description: This study presents a grey-box recursive identification technique to estimate key parameters in a mineral flotation process across two scenarios. The method is applied to a nonlinear physics-based dynamic model validated at a laboratory scale, allowing real-time updates of two model parameters, n and C, in response to changing conditions. The proposed approach effectively adapts to process variability and allows for continuous adjustments based on operational fluctuations, resulting in a significantly improved estimation of concentrate grade - one key performance indicator. In Scenario 1, parameters n and C achieved fit metrics of 97.99 and 96.86, respectively, with concentrate grade estimations improving from 75.1 to 98.69 using recursive identification. In Scenario 2, the fit metrics for n and C were 96.27 and 95.48, respectively, with the concentrate grade estimations increasing from 96.27 to 99.45 with recursive identification. The results demonstrate the effectiveness of the proposed grey-box recursive identification method in accurately estimating parameters and predicting concentrate grade in a mineral flotation process.

description: This paper addresses the timing of historical transition from rural to urban activity. In our model, rural production has constant returns and meets subsistence needs, while urban production has scale economies and meets the demands of higher-income consumers. Urbanization occurs sooner when rural or urban productivity is higher or transport costs are lower. We test the model on worldwide data that divides the earth's surface at half-degree intervals into over 60,000 cells. From an independent estimate of each cell's rural and urban population history, we identify the date at which each cell achieves various thresholds of urbanization. Controlling for country fixed effects and neighbors' urbanization using spatial techniques, we find that the date at which each cell passes each urbanization threshold is positively associated with its suitability for cultivation, having seasonal frosts, more access to navigable waterways and lower elevation. Aggregating cells into countries, an earlier urbanization date is linked to higher per capita income today.
Cognitive Aesthetics, Neurosciences and Filmed Opera

description: The introductory pages of this contribution deal with one of the main discussions in the field of media studies with a possible impact on an aesthetic interpretation of filmed opera: the opposition between spectacle and narration as described by Andrew Darley. In opposition to Darley’s theory, or its possible application to filmed opera, I posit the hypothesis that the increased visibility of the actions and gestures in filmed opera enhances the audience’s attention to the narrative as one of the salient features of its aesthetic experience. The main section of this article will examine some findings in the fields of cognitive aesthetics and neurosciences as a support for a deeper understanding of the hypothesis proposed above.

The splashback radius of halos from particle dynamics: III. Halo catalogs, merger trees, and host-subhalo relations
Creators: name: Diemer, Benedikt
Publisher: name: arXiv
Year: 2020
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: Virtually any investigation involving dark matter halos relies on a definition of their radius, mass, and of whether they are a subhalo. The halo boundary is most commonly defined to include a spherical overdensity contrast (such as R200c, Rvir, and R200m), but different thresholds lead to significant differences in radius and mass. The splashback radius has recently been suggested as a more physically motivated (and generally larger) halo boundary, adding to the range of definitions. It is often difficult to assess the impact of a particular choice because most halo catalogs contain only one or a few definitions and generally only one set of host-subhalo relations. To alleviate this issue, we present halo catalogs and merger trees for 14 N-body simulations of LambdaCDM and self-similar universes. Based on ROCKSTAR catalogs, we compute additional halo properties using the SPARTA code and recombine them with the original catalogs. The new catalogs contain numerous variants of spherical overdensity and splashback radii and masses and, most critically, host-subhalo relations for each definition. We also present a new merger tree format where the data is stored as a compressed, two-dimensional matrix. We perform basic tests of the relation between different definitions and present an updated model for the splashback-spherical overdensity connection. The SPARTA code, as well as our catalogs and merger trees, are publicly available.

description: The renormalization of the attractive 1/r^2 potential has recently been studied using a variety of regulators. In particular, it was shown that renormalization with a square well in position space allows multiple solutions for the depth of the square well, including, but not requiring a renormalization group limit cycle. Here, we consider the renormalization of the 1/r^2 potential in momentum space. We regulate the problem with a momentum cutoff and absorb the cutoff dependence using a momentum-independent counterterm potential. The strength of this counterterm is uniquely determined and runs on a limit cycle. We also calculate the bound state spectrum and scattering observables, emphasizing the manifestation of the limit cycle in these observables.

