Dispositional empathy, dyadic perspective-taking, and interpersonal perceptions among married persons in relation to marital adjustment
Creators: name: Morgenstern, Mark E
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: Several studies have shown that various aspects of empathy are important in relationship satisfaction. In addition, the similarity, assumed similarity, and accuracy of interpersonal perceptions among married couples have also been shown to be positively related to marital adjustment. The present study examined these variables in a sample of 42 married couples. It was found that Perspective-Taking and Empathic Concern, as well as Dyadic Perspective-Taking were positively associated with marital adjustment. In addition, it was observed that accuracy of interpersonal perceptions was positively related to marital satisfaction and satisfaction regarding conflict resolutions. This significant correlation did not remain, however, when the effects of similarity and assumed similarity were taken into account. Finally, it was proposed that Perspective-Taking ability would be positively related to accuracy of interpersonal perceptions. This hypothesis was largely unsupported.

description: We study the effect of lifting the degeneracy of vortex modes with a PT symmetric defect, using discrete vortices in a circular array of nonlinear waveguides as an example. When the defect is introduced, the degenerate linear vortex modes spontaneously break PT symmetry and acquire complex eigenvalues, but nonlinear propagating modes with real propagation constants can still exist. The stability of nonlinear modes depends on both the magnitude and the sign of the vortex charge, thus PT symmetric systems offer new mechanisms to control discrete vortices.

description: This audiovisual essay addresses the poetics of time in cinema through depictions of objects that are markers of certain temporal densities. By exploring three films the essay offers a view to the petrified objects as the symptoms of the filmmaker’s obsessions with time. In the films cited here, time is a matter of concern as a historical process, as construction within the physical laws, and ultimately, as a psychological perception.

description: A co-crystalline adduct consisting of a phosphinine selenide and an organohalide was obtained by slow evaporation of the solvent from a mixture of 2,6-bis(trimethylsilyl)phosphinine selenide and 1,4-diiodotetrafluorobenzene (1,4-TFDIB). The crystallographic characterization of the product shows π-π stacking, F⋅⋅⋅H hydrogen bonding between 1,4-TFDIB and the phosphinine selenide, as well as F⋅⋅⋅F interactions between 1,4-TFDIB molecules. Moreover, the phosphorus heterocycle could be crystallized with diiodine to form a 1 : 1 adduct. The d(I−I) distance in this compound is 2.8475(3) Å, which is shorter than the corresponding one in triphenylphosphine selenide diiodide, reflecting the weaker net-donor power of the phosphinine selenide towards diiodine. The phosphinine selenide could also be used as a selenium transfer reagent to generate KSeCN from KCN.

description: Over time, some instructional strategies may become outdated and fail to meet learners’ needs, and some extraordinary circumstances (e.g., COVID-19 pandemic) necessitate adopting innovative methods in education. Referring to this issue, Borba (2021) revealed that the pandemic changed the agenda of mathematics education, transforming students’ homes into their classrooms. This situation reflects the concept of flipped learning pedagogy (FLP) which combines face-to-face and online learning and encourages students to take an active role in their own learning (Cevikbas & Kaiser, 2021). Mathematics educators (Bakker et al., 2021; Engelbrecht et al., 2020) reported various opportunities of hybrid learning modes, in particular FLP, to “redefine learning spaces, removing barriers between the home and school and making learning more accessible in a multiple of ways” (Attard & Holmes, 2020, p. 18). Although FLP can create numerous benefits for mathematics education, learners and instructors may encounter some important challenges when inverting mathematics instruction, for example, paradigm shift, creating new content, lack of competence and experience in the use of technology, and technological glitches (Cevikbas & Kaiser, 2020).

description: Weak noise smooths out fractals in a chaotic state space and introduces a maximum attainable resolution to its structure. The balance of noise and deterministic stretching/contraction in each neighborhood introduces local invariants of the dynamics that can be used to partition the state space. We study the local discrete-time evolution of a density in a two-dimensional hyperbolic state space, and use the asymptotic eigenfunctions for the noisy dynamics to formulate a new state space partition algorithm.

