    Beschreibung: The vertical seismic profile, acquired with an array of 3C receivers and either a single source or several arranged in a multi-component configuration, provides an ideal high fidelity calibration tool for seismic projects involved in the application of seismic anisotropy. This book catalogues the majority of specialized tools necessary to work with P-P, P-S and S-S data from such Vertical seismic profiling surveys at the acquisition design, processing and interpretation stages. In particular, it discusses 3C, 4C, 6C and 9C Vertical seismic profiling, marine and land surveys with near and multiple offsets (walkways), azimuths (walkarounds) or a combination of both. These are considered for TIH or TIV flavours of seismic anisotropy arising from cracks, fractures, sedimentary layering, and shales. The anisotropic adaptation of familiar seismic methods for velocity analysis and inversion, reflected amplitude interpretation, are given together with more multi-component specific algorithms based upon the principles dictated by the vector convolutional model. Thus, multi-component methods are described that provide tests and compensation for source or receiver vector fidelity, tool rotation correction, layer stripping, near-surface correction, wavefield separation, and the Alford rotation with its variants. The work will be of interest to geophysicists involved in research or the application of seismic anisotropy using multi-component seismic. CONTENTS 1. Introduction. 2. Anisotropic replacement media. 3. Fundamentals of seismic anisotropy analysis. 4. Pre-requisites for near-offset Vertical seismic profiling analysis. 5.

    Beschreibung: Following the breakthrough in the last decade in identifying the key parameters for time and depth imaging in anisotropic media and developing practical methodologies for estimating them from seismic data, this title primarily focuses on the far reaching exploration benefits of anisotropic processing. This volume provides the first comprehensive description of reflection seismic signatures and processing methods in anisotropic media. It identifies the key parameters for time and depth imaging in transversely isotropic media and describes practical methodologies for estimating them from seismic data. Also, it contains a thorough discussion of the important issues of uniqueness and stability of seismic velocity analysis in the presence of anisotropy. The book contains a complete description of anisotropic imaging methods, from the theoretical background to algorithms to implementation issues. Numerous applications to synthetic and field data illustrate the improvements achieved by the anisotropic processing and the possibility of using the estimated anisotropic parameters in lithology discrimination.

    Hierarchical self-assembly of F-actin and cationic lipid complexes: stacked three-layer tubule networks (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2000-06-17
    Beschreibung: We describe a distinct type of spontaneous hierarchical self-assembly of cytoskeletal filamentous actin (F-actin), a highly charged polyelectrolyte, and cationic lipid membranes. On the mesoscopic length scale, confocal microscopy reveals ribbonlike tubule structures that connect to form a network of tubules on the macroscopic scale (more than 100 micrometers). Within the tubules, on the 0.5- to 50-nanometer length scale, x-ray diffraction reveals an unusual structure consisting of osmotically swollen stacks of composite membranes with no direct analog in simple amphiphilic systems. The composite membrane is composed of three layers, a lipid bilayer sandwiched between two layers of actin, and is reminiscent of multilayered bacterial cell walls that exist far from equilibrium. Electron microscopy reveals that the actin layer consists of laterally locked F-actin filaments forming an anisotropic two-dimensional tethered crystal that appears to be the origin of the tubule formation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wong, G C -- Tang, J X -- Lin, A -- Li, Y -- Janmey, P A -- Safinya, C R -- AR38910/AR/NIAMS NIH HHS/ -- GM59288/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2000 Jun 16;288(5473):2035-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Materials Department, University of California, Santa Barbara, CA 93106, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/10856215" target="_blank"〉PubMed〈/a〉

