description: The expected benefits from herbicide resistant transgenic rice in Uruguay are estimated with stochastic simulation techniques. Economic surplus methods that account for private profits are used to measure the magnitude and distribution of the benefits between producers and a multinational firm. Further, the adoption rate of transgenic rice is endogenous in the model and depends on the expected profitability of the technology. The results show that the potential benefits from the technology are relatively small because of the small production base. Multinational firms are, therefore, unlikely to develop locally adapted transgenic rice varieties without strategic partnerships with local institutions.
Sugawara form for AdS superstring

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

description: We show that the stress-energy tensor for a superstring in the AdS5xS5 background is written in a supersymmetric generalized "Sugawara" form. It is the "supertrace" of the square of the right-invariant current which is the Noether current satisfying the flatness condition. The Wess-Zumino term is taken into account through the supersymmetric gauge connection in the right-invariant currents, therefore the obtained stress-energy tensor is kappa invariant. The integrability of the AdS superstring provides an infinite number of the conserved "local" currents which are supertraces of the n-th power of the right-invariant current. For even n the "local" current reduces to terms proportional to the Virasoro constraint and the kappa symmetry constraint, while for odd n it reduces to a term proportional to the kappa symmetry constraint .

description: We study the effect of the voltage bias on the ferromagnetic phase transition in a one-dimensional itinerant electron system. The applied voltage drives the system into a nonequilibrium steady state with a non-zero electric current. The bias changes the universality class of the second order ferromagnetic transition. While the equilibrium transition belongs to the universality class of the uniaxial ferroelectric, we find the mean-field behavior near the nonequilibrium critical point.

description: We present a method for computing projective isomorphisms between rational surfaces that are given in terms of their parametrizations. The main idea is to reduce the computation of such projective isomorphisms to five base cases by modifying the parametric maps such that the components of the resulting maps have lower degree. Our method can be used to compute affine, Euclidean and Möbius isomorphisms between surfaces.

description: Superconducting circuits are currently developed as a versatile platform for the exploration of many-body physics, by building on non-linear elements that are often idealized as two-level qubits. A classic example is given by a charge qubit that is capacitively coupled to a transmission line, which leads to the celebrated spin-boson description of quantum dissipation. We show that the intrinsic multilevel structure of superconducting qubits drastically restricts the validity of the spin-boson paradigm due to phase localization, which spreads the wavefunction over many charge states. Numerical Renormalization Group simulations also show that the quantum critical point moves out of the physically accessible range in the multilevel regime. Imposing charge discreteness in a simple variational state accounts for these multilevel effects, that are relevant for a large class of devices.

description: The threat of avian influenza and the 2004-2005 influenza vaccine supply shortage in the United States has sparked a debate about optimal vaccination strategies to reduce the burden of morbidity and mortality caused by the influenza virus. We present a comparative analysis of two classes of suggested vaccination strategies: mortality-based strategies that target high risk populations and morbidity-based that target high prevalence populations. Applying the methods of contact network epidemiology to a model of disease transmission in a large urban population, we evaluate the efficacy of these strategies across a wide range of viral transmission rates and for two different age-specific mortality distributions. We find that the optimal strategy depends critically on the viral transmission level (reproductive rate) of the virus: morbidity-based strategies outperform mortality-based strategies for moderately transmissible strains, while the reverse is true for highly transmissible strains. These results hold for a range of mortality rates reported for prior influenza epidemics and pandemics. Furthermore, we show that vaccination delays and multiple introductions of disease into the community have a more detrimental impact on morbidity-based strategies than mortality-based strategies. If public health officials have reasonable estimates of the viral transmission rate and the frequency of new introductions into the community prior to an outbreak, then these methods can guide the design of optimal vaccination priorities. When such information is unreliable or not available, as is often the case, this study recommends mortality-based vaccination priorities.

