Hybrid Machine And Deep Learning Framework For Secure Fog-Based Vanets, Hadeer Kamal, Amira Y. Haikal, Mahmoud M. Saafan Dec 2025

Hybrid Machine And Deep Learning Framework For Secure Fog-Based Vanets, Hadeer Kamal, Amira Y. Haikal, Mahmoud M. Saafan

Mansoura Engineering Journal

As a conventional implementation of intelligent transportation systems (ITS), a Vehicular Ad-hoc Network (VANET) facilitates smart communication between vehicle nodes and network infrastructures. Nevertheless, the distributed and dynamic characteristics of VANETs make them vulnerable to numerous cyberattacks like DOS and spoofing. Rapid detection of these threats is crucial. It is essential to respond promptly to mitigate threats before they impact vehicle coordination or infrastructure functionality. In this context, fog computing presents an effective solution. Transferring computational tasks from centralized cloud servers to fog nodes allows for quicker detection within the VANET environment. This research utilizes computational resources for swift and …

Face Value: A Computational Approach To Subjective Impressions Of Faces, Kevin Kpankou Dec 2025

Face Value: A Computational Approach To Subjective Impressions Of Faces, Kevin Kpankou

Undergraduate Research Symposium

Various computational models of first impressions have been developed to uncover the mechanisms driving these judgments. However, the implicit notion of a singular ``human'' often overlooks meaningful individual differences in beliefs, attitudes, and associations, as well as culturally grounded group-level constructs. In this paper, we extend Cultural Consensus Theory (CCT) to estimate culturally shared beliefs about faces by incorporating latent constructs structured around interpretable facial features extracted via computer vision algorithms. We apply our model to a large-scale dataset of people’s first impressions of faces. Our approach reveals a robust mapping between facial features and culturally constructed impressions, allowing us …

Targeting Pancreatic Cancer With Rapamycin-Loaded Gold Nanoparticles Conjugated To Egf Peptide: Studies On Cytotoxicity And Uptake Mechanisms Aided By Proteomic Analysis, Adeolu Oluremi Dec 2025

Targeting Pancreatic Cancer With Rapamycin-Loaded Gold Nanoparticles Conjugated To Egf Peptide: Studies On Cytotoxicity And Uptake Mechanisms Aided By Proteomic Analysis, Adeolu Oluremi

Theses and Dissertations

Pancreatic cancer remains one of the most lethal malignancies, with a five-year survival rate below 5%. While rapamycin (Rap) has demonstrated therapeutic potential, its clinical utility is hampered by systemic toxicity. To address this limitation, this study developed a targeted nanocarrier system using gold nanospheres (AuNPs) functionalized with the Epidermal Growth Factor Receptor (EGFR) peptide GE11 for the specific delivery of Rap to pancreatic cancer cells. It is to note that pancreatic cancer overexpresses EGFR. The AuNP–GE11–Rap conjugates were successfully synthesized and characterized using physico-chemical techniques, which confirmed peptide conjugation and drug loading. In vitro studies using PANC-1 cells demonstrated …

The Role Of Attention And Design In The Effectiveness Of Eco-Feedback Systems, Lyndsey Bentzoni Dec 2025

The Role Of Attention And Design In The Effectiveness Of Eco-Feedback Systems, Lyndsey Bentzoni

Best Integrated Writing

This paper examines the role of eco-feedback systems in promoting pro-environmental behaviors by providing users with easily accessible information about their resource consumption. While these systems have shown potential to reduce consumption, they can face difficulties in maintaining user engagement and achieving long-term behavior change. There are several key factors related to the design of feedback interfaces that influence the effectiveness of eco-feedback systems. Gamification has been proposed as an effective way to enhance user engagement but requires careful design to connect behaviors from the digital to the real space for learning transfer. Research on the long-term usage of these …

Energy Input–Output Meta-Analysis Reveals Algal Diesel Struggles To Break Even, Michelle M. Arnold, David J. R. Murphy, Christopher L. Lant Dec 2025

Energy Input–Output Meta-Analysis Reveals Algal Diesel Struggles To Break Even, Michelle M. Arnold, David J. R. Murphy, Christopher L. Lant

