description: Commercial interest in supply chain management in agribusiness firms has increased due to greater urbanization and globalization. While product differentiation, improved quality, more cost-effective transport, and timely delivery have contributed to the development of supply chains from farmgate to retail level, it is the consumer demand for variety, quality, and yearround availability that has provided the stimulus for the formation of these chains. Traditional agricultural and food businesses that focus only on price are unable to meet consumers’ expectations. Individually, chain members lack the means to respond to consumers’ demands. Understanding the concepts of supply chain management provides a means to manage the changes required in the system to efficiently respond to consumer needs, integrating and coordinating the efforts of all supply chain members. These changes include consolidating organizations at the farm, processor, and supermarket levels; organizing production to achieve economies of scale; and gaining market share and competitive strength to survive global competition. Th is paper highlights the importance of critical factors like mutual trust; leadership by one or two chain members; the use of information technology (IT) in input procurement, production planning, and market access; realignment of strategies to develop improved production methods to meet consumer preferences and food safety standards; and the intelligent use of market information to help small farmers to overcome production challenges and respond to the challenges of global markets.

description: An increase in the wage for domestic workers represents an increase in the prices of a close market substitute for home production. This paper analyzes the response of households in the hours of work at home of the female head or wife of the head to changes in the hourly price for domestic services. The results differ between women in the labor force and women not in the labor force, this second group showing an increase in home production associated with an increase in the price for domestic services. Surprisingly, though, the estimation of a home production model predicted a negative response for Ecuadorian women who are employed or looking for a job. That is, higher prices of domestic services were associated with a decrease in the hours of work at home for employed women. A possible explanation for this striking result is that the market for domestic workers has excess demand.

description: Higher dimensional space-time models provide us an alternative interpretation of nature, and give us different dynamical aspects than the traditional four-dimensional space-time models. Motivated by such recent interests, especially for future numerical research of higher-dimensional space-time, we study the dimensional dependence of constraint propagation behavior. The $N+1$ Arnowitt-Deser-Misner evolution equation has matter terms which depend on $N$, but the constraints and constraint propagation equations remain the same. This indicates that there would be problems with accuracy and stability when we directly apply the $N+1$ ADM formulation to numerical simulations as we have experienced in four-dimensional cases. However, we also conclude that previous efforts in re-formulating the Einstein equations can be applied if they are based on constraint propagation analysis.

description: Objective: To analyze the cross-sectional associations of family structure with mental health and attention deficit (hyperactivity) disorders (AD(H)D) in 11- to 17-year-old adolescents with early-onset type 1 diabetes participating in one of three baseline surveys as part of an ongoing cohort study. Methods: Parents (n=1,631) completed the Strengths and Difficulties Questionnaire to screen for their child's mental health and answered questions about their child's diagnosis of AD(H)D. Associations between mental health or AD(H)D and family structure were analyzed using multivariable logistic regression analyses adjusted for various personal and diabetes-related variables. Results: Compared to adolescents living with both parents, adolescents living with one parent and his/her partner had 2.35 (95% confidence interval 1.32; 4.21) higher odds of abnormal screening result and 2.08 (1.09; 3.95) higher odds of a borderline screening result while adolescents living with a single parent had 1.84 (1.07; 3.17)/1.08 (0.53; 2.21) higher odds of abnormal/borderline screening results. The odds ratios for diagnosed attention deficit (hyperactivity) disorder were 2.17 (0.98; 4.84) for adolescents living with one parent and his/her partner and 1.27 (0.54; 3.01) for those living with a single parent vs. both parents. Conclusions: Our results indicate higher odds of mental health problems and AD(H)D in adolescents with type 1 diabetes who do not live with both parents; this finding was most pronounced in individuals living with one parent and his/her partner vs. both parents. Longitudinal studies are needed to verify our results and elucidate the underlying mechanisms.

description: In low potential agricultural areas like the Honduran hillsides characterized by soil degradation and erosion, organic agriculture can provide a means to break the downward spiral of resource degradation and poverty. We use original survey data to analyze the factors influencing the decision to convert to organic agriculture. Previous studies have emphasized the role of spatial patterns in the diffusion and adoption of agricultural technologies in general and organic agriculture in particular. These spatial patterns can result from a variety of underlying factors. In this article we test various potential explanations, including the availability of information in the farmer's neighborhood, social conformity concerns and perceived positive external effects of the adoption decision, in a spatially explicit adoption model. We find that farmers who believe to act in accordance with their neighbors' expectations and with greater availability of information in their neighborhood network are more likely to adopt organic agriculture. Furthermore, perceived positive productivity spillovers to neighboring plots decrease the probability of adoption. We discuss the implications of our findings for the dissemination of sustainable agricultural technologies in low-potential agricultural areas in developing countries.
Unsupervised Program Synthesis for Images By Sampling Without Replacement

