The modulatory role of selective attention on p50 sensory gating and event related beta activity in schizophrenia
Creators: name: Rumak, Samuel Peter
Publisher: name: University of British Columbia
Year: 2011

description: Sensory gating refers the central nervous system’s capacity to filter redundant sensory information. Deficient auditory sensory gating abilities have been documented in individuals with schizophrenia and may contribute to some of the sensory and perceptual disturbances associated with this disorder. When using event-related potentials (ERP) to investigate the phenomenon of sensory gating, traditional dual-click paradigms focus on the attenuation in P50 amplitude to the second click (S2) compared to the first click (S1). While long believed to be pre-attentional, recent findings have suggested that this phenomenon can be modulated by selective attention. A standard dual-click task and two modified dual-click tasks that required participants to attend to either S1 or S2 were used to examine the effect of selective attention on S1 or S2 P50 amplitude in (n=25) participants with schizophrenia and (n=24) healthy controls. Results reveal that attending to S1 increases P50 amplitude to S1 for healthy controls but not for the schizophrenia group. There were no increases to S2 P50 amplitude for either group when attending to S2. Subsequently there were also no differences for either group to the S1-S2 difference scores when attending to S1 or S2. Wavelet analysis of event-related Beta-1 frequency activity revealed that controls were able to augment their Beta-1 response to S1 when attending to S1 but not their Beta-1 response to S2-when attending to S2. The schizophrenia group did not show increased Beta-1 activity when attending to S1 but did show increased Beta-1 activity to S2 when attending to S1 and when attending to S2. The different pattern of Beta-1 activity in controls and individuals with schizophrenia might reflect an underlying deficiency that individuals with schizophrenia have in processing salient auditory information. Furthermore, these results are consistent within the context of selective attention deficiencies that are commonly reported in individuals with schizophrenia.

description: 4-(Dimethylamino)-1-((4-nitrophenyl)sulfonyl)pyridin-1-ium chloride ([DMAPNS]+Cl−) has been designed based on DFT studies to have higher reactivity coupled with better stability than that of [DMAPTS]+Cl−. Accordingly, this novel reagent was prepared by using 1.0 equivalent of p-nitrobenzene sulfonyl chloride (1), 1.0 equivalent of DMAP (2) with higher yield (>99%), using sustainable approaches. The following greener techniques were optimized in the preparation of the novel reagent (i) less hazardous method (3rd principle of green chemistry), (ii) bio renewable (7th principle of green chemistry), 2-MeTHF solvent (Class 3 solvent), (iii) room temperature (6th principle of green chemistry), and (iv) column chromatography free methods (4th principle of green chemistry).
Forum theatre, technology and desire : an investigation of Headlines Theatre's online broadcasts

Publisher: name: University of British Columbia
Year: 2011

description: This thesis investigates Headlines Theatre Company’s use of simulcast online video broadcasts of their forum theatre events through two case studies, Here and Now (2005) and after homelessness... (2009). I consider the place of these broadcast’s within Headlines’ Artistic Director David Diamond’s particular practice, Theatre for Living (TfL) and its aim to create community-based dialogue. Through digital performance theorist Steve Dixon’s four categories of interactivity, I explore how the online viewer’s participation in the forum event is filtered via the use of web-actors, and the complications this has had for the broader TfL mandate. I analyse the web-actors’ function using Dixon’s concept of “The Digital Double”, to explore how the role they have in the forum event is akin to that of avatars. This analysis draws primarily from David Diamond’s published works, personal journals and reports following each production as well as recorded broadcasts of the two case-study performances. Read together with current scholarship of performance and digital technology, I argue that these case studies suggest how technology both has and has not served the TfL mandate and consider how Headlines’ practice is complicated by simulcast online video broadcasts.

