Detection Theory For Accurate And Non-Invasive Skin Cancer Diagnosis Using Dynamic Thermal Imaging, Sebastian E. Godoy, Majeed M. Hayat, David A. Ramirez, Stephen A. Myers, R. Steven Padilla, Sanjay Krishna

Electrical and Computer Engineering Faculty Research and Publications

Skin cancer is the most common cancer in the United States with over 3.5M annual cases. Presently, visual inspection by a dermatologist has good sensitivity (> 90%) but poor specificity (< 10%), especially for melanoma, which leads to a high number of unnecessary biopsies. Here we use dynamic thermal imaging (DTI) to demonstrate a rapid, accurate and non-invasive imaging system for detection of skin cancer. In DTI, the lesion is cooled down and the thermal recovery is recorded using infrared imaging. The thermal recovery curves of the suspected lesions are then utilized in the context of continuous-time detection theory in order to define an optimal statistical decision rule such that the sensitivity of the algorithm is guaranteed to be at a maximum for every prescribed false-alarm probability. The proposed methodology was tested in a pilot study including 140 human subjects demonstrating a sensitivity in excess of 99% for a prescribed specificity in excess of 99% for detection of skin cancer. To the best of our knowledge, this is the highest reported accuracy for any non-invasive skin cancer diagnosis method.

Transcriptional Regulation Of Skeletal Muscle Atrophy-Induced Gene Expression By Muscle Ring Finger-1 And Myogenic Regulatory Factors, Karina Marie Kakareka

UNF Graduate Theses and Dissertations

Skeletal muscle wasting occurs as a corollary of numerous physiological conditions, including denervation, immobilization, and aging. The E3 ubiquitin ligases MuRF1 and MAFbx are induced under nearly all atrophy conditions and are believed to play a key role in protein degradation. Data in this thesis provides interesting new evidence that MuRF1 may also act as a transcriptional modulator of atrophy-induced genes or atrogenes. The transcriptional regulation of MuRF1 and MAFbx were characterized using a reporter gene system and exhibited repressed activity in C₂C₁₂ cells overexpressing MuRF1. Furthermore, ectopic expression of the myogenic regulatory factors (MRFs), MyoD and …

Survey Gear Comparisons And Shark Nursery Habitat Use In Southeast Georgia Estuaries, Jeffrey Cohen Carpenter

UNF Graduate Theses and Dissertations

Gill nets and longlines were compared as shark nursery sampling methodologies in inshore waters of Georgia to (1) assess differences in gear selectivity, bias, and stress of capture and (2) determine potential relationships between habitat features and shark distribution and abundance. Gear selectivity varied between gears as a function of both species and life stage resulting in significantly different estimates of species and life stage compositions. Juvenile bonnetheads (Sphyrna tiburo) and young of the year blacktip sharks (Carcharhinus limbatus) experienced significantly higher stress from gill net capture than longline. Major sources of bias are thought to …

Mercury Accumulation And Effects In The Brain Of Atlantic Sharpnose Sharks (Rhiszoprionodon Terranovae), Samantha L. Ehnert

UNF Graduate Theses and Dissertations

Sharks often bioaccumulate mercury (Hg) concentrations in their muscle to levels that threaten the health of human consumers. However, few published studies have examined if the high Hg levels seen in shark muscle also occur in the shark brain, or if Hg accumulation affects shark neurophysiology. Therefore, this study examined if shark brains accumulate significant levels of Hg, if Hg accumulation occurs in certain subcomponents of the brain, and if Hg accumulation is associated with oxidative stress effects on the shark central nervous system, with special focus on the Atlantic sharpnose shark (Rhizoprionodon terraenovae). Sharks were collected along …

Appreciating Neurodiversity: Asd Perceptions Of Experiences In A Higher Education Transition Program And The Implications For Higher Ed Leaders, Joanna L. Ale

