description: We present the numerical code TAURUS_vap that solves the variation after particle-number projection equations for symmetry-unrestricted real Bogoliubov quasiparticle states represented in a spherical harmonic oscillator basis. The model space considered is invariant under spatial and isospin rotations but no specific set of orbits is assumed such that the code can carry out both valence-space and no-core calculations. In addition, no number parity is assumed for the Bogoliubov quasiparticle states such that the code can be used to describe even-even, odd-even and odd-odd nuclei. The variational procedure can be performed under several simultaneous constraints on the expectation values of a variety of operators such as the multipole deformations, the pairing field or the components of the angular momentum. To demonstrate the potential and versatility of the code, we perform several example calculations using an empirical shell-model interaction as well as a chiral interaction. The ability to perform advanced variational Bogoliubov calculations offered by this code will, we hope, be beneficial to the shell model and ab initio communities.

description: Can a gravitational lens magnify gravity? Leading theories of gravity likely indicate "no", but the possibility might be testable by using our Sun as a gravitational lens and carefully aligning a satellite past the minimum transparent focal distance of about 25 AU. Here the magnitude of a maximal effect is estimated and found potentially observable.

A Robust Iterative Unfolding Method for Signal Processing
Creators: name: László, András
Publisher: name: arXiv
Year: 2006
Subjects: subject: Mathematical Physics (math-ph)
subject: FOS: Physical sciences

description: There is a well-known series expansion (Neumann series) in functional analysis for perturbative inversion of specific operators on Banach spaces. However, operators that appear in signal processing (e.g. folding and convolution of probability density functions), in general, do not satisfy the usual convergence condition of that series expansion. This article provides some theorems on the convergence criteria of a similar series expansion for this more general case, which is not covered yet by the literature. The main result is that a series expansion provides a robust unbiased unfolding and deconvolution method. For the case of the deconvolution, such a series expansion can always be applied, and the method always recovers the maximum possible information about the initial probability density function, thus the method is optimal in this sense. A very significant advantage of the presented method is that one does not have to introduce ad hoc frequency regulations etc., as in the case of usual naive deconvolution methods. For the case of general unfolding problems, we present a computer-testable sufficient condition for the convergence of the series expansion in question. Some test examples and physics applications are also given. The most important physics example shall be (which originally motivated our survey on this topic) the case of pi^0 --> gamma+gamma particle decay: we show that one can recover the initial pi^0 momentum density function form the measured single gamma momentum density function by our series expansion.

description: We study the response of a thermal state of an Ising chain to a nonlocal non-Hermitian perturbation, which coalesces the topological Kramer-like degeneracy in the ferromagnetic phase. The dynamic responses for initial thermal states in different quantum phases are distinct. The final state always approaches its half component with a fixed parity in the ferromagnetic phase but remains almost unchanged in the paramagnetic phase. This indicates that the phase diagram at zero temperature is completely preserved at finite temperatures. Numerical simulations for Loschmidt echoes demonstrate such dynamical behaviors in finite-size systems. In addition, it provides a clear manifestation of the bulk-boundary correspondence at nonzero temperatures. This work presents an alternative approach to understanding the quantum phase transitions of quantum spin systems at nonzero temperatures.

UN NUOVO DUVALIUS DEI MONTI MARTANI (UMBRIA) (Coleoptera, Carabidae)

Publisher: name: Fragmenta Entomologica
Year: 2006

description: Viene descritto Duvalius consortii n. sp. del Monte Martano in Umbria: anoftalmo, con habitus molto specializzato e quindi insolito per un endogeo. In base alla struttura dell’organo genitale maschile la nuova specie risulta non inquadrabile in nessuno dei gruppi di specie già noti (Magrini 1997, 1998). La forma dell’edeago, corto, tozzo e uncinato inferiormente all’apice è ben diversa da quella di tutti i Duvalius noti, mentre la lamella copulatrice si discosta nettamente da quella delle specie dell’Italia centro-meridionale, ricordando solo vagamente la forma di quella di alcuni gruppi alpini, come Duvalius boldorii Jeannel, 1926, ma riteniamo che si tratti sicuramente solo di una convergenza evolutiva. Per questo taxon viene pertanto considerata una nuova linea filetica nella quale istituiamo un “gruppo consortii”.

