description: Farmers reported that 77.8 million pounds (a.i.) of pesticides were applied to soybeans in the North Central States during 1980. This consisted of 77.1 million pounds (a.i.) of herbicides and 700,000 pounds (a.i.) of insecticides. Pesticide acre—treatments totaled 58.1 million and consisted of 44.8 million with single material herbicides, 12.6 million with herbicide mixes, and 700,000 with insecticides. The primary herbicides were alachlor, bentazon, metribuzin, and trifluralin. The major insecticide was carbaryl. Herbicides were applied primarily to control cocklebur, foxtail, and velvetleaf infestations. Most insecticides were applied for armyworm, bean leaf beetle, corn earworm, grass— hopper, and Mexican bean beetle control. Coefficients of variation were computed for acres of soybeans treated with specific pesticide materials.

Tag N' Train: A Technique to Train Improved Classifiers on Unlabeled Data

description: There has been substantial progress in applying machine learning techniques to classification problems in collider and jet physics. But as these techniques grow in sophistication, they are becoming more sensitive to subtle features of jets that may not be well modeled in simulation. Therefore, relying on simulations for training will lead to sub-optimal performance in data, but the lack of true class labels makes it difficult to train on real data. To address this challenge we introduce a new approach, called Tag N' Train (TNT), that can be applied to unlabeled data that has two distinct sub-objects. The technique uses a weak classifier for one of the objects to tag signal-rich and background-rich samples. These samples are then used to train a stronger classifier for the other object. We demonstrate the power of this method by applying it to a dijet resonance search. By starting with autoencoders trained directly on data as the weak classifiers, we use TNT to train substantially improved classifiers. We show that Tag N' Train can be a powerful tool in model-agnostic searches and discuss other potential applications.

description: This bibliography identifies some of the important literature on the economic and related aspects of irrigation, with special but not exclusive reference to the humid regions of the Eastern United States. The bibliography is categorized under three main headings: on-farm irrigation planning; state, regional, geographic, and economic assessments; and national irrigation and selected policy assessments. To account for distinctive climatic variations reflected in irrigated cropland patterns in the Eastern States, four specific agricultural areas are given intensive treatment, including Florida, the Delmarva Peninsula, southern New Jersey, and Minnesota.
SPH simulations of Shakura-Sunyaev instability at intermediate accretion rates

description: We show that a standard Shakura-Sunyaev accretion disc around a black hole with an accretion rate lower than the critical Eddington limit does show the instability in the radiation pressure dominated zone. We obtain this result performing time-dependent simulations of accretion disks for a set of values of the viscosity parameter and accretion rate. In particular we always find the occurrence of the collapse of the disc: the instability develops always towards a collapsed gas pressure dominated disc and not towards the expansion. This result is valid for all initial configurations we tested. We find significant convective heat flux that increases the instability development time, but is not strong enough to inhibit the disc collapse. A physical explanation of the lack of the expansion phase is proposed considering the role of the radial heat advection. Our finding is relevant since it excludes the formation of the hot comptonizing corona -often suggested to be present- around the central object by the mechanism of the Shakura-Sunyaev instability. We also show that, in the parameters range we simulated, accretion disks are crossed by significant amplitude acoustic waves.

description: Partial quorum systems are widely used in distributed key-value stores due to their latency benefits at the expense of providing weaker consistency guarantees. The probabilistically bounded staleness framework (PBS) studied the latency-consistency trade-off of Dynamo-style partial quorum systems through Monte Carlo event-based simulations. In this paper, we study the latency-consistency trade-off for such systems analytically and derive a closed-form expression for the inconsistency probability. Our approach allows fine-tuning of latency and consistency guarantees in key-value stores, which is intractable using Monte Carlo event-based simulations.

