Cumulative Risk Estimation for Chemical Mixtures
In reality, humans are always exposed to a combination of toxic substances and seldom to a single agent. Simultaneous exposure to a multitude of chemicals could result in unexpected consequences.

متن کاملSpeedSeg: A technique for segmenting pen strokes using pen speed
We present SpeedSeg, a technique for segmenting pen strokes into lines and arcs. The technique uses pen speed information to help infer the segmentation intended by the drawer. To begin, an initial set of candidate segment points is identified. This set includes speed minima below a threshold, and curvature maxima at which the pen speed is also below a threshold. The ink between each pair of co...

متن کاملSegmentation of Pen Strokes Using Pen Speed
We present a technique for segmenting pen strokes into lines and arcs. The technique uses pen speed information to help infer the segmentation intended by the drawer. To begin, a set of candidate segment points is identified. This set includes speed minima below a threshold computed from the average pen speed. It also includes curvature maxima at which the pen speed is again below a threshold. ...
متن کاملThe need for skin pen marking for sentinel lymph node biopsy: A comparative study
Introduction: There is a consensus in the literature that sentinel lymph node biopsy is the standard procedure for axillary staging in early stage (I and II) breast cancer patients. Usually during lymphoscintigraphy, the location of the sentinel lymph node is marked on the skin by an indelible ink. In this study we evaluated this issue in our patients. Methods: 40 ...
