Implications Of The Modifiable Areal Unit Problem For Wildfire Analyses, Timothy P. Nagle-Mcnaughton, Xi Gong, Jose A. Constantine

Geography and Environmental Studies Faculty Publications

Wildfires pose a danger to both ecologies and communities. To this end, many large-scale analyses of wildfire patterns and behavior rely on the aggregation of point data to polygons, typically those based on distinct disparate ecological areas. However, the sizes, shapes, andorientations of the polygons to which data are aggregated are not neutral factors in the resulting analysis. The influence of the aggregation polygons on calculated results is known as the modifiable areal unit problem (MAUP), which is well-documented in the spatial statistics literature. Despite the documentation of the MAUP, relatively few wildfire studies consider the effects of the MAUP …

From Field To Film: Mosquito Surveillance And Survey Of Us Adults' Knowledge And Attitudes Towards Arthropod-Borne Disease Vectors, Justine Laviolette

Department of Entomology: Dissertations, Theses, and Student Research

Mosquito-borne disease is a public health challenge that warrants an active surveillance program for the identification of mosquito populations and the education of the public for prevention and protection against disease-transmitting arthropods. The communication of science to the public is necessary to prevent disease, change behavior, and promote a dialog between scientists and the public.

Systematic Computational Identification Of Prognostic Cytogenetic Markers In Neuroblastoma, Chao Qin, Xiaoyan He, Yanding Zhao, Chun Yip Tong, Kenneth Y. Zhu, Yongqi Sun, Chao Cheng

Dartmouth Scholarship

Background: Neuroblastoma (NB) is the most common extracranial solid tumor found in children. The frequent gain/loss of many chromosome bands in tumor cells and absence of mutations found at diagnosis suggests that NB is a copy number-driven cancer. Despite the previous work, a systematic analysis that investigates the relationship between such frequent gain/loss of chromosome bands and patient prognosis has yet to be implemented. Methods: First, we analyzed two NB CNV datasets to select chromosomal bands with a high frequency of gain or loss. Second, we applied a computational approach to infer sample-specific CNVs for each chromosomal band selected in …

Simulation Study On Aerodynamic Characteristics Of Flapping-Wing Aircraft With Multi-Stage Wing And Multiple Degree Of Freedom, Yonggang Yang, Xindong Gu

Journal of System Simulation

Abstract: In the traditonal flapping-wing aircraft model, most of the wings are two-dimensional rigid wings, and the upswing and downwing processes are completely symmetrical. In order to further improve the aerodynamic characteristics of the flapping-wing aircraft, this paper uses the idea of approximate flexibility to establish the multi-stage wing to achieve the approximate flexibility effect. At the same time, the rapid return characteristic is added to prolong the down-flapping time. And a three-dimensional model of “flutter-twist-bend folding” is proposed by adding the bending-folding motion on the basis of the original movement and twisting motion. The model is imported into Xflow …

Distinct Roles Of Interferon Alpha And Beta In Controlling Chikungunya Virus Replication And Modulating Neutrophil-Mediated Inflammation, Lindsey E Cook, Marissa C Locke, Alissa R Young, Kristen Monte, Matthew L Hedberg, Raeann M Shimak, Kathleen C F Sheehan, Deborah J Veis, Michael S Diamond, Deborah J Lenschow

Open Access Publications

Type I interferons (IFNs) are key mediators of the innate immune response. Although members of this family of cytokines signal through a single shared receptor, biochemical and functional variation exists in response to different IFN subtypes. While previous work has demonstrated that type I IFNs are essential to control infection by chikungunya virus (CHIKV), a globally emerging alphavirus, the contributions of individual IFN subtypes remain undefined. To address this question, we evaluated CHIKV pathogenesis in mice lacking IFN-β (IFN-β knockout [IFN-β-KO] mice or mice treated with an IFN-β-blocking antibody) or IFN-α (IFN regulatory factor 7 knockout [IRF7-KO] mice or mice …

Localized Dielectric Loss Heating In Dielectrophoresis Devices, Tae Joon Kwak, Imtiaz Hossen, Rashid Bashir, Woo-Jin Chang, Chung-Hoon Lee

