description: A preliminary investigation is made of possible applications in quantum theory of the topos formed by the collection of all $M$-sets, where $M$ is a monoid. Earlier results on topos aspects of quantum theory can be rederived in this way. However, the formalism also suggests a new way of constructing a `neo-realist' interpretation of quantum theory in which the truth values of propositions are determined by the actions of the monoid of strings of finite projection operators. By these means, a novel topos perspective is gained on the concept of state-vector reduction.

description: A quantum model for Josephson-based metamaterials working in the Three-Wave Mixing (3WM) and Four-Wave Mixing (4WM) regimes at the single-photon level is presented. The transmission line taken into account, namely Traveling Wave Josephson Parametric Amplifier (TWJPA), is a bipole composed by a chain of rf-SQUIDs which can be biased by a DC current or a magnetic field in order to activate the 3WM or 4WM nonlinearities. The model exploits a Hamiltonian approach to analytically determine the time evolution of the system both in the Heisenberg and interaction pictures. The former returns the analytic form of the gain of the amplifier, while the latter allows recovering the probability distributions vs. time of the photonic populations, for multimodal Fock and coherent input states. The dependence of the metamaterial's nonlinearities is presented in terms of circuit parameters in a lumped model framework while evaluating the effects of the experimental conditions on the model validity.

description: Imaging using interferometer arrays based on the Van Cittert-Zernike theorem has been widely used in astronomical observation. Recently it was shown that superresolution can be achieved in this system for imaging two weak thermal point sources. Using quantum estimation theory, we consider the fundamental quantum limit of resolving the transverse separation of two strong thermal point sources using interferometer arrays, and show that the resolution is not limited by the longest baseline. We propose measurement techniques using linear beam splitters and photon-number-resolving detection to achieve our bound. Our results demonstrate that superresolution for resolving two thermal point sources of any strength can be achieved in interferometer arrays.

description: Albedo estimates from MODIS satellite observations: a revised algorithm provides improved agreement with ground-based observationIt is now recognised that land-cover change contributes to climate change through direct radiation absorption. To quantify this contribution, it is necessary to measure short-wave albedos of different land covers across different seasons and wide spatial areas. The MODIS sensor on board the Terra and Aqua satellites provides estimates of short-wave albedo for the whole earth every eight days and is a useful instrument for this purpose. However, we found that MODIS white-sky albedo estimates included spurious seasonal patterns, whereas black-sky albedo did not adequately reproduce the seasonal patterns observed in ground-based measurements from a pine forest (Pinus radiata) in a snow-free region of New Zealand. The problem may either be caused by the inability of the Ross-Li empirical BRDF model to extrapolate to large exitance angles outside the range of fitting provided by satellite observations, or by too few measurements being available in each observation period (16 days) for the model fitting. It was possible to eliminate these problems by estimating albedo from a more physically based BRDF model (WAK II) fitted to data over a time period much longer than 16 days. The seasonal pattern generated with the revised algorithm removed the spurious seasonal patterns and instead generated seasonal patterns that were consistent with ground observations. White-sky albedo was uniform throughout the year, while black-sky albedo varied with the angle of the sun, with highest values in winter. Mean albedos were 0.12 – 0.13 for pine forest and 0.20 for pasture (Lolium spp.). Most land-use change in New Zealand consists of conversion between pasture and pine forest with consequent albedo changes of 0.075.

description: Hunger is acknowledged to impose a heavy burden on humankind with severe negative health consequences. Micronutrient malnutrition, or "hidden hunger", is an even more widespread problem, to which economic development and income growth alone are not expected to provide a solution any time soon. Existing micronutrient interventions like pharmaceutical supplementation or industrial fortification have their limitations and can be complemented by a new approach: breeding food crops for higher micronutrient densities. Knowledge about the cost-effectiveness of this new tool, also termed biofortification, is scarce. In this study, a framework for economic impact analysis is developed, which is then used for evaluation of iron-rich rice and wheat in India. Health benefits are measured and quantified using "disability-adjusted life years" (DALYs). The impact of biofortification is based on a representative data set of food consumption at the household level. Juxtaposing imputed health benefits with research and development costs proves the cost-effectiveness of the intervention; under pessimistic assumptions saving one healthy life year through biofortification only costs US$ 1.90, a cost which even declines to 36 Cents under optimistic assumptions. Extending the study to include a cost-benefit analysis shows that iron biofortification, with an internal rate of return of 74-152%, can also be a worthwhile public investment.

