description: This paper evaluates the results of a survey of Iowa pork producers, examining potential price discrimination by packers. Prices varied greatly across producers, and the examined variables explain just over half of the variation. Factors under the producer's control were the most significant variables and accounted for the vast majority of the explainable difference in price among producers. Packer buying systems also accounted for some difference in producer prices. Finally, variables related to operation size, while statistically significant, increased the explanatory values of the equation very little.

description: In this letter, we demonstrate high-performance lateral AlGaN/GaN Schottky barrier diodes (SBD) on Si substrate with a recessed-anode structure. The optimized rapid etch process provides results in improving etching quality with a 0.26-nm roughness of the anode recessed surface. By using the high work function metal Pt as the Schottky electrode, a low Von of 0.71 V is obtained with a high uniformity of 0.023 V for 40 devices. Supported by the flat anode recess surface and related field plate design, the SBD device with the anode-cathode spacing of 15 um show the Ron,sp of 1.53 mOhm.cm2 only, the breakdown voltage can reach 1592 V with a high power FOM (Figure-of-Merit) of 1656 MW/cm2. For the SBD device with the anode-cathode spacing of 30 um, the breakdown voltage can be as high as 2521 V and the power FOM is 1244 MW/cm2.

description: The core of the nebula surrounding Eta Carinae has been observed with the VLT Adaptive Optics system NACO and with the interferometer VLTI/MIDI to constrain spatially and spectrally the warm dusty environment and the central object. In particular, narrow-band images at 3.74 and 4.05 micron reveal the butterfly shaped dusty environment close to the central star with unprecedented spatial resolution. A void whose radius corresponds to the expected sublimation radius has been discovered around the central source. Fringes have been obtained in the Mid-IR which reveal a correlated flux of about 100Jy situated 0.3" south-east of the photocenter of the nebula at 8.7 micron, which corresponds with the location of the star as seen in other wavelengths. This correlated flux is partly attributed to the central object, and these observations provide an upper limit for the SED of the central source from 2.2 to 13.5 micron. Moreover, we have been able to spectrally disperse the signal from the nebula itself at PA=318 degree, i.e. in the direction of the bipolar nebula 310 degree) within the MIDI field of view of 3". A large amount of corundum (Al2O3) is discovered, peaking at 0.6-1.2" south-east from the star, whereas the dust content of the Weigelt blobs is dominated b silicates. We discuss the mechanisms of dust formation which are closely related to the geometry of this Butterfly nebulae.

description: The paper presents an econometric model of dynamic agricultural input demand functions that includes research based technical change and autoregressive disturbances and fits the model to data for a set of state aggregates pooled over 1950-82. The methodological approach is one of developing a theoretical foundation for a dynamic input demand system and accepting state aggregate behavior as approximated by nonlinear adjustment costs and long-term profit maximization. Although other studies have largely ignored autocorrelation in dynamic input demand systems, the results show shorter adjustment lags with autocorrelation than without autocorrelation. Dynamic input demand own-price elasticities for six input groups are inelastic, and the demand functions poses significant cross-price and research stock effects.

description: The rapid expansion of large-scale pork production has been accompanied by increasing concerns regarding potential detrimental consequences of environmental hazards on the health of producers. This study makes use of health indicators obtained from attendees at the World Pork Expo between 1991 and 1995 to evaluate the impact of pork production generally and of confinement production, specifically, on producer health. The analysis expands existing studies because the larger number of participants allows for detailed analysis, both nonfarmers and non-pork farmers are used as controls, both objective as well as self-reported health measures are considered, and personal characteristics such as height, weight, age, gender, smoking habits, and years of exposure to confinement operations and swine operations are controlled. The analysis shows that pork producers are more likely to report nagging respiratory symptoms (cough, sinus problems, sore throat) than are other farmers. Confinement operators have increased incidence of some symptoms relative to other pork producers. However, there was no evidence of permanent loss of pulmonary function associated with pork production or confinement operation. Farmers suffered from a greater incidence of hearing loss and loss of dominant hand strength relative to nonfarmers. Pork producers had even greater incidence of lost hand strength than other farmers but had no added incidence of hearing loss. On the plus side, farmers had lower blood pressure than did nonfarmers.

