Spd: Shallow Backdoor Protecting Deep Backdoor Against Backdoor Detection, Shunjie Yuan, Xinghua Li, Xuelin Cao, Haiyan Zhang, Mengyao Zhu, Robert H. Deng

Research Collection School Of Computing and Information Systems

Backdoor attacks have revealed the vulnerability of deep neural networks (DNNs), which motivates the development of secure deep learning systems. However, existing backdoor attacks often fail to bypass backdoor detection and human visual inspection, resulting in the exposure of the backdoor implanted in DNNs, which can subsequently be significantly mitigated through pruning or fine-tuning on benign data. To address this issue, in this paper, we propose a novel backdoor attack called SPD (Shallow Protecting Deep), which consists of a deep backdoor in the frequency domain and a shallow backdoor in the pixel domain, where the shallow backdoor acts as a …

Morphology-Aware Hrv Estimation From Wrist Ppg In Sedentary Scenarios, Changshuo Hu, Hung Manh Pham, Dong Ma

Research Collection School Of Computing and Information Systems

Photoplethysmography (PPG) is widely used in wearable devices for non-invasive heart rate variability (HRV) monitoring. While most prior work focuses on mitigating motion artifacts, recent studies highlight that even subtle contact pressure variations can distort waveform morphology and lead to inaccurate HRV estimates. In this work, we propose a morphology-aware deep learning framework that conditions HRV estimation on beat-level waveform types. Our model jointly encodes the raw PPG waveform and a sequence of pressure-induced morphology labels using parallel encoders, integrates them via cross-attention, and predicts normal-to-normal (NN) intervals and beat count to support downstream HRV computation. Evaluated on the public …

Developing A Strong Cps Defender: An Evolutionary Approach, Qingyuan Hu, Christopher M. Poskitt, Jun Sun, Yuqi Chen

Research Collection School Of Computing and Information Systems

Cyber-physical systems (CPSs) are used extensively in critical infrastructure, underscoring the need for anomaly detection systems that are able to catch even the most motivated attackers. Traditional anomaly detection techniques typically do `one-off' training on datasets crafted by experts or generated by fuzzers, potentially limiting their ability to generalize to unseen and more subtle attack strategies. Stopping at this point misses a key opportunity: a defender can actively challenge the attacker to find more nuanced attacks, which in turn can lead to more effective detection capabilities. Building on this concept, we propose Evo-Defender, an evolutionary framework that iteratively strengthens CPS …

Eeg And Media Multitasking: Adhd As A Moderating Factor, Xiaoying Guo

Theses and Dissertations

Media use has become an integral part of everyday life. It has risen dramatically over the past century with the advent of television, computers, and digital platforms, and more recently, it has been characterized by individuals using multiple devices simultaneously (Bushman & Anderson, 2001; Nielsen Media Research, 1998; Rideout & Robb, 2019, 2021). Media multitasking (MMT) has been linked to cognitive control challenges and attentional difficulties. This study examined EEG workload (Fz theta/Pz alpha ratio), survey accuracy, and ADHD traits (ASRS v1.1) in 33 adult participants across baseline and single-versus dual-media conditions. Results indicated that mental workload was significantly higher …

The Efficacy Of Emdr Therapy Compared To Tf-Cbt In Adopted Children To Manage Post-Traumatic Stress: An Integrative Review, Grace Ann Steiner

Senior Honors Theses

This integrative review examines the efficacy of eye movement desensitization and reprocessing (EMDR) therapy compared to trauma-focused cognitive behavioral therapy (TF-CBT) in managing post-traumatic stress disorder (PTSD) in adopted children. Children adopted from foster care tend to experience more adverse childhood experiences (ACEs) and maladjustment issues when compared to the general population, which necessitates effective therapeutic interventions to reduce PTSD symptoms and emotional dysregulation. Through analysis and comparison of the data, it was determined that both EMDR and TF-CBT effectively alleviated trauma-related symptoms, although one technique is not necessarily always more effective or efficient than the other. Along with reviewing …

Characterization Of Mannosidases (Man) In Tetrahymena Thermophila Using Bioinformatics Tools, Cynthia Wen

Publications and Research

Mannosidases are a type of glycoside hydrolase (glycosidase) that facilitate the hydrolysis of glycosidic bonds in mannose-containing polysaccharides and glycans, including those found in glycoproteins. Their main role is to cleave specific linkages involving D-mannose residues, effectively trimming or degrading mannose-rich oligosaccharides. These enzymes are crucial in N-glycosylation pathways, which are essential for proper protein folding, glycoprotein maturation, and the regulation of carbohydrate metabolism in eukaryotic cells.

