description: We propose a new procedure for parton-to-hadron fragmentation in proton-proton collisions. The hadronization is considered in the parton-parton center-of-mass system and hadrons are assumed to be emitted in the direction of outgoing partons in that frame and then their four-momenta are transformed to the overall center-of-mass system using relevant Lorentz transformations and appropriate distributions are constructed. For heavy hadron production the energy-momentum condition is imposed. In many cases our procedure disagrees with the commonly used rule that rapidity of produced hadron is the same as rapidity of the parent parton. We illustrate the newly proposed scheme for production of $D$ mesons, $Λ_c$ baryon and $η_c$ quarkonium in leading-order approach to parton production. The transverse momentum, rapidity and Feynman-$x_F$ distributions are shown. We consider $c \to D$ and $g \to D$ as well as $c \to η_c$ and $g \to η_c$ hadronization processes. The resulting rapidity distributions are much narrower than those obtained in the traditional approach with parton-hadron rapidity equivalence. This has consequences both for mid- and forward rapidities and could have consequences for high-energy neutrino production in the Earth's atmosphere. We discuss also $c \to Λ_c^+$ and $b \to Λ_c^+$ fragmentation and find that the second mechanism could be partly responsible for the enhanced production of $Λ_c^{\pm}$ observed recently by the ALICE collaboration.

description: The question of optimal portfolio is addressed. The conventional Markowitz portfolio optimisation is discussed and the shortcomings due to non-Gaussian security returns are outlined. A method is proposed to minimise the likelihood of extreme non-Gaussian drawdowns of the portfolio value. The theory is called Leptokurtic, because it minimises the effects from "fat tails" of returns. The leptokurtic portfolio theory provides an optimal portfolio for investors, who define their risk-aversion as unwillingness to experience sharp drawdowns in asset prices. Two types of risks in asset returns are defined: a fluctuation risk, that has Gaussian distribution, and a drawdown risk, that deals with distribution tails. These risks are quantitatively measured by defining the "noise kernel" -- an ellipsoidal cloud of points in the space of asset returns. The size of the ellipse is controlled with the threshold parameter: the larger the threshold parameter, the larger return are accepted for investors as normal fluctuations. The return vectors falling into the kernel are used for calculation of fluctuation risk. Analogously, the data points falling outside the kernel are used for the calculation of drawdown risks. As a result the portfolio optimisation problem becomes three-dimensional: in addition to the return, there are two types of risks involved. Optimal portfolio for drawdown-averse investors is the portfolio minimising variance outside the noise kernel. The theory has been tested with MSCI North America, Europe and Pacific total return stock indices.

description: We generalise the non-affine theory of viscoelasticity for use with large, well-sampled systems of arbitrary chemical complexity. Having in mind predictions of mechanical and vibrational properties of amorphous systems with atomistic resolution, we propose an extension of the Kernel Polynomial Method (KPM) for the computation of the vibrational density of states (VDOS) and the eigenmodes, including the $Γ$-correlator of the affine force-field, which is a key ingredient of lattice-dynamic calculations of viscoelasticity. We show that the results converge well to the solution obtained by direct diagonalization (DD) of the Hessian (dynamical) matrix. As is well known, the DD approach has prohibitively high computational requirements for systems with $N=10^4$ atoms or larger. Instead, the KPM approach developed here allows one to scale up lattice dynamic calculations of real materials up to $10^6$ atoms, with a hugely more favorable (linear) scaling of computation time and memory consumption with $N$.

