Challenging The Notion Of Role Models In Engineering Outreach Programs For Youth, Kelli M. Paul, Karen Miel, Merredith D. Portsmore, Adam Maltese Oct 2023

Challenging The Notion Of Role Models In Engineering Outreach Programs For Youth, Kelli M. Paul, Karen Miel, Merredith D. Portsmore, Adam Maltese

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

Engineering outreach programs often portray outreach educators as role models for youth. It is widely believed that introducing youth, especially girls, to potential engineering role models will broaden participation in engineering majors and careers. Based on interviews with and surveys of fourth- and fifth-grade girls participating in an engineering outreach program, we question whether youth are looking for career role models, and we challenge the assumption that youth will take up an adult as a role model simply because the adult is presented as such. We question what role these ‘‘models’’ play in the minds and lives of youth and …

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 …

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 …

Large-Scale Google Street View Images For Urban Change Detection, Fangzheng Lyu, Xinlin Ma, Yan Song, Eric Zhu, Shaowen Wang

I-GUIDE Forum

Urbanization has entered a new phase characterized by urban changes occurring at a micro-scale and “under the roof”, as opposed to external modifications. These changes, known as urban retrofitting, involve the incorporation of novel technologies or features into pre-existing systems to promote sustainability. Given the limitations of remote sensing images in identifying such urban changes, novel tools need to be developed for detecting urban retrofitting. In this study, we first build a pipeline to collect large-scale time-series urban street view images from Google Street View in Mecklenburg County, North Carolina. And we examine the feasibility of utilizing the acquired dataset …

Graph Transformer Network For Flood Forecasting With Heterogeneous Covariates, Jimeng Shi, Vitalii Stebliankin, Zhaonan Wang, Shaowen Wang, Giri Narasimhan

I-GUIDE Forum

Floods can be very destructive causing heavy damage to life, property, and livelihoods. Global climate change and the consequent sea-level rise have increased the occurrence of extreme weather events, resulting in elevated and frequent flood risk. Therefore, accurate and timely flood forecasting in coastal river systems is critical to facilitate good flood management. However, the computational tools currently used are either slow or inaccurate. In this paper, we propose a Flood prediction tool using Graph Transformer Network (FloodGTN) for river systems. More specifically, FloodGTN learns the spatio-temporal dependencies of water levels at different monitoring stations using Graph Neural Networks (GNNs) …

How To Treat Alzheimer’S Disease By Boosting Glymphatic Flow: Simulations In A New Computational Model, Charles F. Babbs Oct 2023

How To Treat Alzheimer’S Disease By Boosting Glymphatic Flow: Simulations In A New Computational Model, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

This study exercises a new mathematical model to search for unappreciated therapeutic targets in Alzheimer’s disease. The model describes detailed mechanisms underlying the glymphatic pump mechanism, which removes toxic proteins of Alzheimer’s disease from the interstitial fluid of the brain. It shows that the glymphatic pump is driven by the amplitude of intracranial pressure pulsations in the subarachnoid space, which are correlated with the arterial pulse and modulated by many other factors. Implementing ways to increase intracranial pressure pulses quickly comes to mind as a potential treatment strategy. Specific interventions include drugs that increase arterial pulse volume and small devices …

Solving Geospatial Problems Under Extreme Time Constraints: A Call For Inclusive Geocomputational Education, Coline C. Dony Oct 2023

Solving Geospatial Problems Under Extreme Time Constraints: A Call For Inclusive Geocomputational Education, Coline C. Dony

I-GUIDE Forum

To prepare our next generation to face geospatial problems that have extreme time constraints (e.g., disasters, climate change) we need to create educational pathways that help students develop their geocomputational thinking skills. First, educators are central in helping us create those pathways, therefore, we need to clearly convey to them why and in which contexts this thinking is necessary. For that purpose, a new definition for geocomputational thinking is suggested that makes it clear that this thinking is needed for geospatial problems that have extreme time constraints. Secondly, we can not further burden educators with more demands, rather we should …

Reducing Uncertainty In Sea-Level Rise Prediction: A Spatial-Variability-Aware Approach, Subhankar Ghosh, Shuai An, Arun Sharma, Jayant Gupta, Shashi Shekhar, Aneesh Subramanian

I-GUIDE Forum

Given multi-model ensemble climate projections, the goal is to accurately and reliably predict future sea-level rise while lowering the uncertainty. This problem is important because sea-level rise affects millions of people in coastal communities and beyond due to climate change's impacts on polar ice sheets and the ocean. This problem is challenging due to spatial variability and unknowns such as possible tipping points (e.g., collapse of Greenland or West Antarctic ice-shelf), climate feedback loops (e.g., clouds, permafrost thawing), future policy decisions, and human actions. Most existing climate modeling approaches use the same set of weights globally, during either regression or …

A New Empirical Law For The Prediction Of The Zero-Lift Pitching Moment Coefficient Of Swept And Tapered Wings, Mondher Yahyaoui Sep 2023

A New Empirical Law For The Prediction Of The Zero-Lift Pitching Moment Coefficient Of Swept And Tapered Wings, Mondher Yahyaoui

