      This study presents new ignition delay data measured in a rapid compression machine over a wide range temperature, pressure and fuel/air ratio. This data is an extension of that measured previously (D. Darcy, C.J. Tobin, ...
    • High-resolution analysis of parent-of-origin allelic expression in the Arabidopsis endosperm. 

      Donoghue, Mark T. A.; Spillane, Charles (2011)
      Genomic imprinting is an epigenetic phenomenon leading to parent-of-origin specific differential expression of maternally and paternally inherited alleles. In plants, genomic imprinting has mainly been observed in the ...
    • A high-speed bi-polar outflow from the archetypical pulsating star Mira A 

      Redman, Matt P. (2009)
      Optical images and high-dispersion spectra have been obtained of the ejected material surrounding the pulsating AGB star Mira A. The two streams of knots on either side of the star, found in far ultra-viollet (FUV) GALEX ...
    • High-time Resolution Astrophysics and Pulsars 

      Shearer, Andrew (2008)
      The discovery of pulsars in 1968 heralded an era where the temporal characteristics of detectors had to be reassessed. Up to this point detector integration times would normally be measured in minutes rather seconds and ...
    • Higher torsion in the Abelianization of the full Bianchi groups 

      Rahm, Alexander D. (Cambridge University Press (Cambridge Journals Online), 2013-09)
      Denote by Q(root-m), with m a square-free positive integer, an imaginary quadratic number field, and by O-m its ring of integers. The Bianchi groups are the groups SL2(O-m). In the literature, so far there have been no ...
    • Highlight Talk: Recent Results from VERITAS 

      Lang, Mark; Gillanders, Gary (2009)
      VERITAS is a state-of-the-art ground-based gamma-ray observatory that operates in the very high-energy (VHE) region of 100 GeV to 50 TeV. The observatory consists of an array of four 12m-diameter imaging atmospheric Cherenkov ...
    • Homo- and Heterometallic planes, chains and cubanes.
