A survey is presented of the galactic plane in the J = 1 − 0 transition of CO. About 73,000 spectra were obtained with the 7 m telescope at Bell Laboratories over a ten-year period. The coverage of the survey is (l, b) = (−5◦ to 117◦,−1◦ to +1), or 244 square degrees, with a grid spacing of 3 for |b| < 0.5, and a grid spacing of 6 for |b| > 0.5. The data presented here have been resampled onto ...

Observations of radar speckle patterns tied to the rotation of Mercury establish that the planet occupies a Cassini state with obliquity of 2.11 +/- 0.1 arc minutes. The measurements show that the planet exhibits librations in longitude that are forced at the 88-day orbital period, as predicted by theory. The large amplitude of the oscillations, 35.8 +/- 2 arc seconds, together with the Mariner...

It is of great important to study pulsar beam shapes if we are concerned with emission theories and pulsar birth rate. Both observations[9, 16] and/or the ICS model[10] show that different emission components are emitted from different heights. The relative longitude phase shifts due to different heights of emission components and to the toroidal velocity of electron are considered in this pape...

We have analyzed the origin of cardiac progenitors in the zebrafish embryo by injection of single blastomeres with a lineage tracer dye, and examined the formation of the zebrafish heart tube by serial sectioning of immunostained embryos. At the 512-cell stage (early blastula), most cardiac progenitors lie in a marginal zone that extends from 90 degrees longitude (midway between the future dors...

We have observed about 16 absorption lines of the ν2 SO2 vibrational band on Io, in disk-integrated 19 μm spectra taken with the TEXES high spectral resolution mid-infrared spectrograph at the NASA Infrared Telescope Facility in November 2001, December 2002, and January 2004. These are the first ground-based infrared observations of Io’s sunlit atmosphere, and provide a new window on the atmosp...

We propose a generic framework for an active leader-follower surveillance system. The system can ingest inputs from a variety of multimodal leader sensors: Radars, Automatic Identification Systems (AIS), or cameras. Rule and learning based pattern recognition techniques are performed on the leader sensors to infer unusual behaviors and events. In order to calibrate the follower PTZ cameras to t...

In order to perform true bicoordinate navigation, migratory birds need to be able to determine geographic latitude and longitude. The determination of latitude is relatively easy from either stellar or magnetic cues [1-3], but the determination of longitude seems challenging [4, 5]. It has therefore been suggested that migrating birds are unable to perform bicoordinate navigation and that they ...