description: The recently developed Negative Stiffness Honeycomb (NSH) structures have drawn tremendous interest in the field of energy absorption and shock isolation. The smart NSH structures have the advantage of being reused multiple times, where the conventional energy absorption techniques involve permanent deformation of the material via linear or nonlinear buckling or failure mode to absorb energy. In this study, the force-displacement characteristics of NSH structure with different materials has been investigated using Finite Element Method Based Software. A comprehensive investigation was undertaken to analyze the performance of the structure as energy absorbers in displacement-controlled loading conditions. From the obtained results it was observed that the NSH structure shows good energy absorption without crushing. The energy absorption characteristics were analyzed for different flexible materials commonly used in additive manufacturing. Since the structure is recoverable after each unloading, with required specific energy absorption, these structures can be used for shock isolation in sensitive structures such as small containers, packaging, small shock absorbers etc.

Ordinary Expression and Musical Expressiveness
Creators: name: Alcaraz León, María José
Publisher: name: Aisthesis. Pratiche, linguaggi e saperi dell’estetico
Year: 2014

description: A general assumption embedded in different approaches to musical expressiveness has been to accept that ordinary expression is the paradigm or the reference phenomenon for explaining other forms of (artistic) expression and in particular musical expressiveness. This has led to an attempt to find a relationship between ordinary expression and musical expressiveness that can account for why we find expressive features or content in things such as symphonies, sonatas and other forms of musical composition. In this paper I argue for the idea that musical expressiveness does not necessarily have to be understood in terms of, or by drawing an analogy to, ordinary expression. Rather, I will try, first, to defend the idea that musical expressiveness could be conceived on a continuum with ordinary expression. Secondly, I will try to show that this understanding of musical expressiveness can make more sense of the way in which some features of musical expressiveness may pass on ordinary expressiveness and enrich its repertoire.

description: The focus of the microeconomic technology adoption literature has been on the adoption and diffusion of new innovations: who adopts, and when they adopt. Implicit in the literature is that consumers will embrace the product that results from the use of the new technology. If producers have reason to believe that adopting a new technology may lead consumers to perceive differentiated products, then the decision of whether or not to adopt needs to consider not only the effectiveness of the new technology but also the consumer response to it. That is, producers have to incorporate the impact of consumer-driven market-level effects into their technology choice decisions. In these situations, producers considering the adoption of a new agricultural biotechnology have a more complex learning problem than the technology adoption literature generally addresses, because producers need to consider the interaction of demand and supply effects from the adoption of any new technology. We motivate our analysis with the case of recombinant bovine somatotropin (rbST). In order to address some of these issues, we construct an analytical model of technology adoption that considers a market with differentiated goods. We develop a multi-period economic model of a representative farmer’s technology choice decision and integrate it into a market-level analysis that links the industry’s use of the technology to the structure of consumer demand.

description: This work explores speech as a biomarker and investigates the detection of respiratory insufficiency (RI) by analyzing speech samples. Previous work \cite{spira2021} constructed a dataset of respiratory insufficiency COVID-19 patient utterances and analyzed it by means of a convolutional neural network achieving an accuracy of $87.04\%$, validating the hypothesis that one can detect RI through speech. Here, we study how Transformer neural network architectures can improve the performance on RI detection. This approach enables construction of an acoustic model. By choosing the correct pretraining technique, we generate a self-supervised acoustic model, leading to improved performance ($96.53\%$) of Transformers for RI detection.

description: Protons gain energy in short range collisions with heavier dark matter particles (DMPs) of comparable velocity dispersion. We examine the conditions under which the heating of baryons by scattering off DMPs can offset radiative cooling in the cores of galaxy clusters. Collisions with a constant cross section independent of the relative velocity of the colliding particles, cannot produce stable thermal balance. In this case, avoiding an unrealistic increase of the central temperatures yields the upper bound on the cross-section, σ_xp<10^-25 cm^2 (m_x/m_p), where m_x and m_p are the DMP and proton mass, respectively. A stable balance, however, can be achieved for a power law dependence on the relative velocity, V, of the form σ_xp \propto V^a with a

description: Schönberg’s Harmonielehre finishes on the evocation of the melody of timbre (Klangfarbenmelodie). The aim of this article is to analyse the function of timbre in relation to musical theory by establishing a parallel between the positions expressed by Schönberg and preceding classical positions, namely Jean-Jaques Rousseau’s definition of timbre and Leibniz’s concept of “clear and confused” ideas. Operating in this context, what will be shown is that timbre, according to Leibniz’s description, is a distinguishing, yet undistinguished, quality and that, precisely for this reason, timbre has a limited function in composition.

