description: Biomimicry, the science of learning from nature to solve human challenges, offers a sustainable pathway for architectural innovation. This study explores how biomimicry architecture can be applied in Nigeria’s built environment, providing nature-based solutions for climate-responsive and energy-efficient designs.

Using a qualitative research approach, the study incorporates case studies and expert interviews to assess the potential of biomimicry in Nigeria. Interview data was analyzed using Dedoose software, highlighting key themes such as energy efficiency, environmental sustainability, and occupant well-being. The findings reveal that while professionals recognize the benefits of biomimetic design, challenges such as high costs, socio-cultural perceptions, and limited awareness hinder its widespread adoption.

To bridge these gaps, the research recommends targeted awareness programs, policy improvements, and curriculum integration in architectural education. This study contributes to the growing discourse on sustainable and biomimetic architecture, serving as a foundation for future research and policy development in Nigeria.

description: The Methanol MultiBeam survey (MMB) provides the most complete sample of Galactic massive young stellar objects (MYSOs) hosting 6.7GHz class II methanol masers. We characterise the properties of these maser sources using dust emission detected by the Herschel Infrared Galactic Plane Survey (Hi-GAL) to assess their evolutionary state. Associating 731 (73%) of MMB sources with compact emission at four Hi-GAL wavelengths, we derive clump properties and define the requirements of a MYSO to host a 6.7GHz maser. The median far-infrared (FIR) mass and luminosity are 630M$_{\odot}$ and 2500L$_{\odot}$ for sources on the near side of Galactic centre and 3200M$_{\odot}$ and 10000L$_{\odot}$ for more distant sources. The median luminosity-to-mass ratio is similar for both at $\sim$4.2L$_{\odot}/$M$_{\odot}$. We identify an apparent minimum 70$μ$m luminosity required to sustain a methanol maser of a given luminosity (with $L_{70} \propto L_{6.7}^{0.6}$). The maser host clumps have higher mass and higher FIR luminosities than the general Galactic population of protostellar MYSOs. Using principal component analysis, we find 896 protostellar clumps satisfy the requirements to host a methanol maser but lack a detection in the MMB. Finding a 70$μ$m flux density deficiency in these objects, we favour the scenario in which these objects are evolved beyond the age where a luminous 6.7GHz maser can be sustained. Finally, segregation by association with secondary maser species identifies evolutionary differences within the population of 6.7GHz sources.

title: The Effects of Religious Coping and Drinking to Cope on the Relationship Between Depressive Symptoms and Alcohol-Related Problems

description: The present research examined the moderating effect of religious coping (positive or negative) on the relationship between depressive symptoms and alcohol-related problems. Furthermore, the current study examined the moderating effects of positive and negative religious coping in the context of the confirmed mediation of drinking to cope on depression and alcohol related problems (i.e., moderated-mediation). The study consisted of 294 religious undergraduate student drinkers from a large southeastern university. The majority of participants identified themselves as Christian (n = 257, 87.4%), were female (n = 218, 74.1%), and reported a mean age of21.85 (SD= 5.57) years. Participants completed measures of depressive symptoms, alcohol use, alcohol-related problems, drinking to cope, and religious coping. The present study found partial support for the Maladaptive Coping Hypothesis among religious college student drinkers. In particular, negative religious coping moderated the relationship between depressive symptoms and alcohol-related problems. In addition, negative religious coping affects another maladaptive coping strategy (i.e., drinking to cope) by moderating the meditating effects of drinking to cope on the relationship between depressive symptoms and alcohol-related problems. However, positive religious coping was unrelated to all major study variables. The implication of this study may be important for future interventions to tap into improving coping strategies for religious individuals who report high levels of depressive symptoms.

description: We present an XMM-Newton catalogue of BL Lac X-ray, optical, and UV properties based on cross-correlation with the 1151 BL Lacs listed in the fifth edition of the Roma-BZCAT. We searched for the X-ray counterparts to these objects in the field of view of all pointed observations in the XMM-Newton archive over nearly 20 years of mission. The cross-correlation yields a total of 310 XMM-Newton fields which correspond to 103 different BL Lacs. We homogeneously analysed data from the three EPIC cameras (X-ray) and OM(optical/UV) using the XMM-Newton SAS software, and produced images, light curves, and spectral products for BL Lacs detected in any of the three EPIC cameras. We tested two different phenomenological models, log parabola and power law, with different variations of the absorbing column density and extracted their parameters. We derived time-variability information from the light curves following well-established statistical methods and quantified variability through statistical indicators. OM magnitudes and fluxes were computed wherever possible. We see that the log parabola model is preferred over the power law model for sources showing higher fluxes, which might indicate that curvature is intrinsic to BL Lacs and is only seen when the flux is high. We present the results of our analysis as a catalogue of X-ray spectral properties of the sample in the 0.2-10 keV energy band as well as in the optical/UV band. We complete the catalogue with multi-wavelength information at radio and gamma-ray energies.

