We present data-analysis schemes and results of observations with the TAMA300 gravitational-wave detector, targeting burst signals from stellar-core collapse events. In analyses for burst grav-itational waves, the detection and fake-reduction schemes are different from well-investigated ones for a chirp-wave analysis, because precise waveform templates are(More)
and of six signals in the I3C-NMR spectrum (Table 1) is consistent with a molecular structure with DZh symmetry and delocalized n-electron system. This is confirmed by the X-ray structure analysis,"" which reveals a planar ring system with inversion center for 10 (Fig. 1). The maximum distance of the ring-C atoms from the mean plane is k 1.5 pm. The(More)
It has been recently shown that the lens equation for a binary gravitational lens, which is apparently a coupled system, can be reduced to a real fifth-order (quintic) algebraic equation. Some algebraic properties of the real quintic equation are revealed. We find that the number of images on each side of the separation axis is independent of the mass ratio(More)
