In the present invention a new method for program and program verify is described. The quantified burstiness becomes a metric for determining the Quality of Service offered by a node in retransmitting data through a network. Lower layer interconnects extend along a boundary of standard cells adjacent to each other and on the boundary. This photonic device is used for treating a subject having unwanted cell proliferation, example dysplasia of the portio andor cervix with Photodynamic therapy.
