description: County-level data for 11 southern states for 1980 and 2000 are used to examine income convergence. Ordinary least squares regression of logarithmic difference on average per capita income in 1980 demonstrated conditional income convergence with higher income changes in counties with smaller initial populations, smaller changes in African Americans, employment, education, age structure, travel time to work, or dependent age populations. The estimated rate of income convergence was 3.82% per year.

description: Positive semidefinite matrix factorization (PSDMF) expresses each entry of a nonnegative matrix as the inner product of two positive semidefinite (psd) matrices. When all these psd matrices are constrained to be diagonal, this model is equivalent to nonnegative matrix factorization. Applications include combinatorial optimization, quantum-based statistical models, and recommender systems, among others. However, despite the increasing interest in PSDMF, only a few PSDMF algorithms were proposed in the literature. In this work, we provide a collection of tools for PSDMF, by showing that PSDMF algorithms can be designed based on phase retrieval (PR) and affine rank minimization (ARM) algorithms. This procedure allows a shortcut in designing new PSDMF algorithms, as it allows to leverage some of the useful numerical properties of existing PR and ARM methods to the PSDMF framework. Motivated by this idea, we introduce a new family of PSDMF algorithms based on iterative hard thresholding (IHT). This family subsumes previously-proposed projected gradient PSDMF methods. We show that there is high variability among PSDMF optimization problems that makes it beneficial to try a number of methods based on different principles to tackle difficult problems. In certain cases, our proposed methods are the only algorithms able to find a solution. In certain other cases, they converge faster. Our results support our claim that the PSDMF framework can inherit desired numerical properties from PR and ARM algorithms, leading to more efficient PSDMF algorithms, and motivate further study of the links between these models.

description: We report the observation of a near-threshold enhancement in the omega-J/psi invariant mass distribution for exclusive B-->K omega J/psi decays. The results are obtained from a 253 fb-1 data sample that contains 275 million BB-bar meson pairs that were collected near the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric energy e+e- collider. The statistical significance of the omega-J/psi mass enhancement is estimated to be greater than 8 sigma.

description: The Bloch-Torrey equation governs the evolution of the transverse magnetization in diffusion magnetic resonance imaging, where two mechanisms are at play: diffusion of spins (Laplacian term) and their precession in a magnetic field gradient (imaginary potential term). In this paper, we study this equation in a periodic medium: a unit cell repeated over the nodes of a lattice. Although the gradient term of the equation is not invariant by lattice translations, the equation can be analyzed within a single unit cell by replacing a continuous-time gradient profile by narrow pulses. In this approximation, the effects of precession and diffusion are separated and the problem is reduced to the study of a sequence of diffusion equations with pseudo-periodic boundary conditions. This representation allows for efficient numerical computations as well as new theoretical insights into the formation of the signal in periodic media. In particular, we study the eigenmodes and eigenvalues of the Bloch-Torrey operator. We show how the localization of eigenmodes is related to branching points in the spectrum and we discuss low- and high-gradient asymptotic behaviors. The range of validity of the approximation is discussed; interestingly the method turns out to be more accurate and efficient at high gradient, being thus an important complementary tool to conventional numerical methods that are most accurate at low gradients.

description: In order to avoid costly data collection practices common in hedonic valuation of aesthetic amenities, easy-to-collect secondary County tax and geospatial data are used to derive estimates for spatial effects on residential land values. Three Georgia Counties were selected due to data availability: Clarke, Henry, and Richmond. All properties meeting panel-design criterion are included in analysis samples. Large datasets prompt the omission of traditional hedonic model variables such as property characteristics. The focus of analysis is directed toward Canopy and Impervious land-cover estimates. Focal means are calculated at different ranges for immediate and neighborhood-wide assessment of surrounding cover. Community variables designed to describe neighborhood composition are included. Class, the measure of average size and Density, the average distance between nearby homes, are calculated at same neighborhood ranges as Focal means. Regressors also include distances to Schools, Hospitals, Airports, and Highways. Pooled Ordinary Least Squares performed with data normalized by log-transformation yields practical, statistically significant results. Consistency of estimates among Counties provides assurance of model viability, while variety is still strong between all Counties. Some concerns of data reliability and appropriateness of goodness-of-fit measure are voiced for any future analysis.

