Challenges in biotechnology at LLNL: from genes to proteins

This effort has undertaken the task of developing a link between the genomics, DNA repair and structural biology efforts within the Biology and Biotechnology Research Program at LLNL. Through the advent of the I.M.A.G.E. (Integrated Molecular Analysis of Genomes and their Expression) Consortium, a world-wide effort to catalog the largest public collection of genes, accepted and maintained within BBRP, it is now possible to systematically express the protein complement of these to further elucidate novel gene function and structure. The work has ensued in four phases, outlined as follows: (1) Gene and System selection; (2) Protein expression and purification; (3) Structural analysis; and (4) biological integration. Proteins to be expressed have been those of high programmatic interest. This includes, in particular, proteins involved in the maintenance of genome integrity, particularly those involved in the repair of DNA damage, including ERCC1, ERCC4, XRCC2, XRCC3, XRCC9, HEX1, APN1, p53, RAD51B, RAD51C, and RAD51. Full-length cDNA cognates of selected genes were isolated, and cloned into baculovirus-based expression vectors. The baculoviral expression system for protein over-expression is now well-established in the Albala laboratory. Procedures have been successfully optimized for full-length cDNA clining into expression vectors for protein expression from recombinant constructs. This includes the …

Deep Levels in p- and n-type InGaAsN for High Efficiency Multi-Junction III-V Solar Cells

Red Teaming is an advanced form of assessment that can be used to identify weaknesses in a variety of cyber systems. it is especially beneficial when the target system is still in development when designers can readily affect improvements. This paper discusses the red team analysis process and the author's experiences applying this process to five selected Information Technology Office (ITO) projects. Some detail of the overall methodology, summary results from the five projects, and lessons learned are contained within this paper.

Jahn-Teller splitting and Zeeman effect of acceptors in diamond.

Employing the high resolution of a 5+4 tandem Fabry-Perot interferometer, we discovered that {Delta}{prime}, the Raman active electronic transition between the spin-orbit split 1s(p{sub 3/2}): {Lambda}{sub 8} and 1s(P{sub 1/2}) {Lambda}{sub 7} acceptor ground states, is a doublet for a boron impurity in diamond with a clearly resolved spacing of 0.81 {+-} 0.15 cm{sup {minus}1}. The direct observation of a Stokes/anti-Stokes pair with 0.80 {+-} 0.04 cm{sup {minus}1} shift provides a striking confirmation that the lower 1s(p{sub 3/2}): {Lambda}{sub 8} ground state has experienced a splitting due to a static Jahn-Teller distortion. The Zeeman effect of {Delta}{prime} has been investigated with a magnetic field along several crystallographic directions. Theory of the Zeeman effect, formulated in terms of the symmetry of the substitutional acceptor and the Luttinger parameters of the valence band, allows quantitative predictions of the relative intensities of the Zeeman components in full agreement with experiments. The observation of transitions within the {Lambda}{sub 8} Zeeman multiplet, i.e., the Raman-electron-paramagnetic-resonances, is yet another novel feature to emerge from the present study. The investigation has also yielded g-factors characterizing the Zeeman multiplets.

Benchmarking D and D procurement best practices at four commercial nuclear power plants.

The Department of Energy (DOE) has as two of its strategic objectives to safely accomplish the world's largest environmental clean-up of contaminated sites and the adoption of the best management practices of the private sector to achieve business-like results efficiently and effectively. An integral part of the strategic response to the challenges facing the Department has been the use of benchmarking and best practice management to facilitate identifying and implementing leading-edge thinking, practices, approaches, and solutions.
