description: Development of broadband thermal sensors for the detection of, among others, radiation, single nanoparticles, or single molecules is of great interest. In recent years, photothermal spectroscopy based on the shift of the resonance frequency of stressed nanomechanical resonators has been successfully demonstrated. Here, we show the application of soft-clamped phononic crystal membranes made of silicon nitride as thermal sensors. It is experimentally demonstrated how a quasi-bandgap remains even at very low tensile stress, in agreement with finite element method simulations. An increase of the relative responsivity of the fundamental defect mode is found when compared to that of uniform square membranes of equal size, with enhancement factors as large as an order of magnitude. We then show phononic crystals engineered inside nanomechanical trampolines, which results in additional reduction of the tensile stress and increased thermal isolation, resulting in further enhancement of the responsivity. Finally, defect mode and bandgap tuning is shown by laser heating of the defect to the point where the fundamental defect mode completely leaves the bandgap.

description: Despite many successful applications, Cartesian Genetic Programming (CGP) suffers from limited scalability, especially when used for evolutionary circuit design. Considering the multiplier design problem, for example, the 5x5-bit multiplier represents the most complex circuit evolved from a randomly generated initial population. The efficiency of CGP highly depends on the performance of the point mutation operator, however, this operator is purely stochastic. This contrasts with the recent developments in Genetic Programming (GP), where advanced informed approaches such as semantic-aware operators are incorporated to improve the search space exploration capability of GP. In this paper, we propose a semantically-oriented mutation operator (SOMO) suitable for the evolutionary design of combinational circuits. SOMO uses semantics to determine the best value for each mutated gene. Compared to the common CGP and its variants as well as the recent versions of Semantic GP, the proposed method converges on common Boolean benchmarks substantially faster while keeping the phenotype size relatively small. The successfully evolved instances presented in this paper include 10-bit parity, 10+10-bit adder and 5x5-bit multiplier. The most complex circuits were evolved in less than one hour with a single-thread implementation running on a common CPU.

description: O presente trabalho analisa as políticas públicas de segurança alimentar como instrumentos de desenvolvimento nos espaços locais e regionais voltados ao objetivo de elevar as condições de renda e de emprego na agricultura familiar. Mostra que mecanismos institucionais desenvolvidos a partir de políticas públicas participativas podem promover o desenvolvimento rural local e regional com possibilidades de inclusão social. Tal constatação reforça a hipótese de que alternativas institucionais podem levar os agricultores familiares (assentados ou dos fluxos agroindustriais tradicionais) a compor efetivamente a agenda política local. Nesse sentido, discorre sobre os programas municipais de Araraquara-SP, centralizados sob a gestão da Coordenadoria de Agroindústria e Segurança Alimentar e mostra que tais iniciativas podem ser consideradas como um embrião de modelo de desenvolvimento alternativo às economias regionais, capaz de alterar, com ganho qualitativo, padrões de segurança alimentar e de responsabilidade social dos municípios, os quais são visivelmente prejudicados com a má distribuição de renda causada pela expansão da cana, com conseqüentes agravantes na qualidade de vida.-------------------The present work analyses the public policies for alimentary security as tools of development in local and regional spaces as a way of improving wealth and job in family agriculture. It shows that institutional mechanisms developed from participative public policies may promote the rural local and regional development with possibilities of social inclusion. Such evidence reinforce the hypothesis that institutional alternatives can lead family farmers (settled or from traditional and agroindustrial streams) to be effectively part of the local political agenda. In this regard, it reasons about the municipal programs of Araraquara-SP, centralized under the administration of the Agroindustry and Alimentary Security Cabinet and it shows that such initiatives can be considered as an embryo of alternative development model to the regional economies, capable of changing, with qualitative gain, standards of alimentary security and of social responsaility of municipal districts which are clearly impaired by poor wealth distribution caused by sugarcane expansion, with aggravating consequences to life quality.

