description: The collapse of massive stars not only produces observable outbursts across the entire electromagnetic spectrum but, for Galactic (or near-Galactic) supernovae, detectable signals for ground-based neutrino and gravitational wave detectors. Gravitational waves and neutrinos provide the only means to study the actual engine behind the optical outbursts: the collapsed stellar core. While the neutrinos are most sensitive to details of the equation of state, gravitational waves provide a means to study the mass asymmetries in this central core. We present gravitational wave signals from a series of 3-dimensional core-collapse simulations with asymmetries derived from initial perturbations caused by pre-collapse convection, core rotation, and low-mode convection in the explosion engine itself. A Galactic supernovae will allow us to differentiate these different sources of asymmetry. Combining this signal with other observations of the supernova, from neutrinos to gamma-rays to the compact remnant, dramatically increases the predictive power of the gravitational wave signal. We conclude with a discussion of the gravitational wave signal arising from collapsars, the leading engine for long-duration gamma-ray bursts.

description: The sustainable value framework (Hart and Milstein, 2003) allows conducting a diagnostics of a firm regarding its strategies for the creation of sustainable business value. We have applied this instrument to the field of agricultural business. The analysis of literature made it possible to identify activities that source value creation for agricultural enterprises. The activities were grouped into six topics, namely collaboration, diversification, product identity, distribution channels, knowledge and innovations, changes in production. Applying the sustainable value framework to locate these six topics allowed drawing the conclusions that agricultural enterprises are successful in pursuing business strategies in near-term perspective in both internal and external dimensions, while long-term oriented strategies such as innovativeness, knowledge acquisition and collaborations with external stakeholders are out of the radar of agricultural enterprises. These conclusions lead to the need to explore what agricultural enterprises require in order to create sustainable value in all segments of the framework. Acknowledgement :

description: For a closed oriented surface $ \Sigma $ we define its degenerations into singular surfaces that are locally homeomorphic to wedges of disks. Let $X_{\Sigma,n}$ be the set of isomorphism classes of orientation preserving $n$-fold branched coverings $ \Sigma\rightarrow S^2 $ of the two-dimensional sphere. We complete $X_{\Sigma,n}$ with the isomorphism classes of mappings that cover the sphere by the degenerations of $ \Sigma $. In case $ \Sigma=S^2$, the topology that we define on the obtained completion $\bar{X}_{\Sigma,n}$ coincides on $X_{S^2,n}$ with the topology induced by the space of coefficients of rational functions $ P/Q $, where $ P,Q $ are homogeneous polynomials of degree $ n $ on $ \mathbb{C}\mathrm{P}^1\cong S^2$. We prove that $\bar{X}_{\Sigma,n}$ coincides with the Diaz-Edidin-Natanzon-Turaev compactification of the Hurwitz space $H(\Sigma,n)\subset X_{\Sigma,n}$ consisting of isomorphism classes of branched coverings with all critical values being simple.

description: This experiment explored the influence of the presentation order of price and ingredients of food items on individuals' preference for minimally processed foods. We hypothesized that participants exposed to ingredients first would be more likely to purchase minimally processed foods compared to participants exposed to prices first. We recruited a total of 260 participants and after excluding incomplete survey respondents, our final sample size was 199 participants (143 females, 43 males, 9 nonbinary, and 4 preferred not to say). Our independent variable was the order in which participants saw the price or ingredients of food items. Participants completed our UBC Qualtrics online survey which included two groups: ingredients first (experimental group) and price first (control group). The items examined were: Soy Sauce, Peanut Butter, Brownies, Vegetable Soup, and Strawberry Jam. We conducted a Chi-Square Test of Independence and used the forced-choice question “Which of these two items are you most likely to buy?” to measure our dependent variable which was their preference for minimally processed foods. Unfortunately, there was no significant difference across conditions: our results did not support our hypothesis. We speculate on potential causes for our null findings and provide our clients with recommendations for future studies.