description: The reflectance of land and vegetation observed in satellite imagery depends on sun and viewing geometry. This bidirectional reflectance requires correction for monitoring changes in vegetation cover and condition. We used a digital camera mounted in a light aircraft, and fitted with a fisheye lens, to measure directional reflectance of a diverse range of landscapes along a long transect in Australia — between Brisbane and the Simpson desert. All, except one, of the measured directional reflectances were able to be characterized accurately (adjusted r2 > 0.95) by the product of two analytical functions.

description: A Bose-Einstein condensate in an optical lattice exhibits parametric resonances when the intensity of the lattice is periodically modulated in time. These resonances correspond to an exponential growth of the population of counter-propagating Bogoliubov excitations. A suitable linearization of the Gross-Pitaevskii (GP) equation is used to calculate the stability diagram and the growth rates of the unstable modes. The results agree with the ones extracted from time-dependent GP simulations, supporting our previous claim (M. Kraemer et al., Phys. Rev. A (2005) in press) concerning the key role of parametric resonances in the response observed by Stoeferle et al. (Phys. Rev. Lett. 92, 130403 (2004)) in the superfluid regime. The role of the seed excitations required to trigger the parametric amplification is discussed. The possible amplification of the quantum fluctuations present in the quasiparticle vacuum, beyond GP theory, is also addressed, finding interesting analogies with similar processes in nonlinear quantum optics and with the dynamic Casimir effect. Our results can be used in exploiting parametric instabilities for the purpose of spectroscopy, selective amplification of a particular excitation mode and for establishing a new type of thermometry.

We show that the category of orientals is isomorphic to a subcategory of the category of chain complexes. This leads to a very simple combinatorial description of the morphisms between orientals. We also show that the category of orientals is the closure of the category of simplexes under certain filler operations which represent complicial operations.

description: A Bayesian hierarchical model was employed to estimate individual expected pricing performance for market advisory programs in corn and soybeans. Performance is defined as the difference between the price/revenue obtained by following the program's marketing recommendations and the average price/revenue offered by the market along the marketing window. The estimates obtained from this model are weighted averages of traditional separate and pooled estimates. Based on the sample employed, the most reasonable individual estimates for expected pricing performance imply a substantial shrinkage towards pooled values. The Bayesian estimates for expected pricing performance range from ¢9/bu to ¢9/bu for corn, from ¢11/bu to ¢17/bu for soybeans and $0.4/acre to $11/acre for revenue. Bayesian estimates are employed in the construction of efficient portfolios of advisory programs. Results suggest that farmers can benefit from following the marketing recommendations of advisory programs portfolios.

description: Host heterogeneity is a key driver of host–pathogen dynamics. In particular, the use of treatments against infectious diseases creates variation in quality among hosts, which can have both epidemiological and evolutionary consequences. We present a general theoretical model to highlight the consequences of different imperfect treatments on pathogen prevalence and evolution. These treatments differ by their action on host and pathogen traits. In contrast with previous studies, we assume that treatment coverage can vary in time, as in seasonal or pulsed treatment strategies. We show that periodic treatment strategies can limit both disease spread and virulence evolution, depending on the type of treatment. We also introduce a new method to analytically calculate the selection gradient in periodic environments, which allows our predictions to be interpreted using the concept of reproductive value, and can be applied more generally to analyse eco-evolutionary dynamics in class-structured populations and fluctuating environments.

