Seizure Prediction In Epilepsy Patients, Gary Dean Cravens

NSU REACH and IPE Day

Purpose/Objective: Characterize rigorously the preictal period in epilepsy patients to improve the development of seizure prediction techniques. Background/Rationale: 30% of epilepsy patients are not well-controlled on medications and would benefit immensely from reliable seizure prediction. Methods/Methodology: Computational model consisting of in-silico Hodgkin-Huxley neurons arranged in a small-world topology using the Watts-Strogatz algorithm is used to generate synthetic electrocorticographic (ECoG) signals. ECoG data from 18 epilepsy patients is used to validate the model. Unsupervised machine learning is used with both patient and synthetic data to identify potential electrophysiologic biomarkers of the preictal period. Results/Findings: The model has shown states corresponding to …

Understanding Of Aerosol Transmission Of Covid 19 In Indoor Environments, Adama Barro, Cathal O'Toole, Jacob S. Lopez, Matthew Quinones, Sherene Moore

Publications and Research

Our reason for discussing severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) or 2019 novel corona virus (Covid-19), is to understand its aerosol transmission characteristics in indoor spaces and to mitigate further spread of this disease by designing a new HVAC system. The problem that we are tackling is the spread of covid-19 droplets through aerosol transmission by looking at potential engineering solutions to the existing HVAC systems. The purpose is to eradicate the spread of the COVID-19 by testing indoor spaces in an effort to understand the effectiveness of ventilation controls. We believe that scientists and engineers have not …

Thermal Analysis Of Borosilicate Glass For Its Biological Applications, Gregory Humble

Symposium of Student Scholars

Borosilicate glass doped with varying wt% of cerium oxide is investigated for biological applications. Thermal studies of each formulation were conducted using an SDT Q600 differential scanning calorimeter. 30mg samples of 350 - 425 μm particle size of each type of glass were heated to 1200°C in order to obtain the glass transition, crystallization, and melting temperatures. Samples were then heated to 900°C at several heating rates, ranging from 2°C/min to 100°C/min, then compared against each other as well as against an undoped borosilicate glass.

Powers Of Ten: From Meters To Nanometers And Beyond, Rob Snyder

Nanotechnology Teacher Summer Institutes

The goal of this activity is to guide students toward an understanding of nanoscale dimensions by:

• Making a number of measurements using meter sticks, magnifiers, microscopes and spectrometers so students can make observations and generate their own data.

• Using scientific notation to compare the measurements they have made with the dimensions of very small structures

Using Adi To Quantify A Color Change In Crayfish, Jennifer Welborn

Do Crayfish Change Color If Their Environment Changes? A Guided Inquiry Lab for 7th grade Life Science

Background: There is anecdotal evidence from bass fisherman that crayfish are able to change color depending on their surroundings. A (cursory) literature review of this phenomenon showed that no formal research has been done in this area. Students had an additional informal lesson about research funding (or lack thereof) because of this finding.

Students designed and conducted a controlled experiment to see the effect of changing environment color on crayfish color.

ADI was used to quantify a color change.