Do Null-Type Mutation Operators Help Prevent Null-Type Faults?

description: The null-type is a major source of faults in Java programs, and its overuse has a severe impact on software maintenance. Unfortunately traditional mutation testing operators do not cover null-type faults by default, hence cannot be used as a preventive measure. We address this problem by designing four new mutation operators which model null-type faults explicitly. We show how these mutation operators are capable of revealing the missing tests, and we demonstrate that these mutation operators are useful in practice. For the latter, we analyze the test suites of 15 open-source projects to describe the trade-offs related to the adoption of these operators to strengthen the test suite.

description: Network function (NF) offloading on SmartNICs has been widely used in modern data centers, offering benefits in host resource saving and programmability. Co-running NFs on the same SmartNICs can cause performance interference due to contention of onboard resources. To meet performance SLAs while ensuring efficient resource management, operators need mechanisms to predict NF performance under such contention. However, existing solutions lack SmartNIC-specific knowledge and exhibit limited traffic awareness, leading to poor accuracy for on-NIC NFs.
 This paper proposes Yala, a novel performance predictive system for on-NIC NFs. Yala builds upon the key observation that co-located NFs contend for multiple resources, including onboard accelerators and the memory subsystem. It also facilitates traffic awareness according to the behaviors of individual resources to maintain accuracy as the external traffic attributes vary. Evaluation using BlueField-2 SmartNICs shows that Yala improves the prediction accuracy by 78.8% and reduces SLA violations by 92.2% compared to state-of-the-art approaches, and enables new practical usecases.

description: This paper evaluates the long-term impact of microfinance credit from the intensity of participation in borrowing. We use a four-round panel data set on 351 farm households that had access to microfinance in northern Ethiopia. Over the years 1997-2006, with three-year intervals, households are observed on key poverty indicators: improvements in annual consumption and housing improvements. The relatively long duration in the panel enables to measure household poverty changes between consecutive periods and see the long-run effects of exposure to microfinance from the intensity of participation borrowing. The fixed-effects model is innovatively modeled to account for potential selection biases due to both time-invariant and time-varying unobserved individual household heterogeneities. Results show that microfinance borrowing indeed causally increased consumption and housing improvements. A more flexible specification that allows for the number of times the household has been in borrowing also shows that repeated borrowing is effectively increasing consumption: the longer the borrowing relationship the larger the effect partly due to lasting credit effects. Impact estimates that do not account for such dynamic effects may therefore undermine the effect of MFI borrowing.

description: The structure of the dairy processing industry in the European Union has changed enormously in recent decades. In many countries the industry is characterized by a few large companies with a big market share accompanied by many small processors that often produce for niche markets. This paper investigates which factors relate to growth of dairy processing firms. Using a unique ten-year panel data set and recently developed dynamic panel data estimators, the growth process of dairy processors is investigated for six rather diverse European countries. The data structure and the estimation method allow for dealing with endogeneity issues in an appropriate way. Firm size growth measured in total assets is found to be affected by firm size, firm age and financial variables. Growth in number of employees is only affected by firm age and lagged labour productivity. Implications for these results are given in the final section of the paper.

