Title: Texture Classification on Uneven Surfaces: Using Deep Learning Techniques

Maliheh Marzani

Robots are increasingly vital across various fields, and enhancing them with human-like touch capabilities opens new functional possibilities. Tactile sensors enable robots to perceive and interact with their surroundings similarly to humans. This research focuses on utilizing tactile sensors to classify textures on uneven surfaces, a novel area not extensively covered before. Our methodology involves collecting data points along set paths on an object's surface to create a trajectory for tactile data collection, reducing assumptions about the surface's geometry and enhancing adaptability.

A sliding window approach is used to analyze texture features, segmenting data into smaller, overlapping windows to improve accuracy and reduce computational load. The dataset from uneven surfaces is complemented with data from even surfaces obtained from another study. Advanced deep learning models, including 1D convolutional neural networks (CNNs) and bidirectional long short-term memory (LSTM) networks, are applied for classification. These models achieve high performance, with accuracy, precision, and recall rates of 92.3% for uneven surfaces and higher rates for even surfaces.

This research highlights the importance of integrating tactile sensing into robotics for better texture classification on uneven surfaces. By using bio-inspired sensors like MARG and barometers, the study enhances robotic tactile sensing and addresses the challenge of interacting with varied environments, paving the way for advanced applications requiring precise tactile perception.

Title: Role of Survivin and Sirtuin-1 in Antioxidant & Redox Response in ARPE-19 Cells

Summary: This study aims to investigate the role of oxidative stress and the ability to use natural antioxidant compounds as a means of reducing oxidative stress and mitigating further cellular damages in an in vitro model of age-related macular degeneration. Resveratrol, pterostilbene, lutein, punicalagin, loganin, chebulagic acid, beta-carotene, and zeaxanthin were investigated in the cell culture model as a means of offering cytoprotection to ARPE-19 in environments of chronic oxidative stress. The study used engineered CRISPR Knockdown cells to investigate the response of antioxidants on survivin and sirtuin-1 reduced human retinal cells (ARPE-19 cells).

Committee Members: Dr. Neelam Khaper (supervisor), Dr. Christine Gottardo, Dr. Zach Suntres, and Dr. Guangdong Yang (external)

Book Launch ---- Radical Food Geographies: Power, Knowledge and Resistance

Event Date: 
Thursday, September 12, 2024 - 5:00pm to 7:00pm EDT
Event Location: 
Online: Link provided after RSVP
Event Fee: 
Free

Join The Food Studies Program at The New School for presentations and participatory discussion of the new book “Radical Food Geographies: Power, Knowledge and Resistance” (2024 Bristol University Press)! This collection, co-edited by Colleen Hammelman, Charles Z. Levkoe, and (Food Studies Program Chair) Kristin Reynolds, presents critical and action-oriented approaches to addressing food systems inequities across places, spaces, and scales from around the world. 

The praxis of “radical food geographies” connects three intersecting elements: 1) theoretical engagement with power and structures of oppression both inside and outside the academy; 2) action through academic, social movement, and civil society collaborations; and 3) analysis through a broadly defined geographic lens. With case studies from Indigenous territories, Palestine, India, South Africa, Chile, and the Guatemala/Honduras highlands, as well as the United States and Canada, Radical Food Geographies explores interconnections between power structures and the social and ecological dynamics that bring food from the land and water to our plates. Through themes of scale, spatial imaginaries, and human and more-than-human relationships, the authors explore ongoing efforts to co-construct more equitable and sustainable food systems for all. Advancing a radical food geographies praxis, the book reveals multiple forms of resistance and resurgence, and offers examples of co-creating food systems transformation through scholarship, action, and geography.

In this hybrid (in-person and online) event, the co-editors will introduce the book and the collective process that led to its publication, followed by short presentations by several book chapter authors and audience discussion. A reception will follow (for in-person attendees).

Title - Design, Synthesis, and Evaluation of Novel Aurora Kinase Inhibitors for Cancer Diagnosis and Therapy

Cancer remains the second leading cause of death globally, with advancements in diagnosis and therapeutics playing a crucial role in improving patient outcomes. Aurora kinases, as essential mitotic regulators, have been key targets in cancer treatment due to their oncogenic properties. Despite the development of various selective and pan-Aurora inhibitors demonstrating effective antitumor properties in preclinical studies, none have been approved for human use. The need for novel, highly selective inhibitors is critical for advancing cancer therapy and understanding the biological functions of Aurora kinases. Aurora kinase A, B, and C, though structurally similar, differ in subcellular locations and cancer-specific amplification. Inhibiting Aurora A poses risks of secondary tumors, whereas targeting Aurora kinase B with selective inhibitors offers a less toxic strategy. This research focusing on the most potent Aurora B inhibitor, Barasertib, has revealed that enhancing specific residue interactions could improve selectivity for Aurora B over A. Further developments led to a new inhibitor with high selectivity for Aurora B and significant anticancer activity against HPV-positive cervical cancer cell lines. Additionally, efforts to create potent 18F-radiotracers for cancer imaging have shown improved binding affinity. The structural selectivity mechanism of the first Aurora C inhibitor, HCE0063, aids in distinguishing between Aurora B and C due to their phenotypic similarities. An overview of cancer metastasis, its cellular and molecular mechanisms, and recent advances in anti-metastatic strategies were also discussed. This research enhances the understanding of Aurora kinase inhibitors' structural selectivity and therapeutic potential, paving the way for the development of highly selective and potent inhibitors for cancer diagnosis and treatment.
