description: Tropical cyclones (TCs) cause devastating damage to life and property. Historical TC data is scarce, complicating adequate TC risk assessments. Synthetic TC models are specifically designed to overcome this scarcity. While these models have been evaluated on their ability to simulate TC activity, no study to date has focused on model performance and applicability in TC risk assessments. This study performs the intercomparison of four different global-scale synthetic TC datasets in the impact space, comparing impact return period curves, probability of rare events, and hazard intensity distribution over land. We find that the model choice influences the costliest events, particularly in basins with limited TC activity. Modelled direct economic damages in the North Indian Ocean, for instance, range from 40 to 246 billion USD for the 100-yr event over the four hazard sets. We furthermore provide guidelines for the suitability of the different synthetic models for various research purposes.

description: We consider cyclic Lotka-Volterra models with three and four strategies where at every interaction agents play a strategy using a time-dependent probability distribution. Agents learn from a loss by reducing the probability to play a losing strategy at the next interaction. For that, an agent is described as an urn containing $β$ balls of three respectively four types where after a loss one of the balls corresponding to the losing strategy is replaced by a ball representing the winning strategy. Using both mean-field rate equations and numerical simulations, we investigate a range of quantities that allow us to characterize the properties of these cyclic models with time-dependent probability distributions. For the three-strategy case in a spatial setting we observe a transition from neutrally stable to stable when changing the level of discretization of the probability distribution. For large values of $β$, yielding a good approximation to a continuous distribution, spatially synchronized temporal oscillations dominate the system. For the four-strategy game the system is always neutrally stable, but different regimes emerge, depending on the size of the system and the level of discretization.

description: There is much debate on how social values should influence scientific research. However, the question of practical applicability of philosophers’ normative proposals has received less attention. Here, we test the attainability of Matthew J. Brown’s (2020) Moral Imagination ideal (MI ideal), which aims to help scientists to make warranted value-judgements through reflecting on goals, options, values, and stakeholders of research. Here, the tools of the MI ideal are applied to a climate modelling setting, where researchers are developing aerosol-cloud interaction (ACI) parametrizations in an Earth System Model with the broader goal of improving climate sensitivity estimation. After the identification of minor obstacles to applying the MI ideal, we propose two ways to increase its applicability. First, its tools should be accompanied with more concrete guidance for identifying how social values enter more technical decisions in scientific research. Second, since research projects can have multiple goals, examining the alignment between broader societal aims of research and more technical goals should be part of the tools of the MI ideal.
title: Investigation of entropy generation and thermohydraulics of forced and mixed convection of Al₂O₃-Cu/water in a parabolic trough receiver tube
Creators: name: Khfagi, Amir Mohamed Ibrahim
Publisher: name: University of Glasgow
Year: 2023

description: Heat transfer has long been a vital part of human life. Many sources have focused on increased heat transfer. Various industries, such as solar water heating systems, solar chemistry, solar desalination plants, and concentrating solar power plants, food processing plants, petrochemical plants, refrigeration systems and air conditioning equipment, and condensing central heating exchangers, etc., face the challenges of effective utilisation, conservation, and recovery of heat. In modern times, increasing the rate of heat transfer in concentrating solar collectors such as parabolic troughs by using various passive approaches have proven to be very effective. When passive approaches are used, more pumping power is needed to move the fluid through the receiver. Manufacturing of parabolic trough receiver tubes requires a significant financial commitment due to the high expenses of both capital and operation. Therefore, it is essential to develop parabolic trough receivers that are efficient. Several methods, such as heat transfer enhancement and minimisation of entropy generation, are used to do this. The current investigation makes use of tube insert technology and nanoparticle flow to achieve optimal thermohydraulic and thermodynamic designs.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: The electron cyclotron resonance (ECR) plasmaoxidation and thermal oxidation mechanisms for germanium were investigated using in situspectroscopic and single wavelength ellipsometry. ECR plasmaoxidation was performed at substrate temperatures of 80–400 °C while thermal oxidations were performed between 400 and 600 °C. Optical modeling shows that there is an interface between the oxide film and the substrate that is composed of germanium oxide and amorphousgermanium.Fourier transform infrared and x‐ray photoelectron spectroscopy data confirm that the oxides resulting from thermal and ECR plasmaoxidation are GeO2. The real time oxidation analysis shows that both kinds of oxidation of Ge follow linear‐parabolic kinetics, and yield temperature activated transport. The activation energy for ECR plasmaoxidation is about one order smaller than that of thermal oxidation. This indicates different oxidation species. Less charge was formed at the interface for ECR plasma oxides.

