Towards A Fully Nonlinear Cauchy Characteristic Extraction, Maria Babiuc-Hamilton

The artificial finite outer boundary present in Cauchy codes introduce two sources of error: The outer boundary condition and waveform extraction at an inner worldtube. The problem of proper boundary condition for a radiating system can be solved only by extension to Ι+ (conformal compactification). Cauchy Characteristic Extraction (CCE) offers a means to avoid these errors.

The fold of the β-helical antifreeze protein from Tenebrio molitor (TmAFP) proved to be surprisingly tolerant of multiple amino acid substitutions, enabling the construction of a panel of mutants displaying grids of single amino acid types in place of the threonines on the ice-binding face. These mutants, maintaining the regularity of amino acid spacing found in the wild-type protein but with different functional groups on the surface, were tested for antifreeze activity by measuring thermal hysteresis and observing ice grown in their presence. We found that no mutant exhibited the dramatic activity of the wild-type version of this hyperactive antifreeze …
