description: Differential astrometry measurements from the Palomar High-precision Astrometric Search for Exoplanet Systems have been combined with lower precision single-aperture measurements covering a much longer timespan (from eyepiece measurements, speckle interferometry, and adaptive optics) to determine improved visual orbits for 20 binary stars. In some cases, radial velocity observations exist to constrain the full three-dimensional orbit and determine component masses. The visual orbit of one of these binaries---alpha Com (HD 114378)---shows that the system is likely to have eclipses, despite its very long period of 26 years. The next eclipse is predicted to be within a week of 2015 January 24.

description: We discuss alternative homogeneous electron gas systems in which a finite number $n$ of electrons are confined to a $D$-dimensional sphere. We derive the first few terms of the high-density ($r_s\to0$, where $r_s$ is the Seitz radius) energy expansions for these systems and show that, in the thermodynamic limit ($n\to\infty$), these terms become identical to those of $D$-dimensional jellium.

description: Mittels der retrospektiven Analyse der Daten von 900 Patientinnen mit invasivem Mammakarzinom und durchgeführter SLNB wurden mögliche Risikofaktoren für den axillären Lymphknotenstatus identifiziert. Zusätzlich wurde eine Überlebenszeitanalyse durchgeführt. Die Tumorgröße war im Kollektiv der stärkste unabhängige Risikofaktor für den axillären Lymphknotenstatus. Weiterhin konnte der axilläre Lymphknotenstatus auch als unabhängiger Risikofaktor für das rezidivfreie Überleben bestätigt werden. Darüberhinaus schien auch das Grading einen deutlichen Einfluss auf den SLN-Status zu haben.

description: The interplay between the structural and magnetic phase transitions occurring in the Fe-based pnictide superconductors is studied within a Ginzburg-Landau approach. We show that the magnetoelastic coupling between the corresponding order parameters is behind the salient features observed in the phase diagram of these systems. This naturally explains the coincidence of transition temperatures observed in some cases as well as the character (first or second-order) of the transitions. We also show that magnetoelastic coupling is the key ingredient determining the collinearity of the magnetic ordering, and we propose an experimental criterion to distinguish between a pure elastic from a spin-nematic-driven structural transition.

description: The Palomar High-precision Astrometric Search for Exoplanet Systems (PHASES) monitored 51 subarcsecond binary systems to evaluate whether tertiary companions as small as Jovian planets orbited either the primary or secondary stars, perturbing their otherwise smooth Keplerian motions. Twenty-one of those systems were observed 10 or more times and show no evidence of additional companions. A new algorithm is presented for identifying astrometric companions and establishing the (companion mass)-(orbital period) combinations that can be excluded from existence with high confidence based on the PHASES observations, and the regions of mass-period phase space being excluded are presented for 21 PHASES binaries.

description: In this paper, we present a formulation of the classical theory of Fermionic (anticommuting) fields, which fits into the general framework proposed by K.Fredenhagen, M.Duetsch and R.Brunetti. It was inspired by the recent developments in perturbative algebraic quantum field theory and allows for a deeper structural understanding also on the classical level. We propose a modification of this formalism that allows to treat also Fermionic fields. In contrast to other formulations of classical theory of anticommuting variables, we don't introduce additional Grassman degrees of freedom. Instead the anticommutativity is introduced in a natural way on the level of functionals. Moreover our construction incorporates the functional-analytic and topological aspects, which is usually neglected in the treatments of anticommuting fields. We also give an example of an interacting model where our framework can be applied.

description: (Abridged) Differential astrometry measurements from the Palomar High-precision Astrometric Search for Exoplanet Systems (PHASES) are used to constrain the astrometric orbit of the previously known lesssim 2 day subsystem in the triple system 63 Gem A and have detected a previously unknown 2 year Keplerian wobble superimposed on the visual orbit of the much longer period (213 years) binary system HR 2896. The very small astrometric perturbation caused by the inner pair in 63 Gem A stretches the limits of current astrometric capabilities, but PHASES observations are able to constrain the orientation of the orbit. The two bright stars comprising the HR 2896 long period (213 year) system have a combined spectral type of K0III and the newly detected object's mass estimate places it in the regime of being a M dwarf. The motion of the stars are slow enough that their spectral features are always blended, preventing Doppler studies. The PHASES measurements and radial velocities (when available) have been combined with lower precision single-aperture measurements covering a much longer timeframe to improve the characterization of the long period orbits in both binaries. The visual orbits of the short and long period systems are presented for both systems, and used to calculate two possible values of the mutual inclinations between inner and outer orbits of 152 pm 12 degrees or a less likely value of 31 pm 11 degrees for 63 Gem A and 10.2 pm 2.4 degrees or 171.2 pm 2.8 degrees for HR 2896. The first is not coplanar, whereas the second is either nearly coplanar or anti-coplanar.

