Automated planning is a branch of artificial intelligence which deals with the computation of the best strategies of action sequences, typically for execution by machines or robots (Russell & Norvig, 2003). In general, the automated planning solutions are complex, combinatory and have to be searched in a multidimensional space. Solutions usually resort to iterative trial and error processes com...

Pulmonary ischemia-reperfusion injury is complex and involves many cell types and mechanisms of action. Van Putte and coworkers have attempted to provide insight into and describe some of the complex components of this process. Their study describes two new components of the multifaceted process of reperfusion injury. The time-dependent course of neutrophil activation and the discovery of progr...

By now many Canadians know that February is heart month, thanks to annual canvassing of the Heart and Stroke Foundation of Canada. February, it turns out, is the peak month for heart attacks, but did you ever wonder why? If you subscribe to the notion that high cholesterol is the main or major risk factor for heart attacks, then you would be surprised to know that seasonal differences in choles...

We have used the 15-m Swedish European Southern Observatory (ESO) Submillimetre Telescope (SEST) to observe the J = 1 → 0 and J = 2 → 1 transition lines of CO in 30 Southern hemisphere Seyfert galaxies from the extended 12-μm sample of Rush, Malkan & Spinoglio. We detected CO J = 1 → 0 in 16 out of the 30 Seyfert galaxies and CO J = 2 → 1 in 17 out of the 30 Seyfert galaxies. From the observed ...

We present a framework for estimating 3D relative structure (shape) and motion given objects undergoing non-rigid deformation as observed from a fixed camera, under perspective projection. Deforming surfaces are approximated as piece-wise planar, and piece-wise rigid. Robust registration methods allow tracking of corresponding image patches from view to view and recovery of 3D shape despite occ...

Several methods of automated line simplification exist, but most involve parameters selected arbitrarily or heuristically, with little or no reference to the scale change between original data and generalized output. Also, while routines such as the Douglas-Peucker algorithm achieve simplified line correlates by retention of characteristic points from the input line, little analysis has been de...

BACKGROUND/AIM Acrylic lens size and shape may influence the rate of posterior capsule opacification (PCO) and need for Nd:YAG capsulotomy. The aim of this study is to compare the Nd:YAG capsulotomy rate of the three piece acrylic/PMMA AcrySof MA series lens with the one piece acrylic AcrySof SA series lens. METHODS 434 eyes of 329 patients who had cataract extraction and implantation of one ...

This is based on [A]. In [A], I explained several theorems which focused on a famous theorem of [KL] that two elements of the symmetric group belong to a same left cell if and only if they share a common Q-symbol. The first half of [A] was about the direct proof of this theorem (Theorem A), and the second half was about the relation between primitive ideals and left cells, and I explained anoth...
