Evaluation Of The Community Multiscale Air Quality Model For Simulating Winter Ozone Formation In The Uinta Basin, Rebecca Matichuk, Gail Tonnesen, Deborah Luecken, Rob Gillam, Sergey L. Napelenok, Kirk R. Baker, Donna Schwede, Ben Murphy, Detlev Helmig, Seth N. Lyman, Shawn Roselle

Bingham Research Center

The Weather Research and Forecasting (WRF) and Community Multiscale Air Quality (CMAQ) models were used to simulate a 10 day high-ozone episode observed during the 2013 Uinta Basin Winter Ozone Study (UBWOS). The baseline model had a large negative bias when compared to ozone (O₃) and volatile organic compound (VOC) measurements across the basin. Contrary to other wintertime Uinta Basin studies, predicted nitrogen oxides (NO_x) were typically low compared to measurements. Increases to oil and gas VOC emissions resulted in O₃ predictions closer to observations, and nighttime O₃ improved when reducing the deposition velocity …

The Use Of Artificial Neural Network To Optimize The Ph Response Range Of Chlorophenol Red, Wong F., Ahmad M., Heng L. Y.

ASEAN Journal on Science and Technology for Development

Artificial Neural Network (ANN) had been used in this study to extend the response range of the pH indicator. The input from absorbance values of the absorbance spectra of chlorophenol red at different pH was used to train the ANN. During the training process, the coefficient values of the ANN will be adjusted to obtain the desire output. In this research, back propagation algorithm had been used for optimizing the response range of the pH indicator chlorophenol red in solution. The result indicates that the use of ANN enable the pH response range to be extended from 4.8-6.8 to 1.0-10.0.

Entropy Learning In Neural Network, Ng Geok See, Shi D., Wahab A., Singh H.

ASEAN Journal on Science and Technology for Development

In this paper, entropy term is used in the learning phase of a neural network. As learning progresses, more hidden nodes get into saturation. The early creation of such hidden nodes may impair generalisation. Hence entropy approach is proposed to dampen the early creation of such nodes. The entropy learning also helps to increase the importance of relevant nodes while dampening the less important nodes. At the end of learning, the less important nodes can then be eliminated to reduce the memory requirements of the neural network.

Exploring The Use Of A Time-Frequency Domain Technique For The Filtering Of Acoustic Emission/Microseismic Data, Charles Mborah, Maochen Ge, Zhigang Wang

Mining Engineering Faculty Research & Creative Works

The performance of acoustic emission/micro seismic (AE/MS) monitoring systems in mines is greatly impacted by background noise interference. Mine trucks/vehicles, fans, blasting and electrical spikes generate noise which negatively affect AE/MS signal quality. Using such datasets without filtering may lead to inaccurate determination of first arrivals and hence wrong source location. Also, data contaminated with noise makes manual identification and picking of the first arrivals impossible or difficult to achieve. This paper explored the use of stationary discrete wavelet transform as a filter to augment noise reduction on mine AE/MS data. The output of a test run on both noisy …

Agency Theory And Corporate Governance In China: A Meta-Analysis, Canan C. Mutlu, Marc Van Essen, Mike W. Peng, Sabrina F. Saleh

Faculty Articles

Do agency theory-based “good corporate governance” principles indeed apply to China? A straightforward answer to this question is lacking, because evidence is inconclusive across studies. We endeavor to fill this gap by conducting the first meta-analysis on the China literature with two focuses. First, we assess the impact of (i) board independence, (ii) board leadership structure, and (iii) managerial incentives on firm performance, as these elements have been central to both agency theory as well as to Chinese corporate governance reforms. Second, we extend current theorizing by showing support for the temporal hypothesis, which states that over time, with the …

Design Of A Hvdc-Based Controller For Load Change Compensation And Stabilization Of Inter-Area Oscillations, Ngamroo I.

