A new method of trajectory planning for robot manipulators is proposed, in which the reference in joint space is expressed as a B-spline curve, and is optimized by the variational method. This has an… (More)

Including the vacuum effects, the compressional properties of nuclear matter are studied in the cutoff field theory. Under the Hartree approximation, the low-energy effective Lagrangian is derived in… (More)

Based on quantum hadrodynamics with a finite cutoff, the effective masses of vector mesons(ω, ρ) in nuclear medium are calculated. We use a low-energy effective Lagrangian which is obtained by… (More)

At zero-density, meson-nucleon vertex corrections to vacuum polarization are studied in the σ-ω model with the cutoff. It is shown that the properties of the vertex corrections to vacuum polarization… (More)

Silkworms (Bombyx mori) were reared on a carotenoid-deprived artificial diet, and the carotenoid-depleted eggs of the next generation were incubated so that we could observe the effect of the… (More)

We calculate the effective mass m∗ω of the ω-meson in nuclear medium by the σ-ω model with a vector field self-interaction (VFSI). We found that the direct and the indirect effects of the VFSI almost… (More)

In the past two decades, nuclei and nuclear matter have been studied in the framework of quantum hadrodynamics (QHD).[1, 2] The meson mean-field theory of nuclear matter[1] has produced successful… (More)
