Mallon, Ronald | 'Race': normative, not metaphysical or semantic | In recent years, there has been a flurry of work on the metaphysics of race. While it is now widely accepted that races do not share robust, biobehavioral essences, opinions differ over what, if anything, race is. Recent work has been divided between three apparently quite different answers. A varie... | | 2006 |

Liu, Feng | (BAl12)Cs: a cluster-assembled solid | First-principles calculations on the geometry and stability of AlnBm clusters have been carried out to examine the effect of size, composition, and electronic-shell filling on their relative stability. It is shown that although Al and B are both trivalent, a BAl12 cluster is more stable than an Al1... | First-principles calculations; (BAl12)Cs; Cluster-assembled; AlnBm clusters | 1997-06 |

Furse, Cynthia M. | 13 crazy, notorious things to do in an EM class | The average attention span of an adult human is 12-20 minutes. Our lectures are 50-80 minutes. Attention Span Math reminds us to take a break now and then, and to bring the class back to life by bringing some life to the class. Many students learn things better if they can see and touch them, so thi... | Attention span; Fun | 2005-06 |

Ailion, David Charles | 14N study of the role of N-D---O bonds in the deuteron glass transition | 14N spin-lattice relaxation-time measurements in Rb0.28(ND4)0.72D2PO4 provide direct evidence for the fast exchange averaging of the "long" and "short" N-D---O hydrogen bonds between the ND4 group and the four surrounding PO4 groups. This exchange and the associated distortion of the ND4 tetrahedron... | NMR; Hydrogen bonds; Spin-lattice; Relaxation-time; Deuteron glass | 1999 |
