description: We perform a numerical study of the heat transfer and flow structure of Rayleigh-Bénard (RB) convection in (in most cases regular) porous media, which are comprised of circular, solid obstacles located on a square lattice. This study is focused on the role of porosity $ϕ$ in the flow properties during the transition process from the traditional RB convection with $ϕ=1$ (so no obstacles included) to Darcy-type porous-media convection with $ϕ$ approaching 0. Simulations are carried out in a cell with unity aspect ratio, for the Rayleigh number $Ra$ from $10^5$ to $10^{10}$ and varying porosities $ϕ$, at a fixed Prandtl number $Pr=4.3$, and we restrict ourselves to the two dimensional case. For fixed $Ra$, the Nusselt number $Nu$ is found to vary non-monotonously as a function of $ϕ$; namely, with decreasing $ϕ$, it first increases, before it decreases for $ϕ$ approaching 0. The non-monotonous behaviour of $Nu(ϕ)$ originates from two competing effects of the porous structure on the heat transfer. On the one hand, the flow coherence is enhanced in the porous media, which is beneficial for the heat transfer. On the other hand, the convection is slowed down by the enhanced resistance due to the porous structure, leading to heat transfer reduction. For fixed $ϕ$, depending on $Ra$, two different heat transfer regimes are identified, with different effective power-law behaviours of $Nu$ vs $Ra$, namely, a steep one for low $Ra$ when viscosity dominates, and the standard classical one for large $Ra$. The scaling crossover occurs when the thermal boundary layer thickness and the pore scale are comparable. The influences of the porous structure on the temperature and velocity fluctuations, convective heat flux, and energy dissipation rates are analysed, further demonstrating the competing effects of the porous structure to enhance or reduce the heat transfer.

description: Crude oil prices have been fluctuating over time and by a large range. It is the disorganization of oil price series that makes it difficult to deduce the changing trends of oil prices in the middle- and long-terms and predict their price levels in the short-term. Following a price-state classification and state transition analysis of changing oil prices from January 2004 to April 2010, this paper first verifies that the observed crude oil price series during the soaring period follow a Markov Chain. Next, the paper deduces the changing trends of oil prices by the limit probability of a Markov Chain. We then undertake a probability distribution analysis and find that the oil price series have a log-normality distribution. On this basis, we integrate the two models to deduce the changing trends of oil prices from the short-term to the middle- and long-terms, thus making our deduction academically sound. Our results match the actual changing trends of oil prices, and show the possibility of re-emerging soaring oil prices.

description: Stochastic differential equations (sdes) play an important role in physics but existing numerical methods for solving such equations are of low accuracy and poor stability. A general strategy for developing accurate and efficient schemes for solving stochastic equations in outlined here. High order numerical methods are developed for integration of stochastic differential equations with strong solutions. We demonstrate the accuracy of the resulting integration schemes by computing the errors in approximate solutions for sdes which have known exact solutions.

description: The effect of annealing at 250 C on the carrier depth profile, Mn distribution, electrical conductivity, and Curie temperature of (Ga,Mn)As layers with thicknesses > 200 nm, grown by molecular-beam epitaxy at low temperatures, is studied by a variety of analytical methods. The vertical gradient in hole concentration, revealed by electrochemical capacitance-voltage profiling, is shown to play a key role in the understanding of conductivity and magnetization data. The gradient, basically already present in as-grown samples, is strongly influenced by post-growth annealing. From secondary ion mass spectroscopy it can be concluded that, at least in thick layers, the change in carrier depth profile and thus in conductivity is not primarily due to out-diffusion of Mn interstitials during annealing. Two alternative possible models are discussed.

