description: The dust in nearby galaxies absorbs a fraction of the UV-optical-near-infrared radiation produced by stars. This energy is consequently re-emitted in the infrared. We investigate the portion of the stellar radiation absorbed by spiral galaxies from the HRS by modelling their UV-to-submillimetre spectral energy distributions. Our models provide an attenuated and intrinsic SED from which we find that on average 32 % of all starlight is absorbed by dust. We define the UV heating fraction as the percentage of dust luminosity that comes from absorbed UV photons and find that this is 56 %, on average. This percentage varies with morphological type, with later types having significantly higher UV heating fractions. We find a strong correlation between the UV heating fraction and specific star formation rate and provide a power-law fit. Our models allow us to revisit the IRX-AFUV relations, and derive these quantities directly within a self-consistent framework. We calibrate this relation for different bins of NUV-r colour and provide simple relations to relate these parameters. We investigated the robustness of our method and we conclude that the derived parameters are reliable within the uncertainties which are inherent to the adopted SED model. This calls for a deeper investigation on how well extinction and attenuation can be determined through panchromatic SED modelling.

description: Die Digitalisierung hat das Bauwesen signifikant verändert. Building Information Modeling (BIM) verspricht dabei, die Effizienz und Qualität der Planungs- und Bauprozesse zu steigern. Im Bereich des Brandschutzes bleibt die Nutzung von BIM jedoch begrenzt, wobei viele Informationsaustauschprozesse weiterhin über 2D CAD oder in Papierform erfolgen. Diese Masterarbeit untersucht die Integration von Brandschutzinformationen in BIM-Modelle, um deren Nutzung sowohl im Planungsprozess als auch in der Nutzungsphase durch Feuerwehren zu verbessern. Die zentralen Forschungsfragen adressieren die Ansprüche der verschiedenen Stakeholder und den Mehrwert, den BIM für diese bietet. Die Methodik umfasst eine systematische Literaturrecherche, Expertengespräche mit verschiedenen Stakeholdern und die Entwicklung sowie Validierung eines praxisorientierten Lösungsansatzes durch eine Fallstudie. Die Ergebnisse der Fallstudie werden durch erneute Expertengespräche validiert. Die Ergebnisse zeigen, dass die Integration von Brandschutzanforderungen in BIM-Modelle die Datenkonsistenz und Qualitätssicherung erheblich verbessert. Zudem ermöglichen die entwickelten Lösungen eine effizientere Kommunikation zwischen den Beteiligten. Ein praxisorientierter Leitfaden bietet detaillierte Schritte zur Implementierung und Überprüfung von Brandschutzinformationen in BIM-Modelle. In der Diskussion wird betont, dass die Akzeptanz und der Erfolg von BIM im Brandschutz massgeblich von der Bereitschaft der Stakeholder abhängen, bestehende Prozesse zu überdenken und neue Technologien zu integrieren. Hierzu sind Schulungen und kontinuierliche Weiterbildung unerlässlich. Empfohlen wird, die Nutzung von BIM im Brandschutz kontinuierlich zu fördern, die bestehenden Prozesse anzupassen und die Interoperabilität zwischen verschiedenen Softwareanwendungen weiter zu verbessern, um die Digitalisierung in diesem Bereich nachhaltig voranzutreiben.

description: As one of the leading causes of death in the United States, cancer impacts the lives of Democrats, Republicans and Independents alike. Correspondingly, we might expect potential preventative cancer therapies to be more-or-less “immune” to partisan polarization. Experiences with the deadly COVID-19 pandemic, however, suggest that even amid an unprecedented public health threat, Americans were nevertheless motivated by political partisanship (particularly on the right) to reject life-saving preventatives. In this study, I investigate whether tying the accomplishments of high-profile partisans to the vaccine approval process might influence public acceptance of “personalized cancer vaccines,” which prevent the onset of cancer using tumor detection and mitigation mechanisms informed by one’s DNA. In a pre-registered survey experiment, I expect to find that -- while Republicans should be more likely to hold negative views toward cancer vaccination in the absence of partisan cues -- linking the vaccine to Democratic elites will further polarize public opinion. I also expect that linking the vaccine to Republican elites may depolarize attitudes by either decreasing Democrats’ vaccine acceptance and/or by improving Republican acceptance. I conclude by discussing how these findings can motivate effective political and health communication about cancer vaccination.

