Hydraulic Geometry Curves In The Pee Dee Watershed, Z.T. Smoot, A.D. Jayakaran, D.R. Hitchcock

Journal of South Carolina Water Resources

Hydraulic bankfull geometry or regional curves are a useful metric for evaluating stream stability and planning stream restoration projects. Streams and tributaries within the Middle Pee Dee River Basin (MPDRB) in South Carolina drain an agrarian and forested landscape characterized by water conveyance structures, such as active and historical ditches which support forestry and agriculture. While streams in the region are generally stable, pockets of this landscape are beginning to face increasing pressure from development with signs of stream instability apparent in several locations as evidenced by streams in and around the urbanizing areas around Darlington and Florence, SC. In …

The Small Scatter Of The Baryonic Tully-Fisher Relation, Federico Lelli, Stacy S. Mcgaugh

Faculty Scholarship

In a Γ cold dark matter (ΓCDM) cosmology, the baryonic TullyFisher relation (BTFR) is expected to show significant intrinsic scatter resulting from the massconcentration relation of dark matter halos and the baryonic-tohalo mass ratio. We study the BTFR using a sample of 118 disk galaxies (spirals and irregulars) with data of the highest quality: extended H I rotation curves (tracing the outer velocity) and Spitzer photometry at 3.6 μm (tracing the stellar mass). Assuming that the stellar mass-to-light ratio (Υ∗) is nearly constant at 3.6 μm, we find that the scatter, slope, and normalization of the BTFR systematically vary with …

Test Of Target Independence For Free-Free Scattering In A Nd:Yag Laser Field, Nicholas L. S. Martin, B. A. Deharak

Physics and Astronomy Faculty Publications

We report measurements of one-, two-, and three-photon processes during the elastic scattering of electrons through 90^∘ by helium, argon, and molecular-nitrogen targets, in the presence of 1.17-eV photons from a Nd:YAG laser. The incident energy of the electrons was 200 and 350 eV, and the linear polarization direction of the laser was parallel to the momentum transfer direction. Our measured free-free count rates for the three processes are target independent within the experimental uncertainties, perfectly consistent with the Kroll-Watson approximation, which assumes no interaction of the laser radiation with the target.

Pore Structure And Synergy In Antimicrobial Peptides Of The Magainin Family, Almudena Pino-Angeles, John M. Leveritt Iii, Themis Lazaridis

Publications and Research

Magainin 2 and PGLa are among the best-studied cationic antimicrobial peptides. They bind preferentially to negatively charged membranes and apparently cause their disruption by the formation of transmembrane pores, whose detailed structure is still unclear. Here we report the results of 5–9 μs all-atom molecular dynamics simulations starting from tetrameric transmembrane helical bundles of these two peptides, as well as their stoichiometric mixture, and the analog MG-H2 in DMPC or 3:1 DMPC/DMPG membranes. The simulations produce pore structures that appear converged, although some effect of the starting peptide arrangement (parallel vs. antiparallel) is still observed on this timescale. The peptides …

Fortilin Potentiates The Peroxidase Activity Of Peroxiredoxin-1 And Protects Against Alcohol-Induced Liver Damage In Mice, Owen M. Mcdougal

Chemistry and Biochemistry Faculty Publications and Presentations

Fortilin, a pro-survival molecule, inhibits p53-induced apoptosis by binding to the sequence-specific DNA-binding domain of the tumor suppressor protein and preventing it from transcriptionally activating Bax. Intriguingly, fortilin protects cells against ROS-induced cell death, independent of p53. The signaling pathway through which fortilin protects cells against ROS-induced cell death, however, is unknown. Here we report that fortilin physically interacts with the antioxidant enzyme peroxiredoxin-1 (PRX1), protects it from proteasome-mediated degradation, and keeps it enzymatically active by blocking its deactivating phosphorylation by Mst1, a serine/threonine kinase. At the whole animal level, the liver-specific overexpression of fortilin reduced PRX1 phosphorylation in the …

Simulating Magnetospheres With Numerical Relativity: The Giraffe Code, Maria Babiuc-Hamilton

Physics Faculty Research

Numerical Relativity is successful in the simulation of black holes and gravitational waves. In recent years, teams have tackled the problem of the interaction of gravitational and electromagnetic waves. We developed a new code for the numerical simulation of neutron and black hole magnetospheres, using the FFE formalism. We tested the performance of the new code named GiRaFFE, in 1D and 3D test suits. We will study magnetospheres, focusing on jets by the Blandford -Znajek mechanism.

