    Role of computer modeling of plasmas in the 21st century (1999)

    Notes: For much of their history plasmas have been characterized by complex unpredictable behavior. This stemmed from their general nonlinear turbulent behavior, from the difficulties of carrying out controlled experiments, and from the limitations of theory. Recently this situation has changed quite dramatically with the phenomenal growth in the capabilities of computer modeling. Contact between predictions and experiments have been made over a broad range of problems. In the 21st century the power of modeling will continue to grow; the techniques for using the tool will grow and our ability to understand the complex results will improve. In this endeavor the most critical factor is the human factor. Humans must create the models; they must make sense of the results; they must condense the results to a simplified form that is useful to others. Given the importance of plasmas to human activities and in the universe, these advances point to important developments. © 1999 American Institute of Physics.

    Nuclear reaction rates and energy in stellar plasmas: The effect of highly damped modes : The 42nd annual meeting of the division of plasma physics of the American Physical Society and the 10th international congress on plasma physics (2001)

    Notes: The effects of the highly damped modes in the energy and reaction rates in a plasma are discussed. These modes, with wave numbers k(very-much-greater-than)kD, even being only weakly excited, with less than kBT per mode, make a significant contribution to the energy and screening in a plasma. When the de Broglie wavelength is much less than the distance of closest approach of thermal electrons, a classical analysis of the plasma can be made. It is assumed, in the classical analysis, with (h-dash-bar)→0, that the energy of the fluctuations (h-dash-bar)ω(very-much-less-than)kBT. Using the fluctuation-dissipation theorem, the spectra of fluctuations with (h-dash-bar)≠0 is appreciably decreased. The decrease is mainly for the highly damped modes at high frequencies (∼0.5–3kBT). Reaction rates are enhanced in a plasma due to the screening of the reacting ions. This is taken into account by the Salpeter factor, which assumes slow motion for the ions. The implication of including the highly damped modes (with (h-dash-bar)≠0) in the nuclear reaction rates in a plasma is discussed. Finally, the investigations presently done on these effects in particle simulations with the sheet model and the multiparticle quantum simulation code are described. © 2001 American Institute of Physics.

    Computer modeling of plasma: Past, present, and future (1995)

    Notes: Computer modeling has become a powerful tool for exploring the physics of plasmas. Early computers could handle only relatively simple models but nevertheless showed that these devices could shed a lot of light on the complex physics of plasmas. This capability has proved not only valuable to research but also is becoming an important teaching tool; modeling allows students to experience in concrete ways plasma phenomena which are otherwise presented only abstractly. Present-day plasma models combined with parallel computing provide sufficient power that numerical modeling of laboratory experiments on complex devices has become possible. Two examples of simulations are discussed in some detail: The "Beat Wave Accelerator'' and the "Numerical Tokamak.'' © 1995 American Institute of Physics.

    Spontaneous generation of toroidal currents (1994)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A loss-cone mechanism for self-generation of toroidal currents is examined in toroidal magnetic configurations with a mirror-like vertical (poloidal) field. The loss cone is found to be asymmetric with respect to the toroidal velocity. Particles that carry a negative toroidal current are better confined than those that carry a positive current, giving rise to a net toroidal current that can be sufficiently large to close magnetic surfaces. This mechanism is found to be dependent on the curvature drift of particles, indicating that a low-aspect-ratio toroidal configuration is more favorable for this type of current generation.

    On transport-driven currents (1994)

    Notes: An empirical electron viscosity is incorporated into Ohm's law to examine the effect of current diffusion on bootstrap currents. It is shown that for sufficiently large viscosity, no seed current is needed for steady state operation of tokamaks. This is expressed by the scaling law ΓR2m=4/27 where Rm is the magnetic Reynolds number and Γ is viscosity normalized to νeia2 (νei is the electron–ion collision frequency and a is the system size).

    Evidence for Reversible Tyrosine Protein Phosphorylation in the Okadaic Acid-Producing Marine Dinoflagellate Prorocentrum lima (1997)

    Notes: . The protist Prorocentrum lima, a primary producer of the tumour promoter okadaic acid, is a member of the dinoflagellate class of marine microorganisms. Herein, we have identified and characterized a protein tyrosine kinase (designated PLIK 1A) in P. lima that autophosphorylates almost exclusively on tyrosine residues. PLIK 1A was shown to have an approximate molecular mass of 38 kDa by SDS-PAGE and a native molecular mass within the range of 47–55 kDa by Superdex-75 gel filtration. Phosphoamino acid analysis of autophosphorylated PLIK 1A revealed the presence of phosphotyrosine and autophosphorylated PLJK 1A reacted with monoclonal anti-phosphotyrosine antibodies in a Western immunoblot. In addition, two protein tyrosine phosphatases were identified in P. lima that had apparent molecular masses within the ranges of 150–168 kDa and 73–82 kDa as determined by Superdex-200 gel filtration. These P. lima phosphatases, termed PLPTP-I and PLPTP-II, efficiently dephosphorylated tyrosine phosphorylated myelin basic protein. owever, only PLPTP-I was capable of dephosphorylating the tyrosine phosphorylated substrate angiotensin. Both PLPTP-I and PLPTP-II were able to dephosphorylate tyrosine autophosphorylated PLIK 1A. These data provide the first evidence for reversible tyrosine protein phosphorylation in P. lima by protein tyrosine kinases and phosphatases

    The Asian crisis and flow-of-funds analysis (2004)
    Oxford, UK : Blackwell Publishing Ltd.
    Review of income and wealth 50 (2004), S. 0

    Notes: This paper is an application of Flow-of-Funds analysis to the case of Thailand during the 1996–97 Asian crisis. It begins with a background historical sketch of the financial crisis in East Asia, emphasizing the central role of weak financial systems and foreign debt. The paper then presents a method of estimating quarterly Flow-of-Funds accounts using Thailand as an example. This simple method is available from data published by the I.M.F. for most of the countries of the world. The Thai data are then used in a Flow-of-Funds analysis of the crisis in Thailand. This analysis contrasts with the opening historical sketch in quantitatively tracing the significant financial flows and, particularly, the finances of the private sector. The paper closes by emphasizing the need for current reporting of data to facilitate such analyses.
