description: The possibility of improving on the usual multivariate normal confidence was first discussed in Stein (1962). Using the ideas of shrinkage, through Bayesian and empirical Bayesian arguments, domination results, both analytic and numerical, have been obtained. Here we trace some of the developments in confidence set estimation.

description: From SAE Level 3 of automation onwards, drivers are allowed to engage in activities that are not directly related to driving during their travel. However, in level 3, a misunderstanding of the capabilities of the system might lead drivers to engage in secondary tasks, which could impair their ability to react to challenging traffic situations.
 Anticipating driver activity allows for early detection of risky behaviors, to prevent accidents. To be able to predict the driver activity, a Deep Learning network needs to be trained on a dataset. However, the use of datasets based on simulation for training and the migration to real-world data for prediction has proven to be suboptimal. Hence, this paper presents a real-world driver activity dataset, openly accessible on IEEE Dataport, which encompasses various activities that occur in autonomous driving scenarios under various illumination and weather conditions. Results from the training process showed that the dataset provides an excellent benchmark for implementing models for driver activity recognition.

description: The central region of the Milky Way provides a unique laboratory for a systematic, spatially-resolved population study of evolved massive stars of various types in a relatively high metallicity environment. We have conducted a multi-wavelength data analysis of 180 such stars or candidates, most of which were drawn from a recent large-scale HST/NICMOS narrow-band Pa-a survey, plus additional 14 Wolf-Rayet stars identified in earlier ground-based spectroscopic observations of the same field. The multi-wavelength data include broad-band IR photometry measurements from HST/NICMOS, SIRIUS, 2MASS, Spitzer/IRAC, and Chandra X-ray observations. We correct for extinctions toward individual stars, improve the Pa-a line equivalent width measurements, quantify the substantial mid-IR dust emission associated with WC stars, and find X-ray counterparts. In the process, we identify 10 foreground sources, some of which may be nearby cataclysmic variables. The WN stars in the Arches and Central clusters show correlations between the Pa-a equivalent width and the adjacent continuum emission. However, the WN stars in the latter cluster are systematically dimmer than those in the Arches cluster, presumably due to the different ages of the two clusters. In the EW-magnitude plot, WNL stars, WC stars and OB supergiants roughly fall into three distinct regions. We estimate that the dust mass associated with individual WC stars in the Quintuplet cluster can reach 1e-5 M, or more than one order of magnitude larger than previous estimates. Thus WC stars could be a significant source of dust in the galaxies of the early universe. Nearly half of the evolved massive stars in the GC are located outside the three known massive stellar clusters. The ionization of several compact HII regions can be accounted for by their enclosed individual evolved massive stars, which thus likely formed in isolation or in small groups.

Different modes of thought during the creative process
Creators: name: Ellamil, Melissa Marie
Publisher: name: University of British Columbia
Year: 2010

description: Creativity is most often defined as the ability to produce ideas that are both novel and useful. Consistent with this twofold definition, psychological theories have suggested that creativity involves a twofold process characterized by a generative (or associative) component that facilitates the production of novel ideas, and an evaluative (or analytic) component that enables the assessment of these ideas as to their usefulness. To investigate this, the present study employed a novel paradigm that was specifically designed to allow for separately examining the generative and evaluative components of the creative process. Functional magnetic resonance imaging (fMRI) was used to identify the contribution of particular brain regions to creative generation and evaluation. Participants were presented with short book descriptions and, using an fMRI-compatible drawing tablet, designed corresponding book cover illustrations while alternating between the generation and evaluation of ideas. Creative generation and evaluation were associated with recruitment of distinct neural circuits, with generation preferentially recruiting medial temporal lobe regions, and evaluation showing joint recruitment of executive and default network regions. These findings suggest that the medial temporal lobe may play an important role in the generation of novel ideas, and that creative evaluation may extend beyond deliberate and cognitive analytical processes supported by executive resources to include spontaneous, affective, and visceroceptive analytical processes. In summary, separating and alternating between generative and evaluative modes during a creative task helped to provide a better characterization of the contributions of creativity-related brain areas to the creative process, which had previously only been inferred indirectly. The results of this study suggest that creative thinking recruits a unique configuration of neural processes not typically used together in more traditional tasks.

