You would not have expected the Editor-in-Chief of this journal to remain silent at that moment and I certainly was not. However, what the statement did highlight, of c...

Realization of u-Contents: u-Realism, u-Mobility and u-Intelligence

—Recently the developments of Ubiquitous Computing and Augmented Reality technologies have made many changes on the existing applications. However, the contents used in the applications have been not revised conceptually. Thus, an expansive representation of the contents is required to adapt resources to new computing environments, and to reflect new emerging features such as realism, mobility ...

Lecture 4: U-Statistics & U-Process Minimizers

Hoeffding (1948a) developed the basic theory of U-Statistics, a family of estimates which includes many familiar and interesting examples. This lecture reviews this theory. Standard references for the material presented here include Serfling (1980, Chapter 5), Lehmman (1999, Chapter 6) and van der Vaart (1998, Chapters 11 & 12). The basic theory of U-Statistics allows for a presentation of larg...

A technique is described for the simultaneous and controlled random mutation of all three heavy or light chain complementaritj-determining regions (CDRs) in a single-chain Fv specific for the 0 polysaccharide of SalmoneUla serogroup B. Sense oligonucleotides were synthesized such that the central bases encoding a CDR were randomized by equimolar spiking with A, G, C, and T at a level of 10%/1 w...
