machine-actionable metadta

description: We will introduce an approach to developing machine-actionable metadata templates. Also, we will present the Generic Dataset Metadata Template (GDMT) as an example of a configurable machine-actionable template. Furthermore, we will show how to configure this template to be domain-specific by means of introducing domain-specific vocabularies.

description: Generating quantum entanglement in large systems on time scales much shorter than the coherence time is key to powerful quantum simulation and computation. Trapped ions are among the most accurately controlled and best isolated quantum systems with low-error entanglement gates operated via the vibrational motion of a few-ion crystal within tens of microseconds. To exceed the level of complexity tractable by classical computers the main challenge is to realise fast entanglement operations in large ion crystals. The strong dipole-dipole interactions in polar molecule and Rydberg atom systems allow much faster entangling gates, yet stable state-independent confinement comparable with trapped ions needs to be demonstrated in these systems. Here, we combine the benefits of these approaches: we report a $700\,\mathrm{ns}$ two-ion entangling gate which utilises the strong dipolar interaction between trapped Rydberg ions and produce a Bell state with $78\%$ fidelity. The sources of gate error are identified and a total error below $0.2\%$ is predicted for experimentally-achievable parameters. Furthermore, we predict that residual coupling to motional modes contributes $\sim 10^{-4}$ gate error in a large ion crystal of 100 ions. This provides a new avenue to significantly speed up and scale up trapped ion quantum computers and simulators.

description: Recent model-based congestion control algorithms such as BBR use repeated measurements at the endpoint to build a model of the network connection and use it to achieve optimal throughput with low queuing delay. Conversely, applying this model-based approach to Active Queue Management (AQM) has so far received less attention. We propose the new AQM scheduler cocoa based on fair queuing, which adapts the buffer size depending on the needs of each flow without requiring active participation from the endpoint. We implement this scheduler for the Linux kernel and show that it interacts well with the most common congestion control algorithms and can significantly increase throughput compared to fair CoDel while avoiding overbuffering.

description: We present results of a CO(1-0) line survey in a complete sample of 12 low redshift (Z < 0.1), optically bright QSOs (PG QSOs with M_B < -23 mag). Six new CO detections are reported here at levels exceeding I_CO ~2 Jy km/s. Combined with three previously reported detections, we find that 9 of the 12 QSOs have abundant, dense ISMs characteristic of late type galaxies. In all 9 of the detected QSOs, the derived molecular gas masses are M(H2) > 1.0e9 M_solar, with the most massive being 1e10 M_solar ~(PG 0050+124 -- I Zw 1). In the three sources not yet detected in CO, the upper limits on the gas masses are ~ 1e9 M_solar and thus we cannot rule out abundant ISMs even in these objects. Since our sample was chosen entirely on the basis of low redshift and optical luminosity (and not selected for strong infrared emission), we conclude that the majority of luminous, low redshift QSOs have gas-rich host galaxies and therefore can not be normal elliptical galaxies.

Mergers and Market Power in the US Nitrogen Fertilizer Industry

description: Nitrogenous fertilizer prices spiked in early 2010 despite the fact that natural gas prices, nitrogen fertilizer’s main production cost, have dramatically fallen during this time period. We hypothesize that a merger which occurred between CF and Terra industries in 2010 exacerbated market power in an already concentrated industry, causing nitrogen fertilizer prices to increase. To test this hypothesis, we propose a structural vector autoregressive (SVAR) model. By including corn futures, natural gas and nitrogen fertilizer prices within an SVAR model we control for demand and supply shocks which affect the nitrogen fertilizer market. The remaining variation in fertilizer prices at 2010 not explained by the model is attributed to the merger. If we set this residual to zero, we can then use the SVAR model to forecast a counterfactual fertilizer price series which represents the price of nitrogen fertilizer in the absencebsence of the merger. Applying this technique to the data suggests that the merger raised prices by roughly 75%. This approach presents a middle-ground between the current methodologies used in the retrospective merger analysis literature. It is more transparent than structural approaches such as Nevo (2000) which make strong assumptions on demand and market conduct. Conversely, this time series approach is more applicable than the reduced form approaches such as Hastings (2004) that employ a difference in difference method and consequently rely on the existence of a credible control group.

