New Conversion Laws for CO Observations

New Antitrust Laws for the “New Economy”?

New 13 CO observations towards the Keplerian gaseous disk around

We present new high angular resolution observations of the 13 CO 1→0 rotational line towards the HBe star R Mon, obtained with the IRAM Bure In-terferometer, along with the previous results in the observed transitions 12 CO 1→0 and 2→1. We have used a flat disk model to fit the 12 CO 1→0 and 2→1, and 13 CO 1→0 emission, in a strip perpendicular to the outflow axis. The model assumes standard ab...

Kepler's Laws, Newton's Laws, and the Search for New Planets

Introduction. One of the high points of elementary calculus is the derivation of Kepler’s empirically deduced laws of planetary motion from Newton’s Law of Gravity and his second law of motion. However, the standard treatment of the subject in calculus books is flawed for at least three reasons that I think are important. First, Newton’s Laws are used to derive a differential equation for the d...

Representing Actions: Laws, Observations and Hypotheses

> We propose a modiication L 1 of the action description language A. The language L 1 allows representation of hypothetical situations and hypothetical occurrence of actions (as in A) as well as representation of actual occurrences of actions and observations of the truth values of uents in actual situations. The corresponding entailment relation formalizes various types of common-sense reasoni...

Some Observations Co Ncerning

One of the more perplexing aspects of mitosis has been the na ture of the mechan ism whereby the chromosomes are moved into their metaphase configuration. Early theories of chromosome movemen t which involved the spindle or chromosomal fibers later gave way to theories proposing alternate mechanisms, as spindle fibers came to be regarded as artifacts of fixation. In recent years, however, evide...
