description: Lattice Hamiltonians with on-site interaction $W$ have W=0 solutions, that is, many-body {\em singlet} eigenstates without double occupation. In particular, W=0 pairs give a clue to understand the pairing force in repulsive Hubbard models. These eigenstates are found in systems with high enough symmetry, like the square, hexagonal or triangular lattices. By a general theorem, we propose a systematic way to construct all the W=0 pairs of a given Hamiltonian. We also introduce a canonical transformation to calculate the effective interaction between the particles of such pairs. In geometries appropriate for the CuO$_{2}$ planes of cuprate superconductors, armchair Carbon nanotubes or Cobalt Oxides planes, the dressed pair becomes a bound state in a physically relevant range of parameters. We also show that W=0 pairs quantize the magnetic flux like superconducting pairs do. The pairing mechanism breaks down in the presence of strong distortions. The W=0 pairs are also the building blocks for the antiferromagnetic ground state of the half-filled Hubbard model at weak coupling. Our analytical results for the $4\times 4$ Hubbard square lattice, compared to available numerical data, demonstrate that the method, besides providing intuitive grasp on pairing, also has quantitative predictive power. We also consider including phonon effects in this scenario. Preliminary calculations with small clusters indicate that vector phonons hinder pairing while half-breathing modes are synergic with the W=0 pairing mechanism both at weak coupling and in the polaronic regime.

description: This paper revisits the inequality-growth relationship accounting for sectoral differences and focusing on US counties. For 8 two-digit industries of the NAICS classification, we estimated a conditional growth model where employment growth depends on regional income inequality and a number of control variables. Spatial econometrics techniques are used to account for spatial dependence. Results indicate that there is no association between employment growth and family income inequality for the Agriculture, Forestry, Fishing and Hunting sector and the Real Estate, Rental and Leasing sector. However, income inequality consistently shows a negative impact on employment growth in the construction sector, and results are mixed for other sectors such as: Manufacturing; Retail Trade; Professional Scientific and Technical Services; Accommodation and Food Services; Educational Services. In several sectors, mixed results were obtained when differentiation is made between urban and rural samples.
Potential Harmonics Expansion Method for Trapped Interacting Bosons : Inclusion of Two-Body Correlation

Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We study a system of $A$ identical interacting bosons trapped by an external field by solving ab initio the many-body Schroedinger equation. A complete solution by using, for example, the traditional hyperspherical harmonics (HH) basis develops serious problems due to the large degeneracy of HH basis, symmetrization of the wave function, calculation of the matrix elements, etc. for large $A$. Instead of the HH basis, here we use the "potential harmonics" (PH) basis, which is a subset of HH basis. We assume that the contribution to the orbital and grand orbital [in $3(A-1)$-dimensional space of the reduced motion] quantum numbers comes only from the interacting pair. This implies inclusion of two-body correlations only and disregard of all higher-body correlations. Such an assumption is ideally suited for the Bose-Einstein condensate (BEC), which is extremely dilute. Unlike the $(3A-4)$ hyperspherical variables in HH basis, the PH basis involves only three {\it{active}} variables. It drastically reduces the number of coupled equations and calculation of the potential matrix becomes tremendously simplified, as it involves integrals over only three variables for any $A$. One can easily incorporate realistic atom-atom interactions in a straight forward manner. We study the ground and excited state properties of the condensate for both attractive and repulsive interactions for various particle number.

description: This paper analyses relevant determinants for the probability to initiate a dispute on policy measures under the World Trade Organization (WTO) dispute settlement system. The empirical analysis focuses on agro-food-related disputes to provide sector-specific information on the driving factors in dispute settlement, and complements and extends previous studies by incorporating new potential determinants. The focus is shifted to bilaterally dependent characteristics to take care of trade related and power-based relationships between Members. Contrary to recent analyses of overall trade disputes, the results show that some determinants such as export value and monetary means are not statistically significant. However, the import dependency from the defendant party could be identified as a relevant determinant in disputes.

