    Notes: Abstract The incidence of SIDS in western countries has decreased since the late 1980s after active SIDS prevention campaigns. By contrast, both Taiwan and Japan have reported an increase in incidences. In this report data from England, Wales, Scotland, Northern Ireland, Japan and Hong Kong are analysed. Regression coefficient and linearity of regression tests were used to determine if there was any significant increase or decrease in post-neonatal mortality (PNNM), SIDS mortality and mortality among infants 1–5 months old. A statistically significant decrease in SIDS was recognized in England, Wales, Scotland and Northern Ireland, whereas statistically significant increases were noted for Japan and Hong Kong. However in Japan and Hong Kong both the PNNM and mortality of infants between 1–5 months in age fell significantly, suggesting that the increased SIDS rates could be due to a change in diagnostic labelling. Further study will be required to determine whether this increase in the incidence of SIDS is genuine or only an artifact.

    Notes: Abstract Non-cuprate layered perovskite Sr2RuO4, which is an analogue of (La,Sr)2CuO4, exhibits superconductivity below Tc≈1K. We have synthesized a new system Sr3−xCaxRu2Oy and found the solubility of Ca to be at least as much as x = 2. These samples are not superconductive down to 2K but magnetically ordered. The x dependence of the lattice parameters and that of Tmag clearly indicate that there are at least two distinct structural phases in Sr3−xCaxRu2Oy.

    Notes: Abstract We discuss some of the current issues on the copper-free layered perovskite superconductor Sr2RuO4, for which a sharp transition at Tc = 1.2 K has been reproducibly obtained. The normal state is characterized as an essentially twodimensional Fermi liquid, and the coherent interlayer transport is established only at low temperatures. The cylindrical Fermi surface observed by de Haas-van Alphen experiments is consistent with other thermodynamic and transport properties. Although the specific heat jump across Tcconfirms the bulk superconductivity, the large residual T-linear term which correlates with the variation in Tcis unusual and suggestive of unconventional pairing.

    Notes: Abstract We have investigated the normal-state conduction of superconducting Sr2RuO4 (Tc ∼ 1K), which is isostructural to La2−xSrxCuO4. The resistivity of single crystals shows a crossover at TM∼130K from 3D metallic conduction at lower temperatures to 2D one at higher temperatures. Concerning the temperature dependence of the out-of-plane resistivity, we present a systematic interpretation based on competition between the life time of the quasiparticles and the time for the quasiparticles to travel between the adjacent RuO2 planes.
