Journal of the American Medical Association, 1903 Not long ago a prominent clinician of Chicago requested the writer to contrive an apparatus by which chest contours could be accurately measured and recorded. Such an instrument was said to be needed by those who specialize in diseases of the thorax or who have any occasion to record thoracic conditions for statistical or other purposes.

Availability Evaluation of Overhead Contact Lines Based on a Stochastic Colored Petri Nets Model
IET Electrical Systems in Transportation, Volume 2025, Issue 1, 2025.Due to their nonbackup characteristics and constant exposure to outdoor conditions, the performance of overhead contact lines (OCLs) will gradually degrade over time and further result in equipment defects or frequent failures. These issues significantly impact system availability and incur substantial repair costs.
