    Kinetic effect of toroidal rotation on the geodesic acoustic mode (2015)
    American Institute of Physics (AIP)
    Details
    Publication Date: 2015-01-06
    Description: Kinetic effects of the toroidal rotation on the geodesic acoustic mode are theoretically investigated. It is found that when the toroidal rotation increases, the damping rate increases in the weak rotation regime due to the rotation enhancement of wave-particle interaction, and it decreases in the strong rotation regime due to the reduction of the number of resonant particles. Theoretical results are consistent with the behaviors of the geodesic acoustic mode recently observed in DIII-D and ASDEX-Upgrade. The kinetic damping effect of the rotation on the geodesic acoustic mode may shed light on the regulation of turbulence through the controlling the toroidal rotation.

    Rapamycin-induced insulin resistance is mediated by mTORC2 loss and uncoupled from longevity (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-03-31
    Description: Rapamycin, an inhibitor of mechanistic target of rapamycin complex 1 (mTORC1), extends the life spans of yeast, flies, and mice. Calorie restriction, which increases life span and insulin sensitivity, is proposed to function by inhibition of mTORC1, yet paradoxically, chronic administration of rapamycin substantially impairs glucose tolerance and insulin action. We demonstrate that rapamycin disrupted a second mTOR complex, mTORC2, in vivo and that mTORC2 was required for the insulin-mediated suppression of hepatic gluconeogenesis. Further, decreased mTORC1 signaling was sufficient to extend life span independently from changes in glucose homeostasis, as female mice heterozygous for both mTOR and mLST8 exhibited decreased mTORC1 activity and extended life span but had normal glucose tolerance and insulin sensitivity. Thus, mTORC2 disruption is an important mediator of the effects of rapamycin in vivo.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3324089/" 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/PMC3324089/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lamming, Dudley W -- Ye, Lan -- Katajisto, Pekka -- Goncalves, Marcus D -- Saitoh, Maki -- Stevens, Deanna M -- Davis, James G -- Salmon, Adam B -- Richardson, Arlan -- Ahima, Rexford S -- Guertin, David A -- Sabatini, David M -- Baur, Joseph A -- 1F32AG032833-01A1/AG/NIA NIH HHS/ -- CA129105/CA/NCI NIH HHS/ -- F32 AG032833/AG/NIA NIH HHS/ -- P30DK19525/DK/NIDDK NIH HHS/ -- R01 CA129105/CA/NCI NIH HHS/ -- R01 CA129105-05/CA/NCI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Mar 30;335(6076):1638-43. doi: 10.1126/science.1215135.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Whitehead Institute for Biomedical Research, Cambridge, MA 02142, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22461615" target="_blank"〉PubMed〈/a〉

    Energy release of the 2013 M(w) 8.3 Sea of Okhotsk earthquake and deep slab stress heterogeneity (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-09-21
    Description: Earth's deepest earthquakes occur in subducting oceanic lithosphere, where temperatures are lower than in ambient mantle. On 24 May 2013, a magnitude 8.3 earthquake ruptured a 180-kilometer-long fault within the subducting Pacific plate about 609 kilometers below the Sea of Okhotsk. Global seismic P wave recordings indicate a radiated seismic energy of ~1.5 x 10(17) joules. A rupture velocity of ~4.0 to 4.5 kilometers/second is determined by back-projection of short-period P waves, and the fault width is constrained to give static stress drop estimates (~12 to 15 megapascals) compatible with theoretical radiation efficiency for crack models. A nearby aftershock had a stress drop one to two orders of magnitude higher, indicating large stress heterogeneity in the deep slab, and plausibly within the rupture process of the great event.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ye, Lingling -- Lay, Thorne -- Kanamori, Hiroo -- Koper, Keith D -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1380-4. doi: 10.1126/science.1242032.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth and Planetary Sciences, University of California Santa Cruz, Santa Cruz, CA 95064, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24052306" target="_blank"〉PubMed〈/a〉

    A single mutation in the prM protein of Zika virus contributes to fetal microcephaly (2017)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2017-11-17
    Description: Zika virus (ZIKV) has evolved into a global health threat because of its unexpected causal link to microcephaly. Phylogenetic analysis reveals that contemporary epidemic strains have accumulated multiple substitutions from their Asian ancestor. Here we show that a single serine-to-asparagine substitution [Ser 139 -〉Asn 139 (S139N)] in the viral polyprotein substantially increased ZIKV infectivity in both human and mouse neural progenitor cells (NPCs) and led to more severe microcephaly in the mouse fetus, as well as higher mortality rates in neonatal mice. Evolutionary analysis indicates that the S139N substitution arose before the 2013 outbreak in French Polynesia and has been stably maintained during subsequent spread to the Americas. This functional adaption makes ZIKV more virulent to human NPCs, thus contributing to the increased incidence of microcephaly in recent ZIKV epidemics.