    Photoinduced conversion of silver nanospheres to nanoprisms (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2001-12-01
    Beschreibung: A photoinduced method for converting large quantities of silver nanospheres into triangular nanoprisms is reported. The photo-process has been characterized by time-dependent ultraviolet-visible spectroscopy and transmission electron microscopy, allowing for the observation of several key intermediates in and characteristics of the conversion process. This light-driven process results in a colloid with distinctive optical properties that directly relate to the nanoprism shape of the particles. Theoretical calculations coupled with experimental observations allow for the assignment of the nanoprism plasmon bands and for the first identification of two distinct quadrupole plasmon resonances for a nanoparticle. Unlike the spherical particles they are derived from that Rayleigh light-scatter in the blue, these nanoprisms exhibit scattering in the red, which could be useful in developing multicolor diagnostic labels on the basis not only of nanoparticle composition and size but also of shape.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jin, R -- Cao, Y -- Mirkin, C A -- Kelly, K L -- Schatz, G C -- Zheng, J G -- New York, N.Y. -- Science. 2001 Nov 30;294(5548):1901-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Institute for Nanotechnology, Department of Materials Science and Engineering, Northwestern University, 2145 Sheridan Road, Evanston, IL 60208, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11729310" target="_blank"〉PubMed〈/a〉

    Colloidal nanocrystal shape and size control: the case of cobalt (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2001-03-17
    Beschreibung: We show that a relatively simple approach for controlling the colloidal synthesis of anisotropic cadmium selenide semiconductor nanorods can be extended to the size-controlled preparation of magnetic cobalt nanorods as well as spherically shaped nanocrystals. This approach helps define a minimum feature set needed to separately control the sizes and shapes of nanocrystals. The resulting cobalt nanocrystals produce interesting two- and three-dimensional superstructures, including ribbons of nanorods.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Puntes, V F -- Krishnan, K M -- Alivisatos, A P -- 1 R01 RR-14891-01/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 2001 Mar 16;291(5511):2115-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, University of California at Berkeley, Berkeley, CA 94720, USA. vfpuntes@lbl.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11251109" target="_blank"〉PubMed〈/a〉

    Wind as a long-distance dispersal vehicle in the Southern Hemisphere (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2004-05-25
    Beschreibung: Anisotropic (direction-dependent) long-distance dispersal (LDD) by wind has been invoked to explain the strong floristic affinities shared among landmasses in the Southern Hemisphere. Its contribution has not yet been systematically tested because of the previous lack of global data on winds. We used global winds coverage from the National Aeronautics and Space Administration SeaWinds scatterometer to test whether floristic similarities of Southern Hemisphere moss, liverwort, lichen, and pteridophyte floras conform better with (i) the anisotropic LDD hypothesis, which predicts that connection by "wind highways" increases floristic similarities, or (ii) a direction-independent LDD hypothesis, which predicts that floristic similarities among sites increase with geographic proximity. We found a stronger correlation of floristic similarities with wind connectivity than with geographic proximities, which supports the idea that wind is a dispersal vehicle for many organisms in the Southern Hemisphere.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Munoz, Jesus -- Felicisimo, Angel M -- Cabezas, Francisco -- Burgaz, Ana R -- Martinez, Isabel -- New York, N.Y. -- Science. 2004 May 21;304(5674):1144-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Real Jardin Botanico, Plaza de Murillo 2, 28014 Madrid, Spain. jmunoz@ma-rjb.csic.es〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15155945" target="_blank"〉PubMed〈/a〉

    Probing protein electrostatics with a synthetic fluorescent amino acid (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2002-06-01
    Beschreibung: Electrostatics affect virtually all aspects of protein structure and activity and are particularly important in proteins whose primary function is to stabilize charge. Here we introduce a fluorescent amino acid, Aladan, which can probe the electrostatic character of a protein at multiple sites. Aladan is exceptionally sensitive to the polarity of its surroundings and can be incorporated site-selectively at buried and exposed sites, in both soluble and membrane proteins. Steady-state and time-resolved fluorescence measurements of Aladan residues at different buried and exposed sites in the B1 domain of protein G suggest that its interior is polar and heterogeneous.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cohen, Bruce E -- McAnaney, Tim B -- Park, Eun Sun -- Jan, Yuh Nung -- Boxer, Steven G -- Jan, Lily Yeh -- GM27738/GM/NIGMS NIH HHS/ -- MH65334/MH/NIMH NIH HHS/ -- New York, N.Y. -- Science. 2002 May 31;296(5573):1700-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute and Departments of Physiology and Biochemistry, University of California San Francisco, San Francisco, CA 94143, USA. bcohen@itsa.ucsf.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12040199" target="_blank"〉PubMed〈/a〉
