description: We have monitored the AGN 3C390.3 between 1995 and 2000.Two large amplitude outbursts, of different duration, in continuum and H beta light were observed ie.: in October 1994 a brighter flare that lasted about 1000 days and in July 1997 another one that lasted about 700 days were detected. The flux in the H beta wings and line core vary simultaneously, a behavior indicative of predominantly circular motions in the BLR.Important changes of the Hbeta emission profiles were detected: at times, we found profiles with prominent asymmetric wings, as those normaly seen in Sy1s, while at other times, we observe profiles with weak almost symmetrical wings, similar to those seen in Sy1.8s. We found that the radial velocity difference between the red and blue bumps is anticorrelated with the light curves of H beta and continuum radiation.e found that the radial velocity difference between the red and blue bumps is anticorrelated with the light curves of H-beta and continuum radiation. Theoretical H-beta profiles were computed for an accretion disk, the observed profiles are best reproduced by an inclined disk (25 deg) whose region of maximum emission is located roughly at 200 Rg. The mass of the black hole in 3C 390.3, estimated from the reverberation analysis is Mrev = 2.1 x 10^9 Msun, ie. 5 times larger than previous estimates

description: We derive a semi-classical nonequilibrium work identity by applying the Wigner-Weyl quantization scheme to the Jarzynski identity for a classical Hamiltonian. This allows us, to the leading order in $\hbar$, to overcome the problem of defining the concept of work in quantum mechanics. We propose a geometric interpretation of this semi-classical relation in terms of trajectories in a complex phase space and illustrate it with the exactly solvable case of the quantum harmonic oscillator.

description: The photo- and electroproduction of eta, eta-prime mesons on nucleons are investigated within a relativistic chiral unitary approach based on coupled channels. The s-wave potentials for electroproduction and meson-baryon scattering are derived from a chiral effective Lagrangian which includes the eta-prime as an explicit degree of freedom and incorporates important features of the underlying QCD Lagrangian such as the axial U(1) anomaly. The effective potentials are iterated in a Bethe-Salpeter equation and cross sections for eta, eta-prime photo- and electroproduction from nucleons are obtained. The results for the eta-prime photoproduction cross section on protons reproduce the appearance of an S_{11} resonance around 1.9 GeV observed at ELSA. The inclusion of electromagnetic form factors increases the predicted eta electroproduction cross sections on the proton, providing a qualitative explanation for the hard form factor of the photocoupling amplitude observed at CLAS.

description: Extreme events are becoming more frequent and intense, inflating the economic damages and social hardship set-off by natural catastrophes. Amidst budgetary cuts, there is a growing concern on societies’ ability to design solvent disaster recovery strategies, while addressing equity and affordability concerns. The participation of private sector along with public one through Public-Private Partnerships (PPPs) has gained on importance as a means to address these seemingly conflicting objectives through the provision of (catastrophic) natural hazard insurance. This is the case of many OECD countries, notably some EU Member States such as the United Kingdom and Spain. The EU legislator has adapted to this new scenario and recently produced major reforms in the legislation and regulation that govern the framework in which PPPs for (catastrophic) natural hazard insurance develop. This paper has a dual objective: 1) review the complex legal background that rules the provision of insurance against natural catastrophes in the EU after these major reforms; 2) assess the implications of the reforms and offer concise Policy Guiding Principles.

description: Many future climate scenarios suggest that much of southern Australia could potentially experience higher temperatures and less rainfall. Consequently, livestock production is likely to become more challenging in the future. Managing these risks by examining the potential economic impact of alternative futures is a sensible approach for wool producers to consider in the face of predicted changes in climate. In this paper a way of thinking about the impacts of climate change is presented for wool producers in Yass, New South Wales. Continued genetic improvement will assist in reducing the impact of climate change on operating profit. The long term outlook for wool production and the demand from global markets needs to be considered in a whole farm approach.

