description: Nachhaltigkeit wird häufig als wirkungslose Leerformel kritisiert. Der Artikel unterstreicht demgegenüber die normativen und funktionalen Qualitäten semantischer Leere. Im Rückgriff auch Laclaus Theorie des leeren Signifikanten und Luhmanns systemtheoretische Wissenssoziologie wird dargelegt, dass eine inhaltliche Abstraktheit von Nachhaltigkeitskonzepten sowohl Bedingung als auch Folge einer erfolgreichen Implementation in moderne, demokratisch verfasste Gesellschaften darstellt. Als Leerformel manifestiert Nachhaltigkeit demokratische Werte und die Konstitution einer funktional ausdifferenzierten Systemstruktur. Diese Thesen werden abschließend für eine Nachhaltigkeitskritik ausgewertet, die sich ihrer gesellschaftlichen Bedingungen bewusst ist. 

Sustainability is often criticized as an ineffective empty formula. The article highlights the normative and functional qualities of semantic emptiness. In recourse to Laclau‘s theory of empty signifiers and Luhmann‘s system-theoretical sociology of knowledge, it is made explicit that the abstractness of sustainability concepts is both a condition and a consequence of successful implementation into modern, democratic societies. As an empty formula, sustainability thus manifests democratic values and the constitution of a functionally differentiated system structure. These theses are finally evaluated for a sustainability critique that is aware of its social conditions.

description: EM Cygni is a Z Cam-subtype eclipsing dwarf nova. Its orbital period variations were reported in the past but the results were in conflict to each other while other studies allowed the possibility of no period variation. In this study we report accurate new times of minima of this eclipsing binary and update its O-C diagram. We also estimate the mass transfer rate in EM Cygni system and conclude that the mass transfer is far from the critical value. The mass transfer rate determined from the eclipse timings is in agreement with the spectroscopically determined value.

description: Perfect magnetic conductor (PMC) boundary conditions are dual to the more familiar perfect electric conductor (PEC) conditions and can be viewed as the electromagnetic analog of the boundary conditions in the bag model for hadrons in QCD. Recent advances and requirements in communication technologies have attracted great interest in PMC's and Casimir experiments involving structures that approximate PMC's may be carried out in the not too distant future. In this paper, we make a study of the zero-temperature PMC Casimir piston in $d+1$ dimensions. The PMC Casimir energy is explicitly evaluated by summing over $p+1$-dimensional Dirichlet energies where p ranges from 2 to $d$ inclusively. We derive two exact $d$-dimensional expressions for the Casimir force on the piston and find that the force is negative (attractive) in all dimensions. Both expressions are applied to the case of 2+1 and 3+1 dimensions. A spin-off from our work is a contribution to the PEC literature: we obtain a useful alternative expression for the PEC Casimir piston in 3+1 dimensions and also evaluate the Casimir force per unit area on an infinite strip, a geometry of experimental interest.

Leydigiopsis pulchra

description: 33. Leydigiopsis pulchra Van Damme et Sinev, 2013
Localities and specimens found: 50 – 4♀, 1♀ em, 2j; 51 – 4♀.
Distribution and ecology. This is a relatively rare species recently described from Thailand (Van Damme & Sinev 2013). It is also known in India, Cambodia, Laos, Myanmar and Vietnam, where it was listed in some sources as Leydigiopsis sp. or L. curvirostris Sars, 1901 before being described (Sanoamuang 1998; Sharma & Sharma 2007, 2012, 2017; Maiphae et al. 2008; Tanaka & Ohtaka 2010; Kotov et al. 2013b; Sinev & Korovchinsky 2013; Van Damme & Sinev 2013; Sinev 2016).
Representatives of the genus Leydigiopsis are considered to be true benthic cladocerans (Kotov 2006). The lifestyle and ecology of L. pulchra are still poorly understood. The species was recorded in eutrophic habitats rich in living and dead organic matter: swamps, forest ponds and small lakes (Sanoamuang 1998; Sinev & Korovchinsky 2013; Van Damme & Sinev 2013; Sinev 2016). We found it only in the samples from the root system of floating macrophytes (see Appendix 1).
Remarks. Van Damme & Sinev (2013) pointed out a possible hidden speciation within Asian populations of L. pulchra, which is reflected in the differences the authors found between individuals from Thailand and Vietnam.

