description: O aumento do consumo de alimentos teve um grande aumento nos últimos anos, conforme Pesquisa de Orçamentos Familiares (POF). As informações passam a ser uma ferramenta de auxilio aos indivíduos na escolha de suas refeições (fora de casa). O objetivo principal do presente estudo é analisar a disponibilidade de informações nutricionais. Especificamente, retende-se: a) averiguar as bases legais em relação à informação em restaurantes comerciais sobre as características dos alimentos; b) analisar sua importância para os consumidores; c) verificar se a informação nutricional influencia no processo de escolha dos restaurantes; e d) verificar os benefícios e obstáculos para oferecer a informação nutricional necessária aos consumidores. Os procedimentos metodológicos utilizados para alcançar os objetivos do artigo: a) pesquisa bibliográfica, baseada em livros, artigos e dissertações recentes, além da regulamentação da Agência Nacional de Vigilância Sanitária (ANVISA); e b) estudo qualitativo junto a três restaurantes localizados em Campo Grande-MS, cada um correspondendo a uma das seguintes categorias: self-service, à la carte e fast-service. Foi utilizada a técnica de coleta de entrevista individual em profundidade, com um proprietário ou gerente e três clientes de cada restaurante selecionado, perfazendo um total de 12 entrevistados. Na fase de análise, a técnica usada foi análise de conteúdo. Os resultados mostram que as informações sobre os fatores de risco, custo e atratividade por parte dos proprietários e de risco e credibilidade para dos clientes são importantes. Mostram, ainda, que o fato de os clientes terem acesso às informações nutricionais não é fator de risco aos restaurantes, mas sim um ponto de credibilidade, firmando um compromisso com os consumidores em relação aos cuidados com a saúde e a responsabilidade social.

description: High-dynamic-range (HDR) photography involves fusing a bracket of images taken at different exposure settings in order to compensate for the low dynamic range of digital cameras such as the ones used in smartphones. In this paper, a method for automatically selecting the exposure settings of such images is introduced based on the camera characteristic function. In addition, a new fusion method is introduced based on an optimization formulation and weighted averaging. Both of these methods are implemented on a smartphone platform as an HDR app to demonstrate the practicality of the introduced methods. Comparison results with several existing methods are presented indicating the effectiveness as well as the computational efficiency of the introduced solution.

description: Neutron stars provide ideal astrophysical laboratories for probing new physics beyond the Standard Model. If axions exist, photons can develop linear polarization during photon-axion conversion in the magnetic field of a neutron star. We find that the plasma in the neutron star magnetosphere could dramatically enhance the polarization through the resonant conversion effect. With the polarization measurements from PSR B0656+14, 4U 0142+61, and the benchmark polarization measurement in the mid-infrared band, we demonstrate that optical and infrared polarization from neutron stars can provide strong constraints on the axion-photon coupling over a broad axion mass range $10^{-11}\lesssim m_a \lesssim 10^{-3}$ eV.

description: The aim of this paper is to analyze the patterns of technological innovation of the pesticide industry in Brazil in order to suggest industrial policies to reinforce the firm’s competitiveness. The database is based on micro-data of the Technological Innovation Survey (PINTEC) and the Yearly Industrial Survey (PIA) of the Brazilian Statistical and Geography Bureau (IBGE) in 2005. Based on this database the Brazilian industrial firms were classified into four categories according to their innovative capacity. The main results show the existence of multinational subsidiaries as technological leaders and follower firms, composed by national firms, which have reduced R&D capabilities, focusing less technology-intensive products

description: We study the quantum dynamics of a BEC condensate trapped in a double-well potential with a rising interwell barrier. We analytically find the characteristic time scales of the splitting process and compare our results with numerical analyses available in the literature. In first stage of the dynamics, the condensate follows adiabatically the rising of the interwell barrier. At a critical time $t_{ad}$, small amplitude fluctuations around the average trajectory increase exponentially fast, signaling the break-down of adiabaticity. We have found a highly non-trivial dependence of the dephasing time $t_D$, defined by $σ_ϕ(t_D)=1$, where $σ_ϕ(t)$ is the dynamical quantum phase spreading, on $t_{ad}$ and on the ramping time of the interwell barrier.

