description: This paper analyses food demand patterns of Indonesian households from a resource intensity perspective, and quantifies the impact of changed demand patterns on the use of three major resource inputs -fossil fuel, land and water – in agricultural production. 13 major food items are categorised into low, moderate and high resource intensity, and income elasticity and Engel curves are estimated for the period from 1997 to 2007. Additional resource use due to changes in demand is quantified by controlling for real expenditure growth over the study period as well as consumption and budget share changes. The results show that income growth in Indonesia is associated with demand patterns that are more resource intensive. Per capita requirements of fossil fuel, land and water increased by 3.13(MJ), 1.24(m2) and 2.1(KL) respectively relative to 1997 unit consumption levels. This study shows that at least for Indonesia, economic development will enhance challenges surrounding resource management, given the increased pressure on natural resource use resulting from food demand. The approach provides a useful foundation for further study into other developing countries similar to Indonesia in affirming connections between economic development and food demand that is more resource intensive.

description: A self consistent theory of a cigar shaped Bose-Einstein condensate (BEC) periodically modulated by a laser beam is presented. We show, both theoretically and numerically, that modulational instability/stability is the mechanism by which wavefunctions of soliton type can be generated in cigar shaped BEC subject to a 1D optical lattice. The theory explains why bright solitons can exist in BEC with positive scattering length and why condensate with negative scattering length can be stable and give rise to dark solitary pulses.

Edwards measure and the steady state regime of a model with kinetic constraints under tapping

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

description: We study the tapping dynamics of a one dimensional Ising model with symmetric kinetic constraints. We define and test a variant of the Edwards hypothesis that one may build a thermodynamics for the steady state by using a flat measure over the metastable states with several macroscopic quantities fixed. Various types of tapping are compared and the accuracy of this measure becomes quickly excellent when the number of quantities fixed on average increases, independently of the way the system is excited. We attribute the validity of the naive flat measure at weak tapping to the spatial separation of density defects.

description: We investigate the case for environmental quenching of the Fornax-mass satellite DDO 113, which lies only 9 kpc in projection from its host, the Large-Magellanic-Cloud-mass galaxy NGC 4214. DDO 113 was quenched about 1 Gyr ago and is virtually gas-free, while analogs in the field are predominantly star-forming and gas-rich. We use deep imaging obtained with the Large Binocular Telescope to show that DDO 113 exhibits no evidence of tidal disruption to a surface brightness of $μ_V\sim29$ mag $\text{arcsec}^{-2}$, based on both unresolved emission and resolved stars. Mass-analogs of DDO 113 in Illustris-1 with similar hosts, small projected separations, and no significant tidal stripping first fell into their host halo 2--6 Gyr ago, showing that tidal features (or lack thereof) can be used to constrain infall times in systems where there are few other constraints on the orbit of the satellite. With the infall time setting the clock for environmental quenching mechanisms, we investigate the plausibility of several such mechanisms. We find that strangulation, the cessation of cold gas inflows, is likely the dominant quenching mechanism for DDO 113, requiring a time-averaged mass-loading factor of $η=6-11$ for star-formation-driven outflows that is consistent with theoretical and observational constraints. Motivated by recent numerical work, we connect DDO 113's strangulation to the presence of a cool circumgalactic medium (CGM) around NGC 4214. This discovery shows that the CGM of low-mass galaxies can affect their satellites significantly and motivates further work on understanding the baryon cycle in low-mass galaxies.