description: Program synthesis has emerged as a successful approach to the image parsing task. Most prior works rely on a two-step scheme involving supervised pretraining of a Seq2Seq model with synthetic programs followed by reinforcement learning (RL) for fine-tuning with real reference images. Fully unsupervised approaches promise to train the model directly on the target images without requiring curated pretraining datasets. However, they struggle with the inherent sparsity of meaningful programs in the search space. In this paper, we present the first unsupervised algorithm capable of parsing constructive solid geometry (CSG) images into context-free grammar (CFG) without pretraining via non-differentiable renderer. To tackle the \emph{non-Markovian} sparse reward problem, we combine three key ingredients -- (i) a grammar-encoded tree LSTM ensuring program validity (ii) entropy regularization and (iii) sampling without replacement from the CFG syntax tree. Empirically, our algorithm recovers meaningful programs in large search spaces (up to $3.8 \times 10^{28}$). Further, even though our approach is fully unsupervised, it generalizes better than supervised methods on the synthetic 2D CSG dataset. On the 2D computer aided design (CAD) dataset, our approach significantly outperforms the supervised pretrained model and is competitive to the refined model.

description: The concept of profitability has been widely debated in the international scientific economic community but there are few studies which contribute to connecting the profitability of micro and small agro-food holdings in PDO or PGI areas with their ability to stay afloat in a competitive market. This study compares the economic results of quality wine grape producers in Sicily providing an analysis of the impact and consequences of raised economic performance in local vine-grower economies. Economic indicators were employed to compare the profitability in two PDO areas, verifying if micro and small size farm quite remain competitive in an increasingly concentrated wine market. Detailed survey data was collected in 2 of the most important Sicilian PDO wine areas, showing the first results of some economic indicators which compare the vine-growing processes in each geographic area and evaluate the profitability of a sample of small grape producers. To evaluate the remuneration of capital and the ability of smallholder to compete in a global market, average farm profitability expressed as farm net value for each homogeneous area was calculated taking into account production costs and total output. Despite several studies demonstrating that PDO certification increases costs and profits our study reveals how DO does not always ensure adequate profitability for micro and small vine growers. The production and sale of unprocessed grapes does not provide any value-added products and local producers do not gain additional remuneration for the intangible components of their PDO grapes. Further analysis has required exploring to what extent these results are caused by increasing costs or by an inefficient market structure.

description: The prompt emission of gamma-ray bursts remains mysterious since the mechanism is difficult to understand even though there are much more observations with the development of detection technology. But most of the gamma-ray bursts spectra show the Band shape, which consists of the low energy spectral index $α$, the high energy spectral index $β$, the peak energy $E_{p}$ and the normalization of the spectrum. We present a systematic analysis of the spectral properties of 36 GRBs, which were detected by the Gamma-ray Burst Monitor (GBM), simultaneously, were also observed by the Large Area Telescope (LAT) and the LAT Low Energy (LLE) detector on the $Fermi$ satellite. We performed the detailed time-resolved spectral analysis for all of the bursts in our sample. We found that the time-resolved spectrum at peak flux can be well fitted by the empirical Band function for each burst in our sample. Moreover, the evolution patterns of $α$ and $E_{p}$ have been carried for statistical analysis, and the parameter correlations have been obtained such as $E_{p}-F$, $α-F$, and $E_{p}- α$, all of them are presented by performing the detailed time-resolved spectral analysis. We also demonstrated that the two strong positive correlations $α-F$ and $E_{p}-α$ for some bursts originate from a non-physical selection effects through simulation.

description: A method is described, which computes from an observed sample of events upper limits for production rates of particles, or, in case of appearance of a signal, the probability for an upwards fluctuation of the background. For any candidate, a weight is defined, and the computation is based on the sum of observed weights. Candidates may be distributed over many decay channels with different detection efficiencies, physical observables and different or poorly known background. Systematic errors with any possible correlations are taken into account and they are incorporated into the weight definition. It is investigated, under which conditions a Bayesian treatment of systematic errors is correct. Some numerical examples are given and compared with the results of other methods. Simple approximate formulas for observed and expected confidence levels are given for the limiting case of high count rates. A special procedure is introduced, which analyses input data in terms of polynomial distributions. It extracts confidence levels for a signal or background hypothesis on the basis of spectral shapes only, normalizing the total rate to the number of observed events.

description: 1. Diversifying sources of funding and financing is necessary to scale up freshwater ecosystem restoration and meet current EU policy targets.