description: A survey of commercial feeder cattle operations in Utah revealed that explicit transaction costs such as transportation, shrink, and commissions can not fully explain how marketing alternatives are selected. Implicit transaction costs appear to play a critical role in the determination of market selection. For example, the level of trust between buyer and seller and the socio-economic characteristics of market participants are determinants of which marketing method will be used to sell feeder cattle.

description: Changing product characteristics are causing U.S. seed corn companies to reevaluate their inventory strategies. A simulation model based upon the Economic Order Quantity model is built in @Risk to reflect a shortened product life cycle and product proliferation. Inventory costs levels increase because of increased uncertainty of demand. Empirical results find that shortening the product life cycle and expanding the product line increases total inventory costs by 120.8%, increases the average inventory level (primarily due to added safety stock) by 56.2%, and increases the cost of carryover, stockout cost, and safety stock cost by 143, 165, and 119 %, respectively. To maintain higher levels of customer service with products displaying shorter life cycles, more safety stock must be held to guard against stockouts.

The method is based on Fourier sampling of the time-of-flight images through two consecutive impulsive Raman pulses. For applications of this method, we discuss a few examples, including detection of phase separation between superfluid and Mott insulators, various types of spin or superfluid orders, entanglement, exotic or fluctuating orders.

description: The purpose of this paper is to incorporate semiparametric alternatives to maximum likelihood estimation and inference in the context of unordered multinomial response data when in practice there is often insufficient information to specify the parametric form of the function linking the observables to the unknown probabilities. We specify the function linking the observables to the unknown probabilities using a very general flexible class of functions belonging to the Pearson system of cumulative distribution equations. In this setting we consider the observations as arising from a multinomial distribution characterized by one of the CDFs in the Pearson system. Given this situation, it is possible to utilize the concept of unbiased estimating functions (EFs), combined with the concept of empirical likelihood (EL) to define an (empirical) likelihood function for the parameter vector based on a nonparametric representation of the sample's PDF. This leads to the concept of maximum empirical likelihood (MEL) estimation and inference, which is analogous to parametric maximum likelihood methods in many respects.

description: The superconducting circuit community has recently discovered the promising potential of superinductors. These circuit elements have a characteristic impedance exceeding the resistance quantum $R_\text{Q} \approx 6.45~\text{k}Ω$ which leads to a suppression of ground state charge fluctuations. Applications include the realization of hardware protected qubits for fault tolerant quantum computing, improved coupling to small dipole moment objects and defining a new quantum metrology standard for the ampere. In this work we refute the widespread notion that superinductors can only be implemented based on kinetic inductance, i.e. using disordered superconductors or Josephson junction arrays. We present modeling, fabrication and characterization of 104 planar aluminum coil resonators with a characteristic impedance up to 30.9 $\text{k}Ω$ at 5.6 GHz and a capacitance down to $\leq1$ fF, with low-loss and a power handling reaching $10^8$ intra-cavity photons. Geometric superinductors are free of uncontrolled tunneling events and offer high reproducibility, linearity and the ability to couple magnetically - properties that significantly broaden the scope of future quantum circuits.

description: Concentration in the beef packing industry has been rising for the past 25 years. Many studies of market power in beef packing are based on the conjectural variations framework, which depends on accurate estimates of packer input and processing costs. We propose an alternative measure of packer behavior which does not rely on estimates of packer costs. We also suggest how this measure could be used to draw tentative conclusions regarding packer behavior.

description: A realistic two-center shell model for fusion is proposed, which is based on two spherical Woods-Saxon potentials and the potential separable expansion method. This model describes the single-particle motion in a fusing system. A technique for calculating stationary diabatic states is suggested which makes use of the formal definition of those states, i.e., they minimize the radial nonadiabatic coupling between the adiabatic states. As an example the system $^{16}$O + $^{40}$Ca $\to$ $^{56}$Ni is discussed.

