Authors: Wiethoff Alexander , Hoggenmueller Marius , Rossmy Beat , Hirsch Linda , Hespanhol Luke , Tomitsch Martin
Published: March 2022

The augmentation of the built and urban environment with digital media has evolved and matured over recent years. Cities are seeing a rapid rise of various technologies; a trend also accelerated by global crises. Consequently, new urban interfaces are emerging that integrate next-generation technologies, such as sustainable interface materials and urban robotic systems. However, their development is primarily driven by technological concerns, leaving behind social, aesthetic, and spatial considerations. By analyzing our own media architecture research projects and real-world applications from the past two decades, we offer a structural approach for developing these new urban interfaces. The individual cases provide early insights and challenges related to prototyping and augmenting contexts with novel input and output modalities. These results in common, preliminary observed patterns in the process of integrating next-generation technologies into urban environments and surroundings, in response to continuously evolving social needs.

Published: March 2022

This paper introduces a design framework for mixed reality urban exploration (MRUE), based on a concrete implementation in a historical city. The framework integrates different modalities, such as virtual reality (VR), augmented reality (AR), and haptics-audio interfaces, as well as advanced features such as personalized recommendations, social exploration, and itinerary management. It permits to address a number of concerns regarding information overload, safety, and quality of the experience, which are not sufficiently tackled in traditional non-integrated approaches. This study presents an integrated mobile platform built on top of this framework and reflects on the lessons learned.
Enhancing Urban Conversation for Smarter Cities – Augmented Reality as an enabler of digital civic participation
Authors: Hunter Michael , Soro Alessandro , Brown Ross
Published: March 2022

This paper presents a perspective on the role immersive technologies can play in the future of urban transformation. Specifically, this paper looks to answer the following questions – How can Augmented Reality be implemented as an enabler of civic participation in the urban transformation process? What specific and novel affordances does Augmented Reality present in this context? And how do these affordances demonstrate a unique interaction paradigm between citizens and cities? We review the current literature on future cities, urban transformation, digital civic participation and augmented reality usage to determine the current state of digitally enhanced urban transformation processes. As a result, we identify an opportunity in which recent developments in Augmented Reality technologies afford entirely new ways of approaching civic participation.We suggest new Augmented Reality technologies can be considered as a novel way to engage citizens in decision making processes and as a result improve the resilience, adaptability and sustainability of future cities. Augmented Reality can allow citizens and other stakeholders to visualise and imagine possible urban transformations, to contribute to an ongoing discussion between citizens and with city councils, and to participate in a feedback loop in which ideas are refined, analysed, and iterated in a collaborative process. We finally discuss challenges, tensions, and open issues of a research agenda aimed at developing immersive technologies for participatory urban transformation.
GeoACT: Augmented Control Tower using Virtual and Real Geospatial Data
Authors: Ssin Seungyoub , Cho Hochul , Woo Woontack
Published: March 2022

Despite prior efforts to solve urban problems and build smart cities using large-scale urban information, researchers have yet to develop tools for city administrators to easily access a diverse mix of city information. To address this limitation, this article proposes an augmented reality visualization system, GeoACT, which can develop a digital twin to present city information from both macro and micro perspectives. GeoACT employs a 3D virtual city miniature with real and virtual IoT information to provide a macro perspective view, and a 360-degree-video-based visualization technique is used for a micro perspective view. We applied GeoACT to an urban space and demonstrated that it could effectively visualize city information through an augmented reality Head Mounted Display (HMD). Furthermore, GeoACT can be used in urban control centers.

Authors: Gonsalves Kavita , Foth Marcus , Amayo Caldwell Glenda
Published: March 2022

The COVID-19 pandemic has made the struggles of the excluded louder and has also left them socially isolated. The article documents the implementation of one instance of Radical Placemaking, an “intangible”, community-driven and participatory placemaking process, in Kelvin Grove Urban Village (KGUV), Brisbane, Australia to tackle social isolation during the COVID-19 pandemic. KGUV community members were engaged in storytelling and interactive fiction online workshops to create experiential, place-based and mobile low-tech AR digital artefacts. The article expands on the methodology which involved a series of online workshops to design low-tech AR digital artefacts using digital collaboration tools (Google Classroom, Slack, Zoom) and VR environments (Mozilla Hubs). The study’s findings confirm the role of accessible AR/VR technology in enabling marginalised communities to create connectedness and community by co-creating their own authentic and diverse urban imaginaries of place and cities.

Published: March 2022

: Breast cancer is a heterogeneous disease in which many factors and receptors are effective in the disease process and response to treatment. Currently, estrogen, progesterone, and HER2 receptors are among the most important factors in choosing a treatment regimen. Other metabolic factors that may affect the treatment outcome include diabetes and hyperinsulinemia. In order to evaluate the role and complexity of cross-talk between different pathways initiating from various receptors, value the most common drugs in the treatment of breast cancer are investigated on different cell lines in this manuscript at the cell culture level. The result of different doses of Tamoxifen and estradiol on the cells with various levels of the estrogenic, progesterone, and HER2 receptors is examined alone, or in combinations, and the presence or absence of insulin. The effects of these variables on the cells' growth pattern and survival in various breast cancer cells are investigated using cell counting, colony counting, and MTT assays. Our results have further confirmed the complexity of deciding on the outcome of treatment for breast cancer with such a wide variability in the kind of receptors and biochemical agents present in the body of a cancer patient.