Adolescents’ neural reactivity to acute psychosocial stress: dysfunctional regulation habits are linked to temporal gyrus response

description: Mid-adolescence is a critical time for the development of stress-related disorders and it is associated with significant social vulnerability. However, little is known about normative neural processes accompanying psychosocial stress at this time. Previous research found that emotion regulation strategies critically influence the relationship between stress and the development of psychiatric symptoms during adolescence. Using functional magnetic resonance imaging (fMRI), we examined neural responses to acute stress and analyzed whether the tendency to use adaptive or maladaptive emotion regulation strategies is related to neural and autonomic stress responses. Results show large linear activation increases from low to medium to high stress levels mainly in medial prefrontal, insulae and temporal areas. Caudate and subgenual anterior cingulate cortex, neural areas related to reward and affective valuations, showed linearly decreasing activation. In line with our hypothesis, the current adolescent neural stress profile resembled social rejection and was characterized by pronounced activation in insula, angular and temporal cortices. Moreover, results point to an intriguing role of the anterior temporal gyrus. Stress-related activity in the anterior temporal gyrus was positively related to maladaptive regulation strategies and stress-induced autonomic activity. Maladaptive coping might increase the social threat and reappraisal load of a stressor, relating to higher stress sensitivity of anterior temporal cortices.

description: Vielfach zitiert ist die Sicht auf Mathematik als Wissenschaft der Muster und Strukturen; mathematisches Tätigsein zeigt sich demnach in der Auseinandersetzung mit Mustern (bspw. Devlin, 1998). Folglich hat die Fähigkeit, Muster und Strukturen zu erkennen, eine zentrale Bedeutung für mathematisches Lernen. Nach Lüken (2012, S. 22) lassen sich die Begriffe Muster und Struktur wie folgt abgrenzen: „Ein Muster […] beschreibt eine Regelmäßigkeit. […] Die Beziehungen zwischen den verschiedenen Bestandteilen eines Musters stellen eine Struktur dar.“ Aufgrund des engen Verhältnisses zwischen den beiden Begriffen wird auch häufig in der Kombination von Muster- und Strukturerkennung gesprochen. Bei der Muster- und Strukturerkennung handelt es sich um einen mentalen Prozess (bspw. Goldstein, 2008), der sich durch eine individuelle, konstruktive Tätigkeit auszeichnet (Lüken, 2012) und komplexe Wahrnehmungstätigkeiten voraussetzt. Dabei lassen sich die Beziehungen zwischen Muster und Struktur nicht konkret abbilden, „sondern [müssen] abstrakt verstanden und in das Muster hineingedeutet werden“ (ebd., S. 23f.). Für den Mathematikunterricht bedeutet dies, dass u.a. „das Erkennen von Beziehungen zwischen Zahlen – also das ‚Sehen‘ mathematischer Strukturen“ (Häsel-Weide, 2013, S. 23) als höchst bedeutsam eingeschätzt werden kann.

description: In der Mathematikdidaktik herrscht weitgehend Konsens, dass inklusiver Mathematikunterricht neben individuellen auch gemeinsame Lernsituationen umfassen sollte (u. a. Häsel-Weide & Nührenbörger, 2021; Korff, 2018; Prediger & Buró, 2021). Die Gestaltung gemeinsamer Lernsituationen stellt damit eine zentrale fachdidaktische Anforderung für (angehende) Lehrkräfte im inklusiven Mathematikunterricht dar (Prediger & Buró, 2021). Verschiedene Studien zeigen bei Lehrkräften ein weites Verständnis von gemeinsamen Lernen, vor allem im Sinne der sozialen Teilhabe. Das gemeinsame fachliche Lernen findet im inklusiven Unterricht nur selten statt und stellt eine besondere Herausforderung für die Lehrkräfte dar (u. a. Korff, 2018; Prediger & Buró, 2021). Grundlegend zur Initiierung gemeinsamer, fachlicher Lernprozesse sind u. a. gemeinsame, substanzielle Aufgaben (Häsel-Weide & Nührenbörger, 2021). Diese erfordern das gleiche Lernangebot für alle Kinder, inhaltliche Ganzheitlichkeit und hinreichende Komplexität, Freiheitsgrade der Lernenden, soziales Lernen von- und miteinander sowie eine niedrige Einstiegsschwelle, Herausforderungen, Diskussionsbedarf und eine kognitive Aktivierung (Krauthausen & Scherer, 2016). Um bereits im Lehramtsstudium ein solches Professionswissen mit konkreten Unterrichtssituationen zu verbinden, haben sich videobasierte Lehrmodule zur Förderung der professionellen Wahrnehmung bewährt (Junker et al., 2020).

