Many species survive in specialized habitats. When these habitats are destroyed or fragmented the threat of extinction looms. In this paper, we use percolation theory to conside...
We develop a general formalism for calculating the large-order behavior of perturbation theory for quantized systems of unequal-mass coupled anharmonic oscillators. Our techniqu...
We consider, from a number of different viewpoints, the tensor coefficients which describe second harmonic generation, optical rectification, and the Pockels or linear electro-o...
Global changes have the potential to cause a mass extinction. Predicting how species will respond to anticipated changes is a necessary prerequisite to effectively conserving th...
A gradient index (GRIN) lens using a negative index of refraction material (NIM) has been designed and tested. The GRIN lens was fabricated using a NIM slab with a variable inde...
In recent years, label-free biosensors not requiring external modifications have been receiving intense attention. A label-free optical biosensor, which retains many of the desi...
The design and testing of a micromotor capable of moving multiple objects in three dimensions is discussed. The fixed surface of the motor, fabricated on a silicon wafer, contai...
Astrometric surveys provide the opportunity to measure the absolute\nmagnitudes of large numbers of stars, but only if the individual line-of-sight\nextinctions are known. Unfor...
AbstractWe propose that the feedforward connection from the lower visual cortical area to the higher visual cortical area provides an approximated inverse model of the imaging p...
A general set of states on a lattice in the phase plane is considered. The discrete set of von Neumann coherent states for a harmonic oscillator is a particular case of the abov...
We continue examination of the photon correlation properties of silicon avalanche photodiodes operated in photon-counting mode by extending their operation from that of passive ...