description: A biological process is an essential secondary treatment in wastewater treatment, where bacteria degrade organic substances. It is referred to as an activated sludge process. Two models in this thesis are selected to represent an activated sludge process. One is a 4 *4 model and the other is the benchmark Activated Sludge Model no.1 (ASM1). The main objective of this thesis is to design and develop an adaptive fuzzy controller to control an activated sludge process with unknown influent flow and disturbances. Lyapunov’s direct method is used for theoretically analyzing the dynamic system with control. The fuzzy system works as a nonlinear approximator, and an adaptive control is designed to adapt the parameters of the fuzzy sets in order to guarantee stability. A supervisory control is developed to improve the performance of the fuzzy approximator. Also, parameter projection is used for the adaptive parameters to ensure robustness to disturbances by bounding the parameter growth. Simulations of the control with both activated sludge models show improved performance compared to PI controls.

description: We study the variational solution of generic interacting fermionic lattice systems using fermionic Gaussian states and show that the process of "gaussification", leading to a nonlinear closed equation of motion for the covariance matrix, is locally optimal in time by relating it to the time-dependent variational principle. By linearising our nonlinear equation of motion around the ground-state fixed point we describe a method to study low-lying excited states leading to a variational method to determine the dispersion relations of generic interacting fermionic lattice systems. This procedure is applied to study the attractive and repulsive Hubbard model on a two-dimensional lattice.
title: Comparison of Curriculum Content on Behavioral Strategies for Managing Anxious Clients in Associate and Baccalaureate Degree Dental Hygiene Programs in the United States

description: Dental anxiety, a pervasive problem in the general population, is an important client management concern for dental hygienists. This study sought to determine the type and amount of instruction in United States dental hygiene programs in terms of behavioral strategies for the management of anxious clients, the difference in instruction between associate and baccalaureate degree dental hygiene programs, and the opinions of dental hygiene educators regarding these strategies. A self-designed, 19-item questionnaire entitled the King Behavioral Management Questionnaire was used to obtain data on a sample of 210 accredited dental hygiene programs. Part one of the questionnaire consisted of questions pertaining to behavioral instruction; part two consisted of statements about behavioral strategies that allowed respondents to express their opinions using a Likert scale. Results revealed that 86 percent of programs surveyed (n= 146) teach behavioral strategies for managing client anxiety. Types of strategies taught and percentage of programs teaching them were informational provision (96% ), distraction (51%), modeling (51%), relaxation (62%) and hypnosis (7%). Chi-square analyses revealed no significant relationships between associate and baccalaureate programs relating to the type of behavioral strategies taught. The Z hypothesis test revealed that baccalaureate degree programs spend significantly more time on teaching behavioral strategies for managing client anxiety than associate degree programs. Frequency tabulations reveal that the majority of dental hygiene educators have positive opinions regarding the use of behavioral strategies for managing client anxiety during dental hygiene care. However, only 28 percent of faculty have received instruction in this area. Results suggest that comprehensive instruction on behavioral strategies for managing client anxiety is not afforded to students in all dental hygiene programs, even though dental hygiene educators consider these strategies effective during oral healthcare.

