The flathead catfish Pylodictis olivaris is a large piscivorous carnivore that has been widely introduced beyond its native range. I studied the behavior of a flathead catfish population that has recently inhabited a section of the Deep River, North Carolina (in the upper Cape Fear River basin), and currently coexists with the federally endangered Cape Fear shiner Notro....

We propose a new procedure for estimating the survival function of a time-to-event random variable under arbitrary patterns of censoring. Under mild smoothness assumptions, this procedure allows a unified approach to handling different kinds of censoring, while in many cases increasing efficiency. Our approach uses a seminonparametric (SNP) density to represent the dens....

Mechanical stimulation of tissue cells is a popular technique used by tissue engineering researchers to stimulate cell growth. This research requires an instrument that applies in-vitro compression and tension to individual cells, through mechanical loading. The mechanical load in the research reported on here is generated using a vacuum system under ....

RUCHIR GUPTE. Interval Arithmetic Logic Unit for DSP and Control Applications. (Under the direction of Prof. William W. Edmonson). There are many applications in the field of digital signal processing (DSP) and controls that require the user to know how various numerical errors (uncertainty) affect the result. Interval Arithmetic (IA) eliminates this uncertainty by repl....

In this thesis we present a formal study of the following view-selection problem: Given a set of queries, a database, and an upper bound on the amount of disk space that can be used to store materialized views, return definitions of views that, when materialized in the database, would reduce the evaluation costs of the queries. Optimizing the layout of stored data using....

Nkx3.1 is a homeodomain-containing transcription factor that is expressed early in the development of the prostate gland and is likely to play an important role in the differentiation of prostatic epithelia. Loss of Nkx3.1 protein expression is often an early event in prostate tumorigenesis, and the abundance of Nkx3.1-negative epithelial cells increases with disease pr....
