description: This paper integrates economic and physical models to assess how federal crop revenue insurance programs might affect land use, cropping systems, and environmental quality in the U.S. Corn Belt region. The empirical framework includes econometric models that predict land conversion, crop choices, and crop rotations at the parcel level based on expectation and variance of crop revenues, land quality, climate conditions, and physical characteristics at each site. The predictions are then combined with site-specific environmental production functions to determine the effect of revenue insurance on nitrate runoff and leaching, soil water and wind erosion, and carbon sequestration. Results suggest that crop insurance will have small impacts on conversions of non-cropland to cropland, but more significant impacts on crop choice. These changes in crop mix have moderate impacts on agricultural pollution.

description: A cropland retirement policy contributes to the reduction of environmental externalities from agricultural production such as soil erosion, nutrient runoff and loss of wildlife habitat. On the other hand, participant's potential adverse behavior could undermine the environmental benefits of the policy. Several sources of such an unintended effect, known as “slippage", have been conceptually identified, but their empirical evidence has been scarce. This article tests one source of slippage caused by in-farm land substitution from noncropland to cropland as a result of farmland retirement in the U.S. Conservation Reserve Program (CRP). With the farm-level longitudinal data I can utilize cross-sectional and time variation of detailed individual farm characteristics to identify the causal relationship of CRP participation and subsequent slippage through in-farm land substitution. An identified assumption of the slippage estimate is verified by farm fixed effects, time-varying county fixed effects, and selection-on-observables. These could eliminate effects of unobservables that are potentially correlated with both the program participation and subsequent farmland reallocation decisions. Overall, slippage seems evident and fairly robust among specifications. It is found that an average program participant converts 14% of noncropland to cropping activities after enrollment. Results further show that participants with a larger share of uncropped land contribute more to slippage, indicating that farms with the excess capacity of conversion are more exible in the land allocation decision and thus likely to give rise to slippage. This suggests that additional restrictions on the rest of land use for participants and/or introduction of penalty points reecting the share of noncropland in the current auction mechanism can hinder such a backward incentive offsetting the program benefits.

description: We determine the Milky Way (MW) mass profile inferred from fitting physically motivated models to the Gaia DR2 Galactic rotation curve and other data. Using various hydrodynamical simulations of MW-mass haloes, we show that the presence of baryons induces a contraction of the dark matter (DM) distribution in the inner regions, r<20 kpc. We provide an analytic expression that relates the baryonic distribution to the change in the DM halo profile. For our galaxy, the contraction increases the enclosed DM halo mass by factors of roughly 1.3, 2 and 4 at radial distances of 20, 8 and 1 kpc, respectively compared to an uncontracted halo. Ignoring this contraction results in systematic biases in the inferred halo mass and concentration. We provide a best-fitting contracted NFW halo model to the MW rotation curve that matches the data very well. The best-fit has a DM halo mass, $M_{200}^{\rm DM}=0.97_{-0.19}^{+0.24}\times10^{12} M_\odot$, and concentration before baryon contraction of $9.4_{-2.6}^{+1.9}$, which lie close to the median halo mass--concentration relation predicted in $Λ$CDM. The inferred total mass, $M_{200}^{\rm total}=1.08_{-0.14}^{+0.20} \times 10^{12} M_\odot$, is in good agreement with recent measurements. The model gives a MW stellar mass of $5.04_{-0.52}^{+0.43}\times10^{10} M_\odot$ and infers that the DM density at the Solar position is $ρ_{\odot}^{\rm DM}=8.8_{-0.5}^{+0.5}\times10^{-3} M_\odot \rm{pc}^{-3}\equiv0.33_{-0.02}^{+0.02}~\rm{GeV}~\rm{cm}^{-3}$. The rotation curve data can also be fitted with an uncontracted NFW halo model, but with very different DM and stellar parameters. The observations prefer the physically motivated contracted NFW halo, but the measurement uncertainties are too large to rule out the uncontracted NFW halo.