Particular emphasis is laid on the role of algebraic fusion of the matrix generators of the Reflection Equation Algebras. The fusion is shown to induce transitions among D-brane configurations admitting an interpretation in terms of RG-driven condensation phenomena.

description: Generalized mode-coupling theory (GMCT) constitutes a systematically correctable, first-principles theory to study the dynamics of supercooled liquids and the glass transition. It is a hierarchical framework that, through the incorporation of increasingly many particle density correlations, can remedy some of the inherent limitations of the ideal mode-coupling theory (MCT). However, despite MCT's limitations, the ideal theory also enjoys several remarkable successes, notably including the analytical scaling laws for the $α$- and $β$-relaxation dynamics. Here we mathematically derive similar scaling laws for arbitrary-order multi-point density correlation functions obtained from GMCT under arbitrary mean-field closure levels. More specifically, we analytically derive the asymptotic and preasymptotic solutions for the long-time limits of multi-point density correlators, the critical dynamics with two power-law decays, the factorization scaling laws in the $β$-relaxation regime, and the time-density superposition principle in the $α$-relaxation regime. The two characteristic power-law-divergent relaxation times for the two-step decay and the non-trivial relation between their exponents are also obtained. The validity ranges of the leading-order scaling laws are also provided by considering the leading preasymptotic corrections. Furthermore, we test these solutions for the Percus-Yevick hard-sphere system. We demonstrate that GMCT preserves all the celebrated scaling laws of MCT while quantitatively improving the exponents, rendering the theory a promising candidate for an ultimately quantitative first-principles theory of glassy dynamics.

description: It is shown that Einstein-Rosen bridges (wormholes) hypothetical objects that topologically connect separate locations in the Universe can be static solutions of the Einstein equations. The corresponding equations for bridges are reduced to a form convenient for their analysis and numerical solution. The matter forming the bridge must have a sufficiently hard and anisotropic equation of state. Our results are compared with a previously known analytic solution for a bridge, which is a special case of the general solution in the framework of general relativity. The deflection of photons by the bridge (gravitational lensing) is studied.

description: We report on Chandra ACIS and XMM-Newton MOS/PN imaging observations of two pulsar wind nebulae (K3/PSR J1420-6048 and G313.3+0.1=`the rabbit') associated with the Galactic unidentified gamma-ray source GeV J1417-6100. With the excellent ACIS imaging, the very energetic pulsar PSR J1420-6048 is separated from its surrounding nebula. This nebula has surprisingly little compact structure, although a faint arc is seen near the pulsar. Similarly, two point sources are resolved in the rabbit nebula. The large XMM-Newton collecting area provides useful spectral constraints on the rabbit and the associated point sources. Based on spectra and X-ray morphology, we identify one point source as a plausible pulsar counterpart. Large backgrounds and low source counts limited pulse search sensitivities, but we report pulse upper limits and a candidate 108ms period for the rabbit pulsar based on the XMM-Newton data and an ACIS CC observation. Comparison of the X-ray images with high resolution ATCA radio maps shows that the non-thermal X-ray emission corresponds well with the radio structure.

description: We revisit an inequality due to Onsager, which states that the (quantum) liquid structure factor has an upper bound of the form (const.) x |k|, for not too large modulus of the wave vector k. This inequality implies the validity of the Landau criterion in the theory of superfluidity with a definite, nonzero critical velocity. We prove an auxiliary proposition for general Bose systems, together with which we arrive at a rigorous proof of the inequality for one of the very few soluble examples of an interacting Bose fluid, Girardeau's model. The latter proof demonstrates the importance of the thermodynamic limit of the structure factor, which must be taken initially at k different from 0. It also substantiates very well the heuristic density functional arguments, which are also shown to hold exactly in the limit of large wave-lengths. We also briefly discuss which features of the proof may be present in higher dimensions, as well as some open problems related to superfluidity of trapped gases.

