The essay recounts the author’s experiences conducting ethnographic studies in the winter months in Finland and discusses the various challenges that environmental conditions produce for researchers.
Rearrangement Operations On Unrooted Phylogenetic Networks, Remie Janssen, Jonathan Klawitter
Rearrangement Operations On Unrooted Phylogenetic Networks, Remie Janssen, Jonathan Klawitter
Theory & Applications of Graphs
Rearrangement operations transform a phylogenetic tree into another one and hence induce a metric on the space of phylogenetic trees. Popular operations for unrooted phylogenetic trees are NNI (nearest neighbour interchange), SPR (subtree prune and regraft), and TBR (tree bisection and reconnection). Recently, these operations have been extended to unrooted phylogenetic networks, which are generalisations of phylogenetic trees that can model reticulated evolutionary relationships. Here, we study global and local properties of spaces of phylogenetic networks under these three operations. In particular, we prove connectedness and asymptotic bounds on the diameters of spaces of different classes of phylogenetic networks, including …

‘Am I Turning Into A Man?’ Experiences Of Pakistani Women With Pcos, Rida E Zehra Zaidi
MSJ Capstone Projects
According to the National Institutes of Health, 20 – 25% of all regularly ovulating women have PCOS. This disorder has a range of visible symptoms including excessive weight gain, hirsutism, acne, and hair loss among others. These symptoms make it difficult for women with the syndrome to fit the femininity ideals of the society, as it demands female bodies to be slim, smart, hair less, and to have porcelain skin and regular menstrual cycles. Women with PCOS and other health problems in Pakistan spend all their lives fighting unnecessary battles. This struggle has severe impacts on their physical and mental …

Beavers Alter Stream Macroinvertebrate Communities In Northeastern Utah, Susan E. Washko, Brett B. Roper, Trisha Brooke Atwood
Beavers Alter Stream Macroinvertebrate Communities In Northeastern Utah, Susan E. Washko, Brett B. Roper, Trisha Brooke Atwood
Watershed Sciences Faculty Publications
- Understanding changes in macroinvertebrate communities is important because they play a large role in stream ecosystem functioning, and they are an important food resource for fish. Beaver‐induced changes to stream morphology could alter macroinvertebrate communities, which in turn could affect food webs and ecosystem function. However, studies investigating the effects of North American beaver activities on macroinvertebrates are rare in the inter‐mountain west, an area with high potential for beaver‐assisted restoration.
- The aim of this study was to quantify differences in the macroinvertebrate community between unaltered segments of streams and within beaver ponds in north‐eastern Utah, U.S.A. We assessed macroinvertebrate …

DNA damage responses (DDR) to double-strand breaks (DSBs) alter cellular transcription programs at the genome-wide level. Through processes that are less well understood, DSBs also alter transcriptional responses locally, which may be important for efficient DSB repair. Here, we developed an approach to elucidate the
Dynamics And Control In Spiking Neural Networks, Fuqiang Huang
Dynamics And Control In Spiking Neural Networks, Fuqiang Huang
McKelvey School of Engineering Graduate Student Theses & Dissertations
In the brain, neurons (brain cells) produce electrical impulses, or spikes, that are thought to be the substrate of information processing and computation. Through enigmatic processes, these spikes are ultimately decoded into perceptions and actions. The nature of this encoding and decoding is one of the most pervasive questions in theoretical neuroscience. In other words, what are the specific functions enacted by neural circuits, through their biophysics and dynamics? This thesis examines the dynamics of neural networks from the perspective of control theory and engineering. The pivotal concept is that of the normative synthesis of neural circuits, wherein neural dynamics …
Longitudinal Acoustic Traps: Design, Fabrication, And Evaluation For Biological Applications, Michael Moore Binkley
Longitudinal Acoustic Traps: Design, Fabrication, And Evaluation For Biological Applications, Michael Moore Binkley
McKelvey School of Engineering Graduate Student Theses & Dissertations
Acoustofluidics combine ultrasonic actuation with small-volume microfluidic channels to enable precise, contactless object manipulation for a range of applications from serial chemical processing to blood component separation and single-cell analysis. Micron- to millimeter-scale vibrational waves generate reproducible pressure fields within the microfluidic channels and chambers. By exploiting the material property mismatch between a particle (polymeric and silica beads, cells, etc.) and a suspending fluid, the acoustic radiation force is used to move particles toward regions of low (nodes) or high pressure (antinodes). An understanding of these field-particle interactions is applied to design and implement complicated channel architectures for preferential segregation …

