    There are two gzipped VCF (variant call format) files with variant calls for barley and soybean. A total of 652,797 SNPs were identified in the barley lines, which consisted of 13 cultivars and 2 wild accessions. For soybean, 7 cultivars and 1 wild accession were used, and 586,102 SNPs were called. Whether a variant is deleterious or not was determined using SIFT (http://sift.jcvi.org/), PolyPhen2 (http://genetics.bwh.harvard.edu/pph2/), and a likelihood ratio test of sequence conservation. Raw reads are available through the SRA accession numbers in Table S1 of Kono et al. 2016. The code used for this research, BAD_Mutations, is open source and freely available at https://github.com/MorrellLAB/BAD_Mutations.SNP calls in protein coding regions were obtained from 15 barley and 8 soybean lines. Non synonymous SNPs were predicted to be deleterious or not using three approaches.USDA NIFA National Needs Fellowship (Appropriation No. 5430-21000-006-00D)MnDrive 2014 Food Security FellowshipMinnesota Agricultural Experiment Station Variety Development fundUnited Soybean BoardU.S. NSF Plant Genome Program (BDI-1339393)Kono, Thomas J Y; Fu, Fengli; Mohammadi, Mohsen; Hoffman, Paul J; Liu, Chaochih; Stupar, Robert M; Smith, Kevin P; Tiffin, Peter; Fay, Justin C; Morrell, Peter L.

    Viscosity of alkaline basalts at high pressure: constraints on the pre-eruptive system of Campi Flegrei (Italy)

    No full text
    The Campi Flegrei Volcanic District (CFVD) includes the Campi Flegrei caldera, the islands of Procida and Ischia, and it is among the most dangerous volcanic systems of the world. The volcanic activity that has characterized the recent eruptive history of the CFVD includes both effusive and hydromagmatic eruptions that resulted in a variety of igneous products from alkaline basalts to trachytes. Among CFVD products, basaltic lava fragments dispersed in the hydromagmatic tuff of the Solchiaro eruption (Procida island) result to be representative of near-primary melts on the basis of their geochemical and isotopical signatures. The knowledge of the viscosity of primitive magmas at high pressure and temperature is needed to model their mobility and ascent rate. These variables allow us to predict the potential volcanic activity at surface. In this study, we investigated the viscosity and melt structure of APR16 alkaline basalt, a lava fragment of the Solchiaro eruption. The anhydrous glassy starting material was prepared at Bayerisches Geoinstitut by using a gas-mixing furnace, by melting the APR16 rock powder at 1400 °C for 15 minutes at atmospheric pressure and oxygen fugacity buffered at Nickel-Nickel Oxide level using a CO/CO2 gas mixture. Experiments were performed at pressure between 0.7 and 2.3 GPa and temperatures of 1200 °C-1700 °C using the Paris- Edinburgh press combined with synchrotron X-ray technique at beamline 16-BM-B (HPCAT) of the Advanced Photon Source (Argonne National Laboratory, Illinois, USA). Viscosity measurements were conducted with the falling sphere technique. The falling velocity of the platinum probing sphere was measured at each run by ultrafast X-ray radiography using a high-speed camera at 500 frames per second as recording rate. The viscosity was, then, calculated from the Stokes’ equation including the correction factors for the effect of the wall and the end effect (Kono et al., 2014). Structural measurements of the liquid at 1700 °C and 2.3 GPa were also performed using multi-angle (2θ angle between 3° to 35°) energy dispersive X-ray diffraction technique. Preliminary results show the viscosity increasing from 0.1 to 1 Pa·s as pressure decreases from which an increase in the polymerization during decompression can be inferred. Our results are used to constrain the mobility and ascent velocity of primitive alkaline basalts considered to be parental magmas at Campi Flegrei with important implications for the potential volcanic hazard of the area.

    We have developed a narrowband tunable injection-seeded, pulsed optical parametric oscillator/amplifier system. Using optical heterodyne and nonlinear-optical spectroscopic techniques, we measure a near Fourier transform limited output with a controllable frequency chirp of <10 MHz.K.G.H. Baldwin, M. Kono, B.

    A novel method to allow noninvasive, longitudinal imaging of the murine immune system in vivo

    No full text
    In vivo imaging has revolutionized understanding of the spatiotemporal complexity that subserves the generation of successful effector and regulatory immune responses. Until now, invasive surgery has been required for microscopic access to lymph nodes (LNs), making repeated imaging of the same animal impractical and potentially affecting lymphocyte behavior. To allow longitudinal in vivo imaging, we conceived the novel approach of transplanting LNs into the mouse ear pinna. Transplanted LNs maintain the structural and cellular organization of conventional secondary lymphoid organs. They participate in lymphocyte recirculation and exhibit the capacity to receive and respond to local antigenic challenge. The same LN could be repeatedly imaged through time without the requirement for surgical exposure, and the dynamic behavior of the cells within the transplanted LN could be characterized. Crucially, the use of blood vessels as fiducial markers also allowed precise re-registration of the same regions for longitudinal imaging. Thus, we provide the first demonstration of a method for repeated, noninvasive, in vivo imaging of lymphocyte behavior

    Crohn's disease and postoperative recurrence. The role of anastomotic configurations and the kono-s anastomosis.

    No full text
    BACKGROUND: The observation that in more than 90% of Crohn's disease patients the postoperative recurrences are located in the pre-anastomotic tract leads us to suppose that the anastomosis would play a role in the appearance of recurrences. AIM AND METHODS: To focus the role of different anastomotic configurations in the incidence of recurrences, the Authors have conducted a review of the literature of the last two decades and have revised critically their experience. RESULTS: The rate of recurrences seem to be lower in patients in whom the anastomotic configuration is such as to present a wide lumen; it seems that they are lower after stapled side-to-side anastomosis. The Kono-S anastomosis, recently introduced technique, seems to offer better results. CONCLUSIONS: The role of the various types of anastomosis remains uncertain. Further large-scale controlled trials with long term follow-up are needed

    Dispelling the Myths Behind First-author Citation Counts

    No full text
    We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more sophisticated methods