description: We show analytically and empirically that non-classical measurement errors in the two key variables in a hypothesized relationship can bias the estimated relationship between them in any direction. Furthermore, if the errors are correlated, correcting for either one alone can aggravate bias in the parameter estimate of interest relative to ignoring mismeasurement in both variables, a second best result with implications for a broad class of economic phenomena of policy interest. We illustrate these results empirically by demonstrating the implications of mismeasured agricultural output and plot size for the long-debated (inverse) relationship between size and productivity. Our data from Ethiopia show large discrepancies between farmer self-reported and directly measured values of crop output and plot size; these errors are strongly, positively correlated with one another. In these data, correlated non-classical measurement errors generate a strong but largely spurious estimated inverse size-productivity relationship. We demonstrate empirically our analytical result that correcting for just one measurement problem may aggravate the bias in the parameter estimate of interest.

description: Migration cum remittances has become an important livelihood strategy among households in most developing countries. This is because it provides migrant households with remittances that are uncorrelated with agricultural income. It is estimated that there are about 232 million migrants worldwide today. Remittances sent back home by these migrants is believed to have a huge impact on the socioeconomic conditions of families left behind in the country of origin. In Sub-Saharan Africa, Nigeria is the highest receiver of remittances. However, despite the huge remittances flow into the country, malnutrition, poverty and food insecurity are still widespread in Nigeria. This paper examined the impact of remittances on food security and nutrition of farming households in Kwara State of Nigeria. Descriptive analysis indicates that, compared to non-receiving households, remittances receiving households are better off in terms of total income, assets, calorie supply, micronutrients supply, as well as, child nutritional status. Econometric analyses show that remittance income contributes to improved calorie supply at the household level, an aspect which has not been analyzed previously. Likewise, household income net of remittances increase calorie supply in a significant way, but the effect is twice larger than the effect of remittance income. Acknowledgement :
A Firm-Level Reappraisal of Real Exchange Rate Undervaluation in China s Agricultural Exports and Growth

description: Matching firm- and country-level data with a panel dataset of China s agricultural exports at the firm-product-country-level, a measure of firm-level exposure to exchange rate undervaluation has been proposed based on estimates of the bilateral undervaluation of yuan versus other currencies. Empirical models find that a firm s agricultural exports significantly and positively increase with its exposure to undervaluation. The result remains robust to alternative sample selections, measurement choices, and model specifications. The elasticity, however, differs across firms for their productivity, financial constraint, ownership, trade mode, and subsidy status. With the mediation role of increased exports, the undervaluation exposure further accelerates the firm-level growth in both productivity and scale according to the path analysis. This mediation effect takes almost a half of the acceleration effect of undervaluation on labor productivity and employment growth. It takes even the entire effect as to the growth of total factor productivity, sales, value added, and capital stock. Acknowledgement :

description: Off-farm income constitutes a significant share of the household livelihood portfolios across Sub-Saharan Africa. Yet, the determinants of and dynamics in individuals participation in off-farm activities have not received adequate attention due to the broader weaknesses in individual-level data collection and the lack of longitudinal studies that track individuals over time. This paper uses national panel survey data from Ethiopia, Malawi, Nigeria, Tanzania and Uganda; provides recent empirical evidence on off-farm employment participation rates; and analyzes the drivers of entry into employment and continued employment. The analysis is conducted across gender, and across rural and urban areas. A significant share of the population participates in employment. Men participate in wage and self-employment to a greater extent compared to women across time as well as within and across countries, with the exception of women s rural non-farm entrepreneurship being more common in Ethiopia and Nigeria. The participation shares are static over time, with only marginal increases in Malawi and Tanzania. However, a substantial share enters and exits employment over time, pointing to the dynamic nature of employment. Drivers of entry into employment and continued employment are country-specific, with initial asset holdings, occurrence of shocks and social factors as most important determinants.

description: Many stylized facts about women in agriculture have been repeated for decades. Did nothing really change? Is some of this conventional wisdom simply maintained over time, or has it always been inaccurate? We use four rounds of cross-sectional data from Ghana to assess some of the facts and to evaluate whether gender patterns have changed over time. We focus on five main themes: land, cropping patterns, market participation, agricultural inputs, and employment. We add to the literature by showing new facts and evidence for more than 20 years. Results show that stylized facts do not always hold, and that some of these facts change over time. We find significant variation in the extent of (changes in) gender discrepancies across themes, different agroecological zones, ethnicities, household types and women s role in the household.