description: Foreigners awned 12.7 million acres of U.S. agricultural land as of December 31, 1981. This is slightly less than 1 percent of all privately held agricultural land and 0.6 percent of all land in the United States. This share is too small to measure the impact on agriculture at the national level. However, some communities in areas of heaviest concentration could be affected. These findings are based on an analysis of reports submitted in compliance with the Agricultural Foreign Investment Disclosure Act of 1978.

description: We studied the electronic band structure of pulsed laser deposition (PLD) grown (111)-oriented SrRuO$_3$ (SRO) thin films using \textit{in situ} angle-resolved photoemission spectroscopy (ARPES) technique. We observed previously unreported, light bands with a renormalized quasiparticle effective mass of about 0.8$m_{e}$. The electron-phonon coupling underlying this mass renormalization yields a characteristic "kink" in the band dispersion. The self-energy analysis using the Einstein model suggests five optical phonon modes covering an energy range 44 to 90 meV contribute to the coupling. Besides, we show that the quasiparticle spectral intensity at the Fermi level is considerably suppressed, and two prominent peaks appear in the valance band spectrum at binding energies of 0.8 eV and 1.4 eV, respectively. We discuss the possible implications of these observations. Overall, our work demonstrates that high-quality thin films of oxides with large spin-orbit coupling can be grown along the polar (111) orientation by the PLD technique, enabling \textit{in situ} electronic band structure study. This could allow for characterizing the thickness-dependent evolution of band structure of (111) heterostructures$-$a prerequisite for exploring possible topological quantum states in the bilayer limit.

description: Inelastic light-scattering spectra of underdoped ${\rm La_{2-x}Sr_xCuO_4}$ (LSCO) single crystals are presented which provide direct evidence of the formation of quasi one-dimensional charged structures in the two-dimensional $\rm CuO_2$ planes. The ``stripes'' manifest themselves in a Drude-like peak at low energies and temperatures. The selection rules allow us to determine the orientation to be along the diagonals at $x=0.02$ and along the principal axes at $x=0.10$. The electron-lattice interaction determines the correlation length which turns out to be larger in compound classes with lower superconducting transition temperatures. Temperature is the only scale of the response at different doping levels demonstrating the importance of quantum critical behavior.

Uncertainty Principle for Communication Compression in Distributed and Federated Learning and the Search for an Optimal Compressor

description: In order to mitigate the high communication cost in distributed and federated learning, various vector compression schemes, such as quantization, sparsification and dithering, have become very popular. In designing a compression method, one aims to communicate as few bits as possible, which minimizes the cost per communication round, while at the same time attempting to impart as little distortion (variance) to the communicated messages as possible, which minimizes the adverse effect of the compression on the overall number of communication rounds. However, intuitively, these two goals are fundamentally in conflict: the more compression we allow, the more distorted the messages become. We formalize this intuition and prove an {\em uncertainty principle} for randomized compression operators, thus quantifying this limitation mathematically, and {\em effectively providing asymptotically tight lower bounds on what might be achievable with communication compression}. Motivated by these developments, we call for the search for the optimal compression operator. In an attempt to take a first step in this direction, we consider an unbiased compression method inspired by the Kashin representation of vectors, which we call {\em Kashin compression (KC)}. In contrast to all previously proposed compression mechanisms, KC enjoys a {\em dimension independent} variance bound for which we derive an explicit formula even in the regime when only a few bits need to be communicate per each vector entry.

description: Beyond future applications, quantum networks open interesting fundamental perspectives, notably novel forms of quantum correlations. In this work we discuss quantum correlations in networks from the perspective of the underlying quantum states and their entanglement. We address the questions of which states can be prepared in the so-called triangle network, consisting of three nodes connected pairwise by three sources. We derive necessary criteria for a state to be preparable in such a network, considering both the cases where the sources are statistically independent and classically correlated. This shows that the network structure imposes strong and non-trivial constraints on the set of preparable states, fundamentally different from the standard characterization of multipartite quantum entanglement.

