description: Coal is a major resource in China both for chemicals production and power generation, but its impact on the environment demands attention. Solvent pretreatment is an effective method to realize cleaner utilization of coal. Shendong sub-bituminous coal was treated with three different deep eutectic solvents (DESs) – choline chloride (ChCl)-urea, ChCl-glycerol, and ChCl- ethylene glycol – at temperature as low as 120°C. Proximate/ultimate analyses, scanning electron microscopy, thermogravimetric analysis, and Fourier transform infrared spectroscopy were used to examine the physicochemical changes that occurred in coal after DESs treatment. Results showed that DES treatment led to coal fragmentation and decreased average particle size. Compared with raw coal (33.1%), DES-treated coal showed greater mass loss (35.2 − 37.7%), showing that the amount of low molecular mass species increased after treatment. This was confirmed by the observation that DES-treated coal had more volatile components and less minerals and functional groups that contained oxygen (especially C−O). The content of elemental sulfur also decreased from 0.26% to 0.10 − 0.15% after DES treatment, along with a reduction in aliphatic chain length and aromatic substitution degree, which were from 10.73 to 9.33−10.08 and 16.70% to 10.73−15.36%, respectively. The macromolecular structure of the coal was destroyed as a result of DES’s interactions with the weak covalent bonds and hydrogen bonds in the coal. These results suggest that DES has the potential to be used as a pretreatment solvent for coal conversion.

description: Industrial zones have been key drivers of growth across Asia but are also the source of water quality deterioration in surrounding rivers and streams. This study examined the effects of industrial zone located at the San Cristobal sub-catchment of Laguna de Bay, the Philippines on the spatiotemporal variation in water quality and benthic macroinvertebrate communities. Sampling sites were established in upstream and downstream sections of two tributaries of San Cristobal River, and the main channel of Diezmo River, and were sampled in 2018 during dry (February and April) and rainy (June and October) seasons. Results showed significant spatial difference with declining water quality (low dissolved oxygen; high levels of ammonia-nitrogen, phosphate-phosphorus, and total suspended solids) at the downstream sites. Consequently, benthic macroinvertebrates responded via change in community structure and composition (decline in pollution-sensitive taxa from upstream through downstream) to water quality degradation related to industrial land use downstream. Furthermore, seasonal variation was observed in benthic macroinvertebrate communities due to the absence of spate-induced disturbance, allowing benthic macroinvertebrates to proliferate in the rainy season. Findings of this study reveal that benthic macroinvertebrates can be used as bioindicators in the evaluation of the ecological integrity of surface river and stream systems that pass through industrial zones.

Constraining the Lifetime of QSOs with Present-day Mass Function of Supermassive Black Holes
Creators: name: Hosokawa, T.
Publisher: name: arXiv
Year: 2002
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Using the theoretical models of the QSO formation, we can reproduce optical QSO luminosity functions (LFs) at high redshifts (z > 2.2). Two different models can reproduce LFs successfully, though the lifetime of QSOs, t_Q, and the relation between the black hole mass and the host halo mass are different each other; t_Q = 10^6yr, in one model, t_Q > 10^7yr, in other models. Here, we propose a method to break this degeneracy. We calculate the mass function of supermassive black holes (SMBHs) at z=2.5, and compare the result with the current mass function obtained by Salucci et al.(1999). In the shorter lifetime model, the mass function at z=2.5 exceeds that of z=0.0 by one order of magnitude, then it should be ruled out. We conclude that the lifetime is at least t_Q > 10^7yr. Next, we examine the difference of the formation epoch of SMBHs existing at z=3.0 for each model under the model assumptions. We simply discuss the difference of formation epoch as another possible model-discriminator.

description: Evolutionary optimization is a generic population-based metaheuristic that can be adapted to solve a wide variety of optimization problems and has proven very effective for combinatorial optimization problems. However, the potential of this metaheuristic has not been utilized in Distributed Constraint Optimization Problems (DCOPs), a well-known class of combinatorial optimization problems prevalent in Multi-Agent Systems. In this paper, we present a novel population-based algorithm, Anytime Evolutionary DCOP (AED), that uses evolutionary optimization to solve DCOPs. In AED, the agents cooperatively construct an initial set of random solutions and gradually improve them through a new mechanism that considers an optimistic approximation of local benefits. Moreover, we present a new anytime update mechanism for AED that identifies the best among a distributed set of candidate solutions and notifies all the agents when a new best is found. In our theoretical analysis, we prove that AED is anytime. Finally, we present empirical results indicating AED outperforms the state-of-the-art DCOP algorithms in terms of solution quality.