description: Romanian agricultural management is the most centralized in Eastern Europe. Production expanded favorably during the seventies, although rising costs and disappointing returns on investment held back net output. Some movement toward introducing market forces occurred in 1979 following the introduction of the New Economic Mechanism. This movement was overshadowed, however, by the strong centralist bias of the NEM. Economic crisis in the early eighties---caused by large debt service requirements and poor domestic performance--brought new attempts at management reform. Nonetheless, the result was more central control of agriculture, restrictive policies for the private sector, and a decline in domestic consumption. Little positive impact is expected, and continued disappointing performance economywide should keep farm imports depressed

description: Effects of changes in the farm-level price of sugar on the retail price of various products were examined. A polynomial distributed lag was used to determine if retail prices responded asymmetrically to changes in the farm-level price of sugar, and the length of time required for the price adjustment to occur. Results indicate that retail prices of the five products under consideration do not respond asymmetrically to changes in farm-level prices. Changes in raw sugar price were found to be statistically insignificant for three products. The relationship between changes in retail prices and raw sugar prices was found to be statistically significant for refined sugar and cola-type soft drinks.

description: The current research question of the study was “how the information that counselling services are free and an anti-stigma statement influence students’ intention to access UBC’s counselling services”. To operate the study, we hypothesized that providing clear information about the free price and using an anti-stigma statement would increase the intention of students to access UBC’s mental health counselling services compared to those not exposed to the information. We operated a between-subjects 2×2 factorial design, two independent variables are information of free price and anti -stigma statement. We obtained a final sample of 204, and used an online survey to measure the intention of participants to access UBC’s mental health counselling services. We used a two-way ANOVA analysis, the results showed no significant main effect of information of free price and anti -stigma statement; no significant interaction effect between information of free price and anti -stigma statement. Therefore, the result was inconsistent with our hypothesis. We suggested targeting stigmas more directly through the use of video intervention, self affirmation framing for targeted statements, and small incentives for completing screening surveys.

description: Income tax reform became a key issue in agriculture in tile 1970's and 198U 1 s. Empirical evidence based upon economic modeling of representative farms and statistical analysis of farmer responses to a tax policy survey, suggests that broad tax reform such as proposed by the U.S. Department of Treasury would lower farm taxes and would also receive substantial support among farmers. Tne interlinkages among tax policy and commodity program policies were found to be pervasive, and the implications of this for tax reform are developed. A broad, political economy approach to tax misallocation effects in agriculture and the benefits of tax reform is presented. Discussion of the symposium papers and presentation of an alternative economic approach to analyzing tax reform effects are presented in the final two papers.

description: This paper presents a systematic numerical study of the effects of noise on the invariant probability densities of dynamical systems with varying degrees of hyperbolicity. It is found that the rate of convergence of invariant densities in the small-noise limit is frequently governed by power laws. In addition, a simple heuristic is proposed and found to correctly predict the power law exponent in exponentially mixing systems. In systems which are not exponentially mixing, the heuristic provides only an upper bound on the power law exponent. As this numerical study requires the computation of invariant densities across more than 2 decades of noise amplitudes, it also provides an opportunity to discuss and compare standard numerical methods for computing invariant probability densities.

description: Two problems make estimation of import demand for developing countries extremely difficult. The first is a conceptual problem: how to model government intervention which simultaneously distorts consumer and producer prices and foreign exchange allocations. The second problem is a technical one: how to obtain econometrically consistent estimates of an import demand equation which includes all the major parameters, given only 10 years or less of time series data. Both of these problems are addressed in this paper which presents an attempt to estimate Mexican corn import demand. Results indicate that Mexican corn imports could be substantially reduced by transferring relatively small amounts of subsidies from consumers to producers. Furthermore, effects on Mexican corn import demands of world border prices, exchange rates, and foreign exchange allotments are insignificant.

description: Recent developments in unsupervised representation learning have successfully established the concept of transfer learning in NLP. Mainly three forces are driving the improvements in this area of research: More elaborated architectures are making better use of contextual information. Instead of simply plugging in static pre-trained representations, these are learned based on surrounding context in end-to-end trainable models with more intelligently designed language modelling objectives. Along with this, larger corpora are used as resources for pre-training large language models in a self-supervised fashion which are afterwards fine-tuned on supervised tasks. Advances in parallel computing as well as in cloud computing, made it possible to train these models with growing capacities in the same or even in shorter time than previously established models. These three developments agglomerate in new state-of-the-art (SOTA) results being revealed in a higher and higher frequency. It is not always obvious where these improvements originate from, as it is not possible to completely disentangle the contributions of the three driving forces. We set ourselves to providing a clear and concise overview on several large pre-trained language models, which achieved SOTA results in the last two years, with respect to their use of new architectures and resources. We want to clarify for the reader where the differences between the models are and we furthermore attempt to gain some insight into the single contributions of lexical/computational improvements as well as of architectural changes. We explicitly do not intend to quantify these contributions, but rather see our work as an overview in order to identify potential starting points for benchmark comparisons. Furthermore, we tentatively want to point at potential possibilities for improvement in the field of open-sourcing and reproducible research.

