Stop Spacing

By utilizing a computer-aided simulation approach, this research analyzes the detailed effect of the length of stop-spacing on the transport time per passenger-kilometer of a typically formed Chinese intercity passenger train hauled by, respectively, representative types of the locomotives utilized in China for different target speeds. It is empirically confirmed that a stop-spacing longer than approximately 20.00 km has little influence upon the transport efficiency of the train. In contrast, shortening the stop-spacing below about 20.00 km increases the transport time per passenger-kilometer of the train evidently, in particular for a target speed much higher than some 40.00 km/h. Therefore, the target speed of such a train providing transport service on a railway line whose transport capacity has not been much consumed ought to be changeable according to the length of each stop-spacing rather than consistent for the whole trip.

Dimensional Reconstruction

Structurally-oriented biologists examine cells, tissues, organelles and macromolecules in order to gain insight into cellular and molecular physiology by relating structure to function. The understanding of these structures can be greatly enhanced by the use of techniques for the visualization and quantitative analysis of three-dimensional structure. Three projects from current research activities will be presented in order to illustrate both the present capabilities of computer aided techniques as well as their limitations and future possibilities.The first project concerns the three-dimensional reconstruction of the neuritic plaques found in the brains of patients with Alzheimer's disease. We have developed a software package “Synu” for investigation of 3D data sets which has been used in conjunction with laser confocal light microscopy to study the structure of the neuritic plaque. Tissue sections of autopsy samples from patients with Alzheimer's disease were double-labeled for tau, a cytoskeletal marker for abnormal neurites, and synaptophysin, a marker of presynaptic terminals.
