Memory Formation In Matter, Joseph Paulsen, Nathan C. Keim, Zorana Zeravcic, Srikanth Sastry, Sidney R. Nagel

Physics - All Scholarship

Memory formation in matter is a theme of broad intellectual relevance; it sits at the interdisciplinary crossroads of physics, biology, chemistry, and computer science. Memory connotes the ability to encode, access, and erase signatures of past history in the state of a system. Once the system has completely relaxed to thermal equilibrium, it is no longer able to recall aspects of its evolution. The memory of initial conditions or previous training protocols will be lost. Thus many forms of memory are intrinsically tied to far-from-equilibrium behavior and to transient response to a perturbation. This general behavior arises in diverse contexts …


Influence Of Genetic Variation On Birth Defects In Caenorhabditis Elegans, Daniel Robert Kepple May 2013

Influence Of Genetic Variation On Birth Defects In Caenorhabditis Elegans, Daniel Robert Kepple

Honors Capstone Projects - All

In my Renee Crown Honors Capstone project, I studied how genetic variation influences birth defects that cause death in C. elegans embryos. I performed high-throughput hatching assay experiments of recombinant inbred advance intercross lines of C. elegans. These lines are genetically distinct from each other. I found significant variation in birth defects causing embryo death in these recombinant inbred advanced intercross lines. My results give evidence that gene interaction may play a significant role in causing birth defects resulting in death. My data also provides a starting point for studies making statistical arguments linking these birth defects to specific …