Environment and Society Student Research

Algal biofuels have been investigated as an alternative to fossil fuels and first-generation biofuels for transportation in the United States since the 1970s. Yet after five decades of development, scalability and implementation remain limited—largely due to persistent barriers such as low biomass productivity, modest lipid yields, and energy-intensive processing methods. These technical challenges significantly constrain the feasibility of large-scale commercialization despite substantial research and investment. To evaluate progress toward commercial viability, this study harmonized energy inputs and outputs across 508 observations on the production of algal biofuel energy return on energy investment (EROEI) in the United States. While bioethanol achieves …

Dna Tetrahedron-Au Nps-Go For Enhanced Fluorescence Detection Of Serotonin, Zhang Yun, Wu Qiong, Gao Hui, Zhang Hua, Miao Xiang-Min Dec 2025

Dna Tetrahedron-Au Nps-Go For Enhanced Fluorescence Detection Of Serotonin, Zhang Yun, Wu Qiong, Gao Hui, Zhang Hua, Miao Xiang-Min

Journal of Food and Drug Analysis

Evidence had accumulated that serotonin (5-HT), a hormone and neurotransmitter, was not only involved in a variety of different physiological and central nervous system functions but also in the development and manifestation of psychiatric diseases. Here, DNA tetrahedron-Au NPs-GO for enhanced fluorescence sensor was designed for detecting serotonin. Au NPs-GO was used as a fluorescence quencher, while fluorophore-labeled DNA tetrahedron was used as a donor, resulting in fluorescence resonance energy transfer (FRET) from the fluorophore to Au NPs-GO (signal off). With the strong binding ability of aptamer to serotonin, S5 was released from Aptamer: S5 duplex, then reacted with the …

Targeting Chemical Carcinogenesis: Α-Pinene And D-Limonene As Chemopreventive Agents Against Nnk/ Tcdd- And Urethane-Induced Lung Tumorigenesis, Kuo-Ching Huang, Vui-Hyen Chew, Yu-Ying Chen, Huey-Jen Su, Hao-Ting Chang, Rong‑Jane Chen, Ying‑Jan Wang

Journal of Food and Drug Analysis

Lung cancer is the leading cause of cancer-related deaths worldwide, driven by carcinogens such as tobacco-derived nitrosamines, dioxins, and urethane. This study evaluated the chemopreventive effects of two monoterpenes, α-pinene and D-limonene, using NNK/TCDD- and urethane-induced lung tumor models and A549 lung cancer cells. Both compounds significantly reduce tumor number and size, with enhanced effects when combined. Mechanistic studies revealed suppression of PRC1, β-catenin, and c-Myc, alongside activation of p53, Bax, and caspase-3, indicating inhibition of the PRC1—Wnt/β-catenin pathway and induction of apoptosis. These findings suggest α-pinene and D-limonene as safe, promising agents for lung cancer chemoprevention.

Rab32c Mediates Osmoregulation And Calcium Homeoastasis In Dictyostelium Discoideum, Ashley Esparza

Theses and Dissertations

Vesicular trafficking is a fundamental process essential to cell viability and dictates roles in both cellular and tissue function in multicellular organisms. To further understand various vesicular trafficking processes, our lab focuses on the moderators of these processes, Rab GTPases, using the model organism Dictyostelium discoideum. This dissertation focuses explicitly on the uncharacterized protein Rab32C, a homolog of human Rab32. While several Rab family members have been well defined, the functionality of Rab32C remains poorly understood.

Fabrication Of Three-Dimensional Seaweed-Based Scaffolds And Evaluation Of Cell Attachment And Viability For Cultured Meat Applications, Srishti Tandon

Honors Scholar Theses

Global demand for animal protein is increasing rapidly, underscoring the need for sustainable meat production. Cultured meat is a promising alternative to traditional meat production techniques, but it requires optimization before it can be implemented on a large scale. Scaffolds are an important component for making cultured meat, as they provide structural support for cell attachment and mimic the texture of meat. Scaffolds need to be biocompatible, mechanically supportive, and biochemically active to promote proper cell adhesion, proliferation, and differentiation. This project investigated brown seaweed extract (SWE) hydrogels as a scaffold for cultivated meat applications and compared their mechanical and …
