A simple but effective improvement to the plumb-line algorithm

In this paper, we propose an improved plumb-line algorithm, the Partial-Scan Plumb-Line (PSPL) algorithm, to solve the point-in-region problem. In the PSPL algorithm, every edge of the region (or polygon) is represented as two half segments, and all half segments of the region are sorted according to their dominating points. This is a standard representation for regions in spatial databases, pr...

Gaining an understanding of these important structures is essential for accurate diagnosis, management, and prediction of the spread of infection in the hand. Typically, the proximal extent of the sheath in the thumb and little finger is more proximal than the flexor tendon sheaths in the other three fingers. Additio...
