description: We present the relation of the spatial distribution of H-alpha kernels with the distribution of hard X-ray (HXR) sources seen during the 2001 April 10 solar flare. This flare was observed in H-alpha with the (Sartorius) telescope at Kwasan Observatory, Kyoto University, and in hard X-rays (HXRs) with the Hard X-ray Telescope (HXT) onboard Yohkoh. We compared the spatial distribution of the HXR sources with that of the H-alpha kernels. While many H-alpha kernels are found to brighten successively during the evolution of the flare ribbons, only a few radiation sources are seen in the HXR images. We measured the photospheric magnetic field strengths at each radiation source in the H-alpha images, and found that the H-alpha kernels accompanied by HXR radiation have magnetic strengths about 3 times larger than those without HXR radiation. We also estimated the energy release rates based on the magnetic reconnection model. The release rates at the H-alpha kernels with accompanying HXR sources are 16-27 times larger than those without HXR sources. These values are sufficiently larger than the dynamic range of HXT, which is about 10, so that the difference between the spatial distributions of the H$α$ kernels and the HXR sources can be explained.

description: We show that any embedding of a planar graph can be encoded succinctly while efficiently answering a number of topological queries near-optimally. More precisely, we build on a succinct representation that encodes an embedding of $m$ edges within $4m$ bits, which is close to the information-theoretic lower bound of about $3.58m$. With $4m+o(m)$ bits of space, we show how to answer a number of topological queries relating nodes, edges, and faces, most of them in any time in $ω(1)$. Further, we show that with $O(m)$ bits of space we can solve all those operations in $O(1)$ time.

description: For a practical quantum computer to operate, it will be essential to properly manage decoherence. One important technique for doing this is the use of "decoherence-free subspaces" (DFSs), which have recently been demonstrated. Here we present the first use of DFSs to improve the performance of a quantum algorithm. An optical implementation of the Deutsch-Jozsa algorithm can be made insensitive to a particular class of phase noise by encoding information in the appropriate subspaces; we observe a reduction of the error rate from 35% to essentially its pre-noise value of 8%.

description: We prove that the closure of every Jordan class J in a semisimple simply connected complex group G at a point x with Jordan decomposition x = rv is smoothly equivalent to the union of closures of those Jordan classes in the centraliser of r that are contained in J and contain x in their closure. For x unipotent we also show that the closure of J around x is smoothly equivalent to the closure of a Jordan class in Lie(G) around exp^{-1}x. For G simple we apply these results in order to determine a (non-exhaustive) list of smooth sheets in G, the complete list of regular Jordan classes whose closure is normal and Cohen-Macaulay, and to prove that all sheets and Lusztig's strata in SL(n,C) are smooth.

description: Using density-functional theory (DFT) we investigate the incorporation of oxygen directly below the Rh(111) surface. We show that oxygen incorporation will only commence after nearly completion of a dense O adlayer (θ_tot = 1.0 monolayer) with O in the fcc on-surface sites. The experimentally suggested octahedral sub-surface site occupancy, inducing a site-switch of the on-surface species from fcc to hcp sites, is indeed found to be a rather low energy structure. Our results indicate that at even higher coverages oxygen incorporation is followed by oxygen agglomeration in two-dimensional sub-surface islands directly below the first metal layer. Inside these islands, the metastable hcp/octahedral (on-surface/sub-surface) site combination will undergo a barrierless displacement, introducing a stacking fault of the first metal layer with respect to the underlying substrate and leading to a stable fcc/tetrahedral site occupation. We suggest that these elementary steps, namely, oxygen incorporation, aggregation into sub-surface islands and destabilization of the metal surface may be more general and precede the formation of a surface oxide at close-packed late transition metal surfaces.