There are two main types of mannosidases: alpha-mannosidases and beta-mannosidases. In humans, several of these enzymes exist, including those found in the endoplasmic reticulum (alpha-mannosidase I), those in the Golgi apparatus (alpha-mannosidase II), …

Two Moles, Two Worlds: Network Analysis Of Infernal Affairs And The Departed, Melissa Vu

IPHS 200: Programming Humanity

This project aims to explore how adaptation reshapes the social architecture of a movie. To do this, I used social network analysis to compare the character dynamics between Infernal Affairs(Hong Kong, 2002) and its U.S. adaptation The Departed(2006) in two ways: co-presence networks (characters connected when they appear in the same scene, with edge weights capturing repeated co-appearance) and directed dialogue network (arrows representing who speaks to whom, with thicker arrows indicating more frequent dialogue). Comparing the network structures across the two films reveals meaningful differences in group structure, connecting roles, and the concentration of dialogue around key characters, which …

Bone Marrow Endosteum In Homeostasis And Metastasis, Yuta Nakai, Wanida Ono, Noriaki Ono

Faculty, Staff and Student Publications

The endosteum is a thin layer of connective tissue lining the inner surfaces of bones adjoining the medullary cavity. The endosteum houses a variety of cells crucial for bone growth, repair and remodelling, including bone-forming osteoblasts, bone-resorbing osteoclasts and their precursor cells. Historically, the endosteum has been extensively studied as a key site for haematopoiesis by which blood cells are incessantly produced. However, recent studies have defined the endosteum as a niche for skeletal stem cells, underscoring the importance of the harmony between the inner endosteum and the outer periosteum in maintaining bone homeostasis. The endosteum also plays a significant …

The Fear Factor: Exploring The Experiences Of Fear Of Secondary School Teachers, Kelly J. Raines

Doctor of Education (Ed.D)

Fear can be a powerful catalyst for cognitive potential, or a potent agent of havoc. This descriptive (transcendental) phenomenological study aimed to understand the phenomenon of fear experienced by teachers in public and private secondary schools in Central Florida. Semi-structured interviews collected data from the purposive sample, and the data were thoroughly analyzed using Colaizzi's (1978) model. The emergent essence of the lived experience of teachers identified the phenomenon of fear as the inducement of a debilitating sense of powerlessness that diminishes self-confidence and self-efficacy, resulting in emotional, cognitive, and/or physical impairments that directly affect the metacognitive potential of teachers. …

How The Billable Hour Can Survive Generative Ai, Jonah Perlin

Georgetown Law Faculty Publications and Other Works

The legal profession is rapidly adopting generative AI technology. With this shift has come an increasingly common assumption that generative AI will significantly reduce or even bring an end to hourly billing. The logic underlying this conclusion seems intuitive: if AI reduces the time lawyers spend on certain tasks while eliminating others altogether, then the total number of billable hours will fall. That decline, in turn, could threaten the financial viability of hourly billing, despite its place as the dominant law firm compensation model over the past half century.

This Article challenges this assumption. It argues instead that the billable …

Attribution As Architecture In The Digital Age, Laura A. Heymann

Faculty Publications

As technology changes, one thing remains constant: human creators seem to care about attribution, whether as creators or as audience members. Current U.S. law lacks the means for many creators to effectively address attributional interests, and experience has shown that top-down, imposed technological solutions can fail to gain the necessary buy-in and adoption. The best approach, examples suggest, is for platforms to think of attribution as part of the architecture of their systems, but to take their cues from user-developed, individualized solutions, which will not only be more responsive to user interests but also allow adaptation as interests change and …

Attachment Styles Connection To Teacher Burnout, Erica Jaeschke

Master's Theses & Capstone Projects

Teacher burnout has become a concern, as teachers are leaving the classroom more frequently than in the past. A teacher's attachment may be associated with the development and persistence of teacher burnout. The problem with this topic is that teachers are leaving the classroom at alarming rates, which is problematic because schools will not have the support they need to educate future generations. This study aims to determine whether teacher burnouts are associated with specific attachment theories. A quantitative method was employed through voluntary survey questions, and 18 teachers participated.