description: In this work, we describe a novel, easy and green method for the synthesis of diazaphosphinine derivatives. The new diazaphosphinines were prepared by condensation of phosphorus oxychloride with the corresponding benzamides under reflux in acetone with moderate to good yields. The structures of the new compounds were confirmed on the basis of their infrared and nuclear magnetic resonance spectral data (1H, 13C, and 31P), MS, and elemental analysis.

description: This paper identifies issues for language generation that arose in developing a multimedia interface to healthcare data that includes coordinated speech, text and graphics. In order to produce brief speech for time-pressured caregivers, the system both combines related information into a single sentence and uses abbreviated references in speech when an unambiguous textual reference is also used. Finally, due to the temporal nature of the speech, the language generation module needs to communicate informa- tion about the ordering and duration of references to other temporal media, such as graphics, in order to allow for coordination between media.

description: The electronic properties of single and few-particles in core-shell nanowire quantum dots (NWQD) are investigated. By performing configuration interaction (CI) calculations we particularly elucidate how elevated symmetry character (C3v or D2d) exhibited by single particle orbitals enhances the phase coherence of exciton-photon wavefunction though suppressing spin flip processes. Detailed calculations presented here demonstrate how strain-induced potentials manipulate the symmetry characters, intrinsic oscillator strength and electron-hole dipole in NWQDs. An orbital-dependent kinetic energy is defined based on single particle dispersion and orbital spreadout in k-space. It is shown the exchange occurring between this kinetic energy and strain-induced potentials is responsible for orbital distortions, and thus the energy reordering of different direct and correlation terms. Various structures have been examined to elaborate on the influence of size and orientation together with axial and lateral symmetry of NWQDs. Our many-body calculations suggest that binding energies of s-shell few particle resonances XX0 and trions are suppressed when axial and lateral localizations become comparable. Then exerting an external perturbation may renormalize the binding energies, realizing a transition from anti-binding to binding regime or reverse. In this regard, we specifically show that kinetic energy of single particles, and thus correlation energies of associated complexes, exposed to an electric field remain relatively unaffected and the interplay between direct Coulomb terms reorders the multiexcitonic resonances. Sub-micro-eV fine structure splitting along with the tunable XX0 binding energy offers NWQDs promising for generating entangled photons in both regular and time reordering schemes.

description: In empirical studies of friendship networks participants are typically asked, in interviews or questionnaires, to identify some or all of their close friends, resulting in a directed network in which friendships can, and often do, run in only one direction between a pair of individuals. Here we analyze a large collection of such networks representing friendships among students at US high and junior-high schools and show that the pattern of unreciprocated friendships is far from random. In every network, without exception, we find that there exists a ranking of participants, from low to high, such that almost all unreciprocated friendships consist of a lower-ranked individual claiming friendship with a higher-ranked one. We present a maximum-likelihood method for deducing such rankings from observed network data and conjecture that the rankings produced reflect a measure of social status. We note in particular that reciprocated and unreciprocated friendships obey different statistics, suggesting different formation processes, and that rankings are correlated with other characteristics of the participants that are traditionally associated with status, such as age and overall popularity as measured by total number of friends.

Noncommutative Complex Scalar Field and Casimir Effect

description: A noncommutative complex scalar field, satisfying the deformed canonical commutation relations proposed by Carmona et al. [27]-[31], is constructed. Using these noncommutative deformed canonical commutation relations, a model describing the dynamics of the noncommutative complex scalar field is proposed. The noncommutative field equations are solved, and the vacuum energy is calculated to the second order in the parameter of noncommutativity. As an application to this model, the Casimir effect, due to the zero point fluctuations of the noncommutative complex scalar field, is considered. It turns out that in spite of its smallness, the noncommutativity gives rise to a repulsive force at the microscopic level, leading to a modifed Casimr potential with a minimum at the point amin= racine(5/84)πθ.

description: A lexicon is an essential component in a generation system but few efforts have been made to build a rich, large-scale lexicon and make it reusable for different generation applications. In this paper, we describe our work to build such a lexicon by combining multiple, heterogeneous linguistic resources which have been developed for other purposes. Novel transformation and integration of resources is required to reuse them for generation. We also applied the lexicon to the lexical choice and realization component of a practical generation application by using a multi-level feedback architecture. The integration of the lexicon and the architecture is able to effectively improve the system paraphrasing power, minimize the chance of grammatical errors, and simplify the development process substantially.

