    Nonlinear spin transport in a rectifying ferromagnet/semiconductor Schottky contact (2015)
    American Physical Society (APS)
    Details
    Publication Date: 2015-08-08
    Description: Author(s): R. Jansen, A. Spiesser, H. Saito, and S. Yuasa The electrical creation and detection of spin accumulation in ferromagnet/semiconductor Schottky contacts that exhibit highly nonlinear and rectifying electrical transport is evaluated. If the spin accumulation in the semiconductor is small, the expression for the spin voltage is identical to that o… [Phys. Rev. B 92, 075304] Published Thu Aug 06, 2015

    Description: Author(s): T. Makino, Y. Segawa, A. Tsukazaki, H. Saito, S. Takeyama, S. Akasaka, K. Nakahara, and M. Kawasaki We report on the photoluminescence (PL) properties of Mg x Zn 1− x O/ZnO heterojunctions grown by plasma-assisted molecular-beam epitaxy. Influence of the applied magnetic field ( B ) on the radiative recombination of the two-dimensional electron gas (2DEG) is investigated up to 54 T. An increase in magnet... [Phys. Rev.

    Anisotropy of spin polarization and spin accumulation in Si/Al_{2}O_{3}/ferromagnet tunnel devices (2012)

    Publication Date: 2012-10-09
    Description: Author(s): S. Sharma, S. P. Dash, H. Saito, S. Yuasa, B. J. van Wees, and R. Jansen The contribution of the spin accumulation to tunneling anisotropy in Si/Al 2 O 3 /ferromagnet devices was investigated. Rotation of the magnetization of the ferromagnet from in-plane to perpendicular to the tunnel interface reveals a tunneling anisotropy that depends on the type of the ferromagnet (Fe o... [Phys. Rev.

    Osmotic activation of the HOG MAPK pathway via Ste11p MAPKKK: scaffold role of Pbs2p MAPKK (1997)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1997-06-13
    Description: Exposure of the yeast Saccharomyces cerevisiae to high extracellular osmolarity induces the Sln1p-Ypd1p-Ssk1p two-component osmosensor to activate a mitogen-activated protein (MAP) kinase cascade composed of the Ssk2p and Ssk22p MAP kinase kinase kinases (MAPKKKs), the Pbs2p MAPKK, and the Hog1p MAPK. A second osmosensor, Sho1p, also activated Pbs2p and Hog1p, but did so through the Ste11p MAPKKK. Although Ste11p also participates in the mating pheromone-responsive MAPK cascade, there was no detectable cross talk between these two pathways. The MAPKK Pbs2p bound to the Sho1p osmosensor, the MAPKKK Ste11p, and the MAPK Hog1p. Thus, Pbs2p may serve as a scaffold protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Posas, F -- Saito, H -- GM50909/GM/NIGMS NIH HHS/ -- GM53415/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1997 Jun 13;276(5319):1702-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Tumor Immunology, Dana-Farber Cancer Institute, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9180081" target="_blank"〉PubMed〈/a〉

    Activation of yeast PBS2 MAPKK by MAPKKKs or by binding of an SH3-containing osmosensor (1995)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1995-07-28
    Description: The role of mitogen-activated protein (MAP) kinase cascades in integrating distinct upstream signals was studied in yeast. Mutants that were not able to activate PBS2 MAP kinase kinase (MAPKK; Pbs2p) at high osmolarity were characterized. Pbs2p was activated by two independent signals that emanated from distinct cell-surface osmosensors. Pbs2p was activated by MAP kinase kinase kinases (MAPKKKs) Ssk2p and Ssk22p that are under the control of the SLN1-SSK1 two-component osmosensor. Alternatively, Pbs2p was activated by a mechanism that involves the binding of its amino terminal proline-rich motif to the Src homology 3 (SH3) domain of a putative transmembrane osmosensor Sho1p.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Maeda, T -- Takekawa, M -- Saito, H -- New York, N.Y. -- Science. 1995 Jul 28;269(5223):554-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Tumor Immunology, Dana-Farber Cancer Institute, Boston, MA 02115, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7624781" target="_blank"〉PubMed〈/a〉