ASEAN Journal on Science and Technology for Development

As an interconnected power system via a High-Voltage Direct Current (HVDC) link is subjected to a rapid load change with the frequency of inter-area oscillation mode, system frequency and tie line power may be severely disturbed and oscillate. To compensate for the rapid load change and stabilize both frequency and tie line power oscillations due to the inter-area mode, the dynamic power flow control via a HVDC link can be exploited. To implement this concept, a new design method of HVDC-based controller is proposed. To grasp a physical characteristic of the inter-area oscillation frequency, the technique of overlapping decompositions is …

Serine-Dependent Sphingolipid Synthesis Is A Metabolic Liability Of Aneuploid Cells, Sunyoung Hwang, H. Tobias Gustafsson, Ciara O’Sullivan, Gianna Bisceglia, Xinhe Huang, Christian Klose, Andrej Schevchenko, Robert C. Dickson, Paola Cavaliere, Noah Dephoure, Eduardo M. Torres

Molecular and Cellular Biochemistry Faculty Publications

Aneuploidy disrupts cellular homeostasis. However, the molecular mechanisms underlying the physiological responses and adaptation to aneuploidy are not well understood. Deciphering these mechanisms is important because aneuploidy is associated with diseases, including intellectual disability and cancer. Although tumors and mammalian aneuploid cells, including several cancer cell lines, show altered levels of sphingolipids, the role of sphingolipids in aneuploidy remains unknown. Here, we show that ceramides and long-chain bases, sphingolipid molecules that slow proliferation and promote survival, are increased by aneuploidy. Sphingolipid levels are tightly linked to serine synthesis, and inhibiting either serine or sphingolipid synthesis can specifically impair the fitness …

The Relationship Between Black And Gay Community Involvement And Hiv-Related Risk Behaviors Among Black Men Who Have Sex With Men, Dexter R. Voisin

ETSU Faculty Works

LIMD1 (LIM domain-containing protein 1) is considered as a tumor suppressor, being deregulated in many cancers to include hematological malignancies; however, very little is known about the underlying mechanisms of its deregulation and its roles in carcinogenesis. Epstein-Barr Virus (EBV) is associated with a panel of malignancies of lymphocytic and epithelial origin. Using high throughput expression profiling, we have previously identified LIMD1 as a common marker associated with the oncogenic transcription factor IRF4 in EBV-related lymphomas and other hematological malignancies. In this study, we have identified potential conserved IRF4- and NFκB-binding motifs in the LIMD1 gene promoter, and both are …

Ultrasonic Neuromodulation In Vitro At Single Neuron Resolution, Sheikh Ilham

Master's Theses

Ultrasound as a widely used imaging means for medical diagnosis has drawn growing interests as a potential noninvasive neuromodulation strategy. Focused pulsed ultrasound effectively modulates neural encoding and transmission functions especially in the peripheral nervous system (PNS) with unclear mechanism of action, which is further confounded by contradictory experimental outcomes. Lack of convincing experimental methods has hindered our mechanistic understanding of ultrasonic PNS neuromodulation. To address that, we developed a novel in vitro set up to achieve simultaneous single-unit recordings from individual mouse sciatic nerve axon and systematically studied the effect of focused pulsed ultrasound (FPUS) on action potential transmission …

Research Publications (2016 to 2020)

Enterococcus faecium is both a commensal of the human intestinal tract and an opportunistic pathogen. The increasing incidence of enterococcal infections is mainly due to the ability of this organism to develop resistance to multiple antibiotics, including vancomycin. The aim of this study was to perform comparative genome analyses on four vancomycin-resistant Enterococcus faecium (VREfm) strains isolated from two fatal cases in a tertiary hospital in Malaysia. Two sequence types, ST80 and ST203, were identified which belong to the clinically important clonal complex (CC) 17. This is the first report on the emergence of ST80 strains in Malaysia. Three of …

Evaluating Behavioral Responses Of Nesting Lesser Snow Geese To Unmanned Aircraft Surveys, Andrew Barnas, Robert Newman, Christopher J. Felege, Michael P. Corcoran, Samuel D. Hervey, Tanner J. Stechmann, Robert F. Rockwell, Susan N. Ellis-Felege

Publications and Research

Unmanned aircraft systems (UAS) are relatively new technologies gaining popularity among wildlife biologists. As with any new tool in wildlife science, operating protocols must be developed through rigorous protocol testing. Few studies have been conducted that quantify the impacts UAS may have on unhabituated individuals in the wild using standard aerial survey protocols. We evaluated impacts of unmanned surveys by measuring UAS-induced behavioral responses during the nesting phase of lesser snow geese (Anser caerulescens caerulescens) in Wapusk National Park, Manitoba, Canada. We conducted surveys with a fixed-wing Trimble UX5 and monitored behavioral changes via discreet surveillance cameras at 25 nests. …
