A Tool to Model the Fate and Transport of Indoor Microbiological Aerosols (FaTIMA)

June 1, 2020
Author(s)
William S. Dols, Brian J. Polidoro, Dustin G. Poppendieck, Steven J. Emmerich
The web-based tool Fate and Transport of Indoor Microbiological Aerosols (FaTIMA) allows for the determination of the indoor fate of microbiological aerosols associated with ventilation, filtration, deposition and inactivation mechanisms. FaTIMA provides a

Design and Realization of a Sputter Deposition System for the in situ and in operando Use in Polarized Neutron Reflectometry Experiments: Novel Capabilities

June 1, 2020
Author(s)
Jingfan Ye, Alexander Book, Sina Mayr, Henrik Gabold, Fankai Meng, Helena Schafferer, Ryan F. Need, Dustin Gilbert, Thomas Saerbeck, Jochen Stahn, Peter Boni, Wolfgang Kreuzpaintner
Recently, the design and realization of a sputter-deposition system for in situ and in operando neutron reflectometry (PNR) was reported. The device allows magnetic thin films and heterostructures to be grown, while the sample remains aligned in the

Evolution of transmitted depolarization in diffusely scattering media

June 1, 2020
Author(s)
Thomas A. Germer
We performed Mueller matrix Monte Carlo simulations of the propagation of optical radiation in diffusely scattering media for collimated incidence and report the results as a function of thickness and the angle subtended by the detector. For sufficiently

Generating GHZ states with squeezing and post-selection

June 1, 2020
Author(s)
Byron Alexander, Hermann Uys, John Bollinger
Many quantum state preparation methods rely on a combination of dissipative quantum state initialization, followed by unitary evolution to a desired target state. Here we demonstrate the usefulness of quantum measurement as an additional tool for quantum

IFCC working group recommendations for correction of bias caused by non-commutability of a certified reference material used in the calibration hierarchy of an end-user measurement procedure

June 1, 2020
Author(s)
Johanna Camara, W. Greg Miller, Jeffrey R. Budd, Neil Greenberg, Weykamp Cas, Harald Althaus, Heinz Schimmel, Mauro Panteghini, Vincent Delatour, Ferruccio Ceriotti, Thomas Keller, Douglas Hawkins, Robert Rej, Finlay MacKenzie, Elina van der Hagen, Hubert W. Vesper
Establishing metrological traceability to a matrix-based certified reference material (CRM) that has been validated to be commutable among a group of measurement procedures (MPs) is central to producing equivalent results for a measurand in clinical

Magnetic Field Frustration of the Metal-Insulator Transition in V 2 O 3

June 1, 2020
Author(s)
J. Trastoy, A. Camjayi, J. del Valle, Y. Kalcheim, J.-P. Crocombette, Dustin A. Gilbert, Julie Borchers, J. E. Villegas, D. Ravelosona, M. J. Rozenberg, Ivan K. Schuller
Despite decades of efforts, the origin of metal-insulator transitions (MITs) in strongly-correlated materials remains one of the main longstanding problems in condensed-matter physics. An archetypal example is V 2O 3, which undergoes simultaneous

Progress Towards Operation of a Deuterium Cold Neutron Source at the NCNR

June 1, 2020
Author(s)
John M Jurns, Michael Middleton, Robert E. Williams
The NIST Center for Neutron Research (NCNR) operates a 20 MW research reactor that produces neutrons for a suite of 30 neutron scattering instruments. 70% of these instruments use cold neutrons (E 2), which is in turn cooled by a recently commissioned 7 kW
