description: There has been significant shifts in both international and domestic demand for U.S tree nuts over the past decade with potentially mixed effects for U.S producers and consumers. This paper investigates short run and long run dynamics in the domestic demand for six brands of tree nuts (pecan, almonds, walnuts, macadamias, pistachios and hazelnuts) using annual time series data for utilization and value. A static and a dynamic Almost Ideal Demand system (AIDS) was estimated with Seemingly Unrelated Regression. We analyzed consumers responsiveness to price and expenditure using parameters derived from the model

description: Beta agonists are feed additives that increase the efficiency of feed conversion in feedlot cattle. Their use has recently generated significant discussion. We have developed an equilibrium displacement model that examines the impact of their removal from the market on production and prices of beef at the farm, wholesale, and retail levels. After their removal beef prices are increased in the retail, wholesale, feedlot, and cow/calf segments. Quantity of beef available decreases initially and in the long-term in the retail, wholesale, and feedlot segments, but increases in the long-term. Quantity produced increases in the short and long term for the cow/calf segment.

description: This paper is an analysis of the BLM’s internet auctions for wild horses and Burros from November 2012 through March 2013. This study uses the Hedonic pricing model to determine the magnitude in terms of demand elasticity at which physical characteristics of each horse influences buyers’ decisions to bid for a horse. OLS regressions are run and compared where physical characteristics of wild horses and burros are the independent variables and the winning bid price of horses is the dependent variable. The most statistically significant physical characteristics from the most appropriate OLS regression model are identified for the purpose of increasing the public adoption rates.The highly desirable physical qualities of wild horses and burros are identified to be the proximity of a bidder to sale location, horses that are captured out of BLM’s holding facility, a horse that is a mare or stallion, a colored horse and a horse with a unique quality such as pinto. Sterilization of horses in the BLM’s holding facility is a significant way of increasing public adoption rates and controlling the population of wild horses.

Exceptional points in dissipatively coupled spin dynamics

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)
subject: FOS: Physical sciences

description: We theoretically investigate dynamics of classical spins exchange-coupled through an isotropic medium. The coupling is treated at the adiabatic level of the medium's response, which mediates a first-order in frequency dissipative interaction along with an instantaneous Heisenberg exchange. The resultant damped spin precession yields exceptional points (EPs) in the coupled spin dynamics, which should be experimentally accessible with the existing magnetic heterostructures. In particular, we show that an EP is naturally approached in an antiferromagnetic dimer by controlling local damping, while the same is achieved by tuning the dissipative coupling between spins in the ferromagnetic case. Extending our treatment to one-dimensional spin chains, we show how EPs can emerge within the magnonic Brillouin zone by tuning the dissipative properties. The critical point, at which an EP pair emerges out of the Brillouin zone center, realizes a gapless Weyl point in the magnon spectrum. Tuning damping beyond this critical point produces synchronization (level attraction) of magnon modes over a finite range of momenta, both in ferro- and antiferromagnetic cases. We thus establish that damped magnons can generically yield singular points in their band structure, close to which their kinematic properties, such as group velocity, become extremely sensitive to the control parameters.

description: We speculate that the universe is filled with stars composed of electromagnetic and dilaton fields which are the sources of the powerful gamma-ray bursts impinging upon us from all directions of the universe. We calculate soliton-like solutions of these fields and show that their energy can be converted into a relativistic plasma in an explosive way. As in classical detonation theory the conversion proceeds by a relativistic self-similar solution for a spherical detonation wave which extracts the energy from the scalar field via a plasma in the wave front.

