description: We present a Monte-Carlo calculation of the microcanonical ensemble of the of the ideal hadron-resonance gas including all known states up to a mass of about 1.8 GeV and full quantum statistics. The microcanonical average multiplicities of the various hadron species are found to converge to the canonical ones for moderately low values of the total energy, around 8 GeV, thus bearing out previous analyses of hadronic multiplicities in the canonical ensemble. The main numerical computing method is an importance sampling Monte-Carlo algorithm using the product of Poisson distributions to generate multi-hadronic channels. It is shown that the use of this multi-Poisson distribution allows an efficient and fast computation of averages, which can be further improved in the limit of very large clusters. We have also studied the fitness of a previously proposed computing method, based on the Metropolis Monte-Carlo algorithm, for event generation in the statistical hadronization model. We find that the use of the multi-Poisson distribution as proposal matrix dramatically improves the computation performance. However, due to the correlation of subsequent samples, this method proves to be generally less robust and effective than the importance sampling method.

description: Autonomic computing has been proposed recently as a way to address the difficult management of applications whose complexity is constantly increasing. Autonomous applications will have to be especially flexible and be able to monitor themselves permanently. This work presents a framework, Pandora, which eases the construction of applications that satisfy this double goal. Pandora relies on an original application programming pattern - based on stackable layers and message passing - to obtain minimalist model and architecture that allows to control the overhead imposed by the full reflexivity of the framework. Besides, a prototype of the framework has been implemented in C++. A detailed performance study, together with examples of use, complement this presentation

Making an analogy between a multi chain interaction in charge density wave transport and the use of wavefunctionals to form soliton- anti soliton pairs

description: A numerical simulation shows that a massive Schwinger model used to formulate solutions to charge density wave (CDW) transport is insufficient for transport of soliton- anti soliton pairs through a pinning gap model of CDW transport. However, a model Hamiltonian with Peierls condensation energy used to couple adjacent chains (or transverse wave vectors) permits formation of soliton - anti soliton pairs that could be used to transport CDW through a potential barrier. There are analogies between this construction and the false vacuum hypothesis used for showing a necessary and sufficient condition for wave functionals for formation of soliton - anti soliton pairs. This can be established by either use of the Bogomol'nyi inequality or through an experimental artifact resulting through use of the false vacuum hypothesis to obtain a proportional distance between the soliton - anti soliton pair charge centers

description: Realising strong photon-photon interactions in a solid-state setting is a major goal with far reaching potential for optoelectronic applications. Using Landau's quasiparticle framework combined with a microscopic many-body theory, we explore the interactions between exciton-polaritons and trions in a two-dimensional semiconductor injected with an electron gas inside a microcavity. We show that particle-hole excitations in the electron gas mediate an attractive interaction between the polaritons, whereas a trion-polariton interaction mediated by the exchange of an electron is either repulsive or attractive depending on the specific polariton branch. These mediated interactions are intrinsic to the quasiparticles and are also present in the absence of light. Importantly, they can be tuned to be more than an order of magnitude stronger than the direct polariton-polariton interaction in the absence of the electron gas, thereby providing a promising outlook for non-linear optical components. Finally, we compare our theoretical predictions with two recent experiments.

Trata-se de uma reflexão sobre as teorias que subjugaram a agricultura familiar como um modo de produção fadado ao desaparecimento. As transformações ocorridas na forma de acumulação e centralização do capital nas últimas décadas não permitem mais tratar a pequena produção como algo isolado, mas como objeto fundamental de uma nova proposta de desenvolvimento. A primeira parte desse trabalho trata dos aspectos relacionados aos conceitos e teorias que desvendam a identidade e as peculiaridades da agricultura familiar frente ao sistema capitalista. A segunda parte faz uma análise do sistema capitalista e a forma como ele vem se apropriando do capital sob a ótica do neoliberalismo. Dessa forma, repensar a sua lógica de produção é reconhecê-la como uma estratégia para a superação de vários estrangulamentos econômicos e sociais nos quais a sociedade contemporânea está inserida.--------------------------------------------------------This article discuss the inherent contradictions between small and big agricultural production. It is a reflection about the theories that have subjugated familiar agriculture as a way of production bound to disappear. The transformations occurred in the form of capital accumulation and centralization in the late decades does not allow the treat of small production as something isolated anymore, but as a prime object of a new development proposal. The first part of the essay talks about aspects linked to concepts and theories the show up an identity and the peculiarities of familiar agriculture before the capitalist system. The second part is about a capitalist system analysis and the way how it has been appropriating the capital under the neoliberalism view. So, thinking again its production logic brings knowledge to overcome many economic and social problems which the actual society is living.

