DOxy: A Dissolved Oxygen Monitoring System.

Dissolved Oxygen (DO) in water enables marine life. Measuring the prevalence of DO in a body of water is an important part of sustainability efforts because low oxygen levels are a primary indicator of contamination and distress in bodies of water. Therefore, aquariums and aquaculture of all types are in need of near real-time dissolved oxygen monitoring and spend a lot of money on purchasing and maintaining DO meters that are either expensive, inefficient, or manually operated-in which case they also need to ensure that manual readings are taken frequently which is time consuming.

Central retinal vein occlusion in a patient with breast carcinoma.

Systemic malignancies may have ocular manifestations in the form of metastatic tumors, carcinoma associated retinopathy or central retinal vein occlusion (CRVO). Although CRVO has been mentioned in association with renal, lung, prostatic and ovarian malignancies, the association of CRVO with breast carcinoma is unreported. We report a patient with one such rare association.

Nanodiamonds facilitate killing of intracellular uropathogenic E. coli in an in vitro model of urinary tract infection pathogenesis.

About 25-44% of women will experience at least one episode of recurrent UTI and the causative agent in over 70% of UTI cases is uropathogenic Escherichia coli (UPEC). UPEC cause recurrent UTI by evading the bladder's innate immune system through internalization into the bladder epithelium where antibiotics cannot reach or be effective. Thus, it is important to develop novel therapeutics to eliminate these intracellular pathogens.

Purification and functionalization of nanodiamond to serve as a platform for amoxicillin delivery.

Urinary tract infections (UTIs) cost $0.4-0.5 billion a year in the US and is the second most common disease affecting millions of people.

Fast and reliable collision culling using graphics hardware.

We present a reliable culling algorithm that enables fast and accurate collision detection between triangulated models in a complex environment. Our algorithm performs fast visibility queries on the GPUs for eliminating a subset of primitives that are not in close proximity. In order to overcome the accuracy problems caused by the limited viewport resolution, we compute the Minkowski sum of each primitive with a sphere and perform reliable 2.