Under the magnetic field created by magnets beside the glass slide, north-seeking MTB could swim to the left edge of the water droplet from the sediment. Then the individual potential LHC-1 cells were selected and picked up using a single capillary needle and washed four times in the four drops of liquid on the glass slide. The cells were washed two times with filtered sample water, and two times with sterilized PBS buffer. Finally, different numbered cell groups were collected for single-cell sequencing.

description: In the United States, Asian Americans are often stereotyped as Model Minorities (i.e., high-achieving, and well-off racial minorities). However, such positive stereotypes can have negative consequences (i.e., feeling depersonalized, negative emotions, poor mental health, cognitive deficits, and somatic symptoms). In addition, these positive stereotypes could cause people to not think Asian Americans do not experience racial prejudice/discrimination. Therefore, we aim to study how the Model Minority myth exacerbates the invisibility of anti-Asian racism or “raises the threshold” for detecting anti-Asian racism.

description: Recent advances in Unmanned Aerial Vehicles (UAVs) have resulted in their quick adoption for wide a range of civilian applications, including precision agriculture, biosecurity, disaster monitoring and surveillance. UAVs offer low-cost platforms with flexible hardware configurations, as well as an increasing number of autonomous capabilities, including take-off, landing, object tracking and obstacle avoidance. However, little attention has been paid to how UAVs deal with object detection uncertainties caused by false readings from vision-based detectors, data noise, vibrations, and occlusion. In most situations, the relevance and understanding of these detections are delegated to human operators, as many UAVs have limited cognition power to interact autonomously with the environment. This paper presents a framework for autonomous navigation under uncertainty in outdoor scenarios for small UAVs using a probabilistic-based motion planner. The framework is evaluated with real flight tests using a sub 2 kg quadrotor UAV and illustrated in victim finding Search and Rescue (SAR) case study in a forest/bushland. The navigation problem is modelled using a Partially Observable Markov Decision Process (POMDP), and solved in real time onboard the small UAV using Augmented Belief Trees (ABT) and the TAPIR toolkit. Results from experiments using colour and thermal imagery show that the proposed motion planner provides accurate victim localisation coordinates, as the UAV has the flexibility to interact with the environment and obtain clearer visualisations of any potential victims compared to the baseline motion planner. Incorporating this system allows optimised UAV surveillance operations by diminishing false positive readings from vision-based object detectors.
Earnings in North Carolina: An Analysis of the Industrial Mix and Local Effects

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1975

description: The impressive growth of economic activity in the State of North Carolina since World War II has been accompanied by a rather disappointing performance in per capita personal income. It now seems apparent that the rapid rate of closure between North Carolina and the rest of the United States in per capita personal income has declined in recent years. Further, economic projections indicate that North Carolina will likely continue to experience little growth in per capita income relative to the nation. Per capita personal income is perhaps the most widely accepted and applied social indicator of the quality of life in a region. While per capita income is primarily an economic indicator, both economic and non-economic variables may affect its level. For example, high dependency ratios reflect a relatively lower percentage of the population in working ages and tend to depress per capita income. The labor force participation rate and the unemployment rate account for that part of the working age population actually employed. Together these factors determine the proportion of society employed in the economy. Earnings received in exchange for labor service account annually for more than four-fifths of total personal income in North Carolina, the remainder being composed of proprietors' income, property income, and transfer payments.

description: We study the quark hadron phase transition in the framework of massive gravity. We show that the modification of the FRW cosmological equations leads to the quark hadron phase transition in the early massive Universe. Using numerical analysis, we consider that a phase transition based on the chiral symmetry breaking after the electroweak transition, occurred at approximately $10 μ$ seconds after the Big Bang to convert a plasma of free quarks and gluons into hadrons.