On the importance of the wind emission to the optical continuum of OB supergiants

description: Thermal wind emission in the form of free-free and free-bound emission is known to show up in the infrared and radio continuum of hot and massive stars. For OB supergiants with moderate mass loss rates and a wind velocity distribution with β= 0.8...1.0, no influence of the wind to the optical continuum, i.e. for λ< 1 micron, is expected. Investigations of stellar and wind parameters of OB supergiants over the last few years suggest, however, that for many objects βis much higher than 1.0, reaching values up to 3.5. We investigate the influence of the free-free and free-bound emission on the emerging radiation, especially at optical wavelengths, from OB supergiants having wind velocity distributions with β> 1. For the case of a spherically symmetric, isothermal wind in local thermodynamical equilibrium (LTE) we calculate the free-free and free-bound processes and the emerging wind and total continuum spectra. We localize the generation region of the optical wind continuum and especially focus on the influence of a β-type wind velocity distribution with β> 1 on the formation of the wind continuum at optical wavelengths. The optical wind continuum is found to be generated within about 2 R_* which is exactly the wind region where βstrongly influences the density distribution. We find that for β> 1, the continuum of a typical OB supergiant can indeed be contaminated with thermal wind emission, even at optical wavelengths. The strong increase in the optical wind emission is dominantly produced by free-bound processes.

description: The dynamical reaction of the particles accelerated at a shock front by the first order Fermi process can be determined within kinetic models that account for both the hydrodynamics of the shocked fluid and the transport of the accelerated particles. These models predict the appearance of multiple solutions, all physically allowed. We discuss here the role of injection in selecting the real solution, in the framework of a simple phenomenological recipe, which is a variation of what is sometimes referred to as thermal leakage. In this context we show that multiple solutions basically disappear and when they are present they are limited to rather peculiar values of the parameters. We also provide a quantitative calculation of the efficiency of particle acceleration at cosmic ray modified shocks and we identify the fraction of energy which is advected downstream and that of particles escaping the system from upstream infinity at the maximum momentum. The consequences of efficient particle acceleration for shock heating are also discussed.

Surviving within the perimeter : how palliative care patients make meaning of living while dying of terminal cancer
Creators: name: Bodell, Kathleen V.
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to discover how palliative cancer patients experience living while they are dying. A naturalistic approach, interpretive description, was used to identify and interpret themes. Data collection consisted of unstructured interviews with 6 patients with a prognosis of less than 6 months. Data was transcribed and analyzed systematically. Emerging findings were validated with participants and revealed 3 major themes: coping with a terminal illness, making sense of the situation, and surviving within the perimeter. Participants utilized a unique combination of coping styles and resources. Some reflected on the experience, while others ignored the psychological and spiritual aspects of the situation. All participants had a matter-of-fact acceptance that the situation could not be changed. They acknowledged their inevitable death but did not dwell on it. They maintained hope by being open to positive outcomes and using treatments that may make them feel better. Meaning related to doing what must be done in a bad situation while never letting go of the hope that the situation could improve. The participants focused mainly on staying alive (eating to maintain weight and gain strength) and accomplishing physical activities (by working around fatigue and other symptoms). Meaning was attached to physical accomplishments. Participants described themselves as surviving within a smaller perimeter of life.

description: Four different applications of spectral proper orthogonal decomposition (SPOD): low-rank reconstruction, denoising, frequency-time analysis, and prewhitening are demonstrated on large-eddy simulation data of a turbulent jet. SPOD-based low-rank reconstruction can be performed by direct inversion of a truncated SPOD. This spectral inversion problem, however, is ambiguous since SPOD relies on spectral estimation. We demonstrate SPOD-based flow field reconstruction using direct inversion of the SPOD algorithm (frequency-domain approach) and propose an alternative approach based on projection of the time series data onto the modes (time-domain approach). While the SPOD optimally represents the flow in a statistical sense, the time-domain approach seeks an optimal reconstruction of each instantaneous flow field. We further propose a SPOD-based denoising strategy that is based on hard-thresholding of the SPOD eigenvalues. The proposed strategy achieves significant noise reduction while facilitating drastic data compression. In contrast to standard methods of frequency-time analysis such as wavelet transform, a proposed SPOD-based approach yields a spectrogram that characterizes the temporal evolution of spatially coherent flow structures. In the frequency-domain, time-varying expansion coefficients can be obtained by basing the SPOD on a sliding window. This approach, however, is computationally intractable, and an alternative strategy based on convolution in the time-domain is presented. When applied to the turbulent jet data, SPOD-based frequency-time analysis reveals that the intermittent occurrence of large-scale coherent structures is directly associated with high-energy events. This work suggests that the time-domain approach is preferable for low-rank reconstruction of individual snapshots, and the frequency-domain approach for denoising and frequency-time analysis.

