 | Henderson, Thomas C. | Combining symbolic and numeric computation on the CRAY | It is now widely accepted that the CRAY supercomputers are very useful for large numeric applications, e.g., Finite Element Analysis, Fluid Dynamics, Image Processing, etc. Much work has been done to make them run efficiently on the CRAY. There has also been some effort to do symbolic computing (Al ... | CRAY supercomputers; Symbolic computation; Numeric computation | 1986 |

 | Ailion, David Charles | Commensurability and defect-induced phason gaps in incommensurate systems | The phason energy gap has been observed to increase on going from the incommensurate to higher-order commensurate phases in the "devil's staircase" compound [N(CH3)4]2ZnCl4. The gap was determined via the phason-induced 1 4N spin-lattice relaxation contribution, which was obtained from the variati... | Phasons; Commensurate; Incommensurate; Lattices; Modulation | 1985 |

 | Saam, Brian | Comment on pressure dependence of wall relaxation in polarized 3He gaseous cells | Zheng et al. [Zheng, Gao, Ye, and Zhang, Phys. Rev. A 83, 061401(R) (2011)] have measured a strong linear pressure dependence of the nuclear relaxation rate of 3He in glass cells typically used to generate and/or store polarized 3He at room and cryogenic temperatures. Their interpretation is that th... | | 2012-01-01 |