description: The nucleation and initial growth of Si films is fundamental to the understanding and control of rapid thermal chemical vapor deposition (RTCVD), and plasma enhanced CVD(PECVD) processes. Herein is reported the nucleation and growth of Si deposited on oxidized silicon wafers by electron cyclotron resonance (ECR) PECVD in the 600–700 °C temperature range, under low pressures, and using both in situspectroscopicellipsometry and single wavelength real‐time ellipsometry. An island growth and coalescence model is used to interpret the real‐time ellipsometry data. Initial nuclei distance and growth parameters are derived. Atomic force microscopy was used to observe the early stage of nucleation. In situspectroscopicellipsometry is used to measure the final Si film thicknesses and optical properties. The deposited Si films were characterized by cross‐sectional transmission electron microscopy.

description: The dependence of the Si/SiO2interfacecharacteristics on the thickness and oxidation temperature for SiO2filmsgrown on different Si orientations was studied by spectroscopic immersion ellipsometry (SIE) and atomic force microscopy(AFM). Essentially, SIE uses liquids that match the refractive index of the films, thereby optically removing the films and consequently increasing the sensitivity to the interface. We show that as the thickness of the thermally grown SiO2 overlayer increases, the thickness of the suboxide layer at the interface also increases, and the average radius of the crystalline silicon protrusions (roughness) at the interface decreases for the three different Si orientations (100), (110), and (111), and two different oxidation temperatures (800 and 1000 °C) studied. The dependence of the interface roughness on the thickness of the SiO2 overlayer was confirmed by AFM. The results include unintentionally and intentionally roughened Si samples and are shown to be consistent with the commonly accepted Si oxidation model.

Irrigation and the Origins of the Southern Moche State on the North Coast of Peru
Creators: name: Billman, Brian
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2002

description: In this paper, I examine the role that irrigation played in the formation of the Southern Moche state in the Moche Valley, Peru. Specifically, I attempt to test Wittfogel and Steward's hydraulic model, which postulates that in certain arid environments, the managerial requirements of construction and maintenance of irrigation systems played a crucial role in the formation of centralized polities. I formulate and evaluate four hypotheses concerning the role of irrigation systems in the Moche Valley. Those hypotheses are then evaluated using settlement pattern data drawn from two surveys that cover the entire coastal section of the valley and provide information on 910 archaeological sites. Based on those data, I present a sequence of political development for the valley from the formation of the first autonomous village in the Late Preceramic period (2500–1800 B. C.) to the zenith of the Southern Moche state. Evaluation of the four hypotheses indicates that the managerial requirements of irrigation were relatively unimportant; rather, warfare, highland-coastal interaction, and political control of irrigation systems created opportunities for leaders to form a highly centralized, territorially expansive state sometime between A. D. 200 and 700.

description: A large amount of numerically-oriented code is written and is being written in legacy languages. Much of this code could, in principle, make good use of data-parallel throughput-oriented computer architectures. Loo.py, a transformation-based programming system targeted at GPUs and general data-parallel architectures, provides a mechanism for user-controlled transformation of array programs. This transformation capability is designed to not just apply to programs written specifically for Loo.py, but also those imported from other languages such as Fortran. It eases the trade-off between achieving high performance, portability, and programmability by allowing the user to apply a large and growing family of transformations to an input program. These transformations are expressed in and used from Python and may be applied from a variety of settings, including a pragma-like manner from other languages.

