A swarm analysis technique based on the solution of the Boltzmann equation is used to derive low energy electron collision cross sections for tetramethylsilane （TMS）. The calculated swarm parameters with this first available cross sections set is consistent with measured values of the swarm parameters. Calculations of transport parameters in mixtures of TMS with argon are also presented.

We present quantum mechanical vibrational computations beyond the harmonic approximation from effective second order perturbative and variation perturbation treatments defined as static approaches, as well as vibrational analysis from density functional theory molecular dynamics trajectories at 300 and 600 K. The four schemes are compared in terms of prediction of fundamental transitions, and simulation of the corresponding medium infrared spectrum at the same level of theory using the B3LYP/6-31＋G（d,p） description of the electronic structure. We summarize conclusions about advantages and drawbacks of these two approaches and report the main results obtained for semi-rigid and flexible molecules.

We study further the method of concatenating the outputs of two functions for designing an APN or a differentially 4-uniform (n, n)-function for every even n. We deduce several specific constructions of APN or differentially 4-uniform (n, n)-functions from APN and differentially 4-uniform (n/2, n/2)-functions. We also give a construction of quadratic APN functions which includes as particular cases a previous construction by the author and a more recent construction by Pott and Zhou.

Wire Rope Isolators (WRI) are well known and used for theprotection of sensitive equipment against non-contact underwaterexplosions (UNDEX) on board Naval Ships, amongst others, whichare extremely destructive and can comple`tely impair the ship’scombat *** WRI exhibit a number of definite advantages, such aslarge deflection capability, modularity and insensitivity to aggressiveenvironment when proper materials are used. However, theirinherent nonlinearity does not always provide the best solution interms of shock attenuation. (Stiffening tension characteristics)Fortunately, there are ways to overcome this problem, namelyincreasing their damping and/ or changing their aspect ratio. It is thepurpose of this presentation to show how to overcome this problemand through analysis, by use of validated models of the shock testingmachines. The existing technology will be briefly presented andHDWRI (high damping wire rope isolators) vs. conventional WRIresponses will be compared on the US Navy shock testing machinesof MIL-S-901D.

Zinc finger-homeodomain proteins （ZHD） are present in many plants; however, the evolutionary history of the ZHD gene family remains largely unknown. We show here that ZHD genes are plant-specific, nearly all intronless, and related to MINI ZINC FINGER （MIF） genes that possess only the zinc finger. Phylogenetic analyses of ZHD genes from representative land plants suggest that *** plant ZHD genes occupy basal positions and angiosperm homologs form seven distinct clades. Several clades contain genes from two or more major angiosperm groups, including eudicots, monocots, magnoliids, and other basal angiosperms, indicating that several duplications occurred before the diversification of flowering plants. In addition, specific lineages have experienced more recent duplications. Unlike the ZHD genes, MIFs are found only from seed plants, possibly derived from ZHDs by loss of the homeodomain before the divergence of seed plants. Moreover, the MIF genes have also undergone relatively recent gene duplications. Finally, genome duplication might have contributed substantially to the expansion of family size in angiosperms and caused a high level of functional redundancy/overlap in these genes.
