Abstract Funding Acknowledgements Type of funding sources: Private company. Main funding source(s): Abbott Background 3D mapping systems are pivotal to identify low voltage areas and to define ablation strategies. In this context, high-density multipolar mapping catheters with varying electrode configurations are used for accurate myocardial substrate definition. High density mapping using a grid shaped catheter allows for use of simultaneous analysis of adjacent orthogonal bipolar signals that may assist in more accurate substrate characterization and ablation strategy decisions. Purpose This was a prospective, multicenter observational study to characterize the utility of electroanatomical mapping with a high density grid-style mapping catheter (HD Grid) in subjects undergoing catheter ablation for persistent atrial fibrillation (PersAF) or ventricular tachycardia (VT) in real-world clinical settings. Methods Mapping was performed with the HD Grid catheter to generate high-density maps of cardiac chambers in order to assess the potential influence of the simultaneous orthogonal bipole configuration on PersAF and VT ablation strategies. Differences in substrate identification between simultaneous orthogonal bipole configuration and standard along-the-spline electrode configuration, and potential effects on ablation strategies were investigated. Results During the study period (January 2019 through April 2020), 367 subjects underwent catheter ablation for PersAF (N = 333, average age 64.1yr, 75% male) or VT (N = 34, average age = 64.3yr, 85.3% male). In total, 494 maps were generated to treat patients undergoing PersAF ablation and 57 to treat patients undergoing VT ablation. Compared to standard along-the-spline configuration, mapping with the simultaneous orthogonal bipole configuration showed differences in 57.8% (178/308) of maps generated, with the greatest difference noticed in surface area of low voltage (62.9%) and location of low voltage (55.6%). In comparisons performed live during the procedure (n = 50), simultaneous orthogonal bipole configuration assisted in identification of ablation targets in 70.0% of cases, changing the ablation strategy compared to that identified with along-the-spline configuration in 34.3%. In comparisons performed retrospectively after the procedure (n = 258), the ablation strategy identified with simultaneous orthogonal bipole configuration differed from along-the-spline configuration in 21.7% of maps. Even compared to a higher-density electrode configuration using all-bipoles rather than along-the-spline bipoles, simultaneous orthogonal bipole configuration identified differences in 57.1% of maps. Conclusion The HD grid catheter combined with simultaneous orthogonal bipole configuration can define myocardial substrate more accurately compared to standard along-the-spline configuration. The difference in substrate identification has potential impact on ablation strategy. Further clinical trials are needed to elucidate the role of orthogonal bipole configuration mapping and improved ablation success rates.

The Spatial Audio Data Immersive Experience (SADIE) project aims to identify new foundational relationships pertaining to hu-man spatial aural perception, and to validate existing relation-ships. Our infrastructure consists of an intuitive interaction in-terface, an immersive exocentric sonification environment, and a layer-based amplitude-panning algorithm. Here we highlight the system’s unique capabilities and provide findings from an initial externally funded study that focuses on the assessment of human aural spatial perception capacity. When compared to the existing body of literature focusing on egocentric spatial perception, our data show that an immersive exocentric environment enhances spatial perception, and that the physical implementation using high density loudspeaker arrays enables significantly improved spatial perception accuracy relative to the egocentric and virtual binaural approaches. The preliminary observations suggest that human spatial aural perception capacity in real-world-like immersive exocentric environments that allow for head and body movement is significantly greater than in egocentric scenarios where head and body movement is restricted. Therefore, in the design of immersive auditory displays, the use of immersive exocentric environments is advised. Further, our data identify a significant gap between physical and virtual human spatial aural perception accuracy, which suggests that further development of virtual aural immersion may be necessary before such an approach may be seen as a viable alternative.

<p>The Aotearoa (New Zealand) housing crisis and environmental shifts have inspired this thesis, which will address contemporary issues regarding Landscape Architecture, housing and urban design in Maungawhau (Mount Eden), Tāmaki-Makaurau (Auckland). Certain design decisions and some areas of local and national policy have restricted property development (or allowed poor development to occur). These developments have also limited infrastructural progress particularly in regard to sustainable urban planning strategies throughout Tāmaki-Makaurau in the past two decades in particular. The population of Tāmaki-Makaurau is rapidly growing, the 2018 census revealed a population increase of 11% in the past five years. Tāmaki-Makaurau is home to roughly 1.6million people, which is 1/3rd of Aotearoa‘s population. House prices reached an all-time high in 2016, causing major concern at a national level.  To tackle these issues of improving sustainable infrastructure and high-density housing this thesis will create a design strategy which will form a new urban fabric for Eden Park. The Master Planning strategy will take a cross-disciplinary approach. Involving Landscape Architecture, elements or urbanism, architecture and hydrology. The landscape, and water sensitive design will be the key drivers in how the housing mosaic is formed. Eden Park will be used as a blank canvas site of 105,300m2. The applied design will evolve as the site challenges the aims of the thesis, methods will be tested and the project will adapt as the site develops, the implementation of precedent and methods will be displayed in the design development and final design. This will result in a robust Master Planning strategy. A detailed urban design strategy will be a solution to the challenges set out in the thesis statement. The design development for Eden Park will intertwine with the wider Maungawhau network, this will be displayed in the final design drawings. The wetland will aim to treat a larger catchment of the area of 1,026,130.33m2, this means that the wetland will need to be roughly 20,000m2 so that the total catchment can be treated by this artificial wetland at 2%. The design goal is to create a multi-layered high-density housing assemblage and mixed use space that will stand as an example of a contemporary water sensitive and high-density design in action. The final design will be strong, versatile, and have the potential to be developed and expanded into wider networks over time in regard to using similar design strategy. I envisage a successful landscape design framework as a tool that aims to design more cohesive, innovative, adaptive and local high-density urban plans, which will respond to the demands of a growing population, ever-changing environmental conditions, and overall enhance a better quality of life.</p>

