A classical description of pairing as vibrations and rotations in the number of particles as a function of the gauge angle is outlined and applied to a calculation of the pair transfer by the pair field in a collision between two superfluid nuclei. I . Surface Vibrations and Rotations The motivation for taking up the subject of a macroscopic description of pairing is the success of the macrosco...

The structure and properties of absorbed fluorine and chlorine atoms on GaAs surfaces are investigated. The energies of surface species' localized vibrations are determined. Our results show that localized As±Cl and Ga±Cl valence vibrations occur in the 40 and 50 meV regimes, respectively, while As±F and Ga±F vibrations are found in the 90 and 80 meV regimes, respectively. Comparisons are made ...

In humans, the tactile perception of fine textures (spatial scale <200 micrometers) is mediated by skin vibrations generated as the finger scans the surface. To establish the relationship between texture characteristics and subcutaneous vibrations, a biomimetic tactile sensor has been designed whose dimensions match those of the fingertip. When the sensor surface is patterned with parallel ridg...

We present a method to compute harmonic vibrations that uses the structures and the forces in the structures that are obtained from a geometry optimization. It does not require any additional electronic structure calculations. The method generally takes only on the order of minutes on a regular PC, but it does not guarantee the calculation of all vibrations of a system. Tests on small adsorbate...

BACKGROUND For generations many families in and around Florida's Apalachicola National Forest have supported themselves by collecting the large endemic earthworms (Diplocardia mississippiensis). This is accomplished by vibrating a wooden stake driven into the soil, a practice called "worm grunting". In response to the vibrations, worms emerge to the surface where thousands can be gathered in a ...

The structure of a surface grinder comprises of a base, all the other machine members like column, the reciprocating table, the grinding wheel, spindle and spindle motor are all supported on the base. In the design of one such surface grinder waviness was observed on the ground surface. It has become necessary to investigate into the behavior of the machine under working conditions. Investigati...
