description: Phase separation of saturated micellar network, as a result of cross-linking of branched micelles is established in mixed solutions of the anionic surfactant sodium laurylethersulfate (SLES) and the zwitterionic cocamidopropyl betaine (CAPB) in the presence of divalent counterions: Ca2+, Zn2+ and Mg2+. The saturated network appears in the form of droplets, which are heavier than water and sediment at the bottom of the vessel. In the case of Mg2+, the sedimented drops coalesce and form a separate multiconnected micellar phase - a supergiant surfactant micelle. For this phase, the rheological flow curves show Newtonian and shear-thinning regions. The appearance/disappearance of the Newtonian region marks the onset of formation of saturated network. The addition of small organic molecules (fragrances) to the multiconnected micellar phase leads to an almost spontaneous formation of oil-in-water nanoemulsion. The nanoemulsification capacity of the multiconnected micellar phase decreases with the rise of the volume of the oil molecule. A possible role of the network junctions in the nanoemulsification process can be anticipated. The properties of the multiconnected micellar phases could find applications in extraction and separation processes, in drug/active delivery, and for nanoemulsification at minimal energy input.

description: The Environmental Kuznets Curve (EKC) hypothesis – an inverted U-shape relation between various indicators of environmental degradation and income per capita – has become one of the ‘stylised facts’ of environmental and resource economics. This is despite considerable criticism on both theoretical and empirical grounds. Cointegration analysis can be used to test the validity of such stylised facts when the data involved contain stochastic trends. In the present paper, we use cointegration analysis to test the EKC hypothesis using a panel dataset of sulfur emissions and GDP data for 74 countries over a span of 31 years. We find that the data is stochastically trending in the time-series dimension. Given this, and interpreting the EKC as a long run equilibrium relationship, support for the hypothesis requires that an appropriate model cointegrates and that sulfur emissions are a concave function of income. Individual and panel cointegration tests cast doubt on the general applicability of the hypothesised relationship. Even when we find cointegration, many of the relationships for individual countries are not concave. The results show that the EKC is a problematic concept, at least in the case of sulfur emissions.

Quantum Melting of Charge Order due to Frustration in Two-Dimensional Quarter-Filled Systems

description: The effect of geometrical frustration in a two-dimensional 1/4-filled strongly correlated electron system is studied theoretically, motivated by layered organic molecular crystals. An extended Hubbard model on the square lattice is considered, with competing nearest neighbor Coulomb interaction, V, and that of next-nearest neighbor along one of the diagonals, V', which favor different charge ordered states. Based on exact diagonalization calculations, we find a metallic phase stabilized over a broad window at V' ~ V even for large Coulomb repulsion strengths as a result of frustrating the charge ordered states. Slightly modifying the lattice geometry relevant to the actual organic compounds does not alter the results, suggesting that this `quantum melting' of charge order is a robust feature of frustrated strongly correlated 1/4-filled systems.

description: Economic development is seen as the best way for Aboriginal communities to improve their welfare and lessen the considerable disadvantages they suffer. Unfortunately, the economics profession has shown little interest in their plight. Agricultural and resource economists have much to offer in helping to foster economic development in Aboriginal communities throughout Australia. Suggestions are made as to various ways in which our particular interests and experiences can hopefully be applied.

description: We present results from observations of SN 1979C with XMM-Newton in X-rays and in the UV, archival X-ray and HST data, and follow-up ground-based optical imaging. The XMM-Newton MOS spectrum shows two-temperature thermal plasma emission characteristics of both the forward (4.1 keV) and reverse shock (0.78 keV) with no intrinsic absorption. The long-term X-ray lightcurve of SN 1979C shows no sign of a decline over 16-23 yrs after its outburst. The high X-ray luminosity (8 x 10^38 ergs/s) is caused by the interaction of the shock with dense circumstellar matter, likely deposited by a strong stellar wind from the progenitor with a high mass-loss rate of 1.5 x 10^-4 M_sun/yr. The X-ray data support a strongly decelerated shock and show a mass-loss rate history which is consistent with a constant progenitor mass-loss rate and wind velocity over the past >16,000 yrs in the evolution of the progenitor. We find a CSM density profile of rho_CSM \propto r^-s with index s<1.7 and high CSM densities (>10^4 cm^-3) out to large radii from the site of the explosion (> 4 x 10^17 cm). Using XMM-Newton Optical Monitor data we further detect optical/UV emission from SN 1979C, with B, U, and UVW1-band lum. of 5,7, and 9 x 10^36 ergs/s. The young stellar cluster in the vicinity of the SN, as imaged by the HST and follow-up ground-based optical imaging, can only provide a fraction of the total observed flux, so that a significant contribution to the output likely arises from the strong interaction of SN 1979C with dense CSM.