description: Results are reported from the complete salt phase of the Sudbury Neutrino Observatory experiment in which NaCl was dissolved in the D$_2$O target. The addition of salt enhanced the signal from neutron capture, as compared to the pure D$_2$O detector. By making a statistical separation of charged-current events from other types based on event-isotropy criteria, the effective electron recoil energy spectrum has been extracted. In units of $ 10^6$ cm$^{-2}$ s$^{-1}$, the total flux of active-flavor neutrinos from $^8$B decay in the Sun is found to be $4.94^{+0.21}_{-0.21}{(stat)}^{+0.38}_{-0.34}{(syst)}$ and the integral flux of electron neutrinos for an undistorted $^8$B spectrum is $1.68^{+0.06}_{-0.06}{(stat)}^{+0.08}_{-0.09}{(syst)}$; the signal from ($ν_x$,e) elastic scattering is equivalent to an electron-neutrino flux of $2.35^{+0.22}_{-0.22}{(stat)}^{+0.15}_{-0.15}{(syst)}$. These results are consistent with those expected for neutrino oscillations with the so-called Large Mixing Angle parameters, and also with an undistorted spectrum. A search for matter-enhancement effects in the Earth through a possible day-night asymmetry in the charged-current integral rate is consistent with no asymmetry. Including results from other experiments, the best-fit values for two-neutrino mixing parameters are $Δm^2 = (8.0^{+0.6}_{-0.4}) \times 10^{-5}$ eV$^2$ and $θ= 33.9 ^{+2.4}_{-2.2}$ degrees.

This general result provides a powerful tool for the representation, reconstruction, and forecasting of chaotic attractors. It also improves previous statements in the literature for differentiable generalized synchronizations, whose existence was so far guaranteed for a restricted family of systems and was detected using Hölder exponent-based criteria.

description: Vier ernste Gesange, Op. 121 (Four Serious Songs) by Johannes Brahms (1833-1897) displays a breathtaking motivic concentration and subtlety. To take just one example, the desolate falling thirds that open the third song are transformed by inversion into assuaging rising sixths at death's final welcoming 'O Tod, wie wohl tust du:' one fundamental idea contemplated from two diametrically opposed standpoints. Concerto written in 1961 by Robert A. Spillman (1948-) was composed while on faculty at the Eastman school in Rochester, New York. Robert Spillman's Concerto is a standard in the repetoire of the bass trombone. With an American style, its open intervals and widely spaced chords follow in the traditions of Aaron Copland and Howard Hanson. Currently teaching in Colorado, Mr. Spillman is an accomplished accompanist as well as a composer. Drei Leichte Stucke, Three Easy Pieces written in 1938 by Paul Hindemith (1895-1963) were likely written for Gertrude Hindemith, who was an amateur cellist. The term 'easy' applies here in that the entire piece is playable in first position on the cello. This should not lead to one assuming that these pieces are trivial, for they are musically charming, gentle, and beautiful. And, though they are not playable in first position on the trombone, they adapt very successfully, providing a light, gentle contrast to the more weighty trombone sonata. Sonata for Bass Trombone - Patrick McCarty (1928-) McCarty was educated at the Eastman school of Music and holds a doctorate (I believe) in Music Theory. This sonata follow the classic fast-slow-fast form and is indicative of the composer's love of modes, which is also characteristic of the predominant style of composition at Eastman during this time period. This sonata is also one of the most played pieces in the Bass Trombone literature and exists in piano and string orchestra versions (source: Jeffrey Reynoldsfrecording of sonata; Tom Everett's Annotated Guide to Bass Trombone Literature; compiled by Barnaby Kerekes)

description: We discuss inflationary solutions of the coupled Einstein-Klein-Gordon equations for a complex field in a five dimensional spacetime with a compact $x^5$-dimension. As a new feature, the scalar field contains a dependence on the extra dimension of the form $\exp(i m x^5) $, corresponding to Kaluza-Klein excited modes. In a four dimensional picture, a nonzero $m$ implies the presence of a new term in the scalar field potential. An interesting feature of these solutions is the possible existence of several periods of oscillation of the scalar field around the equilibrium value at the minimum of the potential. These oscillations lead to cosmological periods of accelerated expansion of the universe.

