Subjects: Agricultural and Food Policy

description: Agriculture represents an important political and economic issue in the stage of the EU enlargement. This is especially true for Poland, since it has the largest agricultural sector. The paper outlines the changes of agricultural policies and their impacts on the organisational structure. Further, it examines how the credit, land and tax policies, as well as exports, rural development and social measures and the existence of cooperatives affect the sector's performance. The article concludes that despite positive changes achieved in Polish agriculture, there are still problems, which can act as an obstacle for EU membership. Most of current problems stem from the lack of reforms to change the unviable small-scale farming structure that is responsible for depressed competition. Furthermore, due to the special treatment of private farmers, there is an overabundance of labour, especially of part-time farmers. This is the reason why results of the overall performance of the sector are low. Unless structural change is taking place, and well- tailored agricultural policies are in place, Polish agricultural sector will continue to suffer from its depressed competitiveness. Attempts at agricultural reform must be addressed from a broad socio-economic perspective and must include structural transformation with prospects of alternative employment.

description: We present a conjecture on the exact location of the multicritical point in the phase diagram of spin glass models in finite dimensions. By generalizing our previous work, we combine duality and gauge symmetry for replicated random systems to derive formulas which make it possible to understand all the relevant available numerical results in a unified way. The method applies to non-self-dual lattices as well as to self dual cases, in the former case of which we derive a relation for a pair of values of multicritical points for mutually dual lattices. The examples include the +-J and Gaussian Ising spin glasses on the square, hexagonal and triangular lattices, the Potts and Z_q models with chiral randomness on these lattices, and the three-dimensional +-J Ising spin glass and the random plaquette gauge model.

description: When it comes down to reality the political objective of securing reasonable income to farmers succeeds all other objectives in agricultural policy making. To be able to evaluate policy and design new policy it is of vital importance to know the overall income situation and how the agricultural sector work. This paper conclude that Danish farmers from 1973 to 2000 have had a reasonable relative income. The reason for this is not support but instead the possibility of dynamic structural adjustment on one hand and on the other hand a sound general economic policy which have made it possible for agriculture to be a integrated part of the overall economy. The traditional agricultural policy pursued by OECD countries based on direct and indirect price support have only in the very short run supported income. In fact the conclusion is clear traditional policy creates further mis-allocation of resources and thereby slowing the needed structural adjustment process that could help securing income.

description: This paper presents empirical evidence concerning the finite sample performance of conventional and generalized empirical likelihood-type estimators that utilize instruments in the context of linear structural models characterized by endogenous explanatory variables. There are suggestions in the literature that traditional and non-traditional asymptotically efficient estimators based on moment equations may, for the relatively small sample sizes usually encountered in econometric practice, have relatively large biases and/or variances and provide an inadequate basis for estimation and inference. Given this uncertainty we use a range of data sampling processes and Monte Carlo sampling procedures to accumulate finite sample empirical evidence concerning these questions for a family of generalized empirical likelihood-type estimators in comparison to conventional 2SLS and GMM estimators. Solutions to EL-type empirical moment-constrained optimization problems present formidable numerical challenges. We identify effective optimization algorithms for meeting these challenges.

description: Prior works in cross-lingual named entity recognition (NER) with no/little labeled data fall into two primary categories: model transfer based and data transfer based methods. In this paper we find that both method types can complement each other, in the sense that, the former can exploit context information via language-independent features but sees no task-specific information in the target language; while the latter generally generates pseudo target-language training data via translation but its exploitation of context information is weakened by inaccurate translations. Moreover, prior works rarely leverage unlabeled data in the target language, which can be effortlessly collected and potentially contains valuable information for improved results. To handle both problems, we propose a novel approach termed UniTrans to Unify both model and data Transfer for cross-lingual NER, and furthermore, to leverage the available information from unlabeled target-language data via enhanced knowledge distillation. We evaluate our proposed UniTrans over 4 target languages on benchmark datasets. Our experimental results show that it substantially outperforms the existing state-of-the-art methods.

description: Hard scattering in p-p collisions, discovered at the CERN ISR in 1972 by the method of leading particles, proved that the partons of Deeply Inelastic Scattering strongly interacted with each other. Further ISR measurements utilizing inclusive single or pairs of hadrons established that high pT particles are produced from states with two roughly back-to-back jets which are the result of scattering of constituents of the nucleons as desribed by Quantum Chromodynamics (QCD), which was developed during the course of these measurements. These techniques, which are the only practical method to study hard-scattering and jet phenomena in Au+Au central collisions at RHIC energies, are reviewed, as an introduction to present RHIC measurements.

