BACKGROUND Today, there are more than a hundred times as many sequenced prokaryotic genomes than were present in the year 2000. The economical sequencing of genomic DNA has facilitated a whole new approach to microbial genomics. The real power of genomics is manifested through comparative genomics that can reveal strain specific characteristics, diversity within species and many other aspects. ...

A suite of Moderate-Resolution Imaging Spectroradiometer (MODIS) snow products at various spatial and temporal resolutions from the Terra satellite has been available since February 2000. Standard products include daily and 8-day composite 500 m resolution swath and tile products (which include fractional snow cover (FSC) and snow albedo), and 0Ð05° resolution products on a climate-modelling gr...

BACKGROUND We recently reported that cardiomyocytes could be differentiated from bone marrow mesenchymal stem cells in vitro by 5-azacytidine treatment. In native cardiomyocytes, adrenergic and muscarinic receptors play crucial roles in mediating heart rate, conduction velocity, contractility, and cardiac hypertrophy. We investigated whether these receptors are expressed in differentiated CMG c...

the linear adiabatic pulsation-periods of mira variable stars have been derived. approximately 2701[1]models were calculated for m = 0.7 mθ to 2 mθ stars with radii from 180 rθ to 340 rθ and luminosities from 2800 lθ to 10,000 lθ. the chemical composition of all models is (x,z) = (0.7,0.02). from the result of this study, linear relations on luminosity-period-mass relationship and luminosity-pe...

we have studied the effect of hypothetical cosmions on the core stability of main sequence stars (of populations i and ii). cosmions, with a mass of 4-10 gev/c2 and a scattering cross section with nucleons of approximately 10-36 cm2 could prevail in transporting heat in the stellar cores. raby [17] showed the existence of a local thermal instability caused by the presence of cosmions in the sol...

The role of Cdc45 in genomic duplication has remained unclear since its initial identification as an essential replication factor. Recent structural studies of Cdc45 and the evolutionarily-related archaeal GAN and bacterial RecJ nucleases have provided fresh insight into its function as co-activator of the MCM helicase. The CMG helicase of the last archaeal/eukaryotic ancestor might have harbou...

In this paper, we propose Viola, which can define CMG grammar graphically and execute a visual system on the same screen. By using Viola, the user can define various visual systems interactively. It became possible to define grammars using graphical expressions and construct visual systems dynamically, while checking the grammar at the execution time. We have actually implemented Viola in Java ...

an extended star is a tree which has only one vertex with degree larger than two. the -center problem in a graph  asks to find a subset  of the vertices of  of cardinality  such that the maximum weighted distances from  to all vertices is minimized. in this paper we consider the -center problem on the unweighted extended stars, and present some properties to find solution.