description: Si on considère le temps long des époques médiévale et moderne, du VIe au XVIIIe siècle, la période semble caractérisée par la « pluralité des instances normatives, des lieux de production des normes, des droits et des juridictions », comme l’écrit Elsa Marmursztejn dans La fabrique de la norme : Lieux et modes de production des normes au Moyen Âge et à l’époque moderne. Les normes se construisent, s’élaborent dans des laboratoires divers – de l’université de Paris à la cour de Versailles, des lois barbares aux officialités, de la casuistique au procès – dans la construction discursive la plus savante comme dans le « bricolage » entre acteurs divers. Cette multiplicité des normes et des espaces où celles-ci se disent et se construisent interroge. Parce qu’il permet de mettre en évidence les passages d’un discours à un autre, le dossier présenté ici atteste que les conflits de normes, loin d’être de vaines et stériles querelles, sont à leur tour un lieu efficient de construction normative.

description: Consumers have increasing demands for product standards. This has important implications for development. This paper develops a formal theory of the process of the introduction of high product standards in developing countries. The model endogenizes the introduction of high standards. Initial differences in income, the nature of capital constraints and transaction costs, the initial production structure and policies and institutions are shown to affect the likelihood of and the size of the high standards economy. Initial differences in some of these same factors—as well as inter-country differences in the distribution of the sizes of farmers—are also shown to determine which producers are included, and which not.
Mathematical modeling of heat transfer during water spray cooling and controlled slow cooling of steel tubes
Creators: name: Mwenifumbo, Steve
Publisher: name: University of British Columbia
Year: 2009

description: Mathematical models were developed which incorporate heat flow, phase transformation kinetics, and temperature and composition dependent thermal-physical properties to predict through-thickness temperature evolution during the manufacturing of steel tubular products under industrial cooling conditions. The two industrial cooling conditions investigated were an 'in-line' water quench, used to control austenite grain growth, and controlled slow cooling, applied at the end of the process to produce the desired microstructure and mechanical properties. This investigation combined computer modeling with laboratory measurements on industrial samples (i.e., AISI 5130 as-rolled steel tubes). A 2-D finite-difference axisymmetric accelerated cooling model (ACM) and a 2-D finite-difference circumferential controlled slow cooling model (CSC) were coded to run on a personal computer. The ACM model can handle multi-stage cooling with varying boundary conditions including radiation, natural convection, and forced convection. The model has the capacity to handle temperature and microstructural dependent thermal-physical properties associated with different phases that can form in the material. The CSC is capable of simulating the effects of tube spacing, forced air-cooling, and various ambient conditions. The basic heat diffusion parts of both the ACM and CSC models, including the routines associated with the liberation of latent heat, were validated against a benchmark commercial FEM software package, ABAQUS™. In addition, the results of the CSC model were verified experimentally by acquiring thermal data from a tube instrumented with thermocouples during the slow cooling of 5130 steel tubes. The CSC model predictions agreed reasonably well with the measured data, capturing the various factors affecting heat-transfer between tubes and their surroundings. A sensitivity analysis conducted with the CSC model indicated that the radiation exchange between different components (e.g., adjacent tubes, tubes and the fume hood, tubes and the floor) plays a significant role in heat-transfer. In addition, several factors influenced the effective emissivity within the model, including loose scale formation on the tubes, geometric assumptions in the model to approximate radiation view factors, and assumptions related to the temperature of the surrounding furnace environment.

description: We develop a general equilibrium households model to analyze the effects of high standards food chains taking seriously into account market imperfections. To measure structural production changes and welfare effects on rural and urban households, our model has two types of agents, five kinds of products and four types of factors. We calibrate the model using dataset from China and do simulations through three ways: increasing world price of high standards food, increasing urban households’ preference for high standards food, and relaxing credit constraints on high standards food production. The simulation results show that how poor households are affected depends on the nature of the shocks leading to the expansion of high standards sector and the market imperfections, and whether the poor can gain through the labor market if they are excluded from high standards farming.

description: Renewable resources are gaining importance in modern society due to their expected positive effects on agriculture, the environment and the economy. To support renewable energy from biomass the EU promotes the cultivation of energy crops. A spatial equilibrium model is applied based on the concept of maximizing net welfare, to provide information whether energy crop production competes with food production for land area and to show the effects of increased biofuel demand on food prices. The Model of Interregional Trade of Energy Crops (ITEC) refers to Eastern Germany and adjacent areas of Poland. Results show that the regions produce enough feedstocks to meet the demand for food and biofuel production. In many cases both food crops and biofuels are either traded on interregional basis or exported to "Rest of Europe" indicating that there is no competition between food and energy crops. The assumed demand shift for biofuels has almost no effect on prices for wheat and rye.