description: Unlike in the United States where fertility is found to be negatively correlated with female labor force participation, China has witnessed a decrease in both fertility and female labor force participation since the 1980s. Does fertility play a different role in female labor force participation in China than in the U.S.? To answer this question, this paper exploits plausibly exogenous variations in fertility created by the afffirmative One-Child Policy in China to estimate the effect of having two or more children on the mother's labor force participation. Using a large data set from the 1990 Population Census, we find that though OLS shows positive effects of fertility, 2SLS will report negative effects of having two or more children on female labor force participation in rural China.
Multifractal stationary random measures and multifractal random walks with log-infinitely divisible scaling laws

description: We define a large class of continuous time multifractal random measures and processes with arbitrary log-infinitely divisible exact or asymptotic scaling law. These processes generalize within a unified framework both the recently defined log-normal Multifractal Random Walk (MRW) [Bacry-Delour-Muzy] and the log-Poisson "product of cynlindrical pulses" [Barral-Mandelbrot]. Our construction is based on some ``continuous stochastic multiplication'' from coarse to fine scales that can be seen as a continuous interpolation of discrete multiplicative cascades. We prove the stochastic convergence of the defined processes and study their main statistical properties. The question of genericity (universality) of limit multifractal processes is addressed within this new framework. We finally provide some methods for numerical simulations and discuss some specific examples.

description: Using a sample of $\simeq$144,000 quasars from the Sloan Digital Sky Survey data release 14 we investigate the outflow properties, evident both in absorption and emission, of high-ionization Broad Absorption Line (BAL) and non-BAL quasars with redshifts 1.6 $\lesssim z \leq$ 3.5 and luminosities 45.3 $< \log_{10}(L_{bol}) < $ 48.2 erg s$^{-1}$. Key to the investigation is a continuum and emission-line reconstruction scheme, based on mean-field independent component analysis, that allows the kinematic properties of the CIV$λ$1550 emission line to be compared directly for both non-BAL and BAL quasars. CIV-emission blueshift and equivalent-width (EW) measurements are thus available for both populations. Comparisons of the emission-line and BAL-trough properties reveal strong systematic correlations between the emission and absorption properties. The dependence of quantitative outflow indicators on physical properties such as quasar luminosity and luminosity relative to Eddington-luminosity are also shown to be essentially identical for the BAL and non-BAL populations. There is an absence of BALs in quasars with the hardest spectral energy distributions (SEDs), revealed by the presence of strong HeII$λ$1640 emission, large CIV$λ$1550-emission EW and no measurable blueshift. In the remainder of the CIV-emission blueshift versus EW space, BAL and non-BAL quasars are present at all locations; for every BAL-quasar it is possible to identify non-BAL quasars with the same emission-line outflow properties and SED-hardness. The co-location of BAL and non-BAL quasars as a function of emission-line outflow and physical properties is the key result of our investigation, demonstrating that (high-ionization) BALs and non-BALs represent different views of the same underlying quasar population.

description: This paper uses a complicated set of phase-ins and phase-outs of oxygenated motor fuel in the Northeast to determine whether E-10 ethanol-enhanced fuel contributes to acetaldehyde air pollution over the pre-ethanol methyl tertiary-buthyl ether (MTBE) fuel. Oil companies phased out MTBE because of groundwater pollution concerns, and now E-10 is the standard fuel in EPA reformulated gas areas. Using a difference-in-difference setup, I find a small level increase but a large percentage increase in acetaldehyde pollution with E-10. I also compute a cost of the pollution in the single-digit millions of dollars. The findings concur with many scientific papers estimating that the impact of E-10 fuel on acetaldehyde pollution is small but positive.

description: Purpose: To evaluate whether a methanolic extract of Ocimum basilicum (OB) leaves prevented lenticular protein alterations in an in-vitro model of selenite-induced cataractogenesis. Materials and Methods: Transparent lenses extirpated from Wistar rats were divided into three groups: control; selenite only; treated. Control lenses were cultured in Dulbecco’s modified Eagle’s medium (DMEM) alone, selenite only lenses were cultured in DMEM containing sodium selenite only (100 µM selenite/ml DMEM) and treated lenses were cultured in DMEM containing sodium selenite and the methanolic extract of OB leaves (200 µg of extract/ml DMEM); all lenses were cultured for 24 h and then processed. The parameters assessed in lenticular homogenates were lenticular protein sulfhydryl and carbonyl content, calcium level, insoluble to soluble protein ratio, sodium dodecyl sulphate-polyacrylamide gel electrophoretic (SDS-PAGE) patterns of lenticular proteins, and mRNA transcript and protein levels of αA-crystallin and βB1-crystallins. Results: Selenite only lenses exhibited alterations in all parameters assessed. Treated lenses exhibited values for these parameters that were comparable to those noted in normal control lenses. Conclusions: The methanolic extract of OB leaves prevented alterations in lenticular protein sulfhydryl and carbonyl content, calcium level, insoluble to soluble protein ratio, SDS-PAGE patterns of lenticular proteins, and expression of αA-crystallin and βB1-crystallin gene and proteins in cultured selenite-challenged lenses. OB may be further evaluated as a promising agent for the prevention of cataract.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