description: We calculate magnon dispersions and damping in the Kitaev-Heisenberg model with an off-diagonal exchange $Γ$ and isotropic third-nearest-neighbor interaction $J_3$ on a honeycomb lattice. This model is relevant to a description of the magnetic properties of iridium oxides $α$-Li$_2$IrO$_3$ and Na$_2$IrO$_3$, and Ru-based materials such as $α$-RuCl$_3$. We use an unconventional parametrization of the spin-wave expansion, in which each Holstein-Primakoff boson is represented by two conjugate hermitian operators. This approach gives us an advantage over the conventional one in identifying parameter regimes where calculations can be performed analytically. Focusing on the parameter regime with the zigzag spin pattern in the ground state that is consistent with experiments, we demonstrate that one such region is $Γ= K>0$, where $K$ is the Kitaev coupling. Within our approach we are able to obtain explicit analytical expressions for magnon energies and eigenstates and go beyond the standard linear spin-wave theory approximation by calculating magnon damping and demonstrating its role in the dynamical structure factor. We show that the magnon damping effects in both Born and self-consistent approximations are very significant, underscoring the importance of non-linear magnon coupling in interpreting broad features in the neutron-scattering spectra.

Solving a Special Case of the Intensional vs Extensional Conjecture in Probabilistic Databases
Creators: name: Monet, Mikaël
Publisher: name: arXiv
Year: 2019
Subjects: subject: Databases (cs.DB)
subject: FOS: Computer and information sciences

description: We consider the problem of exact probabilistic inference for Union of Conjunctive Queries (UCQs) on tuple-independent databases. For this problem, two approaches currently coexist. In the extensional method, query evaluation is performed by exploiting the structure of the query, and relies heavily on the use of the inclusion-exclusion principle. In the intensional method, one first builds a representation of the lineage of the query in a tractable formalism of knowledge compilation. The chosen formalism should then ensure that the probability can be efficiently computed using simple disjointness and independence assumptions, without the need of performing inclusion-exclusion. The extensional approach has long been thought to be strictly more powerful than the intensional approach, the reason being that for some queries, the use of inclusion-exclusion seemed unavoidable. In this paper we introduce a new technique to construct lineage representations as deterministic decomposable circuits in polynomial time. We prove that this technique applies to a class of UCQs that had been conjectured to separate the complexity of the two approaches. In essence, we show that relying on the inclusion-exclusion formula can be avoided by using negation. This result brings back hope to prove that the intensional approach can handle all tractable UCQs.

description: Controlled vocabularies are one of the most essential components in achieving machine-actionability and (meta)data linking.

Since often existing controlled vocabularies aren’t sufficient to cover the needs of particular domains, we will learn how to build them.
Activity time series of old stars from late F to early K IV. Diagnosis from photometry

description: High-precision time series have recently become available for many stars as a result of data from CoRoT, Kepler, and TESS and have been widely used to study stellar activity. They provide information integrated over the stellar disk, hence many degeneracies between spots and plages or sizes and contrasts. Our aim is to understand how to relate photometric variability to physical parameters in order to help the interpretation of these observations. We computed a large number of synthetic time series of brightness variations for old MS stars within the F6-K4 range, using consistent modeling for radial velocity, astrometry, and LogR'HK. We analyzed these time series to study the effect of the star spectral type on brightness variability, the relationship between brightness variability and LogR'HK, the interpretation of brightness variability as a function of spot and plage properties, and the spot-dominated or plage-dominated regimes. Within our range of activity levels, the brightness variability increases toward low-mass stars, as suggested by Kepler results. Brightness variability roughly correlates to LogR'HK level, but with a large dispersion, caused by spot contrast and inclination. It is also directly related to the number of structures, and we show that it cannot be interpreted solely in terms of spot sizes. In the activity range of old main-sequence stars, we can obtain both spot or plage dominated regimes, as in observation. The same star can be observed in both regimes depending on inclination. Only strong correlations between LogR'HK and brightness variability are significant. Our realistic time series proves to be extremely useful when interpreting observations and understanding their limitations, most notably in terms of activity interpretation. Inclination is crucial and affects many properties, such as amplitudes and the respective role of spots and plages.

