A Study Of Catalytic Microcombustion For A Portable Power Supply Device, Bhanuprakash Reddy Guggilla

Theses and Dissertations

The essential need for portable and dense power sources has been greatly increased with the prevalence of portable electronic devices in the past decade. Catalytic combustion of hydrocarbon and oxygenated fuels has the potential to provide an alternative power source for portable electronic devices by replacing relatively today's heavy battery technology. A successful self-ignition and sustainable catalyst combustion for a variety of fuels using Platinum (Pt)-impregnated substrate was demonstrated in our previous work.

Present work explores the performance of a microcombustion thermoelectric coupled (MTC) device with improved reactor configuration design. Chemically synthesized platinum nanoparticles with particle diameters of approx. 8 …

Global Epidemiology Of Lung Cancer., Julie A. Barta, Md, Charles A. Powell, Juan P. Wisnivesky

Division of Pulmonary, Allergy, and Critical Care Medicine Faculty Papers

While lung cancer has been the leading cause of cancer-related deaths for many years in the United States, incidence and mortality statistics - among other measures - vary widely worldwide. The aim of this study was to review the evidence on lung cancer epidemiology, including data of international scope with comparisons of economically, socially, and biologically different patient groups. In industrialized nations, evolving social and cultural smoking patterns have led to rising or plateauing rates of lung cancer in women, lagging the long-declining smoking and cancer incidence rates in men. In contrast, emerging economies vary widely in smoking practices and …

Community-Engaged Teaching: Lessons From A Participatory History Project, Amie Thurber, Sarah V. Suiter

School of Social Work Faculty Publications and Presentations

How can we create opportunities for students to gain experience in community-engaged scholarship that truly benefits the community given the constraints of the academic calendar, students’ varied capacity to develop reciprocal and responsive community relationships, and the tendency for community-engaged research to instrumentalize community partners in service to academic deliverables? This paper explores one attempt to meet this challenge: an experimental graduate course in community development that linked course content to a participatory history project. Designed as a Scholarship of Teaching and Learning (SoTL) study, instructors studied the instructional process as well as outcomes for students and community partners. We …

Takeoff Temperatures In Melitaea Cinxia Butterflies From Latitudinal And Elevational Range Limits: A Potential Adaptation To Solar Irradiance, C Parmesan, M Singer, N Advani

School of Biological and Marine Sciences

1. This study provides evidence that a heliophilic butterfly, the Glanville fritillary (Melitaea cinxia) has adapted differently to environmental variation across latitudes and elevations. 2. In cool air, basking M. cinxia orient themselves perpendicular to the sun's rays to gain heat and take off. During flight, solar heating is reduced because orientation perpendicular to the sun is no longer possible and convective cooling occurs. Consequently, M. cinxia have been shown to suffer net heat loss in flight, even in full sunshine. When flight duration is restricted in this way, the takeoff temperature becomes an important thermal adaptation. 3. Using a …

A New Semidesert Microtityus Kjellesvig-Waering, 1966 (Scorpiones: Buthidae) From Southeast Cuba, Greater Antilles., Rolando Teruel

Euscorpius

A new species of the buthid scorpion genus Microtityus Kjellesvig-Waering, 1966, is herein described from specimens of both sexes collected at three nearby localities in the western part of the Guantánamo Bay Area, southeast Cuba. It belongs in the "jaumei" species-group of the subgenus Microtityus (Parvabsonus) Armas, 1974 and is very peculiar not only by its external morphology (very distinct from its other Cuban congeners), but also by the unusual habitat where it occurs in and seems to be restricted to (dry and hot cactus scrub on volcanic sandy plain). The present contribution reinforces the position of this genus as …

Dual Geometry Schemes In Tetrel Bonds: Complexes Between Tf4(T = Si, Ge, Sn) And Pyridine Derivatives, Wiktor Zierkiewicz, Mariusz Michalczyk, Rafał Wysokiński, Steve Scheiner

Chemistry and Biochemistry Faculty Publications

When an N-base approaches the tetrel atom of TF4(T = Si, Ge, Sn) the latter moleculedeforms from a tetrahedral structure in the monomer to a trigonal bipyramid. The base can situateitself at either an axial or equatorial position, leading to two different equilibrium geometries.The interaction energies are considerably larger for the equatorial structures, up around 50 kcal/mol,which also have a shorter R(T··N) separation. On the other hand, the energy needed to deform thetetrahedral monomer into the equatorial structure is much higher than the equivalent deformationenergy in the axial dimer. When these two opposite trends are combined, it is the axial …

