Starting from a complete operator product expansion up to mass dimension-6 twist4 and up to first order in the coupling constants we investigate the splitting and mixing of ρ and ω mesons in isospin symmetric nuclear matter. Special attention is devoted to the impact of the scalar 4-quark condensates on both effects. In nuclear matter the Landau damping governs the ρ−ω mass splitting while the ...

A new class of spacetime defect solutions of Einstein Field equations of Edelen’s direct Poincaré Gauge Field theory without biaxial symmetry is presented. The interior solution describes a core of defects where curvature vanishes and Cartan torsion is nonvanishing. Outside the core (in vacuum) the solution represents a spacetime with vanishing curvature and torsion describing a nontrivial topo...

Both magnetic wire and acetate-based magnetic tape were used in the audio industry. Welsh and Lukoff [lj describe the early use of metal tape for digital magnetic recording. Acetate-based tape was used for digital recording by Raytheon at a relatively low tape velocity, as reported by Bloch [2]. At IBM it was decided to pursue an acetate-based plastic magnetic tape for computer input,‘ output b...

Fall COMDEX was the center of numerous showings of new tape technologies offering significant increases in tape capacity and performance. Of interest to users of midrange tape technology was the showing of Linear Tape Open (LTO) tape drives. Just as the upstart Linux operating system is nurturing a small but growing base of users, LTOcompliant products promise to secure a significant portion of...

We study the emergence and interaction of red tape and corruption in a principal–bureaucrat– agent hierarchy. The principal is to provide the agent with a unit of a good that involves externalities so that market mechanisms fail to achieve first best. Red tape produces information but is costly to the agent and is administered by a corrupt bureaucrat. First, the bureaucrat may extort bribes fro...

A multi-channel Optical Head has been developed to be incorporated with an Optical Tape Drive that enables greater than 1TB capacity and greater than 25 MB/s data transfer rate on a 0.5 mil thick, 0.5 inch wide optical tape that fits in a 3480 style cartridge. The optical design has been optimized to perform at 532 nm with maximum through put in the write path. With use of a 0.6 NA objective le...