With the help of these deformed "bosonic" numbers, the corresponding skein relations can be reproduced. Analyzing the introduced "bosonic" numbers, we point out two ways of obtaining the two-parameter HOMFLY skein relation ("bosonic" (q,p)-numbers) from the one-parameter Alexander and Jones skein relations (from the corresponding "bosonic" q-numbers). These two ways of obtaining the HOMFLY skein relation are equivalent.

description: We report on several new results using anisotropies of UHECRs. We improve and extend the work of Ding, Globus and Farrar, who modeled the UHECR dipole assuming sources follow the dark matter distribution, accounting for deflections in the Galactic and extragalactic magnetic fields but using a simplified treatment of interactions during propagation. The work presented here employs an accurate and self-consistent treatment of the evolution of composition during propagation, allows for and explores the impact of "bias" in the relation between UHECR sources and the dark matter distribution, and investigates the possible generation of arrival-direction-dependent composition anisotropies. Limits on the source number density consistent with the observed anisotropies are derived for the case where UHECR sources follow the dark matter distribution, and compared to a homogeneous source distribution case.

description: Asteroids that could collide with the Earth are listed on the publicly available Near-Earth object (NEO) hazard web sites maintained by the US and European space agencies (NASA and ESA). The impact probability distribution of 69 potentially threatening NEOs from these lists that produce 261 dynamically distinct impact instances, or Virtual Impactors (VIs), were calculated using the Asteroid Risk Mitigation and Optimization Research (ARMOR) tool in conjunction with OrbFit. ARMOR projected the impact probability of each VI onto the surface of the Earth as a spatial probability distribution. The projection considers orbit solution accuracy and the global impact probability. The method of ARMOR is introduced and the tool is validated against two asteroid-Earth collision cases with objects 2008 TC3 and 2014 AA. In the analysis, the natural distribution of impact corridors is contrasted against the impact probability distribution to evaluate the distributions conformity with the uniform impact distribution assumption. The distribution of impact corridors is based on the NEO population and orbital mechanics. The analysis shows that the distribution of impact corridors matches the common assumption of uniform impact distribution and the result extends the evidence base for the uniform assumption from qualitative analysis of historic impact events into the future in a quantitative way. This finding is confirmed in a parallel analysis of impact points belonging to a synthetic population of 10006 VIs. Taking into account the impact probabilities introduced significant variation into the results and the impact probability distribution, consequently, deviates markedly from uniformity. The concept of impact probabilities is a product of the asteroid observation and orbit determination technique and, thus, represents a man-made component that is largely disconnected from natural processes.

description: How to not only arrest the decline of cities constituting the American Rust Belt, but also reposition these former prosperous metropolises for future success is one of the most vexing and significant issues facing urban design and planning professionals. Brent Ryan’s work, Design after Decline: How America Rebuilds Shrinking Cities, is an excellent addition to this incredibly relevant and growing literature. Using two case studies – Philadelphia and Detroit – Ryan details the precipitous decline of two of America’s former industrial giants and their attempts to halt what amounts to an inescapable spiral of population loss, crumbling infrastructure, and economic hardship.

description: We discuss mixed inflaton and spectator field models where both the fields are responsible for the observed density fluctuations. We use the current CMB data to constrain both the general mixed model as well as some specific representative scenarios, and collate the results with the model predictions for the CMB spectral $μ$ distortion. We find the posterior distribution of $μ$ using MCMC chains and demonstrate that the standard single-field inflaton model typically predicts $μ\sim 10^{-8}$ with a relatively narrow distribution, whereas for the mixed models, the distribution turns out to be much broader, and $μ$ could be larger by almost an order of magnitude. Hence future experiments of $μ$ distortion could provide a tool for the critical testing of the mixed source models of the primordial perturbation.