description: By means of the time-dependent density matrix renormalization group algorithm we study the zero-temperature dynamics of the Von Neumann entropy of a block of spins in a Heisenberg chain after a sudden quench in the anisotropy parameter. In the absence of any disorder the block entropy increases linearly with time and then saturates. We analyze the velocity of propagation of the entanglement as a function of the initial and final anisotropies and compare, wherever possible, our results with those obtained by means of Conformal Field Theory. In the disordered case we find a slower (logarithmic) evolution which may signals the onset of entanglement localization.

Tempo/Energia nel pensiero musicale del Novecento

description: During the twentieth century the relationship between music and machines has become increasingly broad and complicated. Composers and musicians are now working within a complex setting of electronic, optic, and acoustic equipment, which results from the original combination between technological research and artistic experimentation. These artifacts are «materialized theories» of sound, because their construction is the concrete result of a specific interpretation of sound and audio, which contributes to determining the horizon of possible manifestations of musical thinking at any given time. They allow us to generate processes which make it possible to amalgamate different representations and effects, organizing the simultaneous presence and live interaction of heterogeneous devices for sound production and control. As a consequence, music materials can no longer be seen as the set of natural and intuitive elements internally processed by an artist. Contemporary musicians, on the contrary, are used to continuously shifting from the symbolic forms of notation for voice and acoustic instruments to electronic sound synthesis, from orchestral practice registers to live interaction using a computer. As part of these processes, action continuously reviews its operating patterns based on a recording of the effects on its performance. Therefore, the universe of the composition is not at all foreordained, but saturated with contingencies; the relationship between the system and its surrounding reality is not established a priori, because changes are based on the analysis of immediate effects. Thus, the preordination dictated by «musical logic» gives way to approximate calculation. For this reason we should acknowledge that the complexity of contemporary media leaves no room for purely textual approaches; on the contrary, in order to understand it, new conceptual tools are called for, to the extent that the equipment used for musical creation is suitable for the logic of systems: it refers not only to sound, but also to the system design itself that generates it which has become an integral part of the work project. The pathway suggested here is aimed at historicizing the development of technologically-driven expression forms, using the notions of time and energy as conceptual guidelines.

description: The new variant famine (NVF) hypothesis postulates that HIV/AIDS is eroding agrarian livelihoods and making rural communities more sensitive and less resilient to drought and other shocks. Although it has not previously been subjected to rigorous econometric testing, NVF has become a high profile but controversial part of the debate on HIV/AIDS and food crises. In this paper, an econometric analysis using panel data from Zambia reveals that HIV/AIDS exacerbates the effects of drought on crop output per hectare among smallholder farming communities in low rainfall areas and where land-to-labor ratios are high. These findings support the NVF hypothesis.

description: The achievement of food security for all remains one of the main development objectives worldwide. Most commonly, non-spatial models are developed for either explaining the underlying determinants of food insecurity and undernourishment or for predicting their changes, so as for identifying vulnerable groups for targeting support. Such approach ignores geographic determinants and the spatial dependency of food security and nutrition outcomes. This paper seeks to address this issue. We use nationally representative data from Guatemala, which faces high and rising rates of undernourishment and child stunting in spite of the efforts engaged on their reduction. Through exploratory spatial data analysis and overlay techniques, some elements embedded in the food system are explored and integrated with the aim of providing complementary information for the analysis of food security. The preliminary results show that these elements are spatially related and that they display geographic trends and spatial dependency. The consideration of these patterns in research and modelling applications can improve the understanding of the related information and its use for the development of food security enhancing strategies. We conclude with recommendations on methodology so as to include spatially explicit analysis in causal or predictive models of food security.

