description: We propose a ``multifractal stress activation'' model combining thermally activated rupture and long memory stress relaxation, which predicts that seismic decay rates after mainshocks follow the Omori law $\sim 1/t^p$ with exponents $p$ linearly increasing with the magnitude $M_L$ of the mainshock and the inverse temperature. We carefully test this prediction on earthquake sequences in the Southern California Earthquake catalog: we find power law relaxations of seismic sequences triggered by mainshocks with exponents $p$ increasing with the mainshock magnitude by approximately $0.1-0.15$ for each magnitude unit increase, from $p(M_L=3) \approx 0.6$ to $p(M_L=7) \approx 1.1$, in good agreement with the prediction of the multifractal model.

description: This article examines the decision of farmers to sell part of their farm output on the market, using data from the Republic of Georgia. A two-level empirical model is used, in which endowments and resource allocation decisions determine farm output and non-farm income, and these in turn determine market participation. We found, as expected, that farm output affects market participation positively, while non-farm income affects it negatively. Landholdings have an indirect positive effect on market participation, through its positive effect on farm output. Education has a negative effect on market participation, mainly through its positive effect on non-farm income.

After analyzing the information obtained in the revision of the literature is noticed that: a) the amount of resources presented by the National System of Rural Credit to the producers and their cooperatives doesn't assist the existent demand and shortage is constituted in an impediment to the maintainable development of the Brazilian agronegócio; b) there is a resistance of the financial agents in granting credit to the cooperatives, due to the existent imperfections in the agricultural market and to the paternalism with that they are driven; c) it is undeniable the importance of the agricultural cooperatives as a connection link between the rural producers and the financial institutions, allowing through capillarity, a larger effectiveness in the individual analysis of the risk of the loans granted to their associates, tends as consequence, the probable reduction of the interest rates collected in these operations, once it would reduce the default risk in the system as a completely.
Thermal Analysis and Design methodology for direct oil-cooled electric motor hairpin end-windings

Publisher: name: Zenodo
Year: 2023

description: Electrification in many industrial sectors, especially in automotive and aerospace, has created a new demand for highly power dense electric motors. This demand has initialized the introduction of different active cooling systems for electric drive systems.The use of oil to actively cool the electric motor end-windings recently gained attention. It largely removes the conductive thermal resistance between the main heat source (windings) and the coolant medium and, therefore, has an attractive cooling potential. Further, oil cooling allows for increased integration of lubrication and cooling systems in electric drive units. Currently, these cooling techniques are being developed mainly by a build-and-test approach, leading to long development times and sub-optimal designs.This research is a collaboration between Bruges Light Vehicle Advanced Engineering Team at Dana Incorporated and the Applied Thermodynamics and Heat Transfer (ATHT) group at Ghent University through a Baekeland-mandate. The goal of the research is to develop a methodology to design electric motors with direct end-winding oil cooling without the need to run time-intensive CFD simulations for each operating point or minor design change, by studying the dominant flow and heat transfer phenomena and extending the existing lower-order end-winding cooling models. Firstly, the physical behaviour of the dominant flow phenomena and thermal processes will be studied by detailed CFD modelling. Secondly, a highly accurate sectorial end-winding mock-up setup will be built to study the oil flow and heat transfer experimentally and validate the CFD models. Subsequently, reduced order convective heat transfer correlations will be derived from a parameter study performed with the validated CFD models. Finally, a thermohydraulic analysis and design methodology will be developed based on a thermal lumped parameter model.
"That’s the way I groove" : repetition and meaning in Ani Difranco’s Evolve
Creators: name: Attas, Robin Elizabeth Sturton
Publisher: name: University of British Columbia
Year: 2009