Rhodococcus Opacus Pd630 Genetic Tool Development To Enable The Conversion Of Biomass, Drew Michael Delorenzo
McKelvey School of Engineering Graduate Student Theses & Dissertations
The discovery of fossil fuels facilitated a new era in human history and allowed many firsts, such as the mass production of goods, the ability to travel and communicate long distances, the formation of population dense cities, and unprecedented improvements in quality of life. Alternative sources of energy and chemicals are needed, however, as hydrocarbon reserves continue to deplete and the effects of burning fossils on the planet become better understood. Lignocellulosic biomass is the most abundant raw material in the world and a viable alternative to petroleum-derived products. The pre-treatment of lignocellulose (e.g., thermocatalytic depolymerization, enzymatic hydrolysis, pyrolysis, etc.) …
Three-Dimensional Image Reconstruction In Transcranial Photoacoustic Computed Tomography, Joemini Poudel
Three-Dimensional Image Reconstruction In Transcranial Photoacoustic Computed Tomography, Joemini Poudel
McKelvey School of Engineering Graduate Student Theses & Dissertations
Photoacoustic computed tomography (PACT) is an emerging imaging modality that exploitsoptical contrast and ultrasonic detection principles to form images of the photoacousticallyinduced initial pressure distribution within tissue. The PACT reconstruction problemcorresponds to an inverse source problem in which the initial pressure distribution is recoveredfrom measurements of the radiated pressure wavefield. A major challenge in transcranialPACT brain imaging is compensation for aberrations in the measured data due to the presenceof the skull. Ultrasonic waves undergo absorption, scattering and longitudinal-to-shear wavemode conversion as they propagate through the skull. To properly account for these effects, awave-equation-based inversion method should be employed that can …
Structural And Tissue-Level Adaptations Of Lumbar Intervertebral Discs In Humans With Inducible Low Back Pain Symptoms, Christian Isaiah Weber
Structural And Tissue-Level Adaptations Of Lumbar Intervertebral Discs In Humans With Inducible Low Back Pain Symptoms, Christian Isaiah Weber
McKelvey School of Engineering Graduate Student Theses & Dissertations
Low back pain (LBP) is a devastating musculoskeletal ailment that impacts majority of the global population. Up to 95% of cases are considered nonspecific where the origin is unclear. Although there is a diagnosis with these cases, there lacks specificity that would help individuals with treatment and pain management. Imaging techniques such as magnetic resonance imaging (MRI) are primarily utilized in the diagnosis of LBP as it illuminates internal structures of the spine. One important structure clearly identified with MRI is the intervertebral disc (IVD) that is susceptible to injury and disease. Further, diagnostic imaging is performed lying down where …

Aggression In August Wilson’S King Hedley Ii, Asma’A Mohannad Saad, Muthanna Mohammad Sultan
Alustath Journal for Human and Social Sciences
The need for investigating the stereotypical image of the African American males as aggressive, criminal individuals brings this research to address this sensitive issue. But the stereotypes of the African American have drawn the attention of many black writers and psychiatrists who tried to dismantle these images by revealing the social, psychological, and socioeconomic factors which contribute in this phenomenon. This paper highlights the reasons that drive the black males to adopt aggression through analyzing August Wilson’s King Hedley II (1999). In this play, Wilson portrays the widely spread aggression and its negative consequences. He also goes a step further …
Ecocritical Consciousness In Shakespeare’S The Winter’S Tale, Birzo Abdulkadir Mohammad, Azad Hamad Sharif
Ecocritical Consciousness In Shakespeare’S The Winter’S Tale, Birzo Abdulkadir Mohammad, Azad Hamad Sharif
Alustath Journal for Human and Social Sciences
The present study focuses on the eco critical elements in The Winter’s Tale (1610-1611) by William Shakespeare (1564 –1616), which is an outstanding example of the literary writing communicating ecological consciousness. Having examined William Shakespeare’s contribution to understanding nature it can be stated that nature is one of the key concepts of the author. He was highly aware of the nature and humans connection, importance of nature as both utilitarian and spiritual object. That is why Shakespeare’s concept of nature is colored with mainly positive tones. The most typical words for natural world are “fine” and “beauty”. In contrast to …