description: Using inelastic x-ray scattering beyond the dipole limit and hard x-ray photoelectron spectroscopy we establish the dual nature of the U $5f$ electrons in UM$_2$Si$_2$ (M = Pd, Ni, Ru, Fe), regardless of their degree of delocalization. We have observed that the compounds have in common a local atomic-like state that is well described by the U $5f^2$ configuration with the $Γ_1^{(1)}$ and $Γ_2$ quasi-doublet symmetry. The amount of the U 5$f^3$ configuration, however, varies considerably across the UM$_2$Si$_2$ series, indicating an increase of U5$f$ itineracy in going from M=Pd to Ni to Ru, and to the Fe compound. The identified electronic states explain the formation of the very large ordered magnetic moments in UPd$_2$Si$_2$ and UNi$_2$Si$_2$, the availability of orbital degrees of freedom needed for the hidden order in URu$_2$Si$_2$ to occur, as well as the appearance of Pauli paramagnetism in UFe$_2$Si$_2$. A unified and systematic picture of the U$M_2$Si$_2$ compounds may now be drawn, thereby providing suggestions for new experiments to induce hidden order and/or superconductivity in U compounds with the tetragonal body-centered ThCr$_2$Si$_2$ structure.

An error reduction by an order of magnitude can be obtained with respect to the Eichten-Hill action, for time separations beyond 1.3 fm, keeping discretization errors small. The best actions lead to a big improvement on the precision of the quark mass Mb and F_Bs in the static approximation.

description: Gravitational-wave astronomy provides a unique new way to study the expansion history of the Universe. In this work, we investigate the impact future gravitational-wave observatories will have on cosmology. Third-generation observatories like the Einstein Telescope and Cosmic Explorer will be sensitive to essentially all of the binary black hole coalescence events in the Universe. Recent work by \cite{farr2019future} points out that features in the stellar-mass black hole population break the mass-redshift degeneracy, facilitating precise determination of the Hubble parameter without electromagnetic counterparts or host galaxy catalogues. Using a hierarchical Bayesian inference model, we show that with one year of observations by the Einstein Telescope, the Hubble constant will be measured to $\lesssim 1\%$. We also show that this method can be used to perform Bayesian model selection between cosmological models. As an illustrative example, we find that a decisive statement can be made comparing the $Λ$CDM and RHCT cosmological models using two weeks of data from the Einstein Telescope.

Spatial Locality of Galaxy Correlation Function in Phase Space: Samples from the 2MASS Extended Source Catalog

description: We analyze the statistical properties and dynamical implications of galaxy distributions in phase space for samples selected from the 2MASS Extended Source Catalog. The galaxy distribution is decomposed into modes $δ({\bf k, x})$ which describe the number density perturbations of galaxies in phase space cell given by scale band $\bf k$ to ${\bf k}+Δ{\bf k}$ and spatial range $\bf x$ to ${\bf x}+Δ{\bf x}$. In the nonlinear regime, $δ({\bf k, x})$ is highly non-Gaussian. We find, however, that the correlations between $δ({\bf k, x})$ and $δ({\bf k', x'})$ are always very weak if the spatial ranges (${\bf x}$, ${\bf x}+Δ{\bf x}$) and (${\bf x'}$, ${\bf x'}+Δ{\bf x'}$) don't overlap. This feature is due to the fact that the spatial locality of the initial perturbations is memorized during hierarchical clustering. The highly spatial locality of the 2MASS galaxy correlations is a strong evidence for the initial perturbations of the cosmic mass field being spatially localized, and therefore, consistent with a Gaussian initial perturbations on scales as small as about 0.1 h$^{-1}$ Mpc. Moreover, the 2MASS galaxy spatial locality indicates that the relationship between density perturbations of galaxies and the underlying dark matter should be localized in phase space. That is, for a structure consisting of perturbations on scales from $k$ to $ k+Δ{k}$, the nonlocal range in the relation between galaxies and dark matter should {\it not} be larger than $|{Δ{\bf x}}|=2π/|Δ{\bf k}|$. The stochasticity and nonlocality of the bias relation between galaxies and dark matter fields should be no more than the allowed range given by the uncertainty relation $|{Δ{\bf x}|| Δ{\bf k}}|=2π$.

