    High-fidelity readout scheme for rare-earth solid-state quantum computing (2015)
    American Physical Society (APS)
    Details
    Publication Date: 2015-08-11
    Description: Author(s): A. Walther, L. Rippe, Y. Yan, J. Karlsson, D. Serrano, A. N. Nilsson, S. Bengtsson, and S. Kröll We propose and analyze a high-fidelity readout scheme for a single-instance approach to quantum computing in rare-earth-ion-doped crystals. The scheme is based on using different elements as qubit and readout ions, where the readout ions are doped into the material at a much lower concentration than… [Phys. Rev.

    Description: Author(s): A. Walther, U. Poschinger, F. Ziesel, M. Hettrich, A. Wiens, J. Welzel, and F. Schmidt-Kaler It is expected that ion-trap quantum computing can be made scalable through protocols that make use of transport of ion qubits between subregions within the ion trap. In this scenario, any magnetic field inhomogeneity the ion experiences during the transport may lead to dephasing and loss of fidelit... [Phys. Rev. A 83, 062329] Published Thu Jun 23, 2011

    Functional genomic screen reveals genes involved in lipid-droplet formation and utilization (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-04-15
    Description: Eukaryotic cells store neutral lipids in cytoplasmic lipid droplets enclosed in a monolayer of phospholipids and associated proteins. These dynamic organelles serve as the principal reservoirs for storing cellular energy and for the building blocks for membrane lipids. Excessive lipid accumulation in cells is a central feature of obesity, diabetes and atherosclerosis, yet remarkably little is known about lipid-droplet cell biology. Here we show, by means of a genome-wide RNA interference (RNAi) screen in Drosophila S2 cells that about 1.5% of all genes function in lipid-droplet formation and regulation. The phenotypes of the gene knockdowns sorted into five distinct phenotypic classes. Genes encoding enzymes of phospholipid biosynthesis proved to be determinants of lipid-droplet size and number, suggesting that the phospholipid composition of the monolayer profoundly affects droplet morphology and lipid utilization. A subset of the Arf1-COPI vesicular transport proteins also regulated droplet morphology and lipid utilization, thereby identifying a previously unrecognized function for this machinery. These phenotypes are conserved in mammalian cells, suggesting that insights from these studies are likely to be central to our understanding of human diseases involving excessive lipid storage.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2734507/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2734507/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Guo, Yi -- Walther, Tobias C -- Rao, Meghana -- Stuurman, Nico -- Goshima, Gohta -- Terayama, Koji -- Wong, Jinny S -- Vale, Ronald D -- Walter, Peter -- Farese, Robert V -- R21 DK078254/DK/NIDDK NIH HHS/ -- R21 DK078254-01/DK/NIDDK NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2008 May 29;453(7195):657-61. doi: 10.1038/nature06928.

    Platelet-derived serotonin mediates liver regeneration (2006)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2006-04-08
    Description: The liver can regenerate its volume after major tissue loss. In a mouse model of liver regeneration, thrombocytopenia, or impaired platelet activity resulted in the failure to initiate cellular proliferation in the liver. Platelets are major carriers of serotonin in the blood. In thrombocytopenic mice, a serotonin agonist reconstituted liver proliferation. The expression of 5-HT2A and 2B subtype serotonin receptors in the liver increased after hepatectomy. Antagonists of 5-HT2A and 2B receptors inhibited liver regeneration. Liver regeneration was also blunted in mice lacking tryptophan hydroxylase 1, which is the rate-limiting enzyme for the synthesis of peripheral serotonin. This failure of regeneration was rescued by reloading serotonin-free platelets with a serotonin precursor molecule. These results suggest that platelet-derived serotonin is involved in the initiation of liver regeneration.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lesurtel, Mickael -- Graf, Rolf -- Aleil, Boris -- Walther, Diego J -- Tian, Yinghua -- Jochum, Wolfram -- Gachet, Christian -- Bader, Michael -- Clavien, Pierre-Alain -- New York, N.Y. -- Science. 2006 Apr 7;312(5770):104-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Visceral and Transplantation Surgery, University Hospital of Zurich, Switzerland.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16601191" target="_blank"〉PubMed〈/a〉

    Nanotubular highways for intercellular organelle transport (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-14
    Description: Cell-to-cell communication is a crucial prerequisite for the development and maintenance of multicellular organisms. To date, diverse mechanisms of intercellular exchange of information have been documented, including chemical synapses, gap junctions, and plasmodesmata. Here, we describe highly sensitive nanotubular structures formed de novo between cells that create complex networks. These structures facilitate the selective transfer of membrane vesicles and organelles but seem to impede the flow of small molecules. Accordingly, we propose a novel biological principle of cell-to-cell interaction based on membrane continuity and intercellular transfer of organelles.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rustom, Amin -- Saffrich, Rainer -- Markovic, Ivanka -- Walther, Paul -- Gerdes, Hans-Hermann -- New York, N.Y. -- Science. 2004 Feb 13;303(5660):1007-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Interdisciplinary Center of Neuroscience (IZN), Institute of Neurobiology, University of Heidelberg, INF 364, Heidelberg 69120, Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14963329" target="_blank"〉PubMed〈/a〉
