description: A variety of contracts between wineries and grape growers are observed in Brazil. This study addresses the concept of coordination of food chains, particularly the stability of contractual relationships. A qualitative analysis of industry-farmers contracts is presented, followed by a quantitative analysis testing transaction cost economics-based hypothesis. Scale, location, age of vineyard, and the cooperative organizational form are addressed in terms of the effect on the stability of contracts. Vertical and horizontal coordination are addressed. Data come from a sample of 139 grape-growers that supplied 10 major wineries. The results show that more stable contracts or vertical integration are characteristic of high quality wine production, where the need for strict contractual coordination is more relevant, i.e. risk of hold up losses is larger. We test the hypothesis that site specificity and quality-related specific investments are associated with more stable contractual architectures. Farmers' cooperatives present poorer performance but tend to hold more stable relationships with their members, possibly the result of adverse selection, since specialized farmers prefer to maintain contracts with investor-owned wineries, instead of farmers' cooperatives. Conclusions are presented in the final part.

description: Technology and society share a close relationship, as the adoption of new technologies has consequences across value systems and institutions in society. Historically, the emergence of agriculture and subsequent technologies played an important role in shaping social relations. This paper examines the Green Revolution that took place in India during the late 1960s and 70s from the perspectives offered by different development paradigms of technical change in developing countries. The high yielding variety seeds of wheat and rice that were then introduced significantly enhanced domestic food production, which was far from adequate after independence...

description: A protocol for quantum secure direct communication using blocks of EPR pairs is proposed. A set of ordered $N$ EPR pairs is used as a data block for sending secret message directly. The ordered $N$ EPR set is divided into two particle sequences, a checking sequence and a message-coding sequence. After transmitting the checking sequence, the two parties of communication check eavesdropping by measuring a fraction of particles randomly chosen, with random choice of two sets of measuring bases. After insuring the security of the quantum channel, the sender, Alice encodes the secret message directly on the message-coding sequence and send them to Bob. By combining the checking and message-coding sequences together, Bob is able to read out the encoded messages directly. The scheme is secure because an eavesdropper cannot get both sequences simultaneously. We also discuss issues in a noisy channel.

description: On taking a non-trivial and semi-transitive bi-relation constituted by two (hard and soft) binary relations, we report a (i) p-continuity assumption that guarantees the completeness and transitivity of its soft part, and a (ii) characterization of a connected topological space in terms of its attendant properties on the space. Our work generalizes antecedent results in applied mathematics, all following Eilenberg (1941), and now framed in the context of a parametrized-topological space. This re-framing is directly inspired by the continuity assumption in Wold (1943-44) and the mixture-space structure proposed in Herstein and Milnor (1953), and the unifying synthesis of these pioneering but neglected papers that it affords may have independent interest.

description: Dissipative Kerr-microresonator soliton combs (hereafter called soliton combs) are promising to realize chip scale integration of full soliton comb systems providing high precision, broad spectral coverage and a coherent link to the micro/mm/THz domain with diverse applications coming on line all the time. However, the large soliton comb spacing hampers some applications. For example, for spectroscopic applications, there are simply not enough comb lines available to sufficiently cover almost any relevant absorption features. Here, we overcome this limitation by scanning the comb mode spacing by employing PDH locking and a microheater on the microresonator, showing continuous scanning of the soliton comb modes across nearly the full FSR of the microresonator without losing soliton operation, while spectral features with a bandwidth of as small of 5 MHz are resolved. Thus, comb mode scanning allows to cover the whole comb mode spectrum of tens of THz bandwidth with only one chip-scale comb.

description: Against the background of the Middle East conflict we study the role of social embeddedness of economic actors belonging to both conflicting parties for their perceptions of transaction problems and capabilities to solve them. Our analysis is based on a quantitative survey among Israeli food wholesalers. We find vivid economic relationships between Israeli and Palestinian traders, no particular problems occur. Continuity of business relations points to a strong role of social embeddedness. Arabic is frequently used in communication referring to an important role of institutional embeddedness. Various trade impediments due to the conflict do not impact Israeli but Palestinian traders.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: We present time-series, high-resolution optical spectroscopy of the eccentric T Tauri binary TWA 3A. Our analysis focuses on variability in the strength and structure of the accretion tracing emission lines H alpha and He I 5876A. We find emission line strengths to display the same orbital-phase dependent behavior found with time-series photometry, namely, bursts of accretion near periastron passages. Such bursts are in good agreement with numerical simulations of young eccentric binaries. During accretion bursts, the emission of He I 5876A consistently traces the velocity of the primary star. After removing a model for the system's chromospheric emission, we find the primary star typically emits ~70% of the He I accretion flux. We interpret this result as evidence for circumbinary accretion streams that preferentially feed the TWA 3A primary. This finding is in contrast to most numerical simulations, which predict the secondary should be the dominant accretor in a binary system. Our results may be consistent with a model in which the precession of an eccentric circumbinary disk gap alternates between preferentially supplying mass to the primary and secondary.