description: We study three types of star products in SFT: the ghosts, the twisted ghosts and the matter. We find that their Neumann coefficients are related to each other in a compact way which includes the Gross-Jevicki relation between matter and ghost sector: we explicitly show that the same relation, with a minus sign, holds for the twisted and nontwisted ghost (which are different but define the same solution). In agreement with this, we prove that matter and twisted ghost coefficients just differ by a minus sign. As a consistency check, we also compute the spectrum of the twisted ghost vertices from conformal field theory and, using equality of twisted and reduced slivers, we derive the spectrum of the non twisted ghost star.

description: Objectives: This study evaluated inpatient admission status, hospitalization length of stay (LOS), hospital costs, and readmissions of patients who were diagnosed with venous thromboembolism (VTE) and treated with apixaban or warfarin in the emergency department (ED). Methods: Patients (≥18 years) with an ED visit with a primary discharge diagnosis code of VTE were identified from the Premier Hospital database (8/1/2014-5/31/2018). Patients who received apixaban or warfarin during the ED visit were selected and grouped into two treatment cohorts. Outcomes of ED disposition (discharged or admitted to the inpatient setting), hospital LOS, hospital cost of index event, and rate of 1-month readmissions were compared for the study cohorts. Results: Of the overall study population, 30.5% (n = 12,174; mean age: 59.7 years) received apixaban and 69.5% (n = 27,767; mean age: 59.3 years) received warfarin for VTE in the ED. After adjusting for patient and hospital characteristics, the regression analysis showed that apixaban was associated with a significantly lower likelihood of admission to the inpatient setting vs. warfarin (Odds Ratio [OR]: 0.12, 95% Confidence Interval [CI]: 0.12 to 0.13; p Conclusions: In the real-world setting, VTE patients with an ED visit who were treated with apixaban vs. warfarin had a lower likelihood of being admitted to the inpatient setting, which was reflected in shorter average LOS and lower average index event cost. Additionally, the risk of 1-month readmission was also lower for patients treated with apixaban vs. warfarin.

These templates allow systematic collection of data on occupational and environmental release and exposure of nanoforms (NFs). There is a lack of release and exposure data and that available has not been collected in a harmonised way making difficult the comparison of scenarios to evaluate the influence of different approaches to reduce release and exposure. The templates include all data required to interpret a scenario so it is possible to read across from a “source scenario” to a scenario for which measurement data is not available base on the type of NF, matrix, specific activity, exposure controls. The templates are also available from the EU funded eNanoMapper database platform. The templates are free to use under the licence agreement “Creative Commons - Share alike”. If you intend to use these templates, as such or modifying them, please acknowledge the primary source mentioning "GRACIOUS Release and Exposure Templates".

description: This paper concentrates on building a multi-antenna FPGA based Channel Sounder with single transmitter and multiple receivers to realize wireless propagation characteristics of an indoor environment. A DSSS signal (spread with a real maximum length PN sequence) is transmitted, which is correlated with the same PN sequence at each receiver to obtain the power delay profile . Multiple power delay profiles are averaged and the result is then sent to host. To utilize high bandwidth, the computationally expensive tasks related to generation and parallel correlation of PN sequences are moved to the FPGA present in each USRP (Universal Software Radio Peripheral). Channel sounder blocks were built using Vivado HLS and integrated with RFNoC (RF Network on Chip) framework, which were then used on USRP X310 devices.

description: Wide-field gamma-ray telescopes typically have highly variable event-by-event resolution which leads to a number of unique and challenging analysis requirements -- particularly when conducting transient searches over multiple time scales. By generalizing the ideas of the Gaussian weighting analysis to point-spread functions of arbitrary shape and the regime of Poisson statistics, an efficient analysis which uses the event-by-event resolution is developed with a sensitivity similar to that of a well-implemented maximum likelihood analysis. In this development, the effect of a number of different approximations on the sensitivity and speed of the final analysis can be easily determined and tuned to the particular application. The analysis method is particularly well suited to transient detection in wide field-of-view gamma-ray observatories, and is currently used for the 40 s -- 3 hour transient search in the Milagro observatory.