description: A quadratic semiclassical theory, regarding the interaction of gravity with a massive scalar quantum field, is considered in view of the renormalizable energy-momentum tensor in a multi-dimensional curved spacetime. According to it, a self-consistent coupling between the square curvature term R^{2} and the quantum field Φshould be introduced in order to yield the "correct" renormalizable energy-momentum tensor in quadratic gravity theories. The subsequent interaction discards any higher-order derivative terms from the gravitational field equations, but, in the expence, it introduces a geometric source term in the wave equation for the quantum field. Unlike the conformal coupling case (RΦ^{2}), this term does not represent an additional "mass" and, therefore, the quantum field interacts with gravity not only through its mass (or energy) content (~Φ^{2}), but also, in a more generic way (R^{2}Φ). Within this context, we propose a general method to obtain mode-solutions for the quantum field, by means of the associated Green's function in an anisotropic six-dimensional background.

description: We consider testing the ability of quantum network nodes to execute multi-round quantum protocols. Specifically, we examine protocols in which the nodes are capable of performing quantum gates, storing qubits and exchanging said qubits over the network a certain number of times. We propose a simple ping-pong test, which provides a certificate for the capability of the nodes to run certain multi-round protocols. We first show that in the noise-free regime the only way the nodes can pass the test is if they do indeed possess the desired capabilities. We then proceed to consider the case where operations are noisy, and provide an initial analysis showing how our test can be used to estimate parameters that allow us to draw conclusions about the actual performance of such protocols on the tested nodes. Finally, we investigate the tightness of this analysis using example cases in a numerical simulation.

description: The spectacular expansion of the Internet has led to the development of a new research problem in the field of natural language processing: automatic toxic comment detection, since many countries prohibit hate speech in public media. There is no clear and formal definition of hate, offensive, toxic and abusive speeches. In this article, we put all these terms under the umbrella of "toxic" speech. The contribution of this paper is the design of binary classification and regression-based approaches aiming to predict whether a comment is toxic or not. We compare different unsupervised word representations and different DNN based classifiers. Moreover, we study the robustness of the proposed approaches to adversarial attacks by adding one (healthy or toxic) word. We evaluate the proposed methodology on the English Wikipedia Detox corpus. Our experiments show that using BERT fine-tuning outperforms feature-based BERT, Mikolov's and fastText representations with different DNN classifiers.

Scopaeus kokodanus Cameron, 1938: 144, 155
Specimens examined (Papua New Guinea): Holotype ♀, Oro Prov., Kokoda, labelled as follows: ‘Type’ (round label edged in red), ‘PAPUA, Kokoda. 1,200ft. vi-vii.1933. L. E. Cheesman. B.

FRISCH 2022’ (NHML) [Cameron (1938: 144, 145) described S. kokodanus after a ‘unique’ specimen. Thus, the type specimen is a holotype by monotypy (ICZN 1999: Article 73.1.1.)]; 1 ♀, Ehi Prov., Onerunka: Namu River, 01.12.1979, leg. Ullrich (MHNG); 1♀, same locality and collector, but 30.05.1979 (MFNB); 1♀, Morobe Prov., Morobe Mts: Waritaian (correct spelling?), 06.1979, leg. Ullrich (MHNG).
Diagnosis: Body shape and coloring as in Fig. 1. Total body length 4.6 – 4.7 mm; forebody length 2.8 – 2.9 mm. Head pyriform, 1.13 – 1.15 (Ø 1.14) times as long as wide, across eyes 1.31 – 1.35 (Ø 1.34) times as wide as across tempora at half of their length from eyes to neck constriction. Eyes 0.5 – 0.53 (Ø 0.52) times as long as tempora. Elytra about 1.1 times as long as pronotum. Penultimate segment of antenna about 1.1 times as long as wide. Tibia of mesothoracic leg 7.7 – 8.8 (Ø 8.5) times as long as wide. Body black-brown except for yellow margin in posterior seventh of elytra, dark brown maxillary palpi with light brown apical third of last segment, dark brown legs with medium brown tarsi, and antennae becoming evenly lighter from dark brown proximal segments towards light brown apical segments.
Male unknown.
Distribution: Scopaeus kokodanus is hitherto known from the Oro and Ehi provinces in southeastern Papua New Guinea only.
Comparative notes: Within the Scopaeus kokodanus species group, S. kokodanus (Fig. 1) agrees with Scopaeus arfakmonium (Fig. 2) in the large body size and the pyriform head, but differs by the absence of a yellow posterior margin of the elytra. Scopaeus balkei (Fig. 3) and S. potamides (Fig. 4) are easily distinguished by smaller size and the non-pyriform head. Scopaeus kokodanus moreover has shorter distal antennomeres than the related species with the penultimate segment almost square.
Comment: According to Evenhuis (2003: 48), the ‘Annals and Magazine of Natural History, Volume III, Eleventh Series, 1939’ with the article in which Malcolm Cameron described Scopaeus kokodanus was published December 31, 1938, which is why the year of description of the species is 1938.

