Many of us are feeling isolated as travel and education budgets are restricted while patient flow demands, H1N1 and the pressures of work increase. This is a time for us, the chief executive nurses, to take a leadership position in our organizations. Two years ago we reviewed the strategic plan of the Academy of Canadian Executive Nurses (ACEN). The primary foci for ACEN are to network and set ...

In the past several years, a number of different language modeling improvements over simple trigram models have been found, including caching, higher-order n-grams, skipping, modified Kneser-Ney smoothing, and clustering. While all of these techniques have been studied separately, they have rarely been studied in combination. We find some significant interactions, especially with smoothing tech...

Chemical, genetic and cell biology tools have been used to probe which RNA-protein granules behave like liquids and which behave like solids.

H omotypic adhesion between surface receptors called cadherins is essential to the integrity of epithelial sheets. But cadherins aren't just passive anchors that allow cells to stick together. Instead, by coupling to the actin cytoskeleton, they can generate tension to affect the structure and resiliency of individual cells and tissues. How are contractile forces generated at cadherin junctions...

Editorial We're All in this Bus Together The conference day has officially gone into overtime—after all the talks, posters, dinner, and drinks, we're now headed back to our hotels in the city, a half-hour's drive down the mountain-side. I'm a few rows back from the front of the bus, and it's crowded-baron a -Friday-night loud and just as energized. Over the noise, I catch only enough of my seat...

Given a robot and a workspace, probabilistic roadmap planners (PRMs) build a roadmap of paths sampled from the workspace. A roadmap node is a single collision{free robot con guration, randomly generated. A roadmap edge is a sequence of collision{free robot con gurations which interpolate the path from one roadmap node to another. Queries to the roadmap are (start, goal) pairs. If both the start...

1998 Miles Conrad Memorial Lecture NFAIS Annual Conference February 24, 1998 Philadelphia, PA Kent Smith, Deputy Director, National Library of Medicine © 1998 Kent Smith Good morning and thank you for the honor to present this lecture in the memory of Miles Conrad, first president of NFAIS and one of its original founders. The lecture series is a fitting memory to a man of vision, strength, dev...

E lectronic packaging at APL is radically different today than it was in the past. Limited funding, shorter schedules, packaging densities, and higher power requirements place an entirely new set of criteria on the packaging designs. New processes and fabrication techniques are evolving faster than the established reliability framework can support. Electronic packaging design involves many sepa...