description: The present work investigates clustering of a graph-based representation of industrial connections derived from international trade data by Hidalgo et al (2007) and confirms existence of around ten industrial clusters that are reasonably consistent with expected historical patterns of diffusion of innovation and technology. This supports the notion that technological development occurs in sequential innovation waves. The clustering method developed in this work follows conceptual ideas of Lambiotte and Barahona (2009), who suggested to use random walk to assess a hierarchical structure of network communities where different levels of the hierarchy correspond to different diffusion times. We, however, implement these ideas differently to match physics of the problem under consideration and introduce a hierarchal clustering procedure that is combined with convenient resorting of the elements. An equivalent spectral interpretation of the clustering is also given and discussed in the paper.

description: By solving the Bethe-Goldstone equation, we have obtained the $\bar{K}$ optical potential from the $\bar{K}N$ effective interaction in nuclear matter at T=0. We have extended the model by incorporating finite temperature effects in order to adapt our calculations to the experimental conditions in heavy-ion collisions. In the rank of densities ($0-2ρ_0$), the finite temperature $\bar{K}$ optical potential shows a smooth behaviour if we compare it to the T=0 outcome. Our model has also been applied to the study of the ratio between $K^+$ and $K^-$ produced at GSI with $T$ around 70 MeV. Our results point at the necessity of introducing an attractive $\bar{K}$ optical potential.

description: The Ga-Selati River is subjected to different forms of pollution from mining, industrial and agricultural activities, and human settlements. The objectives of the study were to assess heavy metal pollution and to determine possible sources of pollutants in the river. Water and sediment samples were collected and analysed for the following selected metals: arsenic (As), chromium (Cr), iron (Fe), manganese (Mn), nickel (Ni) and zinc (Zn) using sequential Inductively Coupled Plasma-optical emission spectrometry (ICP-OES). The enrichment factor (EF) and geo-accumulation index (Igeo) were used to determine the level of metal pollution in the sediment. The results indicated that Cr and Ni were the most accumulated elements in the sediments, and the midstream sites (S4 and S5) showed a much higher pollution level than the upstream and downstream sites. The main sources of pollutants were mining, wastewater/sewage and agricultural discharges. This may pose a serious threat to the river and health risk to the nearby rural communities, which rely on the river, especially for drinking water. Proper management strategies to reduce pollution is therefore necessary.

The interplay between migrants and natives as a determinant of migrants' assimilation: A coevolutionary approach
Creators: name: Bielawski, Jakub
name: Jakubek, Marcin
Publisher: name: arXiv
Year: 2019
Subjects: subject: Theoretical Economics (econ.TH)
subject: FOS: Economics and business

description: We study the migrants' assimilation, which we conceptualize as forming human capital productive on the labor market of a developed host country, and we link the observed frequent lack of assimilation with the relative deprivation that the migrants start to feel when they move in social space towards the natives. In turn, we presume that the native population is heterogenous and consists of high-skill and low-skill workers. The presence of assimilated migrants might shape the comparison group of the natives, influencing the relative deprivation of the low-skill workers and, in consequence, the choice to form human capital and become highly skilled. To analyse this interrelation between assimilation choices of migrants and skill formation of natives, we construct a coevolutionary model of the open-to-migration economy. Showing that the economy might end up in a non-assimilation equilibrium, we discuss welfare consequences of an assimilation policy funded from tax levied on the native population. We identify conditions under which such costly policy can bring the migrants to assimilation and at the same time increase the welfare of the natives, even though the incomes of the former take a beating.