description: Our topic is the use of machine learning to improve software by making choices which do not compromise the correctness of the output, but do affect the time taken to produce such output. We are particularly concerned with computer algebra systems (CASs), and in particular, our experiments are for selecting the variable ordering to use when performing a cylindrical algebraic decomposition of $n$-dimensional real space with respect to the signs of a set of polynomials. In our prior work we explored the different ML models that could be used, and how to identify suitable features of the input polynomials. In the present paper we both repeat our prior experiments on problems which have more variables (and thus exponentially more possible orderings), and examine the metric which our ML classifiers targets. The natural metric is computational runtime, with classifiers trained to pick the ordering which minimises this. However, this leads to the situation were models do not distinguish between any of the non-optimal orderings, whose runtimes may still vary dramatically. In this paper we investigate a modification to the cross-validation algorithms of the classifiers so that they do distinguish these cases, leading to improved results.

Process Influence-Net Map, pair-wise ranking and matrix scoring tools were used. Results show lack of political will, inadequate finance, weak veterinary institutions. The study reveals the best integration approach as the moderate integration system. It recommends that for paraprofessionals to be integrated as part of the veterinary system; the Veterinary Surgeon Act and paraprofessional bill needs to be passed, the Uganda veterinary board should be strengthened, veterinary service providers should be organized and trained.

description: We use contemporaneous causality tests based on instrumental variables (IV) methods to re-examine causality from Commodity Index Trader positions to agricultural futures prices. A number of recent studies found that no Granger-causal impacts are discernible for agricultural commodity markets. Market microstructure theory suggests that the impact of index-based trading on agricultural futures markets should be contemporaneous and the data should fail to support Granger-causality despite the presence of a contemporaneous causal. IV-based tests for contemporaneous causality provide evidence for impacts in six of the twelve commodities. These are predominantly the less active contracts as measured by open interest.
The little things matter: relating the abundance of ultrafaint satellites to the hosts' assembly history

description: Ultrafaint dwarf galaxies ($M_\star\lesssim10^{5-6}\,{\rm M}_\odot$) are relics of an early phase of galaxy formation. They contain some of the oldest and most metal-poor stars in the Universe which likely formed before the epoch of hydrogen reionisation. These galaxies are so faint that they can only be detected as satellites of the Milky Way. They are so small that they are just barely resolved in current cosmological hydrodynamics simulations. Here we combine very high resolution cosmological $N$-body simulations with a semi-analytic model of galaxy formation to study the demographics and spatial distribution of ultrafaint satellites in Milky Way-mass haloes. We show that the abundance of these galaxies is correlated with the assembly history of the host halo: at fixed mass, haloes assembled earlier contain, on average, more ultrafaint satellites today than haloes assembled later. We identify simulated galactic haloes that experience an ancient Gaia-Enceladus-Sausage-like and a recent LMC-like accretion event and find that the former occurs in 33% of the sample and the latter in 9%. Only 3% experience both events and these are especially rich in ultrafaint satellites, most acquired during the ancient accretion event. Our models predict that the radial distribution of satellites is more centrally concentrated in early-forming haloes. Accounting for the depletion of satellites by tidal interactions with the central disc, we find a very good match to the observed radial distribution of satellites in the Milky Way over the entire radial range. This agreement is mainly due to the ability of our model to track 'orphan' galaxies after their subhaloes fall below the resolution limit of the simulation.

description: The interaction rate of an ultrarelativistic active neutrino at a temperature below the electroweak crossover plays a role in leptogenesis scenarios based on oscillations between active neutrinos and GeV-scale sterile neutrinos. By making use of a Euclideanization property of a thermal light-cone correlator, we determine the $O(g)$ correction to such an interaction rate in the high-temperature limit $πT \gg m_W$, finding a $\sim 15 ... 40\%$ reduction. For a benchmark point, this NLO correction decreases the lepton asymmetries produced by $\sim 1\%$.

