Preventing Memory Corruption in Chemical Computations
Professor Titus Klinge will discuss his recent work on molecular computing. Molecular computing systems that are contained in well-mixed volumes are often modeled using chemical reaction networks. In these systems, concentrations of molecules are treated as signals and used for both communication and memory storage. A common design challenge for such a system is to avoid memory corruption caused by noise in the input signals. In this talk, he overviews recent results concerning two related signal restoration algorithms for molecular systems modeled with chemical reaction networks. These algorithms are designed to prevent a memory signal from degrading over time, and he shows that under modest conditions these algorithms will maintain the memory indefinitely.