Single spin asymmetry $A_{UL}^{\sin(2ϕ_h-2ϕ_R)}$ in dihadron semi-inclusive DIS

description: The single longitudinal spin asymmetry $A_{UL}^{\sin(2ϕ_h-2ϕ_R)}$ of dihadron production in semi-inclusive deep inelastic scattering (SIDIS) is examined through helicity-dependent dihadron fragmentation function (DiFF) $G_1^\perp$. The correlation of the longitudinal polarization of a fragmenting quark with the transverse momenta of the produced hadron pair is illustrated by this DiFF. The experimental investigation for this azimuthal asymmetry in dihadron SIDIS by the COMPASS Collaboration has lately yielded a very small signal. Here, the unknown T-odd dihadron fragmentation function $G_1^\perp$ utilizing a spectator model is computed. The model has been successfully used to describe the dihadron production in both the unpolarized and the single polarized processes to access the asymmetry and clarify why the signal is very small. The transverse momentum dependent factorization method, in which the transverse momentum of the final state hadron pair is left unintegrated, has been considered. The $\sin(2ϕ_h-2ϕ_R)$ asymmetry at the COMPASS kinematics is estimated and we compare it with the data. Besides, the predictions on the same asymmetry are also made at the HERMES and Electron Ion Collider.

description: Tax officials rely upon sale price of real property to estimate the property's market value. Assessment-ratio studies, which compare the assessed value to market value of property, are a major use of sales data in the tax assessment system. In many States, however, limited verification of sales information collected for ratio studies may compromise the accuracy of data and results of studies conducted. The questionable quality of sales data found in the tax assessment system, plus concerns regarding the adequacy of sales prices of transferred properties to estimate market value of all other properties, most likely restrict uses of these data in research analyses that require a high level of statistical confidence.

description: We investigate the performance of a quantum Otto refrigerator operating in finite time and exploiting local counterdiabatic techniques. We evaluate its coefficient of performance and cooling power when the working medium consists a quantum harmonic oscillator with a time-dependent frequency. We find that the quantum refrigerator outperforms its conventional counterpart, except for very short cycle times, even when the driving cost of the local counterdiabatic driving is included. We moreover derive upper bounds on the performance of the thermal machine based on quantum speed limits and show that they are tighter than the second law of thermodynamics.

description: We develop the concept of quantum phase-space (Wigner) distributions for quarks and gluons in the proton. To appreciate their physical content, we analyze the contraints from special relativity on the interpretation of elastic form factors, and examine the physics of the Feynman parton distributions in the proton's rest frame. We relate the quark Wigner functions to the transverse-momentum dependent parton distributions and generalized parton distributions, emphasizing the physical role of the skewness parameter. We show that the Wigner functions allow to visualize quantum quarks and gluons using the language of the classical phase space. We present two examples of the quark Wigner distributions and point out some model-independent features.

description: Edge termination plays a vital role in determining the properties of 2D materials. By performing compelling ab initio simulations, a lowest-energy U-edge [ZZ(U)] reconstruction is revealed in the bilayer phosphorene. Such reconstruction reduces 60% edge energy compared with the pristine one and occurs almost without energy barrier, implying it should be the dominating edge in reality. The electronic band structure of phosphorene nanoribbon with such reconstruction resembles that of intrinsic 2D layer, exhibiting nearly edgeless band characteristics. Although ZZ(U) changes the topology of phosphorene nanoribbon (PNR), simulated TEM, STEM and STM images indicates it is very hard to be identified. One possible identify method is IR/Raman analyses because ZZ(U) edge alters vibrational modes dramatically. Beyond, it also increases the thermal conductivity of PNR 1.4 and 2.3 times than the pristine and Klein edges.