description: Both price incentives and increases in efficiency have been responsible for increased livestock production and feed use in the European Community. Econometric estimates from 1964 to 1979 suggest that increased efficiency was a more important factor for poultry meat, eggs, and pork, while price incentives were more important for beef and dairy. Feed demand for grains and oilseed meal responded mainly to the growth in livestock products, but was limited by increases in the use of nongrain feeds. Simulation results suggest that lower price supports would have significantly reduced milk production and feed use, while an increase in the price of oilseed meals would have had little effect on the demand for total oilseed meal.

description: Currently, the University of British Columbia (UBC) Wellness Centre’s nutrition resources are not being used by UBC students as much as desired (Stevens, H., Personal Communication, January 21, 2019). Our community partner, the UBC Wellness Centre, would like to find new ways to offer nutrition resources that will fit the needs and wants of students, with the hope of encouraging more students to use these resources. The main goal of this project is to provide the UBC Wellness Centre with information about how nutrition-related resources can capture the interest of UBC students. In collaboration with the UBC Wellness Centre and SEEDS Sustainability Program, our team developed a survey using the Qualtrics Survey software and distributed it through our individual social media accounts, posters, class announcements, and in-person with an iPad. The results of our study showed that most students prefer to learn about practical cooking skills and also prefer their resources to be easily accessible and readily available. Among other formats, websites and workshops were mentioned as the preferred style of learning. Although this sample size was not representative of the whole UBC student population, the information from these responses can provide the UBC Wellness Centre with an idea of what some students are interested in. Our team was successful in meeting most of our short-term objectives, which included completing a Qualtrics survey by mid-February and providing a summary of our relevant data to the UBC Wellness Centre. The one short-term objective that we did not meet was to collect 200 survey responses, since we were only able to collect a total of 160 responses within our time limit. The success of this project will continue to be evaluated by measuring changes in attendance at nutrition workshops and the utilization rate of nutritional resources in the future. Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community.

Non Local Theories: New Rules for Old Diagrams

description: We show that a general variant of the Wick theorems can be used to reduce the time ordered products in the Gell-Mann & Low formula for a certain class on non local quantum field theories, including the case where the interaction Lagrangian is defined in terms of twisted products. The only necessary modification is the replacement of the Stueckelberg-Feynman propagator by the general propagator (the ``contractor'' of Denk and Schweda) D(y-y';tau-tau')= - i (Delta_+(y-y')theta(tau-tau')+Delta_+(y'-y)theta(tau'-tau)), where the violations of locality and causality are represented by the dependence of tau,tau' on other points, besides those involved in the contraction. This leads naturally to a diagrammatic expansion of the Gell-Mann & Low formula, in terms of the same diagrams as in the local case, the only necessary modification concerning the Feynman rules. The ordinary local theory is easily recovered as a special case, and there is a one-to-one correspondence between the local and non local contributions corresponding to the same diagrams, which is preserved while performing the large scale limit of the theory.

description: The milking operation is the most labor intensive activity in milk production. Labor costs, expressed as a percent of total milking system costs, may run as high as 82 percent for smaller, less mechanized systems [3]. Due to the high labor requirement for milking, dairymen have typically viewed, with considerable interest, the capital-labor tradeoffs associated with different parlors and with varying levels of mechanization on particular parlors. That interest has intensified in recent years due to rising labor costs, greater difficulty in finding and retaining competent milkers, larger herds, and new mechanization alternatives.

description: The Frauchiger-Renner Paradox is an extension of paradoxes based on the 'Problem of Measurement,' such as Schrodinger's Cat and Wigner's Friend. All of these paradoxes stem from assuming that quantum theory has only unitary (linear) physical dynamics, and the attendant ambiguity about what counts as a 'measurement'--i.e., the inability to account for the observation of determinate measurement outcomes from within the theory itself. This paper discusses a basic inconsistency arising in the FR scenario at a much earlier point than the derived contradiction: namely, the inconsistency inherent in treating an improper mixture (reduced density operator) as a proper, epistemic mixture. This is an illegitimate procedure that is nevertheless endemic if quantum theory is assumed to be always unitary. In contrast, under a non-unitary account of quantum state reduction yielding determinate outcomes, the use of a proper mixture for measurement results becomes legitimate, and this entire class of paradoxes cannot be mounted. The conclusion is that the real lesson of the FR paradox is that it is the unitary-only assumption that needs to be critically reassessed.

