The Effects Of Misspecifying The Random Part Of Multilevel Models, David M. Lahuis, Daniel R. Jenkins, Michael J. Hartman, Shotaro Hakoyama, Patrick C. Clark

Psychology Faculty Publications

This paper examined the amount bias in standard errors for fixed effects when the random part of a multilevel model is misspecified. Study 1 examined the effects of misspecification for a model with one Level 1 predictor. Results indicated that misspecifying random slope variance as fixed had a moderate effect size on the standard errors of the fixed effects and had a greater effect than misspecifying fixed slopes as random. In Study 2, a second Level 1 predictor was added and allowed for the examination of the effects of misspecifying the slope variance of one predictor on the standard errors …

Assessment Of Soil Properties Under Different Land Use Types In Olokemeji Forest Reserves In Ogun State Southwestern Nigeria, Oluwatoyin Opeyemi Akintola, Adewunmi Idayat Bodede, Michael Smart, Ayodeji Gideon Adebayo, Olawale Nurean Sulaiman

Journal of Bioresource Management

Knowledge of soil properties is essential for environmental sustainability for any forest reserve or plantation. The physical and chemical properties of soil under three different land uses was investigated to assess the nutrient and fertility status of the soils. Fifteen soil samples, each collected from different locations within the natural forest, plantation and farm land were analyzed for soil texture, bulk density, porosity, pH, organic carbon, organic matter content, total nitrogen, available phosphorus, Na, K, Ca, Mg, Zn, Cu, Fe and Mn. Texturally, the soils were loamy, loamy sand and sandy loamy in the natural forest, plantation and farmland respectively. …

Effects Of Neuronic Shutter Observed In The Eeg Alpha Rhythm, Kevin E. Alexander, Justin R. Estepp, Sherif M. Elbasiouny

Neuroscience, Cell Biology & Physiology Faculty Publications

The posterior alpha (α) rhythm, seen in human electroencephalogram (EEG), is posited to originate from cycling inhibitory/excitatory states of visual relay cells in the thalamus. These cycling states are thought to lead to oscillating visual sensitivity levels termed the “neuronic shutter effect.” If true, perceptual performance should be predictable by observed α phase (of cycling inhibitory/excitatory states) relative to the timeline of afferentiation onto the visual cortex. Here, we tested this hypothesis by presenting contrast changes at near perceptual threshold intensity through closed eyelids to 20 participants (balanced for gender) during times of spontaneous α oscillations. To more accurately and …

A Nonlinear Distortion Removal Based On Deep Neural Network For Underwater Acoustic Ofdm Communication With The Mitigation Of Peak To Average Power Ratio, Xuefei Ma, Waleed Raza, Zhiqiang Wu, Muhammad Bilal, Ziqi Zhou, Amir Ali

Electrical Engineering Faculty Publications

Machine learning and deep learning algorithms have proved to be a powerful tool for developing data-driven signal processing algorithms for challenging engineering problems. This paper studies the modern machine learning algorithm for modeling nonlinear devices like power amplifiers (PAs) for underwater acoustic (UWA) orthogonal frequency divisional multiplexing (OFDM) communication. The OFDM system has a high peak to average power ratio (PAPR) in the time domain because the subcarriers are added coherently via inverse fast Fourier transform (IFFT). This causes a higher bit error rate (BER) and degrades the performance of the PAs; hence, it reduces the power efficiency. For long-range …

Flux Pinning Enhancements Of Yba2cu3o7-X With Nanosize Magnetic Additions, M. A. Sebastian, N. A. Pierce, I. Maartense, Gregory Kozlowski, T. J. Haugan

Physics Faculty Publications

Different methods of flux pinning are being tested world-wide to enhance critical currents (Ics) of high temperature superconductor YBa2Cu3O7-x (YBCO) coated conductors exposed to high magnetic fields. Magnetic materials are interesting to consider as flux pinning additions because of their potential for very strong pinning strength. To our knowledge, there have been limited demonstrations of magnetic pinning additions to YBCO conductors. This paper describes the study of different M magnetic phase additions to YBCO including M = BaFe12O19, La0.67Ca0.33MnO3, and other oxide phases. Nanosize additions were incorporated by depositing multilayer (M/YBCO)N films to minimize degradation of Tc, and testing volume …

