The Redundancy Matrix as a Performance Indicator for Structural Assessment
Creators: name: Forster, David
name: von Scheven, Malte
Publisher: name: arXiv
Year: 2024
Subjects: subject: Computational Engineering, Finance, and Science (cs.CE)
subject: FOS: Computer and information sciences

description: The degree of static indeterminacy and its spatial distribution characterize load-bearing structures independent of a specific load case. The redundancy matrix stores the distribution of the static indeterminacy on its main diagonal, and thereby offers the possibility to use this property for the assessment of structures. It is especially suitable to be used in early planning stages for design exploration. In this paper, performance indicators with respect to robustness and assemblability are derived from the redundancy matrix. For each of the performance indicators, a detailed matrix-based derivation is given and the application is showcased with various truss examples.

description: This paper contributes to the foregoing discussion on networks in agribusiness. It is grounded in business network approach. The aim of the paper is to recognise and evaluate distinguishing features of agribusiness networks. The eighteen Polish fruit and vegetable producers, processors and traders were investigated. Their network activities have been recognised as non-transactional exchange of knowledge and information, mutual adaptations, adjustments and standardizations. They are preceded by strong transactional relationships in the supply chain which are based on pricing conditions and terms of payments, cooperation as well as formal contracts. The network activities are reinforced by common aims, reciprocal trust and commitment, mutual benefits and stability. The main aim of networking is to increase profits and it is correlated with optimization of supplies and provisions, building of community and relationships and sustainable development. The study classifies five categories of agribusiness networks in the queried sample. They are: very strong operational, strong sustainable, moderate social, weak innovative and very weak shared resource. The paper concludes that the studied networks are characterized by strong actor and activity ties and weak resource bonds. Principally, non-appearance of shared resources may influence the weak innovative ability of networks in the fruit and vegetable industry.

description: Sustainability of increasing relevance also for seafood markets. The aim of this contribution is to analyse consumer preferences and their willingness to pay (WTP) for different sustainability claims. The contingent valuation method was applied to elicit consumers’ WTP in eight European countries. The WTP varies between seven and almost 20%, depending on attribute and country. Three consumer groups become apparent: the largest group without any additional WTP, a smaller group with a moderate additional WTP of plus 17%, and a very small group with an additional WTP of more than 40%. Clear differences between countries regarding preferences for different sustainability attributes, particularly in the segment with highest WTP are obvious.
Close stars and accretion in Low Luminosity Active Galactic Nuclei
Creators: name: Nayakshin, Sergei
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Quasar accretion disks are believed to form stars by self-gravity. Low Luminosity Active Galactic Nuclei (LLAGN) are much dimmer galactic centers, and are often believed to be quasars that ran out of gaseous fuel. LLAGN accretion disks should thus co-exist with thousands to millions of stars or proto-stars left from the previous stronger accretion activity. In principle, these stars may produce several important effects: (i) contribute to the optical/UV spectra of some LLAGN; (ii) reprocessing of the stellar radiation in the dusty disks could dominate the LLAGN infra-red spectra; (iii) deplete the (accretion) gas disk much faster than it can accrete onto the supper-massive black hole (SMBH); (iv) stars, individually or in groups, may slow down and modulate the accretion flow significantly due to their inertia. In this way they may produce the LLAGN cut-off disks; (v) alternatively, frequent enough stellar collisions and resulting stellar disruptions could keep the inner disk empty. Here we explore these ideas. We find that, despite ``low'' luminosities of LLAGN, unrealistically high stellar densities are required to make a sizable radiative contribution to the (HST) optical/UV spectra of these galactic nuclei. Stellar contribution to the infrared spectrum is more likely. Further, if LLAGN are in a quasi steady-state for as long as 10^7 years or more, too high stellar densities would again be required to significantly affect the dynamics of accretion flow. However, if LLAGN are ``short''-lived phenomena, e.g. t < 10^5 years, quiescent states of quiescence-outburst cycles, then embedded stars may be much more important through the mass effects (iii) -- (v). With observations of LLAGN becoming progressively better, it will be more and more difficult to neglect the presence of close stars in and around nuclear accretion disks.