description: Pedestrians and cyclists are vulnerable road users. They are at greater risk for being killed in a crash than other road users. The percentage of fatal crashes that involve a pedestrian or cyclist is higher than the overall percentage of total trips taken by both modes. Because of this risk, finding ways to minimize problematic street environments is critical. Understanding traffic safety spatial patterns and identifying dangerous locations with significantly high crash risks for pedestrians and cyclists is essential in order to design possible countermeasures to improve road safety. This research develops two indicators for examining spatial correlation patterns between elements of the built environment (intersections) and crashes (pedestrian- or cyclist-involved). The global colocation quotient detects the overall connection in an area while the local colocation quotient identifies the locations of high-risk intersections. To illustrate our approach, we applied the methods to inspect the colocation patterns between pedestrian- or cyclist-vehicle crashes and intersections in Houston, Texas and we identified among many intersections the ones that significantly attract crashes. We also scrutinized those intersections, discussed possible attributes leading to high colocation of crashes and proposed corresponding countermeasures.

description: A new high time resolution observing mode for the Murchison Widefield Array (MWA) is described, enabling full polarimetric observations with up to 30.72 MHz of bandwidth and a time resolution of ~0.8 $μ$s. This mode makes use of a polyphase synthesis filter to "undo" the polyphase analysis filter stage of the standard MWA's Voltage Capture System (VCS) observing mode. Sources of potential error in the reconstruction of the high time resolution data are identified and quantified, with the S/N loss induced by the back-to-back system not exceeding -0.65 dB for typical noise-dominated samples. The system is further verified by observing three pulsars with known structure on microsecond timescales.

description: We discuss the origin of X-Ray Flashes (XRFs), a recently discovered class of Gamma-Ray Bursts (GRBs). Using a simplified model for internal shocks we check if XRFs can be intrinsically soft due to some specific values of the parameters describing the relativistic outflow emerging from the central engine. We generate a large number of synthetic events and find that XRFs are obtained when the contrast Gamma_max/Gamma_min of the Lorentz factor distribution is small while the average Lorentz factor Gamma is large. A few XRFs may be GRBs at large redshifts but we exclude this possibility for the bulk of the population. If outflows with a small contrast are commonly produced, even a large population of XRFs could be explained. If conversely the Lorentz factor distribution within the wind is broad, one should then rely on extrinsic causes, such as viewing angle effects or high redshift.

Cross-bispectra Constraints on Modified Gravity Theories from Nancy Grace Roman Space Telescope and Rubin Observatory Legacy Survey of Space and Time

description: One major goal of upcoming large-scale-structure surveys is to constrain dark energy and modified gravity theories. In particular, galaxy clustering and gravitational lensing convergence are probes sensitive to modifications of general relativity. While the standard analysis for these surveys typically includes power spectra or 2-point correlation functions, it is known that the bispectrum contains more information, and could offer improved constraints on parameters when combined with the power spectra. However, the use of bispectra has been limited so far to one single probe, e.g. the lensing convergence bispectrum or the galaxy bispectrum. In this paper, we extend the formalism to explore the power of cross-bispectra between different probes, and exploit their ability to break parameter degeneracies and improve constraints. We study this on a test case of lensing convergence and galaxy density auto- and cross-bispectra, for a particular sub-class of Horndeski theories parametrized by $c_M$ and $c_B$. Using the 2000 deg$^2$ notional survey of the Nancy Grace Roman Space Telescope with overlapping photometry from the Rubin Observatory Legacy Survey of Space and Time, we find that a joint power spectra and bispectra analysis with three redshift bins at $l_{\rm max} = 1000$ yields $σ_{c_M} = 1.0$ and $σ_{c_B} = 0.3$, both a factor of $\sim$1.2 better than the power spectra results; this would be further improved to $σ_{c_M} = 0.7$ and $σ_{c_B} = 0.2$ if $l_{\rm max} = 3000$ is taken. Furthermore, we find that using all possible cross-bispectra between the two probes in different tomographic bins improves upon auto-bispectra results by a factor of 1.3 in $σ_{c_M}$, 1.1 in $σ_{c_B}$ and 1.3 in $σ_{Ω_m}$. We expect that similar benefits of using cross-bispectra between probes could apply to other science cases and surveys.

