Exploring Tuning Strategies for Quantum Chemistry Computations

Effective execution of applications using a parallel computing environment that share resources such as network bandwidth, I/O and main memory require that some sort of adaptive mechanism be put in place which enables efficient usage of these resources. The adaptation adjusts the most computationally intensive part of the application thus leading to an efficient execution. General Atomic and Mo...

Percolation with bubbles and toroids

Multifragment disintegration of finite systems with toroidal and bubble-shaped configurations is studied within the framework of a bond-percolation model. Calculations for these finite systems predict enhanced fragment production for less compact decay configurations. Power law fits to the predicted mass distributions reveal a strong sensitivity of the extracted critical exponents on the geomet...

DNA toroids: stages in condensation.

The effects of polylysine (PLL) and PLL-asialoorosomucoid (AsOR) on DNA condensation have been analyzed by AFM. Different types of condensed DNA structures were observed, which show a sequence of conformational changes as circular plasmid DNA molecules condense progressively. The structures range from circular molecules with the length of the plasmid DNA to small toroids and short rods with app...

Tuning cell autophagy by diversifying carbon nanotube surface chemistry.

The induction of autophagy by nanoparticles causes nanotoxicity, but appropriate modulation of autophagy by nanoparticles may have therapeutic potential. Multiwalled carbon nanotubes (MWCNTs) interact with cell membranes and membrane-associated molecules before and after internalization. These interactions alter cellular signaling and impact major cell functions such as cell cycle, apoptosis, a...

Tuning the growth orientation of epitaxial films by interface chemistry.

The support of epitaxial films frequently determines their crystallographic orientation, which is of crucial importance for their properties. We report a novel way to alter the film orientation without changing the substrate. We show for the growth of CoO on the Ir(100) surface that, while the oxide grows in (111) orientation on the bare substrate, the orientation switches to (100) by introduci...