Quantum confinement in CdSe nanocrystallites

description: Quantum confinement increases the spacing between energy levels as the nanocrystallite size is decreased. Its qualitative features hold both for states localized near the center of a nanocrystallite and those near the surface, such as states due primarily to dangling bonds. However, different quantitative features are expected because of the different size constraints on each of these states. Since the majority of atoms in a typical nanocrystallite are on the surface, contrasting confinement effects between these two types may prove useful in predicting how surface state dependent properties, such as optical absorption, change with the size of the nanocrystallite. By applying first principles pseudopotential methods to indium doped, uncapped CdSe nanocrystallites containing 17 and 34 atoms, we identify center and surface localized states. Using the lowest occupied energy state as a reference, the energy of a state localized near the center is found to increase 24 mRy from the 34 to 17 atom nanocrystallite. An equivalent surface state within the two cases studied is not found, but the energy level spacing is speculated to increase on the order of 100 mRy between the 34 and 17 atom cases based on states that are highly local to the surface, but not equivalent. Furthermore, we find it's necessary for the impurity to sit at the center of the nanocrystallite in order for the impurity states to be electrically active.

description: A meta-analysis of reported water demand elasticities shows that publication selection bias results in water demand estimates that overstate price elasticities. The analysis uses panel data estimators to measure and adjust for publication bias. A random effects estimator is used to derive water demand elasticity estimates that are efficient and unbiased by selection effects. The sample mean elasticity for reported elasticities is -.37%. Once publication bias is removed, the mean elasticity estimate drops to -.08%. Indoor water demand is almost perfectly inelastic. Water demands and their elasticities are heterogeneous in specific uses and locations. Water demand elasticities vary by location, water use type, econometric approach and publication bias. Water use elasticities range up -1.48% for domestic irrigation demand in the southwestern US. Estimated elasticities are also higher when derived with discrete choice data and estimators.

description: In 2011 and 2012 severe droughts caused extensive damage in crops throughout the Midwest. These conditions combined with concerns for climate change have led to a growing focus on risk management in agriculture. The increasing emphasis on risk management is reflected in the 2014 Farm Bill, which replaces direct payments with shallow loss programs. For this paper we turn our attention to winter wheat production in Kansas and explore the ratings of the crop insurance policies as well as predicted payouts from the new Agricultural Risk Coverage program established under the 2014 Farm Bill. Using spatial models we simulate yields of non-irrigated winter wheat and irrigated winter wheat to estimate crop insurance premium rates as well as payouts from the Agricultural Risk Coverage program.

This paper describes how the sample was selected, presents examples of images and seeing corrected fits to the observed surface brightness profiles, describes our method for estimating K-corrections, and shows that the SDSS spectra are of sufficiently high quality to measure velocity dispersions accurately. It also provides catalogs of the measured photometric and spectroscopic parameters. In related papers, these data are used to study how early-type galaxy observables, including luminosity, effective radius, surface brightness, color, and velocity dispersion, are correlated with one another.

description: Bernoulli's free boundary problem is an overdetermined problem in which one seeks an annular domain such that the capacitary potential satisfies an extra boundary condition. There exist two different types of solutions called elliptic and hyperbolic solutions. Elliptic solutions are ``stable'' solutions and tractable by variational methods and maximum principles, while hyperbolic solutions are ``unstable'' solutions of which the qualitative behavior is less known. We introduce a new implicit function theorem based on the parabolic maximal regularity, which is applicable to problems with loss of derivatives. Clarifying the spectral structure of the corresponding linearized operator by harmonic analysis, we prove the existence of foliated hyperbolic solutions as well as elliptic solutions in the same regularity class.

