description: Farmland values have recently increased dramatically in the Midwest, attracting investors from outside of agriculture and causing many inside agriculture to question whether a speculative bubble has formed. This article addresses that question by presenting an economic by presenting an economic assessment of the facts related to farmland values across regions of the United States to give a more complete outlook for Midwestern farmland prices. After presenting an analysis of farmland values, this article concludes with discussion of some often-ignored factors that should be at the center of the current debate.

description: We have carried out extensive Monte Carlo simulations of the fusion of tense apposed bilayers formed by amphiphilic molecules within the framework of a coarse grained lattice model. The fusion pathway differs from the usual stalk mechanism. Stalks do form between the apposed bilayers, but rather than expand radially to form an axial-symmetric hemifusion diaphragm of the trans leaves of both bilayers, they promote in their vicinity the nucleation of small holes in the bilayers. Two subsequent paths are observed: (i) The stalk encircles a hole in one bilayer creating a diaphragm comprised of both leaves of the other intact bilayer, and which ruptures to complete the fusion pore. (ii) Before the stalk can encircle a hole in one bilayer, a second hole forms in the other bilayer, and the stalk aligns and encircles them both to complete the fusion pore. Both pathways give rise to mixing between the cis and trans leaves of the bilayer and allow for transient leakage.

Limits to the Cas A $^{44}$Ti Line Flux and Constraints on the Ejecta Energy and the Compact Source

description: Two long observations of Cas A supernova remnant were made by the \emph{Rossi X-ray Timing Explorer} in 1996 and 1997 to search for hard X-ray line emission at 67.9 and 78.4 keV from decay of $^{44}$Ti formed during the supernova event. Continuum flux was detected up to 100 keV, but the $^{44}$Ti lines were not detected. The 90% confidence upper limit to the line flux is 3.6$\times10^{-5}$ photons cm$^{-2}$s$^{-1}$. This is consistent with the recent \emph{BeppoSAX} detection and with the \emph{CGRO}/COMPTEL detection of the companion transition line flux for $^{44}$Sc decay. The mean \emph{BeppoSAX}--COMPTEL flux indicates that 1.5$\pm$0.3 $\times10^{-4}$M$_\odot$ of $^{44}$Ti was produced in the supernova explosion. Based upon recent theoretical calculations, and optical observations suggesting a WN Wolf-Rayet progenitor with an initial mass of $\geq$25 M$_\odot$, the observed $^{44}$Ti yield implies that the Cas A supernova ejecta energy was $\sim2\times10^{51}$ ergs, and as a result a neutron star was formed, rather than a black hole. We suggest Cas A is possibly in the early stages of the AXP/SGR scenario in which the push-back disk has yet to form, and when the disk does form, the accretion will increase the luminosity to that of present-day AXP/SGRs and pulsed emission will commence.

Smooth $μ$-Hybrid and Non-Minimal Higgs Inflation in $SU(4)_{C}\times SU(2)_{L}\times SU(2)_{R}$ With Observable Gravitational Waves

description: We propose to study a smooth variant of the $μ$-hybrid inflation model and a non-minimal Higgs model of inflation with quartic non-minimal coupling between the Higgs field and gravity within the context of a realistic GUT gauge group based on supersymmetric $SU(4)_{C}\times SU(2)_{L}\times SU(2)_{R}$. These models are incorporated with a realistic scenario of reheating and non-thermal leptogenesis, compatible with the constraints from the baryon asymmetry of the universe. Notably, both models successfully address the MSSM $μ$-problem and avoid the issue of primordial magnetic monopoles. Our analysis reveals that both models predict a scalar spectral index $n_s$ that closely aligns with the central observationally favored value of Planck2018 + BICEP2/Keck Array (BK15) data and yield a large tensor-to-scalar ratio ($r > 10^{-3}$), potentially detectable in forthcoming CMB experiments.

description: We studied the unzipping kinetics of single molecules of double-stranded DNA by pulling one of their two strands through a narrow protein pore. PCR analysis yielded the first direct proof of DNA unzipping in such a system. The time to unzip each molecule was inferred from the ionic current signature of DNA traversal. The distribution of times to unzip under various experimental conditions fit a simple kinetic model. Using this model, we estimated the enthalpy barriers to unzipping and the effective charge of a nucleotide in the pore, which was considerably smaller than previously assumed.

