Precision calculation for e+ e- -> 2f: the KK MC project

We present the current status of the coherent exclusive (CEEX) realization of the YFS theory for the processes in e+ e- -> 2f via the KK MC. We give a brief summary of the CEEX theory in comparison to the older (EEX) exclusive exponentiation theory and illustrate recent theoretical results relevant to the LEP2 and LC physics programs.Comment: 5 pages, 4 figures, 2 diagrams - presented by BFLW at RADCOR0

Magnetostrictive Emat Efficiency as a Materials Characterization Tool

Electromagnetic acoustic transducers (EMATs) are ideal for on-line inspection of hot metal sheets, because they provide a noncontacting means for generating and detecting ultrasound in metals. EMATs are especially attractive for probing steels and magnetic alloys, because their transduction efficiency is larger than in nonferromagnetic materials. The source of the enhanced efficiency is magnetostriction, the change of length of a ferromagnetic material that accompanies magnetization.</p