description: With the development of sound production and processing technologies, composers' private rooms stopped delimiting the boundaries of musical creativity, which started inhabiting recording studios instead. Here memory, traditionally entrusted to paper and to the silence of the musical text, met a technology that enabled to record sounds directly, thus achieving the acoustic fulfilment of the composer's thought. The crystalline abstraction of musical notation gave way to a world of sounds submerged in noise as well as in human and technological indeterminacy: it is a world that requires specific control strategies and direct confrontation with performance practices and listening within a complex system. Composers were tossed into this system, becoming performers and active observers of their own work. Thus, the linearity of Shannon’s model of communication was altered. In his works on musical semiology, Jean-Jacques Nattiez had already modified the model from Sender -> Message -> Receiver to Poietic dimension -> Trace

description: In face of climate change and other environmental challenges, inclusion of perennial forage shrubs in Australian agricultural systems has the potential to deliver multiple benefits: increased whole-farm profitability and improved natural resource management. The profitability of shrubs was investigated using MIDAS (Model of an Integrated Dryland Agricultural System), a bio-economic model of a mixed crop/livestock farming system. We found that including forage shrubs could increase farm profitability by over 20% for an optimal 10% of farm area in shrubs. The impact of shrubs on whole-farm profit accrues primarily through the provision of a predictable supply of “out-of-season” feed, thereby reducing supplementary feed costs, and through the deferment of grazing of pastures, allowing a higher stocking rate and improved animal production. The benefits for natural resource management include improved water use through summer-active, deep-rooted plants, reduced risk of soil erosion through year-round ground cover and/or wind breaks, reduced soil acidification, increased habitat for biodiversity, and effective carbon storage. Forage shrubs also allow for the productive use of marginal soils. Finally, we discuss other benefits of shrubs such as the effect on lambing and on livestock gut health. The principles revealed by the MIDAS modelling have wide application beyond the region.

Fat Chance: Modelling the Socio-Economic Determinants of Dietary Fat Intake in China

description: Quantile Regression methods have much to offer the investigation of the determinants of dietary intake. Dietary inadequacy or excess occurs at the tails of nutrient and food intakes, and it seems intuitive that intake responses in these areas will differ from elsewhere along the intake distribution. We apply quantile regression to examine the drivers of a key aspect of dietary health, fat density of energy intake in China. The sample of 2612 individuals between the ages of 20 and 45 is derived from the China Health and Nutrition Survey. The following insights emerge: (i) Fat density increases with income, but worryingly the income effect is more pronounced at the upper conditional tail of fat intake (ii) While it is confirmed that an urban location contributes to higher fat density for the most part, this effect disappears at the upper conditional quantiles, suggesting that, at the most unhealthy levels of fat density conditional on covariates, the problem is as much a rural one as it is urban.

description: We present long-slit spectroscopy of the elliptical galaxy M32, obtained with the 8-m Subaru telescope at Mauna Kea, the 1.5-m Tillinghast telescope at the F. L. Whipple Observatory, and the 4-m Mayall telescope at the Kitt Peak National Observatory. The spectra cover the Lick index red spectral region as well as higher order Balmer lines in the blue. Spectra have been taken with the slit off-set from the nucleus to avoid scattered light contamination from the bright nucleus of M32. An analysis of numerous absorption features, particularly involving the H$γ$ and H$β$ Balmer lines, reveals that systematic radial trends are evident in the integrated spectrum of M32. Population synthesis models indicate a radial change in both the age and chemical composition of the light-weighted mean stellar population in M32, from the nucleus out to 33", i.e., approximately 1.0 effective radius, R_e. Specifically, the light-weighted mean stellar population at 1 R_e is older, by \~3 Gyr, and more metal-poor, by ~-0.25 dex in [Fe/H], t han the central value of ~4 Gyr and [Fe/H]~0.0. We show that this apparent population trend cannot be attributed to a varying contribution from either hot stars or emission line contamination. The increase in age and decrease in metal-abundance with radius are sufficiently well-matched to explain the flat radial color profiles previously observed in M32. In addition, the ratio of Mg to Fe abundance, [Mg/Fe], increases from ~-0.25 in the nucleus to ~-0.08 at 1 R_e. Finally, we find spuriously pronounced line strength gradients in the Mayall data that are an artifact of scattered light from the bright nucleus. Scattered light issues may explain the lack of consistency among previously published studies of radial line strength gradients in M32.