description: The origin of radio relics is usually explained via diffusive shock acceleration (DSA) or re-acceleration of electrons at/from merger shocks in galaxy clusters. The case of acceleration is challenged by the low predicted efficiency of low-Mach number merger shocks, unable to explain the power observed in most radio relics. In this Letter we present the discovery of a new giant radio relic around the galaxy cluster Abell 2249 ($z=0.0838$) using LOFAR. It is special since it has the lowest surface brightness of all known radio relics. We study its radio and X-ray properties combinig LOFAR data with uGMRT, JVLA and XMM. This object has a total power of $L_{1.4\rm GHz}=4.1\pm 0.8 \times 10^{23}$ W Hz$^{-1}$ and integrated spectral index $α= 1.15\pm 0.23$. We infer for this radio relic a lower bound on the magnetisation of $B\geq 0.4\, μ$G, a shock Mach number of $\mathcal{M}\approx 3.79$, and a low acceleration efficiency consistent with DSA. This result suggests that a missing population of relics may become visible thanks to the unprecedented sensitivity of the new generation of radio telescopes.

description: We present the numerically exact ground state energy, effective mass, and isotope exponents of a one-dimensional lattice polaron, valid for any range of electron-phonon interaction, applying a new continuous-time Quantum Monte Carlo (QMC) technique in a wide range of coupling strength and adiabatic ratio. The QMC method is free from any systematic finite-size and finite-time-step errors. We compare our numerically exact results with analytical weak-coupling theory and with the strong-coupling $1/λ$ expansion. We show that the exact results agree well with the canonical Fröhlich and Holstein-Lang-Firsov theories in the weak and strong coupling limits, respectively, for any range of interaction. We find a strong dependence of the polaron dynamics on the range of interaction. An increased range of interaction has a similar effect to an increased (less adiabatic) phonon frequency: specifically, a reduction in the effective mass.

description: Forest products play an important role in supporting rural livelihoods and food security in many developing countries. Pimentel et al. (1997) found that the integrity of forests is vital to world food security, mostly because of the dependence of the poor on forest resources. Studies of the role of forest products in household welfare in Zambia have found that such products are among the top sources of household income in some rural areas. This paper uses statistical analysis to examine the role of non-timber forest products NTFPs) in rural household welfare in Zambia, with two main objectives. First, using rural household survey data, we estimate the share of NTFP income to total household income with the aim of assessing the proportion and distribution of business activities related to NTFPs. Second, we estimate the determinants of rural household participation in the extraction and trade of NTFPs, with an interest in the characteristics of households that are more dependent on forest products for income.

description: To stabilize the non-trivial spin textures, e.g., skyrmions or chiral domain walls in ultrathin magnetic films, an additional degree of freedom such as the interfacial Dzyaloshinskii-Moriya interaction (IDMI) must be induced by the strong spin-orbit coupling (SOC) of a stacked heavy metal layer. However, advanced approaches to simultaneously control IDMI and perpendicular magnetic anisotropy (PMA) are needed for future spin-orbitronic device implementations. Here, we show an effect of atomic-scale surface modulation on the magnetic properties and IDMI in ultrathin films composed of 5d heavy metal/ferromagnet/4d(5d) heavy metal or oxide interfaces, such as Pt/CoFeSiB/Ru, Pt/CoFeSiB/Ta, and Pt/CoFeSiB/MgO. The maximum IDMI value corresponds to the correlated roughness of the bottom and top interfaces of the ferromagnetic layer. The proposed approach for significant enhancement of PMA and IDMI through the interface roughness engineering at the atomic scale offers a powerful tool for the development of the spin-orbitronic devices with the precise and reliable controllability of their functionality.