description: Top quark pair production by (polarized) gamma gamma collisions offers an interesting testing ground of the Standard Model and its extensions. In this Letter we present results for differential cross sections of top quark pair production and decay including QCD radiative corrections. We take into account the full dependence on the top quark spins. We give analytic and numerical results for single and double differential angular distributions of t tbar decay products which are due to top quark polarizations and spin correlations in the intermediate state.

description: Understanding the galaxy-halo connection is fundamental for contemporary models of galaxy clustering. The extent to which the haloes' assembly history and environment impact galaxy clustering (a.k.a. galaxy assembly bias; GAB), remains a complex and challenging problem. Using a semi-analytic galaxy formation model, we study the individual contributions of different secondary halo properties to the GAB signal. These are obtained by comparing the clustering of stellar-mass selected samples to that of shuffled samples where the galaxies are randomly reassigned to haloes of fixed mass and a specified secondary halo property. We explore a large range of internal halo properties and environmental measures. We find that commonly used properties like halo age or concentration amount to only 20-30 per cent of the signal, while the smoothed matter density or the tidal anisotropy can account for the full level of GAB (though care should be given to the specific definition). For the "successful" measures, we examine the occupancy variations and the associated changes in the halo occupation function parameters. These are used to create mock catalogues that reproduce the full level of GAB. Finally, we propose a practical modification of the standard halo occupation distribution model, which can be tuned to any level of assembly bias. Fitting the parameters to our semi-analytic model, we demonstrate that the corresponding mock catalogue recovers the target level of GAB as well as the occupancy variations. Our results enable producing realistic mock catalogues and directly inform theoretical modelling of assembly bias and attempts to detect it in the Universe.

description: Drone teleoperation is usually accomplished using remote radio controllers, devices that can be hard to master for inexperienced users. Moreover, the limited amount of information fed back to the user about the robot's state, often limited to vision, can represent a bottleneck for operation in several conditions. In this work, we present a wearable interface for drone teleoperation and its evaluation through a user study. The two main features of the proposed system are a data glove to allow the user to control the drone trajectory by hand motion and a haptic system used to augment their awareness of the environment surrounding the robot. This interface can be employed for the operation of robotic systems in line of sight (LoS) by inexperienced operators and allows them to safely perform tasks common in inspection and search-and-rescue missions such as approaching walls and crossing narrow passages with limited visibility conditions. In addition to the design and implementation of the wearable interface, we performed a systematic study to assess the effectiveness of the system through three user studies (n = 36) to evaluate the users' learning path and their ability to perform tasks with limited visibility. We validated our ideas in both a simulated and a real-world environment. Our results demonstrate that the proposed system can improve teleoperation performance in different cases compared to standard remote controllers, making it a viable alternative to standard Human-Robot Interfaces.

description: Recent social spending inflation in China has led to its growth rate far exceeding that of income and other consumption. In this paper, we estimate private returns to social spending, such as higher social status and larger social network that serve as certain functions. In almost all specifications we find that gift spending has significant private returns, but the returns are biased towards richer households. Upon comparing different measures of centrality, we also find that social connections are more accurately characterized when weighted by their intensities (values), capturing their role in mobilizing scarce resource in the network. Furthermore, social status and network may change long-term income trajectory and the resulted consumption. However, our findings do not suggest that they are vehicles through which they could facilitate smoother consumption against shocks. The result does not depend on how heterogeneous the shocks are.

description: In agricultural policy in Germany institutional and functional spheres of responsibility are mixed. The constitution of the Federal Republic of Germany warrants a strong position to the federal states in relation to the federal government. But in fact, the decentralized lines of the constitutional law and the clear division of responsibilities between the federal government and the federal states have lost their contours over time. Taking the developments on the revenue side and the expenditure side together, in the national sphere in Germany there is the impression that the various governmental levels form a sturdy “network”. Only at the level of implementation there are quite pronounced decentralized elements. There has been much critical discussion since the late 1970s of this co-operative federalism, the result of the networking of government levels. However, it has not been changed in principle. In the field of agricultural policy this networking is superimposed by the incorporation of the EU. Against the background of changed underlying conditions for integration and increased integration of European agriculture in world trade, the extensive transfer of agricultural policy responsibilities to the EU is in need of revision. In particular, the opening of the EU towards Central and Eastern Europe also requires a consideration of the mechanism of the EU agricultural policy. Recommendations from the viewpoint of fiscal federalism are discussed for a revision in competences and clear demarcation of responsibilities for different fields of agricultural policy.