Electrical and Computer Engineering Faculty Research and Publications

Temperature increases during dielectrophoresis (DEP) can affect the response of biological entities, and ignoring the effect can result in misleading analysis. The heating mechanism of a DEP device is typically considered to be the result of Joule heating and is overlooked without an appropriate analysis. Our experiment and analysis indicate that the heating mechanism is due to the dielectric loss (Debye relaxation). A temperature increase between interdigitated electrodes (IDEs) has been measured with an integrated micro temperature sensor between IDEs to be as high as 70 °C at 1.5 MHz with a 30 V_pp applied voltage to our ultra-low …

Distinct Vip And Pacap Functions In The Distal Nerve Stump During Peripheral Nerve Regeneration, Patricia K. Woodley, Qing Min, Yankun Li, Nina F. Mulvey, David B. Parkinson, Xin Peng Dun

Peninsula Medical School

Vasoactive Intestinal Peptide (VIP) and Pituitary Adenylyl Cyclase Activating Peptide (PACAP) are regeneration-associated neuropeptides, which are up-regulated by neurons following peripheral nerve injury. So far, they have only been studied for their roles as autocrine signals for both neuronal survival and axon outgrowth during peripheral nerve regeneration. In this report, we examined VIP and PACAP’s paracrine effects on Schwann cells and macrophages in the distal nerve stump during peripheral nerve regeneration. We show that VPAC1, VPAC2, and PAC1 are all up-regulated in the mouse distal nerve following peripheral nerve injury and are highly expressed in Schwann cells and macrophages within …

Fish Assemblages Of The Withlacoochee River Basin In South Georgia, Usa, Matthew J. Cannister, David L. Bechler

Georgia Journal of Science

An ichthyofauna review of literature prior to 2008 on the Withlacoochee River basin in south-central Georgia, USA, indicated that the fish fauna was underrepresented compared to other rivers, such as the Suwannee River basin in Florida of which the Withlacoochee River is a tributary. A survey would provide the state of Georgia potentially valuable additional information on the fish fauna within the basin. A 45-site survey within the eastern portion of the Withlacoochee River basin was conducted from 2008 to 2010 employing seines, gill nets, fish traps, trotlines, and creel surveys. Surveys yielded 51 fish species of which three, the …

Post-Traumatic Stress Disorder In Veterans Returning From Combat: Impact On Social Reintegration, Rod Van Pelt

Purdue Undergraduate Research Conference

Post-traumatic stress disorder (PTSD) is a mental health condition frequently observed in soldiers and veterans.The reintegration of veterans returning from combat is a challenge that state and federal administrations, as well as civilian structures and workplaces, face routinely. Despite PTSD being a public health issue with a socioeconomic impact, non-scholarly debate is the primary source of information on the non-medical burden of PTSD. The majority of scholarly evidence focuses on PTSD primarily as a medical condition, including when addressing the problem from a socioeconomic standpoint. In fact, most of the recent scholarly evidence points to specific areas of PTSD, such …

The Diverse Roles Of Mitochondrial Dynamics In Retinal Ganglion Cell Maturation, Disease, And Regeneration, Alexander Kreymerman

Open Access Dissertations

Mitochondria maintain a diversity of roles central to the array of neuronal functions and survival, as implied by the ubiquitous evidence of mitochondrial roles in neuronal developmental, aging, and disease progression. The canonical function of mitochondria is to produce ATP, a critical and dominant molecule used by cells for energy requiring activities. However, since their discovery more than a century ago, mitochondria have been implicated in a vast collection of cellular processes, largely driven by their expanded function beyond metabolism, including secondary messenger signaling, cytoplasmic Ca2+ signaling, fatty acid oxidation, reactive oxygen species (ROS) production, and protein scaffolding. More recently, …

A Comprehensive Investigation Of Mth1 As A Novel Therapeutic Target In Ras-Driven Cancers., Govindi Jayanika De Alwis Samaranayake

Open Access Dissertations

The nucleotide pool is significantly more susceptible to oxidative damage induced by reactive oxygen species (ROS) compared to genomic DNA, due to DNA being more protected by the double helix and nucleosome packing. The NUDIX pyrophosphatase, MutT Homolog 1 (MTH1), maintains nucleotide pool integrity by hydrolyzing oxidized purines thus preventing their genomic incorporation. If incorporated into DNA the accumulation of these oxidized purines can lead to DNA strand breaks, genomic instability, and ultimately cell death. Our prior work has shown that MTH1 is critical in facilitating multiple pro-tumorigenic phenotypes in oncogenic RAS-mutated cancer cells, with its depletion leading to decreased …