description: Additional file 1: Figure S1. A sandwich immunoassay which captured the conventionally (conv.) spliced or frameshifted C-terminus of the XBP1 isoforms and a pan-detector of the common N-terminus was designed. Due to the unconventional splicing of XBP1 mRNA a translational frameshift occurs and results in XBP1 isoforms of differing length and C-terminal sequences (A). A biochip was proposed that utilised these different C-termini for simultaneous capture and the common N-terminus for detection (B).

description: We consider the problem of condensation of open string tachyon fields which have an O(D) symmetric profile. This problem is described by a boundary conformal field theory with D scalar fields on a disc perturbed by relevant boundary operators with O(D) symmetry. The model is exactly solvable in the large D limit and we analyze its 1/D expansion. We find that this expansion is only consistent for tachyon fields which are polynomials. In that case, we show that the theory is renormalized by normal ordering the interaction. The beta-function for the tachyon field is the linear wave operator. We derive an expression for the tachyon potential and compare with other known expressions. In particular, our technique gives the exact potential for the quadratic tachyon profile. It can be used to correct the action which has been derived in that case iteratively in derivatives of the tachyon field.

description: The response of farmers to crop insurance incentives has been studied extensively. In particular, studies following the landmark ARPA legislation in 2000 have taken a close look at farmer participation changed with changes in the insurance subsidies. However, few if any studies have looked at the extent of farmer participation as measured in terms of their choice of coverage levels. This analysis uses farm-level observations of crop insurance choices to examine how changes to premium rates and subsidies may affect farmer choice of insurance coverage levels. Specifically we examine farmer choices of from a set of discrete coverage levels to changes in insurance premium subsidies that occurred in 2008 and 2009 while accounting for farm characteristics and market conditions. Some portion of the farmer choice of coverage levels were due to policy choices in the 2008 Farm Bill, whereas others were a result of significant price or other market changes between 2008 and 2009.

description: A seismic model for the Sun calculated using the accurate helioseismic data predicts a lower $^{8}{B}$ neutrino flux as compared to the standard solar model (SSM). However, there persists a discrepancy between the predicted and measured neutrino fluxes and it seems necessary to invoke neutrino oscillations to explain the measurements. In this work, we have performed a global, unified oscillation analysis of the latest solar neutrino data (including the results of SNO charged current rate) using the seismic model fluxes as theoretical predictions. We determine the best-fit values of the neutrino oscillation parameters and the $χ^2_{\mathrm min}$ for both $ν_e-ν_{\mathrm active}$ and $ν_e -ν_{\mathrm sterile}$ cases and present the allowed parameter regions in the $Δm^2 - \tan^2 θ$ plane for $ν_e-ν_{\mathrm active}$ transition. The results are compared with those obtained using the latest SSM by Bahcall and his collaborators.

description: Carbon nanotubes are of central importance for applications in nano-electronics thanks to their exceptional transport properties. They can be used as sensors, for example in biological applications, provided that they are functionalized to detect specific molecules. Due to their one-dimensional geometry the carbon nanotubes are very sensitive to the phenomenon of Anderson localization and it is therefore essential to know how the functionalization modifies their conduction properties and if they remain good conductors. Here we present a study of the quantum localization induced by functionalization in metallic single walled carbon nanotubes (SWCNT) with circumferences up to $ 15\; nm $. We consider resonant and non-resonant adsorbates that represent two types of covalently functionalized groups with moderate and strong scattering properties. The present study provides a detailed analysis of the localization behaviour and shows that the localization length can decrease down to $ 20-50\; nm $ at concentrations of about 1 percent of adsorbates. On this basis we discuss the possible electronic transport mechanisms which can be either metallic like or insulating like with variable range hopping.

description: Motivated by the recent discovery of superconductivity in the Sr-doped layered nickelate NdNiO$_2$, we perform a systematic computational materials design of layered nickelates that are dynamically stable and whose electronic structure better mimics the electronic structure of high-$T_c$ cuprates than NdNiO$_2$. While the Ni $3d$ orbitals are self-doped from the $d^9$ configuration in NdNiO$_2$ and the Nd-layer states form Fermi pockets, we find more than 10 promising compounds for which the self-doping is almost or even completely suppressed. We derive effective single-band models for those materials and find that they are in the strongly-correlated regime. We also investigate the possibility of palladate analogues of high-$T_c$ cuprates. Once synthesized, these nickelates and palladates will provide a firm ground for studying superconductivity in the Mott-Hubbard regime of the Zaanen-Sawatzky-Allen classification.

