description: International trade theory suggests that advanced trade integration may lead to a higher level of intra-industry trade. The enlargement of the European Union (EU) during the last decade is a good example to analyse the intra-industry trade in wine products. The aim of the paper is to analyse the pattern and drivers of horizontal intra-industry trade in the wine sector within the EU between 2000 and 2011. We employ an empirical strategy developed by Cieślik (2005) to test Helpman and Krugman (1985) model. We find a growing trend in intra-industry trade with dominance of vertical intra-industry trade. Estimations suggest that Belgium, France, the Netherlands and Germany report the highest level of intra-industry trade within the EU. The level of intra-industry trade is highest among old member states. Empirical evidence indicates that the standard intra-industry theory finds some support in our data when we control for the sum of capital to labour ratios in the estimated equations instead of relative country-size variables. We find that the EU enlargement positively influences total and vertical intra-industry trade while it has negative impacts on horizontal intra-industry trade. Distance has negative effects on all types of intra-industry trade.

description: The synthesis of some highly substituted three-dimensional cyclopentanes with multiple chiral centers and with high regiochemical and stereochemical diversity has been accomplished starting from cyclopentadiene-derived aminocyclopentenecarboxylic acids. The small-molecular design consisted of stereo- and regiocontrolled functionalization of the starting cyclopentene β- and γ-amino acids through oxirane formation/oxirane opening and afforded regio- and diastereoisomers of orthogonally protected aminocyclopentanecarboxylates.
The Orion Protostellar Explosion and Runaway Stars Revisited: Stellar Masses, Disk Retention, and an Outflow from BN

description: The proper motions of the three stars ejected from Orion's OMC1 cloud core are combined with the requirement that their center of mass is gravitationally bound to OMC1 to show that radio source I (Src I) is likely to have a mass around 15 Solar masses consistent with recent measurements. Src I, the star with the smallest proper motion, is suspected to be either an AU-scale binary or a protostellar merger remnant produced by a dynamic interaction ~550 years ago. Near-infrared 2.2 um images spanning ~21 years confirm the ~55 km/s motion of `source x' (Src x) away from the site of stellar ejection and point of origin of the explosive OMC1 protostellar outflow. The radial velocities and masses of the Becklin-Neugebauer (BN) object and Src I constrain the radial velocity of Src x to be V_{LSR} = -28 +/-10 km/s . Several high proper-motion radio sources near BN, including Zapata 11 ([ZRK2004] 11) and a diffuse source near IRc 23, may trace a slow bipolar outflow from BN. The massive disk around Src I is likely the surviving portion of a disk that existed prior to the stellar ejection. Though highly perturbed, shocked, and re-oriented by the N-body interaction, enough time has elapsed to allow the disk to relax with its spin axis roughly orthogonal to the proper motion.

description: The objective of this paper is to apply the stochastic production frontier methodology to a survey database collected in northern Vietnam. Our study finds that the average technical efficiency of tea production is only about 41 %. Among extension policy measures available to farmers, only training on production inputs has an improving impact on technical efficiency. Other features of policy have no significant effect, contrary to the expectation. The adoption of the oldest variety “Trung-Du” is not a source of inefficiency while the effects of other new varieties are insignificant. The results indicate that there is a great potential for improving production efficiency in the region of the study.

description: We construct an algorithm that generates large, band-diagonal transition matrices for a totally asymmetric exclusion process (TASEP) with local hopping rate inhomogeneities. The matrices are diagonalized numerically to find steady-state currents of TASEPs with local variations in hopping rate. The results are then used to investigate clustering of slow codons along mRNA. Ribosome density profiles near neighboring clusters of slow codons interact, enhancing suppression of ribosome throughput when such bottlenecks are closely spaced. Increasing the slow codon cluster size, beyond $\approx 3-4$, does not significantly reduce ribosome current. Our results are verified by extensive Monte-Carlo simulations and provide a biologically-motivated explanation for the experimentally-observed clustering of low-usage codons.
Quantum walks on graphs and quantum scattering theory

Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We discuss a particular kind of quantum walk on a general graph. We affix two semi-infinite lines to a general finite graph, which we call tails. On the tails, the particle making the walk simply advances one unit at each time step, so that its behavior there is analogous to free propagation We are interested in how many steps it will take the particle, starting on one tail and propagating through the graph (where its propagation is not free), to emerge onto the other tail. The probability to make such a walk in n steps and the hitting time for such a walk can be expressed in terms of the transmission amplitude for the graph, which is one element of its S matrix. Demonstrating this necessitates a study of the analyticity properties of the transmission and reflection amplitudes of a graph. We show that the graph can have bound states that cannot be accessed by a particle entering the graph from one of its tails. Time-reversal invariance of a quantum walk is defined and used to show that the transmission amplitudes for the particle entering the graph from different directions are the same if the walk is time-reversal invariant.

description: User representation learning is vital to capture diverse user preferences, while it is also challenging as user intents are latent and scattered among complex and different modalities of user-generated data, thus, not directly measurable. Inspired by the concept of user schema in social psychology, we take a new perspective to perform user representation learning by constructing a shared latent space to capture the dependency among different modalities of user-generated data. Both users and topics are embedded to the same space to encode users' social connections and text content, to facilitate joint modeling of different modalities, via a probabilistic generative framework. We evaluated the proposed solution on large collections of Yelp reviews and StackOverflow discussion posts, with their associated network structures. The proposed model outperformed several state-of-the-art topic modeling based user models with better predictive power in unseen documents, and state-of-the-art network embedding based user models with improved link prediction quality in unseen nodes. The learnt user representations are also proved to be useful in content recommendation, e.g., expert finding in StackOverflow.
Improved gravitational waveforms from spinning black hole binaries

description: The standard post-Newtonian approximation to gravitational waveforms, called T-approximants, from non-spinning black hole binaries are known not to be sufficiently accurate close to the last stable orbit of the system. A new approximation, called P-approximants, is believed to improve the accuracy of the waveforms rendering them applicable up to the last stable orbit. In this study we apply P-approximants to the case of a test-particle in equatorial orbit around a Kerr black hole parameterized by a spin parameter q that takes values between -1 and 1. In order to assess the performance of the two approximants we measure their effectualness (i.e. larger overlaps with the exact signal), and faithfulness (i.e. smaller biases while measuring the parameters of the signal) with the exact (numerical) waveforms. We find that in the case of prograde orbits, that is orbits whose angular momentum is in the same sense as the spin angular momentum of the black hole, T-approximant templates obtain an effectualness of ~ 0.99 for spins q < 0.75. For 0.75 < q < 0.95, the effectualness drops to about 0.82. The P-approximants achieve effectualness of > 0.99 for all spins up to q = 0.95. The bias in the estimation of parameters is much lower in the case of P-approximants than T-approximants. We find that P-approximants are both effectual and faithful and should be more effective than T-approximants as a detection template family when q>0. For q<0 both T- and P-approximants perform equally well so that either of them could be used as a detection template family.

description: The electroweak CP violating rate asymmetries in the decay $b \to d l^+ l^-$ are reexamined in detail and updated. In particular, the rate asymmetries are studied when one of the final state leptons is polarised. We find an estimate for the asymmetry of (5-15)% in the polarised decay spectrum which is close to known results for the unpolarised case. Interestingly, in the region separating the $ρ-ω$ and $c \bar c$ resonances, which is also theoretically cleanest, the polarised contribution to the asymmetry is larger than the unpolarised result. A $3σ$ signal for direct CP violation, requires about 10^{10} $B \bar B$ pairs at a B factory. In general these results indicate an asymmetric contribution from the individual polarisation states to the unpolarised CP asymmetry; an atribute for any new physics searches.

