An efficient encoding approach by separating background/foreground videos from a single video is proposed for surveillance applications. The required bit-rate becomes less than a half of that by a standard H.264 approach. The reduction comes from the employment of the low resolution background pictures with a low frame-rate. In addition, the foreground video is automatically handled so that the...

background: clarithromycin resistance in helicbacter pylori has been found to be associated with point mutations in 23s rrna gene leads to reduced affinity of the antibiotic to its ribosomal target or changing the site of methylation. the aim of this study was to determine the most important point mutations in 23s rrna gene in h. pylori that are closely related to clarith-romycin resistance amo...

A (PNP)Ir fragment undergoes facile, room-temperature oxidative addition of C-H bonds in arenes and haloarenes in preference to aromatic carbon-halogen bonds. This preference, however, is determined to be kinetic in nature. Oxidative addition of C-Cl and C-Br is preferred thermodynamically. The products of the C-Cl or C-Br oxidative addition are separated from the C-H oxidative addition product...

This paper describes an improved, IEEE conforming oating-point addition algorithm. This algorithm has only one addition step involving the signi cand in the worst-case path, hence o ering a considerable speed advantage over the existing algorithms, which typically require two to three addition steps.

Solving constraints over the oating point numbers is a key issue in the process of software validation and veri cation. Techniques to solve such constraints on the basis of projection functions have been successfully developed. However, though correct, this approach can lead to slow convergence phenomena for very common constraints like addition and subtraction constraints. In this paper, we in...
