Identification Of Key Proteins In Human Epithelial Cells Responding To Bystander Signals From Irradiated Trout Skin, Hayley Furlong, Richard Smith, Jiaxi Wang, Colin Seymour, Carmel Mothersill, Orla L. Howe

Articles

Radiation-induced bystander signaling has been found to occur in live rainbow trout fish (Oncorhynchus mykiss). This article reports identification of key proteomic changes in a bystander reporter cell line (HaCaT) grown in low-dose irradiated tissue-conditioned media (ITCM) from rainbow trout fish. In vitro explant cultures were generated from the skin of fish previously exposed to low doses (0.1 and 0.5 Gy) of X-ray radiation in vivo. The ITCM was harvested from all donor explant cultures and placed on recipient HaCaT cells to observe any change in protein expression caused by the bystander signals. Proteomic methods using 2-dimensional (2D) gel electrophoresis …

Searching For Stochastic Gravitational Waves Using Data From The Two Colocated Ligo Hanford Detectors, J. Aasi, Marco Cavaglia, For Full List Of Authors, See Publisher's Website.

Physics Faculty Research & Creative Works

Searches for a stochastic gravitational-wave background (SGWB) using terrestrial detectors typically involve cross-correlating data from pairs of detectors. The sensitivity of such cross-correlation analyses depends, among other things, on the separation between the two detectors: the smaller the separation, the better the sensitivity. Hence, a colocated detector pair is more sensitive to a gravitational-wave background than a noncolocated detector pair. However, colocated detectors are also expected to suffer from correlated noise from instrumental and environmental effects that could contaminate the measurement of the background. Hence, methods to identify and mitigate the effects of correlated noise are necessary to achieve the …

Biblical Literalism And The Acceptance Of Biological Evolution In Christian University Students, Heather N. Chamberlain

Dissertations and Theses @ UNI

Is it possible to accept biological evolution without rejecting God? Understanding student perspectives about religious belief and biological evolution is important to effectively teach science. There are many factors in this complex relationship and this study explored three: differences in Christian denominations, interpretation of scripture, and perspectives of the relationship between religious belief with acceptance of evolution. The participants were freshman elementary education majors at a Midwest university who completed a questionnaire about religious beliefs and the Inventory of Student Evolution Acceptance (I-SEA).

The results indicated no significant difference between Christian denomination and acceptance of evolution. Participants who took the …

Dispersion Characteristics Analysis Of One Dimensional Multiple Periodic Structures And Their Applications To Antennas, Zi Long Ma, Li (Lijun) Jun Jiang, Shulabh Gupta, Wei E.I. Sha

Electrical and Computer Engineering Faculty Research & Creative Works

This paper proposes a general characterization of one dimensional multiple periodic (MP) structures for electromagnetic transmission and radiation. Studies are conducted from three aspects: Firstly, the dispersion relations of non-dispersive (conventional) and dispersive (composite right/left-handed (CRLH)) materials are analyzed. Regarding each category of materials, detailed analyses for distributed layered media and lumped circuits are presented. Through studies, we found that the periodicity increase opens up multiple stopbands. According to our physical explanations and numerical results, the relation between stopbands and periodicity is clarified. Additionally, the periodicity increase also reduces the separation distance of space harmonic modes along the phase constant …

Low Complexity Polynomial Expansion Detector For Massive Mimo Uplink With Multiple-Antenna Users, An An Lu, Xiqi Gao, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a low complexity polynomial expansion (PE) detector for massive multi-input multi-output (MIMO) uplink transmissions is proposed. In contrast to most massive MIMO systems in the literature, where single-antenna user equipment's (UEs) are assumed, multiple-antenna UEs are employed in this paper. Furthermore, each link between a user and the base station forms a jointly correlated Rician fading channel. The PE detector reduces the complexity of the minimum mean square error (MMSE) detector by replacing the matrix inversion with an approximate matrix polynomial. In the design of the low complexity PE detector, the approximations of the moments of the …

A Framework To Improve A Nation's Competitiveness Through Quality Awards And Performance Improvement Tools, Amr Alamri