description: Organizational contextual factors, influencing the implementation of any new system, either in a business enterprise or an education institution, should be taken into consideration when comprehensive implementation of new system is considered.  This scoping review was conducted with the aim of identifying the effective organizational factors in adopting e-learning. Data collection was carried out by searching the related keywords Web of sciences (WOS) and Scopus, with no limitation on date of publication. Different search strategies were applied to find the related articles. The content of the articles was analyzed by using a qualitative synthesis approach, and according to the inclusion and exclusion criteria. The search resulted in 21 articles eligible for analysis, which showed 20 effective organizational factors in adopting e-learning. These factors were classified in to four main themes: 1) institutional infrastructure and compatibility, 2) resources allocation, 3) organizational support and monitoring, and 4) motivation, innovation & change management. The results also showed that Unified Theory of Acceptance Model (UTAUT) was the most prevalent adoption theory in the studies, followed by Technology Acceptance Model (TAM). This study reviewed the literature pertaining to the organizational effective factors in adopting e-learning. The results acknowledged that organizational factors are the backbone of e-learning adoption in universities and institutions. This fact should be taken into consideration by mangers and policy makers, especially in developing countries.

description: For SU(3) lattice gauge theory we study properties of static quark sources represented by local Polyakov loops. We find that for temperatures both below and above T_c coherent domains exist where the phases of the local loops have similar values in the vicinity of the center values 0, +/- 2 pi/3. The cluster properties of these domains are studied numerically. We demonstrate that the deconfinement transition of SU(3) may be characterized by the percolation of suitably defined clusters.

description: We derive a simple analytical expression for the two-body force in a sub-class of MOND-like theories and make testable predictions in the modification to the two-body orbital period, shape, and precession rate, and escape speed etc. We demonstrate the applications of the modified Kepler's law in the timing of satellite orbits around the Milky Way, and checking the feasibility of MOND in the orbit of Large Magellanic Cloud, the M31 galaxy, and the merging Bullet Clusters. MOND appears to be consistent with satellite orbits although with a tight margin. Our results on two-bodies are also generalized to restricted three-body, many-body problems, rings and shells.

A statistical investigation of how slope affects a wildfire's rate of spread
Creators: name: Goetz, Geoffrey Owen
Publisher: name: University of British Columbia
Year: 2021

description: Modelling wildfire spread from data collected on various slopes and across different fuel types is an important way to understand how different parameters influence the speed at which these fires travel. Fitting this data to statistical models could be used to provide accurate fire spread predictions and can influence the way in which fire fighters may combat a wildfire. The objective of this thesis is to establish a model that describes the influence of slope on a fire's resulting rate of spread in three different fuel types. We present the analysis of data from both small scale experimental fires and test burns conducted in the field in a natural landscape. We use non-linear regression and generalized additive models to create this model, using current rate of spread models as our foundation. An analysis on the influence of slope on the rate of spread travelling downhill at the heel end of a fire is also provided.

