The Energy Transition And Mining: Reconciling The Growth Of Renewable Energy With The Need For New Mineral Development, Alexandra B. Klass, Allison J. Mitchell

Articles

Under the Paris Agreement, the global governmental signatories embraced the goal to hold global average temperature increase to “well below 2°C above pre-industrial levels” while “pursuing efforts to limit the temperature increase to 1.5°C above pre-industrial levels.” Almost every country in the world signed on to the Paris Agreement, adopting the prevailing science that anthropocentric greenhouse gas emissions would result in rising global temperatures and catastrophic damages from climate change in the absence of immediate action. In pursuit of this goal, the signatories agreed that all member countries would work together to bring greenhouse gas emissions to zero within the …

Rhetorical Body Work: Professional Embodiment In Health Provider Education And The Technical Writing Classroom, Lillian Campbell

English Faculty Research and Publications

This article introduces “rhetorical body work” as a framework for understanding professional embodiment in health provider education and technical and professional communication (TPC) pedagogy. Using the case study of clinical nursing simulations and drawing on sociological theory, I provide a detailed analysis of three components of rhetorical body work as they manifest in three simulation scenarios: physical, emotional, and discursive. I conclude by considering the implications of these findings for the embodied teaching of TPC.

Advancing Applied Research In Conservation Criminology Through The Evaluation Of Corruption Prevention, Enhancing Compliance, And Reducing Recidivism, Jessica S. Kahler, Joseph W. Rivera, Zachary T. Steele, Pilar Morales-Giner, Christian J. Rivera, Carol F. Ahossin, Ashpreet Kaur, Diane J. Episcopio-Sturgeon

Biological Sciences Faculty Publications

Concomitant with an increase in the global illegal wildlife trade has been a substantial increase in research within traditional conservation-based sciences and conservation and green criminology. While the integration of criminological theories and methods into the wildlife conservation context has advanced our understanding of and practical responses to illegal wildlife trade, there remain discrepancies between the number of empirical vs. conceptual studies and a disproportionate focus on a few select theories, geographical contexts, and taxonomic groups. We present three understudied or novel applications of criminology and criminal justice research within the fields of fisheries, forestry, and wildlife conservation. First, we …

Microsphere Photolithography Patterned Nanohole Array On An Optical Fiber, Ibrahem Jasim, Jiayu Liu, Chen Zhu, Muhammad Roman, Jie Huang, Edward Kinzel, Mahmoud Almasri

Electrical and Computer Engineering Faculty Research & Creative Works

Microsphere Photolithography (MPL) is a nanopatterning technique that utilizes a self-assembled monolayer of microspheres as an optical element to focus incident radiation inside a layer of photoresist. The microspheres produces a sub-diffraction limited photonic-jet on the opposite side of each microsphere from the illumination. When combined with pattern transfer techniques such as etching/lift-off, MPL provides a versatile, low-cost fabrication method for producing hexagonal close-packed metasurfaces. This article investigates the MPL process for creating refractive index (RI) sensors on the cleaved tips of optical fiber. The resonant wavelength of metal elements on the surface is dependent on the local dielectric environment …

Data-Driven Identification Of Governing Partial Differential Equations For The Transmission Line Systems, Yanming Zhang, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Discovering governing equations for transmission line is essential for the study on its properties, especially when the nonlinearity is introduced in a transmission line system. In this paper, we propose a novel data-driven approach for deriving the governing partial differential equations based on the spatial-temporal samples of current and voltage in the transmission line system. The proposed method is based on the ridge regression algorithm to determine the active spatial differential terms from the candidate library that includes nonlinear functions, in which the time and spatial derivatives are estimated by using polynomial interpolation. Three examples, including uniform and nonuniform transmission …

Development And Characterization Of Nb₃N/Al₂0₃ Superconducting Multilayers For Particle Accelerators, Chris Sundahl, Junki Makita, Paul B. Welander, Yi-Feng Su, Fumitake Kametani, Lin Xie, Huimin Zhang, Lian Li, Alex Gurevich, Chang-Beom Eom

Physics Faculty Publications

Superconducting radio-frequency (SRF) resonator cavities provide extremely high quality factors > 10¹⁰ at 1-2 GHz and 2 K in large linear accelerators of high-energy particles. The maximum accelerating field of SRF cavities is limited by penetration of vortices into the superconductor. Present state-of-the-art Nb cavities can withstand up to 50 MV/m accelerating gradients and magnetic fields of 200-240 mT which destroy the low-dissipative Meissner state. Achieving higher accelerating gradients requires superconductors with higher thermodynamic critical fields, of which Nb₃Sn has emerged as a leading material for the next generation accelerators. To overcome the problem of low vortex penetration …

Electroosmotic Flow Of Viscoelastic Fluid Through A Constriction Microchannel, Jianyu Ji, Shizhi Qian, Zhaohui Liu