description: We consider the finite volume mean values of current operators in integrable spin chains with local interactions, and provide an alternative derivation of the exact result found recently by the author and two collaborators. We use a certain type of long range deformation of the local spin chains, which was discovered and explored earlier in the context of the AdS/CFT correspondence. This method is immediately applicable also to higher rank models: as a concrete example we derive the current mean values in the SU(3)-symmetric fundamental model, solvable by the nested Bethe Ansatz. The exact results take the same form as in the Heisenberg spin chains: they involve the one-particle eigenvalues of the conserved charges and the inverse of the Gaudin matrix.

 Lebia Latreille, 1802: Histoire naturelle, générale et particulière des crustacés et des insectes. Ouvrage faisant suite à l’histoire naturelle générale et particulière, composée par Leclerc de Buffon, et rédigée par C. S. Sonnini, membre de plusieurs sociétés savantes. Familles naturelles des genres. Tome troisième: 85. Type species: Carabus haemorrhoidalis Fabricius, 1792 (= Buprestis marginatus Geoffroy in Fourcroy, 1785), by subsequent designation (Andrewes, 1935).
 The very large genus Lebia (s. l.) is distributed worldwide with a large number of species described from the Oriental region.Authors differ in how the genus should be subdivided, or, whether it should be retained as a single genus. However, this is a matter of opinion about the supraspecific hierarchY which will not be discussed herein in detail.
 Unfortunately no general revision of the Oriental species of the genus Lebia is available, because the paper of Jedlicka (1963) includes only a part of the then described species and, moreover, does not use genitalic characters for characterization and differentiation of the species; and the key in Habu (1967) covers only the Japanese species.
 The matter has recently been made worse, because Kirschenhofer in a couple of papers (e.g., Kirschenhofer, 2009a,b) described various, mostly very similar, species from the Oriental Region, either from single females, or if males are involved, without describing or figuring the internal structures of the aedeagus which in many Lebia are very characteristic and complex, because the internal sac may bear variously shaped and located teeth, spines, or spinose plates. This taxonomic procedure does not really improve our knowledge and renders work on this genus rather more difficult.
 Therefore, unfortunately, the internal structures of the male genitalia of almost no Oriental Lebia have been examined, which makes identification of species difficult. Sorting of species only using body size, shape, and colour pattern as differentiating characters is compromized bY the presence of several very similarly shaped and coloured species, and also infraspecific variation in some widelY ranging species.
The Papuan species have been keyed by Darlington (1968) in his monumental treatise of the New Guinean Carabidae, and the species of the Australian and Papuan Regions were recently revised by Baehr (2004a), who added several species in a number of supplementary papers, of which that from 2012 (Baehr, 2012c) for the present paper is most important.

description: The zinc finger structure where a Zn2+ ion binds to 4 cysteine or histidine amino acids in a tetrahedral structure is very common motif of nucleic acid binding proteins. The corresponding interaction model is present in 3% of the genes of human genome. As a result, zinc finger has been shown to be extremely useful in various therapeutic and research capacities, as well as in biotechnology. In stable configuration, the cysteine amino acids are deprotonated and become negatively charged. This means the Zn2+ ion is overscreened by 4 cysteine charges (overcharged). It is question of whether this overcharged configuration is also stable when such negatively charged zinc finger binds to negatively charged DNA molecule. Using all atom molecular dynamics simulation up to microsecond range of an androgen receptor protein dimer, we investigate how the deprotonated state of cysteine influences its structure, dynamics, and function in binding o DNA molecules. Our results show that the deprotonated state of cysteine residues are essential for mechanical stabilization of the functional, folded conformation. Not only this state stabilizes the protein structure, it also stabilizes the protein-DNA binding complex. The differences in structural and energetic properties of the two (sequence-identical) monomers are also investigated showing the strong influence of DNA on the structure of zinc fingers upon complexation. Our result has potential impact on better molecular understanding of one of the most common classes of zinc fingers

