Designed by a physicist and a mathematician, the Hagia Sophia church in Istanbul,Turkey acted as an experimental test case in which advanced knowledge of geometrical constructs, sophisticated understanding of light behavior, and religious and cosmological beliefs combined to create a magnificent structure.While some of its design concepts are known, many remain hidden. Earthquakes have demolish...

Bacteriophage T4 consists of a head for protecting its genome and a sheathed tail for inserting its genome into a host. The tail terminates with a multiprotein baseplate that changes its conformation from a "high-energy" dome-shaped to a "low-energy" star-shaped structure during infection. Although these two structures represent different minima in the total energy landscape of the baseplate as...

The main purpose of this paper is to compare the results modal analysis for two types domes. first one a low-rise Schwedler dome. second high-rise geodesic dome subjected large displacement gradients and should be designed according geometrical nonlinear analysis. In case dome, linear sufficient. analysis, mass bars supporting structures was modeled as evenly distributed, while covering roof eq...

Reducing duplicated data of database backups is an important application scenario for data deduplication technology. NewSQL is an emerging database system and is now being used more and more widely. NewSQL systems need to improve data reliability by periodically backing up in-memory data, resulting in a lot of duplicated data. The traditional deduplication method is not optimized for the NewSQL...
