Collective proceedings for damages in UK Competition Law. Case comment to the judgment Merricks v Mastercard [2019] EWCA Civ 674
Merricks v Mastercard [2019] is the first action under the newly developed ‘opt-out’ collective proceedings regime for aggregate damages under UK competition law to be considered by the UK Court of Appeal. It is significant for both the level of damages (£14 billion (€16 billion)) and the clarification of the legal test at the certification stage for the suitability for an aggregate award: the method for calculation of the aggregate damages and the sufficiency of evidence. The Court’s lowering of these thresholds importantly opens the door to future class actions and reasserts the importance of collective proceedings as a valuable means of redress for competition law infringements. The decision has now been appealed to the UK Supreme Court where these issues may be further clarified and resolved
Scale factor gage for fiber optics inspection device
Flexible wire device, fastened along outside of fiber bundle from viewing portion to tip, positions calibrated adjustable gage in field of view. Scale factor is determined from known magnification characteristics of fiber optics system or from graduations on gage tip
Quick release acoustic sensor holding fixture
Quick-release spring holder secures acoustic sensor to test material surface eliminating adhesive bonding to test material and achieving acoustic emission evaluation from tensile tests. Reusability of sensors reduces test cost
GRBlog: A Database for Gamma-Ray Bursts
GRBlog is an on-line database providing researchers with quick access to all
information reported in the GCN Circulars. Users of the GRBlog web site
(grad40.as.utexas.edu/grblog.php) can search the circulars and produce
afterglow light curve plots, or compile data tables. The site also offers
advanced search capabilities to aide in statistical studies or comparative
research. Most of the GCNs have already been entered into the GRBlog database,
with the remainder to follow shortly.Comment: 4 pages, 2 figures. Proceedings for the 2003 GRB Conference (Santa

Effects of fiber/matrix interactions on the properties of graphite/epoxy composites
A state-of-the-art literature review of the interactions between fibers and resin within graphite epoxy composite materials was performed. Emphasis centered on: adhesion theory; wetting characteristics of carbon fiber; load transfer mechanisms; methods to evaluate and measure interfacial bond strengths; environmental influence at the interface; and the effect of the interface/interphase on composite performance, with particular attention to impact toughness. In conjunction with the literature review, efforts were made to design experiments to study the wetting behavior of carbon fibers with various finish variants and their effect on adhesion joint strength. The properties of composites with various fiber finishes were measured and compared to the base-line properties of a control. It was shown that by tailoring the interphase properties, a 30% increase in impact toughness was achieved without loss of mechanical properties at both room and elevated temperatures
Quantitative imaging of the collective cell movements shaping an embryo
The recent development of imaging and image processing techniques, such as 4D microscopy and 3D cell tracking, enables analysis through quantification of the movement of large cell populations in vivo. These imaging approaches provide an opportunity to study embryonic morphogenesis during development from the level of cellular processes to the scale of entire organism. Image analysis reveals cell collective behaviors that shape an embryo and offers some surprising insights into the cell-cell interactions involved in concerted movements. We illustrate the power of this approach by studying the early development of Drosophila embryos
Image data processing system requirements study. Volume 2: Appendixes
Supporting information for the ERS loading study contains computer simulation loading output including printout description, and similar output representing data that include night station contacts
Image data processing system requirements study. Volume 1: Analysis
Digital image processing, image recorders, high-density digital data recorders, and data system element processing for use in an Earth Resources Survey image data processing system are studied. Loading to various ERS systems is also estimated by simulation
Zero-Temperature Structures of Atomic Metallic Hydrogen
Ab initio random structure searching with density functional theory was used
to determine the zero-temperature structures of atomic metallic hydrogen from
500 GPa to 5 TPa. Including zero point motion in the harmonic approximation, we
estimate that molecular hydrogen dissociates into a monatomic body-centered
tetragonal structure near 500 GPa (r_s = 1.225), which then remains stable to
2.5 TPa (r_s = 0.969). At higher pressures, hydrogen stabilizes in an
...ABCABC... planar structure that is remarkably similar to the ground state of
lithium, which compresses to the face-centered cubic lattice beyond 5 TPa (r_s
< 0.86). At this level of theory, our results provide a complete ab initio
description of the atomic metallic structures of hydrogen, resolving one of the
most fundamental and long outstanding issues concerning the structures of the
elements.Comment: 9 pages; 4 figure
