From page 26...
... Fundamental work includes research on single atoms and photons, quantum degenerate atomic gases of bosons and fermions, cavity optomechanics, and quantum optics. Spectroscopic work, with its long and distinguished history, includes the atomic spectroscopy database, and metrology covers aspects that include fundamental measurements of mass and force; basic electrical measurements of voltage, ampere, and resistance; and time-synchronized measurements for smart grid applications.

... Fundamental Electrical Measurements, Applied Electrical Metrology, Mass and Force, and Synchrometrology The incremental improvements in the key electrical measurements triangle (voltage, current, and resistance) are demonstrating continued PML leadership in attempting to increase accuracy while reducing uncertainties.
From page 28...
... The ability of the PML to maintain its leading position in what is one of the oldest metrology areas is an accomplishment. PORTFOLIO OF SCIENTIFIC EXPERTISE Through its highly productive scientific exchange, with over 150 journal papers published in 2014, numerous awards received in the last 5 years, and the hosting of over 90 guest researchers while maintaining its own staff of 75, the division remains an essential focal point of the world efforts on physical measurement sciences.
From page 29...
... The machine was built several decades ago, and the PML group performed precise modeling of the deterioration phenomena associated with the material galling that developed in key structural components within the stainless steel weight stack. In the Fundamental Electrical Measurements Group and Applied Electrical Metrology Group, some of the efforts are covered by one or two people only, so staffing may have to be reassessed.
From page 30...
... JILA has a long and successful tradition along these lines, and a similar outcome can be expected from JQI as it further establishes itself. Fundamental Electrical Measurements, Applied Electrical Metrology, Mass and Force The dissemination of primary units realizations is an extremely important mission and needs to be supported, with the focus on making the secondary units cheaper but with even more manageable uncertainties.