description: We present a computation of the coherent state path integral for a generic linear system using ``functional methods'' (as opposed to discrete time approaches). The Gaussian phase space path integral is formally given by a determinant built from a first-order differential operator with coherent state boundary conditions. We show how this determinant can be expressed in terms of the symplectic transformation generated by the (in general, time-dependent) quadratic Hamiltonian for the system. We briefly discuss the conditions under which the coherent state path integral for a linear system actually exists. A necessary -- but not sufficient -- condition for existence of the path integral is that the symplectic transformation generated by the Hamiltonian is (unitarily) implementable on the Fock space for the system.

description: It is well-known that the interaction between passivated nanoparticles can be tuned by their complete immersion in a chosen solvent, such as water. What remains unclear on a molecular level is how nanoparticle interactions may be altered in the presence of solvent vapor where complete immersion is not achieved. In this paper, we report an all-atom molecular dynamics simulation study of the change in pair potential of mean force between dodecane thiol ligated gold nanoparticles (AuNPs) when exposed to water vapor. With the equilibrium vapor pressure of water at 25 \degree C, there is very rapid condensation of water molecules onto the surface of the AuNPs in the form of mobile clusters of 100-2000 molecules that eventually coalesce into a few large clusters. When the distance between two AuNPs decreases, a water cluster bridging them provides an adhesive force that increases the depth and alters the shape of the pair-potential of mean force. That change of shape includes a decreased curvature near the minimum, consistent with experimental data showing that cyclic exposure to water vapor and its removal reversibly decreases and increases the Young's modulus of a freely suspended self-assembled monolayer of these AuNPs.

description: Understanding citizens' values in participatory systems is crucial for citizen-centric policy-making. We envision a hybrid participatory system where participants make choices and provide motivations for those choices, and AI agents estimate their value preferences by interacting with them. We focus on situations where a conflict is detected between participants' choices and motivations, and propose methods for estimating value preferences while addressing detected inconsistencies by interacting with the participants. We operationalize the philosophical stance that "valuing is deliberatively consequential." That is, if a participant's choice is based on a deliberation of value preferences, the value preferences can be observed in the motivation the participant provides for the choice. Thus, we propose and compare value preferences estimation methods that prioritize the values estimated from motivations over the values estimated from choices alone. Then, we introduce a disambiguation strategy that combines Natural Language Processing and Active Learning to address the detected inconsistencies between choices and motivations. We evaluate the proposed methods on a dataset of a large-scale survey on energy transition. The results show that explicitly addressing inconsistencies between choices and motivations improves the estimation of an individual's value preferences. The disambiguation strategy does not show substantial improvements when compared to similar baselines--however, we discuss how the novelty of the approach can open new research avenues and propose improvements to address the current limitations.

description: Photo-induced charge transfer of positive and negative charges across the interface between an ordered organic semiconductor and a polymeric insulator is observed in the field-effect experiments. Immobilization of the transferred charge in the polymer results in a shift of the field-effect threshold of polaronic conduction along the interface in the semiconductor, which allows for direct measurements of the charge transfer rate. The transfer occurs when the photon energy exceeds the absorption edge of the semiconductor. The direction of the transverse electric field at the interface determines the sign of the transferred charge; the transfer rate is controlled by the field magnitude and light intensity.

Prospects for Quantum Enhancement with Diabatic Quantum Annealing

description: We assess the prospects for algorithms within the general framework of quantum annealing (QA) to achieve a quantum speedup relative to classical state of the art methods in combinatorial optimization and related sampling tasks. We argue for continued exploration and interest in the QA framework on the basis that improved coherence times and control capabilities will enable the near-term exploration of several heuristic quantum optimization algorithms that have been introduced in the literature. These continuous-time Hamiltonian computation algorithms rely on control protocols that are more advanced than those in traditional ground-state QA, while still being considerably simpler than those used in gate-model implementations. The inclusion of coherent diabatic transitions to excited states results in a generalization called diabatic quantum annealing (DQA), which we argue for as the most promising route to quantum enhancement within this framework. Other promising variants of traditional QA include reverse annealing and continuous-time quantum walks, as well as analog analogues of parameterized quantum circuit ansatzes for machine learning. Most of these algorithms have no known (or likely to be discovered) efficient classical simulations, and in many cases have promising (but limited) early signs for the possibility of quantum speedups, making them worthy of further investigation with quantum hardware in the intermediate-scale regime. We argue that all of these protocols can be explored in a state-of-the-art manner by embracing the full range of novel out-of-equilibrium quantum dynamics generated by time-dependent effective transverse-field Ising Hamiltonians that can be natively implemented by, e.g., inductively-coupled flux qubits, both existing and projected at application scale.