Stationary and Transient Work-Fluctuation Theorems for a Dragged Brownian Particle

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: Recently Wang et al. carried out a laboratory experiment, where a Brownian particle was dragged through a fluid by a harmonic force with constant velocity of its center. This experiment confirmed a theoretically predicted work related integrated (I) Transient Fluctuation Theorem (ITFT), which gives an expression for the ratio for the probability to find positive or negative values for the fluctuations of the total work done on the system in a given time in a transient state. The corresponding integrated stationary state fluctuation theorem (ISSFT) was not observed. Using an overdamped Langevin equation and an arbitrary motion for the center of the harmonic force, all quantities of interest for these theorems and the corresponding non-integrated ones (TFT and SSFT, resp.) are theoretically explicitly obtained in this paper. While the (I)TFT is satisfied for all times, the (I)SSFT only holds asymptotically in time. Suggestions for further experiments with arbitrary velocity of the harmonic force and in which also the ISSFT could be observed, are given. In addition, a non-trivial long-time relation between the ITFT and the ISSFT was discovered, which could be observed experimentally, especially in the case of a resonant circular motion of the center of the harmonic force.

description: The equilibrium of a finite-beta RFP plasma in the presence of saturated-amplitude tearing modes is investigated. The singularities of the MHD force balance equation JXB=grad(p) at the modes rational surfaces are resolved through a proper regularization of the zeroth-order (equilibrium) profiles, by setting to zero there the gradient of the pressure and parallel current density. An equilibrium model, which satisfies the regularization rule at the various rational surfaces, is developed. The comparison with the experimental data from the Reversed Field eXperiment (RFX) gives encouraging results. The model provides an easy tool for magnetic analysis: many aspects of the perturbations can be analyzed and reconstructed.

description: Production records for swine producers specializing in niche markets (e.g., natural) are analyzed to determine the factors impacting profitability. The data span a cross section of 42 niche pork producers and record their 2006 production costs. Profitability was measured by the net margin (adjusted for inventory and after all costs) per hundred pounds of pork produced. In comparing the 10 most and 10 least profitable producers, there were statistically significant differences in production costs (feed, labor, and other operational costs) and efficiency (feed conversion, labor intensity, and farrowing frequency). Notably, there was not a statistically significant difference in the price received for market hogs. Multiple regression analysis shows that 82 percent of the variation in profitability across producers is explained by feed costs, labor efficiency, production efficiency, management experience, and the production of more specialized niche pork (e.g., certified organic). Profit margins were negatively impacted by greater feed prices, feed conversion rates, labor intensity, and veterinary expenses. Profit margins were enhanced by greater farrowing efficiency (pigs per litter and farrowings per year), years of niche pork production experience, and the marketing of “certified organic” pork.

description: Due to the spin-orbit coupling, Dirac fermions, submerged in a thermal bath with finite macroscopic vorticity, exhibit a spin polarisation along the direction parallel to the vorticity vector $\boldsymbolΩ$. Due to the symmetries of the Lagrangian for free massless Dirac particles, there are three independent and classically conserved currents corresponding to the vector, axial, and helical charges. The constitutive relations for the charge currents and the stress-energy tensor at thermal equilibrium, derived in the framework of quantum field theory at finite temperature, reveal vorticity-induced contributions that deviate from the perfect fluid form. In this paper, we consider the mode structure of the corresponding hydrodynamical theory and derive collective excitations associated with coherent fluctuations of all three charges. We show that the chirally imbalanced rotating fluid should possess non-reciprocal gapless waves that propagate with different velocities along and opposite to the vorticity vector. We also uncover a strictly unidirectional mode, which we call the Axial Vortical Wave, propagating in the background of the axial charge density. The emergence of this wave can be traced back to earlier studies of vortical chiral fluids in a hydrodynamic approach. We also point out an unexpected instability in the limit of degenerate matter and discuss possible solutions when helicity and axial charge non-conservation are taken into account.

description: In this paper, we consider the effect of interactions on the local, average polarization of a quantum plasma of massless fermion particles characterized by vector, axial, and helical quantum numbers. Due to the helical and axial vortical effects, perturbations in the vector charge in a rotating plasma can lead to chiral and helical charge transfer along the direction of the vorticity vector. At the same time, interactions between the plasma constituents lead to the dissipation of the helical charge through helicity-violating pair annihilation (HVPA) processes and of the axial charge through the axial anomaly. We will discuss separately a QED-like plasma, in which we ignore background electromagnetic fields and thus the axial charge is approximately conserved, as well as a QCD-like plasma, where instanton effects lead to the violation of the axial charge conservation, even in the absence of background chromomagnetic fields. The non-conservation of helicity and chirality leads to a gapping of the Helical, Axial, and mixed Axial-Helical vortical waves that prevents their infrared modes from propagating. On the other hand, usual dissipative effects, such as charge diffusion, lead to significant damping of ultraviolet modes. We end this paper with a discussion of the regimes where these vortical waves may propagate.

