The chloroplasts of the leaves of Capsicum annuum cv. Purple Leaf Cherry are characterized by the presence of large electron translucent plastoglobules which comprise a considerable proportion of the plastid volume. The leaf chloroplasts of Purple Leaf Yellow cultivar contain, in addition, large starch granules which are frequently in intimate association… (More)

To optimize a connecting rod satisfying fatigue life, metamodel-based design optimization is proposed. To approximately predict both volume and fatigue life of connecting rod, kriging metamodel is constructed based on maximin eigenvalue sampling. Fatigue analysis is accomplished for the calculation of fatigue life. The results of metamodel-based design… (More)

A distinct isotopic effect in φ photoproduction at √ s ∼ 2− 5 GeV region is identified by examining the production amplitudes due to Pomeron-exchange and meson-exchange mechanisms. This effect is mainly caused by the π-η interference constrained by SU(3) symmetry and the isotopic structure of the γNN coupling in the direct φ-radiation amplitude. It can be… (More)

The electromagnetic production of associated strangeness on the proton in the total center-of-mass range from threshold up to W ≈ 2.3 GeV is under extensive study both experimentally and theoretically. Besides understanding the elementary reaction mechanism, a strong motivation is the search for the missing baryon resonances and improved insights into the… (More)

The total cross section for the near threshold η production in proton-proton collisions has been investigated with the assumption that the production mechanism is due to the emission of a meson x(π, η, σ) from one of the nucleons followed by a xN → ηN transition on the second one. The xN → ηN amplitudes are generated from the unitary multi-channel… (More)

Neutron structure functions can be extracted from proton and deuteron data and a representation of the deuteron structure. This procedure does not require DIS approximations or quark structure assumptions. We find that the results depend critically on properly accounting for the Q dependence of proton and deuteron data. We interpolate the data to fixed Q,… (More)

To facilitate the relativistic heavy-ion calculations based on transport equations, the binary collisions involving a ∆ resonance in either the entrance channel or the exit channel are investigated within a Hamiltonian formulation of πNN interactions. An averaging procedure is developed to define a quasi-particle ∆ and to express the experimentally measured… (More)

An effective Hamiltonian consisting of bare ∆ ↔ πN , γN vertex interactions and energy-independent meson-exchange πN ↔ πN, γN transition operators is derived by applying a unitary transformation to a model Lagrangian with N,∆, π, ρ, ω, and γ fields. With appropraite phenomenological form factors and coupling constants for ρ and ∆, the model can give a good… (More)

We present organization and solutions for a new analysis of all πN elastic and the major inelastic channels to extract detailed characteristics of the contributing baryon resonances. This work is based on the work of R. Cutkosky and collaborators at CMU about 20 years ago. The model features analyticity at the amplitude level and unitarity. Results are… (More)

We show that the neutron and proton transition densities predicted by recent QuantumMonte Carlo calculations for A = 6, 7 nuclei are consistent with pion scattering from 6Li and 7Li at energies near the ∆ resonance. This has provided a microscopic understanding of the enhancement factors for quadrupole excitations, which were needed to describe pion… (More)
