    High-rate coseismic displacements from tightly integrated processing of raw GPS and accelerometer data (2013)
    Oxford University Press
    Details
    Publication Date: 2013-09-10
    Description: High-rate GPS and seismic sensors are mutually contributing to seismological applications for capturing earthquake-induced coseismic displacements. In this study, we propose an approach for tightly integrating GPS and strong motion data on raw observation level to increase the quality of the derived displacements. The performance of the proposed approach is demonstrated using 5 Hz high-rate GPS and 200 Hz strong motion data collected during the El Mayor–Cucapah earthquake ( M w 7.2, 2010 April 4) in Baja California, Mexico. The new approach not only takes advantages of both GPS and strong motion sensors, but also improves the reliability of the displacement by enhancing GPS integer-cycle phase ambiguity resolution, which is very critical for deriving displacements with highest quality.

    Genetic manipulation of lignin reduces recalcitrance and improves ethanol production from switchgrass [Plant Biology] (2011)
    National Academy of Sciences
    Details
    Publication Date: 2011-03-02
    Description: Switchgrass is a leading dedicated bioenergy feedstock in the United States because it is a native, high-yielding, perennial prairie grass with a broad cultivation range and low agronomic input requirements. Biomass conversion research has developed processes for production of ethanol and other biofuels, but they remain costly primarily because of the intrinsic recalcitrance of biomass. We show here that genetic modification of switchgrass can produce phenotypically normal plants that have reduced thermal-chemical (≤180 °C), enzymatic, and microbial recalcitrance. Down-regulation of the switchgrass caffeic acid O-methyltransferase gene decreases lignin content modestly, reduces the syringyl:guaiacyl lignin monomer ratio, improves forage quality, and, most importantly, increases the ethanol yield by up to 38% using conventional biomass fermentation processes. The down-regulated lines require less severe pretreatment and 300–400% lower cellulase dosages for equivalent product yields using simultaneous saccharification and fermentation with yeast. Furthermore, fermentation of diluted acid-pretreated transgenic switchgrass using Clostridium thermocellum with no added enzymes showed better product yields than obtained with unmodified switchgrass. Therefore, this apparent reduction in the recalcitrance of transgenic switchgrass has the potential to lower processing costs for biomass fermentation-derived fuels and chemicals significantly. Alternatively, such modified transgenic switchgrass lines should yield significantly more fermentation chemicals per hectare under identical process conditions.

    A calmodulin-related protein that suppresses posttranscriptional gene silencing in plants (2000)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2000-10-06
    Description: Posttranscriptional gene silencing (PTGS) is an ancient eukaryotic regulatory mechanism in which a particular RNA sequence is targeted and destroyed. The helper component-proteinase (HC-Pro) of plant potyviruses suppresses PTGS in plants. Using a yeast two-hybrid system, we identified a calmodulin-related protein (termed rgs-CaM) that interacts with HC-Pro. Here we report that rgs-CaM, like HC-Pro itself, suppresses gene silencing. Our work is the first report identifying a cellular suppressor of PTGS.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anandalakshmi, R -- Marathe, R -- Ge, X -- Herr, J M Jr -- Mau, C -- Mallory, A -- Pruss, G -- Bowman, L -- Vance, V B -- New York, N.Y. -- Science. 2000 Oct 6;290(5489):142-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Sciences, University of South Carolina, Columbia, SC 29208, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11021800" target="_blank"〉PubMed〈/a〉