description: This paper develops a scattering theory to examine how point impurities affect transport through quantum wires. While some of our new results apply specifically to hard-walled wires, others--for example, an effective optical theorem for two-dimensional waveguides--are more general. We apply the method of images to the hard-walled guide, explicitly showing how scattering from an impurity affects the wire's conductance. We express the effective cross section of a confined scatterer entirely in terms of the empty waveguide's Green's function, suggesting a way in which to use semiclassical methods to understand transport properties of smooth wires. In addition to predicting some new phenomena, our approach provides a simple physical picture for previously observed effects such as conductance dips and confinement-induced resonances.

description: We have determined the ratios of total to selective extinction in the near-infrared bands (J, H, Ks) toward the Galactic center from the observations of the region |l| < 2.0deg and 0.5deg < |b| < 1.0deg with the IRSF telescope and the SIRIUS camera. Using the positions of red clump stars in color-magnitude diagrams as a tracer of the extinction and reddening, we determine the average of the ratios of total to selective extinction to be A(Ks)/E(H-Ks) = 1.44+-0.01, A(Ks)/E(J-Ks) = 0.494+-0.006, and A(H)/E(J-H) = 1.42+-0.02, which are significantly smaller than those obtained in previous studies. From these ratios, we estimate that A(J) : A(H) : A(Ks) = 1 : 0.573+-0.009 : 0.331+-0.004 and E(J-H)/E(H-Ks) = 1.72+-0.04, and we find that the power law A(lambda) \propto lambda^{-1.99+-0.02} is a good approximation over these wavelengths. Moreover, we find a small variation in A(Ks)/E(H-Ks) across our survey. This suggests that the infrared extinction law changes from one line of sight to another, and the so-called ``universality'' does not necessarily hold in the infrared wavelengths.

description: The merging cluster of galaxies A2255 is covered by the Sloan Digital Sky Survey (SDSS) survey. In this paper we perform a morphological classification on the basis of the SDSS imaging and spectral data, and investigate the morphological dependence of the star formation rates (SFRs) for these member galaxies. As we expect, a tight correlation between the normalized SFR by stellar mass (SFR/M$_*$) and the H$α$ equivalent width is found for the late-type galaxies in A2255. The correlation of SFR/M$_*$ with the continuum break strength at 4000 Åis also confirmed. The SFR/M$_*$ - M$_*$ correlation is found for both the early- and late-type galaxies, indicating that the star formation activity tends to be suppressed when the assembled stellar mass M$_*$) increases, and this correlation is tighter and steeper for the late-type cluster galaxies. Compared with the mass range of field spiral galaxies, only two massive late-type galaxies with M$_*>10^{11}$ M$_{\odot}$ are survived in A2255, suggesting that the gas disks of massive spiral galaxies could have been tidally stripped during cluster formation. Additionally, the SFR variation with the projected radial distance are found to be heavily dependent upon galaxy morphology: the early-type galaxies have a very weak inner decrease in SFR/M$_*$, while the inner late-type galaxies tend to have higher SFR/M$_*$ values than the outer late-types. This may suggest that the galaxy-scale turbulence stimulated by the merging of subclusters might have played different roles on early- and late-type galaxies, which leads to a suppression of the star formation activity for E/S0 galaxies and a SFR enhancement for spiral and irregular galaxies.

