A Comparison of Physical Random Number Generators
Logan Francis (2014)
Good random number generators (RNGs) are required for many applications in science and industry. Random numbers can be created in two ways: with a computer algorithm known as a pseudo-random number generator (PRNG), or by measuring physical phenomena which behave randomly, such as quantum mechanical or chaotic systems. However, PRNGs are deterministic in nature and cannot produce truly random output, while physical RNGs can. Three physical RNGs were constructed: a Chua circuit, an electrical circuit which exhibits chaos; an avalanche circuit, which produces a noisy electrical signal; and a radioactive decay counter. Each RNG produced output in the form of ASCII files containing 0s and 1s. The randomness of the data was assessed using the open source statistical test suite rngtest.

Alzheimer's Disease: Are Certain Parts of Memory More Affected by Alzheimer's Disease Than Others?
Julia Mahoney (2012)
Alzheimer’s Disease (AD) is a form of dementia that affects a person’s cognitive ability. It is characterized by the rapid decline of cognition. The first case of AD was reported in 1907 but, even 100 years later, very little is known about the cause of the disease.

Microflora of the Human Gastrointestinal Tract
Rebecca Kennedy (2011 Winter)
The human body plays host to a large and diverse group of microbial inhabitants. The intestinal system is certainly no exception.
