Methodology and timing of standardization [PDF]
Journal of Thoracic Disease, 2019 In the last decade, uniportal VATS has increasingly been used for major lung resections as it has revolutionised the way thoracic surgeons treat pulmonary lesions. Uniportal VATS has represented an authentic innovation in thoracic surgery because it represents an ideal link between reduced morbidity and enhanced recovery.

Chip-Scale Ultra-Low Field Atomic Magnetometer Based on Coherent Population Trapping
Sensors, 2021 We report a chip-scale atomic magnetometer based on coherent population trapping, which can operate near zero magnetic field. By exploiting the asymmetric population among magnetic sublevels in the hyperfine ground state of cesium, we observe that the ...

Precision measurement of transverse velocity distribution of a strontium atomic beam
AIP Advances, 2014 We measure the transverse velocity distribution in a thermal Sr atomic beam precisely by velocity-selective saturated fluorescence spectroscopy. The use of an ultrastable laser system and the narrow intercombination transition line of Sr atoms mean that ...
