    cDNA sequence and chromosome localization of pig α1,3 galactosyltransferase (1995)

    Notes: Abstract Human serum contains natural antibodies (NAb), which can bind to endothelial cell surface antigens of other mammals. This is believed to be the major initiating event in the process of hyperacute rejection of pig to primate xenografts. Recent work has implicated galoctosyl α1,3 galactosyl β1,4 N-acetyl-glucosaminyl carbohydrate epitopes, on the surface of pig endothelial cells as a major target of human natural antibodies. This epitope is made by a specific galactosyltransferase (α1,3 GT) present in pigs but not in higher primates. We have now cloned and sequenced a full-length pig α1,3 GT cDNA. The predicted 371 amino acid protein sequence shares 85% and 76% identity with previously characterized cattle and mouse α1,3 GT protein sequences, respectively. By using fluorescence and isotopic in situ hybridization, the GGTA1 gene was mapped to the region q2.10–q2.11 of pig chromosome 1, providing further evidence of homology between the subterminal region of pig chromosome 1q and human chromosome 9q, which harbors the locus encoding the AB0 blood group system, as well as a human pseudogene homologous to the pig GGTA1 gene.

    Calculation of Frequency-Dependent Polarizabilities of Quasi-One-Dimensional Systems (1997)
    Springer
    Journal of molecular modeling 3 (1997), S. 182-192

    Notes: Abstract Calculations of frequency-dependent polarizabilities of quasi-one-dimensional systems are reported using the coupled Hartree-Fock method recently developed for polymers. Computations have been performed for infinite model chains of hydrogen and water molecules, respectively. The frequency dispersions applying different basis sets agree very well with theoretical results in the literature both for the chain and the respective molecule. In addition the dynamic polarizabilities of the conjugated periodic systems polyacetylene, polycarbonitrile and polyaziridine have been investigated.

    Crystal orbital calculation of coupled Hartree–Fock dynamic (hyper)polarizabilities for prototype π-conjugated polymers (2001)

    Notes: Ab initio static and dynamic (hyper)polarizability calculations at the time-dependent coupled-perturbed Hartree–Fock level have been carried out on polyyne, all-trans polyacetylene (PA), and trans-transoïd polymethineimine by a noniterative method. The dependence on basis set and on the number of neighboring unit cells exactly included has been investigated. The 6-31G basis set with nine neighboring unit cells, and long-range Coulomb interactions taken into account, was utilized in the final calculations. Although in many instances our results are the first that have been obtained we compare with oligomer calculations wherever possible. For PA the theoretical result is also compared with experiment and the main reasons for the existing discrepancy are addressed. © 2001 American Institute of Physics.

    Coupled-perturbed Hartree–Fock theory for infinite periodic systems: Calculation of static electric properties of (LiH)n, (FH)n, (H2O)n, (–CNH–)n, and (–CH=CH–)n (2001)

    Notes: Previously we have shown how to obtain the electric properties of a polymer or other periodic system at the coupled Hartree–Fock level by direct, analytical calculation rather than by extrapolation of oligomer results. Here we add computationally simpler noniterative formulas and test the methodology for the longitudinal dipole moment (μ), polarizability (α), first hyperpolarizability (β), and second hyperpolarizability (γ) of five quasilinear polymers: (LiH)n, (FH)n, (H2O)n, trans-polymethineimine (–CNH–)n, and trans-polyacetylene (–CH=CH–)n. The polymer values are in good agreement with large-oligomer calculations. In this connection the role of phase factors, particularly in determining the dipole moment, is elucidated. We are now in a good position to include electron correlation using methods analogous to those employed for molecular systems. © 2001 American Institute of Physics.

    Intangible Assets, Information Complexity, and Analysts’ Earnings Forecasts (2005)
    Oxford, UK; Malden, USA : Blackwell Publishing Ltd/Inc.
    Journal of business finance & accounting 32 (2005), S. 0

    Topics: Economics
    Notes: Abstract:  We examine the relation between analysts’ earnings forecasts and firms’ intangible assets, including technology-based intangibles, brand names, and recognized intangibles. We predict that high information complexity of intangible assets increases the difficulty for analysts to assimilate information and increases analysts’ forecast error of intangibles-intensive firms. We find a positive association between analysts’ forecast error and the firm's intangible intensity that deviates from the industry norm. We also find that analysts’ forecast errors are greater for firms with diverse and innovative technologies. In contrast, analysts’ forecast errors are smaller for biotech/pharmaceutical and medical equipment firms that are subject to intangibles-related regulation.

    Calculation of ab initio dynamic hyperpolarizabilities of polymers (1999)

    Notes: The coupled Hartree–Fock (CHF) equations in second order are derived to calculate dynamic polarizabilities and hyperpolarizabilities for infinite periodic chains. The analytical expressions for the second derivatives of the perturbed crystal orbitals with respect to the quasimomentum k are developed. The first and second derivatives are required on behalf of the definition of the perturbation operator describing the effect of the time-dependent electric field on the electronic structure of the polymer. The computer program has been applied to calculate the tensor elements of the second-harmonic generation and the optical rectification for the model chain poly(water) and the conjugated π-electron system poly(carbonitrile), respectively. The CHF-results are compared with uncoupled Hartree–Fock (UCHF) calculations. © 1999 American Institute of Physics.

    Static and dynamic polarizabilities and first hyperpolarizabilities for CH4, CF4, and CCl4 (1998)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: Complete polarizabilities and first hyperpolarizabilities (which include zero-point-vibrational averaging and other vibrational corrections) have been calculated at the self-consistent-field and Møller–Plesset second order perturbation levels of approximation for CH4, CF4, and CCl4. As well as the static values, α(−ω;ω), β(−ω;ω,0), and β(−2ω;ω,ω) have also been determined. The values of β(−2ω;ω,ω) for CCl4 are germane to a proposed standard for the determination of nonlinear optical properties in solution. For CCl4, our best estimate of β(−2ω;ω,ω) at (h-dash-bar)ω = 0.040 a.u. is 13.6 a.u., the experimentally-derived gas value at (h-dash-bar)ω = 0.043 a.u. is 20.7± 1.6 a.u. This latter value has been used to substantiate the proposed liquid phase value. © 1998 American Institute of Physics.

    Notes: CVD diamond thick film was brazed to cemmented carbide using a Ag-Cu-Ti active fillermetal. The brazing process was performed in a vacuum furnace under different processing condition.The interfacial microstructure and characterization between diamond and Ag-Cu-Ti filler metalwere studied by SEM, EPMA and EDX. The morphology and distribution of new compound areshown for the first time (Figs). Results illustrate that a small amount of new compound TiC, TiCucompound exist in the interface. TiC layer exists in the interface and it's thickness is variationalwith the varying of processing condition such as peak heating temperature, keeping time and so on.New compound TiC accretes with the surface atoms of diamond in a special section, and particularorientation relationships are occasionally observed by examining the fracture section. TiCu layernear TiC exists in the interface. It is worth notice that too much TiC and TiCu in interface couldweaken join strength because TiC and TiCu are brittle

    Notes: The structures and energies of B+13, observed experimentally to be an unusually abundant species among cationic boron clusters, have been studied systematically with B3LYP/6-31G* density functional theory. The most thermodynamically stable B+12 and B+13 clusters are confirmed to have planar or quasiplanar rather than globular structures. However, the computed dissociation energies of the 3-dimensional B+13 clusters are much closer to the experimental values than those of the planar or quasiplanar structures. Hence, planar and 3-dimensional B+13 may both exist.   © 1998 John Wiley & Sons, Inc.   J Comput Chem 19: 203-214, 1998
