    Notes: The expression of the transcriptional regulator NAC1 is increased in the nucleus accumbens of rats withdrawn from cocaine self-administration, and in vivo studies indicate that the up-regulation is a compensatory mechanism opposing the acute effects of cocaine. Both mammalian two-hybrid assay and punctate localization largely in the nucleus suggest NAC1 is a transcriptional regulator. However, in this report it is shown that in differentiated PC12 and Neuro2A cells, as well as in primary cortical neurons, NAC1 is diffusely expressed not only in the cell nucleus but also in cytoplasm. Blockade of spontaneous electrical activity by tetrodotoxin prevented the diffuse expression of NAC1, and depolarization with high potassium concentrations induced diffuse cellular localization in non-differentiating cells. The use of protein kinase C (PKC) inhibitors and activator, as well as the systematic mutation of potential PKC phosphorylation sites in NAC1, demonstrated that phosphorylation of residue S245 by PKC is a necessary event inducing diffuse NAC1 expression outside of the nucleus. These observations indicate a potential non-transcriptional role for NAC1 in the brain.

    Notes: Nanometer-sized zinc aluminate (ZnAl2O4) particles were synthesized from heterometal alkoxides, [ZnAl2(OR)8], possessing an ideal cation stoichiometry for the ZnAl2O4 spinel. ZnAl2O4 is formed at 400°C, which is the lowest temperature reported for the formation of monophasic ZnAl2O4. 27Al magic-angle spinning nuclear magnetic resonance spectroscopy revealed that ZnAl2O4 possesses an inverse structure at 〈900°C, while the normal spinel phase is observed at higher temperatures. The homogeneity of the in-depth composition and Zn:Al stoichiometry (1:2) was confirmed by electron spectroscopy for chemical analysis. Evaluation of the valence-band spectra of ZnAl2O4 and ZnS suggested that the hybridization of O 2p and Zn 3d orbitals is responsible for lowering the bandgap in the latter. The average crystallite size showed an exponential relationship to the calcination temperature (X-ray diffractometry and transmission electron microscopy data). The optical spectra of different spinel powders (average particle sizes, 20–250 nm) showed that the absorption edge exhibits a blue shift as particle size decreases.

    Spherical reflector as an electromagnetic-missile launcher (1990)

    Notes: A spherical reflector illuminated by a point source is found to be capable of launching an electromagnetic missile. Since the surfaces of the reflector are not complete spherical surfaces, the problem cannot be solved by simple boundary matching. The electromagnetic fields have to be solved in three regions separately. The general solutions are matched on the boundaries to obtain a set of coefficient equations. Under the conditions for an electromagnetic missile, the coefficient equations are solved asymptotically. The evaluation of the Poynting vector shows that the energy radiated from the reflector has the same slow rate of decay as for the spherical lens.

    Curved electromagnetic missiles (1989)

    Notes: An interesting topic has been the possible behavior of transient fields in the limit of great distances from their sources. Under the physical restriction that the total energy radiated is finite, it has been shown that the energy reaching a distant receiver can decrease with distance much more slowly than the usual r−2. Such cases of slow decrease have been referred to as electromagnetic missiles. All of the wide variety of known missiles propagate in essentially straight lines. It is shown here that such a missile can follow a path that is strongly curved. An example of a curved electromagnetic missile is explicitly constructed and some of its simpler properties are discussed.

    The plasma waveguide with a finite thickness of cladding (1991)

    Notes: The properties of the plasma waveguide of finite thickness (plasma tube) have been studied. The analysis indicates that, in the case of finite thickness, most of the properties for the plasma waveguide with infinite thickness are retained. At high frequencies, such a plasma tube is still a nondispersive waveguide system. The losses due to the finite thickness of the cladding and the conductivity of the plasma are both small. The decay coefficient decreases with the thickness exponentially. With a thickness equal to the radius of the central core, the attenuation can be as low as 0.1 dB/km.

    Plasma waveguide: A concept to transfer electromagnetic energy in space (1991)
    [S.l.] : American Institute of Physics (AIP)

    Notes: This paper studies the possibility of using a laser-generated "plasma waveguide'' to transfer electromagnetic (EM) energy. The plasma waveguide is a cylindrical vacuum core surrounded by a plasma cladding. The analysis shows that guided-mode fields do exist inside the core. Like a general dielectric waveguide, the plasma waveguide is characterized by a "normalized frequency parameter'' (also called the V number). Although the permittivity of the plasma varies strongly with frequency, the V number surprisingly remains constant over the entire frequency range. Because of this property, the frequency dependence of the plasma waveguide is different; it has a wider high-frequency response than the general dielectric waveguide. The EM pulse can propagate in the plasma waveguide at close to the speed of light and keep its profile and shape unchanged. When the V number is smaller than 2.4048 (the first root of the zero-order Bessel function), only the single HE11 mode exists in the plasma waveguide. Unlike the dielectric waveguide, however, there is no high-frequency limitation for single-mode propagation. The EM fields outside the core in the plasma decrease exponentially with increasing radius. Thus, practically, a plasma cladding of sufficient thickness is all that is required to confine the EM wave. Such a plasma waveguide can be generated by a hollow laser beam in upper space and used for guiding EM pulses. A brief survey on laser-generated plasmas is given.
