Phase Probability Distribution

Cryo-electron microscopy has been developed to the point where one can image thin protein crystals to 3.5 Å resolution. In our study of the crotoxin complex crystal, we can confirm this structural resolution from optical diffractograms of the low dose images. To retrieve high resolution phases from images, we have to include as many unit cells as possible in order to detect the weak signals in the Fourier transforms of the image. Hayward and Stroud proposed to superimpose multiple image areas by combining phase probability distribution functions for each reflection. The reliability of their phase determination was evaluated in terms of a crystallographic “figure of merit”. Grant and co-workers used a different procedure to enhance the signals from multiple image areas by vector summation of the complex structure factors in reciprocal space.

Security Issues

Now a day’s mobile communication has become a serious business tool for the users. Mobile devices are mainly used for the applications like banking, e-commerce, internet access, entertainment, etc. for communication. This has become common for the user to exchange and transfer the data. However people are still facing problems to use mobile devices because of its security issue. This paper deals with various security issues in mobile computing. It also covers all the basic points which are useful in mobile security issues such as categorisation of security issues, methods or tactics for success in security issues in mobile computing, security frameworks.