The variations in cost estimates depending upon techniques, and with and without inflation, are compared.
The Role of Literal Features During Processing of Novel Verbal Metaphors

description: When a word is used metaphorically (for example “walrus” in the sentence “The president is a walrus”), some features of that word's meaning (“very fat,” “slow-moving”) are carried across to the metaphoric interpretation while other features (“has large tusks,” “lives near the north pole”) are not. What happens to these features that relate only to the literal meaning during processing of novel metaphors? In four experiments, the present study examined the role of the feature of physical containment during processing of verbs of physical containment. That feature is used metaphorically to signify difficulty, such as “fenced in” in the sentence “the journalist's opinion was fenced in after the change in regime.” Results of a lexical decision task showed that video clips displaying a ball being trapped by a box facilitated comprehension of verbs of physical containment when the words were presented in isolation. However, when the verbs were embedded in sentences that rendered their interpretation metaphorical in a novel way, no such facilitation was found, as evidenced by two eye-tracking reading studies. We interpret this as suggesting that features that are critical for understanding the encoded meaning of verbs but are not part of the novel metaphoric interpretation are ignored during the construction of metaphorical meaning. Results and limitations of the paradigm are discussed in relation to previous findings in the literature both on metaphor comprehension and on the interaction between language comprehension and the visual world.

description: Control of salinity offers an opportunity to increase agricultural production along the Red River of Texas and Oklahoma. However, absolute benefits and the distribution of those benefits are sensitive to the crop yield effect of SAR (sodium absorption ratio). The effect of SAR on crop yield is not well defined. This study estimates agricultural benefits of a chloride control project as $65 million, not considering any SAR effect and $117 million with an SAR effect. Further, distribution of benefits was reversed between the eastern and western portions of the study area.
Evidence for a long range structure in the pion emission source in Au+Au collisions at RHIC

description: The PHENIX experiment, has recently acquired $\sim$ 1 billion minimum bias Au+Au events at $\sqrt s = 200$GeV during the year-2004 run. This high statistics data set, coupled with a state-of-the-art analysis technique, allows for the extraction of 3D emission sources for various particle types. These 3D sources lend fresh insight into the nature of a long-range source previously reported by PHENIX. The new results indicate an anisotropic pion emission source in the pair c.m. having an extended space-time extent oriented in the outward direction. The two-proton emission source from the same data set is essentially isotropic the pair c.m. frame. These results provide a "window" for viewing the evolution dynamics of the high energy density nuclear matter created at RHIC.

description: Simulation is used to examine impacts of land expansion strategies and self-imposed borrowing limits upon growth and survival odds of a dryland wheat farm over a 15-year period. Compared to share-rent expansion, purchasing land shows only marginally great growth at best, with substantially higher odds of firm failure. A tradeoff of enhanced survival at the expense of reduced growth results from more conservative borrowing for land. The marginal value of liquidity (for assisting survival) is relatively high at lower levels of credit reserves.

description: In topology optimization, the treatment of stress constraints for very large scale problems has so far not been tractable due to the failure of robust agglomeration methods, i.e. their inability to accurately handle the locality of the stress constraints. This paper presents a three-dimensional design methodology that alleviates this shortcoming using both deterministic and robust problem formulations. The robust formulation, based on the three-field density projection approach, is extended to handle manufacturing uncertainty in three-dimensional stress-constrained problems. Several numerical examples are solved and further post-processed with body-fitted meshes using commercial software. The numerical investigations demonstrate that: (1) the employed solution approach based on the augmented Lagrangian method is able to handle large problems, with hundreds of millions of stress constraints; (2) if appropriate interpolation parameters are adopted, voxel-based (fixed grid) models can be used to compute von Mises stresses with excellent accuracy; and (3) in order to ensure manufacturing tolerance in three-dimensional stress-constrained topology optimization, a combination of double filtering and more than three realizations may be required.

description: This paper deals with a nonparametric shape respecting estimation method for U-shaped or unimodal functions. A general upper bound for the nonasymptotic L_1-risk of the estimator is given. The method is applied to the shape respecting estimation of several classical functions, among them typical intensity functions encountered in the reliability field. In each case, we derive from our upper bound the spatially adaptive property of our estimator with respect to the L_1-metric: it approximately behaves as the best variable binwidth histogram of the function under estimation.