description: In this work, we propose a common vector field to study the thermodynamic topology of the Davies type and Hawking-Page phase transitions. Existing literature has shown that studying these two types of phase transitions typically requires defining two separate vector fields . In our approach, we adopt Duan's $ϕ$-mapping topological current theory to define a novel vector field, denoted as $ϕ$, whose critical points exactly correspond to the Davies point and the Hawking-Page phase transition point. More importantly, we can differentiate between these two points by their topological charge. While, the topological charge for the critical point corresponding to the Davies-type phase transition is found to be $-1$, the same for the Hawking-Page phase transition point, it is $+1$. Although our analysis is applicable to all black hole systems where both types of phase transitions are found, we illustrate it using three simple systems as examples: the Schwarzschild AdS black hole, the Reissner-Nordström AdS black hole in the grand canonical ensemble, and finally the Kerr AdS black holes in the grand canonical ensemble. It is wellknown that these black holes exhibit both Davies and Hawking-Page phase transitions. With our proposed vector $ϕ$, the critical points obtained for these three systems exactly match the Davies-type and Hawking-Page phase transition points, and the associated topological charges are found to be $-1$ for the Davies point and $+1$ for the Hawking-Page phase transition point.

Lost revenues were estimated to be $150 million due to 1.2 million acres of slightly saline soils and 275,000 acres of moderate soil salinity.
Kosterlitz-Thouless transition in three-state mixed Potts ferro-antiferromagnets

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We study three-state Potts spins on a square lattice, in which all bonds are ferromagnetic along one of the lattice directions, and antiferromagnetic along the other. Numerical transfer-matrix are used, on infinite strips of width $L$ sites, $4 \leq L \leq 14$. Based on the analysis of the ratio of scaled mass gaps (inverse correlation lengths) and scaled domain-wall free energies, we provide strong evidence that a critical (Kosterlitz-Thouless) phase is present, whose upper limit is, in our best estimate, $T_c=0.29 \pm 0.01$. From analysis of the (extremely anisotropic) nature of excitations below $T_c$, we argue that the critical phase extends all the way down to T=0. While domain walls parallel to the ferromagnetic direction are soft for the whole extent of the critical phase, those along the antiferromagnetic direction seem to undergo a softening transition at a finite temperature. Assuming a bulk correlation length varying, for $T>T_c$, as $ξ(T) =a_ξ\exp [ b_ξ(T-T_c)^{-σ}]$, $σ\simeq 1/2$, we attempt finite-size scaling plots of our finite-width correlation lengths. Our best results are for $T_c=0.50 \pm 0.01$. We propose a scenario in which such inconsistency is attributed to the extreme narrowness of the critical region.

The multiple stellar populations observed in Omega Cen cannot be explained if it had formed as an isolated star cluster. The formation within a progenitor galaxy of the Milky Way is more likely, although the unique properties of Omega Cen still remain a mystery.

Magnetic anisotropy of L1$_0$ FeNi (001), (010), and (111) ultrathin films: A first-principles study

description: In previous experiments, thin films of L1$\mathrm{_0}$ FeNi with different surfaces, including (001), (110) and (111), were produced and studied. Each surface defines a different alignment of the crystallographic tetragonal axis with respect to the film's plane, resulting in different magnetic anisotropies. In this study, we use density functional theory calculations to examine three series of L1$\mathrm{_0}$ FeNi films with surfaces (001), (010), and (111), and with thicknesses ranging from 0.5 to 3 nm (from 4 to 16 atomic monolayers). Our results show that films (001) have perpendicular magnetic anisotropy, while (010) favor in-plane magnetization, with a clear preference for the tetragonal axis [001]. We propose calling this type of in-plane anisotropy fixed in plane. A film with surface (111) and a thickness of four atomic monolayers has the magnetization easy axis almost perpendicular to the plane of the film. As the thickness of the (111) film increases, the direction of magnetization rotates towards a tetragonal axis [001], positioned at an angle of about 45$^{o}$ to the plane of the film. Furthermore, the magnetic moment of ultrathin films increases by a maximum of 5%, and the most significant changes in spin and orbital magnetic moments occur at a depth of about three near-surface atomic monolayers. The presented results could be useful for experimental efforts to synthesize ultrathin L1$\mathrm{_0}$ FeNi films with different surfaces. Ultrathin L1$\mathrm{_0}$ FeNi films with varying magnetic anisotropies may find applications in spintronic devices.