description: Rural poverty rates in Zambia have remained very high, at 80%, over the past decade and a half, whilst urban poverty rates have declined, from 49% in 1991 to 34% in 2006. Redressing this high rural poverty rate remains a government priority in the National Development Programs. However, solutions have proven elusive. Solid empirically based information on dynamics that have improved the welfare of small-scale farm households in Zambia, combined with an agenda for disseminating this information in public discourse, offer prospects for generating a more transparent and pro-poor policy orientation. Using longitudinal data collected from 4,286 households which participated in three nationwide surveys conducted over seven years, in 2001, 2004, and 2008, we examine the factors associated with chronic and transient poverty and use the results to draw implications for designing policies and programs for alleviating rural poverty and promoting income growth for rural Zambia households.

description: A spatial scale-free network is introduced and studied whose motivation has been originated in the growing Internet as well as the Airport networks. We argue that in these real-world networks a new node necessarily selects one of its neighbouring local nodes for connection and is not controlled by the preferential attachment as in the Barabási-Albert (BA) model. This observation has been mimicked in our model where the nodes pop-up at randomly located positions in the Euclidean space and are connected to one end of the nearest link. In spite of this crucial difference it is observed that the leading behaviour of our network is like the BA model. Defining link weight as an algebraic power of its Euclidean length, the weight distribution and the non-linear dependence of the nodal strength on the degree are analytically calculated. It is claimed that a power law decay of the link weights with time ensures such a non-linear behavior. Switching off the Euclidean space from the same model yields a much simpler definition of the Barabási-Albert model where numerical effort grows linearly with $N$.

description: The dynamics, structure and stability of zonal jets in planetary flows are still poorly understood, especially in terms of coupling with the small-scale turbulent flow. Here, we use an experimental approach to address the questions of zonal jets formation and long-term evolution. A strong and uniform topographic $β$-effect is obtained inside a water-filled rotating tank thanks to the paraboloidal fluid free upper surface combined with a specifically designed bottom plate. A small-scale turbulent forcing is performed by circulating water through the base of the tank. Time-resolving PIV measurements reveal the self-organization of the flow into multiple zonal jets with strong instantaneous signature. We identify a subcritical bifurcation between two regimes of jets depending on the forcing intensity. In the first regime, the jets are steady, weak in amplitude, and directly forced by the local Reynolds stresses due to our forcing. In the second one, we observe highly energetic and dynamic jets of width larger than the forcing scale. An analytical modeling based on the quasi-geostrophic approximation reveals that this subcritical bifurcation results from the resonance between the directly forced Rossby waves and the background zonal flow.

description: Several imputation approaches using a large sample and different levels of censoring are compared and contrasted following a multiple imputation methodology. The study not only discusses these imputation approaches, but also quantifies differences in price variability before and after price imputation, evaluates the performance of each method, and estimates and compares parameters and elasticities from a complete demand system. The study’s findings reveal that small variability among the mean prices from the various imputation approaches may result in relatively larger variability among the underlying parameter estimates of interest and the ultimately desired measures. This suggests that selection bias may be avoided by validating the imputation approaches and choosing the imputation method based on an analysis of the ultimately desired measures.

description: The thermoelectric power S is studied within the one-dimensional Hubbard model using the linear response theory and the numerical exact-diagonalization method for small systems. While both the diagonal and off-diagonal dynamical correlation functions of particle and energy current are singular within the model even at temperature T>0, S behaves regularly as a function of frequency $ω$ and T. Dependence on the electron density n below the half-filling reveals a change of sign of S at n_0=0.73+/-0.07 due to strong correlations, in the whole T range considered. Approaching half-filling S is hole-like and can become large for U>>t although decreasing with T.

description: This paper analyses the horizontal transmission of cereal price shocks both across different market places and across different commodities. The analysis is carried out using Italian and international weekly spot (cash) price data and concentrating the attention on years 2006-2010, a period of generalized exceptional exuberance and consequent rapid drop of agricultural prices. The work aims at investigating how price transmission may be affected during price bubbles. The properties of price time series are firstly explored to assess which data generation process may have eventually produced the observed patterns. Secondly, the interdependence across prices is specified and estimated adopting appropriate cointegration techniques.

description: The demonstration of quantum speedup, also known as quantum computational supremacy, that is the ability of quantum computers to outperform dramatically their classical counterparts, is an important milestone in the field of quantum computing. While quantum speedup experiments are gradually escaping the regime of classical simulation, they still lack efficient verification protocols and rely on partial validation. Here we derive an efficient protocol for verifying with single-mode Gaussian measurements the output states of a large class of continuous-variable quantum circuits demonstrating quantum speedup, including Boson Sampling experiments, thus enabling a convincing demonstration of quantum speedup with photonic computing. Beyond the quantum speedup milestone, our results also enable the efficient and reliable certification of a large class of intractable continuous-variable multimode quantum states.

