Field Survey along Yufuin fault in Oita Prefecture, Triggered and Slipped by the 2016 Kumamoto Earthquake
Full text linkOn 16 April 2016, the earthquake (Mj 5.7) was observed in Yufuin City, Oita Prefecture, Japan. Previous studies
revealed that the earthquake was triggered by the 2016 Kumamoto Earthquake (Mj 7.3, main shock) on 16 April 2016,
and identified the Mj 5.7 earthquake-induced surface ruptures along Yufuin fault. On 7 August, 2024, we conducted field
survey along the fault and tried to identify traces of the ruptures at the two sites, where phase discontinuity was interpreted
in the InSAR (synthetic aperture radar interferometry) image observed between 7 March 2016 and 18 April 2016. Howev
er, we could not identify the clear traces of the ruptures.departmental bulletin pape
Symmetry and Entropy of Bio-Macromolecules I Equi-partition of twenty kinds of aminoacyl-tRNA synthetases
Full text linkThe partition of aminoacyl-tRNA synthetases (aaRSs) into two classes of equal size and the correlated amino acid dis
tribution is a puzzling still unexplained observation. We propose that the time scale of the amino-acid synthesis，assumed
to be proportional to the number of reaction steps (N
E
) involved in the biosynthesis pathway，is one of the parameters
that controlled the timescale of aaRSs appearance. Because all pathways are branched at fructose-6-phosphate on the met
abolic pathway，this product is defined as the common origin for the N
E comparison. For each amino-acid，the N
E value，
counted from the origin to the final product，provides a timescale for the pathways to be established. An archeological
approach based on N
E reveals that aaRSs of the two classes are generated in pair along this timescale. The results support
the co-evolution theory for the origin of the genetic code with an earlier appearance of class II aaRSs.departmental bulletin pape