description: In this work, trions in two-dimensional (2D) space are studied by variational method with trial wavefunctions being constructed by linear combinations of 2D slater-type orbitals (STOs). Via this method, trion energy levels and wavefunctions can be calculated efficiently with fairly good accuracy. We first apply this method to study trion energy levels in a 2D hydrogen-like system with respect to a wide range of mass ratios and screening lengths. We find that the ground-state trion is bound for the whole parameter range, and an excited-state trion with antisymmetric permutation of electrons with finite angular momentum is bound for large electron-hole mass ratios or long screening lengths. The binding energies of ground-state trions calculated by the present method agree well with those calculated by more sophisticated but computationally-demanding methods. We then calculate trion states in various monolayer transition metal dichalcogenides (TMDCs) by using this method with the inclusion of electron-hole exchange (EHX) interaction. For TMDCs, we found that the effect of EHX can be significant in determining the trion binding energy and the possible existence of stable excited-state trions.

description: We describe a simple hybrid superconductor$|$ferromagnetic-insulator structure manifesting spin-resolved Andreev bound states in which dynamic magnetization is employed to probe spin related physics. We show that, at low bias and below $T_c$, the transfer of spin angular momentum pumped by an externally driven ferromagnetic insulator is greatly affected by the formation of spin-resolved Andreev bound states. Our results indicate that these bound states capture the essential physics of condensate-facilitated spin flow. For finite thicknesses of the superconducting layer, comparable to the coherence length, resonant Andreev bound states render highly transmitting subgap spin transport channels. We point out that the resonant enhancement of the subgap transport channels establishes a prototype Fabry-Pérot resonator for spin pumping.
Marketing the Mediterranean Diet: Some Comments on Issues and Opportunities

description: "The Mediterranean Diet" is a commonly used term in the U.S. denoting healthful eating and a healthy lifestyle. It appears to be inspired by the traditional diets of two Mediterranean countries based on post-World War II studies conducted in Naples, Italy and Crete. Popularization of the Mediterranean diet is associated with increased demand for red wine and olive oil in the United States. As noted in the American Heart Association (AHA) website, there is no one "Mediterranean" diet. The Mediterranean diet, as typically presented, appears to be inspired by traditional diets in Southern Italy, Greece, and Spain. The AHA outlines the common characteristics of the Mediterranean dietary pattern. At least two non-profit organizations promote their version of a Mediterranean diet pyramid, and hundreds of books present their version of the Mediterranean diet. There appears to be an outstanding opportunity for a well-funded and motivated organization to effectively market a Mediterranean diet plan, based on accepted marketing models. Research on market segments, product definition and product positioning will be required. Questions to be considered relate to the effectiveness of diet pyramids, diet benefits sought by various consumer segments, and the medical and health benefits of individual food products as documented by medical and nutrition research. Examples of the health and nutrition research and promotion programs for four California commodity groups provide information on an alternative approach to presenting information on diet and health.

description: We examine the recently proposed relations between black hole entropy and the topological string in the context of type II/heterotic string dual models. We consider the degeneracies of perturbative heterotic BPS states. In several examples with N=4 and N=2 supersymmetry, we show that the macroscopic degeneracy of small black holes agrees to all orders with the microscopic degeneracy, but misses non-perturbative corrections which are computable on the heterotic side. Using these examples we refine the previous proposals and comment on their domain of validity as well as on the relevance of helicity supertraces.

description: Single- and multi-layer complex networks have been proven as a powerful tool to study the dynamics within social, technological,or natural systems. An often observed common goal there is to optimize these systems for specific purposes by minimizing certain costs while maximizing a desired output. Acknowledging that especially real-world systems from the coupled socio-ecological realm are highly intertwined this work exemplifies that in such systems the optimization of a certain subsystem, e.g., to increase the resilience against external pressure in an ecological network, may unexpectedly diminish the stability of the whole coupled system. For this purpose we utilize an adaptation of a previously proposed conceptual bilayer network model composed of an ecological network of diffusively coupled resources co-evolving with a social network of interacting agents that harvest these resources and learn each other's strategies depending on individual success. We derive an optimal coupling strength that prevents a collapse in as many resources as possible if one assumes that the agents' strategies remain constant over time. However, we then show that if agents socially learn and adapt strategies according to their neighbors' success, this optimal coupling strength is revealed to be a critical parameter above which the probability for a global collapse in terms of irreversibly depleted resources is high -- an effect that we denote the tragedy of the optimizer. We thus find that measures which stabilize the dynamics within a certain part of a larger co-evolutionary system may unexpectedly cause the emergence of novel undesired globally stable states. Our results therefore underline the importance of holistic approaches for managing socio-ecological systems because stabilizing effects which focus on single subsystems may be counter-beneficial for the system as a whole.