description: The Cicadellidae (Auchenorrhyncha: Hemiptera) are important agricultural, horticultural and ornamental pests. But it is very difficult to define nymphs and female adults using morphological characteristics. This research was aimed at understanding the variety of leafhoppers species and defining the prospective cause of the aster-yellow disease in China Aster, Marigold and Chrysanthemum. Two surveys were conducted in and around Pune, Maharashtra and Bengaluru, Karnataka between November 2016 and February 2017. The mitochondrial cytochrome oxidase subunit I (mtCOI) region marker was used in the species diagnosis and genetic diversity research. Through the use of mtCOI molecular marker eight different leafhoppers species were identified as Sogatella furcifera, Homalodisca insolita, Amrasca biguttula, Balclutha incise and Balclutha abdominalis and Japanagallia trifurcate. Whereas at genus level identified as Toya, Empoasca, Perkinsiella, Hishimonus, Tambocerus, Phaconeura, Curena, Psammotettix and Graphocophala species. These results are strongly corroborated with morphological identification. On the basis of multiple sequence alignment of the mtCOI gene, a species phylogenetic tree with the highest likelihood was drawn. All the leafhopper species clustered together in accordance with the species data collected from the database of the different geographic regions from the NCBI GenBank and Barcode of Life (BOLD). Such results suggest that it is important to use both molecular and morphological methods to ensure accurate identification of organisms. To conclude, this research contributes valuable knowledge to molecular biology and recognizes leafhopper species that serve as major phytoplasma vectors.

description: In a physical renormalization scheme, gauge couplings are defined directly in terms of physical observables. Such effective charges are analytic functions of physical scales, and thus mass thresholds are treated with their correct analytic dependence. In particular, particles will contribute to physical predictions even at energies below their threshold. This is in contrast to unphysical renormalization schemes such as MS-bar, where mass thresholds are treated as step functions. In this paper we analyze supersymmetric grand unification in the context of physical renormalization schemes and find a number of qualitative differences and improvements in precision over conventional approaches. The effective charge formalism presented here provides a template for calculating all mass threshold effects for any given grand unified theory. These new threshold corrections may be important in making the measured values of the gauge couplings consistent with unification.

description: Smooth time dependent supergravity solutions corresponding to analytic continuations of Kerr black holes are constructed and limits with a local de Sitter phase are found. These solutions are non-singular due to a helical twist in space and a fine tuning of the energy flow in the spacetime. For the extremal limit in which the mass and twist parameters are equal the S-brane undergoes de Sitter expansion. Subextremal limits show the formation and decay of a twisted circle and closed string tachyon condensation backreaction effects can be followed. For small values of the twist deformation, a short lived ergosphere envelopes the S-brane and leads to the production of closed timelike curves.

description: A majority of States have implemented State-sponsored agricultural credit programs to help resident farmers obtain capital to begin or sustain agricultural production enterprises. The programs are designed to improve access to needed capital and to lower interest rate costs. Surveys conducted by the U.S. Department of Agriculture's Economic Research Service indicate that 32 States currently provide 81 credit programs with preferential credit terms for farmers and ranchers. This handbook details the programs offered on a State-by-State basis. For a credit program to be included, loan proceeds had to be used to purchase land, machinery, or other operating inputs used in the agricultural production enterprises. The number of States sponsoring credit programs is rising, with a trend toward programs that move expenses off budget and reduce the associated financial risk to the States. Information presented in this handbook should be useful to policymakers, program administrators, and public and private entities interested in designing future programs.

description: We reconsider the contribution due to $πa_1$-mixing to the anomalous $γ\toπ^+π^0π^-$ amplitude from the standpoint of the low-energy theorem $F^π=e f_π^2 F^{3π}$, which relates the electromagnetic form factor $F_{π^0\toγγ}=F^π$ with the form factor $F_{γ\toπ^+π^0π^-}=F^{3π}$ both taken at vanishing momenta of mesons. Our approach is based on a recently proposed covariant diagonalization of $πa_1$-mixing within a standard effective QCD-inspired meson Lagrangian obtained in the framework of the Nambu-Jona-Lasinio model. We show that the two surface terms appearing in the calculation of the anomalous triangle quark diagrams or AVV- and AAA-type amplitudes are uniquely fixed by this theorem. As a result, both form factors $F^π$ and $F^{3π}$ are not affected by the $πa_1$-mixing, but the concept of vector meson dominance (VMD) fails for $γ\toπ^+π^0π^-$.