description: Land and water uses for a 32—county area in southwest Georgia in 1979 were identified and projected to 1990. An "ongoing" and an "accelerated" land treatment pro— gram to reduce erosion and curb sediment delivery from cropland were evaluated. With a moderate expansion in irrigation, net returns for six major crops plus small grains in 1990 were estimated at $240.7 and $257.9 million per year with the ongoing and accelerated pro— grams, respectively, compared with the 1979 base year net return of $159.4 million.

description: We report the discovery of large scale structures of X-ray sources in the 1Msec observation of the Chandra Deep Field South. Two main structures appear as narrow (Delta_z < 0.02) spikes in the source redshift distribution at z=0.67 and z=0.73, respectively. Their angular distribution spans a region at least ~ 17 arcmin wide, corresponding to a physical size of 7.3 h_{70}^{-1} Mpc at a redshift of z ~ 0.7 (Omega_m=0.3, Omega_{Lambda}=0.7). These spikes are populated by 19 sources each, which are mainly identified as Active Galactic Nuclei (AGN). Two sources in each spike are extended in X-rays, corresponding to galaxy groups/clusters embedded in larger structures. The X-ray source redshift distribution shows other spikes, the most remarkable at z=1.04, 1.62 and 2.57. This is one of the first evidences for large scale structure traced by X-ray sources and for spatial clustering of X-ray selected AGN. The X-ray data have been complemented with the spectroscopic data from the K20 near infrared survey (Cimatti et al. 2002), which covers ~1/10 of the X-ray field. Also in this survey the source redshift distribution shows several spikes. Two narrow structures at z=0.67 and z=0.73 (again with Delta_z ~ 0.02) are the most significant features, containing 24 and 47 galaxies, respectively. While the K20 structure at z=0.73 is dominated by a standard galaxy cluster with a significant concentration around a central cD galaxy and morphological segregation, the galaxies at z=0.67 constitute a loose structure rather uniformly distributed along the K20 field.[abridged]

description: Australia is a major producer and exporter of beef and veal. In 1982, Australia exported 628 kilotons of beef and veal valued at US$1,177 million. Half of Australia's beef and veal was imported by the United States and Japan. The Australian cattle industry depends on grazing; consequently, number of cattle, slaughter, and production have fluctuated considerably from droughts, diseases, cattle cycles, and changing export markets. The United States and Australia significantly affect one another's beef industries. The United States influences the Australian beef and veal industry indirectly through beef cycle price changes, and directly through the Countercyclical Meat Import Law. Australia will continue to compete strongly with the United States in beef export markets.

description: This article investigates estimation of sparsity-induced weak factor (sWF) models, with large cross-sectional and time-series dimensions (N and T, respectively). It assumes that the kth largest eigenvalue of a data covariance matrix grows proportionally to Nαk with unknown exponents 0<αk≤1 for k=1,…,r. Employing the same rotation of the principal components (PC) estimator, the growth rate αk is linked to the degree of sparsity of kth factor loadings. This is much weaker than the typical assumption on the recent factor models, in which all the r largest eigenvalues diverge proportionally to N. We apply the method of sparse orthogonal factor regression (SOFAR) by Uematsu et al. (2019) to estimate the sWF models and derive the estimation error bound. Importantly, our method also yields consistent estimation of αk. A finite sample experiment shows that the performance of the new estimator uniformly dominates that of the PC estimator. We apply our method to forecasting bond yields and the results demonstrate that our method outperforms that based on the PC. We also analyze S&P500 firm security returns and find that the first factor is consistently near strong while the others are weak.

