SYNOPSIS. The ability of scleractinian corals to survive changes that are predicted in the global environment over the next century will lie in their physiological mechanisms of acclimatization. Corals display rapid modifications in behavior, morpholo . . .

Cell surface sugar chains extend away from the cell membrane and offer a first line of contact with approaching cells and substrates. These sugars are candidates for mediating cell-cell adhesion and migration. Here, I review experiments that implicate . . .

Tumor and embryonic cell surfaces are examined in this symposium with respect to their roles in cell-cell interactions and in early development and malignancy. Three sets of studies have been recently performed in my laboratory to help elucidate the n . . .

This review discusses three questions pertaining to gamete release by fucoid algae at low tide: 1) Are gametes viable and does fertilization occur at low tide?, 2) How many gametes are released at low tide versus at high tide? and 3) Is gamete release . . .

The interfacial electronic structure and dynamics of poly(3-hexylthiophene)/fullerene (C60 and [6,6]-phenyl-C61-butyric acid methyl ester) heterojunctions are studied by ab initio nonadiabatic molecular dynamics. These junctions render ultrafast elect . . .

Using an ab initio-based parametric dislocation dynamics approach we show that Shockley partials on successive glide planes greatly assist the widening of stacking faults (SFs) in Al and Ag. This effect is amplified when all trailing partials are pinn . . .

Male-male competition in plants is thought to exert selection on flower morphology and on the temporal presentation of pollen. Theory suggests that a plant's pollen dosing strategy should evolve to match the abundance and pollen transfer efficiency of . . .

We explore an electrostatic mechanism for tuning the nonlinearity of nanomechanical resonators and increasing their dynamic range for sensor applications. We also demonstrate tuning the resonant frequency of resonators both upward and downward. A theo . . .