Analysis of Bogota's Bus Rapid Transit System and its Impact on Land Development

description: Recent experiences in Latin American cities supporting world-class public transportation systems have resulted in the creation of livable spaces with a significant potential to spur land development. In cities like Bogota, Colombia, and Curitiba. Brazil, bus rapid transit (BRT) has re-emerged as a cost-effective transportation alternative for satisfying growing demands for urban mobility. Bogota's BRT system has allowed for a 32 percent reduction in average travel times and significant reduction in accident and air pollution levels along the busway corridors. Although previous research suggests that the impacts of access to BRT facilities on the nearby land value and use have been minor, new BRT systems like the one in Bogota feature intensive infrastructure facilities and their effects in terms of accessibility and mobility have been impressive. This paper provides first-hand empirical evidence on the evaluation of how the BRT system is related to land development outcomes such as land values. Future BRT extensions will have a large potential to influence future land development and induce desirable urban forms and land uses around stations and busway corridors.

description: The LHCb experiment is one of the four large detectors operating at the LHC at CERN and it is mainly devoted to CP violation measurements and to the search for new physics in rare decays of beauty and charm hadrons. The data from the two Ring Image Cherenkov (RICH-1 and RICH-2) detectors are essential to identify particles in a wide momentum range. From 2019 onwards 14 TeV collisions with luminosities reaching up to $2\cdot10^{33}$ cm$^{-2}$ s$^{-1}$ with 25 ns bunch spacing are planned, with the goal of collecting 5 fb$^{-1}$ of data per year. In order to avoid degradation of the PID performance at such high rate (40 MHz), the RICH detector has to be upgraded. New photodetectors (Multi-anode photomultiplier tubes, MaPMTs) have been chosen and will be read out using a 8-channels chip, named CLARO, designed to sustain a photon counting rate up to 40 MHz, while minimizing the power consumption and the cross-talk. A 128-bit digital register allows selection of thresholds and attenuation values and provides features useful for testing and debugging. Photosensors and electronics are arranged in basic units, the first prototypes of which have been tested in charged particle beams in autumn 2014. An overview of the CLARO features and of the readout electronics is presented.

description: The possibility that metals may support ferroelectricity is an open issue. Anderson and Blount showed that certain martensitic transitions involve inversion symmetry breaking and the formal existence of a polar axis, so 'metallic ferroelectric' behavior has been claimed for metals undergoing a centrosymmetric (CS) to non-CS structural transformation (Cd2ReO7, LiOsO3) or natively non-CS (SrCaRu2O), or for ferroelectric insulators whose polar distortion survives moderate metallicity induced by doping or proximity. However, none of these systems, nor any other to our knowledge, embodies a truly ferroelectric metal with native switchable polarization and native metallicity coexisting in a single phase. Here we report the first-ever theoretical prediction of such a material. By first-principles calculations, we show that the layered perovskite Bi5Ti5O17 has a non-zero density of states at the Fermi level and metal-like conductivity, as well as a spontaneous polarization in zero field. Further, we predict that the polarization of Bi5Ti5O17 is switchable both in principle, as the material complies with the sufficient symmetry requirements, and in practice, as Bi5Ti5O17 can sustain a sizable potential drop along the polar direction, as needed to revert its polarization by application of an electric bias.

Entropy-driven formation of prolate and oblate cholesteric phases by computer simulations

description: Predicting the macroscopic chiral behaviour of cholesteric liquid crystals from the microscopic chirality of the particles is highly non-trivial, even when the chiral interactions are purely entropic in nature. Here we introduce a novel chiral hard-particle model, namely particles with a twisted polyhedral shape and obtain, for the first time, a stable fully-entropy-driven cholesteric phase by computer simulations. By slightly modifying the triangular base of the particle, we are able to switch from a left-handed prolate to a right-handed oblate cholesteric using the same right-handed twisted particle model. Furthermore, we find qualitative agreement with an Onsager-like theory, suggesting that the latter can be used as a quick tool to scan the huge parameter space associated to the microscopic chirality. Our results unveil how the competition between particle biaxiality and chirality is reflected into the nematic self-organization and new theoretical challenges on the self-assembly of chiral particles can be undertaken.
Diffractive Processes at Next-to-Leading Order in the Dipole Picture