description: Objective: This study aimed to analyze the cognitive psychological process and to understand the decision-making process involved in university student passengers’ seat belt usage behavior and the difference between front and rear seat belt use. Based on the Theory of Planned Behavior (TPB), two extended variables, namely, perceived accident severity and safety consciousness, were introduced. From the perspective of social psychology, we explored the psychological factors influencing university student passengers’ seat belt usage behavior and the relationship between these factors. Methods: The reliability and validity of 544 valid questionnaires were tested, and the differences were analyzed in the scores of the TPB variables between university student transportation majors and other majors. Finally, structural equation models were established to compare the factors affecting seat belt usage in the front and rear seats. Results: The results show that the TPB could effectively explain and predict university student passengers’ seat belt usage behavior. Significant differences were observed in the TPB variables, the extended variables and the behavioral intention scores between the university students majoring in transportation and those with other majors. In addition, significant differences were observed between front and rear seat belt usage. All psychological factors had significant positive effects on the seat belt usage behavior of the university student passengers, and all factors directly or indirectly affected seat belt usage behavior. Conclusions: The present research adds further empirical evidence regarding the ability of the TPB to predict seat belt usage behavior. In addition, the current research results may provide a theoretical basis for policy-making aiming to improve university students’ seat belt usage.

description: The Life Cycle Assessment (LCA) approach is the most important tool in the evaluation of environmental (sustainability) impacts of products and processes. We used the method to conduct an impact analysis with regard to raw material inputs (pulp) for the German paper production industry. In our analysis, we compare the environmental effects of primary sulphate pulp, scrap paper pulp and grass-based pulp and estimate their impacts in the impact categories “greenhouse gas emissions”, “eutrophication” as well as “energy and water consumption”. Furthermore, we discuss the opportunities of the methodical approach and some general problems and limits of the application of a LCA. In conclusion, we found environmental advantages for the use of grass as an alternative resource in the German paper production industry, especially in the fields of transport and water consumption.

Year: 2020
Subjects: subject: High Energy Physics - Theory (hep-th)

description: A classical result from analytic number theory by Rademacher gives an exact formula for the Fourier coefficients of modular forms of non-positive weight. We apply similar techniques to study the spectrum of two-dimensional unitary conformal field theories, with no extended chiral algebra and $c>1$. By exploiting the full modular constraints of the partition function we propose an expression for the spectral density in terms of the light spectrum of the theory. The expression is given in terms of a Rademacher expansion, which converges for spin $j \neq 0$. For a finite number of light operators the expression agrees with a variant of the Poincare construction developed by Maloney, Witten and Keller. With this framework we study the presence of negative density of states in the partition function dual to pure gravity, and propose a scenario to cure this negativity.

description: A GI system for protection of agricultural products and foodstuffs has been recently introduced in Japan aiming to provide a tool for: i) tapping into rural development; ii) increasing exports; iii) preserving the traditional products’ heritage and iv) improve products’ differentiation. Twelve registered GIs are analysed by grouping them in four categories according to their target market and consumer awareness. Our direct survey findings show that each product category is mainly focused on one of the above-mentioned targets, has specific SWOT factors, has different expectations from the GI recognition, its GIs’ governance system works differently, and that specific well-tailored policies are needed.

description: The nucleon-nucleon interaction is constructed by means of the $J$-matrix version of inverse scattering theory. Ambiguities of the interaction are eliminated by postulating tridiagonal and quasi-tridiagonal forms of the potential matrix in the oscillator basis in uncoupled and coupled waves, respectively. The obtained interaction is very accurate in reproducing the $NN$ scattering data and deuteron properties. The interaction is used in the no-core shell model calculations of $^3$H and $^4$He nuclei. The resulting binding energies of $^3$H and $^4$He are very close to experimental values.

description: Currently, there are intense experimental efforts to realize lattice gauge theories in quantum simulators. Except for specific models, however, practical quantum simulators can never be fine-tuned to perfect local gauge invariance. There is thus a strong need for a rigorous understanding of gauge-invariance violation and how to reliably protect against it. As we show through analytic and numerical evidence, in the presence of a gauge invariance-breaking term the gauge violation accumulates only perturbatively at short times before proliferating only at very long times. This proliferation can be suppressed up to infinite times by energetically penalizing processes that drive the dynamics away from the initial gauge-invariant sector. Our results provide a theoretical basis that highlights a surprising robustness of gauge-theory quantum simulators.