description: Die Lehrer*innenbildung ist in Deutschland grundsätzlich dreiphasig organisiert. Für die im Folgenden genauer betrachteten Studiengänge, die für ein Lehramt der Sekundarstufe II (an Gymnasien, Gesamtschulen und Berufskollegs) qualifizieren, besteht die erste Phase aus einem wissenschaftlichen Studium an einer Universität, das fachliche und fachdidaktische Module in mindestens zwei Unterrichtsfächern sowie bildungswissenschaftliche Module umfasst; hinzu kommen sogenannte Praxiselemente, die i. d. R. begleitet im Berufsfeld Schule durchgeführt werden. Die zweite Phase (Referendariat) ist überwiegend schulpraktisch ausgerichtet – in den meisten Bundesländern mit Seminarangeboten, Ausbildungsunterricht und eigenverantwortlichem Unterricht. Als dritte Phase schließt sich die berufsbegleitende Fortund Weiterbildung an. Diese Struktur der Lehrer*innenbildung führt zu einer fortwährenden Diskussion über das Theorie Praxis-Verhältnis und die Relevanz der umfassenden wissenschaftlichen Wissensgrundlage, die im Studium verfügbar gemacht werden soll.

description: We theoretically show that core-excited state populations can be efficiently manipulated with strong optical fields during their decay, which takes place in a few femtoseconds. We focus on the $1s^{-1}3p$ resonant excitation in neon, where the $1s^{-1}3p$ and $1s^{-1}3s$ core-excited states are coupled by an optical field. By analyzing the Auger electron spectrum we observe the inner-shell population transfer induced by the optical coupling. We also show that the angular anisotropy of the Auger electron is imprinted in the multipeak structure induced by the optical-dressed continuum, namely sidebands.

description: Sickle cell disease (SCD) is a lifelong burdensome disorder of heterogenic expression. This study investigated the longer-term economic burden of severe presentation of SCD. As SCD treatment landscapes evolve toward curative intent gene therapies, understanding how SCD-associated costs may change over the patient lifetime will be important for medical decision-making. Patients with severe presentation of SCD (presence of acute vaso-occlusive events [VOEs] or history of stroke and/or other disease-related sequelae), were identified within the MarketScan Commercial and Medicare Supplemental and Multi-state Medicaid Databases from 1/1/2010 to 12/31/2018. The first SCD claim served as the index date and patients were followed over a 5-year post-period. Clinical characteristics and healthcare resource utilization and costs were assessed over follow-up for eligible cohorts of commercial and Medicaid patients with severe SCD presentation and age-based subgroups (<18, 18–30, and ≥31). A total of 4,487 patients, primarily insured via Medicaid (79.2%), qualified for the analysis. Patients evidenced persistent VOEs over follow-up; prevalence of most comorbidities increased with age. Mean total healthcare costs over the 5-year follow-up were $275,143 (SD± $406,770) and $362,728 (SD± $620,189) in the commercial and Medicaid samples, respectively. Disease severity, assessed by the number of VOEs and utilization of inpatient and emergency services, peaked in the 18–30 year group in both samples. These groups also evidenced the highest mean healthcare costs over the 5-year follow-up at $344,776 (SD± $434,521) and $671,321 (SD± $938,764) in the commercial and Medicaid samples respectively. Results indicate high clinical need and economic burden among patients with severe presentation of SCD. These findings not only highlight the need for improved therapeutic options to limit or prevent disease progression, but also start to provide insight on lifetime costs of SCD that will be needed in the evaluation of emerging curative intent therapies.