Rezultati istraživanja su pokazali da hrvatski potrošači kave najčešće kupuju kavu u supermarketima. Potrošači kave u Hrvatskoj nisu lojalni određenim vrstama kave pa će tako u slučaju da prilikom kupovine željena kava nije dostupna, kupiti neku drugu kavu. Ispitanici najčešće piju jednu šalicu ili jednu do dvije šalice kave dnevno, uglavnom u prijepodnevnim satima, pri čemu najčešće odabiru crnu ili „tursku“ kavu i espresso. Najčešći motiv za konzumaciju kave je navika, ali i pozitivni učinci kave na probavu, opće stanje i smirenje. Na temelju rezultata istraživanja preporuča se promidžba učinaka koje kava ima na ljudski organizam, kao i povećanje dostupnosti kave na mjestima kupovine i konzumacije kave. Također, potrošače koji nemaju jasno izrađene preferencije prema uobičajenim napitcima, potrebno je privući agresivnijim promotivnim kampanjama. Dobiveni rezultati značajni su za proizvođače i distributere u svrhu predviđanja budućih kretanja na tržištu te kreiranja njihovih marketinških strategija.

description: The market share of organic food in Switzerland is high compared with that in other European countries, and has grown notably in recent years. However, little is known about why the market share of certain organic food products is higher than that of others. Swiss household expenditure data distinguishing between organic and conventional products allow an analysis at the product level. As a result, factors which determine the market share level of different organic food products are identified. Based on the results of the analysis, the driving factors are categorised into three dimensions. First, a low level of processing is positively related to a high organic market share, suggesting that communicating the benefits of organic food is more successful for unprocessed than for processed products. Second, it appears that the organic consumer in Switzerland is rather critical about buying products that are relatively expensive compared to their conventional counterpart. Products with high price premiums as well as products that are of particular importance for the household in terms of its food budget, therefore, have a clear disadvantage on the market, suggesting that consumers of organic food are price-conscious. Third, Swiss consumers seem to have a high preference for domestically produced organic products, since the characteristic of being an imported product is negatively related to the organic market share level. The results give a first understanding of what is important to Swiss consumers when it comes to the consumption of organic food and imply that supporting organic food production in Switzerland is still promising from a policy perspective as long as the price premium for organic quality stays at a reasonable level.
Negative contributions to entropy production induced by quantum coherences

description: The entropy production in dissipative processes is the essence of the arrow of time and the second law of thermodynamics. For dissipation of quantum systems, it was recently shown that the entropy production contains indeed two contributions: a classical one and a quantum one. Here we show that for degenerate (or near-degenerate) quantum systems there are additional quantum contributions which, remarkably, can become negative. Furthermore, such negative contributions are related to significant changes in the ongoing thermodynamics. This includes phenomena such as generation of coherences between degenerate energy levels (called horizontal coherences), alteration of energy exchanges and, last but not least, reversal of the natural convergence of the populations toward the thermal equilibrium state. Going further, we establish a complementarity relation between horizontal coherences and population convergence, particularly enlightening for understanding heat flow reversals. Conservation laws of the different types of coherences are derived. Some consequences for thermal machines and resource theory of coherence are suggested.

description: This paper presents factor productivity growth measures in the European food industry over the period 2001-2008 by using data envelopment analysis. The Malmquist productivity growth indicator is used to identify the contributions of technical change, technical efficiency change and scale change. The study contributes to the literature by analysing the dairy and meat processing industries in eight European countries based on a sample of 4,584 firms. Results will underline differences between these countries concerning the productivity growth measures as well as differences between different company sizes. Further research should include an impulse response analysis for the effect of investment spikes.

description: We obtain a Bekenstein entropy bound for the charged objects in arbitrary dimensions ($D\ge 4$) using the D-bound recently proposed by Bousso. With the help of thermodynamics of CFTs corresponding to AdS Reissner-Norström (RN) black holes, we discuss the relation between the Bekenstein and Bekenstein-Verlinde bounds. In particular we propose a Bekenstein-Verlinde-like bound for the charged systems. In the Einstein-Maxwell theory with a negative cosmological constant, we discuss the brane cosmology with positive tension using the Binetruy-Deffayet-Langlois approach. The resulting Friedman-Robertson-Walker equation can be identified with the one obtained by the moving domain wall approach in the AdS RN black hole background. Finally we also address the holographic property of the brane universe.

