A shorter half-life will generate a larger activity (which means more decay per unit of time). Intuitively, this should seem correct: if something is decaying more rapidly (i.e., a shorter half-life), you should observe more disintegrations per second. Another term that is commonly ...
The length of stay displayed a decreasing trend with MVIGS, and the operative time was significantly reduced in MvIGS compared with 2D fluoroscopy for an average of 63.6 minutes (294.5 卤 15.5 vs 358.1 卤 60.6 min, P < 0.001). Conclusion: In pediatric spinal deformity correction surgery, Mv...
State-transition diagram for each of the groups over time intervals. Patients in a failure-free state can either stay in failure-free state, experience progression (progressive disease), or die (death). After progression, patients can either remain progressive or die. Death is the absorbing ...
The chart 500 indicates that one type of auxiliary sensor is a “being worn” sensor. The “being worn” sensor would indicate whether the glasses are being worn by its user. The “being worn” sensor can be performed using, for example, a thermal sensor, a motion detector, a stress sen...

Slovis et al. [24] focused on radiation exposure from CT scans in ICU patients and the associated lifetime attributable risk (LAR) of cancer. Conducted via an electronic chart review from January 2007 to December 2011, this study calculated the CED for each CT scan and predicted the LAR fo...
The only case where the energy does not stay in the water is that where the light gets reflected or scattered back out of the ocean. The share of that is very small excluding that light that gets reflected already before it has really entered the ocean at all. ...
time during the solar cycle, and duration in deep space during transit. NASA has aggregated several Mars mission scenarios, known as design reference missions (DRMs), which span from short transit times in deep space with short duration stays on the Martian surface to much longer missions that ...
Comparable to our PSIs, waiting time until start of treatment is emphasized in the QI catalogues by Gabriele et al. [69] and Vaandering [38]. In “Safety is no accident” structured timely organization of patient paths are defined as important aspect [21]. RO-specific recommendations for ...
Mean operative times were 165 minutes (range, 106–264 minutes), and hospital stay averaged 4.6 days (range, 3–7 days). Residual disease was found in 7 patients (29.2%). There were 7 early postoperative complications (29%) and 8 late complications (33.3%; 1—rectovaginal fistula; 1—...