description: Ani Difranco is a contemporary singer/songwriter who draws musical influence from folk, rock, pop, jazz, and funk to create a unique personal style. Her music employs short, repetitive grooves as the primary means of song structure, while her lyrics explore a broad range of themes and are more poetic than most popular lyrics. This thesis examines three songs from her 2003 album Evolve, "Evolve", "In the Way", and "Slide", which incorporate Difranco's musical idiom of voice and guitar as well as a more expanded instrumentation of lead and backing vocals with a seven-piece band. These songs will facilitate both an exploration of Difranco's music specifically and a consideration of some general analytical issues in popular music. Difranco's musical style suggests a dual analytical focus. The first consideration is the concept of repetition in popular music, manifested most prominently in the repetitive grooves that structure each song. Each groove is examined in isolation for salient qualities that promote or inhibit repetition, and studied in context for instances of variation and development. Changes to the structure of the groove itself, its orchestration, and the interaction between the groove and other musical elements are also considered. The second major focus is text-music relations in popular music: the ways in which a listener's interpretation can be shaped by music and lyrics together. To this end, the lyrics are considered as a poetic object, and all musical parameters (including texture, vocal timbre, meter, hypermeter, pitch form, and the groove). Themes or images in the text may be reinforced by one or more of these musical features, and vice versa. Each of the three song analyses focuses attention on different issues within these two domains. "Evolve," orchestrated for voice and guitar, presents a strongly autotelic groove frequently varied in terms of rhythm, pitch, and timbre for meaningful effect, and also showcases Difranco's diverse range of vocal timbres. "In the Way" is orchestrated for a full band, engaging issues of instrumentation and texture. The discussion will also demonstrate the role of the musical setting in suggesting or reinforcing a certain reading of the lyrics. Finally, "Slide" presents a more varied groove structure in which a linear groove alternates with a homophonic progression, and also recasts repetition, in multiple musical parameters, as an interplay between expectation and reality.

description: We describe a new approach for modeling the transport of high energy particles accelerated during flares from the acceleration region in the solar corona until their eventual thermalization in the flare footpoint. Our technique numerically solves the Fokker-Planck equation and includes forces corresponding to Coulomb collisions in a flux loop with nonuniform ionization, synchrotron emission reaction, magnetic mirroring and a return current electric field. Our solution to the Fokker-Planck equation includes second-order pitch angle and momentum diffusion. It is applicable to particles of arbitrary mass and charge. By tracking the collisions, we predict the bremsstrahlung produced as these particles interact with the ambient stellar atmosphere. This can be compared directly with observations and used to constrain the accelerated particle energy distribution. We have named our numerical code FP and have distributed it for general use. We demonstrate its effectiveness in several test cases.

Periodic orbits and semiclassical form factor in barrier billiards

description: Using heuristic arguments based on the trace formulas, we analytically calculate the semiclassical two-point correlation form factor for a family of rectangular billiards with a barrier of height irrational with respect to the side of the billiard and located at any rational position p/q from the side. To do this, we first obtain the asymptotic density of lengths for each family of periodic orbits by a Siegel-Veech formula. The result K(0)=1/2+1/q obtained for these pseudo-integrable, non-Veech billiards is different but not far from the value of 1/2 expected for semi-Poisson statistics and from values of K(0) obtained previously in the case of Veech billiards.

description: ML decision-aid systems are increasingly common on the web, but their successful integration relies on people trusting them appropriately: they should use the system to fill in gaps in their ability, but recognize signals that the system might be incorrect. We measured how people's trust in ML recommendations differs by expertise and with more system information through a task-based study of 175 adults. We used two tasks that are difficult for humans: comparing large crowd sizes and identifying similar-looking animals. Our results provide three key insights: (1) People trust incorrect ML recommendations for tasks that they perform correctly the majority of the time, even if they have high prior knowledge about ML or are given information indicating the system is not confident in its prediction; (2) Four different types of system information all increased people's trust in recommendations; and (3) Math and logic skills may be as important as ML for decision-makers working with ML recommendations.