description: Global navigation satellite systems have revolutionized the way people are navigating vehicles in unknown environments, and improved the driving experience in complex traffic areas. Satellite based navigation systems however experience their limitations in densely developed areas with high buildings, as satellite signals get attenuated, blocked and reflected by objects in the line of sight between the user and the satellite. Unfortunately, areas with degraded satellite conditions correlate well with areas of more complex navigation requirements, leading to less reliable navigation capabilities where it is needed most. Current in-dash navigation systems integrate additional sensors such as inertial and wheel sensors, with the drawback of vehicle-specific, inaccurate and often biased measurements. With the recent introduction of advanced driver assistance systems, optical systems become attractive additional sensors. Although cost-effective visible light cameras can provide useful measurements, their usage in combination with satellite navigation systems has not attracted much interest up to this date. This research reached the goal of accurate navigation in urban environments by deeply integrating vision sensors with satellite navigation systems, while intentionally omitting inertial sensors. The proposed system was tailored specifically for road vehicles, where the test vehicle was post-equipped with a stereo camera and a custom multi-constellation satellite navigation receiver. The error characteristics of the visual sensor system were simulated in software and tested in a laboratory environment. Furthermore, extensive testing in challenging environments was performed, which shows the advantages and limitations of the proposed system in real environments. The navigation performance of different GNSS only, GNSS/INS and GNSS/vision implementations was compared. The GNSS/vision system provided a continuously available navigation solution, and despite the fact that the used IMU was of cost-intensive tactical grade, the integrated GNSS/vision system consistently outperformed all other systems.

description: We present the results from an ultra-high-resolution 7mm Very Long Baseline Array (VLBA) study of the relativistic jet in the BL Lacertae object OJ287 from 1995 to 2011 containing 136 total intensity images. Analysis of the image sequence reveals a sharp jet-position-angle swing by >100 deg. during [2004,2006], as viewed in the plane of the sky, that we interpret as the crossing of the jet from one side of the line of sight to the other during a softer and longer term swing of the inner jet. Modulating such long term swing, our images also show for the first time a prominent erratic wobbling behavior of the innermost ~0.4mas of the jet with fluctuations in position angle of up to ~40 deg. over time scales ~2yr. This is accompanied by highly superluminal motions along non-radial trajectories, which reflect the remarkable non-ballistic nature of the jet plasma on these scales. The erratic nature and short time scales of the observed behavior rules out scenarios such as binary black hole systems, accretion disk precession, and interaction with the ambient medium as possible origins of the phenomenon on the scales probed by our observations, although such processes may cause longer-term modulation of the jet direction. We propose that variable asymmetric injection of the jet flow; perhaps related to turbulence in the accretion disk; coupled with hydrodynamic instabilities, leads to the non-ballistic dynamics that cause the observed non-periodic changes in the direction of the inner jet.

Particular emphasis is laid on structural differences, which may allow to identify a star's nature and evolutionary phase in spite of the fact that it is found in a region of the Hertzsprung-Russell-Diagram objects from both mass ranges may populate. Seismic diagnostics which are sensitive to the temperature and density profile at the border of the helium core and outside of it may be the most promising tool.

description: Digital Communications play an important role in modern worlds, and it is crucial to consider the security problems associated with network communication. This dissertation explores the use of physical layer characteristics of communication channels and network multipath to build secure and reliable communication in adversarial setting. We investigate four ad- versarial models: limited view adversary channel, adversarial wiretap channel, adversarial wiretap channel with public discussion, and Secure Message Transmission. The first three models are about secure communication using physical layer characters, and the last is about using network multipath for communication. We first consider secure and reliable communication over a wiretap channel with an active adversary. We consider on adversarial channel model, in which the adversary is able to eavesdrop the communication between the sender and the receiver, and also corrupt the communication by adding adversarial noise. The model of limited view adversary focuses on reliable communication over this channel, and the construction of limited view adversary code achieves reliable communication in this setting. Adversarial wiretap channel studies secure and reliable transmission over this adversarial channel. We obtain an upper bound on the capacity of this channel, and construct an adversarial wiretap code that provides secure and reliable communication over this channel. By allowing communicants to have access to a public discussion channel, secure communication becomes possible over adversarial wiretap channel for a wider range of parameters. We then consider on Secure Message Transmission in networks. We propose a new construction for secure message transmission protocols using a list decodable code and a message authentication code. Our protocol has optimal transmission rate and provides the highest reliability among all known comparable protocols.

