Two important tasks that the visual system has to perform are determining the direction of motion and the spatial location of objects. It has recently been shown that the perceived location of an object moving in the frontal-plane is displaced along the direction of motion (e.g. Nature 397 (1999) 610; Vision Research 31 (1991) 1619). The aim of the present study is to examine the extent of this...

The issue raised in this Letter is classical, not only in the sense of being nonquantum, but also in the sense of being quite ancient: which subset of 4x4 real matrices should be accepted as physical Mueller matrices in polarization optics? Nonquantum entanglement or inseparability between the polarization and spatial degrees of freedom of an electromagnetic beam whose polarization is not homog...

eccrine gland metabolism. It is well known that lactate concentration increases during physical exercise, being a useful parameter to monitor wellness, physical fitness and the effects of exercise . Detection in sweat offers a less invasive, and dynamic way of measuring lactate concentration, particularly during exercise. Current methods of detection of lactate include fibre optics, conducting ...

Aradhana Narula-Tam MIT Lincoln Laboratory, 244 Wood Street, Lexington, MA 02420 [email protected] Eytan Modiano MIT Laboratory for Information and Decision Systems, Cambridge, MA 02139 [email protected] Abstract: With WDM, a single physical link failure may correspond to multiple logical link failures. We consider the design of physical topologies that ensure logical rings can be embedded in a sur...

The study of the propagation of light is a fascinating fields of research that is interesting in itself because it gives rise to beautiful and complex mathematical structures. Furthermore, understanding the propagation of light is crucial in applications such as lasers and optical fibers. In this proposal I will focus on a model that has been proven to be quite successful in describing the prop...
