Effects Of Localized Oxygen Production By Electrolysis On The First-Generation Glucose Sensor Response, Nandita Halder

Graduate Theses and Dissertations

Glucose sensors are very important for detecting blood glucose both in vitro and in vivo. First-generation glucose biosensors were based on the glucose oxidase (GOx) enzyme using molecular oxygen as the electron acceptor and therefore oxygen dependent. Unfortunately for in-vivo work, oxygen in the body is variable and limited. Alternative approaches to overcome the oxygen dependency came with their own limitations. The widely used and commercially available ex-vivo glucose test strip uses a mediator in place of oxygen to free it from oxygen dependency. The mediator-based technology, in most cases cannot be transferred to in vivo applications due to the …

Examining The Relationship Between Library Services Use And Fall-To-Fall Retention In Community College Libraries, Eric Deatherage

Graduate Theses and Dissertations

Community college libraries exist to support institutional outcomes. One such outcome is student retention. This study’s purpose was to fill the gap in the literature at the community college level, proposing that a model including all library service use types would explain variance in student retention beyond that explained by total library financial expenditure. Services included were numbers of physical materials circulated, digital books circulated, e-serials used, reference transactions, library presentations, attendees at presentations, gate counts, and interlibrary loan materials borrowed. Additionally, it was proposed that the relationship between gate counts of physical entry into the library and student retention …

We then show an improved version, taking advantage of several system properties …

Collateral Damage: How Expanding Public Charge Policy Influences Adult Esl Enrollment, Allison M. Eckert

Master's Theses

This study used statistical analysis of enrollment records for ESL programs at community colleges throughout California from 2015-2019 to determine whether adult immigrants’ participation in public ESL programs was reduced under President Donald Trump. Immigrant families’ lesser use of public education services and means-tested federal benefits has been widely documented in the wake of Trump’s expansion of the public charge rule, which counted immigrants’ use of a wider array of public benefits against their case for residency in the United States than had any previous iteration of the rule. Failing the public charge test can block an immigrant’s entry into …

Self-Supervised Learning Disentangled Group Representation As Feature, Tan Wang, Zhongqi Yue, Jianqiang Huang, Qianru Sun, Hanwang Zhang

Research Collection School Of Computing and Information Systems

A good visual representation is an inference map from observations (images) to features (vectors) that faithfully reflects the hidden modularized generative factors (semantics). In this paper, we formulate the notion of “good” representation from a group-theoretic view using Higgins’ definition of disentangled representation [38], and show that existing Self-Supervised Learning (SSL) only disentangles simple augmentation features such as rotation and colorization, thus unable to modularize the remaining semantics. To break the limitation, we propose an iterative SSL algorithm: Iterative Partition-based Invariant Risk Minimization (IP-IRM), which successfully grounds the abstract semantics and the group acting on them into concrete contrastive learning. …