A deeply optimized software allows one to efficiently construct such operators for the first non-degenerate 2-loop cases. The most efficient approach is found to be via the so-called partial operators that are much simpler than the complete ones, and that affect the power of only one of the polynomials in the product.

Demand and Price Analysis

description: The use of price indices as deflators in demand equations is considered and clarified. Deflating prices and income by the CPI imposes a type of homogeneity restriction, but invalidates the interpretation of coefficients of a double-log model as uncompensated elasticities. However, deflating income by Stone's geometric price index-not the Consumer Price Index-means that real income really is held constant. This permits interpreting price coefficients in a double-log demand equation as compensated elasticities, provided the homogeneity restriction is imposed properly. While this result has been known since Stone (1954), it does not appear to be widely recognized in the literature on applied demand analysis. The compensated version of the double-log model has the same form as a share equation from the widely used linear approximate version of the Almost Ideal demand system, facilitating the construction of a test for choosing between these two alternative models. In an illustrative example using Theil's data for U.S. meat consumption, both the double-log and share specifications are rejected.

description: In this work, we present an approach for monocular hand-eye calibration from per-sensor ego-motion based on dual quaternions. Due to non-metrically scaled translations of monocular odometry, a scaling factor has to be estimated in addition to the rotation and translation calibration. For this, we derive a quadratically constrained quadratic program that allows a combined estimation of all extrinsic calibration parameters. Using dual quaternions leads to low run-times due to their compact representation. Our problem formulation further allows to estimate multiple scalings simultaneously for different sequences of the same sensor setup. Based on our problem formulation, we derive both, a fast local and a globally optimal solving approach. Finally, our algorithms are evaluated and compared to state-of-the-art approaches on simulated and real-world data, e.g., the EuRoC MAV dataset.

description: The government intends to rely on an insurance-based solution to yield risk, therefore, it is important to identify which characteristics most effect a grower's decision regarding whether or not to use crop insurance. This case study uses California cross sectional survey data to directly compare the relative effects of three types of characteristics which are expected to influence insurance preferences. In general, results from the model estimated indicate that preferences for crop insurance are a function of both the commodities produced and the risk environment faced by individual growers.

description: Astrophysical observations provide a unique opportunity to test possible signatures of Lorentz Invariance Violation (LIV), due to the high energies and long distances involved. In quantum theory of gravity, one may expect the modification of the dispersion relation between energy and momentum for photons, which can be probed with the time-lag (the arrival time delay between light curves in different energy bands) of Gamma-ray bursts (GRBs). In this paper, by using the detailed time-delay measurements of GRB 160625B at different energy bands, as well as 23 time-delay GRBs covering the redshifts range of $z=0.168-2.5$ (which were measured at different energy channels from the light curves), we propose an improved model-independent method (based on the newly-compiled sample of $H(z)$ measurements) to probe the energy-dependent velocity due to the modified dispersion relation for photons. In the framework of a more complex and reasonable theoretical expression to describe the time delays, our results imply that the intrinsic time lags can be better described with more GRBs time delay data. More importantly, through direct fitting of the time-delay measurements of a sample of GRBs, our limit on the LIV energy scale is comparable to that with unknown constant for the intrinsic time lag, much lower than the Planck energy scale in both linear LIV and quadratic LIV cases.

description: By exploiting the diffeomorphism invariance we relate the finite size effects of massless theories to their Weyl anomaly. We show that the universal contributions to the finite size effects are determined by certain coefficient functions in the heat kernel expansion of the related wave operators. For massless scalars confined in a $4$-dimensional curved spacetime with boundary the relevant coefficients are given -- confirming the results of Moss and Dowker and also of Branson and Gilkey. We apply the general results to theories on bounded regions in two- and four-dimensional flat space-times and determine the change of the effective action under arbitrary conformal deformations of the regions.

description: The rheology of coextruded layered films of polystyrene/poly(methyl methacrylate) (PS/PMMA) has been studied with small and large amplitude oscillations at a temperature above their glass transition. While the complex viscosity remains constant over the experimental time window for the micron-sized layered films, a decrease has been observed for the nanolayered films. The rheological behavior has then been correlated to the morphological evolution of the multilayer films: while the nanolayers dewet. Layer breakup followed by retraction and coalescence leading to a lamellar-like blend morphology succeeded by a nodular-like morphology has been evidenced in the nanolayer films, for all compositions and conditions tested. The analysis of the microscopic images of the film cross-sections also provided the droplet size distribution. The nodular morphology is achieved more rapidly when the initial layers are the thinnest at low strains, while at high strains the formation of these droplets is prevented.