UNF Graduate Theses and Dissertations

Over the past decade, the number of individuals being diagnosed with Autism Spectrum Disorder has risen substantially. One byproduct of increased diagnosis is that more and more students with Autism Spectrum Disorder are applying and being accepted to colleges and universities (Graetz & Spampinato, 2008; Jones, 2012; Smith, 2007; Taylor, 2005; Zager, Alpern, McKeon, Maxam, & Mulvey, 2013; Longtin, 2013; Adreon & Durocher, 2007; Zager & Alpern, 2010). Research in the field of Autism and Higher Education is in its infancy, with a dearth of the research focusing on the challenges and struggles that degree-seeking students with ASD face within …

Ptsd’S True Color; Examining The Effect Of A Short-Term Coloring Intervention On The Stress, Anxiety And Working Memory Of Veterans With Ptsd., Jourdan A. Rodak

UNF Graduate Theses and Dissertations

The aim of this study was to explore the effect a coloring condition had on minimizing anxiety and stress experienced daily by veterans. The effect that coloring had on working memory was also explored.

A sample of 24 armed forces veterans were split into two coloring conditions, a mandala and a free draw condition, and asked to complete the Primary Care PTSD Screen, the Perceived Stress Scale and the Brief State Trait Anxiety Inventory. Working memory scores were established via a Backward Digit Recall task; pre-and posttest scores were evaluated for significant differences.

Our research suggests the act of coloring, …

Can Coloring Reduce Stress And Increase Working Memory In The Elderly?, Alexus Lepere

UNF Graduate Theses and Dissertations

This study explores whether the observed effects of coloring on anxiety and stress apply to the elderly. Two coloring activities were administered to elderly participants to evaluate the effects on stress, anxiety, and working memory. The Mini Mental State Examination was used to establish cognitive level. The Perceived Stress Scale and Brief State Trait Anxiety Inventory were administered to obtain pretest and posttest scores on stress and anxiety levels. Working memory was measured using the Backward Digit Recall to test if the potential calming effects improve working memory. A near significant increase in stress scores was demonstrated in the mandala …

Britain's Green Fascists: Understanding The Relationship Between Fascism, Farming, And Ecological Concerns In Britain, 1919-1951, Alec J. Warren

UNF Graduate Theses and Dissertations

This study explores the relationship between fascism, fascist ideas, and environmental consciousness in Britain during the pre- and post-World War II decades. In examining this topic, two main questions arise. First, why did fascist intellectuals support environmentally conscious ideas, and how did they relate these positions to their political ideologies? Second, why were many environmentally conscious thinkers during this period attracted to fascism? This thesis will also address several related issues regarding fascism and environmental consciousness. These issues include what role environmental concerns played in the British Union of Fascist’s platforms and in fascism’s public appeal, and how that role …

An Equal Rights Amendment For The Twenty-First Century: Bringing Global Constitutionalism Home, Julie C. Suk

Articles

The last few years have seen a renewed push to constitutionalize sex equality in the United States. A generation after the federal Equal Rights Amendment (ERA) failed to be ratified by the requisite number of states, the ERA is on the platform of the 2017 Women's March on Washington. Oregon added a sex equality guarantee to its state constitution in 2014, joining 22 state constitutions and most constitutions around the world. Feminist coalitions, Hollywood celebrities, and members of Congress are vocally endorsing an ERA revival. Why is an ERA desired now, when judges have interpreted the Fourteenth Amendment to prohibit …

The Constitution Of Mothers: Gender Equality And Social Reproduction In The United States And The World, Julie C. Suk

Articles

The article explores the resurgence of the Equal Rights Amendment (ERA) in the United States, highlighting its potential to address ongoing gender inequalities and the role of social reproduction in modern society. It argues that the ERA, if ratified, could move beyond symbolic significance by integrating lessons from global constitutionalism, particularly the synthesis of gender equality and motherhood protections seen in European constitutions.