Goodness-of-Fit Tests based on Series Estimators in Nonparametric Instrumental Regression

Publisher: name: arXiv
Year: 2019
Subjects: subject: Econometrics (econ.EM)
subject: FOS: Economics and business

description: This paper proposes several tests of restricted specification in nonparametric instrumental regression. Based on series estimators, test statistics are established that allow for tests of the general model against a parametric or nonparametric specification as well as a test of exogeneity of the vector of regressors. The tests' asymptotic distributions under correct specification are derived and their consistency against any alternative model is shown. Under a sequence of local alternative hypotheses, the asymptotic distributions of the tests is derived. Moreover, uniform consistency is established over a class of alternatives whose distance to the null hypothesis shrinks appropriately as the sample size increases. A Monte Carlo study examines finite sample performance of the test statistics.

description: In Durango State, Mexico, the production of beans is usually performed under adverse condition including: use of expensive and polluting chemical fertilizers, agriculture lands poor in organic material and erratic rainfall conditions. All this adversely affects the environment, the physical and economic returns and which expression is a low standard of living of farmers. To assist in improving these conditions and reduce environmental damage, this study was implemented with the aim of analyzing the economic feasibility of the use of mycorrhiza (Glomus Intraradices)and chemical fertilizer on beans (Phaseolus vulgaris L.) under rainfed conditions, in the spring-summer seasons of 2008 and 2009. The transfer of technology was done by researchers of the National Institute of Forestry, Agricultural and Livestock Research (INIFAP) - Valle del Guadiana and productions was in direct seeding with producers under their own productions system. The evaluation was carried out in the municipalities of Guadalupe Victoria,Cuencame, Peñon Blanco and Panuco de Coronado of the Durango state, Mexico. In the economic evaluation the methodology known as "Partial Budget" of CIMMYT was used. The results indicate that mycorrhizal fertilization practices are recommended for rainfed bean producers because the benefits outweight the costs incurred by doubling the rates of return.

description: Canonical transformation plays a fundamental role in simplifying and solving classical Hamiltonian systems. We construct flexible and powerful canonical transformations as generative models using symplectic neural networks. The model transforms physical variables towards a latent representation with an independent harmonic oscillator Hamiltonian. Correspondingly, the phase space density of the physical system flows towards a factorized Gaussian distribution in the latent space. Since the canonical transformation preserves the Hamiltonian evolution, the model captures nonlinear collective modes in the learned latent representation. We present an efficient implementation of symplectic neural coordinate transformations and two ways to train the model. The variational free energy calculation is based on the analytical form of physical Hamiltonian. While the phase space density estimation only requires samples in the coordinate space for separable Hamiltonians. We demonstrate appealing features of neural canonical transformation using toy problems including two-dimensional ring potential and harmonic chain. Finally, we apply the approach to real-world problems such as identifying slow collective modes in alanine dipeptide and conceptual compression of the MNIST dataset.

description: A pollution tax or emissions trading scheme places a price on greenhouse gas emissions. This price also is an additional indirect tax and a government revenue windfall. To restore distributional equity, to avoid compounding the efficiency costs of existing distorting taxes and to maintain macroeconomic stability, it is argued that most of the revenue windfall be recycled to households as lower income tax rates and higher social security payments. As the carbon price rises over time, new and larger tax mix change packages will be required.