2. While restoration teams recognise the need to diversify, they reveal a marked cautiousness in exploring private sources of funding and finance.

3. Barriers relate to specialised language and terminology, perceptions of reputational risk, and difficulty to articulate viable business plans for opportunities unlocked by ecosystem restoration.

4. Committed restoration teams put significant efforts in building new skills and capacity in socioeconomics, business, and finance to communicate and engage effectively with the private sector.

5. Support programmes, pilot initiatives, and guidance are needed to successfully accompany restoration teams in their diversification journey.

6. More effective enforcement of existing policies and regulations is needed to narrow the funding gap, while new ones must foster responsible private spending, lending and investment in restoration.

description: We study the predictions for BR(mu-> e+gamma) and BR(tau-> e,mu+gamma) in a class of recently proposed horizontal SU(2) model that leads to a 3 X 2 seesaw model for neutrino masses. We consider two such models and obtain the correct bi-large mixing pattern for neutrinos. In these models, the effective low energy theory below the SU(2)_H scale is the MSSM. Assuming a supersymmetry breaking pattern as in the minimal SUGRA models, we find that consistent with present g-2, b->s+gamma and WMAP dark matter constraints on the parameters of the model, the BR(mu-> e+gamma) prediction is accessible to the proposed MEG experiment at PSI making this class of models testable in the near future.

description: In this paper, we derive a new generalisation of the strong subadditivity of the entropy to the setting of general conditional expectations onto arbitrary finite-dimensional von Neumann algebras. The latter inequality, which we call approximate tensorization of the relative entropy, can be expressed as a lower bound for the sum of relative entropies between a given density and its respective projections onto two intersecting von Neumann algebras in terms of the relative entropy between the same density and its projection onto an algebra in the intersection, up to multiplicative and additive constants. In particular, our inequality reduces to the so-called quasi-factorization of the entropy for commuting algebras, which is a key step in modern proofs of the logarithmic Sobolev inequality for classical lattice spin systems. We also provide estimates on the constants in terms of conditions of clustering of correlations in the setting of quantum lattice spin systems. Along the way, we show the equivalence between conditional expectations arising from Petz recovery maps and those of general Davies semigroups.

description: Starting from the fact that the amount and distribution of precipitations and the intensity of drought, considering the condition and extant of the use of irrigation systems, result in relatively low and unstable level of crop yields, the starting hypothesis of the research is that the agro meteorological trends in the period 2007-2010 influenced the yield position of the analyzed agricultural sector of Serbia. The aim of the paper is to determine the level of impact of agro meteorological trends on yield position of the group of business entities in the prevailing market conditions. The subject of the research refers to the analysis of the operation of the Serbian agricultural sector under the following activity code 011-cultivation of crops, plants and gardening. As the main source of data, the paper uses the summary financial statements of a group of business entities from agricultural sector under the activity code 011 and agro meteorological data for the period 2007-2010. By using the qualitative and quantitative methods of financial statement analysis and the synthesis of research results, the conclusion has been made that agro meteorological conditions in the observed period of time and under the existing market conditions had a significant impact on the worsening of yield position of the Serbian agricultural sector under survey.

description: We provide a theoretical framework for the development of a solid-state thermal rectifier through a confinement in the available population of phonons on one side of an asymmetrically graded film stack. Using a modification of the phonon gas model to account for phonon filtering and population confinement, we demonstrate that for an ideal material, with low phonon anharmonicity, significant thermal rectification can be achieved even in the absence of ballistic phonon transport. This formalism is used to illustrate thermal rectification in a thin-film of diamond (1-5 nm) graded to dimensions > 1 μm exhibiting theoretical values of thermal rectification ratios between 0.75 and 6. Our theoretical formulation for thermal rectification is therefore expected to produce opportunities to design advanced solid-state devices that enable a variety of critical technologies.

description: The results of new spectroscopic analyses of 30 stars with giant planet and/or brown dwarf companions are presented. Values for Teff and [Fe/H] are used in conjunction with Hipparcos data and Padova isochrones to derive masses, ages, and theoretical surface gravities. These new data are combined with spectroscopic and photometric metallicity estimates of other stars harboring planets and published samples of F, G, and K dwarfs to compare several subsets of planet bearing stars with similarly well-constrained control groups. The distribution of [Fe/H] values continues the trend uncovered in previous studies in that stars hosting planetary companions have a higher mean value than otherwise similar nearby stars. We also investigate the relationship between stellar mass and the presence of giant planets and find statistically marginal but suggestive evidence of a decrease in the incidence of radial velocity companions orbiting relatively less massive stars. If confirmed with larger samples, this would represent a critical constraint to both planetary formation models as well as to estimates of the distribution of planetary systems in our galaxy.