description: We study the effect of an applied magnetic field on the nonequilibrium transport properties of a general cubic quantum network described by a tight-binding Hamiltonian with specially designed couplings to the leads that preserve open-system symmetries. We demonstrate that the symmetry of open systems can be manipulated by the direction of the magnetic field. Starting with all the symmetries preserved in absence of a field, the anisotropic and isotropic fields systematically break the symmetries, influencing all nonequilibrium properties. For simple cubic systems, we are able to identify the steady states that comprise of pure states, bath-dependent states (nonequilibrium steady states), and also nonphysical states. As an application, we show numerically for large cubic networks that the symmetry breaking can control nonequilibrium currents and that different environmental interactions can lead to novel features which can be engineered in artificial super-lattices and cold atoms.

description: In a software project, esp. in open-source, a contribution is a valuable piece of work made to the project: writing code, reporting bugs, translating, improving documentation, creating graphics, etc. We are now at the beginning of an exciting era where software bots will make contributions that are of similar nature than those by humans. Dry contributions, with no explanation, are often ignored or rejected, because the contribution is not understandable per se, because they are not put into a larger context, because they are not grounded on idioms shared by the core community of developers. We have been operating a program repair bot called Repairnator for 2 years and noticed the problem of "dry patches": a patch that does not say which bug it fixes, or that does not explain the effects of the patch on the system. We envision program repair systems that produce an "explainable bug fix": an integrated package of at least 1) a patch, 2) its explanation in natural or controlled language, and 3) a highlight of the behavioral difference with examples. In this paper, we generalize and suggest that software bot contributions must explainable, that they must be put into the context of the global software development conversation.

Identification of constitutive parameters from full thermal and kinematic fields: application to hyperelasticity
Creators: name: Charlès, S.

Publisher: name: arXiv
Year: 2019
Subjects: subject: Classical Physics (physics.class-ph)
subject: FOS: Physical sciences

description: In this paper, a new inverse identification method is developed from full kinematic and thermal field measurements. It consists in reconstructing the heat source from two approaches, a first one that requires the measurement of the temperature field and the value of the thermophysical parameters, and a second one based on the measurement of the kinematics field and a thermo-hyperelastic model that contains the parameters to be identified. The identification does not require any boundary conditions since it is carried out at the local scale. In the present work, the method is applied to the identification of hyperelastic parameters from a heterogeneous heat source field. Due to large deformation undergone by the rubber specimen tested, a motion compensation technique is developed to plot the kinematic and thermal fields at the same points before reconstructing the heat source.

description: The one particle quantum mechanics is considered in the frame of a N-body classical kinetics in the phase space. Within this framework, the scenario of a subquantum structure for the quantum particle, emerges naturally, providing an ontological support to the orthodox quantum mechanics. This approach to quantum mechanics, constitutes a deductive and direct method which, in a self-consistent scheme of a classical kinetics, allows us: i) to obtain the probabilistic nature of the quantum description and to interpret the wave function $ψ$ according to the Copenhagen school; ii) to derive the quantum potential and then the Schrödinger equation; iii) to calculate the values of the physical observables as mean values of the associated quantum operators; iv) to obtain the Heisenberg uncertainty principle.

description: We use a novel modeling framework that incorporates free entry into the R&D sector and uncertainty about technological opportunity to evaluate three policy regimes (relative to laissez faire) designed to address a market with negative environmental externalities: a carbon tax, an R&D subsidy, and a mix of the two instruments. We show carbon taxes on their own are sufficient to obtain most of the welfare gains achieved by an optimal policy mix, and that the optimal carbon tax level is relatively robust to changing modeling assumptions, in contrast to optimal R&D subsidies. We also show R&D subsidies tend to produce more disperse outcomes than a carbon tax: either more R&D entrants (when technological opportunity is favorable) or none at all (when technological opportunity is unfavorable).

description: Imagine a scenario in which the dark energy forms via the condensation of dark matter at some low redshift. The Compton wavelength therefore changes from small to very large at the transition, unlike quintessence or metamorphosis. We study CMB, large scale structure, supernova and radio galaxy constraints on condensation by performing a 4 parameter likelihood analysis over the Hubble constant and the three parameters associated with Q, the condensate field: Omega_Q, w_f and z_t (energy density and equation of state today, and redshift of transition). Condensation roughly interpolates between Lambda CDM (for large z_t) and sCDM (low z_t) and provides a slightly better fit to the data than Lambda CDM. We confirm that there is no degeneracy in the CMB between H and z_t and discuss the implications of late-time transitions for the Lyman-alpha forest. Finally we discuss the nonlinear phase of both condensation and metamorphosis, which is much more interesting than in standard quintessence models.

