In order to expand the applicability of modified embedded atom methods (MEAMs) from bulk to non-bulk systems, a dimer reference MEAM (DR-MEAM) is proposed. In this method, a diatomic structure is selected as the reference structure and the parameters for Cu are determined from the properties of the equilibrium bulk structure and some clusters, in order to obtain a wide range applicability from the bulk to the non-bulk systems. In the determination of the parameters, the lattice constant, the binding energy, and the bulk modulus are used as the bulk properties and the binding energy, the bond length, and the bond angle of Cu, (n 2, 3, 4) are used as the clusters properties. Several other properties of Cu are calculated by the DR-MEAM and the parameters, and they are compared with experimental results and DFT results to examine the present method and parameters. It is found that they exhibit good agreements for many properties such as the lattice stability, the shear elastic constants, the vacancy formation energy, the surface energy of low index crystal surfaces, the binding energy of the Cu clusters (n >= 5), etc. It is suggested that the present method and parameters have a wider range of applicability than the conventional MEAMs. The DR-MEAM does not exhibit good agreement only for the bond angle of Cu(3) and Cu(4) This disagreement seems to suggest a theoretical limitation of the embedded atom method approximation.

Al-Zayyan Temple or Qasr Al-Zayyan might be regarded as one in a chain of several fortresses that the Romans built to secure the salver's trade caravan route between Asyut and Sudan, known as Darb Al-Arbain. Al-Zayyan temple lies about 25 km south of Al-Kharga city, the capital of the New Valley, and deviates to the east of Al-Kharga-Paris main road some 2 km along the Al-Zayyan-Aarif minor road. The background information about the temple is very scarce, and even what is known is neither clear nor accurate. Some indications have ascribed it to Amenebis and that it was restored during the reign of Emperor Antoninus (AD 138-161). An integrated ground-penetrating radar (GPR)survey using the SIR 2000 Geophysical Survey Systems, Inc. (GSSI) together with magnetic survey using FM36 (GeoScan) and the three component fluxgate gradiometer TRM-70D (Tokin) have been applied to the western side of the temple. The results show relatively large-scale buried structures in a direction intersecting that of the present temple at about 45°. Some particular features within the structure have been speculatively ascribed on the basis of comprehending their signatures in the GPR sections. The magnetic results have improved the identification of some objects revealed by the GPR and provided ideas about some of the other features. © 2002 John Wiley and Sons, Ltd.