    Atomic-level structure engineering of metal oxides for high-rate oxygen intercalation pseudocapacitance (2018)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2018
    Description: 〈p〉Atomic-level structure engineering can substantially change the chemical and physical properties of materials. However, the effects of structure engineering on the capacitive properties of electrode materials at the atomic scale are poorly understood. Fast transport of ions and electrons to all active sites of electrode materials remains a grand challenge. Here, we report the radical modification of the pseudocapacitive properties of an oxide material, Zn〈sub〉〈i〉x〈/i〉〈/sub〉Co〈sub〉1–〈i〉x〈/i〉〈/sub〉O, via atomic-level structure engineering, which changes its dominant charge storage mechanism from surface redox reactions to ion intercalation into bulk material. Fast ion and electron transports are simultaneously achieved in this mixed oxide, increasing its capacity almost to the theoretical limit. The resultant Zn〈sub〉〈i〉x〈/i〉〈/sub〉Co〈sub〉1–〈i〉x〈/i〉〈/sub〉O exhibits high-rate performance with capacitance up to 450 F g〈sup〉–1〈/sup〉 at a scan rate of 1 V s〈sup〉–1〈/sup〉, competing with the state-of-the-art transition metal carbides. A symmetric device assembled with Zn〈sub〉〈i〉x〈/i〉〈/sub〉Co〈sub〉1–〈i〉x〈/i〉〈/sub〉O achieves an energy density of 67.3 watt-hour kg〈sup〉–1〈/sup〉 at a power density of 1.67 kW kg〈sup〉–1〈/sup〉, which is the highest value ever reported for symmetric pseudocapacitors. Our finding suggests that the rational design of electrode materials at the atomic scale opens a new opportunity for achieving high power/energy density electrode materials for advanced energy storage devices.〈/p〉

    Genetic uniformity of Alternanthera philoxeroides in South China (2003)
    Oxford, UK : Blackwell Science Ltd
    Weed research 43 (2003), S. 0 
    Details
    ISSN: 1365-3180

    Notes: Alternanthera philoxeroides (Mart.) Grisb is an invasive weed that is widespread in a variety of habitats around the world. It was introduced into China in the 1930s, and today occurs in 20 provinces. The level and pattern of genetic diversity of 193 individuals from 11 land-grown A. philoxeroides populations from South China were determined using 81 intersimple sequence repeat markers. Mean Nei's gene diversity (HE) was 0.0203 ± 0.008, and total diversity (HT) was 0.0286, indicating that genetic diversity in A. philoxeroides in South China is very low. There was a greater proportion of diversity within populations than among (GST =  0.292) populations. Gene flow (Nm) among populations was 0.607. These results are in accordance with the assumption that populations in South China are genetically depauperate because of the short introduction history and the partially clonal propagation of this weed.

    Notes: The traits of elongation, volume expansion, and water absorption are very important in determining the quality of cooked rice grains. In this study, quantitative trait loci (QTL) analysis of these traits was performed using a recombinant inbred population derived from a cross between two indica cultivars, ‘Zhenshan 97’ and ‘Minghui 63,’ which are the parents of the most widely grown hybrid rice in China. Using a linkage map based on 221 molecular marker loci covering a total of 1796 cM, a total of 33 QTLs were identified for the nine traits tested. QTLs were detected on chromosomes 1–3, 5–9, and 11, respectively. The QTLs identified included three for cooked rice grain length elongation (chromosomes 2, 6, and 11), six for width expansion (chromosomes 1-3, 6, 9, and 11) and two for water absorption (chromosomes 2 and 6). Interestingly, a single QTL located near the wx gene on chromosome 6 seemed to influence all the traits tested for the cooked rice quality.

    Genetic diversity of Pueraria lobata (kudzu) and closely related taxa as revealed by inter-simple sequence repeat analysis (2005)

    Notes: Kudzu (Pueraria lobata) is a noxious weed infesting some areas of the USA. Knowledge of its genetic variation in both native and invasive areas can lead to effective biological control measures. Inter-simple sequence repeat (ISSR) variations were studied in P. lobata and its four closely related congeneric species (P. edulis, P. montana, P. phaseoloides and P. thomsoni). ISSR results allowed a clear separation of these five species. For P. lobata, 108 plants from China and USA were analysed. The samples from the US were genetically closer to Chinese P. lobata populations than to other congeneric populations. High genetic differentiation was found for P. lobata, P. montana and P. thomsoni in Chinese samples. High genetic diversity and low population differentiation was found in P. lobata samples of the US. This supports the hypothesis of multiple introductions into the USA from different sources in Japan or China, followed by subsequent gene exchange and recombination.
