description: The paper discusses recent national trends in pesticide use in major crop production, identifying major national shifts in pesticide use between 1960 and 2007 by commodity and specific trends in herbicide and insecticide use in corn, cotton, and soybeans. The paper also shows how hedonic methods are used to calculate quality-adjusted price changes and implicit prices of the quality characteristics of pesticides for 1960 through 2007. In addition, the paper examines quality-adjusted price and quality trends in key corn and cotton states, and examines the major forces driving the pesticide trends.

description: It has become more and more difficult to recruit prospective American Ph.D. students in Agricultural and Applied Economics. The purpose of this study was to determine the extent of the problem, to ascertain why with respect to location and other important factors, and hopefully deduce recruiting solutions. Results indicate that the paramount factors in a profile of those willing to pay the price in terms of sacrifice and effort to obtain a Ph.D. encompass willingness to accept a relatively low starting salary with a Ph.D., likely to be a Foreign National, prone to be in a Midwestern university, and willing to relocate globally. Generally, the Ph.D. starting salary would have to increase dramatically to change the minds of graduate students not intending to pursue a Ph.D. including most American graduate students. A change in public policy appears to be the only real solution.
Higher Martian atmospheric temperatures at all altitudes increase the D/H fractionation factor and water loss

description: Much of the water that once flowed on the surface of Mars was lost to space long ago, and the total amount lost remains unknown. Clues to the amount lost can be found by studying hydrogen (H) and its isotope deuterium (D), which are produced when atmospheric water molecules H$_2$O and HDO dissociate. The difference in escape efficiencies of H and D (which leads to} an enhanced D/H ratio) is referred to as the fractionation factor $f$. Both the D/H ratio and $f$ are necessary to estimate water loss; thus, if we can constrain the range of $f$ and understand what controls it, we will be able to estimate water loss more accurately. In this study, we use a 1D photochemical model of the neutral Martian atmosphere to determine how $f$ depends on assumed temperature and water vapor profiles. We find that the exobase temperature most strongly controls the value of $f$ for thermal escape processes. When we include estimates of non-thermal escape from other studies, we find that the tropopause temperature is also important. Overall, for the standard Martian atmosphere, $f=0.002$ for thermal escape, and $f=0.06$ for thermal + non-thermal escape. We estimate that Mars has lost at minimum 66-122 m GEL of water. Importantly, our results demonstrate that the value of $f$ depends critically on non-thermal escape of D, and that modeling studies that include D/H fractionation must model both neutral and ion processes throughout the atmosphere.

Sustainable vegetable greenhouse production through bio-conversion of greenhouse solid wastes and re-utilization

Publisher: name: University of British Columbia
Year: 2009

description: Current practices of handling greenhouse wastes are not the sustainable ways to conserve agricultural lands and ground waters. This study developed a sustainable growing practice in the vegetable greenhouse industry. Waste handling (shredding) and the biodegradable plastics were investigated first. Then, different composting control algorithms and substrate recipes were tested in both lab scale and pilot scale composting. With a good control algorithm, composting of greenhouse wastes could reach the requirement for Process to Reduce Further Pathogens, PFRP (55 OC for 3 days). Ammonia emission might be a problem but it could be reduced by using air-recirculation or removed by a biofilter with compost as medium. Recirculation cooling control was found to be a more effective method, to maintain the process temperature below the set point, than any kind of temperature feedback control. Less leachate and condensate were found from the reactors with air recirculation control. Systems with air recirculation for cooling and aeration showed higher degradation rates, and also more consistent moisture content of the final compost. Alder bark was found out to be a better choice of bulking agent than hemlock bark in terms of better substrate structure, more carbon loss, less nitrogen loss, and higher process temperature. Shredding was proven to be not necessary before composting of prunings and it also helped minimizing the amount of leachate. Bulking agents (alder bark) of about 20-30% (in weight) were found necessary for composting prunings. For year-end wastes, a ratio of 62% vines, 13% used sawdust and 25% alder bark was recommended for in-vessel composting. Using conventional management techniques in greenhouse tomatoes, a similar yield using a 2:1 sawdust to amendment mix by could be achieved compared to conventional sawdust medium. Significant reduction of crown and root rot disease caused by Fusarium oxysporum f. sp. radicis- lycopersici in susceptible tomatoes was achieved by addition of the greenhouse compost amendment to seedling plugs or blocks, and by mixing with the sawdust medium. A mixture of 2:1 sawdust to amendment by volume was shown to be effective. The reduction in disease resulted in 74% improved yield over a full growing season under high disease pressure.