description: In this paper we interpret and explain in more detail the economic analysis contained in our report, The Public Interest and Private Economic Power: A Case Study of the Northeast Dairy Compact. This paper contains a graphic deconstruction of the price analysis that is presented in that report. It also focuses on evidence for the conclusions that Stop & Shop was a price leader in the market power game and that Garelick and private label demand are sufficiently inelastic to support a leadership role for Suiza Foods Inc. Before moving directly to the Report, let us briefly look more generally at the issue of farm-to-retail price transmission in milk markets. Figure 1 displays the retail price and the farm level price for the San Francisco market area. Note how fluctuation in the farm level price is transmitted forward to fluctuation in the retail price in a fairly regular and consistent fashion. This is a textbook example of how farm prices in a competitive channel affect retail prices.

description: I develop a theory of combined exciton-cyclotron resonance (ExCR) in a low-density two-dimensional electron gas in high magnetic fields. In the presence of excess electrons an incident photon creates an exciton and simultaneously excites one electron to higher-lying Landau levels. I derive exact ExCR selection rules that follow from the existing dynamical symmetries, magnetic translations and rotations about the magnetic field axis. The nature of the final states in the ExCR is elucidated. The relation between ExCR and shake-up processes is discussed. The double-peak ExCR structure for transitions to the first electron Landau level is predicted.

description: Our study focuses on modeling Colorado potato beetle (CPB) outbreaks and damage caused in Maine. The approach is to evaluate CPB outbreak frequency in a spatio-temporal framework. A block bootstrapping method with has been used to evaluate the CPB damage on a experimental field of potatoes. With this approach, impacts of environmental factors on CPB outbreaks and implications of crop rotations are assessed. Some explanatory variables, including temperature, crop rotations and soil minerals have been detected to have significant impacts. Consequently, our method offers a way to design spatial layout to minimize the risks of CPB outbreaks, given the current environmental information of a field.

description: In this survey we consider mathematical models and methods recently developed to control crowd dynamics, with particular emphasis on egressing pedestrians. We focus on two control strategies: The first one consists in using special agents, called leaders, to steer the crowd towards the desired direction. Leaders can be either hidden in the crowd or recognizable as such. This strategy heavily relies on the power of the social influence (herding effect), namely the natural tendency of people to follow group mates in situations of emergency or doubt. The second one consists in modify the surrounding environment by adding in the walking area multiple obstacles optimally placed and shaped. The aim of the obstacles is to naturally force people to behave as desired. Both control strategies discussed in this paper aim at reducing as much as possible the intervention on the crowd. Ideally the natural behavior of people is kept, and people do not even realize they are being led by an external intelligence. Mathematical models are discussed at different scales of observation, showing how macroscopic (fluid-dynamic) models can be derived by mesoscopic (kinetic) models which, in turn, can be derived by microscopic (agent-based) models.

Probing dark energy using baryonic oscillations in the galaxy power spectrum as a cosmological ruler
Creators: name: Blake, Chris
name: Glazebrook, Karl
Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We show that the baryonic oscillations expected in the galaxy power spectrum may be used as a "standard cosmological ruler'' to facilitate accurate measurement of the cosmological equation of state. Our approach involves a straight-forward measurement of the oscillation "wavelength'' in Fourier space, which is fixed by fundamental linear physics in the early Universe and hence is highly model-independent. We quantify the ability of future large-scale galaxy redshift surveys with mean redshifts z~1 and z~3 to delineate the baryonic peaks in the power spectrum, and derive corresponding constraints on the parameter w describing the equation of state of the dark energy. For example, a survey of three times the Sloan volume at z ~ 1 can produce a measurement with accuracy dw ~ 0.1. We suggest that this method of measuring the dark energy powerfully complements other probes such as Type Ia supernovae, and suffers from a different (and arguably less serious) set of systematic uncertainties.