description: Context. Ultracompact X-ray binaries (UCXBs) typically consist of a white dwarf donor and a neutron star or black hole accretor. The evolution of UCXBs and very low mass ratio binaries in general is poorly understood. Aims. We investigate the evolution of UCXBs in order to learn for which mass ratios and accretor types these systems can exist, and if they do, what are their orbital and neutron star spin periods, mass transfer rates and evolutionary timescales. Methods. For different assumptions concerning accretion disk behavior we calculate for which system parameters dynamical instability, thermal-viscous disk instability or the propeller effect emerge. Results. At the onset of mass transfer, the survival of the UCXB is determined by how efficiently the accretor can eject matter in the case of a super-Eddington mass transfer rate. At later times, the evolution of systems strongly depends on the binary's capacity to return angular momentum from the disk to the orbit. We find that this feedback mechanism most likely remains effective. In the case of steady mass transfer, the propeller effect can stop accretion onto recycled neutron stars completely at a sufficiently low mass transfer rate, based on energy considerations. However, mass transfer will likely be non-steady because disk instability allows for accretion of some of the transferred matter. Together, the propeller effect and disk instability cause the low mass ratio UCXBs to be visible a small fraction of the time at most, thereby explaining the lack of observations of such systems. Conclusions. Most likely UCXBs avoid late-time dynamically unstable mass transfer and continue to evolve as the age of the Universe allows. This implies the existence of a large population of low mass ratio binaries with orbital periods ~ 70 - 80 min, unless some other mechanism has destroyed these binaries.

description: The Isabelle/PIDE platform addresses the question whether proof assistants of the LCF family are suitable as technological basis for educational tools. The traditionally strong logical foundations of systems like HOL, Coq, or Isabelle have so far been counter-balanced by somewhat inaccessible interaction via the TTY (or minor variations like the well-known Proof General / Emacs interface). Thus the fundamental question of math education tools with fully-formal background theories has often been answered negatively due to accidental weaknesses of existing proof engines. The idea of "PIDE" (which means "Prover IDE") is to integrate existing provers like Isabelle into a larger environment, that facilitates access by end-users and other tools. We use Scala to expose the proof engine in ML to the JVM world, where many user-interfaces, editor frameworks, and educational tools already exist. This shall ultimately lead to combined mathematical assistants, where the logical engine is in the background, without obstructing the view on applications of formal methods, formalized mathematics, and math education in particular.

description: When performing radio detection of ultra-high energy astroparticles, the planar wavefront model is often used as a first step to evaluate the arrival direction of primary particles. This model estimates the direction by adjusting the wavefront orientation based on the peak timing of the signal traces from individual antennas. However, despite it's simplicity, the usefulness of this approach is limited by the lack of a good assessment of its robustness and the lack of confidence in its performance. To address these limitations, this study presents two analytical methods to solve for the planar wavefront arrival direction. In addition, we provide the corresponding analytical reconstruction uncertainty, offering a more a more detailed evaluation of the reconstruction's reliability.

description: This narrative research study explores the adult learning journey of teachers who teach about Islam in Alberta public schools. It tells stories of their experiences that are informed by personal convictions and sociocultural surroundings. The study focuses intentionally on how perceptions of Islam held by teachers change, if at all. It also directs attention to the impact of teaching and learning about Islam on teacher religious and nonreligious identities. Four teacher participants, from different schools, were invited to share their stories and experiences teaching about Islam in the World Religions course. Narrative inquiry proved to be an invaluable guide in discovering and interpreting teacher learning journeys. Participants brought forth various understandings of Islam and diverse religious and nonreligious identities to the classroom space. Teaching about Islam resulted in strengthened religious and nonreligious convictions, and influenced in an important way, the nature of changes in perceptions of Islam teacher participants developed. While the field of adult education is increasingly attending to the multidimensional ways that adults learn and change, the contribution of one’s religious convictions in interreligious learning has not been extensively explored. As well, this study suggests that teachers and students actively engage with diverse religious and nonreligious outlooks and lived experiences in order to support deep learning. Thus, while it explores teacher experiences and changes, this dissertation also aims to articulate a way forward in curriculum and teacher development. As we increasingly encounter diverse and fellow human beings, this study highlights the great importance of learning about each other, from each other.