description: O actual contexto educativo, a nível do ensino superior, está marcado pela implementação do Processo de Bolonha. As mudanças que estão a ocorrer devem ser encaradas como uma oportunidade não só para reestruturar a actual oferta formativa pelas instituições universitárias, mas também para oferecer novas formações que estejam em sintonia com a evolução da sociedade e do mercado. Entre outros campos do saber que primam pela inovação, as Ciências da Informação e da Documentação têm nos últimos anos constituído uma área que vê multiplicar-se a oferta de formações a nível internacional. Urge, portanto, a nível nacional complementar a oferta formativa neste domínio, oferecendo cursos que se norteiem pelos parâmetros “bolonheses” da empregabilidade, mobilidade e formação ao longo da vida. Com este artigo pretendemos dar um contributo para que a nível nacional seja ministrada uma formação adequada aos profissionais da informação e da documentação. A nossa análise centra-se, essencialmente, numa retrospectiva sobre a oferta de formação a nível europeu e nacional, para depois descrevermos as linhas gerais da oferta formativa que a Universidade de Évora pretende implementar.

description: Adversarial machine learning is an emerging field that focuses on studying vulnerabilities of machine learning approaches in adversarial settings and developing techniques accordingly to make learning robust to adversarial manipulations. It plays a vital role in various machine learning applications and has attracted tremendous attention across different communities recently. In this paper, we explore different adversarial scenarios in the context of quantum machine learning. We find that, similar to traditional classifiers based on classical neural networks, quantum learning systems are likewise vulnerable to crafted adversarial examples, independent of whether the input data is classical or quantum. In particular, we find that a quantum classifier that achieves nearly the state-of-the-art accuracy can be conclusively deceived by adversarial examples obtained via adding imperceptible perturbations to the original legitimate samples. This is explicitly demonstrated with quantum adversarial learning in different scenarios, including classifying real-life images (e.g., handwritten digit images in the dataset MNIST), learning phases of matter (such as, ferromagnetic/paramagnetic orders and symmetry protected topological phases), and classifying quantum data. Furthermore, we show that based on the information of the adversarial examples at hand, practical defense strategies can be designed to fight against a number of different attacks. Our results uncover the notable vulnerability of quantum machine learning systems to adversarial perturbations, which not only reveals a novel perspective in bridging machine learning and quantum physics in theory but also provides valuable guidance for practical applications of quantum classifiers based on both near-term and future quantum technologies.

description: Representing 30% of food intake of 60% of planet’s inhabitants, rice is a staple food all over the world. According to FAO, worldwide rice production is about 504 million tons (milled basis) in 2017, while international rice trade is 45 million tons. With almost 9% exported, rice is not the top trade food commodity. 43% of wine worldwide produced is exported, 23% of wheat, 11% of maize and 7% of meat. The rice market is mainly composed of coarse rice all over the world. It also includes 18% of aromatic rice, coming from a limited number of countries where the pedoclimatic conditions and human know-how make a specific terroir. Aromatic rice is often protected by a Geographical Indication (GI). This is the case of Basmati, from India and Pakistan, using a collective trade mark since 2008 in Pakistan, and Jasmine from Thailand, bearing a Protected Geographical Indication (PGI) as Khao Hom Mali, since 2013.
Cluster Heating by Viscous Dissipation of Sound Waves

description: We simulate the effects of viscous dissipation of waves that are generated by AGN activity in clusters of galaxies. We demonstrate that the amount of viscous heating associated with the dissipation of these waves can offset radiative cooling rates in cooling flow clusters of galaxies. This heating mechanism leads to spatially distributed and approximately symmetrical dissipation. The heating waves reach a given distance from the cluster center on a timescale shorter than the cooling time. This means that this heating mechanism has the potential of quenching cooling flows in a quasi-stable fashion. Moreover, the heating is gentle as no strong shocks are present in the simulations. We first investigated whether a single continuous episode of AGN activity can lead to adequate dissipation to balance cooling rates. These simulations demonstrated that, whereas secondary waves generated by the interaction of the rising bubble with the intracluster medium are clearly present, viscous heating associated with the dissipation of these waves is insufficient to balance radiative cooling. It is only when the central source is intermittent that the viscous dissipation of waves associated with subsequent episodes of activity can offset cooling. This suggests that the ripples observed in the Perseus cluster can be interpreted as being due to the AGN duty cycle, i.e., they trace AGN activity history. The simulations were performed using the PPM adaptive mesh refinement code FLASH in two dimensions.