Respecting Anatomically Rigid Regions In Nonrigid Registration, Eric J. Spangler

Theses

Medical image registration has received considerable attention in the medical imaging and computer vision communities because of the variety of ways in which it can potentially improve patient care. This application of image registration aligns images of regions of the human body for comparing images of the same patient at different times, for example, when assessing differences in a disease over time; comparing images of the same anatomical structure across different patients, for example, to understand patient variability; and comparing images of the same patient from different modalities that provide complementary information, for example, CT and PET to assess cancer. …

Distributed Attribute Based Access Control Of Aggregated Data In Sensor Clouds, Vimal Kumar, Sanjay Kumar Madria

Computer Science Faculty Research & Creative Works

Sensor clouds are large scale wireless sensor networks (WSNs), built by connecting a number of smaller WSNs together. Each of these smaller individual WSNs may be owned by different owners. Sensor clouds are dynamic in nature, where wireless sensors can be provisioned and de-provisioned for the users on demand. In such a multi-user, multi-owner system, user access control is a significant problem. Previous user access control schemes have been centralized and designed for standalone sensors or smaller networks and do not take large networks into consideration. In large networks, data is generally aggregated in-network during data collection. In this paper, …

Surficial Geology And Provenance Of Glacial Deposits Of The Saybrook 7.5 Minute Quadrangle, Mclean County, Illinois, Ellyn S. Rickels

Theses and Dissertations

The glaciated landscape of much of Illinois is a product of the most recent glacial episode, which is characterized by a series of end moraines composed predominantly of till and deposited by ice flowing into Illinois from the east and northeast around 20,000 years before present time. Two separate projects were completed as part of this thesis to better understand the surficial geology and the source areas of glacial sediment in central Illinois: the creation of a surficial geologic map of the Saybrook 7.5 Minute Quadrangle and a provenance study of granitic clasts from two moraines in the area.

Online Novelty Detection System: One-Class Classification Of Systemic Operation, Ryan M. Bowen

Theses

Presented is an Online Novelty Detection System (ONDS) that uses Gaussian Mixture Models (GMMs) and one-class classification techniques to identify novel information from multivariate times-series data. Multiple data preprocessing methods are explored and features vectors formed from frequency components obtained by the Fast Fourier Transform (FFT) and Welch's method of estimating Power Spectral Density (PSD). The number of features are reduced by using bandpower schemes and Principal Component Analysis (PCA). The Expectation Maximization (EM) algorithm is used to learn parameters for GMMs on feature vectors collected from only normal operational conditions. One-class classification is achieved by thresholding likelihood values relative …

Jainism And Nonviolence: From Mahavira To Modern Times, Lana E. Sims

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

The research contained in this paper focuses on the religion of Jainism, its main principle of ahimsa, or nonviolence, and how that philosophy has evolved over the years, eventually inspiring today’s nonviolent movements. First, a look will be taken at the origin of Jainism, with a brief explanation of its most important principles and beliefs. Then, ahimsa is explained as it has been traditionally perceived by Jains. The recent evolution of the meaning of ahimsa and its impact on modern nonviolence movements is discussed, with a focus on the influence of second-generation Jains in the United States on the …

How Much A Quarter Cost: Allegory Of A Coin And Other Stories, Grant C. Gallo

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

The philosophical theories of Baruch Spinoza and George Berkley were described, compared, and contrasted. Various examples and metaphors were used to help fully illustrate their respective metaphysical, epistemological, and ethical positions. The relevance of their theories to current philosophical discourse was discussed; showing that even in today’s technologically advanced society, seemingly antiquated ideas may still provide useful knowledge. In the end, Spinoza and Berkley’s apparently conflicting paradigms are rectified through a multiplexual, relativistic lens.