description: The onset of the asymmetry of planetary nebulae (PNe) is expected to occur during the late Asymptotic Giant Branch (AGB) and early post-AGB phases of low- and intermediate-mass stars. Among all post-AGB objects, the most heavily obscured ones might have escaped the selection criteria of previous studies detecting extreme axysimmetric structures in young PNe. Since the most heavily obscured post-AGB sources can be expected to descend from the most massive PN progenitors, these should exhibit clear asymmetric morphologies. We have obtained VISIR-VLT mid-IR images of four heavily obscured post-AGB objects barely resolved in previous Spitzer IRAC observations to analyze their morphology and physical conditions across the mid-IR. The VISIR-VLT images have been deconvolved, flux calibrated, and used to construct RGB composite pictures as well as color and optical depth maps that allow us to study the morphology and physical properties of the extended emission of these sources. We have detected extended emission from the four objects in our sample and resolved it into several structural components that are greatly enhanced in the temperature and optical depth maps. They reveal the presence of asymmetry in three young PNe (IRAS 15534-5422, IRAS 17009-4154, and IRAS 18454+0001), where the asymmetries can be associated with dusty torii and slightly bipolar outflows. The fourth source (IRAS 18229-1127), a possible post-AGB star, is better described as a rhomboidal detached shell. The heavily obscured sources in our sample do not show extreme axisymmetric morphologies. This is at odds with the expectation of highly asymmetrical morphologies in post-AGB sources descending from massive PN progenitors. The sources presented in this paper may be sampling critical early phases in the evolution of massive PN progenitors, before extreme asymmetries develop.

description: We report on resistivity and Hall measurements performed on a series of narrow mesa devices fabricated from LaAlO_3/SrTiO_3 single interface heterostructure with a bridge width range of 1.5-10 microns. Upon applying back-gate voltage of the order of a few Volts, a strong increase in the sample resistance (up to factor of 35) is observed, suggesting a relatively large capacitance between the Hall-bar and the gate. The high value of this capacitance is due to the device geometry, and can be explained within an electrostatic model using the Thomas Fermi approximation. The Hall coefficient is sometimes a non-monotonic function of the gate voltage. This behavior is inconsistent with a single conduction band model. We show that a theoretical two-band model is consistent with this transport behavior, and indicates a metal to insulator transition in at least one of these bands.

description: The monumental Late Bonze Age royal tomb of Seddin is located in the old morainic landscape of the Prignitz region, northeastern Germany. Together with other richly equipped burials and a row of stone pits in its direct vicinity, it provides evidence for the presence of an elite from the nineth to sixth centuries BCE in this region. Our map emphasizes the well-chosen location of the royal tomb in relation to the spatial arrangement of other archaeological monuments that together form an ensemble of a ritual landscape. We trace legacies of land use from the Bronze Age to the present against the backdrop of Late Quaternary landscape evolution. These include the Bronze Age landscape (re-)organization for ritual and economic purposes, its medieval use for arable farming, its economic use and settlement history in historic times, and modern times melioration of agricultural areas that together form the palimpsest of the present-day landscape.