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: We investigate the dephasing of mesoscopic interferences by electron-electron interactions in a strictly one-dimensional geometry composed of two weakly-coupled (clean and very long) Luttinger liquids. The main goal of this paper is to demonstrate that interactions in one dimension can produce a visible attenuation of Aharonov-Bohm oscillations. Through a Nyquist noise type description of the interactions and a direct (exact) calculation based on the Luttinger theory, in our setup we firmly emphasize that the dephasing time results from the electron fractionalization time.

The methodological procedures involved the review of legislation, the verification of participation and the extent of concentration of pensions in rural income distribution after exposure of Law 8213/91 and debate in the literature. It uses the decomposition of the Gini index to measure income distribution, based on microdata from PNAD 1988 to 2008. The survey results have revealed that there was a reduction in the income concentration, from 0.559 in 1988 to 0.498 in 2008, partly explained by changes in the rural labor market (main job) and the rising value of the real minimum wage between 1994 and 2004. However, income derived from pensions rural proved concentrated, which Gini index was 0.417 in 1988 and 0.569 in 2008

description: End users positive response is essential for the success of any software. This is true for both commercial and Open Source Software (OSS). OSS is popular not only because of its availability, which is usually free but due to the user support it provides, generally through public platforms. The study model of this research establishes a relationship between OSS user support and available support tools. To conduct this research, we used a dataset of 100 OSS projects in different categories and examined five user support tools provided by different OSS projects. The results show that project trackers, user mailing lists, and updated versions have a significant role in gaining user support. However, we were unable to find a significant association between user support and documentation, as well as between user support and the troubleshooting guidelines provided by OSS projects.

description: Detection of scattered light can determine the susceptibility of dielectrics. Such imaging normally holds Rayleigh's limit: details finer than the wavelength of the incident light cannot be determined from the far-field zone. We show that time-modulation of an inhomogeneous dielectric can be used to determine its susceptibility. To this end, we focus on the inverse quantum optics problem for spatially and temporally modulated metamaterial, whose dielectric susceptibility is similar to moving dielectrics. We show that the vacuum contribution to the photodetection signal is non-zero due to the negative frequencies even in the far-field zone. Hence, certain dielectric features can be determined without radiating any incident field on the dielectric. When the incident light is scattered (or re-radiated), the determination of dielectric susceptibility is enhanced and overcomes Rayleigh's limit in the far-field zone. We study similar effects for an inhomogeneous dielectric moving with a constant speed, a problem we consider within relativistic optics. Now the vacuum contribution to the photodetection signal reflects dielectric features, can be long-range in space but is not a far-field effect.

Transient Liquid Phase bonding in the nickel base superalloy CM 247 LC

description: In this work, the effects of temperature and time were investigated on the microstructure and properties of Transient Liquid Phase bonds in the directionally solidified superalloy CM 247 LC with a commercial braze filler material MBF-80 (Ni-Cr-B-C). Specimens were bonded at 1070°C, 1125°C and 1170°C for durations of 15 minutes, 1 hour and 4 hours. The resultant microstructures were then examined metallographically using optical and scanning electron microscopes. The mechanical properties were determined by micro-hardness and tensile tests. The microstructure of bonded joints contained blocky and acicular precipitates in the base material. The chemical compositions of these precipitates were found to be similar and were nickel depleted and tungsten rich compared to the base metal. Mechanical tests made it evident that completion of the isothermal solidification in a TLP bond joint does not guarantee satisfactory joint properties. Extensive precipitation of hard and brittle phases and chemical inhomogeneity in the joint microstructure warrants further postbond heat treatment. Models of the TLP bonding process, available in the literature, were applied in this work. The apparent activation energy for the diffusion of boron in CM 247 LC was found to be 219 kJ/mol. Analytical models predicted isothermal solidification times in close agreement with experimental observations. Two numerical models were developed in this work included a moving boundary model based on diffusion coefficients and equilibrium compositions and a phenomenological model coupled to thermodynamic and atomic mobility databases. The moving boundary model predicted satisfactory isothermal solidification times. The phenomenological model predicted times which were generally lower than those found experimentally. From this work, it is apparent that the mobility data available for boron is insufficient for the current system.

