    Evolution of inhomogeneously broadened spin-noise spectrum with ac drive (2015)
    American Physical Society (APS)
    Details
    Publication Date: 2015-04-10
    Description: Author(s): Z. Yue and M. E. Raikh In the presence of random hyperfine fields, the noise spectrum, 〈δs ω 2 〉, of a spin ensemble represents a narrow peak centered at ω=0 and a broad wing reflecting the distribution of the hyperfine fields. In the presence of an ac drive, the dynamics of a single spin acquires additional harmonics at fre... [Phys. Rev. B 91, 155301] Published Thu Apr 09, 2015

    Description: Author(s): Z. Yue, V. V. Mkhitaryan, and M. E. Raikh We study analytically the free induction decay and the spin echo decay originating from the localized carriers moving between the sites which host random magnetic fields. Due to disorder in the site positions and energies, the on-site residence times, τ , are widely spread according to the Lévy distr… [Phys. Rev. B 93, 195319] Published Tue May 31, 2016

    Global mapping and analysis of lunar wrinkle ridges (2015)
    Wiley
    Details
    Publication Date: 2015-04-30
    Description: Lunar wrinkle ridges were globally mapped and the morphological parameters, including length, width, elevation offset, and orientation, were also calculated. The results include the identification of 2,839 segments with a total length of 25,560.69 km, and the mean width, height, elevation offset, and orientation of all the wrinkle ridges are 3.70 km, 0.31 km, 46.37 m, and −1.99°, respectively after weighted by the length. Based on their morphologies and distribution, lunar wrinkle ridges were classified into three categories: concentric, parallel, and isolated ridges and most of the wrinkle ridges are distributed over basalts, although a few extend to nearby highlands. The relations between the morphological parameters were further quantitatively analyzed, and a similar linear correlation between the width and height was found in each class of lunar ridges, implying that small and large ridges were formed as a continuum and that the three classes of ridges were probably formed by some common processes. Finally, the relations between the lunar wrinkle ridges and other geomorphic phenomena were analyzed, indicating that purely volcanic origin or buried pre-mare structures are difficult to reconcile with the investigation. In addition, the consistency between the occurrence of the lunar wrinkle ridges and the some thickness of lunar maria indicates that the formation of lunar wrinkle ridges are closely related to the lunar maria; however, the statistical NW or NE orientation of each class of lunar wrinkle ridges also suggests a suitable global stress field involved in their formation process.

    Climbing-inspired twining electrodes using shape memory for peripheral nerve stimulation and recording (2019)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2019
    Description: 〈p〉Peripheral neuromodulation has been widely used throughout clinical practices and basic neuroscience research. However, the mechanical and geometrical mismatches at current electrode-nerve interfaces and complicated surgical implantation often induce irreversible neural damage, such as axonal degradation. Here, compatible with traditional 2D planar processing, we propose a 3D twining electrode by integrating stretchable mesh serpentine wires onto a flexible shape memory substrate, which has permanent shape reconfigurability (from 2D to 3D), distinct elastic modulus controllability (from ~100 MPa to ~300 kPa), and shape memory recoverability at body temperature. Similar to the climbing process of twining plants, the temporarily flattened 2D stiff twining electrode can naturally self-climb onto nerves driven by 37°C normal saline and form 3D flexible neural interfaces with minimal constraint on the deforming nerves. In vivo animal experiments, including right vagus nerve stimulation for reducing the heart rate and action potential recording of the sciatic nerve, demonstrate the potential clinical utility.〈/p〉

    Identification of SLEEPLESS, a sleep-promoting factor (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-07-19
    Description: Sleep is an essential process conserved from flies to humans. The importance of sleep is underscored by its tight homeostatic control. Through a forward genetic screen, we identified a gene, sleepless, required for sleep in Drosophila. The sleepless gene encodes a brain-enriched, glycosylphosphatidylinositol-anchored protein. Loss of SLEEPLESS protein caused an extreme (〉80%) reduction in sleep; a moderate reduction in SLEEPLESS had minimal effects on baseline sleep but markedly reduced the amount of recovery sleep after sleep deprivation. Genetic and molecular analyses revealed that quiver, a mutation that impairs Shaker-dependent potassium current, is an allele of sleepless. Consistent with this finding, Shaker protein levels were reduced in sleepless mutants. We propose that SLEEPLESS is a signaling molecule that connects sleep drive to lowered membrane excitability.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2771549/" 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/PMC2771549/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Koh, Kyunghee -- Joiner, William J -- Wu, Mark N -- Yue, Zhifeng -- Smith, Corinne J -- Sehgal, Amita -- AG017628/AG/NIA NIH HHS/ -- P01 AG017628/AG/NIA NIH HHS/ -- P01 AG017628-070004/AG/NIA NIH HHS/ -- R01 NS072431/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Jul 18;321(5887):372-6. doi: 10.1126/science.1155942.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Neuroscience, University of Pennsylvania, Philadelphia, PA 19104, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18635795" target="_blank"〉PubMed〈/a〉
