Mao's Melons

Spontaneous Tetraploid Melons

Since 1968, three spontaneous 4x melons (Cucumis melo L.) plants were discovered in our field or greenhouse plantings. Two were found in the cultivar Planters Jumbo and one in the virescent marker C879-52. Each of these 4x plants had rounded cotyledons, shorter internodes, thicker stems and leaves, more hairs, and smaller fruits, with larger stem and blossom scars, than their 2x counterparts. A...

Computing Vertex-Disjoint Paths using MAOs

Let G be a graph with minimum degree δ. It is well-known that maximal adjacency orderings (MAOs) compute a vertex set S such that every pair of S is connected by at least δ internally vertex-disjoint paths in G. We present an algorithm that, given any pair of S, computes these δ paths in linear time O(n+m). This improves the previously best solutions for these special vertex pairs, which were f...

Screening Melons for Adaptability in North Carolina

INTRODUCTION Cantaloupe or muskmelon (Cucumis melo var. cantaloupensis, Cucurbitaceae) production is an important industry for North Carolina. In 2000, North Carolina produced 729 ha (1,800 acres) of cantaloupes valued at $20 million. Besides cantaloupe, there is a tremendous diversity of melons in the Cucumis melo species, each having unique flavors, texture, and appearance. Because of low pro...

Maos non-volatile memory structures with lower bandgap storage layer

2014 Introduction of a thin Si3N4 layer in metal-Al2O3-SiO2-Si (MAOS) memory structures leads to increased charge storage capability and reduced writing voltages for these MANOS structures. O2 annealing significantly affects these properties and the charging mechanism. Preliminary results on charge retention are presented. REVUE DE PHYSIQUE APPLIQUÉE TOME 13, DÉCEMBRE 1978,