description: Quantum transport can be simulated with ultracold atoms by employing spin superpositions of fermions interacting with spin-dependent potentials. Here we first extend this scheme to an arbitrary number of spin components so as to allow simulating transport through a multiterminal quantum dot and derive a current formula in terms of a spin rotation matrix and potential phase shifts. We then show that a Fano resonance manifests itself in measuring a linear conductance at zero temperature in the case of two spin components. We also study how a weak interparticle interaction in bulk affects quantum transport in one dimension with the bosonization and renormalization techniques. In particular, we find that the conductance vanishes for an attractive interaction due to a bulk spin gap, while it is enhanced for a repulsive interaction by a power law with lowering the temperature or the chemical potential difference.

In sharp contrast to the Coulomb blockade typical of quantum dots, E$_g$ is {\it reduced} by the Coulomb effects. The conductance of a thin C$_{60}$ layer sandwiched between metal (Al, Ag, Au, Mg and Pt) contacts is investigated. Excellent Ohmic conductance is observed for Al electrodes protected with ultra-thin LiF layers. First-principles calculations, Hubbard models etc., show that the energy gap of C$_{60}$ is dramatically reduced when electrons hop from C$_{60}^-$ to C$_{60}$.

description: A model is developed to quantify the special status of agriculture in the US and the EC trade negotiations. The role of special interests are measured by a policy goals function (PGF) whose weights are estimated for each special interest group. The analysis searches for mutually acceptable, mutually advantageous trade agreements between the US and the EC using a partial equilibrium world trade model coupled with game theory. Results suggest that it is in the best interest of the US (resp. EC) 'for the EC (resp. US) to liberalize whi1e the other follows the status quo policies of 1986. Mutual gains in PGF values to both countries pursuing "large" liberalizations are unlikely to exist, although "small" liberalizations may give rise to "small" mutual gains. Altering each country's action space, and permitting compensatory payments to the most influencial groups yields trade liberalization, but free trade does not result.

description: A mathematical programming model of a representative New York dairy farm is developed to identify optimal management adjustments to increased availability of corn distillers dried grains with solubles (DDGS). While at current prices DDGS feeding is limited to dry cows and young stock, as prices decrease, DDGS in lactating cow rations increase from 7.4% to 20% on a dry matter basis. While expected changes in net farm returns are modest, more important is the consideration of changes in nutrient management practices necessary to deal with increasing levels of nitrogen and phosphorus in the animal waste.

description: We report results of multiband optical monitoring of two well known blazars, S5 0716+714 and BL Lacertae, carried out in 1996 and 2000-01 with an aim to study optical variations on time scales from minutes to hours and longer.The light curves were derived relative to comparison stars present on the CCD frames. Night to night flux variations of >0.1 mag were observed in S5 0716+714 during a campaign of ~2 weeks in 1996.A good correlation between the lightcurves in different optical bands was found for both inter-night and intra-night observations. Two prominent events of intra-night optical variability were detected in S5 0716+714.Each of these rapidly varying segments of the lightcurves trace an exponential flux profile whose rate of variation is the same in both cases. Our long-term monitoring data of S5 0716+714 showed a distinct flare around JD 2451875 which can be identified in the BVRI bands.This flare coincides with the brightest phase recorded during 1994-2001 in the long-term lightcurves reported by Raiteri et al.(2003). No evidence for the bluer when brighter trend was noticed on inter-night and intra-night time scales. On the other hand, our nearly simultaneous multiband observations of BL Lacertae in October 2001 showed flux variations that were not achromatic. This blazar was found to become bluer when brighter on intra-night time scales and there is a hint of the same trend on inter-night time scales. Based on five nights of observations during a week, BL Lacertae showed a peak night-to-night variability of ~0.6 mag in B. Thus, we found that the present observations of the two blazars, reveal a contrasting behaviour in terms of the dependence of spectral hardening with increasing brightness, at least on intra-night, and possibly also on inter-night, time scales.

