    Notes: The findings of this survey indicate that in fostering international transfer of technology much can be done to influence the development of inter-personal and inter-organizational contacts. This is not in itself a complete answer to international technology transfer, but this study suggests that it is an important, though much neglected area, which should be a central concern in science policy.A survey was conducted in 1970 and 1971 of the communication patterns of more than 1,200 research and development scientists and engineers working in Ireland. Techniques previously used in studying individual firms were adapted to suit the conditions within the country.

    Notes: We employ the entire experimentally determined protein structure for the KcsA potassium channel from Streptomyces lividans in molecular dynamics calculations to observe hydrated channel protein structure, ion solvation, selectivity, multiple ion configurations, and diffusion. Free energy perturbation calculations display a significant ion discrimination of ∼9 kT in favor of the larger K+ ion. The protein forming the channel is very flexible yet is unable to fully solvate the Na+ ion because of its smaller size and large solvation energy. There is evidence that acidic and basic sidechains may dissociate in the presence of multiple K+ ions to explain experimental ion density maps. K+ diffusion is found to vary from approximately 10%–90% of bulk, supporting the high channel currents observed experimentally. © 2000 American Institute of Physics.

    Notes: The free-surface effect on two-dimensional flow structures, especially on the trailing vortices, is investigated numerically in this paper. The solution procedure employs a higher-order semi-implicit projection method. The numerical results have been compared with experimental data on wave elevation disturbed by a submerged translating hydrofoil with a positive angle of attack. The schematic computations reveal some interesting and unique characteristics of the trailing-vortex development in a laminar flow beneath a free surface. Based on the computational data, an empirical Strouhal–Reynolds–Froude number relationship is proposed for the purely laminar vortex shedding in a free-surface flow. Moreover, the numerical findings also indicate that the presence of a free surface accelerates the Strouhal vortex frequency, yet delays not only the onset of a large-scale Kármán instability but also the occurrence of transitional behaviors. The shedding frequency downshifts drastically or even becomes discontinuous when the secondary vortex grows on the suction side. A metastable transition frequency emerges at the same time and becomes distinct with increasing Reynolds number. The variation of the vortex-shedding Strouhal number with respect to both Reynolds and Froude numbers is obtained. The power spectra of the trailing wake consist of harmonics of the vortex-shedding and transition frequencies (mfs,nft), as well as their combinations (mfs±nft). © 2002 American Institute of Physics.

    Notes: A new inner product is developed based on the Fourier analysis to study the scattering of surface waves by a floating semi-infinite elastic plate in a two-dimensional water domain of finite depth. The eigenfunctions for the plate-covered region are orthogonal with respect to this new inner product. The problem is studied for various wave and geometrical conditions. Especially, the influence of different edge conditions on the hydrodynamic behavior is investigated and compared. The edge conditions considered in the present study involve (i) a free edge, (ii) a simply supported edge, and (iii) a built-in edge. The hydrodynamic performance of an elastic plate is characterized for various conditions in terms of wave reflection and transmission, plate deflection, and surface strain. It is observed that the hydrodynamic behavior depends on the wave conditions, the geometrical settings, and the edge conditions. The built-in edge condition induces the maximum wave reflection and the minimum wave transmission. The free edge condition leads to the maximum plate deflection. © 2001 American Institute of Physics.

    Notes: Listener responses (LRs) have been found to appear far less frequently among children than among adolescents and adults, and the initial explorations of this finding, both empirical and theoretical, are reported in this paper. Observations of children in first, third, and fifth grade in school (but not in school-like situations) showed LRs to be almost absent except under the strongest social “pull,” and to be very variable from child to child. Video taped sessions in the laboratory showed older children to make small movements which may not be communicative, to make the more definite ones a bit late compared with adults, and confirmed the wide individual variability. Discussion focuses on two functions of LRs, the linguistic and the social.
