    Kinetics of the formation of space-charge field in photorefractive polymers (2000)

    Notes: We derive a kinetic differential equation for the formation of space-charge field (SCF) in photorefractive polymers and give its general solution, which is based on Schildkraut's work. It is found that SCF consists of two exponential decay waves and there are two decay factors corresponding to two response time constants of SCF. Changing the parameters in the solution, we can understand the formation of SCF for different cases. In this article, we discuss a case of no traps and find that both static and transient actions of SCF are determined by the grating wave vector k and total incident intensity Ii. © 2000 American Institute of Physics.

    Theory of space-charge field with a moving fringe in photorefractive polymers (2001)

    Notes: Resonance of space-charge field can occur in photorefractive polymers through a moving fringe and can be described by a forced oscillation equation with damping. The resonance frequency and the magnitudes of both the amplitude and the imaginary part of the space-charge field at the resonance frequency are functions of three experimental parameters: total incident intensity, applied electric field, and grating wave vector. Thus, the diffraction efficiency of grating and the gain coefficient of two-wave mixing are dependent on the three experimental parameters. Our theory can also be applied to inorganic photorefractive crystals. © 2001 American Institute of Physics.

    Holographic fabrication of multiple layers of grating inside soda–lime glass with femtosecond laser pulses (2002)

    Notes: Gratings have been holographically fabricated inside soda–lime glass by two-beam interference of a single 130 fs laser pulse at a wavelength of 800 nm. Because the grating was localized in the focal volume and the depth at which the grating was formed can be controlled by translation of the sample, multiple layers of grating can be fabricated. As an example, three layers of grating have been recorded at depths of ∼200, ∼400, and ∼600 μm, respectively. These gratings can be read by either of the two recording beams with reduced energy, which demonstrates their potential applications in integrated optics and optical storage. © 2002 American Institute of Physics.

    The power law relation of spiral waves in the Belousov–Zhabotinsky reaction (2000)

    Notes: The relationship of the period Ts and the wavelength λs of spiral waves with the control parameters is systematically studied with the Belousov–Zhabotinksy (BZ) reaction in a spatially extended quasi-two-dimensional system. Our experiments indicate that Ts and λs not only rely on the concentrations of sulfuric acid and sodium bromate, as indicated in the previous work [A. L. Belmonte, Q. Ouyang, and J. M. Flesselles, J. Phys. II 7, 1425 (1997)] but also have strong relation with the concentration of malonic acid (MA). With the influence of the concentration of MA taken into consideration, a revised power law of spiral waves is suggested, which is qualitatively in agreement with early works of numerical simulations and theoretical analysis. © 2000 American Institute of Physics.

    Ab initio configuration interaction study of the predissociation of the (4s), (4pσ) 1,3Π, and (4pπ) 3Σ+ Rydberg states of HCl and DCl (2000)

    Notes: Ab initio configuration interaction (Cl) calculations are carried out for the lowest-lying six 1,3Π and three 3Σ+ states. In addition, the first and second radial couplings 〈φi(R,r)|∂/∂R|φj(R,r)〉 and 〈φi(R,r)|∂2/∂R2|φj(R,r)〉, spin-orbit, and rotational couplings are also evaluated based on the resulting highly correlated wave functions. Energy positions and predissociation linewidths of rovibrational levels associated with the above electronic states are determined in the adiabatic representation by means of the complex scaling method employing a basis of complex scaled Hermite polynomials and Gauss–Hermite quadrature. The present treatment correctly reproduces a number of observed trends in energy and line broadening for individual rovibrational levels of the (4s)b 3Π and C 1Π states of HCl and DCl. The calculated linewidths for the v=0, J=2, and J=8 rovibrational levels of the (4s)C 1Π state of HCl are 1.2 and 2.1 cm−1, respectively, which is in good agreement with the recently observed rotational dependence of line broadening for the v=0 level of this state [M. H. Alexander et al., Chem. Phys. 231, 331 (1998)]. The present calculations find that the linewidths of the (4pσ)D 1Π state are greater than for the (4pσ)d 3Π state. The distinctive predissociation mechanisms of the D 1Π and the d 3Π states are discussed on the basis of the calculated radial couplings. The calculations predict very broad lines for the v=0 and 1 vibrational levels of the lowest adiabatic bound 3Σ+ state, consistent with the fact that the corresponding state has not yet been identified by spectroscopic means. © 2000 American Institute of Physics.