description: I. Perianthomega clade
TAXONOMIC INFORMATION. — This clade contains a single genus, Perianthomega, with four phloem arcs in transversal section (Fig. 3D). The genus was placed previously in Tecomeae s.l. (Gentry 1992; Fischer et al. 2004; Table 1), but subsequently transferred into Bignonieae (Lohmann & Taylor 2014).
TOTAL NUMBER OF SPECIES IN THIS CLADE. — One species (Lohmann & Taylor 2014).
STUDIED SPECIES. — One species, Perianthomega vellozoi Bureau.
Regular phloem
Thin to thick fiber bands (Fig. 7A), without assemblages.
Variant phloem
General configuration. Non-fibrous, stratified, with approximately 12-18 rows of sieve tubes and phloem parenchyma cells between fiber bands (Fig. 7B). A tendency to a storied structure is evident in the cambial zone (Fig. 7D) and secondary xylem, less so in the secondary phloem (Fig. 7E).
Sieve tube elements. As seen in transverse section, each sieve element is associated with one companion cell (Fig. 7C), sometimes two, one at each opposite corner of the sieve element. Sieve tubes are solitary or radial and composed of 2-3 cells (Fig. 7B, C). As seen in longitudinal section, the sieve elements are short (<500 µm) (Fig. 7E) and their end walls are transverse to slightly inclined (Fig. 7D, E), bearing simple sieve plates (Fig. 7E).
Axial parenchyma. The phloem parenchyma forms a matrix where sieve elements and fiber bands are embedded (Fig. 7B, C). Long radial rows of phloem parenchyma, sometimes with more than 10 cells, are present. Furthermore, a crystalliferous parenchyma is found surrounding the fiber bands (Fig. 7C).
Fibers. The fiber bands are composed of 4-6 rows of cells (Fig. 7B).
Rays. Limiting rays are not present in Perianthomega. The rays are non-lignified, not even when crossing the fiber bands (Fig. 7B).
Crystals. Acicular crystals are present and more abundant in the crystalliferous parenchyma, although also found in all other cells of the phloem and ray parenchyma (Fig. 7C).
Periderm
Only one periderm is formed (Fig. 7F). The phellem is composed of evenly thin-walled cells. The phelloderm is thin, with less than three layers of cells (Fig. 7F).

description: We report the results of inelastic neutron scattering experiments on NpCoGa$_{5}$, an isostructural analogue of the PuCoGa$_{5}$ superconductor. Two energy scales characterize the magnetic response in the antiferromagnetic phase. One is related to a non-dispersive excitation between two crystal field levels. The other at lower energies corresponds to dispersive fluctuations emanating from the magnetic zone center. The fluctuations persist in the paramagnetic phase also, although weaker in intensity. This supports the possibility that magnetic fluctuations are present in PuCoGa$_{5}$, where unconventional d-wave superconductivity is achieved in the absence of magnetic order.

Regular phloem
Thick fiber bands (Fig. 8B), assemblages present (Fig. 8C).
Variant phloem
General configuration. Fibrous phloem (Fig. 8A, D), with some non-fibrous, parenchyma bands in alternation (Fig. 8A, D). Axial elements with either a tangential (Fig. 8A) or a radial arrangement (Fig. 8D).
Sieve tube elements. As seen in transverse section, each sieve element is associated with 1-3 companion cells (Fig. 8E), lying on the same corner of the sieve tube (Fig. 8E). The sieve elements are generally arranged in multiples of 2-3 in a radial or tangential disposition, sometimes in clusters (Fig. 8E). Sieve tubes of narrower radial diameter can be found associated with a parenchyma band (Fig. 8D). Such sieve tubes are found in radial multiples of 2-4 cells. As seen in longitudinal section, the sieve elements are thinner than 1 mm, with end walls inclined, bearing sieve plates with 6-10 sieve areas (Fig. 8F). Ray sieve-tube elements are common (Fig. 8F).
Axial parenchyma. The phloem parenchyma is sieve-tube-centric incomplete (Fig. 8D, E), not surrounding the entire sieve tube or sieve tube group, and commonly lignified (Fig. 8E). A parenchyma band of 3-4 rows of cells is present (Fig. 8A, D) associated with narrower sieve elements. In addition, radial rows of axial parenchyma cells are present in some places, sometimes entirely lignified
Fibers. Fibers form a matrix where all other cells can be found (Fig. 8A, D, E).
Rays. The limiting rays are lignified to both xylem and phloem sides, with a radial row of non-lignified cells between them (Fig. 8A). The wedge rays have randomly alternating portions that can be lignified or non-lignified (Fig. 8D, E).
Crystals. Acicular crystals are present in most of the phloem and ray parenchyma cells.
Periderm
Only one periderm is present. The phellem is stratified, composed of thin and thick-walled cells disposed in alternation. The phelloderm is thick, with more than three layers of cells, non-stratified (Table 2).