description: This article presents new gradient estimates for positive solutions to the nonlinear fast diffusion equation on smooth metric measure spaces, involving the $f$-Laplacian. The gradient estimates of interest are mainly of Hamilton-Souplet-Zhang or elliptic type and are proved using different set of methods and techniques. Various implications notably to parabolic Liouville type results and characterisation of ancient solutions are given. The problem is considered in the general setting where the metric and potential evolve under a super flow involving the Bakry-Émery $m$-Ricci curvature tensor. The remarkable interplay between geometry, nonlinearity, and evolution -- and their intricate roles in the estimates and the maximum exponent range of fast diffusion -- is at the core of the investigation.

description: This paper studies the regional distribution of the benefits from trade in Mexico after NAFTA. Specifically, we ask whether or not NAFTA has increased the concentration of economic activity in Mexico. Unlike previous work which uses state-level data, we identify the effect of NAFTA on economic activity at the municipal level allowing us to observe detailed growth patterns across space. Further, to explicitly identify the effect of the trade agreement, we compare results for growth in traded and non-traded sectors. Given the spatial nature of these data, we make explicit use of spatial econometrics methods. We find that NAFTA caused the wealthy regions nearest to the border to grow faster than others, increasing regional disparity. Second, we find that larger municipalities experienced greater per-capita economic benefits from NAFTA. This effect is particularly noticeable in the north. Somewhat surprisingly, we find that regions with a less literate workforce and worse infrastructure grew faster than other areas after the trade agreement, decreasing regional disparity. We notice these redistributive effects occur primarily in the non-traded sectors.

description: In the model of Chain Inflation, a sequential chain of coupled scalar fields drives inflation. We consider a multidimensional potential with a large number of bowls, or local minima, separated by energy barriers: inflation takes place as the system tunnels from the highest energy bowl to another bowl of lower energy, and so on until it reaches the zero energy ground state. Such a scenario can be motivated by the many vacua in the stringy landscape, and our model can apply to other multidimensional potentials. The ''graceful exit'' problem of Old Inflation is resolved since reheating is easily achieved at each stage. Coupling between the fields is crucial to the scenario. The model is quite generic and succeeds for natural couplings and parameters. Chain inflation succeeds for a wide variety of energy scales -- for potentials ranging from 10MeV scale inflation to $10^{16}$ GeV scale inflation.

description: We present a catalog of 246 radio sources found in the central 1 degree of the COSMOS field at 1.4GHz. The VLA pilot project data have a resolution of 1.9"x1.6" and an rms noise limit of ~25-100uJy/beam covering 0.837 sqrdeg. About 20 radio sources are clearly extended and most of them appear to be double-lobed radio galaxies. We find evidence for a cluster of 7 radio sources with an extent of ~10' southeast of the COSMOS field center. This VLA pilot project was undertaken to demonstrate the feasibility of wide-field mosaicking at 2'' resolution at 1.4GHz using the VLA in its A array configuration. The 7-point mosaic data was used to develop the techniques necessary for reduction and analysis. These data will provide the initial astrometric frame for the optical (ground- and space-based) data of the COSMOS 2 sqrdeg survey. In addition, it demonstrates the feasibility of obtaining deep (rms ~ few uJy) radio imaging of this field at 1.4GHz, since the brightest radio emission peak detected within the area covered has a flux density of 13mJy/beam and no strong side-lobes from sources surrounding the COSMOS field were detected. Comparison of the number counts to other deep radio surveys shows that the COSMOS field is a representative deep field in the radio domain.