description: During coalescence of liquid drops contacting a solid, the liquid sweeps wetted and solid-projected areas. The extent of sweeping dictates the performance of devices such as self-cleaning surfaces, anti-frost coatings, water harvesters, and dropwise condensers. For these applications, weakly- and non-wetting solid substrates are preferred as they enhance drop dynamical behavior. Accordingly, our coalescence studies here are restricted to drops with contact angle 90° $\le θ_{0} \le$ 180°. Binary sessile drop coalescence is the focus, with volume of fluid simulations employed as the primary tool. The simulations, which incorporate a Kistler dynamic contact angle model, are first validated against three different experimental substrate systems and then used to study the influence of solid wettability on sweeping by modifying $θ_{0}$. With increasing $θ_{0}$ up to 150°, wetted and projected swept areas both increase as drop center of mass heightens. For $θ_{0} \ge$ 150°, coalescence-induced drop jumping occurs owing to the decreasing wettability of the substrate and a focusing of liquid momentum due to the symmetry-breaking solid. In this regime, projected swept area continues to increase with $θ_0$ while wetted swept area reaches a maximum and then decreases. The sweeping results are interpreted using the mechanical energy balance from hydrodynamic theory and also compared to free drop coalescence.

description: This study evaluates both the profitability and risk efficiency of grazing stocker steers on conservation tillage winter wheat pasture using simulation and stochastic efficiency with respect to a function (SERF). Average daily gains are simulated for steers grazed on conventional tillage (CT), reduced tillage (RT) and no-till (NT) winter wheat pasture. Steer price distributions and prices for key production inputs such as diesel, fertilizer, and glyphosate are also simulated. Stocker steer net return distributions by tillage treatment are constructed and ranked for risk efficiency using SERF. The results indicate the NT system is the most profitable and most risk efficient of the three tillage systems, followed by the RT system. Both conservation tillage systems dominate the CT system under risk aversion based on SERF analysis and generate positive risk premiums for risk-averse cattle producers above the CT system.

description: The relationship between appreciation of the exchange rate and employment is investigated in the period 1980-2008 for the United States. Previous literature has found a negative relationship, studying as channels of transmission the role of exports, substitution of factors of production, terms of trade, openness, and productivity. This study endeavors to shed some light on the role of government debt on determining the level of employment through the exchange rate. The mechanism of transmission is defined. The model is derived from a standard Cobb Douglas production function having government debt affecting the growth of productivity. Exchange rate appreciations and increasing public debt were found to be detrimental to employment.

We first present a theoretically estimated low-temperature entropy and compare it with numerical results. Then, we consider the mapping between this model and the three-colour problem, i.e.,colouring a regular graph with coordination equal to 4 (a two-dimensional lattice) with three colours, for which we apply the transfer-matrix method to calculate all allowed configurations for two-dimensional square lattices of $N$ oxygen atoms ranging from 4 to 225. Finally, from a linear regression of the transfer matrix results, we obtain an estimate for the case $N\rightarrow \infty $ which is compared with the exact solution by Lieb.

However, not all of these FMD-affected countries adopted the same treatment policy to ease domestic FMD issues. This study proposes a gravity model with fixed-effect regressions to analyze the effects of FMD in countries that import U.S. swine meat. Annual trade data for seventeen countries are used in this study. This study confirms that different policies change the results from FMD. FMD-affected countries which adopted a vaccination policy have negative impacts on U.S. swine meat exports, and the estimated results did confirm that these seven countries are still very important swine meat markets for the U.S.

description: Forestry functions of Danzhai County are introduced from the aspects of physical production value, social service value and ecological service value. Quantitative research on monetary value of the functions is conducted by using the Replacement Cost Method (RCM), Classification Valuation Method (CVM) and Travel Cost Method (TCM). Result shows that the value of forestry production is 19712.6 thousand yuan, the value of flood control and water conservation is 111000 thousand yuan, which is 5.63 times of forestry production value. Besides, the value of soil conservation and yield increase is 160101.5 thousand yuan, which is 8.12 times of the value of forestry production; the value of carbon fixation and oxygen release and air purification is 11 26624.1 thousand yuan, 57.15 times of the value of forestry production; and the value of the employment and income increase, and the landscape and recreation is 5380 thousand yuan, which is 0.27 times of the value of forestry production. Due to the important external role of the forestry, government should take into account the multifunction of forestry when making policies in order to promote the effective development of forestry and the sustainable development of agriculture.