    On the independence of nonadiabatic coupling elements on the choice of origin of the coordinate system (2000)

    Notes: A finite-difference approach is employed to demonstrate the manner in which the values of nonadiabatic radial coupling matrix elements vary with the choice of origin of the nuclear coordinate system. Configuration interaction (CI) calculations for a series of excited states of the HCl molecule verify that such results do not depend on the location of the center of mass XCM as long as it is held fixed during the differentiation process. The reason that radial coupling matrix elements are found to vary with the choice of origin of the coordinate system in standard scattering formulations is that the corresponding motion is not purely internal but rather has a definite translational component, namely a linear dependence of XCM on the bond distance R is assumed. An identity which relates variations of such (mixed internal-translational motion) nonadiabatic coupling elements to the value of the electric dipole transition moment when the latter prescription is employed for choosing the origin of the nuclear coordinate system is also verified by the present CI calculations. © 2000 American Institute of Physics.

    Nonadiabatic effects in the lowest 0+(3P) ion-pair states of CIF (2001)

    Notes: Nonadiabatic calculations of vibrational energies and wave functions are carried out for the E(0+, 3P2) and f(0+, 3P0) ion-pair states of the ClF molecule. It is shown that strong radial coupling between these 0+ states is caused by a significant variation of their 3Σ− and 3Π Λ-S contributions with internuclear distance and results in vibrational energy shifts as well as changes in the corresponding adiabatic vibrational wave functions. Both resonance and nonresonance interactions between vibronic levels of these two adiabatic states are found to be important, but significant mixing of the adiabatic wave functions can occur only for the nearly resonant levels located around f,v=3; E,v=7 and f,v=8; E,v=13. Nonadiabatic interactions are found to be responsible for the appearance of long-wavelength maxima in the f,v=3,4 emission spectra that was the subject of the discrepancy between theoretical and experimental data discussed in the previous paper [A. B. Alekseyev, H.-P. Liebermann, R. J. Buenker, and D. B. Kokh, J. Chem. Phys. 112, 2274 (2000)]. Inclusion of nonadiabatic effects leads to notably better agreement between the calculated and measured bound-free emission spectra. © 2001 American Institute of Physics.

    Ab initio calculation of predissociation linewidths in the Schumann–Runge bands of the oxygen molecule (2001)

    Notes: Ab initio multireference single- and double-excitation configuration interaction calculations have been carried out for potential curves of the B 3Σu−, 1Πu, 3Πu, 5Πu, and 3Σu+ electronic states of the O2 molecule. Spin-orbit interaction matrix elements among the above states and rotational interaction matrix elements between the B 3Σu− and the 3Πu states have been evaluated in order to investigate the observed line broadening in the Schumann–Runge bands. Predissociation linewidths of rovibrational levels of the B 3Σu− state are determined by using the complex rotation method in conjunction with the Gauss–Hermite quadrature procedure. It has been found that the 5Πu and 3Πu states play dominant roles in the predissociation of the B 3Σu− state. The calculated linewidths for rovibrational levels of v=0–13, N=0–36 of the F2 fine-structure components of the B 3Σu− state are in very good agreement with experimental results. Isotopic effects in the predissociation of the B 3Σu− state are studied by means of calculations for 18O2 and 16O18O and the theoretical results are found to be in good agreement with the observed average predissociation linewidths in each case. © 2001 American Institute of Physics.

    Differentiation of Trypanosoma brucei may be stage non-specific and does not require progression of cell cycle (2003)

    Notes: Ubiquitination and proteasomal degradation of cell cycle regulatory proteins are known to play a pivotal role in controlling the progression of the eukaryotic cell cycle. Using the technique of RNA interference (RNAi) on the bloodstream form of Trypanosoma brucei, we were able to knock down expression of each of the 11 non-ATPase regulatory subunit proteins (Rpns) in the 19S regulatory complex of the 26S proteasome. In each case, the knock-down led to arrest of cells within the G1 and G2 phases, suggesting blockage of cell cycle progression at both G1/S and G2/M boundaries. This finding differs from that observed previously in the procyclic form of T. brucei, in which loss of individual Rpns blocks only passage across the G2/M boundary. Thus, proteasomal degradation of additional regulatory protein(s) may be required for exiting from G1 phase in the bloodstream form. In vitro differentiation of each of the 11 Rpn-depleted bloodstream form cell lines into the procyclic form was monitored. Each cell line proceeded to completion of the differentiation process like the wild-type cells with the total percentage of differentiated cells about equivalent to the sum of G1 and G2 cells. Thus, cells trapped in either G1 or G2 phase can apparently still enter and complete the process of differentiation, which is probably neither stage specific nor dependent on the progression of the T. brucei cell cycle. The process is probably a simple pattern change of gene expression in the trypanosome induced by a temperature decrease from 37°C to 26°C in the presence of citrate and cis-aconitate.
