Conductivity of disordered graphene at half filling
, 2007 We study electron transport properties of a monoatomic graphite layer (graphene) with different types of disorder at half filling. We show that the transport properties of the system depend strongly on the symmetry of disorder.

Mailed thermoluminescent dosimeter determination of entrance skin exposure and half-value layer in mammography [PDF]
American Journal of Roentgenology, 1978 A method of providing in vivo measurement of entrance skin exposure for mammography using mailed thermoluminescent dosimeters has been developed. The dosimeters are calibrated to 137Cs (662 keV), and a correction is applied to account for energy response.