title: Two methods of modelling electric current systems by analysis of magnetic field data, with particular reference to the quasi-dc magnetic field of the human leg
Creators: name: Grimes, David
Publisher: name: The Open University
Year: 1989

description: This thesis deals with two approaches to the problem of obtaining information about electric current distributions by analysing the associated magnetic field. Both methods have been developed within the context of a particular biomagnetic study, the analysis of the quasi dc magnetic field of the human leg. The techniques have been designed to deal with data sensed by a gradiometer in a series of horizontal scans above the current—carrying region and take full account of the gradiometer configuration. Method 1, the line-dipole technique, analyses each scan individually and calculates the dipole term of a multipole expansion which best characterises the current distribution cross-section immediately below the line of scan. Method 2, the line current loop iterative-perturbative algorithm, uses data from all the scans to compute the coordinates of the best fit line current loop for the whole data map. Both methods have been extensively tested with computer simulated data and with real data from current-carrying wire loops and the results show that both methods are capable of producing an accurate replication of the target system provided it satisfies the initial model assumptions. The dc magnetic field of the human leg has been investigated for a number of normal subjects. The line- dipole technique provides a useful method of characterising the data and indicates regions of high current density which allow inferences to be drawn about the physiological nature of the current generators. Analysis of the field from a leg with a fibula fracture shows significant differences from the normal pattern, although a direct, causal connection with the fracture is not necessarily implied. The line current loop technique has been less successful in achieving a high quality fit to the leg data but this lack of success is consistent with a physiologically reasonable model of the source currents. Although both methods have been designed for this rather specialised biomagnetic inverse problem, they are of more general applicability and may be useful in other fields such as geophysics or non-destructive testing.

description: A general scheme of construction and analysis of physical fields on the various homogeneous spaces of the Poincaré group is presented. Different parametrizations of the field functions and harmonic analysis on the homogeneous spaces are studied. It is shown that a direct product of Minkowski spacetime and two-dimensional complex sphere is the most suitable homogeneous space for the subsequent physical applications. The Lagrangian formalism and field equations on the Poincaré group are considered. A boundary value problem for the relativistically invariant system is defined. General solutions of this problem are expressed via an expansion in hyperspherical harmonics on the complex two-sphere. A physical sense of the boundary conditions is discussed. The boundary value problems of the same type are studied for the Dirac and Maxwell fields. In turn, general solutions of these problems are expressed via convergent Fourier type series. Field operators, quantizations, causal commutators and vacuum expectation values of time ordered products of the field operators are defined for the Dirac and Maxwell fields, respectively. Interacting fields and inclusion of discrete symmetries into the framework of quantum electrodynamics on the Poincaré group are discussed.