Funnel wall jets and the nature of the soft X-ray excess

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)

description: The smooth soft X-ray excess seen in many type-1 AGN can be well described by models of absorption in partially ionized material with a large velocity dispersion, often physically interpreted as a radiatively driven accretion disk wind. However, the state-of-the-art XSCORT code, which calculates the photoionized radiative transfer through a differentially outflowing absorber, shows that terminal velocities of order ~0.9c are required in order to reproduce the soft X-ray excess. Such a high outflow velocity rules out UV-line driving, continuum radiation driving, and thermal driving as mechanisms for producing the wind. Entrainment of material by the magnetically driven jet is the only plausible origin of such a high velocity flow, but numerical simulations of jets and associated outflows do not currently show sufficient material at high enough velocities to reproduce the soft X-ray excess. If the soft excess is produced by absorption then it seems more likely that the material is clumpy and/or only partially covers the source rather than forming a continuous outflow.

Ferredoxin T cell idiotype : linkage to immunoglobulin heavy chain alleles or the major histocompatibility complex
Creators: name: Singhai, Rakesh
Publisher: name: University of British Columbia
Year: 2010

description: An anti-idiotypic antiserum was raised in rabbits to a monoclonal antibody with specificity for one of the two antigenic determinants on the ferredoxin (Fd) molecule. The monoclonal antibody (Fd-B2) was derived from fusion of spleen cells from Fd-immune B10.BR (H-2[sup k], Igh[sup b]). Examination of an extensive number of samples of Fd-immune serum from B10.BR and other mouse strains established that the Fd-B2 idiotype is essentially never present in such sera in detectable concentrations (> 30 ng/ml). Administration of the anti-idiotypic antibody (anti-Fd-B2) i.v. to B10.BR mice, or treatment of B10.BR T-cell enriched populations with anti-Fd-B2 + complement prior to adoptive transfer to irradiated BI10.BR recipients followed by challenge with Fd resulted in a significant increase in the production of anti-Fd antibodies. This effect was specific and was not accompanied by a change in expression of the Fd-B2 idiotype in the antibody produced. Similarly, injection of 10 μg of Fd-B2 into B10.BR mice resulted in an enhanced anti-Fd response. When similar experiments were carried out using B10.D2 mice (H-2[sup k], Igh[sup b]), which are genetic non-responders to Fd, it was observed that treatment with anti-Fd-B2 followed by challenge with Fd resulted in production in treated animals of significant levels of antibody to Fd. Again, the antisera thus produced did not contain detectable levels of the Fd-B2 idiotype. Further experiments using high responder (H-2[sup k]) mice with Igh allotypes differing from the BIO strains (C57/BR, Igh[sup a], and RF/J, Igh[sup c]), showed that treatment of these animals with anti-Fd-B2 also resulted in a highly significant enhancement of the anti-Fd response. The implications of these findings are discussed.

