Facilitating Uav Application For Cav Deployment, Shuya Zong, Yujie Li, Sikai Chen, Shaoshuai Mou, Samuel Labi

Center for Connected and Automated Transportation

Connectivity-equipped UAVs offer communication opportunities within CAV ecosystems. This study was motivated by challenges in UAV-based monitoring: (a) at intersections where road user trajectories could be irregular, leading to traffic conflicts or collisions, and (b) during inclement weather where video images are often corrupted by falling rain streaks thus impairing the integrity of the image. In response to these challenges, the study developed and demonstrated the efficacy of (a) an algorithm for UAVs to predict vehicle trajectories at intersections and (b) a 2-stage self-supervised algorithm for enhancing the quality of UAV-sourced images. Both parts of the study highlight the UAV …

Center for Connected and Automated Transportation

Cost-effective ways to obtain and distribute traffic data, and thereby, to facilitate operations decisions. This includes a need to make Signal Phase and Timing (SPaT) and MAP data more useful to traffic data end-users. Existing data collection and delivery methods are time consuming and costly. Therefore, to facilitate traffic operations in the current era of human-driven vehicles (HDVs) and the prospective era of connected autonomous vehicles (CAVs), this research developed a device to acquire, process, and disseminate SPaT data from Traffic Signal Controller (TSC) cabinets in a manner that ensures system integrity and yet fosters accessibility of timing information for …

Purdue University Libraries Open Access Publishing Fund

Drawing on servicescape theory, this research investigates guests’ perceptions of and responses to the protection and prevention practices launched by hotels at different stages of the pandemic. The research finds that hotel guests’ general response-efficacy beliefs positively influence their perception of the effectiveness of the protection and prevention practices adopted in hotels’ physical and social servicescapes, and such positive relationships also show a significant increase from 2020 to 2021. The servicescape effects’ downstream results show that hotel guests are willing to pay premium prices for safety servicescapes manifested as protection and prevention practices implemented at the private space or related …


Tellurium Corrosion Of Type 304/304l Stainless Steel, Iron, Chromium, And Nickel In High-Temperature Liquid Sodium, Yi Xie Oct 2023

Tellurium Corrosion Of Type 304/304l Stainless Steel, Iron, Chromium, And Nickel In High-Temperature Liquid Sodium, Yi Xie

Purdue University Libraries Open Access Publishing Fund

Investigating tellurium (Te) corrosion on structural materials is crucial for sodium-cooled fast reactors (SFRs) due to radionuclide presence and knowledge gaps. In this study, Type 304/304L stainless steel (SS304), chromium (Cr), iron (Fe), and nickel (Ni) samples were immersed in low-oxygen environments with Te in liquid sodium at 773 K for 30 days. At 10 ppm oxygen, SS304 showed multiple oxide layers, including a compact NaCrO2 interlayer and porous Na-Fe-Ni-O outer layers. Tellurium penetrated through the porous layers but was hindered by the NaCrO2 interlayer. At 0.01 ppm oxygen, Cr had no oxide layer, while Fe and Ni had unstable …

Us Climate Policy Yields Water Quality Cobenefits In The Mississippi Basin And Gulf Of Mexico, Shan Zuidema, Jing Liu, Maksym Chepeliev, David R. Johnson, Uris Baldos, Steve Frolking, Christopher J. Kucharik, Wilfred M. Wollheim, Thomas Hertel

Department of Agricultural Economics Faculty Publications

We utilize a coupled economy–agroecology–hydrology modeling framework to capture the cascading impacts of climate change mitigation policy on agriculture and the resulting water quality cobenefits. We analyze a policy that assigns a range of United States government’s social cost of carbon estimates ($51, $76, and $152/ton of CO2-equivalents) to fossil fuel–based CO2 emissions. This policy raises energy costs and, importantly for agriculture, boosts the price of nitrogen fertilizer production. At the highest carbon price, US carbon emissions are reduced by about 50%, and nitrogen fertilizer prices rise by about 90%, leading to an approximate 15% reduction in fertilizer applications for …

Vistac Toward A Unified Multimodal Sensing Finger For Robotic Manipulation, Sheeraz Athar, Gaurav Patel, Zhengtong Xu, Qiang Qiu, Yu She

School of Industrial Engineering Faculty Publications

Tactile sensors are crucial in providing contact geometry information necessary for object manipulation. However, it remains highly nontrivial for a tactile sensor to be able to perceive a distant object before manipulation. In this work, we present an innovative robotic finger, VisTac, which seamlessly combines high-resolution tactile and visual perception in a single unified device, while adhering to essential mechanical constraints, such as a human-finger-like wedge-shaped top, vital for manipulation tasks. Furthermore, we discuss the fabrication of a key component in the device; the semitransparent membrane with light-dependent opacity, thus enabling the contact surface to effortlessly transition between visual and …


Review Of Fighting Invisibility: Asian Americans In The Midwest. Rutgers University Press, Xiang Zhou Oct 2023