Journal of Aviation Technology and Engineering

A new empirical law for the prediction of the zero-lift pitching moment coefficient of trapezoidal wings with linear twist and constant taper and sweep in subsonic flow is introduced. This law is quite general in that it does not rely on the use of charts and spans the normal range of values of taper ratio, aspect ratio, and sweep for subsonic aircraft. It does not, however, accommodate different airfoils along the wingspan and only positive sweep has been considered. The empirical law was first derived for the incompressible regime and then an additional empirical law for the compressibility effect has …

Observation Of Self-Patterned Defect Formation In Atomic Superfluids–From Ring Dark Solitons To Vortex Dipole Necklaces, Hikaru Tamura, Cheng-An Chen, Chen-Lung Hung Sep 2023

Observation Of Self-Patterned Defect Formation In Atomic Superfluids–From Ring Dark Solitons To Vortex Dipole Necklaces, Hikaru Tamura, Cheng-An Chen, Chen-Lung Hung

Purdue University Libraries Open Access Publishing Fund

Unveiling nonequilibrium dynamics of solitonic and topological defect structures in a multidimensional nonlinear medium is a current frontier across diverse fields. One of the quintessential objects is a ring dark soliton (RDS), whose dynamics are expected to display remarkable interplay between symmetry and self-patterned topological defect formation from a transverse (snake) instability, but it has thus far evaded full experimental observations. Here, we report an experimental realization of RDS generation in a two-dimensional atomic superfluid trapped in a circular box. By quenching the confining box potential, we observe an RDS emitted from the edge and its peculiar signature in the …

Optimization Of Extreme Ultra-Violet Light Emitted From The Co2 Laser-Irradiated Tin Plasmas Using 2d Radiation Hydrodynamic Simulations, Atsushi Sunahara, Ahmed Hassanein, Kentaro Tomita, Shinichi Namba, Takeshi Higashiguchi

Purdue University Libraries Open Access Publishing Fund

We studied Extreme Ultra-Violet (EUV) emission characteristics of the 13.5 nm wavelength from CO2 laser-irradiated pre-formed tin plasmas using 2D radiation hydrodynamic simulations. Our results indicate that when a CO2 laser irradiates pre-formed tin plasma, the heated plasma expands towards the surrounding plasma, steepening the density at the ablation front and lowering the density near the laser axis due to the transverse motion of the plasma. Consequently, the laser absorption fraction decreases, and the contribution to EUV output from the ablation front becomes dominant over that from the low-density plasmas. We estimated that an EUV conversion efficiency of 10% from …

A Decision Aid To Help Farmers Find The Minimum Cost Fertilizer Combination, Gregory Ibendahl Sep 2023

A Decision Aid To Help Farmers Find The Minimum Cost Fertilizer Combination, Gregory Ibendahl

Journal of Applied Farm Economics

Fertilizer recommendations are typically given as the pounds of nitrogen, phosphorus, and potassium needed per acre. Many crop budgets also list the fertilizer costs in terms of the N, P, and K. This can cause a problem for farmers as they must purchase their fertilizer in products that in some cases contain multiple nutrients. These multinutrient fertilizers make it difficult or impossible to calculate a price per unit of a nutrient. Thus, finding the minimum cost fertilizer combination by using a price per nutrient approach may not work. This paper shows how a linear programming approach will always give the …

Comparison Of Conservation Instruments Under Long-Run Yield Uncertainty And Farmer Risk Aversion, Meilin Ma, Carson Reeling, Megan N. Hughes, Shalamar Armstrong, Richard Roth Sep 2023

Comparison Of Conservation Instruments Under Long-Run Yield Uncertainty And Farmer Risk Aversion, Meilin Ma, Carson Reeling, Megan N. Hughes, Shalamar Armstrong, Richard Roth

Department of Agricultural Economics Faculty Publications

Consumers and policymakers are increasingly concerned with environmental sustainability in food production. Yet rates of adoption of many conservation practices vary and are generally low. Existing instruments for practice adoption increase farmers’ expected net benefits from sustainable practices but do not manage associated risks which may be critical to risk-averse farmers. We build a model to characterize practice adoption by risk-averse farmers given practice-driven, long-run yield dynamics under various instruments, including price premiums, lump-sum subsidies and green insurance. We find rich scale and compositional effects that differ across instruments and that green insurance is significantly more cost-effective under plausible conditions.

Department of Chemistry Faculty Publications

Freeze-dried CNFs can be modified by mechanochemical (MC) processes with minimal use of auxiliary solvents, however aggregation of nanofibers during lyophilization compromises their granularity and reaction efficiency. Adding 10 wt% tert-butanol (TBA) to aqueous slurries of wood-derived CNF creates a eutectic mixture that reduces hornification during lyophilization, resulting in well-formed aerogels with minimal shrinkage in volume. CNFs lyophilized from mixtures containing at least 10 wt% TBA exhibit an order of magnitude increase in specific surface area relative to CNFs freeze-dried from water alone. The amount of TBA and input energy needed for lyophilization can be reduced considerably by dewatering …