description: The overall goal of this paper is to contribute to the ongoing assessment of China's rural labor markets. To meet this goal, we have three specific objectives. First, we will provide an update of the trends in off-farm labor participation and wages of the sample households and examine how labor market outcomes have changed for those with different levels of education. Second, we will then seek to examine if education in different time periods - the late 1980s, the early 1990s and the mid 1990s -- can be associated with increasing access to off-farm jobs. Finally, we will examine how returns to education have changed during the course of the reform era. In short, our hypotheses are that if labor markets are increasingly rewarding those with a.) better education job access; b.) easier entry; and c.) higher wages, such outcomes will count as evidence that labor markets are improving. Both the descriptive data and the multivariate analysis robustly support the findings that between the late 1980s and the mid-1990s, labor markets have improved in the sense that rural workers have been increasingly rewarded for their education.

Во многих странах мира в последние годы идет активное внедрение технологий для электронного, часто дистанционного и виртуального обучения. Все это стало возможным благодаря внедрению виртуальных тренажеров и симуляторов, с возможностью моделирования разнообразных клинических случаев. Нами была проведена сравнительная оценка препарирования кариозных полостей студентами IV и V курсов на симуляторе «Леонардо» и на пластмассовых моделях. В итоге проведенного исследования выявлена положительная динамика в обучении студентов навыку препарирования зубов в обоих методах, при этом освоение принципов препарирования оказалось более понятным на симуляторе. Таким образом, при обучении на «Леонардо» нет необходимости работы с реальными пациентами, исключается негативное влияние человеческого фактора, объективно оценивается качество выполненного задания.

description: The method of q-oscillator lattices, proposed recently in [hep-th/0509181], provides the tool for a construction of various integrable models of quantum mechanics in 2+1 dimensional space-time. In contrast to any one dimensional quantum chain, its two dimensional generalizations -- quantum lattices -- admit different geometrical structures. In this paper we consider the q-oscillator model on a special lattice. The model may be interpreted as a two-dimensional Bose gas. The most remarkable feature of the model is that it allows the coordinate Bethe Ansatz: the p-particles' wave function is the sum of plane waves. Consistency conditions is the set of 2p equations for p one-particle wave vectors. These "Bethe Ansatz" equations are the main result of this paper.

description: Recent advances in computational perception have significantly improved the ability of autonomous robots to perform state estimation with low entropy. Such advances motivate a reconsideration of robot decision-making under uncertainty. Current approaches to solving sequential decision-making problems model states as inhabiting the extremes of the perceptual entropy spectrum. As such, these methods are either incapable of overcoming perceptual errors or asymptotically inefficient in solving problems with low perceptual entropy. With low entropy perception in mind, we aim to explore a happier medium that balances computational efficiency with the forms of uncertainty we now observe from modern robot perception. We propose an approach for efficient task planning for goal-directed robot reasoning. Our approach combines belief space representation with the fast, goal-directed features of classical planning to efficiently plan for low entropy goal-directed reasoning tasks. We compare our approach with current classical planning and belief space planning approaches by solving low entropy goal-directed grocery packing tasks in simulation. Our approach outperforms these approaches in planning time, execution time, and task success rate in our simulation experiments. We also demonstrate our approach on a real world grocery packing task with physical robot.

description: The overall goal of our paper is to understand how WTO will affect the agriculture sector in China. To accomplish this goal we have two specific objectives. First, we seek to provide measures of the distortions in China's agricultural sector at a time immediately prior to the nation's accession to WTO. Second, we seek to assess how well integrated China's markets are in order to understand which areas of the country and which segments of the farming population will likely be isolated from or affected by the changes that WTO will bring. Ultimately, with a knowledge of the size and magnitude of the impacts, researchers will be better able to being working on understanding how the policies that WTO will impose on China will change the gap between the domestic and international price and affect imports and exports, domestic production and production, income and poverty. To meet these objectives, the rest of the paper is organized as following. First, we will seek to provide a context for our analysis of the current distortions that affect China's agriculture. Second, after briefly discussing our data and way of collecting information for calculating the gap in prices between international and domestic markets, we present measures of NPRs for a set of commodities for China. The next section then discusses how these distortions should be expected to change as China implements its WTO obligations and gains access (or not) to the promises that were made to it. The fourth section of the paper then analyzes the transmission of prices through the economy. The final section discusses the implication of our findings.