description: A brief overview is given of recent developments and fresh ideas at the intersection of PT and/or CPT-symmetric quantum mechanics with supersymmetric quantum mechanics (SUSY QM). We study the consequences of the assumption that the "charge" operator C is represented in a differential-operator form. Besides the freedom allowed by the Hermiticity constraint for the operator CP, encouraging results are obtained in the second-order case. The integrability of intertwining relations proves to match the closure of nonlinear SUSY algebra. In an illustration, our CPT-symmetric SUSY QM leads to non-Hermitian polynomial oscillators with real spectrum which turn out to be PT-asymmetric.

description: We propose a method to speed up the quantum adiabatic algorithm using catalysis by many-body delocalization. This is applied to random-field antiferromagnetic Ising spin models. The algorithm is catalyzed in such a way that the evolution approximates a Heisenberg model in the middle of its course, and the model is in a delocalized phase. We show numerically that we can speed up the standard algorithm for finding the ground state of the random-field Ising model using this idea. We also demonstrate that the speedup is due to gap amplification, even though the underlying model is not frustration-free. The crossover to speedup occurs at roughly the value of the interaction which is known to be the critical one for the delocalization transition. We also calculate the participation ratio and entanglement entropy as a function of time: their time dependencies indicate that the system is exploring more states and that they are more entangled than when there is no catalyst. Together, all these pieces of evidence demonstrate that the speedup is related to delocalization. Even though only relatively small systems can be investigated, the evidence suggests that the scaling of the method with system size is favorable. Our method is illustrated by experimental results from a small online IBM quantum computer, showing how to verify the method in future as such machines improve. The cost of the catalytic method compared to the standard algorithm is only a constant factor.

Material examined. 4 ♀♀, 1 ♂ (MNHN-IU-2018-1917) and 1 dissected ♀ (figured) from Phallusia mammillata (Cuvier, 1815), Banyuls-sur-Mer, France.
Remarks. The female of N. elongatus has short filiform processes on the dorsal wings of the pedigerous somites. There are 3 filiform processes on the dorsal wing of first pedigerous somite, two processes on each wing of the second and third pedigerous somites, and a single process on the wing of the fourth pedigerous somite (Giesbrecht, 1882; Illg & Dudley, 1965). However, other studies have indicated that these processes are sometimes absent (e.g. Buchholz, 1869), or present only on some of the wings (Fig. 92B, C).

description: The present paper describes a combined experimental and high performance computing study of new specific behaviors of the Strato-Rotational Instability (SRI). The confrontation of low frequency Particle Image Velocimetry (PIV) experimental data with Direct Numerical Simulations reveal new non-linear phenomena and patterns not yet observed in the SRI, that can contribute for our understanding of astrophysical flows, specially regarding phenomena related to accretion disk theories. The experiment designed to investigate these SRI related phenomena consists of a classical Taylor-Couette (TC) system with two concentric cylinders that can rotate independently under stable density stratification due to temperature gradients imposed in the axial direction. In the present investigations, Froude numbers are between 1.5

description: The North Carolina (NC) wine industry has grown rapidly over the past decade and is expected to grow even more as the worldwide wine consumption and export of wines rises. In the United States, the wine market has grown by 13.7 percent since 2002 in volume and by more than 15 percent in dollars as wine has progressed from being a beverage of an elite segment of the market to becoming a mainline beverage, taking its place alongside beer and liquor (MKF Research LLC, 2007; Oches, 2009). The Piedmont Triad Region is uniquely positioned to increase its presence in this industry. Of the 80 wineries in NC that are currently open to the public, nearly half are located in the Piedmont Triad Region. However, growing grapes and making wine is a long term commitment to a community, both financially and physically. The MKF Research report states that the capital-intensive nature of the winery and vineyard sectors is often underestimated, with new entrants to the industry at times unprepared for the extended cash requirements. In addition, only a few local institutions are familiar with the unique needs of the winemaking business. In order to address factors that will impede growth in this nascent industry, it is important to identify the state of the industry and obtain management perspectives on the needs and challenges facing their operations. This study provides information that would help gain a better understanding of the business issues and needs related to the wine and grape industry in North Carolina. Data for this study was drawn from a census of 34 wine producers located in the Yadkin, Swan Creek, and the Haw River valley regions of North Carolina. Descriptive statistics using frequencies and means is used to provide a demographic overview of the industry and to identify the factors that wine producers perceive to be important in affecting their profitability. Results from the study shows that most of the wineries share some common traits: they are small, relatively new to the wine and grape industry and grow grapes other than the traditional native Muscadine grape. Primarily, a majority of the wineries are family-based entrepreneurial businesses that have to behave like mini-conglomerates. These findings are consistent with a study conducted by Taplin and Breckenridge (2008).