Ailuroedus crassirostris blaauwi Mathews, 1912a: 439 (Richmond River, New South Wales).
Now Ailuroedus crassirostris (Paykull, 1815). See Mathews, 1913a: 309; 1926: 314–317; Hartert, 1929a: 55; Mayr and Jennings, 1952: 2–3; Mayr, 1962c: 173–175; Gilliard, 1969: 263–266; Beehler and Finch, 1985: 55; Beehler et al., 1986: 220; Schodde and Mason, 1999: 622–624; Dickinson, 2003: 427; Frith and Frith, 2004: 249–250; Christidis and Boles, 2008: 179–180; and Frith and Frith, 2009a: 394.
HOLOTYPE: AMNH 679627, adult female, collected at Rous Mill (= Rous), 28.53S, 153.23E (USBGN, 1957), Richmond River, New South Wales, Australia, in October 1905, by P. Schrader. From the Mathews Collection (no. 3645) via the Rothschild Collection.
COMMENTS: Mathews cited his catalog number of the type in the original description. I have considered the following specimens paratypes: AMNH 679621–679626, 679628–679632, six males, five females, all collected at Rous or on the Richmond River, between August 1903 and October 1908. The following Mathews catalog numbers apply to this form, but I could not correlate all the numbers with the specimens and some numbers apparently covered more than one specimen bearing the same data: 3643, 3644, 3950, 5535, 5536, 5999, 6000, 6001. The Mathews and Rothschild type labels bear Mathews no. 3646, but Schrader’s label is correctly numbered 3645. The number 3646 in Mathews’ catalog refers to a specimen of Strepera graculina. AMNH 679621 bears a ‘‘Figured’’ label, indicating that it served as the model for Mathews (1926: pl. 730, opp. p. 314; text p. 315), where it is described but not said to be the type. By 1913, Mathews (1913a: 309) considered A. crassirostris monotypic and blaauwi a synonym.
There is still much discussion as to whether Ailuroedus melanotis should be considered a species separate from A. crassirostris. Schodde and Mason (1999: 622–624) gave a thorough discussion of the various treatments and combined the populations in a single species; this was followed by Dickinson (2003: 427).

description: This article investigates properties of semiclassical Gauge Field Theory Coherent States for general quantum gauge theories. Useful, e.g., for the canonical formulation of Lattice Gauge Theories these states are labelled by a point in the classical phase space and constructed such that the expectation values of the canonical operators are sharply peaked on said phase space point. For the case of the non-abelian gauge group SU(2), we will explicitly compute the expectation value of general polynomials including the first order quantum corrections. This allows asking more precise questions about the quantum fluctuations of any given semiclassical system.

description: Na transição do século XX para o século XXI, nota-se a tomada de consciência pela quase totalidade dos responsáveis europeus pelo Ensino Superior da necessidade de uma reforma do mesmo no sentido de o tornar verdadeiro catalisador de uma sociedade com maior mobilidade e acesso ao conhecimento. Às Ciências da Informação e Documentação cabe qualificar o acesso à nova esfera de bens culturais disponibilizados em simultâneo em todo o planeta de forma inaudita respeitando os valores da pós-modernidade: a ecologia e a felicidade humana, o bem-estar do homem concreto, a partilha responsável do saber, a transparência dos actos económicos e políticos, a denúncia da corrupção e a desmistificação. A prodigiosa capacidade de acumulação de informação técnica, científica e humanista coloca desafios mais prementes aos profissionais BAD, de certa forma intermediários entre as duas principais esferas nos âmbitos do saber e da cultura: a dos autores e a dos consumidores, a do conhecimento e a da acção. A sua formação deve, pois, assumir, em simultâneo e a todos os níveis, as características de unitária e plural, técnica e humanista e incluir tanto a Sociologia, a Cultura e a Psicologia, como o Direito, a Gestão e as técnicas de informação.

description: Objective: The objective of this paper is to identify the list of crash severity contributing factors and evaluate their impact on multiple-vehicle crashes on two high use Trans-European interurban, freight corridors in Spain (southern Europe): Madrid - Irùn and Barcelona – Almerìa. Methods: We have used both logistic regression and random forests to identify crash severity predictors and estimate their impacts on crash outcomes. Although both statistical methods can provide useful information to help explain the safety implications of highway crashes, using both methods may further enable a more comprehensive understanding of this phenomenon. For this effort, we disaggregated the crash data into different crash types (i.e., head-on, angle, sideswipe and rear-end) and analyzed this data using roadway design elements, driver characteristics, and environmental factors. To identify the most important predictors of crash severity, we used the random forests data mining approach. We then used ordered logit models to estimate the effect of external factors on the severity of each crash type. Finally, we assessed the accuracy of the model estimates using bootstrap sampling. Results: The results of data mining analyses indicated that roadway design factors such as horizontal and vertical curvature, super elevation, and lane and shoulder width are among the most important factors associated with crash severity. The results of logistic regression show that the impact of the selected roadway element on the crash outcome is conditional on the crash type and the direction of the effects is not always consistent. Conclusions: The contribution of this paper to the existing literature is two-fold: the first important contribution of the paper is related to the safety analysis of two of the most important freight corridors in Spain and southern Europe. The second contribution of this paper is to address the existing gap in the literature relating to the comparison and compatibility of data mining and the logistic regression model.

