In-situ Temperature Calibration Capability for Dimensional Metrology

Author(s)
Prem K. Rachakonda, Daniel S. Sawyer, Balasubramanian Muralikrishnan, Christopher J. Blackburn, Craig M. Shakarji, Gregory F. Strouse, Steven D. Phillips
The Dimensional Metrology Group (DMG) at the National Institute of Standards and Technology (NIST) has developed a new in-situ temperature calibration system

New x-ray measurements shed light on discrepancy between experiment and QED

Author(s)
Lawrence T. Hudson, C T. Chantler, A.T. Payne, M N. Kinnane, John D. Gillaspy, L F. Smale, Albert Henins, J A. Kimpton, E Takacs
Quantum Electro-Dynamics (QED) is the best tested theory of our physical world, yet significant disagreements have emerged between attempts to apply QED to

Physical Properties of LiMn2-xMxO4 (M = Ni, Fe) Sol-Gel Nanopowders

Author(s)
E. Talik, L. Lipinska, A. Guzik, Pawel Zajdel, M. Michalska, M. Szubka, M. Kadziolka-Gawel, Rick L. Paul
The Pechini sol-gel method was applied to obtain LiMn 2-xT xO 4 (T=Ni, Fe; x = 0.1 to 0.5) nanopowders. Crystal and electronic structures, chemical composition

Author(s)
David J. Vanderah, Tadas Ragaliauskas, Mindaugas Mickevicius, Mariya Jankunec, Gediminas Niaura, Gintaras Valincius, Bozena Rakovska
Structure of the self-assembled monolayers (SAMs) used to anchor phospholipid bilayers to surfaces affects the functional properties of the tethered bilayer

PM Noise Measurement at W-Band

Author(s)
Archita Hati, Craig W. Nelson, David A. Howe
We present improved performance for a 92 - 96 GHz cross-spectrum phase modulated (PM) noise measurement system previously reported. The system is principally

Natural Scene Statistics in Infrared Images

Author(s)
Nicholas G. Paulter Jr., Todd R. Goodall, Alan C. Bovik
Natural Scene Statistics (NSS) produces powerful perceptually relevant tools that have been highly successful in image quality analysis of visible light images

Tunable Spin-Orbit Coupling via Strong Driving in Ultracold Atom Systems

Author(s)
Ian B. Spielman, Lindsay J. LeBlanc, Ross A. Williams, Matthew C. Beeler, Chunlei Qu, Ming Gong, Chuanwei Zhang
Spin-orbit coupling (SOC) is an essential ingredient in topological materials, conventional and quantum-gas based alike. Engineered spin-orbit coupling in

Short-Range Correlations in the Magnetic Ground State of Na4Ir3O8

Author(s)
Rebecca Dally, Tom Hogan, Alex Amato, Chris Baines, Jose Rodriguez Rivera, Michael J. Graf, Stephen D. Wilson
The magnetic ground state of the J eff = 1/2 hyper-Kagome lattice in Na 4Ir 3O 8 is explored via combined bulk magnetization, muon spin relaxation, and neutron

MECHANICS ANALYSIS OF MOLAR TOOTH SPLITTING

Author(s)
Amir Barani, Brian R. Lawn, Mark Bush, Herzl Chai
A model for the splitting of teeth from wedge loading of molar cusps from a round indenting object is presented. The model is developed in two parts: first, a

Cryocooled 10 V Programmable Josephson Voltage Standard

Author(s)
Alain Rufenacht, Logan A. Howe, Anna Fox, Robert E. Schwall, Paul Dresselhaus, Charles J. Burroughs, Samuel Benz
Implementation of programmable Josephson voltage standard (PJVS) circuits on cryocooler at 4 K is a challenge. The limited cooling power of the cryocoolers has

Experimental Bounds on Classical Random Field Theories

Author(s)
Joffrey K. Peters, Sergey V. Polyakov, Jingyun Fan, Alan L. Migdall
Alternative theories to quantum mechanics motivate important fundamental tests of our understanding and description of the smallest physical systems. Here we

Microwave Determination of the Volume of a Pressure Vessel

Author(s)
Michael R. Moldover, James W. Schmidt, Keith A. Gillis, James B. Mehl, John D. Wright
Using microwave techniques that are scalable to very large volumes, we measured the interior volume of a 0.3 m 3, commercially-manufactured, pressure vessel