description: Recent trend depicts that tomatoes and tomatoes products rank 2nd most important vegetable crop in the United States after potatoes and potatoes products contributing 20 percent of total vegetable production. More-so, tomato is equally ranked 2nd in the United States in terms of production value, generating $1.3 billion after head lettuce that contributed $1.4 billion in the same time period. In 2006, 422,000 acres of tomatoes were planted in the United States. Tomato is equally an important economic crop in the state of Georgia. In 2008, it ranked 14th in the Georgia vegetable acreage as 3,985 acres were planted. It also ranked 6th in terms of farm gate value in the same time period generating $51.2 million. Thrips-vectored tomato spotted wilt virus (TSWV) is a serious disease capable of causing damages to the plant, fruits, quality and reducing yields drastically. Managing TSWV can be complex. For instance, metalized UV-mulch may significantly reduce TSWV, but delay tomato maturity, potentially affecting price and market window. Also, resistant tomato lines may eliminate damages due to TSWV, but could have negative horticultural attributes that standard TSWV-susceptible hybrids do not. TSWV can induce irregular ripening in fruit after packing, affecting post harvest costs. This study is aimed at providing the optimal return per unit of enterprise using cost and benefit estimates of the combination of available inputs used in the various management strategies. Thereafter, the result of the differentially developed techniques and risk-rated cost and benefit budgets will be used to determine which of the risk-rated thrips, TSWV and IPM decision criteria would provide superior pareto-optimal economic and financial benefit to tomato growers
Trade Factors Affecting Apple Exports from China to Thailand

description: Export supply and import demand factors are used to examine the apple exports from China to Thailand. Error Correction Model (ECM) and Cochrane-Orcutt regression are applied to examine the apple trade from 1976 to 2007. China apples export supply to Thailand is only influenced by domestic production cost. An increase in China apples production cost leads to a decrease of export quantity to Thailand. The result is consistent with the Thailand import demand function, where import quantity is negatively related to the China apple export price. The real exchange rate also plays an important role in the apples trade between China and Thailand. Thai baht appreciation would cause Thai import less apples from China.

description: Sheep farming is an important agricultural activity in Greece, since it contributes highly in the country’s gross agricultural production value. Recently, sheep milk production received further attention because of the increased demand for feta cheese and also because of the excessive price level suffered by the consumers, in contrast with the prices paid at the farm level. In this study, we suggest the use of multicriteria analysis to estimate the supply response of sheep milk to price. The study focuses in the Prefecture of Etoloakarnania, located in Western Greece, where sheep farming is a common and traditional activity. A non-interactive technique is used to elicit farmers’ individual utility functions which are then optimized parametrically subject to technico-economic constraints, to estimate the supply function of sheep milk. Detailed data from selected farms, representing different farm types and management strategies, have been used in the analysis. The results indicate that the multicriteria model reflects the actual operation of the farms more accurately than the gross margin maximization model and therefore leads to a more robust estimation of the milk supply.

description: The primary objective of supply chain management is to fulfill customer demands through the most efficient use of resources, including distribution capacity, inventory and labor. A variety of optimizing aspects of the supply chain include acts as a go-between with suppliers to reduce bottlenecks. The sales and operation planning is becoming a requirement for doing well supply chain implementation. There are many key opportunities for improving the export and competitive performances of the sector of certified food products and eco-products. Romania has great openings for promoting and developing the ecological agriculture due to an agricultural area of 14.8 million hectares and unpolluted soils. One of the major points is to confine and maintain a greater part from the nationwide element of value chain during the orientation of production and sales towards primary products. It is also required a better promotion of Romanian food products on external markets, as well as a more intensive niche marketing and consolidation of the existing ones. Another concern is to create a suitable manufacturing, processing and marketing system for food products, aimed to suit the needs of national and foreign markets. The development of the research area of activities related to food products and markets has to be also increased.
