Antipursuit,metaxydiosis, and carcinogenesis

The possibility is considered of modelling the biological processes of morphogenesis and carcinogenesis, not aetiologically but geometrically, by two kinematic processes: pursuit and antipursuit. Like morphogenesis, pursuit is stable and even self-stabilizing, while the inverse antipursuit, like carcinogenesis, may be explosively unstable. The various stability and instability features are exhibited mainly graphically. Finally, a single compound process is proposed which embraces both pursuit and antipursuit.     

Pulse mode operation of Love wave devices for biosensing applications

In this work we present a novel pulse mode Love wave biosensor that monitors both changes in amplitude and phase. A series of concentrations of 3350 molecular weight poly(ethylene glycol) (PEG) solutions are used as a calibration sequence for the pulse mode system using a network analyzer and high frequency oscilloscope. The operation of the pulse mode system is then compared to the continuous wave network analyzer by showing a sequence of deposition and removal of a model mass layer of palmitoyl-oleoyl-sn-glycerophosphocholine (POPC) vesicles. This experimental apparatus has the potential for making many hundreds of measurements a minute and so allowing the dynamics of fast interactions to be observed.