AbstractViltolarsen (Viltepso® in Japan) is a phosphorodiamidate morpholino antisense oligonucleotide being developed by Nippon Shinyaku, in collaboration with the National Center of Neurology and Psychiatry (NCNP), for the treatment of Duchenne muscular dystrophy (DMD). Viltolarsen binds to exon 53 of the dystrophin mRNA precursor and restores the amino acid open-reading frame by skipping exon 53, resulting in the production of a shortened dystrophin protein that contains essential functional portions. In March 2020, intravenous viltolarsen received its first global approval in Japan for the treatment of DMD in patients with confirmed deletion of the dystrophin gene that is amenable to exon 53 skipping. Viltolarsen is under regulatory review in the USA and clinical trials continue in the USA, Canada and globally. This article summarizes the milestones in the development of viltolarsen leading to the first approval for DMD.

description: In this paper, a five-probe method of sheet resistance measurement that is independent of probe positions is reported. The method is strict for an infinite homogeneous plane. It has potential applications as a sheet resistance standard based on planar molecular layers. The method can be used to measure the sheet resistance of layers covering objects with a spherical topology, particularly on micro- and nanometric scales, where it is difficult to control probe positioning.

description: The Coronavirus pandemic has created complex challenges and adverse circumstances. This research discovers public sentiment amidst problematic socioeconomic consequences of the lockdown, and explores ensuing four potential sentiment associated scenarios. The severity and brutality of COVID-19 have led to the development of extreme feelings, and emotional and mental healthcare challenges. This research identifies emotional consequences - the presence of extreme fear, confusion and volatile sentiments, mixed along with trust and anticipation. It is necessary to gauge dominant public sentiment trends for effective decisions and policies. This study analyzes public sentiment using Twitter Data, time-aligned to COVID-19, to identify dominant sentiment trends associated with the push to 'reopen' the economy. Present research uses textual analytics methodologies to analyze public sentiment support for two potential divergent scenarios - an early opening and a delayed opening, and consequences of each. Present research concludes on the basis of exploratory textual analytics and textual data visualization, that Tweets data from American Twitter users shows more trust sentiment support, than fear, for reopening the US economy. With additional validation, this could present a valuable time sensitive opportunity for state governments, the federal government, corporations and societal leaders to guide the nation into a successful new normal future.

description: Wave fields obeying the 2D Helmholtz equation on branched surfaces (Sommerfeld surfaces) are studied. Such surfaces appear naturally as a result of applying the reflection method to diffraction problems with straight scatterers bearing ideal boundary conditions. This is for example the case for the classical canonical problems of diffraction by a half-line or a segment. In the present work, it is shown that such wave fields admit an analytical continuation into the domain of two complex coordinates. The branch sets of such continuation are given and studied in detail. For a generic scattering problem, it is shown that the set of all branches of the multi-valued analytical continuation of the field has a finite basis. Each basis function is expressed explicitly as a Green's integral along so-called double-eight contours. The finite basis property is important in the context of coordinate equations, introduced and utilised by the authors previously, as illustrated in this article for the particular case of diffraction by a segment.

description: We investigate the migration rates of high-mass protoplanets embedded in accretion discs via two and three-dimensional hydrodynamical simulations. The simulations follow the planet's radial motion and employ a nested-grid code that allows for high resolution close to the planet. We concentrate on the possible role of the coorbital torques in affecting migration rates. We analyse two cases: (a) a Jupiter-mass planet in a low-mass disc and (b) a Saturn-mass planet in a high-mass disc. Planet migration in case (b) is much more susceptible to coorbital torques than in case (a). We find that the coorbital torques in both cases do not depend sensitively on whether the planet is allowed to migrate through the disc or is held on a fixed orbit. We also examine the dependence of the planet's migration rate on the numerical resolution near the planet. For case (a), numerical convergence is relatively easy to obtain, even when including torques arising from deep within the planet's Hill sphere. The migration rate in this case is numerically on order of the Type II migration rate and much smaller than the Type I rate, if the disc has 0.01 solar-masses inside 26 AU. Torques from within the Hill sphere provide a substantial opposing contribution to the migration rate. In case (b), the gas mass within the Hill sphere is larger than the planet's mass and convergence is more difficult to obtain. If the torques within the Hill sphere are ignored, convergence is more easily achieved but the migration rate is artificially large. At our highest resolution, the migration rate for case (b) is much less than the Type I rate, but somewhat larger than the Type II rate.