Labor market

description: Over the past few years, a multitude of studies have examined the labor market returns to community college credentials, taking advantage of new administrative datasets that link college transcripts to quarterly earnings records and allow for comparisons of students’ earnings before and after enrollment. These studies, however, typically follow students for only four to six years after initial entry, meaning they may only be observed for a year or two after graduation. Graduates’ early labor market experiences may not fully capture the returns to completion, and may particularly distort comparisons of longer versus shorter duration credential programs. This paper extends the literature by examining returns to terminal associate degrees and certificates up to 11 years after students initially entered a community college in Ohio. The authors use an individual fixed-effects approach that controls for students’ pre-enrollment earnings and allows the returns to credential completion to vary over time. Additionally, they examine how the returns to credential completion shift as students enter and exit the Great Recession, as well as how credentials affect other labor market outcomes such as employment stability and the likelihood of earning a “living wage.” The authors’ results confirm prior findings regarding the positive early returns to associate degrees and long-term certificates. However, the value of an associate degree grows substantially after graduation while the returns to a long-term certificate remain flat. Returns to associate degrees are notably higher during the recession (the patterns for certificates are more muted and vary by gender). Finally, the authors find that while both associate degrees and long-term certificates increase the likelihood and stability of employment, associate degrees lead to much higher paying jobs and a greater likelihood of earning a living wage. The authors conclude with a discussion of policy implications.

The chemical formula of the samples was determined as NaY (Na0.91AlSi2.31O11), NiNaY (Ni0.64Na0.15AlSi2.3O11), and MnNaY (Mn0.5Na0.15AlSi2.3O11) using the EDS analysis. The prepared catalyst has suitable potential for the oxidation of sulfides to sulfoxides under mild conditions and was reused 11 times without significant losses in its potential and catalytic activity.

description: By synthesizing information common to retrieved documents, multi-document summarization can help users of information retrieval systems to find relevant documents with a minimal amount of reading. We are developing a multidocument summarization system to automatically generate a concise summary by identifying and synthesizing similarities across a set of related documents. Our approach is unique in its integration of machine learning and statistical techniques to identify similar paragraphs, intersection of similar phrases within paragraphs, and language generation to reformulate the wording of the summary. Our evaluation of system components shows that learning over multiple extracted linguistic features is more effective than information retrieval approaches at identifying similar text units for summarization and that it is possible to generate a fluent summary that conveys similarities among documents even when full semantic interpretations of the input text are not available.

description: High levels of lead (Pb) in the soil is a serious issue in the city of Kabwe, Zambia. Phytoremediation is an effective approach to revive the life-supporting functions of the soils. Locally available soil amendments, such as chicken manure, can strengthen phytoremediation. This study aims to find an appropriate combination of a locally available Pb hyperaccumulator, lemongrass (Cymbopogon citratus (DC.) Stapf.), and soil amendments, to minimize the Pb pollution. After a short-term (78 day) pot experiment with lemongrass and three soil amendments (chicken manure, biochar of chicken manure, and urea) on a Pb-contaminated soil in Kabwe, an edible crop, dent corn (Zea mays var. indentata (Sturtev.) L.H.Bailey), was grown for two weeks. Chicken manure combined with lemongrass had the most beneficial impact, reducing the Pb level in dent corn by 19%, compared to the Pb in dent corn grown on the control soil. By growing lemongrass in the Kabwe soil with chicken manure, the exchangeable soil Pb was reduced by 70%. The growth of lemongrass without chicken manure reduced the exchangeable soil Pb by 20%. In conclusion, lemongrass successfully reduced Pb levels, in combination with chicken manure. Soil amendments must be chosen carefully by considering the soil properties and environmental conditions for an optimized Pb reduction.