Review Of Fighting Invisibility: Asian Americans In The Midwest. Rutgers University Press, Xiang Zhou

Journal of Southeast Asian American Education and Advancement

Despite the imperative to shed light on the experiences of Asian Americans residing in the Midwest, previous research has predominantly centered around Asians residing on the coasts. This phenomenon, as elucidated by Erika Lee in her concept of “doubly invisible” Midwest Asian Americans, highlights their dual marginalization—they are not only conspicuously absent from mainstream literature but also from the broader discourse on Asian American experiences, which primarily revolves around those on the East and West coasts. However, it is within the heartland of America that we witness one of the most profound transformations in Asian America over the past few …

Neuronal Nadph Oxidase Is Required For Neurite Regeneration Of Aplysia Bag Cell Neurons, S.M. Sabbir Alam, Yuichiro Watanabe, Brooke L. Steeno, Soumyajit Dutta, Halie A. Szilagyi, Alexander Wei, Daniel M. Suter

Department of Chemistry Faculty Publications

NADPH oxidase (Nox), a major source of reactive oxygen species (ROS), is involved in neurodegeneration after injury and disease. Nox is expressed in both neuronal and non-neuronal cells and contributes to an elevated ROS level after injury. Contrary to the well-known damaging effect of Nox-derived ROS in neurodegeneration, recently a physiological role of Nox in nervous system development including neurogenesis, neuronal polarity, and axonal growth has been revealed. Here, we tested a role for neuronal Nox in neurite regeneration following mechanical transection in cultured Aplysia bag cell neurons. Using a novel hydrogen peroxide (H2O2)-sensing dye, 5′-(p-borophenyl)-2′-pyridylthiazole pinacol ester (BPPT), we …


Westernization Or Localization? The (Mis)Reading Of “The Tragic” In Modern Chinese Literary Discourse, Tian Gu Oct 2023

Westernization Or Localization? The (Mis)Reading Of “The Tragic” In Modern Chinese Literary Discourse, Tian Gu

CLCWeb: Comparative Literature and Culture

This paper examines the features and causal factors in constructing an idea of the tragic in modern Chinese literary discourse. It attempts at revisiting and reproducing the realities of misreading and variation upon modern Chinese introduction of the term “tragedy” (beiju) at different socio-historical periods, and has observed the interplay between two trends, namely, Westernization and localization, through the negotiation of “the tragic” into modern Chinese literary practice. These two trends have been integrated by a political and pragmatic perspective, which dominates the formation of a modern Chinese literary discourse on “the tragic”. This perspective offers both possibility …


Children’S Gothic In The Chinese Context: The Untranslatability And Cross-Cultural Readability Of A Literary Genre, Chengcheng You Oct 2023

Children’S Gothic In The Chinese Context: The Untranslatability And Cross-Cultural Readability Of A Literary Genre, Chengcheng You

CLCWeb: Comparative Literature and Culture

As an emerging literary subgenre in the twenty-first century, Children’s Gothic challenges and blends the norms of both children’s literature and Gothic literature, featuring child characters’ self-empowerment in the face of fears and dark impulses. The foreignness and strangeness that pertain to the genre haunt the border of its translatability. Daniel Handler’s A Series of Unfortunate Events (1999­–2006), written under the pseudonym Lemony Snicket, poses a chain of translational challenges due to its linguistic creativity, paratextual art, and mixed style of horror and dark humor intended for a child readership. To investigate the interplay between Children’s Gothic and its (un)translatability …


Playing With Time: Writing History In Neo-Zionist Hebrew Literature, Huiruo Li Oct 2023

Playing With Time: Writing History In Neo-Zionist Hebrew Literature, Huiruo Li

CLCWeb: Comparative Literature and Culture

The term neo-Zionism can be used to group ideologically much of contemporary Hebrew literature. However, since neo-Zionism shares similar critical tools with post-Zionism, while also sharing a common political vision with Zionism, it has been difficult to find the definitive signifiers of neo-Zionist writing. This paper offers a way to determine the nuanced ideological inclination of Hebrew literature: the presentation of time. First, this paper recognizes the metamorphosis of time in Israeli literary history that reflects the writers’ historical view of the Zionist agenda. Zionist Hebrew literature was engaged in re-establishing Jewish historical time by emphasizing the relationship between time …


The Animal In The Wild In Hwang Sun-Mi’S The Hen Who Dreamed She Could Fly, Sarah Yoon Oct 2023

The Animal In The Wild In Hwang Sun-Mi’S The Hen Who Dreamed She Could Fly, Sarah Yoon

CLCWeb: Comparative Literature and Culture

Hwang Sun-mi’s The Hen Who Dreamed She Could Fly has become a contemporary classic children’s story in Korea since its original publication in 2000. Since then, the story has been translated and redesigned with new illustrations in almost thirty different countries (Y. Kim). The Hen Who Dreamed She Could Fly centers on a hen that raises a duckling as her “baby,” with the story drawing upon a rich reservoir of cultural associations between humans and nature in East Asian traditions. In this story, the hen leaves the human-dominated barnyard, based on profit, exploitation, and competition, for a reconnection with moral …


