An invariance of the spectrum of a full configuration interaction (CI) matrix with respect to unitary transformations of the orbital basis set is frequently used as a test of the correctness of CI programs. In this paper we argue that using instead the invariance properties of the first two moments

## Abstract The atmosphere and land surface can alter the structure of a landfalling tropical cyclone (TC), resulting in complex spatial patterns of rainfall. Rather than average observations from many TCs, this study utilizes a Geographic Information System (GIS) to spatially analyse radar reflect
Poly(ether ester)s consisting of poly(ethylene oxide) and poly(ethylene terephthalate) segments, EOET copolymers, could be used as shape memory polymers (SMP). Crystalline structural characters of the copolymers during the memory process were investigated by dynamic mechanical analysis, differential
## Abstract The magnetic field correlation (MFC) at an applied field level of 3 Tesla was estimated by means of MRI in several brain regions for 21 healthy human adults and 1 subject with aceruloplasminemia. For healthy subjects, highly elevated MFC values compared with surrounding tissues were fou