description: Seventy-two grids of stellar evolutionary tracks, along with the capability to generate isochrones and luminosity/color functions from them, are presented in this investigation. Sixty of them extend (and encompass) the sets of models reported by VandenBerg et al. (2000, ApJ, 532, 430) for 17 [Fe/H] values from -2.31 to -0.30 and alpha-element abundances corresponding to [alpha/Fe] = 0.0, 0.3, and 0.6 (at each iron abundance) to the solar metallicity and to sufficiently high masses (up to ~2.2 solar masses) that isochrones may be computed for ages as low as 1 Gyr. The remaining grids contain tracks for masses from 0.4 to 4.0 solar masses and 12 [Fe/H] values between -0.60 and +0.49 (assuming solar metal-to-hydrogen number abundance ratios): in this case, isochrones may be calculated down to ~0.2 Gyr. The extent of convective core overshooting has been modelled using a parameterized version of the Roxburgh (1989, A&A, 211, 361) criterion, in which the value of the free parameter at a given mass and its dependence on mass have been determined from analyses of binary star data and observed color-magnitude diagrams for several open clusters. Because the calculations reported herein satisfy many empirical constraints, they should provide useful probes into the properties of both simple and complex stellar populations.

Localization of peripheral reactions and sensitivity to the imaginary potential

description: The aim of the present study is to make for the first time in the literature a systematic and quantitative assessment of the evaluation of the imaginary part of the optical potential calculated within the folding model and its consequences on the localization of surface reactions. Comparing theoretical and experimental reaction cross sections, for some light projectiles on a $^9$Be target, it has recently been shown that a single-folded s.f. (light-) nucleus-$^9$Be imaginary optical potential is more accurate than a double-folded d.f. optical potential. Within the eikonal formalism for the cross sections and phase shifts, the single-folded potential was obtained using a n-$^9$Be phenomenological optical potential and microscopic projectile densities. This paper is a follow-up in which we systematically study a series of different light and medium-mass projectile induced reactions on $^9$Be. Our results confirm that the s.f. cross sections are larger than the d.f. cross sections and the effect increases with the projectile mass. Furthermore the strong absorption radius parameter extracted from the $S$ matrices calculated with the s.f. has a stable value $r_s$ =1.3 - 1.4 fm for all projectile masses in the range of incident energies 40-100AMeV. This indicates that a clear geometrical separation can be made between the region of surface reactions, the region of strong absorption into other channels and the region of weak nuclear interaction. The d.f. results are instead much scattered and the separation between surface reactions and other channels does not seem to be consistent. Excellent agreement with recent experimental results confirms the validity of our approach.

Collider signals of gravitino dark matter in bilinearly broken R-parity

description: In models with gauge mediated supersymmetry breaking the gravitino is the lightest supersymmetric particle. If R-parity is violated the gravitino decays, but with a half-live far exceeding the age of the universe and thus is, in principle, a candidate for the dark matter. We consider the decays of the next-to-lightest supersymmetric particle, assumed to be the neutralino. We show that in models where the breaking of R-parity is bilinear, the condition that R-parity violation explains correctly the measured neutrino masses fixes the branching ratio of the decay ${\tilde χ}^0_1 \to {\tilde G}γ$ in the range $10^{-3}-10^{-2}$, if the gravitino mass is in the range required to solve the dark matter problem, i.e. of the order (few) 100 eV. This scenario is therefore directly testable at the next generation of colliders.

description: The objective of this paper is to compare the accuracy of crop insurance rating methods based on historical liability and indemnity data (similar to the procedure currently used by the Risk Management Agency) and “yield distribution” approaches. Estimated rates are compared to “true” rates using empirically-grounded simulation procedures that take into account common data availability constraints. Simulation results suggest that farm and county level rate estimates using the “yield distribution” approach are significantly more accurate than those based on historical indemnity and liability records.
Degree of fixation of amine copper solutions in Scots pine (Pinus sylvestris)
Creators: name: Lucas, Nolwenn A.
Publisher: name: University of British Columbia
Year: 2009

