We report on a series of 42 measurements of the transition frequency of the 429 THz (5s^{2}) ^{1}S_{0}–(5s5p) ^{3}P_{0} line in ^{87}Sr taken over three years from 2017 to 2019. They were performed at the Physikalisch-Technische Bundesanstalt (PTB)

IntroductionAirway compromise is the third most common cause of preventable battlefield death. Surgical cricothyroidotomy (SC) is recommended by Tactical Combat Casualty Care (TCCC) guidelines when basic airway maneuvers fail. This is a descriptive a

We compare two optical clocks based on the $^2$S$_{1/2}(F=0)\to {}^2$D$_{3/2}(F=2)$ electric quadrupole (E2) and the $^2$S$_{1/2}(F=0)\to {}^2$F$_{7/2}(F=3)$ electric octupole (E3) transition of $^{171}$Yb$^{+}$ and measure the frequency ratio $\nu_{