A PROBABILISTIC APPROACH TO UNCERTAINTY IN TURBINE EFFICIENCY MEASUREMENT
Creators: name: Bhatnagar, Lakshya
Publisher: name: Purdue University Graduate School
Year: 2022
Subjects: Mechanical engineering not elsewhere classified
Numerical modelling and mechanical characterisation

description: Efficiency is an essential metric for assessing turbine performance. Modern turbines rely heavily on numerical computational fluid dynamic (CFD) tools for design improvement. With more compact turbines leading to lower aspect ratio airfoils, the influence of secondary flows is significant on performance. Secondary flows and detached flows, in general, remain a challenge for commercial CFD solvers; hence, there is a need for high fidelity experimental data to tune these solvers used by turbine designers. Efficiency measurements in engine-representative test rigs are challenging for multiple reasons; an inherent problem to any experiment is to remove the effects specific to the turbine rig. This problem is compounded by the narrow uncertainty band required, ideally less than 0.5% uncertainty, to detect the incremental improvements achieved by turbine designers. Efficiency measurements carried out in engine-representative turbine rigs have traditionally relied upon strong assumptions, such as neglecting heat transfer effects. Furthermore, prior to this research there was no framework to compute uncertainty propagation that combines both inputs from experiments and computational tools. This dissertation presents a comprehensive methodology to obtain high-fidelity adiabatic efficiency data in engine-representative turbine facilities. This dissertation presents probabilistic sampling techniques to allow for uncertainty propagation. The effect of rig-specific effects such as heat transfer and gas properties, on efficiency is demonstrated. Sources of uncertainty are identified, and a framework is presented which divides the sources into bias and stochastic. The framework allows the combination of experimental and numerical uncertainty. The accuracy of temperature and aerodynamic pressure probes, used for efficiency determination, is quantified. Corrections for those effects are presented that rely on hybrid numerical and experimental methods. Uncertainty is propagated through these methods using numerical sampling. Finally, two test cases are presented, a stator vane in an annular cascade and a two-stage turbine in a rotating rig. The performance is analyzed using the methods and corrections developed. The uncertainty on the measured efficiency is similar to literature but the uncertainty framework allows an uncertainty estimate on the adiabatic efficiency.
A mixed method study of strategies adopted by postgraduate teachers to mitigate the impact of the digital divide

Year: 2023

description: The digital divide, which refers to disparities in accessing and utilising digital technologies, has emerged as a noteworthy issue in education, especially in the context of postgraduate studies. The research, employing a mixed-method approach, investigates the methods employed by postgraduate educators to address the challenges posed by the digital divide in their teaching approaches. The study utilised a concurrent triangulation design, allowing for the simultaneous collection and analysis of qualitative and quantitative data. Initial data collection and analysis occurred in tandem with conducting in-depth interviews with postgraduate teachers, followed by thematic analysis. The data was collected and analysed from 25 postgraduate teachers who work in diverse educational settings. Findings revealed that postgraduate teachers adopted various pedagogical, technological, and socio-cultural strategies to address the challenges of the digital divide. Pedagogical strategies included using diverse instructional strategies, adapting teaching methods, and leveraging prior knowledge of students. Technological strategies encompassed utilising available digital resources online platforms and promoting digital literacy along with Free Open Source Software and Open Educational Resources among students. Socio-cultural strategies included building collaborative networks, creating inclusive classroom environments, and fostering a positive teacher-student relationship. The findings of this study contribute to the understanding of how postgraduate teachers address the digital divide in their teaching practices and highlight the importance of innovative strategies to ensure equitable access to digital technologies in education.

Livable neighbourhoods in multicultural cities : immigrant women’s experiences and preferences
Creators: name: Ebneshahidi, Marjanossadat
Publisher: name: University of British Columbia
Year: 2021