description: The study presented in this paper is part of the ACCELERATES (Assessing Climate Change Effects on Land Use and Ecosystems from Regional Analysis to The European Scale) project whose main goal is the construction of integrated predictions of future land use in Europe. The scenarios constructed in the project include estimates not only due to changes in the climate baseline, but also estimates due to possible future changes in socio-economics. The overall aim of the ACCELERATES was to assess the vulnerability of European agroecosystems based on economic and environmental considerations in term of both their sensitivity and capacity to adapt changes. The historical background, the type of economy, the policy aim and governance and importance of agriculture in the overall national economy have created large differences between Western and Central and Eastern European countries (CEECs). This paper focuses on vulnerability of the farm sector and rural economy of CEECs.

description: The no-slip boundary condition at a solid-liquid interface is at the center of our understanding of fluid mechanics. However, this condition is an assumption that cannot be derived from first principles and could, in theory, be violated. We present a review of recent experimental, numerical and theoretical investigations on the subject. The physical picture that emerges is that of a complex behavior at a liquid/solid interface, involving an interplay of many physico-chemical parameters, including wetting, shear rate, pressure, surface charge, surface roughness, impurities and dissolved gas.

description: We propose a test of the Porter hypothesis for the Dutch horticulture sector, using a stochastic production frontier analysis allowing for an inclusion of policy variables to account for the effect of environmental policy of firm performance. We find considerable heterogeneity in the way firms react to environmental policy measures. Our estimation results indicate, for example, that a 1997 voluntary agreement covering energy, nutrient and pesticides use enhances technical efficiency of vegetable and plants growers, contrary to specialised flower growers. Specialised flower growers, however, did react to the 1993 multi-year agreement on energy reduction, contrary to vegetable and plant growers. Summarising, our findings are mixed but do not seem to reject the anecdotal evidence mentioned by Porter and Van der Linde (1995b) that Dutch horticulture firms' performance increased due to increased environmental stringency.

description: The laws of quantum mechanics are often tested against the behaviour of the lightest element in the periodic table, hydrogen. One of the most striking properties of molecular hydrogen is the coupling between molecular rotational properties and nuclear spin orientations, giving rise to the spin isomers ortho- and para-hydrogen. At high pressure, as intermolecular interactions increase significantly, the free rotation of H2 molecules is increasingly hindered, and consequently a modification of the coupling between molecular rotational properties and the nuclear spin system can be anticipated. To date, high-pressure experimental methods have not been able to observe nuclear spin states at pressures approaching 100 GPa and consequently the effect of high pressure on the nuclear spin statistics could not be directly measured. Here, we present in-situ high-pressure nuclear magnetic resonance data on molecular hydrogen in its hexagonal phase I up to 123 GPa at room temperature. While our measurements confirm the presence of I=1 ortho-hydrogen at low pressures, above 70 GPa, where inter- and intramolecular distances become comparable, we observe a crossover in the nuclear spin statistics from a spin-1 quadrupolar to a spin-1/2 dipolar system, evidencing the loss of spin isomer distinction. These observations represent a unique case of a nuclear spin crossover phenomenon in quantum solids.

description: Despite much work, the connection between dwarf elliptical galaxies (dEs) and dwarf irregulars (dIs) remains unclear. Recently, we found that the surface brightness profiles (SBPs) of dIs in the near-infrared can be well fitted with a hyperbolic secant (sech) function. From sech fits, a tight relationship was derived between the absolute magnitude, central surface brightness, and 21cm line widths, which amounts to a fundamental plane for dIs. Here we examine how closely dEs fit into the dI fundamental plane using published data for 22 dEs in the Virgo cluster and the Local Group. Over a 9 mag interval in absolute magnitude the dEs fall in the plane defined by the dIs. The outstanding overlap suggests more than a casual relationship between the two classes.