Stochastic gauge fixing for N = 1 supersymmetric Yang-Mills theory

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The gauge fixing procedure for N=1 supersymmetric Yang-Mills theory (SYM) is proposed in the context of the stochastic quantization method (SQM). The stochastic gauge fixing, which was formulated by Zwanziger for Yang-Mills theory, is extended to SYM_4 in the superfield formalism by introducing a chiral and an anti-chiral superfield as the gauge fixing functions. It is shown that SQM with the stochastic gauge fixing reproduces the probability distribution of SYM_4, defined by the Faddeev-Popov prescription, in the equilibrium limit with an appropriate choice of the stochastic gauge fixing functions. We also show that the BRST symmetry of the corresponding stochastic action and the power counting argument in the superfield formalism ensure the renormalizability of SYM_4 in this context.

description: As deep learning techniques advance more than ever, hyper-parameter optimization is the new major workload in deep learning clusters. Although hyper-parameter optimization is crucial in training deep learning models for high model performance, effectively executing such a computation-heavy workload still remains a challenge. We observe that numerous trials issued from existing hyper-parameter optimization algorithms share common hyper-parameter sequence prefixes, which implies that there are redundant computations from training the same hyper-parameter sequence multiple times. We propose a stage-based execution strategy for efficient execution of hyper-parameter optimization algorithms. Our strategy removes redundancy in the training process by splitting the hyper-parameter sequences of trials into homogeneous stages, and generating a tree of stages by merging the common prefixes. Our preliminary experiment results show that applying stage-based execution to hyper-parameter optimization algorithms outperforms the original trial-based method, saving required GPU-hours and end-to-end training time by up to 6.60 times and 4.13 times, respectively.

description: We present the results of several numerical simulations of two dimensional axi-symmetric accretion flows around black holes using Smoothed Particle Hydrodynamics (SPH) in the presence of cooling effects. We consider both stellar black holes and super-massive black holes. We observe that due to {\it both radial and vertical oscillation} of shock waves in the accretion flow, the luminosity and average thermal energy content of the inner disk exhibit very interesting behaviour. When power density spectra are taken, quasi-periodic variabilities are seen at a few Hz and also occasionally at hundreds of Hz for stellar black holes. For super-massive black holes, the time scale of the oscillations ranges from hours to weeks. The power density spectra have a flat top behavior with average {\it rms} amplitude of a few percent and a broken power-law behavior. The break frequency is generally found to be close to the frequency where the shock oscillates.

description: Metallic K3C60 shows pronounced structure and a sharp Fermi edge in integrated photoemission spectra (PES) while the insulating K4C60 and K6C60 phases display only a broad structureless peak. We find that both types of spectra can be explained by the coupling to the optic vibrations of the K+/C60n- ionic lattice. This is suppressed in K3C60 due to metallic screening but is strong in the insulating phases. We use the non-crossing approximation to calculate the density of states (DOS) of electrons in K3C60 coupled to the intramolecular Hg modes in good agreement with the experiment. For K4C60 and K6C60 strong coupling to the low energy optic K+/C60n- modes controls the DOS and yields broad peaks in the PES. A moment expansion is used to calculate the position and width of these peaks which agree well with the experiment.

We show that with the existing data one can determine the amplitude, slope and curvature of the slope of the matter power spectrum with a few percent precision. Higher order statistics such as the bispectrum provide independent information that can confirm and improve upon the statistical precision from the power spectrum alone. The achievable precision is comparable to that from the cosmic microwave background with upcoming satellites, and complements it by measuring the power spectrum amplitude and shape at smaller scales. Since the data cover the redshift range 22.

description: Any structural transformation of water is sensitive to an external electric field, since water molecules have dipole moments. We study influence of external uniform electric field on crystallization of supercooled water enclosed between two graphene planes. Crystallization of such the system is caused by ordinary relaxation of the metastable phase into an ordered (crystalline) phase and by dipole alignment induced by an applied electric field. We found that this system at the temperature $T=268$ K, where water has the density $0.94$ g/cm$^3$ and the applied electric field is of the magnitude $E=0.5~\textrm{V}$/Angstrom, crystallizes into the cubic ice with few the defects, and the crystallization proceeds over the time scale $\sim 5.0$ ns. The obtained results can be directly used to develop the methods to drive by water crystallization.

