Local field effect on charge-capture/emission dynamics

October 30, 2017
Author(s)
Kin P. Cheung, Dmitry Veksler, Jason P. Campbell
Charge-capture/emission is ubiquitous in solid state devices. Its dynamics often play critical roles in device operation and reliability. Treatment of this basic process is found in many text books and is considered well understood. As in many solid state

Phase Competition in the Palmer-Chalker XY Pyrochlore Er 2 Pt 2 O 7

October 30, 2017
Author(s)
A. M. Hallas, J. Gaudet, Nicholas Butch, Guangyong Xu, M. Tachibana, C. R. Wiebe, Graeme M. Luke, Bruce D. Gaulin
We report neutron scattering measurements on Er 2Pt 2O 7, a new addition to the XY family of frustrated pyrochlore magnets. Symmetry analysis of our elastic scattering data shows that Er 2Pt 2Od7^ is the first XY pyrochlore to order into the κ = 0,Γ 7

Strength of Brittle Materials in Moderately Corrosive Environments

October 30, 2017
Author(s)
Robert F. Cook
The strengths of four brittle materials―cordierite glass ceramic, fused silica, silicon, and polycrystalline alumina were measured after exposure to weakly-corrosive water and moderately- corrosive buffered HF (BHF) solution. Exposure to water did not

Propagation of orientation uncertainty of 3D rigid object to its points

October 28, 2017
Author(s)
Marek Franaszek, Geraldine Cheok
If a CAD model of a rigid object is available, the location of any point on an object can be derived from the measured 6DOF pose of the object. However, the uncertainty of the measured pose propagates to the uncertainty of the point in an anisotropic way

Genome Replication in Thermococcus kodakarensis Independent of Cdc6 and an Origin of Replication

October 27, 2017
Author(s)
Alexandra Gehring, David Astling, Rie Matsumi, Brett Burkhart, Zvi Kelman, John Reeve, Kenneth Jones, Thomas J. Santangelo
The initiation of DNA replication is typically tightly regulated by proteins that form initiation complexes at specific sequences known as replication origins. In Archaea and Eukaryotes, Cdc6, a near-universally conserved protein binds and facilitates the

The odd-even invariant and Hamiltonian circuits in tope graphs

October 27, 2017
Author(s)
Yvonne Kemper, James F. Lawrence
Questions of the existence of Hamiltonian circuits in the tope graphs of central arrangements of hyperplanes are considered. Connections between the existence of Hamiltonian circuits in the arrangement and the odd-even invariant of the arrangement are

Strategies and Considerations for the Trace Detection of Fentalogs

October 26, 2017
Author(s)
Edward Sisco
Fentanyl and fentanyl analogs pose a significant and ever changing threat in the United States as both pure compounds and in complex mixtures. While commonly considered detection techniques require visible amounts of powder (i.e. color tests or GC/MS