description: Organic light-emitting diodes (OLEDs) have redefined lighting with their environment-friendliness and flexibility. However, only 25 % of the electronic states of organic molecules can emit light upon electrical excitation, limiting the overall efficiency of OLEDs. Strong light-matter coupling, achieved by confining light within OLEDs using mirrors, creates hybrid light-matter states known as polaritons, which could "activate" the remaining 75 % electronic triplet states. Here, we study triplet-to-polariton transition and derive rates for both reverse inter-system crossing and triplet-triplet annihilation. In addition, we explore how the harmful singlet-singlet annihilation could be reduced with strong coupling.

description: A theoretical model of multi-energy radiography (MER) are proposed. It is shown that, as distinct from the conventional radiography, MER allows identification of organic substances and control of their chemical composition. Broad prospects are noted for MER application, specifically, for detection of prohibited substances (explosives, drugs, etc.) during customs and anti-terrorist safety inspection.

description: We have struggled mightily with trying to understand the deeper meaning of our assigned title. What are the critical issues linking diversification of agriculture and international trade? Are they competitive, or even antagonistic, concepts in the broader context of food security and agricultural development? Are they complementary and synergistic and, if so, how? Or are they two ships passing in the night which have little if any linkage? We share our problem in searching for a conceptual framework for the paper with you because we are still not sure we have got it right. We begin with a stylized review of conventional wisdom regarding diversification as a desirable strategy for agricultural development. We then note that much of the agricultural development literature assumes, implicitly or explicitly, a closed or at least closely managed economy. We then ask the question, what happens if you open the economy? Here we use a simple three-good trade model to explore the consequences for the agricultural sector of an open economy setting. We look at the effects on production, consumption and trade as well as the implications for price and income variability and overall economic performance. We then return to the two supposed advantages of a policy of diversification - expanded sources of growth and employment and use as a risk management tool - and ask a basic question: in a world of economy-wide reforms, including trade liberalization, deregulation and privatization, is agricultural diversification a relevant policy objective? To anticipate our answer, we conclude that diversification as a policy goal is not relevant. Those of you who came only for the bottom line can now leave; those who want to know why are invited to stay!

description: We assessed the food security situation in Bangladesh based on 2011-2012 Bangladesh Integrated Household Survey data using two commonly measured indicators: Food Consumption Score (FCS) and Household Hunger Scale (HHS). Results obtained from ordered probit regression models indicated that remittances play an important role to improve the food security of a household. Other significant variables in the model were wage earn outside of farm, male operated household, remittance, and literacy. Increasing income from other than the agriculture sector significantly raises the probability of a household being food secure. Government should make the agriculture sector strong and provide employment opportunities for households to work outside of the farm.

description: Identification of critical source areas (CSAs) helps to reduce best management practices (BMPs) adoption cost to meet the desired level of water quality in a given watershed. We used Soil and Water Assessment Tool (SWAT) to identify critical source areas within the Saline Bayou Watershed (HUC 11140208), Louisiana. SWAT model was calibrated and validated for discharge and sediment pollution. We then followed up with MAPSHED to assess the effectiveness of implementing different best management practices to reduce nutrient and sediment pollution. Optimization results show that nutrient management and agricultural land retirement can reduce most of the phosphorus runoff in the watershed at the lowest cost. Results are robust to change in parameter sensitivity and alternative weather (dry, normal, and wet) scenarios.

description: Farm-level diversification involves adding income-generating activities at the farm household level, including livestock, local non-farm and off-farm pursuits undertaken by farm people. The objective of this paper is to consider questions arising from an apparent inconsistency. In this respect, policy makers seem to consider farm diversification a major 'economic' issue, thus as an objective, while economists typically neglect it, seeing farm diversification as an outcome from pursuing another objective. This lack of a consensus is further reflected by disagreement over the extent to which national policies should proactively seek to promote diversification of the farm-level output mix in specific directions.

description: We introduce infinite dimensional Hilbertian H-type groups equipped with weak, graded, left invariant Riemannian metrics. For these Lie groups, we show that the vanishing of the geodesic distance and the local unboundedness of the sectional curvature coexist. The result validates a deep phenomenon conjectured in an influential 2005 paper by Michor and Mumford, namely, the vanishing of the geodesic distance is linked to the local unboundedness of the sectional curvature. We prove that degenerate geodesic distances appear for a large class of weak, left invariant Riemannian metrics. Their vanishing is rather surprisingly related to the infinite dimensional sub-Riemannian structure of Hilbertian H-type groups. The same class of weak Riemannian metrics yields the nonexistence of the Levi-Civita covariant derivative.