description: This paper systematically investigates the role of the quality of rural employment on agricultural production efficiency in developing countries, taking Ethiopia and Tanzania as cases. We use data of the Living Standards Measurement Study-Integrated Surveys on Agriculture (LSMS-ISA) collected in 2011. In the analysis, an output-oriented distance function approach that accounts for different technological, demographic, socio-economic, institutional and quality of rural employment indicators is applied. The findings of the analysis support the idea that the quality of rural employment could be seen as an effective element of rural development policies and strategies in sub-Saharan Africa. Better integration of quality rural employment aspects (creation of jobs, improving quality of jobs, promoting public employment programs etc.) contribute to improve technical efficiency in agricultural production.

The saddle-point configuration corresponds to the creation and annihilation of a vortex localized around the Dirac string needed to support the nontrivial background. This configuration is generalized to the case in which a nonlocal Maxwell term is allowed in order to fulfill the finite action requirement. Following 't Hooft procedure, we compute the vortex correlation functions and we study the possibility of obtaining spin 1/2 excitations. A possible connection with the bosonization of interacting three-dimensional massive fermionic systems is also discussed.

Auxiliary Tasks to Boost Biaffine Semantic Dependency Parsing

Subjects: subject: Computation and Language (cs.CL)

description: The biaffine parser of Dozat and Manning (2017) was successfully extended to semantic dependency parsing (SDP) (Dozat and Manning, 2018). Its performance on graphs is surprisingly high given that, without the constraint of producing a tree, all arcs for a given sentence are predicted independently from each other (modulo a shared representation of tokens). To circumvent such an independence of decision, while retaining the O(n^2) complexity and highly parallelizable architecture, we propose to use simple auxiliary tasks that introduce some form of interdependence between arcs. Experiments on the three English acyclic datasets of SemEval 2015 task 18 (Oepen et al., 2015), and on French deep syntactic cyclic graphs (Ribeyre et al., 2014) show modest but systematic performance gains on a near state-of-the-art baseline using transformer-based contextualized representations. This provides a simple and robust method to boost SDP performance.

description: This article examines the impact of a joint organic and fair trade certification on productivity and material costs based on data collected from 277 smallholder black pepper farmers in India. We estimate a multinomial endogenous switching regression along with a counterfactual analysis to ascertain the effects of certification. Our results indicate that certified farmers have higher yields. Counterfactual study shows that conventional farmers can increase their yields by 35% with less than half the costs by venturing into organic and fair trade networks. Further, treatment and transitional heterogeneity effects reveal that a joint organic and fair trade certification has the strongest effect on productivity for the less successful farmers.

description: Apple production is afflicted with various risks. As it is a permanent crop, apple producers are less flexible to react upon undesirable events. As a result, for a sustainable economic performance, the determination of efficient farming options, as a combination of the production system and risk management instruments (RMI), is crucial. Our investigation focuses on this choice problem utilizing stochastic dominance criteria, which apply to a wide range of risk preferences. Based on data for 134 apple producers operating in the two main production areas in Germany, we compare and determine efficient production options for the most common regional varieties. Furthermore, appropriate RMIs are identified using stochastic dominance criteria. In this context we investigate internal RMI (frost irrigation and hail nets) as well as external risk protection tools (insurance options). In Germany only a single insurance concept against hail is available, whereas insurance against late frosts is not at the apple growers’ disposal. As frost insurance exists in neighboring countries, we analyze the effect of the latter based on a hypothetic hail-frost insurance policy. Simulated net present values of a one hectare level serve as decision criterion, for which the associated cumulative probability distributions are evaluated according to first and second degree stochastic dominance criteria. In addition, we use SERF (Stochastic Efficiency with Respect to a Function) as it evaluates farming options for defined ranges of relative risk aversion and thus has a higher discriminative power. The results indicate that Red Prince is the most efficient option in the north and subsidized hail insurance with frost irrigation is superior to frost irrigation as single RMI. In the south Braeburn should be chosen under rational aspects, but the tested insurance solutions are not as efficient as the common production practice under hail nets.