description: This paper analyzes the effects of insecure property rights over land on the functioning of the land rental market in the Dominican Republic. It shows that insecurity of property rights not only reduces sharply the level of activity on the land rental market, but also causes market segmentation. A principal-agent framework is used to model the landlord's utility maximization, where he takes into account the risk of losing the land when it is not traded within a narrow local circle of confidence. Using data collected with a methodology that enables to characterize the entire market, we show that insecure property rights lead to matching in the tenancy market along socio-economic lines and hence severely limit access to land for the rural poor. Simulations suggest that improving tenure security would increase the total area rented to the poor by 63%. While a small fraction of this gain is achieved via formal titling, most is obtained through reducing conflicts over land and enhancing protection of property rights. Results also show the importance of minimum working capital endowments for the poor in gaining access to land in the rental market.

description: Using survey-data from Peru, this paper evaluates the impact of a pilot farmer-field-school (FFS) program on farmers' knowledge of integrated pest management (IPM) practices related to potato cultivation. We use both regression analysis controlling for participation and a propensity score matching approach to create a comparison group similar to the FFS participants in observable characteristics. Results are robust across the two approaches as well as with different matching methods. We find that farmers who participate in the program have significantly more knowledge about IPM practices than those in the non-participant comparison group. We also find that improved knowledge about IPM practices has a significant impact on productivity in potato production.

description: Machine learning (ML) has shown to advance the research field of quantum chemistry in almost any possible direction and has recently also entered the excited states to investigate the multifaceted photochemistry of molecules. In this paper, we pursue two goals: i) We show how ML can be used to model permanent dipole moments for excited states and transition dipole moments by adapting the charge model of [Chem. Sci., 2017, 8, 6924-6935], which was originally proposed for the permanent dipole moment vector of the electronic ground state. ii) We investigate the transferability of our excited-state ML models in chemical space, i.e., whether an ML model can predict properties of molecules that it has never been trained on and whether it can learn the different excited states of two molecules simultaneously. To this aim, we employ and extend our previously reported SchNarc approach for excited-state ML. We calculate UV absorption spectra from excited-state energies and transition dipole moments as well as electrostatic potentials from latent charges inferred by the ML model of the permanent dipole moment vectors. We train our ML models on CH$_2$NH$_2^+$ and C$_2$H$_4$, while predictions are carried out for these molecules and additionally for CHNH$_2$, CH$_2$NH, and C$_2$H$_5^+$. The results indicate that transferability is possible for the excited states.

description: Patterned magnetic nanostructures are potential candidates for future energy efficient, on-chip communication devices. Here, we have experimentally and numerically studied the role of nanochannels to manipulate spin waves in Ni80Fe20 connected nanodot arrays of varying filling fraction. Rich spin-wave spectra are observed in these samples, where the number of spin-wave modes decreases with increasing filling fraction due to the retrenchment of the demagnetizing field. The nanochannels affect the spin-wave modes of the connected dots through dipole-exchange coupling. For all modes the vertical nanochannels couple the nanodots, except for the highest frequency modes where all nanochannels act as coupler. This feature is further explored in the simulation, which reveals that only the highest frequency mode can propagate through all the nanochannels, analogues to an electronic demultiplexer. This study will be useful to understand the role of nanochannels in patterned magnetic nanostructures and their applications in spin-wave based communication devices.

description: We link farmland values to climatic, soil, and socioeconomic variables for counties east of the 100th meridian, the historic boundary of agriculture not primarily dependent on irrigation. Degree days, a non-linear transformation of the climatic variables suggested by agronomic experiments as more relevant to crop yield gives an improved fit and increased robustness. Estimated coefficients are consistent with the experimental results. The model is employed to estimate the potential impacts on farmland values for a range of recent warming scenarios. The predictions are very robust and more than 75% of the counties in our sample show a statistically significant effect, ranging from moderate gains to large losses, with losses in the aggregate that can become quite large under scenarios involving sustained heavy use of fossil fuels.
Deformation mechanisms of Inconel-718 at nanoscale by molecular dynamics

description: Ni-based superalloy Inconel-718 is ubiquitous in metal 3D printing where high cooling rate and thermal gradient are present. These manufacturing conditions are conducive to high initial dislocation density and porosity or void in the material. This work proposes a molecular dynamics (MD) analysis method that can examine the role of dislocations, cooling rates, void, and their interactions governing the material properties and failure mechanism in Inconel-718 using Embedded Atom Method (EAM) potential. Three different structures: nanowire (NW), nanopillar, and nanoplate are used throughout this work. Initially, strain rates are varied from 10^8s^-1 to 10^10s^-1 keeping the NW diameter and temperature constant at 3.17 nm and 300K respectively. Compressive loading is applied to a 7.04 nm nanopillar by applying a constant strain rate of 109 s^-1 while temperature is varied from 100K to 700K. Different cooling rates ranging from 0.5x10^10 K/s to 1 x 10^14 K/s are applied to nanoplates (with and without a central void). The size of the central void is kept fixed at 2.12 nm. Increasing strain rates in tension not only results in strain hardening but also increase in dislocation density. Our computational method is successful to capture extensive sliding on {111} shear plane, which leads to significant necking of the alloy before fracture due to dislocation. The high cooling rates creating non-equilibrium structure leads to high strength and ductile behavior. On the other hand, the low cooling rate forming well defined crystalline structure causes low strength and brittle behavior. This brittle to ductile transition is observed solely due to cooling rate. Cooling rate may diminish the void by healing the structure during solidifications process. Subsequent mechanical properties by varying temperature and size are also presented in detail.