description: In response to ESA’s “Voyage 2050” announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn’s largest moon Titan. Titan, a “world with two oceans”, is an organic-rich body with interior-surface-atmosphere interactions that are comparable in complexity to the Earth. Titan is also one of the few places in the Solar System with habitability potential. Titan’s remarkable nature was only partly revealed by the Cassini-Huygens mission and still holds mysteries requiring a complete exploration using a variety of vehicles and instruments. The proposed mission concept POSEIDON (Titan POlar Scout/orbitEr and In situ lake lander DrONe explorer) would perform joint orbital and in situ investigations of Titan. It is designed to build on and exceed the scope and scientific/technological accomplishments of Cassini-Huygens, exploring Titan in ways that were not previously possible, in particular through full close-up and in situ coverage over long periods of time. In the proposed mission architecture, POSEIDON consists of two major elements: a spacecraft with a large set of instruments that would orbit Titan, preferably in a low-eccentricity polar orbit, and a suite of in situ investigation components, i.e. a lake lander, a “heavy” drone (possibly amphibious) and/or a fleet of mini-drones, dedicated to the exploration of the polar regions. The ideal arrival time at Titan would be slightly before the next northern Spring equinox (2039), as equinoxes are the most active periods to monitor still largely unknown atmospheric and surface seasonal changes. The exploration of Titan’s northern latitudes with an orbiter and in situ element(s) would be highly complementary in terms of timing (with possible mission timing overlap), locations, and science goals with the upcoming NASA New Frontiers Dragonfly mission that will provide in situ exploration of Titan’s equatorial regions, in the mid-2030s.

description: In this paper we present the physical design of the pulsed sextupole injection system for Beijing Advanced Photon Source (BAPS) with an ultralow emittance. The BAPS ring lattice is designed in such a way that two options of pulsed sextupole injection are allowed, i.e., with septum and pulsed sextupole in different drift spaces or in the same drift space. We give the magnetic parameters of the injection system and the optimal condition of the optical functions for both options. In addition, we find that the pulsed sextupole induces position-dependent dispersive effect and causes non-ignorable effect on the injection efficiency in a storage ring with a relatively small acceptance, which should be well considered.

Multicasting in generalized class networks
Creators: name: Lane, Carl Michael
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: A problem that we are experiencing in communication networks is the ability to efficiently multicast information to a group of network sites. Multicasting is defined as point to multipoint communications. Within a network, for example, we may want to send a message from one network site to five other network sites. This is an example of a multicasting operation; We are seeing an increased use of applications which blend not only data, but also voice, and video. Due to this increase in usage, we are experiencing a need to conserve network bandwidth and to avoid loading communication networks excessively. To do this, a method must be used to transport the necessary information to its destination sites in an efficient manner; This is where our research comes in. By incorporating multicasting techniques within message transmissions in networks, we can drastically reduce the necessary bandwidth and resource overhead associated with moving messages throughout the network.

The long journey: From institutionalization to adult day care
Creators: name: Kampschroeder, Kristin L
Publisher: name: University of Nevada, Las Vegas
Year: 1996

description: This thesis will present a field study of an adult day care center in an attempt to establish a new methodology which will address the different types of clients in the recent phenomenon of adult day care settings. Previous research and field study has only focused on adults within institutional settings or on the institutions themselves. Adult day care, on the other hand, has arisen as an alternate form of care which allows for greater flexibility and concern for clients' needs. This thesis, then, in differentiating adult day care from total institutions and in delineating the types of clients, will set the groundwork for a new theory which would address the evolving needs of the fragmented adult day care population.

description: Phase coherence of charge carriers leads to electron-wave interference in ballistic mesoscopic conductors. In graphene, such Fabry-Pérot-like interference has been observed, but a detailed analysis has been complicated by the two-dimensional nature of conduction, which allows for complex interference patterns. In this work, we have achieved high-quality Fabry-Pérot interference in a suspended graphene device, both in conductance and in shot noise, and analyzed their structure using Fourier transform techniques. The Fourier analysis reveals two sets of overlapping, coexisting interferences, with the ratios of the diamonds being equal to the width to length ratio of the device. We attribute these sets to a unique coexistence of longitudinal and transverse resonances, with the longitudinal resonances originating from the bunching of modes with low transverse momentum. Furthermore, our results give insight into the renormalization of the Fermi velocity in suspended graphene samples, caused by unscreened many-body interactions.

