Soft Modular Robots: From Modular Tensegrity Structures To Bioinspired Sea Robots, Luyang Zhao

Dartmouth College Ph.D Dissertations

The rapid advancement of robotics necessitates systems capable of adapting to complex, unstructured environments. Soft robots, with their flexibility and compliance, excel in delicate interactions, making them ideal for medical applications and search-and-rescue missions. Modular robots, on the other hand, offer reconfigurability, enabling diverse task-specific adaptations in dynamic settings. Despite their individual advantages, the integration of soft and modular robotics remains underexplored. This proposal aims to develop soft modular robots that combine the adaptability of soft robotics with the versatility of modularity. These systems will be capable of autonomously transitioning between locomotion, manipulation, and infrastructure assembly across land, water, and …

Single-Cell Analysis Of Clonal And Transcriptional Dynamics During Direct Reprogramming, Brent Biddy

Arts & Sciences Graduate Student Theses and Dissertations

Direct lineage reprogramming converts one cell type into another, a process characterized by significant heterogeneity. Single-cell genomic techniques have been instrumental in dissecting this variability, yet they often fail to preserve lineage relationships. Here, I present CellTagging, a sequential, combinatorial indexing method that enables the reconstruction of clonal history and gene expression dynamics at single-cell resolution. This facilitates the construction of multi-level lineage trees, providing insights into cellular reprogramming trajectories. We applied CellTagging to investigate direct lineage reprogramming of mouse embryonic fibroblasts into induced endoderm progenitors. Our analysis revealed two distinct reprogramming trajectories: one leading to successful conversion and another …

Effects Of Angptl3 Deficiency On The Regulation Of Hepatic Lipoprotein Production And Lipid Metabolism, Kendall Helene Burks

Arts & Sciences Graduate Student Theses and Dissertations

Cardiovascular disease is the leading cause of death worldwide. A major treatment goal is to lower plasma lipids, especially low-density lipoprotein cholesterol (LDL), the cardinal risk factor for coronary artery disease (CAD). Patients with familial hypercholesterolemia (FH) experience early-onset CAD due to extremely high LDL. Underdiagnosis and undertreatment of FH are exacerbated by limited therapeutic options. However, one strategy has successfully lowered LDL in FH patients: Inhibition of the hepatically secreted protein Angiopoietin-like protein 3 (ANGPTL3). Despite promising clinical data, the mechanism by which ANGPTL3 inhibition lowers LDL has not been fully described. Although ANGPTL3 has been shown to modulate …

Functional Diversification Of Rice Ago1 Proteins, Rachel Elie Jouni

Arts & Sciences Graduate Student Theses and Dissertations

Global demand for food is outpacing gains from conventional plant breeding. Scientists have turned to molecular crop breeding techniques to increase crop output and mitigate global hunger; however, a common setback in this process is the pleiotropic effects of target genes. We need to develop strategies to specifically modulate desired traits without incurring undesired penalties. Natural evolution frequently balances such tradeoffs through extensive regulation, which we can leverage to produce more specific results. Reproductive development is an important target of breeding efforts due to its direct effect on yield. Rice, a major staple food crop for half the world’s population, …

Targeting Nonsense-Mediated Rna Decay In Splicing Factor Mutant Myeloid Malignancies, Claudia Cabrera

Arts & Sciences Graduate Student Theses and Dissertations

Approximately 50% of patients with myelodysplastic syndromes (MDS) (which frequently progresses to secondary acute myeloid leukemia [AML]), 60% of chronic myelomonocytic leukemia (CMML) and 20% of de novo AML harbor heterozygous somatic mutations in spliceosome genes. We and others have shown that mutations in spliceosome genes U2AF1, SF3B1, SRSF2 and ZRSR2 cause alterations in RNA splicing, leading to production of numerous aberrant RNAs. Interestingly, spliceosome mutant cells are more sensitive to genetic alterations or drugs that further perturb RNA splicing, compared to wild-type cells. The sensitivity of spliceosome mutant cells to further perturbations in RNA splicing raises the possibility that …

Spatial Echoes, Joy Cherichel

Bachelor of Architecture Theses - 5th Year

This abstract critiques the limitations within the U.S. education system, arguing that its selective preservation of history often obscures crucial narratives, particularly regarding systemic racism. Focusing on the suppressed history of Oscarville and the expulsion of Black residents from Forsyth County, Georgia, in 1912, the proposal advocates for architectural intervention to combat this historical amnesia. The central research question explores how architecture can preserve and convey unbiased racial history to enhance education. The thesis posits that intentionally designed architecture can serve as a powerful and enduring educational tool, making it harder to ignore marginalized histories. To address this, the abstract …