description: This study reports a facile mechanochemical conversion of N-phenylthiosemicarbazone derivatives of 1-tetralone analogs into thiazolidin-4-ones, thiazolidin-5-ylidene-acetates, and dihydrothiazoles by their condensation with chloroacetic acid, DMAD, and phenacyl bromide, respectively. Triethylammonium hydrogen sulfate [Et3NH]+ [HSO4]− is employed as solid catalyst for this prompt and ecological conversion through which the target products are formed within 10–30 minutes in quantitative yields. The products have been characterized on the basis of spectroscopic data. X-ray diffraction studies of thiazolidin-5-ylidene-acetate 5b, supported by DFT calculations of E/Z isomers of 5b, are presented. Compounds 4, 5, and 7 are assayed for their antibacterial prospects against Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative) bacterial stains. Some derivatives show highly promising antibacterial activities.

description: We discuss the Hawking temperature of near-equilibrium black holes using a semiclassical analysis. We introduce a useful expansion method for slowly evolving spacetime, and evaluate the Bogoliubov coefficients using the saddle point approximation. For a spacetime whose evolution is sufficiently slow, such as a black hole with slowly changing mass, we find that the temperature is determined by the surface gravity of the past horizon. As an example of applications of these results, we study the Hawking temperature of black holes with null shell accretion in asymptotically flat space and the AdS-Vaidya spacetime. We discuss implications of our results in the context of the AdS/CFT correspondence.

description: The electronic properties of graphene can be manipulated via mechanical deformations, which opens prospects for studying the Dirac fermions in new regimes and for new device applications. Certain natural configurations of strain generate large nearly uniform pseudo-magnetic fields, which have opposite signs in the two valleys, and give rise to flat spin- and valley-degenerate pseudo Landau levels (PLLs). Here we consider the effect of the Coulomb interactions in strained graphene with uniform pseudo-magnetic field. We show that the spin/valley degeneracies of the PLLs get lifted by the interactions, giving rise to topological insulator-like states. In particular, when a nonzero PLL is quarter- or three-quarter filled, an anomalous quantum Hall state spontaneously breaking time-reversal symmetry emerges. At half-filled PLL, weak spin-orbital interaction stabilizes time-reversal-symmetric quantum spin-Hall state. These many-body states are characterized by the quantized conductance and persist to a high temperature scale set by the Coulomb interactions, which we estimate to be a few hundreds Kelvin at moderate strain values. At fractional fillings, fractional quantum Hall states breaking valley symmetry emerge. These results suggest a new route to realizing robust topological insulator states in mesoscopic graphene.

description: Thirty-five novel 1,3,4-thiadiazole-S-alkyl derivatives based on quinazolinone have been designed and synthesized. The structures of the target compounds 5a − 5p and 6a − 6s were confirmed by their IR, 1H NMR, 13C NMR, HR-ESI-MS spectroscopic data. This study detected their cytotoxicity for mouse fibroblast (normal cells, L929) and their in vitro antiproliferative activities against human cancer cell lines (Hela, MCF-7 and A549) by using CCK-8 assay. The results of all the tested compounds 5a − 5p and 6a − 6s showed that the growth and reproduction of cells were impeded to a certain extent. Compared with the reference drug 5-FU, some compounds even showed better proliferation inhibition against various cancer cells. Among these, most of the compounds had relatively less cytotoxicity to L929 cells. 6-Chloro-2-(2-(benzylthio)-1,3,4-thiadiazol-5-yl)-quinazolin-4(3H)-one (6a) gave expression to the strongest inhibitory activity on Hela cells with IC50 value of 1.40 µM. 6-Chloro-2-[2-(4-trifluoromethylbenzylthio)-1,3,4-thiadiazol-5-yl]-quinazolin-4(3H)-one (6s) displayed high antitumor activities against MCF-7 cells with IC50 values of 3.01 µM. 2-[2-(Benzylthio)-1,3,4-thiadiazol-5-yl]-quinazolin-4(3H)-one (5a) revealed excellent antitumor activities against A549 cells with IC50 values of 2.21 µM.

