... [41]. The use of thrombin significantly increases the cost of the purification, and the require- ment for HPLC increases the length and complexity of the purification procedure. Moreover, as with the studies ... (Fig. 1). The requirement for a start codon adds a methionine residue at the N-terminus; hence, the peptides expressed here are referred to as Ab(M1–40) and Ab(...

... vector is given on the left, and the right on the right, that is to say, the fir s t letter in the bigram is on the left and the second on the right. The first two singular vector pairs are dominated ... accurate as the direction of the singular vectors settles. These appr ox- imations will therefore not interfere with the accuracy of the final result, though they mig...

We use the entropy of the posterior distribution as the confidence ... the En- glish phrase can be aligned correctly. On the other hand, high entropy implies ambiguity presented in discriminating the correct foreign phrase from the oth...
