Though more diicult to program, distributed-memory parallel machines provide greater scalability than their shared-memory counterparts. Distributed Shared Memory (DSM) systems provide the abstraction of shared memory on a distributed machine. While DSMs provide an attractive programming model, they currently can not eeciently support all classes of scientiic applications. One such class are tho...

Research investigating row spacing in high-yielding, high-input cotton (Gossypium hirsutum L.) production systems has found higher lint yields but no maturity benefits using high plant density, 25 cm spaced ultra-narrow rows (UNR). Seven experiments comparing 38 UNR and conventionally (100 cm) were conducted over three years to determine if changes density or management could optimize yield a s...

Leucaena (Leucaena leucocephala (Lam.) de Wit) has proven to be a very productive tropical legume, but the factors which control production under intensive management have not been well defined. Thus three harvest frequencies (based on attained plant height), three population densities, and two plant types of leucaena were evaluated at North Kohala, Hawaii (120-m elevation, Typic Ustropept). Pl...

Modification of peptide sequence offers versatile control over their self-organization capability within adlayers adsorbed on surfaces. However, to gain full the self-organization, clear links between and lateral ordering in these must be established. Using molecular dynamics simulations WA or AW dipeptides, spontaneous emergence ordered nano-patterns containing neutral, zwitterion, neutral-zwi...
