    Notizen: Abstract This paper presents two projects concerned with the application of natural language processing technology for improving communication between Public Administration and citizens. The first project, GIST,is concerned with automatic multilingual generation of instructional texts for form-filling. The second project, TAMIC, aims at providing an interface for interactive access to information, centered on natural language processing and supposed to be used by the clerk but with the active participation of the citizen.

    Chemical Composition and Microstructure of Plasma-Nitrided Aluminium (2000)
    Springer
    Microchimica acta 133 (2000), S. 285-288 
    Details
    ISSN: 1436-5073

    Thema: Chemie und Pharmazie
    Notizen: Abstract.  Detailed examinations were made by AES depth profiling, SEM, TEM and electron diffraction to get information about the relation between treatment conditions and the state of plasma-nitrided aluminium. The chemical composition and the elemental depth distribution were proofed to be depending on gas phase mixture, pressure and temperature during plasma treatment. The admixture of hydrogen during presputtering for surface cleaning and during nitriding results both in an improved nitriding behaviour and in a reduction of the formation of conical-shaped particles at the surface. The microstructure of the nitride layer isn’t depending on tested process conditions significantly. Surface and interface between layer and substrate are roughly in a scale of a few ten nanometers owing to sputtering effects. The main phase inside the layer is nanocrystalline AlN of the known hexagonal modification. In addition, some crystallites of remaining aluminium are present as a second phase. In contrast to nitrogen-implanted aluminium no preferred lattice orientation of the AlN phase was evident.

    Far ultraviolet imaging from the IMAGE spacecraft. 3. Spectral imaging of Lyman-α and OI 135.6 nm (2000)
    Springer
    Space science reviews 91 (2000), S. 287-318 
    Details
    ISSN: 1572-9672
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Physik
    Notizen: Abstract Two FUV Spectral imaging instruments, the Spectrographic Imager (SI) and the Geocorona Photometer (GEO) provide IMAGE with simultaneous global maps of the hydrogen (121.8 nm) and oxygen 135.6 nm components of the terrestrial aurora and with observations of the three dimensional distribution of neutral hydrogen in the magnetosphere (121.6 nm). The SI is a novel instrument type, in which spectral separation and imaging functions are independent of each other. In this instrument, two-dimensional images are produced on two detectors, and the images are spectrally filtered by a spectrograph part of the instrument. One of the two detectors images the Doppler-shifted Lyman-α while rejecting the geocoronal `cold’ Ly-α, and another detector images the OI 135.6 nm emission. The spectrograph is an all-reflective Wadsworth configuration in which a grill arrangement is used to block most of the cold, un-Doppler-shifted geocoronal emission at 121.567 nm. The SI calibration established that the upper limit of transmission at cold geocoronal Ly-α is less than 2%. The measured light collecting efficiency was 0.01 and 0.008 cm2 at 121.8 and at 135.6 nm, respectively. This is consistent with the size of the input aperture, the optical transmission, and the photocathode efficiency. The expected sensitivity is 1.8×10−2 and 1.3×10−2 counts per Rayleigh per pixel for each 5 s viewing exposure per satellite revolution (120 s). The measured spatial resolution is better than the 128×128 pixel matrix over the 15°×15° field of view in both wavelength channels. The SI detectors are photon counting devices using the cross delay line principle. In each detector a triple stack microchannel plate (MCP) amplifies the photo-electronic charge which is then deposited on a specially configured anode array. The position of the photon event is measured by digitizing the time delay between the pulses detected at each end of the anode structures. This scheme is intrinsically faster than systems that use charge division and it has a further advantage that it saturates more gradually at high count rates. The geocoronal Ly-α is measured by a three-channel photometer system (GEO) which is a separate instrument. Each photometer has a built in MgF2 lens to restrict the field of view to one degree and a ceramic electron multiplier with a KBr photocathode. One of the tubes is pointing radially outward perpendicular to the axis of satellite rotation. The optic of the other two subtend 60° with the rotation axis. These instruments take data continuously at 3 samples per second and rely on the combination of satellite rotation and orbital motion to scan the hydrogen cloud surrounding the earth. The detective efficiencies (effective quantum efficiency including windows) of the three tubes at Ly-α are between 6 and 10%.

    Expression of Dlx genes during the development of the murine dentition (2000)
    Springer
    Development genes and evolution 210 (2000), S. 270-275 
    Details
    ISSN: 1432-041X
    Schlagwort(e): Key words Dlx ; Homeobox ; Dentition ; Tooth
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Biologie
    Notizen: Abstract  The mammalian Dlx homeobox gene family has been shown to play multiple roles in tooth development, but a detailed comparison of the expression pattern of all members throughout tooth development has been lacking. We provide such an analysis for the six known murine Dlx genes. The expression patterns for these genes allow a refinement of previously proposed models for the role of Dlx genes in tooth type specification and raise the possibility of roles for subsets of these genes in tooth initiation, morphogenesis (enamel navel formation, enamel knot induction, cervical loop growth), and enamel formation. The relationship of Dlx gene expression to their genomic organization suggests coordinate regulation of linked genes at early stages but regulatory differences at later stages.

    The academic labor market for economists: 1995–96 (2000)
    Springer
    Atlantic economic journal 28 (2000), S. 164-185 
    Details
    ISSN: 1573-9678
    Quelle: Springer Online Journal Archives 1860-2000
    Thema: Wirtschaftswissenschaften
    Notizen: Abstract This paper provides a comprehensive, up-to-date picture of the job market for economists using new survey data on job search and employment experiences for a recent cohort of market participants. Several empirical facts are established about the labor market for economists based on separate surveys of job market applicants and chairs of programs advertising job openings in economics. In addition to providing descriptive statistics, this paper examines methods to reduce the costs of job search and recruiting and describes how market outcomes differ by department rank. Such information is of interest to current and future market participants, to advisors of job candidates, and to search committees.
