  • Using the polyclonal antibody for Xanthomonas citri ampicillin acylase raised in Pseudomonas-free Balb/c mice, the immunochemical similarity of several types of penicillin acylases including Erwinia aroideae penicillin V acylase, Escherichia coli penicillin G acylase, Pseudomonas melanogenum and Acetobacter turbidans ampicillin acylases, and Pseudomonas cephalosporin acylase was examined. Among tested, only P. melanogenum ampicillin acylase showed the cross-reactivity with the antibody.

  • In this paper, we extend the work by Lee et al. (2010) to multidimensional di usion processes. A test statistic analogous to the one-dimensional case is proposed to inves-tigate the joint stability of covariance matrix parameters and, under certain regularity conditions, is shown to have a limiting distribution of the sup of a multidimensional Brownian bridge. A simulation result is provided for illustration.