description: The data-driven computing paradigm initially introduced by Kirchdoerfer & Ortiz (2016) is extended by incorporating locally linear tangent spaces into the data set. These tangent spaces are constructed by means of the tensor voting method introduced by Mordohai & Medioni (2010) which improves the learning of the underlying structure of a data set. Tensor voting is an instance-based machine learning technique which accumulates votes from the nearest neighbors to build up second-order tensors encoding tangents and normals to the underlying data structure. The here proposed second-order data-driven paradigm is a plug-in method for distance-minimizing as well as entropy-maximizing data-driven schemes. Like its predecessor, the resulting method aims to minimize a suitably defined free energy over phase space subject to compatibility and equilibrium constraints. The method's implementation is straightforward and numerically efficient since the data structure analysis is performed in an offline step. Selected numerical examples are presented that establish the higher-order convergence properties of the data-driven solvers enhanced by tensor voting for ideal and noisy data sets.

description: Uncorrelated random scale-free networks are useful null models to check the accuracy an the analytical solutions of dynamical processes defined on complex networks. We propose and analyze a model capable to generate random uncorrelated scale-free networks with no multiple and self-connections. The model is based on the classical configuration model, with an additional restriction on the maximum possible degree of the vertices. We check numerically that the proposed model indeed generates scale-free networks with no two and three vertex correlations, as measured by the average degree of the nearest neighbors and the clustering coefficient of the vertices of degree $k$, respectively.

description: The generalized minimal subtraction scheme for ultraviolet renormalization (Kuznetsov and Tkachov, 1988) is fine-tuned with applications in mind. The resulting $\text{MS}^4$ scheme obviates extraneous regularizations and renders momentum integrands integrable by subtracting troublesome asymptotic terms in a physically correct fashion due to the use of special minimal subtraction operators defined congruously with the physically natural Polchinski cutoffs. A direct derivation of the Callan-Symanzik equations avoids divergent renormalization factors or counterterms, and automatically yields explicit exact finite integral expressions for renormalization group functions.

description: China’s spectacular growth and poverty reduction has been accompanied by growing inequality which threatens the social compact and thus the political basis for economic growth and social development. The regional dimension of inequality— rural/urban, inland/coastal and provincial—dominates in a country as large as China, and especially with its particular history. The three of us have been researching Chinese regional inequality for over a decade. In a series of papers which have been published in peer reviewed journals, we have been involved in a systematic investigation into the nature and evolution of regional inequality in China. The object of this volume is to bring together a selection of these papers by us and our co-authors, so that researchers and policy makers can have access to them in one place. This introduction provides an overview of the volume.

description: We report on the synthesis, STM imaging and theoretical studies of the structure, electronic structure and transport properties of linear chains of styrene and methyl-styrene molecules and their heterojunctions on hydrogen-terminated dimerized silicon (001) surfaces. The theory presented here accounts for the essential features of the experimental STM data including the nature of the corrugation observed along the molecular chains and the pronounced changes in the contrast between the styrene and methyl-styrene parts of the molecular chains that are observed as the applied bias is varied. The observed evolution with applied bias of the STM profiles near the ends of the molecular chains is also explained. Calculations are also presented of electron transport along styrene linear chains adsorbed on the silicon surface at energies in the vicinity of the molecular HOMO and LUMO levels. For short styrene chains this lateral transport is found to be due primarily to direct electron transmission from molecule to molecule rather than through the silicon substrate, especially in the molecular LUMO band. Differences between the calculated position-dependences of the STM current around a junction of styrene and methyl-styrene molecular chains under positive and negative tip bias are related to the nature of lateral electron transmission along the molecular chains and to the formation in the LUMO band of an electronic state localized around the heterojunction.

Vertex cover in the sliding window model
Creators: name: Nalam Venkata Subrahmanya, Sai Krishna Chaitanya
Publisher: name: No Publisher Supplied
Year: 2021

description: We study the problem of finding the minimum vertex cover for a graph in the sliding window model. The sliding window model is similar to the original streaming model where the edges of a graph whose vertices are known, arrive sequentially in a stream. However, in the sliding window model, only the graph induced by recent w edges of the stream is considered in computing the output. Therefore, when a new edge is arrived, the oldest edge would be deleted from the graph and not considered anymore in the computation of the output. Since we are only allowed to use o(w) space, all the recent w edges of the stream cannot be stored and we cannot explicitly find the edge that is getting deleted. This implicit deletion makes the sliding window model harder when compared to the original streaming model.In this work, we observe that the (3 + ε)-approximation algorithm (ε ∈ (0, 1)) for maximum matching in the sliding window model can give a (6+O(ε))-approximation for the minimum vertex cover problem in the sliding window model. We give a counter example to the existing analysis of a (4 + ε)-approximation algorithm for the minimum vertex cover problem in the sliding window model and provide a correct analysis for the same algorithm. Finally, we come up with a (3 + ε)-approximation algorithm for the minimum vertex cover problem in the sliding window model using ̃O(n) space, where ∼ encompasses 1/ε,logn factors with n being the number of vertices in the graph.