description: Immigrant women’s needs and their experiences of neighbourhood livability in multicultural countries such as Canada have been demonstrated to be worthy of study because they face barriers to settlement, accessing supports, and social integration. This dissertation, therefore, aims to achieve a deeper knowledge of immigrant women’s experiences in residential neighbourhoods and specifically asks the main question of what makes a neighbourhood livable for them in multicultural cities? This study was conducted in the Metro Vancouver region of British Columbia, Canada, using mixed methods. The findings of this study have been organized into three major manuscript-based chapters. Using a survey, the first manuscript examines how immigrant women perceive the importance of livability factors and tests the combined effect of those factors on their neighbourhood selection. The results stress the importance of neighbourhood safety, housing affordability and quality, and proximity to public transit. This manuscript also argues that immigrant women who valued socio-cultural amenities/events, ethnolinguistic signs, and social contacts among neighbours preferred to live close to co-ethnics. Finally, this study reveals that participants who highly valued the factors of nightlife and proximity to workplaces, restaurants, and cafes had a tendency toward Vancouver neighbourhoods, while those who valued the factors of proximity to schools and daycares, police stations, and having friendly neighbours had a tendency toward suburban neighbourhoods. Data for the second manuscript was collected through interviews. Exploring how newcomer women experience the social aspects of neighbourhood livability, this manuscript identifies four potential actions to make neighbourhoods socially livable for newcomer women: boosting social cohesion, building multicultural neighbourhoods, developing settlement supports, and improving neighbourhood safety. The research data in the final manuscript was drawn from mental mapping exercises, investigating how newcomer women perceive their physical neighbourhood boundaries. The results of this manuscript demonstrate the contribution of the following four main amenities to shaping the perceived neighbourhood boundaries and livability: lively social and community-based spaces, inviting green spaces, shopping streets and shopping malls, and ethnic markets. According to these results, I proposed a guiding framework in the concluding chapter, including ten dimensions, for the design and development of more livable neighbourhoods in multicultural cities.

description: The COVID-19 pandemic has precipitated unprecedented disruptions in the realm of education, compelling governments, education systems, and educators worldwide to adapt rapidly to alternative modes of delivery while striving to maintain the quality of education. As the crisis persists, numerous uncertainties loom over the future of schooling, including concerns about student re-engagement post-pandemic, the viability of institutions amid declining enrollments and potential dropouts, and the logistical challenges posed by social distancing guidelines. Additionally, there is widespread apprehension surrounding the readiness and acceptance of technology for remote learning, exacerbated by unreliable infrastructure and the lingering trauma experienced by parents and guardians. Moreover, the affordability of online classes and the capacity of instructors, parents, and students to navigate digital platforms remain pressing issues. Despite these challenges, educational institutions are actively embracing online blended learning models in anticipation of continued disruptions.

This abstract highlights the multifaceted challenges faced by the education sector in the wake of the COVID-19 pandemic and underscores the urgent need for innovative solutions to sustain quality education provision. Addressing concerns surrounding student re-engagement, institutional viability, technological readiness, and financial accessibility is paramount for ensuring equitable access to education in the post-pandemic era. By acknowledging and addressing these challenges, stakeholders can work collaboratively to navigate the evolving landscape of education and mitigate the adverse impacts of the pandemic on learning outcomes

description: The Weierstrass random walk is a paradigmatic Markov chain giving rise to a Lévy-type superdiffusive behavior. It is well known that Special Relativity prevents the arbitrarily high velocities necessary to establish a superdiffusive behavior in any process occurring in Minkowski spacetime, implying, in particular, that any relativistic Markov chain describing spacetime phenomena must be essentially Gaussian. Here, we introduce a simple relativistic extension of the Weierstrass random walk and show that there must exist a transition time $t_c$ delimiting two qualitative distinct dynamical regimes: the (non-relativistic) superdiffusive Lévy flights, for $ t < t_c$, and the usual (relativistic) Gaussian diffusion, for $t>t_c$. Implications of this crossover between different diffusion regimes are discussed for some explicit examples. The study of such an explicit and simple Markov chain can shed some light on several results obtained in much more involved contexts.

description: Cyanobacteria have raised great interest in biotechnology due to their potential for a sustainable, photosynthesis-driven production of fuels and value-added chemicals. This has led to a concomitant development of molecular tools to engineer the metabolism of those organisms. In this regard, however, even cyanobacterial model strains lag behind compared to their heterotrophic counterparts. For instance, replicative shuttle vectors that allow gene transfer independent of recombination into host DNA are still scarce. Here, we introduce the pSOMA shuttle vector series comprising 10 synthetic plasmids for comprehensive genetic engineering of Synechocystis sp. PCC 6803. The series is based on the small endogenous plasmids pCA2.4 and pCB2.4, each combined with a replicon from Escherichia coli, different selection markers as well as features facilitating molecular cloning and the insulated introduction of gene expression cassettes. We made use of genes encoding green fluorescent protein (GFP) and a Baeyer–Villiger monooxygenase (BVMO) to demonstrate functional gene expression from the pSOMA plasmids in vivo. Moreover, we demonstrate the expression of distinct heterologous genes from individual plasmids maintained in the same strain and thereby confirmed compatibility between the two pSOMA subseries as well as with derivatives of the broad-host-range plasmid RSF1010. We also show that gene transfer into the filamentous model strain Anabaena sp. PCC 7120 is generally possible, which is encouraging to further explore the range of cyanobacterial host species that could be engineered via pSOMA plasmids. Altogether, the pSOMA shuttle vector series displays an attractive alternative to existing plasmid series and thus meets the current demand for the introduction of complex genetic setups and to perform extensive metabolic engineering of cyanobacteria.

