    Influence of gene dosage and autoregulation of the regulatory genes INO2 and INO4 on inositol/choline-repressible gene transcription in the yeast Saccharomyces cerevisiae (1997)

    Notes: Abstract Expression of structural genes of phospholipid biosynthesis in yeast is mediated by the inositol/choline-responsive element (ICRE). ICRE-dependent gene activation, requiring the regulatory genes INO2 and INO4, is repressed in the presence of the phospholipid precursors inositol and choline. INO2 and, to a less extent, INO4 are positively autoregulated by functional ICRE sequences in the respective upstream regions. However, an INO2 allele devoid of its ICRE functionally complemented an ino2 mutation and completely restored inositol/choline regulation of Ino2p-dependent reporter genes. Low-level expression of INO2 and INO4 genes, each under control of the heterologous MET25 promoter, did not alter the regulatory pattern of target genes. Thus, upstream regions of INO2 and INO4 are not crucial for transcriptional control of ICRE-dependent genes by inositol and choline. Interestingly, over-expression of INO2, but not of INO4, counteracted repression by phospholipid precursors. Possibly, a functional antagonism between INO2 and a negative regulator is the key event responsible for repression or de-repression.

    Notes: Tape ball grid array (TBGA) packages offer many of theadvantages of plastic BGAs, namely excellent durability, improved board space utilisation and ease ofsurface mount assembly along with the associated yield improvements. TBGA packages go a stepfurther, however, and offer the added benefits of improved signal integrity, better heat dissipation, andextendability to higher pin counts. This paper outlines the design and material selection process toproduce a low-cost TBGA which allows the wire bonding of a die. This type of packageoffers an attractive solution for applications requiring mid to high I/O capability and good electricaland thermal properties. Preliminary results have demonstrated the feasibility of wire bonding to thispackage at temperatures up to 200°C.

    Fabrication of large periodic arrays of AlGaAs microdisks by laser-interference lithography and selective etching (2002)
    Woodbury, NY : American Institute of Physics (AIP)

    Notes: By laser-interference lithography, reactive-ion etching, and selective wet-chemical etching using a citric acid-based solution, we have fabricated large periodic arrays of AlGaAs microdisks with periods of 4 μm and disk diameters between 1.5 and 2 μm. The arrays are characterized by temperature-dependent photoluminescence spectroscopy. Taking into account the below-threshold absorption of the quantum wells inside the disks, we get disk quality factors close to the theoretical maximum value. We demonstrate that our technique allows one also to produce one-dimensionally or two-dimensionally coupled arrays of microdisks. © 2002 American Institute of Physics.

    Involvement of MAP-kinases and -phosphatases in uptake and intracellular replication of Listeria monocytogenes in J774 macrophage cells (1997)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 157 (1997), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: In this study we show that protein tyrosine kinases and also protein tyrosine phosphatases are involved in the uptake of Listeria monocytogenes by J774 macrophages to a different extent than in the uptake of inert latex beads. In addition, protein tyrosine kinases are necessary for the intracellular growth and survival of L. monocytogenes. The expression of the MAP kinase phosphatase MKP-1, a protein tyrosine phosphatase, is induced upon infection, and phagocytosis of L. monocytogenes by J774 cells overexpressing the MKP-1 protein is reduced compared to control cells. The decreased phagocytosis of L. monocytogenes as a result of the MKP-1 overexpression in J774 macrophages suggests that the activation of the MAP kinase(s) ERK-1 and/or ERK-2 is an essential requirement for the uptake of L. monocytogenes by J774 macrophages.

    Dynamics of hydrogen-bonded liquids confined to mesopores: A dielectric and neutron spectroscopy study (1995)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 103 (1995), S. 2016-2024

    Notes: In this paper we present and discuss experimental results on molecular mobility in propylene glycol and its three oligomers confined to the ∼100 A(ring) pores of a controlled porous glass. The objective is to elucidate the finite size effects on the dynamics of hydrogen-bonded liquids of different molecular weights but identical chemical composition. The methods of dielectric and neutron spectroscopy have been employed to investigate both the low- and high-frequency features as a function of temperature. We find that all fluids in pores separate into two distinct liquid phases. (i) molecules physisorbed at the surface which exhibit a dramatic frustration of their mobility related to a substantial positive shift of the glass transition temperature Tg by up to ΔTg≈+47 K; and (ii) relatively "free'' molecules in the inner pore space subject to only moderate retardation of the α and normal mode relaxation and substantial broadening of the distribution of relaxation times. The shift in Tg for the α process with ΔTg≈+5 K is maximal for the monomer liquid and gradually diminishes with increasing molecular weight or decreasing intermolecular hydrogen bonding. The inelastic neutron spectrum of confined propylene glycol shows the boson peak as expected in bulk strong and intermediate glass formers in the vicinity of Tg. This effect can be attributed to the finite-size induced crossover from long wave vibrations characteristic of a continuous medium to localized vibrations in a confined geometry. © 1995 American Institute of Physics.

    High resolution temperature and density profiles during the energy quench of density limit disruptions in Rijnhuizen tokamak project (2002)
    [S.l.] : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Measurements of the electron temperature, Te, and density, ne, during the energy quench of a major disruption showed that the onset of Te erosion in the neighborhood of the m/n=2/1 O point at the low field side (LFS) accelerates the well-known m/n=1/1 erosion of the core temperature. During this phase Te(r) is only partially flat in the region between the q=2 and the q=1 surfaces and ne(r) decreases in the core and increases inside the m/n=2/1 island. Immediately after the flattening of Te(r) a large peak in Te and to a lesser extent in ne has been observed. This peak is radially localized at the q=2 radius at the LFS, is very short lived and is poloidally asymmetric. Te profiles measured by the heterodyne radiometer and the Thomson scattering agree very well up to the time Te(r) flattens but afterwards can be a factor of two different. © 2002 American Institute of Physics.

    The electron cyclotron absorption diagnostic at the Rijnhuizen tokamak project (1997)
    [S.l.] : American Institute of Physics (AIP)
    Review of Scientific Instruments 68 (1997), S. 4439-4447

    Notes: A new 20-channel electron cyclotron absorption diagnostic has been developed at the Rijnhuizen tokamak project. It is the first time the electron pressure profile in a tokamak plasma can be measured directly with a time resolution of 1 ms. The diagnostic measures simultaneously the emission and absorption of the second harmonic electron cyclotron frequencies. Microwaves are injected from the high field side and detected at the low field side in the equatorial midplane. The transmitted power is measured after a single pass through the plasma column. The absorption measurements are complicated by nonresonant losses: refraction of the injected microwaves (losses up to 100%), and scattering of microwaves by density fluctuations (losses 2%–3%). A fast algorithm has been developed to obtain a quantitative measure for these nonresonant losses. This calculation method is based on a parametrization of the experimental data. Combining the electron cyclotron absorption (ECA) measurements and the parametrization provides a reliable tool for determining the optical depth, the electron temperature, and the electron pressure. A good agreement was found between pressure and temperature profiles, measured with ECA and other diagnostics. © 1997 American Institute of Physics.
