The beauty of laser lines

Thesis (M.S.V.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1993.Includes bibliographical references (leaves 61-63).A line, the simplest way to express an artist's feelings or interpretation of an object, has its own emotions that an artist can employ for her purpose. Laser light, the most self-concentrated, self-sustained and directed, has its unique characteristics that no other medium can imitate. When a line and laser light are combined, the result is a knife-cut clean laser line that catches the viewers breath. Artists, who have chosen the laser as their tool, need to make laser line images more attractive than laser light itself. In other words, artists must find the beauty of laser lines. Otherwise, the tool of the work dominates the artist's work itself. In this thesis, I having already chosen the laser as my tool, tried to find the beauty of laser lines by first learning the technical aspects and the characteristics of lasers. Then I examined previous works done by other laser artists, before working with lasers myself. I designed four laser projects in order to find "the beauty of laser lines," and the details of my works will be presented in this thesis.by Sue-Mie Kim.M.S.V.S

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

To investigate the role of Lyt-2 and Thy-1 in cytolysis, we have generated, by ethyl methanesulfonate mutagenesis and selection, variants of the cloned cytolytic T lymphocyte line L3 that specifically lack either Lyt-2 or Thy-1. An analysis of these variants indicates that neither Lyt-2 nor Lyt-3 is responsible for the lethal hit, but suggests that Lyt-2 and/or Lyt-3 are required for an antigen receptor functional in cytolysis. The data also suggest that the expression of Lyt-3 on the cell surface is not independent of the expression of Lyt-2. Finally the data indicate the Thy-1 plays no role in cytolysis.6788878PMC218609

Measurement of the lepton charge asymmetry in inclusive WW production in pp collisions at s=7\sqrt{s} = 7 TeV

A measurement of the lepton charge asymmetry in inclusive pp to WX production at sqrt(s)= 7 TeV is presented based on data recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 36 inverse picobarns. This high precision measurement of the lepton charge asymmetry, performed in both the W to e nu and W to mu nu channels, provides new insights into parton distribution functions.A measurement of the lepton charge asymmetry in inclusive pp to WX production at sqrt(s)= 7 TeV is presented based on data recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 36 inverse picobarns.