description: No início do século XXI, notadamente os EUA e UE discutem e promovem o uso de políticas específicas de estímulo à substituição de combustíveis fósseis por fontes renováveis de origem de biomassa. No Brasil desde os anos 70 a produção do etanol representa uma alternativa ecológica geradora de emprego e renda. A produção de etanol brasileira, de baixo custo e alta produtividade, dadas as vantagens existentes junto aos recursos naturais e mão de obra, é destinada principalmente para o mercado norte americano e o mercado europeu. O objetivo geral deste estudo é obter a previsão de produção do etanol brasileiro para exportação entre 2007-2010 através de uma aplicação de Vetores Auto-Regressivos (VAR), a partir das variáveis captadas pelo modelo Mundell-Fleming, Produto Interno Bruto Agropecuário, taxa de juros, câmbio, preço e exportações do etanol. Os resultados apontam para uma tendência crescente de produção iniciada em 2006. A taxa de crescimento da produção prevista de etanol brasileiro para exportação entre 2007-2010 situa-se na ordem de 44,89%.----------------------------------------------Since the beginning of the 21st century, especially the USA and EU have been discussing and promoting the use of specific incentive politics to substitute fossil fuels for renewable sources of biomass origin. In Brazil since the seventies the production of ethanol has been representing an ecological alternative generating employment and income. The production of Brazilian ethanol, of low cost and high productivity, given the existent advantages combined with the natural resources and manual work, is destined mainly for the North American and the European market. The general objective of this study is to obtain the forecast of Brazilian ethanol production for export in the 2007-2010 period through an application of Vector Auto Regression Analysis (VAR), starting from the variables captured by the Mundell-Fleming model, the agricultural gross domestic product, interest rate, exchange, price and ethanol exports. The results appear to have a tendency of growth for the production initiated in 2006. The growth rate of the foreseen Brazilian ethanol production of Brazilian for the export from 2007 to 2010 is about 44.89%.

description: There is abundant evidence that heating processes in the central regions of elliptical galaxies has both prevented large-scale cooling flows and assisted in the expulsion of metal rich gas. We now know that each such spheroidal system harbors in its core a massive black hole weighing approximately 0.13% of the mass in stars and also know that energy was emitted by each of these black holes with an efficiency exceeding 10% of its rest mass. Since, if only 0.5% of that radiant energy were intercepted by the ambient gas, its thermal state would be drastically altered, it is worth examining in detail the interaction between the out-flowing radiation and the equilibrium or inflowing gas. On the basis of detailed hydrodynamic computations we find that relaxation oscillations are to be expected with the radiative feedback quite capable of regulating both the growth of the central black hole and also the density and thermal state of the gas in the galaxy. Mechanical input of energy by jets may assist or dominate over these radiative effects. We propose specific observational tests to identify systems which have experienced strong bursts of radiative heating from their central black holes.

description: Background: Resonance scattering has been extensively used to study the structure of exotic, neutron-deficient nuclei. Extension of the resonance scattering technique to neutron-rich nuclei was suggested more than 20 years ago. This development is based on the isospin conservation law. In spite of broad field of the application, it has never gained a wide-spread acceptance. Purpose: To benchmark the experimental approach to study the structure of exotic neutron-rich nuclei through resonance scattering on a proton target. Method: The excitation function for p+8Li resonance scattering is measured using a thick target by recording coincidence between light and heavy recoils, populating T=3/2 isobaric analog states (IAS) in 9Be. Results: A good fit of the 8Li(p,p)8Li resonance elastic scattering excitation function was obtained using previously tentatively known 5/2- T=3/2 state at 18.65 MeV in 9Be and a new broad T=3/2 s-wave state - the 5/2+ at 18.5 MeV. These results fit the expected iso-mirror properties for the T=3/2 A=9 iso-quartet. Conclusions: Our analysis confirmed isospin as a good quantum number for the investigated highly excited T=3/2 states and demonstrated that studying the structure of neutron-rich exotic nuclei through IAS is a promising approach.

description: We present a large-scale study of the IC1396 region using new deep NIR and optical images, complemented by 2MASS data. For ten globules in IC1396 we determine (H-K, J-H) colour-colour diagrams and identify the young stellar population. Five of these globules contain a rich population of reddened objects, most of them probably young stellar objects. Two new HH objects (HH865 and HH864) could be identified by means of [SII] emission, one of them a parsec-scale flow. Using star counts based on 2MASS data we create an extinction map of the whole region. This map is used to identify 25 globules and to estimate their mass. The globule masses show a significant increase with the distance from the exciting O6.5V star HD206267. We explain this correlation by the enhanced radiation pressure close to this star, leading to evaporation of the nearby clouds and hence smaller globule masses. We see evidence that the radiation from HD206267 has a major impact on the star formation activity in these globules.