description: NASA's WB-57 High Altitude Research Program provides a deployable, mobile, stratospheric platform for scientific research. Airborne platforms are of particular value for making coronal observations during total solar eclipses because of their ability both to follow the Moon's shadow and to get above most of the atmospheric airmass that can interfere with astronomical observations. We used the 2017 Aug 21 eclipse as a pathfinding mission for high-altitude airborne solar astronomy, using the existing high-speed visible-light and near-/mid-wave infrared imaging suite mounted in the WB-57 nose cone. In this paper, we describe the aircraft, the instrument, and the 2017 mission; operations and data acquisition; and preliminary analysis of data quality from the existing instrument suite. We describe benefits and technical limitations of this platform for solar and other astronomical observations. We present a preliminary analysis of the visible-light data quality and discuss the limiting factors that must be overcome with future instrumentation. We conclude with a discussion of lessons learned from this pathfinding mission and prospects for future research at upcoming eclipses, as well as an evaluation of the capabilities of the WB-57 platform for future solar astronomy and general astronomical observation.

description: We had been gradually working towards building a comprehensive quarkonia suppression formalism to explain all 3 dependencies of quarkonium suppression obtained from heavy-ion collision experiments. We present here the improved version of quarkonia suppression framework. It assumes bottomonia produced in the early stage which dissociates due to color screening, gluonic dissociation, and collisional damping in addition to the shadowing as an initial state effect. The QGP medium formed in the collisions is assumed to evolve under ($3+1$)-dimensional relativistic viscous hydrodynamics which is modeled using ECHO-QGP. This replaces the Bjorken's hydrodynamics which we had used in our earlier work where we determined the centrality and transverse momentum dependent suppression. The correlated bottom quark and bottom anti-quark could recombine in the plasma. A rate equation is employed, whose solution gives the final number of bottomonium after dissociation and recombination under $(3+1)$-dimensional expansion of the QGP medium. The Shadowing effect, which is the dominant Cold Nuclear Matter effect at LHC energies, has now been modified by employing the most recent parton distribution functions obtained from CT14 global analysis and shadowing factors from EPPS16. Using this improved formalism we determine the centrality, transverse momentum, and rapidity, dependencies of bottomonium suppression for $Υ(1S)$, and $Υ(2S)$ at the LHC's energies of $2.76$ TeV and $5.02$ TeV. We find a fairly good agreement between theoretically calculated survival probability and the measured nuclear modification factor($R_{AA}$) at the two energies.

A local formulation of lattice Wess-Zumino model with exact $\U(1)_R$ symmetry

description: A lattice Wess-Zumino model is formulated on the basis of Ginsparg-Wilson fermions. In perturbation theory, our formulation is equivalent to the formulation by Fujikawa and Ishibashi and by Fujikawa. Our formulation is, however, free from a singular nature of the latter formulation due to an additional auxiliary chiral supermultiplet on a lattice. The model posssesses an exact $\U(1)_R$ symmetry as a supersymmetric counterpart of the Lüscher lattice chiral $\U(1)$ symmetry. A restration of the supersymmetric Ward-Takahashi identity in the continuum limit is analyzed in renormalized perturbation theory. In the one-loop level, a supersymmetric continuum limit is ensured by suitably adjusting a coefficient of a single local term $\tilde F^*\tilde F$. The non-renormalization theorem holds to this order of perturbation theory. In higher orders, on the other hand, coefficents of local terms with dimension $\leq4$ that are consistent with the $\U(1)_R$ symmetry have to be adjusted for a supersymmetric continuum limit. The origin of this complexicity in higher-order loops is clarified on the basis of the Reisz power counting theorem. Therefore, from a view point of supersymmetry, the present formulation is not quite better than a lattice Wess-Zumino model formulated by using Wilson fermions, although a number of coefficients which require adjustment is much less due to the exact $\U(1)_R$ symmetry. We also comment on an exact non-linear fermionic symmetry which corresponds to the one studied by Bonini and Feo; an existence of this exact symmetry itself does not imply a restoration of supersymmetry in the continuum limit without any adjustment of parameters.

