description: We present a Monte Carlo study of the bond and site directed (oriented) percolation models in $(d+1)$ dimensions on simple-cubic and body-centered-cubic lattices, with $2 \leq d \leq 7$. A dimensionless ratio is defined, and an analysis of its finite-size scaling produces improved estimates of percolation thresholds. We also report improved estimates for the standard critical exponents. In addition, we study the probability distributions of the number of wet sites and radius of gyration, for $1 \leq d \leq 7$.

ON DEMAND: Course Coordination: Balancing Instructor Autonomy & Content Standardization Across Multiple Sections
Creators: name: Ngac, Brian
Publisher: name: Innovations in Teaching & Learning Conference Proceedings
Year: 2021

description: Being a course coordinator comes with many responsibilities including ensuring content consistency, defining learning objectives, establishing competency benchmarks, assuring instructor leeway, and preparing for seamless continuity during instructor absences / disasters across all sections. Ensuring content consistency is important so that any student taking the course will receive at a minimum the baseline knowledge. To ensure content consistency, we'll look at the Master Syllabus and the Baseline Lecture Content. Defining learning objectives and establishing competency benchmarks are also important so that students passing through the course are measured consistently, similarly, and fairly - across different sections. To ensure this, we'll look at common assignment requirements and exams. To assure instructor leeway, we'll look at how the course coordinator can encourage instructors and adjuncts to add their spin, knowledge, and experience to their specific sections - all while maintaining and delivering the baseline content for consistency and standardization. And finally, we'll look at the benefits of effective course coordination which can ensure seamless course continuity during times of disaster like COVID-19 and when instructors call in sick.

description: We theoretically consider the effect of the atomic source's momentum width on the efficiency of Bragg mirrors and beamsplitters and, more generally, on the phase sensitivity of Bragg pulse atom interferometers. By numerical optimization, we show that an atomic cloud's momentum width places a fundamental upper bound on the maximum transfer efficiency of a Bragg mirror pulse, and furthermore limits the phase sensitivity of a Bragg pulse atom interferometer. We quantify these momentum width effects, and precisely compute how mirror efficiencies and interferometer phase sensitivities vary as functions of Bragg order and source type. Our results and methodology allow for an efficient optimization of Bragg pulses and the comparison of different atomic sources, and will help in the design of large momentum transfer Bragg mirrors and beamsplitters for use in atom-based inertial sensors.

description: In den letzten Jahren sind viele Kinder und Jugendliche mit ihren Familien nach Deutschland geflüchtet. Ihre Integration ist von zentraler Bedeutung für ihr Leben heute und ihren weiteren Lebensweg. Wichtige Indikatoren einer erfolgreichen Integration sind das Zugehörigkeitsgefühl zu ihren Schulen, ihre Teilnahme an schulischen und außerschulischen Aktivitäten sowie ihre sozialen Kontakte. Dieser Bericht beleuchtet diese Indikatoren auf Basis der Daten des Sozio-oekonomischen Panels (SOEP), insbesondere der IAB-SOEP-Migrationsstichproben und der IAB-BAMF-SOEP-Befragung von Geflüchteten. Die Ergebnisse zeigen, dass die Integration von Zwölf-, 14und 17-Jährigen, die mit Familienangehörigen nach Deutschland gekommen sind, grundsätzlich auf einem guten Weg ist: Sie fühlen sich ihrer Schule zugehörig und besuchen vermehrt schulische Ganztags- sowie Hortangebote. Dadurch wird ihnen der ganztägige Kontakt mit Gleichaltrigen, die schon länger in Deutschland leben, ermöglicht. Die vergleichsweise geringe Beteiligung geflüchteter Kinder und Jugendlicher an Schul-AGs zeigt jedoch, dass das Potential noch nicht ausgeschöpft ist. Hier sollten Bemühungen verstärkt werden, um eine höhere Teilnahme zu erreichen. Auch bei außerschulischen Aktivitäten besteht weiteres Potential. So könnten etwa Sportvereine noch aktiver um eine Teilnahme geflüchteter Kinder und Jugendlicher werben.