description: We construct explicit BPS and non-BPS solutions of the Yang-Mills equations on the noncommutative space R^{2n}_θx S^2 which have manifest spherical symmetry. Using SU(2)-equivariant dimensional reduction techniques, we show that the solutions imply an equivalence between instantons on R^{2n}_θx S^2 and nonabelian vortices on R^{2n}_θ, which can be interpreted as a blowing-up of a chain of D0-branes on R^{2n}_θinto a chain of spherical D2-branes on R^{2n} x S^2. The low-energy dynamics of these configurations is described by a quiver gauge theory which can be formulated in terms of new geometrical objects generalizing superconnections. This formalism enables the explicit assignment of D0-brane charges in equivariant K-theory to the instanton solutions.

description: Compartmental ordinary differential equation (ODE) models are used extensively in mathematical biology. When transit between compartments occurs at a constant rate, the well-known linear chain trick can be used to show that the ODE model is equivalent to an Erlang distributed delay differential equation (DDE). Here, we demonstrate that compartmental models with non-linear transit rates and possibly delayed arguments are also equivalent to a scalar distributed delay differential equation. To illustrate the utility of these equivalences, we calculate the equilibria of the scalar DDE, and compute the characteristic function-- without calculating a determinant. We derive the equivalent scalar DDE for two examples of models in mathematical biology and use the DDE formulation to identify physiological processes that were otherwise hidden by the compartmental structure of the ODE model.

A PRELIMINARY ANALYSIS OF THE PROPOSED 1998 TAXPAYERS' RIGHTS AMENDMENTS TO THE IOWA CONSTITUTION AND FISCAL CONSEQUENCES ASSUMING IMPLEMENTATION FROM FY1984 TO PRESENT

description: This staff paper reviews the Senate (SSB2072) and House (HSB688) versions of a proposed 1998 Amendment to the Iowa Constitution and provides a preliminary analysis of the fiscal impacts on the state general fund receipts, general fund appropriations, and local property taxes assuming each proposal was implemented in FY 1984. While the year-to-year reductions in spending are relatively small, the cumulative fiscal impact of the SSB2072 would likely have resulted in (1) a FY1997 state general fund limit that allows 32 percent less spending than actual FY1997, (2) a $710 million reduction in the growth of state aid to local government, and (3) a 29.7 percent increase in property taxes, if property taxes were used to fully replace the reduction in growth of state aid to local governments. HSB688 excludes some measure of state aid applied to property tax relief from the TRA limit. However, the proposed Constitutional language for this exclusion appears to potentially contain ambiguous wording. One interpretation of HSB688 excludes only new state aid for property tax credits that "ensure" reduction in property taxes. Applying this definition to TRA implementation in FY1984 resulted in a FY1997 state general fund limit that allows 30.7 percent less spending than actual FY1997 and a $639 million reduction in the growth of state aid to local governments. In turn this would have required a 26.7 percent increase in property taxes to hold local government spending harmless from the reduction in growth of state aid to local governments. Alternatively, a second interpretation of HSB688 may provide a broader exclusion of state aid to local governments. If all new state aid to local government is excluded, the TRA would have resulted in a FY1997 state general fund limit that allows 15.7 percent less spending than actual FY1997. No reduction in the growth of state aid to local governments means no increase in local property taxes. However, the Constitutional tax and spending limitation effectively only covers half of the state general fund revenues.