description: In this thesis, we calculate diffractive processes at next-to-leading order (NLO) in the high-energy limit, with an emphasis on exclusive vector meson production and inclusive diffraction in deep inelastic scattering (DIS). Calculations in the high-energy limit can be done using the dipole picture, the basics of which are briefly reviewed. This includes using the color-glass condensate effective field theory to describe the nonperturbative dipole-target scattering amplitude which appears in practically all calculations in the dipole picture. The universality of the dipole-target scattering amplitude at NLO is shown numerically, in the sense that the same dipole-target scattering amplitude can be used to describe the data in both massless and massive quark production in inclusive DIS, and also in diffractive processes where exclusive vector meson production is considered. The analytical NLO calculations of exclusive vector meson production and inclusive diffraction in DIS are also explained. Exclusive vector meson production is calculated in the nonrelativistic limit for heavy mesons and the limit of large photon virtuality for light mesons. Also, the importance of including relativistic corrections to the heavy vector meson wave function in exclusive vector meson production is considered. For inclusive diffraction in DIS, we focus on the NLO corrections to the final state and show how the divergences cancel.

We perform our investigation within a microscopic transport model based on the Landau-Vlasov kinetic equation. We observe that the peak energies of PDR and IVGDR are shifted to higher values when employing momentum dependent interactions, with respect to the results obtained neglecting momentum dependence. The calculated energies are close to the experimental values and similar to the results obtained in Hartree-Fock (HF) with Random Phase Approximation (RPA) calculations.

description: In late 1989, members of the American Society ofReal Estate Counselors participated in a survey about the major forces that will influence real estate over the next two decades. The respondees agreed overwhelmingly that the economic environment of the United States would determine the vitality of the real estate market. Despite a soft economy, there was substantial optimism. Nearly half felt that interest rates would stabilize at about 9 percent over the next 10-20 years. Of the remainder, however, almost twice as many expected interest rates to increase as expected them to fall. The more optimistic expectations were based on a belief, shared by nearly two-thirds of the experts, that the United States would become more competitive in world markets during the next twenty years, resulting in an improvement in the U.S. balance of trade.

description: In early 2020, an international team of investigators, led by the Montreal Behavioural Medicine Centre (MBMC), launched a large survey-based project (the iCARE Study) aiming to track people’s experiences and behaviours during the COVID-19 pandemic across the world. As part of this endeavor, several sampling strategies were employed to recruit participants, but could be classified into two large categories. The first category regroups efforts (e.g., online advertising, snowball sampling through word-of-mouth) that recruits a convenience-based sample of unpaid volunteers to take the survey. The second category involves efforts to recruit more representative samples for given countries (e.g., using a polling firm that makes use of a large panel selected to match the wider population on key demographic characteristics). The current project aims to examine the degree to which samples produced by these two types of methods produce effects that are comparable/different from each other using Canadian data from the iCARE Study. A detailed preregistration file has been uploaded with this registration. This file outlines our hypotheses, data, and analytic plans.

description: We present the analysis of the state of the global natural resource base through the lens of the planetary health while designing the alliance of life sciences, legal and political studies, and the big data science. We set up priorities in both resource science and governance and suggest instruments and steps in closing the resource-health policy gap. This is a timely and unavoidable endeavor in the current context topped by the combined synergic 2008 and 2020 pandemics crises.

description: Absorption of high-energy radiation in planetary thermospheres is believed to lead to the formation of planetary winds. The resulting mass-loss rates can affect the evolution, particularly of small gas planets. We present 1D, spherically symmetric hydrodynamic simulations of the escaping atmospheres of 18 hot gas planets in the solar neighborhood. Our sample only includes strongly irradiated planets, whose expanded atmospheres may be detectable via transit spectroscopy. The simulations were performed with the PLUTO-CLOUDY interface, which couples a detailed photoionization and plasma simulation code with a general MHD code. We study the thermospheric escape and derive improved estimates for the planetary mass-loss rates. Our simulations reproduce the temperature-pressure profile measured via sodium D absorption in HD 189733 b, but show unexplained differences in the case of HD 209458 b. In contrast to general assumptions, we find that the gravitationally more tightly bound thermospheres of massive and compact planets, such as HAT-P-2 b are hydrodynamically stable. Compact planets dispose of the radiative energy input through hydrogen Ly$α$ and free-free emission. Radiative cooling is also important in HD 189733 b, but it decreases toward smaller planets like GJ 436 b. The simulations show that the strong and cool winds of smaller planets mainly cause strong Ly$α$ absorption but little emission. Compact and massive planets with hot, stable thermospheres cause small absorption signals but are strong Ly$α$ emitters, possibly detectable with the current instrumentation. The absorption and emission signals provide a possible distinction between these two classes of thermospheres in hot gas planets. According to our results, WASP-80 and GJ 3470 are currently the most promising targets for observational follow-up aimed at detecting atmospheric Ly$α$ absorption signals.

