AbstractCompOSE is a data base of equations of state (EoS) with detailed information on the thermodynamic, compositional and microscopic properties of dense matter that can be used in astrophysical simulations. It is available online and hosted by the Observatoire de Paris at Meudon. The development and main features of CompOSE are presented in this overview. Besides the furnishing of data tables in various EoS categories using a specific, flexible format, computational tools are provided to extract and manipulate the stored data either by employing codes for download or through a web interface. Comprehensive documentations of the EoS models with links to the original literature and an extensive manual are available. Prospects for the future development are indicated.

Final Text

The tannaitic legal Midrashim did not all survive and are not all known to us in a complete independent form. David Zvi Hoffman was one of the first scholars to recognize the 13th century Yemenite Midrash, Midrash haGadol, written by R. David of Aden, as a major source of the lost legal Midarshim. He published the Midrash Tannaim, containing all of the tannaitic looking paragraphs from Midrash haGadol on the book of Deuteronomy. However, the author of Midrash haGadol often introduced changes into the material he borrowed from rabbinic and medieval sources. The resulting passages often seem to be unparalleled tannaitic sources, when in fact they are not. This article proposes a re-examination of the Mekhilta material as found in the Midrash haGadol, in order to reconstruct more accurately the tannaitic text. We propose a methodology for contending with this challenge, via a new approximate-matching algorithm designed to identify modified sources of this sort. Using this algorithm, we first compared Hoffman’s Midrash Tannaim on Deuteronomy to the Sifre, filtering out all parts of the text that are simply reworkings of the Sifre, despite many interpolations, omissions, and modified words. Having removed the Sifre passages from within the Midrash Tannaim text, we then proceeded to the next stage, in which we investigated the presence of reworked Maimonidean excerpts within the remaining text. The Maimonidean excerpts pose a particular challenge, because their reuse in the Midrash haGadol involves not only modifications and interpolations, but also changes of order. We describe the modifications that were necessary to the algorithm in order to handle these out-of-order cases of reuse as well. We have thus far succeeded in identifying and removing the reworked material appropriated from the Sifre and from Maimonides, and in the future we plan to tweak the algorithm such that it can successfully identify additional rabbinic passages as well, including the Babylonian and Palestinian Talmudic material, and other midrashic compilations. This will ultimately allow us to produce a final text approximating the original Mekhilta, to the greatest extent possible.

A symposium on the future of the International Latitude Service (I. L. S.) is to be held in Helsinki in July 1960. My report for the symposium consists of two parts. Part I, denoded (Mk I) was published [1] earlier in 1960 under the title “Latitude and Longitude, and the Secular Motion of the Pole”. Part II is the present paper, denoded (Mk II).

Second-epoch photographs have now been obtained for nearly 850 of the 1246 fields of the proper motion program with centers at declination -20° and northwards. For the sky at 0° and northward only 130 fields remain to be taken in the next year or two. The 270 southern fields with centers at -5° to -20° remain for the future.

Human And Mouse

Metaphase chromosomes from human and mouse cells in vitro are isolated by micrurgy, fixed, and placed on grids for electron microscopy. Interpretations of electron micrographs by current methods indicate the following structural features.Chromosomal spindle fibrils about 200Å thick form fascicles about 600Å thick, wrapped by dense spiraling fibrils (DSF) less than 100Å thick as they near the kinomere. Such a fascicle joins the future daughter kinomere of each metaphase chromatid with those of adjacent non-homologous chromatids to either side. Thus, four fascicles (SF, 1-4) attach to each metaphase kinomere (K). It is thought that fascicles extend from the kinomere poleward, fray out to let chromosomal fibrils act as traction fibrils against polar fibrils, then regroup to join the adjacent kinomere.

Freeze Etching

In his pioneering demonstration of the potential of freeze-etching in biological systems, Russell Steere assessed the future promise and limitations of the technique with remarkable foresight. Item 2 in his list of inherent difficulties as they then stood stated “The chemical nature of the objects seen in the replica cannot be determined”. This defined a major goal for practitioners of freeze-fracture which, for more than a decade, seemed unattainable. It was not until the introduction of the label-fracture-etch technique in the early 1970s that the mould was broken, and not until the following decade that the full scope of modern freeze-fracture cytochemistry took shape. The culmination of these developments in the 1990s now equips the researcher with a set of effective techniques for routine application in cell and membrane biology.Freeze-fracture cytochemical techniques are all designed to provide information on the chemical nature of structural components revealed by freeze-fracture, but differ in how this is achieved, in precisely what type of information is obtained, and in which types of specimen can be studied.