Homeostatic regulation of growth-associated increase in the labile intracellular pool of zinc in 3T3 cells
Creators: name: Simpson, Madeline
Publisher: name: University of British Columbia
Year: 2009

description: The size of the labile intracellular pool of zinc (LIPZ) is increased during growth factorstimulated proliferation in 3T3 cells, but the mechanisms involved are unknown. We hypothesized that this increase in the size of the LIPZ is the result of altered cellular zinc homeostasis, ensuring an adequate supply of zinc to sustain cell proliferation. The objectives of this study were to study the role of metallothionein (MT), zinc importers (DCT1, ZIP1 and ZIRTL), zinc exporters (ZnT-1, -2, and ZnT-4), and zinc net retention in the proliferationassociated increase in the size of the LIPZ. 3T3 fibroblasts were cultured in Dulbecco's Modified Eagle Media (DMEM) supplemented with 10% fetal bovine serum (FBS) for 72 h (1 x 10⁴/T75; n = 6), followed by induction of quiescence with 1% FBS for 48 h. The cells were then cultured in DMEM supplemented with 10% FBS for 48 h, with or without growth factors [platelet-derived growth factor (100 ng/mL), epidermal growth factor (50 ng/mL), and insulin-like growth factor-1 (20 ng/mL)]. The size of the LIPZ was assessed by relative brightness of Zinquin-dependent fluorescence using a UV fluorescent microscope. Levels of MT were assessed using the ¹⁰⁹Cd-hemoglobin affinity assay. Abundance of transporter mRNA was determined by reverse transcription-polymerase chain reaction. Zinc net retention was determined by incubating cells with ⁶⁵zinc beginning at the time of growth factor treatment. Growth factor treatment increased cell number (48%) and relative brightness of Zinquin-dependent fluorescence, as well as redistributing the LIPZ to the area surrounding the nucleus, but had no effect on total cellular zinc concentration and MT protein levels. Growth factor treatment increased the abundance of DCT1 (27%), ZIRTL (33%), ZnTl (24%) and ZnT4 (67%) mRNA, but did not affect the abundance of ZIP1 and ZnT2 mRNA. Zinc net retention were increased by growth factor treatment at 45 min, 6 and 48 h, but were not affected at 0, 5, 15, 30, and 60 min, and 12 h. These data suggest that the increase in the size of the LIPZ in response to growth stimulation is via increased zinc net retention through selective upregulation of zinc transporter expression, and is likely required for DNA synthesis.

description: Atmospheric retrieval of exoplanets from spectroscopic observations requires an extensive exploration of a highly degenerate and high-dimensional parameter space to accurately constrain atmospheric parameters. Retrieval methods commonly conduct Bayesian parameter estimation and statistical inference using sampling algorithms such as Markov Chain Monte Carlo (MCMC) or Nested Sampling. Recently several attempts have been made to use machine learning algorithms either to complement or replace fully Bayesian methods. While much progress has been made, these approaches are still at times unable to accurately reproduce results from contemporary Bayesian retrievals. The goal of our present work is to investigate the efficacy of machine learning for atmospheric retrieval. As a case study, we use the Random Forest supervised machine learning algorithm which has been applied previously with some success for atmospheric retrieval of the hot Jupiter WASP-12b using its near-infrared transmission spectrum. We reproduce previous results using the same approach and the same semi-analytic models, and subsequently extend this method to develop a new algorithm that results in a closer match to a fully Bayesian retrieval. We combine this new method with a fully numerical atmospheric model and demonstrate excellent agreement with a Bayesian retrieval of the transmission spectrum of another hot Jupiter, HD 209458b. Despite this success, and achieving high computational efficiency, we still find that the machine learning approach is computationally prohibitive for high-dimensional parameter spaces that are routinely explored with Bayesian retrievals with modest computational resources. We discuss the trade offs and potential avenues for the future.