description: The Hamiltonian reduction of SU(2) Yang-Mills theory for an arbitrary θangle to an unconstrained nonlocal theory of a self-interacting positive definite symmetric 3 \times 3 matrix field S(x) is performed. It is shown that, after exact projection to a reduced phase space, the density of the Pontryagin index remains a pure divergence, proving the θindependence of the unconstrained theory obtained. An expansion of the nonlocal kinetic part of the Hamiltonian in powers of the inverse coupling constant and truncation to lowest order, however, lead to violation of the θindependence of the theory. In order to maintain this property on the level of the local approximate theory, a modified expansion in the inverse coupling constant is suggested, which for a vanishing θangle coincides with the original expansion. The corresponding approximate Lagrangian up to second order in derivatives is obtained, and the explicit form of the unconstrained analogue of the Chern-Simons current linear in derivatives is given. Finally, for the case of degenerate field configurations S(x) with rank|S| = 1, a nonlinear σ-type model is obtained, with the Pontryagin topological term reducing to the Hopf invariant of the mapping from the three-sphere S^3 to the unit two-sphere S^2 in the Whitehead form.

description: We prove that the local $\mathbb{A}^1$-degree of a polynomial function at an isolated zero with finite separable residue field is given by the trace of the local $\mathbb{A}^1$-degree over the residue field. This fact was originally suggested by Morel's work on motivic transfers and by Kass and Wickelgren's work on the Scheja-Storch bilinear form. As a corollary, we generalize a result of Kass and Wickelgren's relating the Scheja-Storch form and the local $\mathbb{A}^1$-degree.

Spectroscopic Studies and Molecular Dynamics Simulations of Mononuclear Dioxygen Activation Enzymes

Publisher: name: Carnegie Mellon University

Subjects: subject: 30201 Bioinorganic Chemistry

description: The dioxygen activation enzymes are ubiquitous in plants, animals, and microorganisms. These enzymes perform the reactions that propel the circulation of oxygen atoms on the planet. The dioxygen molecule supports many critical biochemical processes strictly regulated by enzymes, which in many cases are metalloenzymes. The iron-containing enzymes are very common in performing dioxygen activation. Among them, the mononuclear non-heme iron (MNHI) enzymes, constituting a large subcategory, are capable of performing various types of reactions using the mono-iron center. The mechanistic investigation of the MNHI enzymes is the main subject of this thesis.The iron (II) and 2-oxoglutarate (Fe/2OG) dependent enzyme is a subfamily of MNHI enzymes that use 2OG as co-substrate for dioxygen activation. The Fe/2OG enzymes are proposed to have conserved mechanisms for the initial dioxygen activation reaction with 2OG. We investigate different Fe/2OG enzymes to reconstruct the potential reaction pathways after the initial reaction with dioxygen. We also investigate the effect of different 2OG binding configurations to the iron center on the dioxygen activation. Besides the Fe/2OG enzymes, we investigate a co-substrate independent MNHI enzyme to explore the mechanism that leads to novel reactivity.The investigation of iron-containing enzymes shows a historical trend, where the research focus is initially on the heme enzymes, followed by Fe/2OG MNHI enzymes, and then co-substrate independent MNHI enzymes. In this sequence, the versatility of the mononuclear iron center is gradually untamed. The heme enzymes install a rigid porphyrin frame to fix the iron, in which the iron has very limited flexibility. The Fe/2OG enzymes coordinate the Fe through protein residues and 2OG, such that variation of residues and different configurations of 2OG introduces more flexibility. The co-substrate independent MNHI enzymes delegate the initial dioxygen activation from 2OG to the substrate, therefore the substrate can use the initial dioxygen activation step together with the subsequent oxidation steps to perform complex reactions. The research in this thesis will advance the understanding of dioxygen activation in iron-containing enzymes and the mechanism that couples dioxygen activation with various enzymatic reactivity.

