Professional Practices (ART 399)

When I was young I wasn't much into art. I liked doing my owns thing and looking at cool images and colors that grabbed my attention, now really understanding that I actually liked art. The way I really knew how to communicate my feelings was to draw them out since I struggled verbally expressing them. I really didn't know exactly what I was doing but I was drawing or doing other creative ways to express the way I was feeling at the moment to others. Sometimes to this day I still do that but I'm at lot better at expressing …

Professional Practices (ART 399)

Aside from the aesthetics of cartoons and video games that I was attracted to in childhood; other influences that often guide where works would go are personal experiences, our connection with nature and others, the development of the imagination, and the human eye. The pieces made from that influence contain something tied back to others, whether it is the use of various warm/cool hues, the use of nature and flowers, colorful clothing on figures, or hands and legs being slightly longer than the rest of a figure’s proportions. Artists like Yayoi Kusama, Bonnie Seeman, and Hayao Miyazaki have also impacted …

Professional Practices (ART 399)

A plethora of my artwork is based on imaginary animals and their role in reality or fantasy. I utilize pencil and charcoal to add depth and feeling to the piece whether it is colored or monochromatic. To make the drawings, I first gather some ideas from creatures from mythology or the virtual landscape and add some features of my own design. This passion for capturing creatures, real or fictional, can utilize their unusual adaptations from a scientific point of view as a way to merge two of my interests. I have always been fascinated by animals, especially mythical ones or …

Professional Practices (ART 399)

Since a young age, my art has been a proper channel in which it allows me to express my own lived experiences by visually processing the thoughts and emotions that are made through everyday living. The process in which art is made deepens the understanding of oneself. Why I bring into existence art is why I exist. One of the most important influences to the creation of my works is the fact that I am transgender. The way in which I exist in the world as well as the relationships created are also influenced by this aspect. As I continue …

My personal journey and the lived experience of women in society inspire my work. I speak to my own experiences and thoughts as a woman. I force people into a place of discomfort, causing them to think deeply about how society speaks to women and what is taught to us from birth, leaving them with thoughts that linger long after they have walked away. This gives them a window into my intrusive thoughts, traumas, and emotions. The Tulip Field speaks to the manner in which society deals with the sex industry and sex workers today as opposed to how they …

A Generalized Kodaira Vanishing Theorem For Lie Algebroids And A Riemann–Roch Theorem For Singular Foliation, Tengzhou Hu

Arts & Sciences Graduate Student Theses and Dissertations

A Lie algebroid is a generalization of Lie algebra that provides a general framework to describe the symmetries of a manifold. In this thesis, we first generalize the Kodaira vanishing theorem, which is a basic result in complex geometry, to K\"{a}hler Lie algebroids. The generalization of the Kodaira vanishing theorem states that the kernel of the Lie algebroid Laplace operator on Lie algebroid positive line bundle-valued $(p,q)$-forms vanishes when $p+q$ is sufficiently large. The most difficult part of the proof of the generalized Kodaira vanishing theorem is the generalization of the K\"{a}hler identities to Lie algebroids. Secondly, we introduce Lie …

From Mother To Infant, From Placenta To Gut: Understanding Varied Microbiome Profiles In Neonates, Riadh Cheddadi, Venkata Yeramilli, Colin Martin

2020-Current year OA Pubs

The field of human microbiome and gut microbial diversity research has witnessed a profound transformation, driven by advances in omics technologies. These advancements have unveiled essential connections between microbiome alterations and severe conditions, prompting the development of new frameworks through epidemiological studies. Traditionally, it was believed that each individual harbored unique microbial communities acquired early in life, evolving over the course of their lifetime, with little acknowledgment of any prenatal microbial development, but recent research challenges this belief. The neonatal microbiome's onset, influenced by factors like delivery mode and maternal health, remains a subject of intense debate, hinting at potential …

Dna Methylation-Mediated Rbpjk Suppression Protects Against Fracture Nonunion Caused By Systemic Inflammation, Ding Xiao, Liang Fang, Zhongting Liu, Yonghua He, Jun Ying, Haocheng Qin, Aiwu Lu, Meng Shi, Tiandao Li, Bo Zhang, Jianjun Guan, Cuicui Wang, Yousef Abu-Amer, Jie Shen

Challenging skeletal repairs are frequently seen in patients experiencing systemic inflammation. To tackle the complexity and heterogeneity of the skeletal repair process, we performed single-cell RNA sequencing and revealed that progenitor cells were one of the major lineages responsive to elevated inflammation and this response adversely affected progenitor differentiation by upregulation of Rbpjk in fracture nonunion. We then validated the interplay between inflammation (via constitutive activation of Ikk2, Ikk2ca) and Rbpjk specifically in progenitors by using genetic animal models. Focusing on epigenetic regulation, we identified Rbpjk as a direct target of Dnmt3b. Mechanistically, inflammation decreased Dnmt3b expression in progenitor cells, …