description: The 2013 Planetary Science Decadal Survey identified a detailed investigation of the Trojan asteroids occupying Jupiter's L4 and L5 Lagrange points as a priority for future NASA missions. Observing these asteroids and measuring their physical characteristics and composition would aid in identification of their source and provide answers about their likely impact history and evolution, thus yielding information about the makeup and dynamics of the early Solar System. We present a conceptual design for a mission to the Jovian Trojan asteroids: the Trojan ASteroid Tour, Exploration, and Rendezvous (TASTER) mission, that is consistent with the NASA New Frontiers candidate mission recommended by the Decadal Survey and the final result of the 2011 NASA-JPL Planetary Science Summer School. Our proposed mission includes visits to two Trojans in the L4 population: a 500 km altitude fly-by of 1999 XS143, followed by a rendezvous with and detailed observations of 911 Agamemnon at orbital altitudes of 1000 - 100 km over a 12 month nominal science data capture period. Our proposed instrument payload - wide- and narrow-angle cameras, a visual and infrared mapping spectrometer, and a neutron/gamma ray spectrometer - would provide unprecedented high-resolution, regional-to-global datasets for the target bodies, yielding fundamental information about the early history and evolution of the Solar System. Although our mission design was completed as part of an academic exercise, this study serves as a useful starting point for future Trojan mission design studies. In particular, we identify and discuss key issues that can make large differences in the complex trade-offs required when designing a mission to the Trojan asteroids.

description: Template for the Swedish national survey questionnaire on internet regulation in public libraries. The survey comprises questions on library demographics, extent and types of content filters and other internet regulation measures; extent and form of Wi-Fi services in the libraries; questions about experiences of misuse, attitues for and against filters; who is responsible for internet regulation decisions and management; library and municipality knowledge, interests, and influence on internet regulation. It also contains questions about personal data collection and management; third party personal data access policies; and user information about filters, data collection and third party access to personal identifiable information. The survey was produced for the national Swedish research project "Internet in public libraries - policy, practice, and pedagogy", and conducted in 2019-2020. The survey is designed for anonymous participation and digital distribution, but can be adapted to non-anonymised data collection and paper based/manual and/or oral survey/interview formats.
Tunneling phenomenon in heterostructure devices
Creators: name: Maheshwarla, Sreenivasulu V

description: A theoretical formulation for carrier current across hetero-interface in heterostructure semiconductor devices is presented using tunneling as the phenomenon. An analytical expression for the transmission coefficient as a function of energy using the Airy's function and exponential solutions to Schroedinger's equation for a linear potential variation is used in the calculations. This thesis addresses two theoretical problems: physics and modeling of gate current dependance on gate voltage in a heterostructure insulated gated field effect transistor (HIGFET) and, oscillations in the current-voltage characteristics of a double heterostructure bipolar transistor (DHBT); For HIGFETs, two components of tunneling currents, one from the decay of the quasi-bound resonant states in the accumulation well and the other from the tunneling electrons with kinetic energy above the bulk energy level, were considered. Moreover, the possibility of hot electrons is addressed. The reason for the large discrepancies between the experimental values and the theoretical values reported in earlier literature is attributed mainly due to the exclusion of the hot electron mechanism and the neglect of the contribution to current from the decay of the resonant states in the accumulation well; The origin of oscillations in the collector saturation current of a DHBT (with a set back layer) is investigated theoretically. Energy band balance was performed at the base-set back layer and set back layer-collector junctions to determine the distribution of the output voltage, {dollar}V\sb{BC}{dollar}, at these junctions and the conduction band edge profile using degenerate statistics. Theoretical results are in excellent agreement with the experimental results with {dollar}V\sb{BC}{dollar}'s at which the first two peaks of the {dollar}I\sb{D,sat}{dollar} occur matching closely.