description: Low mass X-ray binaries (LMXBs) containing neutron stars are both extremely luminous and compact, emitting up to ~10^6 L_sun within a kilometer-scale boundary layer. This combination allows for easy modulation, motivating X-ray SETI. When X-ray lenses with radii 100--1,000 km magnify the LMXB boundary layer, it brightens by a factor of several thousand for a fraction of a second. In addition, there should be occultation events where the neutron star is blocked out. Passive X-ray lenses could require little internal power and the LMXB light source itself shines for millions of years, with potential for an effective beacon for interstellar communication. A very large number of lenses would be needed to ensure frequent signals in all directions, however, and gathering material to construct them could be very difficult. Avoiding collisions between lenses, aiming them, and building and maintaining their precise shapes pose additional challenges. "Lens flares" of bright LMXBs are easily detectable in the Galaxy, although they would be rare events, occurring perhaps once per decade. Our sensitive X-ray instruments could detect the eclipses of Galactic LMXBs and possibly intergalactic flares, but it is unlikely they would be observing the LMXB at the right time.

How "cold" are the stellar discs of superthin galaxies?

description: Superthin galaxies are a class of bulgeless, low surface brightness galaxies with strikingly high values of planar-to-vertical axes ratio $\rm(b/a> 10 - 20)$, possibly indicating the presence of an ultra-cold stellar disc. Using the multi-component galactic disc model of gravitationally-coupled stars and gas in the force field of the dark matter halo as well as the stellar dynamical code AGAMA (Action-based Galaxy Modelling Architecture), we determine the vertical velocity dispersion of stars and gas as a function of galacto-centric radius for five superthin galaxies (UGC 7321, IC 5249, FGC 1540, IC2233 and UGC00711) using observed stellar and atomic hydrogen (HI) scale heights as constraints, using a Markov Chain Monte Carlo Method. We find that the central vertical velocity dispersion for the stellar disc in the optical band varies between $σ_{0s}$ $\sim$ $10.2 - 18.4$ $\rm{kms}^{-1}$ and falls off with an exponential scale length of $2.6$ to $3.2$ $R_{d}$ where $R_{d}$ is the exponential stellar disc scale length. Interestingly, in the 3.6 $μ$m, the same, averaged over the two components of the stellar disc, varies between $5.9$ to $11.8$ $\rm{kms}^{-1}$, both of which confirm the presence of "ultra-cold" stellar discs in superthin galaxies. Interestingly, the global median of the multi-component disc dynamical stability parameter $Q_N$ of our sample superthins is found to be 5 $\pm$ 1.5, which higher than the global median value of 2.2 $\pm$ 0.6 for a sample of spiral galaxies.

description: In this paper we will attempt an analysis of some of the economic questions that emerge because of variable environments genotype environment interactions and the selection and crossing options open to the crop-breeder. In the first section of the paper we will discuss the concepts of stability and adaptability as they relate to the problem. The second section of the paper then presents a model of optimal targeting of crop-breeding activities. The final section offers some empirical evidence regarding stability and adaptability in wheat genotypes.

description: We present an extension of the JHUGen and MELA framework, which includes an event generator and library for the matrix element analysis. It enables simulation, optimal discrimination, reweighting techniques, and analysis of a bosonic resonance and the triple and quartic gauge boson interactions with the most general anomalous couplings. The new features, which become especially relevant at the current stage of LHC data taking, are the simulation of gluon fusion and vector boson fusion in the off-shell region, associated $ZH$ production at NLO QCD including the $gg$ initial state, and the simulation of a second spin-zero resonance. We also quote translations of the anomalous coupling measurements into constraints on dimension-six operators of an effective field theory. Some of the new features are illustrated with projections for experimental measurements with the full LHC and HL-LHC datasets.