description: Trade creation in agricultural products is defined as a statistically significant positive break in the trend function of the growth in exports and imports between member countries. The present study attempts to determine the time of any break in the trend of real exports and imports between the Canada–USA Free Trade Agreement (CUSTA) and the North American Free Trade Agreement (NAFTA) member countries for the years 1980:I through 1999:II, and document the scale of the phenomenon. The present study finds trade creation only occurs in USA agricultural exports to Canada because of CUSTA. The results confirm the theory that the regionalism of NAFTA did not lead to regionalisation or an increasing share of intraregional international trade.

description: The efficiency and equity effects of economic policies affecting the quarter of Australians who live in rural and regional Australia (RARA) are reviewed. For the most part it is argued that economy-wide policies, rather than region or industry specific policies, are appropriate. Progressive income taxation, means-tested social security payments and government funded education, health and other services directly and efficiently redistribute to support equity. Subsidies for particular industries in RARA, such as dairy, and input subsidies targeted at RARA, such as community service obligations, misallocate resources and are ineffective in meeting equity goals. Better property rights and procedures for allocating most natural resources, especially water, are necessary.

description: The scaling functions $f(ψ')$ and $F(y)$ from the $ψ'$- and $y$-scaling analyses of inclusive electron scattering from nuclei are explored within the coherent density fluctuation model (CDFM). In addition to the CDFM formulation in which the local density distribution is used, we introduce a new equivalent formulation of the CDFM based on the one-body nucleon momentum distribution (NMD). Special attention is paid to the different ways in which the excitation energy of the residual system is taken into account in $y$- and $ψ'$-scaling. Both functions, $f(ψ')$ and $F(y)$, are calculated using different NMD's and are compared with the experimental data for a wide range of nuclei. The good description of the data for $y < 0$ and $ψ' < 0$ (including $ψ'< -1$) makes it possible to show the sensitivity of the calculated scaling functions to the peculiarities of the NMD's in different regions of momenta. It is concluded that the existing data on the $ψ'$- and $y$-scaling are informative for the NMD's at momenta not larger than $2.0 ÷2.5$ fm$^{-1}$. The CDFM allows us to study simultaneously on the same footing the role of both basic quantities, the momentum and density distributions, for the description of scaling and superscaling phenomena in nuclei.

description: To explore the potential of field-effect transistors (FETs) based on monolayers of the two-dimensional semiconducting channel(SC) for spintronics, the two most important issues are to ensure the formation of variable low resistive tunnel ferromagnetic contacts(FC), and to preserve intrinsic properties of the SC during fabrication. Large Schottky barriers lead to the formation of high resistive contacts and methods adopted to control the barriers often alter the intrinsic properties of the SC. This work aims at addressing both issues in fully encapsulated monolayer WSe$_2$ FETs by using bi-layer h-BN as a tunnel barrier at the FC/SC interface. We investigate the electrical transport in monolayer WSe$_2$ FETs with current-in-plane geometry that yields hole mobilities $\sim$ 38.3 $cm^{2}V^{-1}s^{-1}$ at 240 K and On/Off ratios of the order of 10$^7$, limited by the contact regions. We have achieved ultralow effective Schottky barrier ($\sim$ 5.34 meV) with encapsulated tunneling device as opposed to a non-encapsulated device in which the barrier heights are considerably higher. These observations provide an insight into the electrical behavior of the FC/h-BN/SC/h-BN heterostructures and such control over the barrier heights opens up the possibilities for WSe$_2$-based spintronic devices.

