Stuck in a moment: A view from the MIRE

April 20, 2017
Author(s)
Patrick Egan, Jack A. Stone Jr., Jacob Edmond Ricker, Jay H. Hendricks
The next-generation pressure standards will be realized via gas density and the equation of state. One way to access the density is through a measurement of gas refractivity, underpinned by the theoretical calculations that predict the relationship between

Daniel I. Maser, Gabriel G. Ycas, William I. Depetri, Flavio Caldas da Cruz, Scott A. Diddams
A tunable mid-infrared frequency comb was created via diff erence frequency generation. Pulses between 1 and 1.5 μm were mixed to make idlers of 2.6-5.2 μm. Two such combs were heterodyned at 5 μm to show their coherence and potential for spectroscopy.

Electric-Field Induced Reversible Switching of the Magnetic Easy Axis in Co/BiFeO 3 on SrTiO 3

Tieren Gao, Xiaohang Zhang, William D. Ratcliff, Shingo Maruyama, Makoto Murakami, Anbusathaiah Varatharajan, Zahra Yamani, Peijie Chen, Ke Wang, Huairuo Zhang, Robert D. Shull, Leonid A. Bendersky, John Unguris, R. Ramesh, Ramamoorthy Ramesh, I. Takeuchi
We demonstrate reversible electric-field-induced switching of the magnetic state of the Co layer in Co/BiFeO 3 (BFO) (001) thin film heterostructures fabricated on (001) SrTiO 3 substrates. The angular dependence of the coercivity and the remanent

Mobile Manipulator Stability Measurements

April 18, 2017
Author(s)
Roger V. Bostelman, Tsai H. Hong
Mobile manipulators are being marketed for material handling and other tasks. Manufacturers suggest the stability of the vehicle best when the onboard loading tapers the centroid to the center of the wheelbase as the payload height increases. Experiments

Structural Features and Lipid Binding Domain of Tubulin on Biomimetic Mitochondrial Membranes

April 18, 2017
Author(s)
David Paul Hoogerheide, Sergei Y. Noskov, Daniel Jacobs, Lucie Bergdoll, Vitalii Ivanovich Silin, David L. Worcester, Jeff Abramson, Hirsh Nanda, Tatiana K. Rostovtseva, Sergey M. Bezrukov
Amphitropic proteins, the subfamily of peripheral membrane proteins that interact directly with lipid bilayers, comprises members whose function depends on their localization either in the cytosol or at the cellular membranes. Despite the well-established

Towards a Platform for Community-centric Smart Connected Services

April 18, 2017

Eswaran Subrahmanian, Ram D. Sriram, Ramesh Jain
All cities can be seen as a collection of commons. Commons are spaces, services and resources shared by the citizenry. Any change in the state of any one of the commons could lead to a potential action or actions. In this paper we illustrate the use of a

UV-sensitive superconducting nanowire single photon detectors for integration in an ion trap

April 17, 2017
Author(s)
Daniel H. Slichter, Varun B. Verma, Dietrich G. Leibfried, Richard P. Mirin, Sae Woo Nam, David J. Wineland
We demonstrate superconducting nanowire single photon detectors with 76 +/- 4% system detection efficiency at a wavelength of 315 nm and an operating temperature of 3.2 K, with a background count rate below 1 count per second at saturated detection

The dependence of electrical performance on structural organization in low mobility polymer field effect transistors

Author(s)
Emily G. Bittle, Hyun W. Ro, Chad R. Snyder, Sebastian Engmann, Regis J. Kline, Oana Jurchescu, Dean M. DeLongchamp, David J. Gundlach
Polymer semiconductors are contenders for use in printed, flexible electronics. Though organic electronic materials have been studied for many years, the physics of charge transport is still under investigation. This is in part due to the large variability

Economics of Additive Manufacturing

April 15, 2017
Author(s)
Douglas Thomas
There are three aspects to the economics of additive manufacturing. The first involves measuring the size of additive manufacturing. This includes measuring the value of the goods produced using this technology in the context of the total economy. The

CH3NH3PbI3 perovskites: Ferroelasticity revealed

Evgheni Strelcov, Qingfeng Dong, Tao Li, Jungseok Chae, Yuchuan Shao, Yehao Deng, Alexei Gruveman, Jinsong Huang, Andrea Centrone
Ferrolectricity has been proposed as a plausible meachanism to explain the high photovoltaic conversion efficiency in organic-inorganic perovskites; however, convincing experimental evidence in support to this hypothesis is still missing. Identifying and

Ising-Like Antiferromagnetism on the Octahedral Sublattice of a Cobalt-Containing Garnet and the Potential for Quantum Critically