description: With the growing competition for Federal dollars, the land grant universities were asked to justify their budget to the Congress and the Office of Management and Budget using benefitcost analysis. The authors review previous studies of returns to agricultural research and present an analysis of corn and soybean research that formed part of these universities' 1978 budget request for Federal monies. New research to increase corn and soybean production would bring very high returns, and consumers would be the primary beneficiaries. The large acreage affected by the research was an important reason for these high returns. Consumers would benefit from lower prices and the resulting increase in consumer surplus.

description: • Consideration of emotional response to climate education in a primary classroom • Exploration of emotions that teaching about climate change may raise for teacher, researcher and pupil • Identification of gender and cultural bias in children’s climate mitigation visions • Use of three stage approach to climate education with emotion navigated, not ignored Purpose: Climate change education and the emotional consequences this topic raises in the classroom has been largely ignored by researchers. This paper considers the emotional response to climate education in a primary classroom (age 9-10 years) in England and begins to explore the emotions that teaching about climate change may raise for both teacher, researcher and pupil. Design: Part of a long- term ethnographic project in a school in England. Analysis of c60, 9-10-year olds drawings, participant observation notes and research diaries. Limitations: This is a small study - further research with larger numbers, different ages and in different geographical regions are required with both pupils and teachers. Practical implications: This work identifies pedagogies that allow injustices children identify to be explored with emotional responses being navigated rather than ignored. Such approaches support wellbeing in the face of growing numbers of young people suffering from eco-anxiety.

description: We present microscopic and macroscopic magnetic properties of the highly frustrated antiferromagnet Ba$_{2}$Sn$_{2}$ZnCr$_{7p}$Ga$_{10-7p}$O$_{22}$, respectively probed with NMR and SQUID experiments. The $T$-variation of the intrinsic susceptibility of the Cr$^{3+}$ frustrated kagomé bilayer, $χ_{kag}$, displays a maximum around 45 K. The dilution of the magnetic lattice has been studied in detail for $0.29 \leq p \leq0.97$. Novel dilution independent defects, likely related with magnetic bond disorder, are evidenced and discussed. We compare our results to SrCr$_{9p}$Ga$_{12-9p}$O$_{19}$. Both bond defects and spin vacancies do not affect the average susceptibility of the kagomé bilayers.

description: The feasibility of quadratic programming as a means of integrating agricultural pricequantity relationships and regional resource availability is demonstrated for a California test case. Estimates are developed for producer's and consumer's surplus, values of vegetables and field crop production, and resource use considering alternative levels of commodity demand, functional price-quantity relationships, normalized prices, and OBERS production projections. The results of the study have implications for resource policy analysis, shortrun agricultural price forecast, resource situation and outlook work, commodity and resource projections, and an expanded role for regional river basin studies.

description: A generalized equation is constructed for a class of classical oscillators with strong anharmonicity which are not exactly solvable. Aboodh transform based homotopy perturbation method (ATHPM) is applied to get the approximate analytical solution for the generalized equation and hence some physically relevant anharmonic oscillators are studied as the special cases of this solution. ATHPM is very simple and hence provides the approximate analytical solution of the generalized equation without any mathematical rigor. The solution from this simple method not only shows excellent agreement with the exact numerical results but also found to be better accuracy in comparison to the solutions obtained from other established approximation methods whenever compared for physically relevant special cases.
Evidence for new physics from clusters ?

Subjects: subject: Astrophysics (astro-ph)

description: The abundance of local clusters is a traditional way to derive the amplitude of matter fluctuations. In the present work, by assuming that the observed baryon content of clusters is representative of the universe, we show that the mass temperature relation (M-T) can be specified for any cosmological model. This approach allows one to remove most of the uncertainty coming from M-T relation, and to provide an estimation of sigma\_8 whose uncertainty is essentially statistical. The values we obtain are fortuitously almost independent of the matter density of the Universe (sigma\_8 ~ 0.6-0.63) with an accuracy better than 5%. Quite remarkably, the amplitude of matter fluctuations can be also tightly constrained to similar accuracy from existing CMB measurements alone. However, the amplitude inferred in this way in a concordance model (Lambda-CDM) is significantly larger than the value derived from the above method based on X-ray clusters. Such a discrepancy would almost disappear if the actual optical thickness of the Universe was 0 but could also be alleviated from more exotic solutions: the existence of a new dark component in the Universe as massive neutrinos. However, recent other indications of sigma\_8 favor a high normalization. In this case, the assumption that the baryonic content observed in clusters actually reflects the primordial value has to be relaxed : either there exists a large baryonic dark component in the Universe or baryons in clusters have undergone a large depletion during the formation of these structures. We concluded that the baryon fraction in clusters is not representative and therefore that an essential piece of the physics of baryons in clusters is missing in standard structure formation scenario.