description: Annotating photographs automatically with content descriptions facilitates organization, storage, and search over visual information. We present an integrated approach for scene classification that combines image-based and text-based approaches. On the text side, we use the text accompanying an image in a novel TF*IDF vector-based approach to classification. On the image side, we present a novel OF*IIF (object frequency) vector-based approach to classification. Objects are defined by clustering of segmented regions of training images. The image based OF*IIF approach is synergistic with the text based TF*IDF approach. By integrating the TF*IDF approach and the OF*IIF approach, we achieved a classification accuracy of 86%. This is an improvement of approximately 12% over existing image classifiers, an improvement of approximately 3% over the TF*IDF image classifier based on textual information, and an improvement of approximately 4% over the OF*IIF image classifier based on visual information.
Awareness of cue utility is important in producing the proportion valid effect, but conscious awareness is not
Creators: name: Lanthier, Sophie Nicole
Publisher: name: University of British Columbia
Year: 2011

description: The present experiments investigated the mechanism responsible for the proportion valid cueing effect (i.e., the difference in response times between valid and invalid trials increases in magnitude as the proportion of valid trials increases) in the covert orienting paradigm. This proportion validity effect (PVE) is believed to reflect the involvement of volitional control of visual attention. However, more recently research has suggested that the PVE reflects a form of implicit learning (i.e., wherein associations, developed outside of awareness, between the cue and target location determine how attention is distributed, Seger, 1994). I tested between these two accounts of the PVE by determining whether being aware of a cue’s spatial utility influences the PVE using peripheral box cues (Experiment 1), central arrow cues (Experiment 2) and central non-directional shapes (i.e., cues that do not possess inherent directionality, Experiment 3). Critically, I manipulated whether participants were aware of the cue-target relations and determined whether this awareness influenced the PVE. Peripheral box cues produced a PVE that was independent and insensitive to participants' awareness of cue-target relations. On the other hand, central cues (i.e., both arrow cues and non-directional cues) produced PVEs that were sensitive to our manipulation of awareness regarding cue-target relations. However, central arrow cues produced a PVE that was independent of awareness, whereas non-directional cues produced a PVE that was dependent on awareness of cue-target relations. Taken together, the present studies have demonstrated that the awareness of the association between cues and target locations does contribute, under some circumstances, to the PVE. However, the extent to which the PVE is influenced by awareness of cue-target relations is dependent on the type of cue used to orient attention.

description: Fluids often display dissipative properties. We explore dissipation in the form of bulk viscosity in the cold dark matter fluid. We constrain this model using current data from supernovae, baryon acoustic oscillations and the cosmic microwave background. Considering the isotropic and homogeneous background only, viscous dark matter is allowed to have a bulk viscosity $\lesssim 10^7$ Pa$\cdot$s, also consistent with the expected integrated Sachs-Wolfe effect (which plagues some models with bulk viscosity). We further investigate the small-scale formation of viscous dark matter halos, which turns out to place significantly stronger constraints on the dark matter viscosity. The existence of dwarf galaxies is guaranteed only for much smaller values of the dark matter viscosity, $\lesssim 10^{-3}$ Pa$\cdot$s.

description: Two methods are used for evaluation of summarization systems: an evaluation of generated summaries against an "ideal" summary and evaluation of how well summaries help a person perform in a task such as information retrieval. We carried out two large experiments to study the two evaluation methods. Our results show that different parameters of an experiment can dramatically affect how well a system scores. For example, summary length was found to affect both types of evaluations. For the "ideal" summary based evaluation, accuracy decreases as summary length increases, while for task based evaluations summary length and accuracy on an information retrieval task appear to correlate randomly. In this paper, we show how this parameter and others can affect evaluation results and describe how parameters can be controlled to produce a sound evaluation.