Prediction Of Feed Utilization Performance In Clarias Gariepinus Using Multiple Linear Regression In Machine Learning, Adekunle Oluwatosin Familusi

Journal of Bioresource Management

Machine learning models can be used to make predictions about nutrient utilization performance index using available proximate analysis data on feed composition. Data from similar experiments on nutrient utilization performance was used to fit a multiple linear regression model for the prediction of four performance indexes. The Specific Growth Rate and percentage inclusion with strength of 0.57 was noted along with a negative relationship between protein efficiency and protein content. A negative relationship between Nitrogen Free Extract (NFE) and Protein Efficiency Ratio (PER) at NFE content ≥25 % was observed. PER was predicted with 85 % accuracy, while Weight Gain …

The different features of soil greatly affect the flora and vegetative diversity of a forest. The physical and chemical characteristics of soils in Onigambari Forest Reserve were evaluated to assess the fertility and productivity status of the soils. Fifteen soil samples collected from different sample locations were analyzed for soil texture (sand, silt and clay), bulk density, porosity, pH, organic matter, total nitrogen, available phosphorus, exchangeable bases (Na, K, Ca and Mg) and available micronutrients (Zn, Cu, Fe and Mn). Texturally, the studied soils were loamy sand and sandy loam with percentage of sands (71.2-84.2 %), silts (7.4-10.4 %) and …

Effects Of Growth Temperature On Electrical Properties Of Gan/Aln Based Resonant Tunneling Diodes With Peak Current Density Up To 1.01 Ma/Cm2, Evan M. Cornuelle, Tyler A. Growden, David F. Storm, Elliott R. Brown, Weidong Zhang, Brian P. Downey, Vikrant Gokhale, Laura B. Ruppalt, James G. Champlain, Prudhvi Peri, Martha R. Mccartney, David J. Smith, David J. Meyer, Paul R. Berger

Physics Faculty Publications

Identical GaN/AlN resonant tunneling diode structures were grown on free-standing bulk GaN at substrate temperatures of 760 ○C, 810 ○C, 860 ○C, and 900 ○C via plasma-assisted molecular beam epitaxy. Each sample displayed negative differential resistance (NDR) at room tem- perature. The figures-of-merit quantified were peak-to-valley current ratio (PVCR), yield of the device with room-temperature NDR, and peak current density (Jp). The figures-of-merit demonstrate an inverse relationship between PVCR/yield and Jp over this growth temperature series. X-ray diffraction and transmission electron microscopy were used to determine the growth rates, and layer thicknesses were used to explain the varying figures-of-merit. Due …

Potential For Wetlands To Remediate Harmful Pathogenic Fecal Coliform Bacteria From Streams, C. Ewing, Benjamin Strang, Bradley Axe, Jocelyn Birt, Brayden Kinney, Zachary Senger, Stephen J. Jacquemin

Lake Campus Research Symposium Abstracts and Posters

Wetlands are increasingly becoming a cornerstone of stream remediation in the highly eutrophic regions of the Midwestern United States. Wetlands have numerous advantages over other technologies as they incorporate natural biological process resultant from plants and bacteria while also providing an increase in wildlife habitat and greenspaces rather than relying on costly and technologically complex processes to treat waterways. The capacity for wetlands to remediate nutrients and improve water clarity is fairly well established. However, less is known about their potential to affect changes in the pathogenic microbial communities (such as E. coli) commonly associated with runoff in agricultural areas …

Continuous Water Quality Monitoring Platform For Grand Lake St Marys, Aaron Neikamp, Alex Lehman, Brandon Siefring, Jason Evers, Ryan M. Spicer, Shayna R. Petitjean

Lake Campus Research Symposium Abstracts and Posters

For the past decade, Grand Lake St. Marys (GLSM) has struggled to provide a stable and clean water source for the community affecting people and businesses alike. A safe level of microcystin –a toxin in the harmful algal blooms–is 20 ppb in recreational water, and GLSM has seen an excess of 82 ppb. As of now, there is no solution to continuously monitor the water quality; therefore, corrective actions are only based off intermittent samples taken by hand. A solution to this issue would be a water quality platform (WQP) that monitors parameters such as water and air temperature, conductivity, …