description: This paper presents an analysis of requirements in international agri-food trade by applying new data collected in the EU project “NTM impact”. For the analysis, an index of regulatory heterogeneity in trade is developed so as to combine binary, ordered and quantitative information contents of different types of requirements. The results of the index analysis shed light on which requirements differ between pairs of trade partner countries and show which products are regulated more than others. In a second step, the results will be set into the context of trade indicators such as trade flows for example. The analysis of differences of requirements between countries can provide useful insights for policy-makers when deciding on convergence, harmonisation or equivalence of requirements or when solving market access issues due to regulatory heterogeneity.

description: Das Jahr 2011 hatte zahlreiche einschneidende globale Ereignisse vorzuweisen. Die Medienberichterstattung, zumal im Zeitalter allgegenwärtiger, dezentraler und mobiler Medien, war erfüllt von bedrohlichen Nachrichten. Angefangen beim Dioxinskandal ging die Berichterstattung über den Arabischen Frühling und Fukushima hin zur EHEC-Krise. Lebensmittelskandale geschehen in wiederkehrenden Abständen und gelangen in die Medien zumeist mit verunsichernden Berichterstattungen. Dieser Beitrag beschäftigt sich mit der EHEC-Krise und wendet ein agentenbasiertes Modell zur Analyse unterschiedlicher Informationsszenarien an. Hierbei wird insbesondere auf die Problematik der Zuständigkeiten und Kompetenzen bei einer Lebensmittelkrise im föderalen System der Bundesrepublik Deutschland eingegangen. Die Simulationen zeigen auf, dass die Bündelung von Informationen über unsichere Lebensmittel durch eine zentrale Instanz, die sachlich aufklärt, negative Effekte auf die Wohlfahrt reduzieren kann. Auch wenn das Modell eine starke Vereinfachung der Realität aufweist, so lassen sich doch zentrale Prozesse gut abbilden und die Ergebnisse geben einige Hinweise auf die Ausgestaltung von effizienten Risikokommunikationsstrategien.
Redshift-Space Distortions, Pairwise Velocities and Nonlinearities

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We derive the exact relationship, including all non-linearities, between real-space and redshift-space two-point statistics through the pairwise velocity distribution function. We show using numerical simulations that the pairwise velocity PDF is strongly non-Gaussian at all scales, and explain why this is so. We caution that a commonly used ansatz to model the redshift-space power spectrum gives rise to an unphysical distribution of pairwise velocities, and show that it is in general impossible to derive the distribution from measurements of redshift-space clustering. Methods that claim to do this obtain instead something else, whose properties we derive. We provide a general derivation of the large-scale limit of the redshift-space power spectrum and show that it differs from the Kaiser formula by terms that depend on Gaussian and non-Gaussian contributions to the velocity dispersion of large-scale flows. We also show that the large-scale evolution of velocity fields is not well described by linear theory and discuss how this impacts the redshift-space power spectrum. Finally, we stress that using the monopole of the redshift-space power as an indicator of the real-space power spectrum shape can lead to systematic effects in the determination of cosmological parameters; nevertheless a simple procedure is able to recover the large-scale real-space power spectrum rather well.

description: We develop a thermodynamic framework for closed and open chemical networks applicable to non-elementary reactions that do not need to obey mass action kinetics. It only requires the knowledge of the kinetics and of the standard chemical potentials, and makes use of the topological properties of the network (conservation laws and cycles). Our approach is proven to be exact if the network results from a bigger network of elementary reactions where the fast-evolving species have been coarse grained. Our work should be particularly relevant for energetic considerations in biosystems where the characterization of the elementary dynamics is seldomly achieved.

description: The "uncertainty principle", one of the main principles of quantum physics, was proposed by the German physicist Werner Heisenberg in 1927. The uncertainty principle states that some properties of a subatomic particle, such as an electron, cannot be measured simultaneously with infinite precision. One pair that has an uncertainty relationship between them is momentum-position. First, the more uncertain the position of a subatomic particle, the more uncertain its momentum. The reverse of this relationship is also true.