Simulations Of Coherent Synchrotron Radiation On Parallel Hybrid Gpu/Cpu Platform, B. Terzić, K. Arumugam, D. Duffin, A. Godunov, T. Islam, D. Ranjan, S. Sangam, Mohammad Zubair

Physics Faculty Publications

Coherent synchrotron radiation (CSR) is an effect of self-interaction of an electron bunch as it traverses a curved path. It can cause a significant emittance degradation, as well as fragmentation and microbunching. Numerical simulations of the 2D/3D CSR effects have been extremely challenging due to computational bottlenecks associated with calculating retarded potentials via integrating over the history of the bunch. We present a new high-performance 2D, particle-in-cell code which uses massively parallel multicore GPU/GPU platforms to alleviate computational bottlenecks. The code formulates the CSR problem from first principles by using the retarded scalar and vector potentials to compute the self-interaction …

Controlled Manipulation Of Floating Objects On Deformed Fluid Interfaces And Conditions For Stable Equilibria, Jose M. Carballo, Qi Ni, Jose Vasquez, Nathan B. Crane

Faculty Publications

At the millimeter scale, interactions between floating and semi-immersed objects are significant. The local curvature of the interface is modified by the weight/buoyancy forces of floating objects, and by the surface properties of semi-immersed objects. The curvature changes generate attractive (or repulsive) interactions between floating parts, and semi-immersed objects. This work demonstrates how electrowetting can manipulate these interactions in order to position, align, assemble and transport parts attached to the fluid interface. This demonstrates one way in which fluid interfaces can provide an alternative to standard pick and place technology for part positioning/assembly. Typically, the part/rod forces are purely attractive …

Pathways And Supply Of Dissolved Iron In The Amundsen Sea (Antarctica), P. St-Laurent, P. L. Yager, R. M. Sherrell, S. E. Stammerjohn, M. S. Dinniman

CCPO Publications

Numerous coastal polynyas fringe the Antarctic continent and strongly influence the productivity of Antarctic shelf systems. Of the 46 Antarctic coastal polynyas documented in a recent study, the Amundsen Sea Polynya (ASP) stands out as having the highest net primary production per unit area. Incubation experiments suggest that this productivity is partly controlled by the availability of dissolved iron (dFe).As a first step toward understanding the iron supply of the ASP, we introduce four plausible sources of dFe and simulate their steady spatial distribution using conservative numerical tracers. The modeled distributions replicate important features from observations including dFe maxima at …

Development Of An Age-Frequency Distribution For Ocean Quahogs Arctica Islandica On Georges Bank, Sara M. Pace, Eric N. Powell, Roger Mann, M. Chase Long, John M. Klinck

CCPO Publications

Ocean quahogs [Arctica islandica (Linnaeus, 1769)] are the longest-lived, noncolonial animal known today, with a maximum life span exceeding 500 y. Ocean quahogs are a commercially important bivalve, inhabiting the continental shelf of the North Atlantic Basin. Although considerable information exists on the growth and physiology of A. islandica, limited information is available regarding recruitment; accordingly, sustainably managing the fishery is a challenge. To investigate long-term recruitment trends, the age of ocean quahogs from Georges Bank which were fully recruited to the commercial fishery (>80 mm shell length) was determined by analysis of annual growth lines in …

Tick Haller's Organ, A New Paradigm For Arthropod Olfaction: How Ticks Differ From Insects, Ann L. Carr, Robert D. Michell Iii, Anirudh Dhammi, Brooke W. Bissinger, Daniel E. Sonenshine, R. Michael Roe

Biological Sciences Faculty Publications

Ticks are the vector of many human and animal diseases; and host detection is critical to this process. Ticks have a unique sensory structure located exclusively on the 1st pairs of legs; the fore-tarsal Haller's organ, not found in any other animals, presumed to function like the insect antennae in chemosensation but morphologically very different. The mechanism of tick chemoreception is unknown. Utilizing next-generation sequencing and comparative transcriptomics between the 1st and 4th legs (the latter without the Haller's organ), we characterized 1st leg specific and putative Haller's organ specific transcripts from adult American dog ticks, Dermacentor variabilis. The …