description: A fall 2020 collaboration between the School of Business and Student Media/WGMU Radio inspired a new assignment and presentation medium for the BUS 303 - Developing Your Professional Skills, Advanced Elements course - a podcast. The goal of the assignment was to create podcasts on professional skills topics relevant to students and emerging professionals covered in the course such as emotional intelligence and leadership. The podcasts would be shared through WGMU radio programming to inform all Mason students. Creating the podcasts also required use of many professional skills including conducting research, practicing rhetorical awareness, organization and time management, and oral and written communication. The assignment description provides guidelines on podcast content, technical production, delivery, and supportive resources. The podcast project resulted in (an example podcast will be shared) a new engaging and informative format for student presentations that showcased soft skills, diversity, and included honest personal experiences that were relatable and at times moving.

description: Auf Grundlage der IAB-BAMF-SOEP-Befragung Geflüchteter in Deutschland vergleicht dieser Bericht die im Jahr 2016 geäußerten Erwartungen zu einer Erwerbstätigkeit in Deutschland mit der realisierten Beschäftigung im Jahr 2018. Die überwiegende Mehrheit der Geflüchteten hat im Jahr 2016 angenommen, mit hoher Wahrscheinlichkeit eine Beschäftigung in den kommenden zwei Jahren zu finden. Bei 54 Prozent aller Geflüchteten haben sich die Erwartungen erfüllt. Etwa 35 Prozent der Geflüchteten hatten im Jahr 2016 jedoch hohe Erwartungen und konnten sich diese nicht erfüllen. Die Ergebnisse legen nahe, dass sowohl strukturelle Bedingungen als auch individuelle Merkmale, wie beispielsweise fehlende Kinderbetreuung oder die psychische Gesundheit Geflüchteter, die Aufnahme einer Beschäftigung erschwert haben. Maßnahmen, wie zusätzliche Beratungs- und Hintergrundgespräche über den deutschen Arbeitsmarkt, ein geeignetes Angebot für Kinderbetreuung und die Unterstützung von Geflüchteten mit schlechterer psychischer Gesundheit könnten dazu beitragen, dass sich die Beschäftigungserwartungen von Geflüchteten häufiger erfüllen. Weitere Untersuchungen sind notwendig, um die zugrundeliegenden Mechanismen besser zu verstehen.

Art from within : an encounter with holocaust art from the Terezin ghetto
Creators: name: Meli, Sarah
Publisher: name: University of British Columbia
Year: 2013

description: Terezin, located in what is now called Prague, Czechoslovakia, functioned as a Holocaust ghetto for the incarceration of Jews during the Second World War. Creating an image of a ‘model camp’ for its detained elite Europeans of economic and intellectual wealth, certain leeway was given to mask the reality of the situation. Being allowed to teach art to children, having a Drawing Office, and providing an Art Workshop, resulted in Terezin being one of the ghettos/camps in which thousands of art pieces were produced by children, youths, and adults. With a focus on the artwork made between the period of 1942 and 1944, a number of images were studied in the archives of the United States Holocaust Memorial Museum, USA, as well as artifacts accessed through the Vancouver Holocaust Education Centre, Canada. As a non-Jewish, Mediterranean art educator trained in Western institutions with no known ties to those deported to Terezin, personal responses to the experience of the encounter were recorded while asking the Deleuzian instructive question of “how does it work?” rather than “what does it mean?.” The a/r/tographical practice was informed by and through, the journey that was taken to access the archives. In selecting seven works, notions of witnessing, intrusion, victimization, clash of religious values, and the unspoken aspects of the ‘typical’ are discussed. The process of understanding what the art became to the self through the encounter with original Terezin artwork, led to the production of an art piece that translates the connections found when sifting through the moments of being with camp art. Recommendations for further research include studies on art from and about the Holocaust camps and ghettos, on the education system that was designed and practiced in Terezin, as well as a recommendation of studying the music, literary, and theatre arts that were also practiced in the spaces of the researched Holocaust ghetto. Through an exploration of the variety of art forms and silent curricula of Terezin, such studies could convey the type, appreciation, and significance of cultural presence that secretly thrived and, furthermore, support connections with the voices of Holocaust deportees.