description: Galaxy-galaxy lensing (GGL) measures the 2-point cross-correlation between galaxies and mass in the Universe. In this work we seek to generalise this effect by considering the third-order correlations between galaxies and mass: galaxy-galaxy-galaxy lensing. Third-order correlations in the cosmic shear field have recently been reported in the VIRMOS-DESCART and CTIO surveys. Such data should also be ideal for measuring galaxy-galaxy-galaxy lensing. Indeed, the effects of these higher-order correlations may have already been detected in recent studies of galaxy-galaxy lensing. In this paper we lay out the basic relations for third-order cross correlations and their projections and introduce a new set of scale dependent third-order bias parameters. We define three new observables: two galaxy-shear-shear correlation functions, $G_{\pm}$, and a galaxy-galaxy-shear correlation, ${\cal G}$. We relate these to the various projected cross-bispectra and give practical estimators for their measurement. We note that the observational signature of these correlators is simply the excess shear-shear correlation measured about foreground galaxies (for $G_{\pm}$) and the average tangential shear around foreground galaxy pairs (for $\cal G$). Finally we derive expressions for the third order aperture mass statistics in terms of both the cross-bispectra and the real-space correlation functions. (Abridged)

description: Владение коммуникативными навыками позволяет врачу более эффективно решать лечебно-диагностические и организационные задачи в процессе оказания медицинской помощи пациентам. Коммуникативные навыки это ряд практических приемов, совокупность умений, применение которых в определенных ситуациях и определенной последовательности обеспечивает наилучший результат в выстраивании отношений с пациентом на всех этапах его обращения. Владение навыками общения столь же важно, как и клиническое мышление и владение профессиональными врачебными манипуляциями, так как нередки ситуации, когда пациент может остаться неудовлетворенным лечением у врача, прекрасно владеющего своей профессией, хорошего клинициста и диагноста, из-за низкой коммуникативной компетентности последнего. С 2018 г. в программу первичной аккредитации выпускников медицинских вузов в Российской Федерации в качестве пилотного проекта введена станция объективного структурированного клинического экзамена (ОСКЭ) оценка навыков общения у выпускников. В ходе пилотного проекта были оценены уровень коммуникативной компетентности врача (правильность и последовательность применения коммуникативных навыков в работе со стандартизированным пациентом) и его эффективность в установлении правильного диагноза. Результаты проведенного исследования продемонстрировали взаимосвязь медицинской коммуникации с результативностью выявления клинических синдромов на этапе общения, обозначили острую потребность будущих врачей в оттачивании навыков коммуникации, вплоть до мелочей в ходе обучения, с возможностью включения тренингов по коммуникативным навыкам в обязательную программу всех медицинских вузов.

description: For the past twenty-five years, Dusansky and his associated co-authors have published a longseries of papers which are based on the same price-dependent utility function. The alleged price dependence, however, is fictitious in the sense that the level of exogenous money income can replace the commodity prices. The consequence is that the demand functions derived from Dusansky's utility function are identical and observationally equivalent to the demand functions obtained from a prototypical utility function. Since all the market and environmental effects are revealed only through the demand functions, the specification and use of a utility function such as that used by Dusansky is irrelevant and uninformative for the analysis of any economic problem where prices enter the consumer utility function and whose goal is the detection of the effects of price-dependent preferences on the demand for real goods.

description: We study the conditions under which N=(1,1) generalized sigma models support an extension to N=(2,2). The enhanced supersymmetry is related to the target space complex geometry. Concentrating on a simple situation, related to Poisson sigma models, we develop a language that may help us analyze more complicated models in the future. In particular, we uncover a geometrical framework which contains generalized complex geometry as a special case.