description: Different types of ordering phenomena may occur during phase transitions, described within the universal framework of the Landau theory through the evolution of one, or several, symmetry-breaking order parameter h. In addition, many systems undergo phase transitions related to an electronic instability, in the absence of a symmetry-breaking and eventually described through the evolution of a totally symmetric order parameter q linearly coupled to volume change. Analyzing the coupling of a non-symmetry-breaking electronic instability, responsible for volume strain, to symmetry-breaking phenomena is of importance for many systems in nature and here we show that the symmetry-allowed qh2 coupling plays a central role. We use as case study the rubidium manganese hexacyanoferrate Prussian blue analogue, exhibiting phase transitions with hysteresis that may exceed 100 K, and based on intermetallic charge transfer (CT). During the phase transition, the intermetallic CT described through the evolution of q is coupled to cubic-tetragonal ferroelastic symmetry-breaking described through the evolution of h. In this system, the symmetry-breaking and non-symmetry breaking deformations have similar amplitudes but the large volume strain is mainly due to CT. We analyze both the ferroelastic and the CT features of the phase transition within the frame of the Landau theory, taking into account the qh2 coupling, stabilizing concomitant CT and Jahn-Teller distortion. The phase diagrams obtained with this model are in good qualitative agreement with various experimental findings and apply to diverse families of materials undergoing Mott transition, spin-crossover, neutral-ionic transition, for which isostructural electronic instability driving volume strain can couple to symmetry-breaking or not, create phase transition lines and drive cooperative phenomena.

description: The present paper extents the existing literature providing a theoretically consistent framework for measuring input-specific technical efficiency in damage control inputs within a stochastic production frontier model. The theoretical framework for modeling damage control agents is based on Fox and Weersink (1995) model specification that allows for increasing returns on damage control inputs. The empirical model accounts veterinary expenses as the damage control input and it is applied on a panel data set of sheep farms in Greece during the 1989-92 period. The results suggest that sheep farms in Greece are using inefficiently immunization and antibiotics in their flock as their average technical efficiency level was 72.82%. On the other hand, technical efficiency in conventional factors of production was found to be considerably higher on the average, 91.32%. Finally, our results indicate that farms that are technical efficient in the use of conventional inputs are also technical efficient in the use of damage control agents.
Accreting White Dwarfs among the Planetary Nebulae Most Luminous in [O III]5007 Emission
Creators: name: Soker, Noam
Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)

description: I propose that some of the most luminous planetary nebulae (PNs) are actually proto-PNs, where a companion white dwarf (WD) accretes mass at a relatively high rate from the post-asymptotic giant branch star that blew the nebula. The WD sustains a continuous nuclear burning and ionizes the nebula. The WD is luminous enough to make the dense nebula luminous in the [O III]5007 line, In young stellar populations these WD accreting systems account for a small fraction of [O III]-luminous PNs, but in old stellar populations these binaries might account for most, or even all, of the [OIII]-luminous PNs. This might explain the puzzling constant cutoff (maximum) [O III]5007 luminosity of the planetary nebula luminosity function across different galaxy types.

description: Spin glasses are the paradigm of complex systems. These materials present really slow dynamics. However, the nature of the spin glass phase in finite dimensional systems is still controversial. Different theories describing the low temperature phase have been proposed: droplet, replica symmetry breaking and chaotic pairs. We present analytical studies of critical properties of spin glasses, in particular, critical exponents at and below the phase transition, existence of a phase transition in a magnetic field, computation of the lower critical dimension (in presence/absence of a magnetic field). We also introduce some rigorous results based on the concept of metastate. Finally, we report some numerical results regarding the construction of the Aizenman-Wehr metastate, scaling of the correlation functions in the spin glass phase and existence of a phase transition in a field, confronting these results with the predictions of different theories.

description: The main objective of the paper is to trace the composition of the CAP support for Italian farms at the eve of the implementation of the CAP reform. The paper is based on three regional case studies, that represent as many farming specialisation typologies: Veneto, in the North-East, where agriculture is largely integrated in the economic system; Valle d'Aosta, in the North-West, a typical Alpine region; Puglia, in the South, where agriculture is based on Mediterranean products. The three regional cases are compared with the national average as a benchmark with regards to production specialisation, territorial disadvantages, entrepreneurial choices. It is evident that at the national level the composition of support is highly in favour of the support coming from the first pillar of the CAP. However, if the analysis is shifted to a regional level, the composition of support changes and, in some cases, it turns in favour of the second pillar support.