We show that there exists a unique generating superpotential for these models. The location of the black brane and the associated Hawking temperature depend on the value of the the 3-brane tension while other parameters are held fixed. The thermodynamics of these solutions are presented, from which we show that the entropy satisfies $S

description: Abstract

The three new autonomous regions (DOBs) in Pegunungan Bintang Regency, Papua, are believed to be a catalyst for social progress for the Okmin community in the outermost border area. This study aimed to analyze the potential and challenges of the Pegunungan Bintang DOBs' expansion on the social progress of the Okmin community. This study used a qualitative method with a case study approach. Data were collected through in-depth interviews with key informants, observation, and document review. The results of the study showed that the expansion of the Pegunungan Bintang DOBs has the potential to improve the social progress of the Okmin community, especially in terms of access to education, health, and infrastructure. However, the expansion of the DOBs also faces a number of challenges, such as the potential for inter-ethnic conflict, corruption, and development inequality. To overcome these challenges, the government needs to carry out the planning and implementation of the DOBs' expansion with the active involvement of the Okmin community. The government also needs to ensure that the expansion of the DOBs is not only beneficial to political elites, but also to the wider community.

The Acceleration and Storage of Radioactive Ions for a Beta-Beam Facility

description: The term beta-beam has been coined for the production of a pure beam of electron neutrinos or their antiparticles through the decay of radioactive ions circulating in a storage ring. This concept requires radioactive ions to be accelerated to as high Lorentz gamma as 150. The neutrino source itself consists of a storage ring for this energy range, with long straight sections in line with the experiment(s). Such a decay ring does not exist at CERN today, nor does a high-intensity proton source for the production of the radioactive ions. Nevertheless, the existing CERN accelerator infrastructure could be used as this would still represent an important saving for a beta-beam facility.

description: In this study, we analyze various Iterative Stockholder Analysis (ISA) methods for molecular density partitioning, focusing on the numerical performance of the recently proposed Linear approximation of Iterative Stockholder Analysis model (LISA) [J. Chem. Phys. 156, 164107 (2022)]. We first provide a systematic derivation of various iterative solvers to find the unique LISA solution. In a subsequent systematic numerical study, we evaluate their performance on 48 organic and inorganic, neutral and charged molecules and also compare LISA to two other well-known ISA variants: the Gaussian Iterative Stockholder Analysis (GISA) and Minimum Basis Iterative Stockholder analysis (MBIS). The study reveals that LISA-family methods can offer a numerically more efficient approach with better accuracy compared to the two comparative methods. Moreover, the well-known issue with the MBIS method, where atomic charges obtained for negatively charged molecules are anomalously negative, is not observed in LISA-family methods. Despite the fact that LISA occasionally exhibits elevated entropy as a consequence of the absence of more diffuse basis functions, this issue can be readily mitigated by incorporating additional or integrating supplementary basis functions within the LISA framework. This research provides the foundation for future studies on the efficiency and chemical accuracy of molecular density partitioning schemes.

description: Quasiparticle states in Dirac systems with complex impurity potentials are investigated. It is shown that an impurity site with loss leads to a nontrivial distribution of the local density of states (LDOS). While the real part of defect potential induces a well-pronounced peak in the density of states (DOS), the DOS is either weakly enhanced at small frequencies or even forms a peak at the zero frequency for a lattice in the case of non-Hermitian impurity. As for the spatial distribution of the LDOS, it is enhanced in the vicinity of impurity but shows a dip at a defect itself when the potential is sufficiently strong. The results for a two-dimensional hexagonal lattice demonstrate the characteristic trigonal-shaped profile for the LDOS. The latter acquires a double-trigonal pattern in the case of two defects placed at neighboring sites. The effects of non-Hermitian impurities could be tested both in photonic lattices and certain condensed matter setups.