Modeling paper machine cross direction slice lip responses close to sheet edges
Creators: name: Yang, David Wei
Publisher: name: University of British Columbia
Year: 2009

description: The design of paper machine cross directional (CD) control systems is normally based on actuator response models obtained in the centre rather than the machine edges. However process characteristics near the sheet edges are different from those in the centre of the sheet. Even with good CD control, the edge profile often shows the greatest variations from the target level. The application of control algorithms more suited to the centre of the machine reduces controller effectiveness at sheet edges. Control close to the sheet edge is normally carried out using a variety of assumptions concerning the expected response, however, these assumptions are often made for mathematical convenience rather than on the basis of physical principles. This work involves the comparison of edge response of the cross directional slice lip actuators with the response at the centre of the paper machine. The performance of a typical industrial CD actuator centre response model is tested and found to be inadequate when modeling the edge response. A new physical model, using surface wave theory of the slurry is investigated, tested and later modified in an attempt to better model the edge response. The new edge model is found to generate an improved edge response prediction, based on the centre response, but in general will be computationally expensive. Several variants of the proposed model are put to the test and one particular model with a fixed parameter is proposed, based on physical principles to replace the centre model when modeling the edge response of heavy grade papers. The performance of this new model is evaluated and found to be more effective at modeling edge response than the conventional model. In addition, this edge model can be applied in conjunction with typical industrial control software without difficulty. Superposition and linearity in actuator response are successfully evaluated and found to hold for the test responses.

description: Modern deep neural networks are often too large to use in many practical scenarios. Neural network pruning is an important technique for reducing the size of such models and accelerating inference. Gibbs pruning is a novel framework for expressing and designing neural network pruning methods. Combining approaches from statistical physics and stochastic regularization methods, it can train and prune a network simultaneously in such a way that the learned weights and pruning mask are well-adapted for each other. It can be used for structured or unstructured pruning and we propose a number of specific methods for each. We compare our proposed methods to a number of contemporary neural network pruning methods and find that Gibbs pruning outperforms them. In particular, we achieve a new state-of-the-art result for pruning ResNet-56 with the CIFAR-10 dataset.

description: Highly smooth and c-axis oriented superconducting MgB2 thin films were prepared by pulsed laser deposition (PLD) with off-axis geometry. The films were deposited on Al2O3-C substrates perpendicularly aligned to a stoichiometric MgB2 target in a 120 mTorr high purity Ar background gas. An in situ annealing was carried out at 650C for 1 min in a 760 Torr Ar atmosphere. Despite the short annealing time, an x-ray theta-2 theta scan shows fairly good crystallization, according to the clear c-axis oriented peaks for the films. Both atomic force microscopy and the x-ray diffraction results indicate that the crystallite size is less than 50nm. The root mean square roughness of our off-axis film is ~4 nm in a 5x5 square micron area. The Tc onset value of the best off-axis film reaches 33.1 K with a narrow transition width of 0.9 K. The films showed no anisotropy in Hc2-T curves when parallel and perpendicular fields were applied. The slope of Hc2-T curves in low field regime is 1 T/K, which is among the highest reported values.

description: We consider a general class of scalar tensor theories in three dimensions whose action contains up to second-order derivatives of the scalar field with coupling functions that only depend on the standard kinetic term of the scalar field, thus ensuring the invariance under the constant shift of the scalar field. For this model, we show that the field equations for a stationary metric ansatz together with a purely radial scalar field can be fully integrated. The kinetic term of the scalar field solution is shown to satisfy an algebraic relation depending only on the coupling functions, and hence is constant while the metric solution is nothing but the BTZ metric with an effective cosmological constant fixed in terms of the coupling functions. As a direct consequence the thermodynamics of the solution is shown to be identical to the BTZ one with an effective cosmological constant, despite the presence of a scalar field. Finally, the expression of the semi-classical entropy of this solution is also confirmed through a generalized Cardy-like formula involving the mass of the scalar soliton obtained from the black hole by means of a double Wick rotation.