description: Counting humans is an essential part of many people-centric applications. In this paper, we propose CrossCount: an accurate deep-learning-based human count estimator that uses a single WiFi link to estimate the human count in an area of interest. The main idea is to depend on the temporal link-blockage pattern as a discriminant feature that is more robust to wireless channel noise than the signal strength, hence delivering a ubiquitous and accurate human counting system. As part of its design, CrossCount addresses a number of deep learning challenges such as class imbalance and training data augmentation for enhancing the model generalizability. Implementation and evaluation of CrossCount in multiple testbeds show that it can achieve a human counting accuracy to within a maximum of 2 persons 100% of the time. This highlights the promise of CrossCount as a ubiquitous crowd estimator with non-labour-intensive data collection from off-the-shelf devices.

description: An agricultural household model provides the framework for modeling off-farm work participation and off-farm and on-farm work decisions of farm operators. The empirical results are obtained from fitting the econometric model to data from a large national survey. In the estimated structural off-farm work participation equation, the operator's off-farm wage offer has a strong positive effect and other household income has a negative effect on the probability of off-farm work. For farm operators who participate in off-farm work, the wage elasticity of their off-farm labor supply is positive but of their on-farm labor demand is zero. The income elasticity of off-farm work for those who participate in off-farm work and of on-farm work for those who specialize in farm work is negative. Implications are developed for the farm problem.

description: We use inelastic neutron scattering measurements to show that the energy gap in the magnetic excitations of URu$_2$Si$_2$, induced by the Hidden Order transition, is closed by Re substitution. The magnetic excitations remain ungapped in compositions where the specific heat anomaly associated with Hidden Order is no longer observed, which means that the entropy associated with Hidden Order is tied mostly to the magnetic gapping. Further, the onset of ferromagnetic order does not gap the excitations, reflecting the fact that Re substitution does not dramatically affect the Kondo lattice hybridization.

description: We present an inequality that gives a lower bound on the expectation value of certain two-body interaction potentials in a general state on Fock space in terms of the corresponding expectation value for thermal equilibrium states of non-interacting systems and the difference in the free energy. This bound can be viewed as a rigorous version of first order perturbation theory for many-body systems at positive temperature. As an application, we give a proof of the first two terms in a high density (and high temperature) expansion of the free energy of jellium with Coulomb interactions, both in the fermionic and bosonic case. For bosons, our method works above the transition temperature (for the non-interacting gas) for Bose-Einstein condensation.

description: We study evolution of a hierarchical four-body (2+2) system composed by a pair of mass-transferring white dwarf binaries. Applying a simplified model around the synchronous state of two inner orbital periods, we newly find that the four body system could settle down to a limit cycle with a small period gap. The period gap generates an amplitude variation of emitted gravitational waves, as a beat effect. Depending on model parameters, the beat period could be 1-10 yr and a large amplitude variation might be observed by space gravitational-wave detectors.

description: We present numerical simulations of galaxy clusters which include interaction processes between the galaxies and the intra-cluster gas. The considered interaction processes are galactic winds and ram-pressure stripping, which both transfer metal-enriched interstellar medium into the intra-cluster gas and hence increase its metallicity. We investigate the efficiency and time evolution of the interaction processes by simulated metallicity maps, which are directly comparable to those obtained from X-ray observations. We find that ram-pressure stripping is more efficient than quiet (i.e. non-starburst driven) galactic winds in the redshift interval between 1 and 0. The expelled metals are not mixed immediately with the intra-cluster gas, but inhomogeneities are visible in the metallicity maps. Even stripes of higher metallicity that a single galaxy has left behind can be seen. The spatial distribution of the metals transported by ram-pressure stripping and by galactic winds are very different for massive clusters: the former process yields a centrally concentrated metal distribution while the latter results in an extended metal distribution.

description: Following the basic principles stated by Painlevé, we first revisit the process of selecting the admissible time-independent Hamiltonians $H=(p_1^2+p_2^2)/2+V(q_1,q_2)$ whose some integer power $q_j^{n_j}(t)$ of the general solution is a singlevalued function of the complex time $t$. In addition to the well known rational potentials $V$ of Hénon-Heiles, this selects possible cases with a trigonometric dependence of $V$ on $q_j$. Then, by establishing the relevant confluences, we restrict the question of the explicit integration of the seven (three ``cubic'' plus four ``quartic'') rational Hénon-Heiles cases to the quartic cases. Finally, we perform the explicit integration of the quartic cases, thus proving that the seven rational cases have a meromorphic general solution explicitly given by a genus two hyperelliptic function.