description: Since the inevitability in experimental synthesis, defects show great importance to many materials. They will deeply regulate the properties of the materials, and then affect the further applications. Thus, exploring the effects of defects on the properties of materials is desired. Here, by using first-principles calculations, we systematically studied the effect of silicon vacancy defects on the properties of silicene generated on Nterminated cubic boron nitride (111) surface. It is found that the introduction of silicon vacancy would trigger transition between half-metal and ferromagnetic semiconductor. With small vacancy ratios of 1/36 and 1/24, the ground-state of the samples would behave as ferromagnetic semiconductors, and the band gaps are about 1.25 and 0.95 eV, respectively. When the vacancy ratio is increased up to 1/6, the sample would turn into a ferromagnetic half-metal with a half-metallic gap of around 0.15 eV. The change of the electronic structure of the samples is driven by the different electron transfer between silicon layer and substrate, i.e., there will be different amount of electrons transferred from the silicon layer to the substrate when the vacancy ratio is altered. This work would open a new way to regulate the properties of materials and extend applications in nanoelectronic field.

description: [Objectives] This study aimed to determine the volatile components in Santalum album linn and gradually clarify the aroma composition of S. album linn. [Methods] Solid-phase microextraction method was used to obtain the volatile components of S. album linn. The aroma components were analyzed by gas chromatography-mass spectrometry and their relative contents were calculated using the area normalization method. [Results] In a dry state at room temperature, 39 chemical components were identified from S. album linn, mainly olefins (91.15%), alkanes (3.00%), alcohols (2.56%), esters (2.19%), ketones (0.55%), aldehydes (0.41%) and heterocyclics (0.14%). [Conclusions] This method has the advantages of low sample consumption, easy operation, rapid identification of aroma components and high sensitivity, and can effectively separate and determine volatile components in S. album linn, realizing the rapid identification of different S. album linn varieties and providing technical support for further research on Chinese medicinal materials.
The survival of sentient beings
Creators: name: Inglis, John Malyon
Publisher: name: University of British Columbia
Year: 2009

description: This thesis is concerned with the metaphysical question of in what our survival consists. To survive in the sense to be explored herein is for there to be future experiences about which one should be egoistically (as opposed to altruistically) concerned. I focus on one's survival as a sentient being, a being capable of having experiences but possibly lacking some of the attributes of a person. There are two categories into which metaphysical theories of survival fall: reductionist theories (theories according to which survival can be analyzed in terms of physical continuity and/or qualitative relations) and nonreductionist theories. I argue that theories of the former type conflict with our deeply-held and welljustified beliefs about our survival. Reductionist theories cannot explain why one should be specially concerned about certain future experiences. If survival cannot be analyzed in reductionist terms, then we cannot fully refute skepticism about our survival over time. However, as nonreductionist alternatives to skepticism, I briefly consider the traditional substance view (according to which one's survival consists in the persistence of one's ego) and a view according to which one's survival consists in the continuation of one's stream of consciousness. I conclude by briefly enumerating the difficulties that this latter view would have to meet.

description: In the gauge theory of gravity based on the Poincare group (the semidirect product of the Lorentz group and the spacetime translations) the mass (energy-momentum) and the spin are treated on an equal footing as the sources of the gravitational field. The corresponding spacetime manifold carries the Riemann-Cartan geometric structure with the nontrivial curvature and torsion. We describe some aspects of the classical Poincare gauge theory of gravity. Namely, the Lagrange-Noether formalism is presented in full generality, and the family of quadratic (in the curvature and the torsion) models is analyzed in detail. We discuss the special case of the spinless matter and demonstrate that Einstein's theory arises as a degenerate model in the class of the quadratic Poincare theories. Another central point is the overview of the so-called double duality method for constructing of the exact solutions of the classical field equations.

description: We study the possibility to explain the non-baryonic dark matter abundance and improve the present fits on the muon anomalous magnetic moment through the same new physics. The only viable way to solve simultaneously both problems which is known to date is by using supersymmetric theories. However in this work we show that massive brane fluctuations (branons) in large extra-dimensions models can provide a more economical alternative to supersymmetry. This is so because the low-energy branon physics depends effectively on only three parameters. Next collider experiments, such as LHC or ILC, will be sensitive to branon phenomenology in the natural parameter region where the theory is able to account for the two effects.