description: In the inflationary scenario of loop quantum cosmology in the presence of inverse-volume corrections, we give analytic formulas for the power spectra of scalar and tensor perturbations convenient to compare with observations. Since inverse-volume corrections can provide strong contributions to the running spectral indices, inclusion of terms higher than the second-order runnings in the power spectra is crucially important. Using the recent data of cosmic microwave background and other cosmological experiments, we place bounds on the quantum corrections.

description: Introduction: Research has scrutinized the role of different HRM practices in Project-based Organizations (PBOs) mostly in terms of project success and articulated the challenges of traditional HRM to reconcile with the project context. Nevertheless, HRM practices have been addressed less in PBOs with a practice-based research lens. Particularly, the role of tempo-spatial nexus in shaping such practices in this organizational form has been under-researched, although PBOs provide a very suitable context for doing so. Methods: Drawing upon a comparative case study in the oil and gas industry of Scotland and adopting a practice-based approach, this research aims to shed light on how HRM practices are shaped and re-shaped in the project-based context. The study, specifically, scrutinizes the role of temporality and space in the formation, adoption and adaptation of HRM practices in these organizational forms. Results and discussion: The findings reveal that project characteristics, specifically their duration, size and technical properties, induce different temporalities that along with different work locations and inter-organizational relationships, impact HRM practices as a threefold structure.

description: Background and Objectives: Transfusion of red cell concentrates is a key component of medical therapy. To investigate the complex transfusion-associated biochemical and physiological processes as well as potential risks for human recipients, animal models are of particular importance. This scoping review summarizes existing large animal transfusion models for their ability to model the physiology associated with the storage of erythrocyte concentrates. Materials and Methods: The electronic databases PubMed, EMBASE, and Web of Science were systematically searched for original studies providing information on the intravenous application of erythrocyte concentrates in porcine, ovine, and canine animal models. Results: A total of 36 studies were included in the analysis. The majority of porcine studies evaluated hemorrhagic shock conditions. Pig models showed high physiological similarities with regard to red cell physiology during early storage. Ovine and canine studies were found to model typical aspects of human red cell storage at 42 days. Only four studies provided data on 24 h in vivo survival of red cells. Conclusions: While ovine and canine models can mimic typical human erythrocyte storage for up to 42 days, porcine models stand out for reliably simulating double-hit pathologies such as hemorrhagic shock. Large animal models remain an important area of translational research since they have an impact on testing new pharmacological or biophysical interventions to attenuate storage-related adverse effects and allow, in a controlled environment, to study background and interventions in dynamic and severe disease conditions.

description: Objective: To identify facilitators and barriers and derive concrete measures towards better workplace integration of migrants working in the German healthcare sector. Design: Two-centre cross-sectional quantitative online survey of experiences of discrimination among healthcare professionals with a migration history in two large German university hospitals. Participants: 251 participants fully completed the questionnaires. Main outcome measures: Experiences of discrimination and perception of inequality. Results: Fifty-five percent of migrant health workers had had at least some command of German before arriving in Germany. Members of all professional groups surveyed expressed experiences of discrimination related to language, nationality, race/ethnicity, and sex/gender. The proportions of staff with experiences of discrimination by peers differed significantly among occupational roles, with nurses and technologists having the most experiences of discrimination. The perception of inequality was reported more frequently than experiences of discrimination and had a negative impact on workplace satisfaction. Specifically, the compulsion to compete was a frequent feeling stated by participants. Conclusion: The mechanisms of discrimination and structural inequality revealed by our survey could inform specific measures, for example at the management level, to increase workplace satisfaction and attract migrant health workers in the long term.