The characteristic temperature $T^*$, below which the nuclear spin-lattice relaxation rate $1/T_1$ deviates from the relaxation rate of the bulk, shows a magnetic-field dependence. This dependence supports the theoretical prediction of the appearance of discrete energy levels.

description: In 1992, V. Weispfenning proved the existence of Comprehensive Groebner Bases (CGB) and gave an algorithm to compute one. That algorithm was not very efficient and not canonical. Using his suggestions, A. Montes obtained in 2002 a more efficient algorithm (DISPGB) for Discussing Parametric Groebner Bases. Inspired in its philosophy, V. Weispfenning defined, in 2002, how to obtain a Canonical Comprehensive Groebner Basis (CCGB) for parametric polynomial ideals, and provided a constructive method. In this paper we use Weispfenning's CCGB ideas to make substantial improvements on Montes DISPGB algorithm. It now includes rewriting of the discussion tree using the Discriminant Ideal and provides a compact and effective discussion. We also describe the new algorithms in the DPGB library containing the improved DISPGB as well as new routines to check whether a given basis is a CGB or not, and to obtain a CGB. Examples and tests are also provided.

description: Motivated by the problem relatedness between unsupervised domain adaptation (UDA) and semi-supervised learning (SSL), many state-of-the-art UDA methods adopt SSL principles (e.g., the cluster assumption) as their learning ingredients. However, they tend to overlook the very domain-shift nature of UDA. In this work, we take a step further to study the proper extensions of SSL techniques for UDA. Taking the algorithm of label propagation (LP) as an example, we analyze the challenges of adopting LP to UDA and theoretically analyze the conditions of affinity graph/matrix construction in order to achieve better propagation of true labels to unlabeled instances. Our analysis suggests a new algorithm of Label Propagation with Augmented Anchors (A$^2$LP), which could potentially improve LP via generation of unlabeled virtual instances (i.e., the augmented anchors) with high-confidence label predictions. To make the proposed A$^2$LP useful for UDA, we propose empirical schemes to generate such virtual instances. The proposed schemes also tackle the domain-shift challenge of UDA by alternating between pseudo labeling via A$^2$LP and domain-invariant feature learning. Experiments show that such a simple SSL extension improves over representative UDA methods of domain-invariant feature learning, and could empower two state-of-the-art methods on benchmark UDA datasets. Our results show the value of further investigation on SSL techniques for UDA problems.

description: We discuss the implications of recently discovered strange tribaryons in 4He(stopped-K-, p)S0 (3115) and 4He(stopped-K, n) S1 (3140) within the framework of deeply bound kbar states formed on shrunk nuclear cores. S1 (3140) corresponds to T=0 ppnK-, whereas S0 (3115) to T=1 pnnK-, which is an isobaric analog state of pppK-, predicted previously. The observed binding energies can be accounted for by including the relativistic effect and by invoking a medium-enhanced kbar-N interaction by 15%. We propose various experimental methods to further study these and related bound systems.

Tetra-hyperbolic and tri-hyperbolic optical phases in anisotropic metamaterials without magnetoelectric coupling due to hybridization of plasmonic and magnetic Bloch high-k polaritons

description: In this paper we reveal the physics behind the formation of tri- and tetra-hyperbolic phases in anisotropic metamaterials without magnetoelectric coupling and describe the anti-crossing splitting phenomenon in the hyperbolic dispersion which arises due to the hybridization of the plasmonic and magnetic Bloch high-k polaritons. This considerably deepens the understanding of the high-k polaritons and the topology of the optical iso-frequency surfaces in k-space and will find applications in optical nano-resolution imaging and emission rate and directivity control. To accomplish this, we develop a range of new techniques of theoretical optics for bianisotropic materials, including the quadratic index of refraction operator method, suitable to study the high-k polaritons with finite indices of refraction and the explicit expression for the characteristic matrix in generic bianisotropic media. We introduce the spatial stratification approach for the electric and magnetic responses of anisotropic homogeneous media to analyze the underlying Bloch waves. We believe that the formalisms developed here can be useful for the researchers in the field of theoretical optics of anisotropic and bianisotropic media in the future.

