    Five-band microwave radiometer system for noninvasive brain temperature measurement in newborn babies: Phantom experiment and confidence interval (2011)
    Wiley
    Details
    Publication Date: 2011-11-19
    Description: Clinical trials of hypothermic brain treatment for newborn babies are currently hindered by the difficulty in measuring deep brain temperatures. As one of the possible methods for noninvasive and continuous temperature monitoring that is completely passive and inherently safe is passive microwave radiometry (MWR). We have developed a five-band microwave radiometer system with a single dual-polarized, rectangular waveguide antenna operating within the 1–4 GHz range and a method for retrieving the temperature profile from five radiometric brightness temperatures. This paper addresses (1) the temperature calibration for five microwave receivers, (2) the measurement experiment using a phantom model that mimics the temperature profile in a newborn baby, and (3) the feasibility for noninvasive monitoring of deep brain temperatures. Temperature resolutions were 0.103, 0.129, 0.138, 0.105 and 0.111 K for 1.2, 1.65, 2.3, 3.0 and 3.6 GHz receivers, respectively. The precision of temperature estimation (2σ confidence interval) was about 0.7°C at a 5-cm depth from the phantom surface. Accuracy, which is the difference between the estimated temperature using this system and the measured temperature by a thermocouple at a depth of 5 cm, was about 2°C. The current result is not satisfactory for clinical application because the clinical requirement for accuracy must be better than 1°C for both precision and accuracy at a depth of 5 cm. Since a couple of possible causes for this inaccuracy have been identified, we believe that the system can take a step closer to the clinical application of MWR for hypothermic rescue treatment.

    Phase-coherent amplification of matter waves (1999)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1999-12-22
    Description: Phase-coherent matter-wave amplification was demonstrated using Bose- Einstein-condensed rubidium-87 atoms. A small seed matter wave was created with coherent optical Bragg diffraction. Amplification of this seed matter wave was achieved by using the initial condensate as a gain medium through the superradiance effect. The coherence properties of the amplified matter wave, studied with a matter-wave interferometer, were shown to be locked to those of the initial seed wave. The active matter-wave device demonstrated here has great potential in the fields of atom optics, atom lithography, and precision measurements.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kozuma -- Suzuki -- Torii -- Sugiura -- Kuga -- Hagley -- Deng -- New York, N.Y. -- Science. 1999 Dec 17;286(5448):2309-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Physics, University of Tokyo, 3-8-1 Komaba, Meguro-ku, Tokyo 153-8902, Japan.

    MARCKS-like protein is an initiating molecule in axolotl appendage regeneration (2016)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2016-03-05
    Description: Identifying key molecules that launch regeneration has been a long-sought goal. Multiple regenerative animals show an initial wound-associated proliferative response that transits into sustained proliferation if a considerable portion of the body part has been removed. In the axolotl, appendage amputation initiates a round of wound-associated cell cycle induction followed by continued proliferation that is dependent on nerve-derived signals. A wound-associated molecule that triggers the initial proliferative response to launch regeneration has remained obscure. Here, using an expression cloning strategy followed by in vivo gain- and loss-of-function assays, we identified axolotl MARCKS-like protein (MLP) as an extracellularly released factor that induces the initial cell cycle response during axolotl appendage regeneration. The identification of a regeneration-initiating molecule opens the possibility of understanding how to elicit regeneration in other animals.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4795554/" 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/PMC4795554/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sugiura, Takuji -- Wang, Heng -- Barsacchi, Rico -- Simon, Andras -- Tanaka, Elly M -- England -- Nature. 2016 Mar 10;531(7593):237-40. doi: 10.1038/nature16974.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉DFG Research Center for Regenerative Therapies (CRTD), Technische Universitat Dresden, Fetscherstrasse 105, 01307 Dresden, Germany. ; Max Planck Institute for Molecular Cell Biology and Genetics, Pfotenhauerstrasse 108, 01307 Dresden, Germany. ; Karolinska Institute, Department of Cell and Molecular Biology, Centre of Developmental Biology for Regenerative Medicine, SE-171 77 Stockholm, Sweden.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/26934225" target="_blank"〉PubMed〈/a〉

    Geochemical indicator of tectonic stress resulting in an earthquake in central Japan, 1984 (1985)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1985-09-20
    Description: Conspicuous changes in gas composition were observed at a fumarole and a mineral spring just before the occurrence of an inland earthquake (magnitude, 6.8) in central Japan in September 1984; the fumarole and spring were 9 and 50 kilometers, respectively, from the earthquake's epicenter. Deep-seated fluids emitted as a result of the compressional stress of the earth tide had been observed previously at this mineral spring and at a lava lake in Hawaii. By analogy, the gas anomaly observed before the earthquake in Japan probably resulted from deepseated fluids being squeezed to the surface by the tectonic stress that caused the earthquake.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sugisaki, R -- Sugiura, T -- New York, N.Y. -- Science. 1985 Sep 20;229(4719):1261-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17770815" target="_blank"〉PubMed〈/a〉

    Negative-ion formation from positive ion by two-electron transfer from an alkali-metal target (1992)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 63 (1992), S. 1958-1965

    Notes: To examine two-electron transfer producing negative ions from positive ions, an apparatus using an alkali-metal target has been developed. Positive ions formed by electron impact in an ion source collided with alkali-metal vapor in a target chamber. Negative ions formed by two-electron transfer have been analyzed with a single-focusing mass spectrometer. Precursor positive ions and product negative ions have been identified from the apparent masses in the negative-ion spectra. Using the target density dependence of the negative-ion intensity, the processes of negative-ion formation were determined to be double-electron transfer in one collision or successive single-electron transfer in two collisions. The cross section of these processes has been estimated from the peak area of positive- and negative-ion spectra and the target density evaluated using the vapor-pressure curve as a function of the temperature of the alkali-metal cell. A cross section for He−-ion formation in the Cs target with successive single-electron transfer have been evaluated to be 1.40×10−30±0.2 cm4 at a collision energy of 2.0 keV, which showed the fair agreement with the values reported by Donnally and Thoeming [Phys. Rev. 159, 87 (1967)]. The double-electron transfer cross section for C2−-ion formation from a C2+ ion with a Cs target has been evaluated as 7.03×10−18±0.1 cm2 at 3.0 keV. For O−-ion formation from O2+ ions, four broad peaks were observed due to the kinetic energy releases at dissociation which were 7.3, 3.4, 1.1, and 0.014 eV at full width at half maximum. Since the kinetic energy releases of the broad peaks corresponded with those by Peterson and Bae [Phys. Rev. A 30, 2807 (1984)], the peak extents have been explained as the dissociations of the excited neutral formed from exothermic neutralization. This two-electron transfer from an alkali-metal target offers a good advantage for the determination of the dissociation mechanism for excited neutral particles by means of the negative-ion detection method.