In Light Of Design: The Architecture Of Ambiance, Dariusch Hakimi Gilani

Bachelor of Architecture Theses - 5th Year

Architectural education often emphasizes technical proficiency and efficiency over the development of sensory and emotional experience, despite the profound impact atmosphere has on the built environment. Architecture schools claim to prepare students for a broad range of creative careers, yet direct education in atmospheric design is frequently relegated to adjacent disciplines like interior design, production design, or themed entertainment design. This disconnect raises a critical question: Can architectural education teach technical engineering skill and atmospheric sensitivity simultaneously, without compromising either? Given the crucial role of atmosphere in shaping human experience within spaces, it is essential to integrate its study into …

Performative Biomechanics : Evolving Buildings Into Inhabitable Organisms, Josh Lopez

Bachelor of Architecture Theses - 5th Year

There has always been a connection between biology and architecture. Michael Pawlyn, in Biomimicry in Architecture, coined “biomechanical designs” to describe structural techniques derived from creatures. This study investigates chitin-based creatures. Crustaceans, insects, and microscopic organisms all have exoskeletons in nature. With a focus on crabs, other crustaceans and bugs, this study examines and evaluates the formal characteristics of chitin-based organisms. The architectural creations of OXMAN, NOX, which was founded by Lars Spuybroek; and Lebbeus Woods are among those that are analyzed and studied due to their inspiration from living things. They follow functional effectiveness in nature, which is why …

A Work[Play]Ce For All: Working Hard And Playing Hard Shouldn't Be This Hard, Mary E. Caldwell

Bachelor of Architecture Theses - 5th Year

62% of the United States Labor Force goes to an office every day. That means that nearly 6 out of every 10 Americans spend most of their days experiencing an ordinary office environment every week. Children, on the other hand, spend most of their days in school, where they are constantly given playful and enjoyable tasks to promote their learning. Why does this concept of promoting pleasant emotions in a person’s everyday life seem to disappear as we become older and our everyday life becomes more critical to well-being? Imagine if offices were designed to promote pleasant experiences.

Solar Sailing Adaptive Control Around The Earth-Moon Lagrange Point L4 For Stellar Observations, Luis Mendoza Zambrano

Doctoral Dissertations and Master's Theses

To expand our knowledge about the influence of the Sun in the cislunar region, as well as our understanding of shocks due to Coronal Mass Ejections and large coronal magnetic reconnection, a solar sailing approach is proposed to separately capture lunar occultations and observe the solar corona from L₄ of the Earth-Moon system. Single and multiple shooting techniques are described along with a pseudo arc-length continuation method for preliminary orbit design. Periodic orbits in the vicinity of L₄ are obtained in the context of the Earth-Moon circular restricted three-body problem (CR3BP) and the Sun-Earth-Moon bi-circular restricted four-body problem …

Chinese Students, Jim Crow Schools: Navigating Education In A Black-And-White Society, Amanda Young

Senior Honors Papers / Undergraduate Theses

Previous research on the history of education in the Jim Crow South has largely focused on the effects of legal segregation on Black communities. However, there existed another group: the Chinese. In the seemingly bifurcated system, their intermediate status was particularly discernible in the school. After Lum v. Rice (1927) stipulated that Chinese people, as members of the “colored” race, should be excluded from white schools, Chinese families sought other forms of education, including private tutors and church-sponsored mission schools. Still, they remained steadfast in their commitment to accessing white public education. The Chinese reproduced, acquiesced to, and in some …

Faculty, Staff and Student Publications

Age-related white matter (WM) microstructure maturation and decline occur throughout the human lifespan, complementing the process of gray matter development and degeneration. Here, we create normative lifespan reference curves for global and regional WM microstructure by harmonizing diffusion MRI (dMRI)-derived data from ten public datasets (N = 40,898 subjects; age: 3-95 years; 47.6% male). We tested three harmonization methods on regional diffusion tensor imaging (DTI) based fractional anisotropy (FA), a metric of WM microstructure, extracted using the ENIGMA-DTI pipeline. ComBat-GAM harmonization provided multi-study trajectories most consistent with known WM maturation peaks. Lifespan FA reference curves were validated with test-retest data …

Vanadyl Phthalocyanine As A Low-Temperature/Low-Pressure Catalyst For The Conversion Of Fructose To Methyl Levulinate, Juan Luna, Mataz Alcoutlabi, Elizabeth M. Fletes, Helia Magali Morales, Jason Parsons

School of Integrative Biological & Chemical Sciences Faculty Publications

In this study, a vanadyl phthalocyanine was synthesized and characterized using XRD, FTIR, and XPS, confirming the successful metalation of the phthalocyanine ring. XRD analysis showed the vanadyl phthalocyanine crystallized in the P-1 crystal lattice, with unit cell parameters a = 12.058 Å, b = 12.598 Å, and c = 8.719 Å, and the lattice angels were 96.203°, 94.941°, and 68.204°. FTIR spectroscopy supported the metalation by the disappearance of the N-H stretch of the non-metalated phthalocyanine. The vanadyl phthalocyanine was tested as a heterogenous catalyst for the conversion of fructose into methyl levulinate in H2SO4–methanol and HCl–methanol systems. The …

