    • An ex-core nuclear instrumentation system in which the width of measurable neutron detector current can be accurately widened is obtained. In order to output the condition of neutron flux in operation by performing arithmetic processing of a current value measured by a neutron detector by using a detector signal processing circuit, the detector signal processing circuit includes a current/voltage conversion unit which converts the current value converted by the neutron detector into a voltage value corresponding to the current value; and a variable gain amplification unit which has an operational amplifier having a resistance circuit for corresponding to current levels, the resistance circuit being capable of selecting a gain, and a D/A converter that adjusts the gain, and amplifies the voltage value converted by the current/voltage conversion unit.

    • Assuming frame F having specific short length L2 on a transcript, a structure in a small-section is sequentially analyzed while shifting the frame F finely in a step-like manner by constant value t, and first probability for a specific secondary structure in a specific position in each small-section is determined. Then, at least one specific position proved in each small-section is arranged in corresponding position on the original transcript, and the magnitude of degree of overlapping between the specific positions is determined as second probability. By focusing on these two probabilities, it is possible to predict whether an intended secondary structure is actually present in RNA such as mRNA with higher reliability.