description: O objetivo deste trabalho é o cálculo da sustentabilidade de propriedades produtoras de soja, algodão e de cana-de-açúcar no Estado de Goiás, com base nos dados da safra 2006/07. Como a produção de cana-de-açúcar em Goiás apresentou crescimento expressivo nos últimos anos, questiona-se a relação desta cultura com as de soja e algodão. A análise será efetuada com base nos custos totais de produção, em nível de propriedade e não apenas de culturas isoladamente, cujos dados foram obtidos em coletas primárias de dados, através da técnica de painel. Os dados de soja e algodão são do estado de Goiás, para três grandes regiões, e os de cana-de-açúcar, da região oeste de São Paulo. Os resultados apontaram para rentabilidade positiva sobre os custos operacionais, mas retornos negativos sobre o custo total. Assim, as propriedades podem não ser sustentáveis no longo prazo. A cana-de-açúcar foi a cultura com o menor retorno de investimento em relação ao algodão e a soja. Além disso, o algodão foi a cultura mais rentável em duas das três propriedades analisadas, enquanto que a soja mostrou-se mais atrativa em apenas um dos três casos.---------------------------This work aims to calculate the sustainability of growing soybean, cotton and sugar cane in farms of Goiás State in the year of 2006/07. As the production of sugar cane in Goiás is rising in the last years, the introduction of this culture in the state has being questioned. The analysis will be done on the basis of total production costs in the farm, not just with the cultures separately. Data of soybean and cotton were taken from Goiás, which was shared in three great regions. Data of sugar cane was collected in Sao Paulo state. Results have pointed to positive returns on the operational costs, but negative returns on the total cost. Thus, the properties can not be sustainable in a long period. Sugar cane was the culture with worst return of investment in relation to cotton and soybean. Moreover, cotton had the best results in two of three analyzed properties, while soybean was more attractive in only one of the three cases.
Measurement of Prompt Photon Cross Sections in Photoproduction at HERA

description: Results are presented on the photoproduction of isolated prompt photons, inclusively and associated with jets, in the gamma p center of mass energy range 142 < W < 266 GeV. The cross sections are measured for the transverse momentum range of the photons 5 < E_T^gamma < 10 GeV and for associated jets with E_T^jet > 4.5 GeV. They are measured differentially as a function of E_T^gamma, E_T^jet, the pseudorapidities eta^gamma and eta^jet and estimators of the momentum fractions x_gamma and x_p of the incident photon and proton carried by the constituents participating in the hard process. In order to further investigate the underlying dynamics, the angular correlation between the prompt photon and the jet in the transverse plane is studied. Predictions by perturbative QCD calculations in next to leading order are about 30% below the inclusive prompt photon data after corrections for hadronisation and multiple interactions, but are in reasonable agreement with the results for prompt photons associated with jets. Comparisons with the predictions of the event generators PYTHIA and HERWIG are also presented.

description: In the context of matrix displacement decomposition, Bozzo and Di Fiore introduced the so-called $τ_{\varepsilon,φ}$ algebra, a generalization of the more known $τ$ algebra originally proposed by Bini and Capovani. We study the properties of eigenvalues and eigenvectors of the generator $T_{n,\varepsilon,φ}$ of the $τ_{\varepsilon,φ}$ algebra. In particular, we derive the asymptotics for the outliers of $T_{n,\varepsilon,φ}$ and the associated eigenvectors; we obtain equations for the eigenvalues of $T_{n,\varepsilon,φ}$, which provide also the eigenvectors of $T_{n,\varepsilon,φ}$; and we compute the full eigendecomposition of $T_{n,\varepsilon,φ}$ in the specific case $\varepsilonφ=1$. We also present applications of our results in the context of queuing models, random walks, and diffusion processes, with a special attention to their implications in the study of wealth/income inequality and portfolio dynamics.
Ground State and Tkachenko Modes of a Rapidly Rotating Bose-Einstein Condensate in the Lowest Landau Level State

description: The Letter considers the ground state and the Tkachenko modes for a rapidly rotating Bose-Einstein condensate (BEC), when its macroscopic wave function is a coherent superposition of states analogous to the lowest Landau levels of a charge in a magnetic field. As well as in type II superconductors close to the critical magnetic field $H_{c2}$, this corresponds to a periodic vortex lattice. The exact value of the shear elastic modulus of the vortex lattice, which was known from the old works on type II superconductors, essentially exceeds the values calculated recently for BEC. This is important for comparison with observation of the Tkachenko mode in the rapidly rotating BEC.