Nonequilibrium Phase Transition for a Heavy Particle in a Granular Fluid

Year: 2001
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: It is shown that the homogeneous cooling state (HCS) for a heavy impurity particle in a granular fluid supports two distinct phases. The order parameter $ϕ$ is the mean square velocity of the impurity particle relative to that of a fluid particle, and the control parameter $ξ$ is the fluid cooling rate relative to the impurity collision rate. For $ξ<1$ there is a ``normal'' phase for which $ϕ$ scales as the fluid/impurity mass ratio, just as for a system with elastic collisions. For $ξ>1$ an ``ordered'' phase occurs in which $ϕ$ is finite even for vanishingly small mass ratio, representing an extreme violation of energy equipartition. The phenomenon can be described in terms of a Landau-like free energy for a second order phase transition. The dynamics leading to the HCS is studied in detail using an asymptotic analysis of the Enskog-Lorentz kinetic equation near each phase and the critical domain. Critical slowing is observed with a divergent relaxation time at the critical point. The stationary velocity distributions are determined in each case, showing a crossover from Maxwellian in the normal phase to an exponential quartic function of the velocity that is sharply peaked about the non-zero $ϕ$ for the ordered phase. It is shown that the diffusion coefficient in the normal phase diverges at the critical point and remains so in the ordered phase. This is interpreted as a transition from diffusive to ballistic dynamics between the normal and ordered phases.

description: The objective of this study is to explore the possibilities of improving production and income on small farms through better allocation of resources. It pertains to the area that represents the low potential cereal crops zone (LPCZ) of Ethiopian highlands in the Shoa region. The basic primary data were drawn from 50 randomly selected farms in the area, and secondary data were obtained from ILCA. LP and MOTAD are used as analytical tools. The results of the study indicates a substantial potential for increasing net farm cash incomes by efficient allocation of available resources under current level of technology. The study further revealed that small-scale farmers in the study area operate at a relatively higher risk under the existing situation than would be the case under an-optimal situation. Thus, small-scale farmers should allocate resources optimally not only to increase cash income but also to reduce risk.

description: Mutual learning process between two parity feed-forward networks with discrete and continuous weights is studied analytically, and we find that the number of steps required to achieve full synchronization between the two networks in the case of discrete weights is finite. The synchronization process is shown to be non-self-averaging and the analytical solution is based on random auxiliary variables. The learning time of an attacker that is trying to imitate one of the networks is examined analytically and is found to be much longer than the synchronization time. Analytical results are found to be in agreement with simulations.

description: We explore the viability of laboratory-scale mechanical resonators as detectors for ultralight scalar dark matter. The signal we investigate is an atomic strain due to modulation of the fine structure constant and the lepton mass at the Compton frequency of dark matter particles. The resulting stress can drive an elastic body with acoustic breathing modes, producing displacements that are accessible with opto- or electromechanical readout techniques. To address the unknown mass of dark matter particles (which determines their Compton frequency), we consider various resonator designs operating at kHz to MHz frequencies, corresponding to $10^{-12}-10^{-5}$ eV particle mass. Current resonant-mass gravitational wave detectors that have been repurposed as dark matter detectors weigh $\sim \! 10^3$ kg. We find that a large unexplored parameter space can be accessed with ultra-high-$Q$, cryogenically-cooled, cm-scale mechanical resonators possessing $\sim \! 10^7$ times smaller mass.

description: Using the Ginzburg-Landau theory in very general terms, we develop a simple scaling procedure which allows to establish the temperature dependence of the upper critical field and the value of the superconducting critical temperature Tc of type-II superconductors from measurements of the reversible isothermal magnetization. An analysis of existing experimental data shows that the normalized dependencies the upper critical field on T/Tc are practically identical for all families of high temperature superconductors at all temperatures for which the magnetization data are available.