description: We used systematic arrays of camera traps combined with site-occupancy analyses to estimate the site-specific presence and probability of detection the principal target pests across the three main habitats of Waikato Region, classified by season. Cameras easily identified brushtail possums, hedgehogs, ship rats, wild house mice, and mustelids, i.e., stoats, feral ferrets and weasels taken as a group. The data comprise four sets of estimates, one set of 15 (five targets, three habitats) for each season of the year, total of 60. Of these, only 10 (17%) returned probabilities of detection of more than 50% for that species in that habitat at that season, given that at least one individual was present then. All pest species we monitored were present on pastoral land. Pasture makes up more than half of the land cover of the Waikato, so it supports large numbers even of species that are not abundant in that habitat. Hence, pest control operations intended to conserve indigenous species in protected forests need to allow for the important effects of rapid reinvasions of controlled areas from adjacent pasture.

description: We have investigated, in the framework of proximity effect theory, the interface transparency T of superconducting/normal metal layered systems which consist of Nb and high paramagnetic Pd deposited by dc magnetron sputtering. The obtained T value is relatively high, as expected by theoretical arguments. This leads to a large value of the ratio $d_{s}^{cr}/ ξ_{s}$ although Pd does not exhibit any magnetic ordering.

Doppler-resilient ground-Rydberg transition and its application in high-fidelity entangling gates with neutral atoms

description: The motion-induced dephasing is a severe problem that limits the accuracy of a quantum control process by using external laser fields in neutral Rydberg atoms. This dephasing is a major issue that limits the realizable fidelity of a quantum entangling gate with neutral atoms when there is a {\it gap} time for the Rydberg atom to drift freely. We find that such a dephasing can be largely suppressed by using a transition in a `V'-type dual-rail configuration. The left~(right) arm of this `V' represents a transition to a Rydberg state $|r_{1(2)}\rangle$ with a Rabi frequency $Ωe^{ikz}~(Ωe^{-ikz})$, where $z$ is frozen without atomic drift, but changes linearly in each experimental cycle. Such a configuration is equivalent to a transition between the ground state and a hybrid and time-dependent Rydberg state with a Rabi frequency $\sqrt2Ω$, such that there is no phase error whenever the state returns to the ground state. We study two applications of this method. First, it is possible to faithfully transfer the atomic state between a hyperfine ground state $|1\rangle$ and Rydberg states $|r_{1(2)}\rangle$ with no {\it gap} time between the excitation and deexcitation. Second, by adding infrared laser fields to induce transition between $|r_{1(2)}\rangle$ and a nearby Rydberg state $|r_3\rangle$ via a largely detuned low-lying intermediate state in the {\it gap} time, the atom can keep its internal state in the Rydberg level as well as adjust the population branching in $|r_{1(2)}\rangle$ during the {\it gap} time. This allows an almost perfect Rydberg deexcitation after the {\it gap} time, making it possible to recover a high fidelity in the Rydberg blockade gate. The theory paves the way for high-fidelity quantum control over neutral Rydberg atoms without cooling qubits to the motional ground states in optical traps.

description: The European Community's (EC's) self-sufficiency in milk rapidly increased during the last decade as production rose faster than consumption. As a result, dairy surpluses have burgeoned, and became a major problem for the EC. Although the EC relies heavily on export markets to dispose of its dairy surpluses, large stocks of dairy products accumulated. Supporting this important and productive sector is costly to the EC. In 1984, the EC introduced milk quotas to more effectively control dairy surpluses and program costs. This report examines the EC's production, consumption, and trade of milk and dairy products, and changes in dairy policies. It also surveys the impact of the EC's new dairy-quota policy on U.S. agricultural exports.
Nuclear absorption and anomalous $J/ψ$ suppression in Pb+Pb collisions

description: We discuss $J/ψ$ suppression in a QCD based nuclear absorption model. Centrality dependence of $J/ψ$ suppression in S+U and in Pb+Pb collisions are explained in the model. However, the model fails to explain the centrality dependence of $ψ\prime$ suppression. $ψ\prime$ suppression in S+U or in Pb+Pb collisions require additional suppression. Additional suppression of $ψ\prime$, due to hadronic comovers or due to QGP formation could not be distinguished in Pb+Pb collisions. We then show that the centrality dependence of the ratio, $ψ\prime$ over $J/ψ$, could possibly distinguish two scenario (e.g. QGP or hadronic comover) at RHIC energy.