Trade Liberalization, Deindustrialization, and Inequality: Evidence from Middle-Income Latin American Countries
Creators: name: Bogliaccini, Juan Ariel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: This article explores the relationship among trade liberalization, deindustrialization, and income inequality in the more industrially advanced Latin American countries. It argues that, among the most important liberal reforms implemented during the 1980s and 1990s, trade reform was especially detrimental to equality because it accelerated deindustrialization. The analysis provides evidence to support this mechanism. Therefore, as the liberalization of trade increased, the deindustrialization process produced an increase in inequality. In short, evidence shows how the process of economic integration to the global market, as it took place, produced an increase in inequality through the destruction of formal employment. Resumen: Este artículo explora la relación entre la liberalización del comercio, la desindustrialización y la desigualdad en el grupo de países con mayor desarrollo industrial relativo en América Latina. El artículo argumenta que, entre las reformas liberalizadoras más importantes llevadas a cabo en la región entre las décadas de 1980 y 1990, la liberalización del comercio fue especialmente nociva para la equidad de ingresos mediante la aceleración del proceso de desindustrialización. El análisis provee evidencia sobre este mecanismo. Entonces, mientras la liberalización del comercio avanzaba, el proceso de desindustrialización produjo un incremento en la desigualdad de ingreso. La evidencia sugiere que el proceso de integración al mercado global, del modo en que se llevó adelante, produjo un incremento en la desigualdad a través de la destrucción del empleo formal.

Inclined Gas Disks in the Lenticular Seyfert Galaxy NGC 5252

Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: We discuss the morphology and kinematics of the extended gas in the type 2 Seyfert galaxy NGC 5252 based on Hubble Space Telescope (HST) WFPC2 continuum and emission-line images (including a new [O III] λ5007 image) and a ground-based Fabry-Perot (F-P) velocity map of the ionized gas. The fine-scale morphology of the ionized gas in this galaxy's very extended (~40 kpc) ionization bicone consists of a complex network of filamentary strands. The new WFPC2 [O III] image also reveals more detail in the circumnuclear (~3 kpc) gas disk than is seen in the Hα + [N II] image presented previously by Tsvetanov and coworkers. The F-P velocity map shows an obvious antisymmetry of the velocity field of the ionized gas across the nucleus. We conclude that there are three dynamical components to the extended gas in NGC 5252. Two of these components are gas disks aligned with the stellar disk, one rotating with the stars and the other counterrotating. The third component is the circumnuclear gas disk seen in the HST observations and its extension to larger scales; this disk has an inclination of ~40° and a kinematic major axis in P.A. ~ 90°-135°, some 80°-125° from the major axis of the stellar disk. This simple model of two inclined rotating disks, superposed along the line of sight, describes well the seemingly complex kinematics observed in the optical emission lines and the H I 21 cm radio maps. The large misalignment between the second disk and the stellar disk suggests that the gas distribution, and possibly the nuclear activity, in NGC 5252 may have resulted from a galaxy merger event. The absence of significant radial motions, together with the well-defined ionization cones, strongly suggests that the gas is photoionized by a compact nuclear source rather than being ionized in situ by shock waves in a large-scale outflow.

title: Drawing as a tool for thought: The development of the ability to use drawing as a design tool amongst children aged 6 - 8 years
Creators: name: Hope, Gillian
Publisher: name: Goldsmiths, University of London
Year: 2004

description: My research into young children's understanding of using drawing to support designing was undertaken in a rural First School (children aged 5-9 years) across the years 1998-2002. Since little previous research had been conducted in the field, the first phase of the research aimed to discover how young children could use drawing to support designing, through analysing drawings produced in Design and Technology lessons. It appeared that below age 8, although children could record design ideas, they did not use drawing to support their design thinking or develop their ideas towards making. Understandings gained through reading, led to the belief that the metaphor of design drawing as both a Container and a Journey could be used to teach younger children to use drawing as a design tool. The second phase of the research, therefore, involved devising a Programme of four school term's duration, for a Year 2 class (average age 6.10 at start of Programme), that embedded the Container I Journey metaphor. These children's developing capability with design drawing was compared at intervals with that of a parallel class who did not receive the Programme. The evaluation of the Programme used both qualitative and quantified analysis to assess both process and products of using drawing to support designing. The analysis instrument for the products was based on a holistic view of the design process, placing Understanding the Purpose of the Drawing at the centre of capability and Dimensions of Design Drawing through which such capability were expressed in drawing as emanating from this central understanding. Besides demonstrating the success of the Programme, the analysis showed how children adapt their use of drawing for different activities (problem-solving or product design) and revealed the importance of discussion whilst drawing for the development of viable design ideas.
Accretional Heating of Asymmetric Supernova Cores
Creators: name: Thompson, Christopher
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2000

