    Description: Author(s): Bohm-Jung Yang, Takahiro Morimoto, and Akira Furusaki In general, the stability of a band crossing point indicates the presence of a quantized topological number associated with it. In particular, the recent discovery of three-dimensional Dirac semimetals in Na 3 Bi and Cd 3 As 2 demonstrates that a Dirac point with fourfold degeneracy can be stable as long… [Phys. Rev.

    Description: Author(s): Bohm-Jung Yang, Mohammad Saeed Bahramy, Ryotaro Arita, Hiroki Isobe, Eun-Gook Moon, and Naoto Nagaosa We construct a general theory describing the topological quantum phase transitions in 3D systems with broken inversion symmetry. While the consideration of the system’s codimension generally predicts the appearance of a stable metallic phase between the normal and topological insulators, it is shown... [Phys. Rev.

    Description: Author(s): Hiroki Isobe, Bohm-Jung Yang, Andrey Chubukov, Jörg Schmalian, and Naoto Nagaosa We study the effects of Coulomb interaction between 2D Weyl fermions with anisotropic dispersion which displays relativistic dynamics along one direction and nonrelativistic dynamics along the other. Such a dispersion can be realized in phosphorene under electric field or strain, in TiO 2 / VO 2 superla… [Phys. Rev. Lett. 116, 076803] Published Thu Feb 18, 2016

    Description: Author(s): Bohm-Jung Yang and Naoto Nagaosa Because of the recent development of thin film and artificial superstructure growth techniques, it is possible to control the dimensionality of the system, smoothly between two and three dimensions. In this Letter we unveil the dimensional crossover of emergent topological phenomena in correlated to... [Phys. Rev. Lett. 112, 246402] Published Wed Jun 18, 2014

    Description: Polyadenylate [poly(A)] polymerase (PAP) catalyzes the addition of a polyadenosine tail to almost all eukaryotic messenger RNAs (mRNAs). The crystal structure of the PAP from Saccharomyces cerevisiae (Pap1) has been solved to 2.6 angstroms, both alone and in complex with 3'-deoxyadenosine triphosphate (3'-dATP). Like other nucleic acid polymerases, Pap1 is composed of three domains that encircle the active site. The arrangement of these domains, however, is quite different from that seen in polymerases that use a template to select and position their incoming nucleotides. The first two domains are functionally analogous to polymerase palm and fingers domains. The third domain is attached to the fingers domain and is known to interact with the single-stranded RNA primer. In the nucleotide complex, two molecules of 3'-dATP are bound to Pap1. One occupies the position of the incoming base, prior to its addition to the mRNA chain. The other is believed to occupy the position of the 3' end of the mRNA primer.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bard, J -- Zhelkovsky, A M -- Helmling, S -- Earnest, T N -- Moore, C L -- Bohm, A -- R01 GM57218-01A2/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Aug 25;289(5483):1346-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Boston Biomedical Research Institute, 64 Grove Street, Watertown, MA 02472, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10958780" target="_blank"〉PubMed〈/a〉

    Description: Author(s): Taekoo Oh, Hiroaki Ishizuka, and Bohm-Jung Yang Motivated by the recent experimental observation of anomalous magnetotransport properties near the Mott quantum critical point (QCP) of pyrochlore iridates, we study the generic topological band structure near QCP in the presence of magnetic field. We have found that the competition between differen... [Phys. Rev. B 98, 144409] Published Mon Oct 08, 2018

    Description: Macrophage colony-stimulating factor (M-CSF) triggers the development of cells of the monocyte-macrophage lineage and has a variety of stimulatory effects on mature cells of this class. The biologically active form of M-CSF is a disulfide-linked dimer that activates an intrinsic tyrosine kinase activity on the M-CSF receptor by inducing dimerization of the receptor molecules. The structure of a recombinant human M-CSF dimer, determined at 2.5 angstroms by x-ray crystallography, contains two bundles of four alpha helices laid end-to-end, with an interchain disulfide bond. Individual monomers of M-CSF show a close structural similarity to the cytokines granulocyte-macrophage colony-stimulating factor and human growth hormone. Both of these cytokines are monomeric in their active form, and their specific receptors lack intrinsic tyrosine kinase activity. The similarity of these structures suggests that the receptor binding determinants for all three cytokines may be similar.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pandit, J -- Bohm, A -- Jancarik, J -- Halenbeck, R -- Koths, K -- Kim, S H -- New York, N.Y. -- Science. 1992 Nov 20;258(5086):1358-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Structural Biology Division, Lawrence Berkeley Laboratory, Berkeley, CA 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1455231" target="_blank"〉PubMed〈/a〉

    Description: In prokaryotes and eukaryotes mobile genetic elements frequently disrupt the highly conservative structures of chromosomes, which are responsible for storage of genetic information. The factors determining the site for integration of such elements are still unknown. Transfer RNA (tRNA) genes are associated in a highly significant manner with different putative mobile genetic elements in the cellular slime mold Dictyostelium discoideum. These results suggest that tRNA genes in D. discoideum, and probably tRNA genes generally in lower eukaryotes, may function as genomic landmarks for the integration of different transposable elements in a strictly position-specific manner.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Marschalek, R -- Brechner, T -- Amon-Bohm, E -- Dingermann, T -- New York, N.Y. -- Science. 1989 Jun 23;244(4911):1493-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Biochemie der Medizinischen Fakultat, Universitat Erlangen-Nurnberg, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2567533" target="_blank"〉PubMed〈/a〉

    Description: The Mars Science Laboratory spacecraft, containing the Curiosity rover, was launched to Mars on 26 November 2011, and for most of the 253-day, 560-million-kilometer cruise to Mars, the Radiation Assessment Detector made detailed measurements of the energetic particle radiation environment inside the spacecraft. These data provide insights into the radiation hazards that would be associated with a human mission to Mars. We report measurements of the radiation dose, dose equivalent, and linear energy transfer spectra. The dose equivalent for even the shortest round-trip with current propulsion systems and comparable shielding is found to be 0.66 +/- 0.12 sievert.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Zeitlin, C -- Hassler, D M -- Cucinotta, F A -- Ehresmann, B -- Wimmer-Schweingruber, R F -- Brinza, D E -- Kang, S -- Weigle, G -- Bottcher, S -- Bohm, E -- Burmeister, S -- Guo, J -- Kohler, J -- Martin, C -- Posner, A -- Rafkin, S -- Reitz, G -- New York, N.Y. -- Science. 2013 May 31;340(6136):1080-4. doi: 10.1126/science.1235989.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Southwest Research Institute, Boulder, CO, USA. zeitlin@boulder.swri.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23723233" target="_blank"〉PubMed〈/a〉