description: The aim of this paper is to point out some problems of index estimation for the purposes of weather derivative valuation considering the particularities of agriculture. The assessment of the sensitivity of barley to weather over 40 years has been the basis for the design and valuation of weather derivative in the Czech Republic (The Southern Moravia Region). The analysis is based on regression modeling using temperature index and barley yield. The burn analysis based on parametric bootstrap is used as the method for the valuation of weather derivative contract. With the effective bootstrap tool, the burn analysis may easily be processed and the uncertainty about the pay-off, option price and statistics of probability distribution of revenues can be effectively determined. Nevertheless, the results of the analysis reveal a significant adverse impact of basis risk on the quality of agricultural weather derivative in the Czech growing conditions. The article outlines the scope for use of weather derivative as the reinsurance tool in regions with frequent occurrence of systematic weather risk.

In this study, we examine the use of an Artificial Neural Network (ANN) model to automatically extract the IPA phonemic pronunciation of a word based on its audio pronunciation, hence its name Generating IPA Pronunciation From Audio (GIPFA). Based on the French Wikimedia dictionary, we trained our model which then correctly predicted 75% of the IPA pronunciations tested. Interestingly, by studying inference errors, the model made it possible to highlight possible errors in the dataset as well as to identify the closest phonemes in French.

description: NASYP is an online Geoportal tool being developed in cooperation with state and regional authorities to improve insufficient practices based on implementation of Directive nr. 2003/105/ES on the control of major-accident hazards involving dangerous substances. The tool is applicable for managing the permits, reporting and regular monitoring issues. Furthermore, it’s applicable for a risk assessment and a rapid management of disasters in the initial phase. There’re simple modeling tools included to simulate early stages of the contamination caused by disasters occurred to be used for decision making and effective use of emergency services. In this manner, there’re low atmospheric and surface water pollutions taken into account. For the study area, Liberec region was chosen covering the area of 3,163km2 and containing 533 potentially dangerous objects categorized accordingly to the Directive nr. 2003/105/ES. The model simulations are responding to daily hydrological and meteorological situation, a capability of automated updates from databases operated by the Czech Hydro Meteorological Institute, and communicate with databases of substances operated by the regional authorities. NASYP is suitable especially for the “N” class of the operators defined in the Directive, where because of smaller amounts of stored dangerous substances the safety measures and regular inspections are limited.

To get a new insight into this issue, we propose the concept of the border of spacetime as a generalization of the spacetime singularity and discuss its visibility. The visible border, corresponding to the naked singularity, is not only relevant to mathematical completeness of general relativity but also a window into new physics in strongly curved spacetimes, which is in principle observable.

Identifying new inhibitors of bacterial RNA polymerase: screening a synthetic chemical library and microbial extracts
Creators: name: Wu, Pengpeng
Publisher: name: No Publisher Supplied
Year: 2021