description: The role of accretion in heating a stalled bounce shock in a core-collapse supernova is investigated. We show that effective accretional heating causes an asymmetric expansion of the shock, sufficient to impart a net impulse of ~300-400 km s-1 to the neutron core. To simplify the analysis, we consider a failed accretion shock. Below such a shock, inward advection is faster than neutrino heating and the usual gain criterion does not suffice to determine a successful explosion. A mechanism that enhances buoyancy and inhibits mixing between hot and cold postshock fluid elements is required to revive the shock. We focus on the response of a magnetic field to the accretion flow. Ram heating and shearing of a low-density, magnetized fluid phase ("M-fluid") is shown to be faster than neutrino cooling. The long duration of the accretion flow compared with the dynamical time allows for a large amplification of the magnetic energy. We calculate the stability of a spherical shock in the presence of a low-density hydrostatic atmosphere below it and show that below a critical atmospheric density the shock is unstable to a global Rayleigh-Taylor mode. We then calculate the equilibrium structure of this Rayleigh-Taylor plume as it accumulates energy and the critical size beyond which quasi-static expansion is no longer possible and its outer boundary converts to a running shock. Accretion continues while the shock expands, and an energy of ~1051 ergs is a direct consequence of the efficiency of ram heating close to the neutron core. The linear momentum imparted to the core is directly related to the mass profile of the precollapse core and explains the proper motions of (most) radio pulsars. We also estimate the net circulation imparted to the last 0.1-0.2 M☉ of collapsing material, which appears sufficient to torque the core down to a spin period of 1-100 ms. The effect of photodissociation on the shock jump conditions is calculated, and the implications for nucleosynthesis of iron peak elements are considered. Finally, the residual magnetic field advected out into the eventual supernova remnant is compared with the field generated by a rapidly spinning neutron star.

On the Central Charge of Spacetime Current Algebras and Correlators in String Theory on AdS3

description: Spacetime Virasoro and affine Lie algebras for strings propagating in AdS3 are known to all orders in $α'$. The central extension of such algebras is a string vertex, whose expectation value can depend on the number of long strings present in the background but should be otherwise state-independent. In hep-th/0106004, on the other hand, a state-dependent expectation value was found. Another puzzling feature of the theory is lack of cluster decomposition property in certain connected correlators. This note shows that both problems can be removed by defining the free energy of the spacetime boundary conformal field theory as the Legendre transform of the formula proposed in the literature. This corresponds to pass from a canonical ensemble, where the number of fundamental strings that create the background can fluctuate, to a microcanonical one, where it is fixed.

description: The giant flare of 1998 August 27 from SGR 1900+14 was extraordinary in many ways: it was the most intense flux of gamma rays ever detected from a source outside our solar system; it was longer than any previously detected burst from a soft gamma repeater (SGR) in our Galaxy by more than an order of magnitude; and it showed a remarkable four-peaked, periodic pattern in hard X-rays with the same rotation period that was found modulating soft X-rays from the star in quiescence. The event was detected by several gamma-ray experiments in space, including the Ulysses gamma-ray burst detector and the BeppoSAX Gamma-Ray Burst Monitor. These instruments operate in different energy ranges, and comparisons of their measurements reveal complex patterns of spectral evolution as the intensity varies. In this paper, we present a joint analysis of the BeppoSAX and Ulysses data and discuss some implications of these results for the SGRs. We also present newly analyzed Venera/SIGNE and ISEE-3 data on the 1979 March 5 giant flare from an SGR in the Large Magellanic Cloud (SGR 0526-66) and compare them with the August 27 event. Our results are consistent with the hypothesis that giant flares are due to catastrophic magnetic instabilities in highly magnetized neutron stars, or "magnetars." In particular, observations indicate that the initial hard spike involved a relativistic outflow of pairs and hard gamma rays, plausibly triggered by a large propagating fracture in the crust of a neutron star with a field exceeding 1014 G. Later stages in the light curve are accurately fitted by a model for emission from the envelope of a magnetically confined pair-photon fireball, anchored to the surface of the rotating star, which contracts as it emits X-rays and then evaporates completely in a finite time. The complex four-peaked shape of the light curve likely provides the most direct evidence known for a multipolar geometry in the magnetic field of a neutron star.