Translating Diversity From Ralph Ellison To Kenzaburō Ōe, Raphaël Lambert Oct 2023

Translating Diversity From Ralph Ellison To Kenzaburō Ōe, Raphaël Lambert

CLCWeb: Comparative Literature and Culture

The purpose of this article is twofold: first, it endeavors to understand the vagaries of the notion of diversity as it travels from one national and political context to the next; and second, it shows how two major fiction writers and essayists have used that notion in their work and to what ends. The first part focuses on the work of Ralph Ellison, who put diversity at the heart of his reflection on what a truly democratic American society should be. Kenzaburō Ōe initially borrowed the notion of diversity from Ellison himself, but as the second part demonstrates, Ōe did …


Fam210a Is Essential For Cold-Induced Mitochondrial Remodeling In Brown Adipocytes, Jiamin Qiu, Feng Yue, Peipei Zhu, Jingjuan Chen, Fan Xu, Lijia Zhang, Kun Ho Kim, Madigan M. Snyder, Nanjian Luo, Hao-Wei Xu, Fang Huang, W. Andy Tao, Shihuan Kuang Oct 2023

Fam210a Is Essential For Cold-Induced Mitochondrial Remodeling In Brown Adipocytes, Jiamin Qiu, Feng Yue, Peipei Zhu, Jingjuan Chen, Fan Xu, Lijia Zhang, Kun Ho Kim, Madigan M. Snyder, Nanjian Luo, Hao-Wei Xu, Fang Huang, W. Andy Tao, Shihuan Kuang

Purdue University Libraries Open Access Publishing Fund

Cold stimulation dynamically remodels mitochondria in brown adipose tissue (BAT) to facilitate non-shivering thermogenesis in mammals, but what regulates mitochondrial plasticity is poorly understood. Comparing mitochondrial proteomes in response to cold revealed FAM210A as a cold-inducible mitochondrial inner membrane protein. An adipocyte-specific constitutive knockout of Fam210a (Fam210aAKO) disrupts mitochondrial cristae structure and diminishes the thermogenic activity of BAT, rendering the Fam210aAKO mice vulnerable to lethal hypothermia under acute cold exposure. Induced knockout of Fam210a in adult adipocytes (Fam210aiAKO) does not affect steady-state mitochondrial structure under thermoneutrality, but impairs cold-induced mitochondrial remodeling, leading to progressive loss of cristae and reduction of …

Journal of Pre-College Engineering Education Research (J-PEER)

This qualitative study applies Positioning Theory to identify positions that mediate the experiences of design failure within the context of an afterschool engineering club (EC) with elementary students diverse in language, race, ethnicity, gender, and academic abilities. We ask: (1) What kinds of structural design failure and failure responses did participants in EC experience? and (2) What are students’ and teachers’ positions in relation to responses to design failure? Types of positions (e.g., builder, tinkerer, idea-elicitor, director, observer) were identified in relation to children’s and teachers’ actions and speech in response to structural design failure during EC. Participants included 12 …


Complex Impacts Of Wars On Global Sustainable Development In A Metacoupled World, Qutu Jiang, Zhenci Xu, Yuanzheng Cui, Jianguo Liu Oct 2023

Complex Impacts Of Wars On Global Sustainable Development In A Metacoupled World, Qutu Jiang, Zhenci Xu, Yuanzheng Cui, Jianguo Liu

I-GUIDE Forum

Wars and armed conflicts have had profound impacts on local and global sustainable development in an interconnected world. However, evidence on the impacts of wars is fragmented and little attention has been paid to the impacts on the 17 UN’s Sustainable Development Goals (SDGs), a unifying framework for achieving global sustainable development. This perspective synthesizes the scattered information to provide a holistic analysis and highlight the applications of remote sensing in assessing the impacts of wars on global sustainable development in a metacoupling world. Wars have complex impacts on all 17 SDGs, which cascade beyond conflict zones and spillover to …

Deep Q-Learning Framework For Quantitative Climate Change Adaptation Policy For Florida Road Network Due To Extreme Precipitation, Orhun Aydin Oct 2023

Deep Q-Learning Framework For Quantitative Climate Change Adaptation Policy For Florida Road Network Due To Extreme Precipitation, Orhun Aydin

I-GUIDE Forum

Climate change-induced extreme weather and increasing population are increasing the pressure on the global aging road networks. Adaptation requires designing interventions and alterations to the road networks that consider future dynamics of flooding and increased traffic due to the growing population. This paper introduces a reinforcement learning approach to designing interventions for Florida's road network under future traffic and climate projections. Three climate models and a tide and surge model are used to create flooding and coastal inundation projections, respectively. The optimal sequence of decisions for adapting Florida's road network to minimize flooding-related disruptions is solved by using a graph-based …
