Magnetic phases of spin-1 spinorbit-coupled Bose gases

May 1, 2016
Author(s)
Ian B. Spielman, Daniel Campbell, Ryan Price, Ana Valdes-Curiel, Andika Putra, Dimitrius Trypogeorgos
Phases of matter are characterized by order parameters describing the type and degree of order in a system. Here we experimentally explore the magnetic phases present in a near-zero temperature spin-1 spin–orbit-coupled atomic Bose gas and the quantum

Membrane Binding of HIV-1 Matrix Protein: Dependence on Bilayer Composition and Protein Lipidation

May 1, 2016
Author(s)
Marilia Barros, Frank Heinrich, Siddhartha A. K. Datta, Alan Rein, Ioannis Karageorgos, Hirsh Nanda, Mathias Loesche
Retroviral Gag polyprotein is the structural determinant that assembles in a protein lattice on the host's plasma membrane to trigger formation of the viral protein/membrane shell. In this process, it employs multiple signals - electrostatic, hydrophobic

Probing the Interfacial Structure of Bilayer Plasma Polymer Films via Neutron Reflectometry

May 1, 2016
Author(s)
Yali Li, Andrew Nelson, Christopher D. Easton, David R. Nisbet, John S. Forsythe, Benjamin Muir, Dan A. Neumann
Bilayer plasma polymer (PP) films were examined using a combination of X-ray and neutron reflectometry and X-ray photoelectron spectroscopy to gain an understanding of the interfacial structures that form between the films. Three different PP films were

Analysis and Optimization based on Reusable Knowledge Base of Process Performance Models

April 29, 2016
Author(s)
Alexander Brodsky, Guodong Shao, Mohan Krishnamoorthy, Anantha Narayanan Narayanan, Daniel Menasce?, Ronay Ak
In this paper, we propose an architectural design and software framework for fast development of descriptive, diagnostic, predictive, and prescriptive analytics solutions for dynamic production processes. The proposed architecture and framework will

Diagnostics for geometric performance of machine tool linear axes

April 29, 2016
Author(s)
Gregory W. Vogl, M A. Donmez, Andreas Archenti
Machine tools degrade during operations, yet knowledge of degradation is elusive; accurately detecting degradation of linear axes is mainly a manual and time-consuming process. Thus, manufacturers need automated and efficient methods to diagnose the

Intensity Ratio of Resonant Raman Modes for (n,m) Enriched Semiconducting Carbon Nanotubes

April 29, 2016
Author(s)
Yanmei Piao, Jeffrey R. Simpson, Jason K. Streit, Geyou Ao, Ming Zheng, Angela R. Hight Walker
Relative intensities of resonant Raman spectral features, specifically the radial breathing mode (RBM) and G modes, of eleven chirality-enriched single-wall carbon nanotube (SWCNT) species were established under second-order optical transition excitation