Ancient Animal Ethics: The Earliest Arguments For The Ethical Consideration Of Nonhuman Animals, Joshua J. Sias

The Downtown Review: An Interdisciplinary Journal Written and Peer-Reviewed by Mandel Honors College Students at Cleveland State University

Primarily focused on the ancient Greek philosophers, this work offers a survey of the earliest arguments for and against the inclusion of nonhuman animals in human realms of ethical consideration. By following the trends of ancient western thought concerning animal ethics, the influencing factors behind the downfall of the subject in Medieval times, both in terms of discourse and practice, is discovered in the philosophical exchange that preceded medieval thought.

Limiting The Impact Of Destructive Analytical Techniques Through Sequential Microspatial Sampling Of The Enamel From Single Teeth, Alexis E. Dolphin, Mathew A. Teeter, Christine D. White, Fred J. Longstaffe

Earth Sciences Publications

A fundamental research concern within contemporary bioarchaeology is the sensitive balance between the preservation of human remains and the use of destructive techniques to collect information. Here we describe one example of how multiple microspatial destructive/semi-destructive techniques may be carried out in sequence using only the enamel of a single tooth. With careful planning of both sample preparation strategies and sequencing of sampling methods, it is possible to produce multiple datasets, and yet to retain material for future analyses.

In this case, enamel from the teeth of 27 individuals who lived during the early medieval period (AD 1170-1198) in Bergen, …

Equilibrium Fluctuations In A Metastable State Of A Ginzburg–Landau System, D.I. Uzunov, Alexander Umantsev

College of Health, Science, and Technology

We calculate thermal fluctuation properties – volume-averaged order parameter, Helmholtz free and internal energies, and their variances – of a supersaturated disordered phase in the Gibbs canonical ensemble for an asymmetric (third-order interactions), athermal (independence of the supersaturation and thermal noise) effective Hamiltonian. These properties are different from those of the symmetric thermal one with the most important differences being the phase coexistence and ‘thermal expansion’. The fluctuation properties of the system were calculated theoretically, using the perturbation method, and numerically, using the ‘brute force’ simulations method. Overall, the numerical calculations match the theory within the accuracy of the numerical …

Atypical Visual And Somatosensory Adaptation In Schizophrenia-Spectrum Disorders, Gizely Andrade, John Butler, Gregory Peter, Sophie Molholm, John J. Foxe

Articles

Neurophysiological investigations in patients with schizophrenia consistently show early sensory processing deficits in the visual system. Importantly, comparable sensory deficits have also been established in healthy first-degree biological relatives of patients with schizophrenia and in first-episode drug-naive patients. The clear implication is that these measures are endophenotypic, related to the underlying genetic liability for schizophrenia. However, there is significant overlap between patient response distributions and those of healthy individuals without affected first-degree relatives. Here we sought to develop more sensitive measures of sensory dysfunction in this population, with an eye to establishing endophenotypic markers with better predictive capabilities. We used …

Ocular Drift Along The Mental Number Line., A Myachykov, R Ellis, A Cangelosi, Mh Fischer

School of Psychology

We examined the spontaneous association between numbers and space by documenting attention deployment and the time course of associated spatial-numerical mapping with and without overt oculomotor responses. In Experiment 1, participants maintained central fixation while listening to number names. In Experiment 2, they made horizontal target-direct saccades following auditory number presentation. In both experiments, we continuously measured spontaneous ocular drift in horizontal space during and after number presentation. Experiment 2 also measured visual-probe-directed saccades following number presentation. Reliable ocular drift congruent with a horizontal mental number line emerged during and after number presentation in both experiments. Our results provide new …

Formalizing And Verifying Stochastic System Architectures Using Monterey Phoenix, Songzheng Song, Jiexin Zhang, Yang Liu, Mikhail Auguston, Jun Sun, Jin Song Dong, Tieming Chen

Research Collection School Of Computing and Information Systems

The analysis of software architecture plays an important role in understanding the system structures and facilitate proper implementation of user requirements. Despite its importance in the software engineering practice, the lack of formal description and verification support in this domain hinders the development of quality architectural models. To tackle this problem, in this work, we develop an approach for modeling and verifying software architectures specified using Monterey Phoenix (MP) architecture description language. MP is capable of modeling system and environment behaviors based on event traces, as well as supporting different architecture composition operations and views. First, we formalize the syntax …
