Digital Holographic Microscopy Of Phase Separation In Multicomponent Lipid Membranes, Vahideh Farzam Rad, Ali-Reza Moradi, Ahmad Darudi, Lobat Tayebi

School of Dentistry Faculty Research and Publications

Lateral in-homogeneities in lipid compositions cause microdomains formation and change in the physical properties of biological membranes. With the presence of cholesterol and mixed species of lipids, phospholipid membranes segregate into lateral domains of liquid-ordered and liquid-disordered phases. Coupling of two-dimensional intralayer phase separations and interlayer liquid-crystalline ordering in multicomponent membranes has been previously demonstrated. By the use of digital holographic microscopy (DHMicroscopy), we quantitatively analyzed the volumetric dynamical behavior of such membranes. The specimens are lipid mixtures composed of sphingomyelin, cholesterol, and unsaturated phospholipid, 1,2-dioleoyl-sn-glycero-3-phosphocholine. DHMicroscopy in a transmission mode is an effective tool for quantitative visualization of phase …

Graphene Oxide - Gold Nanostar Based Sensor For Chemiresistor And Sers Sensing, Justin Bae, Srikanth Singamaneni

Mechanical Engineering and Materials Science Independent Study

As part of a bigger project of building a multimodal electronic nose for 2,4 di-nitro toluene and 2,4,6 trinitrotoluene, the objective of this study was to develop a novel type of sensor to detect specific analytes and their concentrations. A chemiresistor based system involving gold and graphene nanostructures is proposed so that it has both chemiresistive and SERS sensing capabilities (fig. 1). It was expected that if succeeded, the sensor would show clearly the orthogonality between the optical SERS reading and the chemiresistive reading in terms of sensing analytes. This study hopes to eventually integrate chemiresistor sensing and SERS sensing …

Analysis Of Small Muscle Movement Effects On Eeg Signals, Erhan E. Yanteri

Theses and Dissertations

In this thesis, the artefactual effects of the small muscle movements were investigated. Upper frequency bands (30 Hz) of the EEG signal were extracted in order to investigate the artefactual effects of the small muscle movements. When the contamination level is high, the detection of the small muscle artifact can be made with the 92.2% accuracy. If these artifacts are really small such as a single finger movement, the detection accuracy decreases to 64%. But, the detection accuracy increases to 72% after removing the eye blink artifacts. The results of the classification support our hypothesis about the artefactual effects of …

Integrated Circuit Wear-Out Prediction And Recycling Detection Using Radio-Frequency Distinct Native Attribute Features, Randall D. Deppensmith

Theses and Dissertations

Radio Frequency Distinct Native Attribute (RF-DNA) has shown promise for detecting differences in Integrated Circuits(IC) using features extracted from a devices Unintentional Radio Emissions (URE). This ability of RF-DNA relies upon process variation imparted to a semiconductor device during manufacturing. However, internal components in modern ICs electronically age and wear out over their operational lifetime. RF-DNA techniques are adopted from prior work and applied to MSP430 URE to address the following research goals: 1) Does device wear-out impact RF-DNA device discriminability?, 2) Can device age be continuously estimated by monitoring changes in RF-DNA features?, and 3) Can device age state …

Kinetics Of Graphite Oxidation In Reacting Flow From Imaging Fourier Transform Spectroscopy, Ashley E. Gonzales

Theses and Dissertations

This work focuses on the characterization of laser irradiated graphite oxidation using mid-wave infrared (MWIR) imaging Fourier transform spectroscopy (IFTS). Although graphite oxidation has been studied extensively, IFTS uniquely provides spatial characterization of the reacting plumes. Spatial maps of species and temperature provide much needed insight into the transport and kinetic mechanisms and are vital for validation of numerical efforts. The current study builds on previous work using IFTS to characterize graphite oxidation in buoyant flow. Buoyant flow measurements are expanded to a wider range of graphite materials and surface temperatures. Oxidation in flat plate shear flow and stagnation flow …

An Information Theoretic Investigation Of Complex Adaptive Supply Networks With Organizational Topologies, Joshua V. Rodewald