description: We describe a method for identifying the speakers of quoted speech in natural-language textual stories. We have assembled a corpus of more than 3,000 quotations, whose speakers (if any) are manually identiﬁed, from a collection of 19th and 20th century literature by six authors. Using rule-based and statistical learning, our method identiﬁes candidate characters, determines their genders, and attributes each quote to the most likely speaker. We divide the quotes into syntactic classes in
order to leverage common discourse patterns, which enable rapid attribution for many quotes. We apply learning algorithms to the remainder and achieve an overall accuracy of 83%.

description: A practical goal for natural language text generation research is to converge on a separation of functions into modules that can be independently re-used. This paper addresses issues related to software re-use and evolution in text generation systems. We describe the benefits we obtained by adapting and generalizing the generation modules and techniques we used for the successive development of three distinct text generation applications, PLANDoc, FlowDoc, and ZEDDoc. We suggest that design principles such as the use of a common, modular pipeline architecture, a consistent and general data representation format, and domain-independent algorithms for generation subtasks, together with component re-use and adaptation, facilitate both application development and research in the field. In our experience, these principles led to significant reductions in development time for successive applications, from three years to one year to six months, respectively. They also enabled us to isolate domain-specific knowledge and devise reusable, domain-independent algorithms for generation tasks such as ontological generalization and discourse structuring.

description: We present a domain-independent topic segmentation algorithm for multi-party speech. Our feature-based algorithm combines knowledge about content using a text-based algorithm as a feature and about form using linguistic and acoustic cues about topic shifts extracted from speech. This segmentation algorithm uses automatically induced decision rules to combine the different features. The embedded text-based algorithm builds on lexical cohesion and has performance comparable to state-of-the-art algorithms based on lexical information. A significant error reduction is obtained by combining the two knowledge sources.

description: We introduce a new implementation of the FastICA algorithm on simulated LOFAR EoR data with the aim of accurately removing the foregrounds and extracting the 21-cm reionization signal. We find that the method successfully removes the foregrounds with an average fitting error of 0.5 per cent and that the 2D and 3D power spectra are recovered across the frequency range. We find that for scales above several PSF scales the 21-cm variance is successfully recovered though there is evidence of noise leakage into the reconstructed foreground components. We find that this blind independent component analysis technique provides encouraging results without the danger of prior foreground assumptions.

description: We report on an evaluation of MAGIC, a system that automatically generates briefings of patient status after coronary bypass surgery, completed in the Cardio Thoracic Intensive Care Unit at New York Presbyterian Hospital. Through enhancements in system design, robustness and speed, we compared information obtained by nurses against two briefings, one automatically generated by MAGIC and one provided by physicians upon the patient's arrival to the ICU. Our results show that MAGIC and the physician briefing provide a substantial increase in the amount of information than is available prior to the patient's arrival and that the information MAGIC provides is accurate. In many aspects, MAGIC out-performs the physician briefing; information is reported earlier and is always available. We conclude that MAGIC provides the CT ICU staff early on with a better assessment of the patient's status than in current practice and allows them to better prepare for the patient's arrival.
Intensive Betreuungsmaßnahmen als komplexe Interventionen in der stationären psychiatrischen Versorgung : [kumulative Dissertation]