description: Local and regional risk management programs imply different results than the existing emphasis of public management on a chemical by chemical, source by source basis for social control. Local multi-hazard risk management programs are beginning to be encouraged, are complementary to existing policy and, on the whole, are desirable. Indeed such local risk management programs could play a key role in preserving the integrity of rural groundwater resources. The issue of the triage problem, or whether contamination of some waters from agricultural chemicals is inevitable and therefore should be planned for rationally, is examined from the point of view of general administration of pollution control.

description: We set up a set of many-body kinetic Bloch equations with spacial inhomogeneity. We reexamine the widely adopted quasi-independent electron model (QIEM) and show the inadequacy of this model in studying the spin transport. We further point out a new decoherence effect based on interference effect of electrons/spins with different momentum ${\bf k}$ along the direction of the diffusion, which is referred as ``inhomogeneous broadening effect'' in our paper. We show that this inhomogeneous broadening can cause spin decoherence alone even in the absence of the scattering and that the resulting decoherence can be more important than the dephasing effect due to the D'yakonov-Perel' (DP) term together with the scattering. Our theory takes all the inhomogeneous broadening effect, the spin diffusion due to the spacial inhomogeneity and the spin dephasing into account and gets the results self-consistently. We further study the spin diffusion/transport of an $n$-typed GaAs quantum well (QW) in the steady state under different conditions, such as at different temperatures; in the presence of impurities; in the presence of external electric fields along the diffusion direction and/or the QW growth direction; and with magnetic fields in the Voigt configuration. We also demonstrate a time evolution of a spin package calculated from our many-body theory. Different features predicted from our many-body theory are highlighted in the paper.

description: The radial velocity (RV) is a basic physical quantity which can be determined through Doppler shift of the spectrum of a star. The precision of RV measurement depends on the resolution of the spectrum we used and the accuracy of wavelength calibration. In this work, radial velocities of LAMOST-II medium resolution (R ~ 7500) spectra are measured for 1,594,956 spectra (each spectrum has two wavebands) through matching with templates. A set of RV standard stars are used to recalibrate the zero point of the measurement, and some reference sets with RVs derived from medium/high-resolution observations are used to evaluate the accuracy of the measurement. Comparing with reference sets, the accuracy of our measurement can get 0.0227 km s/1 with respect to radial velocities standard stars. The intrinsic precision is estimated with the multiple observations of single stars, which can achieve to 1.36 km s/1,1.08 km s/1, 0.91 km s/1 for the spectra at signal-to-noise levels of 10, 20, 50, respectively.

description: The effect of negative publicity on consumer demand for brands is examined in the context of recall of a peanut butter brand as a result of pathogen contamination. The recall was asso- ciated with negative impacts for the implicated brand and positive effects on the leading competitor brand. Consumers responded to the foodborne illness outbreak within three weeks. The case demonstrates that consumer response is an incentive for companies to prevent safety lapses and that the problems of one brand do not necessarily harm rivals within the category.
Understanding the Sources and Transformations of Ice Nucleating Particles and Trace Reactive Gases in Biomass-Burning Emissions
Creators: name: Jahl, Lydia
Publisher: name: Carnegie Mellon University
Year: 2021
Subjects: Environmental Chemistry

description: The ability of a very small fraction of particulate matter to act as ice nucleating particles and initiate cloud glaciation has important impacts on cloud microphysics, precipitation, radiative forcing, and climate change. In recent years, the Sullivan group has investigated biomass-burning aerosol as a source of ice nucleating particles. My contributions towards measuring the aerosol chemical composition using aerosol mass spectrometry throughout biomass-burning experiments has improved our understanding of how atmospheric chemical aging influences the ice-nucleation activity of biomass-burning aerosol. We discovered that as biomass-burning aerosol ages, organic matter on the particle surfaces can evaporate or dissolve to reveal preexisting mineral-based ice-active sites, increasing the overall ability of biomass-burning aerosol to nucleate ice as it is undergoes transport and aging throughout the atmosphere. Some aging mechanisms, such as ozonolysis, result in the production of secondary organic aerosol which can have the opposite effect and result in no change or even a decrease in the ice-nucleation activity. While previous literature exists regarding how the ice activity of some types of ice nucleating particles change with atmospheric aging, no other work has investigated biomass-burning aerosol to the extent that my research has. My work introduces a new framework for the evolution of ice nucleating particles from biomass burning where the aerosol becomes more ice active as the smoke plume dilutes with transport. This results in a larger contribution to the ice nucleating particle budget, the resulting cloud microphysics, and climate forcing induced by wildfires than is currently considered.