In contrast to Krakoviack's theory, our approach predicts a random pinning glass transition scenario that is qualitatively the same as the scenario obtained using a mean-field analysis of the spherical p-spin model and a mean-field version of the random first-order transition theory. We use our approach to calculate quantities which are often considered to be indicators of growing dynamic correlations and static point-to-set correlations. We find that the so-called static overlap is dominated by the simple, low pinning fraction contribution. Thus, at least for randomly pinned fluid systems, only a careful quantitative analysis of simulation results can reveal genuine, many-body point-to-set correlations.

description: The formation, composition and physical properties of lunar dust are incompletely characterised with regard to human health. While the physical and chemical determinants of dust toxicity for materials such as asbestos, quartz, volcanic ashes and urban particulate matter have been the focus of substantial research efforts, lunar dust properties, and therefore lunar dust toxicity may differ substantially. In this contribution, past and ongoing work on dust toxicity is reviewed, and major knowledge gaps that prevent an accurate assessment of lunar dust toxicity are identified. Finally, a range of studies using ground-based, low-gravity, and in situ measurements is recommended to address the identified knowledge gaps. Because none of the curated lunar samples exist in a pristine state that preserves the surface reactive chemical aspects thought to be present on the lunar surface, studies using this material carry with them considerable uncertainty in terms of fidelity. As a consequence, in situ data on lunar dust properties will be required to provide ground truth for ground-based studies quantifying the toxicity of dust exposure and the associated health risks during future manned lunar missions.

description: Quaternary Legendre pairs are pertinent to the construction of quaternary Hadamard matrices and have many applications, for example in coding theory and communications. In contrast to binary Legendre pairs, quaternary ones can exist for even length $\ell$ as well. It is conjectured that there is a quaternary Legendre pair for any even $\ell$. The smallest open case until now had been $\ell=28$, and $\ell=38$ was the only length $\ell$ with $28\le \ell\le 60$ resolved before. Here we provide constructions for $\ell=28,30,32$, and $34$. In parallel and independently, Jedwab and Pender found a construction of quaternary Legendre pairs of length $\ell=(q-1)/2$ for any prime power $q\equiv 1\bmod 4$, which in particular covers $\ell=30$, $36$, and $40$, so that now $\ell=42$ is the smallest unresolved case. The main new idea of this paper is a way to separate the search for the subsequences along even and odd indices which substantially reduces the complexity of the search algorithm. In addition, we use Galois theory for cyclotomic fields to derive conditions which improve the PSD test.

description: The presence of magnetic clusters has been verified in both antiferromagnetic and ferromagnetic quantum critical systems. We review some of the strongest evidence for strongly doped quantum critical systems (Ce(Ru$_{0.24}$Fe$_{0.76}$)$_2$Ge$_2$) and we discuss the implications for the response of the system when cluster formation is combined with finite size effects. In particular, we discuss the change of universality class that is observed close to the order-disorder transition. We detail the conditions under which clustering effects will play a significant role also in the response of stoichiometric systems and their experimental signature.

description: The proliferation of e-commerce and urbanization has significantly intensified delivery operations in urban areas, boosting the volume and complexity of delivery demand. Data-driven predictive methods, especially those utilizing machine learning techniques, have emerged to handle these complexities in urban delivery demand management problems. One particularly pressing issue that has yet to be sufficiently addressed is the joint estimation and prediction of city-wide delivery demand, as well as the generalization of the model to new cities. To this end, we formulate this problem as a transferable graph-based spatiotemporal learning task. First, an individual-collective message-passing neural network model is formalized to capture the interaction between demand patterns of associated regions. Second, by exploiting recent advances in large language models (LLMs), we extract general geospatial knowledge encodings from the unstructured locational data using the embedding generated by LLMs. Last, to encourage the cross-city generalization of the model, we integrate the encoding into the demand predictor in a transferable way. Comprehensive empirical evaluation results on two real-world delivery datasets, including eight cities in China and the US, demonstrate that our model significantly outperforms state-of-the-art baselines in accuracy, efficiency, and transferability.
Derivation of the NLS breather solutions using displaced phase-amplitude variables