description: Chain Event Graphs (CEGs) are a recent family of probabilistic graphical models - a generalisation of Bayesian Networks - providing an explicit representation of structural zeros, structural missing values and context-specific conditional independences within their graph topology. A CEG is constructed from an event tree through a sequence of transformations beginning with the colouring of the vertices of the event tree to identify one-step transition symmetries. This coloured event tree, also known as a staged tree, is the output of the learning algorithms used for this family. Surprisingly, no general algorithm has yet been devised that automatically transforms any staged tree into a CEG representation. In this paper we provide a simple iterative backward algorithm for this transformation. Additionally, we show that no information is lost from transforming a staged tree into a CEG. Finally, we demonstrate that with an optimal stopping criterion, our algorithm is more efficient than the generalisation of a special case presented in Silander and Leong (2013). We also provide Python code using this algorithm to obtain a CEG from any staged tree along with the functionality to add edges with sampling zeros.

description: It is long known that the Fokker-Planck equation with prescribed constant coefficients of diffusion and linear friction describes the ensemble average of the stochastic evolutions in velocity space of a Brownian test particle immersed in a heat bath of fixed temperature. Apparently, it is not so well known that the same partial differential equation, but now with constant coefficients which are functionals of the solution itself rather than being prescribed, describes the kinetic evolution (in the infinite particle limit) of an isolated N-particle system with certain stochastic interactions. Here we discuss in detail this recently discovered interpretation.

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.

Angesichts eines massiven Wettbewerbsdrucks werden zudem verschiedene Profilierungsmöglichkeiten für Landhandelsunternehmen herausgearbeitet und deren Beitrag zur Kundenzufriedenheit empirisch überprüft. Eine Fokusgruppen-Diskussion mit Landwirten beleuchtet die landwirtschaftlichen Sichtweise auf die aktuellen Markt- und Strukturentwicklungen sowie die Beziehungen zum und Zufriedenheit mit dem Landhandel. Explizit werden Potenziale einer Ausschaltung der Landhandelsstufe diskutiert. Anhand einer großzahligen schriftlichen Befragung von Landwirten aus Nord- und Nord-Ostdeutschland wird untersucht, welche Leistungen der Landhändler zu Kundenzufriedenheit führen und damit Potenzial für die Entwicklung von Kernkompetenzen bieten. Die Ergebnisse der multinomialen logistischen Regression zeigen, dass neben der Konditionenpolitik auch die Serviceprofilierung entscheidend für die Kundenzufriedenheit ist. Die Identifikation geschäftsbereichsübergreifender Kernkompetenzen ist angezeigt.

They are the result of the tidal interaction of the non-axisymmetric gravitational forces of the central binary with the surrounding disk and are most prominent in the inner region, where the asymmetry is most pronounced. Aims. The goal of this study is to test the feasibility of reconstructing the gas density distribution and quantifying properties of structures in the inner regions of edge-on circumbinary disks using multiple molecular line observations. Methods. The density distribution in circumbinary disks is calculated with two-dimensional hydrodynamic simulations. Subsequently, molecular line emission maps are generated with 3D radiative transfer simulations. Based on these, we investigate the observability of characteristic circumbinary structures located in the innermost region for spatially resolved and unresolved disks. Results. We find that it is possible to reconstruct the inner cavity, accretion arms and density waves from spatially resolved multi-wavelength molecular line observation of circumbinary disks seen edge-on. For the spatially unresolved observation only an estimate for the density gradient in the transition area from cavity to inner disk rim can be derived.

description: We consider the heat equation associated to Schrödinger operators acting on vector bundles on asymptotically locally Euclidean (ALE) manifolds. Novel $L^p - L^q$ decay estimates are established, allowing the Schrödinger operator to have a non-trivial $L^2$-kernel. We also prove new decay estimates for spatial derivatives of arbitrary order, in a general geometric setting. Our main motivation is the application to stability of non-linear geometric equations, primarily Ricci flow, which will be presented in a companion paper. The arguments in this paper use that many geometric Schrödinger operators can be written as the square of Dirac type operators. By a remarkable result of Wang, this is even true for the Lichnerowicz Laplacian, under the assumption of a parallel spinor. Our analysis is based on a novel combination of the Fredholm theory for Dirac type operators on ALE manifolds and recent advances in the study of the heat kernel on non-compact manifolds.