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

description: We propose a new basis in Witten's open string field theory, in which the star product simplifies considerably. For a convenient choice of gauge the classical string field equation of motion yields straightforwardly an exact analytic solution that represents the nonperturbative tachyon vacuum. The solution is given in terms of Bernoulli numbers and the equation of motion can be viewed as novel Euler--Ramanujan-type identity. It turns out that the solution is the Euler--Maclaurin asymptotic expansion of a sum over wedge states with certain insertions. This new form is fully regular from the point of view of level truncation. By computing the energy difference between the perturbative and nonperturbative vacua, we prove analytically Sen's first conjecture.

description: Feinstratigraphische, tektonische und allgemein-geologische Beobachtungen werden mitgeteilt. Im Röt lassen sich noch nicht alle charakteristischen Horizonte von Ostthüringen nachweisen. Im unteren Muschelkalk wurde eine Anzahl der von Jena bekannten Horizonte neu ermittelt, u. a. die Bänke d2, d3, fi, f4, die Schichten mit Myo. incurvata, die untere und obere Querplattungszone. Für andere, wie den konglomeratischen Wellenkalk, die Oolithbank ß und f3 werden neue Fundstellen angegeben. Die Oolithbank a läßt sich nicht klar festlegen. Die Terebratelzone ist in der Gesamtmächtigkeit nicht konstant, die Schaumkalkbänke wechseln in Stärke und teilweise auch Ausbildung. Der untere Muschelkalk von Stadtilm entspricht der Ostthüringer Ausbildung weitgehend, doch machen sich Abweichungen in der Mächtigkeit einzelner Stufen geltend. Im mittleren Muschelkalk fallen örtlich Zellenkalke und -dolomite auf. In mm ist auch der Gips in den oberflächennahen Gebieten meist ausgelaugt, was sich morphologisch auswirkt. Ein Profil des Überganges nach mo1 wird beschrieben. In mo2 mangelt es an besseren Aufschlüssen. Der untere Keuper nimmt größere Gebiete als bisher bekannt ein und zeigt typische Gesteinsausbildungen, u. a. den Guthmannshäuser Kalk. Diluviale Ablagerungen der Ilm sind stellenweise ziemlich mächtig - Alluvialer Kalktuff ist verbreitet bei Kl.-Hettstedt. Einige tektonische Bilder aus der Eichenberg— Saalfelder Störungszone werden beschrieben. Die südliche Remdaer Störungszone reicht bis zum Ilmtal, die nördliche findet möglicherweise ihre Fortsetzung weit nach NW hin. Auch rheinisch verlaufende Störungen sind wahrscheinlich. Ursache für „Abgänge“ an Muschelkalkhängen ist die Gleitbewegung auf den liegenden wasserstauenden Schichten. Strudeltaschen sind im Muschelkalk recht häufig. Als Füllung solcher Taschen und anderer Spalten spielen u. a. Kalkspatausscheidungen eine Rolle, die lokal auch oberflächlich in auffallenden Resten erhalten sind.

description: A long standing question in range management concerns the relative importance of the stocking rate versus the length of time during which animals graze a particular rangeland. We address this question by analyzing the problem faced by a private rancher who wishes to minimize the long run expected net unit cost (LRENC) from range operations by choosing either the stocking rate or the length of time during which his animals graze his rangeland. We construct a renewal-theoretic model and show that, in general, this rancher's LRENC with an optimally chosen stocking rate is lower than his LRENC with an optimally chosen grazing cycle length.