Negative Impacts

Cities are densifying at a rapid rate, and accordingly, are constructing high-rise buildings to accommodate more people. The aim of this study was to quantify the physiological and psychological impacts of being in the presence of high-rise buildings in Central London, in a real and virtual 360-degree video environment. Using a within-subjects design, participants were exposed to a low-rise and high-rise building. While exposed, participants were monitored for electrodermal activity. They were also administered the Self-Assessment Manikin measure and a cognitive appraisal questionnaire. Participants rated the high-rise building environment to be less open, less friendly and rated themselves to feel less happy and have less sense of control, as compared to low-rise buildings. We found these effects in both the real world (n = 16) and a 360-degree video setting (n = 121). These findings suggest that city environments populated with high-rise buildings can have negative impacts on urban dwellers. Furthermore, this study provides a methodology to examine how individuals respond to the built environment and stands to inform urban design and architectural practices.

The Real

Design education, especially in an undergraduate course of study, seeks to prepare students for professions and for citizenship in a world they hardly know. The studio typically provides only a surrogate experience in addressing formal and spatial problems, and is limited by time, by its geographic space, and by a dialogue that is more often than not, self-referential. It very rarely engages systemic questions of public policy, or the specific challenges of implementing at full scale ideas that are conceived through representational means. The constrained intellectual context is most poignantly seen in the urban design studios where problems are situated in the real world, and where issues outside the purview of design are found embedded in a place. Form-focused studio exercises that are necessarily a part of beginning architecture education are inadequate for exploring the indeterminacy of urban space and the complexity of human environments. When students enter an urban design studio, especially when they undertake community-based projects, they must take up the mantle of citizenship and engage in an enterprise that is fundamentally relational and grounded in experience. They need more information and more ways of knowing the world than traditionally the design disciplines can offer. This paper presents the outcomes of an experimental neighborhood-based teaching project undertaken as a collaboration among classes in architecture, landscape architecture, urban geography and the fine arts at Temple University. Although initiated through the architecture faculty’s desire to enrich its own undergraduate urban design studio, all the collaborators shared our concern about the narrowing effects of disciplinary bracketing on student learning, especially when the goal was to address real world situations. Each discipline brought to the project its particular disciplinary culture -- its language, methodology and areas of concern -- and a shared aspiration to puzzle together these diverse perspectives around questions of making places that are meaningful, humane and sustainable. The struggles and synergies among disciplines were alternatively inspiring, annoying, challenging, rich and imperfect. But intense engagement with a community re-centered the dialogue from inside the academic context to outside, and framed a multidisciplinary way of thought. The community itself proved to be a powerful coalescing agent; the inherent layering of issues in the real-world context made it virtually impossible to remain insensible to interdependencies in life that transcend disciplinary boundaries. Here Richard Sennett’s definition of what constitutes a democratic urbanity was applicable. The Greek term for “public”, synkoikismos, means “to bring together in the same place people that need each other but worship different household gods.” (47) This deceptively simple public-making concept became the basis for a process of learning, and a vehicle for working with the larger truths about how cities are formed and experienced.

Local Climate Zone

Surface urban heat island (SUHI) depicts the deteriorating thermal environment in high-density cities and local climate zone (LCZ) classification provides a universal protocol for SUHI identification. In this study, taking the central urbanized area of Guangzhou in the humid subtropical region of China as the study area, the maps or images of LCZ, land surface temperature, SUHI, and urban design factors were achieved using Landsat satellite data, GIS database, and a series of retrieval and classification algorithms, and the urban design factors influencing SUHI were investigated based on 625 samples of LCZs. The results show that on the 18 September 2016 at the local time of 10:51 a.m., the land surface temperature (LST) varied greatly from 26 °C to 40 °C and the SUHI changed with a wide range of −6 °C to 8 °C in the LCZs of the study area. Seven and five urban design factors influencing the summer daytime SUHI were identified for the two dominant LCZs of LCZs 1–5 (LCZ 1 to LCZ 5) and the mixed LCZ (containing at least three types of LCZs), respectively, in which vegetation cover ratio, floor area ratio, ground emissivity, and complete surface area ratio showed negative correlations and building density showed positive correlations. The summer daytime SUHI prediction models were obtained by using the step-wise multiple linear regression, with the performance of R2 of 0.774, RMSE of 0.95 °C, and the d value of 0.91 for the model of LCZs 1–5, and the values of 0.819, 0.81 °C, and 0.94 for the model of the mixed LCZ, indicating that the models can effectively predict the changes of SUHI with LCZs. This study presents a methodology to efficiently achieve a large sample of SUHI and urban design factors of LCZs, and provides information beneficial to the urban designs and regenerations in high-density cities.
