    Ulitaprecision Machining Characteristics of Poly-Crystalline Germanium

    Get PDF
    Germanium is an excellent infrared optical material. 0n most occasions, singlecrystalline germanium is used as optical lens substrate because its homogeneous structure is beneficial for fabricating uniform optical surfaces. In this work, we attempt to use poly crystals as lens substrates instead of single crystals, which may lead to a significant reduction in production cost. We conducted ultraprecision cutting experiments on poly-crystanine germanium to examine the microscopic machinability. The crystal orientations of specific crystal grains were characterized, and the machining characteristics of these crystal grains including surface textures, cutting forces, and grain boundary steps were investigated under various machining conditions. It was possible to produce uniformly ductile-cut surfaces cross all crystal grains by using an extremely small undeformed chip thickness (~80nm)under negative tool rake angles (~-45°).This work indicates the possibility of fabricating high-quality infrared optical components from poly-crystalline germanium.journal articl

    <p>Analysis of 400 bp upstream sequence from 61 EZGs by SCOPE. A) Snapshot of SCOPE output showing the top 10 motifs identified. The top 5 are color-labeled and correspond to the motif locations in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0033933#pone-0033933-g003" target="_blank">Figure 3C</a>. Note that the highest-ranking motif TACCYVB is the complement of VBRGGTA. “Count” is the total motif occurrences on both strands, “Sig Value” is the negative log of the E value, “Coverage” is the % of sequences in the dataset that contain the motif, and “Algorithm” shows which of the three algorithms identified the motif. B) Sequence logos and PWM for VBRGGTA. C) Schematic from SCOPE output showing 400 bp upstream sequence and locations of 5 highest scoring motifs in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0033933#pone-0033933-g003" target="_blank">Fig. 3A</a>. Red blocks correspond to VBRGGTA. The gene IDs are shown to the right of each sequence with the prefix “AAEL0” omitted.</p

    <p>The percentage of intronless genes was compared between EZGs, 4–8 hr, 8–12 hr and all <i>Ae. aegypti</i> genes. P-values calculated by the Chi-squared test are shown for two comparisons. See File S2 for numbers of genes with and without introns for each group. See File S3 for transcript IDs for the 2–4, 4–8, and 8–12 hr groups.</p

    An increase in the fraction of reads substantiating the second alleles if present, and all minor alleles.

    No full text
    <p>The average fraction of reads representing A) all minor alleles (only for loci with minor alleles) and B) the second allele in both heterozygotic and homozygotic loci that have at least one minor allele, for DLD-1, PD20 and Capan-1 cells were compared to the average of the DNA repair proficient cell lines. The (<b><sup>+</sup></b>) denotes a significant difference from DNA repair proficient (p<0.01) with z-test.</p