description: We derived an exact solution of the spherically symmetric Hayward black hole surrounded by perfect fluid dark matter (PFDM). By applying the Newman-Janis algorithm, we generalized it to the corresponding rotating black hole. Then, we studied the shadows of rotating Hayward black hole in PFDM. The apparent shape of the shadow depends upon the black hole spin $a$, the magnetic charge $Q$ and the PFDM intensity parameter $k$ ($k<0$). The shadow is a perfect circle in the non-rotating case ($a=0$) and a deformed one in the rotating case ($a\neq{0}$). For a fixed value of $a$, the size of the shadow increases with the increasing $\vert{k}\vert$, but decreases with the increasing $Q$. We further investigated the black hole emission rate. We found that the emission rate decreases with the increasing $\vert{k}\vert$ (or $Q$) and the peak of the emission shifts to lower frequency. Finally, we discussed the observational prospects corresponding to the supermassive black hole $\mathrm{Sgr\ A^{*}}$ at the center of the Milky Way.

We find that the result of CMBR measurements does not exclude the nonzero value of parameter $B$, but allows it in the range $-0.35\lesssim B\lesssim0.025$.

description: In periodic quantum systems which are both homogeneously tilted and driven, the interplay between drive and Bloch oscillations controls transport dynamics. Using a quantum gas in a modulated optical lattice, we show experimentally that inhomogeneity of the applied force leads to a rich new variety of dynamical behaviors controlled by the drive phase, from self-parametrically-modulated Bloch epicycles to adaptive driving of transport against a force gradient to modulation-enhanced monopole modes. Matching experimental observations to fit-parameter-free numerical predictions of time-dependent band theory, we show that these phenomena can be quantitatively understood as manifestations of an underlying inhomogeneity-induced phase space structure, in which topological classification of stroboscopic Poincaré orbits controls the transport dynamics.

Two different materials and three different buckling slendernesses were investigated. An FE model was created and calibrated using the experimental results. Subsequently, a parameter study was carried out in order to be able to cover a larger buckling slenderness range. The experimental and numerical results were then compared with the specifications of EN 1993-1-4 and an assessment of the specifications is provided.

description: he most popular farming method. [Methods] Based on the climate and soil conditions in Zhaoqing, this experiment explored the improved mode of no-tillage intercropping winter potato with citrus in the new high-ridge, wide-row and dense-plant cultivation mode citrus orchard. Taking the conventional tillage and film-mulched intercropping as the control, it studied the adaptability of intercropping, evaluated the quality, and analyzed its economic benefits. [Results] The early emergence rate of improved no-tillage intercropping cultivation was slightly higher than that of conventional tillage and film-mulched intercropping, but the difference of final emergence rate was not significant, indicating that improved no-tillage intercropping cultivation could provide excellent potato emergence environment. Under the conventional tillage and improved no-tillage intercropping cultivation mode, the change trend of the potato's plant height, main stem thickness, crown diameter and number of leaflet is the same. The change rule of the crown diameter of the film-mulched intercropping cultivation method is similar to that of the plant height, both have a large increase in the late growth stage. The potato yield of improved no-tillage intercropping cultivation were 22 747.5 kg/ha, and the proportions of potatoes of each grade were 11.85%, 35.61%, 37.63% and 14.91%, respectively. The content of dry matter, Vc, soluble protein, starch and amino acid in the main nutrients of the potato under the improved no-tillage intercropping model is not significantly different from that of the film-mulched intercropping cultivation. The changing trend of reducing sugar content showed that the reducing sugar content of no-tillage intercropping cultivation was the highest (0.466%). Through evaluating the eating characteristics of potatoes from the flavor, taste, texture and appearance after chewing, the three cultivation methods have little difference. In the no-tillage intercropping cultivation technology, the growth of potatoes consumes part of the nutrients in the soil between the rows of the citrus orchard, but it does not exerts a significant impact on the surrounding citrus trees. Compared with the film-mulched intercropping cultivation, the improved no-tillage intercropping cultivation method does not require the expense of mulched, the cost of fertilizer is low, and labor costs are saved, so a net income of 27 075 yuan/ha can be obtained. [Conclusions] From the perspective of orchard intercropping, it has achieved the effect of improving soil utilization and increasing output without reducing the edible quality of potatoes.