Wayne State University Dissertations

Each country, represented by its government, aims to serve its citizens better. This is achieved by better utilization of resources and higher productivity. The ability to do so will lead to a competitive nation. Recently, countries were able to compare themselves in terms of competitiveness using international indexes and references. These references gave countries a benchmark to know where they exist compared to other nations. They help governments to understand their strengths and weaknesses within the competitiveness components. However, nations differ in the actions which are to be taken in order to improve their competitiveness. Governments establish and regulate many …

Object Tracking: Appearance Modeling And Feature Learning, Raed Almomani

Wayne State University Dissertations

Object tracking in real scenes is an important problem in computer vision due to increasing usage of tracking systems day in and day out in various applications such as surveillance, security, monitoring and robotic vision. Object tracking is the process of locating objects of interest in every frame of video frames. Many systems have been proposed to address the tracking problem where the major challenges come from handling appearance variation during tracking caused by changing scale, pose, rotation, illumination and occlusion.

In this dissertation, we address these challenges by introducing several novel tracking techniques. First, we developed a multiple object …

An Argument For A Neutral Free Logic, Daniel Yeakel

Wayne State University Dissertations

I argue for a neutral free logic is a logic wherein sentences containing non-referring terms do not have truth value. The primary support for this conclusion comes by way of criticism of the alternatives. If every sentence of the form `a = a' is a logical truth and is consequently knowable a priori then it will follow absurdly that `a exists' is knowable a priori. There are several alternatives for avoiding this intolerable conclusion and I argue that, with the exception of neutral free logic which holds that `a = a' can lack truth value, their successes are not sufficient …

A Control-Theoretic Design And Analysis Framework For Resilient Hard Real-Time Systems, Pradeep Mahendra Hettiarachchi

Wayne State University Dissertations

We introduce a new design metric called system-resiliency which characterizes the maximum unpredictable

external stresses that any hard-real-time performance mode can withstand. Our proposed systemresiliency

framework addresses resiliency determination for real-time systems with physical and hardware

limitations. Furthermore, our framework advises the system designer about the feasible trade-offs between

external system resources for the system operating modes on a real-time system that operates in a

multi-parametric resiliency environment.

Modern multi-modal real-time systems degrade the system’s operational modes as a response to unpredictable

external stimuli. During these mode transitions, real-time systems should demonstrate a reliable

and graceful degradation of service. Many …

Well-Posedness Properties In Variational Analysis And Its Applications, Wei Ouyang

Wayne State University Dissertations

This dissertation focuses on the study and applications of some significant properties in well-posedness and sensitivity analysis, among which the notions of uniform metric regularity , higher-order metric subregularity and its strong subregularity counterpart play an essential role in modern variational analysis. We derived verifiable sufficient conditions and necessary conditions for those notions in terms of appropriate generalized differential as well as geometric constructions of variational analysis. Concrete examples are provided to illustrate the behavior and compare the results. Optimality conditions of parametric variational systems (PVS) under equilibrium constraints are also investigated via the terms of coderivatives. We derived necessary …

Saliency-Guided Color-To-Gray Conversion Using Region-Based Optimization, Hao Du, Shengfeng He, Bin Sheng, Lizhuang Ma, Rynson W.H. Lau

Research Collection School Of Computing and Information Systems

Image decolorization is a fundamental problem for many real-world applications, including monochrome printing and photograph rendering. In this paper, we propose a new color-to-gray conversion method that is based on a region-based saliency model. First, we construct a parametric color-to-gray mapping function based on global color information as well as local contrast. Second, we propose a region-based saliency model that computes visual contrast among pixel regions. Third, we minimize the salience difference between the original color image and the output grayscale image in order to preserve contrast discrimination. To evaluate the performance of the proposed method in preserving contrast in …