description: Intensive Betreuungsmaßnahmen werden in akutpsychiatrischen Notfallsituationen in der stationären psychiatrischen Behandlung eingesetzt. Verschiedene Methoden wurden zur Erforschung des Ansatzes angewendet. Zunächst werden die Ergebnisse einer systematischen Literaturrecherche zu Intensivmaßnahmen vorgestellt. Weiterhin wurden Sekundärdaten ausgewertet, um die Bedeutung des Themas in der psychiatrischen Versorgung darzustellen. Schließlich wurde das Thema der Intensivbetreuung in einen breiteren Kontext gestellt und in einer multizentrischen Studie betrachtet. Die Ergebnisse zeigen, dass intensive Betreuungsmaßnahmen komplexe Interventionen sind, da sie eine Vielzahl interagierender Komponenten kombinieren. Die Anwendung der Maßnahmen erfolgt sehr unterschiedlich. Quantitative Aspekte der Besetzung und der Rahmenbedingungen scheinen Einfluss auf das Auftreten von Konflikten und Eindämmungsmaßnahmen und damit auf die Anwendung von intensiven Betreuungsmaßnahmen zu haben. In der psychiatrischen Versorgung von Menschen in akuten psychiatrischen Krisensituationen muss das Thema mehr Aufmerksamkeit erfahren.
description: Intensive care measures are used in acute psychiatric emergency situations in inpatient psychiatric treatment. It is a complex intervention in which multiple aspects of psychiatric care interact with each other. Different methods have been used. First, results of a systematic literature review on intensive care measures are presented. Secondary data has been evaluated to show the importance of the topic in psychiatric care. Finally, the issue of intensive care has been put into a wider context and considered in a multi-center study in five different clinics. The results show that intensive care measures are complex interventions because they combine a large number of interacting components. The application of the measures in the participating clinics of the multicentre study is very different. Quantitative aspects of staffing and general conditions seem to have an influence on the occurrence of conflict and containment and thus indirectly on the application of intensive care measures. The topic of intensive care measure needs to receive much more attention in the national psychiatric care practice of people in acute psychiatric crisis situations.
Mobility as a service : opportunities in the City of Austin

description: Mobility services are quickly and continually evolving, propelled by advancements in technology, leading towards improved convenience and seamless transition between mobility providers. Mobility providers and 3rd party organizations are evolving towards cross-compatibility of services, including planning and payment over a single platform, this is called mobility as a service (MaaS). Austin, Texas has been facing the challenges of an urban fabric dependent on personal vehicles for mobility, including traffic congestion, reductions in air quality, and a disproportionate burden on marginalized communities. Adoption and enhancement of MaaS platforms within the city of Austin can relieve reliance on personal vehicles and ultimately improve residential quality of life. Still an evolving technology, existing studies have proposed structures and infrastructure that need to be in place for successful MaaS deployment, though none have looked at opportunities within Austin, which this project seeks to find. Through evaluation of existing City of Austin planning documents, proposed frameworks for deployment by researchers, and understanding of existing and proposed plans for MaaS platforms, this work seeks to understand the viability and roadmap for deployment within Austin. Results place Austin very well equipped to produce and handle and functioning MaaS platform by utilizing existing infrastructural pieces and planned mobility development, these include the number of mobility alternatives, a robust public transit service and planned increases in density. This report provides context for both policies and infrastructure that is necessary for cities to implement a successful MaaS platform.

description: We examine scatter and bias in weak lensing selected clusters, employing both an analytic model of dark matter haloes and numerical mock data of weak lensing cluster surveys. We pay special attention to effects of the diversity of dark matter distributions within clusters. We find that peak heights of the lensing convergence map correlates rather poorly with the virial mass of haloes. The correlation is tighter for the spherical overdensity mass with a higher mean interior density. We examine the dependence of the halo shape on the peak heights, and find that the rms scatter caused by the halo diversity scales linearly with the peak heights with the proportionality factor of 0.1-0.2. The noise originated from the halo shape is found to be comparable to the source galaxy shape noise and the cosmic shear noise. We find the significant halo orientation bias, i.e., weak lensing selected clusters on average have their major axes aligned with the line-of-sight direction. We compute the orientation bias using an analytic triaxial halo model and obtain results quite consistent with the ray-tracing results. We develop a prescription to analytically compute the number count of weak lensing peaks taking into account all the main sources of scatters in peak heights. We find that the improved analytic predictions agree well with the simulation results for high S/N peaks. We also compare the expected number count with our weak lensing analysis results for 4 sq deg of Subaru/Suprime-Cam observations and find a good agreement.