Authors: Ramzani Solale , Khanjani Narges , Mohammadyan Mahmoud , Babanezhad Esmaeil , Yazdani-charati Jamshid
Published: March 2022

Background: Manganese (Mn) is an essential element for the human body, but it can cause adverse effects on the Central Nervous System at high doses. Exposure to manganese fumes during welding can harm welders' health. Objectives: The current study aimed to measure manganese produced by shielded metal arc welding (SMAW) in the breathing zone air and blood of welders and investigate the relationship between manganese concentrations in air and blood. Methods: In this descriptive-analytical cross-sectional study, 35 welders were enrolled as the exposed group and 40 office workers as the control group. Manganese concentration in air was measured according to NIOSH method 7301. Air and blood sample analyses were carried out by ICP-OES. Statistical analysis was performed with MINITAB 17. Data were analyzed using Pearson correlation coefficient, one-sample t-test, paired t-test, and logistic regression. The significance level was set at P < 0.05. Result: The mean concentration of welding respirable particles and manganese fumes were 9.56 ± 1.67 and 0.45 ± 0.08 mg/m3, three and 22 times the exposure limit recommended by ACGIH, respectively. Average manganese was significantly higher in the welders’ blood (0.16 ± 0.02 µg/mL) than in the controls’ blood (0.04 ± 0.002 µg/mL). There were strong and significant correlations between the welding respirable particles and manganese concentration in welders’ breathing zone and blood manganese levels. Also, with each year of work experience, the manganese concentration in the welders’ blood increased by 1.5%. Conclusions: Welders are at risk of contamination with manganese. Manganese exposure reduction through more efficient ventilation systems, reducing welder’s exposure time, staff training, and appropriate respiratory protection equipment should be applied to reduce manganese exposure among welders and prevent health complications.
Reclaiming Reasoning
Authors: Wolfe Katharine ,   Philosophy Documentation Center
Published: March 2022

This article traces my own pedagogical journey to find strategies for teaching critical thinking that emphasize intellectual cooperation, empathy, and argument repair, a journey that found me frequently turning to sources outside of philosophy, including work in intergroup dialogue and pedagogical work in rhetoric and composition. Theoretically, the article showcases Maureen Linker’s notion of ‘cooperative reasoning’ (2015), sets it against the ‘adversary paradigm’ Janice Moulton critiques, and illustrates how Peter Elbow’s challenges to critical thinking as a ‘doubting game’ resonate with Linker’s work. Practically, it illustrates the structure and the role of peer-to-peer dialogues in my own reasoning classroom, an enactment of a cooperative, belief-based approach to reasoning inspired by Linker and Elbow alike, while also learning from the methodologies of intergroup dialogue.

It is an important way to increase students' interest in learning, deepen the understanding of esoteric and obscure theoretical knowledge, and catch up with the frontiers of international science. However, due to the limitations of school funding resources, laboratory conditions, and traditional teaching mode, there are many problems during the experimental teaching of "Semiconductor Physics and Devices", such as the insufficient proportion of comprehensive and innovative experiments, outdated experimental contents, and single limited teaching methods that cannot stimulate students' learning interests of students. In response to the abovementioned situation, combined with many years of experience in learning and teaching semiconductor courses and drawing lessons from the advanced teaching modes of international applied technology universities, we creatively adopt the new experimental and practical teaching mode of "in school experiment + out of school practice" and "in-class experiment + extracurricular innovation project expansion". Network interesting experiments and international cutting-edge research topics (such as organic optoelectronic materials) are introduced into our innovative experiments and practical teaching, such as preparing new organic light-emitting pn junction diodes and quantum dot light-emitting diodes, and perovskite thin-film solar cells. Students deeply love these teaching reform measures, stimulate their interest in learning and scientific research, and significantly improve their ability to solve practical problems or scientific research innovation ability, which have achieved preliminary results. The accumulated teaching experience will provide a reference for developing semiconductor physics and devices experimental courses for semiconductor or optoelectronics and microelectronics majors in application-oriented universities.

In order to enhance the spin orbit interaction (SOI) in graphene for seeking the dissipationless quantum spin Hall devices, unique Kane-Mele-type SOI and high mobility samples are desired. However, the common external modification of graphene often introduces “extrinsic” Rashba-type SOI, which will destroy the possible topological state, bring a certain degree of impurity scattering and reduce the sample mobility. Here we show that by the EDTA-Dy molecule dressing, the carrier mobility is even improved, and the quantum Hall plateaus are observed more clearly. The Kane-Mele type SOI is mimicked after dressing, which is evidenced by the suppressed weak localization at equal carrier densities and simultaneous Elliot-Yafet spin relaxation. This is attributed to the spin-flexural phonon coupling induced by the enhanced graphene ripples, as revealed by the in-plane magnetotransport measurement.