description: In most developing countries, historically, the main strategy for improving the food sector has focused on increasing farm-level production. But in recent years, with the emphasis on value chain analysis, there has been much more focus on subsector studies, demand-driven approaches, and improving vertical coordination to assure product quality to final consumption markets. Millet, sorghum, and later rice were the traditional leading three cereal crops produced and consumed in Mali. Maize has trailed them for more than two decades, but from mid 1990s on, it has been produced and consumed in much larger quantities. Given the potentials of maize, developing and better organizing its subsector has the potential to not only increase revenues for maize farmers, but also create profitable opportunities for other actors in the subsector (traders, marketers, processors, industries, and consumers). This paper seeks to provide a description of the changing supply and demand dynamics for maize in Mali, the organization of the marketing channels and players, and the characteristics of the main consumption markets. The main conceptual tools to be used are subsector analysis and the structure-conduct-performance (SCP) approach. The paper will draw on literature reviews, the author’s personal interviews with value chain participants, and tabular and graphical analysis of production and price data to address the reasons behind the changes in production and demand, how the demand is likely to evolve, how the structure of the subsector might be affected, and what will be the implications for public sector investments and policies.

description: We construct an overlapping generations model in which agents live through two periods; childhood and adulthood. Each agent makes choices only as an adult, based on her utility that depends on her own consumption and the human capital and environmental quality endowed to her offspring. Entering adulthood, agents choose randomly between two occupations: citizens and politicians. Citizens are the only producers of a single good and choose the proportion of their income to declare to the tax authorities. Politicians decide upon the allocation of the tax revenue between environmental protection and education activities, taking as given the rates of peculation in each activity. In this context, two self-fulfilling stable equilibria can emerge, one associated with high and another with low corruption. Corrupted politicians induce high levels of tax evasion, reducing total public funds and thus environmental protection activities. This result is in accordance with existing empirical evidence and implies that environmental policies may fail in corrupt countries where they are used as means of supporting rent seeking activities instead of protecting the environment. A higher level political authority could intervene and force the low corruption equilibrium by choosing the appropriate tax rate and, through institutional changes, the rates of peculation.

description: The Diels-Alder cycloaddition, in which a diene reacts with a dienophile to form a cyclic compound, counts among the most important tools in organic synthesis. Achieving a precise understanding of its mechanistic details on the quantum level requires new experimental and theoretical methods. Here, we present an experimental approach that separates different diene conformers in a molecular beam as a prerequisite for the investigation of their individual cycloaddition reaction kinetics and dynamics under single-collision conditions in the gas phase. A low- and high-level quantum-chemistry-based screening of more than one hundred dienes identified 2,3-dibromobutadiene (DBB) as an optimal candidate for efficient separation of its gauche and s-trans conformers by electrostatic deflection. A preparation method for DBB was developed which enabled the generation of dense molecular beams of this compound. The theoretical predictions of the molecular properties of DBB were validated by the successful separation of the conformers in the molecular beam. A marked difference in photofragment ion yields of the two conformers upon femtosecond-laser pulse ionization was observed, pointing at a pronounced conformer-specific fragmentation dynamics of ionized DBB. Our work sets the stage for a rigorous examination of mechanistic models of cycloaddition reactions under controlled conditions in the gas phase.

description: The aim of the paper is to present evidence that China and India are, and will remain, two very different actors in international negotiations to control global warming. We base our conclusions on historical data and on scenarios until 2050. The Business-as-Usual scenario (BaU) is compared to four Emissions Tax scenarios to draw insights on major transformations in energy use and in energy supply and to assess the possible contribution of China and India to a future international climate architecture. We study whether or not the Copenhagen intensity targets require more action than the BaU scenario and we assess whether the emissions reductions induced by the four tax scenarios are compatible with the G8 and MEF pledge to reduce global emissions by 50% in 2050.