description: Amines are solvents used in copper based wood preservatives. Understanding their influence on chemical fixation in wood is crucial for improvements to be made to the fixation of copper. In this study, Scots pine sapwood blocks were treated with monoethanolamine copper and ethylenediamine copper solutions. The influence of chemical factors, such as copper concentration and amine to copper mole ratio in the treating solution, and the physical factor temperature, were investigated. Chemical analysis of treated wood showed that monoethanolamine and ethylendiamine have different influences on the fixation chemistry of copper. As well, copper concentration and amine to copper ratio are directly related to copper retention and the amine to copper mole ratios in treated wood. The minimum wood preservative retention required by the American Wood Preservers' Association (AWPA) and Canadian Standard Association (CSA) is met with low solution concentration (0.5%) treatment. This exploratory work suggests that there is a 1:1 mole ratio of amine to copper in both monoethanolamine copper and ethylenediamine copper treated wood after leaching. Furthermore it implies that an amine-copper-wood complex is primarily formed during fixation and is supported by further spectroscopic analysis. However, the formation of copper precipitate, unbound to amine, may be produced at high solution concentrations, and at temperatures above 60°C. The copper leaching resistance can be improved from one week at ambient temperature to one hour at temperature above 60°C. In general, spectroscopic analysis showed that there are no significant changes on the spectra as the temperature is increased, nor for increased duration of post-treatment time at any temperature. Further analysis demonstrated that heating may not produce a large amount of copper(I) species (< 1%), however, extended exposure to X-rays during analysis promoted the reduction of copper(II). This study also suggests that an ammonia/monoethanolamine mixture in copper based preservatives has minor effects on copper fixation. Amine-copper-wood compound formation is preferred, but some copper(II) carbonate precipitate may form during ammonia evaporation. The addition of ammonia to monoethanolamine copper solution noticeably improved the leaching resistance of copper.

description: The presence of task constraints imposes a significant challenge to motion planning. Despite all recent advancements, existing algorithms are still computationally expensive for most planning problems. In this paper, we present Constrained Motion Planning Networks (CoMPNet), the first neural planner for multimodal kinematic constraints. Our approach comprises the following components: i) constraint and environment perception encoders; ii) neural robot configuration generator that outputs configurations on/near the constraint manifold(s), and iii) a bidirectional planning algorithm that takes the generated configurations to create a feasible robot motion trajectory. We show that CoMPNet solves practical motion planning tasks involving both unconstrained and constrained problems. Furthermore, it generalizes to new unseen locations of the objects, i.e., not seen during training, in the given environments with high success rates. When compared to the state-of-the-art constrained motion planning algorithms, CoMPNet outperforms by order of magnitude improvement in computational speed with a significantly lower variance.

Results indicated that FW and RW grapefruit (and FW and RW oranges) are not substitutes; however, RW tangerine is a substitute of FW tangerines. In addition, promoting FW grapefruit would not influence the demand for RW grapefruit and vice versa. Promoting FW oranges (or FW tangerines) would decrease the demand for RW oranges (or RW tangerines) and vice versa.

description: Attracting manufacturing investment is a frequently used rural development policy. Previous research in the location literature has informed policymakers which factors are most important for attracting new firm investment. Far less is known about the interaction of birth and death of establishments. A conceptual model of county-level investment in the U.S. manufacturing sector is developed from location theory and subsequent literature. Specifically, we test the relative importance of location factors influencing firm investment, and if these factors influence firm birth and death differently. Local factors include agglomeration due to localization, urbanization, and internal economies, market structure, labor quality, availability, and cost, market conditions, , infrastructure, and fiscal policy. This study covers the time period 2000 to 2004 for U.S. counties in the lower 48 states. Counts of establishments are from the U.S. Census Bureau’s Dynamic Firm Data Series, which links establishments across space and time. Negative binomial models containing spatially lagged endogenous variables are estimated in a regional adjustment framework to show how ceteris paribus changes in location factors affect the conditional number of establishment births and deaths in a county.