description: Die Bildungsabschlüsse von MigrantInnen werden typischerweise anhand der im Zielland geltenden Standards eingeordnet. Weniger Beachtung findet dagegen die Stellung, die diese Qualifikationen im jeweiligen Herkunftsland haben. In diesem Beitrag wird die mitgebrachte Bildung verschiedener Gruppen von Zugewanderten mit den Bildungsverteilungen des jeweiligen Herkunftslands und mit der Bildungsverteilung in Deutschland verglichen. Die Auswertungen zeigen, dass Geflüchtete im Vergleich zu den meisten anderen gegenwärtigen Migrantengruppen über eine im Schnitt geringere formale Bildung verfügen. Die Ergebnisse belegen außerdem, dass Geflüchtete mit einem für deutsche Verhältnisse niedrigen absoluten Bildungsniveau besser gebildet sein können als die Mehrheit in ihrer Herkunftsgesellschaft. Dies kann sich positiv auf den Integrationserfolg in Deutschland auswirken.

description: We present a novel approximation for two interacting magnetic impurities immersed into a noninteracting metallic host. The scheme is based on direct perturbation theory in the hybridization between the impurity and band electrons. This two-impurity enhanced noncrossing approximation (TIE) fully incorporates the indirect interaction between the impurities which are mediated by the conduction electrons as well as additional arbitrary direct interaction matrix elements. We qualify the approximation by investigating the uncoupled case and conclude the TIE to be equally accurate as its single impurity counterpart. The physical properties of the two-impurity Anderson model are first investigated in some limiting cases. In a regime, where each of the uncoupled two impurities would exhibit a pronounced Kondo effect, we ignore the indirect coupling via the conduction band and only incorporate direct interactions. For a ferromagnetic direct exchange coupling, the system displays a behavior similar to a spin-one Kondo effect, while an antiferromagnetic coupling competes with the Kondo effect and produces a pseudogap in the many-body Kondo resonance of the single-particle spectral function. Interestingly, a direct one-particle hopping also produces a pseudogap but additionally pronounced side-peaks emerge. This gap is characteristically different from the case with antiferromagnetic coupling, since it emerges as a consequence of distinct Kondo effects for the bonding and anti-bonding orbital, i.e.\ it reflects a splitting of even and odd parity states.For the general case of only indirect coupling the results show signatures of all the previously discussed limiting cases as function of the impurity-impurity distance. We are led to the conclusion that the well known Doniach-scenario captures essential aspects this model, but the details especially at small distances are more complicated.

description: The spectrum of baryons containing three b quarks is calculated in nonperturbative QCD, using the lattice regularization. The energies of ten excited bbb states with J^P = 1/2^+, 3/2^+, 5/2^+, 7/2^+, 1/2^-, and 3/2^- are determined with high precision. A domain-wall action is used for the up-, down- and strange quarks, and the bottom quarks are implemented with NRQCD. The computations are done at lattice spacings of a \approx 0.11 fm and a \approx 0.08 fm, and the results demonstrate the improvement of rotational symmetry as a is reduced. A large lattice volume of (2.7 fm)^3 is used, and extrapolations of the bbb spectrum to realistic values of the light sea-quark masses are performed. All spin-dependent energy splittings are resolved with total uncertainties of order 1 MeV, and the dependence of these splittings on the couplings in the NRQCD action is analyzed.

description: In this paper, we emphasize that a UV SUSY-breaking theory can be realized either linearly or nonlinearly. Both realizations form the dual descriptions of the UV SUSY-breaking theory. Guided by this observation, we find subtle identities involving the Goldstino field and matter fields in the standard nonlinear realization from trivial ones in the linear realization. Rather complicated integrands in the standard nonlinear realization are identified as total-divergences. Especially, identities only involving the Goldstino field reveal the self-consistency of the Grassmann algebra. As an application of these identities, we prove that the nonlinear Kahler potential without or with gauge interactions is unique, if the corresponding linear one is fixed. Our identities pick out the total-divergence terms and guarantee this uniqueness.