Near-infrared K-band Spectroscopic Investigation of Seyfert 2 Nuclei in the CfA and 12 Micron Samples

description: We present near-infrared K-band slit spectra of the nuclei of 25 Seyfert 2 galaxies in the CfA and 12 micron samples. The strength of the CO absorption features at 2.3-2.4 micron produced by stars is measured in terms of a spectroscopic CO index. A clear anti-correlation between the observed CO index and the nuclear K-L color is present, suggesting that a featureless hot dust continuum heated by an AGN contributes significantly to the observed K-band fluxes in the nuclei of Seyfert 2 galaxies. After correction for this AGN contribution, we estimate nuclear stellar K-band luminosities for all sources, and CO indices for sources with modestly large observed CO indices. The corrected CO indices for 10 (=40%) Seyfert 2 nuclei are found to be as high as those observed in star-forming or elliptical (=spheroidal) galaxies. We combine the K-band data with measurements of the L-band 3.3 micron polycyclic aromatic hydrocarbon (PAH) emission feature, another powerful indicator for star-formation, and find that the 3.3 micron PAH to K-band stellar luminosity ratios are substantially smaller than those of starburst galaxies. Our results suggest that the 3.3 micron PAH emission originates in the putative nuclear starbursts in the dusty tori surrounding the AGNs, because of its high surface brightness, whereas the K-band CO absorption features detected at the nuclei are dominated by old bulge (=spheroid) stars, and thus may not be a powerful indicator for the nuclear starbursts. We see no clear difference in the strength of the CO absorption and PAH emission features between the CfA and 12 micron Seyfert 2s.

Naming

Publisher: name: University of British Columbia

description: Naming is a narrative strategy that serves to explicate the conceptual model the strategy is drawn from. Through a close reading and examination of the narrative strategies in David Malouf's short stories "Jacko's Reach" and "Black soil Country" and his novel Remembering Babylon, and Jack Hodgins' short stories "Separating" and "Spit Delaney's Island" and his novel Innocent Cities, my thesis proposes that names are stories and naming is storytelling. This thesis offers a model of forward/lateral thinking as a structure that performs, self-consciously, the layering or embedding of stories within names. Further, this thesis also contains critical engagement with similar layerings in the work of Fred Wah, Anne Carson, Laurie Ricou, Thomas King, Don McKay, Denis Lee, and Tim Lilburn. Taken together, these diverse writers' thinking on naming and storytelling respond in my thesis to Ecocritical and Postcolonial theoretical modes of textual address and analysis.
An Efficient Block Circulant Preconditioner For Simulating Fracture Using Large Fuse Networks

description: {\it Critical slowing down} associated with the iterative solvers close to the critical point often hinders large-scale numerical simulation of fracture using discrete lattice networks. This paper presents a block circlant preconditioner for iterative solvers for the simulation of progressive fracture in disordered, quasi-brittle materials using large discrete lattice networks. The average computational cost of the present alorithm per iteration is $O(rs log s) + delops$, where the stiffness matrix ${\bf A}$ is partioned into $r$-by-$r$ blocks such that each block is an $s$-by-$s$ matrix, and $delops$ represents the operational count associated with solving a block-diagonal matrix with $r$-by-$r$ dense matrix blocks. This algorithm using the block circulant preconditioner is faster than the Fourier accelerated preconditioned conjugate gradient (PCG) algorithm, and alleviates the {\it critical slowing down} that is especially severe close to the critical point. Numerical results using random resistor networks substantiate the efficiency of the present algorithm.

description: The relationship between classical and quantum theory is central to the philosophy of physics, and any interpretation of quantum mechanics must clarify this relationship. Apart from gravity, quantum mechanics explains almost all known phenomena, from the structure of atoms, the laws of chemistry and condensed matter to the structure of the nucleus and the physics of elementary particles. It does all this with unprecedented precision.