 Material examined (2 spec.). YEMEN: SOCOTRA ISLAND: Gubbah di-Net, 12°28′52.9″N, 53°23′07.4″E, 2 m a.s.l., 28.x.2010, at light, 2 spec., lgt. & det. R.F.F.L. Felix (revid. by P. Bulirsch) (RFBE).
 Diagnosis. Body length 3.9–5.0 mm. Almost black, shiny. Pronotum longer than wide, elytra parallel-sided. Frontoclypeal suture V-shaped. Two apical and three humeral pores on elytra.
 Comments on classification. According to FEDORENKO (1996) the specimens from Socotra belong to the subspecies Dyschirius auriculatus smithi Kult, 1954, described from Erytrea, with the pronotum and elytra slightly shorter than in the nominate form. According to P. Bulirsch (pers. comm., 2012), the subspecies is probably a synonym of the nominate subspecies.
 Collection circumstances. Both specimens were collected at light in a saltmarsh.
 Distribution. Known from Africa, Saudi Arabia and mainland Yemen. First record from Socotra Island.

description: We compare the evolution of spectral shape with luminosity in GRS 1915+105 with that of 'normal' black holes. The pathological time variability of GRS 1915+105 does not indicate that it belongs in a different class to all the other objects. At comparable fraction of Eddington luminosity its spectra and (more importantly) time variability behaviour are similar to that seen in the 'normal' black holes. Its unique limit-cycle variability only appears when it radiates at uniquely high (super-Eddington) luminosities.

description: This contribution emerged as part of the collaborative project “Data network for better European organic market information” carried out in the 7th Framework Programme of the EU. Data from a survey among organic market data collectors form the basis for the analysis of the current situation of statistics on organic market data. The results reveal a heterogeneous picture, because organic market growth and data collection within the organic food sector have developed differently throughout Europe. Building on the survey results, the quality of data collection approaches is evaluated through the application of the data quality dimensions relevance, accuracy, comparability, coherence, accessibility/clarity, and timeliness/punctuality (Eurostat, 2009).

description: Farmers’ decision-making behaviour limits the amount of straw available on the market in Bavaria. Besides using straw as humus and nutrient source for soil, or as litter, it can be also used for producing chemical products or energy. The research purpose is to determine the factors affecting farmers’ willingness to sell straw as a by-product of the agricultural production process for material and energy use. It also aims to estimate potential straw amounts at specific price levels which will be available in Bavaria.

Hot Spots and Pseudogaps for Hole- and Electron-Doped High-Temperature Superconductors

description: Using cluster perturbation theory, it is shown that the spectral weight and pseudogap observed at the Fermi energy in recent Angle Resolved Photoemission Spectroscopy (ARPES) of both electron and hole-doped high-temperature superconductors find their natural explanation within the t-t'-t''-U Hubbard model in two dimensions. The value of the interaction U needed to explain the experiments for electron-doped systems at optimal doping is in the weak to intermediate coupling regime where the t-J model is inappropriate. At strong coupling, short-range correlations suffice to create a pseudogap but at weak coupling long correlation lengths associated with the antiferromagnetic wave vector are necessary.

description: Classification of intermediate redshift ($z$ = 0.3--0.8) emission line galaxies as star-forming galaxies, composite galaxies, active galactic nuclei (AGN), or low-ionization nuclear emission regions (LINERs) using optical spectra alone was impossible because the lines used for standard optical diagnostic diagrams: [NII], H$α$, and [SII] are redshifted out of the observed wavelength range. In this work, we address this problem using four supervised machine learning classification algorithms: $k$-nearest neighbors (KNN), support vector classifier (SVC), random forest (RF), and a multi-layer perceptron (MLP) neural network. For input features, we use properties that can be measured from optical galaxy spectra out to $z < 0.8$---[OIII]/H$β$, [OII]/H$β$, [OIII] line width, and stellar velocity dispersion---and four colors ($u-g$, $g-r$, $r-i$, and $i-z$) corrected to $z=0.1$. The labels for the low redshift emission line galaxy training set are determined using standard optical diagnostic diagrams. RF has the best area under curve (AUC) score for classifying all four galaxy types, meaning highest distinguishing power. Both the AUC scores and accuracies of the other algorithms are ordered as MLP$>$SVC$>$KNN. The classification accuracies with all eight features (and the four spectroscopically-determined features only) are 93.4% (92.3%) for star-forming galaxies, 69.4% (63.7%) for composite galaxies, 71.8% (67.3%) for AGNs, and 65.7% (60.8%) for LINERs. The stacked spectrum of galaxies of the same type as determined by optical diagnostic diagrams at low redshift and RF at intermediate redshift are broadly consistent. Our publicly available code (https://github.com/zkdtc/MLC_ELGs) and trained models will be instrumental for classifying emission line galaxies in upcoming wide-field spectroscopic surveys.