description: In this paper, we address the issue of financial constraints in agricultural cooperatives. We estimate an augmented Q investment model for a large sample of US agricultural cooperatives and test whether cooperative investment is sensitive to cash flow. Empirical results suggest that agricultural cooperatives are indeed financially constrained when making investment decisions.
The SU(N) Matrix Model at Two Loops

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

description: Multi-loop calculations of the effective action for the matrix model are important for carrying out tests of the conjectured relationship of the matrix model to the low energy description of M-theory. In particular, comparison with N-graviton scattering amplitudes in eleven-dimensional supergravity requires the calculation of the effective action for the matrix model with gauge group SU(N). A framework for carrying out such calculations at two loops is established in this paper. The two-loop effective action is explicitly computed for a background corresponding to the scattering of a single D0-brane from a stack of N-1 D0-branes, and the results are shown to agree with known results in the case N=2.

description: It appears to be widely believed that returns on low quality land are more variable than on high quality land. Using Ricardian rent as the measure of returns and sensitivity to output price as the measure of volatility, we investigate this null hypothesis for three different measures of quality. These are proximity to market, output productivity, and cost efficiency. In all cases, we identify precise conditions on the production technology such that rental volatility varies in a monotone manner with land quality. A method of econometric investigation of the relationship between rental volatility and land quality is developed and applied to Iowa cash rents data collected during 1994-2000. Our preliminary findings provide partial empirical support for the null hypothesis of an inverse relationship between quality and rental volatility with respect to commodity prices.

description: In light of the improved sensitivities of cosmological observations, we examine the status of quasi-degenerate neutrino mass scenarios. Within the simplest extension of the standard cosmological model with massive neutrinos, we find that quasi-degenerate neutrinos are severely constrained by present cosmological data and neutrino oscillation experiments. % % We find that Planck 2018 observations of cosmic microwave background (CMB) anisotropies disfavour quasi-degenerate neutrino masses at $2.4$ Gaussian $σ$'s, while adding Baryon acoustic oscillations (BAO) data brings the rejection to 5.9$σ$'s. % The highest statistical significance with which one would be able to rule out quasi-degeneracy would arise if the sum of neutrino masses is $Σm_ν= 60$ \meV (the minimum allowed by neutrino oscillation experiments); % indeed a sensitivity of 15 meV, as expected from a combination of future cosmological probes, would further improve the rejection level up to 17$σ$. % We discuss the robustness of these projections with respect to assumptions on the underlying cosmological model, and also compare them with bounds from $β$ decay endpoint and neutrinoless double beta decay studies.

description: As with many environmental issues, debates about increasing public conservation lands in the Northern Forest region frequently center on a perceived tradeoff between jobs and the environment. In particular, opponents of conservation lands often argue that employment will decline significantly when land is diverted from commodity-oriented uses such as wood products production. To evaluate this claim, we estimate a model of simultaneous employment and net migration growth using data on the 92 non-metropolitan counties comprising the region. Growth in employment and net migration are measured over the period 1990 to 1997 and the set of exogenous variables includes the 1990 share of the county land base in public conservation uses. We find that net migration rates were systematically higher in counties with more conservation lands, but the effects are relatively small. Public conservation lands were found to have no systematic effect on employment growth over the 1990 to 1997 period. Two extensions are considered. We examine the separate effects of preservationist and multiple-use lands. We also identify a "natural experiment" involving changes in national forest management that allows us to estimate the effects of diverting private forestland to public conservation uses. Our central conclusions are that existing public conservation lands have a positive, but small, effect on employment and migration in the Northern Forest region and that, over the range of our data, employment and migration are unlikely to be affected by timber harvest reductions resulting from the establishment of new conservation lands.
