We have observed transverse pattern formation leading to highly regular structures in both the near and far fields when a near-resonant laser beam propagates without feedback through an atomic sodium vapor. One example is a regular far-field honeycomb pattern, which results from the transformation of the laser beam within the vapor into a stable three-lobed structure with a uniform phase distri...

The Internet can be a powerful cross-cultural incoming tourism communication tool if used in a proper way. Visitor images of destinations are important drivers of consumer choice and therefore, how destinations provide information to visitors is critically important to image formation. This text first looks at the general features of Internet as a cross-culture communication tool in tourism, ba...

Pattern formation in development is a complex process which involves spatially distributed signals called morphogens that influence gene expression and thus the phenotypic identity of cells. Usually different cell types are spatially segregated, and the boundary between them may be determined by a threshold value of some state variable. The question arises as to how sensitive the location of su...

This paper focuses on the application of intuitive game interfaces (including brain machine interfaces) to serious gaming, in particular real-time, interactive, and highly realistic environments for advanced concept development, experimentation and training.