Ccne1 Amplification Is Associated With Poor Prognosis In Patients With Triple Negative Breast Cancer., Zi-Ming Zhao, Susan E Yost, Katherine E Hutchinson, Sierra Min Li, Yate-Ching Yuan, Javad Noorbakhsh, Zheng Liu, Charles Warden, Radia M Johnson, Xiwei Wu, Jeffrey H Chuang, Yuan Yuan

Faculty Research 2019

BACKGROUND: Triple negative breast cancer (TNBC) is aggressive with limited treatment options upon recurrence. Molecular discordance between primary and metastatic TNBC has been observed, but the degree of biological heterogeneity has not been fully explored. Furthermore, genomic evolution through treatment is poorly understood. In this study, we aim to characterize the genomic changes between paired primary and metastatic TNBCs through transcriptomic and genomic profiling, and to identify genomic alterations which may contribute to chemotherapy resistance.

METHODS: Genomic alterations and mRNA expression of 10 paired primary and metastatic TNBCs were determined through targeted sequencing, microarray analysis, and RNA sequencing. Commonly mutated …

Static And Dynamic Postural Control Deficits In Aging Fragile X Mental Retardation 1 (Fmr1) Gene Premutation Carriers., Zheng Wang, Pravin Khemani, Lauren M Schmitt, Su Lui, Matthew W Mosconi

Articles, Abstracts, and Reports

BACKGROUND: Individuals with premutation alleles of the fragile X mental retardation 1 (FMR1) gene are at risk of developing fragile X-associated tremor/ataxia syndrome (FXTAS) during aging. Characterization of motor issues associated with aging in FMR1 premutation carriers is needed to determine neurodegenerative processes and establish new biobehavioral indicators to help identify individuals at greatest risk of developing FXTAS.

METHODS: We examined postural stability in 18 premutation carriers ages 46-77 years and 14 age-matched healthy controls. Participants completed a test of static stance and two tests of dynamic postural sway on a force platform to quantify postural variability and complexity. CGG …

Microrna-4719 And Microrna-6756-5p Correlate With Castration-Resistant Prostate Cancer Progression Through Interleukin-24 Regulation, Dibash K. Das, Leah Persaud, Moira Sauane

Publications and Research

Prostate cancer (PCa) is the second leading cause of cancer death in the United States. The five-year survival rate for men diagnosed with localized PCa is nearly 100%, yet for those diagnosed with aggressive PCa, it is less than 30%. The pleiotropic cytokine Interleukin-24 (IL-24) has been shown to specifically kill PCa cells compared to normal cells when overexpressed in both in vitro and in vivo studies. Despite this, the mechanisms regulating IL-24 in PCa are not well understood. Since specific microRNAs (miRNAs) are dysregulated in PCa, we used miRNA target prediction algorithm tools to identify miR-4719 and miR-6556-5p as …

Vibration Analysis Of Healthy Skin: Toward A Noninvasive Skin Diagnosis Methodology, Rakshita Panchal, Luke Horton, Peyman Poozesh, Javad Baqersad, Mohammadreza Nasiriavanaki

Mechanical Engineering Publications

Several noninvasive imaging techniques have been developed to monitor the health of skin and enhance the diagnosis of skin diseases. Among them, skin elastography is a popular technique used to measure the elasticity of the skin. A change in the elasticity of the skin can influence its natural frequencies and mode shapes. We propose a technique to use the resonant frequencies and mode shapes of the skin to monitor its health. Our study demonstrates how the resonant frequencies and mode shapes of skin can be obtained using numerical and experimental analysis. In our study, natural frequencies and mode shapes are …

Potential New Biomarkers For Endometrial Cancer, Michelle H. Townsend, Zac E. Ence, Abigail M. Felsted, Alyssa C. Parker, Stephen R. Piccolo, Richard A. Robison, Kim L. O'Neill

Faculty Publications

Abstract

Background: Incidence of endometrial cancer are rising both in the United States and worldwide. As endometrial cancer becomes more prominent, the need to develop and characterize biomarkers for early stage diagnosis and the treatment of endometrial cancer has become an important priority. Several biomarkers currently used to diagnose endometrial cancer are directly related to obesity. Although epigenetic and mutational biomarkers have been identified and have resulted in treatment options for patients with specific aberrations, many tumors do not harbor those specific aberrations. A promising alternative is to determine biomarkers based on differential gene expression, which can be used to …

Optimization Of Photonic Nanojets Generated By Multilayer Microcylinders With A Genetic Algorithm, Yin Huang, Zhishen Zhen, Yuecheng Shen, Changjun Min, Georgios Veronis