    Different reaction mechanisms during mechanical alloying Ti50C50 and Ti33B67 (1996)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 80 (1996), S. 1910-1912

    Notes: Two different reaction mechanisms for Ti50C50 and Ti33B67 have been observed respectively during milling in a planetary ball mill. It is shown that a gradual reaction occurred during milling Ti50C50, while a self-sustained reaction was obtained during milling Ti33B67 under the same milling condition. Compared with the results of milling Ti50C50 in a spex mill, the difference in mechanism is suggested to be caused by the effect of plastic deformation on the changes of fine grains and internal strain during milling, and the different formation heat of TiC and TiB2, which is the driving force for the reactions. © 1996 American Institute of Physics.

    Formation mechanism of TiC by mechanical alloying (1994)

    Notes: Titanium carbide (TiC) has been synthesized by mechanically alloying the elemental powder mixture of titanium and graphite at composition of Ti1−xCx (x=0.35, 0.43, 0.50). Under the employed milling condition, the formation of TiC has been found to undergo an abrupt, exothermic reaction. The final product is TiC for x=0.43 and 0.50, and TiC+Ti (small amount) for x=0.35. It is suggested that this reaction appears to be a self-sustained high-temperature synthesis process. The initial milling stage seems to be an incubation duration for the reaction, and the mechanical impacts to be the ignition of the following abrupt reaction. It is believed that this type of reaction is an important mechanism for mechanical alloying of the highly exothermic alloy systems. © 1994 American Institute of Physics.

    Diverse rupture processes in the 2015 Peru deep earthquake doublet (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2016-06-25
    Description: Earthquakes in deeply subducted oceanic lithosphere can involve either brittle or dissipative ruptures. On 24 November 2015, two deep (606 and 622 km) magnitude 7.5 and 7.6 earthquakes occurred 316 s and 55 km apart. The first event (E1) was a brittle rupture with a sequence of comparable-size subevents extending unilaterally ~50 km southward with a rupture speed of ~4.5 km/s. This earthquake triggered several aftershocks to the north along with the other major event (E2), which had 40% larger seismic moment and the same duration (~20 s), but much smaller rupture area and lower rupture speed than E1, indicating a more dissipative rupture. A minor energy release ~12 s after E1 near the E2 hypocenter, possibly initiated by the S wave from E1, and a clear aftershock ~165 s after E1 also near the E2 hypocenter, suggest that E2 was likely dynamically triggered. Differences in deep earthquake rupture behavior are commonly attributed to variations in thermal state between subduction zones. However, the marked difference in rupture behavior of the nearby Peru doublet events suggests that local variations of stress state and material properties significantly contribute to diverse behavior of deep earthquakes.

    Ultrafast manipulation of mirror domain walls in a charge density wave (2018)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2018
    Description: 〈p〉Domain walls (DWs) are singularities in an ordered medium that often host exotic phenomena such as charge ordering, insulator-metal transition, or superconductivity. The ability to locally write and erase DWs is highly desirable, as it allows one to design material functionality by patterning DWs in specific configurations. We demonstrate such capability at room temperature in a charge density wave (CDW), a macroscopic condensate of electrons and phonons, in ultrathin 1〈i〉T〈/i〉-TaS〈sub〉2〈/sub〉. A single femtosecond light pulse is shown to locally inject or remove mirror DWs in the CDW condensate, with probabilities tunable by pulse energy and temperature. Using time-resolved electron diffraction, we are able to simultaneously track anti-synchronized CDW amplitude oscillations from both the lattice and the condensate, where photoinjected DWs lead to a red-shifted frequency. Our demonstration of reversible DW manipulation may pave new ways for engineering correlated material systems with light.〈/p〉
