Using the projection operator technique, the exact homogeneous generalized master equation (HGME) for the relevant part of a distribution function (statistical operator) is derived. The exact (mass) operator governing the evolution of the relevant part of a distribution function and comprising arbitrary initial correlations is found. Neither the Bogolyubov principle of weakening of initial corr...

Memory institutions have been working to incorporate features into their digital collections that empower users to take ownership of cultural narratives. The advent of technologies like annotation tools and crowdsourced tagging have allowed libraries, archives, and museums to promote user content as part of an institutional narrative, albeit a somewhat tertiary one (Salomon, 2013). Collecting i...

Retaining glycosyltransferase enzymes retain the stereochemistry of the donor glycosidic linkage after transfer to an acceptor molecule. The mechanism these enzymes utilize to achieve retention of the anomeric stereochemistry has been a matter of much debate. Re-analysis of previously released structural data from retaining and inverting glycosyltransferases allows competing mechanistic proposa...

With the growing population and density in metropolitan areas, higher tendency to live in high-rise buildings, and increasing demand for parking lots, it seems necessary to excavate soil to construct underground spaces. During excavation work, as the height of the wall increases, special care should be taken to the wall stabilization to avoid any consequent damage including extensive property d...

This paper compares the use of Lisp and Prolog for the implementation of a functional grammar uniication system. To achieve this comparison, we have taken as a starting point Michael Elhadad's FUF system, which is written in Lisp and produced a much smaller and more eecient Prolog version (PFUF) retaining many of FUF's essential features. Our approach is based on a precompilation scheme that re...

The dynamic properties of a layer-oriented multi-conjugate adaptive optics system are examined. It is shown that such a system is stable and closes the loop. A simplified analysis of the achievable correction is presented, in order to define the conditions in which the layer-oriented approach is equivalent to other linear reconstruction schemes. It is found that this approach is equivalent to a...