description: We report on magnetization experiments from which we obtain the field-induced kinetic energy density, $E_k$, in the superconducting phase of several Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ single crystal samples. The kinetic energy magnitude changes according to the characteristic reduction of the single-electron density of states produced by the pseudogap in the underdoped limit. Moreover, a remarkable peak of $E_k$ occurring at the specific holes density $p\sim0.18$ is related to a van Hove singularity due to the pseudogap closure. We also extracted the superfluid density, $ρ_s$. We conclude that $E_k$ and $ρ_s$ are related to the pseudogap energy scale. This result is understood as an evidence of the coexistence between superconductivity and the pseudogap phenomenon in the Bi$_2$Sr$_2$CaCu$_2$O$_{8+δ}$ cuprate compound.

description: This paper analyzes how the market interventions of the Serbian government during the food crisis 2007/2008, inter alia a de facto export ban, have affected domestic wheat markets. Besides a comprehensive description of the crisis policy and its effects on the Serbian wheat market, we investigate how it influences the equilibrium and stability of the Serbian wheat market and its integration with the world market within a price transmission model. Applying a Markov-switching error correction model to weekly wheat grower prices in Serbia and world market prices, two states of the wheat market are identified. Our results suggest that although the long-run price elasticity did not change during the crisis, the market equilibrium was disrupted and the market stability reduced. Also, we find that the price dampening effect of the export restrictions was only short-lived, and that Serbian wheat grower prices even increased above the world market level.

Subjects: Astrophysics

description: Fundamentally for the extended disc region of a spiral galaxy, an alternative solution to Laplace equation has been presented for a potential that is radially symmetric on the disc plane. This potential, unlike newtonian one, is shown to be logarithmic in distance from the centre, which allows for the rotation velocity to be constant along the disc radius. It is also shown that this potential easily manifests into a relationship between inner mass of the galaxy and terminal rotation velocity, which has been empirically observed and known as Baryonic Tully-Fisher relations.

description: Modern JavaScript includes the SharedArrayBuffer feature, which provides access to true shared memory concurrency. SharedArrayBuffers are simple linear buffers of bytes, and the JavaScript specification defines an axiomatic relaxed memory model to describe their behaviour. While this model is heavily based on the C/C++11 model, it diverges in some key areas. JavaScript chooses to give a well-defined semantics to data-races, unlike the "undefined behaviour" of C/C++11. Moreover, the JavaScript model is mixed-size. This means that its accesses are not to discrete locations, but to (possibly overlapping) ranges of bytes. We show that the model, in violation of the design intention, does not support a compilation scheme to ARMv8 which is used in practice. We propose a correction, which also incorporates a previously proposed fix for a failure of the model to provide Sequential Consistency of Data-Race-Free programs (SC-DRF), an important correctness condition. We use model checking, in Alloy, to generate small counter-examples for these deficiencies, and investigate our correction. To accomplish this, we also develop a mixed-size extension to the existing ARMv8 axiomatic model. Guided by our Alloy experimentation, we mechanise (in Coq) the JavaScript model (corrected and uncorrected), our ARMv8 model, and, for the corrected JavaScript model, a "model-internal" SC-DRF proof and a compilation scheme correctness proof to ARMv8. In addition, we investigate a non-mixed-size subset of the corrected JavaScript model, and give proofs of compilation correctness for this subset to x86-TSO, Power, RISC-V, ARMv7, and (again) ARMv8, via the Intermediate Memory Model (IMM). As a result of our work, the JavaScript standards body (ECMA TC39) will include fixes for both issues in an upcoming edition of the specification.