description: We analyze a grid of radiative hydrodynamic simulations of solar flares to study the energy balance and response of the atmosphere to nonthermal electron beam heating. The appearance of chromospheric bubbles is one of the most notable features that we find in the simulations. These pockets of chromospheric plasma get trapped between the transition region and the lower atmosphere as it is superheated by the particle beam. The chromospheric bubbles are seen in the synthetic spectra, appearing as an additional component to Balmer line profiles with high Doppler velocities as high as 200 km/s. Their signatures are also visible in the wings of Ca II 8542A line profiles. These bubbles of chromospheric plasma are driven upward by a wave front that is induced by the shock of energy deposition, and require a specific heating rate and atmospheric location to manifest.

description: We consider one possible implementation of Hadamard gate for optical and ion trap holonomic quantum computers. The expression for its fidelity determining the gate stability with respect to the errors in the single-mode squeezing parameter control is analytically derived. We demonstrate by means of this expression the cancellation of the squeezing control errors up to the fourth order on their magnitude.

Supersymmetry of $\mathcal{PT}$- symmetric tridiagonal Hamiltonians

description: We extend the study of supersymmetric tridiagonal Hamiltonians to the case of non-Hermitian Hamiltonians with real or complex conjugate eigenvalues. We find the relation between matrix elements of the non-Hermitian Hamiltonian $H$ and its supersymmetric partner $H^{+}$ in a given basis. Moreover, the orthogonal polynomials in the eigenstate expansion problem attached to $H^{+}$ can be recovered from those polynomials arising from the same problem for $H$ with the help of kernel polynomials. Besides its generality, the developed formalism in this work is a natural home for using the numerically powerful Gauss quadrature techniques in probing the nature of some physical quantities such as the energy spectrum of $\mathcal{PT}$-symmetric complex potentials. Finally, we solve the shifted $\mathcal{PT}$-symmetric Morse oscillator exactly in the tridiagonal representation.

description: Dust extinction can be determined from the number of distant field galaxies seen through a spiral disk. To calibrate this number for the crowding and confusion introduced by the foreground image, Gonzalez et al.(1998) and Holwerda et al. (2005) developed the ``Synthetic Field Method'' (SFM), which analyses synthetic fields constructed by adding various deep exposures of unobstructed background fields to the candidate foreground galaxy field. The advantage of the SFM is that it gives the average opacity for area of galaxy disk without assumptions about either the distribution of absorbers or of the disk starlight. However it is limited by low statistics of the surviving field galaxies, hence the need to combine a larger sample of fields. This paper presents the first results for a sample of 32 deep HST/WFPC2 archival fields of 29 spirals. The radial profiles of average dust extinction in spiral galaxies based on calibrated counts of distant field galaxies is presented here, both for individual galaxies as well as for composites from our sample. The effects of inclination, spiral arms and Hubble type on the radial extinction profile are discussed. (Abbreviated)

description: Competitiveness and sustainability of the olive-oil sector are strongly associated with the satisfaction of customer demand and preferences towards quality, safety, and environmental issues. In product design and development, Quality Function Deployment (QFD) provides a comprehensive, systematic approach to ensure agrifood products meet or exceed customer expectations. QFD can be a powerful tool because it can reduce time to market, improve quality, and enhance customer satisfaction. Although QFD has been used in the food industry since 1987, no application has been found in the case of olive oil. In this study, after identifying customer needs or requirements of different attributes of quality olive oil, by a survey to 439 respondents to determine preference and consumption behaviour, agricultural practices that optimally satisfy these preferences were determined, through a Quality Function Deployment (QFD) model using expert knowledge. The use of the correlation matrix and then the construction of the "House of Quality" (HOQ), the relative contribution of each of these practices that most satisfy customer needs and desires were designed. These matrices are used to translate higher-level “Whats” or needs into lower-level “Hows” – agronomical practices (technical characteristics) to satisfy these needs. The findings are helpful for designing agricultural policies and marketing strategies to improve sustainability and competitiveness of Spanish olive oil.

description: The specific heat, heat flux (DTA trace) and dielectric constant of KDP ferroelectric crystal have been measured simultaneously for various electric fields with a conduction calorimeter. The specific heat presents a strong anomaly but these simultaneous measurements allow us to evaluate the latent heat accurately. Latent heat decreases with field and the value of critical electric field --that where latent heat disappears-- is estimated to be (0.44\pm0.03) kV/cm. Incidentally, we have measured simultaneously the dielectric permittivity which suggests that latent heat is developed as domains are growing.