description: The deterministic production of single-photons from two dimensional materials promises to usher in a new generation of photonic quantum devices. In this work, we outline criteria by which single-photon emission can be realised in two dimensional materials: spatial isolation, spectral filtering and low excitation of quantum emitters. We explore how these criteria can be fulfilled in atomically thin transition metal dichalcogenides, where excitonic physics dictates the observed photoemission. In particular, we model the effect of defects and localised strain, in accordance with the most common experimental realisations, on the photon statistics of emitted light. Moreover, we demonstrate that an optical cavity has a negative impact on the photon statistics, suppressing the single-photon character of the emission by diminishing the effect of spectral filtering on the emitted light. Our work provides a theoretical framework revealing criteria necessary to facilitate single-photon emission in two-dimensional materials and thus can guide future experimental studies in this field.

description: We study the problem of transmitting classical information using quantum Gaussian states on a family of phase-noise channels with a finite decoherence time, such that the phase-reference is lost after $m$ consecutive uses of the transmission line. This problem is relevant for long-distance communication in free space and optical fiber, where phase noise is typically considered as a limiting factor. The Holevo capacity of these channels is always attained with photon-number encodings, challenging with current technology. Hence for coherent-state encodings the optimal rate depends only on the total-energy distribution and we provide upper and lower bounds for all $m$, the latter attainable at low energies with on/off modulation and photodetection. We generalize this lower bound to squeezed-coherent encodings, exhibiting for the first time to our knowledge an unconditional advantage with respect to any coherent encoding for $m=1$ and a considerable advantage with respect to its direct coherent counterpart for $m>1$. This advantage is robust with respect to moderate attenuation, and persists in a regime where Fock encodings with up to two-photon states are also suboptimal. Finally, we show that the use of part of the energy to establish a reference frame is sub-optimal even at large energies. Our results represent a key departure from the case of phase-covariant Gaussian channels and constitute a proof-of-principle of the advantages of using non-classical, squeezed light in a motivated communication setting.

description: Mykotoxine [„Schimmelpilzgifte“] sind Stoffwechselprodukte bestimmter Pilze. Der Konsum Mykotoxin-belasteter Lebensmittel kann insbesondere für Risikogruppen unter den Verbrauchern ein Gesundheitsrisiko darstellen. Wichtige Mykotoxin-Bildner finden sich in der Pilzgattung Fusarium, als deren Leittoxin das Deoxynivalenol (DON) gilt. Besonders gravierend ist, dass sich das Vorkommen von Fusarium-Mykotoxinen allgemein sowie von DON speziell bisher nicht vollständig vermeiden lässt und – witterungsabhängig – insbesondere in sogenannten „Fusarium-Jahren“ ein nennenswerter Befall möglich ist. Hierdurch können bestimmte Verbrauchergruppen die unbedenkliche tolerierbare Tagesaufnahmerate erheblich überschreiten. Der erste Teil dieses Beitrags betrachtet den aktuellen Stand des Verbraucherschutzes vor DON. Dabei wird deutlich, dass eine Inkompatibilität zwischen den zulässigen Höchstgehalten und der gesundheitlich unbedenklichen Aufnahmerate besteht. Im zweiten Teil betrachten wir, wie man das aus dieser Inkompatibilität resultierende Gesundheitsrisiko verringern kann, wobei wir uns auf die Ergebnisse einer Expertenbefragung stützen.

description: We investigate a holographic relation between Einstein Gauss-Bonnet gravity in $n$ dimensions and its dual field theory in ($n-1$) dimensions. We briefly review the AdS/CFT correspondence for the entropy in the $n$-dimensional Einstein gravity and consider its extension to the case of the $n$-dimensional Einstein Gauss-Bonnet gravity. We show that there is a holographic relation between entropies of an Einstein Gauss-Bonnet black hole in the bulk and the corresponding radiation on the brane in the high temperature limit. In particular, we find that the Hubble entropy evaluated when the brane crosses the horizon also coincides with the black hole entropy in the high temperature limit.