Glaucoma is the main cause of irreversible blindness worldwide. This disease is characterized by apoptosis of retinal ganglion cells (RGC) and visual field loss that seems to be related to elevated intraocular pressure (IOP). Several lines of evidences have implicated the crucial role of mitochondrial dysfunction in the pathogenesis of glaucoma. Increased mitochondrial oxidative stress in RGC may underlie or contribute to susceptibility of RGC to apoptosis. In our work we (i) designed a rabbit model of chronic, moderately elevated IOP for studying glaucoma and (ii) demonstrated efficacy of mitochondria- Targeted antioxidant SkQ1 as a tool to reverse several traits …

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Sedimentological and stratigraphic studies of seven stratigraphic sections of Permian Hongyanchi (HYC) and Quanzijie (QZJ) low-order cycles (LCs) in the Tarlong-Taodonggou half graben and Dalongkou area in Bogda Mountains, NW China, demonstrate effective approaches and methodology in cyclo- and time-stratigraphic analyses of complex fluvial-lacustrine deposits in an intracontinental rift setting. A new synchronous stratigraphic unit, the lower QZJ LC is defined. The lower and upper boundaries of this cycle include a regionally correlative disconformity, erosional unconformity, and conformity, across which significant and abrupt changes in palaeoenvironments and tectonic and climatic conditions occurred. The lower boundary is an erosional unconformity and …

Algorithm Selection Via Ranking, Jayadi Oentaryo Richard, Handoko Stephanus Daniel, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

The abundance of algorithms developed to solve different problems has given rise to an important research question: How do we choose the best algorithm for a given problem? Known as algorithm selection, this issue has been prevailing in many domains, as no single algorithm can perform best on all problem instances. Traditional algorithm selection and portfolio construction methods typically treat the problem as a classification or regression task. In this paper, we present a new approach that provides a more natural treatment of algorithm selection and portfolio construction as a ranking task. Accordingly, we develop a Ranking-Based Algorithm Selection (RAS) …

The Value Of Soft Variables In Corporate Reorganizations, Michelle M. Harner

Faculty Scholarship

When a company is worth more as a going concern than on a liquidation basis, what creates that additional value? Is it the people, management decisions, the simple synergies of the operating business, or some combination of these types of soft variables? And perhaps more importantly, who owns or has an interest in these soft variables? This article explores these questions under existing legal doctrine and practice norms. Specifically, it discusses the characterization of soft variables under applicable law and in financing documents, and it surveys related judicial decisions. It also considers the overarching public policy and Constitutional implications of …

Assessing Risks In Insulation Retrofits Using Hygrothermal Software Tools, Joseph Little, Calina Ferrari, Beñat Arregi

Reports

The greatest difference between buildings of traditional and non-traditional construction design lies not so much in the building materials used, but in the way they are used to construct the external envelope of a building – in the way they are assembled. One may say that the defining approach of traditional construction is the management of moisture and, in contrast, one can say that modern construction systems generally (but not always) depend on blocking, not managing, moisture. The deterioration and decay that occurs in buildings almost always involves moisture. Three relevant moisture sources are identified in this report: indoor vapour, …

From ‘Sots-Romanticism’ To Rom-Com: The Strugatskys’ Monday Begins On Saturday As A Film Comedy, Yvonne Howell

Languages, Literatures, and Cultures Faculty Publications

The Strugatskii brothers’ novella Ponedel’nik nachinaetsia v subbotu (Monday Begins on Saturday; 1965) imagines bright young scientists working at the cutting edge between quantum physics and folktale sorcery in a setting that was undeniably contemporary and local. I argue that the story can be best understood as ‘soc(ialist) romanticism’ – an aesthetic mode that celebrates the possibilities for individual questing and agency in late Soviet socialism. Konstantin Bromberg’s 1982 adaptation of the Strugatskiis’s story abandons both the romanticism and complexity of the novella, but, by incorporating elements of the‘youth film’, it represents a different kind of Soviet rom-com.

