A taxonomic review of the AthetaThomsonsubgenusMicrodota Mulsant & Rey in Korea is presented. The subgenus is represented in Korea by 15 species including two new species, Atheta (Microdota) jangtaesanensis Lee & Ahn, sp. n. and Atheta (Microdota) pasniki Lee & Ahn, sp. n. Four species [Atheta (Microdota) kawachiensis Cameron, Atheta (Microdota) muris Sawada, Atheta (Microdota) spiniventris Ber...

This paper was motivated by the observation that after quickly finding a number of hierarchies (mKdV, Sawada-Kotera, Kaup-Kuperschmidt) soon after finding that KdV was integrable, nothing more was found for polynomial scalar evolution equations linear in the highest order derivative. In this paper we prove that under some mild conditions on the equations one can put a uniform bound on the order...

In this paper, a new construction of exact solutions based on the improved generalized Riccati equation mapping method with modified Reimann-Luiviile fractional derivative and symbolic computation is proposed for seeking abundant solutions of the space-time fractional fifth-order nonlinear Sawada-Kotera equation. The proposed method is very simple, direct, effective and convenient for obtaining...

vVe propose the nucleon-nucleon potential of one-boson-exchange type in the triplet even (3E) state, which is determined so as to reproduce the two-nucleon scattering data below 350 MeV as well as the deuteron data. In an earlier paper by Kishi, Sawada and Watari, the hard core radius in 3E state was larger than those in other states. In this paper we take the same hard core radius in 3E state ...

We give a syntactic view of the Sawada-Williams (σ,τ)-generation permutations. The corresponding sequence Seqn στ-operations length n!−1 is shown to have compact description size Θ(n2) in terms straight-line programs. Using description, we design almost linear time ranking and unranking algorithms.

Individual human adenoviruses (Ad) ~ vary in their tumorigenic potential in rodents. Group A serotypes induce tumors with high efficiency, while those belonging to the group C are nononcogenic (1). This phenomenon was originally thought to be a reflection of differences in their immunogenicity (2). Isograft transplantation experiments have shown, however, that immunization with both highly onco...

This paper focuses on solving the time fractional Caudrey-Dodd-Gibbon-Sawada-Kotera equation (FCDGSKE). We propose two analytical methods based complex transform, variational iteration method and homotopy perturbation method. The approximated solutions to initial value problems associated with FCDGSKE are provided without linearization complicated calculation. Numerical results show main merits...