description: The objective of the present paper is to identify the determinants of the form of collaboration initiated between an upstream innovator and a downstream producer in order to incorporate a new input and commercialize an innovation consisting of a quality enhanced final product, with an empirical application to the GM plant industry. The choice of upstream firm between license, joint venture, merger or a subsidiary is modeled as a function of three parameters: degree of quality improvement engendered by the new input, the market share of the downstream producer and the capability of the downstream producer to incorporate the new input and commercialize it successfully. We also discuss the case where the downstream firm is a cooperative.

description: Because the Impact Factor (IF) is an average quantity and most journals are small, IFs are volatile. We study how a single paper affects the IF using data from 11639 journals in the 2017 Journal Citation Reports. We define as volatility the IF gain (or loss) caused by a single paper, and this is inversely proportional to journal size. We find high volatilities for hundreds of journals annually due to their top-cited paper: whether it is a highly-cited paper in a small journal, or a moderately (or even low) cited paper in a small and low-cited journal. For example, 1218 journals had their most cited paper boost their IF by more than 20%, while for 231 journals the boost exceeded 50%. We find that small journals are rewarded much more than large journals for publishing a highly-cited paper, and are also penalized more for publishing a low-cited paper, especially if they have a high IF. This produces a strong incentive for prestigious, high-IF journals to stay small, to remain competitive in IF rankings. We discuss the implications for breakthrough papers to appear in prestigious journals. We also question the practice of ranking journals by IF given this uneven reward mechanism.

description: We examine 3 analytic theories of magnetospheric accretion onto classical T Tauri stars under the assumption that the magnetic field strength does not vary appreciably from star to star. From these investigations we derive predicted relationships among the stellar mass, radius, rotation period, and disk accretion rate. Data from 5 studies of the accretion parameters of CTTSs are used to test the predicted correlations. We generally find that the data do not display the predicted correlations except for that predicted by the model of Shu et al. as detailed by Ostriker and Shu and extended here to include non-dipole field topologies. Their identification of the trapped flux as an important quantity in the model appears to be critical for reconciling the observed data to the theory. While the data do generally support the extended Ostriker and Shu predictions, only one of the two studies for which the requisite data exist show the highest correlation when considering all the relevant parameters. This suggests great care must be taken when trying to use existing observations to test the theory.

description: The generation and distribution of entanglement are key resources in quantum repeater schemes. Temporally multiplexed systems offer time-bin encoding of quantum information which provides robustness against decoherence in fibers, crucial in long distance communication. Here we demonstrate the direct generation of entanglement in time between a photon and a collective spin excitation in a rare earth ion doped ensemble. We analyze the entanglement by mapping the atomic excitation onto a photonic qubit and by using time-bin qubits analyzers implemented with another doped crystal using the atomic frequency comb technique. Our results provide a solid-state source of entangled photons with embedded quantum memory. Moreover, the quality of the entanglement is high enough to enable a violation of a Bell inequality by more than two standard deviations.

description: This article discusses the impact on power con-sumption of five dedicated structures of Radix-2 Decimation inTime (DIT) butterflies, when synthesized in different technologies.The five different structures are compared using both addercompressors and the addition operator of the tool. Power, areaand cells count results for 45nm are presented and comparedto the results from the literature that used 180nm technology.The study of different butterfly structures that compose FFTarchitecture, along with analysis of different logic synthesistechnologies allow significant results that can contribute to thereduction in power and area of this implementation. In thiswork different structures dedicated to the Radix-2 DIT butterflywith two pipeline stages for 16 bit-width running at 100MHzare synthesized in 45nm in order to compare results with theliterature. For the logic synthesis of the implemented butterfliesCadence Encounter (R) RTL Compiler v08.1 with NanGate OpenCell Library 45nm was used. The synthesis results show thecell count, area and power consumption for the synthesizedbutterflies. Regarding power consumption, switching activityanalysis is performed using 10.000 input vectors at inputs ofthe butterflies. Results shows that the use of adder compressorsare competitive in power consumption and area.

