Cardiac Catheter Brace for Minimally Invasive Surgery

Gaffney, Leah (2015-07-10)

Cardiac disease is common and many cases require invasive surgical intervention. Most cardiac surgeries, for example, require stopping the patient’s heart. A percutaneous, beating heart, catheter-based system has been ...

Convolutional Neural Networks for the Automated Segmentation and Recurrence Risk Prediction of Surgically Resected Lung Tumors

Basta, Marguerite B. (2020-06-17)

Lung cancer is the leading cause of cancer related mortality by a significant margin. While new technologies, such as image segmentation, have been paramount to improved detection and earlier diagnoses, there are still ...

The Design of a Method to Analyze the Beaks of Darwin's Finches

Strong, Elizabeth F. (2015-06-26)

Variation in beak shape among Darwin’s finches has long intrigued scientists[19][5][16]. An adage in biology is “form follows function,” or in this context, the shape of the bird beak is the result of the food available ...

Drug Refillable Vascular Grafts

Miller, Alex B. (2015-06-26)

When dealing with cardiovascular disease, vascular devices are used to expand the vascular opening and maintain proper flow. However, current vascular grafts have a high rate of occlusion due to biological responses to the ...

Hydrogel-Encapsulated Liposomes for Delivery of Therapeutic siRNA to Breast Cancer Cells

Subramanyam, Kriti S. (2015-06-26)

This project focuses on the development of a hydrogel-encapsulated liposome (‘lipogel’) delivery system for the delivery of small interfering RNA (siRNA) to breast cancer cells. siRNA-based therapeutics show promise for ...

Increasing Confidence for Stratospheric Aerosol Experiments: Improvements in Flight Turbulence Simulations to Establish Realistic Expectations for the Future Operation of SCoPEx

Chen, August Sun (2020-06-17)

Continued emissions of greenhouse gases and the absence of stringent action from global policymakers has given the world little time to combat the worst climate change has to offer. In order to give ourselves more time, ...

InGaN QD Microdisks: Experiments in Fabrication and Emission Enhancement

Mulholland, Niamh (2020-06-17)

Gallium nitride (GaN) is a material with outstanding electrical and optical properties. With it's high heat capacity and thermal conductivity, GaN has demonstrated its potential in high power electronic devices such as ...

Obstetrical Medical Device for Autotransfusion Following Life Threatening Postpartum Hemorrhage in Low-Resource Settings

Klusty, Jessica (2020-06-17)

Due to lack of safe blood supplies and other medical resources, women in low-resource areas are at a higher risk of complications from postpartum hemorrhage (PPH), a leading cause of maternal mortality. Current strategies ...

Pop-Up MEMS One-Way Endobronchial Valve for Treatment of Chronic Obstructive Pulmonary Disease

Malka, Ronit (2015-07-10)

Chronic Obstructive Pulmonary Disease (COPD) is a leading cause of morbidity in aging populations worldwide. In very severe cases of COPD arising from heterogenous emphysema, portions of diseased lung are unable to expel ...

Stable Isotope Systematics of Abiotic Nitrate and Nitrite Reduction Coupled With Anaerobic Iron Oxidation: the Role of Reduced Clays and Fe-Bearing Minerals

Grabb, Kalina C. (2015-04-08)

Under anaerobic conditions, it is widely assumed that nitrate (NO3-) and nitrite (NO2-) reduction is primarily the result of microbial respiration (Burgin and Hamilton, 2007; Granger et al., 2008). However, it is also ...