Particulate emissions by H.P.D.I. engines using thermophoretic sampling and electron microscopy
Creators: name: Nair, Anil Kumar
Publisher: name: University of British Columbia
Year: 2009

description: A particulate sampler was designed and built for sampling particulate material from engines, on to the Transmission Electron Microscope (TEM) grids. It was designed taking into account all the challenges from different points of view of fluid mechanics, heat transfer, emission statistics, aerosol mechanics and practicability. Several instruments like temperature controller, temperature indicator, heating wire, flowmeter, valves, thermocouples and suitable conduits and other accessories for the passage of hot exhaust gas from engines were connected to the sampler to set up a thermophoretic sampling system. The intended application of the sampling system was to help in getting a good idea about parameters of interest in aerosol behaviour like particle size range, particle number concentration on the grid, particle shapes, spherule dimensions and chemical composition for the exhaust particulate material from the High Pressure Direct Injection (HPDI) engines - the compression ignition engines using natural gas as the fuel. Sampling tests were conducted in HPDI engines at different load conditions, different speed conditions and different conditions of pilot pulse-width. The particles in the grids were examined carefully with the TEM and measurements were taken. The results have been compiled and reported in this thesis. The particle average number concentration as deposited on the grid increased with increasing load conditions and increasing quantities of pilot diesel fuel consumption. Particle size ranged from about 15 nm to about 20 microns in some cases. Due to the presence of enormous number of tiny particles and single independent spherules, their number concentration could not be accurately measured using visual assessments. However, the number concentrations of particles larger than 500 nm could be found out in all cases except at 85% load condition in an engine. The spherules were of different sizes and their sizes ranged from about 15 nm to 1.5 microns in some cases. Generally, the single independent spherules were smaller in size compared to those in the agglomerates of particles. Several notable features of the particles, were found during the analyses and they are reported in the results. Some assumptions were made in designing the sampler and in computing its deposition efficiency. Actual deposition was 10-20% of predicted values. The major sources of error are also mentioned. Descriptions of some notable micrographs are presented. The data collected during the analyses were thoroughly analyzed to reach conclusions regarding the performance of the sampler and particulate emission by HPDI engines. The research project has brought to light many aspects of particulate emission by HPDI engines and has helped in preparing a database on it.

description: Whether it be physical, biological or social processes, complex systems exhibit dynamics that are exceedingly difficult to understand or predict from underlying principles. Here we report a striking correspondence between the collective excitation dynamics of a laser driven ultracold gas of Rydberg atoms and the spreading of diseases, which in turn opens up a highly controllable experimental platform for studying non-equilibrium dynamics on complex networks. We find that the competition between facilitated excitation and spontaneous decay results in a fast growth of the number of excitations that follows a characteristic sub-exponential time dependence which is empirically observed as a key feature of real epidemics. Based on this we develop a quantitative microscopic susceptible-infected-susceptible (SIS) model which links the growth and final excitation density to the dynamics of an emergent heterogeneous network and rare active region effects associated to an extended Griffiths phase. This provides physical insights into the nature of non-equilibrium criticality in driven many-body systems and the mechanisms leading to non-universal power-laws in the dynamics of complex systems.

description: Do milk marketing orders affect various demographic groups differently? To answer this question, we use supermarket scanner data to estimate an incomplete demand system for dairy products. We use these estimates to simulate substitution among dairy products and the welfare impacts of price changes resulting from changes in milk marketing orders for various consumer groups. While we find little difference in own- and cross-price substitution elasticities of demand, the welfare effects of price changes vary substantially across demographic groups, with some losing and others winning from this government program.

description: We study the emission from an old supernova remnant (SNR) with an age of around 10^5 yrs and that from a giant molecular cloud (GMC) encountered by the SNR. When the SNR age is around 10^5 yrs, proton acceleration is efficient enough to emit TeV gamma-rays both at the shock of the SNR and that in the GMC. The maximum energy of primarily accelerated electrons is so small that TeV gamma-rays and X-rays are dominated by hadronic processes, pi^0-decay and synchrotron radiation from secondary electrons, respectively. However, if the SNR is older than several 10^5 yrs, there are few high-energy particles emitting TeV gamma-rays because of the energy loss effect and/or the wave damping effect occurring at low-velocity isothermal shocks. For old SNRs or SNR-GMC interacting systems capable of generating TeV gamma-ray emitting particles, we calculated the ratio of TeV gamma-ray (1-10 TeV) to X-ray (2-10 keV) energy flux and found that it can be more than ~10^2. Such a source showing large flux ratio may be a possible origin of recently discovered unidentified TeV sources.