description: Conservation treatments may cause alterations to the aesthetic qualities and appearance of paper materials, including their color. The scientific evaluation of color change to measure the effects of conservation treatments is therefore valuable information for the conservator weighing the advantages and disadvantages of the various treatments and approaches available. In this study, two Japanese tissue papers (Yukyu-shi and Sekishu Mare) were treated with plant dyes including black tea, henna, fresh and dried Eucalyptus cinerea leaves, as well as selected watercolors and acrylic paints. Paper specimens were subjected to both moist-heat artificial aging and accelerated photo-aging and color changes were measured using spectrophotometry and microfading tests. Color change is here defined as a change in light/dark, red/green, and yellow/blue coordinates in the International Commission on Illumination (CIE) color space of light reflected from a colored surface before and after an intervention such as accelerated aging. The findings of this study show that paper samples treated with plant dyes experienced larger and more perceptible color changes, as measured by spectrophotometry, compared to untreated controls and samples treated with watercolors and acrylic paints. Thus, plant dyes have poor color stability after moist-heat aging when compared with watercolors and acrylic paints. Nevertheless, papers treated with alizarin crimson acrylic paint, dried eucalyptus leaves, and black tea exhibited minimal color change after photo-aging. This study provides paper conservators with a better understanding of toning materials and their color stability when chosen for paper conservation treatment.

description: Earlier described model amplitudes are used in this paper to evaluate both cross sections and density matrices for two-photon mediated resonance production in e^+e^- collisions. All 25 q\bar{q} low-lying ^1S_0, ^3P_J and ^1D_2 resonances can thus be treated. Two independent methods are described to obtain the resonance production density matrices and cross sections. These density matrices combined with a resonance decay density matrix give the detailed angular distributions of the resonance decay products. For two particular decays, χ_{c2},χ_{c1}\toγJ/ψthe details are given. Several numerical results are presented as well.

description: We present a model based on a dipole picture with a hard and a soft pomeron in which large dipoles couple to the soft pomeron and small dipoles couple to the hard pomeron. The parameters in the model are fixed by proton-proton scattering and the proton structure function. The model is then applied successfully to the proton charm structure function, the proton longitudinal structure function, J/psi photoproduction, deep virtual Compton scattering, the real photon-proton total cross section, the real photon-photon cross section, and the photon structure function. Differences between our predictions and data on charm production in real photon-photon interactions and the virtual gamma-gamma cross section are discussed.

Cosmological Creation of D-branes and anti-D-branes

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

description: We argue that the early universe may be described by an initial state of space-filling branes and anti-branes. At high temperature this system is stable. At low temperature tachyons appear and lead to a phase transition, dynamics, and the creation of D-branes. These branes are cosmologically produced in a generic fashion by the Kibble mechanism. From an entropic point of view, the formation of lower dimensional branes is preferred and $D3$ brane-worlds are exponentially more likely to form than higher dimensional branes. Virtually any brane configuration can be created from such phase transitions by adjusting the tachyon profile. A lower bound on the number defects produced is: one D-brane per Hubble volume.

description: This article investigates the extent to which national brand and private label (store brand) prices behave differently as food price inflation changes. Empirical tests using a range of indices support the hypotheses that rising commodity and fuel prices lead to relatively larger surges in private label prices. When food prices are rising or high, the average price dif- ference between national brands and private labels shrinks. The findings have implications for understanding the welfare effects of private labels. Moreover, they suggest that food price inflation is stronger for low-income households as food prices rise.
Excision and avoiding the use of boundary conditions in numerical relativity

description: A procedure for evolving hyperbolic systems of equations on compact computational domains with no boundary conditions was recently described in [arXiv:1905.08657]. In that proposal, the computational grid is expanded in spacelike directions with respect to the outermost characteristic and initial data is imposed on the expanded grid boundary. We discuss a related method that removes the need for imposing boundary conditions: the computational domain is excised along a direction spacelike with respect to the innermost going characteristic. We compare the two methods, and provide example evolutions from a code that implements the excision method: evolution of a massless self-gravitating scalar field in spherical symmetry.