Loop quantum cosmological dynamics of scalar-tensor theory in the Jordan frame
Creators: name: Han, Yu
Publisher: name: arXiv
Year: 2019
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: The effective dynamics of scalar-tensor theory (STT) in the Jordan frame is studied in the context of loop quantum cosmology with holonomy corrections. After deriving the effective Hamiltonian from the connection dynamics formulation, we obtain the holonomy-corrected evolution equations of STT on spatially flat Friedmann-Robterson-Walker background, which exhibit some interesting features unique to the Jordan frame of STT. In particular, the linear term of the cosine function appearing in the equations could lead to dynamics much different from the classical theory in the low-energy limit. In the latter part of this paper, we choose a particular model in STT -- the Brans-Dicke theory to specifically illustrate these features. It is found that in Brans-Dicke theory the effective evolution equations can be classified into four different cases. Exact solutions of the Friedmann equation in terms of the internal time are obtained in these cases. Moreover, the solutions in terms of the proper time describing the late time evolution of the Universe are also obtained under certain approximation; in two cases the solutions coincide with the existing solutions in classical Brans-Dicke theory while in the other two cases the solutions do not.

description: In this paper we study a general nonlinear Schrödinger equation with a time dependent harmonic potential. Despite the lack of traslational invariance we find a symmetry trasformation which, up from any solution, produces infinitely many others which are centered on classical trajectories. The results presented here imply that, not only the center of mass of the wave-packet satisfies the Ehrenfest theorem and is decoupled from the dynamics of the wave-packet, but also the shape of the solution is independent of the behaviour of the center of the wave. Our findings have implications on the dynamics of Bose-Einstein condensates in magnetic traps

Some thermal properties of A-statistics are investigated under the assumption that the particles interact only via statistical interaction imposed by the Pauli principle of A-statistics. Apart from the general case, three particular examples are studied in more detail: (a) the particles have one and the same energy and chemical potential; (b) equidistant energy spectrum; (c) two species of particles with one and the same energy and chemical potential within each class. The grand partition functions and the average number of particles are among the thermodynamical quantities written down explicitly.

description: Repeating fast radio bursts (FRBs) present excellent opportunities to identify FRB progenitors and host environments, as well as decipher the underlying emission mechanism. Detailed studies of repeating FRBs might also hold clues to the origin of FRBs as a population. We aim to detect the first two repeating FRBs: FRB 121102 (R1) and FRB 180814.J0422+73 (R2), and characterise their repeat statistics. We also want to significantly improve the sky localisation of R2. We use the Westerbork Synthesis Radio Telescope to conduct extensive follow-up of these two repeating FRBs. The new phased-array feed system, Apertif, allows covering the entire sky position uncertainty of R2 with fine spatial resolution in one pointing. We characterise the energy distribution and the clustering of detected R1 bursts. We detected 30 bursts from R1. Our measurements indicate a dispersion measure of 563.5(2) pc cm$^{-3}$, suggesting a significant increase in DM over the past few years. We place an upper limit of 8% on the linear polarisation fraction of the brightest burst. We did not detect any bursts from R2. A single power-law might not fit the R1 burst energy distribution across the full energy range or widely separated detections. Our observations provide improved constraints on the clustering of R1 bursts. Our stringent upper limits on the linear polarisation fraction imply a significant depolarisation, either intrinsic to the emission mechanism or caused by the intervening medium, at 1400 MHz that is not observed at higher frequencies. The non-detection of any bursts from R2 implies either a highly clustered nature of the bursts, a steep spectral index, or a combination of both. Alternatively, R2 has turned off completely, either permanently or for an extended period of time.

description: Background: The mastic tree (formal name: Pistacia lentiscus var. Chia) is extensively cultivated on the southern part of the Greek island of Chios. Its extensive cultivation is due to the production of a special resin, known as mastic gum, or mastiha, which is widely used in several dietary, pharmaceutical and other products since ancient times. Mastic tree is an evergreen, dioecious (consisting of male and female individuals), woody plant. Furthermore, a number of morphological characteristics suggest the existence of several different plant groups, called here “morpho-varieties”, but it is probable that there exist an unknown number of different, deviating genotypes on the island. Nevertheless, five major morphologically determined morpho-varieties of mastic tree are mainly cultivated, namely “Votomos”, “Maroulitis”, “Mavroschinos”, “Stenophyllos” and “Fardyphyllos”. The morpho-varieties exhibit mostly, but not always, distinct morphology, on which their taxonomy was initially based. Since it is observed that different plant populations differ in the quantity and quality of the produced resin, it is important to explore whether these differences have a genetic basis, or are due to other factors, such as agricultural practices, or soil composition. To this end, the genetic diversity among these five morpho-varieties and within each one of them was investigated in the present study, using in a first approximation their Random Amplified Polymorphic DNA profiles and subsequently the sequence divergence of their Internal Transcribed Spacer regions 1 and 2. Results: The results confirm the existence of a considerable genotypic diversity among the five morpho-varieties studied and, furthermore, reveal the existence of genotypic diversity within each one of them, as well as the existence of a number of further deviating genotypes. The possibility, this diversity to be partly a result of reticulate evolution events is also discussed. Conclusions: This study provides evidence that the population of cultivated mastic trees on the island of Chios consists mainly of two species, i.e. Pistacia lentiscus and Pistacia x saportae, although it is clear that there also exist genetically deviating mastic trees, as well as individual plants, probably produced through hybridization between the two afore mentioned species.

