The autonomous MuDR element of the Mutator (Mu) transposable element family of maize encodes at least two proteins, MURA and MURB. Based on amino acid sequence similarity, previous studies have reported that MURA is likely to be a transposase. The functional characterization of MURA has been hindered by the instability of its cDNA, mudrA, in Escherichia coli. In this study, we report the first ...

The Sungun porphyry copper deposit is located in northwestern Iran and is associated with diorite/granodiorite to quartz-monzonite of Miocene age, which intruded Eocene volcanosedimentary and Cretaceous carbonate rocks. Copper mineralization was accompanied by both potassic and phyllic alteration. Three main mineralization related alteration episodes (potassic, transition, and phyllic alteratio...

Hop Count based distance estimation is an important element for localization of devices in mobile ad hoc networks. Deriving distance estimates from hop counts is prone to error, especially in networks with low density. This paper shows that mobility can affect the accuracy of hop count based distance estimation. Two types of error are defined to describe and analyze the source of underestimatio...

Information-centric networking (ICN) separates the identifier and locator of network entities, providing a natural advantage in supporting mobility. To gain ICN to support mobility, an urgent challenge is problem practical implementation with performance optimization. Software-defined (SDN) can be regarded as infrastructure implement However, it difficult for centralized SDN controller quickly ...
