Community Detection Using Deep Learning: Combining Variational Graph Autoencoders With Leiden And K-Truss Techniques, Jyotika Hariom Patil, Petros Potikas, William B. Andreopoulos, Katerina Potika

Faculty Research, Scholarly, and Creative Activity

Deep learning struggles with unsupervised tasks like community detection in networks. This work proposes the Enhanced Community Detection with Structural Information VGAE (VGAE-ECF) method, a method that enhances variational graph autoencoders (VGAEs) for community detection in large networks. It incorporates community structure information and edge weights alongside traditional network data. This combined input leads to improved latent representations for community identification via K-means clustering. We perform experiments and show that our method works better than previous approaches of community-aware VGAEs.

Global Metaphors For Wisdom: Philosophy As A Species Of The Genus Hao-Xue, Joshua Mason

Comparative Philosophy

Many philosophers have refused to recognize Chinese traditions as genuinely philosophical. The conceptual foundations of these exclusionary efforts appear in Aristotle’s dividing philosophy from rhetoric, then associating philosophy with truth, and rhetoric with metaphor. The Chinese have frequently been defined as metaphorical thinkers, in contrast with the logical, scientific, or literal pursuits of Occidental traditions. Because metaphor is classed with rhetoric, and Chinese was associated with metaphor, critics had a way to say that the Chinese weren’t participating in philia-sophia as rational inquiry into truth. I draw on two strands of 20^th century philosophy to move us beyond this …

From Contemplation To Counseling: Exploring Philosophical Practice By Constructive-Engagement Strategy Of Comparative Philosophy, Xiaojun Ding, Chao Yang, Peter Harteloh, Feng Yu

It offers a philosophical alternative to psychological counseling, focusing on reasoning to address life’s challenges and ethical dilemmas. The paper examines the integration …

Chinese Feminist Philosophy: Philosophizing Chinese Feminism In Transcultural Contexts, Yuanfang Dai

Comparative Philosophy

This paper aims to develop a Chinese feminist philosophy while positioning a transcultural approach as an alternative to transnational and national feminism. It focuses on Chinese feminist scholarship from the mid-1990s to the present. My main argument is that the intellectual development of Chinese feminist scholarship in the past three decades has been significantly influenced by U.S.-centric global feminism and international feminism, while at the same time being drawn from an existing history of feminism in China and reflections on the complicated relationship between global influences and local Chinese conditions. Transcultural feminism is something I see emerging out of the …

A Realist Daoism: Reading The Zhuang-Zi With Lao Zi's Daoist Realism, Wai Lok Cheung

Comparative Philosophy

A realist Daoism is best illustrated through contrasting with something less robust. Chad Hansen’s Daoism may be understood as a linguistic constructivism and is thus a good candidate. I challenge his interpretation of the Zhuang-Zi and respond with a realist understanding of daos. The resultant realist Daoism is to be understood given a Daoist realism from Lao Zi’s Dao-De-Jing, whose realist flavour is constituted by some dao sometimes, if not always, outrunning us. The present paper thus situates Zhuang Zi better as inheriting Daoism from Lao Zi, contributing to classical Daoism with a relativity …

Righteousness Versus Yi: Two Senses Of Justice, Cuiting Chen

Comparative Philosophy

The narratives of Abraham’s sacrifice of Isaac in the Old Testament and Shun’s renunciation of the throne to save his father, who had committed a crime in Meng-Zi, have had a profound influence on Western and Chinese culture. The two stories are widely known and referenced due to their cultural significance, which is evident in various artistic, literary, religious, and philosophical forms. While the two narratives may be viewed as murder and corruption from a universal ethical standpoint, historical traditions interpret them differently. Abraham’s actions are revered as the epitome of righteousness, while Shun’s actions exemplify the most appropriate ( …

Partition Between Supercooled Liquid Droplets And Ice Crystals In Mixed-Phase Clouds Based On Airborne In Situ Observations, Flor Vanessa Maciel, Minghui Diao, Ching An Yang

Faculty Research, Scholarly, and Creative Activity

The onset of ice nucleation in mixed-phase clouds determines the lifetime and microphysical properties of ice clouds. In this work, we develop a novel method that differentiates between various phases of mixed-phase clouds, such as clouds dominated by pure liquid or pure ice segments, compared with those having ice crystals surrounded by supercooled liquid water droplets or vice versa. Using this method, we examine the relationship between the macrophysical and microphysical properties of Southern Ocean mixed-phase clouds at − 40 to 0 °C (e.g. stratiform and cumuliform clouds) based on the in situ aircraft-based observations during the US National Science …

Single-Caregiver Families: Using Lived Experiences To Build Effective Resilience And Protect Future Children Against Negative Outcomes, Andrew Chakalian

Master's Theses

Among many cited risk factors that disproportionately affect children who grow up in a single-caregiver family, adverse childhood experiences (ACEs) and related behavioral and health outcomes are some of the most significant. Comparatively, there has been a substantial gap in the research exploring protective factors that support healthy development for children with this family composition. The present study used a phenomenological methodology to explore how nine participants aged 18-25 viewed their childhood in a single-caregiver family. Through the use of semi-structured interviews, participants shared their experiences; analysis yielded four themes: (1) further dysfunction in the social system exacerbating the effects …

Observations Of Currents, Waves, And Turbulence Within A Giant Kelp Forest In Stillwater Cove, Carmel, California, Logan A. Grady