description: Rifampicin (Rif) is widely used in the treatment of Gram-positive and Gram-negative bacterial infections and is currently a first-line clinical anti-tuberculosis drug. Rif functions by binding to and inhibiting bacterial RNA polymerase (RNAP). The clinical utility of existing antibiotics, including Rif, is increasingly threatened by the emergence, and spread of drug-resistant bacterial strains. Tuberculosis resistance to Rif, in particular, poses a huge threat to the health of all mankind. There is an urgent need for new antibacterial compounds that can replace Rif. (Ho et al.,2009) (AM et al., 1959) In this work, I screened a synthetic chemical library of 98 nucleoside analogs from Janssen Pharmaceuticals for their ability to inhibit Escherichia coli RNAP, Mycobacterium tuberculosis RNAP, and bacteriophage SP6 RNAP. I identified 9 compounds that showed inhibition of one or more of the above RNAPs. Of these, 6 compounds were selective for bacterial RNAP over human RNAPs I/II/III. I also confirmed the hypothesis that the mechanism of inhibition of Janssen compounds involves competition with NTP to occupy the RNAP nucleotide addition site. In addition, I inferred the base specificity of the 9 compounds competing and the possible base identity of the analogs. In addition, I tested 984 microbial extracts with my colleague for their ability to inhibit Rif-resistant E. coli RNAP (E. coli S531L RNAP), Rif-resistant M. tuberculosis RNAP (Mtb S'531'L RNAP), and bacteriophage SP6 RNAP. I found there are 54 extract fractions which can inhibit either E. coli S531L RNAP and Mtb S'531'L RNAP. I further tested whether they could inhibit the structurally unrelated bacteriophage SP6 RNAP. I found that 32 of the extract fractions also inhibit SP6 RNAP as well as or better than they inhibit E. coli S531L RNAP and Mtb S'531'L RNAP, also found that 12 extracts strongly inhibited Rif-resistant E. coli RNAP, but not bacteriophage SP6 RNAP, indicating selectivity for bacterial RNAP. Another 10 extracts showed more moderate, selective inhibition of E. coli S531L RNAP or Mtb S'531'L RNAP.
Mathematical study of Rho GTPases in motile cells

description: Rho family GTPases play an essential role in cell motility, transducing extracellular signal to the actin cytoskeleton. This thesis presents the formulation and analysis of several models concerning three.members of the Rho family: Cdc42, Rac, and Rho. Experimental observations of the spatio-temporal dynamics of these proteins give evidence of spatial polarization and mutual exclusion between Cdc42/Rac and Rho, which suggests that the Rho protein system is bistable. Biochemical evidence shows that there is crosstalk between the Rho proteins. However, current biological literature includes multiple (and often contradictory) hypotheses about these mutual interactions. We idealize the indirect pathways between the Rho proteins as direct effects (positive or negative feedback from one protein to another), and investigate the various proposed interactions to determine which of them can give rise to a bistable " toggle switch", alternating between a high level of Cdc42/Rac, low level of Rho steady state and low level of Cdc42/Rac, high level of Rho steady state. We discuss the biological interpretation of our findings. Next, we investigate a spatial variant of a model with suitable interactions to determine if it can give rise to spatial segregation of Rho proteins. We find that in a suitable parameter regime, a small initial gradient of one of the proteins will become amplified and give rise to long-lasting spatial segregation of Cdc42/Rac and Rho. On a longer timescale, the system eventually reaches a spatially uniform high Cdc42/Rac and low Rho steady state. Finally, a multi-compartment model for the activation of a single Rho family GTPase that includes a greater level of biological detail is developed. Parameter values for this model are obtained from biochemical literature. This compartment model can be used as a subunit in more realistic models of cell polarization and motility when further details of the biochemistry and interactions of the Rho proteins emerge from experimental data.

description: Atomic forces are calculated for first-row monohydrides and carbon monoxide within electronic quantum Monte Carlo (QMC). Accurate and efficient forces are achieved by using an improved method for moving variational parameters in variational QMC. Newton's method with singular value decomposition (SVD) is combined with steepest descent (SD) updates along directions rejected by the SVD, after initial SD steps. Dissociation energies in variational and diffusion QMC agree well with experiment. The atomic forces agree quantitatively with potential energy surfaces, demonstrating the accuracy of this force procedure. The harmonic vibrational frequencies and anharmonicity constants, derived from the QMC energies and atomic forces, also agree well with experimental values.