description: We present a nonperturbative QCD calculation of elastic $J/ψ$ meson production in photon-proton scattering at high energies. Using light cone wave functions of the photon and vector mesons, and the framework of the model of the stochastic QCD vacuum, we calculate the differential and integrated elastic cross sections for $γp \goto J/ψp $ . With an energy dependence following the two-pomeron model we are able to give a consistent description of the integrated cross sections and the differential cross sections at low $|t|$ in the range from 20 GeV up to the highest HERA energies. We discuss different approaches to introduce saturation and find no specific effects up to energies presently available. We also calculate and compare to experiments the cross section for $\upsilon$ photoproduction.

description: We prove two results about vector bundles on singular algebraic surfaces. First, on proper surfaces there are vector bundles of rank two with arbitrarily large second Chern number and fixed determinant. Second, on separated normal surfaces any coherent sheaf is the quotient of a vector bundle. As a consequence, for such surfaces the Quillen K-theory of vector bundles coincides with the Waldhausen K-theory of perfect complexes. Examples show that, on nonseparated schemes, usually many coherent sheaves are not quotients of vector bundles.

description: Considering a Skyrme model with a peculiar gauging of the symmetry, monopole-like solutions exist through a topological lower bound. However, it was recently shown that these objects cannot form bound states in the limit of vanishing Skyrme coupling. Here we consider these monopoles in scalar-tensor gravity. A numerical study of the equations reveals that neither the coupling to gravity nor to the scalar dilaton nor to dilaton-gravity leads to bound multimonopole states.

description: The nonnegativity of the CR Paneitz operator plays a crucial role in three-dimensional CR geometry. In this paper, we prove this nonnegativity for embeddable CR manifolds. This result and previous works give an affirmative solution of the CR Yamabe problem for embeddable CR manifolds. We also show the existence of a contact form with zero CR $Q$-curvature, and generalize the total $Q$-prime curvature to embeddable CR manifolds with no pseudo-Einstein contact forms. Furthermore, we discuss the logarithmic singularity of the Szegő kernel.

description: We investigate a plausible route to resolving the black hole information paradox by examining the effects of decoherence on Hawking radiation. In particular, we show that a finite but non-zero rate of decoherence can lead to efficient extraction of information from the evaporating black hole. This effectively pushes the paradox from becoming manifest at the Page time when the black hole has evaporated to half its size, to a timescale solely determined by the rate of decoherence. If this rate is due to a putative interaction with gravitons, the black hole at this timescale can be expected to be Planck-sized, but notably without an extensive amount of information packed inside. We justify our findings by numerically studying a toy model of stabilizer circuits that can efficiently model black hole evaporation in the presence of decoherence. The latter is found to be well described by an effective rate equation for the entanglement and which corroborates our findings.

description: The Agricultural Act of 2014 solidified insurance as the cornerstone of U.S. agricultural policy. The Congressional Budget Office (2014) estimates this Act will increase spending on agricultural insurance programs by $5.7 billion to a total of $89.8 billion over the next decade. In light of the sizable resources directed toward these programs, accurate rating of insurance contracts is of utmost importance to producers, private insurance companies, and the federal government. Unlike most forms of insurance -- where sufficient information exists to accurately estimate the probability and magnitude of losses (i.e. the underlying density) -- agricultural insurance is plagued by a paucity of spatially correlated data. A novel interpretation of Bayesian Model Averaging is used to estimate a set of possibly similar densities that offers greater efficiency if the set of densities are similar while seemingly not losing any if the set of densities are dissimilar. Simulations indicate finite sample performance -- in particular small sample performance -- is quite promising. The proposed approach does not require knowledge of the form or extent of any possible similarities, is relatively easy to implement, admits correlated data, and can be used with either parametric or nonparametric estimators. We use the proposed approach to estimate U.S. crop insurance premium rates for area-type programs and develop a test to evaluate its efficacy. An out-of-sample game between private insurance companies and the federal government highlights the policy implications for a variety of crop-state combinations. We repeat the empirical analyses under reduced sample sizes given: (i) new programs will dramatically expand area-type insurance to crops and states that have significantly less historical data; and (ii) changes in technology could render some historical loss data no longer representative. Consistent with the simulation results, the performance of the proposed approach with respect to rating area-type insurance -- in particular small sample performance -- remains quite promising.

