Milligram mass metrology using an electrostatic force balance

Author(s)
Gordon A. Shaw, Julian Stirling, John A. Kramar, Alexander D. Moses, Patrick J. Abbott, Richard L. Steiner, Andrew D. Koffman, Jon R. Pratt, Zeina J. Kubarych
Although mass is typically defined within the International System of Units (SI) at the Kilogram level, the pending redefinition of the SI provides an...

Bridging classical and quantum mechanics

Author(s)
Darine El Haddad, Frank C. Seifert, Leon S. Chao, Shisong Lee, David B. Newell, Jon R. Pratt, Carl J. Williams, Stephan Schlamminger
Using a watt balance and a frequency comb, a mass-energy equivalence is derived. The watt balance compares mechanical power measured in terms of the meter, the...

The growing interest in determining structures of macromolecules containing deoxyribonucleic acid (DNA) in solution and their structure-function relationship...

Elevated urinary levels of 8-hydroxy-2’-deoxyguanosine, (5’R)- and (5’S)-8,5’-cyclo-2’- deoxyadenosines, and 8-iso-prostaglandin F2¿ as potential biomarkers of oxidative stress in patients with prediabetes

Author(s)
M Miral Dizdar, Melis Kant, Merve Akis, Mehmet Calan, Tugba Arkan, Firat Bayraktar, Huray Islekel
Prediabetes is the preclinical stage of type 2 diabetes mellitus with intermediate state of hyperglycemia. Hyperglycemia results in a state of oxidative stress...

Nanoscale imaging of magnetization reversal driven by spin-orbit torque

Author(s)
Ian J. Gilbert, Andrew P. Chen, Daniel B. Gopman, Andrew L. Balk, Daniel T. Pierce, Mark D. Stiles, John Unguris
We use scanning electron microscopy with polarization analysis (SEMPA) to image deterministic, spin-orbit torque driven magnetization reversal of in-plane...
