This dissertation is an ethnographic inquiry of artificial intelligence (AI) in the techno-landscape of three major metropolitan areas in the United States. It traces the ways in which both experts and non-experts talk about their interactions with AI via machines, robots, and other devices, and how the ways in which people deal with AI-technologies have come to shape how we think about our own ways of going about doing things. The goal is to discern what the social ramifications of this technology may be as relationships and relations are formed betwixt and between people and artificially intelligent things.

Magnetotransport Properties Of Polycrystalline Mn_(3-X)Fe_Xsn (X = 1, 2) Thin Films, Duston Wetzel

Dissertations

The incredible progress of the microelectronics industry in the last several decades hasbeen primarily due to the progressive miniaturization and optimization of the MOSFET. However, the rate of this progress is becoming unsustainable by these means. Of several proposed replacements, one of the most popular ideas is to utilize electronic spin in logical processing. The discovery of Giant Magntoresistance (GMR) in layered thin film heterostructures and the subsequent development of Tunneling Magnetoresistance (TMR) devices revolutionized magnetic field sensing, which allowed magnetic domains in hard drives to get much smaller. This enabled hard drives to get denser, but because current charge-based …

Modulation Of Piezo Mechanosensors: Exploring The Effects Of Proteinogenic Sulfur-Containing Amino Acids And Propofol, Donggyeom Yu

Dissertations

Organisms are constantly subjected to mechanical stimuli originating from their environment or internal activities. To sense and properly handle such mechanical cues, the conversion of mechanical signals into electrochemical signals occurs continuously within the organisms. Mechanosensitive ion channels (MSCs) are pivotal participants in this process, being ready to open to allow the movement of ions across cellular membranes in response to mechanical stimulation. Piezo1 and Piezo2 mechanosensitive cation channels are evolutionarily conserved MSCs, taking part in various physiological processes, including bone formation and touch sensation. Mutations in Piezo1 or Piezo2 lead to pathological conditions and overexpression of the channels is …

Previous work focused on a millimeter-sized CO₂-BRPPG in open fractures, but its performance in high-permeability channels with pore throat networks remained unexplored. This study used a sand pack model to evaluate a micro-sized CO₂-BRPPG under varying conditions of salinity, gel concentration, and pH. at ambient conditions, the equilibrium swelling ratio (ESR) of the gel reached 76 times its original size. This ratio decreased with increasing salinity but remained stable …

The Role Of Lifr Signaling In Innate Immunity, Laura Kahn Serrudo

Dissertations and Theses (Open Access)

The localized signals that bone marrow (BM) hematopoietic stem cells (HSCs) and immune cells receive are critical in regulating their responses in the steady state and inflammation. Monocytes are an abundant and key population in the innate immune response that originates in the BM, and they circulate to monitor the periphery. Monocytes are composed of many subsets that have essential and specific functions, including swift egress from the BM, production of pro-inflammatory cytokines, and differentiation into monocyte-derived dendritic cells (MoDCs), which are required for efficient pathogen eradication.

Here, we uncovered LIFR (leukemia inhibitory factor receptor) restrains low-grade chronic inflammation in …

Oncolytic Viruses Enhance Long-Term Nk Cell Anti-Tumor Cytotoxicity Through Ap-1 And Irf Pathway Activation, Xin Ru Jiang

Dissertations and Theses (Open Access)

Natural killer (NK) cell therapeutics have emerged as a promising strategy in adoptive cellular therapy. While genetic modifications of NK cells can enhance their antitumor activity, modulating the tumor to augment NK cell recognition and function remains underexplored. In this study, we investigated the combination of NK cells with oncolytic viruses to treat solid tumors, specifically pancreatic ductal adenocarcinoma and glioblastoma. We demonstrated that infecting tumor cells with the oncolytic adenovirus Delta-24-RGD significantly increases their susceptibility to NK cell cytotoxicity, driven by a hyperactivated NK cell phenotype characterized by elevated expression of activating receptors and cytotoxicity markers. In a patient-derived …

Smooth Muscle Cell Stress Response: Essential In Atherosclerotic Pathogenesis, Pujun Guan

Dissertations and Theses (Open Access)

Atherosclerosis remains the leading cause of death worldwide. Recent research using lineage tracing and single-cell RNA sequencing unveiled a previously undescribed and prominent role of smooth muscle cells (SMCs) in atherosclerotic plaque formation. SMCs undergo complex phenotypic modulation characterized by de-differentiation of SMCs and heterogeneously increased expression of markers for macrophages, fibroblasts, chondrocytes, and mesenchymal stem cells as plaques form. Cultured SMCs exposed to exogenous cholesterol mimic many of the phenotypic changes associated with plaque formation, and our lab determined this SMC modulation is driven by cholesterol entering the endoplasmic reticulum (ER) and triggering ER stress and PERK signaling. Further, …

Assessing The Temporal Role Of Mir-200 Loss In Murine Models Of Nsclc, Jared Fradette

Dissertations and Theses (Open Access)

Lung cancer is the leading cause of cancer related deaths in the United States, with non-small cell lung cancer (NSCLC) making up a majority of new diagnoses. Metastasis is the big killer in NSCLC and is driven by epithelial-mesenchymal transition (EMT) and immune evasion. The microRNA 200 family is a master regulator of EMT and is implicated in immune regulation. In this study we have developed a novel genetically engineered mouse model (GEMM) and derived primary cell lines from them to explore the role of microRNA-200 in early EMT and immune changes. Our model combines conditional activation of Kras^{G12D …}

Practical And Lightweight Defense Against Website Fingerprinting, Colman Mcguan, Chansu Yu, Kyoungwon Suh

Electrical and Computer Engineering Faculty Publications

Website fingerprinting is a passive network traffic analysis technique that enables an adversary to identify the website visited by a user despite encryption and the use of privacy services such as Tor. Several website fingerprinting defenses built on top of Tor have been proposed to guarantee a user's privacy by concealing trace features that are important to classification. However, some of the best defenses incur a high bandwidth and/or latency overhead. To combat this, new defenses have sought to be both lightweight - i.e., introduce a small amount of bandwidth overhead - and zero-delay to real network traffic. This work …