description: Neuropsychiatric disorders such as major depressive disorder (MDD) arise from a complex set of genetic and environmental factors. The serotonin transporter (SERT) is a key regulator of synaptic serotonin (5-HT), and its inhibition is an important pharmacological target for treating MDD. The SERT-linked polymorphic region (5-HTTLPR) contains two major variants (short and long) that have been implicated in modulating susceptibility to MDD by altering the level of expression of SERT. Both variants contain C-rich repeats that conform to consensus i-motif folding sequences. i-Motifs are quadruplex DNA structures that have been proposed to have a role in transcription regulation. With spectroscopic techniques, we demonstrate that both alleles are able to form i-motifs at acidic pH, and at neutral pH under conditions of molecular crowding. This highlights the potential for i-motif formation to contribute to transcriptional regulation of the serotonin transporter, with a potential role in the pathophysiology of neuropsychiatric disorders.

description: In this work, we present a 3D Phase Field Dislocation Dynamics (PFDD) model for body-centered cubic (BCC) metals. The model formulation is extended to account for the dependence of the Peierls barrier on the line-character of the dislocation. Simulations of the expansion of a dislocation loop belonging to the $\left\{110\right\} \left<111\right>$ slip system are presented with direct comparison to Molecular Statics (MS) simulations. The extended PFDD model is able to capture the salient features of dislocation loop expansion predicted by MS simulations. The model is also applied to simulate the motion of a straight screw dislocation through kink-pair motion.

description: As in previous studies on traditional media, previous work has assumed that online and offline advertising are substitutes. However, empirical evidence for this premise is lacking. This paper investigates the substitution between online advertising and offline advertising as well as the impact of the introduction of new media technology on the cost of advertising. Using a rich dataset of monthly observations for 52 carbonated soft drink brands between 2005 and 2011, we estimate a translog cost function that considers the mix of on/off line advertising and online advertising adoption at the brand level. As in previous work, we find that TV and print media are close substitutes. Surprisingly, however, we find that online advertising is a complement to rather than a substitute for both TV and print media advertising. This might be explained by online advertising’s targeting younger market segments and acting as a reinforcement of TV and print media advertising exposure. Further results show that the adoption of online advertising has lowered the cost of advertising for achieving a sales target but that its role as a complement rather than a substitute is weakening.
Compressible MHD Turbulence in Interstellar Plasmas

description: Radio-wave scintillation observations reveal a nearly Kolmogorov spectrum of density fluctuations in the ionized interstellar medium. Although this density spectrum is suggestive of turbulence, no theory relevant to its interpretation exists. We calculate the density spectrum in turbulent magnetized plasmas by extending the theory of incompressible MHD turbulence given by Goldreich & Sridhar to include the effects of compressibility and particle transport. Our most important results are as follows. (1) Density fluctuations are due to the slow mode and the entropy mode. Both modes are passively mixed by the cascade of shear Alfven waves. Since the shear Alfven waves have a Kolmogorov spectrum, so do the density fluctuations. (2) Observed density fluctuation amplitudes imply either that the magnetic and gas pressures are comparable, or that the outer scale of the turbulence is very small. (3) A high degree of ionization is required for the cascade to survive damping by neutrals and thereby to extend to small lengthscales. Regions that are insufficiently ionized produce density fluctuations only on lengthscales larger than the neutral damping scale. These regions may account for the excess of power that is found on large scales. (4) Both the entropy mode and the slow mode are damped on lengthscales below that at which protons can diffuse across an eddy during the eddy's turnover time. Consequently, eddies whose extents along the magnetic field are smaller than the proton collisional mean free path do not contribute to the density spectrum. However, in MHD turbulence eddies are highly elongated along the magnetic field. From an observational perspective, the relevant lengthscale is that transverse to the magnetic field. Thus the cut-off lengthscale for density fluctuations is significantly smaller than the proton mean free path.
