  • Kitabayashi Issay; Chiu Robert; Gachelin Gabriel; Yokoyama Kazushige (Oxford University Press, 1991-02-01)
    E1A, the early region 1A transcription unit of human adenovirus, exhibits multiple functions that regulate the expression of some cellular genes and promote cell growth and division. We found that E1A stimulated c-jun gene ...
  • Berg David T.; McClure Don B.; Grinnell Brian W. (Oxford University Press, 1992-10-01)
  • A Hibbert; E Biemont; M Godefroid; N Vaeck (1991-09-28)
    Atomic transition rates and f values have been calculated in the triplet and quintet systems and for some intercombination lines of neutral oxygen. Configuration interaction was included in the calculations performed with ...
  • N L S Martin; R P Bauman; D B Thompson; M Wilson; K J Ross (1996-10-14)
    Existing e, 2e angular distribution measurements and e, 2e energy spectra in atomic cadmium are reviewed and a major difference in the analyses of the two data sets is highlighted. It is shown that an autoionizing level, ...
  • A Dorn; A Elliott; X Guo; J Hurn; J Lower; S Mazevet; I E McCarthy; Y Shen; E Weigold (1997-09-28)
    We present measurements of the (e, 2e) cross sections of xenon for transitions leading to the and states of the residual ion using an incident polarized electron beam in coplanar asymmetric kinematics and in the intermediate ...
  • X Zhang; C T Whelan; H R J Walters (1990-09-14)
    Distorted-wave Born approximation (DWBA) calculations are reported for coplanar symmetric ionization of He(1s2) at energies of 100, 150 and 200 eV. Comparison is made with experimental data and good agreement is found ...
  • J Hanssen; B Joulakian; C D Cappello; H Hafid (1994-08-14)
    The differential cross section of the ionization of hydrogen in its n=2 degenerate state by electron impact is investigated theoretically by applying the correlated double continuum wavefunction satisfying the exact ...
  • V V Balashov; S E Martin; A Crowe (1996-04-28)
    We consider the possibility of treating (e, 2e) experiments in the region of autoionizing resonances as `perfect experiments' in which parameters relating to the direct and resonance ionization amplitudes can be determined. ...
  • llham Taouil; Alain Duguet; Azzedine Lahmam-Bennani; Birgit Lohmann; Jens Rasch; Colm T Whelan; H R James Walters (1999-01-14)
    Experimental results are presented for (e, 2e) ionization of the Ar(2p) orbital in a highly asymmetric geometry. Despite the magnitude of the momentum transfer being only 0.5 au, it is found that the triple differential ...
  • Shaun Lucey; Colm T Whelan; R J Allan; H R J Walters (1996-07-14)
    For the first time theoretical predictions for (e, 2e) on a hydrogen minus, , target are presented. This study shows that the size and shape of the TDCS for this process is extremely sensitive to the form of the approximation ...
  • S Keller; E Engel; H Ast; R M Dreizler (1997-10-28)
    The potential of applying (e, 2e) spectroscopy to metallic clusters is discussed within the jellium model. It is shown that such experiments would allow the investigation of the analogy between cluster and nuclear structure. ...

    In the established model of mammalian cell cycle control, the retinoblastoma protein (Rb) functions to restrict cells from entering S phase by binding and sequestering E2f activators (E2f1, E2f2 and E2f3), which are ...
  • Morris Erick J.; Ji Jun-Yuan; Yang Fajun; Di Stefano Luisa; Herr Anabel; Moon Nam-Sung; Kwon Eun-Jeong; Haigis Kevin M.; Näär Anders M.; Dyson Nicholas J. (Macmillan Publishers Limited. All rights reserved, 2008-09-01)
    The E2F1 transcription factor can promote proliferation or apoptosis when activated, and is a key downstream target of the retinoblastoma tumour suppressor protein (pRB). Here we show that E2F1 is a potent and specific ...
  • Coleman Robert F.; Gouvêa Fernando Q.; Jochnowitz Naomi (Hindawi Publishing Corporation, 1995)
  • A Lahman-Bennani; A Duguet; A M Grisogono; M Lecas (1992-06-28)
    (e, 3e) angular distributions from the double ionization of krypton at approximately 5.5 keV impact energy have been measured under different kinematical conditions. The original method utilized for the absolute scale ...
  • Yu V Popov; C Dal Cappello; K Kuzakov (1996-12-14)
    Five-fold and four-fold differential cross sections for electron-impact double ionization of helium are calculated in new proposed experimental situations where the scattered electron and one of the ejected electrons have ...

    N-glycosylation of proteins in the endoplasmic reticulum (ER) has a central role in protein quality control. Here we report that N-glycan serves as a signal for degradation by the Skp1–Cullin1–Fbx2–Roc1 (SCFFbx2) ubiquitin ...
  • Lellouche Jean-paul; Quinton Patrick (Taylor & Francis Group, 1994-07-01)
    The preparation of the new six carbon multifunctionalized chiral synthon 4, useful for eicosanoid synthesis, was achieved employing the Perlin hydrolysis reaction of 3,4,6-tri-O-benzyl-D-Glucal 6 in the key step.