description: We report the results of a coherent study of a new class of halo stars defined on the basis of the chemical compositions of three metal-poor objects ([Fe/H] -2) that exhibit unusually low abundances of α-element (Mg, Si, Ca) and neutron-capture (Sr, Y, Ba) material. Our analyses confirm and expand on earlier reports of atypical α- and neutron-capture abundances in BD +80°245, G4-36, and CS 22966-043. We also find that the latter two stars exhibit unusual relative abundance enhancements within the iron peak (Cr, Mn, Ni, Zn), along with what may be large abundances of Ga, an element not previously reported as being observed in any metal-poor star. These results provide further evidence that chemical enrichment and star formation histories varied from region to region within the Milky Way halo. Comparing the chemical abundances of the newly identified stellar population to supernova model yields, we derive supernova ratios of Type Ia versus Type II events in the range of 0.6 (NIa/NII)New Pop 1.3. For the Sun, we derive 0.18 ± 0.01 < (NIa/NII)☉ < 0.25 ± 0.06, supernova ratios in good agreement with values found in the literature. Given the relatively low metallicity and relatively high NIa/NII ratios of the low-α stars studied here, these objects may have been born from material produced in the yields of the earliest Type Ia supernova events. We also report the results of a preliminary attempt to employ the observed chemical abundances of low-metallicity stars in the identification, and possible cosmic evolution, of Type Ia supernova progenitors, and we discuss the limitations of current model yields.

Does an NeNa Cycle Exist in Explosive Hydrogen Burning?

description: According to common assumptions, matter in the mass range A ≥ 20 is processed through the so-called NeNa cycle during hydrogen-burning nucleosynthesis. The existence of such a reaction cycle implies that the (p, α) reaction on 23Na is more likely to occur than the competing (p, γ) reaction. However, recently evaluated thermonuclear rates for both reactions carry relatively large uncertainties and allow for both possibilities, i.e., a "closed" and an "open" NeNa cycle. We measured the 23Na(p, γ)24Mg reaction at the Laboratory for Experimental Nuclear Astrophysics. The present experimental results, obtained with our sensitive γ-ray detection apparatus, reduce the 23Na + p reaction rate uncertainties significantly. We demonstrate that a closed NeNa cycle does not exist at stellar temperatures of T = 0.2-0.4 GK. The new results have important implications for the nucleosynthesis in classical novae, including the amount of 26Al ejected by the thermonuclear explosion, the elemental abundances of Mg and Al observed in nova shells, and observations of Mg and Al isotopic ratios in primitive meteorites.

description: A successful space mission depends on crucial systems and teams working together. Designing a feasible trajectory for the spacecraft that satisfies the goals of the mission, accurately conducting simulations on a digital twin to control the health and fluidity of operations, and navigating to correctly estimate the location of the spacecraft in space are just a few of the vital responsibilities that a space mission brings. In this paper, space navigation, specifically optical spacecraft navigation, is put to the test with the help of many Freeware and Free Open Source Software tools such as Wolfram Mathematica and Jupyter Notebook to see the validity of an optical navigation model. Direct and inverse problems are proposed to calculate and observe whether it is possible to accurately measure the topocentric ecliptic and celestial coordinates of 55 systematically chosen beacon asteroids of known heliocentric Cartesian coordinates. Then, going in reverse, as the inverse problem, computing the heliocentric coordinates to compare with the original known values establishes the model's reliability. By doing so, systematic errors were identified and discussed.
Galvano-rotational effect induced by electroweak interactions in pulsars

description: We study electroweakly interacting particles in rotating matter. The existence of the electric current along the axis of the matter rotation is predicted in this system. This new galvano-rotational effect is caused by the parity violating interaction between massless charged particles in the rotating matter. We start with the exact solution of the Dirac equation for a fermion involved in the electroweak interaction in the rotating frame. This equation includes the noninertial effects. Then, using the obtained solution, we derive the induced electric current which turns out to flow along the rotation axis. We study the possibility of the appearance of the galvano-rotational effect in dense matter of compact astrophysical objects. The particular example of neutron and hypothetical quark stars is discussed. It is shown that, using this effect, one can expect the generation of toroidal magnetic fields comparable with poloidal ones in old millisecond pulsars. We also briefly discuss the generation of the magnetic helicity in these stars. Finally we analyze the possibility to apply the galvano-rotational effect for the description of the asymmetric neutrino emission from a neutron star to explain pulsars kicks.