description: Analyzed from an international perspective, the distribution of industrial activities has been greatly affected in the past twenty years by the growth of major corporations, most of them American-based multinationals. These giant firms, often able to impose their will upon newly independent nation states or backward regions of industrialized countries, have transformed the geography of industrial location in their constant search for cheap labor, new markets, and favorable "business climates."
Interconnection of defect entropies and enthalpies in BaF$_2$ revisited

description: Here, we investigate the following key prediction of a thermodynamical model that interrelates the defect parameters with the bulk elastic and expansivity data: for various defect processes in a given matrix material, a proportionality exists between defect entropies and enthalpies. The investigation is focused on BaF2 for which ab-initio calculations within density functional theory and the generalized-gradient approximation have been recently made as far as the formation and migration of intrinsic defects is concerned, as well as for the elastic constants. Four defect processes have been studied in BaF$_2$: Anion Frenkel formation, fluorine vacancy migration, fluorine interstitial motion and electrical relaxation associated with a single tetravalent uranium. For these processes, the entropies and enthalpies vary by almost two orders of magnitude and reveal a proportionality between them. We find that this proportionality is solely governed by the bulk elasticity and expansivity data, which conforms to the aforementioned thermodynamical model.

Perception of English Consonant Clusters by Ethiopian EFL Learners Speaking Amharic as First Language
Creators: name: Anegagregn Gashaw
Publisher: name: Abyssinia Journal of Business and Social Sciences
Year: 2016

description: The study examined the perception of Amharic speaking Ethiopian learners of English while they listen to English words with consonant cluster. Five English as a Foreign Language (EFL) learners speaking Amharic as first language participated in the study by completing a forced dictation task in which audio recorded speeches of target words by English native speakers were presented for transcription. Both quantitative and qualitative methods of data analysis were employed before findings were drawn. The result showed that most of the transcriptions the learners provided in response to the stimuli they heard were found to be semantically different with the original ones. The study verified that the learners experience perception problems of consonant clusters of all kinds at all positions both at word and phrase levels. The problem however is more acute when the clusters are composed of those sounds like interdental fricatives which are lacking in the learners mother tongue. On the other hand, three and above consonant clusters particularly when presented across words in connected speeches are found to be critical for the learners to correctly perceive and therefore to comprehend. Based on the findings, recommendations are forwarded to make learners familiar to English consonant clusters so that learners will improve comprehension abilities.

description: Rare long distance dispersal events are thought to have a disproportionate impact on the spread of invasive species. Modelling using integrodifference equations suggests that, when long distance contacts are represented by a fat-tailed dispersal kernel, an accelerating wave of advance can ensue. Invasions spreading in this manner could have particularly dramatic effects. Recently, various authors have suggested that demographic stochasticity disrupts wave acceleration. Integrodifference models have been widely used in movement ecology, and as such a clearer understanding of stochastic effects is needed. Here, we present a stochastic non-linear one-dimensional lattice model in which demographic stochasticity and the dispersal regime can be systematically varied. Extensive simulations show that stochasticity has a profound effect on model behaviour, and usually breaks acceleration for fat-tailed kernels. Exceptions are seen for some power law kernels, $K(l) \propto |l|^{-β}$ with $β< 3$, for which acceleration persists despite stochasticity. Such kernels lack a second moment and are important in `accelerating' phenomena such as Lévy flights. Furthermore, for long-range kernels the approach to the continuum limit behaviour as stochasticity is reduced is generally slow. Given that real-world populations are finite, stochastic models may give better predictive power when long-range dispersal is important. Insights from mean-field models such as integrodifference equations should be applied with caution in such circumstances.