description: A simplified 1D (one-dimensional) model for a generalized 3N system is considered, as a testing ground for the explicit treatment of the meson dynamics in this system. We focus attention on the irreducible diagrams generated by the pion dynamics in the 3N system, and in particular to a new type of three-nucleon force discussed recently in the literature, and generated by the one-pion-exchange mechanism in presence of a nucleon-nucleon correlation. It is found that these new terms in the simplified model have an approximately 30% effect compared to the standard three-nucleon force terms in a `Triton' binding energy calculation. It is suggested that this effect should also not be ignored in realistic calculations.

description: As the regulation of carbon dioxide emissions play an increasingly important role in fighting against global warming, tracking carbon dioxide emissions trends, estimating the determinants of driving emissions, and identifying opportunities for reducing emissions will be necessary. This paper studies the relationship among carbon dioxide emissions, energy consumption and economic growth in United States at state level during the period from 1960 to 2011. It is essential to study state level determinants of carbon dioxide emissions especially for a country that differs from coast to coast in energy use, economic development strategy, and carbon dioxide reduction policy. Based on the EKC long run analysis of CO2 emissions in each state of US, we found that 13 states show inverted-U relationship between CO2 emissions and economic development, 18 states display N relationship, 6 states indicate increasing linear relationship, 6 states appear decreasing linear relationship, and the rest states show no cointegration among the variables. We also found that energy consumption always having significant and positive effect on carbon dioxide emissions. States in US have already tried a variety of strategies to reduce emission over the past decades, vary by state results of estimated EKC relationship may help indicate the past successes and failures of efforts, and provide guidance for future environmental policy.
Could thermal fluctuations seed cosmic structure?

description: We examine the possibility that thermal, rather than quantum, fluctuations are responsible for seeding the structure of our universe. We find that while the thermalization condition leads to nearly Gaussian statistics, a Harrisson-Zeldovich spectrum for the primordial fluctuations can only be achieved in very special circumstances. These depend on whether the universe gets hotter or colder in time, while the modes are leaving the horizon. In the latter case we find a no-go theorem which can only be avoided if the fundamental degrees of freedom are not particle-like, such as in string gases near the Hagedorn phase transition. The former case is less forbidding, and we suggest two potentially successful ``warming universe'' scenarios. One makes use of the Phoenix universe, the other of ``phantom'' matter.

description: Cloudberry (Rubus chamaemorus L.) is a plant rich in various biologically active compounds. In this work, the composition and concentrations of pentacyclic triterpenoids (PCTs) and phytosterols in various parts of cloudberries were studied using high-performance liquid chromatography–tandem mass spectrometry by multiple reaction monitoring mode (MRM, targeted analysis) and precursor ion scan mode (non-targeted analysis and semi-quantitative determination). Moderately polar fractions of cloudberry leaves, sepals and berries extracts are rich in β-sitosterol glycoside and various triterpenoid acids, among which tormentic acid (∼190–1800 μg/g dw part of cloudberries) and its hydroxyl derivatives (∼3.1–470 μg/g dw part of cloudberries) predominate. Non-polar fractions are characterised by the presence of amyrins (0.76–110 μg/g dw part of cloudberries), β-sitosterol (62–750 µg/g dw part of cloudberries) and β-sitosterol glycoside (∼92–360 μg/g dw sepals).
Deeply bound pionic atoms from the $(γ,p)$ reaction in nuclei

description: We study the $(γ,p)$ reaction on $^{208}Pb$ leading to $^{207}Pb$ with a bound pion attached to it in the lowest 1s or 2p pionic levels. The reaction can be made recoilless to optimize the production cross section but we must choose a bit higher photon energy to overcome the Coulomb barrier in the proton emission. The cross sections obtained are easily measurable and can be larger than 50 per cent of the background from inclusive ($γ$,p). This makes it a clear case for the detection of the pionic atom signals, converting this reaction into a practical tool to produce deeply bound pionic atoms.
