Recently, a concept of digital metamaterials has been proposed to manipulate field distribution through proper spatial mixtures of digital metamaterial bits. Here, we present a design of 2-bit digitally-controlled coding metasurface that can effectively modulate the scattered electromagnetic wave and realize different far-field beams. Each meta-atom of this metasurface integrates two pin diodes...

Draft genome sequences of three P. aeruginosa strains from the PA7 clade are presented here. Their lengths are 6.36 (EML528), 6.44 (EML545), and 6.33 Mb (EML548). Comparisons with the PA7 genome showed 5,113 conserved coding sequences (CDSs), and significant numbers of strain-specific CDSs. Their analysis will improve our understanding of this highly divergent clade.

Based on whole mtDNA sequencing of 14 samples from Northern Island Melanesia, we characterize three formerly unresolved branches of macrohaplogroup M that we call haplogroups M27, M28, and M29. Our 1,399 mtDNA control region sequences and a literature search indicate these haplogroups have extremely limited geographical distributions. Their coding region variation suggests diversification times...

A set of 96 complete mtDNA sequences that belong to the three major African haplogroups (L1, L2, and L3) was analyzed to determine if mtDNA has evolved as a molecular clock. Likelihood ratio tests (LRTs) were carried out with each of the haplogroups and with combined haplogroup sequence sets. Evolution has not been clock-like, neither for the coding region nor for the control region, in combine...

The human genome is often portrayed as consisting of three sequence types, each distinguished by their mode of evolution. Purifying selection is estimated to act on 2.5-5.0% of the genome, whereas virtually all remaining sequence is considered to have evolved neutrally and to be devoid of functionality. The third mode of evolution, positive selection of advantageous changes, is considered rare....

We report the 3.0-Mb draft genome sequence of Brevundimonas abyssalis strain TAR-001(T), isolated from deep-sea floor sediment. The draft genome sequence of strain TAR-001(T) consists of 2,979,700 bp in 128 contigs, with a G+C content of 68.2%, 2,946 potential coding sequences (CDS), 3 rRNAs, and 41 tRNAs.

The recently introduced bacterial species Chlamydia gallinacea is known to occur in domestic poultry and other birds. Its potential as an avian pathogen and zoonotic agent is under investigation. The whole-genome sequence of its type strain, 08-1274/3, consists of a 1,059,583-bp chromosome with 914 protein-coding sequences (CDSs) and a plasmid (p1274) comprising 7,619 bp with 9 CDSs.

The flanking regions and the end of the chloroplast ribosomal unit of Chlamydomonas reinhardii have been sequenced. The upstream region of the ribosomal unit contains three open reading frames coding for 111, 117 and 124 amino acids, respectively. The latter polypeptide is partially related to the ribosomal protein L16 of E. coli. Two of the open reading frames overlap each other and are orient...

Recently, an unusual gene structure has been described in species of the genus Thermus, in which the rpmH (ribosomal protein L34) coding sequence was found to be entirely overlapped by the unusually large rnpA (RNase P protein subunit) sequence. Gene overlap is common in viruses, but has not been seen to this extent in any bacterium.

We report the 3.2-Mb draft genome sequence of Brevundimonas denitrificans strain TAR-002T, isolated from deep-sea floor sediment. The draft genome sequence of strain TAR-002T consists of 3,231,216 bp in 44 contigs, with a G+C content of 68.47%, 3,866 potential coding sequences (CDSs), 3 rRNAs, and 45 tRNAs.