description: Exploding granules constitute the strongest horizontal flows on the quiet Sun and contribute to the structure of the surface horizontal velocity fields which build the large-scale organization of the discrete magnetic field. In this work we explore exploding granule expansion through the observations of the ground-based THEMIS telescope, IRIS, SDO, and the Hinode space-borne instruments, and finally with the magnetohydrodynamics simulation. We evaluate the detection and the expansion of exploding granules at several wavelengths and at various spatial and temporal resolutions. To analyze the different temporal sequences, two methods of image segmentation are applied to select the granules. The first allows us to follow individually the exploding granules observed simultaneously by THEMIS, IRIS, and SDO. The second uses long time independent sequences from THEMIS, IRIS, SDO, Hinode, and a simulation. In the first method (called manual) the segmentation isolates the cell of the granules (bright granules and intergranular parts), while in the second method (called statistical) only the bright part of the granules are isolated. The results obtained with simultaneous or distinct temporal observations using the two methods of segmentation are in good agreement. The granule area evolves linearly with an expansion velocity that decreases with the radius. A rapid decrease in the velocity expansion in the first two minutes is observed. The detection and measurement of the dynamics of the explosive granules can be performed from ground- and space-based instruments. Our work reveals the usefulness of SDO data, with low spatial resolution, to study the dynamics of the exploding granules all over the solar surface

description: This study analyzes the impact of the Mid-Term Review (MTR) on the agricultural sector in Schleswig-Holstein, a federal state in Germany. First, a very detailed farm group linear programming model is built to quantify the effects on agricultural production and farm incomes. The production adjustment to the MTR and its impact on farm profit vary significantly between individual farms. These results depend mainly on the farm type and the resource endowments of the farms. Second, the impact on structural change is examined with a farm survival model. Although the MTR clearly reduces the incomes of several farm types, it accelerates the structural change only gradually.

description: In this paper we develop an analytical framework for the estimation of the structural model parameters of an incentive contract under moral hazard with heterogeneous agents. Using micro level data on swine production contract settlements, we confirm that contract farmers are heterogenous with respect to their risk aversion and that this heterogeneity affects the principal's allocation of production inputs across farmers. Assuming that contracts are optimal, we obtain estimates of a lower and an upper bound of agents' reservation utilities. We show that farmers with higher risk aversion have lower outside opportunities and hence lower reservation utilities.
Optimal smoothing in nonparametric mixed-effect models

description: Mixed-effect models are widely used for the analysis of correlated data such as longitudinal data and repeated measures. In this article, we study an approach to the nonparametric estimation of mixed-effect models. We consider models with parametric random effects and flexible fixed effects, and employ the penalized least squares method to estimate the models. The issue to be addressed is the selection of smoothing parameters through the generalized cross-validation method, which is shown to yield optimal smoothing for both real and latent random effects. Simulation studies are conducted to investigate the empirical performance of generalized cross-validation in the context. Real-data examples are presented to demonstrate the applications of the methodology.

description: Structural chirality can induce counter-intuitive optical forces due to inherent symmetry properties. While optical forces on a single chiral particle in the Rayleigh regime have been well studied, optical forces in coupled chiral particles remain less explored. By using full-wave numerical simulations and analytical methods of source representation and coupled mode theory, we investigated the optical forces induced by a plane wave on two chiral particles coupling with each other via the evanescent near fields. We found that the induced electric and magnetic dipoles of the chiral particles have complicated couplings that give rise to dark and bright modes. The interaction force between the particles can be either attractive or repulsive, and its magnitude can be significantly enhanced by the resonance modes. The attractive force is much stronger if two particles are of opposite handedness compared with the case of same handedness. The electric dipole force and the magnetic dipole force have the same sign for two particles with the same handedness, while they are of different signs for two particles with opposite handedness. The results can lead to a better understanding of chirality-induced optical forces with potential applications in optical manipulations and chiral light-matter interactions.

description: In the first part we calculate the boundary susceptibility $χ_B$ in the open $XXZ$-chain at zero temperature and arbitrary magnetic field $h$ by Bethe ansatz. We present analytical results for the leading terms when $|h|\ll α$, where $α$ is a known scale, and a numerical solution for the entire range of fields. In the second part we calculate susceptibility profiles near the boundary at finite temperature $T$ numerically by using the density-matrix renormalization group for transfer matrices and analytically for $T\ll 1$ by field theoretical methods. Finally we compare $χ_B$ at finite temperature with a low-temperature asymptotics which we obtain by combining our Bethe ansatz result with recent predictions from bosonization.