STUDIED SPECIES. — One species, Manaosella cordifolia (DC.) A.H. Gentry.
Regular phloem
Thin to thick fiber bands, fibers tangentially elongated in some portions, assemblages absent.
Variant phloem
General configuration. Non-fibrous (Fig. 10A), with approximately 14-16 rows of sieve tubes and phloem parenchyma cells between fiber bands. The axial elements present a diffuse arrangement, sometimes with a radial tendency (Fig. 10 A-C).
Sieve-tube elements. As seen in transverse section, each sieve element is associated with one companion cell (Fig. 10C). Sieve tubes of two distinct diameters occur adjacent to one another and are predominantly solitary (Fig. 10B, C), occasionally radially disposed and arranged in multiples of 2-3. As seen in longitudinal section, the sieve elements are thinner than 1 mm and their end walls are inclined, bearing sieve plates with 7-15 sieve areas.
Axial parenchyma. The phloem parenchyma forms a matrix in which sieve elements and fiber bands are embedded (Fig. 10 AC). Sometimes radial rows of phloem parenchyma can be also detected between or next to sieve elements (Fig. 10B, C).
Fibers. The fiber bands in Manaosella bear cells that are conspicuously radially elongated (Fig. 10B), a feature not found in any other Bignonieae genus. The fiber bands are composed of 2-3 rows of cells, with the cells located in the center or upper portions of the band radially elongated.
Rays. The limiting rays are lignified only to the xylem face (Fig. 10A, B). The wedge rays are non-lignified, except when crossing the fiber bands (Fig. 10B, C).
Crystals. Acicular crystals are very abundant and are found in most cells of the phloem and ray parenchyma (Fig. 10C).
Periderm
A single periderm formed. The phellem is stratified, composed of thin and thick-walled cells in alternation. The phelloderm is thin, with less than three layers of cells, non-stratified (Table 2). Lenticels non-stratified, unlignified.

description: We present azimuthal anisotropy measurements in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 62.4 and 200 GeV. Comparison between reaction plane and cumulant $v_2$ measurements in Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV show that non-flow contributions, originating mainly from jets, influence the extracted $v_2$ for $p_T$ $\gtrsim$ 3.5 GeV/c. Number of constituent quark (NCQ) scaling of $v_2$, when studied as a function of transverse kinetic energy $KE_T$, is seen to hold for Au+Au collisions at $\sqrt{s_{NN}}$ = 62.4 and 200 GeV and for Cu+Cu collisions at $\sqrt{s_{NN}}$ = 200 GeV for $KE_{T}$ $\lesssim$ 1 GeV/c. Differential hexadecupole flow $v_4$ seems to exhibit scaling with integral $v_2$ for centrality $\le$ 40% as has been observed for differential $v_2$.

description: The apparent spectral evolution observed in the steep decay phase of many GRB early afterglows raises a great concern of the high-latitude "curvature effect" interpretation of this phase. However, previous curvature effect models only invoked a simple power law spectrum upon the cessation of the prompt internal emission. We investigate a model that invokes the "curvature effect" of a more general non-power-law spectrum and test this model with the Swift/XRT data of some GRBs. We show that one can reproduce both the observed lightcurve and the apparent spectral evolution of several GRBs using a model invoking a power-law spectrum with an exponential cut off. GRB 050814 is presented as an example.

description: We analyse the statistical pattern of seismicity before a 1-2 103 m3 chalk cliff collapse on the Normandie ocean shore, Western France. We show that a power law acceleration of seismicity rate and energy in both 40 Hz-1.5 kHz and 2 Hz-10kHz frequency range, is defined on 3 order of magnitude, within 2 hours from the collapse time. Simultaneously, the average size of the seismic events increases toward the time to failure. These in-situ results are derived from the only station located within one rupture length distance from the rock fall rupture plane. They mimic the "critical point" like behavior recovered from physical and numerical experiments before brittle failures and tertiary creep failures. Our analysis of this first seismic monitoring data of a cliff collapse suggests that the thermodynamic phase transition models for failure may apply for cliff collapse.

description: Well-determined physical parameters of 130 W UMa systems have been collected from the literature. Based on these data, the evolutionary status and dynamical evolution of W UMa systems are investigated. It is found that there is no evolutionary difference between W- and A-type systems in $M-J$ diagram which is consistent with the results derived from the analysis of observed spectral type, $M-R$ and $M-L$ diagrams of W UMa systems. $M-R$ and $M-L$ diagrams of W- and A-type systems indicate that a large amount of energy should be transferred from the more massive to the less massive component so that they are not in thermal equilibrium and undergo thermal relaxation oscillation (TRO). Meanwhile, the distribution of angular momentum, together with the distribution of mass ratio, suggests that the mass ratio of the observed W UMa systems is decreased with the decrease of their total mass. This could be the result of the dynamical evolution of W UMa systems which suffer angular momentum loss (AML) and mass loss due to magnetic stellar wind (MSW). Consequently, the tidal instability forces these systems towards the lower q values and finally to fast rotating single stars.

