Enhanced Breast Cancer Tumor Classification Using Mobilenetv2: A Detailed Exploration On Image Intensity, Error Mitigation, And Streamlit-Driven Real-Time Deployment, Aaditya Surya, Aditya Keshary Shah, Subash Tarun Sasikumar, Jarnell Kabore

Butler Journal of Undergraduate Research

This research introduces a sophisticated transfer learning model based on Google’s MobileNetV2 for breast cancer tumor classification into normal, benign, and malignant categories, utilizing a dataset of 1576 ultrasound images (265 normal, 891 benign, 420 malignant). The model achieves an accuracy of 0.82, precision of 0.83, recall of 0.81, ROC-AUC of 0.94, PR-AUC of 0.88, and MCC of 0.74. It examines image intensity distributions and misclassification errors, offering improvements for future applications. Addressing dataset imbalances, the study ensures a generalizable model. This work, using a dataset from Baheya Hospital, Cairo, Egypt, compiled by Walid Al- Dhabyani and colleagues (2020), emphasizes …

National Youth Advocacy and Resilience Conference

"Success Is the Only Option". Reflective, Engaging, Imperative. Often times teachers place grades on report cards without analyzing or reflecting. Interesting conversations take place when teachers are presented with a chart displaying the number of As and Bs compared to the number Ds and Fs. What does a snapshot of your classroom, school, or district reveal about both student and teacher academic success? This presentation allows participants to identify resolutions to barriers, as well as receive tools that enhance student/teacher engagement - as Academic Success Is the Only Option.

UMSL Datasets

The UMSL OER Open Dataset is a collection of data pertaining to Affordable and Open Educational Resources (OER) courses offered at the University of Missouri-St. Louis (UMSL). The dataset includes information such as course names, IDs, instructors, meeting patterns, enrollment numbers, and more. This dataset is not exhaustive, but it does include a helpful data dictionary to help orient researchers, educators, and students to better utilize the dataset to explore potential student cost savings and patterns in affordable and OER course offerings at the University of Missouri-St. Louis.

Easy, Bright, Fluorescence Demonstration Of Buffer Action, Mariana Dykstra, Yejin Chung, Mark Muyskens

University Faculty Publications and Creative Works

We report an attractive update to the demonstration of acid–base buffer action that is appropriate for ease of use and getting attention in the classroom. The twist is based on new fluorophore information and the recent availability of UV flashlights serving as an ideal, portable excitation light source. The pH-dependent fluorescence comes from a choice among three natural sources, namely narra tree wood extract, kidneywood extract, and scopoletin, which is a purchasable coumarin, that all perform equally well. We provide practical details for performing the buffer demonstration at scales of 100 and 1000 mL and give background information for context.