Gender Differences In Early Communication, Language Acquisition And Development: A Descriptive Study, رشا عبد الرضا سعيد, رشا عبد المنعم عزيز
Alustath Journal for Human and Social Sciences
Parents pay a significant attention to the first words children utter. However, first words are not the actual beginning of communication. Much earlier, babies begin to communicate their feeling via making eye contact, pointing, crying, squealing, and other gestures. Furthermore, they perceive language earlier than making others understand them. The aim of this paper is to tackle the variations between the two sexes starting from the stages of language acquisition in normal children, the differences between the two genders in language vocalization within each stage. Next, the distinctions in acquiring a particular communicative competence and the causes behind this difference …

Development Of High-Speed Photoacoustic Imaging Technology And Its Applications In Biomedical Research, Yun He
McKelvey School of Engineering Graduate Student Theses & Dissertations
Photoacoustic (PA) tomography (PAT) is a novel imaging modality that combines the fine lateral resolution from optical imaging and the deep penetration from ultrasonic imaging, and provides rich optical-absorption–based images. PAT has been widely used in extracting structural and functional information from both ex vivo tissue samples to in vivo animals and humans with different length scales by imaging various endogenous and exogenous contrasts at the ultraviolet to infrared spectrum. For example, hemoglobin in red blood cells is of particular interest in PAT since it is one of the dominant absorbers in tissue at the visible wavelength.The main focus of …

Cytogps: A Web-Enabled Karyotype Analysis Tool For Cytogenetics, Zachary B Abrams, Lin Zhang, Lynne V Abruzzo, Nyla A Heerema, Suli Li, Tom Dillon, Ricky Rodriguez, Kevin R Coombes, Philip R O Payne
Open Access Publications
SUMMARY: Karyotype data are the most common form of genetic data that is regularly used clinically. They are collected as part of the standard of care in many diseases, particularly in pediatric and cancer medicine contexts. Karyotypes are represented in a unique text-based format, with a syntax defined by the International System for human Cytogenetic Nomenclature (ISCN). While human-readable, ISCN is not intrinsically machine-readable. This limitation has prevented the full use of complex karyotype data in discovery science use cases. To enhance the utility and value of karyotype data, we developed a tool named CytoGPS. CytoGPS first parses ISCN karyotypes …
Christianity + Schooling On Nature Versus Culture In Amazonia, Aparecida M. N. Vilaça
Christianity + Schooling On Nature Versus Culture In Amazonia, Aparecida M. N. Vilaça
Tipití: Journal of the Society for the Anthropology of Lowland South America
Based on the analysis of Evangelical Biblical translations, as well as on the school writing of Wari' (Southwestern Amazonia) students, produced in indigenous secondary school classrooms and at the intercultural university, this article aims to show how, in both church and school, a nature separate from humans is invented with which they should relate in a utilitarian and also contemplative way. Simultaneously nature’s opposite is invented–a culture that excludes animals and subjects them.
Tubes And Androgyny: Comment On "Thinking Through Tubes", Françoise Barbira Freedman
Tubes And Androgyny: Comment On "Thinking Through Tubes", Françoise Barbira Freedman
Tipití: Journal of the Society for the Anthropology of Lowland South America
In this comment on Stephen Hugh-Jones’s "Thinking Through Tubes" Françoise Barbira Freedman offers a feminist meditation on the semiotics of androgyny in Northwest Amazonian shamanism, ritual life and mythology. By focusing on processes of detotalization and retotalization that move beings from an androgynous state to a single-sex identity and back again, Barbira Freedman reveals a dynamic "one sex, two genders model of androgyny" that could not be further from a concept of androgyny as blurred gender. These movements in and out of a one sex state are largely the preserve of men so that androgynous features of the cosmos are …

