Effect Of Using The Snackability Smartphone Application To Improve The Quality Of Snack Intake, General Diet Quality, And Weight Among College Students, Lukkamol Prapkree

FIU Electronic Theses and Dissertations

College is a challenging period to make healthy food and snack choices and this could lead to poor diet quality and weight gain in the future. The Snackability application (app) was developed using the Social Cognitive Theory for behavior change to help students choose healthy snacks based on the USDA guidelines. The objective of this study was to determine whether the app improved snack, diet quality, and body weight in overweight and obese college students within a two-arm, 12-week randomized controlled trial (RCT). A total of 139 participants completed all baseline measures and were randomized into the control or app …

A Machine Learning Framework For Identifying Molecular Biomarkers From Transcriptomic Cancer Data, Md Abdullah Al Mamun

FIU Electronic Theses and Dissertations

Cancer is a complex molecular process due to abnormal changes in the genome, such as mutation and copy number variation, and epigenetic aberrations such as dysregulations of long non-coding RNA (lncRNA). These abnormal changes are reflected in transcriptome by turning oncogenes on and tumor suppressor genes off, which are considered cancer biomarkers.

However, transcriptomic data is high dimensional, and finding the best subset of genes (features) related to causing cancer is computationally challenging and expensive. Thus, developing a feature selection framework to discover molecular biomarkers for cancer is critical.

Traditional approaches for biomarker discovery calculate the fold change for each …