description: Using analytical theory and hybrid-kinetic numerical simulations, we demonstrate that, in a collisionless plasma, long-wavelength ion-acoustic waves (IAWs) with amplitudes $δn/n_0 \gtrsim 2/β$ (where $β\gg{1}$ is the ratio of thermal to magnetic pressure) generate sufficient pressure anisotropy to destabilize the plasma to firehose and mirror instabilities. These kinetic instabilities grow rapidly to reduce the pressure anisotropy by pitch-angle scattering and trapping particles, respectively, thereby impeding the maintenance of Landau resonances that enable such waves' otherwise potent collisionless damping. The result is wave dynamics that evince a weakly collisional plasma: the ion distribution function is near-Maxwellian, the field-parallel flow of heat resembles its Braginskii form (except in regions where large-amplitude magnetic mirrors strongly suppress particle transport), and the relations between various thermodynamic quantities are more `fluid-like' than kinetic. A nonlinear fluctuation-dissipation relation for self-sustaining IAWs is obtained by solving a plasma-kinetic Langevin problem, which demonstrates suppressed damping, enhanced fluctuation levels, and weakly collisional thermodynamics when IAWs with $δn/n_0 \gtrsim 2/β$ are stochastically driven. We investigate how our results depend upon the scale separation between the wavelength of the IAW and the Larmor radius of the ions, and discuss briefly their implications for our understanding of turbulence and transport in the solar wind and the intracluster medium of galaxy clusters.

description: We study the impact of analyst forecasts on prices to determine whether investors learn about analyst accuracy. Our test market is the crude oil futures market. Prices rise when analysts forecast a decrease (increase) in crude supplies. In the 15 minutes following supply realizations, prices rise (fall) when forecasts have been too high (low). In both the initial price action relative to forecasts and in the subsequent reaction relative to realized forecast errors, the price response is stronger for more accurate analysts. These price reactions imply that investors learn about analyst accuracy and trade accordingly.

description: How does labor market competitiveness frame the impact of greater labor productivity and lower inequality on poverty? Specifically, does greater competitiveness increase the impact of higher labor productivity and lower inequality on poverty reduction? In a simple model, we show that there is complementarity between competitiveness and productivity – the greater is one, the larger is the impact of the other. This suggests that improving labor market competitiveness is worthwhile not only for its own sake, but because it improves the transmission mechanism from productivity increases to poverty reduction. We also derive precise conditions under which there is a similar complementarity between equality and competitiveness in poverty reduction.

description: 21 cm intensity mapping has emerged as a promising technique to map the large-scale structure of the Universe. However, the presence of foregrounds with amplitudes orders of magnitude larger than the cosmological signal constitutes a critical challenge. Here, we test the sparsity-based algorithm Generalised Morphological Component Analysis (GMCA) as a blind component separation technique for this class of experiments. We test the GMCA performance against realistic full-sky mock temperature maps that include, besides astrophysical foregrounds, also a fraction of the polarized part of the signal leaked into the unpolarized one, a very troublesome foreground to subtract, usually referred to as polarization leakage. To our knowledge, this is the first time the removal of such component is performed with no prior assumption. We assess the success of the cleaning by comparing the true and recovered power spectra, in the angular and radial directions. In the best scenario looked at, GMCA is able to recover the input angular (radial) power spectrum with an average bias of $\sim 5\%$ for $\ell>25$ ($20 - 30 \%$ for $k_{\parallel} \gtrsim 0.02 \,h^{-1}$Mpc), in the presence of polarization leakage. Our results are robust also when up to $40\%$ of channels are missing, mimicking a Radio Frequency Interference (RFI) flagging of the data. Having quantified the notable effect of polarisation leakage on our results, in perspective we advocate the use of more realistic simulations when testing 21 cm intensity mapping capabilities.

