Characterization of SDP Designs That Yield Certain Spin Models
[article]
2002
arXiv
pre-print
Preserved Fulltext
We characterize the SDP designs that give rise to four-weight spin models with two values. We prove that the only such designs are the symplectic SDP designs. ...
The proof involves analysis of cardinalities of intersections of four blocks. ...
Guo and Huang [8] considered certain types of four-weight spin models, which they called "four-weight spin models with exactly two values on W 2 " (we will explain this further in section 2). ...

The parameters that characterize the intricate water diffusion in tumors may also reveal their distinct pathology. ...
The present in vitro study aimed to discover connections between the NMR biexponential diffusion parameters [fast diffusion phase (D FDP ), slow diffusion phase (D SDP ), and spin population of fast diffusion ...
These characteristics imply that intracellular water diffusion cannot be characterized by a single ADC. ...