Cosmology And Practice In Amazonia: The Inspiring Career Of Stephen Hugh-Jones, Chloe Nahum-Claudel, Olivier Allard
Tipití: Journal of the Society for the Anthropology of Lowland South America
Stephen Hugh-Jones’s ethnographic and collaborative engagement with the peoples of the Pirá-Paraná and, more widely, the Vaupés and Upper Rio Negro today spans 50 years. In this Introduction we chart the evolution of Hugh-Jones’s hybrid identity as iconoclast scholar, knowledgeable elder, and long-term collaborator. A biographical sketch identifies phases in this anthropological life: that of the ethnographer and initiate, steeped in the intellectual world of Barasana shaman-priests; that of lecturer and theorist in anthropology; and that of areal specialist, developing a synthesis of the ethnography of North West Amazonia through an engagement with Brazilian and indigenous intellectuals. We characterize the …
First-Personal Body Aesthetics As Affirmations Of Subjectivity, Madeline Martin-Seaver
First-Personal Body Aesthetics As Affirmations Of Subjectivity, Madeline Martin-Seaver
Contemporary Aesthetics (Journal Archive)
This paper redirects some of the philosophical discussion of sexual objectification. Rather than contributing further to debates over what constitutes objectification and whether it is harmful, I argue that aesthetic experience is a useful tool for resisting objectification. Attending to our embodied experiences provides immediate evidence that we are subjects; aesthetically attending to that evidence is a way of valuing it. I consider the human body as an aesthetic site, then as an ethico-aesthetic site, and finally as a site of resistance. In addition to deepening accounts of body aesthetic experience, this paper helps frame human bodies as integral to …
Habitat Selection Of The Spotfin Killifish In Coastal Connecticut, Megan L. Upp
Habitat Selection Of The Spotfin Killifish In Coastal Connecticut, Megan L. Upp
Master's Theses
The Spotfin Killifish (Fundulus luciae) is a salt marsh inhabitant, occupying a habitat subject to change from 1) historic changes from mosquito ditching practices to 2) more contemporary anthropogenic changes from sea level rise and coastal development. Though thought to be a habitat specialist along the Atlantic coast, Spotfin Killifish resource selection has yet to be quantified. Spotfin Killifish presence or absence data was recorded with measured habitat characteristics at sites along a 14 km stretch of coastal Connecticut. Three hypotheses were proposed to create probabilistic models that could predict Spotfin Killifish presence or absence using logistic regression: …
Allies In Training: The Construction & Management Of Cis Allyship At State University, Davida J. Schiffer
Allies In Training: The Construction & Management Of Cis Allyship At State University, Davida J. Schiffer
Master's Theses
Many universities provide LGBT Ally Training Programs, but who are the allies who attend them? My research examines how participants conceptualize cis allyship and how they enact it in their professional and personal lives. In describing the gendered and racialized role of cis allyship, I situate my analysis in theories of doing gender & performativity (West & Zimmerman 1987; Johnson 2013) and the scholarship around white allies in academic diversity narratives (Bonilla-Silva 2006; Collins & Bilge 2016). Focusing on an Ally Training program at State University, I conducted an ethnography of 4 Ally Trainings and performed 21 interviews with 12 …
Atrial Fibrillation Detection From Smartwatch Based Photoplethysmography Signals, Syed Khairul Bashar
Atrial Fibrillation Detection From Smartwatch Based Photoplethysmography Signals, Syed Khairul Bashar
Master's Theses
Detection of atrial fibrillation (AF) from a wrist watch photoplethysmography (PPG) signal is important because the wrist watch form factor enables long term continuous monitoring of arrhythmia in an easy and non-invasive manner. We have developed a novel method not only to detect AF from a smart wrist watch PPG signal, but also to determine whether the recorded PPG signal is corrupted by motion artifacts or not. In order to detect the motion and noise artifacts from PPG signal, we have used both the accelerometer signal and variable frequency complex demodulation based time-frequency analysis of the PPG signal. After the …

McKelvey School of Engineering Graduate Student Theses & Dissertations
Twenty million Americans suffer from peripheral nerve injury (PNI) caused by trauma and medical disorders, with approximately $150 billion spent in annual health-care dollars in the United States. Even with proper surgical reconstruction, less than 50% of the patients achieve satisfactory functional recovery. The gold standard surgical repair for long gaps (>3cm) is the autologous nerve graft, despite its disadvantages such as donor site morbidity, risk of infection, and increased cost. Alternative methods, such as acellular nerve grafts (ANA), are ineffective for large lesion gaps because of the lack of cells and regeneration factors. Recent efforts have been focused …