Faculty, Staff and Students Publications

Patients diagnosed with metastatic triple negative breast cancer (mTNBC) have limited treatment options, are more prone to develop resistance and are associated with high mortality. A cold tumor immune microenvironment (TIME) characterized by low T cells and high tumor associated macrophages (TAMs) in mTNBC is associated with the failure of standard-of-care chemotherapy and immune checkpoint blockade (ICB) treatment. We demonstrate that the combination of immunomodulatory metronomic Cyclophosphamide (CTX) coupled with anti-CSF-1R antibody targeted therapy (SNDX-ms6352) and anti-PD-1 (ICB), was highly effective against aggressive metastatic syngeneic

Experiences Of Support And Success For Students Of Color In The Midwifery Educational Setting, Laura Jenson

Dissertations and Theses

The United States spends more on healthcare than any other developed country, yet perinatal health outcomes are among the worst, particularly for Black and Indigenous pregnant women and people. Structural and societal racism has contributed greatly to these inequities, and while a diverse perinatal healthcare workforce has the potential to mitigate the impact of pervasive racism, professions such as nurse-midwifery have evolved over time to be predominately white. The purpose of this study is to explore how students of color experience support and apply personal strategies for success in the midwifery educational setting. A basic qualitative study was done using …

A Self‐Monitoring Mobile App To Mitigate Risk Factors For Suicide And Self‐Harm In Junior (Resident) Doctors: A Review, Thematic Analysis And Concept Proposal, Rohit Shankar

Peninsula Medical School

Doctors, particularly those in training in the UK, are exposed to high levels of stress in their work, which can lead to burnout and mental health problems. According to the health and safety executive (HSE) Management UK standards, employers should recognise and minimise work-related stress for staff. Our review looks to examine if known risk factors for suicide and self-harm in doctors align with the themes of the HSE management standards on stress control i.e., demand, control, support, relationships, role, and change and if so, could this be used to build a self-awareness digital application. Four research databases were searched …

Marine Viruses: Biogeochemical Implications And Potential Applications, Faiza A Fattouh, Sahar W.M. Hassan

Blue Economy

Viruses are the most plentiful microorganisms in the ecosystem and exhibit excessive diversity in relations to infection cycle, host specificity and size. Since the discovery of great viral distribution in marine ecosystems, the ecological significance of viruses to marine environment has become gradually evident. Lytic viruses trigger lysis of the host cell to give the new progeny and thus readdress nutrients from higher to lower trophic levels. Consequently, marine viruses exhibit direct or indirect influence on the capacity of carbon sequestration, exchange of gases in the ocean and biogeochemical cycles in addition to affecting microbial population dynamics. Marine viruses are …

The transmission and reflection characteristics are discussed.

Surface Impact Dissociation Of Neutralized Ions: Studying Unimolecular Gas-Phase Reactions In The Context Of Cassini Inms Data, Dallin Tyger, Brandon Judd, Elijah Pehrson, Noah Durst, Daniel E. Austin

Utah Space Grant Consortium

Analysis of spaceborne analytes using mass spectrometers is complicated by hypervelocity impacts (v > 6 km s^-1), which induce dissociative scattering of analyte molecules and obscure compositional signatures. However, neutral dissociative scattering remains poorly understood due to the lack of controlled experimental data. To address this gap, we are developing the Surface Impact Neutralization Dissociation Instrument (SINDI), a laboratory platform that reproduced and analyzes these processes under controlled conditions. SINDI implements a two-stage experiment. First, mass-selected ions are accelerated onto a gold-plated surface to induce neutralization and dissociation. Second, following dissociation, the resulting neutral fragments are adsorbed onto …

This paper presents a complete system integration strategy for a proven Charge Detection Mass Spectrometry (CDMS) instrument designed to analyze charged dust particles on Mars. To enable deployment in a power-constrained rover environment, an ultra-low supply voltage (ULV) analog-to-digital converter (ADC) is required. ADC architectures operating below 0.21 V are compared to identify candidates that meet the system's stringent power and performance demands. A voltage-controlled oscillator (VCO)-based ADC is proposed and for ULV operation. Circuit-level implementations of VCO topologies are designed and evaluated in the TSMC 28 nm CMOS process using Cadence simulations. Based on simulation results, a VCO-CDAC topology …

A Pressure-Based Estimate Of Multi-Orifice Synthetic Jet Performance, Rhett T. Parry, Tim Berk

Utah Space Grant Consortium

Multiphase turbulence is a ubiquitous mechanism that drives the motion of fluid and particulate. In order to understand the behavior of this complex mechanism, it is critical to build facilities where driving parameters can be studies. Various flow actuators are used to drive turbulence, but we use synthetic jets for their geometric customizability and wide range operating parameters. Many studies based on synthetic jets focus on characterizing velocity while omitting the connection to turbulence. Additionally, most work in the existing literature is tied to the non-dimensional numbers but can obscure the limitations regarding both size and allowable driving conditions of …

A Methodology To Quantify The Shielding Efficiency Of Novel Radiation Shielding Materials, Jenny R. Whiteley, Tyler Heggenes, J.R. Dennison