description: With a total area of 210 squaremeters and about 15000 single silicon modules the silicon strip tracker of the CMS experiment at the LHC will be the largest silicon strip detector ever built. While the performance of the individual mechanical and electronic components has already been tested extensively, their interplay in larger integrated substructures also has to be studied before mass production can be launched, in order to ensure the envisaged performance of the overall system. This is the main purpose of the system tests, during which hardware components as final as possible are being integrated into substructures of the tracker subsystems. System tests are currently being carried out for all subsystems of the tracker. In addition, silicon modules and electronic components have been operated and studied in a particle beam environment. In this report results from the CMS silicon tracker system tests and a test beam experiment at CERN are presented.

description: Using the FDTD method, we investigate the electromagnetic propagation in two-dimensional photonic crystals, formed by parallel air cylinders in a dielectric medium. The corresponding frequency band structure is computed using the standard plane-wave expansion method. It is shown that within partial bandgaps, waves tend to bend away from the forbidden directions. This phenomenon perhaps need not be explained in terms of negative refraction or `superlensing' behavior, contrast to what has been conjectured.

description: In Hungary an increasing number of agricultural cooperatives have gone bankrupt or have broken up due to a lack of competitiveness under market conditions, in the aftermath of radical reforms. Others, however, have been able to maintain or even improve on previous levels of success. Individual farmers have also established new cooperatives and are working toward deepening cooperation. The paper discusses the importance of leadership of cooperatives during transition, a topic which is not well addressed in the literature. Production cooperatives are not only economic units, but also social networks. Two successful cooperatives in the same town, one old and one new, have been compared with respect to their social capital, development and leadership. The findings show that, in the traditional agricultural cooperative, a more social oriented leadership has helped to overcome economic, social, and psychological barriers arising during transition, while, in the case of the new co-op, improving cooperation has depended mainly on the increased level of social capital after the radical reforms.

Blue galaxies: modelling nebular He II emission in high redshift galaxies

Publisher: name: arXiv
Year: 2019
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Using cosmological simulations to make useful, scientifically relevant emission line predictions is a relatively new and rapidly evolving field. However, nebular emission lines have been particularly challenging to model because they are extremely sensitive to the local photoionization balance, which can be driven by a spatially dispersed distribution of stars amidst an inhomogeneous absorbing medium of dust and gas. As such, several unmodeled mysteries in observed emission line patterns exist in the literature. For example, there is some question as to why He II $λ4686$/H$β$ ratios in observations of lower-metallicity dwarf galaxies tend to be higher than model predictions. Since hydrodynamic cosmological simulations are best suited to this mass and metallicity regime, this question presents a good test case for the development of a robust emission line modeling pipeline. The pipeline described in this work can model a process that produces high He II $λ4686$/H$β$ ratios and eliminate some of the modeling discrepancy for ratios below 3% without including AGNs, X-ray binaries, high mass binaries, or a top-heavy stellar initial mass function. These ratios are found to be more sensitive to the presence of 15 Myr or longer gaps in the star formation histories than to extraordinary ionization parameters or specific star formation rates. This work also charts a path forward for the next generation of nebular emission line modeling studies.

Thorax, perforate or imperforate, with or without marginal teeth, not separated from the cephalis by regular collar pores. The rays of the internal spicule continue beyond the wall of the cephalis, and in and beyond the wall of the cephalis, and in and beyond the thoracic wall, as external spines” (Foreman 1963: 284).

