Electromagnetic induction (EMI) systems are used for mapping the soil’s electrical conductivity in near-surface applications. EMI measurements commonly affected by time-varying external environmental factors, with temperature fluctuations being a big contributing factor. This makes it challenging to obtain stable and reliable data from measurements. To mitigate these drift effects, is customary...

In order to overcome the defects of Shuffled Frog Leaping Algorithm (SFLA) such as nonuniform initial population, slow searching speed in the late evolution and easily trapping into local extremum, a new Shuffled Frog Leaping Algorithm based on mutation operator and population diversity is proposed in this paper. The algorithm has overcome the disadvantage mentioned above. The algorithm efficie...

[1] Practical experience with the calibration of hydrologic models suggests that any single-objective function, no matter how carefully chosen, is often inadequate to properly measure all of the characteristics of the observed data deemed to be important. One strategy to circumvent this problem is to define several optimization criteria (objective functions) that measure different (complementar...

The homing endonuclease PI- Sce I consists of a protein splicing domain (I) and an endonucleolytic domain (II). To characterize the two domains with respect to their contribution to DNA recognition we cloned, purified and characterized the isolated domains. Both domains have no detectable endonucleolytic activity. Domain I binds specifically to the PI- Sce I recognition sequence, whereas domain...
