    Different biological behavior of AKR lymphoma cells from primary and metastatic tumors (1985)

    Notes: Summary AKR lymphoma cells derived from primary s.c. tumors (PT) and cells from their metastases (MT) were inoculated into recipient mice in order to compare their malignant behavior. A higher malignant potential of MT compared to PT cells was found. The results support the hypothesis that metastasis is a process of selection of cells possessing a potential to metastasize, which preexist in the primary tumor. In the model used, both the selection of ‘variants’ of malignancy and the assay of malignancy were as close as possible to natural tumor progression.

    Mobility and diffusivity for vacancy diffusion in a simple cubic edge dislocation (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 58 (1985), S. 720-722

    Notes: A model of an edge dislocation in a simple cubic crystal is constructed for a [0–10] Burgers vector where vacancy transport along the edge of the extra half plane of ions is considered. The model considers a tight-binding approximation of the vacancy to the compressed region of the core and carries the calculation to the limit of an infinite length of dislocation. As a consequence the limit of the tight-binding approximation becomes exact. Previous comparison of the model with a loosely bound model illustrated the applicability of the tight-binding approximation in all circumstances. Therefore, the model is believed to quite reasonably represent the physical situation. The results of consequence include, unexpectedly, the increase without bounds of the diffusivity and effective charge for electromigration in the limit where the correlation factor becomes zero. The mobility is found to be proportional to the reciprocal of the correlation factor for all jump-frequency responses causing the unusual behavior. The diffusivity becomes large because the number of available vacancies diverges.

    Correlation factor for diffusion in an edge dislocation in a simple cubic crystal (1985)
    [S.l.] : American Institute of Physics (AIP)

    Notes: The correlation factor for diffusion is constructed for a vacancy mechanism of tracer diffusion in an edge dislocation in a simple cubic lattice. The method of calculation evaluates a weak and tight binding approximation to the problem. Comparison of the two approximations suggests that the tight binding approximation may be preferable under all circumstances.

    Mobility and diffusivity for vacancy-solute diffusion in a simple cubic edge dislocation (1985)
    [S.l.] : American Institute of Physics (AIP)
    Journal of Applied Physics 58 (1985), S. 3430-3433 
    Details
    ISSN: 1089-7550
    Source: AIP Digital Archive
    Topics: Physics
    Notes: An edge dislocation in a simple cubic crystal is considered as the basis for a model for vacancy-induced transport. The Burgers vector for the dislocation is [01¯0], and a solute atom moves along the compressed region of the core by vacancy exchanges along the edge of the extra half plane of atoms. The length of the dislocation is carried to the limit of an infinite number of lattice sites. Consequently, when the vacancy is tightly bound to the dislocation, that limit of tight binding becomes exact. In the tight binding limit, the correlation factor goes to zero for self-diffusion as expected. With vacancy solute tight binding, this result is not altered. Vacancy-solute repulsion can override vacancy-dislocation attraction and change the limit. In the case of dislocation and solute binding to the vacancy, the diffusivity becomes indefinitely large due to the abundance of defects increasing the jump frequency at a rate faster than the correlation factor decreases it. The mobility for electromigration also shows unusual limits. When the solute and dislocation both bind the vacancy, the ratio of the mobility to diffusivity becomes indefinitely large. So long as there is large dislocation vacancy binding, the ratio remains large even with solute vacancy repulsion.

    Systems model for pupil size effect (1985)

    Notes: Abstract The human pupillary control system has been the subject of interest to biologists and engineers as an example of a sensorimotor reflex which can be embedded in a control system paradigm. We present a nonlinear feedback model whose compact structure allows us to hypothesize possible physiological mechanisms which generate the proper behavior of the pupil system. The important pupil responses, including pupil size effect, asymmetry, and response to high-frequency stimuli, are defined. This model was simulated on a digital computer and comparisons to the paradigm experimental responses were performed, demonstrating a fit to each of the observed conditions. Improvements on previous models are discussed.

    Notes: Abstract Litetimes of six individual rotational levels in theν=0 vibrational level of the3 π g state of C2 were measured by monitoring the fluorescent decay after pulsed laser excitation. A value of 92±5 ns was obtained, 25% lower than previous measurements. The corresponding oscillator strength for the Swan (0-0) band isf 00=0.032±0.002, in agreement with recent theoretical work.