Transport in weighted networks: Partition into superhighways and roads

description: Transport in weighted networks is dominated by the minimum spanning tree (MST), the tree connecting all nodes with the minimum total weight. We find that the MST can be partitioned into two distinct components, having significantly different transport properties, characterized by centrality -- number of times a node (or link) is used by transport paths. One component, the {\it superhighways}, is the infinite incipient percolation cluster; for which we find that nodes (or links) with high centrality dominate. For the other component, {\it roads}, which includes the remaining nodes, low centrality nodes dominate. We find also that the distribution of the centrality for the infinite incipient percolation cluster satisfies a power law, with an exponent smaller than that for the entire MST. The significance of this finding is that one can improve significantly the global transport by improving a tiny fraction of the network, the superhighways.

description: Due to their high coherence, a laser is a ubiquitous tool in science. We show that by engineering the coupling between the gain medium and the laser cavity as well as the laser cavity and the output port, it is possible to eliminate most of the noise due to photons entering as well as leaving the laser cavity. Hence, it is possible to reduce the laser linewidth by a factor equal to the number of photons in the laser cavity below the standard quantum limit. We design and theoretically analyze a superconducting circuit that uses Josephson junctions, capacitors and inductors to implement a microwave laser, including the low-noise couplers that allow the design to surpass the standard quantum limit. Our proposal relies on the elements of superconducting quantum information, and thus is an example of how quantum engineering techniques can inspire us to re-imagine the limits of conventional quantum systems.

description: The overall goal of our paper is to explore this question of how China's policy will likely respond as the nation enters the WTO. Specifically, we will have three objectives. First, we briefly review China's existing agriculture policy and past performance of China's agriculture and how it has changed during the past 20 years of reform. Next, we examine the main features of the agreement that China must adhere to as they enter WTO. Finally, we consider a number of possible ways that policy makers may respond, primarily focusing on the national government's viewpoint.

description: Japan is one of the largest importers of wheat in the world, with imports originating from three countries, Australia, Canada, and the United States. Australia, Canada, and Japan all use a government single-desk agency to control wheat trade. Many previous studies on competition in the world grain trade have argued the market is imperfectly competitive, and they often point to the Japanese market. We study the Japanese wheat import market for this reason, but find no compelling evidence of imperfect competition.
Comments on chiral algebras and $Ω$-deformations

description: Every six-dimensional $\mathcal{N}=(2,0)$ SCFT on $\mathbf{R}^6$ contains a set of protected operators whose correlation functions are controlled by a two-dimensional chiral algebra. We provide an alternative construction of this chiral algebra by performing an $Ω$-deformation~of a topological-holomorphic twist of the $\mathcal{N}=(2,0)$ theory on $\mathbf{R}^6$ and restricting to the cohomology of a specific supercharge. In addition, we show that the central charge of the chiral algebra can be obtained by performing equivariant integration of the anomaly polynomial of the six-dimensional theory. Furthermore, we generalize this construction to include orbifolds of the $\mathbf{R}^4$ transverse to the chiral algebra plane.
Level Shifts and the Illusion of Long Memory in Economic Time Series

description: When applied to time series processes containing occasional level shifts, the logperiodogram (GPH) estimator often erroneously finds long memory. For a stationary short-memory process with a slowly varying level, I show that the GPH estimator is substantially biased, and I derive an approximation to this bias. The asymptotic bias lies on the (0,1) interval, and its exact value depends on the ratio of the expected number of level shifts to a user-defined bandwidth parameter. Using this result, I formulate the Modified GPH estimator, which has a markedly lower bias. I illustrate this new estimator via applications to soybean prices and stock market volatility.

description: We investigate the potential of the so-called XFROG cross-correlation technique originally developed for ultrashort laser pulses for the recovery of the amplitude and phase of the condensate wave function of a Bose-Einstein condensate. Key features of the XFROG method are its high resolution, versatility and stability against noise and some sources of systematic errors. After showing how an analogue of XFROG can be realized for Bose-Einstein condensates, we illustrate its effectiveness in determining the amplitude and phase of the wave function of a vortex state. The impact of a reduction of the number of measurements and of typical sources of noise on the field reconstruction are also analyzed.