Electrical Resistivity Imaging For Long-Term Autonomous Monitoring Of Hydrocarbon Degradation: Lessons From The Deepwater Horizon Oil Spill, Jeffrey W. Heenan, Lee D. Slater, Dimitrios Ntarlagiannis, Estella A. Atekwana, Babu Z. Fathepure, Sonal Dalvi, Cameron Ross, D. Dale Werkema, Eliot A. Atekwana

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

Conceptual models for the geophysical responses associated with hydrocarbon degradation suggest that the long-term evolution of an oil plume will result in a more conductive anomaly than the initial contamination. In response to the Deepwater Horizon (DH) oil spill into the Gulf of Mexico in 2010, an autonomous resistivity monitoring system was deployed on Grand Terre, Louisiana, in an attempt to monitor natural degradation processes in hydrocarbon-impacted beach sediments of this island. A 48-electrode surface array with a 0.5-m spacing was installed to obtain twice-daily images of the resistivity structure of the shallow subsurface impacted by oil. Over the course …

Elastic Personalized Nonfunctional Attribute Preference And Trade-Off Based Service Selection, Kenneth K. Fletcher, Xiaoqing F. Liu, Mingdong Tang

Computer Science Faculty Research & Creative Works

For service users to get the best service that meet their requirements, they prefer to personalize their nonfunctional attributes, such as reliability and price. However, the personalization makes it challenging for service providers to completely meet users' preferences, because they have to deal with conflicting nonfunctional attributes when selecting services for users. With this in mind, users may sometimes want to explicitly specify their trade-offs among nonfunctional attributes to make their preferences known to service providers. In this article, we present a novel service selection method based on fuzzy logic that considers users' personalized preferences and their trade-offs on nonfunctional …

Boron Nitride Colloidal Solutions, Ultralight Aerogels And Freestanding Membranes Through One-Step Exfoliation And Functionalization, Weiwei Lei, Vadym Mochalin, Dan Liu, Si Qin, Yury G. Gogotsi, Ying Chen

Chemistry Faculty Research & Creative Works

Manufacturing of aerogels and membranes from hexagonal boron nitride (h-BN) is much more difficult than from graphene or graphene oxides because of the poor dispersibility of h-BN in water, which limits its exfoliation and preparation of colloidal solutions. Here, a simple, one-step mechano-chemical process to exfoliate and functionalize h-BN into highly water-dispersible, few-layer h-BN containing amino groups is presented. The colloidal solutions of few-layer h-BN can have unprecedentedly high concentrations, up to 30 mg ml^-1, and are stable for up to several months. They can be used to produce ultralight aerogels with a density of 1.4 mg cm …

Outlier detection is a well-studied problem in various fields. The unique characteristics and constraints of wireless sensor networks (WSN) make this problem especially challenging. Sensors can detect outliers for a plethora of reasons and these reasons need to be inferred in real time. Here, we survey the current state of research in this area, compare them and present some future directions for smarter handling of outliers in WSN.

Privacy Policy Inference Of User-Uploaded Images On Content Sharing Sites, Anna Cinzia Squicciarini, Dan Lin, Smitha Sundareswaran, Joshua Wede

Computer Science Faculty Research & Creative Works

With the increasing volume of images users share through social sites, maintaining privacy has become a major problem, as demonstrated by a recent wave of publicized incidents where users inadvertently shared personal information. In light of these incidents, the need of tools to help users control access to their shared content is apparent. Toward addressing this need, we propose an Adaptive Privacy Policy Prediction (A3P) system to help users compose privacy settings for their images. We examine the role of social context, image content, and metadata as possible indicators of users' privacy preferences. We propose a two-level framework which according …

Properly Colored Notions Of Connectivity - A Dynamic Survey, Xueliang Li, Colton Magnant

Mathematical Sciences: Faculty Publications

Sheehan conjectured in 1975 that every Hamiltonian regular simple graph of even degree at least four contains a second Hamiltonian cycle. We prove that most claw-free Hamiltonian graphs with minimum degree at least 3 have a second Hamiltonian cycle and describe the structure of those graphs not covered by our result. By this result, we show that Sheehan’s conjecture holds for claw-free graphs whose order is not divisible by 6. In addition, we believe that the structure that we introduce can be useful for further studies on claw-free graphs.
