    Notes: Abstract This note reports on the noise of CMOS devices. It is shown experimentally that a weak boron threshold implant (∼1012 cm−3) can influence the 1/f noise levels. For wafers with threshold adjustment the p-channel noise decreases whilst the n-channel noise increases. The changes in the n/p noise ratio with/without threshold implantation are predicted using a simple model in conjunction with carrier profile simulations.

    Syzygies among elementary string interactions in 2+1 dimensions (1991)

    Notes: Abstract The elementary string interactions are the Reidemeister moves, birth/death, and fusion/fission. Such interactions have as their trace generically mapped surfaces, and these combine to form knotted surfaces in 4-space. The syzygies among these interactions are moves to such surfaces analogous to the Reidemeister moves for knots. ‘Movie’ parametrizations of these syzygies are given and interpreted in dimension 2+2. A Morse theoretic argument shows there are 15 such movie moves. These moves, with appropriate choices of crossing information, are sufficient to construct any isotopy of an embedded surface on which a height function has been specified. The first seven of the movie moves are parametrized versions of those given by Roseman. The remaining eight are moves of Δ-type. Amplitudes assigned to these interactions must satisfy relations that correspond to the movie moves. One such relation is a Zamolodchikov tetrahedral equation. We present some puzzles about the matrix formulations of these amplitudes.

    Determination of δ13C values of sedimentary straight chain and cyclic alcohols by gas chromatography/isotope ratio mass spectrometry (1991)
    Chichester : Wiley-Blackwell

    Notes: Improved measurement of δ13C values of n-alcohols and sterols by gas chromatography/isotope ratio mass spectrometry is shown after their derivatization to silyl ethers. A method of correcting for the effects of the added silyl carbon atoms on the measurements of the silylated derivatives is also described and an application of the method for providing information on the sources of lacustrine n-alcohols and sterols is given.