description: In this paper, we explore the entropy uncertainty for qutrit system under non-Markov noisy environment and discuss the effects of the quantum memory system and the spontaneously generated interference (SGI) on the entropy uncertainty in detail. The results show that, the entropy uncertainty can be reduced by using the methods of quantum memory system and adjusting of SGI. Particularly, the entropy uncertainty can be decreased obviously when both the quantum memory system and the SGI are simultaneously applied.

description: A class of vector coherent states is derived with multiple of matrices as vectors in a Hilbert space, where the Hilbert space is taken to be the tensor product of several other Hilbert spaces. As examples vector coherent states with multiple of quaternions and octonions are given. The resulting generalized oscillator algebra is briefly discussed. Further, vector coherent states for a tensored Hamiltonian system are obtained by the same method. As particular cases, coherent states are obtained for tensored Jaynes-Cummings type Hamiltonians and for a two-level two-mode generalization of the Jaynes-Cummings model.

description: A larger U.S. share of world trade helped push U.S. agricultural export value in the first 11 months of fiscal year (FY) 1987 to $25.5 billion, $1.1 billion over that of the same period of FY 1986. U.S. agricultural imports in the first 11 months of FY 1987 eased to $19.1 billion, 1 percent below the record highs of the same period in FY 1986. Prices for most products fell after June as Southern Hemisphere crops reached European markets, U.S. crops basked in favorable weather, and continued moderate increases in wages and U.S. import prices eased fears of resurgent inflation. U.S. agricultural exports generate employment, income, and purchasing power in the farm and nonfarm sectors.

description: We present the star formation history (SFH) of the isolated (D~970 kpc) Local Group dwarf galaxy WLM measured from color-magnitude diagrams constructed from deep Hubble Space Telescope imaging. Our observations include a central (0.5 $r_h$) and outer field (0.7 $ r_h$) that reach below the oldest main sequence turnoff. WLM has no early dominant episode of star formation: 20% of its stellar mass formed by ~12.5 Gyr ago (z~5). It also has an SFR that rises to the present with 50% of the stellar mass within the most recent 5 Gyr (z<0.7). There is evidence of a strong age gradient: the mean age of the outer field is 5 Gyr older than the inner field despite being only 0.4 kpc apart. Some models suggest such steep gradients are associated with strong stellar feedback and dark matter core creation. The SFHs of real isolated dwarf galaxies and those from the the Feedback In Realistic Environment suite are in good agreement for $M_{\star}(z=0) \sim 10^7-10^9 M_{\odot}$, but in worse agreement at lower masses ($M_{\star}(z=0) \sim 10^5-10^7 M_{\odot}$). These differences may be explainable by systematics in the models (e.g., reionization model) and/or observations (HST field placement). We suggest that a coordinated effort to get deep CMDs between HST/JWST (crowded central fields) and WFIRST (wide-area halo coverage) is the optimal path for measuring global SFHs of isolated dwarf galaxies.

description: Outflows are a pervasive feature of mechanical feedback from super star clusters (SSC) in starburst galaxies, playing a fundamental role in galaxy evolution. Observations are now starting to confirm that outflows can undergo catastrophic cooling, suppressing adiabatic superwinds. Here we present a suite of one-dimensional, hydrodynamic simulations that study the ionization structure of these outflows and the resulting line emission generated by the cooling gas. We use the non-equilibrium atomic chemistry package within MAIHEM, our modified version of FLASH, which evolves the ionization state of the gas and computes the total cooling rate on an ion-by-ion basis. We find that catastrophically cooling models produce strong nebular line emission compared to adiabatic outflows. We also show that such models exhibit non-equilibrium conditions, thereby generating more highly ionized states than equivalent equilibrium models. When including photoionization from the parent SSC, catastrophically cooling models show strong C IV λ1549 and O VI λ1037 emission. For density bounded photoionization, He II λ1640, λ4686, C III] λ1908, Si IV λ1206, and Si III λ1400 are also strongly enhanced. These lines are seen in extreme starbursts where catastrophic cooling is likely to occur, suggesting that they may serve as diagnostics of such conditions. The higher ionization generated by these flows may help to explain line emission that cannot be attributed to SSC photoionization alone.

description: We analyze the way topological constraints and inhomogeneity in the excitability influence the dynamics of spiral waves on spheres and punctured spheres of excitable media. We generalize the definition of an index such that it characterizes not only each spiral but also each hole in punctured, oriented, compact, two-dimensional differentiable manifolds and show that the sum of the indices is conserved and zero. We also show that heterogeneity and geometry are responsible for the formation of various spiral wave attractors, in particular, pairs of spirals in which one spiral acts as a source and a second as a sink -- the latter similar to an antispiral. The results provide a basis for the analysis of the propagation of waves in heterogeneous excitable media in physical and biological systems.