description: We present a study of pixel Colour Magnitude Diagrams (pCMDs) for a sample of 69 nearby galaxies chosen to span a wide range of Hubble types. Our goal is to determine how useful a pixel approach is for studying galaxies according to their stellar light distributions and content. The galaxy images were analysed on a pixel-by-pixel basis to reveal the structure of the individual pCMDs. We find that the average surface brightness (or projected mass density) in each pixel varies according to galaxy type. Early-type galaxies exihibit a clear ``prime sequence'' and some pCMDs of face-on spirals reveal ``inverse-L'' structures. We find that the colour dispersion at a given magnitude is found to be approximately constant in early-type galaxies but this quantity varies in the mid and late-types. We investigate individual galaxies and find that the pCMDs can be used to pick out morphological features. We discuss the discovery of ``Red Hooks'' in the pCMDs of six early-type galaxies and two spirals and postulate their origins. We develop quantitative methods to characterise the pCMDs, including measures of the blue-to-red light ratio and colour distributions of each galaxy and we organise these by morphological type. We compare the colours of the pixels in each galaxy with the stellar population models of Bruzual & Charlot (2003) to calculate star formation histories for each galaxy type and compare these to the stellar mass within each pixel. Maps of pixel stellar mass and mass-to-light ratio are compared to galaxy images. We apply the pCMD technique to three galaxies in the Hubble Ultra Deep Field to test the usefulness of the analysis at high redshift. We propose that these results can be used as part of a new system of automated classification of galaxies that can be applied at high redshift.

description: VII. Lundia clade
TAXONOMIC INFORMATION. — This clade contains a single genus, Lundia, with multiple of four phloem wedges in transversal section.
TOTAL NUMBER OF SPECIES IN THIS CLADE. — 13 species (Lohmann & Taylor 2014; Kaehler & Lohmann 2021a).
STUDIED SPECIES. — Five species, Lundia longa (Vahl) DC., L. damazioi C.DC., L. densiflora DC., L. virginalis DC., and L. nitidula DC.
Regular phloem
Thin fiber bands (Fig. 10H) and assemblages present.
Variant phloem
General configuration. Fibrous (Fig. 10G, I), with axial elements in a tangential to diagonal arrangement (Fig. 10G, I).
Sieve-tube elements. As seen in transverse section, each sieve element is associated with one companion cell, rarely two (Fig. 10I). The sieve elements may be solitary to multiples of 2-3 (Fig. 10I). Narrower sieve elements with just one companion cell may be found in a parenchyma band present in all species studied. As seen in longitudinal section, the sieve elements are long (over 1 mm) and their end walls are inclined, bearing sieve plates with 12-15 sieve areas.
Axial parenchyma. The phloem parenchyma is sieve-tube-centric to sieve-tube-centric incomplete, therefore surrounding or partially surrounding the groups of sieve elements (Fig. 10I). Furthermore, a parenchyma band composed of 2-3 cells of phloem parenchyma is associated with sieve elements of narrower diameter. The phloem parenchyma tends to form radial rows of 4-6 cells in some places.
Fibers. Fibers form the background tissue where all other cells are embedded (Fig. 10G, I).
Rays. The limiting rays are only lignified to the xylem face (10G). The wedge rays have randomly alternating portions lignified and non-lignified.
Crystals. Acicular crystals are present in the phloem and ray parenchyma across the entire phloem wedge (absent in Lundia longa).
Periderm
A single periderm formed. The phellem is non-stratified, composed of evenly thin-walled cells in Lundia corymbifera and L. virginalis. The phellem is stratified in Lundia longa, with alternating thin and thick-walled cells.The phelloderm is thick, with over three layers of cells, non-stratified (Table 2). The lenticels are non-stratified, with unlignified filling tissue (Table 2).

description: The goal of this work is to put constraints on the strength and structure of the magnetic field in the cluster of galaxies A2382. We investigate the relationship between magnetic field and Faraday rotation effects in the cluster, using numerical simulations as a reference for the observed polarization properties. For this purpose we present Very Large Array observations at 20 cm and 6 cm of two polarized radio sources embedded in A2382, and we obtained detailed rotation measure images for both of them. We simulated random three-dimensional magnetic field models with different power spectra and thus produced synthetic rotation measure images. By comparing our simulations with the observed polarization properties of the radio sources, we can determine the strength and the power spectrum of intra-cluster magnetic field fluctuations that best reproduce the observations. The data are consistent with a power law magnetic field power spectrum with the Kolmogorov index $n=11/3$, while the outer scale of the magnetic field fluctuations is of the order of 35 kpc. The average magnetic field strength at the cluster center is about 3 $μ$G and decreases in the external region as the square root of the electron gas density. The average magnetic field strength in the central 1 Mpc$^{3}$ is about 1 $μ$G.