A study of training methodology for customer contact employees in Spain, and implications on service quality

description: Studies on training for customer contact employees in the hotel industry have not been found in Spain. In the United States, ample research has been conducted in the areas of training, service quality, and customer satisfaction. However, studies on training programs for customer contact employees, and studies that address the influence of customer contact employees on customers' perceptions of quality are fairly This exploratory study was intended to evaluate the training methodology provided to customer contact employees in luxury properties in Spain, to assess perceptions of effectiveness of such training methods, and to relate such methodology to perceptions of service quality. It was found that a property's commitment to customer service might be related to the ratio of customer contact employees to total number of employees, that importance given to training might differ according to hotel ownership, and that most training is conducted on-the-job.

description: A storage ring-based light source, Beijing Advanced Photon Source (BAPS) is proposed to store 5-GeV low-emittance electron beam and to provide high-brilliance coherent radiation. In this paper, we report our efforts of pushing down the emittance of BAPS to approach the so-called ultimate storage ring, while fixing the circumference to about 1200 m. To help dealing with the challenge of beam dynamics associated with the intrinsic very strong nonlinearities in an ultralow-emittance ring, a combination of several progressive technologies is used in the linear optics design and nonlinear optimization, such as modified theoretical minimum emittance cell with small-aperture magnets, quasi-3rd-order achromat, theoretical analyzer based on Lie Algebra and Hamiltonian analysis, multi-objective genetic algorithm, and frequency map analysis. These technologies enable us to obtain satisfactory beam dynamics in one lattice design with natural emittance of 75 pm.
Reservoir model for two-dimensional electron gases in quantizing magnetic fields: a review

description: We collect and review works which treat two-dimensional electron gases in quantum wells (mostly GaAs/GaAlAs heterostructures) in the presence of quantizing magnetic fields as open systems in contact with outside reservoirs. If a reservoir is sufficiently large, it pins the Fermi level to a certain energy. As a result, in a varying external magnetic field, the thermodynamic equilibrium will force oscillations of the electron density in and out of the quantum well (QW). This leads to a number of physical phenomena in magneto-transport, interband and intraband magneto-optics, magnetization, magneto-plasma dispersion, etc. In particular, as first proposed by Baraff and Tsui, the density oscillations in and out of QW lead to plateaus in the Integer Quantum Hall Effect (IQHE) at values observed in experiments. The gathered evidence, especially from magneto-optical investigations, allows us to conclude that, indeed, in most GaAs/GaAlAs hetrostructures one deals with open systems in which the electron density in QWs oscillates as the magnetic field varies. Relation of the density oscillations to other factors, such as electron localization, and their combined influence on the quantum transport in 2D electron gases, is discussed. In particular, a validity of the classical formula for the Hall resistivity ρxy = B/Nec is considered. It is concluded that the density oscillations are not sufficient to be regarded as the only source of plateaus in IQHE, although such claims have been sometimes made in the past and present. Still, our general conclusion is that the reservoir approach should be included in various descriptions of 2D electron gases in the present of a magnetic field. An attempt has been made to quote all the relevant literature on the subject.

description: Improvements in stage isentropic efficiency and reductions in total pressure loss are sought in a 1.5 stage axial turbine. This is representative of power generation equipment used in thermal power cycles, which deliver about 80% of the 20 trillion kWh world-wide electricity. Component-level improvements are therefore timely and important towards achieving carbon dioxide global emission targets. Secondary flow loss reduction is sought by applying a non-axisymmetric endwall design to the turbine stator hub. A guide groove directs the pressure side branch of the horseshoe vortex away from the airfoil suction side, using a parametric endwall hub surface, which is defined as to obtain first-order smooth boundary connections to the remainder of the passage geometry. This delays the onset of the passage vortex and reduces its associated loss. The Automatic Process and Optimization Workbench (APOW) generates a Kriging surrogate model from a set of Reynolds Averaged Navier-Stokes (RANS) simulations, which is used to optimize the hub surface. The three-dimensional steady RANS model with an axisymmetric hub is validated against reference experimental measurements from Rheinisch-Westfälische Technische Hochschule Aachen. Comparative computational fluid dynamics predictions with an optimized non-axisymmetric hub show a decrease in the total pressure loss coefficient and an increase in the isentropic stage efficiency at and off design conditions.