The Relationship Between Object-Based Judgments And Judgments Of Relative Direction As Measures Of Spatial Memory, Zachary Carpenter, Tressa Molinar, Herbert A. Colle

Celebration of Undergraduate & Graduate Research, Scholarship, and Creative Activities Materials

There are frequently two different conceptions used to describe what people store in their memory for environmental layouts. The SOLAR (Straight-Line Object-Based, Local Angular Relations) model and the quasi-Euclidean Framework model. The Framework model assumes that people store coordinated points in their layout of spatial memory. This grid-like representation of points is then used to remember layouts. A common, natural judgment that is used within the Framework model are called judgments of relative direction (JRDs). The SOLAR model, on the other hand, assumes people remember and store information about 3D objects, so characteristics such as fronts can be used as …

Snakes On A Plain: Paleontology, Archeology, And History Of The Rattlesnake And Garter Snake In Western Ohio, Ryan Shell, David Peterman, Charles Ciampaglio, Stephen J. Jacquemin

Lake Campus Research Symposium Abstracts and Posters

During an investigation of caves in Taylorsville Metropark, near Dayton, Ohio, vertebral remains of rattlesnake (Crotalus sp.) and garter snake (Thamnophis sp.) were recovered from sites radiocarbon dated to a the historical period (~146 years before present) and to the Hopewell Archeological period (~1,433 years before present). The latter specimens recovered represent the some of the oldest sub-fossil evidence of the migration of these genera into the plains and forests of Ohio. A review of scientific and historical records for each genus indicates thatThamnophis appeared in the region prior to the end of the Pleistocene Epoch and persisted in abundance …

Functional Sites Within The Ihnv Nonvirion Protein That Regulate Host Cellular Responses, Jeff Ringiesn, Bartolomeo Gorgoglione, Douglas W. Leaman

Celebration of Undergraduate & Graduate Research, Scholarship, and Creative Activities Materials

Fish Rhabdoviruses are responsible for causing fatal epizootics within commercial and wild populations of various fish species around the world. Infectious hematopoietic necrosis virus (IHNV), also known as the Salmonid novirhabdovirus, is enzootic along the Pacific Coast of North America and is comprised of five genogroups, each of which is endemic to a specific geographical location. Once the virus enters the host through the fin epithelia, IHNV infection causes infectious hematopoietic necrosis in salmonid species. The disease is highly fatal and presents with signs such as abdominal distension, bulging of the eyes, anemia, and necrosis of vital organs such as …

Tip60 Regulation Of Δnp63Α Is Associated With Cisplatin Resistance, Akshay Hira, Andrew Stacy, Jin Zhang, Michael P. Craig, Madhavi Kadakia

Celebration of Undergraduate & Graduate Research, Scholarship, and Creative Activities Materials

About 5.4 million basal and squamous cell skin cancers are diagnosed every year in the US. ΔNp63a, a member of the p53 transcription factor family, is overexpressed in non-melanoma skin cancer and regulates cell survival, migration and invasion. TIP60 is histone acetyltransferase (HAT) which mediates cellular processes such as transcription and the DNA damage response (DDR). Previous studies in our lab have shown that overexpression of TIP60 induces ΔNp63a protein stabilization in a catalytic-dependent manner. Since ΔNp63a is known to transcriptionally regulate several DDR genes and promote cisplatin resistance, its stabilization by TIP60 may contribute to the failure of platinum-based …

Multi-Label Model For Toxicity Prediction, Xiu Huan Yap, Michael L. Raymer

Celebration of Undergraduate & Graduate Research, Scholarship, and Creative Activities Materials

Most computational predictive models are specifically trained for a single toxicity endpoint. Since more than 1300 toxicity assays have been reported in the TOXCAST dashboard, achieving high coverage over this growing number of toxicity endpoints remains challenging. Furthermore, single-endpoint models lack the ability to learn dependencies between endpoints, such as those targeting similar biological pathways, which may be used to boost model performance. In this study, we characterize the performance of 3 multi-label classification (MLC) models, namely Classifier Chains (CC), Label Powersets (LP) and Stacking (SBR), on Tox21 challenge data. These MLC models employ the Problem Transformation approach, which is …