description: We used extensions of traditional ARCH and GARCH models to examine the difference in the behavior of the first two moments of the price distribution during collusion and the absence of it using prices from two recently discovered conspiracies, citric acid and lysine. According to our results, the citric acid conspiracy increased prices by 9 cents per pound relative to pre-cartel and post-cartel periods. The lysine conspiracy managed to raise prices by 25 cents per pound. In addition, the variance of prices during the lysine conspiracy was lower than the variance of prices during pre-cartel and post-cartel periods as we expected. In contrast, the variance of prices during the citric acid conspiracy was higher relative to more competitive periods.

description: Recent optical and IR studies have revealed that the heavily-reddened starburst cluster Westerlund 1 (Wd 1) contains at least 22 Wolf-Rayet (WR) stars, comprising the richest WR population of any galactic cluster. We present results of a senstive Chandra X-ray observation of Wd 1 which detected 12 of the 22 known WR stars and the mysterious emission line star W9. The fraction of detected WN stars is nearly identical to that of WC stars. The WN stars WR-A and WR-B as well as W9 are exceptionally luminous in X-rays and have similar hard heavily-absorbed spectra with strong Si XIII and S XV emission lines. The luminous high-temperature X-ray emission of these three stars is characteristic of colliding wind binary systems but their binary status remains to be determined. Spectral fits of the X-ray bright sources WR-A and W9 with isothermal plane-parallel shock models require high absorption column densities log N$_{H}$ = 22.56 (cm$^{-2}$) and yield characteristic shock temperatures kT_shock ~ 3 keV (T ~ 35 MK).

Ancestral Demon of a Grieving Bride (Sy Hoahwah)
Creators: name: Warren, Hannah V
Publisher: name: Transmotion
Year: 2021

description: In this place-oriented collection, Hoahwah forces the reader to reconcile the blurring of assumed borders between natural and unnatural, life and death, and more as he defines the hybrid body/bodies of the speaker against and within liminal landscapes: “I sat here long enough / to become an altar / where the abandoned monsters come to pray” (24). Pulling from epic and Gothic traditions, Hoahwah’s new collection of poetry allows us brief visions of an impossibly shifting narrator—one we must trust fully as we follow the speaker to the outskirts of town, down a logging trail, and into Hell, itself.

description: Staggered and linear multi-particle trains constitute characteristic structures in inertial microfluidics. Using lattice-Boltzmann simulations, we investigate their properties and stability, when flowing through microfluidic channels. We confirm the stability of cross-streamline pairs by showing how they contract or expand to their equilibrium axial distance. In contrast, same-streamline pairs quickly expand to a characteristic separation but even at long times slowly drift apart. We reproduce the distribution of particle distances with its characteristic peak as measured in experiments. Staggered multi-particle trains initialized with an axial particle spacing larger than the equilibrium distance contract non-uniformly due to collective drag reduction. Linear particle trains, similar to pairs, rapidly expand toward a value about twice the equilibrium distance of staggered trains and then very slowly drift apart non-uniformly. Again, we reproduce the statistics of particle distances and the characteristic peak observed in experiments. Finally, we thoroughly analyze the damped displacement pulse traveling as a microfluidic phonon through a staggered train and show how a defect strongly damps its propagation.