Making happyland : the spectacularization and purification of downtown Vancouve
Creators: name: Todd, Kamala

description: Downtown Vancouver is becoming a spectacular place. Reflecting dominant trends found in many restructuring Canadian cities, its landscape has become increasingly aestheticized, privatized, consumption-based, and regulated. Since the late-1960s, boosters have worked to strengthen Vancouver's position in the international scene by staging it as a world class city, an inviting and exciting destination. To attract desired publics, downtown has been framed as the alluring gateway, the spectacular centre, the glittering jewel of Vancouver. Making this convivial centre—which I call Happyland—has involved remaking and reimaging downtown to 'upgrade' its perceived 'decay'. Like many North American central cities in the 1960s, with the advent of suburbanization and general economic decline, downtown Vancouver's role as the major shopping and entertainment centre of 'respectable' citizens seriously waned. New landscapes took shape as into the marginalizing spaces new publics made their places and inscribed their cultures. Parts of downtown became widely stigmatized as degraded and neglected, as taken over by 'undesirables'. Thus, making Happyland has largely been about 'civilizing' downtown—involving not only dramatic redevelopment, but also heavy marketing and increased policing. I read the remaking of downtown—Robson and Granville Streets in particular—by analyzing the changing landscape, local media, City decisions, place marketing, and the voices of various actors from multiple sources, including personal interviews. While the dominant narrative celebrates an urban renaissance, I argue that downtown is being purified, whereby a tightly scripted order is being fixed in which certain people, cultures, signs are 'out of place' and subjected to increasing levels of regulation. In particular, street youth have been identified as 'pests' who 'spoil' the desired clean, ordered, happy image. I see the demonization of street youth as reflecting wider relations of power. I argue that the narrative of Happyland, the dominant public culture being fixed downtown excludes other narratives, experiences, visions. Street youth narratives—from personal interviews and their own writings in a local 'zine—are testimony of this diversity. I argue that for this city and society to be truly inclusive and livable, as the rhetoric claims, such voices of citizens have to be given space and validity.

description: General equilibrium (GE) techniques have recently been used to simulate policy impacts for neighbouring or different rural areas, thus focussing on the important spatial aspect of such policies. A Social Accounting Matrix (SAM) represents production, households, government, etc. in matrix form, while computable GE models introduce greater behavioural flexibility at the cost of parameterisation. Several SAM and CGE models have recently been built for rural regions, while others have tried to represent rural-urban linkages. This paper presents two SAM applications, and one current CGE approach. The first SAM was developed for the analysis of the economic impact of Objective 1 policy on six remote rural areas, including two in Greece. Six specific regional SAMs were used to quantify the growth-generation effects of EU policies and scenarios on these local economies. The second effort used a hybrid three-area SAM for two different rural areas and an adjacent city in Crete to assess the diffusion patterns of economic impacts generated by three types of CAP measure in one of the rural areas. A CGE example, from the ongoing TERA project, seeks to model the determinants of economic agglomeration, and will attempt to cope with rural/urban distance and environmental externalities. Advantages of the SAM approach include its simplicity and availability of data and software. Disadvantages include significant data needs, linear behaviour, no real modelling of growth (development) or price changes, and the fact that some policies apply to many sectors in unknown way. The CGE approach may overcome some of these problems.