Conservation status

Distribution
Its population in Belgium has declined around 50 % to 80 % between 1900-1969 and 1970-2017, with severely fragmented populations (Drossart 2019). Few populations remain in Pays de Herve, Condroz and Plateaux Limoneux Hennuyers (Drossart 2019). The drastic decline of leguminous crops and nutrient-poor grasslands is probably a major driver of this decline.
Notes
Eucera nigrescens primarily inhabits meadows and grasslands rich in Fabaceae, as these plants are its main foraging source (Standfuss 2009). Females exclusively collect pollen from Fabaceae species, while males are often associated with the orchid Ophrys fuciflora (Gaskett 2010). The single specimen we collected was observed foraging on a Lathyrus species.
Diagnosis
One of the two Eucera species in Belgium. Compared to E. longicornis, E. nigrescens (Fig. 10) it has a domed and elongated clypeus, and the mesonotum weakly punctuated (Amiet et al. 2007). In males, the mesosoma hair colour varies considerably, ranging from brown to silver, whereas, in females, the variation is more limited, primarily spanning from light to dark brown.

description: The theory of collisional depolarization of spectral lines by atomic hydrogen (Derouich et al. 2003a; Derouich et al. 2003b) is extended to $f$-atomic levels $(l$=3). Depolarization rates, polarization and population transfer rates are calculated and results are given. Each cross section as a function of the effective quantum number for a relative velocity of 10 $\textrm{km s}^{-1}$ is given together with an exponent $λ$, if it exists, on the assumption that the cross section varies with velocity as $v^{-λ}$. A general trends of depolarization rates, of polarization transfer rates and of population transfer rates are given. A discussion of our results is achieved.

description: This report provides an overview of the Russian domestic corn sector and the factors that affect corn import demand. Low domestic corn production and increasing demand for feed grains, the result of State policy to increase per capita consumption by expanding inventories, led to high levels of corn imports during the 1970's and 1980's. These imports were financed with hard currency export earnings and, later, through export assistance. Since the breakup of the USSR, most Russian corn imports continue to be centralized through the Government and distributed by the State company Roskhleboprodukt. Primary suppliers of corn to Russia (and the former Soviet Union) have included the United States, Argentina, China, Canada, Thailand, and Eastern Europe. However, since 1988, the United States has held 70-90 percent of the FSU corn import market share, largely due to available export supplies and, more recently, financial assistance. The most important determinants of import source are export financing and price. Quality characteristics could become more important when processors and livestock producers begin to make import decisions. Over the long run, Russian corn import demand could decline, given a smaller livestock sector and domestically produced feed substitutes.

description: This final design report presents the culmination of a collaborative effort between The team and UBC Campus and Community Planning (CCP), marking a significant milestone in the transformative redesign of the SW Marine Drive & 16th Avenue intersection. Central to this vision is the creation of an infrastructure that exemplifies safe, multi-modal transportation, embraces sustainable practices, and enhances the spatial quality of the UBC campus. The final design features a shifted intersection accommodating a stormwater detention pond at the low point of the project scope to reduce cliffside erosion risk and manage water sustainably on-site with little maintenance. Active transportation is promoted through extended trails, crossride crossings, and realigned bike lanes – all converging to encourage a shift towards more sustainable transit options. The roundabout varies from one to two lanes, depending on the leg to better accommodate specific traffic demands, slow drivers down by introducing some congestion, and decrease crossing distances for cyclists. There will be rectangular rapid flashing beacons (RRFB) on W 16th Ave. along with signage warning drivers to decrease speed to 30 kph, enhancing the safety of pedestrians and cyclists crossing. The desired speed from SIDRA analysis is 38.7 kph. Lastly, all lane widths will be decreased to 4 m and the northbound leg of SW Marine Dr. will be decreased to one lane to further reduce driver comfort and vehicular speeds. Aesthetically, the design integrates a visual "gateway" into the campus, complete with Musqueam art, providing users of a sense of arrival and indigenous presence on campus. The team’ engagement strategy has proven to be effective and has been instrumental in shaping a design that not only meets technical and functional requirements but also resonates with the cultural and social fabric of the campus community. The total estimated cost is $3,105,800, calculated based on material costs, hourly rates, and fixed fees. Construction will begin May 1, 2024, with completion estimated to be the September 27, 2024.