description: The widely used density matrix renormalization group (DRMG) method often fails to converge in systems with multiple length scales, such as lattice discretizations of continuum models and dilute or weakly doped lattice models. The local optimization employed by DMRG to optimize the wave function is ineffective in updating large-scale features. Here we present a multigrid algorithm that solves these convergence problems by optimizing the wave function at different spatial resolutions. We demonstrate its effectiveness by simulating bosons in continuous space, and study non-adiabaticity when ramping up the amplitude of an optical lattice. The algorithm can be generalized to tensor network methods, and be combined with the contractor renormalization group (CORE) method to study dilute and weakly doped lattice models.

description: We present a detailed statistical analysis of the alignment of polarizations of radio sources at high redshift. We use the JVAS/CLASS 8.4-GHz surveys for our study. This study is motivated by the puzzling signal of alignment of polarizations from distant quasars at optical frequencies. We explore several different cuts on the polarization flux for our analysis. We find that the entire data shows a very significant signal of alignment on very large distance scales of order 500 Mpc. The alignment starts to decay only at much larger distances of order Gpc. If we only consider data with polarization flux greater than 1 mJy, we find alignment at distance scales less than 150 Mpc. We also find that data with polarization flux less than 0.5 mJy does not show significant alignment. Similar results are seen for data with degree of polarization less than 0.01, although here a mild signal of alignment is observed for a narrow range of angular separations. We argue that the signal cannot be explained in terms of bias due to systematic errors in removal of instrumental polarization. We also find that the degree of polarization shows a strong negative correlation with the total flux. The data appears to fall into two classes, one of which shows such a correlation. The remaining set, which has total flux greater than 100 mJy and degree of polarization lying between 0.01 and 0.1, shows a more random behaviour. The latter set is also found to show no alignment whereas the first set shows a very strong polarization alignment.

description: Der europäischen Bankenunion fehlt bisher die dritte Säule: ein gemeinsamer Sicherungsfonds für die Einlagen von SparerInnen bei Banken. Wie diese Studie zeigt, könnte dies im Zuge der wirtschaftlichen Auswirkungen der Corona-Pandemie Nachteile mit sich bringen. Ein Szenario, in dem es durch eine Insolvenzwelle bei Unternehmen zu Kredit- und Einlagenausfällen von insgesamt sechs Prozent über ein Jahr kommt, würde die nationale Einlagensicherung in Deutschland überfordern. Selbst wenn der Fiskus einspringt und alle Einlagen sichert, wäre eine Europäische Einlagensicherung (EDIS) im Vergleich die bessere Variante: Mit ihr würde der private Konsum um 20 Prozent weniger und die Kreditvergabe um rund zehn Prozent weniger stark sinken als im Falle einer staatlichen Rettung, die zudem die Staatsverschuldung deutlich erhöht. Eine stärkere Risikoteilung spricht somit auch aus deutscher Sicht für eine zügige EDIS-Einführung. Allerdings ist es wichtig, einen effizienten Einzahlungsmechanismus zu entwickeln, um die Belastung für die Banken möglichst gering zu halten. Zudem sollten Vorkehrungen getroffen werden, um einer erhöhten Risikobereitschaft der Banken infolge der EDIS-Einführung vorzubeugen.

Transport properties of the rough hard sphere fluid
Creators: name: Kravchenko, Olga
Publisher: name: University of British Columbia
Year: 2013

