OBJECTIVE This study presents data on the use of complementary and alternative therapies to treat anxiety and depression in the United States. METHOD The data came from a nationally representative survey of 2,055 respondents (1997-1998) that obtained information on the use of 24 complementary and alternative therapies for the treatment of specific chronic(More)
This paper describes a method of generating a path between two points of a cellular array, with some cells being specified as obstacles. The method combines two techniques: A line search is first directed toward the target. This is a fast and extremely effective method on boards with plenty of space. When the line search hits an obstacle, an expansion(More)
The paper describes a new router which develops all connections simultaneously. Routes do not exist as lines, but rather as connected irregularly shaped areas which grow and retract in an amoeba-like manner. It is as if some routes are being rerouted, but it is all done at once. Because the cell map is scanned sequentially, the data handling and storage is(More)
A channel router which is to be effective for general-purpose automatic routing must be able to use different sets of routing criteria priorities, in a controllable manner. We present an approach to channel routing with compaction in which channel compaction is adaptable to several routing criteria priorities. We show how overall channel routing performance(More)
Maze routers provide powerful and flexible routing algorithms, but require storage of information for every routing grid and layer. With the advance of manufacturing technology, the number of these grids is often so large that routing programs either run out of memory or become very slow due to excessive paging. This paper presents a new data organization(More)
In the hierarchical layout of rectangular blocks, the routing area naturally breaks into a set of adjacent rectangles. These rectangles can be used as basis for both loose routing and the final track assignment. The paper explores some ways of structuring the required data. More details about generalized Lee routing, and practical results are left for(More)
UNLABELLED Mass spectrometers are sophisticated, fine instruments which are essential in a variety applications. However, the data they produce are usually interpreted in a rather primitive way, without considering the accuracy of this data and the potential errors in identifying peaks. Our new approach corrects this situation by dividing the LC-MS output(More)