description: After the collapse of the Soviet Union in 1991, Russian economy was on the way to becoming more market-based. While the broadening of market forces in Russian agriculture seems plausible, there is little empirical evidence to support the proportion that land allocation decision among grains and oil-seeds are in large determined by output prices for the crops. The crops are wheat, barley, oats, corn, rye, soybeans, rapeseed, and sunflower. In this chapter, a land allocation model developed recently by Vorotnikova, Asci and Seale (2013) is fit to post-Soviet data to determine if output prices for grains and oil-seeds significantly affect land allocation among these crops and by what magnitudes. We look at the effect of the relative export price changes on allocation of land among top eight top crops in agricultural production for Russia during the years 1992 to 2012. We have determined that most price responsive acreages are those of 1) soybeans, 2) corn, 3) sunflower, 4) wheat, 5) rye, 6) barley, and 7) other. Overall, we can conclude that Russian agriculture has become price responsive when it comes to the land allocation.

description: The interlayer spin correlations in the magnetic/non-magnetic semiconductor superlattices are reviewed. The experimental evidences of interlayer exchange coupling in different all-semiconductor structures, based on neutronographic and magnetic studies, are presented. A tight-binding model is used to explain interaction transfer across the non-magnetic block without the assistance of carriers in ferromagnetic EuS/PbS and antiferromagnetic EuTe/PbTe systems.

description: In this study, the effect of rake angle of a ripper plough on the draft requirement in a sandy-clay soil was investigated. The study was based on field experiments, laboratory tests and numerical simulation. Field experiments were conducted at the University of Nairobi field station in Upper Kabete, Kenya located at 1o15’S and 36o44’E at an altitude of about 1940 m above sea level. The soil at the location is a humic Nitisol belonging to the class of sandy-clay.The numerical model was developed using the principles of the discrete element method embedded in a commercial code. EDEM Academic™ software was applied to model the draft requirement to ripping using ripper tines of rake angles; 30o, 45o, 60o and 75o. The model was calibrated using the results of soil physical tests that included of moisture content, bulk density, sieve analysis, shear strength, cone index and angle of repose. The integrity of the model was validated statistically using empirical data from field tests. The statistical methods utilized included of measures of central tendency, the One Sample Kolmogorov-Smirnov test, analysis of variance, the student t-test and multi-linear regression. The validated model was applied to predict the effect of the rake angle on the draft requirement; the forces arising due to particle and boundary contact during simulation were calculated using an inbuilt contact constitutive relation and displayed using the model’s inbuilt query feature.Statistical analysis indicated that the rake angle significantly influenced the value of the draft requirement in the sandy-clay soil at the 95% level of confidence. The draft requirement to ripping was found to decrease from the rake angle of 30o to a minimum at 45o. The draft requirement then increased through the rake angle of 60o to a maximum at 75o. The rake angle of 45o was found to give the minimum amount of the draft requirement while the rake angle of 75o was found to give the maximum amount of the draft requirement.

description: Soybean farmers continue to face a number of challenges, including a constant environmental threat brought about by prolonged periods of drought. Among the immediate consequences is a diminished crop growth or yield production. Previous experiences of major droughts in the U.S. also resulted in livestock deaths and transformation of fertile land into desserts. Increasing focus is being given to create and develop soybean varieties that are more drought-resistant. The introduction of more drought-resistant soybeans have the potential to provide farmers with improvements in productivity either through improvement in yield, reductions in costs, or both. This would eventually translate into changes in the value of soybeans as well as a response in acreage planted of both the new drought-resistant varieties as well conventional types of varieties. Equally impacted are product derivatives of soybeans as well as other related markets. Given the potential gains and losses to different markets and industries from introducing more drought-resistant soybeans, it is important to evaluate how welfare impacts are distributed through the soybean value chain due to the introduction of such new soybean seed technology. We apply comparative static analyses using a multi-market equilibrium displacement model that takes a value chain approach to estimate the economic implications of introducing more drought-resistant soybean seeds into the marketplace.
