A method is provided comprising reading a set of memory cells indicating whether stored redundancy information is reliable and, if the set of memory cells indicates that the stored redundancy information is reliable, determining whether to read primary memory or redundant memory based on the stored redundancy information. The inverter generates a first minimum voltage having a smaller feedback voltage of a plurality of feedback voltages and compares the first minimum voltage and a short circuit reference voltage to determine a short circuit of at least two discharge lamps. The piezoelectric thin film formed by this operation is of a polycrystalline structure. The first and second messages are stored, and the first message is sent upon receiving an order to send the first message and the second message is sent upon receiving an order to send the second message. The invention also relates to progeny corn plants having this event. Generating the refined distribution may include, for example, selecting values of the fracture parameter from fracture pattern models that correlate with the microseismic event data.