description: We exploit a well-known isomorphism between complex hermitian $2\times 2$ matrices and $\mathbb{R}^4$, which yields a convenient real vector representation of qubit states. Because these do not need to be normalized we find that they map onto a Minkowskian future cone in $\mathbb{E}^{1,3}$, whose vertical cross-sections are nothing but Bloch spheres. Pure states are represented by light-like vectors, unitary operations correspond to special orthogonal transforms about the axis of the cone, positive operations correspond to pure Lorentz boosts. We formalize the equivalence between the generalized measurement formalism on qubit states and the Lorentz transformations of special relativity, or more precisely elements of the restricted Lorentz group together with future-directed null boosts. The note ends with a discussion of the equivalence and some of its possible consequences.

We further comment on the possibility of disentangling the properties of the underlying theory featuring the first order phase transition should a stochastic gravitational wave signal be discovered.

description: Using a moment based approach, introduced by Antle for producers’ risk behavior elicitation, we develop an empirical model to evaluate the implication of risk preferences on farm portfolio decisions. With a comprehensive household level panel data of rounds of 2004 and 2009, we estimate risk aversion behavior of farm households in uncertain climate and market imperfections. To solve the problem of endogeneity, the risk parameter is instrumented in a two stage maximum likelihood estimation technique, and used as a determinant of the level of farm level diversification. We find that farmers with higher level of relative risk premium will more likely opt for diversified farms. The engagement of farm households to off and non-farm income generating activities could likely reduce the on-farm diversification level. On-farm diversification and engagement in off-farm and non-farm activities can be considered as substitutable risk mitigation strategies

description: Extreme value statistics (EVS) concerns the study of the statistics of the maximum or the minimum of a set of random variables. This is an important problem for any time-series and has applications in climate, finance, sports, all the way to physics of disordered systems where one is interested in the statistics of the ground state energy. While the EVS of `uncorrelated' variables are well understood, little is known for strongly correlated random variables. Only recently this subject has gained much importance both in statistical physics and in probability theory. In this review, we will first recall the classical EVS for uncorrelated variables and discuss the three universality classes of extreme value limiting distribution, known as the Gumbel, Fréchet and Weibull distribution. We then show that, for weakly correlated random variables with a finite correlation length/time, the limiting extreme value distribution can still be inferred from that of the uncorrelated variables using a renormalisation group-like argument. Finally, we consider the most interesting examples of strongly correlated variables for which there are very few exact results for the EVS. We discuss few examples of such strongly correlated systems (such as the Brownian motion and the eigenvalues of a random matrix) where some analytical progress can be made. We also discuss other observables related to extremes, such as the density of near-extreme events, time at which an extreme value occurs, order and record statistics, etc.

description: Commodity multicore systems are increasingly adopting hardware support that enables the system software to partition the last-level cache (LLC). This support makes it possible for the operating system (OS) or the Virtual Machine Monitor (VMM) to mitigate shared-resource contention effects on multicores by assigning different co-running applications to various cache partitions. Recently cache-clustering (or partition-sharing) strategies have emerged as a way to improve system throughput and fairness on new platforms with cache-partitioning support. As opposed to strict cache-partitioning, which allocates separate cache partitions to each application, cache-clustering allows partitions to be shared by a group of applications.
 In this article we propose LFOC+, a fairness-aware OS-level cache-clustering policy for commodity multicore systems. LFOC+ tries to mimic the behavior of the optimal cache-clustering solution for fairness, which we could obtain for different workload scenarios by using a simulation tool. Our dynamic cache-clustering strategy continuously gathers data from performance monitoring counters to classify applications at runtime based on the degree of cache sensitivity and contentiousness, and effectively separates cache-sensitive applications from aggressor programs to improve fairness, while providing acceptable system throughput.
 We implemented LFOC+ in the Linux kernel and evaluated it on a real system featuring an Intel Skylake processor, where we compare its effectiveness to that of four previously proposed cache-clustering policies. Our experimental analysis reveals that LFOC+ constitutes a lightweight OS-level policy and improves fairness relative to two other state-of-the-art fairness-aware strategies --Dunn and LFOC--, by up to 22\% and up to 20.6\%, respectively, and by 9\% and 4.9\% on average.