Success factors that helped First Nation students complete their university degrees

Publisher: name: University of British Columbia

description: This study explored those factors that contributed to the graduation rate of First Nations students who successfully completed an undergraduate degree. The purpose of this study was fourfold: (1) to create a profile of First Nations students who graduated from a university; (2) map out those experiences that either facilitated, or hindered the student's educational endeavors; (3) explore those variables, that defined how students overcame hindering factors; (4) to develop a grounded theory representative of students' educational achievements. The research method involved in-depth interviews with seven First Nations students, who received an undergraduate degree from a university, and were either from Vancouver, or were long-term residents of British Columbia. The students described: (a) their educational experiences, that contributed to the completion of their degrees; (b) factors that either facilitated, or hindered with their educational goals; (c) how students maneuvered to overcome obstacles, that were not helpful; and (d) those factors, that played a role in students' desire in completing their degree. Basic techniques, and procedures based on the grounded theory methodology conveyed a variety of factors that subsequently formed five major core categories leading to the students' graduation rates. Analysis of content, and verification of the categories were defined through coding techniques, and constant comparison methods that were grounded in the data. The results indicated that the students' success rates were the result of the following factors: Personal factors, sources of support, institutional factors, geographical factors, and overcoming barriers to success. The educational experiences that the students shared supports the notion that the transitional stage they must endeavor is a dynamic process, and reflects various dimensions. These dimensions were linked in a conceptual model that reflected the basic process of becoming whole, and maintaining balance within an environment that is sometimes conflicting, and contrary to the students' cultural values, and beliefs.
Convective magneto-rotational instabilities in accretion disks

description: We present a study of instabilities occuring in thick magnetized accretion disks. We calculate the growth rates of these instabilities and characterise precisely the contribution of the magneto-rotational and the convective mechanism. All our calculations are performed in radially stratified disks in the cylindrical limit. The numerical calculations are performed using the appropriate local dispersion equation solver discussed in Blokland et al. (2005). A comparison with recent results by Narayan et al. (2002) shows excellent agreement with their approximate growth rates only if the disks are weakly magnetized. However, for disks close to equipartition, the dispersion equation from Narayan et al. (2002) loses its validity. Our calculations allow for a quantitative determination of the increase of the growth rate due to the magneto-rotational mechanism. We find that the increase of the growth rate for long wavelength convective modes caused by this mechanism is almost neglible. On the other hand, the growth rate of short wavelength instabilities can be significantly increased by this mechanism, reaching values up to 60%.

description: Studies on physics identity have shown that it is one of the main factors that can predict a person's persistence in the field; therefore, studying physics identity is critical to increase diversity within the field of physics and to understand what changes can allow more women and minorities to identify with the field. In this study, we investigate informal physics programs as spaces for physics identity exploration. These programs provide unique conditions under which to study physics identity development along with other identities. Informal physics spaces allow for voluntary engagement, as well as elements of agency and autonomy within the exploration of physics. Thus these spaces allow an identity to form outside of the constraints traditionally found in academic settings. In this work, we operationalized the Community of Practice (CoP) framework to study the development of physics identities within university students who facilitate informal physics programs. We present the stories from two physics graduate students out of our sample to provide a context for testing the feasibility of the extended framework and to identify how experiences within an informal physics program can shape physics identity development. This paper presents the operationalized constructs within the Community of Practice framework, how these constructs are applied to the narrated experiences of our participants, and highlights how we can use this framework to understand the nuances of physics identity development as well as the factors that can influence that development.