description: Depleting water resources is a widespread problem across the Kansas High Plains aquifer. The value of irrigation is accentuated due to lack of surface water and low precipitation in western Kansas. Accelerated groundwater withdrawals for irrigation caused a further decline in the saturated thickness of the aquifer. To encourage water conservation and reduce further depletion of the aquifer, federal and state cost-share programs have subsidized irrigation technology upgrades. However, this effort may have been undermined by producers who increased their water usage for irrigation with water-intensive crops. A simulation model comprised of an irrigation scheduling tool coupled with a crop yield simulator are used to predict risk-efficient crop and technology choices, which allows us to estimate the effect of an irrigation technology upgrade on the aquifer. This research characterizes producers’ decisions to maintain economic viability while adapting to limited irrigation conditions. The study will identify the conditions under which technology upgrades will both save water and increase farmers’ returns from irrigation. The study also estimates the threshold payments to farmers to switch to relatively less water-intensive crops that will promote water conservation on the High Plains aquifer.

description: Over the last 150 years, agriculture has been subject to several waves of innovation which have significantly altered its institutional structures, its products and the way it is practised. Mechanical, biological and chemical innovations have, in turn, reduced labour requirements, increased yields and reduced the impact of agricultural pests. More recently, computer and remote sensing technologies have improved input precision. Agricultural biotechnology is now emerging as a wellspring of innovations that will reshape agriculture as profoundly as any previous innovation paradigm.' This new technology has unique features which economists need to understand in order to formulate appropriate policy advice. This paper has two main purposes. First, we provide an overview of agricultural biotechnology. There are lessons from medical biotechnology which can be applied to agriculture. In addition, there are new institutions, including technology transfer offices and arrangements for intellectual property rights, which will be introduced and discussed. The second purpose is to introduce some basic analytical considerations and methodological issues which will be important in the study of biotechnology. In particular, these methodologies will relate to the issues in industrial organization associated with the process of product research, development and introduction; issues associated with adoption of biotechnology; and issues associated with pricing. Thus far, commercial biotechnology has been concentrated in the United States, but this technology has important global implications. This paper will examine and project what the American experience implies for the rest of the world and show how biotechnology and its evolution fit within the context of the relationship between developed and developing nations.

description: Despite an apparent progress in implementing individual solid-state qubits, there have been no experimental reports so far on multi-bit gates required for building a real quantum computer. Here we report a new circuit comprising two coupled charge qubits. Using a pulse technique, we coherently mix quantum states and observe quantum oscillations whose spectrum reflects interaction between the qubits. Our results demonstrate the feasibility of coupling of multiple solid-state qubits and indicate the existence of entangled two-qubit states.

description: A study was conducted to investigate the performance of broiler chickens under the intensive and semi- intensive systems of poultry production in Etche Local Government Area of Rivers State. Results of the study revealed significant (P < 0.05) differences in all the parameters investigated between the broilers produced in the two management systems. Birds managed under the intensive systems showed superior performances in average final weight (1,372.25g/bird) as compared to those managed in the semi-intensive system (1,161.25g/bird). The daily weight gains of the birds were also significantly (P < 0.05) different, with the birds in the intensive group showing better performance. The superiority in final weight observed in the intensively managed broilers further reflected in their dressing percentage and primal cuts. In contrast, broilers managed under the semi-intensive system possessed superior internal organs on account of the exposure of the birds to varying environmental condition and feeds they utilized as they scavenge. Hence with the current trend in super market revolution, where the availability of primal cuts of broilers and internal organs are a major means of sales of the chicken in Nigeria, better management of the birds to bring about better production of primal parts and internal organs is advocated.

description: Credit is a strategic empowerment tool that has the potential to change the life of a person, family or community from a situation of abject poverty to a more dignified life. It can transform self-image, unlock potential and boost the productivity and well-being of the poor and vulnerable, especially farmers. This paper estimates the determinants of credit demand by farmers and supply by Rural Banks in the Upper East Region of Ghana. Semi-structured questionnaire complimented by key informant interviews and focus group discussions were used in gathering data from 250 farmers in 5 districts of Upper East Region. The logit model was used to estimate the determinants of credit demand by farmers and the Tobit model used to estimate the determinants of credit supply by Rural Banks. The findings showed that age of farmers, gender and political affiliations among others are the main determinants of credit demand by farmers. Type of crop grown, farm size and the amount of savings made are some determinants of credit supply by the Rural Banks. It is concluded that demand for credit by farmers and supply of it by Rural Banks in Ghana‟s Upper East Region are determined by socio-economic and politico-cultural factors. It is recommended that government; the Bank of Ghana and the Rural Banks themselves should develop strategies that aim at enhancing the positive determinants of credit demand and supply and mitigating the negative ones to ensure credit widening and deepening among farmers.