Externally, more than four main spines, usually seven and only rarely five, two to four of which are incorporated in the pylome margin. A pylome net is sometimes present and in some species, and in some individuals of other species, it is considered that spicules are secondary lost.” (Holdsworth 1973: 122).

description: We present a new Riemannian metric, termed Log-Cholesky metric, on the manifold of symmetric positive definite (SPD) matrices via Cholesky decomposition. We first construct a Lie group structure and a bi-invariant metric on Cholesky space, the collection of lower triangular matrices whose diagonal elements are all positive. Such group structure and metric are then pushed forward to the space of SPD matrices via the inverse of Cholesky decomposition that is a bijective map between Cholesky space and SPD matrix space. This new Riemannian metric and Lie group structure fully circumvent swelling effect, in the sense that the determinant of the Fréchet average of a set of SPD matrices under the presented metric, called Log-Cholesky average, is between the minimum and the maximum of the determinants of the original SPD matrices. Comparing to existing metrics such as the affine-invariant metric and Log-Euclidean metric, the presented metric is simpler, more computationally efficient and numerically stabler. In particular, parallel transport along geodesics under Log-Cholesky metric is given in a closed and easy-to-compute form.

His results have been extended by Rosu, who employed techniques belonging to nonrelativistic supersymmetry to obtain time-dependent adiabatic indices. Further extensions are presented here using the known connection between the linear second-order differential equations and Dirac-like equations in the same supersymmetric context. These extensions are equivalent to adding an imaginary part to the adiabatic index which is proportional to the mass parameter of the Dirac spinor. The natural physical interpretation of the imaginary part is related to the particular dissipation and instabilities of the barotropic FRW hydrodynamics that are introduced by means of this supersymmetric scheme

description: Much of the discussion of decoherence has been in terms of a particle moving in one dimension that is placed in an initial superposition state (a Schrödinger "cat" state) corresponding to two widely separated wave packets. Decoherence refers to the destruction of the interference term in the quantum probability function. Here, we stress that a quantitative measure of decoherence depends not only on the specific system being studied but also on whether one is considering coordinate, momentum or phase space. We show that this is best illustrated by considering Wigner phase space where the measure is again different. Analytic results for the time development of the Wigner distribution function for a two-Gaussian Schrodinger "cat" state have been obtained in the high-temperature limit (where decoherence can occur even for negligible dissipation) which facilitates a simple demonstration of our remarks.

description: This paper provides insights of the Italian farmers' markets (FMs) experience. These short food chains can be conceptualized among the so-called "alternative agro-food networks", which reject the traditional food chains features - productivity, products standardization and industrial organization - to focus on other issues such as quality, local production and "naturality" of agro-food production. The main objective of the paper is to evaluate the sustainability of FMs, through the analysis of the demand and the supply side. The analysis is based on a survey administered in 13 Italian FMs, involving 158 farmers and 458 consumers. Data are used to evaluate consumers' demand for sustainability within FMs and sustainability indicators at the farm level. These indicators support a classification of the farms, aimed at analysing their motivation to participate in the markets and the extent to which they are able to meet consumers' demand. Results show that FMs might be able to favour the spreading of a more sustainable economy. However, farms should improve their business strategies in order to meet consumers' demand for sustainability. In this respect, agricultural policies at the European and local level can play a role, in order to enhance sustainable practices within the farms.

description: We systematically construct derivative self-interactions for massless and massive 2-forms. There exists a no-go theorem in the literature for constructing Galileon-like Lagrangians in four dimensions for the 2-form with gauge invariance, the Kalb-Rammond field. The presence of non-minimal couplings strongly relies on the contraction with divergenceless tensors. In four dimensions these are the Einstein tensor and the double dual Riemann tensor. Even though they are divergenceless on their own, their combination ceases to be. In the case of massless 2-forms we are not able to establish non-minimal couplings of the 2-form to the gravity sector with second order equations of motion due to the impossibility of building consistent combinations of divergenceless tensors. Using the systematical construction in terms of the Levi-Civita tensor, we aim at constructing Galileon-like derivative self-interactions for the massive 2-form. Apart from $L_2$ and $L_4$ we are not able to construct further Galileon-like Lagrangians. For the massive case, an important non-minimal coupling between the 2-form and the double dual Riemann tensor arises, which receives additional support from the decoupling limit. Promoting the interactions in $L_4$ requires the presence of appropriate non-minimal couplings and we give concrete examples for this.