11D Supergravity as a gauge theory for the M-algebra

description: The eleven-dimensional gravitational action invariant under local Poincare transformations is given by the dimensional continuation of the Euler class of ten dimensions. Here we show that the supersymmetric extension of this action leads, through the Noether procedure, to a theory with the local symmetry group given by the M-algebra. The fields of the theory are the vielbein, the Lorentz (spin) connection, one gravitino, and two 1-forms which transform as second and fifth rank antisymmetric Lorentz tensors. These fields are components of a single connection for the M-algebra and the supersymmetric Lagrangian can be seen to be a Chern-Simons form. The dynamics has a multiplicity of degenerate vacua without propagating degrees of freedom. The theory is shown to admit solutions of the form S^{10-d} x X_{d+1}, where X_{d+1} is a warped product of R with a d-dimensional spacetime. Among this class, the gravitational effective action describes a propagating graviton only if d=4 and the spacetime has positive cosmological constant. The perturbations around this solution reproduce linearized General Relativity around four-dimensional de Sitter spacetime.

Cardy-Verlinde Formula and Holographic Dark Energy

description: If we separate energy in a holographic theory into an extensive part and an intrinsic part, where the extensive part is given by the cosmological constant, and assume entropy be given by the Gibbon-Hawking formula, the Cardy-Verlinde formula then implies an intrinsic part which agrees with a term recently proposed by Hsu and Zee. Moreover, the cosmological constant so derived is in the form of the holographic dark energy, and the coefficient is just the one proposed recently by Li. If we replace the entropy by the so-called Hubble bound, we show that the Cardy-Verlinde formula is the same as the Friedmann equation in which the intrinsic energy is always dark energy. We work in an arbitrary dimension.

description: The present paper introduces chosen results of an ICT development survey in the regions of the Czech Republic. The survey was primarily focused on broadband connectivity and its adoption by agricultural enterprises operating in rural areas. The survey was conducted in the context of both the EU strategy "Digital Agenda for Europe" and the national program document "National Policy in Electronic Communications - Digital Czech Republic". It stems from the enquiries that the situation is not – in spite of a certain improvement – satisfactory and the digital divide remains highly topical in rural areas of the Czech Republic. Broadband connectivity reaches practically 100% in urban areas and more than 85% in suburban areas whereas the rural areas show only about 75% availability. In many parts of the Czech Republic, a high quality Internet connection is quite questionable and sometimes even unavailable until present.

description: We present a turbulence-sustaining mechanism in a spinor Bose-Einstein condensate, which is based on the chaotic nature of internal spin dynamics. Magnetic driving induces a complete chaotic evolution of the local spin state, thereby continuously randomizing the spin texture of the condensate to maintain the turbulent state. We experimentally demonstrate the onset of turbulence in the driven condensate as the driving frequency changes and show that it is consistent with the regular-to-chaotic transition of the local spin dynamics. This chaos-assisted turbulence establishes the spin-driven spinor condensate as an intriguing platform for exploring quantum chaos and related superfluid turbulence phenomena.

DETERMINANTS OF THE DEMAND FOR ORGANIC AND CONVENTIONAL FRESH MILK IN GERMANY– AN ECONOMETRIC ANALYSIS

description: An increasing number of studies deals with consumer decisions regarding organic food, but only a few provide quantitative estimates of price and income elasticities. This paper contributes to the existing literature by providing own-price elasticity estimates as well as an analysis of the sociodemographic determinants of demand for organic milk. The analysis is based on the GfK Consumer Scan Scanner panel dataset on food purchases of German households covering a sample period of four years from 2004 to 2007. A two-step estimation procedure is applied. First, a probit regression examines which household characteristics affect the probability to buy organic milk. Second, a fixed-effects panel regression determines factors that have an impact on the quantity demanded. Finally, the study investigates whether the price elasticity of demand depends on income, age or household size and whether the price elasticity varies among different retail formats. The results show that the probability to buy organic milk increases with education and income level. Furthermore, the demand is on average higher in households with young children and with a female being mainly responsible for food purchases. However, the probability declines when there is more than one child per household. The results of the fixed-effects regression indicate that the demand for organic milk in Germany is highly price-inelastic. Low absolute price elasticities for organic milk indicate that price promotions at retail level will not lead to an increase in sales. As expected, for all types of milk price sensitivity is higher, but still inelastic, in discount shops than in other retail formats such as supermarkets or large-scale retail. Demand in organic food shops is the least responsive to price changes. Besides, households headed by a person younger than 25 or older than 45 years show a higher price responsiveness than middle-aged households.