description: Consider the problem of tracking a set of moving targets. Apart from the tracking result, it is often important to know where the tracking fails, either to steer sensors to that part of the state-space, or to inform a human operator about the status and quality of the obtained information. An intuitive quality measure is the correlation between two tracking results based on uncorrelated observations. In the case of Bayesian trackers such a correlation measure could be the Kullback-Leibler difference. We focus on a scenario with a large number of military units moving in some terrain. The units are observed by several types of sensors and "meta-sensors" with force aggregation capabilities. The sensors register units of different size. Two separate multi-target probability hypothesis density (PHD) particle filters are used to track some type of units (e.g., companies) and their sub-units (e.g., platoons), respectively, based on observations of units of those sizes. Each observation is used in one filter only. Although the state-space may well be the same in both filters, the posterior PHD distributions are not directly comparable -- one unit might correspond to three or four spatially distributed sub-units. Therefore, we introduce a mapping function between distributions for different unit size, based on doctrine knowledge of unit configuration. The mapped distributions can now be compared -- locally or globally -- using some measure, which gives the correlation between two PHD distributions in a bounded volume of the state-space. To locate areas where the tracking fails, a discretized quality map of the state-space can be generated by applying the measure locally to different parts of the space.

description: This article challenges the conventional result that a tighter environmental tax has no long-run effect on human capital accumulation in the presence of pollution arising from final output production. It demonstrates that the technology used in the abatement sector determines the existence and the direction of the growth-effect. A tighter environmental tax rises (respectively reduces) human capital accumulation in the presence of pollution arising from final production, if the abatement sector is relatively more intensive in human (resp. physical) capital than final sector. That result always holds for finite lifetime but for infinite lifetime it only holds when labor supply is endogenous. The transitional impact of a tighter environmental policy is also investigated.

description: We investigate time-dependent electron current through a quantum dot under external drive (pulses), coupled to leads at zero bias. Simple analytic expressions for current, generated by periodic pulses of any shape, are obtained without any use of the Floquet expansion. We demonstrate that the current, follows a local quench, displays the transient and steady-state behavior, which are described by the same universal function of an external drive. The results are applied for an analysis of the current generated by rectangular and linear form pulses, in comparison with ultra-fast pulses of very high amplitude. Our results are also applicable for study of On-Demand Single-Electron sources and laser driven junctions.

Since there is currently no legislation or discharge regulations specific to DLS runoff (as for pulp and paper effluents), polluting DLS operations have largely gone unnoticed and as a result few treatment technologies have been tested. In this study, twelve samples of DLS runoff were taken from three dry land sorts located on the Sunshine Coast of British Columbia. Samples had chemical oxygen demand (COD) ranging from 346 mg/L to 3690 mg/L (of twelve samples tested), pH and metals (of two samples tested) that did not comply with British Columbia (BC) Approved Water Quality Guidelines and the BC Municipal Sewage Regulations. The particles of two samples were characterized chemically and morphologically and it was determined that fresh DLS runoff contains highly aggregated inorganic and organic colloidal particles ranging from 1 to 10 pm in size. Although some of these particles sedimented during storage at 4 °C or 25 °C, most particles remained relatively stable in suspension suggesting the requirement for filtration or a secondary treatment process. An oxide-coated sand filtration process performed well over three series of' column experiments, removing up to 86% of the COD and 92% of the turbidity, when operated as a re-circulating filter for 24 hours. Batch adsorption experiments using the oxide-coated sand removed averages of 17% and 26% DLS runoff COD over two series of experiments. The same sand, however with the oxide-coating stripped (oxidestripped sand), failed to remove COD from solution in batch adsorption experiments suggesting that the oxide-coating enhanced absorption of suspended particles. When oxide-stripped sand filters were run in parallel with oxide-coated sand filters treating successive batches of DLS runoff, the oxide-stripped sand treated on average 34% less COD and 32% less turbidity. Neither flocculation nor biological activity was determined to be an important mechanism to the sand filtration process over successive batch treatment runs.

description: Positron lifetime spectra were measured in liquid water at temperatures between 0c and 50c. The long lifetime of ortho-positronium atoms (o-Ps) determined by electron pick-off in molecular substances decreases smoothly by 10% as the temperature is raised. This lifetime temperature dependence can be explained by combining the Ps-bubble model and the mixture state model of liquid water.