Nuclear shadowing in deep inelastic scattering on nuclei at very small x

description: Nuclear shadowing corrections to the structure functions of deep inelastic scattering on intermediate-mass nuclei are calculated at very small values of Bjorken x and small values of Q^2 (Q^2<5 Gev^2). The two-component approach developed in previous works of authors for a description of the nucleon structure functions of deep inelastic scattering is used. It is shown that the hard component of the nucleon structure functions that arises, in terms of the colour dipole model, from qq-pairs with a high transverse momentum, is almost not shadowed. It is shown that a change of the slope of the shadowing curve with a decrease of x depends, at small values of x, on the relative contribution of the hard component to the nucleon structure function (this contribution is a function of x and Q^2) and on a size of gluon saturation effects. It is shown that an accounting for saturation effects becomes essential for predictions of shadowing at x<10^-4, depending on a value of Q^2. Results of numerical calculations of nuclear shadowing for several nuclei are compared with available data of the E665 and the NMC collaborations.

description: This article discusses the literature on children in research, pupil participation and the voice of the child. The need for individual experience and children’s voice in research is explored, with the focus placed on children with dyspraxia in UK schools. The article addresses previous literature in the area which shows that teachers’ knowledge and understanding of the disorder is generally poor, such that these children remain an ‘educational underclass’. It is suggested that this can have some very significant outcomes for these children, such as low self-esteem and confidence, increased delinquency and increased unemployment. This paper argues that by gaining more knowledge and understanding by listening to the voices and lived experiences of children with dyspraxia, teachers will be better placed to provide an educational environment that is enriching and inclusive for all children, one in which those with dyspraxia will be actively able to participate and no longer remain an educational underclass.

Faith Schools

description: Currently over a third of schools in Britain are faith schools, yet their place within the British education system remains a hotly contested issue, with advocates and opponents exchanging charge and counter-charge. With the current debate sparked by the Government’s wish to establish more faith schools it is timely to explore some of the controversial issues involved. This article explores social division, intolerance and indoctrination as objections to faith schools and evaluates whether faith schools are educationally defensible.

Engagement

description: While partnerships, in England, between schools and their communities are encouraged, ‘authentic’ engagement in these partnerships is constrained by a number of factors. This article explores some of these factors and puts forward some suggestions as to how a community-orientated approach, operating through Place-Based Education, could impact positively on the educational environment and wider issues of regeneration.

description: There is widespread recognition that forestry carbon credits can reduce the net emissions of carbon into the atmosphere. Designing systems to sequester carbon, however, has proven difficult due to a number of efficiency issues, including leakage. Leakage occurs when policy makers develop carbon projects in specific places which protect some parcels of land, but leave other parcels of land unprotected. This analysis uses a newly developed model of global land use change from an established forestry and land use model, described in Sohngen et al. (1999); Sohngen and Mendelsohn (2003); and Kindermann et al. (2008). To assess leakage we estimate carbon under storage under one scenario where the world is awarded carbon credits and another where tropical developing nations are awarded the credits. We focus our results on several regions, namely Brazil, the rest of South America, Sub-Saharan Africa and Southeast Asia. Carbon prices are assumed to be constant, and range from US$0 tC to US$900 tC. The model adjusts global land uses to these specific policies, and leakage is assessed by comparing carbon gains within the project areas to net global changes in carbon. A number of policy relevant results emerge. First, the estimates indicate that leakage ranges from 2% to more than 14%. Second, as carbon credits increase, leakage decreases across the world.

A Self Consistent Field Formulation of Excited State Mean Field Theory

description: We show that, as in Hartree Fock theory, the orbitals for excited state mean field theory can be optimized via a self-consistent one-electron equation in which electron-electron repulsion is accounted for through mean field operators. In addition to showing that this excited state ansatz is sufficiently close to a mean field product state to admit a one-electron formulation, this approach brings the orbital optimization speed to within roughly a factor of two of ground state mean field theory. The approach parallels Hartree Fock theory in multiple ways, including the presence of a commutator condition, a one-electron mean-field working equation, and acceleration via direct inversion in the iterative subspace. When combined with a configuration interaction singles Davidson solver for the excitation coefficients, the self consistent field formulation dramatically reduces the cost of the theory compared to previous approaches based on quasi-Newton descent.