description: This thesis examines the dynamics and physical properties of the rough hard sphere fluid (RHSF). The RHSF model consists of spherical particles with well-defined radii that exchange linear and angular momenta upon collision. The simplicity of this model allows for a precise theoretical description that provides a basis for studying fluid properties on the most fundamental level. Extensive molecular dynamics calculations were made of transport properties as functions of density, tracer particle size, and degree of rotational-translational coupling. Results were compared with the smooth hard sphere case and it was found that transport coefficients change significantly due to rotational-translational coupling, becoming stronger with an increase in coupling. Tracer diffusion coefficients were examined for a range of tracer sizes and at various densities. As tracer particles become larger, their diffusion coefficient moves from an Enskog (molecular) to a Stokes-Einstein (hydrodynamic) functional form; the latter depends upon the boundary condition at the surface of the tracer. These boundary conditions for the RHSF are directly proportional to the degree of rotational-translational energy exchange, and can be tuned from "slip" to "stick" values. The validity of several kinetic theory equations have been examined as functions of density and translational-rotational coupling. At very low densities, Boltzmann theory was accurate even at low order except for describing the dependence upon rotational-translational coupling, where low order expansions are less accurate. Enskog theory performed well at low and moderate densities but deviated at larger densities, as expected. For thermal conductivity as a function of translational-rotational coupling even the qualitative behavior was incorrect. The Enskog predictions for diffusion were also found to be quite poor at low order. Finally, motivated by the results of the thesis, experimental diffusion coefficient data were analyzed, especially for nanoparticles. It was shown that defining the correct radius is crucial for describing such systems. In addition, a new formula for predicting tracer diffusion was tested.

description: We investigate the influence of the electron-phonon interaction on the decay dynamics of a quantum dot coupled to an optical microcavity. We show that the electron-phonon interaction has important consequences on the dynamics, especially when the quantum dot and cavity are tuned out of resonance, in which case the phonons may add or remove energy leading to an effective non-resonant coupling between quantum dot and cavity. The system is investigated using two different theoretical approaches: (i) a second-order expansion in the bare phonon coupling constant, and (ii) an expansion in a polaron-photon coupling constant, arising from the polaron transformation which allows an accurate description at high temperatures. In the low temperature regime we find excellent agreement between the two approaches. An extensive study of the quantum dot decay dynamics is performed, where important parameter dependencies are covered. We find that in general the electron-phonon interaction gives rise to a greatly increased bandwidth of the coupling between quantum dot and cavity. At low temperature an asymmetry in the quantum dot decay rate is observed, leading to a faster decay when the quantum dot has a larger energy than to the cavity. We explain this as due to the absence of phonon absorption processes. Furthermore, we derive approximate analytical expressions for the quantum dot decay rate, applicable when the cavity can be adiabatically eliminated. The expressions lead to a clear interpretation of the physics and emphasizes the important role played by the effective phonon density, describing the availability of phonons for scattering, in quantum dot decay dynamics. Based on the analytical expressions we present the parameter regimes where phonon effects are expected to be important. Also, we include all technical developments in appendices.

description: Chemical investigation of the whole plant of Sauropus hirsutus Beille led to the isolation of eight quinolines and two known flavonoids. Furthermore, five quinolines were new, two were reported in plant for the first time and one was known. Cytotoxicity evaluation against cholangiocarcinoma, KKU-M156, showed that the most active compound was 4-hydroxy-6-methoxy-7,8-methylenedioxyquinaldine (IC50 20.54 ± 6.82 µM) which was a little more active than the cisplatin standard (IC50 24.39 ± 1.14 µM).

description: The construction of type II Backlund transformation for the sine-Gordon and the Tzitzeica-Bullough-Dodd models are obtained from gauge transformation. An infinite number of conserved quantities are constructed from the defect matrices. This guarantees that the introduction of type II defects for these models does not spoil their integrability. In particular, modified energy and momentum are derived and compared with those presented in recent literature.

description: We have studied extensively phenomenological implications in a specific model of brane inflation driven by background supergravity, via thermal history of the universe and leptogenesis pertaining to the particle physics phenomenology of the early universe. Using the one loop corrected inflationary potential we have investigated for the analytical expression as well as the numerical estimation for brane reheating temperature for standard model particles. This results in some novel features of reheating from this type of inflation which have serious implications in the production of heavy Majorana neutrinos needed for leptogenesis through the reheating temperature. We have also derived the expressions for the gravitino abundance during reheating and radiation dominated era. We have further estimated different parameters at the epoch of phase transition and revealed their salient features. At the end we have explicitly given an estimate of the amount of CP violation through the effective CP phase which is related to baryon asymmetry as well as gravitino dark matter abundance.