Faculty Publications

We employ a genetic algorithm coupled with Mie theory to optimize the magnetic field intensity profile of photonic nanojets (PNJs) generated by multilayer microcylinders at visible wavelengths in free space. We first optimize five-layer microcylinders to elongate the PNJs. We show that a properly designed five-layer microcylinder structure can generate an ultra-long PNJ with a beam length ∼ 107.5 times the illumination wavelength λ0. We then optimize five-layer microcylinders to narrow the waist of PNJs. We show that a PNJ with a full-width at half maximum waist of ∼ 0.22λ0 can be obtained outside the surface of the optimized microcylinder. …

Genome-Wide Characterization, Molecular Evolution And Mexpression Profiling Of The Metacaspases In Potato (Solanum Tuberosum L.), Nehal Dubey, Maitri Trivedi, Suresh Varsani, Vishal Vyas, Manisha Farsodia, Sunil Kumar Singh

Department of Entomology: Faculty Publications

Metacaspases are distant relatives of animal caspases found in plants, protozoa and fungi. Some recent studies have demonstrated that metacaspases are involved in regulating the developmental and environmentally induced programmed cell death in plants. In this study, we identified metacaspase gene family in potato (Solanum tuberosum L.) and analyzed their expression pattern in various developmental tissues and stress responses of plants. There were eight metacaspase genes identified in the Peptidase (Cysteine protease) C14 family and based upon sequence alignment and phylogenetic analysis, a systematic nomenclature of potato metacaspases (SotubMCs) has been proposed. Three of the eight candidate genes showing homology …

Illumination Pattern Design With Deep Learning For Single-Shot Fourier Ptychographic Microscopy, Yi Fei Cheng , '21, Megan Strachan , '21, Zachary Weiss , '20, Moniher Deb , '19, Dawn M. Carone, Vidya Ganapati

Biology Faculty Works

Fourier ptychographic microscopy allows for the collection of images with a high space-bandwidth product at the cost of temporal resolution. In Fourier ptychographic microscopy, the light source of a conventional widefield microscope is replaced with a light-emitting diode (LED) matrix, and multiple images are collected with different LED illumination patterns. From these images, a higher-resolution image can be computationally reconstructed without sacrificing field-of-view. We use deep learning to achieve single-shot imaging without sacrificing the space-bandwidth product, reducing the acquisition time in Fourier ptychographic microscopy by a factor of 69. In our deep learning approach, a training dataset of high-resolution images …

Parlech: Parallel Long-Read Error Correction With Hadoop, Arghya Kusum Das, Kisung Lee, Seung Jong Park

Computer Science Faculty Research & Creative Works

Long-read sequencing is emerging as a promising sequencing technology because it can tackle the short length limitation of second-generation sequencing, which has dominated the sequencing market in past years. However, it has substantially higher error rates compared to short-read sequencing (e.g., 13% vs. 0.1%), and its sequencing cost per base is typically more expensive than that of short-read sequencing. To address these limitations, we present a distributed hybrid error correction framework, called ParLECH, that is scalable and cost-efficient for PacBio long reads. For correcting the errors in the long reads, ParLECH utilizes the Illumina short reads that have the low …

B Cell-Mediated Antigen Presentation Through Mhc Class Ii Is Dispensable For Atherosclerosis Progression, Jesse W Williams, Andrew Elvington, Skyler Kessler, Mary Wohltmann, Gregory F Wu, Gwendalyn J Randolph

2020-Current year OA Pubs

Depletion of B cells attenuates plaque development and modulates T cell responses in mouse models of atherosclerosis, suggesting that Ag presentation by B cells may promote disease progression. Thus, we set out to determine the role of B cell-mediated MHC class II (MHC II) Ag presentation during atherosclerotic plaque development. We developed murine conditional MHC II deletion and expression systems under control of the B cell-restricted CD19 promoter in an experimental model of atherosclerosis. Mice lacking MHC II expression only on B cells exhibited systemic shifts in germinal center and marginal zone B cell populations, leading to a reduced Ab …

Krill (Euphausia Superba) Distribution Contracts Southward During Rapid Regional Warming, Angus Atkinson, Simeon L. Hill, Evgeny A. Pakhomov, Volker Siegel, Christian S. Reiss, Valerie J. Loeb, Deborah K. Steinberg, Katrin Schmidt, Geraint A. Tarling, Laura Gerrish, Sévrine F. Sailley

School of Geography, Earth and Environmental Sciences

High-latitude ecosystems are among the fastest warming on the planet1. Polar species may be sensitive to warming and ice loss, but data are scarce and evidence is conflicting2,3,4. Here, we show that, within their main population centre in the southwest Atlantic sector, the distribution of Euphausia superba (hereafter, ‘krill’) has contracted southward over the past 90 years. Near their northern limit, numerical densities have declined sharply and the population has become more concentrated towards the Antarctic shelves. A concomitant increase in mean body length reflects reduced recruitment of juvenile krill. We found evidence for environmental controls on recruitment, including a …