Farm Management

description: In dryland agricultural systems, efficient farm management requires a degree of flexibility according to variations in climate from year to year. Tactical adjustments to the mix of farm enterprises can capitalize on good growing conditions and minimise losses under poor growing conditions. In this paper, a discrete stochastic programming model of dryland wheat-sheep farms in Western Australia is used to identify optimal tactical adjustments to climate and to calculate the value of these tactical adjustments. The model, MUDAS, includes nine discrete season types with a wide range of options for tactical adjustments in each. In the standard model, optimal tactical responses increase expected net cash surplus by approximately 22% relative to a fixed or inflexible strategy. In most season types, changes to the long term farm strategy are made on less than 10% of the farm area, although in some seasons over 25% of the farm can require adjustments to the enterprise selected. The benefits of flexibility are not evenly distributed across different season types but occur predominantly in the best and worst seasons. The magnitude of benefits is affected differently by different commodity prices. Benefits of flexibility are due to capitalizing on knowledge about the greater volatility of profits from cropping than from livestock production. Deterministic models and even stochastic models which don't include activities for tactical adjustments miss this key feature of the system.

description: Present studies were conducted to isolate and identify the seed-borne pathogenic fungus from the selected tomato variety through morphological and molecular techniques based on the sequencing of internal transcribed spacer (ITS) region of 18S rDNA. According to the colony and conidial features, the fungus was identified as Curvularia sp. The obtained ITS sequencing showed above 99% similarity with Curvularia lunata in the NCBI database. The sequence of the fungus was deposited in NCBI GenBank under the accession number: ITS, MH382879.1. Besides, the phylogenetic tree further confirmed the taxonomic position of the studied fungus. Growth characteristics of the fungus on nine different fungal culture media were evaluated, in which Honey peptone agar, Carrot agar, Potato sucrose agar, and Kauffman’s agar were found the most suitable. The maximum vegetative growth of the fungus was recorded at 30°C temperature and pH conditions. The bio-control potential of five different antagonists against the studied fungus was assessed, in which Trichoderma harzianum showed the better performance to restrict mycelial growth. Three ethanolic plant extracts were also evaluated, in which Lowsonia inermis L. exhibited above 60% mycelial growth inhibition of the fungus. Among three tested fungicides, Tilt 250 EC was found as an excellent fungicide to inhibit mycelial growth of C. lunata under in vitro conditions.

description: Decisions about food choices in terms of products, preparation, and venue are technology choices in the context of the household production function where consumers consider benefits from taste, health, convenience, and budget given different technologies and information. The literature on adoption in economics and marketing as well as the literature on information sources in food decision-making provides a context to assess the impact of new information and new media on food choices. This literature suggests that consumers use media for identifying information relevant to their decisions, but make final assessments based on total benefits and the probability of fit of a product in meeting their needs. Consumers rely on both formal and informal sources of information in making different choices, and electronic social networks improve the quality of and help more effectively target information from formal sources, but especially information from informal sources. Informational networks expand access of visual information to consumers when making food choices, and allow real-time interaction among consumers that enables them to be more informed about these decisions. Finally, food providers will recognize the role of electronic social networks and new media in food choices, and thus may use them to influence consumers’ food selection.

description: Our modern day Solar System has $4.6\times10^9$ yrs of evolution behind it with just a few relics of its birth conditions remaining. Comets are thought to be some of the most pristine tracers of the initial ingredients that were combined to produce the Earth and the other planets. Other low-mass protostars may be analogous to our proto-Sun and hence, could be used to study the building blocks necessary to form Solar-like systems. This study tests this idea on the basis of new high sensitivity, high spatial resolution ALMA data on the protoplanetary disc-scales (~70 au) of IRAS 16293-2422 and the bulk composition of comet 67P/Churyumov-Gerasimenko, as determined for the first time with the unique in situ monitoring carried out by Rosetta. The comparative analysis of the observations from the Protostellar Interferometric Line Survey (PILS) and the measurements made with Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) shows that the relative abundances of CHO-, N-, and S-bearing molecules correlate, with some scatter, between protostellar and cometary data. A tentative correlation is seen for the first time for P- and Cl-bearing compounds. The results imply that the volatile composition of cometesimals and planetesimals is partially inherited from the pre- and protostellar phases of evolution.