description: The objective of this study is to evaluate and model the yield risk associated with major agricultural commodities in the U.S. We are particularly concerned with the nonstationary nature of the yield distribution, which primarily arises because of technological progress and changing environmental conditions. Precise risk assessment depends on the accuracy of modeling this distribution. This problem becomes more challenging as the yield distribution changes over time, a condition that holds for nearly all major crops. A common approach to this problem is based on a two-stage method in which the yield is first detrended and then the estimated residuals are treated as observed data and modeled using various parametric or nonparametric methods. We propose an alternative parametric model that allows the moments of the yield distributions to change with time. Several model selection techniques suggest that the proposed time-varying model outperforms more conventional models in terms of in-sample goodness-of-fit, out-of- sample predictive power and the prediction accuracy of insurance premium rates.

description: One of the main threats to wild primates is habitat alteration, fragmentation and destruction. Therefore it is crucial to understand the ability of those species to adapt to human-induced habitat changes to prevent extirpation. Key to this is a species diet plasticity. In Paraguay over 91% of the Upper Paraná Atlantic Forest has been destroyed to expand agricultural land. We determined the diet composition of three Sapajus cay groups in degraded and near-pristine Atlantic Forest in eastern Paraguay to assess whether the diet composition of this species changes with habitat degradation. We accounted for diet variability associated with demographic traits and forest characteristics using multinomial linear models. Once the effect of age, sex, and season were accounted for, we found that the diet of capuchins was plastic and shifted to adapt to studied degraded forest conditions. The results showed that (as expected) the capuchins have a generalist and flexible diet, including opportunistically taking advantage of crop plants, particularly Slash Pine plantations, when the risks were lower. The capuchins ability to adjust their diet in different habitat fragments demonstrates that small islands of Paraguayan Atlantic Forest are valuable for their persistence. This insight can be used to create applied conservation strategies, such as using the existing Payment for Ecosystem Services (PES) legislation to provide an opportunity to begin reconnecting fragments using native trees bordered by Slash Pine plantations. Using the capuchins as an umbrella species would increase public support of the program, while compensation through the PES scheme and profiting from the timber would encourage landowner participation.

description: Differential graded algebra invariants are constructed for Legendrian links in the 1-jet space of the circle. In parallel to the theory for R^3, Poincare-Chekanov polynomials and characteristic algebras can be associated to such links. The theory is applied to distinguish various knots, as well as links that are closures of Legendrian versions of rational tangles. For a large number of two-component links, the Poincare-Chekanov polynomials agree with the polynomials defined through the theory of generating functions. Examples are given of knots and links which differ by an even number of horizontal flypes that have the same polynomials but distinct characteristic algebras. Results obtainable from a Legendrian satellite construction are compared to results obtainable from the DGA and generating function techniques.

description: Ground is a grand system; it is in fact a grand system of smaller integrated systems that function independently, but also interplay symbiotically, synchronously and harmoniously. Ground relies on these interactions and not necessarily survival of any one component. Here we will show how manmade sinkholes are the result of disturbance to these natural systems, and how ground in future cities will be engineered to have adaptable, responsive, and constantly evolving components. Components that are self-healing, self-producing, “self-placing-into-the-open” and self-forming. A grand system in which there is no separation between genotype and phenotype, waste in one system is food in another system. A circular system.

description: The generation of high-order harmonics in quasi-one-dimensional graphene nanoribbons (GNRs) initiated by intense coherent radiation is investigated. A microscopic theory describing the extreme nonlinear optical response of GNRs is developed. The closed set of differential equations for the single-particle density matrix at the GNR-strong laser field multiphoton interaction is solved numerically. The obtained solutions indicate the significance of the bandgap width and Fermi energy level on the high-order harmonic generation process in GNRs.

description: Several imputation approaches under a large sample and different levels of censoring are compared and contrasted by using a multiple imputation methodology. The study not only discusses imputation approaches, but also quantifies differences in price variability before and after price imputation, evaluates the performance of each method, and estimates and compares parameters from a complete demand system. The study’s findings reveal that even when there is small variability among different price imputation approaches, there may be large variability among the underlying parameter estimates of interest and the ultimately desired measures. This suggests that a multiple imputation approach may be preferred over a comparison of mean prices among various imputation approaches.