Master's Theses

Nutrient distribution and propagule dispersal within Giant kelp (Macrocystis pyrifera) forests are significantly influenced by turbulence. In-situ measurements of turbulence within giant kelp forests are limited and driving mechanisms are primarily informed by controlled-flume experiments. This study investigates relationships between currents, surface gravity waves, and turbulence within a kelp forest through deployment of moored instrumentation and kelp surveys in Stillwater Cove, California during summer of 2022. Oceanographic conditions were primarily driven by coastal upwelling and a semi-diurnal internal tide, which was associated with cooling events and enhanced onshore velocity within the kelp forest during rising tides. Estimates of gradient Richardson …

Beyond ‘Manning Up’: The Impact Of Hegemonic Masculinity & Gender Norms On Mental Health Help-Seeking Among College Men, Joslyn Barragan

Master's Theses

This narrative inquiry study was conducted to explore college men's conceptualization of masculinity and gender norms and their relationship with mental health-related help-seeking behaviors. Through semi-structured interviews with seven men, I gathered their perceptions of mental health support and the obstacles they encountered in accessing it. Drawing from Connell's conceptualization of masculinities, this study locates their narratives within the broader framework of societal expectations, highlighting the complexities of men's attitudes and behaviors toward mental health counseling. Ultimately, five critical narratives were discovered: a) Initial models of masculinity emerge through socialization; b) Men encounter barriers to mental health care from all …

Seasonal Dynamics Of The Introduced Sponge Hymeniacidon Perlevis In The Elkhorn Slough, California, Usa, Jackson Hoeke

Master's Theses

Hymeniacidon perlevis is a cosmopolitan sponge with a seasonal life cycle We investigated seasonal and interannual dynamics of H. perlevis in Elkhorn Slough estuary, where it is an introduced species, and explored correlations between sponge cover and environmental conditions. We used sponge cover to estimate the potential effects H. perlevis on its environment and how those could vary across its seasonal life cycle. We found that successful recruitment is currently restricted to the upper estuary and while it varies annually, the frequency and density of sponge recruits have generally increased from 2007 to 2023.

Flora And Fauna Lexical Indicators Of Prehistoric Movement Of Yuman Peoples, Adam Ingwerson

Master's Theses

Amyloid fibrils are locally ordered protein aggregates characterized by a filamentous morphology held together by a hydrogen bonding motif known as cross-β structure whereby hydrogen bonds form between backbone amide bond moieties across separate protein segments. The most notable medical significance of amyloid fibrils is their central role in the etiology of Alzheimer’s disease, type 2 diabetes, and other human diseases. Although amyloid fibrils have been studied extensively, the mechanism of their formation is still not fully understood. X-ray crystallography is a leading experimental technique for resolving amyloid fibril structures from crystallized proteins; however, inherent limitations leave open the possibility …

Reinforcement Learning Based Planning And Control For Robotic Source Seeking Inspired By Fruit Flies, Gauravkumar Koradiya

Master's Theses

In the exploration of mobile sensing agents such as robots equipped with sensors, these agents have the potential to measure unknown scalar fields, ranging from chemical concentrations to temperature fluctuations. One of the primary interests is the robots’ ability to gravitate towards the peaks or troughs of these fields, a phenomenon termed as “source seeking”. This behavior is invaluable in practical scenarios, like detecting chemical leaks or locating survivors after catastrophes. However, the challenge becomes significantly more pronounced when operating in turbulent flow fields, where the erratic nature of odorant plumes makes predictions and simulations highly unreliable. Interestingly, fruit flies …

Diamond as a templating substrate is largely unexplored, and the unique properties of diamond, including its large bandgap, thermal conductance, and lack of cytotoxicity, makes it versatile in emergent technologies in medicine and quantum sensing. Surface termination of an inert diamond substrate and its chemical reactivity are key in generating new bonds for nucleation and growth of an overlayer material. Oxidized high-pressure high temperature (HPHT) nanodiamonds (NDs) are largely terminated by alcohols that act as nucleophiles to initiate covalent bond formation when an electrophilic reactant is available. In this work, we demonstrate a templated synthesis of ultrathin boron on ND …

Photoinduced Charge Injection From Shallow Point Defects In Diamond Into Water, Kang Xu, Daniela Pagliero, Gabriel I. López-Morales, Johannes Flick, Abraham Wolcott, Carlos A. Meriles

Faculty Research, Scholarly, and Creative Activity

Thanks to its low or negative surface electron affinity and chemical inertness, diamond is attracting broad attention as a source material of solvated electrons produced by optical excitation of the solid-liquid interface. Unfortunately, its wide bandgap typically imposes the use of wavelengths in the ultraviolet range, hence complicating practical applications. Here, we probe the photocurrent response of water surrounded by single-crystal diamond surfaces engineered to host shallow nitrogen-vacancy (NV) centers. We observe clear signatures of diamond-induced photocurrent generation throughout the visible range and for wavelengths reaching up to 594 nm. Experiments as a function of laser power suggest that NV …

Faculty Research, Scholarly, and Creative Activity

Lentinula edodes (L. edodes) is a globally popular edible mushroom because of its characteristic sulfur-containing flavor compounds. However, the formation of the volatile sulfur-containing compounds in the mycelium of L. edodes has not been studied. We found that there were also sulfur-containing aroma compounds in the mycelium of L. edodes, and the content and composition varied at different stages of mycelial growth and development. The γ-glutamyl-transpeptidase (GGT) and cysteine sulfoxide lyase (C-S lyase) related to the generation of sulfur compounds showed the highest activities in the 15-day sample. Candidate genes for the metabolism of volatile sulfur compounds in mycelium were …
