"Microbiology Topics" discusses various topics in microbiology of practical use in validation and com­ pliance. We intend this column to be a useful resource for daily work applications. Reader comments, questions, and suggestions are needed to help us fulfill our objective for this col­ umn. Please send your comments and suggestions to column coordinator Scott Sutton at scott.sutton@ microbiol...

We calculate (g − 2) of the muon and the QED coupling α(M 2 Z), by improving the determination of the hadronic vacuum polarization contributions and their uncertainties. We include the recently re-analysed CMD-2 data on e + e − → π + π −. We carefully combine a wide variety of data for the e + e − production of hadrons, and obtain the optimum form of R(s) ≡ σ 0 had (s)/σ pt (s), together with i...

Current e-Learning is based on learning management systems that provide certain standard services course authoring and delivery, tutoring, administration and collaboration facilities. Rapid development of mobile technologies opens a new area of m-Learning to enhance the current educational opportunities. Field trips are a relevant part of the curriculum, but for various reasons it is often diff...

We characterize the class of uniform domains in terms of capacity. As a byproduct of this investigation we provide results describing when a Loewner domain will be QED.

Recently, we have developed a unified approach to QED in arbitrary linearly responding media in equilibrium—media that give rise to absorption [Phys. Rev. A 75, (2007) 053813]. In the present paper we show that, under appropriate conditions, the theory can be quite naturally generalized to amplifying media the effect of which is described within the framework of linear response theory. We discu...