Theses and Dissertations

Supply networks exist throughout society in manufacturing and knowledge-intensive industries as well as many service industries. Organizations have been noted to behave as complex adaptive systems or information supply networks with both formal and informal structures. Thoroughly understanding supply network structure and behavior are critical to managing such organizations effectively, but their properties of complex adaptive systems make them more difficult to analyze and assess, forcing researchers to rely on unrealistic data or assumptions of behavior. This research proposes an information theoretic methodology to discover such complex network structures and dynamics while overcoming the difficulties historically associated with their study. …

Reflection Matrix Method For Controlling Light After Reflection From A Diffuse Scattering Surface, Kenneth W. Burgi

Theses and Dissertations

This research focuses on reflective inverse diffusion, which was a proof-of-concept experiment that used phase modulation to shape the wavefront of a laser causing it to refocus after reflection from a rough surface. By refocusing the light, reflective inverse diffusion has the potential to eliminate the complex radiometric model of indirect photography by creating a virtual light source at the first diffuse reflector that satisfies the line-of-sight requirement of dual photography. However, the initial reflective inverse diffusion experiments provided no mathematical background and were conducted under the premise that the process operated similarly to transmissive inverse diffusion.

In this research, …

A Machine Learning Approach For Using The Postmortem Skin Microbiome To Estimate The Postmortem Interval, Hunter R. Johnson, Donovan D. Trinidad, Stephania Guzman, Zenab Khan, James V. Parziale, Jennifer M. Debruyn, Nathan H. Lents

Publications and Research

Research on the human microbiome, the microbiota that live in, on, and around the human person, has revolutionized our understanding of the complex interactions between microbial life and human health and disease. The microbiome may also provide a valuable tool in forensic death investigations by helping to reveal the postmortem interval (PMI) of a decedent that is discovered after an unknown amount of time since death. Current methods of estimating PMI for cadavers discovered in uncontrolled, unstudied environments have substantial limitations, some of which may be overcome through the use of microbial indicators. In this project, we sampled the microbiomes …

Effective Teaching In The Eye Of Teacher Educators: A Case Study In A Higher Education, Melek Çakmak, Ülker Akkutay

The Qualitative Report

Attempts to explore teacher educators’ thoughts seem to be meaningful at educational sciences since the number of studies discussing effective teaching and effective teacher at teacher education in the eye of teacher educators are quite limited. Therefore, this study mainly aims to identify the viewpoints of teacher educators in order to discover how they contextualize the concept of effective teaching. For this aim, a case study design, increasingly used in education (Tellis, 1997), is utilized in the study. This method is suitable when the research addresses an explanatory question such as how or why? (Yin, 2004). A questionnaire including open-ended …

The Ribbed Drapery Of The Puerto Princesa Underground River (Palawan, Philippines): Morphology And Genesis, Paolo Forti, Giovanni Badino, Jose Maria Calaforra, Jo De Waele

International Journal of Speleology

During the 2011 speleological expedition to the Puerto Princesa Underground River (Palawan, Philippines) a drapery characterized by several close-to-horizontal ribs has been noticed. Even without sampling and analyzing its internal growth layers, a detailed morphological study allowed to present a possible genetic model. The presented model helps to explain its evolution, which is mainly controlled by variation in water flow as a consequence of the Palawan climate. When validated by further analyses, the same genetic mechanism could define also the evolution of the very common but still unexplained complex flowstones, which exhibit several close-to-horizontal steps, widenings and narrowings along their …

Today, hundreds fly in wingsuits, but flying remains a dangerous sport left to the select few We have the power to change that.

Adding The Influence Of A Shallow Water Table On Hydrology, Sediment And Pesticide Transport In A Vegetative Filter Strip Model : Development Of A Mechanistic Algorithm, Coupling, And Global Sensitivity Analysis To Evaluate This New Version Of The Open Source Model Vfsmod, Claire Lauvernet, Rafael Muñoz-Carpena, Nadia Carluer

Open Water Journal

A shallow water table can significantly affect soil infiltration and surface runoff during a rainfall event. Simple and robust models used as components of larger scale hydrological models are needed to analyze the impacts of shallow water table in the landscape. Salvucci and Entekhabi (1995) and Chu (1997) proposed an approximate non-uniform Green-Ampt time-implicit integral form solutions to the infiltration case for ponded soils bounded by a water table under initial hydrostatic equilibrium.

