The Jesuit Joachim Bouvet established an analogy between the binary arithmetic developed by Leibniz and the diagram Fuxi liushisi gua fangwei (or FX64), attributed to Shao Yong, which organizes the sixty-four hexagrams according to the Fuxi/Xiantian order. Consequently, this diagram could be considered as binary. Some scholars argue that the diagram is not binary because of the different construction of the two systems and the “wrong” reading direction used by Bouvet and Leibniz—opposite to the one used in China. Nevertheless, by a superimposition of Leibniz’s binary table and of the derivation table used to construct the diagram, this article shows that the diagram is binary, since it is constituted of two elements and the binary system can use other symbols than 0 and 1. The reverse methodology used in constructing the two systems because of their different purpose—division for the FX64 diagram and multiplication for Leibniz’s dyad—allows their reading from either one direction or the reverse. This does not affect the fact that they are both binary, since it leads to the same form and structure.

The American people have become used to government trickery in foreign affairs—wars and interventions based on lies and falsified evidence, “national security” used to justify the whittling away of privacy, classification of documents to hide embarrassing disclosures, massaging of budget figures to mask outrageous spending on arms, and demands for new weapons when already in possession of an unmatched conventional and nuclear arsenal.

This paper highlights the role that the World Wide Web (WWW) has to play as an aid to psychiatry. A basic history of the WWW is provided as is an introduction to some search techniques involved with the WWW. The literature on applications potentially relevant to psychiatry is reviewed using computer search facilities (BIDS, PsychLit and Medline). The WWW is one of the aspects of the Internet that possesses a huge potential for exploitation, both the clinical and research psychiatrist are able to benefit from its use.

Zhou Fengwu, renowned scholar and Taiwan's foremost paleographer, passed away at the age of sixty-nine.

HK Lac was observed at Konkoly Observatory between 1976-1981, the details of its story have been described in a previous paper (Olah, 1979).

The aim of this investigation is to give a possible description of the strong variations in the light curve of the star.

Searching for a more accurate period, it became obvious that the same period was not applicable to all the data. Therefore, a new period was derived for each different cycle by the Lafler-Kinman method. Unfortunately, due to the small number of data in the data sets these newly derived periods have an error of about 0.1 day.

Fourier coefficients are a valuable tool in the study of a wide variety of pulsating stars. They can be used to derive various physical parameters, including mass, luminosity, metallicity and effective temperature and are frequently used to discriminate between different pulsation modes. With the increase in large-scale surveys and the availability of data on the Internet, the number of Fourier coefficients available for study has expanded greatly and it is difficult to find all current data for individual stars or a subset of stars. To assist others in obtaining and making use of Fourier coefficients, an archive of published values of Fourier coefficients has been set up. Users can search for data on individual stars or for a range of parameters. Several Java programs are used to display the data in a variety of ways. The archive is located at the Web site http://www.earth.uni.edu/fourier/.

We have used the Automated Plate Scanner (APS) at the University of Minnesota to digitize glass copies of the blue and red plates of the original Palomar Observatory Sky Survey (POSS I) with |b| > 20°. The APS Image Database is a database of all digitized images larger than the photographic noise threshold. It includes all of the matched images in the object catalog, as well as those unmatched images above the noise threshold. The matched image data of the catalog has the advantage of confirming the reality of the image. This is especially important for small images near the plate limit. But these are not all of the detected real images; very blue or very red faint objects may be excluded by this matching requirement. The image database allows information on them to be retrieved, and is therefore a valuable complement to the object catalog. The operation of the APS and the scanning procedures are described in detail in Pennington et al. (1993). We are now processing plate data into the image database. A set of query forms, a tutorial and documentation can be found at http://isis.spa.umn.edu/IDB/homepage.idb.html.

The observation of an area of 120° × 56° centered on RA=8h DEC=20° at 408 MHz was the first astronomical use of the MPIfR 100-m telescope (1970) and was designed to compile a complete sky survey using also data from Jodrell Bank and Parkes (Haslam et al., 1982). The observation of the northern sky at 1420 MHz started in 1972 using the Stockert 25-m telescope and was finished in 1976 (Reich and Reich 1986). This survey has been completed to an all sky survey using data from Villa Elisa (Argentina). The two surveys are absolutely calibrated. The angular resolutions are 0.8° and 0.59°, respectively. A number of surveys of the Galactic plane have been made with the 100-m telescope at arc minute angular resolution. Surveys at 2695 MHz (|b| ≤ 5°) (Reich et al. 1990, Fürst et al. 1990) and at 1410 MHz (|b| < 4°) (Reich et al. 1990) are public.

At medium Galactic latitudes (up to |b| = 20°) the emission consists mainly of faint extended ridges or arcs superimposed on the still dominating, about 10 times stronger, diffuse Galactic emission. They have never been investigated in a systematic way although they provide important clues for the understanding of the “disk-halo connection”. This region is covered by new observations at 1400 MHz with the 100-m telescope.

Scarparo has constructed counterexamples to Matui’s HK-conjecture. These counterexamples and other known counterexamples are essentially principal but not principal. In the present paper, a counterexample to the HK-conjecture that is principal is given. Like Scarparo’s original counterexample, our counterexample is the transformation groupoid associated to a particular odometer. However, the relevant group is the fundamental group of a flat manifold (and hence is torsion-free) and the associated odometer action is free. The examples discussed here do satisfy the rational version of the HK-conjecture.
