Communication with Chaotic Lasers
Recent experiments with chaotic electronic circuits have shown the possibility of communication with chaos. The experimental demonstration of chaotic communication with an optic...
Theory and applications of optical remote sensing
Field measurements of bidirectional reflectance soil reflectance soil influences in remotely sensed vegetation-canopy spectra the theory of photon transport in leaf canopies est...
Separation of a mixture of independent signals using time delayed correlations
The problem of separating n linearly superimposed uncorrelated signals and determining their mixing coefficients is reduced to an eigenvalue problem which involves the simultane...
Single-target molecule detection with nonbleaching multicolor optical immunolabels
We introduce and demonstrate the use of colloidal silver plasmon-resonant particles (PRPs) as optical reporters in typical biological assays. PRPs are ultrabright, nanosized opt...
Short-Term Memory in Vision
Experiments are performed that demonstrate some of the functional properties of short-term storage in the visual system, its decay, readout and erasure. Results indicate that th...
Magnetic, transport, and optical properties of monolayer copper oxides
The authors review the results of a wide variety of experiments on materials such as ${\mathrm{La}}_{2}{\mathrm{CuO}}_{4}$ and ${\mathrm{Nd}}_{2}{\mathrm{CuO}}_{4}$ that contain...
Determination of the concentration of surface hydroxyl groups on metal oxide films by a quantitative XPS method
Quantitative XPS has been used to determine the surface concentration of hydroxyl groups in native air-formed oxide films on metals having low surface areas. A mathematical expr...
