nexus

 [nek´sus]
1. a bond, as between members of a series or group.

gap junc·tion

1. an intercellular junction formerly considered to be a tight, membrane-to-membrane junction (macula occludens) but now shown to have a 2-nm gap between apposed cell membranes; the gap is not void but contains subunits in the form of polygonal lattices, which are the intercellular aspects of the two connexons that fit together, forming a channel between the cytoplasms of the two cells; it occurs in epithelia, between certain nerve cells, and in smooth and cardiac muscle; it is believed to mediate electrotonic coupling, which allows ionic currents to pass from one cell to another.

2. areas of increased electrochemical communication between myometrial cells that aid in the propagation of the contractions of labor.

where [Pop.sub.Building] denotes the population of each building, ([People.sub.DWSTR]/DWSTR) is the number of people per dwelling structure type in each CD, DWSTR is the number of dwellings by structure type in each CD, and [NEXIS.sub.DWSTR] is the NEXIS count of dwellings for each building.
Since the initial development of NEXIS, validation of population estimates has led to a number of improvements.
For its part, Nexis dismisses the Dow Jones mass-market maneuver as meaningless.
He noted that five years ago, Nexis experimented unsuccessfully with letting Internet users search for free and download articles for a fixed fee.