description: In this work, we deal with the chiral string model for which the world-sheet current is null in the framework of a scalar-tensor gravity. Our main goal is to analyse the impact of such a current on the gravitational macroscopic effects. For the purpose of this analysis, we first study the gravitational properties of the spacetime generated by this string in the presence of a dilaton field. Then, we carry out an investigation of the mechanism of formation and evolution of wakes in this framework, showing the explicit contribution of the chirality to this effect.

subject: FOS: Physical sciences

description: We report a new theoretical method for X-ray absorption spectroscopy (XAS) in condensed matter which is based on the multi-channel multiple scattering theory of Natoli et al. and the eigen-channel R-matrix method. While the highly flexible real-space multiple scattering (RSMS) method guarantees a precise description of the single-electron part of the problem, multiplet-like electron correlation effects between the photo-electron and localized electrons can be taken account for in a configuration interaction scheme. For the case where correlation effects are limited to the absorber atom, a technique for the solution of the equations is devised, which requires only little more computation time than the normal RSMS method for XAS. The new method is described and an application to XAS at the Ca $L_{2,3}$-edge in bulk Ca, CaO and CaF$_2$ is presented.

description: The dynamics of fluid-matter under the influence of gravitomagnetic fields are formulated and solved for the case of fully developed turbulence. Gravitomagnetic effects reduce the vortical complexity and nonlinearity of turbulence, even leading to its extinction within large volumes, and generate departures from Kolmogorov turbulence scalings, that are explained via a combination of dimensional and exact analysis arguments.

description: Let $U^{n}$ be the unit polydisc of ${\Bbb C}^{n}$ and $ϕ=(ϕ_1, >..., ϕ_n)$ a holomorphic self-map of $U^{n}.$ By ${\cal B}^p(U^{n})$, ${\cal B}^p_{0}(U^{n})$ and ${\cal B}^p_{0*}(U^{n})$ denote the $p$-Bloch space, Little $p$-Bloch space and Little star $p$-Bloch space in the unit polydisc $U^n$ respectively, where $p, q>0$. This paper gives the estimates of the essential norms of bounded composition operators $C_ϕ$ induced by $ϕ$ between ${\cal B}^p(U^n)$ (${\cal B}^p_{0}(U^n)$ or ${\cal B}^p_{0*}(U^n)$) and ${\cal B}^q(U^n)$ (${\cal B}^q_{0}(U^n)$ or ${\cal B}^q_{0*}(U^n)$). As their applications, some necessary and sufficient conditions for the bounded composition operators $C_ϕ$ to be compact from ${\cal B}^p(U^n)$ $({\cal B}^p_{0}(U^n)$ or ${\cal B}^p_{0*}(U^n))$ into ${\cal B}^q(U^n)$ (${\cal B}^q_{0}(U^n)$ or ${\cal B}^q_{0*}(U^n)$) are obtained.

description: The purpose of this paper is to describe a method for determining a cooling template for galaxies, using nearby galaxies, and applicable to future observations of distant galaxies. We observed two starburst galaxies (NGC 253 and Henize 2-10) with the Caltech Submillimeter Observatory in the rotational lines of carbon monoxide 12CO(J=3-2), (J=6-5) and (J=7-6) for both, and also 12CO(J=4-3) and 13CO(J=3-2) for Henize 2-10 and in the 3P2-3P1 fine-structure transitions of atomic carbon [CI] at 809 GHz for NGC 253. Some of these observations have been made previously, but the present multitransition study (including data found in the literature) is the most complete to date for the two galaxies. From these observations, we have derived the properties of the warm and dense molecular gas in the galaxy nuclei. We used an LTE analysis and an LVG radiative transfer model to determine physical conditions of the interstellar medium in both sources and predicted integrated line properties of all CO transitions up to 12CO(15-14). A PDR model has also been used and here the data are well fitted (within 20 %) by a model cloud with a gas density of n(H)= 8.0 +- 1.0 * 10E5 cm-3 and an incident FUV flux of chi = 20000 for Henize 2-10. For NGC 253, we deduced n(H) = 3.0 +- 0.5 * 10E5 cm-3 and chi = 20000 for the modelled cloud. The physical properties of warm gas and CO cooling curves of the target galaxies are compared with those measured for the nucleus of the Milky Way and the Cloverleaf QSO. The gas properties and CO cooling curve are similar for the two starburst galaxies and the Cloverleaf QSO while the Milky Way nucleus exhibits lower excitation molecular gas.

