Cells navigate environments, communicate and build complex patterns by initiating gene expression in response to specific signals. Engineers seek to harness this capability to program cells to perform ...

Analog circuit design is increasingly encountering mixed-signal circuits, and analog engineers need some understanding of discrete-time sampling circuits, whether they are sample-and-hold circuits or ...

SPICE has been the mainstay tool for analog and RF designers for over 25 years. During that time, analog- and RF-circuit complexity has grown by several orders of magnitude while circuit geometries ...

Synthetic gene circuits are designed to implement novel biologic function, including cellular logic, dynamics and complex cellular and multicellular behaviours. A decade after emerging as a discipline ...