description: Uncovering the heterogeneity of cell populations is a long-standing goal in fields ranging from antimicrobial resistance to cancer research. Emerging technology platforms such as droplet microfluidics hold the promise to decipher cellular heterogeneity at ultra-high-throughput. However, there is a lack of methods able to rapidly identify and isolate single cells or 3D cell cultures. Here we demonstrate that deep neural networks can accurately classify single droplet images in real-time based on the presence and number of micro-objects including single mammalian cells and multicellular spheroids. This approach also enables the identification of specific objects within mixtures of objects of different types and sizes. The training sets for the neural networks consisted of several hundred images manually picked and augmented to up to thousands of images per training class. Training required less than 10 minutes using a single GPU, and yielded accuracies of over 90% for single mammalian cell identification. Crucially, the same model could be used to classify different types of objects such as polystyrene spheres, polyacrylamide beads and MCF-7 cells. We applied the developed method to the selection of 3D cell cultures generated with Hek293FT cells encapsulated in agarose gel beads, highlighting the potential of the technology for the selection of objects with high diversity of visual appearance. The real-time sorting of single droplets was in-line with droplet generation and occurred at rates up to 40 per second independently of image size up to 480 x 480 pixels. The presented microfluidic device also enabled storage of sorted droplets to allow for downstream analyses.

description: The importance of eco-innovations for industry has been rising exponentially in recent years. However, even if recent trends show that firms are increasingly committed to eco-innovations, there is little knowledge on why and how companies integrate environmental sustainability into new product development. In this paper we offer a comprehensive analysis of the drivers of eco-innovation in the Italian wine industry on the basis of a large survey on Italian wine producers. We analyse the impact of firms’ characteristics and their technological and organizational capabilities on the introduction of eco-innovations. The relevance of the drivers in influencing the probability of introducing eco-innovations is measured with a latent class econometric model. Our evidence shows that business characteristics and firms’ scientific search processes and their general innovative behaviour are key drivers of eco-innovation. Therefore, according to our results, firms’ commitment to eco-innovate does not differ substantially from other types of innovation activities.

description: disease and stroke which, as well as individual pain and suffering and shortened life, create a burden for the state in the form of health care costs and lost economic production; diseases linked to overweight and obesity account for around 5% of total health care costs in Europe, and at least as much again in lost economic production. In this context it is no surprise that healthy eating has become a major public health concern, prompting many European Member States to take measures to improve their citizens’ diets. Neither is it a surprise that governments are at least paying lip-service to a desire that their interventions should be evidence-based, meaning there should be evidence that they are effective and cost effective. Probably, though less explicitly stated, politicians would like evidence that interventions will be acceptable to the public. These wishes are more complex than appears at first sight.

description: A Green's function approach is presented for the D-dimensional inverse square potential in quantum mechanics. This approach is implemented by the introduction of hyperspherical coordinates and the use of a real-space regulator in the regularized version of the model. The application of Sturm-Liouville theory yields a closed expression for the radial energy Green's function. Finally, the equivalence with a recent path-integral treatment of the same problem is explicitly shown.

Unloaded Geometry

description: Individualized computer models of the geometry of the human heart are often based on magnetic resonance images (MRI) or computed tomography (CT) scans. The stress distribution in the imaged state cannot be measured but needs to be estimated from the segmented geometry, e.g. by an iterative algorithm. As the convergence of this algorithm depends on different geometrical conditions, we systematically studied their influence. Beside various shape alterations, we investigated the chamber volume, as well as the effect of material parameters. We found a marked influence of passive material parameters: increasing the model stiffness by a factor of ten halved the residual norm in the first iteration. Flat and concave areas led to a reduced robustness and convergence rate of the unloading algorithm. With this study, the geometric effects and modeling aspects governing the unloading algorithm's convergence are identified and can be used as a basis for further improvement.
