimation models would improve the quality of the Nigerian production estimate.

description: Precursor gradients in a reaction-diffusion system are spatially varying coefficients in the reaction-kinetics. Such gradients have been used in various applications, such as the head formation in the Hydra, to model the effect of pre-patterns and to localize patterns in various spatial regions. For the 1-D Gierer-Meinhardt (GM) model we show that a simple precursor gradient in the decay rate of the activator can lead to the existence of stable, asymmetric, two-spike patterns, corresponding to localized peaks in the activator of different heights. This is a qualitatively new phenomena for the GM model, in that asymmetric spike patterns are all unstable in the absence of the precursor field. Through a determination of the global bifurcation diagram of two-spike steady-state patterns, we show that asymmetric patterns emerge from a supercritical symmetry-breaking bifurcation along the symmetric two-spike branch as a parameter in the precursor field is varied. Through a combined analytical-numerical approach we analyze the spectrum of the linearization of the GM model around the two-spike steady-state to establish that portions of the asymmetric solution branches are linearly stable. In this linear stability analysis a new class of vector-valued nonlocal eigenvalue problem (NLEP) is derived and analyzed.

Second-order gravitational effects of local inhomogeneities on CMB anisotropies and non-Gaussian signatures

description: Based on the second-order nonlinear theory of perturbations in non-zero Λflat cosmological models, we study the gravitational effects of local inhomogeneities on cosmic microwave background (CMB) anisotropies. As the local inhomogeneities we consider firstly large-scale dipole and quadruple distributions of galaxies around us and next an isolated cluster-scale matter distribution. It is found that, due to the second-order integral Sachs-Wolfe effect, the north-south asymmetry of CMB anisotropies and non-Gaussian signatures (in terms of scale-dependent estimators of kurtosis) in a spot-like object are caused from these matter distributions along light paths. Our theoretical results seem to be consistent with recent various observational results which have been shown by Hansen et al., Eriksen et al., Vielva et al. and Cruz et al.

description: Using count models, this paper assesses the intensity of land and water management practices among smallholder maize farmers in Ghana and the factors driving the number of practices adopted. Farmers’ use of fertiliser, non-burning of farmland and ploughing-in of vegetative cover are the practices adopted the most. The paper cautiously notes that the farmers who combine three of the land and water management practices have the highest average productivity. Access to extension contact, credit and farmers’ experiences of food shocks are important driving factors. The findings have implications for a comprehensive land and water management policy within which different strategies are articulated to increase the productivity of the farmers. Fertiliser application, no burning, zero tillage and ploughing-in of the vegetative cover are important. However, the regression results for maize yields suggest that the adoption of a high number of the technologies might not necessarily result in better yields.

description: We find a sharp combinatorial bound for the metric entropy of sets in R^n and general classes of functions. This solves two basic combinatorial conjectures on the empirical processes. 1. A class of functions satisfies the uniform Central Limit Theorem if the square root of its combinatorial dimension is integrable. 2. The uniform entropy is equivalent to the combinatorial dimension under minimal regularity. Our method also constructs a nicely bounded coordinate section of a symmetric convex body in R^n. In the operator theory, this essentially proves for all normed spaces the restricted invertibility principle of Bourgain and Tzafriri.

Formation of a Standing-Light Pulse through Collision of Gap Solitons

Subjects: subject: Pattern Formation and Solitons (nlin.PS)

description: Results of a systematic theoretical study of collisions between moving solitons in a fiber grating are presented. Various outcomes of the collision are identified, the most interesting one being merger of the solitons into a single zero-velocity pulse, which suggests a way to create pulses of ``standing light". The merger occurs with the solitons whose energy takes values between 0.15 and 0.35 of the limit value, while their velocity is limited by about 0.2 of the limit light velocity in the fiber. If the energy is larger, another noteworthy outcome is acceleration of the solitons as a result of the collision. In the case of mutual passage of the solitons, inelasticity of the collision is quantified by the energy-loss share. Past the soliton's stability limit, the collision results in strong deformation and subsequent destruction of the solitons. Simulations of multiple collisions of two solitons in a fiber-loop configuration are performed too. In this case, the maximum velocity admitting the merger increases to about 0.4 of the limit velocity. Influence of an attractive local defect on the collision is also studied, with a conclusion that the defect does not alter the overall picture, although it traps a small-amplitude pulse. Related effects in single-soliton dynamics are considered too, such as transformation of an input sech signal into a gap soliton (which is quantified by the share of lost energy), and the rate of decay of a quiescent gap soliton in a finite fiber grating, due to energy leakage through loose edges.
