Generating small-scale structures from large-scale ones via optical near-field interactions

Optical magnetic near-field intensities around nanometer-scale surface structures

Recently, local probes used in optical experiments added a new dimension to the study of the optical properties of small particles lying on a surface. Until now, several theoretical frameworks, developed to understand the interaction of optical fields with mesoscopic and nanoscopic objects, emphasized mainly the prediction of the electric near-field distributions generated by these structures. ...

From large-scale to small-scale dynamos

Several recent advances in turbulent dynamo theory are reviewed. High resolution simulations of small-scale and large-scale dynamo action in periodic domains are compared with each other and contrasted with similar results at low magnetic Prandtl numbers. It is argued that all the different cases show similarities at intermediate length scales. On the other hand, in the presence of helicity of ...

Sorption coefficients for interactions between volatile organic compounds and indoor surface materials from small-scale, large-scale, and field tests

Adsorption and desorption by indoor surface materials can have significant impacts on the level of volatile organic compounds (VOCs) indoors. Models for the sink effects consist of two coefficients: sorption (ka) and desorption (kd). Two coefficients were determined from 7 VOCs and 15 combinations of materials using small-scale chamber tests. Additionally, these coefficients were evaluated with...

Generating Complex Connectivity Structures for Large-Scale Neural Models

Biological neural systems and the majority of other realworld networks have topologies significant different from fully or randomly connected structures, which are frequently applied for the definition of artificial neural networks (ANN). In this work we introduce a deterministic process generating strongly connected directed graphs of fractal dimension having connectivity structures very disti...