description: Vibration from demolition and construction activities poses a serious risk to museum objects. This case study presents preventive conservation and vibration monitoring strategies developed in response to a large-scale renovation project on the floor directly below the Egyptian Art galleries of the Metropolitan Museum of Art in order to safeguard this fragile, ancient art collection. The paper discusses the methods and procedures that were developed not only to protect the art but also to allow visitors continued access to as much of the collection as possible during the work period. In advance of the construction, pilot testing was performed to determine the levels of vibrations caused by different tools, as well as to gain a better understanding of vibration propagation within the museum and to specific objects through their mounts, pedestals, and display shelves. Vibration prone installations were modified with isolation and/or dampening approaches to mitigate vibration, or when possible, selected objects were deinstalled. A variety of mitigation solutions were shown to be effective through testing. During the demolition and construction phase, continuous wireless vibration monitoring was provided from within the galleries, and sometimes from sensors directly on objects or their shelves to provide near real-time alerts to museum staff and construction personnel. Alert levels were based on frequency independent velocity levels.

description: Collider data must be corrected for detector effects ("unfolded") to be compared with many theoretical calculations and measurements from other experiments. Unfolding is traditionally done for individual, binned observables without including all information relevant for characterizing the detector response. We introduce OmniFold, an unfolding method that iteratively reweights a simulated dataset, using machine learning to capitalize on all available information. Our approach is unbinned, works for arbitrarily high-dimensional data, and naturally incorporates information from the full phase space. We illustrate this technique on a realistic jet substructure example from the Large Hadron Collider and compare it to standard binned unfolding methods. This new paradigm enables the simultaneous measurement of all observables, including those not yet invented at the time of the analysis.

Dispersion approach to quark-binding effects in weak decays of heavy mesons
Creators: name: Melikhov, Dmitri
Publisher: name: arXiv
Year: 2001
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Dispersion approach based on the constituent quark picture and its applications to weak decays of heavy mesons are reviewed. Meson interaction amplitudes are represented within this approach as relativistic spectral integrals over the mass variables in terms of the meson wave functions and spectral densities of the corresponding Feynman diagrams. Various applications of this approach are discussed: Relativistic spectral representations for meson elastic and transition form factors at spacelike momentum transfers are constructed. Form factors at $q^2>0$ are obtained by the analytical continuation. As a result of this procedure, form factors are given in the full $q^2$ range of the weak decay in terms of the wave functions of the participating mesons. The 1/m_Q expansion of the obtained spectral representations for the form factors for the particular limits of the heavy-to-heavy and heavy-to-light transitions are analysed. Their full consistency with the constraints provided by long-distance QCD for these limits is demonstrated. Predictions for form factors for B, B(s), D, and D(s) decays to light mesons are given. The B\toγlνdecay and the weak annihilation in rare radiative decays are considered. Nonfactorizable corrections to the B^0-\bar B^0 mixing are calculated. Inclusive weak B-decays are analysed and the differential distributions are obtained in terms of the B-meson wave function.

description: We have developed a fast method to design perpendicular permanent magnets for simplifying stellarator coils based on existing codes. Coil complexity is one of the main challenges for stellarators. To date, only electromagnetic coils have been used to generate 3D fields for stellarators. Permanent magnets provide an alternative way to produce the desired magnetic field for optimized stellarators. In this paper, we revisit the concept of representing surface current using magnetic dipoles and carry out numerical validations. A surface magnetization is proven to be equivalent to the surface current that can be linearly solved by existing coil design codes. An incremental multi-layer method has been developed to obtain a practical solution that is attainable with present permanent magnets. With this method, we can reproduce a half-Tesla NCSX configuration using specially designed neodymium magnets together with simple planar coils. It shows that stellarator coils could be substantially simplified by adopting permanent magnets.