description: A focus of recent experimental and theoretical studies on heavy fermion systems close to antiferromagnetic (AFM) quantum critical points (QCP) is directed toward revealing the nature of the fixed point, i.e., whether it is an itinerant antiferromagnet [spin density wave (SDW)] type or a locally-critical fixed point. The relevance of the local QCP was proposed to explain the E/T-scaling with an anomalous exponent observed for the AFM QCP of CeCu_{5.9}Au_{0.1}. In this work, we have investigated an AFM QCP of another archetypal heavy fermion system Ce(Ru_{1-x}Rh_x)_2Si_2 with x = 0 and 0.03 (sim x_c) using single-crystalline neutron scattering. Accurate measurements of the dynamical susceptibility Im[chi(Q,E)] at the AFM wave vector Q = 0.35 c^* have shown that Im[chi(Q,E)] is well described by a Lorentzian and its energy width Gamma(Q), i.e., the inverse correlation time depends on temperature as Gamma(Q) = c_1 + c_2 T^{3/2 +- 0.1}, where c_1 and c_2 are x dependent constants, in low temperature ranges.This critical exponent 3/2 proves that the QCP is controlled by the SDW QCP in three space dimensions studied by the renormalization group and self-consistent renormalization theories.

description: The present paper investigates the free-riding problem in determining product quality within cooperatives in a vertically related market. Whereas the individual member has to bear all costs associated with higher quality, the benefits of delivering higher quality have to be shared among all members. On the basis of a Mixed-Oligopoly model, we show that the free-rider problem in the supply of high-quality products, although important for the members of the cooperative, may not be strong enough to ensure that firms will always supply higher quality than cooperatives. Whether the cooperative can overcome the free-riding problem and supply a final product of high quality is shown to depend on the consumer's valuation of quality, the costs of producing high quality, the way in which the quality of the final product is determined from the quality levels of the inputs delivered as well as on the number of members of the cooperative.

description: The Italian Industrial Districts (IDs) are now considered in the national and international literature as one of the main factors of the successful and rapid industrial development of Italy after the Second World War. In this paper we outline the general characteristics of the IDs approach and then the distinctive figures of the agrifood districts. A mosaic type of development characterised the geographical distribution of the different agrifood districts in the Italian experience. The different origins of agrifood districts often determines their production and structural characteristics of firms, with a relevant role of SMEs. In many cases, these districts originated from handcraft traditions and specific local demand. Their specialized production is often related to typical or high-quality products. The increasing demand for quality and typical food products might widen the possibility of developing local and regional food districts. In the second part of the paper, we have evaluated the economic performance and technical efficiency of a panel of firms in the meat sector which belong or not to the districts, for the period 1998-2002. Some very interesting results have been obtained from the economic and financial analysis on balance sheets of a large number of firms in the meat processing. The stochastic production frontier has been utilized to measure the 'district effect'. We have noticed that in the last years, the 'district effect' has been reducing according to the general difficulties of Italian industrial sector.

description: Since the rapid expansion of modern retailers in Turkish agro-food market, competent intermediary's forms are required to match up their exigent demand in fresh fruit and vegetables (thereafter FFV) procurement - namely, volume, regularity or quality- with a very fragmented national supply provided by small family farms. In this context, the aim of this paper is twofold: it first develops a unified theoretical framework that compares the costs incurred by producers when deciding to market their produce through a private agent or through a marketing cooperative. Drawing on marketing cooperatives theories and transaction cost arguments, we put forward that these systems do not prove the same ability to allow for quality upgrading, above all at the producer's level. Second, we analyze on this basis the recent evolution of the FFV sector in Turkey: the Turkish Wholesale Market Law enacted 1995 establishes commission producer's agents on FFV wholesale market halls who effectively collect an atomized supply and guarantee the access of small producers to large scale markets. Moreover, the simultaneous attempt to promote traditional cooperatives as alternative channels turns out to be less successful: small size, lack of funding and skill shortage hampered their development. However, public authorities recently promote the emergence of new types of marketing cooperatives whose initial endowment in capital and technical skills is high. The latter progressively turn to offensive strategies of quality upgrading and market access to new opportunities, whereby they have to set screening rules marginalizing small and vulnerable producers in order to achieve this goal. In our view, this evolution in the governmental intervention illustrates a determinant trade-off faced by the public authorities: namely, the choice between assuring the inclusion of the major part of producers in the market and boosting productivity and quality upgrading at the production level for more demanding markets.