description: This report examines the impact of Federal commodity programs on returns to irrigation in the western United States. Returns to irrigation are defined as average returns to land, management, fixed capital, and water (above variable water cost), net of returns to dryland crop alternatives. Commodity market returns and program revenues per unit of applied irrigation water are estimated by field crop and subregion. Two representative study years - 1984 and 1987 - highlight the effect of differing commodity prices and program support levels under extreme market conditions. Aggregate returns to irrigation in western field-crop production were fairly constant over the two study years, averaging $33 per acre-foot of water. Program revenue contributions per unit-water were highest in the Southern and Northern Plains, and lowest in the Northern Mountain and Northern Pacific regions. Commodity programs had the greatest impact on returns to irrigation in rice and cotton production. Program contributions per unit-water were relatively low for the major food and feed grains in 1984; contributions increased significantly with expanded deficiency payments and program enrollment in 1987. Under less favorable market conditions, positive returns to irrigation were largely dependent on commodity program supports. Commodity policy reform increases opportunities for water conservation in western irrigated agriculture.
Credit as a Factor Influencing Farmland Values

description: The latest farmland boom-bust cycle of the 1970's and 1980's caused agricultural economists to search for an adequate explanation. Some viewed the excessive use of mortgage credit by the farm sector as a major contributor to the boom in farmland prices above what the farm sector's earnings picture would support. A look at the literature on factors determining farmland values, speculative farmland price bubbles, and the role of farm mortgage credit yields a remarkable lack of consensus. Some agricultural economists attributed the 1970's farmland price boom to excessive use of mortgage credit by farmers. However, there exists no general agreement among them as to one primary cause.

description: In 1990, a new intergovernmental mechanism was adopted in an attempt to improve the way rural development programs and policies are developed and administered. Now known as the National Rural Development Partnership, this initiative centers around the activities of Rural Development Councils established at the State and National level. Based on case studies of 16 State Councils and their Washington, DC-based counterpart, this report examines how the Councils have evolved and what they have accomplished, individually and in partnership with one another, during their formative years.
On the trace anomaly and the energy-momentum conservation of quantum fields at D=2 in classical curved backgrounds

description: We study the conformal symmetry and the energy-momentum conservation of scalar field interacting with a curved background at D=2. We avoid to incorporate the metric determinant into the measure of the scalar field to explain the conformal anomaly and the consequent energy-momentum conservation. Contrarily, we split the scalar field in two other fields, in such a way that just one of them can be quantized. We show that the same usual geometric quantities of the anomaly are obtained, which are accompanied by terms containing the new field of the theory.

On phase asymmetries in oscillatory pipe flow

description: We present results from direct numerical simulations (DNS) of oscillatory pipe flow at several dimensionless frequencies Wo = {6.5, 13, 26} and one fixed shear Reynolds number Re_τ = 1440. Starting from a fully-developed turbulent velocity field at that Re_τ, the oscillatory flow either relaminarises or reaches a conditionally turbulent or strongly asymmetric state depending on Wo. The numerical method is validated by demonstrating excellent agreement of our DNS results with experimental data and analytical predictions from literature for the limiting cases of non-oscillating but turbulent and oscillating but laminar pipe flow. For an oscillating turbulent pipe flow we further found a very good agreement between qualitative descriptions of the characteristic flow features observed in experiments and our DNS. Here, we focus on the observation of a strongly asymmetric behaviour between the positive and the negative half-cycles of the oscillatory pipe flow at Wo=6.5.

description: Agricultural subsidies in developed countries are usually viewed as economic benefits for the farmer, and thus, are considered to be "farmer-based." But agricultural subsidies can be viewed from another perspective--as economic costs to the citizens of the countries, and thus, could also be considered as "society-based." This report presents a method for measuring the cost to citizens of supporting agriculture in developed countries. The report analyzes the cost in total, per capita, and as a share of the national economy for 10 countries and the European Union from 1979 to 1991.
