OBJECTIVE To describe rounding practices in Canadian adult Intensive Care Units (ICU) and identify opportunities for improvement. DESIGN Mixed methods design. Cross sectional survey of Canadian Adult ICUs (n = 180) with purposefully sampled follow-up interviews (n = 7). MEASUREMENTS AND MAIN RESULTS Medical directors representing 111 ICUs (62%) participated in the survey. Rounding practices...

Slope rounding is discussed in the Roadside Design Guide as a practice that breaks the sharp edge in a highway cross section and the side slope. There have been past studies aimed at understanding the influence of slope rounding on vehicle trajectories for various slope conditions. These studies were conducted about twenty years ago and only looked at a small subset of vehicle types despite the...

Rounding. Dependent rounding is useful. Negative correlation is useful. Near-independence used. Entropy maximization often yields useful distributions. Goal of this paper is to explore if entropy maximization can be used to obtain distributions with near-independence properties.

In the minimum multiway cut problem, the goal is to find a minimum cost set of edges whose removal disconnects a certain set of k distinguished vertices in a graph. The problem is MAX-SNP hard for k > 3. Cglinescu, Karloff, and Rabani gave a geometric relaxation of the problem and a rounding scheme, to produce an approximation algorithm that has a performance guarantee of 3/2 1/k. In a subseque...

Discrete labeling problems are often solved by formulating them as an integer program, and relaxing the integrality constraint to a continuous domain. While the continuous relaxation is closely related to the original integer program, its optimal solution is often fractional. Thus, the success of a relaxation depends crucially on the availability of an accurate rounding procedure. The problem o...

Computational geometry classically assumes real-number arithmetic which does not exist in actual computers. A solution consists in using integer coordinates for data and exact arithmetic for computations. This approach implies that if the results of an algorithm are the input of another, these results must be rounded to match this hypothesis of integer coordinates. In this paper, we treat the c...

The effects of local anesthetics on cultivated macrophages were studied in living preparations and recorded in still pictures and time-lapse cine-micrographs. Exposure to 12mM lidocaine or 1.5 mM tetracaine resulted in rounding in 10-15 min. Rounding was characterized by cell contraction, marked increase in retraction fibrils, withdrawal of cell processes, and, in late stages, pulsation-like ac...

Ezrin/radixin/moesin proteins link the actin cytoskeleton to the plasma membrane. Two new reports have found that moesin phosphorylation is essential for mitotic cell rounding and identify a new role for cell rounding in spindle assembly.