description: Breather solutions of the nonlinear Schrödinger equation are derived in this paper: the Soliton on Finite Background, the Ma breather and the rational breather. A special Ansatz of a displaced phase-amplitude equation with respect to a background is used as has been proposed by van Groesen et. al. (2006). Requiring the displaced phase to be temporally independent, has as consequence that the dynamics at each position is described by the motion of a nonlinear autonomous oscillator in a potential energy that depends on the phase and on the spatial phase change. The relation among the breather solutions is confirmed by explicit expressions, and illustrated with the amplitude amplification factor. Additionally, the corresponding physical wave field is also studied and wavefront dislocation together with phase singularity at vanishing amplitude are observed in all three cases.

description: Small-scale integrated (SSI) farming is a common agricultural model in Vietnam. However, SSI farmers use contaminated water, have no access to hygienic latrines, and have very limited awareness about water quality or environmental sanitation. There are potential interactions in the context of this model that may result in transmission of water-related zoonotic diseases (WRZD). The government of Vietnam plans to restructure the agriculture system by 2020. Study of the model in the context of water and public health can contribute to shaping the future of Vietnam’s agriculture system. I used a cross-sectional study to develop a socioeconomic profile of SSI farmers, examine their perceptions of risk factors for transmitting WRZD, assess basic microbial and related quality of water used on their farms, and explore factors that are associated with on-farm water quality as well as SSI farmers’ engagement in strategies to reduce transmission of WRZD. Data were collected from 600 SSI farms in two provinces in North and South Vietnam. The typical profile of the participating SSI farmers was a 45 year old married individual with two children, seven years of formal education, low income (c. $1200 p.a.), and nine years farming experience. Most SSI farmers had basic awareness of avian influenza prevention, but very limited awareness of WRZDs such as Escherichia coli (E. coli). Water on the majority of SSI farms had unacceptable levels of E. coli and was significantly associated with SSI farmers’ characteristics and perceptions (e.g., years of farming, number of poultry on a farm, and perceived self-efficacy in managing livestock). SSI farmers’ characteristics and perceptions (e.g., education, income, and perceived self-efficacy in managing livestock) influenced their engagement in strategies to reduce transmission of WRZD. Future research and policies in Vietnamese agriculture need to consider a transdisciplinary approach (e.g., EcoHealth) to increase SSI farmers’ awareness of water public health and their engagement in mitigating strategies for WRZD transmission. Consideration for the health of farmers, animals, and the environment should be interwoven with livestock production and be an equally important part of a holistic integrated SSI farming model.
Enhanced anisotropic spin fluctuations below tetragonal-to-orthorhombic transition in LaFeAs(O_{1-x}F_x) probed by ^{75}As and ^{139}La NMR

description: $^{75}$As and $^{139}$La NMR results of LaFeAs(O$_{1-x}$F$_x$) ($x$=0, 0.025, and 0.04) were reported. Upon F-doping, the tetragonal-to-orthorhombic structural phase transition temperature $T_S$, antiferromagnetic transition temperature $T_N$ and internal magnetic field $μ_0H_{\rm int}$ are gradually reduced for $x<0.04$. However, at $x=0.04$, $T_N$ is abruptly suppressed to be 30 K along with a tiny $μ_0H_{\rm int}$, which is distinct from the continuous disappearance of the ordered phases in the Ba122 systems of Ba(Fe,Co)$_2$As$_2$ and BaFe$_2$(As,P)$_2$. The anisotropy of the spin-lattice relaxation rate $T_1^{-1}$, $(T_1)^{-1}_{H\parallel ab}/(T_1)^{-1}_{H\parallel c}$, in the paramagnetic phase of $x = 0$ and 0.025 is constant ($\sim 1.5$), but increases abruptly below $T_S$ due to the enhancement of $(T_1)^{-1}_{H\parallel ab}$ by the slowing down of magnetic fluctuations. This indicates that the tetragonal-to-orthorhombic structural distortion enhances the anisotropy in the spin space via magnetoelastic coupling and/or spin-orbit interaction.
