    Impact ionization coefficients in strained InGaAs/InAlAs multiquantum wells (1993)

    Notes: We have measured electron and hole impact ionization coefficients in biaxially strained InxGa1−xAs/InyAl1−yAs (0.44≤x≤0.62, 0.44≤y≤0.62) multiquantum wells for the first time. It is seen that β/α is enhanced due to strain-induced changes in band gap, band offsets, and bandstructure for tensile strain in the well and compressive strain in the barrier. The results have been interpreted by considering band-to-band impact ionization and band-edge discontinuity impact ionization processes.

    Subcellular Localisation of 14-3-3 Isoforms in Rat Brain Using Specific Antibodies (1994)

    Notes: Abstract: The 14-3-3 protein family, which is present at particularly high concentrations in mammalian brain, is known to be involved in various cellular functions, including protein kinase C regulation and exocytosis. Despite the fact that most of the 14-3-3 proteins are cytosolic, a small but significant proportion of 14-3-3 in brain is tightly and selectively associated with some membranes. Using a panel of isoform-specific antisera we find that the ε, η, γ, β, and ζ isoforms are all present in purified synaptic membranes but absent from mitochondrial and myelin membranes. In addition, the η, ε, and γ isoforms but not the β and ζ isoforms are associated with isolated synaptic junctions. When different populations of synaptosomes were fractionated by a nonequilibrium Percoll gradient procedure, the ε and γ isoforms were present and the β and ζ isoforms were absent from the membranes of synaptosomes sedimenting in the more dense parts of the gradient. The finding that these proteins are associated with different populations of synaptic membranes suggests that they are selectively expressed in different classes of neurones and raises the possibility that some or all of them may influence neurotransmission by regulating exocytosis and/or phosphorylation.

    Isoform Pattern of 14-3-3 Proteins in the Cerebrospinal Fluid of Patients with Creutzfeldt-Jakob Disease (1999)

    Notes: Abstract : Two-dimensional polyacrylamide gel electrophoresis of CSF has been used in the diagnosis of Creutzfeldt-Jakob disease (CJD). One of the two diagnostic protein spots was identified as isoform(s) of the 14-3-3 family of abundant brain proteins. This has led to the development of one-dimensional 14-3-3 sodium dodecyl sulfate polyacrylamide gel electrophoresis immunoblot, which is currently used to support the diagnosis of CJD. In the present study employing western blot analysis, we have identified the panel of 14-3-3 isoforms that appear in the CSF of 10 patients with CJD compared with 10 patients with other dementias. The results clearly show that the 14-3-3 isoforms β, γ, ε, and η are present in the CSF of patients with CJD and can be used to differentiate other dementias. 14-3-3η also gave a baseline signal in all patients with other dementias, including six patients with Alzheimer's disease. The presence of 14-3-3η in the CSF of a patient with herpes simplex encephalitis was particularly noteworthy. This study has determined that isoform-specific 14-3-3 antibodies against β, γ, and ε should be considered for the neurochemical differentiation of CJD from other neurodegenerative diseases.

    Notes: We have measured the electron and hole impact ionization coefficients in Si1−xGex alloys. Carrier multiplication measurements were made on relaxed Si1−xGex/Si diodes grown by gas source molecular beam epitaxy. The hole to electron impact ionization coefficient ratio, β/α, varies from 0.3 to 4 in the composition range of x=0.08–1.0. © 1995 American Institute of Physics.

    Notes: We report the modulation characteristics of multiple quantum well tunneling injection lasers designed for 0.98 μm emission wavelength. Electrons are injected into the active region through a single barrier via tunneling. The active region has four quantum wells with different well widths. Improved high frequency performance, compared to similar separate confinement heterostructure lasers, has been demonstrated. The modulation response at 21 GHz is above 0 dB and the extrapolated −3 dB modulation bandwidth is ∼30 GHz under pulsed bias. © 1996 American Institute of Physics.

    Notes: Summary. The effects of several factors on the uptake of salt during the brining of herring for kippering have been studied. the most important factors were the brine concentration, the brining time and the rate of stirring. the orientation of the fish (skin up or skin down on the brine surface), the oil content and the size of the fish were less important.

    Nature and orientation of ice in frozen fish (1966)

    Notes: The ice component of frozen fish muscle has been examined by X-ray diffraction. Only the common hexagonal form was observed, but line intensities indicated strong orientation of the crystallites. The c-axis is shown to be perpendicular to the direction of freezing; the muscle fibre direction does not appear to affect the direction of orientation to a noticeable extent.