Mechanical & Aerospace Engineering Faculty Publications

Electroosmotic flow (EOF) has been widely used in various biochemical microfluidic applications, many of which use viscoelastic non-Newtonian fluid. This study numerically investigates the EOF of viscoelastic fluid through a 10:1 constriction microfluidic channel connecting two reservoirs on either side. The flow is modelled by the Oldroyd-B (OB) model coupled with the Poisson–Boltzmann model. EOF of polyacrylamide (PAA) solution is studied as a function of the PAA concentration and the applied electric field. In contrast to steady EOF of Newtonian fluid, the EOF of PAA solution becomes unstable when the applied electric field (PAA concentration) exceeds a critical value for …

Mechanism For The Unfolding Of The Top7 Protein In Steered Molecular Dynamics Simulations As Revealed By Mutual Information Analysis, Ognjen Perišić, Willy Wriggers

Mechanical & Aerospace Engineering Faculty Publications

We employed mutual information (MI) analysis to detect motions affecting the mechanical resistance of the human-engineered protein Top7. The results are based on the MI analysis of pair contact correlations measured in steered molecular dynamics (SMD) trajectories and their statistical dependence on global unfolding. This study is the first application of the MI analysis to SMD forced unfolding, and we furnish specific SMD recommendations for the utility of parameters and options in the TimeScapes package. The MI analysis provided a global overview of the effect of perturbation on the stability of the protein. We also employed a more conventional trajectory …

Electrical and Computer Engineering Faculty Research & Creative Works

Children with Autism Spectrum Disorder (ASD) exhibit a wide diversity in type, number, and severity of social deficits as well as communicative and cognitive difficulties. It is a challenge to categorize the phenotypes of a particular ASD patient with their unique genetic variants. There is a need for a better understanding of the connections between genotype information and the phenotypes to sort out the heterogeneity of ASD. In this study, single nucleotide polymorphism (SNP) and phenotype data obtained from a simplex ASD sample are combined using a PheWAS-inspired approach to construct a phenotype-phenotype network. The network is clustered, yielding groups …

Polycystic Kidney Disease: An Examination And Review Of Disease Type, Presentation, Treatment, And Prognosis, Zoey Mann

Biology and Microbiology Graduate Students Plan B Research Projects

Polycystic Kidney Disease (PKD) is a ciliopathy that primarily presents as renal cysts. Inherited as either a dominant (ADPKD) or recessive (ARPKD) mutation, PKD is one of the most commonly inherited kidney diseases. ADPKD is caused by the inheritance of a mutation in either PKD1 or PKD2, which code for the polycystin-1 and -2 proteins, respectively. The less severe form of PKD, ADPKD is typically adult-onset, with the possibility of extremely late-stage presentation. In addition to renal cysts, hepatic and pancreatic cysts are common, as well as other non-cystic symptoms including headache and hypertension. ARPKD is caused by the inheritance …

Biology and Microbiology Graduate Students Plan B Research Projects

Guillain-Barre Syndrome is a rare post-infection inflammatory disorder. It is caused by the cross-reactivity of antibodies produced from a recent infection which then attack the gangliosides of the peripheral nervous system. Guillain-Barre syndrome includes multiple subtypes which are categorized based on both disease course and symptoms, which include length of progression phase, pain, and cranial nerve involvement. This paper will serve as a review of diagnostic tools and treatment options used for Guillain-Barre syndrome patients. It will also discuss recent research on these topics as well as studies on viral outbreaks which may be linked to Guillain-Barre syndrome. These will …

Current And Future Perspectives In The Treatment Of Fracture Nonunions, Zebadiah Nelson

Biology and Microbiology Graduate Students Plan B Research Projects

Fracture nonunions comprise one of the serious clinical complications in orthopedics. Fracture nonunions result when the time to union is greater than 6 to 9 months. It is estimated that approximately 5% to 10% of all fractures progress to fracture nonunion due to a host of complicating patient variables and risk factors. New scoring systems have emerged which help in directing the treatment strategies. Fracture nonunion management should be directed toward maintaining the diamond concept which introduces osteogenic cells lines, an osteoconductive scaffold for those cells to grow, as well as the necessary growth factors, and a stable mechanical microenvironment. …

Biology and Microbiology Graduate Students Plan B Research Projects

Colorectal cancer is one of the top leading causes of cancer deaths affecting people of different ages, sex and races disproportionately. The American Cancer society researchers have studied that lack of physical activities, smoking, consumption of red meat, and heavy alcohol use to be high risk factors for developing colorectal cancer in addition to genetic inheritances. Previous research studies have shown that disparities in cancer screening, socioeconomic status and others impacts on colorectal cancer prevalence and death. The objective of this project is to review the existing literature to better understand the disparities in colorectal cancer prevalence and deaths in …

The Importance Of Care Coordination Of Patients With Multimorbidity: An Evaluation Of The Patient-Centered Medical Home Model, Mary Boksa

Biology and Microbiology Graduate Students Plan B Research Projects

The rise in multimorbidity among various patient populations has made fragmentation of care an increasingly common issue due to the need for specialized care of each chronic condition and complexity of treatment plans. Implementation of care coordination intervention models has been identified as an essential component in combating this fragmented nature of our current health care system. This is done by providing an organized model of care and improving communication between all parties involved in care and treatment plans. This literature review will begin with a brief discussion on the importance of care coordination and components needed for implementation and …