description: Scanning transmission electron microscopy (STEM) is now the primary tool for exploring functional materials on the atomic level. Often, features of interest are highly localized in specific regions in the material, such as ferroelectric domain walls, extended defects, or second phase inclusions. Selecting regions to image for structural and chemical discovery via atomically resolved imaging has traditionally proceeded via human operators making semi-informed judgements on sampling locations and parameters. Recent efforts at automation for structural and physical discovery have pointed towards the use of "active learning" methods that utilize Bayesian optimization with surrogate models to quickly find relevant regions of interest. Yet despite the potential importance of this direction, there is a general lack of certainty in selecting relevant control algorithms and how to balance a priori knowledge of the material system with knowledge derived during experimentation. Here we address this gap by developing the automated experiment workflows with several combinations to both illustrate the effects of these choices and demonstrate the tradeoffs associated with each in terms of accuracy, robustness, and susceptibility to hyperparameters for structural discovery. We discuss possible methods to build descriptors using the raw image data and deep learning based semantic segmentation, as well as the implementation of variational autoencoder based representation. Furthermore, each workflow is applied to a range of feature sizes including NiO pillars within a La:SrMnO$_3$ matrix, ferroelectric domains in BiFeO$_3$, and topological defects in graphene. The code developed in this manuscript are open sourced and will be released at github.com/creangnc/AE_Workflows.

description: Theoretical study indicates that a contact binary system would merge into a rapidly rotating single star due to tidal instability when the spin angular momentum of the system is more than a third of its orbital angular momentum. Assuming that W UMa contact binary systems rigorously comply with the Roche geometry and the dynamical stability limit is at a contact degree of about 70%, we obtain that W UMa systems might suffer Darwin's instability when their mass ratios are in a region of about 0.076--0.078 and merge into the fast-rotating stars. This suggests that the W UMa systems with mass ratio $q\leq0.076$ can not be observed. Meanwhile, we find that the observed W UMa systems with a mass ratio of about 0.077, corresponding to a contact degree of about 86% would suffer tidal instability and merge into the single fast-rotating stars. This suggests that the dynamical stability limit for the observed W UMa systems is higher than the theoretical value, implying that the observed systems have probably suffered the loss of angular momentum due to gravitational wave radiation (GR) or magnetic stellar wind (MSW).

A hedonic cost function approach to agricultural land prices
Creators: name: Quan, Daniel Wah Choo
Publisher: name: University of British Columbia
Year: 2010

description: Since Sherwin Rosen's paper on implicit markets and hedonic functions, there has been an increase in the application of hedonics theory. These applications have almost exclusively dealt with consumer choice and the implicit consumer demand for attributes. The methodology usually entails the two stage procedure of initially obtaining implicit prices from the hedonics function and then using these prices as dependent variables in a system of bid functions. In this thesis, a system of bid functions for land attributes is derived from a Generalized Leotief cost function of the British Columbia dairy industry. These bid functions were estimated with land characteristics data from records of dairy land transactions. The proposed paper provides several interesting extensions to the present applied work in this area. The application of duality results in the specification and derivation of bid functions provide an important improvement in existing methodology since economic structure can be improsed and consistency of derivation can be obtained. Also, despite its popularity in consumption analysis, the application of hedonic theory in production and the derived demand for inputs have not been addressed. Two main results are discussed in the thesis. The first concerns identification of cost function parameters (and therefore the dual production technology) through the system of bid functions in the absence of input quantity data. The second result is that in the context of land attribute choices in agricultural production, the question of endogenous and exogenous implicit prices are important concerns as some implicit attribute prices are determined by non-production related factors. It is shown that linear homogeneity of attributes in the hedonic function is a necessary condition for exogenous implicit prices.

description: We determine the effects of quantum fluctuations about the T=0 mean field solution of the BCS-BEC crossover in a dilute Fermi gas using the functional integral method. These fluctuations are described in terms of the zero point motion of collective modes and the virtual scattering of gapped quasiparticles. We calculate their effects on various measurable properties, including chemical potential, ground state energy, the gap, the speed of sound and the Landau critical velocity. At unitarity, we find excellent agreement with quantum Monte Carlo and experimental results. In the BCS limit, we show analytically that we obtain Fermi liquid interaction corrections to thermodynamics including the Hartree shift. In the BEC limit, we show that the theory leads to an approximate description of the reduction of the scattering length for bosonic molecules and also obtain quantum depletion of the Lee-Yang form. At the end of the paper, we describe a method to include feedback of quantum fluctuations into the gap equation, and discuss the problems of self-consistent calculations in satisfying Goldstone's theorem and obtaining ultraviolet finite results at unitarity.