description: The interplay of prospective experimental information from both the Large Hadron Collider (LHC) and the Linear Collider (LC) in the investigation of the MSSM Higgs sector is analyzed in the SPS~1a and SPS 1b benchmark scenarios. Combining LHC information on the heavy Higgs states of the MSSM with precise measurements of the mass and branching ratios of the lightest CP-even Higgs boson at the LC provides a sensitive consistency test of the MSSM. This allows to set bounds on the trilinear coupling A_t. In a scenario where LHC and LC only detect one light Higgs boson, the prospects for an indirect determination of M_A are investigated. In particular, the impact of the experimental errors of the other SUSY parameters is analyzed in detail. We find that a precision of about 20% (30%) can be achieved for M_A = 600 (800) GeV.

description: In this review, we summarize recent findings that show how standard 4-d Einstein gravity coupled to a conformal field theory can become massive in Anti de Sitter Space. Key ingredients in this phenomenon are non-standard ``transparent'' boundary condition given to the CFT fields and the fact that AdS space is not globally hyperbolic, due to the presence of a time-like boundary.

description: Here we report a new quasi-one-dimensional $S$ = 1 chain compound NiTe$_{2}$O$_{5}$. From the comprehensive study of the structure and magnetic properties on high quality single crystalline NiTe$_{2}$O$_{5}$, it's revealed that NiTe$_{2}$O$_{5}$ undergoes a transition into an intriguing long-range antiferromagnetic order at $T_{\rm N}=30.5 {\rm K}$, in which longitudinal magnetic moments along the chain direction are ferromagnetically ordered, while their transverse components have an alternating ferromagnetic-antiferromagnetic coupling. Even though the temperature dependence of magnetic susceptibility represents an archetypal anisotropic antiferromagnetic order, we found that critical behavior of unconventional nature with $α'\sim0.25$ and $β\sim0.18$ is accompanied by the temperature evolution of the antiferromagnetic order parameter.

description: We examine whether there are spatial relationships in U.S. production agriculture's profitability across regions and over time. We test the traditional view that factor markets (approximately) adjust to equalize agriculture's net returns over space and time using county-level data from the USDA's Census of Agriculture, 1992 and 1997. We estimate Gini coefficients and calculate the Theil Entropy Measure (TMI) to examine changes in the concentration of returns over space and time, and to decompose the variation in inequality in returns into two components: the percent of total variation in returns due to within-region inequality, and the percent of variation in returns due to between-region variation in returns. Although factor markets (approximately) adjust to equalize net returns over space and time, there is still considerable variability in returns within regions and within states. Use of county-level (Census of Agriculture) and farm-level data (ARMS Survey) to help highlight these differences. In general, farm-level Gini coefficients have remained fairly constant but show a mild increase in concentration since the 1996 FAIR Act. The TMI analysis reveals that in 1997 about 54 percent of the variation in total returns (net cash returns) was due to within-region variation, and about 46 percent was due to (average) between region variation (compared to 53 and 47 percent in 1992). Total U.S. inequality of net cash returns increased from 0.14 in 1992 to 0.21 in 1997.

description: We study thermodynamics of dynamical traversable wormholes. These wormholes are investigated in the background of different cosmological models, with and without the cosmological constant, and which include the power-law and exponential cosmologies also. We work out the generalized surface gravity for wormholes of different shapes. The surface gravity is evaluated at the trapping horizon and the unified first law of thermodynamics is set up. The thermodynamic stability of these wormholes has also been investigated. Some cases of asymptotically flat, de Sitter and anti-de Sitter wormholes have been considered as well. Our results generalize those that exist for static Morris-Thorne wormholes.

description: This study uses portfolio theory to evaluate the effects of off-farm income on the labor allocation and production decisions of American farmers. It finds that hedging with off-farm income makes markets more risky, although the effects decrease for larger farm sizes. Farmers respond to increases in off-farm income opportunities by producing more-risky crops, but they produce using a smaller percentage of available household labor. Empirically, off-farm income is significant in raising the wealth of only mid-sized farms. It appears that hedging with off-farm income effectively reduces farm households' risk exposure level, but it creates a need for new agricultural policies.