The Relationship Between Land Use Change And Disease Prevalence, Allison Bjornstad

Biology and Microbiology Graduate Students Plan B Research Projects

Zoonotic disease outbreaks are becoming more novel and are increasing in frequency. This increase can be partially attributed to land use changes including deforestation, urbanization, and cultivation. Land use change alters disease prevalence by causing an increase in contact rates between disease hosts and humans. Land use changes also alter species compositions in the area to contain more competent disease hosts. Each pathogen can react to these changes in different ways. The specific reactions that each pathogen has to land use changes should be further researched so proper mitigation steps can be taken. Once the effects of land use change …

Evolution Of Three Streambanks Before And After Stabilization And Record Flooding, Matthew Russell, Aaron R. Mittelstet, Tiffany Messer, Jesse T. Korus, R.M. Joeckel

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Stabilization projects are increasingly used to mitigate the effects of anthropogenic streambank erosion, yet the effectiveness of stabilization has been insufficiently measured. Sound monitoring practices inform adjustments in implementation and maintenance, which improve engineered effectiveness. Thus, the objectives of this study were to: 1) measure streambank migration from in three reaches stabilized with wooden jetties following a major flooding event, and 2) quantify deposition around the jetties between pre-flood and post-flood. Streambank deposition was measured in 2019 with a River Surveyor and Global Positioning System (GPS). Bank erosion rates in Reaches 1, 2 and 3 were 0.41, 0.96 and 0.07 …

Density Data For Lake Ontario Benthic Invertebrate Assemblages From 1964 To 2018, Lyubov E. Burlakova, Alexander Karatayev, Allison R. Hrycik, Susan Daniel, Knut Mehler, Lars G. Rudstam, James M. Watkins, Ronald Dermott, Jill Sharold, Ashley K. Elgin, Thomas F. Nalepa, Elizabeth K. Hinchey, Stephen J. Lozano

Great Lakes Center Faculty Publications

Benthic invertebrates are important trophic links in aquatic food webs and serve as useful bioindicators of environmental conditions because their responses integrate the effects of both water and sediment qualities. However, long-term data sets for benthic invertebrate assemblages across broad geographic areas are rare and, even if collected, historic data sets are often not readily accessible. This data set provides densities of benthic macroinvertebrates for all taxa collected during lake-wide surveys in Lake Ontario, a Laurentian Great Lake, from 1964 to 2018. This information resulted from surveys funded by the governments of the United States and Canada to investigate the …

A Repeated Triple Lysine Motif Anchors Complexes Containing Bone Sialoprotein And The Type Xi Collagen A1 Chain Involved In Bone Mineralization, Jeff P. Gorski, Nichole T. Franz, Daniel Pernoud, Andrew Keightley, David R. Eyre, Julia Thom Oxford

Biology Faculty Publications and Presentations

While details remain unclear, initiation of woven bone mineralization is believed to be mediated by collagen and potentially nucleated by bone sialoprotein (BSP). Interestingly, our recent publication showed that BSP and type XI collagen form complexes in mineralizing osteoblastic cultures. To learn more, we examined the protein composition of extracellular sites of de novo hydroxyapatite deposition which were enriched in BSP and Col11a1 containing an alternatively spliced “6b” exonal sequence. An alternate splice variant “6a” sequence was not similarly co-localized. BSP and Col11a1 co-purify upon ion-exchange chromatography or immunoprecipitation. Binding of the Col11a1 “6b” exonal sequence to bone sialoprotein was …

Monitoring Tropical Forest Succession At Landscape Scales Despite Uncertainty In Landsat Time Series, T. Trevor Caughlin, Cristina Barber, Gregory P. Asner, Nancy F. Glenn, Stephanie A. Bohlaman, Chris H. Wilson

Biology Faculty Publications and Presentations

Forecasting rates of forest succession at landscape scales will aid global efforts to restore tree cover to millions of hectares of degraded land. While optical satellite remote sensing can detect regional land cover change, quantifying forest structural change is challenging. We developed a state-space modeling framework that applies Landsat satellite data to estimate variability in rates of natural regeneration between sites in a tropical landscape. Our models work by disentangling measurement error in Landsat-derived spectral reflectance from process error related to successional variability.We applied our modeling framework to rank rates of forest succession between 10 naturally regenerating sites in Southwestern …

Als-Induced Excitability Changes In Individual Motorneurons And The Spinal Motorneuron Network In Sod1-G93a Mice At Symptom Onset, Christiana S.I. Draper

Browse all Theses and Dissertations

Amyotrophic lateral sclerosis (ALS) is the most common motorneuron (MN) disease in adulthood. ALS is hallmarked by the progressive loss of MNs in the brain, brainstem, and spinal cord. Many hypotheses to explain the pathogenesis of ALS have been explored, but the exact mechanisms underlying the development of this disease remain unknown. However, abnormalities in MN excitability and glutamate excitotoxicity are the most widely studied. For decades, researchers have examined MN excitability in ALS, but the current literature is inconsistent, showing evidence of hyperexcitability, hypoexcitability, or no change in excitability of MNs in ALS. Many of these studies also focus …