description: The Bent Crystal Spectrometer (BCS) on the NASA Solar Maximum Mission spacecraft observed the X-ray spectra of numerous solar flares during the periods 1980 February to November and 1984~--~1989. The instrument, the first of its kind to use curved crystal technology, observed the resonance lines of He-like Ca (\caxix) and Fe (\fexxv) and neighboring satellite lines, allowing the study of the rapid evolution of flare plasma temperature, turbulence, mass motions etc. To date there has not been a solar X-ray spectrometer with comparable spectral and time resolution, while subsequent solar cycles have delivered far fewer and less intense flares. The BCS data archive thus offers an unparalleled resource for flare studies. A recent re-assessment of the BCS calibration and its operations is extended here by using data during a spacecraft scan in the course of a flare on 1980 November~6 that highlights small deformations in the crystal curvature of the important channel~1 (viewing lines of \caxix\ and satellites). The results explain long-standing anomalies in spectral line ratios which have been widely discussed in the past. We also provide an in-flight estimation of the BCS collimator field of view which improves the absolute intensity calibration of the BCS. The BCS channel~1 background is shown to be entirely due to solar continuum radiation, confirming earlier analyses implying a time-variable flare abundance of Ca. We suggest that BCS high-resolution \caxix\ and \fexxv\ line spectra be used as templates for the analysis of X-ray spectra of non-solar sources.

K(892)* Resonance Production in Au+Au and p+p Collisions at sqrt(sNN) = 200 GeV at RHIC

description: The short-lived $K(892)^{*}$ resonance provides an efficient tool to probe properties of the hot and dense medium produced in relativistic heavy-ion collisions. We report measurements of $K^{*}$ in $\sqrt{s_{_{NN}}}$ = 200 GeV Au+Au and $p+p$ collisions reconstructed via its hadronic decay channels $K(892)^{*0} \to Kπ$ and $K(892)^{*\pm} \to K_S^0π^{\pm}$ using the STAR detector at RHIC. The $K^{*0}$ mass has been studied as a function of $p_T$ in minimum bias $p+p$ and central Au+Au collisions. The $K^{*}$ $p_T$ spectra for minimum bias $p+p$ interactions and for Au+Au collisions in different centralities are presented. The $K^{*}/K$ yield ratios for all centralities in Au+Au collisions are found to be significantly lower than the ratio in minimum bias $p+p$ collisions, indicating the importance of hadronic interactions between chemical and kinetic freeze-outs. A significant non-zero $K^{*0}$ elliptic flow ($v_2$) is observed in Au+Au collisions and compared to the $K_S^0$ and $Λ$ $v_2$. The nuclear modification factor of $K^{*}$ at intermediate $p_{T}$ is similar to that of $K_{S}^{0}$, but different from $Λ$. This establishes a baryon-meson effect over a mass effect in the particle production at intermediate $p_T$ ($2 < p_T \leq 4$ GeV/$c$).

description: Maintaining smallholder competitiveness in the changing market for pigs and pig meat remains an important development challenge, particularly in the context of pro-poor public policymaking. With the ongoing rapid changes in market organizations to respond to changing consumer demand and market requirements, there are viable institutional options and market organizations for smallholders to remain active participants in the pig industry where they are substantially contributing in terms of total output. Results from this study suggest that there is limited scope for smallholder pig producers to participate in formal contracts; however, smallholders were found to participate in informal contracts with cooperatives and with input/output traders that facilitated their access to pig markets. But what drives these smallholders to participate in these types of contractual arrangements for pig and piglet production? A multinomial logit model is applied to reveal the determinants influencing the choice of contractual arrangements by smallholder pig producers in four provinces in Northern Vietnam. Results suggest that the significant determinants of smallholders’ participation in contractual arrangements are age, proportion of time spent in pig-raising, location, distance to veterinary shops, and access to animal health services.

description: A nonmonotonic dependence of the critical Josephson supercurrent on the injection current through a normal metal/ferromagnet weak link from a single domain ferromagnetic strip has been observed experimentally in nanofabricated planar crosslike S-N/F-S Josephson structures. This behavior is explained by 0-pi and pi-0 transitions, which can be caused by the suppression and Zeeman splitting of the induced superconductivity due to interaction between N and F layers, and the injection of spin-polarized current into the weak link. A model considering both effects has been developed. It shows the qualitative agreement between the experimental results and the theoretical model in terms of spectral supercurrent-carrying density of states of S-N/F-S structure and the spin-dependent double-step nonequilibrium quasiparticle distribution.