description: Beach recreation values are often needed by policy-makers and resource managers to efficiently manage coastal resources, especially in popular coastal areas like Southern California. This paper presents welfare values derived from random utility maximization-based recreation demand models that explain an individual's decisions about whether or not to visit a beach and which beach to visit. The models are consistent with underlying time- and money-constrained choices and utilize labor market decisions to reveal each individual's opportunity cost of recreation time. The value of a beach day at San Diego County beaches is estimated to be between $21 and $26.
RETURN ON EQUITY: THE ROLE OF ASSETS AND LIABILITY MANAGEMENT IN QUOTED COMMERCIAL BANKS IN NIGERIA

description: This study examined the relationship between assets and liability management and return on equity of quoted commercial banks from 2013-2023. Cross sectional data were sourced from annual reports of the quoted commercial banks. Return on equity was proxy for dependent variable while liquidity management, assets management, liability management and credit management were proxies for independent variables. Panel data regression was used as data analysis methods. Findings of the study revealed that the fixed effect model shows that the independent variable explains 89 percent variation on the return on equity. The F-statistics and the F-Probability validates that the model is significant. The beta coefficient showed that all the independent variables have positive effect on return on equity except liquidity management. From the findings, the study conclude that assets and liability management have significant relationship with return on equity of the quoted commercial banks in Nigeria. The study recommends that regular review of asset liability management policies and tools should be done by the bank’s board of directors to ensure that they are in line with market developments in Asset liability management process. Banks management should comply with cash reserve requirements, which help them to avoid insolvency and maintain sustainability profitability.

description: We estimate the cosmic production rate of helium relative to metals ($ΔY/ΔZ$) using K dwarf stars in the Hipparcos catalog with accurate spectroscopic metallicities. The best fitting value is $ΔY/ΔZ=2.1 \pm 0.4$ at the 68% confidence level. Our derived value agrees with determinations from HII regions and with theoretical predictions from stellar yields with standard assumptions for the initial mass function. The amount of helium in stars determines how long they live and therefore how fast they will enrich the insterstellar medium with fresh material.

Dependence of Lightcurves on Phase Angle and Asteroid Shape

description: We investigate the phase angle dependence of asteroid lightcurves using numerical scattering models applied to simple body shapes. For simplicity, the Kaasalainen scattering parameters are obtained from the corresponding Hapke scattering laws for C-type, S-type, and V-type asteroids. The spectral types differ substantially in the role of multiple scattering (which is largely a function of their geometric albedos) but we find that the differences on the light curve vs.~phase relations are modest. By using a Kaasalainen scattering law, the amplitudes and axis ratios with respect to different phase angles from $0^\circ$ to $140^\circ$ are plotted for these types asteroids based on a biaxial ellipsoid shape model. Additionally, we examine the relationship between amplitude and axis ratio for a contact binary represented by identical biaxial ellipsoids, including the effects of shadowing of one component by the other. We compare the models with published high phase angle observations, and with interstellar object 1I/`Oumuamua ($Δm = 2.5$ magnitude at phase angle $α= 23^\circ$), finding axis ratio $5.2:1$ if represented as a single ellipsoid and $3.5:1$ for each component if represented as a nose-to-nose contact binary. While a detailed fit is not attempted, the comparison shows that the single ellipsoid model is better.

description: This study assesses the possible relationship between industry structure and the expanding use of production contracting. We propose that there are unique structural constraints in each commodity market that determine the potential for production contracting. We test hypotheses on (1) the expected positive relationship between concentration in an agribusiness industry and the extent of production contracting for the relevant commodity, (2) the expected negative relationship between the share of a commodity produced on contract and the number of products made from that commodity, and (3) the expected negative relationship between the number of commercial uses applicable to a commodity and the concentration of buyers of that commodity. We present empirical data from a small cross section of commodities that are consistent with these hypotheses. Also, we explore the significant differences between agricultural producers who enter into production contracts and those who remain independent. Based on our results, we draw preliminary inferences on the future of production contracting in American agriculture-its potential for expansion as well as its fundamental limitations

description: The quasi-neutral hybrid particle-in-cell algorithm with kinetic ions and fluid electrons is a popular model to study multi-scale problems in laboratory, space, and astrophysical plasmas. Here, it is shown that the treatment of ions as finite-size particles and electrons as a grid-based fluid can cause significant numerical wave dispersion errors in the magnetohydrodynamic limit ($kd_i \ll 1$, where $d_i$ is the ion skin-depth). Practical requirements on the mesh spacing $Δx/d_i$ are suggested to bound these errors from above.