description: A growing body of work has established the modelling of stochastic processes as a promising area of application for quantum techologies; it has been shown that quantum models are able to replicate the future statistics of a stochastic process whilst retaining less information about the past than any classical model must -- even for a purely classical process. Such memory-efficient models open a potential future route to study complex systems in greater detail than ever before, and suggest profound consequences for our notions of structure in their dynamics. Yet, to date methods for constructing these quantum models are based on having a prior knowledge of the optimal classical model. Here, we introduce a protocol for blind inference of the memory structure of quantum models -- tailored to take advantage of quantum features -- direct from time-series data, in the process highlighting the robustness of their structure to noise. This in turn provides a way to construct memory-efficient quantum models of stochastic processes whilst circumventing certain drawbacks that manifest solely as a result of classical information processing in classical inference protocols.

Theoretical calculations of the effective mass depending on band filling are also given by Gutzwiller's variational calculations. On the basis of the concept of measurement, the effective mass is an average of the true effective mass in the Brinkman-Rice(BR) picture for metal phase and is the effect of measurement. The true correlation strength (U/U_c=k_{BR}) in the BR picture is evaluated as 0.92

description: In a previous paper, one of us calculated iron K$α$ line profiles emitted from possible accretion disks around traversable wormholes as a first step to use X-ray reflection spectroscopy to search for astrophysical wormholes in active galactic nuclei. In the present paper, we extend that work and construct an XSPEC model for the whole relativistic reflection spectrum. We apply our model to XMM-Newton and NuSTAR observations of the supermassive object in MCG-6-30-15 and we check whether these observations prefer the hypothesis that the central body is a Kerr black hole or a traversable wormhole. We find that the two models provide equally good fits, so with the available data we cannot distinguish the black hole and wormhole scenarios.

description: The Common Agricultural Policy (CAP) is the most important EU Policy in terms of total expenditure. Nevertheless, its impact on EU-27 regions is rather uneven: actually, some regions have historically received a larger support than others. Territorial imbalances, however, represent only part of the story. The CAP comprises a wide range of agricultural and rural measures, from agricultural market interventions to agro-environmental payments and rural development measures. Due to their underlying objectives, expenditures from different CAP Pillars are allocated according to different territorial patterns at local level. In this paper, CAP real expenditures for years 2007-2011 are analysed at EU-27 NUTS 3 level, by considering expenditure intensity per hectare of utilised agricultural area (UAA). Several CAP expenditure typologies (Direct Payments, Market Intervention Measures and RDP’s Axes, i.e., Axis 1, Axis 2 and Axis 3) are considered. Their spatial allocation highlights different territorial patterns and suggests the existence of well defined spatial clusters. They seem to be determined by the nature of CAP itself. Indeed, despite being a single EU policy, the heterogeneous nature of its measures and their spatial allocation make the CAP a combination of several territorial policies.

description: In this paper the level of taxation of Italian farm households is studied by analyzing the data of agricultural households in the Italian EU-SILC database. The proposed approach allows to use the EU- SILC database to fill missing information on FADN database through a methodology of statistical matching. The work provides some indications on the level of tax burden and on some factors affecting it as well as on the degree of progressivity of the taxation of agricultural incomes. The results suggest that the level of tax burden is not very much affected by the amount of income actually produced. Indeed, the taxation of agricultural incomes seems paradoxically to have a regressive effect favouring farm families in which farming accounts for the large part of family income.

description: In this paper we assess the impact of the LD 114/1998 on the structure of the Italian food retailing industry. We use difference–in–difference technique, comparing the level of concentration, number of stores, average store size and level of service offered to consumers in regions enacting mandated consistent with the LD 114/1998, versus those that did not. Results show that, once the endogenous nature of policy changes is controlled for, the policy appears more effective than expected, in terms of its impact on concentration, consumers’ access, store size and level of service to consumers. While the decree overall seems to have help the consumer to have more access and more in-store services, our analysis suggests food retailing became more concentrated in response to the implementation of the LD 114/1998. Further, the effect of the liberalization seems to have stronger effects in regions where the level of liberalization implemented is “low”.