description: This paper analyzes the structure of water transactions using data on contract duration from California. Water rights in the western United States are transferred through short-term and longterm leases as well as permanent ownership contracts. We test predictions about the type of water contracts derived from the literature on economic organization by using ordered probit models to investigate the correlates of contract duration.We confirm that long-term and permanent contracts are more likely when investments in specific assets are required for conveyance. We also find that longer-term arrangements are common when buyers with uncertain water supplies purchase from sellers with more certain rights, suggesting that urban municipalities use long-term contracts to reduce risk. We do not find robust evidence supporting the hypothesis that short-term agreements are more likely when the costs of transfer to third parties are potentially high.

description: We report the results of a radial velocity survey of planetary nebulae (PNe) located in the tidal features of the well-known interacting system NGC 5194/95 (M51). We find clear kinematic evidence that M51's northwestern tidal debris consists of two discrete structures which overlap in projection -- NGC 5195's own tidal tail, and diffuse material stripped from NGC 5194. We compare these kinematic data to a new numerical simulation of the M51 system, and show that the data are consistent with the classic ``single passage'' model for the encounter, with a parabolic satellite trajectory and a 2:1 mass ratio. We also comment on the spectra of two unusual objects: a high-velocity PN which may be associated with NGC 5194's halo, and a possible interloping high-redshift galaxy.

description: In this study, novel flexible micro-scale humidity sensors were directly fabricated in graphene oxide (GO) and polyimide (PI) using ion beam writing without any further modifications, and then successfully tested in an atmospheric chamber. Two low fluences of carbon ions with an energy of 5 MeV were used, and structural changes in the irradiated materials were expected. The shape and structure of prepared micro-sensors were studied using scanning electron microscopy (SEM). The structural and compositional changes in the irradiated area were characterized using micro-Raman spectroscopy, X-ray photoelectron spectroscopy (XPS), Rutherford back-scattering spectroscopy (RBS), energy-dispersive X-ray spectroscopy (EDS), and elastic recoil detection analysis (ERDA) spectroscopy. The sensing performance was tested at a relative humidity (RH) ranging from 5 % to 60 %, where the electrical conductivity of PI varied by three orders of magnitude, and the electrical capacitance of GO varied in the order of pico-farads. In addition, the PI sensor has proven long-term sensing stability in air. We demonstrated a novel method of ion micro-beam writing to prepare flexible micro-sensors that function over a wide range of humidity and have good sensitivity and great potential for widespread applications.

description: Most common property resource (CPR) collection in developing countries occurs in imperfect market environments, in which endogenous prices link the economic returns in non-resource activities (i.e., agriculture) with effort supplied to CPR collection. A model of an imperfectly integrated rural household demonstrates the theoretically ambiguous connection between agricultural productivity and resource collection. Using unique panel data from rural Mexico, we find evidence that households with higher agricultural efficiency supply less labor to CPR collection. Interventions that raise agricultural productivity thus may complement resource conservation efforts.

description: A tight-binding model is fit to first-principles calculations for copper that include structures distorted according to elastic constants and high-symmetry phonon modes. With the resulting model the first-principles-based phonon dispersion and the free energy are calculated in the quasi-harmonic approximation. The resulting thermal expansion, the temperature- and volume-dependence of the elastic constants, the Debye temperature, and the Gruneisen parameter are compared with available experimental data.

