We describe and apply a point model of the joint evolution of tidal landforms and biota which incorporates the dynamics of intertidal vegetation; benthic microbial assemblages; erosional, depositional, and sediment exchange processes; wind-wave dynamics, a ...
The photoelectron properties of DNA and RNA bases are studied using many-body perturbation theory within the GW approximation, together with a recently developed Lanczos-chain approach. Calculated vertical ionization potentials, electron affinities, and to ...
Widespread empirical evidence suggests that extraterrestrial forcing influences the Earth's climate, but how this could occur remains unclear. Here we describe a new approach to this problem that unifies orbital, solar and lunar forcing based on their comm ...
Numerical investigations covering all the physical processes occurring in the surf and swash zones, including the cross-shore and longshore flows, have not been fully developed, although considerable work in 2D has appeared in recent years. However, given ...
A part of the beam losses at transition crossing of high intensity beams in the CERN PS have been attributed to an excursion of the closed orbit. The orbit jump occurs simultaneously with the jump of the transition energy triggered by pulsed quadrupoles. I ...
Wave and tide are important forcing factors that typically co-exist in coastal environments. A numerical study was conducted to investigate individual and combined effects of these forces on flow and mixing processes in a near-shore subterranean estuary. A ...
A numerical study was conducted to investigate the influence of tides on the fate of terrestrially-derived BTEX discharging through an unconfined aquifer to coastal waters. Previous studies have revealed that tide-induced seawater circulations create an ac ...
We are examining techniques for manipulation of microfabricated elements using arrays of bacteria as microactuators. Flagellated Serratia marcescens bacteria are attached to microstructures using a blotting technique that creates a bacterial monolayer carp ...
Groundwater flow and chemical transport in subterranean estuaries are poorly understood despite their potentially important implications for chemical fluxes from aquifers to coastal waters. Here, a numerical study of the dynamics in a subterranean estuary ...
We present a model of charge transport in organic molecular semiconductors based on the effects of lattice fluctuations on the quantum coherence of the electronic state of the charge carrier. Thermal intermolecular phonons and librations tend to localize p ...
