We have conducted several time-transfer experiments using the phase of the GPS carrier rather than the code, as is done in current GPS-based time-transfer systems. Atomic clocks were connected to geodetic GPS receivers; we then used the GPS carrier-phase observations to estimate relative clock behavior at 6-minute intervals.

The authors describe the use of GPS (Global Positioning System) for time coordination. When GPS first became available, it provided a quantum leap in time coordination with little or no effort on the part of the user. However, workers realized that with more sophisticated analysis techniques even greater accuracy could be wrung from GPS.

Interhemispheric Transfer Time in Sportsmen
Journal of Motor Behavior, 2012The authors' aim was to compare interhemispheric transfer time between 2 groups: highly skilled sportsmen and control subjects. Left- and right-handed individuals were included in the study. The Poffenberger paradigm was used to measure the crossed-uncrossed difference, representing the time to transfer information from one hemisphere to the other.

Embryo transfer: timing and techniques
Minerva Endocrinology, 2018Since the first successful human in vitro fertilization (IVF) pregnancy nearly 40 years ago, remarkable progress has been made in assisted reproductive technology (ART). Improvements in oocyte retrieval, embryo culture, genetic screening, and embryo selection have contributed to dramatic improvements in IVF outcomes.