Lykia Orografyası

description: Lykia’nın tarihsel ve kültürel coğrafyasını anlamak açısından oldukça önemli olan dağlar, bu önemlerine karşın yeterince araştırılmış bir konu değildir. Bunun en belirgin kanıtı Lykia orografyasına ilişkin 100 yılı aşkın bir süredir koruna gelen yanlışlar yumağıdır. Bunun ana nedeni, isimlendirmelerin temelini, bölgeye uğramadığı açık olan Strabon’un çelişik anlatımlarının oluşturmasıdır. Buna göre, Ksanthos Vadisi'nin batı yakasını örten Baba Dağı Kragos, San Dağı Antikragos ile; Ksanthos Vadisi’nin doğusunu kuşatan ve etekleri kuzeyde Boncuk Dağları ile birleşen Akdağ, Masikytos ile ve Lykia’nın doğu’da Pamphylia ile sınırlarını oluşturan Beydağları ise Solyma ile özdeşlenmişlerdi. Oronyma bu şekilde oluşturulunca, Lykia’nın üç büyük dağ silsilesinden biri olan Boncuk Dağları'nın, antik yazarların dikkatinden kaçtığını düşünmek; buna karşın ülkenin bu en büyük ve en yüksek üç dağ silsilesinin yanında oldukça küçük ve önemsiz kalan Baba Dağı’nı Lykia'nın en ünlü dağı Kragos'un yerine koymak gibi mantık dışı bir yorumdan başkası mümkün gözükmemektedir. Antik kaynaklarda, kendi içinde çelişen böyle bir durumun söz konusu olduğuna ilişkin bir çok işaret bulunmakla birlikte, konunun yeniden ele alınıp incelenmesine Patara'da 1994 yılında ele geçen Stadiasmus Patarensis Anıtı'ndaki bazı güzergah bilgileri vesile olmuştur.

description: When NAFTA became fully implemented for sugar in 2008, Mexico became the leading sugar exporter into the United States, accounting for nearly 70% of U.S. imports in 2013. A partial equilibrium trade model was developed to estimate the welfare implications of NAFTA for U.S. and Mexican sugar markets from 2008 to 2013. While the net effect of NAFTA on U.S. welfare and Mexican sugar producers was positive, U.S. sugar producers suffered significant losses. The net Mexican welfare effect of NAFTA was significantly positive in 2011, negative in 2008, and slightly positive in 2009–2010 and 2012–2013.
On the initial mass-radius relation of stellar clusters

description: Young stellar clusters across nearly five orders of magnitude in mass appear to follow a power-law mass-radius relationship (MRR), $R_{\star} \propto M_{\star}^α$, with $α\approx 0.2 - 0.33$. We develop a simple analytic model for the cluster mass-radius relation. We consider a galaxy disc in hydrostatic equilibrium, which hosts a population of molecular clouds that fragment into clumps undergoing cluster formation and feedback-driven expansion. The model predicts a mass-radius relation of $R_{\star} \propto M_{\star}^{1/2}$ and a dependence on the kpc-scale gas surface density $R_{\star} \propto Σ_{\rm g}^{-1/2}$, which results from the formation of more compact clouds (and cluster-forming clumps within) at higher gas surface densities. This environmental dependence implies that the high-pressure environments in which the most massive clusters can form also induce the formation of clusters with the smallest radii, thereby shallowing the observed MRR at high-masses towards the observed $R_{\star} \propto M_{\star}^{1/3}$. At low cluster masses, relaxation-driven expansion induces a similar shallowing of the MRR. We combine our predicted MRR with a simple population synthesis model and apply it to a variety of star-forming environments, finding good agreement. Our model predicts that the high-pressure formation environments of globular clusters at high redshift naturally led to the formation of clusters that are considerably more compact than those in the local Universe, thereby increasing their resilience to tidal shock-driven disruption and contributing to their survival until the present day.