description: This research explores the welfare consequences of substituting carbon taxes for conventional distortionary taxes in a small open economy, using Pennsylvania as case study. A computable general equilibrium (CGE) model is developed for Pennsylvania to simulate possible outcomes when carbon taxes are substituted for conventional taxes. Consumer welfare impacts from environmental tax reform are conventionally decomposed into three effects: the Pigouvian effect, the tax revenue recycling effect, and the tax interaction effects. The Pigouvian effect is a welfare gain from reducing environmental externalities. The tax revenue effect is a welfare gain from reduced distortion in factor and commodity markets that results from the substitution of the environmental tax for conventional distortionary taxes. The tax interaction effect is a welfare loss due to increased distortion of factor and commodity markets induced by environmental taxes, given that distortionary taxes are not eliminated. The 'Double dividend' hypothesis argues that the sum of welfare gains is larger than the welfare loss. Most research on this debate has been done using closed-economy models. Small open economies, however, have different aspects from closed economies. These include endogenous factor mobility and trade. Factor mobility triggered by changes in real wages and environmental quality can affect distortions of regional labor market, leading to the different welfare outcomes.. When the carbon tax is imposed in open economies, inter-regional trade sectors are more responsive than foreign trades, since the elasticity of substitution for inter-regional trades is higher than that for the foreign trades. This different inter-regional trading effect leads to different welfare outcomes.

description: Conservation technology adoption behavior is frequently analyzed at the smallest unit of production to capture important heterogeneity among adopters. Conclusions about firm-level decisions are drawn from these microunit outcomes. However, there may be significant intrafirm interactions that create a dependence among the microunits. This paper tests and quantifies these effects. Using a unique dataset of agricultural water use in California, this paper finds significant differences in water price elasticities of conservation technology adoption between the standard model and models that accounts for the intrafirm interactions.
The MPI implementation on NetVM

description: Advances in network technology now allow an application to reliably transfer data to a remote node without remote CPU intervention. It removes the communication overhead of traditional operating systems by allowing the sender to directly write to the memory of a remote node. However, translating remote memory semantics into standard stream-oriented interfaces like MPI is challenging. In this thesis we demonstrate the possibility and efficiency of using the remote memory technology as the underlying communication system in our implementation of MPI. Our performance results show significantly improvement on both microbenchmarks and real-world applications compared to LAM over Myrinet. The remote memory model is shown to be powerful in implementing MPI semantics.

description: A simulation model is developed to quantify the effects of information and trading ratios on the performance of a water quality market. An application of this model to a northeast Kansas watershed suggests that performance is improved by information provision and a 1:1 trading ratio between point and nonpoint loadings.

description: We investigate the Peierls transition in the one-dimensional Peierls-Hubbard model at half filling in the adiabatic approximation for the lattice. Depending on the value of the electron-lattice coupling constant g the equilibrium dimerization can be either enhanced or suppressed by the Hubbard interaction U. Applying second order perturbation theory we determine the critical value g_c = 0.689348 below which the Hubbard interaction enhances the dimerization.

description: We investigate a hedonic model for veterinarian income using survey data from the American Veterinarian Medical Association. Diagnostic testing indicates the presence of spatial autoregression in the hedonic income model, which is accounted for by incorporating a spatial component into the regression model. The results provide unique empirical findings about determinants of veterinarian income and spatial patterns, as well as insight useful for governments and academic institutions planning programs and the veterinarian industry.
Mixed quantum-classical approach to model non-adiabatic electron-nuclear dynamics: Detailed balance and improved surface hopping method

description: We develop a density matrix formalism to describe coupled electron-nuclear dynamics. To this end we introduce an effective Hamiltonian formalism that describes electronic transitions and small (quantum) nuclear fluctuations along a classical trajectory of the nuclei. Using this Hamiltonian we derive equations of motion for the electronic occupation numbers and for the nuclear coordinates and momenta. We show that in the limit when the number of nuclear degrees of freedom coupled to a given electronic transition is sufficiently high (i.e., the strong decoherence limit), the equations of motion for the electronic occupation numbers become Markovian. Furthermore the transition rates in these (rate) equations are asymmetric with respect to the lower-to-higher energy transitions and vice versa. In thermal equilibrium such asymmetry corresponds to the detailed balance condition. We also study the equations for the electronic occupations in non-Markovian regime and develop a surface hopping algorithm based on our formalism. To treat the decoherence effects we introduce additional "virtual" nuclear wavepackets whose interference with the "real" (physical) wavepackets leads to the reduction in coupling between the electronic states (i.e., decoherence) as well as to the phase shifts that improve the accuracy of the numerical approach. Remarkably, the same phase shifts lead to the detailed balance condition in the strong decoherence limit.