description: In this paper we study the optimal forest conservation policy by a hyperbolically discounting society. Society comprises a series of non-overlapping imperfectly altruistic generations each represented by its own government. Under uncertainty about future pay-offs we determine, as solution of an intergenerational dynamic game, the optimal timing of irreversible harvest. Earlier harvest occurs and the option value attached to the forest clearing decision is eroded under both the assumptions of naïve and sophisticated belief about future time-preferences. This results in a bias toward the current generation gratification which affects the intergenerational allocation of benefits and costs from harvesting and conserving a natural forest.

description: The glass transition temperature (Tg) is the temperature, after which the supercooled liquid undergoes a dynamical arrest. Usually, the glass network modifiers (e.g., Na2O) affect the behavior of Tg. However, in aluminosilicate glasses, the effect of different modifiers on Tg is still unclear and show an anomalous behavior. Here, based on molecular dynamics simulations, we show that the glass transition temperature decreases with increasing charge balancing cations field strength (FS) in the aluminosilicate glasses, which is an anomalous behavior as compared to other oxide glasses. The results show that the origins of this anomaly come from the dynamics of the supercooled liquid above Tg, which in turn is correlated to pair excess entropy. Our results deepen our understanding of the effect of different modifiers on the properties of the aluminosilicate glasses.

description: We propose a kinetic theory of transport in metals embedded with ferromagnetic nanoclusters, describing the dependence of the form of magnetoresistance on anisotropy characteristics of the ensemble of clusters and the influence of the electron spin depolarisation by clusters. We note that this effect is strongest when all the clusters have the same intrinsic easy-axis anisotropy.

description: The objective of this paper is to measure productive efficiency of irrigation water efficiency based on the concept of technical efficiency and compared among different sizes farms in Tunisia. The proposed methodology is applied to a randomly selected sample of 144 citrus growing farms and differentiated by size (small, medium and large farms). A stochastic production frontier approach, based on Battese and Coelli’s (1995) inefficiency effect model, is used to obtain farm-specific estimates of technical and irrigation water efficiency. The last step of the analysis consists on the identification of the factors influencing irrigation water efficiency differentials across citrus growing farms. Empirical results show that estimated mean technical efficiency ranges from a minimum of 12.82% to a maximum of 90.69% with an average estimate of 67.73%. This result means that 32.3% increase in production is possible with the present state of technology and unchanged input uses, if technical inefficiency is completely removed. Thus, improving technical efficiency will result to significant increases in framer’s revenue and profit. On the other hand, mean irrigation water efficiency is found to be 53%, which is much lower than technical efficiency and also exhibits greater variability ranging from 1.6% to 98.87%. Estimated mean irrigation water efficiency implies that the observed quantity of marketable citrus could have been maintained by using the observed values of other inputs while using 47.0% less of irrigation water. This means that farmer’s can achieve significant savings in water use by improving irrigation system technologies.
Speech audiometry in Cantonese and other non-native English speakers : the use of digits and Cantonese words as stimuli
Creators: name: Siu, Carrie K
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of the present study was to investigate validity and accuracy issues with the use of English speech audiometry on non-native English speakers. Two widely used tests of speech audiometry, Speech Recognition Threshold (SRT) and Word Recognition Score (WRS) were measured on 45 participants with English as a non-native language. The effects of test stimuli (English words versus English digits versus Cantonese words) and the correlations between language background factors (length of residence, age of exposure, years of instruction, birthplace, first language, preferred language, home language, daily language use, English TV and internet use) and the performance of SRT and WRS were analyzed. English digit pairs were found to be a more accurate measure of hearing threshold for English speech than English words, but Cantonese words elicited the lowest audiometric thresholds from the Cantonese-speaking participants. Age and birthplace were found to significantly correlate with the extent to which speech audiometric performance will be affected by the language of test stimuli. An analysis of the differences in English and Cantonese speech acoustic spectra was provided, and the implication that hearing levels measured using English speech-based stimuli might not reflect real life impairment for non-native English speakers was discussed. Clinical implications include being cautious in applying test results to real life impairment for non-native English-speaking clients, so as to avoid over-estimating the need for amplification and misdiagnosis of the nature of hearing loss. When administering speech audiometry on non-native English speakers, familiarization to test materials before SRT testing, the use of digit pairs as SRT stimuli, and the use of subjective questionnaires to assess listening need and impairment are recommended.