Social workers’ experiences of being cared for by their clients
Creators: name: Alexander, Carla Elizabeth
Publisher: name: University of British Columbia
Year: 2009

description: The focus of this study is the experience of participating social workers of being cared for by their clients. The findings suggest several theoretical propositions that may be applied to enhance the way in which social work articulates the professional social worker-client relationship. Participants describe the nature of this enhancement as an increased awareness and appreciation of the potential benefits to both clients and themselves when they are open to receiving the care that a client may choose to offer. Further, the context of the professionalization of the social worker-client relationship plays a significant role in making this openness to giving and receiving care or engaging in reciprocal relationships a subversive activity for social workers. The summary propositions are grounded in both the analysis of the experiences described by practicing social workers and contemporary cultural human development theory.

description: O presente trabalho tem como objetivo caracterizar a oferta dos produtores de hortaliças nas micro-bacias Bandeira e Segredo na cidade de Campo Grande – MS. Para o desenvolvimento deste estudo foi adotado o método indutivo e utilizado dados secundários do IBGE, CEASA/MS, e primários obtidos com a pesquisa de campo junto aos produtores rurais. A partir destas informações procedeu-se uma análise dos atributos transacionais presentes nas negociações dos produtores. Constatou-se que estes têm carência de informações e dificuldade de união, o que dificulta o poder de barganha tanto para compra de insumos quanto para venda das hortaliças.-------------------This work aims to characterize the offer producers of vegetables in the micro-basins Bandeira and Segredo in the city of Campo Grande - MS. For the development of this study was adopted and the inductive method used data side of the IBGE, CEASA / MS, and the primary obtained with a search field. Since this information has to be a transactional analysis of the attributes of producers in the negotiations. It appeared that they have lack of information and difficulty in union, which hinders the power to bargain both for purchasing inputs and for sale of vegetables.

description: Este estudo apresenta uma análise da exportação brasileira de melões através da verificação das séries volume exportado, preço doméstico e taxa de câmbio utilizando a metodologia VAR, no período de janeiro de 1996 a março de 2007. As séries estudadas eram nãoestacionárias e, por isso optou-se pela utilização do conceito de co-integração. No entanto, o número de vetores de co-integração foi igual ao número de variáveis do modelo e por isso, utilizou-se o modelo Vetorial Auto Regressivo – VAR em nível. A decomposição da variância dos erros de previsão indicou que após choque não antecipado sobre as variáveis, a maior parte do seu comportamento ao longo do tempo continua sendo explicado pela própria variável.---------------------This study presents an analysis of the Brazilian export of melons through the verification of the series exported volume, domestic price and exchange rate using the methodology VAR, in the period of January of 1996 to March of 2007. The studied series were no-stationary and opted for the use of the co-integration concept. However, the number of co-integration vectors was equal to the number of variables of the model and then, the model Vectorial Regressive was used–VAR in level. The decomposition of the variance of the forecast mistakes indicated that after non premature shock on the variables, most of its behavior along the time continues being explained by the own variable.

description: In this paper, we report the applicability of the density matrix renormalization group(DMRG) approach to the cylindrical single wall carbon nanotube (SWCN) for purpose of its correlation effect. By applying the DMRG approach to the $t$+$U$+$V$ model, with $t$ and $V$ being the hopping and Coulomb energies between the nearest neighboring sites, respectively, and $U$ the onsite Coulomb energy, we calculate the phase diagram for the SWCN with chiral numbers ($n_{1}=3, n_{2}=2$), which reflects the competition between the correlation energy $U$ and $V$. Within reasonable parameter ranges, we investigate possible correlated groundstates, the lowest excitations and the corresponding correlation functions in which the connection with the excitonic insulator is particularly addressed.