Trace Metal Transport Modeling Using Openmi: A Case Study Of Zenne River, Brussels Belgium, Chrismar Punzal, Narayan Kumar Shrestha, Olkeba Tolessa Leta, Bruno De Fraine, Ann Van Griensven, Marc Elskens, Willy Bauwens

Open Water Journal

In 2000, the European Water Framework Directive was developed, requiring a good ecological status for all surface waters in all member states by 2015 (EC, 2000). In order to achieve this, Environmental Quality Standards (EQS) for several substances and pollutants have been laid down (EC, 2008).

Since then, large investments were made for the management of the wastewaters of Brussels. This improved the water quality flowing into the river Zenne (Garnier et al., 2012). Despite these investments, the river still receives high loads of pollutants, especially considering the low discharge of the river and the water quality downstream from Brussels …

Packer, Javad Nazarian

Genomics and Precision Medicine Faculty Publications

Corticosteroids, such as dexamethasone, are routinely used as palliative care in neuro-oncology for their anti-inflammatory benefits, however many patients experience dose limiting side effects caused by glucocorticoid response element (GRE)-mediated transcription. The purpose of this study was to use a murine model to investigate a new steroid alternative, vamorolone, which promises to reduce side effects through dissociating GRE-mediated transcription and NF-κB -mediated anti-inflammatory actions. To compare vamorolone to dexamethasone in reducing pro-inflammatory signals in vitro, murine glioma cells were treated with dexamethasone, vamorolone or vehicle control. Changes in mRNA expression were assessed using the nanostring inflammatory platform. Furthermore, drug …

Overexpression Of Timp-3 In Chondrocytes Produces Transient Reduction In Growth Plate Length But Permanently Reduces Adult Bone Quality And Quantity, Blandine Poulet, Ke Liu, Darren A. Plumb, Phoung Vo, Mittal Shah, Katherine Ann Staines, Alexandra Sampson, Hiroyuke Nakamura, Hideaki Nagase, Alessandra Carriero, Sandra J. Shefelbine, Andrew A. Pitsillides, George Bou-Gharios

Biomedical Engineering and Sciences Faculty Publications

Bone development and length relies on the growth plate formation, which is dependent on degradative enzymes such as MMPs. Indeed, deletion of specific members of this enzyme family in mice results in important joint and bone abnormalities, suggesting a role in skeletal development. As such, the control of MMP activity is vital in the complex process of bone formation and growth. We generated a transgenic mouse line to overexpress TIMP3 in mouse chondrocytes using the Col2a1-chondrocyte promoter. This overexpression in cartilage resulted in a transient shortening of growth plate in homozygote mice but bone length was restored at eight weeks …

Manufacturing Consent In The Maghreb: How Mohammed Vi Of Morocco Survived The Arab Spring, David Michael Duke Ii

Dissertations and Theses

The Arab Spring of 2011 revealed stark variation in the durability of different types of authoritarian regimes. Kings and emirs demonstrably outperformed their republican peers. This paper provides a qualitative study of the Moroccan monarchy in order to better explain this pattern. The findings of an original media content analysis support the paper's thesis that Morocco's King Mohammed VI maintained his throne by effectively using a historically derived position of concentrated power and immense wealth to manipulate potential opposition and dominate public discourse. This multi-causal mechanism of manufactured consent helped create and sustain the monarch's domestic legitimacy while alienating his …

Myofilament Calcium Sensitivity: Consequences Of The Effective Concentration Of Troponin I, Jalal K. Siddiqui, Svetlana B. Tikunova, Shane D. Walton, Bin Liu, Meredith Meyer, Pieter P.

Control of calcium binding to and dissociation from cardiac troponin C (TnC) is essential to healthy cardiac muscle contraction/relaxation. There are numerous aberrant post-translational modifications and mutations within a plethora of contractile, and even non-contractile, proteins that appear to imbalance this delicate relationship. The direction and extent of the resulting change in calcium sensitivity is thought to drive the heart toward one type of disease or another. There are a number of molecular mechanisms that may be responsible for the altered calcium binding properties of TnC, potentially the most significant being the ability of the regulatory domain of TnC to …
