Point island models (PIMs) are presented for the formation of supported nanoclusters (or islands) during deposition on flat crystalline substrates at lower submonolayer coverages. These models treat islands as occupying a single adsorption site, although carrying a label to track their size (i.e., they suppress island structure). However, they are particularly effective in describing the island...

This paper is divided into two parts: classic knowledge on theory of island biogeography (I) and the evolution of behaviour and morphology under insular constraints (II). The main subjects dealt with are: the problem of small populations (1); the biological definition of an island and the importance of biological studies on islands (2); the species-area effect and its consequences for a nature ...

Thin ®lms are often grown away from thermodynamic equilibrium and their morphology becomes determined by kinetics. The ®nal structure of the epitaxial ®lm is decided in the very early stage of submonolayer nucleation and island growth. Recent experiments with scanning tunneling microscopy opened up an unprecedented view of this early stage of epitaxial growth. Variable sample temperatures enabl...

We have experimentally demonstrated pumping of Cooper pairs in a single-island mesoscopic structure. The island was connected to leads through SQUID (Superconducting Quantum Interference Device) loops. Synchronized flux and voltage signals were applied whereby the Josephson energies of the SQUIDs and the gate charge were tuned adiabatically. From the current-voltage characteristics one can see ...

We used four variable microsatellite loci to examine the distribution of genetic variation and degree of genetic structuring among three subcolonies of Waved Albatrosses (Phoebastria irrorata). The breeding population of this species is almost entirely limited to the island of Española in the Galápagos Archipelago. Such strong philopatry could lead to population genetic structure among subcolon...

the study area is located about 3 km southwest of the hormoz island in the hormozgan province, in the persian gulf. the main rock units in the region consist of a highly altered acidic pluton cratophyre, which is responsible for apatite formation, diabasic dike, marl and altered basalt. apatite is the only phosphate mineral in the hormoz island, which has accumulated ree in its crystal structur...

Lee (1993) reported some island effects in long-distance scrambling in Korean. Based on adequacy of scrambling, she argued that a relative or an adjunct clause, which is not selected by a verb via selection (Cinque 1990), forms a strong island, whereas a whcomplement or a propositional complement clause forms a weak island or doesn’t show any island effect as they can be selected by a verb. Lee...

Narrative-centered learning environments hold much promise for education and training. Much of the appeal of narrative-centered learning lies in the belief that narrative context provides a meaningful structure integrating pedagogical objectives into a unifying, coherent form that serves as a powerful motivating force for students. This paper explores the relationship between narrative-centered...

The Larsemann Hills range is an ice-free oasis on the Ingrid Christensen Coast of Princess Elizabeth Land, East Antarctica, which includes Bharti Island, Fisher Island, McLeod Island, Broknes Peninsula, Stornes Peninsula, and several other islands, promontories, and nunataks. The Larsemann Hills is an ice-free area of approximately 50 km2, located halfway between the Vestfold Hills a...