Colossal electroresistance effect around room temperature in LuFe2O4

description: A colossal electroresistance effect is observed around room temperature in a transition metal oxide LuFe2O4. The measurements of resistance under various applied voltages as well as the highly nonlinear current-voltage characteristics reveal that a small electric field is able to drive the material from the insulating state to a metallic state. The threshold field at which the insulating-metallic transition occurs, decreases exponentially with increasing temperature. We interpret this transition as a consequence of the breakdown of the charge-ordered state triggered by applied electric field, which is supported by the dramatic dielectric response in a small electric field. This colossal electroresistance effect as well as the high dielectric tunability around room temperature in low applied fields makes LuFe2O4 a very promising material for many applications.

Density dependent catchability coefficient in the Georgia Strait salmon sport fishery
Creators: name: Shardlow, Thomas Frost
Publisher: name: University of British Columbia
Year: 2010

description: This investigation examined the relationship between the catch per unit of effort (c/f) of salmon anglers and salmon abundance. The relationship was determined by using simultaneous estimates of both c/f and salmon abundance (n). Salmon in their natural marine environment were observed as they approached fishing gear. The components of catch, such as the number of fish approaching, attacking and biting the lure per unit of fished effort were video recorded. Salmon abundance was estimated simultaneously with catch and effort through the use of a chart recording echo sounder. The results showed that catch per unit of effort (c/f) was not linearly related to abundance (n) as in the simple expression: c/f = qn; where 'q', the catchability coefficient, is a constant proportion of the abundance caught by a nominal unit of fishing effort. In this study q was found not to be constant but to increase with abundance. This result contrasts with previous empirical studies of catchability in which estimates of q declined with fish abundance. However, because only historical catch records had been used to estimate catchability, few of the relevant details of the interaction between the fishing gear and fish were available. In the present study, video recordings of fish encounters with fishing gear suggest that feeding facilitation between salmon may be the mechanism underlying increcised catchability with abundance.
Demonstrating the negligible contribution of optical ACS/HST galaxies to source-subtracted cosmic infrared background fluctuations in deep IRAC/Spitzer images

description: We study the possible contribution of optical galaxies detected with the {\it Hubble} ACS instrument to the near-IR cosmic infrared (CIB) fluctuations in deep {\it Spitzer} images. The {\it Spitzer} data used in this analysis are obtained in the course of the GOODS project from which we select four independent $10^\prime\times10^\prime$ regions observed at both 3.6 and 4.5 \um. ACS source catalogs for all of these areas are used to construct maps containing only their emissions in the ACS $B, V, i, z$-bands. We find that deep Spitzer data exhibit CIB fluctuations remaining after removal of foreground galaxies of a very different clustering pattern at both 3.6 and 4.5 \um than the ACS galaxies could contribute. We also find that there are very good correlations between the ACS galaxies and the {\it removed} galaxies in the Spitzer maps, but practically no correlations remain with the residual Spitzer maps used to identify the CIB fluctuations. These contributions become negligible on larger scales used to probe the CIB fluctuations arising from clustering. This means that the ACS galaxies cannot contribute to the large-scale CIB fluctuations found in the residual Spitzer data. The absence of their contributions also means that the CIB fluctuations arise at $z\gsim 7.5$ as the Lyman break of their sources must be redshifted past the longest ACS band, or the fluctuations have to originate in the more local but extremely low luminosity galaxies.

description: The term preface in generally used in relation to a turn, i.e., a turn preface. Turn prefaces refer to elements that occur in turn-initial position (or in turn beginning, see Kim & Kuroshima 2013; see also Heritage & Sorjonen 2018). A turn-preface is thus a turn-initial element (such as a particle) – these terms are used interchangeably (e.g. Heritage & Sorjonen 2018: 8 talk about both "turn-initial well" and "well-prefaces").
