The Number of Human Genes and Proteins

Davison D., Bristol-Myers Squibb, Pharmaceutical Research Institute, US

The definitive prototype for nanotechnology is the cell. Its many machines and exquisitely controlled internal and external movements are a reference for all researchers working in the field. The complete instructions for every molecular machine [...]

Complex Fluid Dynamics in BioMEMS Devices

Liepmann D., University of California-Berkeley, US

MEMS technologies promises to revolutionize health care by providing precise control of biological fluids for both diagnoses and treatments. For example, microneedles can be used for sample collection for biological analysis, delivery of cell or [...]

Modeling and Simulation for MEMS Design, Industrial Requirements

Neul R., Robert Bosch GmbH, DE

The development process of today’s products is dominated by demands like ‘product performance’, ‘quality, ‘time to market’, ‘development cost’, ‘development risk’ etc., while the products’ complexity is increasing. Design methods for MEMS devices are discussed, [...]

The Vision and Action Plan of the National Nanotechnology Initiative

Roco M., National Science Foundation, US

The vision of novel phenomena, unity in nature, and promise of the most efficient manufacturing length scale has been essential in establishing the multidisciplinary National Nanotechnology Initiative (NNI). The research opportunities and projections of their [...]

Latency Minimization for Permutations Using Distributed Technology

McAven L.F., Schlesinger M., Kent R.D., University of Windsor, CA

Distributed processing is a new concept considered as a solution to the cost problem relating to scaling parallel machines. Any problem given to a distributed system of n-processors can be better solved by a single [...]

Hopping and Correlation Effects in Atomic Clusters and Networks

Kulik I.O., Bilkent University, TR

Exact solution for hopping and correlation effects in atomic clusters and mesoscopic/nanoscopic networks is outlined. The program translates the Hamiltonian operator of the cluster written in terms of second-quantized creation and annihilation operators, to sparse [...]

The Distributive Calculation of Unitary Group Recoupling Coefficients

McAven L.F., Schlesinger M., Kent R.D., University of Windsor, CA

Symmetries, through group theory, can provide exact information about complex systems. However approximations are often made, for example density functionals are used in quantum chemistry, because it is impractical to obtain group coefficients. Coefficients for [...]

Virtual Nanofabrication of Electronic Materials

Pozhar L.A., University of Surrey, UK

A rigorous statistical mechanical theory of inhomogeneous fluids and molecular dynamics simulations are used to predict characteristic features of transport processes and the corresponding transport coefficients for a number of model nanoscale systems in terms [...]

Continuum Solvation Model for ab initio Molecular Dynamics Simulations

Fattebert J-L., Gygi F., Lawrence Livermore National Laboratory, US

In electronic structure calculations, a polarizable solvent can be represented as a continuous homogeneous dielectric. In most models, the value of the dielectric presents a discontinuity at the solute-solvent interface. For first principles pseudopotential DFT [...]

Managing the Distribution of Recursively Calculating Matrix Elements

McAven L.F., Schlesinger M., Kent R.D., University of Windsor, CA

Interaction stregths and material properties are represented mathematically by matrix elements. The calculation of matrix elements is therefore critical in the interpretation and modelling of physical systems. Part of the matrix elements can be factored [...]