Group analysis of structure equations for stars in radiative and convective equilibrium

description: It is proposed to use the Lie group theory of symmetries of differential equations to investigate the system of equations describing a static star in a radiative and convective equilibrium. It is shown that the action of an admissible group induces a certain algebraic structure in the set of all solutions, which can be used to find a family of new solutions. We have demonstrated that, in the most general case, the equations admit an infinite parameter group of quasi-homologous transformations. We have found invariants of the symmetries group which correspond to the fundamental relations describing a physical characteristic of the stars such as the Hertzsprung-Russell diagram or the mass-luminosity relation. In this way we can suggest that group invariants have not only purely mathematical sense, but their forms are closely associated with the basic empirical relations.

description: In this article the authors present the results of a small-scale quantitative research project examining the assumption that there is a direct causal link between the classification of a student teacher’s first degree and their ability to teach. Evidence presented in the article supports the hypothesis that the assumption is incorrect. There appears to be no correlation, relationship or link between the classification of a student teacher’s first degree and their ability to teach. The article examines what appears to be driving current policy rhetoric in this area and questions the extent to which such rhetoric may lead to a misallocation of limited resources within Initial Teacher Education.
Modelling Planck-scale Lorentz violation via analogue models

description: Astrophysical tests of Planck-suppressed Lorentz violations had been extensively studied in recent years and very stringent constraints have been obtained within the framework of effective field theory. There are however still some unresolved theoretical issues, in particular regarding the so called "naturalness problem" - which arises when postulating that Planck-suppressed Lorentz violations arise only from operators with mass dimension greater than four in the Lagrangian. In the work presented here we shall try to address this problem by looking at a condensed-matter analogue of the Lorentz violations considered in quantum gravity phenomenology. Specifically, we investigate the class of two-component BECs subject to laser-induced transitions between the two components, and we show that this model is an example for Lorentz invariance violation due to ultraviolet physics. We shall show that such a model can be considered to be an explicit example high-energy Lorentz violations where the ``naturalness problem'' does not arise.

description: We present an XMM-Newton observation of the classical T Tauri star BP Tau. In the XMM-Newton RGS spectrum the O {\sc vii} triplet is clearly detected with a very weak forbidden line indicating high plasma densities and/or a high UV flux environment. At the same time concurrent UV data point to a small hot spot filling factor suggesting an accretion funnel shock as the site of the X-ray and UV emission. Together with the X-ray data on TW Hya these new observations suggest such funnels to be a general feature in classical T Tauri stars.

A recalibration of optical photometry: Tycho-2, Strömgren, and Johnson systems

Year: 2005

description: I use HST spectrophotometry to analyze the calibration of 3 optical photometry systems: Tycho-2 B_T V_T, Strömgren u v b y, and Johnson U B V. For Tycho-2, I revisit the analysis of Maíz Apellániz (2005) to include the new recalibration of grating/aperture corrections, vignetting, and charge transfer inefficiency effects produced by the STIS group and to consider the consequences of both random and systematic uncertainties. The new results reaffirm the good quality of both the Tycho-2 photometry and the HST spectrophotometry, but yield a slightly different value for ZP_B_T-V_T. For the Strömgren v, b, and y and the Johnson B and V filters I find that the published sensitivity curves are consistent with the available photometry and spectrophotometry and I derive new values for the associated ZP_b-y, ZP_m_1, and ZP_B-V. The situation is different for the Strömgren u and the Johnson U filters. There I find that the published sensitivity curves yield results that are inconsistent with the available photometry and spectrophotometry, likely caused by an incorrect treatment of atmospheric effects in the short-wavelength end. I reanalyze the data to produce new average sensitivity curves for those two filters and new values for ZP_c_1 and ZP_U-B. The new computation of synthetic U-B and B-V colors uses a single B sensitivity curve, which eliminates the previous unphysical existence of two different definitions. Finally, I find that if one uses values from the literature where uncertainties are not given, reasonable estimates for these are 1-2% for Strömgren b-y, m_1, and c_1 and 2-3% for Johnson B-V and U-B. The use of the results in this article should lead to a significant reduction of systematic errors when comparing synthetic photometry models with real colors and indices.
